[0002] Wastewater treatment refers to the purification process to make wastewater meet the water quality requirements for discharge into a water body or reuse. This process is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is of great significance to protecting the water environment and maintaining ecological balance.

[0003] Among them, the internal water inlet fine grid mesh plate is one of the main pre-treatment equipment in sewage treatment plants and water plants. It is a necessary equipment in sewage treatment in sewage treatment plants and water plants. Its surface is easily blocked by debris during sewage treatment. Therefore, a surface cleaning device for the internal water inlet fine grid mesh plate of sewage treatment is needed.

[0004] At present, the surface cleaning device of the fine water grid mesh plate in the sewage treatment plant is usually driven by a motor to drive an active shaft, and the active shaft drives a double-shaped brush to rotate to clean the surface of the fine water grid mesh plate. Only rotation cleaning can only clean part of the area, and the cleaning efficiency is not high and the cleaning effect is not good. On the other hand, the double-shaped structure has only two single points to contact the mesh plate surface, which aggravates the wear and bending deformation of the brush bristles. As a result, the service life of the equipment is relatively short. Therefore, a surface cleaning device for the fine water grid mesh plate in the sewage treatment plant is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a surface cleaning device for the fine grid mesh plate in the sewage treatment plant, aiming to improve the problems in the prior art of less cleaning area due to rotation cleaning and shorter service life of the double-shaped plate brush.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a surface cleaning device for a fine grid mesh plate of an internal water inlet of a sewage treatment plant, comprising an equipment base, wherein a right supporting frame is fixedly connected to the right side of the equipment base, and a left supporting frame is fixedly connected to the left side of the equipment base, and sliding grooves are provided on the inner sides of the right supporting frame and the inner sides of the left supporting frame, and a T-shaped slot is provided on the left side of the left supporting frame, and a T-shaped block is slidably connected inside the T-shaped slot, and a power assembly is fixedly connected to the top of the T-shaped block, and a rotating shaft is fixedly connected to the top of the power assembly, and a sliding seat is fixedly connected to the inner wall of the side of the sliding seat, and a rack is meshed with a half gear on the inner side of the rack, and the bottom end of the half gear is fixedly connected to a driving bevel gear, and a passive bevel gear is meshed at the bottom of the driving bevel gear, and a rotating bracket is rotatably connected to the bottom of the driving bevel gear, and a cleaning assembly is rotatably connected to the inside of the rotating bracket.

[0007] The cleaning assembly comprises a roller shaft, the outer circumference of which is rotatably connected to the inside of the rotating bracket, and the outer circumference of which is fixedly connected to a brush.

[0008] The power assembly comprises a motor bracket, the bottom end of which is fixedly connected to the top of the T-block, a rotating motor is fixedly connected inside the motor bracket, and the top end of the rotating shaft is fixedly connected to the output shaft at the bottom end of the rotating motor.

[0009] The outer periphery of the rotating shaft is slidably connected to the inside of the sliding seat, and the bottom end of the rotating shaft is fixedly connected to the top end of the half gear.

[0010] The number of teeth of the half gear is equal to the number of teeth of the rack and is distributed on an arc surface of 135 degrees.

[0011] The left end of the roller shaft is fixedly connected to the right side of the passive bevel gear, and the outer periphery of the roller shaft is slidably connected to the inside of the slide groove.

[0012] The brushes are arranged in multiple groups and are evenly distributed in an annular shape on the periphery of the roller.

[0013] The utility model has the following beneficial effects:

[0014] 1.

[0023] Reference Figure 2-Figure 3The top of the left support frame 3 is fixedly connected with a sliding seat 10, and the outer periphery of the rotating shaft 9 is slidably connected to the inside of the sliding seat 10. The sliding seat 10 limits the rotating shaft 9 to slide forward and backward only along the inner wall of the sliding seat 10. The inner wall of the side of the sliding seat 10 is fixedly connected with a rack 11. The rack 11 is provided with two groups, which are symmetrically arranged on the left and right side walls of the sliding seat 10. A half gear 12 is meshed on the inside of the rack 11. The bottom end of the rotating shaft 9 is fixedly connected to the top of the half gear 12. The number of teeth of the half gear 12 is equal to that of the rack 11, and they are distributed on an arc surface of one hundred and thirty-five degrees. When the half gear 12 rotates, the half gear 12 meshes with the teeth of the right rack 11. The half gear 12 moves backward under the action of the right rack 11. When the half gear 12 reaches the rear end of the right rack 11, the half gear 12 12 teeth are just used up and disengaged from the right rack 11. At this time, the half gear 12 is meshed with the left rack 11 again. Under the action of the right rack 11, the half gear 12 moves forward again, so that the rotating shaft 9 slides back and forth. The bottom end of the half gear 12 is fixedly connected to a driving bevel gear 13, and a passive bevel gear 14 is meshed at the bottom of the driving bevel gear 13. The passive bevel gear 14 can convert the horizontal rotation of the driving bevel gear 13 into a vertical rotation.

[0025] Working principle: When you want to quickly clean the water inlet fine grid, turn on the rotating motor 8, the output shaft at the bottom of the rotating motor 8 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the semi-gear 12 to rotate, and the semi-gear 12 drives the rotating shaft 9 to reciprocate back and forth under the action of the rack 11. The rotating shaft 9 drives the driving bevel gear 13 to rotate and drives the driving bevel gear 13 to reciprocate back and forth. The driving bevel gear 13 drives the roller shaft 16 to reciprocate back and forth through the rotating bracket 15. At the same time, the driving bevel gear 13 drives the passive bevel gear 14 to rotate quickly, so that the roller shaft 16 rotates quickly, and the roller shaft 16 drives the brush 17 to scrub the surface of the water inlet fine grid, and the cleaning effect is good and the cleaning area is large. In order to ensure the life of the brush 17, multiple groups of brushes 17 are set on the surface of the roller shaft 16, so that the brush 17 forms a circular structure. Due to the circular structure, the entire water inlet fine grid is continuously cleaned, and the rolling structure makes the bristles not easy to wear and deform, achieving the ideal cleaning effect and extending the service life of the cleaning brush 17.
