The working principle of the utility model is: the engine drives the hydraulic pump to generate hydraulic energy, which is switched through the valve to: (1) support the crawler motor; (2) support the tire landing; (3) support the water pump landing gear; (4) Support the left and right hydraulic motors to drive the centrifugal pump. The cab, engine, and hydraulic station are respectively placed above the frame, and the hydraulic pump is driven by the engine speed to generate hydraulic energy, which enters the cab through the hydraulic pipe, distributes it through the manual valve, and distributes it to the required actuators to complete the above functions. When the landing gear enters the water deeply, a spare steel corrugated pipe can be connected to the water inlet pipe to achieve the purpose of drainage.

When the utility model is running on a normal road, the tire wheels are on the ground, and other trailers are allowed to pull the frame forward. At this time, speed and convenience are great advantages. Continue to move forward, and carry out drainage operations in order to reach the working section in time and quickly.

The utility model has the following beneficial effects:

1. The pumping station adopts double-drive tire wheels and crawlers to ensure that the pumping station can pass through the road under normal conditions and bad conditions, and it is truly a mobile pumping station;

2. The pump unit adopts a centrifugal pump, which greatly enhances the pumping capacity. At the same time, the water pipe has three outlets, which increases the water output;

3. The use of the hydraulic mechanism increases the effectiveness of the overall device, and the structure is reasonable and easy to use.

To sum up, the utility model is flexible and adaptable to the working environment, and at the same time can reduce the investment and danger of setting up a temporary power supply in bad weather.
