Description

Technical Field

[0001] This invention belongs to the field of phased array navigation radar technology, specifically a modular shipborne phased array navigation radar. Background Technology

[0002] Modular shipborne phased array navigation radar is a navigation radar system installed on ships and using phased array antennas to achieve electronic beam scanning. Its core feature is that through modular architecture design, core functional units such as antenna array, transceiver components, and signal processing are broken down into standardized "building block" modules, which can be flexibly combined and expanded according to the mission requirements of ships of different tonnages.

[0003] In existing technologies, when phased array navigation radars operate in low-temperature rain and snow weather, ice and snow adhere to the antenna array surface. As a medium, ice and snow absorb and reflect electromagnetic waves, leading to a decrease in signal strength and even beam distortion, ultimately affecting the radar's detection range and accuracy. Furthermore, under repeated freeze-thaw cycles, meltwater may seep into the array surface through gaps, increasing the risk of corrosion and short circuits in antenna elements or feeder networks, thus shortening the equipment's lifespan.

[0011] Preferably, one end of the slide rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to one side of the inner wall of the reciprocating rod.

[0012] Preferably, it includes a size-adaptive dewatering assembly; The size-adaptive dewatering assembly is slidably disposed on the inner and outer connecting rods on both sides of the outer wall of the adjusting cylinder.

[0015] The beneficial effects of this invention are as follows: 1. The modular shipborne phased array navigation radar of this invention utilizes an area-adaptive antenna array de-icing assembly to achieve de-icing of the antenna array surface. This avoids the signal strength reduction and even beam distortion caused by ice and snow adhering to the antenna array surface, ultimately affecting the radar's detection range and accuracy. Furthermore, it prevents excessive meltwater residue on the antenna array surface, avoiding seepage into the antenna array through gaps, which could increase the risk of corrosion and short circuits in antenna elements or feeder networks, thus extending equipment lifespan. In addition, compared to heating the entire antenna array for de-icing and snow removal, this solution uses a dynamically adjustable enclosure structure to contain the icing area. While ensuring the icing area is contained, the overall size of the enclosure is minimized, and the insulation cloth provides insulation, concentrating heat in the icing area. This saves resources, allows for rapid melting of ice and snow, and facilitates the extraction of meltwater.

[0016] 2. The modular shipborne phased array navigation radar of the present invention utilizes a melting auxiliary component to cause a striking ball to impact the ice layer on the surface of the antenna array during the heating and melting process of the ice layer. This causes the ice layer to crack under the action of the striking ball, allowing heat to be transferred to the interior of the ice layer more quickly through the cracks, thereby accelerating the melting speed of the ice layer and improving the de-icing efficiency.

[0017] 3. The modular shipborne phased array navigation radar of this invention utilizes a size-adaptive water-squeezing assembly. During the meltwater extraction process, the water in the insulation cloth is squeezed out by the action of inner rod one, inner rod two, outer rod one, and outer rod two. This avoids the problem of meltwater being absorbed by the insulation cloth, which can lead to fiber aging, hardening, and mold growth. This helps extend the service life of the insulation cloth and reduces replacement frequency and maintenance costs. Furthermore, it also avoids the secondary freezing of meltwater in the insulation cloth at low temperatures, which could cause the insulation cloth to freeze and stick to the antenna array surface, resulting in scratch damage to the antenna array surface when the enclosure structure is retracted or moved.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-13 The present invention provides a technical solution: a modular shipborne phased array navigation radar, including a phased array navigation radar body 4 and a housing 1. The phased array navigation radar body 4 is fixedly installed on one side of the upper end of the housing 1, and includes an area-adaptive antenna array de-icing assembly. The area-adaptive antenna array de-icing assembly includes a mounting plate 5 and a thermally stable microstrip patch antenna sensor array deployed on the surface of the antenna array. The sensor array consists of multiple microstrip patch antenna sensors arranged at predetermined intervals. Each sensor independently monitors the change in dielectric constant of its corresponding area. When ice forms in the area, the resonant frequency of the sensor shifts. By detecting the frequency shift of each sensor, the location and area of ​​the ice formation can be determined. A bidirectional screw guide module 1 9 is provided on one side of the mounting plate 5. The bidirectional screw guide module 1 9 has two moving ends that move in opposite directions, and a slide plate 14 is fixedly connected to the two moving ends. A bidirectional screw guide module 27 is provided on one side of the lower end face of the slide plate 14. The bidirectional screw guide module 27 has two moving ends that move in opposite directions, and an adjusting cylinder 28 is fixedly connected to each of the two moving ends. A roller 25 is rotatably provided at one end of the inner cavity of the adjusting cylinder 28. An insulation cloth 15 is wound on the roller 25. The insulation cloth 15 slides through one side of the adjusting cylinder 28, and the end of the insulation cloth 15 is fixedly connected to the outer wall of the adjusting cylinder 28 on the other side. The four insulation cloths 15 cooperate with each other to form a rectangular enclosure that matches the area of ​​the icing area. An electric heating coil 39 for heating the inside of the enclosure is provided on one side of the lower end face of the mounting plate 5.

[0023] like Figures 2-4 As shown, it includes a displacement mechanism for adjusting the position of the mounting plate 5; The displacement mechanism includes a second lead screw guide module 24 fixedly installed on one side of the inner wall of the housing 1. A slider 20 is fixedly connected to the moving end of the second lead screw guide module 24. A rack 3 is slidably connected to one side of the slider 20. A crossbeam 2 is fixedly connected to the upper end of the rack 3. A first lead screw guide module 13 is fixedly installed on one side of the crossbeam 2. The upper end of the mounting plate 5 is fixedly connected to the moving end of the first lead screw guide module 13. A gear 21 is rotatably provided on one side of the slider 20. The gear 21 meshes with the teeth on the rack 3. A first motor 23 is fixedly connected to one side of the slider 20. The output end of the first motor 23 is fixedly connected to the gear 21. A cover 6 is rotatably provided at the top opening of the housing 1. The cover 6 is driven to rotate by a servo motor built into the housing 1.

[0024] like Figure 9 As shown, a motor 26 is fixedly connected to one end of the inner cavity of the regulating cylinder 28, and the output end of the motor 26 is fixedly connected to one end of the roller 25.

[0025] like Figure 2 and Figure 4 As shown, it includes a suction component; The suction assembly includes a liquid storage tank 7 fixedly connected to one side of the bottom of the housing 1. A water pump is installed inside the liquid storage tank 7. The water pump inlet is connected to a flexible hose 11, and the water outlet is connected to the cavity of the liquid storage tank 7. One end of the flexible hose 11 is fixedly connected to one end of the rigid pipe 10.

[0026] Specifically, in existing technologies, when phased array navigation radars operate in low-temperature rain and snow, ice and snow adhere to the antenna array surface. As a medium, ice and snow absorb and reflect electromagnetic waves, leading to a decrease in signal strength and even beam distortion, ultimately affecting the radar's detection range and accuracy. Furthermore, under repeated freeze-thaw cycles, meltwater may seep into the array surface through gaps, increasing the risk of corrosion and short circuits in antenna elements or feeder networks, thus shortening the equipment's lifespan.

[0027] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: The housing 1 is installed at a designated location on the ship. The antenna array of the main body 4 of the phased array navigation radar continuously rotates and operates, and the tilt angle of the antenna array can be dynamically adjusted.

[0028] When the phased array navigation radar main body 4 operates in low-temperature rain and snow weather, each sensor inside the antenna array independently monitors the change in dielectric constant of its corresponding area. If ice forms in a certain area, the resonant frequency of the sensor shifts. By detecting the frequency shift of each sensor, the location and area of ​​the ice formation can be determined. After the location and area of ​​the ice formation are determined, the servo motor inside the housing 1 drives the housing cover 6 to rotate 90 degrees, exposing the opening at the bottom of the housing 1. At this time, the gear 21 is rotated by the motor 23, which moves the rack 3 upward, and the mounting plate 5 is moved out of the cavity of the housing 1. The antenna array is then adjusted to be horizontal, and the mounting plate 5 is parallel to the antenna array. According to the ice formation area, the two slide plates 14 are moved back and forth or towards each other by the bidirectional screw guide module 9. Similarly, the two adjusting cylinders 28 on the same slide plate 14 are moved back and forth or towards each other by the bidirectional screw guide module 27. When the spacing between the adjusting cylinders 28 changes, the motor 26 drives the roller 25 to rotate, unwinding or winding the insulation cloth 15, keeping the exposed portion of the insulation cloth 15 taut. This allows adjustment of the size of the enclosure formed by the four insulation cloths 15, ensuring that the size of the enclosure matches the area of ​​the icing zone.

[0029] Subsequently, the lateral position of the enclosure is adjusted using lead screw guide module 13 and lead screw guide module 24 to align it with the icing area. The enclosure is then lowered and brought into contact with the antenna array. At this point, the icing area is contained. Then, the electric heating coil 39 is energized, heating the inside of the enclosure and melting the ice and snow on the antenna array. Simultaneously, a water pump inside the liquid storage tank 7 draws the melted water from the antenna array surface into the tank. This completes the de-icing process on the antenna array surface, preventing signal strength degradation and beam distortion caused by ice and snow adhering to the antenna array, which could ultimately affect the radar's detection range and accuracy. Furthermore, minimal melted water remains on the antenna array surface, preventing it from seeping into the antenna array through gaps and increasing the risk of corrosion and short circuits in the antenna elements or feeder network, thus extending the equipment's lifespan. In addition, compared to heating the entire antenna array to remove ice and snow, this solution uses a dynamically adjustable enclosure structure to enclose the icing area. Furthermore, while ensuring the icing area is enclosed, the size of the entire enclosure is minimized as much as possible, so that heat is more concentrated in the icing area. This saves resources, allows the ice and snow to melt quickly, and facilitates the extraction of meltwater.

[0030] Example 2: like Figure 10 and Figure 11 As shown, it includes a melting aid component; The melting auxiliary component includes a reciprocating rod 22 slidably disposed on one side of the bottom of the rigid tube 10. A slide rod 12 is slidably inserted into the inner cavity of the reciprocating rod 22, and a striking ball 33 is fixedly connected to the lower end of the slide rod 12.

[0031] like Figure 11 As shown, a second connecting rod 32 is rotatably mounted on one end of the reciprocating rod 22, and a first connecting rod 31 is rotatably mounted on one end of the second connecting rod 32. One end of the first connecting rod 31 is rotatably mounted on the mounting plate 5. A fourth motor 36 is fixedly connected to one side of the lower end face of the mounting plate 5, and the output end of the fourth motor 36 is fixedly connected to one end of the first connecting rod 31.

[0032] like Figure 13 As shown, one end of the slide rod 12 is fixedly connected to a spring 8, and the other end of the spring 8 is fixedly connected to one side of the inner wall of the reciprocating rod 22.

[0033] Specifically, in the above embodiments, although ice and snow can be melted quickly by heating, for large and thick intact ice layers, heat is difficult to penetrate into their interior, resulting in a slow melting rate and thus affecting the de-icing effect.

[0034] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: During the ice melting process, motor 4 (36) drives connecting rod 1 (31) to rotate continuously. This, in turn, causes connecting rod 22 (32) to move reciprocally up and down, allowing the striking ball (33) to impact the ice layer on the antenna array surface. Spring 8 provides cushioning to prevent damage to the antenna array from the impact. The striking ball (33) causes the ice layer to crack, allowing heat to be transferred more quickly into the ice, thus accelerating the melting process and improving de-icing efficiency.

[0035] Example 3: like Figures 5-7 , Figure 9 As shown, it includes a size-adaptive dewatering assembly; The size-adaptive dewatering assembly is slidably disposed on the inner connecting rod 38 and the outer connecting rod 29 on both sides of the outer wall of the adjusting cylinder 28. The inner connecting rod 38 is slidably connected to the inner sliding column 41 on both sides. The ends of the two inner sliding columns 41 on the inner connecting rod 38 are respectively fixedly connected to the inner rod 18 and the inner rod 29, and the adjacent inner rod 18 and the inner rod 29 are slidably inserted into each other. The ends of the two outer sliding columns 30 on the outer connecting rod 29 are respectively fixedly connected to the outer rod 16 and the outer rod 27, and the adjacent outer rod 16 and the outer rod 27 are slidably inserted into each other. The inner rod 18 and the inner rod 29 are in contact with the inner surface of the insulation cloth 15; the outer rod 16 and the outer rod 27 are in contact with the outer surface of the insulation cloth 15.

[0036] like Figure 9 As shown, a spring 3 40 is sleeved on one end of the inner sliding column 41. One end of the spring 3 40 is fixedly connected to the inner connecting rod 38, and the other end is fixedly connected to the end of the inner sliding column 41. A spring 2 35 is sleeved on one side of the outer sliding column 30. One end of the spring 2 35 is fixedly connected to one end of the outer rod 1 16, and the other end is fixedly connected to the outer connecting rod 29. The inner rod 1 18, inner rod 2 19, outer rod 1 16, and outer rod 2 17 clamp the insulation cloth 15 under the action of the spring 2 35 and the spring 3 40.

[0037] like Figure 6 and Figure 7 As shown, a screw guide module 4 37 and a screw guide module 34 are respectively provided on both sides of the outer wall of the adjusting cylinder 28 on one side. The moving end of the screw guide module 4 37 is fixedly connected to the inner connecting rod 38 on one side, and the moving end of the screw guide module 34 is fixedly connected to the outer connecting rod 29 on one side.

[0038] Specifically, in the above embodiments, although the icing area can be enclosed by a barrier composed of insulating cloth 15, some of the meltwater is absorbed by the insulating cloth 15 when it is extracted. This leads to problems such as fiber aging, hardening, and mold growth on the insulating cloth 15, shortening its service life and increasing the frequency of replacement and maintenance costs. Furthermore, the meltwater absorbed by the insulating cloth 15 may refreeze in low-temperature environments, causing the insulating cloth 15 to freeze and adhere to the antenna array surface. When the barrier structure is retracted or moved, it can easily cause scratch damage to the antenna array surface.

[0039] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the insulation cloth 15 is rolled up and down, the outer rod 16, outer rod 27, inner rod 18, and inner rod 29 will slide relative to each other, adapting to the length of the taut portion of the insulation cloth 15. The inner rod 18, inner rod 29, outer rod 16, and outer rod 27, under the action of spring 25 and spring 30, clamp the insulation cloth 15, thus squeezing it. During the extraction of meltwater, the inner connecting rod 38 and outer connecting rod 29 can be moved up and down by the screw guide module 4 37 and screw guide module 3 34. This allows the moisture in the insulation cloth 15 to be squeezed out by the action of the inner rod 18, inner rod 29, outer rod 16, and outer rod 27, thus preventing the insulation cloth 15 from absorbing meltwater, which could lead to fiber aging, hardening, and mold growth. This helps extend the service life of the insulation cloth 15 and reduces replacement frequency and maintenance costs. In addition, it also avoids the situation where the melted water in the insulation cloth 15 freezes again in the low temperature environment, causing the insulation cloth 15 to freeze and stick to the surface of the antenna array, which would cause scratch damage to the surface of the antenna array when the enclosure structure is taken down or moved.
