Description

Novel double-layer trash rack suitable for drainage pipe network

Technical Field

The utility model relates to a water treatment field especially relates to a novel double-deck trash rack suitable for drainage pipe network.

Background

At present, most of drainage pipe network systems of cities in China are combined system systems, and a large number of rain and sewage pipelines are in misconnection in the combined system systems. Many sewage pipe networks communicate be the rainwater box culvert, can have a large amount of rubbish to rush into sewage pipe network when raining, cause silt up stifled of sewage pipe network very easily.

In view of the above circumstances, traditional solution is to add a grid well at the drainage pipe network, installs a hand-basket grid of taking the guide rail in the well, can effectively reduce the drainage pipe network condition of clogging. After traditional basket grids are added, only the operation of cleaning and fishing garbage is needed to be carried out on the grid wells in the pipe network operation and maintenance process. However, conventional basket grates are typically heavy, resulting in lifting difficulties; because the traditional basket grid is mainly a single-layer grid, when the water flow in a pipe network is fast and the grid is blocked by garbage, the basket grid is difficult to lift due to the thrust of the water flow; the grid well provided with the basket grid has high difficulty in the manual cleaning process; and many basket grizzly screens have increased the grid clearance in order to reduce the frequency of rubbish clearance, lead to still that a large amount of pipeline rubbish can enter the drainage pipe network through the basket grizzly screen in the middle of.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above problem that prior art exists, provide a novel double-deck trash rack that is applicable to drainage pipe network in order to solve traditional hand-basket grid weight big, promote difficulty, clearance difficulty scheduling problem.

For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:

a novel double-layer trash rack suitable for a drainage pipe network comprises a first grid layer and a second grid layer; the grid aperture of the first grid layer is larger than that of the second grid layer;

the first grid layer is of a mesh structure;

the longitudinal section of the second grating layer is L-shaped and comprises a vertical arc-shaped plate and toe plates arranged at the bottom of the vertical arc-shaped plate;

the left side surface and the right side surface of the first grating layer are respectively matched with the left side surface and the right side surface of the vertical face arc-shaped plate, and the bottom of the first grating layer is connected with the toe plates to form a cavity with an upward opening and the top on the same horizontal plane.

Furthermore, the left side and the right side of the facade arc-shaped plate are provided with first clamping grooves for fixing the first grating layer.

Furthermore, a second clamping groove for fixing the first grid layer is formed in the toe board.

Furthermore, a stainless steel chain is arranged in the middle of the top of the first grid layer.

Furthermore, two sides and the middle of the top of the second grid layer are provided with a stainless steel chain.

Preferably, the first grid layer and the second grid layer are made of stainless steel.

The utility model discloses more traditional technique has following beneficial effect:

(1) the traditional grating usually adopts a single-layer form, and the technical scheme adopts a double-layer form, so that the efficiency of intercepting the garbage is improved, the cleaning and fishing frequency of an inspection well is reduced, and the blocking condition of a pipeline is reduced;

(2) the traditional grating usually needs to be specially provided with a grating well, and certain difficulty exists in the installation of the existing well; according to the double-layer grating in the technical scheme, the second grating layer is used as a base, the second grating layer is arranged into an arc shape, so that the double-layer grating can be directly additionally installed in a current inspection well, and the double-layer grating also plays a role in intercepting garbage;

(3) the traditional grille is usually made of carbon steel and is easy to corrode in a drainage system, and the grille in the technical scheme is made of stainless steel, so that on one hand, the corrosion resistance of the grille is improved, and on the other hand, the overall weight of the grille is also reduced;

(4) the traditional grating is usually installed up and down by installing the guide rail, the grating in the invention adopts an arc shape and can be attached to the inner wall of the inspection well, the installation of the guide rail is reduced, and the convenience of the installation and the lifting of the grating is improved.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 and 2, a novel double-layer trash rack suitable for a drainage pipe network comprises a first grid layer 1 and a second grid layer; the aperture of the first grid layer 1 is larger than that of the second grid layer; the first grating layer 1 is of a mesh structure, the longitudinal section of the second grating layer is L-shaped, and the second grating layer comprises a vertical arc-shaped plate 21 and toe plates 22 arranged at the bottom of the vertical arc-shaped plate 21; the left side surface and the right side surface of the first grating layer 1 are respectively matched with the left side surface and the right side surface of the vertical arc-shaped plate 21, and the bottom of the first grating layer 1 is connected with the toe plates 22 to form a cavity with an upward opening and the top on the same horizontal plane.

In this embodiment, the first grid layer 1 and the second grid layer are made of stainless steel, and have the characteristics of light weight and corrosion resistance.

The first grating layer 1 on the upstream side is a thick grating which is a stainless steel mesh (the gap is 40mm multiplied by 40 mm). The height of the coarse grid is consistent with that of the second layer of fine grid. The middle of the top of the coarse grating is provided with 1 stainless steel chain for lifting the coarse grating.
