Patent Description:
A turbocharger is an air compressor driven by a structure including two coaxial impellers through the exhaust gas generated in operation of an internal combustion engine. Similar to a supercharger, the turbocharger can increase the air flow into the internal combustion engine or boiler, so as to improve the combustion efficiency. The turbocharger is commonly found in an automotive engine, where it uses the heat and flow of the exhaust gas to increase the output power of the internal combustion engine or improve fuel economy at the same output power.

However, the turbocharger is not suitable for a hydroelectric generator. Therefore, it is highly desirable to develop a device for increasing the efficiency of the hydroelectric generator by using hydraulic power, in order to resolve most if not all of the problems existing in the prior art. <CIT> discloses a hydraulic energy converter, wherein a turbine stage comprises a first turbine rotor which carries an internal gear and a second turbine rotor which carries planetary gears. One or more such turbine stages are mounted on a common pinion shaft in such a way that the first and second turbine rotors alternate. The first and second turbine rotors have blades which are right-handed and left-handed, respectively, so that they are rotated in opposite directions. <CIT> discloses a turbine power generation device for water conservancy and hydropower, wherein when working, first the water flows into a water flow chamber through a water inlet, and impacts a turbine plate to cause the turbine plate to rotate. At the same time, a limiting block limits the water flow to the middle of the surface of the turbine plate. Then the turbine plate rotates to drive a rotating shaft to rotate, the rotation of the rotating shaft drives the rotation of a rotor.

It should be understood that the terms, such as "have", "include" and "comprise" as used herein, do not exclude the presence or addition of one or more other elements or a combination thereof.

As shown in <FIG>, the present invention provides a power converter having a boosting mechanism with a multi-shaft vertically stepped turbine.

The power converter includes: shaft sleeve <NUM>, water inlet end base <NUM>, outer sleeve <NUM>, a plurality of first stepped turbine units <NUM>, a plurality of first shaft rods <NUM>, a plurality of second stepped turbine units <NUM>, a plurality of second shaft rods <NUM>, and third shaft rod <NUM>. The water inlet end base <NUM> is provided on an upper end of the outer sleeve <NUM>. The shaft sleeve <NUM> is provided inside the outer sleeve <NUM>, and an upper end of the shaft sleeve <NUM> extends out of the water inlet end base <NUM>. The water inlet end base <NUM> is provided with a plurality of water inlet holes <NUM>. The first shaft rods, the second shaft rods and the third shaft rod <NUM> are nested inside the shaft sleeve <NUM>. The third shaft rod <NUM> is provided in a central part of the shaft sleeve <NUM>. The plurality of first shaft rods <NUM> and the plurality of second shaft rods <NUM> are alternately and uniformly distributed around the third shaft rod <NUM>. The plurality of first stepped turbine units <NUM> are sequentially arranged on the first shaft rods <NUM> and the second shaft rods <NUM> from top to bottom. The first stepped turbine units <NUM> are drivingly connected to the first shaft rods <NUM>, and are rotatably connected to the second shaft rods <NUM>. The plurality of second stepped turbine units <NUM> are sequentially arranged on the first shaft rods and the second shaft rods from top to bottom. The second stepped turbine units <NUM> are drivingly connected to the second shaft rods, and are rotatably connected to the first shaft rods. The first stepped turbine unit <NUM> is located above the second stepped turbine unit <NUM>, and the second stepped turbine units <NUM> and the first stepped turbine units <NUM> rotate in opposite directions.

A working principle of the above technical solution is as follows. In the present invention, the power converter is vertically connected to an input end of a hydraulic/steam engine during operation. Specifically, the power converter includes the shaft sleeve <NUM>, the water inlet end base <NUM>, the outer sleeve <NUM>, the plurality of first stepped turbine units <NUM>, the plurality of first shaft rods <NUM>, the plurality of second stepped turbine units <NUM>, the plurality of second shaft rods <NUM>, and the third shaft rod <NUM>. The water inlet end base <NUM> is provided with the plurality of water inlet holes <NUM>. The water inlet holes <NUM> are connected to a water supply pipe. The water supply pipe conveys water to the outer sleeve <NUM> through the water inlet holes <NUM>. Under the action of gravity, the water flows downwards and impacts the plurality of first stepped turbine units <NUM> and the plurality of second stepped turbine units <NUM> located below the shaft sleeve <NUM> in the outer sleeve <NUM>. For example, there are three first stepped turbine units <NUM> and three second stepped turbine units <NUM>. The first stepped turbine unit <NUM> is located above the second stepped turbine unit <NUM>. That is, the three first stepped turbine units <NUM> and the three second stepped turbine units <NUM> in a vertical direction are arranged alternately with each other. That is to say, the first stepped turbine units <NUM> are respectively arranged at layers "<NUM>", "<NUM>", and "<NUM>", and the second stepped turbine units <NUM> are respectively arranged at layers "<NUM>", "<NUM>", and "<NUM>". The second stepped turbine units <NUM> and the first stepped turbine units <NUM> are designed in reverse structures. Under the action of water impact, the first stepped turbine units <NUM> located at the layers "<NUM>", "<NUM> ", and "<NUM>" are rotated in a same direction, such as clockwise, while the second stepped turbine units <NUM> located at the layers "<NUM>", "<NUM>", and "<NUM>" are rotated in another direction, such as counterclockwise. Thus, during a drainage process, when the first stepped turbine units <NUM> and the second stepped turbine units <NUM> rotate in opposite directions, water flows move in opposite directions and collide with each other. The three first stepped turbine units <NUM> are rotated synchronously through the plurality of first shaft rods <NUM> to fully absorb the potential energy and gravity energy of the water flow, thereby improving the working efficiency of the hydraulic/steam engine. Similarly, the three second stepped turbine units <NUM> are rotated synchronously through the plurality of second shaft rods <NUM> to absorb the potential energy and gravity energy of the water flow, thereby improving the working efficiency of the hydraulic/steam engine.

The above technical solution has the following beneficial effects. Through the above structural design, the power converter includes the shaft sleeve <NUM>, the water inlet end base <NUM>, the outer sleeve <NUM>, the plurality of first stepped turbine units <NUM>, the plurality of first shaft rods <NUM>, the plurality of second stepped turbine units <NUM>, the plurality of second shaft rods <NUM>, and the third shaft rod <NUM>. The first stepped turbine units <NUM> and the second stepped turbine units <NUM> are designed in reverse structures. During a drainage process, the water flows move in opposite directions and collide with each other to increase a water pressure. Due to the increase in the water pressure, rotational speeds of the first stepped turbine units <NUM> and the second stepped turbine units <NUM> increase, and rotational speeds of the first shaft rods <NUM> and the second shaft rods <NUM> correspondingly increase. In this way, two groups of power are output to the hydroelectric generator, thus improving the working efficiency of the hydroelectric generator.

In an embodiment, each of the first stepped turbine units <NUM> includes a first gear set, a first triangular stepped gear base, first gear sleeve <NUM>, and a plurality of first blades <NUM> with zero-clearance full-round projection.

A working principle of the above technical solution is as follows. In this embodiment, there are three first shaft rods <NUM> arranged in an equilateral triangular distribution around the third shaft rod <NUM> at an interval of <NUM>°. There are three second shaft rods <NUM> arranged in an equilateral triangular distribution around the third shaft rod <NUM> with an interval of <NUM>°. That is to say, the three first shaft rods <NUM> and the three second shaft rods <NUM> are alternately distributed around the third shaft rod <NUM>.

Specifically, the first stepped turbine units <NUM> each include the first gear set, the first triangular stepped gear base, the first gear sleeve <NUM>, and the plurality of first blades <NUM>. The plurality of first blades <NUM> are diagonally distributed along an outer wall of the first gear sleeve <NUM>. The water impacting from above drives the plurality of first blades <NUM> to rotate. The first blades <NUM> drive the first gear sleeve <NUM> to rotate. The first gear sleeve <NUM> drives the plurality of first internal gears <NUM> on the first triangular stepped gear base to rotate. There are three first internal gears <NUM> arranged. Since the first shaft rods <NUM> pass through the first internal gears <NUM>, when the first internal gears <NUM> are rotated, they drive the first shaft rods <NUM> to rotate. The water flows through the first stepped turbine unit <NUM> to reach the second stepped turbine unit <NUM>. The rotation direction of the second stepped turbine unit <NUM> is opposite to that of the first stepped turbine unit <NUM>. Therefore, the first stepped turbine unit <NUM> drives the second shaft rod <NUM> to rotate. That is to say, the rotation direction of the first shaft rod <NUM> is opposite to that of the second shaft rod <NUM>. The first stepped turbine units <NUM> located at the layers "<NUM>", "<NUM>", and "<NUM>" act on the three first shaft rods <NUM> in the triangular distribution to fully absorb the potential energy and gravity energy of the water flow, and the three first shaft rods <NUM> in the vertical direction output the power.
