After the flood is discharged, the outer gate is lowered and the lower drainage channel is closed. Through the transmission relationship of the first gear assembly, the inner gate rises with the shaft, and the shaft rises with the fishing rod and the driven gear. When the driven gear rises to mesh with the third rack again, the driven gear rotates clockwise with the shaft, and the shaft rotates clockwise with the fishing rod. These fishing rods rotate upward, automatically fishing out the intercepted impurities from the water, and lifting them outside the gate through the curved structure. Therefore, when the gate discharges water, in addition to filtering impurities and preventing the downstream water channel from being blocked, it can also fish out large-sized impurities from the water, improving the functionality.

[0026] ​The inner gate plate 4 is internally provided with a plurality of fishing rods 10 arranged along the length direction of the inner gate plate 4, all the fishing rods 10 are jointly installed on a rotating shaft 11, the rotating shaft 11 is connected to a hinge seat 12 fixed on the inner gate plate 4, and a second gear assembly 13 is arranged between the rotating shaft 11 and the inner frame 2, when the inner gate plate 4 rises, the rotating shaft 11 is driven to rotate by the second gear assembly 13, and all the fishing rods 10 are deflected backward from the top end of the inner frame 2 by the rotating shaft 11.

[0027] The outer frame 1 is provided with a notch 17 on the side, the first gear assembly 5 comprises a connecting rod 18 fixed on the outer frame 1 and on the same side of the notch 17, a gear shaft 19 installed on the connecting rod 18, an intermediate gear 20 fixed on the inner frame 2 and on the same side of the gear shaft 19, a first gear rack 21 fixed on the outer gate plate 3 and a second gear rack 22 fixed on the inner gate plate 4, one end of the gear shaft 19 extends out of the outer frame 1 and is engaged with the intermediate gear 20, the intermediate gear 20 is located on the movement route of the second gear rack 22, and the other end of the gear shaft 19 extends into the outer frame 1 and is located on the movement route of the first gear rack 21.

[0028] The second gear assembly 13 comprises a driven gear 23 fixed on one end of the rotating shaft 11, and further comprises a third gear rack 24 fixed on the inner wall of the inner frame 2, the third gear rack 24 is located on the outer side of the driven gear 23, when the inner gate plate 4 rises with the rotating shaft 11 and the driven gear 23 is engaged with the third gear rack 24, the rotating shaft 11 is driven to rotate clockwise by the driven gear 23, and all the fishing rods 10 are rotated upward by the rotating shaft 11; conversely, when the inner gate plate 4 descends with the rotating shaft 11 and the driven gear 23 is separated from the third gear rack 24, the fishing rods 10 are rotated downward under the action of gravity.

[0029] The top end of the inner frame 2 is provided with a chamfer 25 inclined downward toward the direction of the fishing rods 10.

[0030] The fishing rods 10 are curved rods gradually curved toward the inner side direction, gaps are arranged between every adjacent two fishing rods 10, and all the fishing rods 10 are connected together by steel wires.

[0031] The outer gate plate 3 and the inner gate plate 4 are provided with rubber sealing strips on the four edges.

[0032] The top end of the outer gate plate 3 is connected with a hanging ring 14, and the top of the outer frame 1 is provided with a through groove 15 in the same height and in a straight line with the hanging ring 14.

[0033] Working principle and effect: Fixing holes are provided at the four corners of the outer frame 1 and the inner frame 2. The outer frame 1 and the inner frame 2 are fixed to the gate through the fixing holes. The inner frame 2 is located inside the gate, and the outer frame 1 is located outside the gate. A winch is installed at the top of the gate or other positions. The wire rope on the winch is connected to two hanging rings 14. When the gate is closed, the two hanging rings 14 press... Figure 4 As shown, the outer gate 3 is located on the lower side and covers the outside of the lower drainage channel 8, thus closing the lower drainage channel 8. The inner gate 4 is located on the upper side and covers the inside of the upper drainage channel 9, thus closing the upper drainage channel 9. Since the inner gate 4 is equipped with a filter screen 6, the upper drainage channel 9 is closed by using the filter screen 6. When the water level rises to the filter screen 6, it will pass through the mesh and be discharged outward through the upper drainage channel 9, realizing automatic flood discharge and reducing water pressure. When the water level is lower than the filter screen 6, the water discharge stops. Conversely, when it is necessary to draw water from the reservoir or to quickly discharge floodwater, the winch is started to wind the wire rope, which pulls the hanging ring 14 upward. The hanging ring 14 drives the outer gate plate 3 to rise, which in turn drives the first rack 21 to rise. The first rack 21 meshes with the inner end of the gear shaft 19 to rotate, and the outer end of the gear shaft 19 meshes with the intermediate gear 20 to rotate. The intermediate gear 20 meshes with the second rack 22 to move linearly, and the second rack 22 drives the inner gate plate 4 to descend. The inner gate plate 4 carries the filter screen 6 down below the water level, allowing the reservoir water to pass through the filter screen 6 and be discharged outward. This achieves the purpose of rapid discharge through human intervention. At this time, the drainage volume is large, and impurities in the reservoir water (such as dead branches and leaves, weeds, etc.) are intercepted by the filter screen 6 on the reservoir side, preventing them from being directly discharged into the water channel and causing blockage.

[0034] like Figure 5 As shown, in another embodiment, several louvers 7 are hinged between the top of the outer gate 3 and the top of the outer frame 1. Each pair of adjacent louvers 7 are hinged together, and the two ends of the louvers 7 extend into the tracks on both sides of the outer frame 1 and slide in the tracks via pulleys. When the outer gate 3 descends, in addition to causing the inner gate 4 to rise and close inside the upper drainage channel 9, the louvers 7 are also stretched to close outside the upper drainage channel 9. At this time, the louvers 7 intercept the outside of the filter screen 6. By using the relatively closed manner of the louvers 7, water discharge is reduced, and the gate is relatively closed (relatively means that the hinge gap between the two louvers 7 can still drain water, which has the advantage of reducing water pressure and less drainage). Conversely, when the outer gate 3 rises to the outside of the upper drainage channel 9, in addition to causing the inner gate 4 to descend to the inside of the lower drainage channel 8, the louvers 7 are also folded onto the upper drainage channel 9. At this time, the lower drainage channel 8 is opened, and the filter screen 6 intercepts and filters the water outward.

[0035] It is worth noting that when the inner gate plate 4 descends to the lower drainage channel 8, it is when the gate is releasing water (the gate is open), and when the inner gate plate 4 rises to the upper drainage channel 9, it is when the gate is storing water (the gate is closed). When the inner gate plate 4 descends, it also pulls the scoop rod 10 down, which in turn pulls the rotating shaft 11 down. The rotating shaft 11 then pulls the driven gear 23 down. The driven gear 23 is engaged with the third rack 24 and rotates counterclockwise. The driven gear 23 drives the rotating shaft 11 to rotate counterclockwise, and the rotating shaft 11 drives the scoop rod 10 to rotate downwards. The driven gear 23 disengages from the third rack 24, and while continuing to descend, the rotating shaft 11 presses the scoop rod 10 down. Figure 8 As shown, the rods 10 are placed downwards on the inner gate plate 4. These rods 10 are equivalent to adding another interception barrier inside the filter screen 6. When the water is discharged through the mesh of the filter screen 6, larger impurities are intercepted in advance by the rods 10, and smaller impurities are intercepted by the filter screen 6, achieving the purpose of double interception. After the larger impurities are intercepted, they still need to be cleaned outwards. This invention can achieve this function mainly in the following ways: After the flood discharge is completed, the outer gate plate 3 descends and closes the drainage channel 8. Through the transmission relationship of the first gear assembly 5, the inner gate plate 4 will rise with the rotating shaft 11. The rotating shaft 11 will carry the rods 10 and the driven gear 23 to rise. When the driven gear 23 rises to mesh with the third rack 24 again, the driven gear 23 will rotate the rotating shaft 11 clockwise, and the rotating shaft 11 will carry the rods 10 to rotate clockwise. Finally, these rods 10 will... Figure 3 Figure 4 The shape rotates upwards. Since these fishing rods 10 are bent inwards, when they rotate upwards, their bending direction is outwards. They automatically scoop out the intercepted impurities from the water and lift them out of the gate through the bending structure. Therefore, when the gate releases water, in addition to filtering impurities and preventing blockage of the downstream water channel, it can also scoop out large-sized impurities from the water, improving functionality. In actual installation, a discharge channel or discharge bucket can be set at the top of the outer frame 1. The discharge channel or discharge bucket is inclined, with the high end of the inclination located at the bottom side of the fishing rod 10 and the low end extending towards the gate end. The scooped impurities fall into the discharge channel after being flipped by the fishing rod 10, and are discharged to the gate end after being guided by the inclined discharge channel.
