The turntable will drive the screw to rotate, and the screw will move up and down under the action of the screw nut, thereby driving the gate to move up and down, which is very convenient and fast. In this scheme, the gate is driven up and down by a screw. However, since the entire mechanism is completely outdoors, the screw is in contact with the air for a long time, and the humid air will cause the surface of the screw to be corroded and rusted, making the subsequent rotation of the screw difficult. Therefore, a small channel water gate is urgently needed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In order to solve the problem that the screw rod on the gate is easily corroded and rusted by humid air, Figure 1-Figure 3 As shown, the utility model provides: a small channel sluice gate, including a base 1 installed on both sides of the canal, the base 1 has a slide groove on one side close to each other, and the two ends of the valve 2 slide in the slide groove, a gantry 3 is installed on the base 1, and a lifting mechanism 4 for the up and down movement of the valve 2 is installed on the gantry 3, and the lifting mechanism 4 includes two connecting columns 5 fixedly arranged on the upper part of the valve 2, the upper end of the connecting column 5 is threadedly connected with a screw rod 6, the surface fixed sleeve of the screw rod 6 is provided with a protective sleeve 7, the bottom end port fixed sleeve of the protective sleeve 7 is provided with a sealing ring 9, the sealing ring 9 is movably abutted against the surface of the connecting column 5, the protective sleeve 7 is movably sleeved on the surface of the connecting column 5, the upper ends of the two screw rods 6 are connected with a driving unit 8, and the driving unit 8 is driven to rotate by the screw rod 6, and the rotation will cause the connecting column 5 threadedly connected to the screw rod 6 to move up, and in this process, the protective sleeve 7 is always sleeved on the surface of the screw rod 6 to isolate the external air from contacting the surface of the screw rod 6, so as to prevent the screw rod 6 from being corroded and rusted by humid air when outdoors.
[0023] In order to solve the problem of large resistance of the screw rod 6 when it rotates, the driving unit 8 includes a gear box 801 fixed on the upper end surface of the gantry 3, and two gears 1 802 and a gear 2 803 are rotatably installed in the gear box 801.
