In order to protect the control panel 8, a cover 131 for shielding the control panel 8 is hingedly connected to the protection plate 13. Specifically, the hinged portions 132 are arranged at both ends of the protection plate 13, and the connecting portions 1311 are arranged at both ends of the cover 131 corresponding to the positions of the hinged portions 132. The hinged portions 132 and the connecting portions 1311 are both provided with corresponding through holes. The cover 131 can be rotated relative to the hinged portions 132 of the protection plate around the hinged shaft (not shown in the figure) penetrating through the through holes. In order to prevent the hinged shaft from falling off, the hinged shaft can be fixed by using nut, clasp spring and other fixing devices at both ends.

[0023] When the device is delivered to the use site, first start the vacuum pump 7 through the control panel 8, the circuit board 73 controls the motor 71 to rotate, at this time the reciprocating piston movement in the air pump pipe 72, in order to form a sealed condition, the water outlet valve 321 is arranged at the water outlet 32, and the water outlet valve 321 is kept closed when the vacuum pump 7 works. In this embodiment, the air pump pipe 72 is provided with pump head 721 at both ends, the air inlet 7211 and the air outlet 7212 are arranged on the pump head 721 respectively, and the one-way valve (not shown in the figure) is arranged at one end of the air outlet 7212 of the pump head 721. The air inlet 7211 and the air outlet 7212 are connected with each other through the conduit 10, and the conduit 10 is connected with the connecting pipe 6 through the three-way valve 101. The one-way valve in the pump head 721 is used for exhausting air. The air inlet 7211 and the air outlet 7212 are arranged at both ends of the air pump pipe 72 respectively, which is convenient for gas suction and exhaust, so that the vacuum pump 7 forms stable air flow circulation to generate vacuum. The one-way valve arranged at the air outlet 7212 end can avoid gas backflow, ensure the vacuum degree of the vacuum pump 7 to be stable and continuous, improve the water diversion efficiency and reliability, and prevent water diversion failure or delay caused by gas backflow. The air inlet 7211 and the air outlet 7212 are connected with each other through the conduit 10, which optimizes the air flow channel inside the air pump pipe 72, so that the gas flows more smoothly. When the gas enters from the air inlet 7211, it will flow along the path of the conduit 10 and mix and redistribute with the gas entering from other air inlets at the staggered connection. This staggered connection helps to form a more uniform and stable flow state inside the air pump pipe 72. The conduit 10 is connected with the connecting pipe 6 through the three-way valve 101, which realizes efficient air flow distribution and conduction between the air pump pipe 72 and the vacuum pump 7, guarantees the stable and efficient vacuum extraction process, greatly improves the water diversion reliability and efficiency of the whole pump group, effectively prevents water diversion failure or delay caused by gas backflow and other problems, and guarantees the stable vacuum extraction process.

[0024] With the continuous and stable operation of the vacuum pump 7, the air near the water inlet 31 of the water pump 3 is continuously and strongly pumped out through the vacuum pipe connecting seat 5 and the connecting pipe 6, so that the air pressure at the water inlet 31 is rapidly reduced, and a nearly perfect vacuum environment is gradually formed. The atmospheric pressure outside the water inlet 31 is pressed into the water inlet 31 through the filter screen 311, and at this time the gasoline engine 2 is started to start the water pump 3 to work. In order to prevent foreign matter from damaging the water pump 3, a filter screen 311 is arranged at the water inlet 31. The filter screen 311 of the water inlet 31 can not only ensure smooth water flow, but also effectively filter impurities such as sand, water grass fragments and small stones in the water, prevent them from entering the inside of the water pump 3, reduce the risk of wear and blockage of the water pump 3, and prolong the service life of the water pump 3. After a long time of use, some difficult-to-remove filtered materials will inevitably accumulate on the filter screen 311, so at this time the filter screen 311 can only be replaced, so in this embodiment, the filter screen 311 and the water inlet 31 are designed to be detachably connected. Through the detachable connection, when the filter screen 311 has too much filtered material, the filter screen 311 can be checked before the water inlet 31 is connected to the water pipe. If the filtered material is too much to clean, the filter screen 311 can be replaced. In this embodiment, the gasoline engine 2 can be started manually and electrically. When in remote areas or in emergency situations, the manual starting function can be used when the power supply is insufficient. The operator only needs to hold the manual switch 21 steadily, pull the manual switch 21 with appropriate force according to the correct operation steps, and the gasoline engine 2 can be started under the drive of mechanical force. In the case of stable power supply, electric starting is the preferred choice. The operator only needs to click on the control panel 8 to easily start the gasoline engine 2 and say goodbye to tedious manual operation. Of course, in the case of no access to power, the power supply device can also provide power for starting. In this embodiment, a storage battery 9 is also arranged on the inner side of the external support 1, and the storage battery is electrically connected with the gasoline engine 2, the vacuum pump 7 and the control panel. When the gasoline engine 2 is started, the engine will generate electricity and automatically charge the storage battery 9, realizing the recycling of electric energy. Since the storage battery 9 is closely connected with the vacuum pump 7 and the control panel 8, even without external power supply, the vacuum pump 7 can be started smoothly through the control panel 8 to ensure the normal operation of the equipment. Moreover, the storage battery 9 also has the function of external charging, which can be connected to the external power supply when the equipment is idle to store a lot of electric energy for subsequent use, so that the gasoline engine 2 can be directly started electrically, which is more convenient and efficient, greatly improving the outdoor adaptability and use efficiency of the equipment.

[0025] The utility model discloses a specific beneficial effect: the water diversion pump group of vacuum pump passes through the water diversion button on the control panel control vacuum pump work, motor, air pump pipe and so on parts cooperation, can quickly draw out the air of water diversion mouth place and form vacuum and realize water diversion, and the process automation and efficiency of comparing hand pressure mechanical type vacuum pump rely on manpower repeatedly press operation are higher, only need to press the corresponding button just can complete operation, such as starting gasoline engine, starting vacuum pump water diversion etc.

[0026] The above is only the embodiment of the utility model, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, a number of modifications and improvements can also be made, which should also be considered as the protection scope of the utility model, and these will not affect the effect and practicability of the utility model.
