Description

Technical Field

[0001] The invention relates to the field of high-power antennas, and in particular to an automatic air pressure balancing device for a high-power microwave antenna. Background Art

[0002] High-power microwave technology has extensive and important applications in many fields such as radar, communication, electronic countermeasures, high-energy physics, etc. As the core component of high-power microwave systems, the performance of high-power microwave antennas is directly related to the working effect and stability of the entire system.

[0003] In the actual operation of high-power microwave antennas, there are many complex environmental factors and technical challenges, among which the impact of air pressure changes on antenna performance is particularly significant. When traditional high-power microwave antennas are working, the ambient air pressure in which they are located may change due to a variety of reasons. For example, at different altitudes, there will be obvious differences in atmospheric pressure; the heat generated during the operation of the antenna will also cause the surrounding gas to expand or contract, causing fluctuations in local air pressure. In addition, when high-power microwave antennas are used on mobile platforms such as aerospace and vehicles, the movement of the platform and environmental changes will also make the air pressure around the antenna unstable.

[0004] Changes in air pressure can cause a series of problems for high-power microwave antennas. On the one hand, fluctuations in air pressure may affect the electric field distribution inside the antenna, resulting in increased energy loss during microwave transmission and reduced antenna radiation efficiency. When the air pressure is too low, it may cause gas ionization and produce a discharge effect, which will not only interfere with the normal operation of the antenna, but in severe cases may even damage the internal structure and electronic components of the antenna. On the other hand, changes in air pressure may also cause deformation of the antenna's mechanical structure, affecting the antenna's pointing accuracy and beam shape, thereby reducing the antenna's ability to detect and track targets.

[0005] In order to solve the impact of air pressure changes on the performance of high-power microwave antennas, some air pressure balance measures have been proposed in the prior art. Some solutions use a simple sealing structure to try to isolate the antenna from the external environment to reduce the impact of air pressure changes. However, this method can only alleviate the problem of air pressure fluctuations to a certain extent, and cannot achieve automatic adjustment and precise balance of air pressure. When the ambient air pressure changes greatly, the air pressure inside the sealed structure will still produce a large pressure difference with the outside world, thereby affecting the performance of the antenna. There are also some solutions that manually check and adjust the air pressure inside the antenna on a regular basis, but this method is not only inefficient, but also difficult to ensure the timeliness and accuracy of air pressure adjustment, and cannot meet the continuous and stable operation requirements of high-power microwave antennas in complex and changing environments.

[0006] In the application scenario of high-power microwave antenna arrays, the problem is even more complicated. Since multiple horn antennas are distributed in an array, the local environment of each antenna may be different, and the air pressure changes may also be different. If the air pressure balance control of each antenna cannot be performed independently and accurately, the overall performance of the antenna array will be reduced, affecting the synthesis and radiation effect of the microwave.

[0007] In summary, the existing air pressure balancing technology has obvious limitations in the application of high-power microwave antennas. There is an urgent need for a high-power microwave antenna air pressure automatic balancing device that can automatically and accurately balance the air pressure, adapt to complex environmental changes, and is suitable for antenna arrays, so as to improve the performance and reliability of high-power microwave antennas and meet the growing practical application needs. Summary of the invention

[0008] The purpose of the present invention is: to address the above-mentioned problems, the present invention provides a high-power microwave antenna air pressure automatic balancing device, which can effectively solve the above-mentioned problems in the prior art and realize automatic balancing and stable control of the air pressure of the high-power microwave antenna by filling insulating gas in the antenna cover and arranging components such as inflation pipes, inflation valves, pressure gauges and balancing airbags.

[0009] The technical solution adopted by the present invention is as follows:

[0010] A high-power microwave antenna air pressure automatic balancing device comprises a plurality of horn antennas. The balancing device is covered on the outside of the antennas, and insulating gas is filled between the balancing device and the antennas.

[0011] Due to the adoption of the above technical scheme, the balancing device cover is arranged on the outside of the antenna and filled with insulating gas, which can create a stable working environment for the horn antenna. The insulating gas can effectively prevent the antenna from discharging when working with high-power microwaves, thereby improving the safety and stability of the antenna and ensuring the normal emission and transmission of high-power microwaves.

[0012] Furthermore, the plurality of horn antennas are distributed in an array.

[0013] Due to the adoption of the above technical solution, the array distribution of several horn antennas can enhance the radiation performance and directivity of the antenna. Through reasonable array layout, high-power microwaves can be emitted more concentratedly and directionally, improving the utilization efficiency of microwave energy and meeting the requirements for microwave coverage and intensity in specific scenarios.

[0014] Furthermore, the balancing device includes a plurality of radomes, the number of which corresponds to the number of horn antennas, and the radomes are filled with insulating gas.

[0015] Due to the adoption of the above technical solution, each horn antenna corresponds to a radome filled with insulating gas, which can independently protect and balance the air pressure of a single horn antenna. This can avoid mutual interference between the horn antennas, and at the same time, the insulating gas in each radome can specifically protect the corresponding antenna, thereby improving the reliability and stability of the entire antenna system.

[0016] Furthermore, the plurality of horn antennas are all arranged on the surface of the antenna base plate, the radome is connected to the antenna base plate, the plurality of radomes are distributed corresponding to the horn antenna array, and each horn antenna and the radome are distributed independently.

[0017] Due to the adoption of the above technical solution, the horn antenna is set on the surface of the antenna bottom plate and is independently distributed with the radome, which is convenient for the installation, debugging and maintenance of the antenna. At the same time, the radome is distributed corresponding to the horn antenna array, making the entire antenna system structure more compact and regular, which is conducive to optimizing the spatial layout and improving the overall performance and stability of the system.

[0018] Furthermore, several of the antenna covers are provided with an inflation pipe, and the inflation pipes of the various antenna covers are connected and converged under the antenna base plate, and the antenna base plate is provided with an inflation valve that cooperates with the inflation pipe.

[0019] Due to the adoption of the above technical solution, the air pressure in each radome can be easily adjusted and controlled by setting the inflation pipe and inflation valve. The inflation pipes of each radome are connected and connected to the bottom of the antenna base plate, which is convenient for centralized management and operation, improves the efficiency and convenience of air pressure regulation, and ensures that the air pressure in each radome can quickly reach a balanced state.

[0020] Furthermore, the inflation valve is externally connected to a pressure gauge and a balancing airbag, and the balancing airbag is in communication with an inflation pipe.

[0021] Due to the adoption of the above technical solution, the pressure gauge can monitor the air pressure in the radome in real time, and the operator can timely understand the air pressure status according to the reading of the pressure gauge and make corresponding adjustments. The balancing airbag is connected to the inflation pipe. When the air pressure changes, the balancing airbag can play a role in buffering and regulating the air pressure, so that the air pressure in the radome is kept within a stable range, further improving the reliability and stability of the air pressure automatic balancing device.

[0022] Furthermore, a carbon fiber frame is provided below the antenna base plate, and the inflation pipes are distributed in the carbon fiber frame.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] The invention discloses an automatic air pressure balancing device for high-power microwave antennas. Each horn antenna corresponds to an radome filled with insulating gas, which can independently protect and balance the air pressure of a single horn antenna. In this way, mutual interference between the horn antennas can be avoided. At the same time, the insulating gas in each radome can protect the corresponding antenna in a targeted manner, thereby improving the reliability and stability of the entire antenna system. The air pressure in each radome can be conveniently regulated and controlled by setting the inflation pipe and the inflation valve. The inflation pipes of each radome are connected and converged to the bottom of the antenna base plate, which is convenient for centralized management and operation, improves the efficiency and convenience of air pressure regulation, and ensures that the air pressure in each radome can quickly reach a balanced state.

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] 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.

[0031] Example 1

[0032] The high-power microwave antenna air pressure automatic balancing device provided in this embodiment includes a plurality of horn antennas, which are key components for transmitting high-power microwaves. The balancing device is integrally covered on the outside of the antenna to form a relatively closed space. An insulating gas, such as sulfur hexafluoride SF6, is filled between the balancing device and the antenna. It has good insulation performance and arc extinguishing ability, can effectively prevent the antenna from discharging when the high-power microwave is working, and improve the safety and stability of the antenna.

[0033] like Figure 1 and Figure 2 As shown, a plurality of horn antennas 1 are distributed in a regular array on the antenna base plate 4. This distribution can enhance the radiation performance and directivity of the antenna, so that high-power microwaves can be emitted in a more concentrated and directed manner, thereby improving the utilization efficiency of microwave energy.

[0034] The balancing device is composed of a plurality of radomes 2, and the number of radomes 2 corresponds to the number of horn antennas 1. Each radome 2 is filled with insulating gas, so that a single horn antenna can be independently protected and the air pressure balance can be adjusted to avoid mutual interference between the horn antennas.

[0035] All horn antennas 1 are mounted on the surface of antenna base plate 4, and antenna covers 2 are connected to antenna base plate 4. Several antenna covers 2 are arranged according to the array distribution of horn antennas 1, and each horn antenna 1 is independent of the corresponding antenna cover 2, which is convenient for installation, debugging and maintenance of the antenna.

[0036] like Figure 3 As shown, an air-filling pipe 6 is provided in each antenna cover 2, and these air-filling pipes 6 are used to inflate or deflate the antenna cover 2 to adjust the air pressure. The air-filling pipes 6 of each antenna cover 2 are connected and converged under the antenna bottom plate 4. The antenna bottom plate 4 is provided with an air-filling valve that cooperates with the air-filling pipe 6. The air inlet and outlet of the air can be conveniently controlled by the air-filling valve, and the air-filling valve is provided on the air-filling port 5.

[0037] The inflation valve is externally connected to a pressure gauge and a balancing airbag 7. The pressure gauge is used to monitor the air pressure in the radome in real time. The operator can timely understand the air pressure status according to the reading of the pressure gauge. The balancing airbag 7 is connected to the inflation pipe. When the air pressure changes, the balancing airbag 7 can play a role in buffering and regulating the air pressure, so that the air pressure in the radome 2 is kept within a stable range.

[0038] The working process of this embodiment:

[0039] When the device starts working, high-power microwaves are emitted through the horn antenna. During operation, various factors (such as ambient temperature changes, microwave energy loss, etc.) may cause changes in the air pressure inside the antenna cover.

[0040] The pressure gauge will monitor the air pressure changes in real time and feed the data back to the operator. If the air pressure is lower than the set value, the operator can open the inflation valve and use the inflation pipe to fill the antenna cover with insulating gas. At the same time, the balance airbag will expand or contract accordingly according to the air pressure changes, playing a buffering role and gradually restoring the air pressure to the normal range.

[0041] If the air pressure is higher than the set value, the operator can discharge some of the gas through the inflation valve. Similarly, the balance airbag will also participate in the air pressure adjustment process to ensure stable air pressure.

[0042] Example 2

[0043] This embodiment provides an intelligent high-power microwave antenna air pressure automatic balancing device, the device comprising:

[0044] Similar to the first embodiment, it comprises a plurality of horn antennas distributed in an array, the balancing device cover is arranged outside the antenna, and the space between the balancing device and the antenna and inside each antenna cover are filled with insulating gas (such as nitrogen).

[0045] The difference is that this device introduces an intelligent control system. A high-precision air pressure sensor is installed in each radome to monitor air pressure changes in real time and accurately. At the same time, the inflation valve uses an electric valve, which is controlled by an intelligent control system.

[0046] The intelligent control system may be a system based on a single chip microcomputer or an industrial computer, which receives data from the air pressure sensor and analyzes and processes the data according to a preset air pressure balance algorithm.

[0047] In addition, it is equipped with a wireless communication module. The intelligent control system can upload air pressure data and device working status to the remote monitoring center through wireless communication, making it convenient for operators to conduct remote monitoring and management.

[0048] The working process of this embodiment is as follows:

[0049] The air pressure sensor continuously monitors the air pressure inside the radome and transmits the data to the intelligent control system in real time.

[0050] The intelligent control system compares and analyzes the actual air pressure value with the preset standard air pressure value. If there is a deviation in the air pressure, the intelligent control system will calculate the required adjustment amount according to the preset algorithm and send a control instruction to the electric inflation valve.

[0051] The electric inflation valve automatically opens or closes according to the command, realizing automatic adjustment of the air pressure in the radome. At the same time, the balance airbag still plays the role of buffering the air pressure change.

[0052] The remote monitoring center can receive data uploaded by the device in real time. Operators can set parameters and diagnose faults on the device in the remote monitoring center, which improves the management efficiency and intelligence level of the device.

[0053] Example 3

[0054] This embodiment provides a large array high-power microwave antenna air pressure automatic balancing device, the device comprising:

[0055] This embodiment is directed to a large high-power microwave antenna array, including a large number of horn antennas distributed in a large-scale array. The balancing device is also composed of a plurality of radomes, each radome corresponds to a horn antenna, and the radome is filled with insulating gas (such as dry air).

[0056] In order to meet the air pressure balance requirements of large arrays, a multi-stage air filling pipe system is adopted. The air filling pipes in each radome are first connected to the primary manifold, which is then connected to the secondary manifold, and finally all the secondary manifolds are connected to the main air filling pipe under the antenna base.

[0057] A plurality of inflation valves are arranged on the antenna base plate, and each inflation valve corresponds to a group of radomes (for example, radomes within a region), so that zoning control can be realized and the flexibility and efficiency of air pressure regulation can be improved.

[0058] Each inflation valve is connected to an independent pressure gauge and a balance airbag to monitor and adjust the air pressure of the radome in the area in real time. At the same time, it is also equipped with a central air pressure monitoring system, which can summarize the data of each pressure gauge and fully grasp the air pressure distribution of the entire device.

[0059] The working process of this embodiment is as follows:

[0060] During the operation of the device, the central air pressure monitoring system collects and analyzes the air pressure data of each area in real time.

[0061] If the air pressure in a certain area is abnormal, the operator can adjust the air pressure by controlling the corresponding inflation valve in that area. For example, if the air pressure in a certain area is too low, open the inflation valve in that area and fill the radome in that area with insulating gas through the multi-stage inflation pipeline system.

[0062] The balance airbags in each area will be adjusted accordingly according to the changes in air pressure to ensure stable air pressure in that area. The central air pressure monitoring system will continuously monitor the air pressure of the entire device and coordinate the control of the inflation valves in different areas as needed to achieve automatic air pressure balance for the entire large antenna array.

[0063] Example 4

[0064] This embodiment provides a high-temperature resistant high-power microwave antenna air pressure automatic balancing device, the device comprising:

[0065] It also has multiple horn antennas distributed in an array. The balancing device cover is arranged on the outside of the antenna. The antenna cover is filled with high-temperature resistant insulating gas, such as helium. Helium has good thermal stability and insulating properties, and can maintain stable performance in high temperature environment.

[0066] The antenna cover is made of high-temperature resistant materials, such as ceramic fiber composite materials, which have excellent high-temperature resistance and mechanical strength and can withstand the high temperatures generated when high-power microwaves are working.

[0067] The inflation pipe and inflation valve are also made of high temperature resistant materials, such as stainless steel alloy, to ensure that the air pressure regulation function will not be affected by thermal expansion or material aging in a high temperature environment.

[0068] The pressure gauge and balance airbag are specially designed to work normally in high temperature environment. The pressure gauge uses high temperature resistant sensor and meter head, and the balance airbag is made of high temperature resistant rubber material.

[0069] The working process of this embodiment is as follows:

[0070] When a high-power microwave antenna is working, a lot of heat will be generated, causing the temperature inside the device to rise. Since the helium filled has good thermal stability, it can maintain stable gas pressure and insulation performance at high temperatures.

[0071] High temperature resistant antenna cover, inflation pipe, inflation valve, pressure gauge, balance airbag and other components can work normally in high temperature environment, ensuring the reliability of the air pressure regulation system.

[0072] When the air pressure changes, the inflation valve is operated and helium is filled into or discharged from the antenna cover through the inflation pipe. At the same time, the balance airbag acts as a buffer to keep the air pressure within a stable range, ensuring the normal operation of the high-power microwave antenna in a high-temperature environment.
