Technical Field

[0001] This utility model belongs to the field of navigation radar technology and relates to a marine navigation radar. Background Technology

[0002] Ships are man-made transportation vehicles that mainly operate in geographical waters. Radar is an important instrument on ships. Radar, also known as radio positioning, is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance, azimuth, and altitude, thus achieving positioning.

[0003] A radar navigation and positioning device, application number 202323094398.3, includes a base with a radar navigation and positioning device on its upper end. A radar navigator body is detachably installed within the radar navigation and positioning device, with its lower end resting on the upper end of the base. The radar navigation and positioning device includes a protective positioning component and a clamping component. This utility model discloses a radar navigation and positioning device where the lower end of the radar navigator body is interlocked with a mounting retaining ring and a limiting ring groove to prevent upward displacement of the radar navigator body during use. The device's ease of use is further enhanced by simple pulling for installation and clamping. Furthermore, the protective positioning component can be easily disassembled and installed for model replacement. The model of the protective positioning component can be changed according to the model of the installed radar navigator body, effectively enhancing the device's adaptability. Current navigation radars often require height adjustment based on the operating environment to improve their detection range and prevent collision damage in special terrains. However, the navigation radar in this application lacks height adjustment functionality. Therefore, designing a marine navigation radar to solve these problems is necessary. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-2 The specific embodiments of this utility model will be described in further detail.

[0017] In this embodiment, through Figure 1-2 As shown, this utility model includes a navigation radar 1, on which a plurality of mating blocks 2 are fixed. Each mating block 2 is hinged to a bracket assembly. Each bracket assembly is hinged to a connecting block 3. Each connecting block 3 is disposed on a placement frame. A drive adjustment assembly is fixed on the placement frame.

[0018] The position of the connecting block 3 is controlled by the drive adjustment component, thereby controlling the height of the bracket assembly and the height of the navigation radar 1, which facilitates the navigation radar 1 to increase its detection range.

[0019] In this embodiment, through Figure 1-2 As shown, the placement rack is composed of multiple long plates 4, which are equidistantly distributed in a circle. One end of each of the multiple long plates 4 is fixed together. Each of the multiple long plates 4 has a placement groove 5, which are interconnected. The drive adjustment component is disposed in the placement groove 5, and each of the connecting blocks 3 is slidably disposed in the placement groove 5.

[0020] There are three long plates 4, which are arranged in a triangular position to support the navigation radar 1, making the support more stable.

[0021] In this embodiment, through Figure 2 As shown, the bracket assembly includes a first support rod 6 hinged to the mating block 2, the end of the first support rod 6 away from the mating block 2 is fixed to a second support rod 8 by a shock absorber 7, and the end of the second support rod 8 away from the shock absorber 7 is hinged to the connecting block 3.

[0022] The position of the connecting block 3 can be controlled by the drive adjustment component, thereby controlling the height of the navigation radar 1;

[0023] When the three connecting blocks 3 move together toward the central axis of the placement frame, the angle between the second support rod 8, the shock absorber 7 and the first support rod 6 and the placement frame becomes larger and larger, and the navigation radar 1 rises higher and higher.

[0024] When the three connecting blocks 3 move together in opposite directions to the central axis of the placement frame, the angle between the second support rod 8, the shock absorber 7, and the first support rod 6 and the placement frame becomes smaller and smaller, and the position of the navigation radar 1 becomes lower. The height of the navigation radar 1 is controlled by controlling the position of the connecting blocks 3.

[0025] In this embodiment, through Figure 1-2 As shown, the drive adjustment assembly includes a motor 10 fixed at the center of the placement frame. A first bevel gear 9 is fixed at the output end of the motor 10. A plurality of second bevel gears 11 mesh with the first bevel gear 9.

The threaded rod 12 is connected to the second bevel gear 11.

[0026] The motor 10 drives the first bevel gear 9 to rotate, the first bevel gear 9 drives the second bevel gear 11 to rotate, the second bevel gear 11 drives the threaded rod 12 to rotate, thereby driving the connecting block 3 to move. By controlling the rotation direction of the motor 10, the movement direction of the connecting block 3 is controlled, and the height of the navigation radar 1 is controlled.

[0027] In this embodiment, through Figure 1-2 As shown, a rotating disk 18 is fixed on the upper side of the first bevel gear 9, and a handle 19 is fixed on the rotating disk;

[0028] When the motor 10 fails, the height of the navigation radar 1 can be adjusted by manually driving the handle 19 and the rotating disk 18 to drive the first bevel gear 9 to rotate, thus avoiding the inability to adjust the height of the navigation radar 1 when the motor 10 fails.

[0029] All the above rotating connections use bearings for rotating connections, and all sliding connections use grooves and rails for sliding connections.
