Background Art

In recent years, as the climate has become increasingly severe, there are often typhoons or heavy rainstorms. With the continuous advancement of road hardening and the expansion of road surface area, the drainage systems of highways and urban roads have been subjected to rounds of tests. If the drainage is not timely, rainwater will gather on the road, and vehicles driving at high speeds will cause the accumulated water to splash, which will not only pollute the vehicle, affect the driving vision, and easily cause traffic accidents, but also splash onto pedestrians nearby, seriously affecting pedestrians' passage, greatly increasing the difficulty and danger of traveling on rainy days. The existing road drainage system has too much workload, which can easily lead to blockage of individual drainage outlets due to long-term lack of maintenance. In the case of heavy rainfall, the water in the sewer is easy to gush out of the ground, causing more serious water accumulation on the road and affecting traffic safety.

A road drainage device is disclosed in Chinese patent CN211973771U, comprising: a sewer body 1, a filter grid, a stirring part and an anti-backflow grid, the stirring part comprising a fixed bracket, a motor and a circuit connector group, the inner wall surface of the sewer body 1 is paved with concrete, the bottom of the sewer body 1 is connected to the underground drainage pipe, the filter grid is fixedly installed at the top opening of the sewer body 1 by anchor bolts, the fixed bracket and the anti-backflow grid are both installed on the inner wall of the sewer body 1 by anchor bolts, and the vertical distribution relationship is that the fixed bracket is above the anti-backflow grid, the bottom of the fixed bracket is installed with a motor, and the output end of the motor is fixedly connected with a stirring fan blade, the circuit connector group is embedded and installed on the inner wall of the sewer body 1, and the circuit connector group is divided into a first group of connectors and a second group of connectors.

However, only a single stirring fan blade and a filter grid are provided, and when there is large debris in the stagnant water, for example, the stagnant water is mixed with soil from the green belt, the drain outlet is easily blocked, resulting in poor drainage. The staff needs to open the lid to clean the inside, which is not convenient for cleaning the debris.

DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

Referring to Figure 1, a municipal road drainage device that can automatically desilt includes: a sewer body 1, a stirring screw 2, a gravel filter plate 3 and block activated carbon 4, wherein the sewer body 1 is provided with a water inlet 5, a water outlet 6 and a cleaning port 7 in sequence along the vertical direction, wherein the water inlet 5 is located at the highest position of the sewer body 1, the cleaning port 7 is located at the lowest position of the sewer body 1, and the water outlet 6 is located between the water inlet 5 and the cleaning port. The stirring screw 2 is arranged below the water outlet 6 and is transmission-connected to a driving motor 8 arranged on the outer wall of the sewer body 1 so that it has the ability to rotate. The gravel filter plate 3 is fixedly arranged on the inner side wall of the sewer body 1 in a rotating body structure and is located below the stirring screw 2. The block activated carbon 4 is fixedly arranged on the inner bottom surface of the sewer body 1 and is located below the gravel filter plate 3.

In the above scheme, when the accumulated water on the road enters the interior through the water inlet 5 at the top of the manhole body 1, it is crushed and mixed by the stirring screw 2, so that the mud and gravel in the sewage are exposed, and the mixed sewage falls from the middle downward on the water diversion cone 9, and is guided to the surroundings by the water diversion cone 9. Then the sewage flow surges upward from the surroundings and passes through the gravel filter plate arranged obliquely downward. The gravel is blocked at this time and is rolled under the gravel filter plate by the water flow. The sewage passes through the upper activated carbon filter plate in the process of surging upward and the oil is adsorbed. Finally, the filtered sewage is discharged from the water outlet 6 at the top.

On the other hand, by connecting high-pressure hot water to the water inlet 5 above the sewer body 1 and opening the cleaning port 7 at the bottom of the sewer body 1, the oil and dirt adsorbed on the activated carbon filter plate will be separated from the filter plate under the action of rotation and high-pressure hot water, and the impacting water flow will pass through the gravel filter plate and flush the gravel and the oil and dirt out from the cleaning port 7, thereby achieving a self-cleaning function.

Referring to FIG. 2 , in one embodiment, the block activated carbon 4 is covered with a water dividing cone 9 , and the water dividing cone 9 is provided with holes 10 for water to flow through.

The gravel filter plate 3 is conical, and its panel is provided with sand filter holes of uniform size. The conical top of the gravel filter plate 3 is provided with a flow hole 11, and the flow hole 11 is suspended above the water dividing cone 9.

In the above scheme, the water diversion cone 9 can be set to divide the downward impact water flow to all sides, so as to avoid the sewage flow directly impacting the block activated carbon 4, so that the reverse water flow directly passes over the gravel filter plate 3. At the same time, the water diversion cone covered on the periphery of the gravel filter plate 3 provides a relatively stable space for the grease adsorption process of the block activated carbon 4, and the funnel-shaped setting can prevent the upwelling water flow from bringing the sand particles to the top of the gravel filter plate 3, and the filtered sand particles are always limited to the gravel filter plate 3.

Referring to Figure 3, in one of the embodiments, the sewer body 1 is set in an hourglass shape, and an activated carbon filter 12 is fixedly arranged on the inner wall of the sewer body 1, and the activated carbon filter 12 is arranged between the stirring screw 2 and the cleaning port 7, and the stirring screw 2 is horizontally inserted in the middle of the sewer body 1 set in an hourglass shape.

In the above scheme, the oily substances in the sewage can be filtered through the setting of the activated carbon filter 12, and the funnel-shaped sewer body 1 can guide the sewage sliding down from the top of the sewer body 1. The stirring screw 2 arranged horizontally at the lower end opening of the sewer body 1 can more effectively reduce the sand particles in the sewage from accumulating on the inner wall of the sewer body 1, compared with the stirring screw 2 arranged vertically inside the sewer body 1.

In one of the embodiments, the sewer body 1 is provided with a support plate 13 at the bottom of the range covered by the water diversion cone 9, and the support plate 13 is detachably connected to the bottom plate of the sewer body 1. An automatic replacement mechanism 14 is connected under the bottom plate of the sewer body 1, and the automatic replacement mechanism 14 is connected to the support plate 13. The automatic replacement mechanism 14 is a lifting mechanism that can drive the support plate 13 to move axially. The specific structure of the above-mentioned lifting mechanism belongs to the prior art for technicians in this field and will not be elaborated here.

For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system.
