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 DEG and 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 fixed on 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 and locked, and disperses the stress generated during installing the clamping ring.
Description
Technical field:
The invention belongs to the accessory of the video camera in the supervisory system, especially belong to the special-purpose optics translucent cover of ball-type rig camera.
Background technology:
For ball-shaped camera, optical ball cover not only plays the effect of protection video camera, also should guarantee the clear picture of video camera and enough monitoring ranges.Be subjected to the restriction of manufacture craft, common ball cover is semisphere, and when it highly surpassed hemisphere, for molding easy to make, its global shape for the conical surface is connected with spherical transition, was maximum at its end diameter as shown in Figure 1.As shown in Figure 2, video camera 5 is installed near the center of ball cover 1, can the 360 ° unrestricted rotation of its horizontal direction, vertical direction can only 0 ° to 90 ° rotation, when the field angle of video camera 5 is positioned at spheric region, its imaging is clear, in case and the field angle of video camera can't obtain distinct image when being positioned at the cylinder or the conical surface, in the time of therefore near video camera rotates to 0 °, its parts of images need see through the conical surface and come imaging, picture element can not meet the demands, so the anglec of rotation of video camera vertical direction only limits to 5 ° to 90 °, in actual use, user's function of wishing to make a video recording has bigger monitoring range, but ball cover has limited giving full play to of camera function.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that existing video camera translucent cover exists, a kind of camera supervised scope that enlarges is provided, do not influence the super hemisphere translucent cover of rig camera of its imaging definition.
The technical solution adopted in the present invention is the super hemisphere translucent cover of a kind of rig camera, it comprises optical ball cover, flange seat, trim ring, O-ring seal, its structural feature is that O-ring seal is the U RunddichtringO, trim ring is made of two parts, optical ball cover is that 0 °-180 °, vertical central angle constitute for the ball cover assembly greater than 90 ° by two horizontal central angles, its edge places in the groove of O-ring seal, and trim ring environmental sealing circle also is fixed on the flange seat.
The present invention utilizes two to surpass 1/4 ball covers and splice, and makes its whole hemisphere that surpasses, and has not only satisfied the needs of manufacture craft but also has satisfied the needs of video camera imaging, and the solution ball cover influences the problem of camera supervised scope with looking for another way.
Vertical central angle is-80 °-90 °, and is inner as long as the opening that optical ball cover stays can allow the fixing or slew gear of video camera stretch into ball cover, can make the monitoring range maximization of video camera like this.We select vertical central angle to be-30 °-90 ° in the practical application.
The invention has the advantages that: 1, the whole hemisphere that surpasses in ball cover splicing back makes the inner video camera of installing that bigger visual range be arranged, and provides than common ball cover conical surface picture quality more clearly.2, split type trim ring is convenient to the installation of super hemisphere cover.3, the U RunddichtringO can effectively play sealing function, is beneficial to installation, and when the locking trim ring is installed, and super hemisphere cover is also played the effect of protection, the stress that has produced when having disperseed the installation trim ring.

Embodiment
The following examples can make the professional and technical personnel more understand the present invention, and following embodiment is made amendment, and it all is possible adding and replacing, and does not all exceed protection scope of the present invention.
As shown in Figure 3, the super hemisphere translucent cover of a kind of rig camera, it comprises optical ball cover 1, flange seat 2, trim ring 3, O-ring seal 4, O-ring seal 4 is the U RunddichtringO, trim ring 3 is made of two parts, and optical ball cover 1 is that 0 °-180 °, vertical central angle constitute for the ball cover assemblies greater than 90 degree by two horizontal central angles, and its edge places in the groove of O-ring seal 4 (as shown in Figure 4), O-ring seal 4 is a transition fit with the ball cover edge, and trim ring 3 environmental sealing circles 4 also are fixed on the flange seat 2.Fig. 5 is super hemisphere ball cover sectional view, vertical central angle can be-80 °-90 °, inner in the practical application as long as the opening that optical ball cover stays can allow the fixing or slew gear of video camera stretch into ball cover, be-30 °-90 ° among the figure, make that the anglec of rotation of video camera vertical direction can be from-25 ° to 90 °, enlarged the monitoring range of video camera, single half of ball cover such as Fig. 6, shown in Figure 7, it is an optical housing that surpasses 1/4th spheries, and horizontal central angle is 0 °-180 °, vertically central angle is-30 °-90 °.
