[0045] One end of the mounting frame 602 is mounted with a detection component 8. The detection component 8 includes a fixing frame 801, a laser lamp 802, a light receiver 803 and an induction sensor 804;

[0046] One end of the mounting frame 602 is mounted with a fixing frame 801. The optical fiber 4 passes through the inside of the fixing frame 801. The optical fiber 4 is between the two rollers 612, facilitating the guiding of the optical fiber 4 and facilitating the detection and processing of the optical fiber 4. A laser lamp 802 is disposed on the inner top surface of the fixing frame 801. A light receiver 803 is disposed on the inner bottom surface of the fixing frame 801. Induction sensors 804 are mounted at both ends inside the fixing frame 801.

[0047] The top of the mounting frame 602 is mounted with a multi - cleaning component 9. The multi - cleaning component 9 includes a cam 901, a fixing box 902, a pushing spring 903, a driving rod 904, a moving rod 905, a sliding plate 906, a connecting pipe 907, an air outlet ring 908, a mounting ring 909 and a cleaning cotton 910;

[0048] A cam 901 is fixedly sleeved outside the driving shaft 607. One end of the top surface of the mounting frame 602 is fixedly installed with a fixed box 902. One end inside the fixed box 902 is welded with a pushing spring 903. One end of the pushing spring 903 is welded with a driving rod 904. Arc angles are provided at the ends of the cam 901 and the driving rod 904. The cam 901 and the driving rod 904 are in contact with each other to facilitate the movement of the driving rod 904. One end of the driving rod 904 is installed with a moving rod 905 through a screw. One end of the moving rod 905 is installed with a sliding plate 906 through a screw. The sliding plate 906 is inside the fixed box 902. A rubber frame is adhered to the outside of the sliding plate 906, which can compress the gas inside the fixed box 902 so that the gas is ejected from the air outlet ring 908. Both ends of the fixed box 902 are fixedly connected with connecting pipes 907. One end of the connecting pipe 907 is fixedly connected with an air outlet ring 908. One end of the mounting plate 611 is installed with a mounting ring 909 through a screw. A cleaning cotton 910 is adhered inside the mounting ring 909. The optical fiber 4 is inside the cleaning cotton 910. The air outlet ring 908 is outside the optical fiber 4. A plurality of air outlets are evenly arranged on the outside of the air outlet ring 908 to facilitate the cleaning of the outside of the optical fiber 4.

[0049] When a person needs to use the measuring device to measure humidity, after placing the optical fiber sensor substrate 1 in a suitable position, the person then pulls one end of the optical fiber 4 to make the winding roller 3 rotate, moves the detection head 5 to the designated position and fixes it, connects the other end of the optical fiber 4 to the optical fiber sensor substrate 1, and then detects the air humidity through the detection head 5 and displays the humidity through the optical fiber sensor substrate 1 to achieve the detection of air humidity. During the use of the device, the cooling fan 2 is turned on to dissipate heat from the device to avoid the problem that the high temperature during the use of the device affects the use of the device. 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;

[0050] When the take-up roller 3 rotates, it drives the second gear 604 and the driving shaft 607 to rotate. Through the rotation of the driving shaft 607, the belt connection mechanism 608 is driven to rotate, and then the reciprocating lead screw 609 is driven to rotate. Through the rotation of the reciprocating lead screw 609, the moving block 610 moves back and forth. Through the back-and-forth movement of the moving block 610, the uniform winding and unwinding of the optical fiber 4 are realized, avoiding the problem that the optical fiber 4 is broken due to winding during the winding and unwinding process, which affects the humidity measurement. And during the winding and unwinding process, the optical fiber 4 is guided by the roller 612 to ensure the stability of the optical fiber 4 during the winding and unwinding process. When the personnel wind and unwind the optical fiber 4, the movement of the optical fiber 4 drives the roller 612 to rotate. When the pulling speed of the optical fiber 4 is too fast, the rotation speed of the roller 612 increases. At this time, due to the action of centrifugal force, the rotation of the roller 612 drives the rotating plate 708 to rotate, causing the return spring 709 to stretch, so that the rotating plate 708 contacts the fixed plate 706, fixing the roller 612 so that the roller 612 does not rotate. At this time, the movement of the optical fiber 4 will drive the roller 612 to move. At this time, the spring damper 701 buffers the roller 612 and the optical fiber 4, and the alarm switch 703 contacts the mounting block 702, turning on the alarm light 704 to remind the personnel, avoiding the problem that the personnel's rapid pulling damages the optical fiber 4. When the personnel reduce the pulling speed of the optical fiber 4, the speed of the roller 612 decreases at this time, and the return spring 709 resets, 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, realizing the movement of the optical fiber 4;

[0051] During the movement of the optical fiber 4, the optical fiber 4 is sensed by the induction sensor 804. When the induction sensor 804 senses the optical fiber 4, the laser lamp 802 is turned on at this time, so that the laser lamp 802 irradiates the optical fiber 4. At this time, the light receiver 803 senses the light of the laser lamp 802. When the light receiver 803 receives the light of the laser lamp 802, the optical fiber 4 is intact at this time. When the light receiver 803 does not receive the light of the laser lamp 802, the optical fiber 4 is damaged at this time. Therefore, the optical fiber 4 can be detected during the winding and unwinding of the optical fiber 4, ensuring the use of the humidity measurement device;

[0052] When the driving shaft 607 rotates, it drives the cam 901 to rotate, so that the cam 901 continuously contacts the driving rod 904, causing the pushing spring 903 to stretch and compress continuously. Then the driving rod 904 and the sliding plate 906 are driven to move, so that the gas inside the fixed box 902 is ejected through the connecting pipe 907 by the air outlet ring 908 to blow and clean the outside of the optical fiber 4. And the optical fiber 4 passes through the cleaning cotton 910 to perform secondary cleaning on the surface of the optical fiber 4, improving the cleaning effect of the surface of the optical fiber 4, and avoiding the problem that impurities such as dust and oil on the outside of the optical fiber 4 will reduce the transmission efficiency of the optical signal and affect the data transmission quality;

[0053] When the device is not needed, the operator moves the mounting frame 602 to move the first gear 603 to the outside of the drive shaft 605. Then the operator fixes the manual adjusting rod 601, and further fixes the mounting frame 602. The rotation of the output shaft of the cooling fan 2 drives the drive shaft 605 to rotate, which in turn drives the first gear 603 to rotate. Through the meshing connection between the first gear 603 and the second gear 604, the second gear 604 is driven to rotate. The rotation of the second gear 604 drives the winding roller 3 to wind the optical fiber 4. During the winding process of the optical fiber 4, through the connection of the belt connection mechanism 608, the reciprocating screw rod 609 can be driven to rotate, realizing the reciprocating movement of the moving block 610, and thus realizing the uniform winding of the optical fiber 4, which is convenient for the next use of the optical fiber 4. And during the winding process, the surface of the optical fiber 4 can be cleaned to avoid the problem that impurities outside the optical fiber 4 cause damage to the optical fiber 4 during the winding process of the optical fiber 4, ensuring the use of the device, and there is no need for the operator to wind manually, improving the convenience of the device during use.
