Description

Technical Field

[0001] The utility model relates to the technical field of monitoring cameras, in particular to a protective video monitoring camera. Background Art

[0002] Cameras generally have basic functions such as video recording, transmission and static image capture. After the lens collects the image, the photosensitive component circuit and control component in the camera process the image and convert it into a digital signal that can be recognized by the computer. It is then input into the computer through a parallel port or USB connection, and the software restores the image. Surveillance cameras are an important part of the security system. It is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuitive, accurate, timely and rich information content.

[0003] In the prior art, conventional video surveillance cameras are mostly installed outdoors. During use, the lens assembly cannot be telescoped and adjusted according to the light intensity. For example, in direct light or rainy and snowy weather, the light at the lens is poor and the picture is not clear. In a high temperature environment, simply opening heat dissipation holes cannot meet the heat dissipation needs of the camera, and dust and rainwater are easily allowed to enter, damaging the internal electrical components. In a low temperature environment, the temperature difference between the lens assembly and the external air causes the lens assembly to fog, resulting in blurry pictures taken by the lens assembly, which is not conducive to use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model discloses a protective video surveillance camera, comprising a shell 1, a baffle 2 is fixedly installed on the upper surface of the shell 1, a moving mechanism 3 is fixedly installed on the upper and lower inner walls of the shell 1, a rectangular box 4 is fixedly installed on the right side of the moving mechanism 3, and a rubber sealing ring 5 is fixedly installed on the inner walls of the shell 1 around the corresponding rectangular box 4, the rectangular box 4 is movably inserted on the right side wall of the shell 1, a mounting hole 6 is opened on the left side wall of the rectangular box 4, a lens assembly 7 is embedded in the right side wall of the rectangular box 4 corresponding to the mounting hole 6, a control assembly 8 is fixedly installed on the left side of the lens assembly 7, a defogger mechanism 9 is installed on the right side wall of the rectangular box 4, a rectangular opening 10 is opened on the left side wall of the shell 1, a sealing cover 11 is installed on the left side of the shell 1 corresponding to the rectangular opening 10, a cooling mechanism 12 is arranged on the sealing cover 11, and an air intake mechanism 13 is arranged on the lower side wall of the shell 1.

[0022] Specifically, the moving mechanism 3 includes an electric linear module 301, a connecting sleeve 302 and a light sensor 303. The electric linear module 301 is fixedly installed on the inner wall of the shell 1. The connecting sleeve 302 is fixedly installed on the right side of the slide of the electric linear module 301. The right side of the connecting sleeve 302 is fixedly connected to the left side of the rectangular box 4. The light sensor 303 is embedded in the right side wall of the rectangular box 4 before and after the lens assembly 7.

[0023] In this embodiment, the light sensor 303 detects the light intensity at the lens assembly 7. When the light at the lens assembly 7 is not good, the information is fed back to the control component 8. The control component 8 causes the electric linear module 301 slide to drive the connecting sleeve 302 to move to the right. The connecting sleeve 302 drives the lens assembly 7 to move to the right through the rectangular box 4, so that the folding area of ​​the baffle 2 to the lens assembly 7 is smaller, thereby improving the light intensity. Conversely, when the light at the lens assembly 7 is too bright, the information is fed back to the control component 8. The control component 8 causes the electric linear module 301 slide to drive the connecting sleeve 302 to move to the left. The connecting sleeve 302 drives the lens assembly 7 to move to the left through the rectangular box 4, so that the folding area of ​​the baffle 2 to the lens assembly 7 is larger, thereby improving the external light intensity and ensuring better quality of the captured image.

[0024] Specifically, a limit block 14 is fixedly installed on the right end of the lead screw of the electric linear module 301 .

[0025] In this embodiment, the limit block 14 prevents the slide of the electric linear module 301 from falling off the lead screw, so that the lens assembly 7 on the rectangular box 4 can move left and right stably.

[0026] Specifically, the defogger mechanism 9 includes a micro exhaust fan 901, an air inlet pipe 902, an air outlet pipe 903, an air distribution box 904 and an air outlet head 905. The micro exhaust fan is installed on the upper inner wall of the rectangular box 4. The air inlet pipe 902 is installed on the air inlet of the micro exhaust fan 901, and the air outlet pipe 903 is installed on the air outlet of the micro exhaust fan 901. The air outlet pipe 903 is fixedly connected to the air distribution box 904. The air distribution box 904 is fixedly installed on the right side of the rectangular box 4 corresponding to the upper side of the lens assembly 7, and the air outlet heads 905 are evenly arranged on the lower surface of the air distribution box 904.

[0027] In the present embodiment, the external temperature of the shell 1 is detected by the cooling mechanism 12. When the external temperature is lower than the set value, the information is fed back to the control component 8. The control component 8 enables the micro exhaust fan 901 to draw the gas in the shell 1 into the air inlet pipe 902 through the air inlet pipe 902. Since the control component 8 is arranged in the shell 1, the control component 8 will generate heat. Therefore, the temperature in the shell 1 is relatively high. The hot air flows into the air distribution box 904 and is blown to the lens assembly 7 through the air outlet head 905 on the lower surface of the air distribution box 904, so that the lens assembly 7 will not fog.

[0028] Specifically, the temperature reduction mechanism 12 includes a semiconductor refrigerator 121 and a temperature sensor 122 . The semiconductor refrigerator 121 is embedded in the sealing cover 11 corresponding to the rectangular opening 10 , and the temperature sensor 122 is embedded and installed on the housing 1 .

[0029] In this embodiment, the temperature sensor 122 detects the temperature outside the shell 1. When the temperature is greater than the set value, the information is fed back to the control component 8. The control component 8 enables the semiconductor refrigerator 121 to start cooling and cool the inside of the shell 1.

[0030] Specifically, the air intake mechanism 13 includes a threaded sleeve 131, a filter cartridge 132 and a one-way air intake valve 133. The threaded sleeve 131 is fixedly installed on the lower side wall of the shell 1. The filter cartridge 132 is installed on the inner thread of the threaded sleeve 131, and the lower surface of the filter cartridge 132 is an open structure. The one-way air intake valve 133 is installed on the upper surface of the filter cartridge 132.

[0031] In this embodiment, the threaded sleeve 131 installs the filter cartridge 132, and the filter cartridge 132 allows the external air to enter the shell 1 after being filtered. The one-way air intake valve 133 prevents the air from flowing back in the shell 1, so that the air pressure in the shell 1 remains balanced.

[0032] When in use, the light intensity at the lens assembly 7 is detected by the light sensor 303 in the moving mechanism 3. When the light at the lens assembly 7 is not good, the information is fed back to the control component 8. The control component 8 makes the electric linear module 301 slide to drive the connecting sleeve 302 to move right. The connecting sleeve 302 drives the lens assembly 7 to move right through the rectangular box 4, so that the folding area of ​​the baffle 2 to the lens assembly 7 is smaller, and the light intensity is improved. On the contrary, when the light at the lens assembly 7 is too bright, the information is fed back to the control component 8. The control component 8 makes the electric linear module 301 slide to drive the connecting sleeve 302 to move left. The connecting sleeve 302 drives the lens assembly 7 to move left through the rectangular box 4, so that the folding area of ​​the baffle 2 to the lens assembly 7 is larger, the external light intensity is improved, and the quality of the captured picture is better. The device 122 detects the temperature outside the shell 1. When the temperature is greater than the set value, the information is fed back to the control component 8. The control component 8 enables the semiconductor refrigerator 121 to start cooling and cool down the shell 1. The temperature sensor 122 detects the external temperature of the shell 1. When the external temperature is lower than the set value, the information is fed back to the control component 8. The control component 8 enables the micro exhaust fan 901 in the defogger mechanism 9 to draw the gas in the shell 1 into the air inlet pipe 902 through the air inlet pipe 902. Since the control component 8 is arranged in the shell 1, the control component 8 will generate heat. Therefore, the temperature in the shell 1 is relatively high. The hot air then flows into the air distribution box 904 and is blown to the lens assembly 7 through the air outlet head 905 on the lower surface of the air distribution box 904, so that the lens assembly 7 will not fog up and the lens assembly 7 will be avoided from being blocked by fog, thereby ensuring clear shooting pictures and facilitating use.

[0033] To sum up, this protective video surveillance camera can adjust the telescopic length of the lens assembly 7, so as to achieve the effect of adjusting the intensity of the light blocked by the lens assembly 7, so as to achieve a better shooting effect. At the same time, it can improve the heat dissipation performance, effectively prevent the entry of external dust and rainwater, increase the defog function of the lens assembly 7, ensure that the shooting picture is clear, and facilitate use.
