Description

Technical Field

[0001] This invention relates to the field of well pumping technology, specifically to a well pumping device for foundation pit dewatering support engineering. Background Technology

[0002] The well pumping device for foundation pit dewatering support engineering is a device used to extract water from the inside of the well in foundation pit dewatering support engineering.

[0003] Based on the above, the inventors have discovered that: Currently, there are many well pumping devices for foundation pit dewatering and support engineering on the market. However, in general, well pumping devices for foundation pit dewatering and support engineering involve workers fixing the pipe to the output end of the water pump and then inserting one end of the pipe into the well for pumping. However, the inside of the well contains silt mixed with the water source, causing the silt to enter the pipe along with the water source, which can easily lead to blockage. This severely interferes with the normal extraction of water from the well and reduces the practicality of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a well pumping device for foundation pit dewatering and support engineering, aiming to achieve a more practical value. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The present invention provides a well pumping device for foundation pit dewatering support engineering, comprising a water intake column, a groove plate matched to the inner wall of the water intake column, a filter mechanism at the bottom end of the water intake column, and a pumping mechanism at the top end of the groove plate. The filtration mechanism includes: A screen is set at the bottom of the water-guiding column and below the trough plate. An activated carbon filter element is provided at the top of the screen. The outer wall of the activated carbon filter element is matched with the inner wall of the water-guiding column. The activated carbon filter element is set below the trough plate.

[0005] As a preferred embodiment of the present invention, the outer wall of the water-guiding column is fitted with a protective sleeve, and the inner wall of the protective sleeve is matched with the outer wall of the screen.

[0006] As a preferred embodiment of the present invention, connecting plates are fixed on both sides of the trough plate, and blocks are fixed at the bottom of the two connecting plates. The outer walls of the two blocks are matched with the inner walls of the water-diverting column.

[0007] As a preferred embodiment of the present invention, the outer wall of the trough plate is fixed with two ring plates, and the inner walls of the two ring plates are threaded with studs, the bottom ends of the two studs being threaded with the inner wall of the water-guiding column.

[0008] As a preferred embodiment of the present invention, the top of the screen is fixed with two connecting blocks, the outer walls of the two connecting blocks are matched with the inner walls of the water-guiding column, the inner walls of the two connecting blocks are penetrated by connecting rods, and the outer walls of the two connecting rods are matched with the inner walls of the water-guiding column.

[0009] As a preferred embodiment of the present invention, the top of the activated carbon filter element is fixed with four support blocks, the inner walls of the four support blocks are all fitted with screws, the bottom ends of the four screws are all fixed to the top of the activated carbon filter element, the outer walls of the four screws are all threaded with threaded rings, and the four threaded rings are all disposed at the top of the support blocks.

[0010] As a preferred embodiment of the present invention, each of the four support blocks is provided with a cover plate at its top, and the inner wall of each of the four cover plates is matched with the outer wall of the screw ring.

[0011] As a preferred embodiment of the present invention, the pumping mechanism includes: The box body is located above the trough plate. A water pump is fixed to the bottom of the inner wall of the box body. A check valve is fixed to the output end of the water pump. A connecting pipe is fixed to the inner wall of the check valve. The bottom end of the connecting pipe is fixed to the inner wall of the trough plate.

[0012] As a preferred embodiment of the present invention, the top of the protective sleeve is fixed with four groove blocks, the inner walls of the four groove blocks are matched with cylinders, and the bottom ends of the four cylinders are fixed to the top of the water-guiding column.

[0013] The beneficial effects of this invention are: 1. This solution involves sliding the activated carbon filter element along the inner wall of the water intake column, allowing its top end to fit against the bottom end of the support block. This, in turn, allows the outer wall of the screw to be fitted onto the inner wall of the support block. The inner wall of the screw ring is threaded onto the outer wall of the screw, thus securing the activated carbon filter element at the bottom of the support block. The inner wall of the cover plate matches the outer wall of the screw ring for protection of the screw's outer wall. The top end of the screen fits against the bottom end of the water intake column, allowing the connecting block fixed to the top of the screen to match the inner wall of the water intake column. Finally, the outer wall of the connecting rod is fitted onto one side of the water intake column, matching the outer wall of the connecting rod with the inner wall of the connecting block. This effectively filters and separates sediment when the water intake column pumps water from the well, preventing sediment from entering the connecting pipe and causing blockages. Therefore, it effectively improves the pumping performance of the device on the well.

[0014] 2. This solution uses a protective sleeve whose inner wall is fitted onto the outer wall of the water-guiding column. Simultaneously, the bottom of the inner wall of the protective sleeve matches the outer wall of the screen. This allows the grooved block fixed at the top of the protective sleeve to match the outer wall of the cylinder fixed at the top of the water-guiding column. This effectively improves the stability of the water-guiding column and screen inside the well, preventing structural disintegration due to impact from mud and sand. The outer wall of the grooved plate matches the inner wall of the water-guiding column, and the connecting plates fixed on both sides of the grooved plate align with the top of the water-guiding column, matching the outer wall of the block with the inner wall of the water-guiding column. A threaded connection is used between the outer wall of the stud and the inner wall of the ring plate until the bottom of the stud is threaded onto the inner wall of the water-guiding column. This ensures the grooved plate is securely installed on the inner wall of the water-guiding column, allowing operators to better control the water pump to draw water from inside the well into the housing via the water-guiding column.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: Figures 1-7 As shown, the present invention provides a well pumping device for foundation pit dewatering support engineering, including a water intake column 1, a groove plate 2 matched to the inner wall of the water intake column 1, a filter mechanism 3 at the bottom end of the water intake column 1, and a pumping mechanism 4 at the top end of the groove plate 2. Filter mechanism 3 includes: A screen 31 is located at the bottom of the water-guiding column 1, below the trough plate 2. An activated carbon filter element 32 is mounted at the top of the screen 31. The outer wall of the activated carbon filter element 32 matches the inner wall of the water-guiding column 1. Two connecting blocks 33 are fixed to the top of the screen 31. The outer walls of both connecting blocks 33 match the inner wall of the water-guiding column 1. Connecting rods 34 penetrate the inner walls of both connecting blocks 33. The outer walls of both connecting rods 34 match the inner wall of the water-guiding column 1. Four connecting rods 34 are fixed to the top of the activated carbon filter element 32. Each of the four support blocks 35 has a screw 36 fitted on its inner wall. The bottom end of each screw 36 is fixed to the top end of the activated carbon filter element 32. The outer wall of each screw 36 is threaded with a threaded ring 37. Each threaded ring 37 is located at the top end of each support block 35. Each top end of each support block 35 is provided with a cover plate 38. The inner wall of each cover plate 38 matches the outer wall of the threaded ring 37. This effectively filters and separates sediment when the water column 1 extracts water from the well, preventing sediment from entering the connecting pipe 44 and causing blockage. This effectively improves the pumping effect of the device on the well.

[0019] As attached Figure 1 , Figure 2 and Figure 7 As shown, a protective sleeve 5 is fitted over the outer wall of the water intake column 1. The inner wall of the protective sleeve 5 matches the outer wall of the screen 31. Four groove blocks 10 are fixed to the top of the protective sleeve 5. A cylinder 11 is fitted over the inner wall of each of the four groove blocks 10. The bottom of each of the four cylinders 11 is fixed to the top of the water intake column 1. By fitting the inner wall of the protective sleeve 5 over the outer wall of the water intake column 1, and simultaneously matching the bottom of the inner wall of the protective sleeve 5 with the outer wall of the screen 31, the groove blocks 10 fixed at the top of the protective sleeve 5 match the outer wall of the cylinders 11 fixed at the top of the water intake column 1. This effectively improves the stability of the water intake column 1 and the screen 31 inside the well, preventing the device structure from disintegrating due to collisions with mud and sand.

[0020] As attached Figure 1 and Figure 2As shown, connecting plates 6 are fixed on both sides of the trough plate 2, and blocks 7 are fixed at the bottom of the two connecting plates 6. The outer walls of the two blocks 7 are matched with the inner walls of the water-diverting column 1. Two ring plates 8 are fixed on the outer wall of the trough plate 2. The inner walls of the two ring plates 8 are threaded with studs 9. The bottom ends of the two studs 9 are threaded with the inner walls of the water-diverting column 1, which facilitates the reinforcement of the tightness of the fit between the outer wall of the trough plate 2 and the inner wall of the water-diverting column 1, and prevents the trough plate 2 from loosening and detaching inside the water-diverting column 1.

[0021] As attached Figure 1 and Figure 6 As shown, the pumping mechanism 4 includes: The housing 41 is located above the trough plate 2. A water pump 42 is fixed to the bottom of the inner wall of the housing 41. A check valve 43 is fixed to the output end of the water pump 42. A connecting pipe 44 is fixed to the inner wall of the check valve 43. The bottom end of the connecting pipe 44 is fixed to the inner wall of the trough plate 2, which facilitates the extraction of water from the well into the housing 41 for storage.

[0022] Working Principle: During use, the activated carbon filter element 32 slides along the inner wall of the water-guiding column 1, allowing its top end to fit against the bottom end of the support block 35. This allows the outer wall of the screw 36 to be fitted onto the inner wall of the support block 35. The inner wall of the screw ring 37 is threaded onto the outer wall of the screw 36, thus securing the activated carbon filter element 32 at the bottom of the support block 35. The inner wall of the cover plate 38 matches the outer wall of the screw ring 37 for protection of the screw 36. The top end of the screen 31 fits against the bottom end of the water-guiding column 1, allowing the connecting block 33 fixed to the top of the screen 31 to match the inner wall of the water-guiding column 1. The outer wall of the connecting rod 34 is fitted onto one side of the water-guiding column 1, allowing the outer wall of the connecting rod 34 to match the inner wall of the connecting block 33. This effectively filters and separates sediment when the water-guiding column 1 extracts water from the well, preventing sediment from entering the connecting pipe 44 and causing blockage. To improve the pumping effect of the device on the well, the inner wall of the protective sleeve 5 is fitted with the outer wall of the water intake column 1, and the bottom of the inner wall of the protective sleeve 5 is matched with the outer wall of the screen 31. The groove block 10 fixed at the top of the protective sleeve 5 is matched with the outer wall of the cylinder 11 fixed at the top of the water intake column 1. This effectively improves the stability of the water intake column 1 and the screen 31 inside the well and avoids the device structure from disintegration due to collision with mud and sand. The outer wall of the groove plate 2 is matched with the inner wall of the water intake column 1, and the connecting plates 6 fixed on both sides of the groove plate 2 are matched with the top of the water intake column 1. The outer wall of the block 7 is matched with the inner wall of the water intake column 1. The outer wall of the stud 9 is threaded through the inner wall of the ring plate 8 until the bottom end of the stud 9 is threaded with the inner wall of the water intake column 1. This makes the groove plate 2 stably installed on the inner wall of the water intake column 1, so that the operator can better control the water pump 42 to draw water from the well to the inside of the box 41 through the water intake column 1.
