Abstract
The utility model belongs to an accessory of a camera in a monitoring system, particularly to a special optically transparent cover for a spherical monitoring camera. The utility model provides a hyper-hemispherical transparent cover for a monitoring camera, which comprises an optical ball cover, a flange seat, a clamping ring and a seal ring, and is characterized in that the seal ring adopts a U-shaped seal ring; the clamping ring comprises two parts; the optical ball cover comprises two ball cover components with the horizontal central angles of 0 to 180 degrees and the vertical central angles larger than 90 degrees; the edge of the optical ball cover is arranged in a groove of the seal ring; and the clamping ring wraps the seal ring and is fixed on the flange seat. The utility model has the advantages that when two ball covers are spliced, the whole body exceeds a hemisphere, so that the camera mounted inside has larger visual range, and the image quality is better than that of the conical surface of a common ball cover; the hyper-hemispherical cover can be mounted conveniently through the split type clamping ring; the U-shaped seal ring has an effective seal function; and when the clamping ring is locked and mounted, the hyper-hemispherical cover can be protected, thereby dispersing the stress generated when the clamping ring is mounted.
Description
Technical field:
The utility model belongs to the accessory of the video camera in the supervisory control system, especially belongs 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 hemisphere, 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 angle of visual field of video camera 5 is positioned at spheric region, its imaging is clear, in case and the angle of visual field 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 purpose of this utility model is to overcome the shortcoming that existing video camera translucent cover exists, and a kind of camera supervised scope that enlarges is provided, and does not influence the super hemisphere translucent cover of rig camera of its imaging definition.
The technical scheme that the utility model adopted is the super hemisphere translucent cover of a kind of rig camera, it comprises optical ball cover, flange seat, trim ring, sealing ring, its structural feature is that sealing ring 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 sealing ring, and trim ring environmental sealing circle also is fixed on the flange seat.
The utility model 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.
Advantage of the present utility model is: 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 utility model, and following embodiment is made amendment, and it all is possible adding and replacing, and does not all exceed protection range of the present utility model.
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, sealing ring 4, sealing ring 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 sealing ring 4 (as shown in Figure 4), sealing ring 4 is an interference fits 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 profile, 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 optics housing that surpasses 1/4th spheries, and horizontal central angle is 0 °-180 °, vertically central angle is-30 °-90 °.
