Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, and in particular to a high-efficiency water conservancy gate opening and closing mechanism. Background Technology

[0002] The hydraulic gate opening and closing mechanism is designed to enable the rapid and precise opening and closing of hydraulic gates. It is widely used in various water conservancy projects, such as reservoirs, rivers, and irrigation systems, to effectively regulate water levels, control water flow, and ensure the safe operation of water conservancy facilities and the rational allocation of water resources.

[0003] In water conservancy projects, gate opening and closing mechanisms are key equipment for controlling water flow. However, existing water conservancy gate opening and closing mechanisms have some shortcomings, affecting the operational efficiency and safety of water conservancy projects.

[0004] 1. Slow opening and closing speed: Traditional opening and closing mechanisms mostly use simple screw or winch drive methods, which have low power transmission efficiency, resulting in slow gate opening and closing speed. In response to emergencies such as sudden floods, it is impossible to quickly adjust the gate opening to release floodwater or block water in time, which may cause flood overflow and other disasters. At the same time, the stability during the opening and closing process is poor.

[0005] 2. Low control precision: Some opening and closing mechanisms lack precise positioning and adjustment devices, making it difficult for operators to accurately control the opening degree of the gate. This can easily lead to inaccurate water level regulation and affect the rational allocation of water resources. In particular, in irrigation systems and urban water supply projects with high requirements for water level control, low control precision may lead to problems such as uneven irrigation or insufficient water supply. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a highly efficient hydraulic gate opening and closing mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency hydraulic gate opening and closing mechanism includes an outer frame, a valve plate slidably connected inside the outer frame, a traction frame fixedly connected to one side of the valve plate, a traction mechanism for moving and traction of the valve plate on one side of the traction frame, barrier plates slidably connected to both sides of the outer frame, two push rods rotatably connected between the two barrier plates on the same side, a push mechanism for pushing the barrier plates on one side of the outer frame, a guide mechanism for guiding the movement of the barrier plates on one side of the outer frame, a flow guide groove on one side of the outer frame, and a connecting frame fixedly connected to one side of the valve plate.

[0009] Preferably, the traction mechanism includes multiple traction ropes fixedly connected to one side of the traction frame, a traction rod fixedly connected to one side of the traction frame, a drive box provided on one side of the traction frame, two symmetrically arranged rotating shafts rotatably connected inside the drive box, gears fixedly connected to the side walls of the rotating shafts, and a toothed plate fixedly connected to one end of the traction rod, the toothed plate meshing with the gears.

[0010] Preferably, the rotating shaft has a take-up groove on its side wall, the traction rope is wound in the take-up groove, a motor is fixedly connected to one side of the drive box, and the output shaft of the motor is fixedly connected to the rotating shaft on one side.

[0011] Preferably, the propulsion mechanism includes a base plate disposed on one side of the outer frame, and a plurality of abutment rods are fixedly connected to one side of the base plate, with one end of each abutment rod abutting against a traction rod.

[0012] Preferably, a plurality of guide rods are fixedly connected to one side of the base plate, and the guide rods extend into the outer frame.

[0013] Preferably, the guiding mechanism includes multiple limiting grooves formed on both sides of the outer frame, and a limiting block is fixedly connected to one side of the barrier frame, the limiting block being slidably connected within the limiting groove.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. This utility model is equipped with a gear, toothed plate, take-up groove, traction rope and drive box. Through the meshing of the toothed plate and gear and the traction of multiple strands of traction rope, the valve plate can be ensured to move and react quickly while maintaining stability during the movement process. At the same time, with the guide groove, the valve plate can be opened after the outer frame is separated from the valve plate, which can reduce the water pressure resistance when the valve plate is opened and facilitate the opening feedback of the gate.

[0016] 2. This utility model is equipped with structures such as a barrier plate, a guide channel, a connecting frame, a pushing rod, and a stop rod. The barrier plate can provide a seal on both sides of the connection between the outer frame and the gate to avoid leakage. At the same time, the opening of the valve plate, the opening of the guide channel, and the gradual opening of the outer frame can realize multi-stage control, thereby improving the control accuracy.

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1-4 A high-efficiency hydraulic gate opening and closing mechanism includes an outer frame 1, a valve plate 2 slidably connected inside the outer frame 1, a traction frame 3 fixedly connected to one side of the valve plate 2, a traction mechanism for moving the valve plate 2 provided on one side of the traction frame 3, the traction mechanism including multiple traction ropes 4 fixedly connected to one side of the traction frame 3, a traction rod 5 fixedly connected to one side of the traction frame 3, a drive box 6 provided on one side of the traction frame 3, two symmetrically arranged rotating shafts 7 rotatably connected inside the drive box 6, a take-up groove 10 provided on the side wall of the rotating shaft 7, the traction rope 4 being wound in the take-up groove 10, a motor 20 fixedly connected to one side of the drive box 6, and the output shaft of the motor 20 fixedly connected to one side of the rotating shaft 7.

[0024] A gear 9 is fixedly connected to the side wall of the rotating shaft 7, and a toothed plate 8 is fixedly connected to one end of the traction rod 5. The toothed plate 8 meshes with the gear 9.

[0025] Both sides of the outer frame 1 are slidably connected with barrier plates 12. Two push rods 15 are provided between the two barrier plates 12 on the same side. The two push rods 15 are rotatably connected. One side of the outer frame 1 is provided with a push mechanism for pushing the barrier plates 12. The push mechanism includes a base plate 17 provided on one side of the outer frame 1. Multiple guide rods 19 are fixedly connected to one side of the base plate 17. Multiple abutment rods 18 are fixedly connected to one side of the guide rods 19 inside the outer frame 1. One end of the abutment rod 18 abuts against the traction rod 15.

[0026] One side of the outer frame 1 is provided with a guide mechanism for moving the barrier plate 12. The guide mechanism includes multiple limiting grooves 13 opened on both sides of the outer frame 1. A limiting block 14 is fixedly connected to one side of the barrier plate 12. The limiting block 14 is slidably connected in the limiting groove 13. A flow guide groove 16 is provided on one side of the outer frame 1. A connecting frame 11 is fixedly connected to one side of the valve plate 2.

[0027] When using this utility model, such as Figure 1-4 As shown, during use, the outer frame 1 and valve plate 2 are first assembled. At this time, valve plate 2 and connecting frame 11 are slidably connected to the outer frame 1. Simultaneously, as the outer frame 1 moves downward, the push rod 15 on it contacts and abuts the stop rod 18. As the outer frame 1 continues to move downward, the push rod 15 rotates and opens, and its end contacts the sliding stop plate 12, thus pushing the stop plate 12 forward. The contact between the stop plate 12 and the gate mounting point ensures the side sealing of the outer frame 1 during use. During this process, the base plate 17 and its guide rod 19 cooperate with the outer frame 1, simultaneously providing support for the outer frame 1. When it is necessary to open the gate, this… When the motor 20 is turned on, it drives the rotating shaft 7 on one side to rotate. The gear 9 on the shaft meshes with the toothed plate 8, which drives the traction rod 5 to move upward. At this time, the traction rod 5 drives the valve plate 2 to move. At this time, the take-up groove 10 on the rotating shaft 7 simultaneously winds the traction rope 4. With the traction of the traction rope 4, the stability of the valve plate 2 during the movement can be ensured. When the valve plate 2 moves to the opening of the guide groove 16, the initial opening and drainage can be achieved. At the same time, it provides pressure relief for the movement of the outer frame 1. As the valve plate 2 continues to move, when the connecting frame 11 abuts against the inside of the outer frame 1, the valve plate 2 drives the outer frame 1 to move upward, achieving a further opening state.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
