Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, and in particular to a power safety network support structure suitable for complex terrain. Background Technology

[0002] Power safety nets are specialized devices for power operations and equipment protection. Their main function is to physically isolate live equipment or dangerous areas, preventing personnel from accidentally touching or colliding with live parts and causing electric shock accidents. They can also block foreign objects (such as branches, birds, and debris) from entering the equipment, avoiding short circuits, equipment damage, and other malfunctions. In addition, they can also serve as temporary protective devices to delineate safe areas during maintenance work, providing a direct and reliable safety barrier for personnel and equipment.

[0003] A search revealed that the document with publication number "CN219491792U" states that "this utility model discloses a safety net support frame, relating to the field of safety net supports, including a first support rod, the bottom of which is provided with a telescopic structure; a second support rod is provided at the top of the first support rod, and a third support rod is provided at the top of the second support rod.

The telescopic structure includes: a first fixing ring fixedly sleeved on the middle of the outer surface of the first support rod, and a plurality of first hinge seats arranged in a ring on the outer surface of the first fixing ring; one end of each of the first telescopic rods is hinged to the first hinge seat; a second fixing ring fixedly sleeved on the bottom of the outer surface of the first support rod, and a plurality of second hinge seats arranged in a ring on the outer surface of the second fixing ring; one end of each of the second telescopic rods is hinged to the second hinge seat. The telescopic structure can provide support." In use, the fixed rod allows the device to adapt to various ground environments while providing support and fixation.

[0004] However, during power maintenance, the working environment often involves complex terrain such as slopes, gullies, and vegetation cover. Conventional support structures are mostly adapted to flat terrain, and their support stability is poor in complex environments. Furthermore, due to the rugged ground, it is difficult to adjust the height of the power safety net, resulting in poor deployment of the safety net and affecting the protection range and work safety.

[0005] Therefore, we provide a power safety network support structure suitable for complex terrain to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 As shown, this utility model provides a technical solution: a power safety net support structure suitable for complex terrain, including a support base 1, a counterweight block 2 connected to the inner side of the support base 1, safety net support components 5 at the four corners of the support base 1, the safety net support components 5 including driven shaft brackets 501 welded to the four corners of the support base 1, side support brackets 502 installed on the inner side of the driven shaft brackets 501, a net installation connection component 6 provided on the upper side of the support base 1, the net installation connection component 6 including an upper threaded groove 601 welded to the middle of the upper side of the support base 1, a threaded head 602 threadedly connected to the upper side of the upper threaded groove 601, a lower telescopic rod 603 welded to the upper side of the threaded head 602, an upper telescopic rod 604 installed on the inner side of the lower telescopic rod 603, a telescopic limit screw 605 provided on the outer side of the lower telescopic rod 603, and a power safety net 7 provided in the middle of the lower telescopic rod 603.

[0019] Furthermore, the counterweight 2 and the support base 1 are connected by a slot. The counterweight 2 is made of metal. The counterweight 2 and the support base 1 form a planar structure. When used in mountainous or uneven terrain, the counterweight 2 is embedded into the slot of the support base 1, thereby increasing the stability of the support base 1 and preventing the support base 1 from overturning due to a large tilt. When the weight of the counterweight 2 is insufficient, heavy objects such as stones can be placed on the counterweight 2 to further enhance the overall stability.

[0020] Furthermore, a lower threaded groove 3 is provided in the middle of the lower side of the support base 1. The inner thread of the lower threaded groove 3 is connected to a soil-entry cone 4. When used on soil-covered terrain, the soil-entry cone 4 is screwed into the lower threaded groove 3, and then driven into the ground by hammering or pressing to enhance the anchoring force between the soil-entry cone 4 and the ground, thereby effectively preventing the support base 1 from slipping or overturning.

[0021] Furthermore, the side support legs 502 and the driven shaft frame 501 form a rotating structure. The end of the side support legs 502 is provided with a leg positioning claw 503. There are four sets of side support legs 502, which are evenly distributed. When needed, the four sets of side support legs 502 are unfolded outward and rotated to a suitable angle for support. If it is a mountainous or sloping location, the unfolding angle of the side support legs 502 can be adjusted so that the leg positioning claw 503 is inserted into the ground as a support point to enhance the overall stability.

[0022] Furthermore, a spring tension rod 504 is provided on the lower side of the driven shaft bracket 501, and a spring traction rod 505 is welded to the lower side of the side support bracket 502. A traction spring 506 is connected between the spring traction rod 505 and the spring tension rod 504. The traction spring 506 drives the side support bracket 502 to cooperate with the driven shaft bracket 501 to form an elastic inward retraction structure. When the side support bracket 502 is unfolded, the traction spring 506 drives the side support bracket 502 to pull inward through the spring tension rod 504 and the spring traction rod 505, thereby strengthening the grip of the side support bracket 502 and adapting to more terrain changes.

[0023] Furthermore, the upper telescopic rod 604 and the lower telescopic rod 603 are connected by a slot. The upper telescopic rod 604 and the lower telescopic rod 603 form a limiting telescopic structure through the telescopic limiting screw 605. When needed, the relative length of the upper telescopic rod 604 and the lower telescopic rod 603 can be adjusted according to the terrain changes. Finally, the length is fixed by the telescopic limiting screw 605 to adapt to different height requirements.

[0024] Furthermore, a safety net height adjusting collar 606 is connected to a groove on the surface of the upper telescopic pole 604. A collar rotating ring 607 is connected to the middle groove on the outer side of the safety net height adjusting collar 606. A rotating ring hook 608 is welded to the outer side of the collar rotating ring 607. The safety net height adjusting collars 606 are evenly distributed. The power safety net 7 is connected in series through the rotating ring hook 608. When needed, the power safety net 7 can be fixed to the rotating ring hook 608. According to the required shielding direction of the power safety net 7, the collar rotating ring 607 can be rotated along the safety net height adjusting collar 606 to adjust the orientation of the rotating ring hook 608, thereby adjusting the coverage angle of the power safety net 7. According to the power operation height requirements, the position of the safety net height adjusting collar 606 on the upper telescopic pole 604 can be adjusted to adjust the height of the traction point of the power safety net 7.

[0025] Working principle: When needed, first fix the soil-inserting cone 4 to the lower side of the support base 1 through the lower threaded groove 3. Then, place the support base 1 in the desired position and embed the load-bearing counterweight 2 into the support base 1. Subsequently, according to the slope of the ground, extend the four sets of side support legs 502 outward through the driven shaft bracket 501. At this time, the spring tension rod 504 and the spring traction rod 505 drive the side support legs 502 to retract inward through the traction spring 506, thereby gripping the soil-positioning claws 503 onto the ground. After fixing, place counterweights such as stones on the load-bearing counterweight 2 to increase the counterweight. After fixing, adjust the weight according to the ground height. Under the given conditions, the lower telescopic rod 603 is fixed in the upper threaded groove 601 through the threaded head 602. The height of the upper telescopic rod 604 is adjusted according to the height requirements, and then fixed with the telescopic limit screw 605. After fixing, the height adjustment collar 606 of the safety net is adjusted along the upper telescopic rod 604 and the lower telescopic rod 603. Finally, the power safety net 7 is fixed to the rotating ring hook 608. According to the actual unfolding direction, the rotating ring hook 608 can be rotated through the collar rotating ring 607 to achieve the purpose of direction adjustment. This completes the use process of a power safety net support structure suitable for complex terrain.
