[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] Example 1:
[0036] Reference Figure 1-3 A groundwater detection device 100 includes: a detection cup 101, a first connecting block 102, a second connecting block 103, a mounting block 104, a first sealing ring 105, and a second sealing ring 106. The first connecting block 102 is located on the circumference of the detection cup 101 and is threadedly connected to it. The second connecting block 103 is located at the upper end of the detection cup 101 and is threadedly connected to it. The mounting block 104 is located at the upper end of the detection cup 101 and engages with it.
[0037] A first sealing ring 105 is fitted onto a first connecting block 102. A second sealing ring 106 is fitted onto a second connecting block 103. The mounting block 104 includes a receiving hole 104a and a slot 104b. A portion of the detection cup 101 is located within the slot 104b. The first connecting block 102 includes a water inlet hole 102a, which communicates with the detection cup 101. The second connecting block 103 includes a 103a and a water outlet hole 103a, which communicates with the detection cup 101. The lower end of the second connecting block 103 extends into the detection cup 101. Multiple mounting blocks 104 are provided, equidistantly distributed along the circumference of the detection cup 101. A water inlet pipe is connected to the first connecting block 102. Water is pumped into the detection cup 101 via a water pump (submersible pump or air pump), and then discharged from the detection cup 101 through the second connecting block 103, thus enabling real-time monitoring of the well water. It is equipped with multiple mounting blocks 104, and the receiving holes 104a of the mounting blocks 104 allow the instrument probe to be inserted for detection. The detection cup 101 is made of transparent acrylic, which can be used to observe the color change of the water.
[0038] This effectively avoids data deviations caused by manual water sample collection being exposed to air or secondary transfer, especially for dissolved oxygen (DO) levels, which are easily distorted by aeration, affecting the authenticity and representativeness of groundwater samples. It makes the tested water samples more representative. It enables real-time monitoring of water data while reducing water sample contact with air, effectively addressing the deviations in dissolved oxygen detection caused by aeration, resulting in more accurate data and more representative groundwater samples.
[0039] Example 2:
[0040] Reference Figure 4-8The difference from Embodiment 1 is that, to prevent the detection cup 101 from tipping over, a fixing component is added. This fixing component, used to secure the detection cup 101, includes: a fixing block 107, a limiting block 108, a limiting post 109, a connecting plate 110, a first spring 112, and a push plate 113. The fixing block 107 is located on one side of the detection cup 101. The fixing block 107 is fixedly connected to a wastewater tank 114 on one side. The wastewater tank 114 is used to contain discharged wastewater. The limiting block 108 is fixedly connected to the detection cup 101.
[0041] The limiting post 109 is vertically slidably connected to the fixing block 107. Specifically, the fixing block 107 includes a guide hole 107a, and part of the limiting post 109 is located within the guide hole 107a and moves axially along the guide hole 107a. The connecting plate 110 is fixedly connected to the limiting post 109. The first spring 112 is sleeved on the limiting post 109, and its two ends are fixedly connected to the fixing block 107 and the connecting plate 110, respectively. The fixing block 107 includes a limiting groove 107b, which is used to limit the positioning of the limiting block 108. The limiting block 108 includes a limiting hole 108a, and the limiting post 109 is inserted into the limiting hole 108a to limit the positioning of the limiting block 108.
[0042] The fixing block 107 includes a first cavity 107c, which is used to accommodate the first spring 112. The push plate 113 is located at the upper end of the limiting block 108 and is fixedly connected to the limiting block 108. Pulling the push plate 113 causes the limiting block 108 to move, which in turn causes the limiting post 109 to move. Then, the limiting block 108 is inserted into the limiting groove 107b of the fixing block 107. Then, the push plate 113 is released, and the limiting block 108 will reset under the action of the first spring 112. The movement of the limiting block 108 causes the limiting post 109 to be inserted into the limiting hole 108a, thereby fixing the limiting block 108 and thus fixing the detection cup 101 to prevent it from being accidentally knocked over.
[0043] Workflow: When it is necessary to fix the test cup 101, pull the push plate 113. The movement of the push plate 113 causes the limit block 108 to move, and the movement of the limit block 108 causes the limit post 109 to move. Then, the limit block 108 is inserted into the limit groove 107b of the fixing block 107. Then, release the push plate 113. Under the action of the first spring 112, the limit block 108 will be reset. The movement of the limit block 108 causes the limit post 109 to be inserted into the limit hole 108a, thereby fixing the limit block 108 and completing the fixation of the test cup 101. This prevents the test cup 101 from being accidentally knocked over, and the fixation of the test cup 101 is very convenient.
