Description

A step overflow weir for urban river ecological management

Technical Field

The utility model relates to an overflow weir equipment field specifically is a step overflow weir for urban river ecological management.

Background

The overflow weir is a structure that liquid overflows on the tower plate, has the functions of maintaining a liquid layer on the plate and enabling the liquid to overflow uniformly, and can be divided into an outlet weir and an inlet weir. The overflow weir is mostly provided with an arched weir, and the length of the weir can be 0.6 to 0.8 times of the diameter of the tower. The outlet weir is generally a flat weir, and when the flow rate is small, a tooth-shaped weir can be adopted, and the height of the weir depends on different plate types and liquid load. The inlet weir is primarily intended to reduce the impact of liquid rushing out at the inlet on the flow of tray liquid.

In some watersheds needing water storage, the water discharge opening is provided with an overflow weir, but most of the overflow weirs cannot block garbage in water flow, so that the garbage in the water flow flows along with the water to cause water pollution, and meanwhile, when no overflow exists, aquatic microorganisms in a weir bed easily die due to water shortage, so that certain defects exist.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows: an object of the utility model is to provide a step overflow weir for urban river ecological management can block the rubbish in the rivers, prevents that aquatic rubbish from continuing to drift, causes the pollution to water, also enables the aquatic microorganism normal existence when not having the overflow in the weir bed simultaneously.

The technical scheme is as follows: the utility model provides a step overflow weir for urban river ecological management, includes riverbed and weir bed, riverbed top surface tiling has the brick slabstone, brick slabstone top surface is equipped with weir body bottom plate, be equipped with weir bed in the middle of the weir body bottom plate, weir bed is equipped with first weir body in high water level department, weir bed is equipped with the second weir body in low water level department, first weir body all is equipped with the rubble heap with second weir body department against the current, weir bed top surface is symmetrical evenly distributed fixed mounting and has two second swivels, two second swivel other end swing joint has the curb plate, two fixed mounting has the coarse mesh net in the middle of the curb plate.

As a further aspect of the present invention: the curb plate is close to second weir body one side fixed mounting has first swivel mount, first swivel mount other end fixed mounting has the spring telescopic link, spring telescopic link bottom fixed mounting is on the weir bed.

As a further aspect of the present invention: the first weir is higher than the second weir and is same in shape, the coarse mesh is higher than the second weir, and the coarse mesh is lower than the first weir.

Has the advantages that: overflow weir, when rivers flow, when overflowing first weir body, its unnecessary water flows into among the weir bed, among the rubbish that its rivers carried flows into the weir bed, block by the coarse mesh net in the weir bed, prevent that the rubbish of aquatic from continuing to drift, cause the pollution to water, when rivers torrent is urgent, can flow into among the weir bed fast, strike the coarse mesh net, during the impact, its spring telescopic rod of installing cushions, guarantee the stability of coarse mesh net at rivers impact, the rivers after the filtration are flowed by the second weir body, at this moment, the storage has water in its weir bed, guarantee that the aquatic microorganism in the weir bed also can normally survive when not having the overflow.

Detailed Description

The following examples further illustrate the invention but are not to be construed as limiting the invention. Modifications and substitutions of methods, steps or conditions of the present invention may be made without departing from the spirit and substance of the invention. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.

Example 1

As shown in fig. 1-2, a step overflow weir for ecological management of urban river channels comprises a riverbed 1 and a weir bed 7, wherein brick plates 5 are tiled on the top surface of the riverbed 1, a weir body base plate 4 is arranged on the top surface of the brick plates 5, the weir bed 7 is arranged in the middle of the weir body base plate 4, a first weir body 3 is arranged at a high water level of the weir bed 7, a second weir body 6 is arranged at a low water level of the weir bed 7, gravel piles 2 are arranged at the positions of the first weir body 3 and the second weir body 6 in a countercurrent manner, two second rotating frames are symmetrically, uniformly distributed and fixedly arranged on the top surface of the weir bed 7, the other ends of the two second rotating frames are movably connected with side plates 8, and a coarse mesh 12 is fixedly arranged in the middle of the two side plates 8;
