DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0038] like Figure 1 As shown, this embodiment provides an antenna omnidirectional automatic tracking system, including a support frame with adjustable height, an adjustment device 2 arranged on the top of the support frame, and an antenna receiver device 3 arranged on the top of the adjustment device.

[0039] It should be noted that the support frame may be a support tripod, a support quadripod, or other structure that can stably support the support frame on a fixed surface.

[0040] In some embodiments, the support frame is a support tripod 1 .

[0041] like Figure 2 As shown, the supporting tripod 1 comprises a top plate, a supporting platform 12 arranged above the top plate, and three supporting legs 13 pivotally fixed to the top plate.

[0042] Specifically, the intervals between the three supporting legs 13 are consistent.

[0043] In some embodiments, each support leg 13 includes a first leg tube 131 , a second adjustable leg tube 132 , and a third adjustable leg tube 133 .

[0044] Specifically, each support leg 13 has two sleeves 14 .

[0045] The upper end of the first leg tube 131 is pivotally arranged on the top plate, the lower end of the third adjustable leg tube 133 is supported on a fixed surface such as the ground, the upper end of the second adjustable leg tube 132 is sleeved with the lower end of the first leg tube 131 through the first sleeve 141, and the lower end of the second adjustable leg tube 132 is sleeved with the upper end of the third adjustable leg tube 133 through the second sleeve 142.

[0046] The second adjustable leg tube 132 and the third adjustable leg tube 133 can slide in the corresponding sleeves. Therefore, the height and placement level of the supporting tripod 1 can be changed by adjusting the second adjustable leg tube 132 and the third adjustable leg tube 133 according to actual needs.

[0047] Specifically, the top plate on the supporting tripod 1 is connected to the first leg tubes 131 of the three supporting legs 13, and the opening and closing angles of the three supporting legs 13 can be adjusted, thereby adjusting the overall height of the supporting tripod 1. The supporting tripod 1 can also be folded for easy carrying.

[0048] In some embodiments, a fixing platform 15 fixedly connected to the supporting platform 12 is disposed on the top of the supporting tripod 1. A rotating shaft 151 is disposed at the center of the fixing platform 15.

[0049] Specifically, the rotating shaft 151 is cylindrical.

[0050] like Figure 4-5 As shown, the adjustment device 2 includes a first pivoting portion 21, a second pivoting portion 22 disposed on the top of the first pivoting portion 21, and a motor drive mechanism.

[0051] Specifically, the first pivoting portion is a cube that can automatically rotate 360° in all directions.

[0052] like Figure 3 As shown, a rotation hole matching the rotation axis 151 is provided at the bottom center of the first pivoting portion 21. The first pivoting portion 21 is fixed to the fixed platform 15 via the rotation axis 151, so that the first pivoting portion 21 automatically rotates 360° in the horizontal direction around the rotation axis 151 under the drive of the motor driving mechanism.

[0053] The second pivoting portion 22 is pivotally connected to the first pivoting portion 21 via at least one adjusting hinge 221 , so that the second pivoting portion 22 moves relative to the first pivoting portion 21 in a vertical direction around the adjusting hinge 221 .

[0054] It should be noted that the adjustment hinge 221 can be disposed at the center or at two sides of the first pivoting portion 21 .

[0055] In some embodiments, an adjustment hinge 221 is respectively disposed on two sides of the first pivoting portion 21. The second pivoting portion 22 is pivotally connected to the first pivoting portion 21 through two adjustment hinges 221, so as to achieve rotation adjustment and fixation of the second pivoting portion within a range of 90° in the vertical direction under the drive of the motor drive mechanism.

[0056] In some embodiments, a platform 23 higher than the top of the first pivoting part 21 is provided on the top of the second pivoting part 22 for placing the antenna receiver device 3, and the platform 23 moves with the movement of the second pivoting part 22 in the vertical direction, with an adjustment range of 0-90°, thereby ensuring precise control of the vertical angle of the antenna 32 placed thereon.

[0057] Specifically, the upper surface of the platform 23 is in the shape of a rectangle.

[0058] like Figure 6-7 As shown, the antenna receiver device 3 includes a receiver 31 , an antenna 32 arranged on the top of the receiver 31 , and a connecting plate 321 for fixing the antenna 32 .

[0059] The receiver 31 is used to analyze the signal received by the antenna 32 and then output instructions to the motor drive mechanism.

[0060] The motor drive mechanism receives the instructions output by the antenna and adjusts the directions of the first pivot part 21 and the second pivot part 22 according to the instructions, so that the first pivot part 21 automatically rotates 360° in the horizontal direction around the rotation axis 151 under the drive of the motor drive mechanism, and the second pivot part 22 moves 90° in the vertical direction relative to the first pivot part 21 around the adjustment hinge.

[0061] In some embodiments, the receiver 31 and the platform 23 of the second pivoting portion 22 are connected by threads to achieve separation and installation of the antenna receiver device 3 and the adjustment device 2 .

[0062] Preferably, the receiver 31 and the platform 23 of the second pivoting part 22 are connected by bolts. A bolt 311 is provided at the bottom of the receiver 31, and a thread 231 is provided at a corresponding position of the platform 23 of the second pivoting part 22.

[0063] Specifically, the receiver 31 is a rectangular box. Bolts 311 are arranged at the four corners of the bottom of the receiver 31 , and corresponding threads 231 are also arranged at the four corners of the platform 23 .

[0064] The working process of the antenna omnidirectional automatic tracking system provided in this embodiment is as follows:

[0065] The supporting tripod 1, the adjustment device 2 and the antenna receiver device 3 are assembled and placed on the ground. The antenna receiver device 3 and the fixed platform 15 connected to the adjustment device 2 are both provided with multiple input terminals or output terminals, and the two are connected by wires. The antenna receiver device 3 first scans the radio signal in the air within the range of 360° in the horizontal direction and 90° in the vertical direction. Once the radio signal is captured and tracked, the radio signal is locked and the signal is analyzed. The direction, angle and height of the radio signal are obtained by analysis and calculation: the first pivot part 21 and the second pivot part 22 adjust the directivity in the horizontal and vertical directions according to the direction, angle and height of the transmitted radio signal, so as to realize the all-round automatic tracking of the radio signal by the antenna.

[0066] In summary, the solution proposed by the utility model has the following technical effects:

[0067] The utility model can drive the motor driving mechanism to automatically adjust the antenna according to the result output by the receiver, so as to achieve accurate adjustment of the antenna angle and realize automatic search and tracking of radio signals within the range of 360° in the horizontal direction and 90° in the vertical direction, and the system has a simple structure and flexible adjustment.

[0068] Please note that the technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of this application, which all belong to the protection scope of this application.
