Description

Technical Field

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

[0002] Water conservancy projects are projects built to control surface or underground water resources in order to efficiently allocate water resources. Water conservancy projects include the construction of dams, channels, ferries and other types of hydraulic structures. All types of hydraulic structures need to be transported using water pipelines, and impurities and garbage in the water need to be cleaned during the water delivery process to facilitate further utilization of water resources. The existing filtering device has a single structure. When cleaning the filtering mechanism, it is necessary to close the valve and stop the water delivery. The complicated operating steps lead to low cleaning and maintenance efficiency of the filtering mechanism. In addition, during the cleaning process, there is a problem of water leakage through gaps, and it is even more necessary to cut off the water supply, resulting in reduced efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a drainage filter frame for water conservancy projects, which is used to overcome the above-mentioned defects in the prior art.

[0005] The beneficial effects of the utility model are:

[0006] Through the abutment between the sealing baffle and the filter belt, water flows in through the opened discharge port during the discharge process, preventing water from leaking from the side wall gap between the filter belt and the fixed frame. Through the rotation of the cleaning brush in the filter belt, during the rotation of the filter belt, the abutment sealing plate blocks debris from entering the inner end of the filter belt through the cleaning brush, preventing contamination of the inner end of the filter belt. The cleaning brush cleans debris on the filter belt, thereby keeping the filter holes unobstructed and preventing blockage. No manual cleaning is required, reducing work intensity.

[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a drainage filter frame for a water conservancy project includes a first fixed plate 10, a fixed frame 12 opened front and back is provided in the first fixed plate 10, an openable discharge port 11 is provided on the first fixed plate 10, two fixed frames 15 distributed front and back are fixedly provided at the right end of the fixed frame 12, a power motor 16 is fixedly provided on the two fixed frames 15, a driving wheel 17 is connected to the left end of the power motor 16, a driven wheel 18 is rotatably connected to the two fixed frames 15, the driving wheel 17 is meshed with the driven wheel 18, two groups of roller groups 20 are rotatably connected in the fixed frame 12, the roller groups 20 are distributed up and down, a filter belt 21 is provided on the roller groups 20, and filter holes 22 evenly distributed are opened on the filter belt 21, the right end of the roller group 20 extends to the right and penetrates the fixed frame 12, the roller group 20 is located at the right end of the fixed frame 12 and is connected with a transmission belt 19, the driven wheel 18 is meshed with the driven wheel 18, A cleaning brush 23 is fixedly arranged at the left end, which is located in the fixed frame 12 and abuts against the inner end surface of the filter belt 21. The driven wheel 18 and the driving wheel 17 are distributed up and down, and the radius of the driven wheel 18 is smaller than the radius of the driving wheel 17. Abutting sealing plates 24 are arranged at the upper and lower ends of the cleaning brush 23. Two groups of front-to-back distributed sealing baffles 25 are fixedly arranged in the fixed frame 12, and the sealing baffles 25 are distributed left and right. The sealing baffles 25 are fixedly connected to the abutting sealing plates 24 at the lower end and abut and seal with the roller group 20 at the upper end. The front and rear ends of the sealing baffles 25 are tightly attached to the inner end surface of the filter belt 21, and the left and right ends of the abutting sealing plates 24 are fixedly connected to the sealing baffles 25. A detachable second fixing plate 13 is fixedly arranged at the left end of the fixed frame 12, and the second fixing plates 13 are distributed front and back. Two front-to-back symmetrical garbage frames 14 are fixedly arranged at the right ends of the two second fixing plates 13, and the openings of the garbage frames 14 are arranged upward.

[0020] The two filter belts 21 distributed front and back are prevented from being placed on the two sets of roller groups 20, and the filter belts 21 are kept tensioned by the roller groups 20 so that the filter belts 21 can abut against the sealing baffle 25. The second fixing plate 13 is installed at the box fixing frame 12, and the second fixing plate 13 is connected to the garbage frame 14 end and is set to the right, and inserted into the fixing frame 12 so that the second fixing plate 13 abuts against the left end surface of the fixing frame 12, and is fixed by a block. The two garbage frames 14 distributed front and back are located at the front and rear ends of the filter belt 21 and abut against the outer end surface of the filter belt 21. The fixing frame 12 is installed and placed in the first fixing plate 10, as shown in FIG. Figure 1 As shown;

[0021] During excretion, the discharge port 11 is opened, and the water flow blocked by the first fixed plate 10 flows into the fixed frame 12 through the discharge port 11, and is filtered by two filter belts 21 distributed front and back in the fixed frame 12, and the water flow flows backward through the evenly distributed filter holes 22. The filter belt 21 is set as at least a front and back double-layer setting, and the water flow flows backward after being filtered by the double-layer filter belt 21. During the filtering process, the debris in the water flow will adhere to the outer end surface of the filter belt 21 and the side wall of the filter hole 22;

[0022] When cleaning the filter belt 21, the power motor 16 fixedly arranged on the two fixing frames 15 is controlled to work, and the power motor 16 controls the power end to rotate, so that the rotating rod connected to the power end of the power motor 16 rotates, and the rotating rod at the upper end is synchronously driven to rotate in the same direction under the connection of the transmission belt 19. Under the fixed connection between the rotating rod and the roller group 20, the roller group 20 located in the fixed frame 12 is driven to rotate, and the roller group 20 drives the filter belt 21 to move, for example Figure 5 As shown, the power motor 16 controls the upper and lower roller groups 20 to rotate clockwise to push the filter belt 21 to move, with the left end of the filter belt 21 pointing upward and the right end pointing downward. Similarly, during the rotation process, the power rod at the power motor 16 synchronously drives the fixedly connected driving wheel 17 to rotate, and the driving wheel 17 synchronously drives the driven wheel 18 to rotate in the opposite direction under the meshing with the driven wheel 18. Through the transmission ratio between the driving wheel 17 and the driven wheel 18, the cleaning brush 23 fixedly connected to the driven wheel 18 rotates counterclockwise, and the rotation speed of the cleaning brush 23 is accelerated. The debris attached to the outer end surface of the filter belt 21 falls into the garbage frame 14 at the rear end after abutting with the garbage frame 14 at the rear end, and the debris located at the filter hole 22 can fall into the front and rear garbage frames 14 for collection through the rotation of the cleaning brush 23, completing the cleaning of the filter belt 21, and the abutting sealing plate 24 prevents the debris from passing through the cleaning brush 23 to enter the inner end part of the filter belt 21.

[0023] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
