Description

Technical Field

[0001] This utility model relates to the field of lightning protection equipment, and in particular to an integral structure of a lightning rod suitable for mountainous terrain. Background Technology

[0002] With the continuous development of infrastructure construction in my country, new infrastructure projects are gradually shifting from plains areas with better construction conditions to mountainous or plateau regions in the west. These sites differ slightly from previous ones, featuring more undulating terrain, more complex topography, and relatively fragile ecosystems. Furthermore, the climate is more variable and lightning strikes are more frequent. Therefore, when constructing numerous lightning rods to attract or protect against lightning, the design, production, and construction of these rods should comprehensively consider the undulating terrain and complex topography of mountainous and high-altitude areas.

[0003] Existing lightning rods, including the main body used for attracting lightning, are fixed to a concrete foundation on the ground surface by support columns at their base. A common structure involves three support columns at the base of the main body, with their tops fixedly connected to the base. The bottoms of the three support columns are positioned outwards, forming a stable, pyramid-shaped support base. The main body is vertically aligned, and its projection onto the ground surface falls within the triangle formed by the lines connecting the bottoms of the three support columns. However, in mountainous terrain with greater undulations and more complex topography, this type of support base presents a problem: finding suitable fixing points for the bottoms of the support columns is difficult, making it impossible to securely install the rod on the ground surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an integral structure for lightning rods suitable for mountainous terrain.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an overall structure of lightning rod suitable for mountainous terrain, including a lightning rod body, at least three support columns are provided at the bottom of the lightning rod body, the support columns include a fixed rod and a sliding sleeve, the sliding sleeve is sleeved on the fixed rod, the fixed rod and the sliding sleeve are slidably disposed between them, the fixed rod is fixedly connected to the lightning rod body, and the sliding sleeve is fixedly disposed on the ground surface.

[0006] Furthermore, the side wall of the sliding sleeve is provided with a sleeve through hole, including a tightening bolt. The tightening bolt is threadedly engaged with the sleeve through hole and is used to fix the sliding sleeve to the fixed rod.

[0007] Furthermore, the side wall of the sliding sleeve is provided with a pair of sleeve through holes, and the fixing rod is provided with fixing rod through holes evenly distributed along the extension direction of the fixing rod, including through bolts. The through bolts pass through the fixing rod through holes and the sleeve through holes, and the through bolts are used to fix the sliding sleeve to the fixing rod.

[0008] Furthermore, it includes a foundation connection end plate, which is hinged to a sliding sleeve, and the sliding sleeve is set on the ground surface through the foundation connection end plate.

[0009] Furthermore, it includes helical piles, one end of which is fixedly connected to the foundation connection end plate, and helical blades are provided on the helical piles.

[0010] Furthermore, the surface plane includes at least a first surface plane and a second surface plane, which are located on different horizontal planes.

[0011] The beneficial effects of this utility model are: 1. In actual construction, when the support column of the lightning rod is set on the ground surface, if the ground surface is uneven, i.e., there are two ground surfaces at different heights, the length of the support column is flexibly adjusted to make the length of each support column appropriate. This allows each sliding sleeve to be fixed on the ground surface, thus providing a stable installation foundation for the main body of the lightning rod and enabling the installation of the lightning rod.

[0012] Second, by tightening the bolts or using through bolts, the length of the support column can be locked after adjustment to the appropriate length, thus completing the adjustment. The entire operation is convenient and reliable, enabling rapid installation and operation.

[0013] Third, in mountainous terrain, to protect the surrounding ecological environment, it is necessary to minimize concrete pouring. By using helical piles, the drilled helical piles can provide vertical bearing capacity, vertical pull-out resistance, and horizontal resistance for the upper support columns and lightning rods without concrete pouring. Helical piles can also be reused after being pulled from the ground. Furthermore, since concrete pouring is eliminated, the land after the helical piles are removed can be quickly restored, thus effectively protecting and restoring the local environment.

[0014] This invention is particularly applicable to the construction of lightning rods in mountainous terrain. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 The diagram illustrates an embodiment of a lightning rod structure suitable for mountainous terrain. The lightning rod body 1 is constructed from multiple rod-shaped components connected sequentially, resulting in a slender rod-like shape. The lightning rod body 1 is vertically oriented. A bottom mounting plate 11 is fixedly mounted at the bottom of the lightning rod body 1, and the bottom mounting plate 11 is horizontally positioned. Three support columns 2 are positioned below the bottom mounting plate 11, evenly spaced around the axis of the lightning rod body 1. Each support column 2 consists of a fixed rod 21 and a sliding sleeve 23 slidably mounted on the fixed rod 21. Specifically, the top of the fixed rod 21 is fixedly connected to the bottom mounting plate 11. The tops of the fixed rods 21 of the three support columns 2 are close together and fixedly mounted to the bottom of the bottom mounting plate 11, while the sliding sleeves 23 of the three support columns 2 are spaced apart, thus forming a... Figure 1 The diagram shows a stable support structure that approximates a pyramid shape. Among them, such as... Figure 2 As shown, the projection of the lightning rod body 1 onto the ground plane is set within the triangular area formed by the line connecting the foundation connection end plate 24 at the bottom of the three support columns 2, ensuring that the center of gravity of the overall structure formed by the lightning rod body 1 and the three support columns 2 is in a stable state.

[0020] Regarding the specific structure of the support column 2, the sliding sleeve 23 is sleeved on the fixed rod 21, and the fixed rod 21 and the sliding sleeve 23 are slidably connected. The fixed rod 21 is fixedly connected to the lightning rod body 1, and the sliding sleeve 23 is hinged to the foundation connection end plate 24. In actual use, the sliding sleeve 23 is fixedly installed on the ground surface through the foundation connection end plate 24, and the position of the sliding sleeve 23 is relatively fixed. The length of the support column 2 can be changed by sliding the fixed rod 21. After the fixed rod 21 is slid to the desired position, the position between the sliding sleeve 23 and the fixed rod 21 can be locked in the following two ways: 1. The side wall of the sliding sleeve 23 is provided with a sleeve through hole, including a tightening bolt. The tightening bolt is threaded into the sleeve through hole and is used to fix the sliding sleeve 23 to the fixed rod 21. Simply tighten the tightening bolt and make it fit tightly against the side wall of the fixed rod 21. The friction between the tightening bolt and the fixed rod 21 locks the position between the sliding sleeve 23 and the fixed rod 21. 2. The side wall of the sliding sleeve 23 is provided with a pair of sleeve through holes. The fixed rod 21 has fixed rod through holes evenly distributed along its extension direction, including through bolts 22. The through bolts 22 pass through the fixed rod through holes and the sleeve through holes, and are used to fix the sliding sleeve 23 to the fixed rod 21. The through bolt 22 passes through the through hole of the fixed rod and the through hole of the sleeve. Both ends of the through bolt 22 extend to the outside of the through hole of the sleeve and are then locked by the lock nut. This can also lock the position between the sliding sleeve 23 and the fixed rod 21.

[0021] The bottom of the basic connection end plate 24 is set tightly against the corresponding ground surface plane, such as... Figure 1 As shown, taking three support columns 2 as an example, the three corresponding foundation connection end plates 24 are respectively set on three ground surfaces at different heights, namely the first ground surface 4, the second ground surface 5, and the third ground surface 6, and the first ground surface 4, the second ground surface 5, and the third ground surface 6 are located at different heights. By adjusting the length of the corresponding support columns 2, the bottom of the foundation connection end plate 24 of each support column 2 can be tightly set against the corresponding ground surface. For example, Figure 1 As shown, a spiral pile 3 is vertically fixed to the bottom of the foundation connection end plate 24. The spiral pile 3 is a rod-shaped structure with a pointed bottom end and spiral blades 31 spirally arranged on it. In actual use, rotating the spiral pile 3 causes the spiral blades 31 to interact with the surrounding soil, allowing the spiral pile 3 to drill downwards to the required depth, eliminating the damage to the soil caused by concrete pouring. The spiral pile 3 should fully consider the upper loads of the support column 2 and the lightning rod body 1. Using large-sized spiral blades 31 can provide vertical pull-out resistance. The spiral pile 3 needs to be galvanized to ensure it does not rust even after prolonged penetration into the soil.
