Description

Technical Field

[0001] This utility model relates to the field of lightning protection device technology, specifically a lightning protection device for power plants. Background Technology

[0002] A power plant, also known as a power station, is a factory that converts various primary energy sources found in nature into electrical energy. In the process of generating electricity, existing power plants, due to their building height, have lightning rods installed on the top of the building to avoid lightning strikes. A lightning rod is a device used to protect buildings, equipment, and other facilities from lightning strikes.

[0003] Existing lightning rods require bolts to be fixed to the building roof during practical use. However, when a lightning rod becomes damaged and needs replacement after long-term use, multiple bolts need to be removed, which is cumbersome and affects the efficiency of lightning rod replacement. Moreover, the bolts are prone to corrosion, further increasing the difficulty of disassembly. Therefore, we propose a lightning protection device for power plants. Utility Model Content

[0004] The purpose of this invention is to provide a lightning protection device for power plants, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightning protection device for a power plant, comprising a base, a connecting seat connected to the top of the base, a fixing block connected to the top of the connecting seat, a connecting block fixed to the top of the fixing block, and a lightning rod fixedly connected to the top of the connecting block.

[0006] The bottom of the connecting block is fixedly connected to a plug-in post, which is a square post. The plug-in post is inserted into a slot opened on the top of the fixed block. The four side walls of the slot cavity are provided with mounting grooves. A locking block is inserted into the cavity of the mounting groove. The outer end face of the locking block is arc-shaped. The inner end of the locking block is fixedly connected to a first spring. The outer end of the first spring is fixedly connected to the inner wall of the mounting groove. The outer wall of the plug-in post is provided with a locking groove corresponding to the locking block.

[0007] By adopting the above technical solution, the base is first installed and fixed. Then, the plug-in post at the tail end of the connecting block is inserted into the slot at the top of the fixing block. As the plug-in post goes deeper, it will act on the locking block and be squeezed into the mounting groove. When the plug-in post descends to a certain position, the locking block aligns with the slot, and the first spring pushes the locking block into the slot to lock it in place, thus enabling a quick connection. When it is necessary to disassemble and replace the lightning rod, the plug-in post is pulled out forcefully. Because the arc surface of the locking block and the slot are engaged, the locking block can be pulled back into the mounting groove when pulled up, so the plug-in post can be directly pulled out. This makes disassembly and assembly convenient and quick, and facilitates the replacement of damaged lightning rods.

[0008] In a preferred embodiment of this utility model, a groove is provided at the bottom of the plug-in post, a movable block is inserted into the groove, a second spring is fixedly connected to the inner end of the movable block, and the outer end of the second spring is fixedly connected to the inner wall of the groove.

[0009] By adopting the above technical solution, after the plug is inserted into the slot, the movable block at its tail end will press against the bottom of the slot cavity, thereby compressing the second spring in the opposite direction. The second spring will give the plug a certain counter-pushing force, which helps to improve the stability of the locking block and the slot and helps to avoid shaking.

[0010] In a preferred embodiment of this utility model, the bottom of the connecting seat is provided with limiting grooves on all four sides. A matching limiting slider is inserted into the middle of the inner cavity of the limiting groove. One end of a damper is fixedly connected to both side walls of the limiting slider. The outer end of the damper is fixedly connected to the inner wall of the limiting groove. The bottom of the limiting slider is fixedly connected to the base.

[0011] By adopting the above technical solution, the limiting slider at the bottom of the connector is fixedly connected to the base, so that when the wind blows, it will act on the damper, which will help to reduce the impact of the wind, thereby reducing swaying and ensuring connection stability, while also reducing the possibility of damage to the lightning rod.

[0012] In a preferred embodiment of this utility model, limiting rods are fixedly connected to both sides of the bottom of the connecting block, and the limiting rods are inserted into the limiting holes opened on the top of the fixed block.

[0013] By adopting the above technical solution, the setting of the limiting rod can further improve the stability of the connection between the connecting block and the fixing block after being inserted into the limiting hole.

[0014] In a preferred embodiment of this utility model, the lightning rod is fixedly connected to four sides of its outer wall with traction ropes, and the outer ends of the traction ropes are fixedly connected to the top of the connecting block.

[0015] By adopting the above technical solution and setting up the traction rope, the stability of the lightning rod can be improved.

[0016] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0017] By adopting the above technical solution, the installation holes facilitate the installation and fixation of the entire device.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The lightning protection device for power plants according to the present application allows the locking block to be locked into the slot on the outer wall of the plug-in post after the plug-in post is inserted into the slot at the top of the fixing block, thereby achieving quick locking. The limiting rod is used for positioning to ensure stable connection. At the same time, the plug-in post can be lifted by pulling it out directly when disassembling, which helps to improve the convenience of disassembly and assembly.

[0020] After the plug is inserted into the slot, the movable block at its tail end will press against the bottom of the slot cavity, which will compress the spring in the opposite direction. The spring will give the plug a certain counter-pushing force, which will help improve the stability of the engagement between the locking block and the slot and help avoid shaking.

[0021] The limiting slider at the bottom of the connector is fixedly connected to the base, so that when the wind blows, it will act on the damper, which will help to reduce the impact of the wind, thus reducing swaying and ensuring connection stability, while also reducing the possibility of damage to the lightning rod.

[0031] Please see Figure 1-4This utility model provides a technical solution: a lightning protection device for power plants, including a base 1, a connecting seat 2 fixedly connected to the top of the base 1, a fixing block 3 connected to the top of the connecting seat 2, a connecting block 31 fixedly connected to the top of the fixing block 3, and a lightning rod 32 fixedly connected to the top of the connecting block 31.

[0032] A plug-in post 34 is fixedly connected to the bottom of the connecting block 31. The plug-in post 34 is a square post and is inserted into a slot opened on the top of the fixed block 3. The four side walls of the slot cavity are provided with mounting grooves. A locking block 36 is inserted into the cavity of the mounting groove. The outer end face of the locking block 36 is arc-shaped. The inner end of the locking block 36 is fixedly connected to a first spring 37. The outer end of the first spring 37 is fixedly connected to the inner wall of the mounting groove. A locking groove is opened on the outer wall of the plug-in post 34 corresponding to the locking block 36.

[0033] It should be understood that in actual use, the base 1 is first installed and fixed, and then the plug 34 at the end of the connecting block 31 is inserted into the slot at the top of the fixing block 3. As the plug 34 goes deeper, it will cause the locking block 36 to be squeezed into the mounting groove. When the plug 34 descends to a certain position, the locking block 36 aligns with the slot, and the first spring 37 pushes the locking block 36 into the slot to engage, thus enabling quick connection. When it is necessary to disassemble and replace the lightning rod 32, the plug 34 is pulled out forcefully. Since the arc surface of the locking block 36 engages with the slot, the locking block 36 can be retracted into the mounting groove again when pulled up, so that the plug 34 can be directly pulled out, making disassembly and assembly convenient and quick, and thus facilitating the replacement of the damaged lightning rod 32.

[0034] Furthermore, traction ropes 33 are fixedly connected to all four sides of the outer wall of the lightning rod 32. The outer end of the traction rope 33 is fixedly connected to the top of the connecting block 31. The traction rope 33 enhances the stability of the lightning rod 32.

[0035] Furthermore, limiting rods 35 are fixedly connected to both sides of the bottom of the connecting block 31. The limiting rods 35 are inserted into the limiting holes opened on the top of the fixing block 3. The setting of the limiting rods 35 can further improve the stability of the connection between the connecting block 31 and the fixing block 3 after being inserted into the limiting holes.

[0036] It is worth mentioning that mounting holes are provided at the four corners of the top of the base 1, which makes it easy to install and fix the entire device.

[0037] like Figure 2 and 4 As shown; a groove is provided at the bottom of the plug post 34, a movable block 38 is inserted into the groove, a second spring 39 is fixedly connected to the inner end of the movable block 38, and the outer end of the second spring 39 is fixedly connected to the inner wall of the groove.

[0038] It should be understood that after the plug pin 34 is inserted into the slot, the movable block 38 at its tail end will press against the bottom of the slot cavity, thereby compressing the second spring 39 in the opposite direction. The second spring 39 will give the plug pin 34 a certain counter-pushing force, which will help improve the stability of the engagement between the card block 36 and the card slot and help avoid shaking.

[0039] like Figure 1 and 2 As shown; the bottom of the connecting seat 2 has four limit grooves 21 on all four sides. A matching limit slider 22 is inserted into the middle of the inner cavity of the limit groove 21. One end of a damper 23 is fixedly connected to both sides of the limit slider 22. The outer end of the damper 23 is fixedly connected to the inner wall of the limit groove 21. The bottom of the limit slider 22 is fixedly connected to the base 1.

[0040] It should be understood that the limiting slider 22 at the bottom of the connecting seat 2 is fixedly connected to the base 1, so that when the wind blows, it will act on the damper 23, which will help to reduce the impact of the wind, thus reducing the shaking and ensuring the stability of the connection, while also reducing the possibility of damage to the lightning rod 32.

[0041] Furthermore, the components included in this utility model for a lightning protection device for power plants are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching monitoring computer and power supply, are connected by wires. The specific connection method should refer to the working principle described above, and the electrical connection between each electrical component should be completed in the order of operation.
