Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and more particularly to a water conservancy gate for water conservancy projects which is easy to adjust. Background Art

[0002] In the water conservancy engineering system, water conservancy gates are the core components for regulating water flow and are widely used in water conservancy facilities such as reservoirs, rivers, and channels. They are related to the realization of important functions such as flood control, irrigation, power generation, and shipping.

[0003] Hydraulic gates generally control the flow of water by driving the gate plate to move and changing the area of ​​the water passage. However, there are many inconveniences in opening and closing to control the flow of water.

[0004] On the one hand, it is difficult to achieve fine adjustment of the degree of gate opening and closing. For example, in small irrigation channels, it is necessary to accurately control the tiny water flow to meet the water needs of crops in different areas, but the existing gate opening and closing operations can often only achieve a rough water flow adjustment, resulting in uneven distribution of water resources.

[0005] On the other hand, the complexity of the water flow itself also increases the difficulty of control. The velocity and pressure of the water flow vary greatly in different seasons and under different working conditions, and the impact force on the gate is different, making it difficult to accurately control the position of the gate and stably control the size of the water flow during the opening and closing process. In addition, some large gates have large structures, large inertia, and slow start and stop processes, which further affects the rapid and accurate control of the size of the water flow. At a time when water resources need to be flexibly allocated, improvements and optimizations are urgently needed to improve the operating efficiency of water conservancy projects. In view of this, we propose a water conservancy gate for water conservancy projects that is easy to adjust. Summary of the invention

[0029] Among them, the fixing mechanism includes receiving grooves 10 respectively opened inside the two sides of the connecting member 7, and the slot 9 is located between the receiving grooves 10, the inner walls of the receiving grooves 10 are respectively opened with a plurality of column grooves 11 connected with the inside of the slot 9, the outer wall of the plug 8 is opened with a head groove 12 penetrating it and corresponding to the column groove 11, the inner end walls of the receiving grooves 10 are rotatably connected with threaded rods 13, the inner walls of the receiving grooves 10 are slidably connected with push rods 14 threadedly connected with the threaded rods 13, the push rods 14 are staggered, and the opposite ends of the push rods 14 are arc-shaped structures, a plurality of rivet columns 15 corresponding to the column grooves 11 are arranged inside the receiving grooves 10, and an adjustment component for cooperating with the push rods 14 and adjusting the position of the rivet columns 15 is arranged in the receiving grooves 10.

[0030] The adjustment assembly includes multiple pairs of guide rods 16 fixedly connected to the inner wall of the storage groove 10, and the outer wall of the guide rod 16 is slidably connected with a guide plate 17. The outer wall of the guide rod 16 is sleeved with a tension spring 18, and the two ends of the tension spring 18 are respectively fixedly connected to the outer wall of the guide plate 17 and the inner wall of the storage groove 10, and the side of the guide plate 17 away from the tension spring 18 is fixedly connected to the end of the rivet column 15.

[0031] Specifically, when it is necessary to adjust the position of the door panel 3 to adjust the water flow, the threaded rod 13 is rotated to drive the push rod 14 to slide on the inner wall of the storage groove 10, so that the push rod 14 pushes the guide plate 17 in turn during the sliding process, so that the guide plate 17 moves and pulls the tension spring 18 to extend, and the guide plate 17 will drive the rivet column 15 to move together during the movement. The rivet column 15 will be inserted into the column groove 11 and the head groove 12 in turn during the movement, so as to connect the plug 8 and the connecting piece 7 together; by controlling the moving distance of the push rod 14, the number of connections between the plug 8 and the connecting piece 7 can be controlled, thereby controlling the number of door panels 3 that are moved upward by the connecting piece 7, and the winch 6 runs through its own wire rope to drag the connecting piece 7 upward, so that

[0032] The connecting member 7 drives the door panel 3 to move upward, so that water can flow through the door panels 3, and the door panels 3 fit together, and are limited and sealed by the slide groove 4 and the seal 5, so as to achieve convenient, fast and accurate adjustment of the water flow size.

[0033] The end of the seal 5 away from the door panel 3 extends in an arc shape to both sides, and the cross section of the seal 5 after extension forms a mushroom shape, and the inner wall of the slide groove 4 corresponds to the outer wall of the seal 5 after extension. The end of the seal 5 away from the door panel 3 extends in an arc shape to both sides, and the cross section of the seal 5 after extension forms a mushroom shape, which increases the contact area when the seal 5 fits with the corresponding slide groove 4, and this shape can effectively disperse the pressure of water and reduce local stress concentration.

The motor 22 can be used to conveniently control the rotation of the threaded rod 13. Since the directions of the threaded rod 13 are the same when the motor 22 rotates, the threads on the threaded rod 13 are set in opposite directions, thereby controlling the relative movement of the two push rods 14, thereby ensuring that the push rod 14 pushes the guide plate 17 to move.

[0037] The top of the connector 7 is fixedly connected with a protective cover 23, and the protective cover 23 covers the motor 22. Specifically, the motor 22 is covered by the protective cover 23, so as to protect the motor 22, thereby preventing water vapor and foreign matter from affecting the motor 22.

[0038] Working principle: when it is necessary to adjust the position of the door panel 3 to adjust the water flow, the threaded rod 13 is rotated to drive the push rod 14 to slide on the inner wall of the storage groove 10, so that the push rod 14 pushes the guide plate 17 in turn during the sliding process, so that the guide plate 17 moves and pulls the tension spring 18 to extend, and the guide plate 17 will drive the rivet column 15 to move together during the movement. The rivet column 15 will be inserted into the column groove 11 and the head groove 12 in turn during the movement, so as to connect the plug 8 with the connector 7 together; by controlling the distance moved by the push rod 14, the number of connections between the plug 8 and the connector 7 can be controlled, so as to control the number of door panels 3 moved by the upward movement of the connector 7, and the winch 6 runs through its own wire rope to drag the connector 7 upward, so that the connector 7 drives the door panel 3 to move upward so that the water flow can flow through between the door panels 3, and the door panels 3 fit each other, and are limited and sealed by the slide groove 4 and the seal 5, so as to achieve convenient, fast and accurate adjustment of the water flow.
