Description

Technical Field

[0001] The invention relates to the technical field of antenna installation, and in particular to a high-power microwave antenna deployment and collection device. Background Art

[0002] In high-power microwave equipment, the unfolding and folding of the antenna is a key factor in ensuring the performance of the equipment during transportation, storage and operation. Traditional microwave antenna designs usually do not have the function of unfolding and folding, which results in a large overall size of the antenna. Not only does it take up a lot of space during transportation and storage, but in some special application environments, such as small spaces or complex terrain, the installation and use of the antenna is greatly restricted. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems by providing a high-power microwave antenna deployment and retraction device, which aims to solve the problem that the existing microwave antenna has no deployment and retraction design and is bulky in overall size, and to provide a high-power microwave antenna deployment and retraction device with a compact structure, small size and high space utilization. The mechanism can fold the antenna during transportation and storage without reducing the radiation area of ​​the antenna, thereby improving the transportation and storage efficiency of the equipment, and can be quickly deployed during use to ensure the performance of the antenna.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A high-power microwave antenna deployment and retraction device comprises an antenna unit, a deployment and retraction mechanism and a support frame, wherein the antenna unit is rotatably connected to the support frame via the deployment and retraction mechanism; the antenna unit is a planar plate-like structure, and the antenna unit is connected to the deployment and retraction mechanism via a deployment and retraction arm, and the deployment and retraction mechanism can act on the deployment and retraction arm and drive the deployment and retraction arm to rotate around the support frame; an inclined angle of 45 degrees is formed between the deployment and retraction arm and the antenna unit.

[0006] Due to the adoption of the above technical solution, the antenna unit can be flexibly rotated through the unfolding and retracting mechanism. The design of the 45-degree tilt angle between the unfolding and retracting arm and the antenna unit makes it possible for the antenna unit to be located on one side of the support frame and parallel to the plane where the support frame is located when the antenna unit is in the retracted state, occupying less space and facilitating transportation and storage. At the same time, when the antenna unit is in the unfolded state, the antenna unit can be horizontally located above the support frame to ensure the signal reception and transmission performance.

[0007] Furthermore, at least a pair of antenna units are relatively arranged on both sides of the support frame, and the deployment mechanism can drive the paired antenna units to switch between an deployed state and a retracted state. When the antenna units are in the deployed state, the paired antenna units are located in the same plane; when the antenna units are in the retracted state, the paired antenna units are located on both sides of the support frame and are parallel to the plane where the support frame is located.

[0008] Due to the adoption of the above technical solution, the paired antenna units are relatively arranged on both sides of the support frame, which can achieve synchronous storage on both sides and a more compact structure.

[0009] Furthermore, the deployment and retraction mechanism includes a deployment and retraction worm, a deployment and retraction turbine, a deployment and retraction drive motor and a connecting shaft, at least a pair of connecting shafts are arranged relatively on both sides of the deployment and retraction worm, the connecting shaft is provided with a deployment and retraction turbine engaged with the deployment and retraction worm, the deployment and retraction drive motor is connected to and acts on the deployment and retraction worm, and the deployment and retraction worm can make the connecting shafts on both sides rotate synchronously through the deployment and retraction turbine under the action of the deployment and retraction drive motor, and the deployment and retraction arm is connected to the connecting shaft.

[0010] Due to the adoption of the above technical solution, the synchronous rotation of the connecting shafts on both sides is achieved through the single worm and double turbine structure, ensuring that the antenna unit can be stored synchronously on both sides.

[0011] Furthermore, the support frame is provided with a pitch mechanism, and the pitch mechanism includes a pitch axis that can rotate along a horizontal axis; the deployment mechanism is arranged in the pitch axis and moves with the pitch axis, and the axis of the connecting axis is parallel to the axis of the pitch axis; a connecting port is opened on the side wall of the pitch axis, and the deployment arm is connected to the connecting axis in the pitch axis from the connecting port.

[0012] Due to the adoption of the above technical solution, the design of the pitch mechanism enables the antenna unit to adjust the pitch angle in the horizontal direction, thereby improving the coverage and flexibility of the antenna in complex environments, especially when working in small spaces or complex terrains, the advantages are more obvious.

[0013] Furthermore, the pitch mechanism also includes a pitch worm, a pitch turbine and a pitch drive motor, the pitch turbine is mounted on the pitch shaft, the paired pitch worms are arranged on both sides of the pitch turbine, and the pitch drive motor can synchronously drive the paired pitch worms through a transmission mechanism.

[0014] A general single worm gear has a rotational position locking function. Due to the adoption of the above-mentioned technical solution, the single-turbine double-worm gear structure can provide more effective torque and locking force, thereby increasing the service life of the worm gear, achieving precise control of the pitch axis, and improving the stability and reliability of the antenna when adjusting the pitch angle, effectively solving the operational difficulties of traditional antennas in complex environments.

[0015] Furthermore, the pitch axis can rotate within a range of 0-190 degrees.

[0016] Due to the adoption of the above technical solution, the 0-190 degree rotation design of the pitch axis enables the antenna unit to adapt to different working environments and needs, providing a wider coverage range and enhancing the adaptability and flexibility of the equipment.

[0017] Furthermore, it also includes a rotating base, the support frame is rotatably connected to the rotating base, and the rotating base can drive the support frame to rotate around the vertical axis.

[0018] Due to the adoption of the above technical solution, the design of the rotating base improves the all-round coverage capability of the antenna, and is particularly suitable for use in application scenarios that require multi-directional coverage.

[0019] Furthermore, the rotating base includes a support seat, a rotating drive motor, a driving gear, a driven gear and a rotating shaft. The rotating shaft is rotatably connected to the support seat through a bearing, the driven gear is arranged around the rotating shaft, the driving gear and the driven gear are meshed with each other, and the rotating drive motor is connected to and acts on the driving gear; the rotating drive motor can drive the driving gear to rotate and then drive the driven gear to rotate, the rotating shaft follows the driven gear, and the support frame is connected to the rotating shaft.

[0020] Due to the adoption of the above technical solution, accurate and stable rotation of the support frame is achieved through the engagement of the rotary drive motor and the driving gear with the driven gear, thereby improving the adjustment capability of the antenna in different directions.

[0021] Furthermore, the rotatable angle of the swivel base is 0-360 degrees.

[0022] Due to the adoption of the above technical solution, the 0-360 degree rotation design of the swivel base ensures the flexible adjustment of the antenna unit in all directions, enhances the adaptability and operability of the equipment, and improves the use effect of the antenna in different environments.

[0023] Furthermore, the rotatable angle of the stowage arm is 0-90 degrees.

[0024] Due to the adoption of the above technical solution, the 0-90 degree rotation design of the stowage arm, combined with the 45 degree tilt angle between the display arm and the antenna unit, allows the stowage arm to rotate 90 degrees to switch between the deployed state and the stowed state.

[0025] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: through the design of a 45-degree tilt angle between the deployment arm and the antenna unit, the antenna unit is parallel to the plane of the support frame in the storage state, occupies less space, and is convenient for transportation and storage; in the deployed state, the antenna unit is horizontally located above the support frame, and the paired antenna units are located in the same plane, ensuring the signal reception and transmission performance. The deployment mechanism adopts a single worm and double turbine structure to achieve bilateral synchronous drive, thereby improving the compactness and reliability of the structure. The pitch mechanism design enables the antenna unit to adjust the pitch angle within 0-190 degrees, and the 0-360 degree rotation design of the slewing base enhances the antenna's all-round coverage capability. These designs improve the flexibility and stability of the antenna in complex environments, significantly improve the comprehensive performance of the high-power microwave antenna deployment and collection device, and provide more flexible and reliable support for the application of high-power microwave equipment.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1

[0038] A high-power microwave antenna deployment and reception device, such as Figure 1-8 As shown, it includes an antenna unit 7, an unfolding and retracting mechanism and a support frame, and the antenna unit 7 is rotatably connected to the support frame through the unfolding and retracting mechanism; the antenna unit 7 is a flat plate structure, and the antenna unit 7 is connected to the unfolding and retracting mechanism through an unfolding and retracting arm 12, and the unfolding and retracting mechanism can act on the unfolding and retracting arm 12 and drive the unfolding and retracting arm 12 to rotate around the support frame; an inclined angle of 45 degrees is formed between the unfolding and retracting arm 12 and the antenna unit 7.

[0039] Specifically, the antenna unit 7 can be flexibly rotated through the unfolding and retracting mechanism. The design of the 45-degree inclined angle between the unfolding and retracting arm 12 and the antenna unit 7 enables the antenna unit 7 to be located on one side of the support frame and parallel to the plane where the support frame is located when the antenna unit 7 is in the retracted state, which occupies less space and is convenient for transportation and storage. At the same time, when the antenna unit 7 is in the unfolded state, the antenna unit 7 can be horizontally located above the support frame to ensure the reception and transmission performance of the signal.

[0040] In this embodiment, there are four antenna units 7, and each two antenna units 7 are arranged in a group on both sides of the support frame. The unfolding and retracting mechanism can drive the paired antenna units 7 to switch between the unfolded state and the retracted state. When the antenna units 7 are in the unfolded state, the four antenna units 7 are located in the same plane. When the antenna units 7 are in the retracted state, the paired antenna units 7 are located on both sides of the support frame and are parallel to the plane where the support frame is located. Specifically, the paired antenna units 7 are arranged on both sides of the support frame, which can realize the synchronous storage of both sides, and the structure is more compact.

[0041] The retracting and unfolding mechanism includes a retracting and unfolding worm 8, a retracting and unfolding turbine 9, a retracting and unfolding drive motor 10 and a connecting shaft 11. The paired connecting shafts 11 are arranged relatively on both sides of the retracting and unfolding worm 8. Two pairs of antenna units 7 are arranged axially spaced along the connecting shaft 11. The connecting shaft 11 is provided with a retracting and unfolding turbine 9 meshing with the retracting and unfolding worm 8. The retracting and unfolding drive motor 10 is connected to and acts on the retracting and unfolding worm 8. The retracting and unfolding worm 8 can make the connecting shafts 11 on both sides rotate synchronously through the retracting and unfolding turbine 9 under the action of the retracting and unfolding drive motor 10. The retracting and unfolding arm 12 is connected to the connecting shaft 11. A reducer can be set between the retracting and unfolding drive motor 10 and the retracting and unfolding worm 8 as required. Specifically, through the structure of a single worm and a double turbine, the synchronous rotation of the connecting shafts 11 on both sides is achieved, ensuring that the antenna unit 7 can be retracted synchronously on both sides.

[0042] The support frame is provided with a pitch mechanism, and the pitch mechanism includes a pitch axis 13 that can rotate along a horizontal axis; the deployment mechanism is arranged in the pitch axis 13 and follows the pitch axis 13, and the axis of the connecting axis 11 is parallel to the axis of the pitch axis 13; a connecting port is provided on the side wall of the pitch axis 13, and the deployment arm 12 is connected to the connecting axis 11 in the pitch axis 13 from the connecting port. A reducer can be arranged between the pitch drive motor 16 and the pitch worm 14 as required. Specifically, the design of the pitch mechanism enables the antenna unit 7 to adjust the pitch angle in the horizontal direction, thereby improving the coverage and use flexibility of the antenna in complex environments, especially when working in narrow spaces or complex terrains, the advantages are more obvious.

[0043] The pitch mechanism further includes a pitch worm 14, a pitch turbine 15 and a pitch drive motor 16. The pitch turbine 15 is mounted on the pitch shaft 13, and the paired pitch worms 14 are arranged on both sides of the pitch turbine 15. The pitch drive motor 16 can synchronously drive the paired pitch worms 14 through a transmission mechanism 17. Specifically, a single worm generally has a rotation position locking function. The structure of a single turbine and double worms can provide more effective torque and locking force, increase the service life of the turbine worm, achieve precise control of the pitch shaft 13, improve the stability and reliability of the antenna when adjusting the pitch angle, and effectively solve the operation problem of traditional antennas in complex environments.

[0044] The rotatable angle of the pitch axis 13 is 0-190 degrees. Specifically, the 0-190 degree rotation design of the pitch axis 13 enables the antenna unit 7 to adapt to different working environments and requirements, provide a wider coverage range, and enhance the adaptability and flexibility of the device.

[0045] The antenna also includes a swivel base, the support frame is rotatably connected to the swivel base, and the swivel base can drive the support frame to rotate around a vertical axis. Specifically, the design of the swivel base improves the omnidirectional coverage capability of the antenna, and is particularly suitable for use in application scenarios that require multi-directional coverage.

[0046] The swivel base includes a support base 1, a swivel drive motor 4, a driving gear 5, a driven gear 6 and a swivel shaft 3. The swivel shaft 3 is rotatably connected to the support base 1 through a bearing. The driven gear 6 is arranged around the swivel shaft 3. The driving gear 5 and the driven gear 6 are meshed with each other. The swivel drive motor 4 is connected to and acts on the driving gear 5. The swivel drive motor 4 can drive the driving gear 5 to rotate and then drive the driven gear 6 to rotate. The swivel shaft 3 follows the driven gear 6, and the support frame is connected to the swivel shaft 3. A reducer can be set between the swivel drive motor 4 and the driving gear 5 as required. Specifically, through the meshing of the swivel drive motor 4 and the driving gear 5 with the driven gear 6, the precise and stable rotation of the support frame is achieved, and the adjustment ability of the antenna in different directions is improved.

[0047] The rotatable angle of the swivel base is 0-360 degrees. Specifically, the 0-360 degree rotation design of the swivel base ensures the flexible adjustment of the antenna unit 7 in all directions, enhances the adaptability and operability of the device, and improves the use effect of the antenna in different environments.

[0048] The rotatable angle of the stowable arm 12 is 0-90 degrees. Specifically, the 0-90 degree rotation design of the stowable arm 12, combined with the 45 degree tilt angle between the stowable arm 12 and the antenna unit 7, enables the stowable arm 12 to rotate 90 degrees to switch between the deployed state and the stowed state.

[0049] When the high-power microwave antenna deployment and retraction device is in the initial state, the antenna unit 7 is vertically stored on both sides of the support base 1. When the high-power microwave antenna deployment and retraction device is used, the deployment and retraction worm 8 is first driven to rotate by the deployment and retraction drive motor 10, and the deployment and retraction worm 8 causes the connecting shaft 11 to rotate synchronously through the deployment and retraction turbine 9, thereby driving the deployment and retraction arm 12 to rotate within the range of 0-90 degrees. When the deployment and retraction arm 12 rotates 90 degrees, the antenna unit 7 switches from the storage state to the deployment state. At this time, the antenna unit 7 is horizontally located above the support frame, and the paired antenna units 7 are located in the same plane to ensure the signal reception and transmission performance. If the pitch angle of the antenna needs to be adjusted, the pitch drive motor 16 can be used to drive the pitch worm 14 to rotate, and the pitch worm 14 can rotate the pitch axis 13 through the pitch turbine 15 to adjust the pitch angle of the antenna unit 7, ranging from 0 to 190 degrees. Finally, if the direction of the antenna needs to be adjusted, the driving gear 5 can be driven to rotate by the rotary drive motor 4, and the driving gear 5 rotates the rotating shaft 3 through the driven gear 6, and the support frame rotates around the vertical axis with the rotating shaft 3, ranging from 0 to 360 degrees, to achieve full coverage of the antenna. During transportation and storage, the reverse operation is performed to fold the antenna unit 7 and store it on one side of the support frame, which takes up less space.
