Description

Electrical obstacle detection device and a helmet equipped with the same {APPARATUS FOR DETECING ELECTRICAL OBSTACLES AND SAFETY HELMET INCLUDING THE SAME}

The present invention relates to an electrical obstacle sensing device and a hard hat having the same, and to an electrical obstacle sensing device for an electric worker and a hard hat having the same.

Workers at industrial sites, construction sites and other work sites must wear safety helmets. The hard hat is an equipment to protect the head of a worker in the event of a crisis situation such as the fall of various dangerous objects or the worker's fall at the work site.

In general, the hard hat is a hard outer housing and a headband fixed to wrap around the operator's head inside the outer housing, a cushioning material disposed inside the outer housing to absorb the shock applied from the outside of the outer housing so that it is not transmitted to the operator's head, and It is connected to the outer housing or the headband and is configured to include a wearing strap that prevents the hard hat from being arbitrarily separated from the worker by being tightened over the lower pipe of the worker.

On the other hand, electric workers have a different work site environment than a normal industrial site, and are characterized by a greater risk of electric shock than a risk of falling objects. However, the existing hard hat is mainly configured to reduce the impact applied to the worker's head, and the risk of electric shock is not considered.

In addition, in the case of electric workers who perform outdoor wiring work outside the building, they must frequently climb up and down the telephone pole, and at this time, accidents such as a fall may occur if the handle of the telephone pole is inadvertently held. Nevertheless, as a number of wires or transformers are arranged on the pole, electricians often climb the pole with their head raised and their view upwards to check electrical obstacles such as wires or transformers placed above the handle. many. This is likely to result in a fall of an electrician. In addition, there is a problem that work efficiency is lowered due to inability to concentrate on work due to electrical obstacles above the head that are difficult to visually check even after getting on the telephone pole.

In recent years, in addition to lighting equipment, the types of electric devices embedded in the indoor ceiling such as ceiling air conditioners are increasing, and various wirings are often located above the head of an electrician. Accordingly, there are frequent cases where the electrician must climb to the ceiling using a ladder or the like and perform various tasks. Even in this case, there is a problem that the electric worker has a risk of falling due to various electrical obstacles located on the head side as well as a problem of lower concentration on work.

Accordingly, there is a demand for an electric obstacle detecting device and a hard hat that can improve the safety of electric workers.

FIG. 1 is a perspective view of an electric obstacle detecting device for an electric worker and a hard hat having the same according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the hard hat shown in FIG. 1.

1 and 2, the hard hat for an electric worker according to the present embodiment includes an outer housing 110 and a headband 120, a cushioning material 130, a wearing strap 140, and an electrical obstacle detection device 200. Consists of including.

The outer housing 110 is generally implemented with a hard plastic or synthetic resin material, and absorbs an impact applied from the outside at a work site so that it is not directly applied to a worker.

The head band 120 is coupled to the inner side of the outer housing 110 and is formed to wrap the operator's head so that the operator can wear a hard hat. At this time, the head band 120 is coupled to be spaced apart from the inner surface of the outer housing 110 to prevent the impact applied to the outer housing 110 from being directly transmitted to the operator's head.

The cushioning material 130 is disposed inside the outer housing 110 together with the head band 120 so that the impact applied from the outside of the outer housing 110 is not transmitted to the operator's head. As shown in FIG. 2, the cushioning material 130 may be implemented in the form of a band that is coupled to the head band 120 and disposed so that the outer housing 110 is spaced apart from the inner side, for example, It may be formed of an absorbent material to be attached to the inner side of the outer housing 110. In addition, even when implemented in the form of a band, an additional shock absorbing material may be further disposed between the band and the inner side of the outer housing 110.

Meanwhile, the wearing strap 140 is generally combined with the head band 120 to fix the hard hat 10 together with the head band 120 to the operator's head. While the head band 120 wraps around the operator's forehead, the wearing strap 140 is hung to wrap around the lower pipe including the operator's chin, so that the hard hat 10 does not deviate from the operator's head even when the operator's posture changes. .

The electrical obstacle sensing device 200 may include an electrical obstacle sensing unit 210, an electric field sensing antenna 220, and a hard hat coupling unit 230.

The hard hat coupling unit 230 is a configuration for coupling and fixing the electric obstacle detection device 200 to the outside of the hard hat, and the electric obstacle detection unit 210 and the electric field detection antenna 220 of the electric obstacle detection device 200 are It should be stably fixed in a specific location outside of the machine.

In particular, in this embodiment, the hard hat coupling unit 230 may couple the electric obstacle detection device 200 to the hard hat so that the electric field detection antenna 220 extends from the front direction of the hard hat to the upper direction.

1 and 2 illustrate a case in which the hard hat coupling part 230 is configured in a band structure so that the electric obstacle detection device 200 can be easily detached from the hard hat, but the hard hat coupling part 230 is an electrical obstacle. The sensing device 200 may be configured in various structures capable of stably coupling the sensing device 200 to a designated position of the hard hat. For example, the hard hat coupling unit 230 may be implemented as a Velcro or the like that can easily attach and detach the electric obstacle detection device 200 from the hard hat, similar to the band structure, and the electric obstacle detection device 200 If it is not necessary to attach or detach from the hard hat, it may be implemented as an adhesive means to provide a more reliable bonding force.

The electric field detection antenna 220 is implemented as a conductor, is coupled to the electric obstacle detection unit 210, and is disposed at a predetermined position outside the hard hat together with the electric obstacle detection unit 210 by the hard hat coupling unit 230, and is directed. The electrostatic induction voltage generated by the electrical obstacle positioned in the direction is transmitted to the electrical obstacle detecting unit 210. That is, the electric field sensing antenna 220 functions as an antenna for transmitting a voltage induced according to the electrostatic induction principle to the electric obstacle sensing unit 210 according to the presence of an electrical obstacle in the directing direction.

Here, the electric field sensing antenna 220 corresponds to the head of the operator along the outer surface of the hard hat from the front direction of the hard hat, that is, the front wearing the hard hat, and the area above the eyes of the electric worker, as shown in FIGS. 1 and 2. It is arranged in a form that extends past the top. This is to enable the electrical obstacle detecting apparatus 200 of the present embodiment to easily detect an electrical obstacle existing in the upper portion of the front head of the electric worker.

As described above, when an electric worker performs a task, various electrical obstacles such as wires are often located above the worker's head, and the electric worker performs work on an electric line or electric device placed at a high position by using a ladder or a ladder. There are many cases where it is necessary to go up and down using a handle of a telephone pole or a special lifting vehicle manufactured for electric work. However, when an electrician climbs to a high position to perform a task, various electrical obstacles may exist in addition to the work target, and thus the electrician must be able to safely avoid the electrical obstacle.

Therefore, in the electric obstacle detecting device 200 of the present embodiment, the electric field sensing antenna 220 is disposed in a form extending beyond the top of the hard hat, so that electric obstacles existing above the head, which is the blind spot of the electric worker, are easily detected. To be able to do it.

Here, the electric field sensing antenna 220 is formed to pass from the front of the helmet, that is, from the forehead of the operator to the upper end, not only to detect electrical obstacles located in the front and upper portions of the electrician, but also due to the nature of humans. This is because most workers raise their head to look upward when going up. That is, even if the operator raises his head to a certain level, it is to be able to easily detect the electrical obstacles present above the operator.

Meanwhile, the electric obstacle detection unit 210 detects the presence of the electric obstacle by receiving and sensing a voltage induced to the electric field sensing antenna 220 by the electric obstacle. The electric obstacle detection unit 210 senses the voltage applied from the electric field detection antenna 220 and, if the level of the sensed voltage is higher than a predetermined reference voltage level, determines that an electric obstacle exists, and outputs a warning to the electrician. By doing so, it is possible for the electrician to avoid the danger caused by electric obstacles.

As a result, the electric obstacle sensing device 200 according to the present embodiment is arranged so that the electric field sensing antenna 220 extends from the front to the top of the helmet, so that the existence of the electric obstacle located in the upper direction of the electric worker is easy. By making it possible to recognize it visually, it is possible to avoid electrical obstacles located in the blind spot. In other words, it is possible to prevent an electric shock accident from occurring. In addition, when the electrician climbs a ladder or a telephone pole, it is possible to prevent a fall accident by allowing the electric worker to concentrate more on the handle or footrest of the ladder or telephone pole than on the electrical obstacle located at the top.

3 shows a schematic configuration of the electric obstacle detection unit shown in FIG. 2.

Referring to FIG. 3, the electric obstacle detecting unit 210 may include a voltage amplifying unit 211, a voltage determining unit 212, a control unit 213, an alarm unit 214, and a power supply unit 215.

The voltage amplifying unit 211 amplifies the voltage applied from the electric field sensing antenna 220 and transmits the amplified voltage to the voltage determining unit 212. In general, in the case of an electrostatic induced voltage induced to the electric field sensing antenna 220 by an electrical obstacle, the voltage level is very weak. Therefore, it is very difficult to check the existence of an electrical obstacle by using the voltage induced by the electric field sensing antenna 220 as it is. Accordingly, the voltage amplifying unit 211 amplifies the voltage from the voltage applied from the electric field sensing antenna 220 to determine whether an electrical obstacle exists and transmits the amplified voltage to the voltage determining unit 212.

The voltage determination unit 212 receives the amplified voltage from the voltage amplification unit 211 and determines a voltage level. The voltage determination unit 212 may measure the level of the amplified voltage, convert the measured voltage level into digital data, and transmit the measured voltage level to the control unit 213.

The control unit 213 compares the voltage level applied from the voltage determination unit 212 with a predetermined reference voltage level to determine whether an electrical obstacle exists. If the applied voltage level is greater than or equal to the reference voltage level, the control unit 213 drives the alarm unit 214.

The alarm unit 214 outputs a warning to the electrician according to the control of the control unit 213 so that the electrician can recognize the existence of an electric obstacle. In addition, the power supply unit 215 supplies power to each component of the electric obstacle detection unit 210. Here, the power supply unit 215 may be implemented as a rechargeable or replaceable battery, for example.

In the above, the voltage determination unit 212 and the control unit 213 have been described as separate configurations, but the voltage determination unit 212 may be included in the control unit 213 and implemented.

4 is a perspective view of an electric obstacle sensing device according to another embodiment of the present invention.

Hereinafter, with reference to FIG. 3, the electric obstacle detecting apparatus 300 illustrated in FIG. 4 will be described. In the electric obstacle detecting device 300 of FIG. 4, the electric obstacle detecting unit 310 and the hard hat coupling unit 330 have the same configuration as the electric obstacle detecting unit 210 and the hard hat coupling unit 230 of FIG. 3.

However, while the electrical obstacle sensing device 200 of FIG. 3 includes one electric field sensing antenna 220 extending from the front direction of the hard hat to pass through the top, the electrical obstacle sensing device 300 of FIG. 4 is the top of the hard hat. In addition to the electric field detection antenna 321 extending through the electric obstacle detection unit 310, two additional electric field detection antennas arranged in a form extending in both directions along the outer surface of the hard hat from the front direction of the hard hat ( 322).

In addition, the two additional electric field sensing antennas 322 may generate a static induction voltage by an electric field generated from an electric obstacle positioned in a direction in which each of the two additional electric field sensing antennas 322 is directed.

As the electrical obstacle sensing device 300 further includes two additional electric field sensing antennas 322 extending in both directions around the electrical obstacle sensing unit 310, the electrical obstacle sensing device 300 of FIG. 4 is an electric worker. Electrical obstacles located in the upper direction of the electrician's head as well as electrical obstacles located in both directions in front of the electrician can be detected and notified to the electrician. That is, it is possible to make the electric worker perceive electrical obstacles in more directions. At this time, the electric obstacle detection unit 310 can distinguish a location where an electric obstacle exists by distinguishing and discriminating the voltages induced from each of the electric field detection antenna 321 and the additional electric field detection antenna 322 from each other. According to this, different patterns of warnings can be output to the electrician. In other words, it can be warned so that the electric worker can immediately recognize the location of the electric obstacle.

The method according to the present invention can be implemented as a computer program stored in a medium for execution on a computer. Here, the computer-readable medium may be any available medium that can be accessed by a computer, and may also include all computer storage media.
