[0007] Furthermore, the limiting component includes two L-shaped plates, which are respectively fixed to the outer walls of the two sides of the housing by bolts. Each of the two L-shaped plates is movably connected to a lead screw, and one end of the lead screw is movably connected to a pressure block.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1-6 A hydrogeological pumping test device includes a base plate 6. A cylinder 1 is fixed to the upper surface of the base plate 6 by bolts. A second cover plate 8 is installed on the top of the cylinder 1 by a limiting assembly. The limiting assembly includes two L-shaped plates 12, which are respectively fixed to the outer walls of the two sides of the housing 4 by bolts. A screw rod 11 is threaded to each of the two L-shaped plates 12. A pressure block 10 is threaded to one end of the screw rod 11 and contacts the cross plate of the L-shaped plate 12. An inclined surface is provided on one side of the pressure block 10 and contacts the second cover plate 8. The limiting assembly fixes the second cover plate 8 to the top of the cylinder 1 by the screw rod 11, the pressure block 10, etc., which can prevent debris from falling into the cylinder 1 and affecting the pumping test. By rotating the screw rod 11, the inclined surface of the pressure block 10 can be separated from or contacted with the second cover plate 8, thereby facilitating the disassembly and assembly of the second cover plate 8.

[0022] In this invention, two fixing rings 13 are bolted to the inner circumference of the cylinder 1. Each fixing ring 13 has a drain plate 9. A first connecting rod 14 is bolted to the upper drain plate 9, and a second connecting rod 17 is bolted to the lower drain plate 9. The first connecting rod 14 and the second connecting rod 17 are connected by a pin assembly. After water enters the cylinder 1, it first passes through the upper drain plate 9, which performs preliminary filtration of larger impurities in the water. The lower drain plate 9 then performs secondary filtration. After these two filtrations, the water... As the water continues to flow downwards, the pin assembly includes a slot 18. The slot 18 is located at the bottom end of the first connecting rod 14, which passes through the drain plate 9 connected to it. A fixing bracket 16 is welded to one side of the second connecting rod 17. A plug rod 15 is fixed to one side of the fixing bracket 16 by bolts, and the plug rod 15 is inserted into the slot 18 at the corresponding position. Pulling the first connecting rod 14 upwards separates the two drain plates 9 from the fixing ring 13 until they are completely removed from the cylinder 1, thus facilitating the cleaning of the drain plates 9 by the staff. By pulling the plug rod 15, it is separated from the slot 18, thus separating the two drain plates 9.

[0023] Specifically, a housing 4 is bolted to the upper surface of the base plate 6. Multiple limiting rings 23 are bolted to the bottom inner wall of the housing 4. A water bucket 19 is placed inside each of the limiting rings 23. A support plate 29 is bolted to the inner wall of the water bucket 19. A sliding cylinder 28 is welded to the bottom of the support plate 29. A sliding rod 27 is slidably connected to the bottom of the sliding cylinder 28. A pressure plate 25 is bolted to the bottom end of the sliding rod 27. A spring 31 is installed inside the sliding cylinder 28, and both ends of the spring 31 are fixed to the sliding rod 27 and the sliding cylinder 28, respectively. A slot 30 is opened at the bottom of the water bucket 19, and the pressure plate 25 blocks the slot 30. A sealing gasket is fixed on the pressure plate 25, sealingly connecting to the slot 30. A second connecting pipe 26 is connected and fixed inside the slot 30, and the bottom ends of multiple second connecting pipes 26 pass through the slot 30. The bottom plate 6 is connected and fixed with a first connecting pipe 24. The upper surface of the bottom plate 6 is provided with a water pumping assembly that is connected to the first connecting pipe 24 and the cylinder 1. The water pumping assembly includes a water pump 5, which is fixed to the upper surface of the bottom plate 6 by bolts. The water inlet of the water pump 5 is connected and fixed to the cylinder 1, and the water outlet of the water pump 5 is connected and fixed to the first connecting pipe 24. After being filtered twice, the water continues to flow downward from the cylinder 1 into the first connecting pipe 24 connected to the water outlet of the water pump 5, and then flows into each water bucket 19 through the second connecting pipe 26. That is, in the water bucket 19, the water in the second connecting pipe 26 exerts pressure on the pressure plate 25, causing the slide rod 27 to slide in the slide cylinder 28 and compress the spring 31. At this time, the pressure plate 25 moves upward and loses its obstruction to the slot 30, and the water in the second connecting pipe 26 enters the water bucket 19.

[0024] It should be noted that the top of the shell 4 is rotatably connected to the first cover plate 3. The shell 4 and the first cover plate 3 are fixed by a detachable latch 2, which makes it easy to open when the water bucket 19 needs to be replaced or maintained. The top of the water bucket 19 is threadedly connected to a sealing cover 20. The sealing cover 20 has an exhaust hole 21, which allows the gas inside the water bucket 19 to be discharged. The top of the sealing cover 20 is fixed with two top blocks 22 by bolts, and the top blocks 22 are in contact with the first cover plate 3. When the first cover plate 3 is closed, the top blocks 22 are pressed by the first cover plate 3, which can further stabilize the position of the water bucket 19 within the limiting ring 23. A water inlet is opened on the top of one side of the cylinder 1. A water inlet pipe 7 is fixedly connected to the water inlet. The water inlet pipe 7 is connected to the external pipe and connected to the external water source that needs to be sampled. The water pump 5 is started, so that the water in the external water source enters the cylinder 1 through the water inlet pipe 7.

[0025] The working principle of this embodiment is as follows: When water needs to be pumped, the water inlet pipe 7 is connected to the external water source to be sampled through the external pipe. The water pump 5 is started, so that the water in the external water source enters the cylinder 1 through the water inlet pipe 7. After the water enters the cylinder 1, it will first pass through the upper strainer 9. The strainer 9 can play a preliminary filtering role for larger impurities in the water. The lower strainer 9 performs secondary filtration on the water. After two filtrations, the water continues to flow downward and flows from the cylinder 1 into the first connecting pipe 24 connected to the outlet of the water pump 5. Then, it flows into each water bucket 19 through the second connecting pipe 26. That is, in the water bucket 19, the water in the second connecting pipe 26 exerts pressure on the pressure plate 25, so that the slide rod 27 slides in the slide cylinder 28 and compresses the spring 31. At this time, the pressure plate 25 moves upward and no longer blocks the slot 30, and the water in the second connecting pipe 26 enters the water bucket 19.

[0026] The sealing cap 20 at the top of the bucket 19 prevents water from splashing out, while the vent 21 balances the air pressure inside and outside the bucket, facilitating the inflow of water. The top block 22 on the sealing cap 20 contacts the first cover plate 3. When the first cover plate 3 is closed, the top block 22 is pressed by the first cover plate 3, which can further stabilize the position of the bucket 19 within the limiting ring 23.

[0027] The first cover plate 3 is fixed to the housing 4 by a detachable latch 2, which makes it easy to open when the water tank 19 needs to be replaced or maintained. The limiting component fixes the second cover plate 8 to the top of the cylinder 1 by means of the screw 11, the pressure block 10, etc., which can prevent debris from falling into the cylinder 1 and affecting the pumping test. By rotating the screw 11, the inclined surface of the pressure block 10 is separated from or in contact with the second cover plate 8, which makes it easy to disassemble and assemble the second cover plate 8.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
