[0017] (2) The present invention provides a long-distance pultruded carbon fiber composite material detection system. When the clamping block 1 generates a force moving away from each other, the carbon fiber composite plate will be deformed under the action of the clamping block 1 and the clamping block 2 clamping the carbon fiber composite plate. The clamping block 2 will also move in the process of the carbon fiber composite plate being generated. At this time, the clamping block 2 will drive the two L-shaped slide bars to move away from each other, and the L-shaped slide bar will drive the support spring to compress and deform.

[0035] As Figure 2 shown, two closing mechanisms 6 are arranged on the detection frame 1. The closing mechanism 6 includes a strip-shaped groove 601 opened on the left side of the detection frame 1. A clamping box two 602 is fixedly installed on the top inner wall of the strip-shaped groove 601. A limiting round rod 603 is fixedly installed in the strip-shaped groove 601. The limiting round rod 603 penetrates through the clamping box one 506 and is slidably connected to the clamping box one 506. A limiting spring 604 is sleeved on the limiting round rod 603. The bottom end of the limiting spring 604 is fixedly connected to the clamping box one 506, and the top end of the limiting spring 604 is fixedly connected to the clamping box two 602.

[0036] After pulling out the round plate 805, the clamping box one 506 will drive the carbon fiber composite board 608 to leave the clamping box two 602 under the elastic force of the limiting spring 604, and at this time, the carbon fiber composite board 608 can be taken out.

[0037] As Figure 5 shown, two movable springs 605 are respectively fixedly installed on the right inner walls of the clamping box two 602 and the clamping box one 506. A clamping block two 606 is slidably installed in the clamping box two 602. The left ends of several movable springs 605 are respectively fixedly connected to the clamping block two 606 and the clamping block one 507. A plurality of rubber strips 607 are respectively fixedly installed on the sides of the clamping block two 606 and the clamping block one 507 that are close to each other.

[0038] After the clamping block two 606 and the clamping block one 507 clamp the carbon fiber composite board 608, the clamping plates 504 will also generate a force to move away from each other. At this time, the clamping plates 504 will push the two clamping blocks one 507 to move away from each other, which is convenient for detecting the tensile strength.

[0039] As Figure 5As shown, a carbon fiber composite board 608 is provided on the top of the first clamping block 507, and two trapezoidal limit plates 609 are fixedly installed on the right side of the second clamping block 606. The bottoms of the two trapezoidal limit plates 609 are both in contact with the carbon fiber composite board 608.

[0040] Under the action of the first clamping block 507 and the second clamping block 606 clamping the carbon fiber composite board 608, the carbon fiber composite board 608 will deform, and the second clamping block 606 will also move in position during the process of the carbon fiber composite board 608 deforming.

[0041] As Figure 6 shown, a detection mechanism 7 is provided in the detection frame 1. The detection mechanism 7 includes a strip-shaped mounting plate 701 fixedly installed in the detection frame 1. A tensile pressure sensor 702 is fixedly installed on the top of the strip-shaped mounting plate 701. An L-shaped sliding rod 703 is slidably installed in the tensile pressure sensor 702. One end of each of the two L-shaped sliding rods 703 away from each other extends outside the tensile pressure sensor 702, and one end of each of the two L-shaped sliding rods 703 away from each other is fixedly connected to the two second clamping blocks 606 respectively. Circular plates 704 are fixedly installed at one end of each of the two L-shaped sliding rods 703 close to each other. Support springs 705 are respectively sleeved on the two L-shaped sliding rods 703. One end of each of the two support springs 705 close to each other is fixedly connected to the two circular plates 704 respectively. One end of each of the two support springs 705 away from each other is fixedly connected to the tensile pressure sensor 702.

[0042] The second clamping block 606 will drive the two L-shaped sliding rods 703 away from each other. The L-shaped sliding rods 703 will drive the support springs 705 to undergo compressive deformation. The force generated during this process will be transmitted to the tensile pressure sensor 702. When the carbon fiber composite board 608 can withstand a predetermined tensile force, it can stop, and the tensile test of this carbon fiber composite board 608 is qualified.

[0043] As Figure 7 shown, fixing mechanisms 8 are respectively provided on the two first clamping boxes 506. The fixing mechanism 8 includes an L-shaped fixing plate 801 fixedly installed on the front of the first clamping box 506. A rectangular fixing groove 802 is formed in the L-shaped fixing plate 801. A trapezoidal fixing block 803 is slidably installed in the rectangular fixing groove 802. A rectangular limiting rod 804 is fixedly installed on the front of the trapezoidal fixing block 803. The front end of the rectangular limiting rod 804 extends outside the rectangular fixing groove 802 and is slidably connected to the rectangular fixing groove 802.

[0044] During the process of the first clamping box 506 driving the carbon fiber composite board 608 to rise, it will drive the L-shaped fixing plate 801 to rise. The L-shaped fixing plate 801 will drive the trapezoidal fixing block 803 to rise. When the trapezoidal fixing block 803 touches the strip-shaped mounting plate 701, it will slide into the rectangular fixing groove 802.

[0045] AsFigure 7 As shown, a circular plate 805 is fixedly installed at the front end of the rectangular limiting rod 804. A fixing spring 806 is sleeved on the rectangular limiting rod 804. The front end of the fixing spring 806 is fixedly connected to the rectangular fixing groove 802, and the end of the fixing spring 806 is fixedly connected to the trapezoidal fixing block 803.

[0046] When the trapezoidal fixing block 803 leaves the strip-shaped mounting plate 701, the carbon fiber composite plate 608 at this time will also be clamped by the second clamping block 606 and the first clamping block 507. Under the elastic force of the fixing spring 806, the trapezoidal fixing block 803 will pop out again. At this time, the second clamping block 606 and the first clamping block 507 complete the self-locking fixation of the carbon fiber composite plate 608, preparing for the bending test.

[0047] As Figure 8 shown, a bending detection mechanism 9 is provided on the threaded rod 3. The bending detection mechanism 9 includes an inner threaded plate two 901 threadedly sleeved on the threaded rod 3. The limiting slide rod 4 penetrates through the inner threaded plate two 901 and is slidably connected to the inner threaded plate two 901. Two T-shaped round rods 902 are fixedly installed at the bottom of the inner threaded plate two 901. Cylindrical pressure sensors 903 are slidably sleeved on the two T-shaped round rods 902 respectively.

[0048] The inner threaded plate two 901 drives the T-shaped round rod 902 to descend. The T-shaped round rod 902 will drive the cylindrical pressure sensor 903 to contact the surface of the carbon fiber composite plate 608. When the inner threaded plate two 901 continues to descend, it will drive the T-shaped round rod 902 to press against the cylindrical pressure sensor 903. The cylindrical pressure sensor 903 will apply force to the carbon fiber composite plate 608. At this time, it is a four-point bending test, improving the convenience of the device.

[0049] During use, place the produced carbon fiber composite plate 608 on the two clamping blocks 507. Then start the drive motor 2. The drive motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 drives the first internally threaded plate 501 to rise. The first internally threaded plate 501 drives the special-shaped plate 502 to move. The special-shaped plate 502 drives the clamping plate 504 and the arc-shaped rod 503 to rise simultaneously. The clamping plate 504 maintains its angular state under the elastic force of the arc-shaped spring 505. During the rising process of the clamping plate 504, it will enter the limiting groove 508 and press against the limiting groove 508. At this time, the limiting groove 508 will drive the first clamping box 506 to rise. The first clamping box 506 will drive the carbon fiber composite plate 608 to rise. The carbon fiber composite plate 608 will come into contact with the second clamping block 606. At this time, when the second clamping block 606 and the first clamping block 507 clamp the carbon fiber composite plate 608, the clamping plates 504 will still generate a force to move away from each other. At this time, the clamping plates 504 will push the two first clamping blocks 507 to move away from each other, which is convenient for detecting the tensile strength. When the first clamping blocks 507 generate a force to move away from each other, under the action of the first clamping blocks 507 and the second clamping blocks 606 clamping the carbon fiber composite plate 608, the carbon fiber composite plate 608 will deform, and the second clamping blocks 606 will also move in position during the generation of the carbon fiber composite plate 608. At this time, the second clamping blocks 606 will drive the two L-shaped sliding rods 703 to move away from each other. The L-shaped sliding rods 703 will drive the support spring 705 to undergo a compressive deformation. The force generated during this process will be transmitted to the tensile pressure sensor 702. When the carbon fiber composite plate 608 can withstand the predetermined tensile force, it can be stopped, and the tensile test of this carbon fiber composite plate 608 is qualified.

[0050] During the process of the clamping box 506 driving the carbon fiber composite board 608 to rise, the L-shaped fixing plate 801 will be driven to rise. The L-shaped fixing plate 801 will drive the trapezoidal fixing block 803 to rise. When the trapezoidal fixing block 803 touches the strip-shaped mounting plate 701, it will slide into the rectangular fixing groove 802. At this time, the fixing spring 806 undergoes a compressive deformation. When the trapezoidal fixing block 803 leaves the strip-shaped mounting plate 701, the carbon fiber composite board 608 will also be clamped by the second clamping block 606 and the first clamping block 507. Under the elastic force of the fixing spring 806, the trapezoidal fixing block 803 will pop out again. At this time, the second clamping block 606 and the first clamping block 507 complete the self-locking fixation of the carbon fiber composite board 608, preparing for the bending test. Then, reverse the drive motor 2. The drive motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 drives the first internal threaded plate 501 and the special-shaped plate 502 to descend. The clamping plate 504 will also leave the limit groove 508. At this time, the second clamping block 606 and the first clamping block 507 still fix the carbon fiber composite board 608. At the same time, the second internal threaded plate 901 descends together. The second internal threaded plate 901 drives the T-shaped round rod 902 to descend. The T-shaped round rod 902 will drive the cylindrical pressure sensor 903 to contact the surface of the carbon fiber composite board 608. When the second internal threaded plate 901 continues to descend, it will drive the T-shaped round rod 902 to press against the cylindrical pressure sensor 903. The cylindrical pressure sensor 903 will apply a force to the carbon fiber composite board 608. At this time, it is a four-point bending test, improving the convenience of the device.
