Description

Technical Field

[0001] This invention belongs to the field of ecological observation devices, specifically a low-temperature preservation and storage box for mangrove samples. Background Technology

[0002] Studies on mangrove carbon storage and other related topics require the collection of mangrove vegetation, soil, and microorganism samples for subsequent experiments. Because mangrove research is generally ongoing, these samples need to be refrigerated or frozen for preservation. However, current methods for preserving mangrove samples collected in the field typically involve packing them in resealable bags and storing them in a refrigerator. Therefore, these limitations present some shortcomings in the preservation of field-collected mangrove samples. Summary of the Invention

[0003] Purpose of the invention: To provide a low-temperature preservation storage box for mangrove samples, which is convenient to carry and can be used for low-temperature storage of mangrove samples collected in the field.

[0004] The technical solution of the present invention is as follows: the mangrove sample low-temperature preservation storage box includes: box body, shoulder strap, handle, pulley, refrigeration module, small sample storage room and large sample storage room.

[0005] The shoulder strap is located on the back of the case, the handle is located on the top of the case, and the casters are located on the bottom of the case.

[0006] The refrigeration module, the small sample storage chamber, and the large sample storage chamber are arranged sequentially from top to bottom inside the box.

[0007] The small sample storage chamber is equipped with several flexible cells, which are used to fit the sample.

[0008] The large sample storage chamber includes an elastic mesh for fixing the samples.

[0009] In a further embodiment, the resilient cell is detachably disposed in a small sample storage chamber, and the detachable resilient cell facilitates sampling.

[0010] In a further embodiment, the elastic cell is made of silicone, and the silicone elastic wall of the elastic cell is used to apply an elastic force in the direction of the sample, so that the silicone elastic wall automatically conforms to the sample and reduces sample shaking.

[0011] In a further embodiment, the elastic net is an elastic nylon net with a surface tension adaptable to fix whole seedlings as well as larger packages of soil samples.

[0012] In a further embodiment, the sample storage chamber is installed in the box via a drawer structure.

[0013] The sample storage chamber is equipped with a push-pull switch, which allows for easy opening and closing of the sample storage chamber.

[0014] In a further embodiment, a breathable and waterproof membrane is provided between the refrigeration module and the small sample storage chamber. Since excessive temperature difference can cause cold air to condense into water droplets, which may fall and affect the sample below, an anti-condensation design is added. A breathable and waterproof membrane is used between the cold plate and the storage area to prevent condensation from directly contacting the sample while allowing a small amount of air to circulate.

[0015] In a further embodiment, the cooling module is equipped with a cooling fan, a cooling plate, and a temperature sensor.

[0016] The cooling module is also equipped with a charging interface, which is used to connect DC power to power the cooling fan, cooling plate and temperature sensor. It can be powered by a DC power source compatible with power banks / vehicle power supplies.

[0017] In a further embodiment, the box is also equipped with a battery pack, which powers the cooling fan, the cooling plate and the temperature sensor, so that the storage box can maintain the internal temperature of the storage box even when it is independent for a long time.

[0018] In a further embodiment, the cooling plate is a semiconductor cold plate.

[0019] In a further embodiment, the housing includes an outer layer, a middle layer, and an inner layer arranged from the outside to the inside.

[0020] The outer layer is made of food-grade PP material with an acid and alkali resistant coating.

[0021] The middle layer is made of thermal insulation material.

[0022] The inner layer is made of food-grade silicone, while the outer protective shell is made of food-grade PP material with an acid and alkali resistant coating, providing excellent resistance to impact, seawater (rainwater) immersion, and acid and alkali corrosion. The middle layer incorporates insulation material to reduce cold air loss and extend sample storage time. The food-grade silicone inner layer effectively prevents damage to samples caused by external impacts.

[0023] The beneficial effects of this invention are as follows: This application, through the combination of the box body, shoulder straps, handles, pulleys, and cooling module, makes the box body suitable for carrying on the shoulder in muddy mangrove conditions, and also convenient for pushing on land; through the combination of the cooling module, elastic cells, and elastic net, it can store mangrove samples in layers, classifying and categorizing them to reduce the compression and damage of samples in the box, and also reduce sample shaking, solving the problems of inconvenience in carrying refrigerators in the prior art, and the easy compression and damage of samples inside the refrigerator when it is moved.

Detailed Implementation

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0028] This application discloses a low-temperature preservation storage box for mangrove samples, which can be conveniently carried and stored at low temperatures for storing mangrove samples collected in the field.

[0029] like Figure 1 The storage box includes: box body 12, shoulder strap 1, handle 2, casters 6, cooling module 3, small sample storage chamber 4 and large sample storage chamber 5.

[0030] Shoulder strap 1 is located on the back of case 12, handle 2 is located on the top of case 12, and pulley 6 is located on the bottom of case 12. In a preferred embodiment, shoulder strap 1 is an adjustable shoulder strap 1 filled with pressure-relieving sponge, with a non-slip telescopic handle 2 at the top and a retractable pulley 6 at the bottom.

[0031] The refrigeration module 3, the small sample storage chamber 4, and the large sample storage chamber 5 are arranged sequentially from top to bottom inside the housing 12.

[0032] The small sample storage chamber 4 is equipped with several flexible cells, which are used to fit the sample.

[0033] The large sample storage chamber 5 includes an elastic mesh for fixing the samples.

[0034] In this embodiment, the flexible cell is detachably installed in the small sample storage chamber 4, such as... Figure 1 The diagram shows twelve flexible cells.

[0035] The elastic cell is made of silicone, and the silicone elastic wall of the elastic cell is used to apply an elastic force in the direction of the sample.

[0036] In this embodiment, the elastic mesh is an elastic nylon mesh.

[0037] In this embodiment, the sample storage chamber is installed in the housing 12 via a drawer structure, such as... Figure 1 The two sample storage chambers shown are located on the front of the box 12.

[0038] The sample storage chamber is equipped with a push-pull switch 10.

[0039] In this embodiment, a breathable and waterproof membrane is provided between the refrigeration module 3 and the small sample storage chamber 4.

[0040] like Figure 1 The cooling module 3 shown is equipped with a cooling fan 7, a cooling plate 8, and a temperature sensor 9.

[0041] The cooling module 3 is also equipped with a charging interface, which is used to connect DC power to power the cooling fan 7, the cooling plate 8 and the temperature sensor 9.

[0042] like Figure 1 The housing 12 shown also contains a battery pack 11, which powers the cooling fan 7, the cooling plate 8 and the temperature sensor 9. The battery pack 11 supports 12V output, which can conveniently power the cooling module 3 at any time.

[0043] The cooling plate 8 is a 12V semiconductor cold plate with a power of 50W. It is driven by a DC power supply (compatible with power banks / vehicle power supplies) and can reduce the temperature to as low as 4℃.

[0044] like Figure 2 The box 12 shown includes an outer layer 121, a middle layer 122 and an inner layer 123 arranged from the outside to the inside.

[0045] The outer layer 121 is made of food-grade PP material with an acid and alkali resistant coating.

[0046] The middle layer 122 is made of thermal insulation material.

[0047] The inner layer 123 is made of food-grade silicone.

[0048] The cooling system automatically starts when the internal temperature is >8℃ and stops when it is <4℃, thanks to the cooperation of the cooling fan 7, the cooling plate 8 and the temperature sensor 9. This prevents the samples (especially seedling tissues) from being over-frozen and damaged.

[0049] The core objective of this application is to facilitate the low-temperature preservation of mangrove samples, maintaining a low-temperature environment of 4–8℃ (inhibiting plant cell respiration and enzyme activity, extending sample freshness to 12–24 hours); to store the collected mangrove samples in layers, categories, and zones to avoid the samples being squeezed or damaged in boxes or refrigerators; in addition, due to the muddy nature of the mangrove environment, this design has the advantages of being lightweight, adaptable, waterproof, and resistant to acids and alkalis.

[0050] Before collecting samples, ensure the storage box has sufficient power or bring a spare battery. After collecting mangrove samples, open the corresponding storage room door according to the sample type: place small mangrove samples in the upper storage room and large samples in the lower storage room. After properly placing the samples, close the sliding door, carry the storage box, and continue collecting mangrove samples from other locations. This maintains sampling continuity while ensuring sample viability.
