Description

Technical Field

[0001] This utility model relates to the field of navigation mark technology, specifically a navigation mark collision detection device. Background Technology

[0002] Navigational aids are navigational facilities that mark waterways and guide ships. The correct marking of navigational aids is an important guarantee for the safety of ship navigation and one of the main bases for guiding ships at night.

[0003] Maritime navigation lights are a type of navigation aid. With the development of the shipping industry, the density of ships in the region has increased rapidly. Due to reasons such as negligence by ship operators, accidents involving collisions between maritime navigation lights and passing ships occur frequently, and there are also cases of hit-and-run. On the one hand, damage to navigation lights is not easy to detect, and on the other hand, finding the perpetrator is also a very big problem.

[0004] Chinese Announcement No. CN219496672U discloses a navigation aid collision detection device. This device includes an attitude sensor and a main control unit. The attitude sensor transmits the navigation aid's rotation angle, tilt angle, and collision information to the main control unit. The main control unit is connected to a radar module, an AIS information collector, a camera, a power supply unit, and a wireless communication module. The radar module performs horizontal scanning using a 360-degree scanning radar, outputting 360-degree two-dimensional point cloud data. The AIS information collector receives maritime AIS signals and identifies specific vessel information. The camera collects image information around the navigation aid. The power supply unit provides operating voltage, and the wireless communication module transmits the collected data to the backend system. This invention utilizes advanced radar detection technology and video analysis technology, enabling effective all-weather real-time monitoring of areas and providing effective protection for the depth of key areas.

[0005] The above solution effectively achieves navigation mark collision detection through radar detection technology and video analysis technology. During this process, when a single camera is used to collect image information around the navigation mark, the navigation mark itself will obstruct the camera's acquisition area. Based on this, a navigation mark collision detection device is provided. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-4In this embodiment of the utility model, a navigation beacon collision detection device includes a navigation beacon assembly 1 composed of a float 101, a column cylinder 102, a connecting flange 103, a convex connecting joint 104, an I-shaped connecting joint 105, and a navigation beacon light 106. The float 101, column cylinder 102, connecting flange 103, convex connecting joint 104, I-shaped connecting joint 105, and navigation beacon light 106 are connected and fixed vertically in sequence. An image acquisition component 2 is provided on the top of the connecting flange 103 and the outside of the I-shaped connecting joint 105. The image acquisition component 2 is used to realize multi-directional image acquisition.

[0028] Image acquisition component 2 includes an acquisition unit and a driving unit;

[0029] The acquisition unit is used to acquire images, and the driving unit is used to realize the circular movement of the acquisition unit, thereby achieving unobstructed multi-directional image acquisition.

[0030] The acquisition unit includes a convex sleeve arm 201 and a 360-degree PTZ camera 202;

[0031] The convex sleeve arm 201 is sleeved on the outside of the I-shaped connecting section 105. The 360-degree PTZ camera 202 is installed at the bottom of the horizontal arm of the convex sleeve arm 201 through a bracket. The convex sleeve arm 201 provides suspension support and rotation support for the 360-degree PTZ camera 202.

[0032] The 360-degree PTZ camera 202 is used for image acquisition of the area facing one side of the column cylinder 102;

[0033] The drive unit includes a gear 205, a rotating shaft 206, and a drive motor 207;

[0034] The annular part of the convex sleeve arm 201 has a transmission cavity 203 that penetrates the bottom of the convex sleeve arm 201, and an annular tooth block 204 is fixed at the bottom of the inner wall of the inner ring of the transmission cavity 203.

[0035] Gears 205 are distributed inside the transmission cavity 203 and mesh with the ring tooth block 204. The rotating shaft 206 is fixed to the bottom end of gears 205 and passes through the bottom of the I-shaped connecting joint 105 to the inside of the convex connecting joint 104.

[0036] The drive motor 207 is mounted on the top of the connecting flange 103 and located inside the convex connecting joint 104. The top of the output end of the drive motor 207 is locked to the rotating shaft 206. The drive motor 207 drives the gear 205 to rotate, thereby realizing the circumferential rotation of the convex sleeve arm 201.

[0037] In this embodiment, it should be noted that when the navigation beacon component 1 is in use, the float 101 is equipped with corresponding solar panels and anti-collision guardrails to prevent the ship from colliding with or coming into contact with the solar panels, image acquisition component 2, and navigation beacon light 1036. The float 101 is equipped with a main control unit, power supply unit, attitude sensor, radar module, AIS information collector, positioning module, and wireless communication module to realize collision detection.

[0038] Meanwhile, during use, the image acquisition component 2 can acquire images of the surrounding area of ​​the navigation beacon component 1. At this time, the 360-degree PTZ camera 202 can be adjusted in multiple directions by its own rotation drive structure. Large-area angle image acquisition can be achieved when the convex sleeve arm 201 is not rotating. However, the column cylinder 102 will block the image acquisition area of ​​the 360-degree PTZ camera 202. At this time, the drive motor 207 can be started to drive the gear 205 to rotate. The gear 205 drives the convex sleeve arm 201 to rotate through the ring tooth block 204 that meshes with it, thereby realizing the circumferential operation of the 360-degree PTZ camera 202, thereby eliminating the blocking effect of the column cylinder 102 and realizing all-round image acquisition of the surrounding area.

[0039] It should also be noted that the set rotation angle of the convex sleeve arm 201 is less than 360 degrees, in order to avoid the connection lines of the 360-degree PTZ camera 202 from getting tangled.

[0040] Please refer to this carefully. Figures 1-4 Sealing elements are provided between the convex connecting joint 104 and the connecting flange 103, and between the bottom of the convex sleeve arm 201 and the bottom of the I-shaped connecting joint 105;

[0041] The connecting flange 103 has a through hole in the middle that is tangentially connected to the column cylinder 102 and the convex connecting joint 104. The I-shaped connecting joint 105 is connected to the inner cavity of the convex connecting joint 104, and the top of the I-shaped connecting joint 105 has a through hole for the power line of the navigation light 106 to pass through.

[0042] In this embodiment: This structure can maintain a good sealing effect in the area where the drive motor 207, gear 205 and annular tooth block 204 are located, and prevent the drive motor 207, gear 205 and annular tooth block 204 from being affected by external rainwater.
