[0014] 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.
[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] Reference Figure 1 and 3 A cable body temperature monitoring device includes a bracket 1 for fixing the cable. The bracket 1 is mirror-arranged with two sets for supporting and fixing both ends of the cable device being monitored. A terminal 2 is fixedly installed on the top of each of the two sets of brackets 1, and the cable body 3 is fixedly installed inside the terminal 2.
[0017] Reference Figure 2 and 4 A temperature sensing component is provided on the cable body 3 for real-time temperature monitoring of the cable body 3. A temperature sensing tape 41 is wound around the cable body 3 in a coil. The temperature sensing tape 41 is a strip that can be twisted at will. It has deformability and adhesion. In an area where temperature monitoring of the cable body 3 is required, the temperature sensing tape 41 is wrapped around the outer circumference of the cable body 3. The shape of the temperature sensing tape 41 is more material-saving than wrapping the entire cable body 3, and the distribution is more uniform.
[0018] One side of the temperature sensing band 41 is provided with a thermally sensitive area 42. The thermally sensitive area 42 is mainly used to sense the temperature change on the cable body 3 and to present the temperature information intuitively through color change so that the operator can quickly understand the temperature status of the cable body 3. Both ends of the temperature sensing band 41 are provided with connecting ends 43 for fixing the temperature sensing band 41 after it is wrapped around the surface of the cable body 3.
[0019] The thermally sensitive area 42 has the following characteristics: by being attached to the surface of the cable body 3, it will transfer the temperature to the temperature sensing band 41 after the internal temperature of the cable body 3 changes. In the initial state, the thermally sensitive area 42 on the temperature sensing band 41 is white. When the temperature of the thermally sensitive area 42 exceeds a certain threshold, the color of the thermally sensitive area 42 will change, such as to red, to indicate the temperature. Moreover, the color change of the thermally sensitive area 42 is reversible and will change in real time with the current temperature. When the temperature drops but does not exceed the set threshold, it will return to the initial state.
[0020] Reference Figure 2 and 3 The bracket 1 is equipped with an auxiliary component 5 for fixing the temperature sensing band 41. The auxiliary component 5 includes an electric push rod 51. The electric push rod 51 is fixedly installed on the side wall of the bracket 1. The piston end of the electric push rod 51 passes through the inside of the bracket 1 and is fixedly connected to a movable rod 52. The other end of the movable rod 52 is fixedly connected to a hook 53. The hook 53 cooperates with a lifting ring 54. The lifting ring 54 is fixedly set at one end of the connection end 43 of the temperature sensing band 41, and both ends of the connection end 43 of the temperature sensing band 41 are connected to the lifting ring 54. The electric push rod 51 can drive the hook 53 to move horizontally through an internal motor. When the hook 53 cooperates with the lifting ring 54, its horizontal movement will control the tightness of the temperature sensing band 41. When the two sets of hooks 53 approach the electric push rod 51 at the same time, the two sets of hooks 53 pull the lifting ring 54, so that the two ends of the temperature sensing band 41 are gradually tightened, so that the temperature sensing band 41 can better fit the surface of the cable body 3, and play a role in fixing and tightening the temperature sensing band 41.
[0021] Reference Figure 1 and 2 The cable body temperature monitoring equipment in operation involves wrapping the temperature sensing strip 41 around the cable body 3 and fixing the temperature sensing strip 41 to the hook 53 via an electric push rod 51. A monitoring device 6 is set around the cable body 3. The monitoring device 6 can be a camera used to monitor the current cable body 3 and the temperature sensing strip 41. The monitoring device 6 has an image acquisition function and can monitor the color change caused by the temperature change of the heat-sensitive area 42 in real time. When the monitoring device 6 detects that the color of the heat-sensitive area 42 changes due to the temperature exceeding the threshold, it will issue a protection reminder to the monitoring department. The camera range of the monitoring device 6 is fan-shaped, and it acquires images of the cable body 3 with the temperature sensing strip 41 installed. In large-scale power application scenarios, the temperature monitoring equipment can be set at certain intervals for the long cable body 3 to monitor the temperature of the cable body 3 in different sections.
[0022] The specific working principle of this utility model is as follows: Two sets of mirror-arranged brackets 1 support and fix the two ends of the cable equipment respectively. The terminal 2 at the top of the bracket 1 is used to fix the cable body 3. The temperature sensing tape 41 is rolled up and can be flexibly wrapped around the area of the cable body 3 that needs to be monitored. When the wrapping is completed and the temperature sensing tape 41 needs to be fixed, the hanging ring 54 on the temperature sensing tape 41 is hooked onto the hook 53. The electric push rod 51 drives the hook 53 to move horizontally. When both sets of hooks 53 approach the electric push rod 51 at the same time, the hanging ring 54 is pulled to tighten both ends of the temperature sensing tape 41, so that it fits tightly against the surface of the cable body 3, thus achieving fixation. When it needs to be removed, the operation is reversed. The temperature sensing tape 41 itself has deformability and adhesion, which allows it to evenly distribute the temperature monitoring. One side of the temperature sensing tape 41 is provided with a heat-sensitive area 42. Initially white, the heat-sensitive zone 42 is transferred to the temperature-sensitive zone 41 when the internal temperature of the cable body 3 changes. Once the temperature exceeds the set threshold, the color of the heat-sensitive zone 42 turns red, visually indicating an abnormal cable temperature. The color of the heat-sensitive zone 42 changes in real time with the temperature. When the temperature drops below the threshold, it returns to its initial white state, thus continuously feeding back the cable temperature changes. A monitoring device 6 is installed around the cable body 3. Its camera range is fan-shaped, which can collect images of the cable body 3 with the temperature-sensitive zone 41 installed. It can capture the color change of the heat-sensitive zone 42 in real time due to temperature changes. When the monitoring device 6 detects that the color of the heat-sensitive zone 42 turns red, it determines that the cable temperature exceeds the threshold and sends an alarm signal to the monitoring department so that maintenance personnel can deal with it in time and avoid cable failure due to overheating.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
