As shown in fig. 1 and 2, the main body of the sluice is a reinforced concrete sluice body 11 constructed in a river channel, and a passage 12 for draining water is formed therein. The portal frame 13 is composed of two vertical beams and a cross beam, the two vertical beams are both fixedly mounted on the gate body 11 and are respectively located on two sides of the channel 12, and two ends of the cross beam are respectively fixedly connected with the two vertical beams and are located right above the channel 12.

As shown in fig. 3, two vertical beams of the gantry 13 are each provided with a slider 14, and the sliders 14 can slide on the vertical beams in a reciprocating manner. Each vertical beam of the portal frame 13 is also fixedly connected with two limit parts 4 for limiting the sliding range of the sliding block 14.

The first lifting device 15 is composed of an electric block and the like, and is installed on a cross beam of the portal frame 13, and a steel wire rope on the electric block is fixedly connected to the sliding block 14 and can pull the sliding block 14 to slide on a vertical beam of the portal frame 13. The swing arm 16 is hinged to the slider 14 and can swing and move up and down along with the slider 14.

The arc-shaped baffle 17 is fixedly connected to the swing arm 16 and can move along with the swing arm 16. An arc-shaped groove 18 is further formed in the bottom surface of the channel 12, and the curvature radius of the arc-shaped groove 18 is slightly larger than that of the arc-shaped baffle 17, so that the arc-shaped baffle 17 can smoothly slide into the arc-shaped groove 18 in the moving process.

A plurality of brackets 21 are welded on the inner wall of the arc-shaped baffle 17, and the height of each bracket 21 is 10-15 cm. The arc-shaped gate net 22 is fixedly connected on the support 21, barbs 23 are uniformly distributed on the arc-shaped gate net, and the barbs 23 face the arc-shaped baffle 17 and are used for hooking floating objects on the water surface, such as plastic bags and the like.

As shown in fig. 4, the swing of the swing arm 16 is achieved by pulling a driving device, the driving device is composed of a winding frame 31, a rotating shaft 32, a winding drum 33, a wire rope 34, a power device 35 and the like, the winding frame 31 is placed on the brake body 11, and two ends of the rotating shaft 32 are inserted into holes or bearing seats on the winding frame 31 and can rotate freely. The drum 33 is fixedly connected to the rotating shaft 32 and can rotate together with the rotating shaft 32. One end of the wire rope 34 is fixedly connected to the winding drum 33, the middle portion is wound on the winding drum 33, and the other end is fixedly connected to the swing arm 16. The power device 35 is composed of a motor and a speed reducer, the output end of the motor is connected with the input end of the speed reducer, and the rotating shaft of the speed reducer is connected with the rotating shaft 32 by a coupling, a belt transmission or a gear transmission and the like.

Referring back to fig. 1, the brake body 11 is embedded with a guide ring 36 during the construction process, and the cable 34 passes through the guide ring 36 and then is connected to the swing arm 16, so that the cable 34 between the guide ring 36 and the drum 33 is always in a horizontal state, and the drum 33 is stressed stably and does not bear overturning moment basically.

After the swing arm 16 is rotated to a predetermined position, it needs to be fixed, but the power device 35 in the driving device cannot be always in a power-on state, and in order to solve this problem, a limit ring 52 is installed on the wire rope 34, and correspondingly, a limit device for fixing the limit ring 52 is provided on the brake body 11. The limiting device comprises a blind hole 53 formed in the brake body 11 and a plurality of limiting rods 54 inserted into the blind hole 53, the number of the blind holes 53 is multiple, and the blind holes 53 correspond to different positions of the swing arm 16 respectively, so that after the swing arm 16 moves to different positions, the corresponding limiting rods 54 can be inserted into the limiting rings 52 on the steel wire rope 34, and then the limiting rods 54 are inserted into the corresponding blind holes 53.

The implementation principle of the embodiment is as follows:

in the normal use process, the channel 12 is closed by the arc-shaped baffle 17, and after the garbage in the river channel is contacted with the arc-shaped baffle 17, one part of the garbage is hung in the arc-shaped gate net 22 on the arc-shaped baffle 17, and the other part of the garbage is deposited in the arc-shaped groove 18 on the bottom surface of the channel 12.

When water is normally discharged, the arc-shaped baffle 17 rotates towards the direction close to the bottom surface of the channel 12, at the moment, water flows through the upper part of the arc-shaped baffle 17, and garbage on the arc-shaped baffle 17 and in the arc-shaped groove 18 cannot flow into a river channel below.

When maintenance operation is carried out, the arc-shaped baffle 17 slides into the arc-shaped groove 18 to scoop up the garbage in the arc-shaped groove 18, then the first lifting device 15 acts to pull the sliding block 14 to slide upwards, and at the moment, the swing arm 16 and the arc-shaped baffle 17 move out of the water surface together. The staff climbs onto the arc-shaped baffle 17 to clean up the garbage on the arc-shaped gate net 22.

When piling up silt is more between cowl 17 and the passageway 12 bottom surface, cowl 17 removes to the direction of keeping away from the passageway 12 bottom surface, appears a gap between the two this moment, and under hydraulic effect, the water velocity of gap department is fast, can carry out the rewashing to the silt of being detained, washes away it.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
