Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a clamping mechanism and a line testing device. Background Technology

[0002] Online temperature monitoring devices for power lines are mainly used for real-time temperature monitoring at the connection points between clamps and conductors in power systems to prevent overheating faults caused by poor contact, overload, or environmental factors. However, conventional technical applications rely on manual inspections or fixed sensors, which presents many inconveniences.

[0003] Conventional cable clamps use bolts to tighten wires, requiring tools for installation, making quick adjustments impossible, and they have poor compatibility with cables of different diameters. Sensors are directly fixed in a specific position, making them unsuitable for different cable angles or diameters, resulting in poor flexibility. When there is an angle difference between the cable position and the fixed position, conventional cable clamps cannot handle complex angle differences, leading to cumbersome and difficult wiring.

[0004] Therefore, there is a need for a clamping mechanism and line detection device that can effectively adapt to cables of different diameters, adjust quickly, not easily loosen, adapt to different angles of clamp installation, and simultaneously link with sensors to tightly fit the cable under test, providing higher detection accuracy to meet the needs of the current environment. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that conventional wire clamps in the existing environment use bolts to tighten wires, require tools for installation, cannot be quickly adjusted, and have poor compatibility with cables of different diameters.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] The wire assembly includes a guide frame and an adjustment hole fixedly formed on the top of the guide frame;

[0009] The retraction assembly includes a drive rod rotatably disposed in the adjustment hole and a clamping plate slidably disposed on the inner wall of the guide frame and fitted against the bottom of the drive rod.

[0010] As a preferred embodiment of the clamping mechanism described in this utility model, wherein:

[0011] One end of the clamp is fixed with an extended sliding protrusion, which fits against the inner wall of the guide frame.

[0012] Extended push rods are fixedly installed on both sides of the sliding protrusion, and reset rods are fixedly connected to both ends of the extended push rods.

[0013] As a preferred embodiment of the clamping mechanism described in this utility model, wherein:

[0014] A reset end is fixedly provided on the side wall of the guide frame, and an elastic element is connected to the reset end.

[0015] One end of the reset rod is fixedly connected to the elastic element.

[0016] As a preferred embodiment of the clamping mechanism described in this utility model, wherein:

[0017] The drive rod is threaded into the adjustment hole;

[0018] An operating component is fixedly connected to the top of the drive rod, and an extrusion component is fixedly connected to the bottom of the drive rod;

[0019] The top diameter of the extruded part is larger than the bottom diameter.

[0020] As a preferred embodiment of the clamping mechanism described in this utility model, wherein:

[0021] The sliding protrusion sidewall is fixedly provided with a mating groove;

[0022] The mating groove is fitted to the outer wall of the extrusion part.

[0023] The advantages of the clamping mechanism in this utility model are: it replaces bolt fixing, realizes "one-click" quick installation, adapts to cables of different diameters, and the return spring prevents the hand from directly contacting the conductive parts, thus improving safety.

[0024] Given that sensors are directly fixed in a specific position in the current environment, they cannot adapt to different cable angles or diameters, resulting in poor flexibility; when there is an angle difference between the cable position and the fixed position, conventional cable clamps cannot cope with complex angle differences, leading to cumbersome cable routing and difficult operation.

[0025] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0026] The control assembly includes a conductive patch mounted on one side of the clamp and a sensing unit connected to the other side of the clamp.

[0027] As a preferred embodiment of the circuit testing device described in this utility model, wherein:

[0028] A protruding rod is fixedly provided at the bottom of the guide frame, and an adjustment assembly is provided below the guide frame;

[0029] The top of the adjustment assembly is provided with a receiving cavity, which is rotatably engaged with the protruding rod.

[0030] As a preferred embodiment of the circuit testing device described in this utility model, wherein:

[0031] The adjustment assembly is fixedly connected to positioning holes at both ends;

[0032] A fixing bolt is provided through the surface of the adjustment assembly, and the bottom of the fixing bolt is elastically connected to the adjustment assembly.

[0033] As a preferred embodiment of the circuit testing device described in this utility model, wherein:

[0034] The bottom of the guide frame is provided with insertion holes, which are arranged in a ring array around the protruding rod;

[0035] The inner wall of the insertion hole slides in conjunction with the fixing bolt.

[0036] The beneficial effects of the line detection device in this utility model are: it supports 360° adjustment, adapts to complex wiring scenarios (such as corners and branch lines), ensures that the sensor and cable are in close contact throughout the entire process, and compared with single-point temperature measurement, the full contact design avoids missing local hot spots and improves monitoring accuracy (error ≤ ±1℃).

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0044] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0045] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0046] Example 1

[0047] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a clamping mechanism.

[0048] The conductor assembly 1 is used to control the pulling and routing of the cable under test, which is routed through the guide frame 11. The guide frame 11 is internally open, with rounded ends to facilitate the passage of the cable under test. An adjustment hole 12 is fixedly provided at the top of the guide frame 11. Through the adjustment hole 12, the take-up and release assembly 2 inside the guide frame 11 can be adjusted and controlled to ensure that the cable under test is clamped stably and securely.

[0049] The take-up and take-down assembly 2 acts directly on the cable under test. The drive rod 21 is rotatably mounted inside the adjustment hole 12 and can be threadedly connected to the adjustment hole 12. Therefore, when the drive rod 21 rotates along the corresponding thread, it can achieve its own lifting and lowering movement. The clamping plate 22 is slidably mounted on the inner wall of the guide frame 11 and can slide along the inner wall of the guide frame 11. The arc-shaped clamping side of the clamping plate 22 can cooperate with the inner wall of the guide frame 11 to form an effective clamping space for the cable under test.

[0050] One side of the clamping plate 22 is in contact with the bottom of the drive rod 21. When the drive rod 21 rotates and moves downward, the drive rod 21 can provide a pushing force to the clamping plate 22 while in contact with it, thereby ensuring that the arc-shaped clamping side of the clamping plate 22 can effectively function as the cable under test.

[0051] When it is not necessary to clamp the cable under test, simply rotate the drive rod 21 in the opposite direction to make the drive rod 21 rotate and move upward, thereby no longer providing clamping force to the cable under test.

[0052] This solution uses this type of clamping structure, which enables "one-click" quick installation, is compatible with cables of different diameters, is easy to operate, and does not require manual tightening of bolts one by one.

[0053] Example 2

[0054] Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0055] A sliding protrusion 221 is fixedly provided on the back of the arc-shaped clamping side of the clamping plate 22. The sliding protrusion 221 can fit tightly against the inner wall of the guide frame 11, ensuring that the clamping plate 22 can slide stably along the inner wall of the guide frame 11.

[0056] Extending push rods 222 are fixedly installed on both sides of the sliding protrusion 221. The extending push rods 222 are not on the same plane as the side wall of the guide frame 11, and protrude outward from the side wall of the guide frame 11. Reset rods 223 are fixedly connected to both ends of the extending push rods 222, and the reset rods 223 are aligned with the horizontal line of the guide frame 11.

[0057] A reset end 13 is fixedly provided on the side wall of the guide frame 11 to cooperate with the reset rod 223. An elastic element 131 is sleeved on the reset end 13. The elastic element 131 is fixedly connected to one end of the reset rod 223. The elastic element 131 can give the reset rod 223 a reset elastic force, ensuring that when the drive rod 21 rotates and moves upward, the elastic element 131 can push in the opposite direction, driving the sliding protrusion 221 and the clamping plate 22 to gradually return to the initial position.

[0058] The top of the drive rod 21 is fixedly connected to the operating component 211. By rotating the operating component 211, the drive rod 21 can be operated more effectively. The bottom of the drive rod 21 is fixedly connected to the pressing component 212, which is used to output pressure to the sliding protrusion 221. The side wall of the sliding protrusion 221 is fixedly provided with a mating groove 224 for better mating of the sliding protrusion 221.

[0059] The top diameter of the extruder 212 is larger than the bottom diameter, so the side wall of the extruder 212 is inclined. By setting the inclined surface, the extruder 212 can output a horizontal thrust to the mating groove 224 during the descent process.

[0060] Example 3

[0061] Reference Figures 1-4This is the third embodiment of the present invention, which adds a line detection device based on the above embodiments.

[0062] The control component 3 is used to control and adjust the angle and position of the entire line detection device and the cable under test, adapting to complex wiring scenarios. A conductive patch 31 is fixedly connected to one side of the clamping plate 22. The conductive patch 31 is located inside the arc-shaped clamping side of the clamping plate 22. A sensing unit 32 is fixedly connected to the back of the arc-shaped clamping side of the clamping plate 22. The sensing unit 32 is electrically connected to the conductive patch 31 and is used to directly sense and detect the temperature signal sent back by the conductive patch 31.

[0063] A protruding rod 33 is fixedly installed at the bottom of the guide frame 11. An adjustment assembly 34 is also connected below the guide frame 11. The adjustment assembly 34 is used to rotate with the protruding rod 33. A receiving cavity 341 is provided at the top of the adjustment assembly 34. The protruding rod 33 is inserted into the receiving cavity 341. The outer wall of the protruding rod 33 and the inner wall of the receiving cavity 341 can adopt a suitable concave-convex fit to realize the rotational adaptation of the protruding rod 33 and the receiving cavity 341.

[0064] The two ends of the adjustment assembly 34 are fixedly connected to the positioning holes 342, and can be fixed to the ground, wall or utility pole or other carrier by bolts. The surface of the adjustment assembly 34 is provided with a fixing bolt 343, and the bottom of the fixing bolt 343 is elastically connected to the adjustment assembly 34. In the default state, the fixing bolt 343 is subjected to elastic force and is in a squeezed state.

[0065] At the bottom of the guide frame 11, around the protruding rod 33, multiple insertion holes 35 are arranged in a circular array. The insertion holes 35 face the fixing bolt 343 and can slide with the fixing bolt 343. When it is necessary to adjust the angle of the entire line testing device to match the cable under test, simply pull the fixing bolt 343 manually to ensure that the fixing bolt 343 and the insertion hole 35 are separated. Then, under the rotational action of the protruding rod 33 and the adjustment assembly 34, rotate the guide frame 11 to adjust until it matches the installation angle of the cable under test.
