Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber temperature measurement, in particular to an intelligent optical fiber temperature measurement device. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". Optical fiber sensing technology is a new sensing technology that has developed along with the development of optical fiber and optical fiber communication technology. There are two main types of optical fiber sensing technology on the market. One is to use optical fiber directly as a sensor, and the other is a sensor based on grating. Optical fiber sensors are essentially different from electrical-based sensors. Optical fiber sensors use light as a carrier of sensitive information and optical fiber as a medium for transmitting sensitive information. They are widely used due to their unique characteristics.

[0003] In the patent entitled "An Intelligent Optical Fiber Temperature Measurement Device" with the Chinese publication number CN214407807U, the roller design enables the utility model to maintain a sliding effect when stuck on the cable. When the measurement of the measuring point is completed, the handle can be grasped to drive the utility model to slide, so as to reach the next measuring point. There is no need to disassemble and assemble again or even multiple times to complete the overall measurement, thereby reducing the difficulty of the measurement personnel's work, saving labor costs, further saving time, and improving work efficiency to a certain extent;

[0004] However, this device still has some shortcomings. In order to place the optical fiber between the card plates, the fixing plate needs to be manually moved to both sides to compress the first compression spring. Similarly, manual operation is also required to remove the device from the optical fiber, which directly affects the measurement efficiency. At the same time, the detection probe cannot be protected when it is used or not in use. The shaking of the probe is easy to collide with the casing of the temperature measuring device, thereby easily causing damage to the probe. In view of the above problems, the inventor proposes an intelligent optical fiber temperature measuring device to solve the above problems. Utility Model Content

A motor is fixedly installed near the center at one end of the bottom box away from the thermometer housing, and the output end of the motor passes through the thermometer housing and is fixedly connected to the screw.
