[0002] A road refers to a highway, an urban road, and a place where social vehicles are allowed to pass. In order to prevent waterlogging on the road during rain, manholes are often opened at the edge of the road and connected to drain pipes for drainage.

[0003] However, for the current road structure with a drainage function, the manhole cover of the manhole usually has a filter screen. When the filter screen filters rainwater, the filtered garbage will adhere to the filter screen, easily causing blockage of the filter screen and affecting the drainage of the road. In view of the above problems, a road structure with a drainage function is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a road structure with a drainage function to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A road structure with a drainage function includes a road surface, a drain pipe, and a manhole. The drain pipe is buried at the bottom of the road surface, the manhole is opened in the road surface and connected to the drain pipe, and a manhole cover mechanism is fixedly installed in the road surface at the top of the manhole.

[0007] The manhole cover mechanism includes a mounting frame and an annular collection box. The mounting frame is arranged at the top end of the manhole and fixed in the road surface. The annular collection box is arranged at the bottom of the mounting frame and fixed in the road surface. A plurality of through holes are opened in the inner wall and the bottom part of the annular collection box located in the manhole. A manhole cover is clamped at the top of the mounting frame. A guide rod is fixedly connected to the middle of the bottom of the manhole cover. A sliding sleeve is slidably connected to the guide rod. A limiting plate is fixedly connected to the bottom end of the guide rod. A spring is sleeved on the guide rod between the limiting plate and the sliding sleeve. An umbrella-shaped filter screen is fixedly installed on the outer wall of the sliding sleeve. The bottom edge of the umbrella-shaped filter screen is above the annular collection box, and a connection mechanism is arranged between the umbrella-shaped filter screen and the annular collection box.

[0008] As a further scheme of the utility model: A plurality of support rods are fixedly installed on the side wall of the limiting plate at equal intervals in the circumferential direction, and a top ring is fixedly installed on the tops of the support rods together.

[0009] As a further scheme of the utility model: The connection mechanism includes a first connection ring and a second connection ring. The first connection ring is fixedly installed at the bottom of the umbrella-shaped filter screen, the second connection ring is fixedly installed at the top of the annular collection box, and a corrugated pipe is fixedly connected between the first connection ring and the second connection ring.

[0010] As a further solution of the utility model: the bottom end of the manhole is lower than the bottom of the drain pipe.

[0011] As a further solution of the utility model: the bottom of the manhole cover is symmetrically and rotatably connected with a rotating rod, the bottom end of the rotating rod is fixedly connected with a clamping plate, a clamping groove adapted to the clamping plate is formed in the inner wall of the installation frame, and a handle is fixedly installed on the rotating rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, rainwater flows into the manhole through the manhole cover, and the rainwater is filtered by the umbrella-shaped filter screen. The umbrella-shaped filter screen is impacted by the water flowing down from the manhole cover. Under the combined action of the sliding sleeve, the guide rod, the spring and the limiting plate, the umbrella-shaped filter screen jumps up and down. The objects filtered out at the top of the umbrella-shaped filter screen slide into the annular collection box under the action of the force. Moreover, when the umbrella-shaped filter screen moves downward, the mesh surface of the umbrella-shaped filter screen is jacked up by the top ring, which is beneficial to bounce the garbage attached to the umbrella-shaped filter screen, accelerate the flow of the filtered matter into the annular collection box, reduce the accumulation of the filtered matter on the umbrella-shaped filter screen, and cooperate with the shape of the umbrella-shaped filter screen, greatly avoiding the risk of blockage of the manhole cover mechanism. The filtered rainwater is collected in the drain pipe and transported, avoiding the accumulation of garbage in the drain pipe and the blockage of the drain pipe.

[0014] 2. When in use, the staff passes their fingers through the strip-shaped holes of the manhole cover and rotates the rotating rod through the handle. The rotating rod drives the fixedly connected clamping plate to be clamped with the clamping groove on the side wall of the installation frame, reducing the risk of the manhole cover falling off and the risk of pedestrians and vehicles.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a road structure with a drainage function includes a road surface 1, a drainage pipe 2, and a manhole 3. The drainage pipe 2 is buried at the bottom of the road surface 1, the manhole 3 is opened in the road surface 1 and is connected to the drainage pipe 2, and a manhole cover mechanism 4 is fixedly installed in the road surface 1 at the top of the manhole 3;

[0022] The manhole cover mechanism 4 includes a mounting frame 5 and an annular collection box 12. The mounting frame 5 is arranged at the top end of the manhole 3 and is fixed in the road surface 1. The annular collection box 12 is arranged at the bottom of the mounting frame 5 and is fixed in the road surface 1. A plurality of through holes 13 are opened in the inner wall and the bottom of the annular collection box 12 at the part in the manhole 3. A manhole cover 6 is clamped at the inner top of the mounting frame 5. A guide rod 7 is fixedly connected to the middle of the bottom of the manhole cover 6. A sliding sleeve 9 is slidably connected to the guide rod 7. A limiting plate 10 is fixedly connected to the bottom end of the guide rod 7. A spring 11 is sleeved on the guide rod 7 between the limiting plate 10 and the sliding sleeve 9. An umbrella-shaped filter screen 8 is fixedly installed on the outer wall of the sliding sleeve 9. The bottom edge of the umbrella-shaped filter screen 8 is above the annular collection box 12, and a connection mechanism is arranged between the umbrella-shaped filter screen 8 and the annular collection box 12.

[0023] When in use, rainwater flows into the manhole 3 through the manhole cover 6. The rainwater is filtered by the umbrella-shaped filter screen 8. The umbrella-shaped filter screen 8 is impacted by the water flowing down from the manhole cover 6. Under the combined action of the sliding sleeve 9, the guide rod 7, the spring 11, and the limiting plate 10, the umbrella-shaped filter screen 8 bounces up and down. The objects filtered out at the top of the umbrella-shaped filter screen 8 are forced to slide into the annular collection box 12 under the action of force, reducing the accumulation of the filtered substances on the umbrella-shaped filter screen 8. And in cooperation with the shape of the umbrella-shaped filter screen 8, the risk of the manhole cover mechanism 4 being blocked is greatly avoided. The filtered rainwater is collected in the drainage pipe 2 and is transported, avoiding the accumulation of garbage in the drainage pipe 2 and preventing the drainage pipe 2 from being blocked.

[0024] A plurality of support rods 14 are fixedly installed on the side wall of the limiting plate 10 evenly in a circumferential manner. A top ring 15 is fixedly installed at the common top of the support rods 14. When the umbrella-shaped filter screen 8 that bounces up and down moves downward, the mesh surface of the umbrella-shaped filter screen 8 is lifted by the top ring 15, which is beneficial to bouncing up the garbage attached to the umbrella-shaped filter screen 8 and accelerating the flow of the filtered substances into the annular collection box 12.

[0025] The connecting mechanism includes a first connecting ring 16 and a second connecting ring 18. The first connecting ring 16 is fixedly installed at the bottom of the umbrella-shaped filter net 8, and the second connecting ring 18 is fixedly installed at the top of the annular collection box 12. A corrugated pipe 17 is fixedly connected between the first connecting ring 16 and the second connecting ring 18. Under the guiding action of the first connecting ring 16, the corrugated pipe 17 and the second connecting ring 18, the larger garbage filtered out by the umbrella-shaped filter net 8 can be prevented from falling from between the umbrella-shaped filter net 8 and the annular collection box 12 to the bottom of the sewer well 3.

[0026] The bottom end of the sewer well 3 is lower than the bottom of the drain pipe 2, which can prevent the water flowing from the sewer well 3 from impacting the drain pipe 2, and part of the small solid particles in the collected water will gather at the bottom of the drain pipe 2.

[0027] The bottom of the manhole cover 6 is symmetrically rotatably connected with a rotating rod 19. The bottom end of the rotating rod 19 is fixedly connected with a clamping plate 21. A clamping groove 22 adapted to the clamping plate 21 is formed in the inner wall of the installation frame 5. A handle 20 is fixedly installed on the rotating rod 19. The staff's finger passes through the strip-shaped hole of the manhole cover 6 and rotates the rotating rod 19 through the handle 20. The rotating rod 19 drives the fixedly connected clamping plate 21 to be clamped with the clamping groove 22 on the side wall of the installation frame 5, reducing the risk of the manhole cover 6 falling off.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
