Embodiment 1

[0018] see Figure 1-2 , a cleaning device for the bottom grill, which includes a plane support seat 5, on which a main shaft 8 is vertically supported by a bearing 6, and the top of the main shaft 8 is fixedly equipped with a cleaning scraper 3, and the cleaning scraper The plate 3 fits with the upper surface of the bottom grid 4, the bottom of the main shaft 8 is fixedly fitted with runner blades 7, the lower surface of the bottom grid 4 is equipped with a confluence plate 2, and the water outlet of the confluence plate 2 is arranged on the rotary Just above the wheel blade 7. Through the above structure, the gravitational potential energy of the water flow can be converted into the kinetic energy of the blades of the runner, and then driven to rotate, driving the cleaning scraper 3 to perform cleaning treatment.

[0019] Further, through the gravitational action of the water flow, its gravitational potential energy is converted into the kinetic energy of the main shaft 8, ...

Embodiment 2

[0024] Adopt the cleaning method of the bottom grid grid cleaning device of implementation 1, the confluence plate 2 arranged on the bottom surface of the bottom grid grid 4 will collect the water to the bottom of the conical funnel, and the water after the confluence will impact the runner blade 7 , and then convert the gravitational potential energy of the water into kinetic energy, the runner blade 7 rotates under the action of the water flow, and then drives the main shaft 8 to rotate, and the rotation of the main shaft 8 will further drive the cleaning scraper 3 on the top to rotate, and the cleaning scraper 3 will The sludge on the upper surface of the bottom grid 4 is scraped and cleaned, and the scraped sludge or sundries will continue to be washed down to the bottom of the bottom grid 4 by the water flow.

[0025] Work process and working principle of the present invention are:

[0026] During the working process, water can be collected to the bottom of the conical fu...

Abstract

The invention relates to a bottom grid barrier dirt removing device and method. The bottom grid barrier dirt removing device comprises a plane supporting base. The plane supporting base is provided with a main shaft through a bearing in a vertical supporting manner. A dirt removing scraper is fixedly arranged on the top of the main shaft in a sleeving manner and attached to the upper surface of a bottom grid barrier. Runner blades are fixedly arranged at the bottom of the main shaft in a sleeving manner. Flow converging discs are arranged on the lower bottom face of the bottom grid barrier, and water flow outlets of the flow converging discs are located over the runner blades. The dirt removing device can conveniently conduct dirt scraping treatment on the bottom grid barrier, and the dirt removing efficiency is improved; and the cleaning quality is high, manual dirt removing is replaced, and safety is improved.

Description

technical field [0001] The invention relates to a decontamination device, in particular to a bottom grid decontamination device and method. Background technique [0002] Bottom grid fence dams are generally built in mountainous areas and river sections with large gradients, with relatively few people. If the dirt on the water inlet fence is not cleaned up in time, it will affect the function and power generation efficiency of the bottom grid dam, so it is necessary to regularly clean the bottom grid. The traditional cleaning method mainly uses manual cleaning, which is inefficient, time-consuming and laborious, and inconvenient to operate. There are certain safety hazards in the manual cleaning process. At the same time, manual cleaning is not clean. Affect cleaning quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cleaning device and method for the bottom grid. Decontamination improves safety. [00...
