[0002] Substation power equipment is indispensable in power transportation, and its operating status is directly related to the quality of power supply. In order to ensure the normal operation of the equipment, it is very important to carry out regular maintenance of power equipment. During 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 type of safety belt complies with the provisions of the new national standard GB6095-2009. It is mainly made of polyester or higher strength webbing, and consists of a belt body, safety rope and metal accessories. Its main function is to prevent workers from falling at high altitudes, and to ensure the safety of workers through the combined action of safety ropes and metal accessories.

[0003] In order to prevent workers from being injured due to rapid descent during a fall, the prior art has adopted a solution of adding a buffer bag, as shown in patent CN207734488U, which includes a foldable safety rope to provide a certain buffer protection for the falling workers.

[0019] The safety belt suspension structure based on substation power equipment maintenance of the present invention has the following beneficial effects:

[0020] 1. In the safety belt suspension structure for maintenance of power equipment in a substation of the present invention, the high-strength belt does not add extra weight to the five-point safety belt, which puts less burden on the staff. At the same time, through the combination of the high-strength belt and the fixing parts, a relatively stable suspension system is formed, which effectively prevents falling accidents caused by equipment failure or operating errors.

[0021] 2. The safety belt suspension structure for substation power equipment maintenance of the present invention adopts multiple buffer mechanisms. The cross-shaped high-strength belt, folding part and fixed ring, spring and rotating drum together constitute multiple buffer mechanisms. The above mechanism can absorb the impact force layer by layer when the worker falls, significantly reducing the damage caused by sudden fall;

[0022] 3. The safety belt suspension structure based on the maintenance of power equipment in substations of the present invention effectively enhances the resistance efficiency of the high-strength belt by designing the clamping assembly, effectively slows down the acceleration of falling, and ensures the safety of the workers from being seriously injured. In extreme accidental situations, if the multiple buffering mechanisms and the clamping assembly fail to fully play the buffering role, the rapid withdrawal of the high-strength belt will trigger the sliding of the movable wedge block, thereby driving the support protrusion to move accordingly. The displacement of this support protrusion causes the entire mounting part to displace, and the chain reaction pushes the wedge block to be activated, driving the movable plate to move in the horizontal direction. In this process, the ratchet on the movable plate will be embedded in the ratchet wheel and locked, forcing the reel to stop rotating, thereby terminating the further extension of the high-strength belt, achieving instant braking in the event of a sudden fall, and effectively avoiding various safety hazards caused by a sudden fall.

[0023] With reference to the following description and drawings, a specific embodiment of the present invention is disclosed in detail, indicating the manner in which the principle of the present invention can be adopted. It should be understood that the scope of the embodiment of the present invention is not limited thereby, and the embodiment of the present invention includes many changes, modifications and equivalents.

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

[0038] Please refer to the instruction manual Figure 1-10The present invention provides a first embodiment of a safety belt suspension structure based on the maintenance of power equipment in a substation. In this embodiment, the safety belt suspension structure mainly forms a stable suspension system through the combination of a high-strength belt 4 and a fixing member 3. In this 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 pre-fixed on the power equipment. It effectively avoids adding extra burden to the staff, 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 that may be caused by equipment failure or operational errors, providing a reliable safety guarantee for the staff.

[0039] The above-mentioned suspension system mainly includes a safety garment 1 and a fixing part 3. The safety garment 1 is a five-point safety belt in the prior art. Specifically, the safety garment 1 has a waist belt 11, a shoulder belt 12, a leg belt 13 and a safety hook 14. The waist belt 11 is wrapped around the waist of the worker and fastened from the front. A connecting part 2 is provided at the front center of the waist belt 11. The number of the shoulder belts 12 is two and the two shoulder belts 12 are connected to the above-mentioned connecting part 2. The shoulder belts 12 cross from the front of the worker and extend downward across the two shoulders of the worker and are fixed to the rear of the waist belt 11. Specifically, the X-shaped structure is arranged in front of the worker and is fixed by the cross structure to better realize the protection of the worker. The number of the leg belts 13 is two and the two leg belts 13 are connected to the above-mentioned connecting part 2. The leg belts 13 respectively cross the two legs of the worker from the front and extend and are fixed to the rear of the waist belt 11. A safety hook 14 is connected to one side of the waist belt 11.

[0040] Of course, the safety hook 14 may also be installed on the shoulder strap 12 or at other locations.

[0041] Furthermore, as a possible solution of the above solution, an alarm device for outputting a sound signal or a vibration signal is also designed on the above waist belt 11. The alarm device may include a communication unit and transmit whether a sudden fall occurs.

[0042] Furthermore, as a possible solution of the above solution, an altimeter for measuring the height of the worker is also designed on the above belt 11. If the altimeter changes rapidly, it is determined that a sudden fall has occurred.

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

[0044] The protection principle of the suspension system of this embodiment mainly relies on the comprehensive support of the five-point safety belt, the stable connection of the fixing member 3 and the strong pulling force of the high-strength belt 4. These three together constitute 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 workers with additional protection in addition to the safety hook 14, greatly reducing the risk of falling due to equipment failure or operating errors.

[0045] Please refer to the instruction manual Figure 1-10 The present invention provides a second embodiment of a safety belt suspension structure based on the maintenance of power equipment in a substation. On the basis of the structure of the first embodiment, the multiple buffering mechanisms in the safety belt suspension structure are highlighted, and the multiple buffering mechanisms include a high-strength belt 4 in a cross shape, a design with a folding portion 45 and a fixing ring 46, and a combination of a spring and a rotating drum. When a worker falls, these designs can absorb the impact force layer by layer, significantly reducing the damage caused by a sudden fall. Specifically, the high-strength belt 4 in a cross shape can be broken and released in an orderly manner when subjected to excessive tension through the design of a clip 41 and a fracture, thereby reducing the impact force. The folding portion 45 and the fixing ring 46 are designed with a second fracture 461, and the folding portion 45 is released when necessary to further absorb the impact force. The combination of the spring and the rotating drum causes the high-strength belt 4 to be subjected to a certain resistance when stretched, which helps to control the descent speed and provide buffering. Specifically, the above-mentioned high-strength belt 4 has been improved as follows:

[0046] The two sides of the high-strength belt 4 are bent and connected by a clip 41, so that the high-strength belt 4 forms a first connecting section 42 located at the top, a second connecting section 43 located at the bottom and at least one third connecting section 44 located at the side, the first connecting section 42, the second connecting section 43 and the third connecting section 44 form a cross-like shape, the transverse part of the clip 41 has a first fracture 411 that is easy to be damaged, so that the third connecting section 44 is released after the first fracture 411 is broken, the first connecting section 42 and / or the second connecting section 43 has a folded multi-layer folding portion 45, the folding portion 45 has a fixing ring 46, and the fixing ring 46 has a second fracture 461, so that the folding portion 45 is released after the second fracture 461 is broken.

[0047] The fixing member 3 includes a frame 31 installed on the electrical equipment to be tested, a rotating shaft 32 is installed on the frame 31, a reel 33 is passed through the rotating shaft 32, a first spring 34 is arranged on the rotating drum in the extension direction, the high-strength belt 4 is connected to the first spring 34 and partially wound on the rotating drum, and 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 this embodiment is as follows:

[0049] Absorbing impact force layer by layer: When a worker falls, first, the cross-shaped high-strength belt 4 will bear the main impact force. As the impact force increases, the first fracture opening 411 will break, releasing the third connecting section 44, thereby dispersing the impact force and reducing its peak value.

[0050] Release of the folded portion 45: If the impact force is still too great, the second fracture opening 461 will break, releasing the folded portion 45. The multi-layer structure of the folded portion 45 can further absorb the impact force, while increasing the descending time and reducing the acceleration, thereby reducing the harm to the staff.

[0051] Spring and drum cushioning: During the entire falling process, the combination of springs and drums will continue to provide resistance and control the descent speed, allowing workers to land more smoothly and avoid injuries caused by sudden falls.

[0052] Please refer to the instruction manual Figure 1-10 The present invention provides a third embodiment of a safety belt suspension structure based on the maintenance of power equipment in a substation. In this embodiment, on the basis of the structure of the second embodiment, an emergency braking system in the safety belt suspension structure is described, which is mainly implemented by designs such as a clamping assembly 5, a pushing wedge 63, a ratchet 35 and a ratchet 361. 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. In the above process, the pushing wedge 63 is activated and drives the movable plate to move horizontally, so that the ratchet 361 on the movable plate is embedded in the ratchet 35 and locks 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 instant braking in the event of a sudden fall, effectively avoiding various safety hazards caused by a sudden fall. Specifically, the above-mentioned fixing member 3 has been improved as follows:

[0053] Ratchets 35 are provided at both ends of the rotating drum, a sliding plate 36 slidably connected is installed on the fixing member 3 , a ratchet 361 which is a matching structure with the ratchet 35 is installed on the sliding plate 36 , and the ratchet 35 is located on the sliding path of the sliding plate 36 .

[0054] Furthermore, a clamping assembly 5 is also provided on the fixing member 3, and the clamping assembly 5 includes a fixing block 51 installed on the fixing member 3, the fixing block 51 has a first surface 511 that is frictionally matched with and parallel to the high-strength belt 4, and the two sides of the fixing block 51 extend upward to form two support plates 52, and a fixed wedge 53 is fixed between the two support plates 52, and the fixed wedge 53 has a first inclined surface 531 facing one side of the high-strength belt 4 and inclined downward, and a movable wedge 54 is provided between the first inclined surface 531, the support plate 52 and the top surface of the high-strength belt 4, and the movable wedge 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 54 moves downward, the distance between the first surface 511 and the second surface 541 gradually decreases.

[0055] Furthermore, a mounting member 6 is also provided on the fixing member 3, and a strip groove 61 is opened on the mounting member 6, and a rivet 62 passes through the strip groove 61 and is fixed on the fixing member 3, and one end of the strip groove 61 is at a certain distance from the rivet 62, and a pushing wedge 63 is installed on the mounting member 6, and the side surface of the pushing wedge 63 has a third inclined surface 631, and the sliding plate 36 has a horizontal surface 362 in contact with the third inclined surface 631, and a connecting frame 64 is also connected and fixed to the fixing member 3, and one end of the connecting frame 64 has a supporting protrusion 65 for supporting the movable wedge 54.

[0056] Furthermore, a tension spring 7 is installed on the fixing member 3 and the other end of the tension spring 7 is fixed on the mounting member 6 .

[0057] Furthermore, a connecting piece 8 is also provided on the high-strength belt 4, and the connecting piece 8 and the connecting part 2 are detachably connected, for example, a threaded connection, a stud is provided on the connecting piece 8, and a threaded hole that is a matching structure with the stud is provided on the connecting part 2, and the installation of the connecting piece 8 and the connecting part 2 is achieved through threaded matching.

[0058] It should be noted that generally the connector 8 and the connector 2 are designed as an integrated structure and cannot be disassembled, but the high-strength belt 8 and the connecting part 2 are detachably installed and are installed using a snap-on structure similar to the safety clothing 1.

[0059] Furthermore, a connecting belt 9 is connected to the connecting member 8 , and one end of the connecting belt 9 is buckled and connected to the waist belt 11 or the shoulder belt 12 .

[0060] This embodiment mainly realizes the protection and fixation of the high-strength belt 4 (and the safety device connected to it) through various means such as the locking mechanism of the ratchet 35 and the ratchet teeth 361, the friction and wedging effect of the clamping assembly 5, the linkage mechanism of the push wedge block 63 and the sliding plate 36, the reset effect of the tension spring 7, and the detachable connection between the connecting piece 8 and the connecting belt 9, thereby ensuring that the staff can be effectively protected when facing potential dangers.

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

[0062] The altimeter on the belt 11 monitors the height changes of the workers in real time. If the measured height changes rapidly, it is determined that a sudden fall has occurred, and the alarm device will be activated accordingly to remind the workers to pay attention and take countermeasures. Once a fall or other emergency occurs, the high-strength belt 4 will play a key role in withstanding the impact force caused by the fall and preventing the workers from being injured. At this time, the workers can quickly adjust their position or seek rescue through the safety hook 14 and other connection points on the safety belt.

[0063] Furthermore, if the impact force of the sudden fall is large, the cross-shaped high-strength belt 4 will bear the main impact force. As the impact force increases, the first fracture 411 will break, releasing the third connecting section 44, thereby dispersing the impact force and reducing its peak value. If the impact force is still too large, the second fracture 461 will break, releasing the folding portion 45. The multi-layer structure of the folding portion 45 can further absorb the impact force, while increasing the falling time and reducing the acceleration, thereby reducing the damage to the staff. At the same time, during the entire falling process, the combination of the spring and the rotating drum will continue to provide resistance and control the falling speed, so that the staff can land more smoothly and avoid injuries caused by the sudden fall.

[0064] Furthermore, after the multiple buffer mechanisms fail to effectively buffer, the rapid movement of the high-strength belt 4 will drive the movable wedge 54 to move downward, causing the spacing 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, and at the same time, the part of the movable wedge 54 that is ejected drives the support protrusion 65 to move, thereby driving the installation member 6 to move. When the installation member 6 moves, since the third inclined surface 631 of the push wedge 63 contacts 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 causing the ratchet 35 to combine with the ratchet teeth 361 and interact to prevent the rotation of the drum, thereby achieving an emergency stop action for the high-strength belt 4. The locking mechanism can prevent rapid and uncontrolled descent caused by unexpected situations (such as the fall of a worker), thereby providing a certain safety buffer.

[0065] In summary, the safety belt suspension structure based on the maintenance of substation power equipment effectively prevents injuries caused by emergency situations such as falling during the maintenance process of workers through real-time monitoring of height changes, multiple buffer mechanisms and the synergy of the emergency braking system, providing comprehensive and reliable safety protection.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
