Description

Technical Field

[0001] This utility model relates to the field of sample collection and preservation technology, and in particular to a sample collection and preservation box for marine ecological environment. Background Technology

[0002] In marine ecological environment research, the collection and preservation of samples is crucial. Due to the complexity and variability of marine ecosystems, the collected aquatic biological samples are often very fragile. It is essential to ensure that the biological samples are not damaged during transportation and to maintain their survival status.

[0003] Existing sample collection and preservation technologies mostly employ simple heat preservation measures. However, this method is insufficient to meet the requirements for long-term preservation and maintaining sample activity. For example, Chinese patent disclosure "A sample box for preserving samples collected by air bag" (application number "CN202223438530.3") uses a combination of heating tubes, fans, temperature control units, and power switches to effectively control the temperature inside the box and thus ensure the concentration of the sample. However, it cannot meet the requirements for long-term preservation of biological samples. In the ocean, the journey is long, and it takes a lot of time to transport the collected biological samples to the laboratory, during which the biological samples often die. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a marine ecological environment sample collection and preservation box. Through the cooperation of the heat insulation layer and the cooling device, the temperature inside the container can be kept stable. Since the collection and preservation box is often placed in the environment during sampling, and the temperature is high due to direct sunlight in the ocean, the water temperature in the preservation box will rise. Through the cooperation of the heat insulation layer and the cooling device, the temperature of the container can be maintained and the temperature can be prevented from becoming too high. The internal oscillating blades are driven to rotate by the main shaft, which causes the water to ripple, thereby promoting the entry of oxygen into the water, preventing the biological samples from being hypoxic, and improving the survival rate of the biological samples. The side fan sends outside air into the interior, and the exhaust fan removes carbon dioxide, so that the internal gas is constantly renewed.

[0005] This utility model also provides a marine ecological environment sample collection and preservation box, comprising: a box with a top cover, an insulation layer on the inner wall of the box, a cooling device fixedly connected to the bottom of the box, and a placement basin inside the box; a top plate fixedly connected to the upper surface of the placement basin, a first motor fixedly connected to the upper surface of the top plate, a main shaft fixedly connected to the output end of the first motor, a swivel blade on the main shaft, a protective frame on the side of the main shaft, and an exhaust fan and a blower fan on the top cover. Through the above device, the insulation layer and the cooling device work together to maintain a stable temperature inside the preservation box. The rotation of the swivel blades promotes water ripples, allowing oxygen to enter the interior. The exhaust fan and blower fan continuously replace the internal gas, preventing sample hypoxia and effectively improving the survival rate of biological samples.

[0006] According to the present invention, a marine ecological environment sample collection and preservation box is provided on the side of the box, and the top cover is rotatably connected to the rotating pin. This device, via the rotating pin, allows for easy closing of the top cover and prevents samples from falling out.

[0007] According to the present invention, a marine ecological environment sample collection and preservation box has a handle fixedly connected to the side of the top cover, and the handle is opposite in direction to the pivot pin. This device, with its handle, facilitates opening the top cover, allowing sampling personnel to easily lift the cover and place the sample.

[0008] According to the present invention, a marine ecological environment sample collection and preservation box is provided at the bottom of the box, and the insulation layer and the cooling device are located inside the cooling chamber. Through this device and the cooling chamber, cooling is easily achieved, preventing the temperature of the placed container from becoming too high.

[0009] According to the present invention, a marine ecological environment sample collection and preservation box is provided, wherein the placement basin is located directly above the cooling device, and the side wall of the placement basin is in contact with the insulation layer. Through this device, and via the insulation layer, direct sunlight is blocked from reaching the sample, reducing the damage to biological samples caused by high temperatures.

[0010] According to the present invention, a marine ecological environment sample collection and preservation box includes a swing blade located in the center of the placement basin, a rotator mounted on the main shaft, and the rotator connected to a protective frame. This device, via the rotator, ensures that the protective frame does not rotate while the main shaft rotates, thus preventing damage to the biological samples.

[0011] According to the present invention, a marine ecological environment sample collection and preservation box is provided, wherein the protective frame is located outside the swing blade, and the protective frame is cylindrical in shape. Through this device, the swing blade oscillates the water surface, causing continuous water fluctuations, thereby generating oxygen and improving the survival rate of biological samples.

[0012] According to the marine ecological environment sample collection and preservation box of this utility model, a second motor is fixedly connected to the side surface of the top cover, a blower fan is fixedly connected to the output end of the second motor, a third motor is fixedly connected to the upper surface of the top cover, and an exhaust fan is fixedly connected to the output end of the third motor. Through the above device, the second and third motors promote the flow of internal air.

[0013] Beneficial effects

[0014] Compared with existing technologies, this marine ecological environment sample collection and preservation box maintains a stable temperature inside the container through the combination of an insulation layer and a cooling device. Since the collection and preservation box is often placed in the environment during sampling, and the water temperature in the ocean is high due to direct sunlight, the insulation layer and cooling device help maintain the temperature of the container and prevent overheating. The internal oscillating blades, driven by the main shaft, rotate, causing water ripples and promoting oxygen entry into the water, preventing oxygen deficiency in biological samples and improving their survival rate. A side fan delivers outside air into the box, while an exhaust fan removes carbon dioxide, continuously refreshing the internal atmosphere. Attached Figure Description
