[0002] Water conservancy and hydropower engineering cultivates knowledge in surveying, planning, design, construction, scientific research and management of water conservancy and hydropower engineering. Among them, the use of gates is a facility to intercept water flow to raise the water level or regulate flow. Gates are often used in some ditches as control facilities to close and open drainage channels. They are an important part of hydraulic structures. When the gates intercept the water flow, the garbage in the ditches will also be intercepted by the gates and accumulated near the gates.

When these debris enter the water channel along with the water flow, it will cause blockage of the water channel, thereby reducing the efficiency of water flow. In severe cases, it will cause water to stagnate. At the same time, excessive accumulation will cause damage to the ecological environment.

[0023] See also Figure 1-Figure 4As shown, a flow interception and interruption device comprises a water flow channel 1 and a cleaning and collecting device 2; the cleaning and collecting device 2 is provided with a blocking plate 21, a plurality of fixed blocks 22 are fixedly installed on the top of the blocking plate 21, a transmission shaft 23 is penetrated and movably installed on one side of the plurality of fixed blocks 22, a torque motor 25 is fixedly installed on one end of the transmission shaft 23, two fixed gears 24 are penetrated and fixedly installed around the transmission shaft 23, one side of the two fixed gears 24 is respectively connected to a chain 26 for transmission, a plurality of movable rods 27 are fixedly installed between the two chains 26, and a plurality of hooks 28 are provided on one side of the plurality of movable rods 27;

[0024] During operation, the torque motor 25 transmits power to rotate the transmission shaft 23 and the fixed gear 24, which is beneficial to simultaneously transmit the chains 26 on both sides, so that the chains 26 drive the movable rod 27 and the hook claw 28 to move. When the hook claw 28 is working, it is beneficial to pick up debris on the water surface or in the water.

[0025] Furthermore, the water flow channel 1 is equipped with a fixing frame 11, an electric push cylinder 12 is fixedly installed on one side of the fixing frame 11, a push rod 13 is movably installed on the inner wall of the electric push cylinder 12, one end of the push rod 13 is hinged with a connecting block 14, and one side of the connecting block 14 is fixedly connected with a movable shaft 15;

[0026] During operation, during the operation of the electric push cylinder 12 , the push rod 13 moves in the inner wall of the electric push cylinder 12 , and the hinged connecting block 14 is linked by the movement of the push rod 13 , so that the connecting block 14 drives the movable shaft 15 to rotate relatively.

[0027] Furthermore, two fixed bearings 18 are fixedly installed on the top of the fixed frame 11, and movable shafts 15 are movably installed inside the two fixed bearings 18. Both ends of the movable shaft 15 are fixedly connected with linkage arms 16, and the other ends of the two linkage arms 16 are hinged with interception plates 17;

[0028] During operation, by installing the fixed bearing 18, the movable shaft 15 has enough space to move when rotating. At the same time, the movable shaft 15 links the linkage arm 16 to move to one side, and the other end of the linkage arm 16 drives the intercepting plate 17 to move up and down.

[0029] Furthermore, a fixing plate 32 is fixedly connected to one side of the fixing frame 11, and a collecting bucket 33 is placed on the top of the fixing plate 32;

[0030] During operation, the installation of the fixing plate 32 is helpful to support and load the collecting bucket 33 , so that the collecting bucket 33 can collect the sundries or garbage transported by the hook 28 during operation.

[0031] Furthermore, two limiting guide rails 19 are fixedly connected to one side of the fixing frame 11, and the inner walls of the two limiting guide rails 19 are movably mounted with retaining plates 17;

[0032] During operation, the fixing frame 11 fixes the limiting guide rail 19, and during the movement of the intercepting plate 17, the moving path of the intercepting plate 17 is limited to a certain extent, so that the intercepting plate 17 can better intercept and cut off the water flow.

[0033] Furthermore, two fixing rods 29 are fixedly connected to the inner wall of the fixing frame 11, and a blocking plate 21 is passed through and fixedly installed on one side of the fixing rod 29, and a plurality of flow slots 31 are opened on one side of the blocking plate 21;

[0035] Working principle: In embodiment 1, when the water flow is not intercepted, the transmission shaft 23 is rotated by driving the torque motor 25. When the transmission shaft 23 rotates, the chain 26 is transmitted through the fixed gear 24, so that the chain 26 rotates along both sides of the blocking plate 21. The blocking plate 21 blocks the garbage or debris driven by the water flow, and drives the movable rod 27 to move together during the rotation of the chain 26. At this time, the hook 28 fixed on the movable rod 27 salvages the garbage or debris in the water flow, so that the garbage or debris is transported to the top through the chain 26 in the water. When it is transported to the top, the hook 28 throws the garbage or debris into the inside of the collecting bucket 33, so as to clean up the debris in the water, which can protect the ecological environment while preventing the waterway from being blocked.

[0036] In the second embodiment, the electric push cylinder 12 is driven to move the push rod 13 to one side. The push rod 13 pushes the connecting block 14 during the movement, so that the connecting block 14 and the linkage 15 rotate inside the fixed bearing 18. The movable shaft 15 is rotated to make it the shaft to drive the fixed linkage arm 16 to rotate synchronously, so that one end of the linkage arm 16 gradually moves to one side. When the linkage arm 16 moves, it drives the intercepting plate 17 to move synchronously. When it reaches the top, the water flows. Similarly, when the push rod 13 shrinks inside the electric push cylinder 12, the linkage arm 16 drives the intercepting plate 17 to descend, so as to intercept and cut off the water flow.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
