Abstract
The invention relates to a steel wire rope dragged guide rail type flipping dome for protecting an antiaircraft observation instrument. A hemispheric dome is arranged above the antiaircraft observation instrument, and the invention is characterized in that the outside of an observing room is provided with a dome guide rail; the bottom of the dome is provided with a walking roller which is arranged on the dome guide rail and can move along the dome guide rail; at the same time, the middle of the outside of the observing room is also provided with a lockage lever which is arranged at one side of the observing room through a rotating shaft B; one end of the lockage lever is connected to the dome through a rotating shaft A; the other end of the lockage lever is fixed with a balancing weight; and a closed loop dragrope of a winding engine is connected to the dome. The invention adopts a brand new dome mode to open and close the dome, has no shading on the efficient sky area of the telescope, does not need to rotate along the telescope, and can not generate electromagnetic interference.
Description
Technical field
The present invention relates to a kind of dome, be specifically related to a kind of rope traction guide rail type flipping dome that is used for observation instrument (for example astronomical telescope) protection in empty day empty day observation instrument.
Background technology
Present dome usually adopt one can the orientation rotation hemisphere or the sphere structure of super hemisphere, the slit that a width does not wait is opened in the centre, is furnished with removable top cover (skylight) above, during observation, the skylight is opened, and dome rotates with telescope, to observe not the target in district on the same day.
Because dome deadweight big (the dome deadweight as 6 rice diameters is about 10 tons), when telescopical orientation rotating speed acquires a certain degree (be higher than 6 the degree/s), guarantee that dome and telescope are synchronous, need be furnished with powerful motor and corresponding controller, with high costs.Can produce electromagnetic interference in the dome running simultaneously, telescopical observation is had certain influence.
Summary of the invention
The purpose of this invention is to provide a kind of rope traction guide rail type flipping dome, this dome adopts a kind of brand new dome mode, after dome is opened, telescope whole day district is not had block, and do not need to rotate with telescope, can not produce electromagnetic interference.
When needs are observed the target of high speed or irregular movement (mainly being artificial object), telescope need be done high-speed motion, under traditional thinking, it is joined the dome of building and need be synchronized with the movement on the orientation along with telescope, guarantees that dome can not block telescopical observation.
The scheme of finishing the foregoing invention task is: a kind of rope traction guide rail type flipping dome that is used for empty day observation instrument (comprising that astronomical telescope and other are to empty day observation instrument) protection, in sight chamber (fixed building) top to empty day observation instrument, be provided with hemispheric dome, it is characterized in that the outside of this sight chamber is provided with the dome guide rail; Described dome bottom is provided with walking roller, and this walking roller is arranged on the described dome guide rail, can be along this dome guide rail movement; Simultaneously, the outer middle side part of described sight chamber also is provided with one and opens and closes lever, and this switching lever is installed in a side of described sight chamber by axis of rotation B; One end of this switching lever is connected in dome by axis of rotation A, and the other end of this switching lever is fixed with balance weight; The closed loop haulage cable of hoist engine is connected on the described dome.
In other words, structure of the present invention is: above the fixed building to empty day observation instrument sight chamber is the spheroid part of dome, in the time of in off position, telescope is fully topped in spheroid inside, prevent that effectively wind, rain, sand and dust etc. are to telescopical erosion (as Fig. 1).
The middle part of building is the axis of rotation B of dome fixedly, installs one on it and opens and closes lever, and its side is by the spheroid of axis of rotation A connection dome, and opposite side is a balance weight.Lower right, spheroid bottom is a walking roller, can be along the guide rail movement that is fixed on the building outside.
Because 3 on same straight line are not a stable triangle state in the plane, when wherein changing, leg-of-mutton shape changes thereupon.This patent dome had both utilized this principle: axis of rotation A, axis of rotation B, walking roller (guide rail constraint) are the point of three in the principle, wherein axis of rotation A and axis of rotation B, relation between axis of rotation B and the walking roller is changeless (being that leg-of-mutton two length of sides are constant), when walking roller during at power traction lower edge guide rail movement, the 3rd limit that it and axis of rotation B form is in the variation, triangle relation changes thereupon, opens thereby drive the upset of dome spheroid.
Closed loop wire rope by the hoist engine traction is fixed on the dome spheroid walking roller seat, and starting hoist engine just changes, and then opens dome, and counter-rotating then can be closed dome.
The present invention has adopted brand new dome mode to open and close dome, telescope whole day district is not had block, and do not need to rotate with telescope, can not produce electromagnetic interference.
