Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, and more specifically, to a municipal water conservancy drainage mechanism. Background Art

[0002] Municipal drainage pipes refer to the rainwater and sewage pipes under municipal roads, which are usually called municipal drainage pipes in engineering. According to the current status of facilities under China's municipal roads, different pipelines are generally installed, such as electricity, communications, gas, water supply, drainage pipes, etc., and drainage pipes take into account the measures of rainwater and sewage separation, that is, rainwater is generally discharged into the nearest river, and sewage is discharged into the sewage treatment plant, so municipal drainage pipes include both rainwater and sewage pipes.

[0003] The existing municipal road anti-blocking drainage machine uses a connecting rod to drive the collection frame to move upward and remove the debris in the collection frame. In order to ensure the water flow capacity, the mesh of the collection frame is designed to have a certain size, which makes it easy for mud and sand to pass through the filter screen. Therefore, the bottom walls of the two pipe grooves are prone to sedimentation and the mud and sand are not easy to clean.

[0004] After searching, the municipal water conservancy drainage mechanism disclosed in the Chinese patent with announcement number CN221001315U is found. The utility model is provided with a sedimentation box at the bottom of the sewage collecting trough, and the sludge is settled through the sedimentation box. By setting the bottom surface of the drainage trough as an inclined surface, the sludge is not easy to accumulate in the drainage trough, and the bottom walls of the drainage trough and the sewage collecting trough are not easy to settle silt. By removing the sedimentation box, the silt is more convenient to clean.

[0005] However, when the above drainage mechanism is actually used, when too many impurities accumulate on the surface of the filter plate, the filtering effect of the filter plate on sewage will be reduced. After a certain period of accumulation, the risk of drainage pipe blockage will be greatly increased. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a municipal water conservancy drainage mechanism to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The cleaning mechanism of claim 1, wherein the outer side of the filter plate is fixedly connected to the inner wall of the protective shell, and one side of the filter plate is fixedly connected to three brackets. The upper surface of the filter plate is fixedly connected to three guide rails. A liquid storage tank is provided on one side of the filter plate, the outer side of the liquid storage tank is fixedly connected to the inner wall of the protective shell, and the inner wall of the liquid storage tank is fixedly connected to two slot plates. The slot plate is slidably connected to a guide rod, one side of the guide rod is fixedly connected to a floating plate, the top of the floating plate is fixedly connected to three movable seats, the outer side of the movable seat is rotatably connected to a push rod, the outer side of the push rod is provided with a slide groove, and the bottom of the floating plate is provided with a cavity, the tops of the three push rods are rotatably connected to a transmission frame, the three transmission frames are evenly distributed on the top of the floating plate, one side of the transmission frame is rotatably connected to a slider, and the outer side of the slider is fixedly connected to the push plate.

[0009] By adopting the above technical solution: the sewage flowing into the liquid storage tank provides buoyancy to the float plate, so that the float plate can drive the transmission frame, slider and push plate to clean the impurities accumulated on the surface of the filter plate, avoiding the accumulation of impurities on the surface of the filter plate, and improving the drainage mechanism's filtering efficiency for impurities.

[0010] As a further description of the above technical solution: three positioning blocks are fixedly connected to the bottom of the liquid storage box, and the three positioning blocks are evenly distributed on the lower surface of the liquid storage box. A sealing plate is hinged at the bottom of the liquid storage box, and a telescopic rod is installed inside the positioning block, and a rubber composite spring is provided inside the telescopic rod.

[0011] By adopting the above technical solution, the sewage inside the liquid storage tank can be discharged in time, and at the same time, the telescopic rod is pushed by three rubber composite springs to slowly reset, so that the sewage inside the push plate can be discharged downward in time, and the floating plate can move up and down inside the liquid storage tank, so that the push plate can reciprocate and clean the filter plate.

[0012] As a further description of the above technical solution: an installation and collection mechanism is provided inside the protective shell, and the installation and collection mechanism includes two guide plates, the outer sides of the guide plates are slidingly connected to the inner walls of the protective shell, and two pull rods are fixedly connected to the top of the guide plates. An external frame is fixedly connected to the inside of the protective shell, and a collection frame is slidingly connected to the inside of the external frame. A cover plate is installed on the top of the protective shell.

[0013] By adopting the above technical solution, the pull rod and the collection frame can be quickly disassembled and assembled, which makes it easy to clean impurities inside the collection frame and improves work efficiency.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. By setting up a cleaning mechanism, compared with the existing technology, the sewage can be double-filtered to prevent impurities from falling into the drain and causing clogging of the drain. At the same time, the surface of the filter plate can be automatically cleaned back and forth to avoid excessive accumulation of impurities on the surface of the filter plate, thereby improving the filtering effect of the drainage mechanism and extending its service life.

[0016] 2. By setting up and installing a collection mechanism, compared with the existing technology, impurities inside the protective shell can be collected through an external frame and a collection frame, and the impurities can be filtered at the same time to avoid sewage being mixed in the magazine, making it easier for subsequent staff to remove the pull rod and the collection frame from the inside of the protective shell for cleaning, thereby improving the cleaning efficiency of the drainage mechanism.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The embodiment of the present application discloses a municipal water conservancy drainage mechanism, including a protective shell 1, a cleaning mechanism is provided inside the protective shell 1; the cleaning mechanism includes a filter plate 2, the outer side of the filter plate 2 is fixedly connected to the inner wall of the protective shell 1, one side of the filter plate 2 is fixedly connected to three brackets 3, the upper surface of the filter plate 2 is fixedly connected to three guide rails 4, a liquid storage box 5 is provided on one side of the filter plate 2, the outer side of the liquid storage box 5 is fixedly connected to the inner wall of the protective shell 1, the inner wall of the liquid storage box 5 is fixedly connected to two groove plates 6, the groove plate 6 is slidably connected to a guide rod 7, one side of the guide rod 7 is fixedly connected to a floating plate 8, the top of the floating plate 8 is fixedly connected to three movable seats 9, the outer side of the movable seat 9 is rotatably connected to a push rod 10, the outer side of the push rod 10 is provided with a slide groove 11, and the floating plate A cavity 12 is provided at the bottom of 8, and the tops of the three push rods 10 are rotatably connected to a transmission frame 13. The three transmission frames 13 are evenly distributed on the top of the floating plate 8. One side of the transmission frame 13 is rotatably connected to a slider 14, and a push plate 15 is fixedly connected to the outside of the slider 14. The sewage is filtered through the filter plate 2, so that the impurities remain on the top of the filter plate 2. Later, when too many impurities remain on the top of the filter plate 2, the sewage flows into the inside of the liquid storage tank 5, and the buoyancy of the water causes the floating plate 8 to drive the push rod 10 to move upward. Through the guidance of the bracket 3, the push rod 10 can push the transmission frame 13, the slider 14 and the push plate 15 to move on the top of the filter plate 2, so that the impurities accumulated on the top of the filter plate 2 can be pushed out from one side of the filter plate 2.

[0028] Reference Figure 7 As shown, three positioning blocks 16 are fixedly connected to the bottom of the liquid storage box 5, and the three positioning blocks 16 are evenly distributed on the lower surface of the liquid storage box 5. A sealing plate 24 is hinged at the bottom of the liquid storage box 5, and a telescopic rod 17 is installed inside the positioning block 16. A rubber composite spring 18 is provided inside the telescopic rod 17. When too much sewage accumulates inside the liquid storage box 5, the sewage will push the sealing plate 24 downward and away from the bottom of the liquid storage box 5, so that the sewage can be discharged from the bottom of the liquid storage box 5. Then, the rubber composite spring 18 pushes the telescopic rod 17 to push the sealing plate 24 upward, so that the sealing plate 24 re-seals the liquid storage box 5, so that the liquid storage box 5 can re-store water, which facilitates the reciprocating movement of the floating plate 8, so that the push plate 15 can reciprocate and clean the top of the filter plate 2.

[0029] Reference Figure 1 and Figure 8As shown, the protective shell 1 is provided with an installation collection mechanism, which includes two guide plates 19. The outer side of the guide plate 19 is slidably connected to the inner wall of the protective shell 1. Two pull rods 20 are fixedly connected to the top of the guide plate 19. An external frame 21 is fixedly connected to the inside of the protective shell 1. A collection frame 22 is slidably connected to the inside of the external frame 21. A cover plate 23 is installed on the top of the protective shell 1. By opening the cover plate 23, the guide plate 19 and the collection frame 22 can be quickly removed from the inside of the protective shell 1, so as to facilitate the cleaning of the accumulated impurities inside the collection frame 22.

[0030] The working principle of the utility model is as follows: when the water conservancy drainage mechanism is installed, the protective shell 1 is first placed in the drainage hole dug in advance, and then the outer side of the protective shell 1 is buried, and the cover plate 23 is covered on the top of the protective shell 1. The drainage mechanism is used. When the sewage passes through the cover plate 23 and enters the interior of the protective shell 1, the larger impurities are isolated outside by the cover plate 23, and the smaller impurities are guided by the two guide plates 19 with the water flow and fall into the top of the filter plate 2. The sewage and impurities are filtered by the filter plate 2, so that the sewage falls downward into the drainage ditch through the filter plate 2. The impurities accumulate on the top of the filter plate 2. When the impurities on the top of the filter plate 2 accumulate to a certain thickness, the sewage will pass through the filter plate 2 and the impurities. The inclined surface falls into the interior of the liquid storage tank 5. When the sewage accumulates to a certain height inside the liquid storage tank 5, the floating plate 8 has a strong buoyancy when passing through the three cavities 12 at the bottom. The floating plate 8 is guided by the two groove plates 6 to keep the floating plate 8 moving upward steadily. Then the floating plate 8 drives the push rod 10 on the top to rise through the movable seat 9. The push rod 10 is guided by the slide groove 11 and the bracket 3, so that the push rod 10 can push the transmission frame 13 and the slider 14 to move along the three guide rails 4 on the top of the filter plate 2. The slider 14 then drives the push plate 15 to clean the impurities accumulated on the surface of the filter plate 2, so that the impurities pass through one side of the filter plate 2 and fall into the interior of the collection frame 22 for collection.

[0031] After that, when the sewage inside the liquid storage box 5 reaches a certain height, the water pressure will push the sealing plate 24 downward, so that the sealing plate 24 separates from the bottom of the liquid storage box 5, and the sewage inside the liquid storage box 5 can flow downward. Then, the three rubber composite springs 18 push the three telescopic rods 17 to move upward slowly. When the telescopic rods 17 push the sealing plate 24 to close the liquid storage box 5 again, the sewage inside the liquid storage box 5 has been discharged, so that the floating plate 8 drives the push rod 10 and the slider 14 to move backward, which is convenient for the subsequent cleaning of accumulated impurities.

[0032] Afterwards, the cover plate 23 is opened, and the guide plate 19 and the external frame 21 can be taken out from the interior of the protective shell 1 to facilitate cleaning of impurities inside the external frame 21 .

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
