Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea exploration equipment, and in particular to a seabed sampling booster device and an observation system. Background Art

[0002] Deep-sea sampling grabs are one of the most important tools for deep-sea sampling and environmental surveys of mineral resources in my country, including polymetallic nodules, cobalt-rich crusts, hydrothermal sulfides, natural gas hydrates, and seafloor rare earth minerals. However, similar sampling equipment used in my country's early ocean resource and environmental surveys was primarily imported. Over the past decade, despite the upgrading of deep-sea sampling grabs and the maturation of various technical specifications, the rapid development of science and technology, both domestically and internationally, has placed higher demands on deep-water sampling equipment for long-term, high-efficiency, and high-stability deep-water operations. This has led to more refined, standardized, and scientifically designed deep-water sampling equipment to enhance the reliability, practicality, and stability of sampling in complex terrain mining areas.

[0003] Chinese invention patent publication number CN108680379B discloses a deep-sea omnidirectional mobile video grab, comprising a frame, a propulsion mechanism, an ultra-short baseline positioning mechanism, a three-point laser ranging mechanism, an underwater power supply mechanism, a sampling bucket, a whole-machine control mechanism, a hydraulic mechanism, and a camera mechanism. The frame comprises an upper frame and a lower frame, which are detachably connected, and the propulsion mechanism includes four thrusters. The present invention utilizes the propulsion mechanism, ultra-short baseline positioning mechanism, and three-point laser ranging mechanism to accurately position the device underwater. Based on the calculated height above the ground and sample size, the four thrusters cooperate to achieve 360° horizontal movement in any direction.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the existing deep-sea sampling grab uses a propeller propulsion device, which easily causes cavitation effect in the propulsion mechanism. The cavitation bubbles spread into the water, which easily affects the imaging quality of the camera mechanism and causes unclear camera shooting; therefore, a seabed sampling booster device and observation system are proposed. Summary of the Invention

[0005] In order to solve the technical problem that a deep-sea sampling grab uses a propeller propulsion device, which leads to cavitation effect at the propulsion mechanism, and the cavitation bubbles are scattered into the water, which easily affects the imaging quality of the camera mechanism and causes unclear camera shooting, the present invention provides a seabed sampling booster device and observation system.

[0006] The present invention is implemented by the following technical solutions: a submarine sampling booster device and observation system, comprising: a sampling rack, a mounting platform and a plurality of supporting platforms fixed to the inner wall of the sampling rack, and a grab bucket installed inside the sampling rack;

[0007] The photographic assembly includes a rotating chamber, a camera, and a first motor. The first motor is mounted on the bottom surface of the mounting platform. The rotating chamber is mounted on the upper surface of the mounting platform, and the output end of the first motor is connected to the bottom surface of the rotating chamber. The camera is mounted in the rotating chamber. An observation window is provided on the periphery of the rotating chamber.

[0008] The booster assembly includes several assembly frames, a water pump, an adjustment assembly and a pipeline assembly. The assembly frame is installed on the bottom surface of the support platform, the water pump is rotatably installed on the inner wall of the assembly frame, and the adjustment assembly is installed on the side wall of the assembly frame. The adjustment assembly adjusts the output angle of the water pump, and a guide nozzle is installed at the output end of the water pump;

[0009] The pipeline assembly is installed under the mounting platform. The pipeline assembly includes a connecting pipe, a water inlet pipe and a connecting pipe. The connecting pipe is a "mouth"-shaped pipe. The connecting pipe is hoisted under the mounting platform. Connecting pipes are connected between the connecting pipe and multiple groups of water pumps. The water inlet pipe is installed on the side of the connecting pipe, and the position of the water inlet of the water inlet pipe is suitable for the observation window.

[0010] Through the above technical solution, by setting multiple groups of water pumps as booster components, the water pumps obtain speed and then spray out through the nozzle. The reaction force of the resultant force of the sprayed water flow is thrust, which drives the sampling frame to move. When the ocean current or wind and waves cause the sampling device to shift in position, the position balance of the device is quickly restored; the booster component uses a water pump as a power source, which has many advantages, such as low noise, good concealment, and low blank effect; at the same time, during the water intake process of the booster component, a large amount of water flows into the connecting pipe through the water inlet pipe and is then output from the water pump. Therefore, when a large amount of water flows into the water inlet pipe, it will flush the outer wall of the observation window and quickly flush the observation window. When foreign matter appears in the observation window, the observation window can be quickly cleaned by the operation of the water pump, which greatly ensures that the camera can operate clearly and improves the shooting clarity.

[0011] As a further improvement of the above solution, a water inlet cover is installed at the water inlet end of the water inlet pipe.

[0012] As a further improvement of the above scheme, the adjustment component includes a drive frame, a second motor and a rotating belt. The drive frame is placed on the upper surface of the support platform and is located on one side of the support frame. The second motor is installed in the drive frame. A drive groove is opened on the inner wall of the assembly frame. The output end of the second motor is connected to the driving shaft, and the driving shaft is connected to the inside of the driving groove. The connecting shaft between the water pump and the support frame is the driven shaft, and the driven shaft is also connected to the driving groove. A first turntable is installed on the circumference of the driving shaft, and a second turntable is installed on the circumference of the driven shaft. A rotating belt is installed between the first turntable and the second turntable.

[0013] Through the above technical solution, the second motor drives the driving shaft to rotate, the driving shaft drives the first turntable to rotate, and the first turntable drives the driven shaft to rotate through the rotating belt, thereby changing the horizontal output angle of the water pump and the guide nozzle; since the four groups of water pumps are set in four directions, the multi-directional displacement of the device can be achieved by independently controlling the water pumps.

[0014] As a further improvement of the above solution, assembly frames are fixedly installed on both the front and rear end surfaces of the sampling rack, the two groups of grab buckets are installed symmetrically and the side walls are hinged to the assembly frames; a connecting beam is fixedly installed on the inner wall of the sampling rack, and a hydraulic cylinder is hingedly installed between the side wall of the connecting beam and the outer wall of the grab bucket.

[0015] As a further improvement of the above solution, the two opposite side walls of the connecting beam are fixedly connected with a first connecting member, the outer wall of the grab bucket is fixedly installed with a second connecting member, and a hydraulic cylinder is installed between the first connecting member and the second connecting member.

[0016] Through the above technical solution, by controlling the operation of the hydraulic cylinder, the sampling operation of the clamping claws of the two sets of grab buckets can be driven.

[0017] As a further improvement of the above solution, a hanger is fixedly installed on the upper surface of the sampling rack.

[0018] As a further improvement of the above solution, a compressed gas tank, a pressure sensor and a control unit are installed inside the rotating bin, and an exhaust pipe is installed on the top wall of the rotating bin, and a one-way valve and a pressure relief valve are installed on the inner wall of the exhaust pipe.

[0019] Through the above technical solution, the pressure sensor detects the changes in the internal air pressure of the rotating chamber. When the internal air pressure of the rotating chamber increases with the water depth, the pressure sensor detects the pressure signal, and releases the internal gas of the rotating chamber from the exhaust pipe by controlling the pressure relief valve, thereby achieving the air pressure balance in the rotating chamber. When the device floats up, the internal air pressure of the rotating chamber increases, the pressure sensor detects the pressure signal, and the exhaust valve installed at the output end of the compressed gas tank introduces the inert gas in the tank into the rotating chamber, and balances the air pressure in the rotating chamber through the air replenishment operation. This ensures that the camera and its electronic components can operate stably, and at the same time effectively ensures the air pressure balance in the rotating chamber, avoids the glass fogging caused by air pressure changes, and ensures the photographic clarity of the camera body in the rotating chamber.

[0020] A seabed sampling and observation system includes a modem and an intelligent terminal. The intelligent terminal is connected to the modem via a network cable and is used to send control signals to a camera, receive photographic information from the camera, and display it accordingly.

[0021] Through the above technical solution, information and data interaction between the smart terminal and the camera is achieved through the modem, and wired transmission makes data transmission faster and more stable.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] A seabed sampling booster device and observation system of the present invention, by setting multiple groups of water pumps as booster components, can quickly restore the position balance of the device when the sampling device is offset due to ocean currents or wind and waves; using a water pump as a power source has many advantages, such as low noise, good concealment, and low blank shot effect; at the same time, during the water intake process of the booster component, a large amount of water flows into the connecting pipe through the water inlet pipe and is then output from the water pump. Therefore, when a large amount of water flows into the water inlet pipe, it will flush the outer wall of the observation window and quickly flush the observation window. When foreign matter appears in the observation window, the observation window can be quickly cleaned by the operation of the water pump, which greatly ensures that the camera can operate clearly and improves the shooting clarity.

The connecting pipe 19 is a "mouth"-shaped pipeline. The connecting pipe 19 is hoisted below the mounting platform 3. A connecting pipe 21 is connected between the connecting pipe 19 and multiple groups of water pumps 10. The water inlet pipe 1901 is installed on the side of the connecting pipe 19, and the water inlet position of the water inlet pipe 1901 is suitable for the observation window 6. The water inlet cover 20 is installed at the water inlet end of the water inlet pipe 1901. The water inlet cover 20 increases the water inlet range so that the water flow of the incoming water can clean the observation window 6 along a large range;

[0036] The adjustment component includes a drive frame 11, a second motor 12 and a rotating belt 18. The drive frame 11 is placed on the upper surface of the support platform 8 and on one side of the assembly frame 9. The second motor 12 is installed in the drive frame 11. A drive groove 13 is opened on the inner wall of the assembly frame 9. The output end of the second motor 12 is connected to a driving shaft 14, and the driving shaft 14 is connected to the inside of the driving groove 13. The connecting shaft between the water pump 10 and the assembly frame 9 is a driven shaft 15, and the driven shaft 15 is also connected to the driving groove 13. A first turntable 16 is installed around the driving shaft 14, and a second turntable 17 is installed around the driven shaft 15. A rotating belt 18 is installed between the first turntable 16 and the second turntable 17;

[0037] Support frames 23 are fixedly installed on the front and rear end surfaces of the sampling rack 1, and two sets of grab buckets 24 are installed symmetrically and the side walls are hinged to the support frames 23; the first connecting parts 26 are fixedly connected to the opposite side walls of the connecting beam 25, and the second connecting parts 27 are fixedly installed on the outer wall of the grab bucket 24.

[0038] Implementation principle: The sampling rack 1 is connected to the hanger 2 through a winch sling, and then the entire sampling rack 1 is lowered into the water. During the sinking process of the sampling rack 1, the ultra-short baseline positioning mechanism cooperates with the acoustic transducer installed on the hull and the acoustic transponder installed on the sampling rack 1 to achieve accurate underwater positioning of the equipment; when the sampling rack 1 tilts due to the ocean current, the water pump 10 corresponding to the tilt direction is controlled to work and the guide nozzle 22 is adjusted to the corresponding angle. The water pump 10 sprays water from the guide nozzle 22, applying thrust to the sampling rack 1 and quickly correcting the roll of the sampling rack 1; at the same time, the second motor 12 can be controlled to adjust the multiple groups of guide nozzles 22 to a vertical upward or vertical downward state, which can accelerate the sinking or floating of the sampling rack 1;

A one-way valve 31 and a pressure relief valve 32 are installed on the inner wall of the exhaust pipe 30.

[0041] Implementation principle: The pressure sensor detects the change of the internal air pressure of the rotating warehouse 5. When the internal air pressure of the rotating warehouse 5 increases with the change of water depth, the pressure sensor detects the pressure signal and releases the internal gas of the rotating warehouse 5 from the exhaust pipe 30 by controlling the pressure relief valve 32, thereby achieving the air pressure balance in the rotating warehouse 5; when the device floats up, the internal air pressure of the rotating warehouse 5 increases, the pressure sensor detects the pressure signal, and the exhaust valve installed at the output end of the compressed gas tank 29 introduces the inert gas in the tank into the rotating warehouse 5, and balances the air pressure in the rotating warehouse 5 through the air replenishment operation; ensures that the camera 7 and its electronic components can operate stably, and at the same time effectively ensures the air pressure balance in the rotating warehouse 5, avoids the glass fogging caused by air pressure changes, and ensures the photography clarity of the camera 7 in the rotating warehouse 5.

[0042] Example 3: A seabed sampling and observation system includes a modem and an intelligent terminal. The intelligent terminal is connected to the modem via a network cable to send control signals to the camera 7, receive photographic information from the camera 7, and display it accordingly.
