Description

Technical Field

[0001] This utility model belongs to the technical field of lightning protection devices, and in particular relates to a chimney lightning protection device. Background Technology

[0002] A chimney is a tall structure used to discharge flue gas and waste gas generated by industrial or civil facilities. Its core function is to create airflow through height difference and thermal pressure effect to achieve the directional emission and diffusion of pollutants.

[0003] To prevent chimneys from being struck by lightning during thunderstorms, lightning rods are typically installed at the top of the chimney. Traditional lightning rods usually have fixed lightning rods. When external factors such as the construction of supporting facilities near the chimney cause equipment taller than the chimney to appear, this equipment can easily become a new lightning strike point, rendering the lightning rod ineffective in protecting the chimney. Therefore, we provide a chimney lightning protection device. Utility Model Content

[0004] The purpose of this utility model is to provide a chimney lightning protection device to solve the problems described in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a chimney lightning protection device, including a protective shell one; a lightning rod is slidably arranged inside the protective shell one, a shell two is fixedly connected to one side of the outer wall of the protective shell one, an adjustment component that works with the lightning rod is rotatably arranged inside the shell two, and a fixing plate is snapped onto the other side of the outer wall of the protective shell one.

[0006] The present invention is further configured such that the adjusting component includes a rack fixed to the outer wall of the lightning rod, a gear rotatably disposed inside the housing two is meshed with the outer wall of the rack, a rotating shaft rotatably connected to the middle of the gear is fixedly connected to the middle of the gear, a worm gear is fixedly connected to the outer wall of the housing two, a worm wheel is meshed with the outer wall of the worm wheel, a worm is rotatably connected to the inner wall of the worm, and a drive source is fixedly connected to the other end of the worm. The drive source is fixed to the inner upper surface of the housing two.

[0007] The present invention is further configured such that an L-shaped plate is fixedly connected to the outer wall of the protective shell, one side of the L-shaped plate penetrates the fixed plate, a limit rod is threadedly connected to the outer wall of the fixed plate, and one end of the limit rod penetrates the fixed plate and the L-shaped plate respectively.

[0008] The present invention is further configured such that the driving source specifically refers to a servo motor.

[0009] The present invention is further configured such that the bottom of the second housing has a plurality of heat dissipation holes for use with the drive source.

[0010] The present invention is further configured such that bolts fixed to the outer wall of the chimney are threadedly connected to both sides of the outer wall of the fixing plate.

[0011] This utility model has the following beneficial effects: 1. This utility model adjusts the height of the lightning rod by adjusting the cooperation between the components of the assembly. This prevents equipment near the chimney from becoming a new lightning strike point when it is higher than the lightning rod, thus preventing the lightning rod from attracting lightning and losing its protective function for the chimney.

[0012] 2. This utility model securely locks the protective shell one by passing the limiting rod through the fixed plate and screwing it into the L-shaped plate through a threaded connection, preventing the protective shell one from falling off the fixed plate, while facilitating the installation and disassembly of the protective shell one.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model is a chimney lightning protection device, including a protective shell 1; a lightning rod 4 is slidably arranged inside the protective shell 1; a shell 3 is fixedly connected to one side of the outer wall of the protective shell 1; an adjustment component that works with the lightning rod 4 is rotatably arranged inside the shell 3; a fixing plate 2 is snapped onto the other side of the outer wall of the protective shell 1; and bolts 15 that are fixed to the outer wall of the chimney are threadedly connected to both sides of the outer wall of the fixing plate 2.

[0022] The fixing plate 2 is fixed to the chimney with bolts 15. When it is necessary to adjust the height of the lightning rod 4, the height of the lightning rod 4 can be adjusted by adjusting the cooperation between the components of the assembly. This prevents equipment near the chimney from becoming a new lightning strike point if it is higher than the lightning rod 4, thus causing the lightning rod 4 to lose its protective function for the chimney.

[0023] Please see Figures 1-5 The adjustment assembly includes a rack 6 fixed to the outer wall of the lightning rod 4. A gear 8 rotatably disposed inside the housing 3 is meshed with the outer wall of the rack 6. A rotating shaft 13 rotatably connected to the middle of the gear 8 is fixedly connected to the inner wall of the housing 3. A worm gear 12 is fixedly connected to the outer wall of the rotating shaft 13. A worm 7 is meshed with the outer wall of the worm gear 12. One end of the worm 7 is rotatably connected to the inner wall of the housing 3. The other end of the worm 7 is fixedly connected to a drive source 10. The drive source 10 is fixed to the inner upper surface of the housing 3. The drive source 10 specifically refers to a servo motor. Multiple heat dissipation holes 14 are provided at the bottom of the housing 3 to cooperate with the drive source 10.

[0024] When the height of the lightning rod 4 needs to be adjusted, connect the external power supply to start the drive source 10. The drive source 10 specifically refers to a servo motor. The drive source 10 is fixed inside the housing 3. At the same time, the heat dissipation holes 14 at the bottom of the housing 3 cool the drive source 10. After the drive source 10 is started, it drives the worm 7, which is fixedly connected to its output end, to rotate. The worm 7 meshes with the worm wheel 12, causing the worm wheel 12 to rotate synchronously. During the rotation of the worm wheel 12, the rotating shaft 13, which is fixedly connected to the worm wheel 12, rotates with the worm wheel 12. The gear 8 on the outer wall of the rotating shaft 13 rotates with the shaft. During the rotation of the gear 8, the gear 8 meshes with the rack 6 on the outer wall of the lightning rod 4, converting the rotational motion into linear motion. Finally, it drives the lightning rod 4 to slide up and down inside the protective housing 1, realizing the height adjustment. When the lightning rod 4 is adjusted to the target height, the drive source 10 is turned off. The meshing structure of the worm 7 and the worm wheel 12 has self-locking properties, which can prevent the lightning rod 4 from sliding on its own due to external forces and maintain the height stability.

[0025] Please see Figure 2 An L-shaped plate 9 is fixedly connected to the outer wall of the protective shell 1. One side of the L-shaped plate 9 passes through the fixed plate 2. A limit rod 16 is threadedly connected to the outer wall of the fixed plate 2. One end of the limit rod 16 passes through the fixed plate 2 and the L-shaped plate 9 respectively.

[0026] The limiting rod 16 is passed through the fixing plate 2 and screwed into the L-shaped plate 9. The two are locked together by the threaded connection to prevent the protective shell 1 from falling off the fixing plate 2, and at the same time facilitates the installation and disassembly of the protective shell 1.

[0027] The operation process of this embodiment is as follows: the fixing plate 2 is fixed to the chimney with bolts 15, the limiting rod 16 is passed through the fixing plate 2 and screwed into the L-shaped plate 9, and the two are firmly locked by threaded connection to prevent the protective shell 1 from falling off the fixing plate 2. When it is necessary to adjust the height of the lightning rod 4, the external power supply is connected to start the drive source 10. The drive source 10 specifically refers to the servo motor. The drive source 10 is fixed inside the shell 2 3. At the same time, the heat dissipation hole 14 at the bottom of the shell 2 3 cools the drive source 10. After the drive source 10 is started, it drives the worm gear 7 fixedly connected to its output end to rotate. The worm gear 7 and the worm wheel 1 2. The meshing drives the worm gear 12 to rotate synchronously. During the rotation of the worm gear 12, the rotating shaft 13, which is fixedly connected to the worm gear 12, rotates with the worm gear 12. The gear 8 on the outer wall of the rotating shaft 13 rotates with the shaft. During the rotation of the gear 8, the gear 8 meshes with the rack 6 on the outer wall of the lightning rod 4, converting the rotational motion into linear motion. Finally, it drives the lightning rod 4 to slide up and down inside the protective shell 1, realizing height adjustment. When the lightning rod 4 is adjusted to the target height, the drive source 10 is turned off. The meshing structure between the worm 7 and the worm gear 12 has self-locking properties, which can prevent the lightning rod 4 from sliding on its own due to external forces and maintain height stability.
