Description

Technical Field

[0001] The utility model relates to the field of underwater mechanical equipment, in particular to a boat washing device. Background Art

[0002] The underwater hull is often attached with marine organisms such as oyster barnacles, which increases the resistance to navigation and causes additional fuel consumption. The hull needs to be cleaned regularly. The traditional method requires the ship to be docked for cleaning, which has high maintenance costs. After searching, Chinese patent CN 108500997 A discloses a curved wall-climbing robot for surface cleaning, including a front-wheel drive mechanism, a rear-wheel drive mechanism, a posture adjustment mechanism and a cleaning and rust removal mechanism. The characteristics are as follows: the front-wheel drive mechanism and the rear-wheel drive mechanism have the same structure, the drive motor and the motor mounting plate in the drive mechanism are mounted on the drive chassis through the side support plate, the drive motor drives the differential, sprocket, gear train and universal wheel to rotate through the chain; the permanent magnet is suspended under the drive chassis, and the drive chassis is fixed to the chassis wheel axle so that the robot is adsorbed on the working wall; the differential can adjust the speed of the left and right wheels in the gear train during steering; the steering motor in the posture adjustment mechanism drives the front wheel rotating claw and the rear wheel connecting claw to rotate through the articulated connection, thereby driving the connecting rod to move, so that the front wheel drive mechanism can be fixed to the working wall; The driving mechanism and the rear wheel driving mechanism turn in opposite directions; the guide air driver and the cylinder in the cleaning and rust removal mechanism are fixed to the side of the crossbeam through a mounting frame, and the cleaning disc can swing by controlling its posture. The crossbeam spans between the front wheel driving mechanism and the rear wheel driving mechanism; the soft rubber pad is fixed to the lower side of the cleaning disc and can press the working wall surface; the rotator nozzle is fixed to the center of the upper surface of the cleaning disc, connected to the high-pressure water pipe, and sprays high-pressure water outward through the spray rod; it also includes a damper, which is connected to the front wheel driving chassis and the crossbeam and can be compressed or stretched; the front wheel chassis is hinged to the damper so that the permanent magnet maintains a posture tangent to the curved surface; the damping sleeve is sleeved on the outside of the damper, connecting the front wheel rotating claw and the driving chassis, and can transmit steering torque. The shortcomings of the above patent are:

[0003] First, in the above-mentioned patent, a cleaning disc is set in the middle of the driving chassis, and a spray rod is set in the cleaning disc, and spraying is carried out through the spray rod. Because the cleaning disc is set in the middle of the driving chassis and the spray rod is set in the cleaning disc, the spray range of the spray rod is small, resulting in a small cleaning range. When a large range of cleaning is required, the entire robot needs to be moved repeatedly, which has high energy consumption and high cost of use; second, the above-mentioned patent provides a front-wheel drive mechanism and a rear-wheel drive mechanism, and the drive motor drives the differential, sprocket, gear train, and universal wheel to rotate through a chain. The structure is complex, there are many components, the cost of use is high, and the operation is inconvenient; third, in the above-mentioned patent, the four walking wheels can only turn at the same time, and a single walking wheel cannot turn freely without the other walking wheels, which makes the operation of the walking wheels very inconvenient and cannot be adjusted according to the environment in which each walking wheel is located. When there is an obstacle such as water plants, oysters, etc. in front of a walking wheel, the position of the entire driving disc needs to be adjusted to avoid or bypass the water plants, which greatly increases energy waste and reduces cleaning efficiency.
