Next, the operation of the above structure will be described. The water in the water channel 41 flows from the water intake port 45 to the water diversion channel 43, and the debris is supplemented by the vertical rod 5 and the horizontal screen member 6.
The debris-removed water is taken into 43. When dust is collected on the screen 1, the reciprocating drive means 25
Thus, the scraping body 32 provided on the moving body 22 is moved along the front surface 7 of the screen 1 from the waterway upstream side J toward the waterway downstream side K. By this outward movement, the scraping claw of the scraping body 32
The scraps 34 scrape off the debris while moving between the horizontal screen members 6, the scraped debris is flowed and removed downstream by the flow of the water channel 41, and the scraper 32 is left on the screen 1. Since it moves over the crosspiece 3L to the downstream side K of the water channel, it is possible to reliably flow the refuse to the water channel 41.
In this case, since the tip 6B of the horizontal screen member 6 facing the downstream side K of the water channel is a free end, dusts can be easily scraped off from the tip 6B. Further, the prime mover 20 is stopped at a position beyond the left crosspiece 3L and the scraping body 32 is waited for a predetermined period of time, during which dusts attached to the scraping claws 34 are also removed by the flow of the water channel 41. After that, the moving body 22 is rotated together with the guide rail 11 by the rotation drive means 26 to remove the scraping body.
32 is rotated to a substantially parallel position to be positioned on the water surface of the water channel 41, and this rotation causes the scraping claw 34 to separate from between the horizontal screen members 6. After this, the reciprocating drive means 25 moves the scraping body 32 to the waterway upstream position J of the screen 1, and after this return path movement, the rotation driving means 26 scrapes from the horizontal position to the vertical position along the front surface 7 of the screen 1. The body 32 is rotated, the scraping claw 34 is inserted between the horizontal screen members 6, and the scraping body 34 is moved to the downstream side K of the water channel to scrape off dusts in the same manner as described above. Further, since the scraping body 32 can be stored in the right step portion 44R in a substantially vertical state when the dust removing device 10 is stopped, the scraping body 32 does not get in the way and the water in the water channel 41 does not directly hit. Also, dust and dirt will not adhere to the scraping body 32. Also, the scraping body 32 is the screen 1
Since the sliding ring 33 slides on the upper bar 2U of the frame body 4 when moving in parallel along the front surface of the screen, the scraping body 32 can be accurately aligned with the screen 1 and the scraping body 32 can be scraped. The body 32 can be moved smoothly.
