Dirt is cleared up while blocking dirt.A kind of easy to clean trash rack of small hydropower station of the utility model, is being blocked using scraping teeth
While dirty, moreover it is possible to realize clearing function.In dam front end by drain grating, floating pollutant is blocked in drain grating power station sewage
Before, the driving device of scraping scraped in axis is cleared up, driving gear is rotated, mutually nibbled between the tooth band being arranged on gear and sliding rail
It closes, gear can be moved up and down along sliding rail, and cleaning scraping is driven to clear up drain grating.
Further, the length of the sliding rail is consistent with the grid leaf length of grid body.The length of sliding rail is consistent with grid leaf length,
The movable length for clearing up scraping can be made to guarantee covering full wafer grid leaf, grid leaf is enable to be sufficiently cleaned.
Further, the equivalent width of the width for scraping axis and grid body.The movable length for clearing up scraping can be made to guarantee
All grid leaves are covered, all grid leaves is enable to be sufficiently cleaned.
Further, roller bearing is connected with by chain at the top of grid body, control motor, the setting of roller bearing both ends is provided on roller bearing
There is first gear, second gear is provided with by first gear, first gear is connected with second gear by chain.By in grid body
The gear of control motor control is set, can be convenient folding grid body, convenient for repairing inspection to grid body.
Further, it is described scrape tooth plate with scrape axis and connect using buckle structure.When cleaning scraping after a period of work, clearly
Scraping on tooth plate attachment winding there are many dirt on clean scraping, be connected by a snap can make to clean scraping to scrape tooth plate quick detachable,
It is convenient that scraping is cleared up.
Further, described to scrape tooth plate number at least two.The scraping teeth number for scraping tooth plate is directly proportional to cleaning effect, scrapes
Tooth plate quantity is more, and the scraping teeth for scraping tooth plate is more, and cleaning effect is better.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. a kind of easy to clean trash rack of small hydropower station of the utility model cleans scraping by setting, clears up drain grating
On dirt.
2. a kind of easy to clean trash rack of small hydropower station of the utility model can make to clean scraping by the way that gear is arranged
It moves up and down, is more convenient cleaning laborsaving.
3. a kind of easy to clean trash rack of small hydropower station of the utility model, the tooth of the motor control by the way that grid body is arranged in
Wheel can be convenient folding grid body, convenient for repairing inspection to grid body.
4. a kind of easy to clean trash rack of small hydropower station of the utility model, knot is snapped connection with scrape axis by scraping tooth plate
Structure, can make to clean scraping to scrape tooth plate quick detachable, it is convenient that scraping is cleared up.
