Description

Technical Field

[0001] The utility model relates to the technical field of river pollution control equipment, in particular to a sewage cleaning and diversion device for urban combined sewers. Background Art

[0002] A combined sewer is a drainage system that uses the same pipe system to collect and convey domestic sewage, industrial wastewater, and rainwater. It can be divided into a direct discharge combined sewer system and an intercepted combined sewer system according to different disposal methods after the sewage, wastewater, and precipitation runoff are collected. Discharging the mixed sewage directly into the nearby water body through the traditional urban combined sewer will seriously pollute the water body. Now, the urban combined sewer uses a diversion device to divert the sewage to the sewage treatment plant, which can avoid directly discharging and polluting the nearby water body. However, a large amount of garbage is mixed in the sewage, and the garbage is easy to accumulate in the diversion device, and it is necessary for workers to enter for regular cleaning, which makes the workload of the workers large and not convenient for cleaning. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a sewage cleaning and diversion device for urban combined sewers. The cleaning box can separate the sewage discharged from the water inlet pipe into the confluence well from the garbage, and make the garbage accumulate in the cleaning box. When it is necessary to clean the garbage in the cleaning box, the servo motor can drive the traction belt to move upward, so that the cleaning box moves upward to the wellhead position of the confluence well. Workers can clean the garbage in the cleaning box without entering the confluence well, which is convenient for cleaning work and reduces the workload of workers.

Detailed Embodiments

[0015] The following is a further description of the utility model in conjunction with the drawings and specific embodiments, so as to more clearly understand the technical idea to be protected by the utility model.

[0016] As Figures 1 to 3 shown, a sewage cleaning and diversion device for urban combined sewers includes a confluence well 1, a water inlet pipe 2, a water outlet pipe 3, an intercepting pipe 4, a dirt cleaning box 5 and a servo motor 6. The water inlet pipe 2, the water outlet pipe 3 and the intercepting pipe 4 are respectively communicated with the confluence well 1. The dirt cleaning box 5 is slidably connected to the confluence well 1 and can be communicated with the water inlet pipe 2. Two servo motors 6 are arranged on the front and rear sides of the wellhead on the top surface of the confluence well 1, and the output ends of the two servo motors 6 are connected to the dirt cleaning box 5 through a traction belt 7. A conveying roller 8 for supporting and tensioning the traction belt 7 is arranged at the wellhead on the top surface of the confluence well 1.

[0017] The working principle of the urban combined sewer cleaning and flow diversion device described in the present utility model is achieved through the mutual cooperation of the confluence well 1, the inlet pipe 2, the outlet pipe 3, the intercepting pipe 4, the cleaning box 5 and the servo motor 6. As Figures 1 to 3 shown, sewage enters the confluence well 1 along the drain pipe, and the sewage discharge box filters the garbage in the sewage and blocks the garbage in the cleaning box 5. When it is necessary to clean the garbage in the cleaning box 5, the servo motor 6 can drive the traction belt 7 to move upward, and the conveying roller 8 supports and tensions the traction belt 7, so that the cleaning box 5 moves upward to the wellhead position of the confluence well 1, so as to facilitate the staff to clean the garbage in the cleaning box 5. After the garbage in the cleaning box 5 is cleaned, the servo motor 6 puts the cleaning box 5 back into the confluence well 1 through the traction belt 7. In this way, the staff does not need to enter the confluence well 1 to clean the cleaning box 5. Compared with the traditional combined sewer flow diversion device, the cleaning box 5 of the urban combined sewer cleaning and flow diversion device can separate the sewage and garbage discharged from the inlet pipe 2 into the confluence well 1, and make the garbage accumulate in the cleaning box 5, and the staff does not need to enter the confluence well 1 to clean the garbage in the cleaning box 5, which is convenient for cleaning work and reduces the workload of the staff entering and leaving the confluence well 1.

[0018] Specifically, the inlet pipe 2 is communicated with the left side of the confluence well 1, the outlet pipe 3 is communicated with the right side of the confluence well 1, and the intercepting pipe 4 is communicated with the rear side of the confluence well 1. Among them, an overflow plate 9 is arranged at the right side position of the pipe orifice of the intercepting pipe 4 on the bottom surface of the confluence well 1, and the height of the overflow plate 9 is greater than the height of the pipe orifice of the outlet pipe 3. Among them, a cover 10 is arranged at the wellhead position of the confluence well 1, and through grooves 11 for the traction belt 7 to pass through are arranged at the front and rear side positions of the cover 10, and a handle groove 12 is arranged at the center of the cover 10. As Figures 1 to 3 shown, the cover 10 closing the confluence well 1 can reduce the outward diffusion of the odor of the garbage, and the through groove 11 can prevent the cover 10 from squeezing the traction belt 7 and causing the traction belt 7 to wear. The staff can hold the handle groove 12 and lift the cover 10 vertically upward, so that the servo motor 6 can move the cleaning box 5 to the top of the confluence well 1 through the traction belt 7 for cleaning work. On sunny days, the amount of water discharged from the inlet pipe 2 into the confluence well 1 is small, and the water level height in the confluence well 1 is lower than the overflow plate 9, and the sewage is discharged from the intercepting pipe 4 out of the confluence well 1. On rainy days, the amount of water discharged from the inlet pipe 2 into the confluence well 1 increases. If the water level height in the confluence well 1 is higher than the overflow plate 9, the sewage can be discharged from the confluence well 1 along the outlet pipe 3, so as to divert the sewage and control the water level height in the confluence well 1.

[0019] Further, a slide rail 13 is provided above the water inlet pipe 2 in the confluence well 1. Slide grooves 14 are provided on the left side of the top surface and the left side of the bottom surface of the sewage cleaning box 5, and the slide grooves 14 of the sewage cleaning box 5 are slidably connected to the slide rail 13 of the confluence well 1. Further still, a filter screen layer 15 is provided on the side wall of the sewage cleaning box 5, and the side of the sewage cleaning box 5 facing the water inlet pipe 2 is an open structure. As Figures 1 to 3 shown, the sewage discharged from the drain pipe into the confluence pipe passes through the sewage cleaning box 5, and the filter screen layer 15 of the sewage cleaning box 5 can filter the sewage and block the garbage in the sewage cleaning box 5. The sewage cleaning box 5 can move upward along the slide rail 13 to the top of the confluence well 1 to facilitate the cleaning of the garbage in the sewage cleaning box 5, which has a guiding effect.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
