The stagnant water on the road surface seriously affects the safety and smoothness of road driving. Therefore, it is particularly important to improve the design, construction and management level and quality of urban road rainwater drainage systems to make them more reasonable and effective in drainage.

[0003] There are many deficiencies in the current road drainage devices. The drainage outlets on the manhole covers are often blocked due to the accumulation of leaves on both sides of the road.

[0018] See also Figure 1-4 The utility model provides a technical solution: a self-draining road drainage cover plate, including a manhole cover 2, the manhole cover 2 covers the road drainage well 1, the surface of the manhole cover 2 is provided with a drainage hole 3, and the surface of the manhole cover 2 is covered with a scraper 5, and a rotating shaft 8 is fixedly installed below the end of the scraper 5, and the rotating shaft 8 passes through the manhole cover 2 and the rotating shaft of the fan gear 92 through a bearing to be fixed;

[0019] A reciprocating driving assembly 9 is arranged at the bottom of the manhole cover 2. The reciprocating driving assembly 9 includes a sector gear 92, a rack 93, a driving seat 94 and a servo electric cylinder 97. The driving seat 94 is installed on one side of the sector gear 92. At the same time, the end of the driving seat 94 is fixed to the piston rod of the servo electric cylinder 97, and the servo electric cylinder 97 is powered by a power module installed inside the sealed control box 91.

[0020] Working principle: When in use, the telescopic rod of the servo electric cylinder 97 moves back and forth, and drives the sector gear 92 to rotate back and forth through the rack 93, so that the scraper 5 rotates with the scraper 5 as the center, and the leaves covering the surface of the drainage hole 3 are swept away to prevent the leaves from blocking the drainage hole 3, making the drainage hole 3 unable to drain.

[0021] As a preferred embodiment, the scraper 5 is arranged in a straight line, and the brush 4 is screwed and fixed on the bottom of the scraper 5. At the same time, the brush 4 covers the surface of the manhole cover 2. The scraper 5 is a reciprocating rotating structure with the rotating shaft 8 as the center.

[0022] like Figure 4 As shown: the brush 4 is screwed to the bottom of the scraper 5. When the scraper 5 makes a circular motion, the brush 4 at the bottom contacts the surface of the manhole cover 2 to scrape off the leaves covering the three groups of drainage holes 3.

[0023] As a preferred embodiment, the bottom of the scraper 5 is welded to the guide block 6, and a guide groove 7 is opened on the surface of the manhole cover 2. At the same time, the guide groove 7 is set in a "C" shape, the guide block 6 is adapted to the size of the guide groove 7, and the guide block 6 is slidably set inside the guide groove 7.

[0024] like Figure 1-4 As shown: when the scraper 5 makes an arc motion, the guide block 6 at the bottom thereof is slidably set inside the guide groove 7, which can limit and guide the scraper 5 during movement, thereby preventing the scraper 5 from tilting during movement and ensuring the stability of the scraper 5 during movement.

[0025] As a preferred embodiment, three groups of drainage holes 3 are evenly arranged on the surface of the manhole cover 2, and the three groups of drainage holes 3 are distributed in a "C" shape. Leaves covering the surfaces of the three groups of drainage holes 3 are scraped off by the moving scraper 5.

[0026] like Figure 4 As shown: the three groups of drainage holes 3 are distributed in a "C" shape. In the rainy season, the three groups of drainage holes 3 can be used to drain the accumulated water on the road surface. At the same time, the setting of the three groups of drainage holes 3 can increase the discharge of rainwater.

[0027] When the manhole cover 2 is actually installed, it needs to be installed in a position where no vehicles are traveling to prevent the scraper 5 from being crushed by vehicles.

[0028] As a preferred embodiment, a rack 93 is fixedly disposed on one side of the driving seat 94 , and a guide seat 95 is fixedly disposed on the other side of the driving seat 94 , and the rack 93 is adapted to the size of the sector gear 92 , and the rack 93 is meshedly connected with the sector gear 92 .

[0029] like Figure 1-4 As shown: the driving method of the scraper 5 is: the telescopic rod of the servo electric cylinder 97 drives the driving seat 94 to reciprocate, and the rack 93 drives the sector gear 92 to reciprocate, and driven by the rotating shaft 8, the scraper 5 is driven to reciprocate.

[0030] As a preferred embodiment, a guide hole is opened inside the guide seat 95, and a guide rod 96 is inserted into the guide hole opened on the guide seat 95. At the same time, the guide rod 96 is installed on the sealing control box 91, and the sealing control box 91 and the manhole cover 2 are sealed by a rubber pad.

[0031] The sealing control box 91 and the manhole cover 2 are sealed by a rubber pad to prevent water from entering the control box 91. A rain sensor can be installed on the manhole cover 2. This device can be purchased directly on the market. Through the rain sensor and the controller, the driving seat 94 is driven to work automatically when it rains to remove the leaves covering the drainage hole 3, thereby completing the self-dredging work of the drainage hole 3 on the manhole cover 2 without manual intervention.

[0032] The rain sensor, controller and servo electric cylinder 97 are commonly used devices in this field and can be purchased directly on the market. Their working principles and circuit connection methods of the controller are also well known to people in this field. They are not necessary technical features of this case and will not be described here.
