DETAILED DESCRIPTION
Further description will now be made in detail to the present patent application in combination with the figures:
As shown in the figures, the engine utilizes the memory metal springs as a power source. Any metal material that can be formed into a memory metal, such as nickel titanium alloy, can be used to form the shape of the springs. The springs are downwardly compressed by the gravity of an iron plate or multiple weights applied thereon, heated to bounce upward and return to their original shapes after being compressed, and then compressed again by the iron plate or the weights thereon after being cooled so as to move a driving stem up and down in continuous repeating cycles and thereby drive other machines to rotate or to move. The methods for heating the memory metal springs include: 1. the memory springs are heated by polyhedral glass balls, which collect sunshine at different angles and conduct heat to the memory springs through a heat-conducting rod; 2. the memory springs are heated by burning fuels and conducting the heat thereto through a heat-conducting rod; 3. the memory springs are heated by generating heat by electrical power and conducting heat thereto by a heat-conducting rod; 4. the memory springs are heated by collecting geo-heat from underground and conducting the geo-heat thereto through a heat-conducting rod; and 5. the memory springs are heated by generating heat by other means and conducting the heat thereto through a heat-conducting rod. A housing of the engine is a heat-insulating box. When the springs return to the original shapes and thereby push the iron plates or the weight upwards, blinds at four edges of the heat-insulating box are simultaneously lifted up so as to close the heat-insulating box. When the springs are pushed downwards by the iron plate or the weights, blinds at four edges of the heat-insulating box are simultaneously lowered so as to open the heat-insulating box. The heat-insulating box may be glued with heat-insulating tiles that are made of amorphous silicon reinforced fiber and high-temperature ceramic coating or any other materials so as to enhance its heat-insulating capability.
In FIG. 1, an iron plate or a weight plate (2) is disposed on memory springs (1) which are downwardly compressed under the action of the gravitational force (gravity), while the upper parts of the memory springs are connected with polyhedral glass balls (3) through metal rods (4), so that the heat is focused on the metal rods (4) by the polyhedral glass balls (3) and conducted to the memory springs (1) to make the memory springs (1) upwardly bounce and return to their original shapes. The lower parts of the memory springs (1) are connected with heat-conducting rods (5). The heat is conducted to memory springs (1) via the heat-conducting rods (5) and thereby makes the memory springs (1) return to their original shapes in other ways. A driving stem (6), which is used as a stem to drive other machines to rotate or move up and down and used for pressing a timer switch (13), is disposed on the center of the iron plate or the weight plate (2).
In FIG. 2, the four edges of a heat-insulating box (7) are provided with blinds (8), which are used for preventing the sunshine entering the inside of the heat-insulating box when the box is lifted. The blinds have opening gaps thereon for diffusing hot air out of the box. Triangular box covers (9) are arranged on the heat-insulating box (7). When the memory springs (1) are compressed by the iron plates or the weight plates thereon, the box cover (9) is positioned at a lower position and being perpendicular between 10 degrees to 20 degrees; when the memory springs (1) are heated to return to their original shapes and lifting up the box, the box cover (9) is positioned at a higher position and being completely closed and perpendicular between 40 degrees to 50 degrees. Simultaneously, the hot air in the box starts to be diffused out. The blinds (8) and the surfaces of the box covers (9) can be glued with heat-insulating tiles which are made of amorphous silicon reinforced fiber and high-temperature ceramic coating or any other materials to enhance heat-insulating capability.
In FIG. 3, a heater (10) may be a fuel tank, an electric furnace or a geo-heat reservoir. The heater is provided with a plurality of burner nozzles or heat-conducting cylinders (11) which are just tightly engaged with the heat-conducting rods (5). The center of the heater (10) is provided with a heater switch (15), above which a timer (12) is arranged. When the memory springs (1) are compressed by the iron plate or the weight plate (2) thereon, the driving stem (6) compresses a timer switch (13) to make the timer (12) start counting; when the memory springs (1) are heated to return to their original shapes and lifting up the driving stem (6), the driving stem (6) departs from the timer switch (13) to stop the timer (12) from counting. When the timer (12) starts to work and reaches a scheduled time, a timer driving stem (14) downwardly compresses the heater switch (15) so that the heater (10) heats the heat-conducting stem (5) via the burner nozzles or the heat-conducting cylinders (11), thereby making the memory springs (1) return to their original shapes.
In FIG. 4, a connecting rod (16) for connecting the weight plate (2) with the box is configured for driving the box to move up and down when the weight plate (2) moves up and down.
In FIG. 5, a steel ball tray (18) supporting a steel ball (17) is configured for fixing the steel ball (17) and rolling the steel ball (17) to a ball-entering pipe (19) by the method of turning the steel ball tray (18) one side up and one side down when the steel ball is at a highest position.
In FIG. 6, the steel ball (17) rolls into the steel ball tray (18) through the ball-entering pipe (19), which leads to an electricity-generating device, and downwardly pulls a chain belt (21). The chain belt (21) tightly pulls a tension spring (22). A positioning pipe (23) is arranged on the tension spring (22), and the center part of the chain belt (21) is assembled with a chain belt gear (24), which is stuck at the middle of a revolving track ring (25). When the chain belt (21) is downwardly pulled by the steel ball (17), simultaneously, the tension spring (22) is pulled away and the gear (24) is driven to revolve and rotate along the revolving track ring (25). The lower part of the gear (24) is provided with a bearing rod (26) under which a copper sheet (20) is provided. When the gear (24) rotates, the copper sheet (20) is driven to rotate simultaneously. When the chain belt (21) is pulled at the lowest position by the steel ball (17), the steel ball (17) rolls back to the engine again by the method of turning the steel ball tray (18) one side up and one side down through the ball-returning pipe (27) which leads to the engine. When the steel ball (17) departs from the steel ball tray (18), the tension spring (22) pulls the gear (24) back to the original position.
In FIG. 7, the connection portion of the driving stem (6) is arranged at a lower position, which can be connected with an electricity generator conveniently.
In FIG. 8, when the driving stem (6) moves up and down, a pivoted lever (28) is driven to round rotate, thereby causing a main gear and a pinion gear (29) connected therewith to rotate. The pinion gear is tightly locked with the circular copper sheet (20).
In FIG. 9, the circular copper sheet (20) is in close proximity of a U-shaped magnet (30) around which a copper wire (31) is winded. When the circular copper sheet (20) rotates to cut the magnetic lines of force, electric charge is generated and so is electric current while the copper wire (31) functions as a media.
