Description

Technical Field

[0001] The present invention relates to the technical field of geophysical equipment, and specifically provides a geophysical equipment and data processing method for deep-sea exploration. Background Art

[0002] Geophysical exploration is an exploration technology that uses the principles and methods of geophysics for geological survey and research. Due to the differences in rock types, geological structures, and groundwater characteristics that make up the earth's crust, a unique physical field is formed. Through instrument testing and analysis of the measured data, the underground geological structure and ore body distribution can be inferred. There are mainly gravity exploration, magnetic exploration, electrical exploration, seismic exploration, radioactive exploration, and physical logging of certain parameters. Among them, gravity exploration is further divided into land gravity measurement and marine gravity measurement.

[0003] The ocean occupies 70% of the earth's surface area. To obtain the gravity distribution data on the earth's surface, marine gravity measurement is a major topic. When conducting gravity exploration in this area, corresponding marine detectors are required. However, since the temperature in the deep ocean is lower than that on land, during the actual use of the marine gravimeter, as the gravimeter sinks deeper into the ocean, the temperature inside its space decreases accordingly, which in turn affects the accuracy of the data detected by the IMU module and the measurement module.

[0004] In the related art, the space where the IMU module and the measurement module are located is heated to increase its temperature. However, as the measurement time lengthens and the marine gravimeter sinks deeper, the originally heated temperature drops rapidly, which also affects the accuracy of the data detected by the subsequent IMU module and the measurement module.

[0005] The information disclosed in this background art section is only intended to deepen the understanding of the overall background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

[0011] Preferably, rubber rings are installed on the inner and outer walls of the connecting ring, the tops of the two groups of rubber rings are attached to the bottom of the heating and heat preservation plate, an assembly ring is fixedly connected to the bottom of the heating and heat preservation plate, and the assembly ring is threadedly fitted with the threaded circular ring.

[0012] Preferably, two symmetrically arranged connecting blocks are fixedly connected to the outer surface of the heat insulation cylinder, and instrument handles are installed at opposite ends of the two connecting blocks.

[0013] Preferably, an air release valve is arranged on the top of the top seat. Two water-tight heads arranged side by side are installed on the top of the top seat, and the two water-tight heads are respectively located on both sides of the air release valve. A counter is installed on the top of the top seat, and the counter is located behind the air release valve.

[0014] Preferably, an eyepiece seat is installed on the top of the top seat, and an eyepiece cylinder is installed on the top of the eyepiece seat.

[0015] Preferably, the data processing method of this geophysical equipment is as follows:

[0016] S1. The staff removes the top seat. At this time, the top of the heat preservation interlayer is exposed. Then, after the staff injects the liquid to be heated into it, the top seat is assembled with the heat insulation cylinder again. Then, a rotational force in a set direction is applied to the hollow ring body to make it move upward along the outer surface of the threaded ring cylinder until the height position of its bottom is higher than the position of the base. At this time, the staff applies rotational forces to the four protection rings in turn to drive the sleeve to rotate 180° along the outer surface of the T-shaped column and adjust it outward from directly below the base.

[0017] S2. Then, the equipment is lowered into the deep sea, and the turbine motor is started to drive the fan blade assembly to rotate in a set direction, so as to increase the power received by the equipment when it is lowered into the water or floats out of the water.

[0018] S3. At the same time, the battery in the battery box provides electrical energy for the heating tube. The heating tube converts electrical energy into heat energy to heat the liquid in the space of the heat preservation interlayer until the temperature of this liquid monitored in real time by the temperature sensor reaches the set value, and then the supply of electrical energy is stopped. On the contrary, when the temperature sensor detects that the temperature of this liquid is lower than another set value, it immediately prompts the battery box electrically connected to it to provide the operating electrical energy required by the heating tube.

[0019] S4. When the equipment reaches the set depth in the sea, the gravity value is measured at this depth position through the measurement module and the IMU module, and the measured data is fed back to the processing system electrically connected to it.

[0020] S5. After the data measurement and processing are completed, the equipment is taken out of the deep sea. Then, a rotational force in a set direction is applied to the top seat to drive the heating and heat preservation plate to drive the assembly ring to rotate along the inner wall of the threaded ring, so that the two gradually separate. At this time, as the top seat gradually moves upward, the two suspension rods can drive the cushion ring and the two brush assemblies to move upward accordingly. At this time, the two brush assemblies can brush against the opposite outer walls of the heat conduction cylinder and the heat insulation cylinder accordingly.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, when the liquid temperature inside the thermal insulation interlayer space is detected by the temperature sensor to be lower than the set value, the battery box electrically connected thereto is immediately prompted to provide the electric energy required for the heating pipe to operate. The heating pipe converts the electric energy into heat energy to heat the liquid inside the thermal insulation interlayer space until the temperature of the liquid monitored in real time by the temperature sensor reaches the set value, and then the supply of electric energy is stopped. The heat conduction cylinder itself is made of a heat-conducting material, which can facilitate the transfer of the temperature of the heated liquid inside the thermal insulation interlayer space to the surrounding of the IMU module, so as to ensure that the IMU module is always in a relatively stable temperature environment in the deep sea, thereby indirectly improving the accuracy of the data detected by the IMU module and the measurement module.

[0023] 2. In the present invention, as an upward pulling force is applied to the top seat, the two groups of suspension rods can be prompted to drive the gasket ring and the two groups of brush components to move upward accordingly. At this time, the two groups of brush components can brush the opposite outer walls of the heat conduction cylinder and the heat insulation cylinder, and then the calcified water scale generated on the inner wall of the space of this thermal insulation interlayer due to the long-term retention of the liquid can be brushed off, so as to effectively maintain the heat conduction effect of the heat conduction cylinder.

[0024] 3. In the present invention, by applying an external force to the protective ring, the sleeve is driven to rotate 180° along the outer surface of the T-shaped column and adjusted outward from directly below the base. Then, by operating the turbine motor, the fan blade assembly is prompted to rotate in the set direction, so as to increase the power received by the equipment when it enters the water or emerges from the water surface, thereby effectively reducing the time required for the geophysical equipment to enter and exit the water and improving the work efficiency.

[0025] 4. In the present invention, after the turbine acceleration assembly is retracted directly below the base, by applying a rotational force in the set direction to the hollow ring body, it is prompted to move downward along the outer surface of the threaded ring cylinder until the height position of its bottom is lower than the position of the turbine acceleration assembly. Then, when the equipment is placed, the hollow ring body directly contacts the bottom surface, thereby effectively preventing the turbine acceleration assembly from contacting the bottom surface and being worn. At the same time, the fourteen groups of turbine acceleration assemblies are limited within the space range enclosed by the hollow ring body, so as to reduce the lateral space occupied by the entire equipment.

[0037] Please refer to Figures 1-7 , an embodiment provided by the present invention:

[0038] A geophysical equipment for deep-sea exploration, comprising a base 1. An IMU module 2 is installed on the top of the base 1. An attitude sensor 3 is installed on the outer surface of the IMU module 2. A measurement module is installed on the top of the IMU module 2. A heat conduction cylinder 4 is fixedly installed on the top of the base 1 and surrounds the periphery of the IMU module 2. A threaded ring cylinder 5 is fixedly installed on the top of the base 1 and surrounds the periphery of the heat conduction cylinder 4. The top of the threaded ring cylinder 5 is fixedly connected to a heat insulation cylinder 6. A heat preservation layer 7 is formed between the heat insulation cylinder 6 and the heat conduction cylinder 4. The top of the heat conduction cylinder 4 is fixedly connected to a threaded circular ring 8. A top seat 9 is movably installed on the top of the heat insulation cylinder 6. A heating and heat preservation plate 10 is fixedly installed on the inner wall of the top seat 9. A connecting ring 11 is fixedly installed at the bottom of the heating and heat preservation plate 10. A sealing ring 12 is fixedly installed at the bottom of the connecting ring 11. Two groups of heating tubes 13 arranged front and back are installed at the bottom of the sealing ring 12. A battery box 14 is installed on the top of the heating and heat preservation plate 10, and the battery box 14 is electrically connected to the heating tubes 13. Two groups of parallel arranged suspension rods 15 are fixedly connected to the bottom of the sealing ring 12. A temperature sensor 16 is connected to the front of one group of suspension rods 15, and the temperature sensor 16 is electrically connected to the battery box 14.

[0039] When this equipment reaches a certain depth in the sea, the gravity value at this depth position is measured through the measurement module and the IMU module 2, and the measured data is fed back to the processing system electrically connected thereto, so as to obtain the gravity value at this position and depth in the deep sea. Among them, the battery inside the battery box 14 provides electrical energy for the heating tube 13, and the heating tube 13 converts the electrical energy into heat energy to heat the liquid inside the heat preservation interlayer 7 space until the temperature of this liquid monitored in real time by the temperature sensor 16 reaches the set value, then the supply of electrical energy stops. On the contrary, when the temperature sensor 16 detects that the temperature of this liquid is lower than another set value, it immediately prompts the battery box 14 electrically connected thereto to provide the electrical energy required for the operation of the heating tube 13. The heat conduction cylinder 4 itself is made of heat-conducting material, which can facilitate the transfer of the temperature of the liquid that has been heated inside the heat preservation interlayer 7 space to the periphery of the IMU module 2, so as to ensure that the IMU module 2 is always in a relatively stable temperature environment in the deep sea, and then indirectly improve the accuracy of the data detected by the IMU module 2 and the measurement module.

[0040] Pad rings 17 are fixedly installed at the bottoms of the two groups of suspension rods 15. Brush hair assemblies 18 are fixedly connected to the inner wall and the outer wall of each pad ring 17, and one ends of the two groups of brush hair assemblies 18 are respectively attached to the opposite outer walls of the heat conduction cylinder 4 and the heat insulation cylinder 6.

[0041] With an upward pulling force applied to the top seat 9, the two groups of suspension rods 15 can drive the pad rings 17 and the two groups of brush hair assemblies 18 to move upward accordingly. At this time, the two groups of brush hair assemblies 18 can brush the opposite outer walls of the heat conduction cylinder 4 and the heat insulation cylinder 6 accordingly, and then the calcified water scale generated on the inner wall of the space of this heat preservation interlayer 7 due to the long-term retention of the liquid can be brushed off, so as to effectively maintain the heat conduction effect of the heat conduction cylinder 4. At the same time, when the top seat 9 is in contact with the top of the heat insulation cylinder 6, it is set that the pad ring 17 is at the bottommost of the heat preservation interlayer 7. At this time, the fine particles or the later-generated calcified water scale in the liquid inside this heat preservation interlayer 7 will be intercepted by the pad ring 17 to prevent them from depositing on the top of the base 1, resulting in difficult cleaning in the later stage.

[0042] Four groups of equally spaced T-shaped columns 19 are fixedly installed at the bottom of the base 1. Sleeve tubes 20 are movably sleeved on the outer surfaces of the four groups of T-shaped columns 19. A protective ring 21 is fixedly connected to the outer surface of each sleeve tube 20. Four groups of annularly arranged connecting rods 22 are fixedly connected to the inner wall of the protective ring 21. A turbine motor 23 is installed at one end of the four groups of connecting rods 22. An inverter is installed at the output end of the turbine motor 23. A fan blade assembly 24 is installed at the output end of the inverter.

[0043] Since the T sleeve 20 and the T-shaped column 19 are in a non-fixed fitting state, the turbine acceleration assembly composed of the sleeve 20, the protective ring 21, the connecting rod 22, the turbine motor 23, the frequency converter and the fan blade assembly 24 can adjust its position relative to the base 1. Among them, when the turbine acceleration assembly is not in use, it is stored directly below the base 1 to reduce the lateral space occupied by the entire equipment. Conversely, when the turbine acceleration assembly needs to be used, the staff applies a rotational force to the four groups of protective rings 21 in sequence to drive the sleeve 20 to rotate 180° along the outer surface of the T-shaped column 19, adjust it outward from directly below the base 1, and then operate the turbine motor 23 to drive the fan blade assembly 24 to rotate in the set direction, so as to increase the power received by the equipment when it enters the water or emerges from the water surface, thereby effectively reducing the time required for the geophysical equipment to enter and exit the water and improving work efficiency.

[0044] A limiting ring 25 is fixedly connected to the outer surface of the heat insulation cylinder 6. A circular fitting groove 26 is provided at the bottom of the limiting ring 25. Four equally spaced T-shaped blocks 27 are clamped on the inner wall of the circular fitting groove 26. The bottoms of the four T-shaped blocks 27 are fixedly connected with telescopic cylinders 28. The bottoms of the four telescopic cylinders 28 are fixedly connected with a hollow ring body 29, and the hollow ring body 29 and the threaded ring cylinder 5 are connected by threaded fitting.

[0045] After the turbine acceleration assembly is retracted directly below the base 1, by applying a rotational force in a set direction to the hollow ring body 29, it is urged to move downward along the outer surface of the threaded ring cylinder 5 until the height position of its bottom is lower than the position of the turbine acceleration assembly. Then, when the equipment is placed, the hollow ring body 29 directly contacts the bottom surface, effectively preventing the turbine acceleration assembly from contacting the bottom surface and being worn. Moreover, as the hollow ring body 29 rotates, the telescopic cylinder 28 can correspondingly drive the T-shaped block 27 to rotate along the inner wall of the circular fitting groove 26. At the same time, as the hollow ring body 29 moves upward or downward, the telescopic cylinder 28 can correspondingly receive an upward pushing force or a downward pulling force to change its overall length accordingly. At the same time, since the telescopic cylinder 28 and the T-shaped block 27 connect the hollow ring body 29 and the limiting ring 25, it can effectively prevent the hollow ring body 29 from detaching from the threaded ring cylinder 5 due to the impact force brought by the water body after the equipment enters the water.

[0046] Rubber rings 30 are installed on both the inner wall and the outer wall of the connecting ring 11, and the tops of the two rubber rings 30 are in contact with the bottom of the heating and heat preservation plate 10. The bottom of the heating and heat preservation plate 10 is fixedly connected with an assembly ring 31, and the assembly ring 31 and the threaded circular ring 8 are connected by threaded fitting.

[0047] After the top seat 9 and the heat insulation cylinder 6 are combined, the structure formed by the two groups of rubber rings 30 and the connecting ring 11 can block the space above the heat preservation interlayer 7, thereby effectively preventing the replacement of seawater with the liquid inside the heat preservation interlayer 7. By screwing and assembling the assembly ring 31 and the threaded ring 8, the firmness of the combination between the top seat 9 and the heat insulation cylinder 6 can be improved.

[0048] Two symmetrically arranged connecting blocks 32 are fixedly connected to the outer surface of the heat insulation cylinder 6. Instrument handles 33 are installed at opposite ends of the two connecting blocks 32. An air release valve 34 is arranged at the top of the top seat 9. Two water-tight heads 35 arranged side by side are installed at the top of the top seat 9, and the two water-tight heads 35 are respectively located on both sides of the air release valve 34. A counter 36 is installed at the top of the top seat 9, and the counter 36 is located behind the air release valve 34. An eyepiece holder 37 is installed at the top of the top seat 9, and an eyepiece tube 38 is installed at the top of the eyepiece holder 37.

[0049] The setting of the instrument handle 33 facilitates the handling of this equipment. The setting of the air release valve 34 can prevent air from being adsorbed when the top seat 9 is drained.

[0050] The data processing method of this geophysical equipment is as follows:

[0051] S1. The staff removes the top seat 9. At this time, the top of the heat preservation interlayer 7 is exposed. Then, after the staff injects the liquid to be heated into it, the top seat 9 and the heat insulation cylinder 6 are assembled again. Then, a rotational force in a set direction is applied to the hollow ring body 29, causing it to move upward along the outer surface of the threaded ring cylinder 5 until the height position of its bottom is higher than the position of the base 1. At this time, the staff applies rotational forces to the four groups of protective rings 21 in sequence to drive the sleeve 20 to rotate 180° along the outer surface of the T-shaped column 19 and adjust it outward from directly below the base 1.

[0052] S2. Then, this equipment is lowered into the deep sea, and by starting the turbine motor 23, it is prompted to drive the fan blade assembly 24 to rotate in a set direction, so as to increase the power received by this equipment when it is lowered into the water or floats out of the water surface.

[0053] S3. At the same time, the battery inside the battery box 14 provides electrical energy for the heating pipe 13. The heating pipe 13 converts electrical energy into heat energy to heat the liquid inside the space of the heat preservation interlayer 7 until the temperature of this liquid monitored in real time by the temperature sensor 16 reaches the set value, and then the supply of electrical energy is stopped. On the contrary, when the temperature sensor 16 detects that the temperature of this liquid is lower than another set value, it immediately prompts the battery box 14 electrically connected to it to provide the electrical energy required for the operation of the heating pipe 13.

[0054] S4. When this equipment reaches the sea at the set depth, the gravity value is measured at this depth position through the measurement module and the IMU module 2, and the measured data is fed back to the processing system electrically connected thereto;

[0055] S5. After the data measurement and processing are completed, take this equipment out of the deep sea. Then, apply a rotational force in the set direction to the top seat 9 to cause the heating and insulation plate 10 to drive the assembly ring 31 to rotate along the inner wall of the threaded ring 8, so that the two gradually separate. At this time, as the top seat 9 gradually moves upward, the two suspension rods 15 can correspondingly drive the cushion ring 17 and the two brush components 18 to move upward accordingly. At this time, the two brush components 18 can correspondingly brush the opposite outer walls of the heat conduction cylinder 4 and the heat insulation cylinder 6.

[0056] Working principle: Apply a rotational force in the set direction to the hollow ring body 29 to cause it to move downward or upward along the outer surface of the threaded ring cylinder 5, so as to adjust the position of the hollow ring body 29 corresponding to the turbine acceleration component. When the position of the bottom of the hollow ring body 29 is higher than the turbine acceleration component, apply a rotational force to the four protective rings 21 in sequence to drive the sleeve 20 to rotate 180° along the outer surface of the T-shaped column 19 and adjust it outward from directly below the base 1. Then, when this equipment enters or exits the water, start the turbine motor 23 to cause it to drive the fan blade assembly 24 to rotate in the set direction, so as to increase the power received by this equipment when entering the water or surfacing from the water. And before this equipment enters the water, start the temperature sensor 16. When it is monitored in real time that the liquid temperature in the space of the heat preservation interlayer 7 is lower than the set value, immediately cause the battery box 14 electrically connected thereto to provide the electric energy required for the operation of the heating pipe 13. The heating pipe 13 converts the electric energy into heat energy to heat the liquid in the space of the heat preservation interlayer 7 until the temperature of this liquid monitored in real time by the temperature sensor 16 reaches the set value, and then stop the supply of electric energy. Then, transfer the temperature of the liquid that has been heated in the space of the heat preservation interlayer 7 to the periphery of the IMU module 2 through the heat conduction cylinder 4, so as to ensure that the IMU module 2 is always in a relatively stable temperature environment in the deep sea.

9. A geophysical equipment for deep-sea exploration according to any one of claims 1-8, characterized in that, The data processing method of this geophysical equipment is as follows: S1. The staff removes the top seat (9). At this time, the top of the heat preservation interlayer (7) is exposed. Then, after the staff injects the liquid to be heated into it, the top seat (9) is assembled with the heat insulation cylinder (6) again. Then, a rotational force in a set direction is applied to the hollowed-out ring body (29) to make it move upward along the outer surface of the threaded ring cylinder (5) until the height position of its bottom is higher than the position of the base (1). At this time, the staff applies rotational forces to the four protective rings (21) in turn to drive the sleeve (20) to rotate 180° along the outer surface of the T-shaped column (19) and adjust it outward from directly below the base (1); S2. Then, this equipment is lowered into the deep sea. By starting the turbine motor (23), it is driven to drive the fan blade assembly (24) to rotate in a set direction to increase the power received by this equipment when it is lowered into the water or floats out of the water. S3. Meanwhile, the battery inside the battery box (14) provides electrical energy for the heating tube (13). The heating tube (13) converts the electrical energy into heat energy to heat the liquid inside the space of the heat preservation interlayer (7) until the temperature of this liquid monitored in real time by the temperature sensor (16) reaches the set value, then the supply of electrical energy stops. On the contrary, when the temperature sensor (16) detects that the temperature of this liquid is lower than another set value, it immediately prompts the battery box (14) electrically connected to it to provide the electrical energy required for the operation of the heating tube (13). S4. When this equipment reaches the set depth in the sea, the gravity value is measured at this depth position through the measurement module and the IMU module (2), and the measured data is fed back to the processing system electrically connected to it. S5. After the data measurement and processing are completed, this equipment is taken out of the deep sea. Then, by applying a rotational force in a set direction to the top seat (9), the heating and heat preservation plate (10) is prompted to drive the assembly ring (31) to rotate along the inner wall of the threaded ring (8) so that the two gradually separate. At this time, as the top seat (9) gradually moves upward, the two suspension rods (15) can correspondingly drive the gasket ring (17) and the two brush components (18) to move upward accordingly. At this time, the two brush components (18) can correspondingly brush the opposite outer walls of the heat conduction cylinder (4) and the heat insulation cylinder (6).
