At present, wind power generation has grown into the main force of renewable energy generation in my country. At the same time, my country's wind power industry has been in a rapid development stage, and the existing new installed capacity and cumulative installed capacity are both in the world's leading position; and among the supporting facilities of wind turbines, wind turbine towers play a vital role.

[0003] With the use of power supply and distribution equipment in wind turbine towers, defects in high-voltage cables themselves or due to problems in the manufacturing process, the high-voltage cables are subjected to heavy loads for a long time, and the hidden defects inside gradually deteriorate. If the operation and maintenance personnel fail to find them in time, it will eventually cause safety hazards, and even power outages, fires, explosions and other serious accidents. Therefore, timely discovery of power supply and distribution cable degradation and timely discovery and elimination of hidden dangers are the key to preventing power supply and distribution accidents.

[0004] However, the existing cable temperature detection is mostly a sleeve-like structure that is ringed on the outside of the cable. Although the ring structure has high detection accuracy, its wrapping effect will affect the cable's own heat dissipation performance, causing the actual working temperature of the cable to be different from the detection temperature, affecting the detection result. Therefore, the present application provides a power cable temperature detection device for wind power generation to meet the needs. Utility Model Content

[0009] Preferably, the opening end of the hook faces upward.

[0010] Preferably, a slide rail is provided on the top of the machine box, which is composed of two plates with L-shaped cross-sections arranged opposite to each other, and one end of the slide rail is closed.

[0011] Preferably, a slider is provided at the bottom of the thermometer, the cross-section of the slider is I-shaped, and the slider is slidably connected with the slide rail.

DETAILED DESCRIPTION

[0020] The following is a detailed description of a power cable temperature detection device for wind power generation provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods for implementation; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0021] like Figure 1 - Figure 2 As shown, an embodiment of the utility model provides a power cable temperature detection device for wind power generation, comprising a machine box 1, a hook 3 is provided on one side of the machine box 1, a cable 5 is clamped on the hook 3, a thermometer 2 is provided on the top of the machine box 1, the thermometer (2) is an infrared thermometer, the thermometer 2 is electrically connected to the machine box 1 through an electric wire 4, and the thermometer 2 is set so that the probe is facing the cable 5 when measuring the temperature.

[0022] The cable 5 is fixed by setting a hook 3, and the temperature of the cable 5 is measured by the thermometer 2. The fixing method is open, which will not affect the local heat dissipation performance of the cable itself, thereby ensuring the accuracy of the temperature measurement data. At the same time, the installation method of the temperature measuring device is simple, and no other tools are required, thereby improving the installation efficiency.

[0023] like Figure 1 As shown, two hooks 3 are provided, and the two hooks 3 are located at the bottom of the same side of the machine box 1 and are distributed parallel to each other; the opening end of the hook 3 faces upward.

[0024] With this arrangement, after the cable 5 is clamped, the cable 5 and the side of the housing 1 are parallel to each other, thereby ensuring that the probe of the thermometer 2 faces the surface of the cable 5 .

[0025] like Figure 2 As shown, a slide rail 6 is provided on the top of the machine box 1, which is composed of two plates with L-shaped cross-sections arranged opposite to each other, and one end of the slide rail 6 is closed.

[0026] The slide rail 6 is composed of two plates with L-shaped cross-sections, and the internal slide groove of the slide rail 6 presents a T-shaped structure. By closing one end thereof, and the closed end is the end close to the hook 3, the calibration of the irradiation area of ​​the thermometer 2 can be directly completed when the thermometer 2 slides to the innermost end of the slide rail 6 during installation, thereby improving the installation speed and accelerating the layout efficiency.

[0027] like Figure 2 As shown, a slider 7 is provided at the bottom of the thermometer 2 , the cross-section of the slider 7 is in an I-shape, and the slider 7 is slidably connected with the slide rail 6 .

[0028] The sliding connection between the slider 7 and the slide rail 6 is tightly matched, thereby ensuring the structural stability of the thermometer 2 during installation and preventing the loosening of the two from causing the irradiation point of the port of the thermometer 2 to shift.

[0029] In a further embodiment, based on the above scheme, the machine box 1 is connected to an external power supply and powers the thermometer 2 through the wire 4, wherein the machine box 1 includes a main control board, and the main control board is connected to the client through a wireless or wired network. The client sends a signal to the main control board to control the thermometer 2 to start and measure the surface temperature of the cable 5 at this time. The measured temperature data is transmitted to the main control board via the wire 4, and further transmitted to the client through the network connection to complete a single measurement of the temperature of the cable 5.

[0030] The technical solution provided by the utility model is that when installing the temperature measuring device, the cable 5 is first lifted and the position of the machine box 1 is adjusted so that the hook 3 is under the cable 5, and then the cable 5 is lowered so that the cable 5 falls into the hook 3 and is clamped. At this time, it is ensured that the line of the cable 5 located in the middle section of the two hooks 3 is in a straight line. Subsequently, the thermometer 2 is slid into the innermost end of the slide rail 6 through the slider 7, and it is checked whether the irradiation point of the end of the thermometer 2 is located on the cable 5. If there is a deviation, the sliding adjustment slider 7 is slid to adjust the sliding insertion depth. After verification, the wire 4 is connected between the machine box 1 and the thermometer 2 to complete the installation of the equipment.

[0031] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
