Abstract

The present invention discloses a sample storage device for solid mineral geological exploration, comprising a body, wherein an aggregate assembly for storing combustible ice is provided in the body, so that the liquid nitrogen in the sealing cover also starts to relieve pressure through a regulating valve, thereby realizing refrigeration of the body and the collection box, and at the same time accelerating the internal pressure reduction efficiency, thereby avoiding excessive difference between external pressure and internal pressure of the device, which may cause the body and the collection box to expand and deform, and in severe cases, may cause rupture, resulting in sample loss, thereby effectively avoiding the previous situation in which the device can only store combustible ice samples collected from the ocean when in use. If the combustible ice samples are collected and stored in the ocean and then the device is taken out of the deep sea, the internal air pressure balance box may rupture, resulting in the device being unable to store the combustible ice samples normally.

Description

Technical Field

[0001] The invention relates to the technical field of mineral geological exploration sample storage, in particular to a solid mineral geological exploration sample storage device. Background Art

[0002] Geological and mineral exploration can be carried out by observing and detecting the soil structure of geological layers through industrial microscopes. Soil can be divided into old accumulation soil, general accumulation soil and recent accumulation soil according to the age of accumulation; it can be divided into crushed stone soil, sandy soil, silt soil and clay soil according to particle grading or plasticity index; it can be divided into inorganic soil, organic soil, carbonaceous soil and peat according to the organic matter content; it can be divided into disintegrating soil, soft soil, expansive soil, saline soil, artificial fill, etc. according to the engineering geological significance and the special composition, state and structural characteristics of the soil. Combustible ice is a kind of solid mineral in special demand. Natural gas hydrate is combustible ice. It is an ice-like crystalline substance formed by natural gas and water under high pressure and low temperature conditions. Because it looks like ice and burns when it encounters fire, it is called "combustible ice", "solid gas" and "gas ice".

[0003] The existing patent application number is 202111117691.X, which is a natural resource sample preservation device. When in use, the device uses an ultra-low temperature refrigerator to control the temperature of the preservation component, so that the preservation component can conveniently store and preserve combustible ice. The space where combustible ice is stored is sealed by the heat insulation component to prevent external hot air from flowing into the preservation component, causing the combustible ice to melt and produce methane gas; through the cooperation of the groove and the sealing strip, the sealing of the outer shell and the inner shell is enhanced to prevent the cold air in the inner shell from flowing out or the hot air from the outside from flowing in; the air in the air storage box is used to pass through the first An exhaust pipe sprays out, thus preventing hot air from outside from flowing into the inner shell, causing the combustible ice to melt and produce a large amount of methane gas; the air pressure state in the outer shell and the air pressure balance box is used to complete the removal of the methane gas in the outer shell, preventing a large amount of methane gas from flowing out when the outer shell is opened. However, when in use, this device can only store combustible ice samples collected from the ocean. If the combustible ice samples are collected and stored in the ocean and then the device is removed from the deep sea, it may cause the internal air pressure balance box to rupture, making the device unable to store the combustible ice samples normally. To this end, we propose a sample storage device for solid mineral geological exploration. Summary of the Invention

[0016] 1. In the present invention, after sampling is completed, the body is recovered and raised. When the device is rising, the pressure of the body is first adjusted to high pressure because it is operating in the deep sea. When the external environment changes from the deep sea to the sea surface, the external pressure is reduced, so that the pressure in the body pushes the regulating valve to rotate, thereby achieving the effect of internal pressure relief. When the pressure is relieved, the pressure between the sealing cover and the body or the collection box is reduced, so that the liquid nitrogen in the sealing cover also starts to relieve pressure through the regulating valve, thus achieving refrigeration of the body and the collection box, and at the same time being able to increase the pressure.

This effectively avoids the situation in which the previous device can only store combustible ice samples collected from the ocean when in use. If the combustible ice samples are collected and stored in the ocean and then the device is taken out of the deep sea, the internal air pressure balance box may rupture, making the device unable to store the combustible ice samples normally. This effectively improves the stability and safety of the device when storing samples. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-11 , the present invention provides a technical solution:

[0032] Example 1:

[0033] A sample storage device for solid mineral geological exploration includes a body 1, an aggregate assembly 4 for collecting combustible ice is provided in the body 1, the aggregate assembly 4 includes a collection box 41 installed in the body 1, an isolation plate 42 is connected between the collection box 41 and the body 1, and a sealing assembly 2 for sealing the material taking port is provided on the body 1 and the collection box 41. When the sample storage device for solid mineral geological exploration is used to sample and store deep-sea combustible ice, the body 1 can be moved to a suitable sampling point, and then the motor 37 in the sampling assembly 3 is started. In this way, the bevel gear 1 38 drives the bevel gear 2 39 to rotate, thereby causing the sampling drill bit 35 to start rotating, and then the motor 2 54 in the adjustment component 5 is started, so that the threaded sleeve 52 rotates and drives the threaded rod 53 to shift through the telescopic outer rod 56 and the telescopic inner rod 57, so that the sample storage device can sample the seabed combustible ice, so that the combustible ice sample is effectively introduced into the collection box 41 in the aggregate component 4 for storage. When the sampling is completed, the body 1 is recovered and raised. When the device is rising, the pressure of the body 1 is reduced. Since it is operated in the deep sea, it is first adjusted to high pressure. When the external environment changes from the deep sea to the sea surface, the external pressure is reduced, so that the pressure in the body 1 pushes the regulating valve 61 to rotate, thereby achieving the effect of internal pressure relief. When the pressure is relieved, the pressure between the sealing cover 21 and the body 1 or the collection box 41 is reduced, so that the liquid nitrogen in the sealing cover 21 also starts to relieve pressure through the regulating valve 61, thus achieving the refrigeration of the body 1 and the collection box 41, and at the same time accelerating the internal pressure reduction efficiency, thereby avoiding the external pressure and the internal pressure difference of the device being too large, causing the body 1 and the collection box 41 to expand and deform, and in severe cases, rupture may occur, resulting in sample loss, thereby effectively avoiding the previous device being able to only store combustible ice samples collected from the ocean when in use. If the combustible ice samples are collected and stored in the ocean and then the device is taken out of the deep sea, the internal air pressure balance box may rupture, causing the device to be unable to store the combustible ice samples normally, thereby effectively improving the stability and safety of the device when storing samples.

[0034] The sealing assembly 2 includes a sealing cover 21 installed on the body 1 or the collection box 41. The sealing cover 21 is provided with a rotor 22 for opening and closing the sealing cover 21. The top of the sealing cover 21 is provided with a nitrogen replenishment port 23, and the bottom of the sealing cover 21 is provided with a nitrogen outlet port 24. The body 1 and the collection box 41 are filled with high-pressure gas or liquid to maintain pressure balance with the deep sea. The sealing cover 21 is hollow inside and filled with liquid nitrogen. When the external pressure changes, the liquid nitrogen is depressurized and replenished.

[0035] The body 1 is provided with a sampling assembly 3 for sampling combustible ice. The sampling assembly 3 includes a connecting pipe 1 31 installed at the feed port of the body 1. The discharge port of the connecting pipe 1 31 is connected to a pump body 32. A connecting pipe 2 33 is installed at the discharge port of the pump body 32. The discharge port of the connecting pipe 2 33 is connected to the feed port of the collection box 41. The pump body 32 is installed on the inner wall of one side of the body 1. The feed port of the connecting pipe 1 31 is rotatably connected to a rotating pipe 34. The outer side of the rotating pipe 34 is movably connected to a sampling drill. The head 35, a support frame 36 for supporting the connecting tube 31 is installed between the connecting tube 31 and the body 1, wherein the rotating tube 34 is rotatably connected to the connecting tube 31, so that when the motor 37 rotates, the rotating tube 34 rotates effectively, thereby realizing the synchronous rotation of the sampling drill bit 35, wherein the pump body 32 adopts a balanced pump, so that when the external sample is extracted into the collection box 41, the phenomenon of the device expanding due to large pressure changes in the device is effectively avoided.

[0036] A motor 37 is installed on the side wall of the support frame 36 away from the connecting pipe 2 33, and a bevel gear 1 38 is installed on the output shaft of the motor 1 37. The outer side of the bevel gear 1 38 is meshedly connected with the bevel gear 2 39, and the bevel gear 2 39 is installed on the outer side of the rotating tube 34. An adjustment component 5 for adjusting the position of the sampling drill bit 35 is provided between the rotating tube 34 and the sampling drill bit 35. When the sampling drill bit 35 samples the sample, it will also bring in seawater and deep-sea mud. Therefore, when the device rises, it is necessary to ensure the internal temperature and pressure, so liquid nitrogen is used for filling. When the liquid nitrogen comes into contact with seawater, it can effectively reduce the temperature of the seawater, thereby effectively avoiding the melting of the internal combustible ice, thereby effectively improving the stability and thermal insulation of the device during use.

[0037] The adjustment assembly 5 includes a fixing frame 51 installed on the connecting pipe 31, and a threaded sleeve 52 is rotatably connected to the fixing frame 51. A threaded rod 53 is spirally connected to the threaded sleeve 52. The fixing frame 51 is fixed to the outside of the connecting pipe 31, so that the position of the threaded sleeve 52 is effectively positioned. When the threaded sleeve 52 rotates, the threaded rod 53 is shifted to drive the position change of the sampling drill bit 35.

[0038] A second motor 54 is mounted on the first fixing frame 51. One end of the threaded sleeve 52 extends to the outside of the first fixing frame 51 and is connected to the output shaft of the second motor 54. The outside of the second motor 54 adopts a high-pressure protective shell, which effectively avoids the influence of deep-sea pressure and seawater, thereby ensuring the normal operation of the second motor 54 when the device is in use, so that the sampling drill bit 35 can rotate effectively.

[0039] A second fixing frame 55 is installed on the sampling drill bit 35, and the other end of the threaded rod 53 is connected to the second fixing frame 55. Telescopic outer rods 56 are installed on both sides of the fixing frame 1 51, and telescopic inner rods 57 are movably connected to the telescopic outer rods 56. The other ends of the telescopic inner rods 57 are connected to the second fixing frame 55, wherein the second fixing frame 55 and the sampling drill bit 35 are connected by bearings, so that the sampling drill bit 35 can effectively rotate and sample through the rotating tube 34. The telescopic outer rod 56 and the telescopic inner rod 57 can effectively position and move the sampling drill bit 35, thereby avoiding the phenomenon of deviation of the sampling drill bit 35 during sampling displacement, and further ensuring the stability of the device during use.

[0040] The liquid discharge port and nitrogen outlet 24 of the body 1 or the collection box 41 are both provided with a pressure relief assembly 6 for deep-sea ascent pressure relief. The pressure relief assembly 6 includes a regulating valve 61 installed on the liquid discharge port and nitrogen outlet 24 of the body 1 or the collection box 41. A valve stem 62 is installed on the regulating valve 61. The regulating valve 61 adopts a hydraulic valve and can be provided with a pressure gauge for monitoring the external and internal pressures, and then connected to an external instrument. In this way, the operator can record the pressure data in real time through the external instrument, thereby facilitating the operator to record the ocean pressure and monitor the pressure change data of the device at the same time.

[0041] The valve stem 62 is connected to a plurality of shift blocks 63 arranged in a circular array, and a mounting bracket 64 is installed on the regulating valve 61. The mounting bracket 64 is provided with through grooves that match the corresponding shift blocks 63. The mounting bracket 64 allows the valve stem 62 to be effectively positioned and moved by the shift blocks 63 when it rotates, thereby avoiding the phenomenon of the valve stem 62 rotating out of position.

[0042] An annular positioning rod 65 is installed on the mounting frame 64, and a through hole is opened on the shift block 63 to match the positioning rod 65. A spring 66 movably connected to the positioning rod 65 is installed between the shift block 63 and the mounting frame 64. The spring 66 can effectively squeeze the shift block 63 to prevent the regulating valve 61 from biasing and leaking sideways, and after the shift block 63 is biased and the pressure is released, the regulating valve 61 can be quickly reset to avoid the backflow of external seawater.

[0043] Example 2:

[0044] like Figure 12As shown, in this second embodiment, the other structures remain unchanged, and the present invention provides another structural form of the pressure relief assembly 6. When the device rises from the deep sea to the sea surface, the internal pressure becomes greater than the external pressure, causing the valve stem 62 of the regulating valve 61 to rotate, thereby causing the shift block 63 to rotate and begin to squeeze the spring 66, thus opening the regulating valve 61 and causing the body 1 and the collection box 41 to begin to relieve pressure. In this second embodiment, to prevent the regulating valve 61 from rotating too much, the shift block 63 rotates to cause the spring 66 to contract, thereby gradually increasing the reaction force of the spring 66, thereby achieving a faster reset of the solid mineral geological exploration sample storage device in the later stage, effectively avoiding the phenomenon of slow reset of the regulating valve 61, which may cause the backflow of external seawater.
