Technical Field

[0001] This utility model relates to the field of cable monitoring technology, specifically a wind turbine cable temperature monitoring device. Background Technology

[0002] A cable is an electrical energy or signal transmission device, typically composed of several or groups of conductors. Cables play an irreplaceable role in both daily life and national construction. In wind turbine units, cables are crucial components for current transmission and equipment connection. Unreliable contact at installation points or aging of the insulation layer at cable terminals can damage the cable's insulation performance, leading to safety hazards. Therefore, real-time monitoring of cable temperature is of paramount importance.

[0003] A search revealed a cable temperature monitoring device in patent document CN216309269U, comprising a first fixing sleeve and a second fixing sleeve. A controller is mounted on the left front end of the first fixing sleeve, a signal transmitter is mounted on the upper end of the controller, a display screen is mounted on the left front end of the controller, operation buttons are mounted on the right front end of the controller, and a detection device is mounted on the lower right end of the controller. Fixing devices are also mounted on the upper and lower ends of corresponding ends of both the first and second fixing sleeves. This cable temperature monitoring device, through the detection device, can not only display the cable temperature on the display screen but also transmit the signal to a user's mobile phone via the signal transmitter. Furthermore, the temperature sensor is detachable and replaceable, improving ease of use and installation. The fixing and clamping devices make the device compact and small, and easy to install and disassemble.

[0004] In the aforementioned prior art, the first and second fixing sleeves are connected by multiple fixing bolts and then clamped onto the outside of the cable. While this facilitates installation, it requires repeated tightening of the threaded components, affecting the installation speed. Therefore, a wind turbine cable temperature monitoring device is proposed to optimize the aforementioned prior art. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind turbine cable temperature monitoring device includes a first V-shaped clamp and a second V-shaped clamp symmetrically arranged on the outer side of the cable. The second V-shaped clamp is slidably connected to the inner side of a C-shaped component. An elastic mounting is provided between the second V-shaped clamp and the inner wall of the C-shaped component. Two baffles are symmetrically fixedly connected inward on the open side of the C-shaped component. The baffles are abutted against the two side edges of the first V-shaped clamp. Plugs are symmetrically fixedly connected to the baffles. Socket holes are provided on the first V-shaped clamp at the corresponding plug positions. A temperature measuring host is fixedly installed on the first V-shaped clamp.

[0010] As a further embodiment of this utility model: a spring is provided inside both the external threaded sleeve and the extension sleeve, and abutment plates are fixedly connected to both ends of the spring. The abutment plates are in contact with and slide against the inner walls of the ends of the external threaded sleeve and the extension sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The device of this utility model is installed on the outside of the cable by clamping it with the first V-shaped clamp and the second V-shaped clamp, so that it can be used to accommodate cables of different diameters when the first V-shaped clamp and the second V-shaped clamp are different.

[0015] 2. The second V-shaped clamp of this utility model is installed inside the C-shaped part. The first V-shaped clamp is connected to the C-shaped part through the cooperation of the flange, plug and socket. Under the elastic support of the second V-shaped clamp and the C-shaped part, a reverse tension effect is formed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3In this embodiment of the present invention, a wind turbine cable temperature monitoring device includes a first V-shaped clamp 1 and a second V-shaped clamp 2 symmetrically arranged on the outer side of the cable. The second V-shaped clamp 2 is slidably connected to the inner side of a C-shaped component 3. An elastic installation is provided between the second V-shaped clamp 2 and the inner wall of the C-shaped component 3. Two baffles 4 are symmetrically fixedly connected inward on the opening side of the C-shaped component 3. The baffles 4 are attached to the two side edges of the first V-shaped clamp 1. Plugs 5 are symmetrically fixedly connected to each baffle 4. A socket 6 is provided on the first V-shaped clamp 1 corresponding to the plug 5. A temperature measuring host 7 is fixedly installed on the first V-shaped clamp 1. A temperature sensor 8 is provided on the outer side of the temperature measuring host 7. The temperature sensor 8 extends to the inner side of the first V-shaped clamp 1.

[0024] The entire device is clamped and installed on the outside of the cable by the first V-shaped clamp 1 and the second V-shaped clamp 2, so that it can be used to accommodate cables of different diameters when the first V-shaped clamp 1 and the second V-shaped clamp 2 are different.

[0025] The second V-shaped clamp 2 is installed inside the C-shaped part 3. The first V-shaped clamp 1 is connected to the C-shaped part 3 through the cooperation of the flange 4, the plug 5 and the socket 6. Thus, under the elastic support force of the second V-shaped clamp 2 and the C-shaped part 3, a reverse tension effect is formed. In this way, the first V-shaped clamp 1 and the second V-shaped clamp 2 can be clamped on both sides of the cable. They can be directly fixed and combined without rotating the threaded parts, making the installation and assembly more convenient and quick.

[0026] The top and bottom of the C-shaped part 3 are provided with sliding grooves 9, and sliding blocks 10 adapted to it are slidably connected in the sliding grooves 9. The sliding blocks 10 are respectively fixedly connected to both ends of the second V-shaped clamp 2.

[0027] The C-shaped part 3 has an external threaded sleeve 11 that is threaded through the middle at equal intervals. An extension sleeve 12 that is adapted to the external threaded sleeve 11 is movably inserted into the inner side of the external threaded sleeve 11. The extension sleeve 12 is fixedly connected to the second V-shaped clamp 2.

[0028] The external threaded sleeve 11 and the extension sleeve 12 are both provided with a spring 13. Both ends of the spring 13 are fixedly connected with abutment pieces 14. The abutment pieces 14 are in contact with and slide against the inner walls of the ends of the external threaded sleeve 11 and the extension sleeve 12. The external threaded sleeve 11 is provided with a rotating part on the outside.

[0029] The external threaded sleeve 11 is threadedly installed with the C-shaped part 3, so that the rotation of the external threaded sleeve 11 can compress the spring 13, control the elastic preload of the second V-shaped clamp 2 and the C-shaped part 3, and facilitate the control of the clamping force for cables of different thicknesses.

[0030] The first V-shaped clamp 1 is fixedly connected to the temperature sensor 8 through the insertion sleeve 15. The insertion sleeve 15 is damped and inserted with an extension tube 16 that is adapted to it. The temperature sensor 8 is fixedly connected to the end of the extension tube 16. The insertion sleeve 15 is provided with an anti-slip rubber sleeve, which clamps the extension tube 16 to form a damping sliding effect. The extension tube 16 can be used to run the connecting wire of the temperature sensor 8.

[0031] The extension fitting 16 is damped and inserted into the sleeve 15, thereby facilitating contact between the temperature sensor 8 and the cable surface clamped in the first V-shaped clamp 1.

[0032] The temperature measuring host 7 is equipped with a display screen 17, setting buttons 18, and warning lights 19. The warning lights 19 have three colors: green, yellow, and red. The temperature measuring host 7 contains a main control chip and a communication module. The main control chip can be an ESP32, and the temperature sensor 8 can be a DS18B20. The display screen 17 can be a 0.96" OLED (128x64 pixels). The setting buttons 18 have three buttons: set, increase, and decrease. The warning lights 19 are RGB LED alarm indicators. The temperature measuring host 7 has a built-in power supply and is equipped with a power charging port and a direct connection port. The green light indicates that the cable temperature is within the normal range; the yellow light indicates a rapid change in cable temperature (preset temperature change rate 1℃ / min, duration 3min); and the red light indicates that the cable surface temperature exceeds a preset temperature (70℃). The temperature sensor 8 is electrically connected to the temperature measuring host 7.

[0033] The working principle of this utility model is as follows:

[0034] In use, the C-shaped piece 3 is fastened to one side of the cable, and the second V-shaped clamp 2 is pressed, causing the retaining edge 4 to extend forward. At this time, the first V-shaped clamp 1 is inserted from one side of the C-shaped piece 3, so that the plug 5 corresponds to the socket 6. The C-shaped piece 3 is released, and with the cooperation of the external threaded sleeve 11, the extension sleeve 12 and the spring 13, a reverse tension is formed, so that the first V-shaped clamp 1 and the second V-shaped clamp 2 are clamped on the outside of the cable. At this time, the extension tube 16 is inserted further inward through the insertion sleeve 15, so that the temperature sensor 8 is pressed against the outer surface of the cable. At this time, the preset temperature change is 1℃ / min, the duration is 3min, and the preset limit temperature is 70℃, thereby monitoring the surface temperature of the cable.

[0035] Before use, rotate the external threaded sleeve 11 according to the cable being used to control the effective compression of the spring 13, thereby facilitating the clamping and pre-tightening of cables of different diameters.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
