Description

Technical Field

[0001] The utility model relates to a gate, in particular to a hydraulic gate with high-precision adjustable lifting and lowering, belonging to the technical field of hydraulic engineering. Background Art

[0002] In the prior art, for example, a utility model with publication number 202221906306.X discloses a lifting type hydraulic gate for a water conservancy project. By setting a side guard frame, a lifting gate, and a driving mechanism, the lifting gate can be lifted and lowered stably, which is convenient for adjustment. At the same time, the driving mechanism ensures that both sides are lifted and lowered synchronously to avoid jamming. Through the cooperation between the lifting gate and the driving mechanism, the lifting height of the lifting gate can be flexibly adjusted according to actual needs, which is convenient for adaptation.

[0003] Similar to the above application, there are still some shortcomings:

[0004] 1. Only the screw is used to control the gate lifting and lowering. Although the height adjustment is highly accurate, the gate opening rate is relatively slow, which affects the flood discharge rate;

[0005] 2. Although impurities can be filtered during drainage, they cannot be cleaned. The accumulation of impurities will cause blockage of the interception plate, affecting the drainage rate;

[0006] Therefore, a high-precision hydraulic gate with adjustable lifting is designed to optimize the above-mentioned problems. Utility Model Content

[0026] The overall working principle is: when the gate is opened for use, first start the lifting motor 7 to drive the rope reel 9 on the shaft 8 to rotate, retract the steel cable 10, lift the height of the gate 3, and make a rough adjustment of the height. Then use the rotating mechanism 6 to control the rotation of the first bevel gear 5, control the lifting and lowering of the screw 4, and then finely adjust the position of the gate 3 to ensure the gate adjustment rate while ensuring the adjustment accuracy. In addition, in the process of opening the gate to discharge flood water, the conveying mechanism is used to convey the garbage on the liquid surface upward to ensure the drainage rate.

[0027] In this embodiment, two groups of rope reels 9 are provided, and the steel cables 10 wound on the rope reels 9 are respectively fixed at symmetrical positions on both sides of the top of the cross plate 2.

[0028] Local working principle: two sets of steel cables 10 are used to pull at both ends of the transverse plate 2, thereby ensuring the stable lifting and lowering of the transverse plate 2 and reducing the bearing capacity of the steel cables 10.

[0029] In this embodiment, an upper protective cover 21 is provided on the top of the bracket 1, and the lifting motor 7, the shaft rod 8 and the rope reel 9 are all located inside the upper protective cover 21, and the end of the shaft rod 8 is rotatably connected to the inner end of the upper protective cover 21.

[0030] Partial working principle: The upper protective cover 21 is used to protect the lifting motor 7, the shaft rod 8 and the rope reel 9.

[0031] In this embodiment, guide grooves are provided on both sides of the interior of the bracket 1, and the ends of the cross plate 2 and the gate 3 are both located inside the guide grooves.
