Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, specifically a foreign object interception device for urban sewage pipe discharge outlets. Background Technology

[0002] With the deepening of urbanization and the continuous improvement of industrialization in my country, the amount of wastewater discharged nationwide has shown a year-on-year increasing trend. In people's daily lives, activities such as washing, cooking, and cleaning generate a large amount of domestic sewage; simultaneously, under rain and snow conditions, surface runoff carries various pollutants, forming rainwater and sewage. To efficiently and centrally treat this sewage, a comprehensive sewage collection and transportation system must be established, among which sewage discharge pipelines have become an indispensable and important component of urban drainage systems. These pipelines not only need to have good transportation capacity but also need to consider characteristics such as corrosion resistance and leak prevention.

[0003] At the outlet of sewage pipes, specialized interception devices are usually installed. Their main function is to remove large amounts of solid pollutants carried in sewage through physical filtration. However, existing foreign object interception devices at sewage pipe outlets mostly use fixed-installation bar screens. These screens are typically composed of a series of parallel metal or plastic bars. As sewage continues to flow, the trapped debris accumulates in front of the screen, especially during periods of heavy rainfall or large discharges, easily causing blockages. Once a blockage occurs, it not only significantly reduces the flow capacity, leading to rising water levels and poor discharge, but may also cause localized water accumulation or even backflow. Therefore, this invention provides a foreign object interception device for urban sewage pipe outlets to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a foreign object interception device for urban sewage pipe discharge outlets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foreign object interception device for urban sewage pipe discharge outlets includes an interception box, a connecting pipe fixedly installed on the side of the interception box, a first interception plate and a second interception plate fixedly installed inside the interception box, a fixing rod fixedly installed on the surface of the second interception plate, a baffle fixedly installed on the side of the fixing rod, a cleaning component for removing large foreign objects from sewage provided inside the interception box, a collection box fixedly installed inside the interception box, a sealing door hinged to the surface of the collection box extending outside the interception box, a water leakage hole opened on the bottom surface of the collection box, a push plate slidably installed inside the collection box, a reset component for resetting the push plate inside the collection box, a partition fixedly installed inside the interception box, and a third interception plate fixedly installed on the top surface of the partition.

[0007] As a further embodiment of this utility model, the cleaning assembly includes a drive motor fixedly installed on the surface of the interception box. The output end of the drive motor extends through into the interior of the interception box and is fixedly installed with a first rotating shaft. A rotating rod is fixedly installed on the surface of the first rotating shaft, and a support plate is fixedly installed on the side of the rotating rod.

[0008] As a further embodiment of this utility model, the positions of the rotating rod and the fixed rod are staggered, and the positions of the support plate and the baffle are staggered.

[0009] As a further embodiment of this utility model, the reset assembly includes a fixed column fixedly installed inside the collection box. A spring groove is provided inside the fixed column, and a movable rod is slidably installed inside the spring groove. The movable rod is fixedly connected to a push plate. A movable block is fixedly installed at the end of the movable rod away from the push plate. A reset spring is fixedly installed on the side of the movable block near the movable rod, and the reset spring is sleeved on the surface of the movable rod.

[0010] As a further embodiment of this utility model, a first pulley is fixedly installed at the end of the first rotating shaft away from the drive motor, and a second rotating shaft is rotatably installed inside the interception box. A second pulley is fixedly installed at one end of the second rotating shaft, and a transmission belt connects the first pulley and the second pulley.

[0011] As a further embodiment of this utility model, an incomplete gear is fixedly mounted on the surface of the second rotating shaft, a rack is mounted on the side of the push plate near the incomplete gear, a pressure sensor is provided between the rack and the push plate, and the rack meshes with the incomplete gear.

[0012] As a further embodiment of this utility model, a sewage discharge pipe and an impurity discharge pipe are fixedly installed on the bottom surface of the interception box, and a top cover is connected to the top surface of the interception box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When this utility model is in use, the output end of the drive motor rotates, which drives the rotating rod to rotate and drives the support plate to rotate. This can lift the large foreign objects intercepted on the first intercepting plate and transport them into the collection box, preventing foreign objects from clogging the first intercepting plate. By setting the third intercepting plate, small foreign objects can be intercepted, thereby reducing the amount of foreign objects in the sewage.

[0015] 2. When this utility model is in use, as the first rotating shaft rotates, the second rotating shaft rotates under the transmission action of the transmission belt, which drives the incomplete gear to rotate, causing the rack to move and pushing the push plate to move. After the incomplete gear rotates one revolution, the teeth on the incomplete gear disengage from the rack, and the return spring pushes the push plate to return to its original position. This allows for repeated squeezing of foreign objects in the collection box, squeezing out the sewage adsorbed in the foreign objects. Attached Figure Description

[0022] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a foreign object interception device for urban sewage pipe outlets includes an interception box 1. A connecting pipe 2 is fixedly installed on the side of the interception box 1. A first interception plate 3 and a second interception plate 4 are fixedly installed inside the interception box 1 for intercepting foreign objects in sewage. The second interception plate 4 is fixedly connected to the first interception plate 3 and is inclined. Both the first interception plate 3 and the second interception plate 4 are provided with through holes. A fixing rod 6 is fixedly installed on the surface of the second interception plate 4, and multiple sets of fixing rods 6 are provided. A baffle 7 is fixedly installed on the side of the fixing rod 6, and multiple sets of baffles 7 are provided. A cleaning component for removing large foreign objects in sewage is provided inside the interception box 1. A collection box 12 is fixedly installed inside the interception box 1. A sealing door 13 is hinged to the surface of the collection box 12 extending to the outside of the interception box 1. By opening the sealing door 13, it is convenient to remove foreign objects from the collection box 12. The bottom surface of the collection box 12 is provided with a drainage hole 14 to facilitate the discharge of sewage from the collection box 12. A push plate 15 is slidably installed inside the collection box 12. To ensure that the push plate 15 can slide back and forth stably inside the collection box 12, sliders 16 are fixedly installed on both sides of the push plate 15. A groove 17 is provided inside the collection box 12, and the sliders 16 are slidably installed inside the groove 17. More specifically, the two ends of the sliders 16 are chamfered. The chamfered sliders 16 can easily remove foreign objects located in the groove 17. A reset component for resetting the push plate 15 is provided inside the collection box 12. A partition 30 is fixedly installed inside the interception box 1. A third interception plate 31 is fixedly installed on the top surface of the partition 30. A sewage discharge pipe 32 and a debris discharge pipe 33 are fixedly installed on the bottom surface of the interception box 1. A top cover 34 is connected to the top surface of the interception box 1.

[0024] like Figure 3 and Figure 4As shown, the cleaning assembly includes a drive motor 8 fixedly installed on the surface of the interception box 1. The output end of the drive motor 8 extends through into the interior of the interception box 1 and is fixedly installed with a first rotating shaft 9. A rotating rod 10 is fixedly installed on the surface of the first rotating shaft 9. Multiple sets of rotating rods 10 are provided. The positions of the rotating rods 10 and the fixed rods 6 are staggered. A support plate 11 is fixedly installed on the side of the rotating rods 10. Multiple sets of support plates 11 are provided. The positions of the support plates 11 and the baffles 7 are staggered. By driving the rotating rods 10 and the support plates 11 to rotate through the drive motor 8, the foreign objects intercepted by the first interception plate 3 can be picked up and sent into the collection box 12, which can prevent foreign objects from clogging the first interception plate 3 and enhance the water passage capacity.

[0025] like Figure 5 As shown, the reset assembly includes a fixed post 18 fixedly installed inside the collection box 12. A spring groove 19 is provided inside the fixed post 18. A movable rod 20 is slidably installed inside the spring groove 19. The movable rod 20 is fixedly connected to the push plate 15. A movable block 21 is fixedly installed at the end of the movable rod 20 away from the push plate 15. A reset spring 22 is fixedly installed on the side of the movable block 21 close to the movable rod 20. The reset spring 22 is sleeved on the surface of the movable rod 20.

[0026] A first pulley 25 is fixedly mounted on the end of the first rotating shaft 9 away from the drive motor 8. A second rotating shaft 26 is rotatably mounted inside the interception box 1. A second pulley 27 is fixedly mounted on one end of the second rotating shaft 26. A transmission belt 28 connects the first pulley 25 and the second pulley 27. A protective cover 5 is fixedly mounted on the surface of the interception box 1. The first pulley 25, the second pulley 27, and the transmission belt 28 are located inside the protective cover 5. The protective cover 5 can protect the first pulley 25, the second pulley 27, and the transmission belt. 28 is protected to prevent dust and rainwater from adhering and affecting the normal use of the transmission belt 28. An incomplete gear 29 is fixedly installed on the surface of the second rotating shaft 26. A rack 23 is installed on the side of the push plate 15 near the incomplete gear 29. A pressure sensor 24 is set between the rack 23 and the push plate 15. The rack 23 meshes with the incomplete gear 29. When the incomplete gear 29 disengages from the rack 23, the return spring 22 pushes the movable block 21, which in turn drives the push plate 15 to reset through the movable rod 20, preparing for the next extrusion operation.

[0027] The working principle of this utility model is as follows: In use, the interception box 1 is connected to the sewage outlet of the urban sewage pipe through the flange on the connecting pipe 2. Sewage from the sewage outlet enters the interception box 1 through the connecting pipe 2. The rotating rod 10 and the support plate 11 can intercept large foreign objects in the sewage. The drive motor 8 is started, and its output rotates, driving the first rotating shaft 9 to rotate, causing the rotating rod 10 to rotate, which in turn drives the support plate 11 to rotate. As the rotating rod 10 rotates counterclockwise, the foreign objects intercepted on the first interception plate 3 are lifted. After being lifted to the highest point, the foreign objects fall downwards onto the second interception plate 4 under the action of gravity. The second interception plate 4 is inclined, allowing the foreign objects to fall downwards onto the second interception plate 4. The debris continues to fall along the second interceptor plate 4 into the collection box 12. In addition, when the rotating rod 10 rotates to the vicinity of the second interceptor plate 4, the baffle 7 on the fixed rod 6 will clean the residual foreign objects attached to the rotating rod 10. Smaller foreign objects will pass through the first interceptor plate 3 and the second interceptor plate 4 and fall above the third interceptor plate 31. The diameter of the through hole on the third interceptor plate 31 is smaller than the diameter of the through hole on the first interceptor plate 3 and the second interceptor plate 4. Foreign objects in the sewage can be intercepted again by the third interceptor plate 31. The sewage that passes through the third interceptor plate 31 can be discharged through the sewage discharge pipe 32, and the foreign objects intercepted by the third interceptor plate 31 can be discharged by opening the impurity discharge pipe 33.

[0028] Simultaneously, as the first rotating shaft 9 rotates, it drives the first pulley 25 to rotate. Under the action of the transmission belt 28, the second pulley 27 rotates, which in turn drives the second rotating shaft 26 to rotate, causing the incomplete gear 29 to rotate. The incomplete gear 29 meshes with the rack 23. As the incomplete gear 29 rotates, it drives the rack 23 to move, which in turn pushes the push plate 15 to move. As the push plate 15 moves, it drives the movable rod 20 and the movable block 21 to move, causing the return spring 22 to compress. After the incomplete gear 29 rotates one revolution, the teeth on the incomplete gear 29 engage with the rack 23. When the toothed rod 23 disengages, the return spring 22 pushes the movable block 21 to move, causing the movable rod 20 and the push plate 15 to move, thus resetting the push plate 15. This allows for repeated squeezing of the foreign objects in the collection box 12, squeezing out the sewage adsorbed in the foreign objects. The squeezed-out sewage flows out of the collection box 12 through the drain hole 14. This design effectively squeezes out the sewage carried in the foreign objects, preventing sewage dripping during subsequent cleaning and removal of foreign objects, thereby avoiding secondary pollution. At the same time, the squeezing makes the foreign objects fit more tightly, allowing the collection box 12 to store more foreign objects. As the number of foreign objects in the collection box 12 increases, the force required for the push plate 15 to squeeze the foreign objects also increases. A pressure sensor 24 is installed between the toothed rod 23 and the push plate 15. When the pressure detected by the pressure sensor 24 exceeds the maximum set threshold, a signal is emitted. Upon receiving the signal, the external alarm sounds an alarm, reminding the staff that the number of foreign objects stored in the collection box 12 has reached its maximum. The staff can then remove the foreign objects from the collection box 12 for processing by opening the sealing door 13.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
