At this time, the compression bag will be squeezed by the wire of corresponding size to push the gas in the compression bag into the air cylinder, and push the two pneumatic piston rods and the third spring to move in opposite directions as a whole. At the same time, when the second hydraulic piston rod moves downward, the first clamping tooth plate can be pushed downward to engage with the top of the third spring for clamping and fixing, so that the compression bag as a whole can finally clamp and fix the wire stably and improve the sealing effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 11 As shown, the present invention provides a large through-flow module lightning arrester structure, including a lightning arrester shell 1; a through-flow module 2, which is movably connected to the middle part of the lightning arrester shell 1; a live wire interface 3, which is arranged at the top of the lightning arrester shell 1 and behind the through-flow module 2; a ground wire interface 4, which is arranged on the right side of the bottom end of the lightning arrester shell 1; a dustproof component 5 includes a limit rod 501, which is fixedly installed on the top of the lightning arrester shell 1 and on both sides of the through-flow module 2, and a movable frame 502 is movably sleeved on the surface of the limit rod 501, and a dustproof clamp block 503 located above the through-flow module 2 is arranged on the inner side of the movable frame 502, and a rubber clamp block 10 is arranged on the inner side of the dustproof clamp block 503, and the movable frame 502 is elastically connected to the top of the lightning arrester shell 1 through a first spring 504, and a disassembly component 6 located on the inner side of the movable frame 502 is arranged in the middle of the right side of the lightning arrester shell 1.

[0038] First, due to the elastic force of the two first springs 504, the two movable frames 502, the dustproof clamp block 503 and the rubber clamp block 10 can be smoothly pushed to slide toward each other in the horizontal direction along the surface of the limit rod 501, so that the positions of the live wire interface 3 and the ground wire interface 4 can be shielded and sealed to achieve the purpose of dust and moisture prevention.

[0039] like Figure 2 As shown, the disassembly assembly 6 includes an inclined panel 601, a mounting column 602 and a driving frame 603;

[0040] The inclined panel 601 is fixedly installed on the inner side of the right end of the movable frame 502 , the mounting column 602 is fixedly installed on the right side of the lightning arrester housing 1 and located on the inner side of the inclined panel 601 , and the driving frame 603 is movably sleeved on the surface of the mounting column 602 .

[0041] With the above solution, by providing a driving frame 603, when the operator pushes the driving frame 603 downward, the rollers on both sides will slide along the inclined groove inside the inclined panel 601 to squeeze the two mounting columns 602 and the movable frame 502 to move in opposite directions as a whole.

[0042] like Figure 5 and Figure 8 As shown, the interior of the lightning arrester housing 1 is provided with a locking assembly 7 located in the inner cavity of the movable frame 502 and the outer side of the limit rod 501, and the locking assembly 7 includes a first hydraulic cylinder 701, a first hydraulic piston cylinder 702, a locking block 703 and a card slot 704;

[0043] The first hydraulic cylinder 701 is fixedly installed inside the movable frame 502 and is located on the outside of the limit rod 501. The first hydraulic piston cylinder 702 is movably installed in the inner cavity of the first hydraulic cylinder 701. The locking block 703 is fixedly installed on the outer end of the first hydraulic piston cylinder 702. An inner groove movably installed on the surface of the locking block 703 is opened inside the lightning arrester housing 1. The slot 704 is opened inside the lightning arrester housing 1 and is located on both sides of the outer end of the limit rod 501.

[0044] The above solution is adopted: by providing a locking block 703, when hydraulic oil enters the inner cavity of the first hydraulic cylinder 701 and the hydraulic pressure increases, the two locking blocks 703 will be pushed to move away from each other and get stuck in the inner groove of the lightning arrester housing 1, thereby fixing the movable frame 502 as a whole.

[0045] like Figure 5 As shown, the size of the locking block 703 matches the size of the inner cavity of the slot 704 .

[0046] The above scheme is adopted: by providing a card slot 704, when the two movable frames 502 move away from each other and the two locking blocks 703 are stuck in the inner cavity of the card slot 704, the movable frames 502, the dustproof clamp block 503 and the rubber clamp block 10 will be moved away from each other as a whole to the outside of the live wire interface 3 and the ground wire interface 4 and fixed, so as to perform wiring processing on the position of the live wire interface 3 and the ground wire interface 4.

[0047] like Fig. 9 As shown, a hydraulic assembly 8 is disposed in the middle of the top of the movable frame 502, and the hydraulic assembly 8 includes a second hydraulic cylinder 801, a second hydraulic piston rod 802, a second spring 803 and an oil pipe 804;

[0048] The second hydraulic cylinder 801 is fixedly installed in the middle of the top of the movable frame 502, the second hydraulic piston rod 802 is movably installed in the inner cavity of the second hydraulic cylinder 801, the second spring 803 is fixedly installed on the top of the second hydraulic piston rod 802, and the oil pipe 804 is fixedly connected between the outer bottom of the second hydraulic cylinder 801 and the inner middle of the first hydraulic cylinder 701.

[0049] The above solution is adopted: by providing a second hydraulic piston rod 802, when the second hydraulic piston rod 802 is pushed downward as a whole, the hydraulic oil in the bottom inner cavity of the second hydraulic cylinder 801 will enter the inner cavity of the first hydraulic cylinder 701 through the oil pipe 804, so that the locking block 703 is smoothly pushed to move away from each other.

[0050] like Fig. 9 As shown, the top end of the second spring 803 is fixedly connected to the inner wall of the second hydraulic cylinder 801 .

[0051] The above solution is adopted: by providing the second spring 803, due to the elastic force of the second spring 803, the second hydraulic piston rod 802 can be smoothly pushed downward as a whole, so as to smoothly push away the hydraulic oil in the inner cavity at the bottom of the second hydraulic cylinder 801.

[0052] like Figure 8 and Fig. 9 As shown, a pull ring 9 is fixedly installed in the middle of the top end of the second hydraulic piston rod 802, and the number of the pull rings 9 is two.

[0053] The above scheme is adopted: by providing a pull ring 9, when the operator pulls the two pull rings 9 to drive the second hydraulic piston rod 802 to move upward as a whole, the gap at the bottom of the inner cavity of the second hydraulic cylinder 801 can be enlarged to generate negative pressure, thereby smoothly pumping out the hydraulic oil in the inner cavity of the first hydraulic cylinder 701 through the oil pipe 804.

[0054] like Figure 6 and Figure 7 As shown, a clamping assembly 11 is provided inside and outside the rubber clamping block 10, and the clamping assembly 11 includes a compression bag 1101, an air cylinder 1102, a pneumatic piston rod 1103, a tooth block 1104 and a third spring 1105;

[0055] The compression bag 1101 is fixedly installed in the inner cavity of the air cylinder 1102, the air cylinder 1102 is fixedly installed inside the dustproof clamp block 503 and is located on the outside of the compression bag 1101, the pneumatic piston rod 1103 is movably installed in the inner cavity of the air cylinder 1102, the gear block 1104 is fixedly installed at the outer end of the pneumatic piston rod 1103 and is located in the inner cavity of the movable frame 502, and the third spring 1105 is fixedly installed between the outer side of the inner end of the pneumatic piston rod 1103 and the inner cavity of the air cylinder 1102.

[0056] The above scheme is adopted: by providing a rubber clamp block 10 and a third spring 1105, due to the elastic force of the third spring 1105, the pneumatic piston rod 1103 and the tooth block 1104 can be pushed to reset toward each other as a whole. At the same time, due to the design of the rubber clamp block 10, it can be tightly attached to the surface of the wire after wiring, thereby improving the sealing effect of the live wire interface 3 or the ground wire interface 4 after wiring.

[0057] like Figure 7 , Fig.10 and Fig.11 As shown, a clamping assembly 12 is disposed inside the inner cavity of the movable frame 502, and the clamping assembly 12 includes a first clamping tooth plate 1201, a linkage plate 1202, and a second clamping tooth plate 1203;

[0058] The first clamping tooth plate 1201 is fixedly installed on the bottom end of the second hydraulic piston rod 802, the second clamping tooth plate 1203 is movably installed on the inner cavity of the lightning arrester housing 1 and the outside of the bottom dustproof clamp block 503, the linkage plate 1202 is movably sleeved on the inner cavity of the movable frame 502, and the upper and lower ends are slidably connected with the inner cavity of the first clamping tooth plate 1201 and one end of the second clamping tooth plate 1203.

[0059] The above solution is adopted: by providing a linkage plate 1202, when the first clamping tooth plate 1201 moves downward or upward as a whole, the second clamping tooth plate 1203 will be driven to move in the opposite direction through the linkage plate 1202.

[0060] like Figure 7 and Fig.11 As shown, the bottom of the first clamping tooth plate 1201 and the top of the second clamping tooth plate 1203 are both engaged with the outer end of the third spring 1105 .

[0061] By adopting the above scheme: when the first clamping tooth plate 1201 is downward as a whole, the linkage plate 1202 will drive the second clamping tooth plate 1203 upward, so that the bottom of the first clamping tooth plate 1201 and the top of the second clamping tooth plate 1203 are engaged with the outer end of the third spring 1105, and the third spring 1105 and the pneumatic piston rod 1103 are successfully fixed as a whole.

[0062] The working principle and use process of the present invention:

[0063] First, the elastic force of the two first springs 504 can push the movable frame 502, the rubber clamp block 10 and the clamping assembly 11 to move toward each other as a whole, so as to shield the positions of the live wire interface 3 and the ground wire interface 4 from dust. Then, when the operator needs to connect the positions of the live wire interface 3 and the ground wire interface 4, the pull ring 9 and the second hydraulic piston rod 802 can be pulled upward as a whole, so that the inner cavity at the bottom of the second hydraulic piston rod 802 generates negative pressure, thereby the hydraulic oil in the inner cavity of the first hydraulic cylinder 701 is drawn away through the oil pipe 804. At this time, the negative pressure will cause the two locking blocks 703 to move toward each other out of the inner groove of the lightning arrester housing 1, thereby releasing the fixation of the movable frame 502 as a whole. Push the driving frame 603 downward, so that the inclined plate 601 and the movable frame 502 are squeezed back to each other as a whole, until the locking block 703 is directly opposite to the card slot 704, and then the pull ring 9 can be loosened, so that the second hydraulic piston rod 802 is pushed downward by the second spring 803, so that the hydraulic oil in the bottom inner cavity of the second hydraulic cylinder 801 enters the inner cavity of the first hydraulic cylinder 701 and pushes the two first hydraulic piston cylinders 702 and the locking block 703 back to each other, so that the locking block 703 is stuck on the inner wall of the card slot 704, so that the movable frame 502, the dustproof clamp block 503 and the rubber clamp block 10 are moved to the outside as a whole and fixed, and then the wiring can be respectively connected through the positions of the live wire interface 3 and the ground wire interface 4;

[0064] When the wiring is completed, the pull ring 9 can be pulled upward, so that the hydraulic component 8 drives the locking block 703 to move toward each other and disengage from the slot 704 until the locking block 703 is directly opposite to the inner slot at the top of the lightning arrester housing 1. At this time, the pull ring 9 is released, so that the elastic force of the second spring 803 is released and the second hydraulic piston rod 802 is pushed downward as a whole, so that the hydraulic oil in the bottom inner cavity of the second hydraulic cylinder 801 is pushed to the inner cavity of the first hydraulic cylinder 701 through the oil pipe 804, and the two locking blocks 703 are pushed back to back to be stuck in the inner slot at the top of the lightning arrester housing 1, so that the movable frame 502 is firmly fixed as a whole facing each other.

[0065] Note: When the live wire interface 3 and the ground wire interface 4 are connected to wires respectively, the current generated by external lightning can be received through the live wire, and then guided to flow into the earth through the ground wire, thereby achieving the purpose of lightning protection.

[0066] At the same time, after the dustproof clamp block 503, the rubber clamp block 10 and the compression bag 1101 clamp the wire towards each other, the compression bag 1101 on the inner wall of the rubber clamp block 10 will be squeezed and deformed by the wire, so that the gas in the compression bag 1101 enters the inner cavity of the air cylinder 1102, so that the air pressure pushes the two pneumatic piston rods 1103 and the third spring 1105 to move in opposite directions. When the pull ring 9 is released to make the second spring 803 push the second hydraulic piston rod 802 downward as a whole, the first clamping tooth plate 1201 will move downward synchronously, and then the linkage plate 1202 will rotate to link the second clamping tooth plate 1 203 moves upward, so that the bottom of the first clamping tooth plate 1201 at the top is engaged and clamped with the top of the third spring 1105 above, and the top of the second clamping tooth plate 1203 is engaged and clamped with the bottom end of the third spring 1105 at the bottom, so that the compression bag 1101 finally follows the size of the wire to deform and fit synchronously, and due to the plastic design of the rubber clamp block 10, it can smoothly fit and clamp with the surface of the wire, so as to shield and seal the position of the live wire interface 3 and the ground wire interface 4, avoid dust and moisture from entering and causing short circuit of electronic components, and achieve the purpose of good sealing, dustproof and moisture-proof.
