Description

Garbage filter device under rainwater grate

technical field

The utility model relates to the fields of municipal engineering and environmental engineering, in particular to a garbage filtering device under a rainwater grate.

Background technique

Rainwater grate is an important part of urban municipal road drainage system, which is directly related to the normal performance of urban drainage function. At present, the existing rainwater grate has a large diameter and can only filter larger stones, leaves, plastics and other garbage, while smaller garbage can easily enter the rainwater grate, which will accumulate in rainwater wells and pipes for a long time Cause blockage, affect the drainage capacity of rainwater pipes in rainwater wells, and a large amount of fixed particle pollutants and suspended pollutants enter rivers and lakes with stormwater outlets, and easily cause water and environmental pollution. In addition, because the rainwater wells are generally deep and the wells are narrow, the cleaning work is cumbersome, especially before the rainy season, the management department needs to invest a lot of manpower and material resources for dredging, which is labor-intensive and expensive. If it is not cleaned in time or not thoroughly, and the rainwater cannot be removed in time, it will cause a large amount of water on the ground, which will affect the normal operation of the road and traffic safety, and even cause traffic accidents and casualties, with serious consequences. Therefore, under the premise of ensuring the rainwater flow capacity of the rainwater well, it is necessary to install a matching filter device with the function of collecting rainwater discharge and "underground garbage bin" under the rainwater grate.

Contents of the invention

The purpose of the utility model is to provide a garbage filtering device under the rainwater grate, which solves the problems that the existing rainwater grate cannot effectively intercept garbage, the rainwater pipe is blocked, the environment is polluted, and the cost of dredging is high. The device is simple in manufacture, convenient in installation and use, low in cost and good in effect, and is suitable for new construction and renovation of existing rainwater wells.

The purpose of this utility model is achieved through the following technical solutions.

A garbage filtering device under rainwater grates, comprising a steel reinforcement frame, a bottom plate, a side plate, a steel wire mesh, a handle and a pull ring, the bottom plate is arranged on the bottom surface of the device, and side plates are arranged around a certain height from the bottom surface, and the bottom plate and the side plates are connected with the steel bars Skeleton welding connection, characterized in that: the shape of the upper mouth of the device is adapted to the shape of the rainwater grate. It is an inverted quadrangular platform structure with a large upper mouth and a small lower bottom. It is arranged directly under the rainwater grate, and the top of the rainwater pipe upper part.

The bottom surface of the device is closed, and side plates are set around a certain height from the bottom surface, so that the bottom of the device has a certain storage volume; each side of the device is equipped with steel mesh as a drain hole; the four corners of the upper mouth of the device are respectively set The pull ring is connected and fixed to the rainwater well through the wire rope hook on the grate seat. At the same time, a movable handle is set in the middle of the upper mouth, and the garbage is cleaned easily; a pull ring is set at any corner of the bottom of the device, and the anti-theft A wire rope is attached to the stormwater well to deter theft. After the rainwater enters the device, it enters the rainwater well through the drain hole, and the garbage in the water larger than the drain hole is intercepted in the device. At the same time, some heavy fixed garbage in the water settles to the bottom of the device, which can be cleaned regularly, which is very convenient. Under the premise of ensuring the rainwater flow capacity, the device can effectively filter garbage in water, reduce the cost of dredging underground rainwater wells, and effectively protect the environment, and has good economic and environmental ecological benefits.

The overall frame of the device is welded by short steel bars with a diameter of 6 or 8 mm, and the surface of the steel bars is coated with antirust paint.

Each side of the device is equipped with a steel wire mesh as a drain hole. The steel wire is high-quality carbon fine steel wire and coated with anti-rust paint. The diameter of the steel mesh is 5-10mm. The steel mesh and the steel frame are fixed by welding or binding. The design of the inverted square platform structure makes the steel wire mesh have a certain inclination angle, which improves the rainwater discharge capacity of the device.

The four corners of the upper mouth of the device are respectively provided with pull rings, which are welded to the steel frame, and the four pull rings are on the same horizontal plane, and are connected to the rainwater well through the wire rope hooks provided on the grate base, which is convenient for disassembly and assembly.

A movable handle is arranged in the middle of the upper mouth of the device, and the material of the handle is plastic or steel. When removing the garbage at the bottom, you only need to open the rainwater grate, and use the handle to lift out the garbage, which reduces the cost and labor intensity of garbage cleaning in the rainwater well. It has the function of "underground garbage bin", which is simple and convenient.

Set a pull ring at any corner of the bottom of the device, the pull ring is welded to the steel frame, and connected to the rainwater well through the anti-theft wire rope on the grate seat. The anti-theft wire rope needs to reserve a certain length, so that the device can be taken out to clean up the garbage, and at the same time prevent theft.

The utility model has the function of rainwater drainage and "underground garbage bin", and has low production cost, strong drainage capacity, convenient use, anti-theft, and can effectively intercept garbage at the same time, ensuring the smooth collection and discharge of rainwater, and has remarkable advantages. Environmental ecological benefits and economic and social benefits.
