Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation technology, and in particular to a rainwater and sewage separation anti-backflow device. Background Technology

[0002] Rainwater and sewage separation, a key component of sponge cities, is a type of drainage system. Under this system, rainwater and sewage are separated and transported through individual pipes for discharge or subsequent treatment. This is the rainwater and sewage separation method. Rainwater and sewage separation facilitates rainwater collection and utilization, allows for centralized management of rainwater discharge, reduces the impact of water volume on sewage treatment plants, and ensures the treatment efficiency of sewage treatment plants.

[0003] Chinese Patent No. CN218911698U discloses a backflow prevention rainwater and sewage diversion device, including a housing. The housing has an inlet pipe at the top and an outlet pipe on one side wall at the bottom. A sewage collection assembly is installed inside the housing. This assembly includes a support frame located inside the housing and below the inlet pipe. A filter plate is mounted on the support frame, with its top surface inclined. The filter plate is also inclined at the top of the support frame. A collection container is installed at one end of the support frame, with an inlet on the side of the container near the support frame. This device uses a sewage collection assembly and connects to a sewage pipe via an external sewage pump to extract sewage from the collection container. This facilitates the collection of sewage from rainwater, making it easier to treat the sewage and preventing it from clogging underground pipes, thus aiding in the cleaning of impurities in the pipes.

[0004] However, the above technical solution has the following shortcomings: when the filter plate is in use, dirt will continuously clog the filter holes of the filter plate, which will cause the filter plate to fail to play a good filtering role, reduce the efficiency of rainwater and sewage diversion, and reduce the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a rainwater and sewage diversion and backflow prevention device, which can not only effectively divert rainwater and sewage, but also prevent dirt from clogging the filter holes of the filter plate, thus ensuring the efficiency of diversion.

[0006] The present invention provides a rainwater and sewage diversion anti-backflow device, comprising a housing and a cleaning mechanism. The housing contains a filter frame with two rotating shafts, on which a filter plate is mounted. The rotating shafts are rotatably connected to the housing. The cleaning mechanism includes a first fixing block and a second fixing block respectively mounted on the housing and the filter plate, a first connecting member and a second connecting member rotatably connected to the first and second fixing blocks respectively, a connecting rod mounted on the first connecting member, a telescopic rod slidably connected to the connecting rod, a spring mounted inside the telescopic rod, a fixing plate inside the housing, and multiple insert rods mounted on the fixing plate. The diameter of the insert rods is smaller than the aperture of the filter plate, and the end of the spring furthest from the telescopic rod is mounted on the connecting rod.

[0007] Preferably, a baffle plate is provided on the casing.

[0008] Preferably, the filter frame is provided with two symmetrically distributed stabilizing blocks, and the housing is provided with an arc-shaped sliding groove for the stabilizing blocks to slide.

[0009] Preferably, the inside of the housing is provided with a collection trough, which is located below the bottom of the filter frame, and the collection trough is at a horizontal distance from the side of the fixing plate.

[0010] Preferably, a sludge suction pipe is installed inside the box, with one end of the sludge suction pipe located inside the collection tank.

[0011] Preferably, the interior of the box is provided with a partition, and the partition has through holes.

[0012] Preferably, a drain pipe is provided on the box body, and the drain pipe is located below the partition.

[0013] Preferably, a concrete base is provided on the box body, and multiple steel columns are provided on the concrete base.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model utilizes a cleaning mechanism that leverages the impact force generated when rainwater and dirt fall to cause the filter frame to swing via a rotating shaft. This causes the filter plate to adhere to a fixed plate, and a rod on the fixed plate penetrates the filter holes on the filter plate to push out the dirt clogging the holes. This prevents the filter plate from becoming heavily clogged after prolonged use, ensuring the filtration efficiency of the filter plate. Furthermore, the spring mechanism helps to buffer and absorb the impact force and restore the filter plate to its original position, making it highly practical. Attached Figure Description

[0022] Example 1

[0023] like Figures 1-5 As shown, the rainwater and sewage diversion anti-backflow device proposed in this embodiment includes a housing 1 and a cleaning mechanism; a guide plate 2 is provided on the housing 1, and a filter frame 3 with two rotating shafts 4 is provided inside the housing 1. A filter plate 5 is provided on the filter frame 3, and the rotating shafts 4 are rotatably connected to the housing 1.

[0024] The cleaning mechanism includes a first fixing block 9 and a second fixing block 13 respectively installed on the housing 1 and the filter plate 5, a first connecting member 10 and a second connecting member 12 respectively rotatably connected to the first fixing block 9 and the second fixing block 13, a connecting rod 11 installed on the first connecting member 10, a telescopic rod 23 slidably connected to the connecting rod 11, a spring 22 installed inside the telescopic rod 23, a fixing plate 7 installed inside the housing 1, and a plurality of insert rods 8 installed on the fixing plate 7; the diameter of the insert rods 8 is smaller than the aperture of the filter plate 5, and the end of the spring 22 away from the telescopic rod 23 is installed on the connecting rod 11.

[0025] The filter frame 3 is provided with two symmetrically distributed stabilizing blocks 14, and the housing 1 is provided with an arc-shaped sliding groove 15 for the stabilizing blocks 14 to slide. The stabilizing blocks 14 and the arc-shaped sliding groove 15 play a guiding and stabilizing role for the swing of the filter frame 3, ensuring that the insertion rod 8 can be accurately inserted into the filter hole of the filter plate 5. At the same time, the groove length of the arc-shaped sliding groove 15 avoids the filter frame 3 from swinging too much and colliding with the fixed plate 7.

[0026] In this embodiment, when rainwater falls onto the housing 1, it enters the housing 1 along the guide plate 2. After falling onto the filter frame 3, the rainwater flows downwards along the filter frame 3. Simultaneously, when a large amount of rainwater falls onto the filter frame 3, it causes the filter frame 3 to experience a downward impact force, causing the filter frame 3 to swing via the rotating shaft 4. Rainwater drips downwards through the filter holes on the filter plate 5. The rotating filter frame 3 causes the filter plate 5 to swing, making the filter plate 5 adhere to the fixing plate 7. This allows the insertion rod 8 on the fixing plate 7 to penetrate the filter holes on the filter plate 5, pushing out the dirt clogging the filter holes and preventing... After prolonged use, the filter plate 5 experiences significant clogging of its filter holes. This ensures the filtration efficiency of the filter plate 5. When the filter plate 5 swings downward, it causes the second fixing block 13 and the second connecting member 12 to rotate relative to each other. This causes the telescopic rod 23 and the connecting rod 11 to compress the spring 22. Simultaneously, the first connecting member 10 and the first fixing block 9 rotate relative to each other. After the impact force of rainwater and sewage is absorbed and buffered by the spring 22, the elastic force of the spring 22 causes the telescopic rod 23 to extend, and the filter plate 5 returns to its normal position to continue the rainwater and sewage separation process.

[0027] Example 2

[0028] like Figure 2 As shown in the figure, the rainwater and sewage diversion anti-backflow device proposed in this embodiment, compared with the first embodiment, has a collection tank 6 inside the box 1. The collection tank 6 is located below the bottom of the filter frame 3. The collection tank 6 and the side of the fixing plate 7 have a horizontal distance. The box 1 is equipped with a sewage suction pipe 19. One end of the sewage suction pipe 19 is located inside the collection tank 6. One end of the sewage suction pipe 19 extends out of the box 1 and the end extending out of the ground is connected to the sewage suction pump.

[0029] The interior of the box 1 is provided with a partition 16, the partition 16 is provided with a through hole 17, and the box 1 is provided with a drain pipe 18, which is located below the partition 16.

[0030] In this embodiment, the dirt will roll down along the filter frame 3 and filter plate 5 until it falls into the inside of the collection tank 6. The dirt in the collection tank 6 is then extracted by the suction pipe 19 and the suction pump. At the same time, the rainwater dripping from the filter plate 5 will enter the bottom of the box 1 through the through hole 17 on the partition plate 16, and then be discharged from the box 1 through the drain pipe 18.

[0031] Example 3

[0032] like Figure 1 As shown in the figure, the rainwater and sewage diversion anti-backflow device proposed in this embodiment, compared with the first embodiment, has a concrete base 20 on the box 1, and multiple steel columns 21 on the concrete base 20. The concrete base 20 is preset in the foundation pit, and the steel columns 21 are used to fix the concrete base 20. Then the box 1 can be placed on the concrete base 20 to ensure the stability of the box 1.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
