[0003] Existing river debris interception devices require the gates to be removed for repair when damaged, and the debris trapped in the middle of the river is difficult to clean. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a river debris interception device for water conservancy design, which can be quickly inspected and repaired and can bring garbage in the water to the surface or shallower areas.

[0005] A river debris interception device for hydraulic design includes a dam body located on both sides of a river channel, and further includes: a support shaft mounted on the dam body; a rotating frame rotatably connected to both ends of the support shaft, the rotating frame being slidably connected to the inner wall of the dam body; a vertical shaft located at the front end of the rotating frame; several horizontal bars fixed to the vertical shaft; several floating buckets slidably connected to the horizontal bars, with gaps between the upper and lower floating buckets; a limiting frame located at the rear end of the rotating frame; and an opening and closing mechanism for restricting the movement of the limiting frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 As shown, a river pollution interception device for hydraulic design includes a dam body 1, which is located on both sides of a river channel. It also includes: a support shaft 2 mounted on the dam body 1; a rotating frame 3 rotatably connected to both ends of the support shaft 2, the rotating frame 3 being slidably connected to the inner wall of the dam body 1; a vertical shaft 4 located at the front end of the rotating frame 3; several horizontal bars 5 fixed to the vertical shaft 4; several floating buckets 6 slidably connected to the horizontal bars 5, with gaps between the upper and lower floating buckets 6; a limiting frame 7 located at the rear end of the rotating frame 3; and an opening and closing mechanism 8 for restricting the movement of the limiting frame 7.

[0025] The dam body 1 is provided with a base 11, and the two ends of the support shaft 2 are fixed to the base 11. The support shaft 2 spans the river channel, and the two bases 11 fix the position of the support shaft 2. The surface of the support shaft 2 is painted or electroplated for rust prevention to prevent the support shaft 2 from rusting during its service life.

[0026] The rotating frame 3 is L-shaped. One side wall of the rotating frame 3 is attached to the inner wall of the dam body 1, and the support shaft 2 passes through this side wall. The rotating frame 3 rotates relative to the support shaft 2. The other side wall of the rotating frame 3 is perpendicular to the inner wall of the dam body 1. This side can resist the flow of water and prevent water from flowing through this side. At the same time, it can prevent dirt and garbage in the river from flowing through the rotating frame 3, thus achieving the effect of intercepting pollution.

[0027] The rotating frame 3 has a connecting block 31 protruding from its front end. The top of the vertical shaft 4 is fixed to the connecting block 31 by welding. The vertical shaft 4 rotates together with the rotating frame 3. When the vertical shaft 4 is in a vertical state, the bottom of the vertical shaft 4 is located below the water surface of the river channel, and the bottom of the vertical shaft 4 does not contact the bottom of the river channel. This ensures that the device can intercept floating garbage in the river channel and the middle part, but the bottom of the river channel does not affect the rotation of the rotating frame 3 and the vertical shaft 4.

[0028] The horizontal bars 5 are arranged vertically on the side wall of the vertical axis 4, with the distance between adjacent horizontal bars 5 being the same. One end of each horizontal bar 5 is welded to the side wall of the vertical axis 4, and the length of each horizontal bar 5 is half the length of the river channel. Two horizontal bars 5 can run through the entire river channel. The other end of each horizontal bar 5 is equipped with a limiting plate 51, which is connected to the end of the horizontal bar 5 by welding or screwing. The diameter of the limiting plate 51 is larger than the diameter of the horizontal bar 5. The limiting plate 51 prevents the floating barrel 6 from slipping off the horizontal bar 5. When it is necessary to quickly remove or repair the floating barrel 6, the limiting plate 51 can be cut or removed by screwing.

[0029] The floating bucket 6 has buoyancy and tends to move upwards when it is in the water. For example... Figure 3 As shown, the floating bucket 6 includes two semicircular blocks 61 and a connecting ring 62. The semicircular blocks 61 are hollow plastic buckets that can float on the water surface. The two semicircular blocks 61 can be fitted together to form a circular tube. The connecting ring 62 connects the two ends of the two semicircular blocks 61 and fixes the two semicircular blocks 61 together. The connecting ring 62 is inserted into the crossbar 5 before the limiting plate 51 is installed.

[0030] The middle part of the semicircular block 61 slides on the crossbar 5 and also rotates around the crossbar 5 as an axis. Both ends of the semicircular block 61 are provided with threaded tubes 611, which protrude from the sidewalls of the semicircular block 61. After two semicircular blocks 61 are joined together, the threads on the threaded tubes 611 are connected. At this time, the connecting rings 62 are screwed onto the threaded tubes 611, connecting the two semicircular blocks 61 together, allowing the float bucket 6 to move on the crossbar 5. The overall length of the float bucket 6 after installation is slightly less than the length of the crossbar 5. If the semicircular block 61 is damaged by sharp debris or other objects, there is space to unscrew the two connecting rings 62 from the threaded tubes 611, thus separating and replacing the two semicircular blocks 61. If the connecting rings 62 are damaged, the limiting plate 51 needs to be removed and a new connecting ring 62 needs to be fitted.

[0031] After the floating buckets 6 are installed on the crossbar 5, water flows through the gaps between the floating buckets 6, while garbage and filth in the river are intercepted by the floating buckets 6, reducing the amount of garbage and filth passing through the water in this device. The surface area of ​​the intercepted garbage is larger than the area of ​​the gaps; garbage and filth that are too small will pass through the gaps along with the water.

[0032] The limiting frame 7 includes an extension plate 71 and a positioning rod 72. The extension plate 71 is located at the rear end of the rotating frame 3 and is parallel to the dam body 1. The positioning rod 72 is fixed to the top surface of the extension plate 71. The positioning rod 72 and the extension plate 71 rotate together with the rotating plate. When the vertical axis 4 is in a vertical state, the positioning rod 72 is vertically upward and located behind the support shaft 2. The extension plate 71 and the positioning rod 72 will not conflict with the support shaft 2 when they rotate.

[0033] The opening and closing mechanism 8 is used to adjust the rotation angle of the rotating plate. The opening and closing mechanism 8 includes a sliding frame 81, a hydraulic rod 82, and a blocking rod 83. The sliding frame 81 is fixed to the top of the dam body 1, and has openings on its side walls and at both ends. The blocking rod 83 is slidably connected to the sliding frame 81, with its end protruding from the sliding frame 81. The telescopic end of the hydraulic rod 82 is fixed to the blocking rod 83, and the hydraulic rod 82 pushes the blocking rod 83 to move along the river channel. The fixed end of the hydraulic rod 82 is fixed to the dam body 1. The hydraulic rod 82 uses existing technology, powered by a hydraulic pump.

[0034] The protruding part of the blocking rod 83 fits against the positioning rod 72, and the blocking rod 83 is perpendicular to the positioning rod 72. The blocking rod 83 and the positioning rod 72 slide against each other. When the blocking rod 83 pushes the positioning rod 72 into a vertical position, the rotating frame 3 is also in a vertical position on the vertical axis 4. At this time, the floating bucket 6 can intercept river garbage and dirt over the largest area. Figure 4 As shown, when it is necessary to remove garbage from the water or replace a partially damaged float 6, the telescopic end of the hydraulic rod 82 is moved backward. Under the buoyancy of the float 6, the float 6 moves the crossbar 5 and the bogie upward, thereby bringing the intercepted garbage and the damaged float 6 to the surface. The blocking rod 83 limits the rotation angle. After cleaning and maintenance are completed, the hydraulic rod 82 is pushed forward to restore the device to the interception state.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
