[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0019] This application provides a quick-release device for the push-pull rod plug of a water turbine relay.

[0020] A square plug 3 is clamped between two clamping housings 1. The square plug 3 is used to connect to the turbine servo. One end of the square plug 3 is machined with a connecting groove for connecting to the turbine servo. Two clamping housings 1 are arranged vertically parallel and spaced apart, and each of the two clamping housings has a clamping groove 101 for clamping the workpiece on its opposite surface. The limiting mechanism 4 is mainly composed of a positioning component 401 and a support component 402, wherein the positioning component 401 is detachably connected to the support component 402. The positioning component 401 includes a first positioning cylinder 4011 with a smaller diameter and a second positioning cylinder 4012 with a larger diameter, and a connecting rod 4014 is rotatably connected between the two. The support component 402 includes a semi-circular frame 4021 and a mounting block 4024 slidably mounted on the semi-circular frame. The connecting rod 4014 and the mounting block 4024 are detachably connected. The connecting rod 4014 and the mounting block 4024 are designed to be detachably connected, facilitating the positioning of the first positioning cylinder 4011 and the second positioning cylinder 4012, and ensuring accurate connection between the square plug 3 and the turbine relay during connection, avoiding repeated adjustments. Furthermore, a first rotating mechanism 8 is provided on both sides of the two clamping housings 1, and a second rotating mechanism 9 is provided between the two first rotating mechanisms 8. Through the coordinated operation of the first rotating mechanism 8 and the second rotating mechanism 9, the spatial installation position and orientation of the clamping housing 1 can be flexibly and precisely adjusted, thereby meeting the needs of multi-angle clamping operations.

[0021] A threaded groove 102 is provided on the opposite side of one side of the clamping housing 1, and a fixing plate 103 is fixedly provided on its side. Each fixing plate 103 has a threaded hole. A first fixing bolt 104 is provided between the two vertically opposite clamping housings 1. The first fixing bolt 104 cooperates with the threaded hole to bring the two clamping housings 1 closer together, thereby firmly clamping and fixing the plug 3 located between them, ensuring that the plug will not loosen or shift during operation.

[0022] The positioning assembly 401 also includes a connecting cylinder 4013, whose two ends are firmly fixed between the first positioning cylinder 4011 and the second positioning cylinder 4012, respectively, serving as a structural connection and support. The connecting cylinder 4013 and the connecting rod 4014 are rotatably connected, allowing the connecting cylinder to rotate flexibly around the connecting rod, thereby driving the first and second positioning cylinders to rotate synchronously, achieving angle adjustment and improving the overall structure's flexibility and applicability. This facilitates the positioning of the first and second positioning cylinders 4011 and 4012, ensuring that the clamping housing 1 and the plug 3 are connected on the same axis. After the clamping housing 1 and the plug 3 are aligned on the same axis, the positioning assembly 401 is removed, and the plug 3 is rotatably connected to the clamping housing 1.

[0023] The support assembly 402 also includes a bracket 4022 and a slider 4025. The bracket 4022 is spaced apart within the semi-circular frame 4021, and the semi-circular frame 4021 is detachably connected to the clamping housing 1. A sliding hole 4023 is provided on the bracket 4022, and the sliders 4025, fixedly connected to both sides of the mounting block 4024, pass through the sliding hole 4023, thereby enabling the mounting block 4024 to slide along the bracket 4022, facilitating flexible adjustment of the installation position. The mounting block 4024 is designed to be slidable, providing operational space when removing the first positioning cylinder 4011 and the second positioning cylinder 4012. Furthermore, the positioning assembly 401 and the support assembly 402 are detachably connected to the clamping housing 1; when positioning the clamping housing 1 and the plug 3 is required, the positioning assembly 401 and the support assembly 402 can be used.

[0024] Multiple springs 4026 are provided at both the upper and lower ends of the mounting block 4024 to provide cushioning or reset functions. A connecting shaft 4027 is rotatably connected to the mounting block 4024, and the connecting rod 4014 is detachably connected to the mounting block 4024 by a second fixing bolt 4028. The second fixing bolt 4028 passes through the connecting shaft 4027, which ensures the stability of the connection and allows the connecting rod to rotate flexibly around the connecting shaft.

[0025] A screw 2 is threaded through the first rotating mechanism 8, with one end of the screw 2 threaded into the threaded groove 102 on the clamping housing 1. By tightening the screw 2, it can be pressed against the fixed surface, thereby locking the rotation of the first rotating mechanism 8 and ensuring a stable clamping posture. A handle 201 is fixedly connected to the upper end of the screw 2, facilitating manual force application by the operator to achieve quick locking and unlocking. The first rotating mechanism 8 can be lifted by the lifting ring 803 to adjust the connection and positioning of the clamping housing 1 and the plug 3. If any problems are found after the first rotating mechanism 8 has been adjusted, the second rotating mechanism 9 can be rotated to adjust the connection between the clamping housing 1 and the plug 3.

[0026] First fixing bodies 5 are securely fixed at the corners of both clamping housings 1. Simultaneously, second fixing bodies 6 are also provided at the corners of the clamping housings 1, cleverly positioned between the two first fixing bodies 5. Each first fixing body 5 has an arc-shaped mounting groove 501, within which a first roller 502 is rotatably mounted to achieve flexible rolling support. Furthermore, multiple ball bearings 503 are spaced apart on both sides of the first fixing bodies 5, further enhancing the smoothness and flexibility of the overall structure.

[0027] The first rotating mechanism 8 mainly includes a circular frame 801, which has an annular groove 802 inside. During installation, the bottom surface of the annular groove 802 is in close contact with the first roller 502, and its sidewall is in close contact with the ball bearing 503, thus forming a stable and smooth rolling support structure. In addition, two lifting rings 803 are provided at intervals on each circular frame 801 to facilitate the lifting, handling, and position adjustment of the equipment, improving the overall ease of use. Multiple through holes are machined at equal intervals on one of the circular frames 801 to allow the screw 2 to pass through and be threaded into the threaded groove 102 machined on the clamping housing 1.

[0028] The second rotating mechanism 9 mainly includes two spaced-apart arc-shaped frames 901, which are connected by multiple connecting rods 905 to enhance the stability of the overall structure. Each arc-shaped frame 901 has an arc-shaped groove 902 inside, within which are multiple flexibly rotatable second rollers 904. A rolling cylinder 7 is mounted on each second roller 904, and the inner wall of the rolling cylinder 7 is fixedly connected to the second fixed body 6 on the clamping housing 1. Furthermore, lifting holes 903 are provided at both ends of the arc-shaped frame 901 to facilitate the overall lifting and positioning of the equipment.

[0029] A base 10 is stably mounted on the bottom surface of the arc-shaped frame 901, and the extended end of the cylinder 12 is fixedly connected to the bottom surface of the base 10. Simultaneously, a support frame 11 is also provided on the bottom surface of the base 10, and the other end of the cylinder 12 is connected to this support frame 11. Through the extension and retraction of the cylinder 12, the base 10 and the arc-shaped frame 901 above it can be smoothly raised and lowered, thereby achieving adaptive height adjustment of the overall structure. The support frame 11 mainly serves to support the second rotating mechanism 9.

[0030] The implementation principle of this embodiment is as follows: The device achieves stable clamping and flexible adjustment of the plug 3 through the coordinated operation of the clamping housing 1 and the limiting mechanism 4. First, the two vertical clamping housings 1 are brought closer together by the first fixing bolt 104 to clamp the plug 3, making it easier for the plug 3 to be inserted into the clamping housing 1. The clamping housing 1 only needs to leave enough gap for the plug 3 to be inserted. In terms of height adjustment, the cylinder 12 on the support frame 11 extends and retracts, driving the base 10 and the arc frame 901 to rise and fall smoothly, thereby driving the overall structure to make height adaptive adjustments. In terms of rotation adjustment, the circular frame 801 of the first rotation mechanism 8 cooperates with the first roller 502 and the ball 503 through the annular groove 802 to achieve smooth rotation support; the arc frame 901 of the second rotation mechanism 9 is provided with a second roller 904 and a rolling cylinder 7 to further ensure the flexibility of rotation. After the adjustment is in place, tightening the screw 2 to press against the fixing surface can lock the first rotation mechanism 8 and ensure the stability of the clamping posture. In addition, the connecting cylinder 4013 in the positioning assembly 401 is rotatably connected to the connecting rod 4014, and works with the spring 4026 on the mounting block 4024 for buffering and the slider 4025 for guiding, so that the overall structure has both flexibility and stability.
