By adopting the above platform staff in a safe area, they can remotely control the variable volume adaptive depth adjustment small ocean exploration platform carrying the ocean exploration equipment to automatically rise and fall, which greatly reduces the possibility of danger to the staff during this process and improves work efficiency. In the specific ocean exploration operation, the oil inlet of the oil bag 2 is controlled by the hydraulic pump station 3 to adjust and control its volume, thereby changing the buoyancy of the entire platform, and by changing its buoyancy, the rise and fall of the platform is controlled.

[0023] Furthermore, the bracket 1 is welded as a whole with a steel material; the bottom of the bracket 1 adopts a rectangular frame structure, and the bracket 1 is arranged in an inclined manner. By adopting the above bracket 1, the structural strength is ensured and the service life is increased.

[0024] Furthermore, the oil bladder 2 includes an inner oil bladder baffle 201, which is fixed on the outer wall of the bracket 1; the inner oil bladder baffle 201 is connected to the outer oil bladder baffle 202 through a corrugated thin-walled bladder body 203 to form a fan-shaped structure; the top of the outer oil bladder baffle 202 is hinged to the bracket 1 through a hinge bolt and its opening and closing is controlled by the contraction of the corrugated thin-walled bladder body 203. The above-mentioned oil bladder 2 is convenient to control its volume change by injecting oil into it, thereby changing its buoyancy under water. In the specific working process, hydraulic oil is filled into the oil bladder 2 through the hydraulic pump station 3, so that the oil bladder 2 expands, the volume increases, and the buoyancy increases.

[0025] Further, the inner oil bag baffle 201 is connected to the hydraulic pump station 3 through an oil pipe. By connecting the oil pipe to the inner oil bag baffle 201, it is ensured that the oil pipe will not change with the contraction of the oil bag 2, thereby ensuring the reliability of the oil pipe connection.

[0026] Furthermore, the inner oil bag baffle 201 and the outer oil bag baffle 202 are made of polymer materials, and the corrugated thin-walled bladder body 203 is made of rubber materials. The corrugated thin-walled bladder body 203 and the inner oil bag baffle 201 and the outer oil bag baffle 202 are bonded together by vulcanization technology to form a closed structure. By using the above materials, the functional structure of the oil bag 2 is guaranteed while extending its service life.

[0027] Furthermore, the hydraulic pump station 3 includes a motor 301, a sealed housing 302, a flange 303, a proportional flow valve 304, a hydraulic pump 305, an oil pipe 306 and a motor seat 307; the output shaft of the motor 301 is connected to the input shaft of the hydraulic pump 305 through the flange 303, and the motor 301 is bolted and fixed to the top of the oil tank 4 through the motor seat 307; the oil inlet and the oil outlet of the hydraulic pump 305 are respectively connected to the oil pipe 306, the proportional flow valve 304 is installed on the oil pipe 306, and the sealed housing 302 is arranged outside the entire hydraulic pump station 3. The above-mentioned hydraulic pump station 3 can be used for the purpose of pumping oil, thereby controlling the volume change of the oil bag 2 to change the buoyancy of the platform.

[0029] Furthermore, the regulating and controlling system 5 includes a pressure sensor 501, a speed sensor and a corresponding controller; the pressure sensor 501 is used to sense the seawater pressure, thereby controlling the position of the small ocean exploration platform at the depth of the ocean. The regulating and controlling system 5 can realize the automatic control of the entire platform.

[0030] Embodiment 2: An operating method of a variable volume adaptive depth adjustment small ocean exploration platform: By mounting the detection device 6 on the bracket 1, in the initial stage, the hydraulic pump station 3 controls the oil bag 2 to shrink, thereby minimizing the buoyancy of the platform, and the platform is lowered into the ocean as a whole. At this time, the platform descends under its own gravity. During the descent, the pressure of the seawater is sensed by the pressure sensor 501, and the corresponding descent depth is calculated. After reaching the specified depth, detection is performed by the detection device 6; When it is necessary to control the platform to rise, the hydraulic pump station 3 is started to adjust the oil volume in the oil bag 2 and the oil tank 4, so that the buoyancy generated by the platform in the water changes with the change of volume, changing the ratio of buoyancy to gravity, thereby making the platform rise under the action of buoyancy and carrying the detection equipment 6 to rise.

[0031] Embodiment 3: A variable volume adaptive depth adjustment small ocean exploration platform includes a bracket, on which an oil tank and a hydraulic pump station are fixedly installed, and two oil bags with fan-shaped cross-sections are symmetrically installed and fixed on the left and right sides of the bracket. According to the force calculation formula of an object in water, changing the weight of an object in water while keeping the volume unchanged or changing the volume of an object while keeping the weight unchanged can change the force state of the object in water, thereby making it float or sink. The variable volume adaptive depth adjustment small ocean exploration platform designed and invented relies on changing its volume to achieve its sinking and floating in water.

[0032] The change of the volume of the variable volume adaptive depth adjustment small ocean exploration platform is achieved through a variable volume device. The variable volume device consists of an oil tank, a hydraulic pump station, an oil bag, and corresponding hydraulic valves. The oil bag is installed on the outside of the variable volume adaptive depth adjustment small ocean exploration platform, and the oil pipe is connected to the internal oil tank and hydraulic pump. When the oil in the oil tank is injected into the oil bag by the hydraulic pump, the volume of the oil bag will increase, and the buoyancy of the variable volume adaptive depth adjustment small ocean exploration platform will gradually increase and rise. Conversely, the hydraulic pump draws the oil in the oil bag back to the oil tank, the volume of the oil bag decreases, and the buoyancy of the variable volume adaptive depth adjustment small ocean exploration platform decreases accordingly. When the gravity is greater than the buoyancy, the variable volume adaptive depth adjustment small ocean exploration platform gradually sinks.

[0033] The overall tilt design of the bracket is integrated with overall welding to achieve the design goal of increasing strength and compact space layout. At the same time, the design of the rectangular frame at the bottom of the support frame can prevent the variable volume adaptive depth adjustment small ocean exploration platform from being unable to float due to being stuck in the seabed mud and sea sand, which produces a large adsorption force.

[0034] The control system includes pressure sensors, speed sensors, and corresponding software and hardware. The pressure sensor is installed to control the depth of the ocean where the small ocean exploration platform is located through the size of the seawater pressure; a proportional flow valve is installed on the pipeline, and the size of the proportional flow valve opening is adjusted by detecting the vertical speed, thereby controlling the speed of the oil bag volume change; the shell is sealed with pressure-resistant and corrosion-resistant materials, and the exchange of electrical energy and data is carried out through watertight cables.

[0035] The fuel tank is designed to be cylindrical in shape, in order to evenly bear the underwater pressure and reduce stress concentration; the fuel tank and the sealed shell are designed with a number of reinforcing ribs at the bottom and around the sides, and components made of fiberglass are used to increase the wall thickness of the tank body. Fiberglass has the characteristics of high strength and low density. The design purpose is not only to increase the strength of the fuel tank and the sealed shell, but also to reduce their weight.

[0036] The design of the oil bladder, the main material of the oil bladder baffle is polymer material, polytetrafluoroethylene can be selected; the shrinking corrugated thin wall is mainly made of rubber material, chloroprene rubber is selected, chloroprene rubber has strong oil resistance, corrosion resistance and aging resistance. The shrinking corrugated thin wall can prevent the oil bladder from being frequently pulled up and causing the oil bladder to fail due to aging. At the same time, the volume of the oil bladder is much larger than the minimum volume of oil required to discharge into the oil bladder to make the variable volume adaptive depth adjustment small ocean detection platform float up. When the variable volume adaptive depth adjustment small ocean detection platform is in the water, it may be affected by external forces such as seabed silt and water grass entanglement in the actual working environment to prevent it from floating up. More oil can be sucked into the oil bladder, so that the variable volume adaptive depth adjustment small ocean detection platform can obtain greater buoyancy to offset the influence of external forces.

[0037] In order to ensure that the oil bladder can work normally underwater and ensure that the shrink thin wall can still ensure the sealing performance of the oil bladder when it is damaged by external emergencies, the specific design scheme adopted is: the spherical surface of the oil bladder is designed with a corrugated structure to prevent the oil bladder from being stretched and compressed when absorbing and discharging oil, causing the aging and failure of the oil bladder. In order to ensure the overall service life of the oil bladder, chloroprene rubber is used as the matrix and high-quality dense nylon fabric is used as the support. The two materials of different properties are combined into one through the pressure injection molding process to form a spherical structure of the oil bladder. The purpose of this production is to utilize the moderate toughness, excellent elasticity, seawater corrosion resistance and impact resistance of chloroprene rubber materials to improve the strength and impact resistance of the component itself. The hardness of the product is about 80° Shore. In order to further enhance the overall tear resistance of the oil bladder, in the rubber product process, a high-quality dense nylon fabric fiber fabric is pre-laid in the mold. The fabric adopts a plain weave to increase its warp and weft density or adds coarser aramid fiber on the basis of the plain weave to improve the strength and tear resistance of the overall component.
