[0029] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The embodiment of the present invention provides a high-voltage power grid lightning arrester that is easy to disassemble and install. Figure 1-11 As shown, the high-voltage power grid lightning arrester that is easy to disassemble and install includes: a lightning arrester main body 1, a voltage-equalizing ring 2 is provided on the top, a pressure release plate 60 is provided in the middle, and an insulating seat 3 is provided at the bottom; an assembly box 4 is provided at the bottom of the insulating seat 3, and a mounting structure for mounting the lightning arrester main body 1 is provided in the assembly box 4; a driving structure, the driving structure is installed in the assembly box 4, and is used to drive the mounting structure; a limiting mechanism is provided on the assembly box 4, and is used to limit the voltage-equalizing ring 2.

[0031] In this embodiment, the insulating seat 3 at the bottom of the arrester body 1 is placed on the mounting structure inside the assembly box 4. When the arrester needs to be installed, the drive mechanism inside the assembly box 4 is activated, driving the mounting structure to raise the arrester body 1. The limiting mechanism on the assembly box 4 is then used to limit and fix the equalizing ring 2 at the top of the arrester body 1. During disassembly, the limiting mechanism on the equalizing ring 2 is first released, and then the drive mechanism drives the mounting structure to descend, thereby achieving disassembly of the arrester body 1.

[0032] Compared to traditional lightning arresters, this invention significantly simplifies the installation and removal process. During routine maintenance, there is no need to use multiple specialized tools to tighten or loosen bolts, reducing the time and manpower consumed during maintenance. By quickly completing installation and removal, it can effectively shorten power outage maintenance time, reduce the impact of power outages on power supply, reduce the inconvenience caused to production and life, and reduce economic losses.

[0033] The present invention relies on the cooperation between the installation structure, the drive structure in the assembly box 4 and the limiting mechanism on the assembly box 4, and the overall structural design is reasonable, which not only ensures the stability of the installation of the lightning arrester body 1, but also achieves the purpose of easy disassembly and installation, and has a significant promoting effect on the design optimization of high-voltage power grid lightning arresters.

[0034] In a further preferred embodiment of the present invention, the mounting structure includes: a first mounting plate 5 and a mounting seat 6, the first mounting plate 5 is fixed in the assembly box 4, and the mounting seat 6 is fixed on the first mounting plate 5; a first rotating shaft 7 assembled on the mounting seat 6 through a bearing; a limit seat 8 and a limit cover 9, the limit seat 8 is fixed on the first rotating shaft 7, and the limit cover 9 is fixed to the limit seat 8 by screws; a T-shaped block 10 that passes through the limit cover 9 and is inserted into the limit seat 8, and the top end of the T-shaped block 10 passes through the assembly box 4 and is fixedly connected to the insulating seat 3.

[0035] In this embodiment, when installing the arrester, the T-shaped block 10 is precisely aligned with the slot on the stop cover 9 and smoothly inserted. Subsequently, the drive mechanism within the assembly box 4 is activated, driving the first rotating shaft 7 to rotate clockwise. Since the stop seat 8 is rigidly connected to the first rotating shaft 7, the stop seat 8 will simultaneously rotate 90°. During this process, the stop cover 9 rotates with the stop seat 8, causing the slot on the stop cover 9 to intersect with the T-shaped block 10, thus firmly locking and limiting the T-shaped block 10.

[0036] When the arrester needs to be disassembled, the drive mechanism is activated, driving the first rotating shaft 7 to rotate counterclockwise to reset. As the first rotating shaft 7 rotates, the limit seat 8 and the limit cover 9 rotate synchronously in the opposite direction until the slot on the limit cover 9 is realigned with the T-shaped block 10, releasing the locking limit of the T-shaped block 10. At this point, the operator only needs to pull up the T-shaped block 10 vertically and smoothly to smoothly separate the arrester body 1 from the assembly box 4.

[0037] During the installation process, the limiting component is locked by rotating the shaft, and unlocked by reverse rotation during disassembly, avoiding the tedious operation of tightening and loosening the bolts, greatly shortening the maintenance time, reducing labor costs, and minimizing the impact of power outages on the power supply. Moreover, this simple and orderly operation process effectively reduces the maintenance error rate and ensures the accuracy and efficiency of the maintenance work. By utilizing the unique cooperation between the limiting cover 9 and the T-shaped block 10, as well as the close connection between the various components, the lightning arrester body 1 is quickly and stably installed and disassembled. The various components have clear division of labor and strong synergy, which not only ensures the stability of the equipment operation, but also further highlights the advantages of the lightning arrester of the present invention in terms of operational convenience and structural reliability.

[0038] In a further preferred embodiment of the present invention, the driving structure includes: a ring gear 11 fixedly mounted on the limit seat 8; a first rotating rod 12 assembled on the first mounting plate 5 through a bearing, a first gear 13 fixed on the first rotating rod 12, and the first gear 13 is engaged with the ring gear 11; a power assembly, the power assembly including a motor 38 and a transmission component arranged in the assembly box 4.

[0039] In this embodiment, when installing the arrester, the T-shaped block 10 is first inserted into the slot on the limit cover 9, and the motor 38 in the assembly box 4 is started. The motor 38 drives the first rotating rod 12 to rotate through the transmission component, and the first gear 13 on the first rotating rod 12 rotates accordingly. Because the first gear 13 engages with the ring gear 11 fixedly mounted on the limit seat 8, the limit seat 8 is driven to rotate 90 degrees, so that the slot on the limit cover 9 and the T-shaped block 10 are locked in a cross state, and then the insulating seat 3 at the bottom of the arrester body 1 is fixed to the top of the T-shaped block 10. When disassembling, the motor 38 is reversed, and the transmission component rotates the first rotating rod 12 in the opposite direction. The first gear 13 drives the ring gear 11 in the opposite direction to rotate, and the limit seat 8 and the limit cover 9 rotate in the opposite direction to reset. When the slot on the limit cover 9 is aligned with the T-shaped block 10, the T-shaped block 10 is pulled up to separate the arrester body 1.

[0040] The drive structure composed of the motor 38, the first rotating rod 12, the first gear 13 and the ring gear 11 realizes automated operation. Compared with manual operation, it further reduces the manpower consumption during the installation and removal process, improves the accuracy of the operation, and greatly shortens the maintenance time of the lightning arrester.

[0041] The drive structure is cleverly designed, with the ring gear 11 fixed to the limit seat 8 and the first gear 13 fixed to the first rotating rod 12. The two mesh with each other, cooperating with the motor 38 and transmission components to achieve stable and reliable power transmission. The tight connection and strong coordination of the various components not only ensure the smooth installation and removal of the lightning arrester body 1, but also improve the stability of the entire device operation, further highlighting the advantages of the lightning arrester of the present invention in terms of operational convenience and structural reliability.

[0042] In a further preferred embodiment of the present invention, the transmission component includes: a second mounting plate 39 fixed in the assembly box 4, a first transmission rod 40 is assembled on the second mounting plate 39 through a bearing, and the first transmission rod 40 is fixedly connected to the output shaft of the motor 38 through a coupling; an assembly plate 41 symmetrically fixed on the first mounting plate 5, a second transmission rod 42 is assembled on the assembly plate 41 through a bearing; fourth bevel teeth 43 are respectively fixed on the first transmission rod 40 and the second transmission rod 42 and meshed with each other; fifth bevel teeth 44 are respectively fixed on the second transmission rod 42 and the first rotating rod 12 and meshed with each other.

[0043] In this embodiment, when the motor 38 within the assembly box 4 is activated, the output shaft of the motor 38 rotates the first transmission rod 40, which is secured to it via a coupling. The fourth bevel gear 43 on the first transmission rod 40 meshes with the fourth bevel gear 43 on the second transmission rod 42, driving the second transmission rod 42 to rotate. The fifth bevel gear 44 on the second transmission rod 42 meshes with the fifth bevel gear 44 on the first rotating rod 12, thereby driving the first rotating rod 12 to rotate. The first gear 13 on the first rotating rod 12 rotates accordingly. Because the first gear 13 meshes with the ring gear 11 fixed to the stopper 8, the stopper 8 rotates 90°, locking the slot on the stopper cover 9 with the T-shaped block 10 in a cross-shaped configuration. This then secures the insulating seat 3 at the bottom of the arrester body 1 to the top of the T-shaped block 10. To disassemble, the motor 38 is reversed, transmitting power along the opposite path, causing the first rotating rod 12 to rotate in the opposite direction, driving the stopper 8 and stopper cover 9 to rotate in the opposite direction and reset. When the slot on the limit cover 9 is aligned with the T-shaped block 10, pull up the T-shaped block 10 to separate the arrester body 1;

[0044] The transmission components utilize a multi-stage bevel gear transmission, with each component having a clear division of labor and strong synergy. The coordination of the first and second transmission rods 40, 42, the motor 38, and the first rotating rod 12 ensures the stability and reliability of power transmission. The second mounting plate 39 and the assembly plate 41 provide excellent support and fixation for the various transmission components, making the entire drive structure layout rational and compact. This not only ensures smooth installation and removal of the arrester body 1, but also improves the operational stability of the entire device.

[0045] In a further preferred embodiment of the present invention, the limiting mechanism includes: a mounting shell 14 fixed on the assembly box 4; a first one-way screw 19 assembled on the assembly box 4 through a sealed bearing, a sleeve 15 is threadedly provided on the first one-way screw 19, and the top of the sleeve 15 passes through the mounting shell 14; a steerable mounting bracket 16 is arranged on the sleeve 15, and a limiting ring 18 is assembled on the mounting bracket 16 through a connecting plate 17, and the limiting ring 18 is used to press the equalizing ring 2; a sixth bevel tooth 46 and a seventh bevel tooth 47 are respectively fixed on the second transmission rod 42 and the first one-way screw 19, and the sixth bevel tooth 46 is meshed with the seventh bevel tooth 47.

[0046] In this embodiment, after the arrester body 1 is installed, the equalizing ring 2 is then installed thereon, and then the motor 38 is started. The output shaft of the motor 38 drives the first transmission rod 40 to rotate, which in turn drives the second transmission rod 42 to rotate via the fourth bevel gear 43. On the one hand, the second transmission rod 42 drives the first rotating rod 12 to rotate via the fifth bevel gear 44, thereby achieving rotation locking of the limit seat 8. On the other hand, the sixth bevel gear 46 on the second transmission rod 42 engages with the seventh bevel gear 47 on the first one-way screw 19, driving the first one-way screw 19 to rotate. The sleeve 15 on the first one-way screw 19 moves downward due to the action of the thread, and the mounting bracket 16 drives the limit ring 18 close to the equalizing ring 2 and presses it firmly.

[0047] During disassembly, the motor 38 rotates in the reverse direction, and the second transmission rod 42 rotates in the reverse direction, driving the first one-way screw 19 to rotate in the reverse direction, the sleeve 15 rises, and the limiting ring 18 is separated from the pressure equalizing ring 2 to achieve unlocking.

[0048] The limiting mechanism is linked to the drive structure to achieve simultaneous limiting and fixing during the installation of the lightning arrester without the need for additional operations, which greatly improves the installation efficiency. The limiting ring 18 can be precisely adjusted through bevel gear transmission and thread lifting. The layout of the various components of the limiting mechanism is compact and reasonable. The mounting shell 14 provides guidance for the sleeve 15 to ensure its vertical lifting. The first one-way screw 19 assembled with a sealed bearing effectively prevents dust and water vapor from entering, thereby extending the service life of the equipment. The engagement of the sixth bevel gear 46 and the seventh bevel gear 47 enables stable transmission of power from the second transmission rod 42 to the first one-way screw 19. The entire limiting mechanism works closely with the drive structure and has strong synergy, which not only ensures the smooth installation and disassembly of the lightning arrester body 1, but also improves the stability of the operation of the entire device.

[0049] In a further preferred embodiment of the present invention, the assembly box 4 is equipped with a sealed door 45 with a door lock via hinges; a base plate is fixed to the bottom thereof, and mounting holes are symmetrically opened on the base plate.

[0050] In this embodiment, when the drive structure, limit mechanism, and other components within the assembly box 4 need to be inspected or maintained, the sealed door 45, which is hinged on the assembly box 4, is opened and pivoted open. After the inspection or maintenance work is completed, the sealed door 45 is closed and locked using a door lock. When installing the lightning arrester, the entire lightning arrester is secured to the desired installation location using the symmetrical mounting holes on the base plate and matching bolts and other fasteners.

[0051] The design of sealed door 45 greatly facilitates inspection and maintenance of the internal components of assembly box 4. The door lock enhances the safety of the equipment, preventing unauthorized operation by non-professionals and ensuring stable operation of the power system. The mounting holes on the base plate facilitate the installation and fixation of the lightning arrester device, improving installation efficiency. The symmetrical design ensures the stability of the device installation. In addition, when sealed door 45 is closed, it effectively prevents dust, moisture, and other external impurities from entering assembly box 4, protecting the precision components within and extending the overall service life of the equipment.

[0052] In a further preferred embodiment of the present invention, a slot is provided on the limit cover 9 , and the slot is adapted to fit the T-shaped block 10 . A through opening adapted to fit the T-shaped block 10 is provided on the top of the assembly box 4 .

[0053] In this embodiment, the slot on the limit cover 9 is adapted to the T-shaped block 10, and the top opening of the assembly box 4 provides a channel for the insertion and removal of the T-shaped block 10, which greatly simplifies the installation and disassembly process of the lightning arrester body 1. The precisely adapted structural design reduces the risk of component misalignment during installation, reduces human errors, ensures the accuracy and safety of operation, and thus reduces the impact of improper maintenance on the power system.

[0054] The slotted opening of the limit cover 9 cooperates with the top opening of the assembly box 4, ensuring smooth entry and exit of the T-shaped block 10 while maintaining the compactness of the internal structure of the assembly box 4. This design works in conjunction with the drive structure and limit mechanism within the assembly box 4 to ensure a tighter connection between the various components and a more reasonable layout.

[0055] In a further preferred embodiment of the present invention, a height-adjustable bracket 33 is provided on the mounting frame 16 for supporting the equalizing ring 2 during disassembly, and a protective pad 61 is provided on the bracket 33 .

[0056] In this embodiment, when disassembling the arrester body 1, the motor 38 is started to reverse, driving the first one-way screw 19 to rotate in the opposite direction, and the sleeve 15 rises immediately; in this process, the height of the bracket 33 on the mounting frame 16 is synchronously adjusted to make it rise to the appropriate position; when the limit ring 18 is separated from the equalizing ring 2, the bracket 33 firmly holds the equalizing ring 2 and continues to move upward; then, according to the actual space and operation requirements on site, the mounting frame 16 is adjusted in direction to avoid the bracket 33 and the equalizing ring 2 from being blocked and hindering subsequent operations. After the motor 38 continues to drive the limit cover 9 to rotate in the opposite direction and reset, and the straight hole on the limit cover 9 is aligned with the T-shaped block 10, the staff pulls out the T-shaped block 10 upward through the top opening of the assembly box 4, and successfully removes the arrester body 1 that has been released from the limit. Since the bracket 33 is provided with a protective pad 61, the protective pad 61 fits tightly with the equalizing ring 2 during the lifting process to prevent the equalizing ring 2 from being damaged;

[0057] The bracket 33 cooperates with the steerable and adjustable mounting frame 16, which not only enhances the stability of the support for the equalizing ring 2, but also gives the device a high degree of flexibility as a whole. This structure is closely related to the limiting mechanism and driving structure in the assembly box 4 to form an organic whole that works together, making the collaboration between the various components smoother and more efficient.

[0058] In a further preferred embodiment of the present invention, a guide opening is provided on the mounting shell 14 , and the guide opening is adapted to fit with the sleeve plate 15 . The sleeve plate 15 is provided with a thread groove adapted to fit with the first one-way screw 19 .

[0059] In this embodiment, since the sleeve plate 15 is provided with a thread groove adapted to the first one-way screw 19, the sleeve plate 15 is lifted and lowered along the first one-way screw 19 under the action of the thread, and the sleeve plate 15 is lifted and lowered smoothly along the guide opening on the mounting shell 14, and the guide opening serves as a limiting guide.

[0060] In a further preferred embodiment of the present invention, a groove is provided on the limiting seat 8 , the inner diameter of the groove is larger than that of the T-shaped block 10 , and a socket adapted to fit the bolt is provided on the limiting cover 9 .

[0061] In this embodiment, the groove design on the limiting seat 8 can ensure that the T-shaped block 10 can be normally inserted therein, and the inner diameter of the groove is larger than the T-shaped block 10, which can ensure that the limiting seat 8 can rotate normally.

[0062] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0063] In another embodiment of the present invention, a steering mechanism is provided on the mounting shell 14 and the sleeve plate 15 for adjusting the steering of the mounting frame 16, and the steering mechanism includes: a second rotating shaft 20 assembled on the sleeve plate 15 through a bearing, and the top of the second rotating shaft 20 is fixedly connected to the mounting frame 16; a second gear 23 fixed on the second rotating shaft 20; a spline cylinder 21 assembled in the mounting shell 14 through a bearing, a spline rod 22 is provided in the spline cylinder 21, and a third gear 24 is fixed on the spline rod 22, and the third gear 24 is meshed with the second gear 23; a second rotating rod 26 assembled in the mounting shell 14 through a bearing, and the second rotating rod 26 and the spline cylinder 21 are fixed with first bevel teeth 28 that mesh with each other; a fourth gear 27 fixed on the second rotating rod 26; a first rack 25 fixed on the sleeve plate 15 and meshing with the fourth gear 27; and a protective shell 29 fixed on the mounting frame 16 for shielding the third gear 24.

[0064] In this embodiment, during the installation or removal of the arrester body 1, the sleeve plate 15 will rise or fall with the first one-way screw 19. When the sleeve plate 15 rises, the first rack 25 fixed on the sleeve plate 15 rises accordingly. When the first rack 25 engages with the fourth gear 27 fixed on the second rotating rod 26 and continues to rise, it will drive the second rotating rod 26 to rotate. The first bevel teeth 28 on the second rotating rod 26 engage with the first bevel teeth 28 on the spline cylinder 21, causing the spline cylinder 21 to rotate, and the spline rod 22 in the spline cylinder 21 rotates accordingly. The third gear 24 on the spline rod 22 engages with the second gear 23 fixed on the second rotating shaft 20, thereby driving the second rotating shaft 20 to rotate. Since the top of the second rotating shaft 20 is fixedly connected to the mounting frame 16, the mounting frame 16 can achieve steering adjustment; the steering mechanism can automatically achieve steering adjustment of the mounting frame 16 during the lifting and lowering process of the sleeve plate 15, greatly improving the convenience of installing and removing the arrester.

[0065] The components of the steering mechanism are compactly and reasonably arranged. Through bearing assembly and spline connection, the components can be ensured to rotate flexibly and stably. The transmission cooperation between the first rack 25 and the fourth gear 27 and the first bevel gear 28 realizes the lifting movement of the sleeve plate 15 to the steering movement of the mounting frame 16.

[0066] In another embodiment of the present invention, an adjustment mechanism for regulating the lifting and lowering of the bracket 33 is provided on the mounting frame 16 and the mounting shell 14, and the adjustment mechanism includes: a second one-way screw 31 assembled on the mounting frame 16 through a bearing, an adjustment plate 32 is threadedly sleeved on the second one-way screw 31, and one end of the adjustment plate 32 is fixedly connected to the bracket 33; a third rotating rod 34 assembled on the mounting frame 16 through a bearing, a second bevel gear 36 and a third bevel gear 37 are respectively fixed on the third rotating rod 34 and the second one-way screw 31, and the second bevel gear 36 is meshed with the third bevel gear 37 for transmission; a second rack 30 fixed on the mounting shell 14; a fifth gear 35 fixed on the third rotating rod 34, and the fifth gear 35 can be engaged with and separated from the second rack 30.

[0067] In this embodiment, during the process of disassembling the arrester body 1, when the motor 38 is started to rotate the first one-way screw 19, the sleeve plate 15 rises and drives the mounting bracket 16 to rise, the fifth gear 35 climbs along the second rack 30, and the fifth gear 35 rotates the third rotating rod 34 to rotate, which can drive the second one-way screw 31 to rotate, and drives the adjustment plate 32 to move, and the bracket 33 moves accordingly to lift the pressure equalizing ring 2 to a certain stroke height. As the sleeve plate 15 continues to rise, the first rack 25 fixed on the sleeve plate 15 engages with the fourth gear 27 fixed on the second rotating rod 26, driving the second rotating rod 26 to rotate. The second rotating rod 26 rotates the spline cylinder 21 through the first bevel gear 28, and then drives the second rotating shaft 20 to rotate, and the mounting bracket 16 turns accordingly, turning the lifted pressure equalizing ring 2 to one side, as shown in FIG. Figure 8 As shown in , it is avoided to hinder the removal of the arrester body 1. When the mounting frame 16 is turned, the fifth gear 35 and the second rack 30 are in a separated state;

[0068] During installation, on the contrary, the motor 38 rotates to drive the sleeve plate 15 to descend, so that the fifth gear 35 re-engages with the second rack 30. As the sleeve plate 15 descends, the drive assembly moves downward and resets, and the equalizing ring 2 returns to the positioned arrester body 1;

[0069] The adjustment mechanism and the steering mechanism work closely together to achieve the regulation of the height of the bracket 33 and the position of the equalizing ring 2. This collaborative working mode greatly simplifies the installation and disassembly process of the lightning arrester.

[0070] In another embodiment of the present invention, a lifting mechanism is provided on the assembly box 4 for lifting the unlocked arrester body 1 out of the assembly box 4, and the lifting mechanism includes: a guide groove 48 fixed on the assembly box 4, an assembly frame 49 is slidably installed in the guide groove 48, an assembly shell 51 is fixed on the assembly frame 49, and lifting plates 54 with adjustable spacing are symmetrically provided on the assembly shell 51; a third one-way screw 50 is assembled on the assembly box 4 through a sealed bearing, the bottom end of the third one-way screw 50 is connected to the first rotating rod 12 through a coupling, and the top thread of the third one-way screw 50 passes through the assembly frame 49.

[0071] In this embodiment, when disassembling the arrester body 1, the motor 38 is started to drive the first rotating rod 12 to rotate, completing the unlocking process of the arrester body 1. Since the bottom end of the third one-way screw 50 is connected to the first rotating rod 12 through a coupling, the first rotating rod 12 drives the third one-way screw 50 to rotate. The top thread of the third one-way screw 50 passes through the assembly frame 49. Under the action of the thread, the assembly frame 49 rises along the guide groove 48, and the assembly shell 51 and the lifting plate 54 rise accordingly. At the same time, the spacing between the lifting plates 54 changes and contacts the pressure release plate 60. When the lifting plate 54 rises, the arrester body 1 rises together with the assembly shell 51, detaches from the assembly box 4, and completes the extraction action. Then the personnel removes the arrester body 1 that needs to be replaced on the lifting plate 54 and replaces it with a new one.

[0072] The lifting mechanism is closely linked to the unlocking operation to realize the automatic lifting and lowering of the arrester body 1 during the disassembly and installation process, without the need for manual pulling out and putting in, which greatly reduces the labor intensity of the staff.

[0073] In another embodiment of the present invention, a linkage mechanism for adjusting the distance between the two lifting plates 54 is provided on the assembly shell 51, the assembly frame 49 and the guide groove 48, and the linkage mechanism includes: a bidirectional screw 52 assembled in the assembly shell 51 through a bearing, two adjustment frames 53 are threadedly sleeved on the bidirectional screw 52, ​​and the two adjustment frames 53 are fixedly connected to the corresponding lifting plates 54; a guide rod 55 fixed in the assembly shell 51, and the guide rod 55 passes through the two lifting plates 54; a third transmission rod 56 assembled on the assembly frame 49 through a bearing, and the third transmission rod 56 and the bidirectional screw 52 are transmitted through an eighth bevel gear 57 that meshes with each other; a third rack 58 fixed on the guide groove 48; a sixth gear 59 fixed on the third transmission rod 56, and the sixth gear 59 meshes with the third rack 58.

[0074] In this embodiment, during the disassembly of the arrester body 1, when the motor 38 is started, the motor 38 drives the first rotating rod 12 to rotate, driving the third one-way screw 50 to rotate synchronously, and the assembly frame 49 rises along the guide groove 48. During this process, the sixth gear 59 fixed on the third transmission rod 56 engages with the third rack 58 fixed on the guide groove 48, and the third transmission rod 56 rotates accordingly. The third transmission rod 56 drives the bidirectional screw 52 to rotate through the eighth bevel gear 57. Since the threaded sleeve on the bidirectional screw 52 is provided with two adjustment racks 53, and the two adjustment racks 53 are respectively fixedly connected to the corresponding lifting plates 54, the rotation of the bidirectional screw 52 automatically adjusts the spacing between the two lifting plates 54 to fit the pressure release plate 60. The arrester body 1 rises with the assembly shell 51 and detaches from the assembly box 4. The staff removes the old arrester body 1. The linkage mechanism closely cooperates with the lifting process of the arrester body 1 to achieve automatic adjustment of the spacing between the lifting plates 54, without the need for manual operation, further simplifying the assembly and unloading process of the arrester body 1.

[0075] To sum up, compared with the relevant technology, the automatic operation of unlocking and locking the lightning arrester body 1 is realized by means of the driving structure composed of the motor 38, transmission components, etc.; the limiting mechanism is linked with the driving structure to synchronously complete the limiting fixation of the equalizing ring 2; the adjusting mechanism, steering mechanism and lifting mechanism cooperate with each other to automatically control the height of the bracket 33, the steering of the mounting frame 16 and the lifting and lowering of the lightning arrester body 1, which greatly simplifies the installation and disassembly process, reduces labor intensity, shortens maintenance time, and reduces the impact of power outages on power supply; the sealing door 45 and base plate design facilitate equipment maintenance and installation, protect internal components, and extend the service life of the equipment.
