Abstract
Description
Technical Field
[0001] The present invention relates to the field of fishing net detection, and in particular to a fishing net tensile strength detection device. Background Art
[0002] The tensile strength of fishing nets is one of the key indicators for measuring their quality. Fishing nets with insufficient tensile strength are prone to breakage during use, which not only affects fishing efficiency but also poses a threat to the safety of fishing equipment and personnel. By conducting tensile strength testing on fishing nets, the quality of the fishing nets can be accurately assessed and potential quality problems can be discovered in a timely manner, thereby ensuring the reliability and safety of the fishing nets in actual use. At the same time, tensile strength testing is also an important quality control link in the fishing net production process, helping manufacturers optimize production processes, improve product quality, and enhance market competitiveness.
[0003] Most of the fishing net tensile strength testing devices currently available on the market can only perform testing in a room temperature air environment. However, fishing nets are exposed to a variety of different environmental conditions during actual use. For example, in deep-sea fishing, fishing nets are exposed to a low-temperature water environment. The low temperature may cause the performance of the fishing net material to change, thereby affecting its tensile strength. In some special fishing operation areas, such as waters near hot springs, fishing nets may be affected by high-temperature water. Existing testing devices are unable to simulate these complex environmental conditions, resulting in test results that cannot truly reflect the tensile strength performance of fishing nets in actual use and cannot meet the diverse needs of fishery production for fishing net quality testing.

The lower end output shaft of the dual-axis motor 4 extends into the slide 13 and is fixedly connected to the upper end of the reciprocating screw rod 27;
[0028] As an embodiment of the present invention, it also includes a temperature regulating mechanism, which cooperates with the lifting mechanism to realize detection under different environments. The temperature regulating mechanism includes an L-shaped plate 3 fixedly connected to the upper end of the shell 1, and a transmission 5 is installed at the lower end of the horizontal part of the L-shaped plate 3. The transmission 5 here adopts an accelerator to ensure the rapidity of gas circulation. The input shaft of the transmission 5 is fixedly connected to the upper end output shaft of the dual-axis motor 4. The output shaft of the transmission 5 passes through the L-shaped plate 3 and is fixedly connected to a rotating disk 25. A piston cylinder 22 is installed at the upper end of the horizontal part of the L-shaped plate 3. A piston block 23 that can slide back and forth is provided in the piston cylinder 22. The upper end of the rotating disk 25 is rotatably connected to a drive rod 24 at the eccentric position. The other end of the drive rod 24 is rotatably connected to the rear side of the piston block 23. The upper end of the shell 1 is fixedly connected to a temperature conducting box 9. A heating wire 11 is fixedly connected between the inner walls of the left and right sides of the temperature conducting box 9. A semiconductor refrigeration component 10 is installed at the upper end of the temperature conducting box 9. The cooling end of the semiconductor refrigeration component 10 extends to the inside of the temperature conducting box 9.
[0029] As an embodiment of the present invention, the front space of the piston cylinder 22 is connected to the top space in the shell 1 through the first one-way tube 7, and the front space of the piston cylinder 22 is connected to the rear space of the thermal conductive box 9 through the second one-way tube 8. The front space of the thermal conductive box 9 is connected with a connecting pipe 17. The inner bottom of the shell 1 is rotatably connected to a rotating tube 21. The lower end of the rotating tube 21 extends to the outside and is connected to the connecting pipe 17 through a rotary joint 20. The upper end of the rotating tube 21 is fixedly connected to a hollow disk 15, and the hollow disk 15 is connected to the rotating tube 21. A plurality of elbows 16 are fixedly connected to the outside of the rotating tube 21 at equal intervals. The elbows 16 are as shown in FIG. Figure 2 As shown, when it ejects high-speed airflow, it is subjected to a reaction force, which can realize the rotation of the bent pipe 16. The shell 1 is filled with water, and the page height of the water is one-third of the shell 1. A first one-way valve 19 is installed inside the first one-way tube 7, and a second one-way valve 26 is installed inside the second one-way tube 8. The flow direction of the first one-way valve 19 is one-way from the inside of the shell 1 to the front space of the piston cylinder 22, and the flow direction of the second one-way valve 26 is one-way from the front space of the piston cylinder 22 to the rear space of the temperature conduction box 9. When the rotating disk 25 rotates, internal circulating air flow can be generated.
[0030] In the present invention, when the sealing door 12 is opened and the initial state, the support plate 28 is in the highest position, one end of the fishing net line to be tested is fixed on the fixed column 18, and the other end is fixed on the vertical part of the L-shaped movable column 35, and the sealing door 12 is closed to ensure that the interior of the shell 1 is in a relatively closed state. At this time, the shell 1 is in a normal temperature air environment, and the electric telescopic rod 31 is started. The telescopic end of the electric telescopic rod 31 pushes the rectangular box 32 to slide to the right on the support plate 28. The rectangular slide 33 in the rectangular box 32 is initially in the left position under the action of the spring 34. When the rectangular box 32 slides to the right, the L-shaped movable column 35 moves to the right with the rectangular slide 33, thereby stretching the fishing net line and completing the tensile strength test in normal temperature air. After the test is completed, the electric telescopic rod 31 is started to restore it to its original state.
[0031] Then, the dual-shaft motor 4 is started, and its upper output shaft drives the input shaft of the transmission 5. The transmission 5 uses an accelerator to increase the speed of the output shaft. The output shaft of the transmission 5 drives the rotating disk 25. The drive rod 24, which is rotatably connected to the rotating disk 25 at its eccentric point, rotates with the rotating disk 25, thereby pushing the piston block 23 in the piston cylinder 22 back and forth. When the piston block 23 slides backward, the air at the top of the shell 1 is sucked into the space in front of the piston cylinder 22 through the first one-way tube 7; when the piston block 23 slides forward, the air in the space in front of the piston cylinder 22 is pressed into the space behind the thermal conductive box 9 through the second one-way tube 8. After the air enters the thermal conductive box 9, the heating wire 11 is energized to generate heat, heating the air. The heated air enters the rotating tube 21 through the connecting pipe 17, and is then sprayed into the water body in the shell 1 through the hollow disk 15 and multiple bends 16. At the same time, part of the hot air will also fill the upper air space in the shell 1, thereby heating the water body and air in the shell 1. During this process, the dual-axis motor 4 will also drive the reciprocating screw 27 to rotate, realizing the downward movement of the slider 14, thereby allowing the detection mechanism to move down to the water surface. When the detection mechanism moves down to the lowest position, the detection mechanism is completely inside the water surface. At this time, the water body is at a high temperature. At this time, another test is performed, which is a high-temperature water body test. After the test is completed, the electric telescopic rod 31 is started to restore it to its original state.
[0032] Then the dual-axis motor 4 continues to start, allowing the detection mechanism to move upward. During the upward movement, the heating wire 11 and the semiconductor refrigeration element 10 are not powered. When the detection mechanism moves to the uppermost position, it is located in the high-temperature air. At this time, another test is performed, namely the high-temperature air test. After the test is completed, the electric telescopic rod 31 is started to restore the original state;
[0033] Then the dual-axis motor 4 continues to start, allowing the detection mechanism to move downward. During the downward movement, the semiconductor refrigeration element 10 is powered to generate circulating air flow to cool the water. When the detection mechanism moves to the lowest position, the detection mechanism is completely inside the water surface. At this time, the water body is at a low temperature. At this time, another test is performed, which is a low-temperature water test. After the test is completed, the electric telescopic rod 31 is started to restore the original state.
[0034] Then the dual-axis motor 4 continues to start, allowing the detection mechanism to move upward. During the upward movement, the heating wire 11 and the semiconductor refrigeration element 10 are not powered. When the detection mechanism moves to the uppermost position, it is located in the low-temperature air. At this time, another test is performed, which is the low-temperature air test. After the test is completed, the electric telescopic rod 31 is started to restore the original state, and then the sealing door 12 is opened;
[0035] Furthermore, due to the arrangement of the plurality of curved pipes 16, after ejecting high-speed airflow, the curved pipes 16 are subjected to a reaction force, which enables the curved pipes 16 to rotate. The rotation of the curved pipes 16 can stir the water body and promote the uniformity of temperature regulation.
