Description

Technical Field

[0001] The utility model relates to the technical field of river water sampling, in particular to a river water sampling mechanism for water conservancy projects. Background Technique

[0002] River water sampling is an important detection in water conservancy projects. By extracting river water samples, the water quality of the river is detected. Before the detection, a river water sampling mechanism is used to sample the river water. However, the existing river water sampling mechanisms still have some drawbacks. For example, when sampling, when the water level is low, a simple river water sampling mechanism cannot effectively and quickly sample, which will lead to difficult sampling. Although a complex-structured river water sampling mechanism can sample, it is not easy to carry. Therefore, there is a lack of a river water sampling mechanism in the technology that is simple in structure, easy to carry, and can meet different usage situations. For this reason, we propose a river water sampling mechanism for water conservancy projects. Content of the Utility Model

[0017] Embodiment 1:

[0018] Please refer toFigure 1-2 , the present utility model provides a technical solution: a river water sampling mechanism for water conservancy projects, which refers to a device for river water sampling, including a base 1. When sampling river water, the base 1 can be placed on the shore. A vertical rod 2 is provided at the top of the base 1. An installation plate 3 is provided at the left top of the vertical rod 2. Fixed rods 4 are provided on the front and rear end faces on the left side of the installation plate 3. A guide wheel 5 is provided on the left side of the opposite faces of the fixed rods 4. A micro water pump 6 is provided on the right side at the top of the installation plate 3. A battery pack is installed at the bottom of the installation plate 3, and the battery pack can provide power support for the operation of the micro water pump 6. A water suction pipe 7 is provided on the left side of the micro water pump 6, and the end of the water suction pipe 7 away from the micro water pump 6 is arranged at a right angle of 90 degrees downward after passing through the guide wheel 5. This setting enables convenient extraction of river water even when the river water level is low. A water pipe adapter 8 is provided at the end of the water suction pipe 7 away from the micro water pump 6. A matching water pipe connector 9 is provided at the bottom of the water pipe adapter 8. A sampling pipe 10 is provided at the bottom of the water pipe connector 9. Different lengths of sampling pipes 10 can be replaced according to requirements through the cooperation of the water pipe adapter 8 and the water pipe connector 9, so as to meet different usage requirements. A filter head 11 is provided at the bottom of the sampling pipe 10. When sampling river water, the end of the sampling pipe 10 with the filter head 11 can be thrown into the river. The provided filter head 11 can play a filtering role to avoid sucking debris together when extracting river water, thus causing a blockage phenomenon. An outlet pipe 12 is provided on the right side of the micro water pump 6. The micro water pump 6 can extract river water through the cooperation of the water suction pipe 7 and the sampling pipe 10, and the extracted river water will flow into the outlet pipe 12. A sampling bottle fixing bracket 13 is provided at the right top of the vertical rod 2. A sampling bottle 14 is placed in the sampling bottle fixing bracket 13. An inlet 15 matching the outlet pipe 12 is provided at the top of the sampling bottle 14. The river water in the outlet pipe 12 will be discharged into the sampling bottle 14 through the inlet 15, and thus the sampling process of the river water can be completed.

[0019] Among them, preferably, a filter net 18 is movably connected inside the filter head 11. The provided filter net 18 can prevent sucking debris during pumping, thus causing damage to the micro water pump 6. An external thread 19 is provided on the outer circumference of the filter net 18, and an internal thread 20 matching the external thread 19 is provided on the inner wall of the inner cavity of the filter head 11. Through the cooperation of the external thread 19 and the internal thread 20, the filter net 18 can be disassembled from the inner cavity of the filter head 11, so as to replace or clean the filter net 18, thereby avoiding the blockage phenomenon.

[0020] Preferably, a rotating paddle 21 is provided at the center of the bottom of the filter net 18. The provided rotating paddle 21 can facilitate the staff to quickly rotate the filter net 18, so as to remove the filter net 18. Grooves 22 are provided on both the left and right sides of the inner wall of the filter head 11, and counterweight blocks 23 are provided in the grooves 22. The provided counterweight blocks 23 can enable the filter head 11 to quickly sink into the water, preventing it from floating on the water surface, so as to absorb a large amount of floating objects when pumping water.

[0021] Preferably, connecting rods 16 are vertically provided at the centers of the front and rear end faces of the top of the mounting plate 3, and handles 17 are horizontally provided at the tops of the connecting rods 16. Through the handles 17, it is convenient for the staff to lift the entire device, thus facilitating carrying.
