Description

Technical Field

[0002] A ship is a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats. They are collectively called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-provided energy. The composition of the ship includes the ship radar mast.

[0003] When using the above technology, it was found that the following technical problems exist in the existing technology: during the assembly process of the ship's radar mast, due to its large structural size and the installation position usually located high on the ship's superstructure, it is necessary to fine-tune the height and pitch angle of the radar equipment. By precisely adjusting the radar, it is effectively ensured that the radar system can maintain stable scanning accuracy under different sea conditions, thereby providing reliable situational awareness data for ship navigation, target detection and collision avoidance decisions. Reasonable radar angle adjustment can also optimize the radar's detection blind spot and enhance its detection capability of low-altitude targets on the sea surface. This has important engineering practical significance for ensuring the safety of ship navigation. To this end, we designed a radar mast adjustment tooling to provide another technical solution to the above technical problems. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In order to enable those in the technical field to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings.

[0022] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0023] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Embodiment 1 Please refer to Figures 1 - 7 , an adjustment tool for a radar mast, including a ship deck 1. The top of the ship deck 1 is fixedly connected by bolts with a support tool 2. The top of the support tool 2 is equipped with a support platform 10. The top of the support platform 10 is rotatably connected with an adjustment seat 3. The top of the adjustment seat 3 is rotatably connected with an adjustment arm 6. An electric push rod is assembled inside the adjustment arm 6. The output end of the electric push rod is fixed to a telescopic rod 8. The telescopic rod 8 is slidably connected inside the adjustment arm 6. One end of the telescopic rod 8 away from the adjustment arm 6 is fixed with a radar 9. An elevating mechanism for adjusting the height of the radar 9 is arranged inside the support tool 2; When in use, the support tool 2 is installed on the ship deck 1 at a high position of the ship superstructure through bolts. The top of the support tool 2 is equipped with a support platform 10, an adjustment seat 3, an adjustment arm 6, a telescopic rod 8 and a radar 9. When the elevating mechanism is started to drive the support platform 10, the adjustment seat 3, the adjustment arm 6, the telescopic rod 8 and the radar 9 to move upward significantly, so as to adjust to the most suitable height for ship navigation and detection. At the same time, the support platform 10 and the adjustment seat 3 rotate, so as to effectively drive the radar 9 to adjust and detect at different azimuth angles. The adjustment arm 6 and the adjustment seat 3 rotate, so that the adjustment arm 6 drives the telescopic rod 8 and the radar 9 to expand, which is convenient for effectively and precisely adjusting the radar 9 finely. Therefore, by rotating the adjustment seat 3 and the support platform 10, and the adjustment arm 6 is vertically adjusted with respect to the adjustment seat 3, so as to effectively and precisely adjust the azimuth and fine height difference of the radar 9 detection, so as to ensure that the radar system can maintain a stable scanning accuracy under different sea conditions, and thus provide reliable situation awareness data for ship navigation, target detection and collision avoidance decision-making. A reasonable radar angle adjustment can also optimize the detection blind area of the radar and improve its detection ability for low-altitude targets on the sea surface, which has important engineering practical significance for ensuring the navigation safety of ships; The lifting mechanism includes a guide rod 14, a threaded cylinder 15, a lifting screw rod 16, and a high-torque motor 18. Guide rods 14 are fixed to the four ends of the bottom end of the support platform 10. The outer side of the bottom end of the guide rod 14 is slidably connected to the top end of the support tooling 2. A chassis base 19 is fixed to the bottom end of the guide rod 14. A threaded cylinder 15 is fixed to the bottom end of the support platform 10. The outer side of the threaded cylinder 15 is slidably connected to the top end of the support tooling 2. The bottom end inside the threaded cylinder 15 is threadedly connected to the lifting screw rod 16. A high-torque motor 18 is fixed to the top end of the ship deck 1 and inside the support tooling 2. The output end of the high-torque motor 18 is fixed to the lifting screw rod 16; Specifically, when it is necessary to raise the radar 9 significantly to facilitate the detection of distant targets, therefore, the high-torque motor 18 is started to drive the lifting screw rod 16 to rotate. The guide rod 14 effectively guides the support platform 10, and the support tooling 2 effectively prevents the guide rod 14 from rotating. At this time, the threaded cylinder 15 and the support platform 10 driven by the lifting screw rod 16 move upward, and the support platform 10 effectively and stably raises and lowers the adjustment seat 3, the adjustment arm 6, the telescopic rod 8, and the radar 9 according to the guidance of the guide rod 14, so as to effectively raise and lower the radar 9 significantly, thereby ensuring the accuracy of the radar 9 detection; A reinforcement seat 17 is fixed to the top end of the ship deck 1 and inside the support tooling 2. The inside of the reinforcement seat 17 is fixed to the high-torque motor 18. The high-torque motor 18 is effectively fixed by the reinforcement seat 17, and the vibration generated by the output of the high-torque motor 18 is stably supported by the reinforcement seat 17 for the high-torque motor 18; The inside of the chassis base 19 is slidably connected to the outer sides of the lifting screw rod 16 and the threaded cylinder 15. The bottom end of the guide rod 14 is effectively connected by the chassis base 19, so as to facilitate the chassis base 19 to reinforce the guide rod 14 and prevent the bottom end of the guide rod 14 from deforming. The chassis base 19 slides with the threaded cylinder 15 and the guide rod 14. This method effectively connects the four guide rods 14 while reasonably avoiding the movement trajectories between the guide rod 14 and the threaded cylinder 15; A horizontal rotation mechanism for adjusting the angle of the radar 9 is provided between the support platform 10 and the adjustment seat 3. The horizontal rotation mechanism includes a servo motor II 11, a transmission gear 12, and an L-shaped frame 13. An L-shaped frame 13 is fixed to one end of the bottom end of the support platform 10. A servo motor II 11 is fixed to the bottom end of the L-shaped frame 13. The output end of the servo motor II 11 passes through the L-shaped frame 13 and is fixed with a transmission gear 12. The outer side of the transmission gear 12 is meshed with the adjustment seat 3 A meshing internal gear ring is fixed to the bottom end inside the adjustment seat 3, and the meshing internal gear ring is meshed with the transmission gear 12; Specifically, when the ship is in motion, the radar 9 detects the scanning radius around the ship. Therefore, the servo motor two 11 is activated to drive the transmission gear 12 to rotate. The transmission gear 12 meshes with the meshing internal gear ring, causing the adjusting seat 3 to drive the adjusting arm 6, the telescopic rod 8, and the squeezing arm 7 to rotate, so as to effectively scan and detect the radius around the ship.

[0025] Embodiment Two Please refer to Figures 8 - 10 As shown in the figure, an adjusting tooling for a radar mast is provided. At the top of the adjusting seat 3, there is an unfolding mechanism for folding the radar 9. The unfolding mechanism includes a servo motor one 4, an adjusting screw rod 5, an adjusting arm 6, and a squeezing arm 7. At one end of the top of the adjusting seat 3, a shaft seat 21 is fixed. The inner side of the shaft seat 21 is rotatably connected with the adjusting arm 6. At the bottom end of the adjusting arm 6 away from the shaft seat 21, the squeezing arm 7 is rotatably connected. At the end of the squeezing arm 7 away from the adjusting arm 6, a sliding seat 20 is rotatably connected. The bottom end of the sliding seat 20 is slidably connected with the adjusting seat 3. The adjusting screw rod 5 is rotatably connected to the top of the adjusting seat 3. The outer side of the adjusting screw rod 5 is threadedly connected with the sliding seat 20. At one end of the adjusting seat 3, the servo motor one 4 is fixed. The output end of the servo motor one 4 is fixed to the adjusting screw rod 5. Specifically, by activating the servo motor one 4 to drive the adjusting screw rod 5 to rotate, the adjusting screw rod 5 drives the sliding seat 20 to reciprocate along the guide of the adjusting seat 3. The sliding seat 20 squeezes and pulls the squeezing arm 7. Through the pulling and squeezing of the squeezing arm 7, the adjusting arm 6 effectively moves around the shaft seat 21 as the axis, causing the adjusting arm 6 to drive the radar 9 to be adjusted up and down. When the sliding seat 20 moves towards the shaft seat 21, at this time, the adjusting arm 6 drives the radar 9 to contract downward. Conversely, when the sliding seat 20 moves away from the shaft seat 21, the adjusting arm 6 drives the radar 9 to be adjusted upward and unfolded, so as to scan and detect the surrounding area during the ship's movement. Therefore, the accuracy and flexibility of the radar 9 detection are maximally increased.

[0026] The usage process of an adjusting tooling for a radar mast provided by the present invention is as follows: When in use, a high-torque motor 18 is used to drive the lifting screw rod 16 to rotate. Through the threaded cooperation between the threaded barrel 15 and the screw rod, the support platform 10 is driven to move vertically. The sliding fit between the four groups of guide rods 14 and the support tooling 2 forms a rigid guiding structure to ensure the stability of the lifting process. The chassis seat 19 laterally reinforces the bottom ends of the guide rods 14 to prevent the deformation of the rods caused by the torque of the screw rod, realizing a large-range and precise adjustment of the radar height. The servo motor II 11 meshes with the internal gear ring of the adjustment seat 2 through the transmission gear 12, driving the adjustment seat to rotate 360° horizontally, so as to effectively detect the surrounding of the ship. In cooperation with the servo motor I 4, the adjustment screw rod 5 is driven to rotate, and the adjustment screw rod 5 drives the sliding seat 20 to reciprocate along the guide of the adjustment seat 3. The sliding seat 20 squeezes and pulls the extrusion arm 7. Through the traction and extrusion of the extrusion arm 7, the adjustment arm 6 is effectively moved with the axis seat 21 as the axis, so that the adjustment arm 6 drives the radar 9 to perform vertical pitch adjustment, thereby realizing the dynamic expansion of the radar detection radius; Through the deep coupling of mechanical transmission and the electronic control system, this tooling realizes the three-dimensional precise adjustment of the radar height, horizontal azimuth and pitch angle, maximally reduces the radar detection blind area, significantly improves the capture rate of low-altitude / seasurface targets, and provides all-weather situation awareness guarantee for the ship.
