DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater cleaning suction cup for cleaning a tank or the like with water.

[0002]

[Prior art]

[0003] Conventionally, a suction cup has been used, for example, in an adsorption traveling cart that travels while adsorbing on a wall surface. In these, a rotating plate is attached to the tip of the air suction pipe, a skirt made of a flexible material is provided on the outer periphery of the rotating plate, and the inside of the skirt is made to have a negative pressure, and the rotating plate is tilted to prevent the air from being removed from the outer periphery of the rotating plate. One point on the outer circumference of the ring attached in the suction pipe direction is brought into contact with the wall, and the ring is advanced by the reaction force received from this contact point. These techniques are disclosed in Japanese Utility Model Laid-Open No. 1-68305 and Japanese Patent Laid-Open No. 3-104786 by the same applicant.

[0004] The water tank needs to be periodically cleaned because water deposits, dust, and the like enter therein. Conventionally, cleaning was performed with a manual brush or a rotating brush after draining water from the tank.

[0005]

In order to perform cleaning after draining water as described above, it is necessary to wait while draining water. This is because it is difficult to remove scales after draining the water and drying the inside of the tank. Further, when cleaning with a rotating brush or the like, it is suitable for work on the bottom plate of the tank or the like, but for work on the wall surface, a device for pressing the rotating brush against the wall surface is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an underwater cleaning suction cup which can be cleaned in water and can also clean a wall surface.

[0007]

In order to achieve the above object, a disk mounted on the end of a water suction pipe and rotated by a rotary driving body around the water supply pipe as a center of rotation is provided. And a rotating brush made of a flexible body provided with a rubbing body attached to the outer circumference of the ring in a skirt shape and having a flowing water channel in a direction opposite to the water supply pipe on the outer circumference.

A first rotating body which is attached to the end of the water absorption pipe and is rotated by the first rotary driving body about the water absorption pipe as a center of rotation, and has a ring formed in the outer periphery in the direction opposite to the water absorption pipe; A second rotating body rotatably mounted on the outer circumference of the first rotating body and rotating about the water absorption pipe by a second rotary driving body, and a skirt mounted on the outer circumference of the second rotating body in a direction opposite to the water absorbing pipe; And a rotating brush made of a flexible body provided with a scraping body having a flowing water channel.

[0009]

[Function] When water is absorbed from the water absorption pipe, water is sucked in from the bristle of the rotating brush or a rubbing part equivalent to this. A pressing force is generated on the brush. By this pressing force and the rotation of the rotating brush, water scale and dirt are removed and water is sucked out of the tank. Also, the pressing force by the negative pressure makes it possible to clean a vertical or overhanging wall surface by acting as a suction cup. When the rotating body is inclined so that the ring contacts the wall at one point, the vehicle can travel by this reaction force.

Further, the first rotating body and the second rotating body are respectively rotated by the first rotating body and the second rotating body, so that the first rotating body is rotated at a rotation speed suitable for traveling.
Since the second rotating body can rotate at a rotation speed suitable for cleaning,
The cleaning efficiency can be improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In the figure, a disk 2 is attached to a water absorption pipe end 1 via a bearing 9, and a ring 3 is attached to an outer periphery of the disk 2 on a lower surface of the disk 2 in the figure. A rotating brush 4, which is made of a skirt-shaped flexible material and is attached to the lower surface of the outer periphery of the outer periphery of the ring 3 and to which brush hairs or an equivalent scrubbing material is attached, is attached.

A rotary driving body 5 composed of a watertight electric motor or an air motor is fixed to the water-absorbing pipe end 1 by a spacer 10 and a nut 11 via a support plate 6. A pinion 7 is attached to a rotating shaft of the rotary driving body 5 and meshes with a gear 8 fixed to the disk 2.

FIG. 2 is a view showing an example of the rotating brush 4. As shown in FIG. The rotating brush 4 is made of a flexible material such as rubber or soft synthetic fiber. A brush in which hair is planted may be used at the contact portion with the tank wall, or a shape in which projections forming the water passage 19 as shown in the figure may be continuously arranged.

Next, the operation will be described. Put the device of this embodiment in a tank with water, install it in the area to be cleaned,
The pump is operated to start the water absorption operation, and the rotary drive 5 is rotated. When the disk 2 is tilted as shown in FIG. 1, it travels and can move in the cleaning area. By acting as a suction cup, not only the bottom plate of the tank but also the peripheral wall surface can be cleaned.

FIG. 3 shows a second embodiment, in which two devices shown in FIG. 1 are tilted inward each other as shown in FIG.
It is joined using the connecting member 20. By rotating the disks 2 in opposite directions, the runnability is improved and, of course, the cleaning range is doubled.

Next, a third embodiment will be described. In the present embodiment, a second disk 13 is provided on the outer periphery of the disk 2 and a rotary brassier 4 is mounted on the second disk 13 so that the ring 3 and the rotary brush 4 are rotated by independent rotary drivers 5 and 16, respectively.

FIG. 4 shows the configuration of the third embodiment. In this drawing, the same reference numerals as those in FIG. 1 represent members having the same functions. A mounting disk 12 is provided on the outer circumference of the disk 2, a second disk 13 is mounted via a second bearing 14, and the rotating brush 4 is mounted on the outer circumference of the second disk 13. Attach the second rotary drive 16 to the mounting disk 12
And the second pinion on the rotation axis of the second rotary drive 16
The second gear 18 attached to the second disk 13
Engage with.

In the case of this embodiment, the rotation of the ring 3 for determining traveling and the rotation of the rotating brush for determining cleaning can be made independent of each other. Cleaning efficiency is improved.

[0019]

As is clear from the above description, the present invention enables not only cleaning in water but also cleaning on a wall surface by suction action by combining a suction cup and a rotating brush.
