Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-6 The present invention provides the following technical solution: A sampling device for the bonding strength of waterproof membrane in water conservancy projects includes a base 1, a sampling frame 2 on the top of the base 1, a sampling component 4 inside the sampling frame 2, a dust collection component 5 on the inner side of the sampling component 4, the sampling component 4 including an annular toothed ring 401 rotatably connected inside the sampling frame 2, a sampling cutter 402 fixedly connected to the inner side of the annular toothed ring 401, a drive gear 403 meshing with the top of the annular toothed ring 401, a synchronous pulley 404 fixedly connected to the inner side of the drive gear 403, a transmission belt 405 drivingly connected to the outer side of the synchronous pulley 404, a drive motor 406 on the top of the sampling frame 2, and the output end of the drive motor 406 fixedly connected to the right synchronous pulley 404.

[0021] In this embodiment: By activating the drive motor 406 located behind the protective shell 3 at the top of the sampling frame 2, the output of the drive motor 406 drives the synchronous pulley 404 fixed thereto to rotate. The synchronous pulley 404 transmits power to another set of synchronous pulleys 404 through the transmission belt 405 meshing on its outer side, causing the drive gear 403 fixedly connected to the synchronous pulley 404 to rotate accordingly. Since the drive gear 403 is rotatably connected to the protective shell 3 on both sides through the rotating shaft 12, the drive gear 403 remains stable during rotation and always precisely meshes with the annular gear ring 401, thereby driving the annular gear ring. The sampling cutter 402, fixed inside the sampling frame 2, rotates at a constant speed. The sampling cutter 402, fixed inside the annular toothed ring 401, rotates synchronously with the annular toothed ring 401, making annular cuts on the waterproof membrane fixed by the limiting clamp 11. Throughout the process, the drive motor 406 provides stable power. Through the coordinated transmission of the synchronous wheel 404, the transmission belt 405, and the drive gear 403, the sampling cutter 402 rotates at a uniform speed and the cutting trajectory is regular. This avoids damage to the original bonding interface between the membrane and the substrate due to uneven cutting force or speed, and finally cuts out a sampling specimen with neat edges and an intact bonding interface.

[0022] Specifically, such as Figure 5 As shown, the dust collection assembly 5 includes a filter frame 501 fixedly connected to the outside of the sampling frame 2. An annular dust collection pipe 502 is connected to the left side of the filter frame 501. The annular dust collection pipe 502 is located inside the annular toothed ring 401. A double-ended dust collection head 503 is connected to the inside of the annular dust collection pipe 502.

[0023] Specifically, such as Figure 5 As shown, a filter plate 504 is slidably connected to the top of the filter frame 501, and a handle rod 505 is fixedly connected to the top of the filter plate 504.

[0024] Specifically, such as Figure 5 As shown, a control fan 506 is connected to the right side of the filter frame 501, and the control fan 506 is located on the right side of the filter plate 504.

[0025] In this embodiment: When the sampling component 4 starts cutting, the control fan 506 on the right side of the filter frame 501 is started. The control fan 506 generates negative pressure suction, creating a low-pressure environment inside the filter frame 501. This negative pressure suction is transmitted through the annular suction pipe 502 connected to the left side of the filter frame 501 to the double-ended suction head 503 located inside the annular toothed ring 401. The double-ended suction head 503 is directly aimed at the cutting area, sucking in the roll material debris generated during the cutting process in real time. The debris enters the filter frame 501 with the airflow through the annular suction pipe 502. When the airflow passes through the filter plate 504 inside the filter frame 501, the filter plate 504 intercepts and filters the debris, preventing the debris from entering the control fan 506 and causing equipment damage. After the sampling operation is completed, the control fan 506 is turned off, and the filter plate 504 is pulled out from the top of the filter frame 501 by pulling the lever 505 on the top of the filter plate 504, and the debris intercepted on the filter plate 504 is cleaned up.

[0026] Specifically, such as Figure 6 As shown, a placement frame 6 is fixedly connected to both sides of the top of the base 1, a rigid spring 7 is fixedly connected inside the placement frame 6, and a placement seat 8 is fixedly connected to the top of the rigid spring 7.

[0027] Specifically, such as Figure 6 As shown, horizontal plates 9 are fixedly connected to both sides of the top of the base 1, and a drive cylinder 10 is fixedly connected to the outer side of the horizontal plate 9. A limit clamp 11 is fixedly connected to the telescopic end of the drive cylinder 10.

[0028] In this embodiment: by setting up a placement frame 6, a rigid spring 7, and a placement seat 8, before the sampling operation begins, the waterproof membrane to be tested and its adhered base layer are placed together on the placement seat 8. The placement frame 6 provides rigid support to the placement seat 8, preventing lateral displacement of the placement seat 8 when bearing the material, thus providing a stable bearing foundation for subsequent sampling. When the material is placed on the placement seat 8, the rigid spring 7 at the bottom of the placement seat 8 will adapt to the weight of the material, playing a buffering role and preventing damage to the material due to the impact force during placement. At the same time, it allows the placement seat 8 to better fit the bottom of the material, ensuring that the material remains stable during subsequent cutting. After the material is placed on the placement seat 8, the drive cylinder 10 and the limiting clamp 11 are set up. Then, the drive cylinder 10 on the outside of the drive cylinder 9 is started. The telescopic end of the drive cylinder 10 slowly extends inward, driving the limiting clamp 11 to gradually approach the two sides of the material. When the limiting clamp 11 is in close contact with the surface of the material and reaches the preset clamping force, the drive cylinder 10 stops running. At this time, the limiting clamp 11 firmly fixes the material on the placement seat 8, preventing the material from shifting or shaking during the subsequent cutting process. This ensures the accuracy of the cutting trajectory of the sampling cutter 402, guarantees the edge integrity of the sampling specimen, and prevents the cutting deviation caused by material displacement from damaging the bonding interface between the roll material and the base layer.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, a protective shell 3 is fixedly connected to the top of the sampling frame 2, and the rear side of the protective shell 3 is fixedly connected to the drive motor 406.

[0030] Specifically, such as Figure 1 , Figure 2 As shown, rotating shafts 12 are fixedly connected to both sides of the drive gear 403, and the rotating shafts 12 are rotatably connected to the protective shell 3.

[0031] In this embodiment: By setting a protective shell 3, during the operation of the sampling component 4, the protective shell 3 completely encloses the drive motor 406, synchronous pulley 404, transmission belt 405 and other transmission components, isolating external dust, sand and other impurities from entering the transmission structure, preventing impurities from affecting the meshing accuracy of synchronous pulley 404 and transmission belt 405, and ensuring transmission stability. By setting a rotating shaft 12, when the drive motor 406 drives synchronous pulley 404 to rotate, and then drives drive gear 403 to rotate, the rotating shaft 12 rotates smoothly around the connection point of the protective shell 3, providing guidance and support for drive gear 403, ensuring that drive gear 403 always maintains precise meshing with ring gear 401 during rotation, avoiding disengagement or transmission jamming due to lack of support, ensuring uniform rotation of ring gear 401 and sampling cutter 402, and improving cutting accuracy.

[0032] Specifically, such as Figure 2 As shown, a sealing sleeve 13 is fixedly connected to the inner wall of the sampling frame 2. The sealing sleeve 13 is made of rubber.

[0033] Specifically, such as Figure 6 As shown, an elastic protective pad 14 is fixedly connected to the top of the placement seat 8.

[0034] In this embodiment: By setting a sealing sleeve 13, the rubber sealing sleeve 13 is tightly fitted to the inner wall of the sampling frame 2, forming a closed sealed space around the cutting area. When the sampling cutting blade 402 cuts the material, the sealing sleeve 13 is in close contact with the material surface, isolating the cutting area from the external environment, preventing external dust and impurities from entering the cutting area, and avoiding impurities adhering to the cutting blade or material surface and affecting the cutting effect. By setting an elastic protective pad 14, when the material to be sampled is placed on the placement seat 8, the elastic protective pad 14 is in direct contact with the material surface. Its softness can prevent the material surface from hard contacting the placement seat 8, causing scratches, indentations and other damage, protecting the original state of the material. At the same time, the elastic protective pad 14 can increase the friction between the material and the material, assisting the limiting clamp 11 to further fix the material, preventing the material from slightly sliding during placement or cutting, and improving the stability of the material fixation.

[0035] Working principle: When using this water conservancy project waterproof membrane bonding strength sampling device, the waterproof membrane to be tested and the base layer are first placed on the placement seat 8 on the top of the base 1. The rigid spring 7 at the bottom of the placement seat 8 provides a buffering effect, and the elastic protective pad 14 at the top of the placement seat 8 can prevent the surface of the material to be sampled from being damaged due to contact force. Then, the drive cylinders 10 on the horizontal plates 9 on both sides of the base 1 are activated, driving the limiting clamp 11 to move inward, firmly clamping the material to be sampled, preventing the material from shifting during the sampling process and affecting the cutting accuracy. The sampling frame 2 is the core. The sampling operation is supported by a protective shell 3 on top, which protects the internal transmission components. When the drive motor 406 behind the protective shell 3 is activated, its output drives a connected synchronous pulley 404 to rotate. This synchronous pulley 404, via a transmission belt 405, drives another synchronous pulley 404 to rotate synchronously. This, in turn, causes the drive gear 403, fixedly connected to the synchronous pulley 404, to rotate stably around the shaft 12. Since the drive gear 403 meshes with the ring gear 401, the ring gear 401 rotates within the sampling frame 2. The inner side of the ring gear 401... The sampling cutter 402 rotates synchronously to make a circular cut on the firmly clamped waterproof membrane. The rubber sealing sleeve 13 on the inner wall of the sampling frame 2 ensures the sealing of the cutting area, preventing external impurities from interfering with the cutting process and preventing the spillage of cutting debris. Simultaneously with the cutting operation, the dust collection component 5 starts working. The control fan 506 on the right side of the filter frame 501 generates negative pressure suction, which is applied through the annular suction pipe 502 connected to the left side of the filter frame 501, and then through the double-ended suction head 503 inside the annular suction pipe 502 to remove the cut material. During the process, the roll material debris generated is sucked into the annular suction pipe 502, and then sucked into the filter frame 501. The debris is filtered and trapped by the filter plate 504 that slides inside the filter frame 501. The pull rod 505 on the top of the filter plate 504 makes it easy to pull out the filter plate 504 and clean up the trapped debris. Throughout the process, all components work together to ensure that the cutting process is stable and controllable, effectively avoiding damage to the original bonding interface between the waterproof roll material and the substrate. Finally, a structurally intact sampling specimen is obtained to meet the requirements of subsequent waterproof roll material bonding strength testing.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
