Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a shipborne whip antenna. Background Art

[0002] Shipborne antennas play a vital role on warships, especially aircraft carriers. Shipborne antennas are responsible for receiving and sending radio signals to ensure smooth communication between aircraft carriers and carrier-based aircraft, other warships and ground command posts. These antennas use high-frequency radio waves for communication, have a faster transmission rate and a longer transmission distance, and can transmit various combat commands and intelligence information in real time and accurately. Shipborne antennas are installed high on the ship and are prone to bad weather when sailing at sea. In the face of bad weather, traditional shipborne antennas lack storage structures or storage equipment, and cannot be folded and stored for protection in a timely and safe manner. It takes a long time to repair the broken antenna, which affects the reception and transmission of radio signals and is in urgent need of improvement. Therefore, we propose a shipborne whip antenna.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-3As shown, the utility model provides a technical solution: a shipborne whip antenna, comprising an antenna segment A1, an antenna segment B2 and an antenna segment C3 which are nested in sequence from top to bottom, the inner bottom end of the antenna segment A1 is connected to the inner bottom end of the antenna segment B2 through a spring A12, the inner bottom end of the antenna segment B2 is connected to the inner bottom end of the antenna segment C3 through a spring B13, the bottom of the antenna segment C3 is fixedly connected to the U-shaped seat 9 through a flange seat 8, a base 6 is fixedly arranged on one side of the flange seat 8, a winding mechanism 5 is arranged on the top of the base 6, and the winding mechanism 5 is arranged on the top of the base 6. The structure 5 includes a winding drum 501 and a motor 502 for driving the winding drum 501 to rotate. The surface of the winding drum 501 is connected to one end of the pull rope 4. The other end of the pull rope 4 passes through the antenna segment C3 and is connected to the top of the inner wall of the antenna segment A1. The bottom of the U-shaped seat 9 is connected to the falling mechanism. The falling mechanism includes a reducer 10 and a driving motor 11. The power output end of the reducer 10 is connected to the U-shaped seat 9. The spring A12 is located above the spring B13. The distance from the bottom end of the spring A12 to the top end of the spring B13 is set to 4 cm.

[0020] In a specific embodiment of the present utility model, after the antenna segment A1, the antenna segment B2, and the antenna segment C3 are sequentially installed, the top end of the spring A12 is fixed to the bottom end of the inside of the antenna segment A1 by bolts, and the bottom end of the spring A12 is fixed to the bottom end of the inside of the antenna segment B2 by bolts, and then the top end of the spring B13 is fixed to the bottom end of the inside of the antenna segment B2 by bolts, and the bottom end of the spring B13 is fixed to the bottom end of the inside of the antenna segment C3 by bolts, and then the long cover 7 is assembled at the openings of the antenna segment A1, the antenna segment B2, and the antenna segment C3. When the spring needs to be replaced later, it is only necessary to remove the corresponding long cover 7 and the corresponding bolts to replace the spring. The control of the drive motor 11 and the motor 502 are controlled by an independent controller, and the controller is remotely connected to the drive motor 11 and the motor 502 through a wire to realize remote control of the action of the drive motor 11 and the motor 502. Under normal circumstances Spring A12 and spring B13 are in an extended state, so that antenna segment A1, antenna segment B2, and antenna segment C3 are in an extended and extended state. When antenna segment A1 and antenna segment B2 need to be stored, the pull rope 4 is driven to contract by controlling the motor 502 to rotate forward, so that antenna segment A1 is stored inside antenna segment B2, and antenna segment B2 is stored inside antenna segment C3. At this time, spring A12 and spring B13 are in a compressed energy storage state. When the extended state of antenna segment A1, antenna segment B2, and antenna segment C3 needs to be restored, it is only necessary to control the motor 502 to rotate reversely to send the pull rope 4, and the rebound force of spring A12 and spring B13 restores antenna segment A1, antenna segment B2, and antenna segment C3 to the extended state, and the drive motor 11 is controlled to drive the reducer 10 to drive the U-shaped seat 9 to rotate an angle, thereby adjusting the angle of the antenna segment, or the vertical and horizontal lying states of the antenna segment can be switched, which is convenient for the storage and maintenance of the antenna.

[0021] In the preferred technical solution, the surfaces of the antenna segment A1, the antenna segment B2 and the antenna segment C3 are all detachably mounted with long covers 7 by means of bolts, and the long covers are provided to facilitate the installation, removal and replacement of the springs.

[0022] In the preferred technical solution, a guide roller mechanism 14 for guiding the movement of the pull rope 4 is provided on the inner wall of the antenna segment C3. The guide roller mechanism 14 includes a guide roller in rolling contact with the pull rope 4 and a bracket supporting the guide roller. The guide roller mechanism 14 is used to guide the pull rope 4 to roll smoothly at a right-angle corner.

[0023] In the preferred technical solution, a push ring 101 is integrally formed at the top of the outer portion of the antenna segment A1. The outer diameter of the push ring 101 is 1 cm larger than the outer diameter of the antenna segment B2. The push ring 101 is used to prevent the antenna segment A1 from continuing to move downward after being stored inside the antenna segment B2. The push ring 101 plays a limiting role.

[0024] To summarize, this embodiment provides a structure for realizing the electric storage and extension of a multi-section antenna, and at the same time provides a folding device to realize the antenna angle adjustment and vertical and horizontal folding state adjustment functions. The foldable structural design is adopted. The foldable structural design makes the antenna easy to carry, highly reliable, and easy to maintain.
