Description

Technical Field

[0001] The utility model relates to the technical field of fishway cleaning, in particular to a fishway cleaning machine. Background Art

[0002] The construction of hydropower and water conservancy projects can provide humanity with relatively clean energy. However, in practice, their impact on the ecological environment is significant, particularly on local river ecosystems. Dam construction raises water levels, blocking rivers and making it difficult for fish to migrate. This can be particularly devastating for spawning fish. Therefore, a more mature technology is to construct fishways within hydropower and water conservancy projects to facilitate fish migration. As an ecological restoration measure to mitigate the impact of hydropower and water conservancy projects on fish, fishways are gaining increasing attention from all sectors of society and environmental protection authorities.

[0003] A large amount of sediment will accumulate on the surface of the fishway during long-term use, and the fishway plate needs to be disassembled for cleaning. The existing cleaning is generally done manually, which is labor-intensive and inefficient. Therefore, a fishway cleaning machine is needed to improve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a fine sand recovery device for cleaning fishways of different sizes and shapes, and to solve the problems of high labor intensity and low efficiency of manual cleaning in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a fishway cleaning machine, comprising a cleaning machine housing, a mounting seat fixedly provided inside the cleaning machine housing, and an auxiliary roller group fixedly provided on the upper end of the mounting seat;

[0009] In a preferred embodiment, a second hydraulic cylinder is hingedly connected to the side surface of the second mounting plate, the cylinder body of the second hydraulic cylinder is connected to the second mounting plate via a hinge seat, the push rod end of the second hydraulic cylinder is hinged to one end of the side roller group base, and the other end of the side roller group base is connected to the second mounting plate via a hinge seat;

[0010] The second hydraulic cylinder is used to adjust the inclination of the side roller group.

[0011] In a preferred solution, the spray rod is arranged in an arc shape, a plurality of spray ports are provided on the surface of the spray rod, and the spray rod is connected to the high-pressure water pump through a hose.

[0012] In a preferred solution, the active drive roller group is composed of a plurality of rotating roller shafts connected by a chain and a motor driving the rotating roller shafts.

[0037] When the fishway cleaning machine disclosed in this application is used for fishway cleaning operations:

[0038] 1. Preparation stage: Place the fishway plate upside down on the conveying roller group 19 on both sides of the cleaning machine shell, ensure that the fishway plate is in the correct position, and prepare to be sent into the cleaning machine.

[0039] 2. Fixing and transporting: The fishway plate is sent into the interior of the cleaning machine housing 18 and placed on the upper end of the auxiliary roller group 4. The first hydraulic cylinder 1 is started to drive the active drive roller group 3 to descend, pressing it against the surface of the fishway plate to complete the fixation.
