Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an electrical equipment protection device with a lightning protection structure. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. The important role that electricity plays in our lives and production cannot be ignored. It brings us great convenience and has become an important energy source in our production and life. The most critical factor in power plants that enables the normal operation and transmission of electricity is electrical equipment.

[0003] Currently, most existing electrical equipment protection devices with lightning protection structures involve installing lightning rods on the top of the electrical equipment enclosure. However, lightning rods do not have a storage function, and in severe weather conditions, such as hail, the lightning rods are easily damaged by hail impacts, thus reducing their lightning protection effectiveness.

[0004] Therefore, the existing lightning protection devices for electrical equipment, which mostly involve installing lightning rods on the top of the electrical equipment enclosure, are problematic because these rods lack a retractable design. In severe weather conditions, such as hail, the lightning rods are easily damaged by hail impacts, leading to reduced lightning protection effectiveness. A new lightning protection device can be designed, incorporating a motor, threaded rod, moving block, connecting rod, lifting plate, lightning rod body, protective box, electric actuator, and top cover. Starting the motor drives the threaded rod to rotate, which in turn moves the lightning rod body up and down on the lifting plate via the connecting rod. Activating the electric actuator then drives the top cover to move back and forth via the connecting plate. In the event of hail, the motor retracts the lightning rod body into the protective box, and the electric actuator drives the top cover to shield the top of the protective box. In this scenario, the protective box and top cover effectively protect the lightning rod body. Utility Model Content

[0005] To overcome the current problem that most existing lightning protection devices for electrical equipment consist of installing lightning rods on the top of the electrical equipment enclosure, but these lightning rods lack a storage function, and are easily damaged by hail in severe weather, such as hail, thus reducing their lightning protection effectiveness.

The moving block can then drive the lifting plate to move up and down via the connecting rod. The lifting plate can then drive the lightning rod body to move up and down. In thunderstorms, the motor is started to adjust the lightning rod body to the upper end of the rainproof eaves, at which point the lightning rod body can play a role in lightning protection. In hail, the motor is started to adjust the lightning rod body into the protective box, and the electric actuator is activated. The output end of the electric actuator can drive the connecting plate and the top cover to move forward. The top cover can then cover the top of the protective box, thus protecting the lightning rod body.

[0008] Preferably, the top of the rainproof eaves has a through hole that communicates with the mounting groove.

[0009] Preferably, the top of the protective box is connected to four limiting rods, and the other end of the four limiting rods passes through the lifting plate and is connected to the bottom of the rainproof eaves.

The moving blocks on the front and rear sides are acted upon by the thread of the threaded rod, thereby driving the lightning rod body on the lifting plate to move up and down through the connecting rod. When it is necessary to protect the lightning rod body in hail weather, starting the motor adjusts the lightning rod body into the protective box. Starting the electric push rod allows the output end of the electric push rod to drive the top cover to move forward through the connecting plate. The top cover can then shield the top of the protective box, thereby protecting the lightning rod body and preventing damage to it. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4This utility model provides an embodiment of an electrical equipment protection device with a lightning protection structure, including a protective box 1; support rods 2 are connected to the four corners of the top of the protective box 1, and rainproof eaves 3 are connected to the top of the support rods 2; a partition 5 is connected to the upper inside of the support rods 2, and a side plate 4 is connected to the front side of the partition 5; a motor 6 is installed on the back of the protective box 1, and a threaded rod 7 is connected to the output end of the motor 6; the other end of the threaded rod 7 is installed on the back of the side plate 4 through a bearing; movable blocks 8 are threaded to the outer sides of the threads on the front and rear sides of the threaded rod 7; a through groove 9 is opened on the top of the protective box 1; a connecting rod 10 is hinged to the top of the movable block 8; a lifting plate 11 is hinged to the other end of the connecting rod 10 through the through groove 9; an installation groove 12 is opened on the top of the lifting plate 11; a lightning rod body 14 is installed at the bottom inside the installation groove 12; a protective box 16 is connected to the top of the rainproof eaves 3; and an electric push rod 17 is installed on the right side inside the protective box 16. The output end of the electric actuator 17 is connected to a connecting plate 18, and the top of the connecting plate 18 is connected to a top cover 19. When the motor 6 is started, the output end of the motor 6 can drive the threaded rod 7 to rotate. The moving block 8 is acted upon by the thread of the threaded rod 7, thus moving inward or outward simultaneously. The moving block 8 can then drive the lifting plate 11 to move up and down via the connecting rod 10. The lifting plate 11 can then drive the lightning rod body 14 to move up and down. In thunderstorms, the starting motor 6 adjusts the lightning rod body 14 to the upper end of the rainproof eaves 3, at which time the lightning rod body 14 can play the role of lightning protection. In hail, the starting motor 6 adjusts the lightning rod body 14 into the protective box 16. The electric actuator 17 is started, and the output end of the electric actuator 17 can drive the connecting plate 18 and the top cover 19 to move forward. The top cover 19 can then cover the top of the protective box 16, thus providing protection for the lightning rod body 14.

[0024] Therefore, in practical implementation, motor 6 uses a stepper motor or servo motor to ensure precise control of the rotation angle and speed of the threaded rod 7. The threaded rod 7 is designed with a double-threaded design, and the thread directions on its front and rear sides are opposite. This way, when motor 6 drives the threaded rod 7 to rotate, the two moving blocks 8 can move simultaneously but in opposite directions along the threaded rod 7—one moving inwards and the other outwards, or simultaneously moving towards the middle or both ends, depending on the rotation direction of the threaded rod 7. This design ensures that the lifting plate 11 can rise and fall smoothly, avoiding tilting or jamming caused by unilateral force. The connecting rod 10 is hinged at both ends; one end is hinged to the moving block 8, and the other end is hinged to the lifting plate 11 through the through slot 9. This design not only allows the lifting plate 11 to rise and fall freely in the vertical direction but also absorbs and disperses lateral forces generated by wind or external impacts to a certain extent, enhancing the stability and durability of the structure. The lightning rod body 14 is made of a material with good electrical conductivity (such as copper or aluminum) and is firmly installed in the mounting slot 12 of the lifting plate 11, ensuring a good electrical connection. An insulating layer can be installed at the bottom of the mounting slot 12 to prevent direct contact between the lightning rod and the protective box 1, reducing the risk of unintended current conduction. Simultaneously, the lightning rod body 14 is regularly inspected and maintained to ensure its surface is free of rust and damage, maintaining good conductivity. The electric actuator 17 is selected with sufficient thrust and stability to ensure that the top cover 19 can be quickly and reliably pushed onto the protective box 16 in severe weather conditions such as hail, forming an effective protective barrier. The top cover 19 is designed with impact-resistant materials, such as thickened fiberglass or stainless steel, to withstand hail impacts. Furthermore, a sealing strip can be installed between the top cover 19 and the protective box 16 to improve waterproof and dustproof performance.

[0025] Please see Figures 1-5 In this embodiment, the top of the rainproof eaves 3 has a through hole 13, which communicates with the mounting groove 12. The top of the protective box 1 is connected to four limiting rods 22, the other ends of which pass through the lifting plate 11 and are connected to the bottom of the rainproof eaves 3. A drainage groove 15 is provided on the rear side of the lifting plate 11, which passes through the lifting plate 11 and communicates with the mounting groove 12. Sliding grooves 21 are provided on both the left and right sides of the protective box 16, and sliders are connected to the bottom left and right sides of the top cover 19. 20. The other end of the slider 20 is located inside the slide groove 21. The opening of the through hole 13 can make way for the lightning rod body 14, thereby facilitating the raising and lowering of the lightning rod body 14. The opening of the drainage groove 15 facilitates the discharge of rainwater. The setting of the limit rod 22 can limit the lifting plate 11, thereby ensuring the stability of the lifting plate 11. The setting of the slide groove 21 and the slider 20 can limit the top cover 19, thereby ensuring the stability of the movement of the top cover 19.

[0026] The through-hole 13 is precisely positioned to correspond to the lifting path of the lightning rod body 14, ensuring that the lightning rod body 14 is not obstructed during lifting. The edges of the through-hole 13 should be rounded to avoid friction or scratches during the lifting of the lightning rod body 14. Furthermore, the size of the through-hole 13 should be slightly larger than the diameter of the lightning rod body 14 to allow for an appropriate clearance, facilitating the passage of the lightning rod body 14 while preventing jamming due to thermal expansion and contraction or slight deviations. The limiting rod 22 is made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel, to ensure its long-term stability. The connection between the limiting rod 22 and the lifting plate 11 should be a sliding fit, meaning that the lifting plate 11 has holes matching the diameter of the limiting rod 22, and wear-resistant sleeves can be installed inside the holes to reduce friction. This design not only restricts the horizontal movement of the lifting plate 11 but also ensures the stability and verticality of the lifting plate 11 during lifting through the combined action of the four limiting rods 22. The design of the drainage channel 15 should consider the rapid discharge of rainwater and the prevention of water accumulation. The bottom of the drainage channel 15 can be set as an inclined surface to guide rainwater to one side or the center and discharge it through a pre-set drain outlet. At the same time, the interconnection design between the drainage channel 15 and the mounting groove 12 not only facilitates the discharge of rainwater, but also provides additional cooling for the lightning rod body 14 when necessary, reducing the heat generated by lightning strikes. The slide 21 should be designed as a dovetail groove or T-shaped groove with a self-locking function to ensure that the top cover 19 will not fall off during movement. The fit between the slider 20 and the slide 21 should be tight and smooth. A layer of low-friction lubricant, such as graphite or polytetrafluoroethylene, can be applied to the surface of the slider 20 to reduce frictional resistance. In addition, a buffer pad can be set at the end of the slide 21 to absorb the impact force when the top cover 19 moves into place, preventing noise or damage. Considering that the electrical equipment protection device may be exposed to the outdoor environment for a long time, its waterproof and dustproof performance should be emphasized. In addition to the design of the drainage channel 15, waterproof rubber rings or dust covers can be installed at the openings such as the through hole 13 and the slide 21 to prevent rainwater and dust from entering. At the same time, the joints of components such as the protective box 1, the rainproof eaves 3, and the protective box 16 should also be sealed to ensure the airtightness of the entire device.

[0027] Please see Figure 1 In this embodiment, the protective box 1 has a cabinet door 23 on the front and a support block 24 connected to the bottom of the protective box 1. There are four support blocks 24, which are respectively located at the four corners of the bottom of the protective box 1. The cabinet door 23 makes it easy for personnel to open the protective box 1, thereby facilitating the installation of electrical equipment. The support blocks 24 provide support for the protective box 1.

[0028] When in operation, the motor 6 is started, and the output end of the motor 6 drives the threaded rod 7 to rotate. The moving block 8 is acted upon by the thread of the threaded rod 7, and can move inward or outward simultaneously. The moving block 8 can then drive the lifting plate 11 to move up and down through the connecting rod 10. The lifting plate 11 can then drive the lightning rod body 14 to move up and down. In thunderstorms, the motor 6 is started to adjust the lightning rod body 14 to the upper end of the rainproof eaves 3. At this time, the lightning rod body 14 can play the role of lightning protection. In hail, the motor 6 is started to adjust the lightning rod body 14 into the protective box 16. The electric push rod 17 is started, and the output end of the electric push rod 17 can drive the connecting plate 18 and the top cover 19 to move forward. The top cover 19 can then cover the top of the protective box 16. At this time, the protective box 16 and the top cover 19 can then protect the lightning rod body 14. During thunderstorms, rainwater can flow through the through hole 13 and the mounting groove 12 to the drainage groove 15 for discharge.

[0029] Through the above steps, by setting up motor 6, threaded rod 7, moving block 8, connecting rod 10, lifting plate 11, lightning rod body 14, protective box 16, electric push rod 17, and top cover 19, starting motor 6 drives threaded rod 7 to rotate. Moving block 8 can then drive lightning rod body 14 on lifting plate 11 to move up and down via connecting rod 10. Starting electric push rod 17 can then drive top cover 19 to move back and forth via connecting plate 18. In the event of hail, starting motor 6 will retract lightning rod body 14. Returning to the interior of the protective box 16, the electric actuator 17 is activated to drive the top cover 19 to shield the top of the protective box 16. At this time, the protective box 16 and the top cover 19 can protect the lightning rod body 14, thus solving the problem that most existing electrical equipment protection devices with lightning protection structures install lightning rods on the top of the electrical equipment box for lightning protection. However, the lightning rod does not have a storage function. In some severe weather, such as hail, the lightning rod is easily damaged by hail impact, resulting in a reduction in lightning protection effect.

[0030] In practical implementation, the cabinet door 23 should be made of corrosion-resistant and weather-resistant materials, such as stainless steel or galvanized steel sheet, to ensure long-term stability and durability. A sealing strip, such as a rubber or silicone sealing strip, should be installed at the connection between the cabinet door 23 and the protective box 1 to prevent rainwater, dust, and other impurities from entering the protective box 1 and protecting the internal electrical equipment. A lock, such as a mechanical or electronic lock, can be installed on the cabinet door 23 to ensure the security of the protective box 1 when closed and prevent unauthorized entry. The support blocks 24 should be made of materials with sufficient load-bearing capacity and stability, such as cast iron, steel, or concrete, to ensure the protective box 1 can be placed stably on the ground. Anti-slip pads or adjustable feet can be installed at the bottom of the support blocks 24 to adapt to different ground flatness levels and ensure the stability of the protective box 1. The four support blocks 24 should be evenly distributed at the four corners of the bottom of the protective box 1 to bear the weight of the protective box 1 and its internal electrical equipment and distribute the pressure. The motor 6 should be a high-efficiency, low-noise motor to ensure the stability and reliability of the transmission system. A reducer or gearbox should be installed between the threaded rod 7 and the output end of the motor 6 to reduce the speed of the motor 6 and increase the torque of the threaded rod 7, thereby ensuring that the moving block 8 can move smoothly. The threaded fit between the threaded rod 7 and the moving block 8 should be tight and smooth to reduce friction and wear and improve transmission efficiency. The bottom of the drainage trough 15 should be set as a slope to allow rainwater to drain smoothly and avoid water accumulation. A filter screen or drain valve can be installed at the outlet of the drainage trough 15 to prevent debris or small animals from entering the protective box 1. A waterproof layer or waterproof coating can be installed around the drainage trough 15 to improve its waterproof performance. Components such as the protective box 1, rainproof eaves 3, and protective box 16 should be made of lightning protection materials or treated with lightning protection to improve their lightning protection performance. The lightning rod body 14 should be properly electrically connected to the electrical equipment inside the protective box 1 and be equipped with a grounding device to ensure that lightning can be safely conducted to the ground. A lightning protection net or lightning protection strip can be installed around the protective box 1 to further improve its lightning protection capability.

[0031] The electrical equipment protection device in this embodiment, through the carefully designed cabinet door 23, support block 24, transmission system of motor 6 and threaded rod 7, drainage groove 15, control system of electric push rod 17 and top cover 19, and the lightning protection performance of the overall structure, not only realizes the stable lifting and lowering of lightning rod body 14 and reliable movement of top cover 19, but also fully considers waterproofing, dustproofing, lightning protection and long-term operational stability, providing comprehensive and effective protection for electrical equipment.
