DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The purpose of the present invention is to provide a groundwater extraction device which automatically adopts corresponding extraction methods for groundwater at different depths, has good extraction effect and improves work efficiency.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-3As shown, this embodiment provides a groundwater extraction device, including a water suction pipe 1, a vacuum pump 15, an air suction pipe 25, an air suction component, a water tank 2, a filter box 4, a purification component and a controller, wherein the filter box 4 is provided with a filter component, and the water tank 2 is arranged on the ground surface. Specifically, this embodiment also includes a second bracket 27, and the second bracket 27 is arranged on the ground surface, and the second bracket 27 is arranged above the wellhead, and the water tank 2 is arranged on the second bracket 27. The lower end of the water pumping pipe 1 is connected to the groundwater layer, and the upper end of the water pumping pipe 1 extends into the water tank 2 and extends to the upper part of the water tank 2. A liquid level sensor 13 is arranged on one side of the lower end of the water pumping pipe 1. The upper end of the air pumping pipe 25 is connected to the air pumping assembly, and the lower end of the air pumping pipe 25 is connected to one side of the middle part of the water pumping pipe 1. A waterproof and breathable assembly is installed on the pipe mouth of the lower end of the air pumping pipe 25. By setting the waterproof and breathable assembly, the gas in the water pumping pipe 1 can enter the air pumping pipe 25, and at the same time, the water in the water pumping pipe 1 is prevented from entering the air pumping pipe 25, so that the air pumping assembly can extract the gas in the water pumping pipe 1 through the air pumping pipe 25; the upper part of the water tank 2 is provided with an air inlet 16 and an air outlet 1 4, a vacuum pump 15 is connected to the air outlet 14, a first valve 17 is arranged on the air inlet 16, the lower end of the water tank 2 is connected to the upper end of the filter box 4 through the first connecting pipe 3, the lower end of the filter box 4 is connected to one end of the purification component through the second connecting pipe 5, the other end of the purification component is connected to the water outlet pipe 9, the first connecting pipe 3 is provided with a first water pump 10, the second connecting pipe 5 is provided with a second water pump 11, the water outlet pipe 9 is provided with a third water pump 12, the vacuum pump 15, the air extraction component, the liquid level sensor 13, the first valve 17, the first water pump 10, the second water pump 11 and the third water pump 12 are all connected to the controller.

[0024] When extracting groundwater, the controller controls the first valve 17, the first water pump 10, the second water pump 11 and the third water pump 12 to close, and the liquid level sensor 13 transmits a signal to the controller. A liquid level value is set in the controller. In this specific embodiment, the set liquid level value is 1m. When the detected liquid level value is higher than the set liquid level value, it means that the water level is high at this time. The controller only controls the vacuum pump 15 to turn on, which can meet the extraction requirements. When the vacuum pump 15 is working, the gas in the water tank 2 and the suction pipe 25 is discharged through the outlet 14, and the gas in the water tank 2 is discharged. When the air pressure in the water tank 2 is lower than the groundwater pressure, the groundwater enters the water tank 2 through the pumping pipe 1; when the detected liquid level value is lower than the set liquid level value, it means that the water level is low at this time, and only turning on the vacuum pump 15 cannot meet the extraction requirements. The controller controls the vacuum pump 15 and the air extraction component to start at the same time to extract the gas in the air extraction pipe 25 and the water tank 2 to solve the problem of poor extraction effect when the water level is low. By automatically taking corresponding extraction methods for groundwater at different depths, the extraction effect is good and the work efficiency is improved. When it is necessary to take and purify the groundwater in the water tank 2, turn off the vacuum pump 15 and the air extraction component, turn on the first valve 17, the first water pump 10, the second water pump 11 and the third water pump 12, and the groundwater in the water tank 2 is filtered and purified by the filtering component and the purification component, and discharged through the outlet pipe 9, which can be used for drinking by users.
