The utility model provides a monitoring camera capable of automatically adjusting shading brightness, which adopts photosensitive color-changing material to make shading eaves, the shading eaves can be darkened rapidly under the irradiation of light and ultraviolet rays to shade sunlight, and can be recovered to be colorless transparent state rapidly after the light is darkened, thereby ensuring the transmittance of the shading eaves; the device can realize automatic shading adjustment without a mechanical structure, simplifies the structure and saves the cost.

Description

But surveillance camera head of automatically regulated shading luminance

Technical Field

The utility model relates to a video monitoring technical field, especially a but surveillance camera head of automatically regulated shading luminance.

Background

The monitoring camera arranged outdoors can be influenced by sunlight irradiation to cause the exposure to be inconstant, the normal video recording function of the camera can be influenced when ultraviolet rays are very strong, and the exposure phenomenon can occur on the picture. Although various devices for shading the camera exist in the market, such as a security monitoring camera disclosed in the chinese utility model patent with the publication number CN210781047U, the scheme is provided with a retractable plate, and the shading area is adjusted by adjusting the length of the retractable plate; the relative position of adjusting camera and light screen is adopted to carry out optic fibre and is adjusted mostly to equipment on the market at present, has increased the mechanical structure of camera body, and need increase photosensitive equipment or artifical real-time regulation, and the reliability is poor, and work flow is complicated, has increased fortune dimension cost.

Disclosure of Invention

The utility model aims to solve the technical problem that a but automatically regulated shading luminance's surveillance camera head is provided, can be according to illumination intensity, the light intensity of automatically regulated camera lens department.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a but surveillance camera head of automatically regulated shading luminance, includes the camera body, is equipped with the camera lens at the front end of camera body, at the fixed guard plate that is equipped with in the top of camera body, has the clearance between guard plate and the camera body, at the front end fixedly connected with shading eaves of guard plate, shading eaves are located the top of camera lens front side, the shading eaves is made for transparent sensitization discoloration material.

Preferably, the bottom fixedly connected with bracing piece of guard plate, the tip of bracing piece extends to the front side of guard plate, and the shading eaves fixed connection is on the bracing piece.

Preferably, the top of the protection plate is provided with heat dissipation holes.

Preferably, two sides of the shading eaves are of downward bent structures.

Preferably, both sides of the protection plate are of a downward bent structure.

Preferably, the rear end of camera body is equipped with the backplate, and the area of backplate is greater than the cross section of camera body, and guard plate fixed connection is in the upper end of backplate.

The utility model provides a monitoring camera capable of automatically adjusting shading brightness, which adopts photosensitive color-changing material to make shading eaves, the shading eaves can be darkened rapidly under the irradiation of light and ultraviolet rays to shade sunlight, and can be recovered to be colorless transparent state rapidly after the light is darkened, thereby ensuring the transmittance of the shading eaves; the device can realize automatic shading adjustment without a mechanical structure, simplifies the structure and saves the cost.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the support rod of the present invention;

fig. 3 is the structure schematic diagram at the top of the camera body of the utility model.

Detailed Description

As shown in fig. 1, a monitoring camera capable of automatically adjusting shading brightness, which comprises a camera body 1, wherein a lens 2 is arranged at the front end of the camera body 1, a protection plate 3 is fixedly arranged above the camera body 1, a gap exists between the protection plate 3 and the camera body 1, a shading eave 4 is fixedly connected to the front end of the protection plate 3, the shading eave 4 is positioned above the front side of the lens 2, and the shading eave 4 is made of a transparent photochromic material. Shading eaves 4 that transparent sensitization color-changing material made are similar to changeable colour sunglasses, can darken rapidly under light and ultraviolet irradiation, shelter from sunshine, and after light darkened, the transmittance of shading eaves is guaranteed to the colorless transparent state of recovering fast.

Preferably, as shown in fig. 2, a support rod 5 is fixedly connected to the bottom of the protection plate 3, the end of the support rod 5 extends to the front side of the protection plate 3, and the light-shielding eave 4 is fixedly connected to the support rod 5. The shading eave 4 can be adhered to the support rod 5.

Preferably, as shown in fig. 3, the top of the protection plate 3 is provided with a heat dissipation hole 7. The heat dissipation hole 7 accelerates the heat dissipation of the camera, and the protection plate 3 plays a role in shielding the heat dissipation hole 7.

Preferably, two sides of the light-shielding eave 4 are bent downwards. The maximum area of the shading eave 4 shades the lens.

Preferably, both sides of the protection plate 3 are bent downward.

Preferably, the rear end of camera body 1 is equipped with backplate 6, and the area of backplate 6 is greater than camera body 1's cross section, and guard plate 3 fixed connection is in the upper end of backplate 6. Backplate 6 and guard plate 3 protect camera body 1, and guard plate 3 that both sides are buckled downwards protects the camera body from multi-angle to prevent that the rainwater from getting into the louvre.

The utility model discloses well shading eaves 4's length can be confirmed according to the user demand of reality, and simple structure is installed to this device, and is with low costs, and is very practical in the in-service use.
