[0031] A temperature acquisition and early warning device for wind power cable joints, its structure is as follows: Figures 1-5 As shown, the system includes a mounting box 100, which is installed on the outside of the wind power cable joint for temperature acquisition and overheat warning of the wind power cable joint; two temperature sensors 200, each a fiber optic grating temperature sensor, are mounted side-by-side and correspondingly snapped onto corresponding fixing mechanisms 300, so that the temperature sensors 200 mounted on the fixing mechanisms 300 abut against the wind power cable joint to collect the temperature at the wind power cable joint; and two fixing mechanisms 300 are mounted side-by-side and correspondingly movably on the upper housing 110 and lower housing 120 of the mounting box 100, so that the two corresponding fixing mechanisms 300 fix the temperature sensors 200 against the wind power cable joint. This replaces the original infrared temperature detector installed on the outside of the joint, thereby improving the accuracy of wind power cable joint temperature acquisition; a voice warning device 400, installed on the top of the upper box 110 of the fixed box 100, is connected to the warning module, and emits an alarm sound when the temperature at the wind power cable joint is too high, so that the inspection personnel can promptly inspect and repair the wind power cable joint with potential safety hazards; several light indicators 500 are installed side by side and at intervals on the top of the upper box 110, so that the light indicators 500 emit different colored lights, thereby providing light warning of the temperature at the wind power cable joint, so that the inspection personnel can promptly discover cable joints with potential safety hazards.

[0032] As a preferred embodiment, please refer to Figure 3 The fixing box 100 includes an upper box body 110 and a lower box body 120.

At the same time, the upper box body 110 is provided with a number of positioning rods 111, and the lower box body 120 is provided with a number of corresponding positioning grooves 121, so that each positioning rod 111 is engaged in the corresponding positioning groove 121, thereby positioning and connecting the upper box body 110 and the lower box body 120, thereby improving the accuracy of temperature acquisition and early warning of the wind power cable joint by the temperature acquisition and early warning device.

[0033] As a preferred embodiment, please refer to Figure 4 and Figure 5 The fixing mechanism 300 includes a fixing plate 310, several moving rods 320, and several elastic elements 330. The moving rods 320 are arranged side by side and spaced apart at the bottom of the fixing plate 310. The moving rods 320 are movably installed in corresponding moving slots 140 of the fixing box 100, and each moving slot 140 is equipped with a corresponding elastic element 330 so that each moving rod 320 abuts against the corresponding elastic element 330. When the fixing plate 310 abuts against the joints of wind power cables of different diameters, the wind power cable joints of different diameters push the moving rods 320 connected to the fixing plate 310 to move along the moving slots 140 on the fixing box 100, thereby pushing the metal spring of the elastic element 330 abutting against the moving rods 320 to compress. The elastic potential energy generated after the metal spring of the elastic element 330 is compressed pushes the probe 210 connected to the fixing plate 310 to abut against the outside of the wind power cable joint of different diameters, thereby improving the accuracy of temperature acquisition and early warning of wind power cable joints by the temperature acquisition and early warning device.

[0034] As a preferred embodiment, please refer to Figure 4 The fixing plate 310 has an arc-shaped structure and a snap-fit ​​groove 311. The probe 210 on the temperature acquisition device 200 is snapped into the snap-fit ​​groove 311, thereby improving the installation efficiency of the temperature acquisition device 200. A connecting wire is also installed on the side of the probe 210. The connecting wire is electrically connected to the temperature acquisition module installed on the upper box 110, so that the temperature of the wind power cable joint collected by the probe 210 can be transmitted to the temperature acquisition module in a timely manner. The temperature data received by the temperature acquisition module can then be transmitted to the controller to monitor and warn of the temperature of the wind power cable joint in a timely manner.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 2 The upper box 110 and the lower box 120 are also provided with corresponding connecting plates 130 on both sides.

[0038] The working principle of this utility model for temperature acquisition and early warning device for wind power cable joints is as follows:

[0039] Construction workers install the fixing box 100 on the outside of the wind power cable joint, so that the upper box body 110 and lower box body 120 of the hinged fixing box 100 wrap around the cable joint. This allows the fixing plates 310 on the two fixing mechanisms 300 installed inside the fixing box 100 to abut against the outside of wind power cable joints of different diameters. The wind power cable joints of different diameters push several moving rods 320 connected to the fixing plates 310 to move along several moving slots 140 on the fixing box 100, thereby compressing the elastic element 330 metal springs that the moving rods 320 abut against. The elastic potential energy generated by the compressed elastic element 330 metal springs pushes the fixing plate 310 against the outside of the wind power cable joints of different diameters, thus causing the corresponding temperature acquisition device 200 probe 210, which is engaged in the locking slot 311 of the fixing plate 310, to engage with the wind... The power cable joint is abutted to allow the two temperature acquisition devices 200 to collect the temperature at the wind power cable joint in real time, thereby obtaining temperature data information at the wind power cable joint in a timely manner and improving the safety of the wind power cable joint. After the upper box 110 and the lower box 120 are snapped together, the fixing straps pass through the corresponding fixing rings 131 on the two connecting plates 130 and fix the fixing box 100 to the outside of the wind power cable joint. At the same time, the top of the fixing box 100 is equipped with a voice warning device 400 and several light indicators 500. The voice warning device 400 will sound an alarm when the temperature of the wind power cable joint exceeds the set temperature, so that the inspection personnel can discover safety hazards in time. At the same time, the several light indicators 500 will display different colored lights, so that the inspection personnel can discover safety hazards in time and improve the safety of the wind power cable joint.
