Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dam floating debris removal, and relates to a dam floating debris removal device. Background Technology
[0002] Existing dams are water-retaining structures that block the flow of water in rivers and canals to raise water levels or regulate flow. They can form reservoirs, raise water levels, regulate runoff, and concentrate water head for purposes such as flood control, water supply, irrigation, hydroelectric power generation, and improved navigation. River regulation structures that adjust river course and protect riverbanks are also called dams, such as groynes, longitudinal dams, and submerged dams. Dams are generally built in relatively remote areas. For some small civilian water dams, which are often used for irrigation or drinking water sources, floating debris on the water surface can easily lead to changes in water quality if not cleaned in a timely manner. Existing dam floating debris cleaning devices generally require external power for operation. In remote areas, laying electrical circuits is costly, resulting in high operating costs.
[0003] Therefore, this utility model provides a device for cleaning floating debris from dams, which solves the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses a dam floating debris cleaning device. The technical solution adopted is as follows: A dam body is provided, with a baffle installed at an opening on the dam body. Several guide holes are evenly opened on the upper edge of the baffle. Notches are opened downwards on both sides of the top of the baffle. Bushing seats are fixedly installed on the front and rear sides of the right side wall of the front and rear notches. A rotating shaft is movably inserted into the front and rear bushing seats via bearings. Bushings are fixedly fitted onto the rotating shafts at positions directly opposite the front and rear notches. A cleaning mechanism is fixedly installed on the top of the front and rear bushings. The cleaning mechanism includes a reinforcing frame fixedly connected to the top of the rotating shaft. The reinforcing frame is located on the right side of the bushing, bent downwards and then extended horizontally. The upper part of the bent portion of the front and rear reinforcing frames is fixedly connected to both ends of the guide plate. A first filter screen is fixedly installed on the horizontal end of the right side of the guide plate. A counterweight plate is fixedly connected to the left end of the front and rear reinforcing frames. A second filter screen is fixedly installed on the front and rear frame walls on the right side of the counterweight plate. A water storage bag is installed on the lower part of the second filter screen. A liquid guide tube is fixedly inserted into the front edge of the second filter screen. The liquid guide tube is fixedly laid along the upper part of the front reinforcing frame to its right end. A funnel is fixedly connected to the right end of the liquid guide tube. A filter screen is set at the opening of the funnel.
[0005] As a preferred embodiment of this utility model, the front and rear widths of the bushing and the front and rear widths of the reinforcing frame are both smaller than the opening width of the notch. This design ensures that the bushing and the reinforcing frame will not interfere with the corresponding notch when rotating to the left around the pivot axis, and ensures that the reinforcing frame can be flipped to the left at a large angle, so that the water storage bag can contact and squeeze with the guide plate, squeezing out the water inside through the second filter screen.
[0006] As a preferred embodiment of this utility model, inclined support rods are fixedly installed on the lower side walls of the bent sections of the front and rear reinforced frames, and the lower ends of the inclined support rods abut against the right side wall of the baffle. When the water storage bags and the first filter screen of the front and rear reinforced frames are in an unloaded state, the weight of the left half of the front and rear reinforced frames is less than the weight of the right half. This design can ensure that after the floating objects are poured out, the front and rear reinforced frames can be flipped to the right and restored to their original positions.
[0007] As a preferred embodiment of this utility model, inclined support frames are fixedly installed on the front and rear sides of the left side wall of the baffle, and guide plates are fixedly installed on the upper part of the inclined arms of the front and rear inclined support frames. The horizontal arms of the front and rear inclined support frames have slots. By using guide plates, it is convenient to guide the floating objects that are tilted down from the first filter plate into the storage tank below for collection.
[0008] As a preferred embodiment of this utility model, a storage trough is movably mounted inside the front and rear bayonets, and the right side wall of the storage trough is inclined and attached to the lower end of the surface of the guide plate.
[0009] As a preferred embodiment of this utility model, drainage holes are evenly provided at the bottom of the storage tank.
[0010] The beneficial effects of this utility model are as follows: By designing a cleaning mechanism that can rotate around a pivot on a baffle, the cleaning mechanism collects floating debris flowing into the area around the baffle through a first filter screen on the right side. Water is then introduced into a water storage bag on the left side through a funnel. When the water level in the storage bag reaches a certain point, the counterweight plate on the left moves downward, causing the floating debris on the right side to be lifted upward as the first filter screen rotates. The debris is then poured onto a guide plate on the left side of the baffle, allowing it to flow down into a storage trough for easy collection by cleaning personnel. As the water storage bag rotates downward, it is squeezed against the guide plate, causing the water inside to be discharged through a second filter screen. Due to the reduced weight on the left side of the reinforced frame, the weight on the right side is greater than that on the left, causing the frame to rotate back to its original position on the right side for the next collection and cleaning cycle. This cycle repeats continuously without the need for external power, achieving periodic rotation, pouring, and collection, thus improving the energy efficiency of the device in the field.

Detailed Implementation
[0016] Example 1
[0017] like Figures 1 to 4As shown, the dam floating debris cleaning device of this utility model adopts the following technical solution: It includes a dam body 1, with a baffle 11 installed on the opening of the dam body 1. Several guide holes 111 are evenly opened on the upper edge of the baffle 11. Notches 112 are respectively opened downwards on both sides of the top of the baffle 11. Bushing seats 12 are respectively fixedly installed on the front and rear sides of the right side wall of the front and rear notches 112. A rotating shaft 13 is movably inserted into the front and rear bushing seats 12 through bearings. Bushing 13 is fixedly fitted onto the rotating shaft 13 at positions directly opposite the front and rear notches 112. 4. A cleaning mechanism 2 is fixedly installed on the top of the front and rear bushings 14. The cleaning mechanism 2 includes a reinforcing frame 21 fixedly connected to the top of the rotating shaft 13. Inclined support rods 211 are fixedly installed on the lower sidewalls of the bent sections of the front and rear reinforcing frame 21. The lower ends of the inclined support rods 211 abut against the right sidewall of the baffle 11. The front-to-back width of the bushing 14 and the front-to-back width of the reinforcing frame 21 are both smaller than the opening width of the notch 112. The reinforcing frame 21 is located on the right side of the rotating shaft 13, bent downwards and then extends horizontally. The upper parts of the bent portions of the front and rear reinforced frame 21 are fixedly connected to both ends of the guide plate 22. A first filter screen plate 23 is fixedly installed on the horizontal end of the right side of the guide plate 22. A counterweight plate 24 is fixedly connected to the left end of the front and rear reinforced frame 21. A second filter screen plate 25 is fixedly installed on the front and rear frame walls on the right side of the counterweight plate 24. A water storage bag 26 is installed on the lower part of the second filter screen plate 25. A liquid guide tube 27 is fixedly inserted into the front edge of the second filter screen plate 25. The liquid guide tube 27 is fixed along the upper part of the front reinforced frame 21. The right end of the liquid guide tube 27 is fixedly connected to the funnel 28. A filter screen 29 is provided at the opening of the funnel 28. Inclined support frames 3 are fixedly installed on the front and rear sides of the left side wall of the baffle 11. A guide plate 31 is fixedly installed on the upper part of the inclined arm of the front and rear inclined support frames 3. A slot 32 is opened on the horizontal arm of the front and rear inclined support frames 3. A storage tank 4 is movably locked in the slot 32. The right side wall of the storage tank 4 is inclined to fit against the lower end of the surface of the guide plate 31. Drainage holes 41 are evenly opened at the bottom of the storage tank 4.
[0018] When the water storage bag 26 and the first filter screen 23 of the front and rear reinforced frame 21 are all in an unloaded state, the weight of the left half of the front and rear reinforced frame 21 is less than the weight of its right half.
[0019] The working principle of this utility model is as follows: During use, due to the guide holes 111 opened on the upper edge of the baffle 11, impurities floating on the water surface of the dam 1 are carried by the water flow and drift to the first filter screen plate 23 below the water surface on the right side of the baffle 11. At the same time, the funnel 28 gradually pours water into the water storage bag 26 through the liquid guide pipe 27. As the weight of the water in the water storage bag 26 increases, when it increases to a certain level, the counterweight plate makes the weight of the left half of the reinforcing frame 21 greater than that of the right half, thereby strengthening the frame. The frame 21 flips to the left, causing the floating objects on the first filter screen 23 to be poured onto the guide plate 31, and then slide down into the storage tank 4 for centralized collection. As it flips to the left, the water storage bag 26 is squeezed between itself and the guide plate 31, squeezing out the water inside through the second filter screen 25. This makes the weight of the left half of the reinforced frame 21 less than that of the right half, allowing the reinforced frame 21 to flip to the right and return to its original position for another cleaning operation. The entire process requires no external power supply.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
