[0002] If the mechanism that controls the rotation of the satellite antenna (such as a gyroscope) is damaged or worn, it may cause inaccurate adjustment angles.

This situation may be caused by a variety of reasons, such as circuit failure, mechanical failure, magnetic field interference, etc. In addition, friction, load and poor lubrication are also common causes of wear and failure of the antenna rotation mechanism.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0032] Reference Figure 1-Figure 9, including a satellite dish body 1 for reflecting and focusing electromagnetic wave signals and a high-frequency head body 2 for receiving signals, and also including: a mounting frame 3 as a mounting carrier of the satellite dish body 1; a fixing frame 4 is fixedly connected to the mounting frame 3, and two fixing frames 4 are provided. A connecting plate 7 is rotatably connected to the fixing frame 4, and the other end of the connecting plate 7 is fixedly connected to the back of the satellite dish body 1; a connecting main rod 10 is provided between the two fixing frames 4, and a connecting rod 14 and a connecting rod 27 are rotatably connected in the connecting main rod 10, and the side end of the connecting rod 14 is fixedly connected to the connecting plate 7, and the connecting rod 14 and the connecting rod 27 are mutually sleeved together, and the connection part thereof is wrapped in a magnetic A magnetic block 30 is slidably connected inside the magnetic ring 28, a plug rod 31 is provided below the magnetic block 30, and a socket 32 matching with the plug rod 31 is provided on the connecting rod 27; a receiving groove 34 is provided in the fixing frame 4, a turntable 18 is rotatably connected in the receiving groove 34, and a receiving block 12 is fixedly connected to the turntable 18; a driven gear 17 that rotates synchronously with the turntable 18, and an angle sensor 21 is provided below the driven gear 17; arc grooves 8 are provided in both fixing frames 4, and the arc grooves 8 extend into the connecting plate 7, and the two arc grooves 8 are respectively provided with a distance sensor 1 9 and a distance sensor 2 11 matching with the receiving block 12.
[0033] In the present invention, the high-frequency head body 2 is fixed in front of the focus of the satellite dish body 1 by a plurality of fixed support rods arranged on the satellite dish body 1, so that the high-frequency head body 2 can receive the strongest signal, thereby improving the signal receiving efficiency. The high-frequency head body 2 is located at the focus, which can ensure the stability of the received signal quality and reduce the image deformation and interference caused by signal fluctuations.
[0034] When controlling the satellite dish body 1 to rotate and adjust the angle, the plug rod 31 is inserted into the socket 32 on the second connecting rod 27, so that the connecting rod 1 14 and the second connecting rod 27 form a whole rod and rotate synchronously. In the initial state, the plug rod 31 is inserted into the socket 32, the connecting rod 1 14 and the second connecting rod 27 rotate, the connecting rod 1 14 drives the connecting plate 7 to rotate, and the connecting plate 7 drives the satellite dish body 1 to adjust its angle;
[0035] The distance sensor 1 9 and the distance sensor 2 11 are respectively located in the two arc grooves 8, and the arc grooves 8 extend into the connecting plate 7. The depth of the arc grooves 8 extending inward in the connecting plate 7 covers the installation height of the distance sensor 1 9 and the distance sensor 2 11, so that when the connecting plate 7 rotates on the fixing frame 4, the distance sensor 1 9 and the distance sensor 2 11 will not collide with the fixing frame 4. In normal operation, the rotation angle of the satellite dish body 1 is the range of motion of the arc grooves 8;
[0036] The receiving block 12, the distance sensor 1 9 and the distance sensor 2 11 move on three planes respectively, and the three planes are parallel to each other, so the distance between the receiving block 12, the distance sensor 1 9 and the distance sensor 2 11 is a constant value;
[0037] The angles that the connecting rod 14 and the connecting rod 27 need to rotate are uniformly adjusted by the control center. When the driving device controls the connecting rod 14 and the connecting rod 27 to rotate to the required angle, the connecting plate 7 synchronously drives the ranging sensor 1 9 and the ranging sensor 2 11 to move. Similarly, the driving device controls the turntable 18 to rotate, so that the receiving block 12 also rotates to the corresponding position angle. After the rotation is completed, the ranging sensor 1 9 and the ranging sensor 2 11 detect the distance from the receiving block 12 separately or simultaneously. If the values detected by the ranging sensor 1 9 and the ranging sensor 2 11 are the same as the initial state, and are consistent with the angle measured by the angle sensor 21, it means that the rotation angle of the satellite dish body 1 is accurate; if the ranging sensor 1 9 and the ranging sensor 2 11 are consistent with the initial state, the angle of the satellite dish body 1 is accurate. If the values detected by the distance sensor 11 are the same as the initial state, but are inconsistent with the angle measured by the angle sensor 21, it means that the angle sensor 21 fails. In this case, the rotation angle of the satellite dish body 1 is also accurate; if the values detected by the distance sensor 1 9 and the distance sensor 2 11 are different from one or two of the initial state, and the angle values measured by the angle sensor 21 are compared, it can be determined that a certain distance sensor is damaged and failed. In this case, the rotation angle of the satellite dish body 1 is also accurate; if the values detected by the distance sensor 1 9 and the distance sensor 2 11 are different from the initial state, and the angle values measured by the angle sensor 21 are compared, it can be determined that the rotation angle of the satellite dish body 1 is not accurate;
[0038] When it is determined that the rotation angle of the satellite dish body 1 is not accurate, the insertion rod 31 disengages from the socket 32, and the connecting rod 14 and the connecting rod 2 27 are no longer connected as a whole. Since the connecting rod 14 is disengaged from the connecting rod 2 27, the satellite dish body 1 automatically resets under the action of gravity. Through the angle value of the angle sensor 21, the control center controls the connecting rod 14 to rotate to the corresponding position by independently controlling the connecting rod 14. At this time, the ranging sensor 1 9 and the ranging sensor 2 11 continue to detect with the receiving block 12. If the detected values are the same as the initial state, it means that after self-adjustment, the satellite dish body 1 rotates to the corresponding angle to meet temporary emergency communication.
[0039] Reference Figure 1-Figure 9 A through sliding groove 5 is provided on the connecting plate 7 and the fixing frame 4. A sliding rod 6 is provided in the sliding groove 5. Both ends of the sliding rod 6 are fixed to the two connecting plates 7 by nuts.
[0040] In the present invention, when the connecting plate 7 rotates, the sliding groove 5 cooperates with the sliding rod 6, so that the connecting plate 7 can rotate more smoothly on the fixing frame 4.
[0041] Reference Figure 1-Figure 9 A driving motor 13 is provided on the mounting frame 3, and the output end of the driving motor 13 extends to the inside of the connecting main rod 10. The inside of the connecting main rod 10 is hollow. The output end 13 of the driving motor 1 is placed at the end inside the connecting main rod 10 and is fixedly connected with a bevel gear 26. The bevel gear 26 is meshed with a bevel gear 25, and the bevel gear 25 is fixedly connected to the connecting rod 27.
[0042] In the present invention, the driving motor 13 drives the bevel gear 26 to rotate, and the bevel gear 26 drives the bevel gear 1 25 to rotate, so that the connecting rod 27 rotates, thereby controlling the satellite dish body 1 to adjust the angle.

The turntable 18 is a hollow ring, which is convenient for the connecting rod 14 to drive the connecting plate 7 to rotate, and the part of the connecting rod 14 close to the connecting plate 7 is solid;

[0047] In the present invention, when the driving motor 13 rotates inaccurately, the double-headed motor 22 independently controls the connecting rod 14 to rotate through the driving gear 23 and the driven gear 3 24, so that the satellite dish body 1 rotates to the required angle to achieve temporary emergency communication.
[0048] Reference Figure 1-Figure 9A built-in groove 29 is provided in the magnetic ring 28, and the magnetic ring 28 is an electromagnet; a retreat groove 33 is provided on the connecting rod 14, and a hole for the insertion rod 31 to pass through is provided at the bottom of the retreat groove 33; a magnetic block 30 is slidably connected in the built-in groove 29, and the insertion rod 31 is fixedly connected to the bottom of the magnetic block 30, and the magnetic block 30 cooperates with the retreat groove 33.
[0049] In the present invention, the magnetic ring 28 is an electromagnet. When the insertion rod 31 needs to be inserted into the insertion hole 32, the magnetic poles of the magnetic ring 28 are controlled so that the magnetic ring 28 and the magnetic block 30 repel each other, and the magnetic block 30 is repelled into the retreat groove 33, and the insertion rod 31 is inserted into the insertion hole 32, and the connecting rod 1 14 and the connecting rod 2 27 are connected as a whole; when the insertion rod 31 needs to be separated from the insertion hole 32, the magnetic poles of the magnetic ring 28 are controlled so that the magnetic ring 28 and the magnetic block 30 are attracted to each other, the magnetic ring 28 absorbs the magnetic block 30, and the magnetic block 30 drives the insertion rod 31 to separate from the insertion hole 32. At this time, the double-headed motor 22 controls the rotation of the connecting rod 1 14 alone through the driving gear 23 and the driven gear three 24.
