DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0019] In order to solve the problem in the prior art that the strong current of the lightning arrester when struck by lightning may damage the insulator on the lightning arrester, and the damaged insulator cannot play a good insulation effect, and workers need to replace it in time, because the lightning arrester is usually installed high on the pole and far from the ground, the workers on the ground cannot well observe which lightning arrester is damaged, this embodiment provides the following technical solutions:

[0020] A lightning arrester with a signal function, comprising a lightning arrester 1, an insulator 2 is arranged on the lightning arrester 1, a mounting block 4 is arranged at one end of the lightning arrester 1, and a rectangular groove 5 is provided, the rectangular groove 5 is opened on the mounting block 4, a fixed base 6 is arranged at the bottom of the rectangular groove 5, an insulating protection cage 7 is arranged on the fixed base 6, an insulating rod 13 is arranged on the insulating protection cage 7, a splicing base 15 is arranged on the end of the insulating rod 13 away from the insulating protection cage 7, a fixing bolt 14 is arranged at the connection between the insulating rod 13 and the splicing base 15, and a small A wattage bulb 16, a first reserved bolt hole 8 is provided on the mounting block 4, a mounting base 9 is provided on the end of the arrester 1 away from the mounting block 4, the mounting base 9 is connected to the arrester 1 by bolts, a connecting rod 10 is provided on the mounting base 9, the connecting rod 10 and the mounting base 9 are integrally arranged, an assembly plate 11 is provided on the end of the connecting rod 10 away from the mounting base 9, the assembly plate 11 and the connecting rod 10 are integrally arranged, and a connecting block 12 is provided on the end of the mounting base 9 away from the arrester 1, and the connecting block 12 and the mounting base 9 are integrally arranged;

[0021] In this embodiment, when the staff clamps the assembly plate 11 on the connection structure of the utility pole, and then installs the lightning arrester 1 on the utility pole with bolts passing through the bolt holes on the assembly plate 11, and passes one end of the copper wire in the wire through the first reserved bolt hole 8 and wraps it around, the wire is connected to the lightning arrester 1. When the lightning arrester 1 is installed at a high place in the wild, it encounters thunderstorm weather. A small-wattage bulb 16 is provided on the lightning arrester 1. When the lightning arrester 1 is struck by lightning, the current connects the circuit on the small-wattage bulb 16 to light up the bulb, but because the lightning current is very strong, the bulb will burst, and the fragments of the burst bulb will fall below the lightning arrester 1. When the maintenance personnel are on patrol, they do not need to climb up the electric poles, but only need to observe which electric pole has the light bulb fragments under it to determine which electric pole's arrester 1 has been struck by lightning, so as to repair the lightning arrester 1 struck by lightning, saving a lot of manpower. In addition, the small-wattage light bulb 16 is arranged in the insulating protection cage 7. The insulating protection cage 7 can prevent the light bulb fragments from flying out at a very fast speed and cutting the rubber skin of the outer layer of the electric wire when the small-wattage light bulb 16 explodes. Instead, the light bulb flies onto the insulating rod 13, loses its kinetic energy and falls onto the splicing base 15, and is drawn out from the gap of the insulating rod 13 along the inclined splicing base 15 and falls to the ground.

[0022] In this embodiment, a fluorescent mark 3 is provided on the outer surface of the insulator 2. The provision of the fluorescent mark 3 enables the staff to clearly observe the position and number of the insulator 2 in a dim light environment. If the insulator 2 is broken, a position will be vacant between the entire row of fluorescent marks 3, so that the staff can find it in time.

[0023] Working principle: When the staff clamps the assembly plate 11 on the connection structure of the electric pole, and then installs the lightning arrester 1 on the electric pole with bolts through the bolt holes on the assembly plate 11, and passes one end of the copper wire in the electric wire through the first reserved bolt hole 8 and wraps it around, the connection between the electric wire and the lightning arrester 1 is realized. When the lightning arrester 1 is installed at a high place in the wild, it encounters thunderstorm weather. A small wattage bulb 16 is provided on the lightning arrester 1. When the lightning arrester 1 is struck by lightning, the current connects the circuit on the small wattage bulb 16 to light up the bulb, but because the lightning current is very strong, the bulb will explode, and the exploded bulb fragments will fall on the ground under the lightning arrester 1. When the maintenance personnel patrol, they do not need to climb up the electric pole, they only need to observe which electric pole has the bulb fragments under it to determine which electric pole has the lightning arrester 1. When a lightning strike occurs, the lightning arrester 1 that has been struck by lightning can be repaired, which saves a lot of manpower. In addition, the small-wattage light bulb 16 is arranged in the insulating protection cage 7. The insulating protection cage 7 can prevent the light bulb fragments from flying out at a very fast speed and cutting the rubber skin of the outer layer of the wire when the small-wattage light bulb 16 explodes. Instead, the light bulb flies onto the insulating rod 13, and the kinetic energy disappears and falls on the splicing base 15. It is cut out from the gap of the insulating rod 13 along the inclined splicing base 15 and falls to the ground. A fluorescent mark 3 is arranged on the outer surface of the insulator 2. The arrangement of the fluorescent mark 3 enables the staff to clearly observe the position and number of the insulator 2 in a dimly lit environment. If the insulator 2 is broken, there will be a vacant position between the entire row of fluorescent marks 3, so that the staff can find it in time.
