Description

Technical Field

[0001] This invention relates to the field of water surface garbage cleaning equipment, and in particular to a garbage cleaning vessel used in front of a hydropower station dam. Background Technology

[0002] Cleaning up debris from the water surface in front of a hydropower station dam is a critical task, especially during the rainy season. If floating debris accumulates upstream in front of the dam and is not cleaned up promptly, it can clog the turbine intakes or the debris barriers in front of the dam. This seriously threatens the safety of the debris barriers and turbine equipment, can cause blockages in the debris barriers, reduce turbine output, or even force the turbines to shut down, resulting in significant energy loss.

[0003] Currently, in the existing dam operating environment, floating debris frequently exists in the reservoir's upstream water level area. If this floating debris intrudes into the power generation system, it could potentially trigger accidents that are difficult to handle. The current common practice for debris removal at hydropower stations is to use traditional manual dredging methods. Specifically, this requires specialized operators to control the dredging vessel, along with two to three workers on the vessel's side to carry out the dredging operations. This traditional method not only consumes significant human and material resources but also harbors substantial high-risk factors. Considering that the reservoir's upstream water level can typically reach tens or even hundreds of meters, in such circumstances, if a worker accidentally falls into the water, the rescue operation will face an extremely challenging situation and be incredibly difficult.

[0004] Traditional salvage vessels typically involve operators maneuvering the vessel to the garbage collection point, where a grid-type conveyor belt carries the garbage to a higher elevation before transferring it back to the salvage vessel. However, since most floating garbage in the water is quite small, such as dead leaves, driftwood, aquatic plants, and phytoplankton, these tiny debris easily become entangled in the conveyor belt's grid. As the conveyor belt continues to operate, the amount of garbage attached to it increases. If not cleaned promptly, this can damage the machine. Furthermore, after a period of operation, significant manpower and time are required for cleaning, necessitating improvements. Summary of the Invention

When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1, referring to Figures 1-6 The first embodiment of the present invention provides a garbage cleaning vessel for front of a hydropower station dam. This device includes a main unit 100, including a hull 101, two gathering plates 102 disposed on the hull 101, and a power assembly 103 disposed on the hull 101; and a cleaning unit 200, including a screw conveyor assembly 201 disposed on the hull 101, a garbage collection assembly 202 disposed on the hull 101 and connected to the screw conveyor assembly 201, an automatic sealing assembly 203 disposed on the garbage collection assembly 202, and an inspection assembly 204 disposed on the hull 101.

[0034] Two gathering plates 102 are fixedly connected to the two sides of the bow of the hull 101, and the two gathering plates 102 are arranged opposite each other and tilted at 45 degrees, so as to present a change from wide to narrow, so as to gather the garbage in the water when the hull 101 moves, making it more convenient for the cleaning unit 200 to carry out cleaning work.

[0035] In use, the movement of the hull 101 can be controlled by the power component 103. The spiral conveyor component 201 can transport and clean the garbage in the water gathered by the gathering plate 102 in a spiral manner. The garbage collection component 202 can collect the garbage transported by the spiral conveyor component. The automatic sealing component 203 can automatically seal the garbage collection component 202 when it is full and stop the cleaning operation. The inspection component 204 can avoid manual operation of the hull 101, realize unmanned and automated cleaning of garbage in the water, enhance the automation of the device, and avoid the safety hazards of manual operation of the hull 101 to retrieve garbage.

[0036] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the power assembly 103 includes an engine 103a mounted on the hull 101 and a propeller 103b mounted on the engine 103a. The movement of the hull 101 can be controlled by rotating the propeller 103b driven by the engine 103a.

[0037] Furthermore, the screw conveyor assembly 201 includes two oblique through holes 201a disposed on the hull 101, an inclined conveying pipe 201b disposed inside the oblique through holes 201a, and a motor 201c disposed on the inclined conveying pipe 201b; wherein, the two inclined conveying pipes 201b are respectively fixedly connected to the inside of the two oblique through holes 201a, and the two oblique through holes 201a are opened at the bow of the hull 101. The inclined conveying pipe 201b is inclined, with half of its bottom end submerged in the water and the other half on the water surface, thus it can not only clean up garbage floating on the water surface, but also clean up garbage in the water, making it highly applicable. The motor 201c is fixedly connected to the top of the inclined conveying pipe 201b.

[0038] Furthermore, the screw conveyor assembly 201 includes a drive shaft 201d disposed in the inclined conveying pipe 201b and connected to the motor 201c, a screw blade 201e disposed on the drive shaft 201d, and a connecting frame 201f disposed on the inclined conveying pipe 201b and connected to the drive shaft 201d; wherein, the drive shaft 201d is fixedly connected to the output end of the motor 201c, the screw blade 201e is fixedly connected to the drive shaft 201d, and the connecting frame 201f is fixedly connected to the bottom end of the inclined conveying pipe 201b, and the bottom end of the drive shaft 201d is rotatably connected to the connecting frame 201f through a bearing; the arrangement of the inclined conveying pipe 201b and the screw blade 201e enables timely separation of water and garbage during the process of conveying floating garbage from a low place to a high place, which facilitates subsequent garbage transportation and processing, and can reduce the damage to the device caused by small debris entanglement, making it highly practical.

[0039] Furthermore, a guide pipe 201b-1 is provided on the inclined conveying pipe 201b, and a protruding plate 201b-2 is provided between the two connecting frames 201f. The two inclined conveying pipes 201b are located between the two gathering plates 102. The guide pipe 201b-1 is connected to the highest point of the bottom of the outer surface of the inclined conveying pipe 201b, so that when the waste is conveyed from the low to the high position, it can be discharged through the guide pipe 201b-1. The protruding plate 201b-2 is fixedly connected between the two inclined conveying pipes 201b. Since there is a certain gap between the two inclined conveying pipes 201b, the setting of the protruding plate 201b-2 facilitates the entry of waste into the two inclined conveying pipes 201b.

[0040] Furthermore, the waste collection component 202 includes two chutes 202a disposed on the hull 101, a collection box 202b disposed on the hull 101 and connected to the two chutes 202a, and a handle 202c disposed on the collection box 202b. The chutes 202a are located on the hull 101, and the bottom of the collection box 202b is provided with protrusions that are adapted to the chutes 202a, so that the collection box 202b can slide in the chutes 202a. After the collection box 202b is full of waste, the waste can be emptied by sliding the collection box 202b away from the guide pipe 201b-1. The handle 202c facilitates the movement of the collection box 202b by the staff.

[0041] Furthermore, the automatic sealing assembly 203 includes a cover 203a disposed above the collection box 202b, an inlet 203b disposed on the cover 203a and communicating with the guide pipe 201b-1, a cavity 203c disposed inside the cover 203a, and two sealing plates 203d disposed inside the cavity 203c; wherein, the cover 203a is fitted to the collection box 202b, the inlet 203b is opened at the top of the cover 203a, and there are two inlets 203b, the positions of the two inlets 203b are respectively Corresponding to the positions of the two guide pipes 201b-1, the cavity 203c is opened inside the cover 203a, and the cavity 203c is connected to the feed inlet 203b. The two sealing plates 203d are slidably connected inside the cavity 203c. When the two sealing plates 203d are fully open, the two feed inlets 203b are fully exposed, which facilitates the entry of garbage. Conversely, when the two sealing plates 203d are fully closed, they close the feed inlets 203b and stop the operation of the motor 201c, that is, stop the cleaning work.

[0042] Furthermore, the automatic sealing assembly 203 also includes a connecting plate 203e disposed on the box cover 203a, two storage slots 203f disposed on the connecting plate 203e, a telescopic cylinder 203g disposed in the storage slots 203f, and a connecting block 203h disposed on the telescopic cylinder 203g and connected to the sealing plate 203d. A sealing sensor 203i is disposed on the inner wall of the collection box 202b. The connecting plate 203e is located in the middle of the top of the box cover 203a, and is positioned between the two guide pipes 201b-1. The material troughs 203f are respectively opened on both sides of the connecting plate 203e. One end of the telescopic cylinder 203g is fixedly connected to the inside of the material trough 203f, and the other end of the telescopic cylinder 203g is fixedly connected to one side of the top of the sealing plate 203d through the connecting block 203h. The sealing sensor 203i is located on the top of the inner wall of the collection box 202b. When the garbage inside the collection box 202b is full, the sealing sensor sends a signal, the system receives feedback, and can then start the telescopic cylinder 203g to drive the sealing plate 203d to close the feed port 203b, and at the same time stop the cleaning work.

[0043] Furthermore, the lid 203a is provided with two fixing plates 203a-1 connected to the hull 101, and the collection box 202b is provided with two positioning plates 203a-2 located below the fixing plates 203a-1. The positioning plates 203a-2 are provided with positioning holes 203a-3, and the fixing plates 203a-1 are provided with screws 203a-4 connected to the positioning holes 203a-3. The lid 203a is fixedly connected to the hull 101 via the fixing plates 203a-1. On the top of the collection box 202b, two positioning plates 203a-2 are fixedly connected to the top of both sides of the collection box 202b, and the positioning plates 203a-2 are located below the fixing plate 203a-1. The positioning holes 203a-3 are opened on the positioning plates 203a-2. The fixing plate 203a-1 is provided with threaded holes that are threadedly connected to the screw 203a-4, and the position of the threaded holes corresponds downward to the position of the positioning holes 203a-3, so that the screw 203a-4 can position the collection box 202b.

[0044] In use, by starting and controlling the engine 103a, the propeller 103b is driven to rotate, thereby controlling the movement of the hull 101. When cleaning up garbage, the inspection component 204 identifies the garbage in the water and plans the best route to move the hull 101 to the garbage. During the movement of the hull 101, the two gathering plates 102 will gather the garbage on the route. At the same time, the electric motor 201c drives the drive shaft 201d and the spiral blades 201e to spirally transport the gathered garbage to the highest point of the inclined conveying pipe 201b. After passing through the guide pipe 201b-1 and the inlet 203b, it enters the collection box 202b.

[0045] As garbage continues to enter, when the sealing sensor 203i detects that the inside of the collection bin 202b is full, the system receives feedback and activates the telescopic cylinder 203g to move the two sealing plates 203d in opposite directions to completely close the inlet 203b. At the same time, the cleaning work stops, and the hull 101 is brought ashore. Workers can then pull the collection bin 202b out from under the lid 203a using the handle 202c, allowing for centralized processing of the garbage inside the collection bin 202b.

[0046] The remaining structure is the same as that in Example 1.

[0047] Example 3, referring to Figure 1 This is the third embodiment of the present invention, which differs from the second embodiment in that: the inspection component 204 includes a support plate 204a disposed on the hull 101, and an inspection camera 204b disposed on the support plate 204a; wherein, the support plate 204a is fixedly connected to the hull 101, the inspection camera 204b is disposed at the highest point on the support plate 204a, and the inspection camera 204b can rotate at multiple angles to inspect the water surface.

[0048] In operation, the inspection component 204 acts as the eyes of the entire device, playing a crucial guiding role in the garbage cleanup operation. Under normal operating conditions, if the garbage on the water surface in front of the dam is scattered, the cleanup device can adopt a zigzag route to ensure that the entire area is cleaned without omission. When the amount of floating garbage on the water surface is small or its distribution is relatively concentrated, the inspection camera 204b can be fully utilized to quickly inspect the river surface for garbage. Then, the most reasonable retrieval route is planned and fed back to the device's control system, improving work efficiency.

[0049] The remaining structure is the same as that in Example 2.
