[0030] Embodiment 1

[0031] As Figures 1 to 8 shown;

[0032] Combined with the above content:

[0033] In order to facilitate the installation of lightning protection devices on power equipment of different sizes, the lightning protection device of this power equipment includes a power device main body 1. An installation component 2 is provided on the surface of the power device main body 1. A receiving shell 4 is fixedly connected to the surface of the installation component 2. A limiting shaft 5 is provided inside the receiving shell 4. A vibration component 6 is provided on the surface of the limiting shaft 5. One end of the vibration component 6 away from the limiting shaft 5 is provided with a lightning guiding component 3;

[0034] The installation component 2 includes an installation shell 214. Two limiting grooves are symmetrically opened inside the installation shell 214. And a moving sleeve 21 is provided inside each limiting groove. The moving sleeve 21 is slidably connected to the installation shell 214 through the limiting groove. An extension plate 22 is slidably connected inside each moving sleeve 21. A rotating groove is opened inside each extension plate 22. And a positioning shaft 212 is provided inside the rotating groove. The positioning shaft 212 is rotatably connected to the extension plate 22. A torsion spring A is sleeved on the surface of the positioning shaft 212. Two ends of the torsion spring A are fixedly connected to the positioning shaft 212 and the extension plate 22 respectively. A clamping plate 213 is provided inside the rotating groove. The clamping plate 213 is fixedly connected to the positioning shaft 212. The lightning guiding component 3 includes a lightning rod 33. A diversion copper wire 32 is fixedly connected to the surface of the lightning rod 33. Tooth plates 25 are fixedly connected to the surfaces of the two moving sleeves 21. The two tooth plates 25 are arranged in an interleaved parallel manner. And the toothed sides of the two tooth plates 25 are adjacent. A rotating hole is opened inside the installation shell 214. And a telescopic rod is provided inside the rotating hole. The telescopic rod is slidably connected to the installation shell 214 through the rotating hole. One end of the telescopic rod is fixedly connected to a tooth disc 23. A handle 24 is rotatably connected to the side of the tooth disc 23 away from the installation shell 214. A gear A26 is provided between the installation shell 214 and the moving sleeve 21. The gear A26 is fixedly connected to the telescopic rod. The gear A26 meshes with the two tooth plates 25. Two positioning grooves are symmetrically opened inside each moving sleeve 21. And two sprockets 28 are symmetrically provided inside each positioning groove. The sprocket 28 is rotatably connected to the moving sleeve 21. A chain 29 is provided inside each positioning groove. The chain 29 is sleeved on the surfaces of the two sprockets 28 and meshes with the sprockets 28. A connecting block A210 is fixedly connected to the side of each chain 29 away from the extension plate 22. The connecting block A210 is fixedly connected to the installation shell 214. Two connecting blocks B211 are symmetrically fixedly connected to the surface of each extension plate 22. The connecting block B211 is fixedly connected to the chain 29. A gear B27 is provided between the installation shell 214 and the moving sleeve 21. The gear B27 is located above the moving sleeve 21 on the side away from the gear A26. The gear B27 is rotatably connected to the installation shell 214 through a rotating shaft. The gear B27 meshes with the two tooth plates 25.

[0035] In this embodiment: When lightning protection equipment needs to be installed, place the installation shell 214 on the upper surface of the power device main body 1, and then apply force to the handle 24, so that the toothed disc 23 rotates inside the rotating hole through the telescopic rod, thereby driving the gear A 26 to rotate. The gear A 26 will drive the two toothed plates 25 to move in opposite directions, prompting the two moving sleeves 21 to slide in the installation shell 214 in opposite directions, thus realizing the expansion of the installation range and enabling it to be installed on the surfaces of power device main bodies 1 of different sizes. When the moving sleeve 21 moves, it will drive the two sprockets 28 to move, and the chain 29 engaged with the sprockets 28 will rotate inside the positioning groove due to the limit of the connecting block A 210, causing the connecting block B 211 fixedly connected to the sprocket 28 to drive the extension plate 22 to move, thereby further expanding the installation range. When the extension plate 22 moves a certain distance, the clamping plate 213 will not be limited, and it will rotate inside the rotating groove with the positioning shaft 212 as the axis through the torsion spring A until the clamping plate 213 is perpendicular to the extension plate 22. Then, reverse-rotate the toothed disc 23 to make the two clamping plates 213 move closer to the power device main body 1 and fit with the power device main body 1. Then, rotate the lightning rod 33 inside the receiving shell 4 through the limiting shaft 5 so that the lightning rod 33 is perpendicular to the receiving shell 4. Then, connect one end of the diversion copper wire 32 far from the lightning rod 33 to the ground, and the installation of the lightning protection device is completed. Through the cooperation of the internal components of the installation component 2, it is convenient to disassemble and assemble the lightning protection device, and by utilizing its telescopic characteristics, it has the characteristics of convenient transportation and storage.

[0036] Furthermore:

[0037] In an alternative embodiment, a toothed groove 215 is formed on the surface of the installation shell 214, and the toothed disc 23 is inserted into the toothed groove 215.

[0038] In this embodiment: When the two clamping plates 213 clamp the power device main body 1, press down the toothed disc 23 to make the telescopic rod contract, so that the toothed disc 23 is inserted into the toothed groove 215 to limit and lock the toothed disc 23, preventing the two clamping plates 213 from loosening the force applied to the power device main body 1 in the natural state and realizing more stable clamping.

[0039] Furthermore:

[0040] In an alternative embodiment, a buffer pad 7 is fixedly connected to one side of each clamping plate 213 close to the power device main body 1.

[0041] In this embodiment: when the two clamping plates 213 approach the main body 1 of the power device, the two buffer pads 7 will be attached to the surface of the main body 1 of the power device. Since the buffer pads 7 are made of rubber material, not only can the friction between the clamping plates 213 and the main body 1 of the power device be increased through the particularity of its material, making the clamping more firm, but also when lightning strikes the lightning rod 33, a small part of the current passing through the main body 1 of the power device can be blocked, preventing the parts inside the main body 1 of the power device from being damaged.

[0042] Furthermore:

[0043] In an alternative embodiment, the lightning rod 33 is located inside the receiving shell 4. One end of the lightning rod 33 is fixedly connected to a spring A65. The end of the spring A65 away from the lightning rod 33 is fixedly connected to the limiting shaft 5. A receiving groove 31 is formed on the surface of the lightning rod 33. The diversion copper wire 32 is located inside the receiving groove 31. Two fixing grooves 61 are symmetrically formed on the surface of the lightning rod 33. A current blocking block 63 is arranged inside each fixing groove 61. The current blocking block 63 is slidably connected to the lightning rod 33 through the fixing groove 61. A number of spring B62 are evenly arranged inside the fixing groove 61. The two ends of the spring B62 are respectively fixedly connected to the lightning rod 33 and the current blocking block 63. Two fixing shafts 9 are symmetrically and fixedly connected inside the receiving shell 4. Two sliding grooves 8 are symmetrically formed inside the limiting shaft 5. The fixing shaft 9 is inserted into the sliding groove 8. The fixing shaft 9 is slidably connected to the limiting shaft 5 through the sliding groove 8. The limiting shaft 5 is composed of a semi-cylinder and two discs. Arc-shaped grooves are formed at positions corresponding to the two discs inside the receiving shell 4. The two discs are inserted into the two arc-shaped grooves.

[0044] In this embodiment: when it is necessary to lift the lightning rod 33, a force is applied to the lightning rod 33 to make the limiting shaft 5 rotate on the surface of the fixing shaft 9. When the lightning rod 33 rotates out of the receiving shell 4, the spring A65 will extend the lightning rod 33 again due to its elastic potential energy, making the height of the lightning rod 33 higher and the lightning attracting effect better. Until the lightning rod 33 is rotated to an appropriate angle, the lightning rod 33 is pressed down to insert the discs on both sides of the limiting shaft 5 into the arc-shaped grooves. The fixing shaft 9 will slide inside the sliding groove 8 to position the lightning rod 33, realizing the lifting and fixing of the lightning rod 33. Then, one end of the diversion copper wire 32 is pulled out from the inside of the receiving groove 31 and connected to the ground. When the lightning rod 33 rotates out of the receiving shell 4, the two current blocking blocks 63 will be ejected from the inside of the fixing groove 61 due to the elastic potential energy of the spring B62, expanding the wind resistance of the lightning rod 33. When the wind blows towards the lightning rod 33, the two current blocking blocks 63 will be stressed, and thus vibrate through the characteristics of the spring B62, indirectly driving the lightning rod 33 to shake through the spring A65. Therefore, by using the vibration and shaking of the lightning rod 33, the dust and frost adsorbed on the surface of the lightning rod 33 can be shaken off, thereby extending the service life of the lightning rod 33.

[0045] Furthermore:

[0046] In an alternative embodiment, a flow dividing rod 64 is fixedly connected to one side of each flow blocking block 63 away from the spring B62.

[0047] In this embodiment: When the two flow blocking blocks 63 expand to both sides of the lightning rod 33, the two flow dividing rods 64 also expand, increasing the lightning attracting area of the lightning rod 33 and making the protection effect better.

[0048] Working principle and usage process of the present invention: When lightning protection equipment needs to be installed, place the installation shell 214 on the upper surface of the power device main body 1, and then apply force to the handle 24, so that the toothed disk 23 rotates inside the rotating hole through the telescopic rod, thereby driving the gear A 26 to rotate. The gear A 26 will drive the two toothed plates 25 to move in opposite directions, prompting the two moving sleeves 21 to slide in opposite directions inside the installation shell 214, thus realizing the expansion of the installation range and enabling it to be installed on the surfaces of power device main bodies 1 of different sizes. When the moving sleeve 21 moves, it will drive the two sprockets 28 to move, and the chain 29 engaged with the sprocket 28 will rotate inside the positioning groove due to the limitation of the connecting block A 210, causing the connecting block B 211 fixedly connected to the sprocket 28 to drive the extension plate 22 to move, thereby further expanding the installation range. When the extension plate 22 moves a certain distance, the clamping plate 213 will not be limited, and it will rotate inside the rotating groove with the positioning shaft 212 as the axis through the torsion spring A until the clamping plate 213 is perpendicular to the extension plate 22. Then, reverse-rotate the toothed disk 23 to make the two clamping plates 213 approach the power device main body 1 and fit with the power device main body 1. Then, rotate the lightning rod 33 through the limiting shaft 5 inside the accommodating shell 4 so that the lightning rod 33 is perpendicular to the accommodating shell 4. Then, connect the end of the diversion copper wire 32 far from the lightning rod 33 to the ground, and the installation of the lightning protection device is achieved. It is possible to realize the convenient disassembly and assembly of the lightning protection device by the cooperation of the internal components of the installation component 2, and utilize its telescopic characteristics to make it convenient for transportation and storage. When the two clamping plates 213 clamp the power device main body 1, press down the toothed disk 23 to make the telescopic rod contract, so that the toothed disk 23 is inserted into the toothed groove 215 to limit and lock the toothed disk 23, preventing the two clamping plates 213 from loosening the force applied to the power device main body 1 in the natural state and realizing more stable clamping. When the two clamping plates 213 approach the power device main body 1, the two buffer pads 7 will fit on the surface of the power device main body 1. Since the buffer pad 7 is made of rubber material, not only can the friction between the clamping plate 213 and the power device main body 1 be increased through the particularity of its material to make the clamping more firm, but also when lightning strikes the lightning rod 33, a small part of the current passing through the power device main body 1 can be blocked, preventing the parts inside the power device main body 1 from being damaged. When the lightning rod 33 needs to be propped up, apply force to the lightning rod 33 to make the limiting shaft 5 rotate on the surface of the fixed shaft 9. When the lightning rod 33 rotates out of the accommodating shell 4, the spring A 65 will extend the lightning rod 33 again due to its elastic potential energy, making the height of the lightning rod 33 higher and the lightning attracting effect better. Until the lightning rod 33 is rotated to an appropriate angle, press down the lightning rod 33 to make the discs on both sides of the limiting shaft 5 insert into the arc-shaped grooves, and the fixed shaft 9 will slide inside the sliding groove 8 to realize the positioning of the lightning rod 33, achieving the propping up and fixing of the lightning rod 33. Then, pull out one end of the diversion copper wire 32 from inside the accommodating groove 31,And it is connected to the ground. When the lightning rod 33 rotates out from the inside of the accommodation shell 4, the two flow-blocking blocks 63 will be ejected from the inside of the fixed groove 61 due to the elastic potential energy of the spring B62, expanding the wind resistance of the lightning rod 33. When the wind blows towards the lightning rod 33, the two flow-blocking blocks 63 will be stressed, and thus vibrate through the characteristics of the spring B62, indirectly driving the lightning rod 33 to shake through the spring A65. Therefore, by using the vibration and shaking of the lightning rod 33, the dust and frost adsorbed on the surface of the lightning rod 33 are shaken off, thereby extending the service life of the lightning rod 33. When the two flow-blocking blocks 63 expand towards both sides of the lightning rod 33, the two shunt rods 64 will also expand, increasing the lightning attracting area of the lightning rod 33, making the protection effect better.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
