[0002] Steel gates are water-retaining facilities in water conservancy projects made primarily of steel. They possess high strength, good toughness, and impact resistance, and can flexibly control the direction of water flow and regulate water levels. They are widely used in water conservancy projects such as reservoirs, rivers, and sluice gates.

[0003] A steel gate performance testing device is a device used to test various performance indicators of steel gates. It typically consists of sensors, data acquisition devices, and control devices. The sensors monitor parameters such as stress, deformation, and displacement of the steel gate under different working conditions in real time and transmit these data to the data acquisition device.

However, the paint coating may conceal or obscure defects such as weld seams, material cracks, or pores on the surface of the steel gate, leading to inaccurate test results and affecting the safety and service life of the steel gate. Therefore, a performance testing device for steel gates is proposed to solve the above problems. Utility Model Content

The gas passes through the gap and causes the swing bar at the bottom of the placement frame to swing. The camera and ultrasonic probe respectively detect the surface condition and paint thickness of the gate, thus realizing the comprehensive detection of the steel gate performance. Not only are the detection items comprehensive, covering surface flatness, gaps and paint thickness, but the operation is also simple and the components are closely matched, which greatly improves the detection efficiency and accuracy.

In this utility model, rotating the knob drives the driven stage to rotate, and then the wedge block one on the right side of the driven stage presses against the wedge block two, causing the fixing block to slide in the fixing groove and lock into the inner wall of the gate. Then, by inserting the positioning pin, the driven stage is limited and fixed. First, the positioning pin is pulled out, and then the driven stage is reset by the elastic reset of the spring two and the connecting block. The elastic action of the spring one drives the fixing block to reset. Thus, the gate can be quickly and firmly fixed by the cooperation of the knob, wedge block and other components, providing a reliable foundation for detection, facilitating disassembly and subsequent use, and improving the practicality and efficiency of the detection device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a performance testing device for a steel gate, comprising a carrier 1, a fixing plate 2 fixedly connected to the front side of the carrier 1, a testing mechanism 3 fixedly connected to the inner wall of the front side of the fixing plate 2, and fixing mechanisms 4 rotatably connected to the left and right sides of the carrier 1. The testing mechanism 3 includes a motor 301, which is the power source for the testing mechanism 3. The front side of the motor 301 is fixedly connected to the inner wall of the front side of the fixing plate 2, and the fixing plate 2 provides fixation and support for the motor 301. A rotating table 302 is fixedly connected to the drive end of the motor 301, and the rotating table 302 receives power from the motor 301. The rotating platform 302 is rotated by the force of the rotating platform 302. The rotating plate 303 is rotatably connected to the rear side of the rotating platform 302. The rotating plate 303 receives the force from the rotating platform 302 and rotates synchronously. The fixed plate 2 has two carrier plates 304 slidably connected inside. The carrier plate 304 provides support for the linkage frame 305 and receives the force from the linkage frame 305 to slide. The front side of one of the carrier plates 304 is slidably connected to the linkage frame 305. The linkage frame 305 is used to receive the force from the rotating plate 303 to move synchronously, thereby driving the carrier plate 304 to slide synchronously. The carrier 1 is equipped with a gap detection component 306.

[0042] Specifically, the steel gate performance testing device consists of a carrier 1, a fixed plate 2, a testing mechanism 3 and a fixing mechanism 4. The testing mechanism 3 uses a motor 301 as a power source, and drives the carrier plate 304 to slide through a rotating table 302, a rotating plate 303 and a linkage frame 305. The carrier 1 is also equipped with a gap detection component 306.

[0043] Reference Figure 2 and Figure 5Two cameras 307 are fixedly connected to the front inner wall of the fixing plate 2. The cameras 307 can detect the surface condition of the gate plate 5. An ultrasonic probe 308 is fixedly connected to the front inner wall of the fixing plate 2. The ultrasonic probe 308 can detect the thickness of the paint sprayed on the surface of the gate plate 5. Multiple rollers 309 are rotatably connected to the rear side of the carrier plate 304. The rollers 309 can receive the force from the carrier plate 304 and move synchronously to detect the surface of the gate plate 5 to detect whether it is uneven. The gap detection component 306 includes a placement frame 30601. The placement frame 30601 provides fixation and support for the gap detection component 306. The placement rack 30601 is installed inside the carrier 1. The placement rack 30601 can be manually moved, placed, or removed during use. The bottom of the placement rack 30601 is rotatably connected to multiple swing bars 30602. The swing bars 30602 can receive gas passing through the gap of the gate 5 and swing synchronously to detect whether there is a gap in the gate 5. Multiple airbags 30603 are fixedly connected to the inner wall of the left side of the fixed plate 2. The airbags 30603 can be squeezed by the carrier plate 304 and then suck in air from the outside, thereby filling the cavity between the fixed plate 2 and the gate 5 with air to detect whether there is a gap in the gate 5.

[0044] Specifically, a camera 307 is connected to the inner wall of the front side of the fixed plate 2 to detect the surface condition of the gate plate 5, an ultrasonic probe 308 measures the paint thickness, a roller 309 on the rear side of the carrier plate 304 detects the surface flatness, and an airbag 30603 is filled with air in the gap detection component 306. If there is a gap in the gate plate 5, the air causes the swing bar 30602 to swing for detection.

[0045] Reference Figures 1 to 3 The fixing mechanism 4 includes a knob 401. By rotating the knob 401, the operator's manual rotational force can be transmitted to the driven platform 402. The two knobs 401 are rotatably connected to the left and right sides of the carrier 1, respectively. The driven platform 402 is fixedly connected to the right side of one of the knobs 401. The driven platform 402 receives the force from the knob 401, which in turn drives the first wedge block 403 to rotate synchronously. Two wedge blocks 403 are fixedly connected to the right side of the driven platform 402. The first wedge block 403 receives the force from the driven platform 402 and rotates, which in turn can squeeze the second wedge block 408. The internal part of the platform 402 is provided with a positioning pin 404, which is used to fix the driven platform 402 when it is rotated to a suitable position by inserting the positioning pin 404. The internal part of the carrier 1 is provided with multiple fixing slots 405. The fixing slots 405 provide limiting and guiding functions for the fixing block 406. The fixing block 406 is slidably connected inside one of the fixing slots 405. The fixing block 406 is used to snap into the inside of the gate 5 to fix it. The left side of the fixing block 406 is fixedly connected with a spring 407. The spring 407 has an elastic function and provides fixing and support for the fixing block 406.

[0046] Specifically, the fixing mechanism 4 includes a knob 401, which is rotatably connected to both sides of the carrier 1. Rotating the knob 401 drives the driven platform 402, which in turn causes the first wedge block 403 to rotate and squeeze the second wedge block 408, causing the fixing block 406 to slide into the fixing groove 405 and be fixed in the gate 5. The positioning pin 404 assists in fixing, and the first spring 407 provides support.

[0047] A wedge block 408 is slidably connected to the left side of the fixed block 406. The wedge block 408 is used to be squeezed by the wedge block 403, which in turn drives the fixed block 406 to move and fix its gate 5. Two reset components 409 are opened inside the carrier 1. The reset component 409 includes a limiting groove 40901. The limiting groove 40901 provides a fixing and support function for the spring 40902. The limiting groove 40901 is opened inside the carrier 1, and the carrier 1 provides space for the limiting groove 40901. The spring 40902 is fixedly connected to the bottom inner wall of the limiting groove 40901. The spring 40902 has an elastic function and provides elastic support for its connecting block 40903. After the force is applied, the connecting block 40903 can be pulled to reset by its own elastic function. The connecting block 40903 is fixedly connected to the top of the spring 40902. The connecting block 40903 is used to limit the driven stage 402.

[0048] Specifically, the left side of the fixed block 406 is slidably connected to the second wedge block 408. After being squeezed by the first wedge block 403, the fixed block 406 moves to fix the gate 5. There are two reset components 409 in the carrier 1, which are composed of a limiting groove 40901, a second spring 40902 and a connecting block 40903. The second spring 40902 provides elastic support, and the connecting block 40903 limits the driven stage 402.

[0049] Reference Figure 2 , Figure 4 and Figure 5The right side of the rotating plate 303 is rotatably connected to the inside of the linkage frame 305. The inside of the linkage frame 305 receives force from the rotating plate 303, which in turn drives the carrier plate 304 to slide. The left side of one of the carrier plates 304 contacts the right side of multiple airbags 30603. When the carrier plate 304 slides back and forth, it can compress the airbags 30603, thereby inflating the cavity between the fixed plate 2 and the gate plate 5 to detect gaps. The inside of the carrier 1 is provided with a gate plate 5, which is used for testing after painting. The front side of the gate plate 5 contacts the rear side of multiple rollers 309. The rollers 309 receive force from the carrier plate 304 and slide to test the surface of the gate plate 5. Two wedges The adjacent side of the first wedge block 403 contacts the distant side of the two second wedge blocks 408. When the first wedge block 403 rotates, it can squeeze the second wedge block 408, which in turn drives the fixing block 406 to slide and fix the gate 5. The outside of the fixing block 406 contacts the inner wall of the gate 5. The fixing block 406 is used to fix the gate 5 and prepare for subsequent testing. The outside of the connecting block 40903 is slidably connected to the inside of the limiting groove 40901. The limiting groove 40901 provides the limiting and guiding function for the connecting block 40903. The left side of the connecting block 40903 is fixedly connected to the right side of the driven stage 402. The driven stage 402 provides the limiting and guiding function for the connecting block 40903.

[0050] Specifically, the right side of the rotating plate 303 is rotatably connected to the linkage frame 305, which drives the carrier plate 304 to slide. The carrier plate 304 squeezes the airbag 30603 to inflate and detect the gap. The roller 309 slides with the carrier plate 304 to detect the surface of the gate plate 5. The first wedge block 403 squeezes the second wedge block 408 to drive the fixing block 406 to fix the gate plate 5. The connecting block 40903 slides in the limiting groove 40901 and is connected to the driven stage 402.

[0051] Working principle: When it is necessary to test the gate plate 5 after painting, the motor 301 drives the rotating table 302 to rotate. Then, through the connection between the rotating plate 303 and the linkage frame 305, the carrier plate 304 is driven to slide back and forth. Then, the rollers 309 on the carrier plate 304 can slide on the surface of the gate plate 5. During the sliding process, the surface is checked for unevenness. At the same time, one of the carrier plates 304 can squeeze the air bag 30603 when sliding, injecting air into the cavity between the fixed plate 2 and the gate plate 5. If there is a gap in the gate plate 5, the gas passes through the gap and causes the swing bar 30602 at the bottom of the placement frame 30601 to swing, realizing gap detection. The camera 307 and the ultrasonic probe 308 respectively detect the surface condition and paint thickness of the gate plate 5, achieving the purpose of comprehensive testing of the performance of the gate plate 5.

[0052] When it is necessary to fix the gate plate 5, the driven stage 402 is rotated by rotating the knob 401. Then, the wedge block 403 on the right side of the driven stage 402 presses the wedge block 408, causing the fixing block 406 to slide in the fixing groove 405 and be inserted into the inner wall of the gate plate 5, thereby fixing the gate plate 5. Then, the driven stage 402 is limited and fixed by inserting the positioning pin 404. After the test is completed, the positioning pin 404 is pulled out first. Then, the driven stage 402 is reset by the elastic reset of the spring 40902 and the connecting block 40903. The fixing block 406 is reset by the elastic action of the spring 407, thereby stabilizing and fixing the gate plate 5 and providing a foundation for the test.
