Description

Technical Field

[0001] This utility model relates to the field of explosion-proof cable technology, and more specifically, to an explosion-proof cable for power engineering equipped with a testing mechanism. Background Technology

[0002] Explosion-proof cables for power engineering are specially designed cables with flame-retardant, high-temperature resistant, and impact-resistant properties. They can be used safely in flammable and explosive environments. Their outer layer is usually wrapped with high-strength materials, which can effectively prevent explosions caused by internal sparks or high temperatures. They also have excellent insulation and anti-interference performance and are widely used in power transmission and equipment connection in high-risk places such as petroleum, chemical, and mining industries to ensure the safe and stable operation of projects.

[0003] According to a search, Chinese patent document, publication number CN219202832U, discloses an explosion-proof cable for power engineering with a testing mechanism, relating to the field of power engineering. This explosion-proof cable for power engineering with a testing mechanism includes a cable body, an insulating ring plate, a first splicing plate, and a second splicing plate arranged on the outside of the cable body. A testing device is arranged on the inner surface of the insulating ring plate, and a splicing mechanism is arranged on the outside of the cable body. This explosion-proof cable for power engineering with a testing mechanism uses an insulating ring plate on the surface of the cable body. Multiple fixed cylinders, sliding rods, and balls are arranged in a ring around the center of the insulating ring plate. The balls intersect with the surface of the cable body. Manually pushing the insulating ring plate moves it across the surface of the cable body, causing the balls to slide. If cracks or damage appear on the surface of the cable body, the balls will sink into the cracks, making it difficult to move the insulating ring plate. This allows for the detection of damage to the cable body surface, solving the problem of omissions that are easily caused by manual visual inspection. However, when using this utility model, its insulating ring plate lacks an automatic reset function, requiring workers to manually reset it. This is a cumbersome process when working at heights, which can easily increase the risk of accidents.

[0004] In conclusion, to improve the safety and ease of operation of high-altitude operations, it is necessary to solve the problem of the insulating ring plate's inability to automatically reset, enabling it to quickly and automatically return to its original position after operation, thereby reducing manual intervention, lowering operational risks, and improving work efficiency. Utility Model Content

[0005] The present invention provides an explosion-proof cable for power engineering with a testing mechanism, which aims to solve the problem that, compared with a patented explosion-proof cable for power engineering with a testing mechanism, the insulating ring plate lacks an automatic reset function, which easily increases the operational risk.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof cable for power engineering with a detection mechanism, comprising a cable body, a first fixing plate at the right end of the cable body, a second fixing plate at the left end of the cable body, multiple sets of supports installed on the right side of the second fixing plate, the multiple sets of supports being arranged in a circumferential array, a reset shaft rotatably connected between each set of supports, a detection ring slidably connected to the outside of the cable body, a lifting ring fixed on the left side of the detection ring corresponding to the position of each set of supports, a connecting rope connected between the lifting ring and the corresponding reset shaft, the connecting rope being wound around the outside of the reset shaft, a docking mechanism provided on the two fixing plates, and a traction mechanism provided on the detection ring.

[0007] In a preferred embodiment, the docking mechanism includes a fixing component and a plugging component, wherein the fixing component is used to assist in positioning the two fixing disks, and the plugging component is used to fix the two fixing disks.

[0008] In a preferred embodiment, the fixing component includes a plurality of first positioning holes formed on the first fixing plate, the plurality of first positioning holes being distributed in a circumferential array, and second positioning holes being formed on the second fixing plate at positions corresponding to the first positioning holes.

[0009] In a preferred embodiment, the plug-in assembly includes two plug blocks fixed on a first fixing plate. The outer sides of the two plug blocks are provided with slots, and spring pieces are provided inside the slots. A locking block is fixed on the spring piece. Two sleeves are fixed on the second fixing plate, and the outer sides of the sleeves are provided with locking grooves.

[0010] In a preferred embodiment, the traction mechanism includes an installation component and a pulling component, wherein the installation component is used to install the pulling component, and the pulling component is used for workers to pull the detection ring.

[0011] In a preferred embodiment, the mounting assembly includes two mounting slots formed on the detection ring, each mounting slot having a connecting shaft rotatably connected inside, a sleeve fixed to the outside of the connecting shaft, and a connecting rod fixed to the outside of the sleeve.

[0012] In a preferred embodiment, the traction assembly includes a finger ring fixed to the end of the link, the outside of which is covered with a silicone pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention achieves automatic reset of the detection ring by setting a connecting rope on the surface of the detection ring and winding the other end of the rope around the reset shaft. This significantly simplifies the operation process of high-altitude cable inspection, eliminating the need for operators to frequently adjust the position of the detection ring, saving time and reducing labor intensity. At the same time, the automatic reset mechanism reduces the number of movements during high-altitude operations, effectively avoiding safety hazards caused by repeated operations. This advantage is particularly prominent in large-span scenarios, making high-altitude cable inspection operations more efficient and safer, and providing reliable technical support for power inspection.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 6An explosion-proof cable for power engineering with a detection mechanism includes a cable body 1, a first fixing plate 2 at the right end of the cable body 1, a second fixing plate 3 at the left end of the cable body 1, multiple sets of supports 4 installed on the right side of the second fixing plate 3, the multiple sets of supports 4 are arranged in a circumferential array, and a reset shaft 5 is rotatably connected between each set of supports 4. A detection ring 6 is slidably connected to the outside of the cable body 1, and a lifting ring 7 is fixed on the left side of the detection ring 6 corresponding to the position of each set of supports 4. A connecting rope 8 is connected between the lifting ring 7 and the corresponding reset shaft 5, and the connecting rope 8 is wound around the outside of the reset shaft 5. A docking mechanism is provided on the two fixing plates, and a traction mechanism is provided on the detection ring 6.

[0024] It should be noted that the detection ring 6 adopts the same structure as the detection device in the comparative patent. It detects the surface fracture of the cable by moving the ball. Therefore, the working principle of the detection ring 6 will not be explained. When the detection ring 6 moves, the connecting rope 8 is pulled by the lifting ring 7. The connecting rope 8 drives the reset shaft 5 to rotate. When the staff releases the detection ring 6, the reset shaft 5 automatically rotates back and winds the connecting rope 8, thereby driving the detection ring 6 to reset.

[0025] Refer to the instruction manual appendix Figure 1 The docking mechanism includes a fixing component and a plug-in component. The fixing component is used to assist in positioning the two fixing plates, and the plug-in component is used to fix the two fixing plates.

[0026] It should be noted that the first fixing plate 2 and the second fixing plate 3 are set in multiple places on the entire cable body 1 for segmented setting of detection rings 6.

[0027] Refer to the instruction manual appendix Figure 2 and Figure 4 The fixing component includes a plurality of first positioning holes 101 formed on the first fixing plate 2, the plurality of first positioning holes 101 being arranged in a circular array, and a second positioning hole 102 being formed on the second fixing plate 3 at a position corresponding to the first positioning holes 101.

[0028] It should be noted that the first fixed plate 2 and the second fixed plate 3 can be fixed together by bolts, the first positioning hole 101 and the second positioning hole 102.

[0029] Refer to the instruction manual appendix Figure 2 and Figure 4 The plug-in assembly includes two plug blocks 103 fixed on the first fixed plate 2. The outer sides of the two plug blocks 103 are provided with slots 104. The slots 104 are provided with spring pieces 105. The spring pieces 105 are fixed with locking blocks 106. The second fixed plate 3 is fixed with two sleeves 107. The outer sides of the sleeves 107 are provided with locking grooves 108.

[0030] It should be noted that when the insert block 103 is inserted into the sleeve 107, the locking block 106 is squeezed, causing the spring piece 105 to bend. When the locking block 106 moves to the position of the slot 108, the spring piece 105 releases its elastic potential energy, thereby causing the locking block 106 to be locked into the slot 108.

[0031] Refer to the instruction manual appendix Figure 2 The traction mechanism includes an installation component and a pulling component. The installation component is used to install the pulling component, and the pulling component is used for workers to pull the inspection ring 6.

[0032] It should be noted that staff can pull the traction component with their fingers. The traction component is symmetrically arranged on the detection ring 6, which can improve the uniformity of the pulling force when pulling.

[0033] Refer to the instruction manual appendix Figure 2 and Figure 3 The mounting assembly includes two mounting slots 91 formed on the detection ring 6. A connecting shaft 92 is rotatably connected inside each of the two mounting slots 91. A sleeve 93 is fixed to the outside of the connecting shaft 92, and a connecting rod 94 is fixed to the outside of the sleeve 93.

[0034] It should be noted that the connecting rod 94 and the sleeve 93 can rotate with the cooperation of the connecting shaft 92 and be housed inside the mounting slot 91.

[0035] Refer to the instruction manual appendix Figure 2 and Figure 3 The traction assembly includes a ring 95 fixed to the end of the connecting rod 94, and the outside of the ring 95 is covered with a silicone pad.

[0036] It should be noted that staff can hook their fingers around ring 95 to pull on detection ring 6.

[0037] Working principle: During testing, the operator hooks the finger ring 95 on the testing ring 6. The finger ring 95 is wrapped with a silicone pad and is installed in the mounting groove 91 of the testing ring 6 via the connecting rod 94, the sleeve 93, and the connecting shaft 92, allowing rotation and retraction. Pulling the testing ring 6 causes the connecting rope 8 to be pulled by the lifting ring 7. The connecting rope 8 drives the reset shaft 5 to rotate. When the operator releases the finger ring 95, the reset shaft 5 automatically rotates back and winds the connecting rope 8, pulling the testing ring 6 back to its initial position. The first fixed plate 2 and the second fixed plate 3 are fixed together by bolts through the first positioning hole 101 and the second positioning hole 102. At the same time, the insert block 103 on the first fixed plate 2 is inserted into the sleeve 107 on the second fixed plate 3. The spring piece 105 in the slot 104 of the insert block 103 drives the locking block 106 to engage with the locking groove 108 on the outside of the sleeve 107, achieving a firm connection between the two fixed plates.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
