Abstract
The utility model relates to an opening and closing structure for an efflorescence type of dome which comprises a dome constituted by at least two roof petals the root of which has a hinge connection with the dome wall and between each of which and the dome wall is equipped a drive mechanism. The utility model is characterized in that: A torsional spring is equipped at a pivot located between the roof petal and the wall wherein is also equipped a suspension cable one end of which connects the roof petal and the other end of which connects an electric winch equipped at the wall by a standing pulley equipped at the wall. At one end wherein the roof petal connects the suspension cable is equipped a mobile pulley. A stroke position-limiting switch is equipped to correspond to the states of complete opening and complete closing and located at a circuit of power supply of the electric winch.
Description
Technical field
The utility model relate to astronomical telescope or other plant and instrument blossom observation dome, particularly blossom dome open and close mechanism, belong to astronomical, mechanical field.
Background technology
The astronomical telescope of observation celestial body generally is to be placed in the sight chamber with movable dome.Dome commonly used has upper and lower open-type and left and right open-type, its common drawback be dome as the slide rail type slide door or window, all can not open fully, instrument can only be by the skylight opening opened to External Observation, will cause like this that sight chamber is inside and outside a temperature difference, the Instrument observation effect is affected.The domed wall portions branch of not opening produces to absorb to electromagnetic wave and disturbs in addition, and influence is to the target following observation of fast moving.02257830.7 patent application has proposed a kind of blossom dome that can complete opening, this dome is constituted by at least two top lobes, the root of every top lobe is connected with rotunda is hinged, the open and close of dome, finish by the transmission mechanism that is provided with between every top lobe and dome wall, when above-mentioned patent application has exemplified a kind of Worm and worm-wheel gearing and has realized every top lobe or part open and close.
Summary of the invention
The purpose of this utility model provides a kind of transmission and uses the mechanism that opens and closes of more reliable blossom dome, i.e. hoist cable formula mechanism for opening/closing, and its technical scheme is as follows:
The blossom dome open and close mechanism, comprise the dome that constitutes by at least two top lobes, dome is provided with the sealing rain-proof structure, the root and the dome wall of every top lobe are hinged, be provided with transmission mechanism between every top lobe and dome wall, it is characterized in that said transmission mechanism is: on the hinge between top lobe and dome wall, torsion spring is set, and between top lobe and dome wall, hoist cable is set, one end of hoist cable directly is connected with the top lobe or movable pulley connects, the other end by the fixed pulley that is provided with on the dome wall after be arranged on dome wall on electric winch be connected.When movable pulley connects, after walking around the movable pulley that is arranged on the lobe of top, an end of hoist cable is connected on the dome wall.Complete opening and closed condition corresponding to the top lobe can be provided with lead limit switch, are connected in the electric power loop of electric winch.
Advantage of the present utility model and effect are: open and close structure with the worm and gear transmission and compare, after the top lobe was opened, the suffered power of hoist cable and transmission mechanism was less, and structure is also simpler.
Description of drawings
Fig. 1 is dome structural behavior figure of the present utility model when closing;
Structural behavior figure of the present utility model when Fig. 2 is the dome unlatching.
The specific embodiment
Referring to Fig. 1,2, the observation dome is constituted by some top lobes 1, after all top lobes are closed and closed up, forms hemispherical, and all top lobes are opened the flower of back as same opening.Every top lobe can be opened or be closed simultaneously by separately transmission mechanism control, also can partly open or close.The root of every top lobe can be connected on the igloo body of wall 8 with two hinges 7.Be wound with torsion spring 6 on the hinge, a hoist cable 5 is set, the one end can directly be fixed on the top lobe 1, also can by one with movable pulley 3 that the top lobe links to each other after be fixed in the point of 4 on the body of wall again.Adopting the benefit of movable pulley is the load that can reduce to act on hoist cable and the hoist engine, thereby reduces the cost of mechanism for opening/closing.The hoist cable other end by the fixed pulley 2 that is provided with on the dome body of wall after, be connected to the electric winch 9 that is installed on the dome wall, the height that fixed pulley 2 is installed on hinge 7 top is H, when opening the top lobe, start hoist engine 9, loosen hoist cable 5, under the effect of torsion spring 6 power, promote top lobe 1 and make opening movement.After the top lobe was opened certain angle, the deadweight of top lobe will make the top lobe continue to do opening movement, and up to complete opening, hoist engine is stopped by the limitation travel switch outage, and hoist cable 5 is held the top lobe, makes it be held open state.When closing the top lobe, start hoist engine and tighten up hoist cable, the top lobe is rotated around hinged point, be bordering on when closing fully, torsion spring will be compressed, and the power of the energy that it gathers will open as next time the time.After closing fully, limit switch stops the hoist engine outage.With a radius is that 3 meters the worker's dome of blooming is an example, and top lobe number is got 6, and H highly is taken as 1 meter.In the utility model, the rainproof and hermetically-sealed construction after the top lobe closes up is with 02257830.7 patent application.
Claims (3)
1, the blossom dome opens and closes mechanism, comprise the dome that constitutes by at least two top lobes, dome is provided with the sealing rain-proof structure, the root and the dome wall of every top lobe are hinged, be provided with transmission mechanism between every top lobe and dome wall, it is characterized in that said transmission mechanism is: on the hinge between top lobe and dome wall, torsion spring is set, and between top lobe and dome wall, hoist cable is set, one end of hoist cable directly is connected with the top lobe or movable pulley connects, the other end by the fixed pulley that is provided with on the dome wall after be arranged on dome wall on electric winch be connected.
2, blossom dome according to claim 1 open and close mechanism, when it is characterized in that movable pulley connects, be connected on the dome wall after an end of hoist cable is walked around the movable pulley that is arranged on the lobe of top.
3, blossom dome according to claim 1 and 2 open and close mechanism, it is characterized in that complete opening and closed condition corresponding to the top lobe, lead limit switch is set, be connected in the electric power loop of electric winch.
