Description

Technical Field

[0001] This utility model relates to the field of strain identification technology, specifically a sampling device for strain identification. Background Technology

[0002] Strain identification is a crucial step in microbiological research and applications, involving various techniques and methods. It not only contributes to scientific and medical research but is also indispensable in public health, food safety, environmental protection, and industrial production. Accurate identification allows for a better understanding and utilization of microbial resources, contributing to the development of human society. Strain identification often involves sampling water samples.

[0003] However, in current technologies, the presence of various microorganisms in water bodies during water sampling can cause changes in certain physical parameters and chemical components of the water sample during preservation due to changes in environmental conditions, microbial metabolism, and chemical reactions, thus affecting the accuracy of identification. Summary of the Invention

[0004] The purpose of this invention is to provide a sampling device for strain identification, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sampling device for strain identification includes a mounting frame, inside which is a collection component for collecting water samples. The collection component includes an arc-shaped groove on one side of the mounting frame, and the inner wall of the arc-shaped groove is provided with multiple positioning holes. Each of the multiple positioning holes is provided with an extension tube. A connecting rod is provided on the top of the mounting frame.

[0007] A sampling bottle is provided inside the arc-shaped groove. Multiple through grooves are provided on one side of the sampling bottle. The inner walls of the multiple through grooves are provided with holes and sealing rings. Ball bearings are provided inside the holes.

[0008] As a preferred embodiment of this utility model, the mounting frame has a hollow structure inside and communicates with multiple positioning holes. The multiple positioning holes are arrayed on the inner wall of the arc-shaped groove, and one end of the connecting rod is connected to the mounting frame by bolts.

[0009] As a preferred embodiment of this utility model, an air supply pipe is installed inside the connecting rod, and one end of the air supply pipe extends to the outside of the other end of the connecting rod and is connected to an air pump. A control valve is installed at the opening end of each of the multiple extension pipes.

[0010] As a preferred embodiment of this utility model, the sampling bottle is located in the arc-shaped groove and is slidably connected to the inner wall of the arc-shaped groove. The sampling bottle has multiple sample storage spaces arranged in an array inside, and the multiple spaces are distributed in correspondence with multiple through slots. When the sampling bottle is embedded in the arc-shaped groove, the positioning hole on the inner wall of the arc-shaped groove is connected to the through slot on one side of the sampling bottle.

[0011] As a preferred embodiment of this utility model, a control valve is installed on the inner wall of the sample space inside the sampling bottle, the through groove is connected to the sample space inside the sampling bottle, and the ball is located in the slot and rolls within the slot.

[0012] As a preferred embodiment of this utility model, after sampling, the extension tube in the corresponding positioning hole is opened by controlling the sampling bottle, and suction is performed through the gas delivery pipe and pump body to create a vacuum in the corresponding sample space. The suction pressure absorbs the ball, causing the ball to extend from the groove into the sealing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Addressing the problems raised in the background art, this application employs a sampling component. Multiple compartments within the sampling bottle allow for segmented sampling of water at different levels. During sampling, the control valve of the corresponding compartment opens to allow water to enter the sampling bottle. By controlling the opening orifice of the control valve, water slowly enters the sampling bottle while preventing it from filling the entire sample space. Then, a vacuum is created within the sample space through a corresponding extension tube, pump, and gas delivery pipe, removing air from the sample space. The suction pressure causes a ball bearing to extend from the groove and engage with the sealing ring, maintaining a vacuum environment within the sample space. This vacuum environment reduces the biological activity of bacteria in the water, decreases chemical reactions in the water sample, and to a certain extent reduces changes in bacterial strains, thus improving the accuracy of identification.

[0014] This invention enables the collection of water samples to be vacuumed, thereby reducing the activity of bacterial strains in the water sample, inhibiting the bacterial reaction, slowing down the changes in the bacterial reaction, and improving the accuracy of sample identification.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Example

[0021] Please see Figure 1-4 This utility model provides a technical solution: a sampling device for strain identification, including a mounting frame 1. The mounting frame 1 is equipped with a collection component for collecting water samples. The collection component includes an arc-shaped groove 2 on one side of the mounting frame 1 for positioning the sampling bottle 5. The inner wall of the arc-shaped groove 2 is provided with multiple positioning holes 201. When the sampling bottle 5 is installed in the arc-shaped groove 2, the positioning holes 201 are connected to multiple through grooves 6 on the outer wall of the sampling bottle 5. Each of the multiple positioning holes 201 is provided with an extension tube 3. When the positioning hole 201 is connected to the through groove 6, the conical end of the extension tube 3 extends into the through groove 6. The top of the mounting frame 1 is provided with a connecting rod 4, which extends to the outside of the water body, making it easy to insert the mounting frame 1 and the sampling bottle 5 into the water body. The air supply pipe in the connecting rod 4 can cooperate with an air pump to draw air into the mounting frame 1. The control valve of the extension tube 3 can be used to evacuate the corresponding sample chamber in the sampling bottle 5.

[0022] The arc-shaped groove 2 houses a sampling bottle 5 for water sampling. Control valves on the outside of the sampling bottle 5, corresponding to sample chambers at different heights, control the opening and closing of the sample chambers, allowing water to flow into them. Multiple through-slots 6 are provided on one side of the sampling bottle 5, connecting the sample chamber to the extension tube 3. The inner walls of each through-slot 6 are provided with perforations 601 and sealing rings 7. The perforations 601 position the ball bearing 602 under normal conditions, while the sealing rings 7 prevent the ball bearing 602 from detaching from the through-slots 6. The ball bearing 602 is located inside the perforations 601. During vacuuming of the sample chamber, the suction pressure guides the ball bearing 602 out of the perforations 601 and draws it into the sealing ring 7, thus sealing the sample chamber after vacuuming. This vacuum environment reduces the biological activity of bacteria in the water and decreases chemical reactions in the water sample, keeping the bacterial strains in the water sample stable and reducing changes in the strains, thereby improving the accuracy of strain identification.

[0023] In this embodiment, all electrical components are controlled by a conventional controller.

[0024] For an example, please refer to... Figure 1-4The mounting frame 1 has a hollow internal structure and communicates with multiple positioning holes 201. These positioning holes 201 are arrayed on the inner wall of the arc-shaped groove 2. One end of the connecting rod 4 is connected to the mounting frame 1 by bolts. A gas supply pipe is installed inside the connecting rod 4, with one end extending to the outside of the other end of the connecting rod 4 and connected to an air pump. Control valves are installed at the openings of multiple extension pipes 3. The sampling bottle 5 is located within the arc-shaped groove 2 and is slidably connected to the inner wall of the arc-shaped groove 2. The sampling bottle 5 has multiple sample storage spaces arrayed inside, and these spaces correspond to multiple through slots 6. When the sample bottle 5 is embedded in the arc-shaped groove 2, the positioning hole 201 on the inner wall of the arc-shaped groove 2 is connected to the through groove 6 on one side of the sampling bottle 5. A control valve is installed on the inner wall of the sample space inside the sampling bottle 5. The through groove 6 is connected to the sample space inside the sampling bottle 5. The ball bearing 602 is located in the hole groove 601 and rolls in the hole groove 601. After the sampling bottle 5 samples, the extension tube 3 in the corresponding positioning hole 201 is opened. The gas supply pipe and the pump body are used to draw a vacuum in the corresponding sample space. The suction pressure absorbs the ball bearing 602, causing the ball bearing 602 to extend from the hole groove 601 into the sealing ring 7. In use, the sampling bottle 5 is first installed in the arc-shaped groove 2. Then, the mounting frame 1 and the sampling bottle 5 are inserted into the water body through the connecting rod 4. When the water body reaches the specified depth, the control valve in the sample chamber at the corresponding position in the sampling bottle 5 is opened to allow water to slowly enter the sample chamber without filling it completely for sampling. Then, the valve of the sample chamber is closed and the control valve of the extension tube 3 at the corresponding position is opened. The air pump is controlled to run in conjunction with the air supply pipe to draw air from the mounting frame 1. At the same time, the sample chamber is evacuated through the extension tube 3 and the through groove 6. During the evacuation process, the suction pressure drives the ball bearing 602 to extend out of the hole groove 601 and embed into the sealing ring 7 to maintain a vacuum environment in the sample chamber.

[0025] The working process of this utility model is as follows: First, the sampling bottle 5 is installed in the arc-shaped groove 2. Then, the mounting frame 1 and the sampling bottle 5 are inserted into the water body via the connecting rod 4. When the sample reaches the designated depth, the control valve in the corresponding sample chamber of the sampling bottle 5 is opened, allowing water to slowly enter the sample chamber without filling it completely. Then, the valve in the sample chamber is closed, and the control valve of the corresponding extension tube 3 is opened. The air pump is then operated in conjunction with the air delivery pipe to evacuate air from the mounting frame 1. Simultaneously, a vacuum is created in the sample chamber through the extension tube 3 and the through groove 6. During the vacuuming process, the suction pressure drives the ball bearing 602 to extend from the slot 601 and embed into the sealing ring 7, maintaining a vacuum environment in the sample chamber. This utility model achieves vacuuming of the collected water sample. The vacuum environment reduces the activity of bacterial strains in the water sample, inhibits bacterial reactions, slows down bacterial changes, and improves the accuracy of sample identification.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
