Description

Technical Field

[0001] The present invention relates to the technical field of sponge city roads, and in particular to a sponge city ecological municipal road for a Lanni River basin. Background Art

[0002] Urban roads are the hub of human social progress and economic development. While bringing huge benefits to human society, they also bring many negative impacts on natural landscapes and ecosystems. As an important part of urban catchment areas, urban roads are also one of the main sources of non-point source pollution in urban receiving water bodies. The runoff pollution caused by rainwater runoff from urban roads has attracted increasing attention. Constructing a new type of sunken green space with the concept of "sponge city" is to improve the functions of urban green space such as rainwater purification, drainage, groundwater recharge, and storage. It changes the traditional concept of water resource management and can effectively reduce the impact and damage to the ecological environment.

[0003] The sunken green space is a green space that is lower than the surrounding ground. It uses open space to receive and store rainwater to reduce runoff. The sunken green space is widely used between urban roads. Municipal pipelines are set inside the green space to guide the introduced water to the water storage equipment. The municipal pipeline is equipped with an overflow pipe. When the liquid level exceeds the overflow pipe, the water automatically overflows the pipe and flows into the municipal pipeline.

[0004] The end of the overflow pipe is usually provided with a filter such as a geotextile to prevent dirt and other impurities from entering the pipe and purify the rainwater. However, dirt and other impurities are easily accumulated on the surface of the filter such as the geotextile, which can easily clog the filter and affect the water conduction efficiency of the overflow pipe.

[0005] A rainwater interception and purification system for low-lying green roads in sponge cities with a publication number of CN114855977B comprises: a water pipe and an overflow pipe, a grid plate is installed at the top of the overflow pipe, and a first filter element is arranged on the outside of the grid plate; an extension part, the extension part is installed at the upper end of the surface of the overflow pipe; a mounting frame, the mounting frame is installed on one side of the extension part; a driving mechanism, the driving mechanism is installed on the mounting frame; a driving arm, the driving arm is rotatably connected to the mounting frame. The rainwater interception and purification system for low-lying green roads in sponge cities provided by the present invention has a driving mechanism that cooperates with a driving arm, a cleaning arm and a rainwater sensor. When draining water through the overflow pipe, the driving mechanism drives the cleaning arm to rotate through the driving arm to clean the surface of the first filter element, avoid the accumulation of impurities such as mud on the surface of the first filter element, avoid clogging the first filter element, and ensure the water conduction efficiency.

[0006] In the above technical solution, it is not possible to quickly realize the recovery of precipitation and better supply water to the green belt during the corresponding dry season, so improvement is needed. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a sponge city ecological municipal road for the Lanni River Basin.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A pipe body is provided through one side of the lower end of the drainage square frame, and the pipe body is located at one end of the drainage square frame away from the pavement assembly;

[0011] Two winding wheels are installed from top to bottom at the bottom of the drainage frame, and a pull rope is wound around the two winding wheels. A float assembly is fixed at one end of the pull rope, and the float assembly is located at the lower end of the drainage frame;

[0012] A closing mechanism is rotatably connected to a side wall at one end of the drainage frame, the closing mechanism and the pipe body are arranged through one end of the drainage frame and correspond to each other, and the other end of the pull rope is connected to the closing mechanism;

[0013] A water delivery mechanism is arranged at one end of the pipe body away from the drainage frame.

[0014] Compared with the prior art, the present application can effectively allow rainwater to quickly enter the drainage ditch from the road surface, and when the rain is too heavy, the screen member and the mounting frame can be quickly reciprocated to ensure that the surface of the screen member can be cleaned while the rainwater enters the drainage frame member, and when the amount of rain is too large, the pipe body member can be effectively closed. When the amount of rain is small or there is no rain, the rainwater can be easily supplied to the green belt through the pipe body member, and the rainwater can be quickly returned to the drainage ditch and the drainage frame member for easy collection, thereby ensuring the driving effect of the road surface.

[0015] Preferably, the water delivery mechanism comprises a plurality of circular tubes which are arranged at equal intervals through one end of the tube body away from the drainage frame, the circular tubes are located at the lower end of the tube body, and a filter is installed in the circular tubes.

[0018] Furthermore, when there is excessive water accumulation on the road surface, it can enter the drainage channel through the drainage component and the bearing component, so as to fully ensure the driving effect of the road surface, and the cleaning connection mechanism can effectively ensure that rainwater enters the drainage frame to avoid the entry of impurities.

[0020] Furthermore, when there is too much rainwater in the drainage ditch, the rainwater will pass through the opening to activate the driving mechanism. The operation of the driving mechanism can cause the slide bar to continuously move back and forth, so that the mounting frame and the screen member can move in the opening, and the screen member can enter the drainage ditch. As the rainwater flows, the surface of the screen member can be effectively cleaned, making it easier for rainwater to pass through the screen member and enter the drainage frame member.

[0028] Furthermore, when the amount of rainwater is large, the pull rope can be used to drive the pressure plate and the sealing member to rotate, so that the sealing member and the side wall inside the drainage frame member can collide with each other, and the pipe body member can be effectively blocked to prevent rainwater from entering the pipe body member.

[0029] Preferably, the upper end of the drainage component, the upper end of the bearing component and the upper end of the pavement component are arranged flush.

[0030] Furthermore, it can facilitate the flow of rainwater. During actual production and preparation, the pavement component is tilted toward the direction of the bearing component, so that rainwater can enter the drainage channel through the drainage component and the bearing component.

[0036] 3. When there is too much rainwater in the drainage channel, the rainwater will pass through the opening to make the driving mechanism work. The operation of the driving mechanism can make the slide bar move back and forth continuously, so that the installation frame and the screen piece can move in the opening, and the screen piece can enter the drainage channel. With the flow of rainwater, the surface of the screen piece can be effectively cleaned, so that the rainwater can pass through the screen piece and enter the drainage frame piece. The screen piece, the installation frame and the horizontal connecting rod are all made of stainless steel, which can extend the service life of the components.
