Description
Technical Field
[0001] This utility model relates to the field of power protection technology, and in particular to a drop-out lightning protection device. Background Technology
[0002] The drop-out surge protector is a new type of lightning protection device that integrates overvoltage protection and fault indication functions. It is widely used in 10kV distribution lines and distribution transformers. Under normal conditions, when lightning overvoltage or switching overvoltage occurs, it can discharge a huge current into the ground to protect the power equipment. Under fault conditions, that is, under drop-out conditions, the surge protector frame is disconnected from the high-voltage line, forming a clear disconnection point, and at the same time, a fault signal is emitted.
[0003] In existing drop-out surge protection devices, the internal surge protection frame lacks effective protection and real-time status monitoring, making it susceptible to swaying and displacement due to external environmental influences. Operators cannot monitor the device's status in real time. Furthermore, when installing the device in a circuit system, the position of the surge protection frame cannot be flexibly adjusted according to the line location, resulting in complex and cumbersome installation and inconvenient maintenance.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0047] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0049] like Figures 1 to 4 As shown, this utility model provides a drop-out lightning protection device, including a base 1, a lightning protection structure 2, and an adjustment structure 3. The base 1 is mounted on a support foundation. The lightning protection structure 2 includes a lightning protection frame 21 and two support blocks 22. The lightning protection frame 21 is vertically adjustable on the base 1, and the two support blocks 22 are located on either side of the lightning protection frame 21. The lightning protection frame 21 is connected to the circuit system. The adjustment structure 3 includes a drive mechanism 31, a threaded rod 32, and a smooth rod 33. The drive mechanism 31 is mounted on the base 1. Both the threaded rod 32 and the smooth rod 33 extend vertically and are located on either side of the lightning protection frame 21. One support block 22 is fitted and threaded onto the threaded rod 32, while the other support block 22 is slidably fitted onto the smooth rod 33. Driven by the drive mechanism 31, the lightning protection frame 21 can move vertically to adaptively adjust its position according to the line location, facilitating installation and subsequent maintenance.
[0050] Specifically, the drive mechanism 31 is a motor commonly used in this field. The base is equipped with grounding support legs, which firmly support the base on the support foundation and ensure a good connection with the earth, enabling the device to conduct lightning into the earth, achieving effective lightning protection grounding and ensuring the safety of the device and its surrounding environment. The aforementioned support foundation can be the ground or a support frame at a higher location.
[0051] like Figure 2 As shown, a through hole 212 is provided on one side of the lightning protection frame 21. The through hole 212 is used to allow lines to pass through, terminals to be installed, or to connect to the lines on the distribution transformer side.
[0052] Furthermore, the adjustment structure 3 also includes an elastic element 35, which extends vertically and is connected between the base 1 and the lightning protection frame 21.
[0053] For example, in this embodiment, the elastic element 35 is a spring, and two springs are provided. In other embodiments, the number of elastic elements 35 can be set as needed, and no specific limitation is made here.
[0054] Optionally, a flexible member 211 is provided on the bottom side of the lightning protection frame 21. When the lightning protection frame 21 moves up and down or is impacted by external forces, the flexible member 211 can act as a buffer to reduce the impact of external forces on the lightning protection frame 21. For example, the flexible member 211 is a rubber sheet.
[0055] The cooperation between the elastic element 35 and the flexible element 211 can effectively buffer the vibration of the lightning protection frame 21, ensure the stability of the lightning protection frame 21, and prevent hard impacts from damaging the components inside the lightning protection frame 21. In addition, it should be noted that the elastic deformation range of the elastic element 35 is limited and will not restrict the "fall" of the lightning protection frame 21 during use.
[0056] Optionally, the adjustment structure 3 also includes a button 36, which is connected to the drive mechanism 31. Pressing the button 36 can start and stop the drive mechanism 31, thereby adjusting the position of the lightning protection frame 21 vertically. The operation is simple and convenient.
[0057] Optionally, such as Figure 1 and Figure 2 As shown, the device also includes a shielding structure 4, which comprises a fixing frame 41, a first plate 42, a second plate 43, and a limiting rod 44. The fixing frame 41 is mounted on the base 1, and the first plate 42 is mounted on the fixing frame 41 and spaced above the lightning protection frame 21. The first plate 42 has a sliding groove 421, and the second plate 43 is slidably mounted in the sliding groove 421 in a horizontal direction. The limiting rod 44 passes through the second plate 43, and its two ends extending out of the second plate 43 are respectively engaged with the two side walls of the sliding groove 421 to limit the relative position of the second plate 43 and the first plate 42. This configuration allows for adaptive adjustment of the position of the second plate 43 relative to the first plate 42 according to actual needs, thereby adjusting the shielding range. This makes the device more flexible and better protects the components inside from external influences.
[0058] Specifically, such as Figure 2 As shown, the second plate 43 is provided with an operating part 431. The operating part 431 facilitates the movement of the second plate 43 by the operator, making the operation more convenient and efficient. Exemplarily, in this embodiment, the operating part 431 is a handle; in other embodiments, the operating part 431 may also be a protrusion, as long as it facilitates the movement of the second plate 43 by the operator.
[0059] Furthermore, multiple limiting holes 422 are spaced apart on both sides of the slide 421. The end of the limiting rod 44 that protrudes from the second plate 43 can be selectively inserted into any of the limiting holes 422. That is, by moving the second plate 43 and adjusting its position relative to the first plate 42, the limiting rod 44 is then sequentially inserted through the limiting holes 422, the second plate 43, and the limiting holes 422 on the opposite side to limit the first plate 42 and the second plate 43, thereby improving the stability of the second plate 43 and ensuring the blocking effect.
[0060] Furthermore, the shielding structure 4 also includes two locking members 45, which are screwed onto the two ends of the limiting rod 44 in a corresponding manner and abut against the outer wall of the first plate 42. After the limiting rod 44 is installed in place, the locking members 45 are screwed on to prevent the limiting rod 44 from moving along its own axis, thereby further improving the stability of the second plate 43.
[0061] In this specific embodiment, the outer peripheral wall of the limiting rod 44 is provided with threads, and the locking part 45 is a nut. The locking part 45 can be screwed on without the aid of any external tools, making the operation simple and quick, and the screwing has good stability.
[0062] Optionally, the outer peripheral walls of both the first plate 42 and the second plate 43 are coated with a nano self-cleaning layer. This nano self-cleaning layer utilizes the properties of nanomaterials to give the surfaces of the first plate 42 and the second plate 43 hydrophobic, oleophobic, and stain-resistant capabilities. When dust or rainwater falls on the surface of the plates, it will automatically slide off under its own weight or wind force, thus keeping the surface clean and reducing the probability of manual cleaning and maintenance. Specifically, the nano self-cleaning layer is a coating already disclosed in the prior art, and its specific composition and principle are as described in the prior art, and will not be elaborated here.
[0063] Optionally, the device further includes a monitoring structure 5, which includes a status sensor 51, a processor 52, and a wireless communication device 53. The status sensor 51 is disposed on the lightning protection frame 21 and is used to monitor the status of the lightning protection frame 21. Figure 3 As shown, both the processor 52 and the wireless communication device 53 are mounted on the base 1. The processor 52 is connected between the status sensor 51 and the wireless communication device 53. The status signal monitored by the status sensor 51 is transmitted to the processor 52, which processes it and then sends it to the wireless communication device 53. The wireless communication device 53 then remotely transmits the status signal to the mobile terminal, so that operators can monitor the specific status of the device in real time.
[0064] Specifically, the status sensor 51, processor 52 and wireless communication device 53 are all existing conventional devices, and their specific structures and principles are based on existing technologies and will not be described in detail here.
[0065] More specifically, in this embodiment, an insulating box 13 is provided on the base 1, and the insulating box 13 is disposed on the base 1 and covers the outside of the lightning protection frame 21. When the device is not connected to the circuit system, the insulating box 13 covers the base 1 to protect the components on the base 1. A top cover 14 is provided at the upper end of the insulating box 13, which can close the top of the insulating box 13 to prevent dust, rainwater, etc. from entering the box. In addition, a handle 15 is provided on the outside of the insulating box 13 to facilitate the operation and movement of the device by the operator, thereby improving the portability of the device. When the device is connected to the circuit system, the insulating box 13 must be removed.
[0066] Furthermore, the adjustment structure 3 also includes a fine-tuning component 34, such as... Figure 4 As shown, the fine-tuning component 34 includes a vibration sensor, an adjustment mechanism 341, and a rotating shaft 342. The vibration sensor is mounted on the support block 22 and connected to the processor 52. The vibration sensor is used to monitor whether the lightning protection frame 21 vibrates. The adjustment mechanism 341 is mounted on the support block 22 and connected to the processor 52. The rotating shaft 342 is located between the support block 22 and the lightning protection frame 21 and is rotatably connected to the output end of the adjustment mechanism 341. When the vibration sensor detects that the lightning protection frame 21 has moved or vibrated, the vibration sensor transmits the vibration signal to the processor 52. The processor 52 controls the start and stop of the adjustment mechanism 341, so as to drive the rotation of the rotating shaft 342 through the adjustment mechanism 341 to adjust the position of the lightning protection frame 21, thereby counteracting external movement and vibration and ensuring the stable state of the lightning protection frame 21.
[0067] Specifically, the support block 22 has a receiving groove, and the adjustment mechanism 341 and the rotating shaft 342 are both disposed in the receiving groove. On the one hand, the space can be fully utilized and the space utilization rate can be improved; on the other hand, the setting of the receiving groove can provide a certain degree of protection for the adjustment mechanism 341 and the rotating shaft 342. For example, the adjustment mechanism 341 is a DC motor.
[0068] In addition, the lightning protection frame 21 has a normal state and a fault state. In the normal state, the rotating shaft 342 is locked at the output end of the adjusting mechanism 341 to ensure the stability of the lightning protection frame 21 and its conductive connection with the circuit system. In the fault state, if a lightning strike causes a sudden increase in current in the circuit system, the processor 52 will send an unlocking signal to the adjusting mechanism 341. The output end of the adjusting mechanism 3 will be unlocked from the rotating shaft 342, and the lightning protection frame 21 will flip around the axis of the rotating shaft 342, in a "falling" shape, so that the operators can find the fault location in time.
[0069] Optionally, such as Figure 2As shown, a storage slot 11 is provided on the base 1, and a cover plate 12 is rotatably mounted on the opening of the storage slot 11. The storage slot 11 has a closed state and an open state. In the closed state, the cover plate 12 blocks and locks the opening of the storage slot 11. In the open state, the cover plate 12 is detached from the opening of the storage slot 11. With the above configuration, the storage slot 11 can be used to store accessories, tools, or testing equipment related to the device, providing a convenient storage space for items, making it easy for operators to access relevant tools when maintaining and repairing the device. The cover plate 12 can seal the opening of the storage slot 11 to ensure the cleanliness and safety of the stored items.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
