Towerless automatic water-supply vacuum tube well

Abstract

The invention discloses a towerless automatic water-supply vacuum tube well. The towerless automatic water-supply vacuum tube well comprises a drill hole, a well casing is arranged in the center of the drill hole, the well casing is composed of a water taking section and a pump mounting section, and the pump mounting section is internally provided with a water pumping device and a water supply pipe from bottom to top in sequence. The top of the well casing is provided with a flange, and a seal cover is arranged on the top of the flange; a pressure sensor is arranged on the water supply pipe; amaintenance chamber is arranged above the drill hole, and a cover plate is arranged on the top of the maintenance chamber. The structure is simple, the manufacturing cost is low, the structure that awell mouth is sealed is adopted, noxious substances and contaminants are effectively prevented from falling into a well, and potential safety hazards of drinking water are eliminated. Through the cooperation of the well casing and the water pumping device, the water taking section in the well is hermetically isolated from the pump mounting section, vacuum is formed in the water taking section, and the water yield of the tube well is increased; air in the well casing is compressed by water in the pump mounting section to form elastic pressure water, it is ensured that the water supply pressureand the water supply amount are stable, and the towerless automatic water-supply vacuum tube well has the advantages that the water is stably supplied, the water is safe, and the well occupies littlespace.

Description

technical field [0001] The invention belongs to the technical field of drilling, and relates to a water well, in particular to a tower-less automatic water supply vacuum tube well. Background technique [0002] The tube well is a water intake structure with a small diameter and a large well depth to draw deep or shallow groundwater. It can be vertical, oblique and combined in different directions, but it is generally vertical and can be used for domestic water intake and irrigation. [0003] At present, the conventional tube wells are basically open wells, which generally use pumping equipment to pump groundwater to a reservoir above the ground, a water tower or an electronically controlled towerless water supply system for water supply, and open wells are prone to fall into dirt Or pollutants such as rats and cockroaches threaten the safety of drinking water. Ground water supply facilities take up space, and the water level in the well naturally drops when the conventional...

Ground water supply facilities take up space, and the water level in the well naturally drops when the conventional well is pumped. Small
