Description

Technical Field

[0001] This utility model relates to the field of municipal water supply and drainage, and in particular to a water supply and drainage filtration device that is easy to clean. Background Technology

[0002] Water supply and drainage generally refers to urban water supply systems and drainage systems (municipal water supply and drainage and building water supply and drainage). Water supply and drainage pipeline engineering is an integral part of the municipal water supply and drainage system and plays an important role in the entire water supply and drainage system.

[0003] Common drainage treatment filtration equipment installs filter screens in drainage ditches to intercept and treat impurities in the water, thereby achieving the effect of filtering and purifying water supply and drainage.

[0004] In existing technologies, when a filter screen gradually becomes clogged with impurities and needs cleaning, the drainage channel must first be stopped, the filter screen must be manually disassembled, and then tools must be used to clean the impurities from the filter screen. After cleaning, the filter screen is then reinstalled inside the drainage channel before the gate is opened to release water. Therefore, during the cleaning process, the filtration device cannot purify the drainage, thus affecting the drainage efficiency and overall operating time of the water supply and drainage filtration system. To address this issue, a water supply and drainage filtration device that is easy to clean is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3This utility model provides an embodiment of a water supply and drainage filtration device that is easy to clean. It includes a drainage channel 1 and a first filter plate 4 and a second filter plate 5 installed on the drainage channel 1. Both the first and second filter plates 4 and 5 are rectangular. The outer sides of the first and second filter plates 5 are in contact with the inner walls of the drainage channel 1. The first and second filter plates 4 and 5 effectively filter the interior of the drainage channel 1. Two strip-shaped holes are respectively opened at the top of the drainage channel 1 to improve the stability of the first and second filter plates 4 and 5 during movement within the drainage channel 1. The first and second filter plates 4 and 5 are in contact with and slidably connected to the walls of the two strip-shaped holes, allowing the first filter plate 4... The second filter plate 5 can be lifted upwards through the strip-shaped holes. A lifting assembly is provided between the first filter plate 4 and the second filter plate 5. The lifting assembly includes limit blocks 2, which are fixedly connected to the top of the drainage ditch 1. There are four limit blocks 2, which are symmetrically and fixedly connected to the top of the drainage ditch 1. There are two sets of limit blocks 2, with two limit blocks 2 in each set. The symmetrically arranged limit blocks 2 can limit the sides of the first filter plate 4 and the second filter plate 5. The sides of the first filter plate 4 and the second filter plate 5 are slidably connected to the sliding grooves 3 opened in the two sets of limit blocks 2. The first filter plate 4 and the second filter plate 5 pass through the sliding grooves 3 opened in the limit blocks 2. The sliding mechanism limits the movement of filter plates 4 and 5, improving their stability during operation. A top plate 6 and a top plate 8 are fixedly connected to the top of drainage channel 1. Each top plate 6 and top plate 8 has two sliding holes 10. Connecting blocks 13 are fixedly connected to the tops of filter plates 4 and 5. A telescopic rod 7 is hinged to the inner side of each connecting block 13. The connecting block 13 is U-shaped with an arc-shaped top surface. The inner side of the connecting block 13 contacts the outer side of the telescopic rod 7, allowing the telescopic rod 7 to rotate around the inner side of the connecting block 13, further extending and retracting its telescopic end. A central column 18 is fixedly connected to the telescopic end of the telescopic rod 7. There are two telescopic rods 7, and their telescopic ends are fixedly connected to the two ends of the central column 18. The surface of the central column 18 has two No. 3 sliding holes 14, which limit the movement of the sliding rod 11. The inner walls of the No. 2 sliding hole 10 and the No. 3 sliding hole 14 are slidably connected to the sliding rod 11, allowing the sliding rod 11 to slide within them. A rotating rod 12 is rotatably connected to the surface of the central column 18, allowing the central column 18 to rotate around one end of the rotating rod 12. Filter assemblies are installed on the No. 1 top plate 6 and the No. 2 top plate 8. A threaded hole is provided on one side of the limiting block 2, and a threaded groove is provided on one side of the No. 1 filter screen plate 4 and the No. 2 filter screen plate 5. Bolts are threadedly connected to the threaded holes and threaded grooves.After alternately raising and lowering filter screen 4 or filter screen 5, the filter screen is installed using the side bolts of the limit block 2, allowing for easy cleaning of the raised filter screen 4 or filter screen 5.

[0026] Reference Figure 2 , Figure 4 The filter assembly includes a rectangular movable block 16. The movable block 16 contacts and slides against the side of the second top plate 8. The movable block 16 can move along one side of the second top plate 8, improving its stability. The other end of the movable block 16 is fixedly connected to the rotating rod 12. A telescopic motor 15 is fixedly installed on one side of the second top plate 8. The telescopic end of the telescopic motor 15 is fixedly connected to the top of the movable block 16. The telescopic end of the telescopic motor 15 pushes the movable block 16 up and down. A sliding hole 9 is provided on the side of the second top plate 8 near the telescopic motor 15. The surface of the rotating rod 12 contacts and slides against the wall of the sliding hole 9. The sliding hole 9 limits the movement of the rotating rod 12, allowing the central column 18 to rotate around the rotating rod 12 and also allowing the rotating rod 12 to move in a certain direction. The filter slides downwards through the sliding hole 9. Once the first filter plate 4 and the second filter plate 5 are horizontal, they simultaneously intercept the internal components of the drainage channel 1, improving interception efficiency and allowing for switching between different filtration modes. The surfaces of the moving block 16 and the two sliding rods 11 are provided with insertion holes 17. Insert rods 19 are connected through the walls of the insertion holes 17. The insertion holes 17 are horizontally arranged. To determine if the central column 18 and the telescopic rod 7 are horizontal, simply insert the insertion rod 19 into the insertion holes 17 provided by the sliding rod 11 and the moving block 16. This achieves the self-locking function of rotating the central column 18 to the horizontal direction. When the insertion rod 19 cannot be inserted into the insertion hole 17, i.e., the first filter plate 4 and the second filter plate 5 are not on the same horizontal plane, nuts are threaded to both ends of the insertion rod 19. The nuts contact the side adjacent to the sliding rod 11, limiting the two ends of the insertion rod 19 to prevent it from falling out of the insertion hole.

[0027] Working principle: Rotating the central column 18 around one end of the rotating rod 12 causes the telescopic end of the telescopic rod 7 to extend and retract, causing the sliding rod 11 to slide within the third sliding hole 14 opened in the central column 18. This causes the telescopic rod 7 to rotate around the inner side of the connecting block 13, causing the first filter plate 4 and the second filter plate 5 to move within the opened strip-shaped holes, thus alternately raising and lowering the first filter plate 4 and the second filter plate 5. The first filter plate 4 and the second filter plate 5 slide within the sliding groove 3 opened in the limiting block 2, thereby adjusting the pressure on the filter plate. Filter plates 4 and 5 act as limiters, improving their stability during movement. After alternating raising and lowering of either filter plate 4 or filter plate 5, they are replaced alternately using bolts on the side of the limit block 2. This facilitates cleaning of the raised filter plate 4 or filter plate 5. The other filter plate also acts as an interceptor in the drainage channel 1. When the interception efficiency of drainage channel 1 needs to be improved, simply rotate the central column 18 around... When the rotating rod 12 rotates to the horizontal direction, to determine if the central column 18 and the telescopic rod 7 are in a horizontal state, simply insert the insertion rod 19 into the insertion hole 17 opened in the sliding rod 11 and the moving block 16, and then tighten the nuts to both ends of the insertion rod 19. The nuts limit the two ends of the insertion rod 19 to prevent it from falling out of the insertion hole, thus achieving the self-locking function of the central column 18 rotating to the horizontal direction. When the insertion rod 19 cannot be inserted into the opened insertion hole 17, that is, when the first filter screen 4 and the second filter screen 5 are not in the same position... A horizontal plane is formed; then the telescopic motor 15 is started. The telescopic end of the telescopic motor 15 pushes the moving block 16 downward. The rotating rod 12 on the side of the moving block 16 slides downward in the first sliding hole 9, thereby driving the first filter screen 4 and the second filter screen 5 to move downward until the first filter screen 4 and the second filter screen 5 simultaneously enter the interior of the drainage ditch 1. The first filter screen 4 and the second filter screen 5 simultaneously achieve the interception effect inside the drainage ditch 1, improve the interception efficiency, and thus switch between different filtration modes.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
