Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, specifically a water body sampling and storage device for aquaculture water body testing. Background Technology

[0002] Aquaculture is one of the aquaculture industries. In order to improve the yield and quality of aquatic products, aquaculture requires the sampling of water samples, which are then stored.

[0003] Existing water sample storage methods are not conducive to storing water samples from different water bodies or different locations within the same water body. This makes it easy for samples to mix together after sampling, requiring re-verification during subsequent testing and resulting in longer testing times. In addition, when retrieving samples, the hands of testing personnel are likely to come into contact with the samples, causing hand and sample contamination, and the overall ease of use is poor.

[0004] Therefore, those skilled in the art have provided a water sampling and storage device for aquaculture water testing to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a water sample collection and storage device for aquaculture water testing, in order to solve the problems mentioned in the background art, such as the difficulty in separating water samples during storage and the potential for bidirectional contamination when retrieving samples.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A water sampling and storage device for aquaculture water testing includes: a storage rack, with fixing holes at each of the four corners of the storage rack, and an elastic soft rubber sheet fixedly installed at the bottom of the fixing holes; a sample container is fitted inside the fixing holes; an inlet is integrally provided at the top of the sample container, and an outer cylinder is installed at the upper end of the inlet; a push rod is installed inside the outer cylinder, and a pressure rod is fixedly connected to the upper end of the push rod; a piston is provided at the lower end of the push rod; and a liquid outlet is fixedly connected to the lower end of the sample container, with a sealing cap threaded onto the lower end of the liquid outlet.

[0008] As a further improvement of this utility model: the internal structural dimensions of the fixing hole match the external structural dimensions of the sample container, and the external shape of the sample container is a cubic prism.

[0009] As a further improvement of this utility model: the upper inlet of the sample container is connected to the outer cylinder by a threaded connection, and the inlet is connected to the liquid outlet.

[0010] As a further improvement of this utility model: the middle part of the storage rack is connected to a connector, and the two ends of the connector are provided with fixing nails.

[0011] As a further improvement of this utility model: the connector is fixedly connected to the storage rack by a fixing nail, and the storage rack is symmetrical about the center line of the connector.

[0012] As a further improvement of this utility model: a handle is fixedly connected to the outside of the storage rack, and a viewing window is provided on the surface of the sample container.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Sample containers are stored separately using a storage rack. Each of the four corners of the storage rack has a fixing hole. The sample container is placed in the fixing hole, and the external structure of the sample container matches the internal structure of the fixing hole. An elastic soft rubber sheet is placed inside the fixing hole. The elastic tension of the soft rubber sheet is used to fix the sample container, increasing the friction between the bottom of the fixing hole and the sample container, thereby improving the stability of the sample container storage.

[0015] 2. The inlet of the sample container is connected to the outer cylinder by a thread. After the outer cylinder is connected to the inlet, the push rod and piston inside the outer cylinder are used. The push rod and the pressure rod are connected to each other, and then the piston discharges the sample stored inside the sample container. During the whole process, the testing personnel will not come into contact with the sample. In this way, the sample will not come into contact with the hands and the sample will not be contaminated, thus avoiding two-way contamination and making the sampling process more convenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a water body sampling and storage device for aquaculture water testing, including: a storage rack 1, with fixing holes 2 at each of the four corners of the storage rack 1, and an elastic soft rubber sheet 7 fixedly installed at the bottom of the fixing holes 2, a sample container 3 being fitted inside the fixing holes 2, an inlet 31 being integrally provided at the top of the sample container 3, and an outer cylinder 10 being installed at the upper end of the inlet 31, a push rod 12 being installed inside the outer cylinder 10, and a pressure rod 11 being fixedly connected to the upper end of the push rod 12, and a piston 13 being provided at the lower end of the push rod 12, and a liquid outlet 8 being fixedly connected to the lower end of the sample container 3, and a sealing cap 9 being threadedly fitted at the lower end of the liquid outlet 8.

[0023] The internal structural dimensions of the fixing hole 2 match the external structural dimensions of the sample container 3, and the external shape of the sample container 3 is a cubic column. The upper inlet 31 of the sample container 3 is connected to the outer cylinder 10 by a thread, and the inlet 31 is connected to the liquid outlet 8. The outer side of the storage rack 1 is fixedly connected with a handle 6, and the surface of the sample container 3 is provided with a viewing window 14.

[0024] Specifically, the sample container 3 is designed as a cubic cylindrical structure, and the cubic shape matches the structure of the fixing hole 2. This provides a better positioning effect between the square and the circle, preventing the sample container 3 from sliding inside the fixing hole 2. The top opening of the sample container 3 is used for sample injection, and the bottom outlet 8 is used for sample discharge. The viewing window 14 allows observation of the inside of the sample container 3, enabling observation of whether the sample is full or empty.

[0025] The middle part of the storage rack 1 is connected to the connector 4, and the two ends of the connector 4 are provided with fixing nails 5. The connector 4 is fixedly connected to the storage rack 1 through the fixing nails 5, and the storage rack 1 is symmetrical about the center line of the connector 4.

[0026] Specifically, by setting the connector 4, the two groups of storage racks 1 are connected together to form a complete storage rack 1 structure. After assembly, the four corners of the storage rack 1 can store four groups of samples separately, which is conducive to storing samples extracted from different water areas and different locations in the same water area separately, avoiding sample confusion and contamination.

[0027] When using this invention, the extracted water sample is stored in the sample container 3. The inlet 31 of the sample container 3 is sealed by the threaded connection between the inlet 31 and the outer cylinder 10. Sample containers 3 from different water bodies and different locations within the same water body are placed at the four corners of the storage rack 1. The sample container 3 is inserted vertically through the fixing hole 2. During insertion, the elastic soft rubber sheet 7 is stretched open. The elastic tension of the elastic soft rubber sheet 7 is used to position the sample container 3 and increase the friction between it and the sample container 3, thereby stabilizing the sample container 3. Next, when the sample is removed, the push rod 12 and the pressure rod 11 inside the outer cylinder 10 are connected to each other. Pressing down the pressure rod 11 and the push rod 12 causes the piston 13 to discharge the sample inside the sample container 3. The piston 13 pushes the sample inside the sample container 3, and the water sample is discharged from the outlet 8. During the sample removal and testing process, contact with the sample is avoided to prevent bidirectional contamination. When the sample container 3 is emptied, the evacuation window 14 is used to observe whether the sample has been emptied.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
