Description

Technical Field

[0001] This utility model relates to the field of diversion tunnel technology, and in particular to a diversion tunnel sealing gate water-stopping device. Background Technology

[0002] Primarily based on long-standing construction challenges in water conservancy projects, diversion tunnel sealing gates are key temporary or permanent facilities in water conservancy and hydropower projects, with their core functions revolving around controlling water flow, ensuring safety, and coordinating construction progress.

[0003] The existing blocking gate involves cleaning the bottom of the diversion tunnel and performing foundation treatment. According to the design requirements, steel piles are driven into the foundation to reinforce the ground. Concrete is poured into the diversion tunnel according to the concrete mix ratio requirements. After the concrete has solidified, the concrete gate is installed to ensure that the gate fits tightly with the tunnel opening. However, during operation, it is necessary to prevent water from being effectively blocked in the diversion tunnel, which could lead to water leakage and affect the subsequent work process.

[0004] Therefore, we propose a diversion tunnel sealing gate water-stopping device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water-stopping device for sealing diversion tunnel gates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water-stopping device for sealing a diversion tunnel gate includes a gate frame. A lifting device is installed on the upper surface of the gate frame. A fixed disc is fixedly installed inside the upper part of the lifting device. The fixed disc is sleeved on both ends of a ball screw. A sliding block is installed on the surface of the ball screw. A hinge is fixedly installed at the front end of the gate frame. A rotating rod is installed inside the hinge and is inserted into the end of a baffle plate through the rotating rod.

The two ends of the ball screw are sleeved inside the fixed disc, which drives the sliding block to move up and down. It also drives the gate to move up and down through the connecting support rod, which facilitates effective blocking and control of the diversion hole, prevents water leakage, and improves the efficiency of subsequent work processes.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A water-stopping device for sealing a diversion tunnel gate includes: a gate frame 1, a lifting device 2 installed on the upper surface of the gate frame 1 for effective control of the gate 28, facilitating effective up-and-down movement and water-stopping effect; a fixed disc 21 is fixedly installed inside the upper part of the lifting device 2, the fixed disc 21 is sleeved on both ends of a ball screw 22, allowing the ball screw 22 to rotate effectively using bearings installed inside the fixed disc 21, preventing jamming during rotation; a sliding block 23 is installed on the surface of the ball screw 22; a hinge 3 is fixedly installed at the front end of the gate frame 1, a rotating rod 31 is installed inside the hinge 3 and inserted into the end of a baffle plate 32 through the rotating rod 31, facilitating effective blocking of the water source, reducing the impact of the water source, and improving the water-stopping effect.

[0019] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the left and right sides of the lifting device 2 are provided with through grooves that are compatible with the support rod 24, so as to prevent the support rod 24 from rubbing against the edge of the lifting device 2 when it is raised or lowered.

[0020] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the surface of the sliding block 23 is provided with a screw hole that matches the ball screw 22 to prevent the sliding block 23 from rubbing against the surface of the ball screw 22 when it moves, thus preventing jamming. The surface diameter of the fixed disc 21 is larger than the surface diameter of the sliding block 23 to prevent it from detaching when it moves on the surface of the ball screw 22, thus avoiding the phenomenon of falling off. The surface of the sliding block 23 is connected to the inner wall of the gate 28 by a support rod 24, which facilitates the lifting and lowering of the two sets of gates 28.

[0021] Furthermore, refer to Figure 3 It can be seen that the upper end of the fixed disc 21 is fixedly connected to a threaded rod 26, which is inserted into the inside of the fixed block 25. A rotating handle 27 is installed on the surface of the threaded rod 26, and the rotating handle 27 is set in an arc shape to facilitate effective control for the work task that requires water to be stopped, and to prevent jamming.

[0022] Furthermore, refer to Figure 4 and Figure 5It can be seen that the hinge 3 is U-shaped, and a rotating rod 31 is installed inside the hinge 3 to facilitate effective control of the rotation of the blocking plate 32.

[0023] Furthermore, refer to Figure 5 It can be seen that the end of the baffle plate 32 is arc-shaped and has a hole. A rotating rod 31 is inserted into the hole to facilitate control of the baffle plate 32 and to effectively block the water source. A hole is opened on one side of the hinge 3 and a connecting rod 33 is inserted into the hole. A threaded fixing buckle 34 is fixedly installed at one end of the connecting rod 33 to facilitate effective control and fixation of the rotating rod 31 inside the hinge 3, preventing shaking or loosening when blocking the water source.

[0024] Working principle: When in use, the rotating handle 27 rotates on the surface of the threaded rod 26 and is effectively fixed by the fixing block 25. This drives the ball screw 22 inside the lifting device 2 to rotate effectively. The two ends of the ball screw 22 are sleeved inside the fixed disc 21. When the ball screw 22 rotates, it drives the sliding block 23 installed on the surface of the ball screw 22 to move, causing the gate 28 connected to the support rod 24 fixed on one side of the sliding block 23 to move up and down. At this time, rotating the threaded fixing buckle 34 clockwise connects the connecting rod 33 to one end of the rotating rod 31, causing the blocking plate 32 to rotate inside the hinge 3 and stand upright. Rotating the threaded fixing buckle 34 counterclockwise locks the rotating rod 31 inside the hinge 3, preventing the blocking plate 32 from shaking.

[0025] The above is the complete working principle of this utility model.
