A conical block matching the conical groove of the driving sleeve 210 is fixed on the driving rod. The driving motor 207 of the driving structure 2 drives the bidirectional threaded rod 204 through the reducer 206 for transmission. The bidirectional threaded rod 204 can enable the two sets of threaded blocks to transmit in opposite directions, so that its first connecting rod 203 can change the distance between the driving plate 208 and the top of the fixed cover 201. The fixed cover 201 is fixedly installed on the blocking plate 304 of the gate structure 3, so that its driving plate 208 can adjust the transmission block position of the adjustment structure 4 through the driving sleeve 210 and the driving rod. The hydraulic rod 202 is connected to the hydraulic drive device of the gate, so that it can drive the gate structure 3 up and down as a whole, thereby controlling the opening and closing of the on-off gate 102.

[0030] The gate structure 3 includes an on-off gate 301, an adjusting groove 302, a matching inclined groove 303, and a blocking plate 304.

When the first transmission block 402 is transmitted downward, it will be transmitted to the adjustment block 401 through the first inclined surface 406. At this time, the adjustment block 401 will slide outward through the adjustment groove 302, so that the adjustment block 401 protrudes and fits the inclined groove 303, and then the water body is discharged through the water outlet 104. The adjustment block 401 is subjected to an upward impact force, and the on-off gate 301 generates an upward lift, thereby improving the efficiency of the gate's upward transmission.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0033] After the water inlet 103 of the gate structure 1 is opened through the gate structure 3, the water flow can be discharged through the water outlet 104. The on-off gate body 101 is generally installed at the river gate. The driving motor 207 of the driving structure 2 drives the bidirectional threaded rod 204 through the reducer 206 for transmission. The bidirectional threaded rod 204 can make the two sets of threaded blocks transmit in opposite directions, so that its first connecting rod 203 can change the distance between the driving plate 208 and the top of the fixed cover 201. The fixed cover 201 is fixedly installed on the blocking plate 304 of the gate structure 3, so that the driving plate 208 can adjust the position of the transmission block of the adjustment structure 4 through the driving sleeve 210 and the driving rod. The hydraulic rod 202 is connected to the hydraulic drive device of the gate, so that it can drive the gate structure 3 up and down as a whole, thereby controlling the opening and closing of the on-off gate 102 and the on-off gate 30 1 can fit with the on-off gate 102, so that the gate can be blocked in the on-off gate 102, blocking its water inlet 103 and water outlet 104. The pressure relief hole of the blocking plate 304 facilitates the pressure relief of the adjustment structure 4 transmission and facilitates the introduction of water into the on-off gate 301, thereby increasing the overall density of the on-off gate 301 and improving the transmission efficiency. When the first transmission block 402 is transmitted downward, it will transmit with the adjustment block 401 through the first inclined surface 406. At this time, the adjustment block 401 will slide outward through the adjustment groove 302, so that the adjustment block 401 protrudes and fits the inclined groove 303, and then in the process of the water flowing out through the water outlet 104, the adjustment block 401 is subjected to an upward impact force, thereby generating an upward lift for the on-off gate 301, thereby improving the efficiency of the gate's upward transmission.
