Description

Technical Field

[0001] The utility model relates to the technical field of trash racks, in particular to a self-cleaning dam anti-pollution trash rack. Background Art

[0002] During the daily operation of a dam, the water flow often carries a large amount of impurities, such as branches, plastic bags, floating logs, etc. If these impurities are not cleaned up, they are likely to accumulate at the gate, resulting in blocked water flow, affecting the normal operation of the dam, and even potentially causing safety hazards. To protect the normal operation of the dam, a trash rack is usually set in front of the gate to intercept large impurities in the water. However, after the existing trash rack is used for a period of time, a large amount of impurities will accumulate on the net surface, affecting the water flow. Therefore, it needs to be cleaned regularly. However, the traditional cleaning method usually relies on manual operation, which is not only time-consuming and laborious, but also has certain safety risks. Summary of the Utility Model

[0005] The cleaning mechanism includes a sewage collection box, a lifting module and a transverse movement module. The sewage collection box is slidably connected to one side of the trash rack in the dam opening. One side of the sewage collection box is in contact with the trash rack. A collection port is arranged on the top surface of the sewage collection box. A sewage discharge port is arranged on one end side of the sewage collection box. The sewage collection box is provided with mesh holes. When the sewage collection box is located in the dam opening, the sewage discharge port is in contact with the side wall of the dam opening.

[0008] A connecting frame is fixedly connected to the gantry, and the sliding column is fixedly connected to the connecting frame.

[0009] In the above technical solution, the lifting module includes a first motor, a winding wheel, and a lifting rope. The winding wheel is rotatably connected to the gantry, the first motor is fixedly connected to the gantry, the first motor is power-connected to the winding wheel, the lifting rope is fixedly connected to the winding wheel, a rope opening is provided on the gantry corresponding to the winding wheel, and the lifting rope passes through the rope opening and is fixedly connected to the sewage collection tank.

When it is necessary to clean the impurities attached to the trash rack, the lifting module can be used to drive the sewage collection tank to descend into the water, and then the lifting module can be used to drive the sewage collection tank to rise again. The rising sewage collection tank can collect the impurities attached to the trash rack and the surrounding impurities inside.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 —5, a self-cleaning dam anti-pollution trash rack, including a dam body 100, a dam opening 101 is provided on the dam body 100, a gate 200 is provided at the position of the dam opening 101, and by opening the gate 200, the water stored inside the dam can flow out through the dam opening 101. In order to intercept impurities (such as branches, plastic bags, floating logs, etc.) in the water, a trash rack 300 is provided in front of the gate 200 at the dam opening 101. In order to facilitate the cleaning of the trash rack 300 to avoid the accumulation of a large amount of impurities and affect the water flow, a cleaning mechanism is provided on the dam to match the trash rack 300;

[0021] Specifically, the cleaning mechanism includes a sewage collection tank 400, a lifting module 500, and a transverse movement module 600. That is, a sliding column 700 is fixedly connected inside the dam opening 101. A sliding ear 401 is fixedly connected to the sewage collection tank 400 corresponding to the sliding column 700. The sliding ear 401 is slidably connected to the sliding column 700. One side of the sewage collection tank 400 abuts against the cross-section of the trash rack 300. In addition, a collection port 402 is provided on the top surface of the sewage collection tank 400, and a sewage discharge port 403 is provided on one end side of the sewage collection tank 400. The sewage collection tank 400 is also provided with mesh holes 404. When the sewage collection tank 400 is located inside the dam opening 101, the sewage discharge port 403 abuts against the side wall of the dam opening 101, thus closing the sewage discharge port 403. Furthermore, a gantry 800 is fixedly connected to the dam corresponding to the dam opening 101, and a lifting module 500 and a transverse movement module 600 are fixedly connected to the gantry 800. The lifting module 500 here is matched with the sewage collection tank 400, so that the lifting module 500 can drive the sewage collection tank 400 to lift and lower. The transverse movement module 600 includes a sewage pushing plate 601 capable of transverse movement, and the sewage pushing plate 601 corresponds to the sewage collection tank 400. Moreover, a connecting frame 701 is fixedly connected to the gantry 800, and a sliding column 700 is fixedly connected to the connecting frame 701 to ensure that there is no limit to the sliding area of the sliding column 700;

[0022] Furthermore, the above-mentioned lifting module 500 includes a first motor 501, a winding wheel 502, and a lifting rope 503. The winding wheel 502 is rotatably connected to the gantry 800. The first motor 501 is fixedly connected to the gantry 800, and the first motor 501 is power-connected to the winding wheel 502. The lifting rope 503 is fixedly connected to the winding wheel 502. A rope opening 504 is provided on the gantry 800 corresponding to the winding wheel 502. The lifting rope 503 passes through the rope opening 504 and is fixedly connected to the sewage collection tank 400. In this way, the first motor 501 can drive the winding wheel 502 to rotate, so that the winding wheel 502 winds out or winds in the lifting rope 503, thereby realizing the lifting and lowering movement of the sewage collection tank 400. In addition, a pulley is rotatably connected at the rope opening 504, and the lifting rope 503 cooperates with the pulley to reduce the wear of the lifting rope 503;

[0023] Furthermore, the transverse movement module includes a transverse movement table 602, a lead screw 603, a limit post 604, and a second motor 605. The limit post 604 is fixedly connected to the gantry 800. The transverse movement table 602 is slidably connected to the limit post 604. The lead screw 603 is threadedly connected to the transverse movement table 602. The second motor 605 is fixedly connected to the gantry 800, and the second motor 605 is power-connected to the lead screw 603. A traction frame 606 is fixedly connected to the transverse movement table 602, and a sewage pushing plate 601 is fixedly connected to the traction frame 606. In this way, the second motor 605 can drive the lead screw 603 to rotate, so that the transverse movement table 602 performs a linear movement on the limit post 604, and then the transverse movement table 602 drives the sewage pushing plate 601 to perform a linear movement;

[0024] In summary, when the gate 200 is opened to allow the water in the dam to flow out through the dam opening 101, the trash rack 300 can intercept large impurities in the water, thereby preventing the impurities from flowing into the lower river and protecting the ecology. When it is necessary to clean the impurities attached to the trash rack 300, the lifting module 500 can be used to drive the sewage collection box 400 to descend into the water, and then the lifting module 500 drives the sewage collection box 400 to rise again. The rising sewage collection box 400 can collect the impurities attached to the trash rack 300 and the surrounding impurities inside. When the sewage collection box 400 rises out of the water surface, the water in the sewage collection box 400 can be discharged through the mesh holes 404. When the sewage collection box 400 continues to rise and the sewage collection box 400 is separated from the dam opening 101, at this time, the sewage discharge port 403 is exposed to the outside, and the sewage pushing plate 601 penetrates into the sewage collection box 400. Finally, the transverse movement module drives the sewage pushing plate 601 to perform a linear movement, so as to push the impurities in the sewage collection box 400 out through the sewage discharge port 403.
