Description
Technical field
The utility model relates to digitized video device for shooting switching device of optical fiber.The digitized video device for shooting of using this switching device of optical fiber is equipped with optics pick-up lens, optics low pass filter (Optical Low Pass Filter usually with switching device of optical fiber, hereinafter to be referred as OLPF) and the electric charge lotus root close element (ChargeCoupled Device, C D).This switching device of optical fiber is used for controlling the optical filter with different filtering functions and inserts or withdraw from the photograph light path of digitized video device for shooting with switching device of optical fiber.
Background technology
Most of digitized video device for shooting switching device of optical fiber all needs to satisfy the requirement of round-the-clock twenty four hours running.But since daytime with night light luminance obviously different, for providing phtographic lens required light amount, usually in the daytime or understand two groups of different optical filters of functions of use night.By day, light is stronger, the light amount that makes phtographic lens pick up easily is too high, cause the image of shooting bright excessively, unclear, the optical filter that uses this moment should be the energy that can remove the light that naked eyes can't see, and for example ultraviolet ray, infrared ray etc. make more suitable light and the image of phtographic lens acquisition.But at night, light ray energy is just not enough originally, and the optical filter that uses this moment then should not have the function of isolating invisible light, must increase the penetrability of light on the contrary, or has the effect of eliminating ghost.Therefore; the digitized video device for shooting of round-the-clock twenty four hours running; especially monitor etc.; its employed switching device of optical fiber; usually can set the unit that to change the working position; station a-b box for example is so that by day or the suitable optical filter of (the perhaps environment of light darkness) its function that can automatically switch at night.
At present, commercially available digitized video device for shooting has been standardized or standardization with switching device of optical fiber, and its switching device of optical fiber only can provide a narrow space, designs one group of switching device of optical fiber voluntarily for manufacturer and is installed in this space.Known switching device of optical fiber, its structure are divided into two kinds usually.
The first utilizes electro-motor to be responsible for driving, finishes transmission with members such as gears.The shortcoming of this Mechanical Driven conversion regime is that volume is too huge, and because of limited space, the less electro-motor of output power only can be installed, so the speed of optical filter when moving is slower, the image that optical lens is picked up produces fuzzy or shadow in the optical filter moving process.
It two is to twine optical filter box with coil, and the magnetic force that cooperates magnet to produce reaches the purpose of switching optical filter.The shortcoming of this Electromagnetic Drive conversion regime is comparatively power consumption, also break down easily at low temperatures, no matter and this kind mode optical filter whether be in switch or the standby process in, all want the sustainable supply electric energy, cause power consumption higher.And when low temperature or humidity were higher, the resistance between member increased, and the acting force that coil and magnet can produce will be difficult to optical filter is moved.Moreover after repeatedly moving back and forth, the plain conductor that constitutes coil is broken easily, causes switch failure.
The utility model content
At the shortcoming that aforementioned prior art exists, the purpose of this utility model provides a kind of small and exquisite flexibly, stable level and smooth, reliable digitized video device for shooting switching device of optical fiber in location of running.
Digitized video device for shooting switching device of optical fiber according to the above-mentioned purpose design comprises sliding unit and driver element.Sliding unit is made of framework and the fitting piece that is fixed on this framework outer wall.Driver element comprises a connecting rod.Vertical first end of this connecting rod connects with the fitting piece of framework, and its second end is fixed with permanent magnet.Permanent magnet inserts to have in the ferromagnetic outer tube, and keeps the state that vertically can slide along connecting rod.
Aforementioned digitized video device for shooting switching device of optical fiber, its ferromagnetic outer tube generally adopts the nickel pipe.
Aforementioned digitized video device for shooting switching device of optical fiber can be at the conductive coil that twines on the outer wall of its nickel pipe more than at least one circle.This conductive coil to be parallel to connecting rod vertical.
Preferably, aforementioned digitized video device for shooting switching device of optical fiber, vertical first end of its connecting rod is spherical termination.Be provided with docking groove at the framework fitting piece corresponding to the position of spherical termination.Vertical first end of connecting rod is that spherical termination is buckled in the docking groove with the type of attachment between the framework fitting piece.Spherical termination is in the state that can slide in docking groove.
Preferably, aforementioned digitized video device for shooting switching device of optical fiber, the bearing of trend of its docking groove is vertical perpendicular to connecting rod.Docking groove is a bit larger tham spherical termination corresponding to the lateral dimension of the groove body of spherical termination, and the width of rebate of docking groove is a bit larger tham the part of connecting rod outside spherical termination.
More preferably, aforementioned digitized video device for shooting switching device of optical fiber is fixed with at least one optical filter in its framework.
Low according to qualifications, aforementioned digitized video device for shooting switching device of optical fiber, be fixed with in its framework along connecting rod vertically successively in abutting connection with and two optical filters there are differences of its light-filtering characteristic.
Digitized video device for shooting switching device of optical fiber of the present utility model, at a connecting rod end fixed permanent magnet longitudinally, again permanent magnet is inserted and have ferromagnetic outer tube, for example in the nickel pipe, keep vertical end of connecting rod and permanent magnet in the nickel pipe, to be in the state that vertically can slide simultaneously along connecting rod.Under this configuration state, permanent magnet just can keep the location of connecting rod well on the action of a magnetic field direction with the initial magnetic field power that exists between the nickel pipe.And on this basis,, produce its action intensity and the adjustable complementary field of direction by adding electric power via conductive coil again by on nickel pipe outer wall, twining the technical measures of conductive coil.Under the double action of initial magnetic field power and complementary field power, the location of connecting rod and position adjustments all can be well controlled.Under the transfer function of connecting rod, the sliding unit that just can drive switching device shifter inside drives optical filter and carries out change action, make the optical filter adjoin each other have when entering imaging optical path and adopt as heir characteristic and stability smoothly, perhaps under the state of outage, make the sliding unit that carries optical filter obtain to stablize constant location by initial magnetic field power in switching position mutually.This switching device of optical fiber operating process has power saving, handoff procedure is accurate fast, failure rate is low, assembling is easy, the characteristics of applied range
