Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter cleaning apparatus for a sedimentation basin in a sewage treatment plant, and more particularly to an apparatus for easily and surely cleaning an overflow gutter in a sedimentation basin without imposing a large burden on an operator. About.

[0002]

2. Description of the Related Art Usually, in a sewage treatment plant, as shown in FIG. 11, a large number of sedimentation basins P... Are provided in a grid pattern, and overflow from troughs (rectifying plates) T. The treated water is drained from the settling ponds P, the overflow gutters R1, R2 between the P to the river or the like. By the way, in such sedimentation ponds, algae are generated in the overflow gutter and it is easy to breed. It is not environmentally friendly.

[0003] Therefore, the operator has been trying to clean the overflow gutter manually by rubbing the side wall surface and the bottom surface of the overflow gutter with a deck brush, but it takes a long time to clean the overflow gutter. Was a heavy burden.

On the other hand, there has been proposed a method in which a brush body and a driving source are mounted on a robot, and the side wall surface and the bottom surface of the overflow gutter are cleaned by rotating the brush body while running the robot along the overflow gutter. (For example, see JP-A-5-21)
2215, JP-A-9-323006, etc.).

[0005]

However, in the conventional cleaning robot, a vertical gutter R1 connected to a river or the like and a horizontal gutter R2 crossing the vertical gutter R1 in a cross type overflow gutter as shown in FIG. In reality, it is difficult to clean both the downspout R1 and the downspout R2 with one type of robot having different depths and widths.

Further, in the downspout R1, the downspout becomes deeper in the flow direction of the treated water, so that when the side wall surface is to be cleaned, if the brush body is set short, the cleaning can be left unfinished, but long. As a result, it becomes difficult to clean, and as a result, a complicated mechanism for adjusting the length of the brush body on the side wall surface is required, and the cost becomes extremely high. In fact, the fact is that workers are manually cleaning.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to make it possible to clean an overflow gutter to every corner without increasing costs and without putting a heavy burden on an operator.

[0008]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the cleaning work is not completely automated, but the worker rotates the brush body by a driving source while rotating the brush body. Should be pushed by hand to clean it.Also, instead of cleaning the side and bottom of the overflow gutter at the same time, clean the side of the overflow gutter, Have come to the point that it is only necessary to separately clean them.

Therefore, an apparatus for cleaning the overflow gutter of a sedimentation basin according to the present invention is a cleaning device for cleaning the side wall of the overflow gutter of the sedimentation basin in a sewage treatment plant, and has a handle body that can be gripped by an operator. Then, a bogie that is moved along the top end surface of the overflow gutter side wall by pushing and pulling of the overflow gutter is spaced apart from the bogie to be cleaned by a distance larger than the width of the side wall of the overflow gutter to be cleaned. Each of the bogies extends downward from both sides thereof and is rotatably supported about a vertical axis. The bogie is tilted with respect to the moving direction so that the bogies are in sliding contact with both sides of the overflow gutter side wall. And a pair of side cleaning brushes for cleaning the both side surfaces, and driving means mounted on the carriage and driving the side cleaning brushes to rotate.

One of the features of the present invention is that the two side cleaning brushes are provided at a predetermined interval in the width direction of the overflow gutter, the carriage is inclined with respect to the moving direction, and the rotating side cleaning brushes are used. The point is that both sides of the overflow gutter are cleaned. Accordingly, the burden on the worker is lighter than when the overflow gutter is rubbed using the deck brush, and the burden on the worker is reduced even if the worker pushes and pulls the carriage.

Another feature of the present invention is that the rotating side cleaning brush body is brought into sliding contact with both sides of the overflow gutter by sandwiching the bogie with respect to the moving direction. It is in. As a result, even when the width of the side wall is different, such as the vertical gutter and the horizontal gutter of the cross-type overflow gutter, the inclination angle of the bogie can be easily changed without changing the interval between the side cleaning brush bodies. it can. As a result, there is no need to provide a complicated mechanism for adjusting the distance between the side cleaning brush bodies, not only does the cost of the apparatus increase, but also the weight of the apparatus can be reduced. Can push and pull the trolley lightly.

Further, since the bogie travels along the top end surface of the overflow gutter, it is preferable to use this to clean the top end surface. Therefore, a top end cleaning brush body rotatably supported by a support shaft extending downward from the bottom of the cart is further provided,
It is preferable that the top end cleaning brush body is rotated by the driving means to clean the side wall top end surface.

When the truck is inclined with respect to the traveling direction, the operator may operate the handle to incline the truck. However, if the rotation direction of the side cleaning brush is properly set, the cleaning brush can be tilted. The bogie can be automatically tilted by the turning force of. That is, when the pair of side cleaning brush bodies are rotated in the same direction, the pair of side cleaning brush bodies can be pressed against the side wall side surface by the mutual rotational force.

The cart is caused to travel on an inclination as described above, but the handle of the cart is raised and lowered so that the pushing and pulling force of the worker is efficiently transmitted to the cart and the worker can easily and smoothly push and pull. Preferably, the angle of the direction around the axis can be adjusted.

The wheels of the truck may be fixedly mounted. However, in consideration of running on the top end of the side wall of the overflow gutter, the truck is provided with a wheel receiver having at least a pair of front and rear wheels. It is preferable to be able to freely rotate about the axis of the wheel so that the angle of the wheel receiver according to the width of the top end during traveling or the like can be appropriately changed. On the other hand, it is troublesome to manually change the angle of the wheel receiver every time the truck reaches the corner of the side wall.

Therefore, a free bearing capable of slidingly contacting the top end surface of the side wall is attached to the lower end of the support shaft of the top end cleaning brush body, and a wheel receiver having at least a pair of front and rear wheels is provided beside the free bearing of the bogie. Direction mounting in the front-rear direction of the bogie, the front wheel once protrudes from the top end face at the top corner, and the direction is changed using only the free bearing as a fulcrum, so that the direction change is performed without complicated work be able to. However, in this case, if the direction of the bogie is changed immediately at the top corner, the cleaning of the side surface can be left unattended. After protruding from the end surface and moving the bogie with the free bearing and the rear wheel by the appropriate distance in the lateral direction at the top corner, operate the handle body to change the direction of the bogie and put the front wheel on the top surface By doing so, there is no possibility that the cleaning of the side surface of the top corner portion cannot be left.

Considering the difference in the size of the vertical gutter and the horizontal gutter of the cross type overflow gutter, it is preferable that the side cleaning brush body has a length for cleaning most of the side surface in the vertical direction. Cleaning the remaining side of the side is less burdensome than cleaning the entire area even if the operator cleans it manually with the deck brush. The burden can be greatly reduced. However, mounting all the cleaning brush bodies in one device is problematic in terms of portability and operability. Therefore, a separate device is configured and used in combination with the overflow gutter cleaning device according to the present invention. Good to do.

That is, according to the present invention, there is provided a cleaning device for cleaning a bottom of an overflow gutter of a settling pond in a sewage treatment plant,
A bogie having a handle body that can be gripped by an operator, a bogie that is moved along the bottom surface of the overflow gutter by pushing and pulling of the operator, and is rotatably supported by the bogie, and has a bottom surface of the overflow gutter. A bottom cleaning brush body for rotatingly contacting and cleaning at least a half portion of the width direction and at least a lower half of a side surface continuous with the bottom surface, and a driving unit for rotating the bottom cleaning brush body are provided. It is possible to provide an overflow gutter cleaning device for a sedimentation basin.

Further, a method of cleaning the overflow gutter by dividing the overflow gutter into a side wall and a bottom surface is also novel. That is, according to the present invention, when cleaning the overflow gutter of the sedimentation basin in the sewage treatment plant, the first
And using the second two cleaning devices, the first cleaning device is moved along the top end surface of the side wall of the overflow gutter by pushing and pulling by an operator, and the pair of side cleaning brush bodies sandwiches both side surfaces of the side wall. Then, the pair of side cleaning brushes are rotated to clean at least upper halves of both side surfaces of the overflow gutter, while the operator pushes and pulls the second cleaning device to the bottom surface of the overflow gutter. To move the bottom cleaning brush body into sliding contact with the bottom surface and the side surface of the side wall of the overflow gutter, and rotate the bottom cleaning brush body to at least half the width of the bottom surface of the overflow gutter and the bottom surface of the overflow gutter. A method for cleaning an overflow gutter of a sedimentation basin, characterized in that at least a lower half of a side surface connected to a bottom surface is cleaned.
