[0002] In urban drainage systems, storm drain grates are an important component, used to filter solid impurities in rainwater and prevent blockages in drainage pipes. However, traditional storm drain grates are prone to clogging by leaves, garbage, and other debris during long-term use, leading to reduced drainage efficiency and even causing localized waterlogging problems.
[0003] Existing technologies mainly rely on manual cleaning, which suffers from low efficiency, high cost, and inability to clean in real time. Mechanical cleaning devices are expensive and require regular maintenance. The use of chemical cleaning agents poses a risk of environmental pollution. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a vortex-type rainwater grate self-cleaning structure, which overcomes the deficiencies of existing technologies. It aims to solve the problems of existing technologies, which mainly rely on manual cleaning, resulting in low efficiency, high cost, and inability to clean in real time; mechanical cleaning devices are costly and require regular maintenance; and the use of chemical cleaning agents poses the risk of environmental pollution.
[0005] To achieve the above objectives, this application provides the following technical solution: a vortex-type rainwater grate self-cleaning structure, comprising a grate body, a filter frame disposed inside the grate body, a filter screen disposed inside the filter frame, a connecting ring disposed in the center of the filter screen, a connecting pipe disposed at the top of the grate body, the grate body and the connecting pipe communicating with each other, a top cover disposed at the top of the connecting pipe, a filter plate disposed inside the top cover, a driving mechanism disposed at the top of the filter frame, the driving mechanism being located at the top inside the grate body, the driving mechanism comprising multiple sets of vortex blades, a rotating shaft disposed at the bottom of the multiple sets of vortex blades, the bottom of the rotating shaft being rotatably connected to the inside of the connecting ring, a cleaning mechanism disposed between the driving mechanism and the filter frame, the cleaning mechanism comprising a rotating ring, the rotating ring being fixedly connected to the outside of the rotating shaft, multiple sets of cleaning rollers disposed outside the rotating shaft, each set of cleaning rollers having a cleaning brush disposed at its bottom, and the cleaning mechanism being located directly above the filter frame.
[0006] By adopting the above technical solution and setting a drive mechanism, during use, water resources enter directly from the top of the cover along the filter plate into the interior of the connecting pipe. Flowing continuously downwards through the connecting pipe, the water encounters the drive mechanism, which drives the vortex blades to rotate. This, in turn, drives the rotating shaft at the bottom to rotate, causing the cleaning mechanism to rotate. This allows the cleaning brush to continuously and quickly clean the filter screen, reducing clogging by debris. This setup achieves automatic cleaning of the rainwater grate without manual intervention. Furthermore, the greater the external rainfall, the better the cleaning effect, improving the overall efficiency of the rainwater drainage system, reducing localized water accumulation, effectively lowering maintenance costs, and featuring a simple structure that is easy to install and maintain, making it suitable for large-scale application.

This allows for quick collection of debris, making subsequent cleaning more convenient and further enhancing the practicality of the device.
[0009] As a preferred technical solution of this application, the connecting pipe is provided with multiple sets of vortex plates inside, the distance between the multiple sets of vortex plates is the same, and they are arranged in a threaded shape.
[0010] By adopting the above technical solution and setting up a vortex plate, the swirling phenomenon generated by the water flow after passing through the inside of the connecting pipe can be made stronger during use, which improves the driving effect of the bottom drive mechanism and further enhances the speed of water flow descent and cleaning effect.
[0011] As a preferred technical solution of this application, the bottom of the top cover is provided with an outward protrusion, and the top of the connecting pipe is provided with a fixing groove. The fixing groove and the outward protrusion are matched with each other, and the outward protrusion is engaged in the interior of the fixing groove.
[0012] By adopting the above technical solution and setting the protruding part, the connection between the top cover and the connecting pipe can be made tighter during use, and it is easier to separate the top cover from the connecting pipe later, thus further improving the practicality of the device.
[0013] As a preferred technical solution of this application, the top of the top cover is provided with a mounting groove, and a handle is provided inside the mounting groove.
[0014] By adopting the above technical solution and setting the mounting slot, the handle can be fixed inside the mounting slot during use, which can quickly open the top cover without affecting the external environment and effectively improve the practicality of the device.
[0015] As a preferred technical solution of this application, a fixing block is provided inside the collection box, and the fixing block is fixedly connected to the inner wall of the collection box.
[0016] By adopting the above technical solution and setting a fixing block, the collection box can be quickly removed from the inside during use, improving the practicality of the device.
[0017] As a preferred technical solution of this application, the cleaning brush is made of polypropylene, and the multiple sets of swirl blades are made of aluminum alloy.
[0018] By adopting the above technical solution, and by setting the cleaning brush to be made of polypropylene and the swirl blades to be made of aluminum alloy, it has a good corrosion resistance effect, which can greatly improve the service life and the stability during use.
[0019] The beneficial effects of this application are:
[0020] 1. By setting up a drive mechanism, during use, water resources enter directly from the top of the cover along the filter plate into the interior of the connecting pipe. Flowing continuously downwards through the connecting pipe, the water encounters the drive mechanism, which in turn drives the rotating shaft at the bottom. This causes the cleaning mechanism to rotate, allowing the cleaning brush to continuously and quickly clean the filter screen, reducing clogging by debris. This design achieves automatic cleaning of the rainwater grate without manual intervention. The greater the external rainfall, the better the cleaning effect, improving the overall efficiency of the rainwater drainage system, reducing localized water accumulation, effectively lowering maintenance costs, and featuring a simple structure that is easy to install and maintain, making it suitable for large-scale application.

A filter frame 5 is installed inside the grate body 1, and a filter screen 501 is installed inside the filter frame 5. A connecting ring 502 is located in the center of the filter screen 501. A connecting pipe 2 is installed at the top of the grate body 1, and the grate body 1 and the connecting pipe 2 are interconnected. A top cover 3 is installed at the top of the connecting pipe 2, and a filter plate 301 is installed inside the top cover 3. A drive mechanism 4 is installed at the top of the filter frame 5, located inside the top of the grate body 1, and drives... Mechanism 4 includes multiple sets of swirling blades 401, with a rotating shaft 402 at the bottom of each set of swirling blades 401. The bottom of the rotating shaft 402 is rotatably connected to the inside of the connecting ring 502. A cleaning mechanism 6 is provided between the drive mechanism 4 and the filter frame 5. The cleaning mechanism 6 includes a rotating ring 601, which is fixedly connected to the outside of the rotating shaft 402. Multiple sets of cleaning rollers 602 are provided outside the rotating shaft 402, and each set of cleaning rollers 602 has a cleaning brush 603 at its bottom. The cleaning mechanism 6 is located directly above the filter frame 5. Multiple sets of vortex plates 201 are provided inside the connecting pipe 2. The distance between the multiple sets of vortex plates 201 is the same, and they are arranged in a threaded shape.
[0030] By setting up the drive mechanism 4, during use, water resources enter directly from the top of the top cover 3 along the filter plate 301 into the interior of the connecting pipe 2. Flowing continuously downwards along the connecting pipe 2, the water encounters the drive mechanism 4, which drives the vortex blades 401 to rotate. This, in turn, drives the rotating shaft 402 at the bottom to rotate, causing the cleaning mechanism 6 to rotate. This allows the cleaning brush 603 to continuously and quickly clean the filter screen 501, reducing clogging by debris. This setup achieves automatic cleaning of the rainwater grate without manual intervention. The greater the external rainfall, the better the cleaning effect, improving the overall efficiency of the rainwater drainage system, reducing localized water accumulation, effectively lowering maintenance costs, and offering a simple structure that is easy to install and maintain, making it suitable for large-scale application. By setting up the vortex plate 201, the vortex phenomenon generated after the water flows through the connecting pipe 2 is further intensified, improving the driving effect of the drive mechanism 4 at the bottom and further increasing the speed of water descent and the cleaning effect.
[0031] Reference Figure 3 The filter screen 501 has a placement groove 503 inside, and a collection box 7 is installed inside the placement groove 503. A limiting edge 701 is provided on the upper outer side of the collection box 7. The collection box 7 is located inside the placement groove 503, and the limiting edge 701 abuts against the bottom of the filter screen 501. The bottom of the top cover 3 has an outward protrusion 304, and the top of the connecting pipe 2 has a fixing groove 202. The fixing groove 202 and the outward protrusion 304 are matched with each other, and the outward protrusion 304 is snapped into the inside of the fixing groove 202. A fixing block 702 is provided inside the collection box 7, and the fixing block 702 is fixedly connected to the inner wall of the collection box 7. The placement slot 503 allows the cleaning brush 603 to collect debris inside the collection box 7 as it rotates continuously during use. This enables quick collection of debris, making subsequent cleaning more convenient and further enhancing the practicality of the device. The protrusion 304 ensures a tighter connection between the top cover 3 and the connecting pipe 2 during use, and makes it easier to separate the top cover 3 from the connecting pipe 2 later, further enhancing the practicality of the device. The fixing block 702 allows the collection box 7 to be quickly removed from inside the 203 during use, further enhancing the practicality of the device.
[0032] Reference Figure 4The top of the top cover 3 has a mounting groove 302, and a handle 303 is provided inside the mounting groove 302. By setting the mounting groove 302, the handle 303 can be fixed inside the mounting groove 302 during use, which can quickly open the top cover 3 without affecting the external environment, thus improving the practicality of the device. The cleaning brush 603 is made of polypropylene, and the multiple sets of swirl blades 401 are made of aluminum alloy. By setting the cleaning brush 603 to be made of polypropylene and the swirl blades 401 to be made of aluminum alloy, it has good corrosion resistance, which can greatly improve the service life and improve the stability during use.
[0033] Working principle: By setting up the drive mechanism 4, during use, water resources enter directly from the top of the top cover 3 along the filter plate 301 into the interior of the connecting pipe 2. Flowing downwards along the connecting pipe 2, the water encounters the drive mechanism 4, which drives the vortex blades 401 to rotate. This, in turn, drives the rotating shaft 402 at the bottom to rotate, causing the cleaning mechanism 6 to rotate. This allows the cleaning brush 603 to continuously and quickly clean the filter screen 501, reducing clogging by debris. This setup achieves automatic cleaning of the rain grate without manual intervention. The greater the external rainfall, the better the cleaning effect, improving the overall efficiency of the rainwater drainage system, reducing localized water accumulation, effectively lowering maintenance costs, and featuring a simple structure that is easy to install and maintain, making it suitable for large-scale application. By setting up the placement slot 503, during use, the cleaning brush 603 collects debris inside the collection box 7 as it rotates, quickly completing the collection of debris and making subsequent cleaning more convenient, further enhancing the practicality of the device.
[0034] By setting the vortex plate 201, the swirling phenomenon generated by the water flow after passing through the inside of the connecting pipe 2 can be made stronger during use, which improves the driving effect of the bottom drive mechanism 4 and further enhances the speed of water flow descent and cleaning effect. By setting the protrusion 304, the connection between the top cover 3 and the connecting pipe 2 can be made tighter during use, and it is easier to separate the top cover 3 from the connecting pipe 2 later, further improving the practicality of the device.
[0035] Meanwhile, by setting the mounting slot 302, the handle 303 can be fixed inside the mounting slot 302 during use, which can quickly open the top cover 3 without causing damage to the external environment, thus improving the practicality of the device.
[0036] In addition, by setting the fixing block 702, the collection box 7 can be quickly removed from inside 203 during use, improving the practicality of the device; by setting the cleaning brush 603 to be made of polypropylene and the swirl blade 401 to be made of aluminum alloy, it has good corrosion resistance, which can greatly improve the service life and improve the stability during use.
