Description

Technical Field

[0001] The present invention belongs to the technical field of sample preservation, and in particular is a natural resource sample preservation device in a field environment. Background Art

[0002] Soil is an important resource on the earth's surface and has a profound impact on agricultural production, ecological balance and global climate change. Currently, research on soil resources mainly focuses on its oxidation process, influencing factors and global climate change. However, in practical applications, how to effectively protect and utilize soil resources and how to optimize their management through technical means are still urgent problems to be solved. Therefore, research on the collection, processing and analysis technology of soil resource samples has important practical significance and application value.

[0003] When preserving soil samples containing organic matter, microorganisms, and iron and aluminum oxides, in order to prevent them from being oxidized, we need to seal and preserve such soils under negative pressure conditions. In the field, users can use a manual vacuum pump to evacuate the preservation box and make it reach a negative pressure state. However, the operator cannot judge the pressure inside the sealed box. If the vacuum degree inside the sealed box is too high, the high vacuum environment will cause water loss in the soil, and then cause the inorganic matter in the soil to deteriorate, which cannot meet people's research needs. In order to solve the above problems, a natural resource sample preservation device in the field environment is proposed. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a natural resource sample preservation device for outdoor environments, which solves the problem of excessive negative pressure in the inner box when a separately carried vacuum device is used to pump air, resulting in water loss in the soil.

[0011] Preferably, the power storage assembly includes a sleeve rod, a spring and a second piston rod movably connected to the interior of the cavity; a limit rod, which is clamped in the interior of the cavity and is used to limit the circumferential position of the second piston rod; a spring, which is movably clamped to the inner wall of the cavity and movably clamped to the outside of the sleeve rod; a connecting column, one end of which is movably clamped to the interior of the sleeve rod and keeps rotating synchronously with the sleeve rod; a bayonet, which is movably connected to the interior of the cavity and passes through the box body upward; wherein the rod body and the piston part of the second piston rod are respectively located in the sleeve rod and the cavity, and the outer sleeve of the bayonet is provided with a piston ring and a sleeve for pulling the bayonet. A tension spring maintains an upward trend, and a slot is provided on the outside of the sleeve rod, and the bayonet is initially inserted into the slot; a spiral groove is provided on the inner wall of the sleeve rod, and one end of the second piston rod is fixedly connected to a protrusion that is inserted into the spiral groove. When the internal pressure of the cavity decreases, the bayonet has a downward trend through the exhaust component fixedly connected to the cavity, and the second piston rod drives the protrusion to move toward the sealing member. The protrusion slides along the spiral groove and forces the sleeve rod to drive the mainspring, the connecting column and the generating component sleeved on the outside of the connecting column to rotate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The above scheme cooperates with the structures such as the pipeline assembly, the storage assembly, the connecting rod and the hook, so that the device can prevent the soil moisture loss caused by excessive negative pressure in the inner box. The supporting block is pushed to move by rotating the connecting rod. At this time, the first piston rod moves toward the spring rod under the tension of the spring rod, and the excess gas in the cavity is discharged to the outside. Then, the connecting rod is rotated in the opposite direction to pull the supporting block to drive the annular groove to move. At this time, the gas inside the inner box and the cavity will be drawn into the cavity through the first one-way valve. The first step is repeated again to discharge the gas inside the cavity. After multiple operations, the gas inside the inner box cannot be drawn out. At this time, the connecting rod is rotated to pull the supporting block to move, which will cause the hook to deform inside the annular groove and detach from the annular groove. At this time, the negative pressure inside the inner box reaches a predetermined range, and at the same time, the negative pressure inside the inner box is prevented from being too large.

[0018] The above scheme cooperates with the structures such as the tooth block, the elastic pick block, the spring and the connecting column. When the inner box leaks due to gas leakage, it has the function of reminding people of the leakage. When the negative pressure inside the inner box is less than the tension of the tension spring outside the bayonet pin, the bayonet pin moves upward and disengages from the slot. At this time, the spring exerts force and drives the tooth block to rotate through the connecting column. The rotation of the tooth block will squeeze the elastic pick block to the side away from the notch. At this time, since the elastic pick block cannot rotate as a whole, it can only force the elastic pick block itself to bend. As the tooth block rotates, the elastic pick block will hit the tooth block and continue to make a sound to remind people that the device is leaking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] like Figures 1 to 12 As shown, the present invention provides a natural resource sample storage device for use in a field environment, comprising a box body 100 and further comprising:

[0034] The storage assembly 200 is placed inside the box body 100;

[0035] The pipe assembly 300 is disposed inside the box body 100;

[0036] The air extraction components 400 are arranged on both sides of the box body 100;

[0037] The power storage assembly 500 is disposed inside the pipeline assembly 300;

[0038] The storage assembly 200 includes an inner box 201 and a sealing cover 202 covering the inner box 201. The inner box 201 and the sealing cover 202 are placed in the box body 100. A filter 203 and a sealing member 204 are provided in the middle of one end of the inner box 201.

[0039] The pipe assembly 300 includes a cavity 301 defined within the box body 100, with a cross pipe 302 fixedly connected thereto. A second one-way valve 304 and a first one-way valve 303 are fixedly connected to the front and rear ends of the cavity 301 and the cross pipe 302, respectively. One end of the cavity 301 is inserted into the inner box 201 and contacts the seal 204.

[0040] The gas inside the cross pipe 302 flows into the cavity 301 in one direction through the first one-way valve 303 , and the gas inside the cavity 301 flows out of the box body 100 in one direction through the second one-way valve 304 ;

[0041] The air extraction assembly 400 includes a connecting rod 401 hinged on both sides of the box body 100, and a first piston rod 402 located at one end of the connecting rod 401 is movably connected inside the box body 100. The first piston rod 402 includes a piston, a rod body, and a spring sleeved on the outside of the rod body, wherein the spring is used to support the piston and the support block 403. Two symmetrical hooks 404 are fixed to the inside of the support block 403. The hook 404 is initially inserted into one of the annular grooves 405 equidistantly provided on the rod body of the first piston rod 402. Two sets of spring rods 406 are elastically connected to the inside of the box body 100. The spring rods 406 are used to pull the first piston rod 402 and make it tend to move toward the spring rods 406;

[0042] When the connecting rod 401 rotates, one end of the connecting rod 401 squeezes the supporting block 403 to move;

[0043] When the first piston rod 402 is moved, the first piston rod 402 is moved toward the first piston rod 406 under the action of the tension of the spring rod 406, and the excess gas in the cavity 301 is discharged to the outside. Then, the connecting rod 401 is rotated in the opposite direction to pull the supporting block 403 to drive the annular groove 405 to move. At this time, the gas inside the inner box 201 and the cavity 301 will be drawn into the cavity 301 through the first one-way valve 303. The first step is repeated again to discharge the gas inside the cavity 301. After multiple operations, the gas inside the inner box 201 cannot be extracted. At this time, the connecting rod 401 is rotated to pull the supporting block 403 to move, which will cause the hook 404 to deform inside the annular groove 405 and disengage from the annular groove 405. At this time, if the operator continues to rotate the connecting rod 401, the first piston rod 402 cannot be moved through the hook 404, and the negative pressure inside the inner box 201 cannot be further increased.

[0044] like Figure 1 、 Figure 6 and Figure 8 As shown, a concave handle is provided on one side of the inner box 201. When the inner box 201 is placed in the box body 100, the sealing member 204 on the other side of the inner box 201 contacts one end of the cross pipe 302.

[0045] With the above solution, when the gas inside the inner box 201 is completely exhausted, the user can take out the inner box 201 through the recessed handle.

[0046] like Figure 1-8 As shown, both ends of the cavity 301 are also connected to the inner cavity of the box body 100 where the first piston rod 402 is located. The two connecting rods 401 are connected by a cross bar and extend upward to the outside of the box body 100. The power arm length of the connecting rod 401 is greater than the resistance arm length.

[0047] A gap larger than the diameter of the first piston rod 402 is left in the resistance arm portion of the connecting rod 401. Straight grooves are provided on both sides of the support block 403. Pins that are fixed to both sides of the resistance arm of the connecting rod 401 and are inserted into the interior of the support block 403 are fixed.

[0048] The cross section of the annular groove 405 is inclined, the middle portion of the hook 404 is concave, and the portion of the hook 404 that is engaged in the annular groove 405 can be bent outward and detached from the annular groove 405;

[0049] By adopting the above scheme, the two connecting rods 401 can be driven to rotate at the same time by rotating the cross bar. At the same time, since the length of the power arm of the connecting rod 401 is greater than the resistance arm, people will save more effort when rotating the connecting rod 401; when the resistance arm of the connecting rod 401 is rotating, the pins at both ends will move downward along the straight groove on the support block 403 until the resistance arm is in a horizontal state; when the negative pressure inside the cavity 301 is too large, the first piston rod 402 cannot be driven to move by the cooperation between the hook 404 and the annular groove 405. At this time, the movement of the support block 403 will cause the hook 404 to bend and disengage from the annular groove 405, thereby avoiding excessive negative pressure inside the cavity 301.

[0050] like Figure 2 、 Figure 8-9 and Figure 11-12 As shown, the power storage assembly 500 includes a sleeve rod 501 movably connected to the interior of the cavity 301 , a mainspring 504 and a second piston rod 502 ;

[0051] A limiting rod 503 is clamped inside the cavity 301 and is used to limit the circumferential position of the second piston rod 502;

[0052] The mainspring 504 is movably connected to the inner wall of the cavity 301 and movably connected to the outside of the sleeve rod 501;

[0053] The connecting column 505 has one end movably engaged with the interior of the sleeve rod 501 and rotates synchronously with the sleeve rod 501;

[0054] The latch 506 is movably connected to the interior of the cavity 301 and extends upward through the box body 100;

[0055] The rod body and piston portion of the second piston rod 502 are located in the sleeve rod 501 and the cavity 301, respectively. The outer portion of the bayonet 506 is provided with a piston ring 5061 and a tension spring for pulling the bayonet 506 to maintain an upward trend. The outer portion of the sleeve rod 501 is provided with a slot 5062, and the bayonet 506 is initially engaged in the slot 5062.

[0056] A spiral groove 5011 is formed on the inner wall of the sleeve rod 501. A protrusion 5021 is fixedly connected to one end of the second piston rod 502 and engages with the spiral groove 5011. When the pressure inside the cavity 301 decreases, the exhaust assembly 700 fixedly connected to the cavity 301 causes the bayonet 506 to move downward, causing the second piston rod 502 to drive the protrusion 5021 toward the sealing member 204. The protrusion 5021 slides along the spiral groove 5011, forcing the sleeve rod 501 to rotate the mainspring 504, the connecting column 505, and the generating assembly 600 sleeved on the outside of the connecting column 505. After the engaging groove 5062 rotates one circle, the bayonet 506 descends and engages with the engaging groove 5062.

[0057] The cross section of the portion of the limiting rod 503 used to limit the second piston rod 502 is hexagonal, and the cross sections of both ends of the connecting column 505 are also hexagonal.

[0058] By adopting the above scheme, when the internal pressure of the inner box 201 gradually decreases, the second piston rod 502 will move toward the inner box 201, and the sleeve rod 501 will drive the connecting column 505 to rotate through the convex column 5021 sliding in the spiral groove 5011, and at the same time the mainspring 504 will accumulate force. When the sleeve rod 501 rotates one circle, the latch pin 506 is subjected to the negative pressure from the inner box 201 through the connecting tube 701 and moves downward and is stuck in the latch slot 5062. At this time, the device reaches a stable state.

[0059] like Figure 1-4 、 Figure 6 and Figure 8-11 As shown, the generating assembly 600 includes a tooth block 601 movably engaged with the outside of the connecting column 505, a T-shaped block 602 movably engaged with the inside of the box body 100 and located above the tooth block 601, an elastic shift block 603 movably engaged with the inside of the T-shaped block 602, and a cover 604 for axially limiting the connecting column 505, the tooth block 601, and the elastic shift block 603 is threadedly connected to one side of the box body 100;

[0060] The bottom of the T-shaped block 602 has a notch. When the mainspring 504 is charged, the rotation of the tooth block 601 can squeeze the elastic block 603 and rotate along the notch. When the mainspring 504 is released, the rotation of the tooth block 601 forces the tooth block 601 to squeeze the bottom of the elastic block 603, producing a sound.

[0061] With the above solution, when the negative pressure inside the inner box 201 is less than the tension of the tension spring outside the bayonet 506, the bayonet 506 moves upward and disengages from the slot 5062. At this time, the mainspring 504 exerts force and drives the tooth block 601 to rotate through the connecting column 505. The rotation of the tooth block 601 will squeeze the elastic pick block 603 to the side away from the notch. At this time, since the elastic pick block 603 cannot rotate as a whole, it can only force the elastic pick block 603 itself to bend. As the tooth block 601 rotates, the elastic pick block 603 will hit the tooth block 601 and continue to make a sound to remind people that the device is leaking.

[0062] like Figure 1 、 Figure 6 、 Figure 8 、 Figure 11 and Figure 12 As shown, the exhaust assembly 700 includes a connecting pipe 701 fixedly connected above the cavity 301;

[0063] A slider 702 movably connected to the top of the box body 100;

[0064] A movable pipe 703 movably connected to the interior of the connecting pipe 701;

[0065] Exhaust slots 704 are arranged in a circumferential array on the connecting pipe 701;

[0066] An exhaust pipe 705 is provided in the box body 100 and is connected to the outside and the exhaust groove 704 respectively;

[0067] The bottom of the slider 702 extends downward through the connecting pipe 701 and is fixedly connected to the movable pipe 703. One side of the slider 702 is inclined. When the slider 702 moves toward the latch 506, the latch 506 is pressed upward and disengaged from the retaining groove 5062. The movable pipe 703 releases the seal on the exhaust groove 704. At this time, external air enters the cavity 301 and the inner box 201 through the exhaust pipe 705 and the connecting pipe 701.

[0068] By adopting the above solution, when people need to take the inner box 201 out of the box body 100, they move the slider 702 to squeeze the latch 506 so that it moves upward and disengages from the slot 5062. At the same time, the slider 702 will also drive the movable pipe 703 to move, and make the exhaust groove 704 connected to the outside world through the exhaust pipe 705. At this time, the outside gas enters the inner box 201 to maintain pressure balance, and then the user can take out the inner box 201 through the recessed handle.

[0069] The working principle and use process of the present invention:

[0070] First, the user can put the soil into the inner box 201, cover it with the sealing cover 202 and put it into the box body 100;

[0071] Then the user can push the support block 403 to move by rotating the connecting rod 401. At this time, the first piston rod 402 moves toward the spring rod 406 under the pulling force of the spring rod 406. At this time, the excess gas in the cavity 301 will be discharged to the outside. Then the user rotates the connecting rod 401 in the opposite direction to pull the support block 403 to move, and drives the annular groove 405 to move through the hook 404. At this time, the gas inside the inner box 201 and the cavity 301 will be drawn into the cavity 301 through the first one-way valve 303. Repeat the first step again to discharge the gas inside the cavity 301. After multiple operations, the gas inside the inner box 201 cannot be extracted. At this time, rotating the connecting rod 401 to pull the support block 403 to move will cause the hook 404 to deform inside the annular groove 405 and disengage from the annular groove 405. At this time, the negative pressure inside the inner box 201 reaches the preset range.

[0072] When the pressure inside the inner box 201 gradually decreases, the second piston rod 502 moves toward the inner box 201 and slides in the spiral groove 5011 via the protruding column 5021, causing the sleeve rod 501 to drive the connecting column 505 to rotate, while simultaneously causing the mainspring 504 to accumulate force. When the sleeve rod 501 rotates one circle, the latch 506 is subjected to the negative pressure from the inner box 201 through the connecting tube 701 and moves downward and engages in the latching groove 5062.

[0073] If the negative pressure inside the inner box 201 is less than the tension of the tension spring outside the bayonet 506, the bayonet 506 moves upward and disengages from the slot 5062. At this time, the mainspring 504 exerts force and drives the tooth block 601 to rotate through the connecting column 505. The rotation of the tooth block 601 will squeeze the elastic pick block 603 to the side away from the notch. At this time, since the elastic pick block 603 cannot rotate as a whole, it can only force the elastic pick block 603 itself to bend. As the tooth block 601 rotates, the elastic pick block 603 will hit the tooth block 601 and continue to make a sound to remind people that the device is leaking.
