The urban drainage system planning is a component of the city's overall planning. The urban drainage system is usually composed of drainage pipes and sewage treatment plants. In the case of sewage and rainwater diversion, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled; rainwater runoff is collected by drainage pipes and discharged into nearby water bodies.

[0003] In the rainwater drainage system, parallel drainage ditches are generally set on both sides of the urban road, and a number of vertical shafts are set on the drainage ditches to be connected with the drainage ditches. Vertical shaft covers are set at the same level as the roads. When it rains, rainwater on the road flows into the drainage ditch through the drainage holes of the vertical shaft covers to achieve diversion and discharge of rainwater. During use, when rainwater flows to the vertical shaft covers, it is easy to carry dirt on the road surface, such as leaves, etc. These dirts are easy to block the drainage holes of the vertical shaft covers, causing the vertical shaft covers to lose the diversion effect, thereby causing local waterlogging on the road, affecting the safe use of the road.

DETAILED DESCRIPTION

[0028] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0029] See also Figure 1-10The utility model discloses a drainage diversion and anti-blocking structure for urban road pavement, comprising a drainage channel 1, which is a drainage ditch arranged on both sides of the urban road and parallel to the road, realizing the main flood discharge function, and a manhole cover 2 fixed on the top of the inner wall of the drainage channel 1, and a plurality of manhole covers 2 are arranged at a position flush with the urban road. The manhole covers 2 are provided with drainage holes arranged at equal distances. On rainy days, rainwater on the urban road is diverted to the drainage channel 1 through a plurality of manhole covers 2, and then discharged to the nearby water body through the drainage channel 1. A dredging mechanism is arranged below the manhole cover 2;

[0030] The unblocking mechanism includes top columns 14 arranged at equal distances and corresponding to the drainage holes. The top columns 14 correspond to the drainage holes of the manhole cover 2 one by one. Each top column 14 is connected by a connecting rod 15. The connecting rod 15 connects the top columns 14 as a whole. The top columns 14 move up and down reciprocatingly, and continuously push into and draw out from the drainage holes. When in use, on rainy days, a large amount of rainwater flows into the drainage channel 1 through the drainage holes of the manhole cover 2 arranged on both sides of the road. When the rainwater is diverted through the manhole cover 2, the rainwater will carry garbage and dirt on the road, such as leaves, and rush to the manhole cover 2. When the rainwater enters the drainage holes of the manhole cover 2, the dirt will often block the drainage of the manhole cover 2. Flow hole, for this purpose, the present application is specially designed with a dredging mechanism under the manhole cover 2, and the dredging mechanism is composed of top columns 14 corresponding to the drainage holes of the manhole cover 2 one by one. When rainwater flows through the manhole cover 2 and enters the drain 1, water potential energy will be generated, and the water potential energy will be used to drive the top column 14 to move up and down reciprocatingly, so that the top column 14 moves upward and pushes into the inside of the drainage hole of the manhole cover 2, so that the dirt inside the drainage hole of the manhole cover 2 is pushed out and washed away by the rainwater. The top column 14 constantly moves up and down to continuously dredge the drainage hole of the manhole cover 2, thereby preventing the drainage hole of the manhole cover 2 from being blocked during use, causing the situation of local flood discharge in urban roads.

[0031] In order to realize the effective work of the potential energy of rainwater, in the first embodiment, a drainage box 3 is provided on the bottom surface of the manhole cover 2, and the bottom wall of the drainage box 3 is arranged to be inclined from right to left. A rectangular through hole 11 is opened on the left side of the inner bottom wall of the drainage box 3. By providing the drainage box 3, the rainwater passing through the manhole cover 2 is first collected into the interior of the drainage box 3, and the gathering design of the bottom wall of the drainage box 3 makes the rainwater more concentrated, and the inclined design of the bottom wall of the drainage box 3 makes the rainwater gathered together after being collected and flow from right to left. When the rainwater flows to the left side of the interior of the drainage box 3, it flows downward from the rectangular through hole 11. Since the flow channel of the rectangular through hole 11 is reduced, the flow rate of the rainwater is accelerated, thereby achieving the purpose of effectively utilizing the gravitational potential energy of the rainwater.

[0032] In order to enable rainwater to drive the rotation of the impeller 9 and realize the conversion of the gravitational potential energy of rainwater into mechanical energy, in the first embodiment, a frame 4 is arranged on the left side of the bottom surface of the drainage box 3, and a rectangular flow channel is opened on the top surface of the frame 4 at a position corresponding to the rectangular through hole 11. The rectangular flow channel of the frame 4 is communicated with the rectangular through hole 11, and rainwater flows from the rectangular through hole 11 of the drainage box 3 into the rectangular flow channel of the frame 4. An impeller 9 fixed on the transmission shaft 10 is arranged inside the frame 4, and the impeller 9 is located below the rectangular flow channel of the frame 4. The outer surface of the transmission shaft 10 is rotatably connected to the frame 4. The accelerated rainwater flowing out of the rectangular flow channel of the frame 4 flushes the impeller 9 inside the lower frame 4, so that the impeller 9 rotates, and the rotation of the impeller 9 drives the transmission shaft 10 to rotate.

[0033] In order to further realize the rotation of the transmission shaft 10 to drive the top column 14 to achieve up and down reciprocating movement, in the embodiment, turntables 5 are fixed at both ends of the transmission shaft 10, and each turntable 5 is eccentrically connected to a connecting rod 6, and the top of each connecting rod 6 is rotatably connected to a guide rod 7, and the top of each guide rod 7 is fixedly connected to a slider 8. The rotation of the transmission shaft 10 drives the turntable 5 to rotate, and the rotation of the turntable 5 drives the connecting rod 6 to move. The movement of the connecting rod 6 drives the guide rod 7 to reciprocate up and down, and the up and down reciprocating movement of the guide rod 7 drives the slider 8 to reciprocate up and down.

[0034] Further.

[0035] The side of each slider 8 that is close to each other is fixedly connected to a sliding rod 12, and the side of each slider 12 that is close to each other is fixed to the corresponding top column 14, and the side of each slider 12 that is away from each other is slidably connected to a guide rail 13, and the left and right inner walls of the drainage box 3 are fixed to the corresponding two guide rails 13, and the outer surface of each slider 8 is slidably connected to the drainage box 3. When the slider 8 slides up and down inside the drainage box 3, it drives the sliding rod 12 to slide back and forth up and down on the inner wall of the drainage box 3, and the sliding rod 12 drives the top column 14 to move up and down, thereby realizing the up and down reciprocating movement of the top column 14. The top column 14 moves up and down, continuously pushing into the drainage hole of the manhole cover 2, clearing the drainage hole of the manhole cover 2, preventing the drainage hole of the manhole cover 2 from being dirty and blocked, and avoiding local water accumulation on urban roads.

[0036] When the amount of rainwater is too large, the rainwater is completely drained to work on the impeller 9 to realize the rotation of the impeller 9, which will cause the rainwater to flow down from the manhole cover 2 to the drain 1 in a delayed manner, resulting in a slow rainwater discharge speed, and thus losing the diversion function of the manhole cover 2. This embodiment 2 makes further improvements to this type of problem.

[0037] The inner side wall of the drainage box 3 is fixedly connected with a first drainage plate 16 and a second drainage plate 17 which are in the same inclination direction as the bottom plate of the drainage box 3. The inclination directions of the first drainage plate 16 and the second drainage plate 17 are both in the same inclination direction as the bottom wall of the drainage box 3. The left side of the first drainage plate 16 is higher than the right side of the second drainage plate 17. When rainwater enters the drainage box 3, it first falls on the first drainage plate 16, then flows downward to the second drainage plate 17, and then flows downward into the rectangular through hole 11 of the drainage box 3, so as to collect the kinetic energy of rainwater. When the amount of rainwater is large, When the water level of rainwater rises to the highest point of the second drainage plate 17, that is, the right end of the second drainage plate 17, the rainwater will overflow from the highest point of the second drainage plate 17, and flow into the right side of the drainage box 3 from the space between the first drainage plate 16 and the second drainage plate 17. At the same time, a main channel hole 18 is opened on the right side of the bottom wall of the drainage box 3. The rainwater entering the right side of the drainage box 3 will directly flow into the interior of the drain 1 from the main channel hole 18 opened on the bottom wall of the drainage box 3, so as to prevent the occurrence of problems such as excessive rainwater and untimely rainwater discharge.

[0038] When using the utility model: on rainy days, rainwater from urban roads flows into the interior of the drain 1 through the drainage holes of the manhole cover 2 to complete diversion and discharge. When rainwater flows through the manhole cover 2, the present application is specially designed with a drainage box 3, so that the rainwater first flows into the drainage box 3. The rainwater entering the drainage box 3 can push the unblocking mechanism to rotate, so that the top column 14 of the unblocking mechanism can move up and down, and then the top column 14 continuously pushes into the drainage hole of the manhole cover 2, so that the dirt inside the drainage hole of the manhole cover 2 is pushed out, and the drainage hole of the manhole cover 2 is unblocked.

[0039] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
