Description

Technical Field

[0001] The utility model relates to a camera protection device, in particular to an installation protection device used for an outdoor camera. Background Art

[0002] A camera is a video input device with video recording and static image capture functions. It is widely used in video conferencing, telemedicine, and security monitoring. Cameras used for security monitoring are also called surveillance cameras. Surveillance cameras are divided into two categories: indoor and outdoor. Outdoor cameras are used in harsh environments. Long-term exposure to rain, dust, and sunlight will cause wear and tear on the camera lens. Rainwater infiltration will also cause damage to the camera. Therefore, outdoor cameras have higher requirements for waterproofing. Usually, protective devices are installed on the outside of the camera to increase the service life of the camera.

[0003] In the prior art, there are two types of protective devices for outdoor cameras, full protection and semi-protection. Semi-protection cameras generally use sealing rings and other seals to improve the waterproof level of the camera housing, and set a sunshade on the top of the camera. The sunshade is semi-integrated with the camera housing. This type of camera is suitable for installation under eaves, corridors and other places with less rain erosion. Full-protection cameras generally have a protective box installed on the outside of the camera, which is used to isolate the external erosion of rain and dust, and is suitable for use in any environment. However, since the external protection box of the fully-protected camera is sealed, the internal temperature is high in an environment with direct sunlight, which will affect the working life of the camera.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] See also Figures 1 to 6 This embodiment provides an installation protection device for an outdoor camera, including:

[0031] A protection compartment 1, the protection compartment 1 comprises a protection box 11, the protection box 11 is used to protect the camera 4, a waterproof component 2 is provided on the top of the protection box 11, and a heat dissipation device 3 is provided on the bottom of the protection box 11;

[0032] The protection box 11 is made of metal. A square through hole is provided on the front side of the protection box 11 . A light-transmitting plate 15 is pasted inside the front side of the protection box 11 . The light-transmitting plate 15 completely covers the through hole on the front side of the protection box 11 .

[0033] A partition plate 12 is welded to the bottom of the protection box 11 , a sliding plate 13 is welded to the bottom of the protection box 11 , and air holes 14 are provided on both sides of the top of the protection box 11 .

[0034] A mounting bracket 17 is welded to the middle of the bottom surface of the sliding plate 13, and a bracket base 18 is connected to the bottom of the mounting bracket 17 by bolts. The bracket base 18 can be fixed to a wall or a column by bolts. By loosening the bolts between the mounting bracket 17 and the bracket base 18, the angle of the protection box 11 can be adjusted.

[0035] The waterproof component 2 includes a sealing plate 21, which is rotatably connected to the protection box 11. A waterproof shading plate 24 is slidably connected above the sealing plate 21. The waterproof component 2 is used to block rainwater. A solar panel 26 is installed on the top surface of the waterproof shading plate 24 by screws. The solar panel 26 can provide energy for the heat dissipation device 3. The waterproof component 2 is located above the air vent 14.

[0036] The sealing plate 21 is a stainless steel plate, the middle portion of the sealing plate 21 is a flat plate, and both sides of the sealing plate 21 are bent downward.

[0037] The bottom surface of the sealing plate 21 is provided with a sealing groove 22, into which the top of the protection box 11 can be inserted, and the lower edge of the sealing groove 22 is higher than the upper edge of the vent hole 14. The edge of the sealing plate 21 is lower than the lower edge of the vent hole 14.

[0038] A second rotating bracket 23 is welded to the bottom of the front side of the sealing plate 21, and a rotating bracket 16 is welded to the upper part of the front side of the protection box 11. The second rotating bracket 23 and the rotating bracket 16 are connected by a pin shaft, and the sealing plate 21 can rotate around the axis of the rotating bracket 16. The tail of the sealing plate 21 is fixedly connected to the protection box 11 by screws.

[0039] A sliding groove 25 is welded on the inner edge of the waterproof shading plate 24 , and the edge of the sealing plate 21 can be inserted into the sliding groove 25 . The front end of the waterproof shading plate 24 exceeds the front end of the sealing plate 21 .

[0040] The waterproof shading plate 24 can prevent rainwater from penetrating into the protective box 11 from the front and rear sides of the sealing plate 21. The front end of the waterproof shading plate 24 exceeds the front end of the sealing plate 21, which can prevent rainwater from hitting the light-transmitting plate 15 from the front. At the same time, it can block the sunlight entering from above, reducing the impact of direct sunlight on the imaging of the camera 4.

[0041] The heat dissipation device 3 includes a heat dissipation fan 32, which is slidably installed at the bottom of the protection box 11 through an installation drawer 31 and is connected to the solar panel 26 through a wire. The installation drawer 31 is slidably installed above the sliding plate 13. The heat dissipation fan 32 is used to blow air into the protection box 11. An automatic sealing device is provided above the heat dissipation fan 32, and the automatic sealing device is used to separate the heat dissipation fan 32 and the protection box 11.

[0042] The top surface of the installation drawer 31 is provided with a plurality of protrusions, and the heat dissipation fan 32 can just be stuck in the protrusions. After the installation drawer 31 slides into the protection box 11 from the sliding plate 13, it is fixed with the protection box 11 using screws.

[0043] The solar panel 26 converts solar energy into electrical energy, thereby driving the cooling fan 32 to work, and the cooling fan 32 generates upward airflow. The conversion rate of the solar panel 26 is affected by the intensity of sunlight. When the external light is insufficient, the amount of electricity converted by the solar panel 26 is low and insufficient to drive the cooling fan 32 to work; when the external light is strong, the amount of electricity converted by the solar panel 26 is sufficient, and the cooling fan 32 will start to work when the working voltage of the cooling fan 32 is reached.

[0044] The automatic sealing device is located at the partition plate 12, and the automatic sealing device includes a ventilation grille 37, which is snap-fitted and installed on the top surface of the partition plate 12, and the ventilation grille 37 is evenly penetrated with a plurality of square through holes. A sliding grille 33 is slidably installed on the inner side above the partition plate 12 and below the ventilation grille 37, and a metal ear 34 is welded to the left end of the sliding grille 33. The sliding grille 33 is evenly penetrated with a plurality of square through holes, and the through hole spacing and width on the sliding grille 33 are the same as those on the ventilation grille 37.

[0045] The camera 4 is fixedly mounted on the top surface of the ventilation grille 37 by means of screws.

[0046] The sliding grille 33 can slide left and right inside the partition plate 12. When the sliding grille 33 slides to the leftmost end, the through holes of the sliding grille 33 and the ventilation grille 37 are staggered, and the sliding grille 33 and the ventilation grille 37 cooperate with each other to separate the protection box 11 from the cooling fan 32. When the sliding grille 33 slides to the rightmost end, the through holes of the sliding grille 33 and the ventilation grille 37 are aligned, and the airflow generated by the cooling fan 32 can enter the protection box 11.

[0047] An electromagnet 35 is mounted on the right side of the metal ear 34 and inside the partition plate 12 . The electromagnet 35 is connected to the solar panel 26 via a wire. A return spring 36 is mounted between the electromagnet 35 and the metal ear 34 .

[0048] The electric energy generated by the solar panel 26 can drive the electromagnet 35 to work. After being energized, the electromagnet 35 generates magnetism, which can attract the metal ear 34 to move to the right, thereby driving the sliding grille 33 to slide to the right and compressing the return spring 36 at the same time; when the solar panel 26 is not exposed to enough light, the electric energy generated by the solar panel 26 is insufficient, the electromagnet 35 loses its magnetism, and the return spring 36 returns to its original state, thereby driving the metal ear 34 to move to the left, and then driving the sliding grille 33 to slide to the left.

[0049] In actual operation, the solar panel 26 can convert solar energy into electrical energy. On sunny days, when the external light is strong and the ambient temperature is high, the solar panel 26 converts more electrical energy at a higher voltage, which reaches the working conditions of the cooling fan 32 and the electromagnet 35.

[0050] When the electromagnet 35 is energized, it generates magnetism and can absorb the metal ear 34 and compress the reset spring 36. When the input voltage of the electromagnet 35 is greater than the rated voltage, the magnetic force generated by the electromagnet 35 is greater than the reset spring 36. At this time, the electromagnet 35 can completely absorb the metal ear 34 and completely compress the reset spring 36. The sliding grille 33 moves to the right under the action of the magnetic force of the electromagnet 35, and the through holes of the sliding grille 33 and the air-permeable grille 37 are aligned.

[0051] At the same time, when the input voltage of the cooling fan 32 reaches the rated voltage, the cooling fan 32 starts to work and blows air into the protection box 11. The airflow enters the protection box 11 from the through holes of the sliding grille 33 and the ventilation grille 37, and then is discharged from the ventilation hole 14 to dissipate heat for the camera 4.

[0052] When it is rainy outside, the sunlight is low and the ambient temperature is low. At this time, the electric energy converted by the solar panel 26 is low and the voltage cannot reach the rated voltage of the cooling fan 32 and the electromagnet 35.

[0053] At this time, the magnetic force generated by the electromagnet 35 after being energized is smaller than the elastic force of the return spring 36. Under the elastic force of the return spring 36, the sliding grille 33 moves to the left, and the through holes of the sliding grille 33 and the ventilation grille 37 are arranged alternately. The sliding grille 33 and the ventilation grille 37 cooperate with each other to separate the protection box 11 from the cooling fan 32, thereby preventing rainwater from invading the protection box 11 from below.

[0054] At the same time, the input voltage of the cooling fan 32 does not reach the rated voltage and will not work.

[0055] Therefore, according to the external lighting conditions, the heat dissipation device 3 can realize automatic start and stop.

[0056] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
