Abstract

The utility model relates to the technical field of water conservancy channel trash holding, and discloses a trash holding grid for a water conservancy channel, which comprises a grid plate and a lifting assembly arranged on the front surface of the grid plate, wherein the upper part of the grid plate is provided with a scraping assembly with a scraping plate, the back surface of the grid plate is provided with a lifting plate connected with the lifting end of the lifting assembly, and the surface of the lifting plate is uniformly provided with water draining holes to realize solid-liquid separation. The two sides of the lower part of the back of the grid plate are provided with a protective outer cylinder, the inner cavity of the protective outer cylinder is provided with a guide block and a reset spring through a guide post, and the upper surface and the lower surface of the protective outer cylinder are provided with two-way through grooves for the supporting rods connected with the guide block to pass through and slide. When the lifting plate descends, the pushing plate moves outwards along the guide post through the guide block and extrudes the reset spring, and accumulated sundries are pushed outwards. The device realizes the functions of dirt blocking, dirt cleaning and slag discharging through mechanical linkage, prevents sundries on the back of the grid from depositing, and the buffer mechanism absorbs movement impact.

Description

Trash rack for water conservancy channel Technical Field The utility model relates to the technical field of water conservancy channel trash, in particular to a trash rack for a water conservancy channel. Background The key purpose of setting up trash rack in the water conservancy channel is to intercept floater, suspended solid and impurity in the rivers to guarantee channel function normal operating, protection low reaches facility safety and maintain quality of water ecology, the filth is piled up in the channel and can be reduced the flow section, reduces water delivery ability, causes the flood bank risk even. The trash rack is convenient to clean regularly by intercepting the dirt intensively, maintains the design flow of the channel, and meanwhile, if the dirt (such as branches, plastic garbage and pasture and water) enters the water turbine, the dirt can wind the rotating wheel and block the water guide mechanism, so that mechanical abrasion, efficiency reduction and even shutdown accidents are caused. The trash rack can intercept the sundries in advance, so that the equipment failure rate is reduced. Traditional water conservancy is trash rack for canal, in falling into the water and utilizing the canal with the trash rack, rivers remove through the trash rack, and the trash rack then intercepts the filth in the rivers, under long-time use, leads to the filth to pile up in trash rack department to form the jam phenomenon, influence rivers normal clear. In order to solve the problem, the trash rack for part of water conservancy channels is provided with a lifting structure and a scraping mechanism, the lifting end of the lifting structure is provided with a lifting plate, when the lifting plate ascends along with the lifting structure, dirt intercepted by the trash rack can be driven to ascend, and the scraping mechanism scrapes out the dirt on the lifting plate outwards, so that the blocking phenomenon is avoided, and normal passing of water flow is guaranteed. However, in this way, the lifting plate can drive part of non-dirt to descend under water when being reset and descended, so that not only is the dirt cleaning effect reduced, but also the dirt cleaning difficulty is improved. Therefore, a trash rack for water conservancy channels is provided. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a trash rack for a water conservancy channel, which solves the technical problems that the trash cleaning effect is reduced and the trash cleaning difficulty is improved. (II) technical scheme In order to achieve the purpose, the utility model provides the following technical scheme that the trash rack for the water conservancy channel comprises: The lifting assembly is arranged on the front face of the grid plate, the scraping assembly is arranged on the upper surface of the grid plate, the scraping plate is additionally arranged at the moving end of the scraping assembly, and the lifting assembly is connected with the scraping assembly; The lifting plate is arranged on the back surface of the grid plate, drain holes are uniformly formed in the upper surface of the lifting plate, the lifting plate is connected with the lifting end of the lifting assembly, drain holes are uniformly formed in the upper surface of the lifting plate, and the lifting plate is connected with the lifting end of the lifting assembly; The protection urceolus sets up in the back lower part both sides of grid board, and the guide post is installed to the inner chamber of protection urceolus to the guide block and reset spring have been overlapped respectively in the surface of guide post, and outer logical groove has all been seted up to the upper surface and the lower surface of protection urceolus, and the laminating has the bracing piece in the upper surface slip of protection urceolus, and the bracing piece is connected with the guide block, and installs the scraping wings in the top of bracing piece, and the lower surface slip laminating of scraping wings and lifter plate. When rivers pass through the grid board, floater and solid debris are intercepted in the grid board openly, lift assembly starts this moment, drive the lifter plate and rise perpendicularly along the grid board back, the lifter plate rises the in-process, its surface evenly distributed's waterlogging caused by excessive rainfall hole is continuous to discharge the water that carries debris, realize solid-liquid separation, the lifter assembly drives the lifter plate and rises, the removal end through mechanical linkage drive scraping assembly operation of scraping the material subassembly drives the scraper plate and along grid board surface horizontal migration, scrape the positive debris of grid board of attaching to the channel both sides and collect the region, the lifter assembly drives the lifter plate and descends when reset, lifter plate lower surface and pushing away
