[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the specification drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present utility model: A geomembrane damage detection device includes a detection table 1. A first limit groove 2 is provided on the inner wall of the detection table 1. A lower brush 3 is fixedly connected to the inner wall of the detection table 1. A support column 4 is fixedly connected to the inner wall of the detection table 1. One end of the support column 4 is fixedly connected to a fixed block 5. A first motor 6 is provided on the upper surface of the fixed block 5. The output end of the first motor 6 is fixedly connected to a first rotating shaft 7. A limit wheel 8 is fixedly connected to the lower surface of the fixed block 5. The output end of the first rotating shaft 7 is fixedly connected to a crank 9. The lower surface of the crank 9 is fixedly connected to a rotating column 10. The outer wall of the rotating column 10 is slidably connected to a rectangular frame 11. The outer wall of the rectangular frame 11 is fixedly connected to an upper brush 12. The outer wall of the upper brush 12 is slidably connected to the outer wall of the limit wheel 8. The outer wall of the upper brush 12 is slidably connected to the inner wall of the first limit groove 2. A rotating component is provided on the inner wall of the detection table 1; The rotating component includes a first electric roller 13. The outer wall of the first electric roller 13 is rotatably connected to the inner wall of the detection table 1. A second electric roller 14 is rotatably connected to the inner wall of the detection table 1. A detection component is provided on the inner wall of the detection table 1;

[0026] Specifically, in addition to driving the upper brush 12 to reciprocate through the rectangular frame 11 to clean the dust on the upper surface of the geomembrane to be detected, when the lower surface of the geomembrane to be detected passes over the upper surface of the lower brush 3, it will clean the dust on the lower surface of the geomembrane. The detection table 1 can fix the support column 4, and the support column 4 can fix the fixed block 5 and thus support the first motor 6, ensuring that the first motor 6 maintains stable output during operation. The upper surface of the lower brush 3 and the lower surface of the upper brush 12 can jointly clean the dust on the surface of the geomembrane to be detected. The limiting wheel 8 is fixedly connected to the lower surface of the fixed block 5, enabling the rectangular frame 11 to cause the upper brush 12 to always move along a straight line when driving the upper brush 12, thereby improving the quality of dust cleaning. When the first electric roller shaft 13 and the second electric roller shaft 14 are started simultaneously, the geomembrane after the detection can be continuously conveyed.

[0027] Refer to Figure 1 , the detection assembly includes a light source induction receiver 15, the outer wall of the light source induction receiver 15 is fixedly connected to the inner wall of the detection table 1, and a light source emitter 16 is fixedly connected to the upper surface of the detection table 1;

[0028] Specifically, the light source emitter 16 generates a light source signal. If the geomembrane light source induction receiver 15 receives the light source signal emitted by the light source emitter 16, it means that this section of the geomembrane is damaged.

[0029] Refer to Figure 1 and Figure 4 , a second motor 17 is arranged inside the detection table 1, and the output end of the second motor 17 is fixedly connected to a second rotating shaft 18; the outer wall of the second rotating shaft 18 is rotatably connected inside the detection table 1, and a gear 19 is fixedly connected to the outer wall of the second rotating shaft 18; the outer wall of the gear 19 is meshed with a rack 20, and a moving column 21 is fixedly connected to the upper surface of the rack 20; the outer wall of the moving column 21 is slidably connected inside the detection table 1, a limiting cap 22 is fixedly connected to the outer wall of the moving column 21, and one end of the moving column 21 is fixedly connected to a fixing plate 23; a light transmission groove 24 is formed in the outer wall of the fixing plate 23, and a second limiting groove 25 is formed in the outer wall of the fixing plate 23;

[0030] Specifically, a light-transmitting groove 24 is provided on the outer wall of the fixing plate 23, which can prevent the fixing plate 23 from blocking the detection part of the geomembrane during the fixation of the conveying geomembrane, thereby further improving the detection effect. The geomembrane to be detected can be fixed and conveyed along the inner wall of the second limiting groove 25 through the second limiting groove 25 provided on the outer wall of the fixing plate 23, so that the geomembrane can always pass through the detection area formed by the light source emitter 16 and the light source induction receiver 15 smoothly during the detection process, improving the detection accuracy and detection efficiency. The limiting cap 22 is fixedly connected to the outer wall of the moving column 21, which can play a role in limiting the fixing plate 23, and thus can ensure that the fixing plate 23 does not drive the moving column 21 to slide out of the inside of the detection table 1 during the process of driving the fixing plate 23 to move. The second rotating shaft 18 can play a role in rotating the gear 19 and thus play a role in moving the rack 20.

[0031] Working principle: When the device needs to be used, first send the geomembrane into the gap formed by the lower brush 3 and the upper brush 12. Then, pass one end of the geomembrane to be detected through the gap between the first electric roller 13 and the second electric roller 14 to make it in a fitting state. Then start the first electric roller 13 and the second electric roller 14. The start of the second electric roller 14 and the second electric roller 14 can convey the geomembrane above the detection table 1. During the conveyance of the geomembrane, start the first motor 6 to make the first rotating shaft 7 rotate inside the fixed block 5 and drive the crank 9 to rotate. The rotation of the crank 9 causes the rotating column 10 to rotate accordingly, and makes the rotating column 10 slide on the inner wall of the rectangular frame 11 and drive the rectangular frame 11 to rotate. However, since the outer wall of the rectangular frame 11 is fixedly connected with the upper brush 12, and in addition, the upper brush 12 slides on the outer wall of the limiting wheel 8 to form a limit for the upper brush 12, the rectangular frame 11 drives the upper brush 12 to reciprocate to clean the dust on the upper surface of the geomembrane to be detected, so as to achieve the effect of cleaning the dust on the surface of the geomembrane before detecting the geomembrane, and then the damaged area can be made more clearly visible, improving the accuracy of detection. When the geomembrane to be detected passes under the light source emitter 16, the light source emitter 16 will generate a light source signal. If the geomembrane light sensor receiver 15 receives the light source signal emitted by the light source emitter 16, it means that this section of the geomembrane is damaged. Start the second motor 17 arranged inside the detection table 1. The start of the second motor 17 makes the second rotating shaft 18 rotate inside the detection table 1 and also drives the gear 19 to rotate, thereby making the rack 20 move, prompting the rack 20 to drive the moving column 21 to slide inside the detection table 1 and also drive the limiting cap 22 to move. When the moving column 21 slides inside the detection table 1, it can drive the fixing plate 23 to move, so as to achieve the effect of fixing the geomembrane during the conveying and detecting process, and then maintain its stability, ensuring that the detection device can accurately detect it, improving the accuracy and reliability of detection. This device can not only achieve the effect of cleaning the dust on the surface of the geomembrane before detecting the geomembrane, and then make the damaged area more clearly visible, improving the accuracy of detection. In addition, it can also achieve the effect of fixing the geomembrane during the conveying and detecting process, and then maintain its stability, ensuring that the detection device can accurately detect it, improving the accuracy and reliability of detection.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
