Furthermore, an air valve cap is arranged on the air valve, the air valve cap is in threaded connection with the air valve, and the air tightness can be enhanced by additionally arranging the air valve cap.

Further, a sealing ring is arranged on the bottom surface of the tank cover.

Further, the valve is a bidirectional ball valve.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses utilize the diversion jar to lead water, utilize the water pump to produce the negative pressure and can make the suction pipe continuously absorb water to realize the continuous operation of device, utilize the fluctuation of rubber membrane can the holistic gas tightness of audio-visual observation device, and use the inflating valve to be used for realizing disappointing of device, detachable cover makes things convenient for the water injection of device, and simple structure overhauls conveniently; but also can close the valve simultaneously thereby realize prestoring partial diversion in the diversion jar, can use in the multiple place that does not have tap or inconvenient water intaking, use in a flexible way, do not worry moreover that the diversion spills, convenient removal.

Drawings

Fig. 1 is the utility model relates to a water pump is from water sucking device's structural schematic.

As shown in the figure: 1. the water diversion tank comprises a water diversion tank body 2, a water outlet pipe 3, a water suction pipe 4, a tank cover 5, a rubber film 6, an inflating valve 7, a valve 8, an inflating valve cap 9 and a sealing ring.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example, see figure 1: the utility model discloses, 1, including water diversion jar 1, outlet pipe 2 and suction tube 3, suction tube 3 installs in the inside of water diversion jar 1 and suction tube 3 stretches out the bottom of water diversion jar 1, outlet pipe 2 runs through the bottom of water diversion jar 1 and communicates with jar body airtight, water diversion jar 1 is the top surface and is equipped with the open-ended jar body, the upper portion jar body cloth of water diversion jar 1 has the screw thread, the top surface opening part of water diversion jar 1 is equipped with cover 4, cover 4 with water diversion jar 1 passes through threaded connection, the center of cover 4 is equipped with circular fretwork, the fretwork department of cover 4 is airtight sets up rubber membrane 5, the central airtight setting inflating valve 6 of rubber membrane 5, inflating valve 6 airtight connection rubber membrane 5 just communicates water diversion jar 1; and valves 7 are arranged at the tail ends of the water outlet pipes 2 and one ends of the water suction pipes 3, which are positioned in the water diversion tanks 1, and the valves 7 are hermetically communicated with the water outlet pipes 2 and the water diversion tanks 1.

The valve 6 is an American valve, a valve cap 8 is arranged on the valve 6, the valve cap 8 is in threaded connection with the valve 6, a sealing ring 9 is arranged on the bottom surface of the tank cover 4, and the valve 7 is a bidirectional ball valve.

When the water storage tank is used specifically, water is stored in the water diversion tank 1 in advance, the tank cover 4 is closed, the water suction pipe 3 and the valve 7 on the water outlet pipe 2 are closed, leakage is avoided, and the water storage tank can be moved to a designated place. Then the valve 7 of the water outlet pipe 2 is communicated with a water pump, the water suction pipe 3 extends into the water area, and the valve 7 of the water suction pipe 3 is opened; before starting the water pump, the valve 6 and the valve 7 of the water outlet pipe 2 are opened to realize water diversion and injection of the water pump; after the water pump is started, water in the water diversion tank 1 is pumped away, a certain vacuum degree can be formed in the water diversion tank 1, and therefore the water needing to be pumped up is guided into the water diversion tank 1 through the water suction pipe 3.
