The present invention relates to an image surveillance apparatus having a dustproof apparatus, and more particularly, that the oil is leaked from the power generation equipment, or fire, mist is generated by installing in a power plant, which generates a lot of vibration and is not easily accessible to the inspection personnel. The present invention relates to an image surveillance apparatus having a dustproof apparatus that can be used to confirm early and can obtain a clear image by canceling or correcting vibration.

In general, since various equipments installed in a power plant are operated by oil of high pressure, various valves and pipes are arranged for the flow of oil, and high heat is generated around these various valves and piping systems. In addition, these power plants are generating a large vibration due to the nature of the equipment. Therefore, it is not easy for the inspector to access the facility in order to confirm the abnormality of the facility, and due to the nature of the location where the power generation facility is installed, it is difficult to secure the field of vision.

In particular, since the number of people who work in the power plant consisting of automated equipment is limited compared to the installation area, there is a point that it is difficult to always monitor all the facilities of the site in real time with a limited number of workers.

Therefore, it is difficult to detect oil leakage early when vibration occurs in a valve or piping system in which high pressure oil is being flowed. The oil leaked is ignited by surrounding high temperature because it is in a high temperature and high pressure state. There is a risk of fire.

If a fire leads to high-pressure oil and other surrounding conditions, it is difficult to access the site, making it difficult to initially extinguish, resulting in a large loss of power plant equipment.

Accordingly, the facility is photographed using a video surveillance device that provides a method and a security function, and the photographed image data is transmitted to the main surveillance system, where the administrator reads the image from the center and checks for abnormalities.

However, it is very difficult to obtain a good image with a video surveillance device that provides a normal security and security functions due to the vibration in a region where a lot of vibration is a risk of accidents, there is a problem that the continuous real-time constant monitoring is not normally performed.

Accordingly, the present invention has been proposed to solve the above problems, and an object of the present invention is to provide a vibration isolator capable of constructing a constant detection system of power plant equipment by obtaining a good image even when installed in a power generation facility that generates a lot of vibrations. The purpose is to provide a video surveillance market.

Preferably, the first vibration damping unit is formed of a plurality of springs, and the outer periphery includes a plurality of shock absorbers acting as a reaction force of the spring.

The secondary vibration attenuation unit is coupled to the moving base to detect the vibration of the movement base vibration sensor, attenuation vibration generator installed on the moving base, the attenuation vibration generator receives the signal detected by the vibration detection sensor It is preferable to include a control unit which controls to generate reverse vibration.

The damping vibration generator is coupled to the moving base and provided with a space therein and a pair of pillars on one side, an electromagnet disposed in the case and operated by the control of the control unit, the pillar of the case Elastic plate is coupled to, it is preferable to include a weight coupled to the center of the elastic plate.

The moving base is preferably coupled to a protective case for protecting the camera.

In the present invention, when the camera is installed in a facility of a power plant and the camera shakes due to the vibration of the facility, the vibration is first absorbed by the primary vibration attenuator and the reverse vibration is actively generated by the secondary vibration attenuator to cancel the vibration. In this way, the camera can be prevented from being shaken by the vibration, so that an image of the facility can be satisfactorily obtained. As such, by transmitting a good image obtained through the embodiment of the present invention to the main monitoring system, it is possible to easily build a regular monitoring system for a vulnerable area in which there is a risk of a power plant equipment accident.

Of course, the above-described display 51 is preferably installed in the main monitoring device provided in a separate place.

Referring to the operation of the embodiment of the present invention made in this way in detail as follows.

When the vibration is generated in the state where the video surveillance device having the vibration isolator of the embodiment of the present invention is installed in the facilities of the power plant is primarily absorbed by the primary vibration attenuator (3).

That is, when the vibration is transmitted to the spring 11, the vibration is absorbed, and the vibration is attenuated by the action of the shock absorber 13 when the compressed spring 11 is tensioned again. By repeating this process, the vibration acting on the moving base 5 (or a camera coupled to the moving base) is absorbed.

In the case where the vibration is continuously generated, the vibration sensor 21 detects the vibration of the moving base 5. The vibration sensor 21 transmits the detected vibration signal to the control unit 25. Then, the control unit 25 controls the reverse vibration to be generated in the damping vibration generator 23 to cancel the vibration.

That is, the damping vibration generator 23 is attached to the elastic plate 35 while the electromagnet has magnetic properties under the control of the control unit 25. Then, the weight 37 moves together with the reverse vibration. This reverse vibration thus causes the moving base 5 to remain stationary, and the camera 9 coupled to the moving base 5 also remains stationary.

Therefore, the camera 9 can photograph the facilities of the power plant without shaking and transmit a good video signal to the control unit 25. The control unit 25 transmits such an image signal to the display 41 so that the inspection personnel (or managers) can always monitor and monitor the power plant facilities in real time.
