Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underwater surface cleaning device used for underwater removal of deposits such as seaweed and shellfish attached to underwater surfaces of ships and buildings.

Since seaweed, shellfish, etc. adhere to underwater surfaces such as ships, it is necessary to remove these deposits as appropriate. Various cleaning devices have been proposed to remove such deposits. One of them is an underwater surface cleaning device that has a motor and a rotating brush and cleans the underwater surface underwater. However, the underwater surface cleaning devices that have been proposed so far have not been put into practical use because they are troublesome to handle and have poor workability.

The present invention provides an underwater surface cleaning device which is intended to be easy to handle and improve workability.

The underwater surface cleaning device according to the present invention includes an impeller/motor housing M device located in the center of a cylindrical outer shell that forms a passage from an inlet to an outlet, and a housing M for an impeller motor located in the passage. An impeller is provided to inject water from the inlet to the outlet, and a rotating brush is provided on the inlet side of the passage coaxially with the rotation axis of the impeller, and an outer shell is provided on the outlet side of the passage. A water flow regulating plate inclined with respect to the axis of the outer shell is provided between the inner wall of the housing and the outer wall of the housing, and the rotating brush is rotated by the rotation of the impeller, and at the same time, the jet flow generated by the rotation of the impeller causes the water flow adjusting plate to rotate. is pressed against the surface below the water surface.

The present invention will be described in detail below based on embodiments shown in the drawings.

The underwater surface cleaning device 1 according to the present invention is provided with a cylindrical outer shell 3 that forms a passage 2 from an inlet to an outlet in the center. Two of these outer M3s are arranged side by side in a draft tube 5 provided inside a buoyant body 4 which is the body of the cleaning device 1, and are movable in two directions of the passage. The two outer shells 3 are connected by a connecting body 6. The draft tube 5 is provided with a hydraulic cylinder 7, a cylinder rod 8 of the hydraulic cylinder 7 is connected to the connecting body 6, and the two outer shells 3 are moved by the hydraulic cylinder 7. An impeller/motor housing 9 is arranged in the center of each of the two outer shells 3. Inside the housing 9 is a hydraulic motor 1 having a rotation axis lO.
1 is fixed, and a rotation base 12 is fixed to the rotating shaft 10, and this rotation base 12 is provided with an impeller 13 located in the passage z and injecting water from the inlet to the outlet. . Further, a rotating brush 1 for cleaning is provided via a rotating base 12 on the same axis as the rotating shaft 10 of the impeller 13.
4 is located on the entrance side of the passage 2 and is detachably attached. Further, on the outlet side of the passage z, a water flow adjustment plate 15 is provided between the inner wall of the outer shell 3 and the outer wall of the housing 9, and is inclined with respect to the M line of the outer shell 3. The housings 9 are connected to each other by a water flow regulating plate 15. The water flow adjusting plate 15 converts the jet flow generated from the inlet of the passage 2 toward the outlet by the rotation of the impeller 13 from a vortex to a rectified flow, and at the same time serves to reinforce the outer shell 3.

Wheels 1 are mounted on the surface below the water surface of the cleaning device 1, that is, on the side that comes into contact with the surface to be cleaned.
6 are arranged at four locations, each of which is driven by a hydraulic motor (not shown), and the cleaning device l
is moved over the surface to be cleaned by driving the wheels 16.

The hydraulic motor 11 that rotates the impeller 13 and the rotating brush 14, the hydraulic motor that drives the hydraulic cylinder 7, and the wheels 16 are supplied with oil through cables from the ground or from a power transmission ship. And hydraulic motor 11
The hydraulic cylinder 7 and the hydraulic motor that drives the vehicle m16 are controlled by operating operating levers 18, 19, and 20 on the operating panel 17.

Furthermore, a one-rotation brush 1 is installed at the opening of the draft tube 5.
A mesh bag (
(not shown).

In such a configuration, when the impeller 13 and the rotating brush 14 are rotated by the hydraulic motor 11 with the rotating brush 14 facing the surface to be cleaned, the impeller 13 sucks water into the passage 2 from the inlet and injects it from the outlet. However, due to this reaction, the cleaning device 1 is pressed against the surface to be cleaned. At the same time, the rotation of the rotating brush 14 removes deposits from the surface to be cleaned. Here, the jet flow passing through the passage 2 due to the rotation of the impeller 13 becomes a water flow rectified by the water flow regulating plate 15, so that the cleaning device 1 is stable and the pressing force against the surface to be cleaned is strong. The rotary brush 14 is highly effective in removing deposits, and there is no need for a wiper to press the cleaning device 1 against the surface to be cleaned, making it easy to handle and have good workability.

As described above, the underwater cleaning device according to the present invention is lightweight and compact, and is easy to handle, has good workability, and can improve cleaning work efficiency.
