[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] This utility model provides a groundwater level and water quality sampler, including a support frame 101 and a sampling mechanism. The sampling mechanism includes a winding roller 102, a steel ruler belt 103, a reference rod 104, an installation assembly, a Bayer tube 105, a first one-way valve 106, a second one-way valve 107, a water level sensor 108, a disc 109, and a gripping rod 110. The installation assembly includes a fixed plate 111, a moving plate 112, an extension plate, two limiting rings 113, and a displacement unit. The displacement unit includes a screw 114 and a force-applying block 115. The extension plate includes a positioning plate 116 and a sliding plate 117. The aforementioned solution solves the technical problems of existing water quality samplers in actual use, such as insufficient sample volume, easy leakage from the ball valve of the Bayer tube 105, and difficulty in distinguishing samples from different water levels.
[0020] In this specific embodiment, the support frame 101 is placed on the ground for support, and the support frame 101 supports the entire device to improve stability.
[0021] The winding roller 102 is mounted on the support frame 101. One end of the steel ruler strip 103 is wound around the winding roller 102, and the other end of the steel ruler strip 103 is fixedly connected to the mounting assembly. The Bayler tube 105 is mounted on the mounting assembly and has an inlet 118 and an outlet 119. The first one-way valve 106 and the second one-way valve 107 are respectively mounted on the inlet 118 and the outlet 119. The water level sensor 108 is mounted on the inlet 118. The reference rod 104 is mounted on the support frame 101. The steel ruler strip 103 has graduation lines. In actual use, the Bayler tube 105 is first placed on the mounting assembly, and then the winding roller 102 is rotated to release the steel ruler strip 103 until the water level sensor 108 contacts the water surface. An alarm is triggered. At this time, the scale line on the steel ruler strip 103 is read and recorded based on the reference rod 104. Then, the steel ruler strip 103 is released and the scale line on the steel ruler strip 103 is observed. After obtaining the specified depth (the specified depth is equal to the scale corresponding to the reference rod 104 minus the recorded scale), the water inlet 118 is placed at the specified water level. The first one-way valve 106 and the second one-way valve 107 are opened. At this time, due to the difference between the air pressure and water pressure in the Bayer tube 105, the water in the water level can enter the Bayer tube 105 through the water inlet 118. Then, the steel ruler strip 103 is wound up, and the Bayer tube 105 is lifted and taken out. This method solves the technical problems of existing water quality samplers in actual use, such as small sample volume, easy leakage of the ball valve of the Bayer tube 105, and difficulty in distinguishing samples of different water content levels.
[0022] Secondly, the fixing plate 111 is fixedly connected to the steel ruler strip 103. The two ends of the extension plate are respectively connected to the fixing plate 111 and the moving plate 112. The two limiting rings 113 are fixedly connected to the Belle tube 105. The fixing plate 111 and the moving plate 112 both have through holes 120. The Belle tube 105 is placed in the two through holes 120, and the two limiting rings 113 are in contact with the fixing plate 111 and the moving plate 112. The displacement unit is used to drive the moving plate 112 to move. When the Belle tube 105 needs to be installed, the moving plate 112 is first moved by the displacement unit. Then the Belle tube 105 is placed between the fixing plate 111 and the moving plate 112. Then the moving plate 112 is moved closer to the fixing plate 111 by the displacement unit, so that the moving plate 112 and the fixing plate 111 abut against the two limiting rings 113 to complete the installation. Conversely, it is easy to disassemble.
[0023] Meanwhile, the displacement unit includes a screw 114 and a force-applying block 115. One end of the screw 114 is fixedly connected to the force-applying block 115, and the other end of the screw 114 passes through the fixed plate 111 and is rotatably connected to the moving plate 112. The screw 114 is threadedly engaged with the fixed plate 111. In actual use, the force-applying block 115 drives the screw 114 to rotate. When the screw 114 rotates, it rotates on the fixed plate 111, thereby generating relative displacement on the fixed plate 111. When the screw 114 moves, it drives the moving plate 112 to move.
[0024] In addition, the positioning plate 116 is fixedly connected to the fixed plate 111, one end of the sliding plate 117 is slidably connected to the positioning plate 116, and the other end of the sliding plate 117 is fixedly connected to the moving plate 112. When the moving plate 112 moves, it drives the sliding plate 117 to slide on the positioning plate 116 to improve the stability of the moving plate 112.
[0025] Furthermore, the disc 109 is fixedly connected to the take-up roller 102, and the gripping rod 110 is eccentrically disposed on the disc 109. By gripping the gripping rod 110 and applying force to rotate the gripping rod 110, the disc 109 can be driven to rotate, and the disc 109 can drive the take-up roller 102 to rotate.
[0026] In the specific use of the groundwater level and quality sampler of this utility model, the Beller tube 105 is first placed on the mounting assembly. Then, the take-up roller 102 is rotated to release the steel tape 103 until the water level sensor 108 contacts the water surface and triggers an alarm. At this point, the scale line on the steel tape 103 is read and recorded based on the reference rod 104. Subsequently, the steel tape 103 is released again, and the scale line on the steel tape 103 is observed. After obtaining the specified depth (the specified depth is equal to the scale corresponding to the reference rod 104 minus the recorded scale line), the sampler is used to determine the depth. By adjusting the water level (degree), the inlet 118 can be positioned at a specified water level. The first one-way valve 106 and the second one-way valve 107 are opened. At this time, due to the pressure difference between the air pressure and the water pressure inside the Bayer tube 105, the water in the water level can enter the Bayer tube 105 through the inlet 118. Then, the steel ruler 103 is wound up, and the Bayer tube 105 is lifted and removed. This method solves the technical problems of existing water quality samplers in actual use, such as small sample volume, easy leakage from the ball valve of the Bayer tube 105, and difficulty in distinguishing samples from different water content levels.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
