Description

Technical Field

[0001] This invention relates to the field of fishing net line technology, and more specifically, to a fishing net line tensile strength testing device. Background Technology

[0002] Fishing net line is a specialized linear material used in fishing, aquaculture, and other related operations. Its main functions include connecting the various components of fishing gear and fixing the gear in place in the aquatic environment, ensuring the stable operation of the entire system. This type of line is usually made of high-strength synthetic fibers or natural materials, possessing excellent durability and environmental adaptability. In fisheries production, the tensile strength of the fishing net line is particularly critical, as it directly relates to the safety of fishing operations, preventing gear failure or accidents due to line breakage. At the same time, high tensile strength also helps improve operational efficiency, reducing time and cost losses due to repairs and replacements, and has a significant impact on the overall economic benefits of the fisheries industry.

[0003] According to patent document CN119688468A, a device and method for testing the tensile strength of fishing net lines are disclosed, relating to the field of fishing net line tensile strength testing technology. The device includes a loading frame, on which a drive motor is fixedly mounted. A winding roller rotates through the inner and outer walls of the loading frame and is fixedly connected to the output end of the drive motor. A tensile testing mechanism is provided on the side of the loading frame away from the drive motor. The device also includes a fixing device, auxiliary devices, and protective devices. The fixing device includes a mounting plate, a fixing rod, a protective plate, a lifting rod, a first spring, a connecting rod, a rubber block, a pull rod, and an L-shaped plate. When the protective plate is closed, the fishing net fitted onto the fixing rod is automatically and effectively fixed, preventing sudden slippage. Simultaneously, the three fixing points ensure more even force distribution on the fishing net during testing, contributing to improved testing effectiveness.

[0004] In the tensile strength testing of fishing net lines, two clamps are typically used to hold both ends of a section of the line. A tensioning device is then used to apply gradually increasing tension to test its maximum withstand capacity. However, before the actual tensile test, each section of fishing net line requires a series of complex and time-consuming fixing operations. These operations include adjusting the position of the clamps, ensuring the line is evenly clamped, and preventing slippage or tilting during stress. This process not only consumes a significant amount of manual time and effort but also makes it difficult to guarantee the stability and consistency of the clamping due to differences in the skill level, experience, or operating habits of different operators. Instability in the fixing effect directly affects the uniformity of the applied tension, thus adversely affecting the accuracy of the final test data. This is especially true when conducting continuous multi-point or segment-by-segment testing on long sections of fishing net line, where operators must repeatedly perform these tedious fixing steps. This significantly increases workload, severely slows down the overall testing progress, and drastically reduces efficiency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a tensile strength testing device for fishing net lines. The technical problem this invention aims to solve is that, in the testing process, each segment of fishing net line to be tested typically requires a series of complex and time-consuming fixing operations before formal tensile testing. These operations include adjusting the position of the clamping components, ensuring the fishing net line is evenly clamped, and preventing slippage or skewing during the stress process. This process can not only consume a lot of manual time and effort, but also easily lead to difficulties in ensuring the stability and consistency of the clamping due to differences in the technical level, experience, or operating habits of different operators. The instability of the fixing effect will directly affect the uniformity of the applied tensile force, thus adversely affecting the accuracy of the final test data. Especially when conducting continuous multi-point or segment-by-segment testing on a long section of fishing net line, the operator must repeatedly perform the above tedious fixing steps, which not only significantly increases the workload but also seriously slows down the overall testing progress, resulting in a significant reduction in efficiency.

L-shaped side plates 12112 are fixedly connected to the left and right sides of the inner side of the two sets of concave side plates 121. The front and rear sides of the inner wall of the multiple sets of L-shaped side plates 12112 are fitted onto the outer wall of the multiple sets of columnar horizontal push rods 12111.The inner ends of multiple sets of columnar push rods 12111 extend to the inner sides of multiple sets of L-shaped side plates 12112 and are all fixedly connected to clamping plates 12113; When it is necessary to perform tensile testing on the fishing net line, the fishing net line is first pulled and wound around the two ends of the guide mechanism 2 to the winding point at the front of the guide mechanism 2. At this time, the outer wall of the fishing net line is on the inner side of the two sets of clamping plates 12113 on the left and the two sets of clamping plates 12113 on the right. When testing is required, the motor 1114 is started. After the motor 1114 is started, its output end drives the turntable 1115 to start rotating. The columnar abutment block 1116 then makes a circular motion. Since the outer wall of the columnar abutment block 1116 is fitted with an elliptical sliding block 1117, the elliptical sliding block 1117 makes a reciprocating linear motion under the drive of the columnar abutment block 1116, which in turn drives the L-shaped push-pull rod 1118 to move back and forth. The front side of the L-shaped push-pull rod 1118 is fixedly connected to the bottom middle of the front concave sliding plate 11111, so it will push the front concave sliding plate 11111 to slide back and forth along the guide side rod 1112. At the same time, the diamond-shaped rotating block 1119 at the bottom of the control board 1111 rotates under the action of the rotating rod 11110, causing the two rotating rods 11110 to swing accordingly, thereby causing the two concave sliding plates 11111 to move synchronously. The columnar horizontal connecting rod 11112 at the middle of the outer side of the concave sliding plate 11111 will drive the inverted convex sliding plate 11113 to move, which in turn causes the elliptical abutment plate 11114 to push the swing rod abutment block 11117, and the swing rod push block 11116 also moves accordingly, ultimately causing the swing rod 11115 to swing around the rotating connection point at the bottom of the control board 1111. The transition block 11118 at the bottom of the swing rod 11115 and the second transition block 11120 at the bottom of the swing short rod 11119 will pull the concave side plate pull plate 123, causing the concave side plate 121 to move outward under the guidance of the side concave guide plate 113. The two sets of concave side plates 121 move to two points on a section of the fishing net line. At the same time, the movement of the concave side plate 121 drives the guide block 125 to move. Since the inner wall of the concave side plate 121 is slidably connected to the outer wall of the abutment plate 116, and the bottom of the pulley 1213 is in contact with the top of the abutment plate 116, during the movement of the concave side plate 121, the pulley 1213 rolls along the surface of the abutment plate 116 and is pushed by the abutment block 117, causing the second columnar upright rod 128 to move upward while the spring 1211 is compressed. This causes the cross slider 129 to slide on the columnar guide rod 127. The movement of the cross slider 129 is transmitted through components such as the arc-shaped push-pull rotating plate 1216, the concave hinge block 1217, and the rotating short plate 1218, ultimately driving the vertical Z-shaped push-pull plate 1219 to move. The vertical Z-shaped push-pull plate 1219 pushes the clamping plate 12113 to move inward through the columnar horizontal push rod hinge block 12110 and the columnar horizontal push rod 12111, thereby tightly clamping the fishing net line located between the left and right clamping plates 12113. As the motor 1114 continues to run, the above-mentioned motion process continues, the clamping force of the clamping plate 12113 on the fishing net line gradually increases, and the tension on the fishing net line also increases until it reaches the tension value required for testing, thereby completing the tensile test of the fishing net line. When inspecting a long section of fishing net line, it is only necessary to control the winding speed of the front winding part of the guide mechanism 2 to ensure that the fishing net line is taut during the inspection process. At the same time, the motor 1114 is started and runs continuously. According to the established transmission logic, all components work together continuously. Under reasonable control of the winding speed, the fishing net line always remains taut. If the fishing net line breaks during the inspection process, the device will immediately trigger the corresponding protection mechanism, such as the motor 1114 automatically stopping to avoid damage to components or other accidents caused by the breakage of the fishing net line. After completing one inspection, the control buttons on the control device can be used to reset all components. If it is necessary to inspect the next section of fishing net line or other parts of the same fishing net line, the device can be used for inspection.

[0022] like Figure 10As shown, the guide mechanism 2 includes a pallet 21. Second L-shaped support plates 22 are fixedly connected to both the left and right sides and the front and rear sides of the pallet 21. The bottom center of the pallet 21 is fixedly connected to the top center of the control assembly 111. A second motor connecting plate 23 is fixedly connected to the outer center of the second L-shaped support plate 22 on the front right side. A second motor 24 is fixedly connected to the top of the second motor connecting plate 23. A transmission disc 25 is fixedly connected to the output end of the second motor 24. A track 26 is fitted onto the outer wall of the transmission disc 25. A second transmission disc 211 is fitted onto the top of the inner wall of the track 26. A take-up plate 27 is fixedly connected to the front side of the top of the pallet 21. A take-up roller middle block 28 is fixedly connected to the center of the top of the take-up plate 27. Take-up roller side blocks 29 are fixedly connected to both the left and right sides of the top of the take-up plate 27. A take-up roller 210 is rotatably connected to the inner side of the two take-up roller side blocks 29. The right end of the take-up roller 210 extends to the right side of the take-up plate. The right end of the take-up roller 210 is fixedly connected to the left side of the second transmission disc 211 on the outer side of the side block 29 of the roller. A fishing net line sleeve roller 218 is fixedly connected to the rear side of the top of the support plate 21. T-shaped support plates 212 are fixedly connected to the front and rear sides of the top of the support plate 21. Concave guide blocks 213 are fixedly connected to the left and right sides of the top of the two T-shaped support plates 212. Second T-shaped upright plates 214 are fixedly connected to the middle of the top of the two T-shaped upright plates 212. Circuit control components 215 are fixedly connected to the middle of the inner side of the two second T-shaped upright plates 214. Monitoring plates 217 are fixedly connected to the left and right sides of the bottom of the two second T-shaped upright plates 214. Lines 216 are fixedly connected to the multiple sides of the top of the two monitoring plates 217. The inner ends of the two sets of lines 216 are fixedly connected to the multiple sides of the left and right sides of the circuit control components 215. The bottom of the two monitoring plates 217 is aligned with the top of the two sets of concave guide blocks 213. When testing the tensile strength of fishing net line, the two finished sections of fishing net line are first wound around both sides of the fishing net line sleeve roller 218, and one end is passed through both sides of the guide mechanism 2 and wound to both sides of the outer wall of the take-up roller 210 through two sets of concave guide blocks 213. During the test, the second motor 24 is started. After the second motor 24 is started, its output end drives the transmission disk 25 to start rotating. The transmission disk 25 drives the second transmission disk 211 to rotate synchronously through the track 26. Since the second transmission disk 211 is fixedly connected to the right end of the take-up roller 210, the take-up roller 210 starts to rotate under the drive of the second transmission disk 211, and takes up the fishing net line wound around both sides of its outer wall. During the take-up process, the fishing net line is guided by the two sets of concave guide blocks 213 to maintain a stable tension state and avoid slack or tangling. Meanwhile, the circuit control unit 215 is connected to the monitoring board 217 via line 216 to monitor the tension changes of the fishing net line in real time during the winding process, and transmits the monitoring data to the circuit control unit 215 for analysis and processing. If abnormal fluctuations in the tension of the fishing net line are detected, such as excessive tension caused by the quality problem of the fishing net line itself or the winding speed being too fast, the circuit control unit 215 will immediately send a control signal to adjust the speed of the second motor 24 via line 216, so that the winding speed of the winding roller 210 is reduced accordingly, thereby ensuring that the fishing net line is always in a suitable tension state during the detection process. As the take-up roller 210 continues to rotate, the control component 111 starts to operate according to the transmission logic described above, driving the clamping plate 12113 to move inward, tightly clamping the fishing net line located between the left and right clamping plates 12113. Then, following the predetermined transmission process, the clamping force on the fishing net line and the tension on the fishing net line increase continuously as the left and right clamping members 12 move outward, until the tensile strength test of the fishing net line is completed. If the fishing net line breaks during the detection process, the monitoring board 217 will immediately detect the sudden change in tension and transmit this signal to the circuit control unit 215 through the line 216. The circuit control unit 215 will quickly issue a control command to make the second motor 24 stop running automatically. At the same time, the motor 1114 in the control component 111 will also stop working to avoid damage to components or other accidents caused by the breakage of the fishing net line. After completing one test, the winding roller 210 is stopped and all components are reset by using the control button on the control device. If it is necessary to test the next section of fishing net line or other parts of the same fishing net line, simply repeat the above operation, wrap the new fishing net line around the fishing net line sleeve roller 218, and pass it through the guide mechanism 2 for winding and testing in the same way. When testing a long section of fishing net line, simply keep starting the second motor 24 and motor 1114 for continuous testing. During this period, the monitoring board 217 and the circuit control component 215 maintain real-time data interaction, accurately recording the tension change curve of each section of fishing net line, providing detailed data support for subsequent analysis of the tensile performance of the fishing net line.

[0023] Working principle of this invention: When performing tensile testing on fishing net lines, the two processed sections of fishing net line are first wound around both sides of the fishing net line roller 218, and one end is passed through both sides of the guide mechanism 2 and wound around to both sides of the outer wall of the take-up roller 210 through two sets of concave guide blocks 213. During testing, the second motor 24 is started. After the second motor 24 starts, its output end drives the transmission disc 25 to start rotating. The transmission disc 25 drives the second transmission disc 211 to rotate synchronously through the track 26. Since the second transmission disc 211 is fixedly connected to the right end of the take-up roller 210, the take-up roller 210 starts to rotate under the drive of the second transmission disc 211, and takes up the fishing net line wound around both sides of its outer wall. During the taking-up process, the fishing net line passes through the two sets of concave guide blocks 213. To maintain a stable tension and prevent slack or tangling, the outer walls of the fishing net line are located inside the two sets of clamping plates 12113 on the left and right sides, respectively. When testing is required, the motor 1114 is started. After the motor 1114 starts, its output end drives the turntable 1115 to rotate, and the columnar abutment 1116 moves in a circular motion. Since the outer wall of the columnar abutment 1116 is fitted with an elliptical sliding block 1117, the elliptical sliding block 1117 moves back and forth under the drive of the columnar abutment 1116, thereby driving the L-shaped push-pull rod 1118 to move back and forth. The front side of the L-shaped push-pull rod 1118 is fixedly connected to the bottom center of the front concave sliding plate 11111, so it will push the front concave sliding plate 11111. The sliding plate 11111 slides back and forth along the guide side rod 1112. At the same time, the diamond-shaped rotating block 1119 at the bottom of the control plate 1111 rotates under the action of the rotating rod 11110, causing the two rotating rods 11110 to swing accordingly, thereby making the two concave sliding plates 11111 move synchronously. The columnar horizontal connecting rod 11112 at the middle of the outer side of the concave sliding plate 11111 drives the inverted convex sliding plate 11113 to move, which in turn causes the elliptical abutment plate 11114 to push the swing rod abutment block 11117. The swing rod push block 11116 also moves accordingly, finally causing the swing rod 11115 to swing around the rotating connection point with the bottom of the control plate 1111. The connecting block 11118 at the bottom of the swing rod 11115 and the swing short rod 11119 The second transition block 11120 at the bottom pulls the concave side plate pull plate 123, causing the concave side plate 121 to move outward under the guidance of the concave guide plate 113. The two sets of concave side plates 121 move to two points on a section of the fishing net line. At the same time, the movement of the concave side plate 121 drives the guide block 125 to move. Since the inner wall of the concave side plate 121 is slidably connected to the outer wall of the abutment plate 116, and the bottom of the pulley 1213 is in contact with the top of the abutment plate 116, during the movement of the concave side plate 121, the pulley 1213 rolls along the surface of the abutment plate 116 and is pushed by the abutment block 117, causing the second columnar upright 128 to move upward. At the same time, the spring 1211 is compressed, which in turn causes the cross slider 129 to slide on the columnar guide upright 127.The movement of the cross slider 129 is transmitted through components such as the arc-shaped push-pull rotating plate 1216, the concave hinge block 1217, and the rotating short plate 1218, ultimately driving the vertical Z-shaped push-pull plate 1219 to move. The vertical Z-shaped push-pull plate 1219 pushes the clamping plate 12113 inward through the columnar horizontal push rod hinge block 12110 and the columnar horizontal push rod 12111, thereby tightly clamping the fishing net line located between the left and right clamping plates 12113. As the motor 1114 continues to run, the above movement process continues, and the clamping force of the clamping plate 12113 on the fishing net line gradually increases, and the tension on the fishing net line also continuously increases until the tension value required for detection is reached, thus completing the process. The tensile strength of paired fishing net lines is tested. Simultaneously, the circuit control unit 215 is connected to the monitoring board 217 via line 216 to monitor the tension changes of the fishing net lines in real time during the winding process. The monitoring data is transmitted to the circuit control unit 215 for analysis and processing. If abnormal fluctuations in the tension of the fishing net lines are detected, such as excessive tension due to quality issues with the net lines themselves or excessive winding speed, the circuit control unit 215 will immediately send a control signal to adjust the speed of the second motor 24 via line 216, thereby reducing the winding speed of the winding roller 210. This ensures that the fishing net lines remain under appropriate tension throughout the testing process. As rotation continues, control component 111 begins to operate according to the transmission logic described above, driving clamping plate 12113 to move inward, tightly clamping the fishing net line located between the left and right clamping plates 12113. Then, following the predetermined transmission process, the clamping force on the fishing net line and the tension on the fishing net line continuously increase as the left and right clamping members 12 move outward, until the tensile strength test of the fishing net line is completed. During the test, if the fishing net line breaks, monitoring board 217 will immediately detect the rapid change in tension and transmit this signal to circuit control component 215 through line 216. Circuit control component 215 quickly issues a control command to activate the second motor. The system automatically stops operating at speed 24, and simultaneously, motor 1114 in control component 111 also stops working to prevent damage to components or other accidents caused by broken fishing net line. After completing one inspection, the winding roller 210 stops rotating via the control button on the operating device, and all components reset. If it is necessary to inspect the next section of fishing net line or other parts of the same fishing net line, simply repeat the above operation, winding the new fishing net line onto the fishing net line sleeve roller 218 and passing it through the guide mechanism 2 for winding and inspection in the same way. When inspecting a long section of fishing net line, simply keep the second motor 24 and motor 1114 running continuously for continuous inspection.
