Abstract

The present invention is a surveillance camera used in a dangerous area in an industrial surveillance camera, and is manufactured with a pressure resistant and dustproof structure. In the structure having a camera housing alone which can mount only a camera, The object can not be detected at a distance that can not be detected by the eyes, and the visual field may be obscured due to fogging or frost on the surface of the glass reinforced glass due to the difference between the inside and outside temperature of the product. In order to solve this problem, in addition to a camera housing with a camera only, an additional housing of a camera auxiliary device capable of mounting an IR lamp, an LED, or a thermal camera can be manufactured. You can also monitor distant objects over distances. Also, by attaching a heating pad to the inside of the tempered glass of the front part of the camera housing through which the light is transmitted, it is possible to obtain a clearer image by removing fogging or frost caused by temperature difference on the outer surface of the tempered glass.

Description

[0001] The present invention relates to an explosion-proof camera and a dust-proof explosion-proof camera,

This design is intended to secure normal surveillance images even in the external environmental influences such as the amount of light and the temperature in monitoring the images in the explosion proof camera of the internal pressure dust installed in the dangerous area. A housing such as a camera housing capable of mounting an auxiliary device is added to form an arm structure. On the inner surface of the glass housing front surface, a heating pad capable of preventing fogging or frost caused by temperature difference is attached Technology.

As the industry has grown, industrial facilities have become larger and diverse, and the use of hazardous materials has been continuously increased, which in turn increases the risk of fire and explosion. Therefore, in order to prevent the damage caused by fire and explosion, it is important to prevent the accident by predicting the risk from the stage of equipment installation and taking measures against it. For this reason, domestic and international safety standards have been established and regulated.

The present invention relates to a camera for industrial security surveillance, which can be used in a hazardous area designated by an IEC (International Electrotechnical Commission International Standardization Conference) such as an oil plant and a liquefied gas, a petrochemical complex, a flour mill or a North American Classification of Hazardous Locations (NEC) Is a surveillance camera used in the camera to protect the internal electrical devices from damage due to various reasons such as spark or explosion. It is a camera that has a structure that blocks it from the outside.

In general, an industrial pan / tilt camera includes a body portion a, a portion b rotating in the lateral direction (the body may rotate), and a portion c rotating in the vertical direction. And an electric device such as a motor is mounted inside. The AC / DC power supply is supplied from the outside, and the internal motor is driven through the electronic circuit, so that the housing can be controlled to rotate up and down and left and right. The actual video monitoring part includes a camera housing c) The camera is mounted inside the unit. This camera converts the light of an external subject incident through a lens into an electric signal through a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) using a supplied power source and outputs this signal to an external recording device If you convert it to a video through a video output device like a monitor, you can see it on the screen.

In this case, the subject to be monitored is usually turned into an electrical signal, and in the process of being converted into a video signal, the outside environment may not always be able to display a clear image as we see with the eyes. On the other hand, You can even watch what you do not see. In order to accomplish this, a camera device as well as a device capable of complementing and improving the device are needed. In order to operate the additional device simultaneously with the camera device, the product is designed to have a structure with a high pressure resistance and a dustproof structure. There is a purpose of.

The present invention is based on the idea that an explosion proof camera having only a camera housing portion can not identify an object because there is not enough light in an external environment or can not detect a subject at a remote place that can not be detected by a human eye, If there is fogging or frost on the surface of the tempered glass surface of the camera housing due to the difference, it is difficult to obtain a normal monitoring image.

According to an aspect of the present invention, there is provided a camera housing for a camera, comprising: a housing for mounting an additional camera auxiliary device; a housing for housing the camera; . At this time, the camera housing part and the camera auxiliary device housing part are connected to each other by a sun shield bracket which can prevent external radiant heat, so that they can be moved at the same time. All housings are made of austenitic stainless steels such as SUS316, SUS316L, and SUS304. All housings do not include welding and are more suitable for internal pressure and dust explosion.

According to the present invention, there is provided a camera for detecting an IR lamp or an LED in a camera auxiliary apparatus housing, as well as a camera such as a thermal imaging camera, in an explosion-proof area, Since the auxiliary device can be mounted, it is possible to obtain more clear and various surveillance images. As the heating pad attached inside the tempered glass, there is a possibility that the surveillance image There is an effect of solving the effect of interfering with.

The present invention will now be described in detail with reference to the accompanying drawings.

A fan motor and a drive capable of rotating the tilt housing 101 as an upper body are mounted on the base housing 100 as a lower body and the tilt housing 101 is rotated to be rotatable with the tilt housing 101 as an upper body And is connected to the rotation axis 106. Similarly, the tilt housing 101 is provided with a tilt motor capable of rotating the camera housing 102 up and down and a built-in circuit for controlling the tilt motor. The camera housing 102 is connected to the tilt housing 101 via the rotation shaft 107 do. At this time, there is a camera housing cover 105 with a front tempered glass to which a light of a subject enters from the camera housing part. The camera housing cover 105 is detachably attached to the front tempered glass part 108, and a heating pad 109, which can prevent fogging or frost, . 3, the camera auxiliary housing 103 is connected to the camera housing 102 so as to operate at the same time, and the sunshield bracket (sunshield bracket) 104 are installed to complete all the configurations as shown in FIG. The completed configuration serves as an internal pressure and dust explosion proof camera, and also includes an IR lamp mounted inside the camera auxiliary housing 103 on the opposite side that operates together with the camera housing 102 in a dark external environment without light, Or a thermal image camera to obtain a clear and various surveillance image. In addition, since the heating pad 109 attached to the inside of the glass reinforced glass front part has a temperature It is possible to solve the effect of disturbing surveillance such as fogging or frost caused by the difference.
