Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of protective cover technology, and more specifically, to visual insulating protective covers. Background Technology

[0002] With the rapid development of the power industry, the requirements for the operational safety and reliability of electrical equipment are increasing, and the limitations of traditional insulation protection methods are becoming more and more prominent. In order to better ensure the safe and stable operation of electrical equipment and reduce operation and maintenance costs, a visual insulation protective cover has emerged. This protective cover combines advanced material technology and monitoring technology and is made of transparent or semi-transparent insulating materials, allowing operation and maintenance personnel to directly observe the operating status of internal electrical components.

[0003] According to the published insulating protective cover for the disconnecting switch (publication number: CN207966832U), it includes a first main shell, a second main shell fixedly installed on the bottom outer surface of the first main shell, holes fixedly installed on the inner surfaces of the first and second main shells, a connecting rod fixedly installed on the outer surface of the holes, fixing nuts fixedly installed at both ends of the outer surface of the connecting rod, a fixing sleeve fixedly installed on one side of the outer surface of the first main shell, a soft pad fixedly installed on the bottom end of the inner wall of the fixing sleeve, a limit sleeve fixedly installed on the bottom outer surface of the first main shell, and an outlet fixedly installed on the bottom inner surface of the limit sleeve.

[0004] In the aforementioned application, when the wiring inside the protective cover malfunctions and needs repair, disassembly is complex, time-consuming, and labor-intensive, which needs improvement. Therefore, we proposed a visual insulating protective cover. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a visual insulating protective cover, which solves the problem in the related art that when the wires inside the protective cover fail and need to be repaired, disassembly is complicated, time-consuming and labor-intensive.

[0006] According to one aspect, at least one embodiment of this disclosure provides a visual insulating protective cover, comprising: a protective cover body, wherein an inlet pipe extends through a side of the protective cover body, and a groove is formed on the surface of the protective cover body, wherein an easy disassembly mechanism is provided on the inner sidewall of the groove;

[0007] The easy-to-disassemble mechanism includes a hollow plate, which is fixedly connected to the inner wall of the groove. A torsion spring rod is rotatably connected to the inner wall of the hollow plate. A sleeve is fixedly connected to the circumferential surface of the torsion spring rod. A protective plate is fixedly connected to the circumferential surface of the sleeve. A connecting plate is fixedly connected to the circumferential surface of the protective plate. A connecting rod is fixedly connected to the bottom of the connecting plate. A contact block is fixedly connected to the end of the connecting rod away from the connecting plate. A hollow block is fixedly connected to the front side of the protective cover body. A limit plate is slidably connected to the inner wall of the hollow block.

[0008] For example, in at least one embodiment of the present disclosure, the visual insulating protective cover further includes: a pressure block fixedly connected to the top of the limiting plate, a connecting spring fixedly connected to the inner side wall of the hollow block, and the end of the connecting spring away from the hollow block fixedly connected to the rear side of the limiting plate; and a handle fixedly connected to the inner side wall of the limiting plate. The handle is designed to facilitate operation by the staff when the protective cover body needs to be disassembled.

[0009] The contact block is located on the movement trajectory of the limiting plate. The side cross-section of the limiting plate is L-shaped. The initial state of the connecting spring is set to a relaxed state. The design of the connecting spring is conducive to driving the limiting plate to reset.

[0010] The pressure block is located on the movement trajectory of the contact block. The side cross section of the pressure block is set as a triangle. The design of the pressure block is advantageous because when the pressure block is squeezed, it drives the limiting plate to move.

[0011] The hollow plate has a concave side section, and the hollow block has a concave side section. The design of the hollow plate helps to make the torsion spring rod more stable during rotation.

[0012] The side cross-section of the groove is set to be arc-shaped, which is beneficial for fitting the shape of the protective plate.

[0013] The protective plate is made of a visible material, and its side cross-section is arc-shaped. The protective plate is in contact with the inner wall of the groove. This design facilitates the observation of the wires by the staff.

[0014] According to another aspect, at least one embodiment of this disclosure also provides a visual insulating protective cover, including a cable management mechanism disposed inside the cover body. The cable management mechanism includes a sliding groove, which is formed on the inner side wall of the cover body. A sliding plate is slidably connected to the inner side wall of the sliding groove. A fixing rod is fixedly connected to the rear side of the sliding plate. A clamping plate is fixedly connected to the circumferential surface of the fixing rod. A return spring is fixedly connected to the front side of the sliding plate, and the end of the return spring away from the sliding plate is fixedly connected to the inner side wall of the sliding groove. The above design is beneficial to prevent messy wires and makes it difficult for workers to distinguish them.

[0015] For example, in at least one embodiment of the present disclosure, the visual insulating protective cover further includes a moisture-proof board fixedly connected to the inner side wall of the protective cover body. The above design is beneficial for absorbing moisture inside the protective cover body.

[0016] The cable management mechanism is set to several groups, and they are symmetrical along the vertical central axis of the top of the moisture-proof board. This design is conducive to clamping the wires more stably.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, the rotational force of the torsion spring rod drives the sleeve, protective plate, connecting plate, connecting rod, contact block, hollow block, limiting plate, connecting spring, handle, and pressure block to cooperate with each other. This enables the handle fixed at the bottom of the limiting plate to be pushed, thereby driving the limiting plate sliding on the bottom of the inner wall of the hollow block to move. At the same time, the connecting spring fixed on the rear side of the limiting plate is in a taut state. When the limiting plate is no longer in contact with the contact block, the torsion spring rod on the inner side wall of the hollow plate rotates. When the wire malfunctions, it is convenient for the staff to open the protective cover, saving time and effort and making the operation simple.

[0019] 2. In this utility model, the sliding force of the sliding plate drives the fixed rod, clamping plate, return spring and other components to work together to pull the two sliding plates sliding on the inner side wall of the groove, thereby driving the two fixed rods fixed on the rear side to move. The movement of the two fixed rods drives the two clamping plates fixed on the circumferential surface to move. At the same time, the movement of the sliding plate keeps the return spring fixed on the front side in a taut state. When the wire enters the protective cover, the wire is clamped, which facilitates the subsequent operation of the staff. Attached Figure Description

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, a visual insulating protective cover in one embodiment of the present disclosure is illustrated, including: a protective cover body 1, an inlet pipe 2 passing through the side of the protective cover body 1, a groove 3 formed on the surface of the protective cover body 1, and a disassembly mechanism 4 provided on the inner side wall of the groove 3.

[0034] The easy-to-disassemble mechanism 4 includes a hollow plate 41, which is fixedly connected to the inner wall of the groove 3. A torsion spring rod 42 is rotatably connected to the inner wall of the hollow plate 41. A sleeve 43 is fixedly connected to the circumferential surface of the torsion spring rod 42. A protective plate 44 is fixedly connected to the circumferential surface of the sleeve 43. A connecting plate 45 is fixedly connected to the circumferential surface of the protective plate 44. A connecting rod 46 is fixedly connected to the bottom of the connecting plate 45. A contact block 47 is fixedly connected to the end of the connecting rod 46 away from the connecting plate 45. A hollow block 48 is fixedly connected to the front side of the protective cover body 1. A limit plate 49 is slidably connected to the inner wall of the hollow block 48.

[0035] In some examples, the following are also included: a pressure block 412 is fixedly connected to the top of the limiting plate 49, a connecting spring 410 is fixedly connected to the inner side wall of the hollow block 48, and the end of the connecting spring 410 away from the hollow block 48 is fixedly connected to the rear side of the limiting plate 49. A handle 411 is fixedly connected to the inner side wall of the limiting plate 49. The design of the handle 411 is to facilitate the operation of the staff when the staff needs to disassemble the protective cover body 1.

[0036] The contact block 47 is located on the movement trajectory of the limiting plate 49. The side section of the limiting plate 49 is set to L-shape. The initial state of the connecting spring 410 is set to a relaxed state. The design of the connecting spring 410 is conducive to driving the limiting plate 49 to reset.

[0037] The pressure block 412 is located on the movement trajectory of the contact block 47. The side cross section of the pressure block 412 is set as a triangle. The design of the pressure block 412 is advantageous because when the pressure block 412 is squeezed, it drives the limiting plate 49 to move.

[0038] The side cross-section of the hollow plate 41 is set to be concave, and the side cross-section of the hollow block 48 is set to be concave. The design of the hollow plate 41 helps to make the torsion spring rod 42 more stable during rotation.

[0039] The side cross-section of the groove 3 is set to be arc-shaped, and the above design is conducive to fitting the shape of the protective plate 44.

[0040] The protective plate 44 is made of a visible material, and its side cross-section is arc-shaped. The protective plate 44 is in contact with the inner wall of the groove 3. The above design facilitates the observation of the wires by the staff.

[0041] For example, such as Figures 1-5 As shown, when the worker needs to repair or inspect the wire, the worker pushes the handle 411 fixed to the bottom of the limiting plate 49, thereby causing the limiting plate 49, which slides on the bottom of the inner wall of the hollow block 48, to move. At the same time, the connecting spring 410 fixed to the rear side of the limiting plate 49 is in a taut state. When the limiting plate 49 is no longer in contact with the contact block 47, the torsion spring rod 42 on the inner wall of the hollow plate 41 rotates, thereby causing the sleeve 43 fixed on the circumferential surface to rotate. The rotation of the sleeve 43 causes the protective plate 44 fixed on the circumferential surface to move upward in an arc. At this time, the protective plate 44 is no longer in contact with the inner wall of the groove 3. The worker repairs or inspects the wire. After the repair is completed, the worker presses the protective plate 44 downward, thereby causing the protective plate to... 44 moves downward in an arc, simultaneously causing the connecting plate 45 fixed on the circumferential surface to move downward in an arc. The movement of the connecting plate 45 causes the connecting rod 46 fixed at the bottom to move, and the movement of the connecting rod 46 causes the contact block 47 fixed at the other end to move downward in an arc. When the contact block 47 moves to a certain position, it presses the pressure block 412 fixed at the top of the limiting plate 49. When the pressure block 412 is pressed, it causes the limiting plate 49 to slide at the bottom of the inner wall of the hollow block 48, and at the same time, it causes the connecting spring 410 to be in a taut state again. When the contact block 47 no longer presses the pressure block 412, the connecting spring 410 returns to its original position according to its own elasticity, and at the same time, it causes the limiting plate 49 to return to its original position, so that the bottom of the limiting plate 49 contacts the top of the contact block 47, thus completing the locking.

[0042] like Figures 1-5As shown, a visual insulating protective cover is provided in another embodiment of this disclosure. It is largely the same as the technical solution of embodiment 1, so only the differences are described. The protective cover body 1 is provided with a cable management mechanism 5. The cable management mechanism 5 includes a slide groove 51. The slide groove 51 is opened on the inner side wall of the protective cover body 1. A sliding plate 53 is slidably connected to the inner side wall of the slide groove 51. A fixing rod 54 is fixedly connected to the rear side of the sliding plate 53. A clamping plate 55 is fixedly connected to the circumferential surface of the fixing rod 54. A return spring 56 is fixedly connected to the front side of the sliding plate 53, and the end of the return spring 56 away from the sliding plate 53 is fixedly connected to the inner side wall of the slide groove 51. The above design is beneficial to prevent the wires from being messy and difficult for workers to distinguish.

[0043] In some examples, a moisture-proof board 52 is fixedly connected to the inner wall of the protective cover body 1, and the above design is conducive to absorbing moisture inside the protective cover body 1.

[0044] The cable management mechanism 5 is set to several groups, and they are symmetrical along the vertical central axis of the top of the moisture-proof board 52. The above design is conducive to clamping the wires more stably.

[0045] For example, such as Figures 1-5 As shown, when the worker delivers the wire through the inlet pipe 2 that runs through the side of the protective cover body 1, the worker pulls the two sliding plates 53 that slide on the inner wall of the slide groove 51, thereby driving the two fixed rods 54 fixed on the rear side to move. The movement of the two fixed rods 54 drives the two clamping plates 55 fixed on the circumferential surface to move. At the same time, the movement of the sliding plate 53 keeps the return spring 56 fixed on the front side in a taut state. When the worker places the wire inside the clamping plate 55, the worker releases the sliding plate 53. At this time, the return spring 56 returns to its original position according to its own elasticity, thereby driving the sliding plate 53 to return to its original position. The return of the sliding plate 53 drives the fixed rods 54 and the clamping plates 55 to return to their original positions, thus completing the wire handling.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
