DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] A drilling and sampling device for marine geological exploration according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0028] See also Figure 1-Figure 5 According to an embodiment of the present application, a drilling and sampling device for marine geological exploration includes: a rapid sinking main mechanism 10, a lifting component 20 and a sampling component 30.

[0029] The rapid sinking mechanism 10 supports the lifting assembly 20 and sampling assembly 30, and can drive the entire structure of the lifting assembly 20 and sampling assembly 30 to quickly sink to the seabed, thereby increasing the equipment's sinking speed. The lifting assembly 20 and sampling assembly 30 work together to sample the seabed soil.

[0030] The rapid sedimentation main body mechanism 10 includes a seat frame 110, a leg frame 120, a connecting frame 130, an outer cover shell 140, a support seat 150, a first motor 160, a propeller 170 and a first blade 180. The connecting frame 130 connects the seat frame 110 and the outer cover shell 140, and multiple groups of outer cover shells 140 are distributed in a ring array on the outside of the seat frame 110. The support seat 150 is fixed inside the outer cover shell 140, the first motor 160 is installed above the support seat 150, the propeller 170 is arranged at the output shaft end of the first motor 160, and the first blade 180 is tilted and arranged below the blade of the propeller 170. Two groups of leg frames 120 are symmetrically installed on both sides below the seat frame 110. The lifting assembly 20 is installed on the seat frame 110 to drive the sampling assembly 30 to rise and fall.

[0031] The operating principle of this marine geological exploration drilling and sampling equipment is as follows: the entire drilling and sampling equipment is lowered from a vessel into the seawater using a lifting rope, and then the rope is quickly released. Simultaneously, a first motor 160 in the rapid sinking main mechanism 10 drives a propeller 170 at the end to rotate. The rotating propeller 170 drives the outer housing 140 to rapidly move toward the seabed via the support base 150. The outer housing 140, which rapidly moves toward the seabed, drives the seat frame 110 to rapidly move toward the seabed via the side connector 130, thus enabling the drilling and sampling equipment to rapidly move toward the seabed. When the drilling and sampling equipment is nearly at the seabed, the first motor 160 stops, causing the propeller 170 to stop rotating. Under the buoyancy and resistance of the seawater, the leg frame 120 at the bottom of the seat frame 110 eventually slowly lands on the seabed soil. Compared to traditional seabed geological sampling equipment, this can overcome the resistance and buoyancy of the seawater and rapidly sink the drilling and sampling equipment to the seabed level.

[0032] Before the drilling and sampling equipment lands on the seabed soil, the bottom of the sampling assembly 30 is located above the bottom of the leg frame 120. After the drilling and sampling equipment quickly sinks to the seabed, the lifting assembly 20 gradually moves the sampling assembly 30 downward. Through the cooperation of the lifting assembly 20 and the sampling assembly 30, the seabed soil is sampled. After sampling is completed, the sampling equipment can be lifted by the traction device above the hull to finally obtain the sampled soil.

[0033] As the drilling and sampling equipment rapidly descends into the seawater, floating impurities such as seaweed may enter the interior of the outer housing 140. The first motor 160 drives the propeller 170 to rotate, simultaneously driving the first blade 180 on the propeller 170. The tilted position of the first blade 180 during rotation makes it easier for the first blade 180 to cut and pulverize any seaweed and other impurities that enter the outer housing 140, preventing them from entangling the propeller 170. This ensures stable operation of the propeller 170 driven by the first motor 160 and enables the equipment to descend steadily.

[0034] For specific settings, see Figure 2 The leg frame 120 includes a support rod 121 and a crossbar 122. The top of the support rod 121 is connected to the bottom of the base frame 110. The support rod 121 is tilted, and the crossbar 122 is fixed at the bottom of the support rod 121. The leg frame 120 uses the tilted support rod 121 to support the crossbar 122, increasing the contact area between the leg frame 120 and the seabed soil, allowing the drilling and sampling equipment to be more stably supported above the soil for drilling and sampling.

[0035] For details, please refer to Figure 3The outer shell 140 includes an upper shell 141 and a conical lower shell 142. The upper shell 141 and lower shell 142 are connected, and the support base 150 is fixed inside the upper shell 141. The conical structure of the lower shell 142 makes it easier to fill the upper shell 141 with more seawater. This increases the flow rate of seawater through the upper shell 141, allowing the propeller 170 to quickly discharge the seawater inside the upper shell 141 to the upper part of the upper shell 141 during its rapid rotation.

[0036] Furthermore, the outer shell 140 further includes a grid 143, which is disposed on the top of the upper shell 141. When the drilling and sampling equipment is exposed above the sea surface, the grid 143 has a certain protective effect on the propeller 170.

[0037] In a specific configuration, the rapid subsidence main body mechanism 10 further includes a sensor group 192, which is mounted on the bottom of the seat frame 110. The sensor group 192 may include a pressure sensor, a sonar sensor, a displacement sensor, and the like.

[0038] Furthermore, the rapid sinking main body 10 also includes a light source detection camera 191, which is mounted on the bottom of the base 110. The light source detection camera 191 is configured to include a camera and a searchlight. The searchlight and the camera enable surveyors in the monitoring area to see the specific conditions of the seabed without the need for additional monitoring equipment.

[0039] In the above specific implementation, please refer to Figure 4 Each set of propeller blades 170 is provided with at least two inclined first blades 180 along the blade's inclination. Propeller 170 may have a maximum of four blades, with spaces between adjacent blades. The gaps between propeller 170 blades allow for smooth passage of debris cut by first blades 180. Multiple sets of first blades 180 are arranged along the inclined surfaces of propeller 170 blades, enhancing cutting performance.

[0040] In the above specific implementation, please refer to Figure 5 The lifting assembly 20 includes an electric push rod 210, a vertical rod 220, a fixed rod 230, and a lifting ring 240. The vertical rod 220 connects the fixed rod 230 and the sampling assembly 30. The lifting ring 240 is designed at the top of the vertical rod 220. The electric push rod 210 is mounted above the base 110, and the end of the electric push rod 210 is fixed to the fixed rod 230. The base 110 has a central opening, through which the vertical rod 220 and the sampling assembly 30 can move.

[0041] The output rod end of the electric push rod 210 in the lifting assembly 20 drives the fixed rod 230 to move in the vertical direction, that is, the fixed rod 230 drives the vertical rod 220 and the sampling assembly 30 at the bottom of the vertical rod 220 to move in the vertical direction to adjust the drilling height of the sampling assembly 30.

[0042] The above-mentioned drilling sampling equipment for marine geological exploration, if used for simple drilling sampling, has the following problems: If the sampling device contains air, the overall buoyancy of the device is increased during sinking, making it difficult to sink to the deeper seabed for drilling. If the sampling device does not contain air, the sampled soil is easily lost during the process of being raised by the drilling equipment, resulting in a significant reduction in the sampled soil mass and poor sampling results.

[0043] In the above specific implementation, please refer to Figure 6 and Figure 7 The sampling assembly 30 includes a cylindrical shell 310, a fixing frame 320, a second motor 330, a transmission shaft 340, a spiral blade 350 and a drain pipe 360. The fixing frame 320 is connected to the bottom end of the vertical rod 220 and the top of the cylindrical shell 310, the transmission shaft 340 rotates and passes through the top wall of the cylindrical shell 310, the second motor 330 is installed on the inner side of the fixing frame 320, and the output shaft end of the second motor 330 is connected to the top of the transmission shaft 340, the spiral blade 350 is located inside the cylindrical shell 310, and the spiral blade 350 is fixedly set on the outside of the transmission shaft 340. The bottom end of the spiral blade 350 is arranged parallel to the bottom end of the cylindrical shell 310, and a storage space is reserved between the top of the spiral blade 350 and the top of the cylindrical shell 310. The bottom end of the drain pipe 360 ​​is connected to the top of the cylindrical shell 310, and the drain pipe 360 ​​section is provided with an electric control valve 370. The drilling and sampling equipment for marine geological exploration also includes a leak prevention assembly 40, which includes a lower shell 410, a bracket 420, a baffle plate 430, and a hinge 440. The top outer edge of the lower shell 410 is connected to the bottom outer edge of the cylindrical shell 310. The baffle plates 430 are hingedly connected to the lower shell 410 via the hinge 440. Multiple groups of baffle plates 430 enclose a horizontal circular structure within the lower shell 410. The bracket 420 is located below the baffle plates 430 and is fixed to the lower shell 410. The bracket 420 supports the cylindrical shell 310 and the lower shell 410 below the gap between adjacent baffle plates 430 and moves into the soil layer.

[0044] When the drilling and sampling equipment is lowered into the ocean, the electrically controlled valve 370 is in the open state. During the sinking process, seawater flows in from the bottom of the lower shell 410. Under water pressure, the multiple sets of flaps 430 rotate around the hinges 440 to open inside the lower shell 410. Seawater flows from the lower shell 410 into the cylindrical shell 310 and is ultimately discharged through the drain pipe 360. This allows the air trapped inside the lower shell 410 and cylindrical shell 310 to be expelled, eliminating air from the sampling assembly 30. This reduces the overall buoyancy of the drilling and sampling equipment, making it easier to sink to deeper depths on the seabed.

[0045] After the drilling and sampling equipment is lowered to the seabed surface, the electric push rod 210 drives the vertical rod 220 downward. The downward movement of the vertical rod 220 drives the bottom cylindrical shell 310 and the lower shell 410 into the seabed soil layer. Simultaneously, the output shaft end of the second motor 330 drives the transmission shaft 340 to rotate, which in turn drives the spiral blade 350 to rotate. As the cylindrical shell 310 and the lower shell 410 gradually move downward, the baffle plate 430 at the bottom of the lower shell 410 is tilted inward, and the soil enters the cylindrical shell 310. As the spiral blade 350 gradually enters the cylindrical shell 310, it is gradually stored upward. Excess seawater inside the cylindrical shell 310 is discharged through the drain pipe 360. After sampling is completed, the second motor 330 stops and the electrically controlled valve 370 closes. As the drilling sampling equipment is driven upward by the rope, the soil remaining inside the cylindrical shell 310 moves downward under the action of inertia, and the inclined baffle plate 430 moves downward, so that the multiple baffle plates 430 are enclosed into a circle and blocked by the bracket 420, forming an enclosed space, reducing the loss of sampled soil, and better completing soil sampling.

[0046] When the above-mentioned drilling and sampling equipment for marine geological exploration sinks close to the seabed, if there are a lot of seaweed plants on the seabed, or a large amount of seaweed suddenly floats in the sea water, if the drilling and sampling equipment is not stopped in time, it is easy for the drilling and sampling equipment to be entangled. Forcibly pulling up the sampling equipment may cause damage to the equipment.

[0047] This application also provides an implementation method, please refer to Figure 8 、 Figure 9 and Figure 10The drilling and sampling equipment for marine geological exploration also includes a seaweed cutting mechanism 50, which comprises a conical cover 510, outer ring strips 520, transverse strips 530, a second blade 540, a diversion housing 550, and an inner ring frame 570. The conical cover 510 is fixed to the outside of the bottom of the outer housing 140. The diversion housing 550 connects the outer housing 140 and the conical cover 510. The inner ring frame 570 is rotatably mounted outside the conical cover 510. Multiple sets of outer ring strips 520 are mounted outside the inner ring frame 570, and multiple sets of transverse strips 530 are equidistantly connected to the outer ring strips 520 in a circular array. The second blade 540 is tilted and positioned at the bottom of the transverse strips 530. A mounting opening 560 is provided in the middle of the conical cover 510. The sampling assembly 30 movably extends through the mounting opening 560. The light source detection camera 191 and the sensor assembly 192 are both mounted on the bottom of the conical cover 510.

[0048] When the drilling and sampling equipment is rapidly lowered into the seawater by the cooperation of the first motor 160 and the propeller 170, the second blade 540 inclined below the horizontal strip 530 in the outer ring strip 520 will come into contact with the seawater. Because the second blade 540 is arranged in multiple groups of inclinations in a ring structure, the second blade 540 will drive the horizontal strip 530, the outer ring strip 520, and the inner ring frame 570 to rotate outside the conical cover 510 after coming into contact with the seawater. As the drilling and sampling equipment gradually and rapidly moves toward the seabed, the second blade 540 at the bottom of the horizontal strip 530 will rotate rapidly together with the outer ring strip 520 and the inner ring frame 570. If seaweed suddenly appears under the seawater, the sensor group 192 and the light source detection camera 191 will detect it and quickly stop the drilling equipment from moving toward the seabed. At the same time, under the inertia of the rotation of the outer ring plate 520, the horizontal plate 530, and the second blade 540, when the inclined second blade 540 at the bottom of the horizontal plate 530 comes into contact with the seaweed, the seaweed at the bottom can be quickly cut off, thereby reducing the possibility of the drilling and sampling equipment being entangled by the seaweed and having a good protective effect on the equipment.

[0049] The drilling sampling equipment is provided with a conical structure conical cover 510, so that the seawater at the bottom of the bottom equipment can be better diverted by the conical cover 510, reducing the resistance of the equipment when it sinks downward and increasing the sinking speed of the equipment.

[0050] It should be noted that the specific models and specifications of the first motor 160, light source detection camera 191, sensor group 192, electric push rod 210, second motor 330, and electric control valve 370 are selected based on the actual specifications of the device. The specific selection and calculation method uses existing technology in the field and will not be described in detail here.
