[0004] However, the above technology still has the following problems:

[0005] When sending a container filled with water into a water body at different depths for water sampling, the water body has a certain fluidity, which will cause the line to be not in a vertical state, making it difficult to determine the depth of the sampling container in the water. As a result, there will be certain errors in the water sample after water sampling. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 3 A stratified sampling device for water quality testing includes a base 1, a support column 2 is fixedly connected to the base 1, a multi-stage cylinder 3 is fixedly connected to the support column 2, a rotating mechanism is fixedly connected to the multi-stage cylinder 3, a traction rope 5 is placed on the rotating mechanism, the output end of the traction rope 5 is fixedly connected to a counterweight 6, the other end of the traction rope 5 is fixedly connected to the driving mechanism, a pressure gauge 7 is fixedly connected to the counterweight 6, a through hole 8 is opened on the counterweight 6, an interface 9 is fixedly connected to the outside of the through hole 8, a water pump 10 is fixedly connected to the base 1, an inlet pipe 11 and a water outlet pipe 12 are fixedly connected to the water pump 10, and the inlet pipe 11 is fixedly connected to the interface 9.

[0022] The structure of the stratified sampling device for water quality detection in the present invention is similar to that of the existing stratified sampling device for water quality detection in environmental testing. For example, the patent with announcement number CN221464983U discloses a stratified sampling device for water quality detection in environmental testing. The main improvement of the present invention is that the counterweight 6 and the waterproof pressure sensor or pressure transmitter with wireless communication function are sent into the water through the traction rope 5, and the data can be transmitted to the mobile phone or computer. The position of the counterweight 6 in the water is determined by calculation, and it is not affected by the flow of the water body. The water of different depths is pumped up by the water pump 10. Figures 1 to 3 As shown, the stratified sampling device for water quality detection in the utility model drives the motor 18 and the multi-stage cylinder 3 at the same time when in use. During the process of the multi-stage cylinder 3 becoming longer, the counterweight 6 moves toward the far end of the water surface. The motor 18 rotates the winding wheel 19, so that the traction rope 5 becomes longer as the counterweight 6 moves, so that the counterweight 6 is above the water surface. After a period of time, the multi-stage cylinder 3 is turned off, the motor 18 continues to work, and the traction rope 5 continues to lengthen, thereby sending the counterweight 6 into the water. Under the action of the gravity of the counterweight 6, the pressure gauge 7 is suspended in the water body, and the data is transmitted to the mobile phone or computer through the pressure gauge 7. The depth of the pressure gauge 7 in the water body can be calculated, and the length of the traction rope 5 can be adjusted by the motor 18, thereby changing the position of the counterweight 6 and the pressure gauge 7, so as to sample water at different depths. By starting the water pump 10, water flows from the through hole 8 into the water inlet pipe 11 under the action of the water pump 10, and flows out from the water outlet pipe 12. It should be noted that when sampling water at different depths, it is necessary to extract water for a period of time before sampling and saving the water, so as to clean the water inlet pipe 11 and the water outlet pipe 12, so as to avoid cross-contamination of the water sample by the original residual water in the water inlet pipe 11 and the water outlet pipe 12, thereby affecting the accuracy of the detection.

[0023] like Figure 1 As shown, a support rod 13 is fixedly connected to the base 1 , the upper end of the support rod 13 is fixedly connected to the multi-stage cylinder 3 , and a circular hole 14 is opened on the support rod 13 .

[0024] Specifically, the support rod 13 is used to strengthen the support of the multi-stage cylinder 3, and the circular hole 14 is used to allow the traction rope 5 to flow normally.

[0025] like Figure 1 As shown, there are two rotating mechanisms, which are fixedly connected to the output end and the end of the multi-stage cylinder 3 respectively.

[0026] Specifically, the two rotating mechanisms can enable the traction rope 5 to move along the same path.

[0027] like Figure 3 As shown, the rotating mechanism includes two mutually parallel fixed blocks 15 fixedly connected to the multi-stage cylinder 3, and a roller 16 is rotatably connected between the two fixed blocks 15.

[0028] Specifically, the traction rope 5 is placed on the roller 16 . When the traction rope 5 becomes longer, the roller 16 rotates along with it, and can also limit the position of the traction rope 5 .

[0029] like Figure 1 As shown, the driving mechanism includes two fixed plates 17 fixedly connected to the base 1, a motor 18 is fixedly connected to the outer side of the fixed plate 17, a winding wheel 19 is rotatably connected between the two fixed plates 17, and the output end of the motor 18 is fixedly connected to the winding wheel 19.

[0030] Specifically, before sampling, the motor 18 is driven and the reel 19 is rotated to rotate the traction rope 5 from the reel 19. Under the action of the counterweight 6, the traction rope 5 is in a straightened state and moves along the same path, thereby sending the counterweight 6 into the water body and adjusting the depth of the counterweight 6 in the water body. After the sampling is completed, the counterweight 6 can be pulled out of the water body by following the opposite operation.

[0031] like Figure 2 As shown, the outer side of the through hole 8 is fixedly connected with a filter screen 4 .

[0032] Specifically, the filter screen 4 can prevent large particles in the water from entering the through hole 8 and the water inlet pipe 11, thereby avoiding blockage.

[0033] like Figure 1 As shown, the pressure gauge 7 is a waterproof pressure sensor or pressure transmitter with wireless communication function.

[0034] Specifically, by transmitting data to a mobile phone or a computer via the pressure gauge 7 , the depth of the counterweight 6 and the pressure gauge 7 in the water body can be calculated, thereby facilitating sampling of water at different depths.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
