Problems solved by technology

[0002] In hydrogeological exploration work, pumping test is an important means to obtain hydrogeological parameters and study the relationship between groundwater replenishment, diameter and drainage, and can provide basic parameters for water-rich division and groundwater resource quantity technology. However, the existing hydrogeological drilling layer pumping The water stop device and water stop device do not have any adjustment function, and cannot reduce the water pressure, and the pipeline may be damaged. There are even some water stop devices and water stop device structures that are pumped in layers by hydrogeological drilling. It is not stable enough, and there are certain safety hazards in use, so there is an urgent need for a water stopper for hydrogeological drilling layered pumping to solve the existing problems, so that users can use it

Embodiment 1

[0040] Such as Figure 1-Figure 7 shown

[0041]This embodiment provides a water stopper for water resources and hydrogeological pumping, including a water suction pipe 1, a backflow prevention device arranged at the lower end of the water suction pipe 1, and an intermediate pipe detachably connected to the upper end of the water suction pipe 1 2 and the water stop section 4 detachably connected with the intermediate pipe 2; The air bag 3 on the surface, the inflatable tube 30 and the air pump 31 that one end communicates with the air bag 3; The plate 19 is located on the upper part of the water pumping hole 10, the rib plate 19 is provided with a water hole 13, and the middle position of the rib plate 19 is provided with a water stop rod hole 100, and the water stop rod hole 100 is a through hole; The backflow prevention device includes a water stop rod 12 slidingly connected to the water stop rod hole 100 in the middle of the rib plate 19, a gasket 11 arranged on the lower...

Embodiment 2

[0053] This embodiment is basically the same as Embodiment 1, the difference is:

[0054] The pressure relief gasket 17 and the gasket 11 are rubber gaskets. The main products of rubber sealing gaskets are: silicone pads, nitrile rubber pads, fluorine rubber pads, and other rubber pads. Silicone rubber has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70°C to +260°C, is resistant to ozone and weather aging, and is suitable for sealing gaskets in thermal machinery. It is non-toxic and can be used to make heat insulation, insulation products and medical rubber products. At the same time, it has excellent properties such as waterproof, flame retardant, high temperature resistance, electrical conductivity, wear resistance, and oil resistance. It is widely used in various industries such as machinery, electronics, and plumbing. The silicone mats produced by the company meet EU environmental protection standards and EU food-...

Abstract

The invention relates to a water stop for water resources and hydrogeology water pumping, and a use method. The water stop for water resources and hydrogeology water pumping comprises a water suctionpipe, a backflow prevention device arranged at the lower end in the water suction pipe, a pressure relief device arranged at the lower part of the side wall of the water suction pipe, a middle pipe indismountable connection with the upper end of the water suction pipe, and a water stopping segment in dismountable connection with the middle pipe, wherein the water stopping segment comprises a water stopping segment body in dismountable connection with the middle pipe, an air bag arranged on the outer surface of the water stopping segment body, a charging pipe of which one end communicates withthe air bag, and an air pump. The water stop disclosed by the invention has the beneficial effects that the air bag is arranged, so that a water layer which does not need water pumping can be plugged; and the pressure relief device is arranged, so that overpressure water can be subjected to pressure relief, damage of the overpressure water to pipelines can be avoided, and the service life of thewater stop can be prolonged.
