Description

Technical Field

[0001] This utility model relates to the field of electrical equipment testing technology, specifically to electrical equipment overheating fault detection equipment. Background Technology

[0002] The stable operation of electrical equipment is directly related to production safety and system reliability, and overheating is one of the main causes of electrical equipment failure. To promptly detect overheating problems caused by poor contact, insulation aging, abnormal load, etc., handheld infrared thermal imagers, with their advantages of non-contact temperature measurement and real-time imaging, have become a core tool for on-site fault detection.

[0003] Authorization announcement number CN 221743619 U discloses an electrical equipment overheating fault detection device, including an infrared thermal imager and a temporary support fixing mechanism, wherein the temporary support fixing mechanism is used to temporarily fix the infrared thermal imager. In use, this application can continuously detect thermal faults by fixing the infrared thermal imager to one side of the electrical equipment. However, in actual use, the device has the defect of inconvenience in installation and removal due to the fixing method of the screw, which causes the staff to spend extra time adjusting the device when switching detection points, and even abandon fixing due to the cumbersome operation, which directly affects the continuous detection effect of the thermal imager and makes it difficult to meet the needs of efficient and flexible on-site operation and maintenance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an electrical equipment overheating fault detection device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electrical equipment overheating fault detection device includes a placement ring, the inner wall of which forms an insertion channel for a thermal imager handle, and the bottom of which is provided with two parallel extensions.

[0007] A restraint sleeve has a pair of symmetrically arranged pivots on its outer wall. Each pivot is rotatably connected to a corresponding extension, and a torsion spring is elastically connected between the end of each pivot and the extension. Under the elastic force of the torsion spring, the restraint sleeve has a tendency to deflect its opening away from the opening of the placement ring. The restraint sleeve also includes:

[0008] Several elastic rings are equidistantly distributed along the axial direction of the binding sleeve, and the cross-section of the elastic rings is a wedge shape with the tip tilted downwards;

[0009] When the thermal imager handle is inserted into the restraint sleeve and the restraint sleeve is rotated to the point where its opening is concentric with the opening of the placement ring, the elastic ring is subjected to the squeezing action generated by the rotation of the restraint sleeve, and undergoes elastic deformation toward the thermal imager handle and presses the thermal imager handle. At the same time, the wedge-shaped tip of the elastic ring deforms and exerts a downward force on the thermal imager handle.

[0010] Preferably, the elastic ring has a guide slope on the side facing the insertion direction of the thermal imager handle, the guide slope is smoothly connected to the surface of the elastic ring, and the tilt angle is 40° to 50°.

[0011] Preferably, each of the elastic rings has a plurality of strip-shaped notches around its circumference to increase the deformation of the elastic ring.

[0012] Preferably, the inner wall of the placement ring is provided with a wear-resistant ring, which is made of rubber, and when the thermal imager handle is inserted into the restraint sleeve and deflects with it, the thermal imager handle abuts against the wear-resistant ring.

[0013] Preferably, the two extensions are provided with the same Y-shaped bracket, and the Y-shaped bracket is provided with a stop pad on the side facing the restraint sleeve. The stop pad is located on the rotation path of the restraint sleeve, and when the restraint sleeve rotates to abut the stop pad, the top end of the restraint sleeve has a force-bearing surface in the direction of insertion of the thermal imager handle.

[0014] Preferably, it also includes an adjusting member, the adjusting end of which is connected to the extension for adjusting the detection tilt angle of the thermal imager, and the adjusting member is provided with a screw for connecting to the support structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the combination of the restraint sleeve and the torsion spring enables convenient insertion and removal of the thermal imager, avoiding operational jamming. It can be quickly fixed without additional manual locking steps, effectively improving detection efficiency. At the same time, it takes into account the stability and adaptability of the fixation, preventing shaking during detection without increasing the difficulty of insertion and removal. It can also flexibly adjust the detection angle to adapt to different scenarios, reducing inconvenience in actual operation and enhancing the overall convenience and practicality of the device.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Example

[0025] like Figures 1-5 As shown, the electrical equipment overheating fault detection device includes a placement ring 1, the inner wall of which forms an insertion channel for the thermal imager handle, and the bottom of which is provided with two parallel extensions 10.

[0026] The inner wall of the placement ring 1 is provided with a wear-resistant ring 11, which is made of rubber. When the thermal imager handle is inserted into the restraint sleeve 2 and deflects with it, the thermal imager handle comes into contact with the wear-resistant ring 11. The elasticity and wear resistance of the rubber can reduce friction damage between the handle and the inner wall of the placement ring 1. At the same time, the flexible contact improves the stability of the handle when it is inserted and removed, avoiding equipment damage caused by hard collisions.

[0027] The restraint sleeve 2 has a pair of symmetrically arranged rotating shafts 20 on its outer wall. Each rotating shaft 20 is rotatably connected to a corresponding extension 10, and a torsion spring 201 is elastically connected between the end of the rotating shaft 20 and the extension 10. Under the elastic force of the torsion spring 201, the restraint sleeve 2 has a tendency to deflect its opening to maintain a misalignment with the opening of the placement ring 1. The restraint sleeve 2 also includes:

[0028] Several elastic rings 21 are equidistantly distributed along the axial direction of the binding sleeve 2, and the cross-section of the elastic rings 21 is a wedge shape with the tip tilted downward.

[0029] The elastic ring 21 has a guide slope on the side facing the insertion direction of the thermal imager handle. The guide slope is smoothly connected to the surface of the elastic ring 21, and the tilt angle is 40° to 50°. When the handle is inserted, the elastic ring 21 can be smoothly pushed to deform through the slope, reducing insertion resistance and improving the ease of insertion and removal.

[0030] Each elastic ring 21 has several strip-shaped notches 211 around its circumference to increase the deformation of the elastic ring 21, ensuring that it can adapt to handles of different diameters (within a certain range) and enhance the versatility of the device; at the same time, the deformed elastic ring 21 can tightly press the handle to achieve radial fixation.

[0031] When the thermal imager handle is inserted into the restraint sleeve 2 and the restraint sleeve 2 rotates to the point where its opening is concentric with the opening of the placement ring 1, the elastic ring 21 is subjected to the squeezing action generated by the rotation of the restraint sleeve 2 and undergoes elastic deformation toward the thermal imager handle, thus pressing the thermal imager handle tightly. At the same time, the wedge-shaped tip of the elastic ring 21 deforms and exerts a downward force on the thermal imager handle. The elastic deformation of the restraint sleeve 2 achieves rapid fixation of the thermal imager handle, and works in conjunction with the torsion spring 201 to achieve the linkage effect of "misalignment when not inserted and concentric fixation after insertion".

[0032] like Figure 5 As shown, the two extensions 10 are provided with the same Y-shaped bracket 101. The Y-shaped bracket 101 has a stop pad 102 on the side facing the restraint sleeve 2. The stop pad 102 is located on the rotation path of the restraint sleeve 2. When the restraint sleeve 2 rotates to abut the stop pad 102, the top of the restraint sleeve 2 has a force-bearing surface in the direction of insertion of the thermal imager handle. This makes it convenient for the user to push the restraint sleeve 2 to a fixed position by pressing the handle, simplifying the operation steps. This design lays the foundation for "easy insertion and removal". When the thermal imager handle is not inserted, the opening of the restraint sleeve 2 is misaligned, the elastic ring 21 does not undergo compression deformation, and the handle is inserted without resistance. After insertion, the spring force of the torsion spring 201 is overcome to make the opening concentric, realizing the automatic linkage of fixing and resetting without additional manual operation.

[0033] It also includes an adjustment component 3, the adjustment end of which is connected to the extension 10, for adjusting the detection tilt angle of the thermal imager to adapt to the overheating fault detection needs in different scenarios (such as equipment at high and low positions, pipes at different angles, etc.), thereby improving the versatility of the device; and the adjustment component 3 is provided with a screw 31 for connecting the support structure to adapt to the overheating fault detection needs in different scenarios (such as equipment at high and low positions, pipes at different angles, etc.), thereby improving the versatility of the device.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
