[0002] Road drainage is a facility that combines road engineering to remove rainwater, snowwater, urban wastewater, groundwater and lower the groundwater level from the road surface and the ground. In order to prevent water accumulation on urban roads when it rains, rainwater drainage pipes are generally installed on both sides of the road, and then drainage outlets are opened on both sides of the road. Rainwater on the road surface will enter the drainage channel from the drainage outlets, and finally be discharged into rivers and lakes after being collected. There is generally a drainage cover in the drainage outlet to block larger debris in the water, such as leaves, stones and other larger garbage on the road, but there will still be some small debris that will clog the drainage pipe. When the rainfall is heavy, small debris will clog the drainage pipe and affect drainage. Workers need to open the drainage cover in the rain to clean up the debris clogged in the drainage pipe, which is time-consuming, labor-intensive and has safety risks. Utility Model Content

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0018] See also Figure 1 and Figure 2The utility model proposes an anti-clogging road drainage filtering structure, including a road body 1, a sewer 2 is opened inside the road body 1, a sewer cover 3 flush with the road surface is arranged on the sewer 2, a dirt blocking box 4 for intercepting impurities in sewage is arranged below the sewer cover 3, a partition 5 for intercepting impurities in sewage is fixedly arranged in the dirt blocking box 4, a baffle 6 is obliquely arranged in the dirt blocking box 4, one end of the baffle 6 abuts against the corner of the baffle 5, and the other end is connected to the upper end of the side wall of the dirt blocking box 4 through a first spring 7, the main body of the baffle 6 is hinged to the side wall of the dirt blocking box 4, a scraper strip 8 is horizontally arranged on the partition 5, and the scraper strip 8 is connected to the baffle 6 through an elastic rod, the space formed below the baffle 6 and the dirt blocking box 4 is a dirt storage chamber 9, and a water outlet 10 connected to the sewer 2 is arranged on the lower surface of the dirt blocking box 4.
[0019] The water discharge cover plate 3 is placed on the top of the dirt-blocking box, and the top surface is flush with the road surface, which does not affect the walking of vehicles and people on the road, and is convenient for subsequent cleaning of debris in the dirt-blocking box 4.
[0020] See also Figure 3 The partition 5 is n-shaped, with an inclined top surface and the highest in the middle. The bottom end of the partition 5 is fixedly connected to the trash box 4. The partition 5 has four planes, each of which is provided with a hole, and the diameter of the hole is smaller than the diameter of the drainage hole of the drainage cover plate 3. The lower surface of the trash box 4 below the partition 5 is provided with a water outlet 10 connected to the sewer 2; the partition 5 is used for secondary filtration of sewage.
[0021] The two baffles 6 are symmetrically arranged on both sides of the partition 5, and one end of the baffle 6 close to the side wall of the dirt-blocking box 4 is higher than the end of the baffle 6 abutting the corner of the baffle 5. Rainwater with debris first passes through the drainage cover 3, and the drainage cover 3 intercepts some larger debris. Rainwater carrying smaller debris enters the dirt-blocking box 4, and the rainwater enters the sewer 2 through the partition 5. The debris is intercepted by the partition 5 and accumulated at the connection between the baffle 6 and the partition 5 along the inclined partition 5.
[0022] A rotating shaft 11 protruding from the baffle 6 is arranged on the baffle 6 at a preset distance from the first spring 7, a bracket 12 protruding from the side wall is fixedly arranged on the upper part of the side wall of the dirt blocking box 4, the bracket 12 is rotatably connected to the rotating shaft 11, the baffle 6 can rotate around the rotating shaft 11 as the rotation center, and the ratio of the distance from the first spring 7 to the rotating shaft 11 to the length of the baffle 6 is 1:(1-3).
[0023] When the baffle 6 is in an inclined state and one end abuts against the limit block 13, the first spring 7 is in a compressed state, exerting a downward force on the end of the baffle 6 close to the side wall of the dirt-blocking box 4, which is balanced with the weight of the baffle 6 itself acting on the center position of the baffle 6; as the debris accumulated at the connection between the baffle 6 and the partition 5 increases, the gravity of the debris acts on the end of the baffle 6 close to the partition 5, and the compression of the first spring 7 intensifies. When the debris reaches a preset value, the first spring 7 reaches the maximum compression limit. When more debris is added, the force of the first spring 7 is less than the gravity of the debris, and the end of the baffle 6 close to the partition 5 rotates downward around the rotating shaft 11, and the debris falls into the dirt storage chamber 9.
[0024] A stopper 13 is provided at the abutment point of the baffle 6 and the corner of the partition 5. The stopper 13 is a triangular column, one side of the stopper 13 is in contact with the partition 5, another side is perpendicular to the partition 5 and is used to abut the baffle 6, and the third side is smoothly connected to the upper surface of the partition 5. After the debris falls into the dirt storage chamber 9, the force acting on the end of the baffle 6 close to the partition 5 is reduced, and the first spring 7 acts on the baffle 6 to make the end of the baffle 6 close to the partition 5 move upward, and the stopper 13 is used to limit the baffle 6 so that the baffle 6 returns to its original tilted state.
[0025] See also Figure 4 The scraper bar 8 is horizontally arranged on the partition 5, and the scraper bar 8 is connected to the baffle 6 through a slide 14, and the slide 14 is perpendicular to the scraper bar 8 and arranged at one end of the scraper bar 8. When the end of the baffle 6 close to the partition 5 rotates downward around the rotating shaft 11, the scraper bar 8 is driven to move downward along the partition 5.
[0026] One end of the scraper bar 8 close to the slide cylinder 14 is fixedly connected to the slider 17, and the slider 17 is slidably sleeved in the slide cylinder 14. The upper surface of the slider 17 is fixedly connected to the second spring 15, and the lower surface is fixedly connected to the pull rope 16. The other end of the pull rope 16 is fixedly connected to the baffle 6. The slide cylinder 14 is fixedly arranged on the side of the partition 5. The scraper bar 8 is provided with scraping hairs facing the partition 5. As the baffle 6 moves, the pull rope 16 pulls the slider 17 when it moves with the baffle 6, and drives the scraper bar 8 to move. The scraping hairs of the scraper bar 8 contact the partition 5, scrape off the debris on the partition 5, prevent the debris from clogging the partition 5, and avoid affecting the drainage; after the debris falls into the dirt storage chamber 9, the second spring 15 pulls the slider 17 to restore it to its original position.
[0027] The dirt storage chamber 9 has a partition 5 as a side wall. The debris falling into the dirt storage chamber 9 carries a small amount of rainwater, and the rainwater flows into the water outlet 10 through the partition 5, thereby preventing the debris from being soaked in rainwater for a long time and generating odor.
[0028] When cleaning the dirt storage chamber 9, take down the water discharge cover plate 3, rotate the baffle plate 6, and the sundries in the dirt storage chamber 9 can be cleaned.
[0029] When heavy rain occurs, the drainage volume of the top surface of the partition 5 is much smaller than the rainfall. When rainwater gathers in the dirt-blocking box 4, the gravity and water pressure of the rainwater act on the baffle 6. The force applied to the end of the baffle 6 with a lower horizontal height is large. When this force is greater than the force of the maximum compression limit of the first spring 7, the end of the baffle 6 close to the partition 5 rotates downward around the rotating shaft 11, and the rainwater can enter the dirt storage chamber 9 and enter the water outlet 10 from the storage chamber through the partition 5 for drainage. Therefore, this structure also has the function of emergency drainage.
