The following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0041] In the prior art, a lightning protection device primarily consists of a lightning rod and a base. The lightning rod is fixed to the top of the base. The base is installed outdoors in a specific location and is grounded. This makes the outdoor lightning protection device susceptible to external interference, and components such as the lightning rod or the base are easily damaged. Since the lightning rod and the base are fixed, if either is damaged, the entire device must be replaced, resulting in high replacement costs.

[0042] In order to overcome the defects in the prior art, the present application provides a lightning protection device, including a base, a lightning protection assembly, and a fastening assembly; the lightning protection assembly includes a lightning rod and a mounting seat, the mounting seat can be detachably mounted on the base, and the lightning rod is arranged on the mounting seat; the fastening assembly includes at least one pressure plate, one end of the pressure plate acts on the base, and the other end acts on the mounting seat, and the pressure plate connects the mounting seat and the base; the pressure plate is released from the base and the mounting seat, so that the mounting seat can be detached from the base. This application is used to solve the problem of high replacement costs of lightning protection devices.

[0043] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0044] Figure 1 A schematic diagram of a lightning protection device provided in an embodiment of the present application.

[0045] Figure 2 for Figure 1Enlarged view of point A in the middle.

[0046] See also Figure 1 and Figure 2 , the present application provides a lightning protection device, comprising a base 100, a lightning protection assembly 200 and a fastening assembly 300;

[0047] The lightning protection assembly 200 includes a lightning rod 210 and a mounting base 220 . The mounting base 220 can be detachably mounted on the base 100 , and the lightning rod 210 is disposed on the mounting base 220 .

[0048] The fastening assembly 300 includes at least one pressing plate 310 . One end of the pressing plate 310 acts on the base 100 , and the other end acts on the mounting seat 220 . The pressing plate 310 connects the mounting seat 220 and the base 100 .

[0049] The action of the pressing plate 310 on the base 100 and the mounting base 220 is released, so that the mounting base 220 is detached from the base 100 .

[0050] Exemplarily, the number of the pressing plates 310 is one or more, which is not limited here.

[0051] It should be noted that the lightning rod 210 is provided with a mounting seat 220 on a side facing away from the base 100. One end of the pressure plate 310 is connected to the mounting seat 220, and the other end is connected to the base 100; optionally, the pressure plate 310 and the mounting seat 220 and the base 100 can be connected by welding or bonding. When one of the base 100 or the lightning protection assembly 200 is damaged, the pressure plate 310 can be removed from the mounting seat 220 and the base 100 first, and finally the lightning protection assembly 200 can be removed from the base 100, and the damaged part can be replaced, and then the replaced part and the previously usable part can be reinstalled; in this way, when one of the base 100 or the lightning protection assembly 200 is damaged, the damaged part can be replaced by disassembly, without the need for overall replacement, thereby reducing replacement costs.

[0052] In some embodiments, a mounting groove 400 is provided on the base 100 , and the mounting seat 220 is partially inserted into the mounting groove 400 . One end of the pressure plate 310 acts on the top of the base 100 , and the other end acts on the top of the mounting seat 220 .

[0053] Exemplarily, the mounting groove 400 is disposed at the top center of the base 100. In this embodiment, the mounting seat 220 is cylindrical, and thus the mounting groove 400 and the mounting seat 220 are also cylindrical counterbores. The depth of the cylindrical counterbores is less than the height of the mounting seat 220, that is, the top surface of the mounting seat 220 is higher than the top surface of the base 100. Thus, the mounting seat 220 is wrapped around the mounting groove 400, improving the reliability of the mounting seat 220 when installed on the base 100. In addition, the pressure plate 310 is inclined from the base 100 toward the mounting seat 220, forming a triangular structure between the pressure plate 310, the mounting seat 220, and the base 100. The pressure plate 310 provides triangular support for the mounting seat 220, improving the stability of the mounting seat 220 in the mounting groove 400 and indirectly improving the stability of the lightning rod 210 on the mounting seat 220, thereby preventing the lightning rod 210 from swinging.

[0054] See also Figure 2 In some embodiments, a clamping block 311 is provided at one end of the pressure plate 310 close to the mounting seat 220, and a clamping slot 221 adapted to the clamping block 311 is provided on the mounting seat 220. The clamping block 311 is snapped into the clamping slot 221 to achieve the connection between the pressure plate 310 and the mounting seat 220.

[0055] Exemplarily, the slot 221 is set at the top of the mounting base 220, and one end of the pressure plate 310 realizes quick connection between itself and the mounting base 220 by means of the clamping block 311 and the slot 221. On the contrary, the disassembly between the slot 221 and the block 311 is also convenient, which is conducive to removing the mounting base 220 from the base 100. When one of the lightning protection assembly 200 or the base 100 is damaged, the two can be quickly separated and the damaged part can be replaced in a targeted manner.

[0056] In addition, the end of the pressing plate 310 connected to the base 100 can also adopt the same clamping method to achieve the same effect of facilitating installation and disassembly.

[0057] In some embodiments, the fastening assembly 300 further includes at least one limiting screw 320 .

[0058] The limiting screw 320 passes through one end of the pressing plate 310 and is screwed to the mounting base 220 .

[0059] Exemplarily, the number of the limiting screws 320 may be one or more, which is not limited here; the limiting screws 320 are T-shaped, so that the head of the limiting screws 320 forms a limit on the top of the pressure plate 310.

[0060] See also Figure 2 and Figure 3It should be noted that the limiting screw 320 secures one end of the pressing plate 310 to the mounting base 220, thereby enhancing the stability of the connection between the pressing plate 310 and the mounting base 220. Furthermore, the limiting screw 320 is threadedly connected, facilitating removal and installation. Specifically, the mounting base 220 is provided with a plurality of threaded holes 500, and each pressing plate 310 is provided with two limiting screws 320. The limiting screws 320 pass through the pressing plate 310 and are then threadedly connected to the threaded holes 500. Preferably, at least two limiting screws 320 are provided on one end of the pressing plate 310 for securing the pressing plate 310.

[0061] In addition, the threaded hole 500 on the mounting base 220 for threading the limiting screw 320 is set in the clamping groove 221. In this way, the clamping groove 221 and the threaded hole 500 are combined in the same position, thereby concentrating the clamping and threading of the pressure plate 310 and the mounting base 220 at the same position, thereby enhancing the reliability of the connection between the pressure plate 310 and the mounting base 220. Therefore, it can be seen that the limiting screw 320 passes through the pressure plate 310 and the clamping block 311 at the same time, and finally is threaded into the threaded hole 500. Furthermore, the limiting screw 320 and the pressure plate 310 can also be threaded together, thereby preventing the pressure plate 310 from jumping in the axial direction of the threaded rod of the limiting screw 320.

[0062] In some embodiments, the number of the pressing plates 310 is at least two, and the at least two pressing plates 310 are disposed along the circumference of the mounting seat 220 .

[0063] For example, the number of pressure plates 310 can be two or more. Taking two pressure plates 310 as an example, the two pressure plates 310 are arranged circumferentially around the mounting seat 220, and the two pressure plates 310 are symmetrically arranged about the center of the mounting seat 220. Taking four pressure plates 310 as an example, the four pressure plates 310 are evenly spaced around the circumference of the mounting seat 220.

[0064] In some embodiments, the fastening assembly 300 further includes at least one tension spring 330 , and at least one tension spring 330 is provided at the bottom of one end of a pressure plate 310 close to the base 100 , and the pressure plate 310 is connected to the top of the base 100 through the tension spring 330 .

[0065] For example, the number of the tension springs 330 may be one or more, which is not limited herein. One or more tension springs 330 are provided at the bottom of one end of the pressing plate 310 close to the base 100 , which is not limited herein.

[0066] It should be noted that the block 311 at one end of the pressure plate 310 is engaged in the slot 221. According to the above, there is a height difference between the top surface of the mounting seat 220 and the top surface of the base 100. When the height difference changes, the tension spring 330 will adaptively expand and contract according to the change in the difference, thereby effectively ensuring that the block 311 at one end of the pressure plate 310 can be better engaged in the slot 221.

[0067] In some embodiments, the fastening assembly 300 further includes at least one support plate 340 , all the tension springs 330 of one pressing plate 310 are connected to one support plate 340 , and the tension springs 330 are connected to the base 100 through the support plate 340 .

[0068] Exemplarily, the number of the support plates 340 may be one or more, which is not limited here; preferably, one pressing plate 310 corresponds to one support plate 340 .

[0069] It should be noted that the tension spring 330 has relatively few connection points for connection with other components. Therefore, if the bottom end of the tension spring 330 is directly connected to the base 100, the pressure plate 310 will block the upper end of the tension spring 330, and the pressure plate 310 will cause further inconvenience to the connection between the lower end of the tension spring 330 and the base 100. In this way, by providing a support plate 340, the support plate 340 is pre-set at the bottom end of the tension spring 330. After the mounting seat 220 is installed in the mounting groove 400, the support plate 340 is connected to the top surface of the base 100. This connection method includes but is not limited to welding, bonding, or screw connection. In summary, the contact surface of the support plate 340 is conducive to the contact and connection between the support plate 340 and the base 100.

[0070] See also Figure 3 and Figure 4 In some embodiments, at least one locking protrusion 222 is provided on the peripheral side of the mounting seat 220, and at least one vertical guide groove 410 extending from top to bottom is provided on the inner wall of the mounting groove 400, and a locking groove 420 is provided at the bottom of the vertical guide groove 410 along the circumference of the mounting groove 400.

[0071] When the mounting seat 220 is installed in the mounting groove 400, a locking protrusion 222 enters the vertical guide groove 410 from the top of a vertical guide groove 410 downward. When the locking protrusion 222 reaches the bottom of the vertical guide groove 410, the mounting seat 220 rotates along the circumference of the mounting groove 400 so that the locking protrusion 222 is locked in the locking groove 420.

[0072] For example, the number of the engaging protrusions 222 can be one or more, which is not limited here. The number of the vertical guide grooves 410 can be one or more, which is not limited here. The vertical guide grooves 410 are arranged on the inner wall of the mounting groove 400 along the vertical direction.

[0073] It should be noted that the engaging protrusions 222 are provided at the bottom edge of the peripheral side of the mounting base 220. In this embodiment, two engaging protrusions 222 are used as an example, and the two engaging protrusions 222 are symmetrically arranged relative to the center of the mounting base 220. Therefore, it can be seen that the number of the vertical guide grooves 410 is the same as the number of the engaging protrusions 222, which is also two.

[0074] At this time, the process of connecting the engaging protrusions 222 and the vertical guide grooves 410 is as follows: when the mounting base 220 is installed in the mounting groove 400, one engaging protrusion 222 is set in one vertical guide groove 410. When the mounting base 220 moves downward until it contacts the bottom of the mounting groove 400, the engaging protrusion 222 moves from the top to the bottom of the vertical guide groove 410. Then, when the mounting base 220 is rotated, the two engaging protrusions 222 are respectively engaged in the corresponding engaging grooves 420, so that the mounting base 220 cannot be separated upward from the mounting groove 400.

[0075] In other embodiments, the vertical guide groove 410 is provided obliquely on the inner wall of the mounting groove 400, that is, the vertical guide groove 410 forms a slope on the inner wall of the mounting groove 400. In this way, when the mounting seat 220 is installed in the mounting groove 400, the engaging protrusions 222 are guided by the vertical guide groove 410 to enter the mounting groove 400 obliquely. However, the mounting seat 220 rotates after reaching the bottom of the mounting groove 400 so that the engaging protrusions 222 are respectively engaged with the corresponding engaging grooves 420.

[0076] In addition, to ensure the connection between the clamping protrusion 222 and the mounting base 220, a connecting ring is provided on the bottom edge of the side of the mounting base 220. Preferably, the thickness of the connecting ring is equal to the thickness of the clamping protrusion 222. The clamping protrusion 222 is provided on the side of the connecting ring away from the mounting base 220.

[0077] Alternatively, the detachable mounting method between the mounting seat 220 and the mounting groove 400 may be that the mounting seat 220 and the mounting groove 400 are threadedly connected.

[0078] In some embodiments, at least two reinforcement blocks 110 are provided on the bottom of the peripheral side of the base 100;

[0079] At least two positioning bolts 600 are also included, one positioning bolt 600 passing through the reinforcing block 110 to be fixed to an external fixture.

[0080] And / or, at least two reinforcement blocks 110 are provided on the bottom of the peripheral side of the base 100 .

[0081] The reinforcement block 110 further includes at least two positioning bolts 600 and at least two washers 700 . One positioning bolt 600 passes through the reinforcement block 110 to be fixed to an external fixture.

[0082] Each positioning bolt 600 is equipped with a washer 700 , and the washer 700 is used to be placed between the positioning bolt 600 and the reinforcement block 110 .

[0083] Exemplarily, the number of the reinforcement blocks 110 may be two or more, which is not limited here.

[0084] It should be noted that the base 100 is a quadrilateral. When there are two reinforcement blocks 110, one reinforcement block 110 is positioned at the midpoint of each of the two opposing bottom edges of the base 100. This way, the two reinforcement blocks 110 symmetrically secure the base 100, enhancing the stability of the base 100 during installation. For example, in a photovoltaic power station, the base 100 is typically installed on the roof of the power room, so the locating bolts 600 are secured to the power room. When there are four reinforcement blocks 110, they are positioned at the four corners of the base 100.

[0085] In addition, the gasket 700 is an annular ring that is sleeved on the threaded rod of the positioning bolt 600 to cushion between the bottom of the screw head of the positioning bolt 600 and the top of the reinforcement block 110. Preferably, the gasket 700 is plastic and is used to prevent the screw head from squeezing the reinforcement block 110.

[0086] In some embodiments, the lightning protection assembly 200 further includes a fixing rod 230, which is disposed on the top of the mounting base 220, and the lightning rod 210 is disposed on the top of the fixing rod 230.

[0087] Exemplarily, the fixing rod 230 is a cylindrical rod, the bottom end of the fixing rod 230 can be detachably set on the top of the mounting seat 220, and the lightning rod 210 can be detachably set on the top of the fixing rod 230; in this way, the lightning protection assembly 200 can be disassembled into smaller units. When a unit is damaged, only the unit can be replaced, further reducing maintenance costs.
