Description

Technical Field

[0001] The invention relates to the technical field of sample storage, and in particular to an environment monitoring sample storage device. Background Art

[0002] In the process of environmental testing, water quality testing is a very important part. When sampling and testing water quality in areas with very low temperatures, it is necessary to store and keep warm after sampling. Otherwise, the temperature outdoors is too low, which can easily freeze the collected water samples. This will not only affect normal testing in the later stages, but also cause changes in water quality due to temperature differences, leading to errors in the final test results. At the same time, due to the different amounts of samples collected from different areas, the sizes of the collection carriers will also be different. If fewer samples need to be collected, a larger collection carrier will be used. It will not only take up space when carried, but also be inconvenient to limit and fix during storage and carrying when using sampling carriers of different sizes. If they cannot be fixed, collisions will occur during carrying, leading to damage and leakage. Summary of the invention

The cover plate 32 is also provided with a control valve 35, which is connected to the airbag 34 and connected to the barometer 36.

[0054] The specific implementation is as follows: after the collection carrier is loaded, the storage box is sealed by the cover 32. After the storage box is sealed, the cover 32 is locked and fixed by the locking mechanism 33, and is connected to the control valve 35 through an air pump and other equipment, so that air is pumped into the airbag 34, so that the airbag 34 gradually increases. In this way, the airbag 34 can squeeze the collection carrier at the uppermost end, so that the airbag 34 can press and fix the collection carrier to avoid vibration and displacement of the collection carrier during transportation. At the same time, when the airbag 34 squeezes the collection carrier, the pressure of the airbag 34 is monitored by the barometer 36 to avoid excessive inflation of the airbag 34 and damage to the collection carrier.

[0055] In another embodiment provided by the present invention, a sealing groove is provided at the upper end of the side plate 21, and a sealing strip is provided at the lower end of the cover plate 32, and the positions of the sealing groove and the sealing strip correspond to each other;

[0056] The specific implementation is as follows: the cover plate 32 seals the storage box, that is, when each side panel 21 is perpendicular to the cover plate 32, the sealing strip enters the sealing groove. The sealing strip and the sealing groove have three functions: first, the two can effectively seal the side panel 21 and the cover plate 32 to prevent the exchange of cold and hot air, ensure the temperature stability in the box, and improve the insulation effect; second, the two can prevent water vapor or liquid from leaking from inside and outside the storage box, and protect the box body 2 and other equipment from moisture or leakage; third, the sealing strip can reduce the impact when the door is closed, reduce noise, protect the edges of the cover plate 32 and the side panel 21, and extend the service life.

[0057] In another embodiment provided by the present invention, the locking mechanism 33 includes a fixed block 330, a rotating plate 331, a locking rod 332, a first spring 333, a wire rope 334 and a pull rod 335. The fixed block 330 is arranged on the side plate 21 away from the connecting frame 30 in a threaded manner. The rotating plate 331 is rotatably arranged on the fixed block 330. Two locking grooves are arranged on the end of the upper end of the cover plate 32 away from the connecting frame 30. The rotating plate 331 is L-shaped. One end of the rotating plate 331 is movably arranged in the locking groove. Two locking rods 332 are slidably arranged on the rotating plate 331. Locking holes are arranged on both sides of the locking groove. The locking rod 332 is slidably arranged in the locking hole. A first spring 333 is arranged between the two locking rods 332, and a wire rope 334 is also arranged between the two locking rods 332. A pull rod 335 is also slidably arranged on the rotating plate 331, and the wire rope 334 is connected to the pull rod 335.

[0058] The specific implementation is as follows: when the cover 32 seals the storage box, the rotating plate 331 is rotated so that the rotating plate 331 rotates and buckles the cover 32. At this time, the pull rod 335 is pulled so that the two locking rods 332 squeeze the first spring 333 and retract into the rotating plate 331, so that the rotating plate 331 enters the locking groove. After the rotating plate 331 enters the locking groove, the pull rod 335 is released so that the locking rod 332 is reset and enters the locking hole, so that the locking rod 332 and the rotating plate 331 lock and fix the cover 32 on the box body 2. In this way, the cover 32 seals and fixes the collection carrier in the box body 2 to prevent the collection carrier from being thrown out of the storage box during transportation.

[0059] In another embodiment provided by the present invention, the adjustment assembly 4 further includes a limit block 48, a second slider 49 and an adjustment bolt 400.

An adjustment groove is also arranged in the slide groove of the side plate 21, and the second slider 49 is slidably arranged in the adjustment groove. The limit block 48 and the middle part of the second slider 49 are provided with an adjustment bolt 400 in a threaded manner.

[0060] The specific implementation is as follows: the locking of the limit block 48 and the second slider 49 is released by adjusting the bolt 400, so as to adjust the position of the second slider 49 and the limit block 48 in the slide groove, that is, adjust the position of the second slider 49 and the limit block 48 on the side plate 21. After the position adjustment of the two is completed, the limit block 48 and the second slider 49 are locked and fixed on the side plate 21 by adjusting the bolt 400, so that it is convenient for the limit block 48 to limit the second adjustment block 45, so as to adjust the interval between the placement plates 47, so that collection carriers of different sizes can be placed between the placement plates 47.

[0061] In another embodiment provided by the present invention, the upper ends of the first adjustment block 44 and the second adjustment block 45 are both provided with pins, and the side of the placement plate 47 is correspondingly provided with positioning grooves, and the pins are slidably arranged in the positioning grooves, and the width of the first adjustment block 44 is smaller than the width of the second adjustment block 45;

[0062] The specific implementation is as follows: the cooperation between the pin and the positioning groove enables the placement plate 47 to be quickly positioned and placed, and the pin and the positioning groove limit the placement plate 47 to prevent the placement plate 47 from moving or deflecting after the collection carrier is placed. At the same time, the width of the first adjustment block 44 is smaller than the width of the second adjustment block 45, and the width difference between the two is greater than the width of the limit block 48. In this way, the limit block 48 can limit the second adjustment block 45 and allow the first adjustment block 44 to pass, thereby allowing the limit block 48 to adjust the interval between the placement plates 47.

[0063] In another embodiment provided by the present invention, the second adjustment block 45 located on the first adjustment rod 42 includes a block body 450, a guide rod 451, a lifting block 452, a second spring 453 and a threaded plate 454.

[0064] The specific implementation is as follows: when the first adjusting rod 42 drives the second adjusting block 45 located thereon to adjust the position of the placing plate 47, the lower end of the second adjusting block 45 is limited by the limiting block 48 after reaching the position. At this time, when the first adjusting rod 42 continues to rotate to adjust the position of the first adjusting block 44, the first adjusting rod 42 can drive the multiple threaded plates 454 and the lifting block 452 to squeeze the second spring 453 and descend along the guide rod 451, so that the multiple threaded plates 454 extend out of the block 450, and at the same time, each threaded plate 454 can rotate around the lifting block 452, thereby The threaded plates 454 are moved away from the first adjusting rod 42, that is, the threads in the threaded plates 454 are no longer engaged with the threads of the first adjusting rod 42. In this way, the sliding connection between the second adjusting block 45 and the multiple threaded plates 454 and the engagement between the threaded plates 454 and the first adjusting rod 42 are adaptively adjusted to facilitate adjustment of the interval between the first adjusting block 44 and the second adjusting block 45, thereby allowing the first adjusting block 44 and the second adjusting block 45 to adjust the interval between the placement plate 47, so that the placement plate 47 can place collection carriers of different sizes.

[0065] In another embodiment provided by the present invention, the transmission mechanism 41 includes a worm 410, a cross bar 411, a worm wheel 412, a first bevel gear 413 and a second bevel gear 414.

The number of the first bevel gears 413 and the second bevel gears 414 corresponds to each other, and the corresponding first bevel gears 413 are meshed with the second bevel gears 414.

[0066] The specific implementation is as follows: the first adjustment block 44 and the second adjustment block 45 are locked after the first adjustment rod 42 is adjusted in position through the self-locking property of the worm gear 412 and the worm 410. The worm gear 412 and the worm 410 can effectively prevent unnecessary reverse movement, thereby ensuring that the placement plate 47 can remain stable during transportation, and the cross bar 411, the first bevel gear 413 and the second bevel gear 414 drive multiple first adjustment rods 42 to rotate synchronously, thereby synchronously adjusting the position of the first adjustment block 44 and the second adjustment block 45 on the first adjustment rod 42, avoiding the situation where the first adjustment rod 42 is adjusted separately, resulting in inaccurate position of a certain first adjustment block 44 or the second adjustment block 45, resulting in deflection and shaking of the placement plate 47 when placing the collection carrier.

[0067] The placement plate 47 comprises a flat plate, and a plurality of lifting rods are arranged on the upper end of the flat plate, and each lifting rod is connected to the flat plate through a third spring;

[0068] The specific implementation is as follows: a plurality of lifting rods are arranged on the upper end of the flat plate through the third spring, the lifting rods are fitted together, and the stiffness coefficient of the third spring is small, that is, the third spring is slightly squeezed and deformed. In this way, when the collecting carrier is placed on the placement plate 47, the collecting carrier squeezes the lifting rod due to its own gravity, so that the lifting rod squeezes the third spring, and the third spring is squeezed and shortened. In this way, the lifting rod carrying the collecting carrier squeezes the third spring to descend, so that the collecting carrier presses the lifting rod down to form a pit that is completely fitted under it. The pit formed by the lifting rod and the third spring can adaptively support and fix the collecting carrier to avoid slipping of the collecting carrier during transportation.

[0069] Working principle: According to the size of the collection carrier, the four sides of the square block 23 at the lower end of the support rod 20 are screwed with the mounting block 24 as needed, and a plurality of elastic sheets 12 are installed on the bottom plate 10 by means of locking bolts 13. After the elastic sheets 12 are installed, the bottom plate 10 is placed between the four support rods 20 and the mounting blocks 24 are inserted into the four corners of the bottom plate 10. After the mounting blocks 24 and the bottom plate 10 are inserted into each other, the bottom plate 10 is fixed to the mounting blocks 24 by means of fixing bolts 25. After the bottom plate 10 is installed, the side plate 21 is inserted into the mounting groove of the support rod 20 by means of the first slider, so that the bottom plate 10, the side plate 21 and the support rod 20 enclose a accommodating space. After the support rods 20 are assembled, the support plate 11 is placed on the upper end of the elastic sheet 12. At the same time, by increasing the number of support rods 20 and mounting blocks 24, more bottom plates 10 and side plates 21 can be installed, thereby increasing the volume of the storage space surrounded by the bottom plate 10, the side plates 21 and the support rods 20, so that the bottom plate 10, the side plates 21 and the support rods 20 can be loaded with larger collection carriers. In addition, by screwing the connecting frame 30 on the upper ends of two of the support rods 20, a locking mechanism 33 is installed on the upper side of one of the side plates 21, so that the cover plate 32 can rotate around the connecting frame 30 and fit on the upper end of the side plate 21, so that the cover plate 32 can seal the storage space. At the same time, the locking mechanism 33 can lock and fix the cover plate 32 on the side plate 21.

[0070] After the support rod 20, the bottom plate 10, the side plate 21 and the cover plate 32 are assembled into a storage box, the limiting section 51 is rotated so that the limiting section 51 is raised and lowered along the mounting section 50 through the thread, so that the total length between the mounting section 50 and the limiting section 51 including the height of the rubber section 53 is adjusted to be equal to the height of the collection carrier, and at the same time, the mounting section 50 and the limiting section 51 are locked and fixed by the locking nut 52 to prevent the two from being affected by bumps and vibrations during transportation, which may cause the total length of the two to change, thereby causing the collection carrier thereon to be squeezed and damaged. After the total length between the mounting section 50 and the limiting section 51 is adjusted, the limiting rod 5 is installed at the four corners of the upper ends of the support plate 11 and the placement plate 47 through the thread. In this way, when the collection carrier is placed on the support plate 11 and the placement plate 47, the limiting rod 5 can limit the interval between the placement plate 47 and the support plate 11, and between the placement plate 47 and the placement plate 47, so as to prevent the position of the placement plate 47 from changing during transportation and causing the collection carrier to be squeezed and damaged;

[0071] When loading the collecting carrier, first place the collecting carrier on the support plate 11 to place the first layer of collecting carriers, and use foam boards or bubble films to fill the gaps between the collecting carriers and the side plates 21 to prevent the collecting carriers from moving during transportation. After the collecting carriers on the support plate 11 are placed, the placing plate 47 is clamped on the first adjusting block 44 through the pins and the positioning grooves, and then the collecting carriers are placed on the placing plate 47 to place the second layer of collecting carriers. After the second layer of collecting carriers is placed, rotate the rotating rod 40 for only a few turns, and it is not necessary to rotate it all the time, so that the rotating rod 40 drives the cross bar 411 to rotate through the worm 410 and the worm wheel 412, so that the cross bar 411 drives the second bevel gear 414 meshed with it to rotate through the multiple first bevel gears 413, so that the multiple second bevel gears 414 each drive the connected The first adjusting rod 42 rotates synchronously, so that each first adjusting rod 42 drives the first adjusting block 44 and the second adjusting block 45 located thereon to move through threads to adjust the position. At this time, the connecting plate 46 connected to the first adjusting rod 42 drives the connecting plate 46 connected to the second adjusting rod 43 to move synchronously, so that the first adjusting block 44 and the second adjusting block 45 set on the second adjusting rod 43 move synchronously with the connecting plate 46 to adjust the position, and then another placement plate 47 is clamped on the second adjustment block 45 through the pin and the positioning groove. At this time, the collection carrier is placed on the placement plate 47 to place the third layer of collection carrier, and so on. According to the size of the collection carrier and the size of the assembled storage box, by increasing the number and number of layers of the second adjustment block 45 and the placement plate 47, the collection carrier in the storage box can be spaced out into more layers;

[0072] The worm 410 is driven to rotate by rotating the rotating rod 40, so that the worm 410 drives the cross bar 411 to rotate through the worm gear 412, so that the cross bar 411 drives the multiple first bevel gears 413 to rotate synchronously, and then the multiple first bevel gears 413 drive the multiple first adjusting rods 42 to rotate synchronously through the respective meshing second bevel gears 414. When rotating, each first adjusting rod 42 can drive the first adjusting block 44 and the second adjusting block 45 located thereon to descend. In this way, the first adjusting block 44 located on the first adjusting rod 42 drives the lower end of the placement plate 47 connected thereto to squeeze the upper end of the rubber segment 53 installed on the support plate 11, and each second adjusting block 45 drives the lower end of the placement plate 47 connected thereto to squeeze the upper end of the rubber segment 53 installed on the placement plate 47 connected to the first adjusting block 44. The rubber segment 53 limits the placement plate 47 to prevent the placement plate 47 located above from squeezing the collection carrier and causing damage to the collection carrier. At the same time, the rubber segment 53 plays a role of buffering and shock absorbing for the placement plate 47 located above.

[0073] After the collection carrier is placed and adjusted in place, the rotating plate 331 is rotated so that the rotating plate 331 rotates and buckles the cover plate 32, and the pull rod 335 is pulled at the same time, so that the pull rod 335 drives the two locking rods 332 to squeeze the first spring 333 synchronously through the wire rope 334, so that the two locking rods 332 move synchronously into the rotating plate 331, so that the rotating plate 331 enters the locking groove. After the rotating plate 331 enters the locking groove, the pull rod 335 is released, so that the first spring 333 squeezes the locking rod 332 to reset, so that the locking rod 332 is stuck in the locking hole, so that the locking rod 332 and the rotating plate 331 lock and fix the cover plate 32 to the box body. 2, so that the cover plate 32 can seal and fix the collection carrier in the box body 2 to prevent the collection carrier from being thrown out of the storage box during transportation; and after the storage box is sealed, it is connected to the control valve 35 through an air pump (not shown in the figure) and other equipment, so that air is pumped into the airbag 34, so that the airbag 34 gradually increases, so that the airbag 34 can squeeze the collection carrier on the uppermost layer, so that the airbag 34 can press and fix the collection carrier to prevent the collection carrier from vibrating and deviating during transportation. At the same time, when the airbag 34 squeezes the collection carrier, the pressure of the airbag 34 is monitored by the barometer 36 to prevent the airbag 34 from being over-inflated and causing damage to the collection carrier;

[0074] When taking out the collection carrier, first open the control valve 35 to allow part of the gas in the airbag 34 to be discharged, open the cover plate 32, and then take out the collection carrier of the uppermost layer, that is, the third layer. After the collection carrier of the uppermost layer is taken out, rotate the rotating rod 40 in the opposite direction to drive the worm 410 to rotate, so that the worm 410 drives the cross bar 411 to rotate through the worm gear 412, so that the cross bar 411 drives the multiple first bevel gears 413 to rotate synchronously, and the multiple first bevel gears 413 drive the multiple first adjustment rods 42 to rotate synchronously through their respective meshing second bevel gears 414, so that the first adjustment rod 42 can drive each first adjustment block 44 and each second adjustment block 45 to rise along the first adjustment rod 42 when rotating, and when the second adjustment block 45 rises to the top of the slide groove on the inner side of the side plate 21, the multiple threaded plates 454 and the block 4 50 is in the smooth part of the first adjusting rod 42. At this time, multiple threaded plates 454 are disengaged from the threads on the outer side of the first adjusting rod 42, and the second adjusting block 45 and the placement plate 47 stay at the smooth part of the first adjusting rod 42, so it is convenient to remove the placement plate 47 placed on the second adjusting block 45. At the same time, the first adjusting rod 42 in this state can still drive the first adjusting block 44 to continue to rise, so that the first adjusting block 44 drives the placement plate 47 along the second adjusting rod 43 through the connecting plate 46. When the first adjusting rod 42 drives the first adjusting block 44 to rise and fits the lower end of the second adjusting block 45, the collection carrier on the placement plate 47, that is, the second layer of collection carrier, is removed. After the collection carrier is removed, the placement plate 47 is removed, so it is convenient to remove the collection carrier at the bottom layer, that is, the first layer of collection carrier.
