Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
As shown in Figure 1, be satellite antenna Rotable Control System embodiment sectional view of the present invention, the parabolic part of satellite antenna and supporting plate 1 are fixed by screw, and fixed axis 4 is fixed by screw with the base of satellite antenna, and this rotating control assembly comprises supporting plate 1; Being fixed on can be around the screw 7 flexible driving lever 2 that rotate on the supporting plate 1; Inductive switch 3, described inductive switch 3 be fixed on the supporting plate 1 and the scope that when driving lever 2 rotates, can touch in; Fixed axis 4 is arranged in the supporting plate 1, and fixed axis 4 can rotate mutually with supporting plate 1, that is to say that supporting plate 1 can rotate around the central shaft of fixed axis 4; Described fixed axis 4 is provided with rotating part 6, and it can rotate freely around fixed axis 4, and rotating part 6 can be stirred driving lever 2 when rotated and freely rotate around screw 7; The top of fixed axis 4 is provided with prevention cover 5, and described prevention cover 5 is fixed on the fixed axis 4 by screw, and one side is provided with boss, and boss can be stirred rotating part 6 around fixed axis 4 rotations during rotation.
Described fixed axis and base are fixing as a whole, satellite antenna is parabolic to be fixed as another integral body with supporting plate, these two integral body can be mutually around the central shaft rotation of fixed axis, so the satellite antenna parabola is can not be the relation of rotating mutually between them along with base rotates.
As shown in Figure 2, it is satellite antenna Rotable Control System embodiment vertical view of the present invention, when in the satellite antenna motion process, when parabolic antenna relatively rotates certain angle along with supporting plate 1 around fixed axis 4, described certain angle refers to: no matter how initial position concerns, boss on prevention cover 5 is stirred rotating part 6 rotations, and rotating part 6 rotations are up to stirring driving lever 2 around screw 7 swings, the angle of rotating between parabolic antenna and the fixed axis in this process (in this process parabolic antenna around the fixed axis center rotatablely move through angular dimension), prevention cover 5 drives rotating part 6 motions, rotating part 6 is stirred driving lever 2 touch inducing switches 3, give the control system feedback information by the lead on the inductive switch, control system sends the angular range of instruction control satellite antenna rotation, control system transmits control signal for motor (motor is fixed on the supporting plate 1 by screw), current signal for example, the rotational angle range of control motor is controlled the angular range of the rotation of parabolic antenna; Positive and reverse return by the control motor transfers the positive and negative rotation of controlling parabolic antenna, is specifically judged by control system and determines (reality is exactly to be determined by software algorithm), and described rotation comprises positive and negative dual mode.
Fixed axis 4 and rotating part 6 are formed a rotary device, included but not limited between fixed axis and the rotating part that spring connects, be designed to the fixedly assembling device of rotation angle range, when rotating to the angle of setting, fixed axis and rotating part stop operating the control system control satellite antenna reverse rotation that sends instructions again.The advantage of this scheme be simple in structure, cost is low, shortcoming is that stopping of rotating will lean on the mechanical collision of assembling device to realize, can damage other related device, reduces the life-span.
As a preferred embodiment, inductive switch quantity does not wherein limit, can 1
-N (n〉1), a plurality of switches are used for the feedback information of the corresponding a plurality of positions of control and then the rotation angle range of more accurate control satellite antenna.
In above-described embodiment, described inductive switch 3 can be the mechanical sense inductive switch, also can be magnetic induction switch, also can be the optocoupler inductive switch.When described induction opens the light 3 when the mechanical switch: touch the contact on the mechanical switch when driving lever rotates; When described induction opens the light 3 when the magnetic induction switch: driving lever is provided with magnet, and the induction point on magnet and the magnetic induction switch is the touch inducing switch apart from the scope that inductive switch can be sensed the time; When described induction opens the light 3 when the optocoupler inductive switch: driving lever is provided with reflection platform or boss, and when driving lever rotated to certain position, the optocoupler inductive switch was touched under the effect of reflection platform or boss.
This satellite antenna Rotable Control System can be applied in the control of Shipborne satellite antenna rotation angle range, rotation angle range control precision, the device that when having solved Shipborne satellite antenna work satelloid has been produced damages easily, the anti-unreasonable winding problem of lead, improved life-span and the reliability of Shipborne satellite antenna.
When the satellite earth antenna initialization rotates to certain angle, rotating part drives driving lever touch inducing switch, feed back to control system information, sent instructions to control the angular range of satellite earth antenna rotation by control system, avoid the uncontrollable device failure of bringing of rotational angle range, low problem of life-span, can also twine the number of turns by pilot in addition, avoid lead to cause losing efficacy because twining the problem that produces.
Above-mentioned explanation illustrates and has described a preferred embodiment of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to the disclosed form of this paper, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can in invention contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not break away from the spirit and scope of the present invention, then all should be in the protection range of claims of the present invention.
