Description

Technical Field

[0001] The utility model relates to the technical field of radar reflectors, in particular to a radar reflector used in a single-point mooring system. Background Art

[0002] A radar reflector, also known as a radar transponder or radar beacon, is a passive radar auxiliary device that does not actively transmit signals. However, when radar waves hit it, it can reflect a strong radar echo, thus forming a distinct bright spot or mark on the radar screen. In a single-point mooring system, the buoy is a key fixed point used to connect the ship and the seabed. The radar reflector installed on the buoy can clearly mark the position of the buoy on the radar screen, allowing the ship to accurately identify and approach the buoy for mooring operations from a distance.

[0003] The radar reflectors commonly used in single-point mooring systems are spherical in shape. Due to the special structure of spherical radar reflectors, they are very difficult to transport. For example, patent publication No. CN211375044U discloses a spherical marine radar reflector. This achieves efficient spherical signal reflection when the entire radar reflector is in operation and allows for easier transport of the entire radar reflector when not in use. However, manual storage and adjustment are required, and the spherical radar reflector is relatively large, making adjustment more laborious. Utility Model Content

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The present invention provides an embodiment of a radar reflector for a single-point mooring system, comprising a base plate 1, a first reflector 6, a second reflector 8, and a radar reflector body 20. An adjustment cylinder 3 is provided at the center of the top of the base plate 1, and a lifting sleeve 4 is provided inside the adjustment cylinder 3. A housing 11 is fixed to the top of the lifting sleeve 4, and the radar reflector body 20 is provided on the top of the housing 11.

[0021] The bottom plate 1 is fixedly connected to the buoy of the single point mooring system. The bottom end of the adjusting cylinder 3 is provided with a first rotary drive mechanism 5, and the output end of the first rotary drive mechanism 5 is provided with a screw rod 13. The lifting sleeve 4 is threadedly connected to the screw rod 13.

[0022] The first rotary drive mechanism 5 can drive the screw rod 13 to rotate, so that the lifting sleeve 4 rises along the screw rod 13, thereby adjusting the height position of the radar reflector body 20, thereby increasing the signal strength;

[0023] Guide blocks 15 are provided on both sides of the lifting sleeve 4, and guide grooves 14 are provided on both sides of the interior of the adjusting cylinder 3 to guide and limit the lifting sleeve 4;

[0024] The radar reflector body 20 includes a second reflector 8 and a first reflector 6 , wherein the bottom of the second reflector 8 is connected to the housing 11 , and the first reflector 6 is disposed inside the second reflector 8 via a rotating shaft 7 ;

[0025] The first reflector 6 and the second reflector 8 are both semicircular structures, and the surfaces of the first reflector 6 and the second reflector 8 are both coated with a silver film;

[0026] The bottom end of the rotating shaft 7 extends into the housing 11. A driven gear 12 is provided at the bottom of the rotating shaft 7. A second rotary drive mechanism 9 is provided on one side of the housing 11. The output end of the second rotary drive mechanism 9 is provided with a driving gear 10 that meshes with the driven gear 12 through a roller.

[0027] The second rotary drive mechanism 9 drives the driving gear 10 to rotate, causing the driven gear 12 and the rotating shaft 7 to rotate, driving the first reflector 6 to rotate within the second reflector 8, so that the radar reflector body 20 forms a spherical structure with omnidirectional reflection capability. The radar reflector body 20 can be marked on the radar screen, allowing the ship operator to easily determine the precise position of the buoy and adjust the ship's course and speed accordingly to achieve precise mooring.

[0028] When transport is required, the second rotary drive mechanism 9 can be rotated in the opposite direction to drive the first reflector 6 to rotate to the inside of the second reflector 8, thereby reducing the overall size of the radar reflector body 20. At the same time, the operation is simple and there is no need for manual unfolding and folding, which saves time and effort.

[0029] Support cylinders 2 are provided on both sides of the top of the bottom plate 1, and support rods 17 are provided inside the support cylinders 2. The top ends of the support rods 17 are connected to the adjustment cylinders 3.

[0030] The bottom end of the support tube 2 is provided with a damping block 18, and the top of the damping block 18 is provided with a pressure piece 19 through a rigid spring 16, and the top of the pressure piece 19 is connected to the support rod 17;

[0031] If the radar reflector body 20 shakes due to environmental factors such as waves and wind, the adjustment tube 3 generates lateral pressure on the support rod 17, causing the pressure piece 19 at the end of the support rod 17 to squeeze the rigid spring 16 in the support tube 2, causing the rigid spring 16 to deform and store a certain amount of energy;

[0032] When the external force disappears, the rigid spring 16 will return to its original shape and release the stored energy, generating a force in the opposite direction to offset the external force. At the same time, when the structure is vibrated, the damping block 18 will deform accordingly. Through the energy dissipation effect of its damping material, the transmission and accumulation of vibration energy is reduced, and the change in the direction of the reflected wave caused by the shaking of the radar reflector body 20 is reduced, thereby improving the accuracy and reliability of radar detection.

[0033] Limiting grooves are provided on both sides of the support tube 2, and limiting blocks are provided on both sides of the pressure piece 19 to guide and limit the rigid spring 16 so that it is not easily twisted or deflected.

[0034] The specific models and specifications of the first rotary drive mechanism 5 and the second rotary drive mechanism 9 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is existing technology and will not be described in detail.

[0035] Working principle: When the embodiment of the present application is in use, the bottom plate 1 is fixedly connected to the buoy of the single-point mooring system, and the radar reflector body 20 is composed of a first reflector 6 and a second reflector 8. When in use, the second rotary drive mechanism 9 drives the active gear 10 to rotate, so that the driven gear 12 and the rotating shaft 7 rotate, driving the first reflector 6 to rotate inside the second reflector 8, so that the radar reflector body 20 forms a spherical structure with omnidirectional reflection capability. The radar reflector body 20 can be marked on the radar screen, and the ship driver can easily determine the exact position of the buoy and adjust the ship's course and speed accordingly to achieve precise mooring. When it needs to be transported, the second rotary drive mechanism 9 can be rotated in the opposite direction to drive the first reflector 6 to rotate to the inside of the second reflector 8, thereby reducing the overall size of the radar reflector body 20. At the same time, the operation is simple, and there is no need for manual unfolding and storage, which saves time and effort. The first rotary drive mechanism 5 can drive the screw rod 13 to rotate, so that the lifting sleeve 4 rises along the screw rod 13, thereby adjusting the height position of the radar reflector body 20, thereby improving the signal strength. In addition, if the radar reflector body 20 shakes due to environmental factors such as waves and wind, the adjusting tube 3 generates lateral pressure on the support rod 17, so that the pressure piece 19 at the end of the support rod 17 squeezes the rigid spring 16 in the support tube 2, and the rigid spring 16 deforms and stores a certain amount of energy. When the external force disappears, the rigid spring 16 will return to its original shape and release the stored energy, generating a force in the opposite direction to offset the external force. At the same time, when the structure is vibrated, the damping block 18 will deform accordingly. Through the energy dissipation effect of its damping material, the transmission and accumulation of vibration energy is reduced, and the change in the direction of the reflected wave caused by the shaking of the radar reflector body 20 is reduced, thereby improving the accuracy and reliability of radar detection.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
