In one embodiment, the high pressure nozzle 31 is placed just above a hole or opening on the upper end of the second pipe 17. The high pressure nozzle 31 will spray hot water into the second pipe 17 through the hole or opening. The high pressure pump 30 will cause the hot water to be released from the high pressure nozzle 31 at a very high velocity.
In one embodiment, the water heater 29 can be a tankless water heater 29. Due to the enclosed environment of the vehicle, a generator or an alternator may be needed to power the water heaters 29, any water pumps installed in the vehicle, and any other auxiliary motors. Using propane to heat he water heater 29 is also possible.
In one embodiment, excessive water can be released back into the environment when ambient temperature is above 35 F or dumped into the drainage system from the water tank 21 through a release device.
In an embodiment of the invention the snow removal vehicle can comprise at least two water heaters 29, a first water pump 25 placed inside the water tank 21, a second water pump 26 placed inside the water tank 21, and at least one water filter screen 24.
In this embodiment, the first water pump 25 pumps the water in the water tank 21 to at least one water heater system 28. The second water pump 26 pumps the water from the water tank 21 to an additional storage tank. The second water is placed at a higher elevation than the first water pump 25, and the second water pump 26 will be turned on only when the water level inside the water tank 21 reaches it. This arrangement allows the second water pump 26 to be turned off when water level in the water tank 21 is relatively low thus a certain amount of water will always be left inside the water tank 21 to feed the water heater system 28.
In this embodiment, water tank 21 can further comprise at least one filtration means 23. When the water passes through the filtration means 23, various debris are collected by the filtration means 23 to keep the water clean. Clean water can help protect the water pumps and the water heater system 28 to allow the mechanism longer service life.
In this embodiment, the filtrations means can comprise at least two filtration screens with decreasing mesh size. Larger debris can be trapped by the filtration screens with larger mesh size and smaller debris can be trapped by the filtration screens with smaller mesh size. This arrangement allows the filtration means 23 to work more efficiently by distributing the debris to more than one filtration screens. The first water pump 25 can be placed behind the filtration screen with the smallest mesh size water which goes to the water heater system 28 and high pressure nozzle 31 must be the cleanest because the mechanisms can be very sensitive.
In this embodiment, there can be at least two water heaters 29 connected in series. The first water heater 29 in the series heats the water to a predetermined temperature, and each of the next water heaters 29 in the series heats the water to a higher temperature than the water in the previous water heater 29. For example, the first water heater 29 in the series heats the water from 40° F. to 90° F., and the second water heater 29 in the series heats the water from 90° F. to 120° F. The arrangement allows the water heater system 28 to work more efficiently, and water can be heated to a higher temperature.
In an embodiment of the invention, the snow removal vehicle can further comprise at least one secondary water tank 21 to receive water from the second water pump 26. Due to the limited size of the water tank 21, additional storage may be needed to hold the excessive water. A secondary water tank 21 can be attached to the snow removal vehicle. A water pipe will be running from the secondary water tank 21 to the second water pump 26. When the water level inside the water tank 21 reaches the second water pump 26, the second water pump 26 will pump the water into the secondary water tank 21 through the water pipe. The secondary water tank 21 will act as additional storage for water that cannot be held inside the water tank 21 and cannot be release into the environment.
In one embodiment, excessive water can also be released back into the environment when ambient temperature is above 35° F. or dumped into the drainage system through a drainage spout 27 on the storage tank.
In another embodiment, an additional ice melting chemical distribution system or device can be attached to the secondary water tank 21. The ice melting chemical distribution system or device distribute chemicals such as salt, calcium chloride, magnesium chloride solution or other ice melting chemicals. The ice melting chemical distribution system or device can dispense the said chemical into the environment to prevent ice from freezing on roadways, parking lots or other surfaces.
The method of implementing the snow removal vehicle best demonstrated by describing the path of the snow as it interacts with the snow removal vehicle. The snow will be first collected by the snow collection means 2 from the environment. A snow conveyance means 9 will transfer the snow from the snow collection means 2 to a water tank 21. While the snow is still in the snow conveyance means 9, hot water from the water heater system 28 is applied to the snow. Once the snow reaches the water tank 21, it should have been melted into water. The water created by the melted snow is recycled back into the water heater system 28 to create more hot water. When the amount of water in the water tank 21 reaches a certain capacity, the water will be pumped into a secondary water tank 21 for temporary storage.
In an embodiment of the invention, the snow collection means 2 can comprise a collection auger 3, a hydraulic system 5, at least one hydraulic unit, at least one motor, a force transfer mechanism, a separator 7, and an exit opening 6.
The collection auger 3 collects snow from the environment such as the road or the parking lot. In order to place the collection auger 3 at the most optimal positions to collect snow from the environment, the motor will work in conjunction with the hydraulics and force transfer mechanism can move the collecting means in vertical, horizontal and longitudinal directions. The distance between the collection housing 4 and the vehicle mount 8 can be reduced to save space.
In this embodiment, there is also a hydraulic system 5 that can be expanded to different width and used as a wedge to push snow into the collection auger 3. The hydraulic system 5 can be adjusted according to the width of the road to fit a particular snow removal mission. There can also be a separator 7 to keep large object from entering the auger. Often, there could be large animal carcass or rocks on the road. If those objects can damage the snow collection means 2 by entering into the collection auger 3. Therefore, a separator 7 comprising vertical metal slates or wire screen is needed to keep the objects out.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
