Description

Technical Field

[0001] The invention relates to the technical field of lightning protection, in particular to a lightning protection cover. Background Art

[0002] The lightning protection cover is used to guide lightning to itself, and discharge the lightning current into the earth through the down conductor connected to it through the grounding device, so as to protect the protected object from lightning strikes. It can be used for outdoor electrical equipment, such as charging piles. The charging piles need to have good grounding to ensure the safety of personnel against electric shock during charging operations. At the same time, it also ensures that the passage of lightning current into the ground is unobstructed when lightning strikes, so as to prevent personnel from being struck by lightning. The lightning protection design and installation of the charging piles shall comply with the lightning protection design requirements of the third type of lightning protection buildings, and a lightning risk assessment shall be carried out. According to the assessment results, corresponding protective measures shall be taken. Since the existing cover is manufactured in an integrated manner and ensures that it can cover the entire equipment, it indirectly leads to the inconvenience of adjusting the size of the cover, and it is not convenient to adapt to the external protected equipment of different heights and shapes. In addition, there is a possibility of short circuit fire in outdoor electrical equipment, and the cover is not convenient to adjust, resulting in the coverage of the fire extinguishing agent not being concentrated, which increases the waste of the fire extinguishing agent, and makes the fire extinguishing agent unable to act more effectively on the fire source, reducing the fire extinguishing effect.

[0003] The object of the present invention is to provide a lightning protection cover to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A lightning protection device comprises a mounting bracket, wherein a mounting plate is slidably connected to the outer surface of the mounting bracket;

[0006] The lower surface of the mounting plate is movably connected with an adjustment module, and the adjustment module includes:

[0007] The mounting cover is movably connected to the bottom of the mounting plate, the inner top surface of the mounting cover is fixedly connected with an electric push rod, and the output end of the electric push rod is fixedly connected to the mounting plate;

[0008] The limiting rails are fixedly connected to the lower surface of the mounting cover near the four corners;

[0009] The hanging rod is fixedly connected to the inner surface of the mounting cover;

[0010] The hanging fire extinguisher is hung on the outer surface of the hanging rod;

[0011] The side plate is fixedly connected to the lower surface of the mounting cover;

[0012] The rear surface of the mounting cover is rotatably connected to a first baffle plate, the front surface of the mounting cover is rotatably connected to a second baffle plate, and the outer surface of the side plate is detachably connected to a limiting seat.

[0013] Furthermore, two through grooves are provided on the upper surface of the mounting plate, a clamping block is slidably connected inside the through groove, a connecting plate is detachably connected to the lower surface of the clamping block, and a double-headed screw is threadedly connected to the outer surface of the connecting plate.

[0014] Furthermore, the clamping block matches the mounting bracket, and the mounting plate is slidably connected with the clamping block and the mounting bracket.

[0015] Furthermore, a rack is fixedly connected to the lower surface of the mounting plate, and the rack is slidably connected to the limiting rail.

[0016] Furthermore, both ends of the first baffle plate are fixedly connected with a first gear, both ends of the second baffle plate are fixedly connected with a second gear, and the rack is meshedly connected with the first gear and the second gear.

[0017] Furthermore, a door body is hingedly connected to the front surface of the second baffle plate, and a handle is fixedly connected to the outer surface of the door body.

[0018] Furthermore, a cross bar is embedded and connected to the outer surface of the limit seat, and a fire curtain is embedded and connected to the outer surface of the cross bar.

[0019] Furthermore, a tie is fixedly connected to the outer surface of the fire curtain near the lower end, the lower end of the fire curtain is connected to the first baffle and the second baffle through the tie, and the fire curtain is fan-shaped.

[0020] Furthermore, a lightning rod is detachably connected to the upper surface of the installation cover.

[0021] Furthermore, the outer surface of the lightning rod is electrically connected with a connecting wire, and the connecting wire is electrically connected to the mounting bracket.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the No. 1 gear and the No. 2 gear rotate, the No. 1 baffle and the No. 2 baffle can be flipped outward, so that the No. 1 baffle and the No. 2 baffle are in the shape of an "eight", so that the size of the cover can be adjusted, and the design of the eight-shaped shape helps to form a uniform and stable electric field environment around the lightning protection cover, which is very important for achieving the effect of lightning protection. In addition, the adjustable size enables it to adapt to external protected equipment of different heights and shapes.

[0024] 2. The lower end of the fire curtain is connected to the No. 1 baffle and the No. 2 baffle through a tie. When the protected equipment catches fire, the electric push rod is started, and the output end of the electric push rod grows, so that the distance between the mounting plate and the mounting cover increases, and the No. 1 baffle and the No. 2 baffle move inward, and drive the fire curtain to fold inward, so that the relatively closed space composed of the mounting cover, the No. 1 baffle, the fire curtain and the No. 2 baffle is reduced. At this time, the suspended fire extinguisher starts to extinguish the fire. Due to the reduction of space, the coverage of the fire extinguishing agent is more concentrated, which reduces the waste of the fire extinguishing agent, enables the fire extinguishing agent to act more effectively on the fire source, and improves the fire extinguishing effect.

[0025] 3. Hanging fire extinguishers are usually equipped with temperature-sensitive glass balls. When the ambient temperature rises, the liquid in the glass ball automatically expands due to heat and breaks, the sealing piece automatically falls off, and the dry powder agent in the fire extinguishing device is sprayed out from the nozzle under the action of nitrogen to extinguish the fire. This design enables the hanging fire extinguisher to respond quickly to fire in a small space. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] 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 described embodiments are only 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 creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-9 In an embodiment of the present invention, a lightning protection cover includes a mounting bracket 1, and a mounting plate 2 is slidably connected to the outer surface of the mounting bracket 1;

[0038] The lower surface of the mounting plate 2 is movably connected with an adjustment module 3, and the adjustment module 3 includes:

[0039] The mounting cover 301 is movably connected to the bottom of the mounting plate 2, and the inner top surface of the mounting cover 301 is fixedly connected with the electric push rod 205, and the output end of the electric push rod 205 is fixedly connected to the mounting plate 2;

[0040] The limiting rails 302 are fixedly connected to the lower surface of the mounting cover 301 near the four corners;

[0041] The hanging rod 303 is fixedly connected to the inner surface of the mounting cover 301;

[0042] The hanging fire extinguisher 304 is hung on the outer surface of the hanging rod 303;

[0043] The side plate 305 is fixedly connected to the lower surface of the mounting cover 301;

[0044] The rear surface of the mounting cover 301 is rotatably connected to a first baffle plate 4 , the front surface of the mounting cover 301 is rotatably connected to a second baffle plate 5 , and the outer surface of the side plate 305 is detachably connected to a limiting seat 6 .

[0045] Specifically, when in use, a hole is opened on the upper surface of the mounting bracket 1, which can be fixed to the ground with an anchor bolt, and the end of the anchor bolt is connected to the ground wire through a connecting wire to complete the grounding of the mounting bracket 1. The double-headed screw rod 204 is rotated, and the two connecting plates 203 move inward under the push of the thread, driving the clamping block 202 to slide inward along the through groove 201, and the double-headed screw rod 204 is rotated in the opposite direction. Under the push of the thread, the two connecting plates 203 move outward, driving the clamping block 202 to slide outward along the through groove 201, which can support the disassembly of a single mounting plate 2, and is convenient for replacing or repairing the cover body. When installing, the electric push rod 205 is started, and the output end of the electric push rod 205 is contracted, so that the distance between the mounting plate 2 and the mounting cover 301 is shortened, and the rack 206 moves along the limit rail 302. Driven by the rack 206, the first gear 401 and the second gear 501 rotate, so that the first baffle 4 and the second baffle 5 can be turned outward, so that the first baffle 4 and the second baffle 5 are in an "eight" shape, so that the size of the cover body can be adjusted, and the eight-shaped design helps to form a uniform and stable electric field environment around the lightning protection cover, which is very important for achieving the effect of lightning protection. In addition, the adjustable size enables it to be suitable for According to the external protected equipment of different heights and shapes, the lower end of the fire curtain 602 is connected to the first baffle 4 and the second baffle 5 through the tie 7. When the protected equipment catches fire, the electric push rod 205 is started, and the output end of the electric push rod 205 grows, so that the distance between the mounting plate 2 and the mounting cover 301 increases, and the first baffle 4 and the second baffle 5 move inward, and drive the fire curtain 602 to fold inward, so that the relatively closed space formed by the mounting cover 301, the first baffle 4, the fire curtain 602 and the second baffle 5 is reduced. At this time, the hanging fire extinguisher 304 starts to extinguish the fire. As the space is reduced, the coverage of the fire extinguishing agent is more concentrated, which reduces the waste of the fire extinguishing agent, enables the fire extinguishing agent to act more effectively on the fire source, and improves the fire extinguishing effect. The hanging fire extinguisher 304 is usually equipped with a temperature-sensitive glass ball. When the ambient temperature rises, the liquid in the glass ball automatically expands and breaks due to heat expansion, the sealing sheet automatically falls, and the dry powder agent in the fire extinguishing device is sprayed from the nozzle under the action of nitrogen to extinguish the fire. This design enables the hanging fire extinguisher 304 to respond quickly to the fire in a narrow space environment, and when the first baffle 4 and the second baffle 5 are expanded to the maximum position, such as Figure 8 As shown, the cover body is in the shape of an "I", which saves space occupied by the cover body and is convenient for the transportation of the device. When struck by lightning, the lightning rod 8 cooperates with the connecting wire 9 to transmit the lightning to the clamp block 202, and then the clamp block 202 cooperates with the mounting bracket 1 and the anchor bolt to transmit electricity to the ground to complete the protection operation.

[0048] In this embodiment, a hole is opened on the upper surface of the mounting bracket 1, which can be fixed to the ground with an anchor bolt, and the end of the anchor bolt is connected to the ground wire through a connecting wire to complete the grounding of the mounting bracket 1. The double-headed screw 204 is rotated, and the two connecting plates 203 move inward under the push of the thread, driving the clamping block 202 to slide inward along the through groove 201.

[0049] like Figure 1-4 As shown, the clamp block 202 matches the mounting bracket 1 , and the mounting plate 2 is slidably connected to the mounting bracket 1 through the clamp block 202 .

[0050] During specific implementation, the inward sliding clamping block 202 clamps the mounting bracket 1. Based on this, multiple mounting plates 2 can be installed on the mounting bracket 1, so that the cover body is suitable for multiple devices, such as charging piles installed in the open air, and the double-headed screw 204 is rotated in the opposite direction. Under the push of the thread, the two connecting plates 203 move outward, driving the clamping block 202 to slide outward along the through groove 201, which can support the disassembly of a single mounting plate 2, making it easy to replace or repair the cover body.

[0051] Embodiment 2

[0054] During specific implementation, the electric push rod 205 is started during installation, and the output end of the electric push rod 205 contracts, so that the distance between the mounting plate 2 and the mounting cover 301 is shortened, and the rack 206 moves along the limit rail 302. Driven by the rack 206, the No. 1 gear 401 and the No. 2 gear 501 rotate, so that the No. 1 baffle 4 and the No. 2 baffle 5 can be flipped outward, so that the No. 1 baffle 4 and the No. 2 baffle 5 are in an "eight" shape, so that the size of the cover body can be adjusted, and the eight-shaped design helps to form a uniform and stable electric field environment around the lightning protection cover, which is very important for achieving the effect of lightning protection. In addition, the adjustable size enables it to adapt to external protected equipment of different heights and shapes.

[0055] like Figure 5-9 As shown, the front surface of the second baffle 5 is hinged with a door body 502, the outer surface of the door body 502 is fixedly connected with a handle, the outer surface of the limit seat 6 is embedded with a cross bar 601, and the outer surface of the cross bar 601 is nested with a fire curtain 602.

[0056] During specific implementation, when the protected equipment needs to be used, the door body 502 is opened to connect the external equipment with the equipment in the cover body. The fire curtain 602 is flexible and can be deployed. It is installed through the cross bar 601 and the limit seat 6. The cover body presents an "I" shape, which saves the space occupied by the cover body and is conducive to the transportation of the device.

[0057] like Figure 5-9 As shown, the outer surface of the fire curtain 602 is fixedly connected with a tie 7 near the lower end, and the lower end of the fire curtain 602 is connected to the first baffle 4 and the second baffle 5 through the tie 7. The fire curtain 602 is fan-shaped, and the upper surface of the mounting cover 301 is detachably connected with a lightning rod 8. The outer surface of the lightning rod 8 is electrically connected with a connecting wire 9, and the connecting wire 9 is electrically connected to the mounting bracket 1.

[0058] In specific implementation, the lower end of the fire curtain 602 is connected to the No. 1 baffle 4 and the No. 2 baffle 5 through the tie 7. When the protected equipment catches fire, the electric push rod 205 is started, and the output end of the electric push rod 205 grows, so that the distance between the mounting plate 2 and the mounting cover 301 increases, and the No. 1 baffle 4 and the No. 2 baffle 5 move inward, and drive the fire curtain 602 to fold inward, so that the relatively closed space formed by the mounting cover 301, the No. 1 baffle 4, the fire curtain 602 and the No. 2 baffle 5 is reduced. At this time, the hanging fire extinguisher 304 is opened. Fire extinguishing work begins. As the space is reduced, the coverage of the fire extinguishing agent is more concentrated, which reduces the waste of the fire extinguishing agent, enables the fire extinguishing agent to act more effectively on the fire source, and improves the fire extinguishing effect. The hanging fire extinguisher 304 is usually equipped with a temperature-sensitive glass ball. When the ambient temperature rises, the liquid in the glass ball automatically expands and breaks due to heat expansion, and the sealing sheet automatically falls off. The dry powder agent in the fire extinguishing device is sprayed from the nozzle under the action of nitrogen to extinguish the fire. This design enables the hanging fire extinguisher 304 to respond quickly to fire in a narrow space environment;

[0059] When struck by lightning, the lightning rod 8 cooperates with the connecting wire 9 to transmit the lightning to the clamp block 202, and then the clamp block 202 cooperates with the mounting bracket 1 and the anchor bolt to transmit the electricity to the ground to complete the protection operation.
