Description

Technical Field

[0001] This utility model relates to the field of groundwater screen pipe technology, specifically, to a groundwater screen pipe. Background Technology

[0002] A groundwater screen (also known as a well screen or well tube screen) is a device used in water wells. Its main function is to allow groundwater to flow into the well while preventing larger particles and sediments from entering. Screens are typically made of metal, plastic, or other durable materials and have holes or slits on their surface. The size and shape of these holes or slits can be designed according to the size of the particles that need to be filtered.

[0003] After a period of use, the pores inside common groundwater screens used to filter larger particles become clogged with a large amount of impurities, severely affecting the water output of the screens. At this point, users need to clean the screens. Cleaning common groundwater screens is very troublesome and requires disassembly, which seriously affects the lifespan and cleaning efficiency of the screens. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-5 In this utility model: a groundwater screen pipe includes an inlet pipe 1, the top of which is closed. A sleeve 2 is fitted onto the inlet pipe 1 and fixedly connected thereto. An outlet pipe 3, which is connected to the top of the sleeve 2, is fixedly connected thereto. A ring-shaped filter groove 4 is formed on the inlet pipe 1. An adjusting strip 5 is slidably connected to the inner wall of the filter groove 4. The adjusting strip 5 has an isosceles trapezoidal cross-section. A horizontal bar 6 is fixedly connected to one side of the adjusting strip 5, and a vertical bar 7 is fixedly connected to the bottom of the horizontal bar 6. The inner wall of the inlet pipe 1 is fixedly connected to... A limiting plate 8 is provided, and a ring-shaped limiting groove 9 is provided on the limiting plate 8. The inner wall of the limiting groove 9 is slidably connected to the vertical rod 7. A limiting rod 10 is fixedly connected to the inner wall of the limiting groove 9. The vertical rod 7 is sleeved on the limiting rod 10 and slidably connected to it. A motor 11 is installed at the top of the water inlet pipe 1. A lead screw 12 is fixedly connected to the output shaft of the motor 11. An adjusting plate 13 is sleeved on the lead screw 12 and threadedly connected to it. A ring-shaped trapezoidal groove 14 is provided at the top of the adjusting plate 13. The inner wall of the trapezoidal groove 14 is in contact with the vertical rod 7.

[0026] In this invention, the inlet pipe 1 is used to connect the groundwater inlet, and the outlet pipe 3 is used to connect the groundwater outlet. When filtering the groundwater, the groundwater first enters the inlet pipe 1. In the groundwater filtering state, the gap between the adjusting strip 5 and the filter tank 4 is small, and the groundwater can pass through the gap between the adjusting strip 5 and the filter tank 4. Large particles in the groundwater will be blocked, thereby achieving the effect of filtering the groundwater. The filtered groundwater will enter the sleeve 2 and be discharged from the outlet pipe 3, thus completing the filtration of the groundwater.

[0027] The vertical rod 7 is positioned by the limiting groove 9 and the limiting rod 10. Therefore, the position of the adjusting strip 5 is positioned by the cooperation of the horizontal rod 6 and the vertical rod 7. Moreover, the groundwater continues to flow outward, and the power generated by the groundwater flow will push the adjusting strip 5 to tend to move outward towards the outside of the water inlet pipe 1. The inclined surface of the trapezoidal groove 14 will limit the position of the vertical rod 7, thereby achieving the effect of limiting the position of the adjusting strip 5, keeping the gap between the adjusting strip 5 and the filter tank 4 unchanged, and improving the stability of groundwater filtration.

[0028] After prolonged use, the gap between the adjusting strip 5 and the filter tank 4 will become clogged with a large amount of impurities, affecting the water output of the outlet pipe 3. When this happens, the user only needs to turn on the motor 11. The motor 11 will drive the lead screw 12 to rotate. The lead screw 12 is threadedly connected to the adjusting plate 13, and the vertical rod 7 will be limited by the adjusting plate 13 through the trapezoidal groove 14. Therefore, after the motor 11 is turned on, it will drive the adjusting plate 13 to descend. After the adjusting plate 13 descends, the inclined surface of the trapezoidal groove 14 will temporarily lose its limiting effect on the vertical rod 7. At this time, the adjusting strip 5 will lose its limiting effect, and the groundwater will push the adjusting strip 5 to move to the outside of the inlet pipe 1 until the vertical rod 7 re-contacts the inclined surface of the trapezoidal groove 14, thereby repositioning the adjusting strip 5. The gap between the adjusted strip 5 and the filter tank 4 will increase after the position is changed. At this time, the large particles filtered out will be carried out by the groundwater from the outlet pipe 3, thereby achieving the cleaning effect of the groundwater screen pipe. After cleaning, the user can turn on the motor 11 in reverse to reset the position of the adjusting strip 5, and then continue to filter the groundwater.

[0029] Please see Figure 3 Among them, the bottom of the limiting plate 8 is fixedly connected to a closing ring 15, and the inner side of the closing ring 15 is in contact with the adjusting plate 13.

[0030] In this invention, the closed ring 15 can effectively prevent groundwater from entering between the limiting plate 8 and the adjusting plate 13, reduce the occurrence of impurities in the groundwater falling into the trapezoidal groove 14, and improve the stability of the adjustment of the adjusting strip 5.

[0031] Please see Figure 3 The inner wall of the closed ring 15 is fixedly connected to two sliders 16, and the outer side of the adjusting plate 13 has two sliding grooves 17 that are slidably connected to the sliders 16.

[0032] In this invention, the slider 16 and the groove 17 can improve the limiting effect on the adjustment plate 13, thereby improving the practicality of the device.

[0033] Please see Figure 3 The bottom end of the vertical rod 7 is rotatably connected to a roller 18, and the outer side of the roller 18 is in contact with the inner wall of the trapezoidal groove 14.

[0034] In this invention, the roller 18 can reduce friction, reduce wear, and improve the service life of the device.

[0035] Please see Figure 3 The top end of the lead screw 12 is fixedly connected to a limiting ring 19, and the outer side of the limiting ring 19 is rotatably connected to the water inlet pipe 1.

[0036] In this invention, the setting of the limiting ring 19 can improve the stability of the lead screw 12 and enhance the stability of the device in use.

[0037] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
