Problems solved by technology

[0002] The functions of the existing lightning protection equipment are becoming more and more mature, and the lightning protection effect and field are also constantly expanding. Computers, home appliances, office equipment, etc. need centralized lightning protection devices. The lightning protection box can meet the above required lightning protection effects. According to the current According to the usage situation, the products in the field of lightning protection boxes are about 10-15 years old. Lightning protection is no small matter. If a product is used for too long, its performance will be greatly reduced due to the aging of the product, and the lightning protection effect and ability will also be reduced. Products that have lost their lightning protection capabilities are still used for lightning protection, which will be a great harm to people

Embodiment 1

[0015] Embodiment 1: in combination with figure 1 , 2 , 4 description.

[0016] A mechanical self-destruct lightning protection box, comprising a housing 4 and a power input port 1 and a power output port 2 made on it, the housing 4 is built with a self-destruct switch assembly (3); the self-destruct The switch assembly 3 includes a fixed-speed motor 6 connected to the power input terminal with gear one 5; gear one 5 is meshed with gear two 7; gear two 7 is meshed with gear three 8; gear three 8 is coaxial with gear four 9. Gear four 9 is meshed with gear five 10 in the horizontal direction, and the upper end of the circumference of gear five 10 has a moving electrode 11, and the moving electrode 11 is in contact with the lower surface of the static electrode 12; the upper surface of the static electrode 12 is in contact with the power output port 2; The moving electrode 11 and the static electrode 12 are connected in series on the output circuit of the surge protector.

Embodiment 2

[0018] Embodiment 2: in combination with figure 1 , 2 , 3 description

[0019] The transmission ratio of the first belt gear 5 and the second gear 7 is 1:30-31; the transmission ratio of the second gear 7 and the third gear 8 is 1:12; the transmission ratio of the fourth gear 9 and the fifth gear 10 is 1:20.

[0020] The static electrode 12 is called a semicircle. The self-destruct switch is composed of a moving electrode 11 and a static electrode 12 connected in series; the switch is a one-time switch.

[0021] For example, if the surge protector is designed for ten years, the transmission ratio of gear 4 9 and gear 5 10 is 1:20, and so on. When gear 4 rotates 10 times, gear 5 drives the moving electrode 11 on the static electrode. Large semi-circular movement separates the moving and static electrodes, and cuts off the output power without reset.

Abstract

The invention belongs to the technical field of lightning protection, and provides a mechanical self-destruction lightning protection box. The mechanical self-destruction lightning protection box mainly comprises a self-destruction switch assembly, wherein the self-destruction switch assembly comprises a constant-speed motor which is connected with the input end of a power supply and is provided with a gear I; the gear I is meshed with a gear II; the gear II is meshed with a gear III; a gear IV is coaxially arranged on the gear III; a gear V is meshed in the horizontal direction of the gear IV; a movable electrode is arranged at the circumferential upper end of the gear V; the movable electrode is in contact with the lower surface of a static electrode; and the upper surface of the static electrode is in contact with a power supply output port. Through adoption of an optimized transmission ratio structure, a function of switching off the power supply after reaching a life limit can be realized; the power supply is only input and cannot be output; and the lightning protection box is scraped forcibly. The mechanical self-destruction lightning protection box is simple in structure and high in cost performance, and the use of waste and overdue products is well avoided.
