[0030] In the embodiment, a plurality of annular sealing pads 54 are arranged in the inner cavity of inlet pipe 51, and the diameter of annular sealing pad 54 is approximately equal to that of steel cable 23, the thickness of multiple annular sealing pads 54 is gradually increased, and the plurality of annular sealing pads 54 can divide the inner cavity of inlet pipe 51 into multiple sections, so that the part of the inner cavity of inlet pipe 51 close to sealing box 4 can be kept dry, thereby avoiding a large amount of water in the water channel from entering after sealing box 4 is filled with water, and ensuring that the internal structure of sealing box 4 remains dry.
[0031] The sealing box 4 is internally provided with a support wheel shaft rotating disc anti-rust and moisture-proof unit.
[0032] The support wheel shaft rotating disc anti-rust and moisture-proof unit comprises a compression-resistant part, which comprises a stabilizing seat 45, the stabilizing seat 45 is provided in two groups, the two groups of stabilizing seats 45 are symmetrically installed on the inner walls of the sealing box 4, the top of the stabilizing seat 45 is provided with a ring-shaped keel frame 44, the ring-shaped keel frame 44 is provided in several groups at intervals, the inner bottom of the sealing box 4 is provided with a fixed seat 46, and adjacent fixed seats 46 are provided with a tightening winch 47.

[0034] In the embodiment, when the steel cable 23 directly passes through the first-stage diaphragm 52 and the second-stage diaphragm 53 in the installation frame 5, the static friction between the first-stage diaphragm 52 and the second-stage diaphragm 53 is large due to the mutual attachment of the first-stage diaphragm 52 and the second-stage diaphragm 53, the first-stage diaphragm 52 and the second-stage diaphragm 53 can further block and adsorb the water on the surface of the steel cable 23, then the steel cable 23 will be wound by the tightening winch 47 after passing through the moisture-proof cotton block 43, and the moisture-proof cotton block 43 will further adsorb the water on the surface of the steel cable 23, so as to further reduce the humidity of the steel cable 23 area and ensure the dryness of the structure of the tightening winch 47 area.
[0035] Working principle: in the process of using the device, the operator can slowly release the steel cable 23 wound on the surface of the tightening winch 47 in the sealing box 4 by driving the tightening winch 47, when the steel cable 23 is elongated, the tension between the fixed seat 46 and the fixed frame 21 becomes smaller, the horizontal gate 3 will be actively turned over along the gate side sliding channel 11 on the surface of the side gate plate 1 under the guidance of the side partition plate 31 and the guide pulley 32, and will be turned to a vertical state by the continuous elongation of the steel cable 23, and will be sealed and combined in the inner bottom of the gate side sliding channel 11 when the horizontal gate 3 is turned to a vertical state, so as to ensure the sealing and blocking of the horizontal gate 3 to the water channel;

[0037] When the horizontal gate 3 needs to be reset to reopen the waterway, the external steel cable 23 can be slowly recovered by driving the tightening winch 47 installed inside the sealing box 4, and in the recovery process, the external steel cable 23 will enter through the inlet pipe 51, and the annular sealing pads 54 inside the inlet pipe 51 will block the water on the surface of the steel cable 23 in the first stage, reducing the water flow attached to the surface of the steel cable 23, and when the steel cable 23 enters the installation frame 5, when the steel cable 23 passes through the first-stage diaphragm 52 and the second-stage diaphragm 53 inside the installation frame 5, since the first-stage diaphragm 52 and the second-stage diaphragm 53 are in close contact with each other, the static friction between the first-stage diaphragm 52 and the second-stage diaphragm 53 is large, and the first-stage diaphragm 52 and the second-stage diaphragm 53 can further block and adsorb the water on the surface of the steel cable 23, and then the steel cable 23 will pass through the moisture-proof cotton block 43 and be wound by the tightening winch 47, and the moisture-proof cotton block 43 will adsorb the water on the surface of the steel cable 23 again, thereby further reducing the humidity of the steel cable 23 area and ensuring the dryness of the structure of the tightening winch 47 area.
