Description
Technical field
Telescope apparatus field is the utility model is related to, sun straight-tube telescope is observed more particularly to one kind.
Background technology
Telescope is a kind of optical instrument that remote object is observed using concavees lens and convex lens.Utilize the light by lens
Line reflects or light is reflected by the concave mirror and feeds them into aperture and be converged to picture, then is seen by a magnification eyepiece.Also known as
" a thousand li mirror ".First effect of telescope is to amplify the subtended angle of distant objects, human eye is seen the smaller details of angular distance clearly；Hope
Remote second effect of mirror is the coarser light beam of the ratio pupil diameter that object lens are collected into, and is sent into human eye, observer is seen
Originally the dark weak object that can't see.Telescope mainly includes lens barrel and is arranged on the eyepiece and object lens at lens barrel both ends.
During being observed using telescope the sun, user is caused to regard often due to sunshine is excessively dazzling
Power is damaged.Therefore, the eyeglass of one optical filtering of setting in telescope, the mirror are generally required when observing the sun in the prior art
Piece functions similarly to the effect of sunglasses.But in case of variable weather conditions, the brightness of the sun is different, preferably seen to obtain
Examine effect to generally require with changing different filter glass, this not only wastes time and energy, and increases use cost.
The content of the invention
The purpose of this utility model is that providing a kind of observation sun straight tube that can rapidly adapt to different illumination conditions looks in the distance
Mirror.
For achieving the above object, technical scheme is used by the utility model：One kind observation sun straight tube is looked in the distance
Mirror, including the telescope main body being made up of eyepiece, object lens and lens barrel, the lens barrel top set the lighting tube coaxial with lens barrel,
Light intensity sensor is set in the lighting tube, and the light intensity sensor is electrically connected with controller；Also include filtering assembly,
The filtering assembly includes the cylinder being co-axially located in lens barrel, and the cylinder is engaged with lens barrel；The both ends inside points of cylinder
The transmission lens that She Zhi be engaged with cylinder；Cylinder interior between the transmission lens forms gas filled cavity, the gas
Filling dinitrogen tetroxide gas in body filled cavity；Electric heating element, the electrical heating portion are additionally provided with the inwall of the cylinder
Part is located in gas filled cavity, and electric heating element is controlled by controller；The electric heating element, controller and light intensity sensor
By storage battery power supply.
Preferably, the electric heating element is heating wire or electrothermal tube.
Preferably, the outer surface of the lens barrel is additionally provided with solar panel, and the battery is by solar panel
Charging, the solar panel are located at lens barrel close to one end of object lens.
The beneficial effects of the utility model embody a concentrated reflection of, and can be changed according to different luminous intensities in gas filled cavity
The color depth of gas, it is very easy to use so as to adapt to the observation under different luminous intensities to the sun.Specifically, this reality
With it is new in use, make full use of the reversible reaction between nitrogen dioxide and dinitrogen tetroxide.Light intensity sensor connects
Receive collection light intensity signal and feed back to controller, controller controls electric heating element according to light intensity signal.When luminous intensity compared with
Gao Shi, electric heating element work, temperature rise drives dinitrogen tetroxide to be converted to nitrogen dioxide, because nitrogen dioxide is rufous
Gas, along with increasing for its concentration, the color in gas filled cavity is constantly deepened, and filter action is strong.When luminous intensity is relatively low
When, electric heating element does not work, and temperature, which reduces, drives nitrogen dioxide to be converted to dinitrogen tetroxide, because dinitrogen tetroxide is colourless
Gas, with increasing for its concentration, the color in gas filled cavity constantly shoals, and filter action is weak.Therefore, the utility model
There can be good adaptability to the sun viewing under different light intensity conditions, and it is simple in construction, it is easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of filtering assembly.
Embodiment
A kind of observation sun straight-tube telescope with reference to shown in Fig. 1 and 2, including be made up of eyepiece 1, object lens 2 and lens barrel 3
Telescope main body, the top of lens barrel 3 set the lighting tube 4 coaxial with lens barrel 3, direction and the telescope thing of the lighting tube 4
The direction of mirror is consistent.Light intensity sensor 5 is set in the lighting tube 4, and the light intensity sensor 5 is used to detect in observation
Luminous intensity, the light intensity sensor 5 is electrically connected with controller 6, and detection signal can be fed back to controller 6, the control
Device 6 processed is typically a single-chip microcomputer or other play the control chip of phase same-action.The utility model also includes filtering assembly, filter
Optical assembly is used to filter too strong sunshine.The filtering assembly includes the cylinder 7 being co-axially located in lens barrel 3, institute
Cylinder 7 is stated to be engaged with lens barrel 3, that is, the outside dimension of cylinder 7 is just suitable with the internal diameter size of lens barrel 3, consequently facilitating
The installation of cylinder 7.As shown in Fig. 2 the transmission lens 8 being engaged with cylinder 7, transmissive mirror are set respectively inside the both ends of cylinder 7
Region between piece 8 forms confined space, for filling dinitrogen tetroxide gas.Circle between namely described transmission lens 8
7 Inner Constitution gas filled cavities 9 of cylinder, the interior filling dinitrogen tetroxide gas of the gas filled cavity 9.On the inwall of the cylinder 7
It is additionally provided with electric heating element 10, conventional electric heating element 10 such as heating wire, electrothermal tube.The electric heating element 10 is located at
In gas filled cavity 9, electric heating element 10 is controlled by controller 6.The electric heating element 10, controller 6 and luminous intensity sensing
Device 5 is powered by battery 11.
The utility model in use, makes full use of the reversible reaction between nitrogen dioxide and dinitrogen tetroxide.Light
Intensity sensor 5 receives collection light intensity signal and feeds back to controller 6, and controller 6 controls electrical heating according to light intensity signal
Part 10.When luminous intensity is higher, electric heating element 10 works, and temperature rise drives dinitrogen tetroxide to be converted to nitrogen dioxide,
Because nitrogen dioxide is rufous gas, along with increasing for its concentration, the color in gas filled cavity 9 is constantly deepened, filter
Light action is strong.When luminous intensity is relatively low, electric heating element 10 does not work, and temperature, which reduces, drives nitrogen dioxide to turn to dinitrogen tetroxide
Change, because dinitrogen tetroxide is colourless gas, with increasing for its concentration, the color in gas filled cavity 9 constantly shoals, and filters
Act on weak.Therefore, the utility model can have good adaptability, and structure to the sun viewing under different light intensity conditions
Simply, it is easy to use.In order to further improve the performance that the utility model continuously works, more preferable way is, the lens barrel 3
