[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention facilitates the adjustment of the arc formed on the top of the first support frame and the second support frame by arranging the coordination of structures such as the inclined groove and the sliding rod. By enabling the device to simulate roofs of different shapes and specifications and to detect the strength of the dimming film on different roofs, the strength performance of the dimming film in various practical application scenarios can be comprehensively detected. Since roofs of different shapes and specifications have different effects on the stress distribution of the dimming film, this comprehensive simulation test can cover various stress conditions that the dimming film may encounter, thereby accurately evaluating its strength performance and providing accurate data support for the application of the dimming film in different types of roofs.

[0018] The present invention facilitates the device to simulate the states of the dimming shed film at different positions of the shed by setting the cooperation of the lifting plate and the first support frame. When the dimming shed film is in a stretched state, the pressure sensor arranged in the pressure plate can be used to test the strength of the dimming shed film in the stretched state by moving the pressure plate downward. When the strength of the dimming shed film in the shed roof state needs to be tested, the semicircular frame formed by the first support frame and the second support frame is only needed to support the dimming shed film into a semicircular shape from the bottom of the dimming shed film. In this process, the turntable needs to rotate to release a part of the wound dimming shed film so that it can be supported. Then, the pressure plate is moved downward to detect the strength of the dimming shed film in the semicircular state of the shed roof.

[0019] The present invention improves the clamping stability by arranging the cooperation of the second buffer plate and the convex block and other structures. The dimming shed film is clamped by the two second buffer plates, and the spring and air in the cavity of the clamping plate are squeezed. When the dimming shed film is subjected to impact force, the clamped part of the dimming shed film can be buffered by air pressure and elastic force, thereby avoiding the instability of the shed film and the interference to the detection equipment caused by the impact force. The detection process can be carried out more smoothly and accurately, and it can prevent the situation that the clamped part and the non-clamped part are easily torn due to the large impact force. The situation occurs, reducing the impact on the test results, and the staggered convex blocks arranged on the second buffer plate can increase the friction between the second buffer plate and the dimming shed film, improve the clamping strength and clamping stability, and make the turntable rotate to wind the excess part of the dimming shed film on the surfaces of the two clamping plates, and make the part of the dimming shed film above the outlet straighten, and squeeze the first buffer plate, and buffer the bent part of the dimming shed film by elastic force and air pressure, so as to avoid the contact between the dimming shed film and the inner wall of the outlet, which causes the dimming shed film to rupture due to the large stress at the bending position during strength testing;

[0020] The present invention facilitates the winding of the dimming shed film by setting up the coordination of structures such as the clamping plate and the turntable. When the two ends of the dimming shed film are clamped and fixed, the first motor rotates the turntable to wind the excess part of the dimming shed film on the surface of the two clamping plates, and the part of the dimming shed film above the outlet is straightened, and detection can be carried out. The two turntables rotate in coordination to drive the straightened part of the dimming shed film to be removed and wound, so that the previously wound part is moved out from the inside of the gathering shell, and this part of the area can be detected. In this way, comprehensive detection of the dimming shed film can be achieved, and different states of detection can be performed on different areas on the same dimming shed film.

Since roofs of different shapes and specifications have different effects on the stress distribution of the dimming film, this comprehensive simulation test can cover various stress conditions that the dimming film may encounter, so as to accurately evaluate its strength performance and provide accurate data support for the application of the dimming film in different types of roofs;

[0039] By setting up the cooperation of the lifting plate 210 and the first support frame 206 and other structures, it is convenient for the device to simulate the state of the dimming shed film at different positions in the greenhouse. When the dimming shed film is in a stretched state, the second hydraulic rod 306 is moved downward by the second hydraulic cylinder 307, and the pressing plate 305 is driven downward to squeeze the stretched dimming shed film. The strength of the dimming shed film in the stretched state can be tested by the pressure sensor set in the pressing plate 305. When it is necessary to test the strength of the dimming shed film in the roof state, it is only necessary to move the first hydraulic rod 201 upward by the first hydraulic cylinder 202, and drive the first support frame 206 upward by the lifting plate 210, so that the semicircular frame formed by the first support frame 206 and the second support frame 207 can support the dimming shed film into a semicircle from the bottom of the dimming shed film. In this process, the turntable 409 needs to rotate to release a part of the wound dimming shed film so that it can be supported, and then the pressing plate 305 is moved downward to detect the strength of the dimming shed film in the semicircular state of the roof.

[0040] like Figures 2 to 7 As shown, the detection mechanism 3 includes a base 301, a detection frame 302 is fixedly connected to the side of the base 301, a slide rail 303 is arranged on the top of the detection frame 302, a slider 304 is slidably connected inside the slide rail 303, a second hydraulic cylinder 307 is fixedly connected to the top of the slider 304, a second hydraulic rod 306 is slidably connected inside the second hydraulic cylinder 307, and a pressure plate 305 is fixedly connected to the bottom of the second hydraulic rod 306.

[0041] The lower end of the second hydraulic rod 306 passes through the slider 304 and extends below the slider 304. The pressure plate 305 is located below the slider 304. The first hydraulic cylinder 202 is fixedly connected to the inner wall of the base 301. The lifting plate 210 is located above the base 301. The connecting frame 204 is located between the lifting plate 210 and the pressure plate 305.

[0042] The convergence mechanism 4 includes two convergence shells 401, the top of the convergence shell 401 is provided with an outlet 402, the interior of the convergence shell 401 is provided with a convergence cabin 403, the interior of the convergence shell 401 is evenly provided with a plurality of cavities 404, the interior of the cavity 404 is fixedly connected with a piston rod 406, the piston rod 406 is elastically connected to the inner wall of the spring 405 through the cavity 404, the end of the piston rod 406 away from the spring 405 is fixedly connected to the first buffer plate 407, and the back of the convergence shell 401 is fixedly connected with the first Motor 408, a turntable 409 is rotatably connected to the first motor 408, a third slide groove 410 is provided inside the turntable 409, a second motor 411 is fixedly connected inside the turntable 409, a bidirectional screw rod 412 is rotatably connected to the second motor 411, two clamps 413 are threadedly connected to the bidirectional screw rod 412, a plurality of cavities 404 are evenly provided inside the clamps 413, a second buffer plate 414 is slidably connected to the clamps 413, and a plurality of protrusions 415 are fixedly connected to one end of the second buffer plate 414 away from the clamps 413.

[0043] The first buffer plate 407 is slidingly connected to the outlet 402, and the end of the second buffer plate 414 close to the clamping plate 413 is elastically connected to the cavity 404 on the clamping plate 413 through the piston rod 406 and the spring 405. The lifting plate 210 is located between the two convergence shells 401. There are two second buffer plates 414, and the several protrusions 415 on the two second buffer plates 414 are staggered. The turntable 409 is rotationally connected to the inner wall of the convergence cabin 403, the bidirectional screw rod 412 is rotationally connected to the third slide groove 410, and the second motor 411 is located on the side of the third slide groove 410.

[0044] The above scheme is adopted: by setting the cooperation of the second buffer plate 414 and the protrusion 415 and other structures, the stability of the clamping is improved, and the two ends of the dimming shed film are moved to between the two second buffer plates 414 inside the two focusing shells 401 through the two outlets 402 respectively, and then the second motor 411 is started to rotate the bidirectional screw rod 412. The rotation of the bidirectional screw rod 412 will drive the two clamping plates 413 to move towards each other through the bidirectional thread, and the dimming shed film is clamped by the two second buffer plates 414, and the spring 405 and air inside the cavity 404 on the clamping plate 413 are squeezed. When the dimming shed film is subjected to impact force, the clamped part of the dimming shed film can be buffered by air pressure and elastic force, so as to avoid the instability of the shed film and the interference to the detection equipment caused by the impact force, and the detection process can be more The clamping process can be carried out smoothly and accurately, and the tearing between the clamped part and the unclamped part due to the large impact force can be prevented, thereby reducing the influence on the test result. The staggered protrusions 415 arranged on the second buffer plate 414 can increase the friction between the second buffer plate 414 and the dimming shed film, thereby improving the clamping strength and the clamping stability. Subsequently, the first motor 408 is started to rotate the turntable 409, and the excess part of the dimming shed film is wound on the surfaces of the two clamping plates 413, and the part of the dimming shed film above the outlet 402 is straightened, and the first buffer plate 407 is squeezed, and the bent part of the dimming shed film is buffered by elastic force and air pressure, thereby avoiding contact between the dimming shed film and the inner wall of the outlet 402, which causes the dimming shed film to rupture due to the large stress at the bending position during the strength test.

[0045] By setting up the coordination of structures such as the clamping plate 413 and the turntable 409, it is convenient to wind up the dimming shed film. After the two ends of the dimming shed film are clamped and fixed, the first motor 408 rotates the turntable 409 to wind up the excess part of the dimming shed film on the surface of the two clamping plates 413, and straighten the part of the dimming shed film above the outlet 402, so that detection can be carried out. By the coordinated rotation of the two turntables 409, the straightened part of the dimming shed film is driven to move away and wind up, so that the previously wound part is moved out from the inside of the gathering shell 401, and this part of the area can be detected. In this way, a comprehensive detection of the dimming shed film can be achieved, and different states of detection can be performed on different areas on the same dimming shed film.

[0046] The working principle and use process of the present invention are as follows: first, the two ends of the dimming shed film are moved to between the two second buffer plates 414 inside the two convergence shells 401 through the two outlets 402 respectively, and then the second motor 411 is started to rotate the bidirectional screw rod 412. The rotation of the bidirectional screw rod 412 will drive the two clamping plates 413 to move towards each other through the bidirectional thread, and the dimming shed film is clamped by the two second buffer plates 414, and the spring 405 and air inside the cavity 404 on the clamping plate 413 are squeezed. When the light shed film is subjected to impact force, the clamped part of the dimming shed film is buffered. The staggered protrusions 415 are arranged on the second buffer plate 414 to increase the friction between the second buffer plate 414 and the dimming shed film, thereby improving the clamping strength and the clamping stability. Then, the first motor 408 is started to rotate the turntable 409, so that the excess part of the dimming shed film is wound on the surfaces of the two clamping plates 413, and the part of the dimming shed film above the outlet 402 is straightened, and the first buffer plate 407 is squeezed, so that the bent part of the dimming shed film is buffered by elastic force and air pressure.

[0047] At this time, the straightened part of the dimming shed film is located above the first support frame 206, and the second hydraulic cylinder 307 is used to move the second hydraulic rod 306 downward, driving the pressing plate 305 downward to squeeze the straightened dimming shed film. The strength of the dimming shed film in the straightened state can be tested by the pressure sensor arranged in the pressing plate 305. When it is necessary to test the strength of the dimming shed film in the roof state, it is only necessary to move the first hydraulic rod 201 upward through the first hydraulic cylinder 202, and drive the first support frame 206 upward through the lifting plate 210, so that the semicircular frame formed by the first support frame 206 and the second support frame 207 can support the dimming shed film into a semicircle from the bottom of the dimming shed film. In this process, the turntable 409 needs to rotate to release a part of the wound dimming shed film so that it can be supported, and then the pressing plate 305 is moved downward to detect the strength of the dimming shed film in the semicircular state of the roof.

[0048] At the same time, the cylinder 102 can be used to move the telescopic rod 103 in the direction away from the cylinder 102, driving the first slide 104 to move in the direction away from the second slide 109, so that the first rack 105 drives the gear 110 to rotate. The rotation of the gear 110 will drive the second slide 109 and the first slide 104 to move synchronously in the directions away from each other through the second rack 108, and apply stress to the two slide bars 208 through the two inclined grooves 107, so that the slide bars 208 drive the second support frame 207 upward, and drive the second support frame 207 and the rack inside the first support frame 206 to rotate through the hinge, and adjust the arc formed at the top of the first support frame 206 and the second support frame 207, so that the device can simulate roofs of different shapes and specifications, and detect the strength of the dimming film on different roofs.
