[0026] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0027] according to Figure 1-Figure 7As shown, the water quality sampling device provided in this embodiment includes a box body 2 and a door panel 1. The interior of the box body 2 is divided into an upper and lower layer by a partition. A water pump 3 is installed in the upper layer, which is mainly used to pump external water into the sample tube 7. The sample tube 7 is installed in the lower layer, and the sample water is collected through the sample tube 7 for storage and temporary storage; a diverter 15 is installed under the partition, and a three-way solenoid valve is arranged inside the diverter 15, wherein one end of the diverter 15 is connected to the water pump 3 through a water pipe for the entry of water source, and the other end is connected to the outside through a water pipe, which is mainly used to discharge the sample water remaining in each connected water pipe to improve the accuracy of sampling in each time period, and the last end is connected to a water outlet 12. After the water quality is discharged for a period of time, the water is injected into the sample tube 7 through the water outlet 12 for collection and storage.

[0028] according to Figure 2 and Figure 3 As shown, a base 4 is installed at the bottom of the door panel 1, and a motor is installed inside the base 4. The output end of the motor is connected to a carrier plate 9 located at the bottom of the lower layer inside the box body 2. A plurality of sample tubes 7 are installed on the carrier plate 9, which are distributed in a ring shape. Different sample tubes 7 can be positioned below the water outlet 12 in turn by rotation to collect and store sampled water. Through the motor and the sample tubes 7 distributed in a ring shape, water samples of different time periods can be stored in turn when receiving sampled water, which makes sampling more convenient and can flexibly store a variety of water samples. A handle 16 is installed on the outside of the door panel 1.

[0029] according to Figure 3 and Figure 7 As shown, a column 11 is installed on the carrier 9, and a limiting ring 6 is installed on the column 11. A plurality of clamping rings are installed on the limiting ring 6, and a plurality of sample tubes 7 are clamped by the clamping rings. A plurality of grooves for placing the sample tubes 7 are opened around the column 11, which can be more stable after placement. At the same time, since the length of the sample tube 7 is relatively long, the plurality of sample tubes 7 are limited by the limiting ring 6 for positioning and fixing. At the same time, the limiting ring 6 can slide on the column 11, which is convenient for disassembly and installation.

[0030] according to Figure 3 , Figure 5 and Figure 6As shown, a sealing plate 8 installed on the partition is provided above the sample tube 7, and a plurality of plugs 10 are installed on the sealing plate 8, and a notch is opened on the sealing plate 8. When the sealing plate 8 is installed on the partition, the notch position is used for the water outlet head 12 to pass through, and a spring 14 is provided inside the plug 10, and a clamping plate is connected to the top of the spring 14, and the clamping plate is connected to the sealing plate 8. The plug 10 can move on the sealing plate 8, and when squeezed, the plug 10 will slide, and the bottom end of the plug 10 is arc-shaped, and when the sample tube 7 rotates, pressure can be generated on the plug 10 through the screen, and then the top opening of the sample tube 7 is closed under the action of the spring 14, so as to reduce the contamination of the water sample by external impurities, and with the help of the arc-shaped end at the bottom of the plug 10, the plug 10 can be squeezed during rotation, so that the plug 10 rises, which will not affect the rotation of the sample tube 7, and is more convenient for sampling.

[0031] In summary, in this embodiment, according to the water quality sampling device of this embodiment, by setting up multiple sample cylinders 7, it can rotate under the drive of a motor, and can perform cyclic collection when collecting sampled water. At the same time, multiple sample cylinders 7 can also be set to separate bottles for water samples collected in different time periods, and different types of water samples can be classified and stored.

[0032] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
