Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and particularly relates to a sewage cleaning device for water conservancy projects. Background Art

[0002] Water conservancy projects refer to facilities that control, regulate, develop, utilize and protect natural water to reduce and eliminate water and drought disasters, and utilize water resources to meet the needs of human society and the natural environment. Water conservancy facilities include a variety of water conservancy equipment, water inlets, water wells, storage rooms, sand settling tanks, hydrological observation stations, open channels, inverted siphons, tunnels, aqueducts, overflow workers, water supply gates, drainage gates, low mountain branches, circular moats, etc. In reservoirs or rivers with a lot of dirt, in order to ensure the safe and normal operation of hydropower stations or pumping stations, it is often necessary to set up pollution cleaning devices to achieve pollution cleaning without stopping the machine or emptying the reservoir.

[0003] At present, most of the water conservancy pollution cleaning work is done by rotating gratings. Since the rotating gratings are relatively compact, it will be difficult to remove the stuck materials, resulting in work failures. Secondly, the stuck materials in the gaps between the bars are easy to deform, and the maintenance is relatively cumbersome.

[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created, and a sewage cleaning device for water conservancy projects is provided to solve the above problems.

During the movement, the circular movement of the transmission chain will realize the cleaning of the lifting type belt dirt rake. The movement of the lifting type belt dirt rake from bottom to top will automatically realize the cleaning of pollutants in the water. When the lifting type belt dirt rake is flipped over, the movement from bottom to top is converted into a top-down movement process, and the pollutants fall into the sewage collecting bin through free fall for centralized recovery.

[0010] As a preferred embodiment of a sewage cleaning device for a water conservancy project, the gate body is provided with a first guide hole corresponding to the first transmission shaft, the first transmission shaft is slidably fitted in the first guide hole, one end of the first transmission shaft extends into the first shaft seat, and the gate body is provided with a second guide hole corresponding to the second transmission shaft, the second transmission shaft is slidably fitted in the second guide hole, and both ends of the second transmission shaft extend into the second shaft seat.

[0012] As a preferred embodiment of a sewage cleaning device for a water conservancy project, connecting arms are provided at both ends of the sewage collecting bin, and the sewage collecting bin is fixedly matched with the gate body through the connecting arms.

[0013] As a preferred embodiment of a sewage cleaning device for a water conservancy project, one end of the sewage collecting bin is inclined, and a notch is provided at the inclined end of the sewage collecting bin corresponding to the rake teeth, and the size of the notch is larger than the rake teeth.

[0014] As a preferred embodiment of the sewage cleaning device for water conservancy projects, a sewage outlet is provided at one end of the sewage collecting bin.

[0015] In the above solution, the notch is used to ensure the stability of the movement of the lifting belt dirt rake.

[0016] In the above scheme, the variable frequency motor at one end of the pollutant collecting bin realizes the spiral motion of the spiral conveying body through transmission, thereby realizing the conveying and discharge of pollutants.

[0017] After adopting the above technical scheme, the beneficial effects of the utility model are: the device has a good cleaning effect, the material is not easy to get stuck during the cleaning process, and the centralized treatment of pollutants can be achieved.

[0018] The process of circular motion of the transmission chain is to realize the cleaning of the lifting type dirt rake. The upward movement of the lifting type dirt rake will automatically clean the pollutants in the water. When the lifting type dirt rake is turned over, the movement from bottom to top is converted into a top-down movement process. At this time, the pollutants fall into the dirt collecting bin below by free fall for centralized recovery. The centralized collected pollutants are discharged under the spiral conveying of the spiral conveying body to avoid blockage of the dirt collecting bin. BRIEF DESCRIPTION OF THE DRAWINGS
