Description

Technical Field

[0001] The invention relates to the technical field of zooplankton sample transport boxes, in particular to a stable zooplankton sample transport box capable of simulating a living environment. Background Art

[0002] Zooplankton is a part of the water ecosystem. They cannot produce organic matter by themselves. They are a group of animals that live in the water. They either have no swimming ability or have weak swimming ability. They cannot move long distances and are not strong enough to resist the flow of water. After the zooplankton in the water is collected, it will be transported to the laboratory for further observation and testing, and then the zooplankton sample transport box will be used;

[0004] A pretreatment device for zooplankton samples disclosed in publication number CN117491117A, when in use, removes a detachable cover plate, and pours the zooplankton sample to be processed into the top filter box. At this time, a water pipe is used to inject water from the top of the filter box into the interior of the filter box, thereby achieving rapid flushing of the sample. During the flushing process of the sample, the filter box is vibrated vertically by the intermittent mutual repulsion of the first drive plate and the second drive plate, and the wastewater is stored in the liquid storage tank and discharged through the drain pipe. The first drive and the second drive cooperate with each other to drive the two adjacent filter boxes to rotate slightly in opposite directions, so that the filter box is moved back and forth horizontally and vertically at the same time, so that the position of the sample in the filter box is continuously changed, and the sample is fully cleaned. In addition, the filter screen is quickly screened by the vertical and horizontal reciprocating movements of the filter box, thereby achieving rapid grading of the sample, and samples of different grades are stored in different filter boxes;

[0005] However, the above scheme still has the following problems during use: when in use, when the zooplankton is inside the box, the box can only carry the zooplankton, which is convenient for moving the zooplankton samples. During transportation, the box is only simply loaded and cannot simulate the living environment of the zooplankton, which makes the mortality rate of zooplankton during transportation higher and the number of samples available for use reduced, thereby affecting the subsequent zooplankton observation experiments and other operations. At the same time, the bumps and shakes generated during transportation can easily cause the transport box to slide, and the stability is weak, which can easily cause bumps.

[0006] Therefore, we proposed a stable transport box for zooplankton samples that can simulate the living environment in order to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide a stable transport box for zooplankton samples that can simulate the living environment, so as to solve the problem of the existing zooplankton sample transport box on the market proposed in the above background technology. When in use, when the zooplankton is inside the box, the box can only carry the zooplankton to facilitate the movement of the zooplankton samples. During the transportation process, the box is only simply loaded and cannot simulate the living environment of the zooplankton, which leads to a higher mortality rate of zooplankton during transportation and a reduction in the number of samples available for use, thereby affecting the later zooplankton observation experiments and other operations. At the same time, the bumps and shaking generated during transportation can easily cause the transport box to slide, and the stability is weak, which can easily cause bumps.

[0015] Preferably, the interior of the rotating rod is configured as a hollow structure, and the rotating rod drives the water-spreading plate to rotate synchronously, and the rotation of the water-spreading plate promotes the flow of water.

[0016] Preferably, the sealing piece outside the air port is set as a rubber piece that is thick in the middle and thin on both sides, and the air port is located at the edge covering the sealing piece, and the air port and the hollow space of the rotating rod are interconnected, and the middle part of the rotating rod is connected to the outlet of the air storage bag through a connecting tube, and the air storage bag is installed on the inner side of the bottom of the box.

[0017] Preferably, the air storage bag is configured as an annular structure, and the input port of the air storage bag passes through the front side of the box body, and a reciprocating screw is provided on the inner side of the bottom of the box body, and the reciprocating screw is integrally provided on the outer side of the bottom of the shaft rod.

[0018] Preferably, a pressure plate is threadedly connected to the reciprocating screw, and the left and right sides of the pressure plate pass through the vertical rod, and the pressure plate forms an extrusion resistance structure between the reciprocating screw and the air bag, and the pressure plate forms an up and down sliding structure through the reciprocating screw and the vertical rod, and the pressure plate is slidably connected to the bottom inner side of the box.

[0019] Preferably, a "U"-shaped scraper is provided at the bottom of the box body, and a shaft is fixed through the middle of the scraper, and a rectangular recess is provided at the top of the shaft, and the recess of the shaft is plugged into the bottom of the plug rod connected to the bearing in the silo outlet, and a round plate is fixedly installed on the top of the plug rod.

[0021] Preferably, the buffer boom is configured as an "L"-shaped structure, and a buffer spring is installed between the top of the buffer boom and the bottom of the box, and the front and rear sides of the buffer boom are symmetrically hinged with a support plate through a torsion spring, and a pull rope is fixed at the hinge of the support plate, and the top of the pull rope is fixedly connected to the bottom of the box.

[0022] Compared with the prior art, the present invention's stable transport box for zooplankton samples that can simulate a living environment has the following advantages: during transportation, it can simulate the living environment of zooplankton, thereby improving the survival rate of zooplankton during transportation, and at the same time, it can maintain the stability of the transport box when bumps and shakes occur during transportation. The specific contents are as follows:

[0023] 1. The setting of the rotating rod and the water-dispensing plate can simulate the state of zooplankton moving when the water flows during transportation. When the large gear rotates, it will drive the small gear on the outside to rotate synchronously, and the small gear will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the rotating rod to rotate synchronously through the sprocket mechanism. When the rotating rod rotates, the water-dispensing plate will rotate, and when the water-dispensing plate rotates, it will stir the water.

[0024] 2. Through the setting of the air vent and the sealing piece, during transportation, the phenomenon of water waves entraining gas into the water body in the living environment of zooplankton can be simulated, thereby increasing the oxygen content. When the gas is ejected, the edge of the sealing piece will be blown up. When the gas stops coming out, the sealing piece will automatically close, thereby sealing the air vent and preventing zooplankton from entering.

[0025] Furthermore, when the shaft rotates, it drives the reciprocating screw to rotate synchronously, and when the reciprocating screw rotates, it drives the pressure plate to move. When the pressure plate moves, it squeezes the air storage bag, and the gas inside the air storage bag is transported to the inside of the rotating rod through the connecting pipe, and then ejected from the air port;

[0026] 3. The arrangement of the circular plate, the first through hole, and the second through hole can simulate the presence of food edible by zooplankton in the water during transportation, making it easier for zooplankton to eat and thus improving the survival rate of zooplankton during transportation. When the shaft rotates, it drives the insertion rod to rotate synchronously, and when the insertion rod rotates, it drives the circular plate on the top to rotate synchronously. The second through hole on the circular plate will intermittently overlap with the first through hole at the silo outlet, thereby allowing the material in the silo to be evenly added to the water inside the box.

[0027] 4. By setting the scraper, the inner wall of the box can be cleaned to avoid the problem of residual dirt and inconvenience in cleaning. After the shaft rotates, it will also drive the scraper to rotate synchronously, and the scraper will clean the inner wall of the box after rotation.

[0028] 5. By setting up the buffer boom and support plate, the box can be kept stable and will not be affected and displaced when bumps occur during transportation. The buffer boom will rotate around the rotation point, thereby compressing the buffer spring and buffering the external force. When the buffer boom rotates, the pull rope will be relaxed, and the torsion spring in the reverse state will drive the support plate to rotate downward, and then support the inner bottom of the car body, thereby further increasing stability. When the buffer boom is reset, the support plate will rotate upward and reset, so that better buffering and stability effect can be achieved by reciprocating to prevent the box from moving.

When in use, the collected zooplankton samples are loaded into the interior of the box body 1 together with the water body, and then the cover 2 is closed. During transportation, the motor 3 in the box body 1 is started, and the motor 3 will drive the shaft rod 4 to rotate.

At the same time, the air storage bag 14 is installed on the inner side of the bottom of the box body 1. When the rotating rod 8 rotates, a gas nozzle will intermittently appear in the air port 10 opened on the outside thereof. When the gas is ejected, the edge of the sealing piece 11 will be blown up. When the gas stops, the sealing piece 11 will automatically close, thereby sealing the air port 10 to prevent zooplankton from entering. In this way, the phenomenon of water waves entraining gas into the water in the living environment of zooplankton can be simulated to increase the oxygen content.
