Description
Technical field
The present invention relates to the technical field of vidicon camera; Be that a kind of link position at vidicon camera and The Cloud Terrace adopts seal ring and grease seal simultaneously in many places specifically; Thereby improve the integral waterproofing ability, make the waterproof sealing structure of the monopod video camera that equipment can use under rugged environment.
Background technique
The Cloud Terrace is exactly the mountion plate of the vidicon camera be made up of two AC motor, can drive the motion that vidicon camera is done substantially horizontal and Vertical direction.There are two motors The Cloud Terrace inside, be responsible for respectively The Cloud Terrace up and down and the rotation of left and right sides all directions.The difference of its operating voltage has also determined the overall operation voltage of this The Cloud Terrace, and 24V, alternating current 220V and the direct current 24V of interchange generally arranged.When receiving upper and lower operation voltage, motor vertical rotates, and drives vertical transmission wheel disc through speed reducer and rotates; When receiving left and right operation voltage, horizontal motor rotates and the horizontal teeth wheel disc through speed reducer drive The Cloud Terrace bottom rotates.
The Cloud Terrace all has level, vertical limited bolt, and The Cloud Terrace is realized limit functions by two sensitive switches respectively.When rotation angle reaches predefined limited bolt, the sensitive switch action power dump, The Cloud Terrace stops operating.Limit stoper can be positioned at the The Cloud Terrace outside, and adjustment process is simple, also can be positioned at The Cloud Terrace inside, adjusts the adjustment process relative complex through the regulating mechanism of peripheral hardware.But the The Cloud Terrace sealing of external limit stoper is not as the The Cloud Terrace of built-in limit stoper.
Mutually combine through The Cloud Terrace and vidicon camera and to be monopod video camera; Through the change of The Cloud Terrace to the angle of vidicon camera, the video acquisition that can make vidicon camera accomplish a plurality of angles is taken, and common monopod video camera comprises: vidicon camera; Gather video signal, constitute the operative body part of monopod video camera; The Cloud Terrace interconnects with vidicon camera, constitutes the mountion plate of vidicon camera, drives vidicon camera in the horizontal direction and movement in vertical direction, changes the angle of shooting of vidicon camera; Base for supporting interconnects with The Cloud Terrace, and The Cloud Terrace is fixed on the precalculated position; Motor is installed in The Cloud Terrace; Interconnect through transmission shaft between The Cloud Terrace and the vidicon camera, an end and the vidicon camera of transmission shaft are fixed, and the other end is driven by above-mentioned motor; Bearing is fixed in the The Cloud Terrace through bearing support, and transmission shaft passes bearing and cooperatively interacts fixing with bearing inner race.Two motors of general installation in The Cloud Terrace inside, the control vidicon camera rotates shooting respectively in the horizontal direction with on the Vertical direction.
But, there is following not enough point in the aforesaid prior art:
The monopod video camera of existing technology all is installed in the environment of outdoor this relative complex usually; The link position of The Cloud Terrace and vidicon camera does not carry out special water-proofing treating; In use easily owing to rain heavily or the situation that vidicon camera and The Cloud Terrace inside intake respectively appears in other reasons; Thereby cause the monopod video camera can't proper functioning, its inner components and parts also damage because of water inlet easily.
Summary of the invention
