Description

Technical Field

[0001] This utility model relates to the field of groundwater detection, specifically to a sample preservation device for groundwater detection. Background Technology

[0002] After groundwater sampling, it needs to be poured into a bottle for preservation. For example, Chinese patent CN212767719U provides a water sample preservation bottle, which includes an inner and outer glass layer forming the bottle body, a cold storage jacket, and a cap at the bottle mouth; the bottle body and cap are together covered by a removable insulation layer. With preservation bottles like those in the prior art, during testing, the samples inside the bottle need to be poured out in batches for different tests. Due to the long-term storage in the preservation bottle, some impurities settle, leading to significant errors in the test results of different batches of samples, affecting the accuracy of the test data. Utility Model Content

[0003] The purpose of this invention is to provide a sample preservation device for groundwater testing, which solves the problem that in existing preservation bottles, sedimentation easily occurs when samples are stored for a long time, leading to large errors in the test results of samples taken from different batches and affecting the accuracy of the test data.

[0004] To achieve the above objectives, this utility model provides a sample preservation device for groundwater testing. The groundwater sample preservation device includes a storage bottle, an annular support portion formed at the bottom of the storage bottle, a rotating component rotatably disposed at the bottom of the storage bottle, an upper part of the rotating component located inside the storage bottle, a lower part of the rotating component located inside the annular support portion, a stirring rod detachably disposed at the upper part of the rotating component located inside the storage bottle, and a keyway formed on the lower end face of the rotating component.

[0005] Preferably, the bottom of the storage bottle has a hole, the rotating member is rotatably engaged in the hole, and a sealing ring assembly is provided at the contact point between the rotating member and the hole.

[0006] Preferably, the upper end face of the rotating component is formed with a screw hole, and the lower end of the stirring rod is formed with a threaded section that mates with the screw hole.

[0007] Preferably, the storage bottle has a transparent observation window on its side.

[0008] Preferably, a cap is threaded onto the upper opening of the storage bottle.

[0009] Preferably, the groundwater sample preservation device further includes a stirring mechanism;

[0010] The stirring mechanism includes a base, the upper end face of which is formed with a mating groove. A motor is installed inside the base, and the output shaft of the motor extends into the mating groove and is connected to a key that mates with the keyway.

[0011] Preferably, an engaging portion is formed on the outer side of the annular support portion;

[0012] The edge of the mating groove is formed with a locking groove that mates with the locking part.

[0013] Beneficial Effects: This utility model provides a sample preservation device for groundwater testing. The device includes a storage bottle with an annular support at its bottom. A rotating component is rotatably mounted on the bottom of the storage bottle, with its upper part inside the bottle and its lower part inside the annular support. A stirring rod is detachably mounted on the upper part of the rotating component, located inside the storage bottle. A keyway is formed on the lower end face of the rotating component. After groundwater is sampled, it is poured into this storage bottle for storage and transport. Unlike existing storage bottles, this storage bottle has a rotating component at its bottom, with a detachably mounted stirring rod. When the sample needs to be poured for testing, the rotating component can be used externally to drive the stirring rod to rotate and mix the sample, avoiding detection deviations caused by sedimentation, stratification, or adsorption.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] like Figure 1-4 As shown: This utility model provides a sample preservation device for groundwater testing. The groundwater sample preservation device includes a storage bottle 2, with an annular support 26 formed at the bottom of the storage bottle 2. A rotating component 25 is rotatably mounted at the bottom of the storage bottle 2. The upper part of the rotating component 25 is located inside the storage bottle 2, and the lower part of the rotating component 25 is located inside the annular support 26. A stirring rod 24 located inside the storage bottle 2 is detachably mounted on the upper part of the rotating component 25. A keyway 27 is formed on the lower end face of the rotating component 25. After groundwater is sampled, it is poured into this storage bottle for storage and transportation. Unlike storage bottles in the prior art, this storage bottle has a rotating component at the bottom, and a stirring rod is detachably mounted on the rotating component. When it is necessary to pour the sample for testing, the rotating component can be used externally to drive the stirring rod to rotate and mix it, avoiding detection deviations caused by sedimentation, stratification, or adsorption.
