Abstract
The utility model relates to a novel astronomical telescope comprising a lens cone adjusting structure, a supporting frame, a lens cone, an eye lens, a focusing cone and a finderscope. The novel astronomical telescope also comprises a lens hood, a motor controlling the lens hood to close and open, a brightness sensor, a touch sensor and a programmable controller. The novel astronomical telescope is characterized in that the lens hood is arranged on the front end of the lens cone. The edge of the lens hood is fixedly connected with a rotating shaft of the motor. The motor and the programmable controller are fixed on the external wall of the lens cone via adhesive glue or adhesive tapes. The touch sensor is arranged on the top end of the external wall of the lens cone. A touch sensing part of the touch sensor extends forwardly to the front of the lens cone and suspends above the lens hood. The contacting part of the touch sensor and the external wall of the lens cone is fixed on the external wall of the lens cone via adhesive glue or the adhesive tapes. The brightness sensor is fixed on the upper part of the touch senor via the adhesive tapes.
Description
Technical field
The utility model relates to a kind of new-type astronomical telescope, is specially the astronomical telescope that light shield can be controlled automatically.
Background technology
The astronomical telescope light shield of prior art, in use usually need artificial manual unlocking or close, and in the observation to the sun, finds that existing manual sun light shield comes with some shortcomings, and needs to improve.The one observation solar time, often have some and forget and cover light shield,, if at this moment be eager directly to observe the sun, is easy to injure eyes.it is two in the process to sun observation, someone is not intended to open light shield, cause burning camera, camera, the human eye of perhaps burning, it is three in the total solar eclipse stage, light can be dimmed suddenly, astronomical telescope is covered with light shield and can't observes, at this moment need to open fast light shield, but because the action of opening light shield needs certain hour, important astronomical phenomena when action will be missed slightly slowly total solar eclipse and just occurred---as only have several seconds but simply marvelous Bailys bead phenomenon, its four observation the sun process in, impact due to cloud layer etc., sun brightness meeting is greatly dimmed, but the observer dare not at will take down sun light shield for the safety of eyes, sun light shield can be covered with and the sun can't be observed again.Based on above problem, astronomical sight need a can change automatically to control with sun brightness open or the astronomical telescope of the light shield that closes.
The utility model content
The purpose of this utility model is in order to make up the deficiency of above-mentioned technology, the astronomical telescope that provides a kind of light shield automatically to control.
For achieving the above object, the technical scheme that the utility model provides is: new-type astronomical telescope, comprise lens barrel adjustment structure, support, lens barrel, eyepiece, focusing drum and finder, also comprise light shield, and control closed motor, brightness impression device, touch sensor, the Programmable Logic Controller with opening of light shield; Light shield is arranged on the front end of lens barrel, and the light shield slightly larger in diameter is in the diameter of lens barrel opening, and the edge of light shield is fixedly connected with the rotation axis of motor.Motor, Programmable Logic Controller are fixed on the outer wall of lens barrel by glue or adhesive tape, touch sensor is arranged on the top of lens barrel outer wall, the touching induction part of touch sensor reaches the front of lens barrel, be suspended from the top of rotatable light shield, detect light shield and whether forwarded the restriction position to, touch sensor and lens barrel wall contact portion are fixed on the lens barrel wall by glue or adhesive tape, and the brightness impression device is fixed on the top of touch sensor by adhesive tape.The output terminal of Programmable Logic Controller is connected with motor.The signal input part of Programmable Logic Controller is connected with brightness impression device, touch sensor, and whether Programmable Logic Controller, by with the interior information of establishing, comparing analysis, rotates the detection signal of brightness impression device and touch sensor thereby control motor.
Described brightness impression device detects the variation of sun brightness constantly, the sunlight intensity signal that the brightness impression device will detect passes to Programmable Logic Controller by input end, Programmable Logic Controller compares the numerical value that is set in advance by the user in signal and Programmable Logic Controller, making corresponding judgement, is that motor sends corresponding action command to performance element.
Brightness impression device detection signal numerical value is during less than the numerical value that sets in advance, and Programmable Logic Controller judges according to numerical value, is divided into two kinds of situations, if the first situation light shield is in open mode, Programmable Logic Controller does not send signal, and motor does not rotate, and light shield remains in open mode; If the second situation light shield is in closure state, Programmable Logic Controller sends signal, and motor starts backward rotation, and rotation time stops operating to motor, and light shield is opened fully.
Brightness impression device detection signal numerical value is during greater than the numerical value that sets in advance, Programmable Logic Controller judges according to numerical value, also be divided into two kinds of situations, if the first situation light shield is in open mode, Programmable Logic Controller sends signal, the motor forward rotation, light shield starts closure, when light shield fully closed, light shield is encountered the touching induction part of touch sensor, and touch sensor sends signal to Programmable Logic Controller, and Programmable Logic Controller sends signal, motor stops operating, and light shield reaches closure state; If the second situation light shield is in closure state, Programmable Logic Controller does not send signal, and motor does not rotate, and light shield still is in closure state.
For safety, the original state of Programmable Logic Controller is: Programmable Logic Controller sends information, and the motor forward rotation makes light shield be in closure state.
Light shield of the present utility model can prepare various sizes, is used for the astronomical telescope of any bore, any type.
After adopting technique scheme, the light shield of astronomical telescope can be realized automatically controlling according to user's setting, avoids begining to learn the student who uses the astronomical telescope observation sun, cause injury to eyes because forget to cover light shield, improved the security performance of astronomical telescope; Simultaneously the utility model also for the important stage of total solar eclipse observation as only having several seconds but simply marvelous Bailys bead phenomenon etc. provide huge observation convenient.
