[0023] A multiple cleaning assembly 9 is installed on the top of the installation frame 602, and the multiple cleaning assembly 9 includes a cam 901, a fixing box 902, a push spring 903, a driving rod 904, a moving rod 905, a slide plate 906, a connecting pipe 907, an air outlet ring 908, a mounting ring 909 and cleaning cotton 910; A cam 901 is fixedly sleeved on the outer side of the driving shaft 607, a fixed box 902 is fixedly installed on one end of the top surface of the installation frame 602, a push spring 903 is welded on one end of the fixed box 902, a driving rod 904 is welded on one end of the push spring 903, and arc angles are provided at the ends of the cam 901 and the driving rod 904, and the cam 901 and the driving rod 904 are in contact with each other, which is convenient for pushing the driving rod 904 to move, a moving rod 905 is installed on one end of the driving rod 904 through a screw, and a slide plate 906 is installed on one end of the moving rod 905 through a screw, and the slide plate 906 is in the fixed box 90 2, a rubber frame is bonded to the outside of the slide plate 906, which can compress the gas inside the fixed box 902 so that the gas is ejected from the air outlet circle 908. Both ends of the fixed box 902 are fixedly connected with connecting pipes 907, and one end of the connecting pipe 907 is fixedly connected with the air outlet circle 908. One end of the mounting plate 611 is fixedly installed with a mounting ring 909 by screws, and a cleaning cotton 910 is bonded inside the mounting ring 909. The optical fiber 4 is inside the cleaning cotton 910, and the air outlet circle 908 is outside the optical fiber 4. A plurality of air outlets are evenly opened outside the air outlet circle 908 to facilitate cleaning of the outside of the optical fiber 4.

[0024] When personnel need to use the measuring device to measure humidity, they first place the optical fiber sensor base 1 in a suitable position, then pull one end of the optical fiber 4 to rotate the winding roller 3, move the detection head 5 to a specified position and fix it, connect the other end of the optical fiber 4 to the optical fiber sensor base 1, then detect the air humidity through the detection head 5, and display the humidity through the optical fiber sensor base 1 to achieve the detection of air humidity. During the use of the device, the cooling fan 2 is turned on to dissipate the heat of the device to avoid the problem of high temperature affecting the use of the device when the device is in use. During the use of the cooling fan 2, the first gear 603 is not inside the driving shaft 605, so the first gear 603 will not be driven to rotate when the cooling fan 2 is in use. When the winding roller 3 rotates, it drives the second gear 604 and the driving shaft 607 to rotate, and the rotation of the driving shaft 607 drives the belt connecting mechanism 608 to rotate, and then drives the reciprocating screw rod 609 to rotate, and the rotation of the reciprocating screw rod 609 drives the moving block 610 to move back and forth. The moving block 610 moves back and forth to achieve uniform retraction and release of the optical fiber 4, thereby avoiding the problem of the optical fiber 4 being entangled and broken during the retraction and release process, which affects the humidity measurement. In the retraction and release process, the optical fiber 4 is guided by the roller 612 to ensure the stability of the optical fiber 4 during the retraction and release process. When personnel are retracting and releasing the optical fiber 4, the movement of the optical fiber 4 drives the roller 612 to rotate. When the optical fiber 4 is pulled too fast, the rotation speed of the roller 612 is accelerated. At this time, due to the effect of centrifugal force, the roller 6 12 rotation drives the rotating plate 708 to rotate, so that the reset spring 709 is stretched, so that the rotating plate 708 contacts the fixed plate 706, and the roller 612 is fixed so that the roller 612 does not rotate. At this time, the movement of the optical fiber 4 drives the roller 612 to move. At this time, the roller 612 and the optical fiber 4 are buffered by the spring damper 701, and the alarm switch 703 contacts the mounting block 702, and the alarm light 704 is turned on to remind the personnel to avoid the problem of damage to the optical fiber 4 caused by the personnel pulling quickly. When the personnel reduce the speed of pulling the optical fiber 4, the speed of the roller 612 is reduced, and the reset spring 709 is reset, driving the rotating plate 708 to rotate, so that the rotating plate 708 does not contact the fixed plate 706. At this time, the roller 612 resumes rotation to realize the movement of the optical fiber 4; During the movement of the optical fiber 4, the optical fiber 4 is sensed by the inductive sensor 804. When the inductive sensor 804 senses the optical fiber 4, the laser light 802 is turned on, so that the laser light 802 irradiates the optical fiber 4. At this time, the light receiver 803 senses the light of the laser light 802. When the light receiver 803 receives the light of the laser light 802, the optical fiber 4 is intact. When the light receiver 803 does not receive the light of the laser light 802, the optical fiber 4 is damaged. Then, the optical fiber 4 can be detected when the optical fiber 4 is retracted and released to ensure the use of the humidity measuring device. When the driving shaft 607 rotates, the cam 901 is driven to rotate, so that the cam 901 is constantly in contact with the driving rod 904, so that the push spring 903 is constantly stretched and compressed, and then the driving rod 904 and the slide plate 906 are driven to move, so that the gas inside the fixed box 902 is ejected through the connecting pipe 907 and the air outlet ring 908, and the outside of the optical fiber 4 is blown and cleaned, and the optical fiber 4 passes through the cleaning cotton 910, and the surface of the optical fiber 4 is cleaned twice, so as to improve the cleaning effect of the surface of the optical fiber 4, and avoid the dust, oil and other impurities on the outside of the optical fiber 4 that reduce the transmission efficiency of the optical signal and affect the data transmission quality. When the device is not needed, the personnel moves the first gear 603 to the outside of the driving shaft 605 by moving the installation frame 602, and then fixes the manual adjustment rod 601, and then fixes the installation frame 602. The driving shaft 605 is driven to rotate by the rotation of the output shaft of the cooling fan 2, and then the first gear 603 is driven to rotate. The meshing connection between the first gear 603 and the second gear 604 drives the second gear 604 to rotate. The rotation of the second gear 604 drives the winding roller 3 to rotate to wind the optical fiber 4. During the winding process of the optical fiber 4, the reciprocating screw rod 609 can be driven to rotate through the connection of the belt connection mechanism 608 to realize the reciprocating movement of the moving block 610, thereby realizing uniform winding of the optical fiber 4, which is convenient for the next use of the optical fiber 4. In the winding process, the surface of the optical fiber 4 can be cleaned to avoid the problem of impurities on the outside of the optical fiber 4 causing damage to the optical fiber 4 during the winding process, thereby ensuring the use of the device, and no manual winding is required, thereby improving the convenience of the device when used.
