Description

Technical Field

[0001] This utility model relates to the field of lightning protection equipment, and more specifically, to a lightning protection device for concrete tower chimneys. Background Technology

[0002] Concrete chimneys are key structures in industrial facilities. Through their vertical, towering structure, they utilize the principle of thermal pressure difference to guide combustion exhaust gases, dust, or chemical tail gases into the upper atmosphere, promoting the diffusion and dilution of pollutants in the atmosphere, significantly reducing ground concentration, and minimizing direct impact on the surrounding environment. Reinforced concrete structures bear wind loads. During thunderstorms, to prevent damage to tall chimneys, lightning protection devices are needed. The core function of these devices is to safely conduct lightning current to the ground through a systematic structure, minimizing the damage caused by lightning strikes.

[0003] Currently, most lightning protection devices used for concrete towers and chimneys have the following problems:

[0004] For example, a lightning protection device for chimneys, disclosed in publication number 202221913919.6, can be installed on the chimney using an I-beam bracket. However, during installation, it is mostly fixed by multiple bolts or welding. During use, workers need to disassemble and remove it periodically to check whether it can be used normally. The installation and disassembly are relatively troublesome during maintenance, requiring the removal of multiple bolts or cutting of welded parts. This makes it inconvenient to install and disassemble the lightning rod. At the same time, when installing the lightning rod, the clamps and fixing devices are connected by multiple bolts to fix the lightning rod. During installation and disassembly, workers need to use tools to install and remove multiple bolts, making the installation and disassembly cumbersome and inconvenient to install and disassemble the lightning rod.

[0005] Therefore, we have made improvements to this and proposed a lightning protection device for concrete tower chimneys. Utility Model Content

[0006] The purpose of this utility model is to address the current inconvenience of convenient installation and disassembly of lightning rods, as well as the inconvenience of installing and disassembling them.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Lightning protection devices for concrete towers and chimneys to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] The device includes a chimney body, a fixed frame fixedly connected to the chimney body, a bidirectional threaded rod rotatably connected to the fixed frame, a first turntable fixedly connected to the bidirectional threaded rod, a movable frame threadedly connected to the bidirectional threaded rod, a pressing block fixedly connected to the movable frame, an mounting plate mounted on the fixed frame, a positioning box fixedly connected to the mounting plate, a connecting frame fixedly connected to the mounting plate, a mounting box bolted to the connecting frame, a threaded sleeve bearing connected to the mounting box, a second turntable fixedly connected to the threaded sleeve, a bevel gear fixedly connected to the threaded sleeve, a transmission threaded rod threadedly connected to the threaded sleeve, a clamping plate fixedly connected to the transmission threaded rod, and a rubber pad fixedly connected to the clamping plate.

[0011] As a preferred technical solution of this application, the movable frame is symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the movable frame corresponds one-to-one with the extrusion block.

[0012] As a preferred technical solution of this application, the side end face of the movable frame is in contact with the inner side face of the fixed frame, and the cross-section of the extrusion block is an isosceles triangle.

[0013] As a preferred technical solution of this application, the positioning box has inclined grooves on both sides, and the cross-section of the moving frame and the connecting frame is "L" shaped.

[0014] As a preferred technical solution of this application, the threaded sleeves are distributed at equal angles on the mounting box, and the threaded sleeves correspond one-to-one with the clamping plates through the transmission threaded rod.

[0015] As a preferred technical solution of this application, a guide rod is fixedly connected to the clamp, a lightning rod is provided on the mounting box, and the cross-section of the clamp is arc-shaped.

[0018] 1. Equipped with a bidirectional threaded rod; when disassembling the equipment, the first turntable on one side can be rotated to drive the first turntable to rotate, and the first turntable can drive the two moving frames on both sides to move outward.

[0033] Example 2:

[0034] The solution in Example 1 will be further described below with reference to its specific working method.

[0035] like Figure 3 As shown, in a preferred embodiment, based on the above method, the movable frame 5 is symmetrically distributed on the left and right sides of the bidirectional threaded rod 3, and the movable frame 5 corresponds one-to-one with the extrusion block 6, which can ensure that the extrusion blocks 6 on both sides can be inserted into the positioning box 8 for fixed positioning.

[0036] like Figure 3 As shown, in a preferred embodiment, based on the above method, the side end face of the movable frame 5 is in contact with the inner side face of the fixed frame 2, and the cross-section of the extrusion block 6 is an isosceles triangle, which can ensure that the isosceles triangle inclined surface can extrude the positioning box 8 for limiting.

[0037] like Figure 3 As shown, in a preferred embodiment, based on the above method, the positioning box 8 is further provided with inclined grooves on both sides, and the cross-section of the moving frame 5 and the connecting frame 9 is "L" shaped, which can ensure that the moving frame 5 can smoothly drive the pressing block 6 into the positioning box 8.

[0038] like Figure 5 As shown, in a preferred embodiment, based on the above method, the threaded sleeves 11 are further distributed at equal angles on the mounting box 10. The threaded sleeves 11 correspond one-to-one with the clamping plates 15 through the transmission threaded rods 14, which can ensure that the clamping plates 15 distributed at equal angles can clamp and limit the installed lightning rods 18.

[0040] Specifically, the lightning protection device originally intended for concrete towers and chimneys should be used in conjunction with: Figure 1-5 When disassembling the equipment, the first turntable 4 on one side can be rotated to drive the first turntable 4 to rotate. The first turntable 4 can drive the two moving frames 5 to move outward. At the same time, the pressing block 6 on the moving frame 5 can be released from the positioning box 8, and the positioning box 8 clamped and fixed can be released to disassemble the parts connected to the mounting plate 7 for subsequent inspection and maintenance, thus improving disassembly efficiency. When installing and resetting, the positioning box 8 is inserted into the fixed frame 2, and the bidirectional threaded rod 3 is driven to rotate in the opposite direction. The two moving frames 5 drive the pressing block 6 to move inward. At the same time, the pressing block 6 is inserted into the positioning box 8, and the inclined surface of the pressing block 6 can press and fix the positioning box 8, which can improve installation stability and improve installation and disassembly efficiency for subsequent inspection and maintenance. When the mounting box 10 is removed later, it can be connected and disassembled through the connecting frame 9.
