[0019] The end of the detection rod 1 5 is provided with a slope 10, and the end of the detection rod 2 6 is provided with a slope 2 11. The slope 10 and the slope 2 11 match each other. The slope 10 and the slope 2 11 are provided with an induction sensor 1. When the slope 10 and the slope 2 11 are in contact with each other, the induction sensor 1 sends out a signal 1. When the slope 10 and the slope 2 11 are separated, the induction sensor 1 sends out a signal 2.

[0020] Specifically, when the detection rod 1 5 rotates, the inclined surface 10 at its end will gradually contact the inclined surface 2 11 and send out signal 1, which will push the detection rod 2 6 to move. When the detection rod 1 5 moves between the two detection rods 2 6, the inclined surface 10 will separate from the inclined surface 2 11, send out signal 2, and the detection rod 2 6 will automatically reset.

[0021] The detection ring 3 is provided with a groove 12 matching the detection rod 5, the end of the detection rod 5 extends into the interior of the groove 12, a spring 13 is provided on the side wall of the detection rod 5, the end of the spring 13 is fixedly connected to the side wall of the groove 12, and an induction sensor 2 is provided inside the groove 12.

[0024] An insertion groove 14 is provided on the side wall of the detection rod 15, and a slidingly connected insertion piece 15 is provided inside the detection ring 3, and the insertion piece 15 matches the insertion groove 14. An electromagnet 16 is provided on the insertion piece 15 inside the detection ring 3, and a magnet block is provided inside the insertion piece 15; When the electromagnet 16 is energized, the electromagnet 16 generates magnetic force to attract the magnet block in the insertion sheet 15, thereby driving the insertion sheet 15 to move upward, so that the insertion sheet 15 is located above the insertion slot 14; When the electromagnet 16 is powered off, the electromagnet 16 cannot be attracted to the magnet block. Under the action of gravity, the insertion piece 15 will fall, and finally the end of the insertion piece 15 will be inserted into the insertion slot 14.

In a preferred embodiment, the insertion piece 15 can be connected to a reset spring. When falling, the reset spring will generate a certain thrust on the insertion piece 15, so that the insertion piece 15 can be more accurately inserted into the insertion slot 14.

[0025] The transmission assembly 7 includes a transmission rod 71, which is connected to the output shaft of the driving motor 72. The outer wall of the transmission rod 71 is provided with a driving gear 73. The outer wall of the auxiliary ring 4 is provided with an annular rack 1 74, and the driving gear 73 meshes with the annular rack 1 74. The outer wall of the transmission rod 71 is provided with a fan gear 75. The outer wall of the detection ring 3 is provided with an annular rack 2 76, and the annular rack 2 76 meshes with the fan gear 75. The outer wall of the support column 2 is provided with an annular groove, and a ratchet 77 is provided inside the annular groove. The inner wall of the detection ring 3 is provided with a pawl 78 matching the ratchet 77.

[0026] Specifically, the drive motor 72 is started, and the output shaft of the drive motor 72 drives the transmission rod 71 to rotate, the transmission rod 71 drives the driving gear 73 to rotate, the driving gear 73 drives the meshing annular rack 1 74 to rotate, the annular rack 1 74 drives the auxiliary ring 4 to rotate, so that the detection rod 2 6 on the auxiliary ring 4 rotates, thereby controlling the detection rod 2 6 to be used in conjunction with the detection rod 1 5, and the rotation direction of the detection rod 2 6 is opposite to the unidirectional rotation direction of the ratchet 77 and the pawl 78, to ensure that the detection rod 1 5 will not drive the detection ring 3 to rotate when pushing the detection rod 2 6 to move, affecting the use At the same time, the transmission rod 71 will also drive the sector gear 75 to rotate. The sector gear 75 has fewer teeth. During each rotation cycle, the sector gear 75 will mesh with the annular rack 2 76 to drive the annular rack 2 to rotate. At this time, the annular rack 2 76 will drive the detection wheel to rotate. Since the sector gear 75 has fewer teeth, it can only drive the annular rack 2 76 to rotate a smaller angle, and at the same time, the detection wheel will also rotate a smaller angle. At this time, the position of the detection rod 1 5 will be changed, and its relative position with the support column 2 will be adjusted, so that the angles of the support column 2 in all directions can be detected.

[0027] The driving component 9 includes an adjusting ring 91, which is rotatably arranged on the outer wall of the antenna receiving end 1, and the adjusting ring 91 is provided with a hinged knocking rod 1 92 and a knocking rod 2 93. The outer wall of the support column 2 is provided with an elastically hinged dial rod 94, and the dial rod 94 generates a knocking force on the knocking rod 1 92 and the knocking rod 2 93; the dial rod 94 is hinged to the support column 2 through a rotating shaft 95, and the rotating shaft 95 is located between the two end portions of the dial rod 94. A torsion spring is provided on the rotating shaft 95, and the torsion spring is used to control the reset of the dial rod 94. The outer wall of the support column 2 is provided with a transmission ring 9 6. The transmission ring 96 is connected to the auxiliary ring 4. The outer wall of the transmission ring 96 is provided with a toggle tooth 97. The toggle tooth 97 contacts with one end of the dial rod 94 during rotation, and the other end of the dial rod 94 contacts with the knock rod 1 92 and the knock rod 2 93; the end of the knock rod 2 93 is provided with a hinged connecting seat 1 98, and the end of the knock rod 1 92 is provided with a hinged connecting seat 2 99. The connecting seat 1 98 and the connecting seat are fixedly connected to the adjustment ring 91, and a load-bearing ball 910 is provided inside the connecting seat 1 98. The weight of the connecting seat 1 98 is greater than the weight of the connecting seat 2 99.

[0028] Specifically, when the auxiliary ring 4 rotates, it will drive the transmission ring 96 to rotate, and the transmission ring 96 will drive the toggle tooth 97 to rotate. During the rotation, the toggle tooth 97 will contact the dial rod 94 and drive the dial rod 94 to be hinged. When the toggle tooth 97 is separated from the knock rod 1 92 and the knock rod 2 93, the dial rod 94 will be quickly reset under the action of the torsion spring. During the resetting process, one end of the dial rod 94 will hit the knock rod 1 92 and the knock rod 2 93. When the above operation is repeated, the knock rod 1 92 and the knock rod 2 93 will generate vibration force, which will cause the antenna receiving end 1 to generate vibration force to drive away the birds and other animals that have settled there, and it can also cause the debris on the antenna receiving end to fall off, thereby ensuring the normal use of the antenna.

[0029] When the angle of the antenna receiving end 1 is adjusted, since the weight of the connecting seat 1 98 plus the bearing ball 910 is greater than that of the connecting seat 2 99, and under the action of gravity, the connecting seat 1 98 will automatically move to the downward tilted position of the antenna receiving end 1, thereby always keeping the connecting seat 1 98 at the lowest end. At this time, since the connecting seat 1 98 and the connecting seat 2 99 are both connected to the adjustment ring 91, the connecting seat 2 99 will be located in the symmetrical direction of the connecting seat 1 98, that is, the high point of the antenna receiving end 1, so that the knocking rod 1 92 and the knocking rod 2 93 can be distributed on both sides of the antenna receiving end 1, and finally the generated vibration force can be dispersed instead of being limited to a certain part, thereby expanding the monitoring range.

[0030] The working principle of the present invention is as follows: when the antenna is in use, the control driving motor 72 is started, so that the auxiliary ring 4 can rotate, and the auxiliary ring 4 will drive the detection rod 2 6 to rotate during the rotation process. Since the inclined surfaces of the detection rod 2 6 and the end of the detection rod 1 5 match, the detection rod 1 5 will be pushed inward, and the time point when the inclined surface of the detection rod 1 5 is separated from the inclined surface of the detection rod 2 6, and the time point when the detection rod 1 5 is completely fitted with the inner wall of the groove are recorded. If the two time points are the same, it means that the support column 2 has not tilted. If the two time points are different, it means that when the detection rod 1 5 has been fitted with the inner wall, the detection rod 2 6 will also push the detection rod 1 5 to move, thereby proving that the support column 2 is tilted at this time, and And the time node of signal three can be marked on the time axis between signal one and signal two. After intercepting the front section, the time period between the time node of signal three and the time node of signal two remains. At the same time, the tilt amount is calculated according to the rotation rate and the Pythagorean theorem. When the tilt amount reaches the set threshold, the current of the electromagnet 16 is disconnected, so that the insertion piece 15 is inserted into the insertion slot 14, and the detection rod 1 5 is limited and fixed. At this time, after the end of the detection rod 2 6 is completely fitted with the end of the detection rod 1 5, it continues to rotate, and the support column 2 will be pushed to move through the detection rod 2 6 to correct it to make it vertical, and stop the rotation of the drive motor 72. At this time, the support column 2 is supported and fixed to increase the stability of the support column 2.

[0031] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
