Description

Technical Field

[0001] The utility model relates to the field of optical fiber temperature measurement, and specifically relates to an optical fiber temperature measurement protection device. Background Art

[0002] Optical fiber sensors are essentially different from electric-based sensors. Optical fiber sensors use light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information, and are widely used due to their unique characteristics and are suitable for temperature measurement of high-voltage electrical appliances.

[0003] Among them, the publication (announcement) number: CN217819087, discloses an optical fiber temperature measurement probe protection device, including a fixed seat, multiple mounting bolts are provided on the fixed seat, a probe mounting protection tube is provided inside the fixed seat, a movable groove is opened inside the fixed seat, a connecting mechanism is provided inside the movable groove, the probe mounting protection tube includes a protection middle tube, a top cover and a bottom cover, fixed threads are provided on the inner walls at both ends of the protection middle tube, threaded plates are fixedly connected to the ends of the top cover and the bottom cover, a heat conduction sheet is fixedly connected to the bottom end of the bottom cover, and multiple elastic clamping blocks are fixedly connected inside the bottom cover.

[0004] In the above solution, the temperature measurement probe is placed inside the protection tube, and then the lower end of the protection tube is blocked by the heat conduction sheet. During the detection process, the heat is transferred to the temperature measurement probe through the heat conduction sheet for detection. However, since a small amount of heat loss will occur when the heat conduction sheet transfers heat, the temperature detected by the temperature measurement probe is not accurate enough. For this reason, an optical fiber temperature measurement protection device is proposed. Content of the Utility Model

[0015] 1. In the present utility model, through the provided protective shell, shell cover, moving ring, connecting rod and micro electric push rod, when temperature detection is required, an operator controls the micro electric push rod to work through the control system. The micro electric push rod extends to push the moving ring downward. At this time, the moving ring drives the temperature measuring probe to move downward. At the same time, the connecting rod and the shell cover move downward together and open the lower opening of the protective shell until the temperature measuring probe moves out of the interior of the protective shell. At this time, accurate temperature detection can be performed.

[0024] An embodiment of the present utility model discloses an optical fiber temperature measurement protection device.

[0025] The present utility model provides an optical fiber temperature measurement protection device as shown in Figure 1-2 The device includes a protective shell 1 and a temperature measurement probe 2. The lower end of the protective shell 1 is open, and a shell cover 3 is provided at the open end of the lower end of the protective shell 1. A moving ring 4 is slidably arranged inside the protective shell 1. The temperature measurement probe 2 is detachably installed inside the moving ring 4. Connecting rods 5 are fixedly arranged on both sides between the moving ring 4 and the shell cover 3. Micro electric push rods 6 are fixedly arranged on the inner walls of both sides of the protective shell 1. The moving end of the micro electric push rod 6 is fixedly connected to the moving ring 4. A wire 8 is arranged at the tail of the temperature measurement probe 2, and the wire 8 is hermetically passed through the upper end of the protective shell 1 and extends outwards. The micro electric push rod 6 is electrically connected to the control system of the temperature measurement probe 2, and the micro electric push rod 6 and the temperature measurement probe 2 can be controlled to work through the control system.

[0026] When it is necessary to detect the temperature, the control system controls the micro electric push rod 6 to work. The micro electric push rod 6 extends to push the moving ring 4 to move downwards. At this time, the moving ring 4 drives the temperature measurement probe 2 to move downwards. At the same time, the connecting rod 5 together with the shell cover 3 move downwards and open the open end of the lower end of the protective shell 1 until the temperature measurement probe 2 moves out of the protective shell 1. At this time, the temperature can be accurately detected. After the temperature measurement is completed, the micro electric push rod 6 is controlled to retract in the reverse direction, and the temperature measurement probe 2 can be received inside the protective shell 1 and the shell cover 3 can block the lower end of the protective shell 1, so as to provide better protection for the temperature measurement probe 2.

When it is necessary to disassemble the temperature measurement probe 2 from the inside of the protective shell 1, only need to loosen the positioning bolt 7 with a wrench so that the end of the positioning bolt 7 is separated from the temperature measurement probe 2, and thus the temperature measurement probe 2 can be taken out from the protective shell 1.

[0028] Finally, in order to provide better protection, as shown in Figure 1-2As shown, a rubber sealing ring 9 is fixedly provided at the edge of the upper surface of the shell cover 3, and the inner side wall of the protective shell 1 is in sliding contact with the rubber sealing ring 9.
