In order to ensure the normal operation of the equipment, it is crucial to regularly maintain the power equipment. In the maintenance process, the five-point safety belt, as a common safety belt suspension device, is widely used in the maintenance of substation power equipment. This safety belt meets the provisions of the new national standard GB6095-2009, and is mainly made of polyester or higher-strength woven tape, which is composed of a belt body, a safety rope, and metal fittings.

[0022] The safety belt suspension structure based on substation power equipment maintenance of the application, through the design of the clamping assembly, effectively enhances the resistance performance of the high-strength belt, effectively slows down the falling acceleration, and ensures the safety of the workers from being seriously injured. In the extreme unexpected situation, if the multiple buffering mechanisms and the clamping assembly fail to fully play the buffering role, the rapid extraction of the high-strength belt will trigger the sliding of the movable wedge, and then drive the support protrusion to move. The displacement of the support protrusion causes the displacement of the mounting member as a whole, and the chain reaction pushes the wedge to be activated, driving the moving plate to move in the horizontal direction. In this process, the ratchet on the moving plate will be embedded in the ratchet wheel and locked, forcing the winding drum to stop rotating, thereby terminating the further expansion of the high-strength belt, achieving instant braking in the sudden falling situation, and effectively avoiding various safety hazards caused by sudden falling.

[0035] In order to make the objects, technical solutions and advantages of the present application clearer, further detailed description will be given below with reference to the drawings and examples. However, it should be understood that the specific examples described herein are only used to explain the present application and do not limit the scope of the present application.

[0036] It should be noted that when an element is referred to as "provided on" or "provided with" another element, it can be directly on the other element or there can be a middle element, and when an element is referred to as "connected to" or "connected with" another element, it can be directly connected to the other element or there can be a middle element, and "fixedly connected" means fixed connection, and there are many ways of fixed connection, which are not limited by the present application, and the terms "vertical", "horizontal", "left", "right" and similar terms used herein are only for the purpose of illustration and are not the only implementation.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs, and the terms used herein in the specification only for the purpose of describing specific embodiments and are not intended to limit the present application, and the term "and / or" used herein includes any and all combinations of one or more related listed items;

[0038] Please refer to the drawings attached to the specification Figures 1-10The present application provides a first embodiment of a safety belt suspension structure based on substation power equipment maintenance, in which the safety belt suspension structure is combined with a high-strength belt 4 and a fixing member 3 to form a stable suspension system. In the suspension system, one end of the high-strength belt 4 is fixed to the connecting portion 2 of the safety clothing 1, and the other end is connected to the fixing member 3 which is pre-fixed to the power equipment. This effectively avoids the additional burden on the workers, because the weight of the high-strength belt 4 is acceptable compared to the five-point safety belt, and through this connection method, it effectively prevents falling accidents caused by equipment failure or operation errors, providing a reliable safety guarantee for workers.

[0039] The above suspension system mainly includes the safety clothing 1 and the fixing member 3. The safety clothing 1 is a five-point safety belt in the prior art. Specifically, the safety clothing 1 has a waist belt 11, shoulder belts 12, leg belts 13, and safety hooks 14. The waist belt 11 is wrapped around the worker's waist and tied from the front. The waist belt 11 has a connecting portion 2 at the center of the front. The shoulder belts 12 are two in number and are connected to the connecting portion 2. The shoulder belts 12 cross over the worker's front and extend downward across the worker's two shoulders and are fixed to the back of the waist belt 11. The X-shaped structure is arranged in front of the worker, and is fixed by the cross structure to better protect the worker. The leg belts 13 are two in number and are connected to the connecting portion 2. The leg belts 13 cross over the worker's front and extend to the back of the waist belt 11. One side of the waist belt 11 is connected with the safety hooks 14.

[0040] Of course, the position of the safety hooks 14 can also be installed on the shoulder belts 12 or other positions.

[0041] Further, as a possible solution to the above scheme, an alarm device that outputs an audible signal or a vibration signal is designed on the waist belt 11. The alarm device can include a communication unit and transmit whether a sudden drop occurs

[0042] Further, as a possible solution to the above scheme, an altimeter that measures the height of the worker is designed on the waist belt 11. If the altimeter measures a rapid change, it is determined that a sudden drop has occurred.

[0043] The fixing member 3 is pre-fixed to the power equipment to be detected. The fixing member 3 is provided with a high-strength belt 4, and one end of the high-strength belt 4 is fixed to the connecting portion 2.

[0044] The protection principle of the suspension system of the present embodiment mainly relies on the comprehensive support of the five-point safety belt, the stable connection of the fixing member 3 and the strong tension of the high-strength belt 4. These three factors together form a stable and reliable suspension system, which provides comprehensive safety protection for workers during the maintenance of power equipment in the substation. Among them, the high-strength belt 4 provides additional protection for workers in addition to the safety hook 14, greatly reducing the risk of falling due to equipment failure or operation errors.

[0045] Please refer to the attached drawings of the specification Figures 1-10 The present application provides a second embodiment of the safety belt suspension structure based on the maintenance of power equipment in the substation. Based on the structure of the first embodiment, it focuses on the multiple buffering mechanisms in the safety belt suspension structure, including the high-strength belt 4 in the shape of a cross, the design with folding part 45 and fixing ring 46, and the combination of spring and reel 33. When the worker falls, these designs can absorb the impact force layer by layer, significantly reducing the damage caused by sudden falling. Specifically, the high-strength belt 4 in the shape of a cross can orderly break and release when subjected to excessive tension through the design of the clamp 41 and the breaking point, thereby reducing the impact force. The folding part 45 and the fixing ring 46 release the folding part 45 when necessary to further absorb the impact force through the design of the second breaking point 461. The combination of spring and reel 33 makes the high-strength belt 4 receive a certain resistance when stretched, which helps to control the descent speed and provide buffering. Specifically, the high-strength belt 4 is improved as follows:

[0046] The two sides of the high-strength belt 4 are bent and connected by the clamp 41, so that the high-strength belt 4 forms a first connecting segment 42 at the top, a second connecting segment 43 at the bottom, and at least one third connecting segment 44 at the side. The first connecting segment 42, the second connecting segment 43 and the third connecting segment 44 form a cross shape. The transverse part of the clamp 41 has a first breaking point 411 that is easy to break, so that the third connecting segment 44 is released after the first breaking point 411 breaks. The first connecting segment 42 and / or the second connecting segment 43 have multiple folding parts 45 arranged in a folding manner. The folding part 45 has a fixing ring 46, and the fixing ring 46 has a second breaking point 461, so that the folding part 45 is released after the second breaking point 461 breaks.

[0047] The fixing member 3 includes a frame 31 mounted on the power equipment to be detected. The frame 31 is provided with a rotating shaft 32, and the rotating shaft 32 is provided with a reel 33. The reel 33 is arranged in the extension direction and provided with a first spring 34. The high-strength belt 4 is connected to the first spring 34 and partially wound around the reel 33. When the high-strength belt 4 is stretched, the first spring 34 provides a force to contract the high-strength belt 4.

[0048] The protection principle of the suspension system of the present embodiment is shown as follows:

[0049] Layered impact absorption: when the worker falls, first, the high-strength belt 4 in the shape of a cross will bear the main impact force. As the impact force increases, the first breaking point 411 will break, releasing the third connecting section 44, thereby dispersing the impact force and reducing its peak value.

[0050] Release of the folding part 45: if the impact force is still too large, the second breaking point 461 will break, releasing the folding part 45. The multi-layer structure of the folding part 45 can further absorb the impact force, while increasing the time of descent and reducing the acceleration, thereby reducing the harm to the worker.

[0051] Spring and reel 33 buffer: throughout the falling process, the combination of the spring and the reel 33 will continue to provide resistance, control the speed of descent, so that the worker can land more smoothly, avoiding the harm caused by sudden falling.

[0052] Please refer to the attached drawings Figures 1-10 The present application provides a third embodiment of the safety belt suspension structure based on the maintenance of power equipment in a transformer substation. In this embodiment, on the basis of the structure of the second embodiment, the emergency braking system in the safety belt suspension structure is described, mainly through the design of the clamping assembly 5, the push wedge 63, the ratchet 35 and the ratchet teeth 361, etc. In extreme cases, if the multiple buffering mechanisms and the clamping assembly 5 cannot provide sufficient buffering, the rapid pulling out of the high-strength belt 4 will trigger a series of chain reactions: the movable wedge 54 slides out and drives the support protrusion 65 to move, thereby driving the mounting member 6 to move as a whole. During the above process, the push wedge 63 is activated and drives the sliding plate to move horizontally, so that the ratchet teeth 361 on the sliding plate are embedded in the ratchet 35 and lock the ratchet 35, thereby forcing the reel 33 to stop rotating and terminating the further extension of the high-strength belt 4. This emergency braking system can achieve instantaneous braking in the case of sudden falling, effectively avoiding various safety hazards caused by sudden falling. Specifically, the fixing member 3 is improved as follows:

[0053] The reel 33 is provided with a ratchet 35 at both ends, and the fixing member 3 is provided with a sliding plate 36 connected slidingly, and the sliding plate 36 is provided with ratchet teeth 361 in cooperation with the ratchet 35, and the ratchet 35 is located on the sliding path of the sliding plate 36.

[0054] Further, the fixing member 3 is further provided with a clamping assembly 5, the clamping assembly 5 comprises a fixed block 51 installed on the fixing member 3, the fixed block 51 has a first surface 511 parallel to the high-strength belt 4 in friction fit, the two sides of the fixed block 51 extend upward and form two support plates 52, a fixed wedge block 53 is fixed between the two support plates 52, the fixed wedge block 53 has a first inclined surface 531 inclined downward toward the high-strength belt 4, a movable wedge block 54 is arranged between the first inclined surface 531, the support plate 52 and the top surface of the high-strength belt 4, the movable wedge block 54 has a second surface 541 parallel to the high-strength belt 4 and a second inclined surface 542 parallel to the first inclined surface 531, and as the movable wedge block 54 moves downward, the distance between the first surface 511 and the second surface 541 gradually decreases.

[0055] Further, the fixing member 3 is further provided with a mounting member 6, the mounting member 6 is provided with a strip-shaped sliding groove 61, a rivet 62 passes through the strip-shaped sliding groove 61 and is fixed on the fixing member 3, one end of the strip-shaped sliding groove 61 is spaced apart from the rivet 62, a pushing wedge block 63 is installed on the mounting member 6, the side surface of the pushing wedge block 63 has a third inclined surface 631, the sliding plate 36 has a horizontal surface 362 in contact with the third inclined surface 631, the fixing member 3 is further connected with a connecting frame 64, one end of the connecting frame 64 has a support protrusion 65 supporting the movable wedge block 54.

[0056] Further, the fixing member 3 is further provided with a pulling spring 7 and the other end of the pulling spring 7 is fixed on the mounting member 6.

[0057] Further, the high-strength belt 4 is further provided with a connecting member 8, the connecting member 8 is detachably connected with the connecting part 2, for example, threaded connection, a stud is arranged on the connecting member 8, a threaded hole with a matching structure of the stud is arranged on the connecting part 2, and the installation of the connecting member 8 and the connecting part 2 is realized through threaded fit.

[0058] It should be noted that the connecting member 8 and the connecting member 2 are designed as an integral structure and cannot be disassembled, but the high-strength belt 8 and the connecting part 2 are detachably installed and are installed by using a buckle structure similar to the safety clothes 1.

[0059] Further, the connecting member 8 is further connected with a connecting belt 9, one end of the connecting belt 9 is buckled with the waist belt 11 or the shoulder belt 12.

[0060] The protection and fixing effect of the high-strength belt 4 (and the connected safety device) is achieved through the locking mechanism of the ratchet 35 and the ratchet teeth 361, the friction and wedge effect of the clamping assembly 5, the linkage mechanism of the pushing wedge 63 and the sliding plate 36, the resetting action of the tension spring 7, and the detachable connection of the connecting piece 8 and the connecting belt 9, etc. It ensures that the worker can be effectively protected when facing potential danger.

[0061] The protection principle of the safety belt suspension structure based on the maintenance of power equipment in a transformer substation provided by the above embodiment is as follows:

[0062] The altimeter on the waist belt 11 monitors the height change of the worker in real time. If the measured height changes rapidly, it is determined that the sudden drop phenomenon occurs, and the alarm device will also start accordingly, reminding the worker to pay attention and take measures. Once a fall or other emergency occurs, the high-strength belt 4 will play a key role in bearing the impact force generated by the fall to prevent the worker from being injured. At this time, the worker can quickly adjust the position or seek help through the safety hook 14 and other connection points on the safety belt.

[0063] Further, in the case of a large sudden drop impact force, the cross-shaped high-strength belt 4 will bear the main impact force. As the impact force increases, the first breaking point 411 will break, releasing the third connecting segment 44, thereby dispersing the impact force and reducing its peak value. If the impact force is still too large, the second breaking point 461 will break, releasing the folding part 45. The multi-layer structure of the folding part 45 can further absorb the impact force, while increasing the time of descent and reducing the acceleration, thereby reducing the harm to the worker. At the same time, the combination of the spring and the winding drum 33 will continue to provide resistance throughout the falling process, controlling the descent speed, so that the worker can land more smoothly, avoiding the harm caused by the sudden drop.

[0064] Further, after the multiple buffering mechanisms cannot effectively buffer, the rapid movement of the high-strength belt 4 will drive the movable wedge 54 to move downward, causing the distance between the first surface 511 and the second surface 541 to gradually decrease, thereby increasing the friction with the high-strength belt 4. At the same time, the movable wedge 54 will produce a wedging effect under the action of the second inclined surface 542 and the first inclined surface 531, further increasing the clamping force. At the same time, the ejected movable wedge 54 part drives the support protrusion 65 to move, and then drives the mounting member 6 to move. When the mounting member 6 moves, since the third inclined surface 631 of the push wedge 63 is in contact with the horizontal surface 362 of the sliding plate 36, this movement will cause the push wedge 63 to produce a certain displacement, thereby driving the moving plate to move horizontally, and the ratchet 35 and the ratchet teeth 361 are combined and interacted to prevent the rotation of the winding drum 33, thereby realizing the emergency stop action for the high-strength belt 4. This locking mechanism can prevent rapid and uncontrolled descent caused by accidental situations (such as falling of workers), thereby providing a certain safety buffer.

[0065] In summary, based on the safety belt suspension structure of the power equipment maintenance of the transformer substation, through the cooperative action of real-time monitoring of height change, multiple buffering mechanisms and emergency braking system, the harm caused by falling and other emergency situations during the maintenance process of the workers is effectively prevented, and comprehensive and reliable safety protection is provided.

[0066] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
