Description

Technical Field

[0001] The utility model relates to the technical field of communication technologies, and particularly relates to an anti-interference satellite navigation receiver. Background Art

[0002] A satellite navigation receiver is an instrument that receives global positioning system satellite signals and determines the ground and spatial positions. The navigation and positioning signals sent by satellites are an information resource that can be shared by countless users. For users on land, at sea, and in space, they have receiving devices that can receive, track, transform, and measure GNSS signals.

[0003] Most of the antennas of existing satellite navigation receivers are fixed. Since satellites are constantly revolving around the earth, the signals of fixed antennas cannot change their orientations, which will affect the signal reception intensity. Moreover, satellite navigation receivers are susceptible to intentional or unintentional interference signals on the ground and in the near-earth space. When the signal reception intensity is low, signal loss is likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-interference satellite navigation receiver to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An anti-interference satellite navigation receiver, including a base. A turntable is arranged on the top of the base. A toothed opening is arranged at the bottom end of the turntable. A driving gear is meshed with the outer surface of the toothed opening. A supporting vertical rod is arranged at the top end of the turntable. Two support rods are arranged at the top end of the supporting vertical rod. A cushion block is fixedly connected and installed at the top of the two support rods. A measuring antenna is arranged at the top end of the cushion block. An adjusting ring is arranged at the top end of the cushion block. A supporting link is arranged on each side of the adjusting ring. A pull rod is hinged and installed at the bottom of the two supporting links. Electric push rods are hinged and installed in the middle sections of the two pull rods.

[0006] Preferably, the bottom ends of the two electric push rods are jointly connected to the top surface of the turntable, fixing the bottoms of the two electric push rods, so that the two electric push rods will pull or push the pull rod when running.

[0007] Preferably, fixing frames are hinged and installed at the tops of the two support rods. One side of each of the two fixing frames is fixedly connected to the two side surfaces of the adjusting ring. The two fixing frames connect the tops of the support rods to the adjusting ring. When the two support rods move, they will drive the adjusting ring to tilt to adjust the elevation angle of the measuring antenna.

[0008] Preferably, a fixed insertion column is arranged at the bottom end of the toothed opening. The bottom of the fixed insertion column is inserted into the base. The fixed insertion column is rotationally connected to the base, ensuring that the toothed opening can rotate without falling off.

[0009] Preferably, positioning frames are hingedly installed at the bottoms of the two pull rods, and one sides of the two positioning frames are fixedly installed on the two side surfaces of the support vertical rod, connecting the bottom of the pull rod to the support vertical rod. When the pull rod is driven by the electric push rod, it will rotate around the positioning frame.

[0010] Preferably, two mounting blocks are provided at the bottom edges on both sides of the base, and a connection port is provided at the front end of the base. The base contains an FFT module, which has the advantages of high algorithm efficiency and good anti-interference performance. When installing the satellite navigation receiver, the device is fixedly installed at a high position through the mounting blocks.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For this anti-interference satellite navigation receiver, when the elevation angle of the measurement antenna is adjusted by the cooperation of the turntable and the electric push rod, when the output end of any one electric push rod extends, it will push the corresponding pull rod, and when the output end of the other electric push rod retracts, it will pull the corresponding pull rod, causing the corresponding support link to rotate, so as to drive the adjustment ring to tilt to one side. At this time, the measurement antenna will tilt to facilitate better signal reception. When the measurement antenna tilts, the low-speed motor drives the gear to rotate, driving the tooth opening to rotate and the turntable to rotate, adjusting the orientation of the measurement antenna, enabling the measurement antenna of the satellite navigation receiver to change its orientation, enhancing the reception of electromagnetic signals emitted by satellites during revolution, and avoiding interference, whether intentional or unintentional, from the ground and near-earth space that affects signal reception.

[0019] As Figures 1 to 3 shown, the anti-interference satellite navigation receiver in this embodiment includes a base 1. A turntable 4 is provided on the top of the base 1. A tooth opening 15 is provided at the bottom end of the turntable 4. The outer surface of the tooth opening 15 is meshed with a driving gear 14. A low-speed motor is provided at the bottom of the driving gear 14. When the driving gear 14 rotates, it drives the tooth opening 15 to rotate. A support vertical rod 16 is provided at the top end of the turntable 4. Two support rods 13 are provided at the top end of the support vertical rod 16. A cushion block 12 is fixedly connected and installed at the top of the two support rods 13. An adjusting ring 11 is provided at the top end of the cushion block 12. A measuring antenna 5 is provided at the top end of the adjusting ring 11. The cushion block 12 can be flipped on the top of the support rod 13 to change the elevation angle of the measuring antenna 5. Support connecting rods 9 are provided on both sides of the adjusting ring 11. A pull rod 8 is hinged and installed at the bottom of the two support connecting rods 9. Electric push rods 6 are hinged and installed in the middle sections of the two pull rods 8. The two electric push rods 6 will operate alternately. When the output end of any one of the electric push rods 6 extends, it will push the corresponding pull rod 8, and when the output end of the other electric push rod 6 retracts, it will pull the corresponding pull rod 8, causing the corresponding support connecting rod 9 to flip, so as to drive the adjusting ring 11 to tilt to one side.

[0020] Specifically, the bottom ends of the two electric push rods 6 are jointly connected to the top surface of the turntable 4 to fix the bottoms of the two electric push rods 6, so that the two electric push rods 6 will pull or push the pull rod 8 during operation.

[0021] Further, fixed brackets 10 are hingedly installed at the tops of both struts 13. One side of each of the two fixed brackets 10 is fixedly connected to both side surfaces of the adjusting ring 11. The two fixed brackets 10 connect the tops of the struts 13 to the adjusting ring 11. When the two struts 13 move, they will drive the adjusting ring 11 to tilt, so as to adjust the elevation angle of the measuring antenna 5.

[0022] Further, a fixed plug post 17 is provided at the bottom end of the tooth opening 15. The bottom of the fixed plug post 17 is inserted into the base 1, and the fixed plug post 17 is rotatably connected to the base 1, ensuring that the tooth opening 15 can rotate and will not fall off.

[0023] Further, positioning brackets 7 are hingedly installed at the bottoms of both pull rods 8. One side of each of the two positioning brackets 7 is fixedly installed on both side surfaces of the support vertical rod 16, connecting the bottoms of the pull rods 8 to the support vertical rod 16. When the pull rods 8 are driven by the electric push rods 6, they will flip around the positioning brackets 7 as the center.

[0024] Furthermore, two mounting blocks 2 are provided at the bottom edges on both sides of the base 1. A connection port 3 is provided at the front end of the base 1. The base 1 contains an FFT module, which has the advantages of high algorithm efficiency and good anti-interference performance. When installing the satellite navigation receiver, the device is fixedly installed at a high place through the mounting blocks 2.

[0025] The usage method of this embodiment is as follows: When the satellite navigation receiver is installed at a high place, the signal is received through the measuring antenna 5. When receiving the signal, since the satellite will revolve around the earth, the signal reception intensity of the measuring antenna 5 is different at different positions of the satellite. To ensure the signal reception of the measuring antenna 5, the orientation angle of the measuring antenna 5 needs to be adjusted at different times. When adjusting the elevation angle of the measuring antenna 5, when the output end of any one of the electric push rods 6 extends, it will push the corresponding pull rod 8, and when the output end of the other electric push rod 6 retracts, it will pull the corresponding pull rod 8, causing the corresponding support link 9 to flip, so as to drive the adjusting ring 11 to tilt to one side. At this time, the measuring antenna 5 will tilt to facilitate better signal reception. When the measuring antenna 5 tilts, the low-speed motor drives the gear 14 to rotate, which drives the tooth opening 15 to rotate, causing the turntable 4 to rotate, and adjusting the orientation of the measuring antenna 5.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
