Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically a winch for controlling blue-green algae in reservoirs. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects. In order to improve the water quality of reservoirs, it is often necessary to regularly dredge and clean up blue-green algae in the reservoirs. At this time, a winch is needed in conjunction with other dredging structures and equipment.

[0003] The existing utility model patent with authorization announcement number CN220165693U discloses a winch, including a base, a drum, a motor drive device, a sliding coupling, and a shift fork mechanism. The drum is rotatably mounted on the base via a rotating shaft, with the right end of the rotating shaft extending out of the drum. The motor drive device is mounted on the base, and the output end of the motor drive device is connected to the right end of the rotating shaft via the sliding coupling. The shift fork mechanism is connected to a second connecting sleeve to drive the second connecting sleeve to separate or engage with the first connecting sleeve. It achieves separation and connection between the motor drive device and the drum through the sliding coupling, thereby improving the speed of the drum winding and unwinding the wire rope and avoiding damage to the motor due to frequent starts and stops.

[0004] While the above technical solution can avoid damage to the motor due to frequent starts and stops, it is inconvenient to adjust the suspension position of the steel rope when reeling in and out, and the lack of a steel rope suspension position adjustment structure makes it difficult to collect blue-green algae in different distances.

[0005] Therefore, those skilled in the art have provided winches for the treatment of cyanobacteria in reservoirs to solve the problems mentioned in the background section. Utility Model Content

[0006] The purpose of this invention is to provide a winch for treating blue-green algae in reservoirs, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A winch for controlling blue-green algae in reservoirs includes a base, the upper surface of which is fixedly connected to the main body of the winch, and a suspension point adjustment mechanism is provided above the base.

[0009] The suspension point adjustment mechanism includes a steel frame, a first bracket fixedly connected to the upper surface of the steel frame, a hydraulic jack fixedly connected to the inner wall of the steel frame, a rotating shell disposed above the steel frame, an extension frame slidably connected inside the rotating shell, a servo motor fixedly connected to the inner wall of the rotating shell, a threaded rod fixedly connected to the output end of the servo motor, a second bracket fixedly connected to the front of the rotating shell, a rotating block rotatably connected to the outer surface of the second bracket, a side guide wheel fixedly connected to the back of the rotating shell, and an inclined guide wheel fixedly connected to the upper surface of the extension frame.

[0010] As a further embodiment of this utility model: the bottom surface of the steel frame is fixedly connected to the upper surface of the base, the inner wall of the rotating shell is rotatably connected to the outer surface of the first bracket, the outer surface of the threaded rod is threadedly connected to the inner wall of the extension frame, the telescopic end of the hydraulic jack is fixedly connected to the outer surface of the rotating block, and mounting plates are fixedly connected to both sides of the base, with several identical mounting holes opened on the upper surface of each mounting plate.

[0011] As a further improvement of this utility model: two handle supports are fixedly connected to both sides of the base, and a pull rod is fixedly connected to the inner wall of each handle support.

[0012] As a further improvement of this utility model: each of the handle supports is provided with a grip inside, and the inner wall of each grip is rotatably connected to the outer surface of the pull rod.

[0013] As a further improvement of this utility model: both sides of the extension frame are fixedly connected to limit sliders, and the outer surface of each limit slider is slidably connected to the inside of the rotating shell.

[0014] As a further embodiment of this utility model: the outer surface of the output end of the servo motor is fixedly connected to a coupling, and the inner wall of the coupling is fixedly connected to the outer surface of the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the cooperation of a base, a winch body, a steel frame, a first support, a hydraulic jack, a rotating shell, a second support, a rotating block, an extension frame, a servo motor, a threaded rod, an inclined guide wheel, and a side guide wheel. The hydraulic jack can extend and retract, and with the rotating block rotating around the second support, the rotating shell can pitch around the outer surface of the first support. Furthermore, the servo motor, when energized, controls the threaded rod to rotate forward and backward, allowing the extension frame to slide relative to the rotating shell. With the assistance of the side guide wheel, the inclined guide wheel can suspend the steel rope wound on the winch body at different distances. This facilitates the retrieval of blue-green algae from different distances after the steel rope on the winch body is suspended from the retrieval container, avoiding the problem of difficulty in retrieval of blue-green algae from different distances due to the lack of a steel rope suspension position adjustment structure.

[0024] Please see Figure 1-6The winch for controlling blue-green algae in reservoirs includes a base 1. A winch body 2 is fixedly connected to the upper surface of the base 1. The winch body 2 is a relatively mature structure in the existing technology, which can wind or release the steel rope wound on it under electric conditions. A suspension point adjustment mechanism 3 is set above the base 1. The suspension point adjustment mechanism 3 includes a steel frame 301. A first support 302 is fixedly connected to the upper surface of the steel frame 301. A hydraulic jack 303 is fixedly connected to the inner wall of the steel frame 301. The bottom surface of the steel frame 301 is fixedly connected to the upper surface of the base 1. Mounting plates 4 are fixedly connected to both sides of the base 1. Several identical mounting holes 5 are opened on the upper surface of each mounting plate 4. By setting the mounting holes 5, the mounting plates 4 can be fixed to the reservoir bank or boat with the help of external bolts or positioning pins, thereby facilitating the fixing of the entire winch.

[0025] A rotating shell 304 is provided above the steel frame 301. The inner wall of the rotating shell 304 is rotatably connected to the outer surface of the first support 302. An extension frame 307 is slidably connected inside the rotating shell 304. Two handle supports 6 are fixedly connected to both sides of the base 1. A pull rod 7 is fixedly connected to the inner wall of each handle support 6. By setting the pull rod 7, a rotating base surface can be provided for the hand grip structure inside the handle support 6, thereby increasing the flexibility of the hand grip structure. At the same time, the handle support 6 and the pull rod 7 can work together with the above-mentioned hand grip structure to lift or move the entire winch.

[0026] A servo motor 308 is fixedly connected to the inner wall of the rotating housing 304. A threaded rod 309 is fixedly connected to the output end of the servo motor 308. The outer surface of the threaded rod 309 is threadedly connected to the inner wall of the extension frame 307. Each handle support 6 is equipped with a grip 8 inside. The inner wall of each grip 8 is rotatably connected to the outer surface of the pull rod 7. By setting the grip 8, it can rotate around the outer surface of the pull rod 7 inside the handle support 6, so that it is convenient to lift and move the entire winch when gripped by hand or hooked by an external lifting mechanism.

[0027] A second bracket 305 is fixedly connected to the front of the rotating shell 304. A rotating block 306 is rotatably connected to the outer surface of the second bracket 305. The telescopic end of the hydraulic push rod 303 is fixedly connected to the outer surface of the rotating block 306. Limiting sliders 10 are fixedly connected to both sides of the extension frame 307. The outer surface of each limiting slider 10 is slidably connected to the inside of the rotating shell 304. By setting the limiting sliders 10, the extension frame 307 can slide up and down inside the rotating shell 304, thereby increasing the stability of the extension frame 307 sliding up and down inside the rotating shell 304 and preventing the extension frame 307 from sliding out of the rotating shell 304.

[0028] A side guide wheel 311 is fixedly connected to the back of the rotating housing 304, and an inclined guide wheel 310 is fixedly connected to the upper surface of the extension frame 307. A coupling 9 is fixedly connected to the outer surface of the output end of the servo motor 308. The inner wall of the coupling 9 is fixedly connected to the outer surface of the threaded rod 309. By setting the coupling 9, the connection between the output end of the servo motor 308 and the threaded rod 309 can be strengthened, thereby increasing the rotational stability of the threaded rod 309.

[0029] The working principle of this utility model is as follows: In use, multiple external bolts or positioning pins are used in conjunction with the mounting holes 5 to fix the mounting plate 4 to the reservoir bank or a boat. Then, the container needed for retrieval is tightly wound around the outer end of the steel rope wound on the winch body 2. When it is necessary to retrieve blue-green algae near the winch body 2 in the reservoir, the rotating shell 304 is kept vertical or slightly tilted downwards. At this time, the hydraulic jack 303 needs to retract, and the rotating block 306 can rotate around the outer surface of the second support 305. Then, a portion of the steel rope wound on the winch body 2 is placed on the inclined guide wheel 310. The winch body 2 is started to release the steel rope and then reel it in. When it is necessary to retrieve blue-green algae far from the winch body 2 in the reservoir, the hydraulic jack 303 needs to be shortened first. With the assistance of the rotating block 306 rotating around the second support 305 and the rotating shell 304 rotating around the first support 302, the rotating shell 304 gradually moves downwards. The mechanism is flipped until the long side of the rotating shell 304 remains horizontal. Then, the servo motor 308 is energized to drive the threaded rod 309 to rotate, allowing the extension frame 307 to slide within the rotating shell 304. This controls the distance at which the inclined guide wheel 310 eventually moves away from the rotating shell 304. With the assistance of the side guide wheel 311, the inclined guide wheel 310 suspends the steel rope wound on the winch body 2 at different distances. After that, the winch body 2 is started to release and then reel in the steel rope. This allows the steel rope on the winch body 2 to easily scoop up algae from different distances after suspending the scooping container. The increase in the scooping area depends on the ratio of the suspension point adjustment mechanism 3 to the size of the winch body 2 during actual manufacturing. This ratio can be flexibly adjusted according to the specific application scenario. The design of the winch for the entire reservoir algae control project effectively solves the problem of inconvenient scooping of algae from different distances due to the lack of a steel rope suspension position adjustment structure.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
