[0048] Example 1:

[0049] like Figures 1 to 11As shown, this embodiment provides a lightning protection device, which includes a base 1, three sets of fixed seat assemblies 2, a first lightning arrester 3, a second lightning arrester 4, a circuit breaker disconnecting mechanism 5 and three sets of socket assemblies 6. The base 1 is provided with three sets of fixed seat assemblies 2 in sequence along the X-axis direction. The fixed seat assembly 2 includes a fixed seat 21 and a protective frame 22. The protective frame 22 is movably mounted on the fixed seat 21. The fixed seat 21 is provided with a plurality of threaded holes. The protective frame 22 is used to open or block the threaded holes; the bottom of the first lightning arrester 3, the second lightning arrester 4, the circuit breaker disconnecting mechanism 5 and the three sets of socket assemblies 6. A socket assembly 6 is respectively provided at the bottom of the lightning arrester 4 and the bottom of the circuit breaker breaking mechanism 5. The socket assembly 6 includes a socket 61. The socket 61 is provided with a plurality of connecting parts 64. The connecting parts 64 correspond to the threaded holes one by one. A touch seat 62 is provided at the bottom of the socket 61. The touch seat 62 is used to push open the protective frame 22. The bolt passes through the connecting part 64 and is inserted into the threaded hole to fix the socket 61 to the fixed seat 21. The first lightning arrester 3, the second lightning arrester 4 and the circuit breaker breaking mechanism 5 are arranged in sequence along the X-axis direction.

[0050] Specifically, a socket assembly 6 is fixedly installed at the bottom of each of the first lightning arrester 3, the second lightning arrester 4 and the circuit breaker disconnecting mechanism 5. During the installation process, the first lightning arrester 3 is inserted and fixed to the first group of fixed seat assembly 2 through the first group of socket assembly 6, the second lightning arrester 4 is inserted and fixed to the second group of fixed seat assembly 2 through the second group of socket assembly 6, and the circuit breaker disconnecting mechanism 5 is inserted and fixed to the third group of fixed seat assembly 2 through the third group of socket assembly 6. Since the three groups of fixed seat assemblies 2 are all fixedly installed on the base 1 in advance, the intervals between the three groups of fixed seat assemblies 2 will not change, thereby ensuring that the intervals between the first lightning arrester 3 and the second lightning arrester 4 and the intervals between the second lightning arrester 4 and the circuit breaker disconnecting mechanism 5 will not change during the installation process, thereby ensuring the installation accuracy and the lightning protection effect.

[0051] The first group of socket components 6 is fixedly mounted on the bottom of the first lightning arrester 3, the second group of socket components 6 is fixedly mounted on the bottom of the second lightning arrester 4, and the third group of socket components 6 is fixedly mounted on the bottom of the circuit breaker breaking mechanism 5. When the lightning arrester of this embodiment is used, the base 1 is fixedly mounted on the power equipment, and the three groups of fixed seat components 2 are fixedly mounted on the base 1. When the first lightning arrester 3 needs to be replaced, the first group of socket components 6 and the first lightning arrester 3 are replaced together. When the socket 61 is close to the fixed seat 21, the trigger seat 62 moves the protective frame 22 from Push it open on the threaded hole. When the connecting part 64 is aligned with the threaded hole, pass the bolt through the connecting part 64 and the threaded hole, and use the bolt to fix the socket 61 to the fixing base 21 to complete the installation of the first lightning arrester 3. The installation process of the second lightning arrester 4 and the circuit breaker opening mechanism 5 refers to the installation process of the first lightning arrester 3, and will not be repeated in detail in this embodiment. When the socket 61 is separated from the fixing base 21, the protective frame 22 blocks the threaded hole to prevent dust and impurities from accumulating in the threaded hole, and to prevent dust and impurities from accumulating in the threaded hole and affecting the subsequent installation accuracy.

[0052] Optionally, the fixing seat 21 is provided with a positioning groove 211, and the protective frame 22 includes a transmission plate 223 extending into the positioning groove 211. A first spring 23 is provided between the transmission plate 223 and the side wall of the positioning groove 211. The first spring 23 is used to drive the protective frame 22 to block the threaded hole.

[0053] When the trigger seat 62 pushes the protective frame 22 away from the threaded hole, the first spring 23 elastically deforms. When the trigger seat 62 is separated from the protective frame 22, the first spring 23 has elastic potential energy to return to its original shape and drive the protective frame 22 to cover the threaded hole. The positioning groove 211 is used to limit the movement distance of the transmission plate 223 to prevent the transmission plate 223 from separating from the first spring 23.

[0054] Optionally, the protective plate 221, the pushing plate 222 and the transmission plate 223 are an integrated structure.

[0055] Optionally, a receiving groove 212 is provided on the top of the fixing seat 21 , the positioning groove 211 and the threaded hole are both located at the bottom of the receiving groove 212 , and the protective frame 22 is received in the receiving groove 212 .

[0056] In this embodiment, each mounting assembly 2 includes two protective frames 22, which are spaced apart within the receiving slot 212, forming an insertion gap between the two protective frames 22. The trigger seat 62 is inserted through the insertion gap and pushes the two protective frames 22 apart. When the socket assembly 6 and the mounting assembly 2 are separated, the two protective frames 22 are close to each other and separated to form an insertion gap, which facilitates subsequent installation of the socket assembly 6. When the trigger seat 62 extends into the insertion gap, the two protective frames 22 are pushed away from each other until the threaded hole is fully exposed.

[0057] In this embodiment, there are four threaded holes on the fixing base 21, two of which are located below one protective frame 22, and the other two are located below another protective frame 22. The protective frame 22 also includes two protective plates 221, and the two protective plates 221 cover the top of the two threaded holes one by one.

[0058] After the two protective frames 22 are separated from each other, four threaded holes are exposed. The four connecting parts 64 on the socket 61 are aligned with the four threaded holes. The installer then passes four bolts through the four connecting parts 64 and the four threaded holes respectively.

[0059] Optionally, the protective frame 22 further includes a push plate 222, a protective plate 221 disposed above the push plate 222, and a transmission plate 223 disposed below the push plate 222. The side of the trigger seat 62 facing the push plate 222 is an inclined surface, which is used to push against the push plate 222. When the trigger seat 62 descends relative to the push plate 222, the inclined surface slides in contact with the end of the push plate 222, thereby pushing the push plate 222.

[0060] Optionally, a limiting head 63 is further provided at the bottom of the socket 61 , a limiting groove is provided on the fixing seat 21 , and the limiting head 63 is inserted into the limiting groove.

[0061] The lightning arrester is installed at a higher position on the power equipment, and the installer needs to install the first lightning arrester 3 or the second lightning arrester 4 or the circuit breaker tripping mechanism 5 while ensuring his own safety. For example, when installing the first group of socket components 6 and the first lightning arrester 3, when the installer brings the socket 61 close to the fixed seat 21, the limit head 63 is inserted into the limit groove, and the limit groove limits the limit head 63 to prevent the fixed seat assembly 2 and the first lightning arrester 3 from shaking as a whole, ensuring that the installer can easily tighten the bolts.

[0062] Optionally, a slot 631 is formed on the side wall of the limiting head 63 , and the fixing seat assembly 2 further includes a plug 24 and a second spring 25 . The second spring 25 is arranged between the plug 24 and the fixing seat 21 , and the second spring 25 is used to drive the plug 24 to be inserted into the slot 631 .

[0063] When the limit head 63 is inserted into the limit groove, the limit head 63 contacts the plug 24, and the second spring 25 undergoes elastic changes. After the limit head 63 is fully inserted into the limit groove, the plug 24 is driven by the second spring 25 to insert into the slot 631. The plug 24 limits the limit head 63 in the limit groove to prevent the limit head 63 from detaching from the limit groove.

[0064] Optionally, a bulge 241 is provided on the outside of the plug 24, and the bulge 241 extends to the outside of the fixing seat 21, so that the installer can pull the bulge 241 to disengage the plug 24 from the slot 631, thereby facilitating the installer to disengage the limit head 63 from the limit groove.

[0065] Optionally, a mounting bracket 7 is provided on the base 1, and the fixing base assembly 2 for supporting the circuit breaker tripping mechanism 5 is mounted on the mounting bracket 7. A first discharge head 51 is provided on the top of the circuit breaker tripping mechanism 5, and a second discharge head 41 is provided on the top of the second lightning arrester 4. The first discharge head 51 and the second discharge head 41 are opposite and spaced apart. The mounting bracket 7 is used to raise the installation height of the circuit breaker tripping mechanism 5 so that the first discharge head 51 and the second discharge head 41 are opposite.

[0066] Optionally, a tilting platform 8 is provided on the base 1 , and the fixing seat assembly 2 for supporting the first lightning arrester 3 is installed on the tilting platform 8 .

[0067] Example 2:

[0068] The difference between the lightning protection device provided in this embodiment and the lightning protection device provided in the first embodiment is that each set of fixing seat components 2 in this embodiment includes a protective frame 22 movably disposed in the receiving groove 212 .

[0069] Furthermore, the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of the present invention.
