The working principle is that the filter screen 72, the expansion plate 73 and the dirt cleaning plate 61 are kept horizontal at the bottom of the channel 1 at first, the circulation of water flow and sundries is not affected, and the sundries in the water flow are intercepted by the dirt blocking grating 5 when the water flow passes through the dirt blocking grating 5.

When sundries intercepted at the trash rack 5 are accumulated to a certain extent and influence water flow to normally pass through, the motors 21 on the two sides of the mounting plate 12 are started, the motors 21 start to operate and drive the winding wheel 31 to rotate, the winding wheel 31 winds the steel wire rope 32, the steel wire rope 32 slides on the cableway 43, and meanwhile the trash cleaning plate 61 is pulled, so that the trash cleaning plate 61 moves upwards along the first slide way 41 and the second slide way 42 in a horizontal state.

In the process of upward movement of the trash plate 61, the trash plate 61 scrapes off shellfish, algae and sundries adhered to the surface of the trash rack 5, and simultaneously, the inclined blocks 65 push out the sundries between the plurality of grid bars 53 to the direction close to the trash plate 61, so that blocking is prevented when water flows through, and the shellfish, algae and sundries adhered between the plurality of grid bars 53 are scraped off.

When the dirt removing plate 61 moves to the arc section position, the arc groove 67 on the fixing block 66 is abutted against the fixed shaft 51, the dirt removing plate 61 rotates along the arc section with the fixed shaft 51 as the center towards the direction close to the collecting bin 81 under the traction of the steel wire rope 32, and impurities are poured into the collecting bin 81.

In the process of upward movement of the dirt removing plate 61, one end of the filter screen 72 and one end of the telescopic plate 73 are lifted, and as the telescopic plate 73 is hinged with the dirt removing plate 61 and the elastic sheet 64 fixed on the telescopic plate 73 deforms along with the decrease of the rising angle of the dirt removing plate 61, the elastic sheet 64 gradually moves towards the convex strip 63 at the bottom of the dirt removing plate 61, when the dirt removing plate 61 continues to rise, the elastic sheet 64 passes over the convex strip 63 and hits the dirt removing plate 61 for many times, so that the dirt removing plate 61 vibrates, and sundries can slide into the collecting bin 81 more smoothly due to the fact that the vibration is matched with the inclination of the dirt removing plate 61.

Meanwhile, when one end of the filter screen 72 and one end of the telescopic plate 73 are lifted, the balancing weight 71 is always clung to the bottom of the channel 1, so that the filter screen 72 is inclined, as the dirt cleaning plate 61 continues to move upwards and is inclined, the telescopic plate 73 stretches to adapt to the height of the position of the hinge shaft 62 on the dirt cleaning plate 61, and the inclined filter screen 72 intercepts sundries, so that the sundries are prevented from flowing below the dirt cleaning plate 61 and accumulating under the impact of water flow, and therefore subsequent cleaning is difficult.

When the cleaning work is completed, the motor 21 reversely rotates to drive the winding wheel 31 to reversely rotate, so that the steel wire rope 32 is unreeled, the trash cleaning plate 61 resets along the first slide way 41 and the second slide way 42 under the action of self gravity, the trash cleaning plate 61 pushes the filter screen 72 to be horizontal in the descending process of the trash cleaning plate 61, and the bottom of the balancing weight 71 is provided with balls to prevent the filter screen 72 from being clamped in resetting. When the dirt removing plate 61 enters water and moves to the bottom of the channel 1, the filter screen 72 does not intercept sundries, the sundries are accumulated to the position of the dirt blocking grating 5 again under the action of water flow, the sundries intercepted by the filter screen 72 are pushed by the balancing weight 71 to a direction away from the dirt blocking grating 5 at the bottom of the channel 1, and when the filter screen 72 returns to the horizontal position, the sundries are accumulated to the position of the dirt blocking grating 5 again beyond the balancing weight 71, and the next cleaning is waited.

After the sundries in the collecting bin 81 are fully accumulated, the sundries in the collecting bin 81 are cleaned, so that the whole water conservancy trash rack 5 device can continuously and normally work.

Further, when it is desired to intercept the finer debris, the motor 21 is started, and the motor 21 drives the cleaning plate 61 to move along the slideway until the filter screen 72 tends to be vertical and is kept in this state all the time, so that the filter screen 72 is placed in front of the trash rack 5, and the filter screen 72 intercepts the finer debris.

While embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the invention.
