Description

Technical Field

[0001] This application relates to the field of millimeter-wave radar, and in particular to a millimeter-wave radar device for ship collision avoidance. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band. It features small size, light weight, and high spatial resolution. Furthermore, millimeter-wave seekers have a strong ability to penetrate fog, smoke, and dust. Millimeter-wave radar has been applied in many important civilian and military systems.

[0003] Millimeter-wave radar is also used in shipping. Equipping ships with millimeter-wave radar can detect the conditions around the ship in a timely manner and reduce the occurrence of objects colliding with the ship.

[0004] During transportation, ships may encounter severe weather conditions, such as strong winds. In such cases, the ship will be moved and swayed by the water and wind, and the cargo on board will also tilt and move. When the cargo moves, it is very likely to collide with the millimeter-wave radar device, causing damage to the millimeter-wave radar device and making it difficult to continue monitoring the area around the ship. Therefore, this needs to be improved. Summary of the Invention

[0005] To improve the stability of millimeter-wave radar during use, this application provides a ship collision avoidance millimeter-wave radar device.

[0006] The technical solution of the ship collision avoidance millimeter-wave radar device provided in this application is as follows:

[0007] A millimeter-wave radar device for ship collision avoidance includes a millimeter-wave radar body and a mounting housing. The mounting housing is externally protected by a protective shell. A connecting plate is located at the lower end of the mounting housing, and a mounting platform is located above the connecting plate. The millimeter-wave radar body is positioned above the mounting platform. The mounting housing has a insertion slot. The connecting plate has a connecting rod rotatably connected to a limit rod, which is inserted into the insertion slot. The insertion slot has an abutment block that abuts against the limit rod. The connecting plate has an elastic element located below the protective shell, which abuts against the limit rod. The side wall of the mounting housing has a sliding groove, and the mounting housing has a sliding block inserted into the sliding groove. Positioning elements are located in the sliding block and the sliding groove.

[0008] By adopting the above technical solution, when the mounting box is hit, the limiting rod rotates and slides off the abutment block. At this time, the elasticity of the elastic element causes the elastic element to drive the protective shell to rise, thereby protecting the millimeter-wave radar device in the protective shell. This reduces the occurrence of debris around the mounting box hitting the millimeter-wave radar device, thereby improving the stability of the millimeter-wave radar device during use.

[0009] Preferably, the positioning element includes a magnetic element and an adsorption element, wherein the magnetic element is connected to the sliding block and the adsorption element is connected to the inner wall of the sliding groove.

[0010] By adopting the above technical solution, when the protective shell rises, the sliding block slides and rises synchronously in the sliding groove. After the sliding block rises to the upper end of the sliding groove, the magnetic component and the adsorption component of the sliding block attract each other through magnetic force, thereby positioning the protective shell and improving the stability of the protective shell. At the same time, it is convenient to reset the protective shell.

[0011] Preferably, the connecting plate is provided with a mounting plate, the mounting plate has a connecting groove, a closing plate is inserted into the connecting groove, the closing plate can close the protective shell, and the mounting plate and the protective shell are jointly provided with a driving component for driving the closing plate to move.

[0012] By adopting the above technical solution, after the protective shell rises, the driving component drives the closing plate to move and rotate, thereby closing the protective shell and isolating the protective shell, connecting box and external barrier, further improving the safety performance of the millimeter-wave radar body.

[0013] Preferably, the driving component includes a synchronization plate, a connecting block, and a rotating rod. The connecting block is inserted into a connecting groove and can slide in the connecting groove. The rotating rod is rotatably connected to the connecting block. The closing plate is connected to the rotating rod. The synchronization plate is connected to the protective housing and the synchronization plate is connected to the connecting block.

[0014] By adopting the above technical solution, the protective shell rises while driving the synchronous plate to rise synchronously. The synchronous plate drives the connecting block to slide in the connecting groove and rise together. The closing plate rises synchronously. After the closing plate slides along the height direction of the sliding groove, it extends out of the sliding groove. When the protective shell rises to the point where the magnetic component and the adsorption component attract and stick to each other, the closing plate extends out of the sliding groove. At the same time, the rotating rod rotates and causes the closing plate to rotate, closing the protective shell, thereby improving the stability of the protective shell.

[0015] Preferably, a guide block is provided in the connecting groove, and the guide block is provided with a guide surface.

[0016] By adopting the above technical solution, the guide surface is designed so that the closing plate tilts after it comes into contact with the guide surface during the rising process, so that after the closing plate extends out of the connecting groove, it tilts down under the action of gravity and protects the protective shell.

[0017] Preferably, a lifting plate is provided above the mounting platform, the millimeter-wave radar body is connected to the lifting plate, the connecting plate is provided with a driving device for driving the lifting plate to rise and fall, and a stabilizing component is provided above the connecting plate to improve the stability of the lifting plate.

[0018] By adopting the above technical solution, after the drive device is started, the lifting plate causes the millimeter-wave radar body to rise, thereby adjusting the height of the millimeter-wave radar body and thus improving the detection range of the millimeter-wave radar body.

[0019] Preferably, the driving device includes a drive motor, a drive rod, a swing rod, and a synchronizing rod. The drive motor is located above the connecting plate. One end of the drive rod is welded and fixed to the coupling of the drive motor. The swing rod is connected to the drive rod and rotatably connected to the synchronizing rod. A clearance hole is provided through the surface of the mounting platform. The synchronizing rod passes through the clearance hole and is connected to the lifting plate.

[0020] By adopting the above technical solution, after the drive motor starts, it drives the rotating rod to rotate, which in turn causes the swing rod to drive the synchronous rod to rotate, thereby enabling the lifting plate to move along the height direction of the protection device, so as to adjust the height of the lifting plate and thus adjust the height position of the millimeter-wave radar body.

[0021] Preferably, the support platform is provided with a positioning hole, and the lifting plate is provided with a positioning rod inserted into the positioning hole, wherein the positioning rod is adapted to the positioning hole.

[0022] By adopting the above technical solution, during the lifting plate's ascent or descent, the positioning rod slides in the positioning hole, and the outer wall of the positioning rod adapts to the inner wall of the positioning hole, thereby making the lifting plate more stable during ascent or descent, reducing phenomena such as shaking during ascent or descent, and making the data collected by the millimeter-wave radar body during detection more accurate.

[0023] Preferably, the stabilizing component includes a synchronizing element, a drive screw, a guide rod, a fixing plate, and a snap-fit ​​plate. The fixing plate is connected to the mounting housing. The drive screw passes through the fixing plate and is rotatably connected to the fixing plate. The guide rod passes through the fixing plate. The snap-fit ​​plate is sleeved on the drive screw and the guide rod. The lifting plate has a snap-fit ​​groove for the fixing plate to be inserted. The synchronizing element is used to drive the drive screw to rotate.

[0024] By adopting the above technical solution, the drive screw is rotated by the synchronization component, which causes the locking plate to move along the length direction of the drive screw. After the lifting plate rises, the locking plate moves and is inserted into the locking groove of the lifting plate, thereby improving the stability of the lifting plate.

[0025] Preferably, the synchronizing element includes a first driving bevel gear, a first driven bevel gear, a second driving bevel gear, a second driven bevel gear, and a driven rod. The first driving bevel gear is sleeved on the driving rod, the first driven bevel gear meshes with the first driving bevel gear, the driven rod is connected to the first driven bevel gear, the second driving bevel gear is sleeved on the driven rod, the second driven bevel gear is sleeved on the driving screw, and the second driving bevel gear meshes with the second driven bevel gear.

[0026] By adopting the above technical solution, when the drive rod rotates, it drives the first active bevel gear to rotate synchronously, thereby causing the first driven bevel gear meshing with the first active bevel gear to rotate. The driven rod follows the rotation of the first driven bevel gear, and causes the second active bevel gear to rotate together with the driven rod, causing the second driven bevel gear meshing with the second active bevel gear to rotate, and driving the drive screw to rotate, so that the locking plate moves along the length direction of the drive screw and locks into the locking groove of the lifting plate. When the lifting plate rises synchronously, the locking plate moves synchronously, thereby improving the stability of the lifting plate after it moves.

[0027] Preferably, the snap-fit ​​plate is provided with a guide surface.

[0028] By adopting the above technical solution and setting the guide surface, the closing plate can be more stable during the rising process, and the phenomenon of the closing plate being difficult to rotate after rising is reduced, thereby improving the protective effect of the closing plate on the protective shell.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. When the ship is swaying severely during transportation, the limit rod will slide from above the abutment block after being impacted. After the elastic element separates from the limit rod, the elastic force of the elastic element will drive the protective shell to rise. At the same time, the sliding block will rise along the height direction of the sliding groove and finally be fixed by the positioning element so that the protective shell can protect the millimeter-wave radar body, thereby improving the safety of the millimeter-wave radar body during ship transportation.

[0031] 2. When the protective shell rises, it drives the synchronous plate to rise simultaneously. After the synchronous plate lifts the connecting block, the closing plate slides out of the connecting groove and tilts and rotates to cover the top of the protective shell, further improving the protection effect on the millimeter-wave radar body.

[0032] 3. After starting the drive motor, the drive lever drives the swing plate to rotate, and the synchronous rod drives the lifting plate to rise or fall, so as to adjust the position of the millimeter-wave radar device body and improve the detection range of the millimeter-wave radar device.

[0051] The implementation principle of a ship collision avoidance millimeter-wave radar device according to an embodiment of this application is as follows:

[0052] When the mounting housing 2 collides, the limiting rod 42, which is abutting against the abutment block 211, slides to the lower end of the sliding groove 22. At this time, under the elastic force of the elastic element 43, the elastic element 43 drives the protective housing 3 to rise. When the sliding block 31 rises to the top wall of the sliding groove 22, the magnetic element 321 and the adsorption element 322 attract and stick to each other to fix the protective housing 3, thereby reducing the occurrence of external objects colliding with the millimeter-wave radar body 1 and improving the stability of the millimeter-wave radar body 1.

[0053] As the protective housing 3 rises, the synchronous plate 531 drives the connecting block 532 to rise synchronously, causing the rotating rod 533 to drive the closing plate 52 to rise. After the protective housing 3 is fixed, the closing plate 52 rotates at the same time and closes the protective housing 3, further improving the stability of the millimeter-wave radar body 1.
