DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a simple structure for setting a relatively small-scale intake and a headrace,
The present invention relates to a simple dust remover that can reduce manufacturing costs, maintenance costs, and the like.

[0002]

2. Description of the Related Art As a conventional dust reducer, a full width rake is moved up and down by a rotary chain or a plurality of wire ropes on a grid-like screen provided for catching dust in flowing water. A large-scale full-scale duster equipped as shown was generally used. For this reason, enormous costs were required for production and its management and maintenance. Therefore, it was not economical to attach such a large-sized dust remover to an intake port of a river with relatively little garbage. For this reason, in such an intake, dust was conventionally removed manually using a rake. However, manual work involves dangers and is hard work, so that sufficient dust removal results cannot be obtained.

Accordingly, the present inventors have disclosed in Japanese Patent Application Laid-Open No. 8-74222.
No. 7 has already proposed a simple dust remover. It supports a suspension rail horizontally above a screen provided in a waterway, suspends a suspension frame so as to be movable along the suspension rail, and rotates the suspension frame by a drive unit such as a handwheel. Wire drum, to move
And a wire guide for guiding a wire wound on the wire drum is provided, a rake is provided at a lower end of a pole suspended from the suspension frame into a waterway, and a tip of the wire is fastened to the rake. By winding the wire by rotating the wire drum, the rake is slid to the front of the screen to be raised from the waterway, or to be lowered away from the front of the screen,
The structure is simple, and even if the rake width is less than the width of the screen, the rake can be brought into contact with the entire width of the screen by moving the suspension frame horizontally. Since a small rake can sufficiently remove dust, there is an advantage that manufacturing and maintenance costs are not required.

[0004]

However, in the above-mentioned simple dust remover, when the rake is lowered away from the front of the screen, the wire is pulled forward by operating the lever and projecting the wire guide forward. However, such an operation using a wire guide does not always allow the rake to be sufficiently separated from the front surface of the screen when descending, so that there is a disadvantage that a large amount of dust cannot be removed properly. In addition, since the rake could only contact the screen due to its own weight, it was difficult to scoop up dust that had stuck to the screen.

[0005]

In order to achieve the object, a simple dust remover according to the present invention comprises a traveling frame that horizontally supports a suspension rail above a screen provided in a waterway and is movable in the waterway width direction along the suspension rail. A guide roller group for attitude control is supported on the traveling frame by a power cylinder so as to be able to swing in the water channel direction, and a rake is fixed to the lower end of a long pole orthogonally so that dust is picked up. A tool is formed, the pawl is supported by the guide roller group so as to be able to move forward and backward, a wire drum is provided on the traveling frame, and the tip of the wire wound around the wire drum is used as the dust scraping tool. By fastening the dust collecting device to the lower portion, the dust collecting device is suspended by the wire, and the rotation of the wire drum raises and lowers the dust collecting device so that the rake can come and go in the waterway, and the power cylinder is operated. By Guide rollers by swinging attitude of 該塵 garbage 掻揚 tool, characterized in that the rake is controlled and adapted to be contact with or is separated in front of the screen.
