Description

Monitor device

Technical Field

The present invention relates to a monitor device suitable for industrial environment, and more particularly to a monitor device which can make the overall volume of the monitor more compact and simple than the existing similar products, and can drive three photoelectric devices to rotate synchronously in a first direction and/or a second direction.

Background

With the progress of society and the development of science and technology, monitors have become a part of daily life and are widely installed in various places such as traffic intersections, homes, businesses, offices, factories, and the like to monitor the environment and prevent potential accidents.

Because most of monitors are arranged outdoors, the monitors are exposed to the sun and rain and blown by the wind and rain when being used outdoors for a long time, the monitors are easy to corrode and damage, and outdoor wind sand, dust or other dirty dirt is easy to accumulate in gaps or lenses, thereby influencing the use of the monitors. In a high-grade industrial monitor applied in a severe environment, it is also required to have an explosion-proof performance so as to prevent the monitor from being damaged when a strong explosion occurs in the field of the industrial environment, thereby protecting the image acquired by the monitor. Therefore, in high-grade industrial monitor devices, the monitor is generally disposed in a protective housing to prevent the monitor from being directly exposed to sunlight and rain, damaged by human beings, or strongly exploded by the environment.

In order to monitor the surrounding environment to the greatest possible extent, most monitors have the function of being rotatable in the horizontal direction and in the vertical direction, and in order to be able to acquire clear images at night or in poorly lit environments, some monitors are equipped with both a camera and an infrared thermal imager (collectively referred to as "optoelectronics"). For example, in a conventional monitor, a camera and a thermal infrared imager are arranged in a transparent glass cover, however, since infrared rays are reflected and refracted by the glass cover when being projected outwards in the glass cover to affect the acquisition of the camera, the glass cover of the monitor is usually made of germanium glass in order to reduce the adverse effect; however, the hardness and strength of germanium glass cannot meet the stringent industrial explosion-proof standards.

In order to solve the above problems, a conventional monitor equipped with two types of optoelectronic devices, such as a camera and a thermal infrared imager, is configured such that the two types of optoelectronic devices are disposed on opposite sides of the exterior of a housing of the monitor, and the housing is driven to rotate in a horizontal direction and the two types of optoelectronic devices are driven to rotate in a vertical direction by a transmission mechanism disposed inside the housing, as shown in, for example, chinese patent No. CN 213817900U.

In addition to the two optoelectronic devices, it is practically necessary to provide a third optoelectronic device (e.g. wide-angle camera, telephoto camera, illumination lamp, 8230; etc.) at the same time on the monitor, but the provision of the third optoelectronic device and the synchronous rotation of the third and the first and the second optoelectronic devices inevitably make the whole mechanism bulky and complicated.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a monitor device that controls three electro-optical devices to rotate synchronously by a compact and simple transmission mechanism.

By means of the structure of the monitor, all mechanisms for driving the three photoelectric devices to synchronously rotate can be integrated and concentrated in the cylindrical shell, and the appearance of the whole monitor is simpler compared with that of the existing monitor.

Preferably, the first direction is a horizontal direction, and the second direction is a vertical direction.
