Alternatively, the auxiliary water inlet pipe 30 is communicated with the warm air inlet pipe of the chassis engine 1, and the auxiliary water outlet pipe 31 is communicated with the warm air outlet pipe of the chassis engine 1. The chassis power take-off power generation pickup truck drainer 100 of this embodiment is configured with an auxiliary radiator 5 to solve the problem that the chassis engine 1 cannot work properly due to insufficient heat dissipation capacity of the chassis caused by parking power take-off power generation during the working condition of driving a high-power drainage device for a long time. When the parking power take-off power generation operates a high-power water pump 6, turning on the switch 42 of the auxiliary radiator control system on the main control cabinet 32 can solve the high-temperature phenomenon of the chassis engine 1.

[0038] The chassis power-taking and power-generating pickup truck 100 of the present embodiment uses the chassis engine 1 of the pickup truck itself as the original power source, and then drives the power generating device after being hard-connected to the speed-changing and pitch-changing device through the power-taking transmission device, so as to provide power to the electric load equipment of the whole vehicle. The power of the provided power generating device can reach 70% of the power of the chassis engine 1, and the configured auxiliary radiator 5 can increase the heat dissipation capacity of the chassis engine 1 during operation, so as to allow the electric load equipment of the whole vehicle to operate for a long time, and solve the defect of not being able to operate for a long time due to insufficient heat dissipation capacity. In addition, the chassis engine speed stabilization module in the configured master control system can allow the output speed of the chassis engine 1 to be constant at a value when the whole vehicle is taking power for power generation, and this value matches the input speed of the power generating device, so that the power generating device can generate electricity normally, and the output voltage is not affected by the power size of the electric load, so as to achieve matching with each constant speed power generating device.

[0039] The chassis power-taking pickup truck drainage vehicle 100 of this embodiment has a clear spatial layout of the rear cargo box 16. The space of the rear cargo box 16 is very sufficient. Except for the area where the speed change device is located, the area where the power generation device is located, the area where the master control system is located, and the area where the auxiliary radiator 5 is located (located above the storage area 34), other areas (water pump control area 33, storage area 34, drainage pump area 35) can be flexibly mobilized, equipped with emergency rescue equipment, and can accommodate two sets of drainage devices commonly used in the market.
