Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection structure improvement, in particular to a portable micro-current lightning arrester. Background Art

[0002] Lightning rods are a common structure for people to reduce lightning strike losses, but their working method of drawing lightning into the ground can cause various hazards to the current flowing through the building. For example, patent No. 2017110398019 discloses an equivalent ion lightning arrester unit and a comprehensive lightning protection system, which are respectively installed with an upper electrode and a lower electrode at the upper and lower ends of the insulating medium, and a number of lightning rods are arranged at the upper end of the upper electrode. The structure attracts the charge of the thundercloud downward through the lightning rod, and the lower electrode attracts the charge of the earth upward. When the charge at the upper electrode and the lower electrode accumulates to a certain amount, a discharge is generated on the opposite surface of the upper electrode and the lower electrode. The discharge ionizes the air on the side, and the positive charge in the ionized plasma is neutralized with the charge of the thundercloud, and the negative charge in the plasma is neutralized with the charge of the earth, and finally the leakage voltage at the lower electrode is very low, thereby achieving that the building where the lightning arrester unit is installed will not produce the hazard of large current caused by the lightning rod. As people's living standards improve, people have an increasing demand for going out for fun, dinners or photography. However, lightning strikes often occur in the wild, and there is no more convenient lightning protection method. The structure of the above patent is large in size and not suitable for people to carry around. That is, developing a lightning protection device that is convenient, portable and easy to use can make people safer when doing outdoor activities. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A portable micro-current lightning arrester comprises an insulating medium 8, an upper electrode 7 and a lower electrode 10 are respectively sleeved on the upper and lower ends of the insulating medium, and a plurality of lightning arrester pins 2 are arranged on the upper end surface of the upper electrode. Figure 2 As shown, a plurality of convex plates 9 extending along the surface of the insulating medium toward the lower electrode are evenly arranged on the surface of the upper electrode 7 facing the lower electrode, and a gap is reserved between the lower end of each convex plate and the surface 13 of the lower electrode facing the upper electrode; Figure 1 As shown, the surface of the lower electrode facing the upper electrode between two adjacent convex plates is provided with a convex plate 9 extending along the surface of the insulating medium toward the upper electrode, and a gap is reserved between the upper end of the convex plate and the surface 6 of the upper electrode facing the lower electrode; and a gap is reserved between adjacent convex plates. The surface of each convex plate that is bonded to the insulating medium is the same shape as the surface of the insulating medium, that is, the surface opposite to the convex plate and the insulating medium is bonded together.

[0024] like Figure 1 As shown, the surface 6 between the convex plates 9 on the upper electrode facing the lower electrode is in an upward concave shape. Figure 2 As shown, the surface 13 between the convex plates 9 on the lower electrode facing the upper electrode is a downward concave shape. The concave shape is an arc, and the lower end surface of the convex plate provided on the upper electrode and the upper end surface of the convex plate provided on the lower electrode are both arc-shaped to match the arc of the concave shape.

[0025] When discharging, the concave shape and the arc shape of the corresponding convex plate match each other, and discharge is achieved there; and the relative surfaces between the two adjacent convex plates match each other, and discharge is achieved there; it can be seen that there is enough discharge gap and more discharge surface between the upper electrode and the lower electrode.

[0026] In order to protect the lightning rod, the upper electrode buckle is equipped with a protective cover 3, and the upper end face or upper end side face of the protective cover is provided with an opening 1 for exposing the lightning rod 2. An upper end cover 15 is provided at the upper end of the upper electrode, and the upper end face of the upper end cover is provided with a lightning rod 2. The convex edge 11 provided on the side face of the upper end cover is pressed on the upper end face of the upper electrode, and the bottom edge of the upper end cover is pressed on the upper end face of the insulating medium. At least one discharge hole 4 is provided at the lower end of the protective cover, and the discharge hole is used to discharge rainwater, dust and other debris entering the protective cover from the opening. The lower end 5 of the protective cover is sleeved outside the upper end of the upper electrode, and the lower edge of the discharge hole is slightly lower than the convex edge of the end cover to facilitate the discharge of impurities such as rainwater or dust.

[0027] A base 19 is provided inside the lower electrode, and a boss 18 extending into the insulating medium is provided on the upper end face of the base, the side face of the boss contacts the surface on the inner side of the lower end of the insulating medium, a boss 17 formed on the upper end face of the boss extends into the interior 14 of the insulating medium, and a convex edge 11 provided on the side face of the base presses on the bottom face of the lower electrode. An extension column 16 is also provided on the boss, and the sides of the boss and the extension column retain a gap with the inner surface of the insulating medium, and the upper end face of the extension column retains a gap with the bottom face of the end cover 15. A connecting column 12 is provided on the bottom face of the base, and the connecting column can be made of insulating material or metal material. When in use, the connecting column is installed on a retractable bracket, the top of a tent, or in a sleeve provided on a vehicle, etc., as long as the height of the lightning rod is ensured to be higher than the height of the active crowd. Of course, in order to achieve a better protection effect, it is better to install the connecting column on a higher bracket.

[0028] The convex column and the extension column are located in the space inside the insulating medium, and the two form a built-in electrode. The setting of the electrode can obviously make the discharge between the upper electrode and the lower electrode occur in advance, that is, when the voltage difference between the upper electrode and the lower electrode reaches a certain value, the discharge begins and plasma is formed to neutralize the charge of the thundercloud and the ground. After multiple tests, the above conclusions have been verified. The discharge can occur at less than 30,000 volts, which greatly improves the protection effect of the utility model and ensures the safety of users.

[0029] The arc-shaped bottom surface at the bottom, the side surfaces on both sides and the surface of the upper electrode facing the lower electrode beside the convex plates of the upper electrode are all provided with convex teeth. The provision of the convex teeth is beneficial to the uniformity of the gap discharge between the upper electrode and the lower electrode, that is, the gap discharge occurs roughly evenly between the convex teeth and the surface of the lower electrode spaced and close thereto or the surface of the convex plates provided on the lower electrode.

[0030] As shown in the figure, the upper electrode is symmetrically provided with two convex plates facing downward, and the lower electrode is symmetrically provided with two convex plates facing upward. There are four lightning rods, and the top of each lightning rod is in the shape of a sharp needle, and there are four openings and discharge holes. The upper electrode and the lower electrode can be fixed together with the insulating medium by common connection structures such as bonding and bolts, and the end cover and the base can be fixed together with the insulating medium by common connection structures such as bonding and bolts. The protective cover can also be fixed together with the upper electrode by common connection structures such as bonding and bolts. The lightning rod, end cover, base, convex column, upper electrode, lower electrode and convex plate are all made of aluminum alloy.

[0031] In the utility model, the upper electrode is provided with a plurality of convex plates facing downward, and the lower electrode is provided with a plurality of convex plates facing upward, and gaps are reserved between the convex plates, and gaps are reserved between the convex plates provided by the lower electrode and the upper electrode, and between the convex plates provided by the upper electrode and the lower electrode. The surface of the upper electrode facing the convex plates provided by the lower electrode or the surface of the lower electrode facing the convex plates provided by the upper electrode are both concave shapes. Through the above structure, the distance between the upper electrode and the lower electrode can be smaller, but there are sufficient discharge gaps and matching discharge surfaces between the convex plates and the concave shapes, and between the convex plates. In addition, the diameters of the upper electrode, the lower electrode and the insulating medium can also be smaller, but will not affect the above-mentioned discharge gaps and discharge surfaces, that is, the purpose of lightning protection can still be effectively achieved, but the overall volume and weight can be made smaller, which is convenient for people to carry and use.
