Description

Technical Field

[0001] This utility model relates to the field of rainwater inlet technology, specifically a rainwater inlet with a sewage interception basket. Background Technology

[0002] Storm inlets are the final infrastructure in urban drainage systems that directly collect surface rainwater. They are key "interfaces" connecting surface runoff from roads and green spaces with underground stormwater pipe networks. Their core function is to quickly collect surface water formed by rainfall and transport it through pipe networks to sewage treatment plants or natural water bodies (such as rivers and lakes), ultimately achieving the goals of flood control and ensuring road traffic safety.

[0003] Currently, most existing storm drains with sewage interception functions use fixed filter structures with fixed filter pore sizes or flow channel dimensions. These cannot be dynamically adjusted based on actual blockage conditions. When the filter becomes clogged due to the accumulation of leaves, sand, and other impurities, the storm water flow channel narrows significantly, leading to a substantial decrease in water intake and hindering the rapid drainage of surface rainwater. Especially during moderate to heavy rain or downpours, the rate of rainwater accumulation within the storm drain far exceeds the rate of drainage, easily causing road flooding. This not only affects vehicle safety (e.g., tire slippage, engine water ingress) but may also pose a threat to pedestrian safety (e.g., slipping and falling while wading). Furthermore, these systems struggle to simultaneously meet both sewage interception and drainage needs under varying rainfall intensities. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the drainage efficiency of rainwater inlets with interception function is easily reduced due to filter clogging in the prior art, and to propose a rainwater inlet with interception basket.

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

[0006] A rainwater inlet with a sewage interception basket includes a rainwater inlet and a guide pipe. The guide pipe is symmetrically and fixedly connected to the bottom end of the rainwater inlet. An adjustment component and a cleaning component are provided inside the rainwater inlet.

[0007] The adjustment component includes a grid groove plate fixedly connected to the inner wall of the rainwater inlet. The bottom end of the grid groove plate is provided with a groove, and the inner wall of the grid groove plate is symmetrically provided with sliding grooves.

[0008] The cleaning assembly includes a drive rod rotatably disposed on the inner side of the grid groove plate, a connecting rod fixedly connected to the bottom end of the drive rod, and hinge blocks hinged to both ends of the connecting rod.

[0009] Preferably, the adjusting assembly further includes a limiting rod fixedly connected to the inner wall of the slide groove, a buffer spring sleeved on the outer wall of the limiting rod, a slider slidably connected to the outer wall of the limiting rod, a scraper fixedly connected to the end of the slider away from the limiting rod, and a grid groove plate fixedly connected to the inner wall of the scraper plate.

[0010] Preferably, the two ends of the buffer spring are fixedly connected to the first slide groove and the slider, respectively, and the size of the first scraper is adapted to the inner cavity size of the first grid groove plate.

[0011] Preferably, the dimensions of the second grid groove plate are adapted to the dimensions of the groove, and the dimensions of the first sliding groove are adapted to the dimensions of the slider.

[0012] Preferably, the cleaning assembly further includes a scraper two symmetrically sleeved on the bottom end of the grid groove plate two, the scraper two having a limiting groove on the side near the drive rod, and a scraper three fixedly connected to the bottom end of the grid groove plate one.

[0013] Preferably, the hinge block is limited to slide inside the limiting groove, and the size of the scraper three is adapted to the size of the grid groove plate two.

[0014] Compared with the prior art, this utility model provides a rainwater inlet with a sewage interception basket, which has the following beneficial effects:

[0015] 1. The rainwater inlet with intercepting basket filters debris through the first and second mesh troughs. If the filter becomes clogged due to accumulated debris, rainwater gradually accumulates in the inlet. Its gravity will squeeze the second mesh trough, causing the scraper and slider to slide downwards along the limit rod, while simultaneously compressing the buffer spring. During this process, the second mesh trough moves downwards relative to the groove, expanding the rainwater flow channel and significantly increasing the water intake, thus preventing road flooding. After the rainfall ends and the rainwater drains out, the buffer spring returns to its original position due to its elasticity, restoring the second mesh trough and the scraper to their normal filtration state. This system balances the interception effect with the drainage needs under different rainfall scenarios.

[0016] 2. When the rainwater inlet with the intercepting basket is reset by the buffer spring, scraper one slides upward with the mesh trough plate two, which can automatically scrape off the debris attached to the inner wall of the mesh trough plate one. At the same time, scraper three cleans the inner wall of the mesh trough plate two simultaneously, realizing the initial self-cleaning of the filter screen. On the other hand, if there are still residual impurities, the maintenance personnel only need to manually rotate the drive rod, which will drive the hinge block to slide in the limit groove through the connecting rod, pushing scraper two to make a horizontal reciprocating motion at the bottom of the mesh trough plate two, effectively removing the debris accumulated at the bottom of the filter screen. There is no need to disassemble the basket, simplifying the cleaning process and improving the maintenance efficiency. Attached Figure Description

[0031] Furthermore, the adjustment assembly 200 also includes a limiting rod 204 fixedly connected to the inner wall of the slide groove 203. A buffer spring 205 is sleeved on the outer wall of the limiting rod 204, and a slider 206 is slidably connected to the outer wall of the limiting rod 204. The size of the slide groove 203 is adapted to the size of the slider 206. The two ends of the buffer spring 205 are fixedly connected to the slide groove 203 and the slider 206 respectively.

[0032] Furthermore, the cleaning component 300 also includes a scraper 304 symmetrically fitted onto the bottom end of the grid trough plate 208. A limiting groove 305 is provided on the side of the scraper 304 near the drive rod 301. The hinge block 303 is limited and slids inside the limiting groove 305. A scraper 306 is fixedly connected to the bottom end of the grid trough plate 201. The size of the scraper 306 is adapted to the size of the grid trough plate 208.

[0033] When using this utility model

[0034] When rainwater flows through the top of the rainwater inlet 101 into the interior of the first grid plate 201 and the second grid plate 208, the rainwater is filtered by the grid plates 201 and 208 to remove impurities. When impurities clog the grid plates 201 and 208, the outflow of water is affected, causing the speed of rainwater flowing inside the grid plates 201 and 208 to be less than the inflow speed inside the rainwater inlet 101. As the rainwater gradually increases... At this time, the rainwater squeezes the second grid trough plate 208, causing the second grid trough plate 208 to move downward inside the groove 202 under the increasing gravity of the rainwater. This causes the second grid trough plate 208 to drive the first scraper 207 to move downward synchronously. The first scraper 207 then drives the slider 206 to move downward synchronously inside the first slide groove 203. This causes the slider 206 to slide downward on the outer wall of the limiting rod 204, which in turn causes the slider 206 to compress the buffer spring 205 and contract. As the second grid trough plate 208 slides downward inside the groove 202, the water intake of the device can be gradually increased.

[0035] Rainwater is filtered through the first grid trough plate 201 and the second grid trough plate 208 to remove debris. If the filter becomes clogged due to the accumulation of impurities, rainwater gradually accumulates in the rainwater inlet 101. Its gravity will squeeze the second grid trough plate 208, causing the scraper 207 and the slider 206 to slide downwards along the limiting rod 204, while simultaneously compressing the buffer spring 205. During this process, the second grid trough plate 208 moves downwards relative to the groove 202, expanding the rainwater flow channel and significantly increasing the water intake to prevent road surface water accumulation. After the rainfall ends and the rainwater drains away, the buffer spring 205 returns to its original position due to its elasticity, causing the second grid trough plate 208 and the scraper 207 to return to their original positions and restore normal filtration. This approach balances the effectiveness of intercepting dirt with the drainage needs under different rainfall scenarios.

[0036] After the rainwater drains from inside the first grid trough plate 201 and the second grid trough plate 208, the buffer spring 205, under its own compressed elasticity, drives the slider 206 to slide upward on the outer wall of the limiting rod 204. This causes the slider 206 to drive the scraper 207 and the second grid trough plate 208 to slide upward inside the first grid trough plate 201. As the scraper 207 moves upward, it cleans the debris on the inner wall of the first grid trough plate 201. Meanwhile, as the second grid trough plate 208 slides inside the first grid trough plate 201... In the process, scraper 306 cleans the inner wall of grid groove plate 208. Then, the operator manually rotates drive rod 301, which drives connecting rod 302 to rotate synchronously. Connecting rod 302 drives hinge block 303 to rotate synchronously. As hinge block 303 slides inside limit groove 305, it abuts scraper 304 and makes lateral reciprocating motion at the bottom of grid groove plate 208, so that scraper 304 cleans the debris at the bottom of grid groove plate 208.

[0037] When the buffer spring 205 resets, scraper 1 207 slides upward with mesh trough 208, automatically scraping away debris attached to the inner wall of mesh trough 201. At the same time, scraper 306 cleans the inner wall of mesh trough 208, achieving initial self-cleaning of the filter screen. On the other hand, if there are still residual impurities, maintenance personnel only need to manually rotate the drive rod 301, which will drive the hinge block 303 to slide in the limiting groove 305 through the connecting rod 302, pushing scraper 2 304 to make lateral reciprocating motion at the bottom of mesh trough 208, efficiently removing debris accumulated at the bottom of the filter screen. This eliminates the need to disassemble the hanging basket, simplifying the cleaning process and improving maintenance efficiency.

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.
