Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices for underwater cameras, and in particular to a lifting device for underwater cameras. Background Technology

[0002] In today's era, as humanity's advance into the ocean accelerates, marine development is progressing at a rapid pace, underwater engineering construction is in full swing, and marine scientific research is deepening. Looking back, early underwater operations were extremely primitive, mainly relying on divers carrying oxygen tanks and holding simple camera equipment to dive into the water. However, this method had many drawbacks. Divers were limited by the capacity of their oxygen tanks, which restricted their working time. They frequently had to travel between the surface and underwater, resulting in low efficiency and physical strain. At the same time, the human body has a narrow field of vision and is clumsy underwater, making it difficult to cope with the harsh conditions such as high pressure and strong currents in the deep sea. In complex environments, it is impossible to delve deep enough to collect accurate and complete information. Subsequently, fixed underwater cameras emerged. Although they can record continuously, their fixed locations result in a narrow monitoring range. When facing large areas of water and dynamically changing targets, adjusting the viewing angle is difficult. In view of this, underwater camera lifting devices have emerged. They draw on land lifting technology and are optimized for underwater characteristics. They strive to take on the heavy responsibility of diverse underwater operations and monitoring with flexible position and angle adjustment, empowering many tasks such as subsea pipeline flaw detection, marine biological research, and underwater archaeological exploration.

[0003] In existing devices, the lifting device lacks precision in controlling the camera angle, making it difficult to accurately capture images from specific positions and angles. The angle adjustment mechanism is not flexible or precise enough, resulting in blind spots and failing to meet the need for multi-angle shooting of specific targets or scenes. Utility Model Content

Gear 1 is rotatably connected between the two threaded screws. Gear 1 and the threads around the threaded screws mesh with each other. The rotating shaft is fixedly connected to the inside of gear 1, and the rotating shaft is movably connected to the inner top surface of the protective shell.

[0010] As a further embodiment of this utility model: the limiting rod is fixedly connected to the inner walls of the front and rear sides of the protective shell, the moving block is slidably connected to the two limiting rods around the perimeter, the limiting frame is fixedly connected to the bottom of the moving block, the toothed block moving frame is movably connected to the inside of the limiting frame, and the rotating shaft passes through the moving block and the limiting frame.

[0013] As a further embodiment of this utility model: the movable column is fixedly connected to the bottom of the electric push rod, the rotating bearing is fixedly connected to the inside of the protective shell, the rotating cylinder is fixedly connected to the bottom of the rotating bearing, and the movable column is movably connected to the inside of the rotating bearing and the rotating cylinder, and the rotating cylinder has oblique openings around its perimeter.

[0014] As a further embodiment of this utility model: the movable rod is fixedly connected to one side of the moving column, and the movable rod passes through the moving column.

The inner wall of the protective shell has two grooves, and both ends of the movable rod are movably connected to the grooves in the inner wall of the protective shell.

[0015] Compared with the prior art, the present invention provides a lifting device for an underwater camera, which has the following advantages:

[0016] 1. This underwater camera hoisting device uses a vessel to remain on the water surface. A controller extends and retracts an electric telescopic boom, lowering the camera below the water surface. The controller then controls a moving mechanism and a turning mechanism, allowing the camera to move flexibly and rotate 360 ​​degrees within a plane for better underwater imaging. This device improves shooting accuracy and efficiency, allows for rapid adjustment of the camera's position and angle, accurately captures target images, avoids repeated equipment adjustments, adapts to different terrains, and meets diverse mission requirements.

[0017] 2. This underwater camera lifting device uses a controller to control two rotary motors, which in turn rotate two threaded screws. When the two threaded screws rotate in the same direction, they push gear one and the rotating shaft, causing the moving block and the limiting frame to move to one side. When the two threaded screws rotate in opposite directions, gear one rotates around the rotating shaft, which in turn drives gear two. Gear two then drives the inner toothed block of the toothed block moving frame, allowing the toothed block moving frame to move laterally. This, in turn, moves the connecting plate and the electric telescopic rod. Thus, it can move flexibly within a plane, allowing the camera to quickly align with different parts of the target object or scene. The position and angle can be quickly adjusted according to shooting needs, eliminating the need for frequent adjustments to the entire device or rearrangement, reducing operating time and labor costs, and improving work efficiency.

[0018] 3. This underwater camera lifting device uses a controller to control the extension and retraction of an electric push rod, which pushes a moving column. The moving column drives a movable rod to move downwards. The movable rod moves within openings on both sides of a rotating cylinder and applies force obliquely to the openings of the rotating cylinder. The rotating bearing rotates, thereby causing the rotating cylinder to rotate and driving the camera to rotate. As a result, the camera can observe the underwater environment without blind spots. By flexibly adjusting the direction of the camera, some of the effects of shaking can be offset, keeping the image relatively stable, improving the quality of images and videos, and better adapting to complex underwater environments.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0030] A lifting device for an underwater camera, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the device includes a protective outer shell 3. A moving mechanism 4 is fixedly connected inside the protective outer shell 3, and the protective outer shell 3 is movably connected to the bottom and top of the moving mechanism 4. An electric telescopic rod 5 is fixedly connected to the bottom of the moving mechanism 4, and a steering mechanism 6 is fixedly connected to the bottom of the electric telescopic rod 5. A camera 7 is fixedly connected to the bottom of the steering mechanism 6. Support plates 2 are fixedly connected to both sides of the protective outer shell 3. A controller 1 is fixedly connected to one side of the support plate 2. A hull 8 is fixedly connected to the bottom of the two support plates 2. The controller 1 is model KMDA-3303, and the electric telescopic rod 5 is model DTZ5000-1200-37.

[0031] During operation, the device remains on the water surface via the hull 8. The controller 1 controls the extension and retraction of the electric telescopic rod 5, lowering the camera 7 below the water surface. Then, the controller 1 controls the moving mechanism 4 and the steering mechanism 6, enabling the camera 7 to move flexibly and rotate 360 ​​degrees within a plane for better underwater filming. As a result, the device improves the accuracy and efficiency of filming, allows for quick adjustment of the camera position and angle, accurately captures target images, avoids repeated equipment adjustments, adapts to different terrains, and meets diverse mission requirements.

[0032] To ensure that camera 7 can move within a certain range, such as Figure 2 , Figure 3 and Figure 4 As shown, the moving mechanism 4 includes a threaded screw 401, a first gear 402, a rotating shaft 403, a rotary motor 404, a limiting plate 405, a limiting rod 406, a moving block 407, a toothed block moving frame 408, a connecting plate 409, a limiting frame 410, and a second gear 411. The rotary motor 404 is fixedly connected to the inner wall of the protective shell 3, and the threaded screw 401 is fixedly connected to one side of the rotary motor 404.

[0033] The limiting plate 405 is fixedly connected to the circumference of the threaded screw 401 and is also fixedly connected to the inner top surface of the protective shell 3. The gear 402 is rotatably connected between the two threaded screws 401. The threads of the gear 402 and the threaded screw 401 mesh with each other. The rotating shaft 403 is fixedly connected to the inside of the gear 402 and is movably connected to the inner top surface of the protective shell 3.

[0034] The limiting rod 406 is fixedly connected to the inner walls of the front and rear sides of the protective shell 3. The moving block 407 is slidably connected to the two limiting rods 406 around the perimeter. The limiting frame 410 is fixedly connected to the bottom of the moving block 407. The toothed block moving frame 408 is movably connected to the inside of the limiting frame 410, and the rotating shaft 403 passes through the moving block 407 and the limiting frame 410.

[0035] Gear 2 411 is fixedly connected to the bottom of the rotating shaft 403 and is movably connected to the inside of the tooth block moving frame 408. Gear 2 411 meshes with the tooth block inside the tooth block moving frame 408. Connecting plate 409 is fixedly connected to the bottom of the tooth block moving frame 408.

[0036] During operation, the controller 1 controls two rotary motors 404 to rotate two threaded screws 401. When the two threaded screws 401 rotate in the same direction, they push gear 1 402 and rotating shaft 403, causing the moving block 407 and limit frame 410 to move to one side. When the two threaded screws 401 rotate in opposite directions, gear 1 402 rotates around rotating shaft 403. Rotating shaft 403 drives gear 2 411, which in turn drives the inner toothed block of toothed block moving frame 408, allowing toothed block moving frame 408 to move laterally. This, in turn, moves connecting plate 409 and electric telescopic rod 5. Thus, it can move flexibly in a plane, allowing the camera to quickly aim at different parts of the target object or scene. The position and angle can be quickly adjusted according to shooting needs, eliminating the need for frequent adjustments to the entire equipment or rearrangement, reducing operating time and labor costs, and improving work efficiency.

[0037] To ensure that camera 7 can capture more comprehensive angles when shooting underwater, such as Figure 5 and Figure 6 As shown, the steering mechanism 6 includes a protective shell 601, an electric push rod 602, a rotating cylinder 603, a movable rod 604, a moving column 605, and a rotating bearing 606. The electric push rod 602 is fixedly connected to the bottom of the electric telescopic rod 5, the protective shell 601 is fixedly connected to the bottom of the electric telescopic rod 5, and the electric push rod 602 is movably connected inside the protective shell 601.

[0038] The movable column 605 is fixedly connected to the bottom of the electric push rod 602, the rotating bearing 606 is fixedly connected to the inside of the protective shell 601, the rotating cylinder 603 is fixedly connected to the bottom of the rotating bearing 606, and the movable column 605 is movably connected to the inside of the rotating bearing 606 and the rotating cylinder 603, and the rotating cylinder 603 has oblique openings around its perimeter.

[0039] The movable rod 604 is fixedly connected to one side of the moving column 605, and the movable rod 604 passes through the moving column 605. Both ends of the movable rod 604 are movably connected to the opening in the rotating cylinder 603. The inner wall of the protective shell 601 has two grooves. Both ends of the movable rod 604 are movably connected to the grooves in the inner wall of the protective shell 601. The electric push rod 602 is model JAL41.

[0040] During operation, the controller 1 controls the extension and retraction of the electric push rod 602, which pushes the moving column 605. The moving column 605 drives the movable rod 604 to move downward. The movable rod 604 moves within the openings on both sides of the rotating cylinder 603 and applies force obliquely to the openings of the rotating cylinder 603. The rotating bearing 606 rotates, thereby causing the rotating cylinder 603 to drive the camera 7 to rotate. As a result, the camera 7 can observe the underwater environment without blind spots. By flexibly adjusting the direction of the camera, some of the shaking effects can be offset, keeping the image relatively stable, improving the quality of images and videos, and better adapting to complex underwater environments.

[0041] Working principle: The hull 8 remains on the water surface. The controller 1 controls the extension and retraction of the electric telescopic rod 5, causing the camera 7 to descend below the water surface. Then, the controller 1 controls two rotary motors 404, causing two threaded screws 401 to rotate. When the two threaded screws 401 rotate in the same direction, they push gear 1 402 and rotating shaft 403, causing the moving block 407 and limit frame 410 to move to one side. When the two threaded screws 401 rotate in opposite directions, gear 1 402 rotates around rotating shaft 403. Rotating shaft 403 drives gear 2 411, which in turn drives the inner toothed block of the toothed block moving frame 408, allowing the toothed block moving frame 408 to move laterally. This, in turn, moves the connecting plate 409 and the electric telescopic rod 5.

[0042] Finally, the controller 1 controls the extension and retraction of the electric push rod 602, which pushes the moving column 605. The moving column 605 drives the movable rod 604 to move downward. The movable rod 604 moves in the openings on both sides of the rotating cylinder 603 and applies force obliquely to the openings of the rotating cylinder 603. The rotating bearing 606 rotates, thereby causing the rotating cylinder 603 to drive the camera 7 to rotate, so as to better capture the underwater situation.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
