For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] As Figures 1-4As shown, a gate structure applied to a river channel, comprising a lifting gate and a plurality of strong discharge assemblies arranged in a horizontal linear array at the bottom end of the lifting gate, each strong discharge assembly comprising a mounting channel opened on the lifting gate and a filter type water pump fixed in the mounting channel, the upstream of the river channel 7 is also provided with a water level gauge 8 for detecting the water level, the water level gauge 8 is electrically connected with the filter type water pump and a lifting drive motor 2 for controlling the lifting of the lifting gate through a controller, realizing that when the upstream water level is higher than the set water level, the lifting gate is closed and the filter type water pump is opened for strong discharge.

[0028] Specifically, the filter type water pump comprises a water pump body 5 fixed in the mounting channel and a filter screen 6 clamped at the water inlet and outlet of the water pump body 5, which can prevent pollutants in the river channel 7 from entering the water pump body 5 and causing damage to the water pump body 5.

[0029] The lifting gate comprises a gate body 4 and a synchronous lifting assembly arranged on the gate body 4, and the synchronous lifting assembly is connected with the lifting drive motor 2 fixed on the prefabricated fixed plate. The synchronous lifting assembly comprises a plurality of screw rods 9 arranged in a horizontal linear array and uniformly rotating at the top end of the gate body 4, the top end of each screw rod 9 penetrates through the fixed prefabricated plate 3, and the screw rod 9 is connected with the internal thread of the screw sleeve 1 after penetrating through the fixed prefabricated plate 3, the outer part of the screw sleeve 1 is coaxially fixed with a synchronous sprocket 10, a plurality of synchronous sprockets 10 are connected through a synchronous chain 12, and the synchronous chain 12 is connected with the lifting drive motor 2 through a drive sprocket 11; the bottom end of the screw sleeve 1 is also horizontally rotatably connected with the fixed prefabricated plate 3, and two screw rods 9 are arranged in the embodiment, and the two screw rods 9 are symmetrically arranged about the center line of the gate body 4, so that the lifting is more stable.

[0030] The tooth number ratio of the drive sprocket 11 to the synchronous sprocket 10 is 1:2, which improves the lifting efficiency.

[0032] The above structure realizes the following working mode: when the water level gauge 8 collects that the upstream water level rapidly rises to the upper limit value, the screw sleeve 1 is driven to rotate by controlling the lifting drive motor 2, the screw rod 9 is driven to descend under the action of the thread, and then the gate body 4 is driven to descend, until sealing, and then the water pump body 5 is opened, the upstream water is discharged to the downstream, avoiding waterlogging;

[0033] When the water level gauge 8 collects that the upstream water level is lower than the lower limit value, the gate body 4 is controlled to close the river channel 7, and the water pump body 5 is controlled to rotate reversely, the downstream water is discharged to the upstream, and the minimum water level of the upstream of the river channel 7 is maintained;

[0034] At the same time, when the silt appears in the upstream, the sluice body 4 is also used to close the river channel 7, the water pump body 5 is reversely rotated, the silt in the upstream river channel 7 is washed by the downstream water, after the washing setting time, the sluice body 4 is opened and the water pump body 5 is closed, and the upstream water flows into the downstream.

[0035] It should be noted that the above electronic components are all mature products in the market, and the embodiment only needs to be connected according to the instruction manual after purchasing, and is not improved, so the circuit connection structure and principle are not described here.

[0036] Therefore, the gate structure applied to the river channel adopts the above structure, the strong discharge assembly is arranged, the upstream water can be discharged to the downstream when the heavy rainfall occurs in the upstream, the urban waterlogging is avoided, the downstream water can be discharged to the upstream when the water level in the upstream is too low, the minimum water level of the river channel is ensured, and the urban microclimate is conveniently adjusted.
