Description

Technical Field

[0001] This utility model belongs to the technical field of probiotic sampling devices, specifically a special device for sampling probiotics at different growth stages of sea cucumbers. Background Technology

[0002] The probiotics (such as Lactobacillus and Bacillus) in sea cucumbers are directly related to their disease resistance, growth rate, and quality (such as collagen content). By studying the probiotic community structure at different growth stages (juvenile, young, and adult sea cucumbers), targeted probiotic preparations can be developed (such as adding them to feed), reducing antibiotic use and improving survival rates and economic benefits in aquaculture. This is a core demand of the industry.

[0003] Meanwhile, a multifunctional probiotic fermentation sampling device with application number CN202521578376.0 includes a collection mechanism, a sampling mechanism above the collection mechanism, and a shelf. The sampling mechanism includes a support plate placed inside the shelf. Handles are fixedly connected to both sides of the support plate. Several placement slots are also opened on the top surface of the support plate. Each placement slot is equidistant along the length of the support plate. A splash guard is fixedly connected to the top surface of the support plate and outside each placement slot. A sampling cup is inserted into the inside of each placement slot. The top opening of the sampling cup is located below the top surface of the splash guard.

[0004] However, the following problems were found in the implementation of the relevant technology: the existing equipment and tools are poorly managed and have poor stage adaptability. Tools at different growth stages are mixed in the same container. When a tool is used, the lid must be opened as a whole. All tools are exposed to the water and air bacteria in the breeding pond, resulting in serious tool exposure and cross-contamination.

[0005] To this end, we propose a special device for sampling probiotics at different growth stages of sea cucumbers. Utility Model Content

It includes a workbench 1, with a larval sampling module 2 and a juvenile sea cucumber sampling module 3 fixedly connected to the upper surface of the workbench 1. The larval sampling module 2 uses a nylon mesh to form a funnel-shaped sampling head, paired with a collection tube. The edge of the mesh is wrapped with a soft silicone ring to avoid scratching the inner wall of the aquaculture container. The sampling head is connected to a negative pressure micro-adjustment pump. By adjusting the negative pressure intensity, it achieves gentle collection of suspended sea cucumber eggs and larvae in the water, while filtering out impurities to ensure the integrity of the probiotic carrier in the sample. The juvenile sea cucumber sampling module 3 is an integrated structure, with a circular adsorption plate covered with a breathable sponge. It is fixed to the mesh or pool wall where the juvenile sea cucumbers are attached by negative pressure adsorption. The edge of the adsorption plate is equipped with a retractable stainless steel micro-scraper. The scraping force is adjusted by a knob, and after gently separating the juvenile sea cucumbers, the scraping is collected from the collection trough below the adsorption plate. The inner wall of the collection tank is coated with an anti-stick coating to prevent young samples from sticking together. A sample collection module 4 is fixedly connected to the upper surface of the workbench 1. The sample collection module 4 includes a support base 5. An installation plate 6 is fixedly connected to the inner surface of the support base 5. A spring 7 is fixedly connected to the outer surface of the installation plate 6. An elastic plate 8 is fixedly connected to the other end of the spring 7. A sterilization box 9 is fixedly connected to the upper surface of the sterilization box 9. A box body 10 is fixedly connected to the upper surface of the box body 10. A partition 11 is fixedly connected to the inner surface of the box body 10. The partition 11 divides the box body 10 into several sterile chambers for placing different sampling tools. Each sterile chamber is provided with a cover plate 14. A sealing layer is provided on the cover plate 14. A press buckle 12 and a magnet block 13 are provided on the cover plate 14 and the box body 10. The press buckle 12 is pressed once to lock the position of the cover body 14. Pressing it again releases the cover body 14.

[0024] Specifically, the support base 5 has a slot, and the mounting plate 6 is located in the slot.

[0025] Furthermore, an elastic column 17 is fixedly connected to the outer surface of the mounting plate 6, and the other end of the elastic column 17 is fixedly connected to the elastic plate 8 to ensure the linear movement of the elastic plate 8 and prevent the spring 7 from tilting.

[0026] Furthermore, a silicone layer is fixedly connected to the outer surface of the elastic plate 8.

[0027] It is worth noting that the press buckle 12 is located in the middle of the cover plate 14, and the magnet block 13 is located on both sides of the cover plate 14.

[0028] It is worth noting that the cover plate 14 and the box body 10 are provided with a recessed groove, and the magnet block 13 is located in the recessed groove.

[0029] It is worth mentioning that a label box 15 is fixedly connected to the upper surface of the cover plate 14. The label box contains iron labels used to restrict the name of the sampling tool.

[0030] Among them, the larval sampling module 2, the juvenile sample sampling module 3, the disinfection box 9, and the pressing buckle 12 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0031] Working principle: During use, the nylon screen in the larval sampling module 2 forms a funnel-shaped sampling head to sample the larvae. The juvenile sea cucumber sampling module 3 uses an integrated structure of adsorption and scraping to sample the juvenile sea cucumbers. When sampling adult sea cucumbers, the adult sea cucumbers are placed between two elastic plates 8. The spring 7 applies elastic force to the elastic plates 8 to fix the adult sea cucumbers. At the same time, the elasticity of the spring 7 and the silicone layer on the elastic plates 8 may damage the adult sea cucumbers. Then, by pressing the cover plate 14 of the corresponding box 10, the tool inside can be taken out for sampling. After using the sampling tool, it is first disinfected in the disinfection box 9. After disinfection, the tool is placed in the corresponding box 10. Multiple boxes 10 are separated by partitions 11. Then, the corresponding cover plate 14 is pressed. The cover plate 14 is locked by the pressing buckle 12 and magnetically fixed by the magnet block 13 to ensure sealing and stability. The box 10 protects the tool in a sterile state.
