Description

Technical Field

[0001] The utility model relates to the technical field of groundwater extraction, and more specifically, to a quantitative water extraction device for shallow groundwater. Background Art

[0002] Shallow groundwater extraction devices refer to equipment that extracts water resources from shallow underground water sources. They are usually used for water supply, agricultural irrigation, industrial water use and some specific environmental projects. Existing water extraction devices include bucket-type water extraction devices and pump-type water extraction devices. Among them, bucket-type water extraction devices are widely used in resource-poor areas because of their low cost, simple use, no need for external energy, wide applicability and reliability.

[0003] The amount of water drawn by a traditional water bucket at a time is difficult to control and cannot be set according to demand. This results in excessive water being drawn during the drawing process, which is likely to waste water resources and is not conducive to sustainable water resource management. If too little water is drawn, repeated drawing is required, which takes a long time and reduces work efficiency. Prior art patent No. CN221649943U discloses a quantitative water drawing device for shallow groundwater. It can achieve on-demand water drawing through the cooperation of hollow tubes, circular tubes and other components. However, the above-mentioned implementation process requires human operation. Whenever the water drawing amount changes, human adjustments are required, which is relatively time-consuming and labor-intensive. Therefore, it is an urgent problem for those skilled in the art to be able to automatically adjust the water drawing amount according to demand and achieve quantitative water drawing.

The piston is sealed to the inner wall of the water extraction pipe.

[0006] Furthermore, the driving component is an electric telescopic rod, the upper end of the electric telescopic rod is fixedly connected to the lower surface of the top plate, and the lower end is fixedly connected to the piston. When the electric telescopic rod is in the shortest state, the lower end of the electric telescopic rod is located in the water intake pipe.

[0007] Furthermore, the driving assembly includes a pressure rod, a pressure plate and an electric telescopic rod. The pressure plate is horizontally arranged above the water intake pipe. The lower end of the pressure rod extends into the water intake pipe and is fixedly connected to the piston. The upper end of the pressure rod is fixedly connected to the bottom surface of the pressure plate. The electric telescopic rod is fixed between the top plate and the pressure plate.

[0008] Furthermore, the water intake pipes are distributed in a circular array and close to the inner arm of the barrel body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The quantitative water extraction device for shallow groundwater in the utility model extracts water by driving the piston up and down through a driving assembly.

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the quantitative water extraction device for shallow groundwater in this embodiment includes a water extraction bucket, a pull rope 4, a water extraction pipe 5 and a water extraction mechanism. The water extraction bucket includes a barrel body 1 and a top plate 2 and a bottom plate 3 sealed and fixed at the upper and lower ends of the barrel body 1. The pull rope 4 is connected to the upper surface of the top plate 2. Two water extraction pipes 5 are fixed vertically and horizontally symmetrically in the water extraction bucket, and the lower ends of the water extraction pipes 5 pass through the bottom plate 3. The bottom surface of the water extraction pipes 5 is provided with a water inlet pipe 6, and the upper end of the water extraction pipe 5 is open. In some other embodiments, the number of water extraction pipes 5 can also be set to multiple. When multiple water extraction pipes 5 are provided in the water extraction bucket, the multiple water extraction pipes 5 are distributed in the form of a circular array. The water extraction mechanism includes a piston 7 provided in the water extraction pipe 5 and a drive assembly that drives the piston 7 to move up and down. The piston 7 is sealed and connected to the inner wall of the water extraction pipe 5.

[0026] In this embodiment, the driving assembly is an electric telescopic rod 8. The upper end of the electric telescopic rod 8 is fixedly connected to the lower surface of the top plate 2, and the lower end of the electric telescopic rod 8 is fixedly connected to the upper surface of the piston 7. When the electric telescopic rod 8 is at its shortest position, the lower end of the electric telescopic rod 8 is located within the water intake pipe 5. The extension and contraction of the electric telescopic rod 8 drives the rise and fall of the piston 7, thereby discharging water. The height to which the piston 7 rises determines the amount of water withdrawn.

[0027] In this embodiment, sealant is applied between the water intake pipe 5 and the base plate 3, creating a sealed structure inside the water intake bucket. This prevents water from entering the bucket and potentially affecting the proper operation and service life of the electric telescopic rod 8. A baffle is positioned inside the upper end of the water intake pipe 5. The baffle's outer diameter matches the water intake pipe 5 and is sealed against the inner wall of the pipe 5. The baffle defines a through-hole for the electric telescopic rod 8 to pass through, and the electric telescopic rod 8 and the baffle are also sealed against each other. A piston 7 is preferably slidably and sealingly connected to the inner wall of the water intake pipe 5. The piston 7 comprises a stopper plate and a rubber sealing ring secured to the edge of the stopper plate.

[0028] In this embodiment, the water pipes are distributed in a circular array and are close to the inner arm of the barrel body 1. The barrel body 1 is provided with a viewing window 11 corresponding to the water intake pipe 5. The water intake pipe 5 is made of a transparent material, and a scale line 12 is provided on the side of the water intake pipe 5 close to the viewing window 11. The water level in the water intake pipe 5 can be observed through the viewing window 11. Specifically, the viewing window 11 can be made of acrylic material, and the water intake pipe 5 can be made of polypropylene or polycarbonate.

[0029] In this embodiment, a filter screen 13 is provided on the outside of the water inlet pipe 6 to filter the water entering the water intake pipe 5. The filter screen 13 is detachably connected to the water intake pipe 5. Specifically, a transition pipe 17 is provided at the lower end of the water intake pipe 5. The outer diameter of the transition pipe 17 is smaller than that of the water intake pipe 5. The transition pipe 17 is connected to the interior of the water intake pipe 5 and is integrally arranged. The water inlet pipe 6 is disposed at the lower end of the transition pipe 17. The filter screen 13 is a cylindrical structure with an open top. The filter screen 13 is provided on the outside of the water inlet pipe 6 and is threadedly connected to the transition pipe 17. Preferably, the water inlet pipe 6 is provided with a one-way valve 14. A drain pipe 15 and a drain valve 16 are provided on the sidewall of the lower end of the water intake pipe 5, with the drain pipe 15 located outside the filter screen 13. When drawing water, the drain valve 16 is closed, allowing groundwater to enter the water intake pipe 5 from the water inlet pipe 6. When draining water, the drain valve 16 is opened, and the water in the water intake pipe 5 flows out through the drain pipe 15.

[0030] The quantitative water extraction device for shallow groundwater in this embodiment also includes a controller, which is installed at the top of the groundwater well for easy operation by the operator. The controller is connected to the electric telescopic rod 8, thereby controlling the lifting and travel of the electric telescopic rod 8. Preferably, a counterweight is also provided at the bottom of the water sampling bucket to ensure that the sampling barrel remains in a vertical position during the water extraction process.

[0031] The working principle of the quantitative water extraction device for shallow groundwater in this embodiment is:

[0032] Before sampling, first open the drain valve 16. The controller controls the extension of the electric telescopic rod 8, moving the piston 7 to the bottom of the water intake pipe 5. The drain valve 16 is closed, and the water bucket is lowered into the groundwater well via the pull rope 4. The controller controls the contraction of the electric telescopic rod 8, causing the piston 7 to move upward. Groundwater is then drawn into the water intake pipe 5 through the water inlet pipe 6. The controller controls the length of contraction of the electric telescopic rod 8, thereby controlling the distance the piston 7 moves upward. This determines the amount of water drawn, achieving quantitative water extraction. Simultaneously drawing water from both water intake pipes 5 effectively reduces water sampling errors. After drawing water, the pull rope 4 is used to lift the water bucket above the groundwater well. The drain valve 16 is opened to remove the water sample from the water intake pipe 5.

[0033] Example 2:

[0034] like Figure 4 As shown, the quantitative water intake device for shallow groundwater in this embodiment differs from the first embodiment in the drive assembly. The drive assembly in this embodiment includes a pressure rod 9, a pressure plate 10, and an electrically operated telescopic rod 8. The pressure plate 10 is horizontally arranged above the water intake pipe 5. The lower end of the pressure rod 9 extends into the water intake pipe 5 and is fixedly connected to the piston 7. The upper end of the pressure rod 9 is fixedly connected to the bottom surface of the pressure plate 10. The electrically operated telescopic rod 8 is fixed between the top plate 2 and the pressure plate 10.

[0035] In this embodiment, only one electric telescopic rod 8 is required regardless of the number of water intake pipes 5. However, in the first embodiment, the same number of electric telescopic rods 8 as the number of water intake pipes 5 are required. Compared to the first embodiment, the quantitative water intake device for shallow groundwater in this embodiment can reduce costs and weight.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
