Description

Technical Field

[0001] This invention belongs to the field of shipborne radar technology, specifically a high-precision and stable installation device for shipborne radar. Background Technology

[0002] Shipborne radar is a radio detection and ranging device installed on a ship that uses radio waves to detect targets (such as other ships, coastlines, navigation buoys, icebergs, etc.) and determine their distance, bearing, and speed. To ensure the stability of shipborne radar, it needs to be installed in a designated location on the ship using mounting equipment.

[0003] In existing technologies, shipborne radars are typically mounted on radar masts or mounting racks using bolts, screws, and other connectors. While this method ensures stable installation, during actual use, dust, plastic debris, and other foreign objects often accumulate on the radar's surface. These deposits directly attenuate and scatter radar waves, leading to reduced detection range, weakened target echoes, and even the loss of weak targets. In severe cases, the signal loss can reach several decibels, rendering the radar unable to provide accurate and reliable situational awareness in critical collision avoidance scenarios such as dense fog or nighttime. Maintaining radar surface cleanliness through regular manual cleaning is also time-consuming and labor-intensive. Summary of the Invention

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The high-precision and stable installation device for shipborne radar described in this invention utilizes a foreign object sensing component and a foreign object removal component. It can detect in real time whether there are foreign objects attached to the radar surface through pressure sensing. When there are foreign objects on the radar surface, multiple scrapers work together to push the foreign objects off, thereby avoiding the attenuation and scattering effects of foreign objects such as dust and plastic waste attached to the radar surface, which would lead to a shortened radar detection range, weakened target echo, or even loss of weak targets. This ensures that the radar can continuously and accurately perceive the surrounding situation.

[0023] 2. The high-precision stable installation device for shipborne radar described in this invention utilizes a material collection component. When foreign objects are scraped by the scraper, they are simultaneously gathered by a cylindrical structure. Due to the gathering and spiral compression within the cylindrical structure, the volume of the foreign objects is significantly compressed, making the structure compact and less prone to loosening and dispersing under wind force. This effectively prevents foreign objects from being blown up by the wind and re-attaching to the radar surface, ensuring the long-term stable and reliable operation of the radar. Simultaneously, the unified discharge method ensures a relatively fixed accumulation position for foreign objects, greatly facilitating centralized cleanup by personnel and avoiding the problem of difficult cleanup caused by foreign objects scattering around.

[0038] Please refer to Figures 1-10The present invention provides a technical solution: a high-precision stable installation device for shipborne radar, including a support column 1 and an installation plate 4 for installing radar, the support column 1 is fixedly connected to the top of the support plate 3, and a foreign object sensing component is provided between the support plate 3 and the installation plate 4.

[0040] The support column 1 is equipped with a foreign object removal component;

[0042] like Figure 2 and Figure 3 As shown, the support column 1 is equipped with an adjustment structure for adjusting the position of the cover cylinder 5;

[0043] The adjustment structure includes a rotating ring 2 rotatably sleeved on one side of the support column 1, a flip plate 6 rotatably connected to one end of the rotating ring 2, a slider 13 slidably connected to one side of the flip plate 6, and one end of the slider 13 fixedly connected to one side of the outer wall of the cover cylinder 5.

The gear 14 meshes with the tooth blocks on the gear ring 15. A motor 34 is fixedly connected to one side of the support column 1. The output end of the motor 34 is fixedly connected to the gear 14.

[0045] like Figure 3 and Figure 4 As shown, a second motor 16 is fixedly connected to one end of the rotating ring 2, and the output end of the second motor 16 is fixedly connected to one end of the flip plate 6. A lead screw 12 is threadedly connected to one end of the slider 13, and both ends of the lead screw 12 are rotatably connected to the flip plate 6. A first motor 11 is fixedly connected to one end of the flip plate 6, and the output end of the first motor 11 is fixedly connected to one end of the lead screw 12.

[0046] like Figure 6and Figure 7 As shown, the cover cylinder 5 is equipped with a synchronous transmission assembly for driving multiple gathering plates 23 to move simultaneously.

[0047] The synchronous transmission assembly includes a lifting ring 18 and a connecting ring 28. A guide rod 30 is fixedly connected to one side of the lifting ring 18. The guide rod 30 slides through one side of the outer wall of the cover cylinder 5. Multiple sliding rods 17 are evenly slidably connected to the lower surface of the lifting ring 18 in the circumferential direction. The end of the sliding rod 17 away from the gathering plate 23 is rotatably connected to a connecting rod 35. The ends of the multiple connecting rods 35 away from the sliding rod 17 are rotatably connected to the connecting ring 28.

[0048] like Figure 7 As shown, a cylinder 31 is fixedly connected to one side of the lifting ring 18. The piston end of the cylinder 31 is fixedly connected to one side of the edge of the connecting ring 28. A cylinder 29 is fixedly connected to one side of the outer wall of the cover cylinder 5. The piston end of the cylinder 29 is fixedly connected to one side of the lifting ring 18.

[0049] Specifically, in existing technologies, shipborne radar is often mounted on a radar mast or mounting bracket using bolts, screws, and other connectors. While this method ensures stable installation, in actual use, dust, plastic debris, and other foreign objects often adhere to the radar's surface. These deposits directly attenuate and scatter radar waves, leading to reduced detection range, weakened target echoes, and even the loss of weak targets. In severe cases, the signal loss can reach several decibels, making it impossible for the radar to provide accurate and reliable situational awareness in critical collision avoidance scenarios such as dense fog and nighttime. Maintaining the cleanliness of the radar surface through regular cleaning by personnel is also time-consuming and labor-intensive.

[0050] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0051] This design is applied to a dome-shaped radar with a cylindrical body and a curved top. The support column 1 is installed at a designated location on the ship, and the radar is bolted to the center of the mounting plate 4, with the radar and mounting plate 4 aligned on the same axis. After the radar is installed on the mounting plate 4, the mounting plate 4 will move downwards due to its increased weight, compressing the spring 9 and retracting the damper 10. The end of the pressure rod 7 presses against the detection end of the pressure sensor 8. At this point, the pressure sensor 8 obtains an initial pressure value, which is defined as the standard value. This pressure value corresponds to the weight of the radar.

[0052] When the radar is in daily use, if there are no foreign objects attached to the radar surface, the standard value will not change, and the flip plate 6 will be in a horizontal state. The structure such as the cover tube 5 will not be higher than the radar and will not affect the radar's signal transmission and reception.

[0053] If foreign objects adhere to the radar surface and accumulate to a certain quantity, the standard value increases. At this point, motor 2 (16) drives the flip plate 6 to rotate 90 degrees, turning it into a vertical position. The cover cylinder 5 then aligns with the radar axis. Subsequently, motor 11 drives the lead screw 12 to rotate, causing the slider 13 to slide downwards until the scraper 32 is flush with the top of the radar. Then, cylinder 2 (31) drives the connecting ring 28 upwards, allowing multiple connecting rods 35 to simultaneously drive multiple sliding rods 17 to slide radially, ensuring the scraper 32 adheres to the radar surface. Next, cylinder 1 (29) drives the lifting ring 18 downwards, causing the scraper 32 to move downwards along the radar surface. Furthermore, the distance between the scraper 32 and the radar axis can be adjusted in real-time to accommodate changes in radar curvature.

[0054] As the scraper 32 moves downwards, it removes foreign objects adhering to the radar surface. Each time the scraper 32 reaches the bottom of the radar, it is driven to return to its original position. Then, the motor 34 drives the gear 14 to rotate, which in turn rotates the rotating ring 2 through the transmission between the gear 14 and the gear ring 15, thus changing the angle of the scraper 32. This scraping action is repeated to achieve comprehensive scraping of the radar surface. Once the pressure sensor 8 detects a return to the standard value, it indicates that there are no foreign objects on the radar surface, and then the flip plate 6 resets. This avoids the attenuation and scattering effects of dust, plastic debris, and other foreign objects adhering to the radar surface, which could lead to reduced radar detection range, weakened target echo, or even loss of weak targets. This ensures that the radar can continuously and accurately perceive its surroundings.

[0055] Example 2:

[0056] In the above embodiments, although foreign objects on the radar surface can be scraped off, the scraped foreign objects will be scattered around the bottom of the support column 1. This is not only not conducive to personnel cleaning, but also makes it easy for foreign objects to re-attach to the radar surface under the action of wind, resulting in repeated foreign object removal work and affecting the normal operation of the radar.

[0057] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0058] like Figure 5 , Figure 8 , Figure 9 As shown, the cover cylinder 5 is equipped with a collection assembly for gathering foreign objects;

[0059] The material gathering assembly includes a winding shaft 33 rotatably connected to one end of the inner cavity of the gathering plate 23. A gathering cloth 24 is wound on the winding shaft 33. The gathering cloth 24 slides through the side wall of the gathering plate 23. The end of the gathering cloth 24 is fixedly connected to the side wall of another adjacent gathering plate 23. A circular through hole 21 is opened in the middle of the upper end of the cover cylinder 5. A riser pipe 26 communicating with the circular through hole 21 is fixedly connected to the middle of the upper end face of the cover cylinder 5. A spiral shaft 20 is rotatably connected to the upper end of the inner cavity of the riser pipe 26. The surface of the spiral shaft 20 is provided with spiral blades. The spiral shaft 20 extends through the circular through hole 21 into the inner cavity of the cover cylinder 5. A disc 22 is fixedly connected to one end of the spiral shaft 20 located in the inner cavity of the cover cylinder 5.

[0060] like Figure 8 As shown, a motor 36 is fixedly connected to one end of the gathering plate 23, and the output end of the motor 36 is fixedly connected to one end of the winding shaft 33.

[0061] like Figure 6 As shown, a motor 27 is fixedly connected to one end of the outer wall of the riser tube 26, and the output end of the motor 27 is fixedly connected to one end of the spiral shaft 20.

[0062] like Figure 6 As shown, one end of the riser pipe 26 is connected to the discharge pipe 25.

[0063] Specifically, after the cover cylinder 5 is aligned with the radar, it is driven down to fit against the edge of the mounting plate 4, at which point the cover cylinder 5 completely covers the radar. Then, the scraper 32 is driven to scrape away foreign objects from the radar surface from bottom to top. In addition, multiple gathering plates 23 and gathering cloth 24 cooperate to form a retractable and expandable cylindrical structure. During the process of the scraper 32 scraping away foreign objects, when the distance between the scraper 32 and the radar axis changes, the motor 5 36 drives the winding shaft 33 to rotate, winding or unwinding the gathering cloth 24 to keep it taut. The foreign objects scraped by the scraper 32 will then gather in the cylindrical structure. As the foreign objects rise continuously in the cylindrical structure, when the gathering plate 23 fits against the edge of the disc 22, the cylindrical structure wraps around the spiral shaft 20, and the foreign objects are all within the conveying range of the spiral shaft 20. As the foreign objects gather towards the spiral shaft 20 under the action of the cylindrical structure, the foreign objects will also be tightly packed together, thus compressing the volume.

[0064] Subsequently, the screw shaft 20 is rotated by motor 27, causing the compressed foreign objects to move upwards. When the foreign objects reach the discharge pipe 25, they are discharged uniformly along the pipe. At this point, the foreign objects that have fallen around the support column 1 are not only concentrated, but also significantly compressed in volume due to the gathering and screw compression within the cylindrical structure, making the structure compact. Therefore, they are not easily scattered by wind, effectively preventing them from being blown up by the wind and re-attaching to the radar surface, ensuring the long-term stable and reliable operation of the radar. Simultaneously, the uniform discharge method keeps the foreign objects in a relatively fixed position, greatly facilitating one-time centralized cleanup and avoiding the problem of difficult cleanup caused by scattered foreign objects.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
