Safety surrounding net for transformer substation maintenance

Abstract

The invention discloses a safety surrounding net for transformer substation maintenance, and belongs to the technical field of safety surrounding nets. The safety surrounding net comprises a fence surrounding body and inserting rod devices arranged at the two ends of the fence surrounding body, the fence surrounding body comprises a fence surrounding main body capable of being folded and stored in a screen mode, a first panel and a second panel are correspondingly arranged at the two ends of the fence surrounding main body, and a steel wire rope controlled by an automatic winder penetrates through the safety surrounding body and can be folded. The safety surrounding net for transformer substation maintenance is high in universality and can be directly used in cooperation with the inserting rod most commonly used in a transformer substation at present, a large number of inserting rods arranged in the transformer substation do not need to be replaced again, cost is saved, and popularization difficulty is lowered; the inserting rod comprises an outer barrel, an adjusting rod, a fixing sleeve, a flange plate, three sets of arc-shaped variable-diameter plates distributed in a circumferential array mode, an upper connecting rod and a lower connecting rod are arranged in the outer barrel, the three sets of arc-shaped variable-diameter plates can be directly controlled to move by rotating a rotary knob, the inserting rod can be inserted and fixed in different hole diameters, and other reinforcing anti-loosening structures can be eliminated.

Description

technical field [0001] The invention relates to the technical field of safety fences, in particular to a safety fence for substation maintenance. Background technique [0002] At present, safety fences are widely used in the production line, such as: substations, construction sites, construction sites, etc. Among them, the daily maintenance work of the substation is inseparable from the safety fence. When a certain equipment or interval in the substation needs to be powered off for maintenance, corresponding safety measures need to be taken, and the safety fence is the most basic safety measure. The layout of the safety fence can isolate the live part from the uncharged part, prevent people from entering the live compartment by mistake, prevent people from entering the dangerous area by mistake, and largely guarantee the safety of the staff. [0003] At present, there are two kinds of safety fences generally used. 1. Fishing net type: It is made of nylon rope into a net s...

Problems solved by technology

However, during the storage process, it is easy to curl up and cause storage failure, so the storage is also more complicated and difficult, and the storage time is too long and cumbersome

After being rolled up, it is bulky and bulky, which is not conducive to handling and storage

[0005] The length of the traditional safety fence is fixed and uniform, but the distance between the insertion rods on the job site is different. In addition, the diversification of work tasks leads to a variety of distances between the insertion rods. Therefore, the safety fence with a fixed length Seines are often difficult to meet the needs of the job site

The length of the reel type and fishing net type seine is fixed, and it is easy to produce redundant parts drooping on the insertion rod during installation, which affects the isolation effect and the work of on-site personnel. The fishing net type seine is too light in weight and loose in structure. It is also easy to be blown up by the wind, which poses a safety hazard

[0006] Although the traditional fishing net safety net has a certain degree of ductility, the ductility is very small. When the length of the seine net is lower than the distance between the insertion poles, the staff can only use ropes to tie multiple seine nets together to increase the net length. length

However, this solution not only increases the complexity and difficulty of installation and disassembly, but also wastes a lot of time and greatly reduces work efficiency.

When the fence is longer than the distance between the inserting rods, the fence cannot be straightened due to the soft texture of the fence, which will cause the fence to sag and affect the isolation effect

[0007] In addition, the inserting rods commonly used in existing safety fences are generally specific types of inserting rods, that is, the diameter of the inserting rod is fixed, and can only be applied to the same size of the socket, and generally require other auxiliary equipment after insertion. The fixed mechanism supports fastening. However, in the actual application process, it is found that the hole diameters of the seine sockets near different equipment in the substation are often inconsistent, which leads to the need to equip insertion rods with various diameters for replacement.

As a result, the construction equipment that needs to be carried is relatively large and heavy, which is not conducive to handling and storage
