Description

Technical Field

[0001] This utility model relates to the field of rainwater pipe purification and treatment, and in particular to an end interception structure for rainwater pipes. Background Technology

[0002] Urban residents' domestic sewage, as well as the large volumes of wastewater discharged from government agencies, schools, hospitals, commercial service institutions, and various public facilities, are currently discharged after simple filtration. This results in inadequate sewage treatment. Oily contaminants in the sewage can form an oil film on the water surface, isolating the water from the atmosphere and disrupting the oxygen-rich conditions of the water body. The reduction in dissolved oxygen causes plankton to suffocate and die due to lack of oxygen; it also restricts the photosynthesis of algae and other aquatic plants, affecting the water body's self-purification function and even causing water quality deterioration and foul odors. Fish, shrimp, shellfish, and other aquatic plants and animals contaminated by oily wastewater will develop unpleasant odors. Toxic and harmful substances, accumulated by fish and shellfish, will harm human health through the food chain, causing serious environmental pollution. Furthermore, centralized sewage treatment is extremely expensive.

[0003] For example, a Chinese patent with patent number CN215946923U discloses a non-powered suspended solids interceptor; the cited document can effectively filter pollutants in water, is relatively environmentally friendly, can adjust the length of the device according to usage needs, is suitable for different working occasions, facilitates the replacement of internal parts, and makes it easy to clean the sludge inside the device.

[0004] While the aforementioned cited patent achieves the filtration of rainwater and oil stains in actual use, it still has certain limitations. Specifically, the inspection port in the document is exposed, which makes it easy for debris such as garbage, fallen leaves, and mud to enter, increasing the pollution burden inside the lower casing and affecting the normal operation and filtration effect of the equipment. At the same time, when it is open, rainwater may directly rush in and stir up the sediment, leading to a decrease in filtration effect.

[0005] Therefore, an end-of-pipe interception structure for rainwater pipes is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an end interception structure for rainwater pipes, which can effectively block the inspection port, improve the interception effect of rainwater pipes, and help improve maintenance efficiency and reduce downtime.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] An end-of-pipe interception structure for rainwater pipes includes several lower shells and several upper shells; each of the lower shells and upper shells is a rectangular base structure; each of the lower shells and upper shells corresponds to each other and is arranged vertically opposite each other;

[0009] The lower housing and the upper housing are interconnected and have a rectangular mounting cavity inside, and a filter box is mounted in the rectangular mounting cavity.

[0010] Water inlet grooves are formed on the sides of the lower and upper shells located at the head, and drainage grooves are formed on the lower and upper shells located at the tail.

[0011] A support bracket is vertically formed between two adjacent lower shells. The filter box is supported on the upper surface of several support brackets. The filter box is constructed from several plates with mesh.

[0012] Each of the upper housings is provided with an inspection port, and the bottom of the filter box is provided with several cleaning ports spaced laterally along its side. Each cleaning port is provided with a cover plate on one side.

[0013] Two sets of mounting structures are installed on the inner wall of each of the upper housings. An impurity interception frame is detachably installed between the two sets of mounting structures. The impurity interception frame is located at the bottom of the inspection port and fits against the inspection port.

[0014] Furthermore, the mounting structure includes a mounting plate disposed on the inner wall of the upper housing and located at the bottom of the inspection port. A sliding groove is provided on the side of the mounting plate, and a cross slider is slidably disposed in the sliding groove. A sliding block is connected to the bottom of the cross slider.

[0015] Furthermore, a fixed block is also installed on the side of the mounting plate; the sliding block and the fixed block are arranged opposite each other and both have clamping notches on their opposite sides.

[0016] Furthermore, the impurity interception frame is stepped on both sides and is respectively positioned between the sliding block and the fixed block within one set of mounting structures.

[0017] Furthermore, the slide groove is closed on both sides and a threaded screw is rotatably installed inside it. The threaded screw passes through the sliding block and engages with its threads.

[0018] Furthermore, one end of the threaded screw passes through the slide groove and extends to the bottom of the mounting plate, where a rotating handle is connected.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This structure is based on the synergistic effect of multiple lower and upper shells. Rainwater enters the pipe from the inlet trough and undergoes preliminary filtration through the filter box to remove larger suspended solids and impurities. Through the cooperation of the filter box and the sludge removal port assembly, suspended solids, silt, and other impurities in rainwater or sewage can be effectively filtered, ensuring the cleanliness of the drainage water. Through stratified filtration and sedimentation, the impact of large particles in the water on downstream water quality is reduced.

[0021] 2. With the addition of inspection and cleaning ports, users can easily clean the filter box and sediment. The quick-release design between the impurity interception frame and the installation structure allows for rapid installation or removal when needed, improving maintenance efficiency and reducing downtime. Furthermore, the tight fit between the impurity interception frame and the bottom of the inspection port effectively prevents external impurities from entering the pipeline.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] First embodiment;

[0030] Reference Figure 1-4 As shown, a preferred embodiment of the present invention is a rainwater pipe end interception structure, including a plurality of lower shells 1 and a plurality of upper shells 2; the plurality of lower shells 1 and upper shells 2 are all rectangular base structures; each lower shell 1 and upper shell 2 corresponds to each other and is arranged in an up-down opposition;

[0031] Several lower housings 1 and several upper housings 2 are interconnected and form a rectangular mounting cavity inside, and a filter box 6 is mounted inside the rectangular mounting cavity.

[0032] Water inlet grooves 3 are formed on the sides of the lower shell 1 and upper shell 2 located at the head, and drainage grooves 4 are formed on the lower shell 1 and upper shell 2 located at the tail.

[0033] A support bracket 11 is vertically formed between two adjacent lower shells 1. The filter box 6 is supported and set on the upper surface of several support brackets 11. The filter box 6 is constructed from several plates with mesh.

[0034] Each upper housing 2 has an inspection port 5, and the bottom of the filter box 6 has several cleaning ports 7 spaced laterally. Each cleaning port 7 has a cover plate 61 rotatably installed on one side.

[0035] Two sets of mounting structures 8 are installed on the inner wall of each upper housing 2. An impurity interception frame 9 is detachably installed between the two sets of mounting structures 8. The impurity interception frame 9 is located at the bottom of the inspection port 5 and fits against the inspection port 5.

[0036] In this embodiment, the structure is based on the synergistic effect between multiple lower housings 1 and upper housings 2. Rainwater enters the pipe from the inlet trough 3 and undergoes preliminary filtration through the filter box 6 to remove larger suspended solids and impurities. Through the cooperation of the filter box 6 and the sludge removal port 7 assembly, suspended solids, silt, and other impurities in rainwater or sewage can be effectively filtered, ensuring the cleanliness of the drainage water. Through stratified filtration and sedimentation, the impact of large particles in the water on downstream water quality is reduced.

[0037] Furthermore, by providing the inspection port 5 and the sludge removal port 7, users can easily clean the filter box 6 and the sediment. The quick-release design between the impurity interception frame 9 and the mounting structure 8 allows for rapid installation or removal of the impurity interception frame 9 when needed, which helps improve maintenance efficiency and reduce downtime. At the same time, the tight fit between the impurity interception frame 9 and the bottom of the inspection port 5 effectively prevents external impurities from entering the pipeline.

[0038] Second embodiment;

[0039] Reference Figure 3-4As shown, the mounting structure 8 includes a mounting plate 81 disposed on the inner wall of the upper housing 2 and located at the bottom of the inspection port 5. A groove 82 is provided on the side of the mounting plate 81, and a cross slider 83 is slidably disposed in the groove 82. A sliding block 84 is connected to the bottom of the cross slider 83.

[0040] In this embodiment, the sliding block 84 and the fixed block 85 are used to clamp and install the impurity interception frame 9.

[0041] Third embodiment;

[0042] Reference Figure 3-4 As shown, a fixed block 85 is also installed on the side of the mounting plate 81; the sliding block 84 and the fixed block 85 are arranged opposite each other and both have clamping notches 86 on their opposite sides.

[0043] In this embodiment, and in the preferred embodiment, by opening a clamping notch 86 on the opposite side of the sliding block 84 and the fixed block 85, the stepped impurity interception frame 9 can be firmly inserted into it, forming a tightly fitted whole, which can improve the clamping stability of the impurity interception frame 9.

[0044] Fourth embodiment;

[0045] Reference Figure 3-4 As shown, the impurity interception frame 9 is stepped on both sides and is respectively located between the sliding block 84 and the fixed block 85 in one of the mounting structures 8.

[0046] In this embodiment, the sliding block 84 moves within the mounting plate 81 via the sliding groove 82, and is adjustable, allowing the position and tightness of the impurity interception frame 9 to be adjusted as needed. When the sliding block 84 is aligned with one side of the stepped impurity interception frame 9, its position can be controlled by the threaded screw 87, ensuring that the impurity interception frame 9 is accurately and securely installed at the bottom of the inspection port 5.

[0047] Furthermore, the stepped structure on both sides of the impurity interception frame 9 allows it to form a firm fit with the sliding block 84 and the fixed block 85 in the mounting structure 8. The fixed block 85 and the sliding block 84 form a relative clamping action, clamping the other side of the impurity interception frame 9. This design enhances the sealing and stability between the interception frame 9 and the mounting structure 8, preventing loosening or falling off that may occur during the cleaning process.

[0048] Fifth embodiment;

[0049] Reference Figure 3-4 As shown, the slide groove 82 is closed on both sides and a threaded screw 87 is rotatably installed inside it. The threaded screw 87 passes through the sliding block 84 and engages with it by thread.

[0050] In this embodiment, the threaded screw 87 can be used to adjust the position of the sliding block 84. In use, the sliding block 84 limits the linear movement of the cross slider 83. When the threaded screw 87 is rotating in both directions, the cross slider 83, which is engaged with the outside of the threaded screw 87, can move in a reciprocating linear motion along the stroke range of the threaded screw 87.

[0051] Sixth embodiment;

[0052] Reference Figure 3-4 As shown, one end of the threaded screw 87 passes through the slide groove 82 and extends to the bottom of the mounting plate 81, where a rotating handle 88 is connected.

[0053] In this embodiment, the provided rotating handle 88 can be used to control the rotation of the threaded screw 87.

[0054] Furthermore, in a preferred embodiment, the threaded screw 87 is made of stainless steel.

[0055] Specific implementation process:

[0056] Step 1: By attaching the upper housing 2 to the upper end of the lower housing 1, and connecting adjacent lower housing 1 and upper housing 2 with bolts and mounting plates, the entire lower housing 1 is then buried in the pre-reserved underground pit. The inlet trough 3 is connected to the inlet pipe, and the drainage trough 4 is connected to the drainage pipe. The working principle of this rainwater pipe end interception structure is based on the synergistic effect between multiple lower housings 1 and upper housings 2. Rainwater enters the pipe from the inlet trough 3 and undergoes preliminary filtration through the filter box 6, removing larger suspended solids and impurities. Throughout the process, the filter box 6 effectively intercepts large particles of impurities in the water through its mesh plate. After the water flows through the filter box 6, smaller suspended solids such as silt are further removed through guidance and sedimentation. If the water volume is large, the water flows out through the end drainage trough 4 to avoid system overload. Simultaneously, the equipment can be regularly cleaned through the sludge removal port 7 and the cover plate 61 to ensure the long-term efficient operation of the system.

[0057] Step 2: To improve the maintainability and filtration efficiency of the equipment, the structure is designed with several convenient maintenance functions. The upper housing 2 has an inspection port 5 for easy inspection and cleaning of the internal filter box 6. The bottom of the inspection port 5 is equipped with a removable impurity interception frame 9, which can be quickly installed or removed via the mounting structure 8. The impurity interception frame 9 effectively intercepts impurities entering the inspection port, preventing them from affecting the cleanliness of the system's internal components.
