Description

A water guide and sewage barrier device for urban flood control and drainage wells

technical field

The utility model relates to the field of flood control and drainage, in particular to a water guide and sewage barrier device for urban flood control and drainage wells.

Background technique

The existing urban flood drainage design standards and related specifications are relatively old. Under the new situation of accelerated urbanization in China and the increase in the frequency of disastrous weather such as super heavy rains, the requirements for the construction and management of drainage facilities and the guarantee of urban operation safety Incompatible; every year in the rainy season, a large number of cities experience flooding and poor drainage, which have a great impact on people's lives and transportation. Road drainage and rainwater wells have become bottlenecks for smooth flood discharge; the lower part of existing rainwater wells is connected to drainage pipes, and there are seepage pipes extending downward at the bottom, which can replenish rainwater underground and allow excess rainwater to pass through drainage pipes Drain away, slow down land subsidence and prevent the road from being flooded during heavy rains. Some rainwater wells are also equipped with baskets, which can intercept dirt to prevent clogging of drainage pipes, and are easy to clean.

However, in areas with a large amount of water, usually low-lying, the rainwater carries a large amount of urban garbage and floating pollutants. In the traditional drainage process, the garbage and pollutants accumulate and block the rainwater wellhead or the protective cover (basket) at the mouth of the well , resulting in poor drainage and difficulty in cleaning up garbage and pollutants; at the same time, a large amount of rainwater leaked down, causing water sealing, resulting in poor drainage; in addition, during the drainage process, the common manhole cover was opened, under the cover of sewage, causing hidden dangers to pedestrians.

For this reason, it is necessary to establish a kind of urban flood control and drainage well water guiding and sewage barrier device, which can quickly guide water flow, collect and collect pollutants, and at the same time require easy disassembly and use, so as to achieve the goal of effective sewage drainage of rainwater wells.

Contents of the invention

The purpose of the utility model is to provide an urban flood control and drainage well water guide and sewage column device, which can realize the purpose of rapid drainage of urban flood and automatic interception of pollutants.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: an urban flood control and drainage well water guide and sewage barrier device, which is characterized in that it includes a sewage barrier structure, a water guide structure, an air guide rod, and a fixed ring;

The sewage fence structure includes a sewage fence net, a slag collection tank, and an air guide rod; the sewage fence net is ring-shaped, has a stainless steel mesh structure, and has certain flexibility; Stainless steel mesh structure; the outer ring of the slag collection tank and the inner ring of the fence net are connected by hinges; the air guide rod is a hollow stainless steel tube, which passes through the center of the slag collection tank;

Among them, the water guide structure includes a spiral water guide tank and a bottom net. The spiral water guide tank is an impermeable stainless steel ring, and the bottom net is four stainless steel bars. One end is connected to the inner edge of the spiral water guide tank, and the other end is connected to the air guide rod;

Among them, the air guide rod is divided into an upper rod and a lower rod. The diameter of the upper rod is smaller than that of the lower rod, and the upper rod can penetrate into the lower rod; the connecting section between the upper rod and the lower rod has springs, grooves and snap beads. Pull it out, and the spring will snap the ball into the groove to realize the fixing of the upper rod and the lower rod; there is a plastic button on the top of the upper rod, after pressing, the spring will bounce, and the upper rod can be pressed into the lower rod to realize folding effect;

Wherein, the fixed ring is in the shape of a ring, and the trash net and the spiral water guide can be fixed on the fixed ring; there is a suction cup at the bottom of the fixed ring, which can adsorb the fixed ring on the ground.

Among them, the trash net is composed of a radial mesh belt and a circular mesh belt. The radial mesh belt has serrations along the radial direction and is made of flexible plastic material. The serrations are inclined to the center of the trash net to achieve the effect of hooking.

Among them, the radial direction of the trash net is from low to high, and the slope gradually increases, and the vertical section shows the concave shape of the radial mesh belt of the trash net.

Among them, the spiral water guide groove is made of stainless steel, and there are water guide grooves distributed in a spiral shape on the upper surface; due to the influence of the geostrophic deflection force, when the water flow is discharged, the water flow automatically tends to rotate clockwise in the southern hemisphere, and the water flow automatically tends to rotate clockwise in the northern hemisphere. It tends to rotate counterclockwise. When the spiral water guiding groove is used for water guiding in the southern hemisphere, the spiral water guiding grooves are distributed clockwise. When the spiral water guiding groove is used for water guiding in the northern hemisphere, the spiral water guiding grooves are distributed counterclockwise.

Among them, the air guide rod can be extended upwards, and a warning sign is attached to it, which is used to warn pedestrians to pay attention to safety.

A method for a water guide sewage barrier device for urban flood control and drainage wells, the installation and operation of which include the following methods:

Step 1: Installation and layout. Before the summer rains come, select an area with poor rainfall and drainage in the city, connect the fence structure and water guide structure through a fixing ring, insert the air guide rod into the center of the fence structure and water guide structure, and fix it; Press the button on the top of the air guide rod to shrink the air guide rod and fold the water guide and sewage barrier device; place the manhole cover on the upper part of the rainwater well;

Step 2: Use. When the rain comes and the water accumulation area expands and the drainage is not smooth, in order to ensure rapid drainage and avoid debris in the sewage from blocking the drainage, open the well cover, pull out the air guide rod, and start the whole device. Carry out drainage fence.

Step 3: Operation, the local area of water increases, and under the action of gravity, the stagnant water entrains leaves, garbage, hair, dust and other sundries and gathers on the well cover. Under the action, it moves upwards along the trash-block net and falls into the slag collection pool, or is intercepted on the trash-block net;

The filtered rainwater forms a vortex flow state along the spiral water guide groove, so that there is space in the middle for ventilation, so that the rainwater can quickly flow into the drainpipe;

If the accumulated water increases further, the upper rod of the air guide rod can be stretched to be higher than the ground water level, and internal and external communication can be realized through the air guide rod.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model includes sawtooth, which can utilize the impact force of accumulated water waves to realize the interception, lifting, transportation and collection of garbage and pollutants along the sawtooth direction, and the pollutants are gathered above the drain, which is convenient for sanitation personnel to collect pollutants clean up.

According to the hydraulic direction, a water guide channel is established to smooth the flow state of the water flow, guide the water flow to rotate and discharge, and avoid the poor drainage caused by the water seal and the turbulence of the water flow.

It can be automatically folded, contracted and unfolded, easy to install and disassemble, and can be used without any modification to the existing project.

Under the condition of high water level, the air guide rod plays a role of ventilation and avoids water seal.
