Description
Technical field
It is relevant that total reflection and optical fiber of the present invention with light pass light theory teaching demonstration device.
Background technology
The total reflection of existing light and optical fiber pass the one of the tank of light demonstration device (i.e. light propagates demonstration device along current)
There is horizontal-spray mouth side, and there are the optical entrance coaxial with water jet, the horizontal-spray mouth of tank in the opposite side of tank
During water outlet, the hand-held LASER Light Source at optical entrance is opened, the water outlet of horizontal-spray mouth forms semi-parabolic.Its shortcoming is water storage
Container and water jet one, the firing angle and hydraulic pressure of current are non-adjustable, and the direction of observation of students is not easy to adjust, half throwing of the light in decline
When being propagated in thing line water column, the visual angle for the student towards Demonstration table is frontlighting, inconvenience observation.For demonstration optical fiber biography light
Speech, " bendability " of semi-parabolic water column are much worse than full parabola water column intuitively, significantly.Hand-held LASER Light Source is dangerous, operation
It is inconvenient.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, easy to operate and safe, the firing angle and hydraulic pressure of current are adjustable, water
The form of diverse of stream and it is relatively stable, " bendability " of current, " linearity " be directly perceived, significantly, is constrained on the light propagated in water column
" light path " be easy to observation the full parabola light propagation demonstration device of adjustable water flow.
What the present invention was realized in：
The full parabola light propagation demonstration device of adjustable water flow of the present invention, including water source, be fixed with thereon light source 10 water jet 2, with

Mating plate 9, light source 10 are located at coaxial with the sparge pipe 8 on the lower wall of casing 6 in light transmission piece 9, and light source 10 is located at the bearing of casing upper wall
In, the side wall 12 of bearing is vertical with the upper wall of casing, has handle 13 to be connected with support in side wall 12, and water source is with water jet 2 by soft
Pipe connects, and water inlet pipe or water source outlet pipe have valve.
There is the optical screen 3 for posting level crossing 4,
The light source 10 is flashlight, and the wall 12 of the bearing is the semi-cylindrical coaxial with sparge pipe, the diameter of light transmission piece 9 with
The internal diameter or flashlight shaven head diameter of semi-cylindrical are equal, and the upper end of wall 12 is that semicircle, lower end is full circle, the upper end of wall 12
It is full circle for semicircle, lower end, the handle 13 on wall 12 is located at semi arch center and vertical with the major axis of the casing 6 of water jet.
The support being connected with water jet 2 is Square seat bracket, and the vertical hole of the head 11 of Square seat bracket on column 5 with moving down
Dynamic to coordinate, lateral aperture and the cross bar 14 of head are rotatably assorted, and head 11 has trip bolt, and the chuck of cross bar connects with the handle 13 of wall 12
Connect.
The lower end of optical screen 3 has tank 15, tank 15 to have aqueduct 16.
The water source is storage tank 1, the delivery port of storage tank 1 higher than the upper wall of the casing 6 of water jet 2 water inlet pipe 7, two
Person's flexible pipe connects.
Sparge pipe 8 has external screw thread to coordinate with nozzle.
There is lantern slide between light source 10 and light transmission piece 9.
The experiment that the present invention is propagated using light along current verifies the total reflection of light in teaching and illustrates the principle of optical fiber.
Three parts composition of the present invention：1st, by water butt, supplied water using its hydraulic pressure for water jet；2nd, light source is fixed with thereon
The water jet of (torch).Its water inlet is connected by flexible pipe with water butt lower valve.Current form thang-kng by spout
Water column.Water jet simultaneously can adjust water butt by the head of Square seat bracket in horizontal plane and vertical rotation in surface, rotation water jet
Lower valve can show the column current of different firing angles and differently curved degree.3rd, the white optical screen of level crossing is posted.By plane
Mirror Dou incisions and suitably rotate thang-kng water column, level crossing generation mirror-reflection, can allow student towards Demonstration table in level crossing
It was observed that the path of light；It is white optical screen by the frame of plastic plane definition of optical screen 3, white optical screen Dou is cut into thang-kng water column, can
The observation of students of different azimuth is allowed to hot spot（Light in water column is mapped on white optical screen and produces diffusing reflection）.
Compared with conventional same experiments device, advantages of the present invention is as follows：
First, water jet is separated with tank, water jet can be connected with flexible pipe with water butt or running water pipe, easy to operate.
2nd, safe light source is fixed on water jet, it is easy to operate, light source is done without laser, it is safer.
3rd, the firing angle of current of the present invention and hydraulic pressure are adjustable, the form of diverse of current and it is relatively stable, " bendability " of current,
" linearity " is directly perceived, notable, and " light path " for being constrained on the light propagated in water column is easy to the full parabolic linear light of adjustable water flow of observation
Propagate demonstration device.The firing angle of adjustable current and hydraulic pressure with formed straight line, it is flat throw, the guide-lighting current of different shapes such as Dou is thrown.It is special
It is not that big-elevation Dou throws the degree of crook of guide-lighting current than other same experiments significantly much, even bore hole also observes that
Light is constrained in current.
4th, the major part of optical screen is made with level crossing, when level crossing Dou cuts thang-kng current, the mirror-reflection of level crossing causes
Towards Demonstration table student from level crossing from guide-lighting current decline one section of light path from summit when be easier, light total reflection is existing
As also becoming apparent from.
5th, sparge pipe 8 has external screw thread to coordinate with variously-shaped nozzle, changes water spray shape.
6th, it is inserted with lantern slide between light source 10 and light transmission piece 9.
