Description

Technical Field

[0001] The utility model relates to the technical field of lightning arrester protection, in particular to a knob-type lightning arrester protective cover. Background Art

[0002] In the existing lightning arrester protection, the protective cover body can usually only provide insulation protection for some specific types of lightning arresters. In the actual protection process, it is impossible to provide insulation protection for various types of lightning arresters.

When the porcelain bottle enters the protection area, the disassembled two sides of the protective cover are reset to form the protective cover body. The existing protective cover body not only makes the operator waste time and effort when performing insulation protection work, but also easily causes damage to the protective cover body under improper operation. At the same time, it does not have the adaptability protection function for a variety of different types of lightning arresters. Utility Model Content

[0028] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below, but is not limited thereto.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0031] It should also be understood that the term “and / or” used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] The following is a detailed description of the implementation details of the technical solution of the embodiment of the present utility model:

[0033] First, it should be noted that, in the process of diffusion, a certain gap will appear between the blades 211 and the blades 211 in the knob type lightning arrester protective cover of the present invention. Then, the thickness of each blade 211 in the present invention can be set. The thickness range of the blade 211 is between 10 mm and 50 mm. The thickness of the blade 211 is appropriately increased. Then, the outside of the protective cover body 2 is farther from the inside of the protective cover body 2. Even if there is a larger conductor (animal, human body, or conductor in artificial movement), it will not be so easy to contact the internal lightning arrester and cause a conductive problem. The smaller the gap between the blades 211, the better the insulation protection effect of the protective cover body 2 of the present invention. Therefore, when the lightning arrester is insulated, the protective space of the anti-slip cover can be selectively reduced as much as possible, that is, the knob block 11 is rotated in the second direction as much as possible to achieve the maximum protection effect. Of course, it should be noted that different application scenarios require different targeted protection options. In some special application scenarios (for example, the wires of the lightning arrester are larger and more numerous, requiring more wiring space), the space utilization of the protective cover body 2 can also be maximized, that is, the knob block 11 is rotated in the first direction so that the blades 211 can spread outward as much as possible in order to maximize the use of the protection space. It should be noted that the wires of the lightning arrester have an insulating effect. What the utility model wants to protect is the conductive risk generated by the lightning arrester body, so the wiring of the lightning arrester will not generate a conductive risk.

[0034] Therefore, according to the problems raised in the above background technology, according to one aspect of the present invention, a knob-type lightning arrester protective cover is provided, including a knob device 1 and a protective cover body 2; the knob device 1 includes a knob block 11 and a plurality of sliding grooves 12, the protective cover body 2 includes a plurality of dispersible blade devices 21, the dispersible blade device 21 includes a blade 211 and a sliding block 212, the sliding block 212 is arranged at the top of the blade 211 and is arranged in the sliding groove 12; the knob block 11 is connected to each of the blades 211; wherein, when the knob block 11 rotates in a first direction, the sliding block 212 slides outward along the guide of the sliding groove 12, driving the blade 211 to spread along the sliding trajectory of the sliding block 212; when the knob block 11 rotates in a second direction, the sliding block 212 slides inward along the guide of the sliding groove 12, driving the blade 211 to shrink along the sliding trajectory of the sliding block 212.

[0035] Specifically, if Figure 1-Figure 2 As shown, Figure 1 This is a schematic diagram of the knob 11 rotating in the first direction to cause the blades 211 to spread. Figure 2 This diagram illustrates the blades 211 retracting as the knob 11 rotates in the second direction. The first direction can be specifically counterclockwise, and the second direction can be specifically clockwise. The sliding path of the slider 212 is formed by the guidance of the sliding trough 12, and the slider 212 can follow this guidance to form a sliding path within the sliding trough 12.

[0036] The protective cover body 2 is composed of a plurality of dispersible blade devices 21, that is, a plurality of blades 211 and a plurality of sliding blocks 212, which are connected to each blade 211 through a knob block 11. When the knob block 11 rotates in a first direction, the sliding groove body 12 also moves, and then the position of the sliding block 212 in the sliding groove body 12 changes relatively, which is equivalent to the sliding block 212 sliding in the sliding groove body 12, so that the blades 211 spread outward as the sliding block 212 slides, thereby increasing the protection space of the protective cover body 2.

[0037] Similarly, when the knob block 11 rotates in the second direction, the sliding groove body 12 will also move, and the position of the sliding block 212 in the sliding groove body 12 will change relatively, which is equivalent to the sliding block 212 sliding in the sliding groove body 12, causing the blade 211 to shrink inward as the sliding block 212 slides, so as to reduce the protective space of the protective cover body 2.

[0038] In one embodiment of the present invention, a plurality of the sliding slots 12 are evenly distributed in the knob block 11 , and each of the sliding slots 12 is a slot with an arc guide.

[0039] Specifically, the plurality of sliding grooves 12 are evenly distributed in the knob block 11, so that when the knob block 11 rotates to drive the sliding groove 12 to move, each sliding block 212 in the sliding groove 12 can maintain consistency of movement due to the uniform distribution, so that the blades 211 can spread more smoothly, because each of the sliding grooves 12 is a groove with an arc guide, and each arc guide has an arc of the same amplitude.

[0040] In one embodiment of the present invention, when the sliding block 212 is located at the inner top end of the sliding trough body 12, the blade 211 is in an extreme contraction state, and when the sliding block 212 is located at the outer top end of the sliding trough body 12, the blade 211 is in an extreme expansion state; wherein, the inner top end of the sliding trough body 12 is the position of the sliding trough body 12 closest to the center of the knob block 11, and the outer top end of the sliding trough body 12 is the position of the sliding trough body 12 farthest from the center of the knob block 11.

[0041] Specifically, Figure 3 As shown, the inner top A of the sliding groove body 12 is the position of the sliding groove body 12 closest to the center of the knob block 11. The knob block 11 can be regarded as a circle with the center of the knob block 11 as the center of the circle. The outer top B of the sliding groove body 12 is the position of the sliding groove body 12 farthest from the center of the knob block 11.

[0042] In one embodiment of the present invention, when the sliding block 212 slides from the inner top to the outer top, each of the blades 211 gradually spreads outward with the knob block 11 as the center. When the sliding block 212 slides from the outer top to the inner top, each of the blades 211 gradually shrinks inward with the knob block 11 as the center.

[0043] Specifically, in the process of the sliding block 212 sliding from the inner top to the outer top, each of the blades 211 gradually spreads outward with the knob block 11 as the center, that is, when the sliding block 212 gradually moves away from the center of the knob block 11, the blades 211 are also driven to gradually spread outward; and in the process of the sliding block 212 sliding from the outer top to the inner top, each of the blades 211 gradually shrinks inward with the knob block 11 as the center, that is, when the sliding block 212 gradually approaches the center of the knob block 11, the blades 211 are also driven to gradually shrink inward.

[0044] In one embodiment of the present invention, the blade 211 includes an upper top 2111, a middle part 2112 and a lower side part 2113; the sliding block 212 is arranged on the upper top 2111, and the upper top 2111 is respectively connected to the middle part 2112 and the knob block 11; the lower side part 2113 can be bent and connected to the middle part 2112.

[0045] Specifically, the sliding block 212 is disposed on the upper surface of the upper portion 2111, and the upper portion 2111 contacts the knob block 11, while the middle portion 2112 is disposed below the upper portion 2111, and the lower portion 2113 is bendably connected to the middle portion 2112. The lower portion 2113 can be bent at any time, and can be bent inward to further protect the arrester, or bent outward to increase some protective space.

[0046] In one embodiment of the present invention, the knob block 11 includes an upper top block 111 and a lower bottom block 112, and a plurality of sliding grooves 12 are opened in the upper top block 111, and are slidingly connected to each of the sliding blocks 212; the lower bottom block 112 is connected to the lower surface of the upper top 2111, and the sliding block 212 is arranged on the upper surface of the upper top 2111.

[0047] Specifically, the knob block 11 includes an upper top block 111 and a lower bottom block 112, and a plurality of sliding slots 12 are opened in the upper top block 111, wherein each adjacent position of each sliding slot 12 in the upper top block 111 is provided with a corresponding card slot, and the sliding block 212 extends into the sliding slot 12 through the card slot.

[0048] In one embodiment of the present invention, the upper top 2111 of the blade 211 is further provided with a wiring groove 2114 . The wiring groove 2114 is provided between the upper top block 111 and the lower bottom block 112 and communicates with the interior of the upper top block 111 .

[0049] The upper top 2111 of the blade 211 is provided with a wiring groove 2114 for routing the wires. The wiring groove 2114 is arranged between the upper top block 111 and the lower bottom block 112 to communicate with the interior of the upper top block 111, that is, it can be electrically connected to the detection device 13 placed on the upper top block 111.

[0050] In an embodiment of the present invention, the knob device 1 further includes a detection device 13 , and the detection device 13 is provided on the knob block 11 .

[0051] Specifically, the detection device 13 can be a sensor device that can be used to detect parameters such as temperature and smoke concentration. By setting the detection device 13 on the top of the protective cover body 2, the operating parameters of the lightning arrester during operation can be detected in real time, and an alarm can be issued in time when a dangerous situation occurs.

[0052] In one embodiment of the present invention, the knob-type lightning arrester protective cover further includes a wiring cover 3 , which includes a first cover 31 and a second cover 32 . The first cover 31 and the second cover 32 are respectively arranged on the sides of two adjacent blades 211 .

[0053] Specifically, the wiring cover 3 is mainly used for wiring the lightning arrester. It should be noted that the wiring groove 2114 is used for wiring the detection device 13, while the wiring cover 3 can be used for wiring all electrical wires. By respectively providing the first cover 31 and the second cover 32 on the sides of two adjacent blades 211, the wires of the lightning arrester can be guided out of the wiring cover 3 formed by the first cover 31 and the second cover 32.

[0054] In summary, the present invention has a sliding block 212 disposed on the top of the blade 211 and arranged to slide in the sliding groove 12, and the knob block 11 is connected to each of the blades 211. Then, when the knob block 11 is rotated in the first direction, the sliding block 212 slides outward along the guide of the sliding groove 12, driving the blades 211 to spread along the sliding trajectory of the sliding block 212. Therefore, the diffusibility of the blades 211 can increase the protective space of the entire protective cover body 2, so that the entire knob-type lightning arrester protective cover can be adaptively protected for lightning arresters of different specifications and sizes.

[0055] Furthermore, the utility model can also place the lightning arrester into the protective cover body 2 in the form of a diffuser blade 211, and then adaptively retract the blade 211 according to the position of the lightning arrester, which can avoid the existing method of placing the lightning arrester in a detachable manner, effectively saving time and effort and not easily causing damage to the protective cover body 2.

[0056] Furthermore, if the size of the lightning arrester is small, the knob block 11 can be rotated in the second direction, causing the sliding block 212 to slide inward along the guide of the sliding groove body 12, driving the blades 211 to retract along the sliding trajectory of the sliding block 212. In this way, the gaps between the blades 211 are smaller, and the insulation protection effect is better. Therefore, the utility model has high adaptability and is convenient for operators to perform lightning arrester protection.
