Technical Field
The utility model relates to an electric shock prevention device technical field specifically relates to a rainy season protection against electric shock and alarm device.
Background
The rainfall is concentrated in summer every year, and the urban drainage facilities are difficult to drain the rainfall in a short time, so that the accumulated water can be formed in the city. In the city, because low-voltage electrical equipment is numerous at present, most users do not have electrical professional knowledge, and equipment leakage is easily caused by equipment damage, aging and the like. Rainwater is not pure water, and impurities mixed in the water can make the rainwater become a good conductor of electricity. Once the pedestrians walk into the electrified water body, personal casualty accidents are very likely to happen, and in recent years, the unfortunate accidents that the pedestrians get electric shock and die in the electrified water body occur every summer.
For example, as shown in fig. 1, when a live wire in a power supply system falls into rainwater due to damage or the like, the ground point has the same potential as the live wire, and current flows away from the ground point of the live wire into the rainwater, so that a potential distribution area is formed on the ground with the ground point as the center, and the farther away from the ground point, the more the current is distributed, and the lower the ground potential is. If a person stands near a place far away from an electric wire grounding point, when the person walks off the feet, electromotive force is generated between the two feet due to the resistance between the two feet, although current flows along the lower part of the person and does not pass through important organs of the human body, when the person is acted by higher voltage, the two feet can twitch, and the body falls on the ground. This will change the path of the current through the body and may flow through vital organs of the body, causing casualties.
Of course, the method of putting through the insulating boot can be adopted to prevent people from electric shock casualties in the electrified water body. But the insulating boot is very heavy to wear, and the heavy insulating boot is very uncomfortable to wear in summer. Meanwhile, the insulating boot is a rubber product and is easily aged by oxidation, illumination and the like, so that the insulating property is reduced until the insulating boot loses the effect completely. In professional electric power departments, the insulating boots can be periodically checked to detect whether the requirements of insulating performance can be met, but the ordinary families cannot do the same, because the cost of the checking is high and the time is long, and in addition, the regular replacement of the insulating boots can bring about not less economic pressure to the ordinary families.

Detailed Description
In order to avoid the personnel to miss and cause the electric shock casualty condition in going into electrified water, the utility model provides a rainy season protection against electric shock and alarm device, please see and show that figure 2 shows, the device mainly comprises device constitutional unit and detection module unit 10, and device constitutional unit mainly includes receiving antenna 5, two sets of conductive fabric 20 and shoes 30, and conductive fabric 20's both ends are connected with receiving antenna 5, shoes 30 respectively.
The conductive fabric 20 is soft and convenient to store, when the rainfall is predicted to possibly occur and an electric shock prevention and alarm device needs to be used, but when the conductive fabric is not used temporarily, the conductive fabric 20 is convenient to be placed in a backpack, a schoolbag, a pocket and the like for storage, and is taken out for use when the conductive fabric needs to be used.
The two ends of the conductive fabric 20 are both provided with conductive connecting buckles 40, the conductive connecting buckles are also made of conductive fabric, and can be assembled with the conductive fabric 20 in an integrated or detachable connection mode (such as thread gluing and the like), and can be conveniently and closely connected with the loop buckles on the shoe 30 and the loop buckles of the receiving antenna 5, and also can be conveniently taken down.
The shoe 30 can be made into any style according to the use requirement of the user, and can be a sports shoe, a sandal, a slipper and the like, and the surface of the shoe is covered by a conductive fabric layer.
Referring to fig. 3, the detection module unit 10 mainly includes a receiving antenna 5, an a/D converter 1, a single chip microcomputer 2, a buzzer 3, and a battery 4 for supplying power to the components.
