Description
Technical Field
[0001] This utility model relates to the field of power operation technology, and in particular to a convenient protective storage device for insulating blankets. Background Technology
[0002] At power construction sites, there are high-voltage equipment, exposed wires, or other electrical components. Laying insulating blankets can effectively isolate personnel from direct contact with the power source, preventing leakage or electric shock accidents caused by current passing through the human body. As an insulating material, insulating blankets can effectively prevent the flow of current, forming an insulating layer for protection. This can reduce the current passing through the ground or other conductors, reducing the risk of electric shock.
[0003] Currently, traditional storage methods for insulating blankets often involve folding them and placing them in ordinary cloth bags or cardboard boxes. This process is cumbersome and time-consuming. In scenarios requiring rapid response, such as power emergency repairs, the folding and unfolding process consumes a significant amount of emergency time, severely impacting work efficiency. Furthermore, it is difficult to adapt to the mobility needs of complex working environments such as outdoor, high-altitude, and confined spaces. At the same time, ordinary storage devices lack effective protective structures, making it difficult to resist physical friction, punctures, and other damage during transportation and storage. They also cannot effectively prevent the corrosion of environmental factors such as dust, moisture, and ultraviolet rays, leading to problems such as wear, aging, and decreased insulation performance of the insulating blankets. This not only shortens their service life but also poses significant safety hazards. Utility Model Content

Detailed Implementation Example 1:
[0026] like Figures 1-3 As shown, a portable protective storage device for insulating blankets includes a winding cylinder 1, a protective blanket 2, and a carrying strap assembly 4. One end of the protective blanket 2 is connected to the winding cylinder 1. The front of the protective blanket 2 is provided with a first hook and loop fastener 21 for fixing the insulating blanket 3, and the back of the insulating blanket 3 is provided with a first hook and loop fastener hook surface 31 that is adapted to the first hook and loop fastener 21. The carrying strap assembly 4 is connected to the protective blanket 2 or the winding cylinder 1. The front and back of the protective blanket 2 are respectively provided with a second hook and loop fastener 22 and a second hook and loop fastener hook surface 23 at corresponding positions.
[0027] In this embodiment, the traditional folding and storage method of the insulating blanket is optimized into a roll-up method by using the roll-up cylinder 1. With the quick adaptation and fixation of the first Velcro loop side 21 on the front of the protective blanket 2 and the first Velcro hook side 31 on the back of the insulating blanket 3, the positioning and attachment of the insulating blanket 3 and the protective blanket 2 can be completed without tools, which greatly shortens the operation time of unfolding and storage. This effectively solves the problem that folding and unfolding take up a lot of emergency time and affects the work efficiency in the prior art. The carrying strap component 4 facilitates carrying or hand carrying, flexibly adapting to the movement needs of complex environments such as outdoors, high altitudes and confined spaces, making up for the shortcomings of the prior art in adapting to the movement needs of complex scenarios. At the same time, the protective blanket 2 can form a complete wrapping protection for the insulating blanket 3, preventing the insulating blanket 3 from directly contacting the external environment, reducing the risk of wear and aging, and ensuring its stable insulation performance. This solves the problem that the insulating blanket is easily worn and aged, resulting in a decline in insulation performance in the prior art. In addition, the second Velcro loop side 22 and the second Velcro hook side 23 on the front and back of the protective blanket 2 can be quickly attached and fixed after rolling, ensuring the stability of the rolled state and further improving the reliability of carrying in complex environments.
[0028] like Figure 1 and Figure 2 As shown, the width of the protective blanket 2 is greater than the width of the insulating blanket 3.
[0029] In this embodiment, the protective blanket 2 is wider than the insulating blanket 3, so that after the protective blanket 2 is attached to the insulating blanket 3, its two side edges can naturally extend beyond the sides of the insulating blanket 3. When the device is rolled up or carried, the extended part can completely wrap the sides of the insulating blanket 3, forming an all-round physical protective barrier. This prevents the sides of the insulating blanket 3 from directly colliding or rubbing against external hard objects, or from coming into contact with corrosive environments such as dust and moisture, effectively reducing the risk of side wear and aging, and thus ensuring the stable insulation performance of the insulating blanket 3. At the same time, the wider protective blanket 2 can form a lateral limit on the insulating blanket 3 through the extended sides during the rolling process, preventing the insulating blanket 3 from shifting or deviating laterally during rolling, and ensuring that the overall structure is compact and neat after rolling.
[0030] like Figure 1 and Figure 2 As shown, the second hook and loop side 22 and the second hook and loop side 23 are both located at the end of the protective blanket 2 away from the winding drum 1.
[0031] In this embodiment, the second hook and loop side 22 and the second hook and loop side 23 are both located at the end of the protective blanket 2 away from the winding cylinder 1. This position is the free end of the protective blanket 2 after it is rolled up. After the roll-up is completed, the hook and loop at this position can be directly attached, which can accurately lock the end structure after the roll-up. It can form an effective fixation from the free end of the roll-up, preventing the protective blanket 2 and the insulating blanket 3 from loosening and falling apart as a whole after the roll-up, ensuring the stability of the storage state. It is especially suitable for carrying in bumpy environments such as outdoors and at high altitudes. At the same time, the hook and loop position away from the end of the winding cylinder 1 will not interfere with the winding cylinder 1 when unfolding or rolling up. There is more operating space, and the staff can quickly complete the hook and loop attachment and fixation after the roll-up. When needed, the hook and loop can be torn open with one click to unfold without additional adjustment of the position of the winding cylinder 1.
[0032] like Figure 1 and Figure 2 As shown, the second hook and loop side 22 extends along the width direction of the protective blanket 2, and the second hook and loop side 23 extends along the length direction of the protective blanket 2.
[0033] In this embodiment, the second hook and loop fastener 22 extends along the width of the protective blanket 2, covering the transverse cross-section of the free end of the protective blanket 2 after it is rolled up. The second hook and loop fastener 23 extends along the length of the protective blanket 2, adapting to the longitudinal bonding requirements of different layers after rolling up. The two extend in opposite directions to form a locking structure that provides transverse coverage and longitudinal adjustment. Compared with hook and loop fasteners that extend in a single direction, the contact area is larger and the force is more even when bonding. This effectively prevents the protective blanket 2 and the insulating blanket 3 from becoming loose in the circumference or shifting in the axial direction during carrying. It is especially suitable for carrying in complex working environments such as outdoor bumps and high-altitude swaying. At the same time, the second hook and loop fastener 22 extending along the width direction and the second hook and loop fastener 23 extending along the length direction allow the hook and loop fastener bonding position to be flexibly adjusted according to the tightness of the roll-up. Stable bonding can be achieved without precise alignment. Workers can quickly complete the roll-up and fixation in emergency work scenarios, further saving operation time. It can also adapt to the roll-up requirements of insulating blankets 3 with different thicknesses, avoiding the problem of hook and loop fasteners not being able to bond due to changes in roll-up thickness.
[0034] like Figure 1 and Figure 4 As shown, memory soft steel wires 25 are threaded through both sides of the protective blanket 2.
[0035] In this embodiment, the memory steel wires 25 threaded along the two sides of the protective blanket 2 have excellent shape-memory function. When unfolded, they can quickly return to a flat state due to their own elasticity, keeping the two sides of the protective blanket 2 straight. There is no need for staff to tidy up wrinkles or adjust the shape. It can be laid flat directly and quickly and accurately attached to the insulating blanket 3 through the first Velcro. This effectively solves the problem of traditional insulating blankets requiring repeated smoothing and tidying, which takes up a lot of emergency time. It meets the rapid response requirements of emergency operations. At the same time, the two sides of the protective blanket 2 after being shaped by the memory steel wires 25 form a rigid support, which can effectively resist the collision and compression of the sides of the insulating blanket 3 by external hard objects. It can prevent the sides of the insulating blanket 3 from being worn and deformed due to direct force. Combined with the design that the width of the protective blanket 2 is greater than that of the insulating blanket 3, a dual side protection structure of flexible wrapping and rigid protection is formed, which reduces the aging and insulation performance degradation of the insulating blanket 3 caused by side damage and extends its service life.
[0036] like Figure 4 and Figure 5 As shown, the shoulder strap assembly 4 includes a first drawstring 41 and a second drawstring 42. The first drawstring 41 and the second drawstring 42 are connected to the protective blanket 2 at the end near the winding shaft 1, and the first drawstring 41 and the second drawstring 42 are respectively arranged in the drawstring channels 24 on both sides of the protective blanket 2.
[0037] In this embodiment, by adopting the structural design of the first drawstring 41 and the second drawstring 42, the length of the drawstrings can be freely adjusted to adapt to the height and carrying habits of different workers, flexibly realizing multiple carrying methods such as hand-carrying, shoulder carrying, or crossbody carrying. This perfectly meets the mobility needs of complex working environments such as outdoors, high altitudes, and confined spaces, effectively solving the problem of the traditional insulation blanket's single carrying method and its difficulty in adapting to complex working scenarios. The first drawstring 41 and the second drawstring 42 are respectively inserted into the drawstring channels 24 on both sides of the protective blanket 2. The drawstring channels 24 can stably limit and store the drawstrings, preventing the drawstrings from swinging randomly or getting tangled during carrying or unfolding and rewinding of the insulation blanket 3. This keeps the device clean and avoids the drawstrings interfering with core operations such as Velcro fastening and the rotation of the rewinding cylinder 1, further saving emergency operation time.
[0038] The protective blanket 2 has a drawstring 41 and a drawstring 42 symmetrically inserted into the drawstring channels 24 on both sides. Pulling the drawstrings and locking them with the first male buckle 43 and the first female buckle 44 will generate a uniform inward restraint force on both sides of the protective blanket 2. Combined with the design that the width of the protective blanket 2 is greater than that of the insulating blanket 3, it can drive the side of the protective blanket 2 beyond the insulating blanket 3 to fit inward and closely contact the side of the insulating blanket 3, forming a sealed wrapping of both sides of the insulating blanket 3. This effectively prevents external dust and moisture from seeping in from the gaps on both sides, solving the problem of gaps easily left on both sides and incomplete protection in the traditional rolling method.
[0039] like Figure 4and Figure 5 As shown, one end of the first drawstring 41 is provided with a first male buckle 43, and one end of the second drawstring 42 is provided with a first female buckle 44 that is compatible with the first male buckle 43.
[0040] In this embodiment, a snap-fit quick connection is achieved through the first male buckle 43 and the first female buckle 44. Workers can complete the fixing and separation of the drawstring without complicated operations. Compared with the traditional drawstring knot fixing method, it avoids the emergency time occupied by knotting and untying, effectively meeting the needs of rapid preparation and rapid transfer in emergency operations. Through the precise engagement structure of the first male buckle 43 and the first female buckle 44, the first drawstring 41 and the second drawstring 42 can form a stable ring carrying structure, preventing the drawstring from accidentally loosening or falling off during carrying, which would cause the device to slip. Especially in complex scenarios such as high-altitude climbing, outdoor walking, or moving in confined spaces, it can ensure that the protective blanket 2 and the insulating blanket 3 are stably attached after being rolled up, avoiding displacement and wear of the insulating blanket 3 due to shaking or collision. This solves the defects of traditional carrying methods that are easy to loosen and difficult to adapt to the needs of moving in complex environments.
[0041] like Figure 4 and Figure 5 As shown, rope loops 5 are provided on both sides of the protective blanket 2 near the end of the winding drum 1.
[0042] In this embodiment, the rope loops 5 provided on both sides of the protective blanket 2 near the end of the winding drum 1 can serve as additional connection and suspension structures. They can be used with hooks, safety ropes and other components to temporarily suspend and store the device on high-altitude work platforms, outdoor supports and other locations, avoiding moisture and wear of the insulating blanket 3 caused by ground placement. They can also be used with the first draw rope 41 and the second draw rope 42 to form a multi-point force-bearing structure, which is suitable for special scenarios such as high-altitude climbing and transportation in confined spaces. Example 2:
[0043] like Figure 6 and Figure 7 As shown, the shoulder strap assembly 4 includes a first webbing 45 and a second webbing 46. The first webbing 45 is connected to one end of the winding cylinder 1, and the second webbing 46 is connected to the other end of the winding cylinder 1. A second male buckle 47 is connected to one end of the first webbing 45, and a second female buckle 48 that is adapted to the second male buckle 47 is provided at one end of the second webbing 46.
[0044] In this embodiment, the symmetrical structure connecting the two ends of the winding cylinder 1 via the first webbing 45 and the second webbing 46 ensures that the tension during carrying is evenly distributed across the axial ends of the winding cylinder 1, preventing the device from tilting or swaying due to concentrated force. The second male buckle 47 at one end of the first webbing 45 and the matching second female buckle 48 at one end of the second webbing 46 adopt a snap-on quick connection design, allowing workers to fasten and detach the straps without tools, thus meeting the needs for rapid transfer and preparation, and further solving the problems of time-consuming operation and low efficiency in the prior art.
[0045] Specifically, the webbing material has stronger wear resistance and tensile strength than ordinary drawstrings, and can withstand the wear and tear caused by friction and pulling in outdoor and high-altitude operations. Combined with the stable locking structure of the second male buckle 47 and the second female buckle 48, it can effectively prevent the strap from breaking or falling off during carrying, and is suitable for the transportation needs of complex operation scenarios such as high-altitude climbing and long-distance outdoor movement. At the same time, the direct connection between the webbing and the winding cylinder 1 reduces intermediate stress nodes, further improving the structural stability of the strap assembly 4 and extending the service life of the entire device.
[0046] like Figure 6 and Figure 7 As shown, the first webbing 45 and the second webbing 46 are connected to a fixing strap 49 near one end of the winding cylinder 1. One end of the fixing strap 49 is connected to a fixing male buckle 410. The back of the protective blanket 2 is provided with a fixing female buckle 411 that is compatible with the fixing male buckle 410.
[0047] In this embodiment, the fixing strap 49 connected to the first webbing 45 and the second webbing 46 near the end of the winding drum 1 is precisely engaged with the fixing female buckle 411 adapted to the back of the protective blanket 2 through the fixing male buckle 410 at one end, forming a double fixing structure of the webbing and the winding drum 1 and the webbing and the protective blanket 2. Compared with the single fixing method that only connects the webbing to the winding drum 1, it effectively avoids the webbing from shifting due to shaking and pulling during carrying, ensuring that the carrying strap assembly 4 is firmly connected to the main body of the device. Even in complex scenarios such as high-altitude climbing and rapid transfer, it can prevent the device from tilting or loosening, further ensuring the carrying safety of the insulating blanket 3.
[0048] Working principle: Before use, the first Velcro loop side 21 on the front of the protective blanket 2 is precisely attached to the first Velcro hook side 31 on the back of the insulating blanket 3, achieving quick fixation of the insulating blanket 3 and the protective blanket 2. The protective blanket 2 is wider than the insulating blanket 3, allowing for pre-wrapping protection of the insulating blanket 3 on its sides. Simultaneously, the memory steel wires 25 along both sides of the protective blanket 2 maintain its shape, facilitating quick and easy unfolding. During storage, using the winding drum 1 as the core carrier, the free end of the protective blanket 2 away from the winding drum 1 is pulled, causing the insulating blanket 3 to be wound up synchronously. The memory steel wires 25 assist in the neat winding of the protective blanket 2. After winding, the protective blanket 2 is unwound along its free end... The second Velcro loop 22 extending in the width direction and the second Velcro hook 23 extending in the length direction cross and fit together to lock the roll-up state. Then, the first drawstring 41 and the second drawstring 42 are pulled and tightened. The first male buckle 43 and the first female buckle 44 are quickly fastened, so that the drawstrings exert an inward restraining force on both sides of the protective blanket 2, achieving a tight seal on both sides after roll-up. At the same time, the rope loops 5 on both sides of the protective blanket 2 near the end of the roll-up cylinder 1 can be used to assist in roll-up, temporary suspension, or enhance carrying stability. When carrying, the length of the first drawstring 41 and the second drawstring 42 can be adjusted to flexibly achieve hand carrying, shoulder carrying, or crossbody carrying, adapting to different work scenarios.
