Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a trash grille for water conservancy projects. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. During the construction of water conservancy projects, large volumes of impurities on the water surface are intercepted by placing trash racks.

[0003] After searching, a kind of pollution interception device for water conservancy projects with announcement number CN215441798U includes a pollution interception grid plate, a first threaded rod is rotatably connected between the top and the bottom of one side of the pollution interception grid plate; a lifting frame matched with the pollution interception grid plate is threadedly connected to the side surface of the first threaded rod; a linear array between the two end sides of the lifting frame is provided with a pollution guide frame; a second threaded rod is rotatably connected between the two ends of the top of the pollution interception grid plate; a sewage discharge plate matched with the sewage guide frame is threadedly connected to the side surface of the second threaded rod. The utility model drives the lifting frame to move upward when the first threaded rod rotates, so that the sewage guide frame moves upward the garbage floating objects intercepted by the side of the pollution interception grid plate, and drives the sewage discharge plate to discharge the garbage floating objects on multiple sewage guide frames to the top end surface of the pollution interception grid plate when the second threaded rod rotates. It has a high degree of automation, reduces the intensity of manual labor, and is highly practical.

[0004] Based on the above patent, through the coordinated use of the sewage grid plate, the lifting frame, the sewage guide frame and the sewage plate, when the first threaded rod rotates under the action of the second servo motor, it drives the lifting frame to move upward, so that the sewage guide frame moves up the garbage floating objects intercepted by the side of the sewage grid plate, and when the second threaded rod rotates under the action of the first servo motor, it drives the sewage plate to discharge the garbage floating objects on multiple sewage guide frames to the top end surface of the sewage grid plate. The degree of automation is high, the intensity of manual labor is reduced, and the practicality is strong. However, the sewage guide frame of the device is driven by the threaded rod and can only go straight up and down. If garbage is intercepted by the grid plate during the garbage cleaning process, the sewage guide frame will push the garbage to accumulate at the bottom of the river channel when it is reset. This part of the garbage is difficult to clean and affects the subsequent reset of the sewage guide frame. Utility Model Content

[0025] Specifically, when cleaning, the electric push rod 10 is started to contract so that the push plate 18 on the fixed plate 17 is inserted into the through hole 2, and then the motor 2 14 is started to drive the threaded rod 2 15 to rotate, and with the cooperation of the guide rod 16, the fixed plate 17 is moved upward along the guide rod 16, prompting the push plate 18 to move upward along the inside of the through hole 2 to drive the garbage intercepted by the grid plate 1 to move toward the water surface. After all the garbage is cleaned up, the electric push rod 10 is started again to move the push plate 18 out of the through hole 2, and then the motor 2 14 is started again to reverse and reset the fixed plate 17, so as to avoid the new garbage intercepted by the grid plate 1 at the bottom of the push plate 18 during the garbage cleaning process, which will cause the push plate 18 to be pressed to the bottom of the river channel and unable to be cleaned when it is reset. If the accumulation is too high, it will also affect the movement of the push plate 18.

[0026] The left and right sides of the top of the grid plate 1 are fixedly connected with fixed blocks 27, the left end of the left fixed block 27 is fixedly connected with a motor 18, the driving end of the motor 18 is fixedly connected with a threaded rod 15, the outer wall of the threaded rod 15 is rotatably connected to the inner wall of the fixed block 27, the outer wall of the threaded rod 15 is threadedly connected with a slider 6, the bottom end of the slider 6 is slidably connected to the top of the grid plate 1, the bottom end of the slider 6 is fixedly connected with a scraper 9, the inner wall of the scraper 9 is slidably connected to the outer wall of the slide rod 4, the left and right ends of the slide rod 4 are fixedly connected with fixed blocks 3, and the rear ends of the fixed blocks 3 are fixedly connected to the front end of the grid plate 1;

[0027] Specifically, when the garbage blocked by the grid plate 1 is driven by the push plate 18 to float to the water surface, the motor 8 is started to drive the threaded rod 5 to rotate, so that the slider 6 moves through the scraper 9 to push the garbage to the shore, which is convenient for workers to clean up.

When the garbage blocked by the grid plate 1 is driven by the push plate 18 to float to the water surface, the motor 18 is started to drive the threaded rod 15 to rotate, so that the slider 6 moves through The scraper 9 pushes the garbage to the shore to facilitate workers to clean it up.
