[0022] 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 technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4The urban water environment monitoring sampling device shown in the figure comprises a mobile vehicle body 1, a U-shaped base 2 is installed on the top outer wall of the mobile vehicle body 1, a supporting horizontal axis 3 is rotatably connected to the U-shaped base 2, an adjusting cylinder 4 is installed on the side wall of the supporting horizontal axis 3, a water pumping pipe 6 is wound on the side wall of the adjusting cylinder 4, and limiting plates are respectively installed on both ends of the adjusting cylinder 4 to limit the water pumping pipe 6 wound thereon, a water delivery pump 5 is installed on the top outer wall of the mobile vehicle body 1, the input end of the water delivery pump 5 is connected to one end of the water pumping pipe 6, and the output end of the water delivery pump 5 is connected to a water outlet pipe 13, A supporting vertical rod 7 is rotatably connected to the mobile vehicle body 1, and a supporting bottom plate 8 is installed at one end of the supporting vertical rod 7. U-shaped limit blocks 9 and storage tanks 10 are respectively installed on the top outer wall of the supporting bottom plate 8. The number of U-shaped limit blocks 9 and storage tanks 10 is four, and they are evenly distributed on the top of the supporting bottom plate 8. The U-shaped limit block 9 is installed with a clamping assembly 11 for fixing the storage tank 10. When sampling, first place one end of the water pump 6 in water, and then work the water delivery pump 5 so that the water delivery pump 5 can deliver the water sample to one of the storage tanks 10 through the outlet pipe 13, and then the mobile vehicle body 1 is moved to the storage tank 10. A driving motor 14 is installed on the top outer wall of the moving vehicle body 1, and a driving bevel gear 15 is connected to the output end of the driving motor 14. A driven bevel gear 16 is installed on the side wall of the supporting vertical rod 7. The driving bevel gear 15 is meshed and connected with the driven bevel gear 16. A rotating motor 18 is installed on the top outer wall of the moving vehicle body 1, and a driving pulley 19 is connected to the output end of the rotating motor 18. A driven pulley 17 is installed on one end of the supporting horizontal shaft 3. The driven pulley 17 is connected to the driving pulley 19 through a transmission belt. After the water sample at one position is collected, the driving pulley is driven by the rotating motor 18. The wheel 19 rotates so that the supporting horizontal axis 3 can drive the adjusting cylinder 4 to rotate, thereby winding the water pumping pipe 6 around the adjusting cylinder 4, and then adjusting the position of the water inlet end of the water pumping pipe 6. Then, the driving motor 14 drives the active bevel gear 15 at its output end to rotate, so that the supporting vertical rod 7 drives the supporting bottom plate 8 to rotate a certain angle, thereby rotating another storage tank 10 to below the water outlet of the water outlet pipe 13, and then the water delivery pump 5 continues to work to pump water into the storage tank 10. Therefore, the device can collect water samples from different positions at one time, which is convenient for subsequent comprehensive evaluation of the water quality.

[0024] In this embodiment, the end of the water suction pipe 6 away from the water delivery pump 5 is connected to a filter cartridge 20, and a counterweight block 21 is installed on the bottom outer wall of the filter cartridge 20. When water enters one end of the water suction pipe 6, large particles of impurities such as aquatic plants in the water can be filtered out through the filter cartridge 20 to prevent the impurities from damaging the water pump, and the counterweight block 21 can help to sink one end of the water suction pipe 6 into the water.

[0025] In this embodiment, a support vertical plate 12 is installed on the top outer wall of the mobile vehicle body 1 , and the support vertical plate 12 is connected to the water outlet pipe 13 , so that the water outlet pipe 13 can be supported by the support vertical plate 12 .

Guide rods 1102 are slidably engaged on the guide base plate 1101, and clamping plates 1103 and guide plates 1105 are respectively installed at both ends of the guide rod 1102. A guide shaft 1104 is installed on one side wall of the guide base plate 1101. The guide shaft 1104 is slidably engaged with the guide plate 1105, and a clamping spring 1106 is arranged on the side wall of the guide shaft 1104. After sampling is completed, the storage tank 10 containing the water sample is removed, and then the new storage tank 10 is placed on the top of the supporting base plate 8 and inside the U-shaped limit block 9. The guide plate 1105 is driven to move by the clamping spring 1106, so that the clamping plate 1103 can be pressed against one side of the storage tank 10 to fix it, thereby facilitating the replacement of the storage tank 10.

[0027] Working principle of the utility model: The utility model is a sampling device for monitoring urban water environment. When sampling, the filter cartridge 20 at one end of the water pump 6 is first placed in the water, and then the water delivery pump 5 is operated so that the water delivery pump 5 can deliver the water sample to the inside of one of the storage tanks 10 through the water outlet pipe 13;

[0028] By rotating the motor 18 to drive the active pulley 19 to rotate, the support horizontal axis 3 can drive the adjustment cylinder 4 to rotate, so that the water suction pipe 6 can be wound around the adjustment cylinder 4, and then the position of the filter cartridge 20 is adjusted. At the same time, the driving motor 14 drives the active bevel gear 15 at its output end to rotate, so that the support vertical rod 7 can drive the support bottom plate 8 to rotate, thereby rotating another storage tank 10 to below the water outlet of the water outlet pipe 13, and then the water can continue to be pumped into the storage tank 10 through the water delivery pump 5. The device can collect water samples from different positions at one time, which is conducive to the subsequent comprehensive evaluation of the water quality.
