Description

A high voltage warning device

technical field

The utility model relates to the field of warning devices, in particular to a high-voltage warning device.

Background technique

With the continuous development of power grid construction, long-distance power transmission has become a strategic project that affects regional economic development. In the process of power transmission, high-voltage lines are generally used for transmission, such as 110KV, 220KV, 330KV and 500KV and other high-voltage lines. At present, the highest AC voltage transmission level in my country has reached 1000kV. Although the high-voltage line facilitates the transmission of electric energy and greatly reduces the loss of electric energy, it brings potential high-voltage danger, because electric shock accidents caused by high-voltage lines occur frequently.

In order to reduce possible electric shock accidents near the high-voltage power grid, people have adopted many warning methods, such as hanging warning signs or using light display signs. Ignored by people, when people approach this type of warning sign from far to near, the fatigue of the perspective and the characteristics that people are not easy to pay attention to static objects will easily lead to safety accidents, and its warning effect has limitations. For this reason, it has been proved that the method of camera warning and electromagnetic field induction warning, and manual warning through camera can not improve the warning effect in actual use, and it is labor-intensive, but there is electromagnetic interference through electromagnetic field induction warning. When electromagnetic induction is used to judge whether someone or something is approaching, the high voltage of the high-voltage line itself will generate a high-voltage electric field, which will affect the actual judgment result of electromagnetic induction and cause false alarms. Therefore, relying only on electromagnetic induction, its reliability is also high. Not guaranteed.

Utility model content

The purpose of the utility model is to provide a high-voltage warning device, which solves the problem that the warning effect of the high-voltage warning device in the prior art is not obvious enough, and realizes the purpose of giving a strong warning to personnel entering a dangerous area.

The utility model is realized through the following technical solutions:

A high-voltage warning device, comprising a base, a column, and an LED warning board, the column is arranged on the base, the LED warning board is fixed on the column, and the column is also provided with a thermal infrared human body sensor, a strong light Light, voice warning device, control module, described control module is connected with described LED warning board, thermal infrared human body sensor, strong light, voice warning device respectively. Aiming at the limited warning effect of the existing high-voltage warning device, the utility model discloses a device that uses a strong light to warn people entering a dangerous area. The LED warning board flashes to achieve the purpose of giving a strong warning to the personnel entering the dangerous area. During the working process, the LED warning board remains on, and the words such as "high voltage danger" are set in advance, and the thermal infrared human body sensor continuously detects the space ahead. The sensor can immediately know and transmit the signal to the control module, and the control module sends instructions to the connected LED warning board, strong light, and voice warning device, and the warning words on the LED warning board flash , the strong light is powered on, and the voice warning device emits a warning sound, so as to suddenly and dynamically stimulate the visual and auditory senses of the personnel entering the dangerous area, so as to improve the warning effect. When the person leaves the detection range of the thermal infrared human body sensor, the control module sends an instruction again, the strong light is turned off, the voice warning device stops sounding, and the LED warning board stops flashing and returns to the normal point In the bright state, all warning devices return to normal.

Further, several strong lights are connected in parallel. Multiple bright lights are turned on at the same time to improve the visual warning effect.

Further, the illumination direction of the strong light is obliquely facing the ground. The light emitted by the strong light is stronger and has better transmission. In order to avoid interfering with the sight of people coming directly ahead, the direction of illumination of the strong light is tilted towards the ground.

Further, a shield is provided on the top of the upright, and the width of the shield is larger than that of the upright. The high-voltage warning devices are mostly installed in open-air environments, and the shades are installed to protect the equipment from the sun and rain, so as to reduce the possible damage to the equipment caused by exposure to the sun or rain.

To sum up, compared with the prior art, the utility model achieves the purpose of strongly warning people who enter the dangerous area through the stimulation of the vision when the strong light is turned on instantaneously, plus the sound alarm and the flashing of the LED warning board.
