Technical Field

[0001] The utility model relates to the technical field of lightning protection and grounding, and in particular to a lightning protection and grounding device for a skid-mounted gas station. Background Art

[0002] The skid-mounted gas station is designed with safety, environmental protection and mobility as the core concepts. It is a skid-mounted gas station that integrates ground fireproof and explosion-proof oil storage tanks, gas dispensers and automatic fire extinguishers. This type of gas station is small in size and occupies little space; it is easy to install and can be moved as a whole. The oil storage tanks of this gas station require strict preparation requirements, requiring that they will not explode when encountering open flames, static electricity, impact, lightning strikes, gunshots, welding, and accidental violent collisions. A Chinese patent discloses a new type of lightning protection grounding body (authorization announcement number CN203288775U). The patent technology discloses a lightning protection grounding device, and particularly relates to a new type of lightning protection grounding body. The technical scheme is: including a lightning protection grounding body, a conductive graphite wire mesh, a stainless alloy composite material reinforcement mesh, a hose protective sleeve, and a double-hole connection terminal. A conductive flexible graphite paper core is arranged in the inner center of the lightning protection grounding body, and a conductive graphite wire mesh is woven on the outside of the conductive flexible graphite paper core. A layer of stainless alloy composite material reinforcement mesh is added to the conductive graphite wire mesh. A hose protective sleeve is arranged at the exposed end of the lightning protection grounding body on the ground; and a double-hole connection terminal is arranged at the other end of the lightning protection grounding body. The beneficial effects are: reasonable structure, corrosion resistance, high strength, durability, tensile resistance, compression resistance, not easy to break, high and low temperature resistance, anti-freezing, high toughness, and bendability.

This patented technology solves the problem.

[0003] However, in the prior art, when performing lightning protection grounding for skid-mounted gas stations, a single grounding wire is connected to the ground and is easily pulled out, making the installation unstable. It is necessary to solve the problem in the prior art that multiple grounding wires can be connected to the ground while increasing the stability of the grounding wire installation in the ground.

[0004] Therefore, those skilled in the art provide a lightning protection and grounding device for a skid-mounted gas station to solve the problems raised in the above background technology. Utility Model Content

[0012] Preferably, a limiting plate is integrally fixed to the outer portion of the grounding rod corresponding to the limiting groove, and the limiting plate is movably located inside the limiting groove.

[0013] A blocking block is fixed inside the bottom end of the grounding screw rod, and the blocking block is used to limit the bottom end of the grounding rod;

[0014] An insulating expansion sleeve is arranged between the grounding screw rod and the screw rod.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model is connected to the lightning rod of the skid-mounted gas station through a grounding cable. The grounding screw rod and its lightning protection grounding structure can effectively divert lightning into the ground, thereby protecting the skid-mounted gas station from lightning. This design ensures the safety of the gas station and reduces the potential risks brought by lightning. The grounding rod is tilted and penetrates deep into the ground, making the installation of the grounding screw rod more stable. This tilted shape design increases the contact area between the grounding rod and the soil, improves the stability of the grounding system, and further enhances the lightning protection effect.

[0017] 2. The utility model can easily control the screw rod to spirally drive inside the grounding screw rod by manually turning the hand wheel, so that the grounding rod and the bottom rod gradually go deep into the ground. This installation method is simple and fast, does not require complicated tools or equipment, and reduces installation costs and time. The grounding rod can automatically adapt to the conditions of the underground soil during the descent process, and ensures that the grounding branch line can be effectively inserted into the ground by tilting outward. This design enables the grounding system to adapt to different geological environments and improves its versatility and applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0028] The lightning protection grounding structure 5 includes a bottom shaft 501 movably arranged inside the grounding screw rod 1, a screw 505 is rotatably mounted on the top of the bottom shaft 501, and the screw 505 is spirally arranged inside the grounding screw rod 1;

[0029] The bottom of the bottom shaft rod 501 is fixedly equipped with an axis adjustment seat 502 corresponding to the limiting groove 3, and a grounding rod 503 is rotatably installed inside the axis adjustment seat 502; the bottom end of the grounding rod 503 is integrally connected to a bottom plug rod 504; a grounding cable 506 is installed at the center of the axis adjustment seat 502, and a grounding branch line 507 is electrically connected to the bottom end of the grounding cable 506;

[0030] The grounding branch line 507 is installed inside the grounding rod 503 and the bottom rod 504; the screw rod 505 is rotatably sleeved outside the grounding cable 506; a bearing cylinder 508 is integrally fixed to the top of the screw rod 505, and a hand-turned wheel 509 is fixedly mounted outside the bearing cylinder 508;

[0031] A limiting plate 510 is fixed to the outside of the grounding rod 503 corresponding to the limiting groove 3, and the limiting plate 510 is movably located inside the limiting groove 3; a blocking block 4 is fixed to the inner side of the bottom end of the grounding screw rod 1, and the blocking block 4 is used to limit the bottom end of the grounding rod 503; an insulating telescopic sleeve 2 is assembled between the grounding screw rod 1 and the screw 505.

[0032] According to the above embodiments, the working principle of the present invention is:

[0033] The grounding cable 506 is connected to the lightning rod of the skid-mounted gas station;

[0034] When the grounding screw rod 1 is deeply buried in the ground, the grounding screw rod 1 and its lightning protection grounding structure 5 are directly inserted into the ground, and the hand wheel 509 is rotated manually, and the hand wheel 509 drives the screw rod 505 to rotate through the load-bearing cylinder 508. The screw rod 505 is spirally transmitted along the inside of the grounding screw rod 1, so that the screw rod 505 descends along the grounding screw rod 1. The descending screw rod 505 is subjected to force on the adjustment shaft seat 502, and drives the bottom rod 504 at the bottom of the grounding rod 503 through the adjustment shaft seat 502 to go deep into the ground. In the soil, since the bottom rod 504 is blocked by the soil, the grounding rod 503 rotates along the adjustment seat 502, so that the grounding rod 503 passes through the limiting plate 510 and moves obliquely outward when descending on the inside of the limiting groove 3. The grounding branch line 507 is inserted into the ground in an inclined shape through the four grounding rods 503, and the grounding cable 506 is conductive through the grounding branch line 507, which is convenient for shunting lightning into the ground. At the same time, the grounding rod 503 is inclined and penetrates deep into the ground, which is convenient for the stable installation of the grounding screw rod 1.
