Description

Technical Field

[0001] The utility model relates to the technical field of environmental pollution restoration and management, and in particular to an intelligent device for in-situ restoration of contaminated groundwater. Background Art

[0002] Groundwater is a precious freshwater resource for mankind. However, with the continuous development of the social industrialization process, wastewater discharge, industrial waste, agricultural irrigation, landfill leakage, damage to petrochemical raw material transportation pipelines and storage tanks, etc. may cause groundwater pollution, making the already tense water shortage problem more serious. It also poses serious threats and challenges to human health, food safety, drinking water safety, regional ecological environment, economic and social sustainable development and even social stability. Groundwater remediation has become an environmental issue that has attracted much attention from the public and society.

[0003] At present, existing technologies often extract groundwater at the same depth, but the degree of pollution of water at different depths is inconsistent, resulting in incomplete purification; and the purified water is often only discharged on the surface. If the water evaporates after being exposed to the sun in summer, the moisture content in the underground soil will decrease. Long-term extraction of groundwater may cause surface collapse, resulting in safety accidents and property losses. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent device for in-situ remediation of contaminated groundwater to solve the problems raised in the above-mentioned background technology.

[0016] Technical effects and advantages of the utility model:

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-Figure 4 An intelligent device for in-situ remediation of contaminated groundwater as shown in the figure comprises:

[0025] A water pumping pipe 1 has a limit plate 14 welded at its bottom end, and a connecting pipe 6 is welded at a position of the outer wall near the top, and the connecting pipe 6 is used to transport groundwater extracted from the ground. A limit ring 13 is welded slightly below the connecting pipe 6, and two electric slip rings 3 arranged up and down are slidably installed below the limit ring 13. The limit plate 14 and the limit ring 13 are used to limit the movement of the electric slip ring 3, and a plurality of water absorption holes 101 are opened on the outer wall of the water pumping pipe 1 between the limit plate 14 and the limit ring 13, and the water absorption holes 101 are used to absorb groundwater.

[0026] The fixed plate 2 has a slide rail 201 disposed on the left and right sides of its right side wall.

[0027] See also Figure 1 and Figure 3 An electric slider 4 is slidably installed in the slide rail 201. The electric slider 4 can move up and down along the slide rail 201. The right side wall of the electric slider 4 is fixedly connected to the left outer wall of the slip ring 3 by bolts. When the electric slider 4 moves, the slip ring 3 can be driven to move.

[0028] See also Figure 2 The caliber of the slip ring 3 is slightly larger than the caliber of the water pumping pipe 1. The slip ring 3 is sleeved on the outer wall surface of the water pumping pipe 1, and the inner wall of the slip ring 3 is tightly fitted with the outer wall of the water pumping pipe 1. The slip ring 3 can slide up and down along the outer wall of the water pumping pipe 1.

[0029] Furthermore, when the slip ring 3 moves to the designated position and stops, the height of the slip ring 3 can cover the corresponding water absorption hole 101, closing the water absorption hole 101, and the closed section cannot continue to absorb groundwater. If deep groundwater needs to be extracted, the electric slider 4 is controlled to move the slip ring 3, and the two slip rings 3 are moved upward along the pumping pipe 1. If surface groundwater needs to be extracted, the two slip rings 3 are moved downward along the pumping pipe 1. If the middle groundwater needs to be extracted, the two slip rings 3 are moved to the top and bottom of the pumping pipe 1 respectively.

[0030] return Figure 1The outlet end of the connecting pipe 6 is fixedly connected to the pump 5 by bolts, and an L-shaped water pipe 7 is fixedly installed on the top of the pump 5 by bolts, and the outlet end of the L-shaped water pipe 7 is connected to the filter pool 8. After determining the depth of groundwater to be extracted, the pump 5 is turned on, and the groundwater is extracted through the pumping pipe 1. The extracted groundwater enters the pump 5 through the connecting pipe 6, and then flows into the filter pool 8 through the L-shaped water pipe 7 at the top of the pump 5 for water purification.

[0031] Furthermore, a feeding port 9 is welded on the top wall of the filter tank 8, and the feeding port 9 is used to feed materials that can purify water sources, such as quartz sand, anthracite, activated carbon, fiber balls, etc.

[0032] Furthermore, an outlet pipe 10 is welded to the right side wall of the filter tank 8, and a control valve 16 is fixedly installed on the outlet pipe 10. The control valve 16 is used to control the discharge of groundwater in the filter tank 8, and the outlet end of the outlet pipe 10 is fixedly connected to a booster pump 11, and the outlet end of the booster pump 11 is fixedly connected to a drain pipe 12. The purified groundwater passes through the outlet pipe 10 and is pressurized by the booster pump 11 and flows into the drain pipe 12.

[0033] Furthermore, the electric slider 4, the water pump 5, and the booster pump 11 are all electrically connected to the control console 15, and the control console 15 controls the operation of the above-mentioned devices.

[0034] See also Figure 4 A spray port 1201 is provided on the outer wall of the drainage pipe 12 located underground. The purified groundwater is pressurized by the booster pump 11, passes through the drainage pipe 12, and is then sprayed out through the spray port 1201 to provide moisture for the underground soil and maintain humidity.

[0035] Working principle: When the utility model is used, the electric slider 4 slides up and down along the fixed plate 2 by operating the control console 15, thereby driving the slip ring 3 to move up and down along the surface of the pumping pipe 1. After the slip ring 3 is moved to the specified position, the control console 15 is operated to turn on the pump 5 to extract groundwater in the target area. The extracted groundwater enters the filter tank 8 through the L-shaped water pipe 7 and begins to be purified. After the purification is completed, the groundwater is pressurized by the booster pump 11 and sprayed out through the spray port 1201 on the drain pipe 12 and returns to the underground.
