[0024] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0025] See Figure 1 and Figure 2 As shown, a positioning device includes a sample bottle base 1, a driving component 2, and a sample bottle tray 3.

[0026] The sample bottle base 1 can be set to be circular, quadrilateral, or polygonal.

[0027] The sample bottle tray 3 is provided with a plurality of sample bottle holders 31 along the circumference. Optionally, the number of sample bottle holders 31 can be set to 5-28. In this embodiment, 24 sample bottle holders 31 are used as an example. The sample bottle holders 31 can be fixed to the sample bottle tray 3 by bolts or can be integrally connected to the sample bottle tray 3. Each sample bottle holder 31 can be used to place a sample bottle.

[0028] The drive unit 2 may include a stepper motor 21.

[0029] The base of the stepper motor 21 is fixed to the sample bottle base 1 by bolts, and the drive shaft of the stepper motor 21 is welded to the rotation center point of the sample bottle tray 3. Through the stepper motor 21, the drive shaft of the stepper motor 21 can drive the sample bottle tray 3 to rotate, so that the sample bottles in the sample bottle holder 31 can be filled with water.

[0030] In this embodiment, a stepper motor 21 is provided on the sample bottle base 1, which drives the sample bottle tray 3 to rotate, making it easy to inject water into the sample bottle in sequence. The operation is simple, the positioning is accurate, and it is not easy to make mistakes.

[0031] See Figure 1 and Figure 2 As shown, it also includes a positioning component 4 disposed on the sample bottle base 1. The positioning component 4 may include a metal sensor 41, a first metal piece 42, a plurality of second metal pieces 43, and a bracket 44.

[0032] The bracket 44 is fixed to the sample bottle base 1 by bolts, and the metal sensor 41 is set on the sample bottle base 1 by the bracket 44. The metal sensor 41 and the bracket 44 are fixed together by bolts.

[0033] The first metal plate 42 is disposed on one of the sample bottle holders 31. As the sample bottle tray 3 rotates, the first metal plate 42 will come into contact with the first contact point of the metal sensor 41 to sense the origin information.

[0034] The second metal plate 43 is respectively disposed on the sample bottle holder 31. The second metal plate 43 can contact the second contact point of the metal sensor 41 during the rotation of the sample bottle tray 3, and is used to count the number of sample bottles.

[0035] In this embodiment, the origin information of the sample bottle can be recorded by the contact between the first metal plate 42 and the metal sensor 41. The number of sample bottles can be counted by the contact between the second metal plate 43 and the metal sensor 41, which facilitates accurate recording of the water content in the sample bottles and makes it easier to inject water into each sample bottle sequentially.

[0036] See Figure 1 and Figure 2 As shown, it also includes a control module, which controls the stepper motor 21 to work based on the origin information and quantity information of the metal sensor 41, so that the stepper motor 21 drives the sample bottle to collect water in sequence. In this embodiment, the control module is not shown.

[0037] The sample bottle base 1 is also equipped with a display screen connected to the metal sensor 41. The display screen can display the origin information and quantity information of the sample bottle. In this embodiment, the display screen is not shown.

[0038] In this embodiment of the application, the control module facilitates automatic control of the water injection operation on the sample bottle, which is simple to operate, accurate in positioning, and highly safe.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] Working principle of this utility model:

[0041] Adjusting the stepper motor 21 causes its drive shaft to rotate the sample bottle tray 3, which in turn moves the sample bottles to the designated position for water collection. As the sample bottle base 1 moves with the tray 3, the first and second contacts of the metal sensor contact the first metal plate 42 and the second metal plate 43, respectively. This information, including origin and quantity, is displayed on the screen. The control module further controls the stepper motor 21 to precisely move the sample bottles to the designated position for water collection.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
