Description

TECHNICAL FIELD

[0001] The utility model relates to a monitoring device, in particular to a marine automatic obstacle avoidance adjustable image monitoring device. BACKGROUND

[0002] When a ship is berthing or entering narrow water area, the distance between the ship and other objects needs to be observed, which is usually observed by the crew or a camera, and then the ship driver is reminded to avoid collision. The camera for observing the ship fender condition is usually installed within the chord to avoid collision with other objects, which also causes the camera to have a certain visual dead angle. The crew needs to report the distance between the fender and other objects to the driver when the ship is berthing or driving in narrow water area. If the camera installation position exceeds the fender, a more comprehensive visual angle can be obtained, but collision with other ships or objects may occur. There are installation supports that can adjust the camera position on the market, but most of them have complex structure and need to be manually controlled. SUMMARY

[0022] As Figures 1-4As shown, a marine automatic obstacle avoidance adjustable image monitoring device includes a fixed bracket 1, which consists of a connecting plate and a mounting plate. The connecting plate is vertical and fixed to a wall with screws; the mounting plate is fixed to the connecting plate and extends horizontally. A motor 3 is mounted on the mounting plate of the fixed bracket 1 with screws. The output end of the motor 3 is connected to a lead screw 6. A lead screw nut 5 is threadedly connected to the lead screw 6. The lower end of the lead screw nut 5 slides against a track on the fixed bracket 1, and the upper end of the lead screw nut 5 is fixed to a telescopic bracket 2 with screws. When the motor 3 drives the lead screw 6 to rotate, the lead screw nut 5 moves left and right, thereby allowing the telescopic bracket 2 to move back and forth along the axis of the lead screw 6, achieving telescopic movement.

[0023] The obstacle detection sensor 9 is mounted on the servo motor 8, which is mounted on the upper end of the telescopic bracket 2. The camera 10 is mounted on the lower end of the telescopic bracket 2. The obstacle detection sensor 9 is an ultrasonic sensor, model number RU40U-M12-AP6X2-H1141. Ultrasonic sensors are characterized by high sensitivity, strong penetration, immunity to light and color effects, high measurement accuracy, and strong anti-interference capabilities. They can operate stably in dark environments, are unaffected by the color or transparency of the measured object, and can operate stably in dusty, dirty, or high-humidity environments, making them suitable for outdoor environments.

[0024] Camera 10 is independently controlled, and its control circuit is connected to the control room.

[0025] The obstacle detection sensor 9 is electrically connected to the controller. When the obstacle detection sensor 9 detects an obstacle, the controller controls the motor 3 to reverse and the telescopic bracket 2 to retract until the obstacle detection signal disappears or the limit device is reached and rotation stops. When there is no obstacle detection signal, the motor 3 rotates forward and the telescopic bracket 2 extends until an obstacle detection signal is generated or the limit device is reached and rotation stops.

[0026] The servo motor 8 is independently controlled, and its built-in controller adjusts the rotation angle and period T of the obstacle detection sensor 9. The servo motor 8 can adjust the detection angle of the obstacle detection sensor 9, enabling the obstacle detection sensor 9 to detect obstacles around the telescopic support 2.

[0027] The aforementioned motor 3, servo motor 8, and obstacle detection sensor 9 are powered by batteries.

[0028] Preferably, a retraction limiting member 4 and an extension limiting member 7 are fixed on the mounting plate of the fixed bracket 1 at both ends of the lead screw 6, respectively. The retraction limiting member 4 and the extension limiting member 7 limit the lead screw nut 5 when it retracts into place and extends into place. The retraction limiting member 4 and the extension limiting member 7 can be plate-shaped, block-shaped or other limiting structures.

[0029] Preferably, the mounting plate of the fixed support 1 is provided with a protective cover 11 fixed by screws, which can prevent foreign matters from falling into the running track of the screw nut 5 and causing blockage.

[0030] Working principle and process:

[0031] When the obstacle detection sensor 9 does not detect obstacles, the motor 3 drives the telescopic support 2 to extend forward, and the camera can obtain a better visual angle and eliminate the visual blind area. When the obstacle detection sensor 9 detects obstacles, the motor 3 reverses to drive the telescopic support 2 to retract backward, stops after running a rudder rotation cycle, and the obstacle detection sensor 9 detects signals again. If obstacles are detected again, continue to retract until the signals disappear or the retracting limit piece 4 is triggered, to avoid collision between the camera, the support and the obstacles.
