in addition, the clamping box B22 moves downwards to be spliced with the clamping box A21, at the moment, the base 35 drives the fixing clamp 39 to clamp the cable and clamp the vibration sensor on the cable, so that the cable and the closed environment in the area to be tested are fixed, high-quality detection conditions can be provided for the vibration sensor to work, and the detection result of the cable is improved; in addition, after the bearing seat 33 drives the push plate 25 to push the push block 26, the bearing seat 33 moves reversely along the reciprocating screw rod 32, when the cable is clamped by the fixing clamp 39, the position relation of the bearing seat 33 on the measuring plate 24 is observed, and the position of the vibration sensor positioned on the cable in the area to be measured can be calculated through the scales on the measuring plate 24, and the distance between the vibration sensor and the two ends of the cable in the area to be measured can be calculated, and the detection quality of the cable can be improved by detecting the cables in the area to be measured at a plurality of positions and comparing the position data;
in addition, when the bearing seat 33 moves, the bearing seat 33 drives the sealing rod 45 to move, the sealing rod 45 moves in the sealing cylinder 41, and the sealing rod 45 extrudes gas in the sealing cylinder 41 to be discharged through the blowing pipe 42, and as the air outlet of the blowing pipe 42 is positioned at one side of the cleaning clamp 37, the effect of cleaning impurities is achieved when the cleaning clamp 37 moves to clean a cable, and the effect of cleaning the cable can be improved by simultaneously carrying out two cleaning means;
in addition, when the bearing seat 33 moves reversely, the one-way valve 44 is arranged in the sealing cylinder 41, when the sealing rod 45 moves reversely, air cannot be pumped through the blowing pipe 42, only air can be pumped through the exhaust pipe 43, when the exhaust pipe 43 pumps air, the one-way valve 44 moves, and because the one-way valve 44 is positioned on one side of the cleaning clamp 37, the cleaning clamp 37 can be extruded when the one-way valve 44 moves, so that the cable is clamped by the cleaning clamp 37 and fixed, two ends of the cable in the area to be tested are clamped through the clamping box A21 and the clamping box B22, and the middle part of the cable in the area to be tested is fixedly clamped through the gear 27, so that the stability of the cable is greatly improved through fixing a plurality of places of the cable.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
