Description

Technical Field

[0001] The present invention relates to ship equipment technology, and in particular to an air-cooled and heat-dissipating rotatable outboard jamming device. Background Art

[0002] To truly test the maritime combat performance of active equipment, it is necessary to construct a maritime confrontation scenario for the equipment under test. By providing realistic targets, the equipment under test can be tested to verify its true performance, thereby providing research directions for equipment performance improvement. As a general test equipment, the outboard jammer can generally be remotely controlled, capable of performing signal detection and parameter measurement, with flexible binding and adjustment of jamming patterns and multi-technical jamming capabilities. Based on the requirements of missile flight test missions, it can be installed on unmanned remote-controlled mobile platforms to create terminal active outboard jamming scenarios for anti-ship missile live-fire exercises.

[0003] Currently, outboard jammers are typically fixed-mounted. While maintaining functionality, these devices are bulky and heavy. Adjusting the jammer's target azimuth requires the installation of a high-load-bearing, anti-tilt turntable. This creates even higher requirements for the target-carrying platform to ensure the safety of the outboard jammer, especially in harsh sea conditions. Summary of the Invention

[0004] The object of the present invention is to provide an air-cooled and heat-dissipating rotatable outboard jamming device.

[0005] The technical solution for achieving the purpose of the present invention is: an air-cooled and heat-dissipating rotatable outboard jamming device, comprising an outboard chassis, a radome, an azimuth rotation assembly, an interference source assembly, a millimeter-wave transmitter assembly, a centimeter-wave transmitter assembly, a main control assembly, a servo control assembly, a secondary power supply, a waveguide assembly, and a fan;

[0006] The outboard chassis adopts a splicing structure; the interference source combination, millimeter wave transmitter combination, centimeter wave transmitter combination, main control combination, servo control combination, and secondary power supply are respectively installed on the six surfaces of the outboard chassis; a waveguide rotation joint is set at the rotation center of the azimuth rotation combination, the antenna combination is fixed on the rotating main shaft, and the motor directly drives the power gear to realize 360° azimuth rotation of the antenna combination; ventilation holes are set at the diagonal positions of the bottom of the outboard chassis, and a fan is installed at the ventilation hole at one end, which cooperates with the internal fan of the interference source combination to realize effective flow of air inside the entire chassis and external air.

[0007] Furthermore, stop structures are provided at the joints of the outboard engine case.

[0008] Furthermore, the bottom of the outboard chassis is fixed with an adapter plate, which adopts a hollow structure design.

[0009] Furthermore, three maintenance covers are provided on the outboard chassis, and the millimeter wave transmitter assembly, centimeter wave transmitter assembly, and secondary power supply are installed on the maintenance covers with heat spreaders.

[0010] Furthermore, the maintenance cover adopts a heat sink design.

[0011] Furthermore, thermal grease is applied to the mounting surfaces of the millimeter wave transmitter assembly, the centimeter wave transmitter assembly, and the bottom of the secondary power supply.

[0012] Furthermore, fins are left on the outside of the maintenance cover, and the direction of the fin guide grooves on the outer surface is consistent with the movement direction of the device.

[0013] Furthermore, the azimuth rotation combination adopts a dual limit design of mechanical and electrical limits. The annular follower disturber rod is installed on the rotating main shaft, and the annular brake disturber rod is installed on the outer ring structure of the deep groove ball bearing. The main shaft drives the annular follower disturber rod to rotate to the electrical limit angle. In the event of failure of the electrical limit mechanism, it continues to rotate until the fork arm structure on the annular follower disturber rod contacts the stop column on the annular brake disturber rod. The external limit stop column is installed on the base of the azimuth rotation combination. When the annular brake disturber rod contacts the external limit stop column and there is no movement, the annular follower disturber rod also stops moving. At this time, the azimuth rotation realizes mechanical limit.

[0014] Compared with the existing technology, the present invention has the following significant advantages:

[0015] (1) Low manufacturing difficulty and high space utilization: The outboard chassis is rationally divided into multiple structural units by adopting the method of sub-type design, which reduces the overall manufacturing difficulty and processing cost; the electronic equipment inside the outboard device is installed on the six sides of the outboard chassis respectively, which effectively utilizes the scattered areas inside the chassis and has a high overall space utilization rate.

[0016] (2) Flexible installation and maintenance: The entire outboard jammer is small in size and light in weight. The bottom fixed adapter plate adopts a ring-shaped hollow structure. The antenna array orientation can be adjusted according to actual conditions during installation, and the installation plan is flexible and changeable. Maintenance covers are designed around the outside of the outboard chassis. After removal, the internal electronic modules can be directly maintained, which is convenient for maintenance.

[0017] (3) Safe and reliable azimuth rotation: The interference azimuth angle of the outboard device is achieved by directly rotating the antenna combination, without the need for the entire outboard device to be rotated in azimuth. The load of the azimuth turntable is greatly reduced and the volume is greatly reduced, ensuring that the entire outboard device will not fall off as a result of the breakage of the turntable main shaft under severe sea conditions. At the same time, the azimuth rotation combination adopts a dual limit design of mechanical and electrical limits, and a waveguide rotation joint is designed at the main shaft rotation center. The antenna combination is fixed on the rotating main shaft, and the motor directly drives the power gear to achieve 360° rotation of the antenna combination. The azimuth rotation is safe and reliable.

[0018] (4) The heat dissipation form is simple, efficient, and has strong environmental adaptability: the bottom mounting surfaces of all heat-generating components are coated with thermal grease, which effectively reduces the contact thermal resistance and improves the heat dissipation efficiency; the high heat consumption module is directly installed on the finned side maintenance cover, and the maintenance cover adopts a heat spreader design inside to significantly reduce the surface temperature gradient and avoid excessive temperature of the module; the direction of the fin guide groove of the maintenance cover for installing the millimeter wave and centimeter wave transmitter combination is consistent with the direction of platform movement, which effectively enhances the heat dissipation effect of the heat dissipation fin; the bottom of the outboard chassis is designed with a diagonal vent, and the air heat exchange between the inside and outside of the chassis is achieved through the fan, which solves the heat dissipation requirements of the internal non-wall-mounted modules and further enhances the heat dissipation effect of high heat consumption modules such as the transmitter. Under the conditions of the external wind speed not less than 1.5m / s and the sea surface environment not higher than 40℃, the operating temperature of the outboard jammer can be controlled within a reliable range, and the environment is highly adaptable.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] like Figure 1 、 Figure 2 as well as Figure 3 As shown, an air-cooled and heat-dissipating rotatable outboard jamming device includes an outboard chassis 1, a radome 2, an azimuth rotation assembly 3, an interference source assembly 4, a millimeter wave transmitter assembly 5, a centimeter wave transmitter assembly 6, a main control assembly 7, a servo control assembly 8, a secondary power supply 9, a waveguide assembly 10 and a fan 11.

[0029] In a further embodiment, Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, the outboard chassis adopts a splicing structure, and the joints are all designed with stoppers. The bottom fixed adapter plate adopts a hollow structure design. By means of parting design, the outboard chassis 1 is rationally split into multiple structural units. The entire outboard chassis 1 is formed by splicing. Each structural component is designed to reduce weight, eliminating the need for integral casting, effectively reducing the manufacturing difficulty, processing cost and overall weight of the chassis. The six surface structural components of the outboard chassis 1 are all designed with stoppers, which effectively enhances the assembly strength of the structural components. During assembly, silicone rubber is evenly applied to the stoppers, which is conducive to improving the rainproof ability of the outer surface of the outboard chassis 1. The bottom fixed adapter plate adopts a hollow structure design, which greatly reduces the weight of the structural components while ensuring strength. The fixed adapter plate and the platform are rigidly connected, which is highly safe.

[0030] In a further embodiment, Figure 1、 Figure 2 as well as Figure 3 As shown. The interference source combination, millimeter wave transmitter combination, centimeter wave transmitter combination, main control combination, servo control combination, and secondary power supply are respectively installed on the six sides of the outboard chassis. The interference source combination 4, millimeter wave transmitter combination 5, centimeter wave transmitter combination 6, main control combination 7, servo control combination 8, and secondary power supply 9 are respectively installed on the six sides of the outboard chassis 1, effectively utilizing the scattered areas inside the chassis and achieving high overall space utilization. In a further embodiment, maintenance covers are designed around the outboard chassis 1, and a sealing design is performed between the cover and the installation surface to ensure sealing performance; after the maintenance covers around the outboard chassis 1 are removed, the internal electronic modules can be directly maintained, which is convenient for maintenance. In a further embodiment, the maintenance cover adopts a heat sink design, and fins are left on the outside of the maintenance cover. High-heat-consumption combinations such as millimeter-wave transmitter combination 5, centimeter-wave transmitter combination 6, and secondary power supply 7 are installed on a maintenance cover with a heat spreader design, which can significantly reduce the temperature gradient of the heat dissipation surface. When installing the modules, all mounting surfaces are coated with thermal grease to effectively reduce contact thermal resistance and improve heat dissipation efficiency. The direction of the fin guide grooves on the maintenance cover for installing millimeter-wave transmitter combination 5 and centimeter-wave transmitter combination 6 is consistent with the direction of platform movement, effectively enhancing the heat dissipation effect of the heat dissipation fins.

[0031] In a further embodiment, Figure 2 、 Figure 3 、 Figure 5 as well as Figure 6As shown, the azimuth rotation assembly's main shaft rotation center is designed with a waveguide rotary joint. The antenna assembly is fixed to the rotating main shaft, and a motor directly drives a power gear to achieve 360° azimuth rotation of the antenna assembly. The main shaft rotation center is designed with a waveguide rotary joint 3-1, which enables signal transmission between the millimeter-wave transmitting antenna and the millimeter-wave traveling wave tube 5-1. Signal transmission between the centimeter-wave transmitting antenna, the centimeter-wave receiving antenna, and the millimeter-wave receiving antenna all utilizes cables, whose rotation axis is near the main shaft axis, minimizing the impact of rotation on the cables. Antenna assembly 3-2 is entirely fixed to the rotating main shaft, and a motor directly drives a power gear to achieve 360° azimuth rotation of antenna assembly 3-2. This eliminates the need for azimuth rotation of the entire outboard device, significantly reducing the load on the azimuth turntable and its size, and ensuring a safe and reliable rotation mechanism. In addition, the azimuth rotation combination 3 adopts a dual limit design of mechanical and electrical limits. The annular follower disturber 3-3 is installed on the rotating main shaft, and the annular brake disturber 3-4 is installed on the outer ring structure of the deep groove ball bearing. The main shaft drives the annular follower disturber 3-3 to rotate to the electrical limit angle. In the event of failure of the electrical limit mechanism, it continues to rotate until the fork arm structure on the annular follower disturber 3-3 contacts the stop column on the annular brake disturber 3-4. The external limit stop column 3-5 is installed on the base of the azimuth rotation combination. When the annular brake disturber 3-4 contacts the external limit stop column 3-5 and there is no movement, the annular follower disturber 3-3 also stops moving. At this time, the azimuth rotation realizes mechanical limit, wherein the angle formed by the two fork arms of the annular follower disturber 3-3 relative to the central axis of the annular brake disturber 3-4 is β, and the angle of the maximum outer shape of the external limit stop column 3-5 relative to the center of the rotation axis is γ. It is necessary to ensure β>γ during design.

[0032] In a further embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, the outboard chassis is designed with vents at the diagonal positions on the bottom, and a fan is installed at the vent at one end, which cooperates with the internal fan of the interference source combination to achieve effective flow of air inside the entire chassis and the outside air. The bottom of the outboard chassis 1 is designed as a non-sealed structure, with two vents reserved at the diagonal positions. An axial flow fan 11 that blows air to the outside is installed at one vent, which cooperates with the fan inside the interference source combination 4 that blows air upward to achieve effective flow of air inside the entire chassis and the outside air, solving the heat dissipation needs of internal non-wall-mounted modules and further enhancing the heat dissipation effect of high-heat consumption modules such as transmitters. The heat dissipation adopts a direct forced air cooling method, which makes full use of the relative airflow during platform movement and the bottom vents to achieve the heat dissipation design of the module. The heat dissipation form is simple and efficient.

[0033] In a further embodiment, the millimeter wave transmitter combination includes a millimeter wave traveling wave tube 5-1, a millimeter wave main control board 5-2, a millimeter wave high-voltage power supply 5-3, and a millimeter wave frequency conversion module 5-4; the centimeter wave transmitter combination includes a centimeter wave traveling wave tube 6-1, a centimeter wave main control board 6-2, a centimeter wave high-voltage power supply 6-3, and a centimeter wave frequency conversion module 6-4; the main control combination 7 includes a main control storage industrial computer 7-1, a network switch 7-2, and an interface control board 7-3; the servo control combination 8 includes a servo control board 8-1, a servo driver 8-2, and an attitude measurement receiver 8-3.

[0034] In summary, the present invention can adjust the azimuth within a range of 360° according to the target azimuth. The device is small in size, light in weight, flexible in loading scheme, and safe and reliable in azimuth rotation. It has low requirements on the weight and space of the platform, and makes full use of the ambient wind during the platform's navigation to achieve heat dissipation of the interference device, and has strong environmental adaptability.

[0035] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
