Description

Technical Field

[0001] This utility model relates to the field of triangular gate technology, specifically a large triangular gate with online monitoring function. Background Technology

[0002] A triangular gate is a specially designed gate used in water conservancy projects to control the velocity and flow rate of water. Its triangular shape gives it a better structural load-bearing capacity compared to other types of gates, and it can effectively regulate the flow of fluids. This design is generally suitable for water conservancy projects that require high stability and water flow control, such as irrigation systems, hydropower stations, and drainage systems.

[0003] Currently, while existing large triangular gates can effectively block water during actual use, they need to withstand significant stress and external forces during this process. However, these gates lack online monitoring capabilities, making it impossible to monitor their operational status during use. To address this issue, we offer large triangular gates with online monitoring capabilities. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a large triangular gate with online monitoring function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large triangular gate with online monitoring function, comprising two dams, each dam having a top pivot and a bottom pivot fixedly connected to its inner wall, a monitoring mechanism shared inside the two dams, the monitoring mechanism comprising two rotating shafts, each rotating shaft having two connecting rods fixedly connected to its outer surface, each connecting rod having a gate plate fixedly connected to its end away from the rotating shaft, each gate plate having four support arms fixedly connected to its outer surface, each support arm having a strain gauge fixedly connected to its upper surface and the connecting rods having a triaxial acceleration sensor fixedly connected to its upper surface, the bottom pivot having its upper surface, and the top pivot having its bottom surface, each top pivot having two laser ranging sensors fixedly connected to its bottom surface, each top pivot having a bearing fixedly connected to its inner wall and the bottom pivot having a bearing, the inner ring of each bearing being fixedly connected to the outer surface of the rotating shaft.

[0006] Furthermore, two fixing plates are fixedly connected to the two opposite sides of the two dams, and several support columns are fixedly connected to the opposite side of each set of fixing plates.

[0007] Furthermore, each of the support columns is fixedly connected to an anti-slip pad on its outer surface, and each set of support arms is fixedly connected to a reinforcing column on its outer surface.

[0008] Furthermore, each set of fixed plates has a reinforcing block fixedly connected to the side of each other that is far apart, and the side of each set of reinforcing blocks that is close to each other is fixedly connected to the side of each of the two dams that is far apart.

[0009] Furthermore, each of the dams is provided with two fixing rings inside, and the inner wall of each fixing ring is fixedly connected to the outer surface of the rotating shaft.

[0010] Furthermore, each set of fixing rings has a fixing post fixedly connected to its outer surface, and the outer surface of each fixing post is fixedly connected to the outer surface of the support arm.

[0011] Compared with existing technologies, this large triangular gate with online monitoring function has the following advantages: This invention incorporates strain gauges on the upper surface of the gate arm and the outer surface of the connecting rod that links the rotating shaft to the gate. These gauges can simultaneously capture stress changes in the two key load-bearing components, the gate arm and the connecting rod, during the water-blocking process. Compared to traditional gates without monitoring capabilities, this invention can promptly detect risks such as stress concentration and sudden increases in abnormal stress, thus avoiding the problem of component fatigue damage caused by prolonged excessive stress going unnoticed.

[0012] This invention, by setting three-dimensional acceleration sensors on the upper surface of the support arm, the bottom surface of the top pivot, and the upper surface of the bottom pivot, can comprehensively monitor the vibration direction and intensity of the gate under the impact of water flow and external forces. By acquiring vibration data in real time, it can determine whether the gate is in a stable working state, prevent structural loosening and displacement caused by abnormal vibration, and make up for the shortcomings of traditional gates that cannot sense dynamic stress risks.

[0013] This invention, by incorporating a laser rangefinder sensor, can measure the distance between relevant components in real time. Combined with the stable support of the rotating shaft by the bearings on the inner walls of the top and bottom pivots, it can not only ensure the flexibility of the gate's rotation but also determine whether there is any abnormal displacement of the rotating shaft or the gate plate through the distance measurement data, thus further improving the monitoring dimensions of the overall working status of the gate.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] This embodiment provides a large triangular gate with online monitoring function. This device is used to monitor the working status during use.

[0018] See Figures 1-5 The large triangular gate with online monitoring function includes two dams 1. Each dam 1 has a top pivot 2 and a bottom pivot 3 fixedly connected to its inner wall. The two dams 1 are equipped with a monitoring mechanism 4. Two fixed plates 409 are fixedly connected to the side of the two dams 1 that are far apart from each other. Several support columns 410 are fixedly connected to the side of each set of fixed plates 409 that are close to each other. The fixed plates 409 and the support columns 410 can form a ladder structure, which makes it convenient for staff to climb up the dam 1 to inspect and maintain the equipment above.

[0019] The monitoring mechanism 4 includes two rotating shafts 401. Two connecting rods 404 are fixedly connected to the outer surface of each rotating shaft 401. Anti-slip pads 411 are fixedly connected to the outer surface of each support column 410. Reinforcing columns 413 are fixedly connected to the outer surface of each set of support arms 403. The anti-slip pads 411 are usually made of materials with high friction coefficient and wear resistance. Their function is to enhance the friction of the surface of the support column 410.

[0020] Each set of connecting rods 404 is fixedly connected to a gate plate 402 at the end away from the rotating shaft 401. Four support arms 403 are fixedly connected to the outer surface of each gate plate 402. Each set of fixed plates 409 is fixedly connected to a reinforcing block 412 on the side away from each other. The side of the two sets of reinforcing blocks 412 that are close to each other is fixedly connected to the side of the two dams 1 that are away from each other. The reinforcing block 412 is fixed to the fixed plate 409 and the dam 1 respectively, forming a triangular stable structure. This structure can greatly enhance the firmness of the connection between the fixed plate 409 and the dam 1. When the support column 410 supports the dam 1, the fixed plate 409 will be subjected to the reaction force transmitted by the support column 410. The reinforcing block 412 can effectively disperse these reaction forces.

[0021] Strain gauges 405 are fixedly connected to the upper surface of each support arm 403 and the outer surface of the connecting rod 404. Triaxial acceleration sensors 406 are fixedly connected to the upper surface of each support arm 403, the upper surface of the bottom pivot 3, and the bottom surface of the top pivot 2. Two fixing rings 415 are provided inside each dam 1. The inner wall of each fixing ring 415 is fixedly connected to the outer surface of the rotating shaft 401. The fixing ring 415 can provide a fixed connection platform, which facilitates the docking of the support arm 403 and the rotating shaft 401 to form a stable frame structure.

[0022] Two laser rangefinders 408 are fixedly connected to the bottom surface of each top pivot 2. Bearings 407 are fixedly connected to the inner wall of each top pivot 2 and the inner wall of each bottom pivot 3. The inner ring of each bearing 407 is fixedly connected to the outer surface of the rotating shaft 401. A fixing post 414 is fixedly connected to the outer surface of each set of fixing rings 415. The outer surface of each fixing post 414 is fixedly connected to the outer surface of the support arm 403. When the support arm 403 bears the force transmitted by the gate 402, in addition to the support arm 403 directly transmitting the force to the rotating shaft 401, part of the force can also be transmitted to the fixing ring 415 through the fixing post 414, and then transmitted to the rotating shaft 401 by the fixing ring 415. This can effectively disperse the force at the connection between the support arm 403 and the rotating shaft 401, reduce the force concentration at the connection, and reduce the risk of damage to the connection between the support arm 403 and the rotating shaft 401.

[0023] Working principle: In operation, the operator first connects the strain gauge 405, triaxial accelerometer 406, and laser rangefinder 408 to the power supply. Then, the strain gauge 405, triaxial accelerometer 406, and laser rangefinder 408 are turned on. The strain gauge 405 can monitor the stress changes of the support arm 403 and connecting rod 404 in real time. When the stress exceeds the preset safety range, an alarm will be issued promptly, reminding the operator to take appropriate measures. Stress monitoring involves arranging twelve surface strain gauges 405 at key locations such as the front and rear ends of the upper left, upper right, and lower right support arms 403, the top pivot 2, the bottom pivot 3, and the connecting rod 404 to measure structural stress changes in real time. The triaxial accelerometer 406 can monitor… The vibration of the gate under the impact of water flow, including the direction, intensity and frequency of the vibration, is used to determine whether the gate is in a stable state. The laser ranging sensor 408 measures the distance changes between the top pivot 2 and the bottom pivot 3, as well as between the rotating shaft 401 and the dam 1, to determine whether there is abnormal displacement of the gate, further ensuring the safe operation of the gate. Two laser ranging sensors 408 are symmetrically arranged at the end of the foundation support shaft of the top pivot 2. The wear or displacement of the bearing 407 is judged by the displacement change. The system integrates a multi-dimensional sensor network and real-time data acquisition and analysis to achieve comprehensive online monitoring of the stress, dynamic characteristics and operating status of the key structure of the triangular gate, ensuring the safe operation of the gate and the efficient utilization of water resources.
