[0009] Preferably, a conductive metal ring is provided on the outer side wall of the arrester, and a connection point for fixing a first wire is also provided on the arrester bracket, one end of the first wire is connected to the conductive metal ring, and the other end of the first wire is connected to the first energized solenoid.

[0010] Preferably, a bolt cavity is provided at the bottom of the placement groove, and the bolt cavity is connected to the first inner cavity through a transverse slot. A sliding plate slides in the transverse slot, one end of the sliding plate is connected to the first push plate, and a plurality of protrusions are provided on the sliding plate.

[0014] A method for using a tower lightning arrester bracket, the specific operating steps are as follows: S1: First, install the arrester with a base on the arrester bracket, then insert the fastening bolts on the base and fix them to the arrester bracket. Since the outer wall of the bolt cavity does not have a thread groove, the multiple protrusions on the sliding plug plate in the transverse slot cooperate with the fastening bolts to play a bolt matching role; S2: When thunderstorm occurs and the device is struck by lightning, the current will flow along the arrester, the conductive metal ring, the first wire, the first energized solenoid, the second wire, the third wire, and then out of the lightning protection cable.

[0015] The beneficial effects of the present invention are: The base of the present invention, which was originally placed in the lightning arrester bracket, vibrates and shakes violently under the bombardment of lightning, which will cause the base with the lightning arrester originally fastened by bolts to loosen, that is, the fastening bolts originally fastened by bolts will loosen, but under the action of lightning, the original fastening bolts will be driven to rotate downward, so the vibration and looseness caused by the bombardment of lightning will be re-pretightened, avoiding loosening caused by long-term use. At the same time, compared with the traditional fastening method, the disassembly method of this method is the same as the traditional disassembly method, does not increase the difficulty of disassembly, and is more convenient for high-altitude operation disassembly and replacement.

[0016] In the present invention, when the first relay is triggered to turn on, the second energized solenoid will generate a magnetic field and attract the lifting plate below to lift up. During the lifting process of the lifting plate, the current of the second energized solenoid will flow into the lightning protection auxiliary cable through the metal plate, the lifting plate and the connecting side plate. Then, this excess current will flow from the lightning protection auxiliary cable to the ground, and the excessive current will be conducted out of the lightning protection auxiliary cable, thereby completing the protection of the iron tower body and the high-voltage wires.

DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 9 A tower lightning arrester bracket comprises an iron tower body 1, wherein a lightning arrester 2 for attracting lightning is arranged on the top of the iron tower body 1, a lightning protection cable 4 connected to the ground is dragged on the iron tower body 1, and the lightning arrester 2 is used to guide lightning to the lightning protection cable 4, the lightning arrester 2 is arranged on the top of the iron tower body 1 through the lightning arrester bracket 3, the lightning arrester 2 is installed on the lightning arrester bracket 3 through a base 8, an insulating rubber block 15 is connected between the lightning arrester 2 and the base 8, and the base 8 is installed on the lightning arrester bracket 3 through a placement groove, such a setting can ensure that the current of lightning will not pass through the lightning arrester 2 directly to the iron tower body 1, but will be introduced into the lightning protection cable 4 from other ways to complete the derivation of lightning.

[0020] Reference Figure 2-Figure 4In this state, a plurality of rotating pressing frames 5 are rotatably arranged on the arrester bracket 3, the number of the plurality of rotating pressing frames 5 is three, and they are all buckled on the outer wall of the arrester 2, and the tops of the plurality of rotating pressing frames 5 are pressed with a same pressing platform 6 which is coaxially arranged with the arrester 2, wherein the rotating pressing frames 5 are arranged in a triangular cross and press against the arrester 2 under the action of the pressing platform 6, so as to complete the vertical stabilization of the arrester 2, wherein the rotating pressing frames 5 and the pressing platform 6 are made of insulating materials to prevent lightning from flowing out through other paths other than the conductive metal ring 7.

[0021] Reference Figure 5 and Figure 6 State, a first inner cavity 11 is provided in the lightning arrester bracket 3, and a first energized solenoid 13 is arranged in the first inner cavity 11, a first push plate 20 and a second push plate 21 are provided in the first inner cavity 11, a plurality of first energized solenoids 13 are provided in the iron tower body 1, wherein the number of the first energized solenoids 13 corresponds to the fastening bolts 9, the lightning arrester 2 is connected to the first energized solenoid 13 through a first wire 24, a conductive metal ring 7 is provided on the outer wall of the lightning arrester 2, and a connection point 10 for fixing the first wire 24 is also provided on the lightning arrester bracket 3, one end of the first wire 24 is connected to the conductive metal ring 7, and the other end of the first wire 24 is connected to the first energized solenoid 13, so that lightning will be introduced from the first wire 24 to one end of the first energized solenoid 13, and then flow out through the second wire 25, thereby generating a magnetic field in the first energized solenoid 13, and the second push plate 21 is made of metal iron, so it will attract the second push plate 21 to move toward the first energized solenoid 13.

[0022] A support rod 22 is connected between the first push plate 20 and the second push plate 21. The second push plate 21 is reset and retracted in the first inner cavity 11 by a reset spring 23. Therefore, when no current flows through the first energized solenoid 13, no magnetic field will appear. Then, the first push plate 20 is reset under the action of the reset spring 23. When current is generated, the first push plate 20 is pushed to move toward the fastening bolt 9.

[0023] The base 8 is fixed to the arrester bracket 3 by a plurality of fastening bolts 9. A bolt cavity 16 is provided at the bottom of the mounting groove. The fastening bolts 9 are inserted into the base 8 and fixed to the arrester bracket 3. Therefore, the fastening bolts 9 can fasten the base 8 and the arrester bracket 3.

[0024] The bolt cavity 16 is connected to the first inner cavity 11 through a transverse slot 17. A sliding plate 18 slides in the transverse slot 17. One end of the sliding plate 18 is connected to the first push plate 20. A plurality of protrusions 19 are provided on the sliding plate 18. The fastening bolt 9 passes through the base 8 and is inserted into the bolt cavity 16, and the protrusion 19 extends into the threaded groove of the fastening bolt 9. Since the outer side wall of the bolt cavity 16 does not have a threaded groove, the plurality of protrusions 19 on the sliding plate 18 in the transverse slot 17 cooperate with the fastening bolt 9 to play a bolt fitting role.

[0025] When thunderstorm occurs and is struck by lightning, the current will flow along the lightning arrester 2, the conductive metal ring 7, the first wire 24, the first energized solenoid 13, the second wire 25, the third wire 28 and then be derived from the lightning protection cable 4. In this process, the first energized solenoid 13 will be triggered to generate a magnetic field and attract the second push plate 21, pushing the sliding plug plate 18, so that the protrusion 19 will push the fastening bolt 9 to rotate, wherein the spiral of the fastening bolt 9 faces downward, thereby realizing the rotation and downward pressing of the fastening bolt 9, completing the fastening of the base 8 on the lightning arrester bracket 3.

[0026] Therefore, in thunderstorm weather, if struck by lightning, the base 8 originally placed in the lightning arrester bracket 3 will vibrate and shake violently, which will cause the base 8 with the lightning arrester 2 originally fastened by bolts to loosen, that is, the fastening bolts 9 originally fastened with bolts will loosen, but under the action of lightning, the original fastening bolts 9 will be driven to rotate downward, so the vibration and looseness caused by the lightning bombardment will be re-tightened, avoiding loosening caused by long-term use. At the same time, compared with the traditional fastening method, the disassembly method of this method is the same as the traditional disassembly method, and will not increase the difficulty of disassembly, and it is more convenient for high-altitude operation disassembly and replacement.

[0027] Reference Figure 7 and Figure 8 In this state, a second inner cavity 12 is opened on the lightning arrester bracket 3, and the second energized solenoid 14 is fixed in the second inner cavity 12 through the bracket 29. The second energized solenoid 14 is arranged in the iron tower body 1, and the first energized solenoid 13 is connected to the second energized solenoid 14 through the second wire 25. Multiple first energized solenoids 13 are connected to the second energized solenoid 14 through the second wire 25, so that current is introduced into the second inner cavity 12.

[0028] A connecting rod 26 is coaxially fixed on the second inner cavity 12, and a first relay 27 is provided on the connecting rod 26. The second wire 25 is connected to one end of the second energized solenoid 14 through the connecting rod 26. The function of the first relay 27 is to select and screen the size of the current. If the current is small, the first relay 27 cannot be triggered, and the current cannot flow to the second energized solenoid 14 through the connecting rod 26, so it will not trigger the opening of the second energized solenoid 14. The first relay 27 is a prior art and only plays a role in screening the current size in the present technical solution. If the current does not reach a certain value, it will not flow to the second energized solenoid 14, which will not be elaborated on here.

[0029] A third wire 28 is connected to the connecting rod 26 above the first relay 27, and the third wire 28 is connected to the lightning protection cable 4 through the second relay 34, wherein the first relay 27 and the second relay 34 have the same function, but the current triggered by the first relay 27 is greater than the current triggered by the second relay 34. Therefore, if a conventional lightning strike occurs, the current generated will flow from the third wire 28 through the second relay 34 and then out of the lightning protection cable 4, wherein the first relay 27 and the second relay 34 are both prior arts and will not be elaborated on herein.

[0030] A metal plate 30 is fixed at the bottom of the second energized solenoid 14, and the other end of the second energized solenoid 14 is connected to the metal plate 30. It should be noted that if the lightning strike is too strong and causes the third wire 28, the second relay 34 or the lightning protection cable 4 to operate under load, it is necessary to divert this part of the excessive current. When the first relay 27 is triggered to turn on, the second energized solenoid 14 will generate a magnetic field and attract the lifting plate 31 below to lift.

[0031] A lifting plate 31 for connecting the second energized solenoid 14 and the lightning protection auxiliary cable 33 is provided in the lightning arrester bracket 3. The lifting plate 31 is lifted vertically, so that the connecting side plate 32 and the lightning protection auxiliary cable 33 can connect the circuit during the lifting process. A plurality of lightning protection auxiliary cables 33 connected to the ground are provided on the lightning arrester bracket 3. One end of the plurality of lightning protection auxiliary cables 33 is arranged on the inner wall of the second inner cavity 12 and is located below the metal plate 30. A plurality of connecting side plates 32 are provided on the side wall of the lifting plate 31. The connecting side plates 32 and the lifting plate 31 are made of conductive metal material. In this way, during the process of the lifting plate 31 attracting and lifting, the current of the second energized solenoid 14 will flow through the metal plate 30, the lifting plate 31 and the connecting side plate 32 to the lightning protection auxiliary cable 33, and then this part of the excess current will flow from the lightning protection auxiliary cable 33 to the ground, and the excessive current will be derived from the lightning protection auxiliary cable 33, thereby completing the protection of the iron tower body 1 and the high-voltage wires.

[0032] A method for using a tower lightning arrester bracket, the specific operating steps are as follows: S1: First, the arrester 2 with the base 8 is installed on the arrester bracket 3, and then the fastening bolts 9 are inserted into the base 8 and fixed to the arrester bracket 3. Since the outer wall of the bolt cavity 16 does not have a thread groove, the multiple protrusions 19 on the sliding plate 18 in the transverse slot 17 cooperate with the fastening bolts 9 to play a bolt fitting role; S2: When thunderstorm occurs and lightning strikes, the current will flow along the arrester 2, the conductive metal ring 7, the first wire 24, the first energized solenoid 13, the second wire 25, the third wire 28 and then be led out from the lightning protection cable 4. In this process, the first energized solenoid 13 will be triggered to generate a magnetic field and attract the second push plate 21, pushing the sliding plug plate 18, so that the protrusion 19 will push the fastening bolt 9 to rotate, thereby realizing the rotation and downward pressing of the fastening bolt 9, completing the fastening of the base 8 on the arrester bracket 3; Therefore, in thunderstorm weather, if struck by lightning, the base 8 originally placed in the lightning arrester bracket 3 will vibrate and shake violently, which will cause the base 8 with the lightning arrester 2 originally fastened by bolts to loosen, that is, the fastening bolts 9 originally fastened with bolts will loosen, but under the action of lightning, the original fastening bolts 9 will be driven to rotate downward, so the vibration and looseness caused by the lightning bombardment will be re-tightened, avoiding loosening caused by long-term use. At the same time, compared with the traditional fastening method, the disassembly method of this method is the same as the traditional disassembly method, and will not increase the difficulty of disassembly, and it is more convenient for high-altitude operation disassembly and replacement.

[0033] S3: When the current is too large, or the lightning protection cable 4 is damaged and no longer connected to the ground, the current will pass through the first relay 27 and cause the second energized solenoid 14 to generate current, thereby attracting the lifting plate 31 to lift and allowing the connecting side plate 32 and the lifting plate 31 to connect to the lightning protection auxiliary cable 33 and the metal plate 30, and the excessive current will be discharged from the lightning protection auxiliary cable 33, thereby completing the protection of the iron tower body 1 and the high-voltage wires.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
