Description

Technical Field

[0001] This utility model relates to the technical field of water surface cleaning equipment, and more specifically, to a cleaning device for dispersed floating objects on the water surface. Background Technology

[0002] During the flood season, the water surface at the intake of hydropower stations experiences a significant amount of floating debris. When the generating units operate unevenly and the intake flow is turbulent, some of the floating debris cannot be collected and appears disorderly distributed across the wide water surface in front of the dam. This floating debris not only affects the aesthetics and ecological balance of the water area but can also adversely impact water conservancy facilities and navigation. Currently, common floating debris removal devices have several shortcomings. For example, some devices have limited cleaning range, making it difficult to effectively collect floating debris scattered over large areas; some devices have complex structures, are inconvenient to operate, and have high maintenance costs; and some devices have difficulties unloading the collected debris, affecting work efficiency. Furthermore, traditional cleaning devices are poorly adaptable to different water flow speeds and wave conditions, easily leading to poor cleaning results. Therefore, developing a new type of cleaning device is of significant practical importance for more efficient and convenient removal of scattered floating debris and for protecting the environment and water resources. Utility Model Content

[0003] Based on the above-mentioned technical problems, this utility model proposes a cleaning device for dispersed floating objects on the water surface.

[0004] A device for cleaning floating debris on water surfaces includes: a hull, a fixed frame, a movable frame, and a sludge-collecting mesh. The fixed frame is detachably installed at the end of the hull. The movable frame is parallel to the fixed frame and positioned directly below it. Each end of the fixed frame and the movable frame has an openable and closable square frame composed of flexible strips. The opening of the sludge-collecting mesh is fixed to the square frame, and the rear end of the mesh is tied and sealed. The hull is also equipped with a lifting device, the lifting cable of which is connected to the movable frame. The fixed frame and the movable frame are equipped with vertically aligned lifting hooks.

[0005] Preferably, the movable frame is provided with counterweights at both ends, and the counterweights are located below the mesh opening of the dirt collection wire mesh.

[0006] Preferably, multiple lifting devices are provided and arranged symmetrically around the center of the movable frame.

[0007] Preferably, the lifting device consists of a winch, a vertical frame, and a pulley.

[0010] Figure 2 The diagram shows the operational status of this utility model;

[0011] Figure 3 The diagram shows the structure of the fixed frame and the movable frame working together. Detailed Implementation

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0013] like Figures 1-3 The device shown is a cleaning device for dispersing floating objects on the water surface. The device includes a hull 1, a fixed frame 2, a movable frame 3, and a filament collection mesh 4.

[0014] The fixed frame 2 is detachably installed at the end of the hull 1 to provide a stable support structure for the cleaning device. The movable frame 3 is parallel to the fixed frame 2 and is set directly below the fixed frame 2. Each end of the fixed frame 2 and the movable frame 3 is provided with an openable square frame 6 composed of flexible strips 5. The two square frames 6 are symmetrically arranged on the left and right. The mesh opening of the sludge collection mesh 4 is fixed on the square frame 6. The rear end of the sludge collection mesh 4 is tied and sealed. This design can effectively collect floating objects scattered on the water surface, and the openable square frame 6 makes it easy to adjust the collection range and seal the opening.

[0015] The hull 1 is also equipped with a lifting device. The lifting cable 13 of the lifting device is connected to the movable frame 3 and is used to control the lifting and lowering of the movable frame 3. The lifting device consists of a winch 7, a vertical frame 8, and a pulley 9. The winch 7 is fixed to the hull 1. The lower end of the vertical frame 8 is hinged to the hull 1. The pulley 9 is rotatably installed on the top of the vertical frame 8. A stabilizing frame 10 is also provided on the rear side of the vertical frame 8. The two ends of the stabilizing frame 10 are respectively connected to the upper part of the hull 1 and the vertical frame 8. The lifting cable 13 is led out from the winch 7, passes around the upper part of the pulley 9, and is connected to the movable frame 3 to achieve precise control of the movable frame 3.

[0016] Multiple lifting devices are typically installed and symmetrically arranged around the center of the movable frame 3 to ensure the stability and reliability of the lifting of the movable frame 3.

[0017] The fixed frame 2 is generally set at the upper part of the front end of the hull 1, and the hull 1 is located in the middle of the fixed frame 2. The movable frame 3 is located below the fixed frame 2, and the movable frame 3 can be moved upward in the vertical direction by the lifting device. In order to ensure that the movable frame 3 will not tilt laterally, a vertical sliding rod 11 can be set on each side of the central axis of the fixed frame 2. The movable frame 3 is locked on the sliding rod 11 and slides up and down along the sliding rod 11. This ensures that the movable frame 3 will not deviate, thereby avoiding the deformation of the frame 6.

[0018] The fixed frame 2 and the movable frame 3 are equipped with lifting hooks 12 facing each other vertically. The hook at the lower end of the sling 13 in the lifting device is attached to the lifting hook 12 on the movable frame 3. After the sling 13 is released from the fixing of the lifting hook 12 and the fixed frame 2 is released from the fixing of the ship hull 1, the hook of the shore gantry crane will simultaneously hook the two lifting hooks 12 to lift it up, which facilitates the transfer of the whole device.

[0019] The working process of this device is as follows:

[0020] When it is necessary to clean up scattered floating debris on the water surface, the movable frame 3 is lowered to a certain depth below the water surface by its own weight using a lifting device. After being lowered, the openings of the collection mesh 4 open. Two collection meshes 4 are symmetrically arranged on both sides of the hull 1. After the openings are open, the rear of the collection mesh 4 is tied and lowered into the water. The collection mesh 4 can be tied according to the actual needs of the site to achieve the required volume. As the hull 1 moves, the open collection meshes 4 can collect the scattered debris floating on the water surface. Once the collection mesh 4 is full, the lifting device will lift the movable frame 3 and finally make contact with the fixed frame 2 to close the mesh opening. Then, the full collection mesh 4 will be transported to the designated location by boat. The collection mesh 4 can be lifted and transported to the designated location by hooking the fixed frame 2 and the movable frame 3 with the lifting hooks 12 of the vehicle on the dam surface or waterside, such as truck cranes or gantry cranes. The wastewater can then be discharged to the transfer equipment or dam surface by opening the wastewater discharge locking device at the bottom of the flexible wastewater collection hopper.

[0021] As a further improvement, the movable frame 3 is equipped with counterweights 14 at both ends. The counterweights 14 are located below the mesh opening of the filth collection mesh 4, which helps the filth collection mesh 4 maintain a stable position and shape in the water and improves collection efficiency.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
