Working principle: the novel energy automobile is a municipal vehicle and is used for sprinkling dust and simultaneously can be used for snow shoveling in winter, therefore, a water bucket 24 is arranged in a carriage behind the municipal vehicle, when the sprinkling dust and falling automobile is used for sprinkling dust and falling in summer, a valve No. 26, a valve No. 27 and a valve No. three 28 are all in a normally-closed state, a valve No. 29 is in a normally-open state, a water spray port 25 is directly pumped from the water bucket 24 to spray water into the air, if a general controller receives that the internal temperature of a battery box 3 is higher than the upper limit value of a preset temperature, the general controller controls to close the valve No. 29, simultaneously opens a water control valve 13, the valve No. 26 and the valve No. three 28, at this time, when the water in the water spray port 25 is pumped, water in the water bucket 24 enters a water tank pipeline 9 through a water tank 4 and enters the water spray port 25 through a water outlet of the water tank pipeline 9, when water in the water tank 4 passes through the inside of the battery box 3 in the water tank pipeline 9, due to the heat transfer principle, the heat in the battery box 3 is gradually taken away from the battery box 3, the effect of cooling the inside of the battery box 3 is realized, the electric telescopic rod 22 is in a normally closed state, the normally closed state is a contracted state, therefore, the movable plate 21 is overlapped with the corresponding fixed plate 20, the temperature in the battery box 3 can be subjected to normal heat dissipation, if the outdoor temperature is higher, the temperature in the battery box 3 can be increased, the electric telescopic rod 22 is controlled to be opened by the master controller, the electric telescopic rod 22 pushes the movable plate 21, the movable plate 21 and the fixed plate 20 are completely staggered, the battery 18 is fully sealed, the movable plate 21 and the fixed plate 20 are both heat-insulating plates, and therefore the battery box 3 is insulated, and hot air in the air is prevented from heating the inside the battery box 3.
The second liquid control valve 15 is in a normally closed state, the first liquid control valve 14 is in a normally open state, at this time, the cooling liquid flowing out of the motor 2 enters the first branch pipe 8 through the cooling liquid pipe 7, and enters the radiator 6 through the first branch pipe 8, cooling treatment is carried out on the cooling liquid through the refrigerating system inside the radiator 6, so that the cooling liquid continuously circulates to refrigerate the motor 2, when the water passing through the water bucket 24 is cooled for the battery box 3, the temperature inside the battery box 3 is lower than the preset upper temperature limit value, the second liquid control valve 15 is controlled by the master controller, the first liquid control valve 14 is closed, the working strength of the refrigerating system of the radiator 6 is reduced, at this time, the cooling liquid flowing out of the motor 2 enters the battery box 3 through the cooling liquid pipe 7, the primary cooling inside the battery box 3 reenters the inside the radiator 6, the cooling liquid is quickly cooled to a lower temperature through the secondary cooling inside the radiator 6, the cooling liquid continuously enters the liquid storage box 5 to circularly cool the motor 2, the cooling liquid pipe 18 in the water bucket 24 is fully utilized, the water temperature of the battery box 18 is cooled, the electric power consumption is reduced through the cooling liquid in the battery box 3, and the cooling system is reduced.
If there is no water or the water temperature is too high in the bucket 24 and can not effectively cool the interior of the battery box 3, the master controller controls to close the water control valve 13, the first valve 26 and the third valve 28, opens the second valve 27 to form water in the water tank 4 to supply water to the water tank pipeline 9 for internal circulation, at the moment, the refrigerator 16 is opened by the master controller at the same time, so that the refrigerator 16 refrigerates the water in the water tank 4 to ensure that the temperature in the battery box 3 is within a preset upper temperature limit value, if an emergency is met, the upper refrigeration limit of the radiator 6 still can not completely cool the heat generated in the motor 2 to be within the preset upper temperature limit value, the master controller still opens the second liquid control valve 15 to close the first liquid control valve 14, meanwhile, the cooling speed of the refrigerator 16 is improved, the cooling liquid enters the battery box 3 through the liquid cooling pipeline 7 for preliminary cooling, and then enters the radiator 6 for cooling, so that the refrigerator 16 assists the cooling liquid in cooling the cooling liquid, the cooling liquid in the motor 2 is ensured to be within the upper temperature limit value, and the service life of the motor 2 is prevented from being reduced due to the fact that the temperature of the motor 2 is too high.
When the air temperature is lower to be close to 0 ℃, water in the water tank 4 and the water tank pipeline 9 is required to be discharged, when the weather is cold, the water is prevented from freezing to prop the water tank 4 and the water tank pipeline 9, meanwhile, the main controller sets the electric telescopic rod 22 to be in a normally open state, so that the electric telescopic rod 22 pushes the movable plate 21 out to a city surrounding with the fixed plate 20, and the battery 18 is protected by heat preservation.
When the internal temperature detector of the battery box 3 received by the master controller detects that the internal temperature of the battery box 3 is lower than the preset temperature lower limit value, the master controller controls to close the first liquid control valve 14 and simultaneously opens the second liquid control valve 15, so that the cooling liquid flowing out of the motor 2 passes through the battery box 3 through the cooling liquid pipeline 7, part of heat is taken out through the cooling liquid of the motor 2 in the process, when the internal temperature of the battery box 3 is increased by gradually heating the internal temperature of the battery box 3 through the heat on the cooling liquid pipeline 7, the internal temperature of the battery box 3 is higher than the preset temperature lower limit value, and when the cooling liquid in the process enters the radiator 6 again, the temperature is reduced by a lot, only a small or no refrigerating system is needed to work, the cooling liquid can meet the cooling of the motor 2, the process realizes the work energy consumption of the refrigerating system of the radiator 6, and simultaneously plays a role of heat preservation on the battery 18 in the battery box 3 by utilizing the heat generated when the motor 2 works.
If the temperature inside the battery box 3 is close to the preset upper limit value of the temperature inside the battery box 3 in the process of heating the battery box 3 by utilizing the heat carried by the cooling liquid, the master controller opens the air inlet valve 11, and performs appropriate temperature reduction on the inside of the battery box 3 through the air inlet valve 11, so that the inside temperature of the battery box 3 is prevented from being too high, if the air pump 23 and the air inlet valve 11 are opened through the master controller in the snow shoveling process, the air pump 23 sucks the heat inside the battery box 3 into the tail end of the air pipeline 10 through the air pipeline 10, and blows hot air to the bottom surface of the bottom of the front wheel through the tail end of the air pipeline 10, so that slight melted water caused by friction between snow shoveling tools and the bottom surface is prevented from being frozen when snow shoveling, the forklift is not easy to run forward, and if the inside temperature inside the battery box 3 is close to the preset lower limit value, the master controller controls the air pump 23 to be closed, so that the inside temperature inside the battery box 3 is prevented from being too low, and the service life of the battery 18 is prevented from being damaged.
