High-altitude advertisement apparatus convenient to mount and dismount

Abstract

The invention relates to an advertisement apparatus, particularly to a high-altitude advertisement apparatus convenient to mount and dismount. The advertisement apparatus comprises a support rod and an advertisement screen body arranged on the support rod. The high-altitude advertisement apparatus is characterized in that electromagnets are arranged at the upper end of the support rod; and magnetic blocks cooperating with the electromagnets are arranged at the advertisement screen body. The magnetic blocks cooperating with the electromagnets are arranged at the corresponding positions at the back of the advertisement screen body. An ultrasonic jammer and an angle steering device are arranged at the top of the advertisement screen body; and an infrared detection probe is arranged at the angle steering device and is connected with a controller of the ultrasonic jammer. A roller is arranged at the top of the support rod; and a motor is arranged at the lower part of the support rod. According to the apparatus provided by the invention, the potential mounting hazard caused by working high above the ground can be eliminated; the advertisement screen body can be replaced conveniently and rapidly; birds and mosquitoes can be driven away; and thus the liquid crystal display screen can be protected and the advertising effect can be guaranteed.

Description

technical field [0001] The invention relates to an advertising device, in particular to a high-altitude advertising device which is easy to assemble and disassemble. Background technique [0002] The high-altitude electronic advertising screen in the prior art usually includes a support rod and an electronic advertising screen fixed on the support rod. Usually, the support rod and the electronic advertising screen are fixedly connected by fastening bolts, which is inconvenient to operate.

[0002] The high-altitude electronic advertising screen in the prior art usually includes a support rod and an electronic advertising screen fixed on the support rod. Usually, the support rod and the electronic advertising screen are fixedly connected by fastening bolts, which is inconvenient to operate. Although During installation, the electronic advertising screen and the support rod can be fixed first, and then the support rod can be fixed on the ground. However, when it is necessary to disassemble and maintain, because the support rod has been fixed on the ground, it is necessary to climb up the support rod to fix the electronic advertising screen. The fastening bolts are disassembled to remove the electronic advertising screen. Due to the need for high-altitude operations, the risk factor is high

In addition, because the birds in nature will inhabit the electronic advertising screen, it is easy to cause damage to the LCD screen. In addition, because the LCD screen glows at night, it is easy to attract mosquitoes, which will affect the advertising.
