Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and more specifically, to a municipal drainage filtration structure. Background Technology

[0002] Urban drainage refers to the collection, transportation, treatment, and discharge of urban sewage and rainwater by urban drainage systems. When dealing with rainwater, most cities use urban drainage to discharge rainwater into the urban groundwater network through roadside manhole covers and send it to ditches and rivers around the city. During the collection process, rainwater inevitably contains a lot of impurities, which makes it difficult to recycle and reuse rainwater. In the process of municipal drainage, the water flow needs to be filtered, so a filtration structure is required.

[0003] Existing filtration structures typically use filter plates for filtration, which are placed at the water inlet. These plates effectively filter and block impurities such as dust, mud, and leaves from the water flow through their surface pores. However, in actual use, the following problems exist: after prolonged use, impurities easily accumulate on the surface of the filter plate, eventually clogging the pores. This affects the filter plate's performance and causes inconvenience for staff. Therefore, we propose a municipal drainage filtration structure to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a municipal drainage filtration structure that is easy to maintain.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a municipal drainage filtration structure, comprising a housing, with mounting shells fixedly connected to both sides of the inner cavity of the housing, a nut fixedly connected to the top of the inner cavity of the mounting shell, a locking bolt threaded into the inner cavity of the nut, a bearing body rotatably connected to the bottom of the locking bolt, a sliding plate fixedly connected to the bottom of the bearing body, an insert rod fixedly connected to the bottom of the sliding plate, a filter plate inserted through the bottom of the insert rod to the outside of the mounting shell, springs fixedly connected to both sides of the bottom of the sliding plate, and a mesh plate fixedly connected to the top of the housing.

[0008] As a preferred embodiment, a housing is fixedly connected to one side of the top of the housing, a motor is fixedly installed on the right side of the inner cavity of the housing, a threaded rod is fixedly connected to the left side of the motor, a threaded sleeve is threadedly connected to the surface of the threaded rod, a connecting rod is fixedly connected to the bottom of the threaded sleeve, a cleaning brush is fixedly connected to the bottom of the connecting rod, and the bottom of the cleaning brush is attached to the surface of the filter plate.

[0009] The above technical solution uses a motor to easily drive the threaded rod to rotate. Since the threads on the surface of the threaded rod and the threads in the inner cavity of the threaded sleeve are connected by threads, when the threaded rod rotates, it drives the threaded sleeve to move. The threaded sleeve then drives the connecting rod to move, which in turn drives the cleaning brush to move. This effectively cleans the dried mud on the surface of the filter plate during drainage, preventing the dried mud from clogging the filter holes on the surface of the filter plate and improving the smoothness of water flow.

[0010] As a preferred embodiment, a limiting groove is formed at the top of the inner cavity of the housing, and a slider is fixedly connected to the top of the threaded sleeve, with the surface of the slider slidably connected to the inner cavity of the limiting groove.

[0011] The above technical solution, through the limiting groove, facilitates the limiting of the slider and improves the stability of the threaded sleeve sliding.

[0012] As a preferred embodiment, a bearing is fixedly connected to the left side of the inner cavity of the housing, and the left side of the threaded rod is rotatably connected to the inner cavity of the bearing.

[0013] The above technical solution, through the use of bearings, improves the stability of the threaded rod rotation.

[0014] As a preferred embodiment, the inner cavity of the mounting shell is provided with sliding grooves on both sides, and the two sides of the sliding plate are slidably connected to the inner cavity of the sliding grooves.

[0015] The above technical solution improves the stability of the sliding plate by using the groove.

[0016] As a preferred embodiment, a placement groove is provided at the bottom of the mounting shell surface, and the surface of the filter plate is fitted and connected to the inner cavity of the placement groove.

[0017] The above technical solution facilitates the placement of the filter plate through the placement groove.

[0018] As a preferred embodiment, the filter plate has slots on both sides, and the bottom of the insertion rod is inserted into the inner cavity of the slot.

[0019] The above technical solution facilitates the insertion of the plug rod through the socket.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a municipal drainage filtration structure with the following beneficial effects.

[0022] 1. This utility model allows the locking bolt to rotate within its inner cavity via a nut and bearing body. Since the threads on the locking bolt surface and the threads in the nut's inner cavity are threadedly connected, the rotation of the locking bolt allows it to move. For example, when the locking bolt rotates clockwise, it moves downwards; conversely, when it rotates counterclockwise, it moves upwards. This counterclockwise movement of the locking bolt drives the bearing body to move, which in turn drives the sliding plate. The sliding plate then drives the insertion rod to move, disengaging it from the insertion slot on the filter plate surface. This facilitates the release of the filter plate from its limiting position, making maintenance and cleaning easier. The spring effectively utilizes elasticity to push the sliding plate back to its original position, significantly accelerating the time it takes for the sliding plate to retract and move the insertion rod, thus improving the efficiency of filter plate disassembly.

[0023] 2. This utility model uses a motor to easily drive the threaded rod to rotate. Since the threads on the surface of the threaded rod and the threads in the inner cavity of the threaded sleeve are connected by threads, when the threaded rod rotates, it drives the threaded sleeve to move. The threaded sleeve then drives the connecting rod to move, and the connecting rod then drives the cleaning brush to move. This effectively cleans the dried mud on the surface of the filter plate during drainage, preventing the mud from drying and clogging the filter holes on the surface of the filter plate, thus improving the smoothness of water flow. The limiting groove facilitates the limiting of the slider, improving the stability of the sliding of the threaded sleeve. The bearing improves the stability of the rotation of the threaded rod.

[0028] 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, not all embodiments. The control method can be implemented by simple programming by those skilled in the art and belongs to common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the protection scope of the present utility model.

[0029] Example 1;

[0030] Please see Figure 1 and Figure 3 This utility model discloses a municipal drainage filtration structure, comprising a housing 1, with mounting shells 6 fixedly connected to both sides of the inner cavity of the housing 1, a nut 12 fixedly connected to the top of the inner cavity of the mounting shell 6, a locking bolt 5 threadedly connected to the inner cavity of the nut 12, a bearing body 13 rotatably connected to the bottom of the locking bolt 5, a sliding plate 17 fixedly connected to the bottom of the bearing body 13, an insertion rod 15 fixedly connected to the bottom of the sliding plate 17, a filter plate 8 inserted through the bottom of the insertion rod 15 to the outside of the mounting shell 6, springs 16 fixedly connected to both sides of the bottom of the sliding plate 17, and a mesh plate 2 fixedly connected to the top of the housing 1.

[0031] Through the above technical solution, the locking bolt 5 can rotate in its inner cavity via the nut 12 and the bearing body 13. Since the threads on the surface of the locking bolt 5 and the threads in the inner cavity of the nut 12 are threadedly connected, the locking bolt 5 can move when it rotates. For example, when the locking bolt 5 rotates clockwise, it moves downwards, and conversely, when the locking bolt 5 rotates counterclockwise, it moves upwards. The counterclockwise movement of the locking bolt 5 drives the bearing body 13 to move, which in turn drives the sliding plate 17 to move. The sliding plate 17 then drives the insertion rod 15 to move. The movement of the insertion rod 15 disengages it from the insertion hole on the surface of the filter plate 8, making it easier to release the filter plate 8 from its limit and facilitate its maintenance and cleaning. The spring 16 can effectively use its elasticity to push the sliding plate 17 to reset and move, which can effectively speed up the time for the sliding plate 17 to retract and move the insertion rod 15, thus improving the efficiency of disassembling the filter plate 8.

[0032] Example 2;

[0033] like Figure 1-2As shown, a housing 3 is fixedly connected to one side of the top of the housing 1. A motor 11 is fixedly installed on the right side of the inner cavity of the housing 3. A threaded rod 9 is fixedly connected to the left side of the motor 11. A threaded sleeve 10 is threadedly connected to the surface of the threaded rod 9. A connecting rod 4 is fixedly connected to the bottom of the threaded sleeve 10. A cleaning brush 7 is fixedly connected to the bottom of the connecting rod 4. The bottom of the cleaning brush 7 is attached to the surface of the filter plate 8.

[0034] Through the above technical solution, the motor 11 facilitates the rotation of the threaded rod 9. Since the threads on the surface of the threaded rod 9 and the threads in the inner cavity of the threaded sleeve 10 are connected by threads, when the threaded rod 9 rotates, it drives the threaded sleeve 10 to move. The threaded sleeve 10 then drives the connecting rod 4 to move, and the connecting rod 4 then drives the cleaning brush 7 to move. This effectively cleans the dried mud on the surface of the filter plate 8 during drainage, preventing the dried mud from clogging the filter holes on the surface of the filter plate 8 and improving the smoothness of water flow.

[0035] Example 3;

[0036] like Figure 1-3 As shown, a limiting groove is provided at the top of the inner cavity of the housing 3. A slider is fixedly connected to the top of the threaded sleeve 10, and the surface of the slider is slidably connected to the inner cavity of the limiting groove. A bearing is fixedly connected to the left side of the inner cavity of the housing 3. The left side of the threaded rod 9 is rotatably connected to the inner cavity of the bearing. Sliding grooves are provided on both sides of the inner cavity of the mounting housing 6. Both sides of the sliding plate 17 are slidably connected to the inner cavity of the sliding groove. A placement groove 14 is provided at the bottom of the surface of the mounting housing 6. The surface of the filter plate 8 is fitted and connected to the inner cavity of the placement groove 14. Insertion ports are provided on both sides of the filter plate 8. The bottom of the insertion rod 15 is inserted into the inner cavity of the insertion port.

[0037] The above technical solution facilitates the limiting of the slider by using the limiting groove, thereby improving the sliding stability of the threaded sleeve 10 and improving the rotational stability of the threaded rod 9 by using the bearing.

[0038] The working principle of this utility model is as follows: First, when it rains, rainwater flows through the mesh plate 2 into the inner cavity of the housing 1 and falls onto the surface of the filter plate 8. The mesh plate 2 effectively blocks impurities mixed in with the water flow, such as plastic bags, branches, etc. While the rainwater is flowing, the user starts the motor 11 to rotate forward via an external controller. The motor 11 has forward and reverse rotation functions. The motor 11 facilitates the rotation of the threaded rod 9. Since the threads on the surface of the threaded rod 9 and the threads in the inner cavity of the threaded sleeve 10 are threadedly connected, when the threaded rod 9 rotates, it drives the threaded sleeve 10 to move. The threaded sleeve 10 then drives the connecting rod 4 to move, which in turn drives the cleaning brush 7 to move. This effectively cleans the dried mud on the surface of the filter plate 8 during drainage, preventing the mud from drying and clogging the filter holes on the surface of the filter plate 8, thus improving the smoothness of water flow. At the same time, the filter plate 8 facilitates the removal of water... The filter plate 8 is filtered. When it needs maintenance after long-term use, the user turns the locking bolt 5 in reverse. The locking bolt 5 rotates in the inner cavity of the bearing body 13 and the nut 12. Since the threads on the surface of the locking bolt 5 and the threads in the inner cavity of the nut 12 are threadedly connected, the locking bolt 5 can move when it rotates. For example, when the locking bolt 5 rotates clockwise, it moves downwards, and when it rotates counterclockwise, it moves upwards. After the locking bolt 5 moves in reverse, the downward pressure on the bearing body 13 and the sliding plate 17 is eliminated, and the spring 16 automatically resets. The spring 16 can effectively use its elasticity to push the sliding plate 17 to reset and move. The sliding plate 17 drives the insertion rod 15 to move. The insertion rod 15 moves and disengages from the insertion hole on the surface of the filter plate 8, making it easy to release the limit on the filter plate 8 and facilitate its maintenance and cleaning.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
