Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cleaning device used for underwater removal of deposits such as seaweed and shellfish adhering to underwater surfaces of ships and buildings.

[Prior art] Conventionally, as a cleaning device for an object to be cleaned underwater,
Some devices include a rotating brush that is submerged in water and a pump that generates a water flow from the front side of the rotating brush to the back side of the rotating brush. The rotary brush is driven and the rotary brush is rotated to remove deposits attached to the object to be cleaned.

When using such a cleaning device, it is necessary to carry the cleaning device to the object to be cleaned and direct the front side of the rotating brush of the cleaning device toward the object to be cleaned, but this work requires a diver towing the cleaning device. , and the front side of the rotating brush is directed toward the object to be cleaned.

[Problems to be solved by the invention] As mentioned above, in the case of the conventional cleaning device, the cleaning device must be towed by a diver to the object to be cleaned, and the rotation of the cleaning device is The front side of the brush must face the object to be cleaned,
Such work has become extremely troublesome.

In particular, when the front side of the rotating brush of the cleaning device is directed toward the object to be cleaned, the surface of the object to be cleaned is vertical or parallel to the surface of the cleaning device, since the cleaning device is generally structured to have a buoyant force that makes it horizontal in the water. If the cleaning device is in a vertical or nearly vertical position, the cleaning device must be operated so that the front side of its rotating brush faces the surface of the object to be cleaned; The problem is that the balance in the water becomes unstable due to the buoyancy force that tries to return to the horizontal level, making the operation extremely troublesome and difficult.

This invention solves the above-mentioned problems and further provides a cleaning device for an object to be cleaned underwater, which aims to bring the front side of the rotating brush of the cleaning device into pressure contact with the object to be cleaned.

[Means for solving the problem] In order to achieve the above object, this invention has a rotating brush and a steering wheel that can come into contact with the object to be cleaned on the side facing the object to be cleaned in the water. In a cleaning device that cleans by moving along a surface, propeller blades for propulsion are provided at the front and rear of the main body of the cleaning device, respectively, so that they can rotate forward and backward, and the propeller blades installed at the front can be rotated forward or backward. A front propeller blade angle adjustment section that adjusts in the left-right or front-rear and left-right directions, and a rear propeller blade angle adjustment section that adjusts the direction of the propeller blades provided at the rear in the front-rear direction are provided.

[Operation] When the cleaning device is floated horizontally in water and the propeller blades installed at the front and rear of the cleaning device body are adjusted and driven in the respective directions of travel, the cleaning device will move in the same direction while maintaining a horizontal state. Then, by changing the propeller blades installed at the front to the left or right with respect to the direction of travel, it changes direction and moves in the same direction. Furthermore, when each of the propeller blades is driven in a direction perpendicular to the cleaning device, the cleaning device sinks into the water while maintaining a horizontal state. Further, in the same state, when either the front or rear propeller blades are driven, the propeller blades dive into the water, and the cleaning device changes its attitude in the vertical direction. Furthermore, in this state, when the front side of the rotating brush of the cleaning device is brought into contact with the object to be cleaned and each propeller blade is driven, the cleaning device is brought into pressure contact with the object to be cleaned and maintains this state.
