Description

Technical Field

[0001] This utility model relates to the field of lightning protection devices, and in particular to a lightning protection device for fixed towers used in forest fires. Background Technology

[0002] Forest fire fixed towers, also known as lookout towers or observation platforms, are tall architectural structures whose main function is to provide people with a wide field of vision and help to detect abnormal situations on the ground or in the air in a timely manner, playing a particularly important role in forest fire prevention.

[0003] In existing technologies, lightning rods are typically installed on fixed towers to protect them from lightning strikes. However, these lightning rods generally lack protective devices, allowing wind force to act directly on them. Over time, this causes the connection between the lightning rod and its installation location to loosen, reducing the lifespan of the lightning rod. Furthermore, existing lightning rod installations typically use multiple bolts for connection, and these bolts may strip after repeated use, reducing the stability of the lightning rod installation and causing additional inconvenience during installation. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. By using a spring to buffer the vibration generated by the lightning rod, the wind force is prevented from directly acting on the lightning rod and causing damage, thereby achieving the effect of protecting the lightning rod and improving its service life. This is the proposed forest fire fixed tower lightning protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixed tower lightning protection device for forest fires includes a base plate, an mounting plate at the upper end of the base plate, a lightning rod at the upper end of the mounting plate, a connecting wire on the outer wall of the lightning rod, a fixing ring on the outer wall of the lightning rod, multiple circumferentially arranged grooves at the upper end of the mounting plate, a support mechanism for supporting the lightning rod between the fixing ring and the multiple grooves, and a positioning mechanism for positioning the mounting plate at the upper end of the base plate.

[0007] Preferably, the support mechanism includes a movable block slidably connected in the groove, and the upper end of the movable block and the outer wall of the fixed ring are both provided with rotating seats. The number of rotating seats on the outer wall of the fixed ring is four, and each pair of rotating seats is rotatably connected by a connecting plate.

[0008] Preferably, the positioning mechanism includes a plurality of symmetrically arranged rotating rods rotatably connected to the upper end of the base plate, each of the plurality of rotating rods having a limiting plate on its outer wall, and an operating block having a hexagonal shape at the upper end of each rotating rod.

[0009] Preferably, the upper end of the mounting plate has a plurality of symmetrically arranged circular grooves, and the lower end of the mounting plate has a through groove. The through groove cooperates with the limiting plate. Both the through groove and the limiting plate are elliptical in shape. The limiting plate is slidably connected to the bottom of the circular groove. The volume of the operating block is smaller than that of the through groove.

[0010] Preferably, each of the plurality of grooves is provided with a slide rod, which passes through the movable block and is slidably connected to it.

[0011] Preferably, the movable block and the groove are elastically connected by a spring, and the spring is sleeved on the outer wall of the slide rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. By using springs to buffer the vibrations generated by the lightning rod, wind force is prevented from directly acting on the lightning rod and causing damage, thereby protecting the lightning rod and extending its service life.

[0014] 2. By causing the operating block to drive the rotating rod to rotate, the rotating rod drives the limiting plate to rotate, so that the limiting plate and the through slot are in an interlaced state, thereby restricting the mounting plate by the limiting plate, realizing a fast and stable connection of the lightning rod, while bringing convenience to people in the future replacement of the lightning rod.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0021] Reference Figure 1-3 A fixed tower lightning protection device for forest fires includes a base plate 1, an mounting plate 2 on the upper end of the base plate 1, a lightning rod 3 on the upper end of the mounting plate 2, a connecting line 10 on the outer wall of the lightning rod 3, a fixing ring 4 on the outer wall of the lightning rod 3, and multiple circumferentially arranged grooves 5 on the upper end of the mounting plate 2. A support mechanism for supporting the lightning rod 3 is provided between the fixing ring 4 and the multiple grooves 5. The support mechanism includes a movable block 7 slidably connected in the groove 5. The upper end of the movable block 7 and the outer wall of the fixing ring 4 are both provided with rotating seats 8. There are four rotating seats 8 on the outer wall of the fixing ring 4, and each pair of rotating seats 8 is rotatably connected by a connecting plate 9.

[0022] The upper end of the base plate 1 is provided with a positioning mechanism for positioning the mounting plate 2. The positioning mechanism includes multiple symmetrically arranged rotating rods 14 rotatably connected to the upper end of the base plate 1. Each of the multiple rotating rods 14 has a limiting plate 15 on its outer wall. The upper end of the rotating rod 14 is provided with an operating block 16, which is hexagonal. By causing the operating block 16 to drive the rotating rod 14 to rotate, the rotating rod 14 drives the limiting plate 15 to rotate, so that the limiting plate 15 and the through groove 13 are in an interlaced state. This allows the limiting plate 15 to restrict the mounting plate 2, achieving a quick and stable connection of the lightning rod 3, while also facilitating the replacement of the lightning rod 3 in the future.

[0023] The upper end of the mounting plate 2 has multiple symmetrically arranged circular grooves 12, and the lower end of the mounting plate 2 has through grooves 13. The through grooves 13 cooperate with the limiting plate 15. Both the through grooves 13 and the limiting plate 15 are elliptical. The limiting plate 15 is slidably connected to the bottom of the circular grooves 12. The volume of the operating block 16 is smaller than that of the through grooves 13.

[0024] Each of the multiple grooves 5 is equipped with a slide rod 6, which passes through the movable block 7 and is slidably connected to it.

[0025] The movable block 7 and the groove 5 are elastically connected by a spring 11. The spring 11 is sleeved on the outer wall of the slide rod 6. By using the spring 11 to buffer the vibration generated by the lightning rod 3, the wind force is prevented from directly acting on the lightning rod 3 and causing damage to the lightning rod 3, thereby achieving the effect of protecting the lightning rod 3 and improving the service life of the lightning rod 3.

[0026] When using this utility model, during the installation of the lightning protection device on the fixed tower (since the fixed tower for forest fires is existing technology, its related structure is not described in detail in this drawing), the mounting plate 2 is placed on the upper end of the base plate 1, so that the multiple rotating rods 14 on the upper end of the base plate 1 pass through the multiple through slots 13 respectively. At this time, the limiting plate 15 is parallel to the through slots 13. Then, the operating block 16 is rotated using existing tools, so that the operating block 16 drives the rotating rods 14 to rotate, so that the rotating rods 14 drive the limiting plate 15 to rotate, so that the limiting plate 15 and the through slots 13 are in an interlaced state, thereby limiting the mounting plate 2 with the limiting plate 15, realizing a quick and stable connection of the lightning rod 3, while bringing convenience to people in the future replacement of the lightning rod 3;

[0027] Through the rotational connection of multiple pairs of rotating seats 8 and connecting plates 9 between the lightning rod 3 and the mounting plate 2, and the elastic connection of spring 11 between the moving block 7 and the groove 5, the spring 11 buffers the vibration generated by the lightning rod 3, preventing the wind force from directly acting on the lightning rod 3 and causing damage to the lightning rod 3, thereby achieving the effect of protecting the lightning rod 3 and improving the service life of the lightning rod 3.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
