Description
Technical Field
[0001] The invention relates to the technical field of electric power repair tools, and in particular to a quick-expanding and storable insulating shielding device. Background Art
[0002] In the daily maintenance and precision operation of high-voltage power distribution equipment, power technicians often face multiple challenges, especially the highly dangerous working environment, space limitations, and compact layout of distribution facilities. These factors not only increase the risk of electric shock accidents, but also make the existing insulating protective equipment insufficient when performing critical electrical isolation and safety protection. Although traditional insulating protective clothing and gloves can provide necessary protection for operators to a certain extent, they are usually made of insulating rubber materials with poor air permeability, which can easily cause the wearer to sweat and feel stuffy. This greatly affects work efficiency and work safety in an already cramped and hot working environment.
[0003] In addition, as an indispensable part of electrical isolation operations, the unfolding and fixing process of the insulation blanket also has many inconveniences. Usually, the laying and positioning of the insulation blanket requires the coordinated operation of both hands, and relies on tools such as clamps to stabilize the position. This process is particularly cumbersome and difficult in high-altitude operations or in environments with limited space. More importantly, such complex operations not only prolong the operation time, but may also pose safety hazards due to operational errors or inconveniences, posing a potential threat to the life safety of power technicians. Therefore, in view of the particularity of the operating environment of high-voltage power distribution equipment, it is particularly important to develop a lighter, more efficient and easy-to-deploy insulation protection solution.
[0004] In existing research, there have been many achievements on this issue. For example, patent application number CN202411097434.8 discloses an insulating isolation blanket, which relates to the field of insulating blanket technology. The insulating isolation blanket consists of a first protective layer, a second protective layer and an intermediate layer, and the intermediate layer is a thin layer structure. One side of the insulating blanket is evenly provided with a plurality of insulating bags, with built-in magnets, and a plurality of through fixing holes are provided at the upper and lower ends for fixing the insulating blanket to an object that needs to be insulated. In addition, a plurality of connection holes are evenly provided on the left and right sides of the insulating blanket.
[0005] Another study, patent application number CN202211211594.1, discloses an insulating blanket and its working method for 0.4kV low-voltage non-stop operation. The insulating blanket is provided with a plurality of mounting grooves along the edge in the length direction, and an insulating shell is fixed in the groove, and a magnetic block is provided in the shell. When in use, multiple sets of insulating clips can be clamped on the edge of the low-voltage cabinet and the edge of the cabinet door respectively to ensure that the insulating blanket fits tightly to the electronic components inside the low-voltage cabinet, thereby ensuring the power insulation properties and the safety of the staff. However, these two technologies cannot be used in a relatively narrow working space and can only be used in specific setting scenarios, which is not convenient for operators to carry with them. Summary of the invention
[0006] In view of the above problems, it is necessary to develop a tool that improves the efficiency of deployment and reception of insulation blankets, which saves a lot of deployment and reception time for users who frequently move work areas.
[0007] Therefore, the present application proposes a quick-expanding and storage insulating shielding device, comprising an insulating blanket and a folding and storage system installed on the insulating blanket, wherein the folding and storage system is used to quickly expand and store the insulating blanket, so that the insulating blanket can be quickly switched between a rod-shaped storage form and a sheet-shaped expanded form.
[0008] The folding and storing system comprises a fixed rod, a first folding rod, a second folding rod and a nesting. The fixed rods are fixedly installed on the end faces at both ends in the length direction of the insulation blanket. When the insulation blanket is fully unfolded along the length direction, the two fixed rods are parallel to each other. The first folding rod and the second folding rod are respectively rotatably installed on one end in the same direction of the two fixed rods. A nesting is fixedly installed on one end of each of the first folding rods away from the hinge point between the first folding rod and the fixed rod. Each nesting is hinged to the corresponding second folding rod. When the insulation blanket is fully unfolded along the length direction, the first folding rod and the second folding rod on the same side form an angle of 180 degrees.
[0009] Preferably, the nesting is a double-layer groove structure, the first layer structure is a straight groove with holes at both ends, and the straight groove is installed in cooperation with the first folding rod; the second layer structure is a side-opening straight groove with a side opening, and the side-opening straight groove is installed in cooperation with the second folding rod, and when the insulating blanket is fully unfolded along the length direction, the second folding rod on the same side is rotated to form an angle of 180 degrees with the side-opening straight groove.
[0010] Preferably, the opening directions of the two side-opening straight grooves are facing away from each other.
[0011] Preferably, the two nested end faces are provided with magnetic blocks that attract each other, and the two nested end faces are both provided with avoidance cut surfaces. When the second folding rod is rotated to form an angle of 0 degrees with the side opening straight groove, the two avoidance cut surfaces fit each other.
[0012] Preferably, each of the side-opening straight grooves is provided with an elastic convex ball protruding from the inner wall, and each of the second folding rods is provided with a pit adapted to the shape of the elastic convex ball. When the second folding rod is rotated to form an angle of 180 degrees with the side-opening straight groove, the elastic convex ball is embedded in the corresponding pit to limit the relative rotation of the second folding rod and the side-opening straight groove.
[0013] Preferably, the two cut surfaces are provided with mortise and tenon grooves which can fit into each other when the second folding rod is rotated to form an angle of 0 degrees with the side opening straight groove.
[0014] Preferably, the insulating blanket is made of EVA material, and the edges thereof are sealed by hot-melt.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The solution proposed in this case can effectively improve the efficiency of deployment and reception of insulation blankets, saving a lot of deployment and reception time for users who frequently move work areas.
[0017] 2. The unfolding and folding mechanism of the scheme proposed in this case is easy to operate. The insulation blanket can be unfolded and received through simple push-pull actions, which reduces the physical burden of the operator and improves the working efficiency, especially in a narrow environment or an environment where it is inconvenient to use both hands for operation.
[0018] 3. After receiving, the insulation blanket can be rolled into a roll, which does not take up extra space and is convenient for receiving and transferring. At the same time, the device is equipped with an additional receiving belt to prevent the insulation blanket from being scratched or pierced by other tools when storing or taking it out. It effectively increases the service life of the insulation blanket. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] The following is combined with Figure 1 To Attachment Figure 3 The present invention proposes a quick unfolding and storage insulating shielding device, comprising an insulating blanket 5 and a folding and storage system installed on the insulating blanket 5, wherein the folding and storage system is used to quickly unfold and store the insulating blanket 5, so that the insulating blanket 5 can be quickly switched between a rod-shaped storage form and a sheet-shaped unfolding form.
[0026] The folding storage system includes a fixed rod 1, a first folding rod 2, a second folding rod 3 and a nesting 4. The fixed rods 1 are fixedly installed on the end faces of both ends of the insulation blanket 5 in the length direction. When the insulation blanket 5 is fully unfolded in the length direction, the two fixed rods 1 are parallel to each other. The first folding rod 2 and the second folding rod 3 are respectively rotated and installed at the same end of the two fixed rods 1. Each of the first folding rods 2 is fixedly installed with a nesting 4 at one end away from the hinge point between the first folding rod 2 and the fixed rod 1. Each nesting 4 is hinged to the corresponding second folding rod 3. When the insulation blanket 5 is fully unfolded in the length direction, the first folding rod 2 and the second folding rod 3 on the same side form an angle of 180 degrees. The fixed rod 1 can be a groove-shaped structure, and the insulation blanket 5 is pressed into the groove-shaped structure by the clamping member 6 to achieve fixation.
[0027] The nesting 4 is a double-layer groove structure, the first layer structure is a straight groove with holes at both ends, and the straight groove is installed in cooperation with the first folding rod 2; the second layer structure is a side-opening straight groove with side openings, and the side-opening straight groove is installed in cooperation with the second folding rod 3. When the insulating blanket 5 is fully unfolded along the length direction, the second folding rod 3 on the same side rotates to form an angle of 180 degrees with the side-opening straight groove. This design can make the structure formed by the two fixed rods 1 and the first folding rod 2 and the second folding rod 3 after contraction closer to 1:1 in aspect ratio, which is more convenient to carry than the sheet-like structure.
[0028] The opening directions of the two side-opening straight grooves are facing back to back, and when they are fully opened, they can form an outward pulling force, so that the entire insulation blanket 5 is in a stretched state.
[0029] The end faces of the two nests 4 are provided with mutually attractive magnetic blocks 7, and the end faces of the two nests 4 are provided with avoidance cut surfaces. When the second folding rod 3 is rotated to form an angle of 0 degrees with the side opening straight groove, the two avoidance cut surfaces are fitted together, and the mutually attractive magnetic blocks 7 make the end faces of the two nests 4 fit together. The two avoidance cut surfaces fit together to increase the area of magnetic adsorption. Compared with straight surfaces, such high matching accuracy is not required, which reduces the processing difficulty.
[0030] Each of the side-opening straight grooves is provided with an elastic convex ball protruding from the inner wall, and each of the second folding rods 3 is provided with a pit adapted to the shape of the elastic convex ball. When the second folding rod 3 is rotated to form an angle of 180 degrees with the side-opening straight groove, the elastic convex ball is embedded in the corresponding pit to limit the relative rotation of the second folding rod 3 and the side-opening straight groove. The structure is similar to the elastic block structure on the telescopic joint of an umbrella, forming a self-locking structure to avoid contraction during use.
[0031] The two sections are provided with mortise and tenon grooves which can engage with each other when the second folding rod 3 is rotated to form an angle of 0 degrees with the side opening straight groove. The mutually engaged mortise and tenon grooves can improve the fit after winding, reduce the clearance gap, and avoid friction and abnormal noise during transportation.
[0032] The insulating blanket 5 is made of EVA material, and the edges are sealed by hot-melt. The blanket surface made of EVA material can be thin and light, with a thickness of about 1-2.5 mm, good toughness and tear resistance. During production, hot bonding is often used, that is, the EVA insulating cloth is cut into a predetermined size and the whole is produced by hot-melt sealing, and the processing can be an embedded design.
