DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a foldable water sampling device, including a top cover 1, the top cover 1 is rotatably connected to one side of a bottom box 2, a compartment cavity 3 is provided inside the bottom box 2, a sampling pump 4 is provided inside the compartment cavity 3, a connecting pipe 5 is plugged into the bottom end of the sampling pump 4, a sampling tube 6 is plugged into the bottom end of the connecting pipe 5, a telescopic bottle rack 7 is threadedly connected to the inner wall of one side of the bottom box 2, a sampling bottle 8 is clamped inside the telescopic bottle rack 7, and handles 9 are provided on the left and right sides of the top cover 1.

[0022] In this embodiment, Figure 4 and Figure 5 As shown, the connecting pipe 5 is composed of a connecting main pipe 501 and a connecting branch pipe 502, wherein the top end of the connecting main pipe 501 is plugged into the sampling pump 4, the top end of the connecting branch pipe 502 is plugged into the connecting main pipe 501, and the bottom end of the connecting branch pipe 502 is plugged into the top end of the sampling tube 6; it should be noted that in the specific operation process, the sampling personnel can first open the top cover 1, and then insert the sampling tube 6 into the water sample to be tested. At the same time, start the sampling pump 4 to generate suction force, and through the connecting main pipe 501 plugged therein, the water sample around the sampling tube 6 plugged with each connecting branch pipe 502 is extracted into the interior of the sampling tube 6 to complete the sampling. The setting of the sampling pump 4 and the connecting pipe 5 in the utility model can complete the water sampling operation of multiple sampling tubes 6 at one time.

[0023] In this embodiment, Figure 1 and Figure 2 As shown, the sampling tube 6 is a retractable tube body, and the total lengths of different tube bodies are inconsistent. It should be noted that when an ordinary sampling tube 6 is used to sample water samples, it is often because the length of the tube body is fixed and unchanged, so only water samples of a single depth can be sampled. In the present utility model, the sampling tube 6 is designed as a retractable tube body, and the total length of each tube body is inconsistent. In the specific operation, the sampling personnel can manually stretch each sampling tube 6 to extend it to the maximum length, and then insert these sampling tubes 6 into the water sample to be tested. At this time, the sampling tubes 6 of different lengths will be inserted into the water area of ​​different depths, and with the cooperation of the sampling pump 4 and the connecting pipe 5, the sampling operation of water samples of different depths is completed. After completing the sampling operation, the sampling personnel can compress each sampling tube 6 back to its original length, and then close the top cover 1 and the bottom box 2, and the entire sampling device can be folded into a closed box body, which is convenient for the sampling personnel to carry with them.

[0024] In this embodiment, Figure 3 and Figure 4 As shown, a sampling valve 601 is installed on the outer wall of the tube body of the sampling tube 6; it should be noted that after completing the sampling operation of water samples of different depths through the sampling pump 4, the sampling personnel can start the electric telescopic rod 701 at this time, and push the sampling bottle 8 to the bottom of the sampling tube 6, so that the bottle mouth of the sampling bottle 8 corresponds to the tube mouth of the sampling tube 6. At the same time, the sampling personnel can open the sampling valve 601 installed on the outer wall of each sampling tube 6, so that the water sample originally stored in the sampling tube 6 can smoothly flow into the corresponding sampling bottle 8, and then cover the bottle mouth of the sampling bottle 8 with a bottle cap to complete the sample collection. In this process, by adjusting the opening and closing degree of the sampling valve 601, the flow rate and flow velocity of the water sample flowing out of the sampling tube 6 can be controlled, thereby ensuring the accuracy and stability of the sampling process.

[0025] In this embodiment, Figure 4As shown, the telescopic bottle rack 7 is composed of an electric telescopic rod 701, a telescopic U-shaped frame 702 and an insert plate 703, wherein the electric telescopic rod 701 is screwed to the inner wall of the rear side of the bottom box 2, the telescopic U-shaped frame 702 is plugged into the driving end of the electric telescopic rod 701, and the insert plate 703 is arranged on the inner wall of the telescopic U-shaped frame 702; it should be noted that after the sampling personnel completes the water sampling of waters of different depths, the sampling personnel can start the electric telescopic rod 701 through an external controller, so that the driving end of the electric telescopic rod 701 begins to extend horizontally and pushes the telescopic U-shaped frame 702 and the insert plate 703 plugged therein toward the sampling tube together. 6 until the mouth of the sampling bottle 8 connected to the inside of the plug plate 703 corresponds to the mouth of the sampling tube 6, and then the sampling device can stop. At the same time, the sampling personnel can open the sampling valve 601 installed on the outer wall of the sampling tube 6 to allow the water stored in the sampling tube 6 to flow into the interior of the sampling bottle 8 to complete the collection of the water sample. After that, the sampling personnel can seal the mouth of the sampling bottle 8 and restart the electric telescopic rod 701 to retract the sampling bottle 8 to its original position. At the same time, the top cover 1 is covered on the top of the bottom box 2, so that the entire sampling device is folded into a closed box body for easy carrying.

[0026] In this embodiment, Figure 3 and Figure 2 As shown, the inner walls on the left and right sides of the bottom box 2 are provided with suspended balls 201; it should be noted that when using the sampling device in the utility model to sample water, the sampling personnel can first open the top cover 1 covering the bottom of the bottom box 2, and stretch the tube body of the sampling tube 6 to the maximum length. At the same time, the sampling personnel can hold the handle 9 and vertically insert the sampling tube 6 into the water sample to be tested. At the same time, the suspended balls 201 arranged on the left and right sides of the bottom box 2 can provide buoyancy for the entire sampling device, so that it can float on the water surface of the water sample to be tested, thereby reducing the burden on the sampling personnel, and can also ensure the stability of the entire sampling device when sampling through the sampling tube 6, thereby ensuring the accuracy of the final sampling result.

[0027] The use method and advantages of the utility model: When the foldable water sampling device is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the sampling personnel can open the top cover 1 covering the bottom of the bottom box 2, and stretch the tube body of the sampling tube 6 to the maximum length. At the same time, the sampling personnel can hold the handle 9 and vertically insert the sampling tube 6 into the water sample area at different depths. At the same time, the suspension balls 201 arranged on the left and right sides of the bottom box 2 can provide buoyancy for the entire sampling device to ensure the stability of the entire sampling device. At this time, the sampling pump 4 can be started, and the water sample around the sampling tube 6 connected to each connecting branch pipe 502 can be drawn into the interior of the sampling tube 6 through the connecting main pipe 501 connected thereto to complete the sampling, and the sampling valve 601 is closed to store the water sample in the interior of the sampling tube 6, and then the sampling is completed. The personnel can start the electric telescopic rod 701 through the external controller to push the telescopic U-shaped frame 702 and the plug plate 703 to move together in the direction of the sampling tube 6 until the bottle mouth of the sampling bottle 8 connected to the inside of the plug plate 703 corresponds to the tube mouth of the sampling tube 6, and then stop. At the same time, the sampling valve 601 is opened again to allow the water stored in the sampling tube 6 to flow into the interior of the sampling bottle 8 to complete the collection of the water sample. After that, the sampling personnel can seal the bottle mouth of the sampling bottle 8, and restart the electric telescopic rod 701 to retract the sampling bottle 8 to its original position, and at the same time cover the top cover 1 on the top of the bottom box 2, so that the entire sampling device is folded into a closed box body, which is convenient for carrying.
