[0001] This utility model relates to the field of water sample storage technology, and in particular to a sample storage device for water environment testing. Background Technology

[0002] The water environment testing sample storage device is mainly used to store and preserve the collected water samples during the water environment testing process. Depending on the situation, the water environment testing sample storage device can be placed on the table of the collection vessel or put into a storage cabinet. After the collection vessel docks, the water environment testing sample storage device can be transferred to the laboratory for water environment analysis. Laboratory personnel can use a pipette to absorb the test water in the water environment testing sample storage device and observe it under a microscope.

[0003] Existing water environment testing sample storage devices typically use test tubes for storage. After the test tubes are inserted into test tube racks, they are placed in storage cabinets. However, the tops of the test tubes lack effective anti-spillage devices, and the collection vessel is prone to swaying during navigation, which can easily cause leakage of the test water. In addition, the test tubes lack uprighting devices, making it difficult to place them on a table temporarily. Utility Model Content

[0004] To overcome the problem that existing water environment testing sample storage devices lack effective anti-spillage devices, cannot reduce the splashing of test water, and the test tubes themselves are difficult to stand temporarily on the table.

[0005] The technical solution of this utility model is as follows: a sample storage device for water environment testing, including a base frame, a sample tube inserted above the base frame, the sample tube including an anti-tipping part to prevent it from tipping over for a long time, the anti-tipping part including a hemispherical shell, a counterweight attached to the lower part inside the hemispherical shell, a tube body on the top of the hemispherical shell, the tube body including a cavity capable of containing the water to be tested, a stopper cap on the top of the tube body, a flexible plug that is interference-fitted with the cavity at the bottom of the stopper cap, a groove on the top of the stopper cap, a circular hole penetrating the stopper cap and the plug at the bottom of the groove, the diameter of the groove being larger than the diameter of the circular hole, a rubber pad attached to the bottom of the groove corresponding to the top of the circular hole, the top center of the rubber pad being pierced by a needle tip.

[0006] Preferably, a number of limiting tubes are provided on the top of the base frame. Each limiting tube includes a receiving cavity that is recessed from the top downwards. A hemispherical shell that can hold a sample tube is placed inside the receiving cavity. The hemispherical shell is fitted with a clearance within the receiving cavity.

[0008] Preferably, the length of the left and right sides of the base frame is greater than the length of the front and rear sides of the base frame, and the left and right sides of the base frame are provided with notches that connect to the bottom of the base frame.

[0009] Preferably, the bottom of the base frame has upwardly recessed clearance grooves on the front and rear sides, and magnets are installed in the clearance grooves. The distance between the left and right sides of the magnets is greater than the distance between the front and rear sides of the magnets.

[0010] Preferably, the base frame is made of metal, the surface of the base frame is coated with rust-proof paint, and the top of the base frame has a through hole running from top to bottom.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5 This utility model provides an embodiment: a sample storage device for water environment testing, including a base frame 1, a sample tube 4 inserted above the base frame 1, the sample tube 4 including an anti-tipping part to prevent prolonged tipping, the anti-tipping part including a hemispherical shell 43, a counterweight attached to the lower part inside the hemispherical shell 43, a tube body 42 at the top of the hemispherical shell 43, the tube body 42 including a cavity 420 capable of accommodating the test water, a stopper cap 41 at the top of the tube body 42, a stopper 44 elastically fitted with the cavity 420 at the bottom of the stopper cap 41, and a stopper 44 elastically fitted with the cavity 420 at the top of the stopper cap 41. The sample tube 4 has a groove 410, the bottom of which has a circular hole 440 penetrating the plug 41 and the plug 44. The diameter of the groove 410 is larger than the diameter of the circular hole 440. A rubber pad 411 is attached to the bottom of the groove 410 corresponding to the top of the circular hole 440. The top center of the rubber pad 411 is pierced by a needle tip. The counterweight inside the hemispherical shell 43 causes the center of gravity of the sample tube 4 to shift downward, so that the sample tube 4 containing the test water can be corrected again after being tilted, giving the sample tube 4 a temporary standing function. The rubber pad 411 can shield the test water in the tube cavity 420. To prevent sample tube 4 from splashing out due to vibration during transportation, a rubber pad 411 pierced by a needle tip provides a certain degree of protection against leakage and balances the air pressure between the tube cavity 420 and the outside environment, preventing the cap 41 from being difficult to remove. Several limiting tubes 3 are provided at the top of the base frame 1. Each limiting tube 3 includes a recessed receiving cavity 30, within which a hemispherical shell 43 of the sample tube 4 can be placed. The hemispherical shell 43 fits with the receiving cavity 30 with a clearance. The limiting tubes 3 restrict the position of the sample tube 4 relative to the base frame 1. To reduce the offset of sample tube 4, the top area of ​​the base frame 1 is smaller than the bottom area of ​​the base frame 1, and the center of the top of the base frame 1 coincides with the center of the bottom of the base frame 1. By making the top area of ​​the base frame 1 smaller than the bottom area of ​​the base frame 1, the stability of the base frame 1 is increased, preventing the base frame 1 from tipping over due to shaking on the testing vessel. The length of the left and right sides of the base frame 1 is greater than the length of the front and rear sides of the base frame 1. The left and right sides of the base frame 1 are provided with notches 11 that connect to the bottom of the base frame 1. The notches 11 make it easy to pry up the base frame 1 when it is attached to the table, reducing the force required.

[0022] Please see Figure 2 - Figure 5In this embodiment, the bottom of the base frame 1 has upwardly recessed clearance grooves 120 on both the front and rear sides. Magnets 12 are installed within the clearance grooves 120. The distance between the left and right sides of the magnets 12 is greater than the distance between the front and rear sides of the magnets 12. Strong adhesive is used to bond the magnets 12 within the clearance grooves 120, resulting in stronger adsorption when placed on a metal tabletop, increasing the stability of the base frame 1 on the table. The base frame 1 is made of metal and coated with rust-proof paint. A through-hole 13 is provided at the top of the base frame 1. The metal construction of the base frame 1 increases its durability, and the rust-proof paint effectively prevents rusting. A groove is provided at the bottom of the hemispherical shell 43, containing a magnet. The magnet can cause the hemispherical shell 43 to adhere to the top of the base frame 1. The through-hole 13 is located at the top of the base frame 1 within the receiving cavity 30, allowing water splashed into the receiving cavity 30 to flow into the through-hole 13. The front and rear sidewalls of the base frame 1 are affixed with... A label holder 2, made of transparent acrylic sheet, is used to hold the numbered papers. This allows users to clearly see the corresponding numbers of the different limit tubes 3. Label holders 2 are attached to both sides for easy observation from both the front and back of the base frame 1. An insertion compartment 20 is located at the bottom of the label holder 2. A baffle 21 protrudes from the side of the bottom of the label holder 2 facing the base frame 1. The distance between the left and right sides of the baffle 21 is less than the distance between the left and right sides of the insertion compartment 20. When the baffle 21 is attached to the base frame 1, it does not completely block the front and back sides of the insertion compartment 20. By placing the insertion compartment 20 at the bottom of the label holder 2, water can be effectively prevented from entering the insertion compartment 20. At the same time, the baffle 21 does not obstruct the paper with the numbered paper from being placed in the insertion compartment 20 and also prevents the paper with the numbered paper from falling out.

[0023] During the operation, the water environment sampling personnel navigate the sampling vessel to the area where water environment testing is required. At the designated sampling point, the vessel stops, and the sample tube 4 on the base frame 1 is pulled out from the receiving cavity 30 of the limiting tube 3. The stopper 44 of the sample tube 4 is then removed from the cavity 420 of the tube body 42. The cap 41 is then placed into the corresponding receiving cavity 30. A certain amount of water for testing is then drawn from the water area using a dropper and discharged into the cavity 420. The height of the water for testing within the tube body 42 should not exceed half the height of the tube body 42. When the collector is temporarily unavailable, the sample tube 4 can be placed on the table. The counterweight inside the hemispherical shell 43 ensures that the sample tube 4 maintains a certain balance and does not tip over. When the table is made of iron, the magnet at the bottom of the hemispherical shell 43 can attract the table, making the sample tube 4 more stable. When the collector pinches the stopper cap 41 and inserts the stopper 44 back into the cavity 420 of the tube body 42, the gas in the cavity 420 can be discharged from the crack in the rubber pad 411 punctured by the needle tip. When there is water in the receiving cavity 30, the water can be discharged from the drain hole 13 to the base frame 1. At the bottom, the magnet 12 protrudes slightly downwards from the bottom of the base 1, facilitating the drainage of accumulated water. The magnet 12 can adhere to the iron tabletop, increasing the stability of the base 1. Simultaneously, the magnet at the bottom of the hemispherical shell 43 can adhere to the top of the base 1. When the base 1 needs to be moved, a pen or other stick-like object can be inserted into the notch 11, and then the side away from the notch 11 can be lifted to easily detach the magnet 12 from the iron tabletop. When the water environment testing sample storage device is placed in a refrigerated storage cabinet, the gas in the cavity 420... The device is compressed and can be easily opened again thanks to the crack in the rubber pad 411. This water environment testing sample storage device is suitable for storing test water for detecting inorganic substances and non-volatile substances. The principle that the hemispherical shell 43 of the sample tube 4 will not tip over under the action of the counterweight is similar to the principle of a roly-poly toy. When it is necessary to place a piece of paper with a number written on it in the label shell 2, insert the paper into the insertion chamber 20 at the bottom of the label shell 2, and then bring the paper closer to the middle of the base frame 1 so that the baffle 21 supports the bottom of the paper.

[0024] Through the above steps, the counterweight inside the hemispherical shell 43 shifts the center of gravity of the sample tube 4 downward, allowing the sample tube 4 containing the test water to correct its position after tipping over, thus enabling the sample tube 4 to stand temporarily. The rubber pad 411 can shield the test water in the tube cavity 420, reducing the splashing of test water due to vibration during transportation. This solves the problem that existing water environment testing sample storage devices lack effective anti-spillage devices, cannot reduce the splashing of test water, and the test tube itself is difficult to stand temporarily on the table.
