[0021] The present application will be further described below in combination with the drawings and specific embodiments.​​

[0022] A fixing and switching device of a three-frequency-band feed source, comprising a C feed source, a C feed source support seat, a Ka / Ku feed source, a Ka / Ku feed source fixing seat, a main surface, a vice surface support rod, a vice surface switching shaft, a C feed source vice surface, a Ka / Ku feed source vice surface, a turnover motor group and a code disc.

[0023] The device is connected to an antenna seat frame through the C feed source support seat.

[0024] The C feed source, the Ka / Ku feed source fixing seat and the main surface are connected to the C feed source support seat; the Ka / Ku feed source is fixed to the Ka / Ku feed source fixing seat; the vice surface support rod is fixed to the main surface; the vice surface switching shaft is connected to the vice surface support rod; the C feed source vice surface, the Ka / Ku feed source vice surface, the turnover motor group and the code disc are connected to the vice surface switching shaft.

[0025] The Ka / Ku feed source fixing seat and the C feed source support seat form an oblique angle, and the Ka / Ku feed source vice surface and the C feed source vice surface fixed to the vice surface switching shaft also form a corresponding angle, which is a corresponding relationship and can be calculated.

[0026] The turnover motor group can drive the vice surface switching shaft to rotate the C feed source vice surface and the Ka / Ku feed source vice surface, and the code disc can read the angle of rotation; when switching from the C feed source to the Ka / Ku feed source, the vice surface switching shaft directly rotates the Ka / Ku feed source vice surface to the position corresponding to the feed source, without the need for feed source switching, and only the vice surface switching achieves the switching effect.

[0027] The Ka / Ku feed source fixing seat and the C feed source support seat are designed in an integrated manner and are fixedly connected to the antenna seat frame, and only follow the movement of the antenna seat frame, and the relative position between the two is unchanged.

[0028] When the feed source is switched, the Ka / Ku feed source fixing seat and the C feed source support seat do not need to move, the vice surface switching shaft drives the vice surface to rotate through the turnover motor group, and after the vice surface is rotated according to the calculated angle, it is exactly corresponding to the feed source to be switched and can be directly put into use.

[0029] The following is a more specific embodiment:

[0030] Referring to Figures 1 to 3 , the embodiment is a fixing and switching device of a three-frequency-band feed source, comprising a C feed source 1, a C feed source support seat 2, a Ka / Ku feed source 3, a Ka / Ku feed source fixing seat 4, a main surface 5, a vice surface support rod 6, a vice surface switching shaft 7, a C feed source vice surface 8, a Ka / Ku feed source vice surface 9, a turnover motor group 10 and a code disc 11.

[0031] The entire device is connected to an antenna seat frame through the C feed source support seat 2.

[0032] The C feed source 1, the Ka / Ku feed source fixing seat 4 and the main surface 5 are connected to the C feed source support seat 2; the Ka / Ku feed source 3 is fixed to the Ka / Ku feed source fixing seat 4; the auxiliary surface support rod 6 is fixed to the main surface 5; the auxiliary surface switching shaft 7 is connected to the auxiliary surface support rod 6; the C feed source auxiliary surface 8, the Ka / Ku feed source auxiliary surface 9, the turnover motor set 10 and the code disc 11 are connected to the auxiliary surface switching shaft 7.

[0034] The turnover motor set 10 can drive the auxiliary surface switching shaft 7 to rotate the C feed source auxiliary surface 8 and the Ka / Ku feed source auxiliary surface 9, and the code disc 11 can read the angle of rotation. When switching from the C feed source 1 to the Ka / Ku feed source 3, the auxiliary surface switching shaft 7 directly rotates the Ka / Ku feed source auxiliary surface 9 to the position corresponding to the feed source, without the need for feed source switching, and only the auxiliary surface switching achieves the switching effect.

[0035] The Ka / Ku feed source fixing seat 4 and the C feed source support seat 2 are designed in an integrated manner and are fixedly connected to the antenna seat frame. The Ka / Ku feed source fixing seat 4 and the C feed source support seat 2 only move with the antenna seat frame, and the relative position between them does not change.

[0036] When the feed source is switched, the Ka / Ku feed source fixing seat 4 and the C feed source support seat 2 do not need to move. The auxiliary surface switching shaft 7 drives the auxiliary surface to rotate through the turnover motor set 10. After the auxiliary surface is rotated according to the calculated angle, it corresponds to the feed source to be switched and can be directly put into use.
