Detailed implementation manners

[0033] For ease of understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Typical embodiments of the present invention are shown in the drawings.

[0034] As Figure 1As shown in the figure, an ecological restoration device for groundwater environment provided by the present invention includes a water inlet pipe 4. The output end of the water inlet pipe 4 is detachably connected to a filter box 1. Inside the filter box 1, an inclined filter screen 29 is rotatably connected. One end face of the inclined filter screen 29 is hinged to the end of a top rod 13 below the filter box 1. The output end of the top rod 13 is detachably connected to a first floating ball 12. The top rod 13 is slidably connected inside a first water tank 6. A second water tank 7 is fixedly connected to the side edge of the first water tank 6. A second floating ball 22 is slidably connected inside the second water tank 7. The second floating ball 22 is connected to a support rod 20. One end of the support rod 20 is hinged to a pipe cover 26 inside the filter box 1. The pipe cover 26 covers the port of a sewage pipe 9 of the filter box 1. When backwashing the inclined filter screen 29, it is necessary to first fill the first water tank 6 and the second water tank 7 with water. The top rod 13 can drive the inclined filter screen 29 to rotate, and the support rod 20 can drive the pipe cover 26 to open, so as to realize the backwashing of the inclined filter screen 29. After backwashing, the sewage is discharged through the sewage pipe 9. Through backwashing, the long-term continuous flow of groundwater is ensured.

[0035] As Figure 2 shown in the figure, a three-way valve 3 is detachably connected to the water inlet pipe 4 of the filter box 1. A through pipe 5 is detachably connected to the three-way valve 3. The output end of the through pipe 5 is connected to the first water tank 6. The through pipe 5 and the first water tank 6 are mutually communicated. By connecting the through pipe 5 and the three-way valve 3, the flow direction control of groundwater can be realized. When backwashing the inclined filter screen 29, groundwater can be introduced into the first water tank 6 and the second water tank 7. After the first water tank 6 and the second water tank 7 are continuously filled with water, the first floating ball 12 and the second floating ball 22 can move, so as to drive the corresponding components to move.

[0036] As Figure 3 shown, a bayonet 14 is fixedly connected to the first floating ball 12 inside the first water tank 6. A side seat 15 is fixedly connected to the side edge of the bayonet 14. A plug rod 17 is horizontally arranged on the side seat 15. A push plate 19 is fixedly connected to the plug rod 17 between the outer wall of the side seat 15 and the bayonet 14. A return spring 18 is sleeved on the plug rod 17 on one side of the push plate 19. The first floating ball 12 and the second floating ball 22 are respectively movably connected inside the first water tank 6 and the second water tank 7. The first floating ball 12 is connected to the top rod 13 inside the first water tank 6, and the second floating ball 22 is connected to a collision rod 23 inside the second water tank 7. Bayonets 14 are fixedly connected to both the first floating ball 12 and the second floating ball 22. One side of the bayonet 14 is slidably connected to the plug rod 17. When the first floating ball 12 is connected to the top rod 13 and the second floating ball 22 is connected to the collision rod 23, the plug rods 17 on the first floating ball 12 and the second floating ball 22 can be inserted into the corresponding top rod 13 and collision rod 23, so as to realize the stable connection between the first floating ball 12 and the top rod 13, and the stable connection between the second floating ball 22 and the collision rod 23, thus facilitating the disassembly between components and facilitating the installation and disassembly of the equipment by personnel.

[0037] During implementation, a water inlet pipe 4 is detachably connected to the input end of the filter box 1. A three-way valve 3 is detachably connected to the water inlet pipe 4, and a connecting pipe 5 is detachably connected to the three-way valve 3. The three-way valve 3 can control the flow of groundwater into the filter box 1 or into the connecting pipe 5. The output end of the connecting pipe 5 is connected to a first water tank 6. A second water tank 7 is connected to the side edge of the first water tank 6. A push rod 13 is slidably connected inside the first water tank 6. A first floating ball 12 is detachably connected to the input end of the push rod 13. A striking rod 23 is slidably connected inside the second water tank 7. A second floating ball 22 is detachably connected to the input end of the striking rod 23. When the connecting pipe 5 injects water into the first water tank 6 and the second water tank 7, the first floating ball 12 and the second floating ball 22 can move. The first floating ball 12 can drive the push rod 13 to move inside the filter box 1. The second floating ball 22 can drive the striking rod 23 to move into the linkage box 8. One side end of the push rod 13 is hinged to an inclined filter screen 29 inside the filter box 1. When the push rod 13 moves upward, the input end face of the inclined filter screen 29 can be rotated to the output position. When groundwater flows through the filter box 1, the impurities on the inclined filter screen 29 can be washed away, thus realizing the backwashing of the inclined filter screen 29, ensuring the continuous flow and repair of groundwater. When the second floating ball 22 pushes the striking rod 23, the support rod 20 can be pushed. The support rod 20 will move into the filter box 1. During the movement, the pipe cover 26 at the mouth of the sewage discharge pipe 9 can be pushed, thus opening it, realizing the simultaneous opening of the pipe cover 26 during backwashing, and discharging sewage. After backwashing, the groundwater in the first water tank 6 and the second water tank 7 can be discharged, realizing the reset of the pipe cover 26 and the inclined filter screen 29.

[0038] Such as Figures 4 to 11As shown, a vacancy is provided on the ejector rod 13 corresponding to the insertion rod 17. The insertion rod 17 is inserted into the corresponding vacancy of the ejector rod 13. A pull ring 16 is welded to the outer end of the insertion rod 17. By fixedly connecting the pull ring 16 to one end of the insertion rod 17, a person can insert a finger into the pull ring 16 to pull it. Through the pull ring 16, the manipulation of the insertion rod 17 can be realized, thereby controlling the reciprocating movement of the insertion rod 17.

The output end of the collision rod 23 is in a slope shape. A support rod 20 is slidably connected inside the corresponding linkage box 8 of the collision rod 23. A connecting seat 25 is welded to the input end of the support rod 20. An inclined head 21 is fixedly connected to the input end of the connecting seat 25. The output end of the collision rod 23 corresponds to the position of the inclined head 21 of the support rod 20. When the collision rod 23 moves with the second floating ball 22, it can squeeze the inclined head 21. When the inclined head 21 is squeezed by the collision rod 23, it will move towards the inside of the filter box 1. The inclined head 21 is connected to the connecting seat 25, and the connecting seat 25 is connected to the support rod 20. The support rod 20 will move with the movement of the inclined head 21 and move towards the inside of the filter box 1.

A hinge joint 28 is welded to the other side of the pipe cover 26. The fixing frame 27 fixed to one side of the sewage discharge pipe 9 inside the filter box 1 can limit the pipe cover 26, and the pipe cover 26 can rotate around the fixing frame 27. When the pipe cover 26 rotates, the opening or closing of the sewage discharge pipe 9 can be realized. When it is closed, the normal circulation of groundwater is realized. When it is opened, the backwashed sewage can be discharged. The hinge joint 28 is hinged to the corresponding support rod 20. The support rod 20 is vertically slidably connected to the filter box 1. The support rod 20 is perpendicular to the collision rod 23 in the second water tank 7. By fixing the hinge joint 28 on the pipe cover 26, the hinge joint 28 can be hinged to one side end of the support rod 20. When the support rod 20 moves towards the inside of the filter box 1, it can push the pipe cover 26, thereby realizing that the support rod 20 pushes the pipe cover 26 open or closed.

[0040] The inner support rod 20 and the top rod 13 in the filter box 1 are parallel to each other. The obliquely arranged filter screen 29 hinged to the top rod 13 is rotatably connected obliquely inside the filter box 1. Both sides of the obliquely arranged filter screen 29 are fixedly connected with rotating rods 30. The rotating rods 30 are rotatably connected to the side edge of the filter box 1. A sector seat 37 is fixedly connected to the rotating rod 30. A horizontal groove 36 is provided on the side edge of the filter box 1 in the rotating direction of the sector seat 37.

The top rod 13 and the support rod 20 are arranged in parallel. The support rod 20 will move when the top rod 13 moves first, so as to ensure that the obliquely arranged filter screen 29 is adjusted first and then opened. The synchronous rotation can be realized by arranging the rotating rods 30 on the obliquely arranged filter screen 29. The rotating rods 30 can drive the sector seat 37 to rotate. The sector seat 37 can pull the arc-shaped frame 35 through the movable frame 32. The arc-shaped frame 35 can pull the pull rope 34. The pull rope 34 can lift the outer net 33 on the obliquely arranged filter screen 29. When lifted, the attached dust can be loosened, which is convenient for flushing.

[0041] As an alternative solution, in this embodiment, as Figure 1 shown, a water outlet pipe 10 is detachably connected to the other end of the filter box 1. An embolism pump 11 is detachably connected to the output end of the water outlet pipe 10. An outer cylinder 39 is fixedly connected to the outside of the filter box 1. A downward moving rod 38 is slidably connected inside the outer cylinder 39. The output end of the downward moving rod 38 is fixedly connected with an inner frame 42. The inner frame 42 is U-shaped. A scraping wheel 41 is rotatably connected inside the inner frame 42. The normal flow of groundwater can be realized through the water outlet pipe 10 when the equipment is used for ecological restoration. The scraping wheel 41 is impelled by the water flow and thus rotates. When the scraping wheel 41 rotates, the impurities on the outer net 33 outside the obliquely arranged filter screen 29 can be scraped off.

[0042] During implementation, bayonets 14 are fixedly connected to both the first floating ball 12 and the second floating ball 22. A side seat 15 is fixedly connected to each bayonet 14. There is a certain space between the side seat 15 and the outer wall of the bayonet 14. A push rod 17 can be slidably connected between the side seat 15 and the bayonet 14. A push plate 19 can be fixedly connected to the push rod 17 between the side seat 15 and the outer wall of the bayonet 14. A return spring 18 is sleeved on the push rod 17 on one side of the push plate 19. The return spring 18 can push the push rod 17 to maintain a state of moving towards the position of the ejector rod 13. When the ejector rod 13 is inserted into the bayonet 14, the push rod 17 can move towards the corresponding position of the push rod 17 under the drive of the return spring 18. The push rod 17 can be inserted onto the ejector rod 13, so that the floating ball is fixedly connected to the corresponding support rod 20 and the ejector rod 13. During disassembly, the pull ring 16 is pulled outwards. The pull ring 16 is convenient for a person's finger to hook, and it is also convenient to control the push rod 17 through the pull ring 16. The push rod 17 can be pulled outwards through the pull ring 16, and the push rod 17 can be pulled out of the ejector rod 13, so as to realize the disassembly of the floating ball.

When the ejector rod 13 is pushed up, the input end face of the inclined filter screen 29 can be rotated to the output position;

[0047] Step 3: When groundwater flows through the filter box 1, the impurities on the inclined filter screen 29 can be washed away, thereby realizing the backwashing of the inclined filter screen 29, ensuring the continuous flow and repair of groundwater. When the second float ball 22 pushes the impact rod 23, the support rod 20 can be pushed. The support rod 20 will move into the filter box 1. During the movement, the pipe cover 26 at the mouth of the sewage pipe 9 can be pushed, thereby opening it, realizing the simultaneous opening of the pipe cover 26 during backwashing, and discharging sewage. After backwashing, the groundwater in the first water storage tank 6 and the second water storage tank 7 can be discharged, realizing the reset of the pipe cover 26 and the inclined filter screen 29.

[0048] Second implementation step:

[0049] Step 1: By fixedly connecting bayonets 14 to both the first float ball 12 and the second float ball 22, a side seat 15 is fixedly connected to each bayonet 14. There is a certain space between the outer wall of the side seat 15 and the bayonet 14. An insertion rod 17 can be slidably connected between the side seat 15 and the bayonet 14. A push plate 19 can be fixedly connected to the insertion rod 17 between the outer wall of the side seat 15 and the bayonet 14. A return spring 18 is sleeved on the insertion rod 17 on one side of the push plate 19;

[0050] Step 2: The return spring 18 can hold the insertion rod 17 in a state of moving towards the ejector rod 13. When the ejector rod 13 is inserted into the bayonet 14, the insertion rod 17 can move to the corresponding position of the insertion rod 17 under the drive of the return spring 18, and the insertion rod 17 can be inserted into the ejector rod 13, thereby fixedly connecting the float ball to the corresponding support rod 20 and ejector rod 13. When disassembling, pull the pull ring 16 outwards;

[0051] Step 3: The pull ring 16 is convenient for a person's finger to hook, and is also convenient for controlling the insertion rod 17. The insertion rod 17 can be pulled outwards through the pull ring 16, and the insertion rod 17 can be pulled out of the ejector rod 13, thereby realizing the disassembly of the float ball. Through the setting, the assembly of the float ball can be realized, facilitating the quick disassembly and assembly between components.
