Description

Technical Field

[0001] The utility model relates to the technical field of ship detection equipment, in particular to a multi-angle adjustable ship target visual detection device. Background Art

[0002] With the increasing frequency of marine resource development, maritime transportation, and maritime safety supervision, ship target visual detection technology plays a key role in ensuring maritime operational safety, maintaining maritime order, and improving transportation efficiency. Ship target visual detection can monitor and assist in the management of maritime traffic and transportation; in marine monitoring, it has a strong supervisory effect on fishery dumping and illegal smuggling; and in navigation safety, it can determine whether there are abnormal navigation behaviors such as landings and stagnation, thereby ensuring coastal and maritime safety.

[0003] In the related art, existing methods for visual detection of ship targets generally utilize optical photography and infrared imaging to acquire visual and infrared images as image data for real-time identification and detection of target ships at sea. However, existing image acquisition and detection devices are often fixed at specific locations on the ship due to limitations on ship specifications and types, and can only perform detection within a fixed angle range. In order to ensure detection results, a large number of detection devices are often required to ensure range and accuracy. Detection devices in some locations may also face complex and changing marine environments, such as light reflections on the water surface, interference from buildings and plants on the sea and shore, resulting in target occlusion and pixel occupancy, leading to reduced detection accuracy.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the three-dimensional structure of one side of the multi-angle adjustable ship target visual detection device provided by an embodiment of the present utility model; Figure 2 This is a schematic diagram of the three-dimensional structure of the other side of the multi-angle adjustable ship target visual detection device provided by an embodiment of the present utility model; Figure 3 This is a partial structural diagram of the other side of the multi-angle adjustable ship target visual detection device provided by an embodiment of the present utility model; Figure 4 This is a cross-sectional view of the structure inside the chassis provided by an embodiment of the utility model; Figure 5 This is a cross-sectional view of the structure of the telescopic mechanism provided by the embodiment of the present utility model. Figures 1 to 5 As shown, an embodiment of the present invention provides a multi-angle adjustable ship target visual detection device, including: a mounting bracket 1 and a detection component 2.

[0026] The mounting bracket 1 includes a base plate 11, a telescopic mechanism 12, a motorized turntable 13, and a chassis 14. The motorized turntable 13 is connected to the base plate 11 via the telescopic mechanism 12 and is configured to be raised and lowered relative to the base plate 11 via the telescopic mechanism 12. The motorized turntable 13 includes a rotating end perpendicular to the base plate 11, and the chassis 14 is connected to the rotating end. The chassis 14 is rotatably connected to a rotational shaft 141 parallel to the base plate 11, and an angle adjustment mechanism 142 is drivingly connected to the rotational shaft 141. The ends of the rotational shaft 141 extend through the sides of the chassis 14.

[0027] The detection component 2 includes a camera 21 and an infrared thermal imager 22. The camera 21 and the infrared thermal imager 22 are connected to both ends of the rotating shaft 141 respectively.

[0028] In the embodiment of the present utility model, the multi-angle adjustable visual detection device for ship targets is fixedly installed at a relevant fixed position of the ship through the base plate 11. When it is working, various devices on its telescopic mechanism 12, electric turntable 13 and chassis 14, as well as the detection component 2, are all stably electrically connected to the outside, realizing uninterrupted transmission of signals and power. Among them, when the detection component 2 is working, the camera 21 arranged at one end of the rotating shaft 141 is used to obtain clear images when the light is sufficient, and the infrared thermal imager 22 arranged at the other end of the rotating shaft 141 is used to identify targets by detecting thermal radiation at night or in bad weather, reducing external environmental interference and improving detection accuracy. At the same time, by setting the telescopic mechanism 12, the detection component 2 can follow the chassis 14 and the electric turntable 13 to adjust the height relative to the installation position of the base plate 11 under the drive of the telescopic mechanism 12. By using the rotating end of the electric turntable 13 to rotate, the chassis 14 can be driven to rotate horizontally relative to the base plate 11, so as to provide the detection angle adjustment freedom in the horizontal direction for the camera 21 and the infrared thermal imager 22, realizing 360-degree circumferential detection and quickly capturing ship targets in different directions. Further, by driving the rotating shaft 141 to rotate through the relevant drive mechanism in the chassis 14, the camera 21 and the infrared thermal imager 22 can be adjusted in the pitching direction, further increasing the recognition and detection range of the multi-angle adjustable visual detection device for ship targets set at a single position, effectively solving the technical problems of large detection limitations and low detection accuracy caused by the defects of the structure and facility position limitations of the existing target visual detection device in the related technology.

[0029] Optionally, the camera 21 and the infrared thermal imager 22 are respectively rotatably connected to both ends of the rotating shaft 141. Exemplarily, in a possible implementation manner of the embodiment of the present utility model, the camera 21 and the infrared thermal imager 22 are respectively fixedly connected to both ends of the rotating shaft 141. The camera 21 and the infrared thermal imager 22 have the same orientation when working, and synchronously rotate under the drive of the rotating shaft 141 to realize the adjustment of the pitching angle, realizing double detection of targets in the same orientation. In another possible implementation manner, the camera 21 and the infrared thermal imager 22 can be respectively rotatably connected to both ends of the rotating shaft 141 by adding components such as rotating motors. That is, under the control of an external signal, the camera 21 and the infrared thermal imager 22 can respectively rotate axially relative to the rotating shaft 141, realizing separate rotation control in the pitching direction, so as to respectively detect the same or different targets at different pitching angles by using the camera 21 and the infrared thermal imager 22, further increasing the detection range.

[0030] Optionally, a slip ring 3 is mounted on the top of the electric turntable 13, and the camera 21 and the infrared thermal imager 22 are electrically connected to the rotating ends of the slip ring 3. For example, in this novel embodiment, the slip ring 3 is mounted on the top of the electric turntable 13 to ensure that the electrical connection between the equipment on the chassis 14 and the outside is stable during the rotation of the electric turntable 13, thereby achieving uninterrupted transmission of signals and power.

[0031] Optionally, the angle adjustment mechanism 142 includes a transmission shaft 1421 and a first motor 1422. The transmission shaft 1421 is rotatably disposed in the chassis 14. A worm 1423 is mounted on the side wall of the transmission shaft 1421. A turbine 1411 is mounted on the side wall of the rotating shaft 141. The worm 1423 cooperates with the turbine 1411. The first motor 1422 is disposed on the chassis 14 and is in transmission connection with the transmission shaft 1421. For example, in an embodiment of the present utility model, when the angle adjustment mechanism located in the chassis 14 is in operation, it first receives a control signal from an external device through the first motor 1422, drives the transmission shaft 1421 to rotate, and then drives the rotating shaft 141 to rotate through the meshing relationship between the turbine 1411 and the worm 1423, thereby ultimately achieving pitch angle adjustment of the camera 21 and the infrared thermal imager 22. At the same time, the worm 1423 and the turbine 1411 are used for transmission cooperation. When they engage with each other, the transmission shaft 1421 stops rotating at the output end of the first motor 1422, and the turbine 1411 and the rotating shaft 141 can be self-locked to avoid relative rotation and shaking under external influences, thereby ensuring the detection stability after fixing the direction.

[0032] Optionally, the telescopic mechanism 12 includes a sleeve column 121, a telescopic column 122, a threaded rod 123, and a second motor 124. One end of the sleeve column 121 is vertically connected to the base plate 11. The telescopic column 122 is telescopically installed at the other end of the sleeve column 121.

The threaded rod 123 is rotatably arranged inside the sleeve column 121 and one end thereof is threadedly connected to the threaded hole 1221. The second motor 124 is arranged on the sleeve column 121 and its output end extends into the sleeve column 121. The output ends of the sleeve column 121 and the other end of the threaded rod 123 are both provided with bevel gears 125 and are meshed with each other. Exemplarily, in the embodiment of the present invention, the telescopic mechanism 12 is integrally in a nested longitudinal telescopic rod structure. When it works, the second motor 124 at the bottom receives a control signal from an external device, and uses the meshing structure of its driving end and the bevel gear 125 at the bottom of the threaded rod 123 to achieve power transmission and drive the threaded rod 123 to rotate. The threaded rod 123 is rotatably arranged inside the sleeve column 121 through a cage 126, and the top end of the telescopic column 122 extends into the threaded hole 1221 of the telescopic column 122 and is matched with the internal thread. The outer side wall of the telescopic column 122 is matched with the inner hole of the sleeve column 121, forming a kinematic pair structure in which the telescopic column 122 is lifted and extended and lowered and retracted under the drive of the threaded rod 123 and the axial limit of the sleeve column 121, so as to realize the height adjustment of the upper electric turntable 13, the chassis 14, and the detection component 2.

[0033] Optionally, baffles 4 are provided at the tops of both the camera 21 and the infrared thermal imager 22. A support frame 41 is provided on one side of the baffle 4 and is fixedly connected to the rotating shaft 141 through the support frame 41. Exemplarily, in the embodiment of the present invention, a rod-shaped support frame 41 is fixedly sleeved on the shafts of the rotating shaft 141 extending out of both sides of the chassis 14, and is respectively extended above the camera 21 and the infrared thermal imager 22, and is connected to cover the baffles 4 at the tops of the camera 21 and the infrared thermal imager 22. Under the connection of the support frame 41, the baffle 4 can rotate synchronously with the rotating shaft 141 and the lower camera 21 and infrared thermal imager 22, and can block part of the rainwater and direct sunlight during the operation of the camera 21 and the infrared thermal imager 22, reduce the influence of environmental factors on the equipment detection, and improve the service life and detection accuracy of the equipment.

[0034] Optionally, the multi-angle adjustable visual detection device for ship targets further includes a control panel 5, which is arranged on the telescopic mechanism 12. The telescopic mechanism 12, the electric turntable 13, the chassis 14, the camera 21, and the infrared thermal imager 22 are all communicatively connected to the control panel 5. Exemplarily, in the embodiment of the present invention, by installing an additional control panel 5 on the outer side wall of the sleeve column 121 of the telescopic mechanism 12, on-site control of the device is realized, and the convenience of product use is increased. Wireless signal transceivers are installed on both sides of the control panel 5 to realize data transmission and remote control between the device and the ship monitoring center or other devices, facilitating the operator to remotely and real-time obtain detection data and improving the practicality.

[0035] Optionally, a plurality of mounting holes 111 are provided on the base plate 11, and the plurality of mounting holes 111 are arranged in an array around the telescopic mechanism 12. Exemplarily, in the embodiment of the present invention, 4 mounting holes 111 are provided on the rectangular base plate 11, which are arranged in a rectangular array at the four corners of the base plate 11. By screwing in bolts, the fixed connection between the entire multi-angle adjustable visual detection device for ship targets and the relevant position of the ship can be realized.
