[0002] For other horn antennas such as double-ridge horn antennas, when various tests are carried out using the horn antenna, it is necessary to accurately aim the receiving antenna at the transmitting antenna to ensure the maximum received power. In actual test projects, accurately aligning the receiving antenna with the microwave signal transmitter is a very time-consuming task, especially when the distance between the transmitting antenna and the receiving antenna is relatively far.

[0003] Generally, the horn antenna is fixed on the antenna support through a mounting seat. When aligning the horn antenna, a sensor is installed on the side wall of the antenna support. By installing a transmitting sensor and a receiving sensor on the receiving antenna and the transmitting antenna respectively, the antenna is aligned through the sensors. However, since the alignment of the receiving antenna and the transmitting antenna requires the alignment of their center lines, and the sensors are installed on the side wall of the antenna support, it is easy to cause the directions of the sensors and the antenna to be non-parallel, resulting in a situation where even though signals can be received between the sensors, the center lines of the transmitting antenna and the receiving antenna are not aligned.

[0028] The present utility model will be described in detail below by referring to the drawings and in combination with the embodiments:

[0029] Embodiment 1:

[0030] As Figures 1 to 2As shown in the figure, this embodiment provides an alignment device for a horn antenna 2, which includes an antenna bracket 1 for fixing the horn antenna 2, a support base 3, a support assembly 5, and a fixed base 6. An installation groove for fixing the sensor 4 is provided at the center of the support base 3. The opening direction of the installation groove is parallel to the center line of the horn antenna 2 on the same straight line. The antenna bracket 1 and the support base 3 are fixedly connected. One end of the support assembly 5 fixedly supports the support base 3, and the other end is fixed on the fixed base 6. In order to ensure that the installation groove of the support base 3 is parallel to the center line of the horn antenna 2, it is necessary to ensure the stability of the antenna bracket 1 and the horn antenna 2. Then, the mounting seat 11 of the antenna bracket 1 is designed as a disc mounting seat 11 of the same size as the support base 3. The support rod of the antenna bracket 1 is vertically installed at the centers of the support base 3 and the mounting seat 11. Then, the horn antenna 2 is vertically installed with the support rod. When fixing, since the support base 3 and the mounting seat 11 of the antenna bracket 1 are fixed and limited by nuts and screws distributed along the circumference of the support base 3, in order to facilitate the alignment of the installation directions of the horn antenna 2 and the sensor 4, fixing screw holes can be provided around the installation groove, so that the installation position can be positioned and limited, making it easier to align.

[0031] When the existing sensor 4 is installed, it is directly fixed on the side wall of the lifting rod. This easily causes the connection line between the center lines of the transmitting antenna and the receiving antenna to be not parallel to the connection line between the transmitting sensor 4 and the receiving sensor 4, resulting in inaccurate calibration between the antennas.

[0032] In this embodiment, the sensor 4 is a laser sensor 4. In order to achieve the alignment between the transmitting antenna and the receiving antenna, the laser sensor 4 is also divided into a receiving sensor 4 and a transmitting sensor 4, which are respectively installed on the alignment devices of the transmitting antenna and the receiving antenna. In this application, only the installation method of the laser sensor 4 is set, that is, the installation methods of the laser sensor 4 on the alignment devices of the transmitting antenna and the receiving antenna are the same, and both adopt the installation method proposed in this embodiment at the center of the support base 3 and parallel to the center line of the antenna on the same straight line.

[0033] Specifically, as Figures 2 - 3 shown, the installation groove includes a cover plate groove 33, a wire groove 34, and a clamping groove 31. The wire groove 34 and the clamping groove 31 are in the same plane. The clamping groove 31 and the cover plate groove 33 are in a stepped shape. The sensor 4 is clamped in the clamping groove 31. The wire groove 34 is used for clamping the control line 71 connected to the sensor 4. The cover plate groove 33 is used for fixing the cover plate 32. The cover plate 32 is embedded in the cover plate groove 33 and is parallel to the surface of the support base 3. The wire groove 34 and the clamping groove 31 are under the cover plate groove 33 and present a stepped shape. The cover plate 32 and the installation groove jointly limit the sensor 4 and the control line 71.

[0034] As Figure 5As shown, the support assembly 5 includes a lifting assembly (adjustable in the height direction). One end of the lifting assembly is fixedly connected to the support base 3, and the other end is fixedly connected to the fixed base 6. Specifically, the lifting assembly includes an electric lifting rod 51 and a lifting rod control box 52. One end of the electric lifting rod 51 can be fixedly connected to the support base 3 through a bearing, and the other end is connected to the electric drive device in the lifting rod control box 52. The bottom of the lifting rod control box 52 is fixedly connected to the fixed base 6 through bolts. In this embodiment, the lifting rod control box 52 can control the up and down movement of the lifting rod through common methods. For example, a motor is installed in the lifting rod control box 52, and it is a common design that the motor drives the electric lifting rod 51 to move, which will not be elaborated in this application.

[0035] The control of the laser sensor 4 is carried out through the control box, and it also includes a sensor control box 7. The sensor control box 7 is fixedly connected to the fixed base 6 through bolts. A control line 71 is led out from the sensor control box 7 and connected to the sensor 4 along the support assembly 5. It can be seen from the figure that both ends of the control line 71 are straight lines and are respectively connected to the sensor 4 and the sensor control box 7, and the straight line parts are fixed to the side wall of the lifting rod through wire clips 8. The middle part of the control line 71 is a spiral line 72, and the central part of the control line 71 is in a spiral shape along the axis of the lifting rod. It can be seen that the side wall of the lifting rod control box 52 is fixedly connected to the sensor control box 7 through bolts.

[0036] As Figure 4 shown, wire clips 8 for fixing the control line 71 are provided on the side wall of the lifting rod. The wire clip 8 includes a fixing block 81. The fixing block 81 is fixedly connected to the side wall of the lifting rod through bolts. A wire passing hole 82 for the control line 71 to pass through is formed on the fixing block 81. The diameter of the wire passing hole 82 matches the diameter of the control line 71, and it can just pass through the straight line part of the control line 71 and then clamp the control line 71.

[0037] To facilitate the fixation of the fixed base 6, a plurality of anchor bolts 61 are fixed on the fixed base 6. The plurality of anchor bolts 61 are evenly distributed along the perimeter of the fixed base 6. There are four anchor bolts 61, and the four anchor bolts 61 are evenly distributed along the four sides of the fixed base 6. The top ends of the anchor bolts 61 are fixed with handwheels 62 through nuts, which is convenient for disassembly. And casters 63 are installed at the four corners of the fixed base 6. This facilitates the movement of the alignment device.

[0038] The usage process of this embodiment is as follows:

[0039] According to the alignment device of the present application, a transmitting sensor 4 is fixedly installed at the center of the support base 3 at the bottom of the antenna support 1 on the transmitting antenna side, and a receiving sensor 4 is fixedly installed at the center of the support base 3 at the bottom of the antenna support 1 on the receiving antenna side. Since the opening direction of the installation groove is parallel to the center line direction of the horn antenna 2, after the sensor 4 is installed in the installation groove, the fixing cover plate 32 is fixed. Then, the screw holes of the mounting seat 11 of the antenna support 1 are aligned with the screw holes on the support base 3, and then the horn antenna 2 and the antenna support 1 are fixed on the support base 3. At this time, it can be ensured that the installation direction of the sensor 4 is parallel to the center line of the horn antenna 2. Then, first, the height between the transmitting antenna and the receiving antenna is adjusted up and down by the electric lifting rod 51. After adjusting to the same height, the sensor 4 on the transmitting antenna side is controlled to emit laser, and the sensor 4 on the receiving antenna side receives the laser. If the laser can be successfully received, it means that the center lines of the transmitting antenna and the receiving antenna are aimed and aligned.

[0040] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
