Description

Technical Field

[0001] This invention relates to the field of underwater sampling technology, specifically to a rapid-diving seabed sampling robot. Background Technology

[0002] Ocean currents are like 'rivers' in the ocean. Although seawater is constantly moving, not all seawater flows at the same speed. Instead, the flow is concentrated in certain narrow sea areas where the speed is greater, forming ocean currents. This is somewhat similar to rivers on land. 。 Australian and Japanese scientists have discovered a fast-flowing deep-sea current near Antarctica, with a flow rate equivalent to 40 Amazon Rivers. This current will help researchers monitor the impacts of climate change on the global oceans.

[0003] Ocean currents carry organisms and microorganisms from all over the world. In order to detect the range and flow sequence of an ocean current, water samples are often collected from a section of the current. By analyzing the microorganisms in the water, it is possible to trace where the current came from and thus determine the path of the current.

[0004] Currently, underwater exploration robots must control the impact of underwater pressure and overcome the resistance from water flow. To facilitate data collection, these robots are often irregularly shaped. The more irregular the shape, the greater the resistance from water flow during descent. Since ocean currents are very fast, they often miss the calculated current range, making experiments impossible. Summary of the Invention

This solves the problem that current underwater exploration robots must control underwater pressure and overcome water resistance. Furthermore, current robots, designed for easier sampling, are often irregularly shaped. The more irregular the shape, the greater the water resistance during descent.

[0026] Preferably, the first drive rack is meshed with the first drive tooth, and the second drive rack is meshed with the second drive tooth.

[0027] This invention provides a rapid-diving seabed sampling robot. It has the following beneficial effects:

[0028] This solution addresses the challenges of current underwater exploration robots, which, as described in the background, must overcome both underwater pressure and water flow resistance. To facilitate data collection, these robots are often irregularly shaped, leading to increased resistance during descent. Given the high velocity of ocean currents, these robots frequently miss the calculated current range, hindering experiments. This invention, however, utilizes a streamlined robot main unit and front-end design to significantly reduce underwater resistance. The robot's wireless remote control module controls all components, and its sensors detect depth, temperature, and water flow speed. Furthermore, the rear-end directional control component regulates the robot's direction. A front-end searchlight illuminates the path, and the data collection and propulsion components collect data from the target water area, including image acquisition, water sample collection, and microbial collection.

[0029] The system uses panoramic cameras in various acquisition and propulsion components to capture images, which are then stitched together to form a panoramic view. Before reaching the target sea area, the lifting base at the top is pushed by a lifting electric push rod, causing the streamlined top cover to cover the acquisition port, minimizing the contact between the acquisition plate and the flowing water. When the target sea area is reached, the cover is opened, and water is poured into the acquisition tank in the acquisition plate. The water then passes through the gaps in the filter floss rubber strips, where the filter floss traps the plankton floating in the water. After the acquisition is completed, the cover is closed again. The electric turbine can be activated to accelerate the descent speed. Even when the streamlined top cover is raised, water can still be drawn in and pushed back through the propulsion inlet.

[0030] Specifically, the first and second drive electric actuators in the directional control assembly drive the first and second drive racks at the front end, respectively, to mesh with the first and second drive teeth at the front end. This drives the steel cable connecting posts at the outer ends of the first and second drive bars to pull their respective control steel cables, thereby causing the main tail fin at the rear end to deflect. The first and second directional tail fins on the tail fin guide the water flow, thus achieving the function of steering adjustment. Attached Figure Description

[0063] Working principle:

[0064] The present invention can greatly reduce the resistance of the robot moving in water by using the streamlined shape of the robot host 1 and the front end. The wireless remote control module in the robot host 1 can control various components, and the various sensors in it can detect depth, temperature and water flow speed. It can also control the direction control component 3 at the rear end to control the direction of the robot's movement. The searchlight 5 at the front end provides light for the line of sight in front, and the collection and propulsion component 2 collects data on the target water area, including image acquisition, water sample collection and microbial collection.

[0065] The panoramic camera 205 in the acquisition and propulsion component 2 collects images from all directions, which can be stitched into a panoramic view. Before reaching the target sea area, the lifting base 2024 at the top is pushed by the lifting electric push rod 2025, so that the streamlined top cover 2023 covers the acquisition hole 203, minimizing the contact between the acquisition plate 204 and the external flowing water. When the target sea area is reached, the plate will open and water will be poured into the acquisition tank 2042 in the acquisition plate 204. The water will then pass through the gaps in the filter floss rubber strip 2043 and the filter floss 2044 will retain the plankton floating in the water. After the collection is completed, the plate will close again. The electric turbine 2064 can be activated to accelerate the descent speed. Even when the streamlined top cover 2023 is raised, water can still be drawn in and pushed back by the propulsion inlet hole 2062.

[0066] Specifically, the first drive electric actuator 30125 and the second drive electric actuator 30126 in the directional control component 3 drive the first drive rack 30123 and the second drive rack 30124 at the front end, respectively meshing with the first drive tooth 30137 and the second drive tooth 30138 at the front end. This drives the steel cable connecting post 3014 at the outer end of the first drive bar 30135 and the second drive bar 30136 to pull their respective control steel cables 3015, thereby causing the main tail fin 6 at the rear end to deflect. The water flow is guided by the first directional tail fin 7 and the second directional tail fin 8 on it, thereby achieving the function of steering adjustment.
