Ventilation system of video monitoring device

Abstract

The invention relates to a ventilation system of a video monitoring device. The ventilation system comprises a shell. A window is installed at one end of the shell. An exhaust port is formed in the portion, below the window, of the shell. A ventilation cover is hinged to the lower end of the exhaust port. The ventilation cover is controlled by a driving mechanism installed inside the shell to be opened or closed. The driving mechanism is controlled by a control circuit unit installed inside the shell to act. According to the ventilation system of the video monitoring device, the purpose of driving a wiper and the purpose of controlling the ventilation cover to be opened or closed according to the interior temperature of the video monitoring device can be achieved through a single motor, so that the requirements that sealing and heat preservation be realized in winter and ventilation and heat dissipation be realized in summer are effectively met. The ventilation system of the video monitoring device is simple in structure, scientific and reasonable in design and low in cost; he purpose of driving the wiper and the purpose of controlling the ventilation cover to be opened or closed according to the interior temperature of the video monitoring device can be achieved through the single motor, so that the requirements that sealing and heat preservation be realized in winter and ventilation and heat dissipation be realized in summer are effectively met, and the performance of the video monitoring device is effectively improved.

Description

technical field [0001] The invention belongs to the field of video security monitoring and relates to a ventilation system of a video monitoring device. Background technique [0002] In order to meet the diverse needs of the market, the existing video surveillance devices must meet the requirements of sealing and heat preservation in winter and the requirements of ventilation and heat dissipation in summer, which are usually contradictory. If the video monitoring device is designed with high sealing performance, it can have a good heat preservation effect in winter and is rainproof and dustproof. The hot air cannot be discharged, and the heat dissipation effect is not good. Because the internal heat cannot be dissipated, the camera installed in the video surveillance device cannot work normally. [0003] In addition, especially in the cold winter, due to the large temperature difference between the inside and outside of the window of the video surveillance device, fogging i...

Problems solved by technology

If the video monitoring device is designed with high sealing performance, it can have a good heat preservation effect in winter and is rainproof and dustproof. The hot air cannot be discharged, and the heat dissipation effect is not good. Because the internal heat cannot be dissipated, the camera installed in the video surveillance device cannot work normally.

[0003] In addition, especially in the cold winter, due to the large temperature difference between the inside and outside of the window of the video surveillance device, the inside of the window is prone to fogging, which seriously affects the image monitoring effect.

[0004] Furthermore, when the waterproof performance of the video surveillance device is poor, once rainwater invades the interior of the video surveillance device, since it cannot be discharged, the electrical equipment such as the camera in it will be immersed and damaged.

[0005] Through the search, no effective technical means have been found to solve the video surveillance device that not only ensures the sealing performance, but also has strong ventilation performance.
