DETAILED DESCRIPTION

[0032] 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. Example

[0033] A camera protection device comprises a protection box 1, a heat dissipation box 3 and a heat dissipation device; an observation port is arranged on one side of the protection box 1, an air inlet 20 is arranged on the other side, and a cover plate 6 is detachably connected to the top of a camera 7; the camera 7 is arranged in the protection box 1, and a lens of the camera 7 cooperates with the observation port;

[0034] A plurality of air guide grooves 9 are arranged on the two side walls inside the protection box 1; the heat dissipation box 3 is fixedly connected to the two sides of the protection box 1; a vent 23 is arranged between the protection box 1 and the heat dissipation box 3 near the observation port; an air outlet 5 is arranged on one side of the heat dissipation box 3, and the other side is connected to the protection box 1 through the vent 23;

[0035] The heat dissipation device includes a heat dissipation fan 22 and a heat dissipation plate 21 ; the heat dissipation fan 22 is arranged in the heat dissipation box 3 near the air outlet 5 and the air outlet direction of the heat dissipation fan 22 is toward the air outlet 5 , and the heat dissipation plates 21 are evenly spaced in the heat dissipation box 3 .

[0036] Specifically, in actual use, the camera 7 is placed in the protective box 1 and the lens of the camera 7 is aligned with the observation port to prevent the lens line of sight from being blocked. The cover plate 6 is installed on the protective box 1 by screws. The camera 7 is protected in the protective box 1, which can protect the camera 7. When the camera 7 is working, the camera 7 generates heat and heats the protective box 1. Turn on the cooling fan 22, and the cooling fan 22 draws air from the vent 23 and blows toward the air outlet 5. During the air extraction process of the cooling fan 22, the hot air in the protective box 1 flows from the air guide groove 9 to the vent 23. At the same time, the air in the air guide groove 9 fully contacts the camera 7 and takes away part of the heat of the camera 7, thereby achieving cooling and heat dissipation of the camera 7. Since the camera 7 has a large contact area with the protective box 1, the heat of the camera 7 is easily transferred to the protective box 1, and the protective box 1 then transfers the heat to the heat dissipation box 3 and the heat dissipation plate 21 in the heat dissipation box 3. The cooling fan 22 cools down the heat sink 21 when blowing air, so that the heat sink 21 can continuously absorb the heat of the protection box 1 and the heat sink 3, thereby cooling the whole.

[0037] In a preferred embodiment, a protective ring 2 is fixedly connected to the outer side of the observation port outside the protection box 1. The protective ring 2 is used to protect the lens of the camera 7 to prevent the splashing materials from scratching the lens.

[0038] In a preferred embodiment, a connecting plate 24 is provided at the bottom of the protective box 1 near the air inlet 20, a waist-shaped hole is provided on the connecting plate 24, and a clamping piece 8 is also movably connected to the connecting plate 24; the clamping piece 8 is an L-shaped structure, and the clamping piece 8 is used to clamp the camera 7. A bolt hole is provided at the bottom of the clamping piece 8, and the clamping piece 8 is connected to the connecting plate 24 by bolts. After the camera 7 is installed in the protective box 1, the clamping piece 8 is pushed and pressed against the camera 7 to fix the position of the camera 7, and then the clamping piece 8 is fixed to the connecting plate 24 by bolts. The waist-shaped hole is designed to facilitate the movement of the clamping piece 8. After the clamping piece 8 is moved, the clamping piece 8 can be fixed to the connecting plate 24 by passing the bolt through the bolt hole and the waist-shaped hole.

[0039] In a preferred embodiment, a first dustproof net 10 is provided at the air inlet 20. The first dustproof net 10 is used to filter dust impurities in the air coming in from the air inlet 20, prevent dust from being deposited too quickly in the protective box 1, and ensure the normal operation of the camera 7.

The function of the guide pipe 4 is to separate the air inlet 20 from the air outlet 5, so as to prevent the hot air discharged from the air outlet 5 from entering the protection box 1 from the air inlet 20. This design can effectively improve the heat dissipation effect.

[0041] In a preferred embodiment, the air inlet end of the guide pipe 4 is tilted, and a second dustproof net 19 is provided at the position of the air inlet end. The tilted air inlet end and the second dustproof net 19 can increase the contact area between the dustproof net and the air, thereby improving the filtering effect.

When air enters the guide pipe 4 from the air inlet end, it will contact the water in the dust reduction groove 14, and the fine dust in the air will absorb the water and fall down, thereby further reducing the dust in the inhaled air. The water leakage hole 16 is used to discharge the water in the dust reduction groove 14, and the plug 15 is used to plug the water leakage hole 16.

[0043] In a preferred embodiment, at least two dust reduction grooves 14 are provided, and a dust shield 1812 is provided at the top of the dust reduction groove 14 in the guide pipe 4; the water level in the dust reduction groove 14 does not exceed the bottom of the dust shield 1812.
