Description

Technical Field

[0001] This utility model relates to the field of power auxiliary accessories technology, specifically to a substation protection screen roller shutter-type red cloth curtain device. Background Technology

[0002] Substation electrical equipment requires periodic power outages for maintenance and other tasks. During this time, some electrical control cabinets cease operation, awaiting maintenance, while others remain operational. To prevent staff from mistakenly identifying normally functioning control cabinet protective panels as outage panels and thus misoperating, red cloth curtains are often hung on the protective panels for concealment.

[0003] Traditional red drapes are typically rolled up by a roller shutter box when not in use, and stretched to a predetermined length for coverage when needed. However, the drawback of this traditional method is that it only allows for vertical adjustments in height or length; horizontal adjustments are limited by the length of the roller shutter box. This results in red drapes being redundant for displays that are too small, and failing to completely cover displays that are too large.

[0004] In view of this, improvements are needed to address the aforementioned deficiencies. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a roll-up red curtain device for substation protection screens, thereby solving the problem that the red curtain in the prior art cannot be adjusted according to the actual width of the protection screen it covers.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a substation protection screen roller shutter type red cloth curtain device, comprising: two outer shells, the two outer shells being symmetrically arranged; a winding roller, each of the outer shells being rotatably connected to a winding roller; a red cloth curtain, the red cloth curtain being wound on the winding roller; and an adjustment component, the adjustment component being disposed on one side of the two outer shells that are close to each other, the adjustment component comprising two nested sleeves.

[0007] Optionally, one of the sleeves is fitted over the other sleeve, and the outer periphery of the two sleeves, which are close to each other, is threadedly connected to a screw cap, and the two screw caps are threadedly connected to each other.

[0008] Optionally, an abutment ring is fixed on the sleeve.

[0009] Optionally, a chain connection is fixed between the inner walls of the two sleeves.

[0010] Optionally, the outer casing has a first limiting portion and a second limiting portion disposed on both sides thereon. The first limiting portion is located on the side of the outer casing that is close to each other. The two winding rollers are rotatably connected to the first limiting portion and the second limiting portion respectively. The sleeve is fixed inside the first limiting portion.

[0011] Optionally, a fixing part is rotatably connected to the outer shell, a retaining strip is provided on the side of the outer shell away from the fixing part, and a retaining groove is provided on the other outer shell to cooperate with the retaining strip.

[0012] Optionally, the two red draperys are provided with extensions on their sides that are close to each other, and the two extensions are detachably connected together.

[0013] Optionally, a hanging part is provided on the side of the red cloth curtain away from the outer shell, and both the hanging part and the fixing part are made of magnetic material.

[0014] Optionally, gears are fixedly connected to the ends of the two winding rollers that are far apart from each other, and the two gears mesh with each other when the clip is engaged in the slot.

[0015] Optionally, the winding roller has a plurality of grooves on the side near the second limiting part, and a limiting ball is provided in the groove. The second limiting part has a ball groove for use with the limiting ball, and the limiting ball and the inner wall of the groove are connected by a spring.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention achieves distance adjustment between two outer shells by driving two sleeves to change their relative positions, allowing the red cloth curtain wound by the upper winding roller to switch widths according to different usage scenarios, thus adapting it to different substation protection screens.

[0018] The outer shell of this utility model uses a locking strip and a locking groove to allow the two outer shells to be folded and locked together for easy storage. Furthermore, when the two outer shells are folded and locked together, the two gears mesh with each other. At this time, turning one gear will drive the other gear to rotate, thereby driving the winding roller to wind the red cloth curtain for easy folding.

[0019] This invention achieves mutual fixation between the winding roller and the second limiting part by locking the limiting ball into the ball groove, ensuring that the red cloth will not stretch or shorten due to the rotation of the winding roller during use, thus ensuring the stability of use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] As mentioned earlier, traditional red cloth curtains are typically rolled up by a roller shutter box when not in use, and stretched to a predetermined length for coverage when needed. However, the drawback of this traditional technology is that it can only adjust the height or length vertically, while the horizontal adjustment is limited by the length of the roller shutter box. This results in red cloth curtains being redundant for small displays and unable to completely cover large displays. To address this, this invention provides a winding device for red cloth curtains used in substation protection panels, thereby specifically solving the problems in the existing technology. This invention solves the problem in the following way.

[0031] Example 1:

[0032] Please refer to the instruction manual appendix. Figure 1 and Figure 2 As shown in the figure, this utility model provides a substation protection screen roller shutter-type red cloth curtain device. The device includes at least an outer shell 2, a winding roller 3, a red cloth curtain 1, and an adjustment component 4. Two outer shells 2 are provided, and the two outer shells 2 are symmetrically arranged. Each outer shell 2 includes its main body, and a first limiting part 24 and a second limiting part 25 disposed on both sides of the main body. The first limiting part 24 is located on the side of the outer shell 2 that is close to each other. The first limiting part 24, the second limiting part 25, and the main body together form an open-topped outer shell 2 structure.

[0033] As attached Figure 1 and Figure 2 As shown, in this embodiment, the winding roller 3 is disposed inside the outer shell 2. The two winding rollers 3 are rotatably connected to the first limiting part 24 and the second limiting part 25, respectively, so that they can rotate relative to the outer shell 2. The red cloth drape 1 is wound on the winding roller 3, and there is a certain gap between the winding roller 3 and the body of the outer shell 2. This gap is used to roll the red cloth drape 1 inside the outer shell 2. Rotating the winding roller 3 can drive the red cloth drape 1 to be rolled up or unrolled.

[0034] As attached Figure 1 and Figure 2 As shown, in this embodiment, an adjustment assembly 4 is provided on the side of the two outer shells 2 that are close to each other. The adjustment assembly 4 includes a sleeve 41 fixed within the first limiting part 24. The openings of the two sleeves 41 face the same direction, and the two sleeves 41 have different diameters. The inner diameter of one sleeve 41 is equal to or greater than the outer diameter of the other sleeve 41, which allows the sleeve 41 with the smaller diameter to be nested inside the sleeve 41 with the larger diameter. By adjusting the nesting degree of the two sleeves 41, the distance between the two outer shells 2 can be changed to meet the coverage requirements of a wider substation protection panel.

[0035] like Figure 3As shown, in order to ensure that the positions of the two sleeves 41 can be fixed to each other after adjustment, in this embodiment, threads are provided on the outer wall surface of the side of the two sleeves 41 that are close to each other. A screw cap 43 is threadedly connected to the threads. The screw cap 43 has a different cap diameter depending on the cylinder diameter of the different sleeves 41. The outer cap surface of the screw cap 43 with the smaller cap diameter is also provided with threads, and is threadedly connected to the screw cap 43 with the larger cap diameter through these threads. At the same time, an abutment ring 42 is fixedly connected at the junction of the threaded and unthreaded parts of the sleeves 41. When the screw cap 43 is screwed to abut against the abutment ring 42, the screw cap 43 moves to its maximum position.

[0036] As attached Figure 1 As shown, in this embodiment, the two red cloth curtains 1 are provided with extensions 11 on their sides that are close to each other, and the two extensions 11 are detachably connected together (e.g., by adhesive, Velcro, snap, or zipper). When in use, the two extensions 11 are connected together, and when not in use, the body of the red cloth curtain 1 can be folded and then wound onto the winding roller 3.

[0037] Therefore, in the specific implementation of this embodiment, the smaller diameter sleeve 41 must first be nested inside the larger diameter sleeve 41 and adjusted to the specified length. Then, the smaller diameter cap 43 is screwed on until it abuts against the end face of the larger diameter sleeve 41. Finally, the larger diameter cap 43 is screwed on again until it contacts and is threaded together with the smaller diameter cap 43. Screwing continues until the inner cover surface of the larger diameter cap 43 abuts against the cover end face of the smaller diameter cap 43. At this point, the operation of the adjustment component 4 is completed, and the two outer shells 2 are adjusted to the preset distance.

[0038] Then, the outer casing 2 is fixed to the outside of the substation protection screen, and the red cloth curtain 1 is pulled to extend it to the specified length. Then, the extension part 11 is opened from the main body of the red cloth curtain 1 and connected together. This will cover the substation protection screen, thereby reminding the staff to avoid misoperation.

[0039] Example 2:

[0040] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 4 As shown, a fixing part 21 is rotatably connected to the outer shell 2. In this second embodiment, a preferred embodiment is that the fixing part 21 has several screw holes, which correspond to the screw holes on the substation protection panel housing. In use, screwing in screws of the corresponding specifications can complete the fixing of the outer shell 2 to the substation protection panel.

[0041] In this second embodiment, another preferred implementation is as follows: the fixing part 21 is made of a material with magnetic adsorption capabilities. In use, the fixing part 21 can be placed parallel to the outer casing 2 and adsorbed onto the metal substation protection screen for fixation. Alternatively, the fixing part 21 can be manually rotated to make it perpendicular to the outer casing 2. In this case, it can be erected and adsorbed onto the substation protection screen for fixation. A hanging part 5 is provided on the side of the red cloth drape 1 away from the outer casing 2. The hanging part 5 is also made of a magnetic adsorption material. When the red cloth drape 1 is suspended in use, the hanging part 5 adsorbs onto the outer casing 2 to ensure the stability of the red cloth drape 1. When the red cloth drape 1 is rolled into the winding roller 3, the hanging part 5 and the fixing part 21 can be magnetically attracted to each other for storage.

[0042] Example 3:

[0043] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 2 , Figure 5 As shown, in this third embodiment, the inner walls of the two sleeves 41 are connected by a chain 44. The length of the chain 44 when straightened is greater than the sum of the lengths of the two sleeves 41. The length of the chain 44 should be sufficient to allow the two sleeves 41 to be folded after the nesting is removed, so that the two sleeves 41 do not separate from each other and can still be connected together by the chain 44.

[0044] A retaining strip 23 is provided on the side of the outer shell 2 away from the fixing part 21, and a slot 22 for cooperating with the retaining strip 23 is provided on the other outer shell 2. When the red cloth drape 1 is not in use, it is rolled up onto the winding roller 3, and then the nested connection between the two sleeves 41 is released. At this time, the two outer shells 2 are still connected together under the action of the chain 44. Then, the two outer shells 2 are folded in half so that the retaining strip 23 is engaged into the slot 22, thereby fixing the two outer shells 2 for easy storage.

[0045] Meanwhile, gears 6 are fixedly connected to the ends of the two winding rollers 3 that are far apart from each other. When the locking strip 23 is engaged in the locking groove 22, the two gears 6 mesh with each other. At this time, turning one of the gears 6 causes the winding roller 3 connected to that gear 6 to rotate, thereby rolling up or lowering the red cloth curtain 1 (at this time, the extension 11 on the red cloth curtain 1 needs to be separated). The winding roller 3 on the other side also begins to rotate under the action of the other gear 6, rolling up or lowering the red cloth curtain 1 on that side.

[0046] Example 4:

[0047] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides Embodiment Four. For example... Figure 6As shown in this fourth embodiment, the winding roller 3 has several grooves 31 on its side near the second limiting part 25. A limiting ball 32 is provided within each groove 31. The second limiting part 25 has a ball groove 251 that cooperates with the limiting ball 32. The limiting ball 32 and the inner wall of the groove 31 are connected by a spring 33. When the winding roller 3 and the second limiting part 25 are relatively stationary, the limiting ball 32 is engaged in the ball groove 251 and the groove 31 (it should be noted that when the limiting ball 32 is engaged in the ball groove 251, the center of the limiting ball 32 should be located within the groove 31). When the winding roller 3 is rotated, the limiting ball 32 and the ball groove 251 undergo relative displacement. The ball groove 251 exerts a force on the limiting ball 32, causing the limiting ball 32 to retract into the groove 31. Until it encounters the next ball groove 251, the limiting ball 32 is ejected again under the action of the spring 33 and engaged inside the ball groove 251. It should also be noted that the weight of the red cloth drape 1 itself and the force exerted by the suspension part 5 on the rotation of the winding roller 3 should be less than the force required to drive the limiting ball 32 out of the ball groove 251 and into the groove 31. This ensures that when no force is applied to the winding roller 3, the locking of the ball groove 251 onto the limiting ball 32 prevents the red cloth drape 1 from continuously elongating under the influence of the suspension part 5. This allows the red cloth drape 1 to remain in its desired position.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
