Hyper-hemispherical optical transparent cover of spherical monitor camera convenient for draft

Abstract

The present invention belongs to an accessory of a camera in a monitoring system, particularly belongs to an optics transparent cover specially used for a spherical monitor camera. The invention relates to a monitor camera hyper-hemispherical transparent cover, comprising an optics spherical cover, a flange seat, a clamping ring and a sealing ring, and the essential of the structure is that the sealing ring is a U-shape sealing ring, the clamping ring is composed of two parts, the optics spherical cover is composed of two spherical cover assemblies with a horizontal central angle of 0-180 DEGand a vertical central angle of greater than 90 degrees, the edge of the optics spherical cover is arranged in the groove of the sealing ring, and the clamping ring wrapping the sealing ring is fixedon the flange seat. The monitor camera excess hemisphere transparent cover has the advantages that the spherical cover exceeds a hemisphere on the whole after splicing, allows the camera equipped therein to have a larger visual scope, and provides more legible image quality than that provided by a common spherical cover conical surface; the split type clamping ring is convenient for the installation of the excess hemisphere cover; the U-shape sealing ring effectively plays a role of sealing, also plays a role of protection to the excess hemisphere cover when clamping ring is being mounted andlocked, and disperses the stress generated during installing the clamping ring.

Description

Technical field: [0001] The invention belongs to accessories of cameras in a monitoring system, in particular to a special optical transparent cover for spherical monitoring cameras. Background technique: [0002] For the dome camera, the optical dome cover not only protects the camera, but also ensures the clear image of the camera and sufficient monitoring range. Restricted by the manufacturing process, the usual dome cover is hemispherical. When the height exceeds the hemisphere, the overall shape is as follows for the convenience of mold making. figure 1 As shown, it is a transition connection between a conical surface and a spherical surface, and the diameter is the largest at its end. Such as figure 2 As shown, the camera 5 is installed near the center of the dome cover 1, and its horizontal direction can rotate 360° unlimitedly, and the vertical direction can only rotate from 0° to 90°. When the field of view of the camera 5 is located in a spherical area, its imag...

Problems solved by technology

[0005] The present invention uses two more than 1 / 4 of the dome cover to splice, so that the whole exceeds the hemisphere, which not only meets the needs of the manufacturing process but also meets the needs of camera imaging, and solves the problem that the dome cover affects the monitoring range of the camera in another way
