In water conservancy projects, sluices are widely used as structures for retaining, discharging or taking in water. A lifting device is required when the gate needs to be opened, and different sized gates are selected for adjustment and control according to the size of the gate openings.

[0003] The existing gate lifting device has the problem that the entire lifting device is also immersed in water along with the gate, and long-term immersion may cause corrosion damage to the lifting device. Therefore, a water conservancy and hydropower gate lifting device is needed. Utility Model Content

[0006] Preferably, the second bevel gear forms a transmission structure through the first bevel gear and the turning knob, and the screw forms a lifting structure through the second bevel gear and the fixing frame.

[0007] Preferably, the locking mechanism comprises a threaded ring, a transmission rod, a buckle and a fixed shaft, the transmission rods are rotatably mounted on both sides of the threaded ring, the ends of the transmission rods are rotatably connected to the buckles, and the sides of the buckles are connected to the fixed shaft.

[0008] Preferably, the buckle forms a rotating structure through the fixed shaft and the connecting frame, and the buckle forms a transmission structure through the transmission rod, the threaded ring and the adjusting rod.

[0009] Preferably, the connecting frame forms a snap-fit ​​structure with the biting plate through a buckle, and the biting plate forms a lifting structure with the sliding frame through a screw rod.

[0010] Preferably, connecting rods are provided on both sides of the fixing frame, the ends of the connecting rods are connected to mounting plates, positioning bolts are passed through the tops of both ends of the fixing frame, the mounting plates form a snap-fit ​​structure with the fixing frame through the positioning bolts, and the mounting plates form a sliding structure with the fixing frame through the connecting rods.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting up a sliding frame, the fixed frame is installed and engaged with the top of the sliding frame through the mounting plates at both ends, and the positioning bolt is used for limiting operation, which is convenient and stable for fixed installation. The adjustable mounting plate is convenient for pulling and adjusting the length, and can adapt to the installation and fixing of sliding frames of different specifications. The detachable setting ensures that the equipment can be directly disassembled and put away when not lifted, reducing the soaking situation. By controlling the knob on the top of the equipment, the first bevel gear and the second bevel gear are driven to mesh and rotate when turned, which can stably drive the middle screw to be lifted and lowered through the thread.

[0022] The second bevel gear 8 forms a transmission structure through the first bevel gear 7 and the knob 6, and the screw rod 9 forms a lifting structure through the second bevel gear 8 and the fixed frame 2. The screw rod 9 can be adjusted to drive the bottom connecting frame 10 to descend to a suitable position for clamping and connecting the gate. The gate after clamping can also be controlled to be lifted and lowered, which is convenient for lifting control.

[0023] The locking mechanism 12 includes a threaded ring 1201, a transmission rod 1202, a buckle 1203 and a fixed shaft 1204. The transmission rod 1202 is rotatably installed on both sides of the threaded ring 1201. The end of the transmission rod 1202 is rotatably connected to the buckle 1203. The side of the buckle 1203 is connected to the fixed shaft 1204.

[0024] The buckle 1203 forms a rotating structure with the connecting frame 10 through the fixed shaft 1204, and the buckle 1203 forms a transmission structure with the transmission rod 1202, the threaded ring 1201 and the adjusting rod 11, so as to flexibly control the opening and closing of the buckle 1203 and facilitate the connection and separation operation with the gate.

[0025] The connecting frame 10 forms a snap-fit ​​structure with the clamping plate 13 through the buckle 1203, and the clamping plate 13 forms a lifting structure with the sliding frame 1 through the screw rod 9, thereby stably connecting the connecting frame 10 and the door body 14 to ensure that the door body 14 can be lifted and lowered.

[0026] Example 2

[0027] like Figure 1-3 As shown, this embodiment further illustrates Example 1, connecting rods 3 are provided on both sides of the fixing frame 2, the ends of the connecting rods 3 are connected to mounting plates 4, positioning bolts 5 are passed through the tops of both ends of the fixing frame 2, and the mounting plates 4 form a snap-fit ​​structure with the fixing frame 2 through the positioning bolts 5, and the mounting plates 4 form a sliding structure with the fixing frame 2 through the connecting rods 3, which can adapt to the installation and fixation of sliding frames 1 of different specifications, and the detachable setting ensures that the equipment can be directly disassembled and stored when not lifted, thereby reducing soaking.

[0028] Working principle: First, the fixed frame 2 is installed and engaged with the top of the sliding frame 1 through the mounting plates 4 at both ends, and the positioning operation is performed through the positioning bolts 5, which is convenient for stable fixed installation.
