As an embodiment of the present invention, the dial frame 41 includes a movable plate 411 and a contact rod 412, two ends of the contact rod 412 are respectively connected to the movable plate 411, and the contact rod 412 is in contact with the bottom of the secondary antenna 3; the lower end of the push rod 71 is of a hemispherical structure and is used for contacting the driving shifting plate 43 at different inclination angles; during operation, level sub-antenna 3 is at the pivoted in-process, contact rod 412 changes with level sub-antenna 3's contact position, contact rod 412's rod-shaped structure can prevent to produce the scratch to level sub-antenna 3 bottom friction great, avoid leading to contact rod 412 and level sub-antenna 3's area of contact to change because of the change of level sub-antenna 3 angle, make level sub-antenna 3's atress comparatively stable, and then make level sub-antenna 3 undulant steadily in the precision of posture change front and back, improve the inside relative stability of cooling in-process of base station antenna.

The specific working process is as follows:

when the antenna housing 1 is exposed to the external environment for a long time, the outside heat and the inside heat of the antenna housing 1 tend to rise slowly, in this process, the shunt guide rod 91 in the heat conducting assembly 9 contacts with the antenna housing 1 and the back plate 2, so that the outside heat and the inside heat of the antenna housing 1 are guided to the shunt guide rod 91, the heat is conducted to the heat conducting wires 92 at two sides through the shunt guide rod 91, the heat conducting efficiency can be further improved, the heat conducting wires 92 are connected with the heat dissipation core rod 61, so that the heat can be further conducted, and because the heat dissipation core rod 61 is arranged inside the clasping column 6, the bottom of the heat dissipation core rod 61 is buried underground along with the clasping column 6, so that the heat at the upper part of the heat dissipation core rod 61 is conducted to the underground environment with relatively low temperature, thereby maintaining the stable temperature inside the heat dissipation core rod 61 under the heat compensation exchange, and guiding the heat to the heat dissipation core 61 through the heat conducting wires 92, the whole heat dissipation process can be continuously carried out, the whole heat dissipation efficiency is improved, as the base station antenna continuously works for a long time, the heat inside the antenna shell 1 continuously rises even to ninety degrees, when the alcohol filled inside the rubber column 53 in the induction component 5 reaches the boiling point temperature, the inner space of the rubber column 53 expands outwards, as the upper side of the rubber column 53 is shielded by the sealing cover 52, the expansion of the rubber column 53 is guided to the lower side, namely the rubber column 53 expands integrally and simultaneously pushes the push rod 71 in the moving component 7 to move, at the moment, the push rod 71 can move downwards, so that the active poking plate 43 in the angle adjusting component 4 is driven to rotate downwards, as the active poking plate 43 rotates coaxially with the poking frame 41, the poking frame 41 rotates upwards while the active poking plate 43 rotates downwards, as the contact rod 412 in the poking frame 41 is connected with the bottom of the secondary antenna 3, the stage sub-antenna 3 can be driven by the dial frame 41 to rotate upwards, at the moment, the distance between the stage sub-antenna 3 and the back plate 2 changes, the base station antenna changes the signal frequency band of gain, the service load of the base station antenna on working frequency band signals is reduced, the physical resource blocks are reduced, the power consumption of a signal power amplifier is reduced, the heat generated by the working of the base station antenna is reduced, at the moment, the heat inside the antenna shell 1 slowly drops, then the rubber column 53 also restores the original state along with the drop of the heat, and then the push rod 71 moves upwards under the drive of the tension spring 73, the dial frame 41 and the active dial plate 43 in the angle adjusting component 4 restore the balance, the base station antenna can continuously and effectively work, and meanwhile, the heat dissipation efficiency of the base station antenna is improved in the whole process.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
