[0006] As a further improvement of the technical scheme, an operating room is arranged on the upper end of the hull, and a door is arranged on one side of the operating room.
[0007] As a further improvement of the technical scheme, a power box is fixedly arranged on the upper end of the hull, a drive unit is installed in the inner cavity of the power box, a pulley frame is fixedly arranged on one side of the stern of the hull, a second rope is fixedly arranged at the output end of the drive unit, and one end of the second rope away from the drive unit passes through the upper end of the pulley frame and is hingedly connected to the upper end of the push wheel.
[0008] As a further improvement of the technical scheme, two groups of side floats are fixedly arranged on the bottom of the hull, and the two groups of side floats are symmetrically arranged on both sides of the bottom of the hull.
[0009] As a further improvement to this technical solution, push rods are fixedly installed on both outer walls of the hull, and one end of the push rod is hinged to the outer wall of the hull.
[0010] As a further improvement to this technical solution, the outer wall of the drive motor is provided with an oil inlet and a brake oil inlet, and both the oil inlet and the brake oil inlet are provided with sealing bolts.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. By setting up a rake head, the aquatic plants are cut and broken up. Then, an underwater pump is used to suck the broken aquatic plants into the water through a connecting pipe. The aquatic plants are then transported through the connecting pipe to a conveying pipe and then to a collection point on the hull for storage. In conjunction with the hull's navigation on the water, the water surface cleaning task is completed quickly, effectively maintaining the cleanliness and ecological balance of the water area.
[0013] 2. By setting up a support swing arm, the first rope is unwound by a hoisting winch, causing the first rope to pull the support swing arm to slowly rotate downwards. This allows the support swing arm to lower the rake head to the bottom of the water. The rake head loosens the silt at the bottom of the water and breaks up hard objects. Then, an underwater pump sucks the silt in through a connecting pipe and transports it to a delivery pipe. This process not only greatly improves the efficiency of silt removal but also effectively reduces the burden of manual cleaning and lowers operating costs. Attached Figure Description
