[0014] As Figs. 1-3 The utility model discloses a kind of upper installation power device for pure electric dust suppression vehicle, including chassis 1 and tank body 2 on chassis 1, fog gun 3, fan motor 4, lifting cylinder 5, slewing mechanism 6 and power assembly 9.Fog gun 3 is connected to slewing mechanism 6, fog gun 3 is rotated left and right by slewing mechanism 6, lifting cylinder 5 is connected to slewing mechanism 6 and drives fog gun 3 to lift and descend;Fan motor 4 is used to drive the rotation of fan blade in fog gun 3;Power assembly 9 includes double-end output motor 902, gear pump 903, water pump 901 and two-in-one controller 904, the front end of double-end output motor 902 is directly connected with water pump 901, water pump 901 supplies water for road surface watering operation and spray dust-settling operation, the rear end of double-end output motor 902 is directly connected with gear pump 903, gear pump 903 provides power for hydraulic system, and hydraulic system is used to drive lifting cylinder 5 and slewing mechanism 6 to act;Two-in-one controller 904 is used to control the rotation of double-end output motor 902 and fan motor 4.

[0015] The upper-mounted power device is powered by a battery control system on the bottom plate 1. The battery control system is electrically connected to the two-in-one controller 904 through a high-voltage line, and the two-in-one controller 904 is electrically connected to the double-head output motor 902 and the fan motor 4 through high-voltage lines respectively. The double-head output motor 902 drives the water pump 901 and the gear pump 903 simultaneously, and the initial state of the hydraulic system is a pipeline oil return state, that is, the hydraulic oil directly returns to the hydraulic oil tank after passing through the hydraulic pipeline 8 after passing through the gear pump 903.

[0016] The operation mode is manual control gear selection, which increases the operation safety. When the operation gear of the cab control panel is set to the road surface watering operation gear, the fan motor 4 does not operate, the water outlet ball valve on the fog gun 3 is closed, the water outlet ball valves of the watering nozzles of each part are opened according to the operation needs, the two-in-one controller 904 controls the double-head output motor 902 to adjust the speed to a speed suitable for road surface watering operation, the water pump 12 sends the clean water in the tank 2 into the water pipeline 7, and the watering operation is performed through each nozzle; when the operation gear of the cab control panel is set to the spraying dust-settling operation gear, the water outlet ball valves of each watering nozzle are closed, the water outlet ball valve on the fog gun 3 is opened, the fan motor 4 starts to operate, the two-in-one controller 904 controls the double-head output motor 902 to adjust the speed to a speed suitable for spraying dust-settling operation, and the water pump 901 sends the clean water in the tank 2 into the water pipeline 7, and the spraying dust-settling operation is performed through the fog gun 3. The speeds of the road surface watering operation and the spraying dust-settling operation can be adjusted on the basis of the initial operation speed, and the water spraying amount can be steplessly adjusted according to the actual operation condition, and the fog gun 3 can also steplessly adjust the air volume according to the actual condition.

[0017] The lifting oil cylinder 5 and the rotating mechanism 6 lift and lower the fog gun 3 and rotate the fog gun 3 left and right, and are driven by the hydraulic system. When the fog gun 3 is lifted, lowered and rotated left and right, the two-in-one controller 904 controls the double-head output motor 902 to adjust the speed to a reasonable speed, opens the hydraulic electromagnetic valve, and the hydraulic oil enters the lifting oil cylinder 5 and the rotating mechanism 6 through the hydraulic pipeline 8, so that the fog gun 3 rotates and lifts. To ensure the safe operation of each operation mechanism and the driving safety of the driver, when in the road surface watering operation gear, the fog gun 3 cannot be operated, only the water outlet ball valves on the water pipeline 7 can be operated, and the water pump 901 operates without linkage with the driving speed of the bottom plate 1, so that the driver can focus on driving during the road surface watering operation and does not need to consider the watering amount of the nozzle; when in the spraying dust-settling operation gear, the water outlet ball valves on the water pipeline 7 are closed and cannot be operated, the fan switch and the water outlet switch are separately arranged on the operation panel, the fan switch is opened only when blowing air without spraying water is needed, the water outlet switch is opened only when spraying water without blowing air is needed, the fan switch and the water outlet switch are opened simultaneously when normal spraying dust-settling operation is performed, and the lifting and lowering and left and right rotation of the fog gun 3 can be controlled only by operating the rocker in the spraying dust-settling operation gear.
