Description

Technical Field

[0001] This utility model relates to the field of log-periodic antennas, and specifically to a log-periodic antenna rotation platform. Background Technology

[0002] Log-periodic antennas, as a type of broadband directional antenna, are widely used in communications, radar monitoring, and broadcast television signal reception due to their excellent impedance matching characteristics and pattern stability in shortwave and ultra-shortwave bands. To ensure that the log-periodic antenna (5) can be accurately aligned with the signal source and improve signal reception / transmission efficiency, a corresponding rotation adjustment device is required to adjust the antenna angle in the horizontal or pitch direction. This device is the log-periodic antenna rotation platform.

[0003] Existing technologies simply use a motor and a reduction gear to drive the antenna rotation, and rely on sensors and a control system to achieve automatic angle positioning. While such platforms offer high adjustment precision and ease of operation, they are electrically powered and prone to failure in the field due to motor malfunctions, resulting in reliability issues.

[0004] Therefore, it is very necessary to provide a log-periodic antenna rotation platform to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides a log-periodic antenna rotation platform to solve the problem that the existing technology, which simply uses a motor and a reduction mechanism to drive the antenna rotation, is prone to failure when the motor fails, resulting in a short reliability.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A log-periodic antenna rotation platform includes a support member and a rotation adjustment member connected to the support member. The rotation adjustment member includes an automatic rotation member and a manual rotation member. An antenna is connected to the rotation adjustment member, and an antenna rotating rod is connected to the lower end of the antenna. Both the automatic rotation member and the manual rotation member are used to adjust the rotation angle of the antenna. The automatic rotation member includes a rotation motor connected to the support member. The rotating end of the rotation motor is connected to an irregular protrusion. A locking rod is engaged on the irregular protrusion, and the locking rod is rotatably connected to the antenna rotating rod. The manual rotation member includes a manual handle rotatably connected to the support member and a first pulley connected to the manual handle. A belt body is connected to the first pulley, and a second pulley is connected to the locking rod. The belt body is connected to the second pulley.

[0007] Furthermore, the support member adopts a two-stage telescopic rod.

[0008] Furthermore, a manual hydraulic pump is connected to the support member.

[0009] Furthermore, a housing is connected to the support member, and the antenna rotating rod is rotatably connected to the housing.

[0010] Furthermore, a telescopic hydraulic cylinder is connected to the housing. The telescopic end of the telescopic hydraulic cylinder is connected to the rotating motor. The telescopic hydraulic cylinder is used to extend during manual adjustment so that the irregular protrusion on the rotating motor moves away from the locking rod. The telescopic hydraulic cylinder is used to retract during automatic adjustment so that the irregular protrusion on the rotating motor engages with the locking rod.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0012] By incorporating both automatic and manual adjustment mechanisms, the flexibility of antenna angle adjustment is significantly enhanced. The automatic adjustment mechanism, driven by a rotary motor, can quickly and accurately adjust the antenna angle according to a preset program or remote command, eliminating the need for manual on-site operation. This is particularly suitable for scenarios requiring frequent antenna angle adjustments to adapt to different signal environments or meet automated communication needs, such as unattended communication base stations and field mobile communication equipment, effectively saving labor costs and improving adjustment efficiency. The manual adjustment mechanism provides a backup method for special situations such as automatic adjustment failure, insufficient power supply, or the need for fine-tuning. Users can directly control the antenna angle via a manual throttle, ensuring effective antenna adjustment under any circumstances and guaranteeing communication stability and reliability. This solves the problem of existing technologies that rely solely on a motor and reduction gear mechanism to drive antenna rotation, which are prone to malfunctions and reliability issues when the motor fails.

Its height can be adjusted according to the usage scenario. The lower end can be fixed to the ground or a mounting base, while the upper end connects to the rotation adjustment component 2 and other auxiliary components, such as the manual hydraulic pump 14 and the housing 15.
