[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] This utility model provides the following technical solution: As attached Figure 1-4As shown, a waterproof surge arrester includes a housing 1 and a connecting mechanism 2. The housing 1 has a receiving groove 3 and a discharge groove 4, with the discharge groove 4 adjacent to the receiving groove 3. A connecting hole 5 is formed on the groove wall of the receiving groove 3, and a receiving hole 6 is formed on the groove wall of the discharge groove 4 corresponding to the connecting hole 5. A connecting channel 7 connects the connecting hole 5 and the receiving hole 6. One end of the connecting mechanism 2 is placed in the receiving groove 3 through the connecting channel 7, and the other end of the connecting mechanism 2 is placed in the discharge groove 4. The housing 1 also has a waterproof structure 8, which includes an inner waterproof structure 9, an outer waterproof structure 10, and a control component 11. The control component 11 is movably mounted on the housing 1. The control component 11 has an annular connecting portion 12 and a transmission drainage portion 13. At least two transmission drainage portions 13 are provided, evenly spaced on the inner ring side of the annular connecting portion 12 and extending into the housing 1 towards the junction groove 3. An outer waterproof structure 10 is retractably mounted on the annular connecting portion 12, and an inner waterproof structure 9 is retractably mounted within the junction groove 3. One end of the transmission drainage portion 13 extending into the junction groove 3 is connected to the inner waterproof structure 9. During the movement of the control component 11, the inner waterproof structure 9 and the outer waterproof structure 10 extend and retract, thereby achieving waterproofing and drainage. In this embodiment, the waterproof structure 8 further enhances the waterproof performance of the surge arrester. By moving the control component 11, the inner waterproof structure 9 and the outer waterproof structure 10 can be simultaneously driven to extend and retract, thus achieving comprehensive waterproof protection for the surge arrester. The design of the control component 11 further optimizes the performance and ease of operation of the waterproof surge arrester. The annular connecting portion 12, serving as the basic structure of the control component 11, not only provides stable support but also ensures the correct installation and positioning of the transmission drainage portion 13 and the external waterproof structure 10. The transmission drainage portions 13 are evenly spaced on the inner ring side of the annular connecting portion 12 and extend into the housing 1 towards the junction box 3. This layout ensures the uniformity and efficiency of the drainage action. During the movement of the control component 11, the transmission drainage portion 13 can precisely drive the internal drainage structure to extend and retract, thereby effectively draining water stains from the junction box 3. Simultaneously, the external waterproof structure 10 is extendable and retractable on the annular connecting portion 12, allowing for flexible adjustment as the control component 11 moves, further enhancing the waterproof performance of the surge arrester. In this embodiment, the size of the waterproof structure 8 can be adjusted according to the actual connection dimensions between the surge arrester and the plug, and specific circumstances.

[0018] Furthermore, the external waterproof structure 10 includes a waterproof corrugated pipe 14 and a connecting rod 15. The waterproof corrugated pipe 14 is sleeved on the outside of the housing 1, with one end fixedly connected to the housing 1 and the other end connected to the connecting rod 15. The connecting rod 15 is connected to the annular connecting portion 12 of the control component 11. During the movement of the control component 11, the waterproof corrugated pipe 14 expands and contracts via the connecting rod 15 to achieve waterproofing. In this embodiment, the design of the external waterproof structure 10 further optimizes the waterproofing effect of the surge arrester. The waterproof corrugated pipe 14, as its core component, not only has good elasticity and sealing performance, effectively preventing moisture from seeping in from the outside of the housing 1, but also can flexibly expand and contract with the movement of the control component 11, thereby achieving comprehensive waterproof protection for the outside of the surge arrester. The connecting rod 15 is firmly connected to the annular connecting portion 12 of the control component 11, ensuring the stability and reliability of the external waterproof structure 10 during movement. Even in severe weather conditions such as strong winds and heavy rain, the external waterproof structure 10 can effectively block moisture and ensure the normal operation of the surge arrester when it is in operation.

[0019] Furthermore, the internal waterproof structure 9 is a drainage corrugated pipe 16. A drainage cavity 17 is formed inside the housing 1, and the drainage corrugated pipe 16 is disposed inside the drainage cavity 17. One end of the drainage corrugated pipe 16 is fixedly connected to the side wall of the drainage cavity 17. Several interconnected drainage channels 18 are also provided between the drainage cavity 17 and the electrical connection slot 3. A moving channel 19 is also provided inside the housing 1. The transmission drainage part 13 of the control component 11 passes through the moving channel 19 and connects to the drainage corrugated pipe 16. In this embodiment, the function of the internal waterproof structure 9 is to promptly drain water stains from the electrical connection slot 3, preventing water from damaging the electrical connection part. As the core component of the internal waterproof structure 9, the drainage corrugated pipe 16 has good elasticity and resilience, and can extend and retract under the drive of the control component 11, thereby compressing and discharging the air in the drainage cavity 17. When the control component 11 moves, the transmission drainage part 13 will precisely drive the drainage corrugated pipe 16 to contract, smoothly discharging the air in the drainage cavity 17 through the drainage channel 18. During the exhaust process, this air enters the junction box 3, carrying away any water stains within it, thus achieving effective waterproof protection for the junction box 3. Simultaneously, the drainage channel 18 ensures that air can flow smoothly out under the pressure of the drainage chamber 17, providing sufficient drainage force for the inner waterproof structure 9. This design not only improves the waterproof performance of the surge arrester but also guarantees its stability and reliability during use.

[0020] Furthermore, a movable platform 20 is provided at the position of the housing 1 corresponding to the transmission drainage section 13, and the movable platform 20 limits the movement of the transmission drainage section 13. In this embodiment, the function of the movable platform 20 is to precisely guide and limit the movement of the transmission drainage section 13, ensuring its stability and accuracy during movement. The design of the movable platform 20 takes into account the shape of the transmission drainage section 13, achieving effective support and limitation for the transmission drainage section 13. During the movement of the control component 11, the transmission drainage section 13 moves along the trajectory of the movable platform 20, thereby ensuring the uniformity and efficiency of the drainage action. At the same time, the setting of the movable platform 20 also improves the stability and durability of the surge arrester during the drainage process. This design not only further optimizes the performance of the waterproof surge arrester, but also ensures its reliability during use.

[0021] Furthermore, a connecting platform 21 is provided on the outer side of the connecting hole 5. The connecting platform 21 has a hollow structure and extends from the side near the discharge tank 4 towards the opening of the receiving tank 3. In this embodiment, the connecting platform 21 guides and controls the airflow direction within the drainage channel 18. The hollow structure design of the connecting platform 21 not only provides a smooth flow path for the air but also avoids turbulence or backflow during the airflow process. This design ensures that the air in the drainage channel 18 can be smoothly discharged along the set path, thereby effectively carrying away the water stains in the receiving tank 3. At the same time, the extension of the connecting platform 21 from the side near the discharge tank 4 towards the opening of the receiving tank 3 allows the air to gradually move away from the discharge tank 4 during the discharge process, avoiding the risk of water stains being re-inhaled into the discharge tank 4.

[0022] Furthermore, the connecting platform 21 is closely fitted to the connecting mechanism 2. In this embodiment, the close fit between the connecting platform 21 and the connecting mechanism 2 ensures that water stains cannot flow into the discharge tank 4 through the junction groove 3, thereby further improving the safety and reliability of the waterproof surge arrester. The tight fit between the connecting platform 21 and the connecting mechanism 2 not only enhances the overall sealing of the structure but also avoids electrical connection failures caused by water penetration. This design ensures that the surge arrester maintains stable electrical performance under various harsh environments, effectively protecting electrical equipment and personal safety. At the same time, the close fit between the connecting platform 21 and the connecting mechanism 2 prevents component loosening or damage caused by water erosion, extending the service life of the surge arrester.

[0023] Furthermore, the connection mechanism 2 includes a receiving terminal 22 and a discharging terminal 23. The receiving terminal 22 and the discharging terminal 23 are perpendicularly connected. One end of the receiving terminal 22 passes through the connecting hole 5 and is disposed in the receiving groove 3, while the other end of the receiving terminal 22 intersects with the discharging terminal 23 in the discharging groove 4. In this embodiment, the function of the receiving terminal 22 and the discharging terminal 23 is to realize the electrical connection of the surge arrester. The receiving terminal 22 is responsible for receiving external current and is connected to the receiving terminal 22 in the receiving groove 3 through the connecting hole 5. The discharging terminal 23 is perpendicularly connected to the receiving terminal 22 and is located in the discharging groove 4, used to safely conduct the current inside the surge arrester to the ground, thereby protecting electrical equipment and personal safety. The perpendicular connection design of the receiving terminal 22 and the discharging terminal 23 not only ensures the stability and reliability of the electrical connection, but also makes the surge arrester more compact in structure, facilitating installation and use. Meanwhile, this design also takes into account the heat dissipation problem of the surge arrester during operation. Through reasonable layout, the heat dissipation efficiency of the surge arrester is improved and its service life is extended.
