Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic diagram of an induction prevention apparatus according to an embodiment of the present invention. In fig. 1, the induction preventing device may include: the device comprises an upper end conductive unit 1, a commercial power electric shock protection unit 2 and a lower end conductive unit 3. The upper end conductive unit 1 is contacted with a human body and transmits induced electricity on the human body, and one end of the commercial power electric shock protection unit 2 is connected with the upper end conductive unit 1. One end of the lower end conductive unit 3 is connected with the other end of the commercial power electric shock protection unit 2, and the other end of the lower end conductive unit 3 is used for grounding. When the staff walks to high-voltage equipment below, the health produces the response electric charge, perhaps the human body also can produce the response static in daily life, and the response electricity is transmitted through the upper end conductive element 1 with human direct contact, and upper end conductive element 1 is on transmitting to commercial power electric shock protection unit 2 to transmit to ground through lower extreme conductive element 3. And then make the response electric charge on the staff's health release, avoid follow-up staff to contact and lead to the fact the damage with the conductor that ground switched on at the maintenance in-process. When a worker carelessly touches the voltage which is possibly and directly contacted by 220V mains supply and the like, the mains supply electric shock protection unit 2 limits the amplitude of the mains supply current to be in a range of breaking away from the current, and the mains supply electric shock protection unit 2 is rapidly fused, so that the upper end conductive unit 1 and the lower end conductive unit 3 are not conducted, meanwhile, the insulation property of the shoe enables the human body to be not conducted with the ground, and further the damage to the human body caused by the voltage which is possibly and directly contacted by the 220V mains supply and the like is avoided.
In one embodiment of the present invention, the specific structure of the commercial power electric shock protection unit 2 may be in various forms known to those skilled in the art, such as a current limiting fuse, a fuse, and the like. However, in a preferred example of the present invention, the specific structure of the mains shock protection unit 2 may be as shown in fig. 2, considering the design volume of the device and the simplicity of use. In particular, the mains shock protection unit 2 may comprise a fuse 20 and a resistor 21. One end of the fuse 20 is connected to the upper end conductive unit 1, one end of the resistor 21 is connected to the other end of the fuse 20, and the other end of the resistor 21 is connected to the lower end conductive unit 3.
When the human body of the worker generates induced electricity, the induced current is transmitted to the commercial power electric shock protection unit 2 along the upper end conductive unit 1, if the induced current does not exceed the fusing current of the fuse wire 20, the induced current flows to the resistor 21 along the fuse wire 20, is subjected to voltage division and current limitation by the resistor 21 and then flows to the lower end conductive unit 3, the induced current is transmitted to the ground by the lower end conductive unit 3, and the purpose of releasing the induced charge on the human body of the worker can be achieved through the process. When a worker inadvertently touches a voltage that may be directly touched by the 220V commercial power, etc., the 220V commercial power is also transmitted along the upper end conductive unit 1. When the 220V commercial power is transmitted to the commercial power electric shock protection unit 2, the resistor 21 limits the current transmitted by the 220V commercial power below the breaking current, so that the worker can break the voltage which may be directly contacted by the 220V commercial power and the like, and the current of the 220V commercial power exceeds the fusing current of the fuse 20, so that the fuse 20 is fused, and the upper end conductive unit 1 and the lower end conductive unit 2 are not conducted. Meanwhile, the shoes are self-insulating, so that the human body is not conducted with the ground, 220V mains supply cannot be conducted, workers are protected, and the harm to the human body due to mistaken electric touch is avoided.
In one embodiment of the present invention, fig. 3 is a schematic view of a peelable insulation cover of an induction preventing device according to one embodiment of the present invention, which further comprises a plurality of peelable insulation covers 7. The strippable insulating sleeves 7 are sequentially sleeved on exposed circuits among the upper end conductive unit 1, the commercial power electric shock protection unit 2 and the lower end conductive unit 3. The peelable insulating sheath 7 can be sleeved according to the length of the exposed lead. For adjusting the length of the total insulation package. The exposed lead is prevented from mistakenly touching the human body or other conductive objects.
In one embodiment of the present invention, the specific structure of the upper end conductive unit 1 may be in various forms known to those skilled in the art, such as a metal sheet, a conductive patch, and the like. In a preferred example of the present invention, the upper end conductive unit may include a conductive cloth 10 in consideration of convenience and safety of use, and the conductive cloth 10 may be cut in a circular shape in consideration of beauty and convenience of use. One side of the conductive cloth 10 can be coated with a conductive adhesive sticker to adhere the conductive cloth 10 to the inner side of the footwear, and the side without the conductive adhesive sticker is in contact with a human body, so that the transfer and release of induced current are facilitated.
In one embodiment of the present invention, the upper end conductive unit 1 may include a structure as shown in fig. 5 in consideration of the comfort of the worker using the apparatus. Specifically, in fig. 5, the upper end conductive unit 1 may include a conductive cloth 10. The conductive cloth 10 may be used to contact a human body. In view of the characteristic that the conductive cloth 10 can be arbitrarily bent and folded, the conductive cloth 10 can be cylindrically wound on the human body, thereby connecting the utility power electric shock protection unit 2 to the human body. Due to the structure of the conductive cloth shown in fig. 5, when the upper end conductive unit 1 is connected to the human body, no additional fixing mechanism is needed, which reduces the complexity of connection on one hand and reduces the burden of the upper end conductive unit 1 on the human body on the other hand.
In one embodiment of the present invention, as shown in fig. 4, the lower conductive unit 3 may include an aluminum foil 30. One side of the aluminum foil 30 may be coated with a non-setting adhesive to adhere the aluminum foil 30 to the shoe sole, so that a person can directly realize the connection of the lower end conductive unit 3 to the ground while standing. Further, considering that the standing posture of a person may affect the stability of the ground connection, the aluminum foil 30 may be shaped in a sole shape, thereby avoiding the problem of unstable connection due to the standing posture.
In one embodiment of the invention, the lower conductive unit 3 may comprise a conductive shoe cover 6, in view of comfort and versatility in preventing the use of an inductive electric device. The shape of the conductive shoe cover 6 can be similar to that of the shoe body, so that the conductive shoe cover can be stably sleeved on the periphery of the shoe body. Further, in order to facilitate the conductive shoe cover 6 to be sleeved on the periphery of the shoe body, the open side of the conductive shoe cover 6 may be an elastic mechanism. Although the material of the conductive shoe cover 6 can be various kinds known to those skilled in the art, in a preferred example of the present invention, the conductive shoe cover 6 can be made of conductive cloth 10 in consideration of the comfort and the aesthetic property of the shoe cover. The conductive shoe cover 6 is connected with the other end of the resistor 21. When the worker needs to use the conductive shoe cover 6, the opening side of the conductive shoe cover 6 is pulled open, the foot is put in along the opening side, the opening side is released after the placement is completed, the opening side of the conductive shoe cover 6 with the elastic function is automatically contracted, and then the conductive shoe cover 6 can be fixed. The use of different workers can be satisfied through the conductive shoe cover 6 with the elastic function. On the contrary, when the worker needs to take off the conductive shoe cover 6, the opening side of the conductive shoe cover 6 is slightly pulled open with force, so that the conductive shoe cover 6 can be separated from the shoe body, and the use and the disassembly are simpler and more convenient. The conductive shoe cover 6 can cover the sole side of the shoe body, so that a worker can stably contact the ground when moving, and the release of the induced electricity is facilitated.
In one embodiment of the present invention, the induction preventing means may further include a catch 4. As shown in fig. 3, 4 and 5, the buckle 4 may be sleeved outside the commercial power electric shock protection unit 2, and the other end of the buckle may be fixed to the upper, so as to fix the commercial power electric shock protection unit 2 to the upper.
When a worker accidentally touches a voltage such as 220V commercial power which may be directly touched, the voltage such as 220V commercial power is transmitted to the fuse 20 through the conductive cloth 10, and the current flowing through the fuse 20 at this time exceeds the fusing current of the fuse 20, so that the fuse 20 is fused. High temperature is generated in the process of fusing the fuse 20, and if the fuse 20 is in direct contact with the skin of a worker, the worker can be scalded; if the fuse 20 is in direct contact with the clothing of the worker, the clothing of the worker may be damaged. The body and clothes of the worker can be protected by the buckle 4, and when the fuse 20 is fused, the high temperature generated by fusing is isolated by the buckle 4. Meanwhile, the buckle 4 is easy to detach, and when the fuse wire 20 is fused, the fuse wire 20 can be conveniently detached and installed again.
In one embodiment of the invention, the line connecting the upper end conductive unit 1 and the mains shock protection unit 2 may comprise a retractable wire. Through this scalable wire, can make this prevent that induction system can adapt to the connection under the different operating mode conditions. For the specific structure of the retractable wire, there are many ways known to those skilled in the art, such as a conductive spring 5 as shown in fig. 5. In this fig. 5, the conductive spring 5 is connected between the upper end conductive unit 1 and the commercial power electric shock protection unit 2, so that when the worker needs to adjust the upper end conductive unit 1, the conductive spring 5 can be elastically deformed according to the position of the upper end conductive unit 1.
By combining and comparing various embodiments of the present invention, in a preferred example of the present invention, the upper end conductive unit 1 may be a conductive cloth 10, and the conductive cloth 10 may be made into a circular patch to be in contact with a human body or wound on the human body in a cylindrical shape according to the needs of a worker. The mains shock protection unit 2 may be composed of a fuse 20 and a resistor 21, and the mains shock protection unit 2 composed of the fuse 20 and the resistor 21 may be disposed in the buckle 4. The lower conductive element 3 may be an aluminium foil 30 and a conductive shoe cover 6.
According to the technical scheme, the device for preventing the induction provided by the invention, the induced electricity on the human body is transmitted to the lower end conductive unit along the commercial power electric shock protection unit through the upper end conductive unit, and finally the induced electricity is transmitted to the ground through the lower end conductive unit, so that the release of the induced charges of the human body is realized; when a human body unfortunately touches the mains supply, the mains supply electric shock protection unit limits the current of the mains supply and fuses in time, so that continuous damage caused by electric shock is avoided, and the human body is protected.
