Description

Technical Field

[0001] This utility model relates to the field of rainwater well technology, and in particular to a foreign object interception mechanism for rainwater wells. Background Technology

[0002] In urban drainage systems, storm drains play a crucial role, serving as key facilities for collecting and discharging rainwater. With the acceleration of urbanization, the demand for rainwater drainage in urban roads, squares, and other areas is increasing, placing higher demands on the performance of storm drains.

[0003] However, existing storm drains have some problems in actual use. They are usually equipped with filters to block foreign objects and prevent blockages. However, in actual use, foreign objects tend to spread on the filters, which, even if not many, can significantly affect drainage, reduce drainage efficiency, cause urban flooding, and disrupt traffic and residents' lives. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a foreign object interception mechanism for rainwater wells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foreign object interception mechanism for a rainwater well includes a housing. Trapezoidal blocks are fixedly connected to both sides of the inner wall of the housing near the top. An interception frame is slidably disposed on the top of the inner wall of the housing and is adapted to the trapezoidal blocks. The bottom sides of the interception frame are provided with inclined surfaces, and a rectangular hole is opened in the middle of the bottom of the interception frame. A collection frame is slidably disposed in the middle of the rectangular hole, and a square frame is fixedly connected to the top of the collection frame. Handles are fixedly connected to both ends of the top of the square frame. A seepage hole is opened at the bottom of the collection frame, and multiple strip holes are opened on both sides of the bottom of the interception frame.

[0007] Preferably, sliding rods are fixedly connected to both sides of the bottom of the outer wall of the interception frame, and protrusions are fixedly connected to the bottom of the four sliding rods. The same lifting plate is slidably sleeved on the circumferential surface of the two sliding rods at the same end, and sliding sleeves adapted to the sliding rods are fixedly sleeved at both ends of the two lifting plates.

[0008] Preferably, multiple triangular frames are fixedly connected at equal distances to the top of the two lifting plates. Each triangular frame is adapted to a corresponding strip hole. By raising and lowering the triangular frames, foreign objects on both sides of the interception frame can be easily moved to the collection frame.

[0009] Preferably, a U-shaped rod is fixedly connected to the bottom of each of the two lifting plates, and the same clamp is fixedly connected between the two U-shaped rods, with a float fixedly connected to the middle of the clamp.

[0010] Preferably, a fixing block is fixedly connected to both ends of the bottom of the outer shell, a water collection tank is provided at the bottom of the outer shell, and a connecting block is fixedly connected to both ends of the outer wall of the water collection tank. Each connecting block is connected to the nearest fixing block by bolts. The setting of the connecting blocks and fixing blocks facilitates the disassembly and maintenance of the water collection tank.

[0011] Preferably, three siphon tubes are fixedly fitted at equal intervals on the bottom of the inner wall of the water collection tank near one side. The water collection tank has round holes that are adapted to the siphon tubes, and the top of each water collection tank is located inside the water collection tank. The siphon tubes can automatically discharge water when the water level inside the water collection tank is full.

[0012] Preferably, two fixing holes are provided on both sides of the top of the outer casing, which facilitates fixing the outer casing.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing technologies such as interception frames, sliding rods, triangular frame floats, water collection tanks, and siphon pipes, the design of the interception frame allows foreign objects to easily accumulate in the central collection frame. Changes in the water level inside the collection tank cause the floats to rise and fall, allowing the triangular frame to move foreign objects from both sides of the interception frame towards the center. This ensures normal drainage on both sides of the interception frame, effectively solving the problem of low drainage efficiency in rainwater wells mentioned in the background technology. It achieves efficient interception and centralized collection of foreign objects carried by rainwater, concentrating them in the center to ensure continuous and smooth drainage from both sides, reducing the risk of urban flooding and preventing them from entering drainage pipes and causing blockages. This significantly improves the long-term drainage efficiency and stability of rainwater wells. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A foreign object interception mechanism for a rainwater well includes a housing 1. Trapezoidal blocks 101 are fixedly connected to both sides of the inner wall of the housing 1 near the top. An interception frame 3 is slidably disposed on the top of the inner wall of the housing 1, and the interception frame 3 is adapted to the trapezoidal blocks 101. The bottom sides of the interception frame 3 are provided with inclined surfaces, and a rectangular hole 301 is opened in the middle of the bottom of the interception frame 3. A collection frame 304 is slidably disposed in the middle of the rectangular hole 301, and a square frame 303 is fixedly connected to the top of the collection frame 304. Handles 305 are fixedly connected to both ends of the top of the square frame 303. A seepage hole is opened at the bottom of the collection frame 304. Multiple strip holes 302 are opened on both sides of the bottom of the interception frame 3. By pulling the handles 305, the square frame 303, the collection frame 304 and the interception frame 3 are separated, making it convenient for the user to handle foreign objects.

[0022] In this utility model, slide rods 4 are fixedly connected to both sides of the bottom of the outer wall of the interception frame 3. The bottom of the four slide rods 4 are fixedly connected to protrusions. The same lifting plate 401 is slidably sleeved on the circumferential surface of the two slide rods 4 at the same end. The two ends of the two lifting plates 401 are fixedly sleeved with sliding sleeves that are compatible with the slide rods 4. The sliding sleeves can ensure that the lifting plate 401 can be stably raised and lowered on the slide rods 4.

[0023] In this utility model, multiple triangular frames 402 are fixedly connected at equal distances to the top of the two lifting plates 401. Each triangular frame 402 is adapted to the corresponding strip hole 302. By lifting the triangular frame 402, foreign objects on both sides of the interception frame 3 can easily enter the collection frame 304.

[0024] In this utility model, a U-shaped rod 403 is fixedly connected to the bottom of each of the two lifting plates 401. The same clamp 404 is fixedly connected between the two U-shaped rods 403, and a float 405 is fixedly connected to the middle of the clamp 404. By raising the float 405, the lifting plates 401 and the triangular frame 402 can be raised, so that the triangular frame 402 passes through the strip hole 302, and the foreign object at the strip hole 302 tilts and falls into the collection frame 304.

[0025] In this utility model, fixing blocks 102 are fixedly connected to both ends of the bottom sides of the outer shell 1. A water collection tank 2 is provided at the bottom of the outer shell 1. Connecting blocks 201 are fixedly connected to both ends of the outer walls of the water collection tank 2. Each connecting block 201 is connected to the nearest fixing block 102 by bolts. Through the cooperation between the connecting blocks 201 and the fixing blocks 102, maintenance personnel can easily disassemble and maintain the water collection tank 2.

[0026] In this utility model, three siphon pipes 202 are fixedly sleeved at equal intervals on the bottom of the inner wall of the water collection tank 2 near one side. The water collection tank 2 has a round hole that matches the siphon pipes 202. The top of each water collection tank 2 is located inside the water collection tank 2. The arrangement of the three siphon pipes 202 allows the water inside the water collection tank 2 to be automatically discharged when the water level is full, causing the float 405 to descend.

[0027] In this utility model, two fixing holes 103 are provided on both sides of the top of the outer shell 1. The fixing holes 103 facilitate fixing to the inside of the rainwater well by means of expansion screws.

[0028] Working principle: When in use, this mechanism is first fixed to the top of the inner wall of the rainwater well using expansion screws and fixing holes 103. Then, the water collection tank 2 is fixed to the fixing block 102 via connecting block 201 using bolts. Next, the intercepting frame 3 is inserted into the outer shell 1. The trapezoidal stop block 101 limits the intercepting frame 3, preventing it from sliding down. After resetting the top cover of the rainwater well, it is ready for use. When foreign objects enter the rainwater well, they will remain on top of the intercepting frame 3. Due to the tilt of the intercepting frame 3 on both sides, the foreign objects are generally collected in the collection frame 304. The bottom of the collection frame 304 has seepage holes to prevent water accumulation inside. Simultaneously, multiple strip-shaped holes 302 are provided on both sides of the intercepting frame 3 for drainage. However, the strip-shaped holes 302 on both sides may also harbor debris. Foreign objects such as leaves affect drainage efficiency. After rainwater is collected in the water collection tank 2 at the bottom of the interception frame 3, the rising water level causes the float 405 to rise gradually due to buoyancy. Through the U-shaped rod 403 and the lifting plate 401, multiple triangular frames 402 gradually rise, allowing them to pass through the strip hole 302. Foreign objects at the strip hole 302 are pushed up. Because the top of the triangular frame 402 is more inclined, foreign objects on both sides of the interception frame 3 can more easily enter the collection frame 304. At the same time, when the water level inside the water collection tank 2 rises to its highest point, the tops of the three siphon pipes 202 are submerged underwater. At this time, under the action of siphon, the three siphon pipes 202 can quickly discharge water, causing the float 405 and multiple triangular frames 402 to descend, waiting for the next operation.

[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.
