Description

Technical Field

[0001] The utility model relates to the technical field of water quality investigation, in particular to a portable groundwater sampling device. Background Technique

[0002] Groundwater is an important part of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial and mining, and cities. The storage of groundwater is like forming a huge reservoir underground. With its stable water supply conditions and good water quality, it has become an important water source for agricultural irrigation, industrial and mining enterprises, and urban domestic water, and an important water resource essential for human society. However, under certain conditions, the change of groundwater will also cause adverse natural phenomena such as waterlogging, salinization, landslides, and ground settlement. Therefore, the sampling and detection of groundwater are particularly important.

[0003] A portable groundwater collection device with the authorization announcement number of CN 212180349 U in China can close and open the channel for the water sample in the sample accommodation cavity to drain out of the sample accommodation cavity by adjusting the positions of the first sample outlet hole and the second sample outlet hole without disassembling the suction device, making the transfer of the water sample very convenient.

[0004] However, there are still some deficiencies in the use of this patent. For water quality investigation and prediction, multiple samples are required to accurately predict. Therefore, multiple samples are needed to detect a set of data. Most of the existing collection devices only have one collection unit and can only collect one sample at a time. Moreover, the traditional collection unit is easily contaminated by soil or other microorganisms when pulled upward. Therefore, the efficiency of collecting data is very low, and it wastes manpower and material resources, and the practicability is very low. In addition, most of the existing collection devices use the method of manual wire winding for wire winding, which is very inconvenient to use, and the device is easy to move, which easily leads to unstable water quality and reduces the accuracy of the collected data.

The material of the bottle stopper 310 is rubber, and the cross-section of the bottle stopper 310 is equal to the cross-section of the bottle mouth of the collection bottle 304.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown in the figure, the positioning component 1 includes a support base 101. An infrared sensor 103 is fixedly connected to the bottom of the support base 101. A wire groove 102 is arranged on the top of the support base 101. A positioning groove 105 is formed in the top of the support base 101. A tapered column 104 is threadedly connected in the positioning groove 105. The wire winding component 2 includes a first fixing plate 201 and a second fixing plate 205 fixedly connected to the top of the positioning component 1. A motor 207 is fixedly installed on the side of the second fixing plate 205 through a fixing rod 206. The output end of the motor 207 is fixedly connected to a wire winding roller 202. A limiting groove 203 is formed on the outer part of the wire winding roller 202. The limiting groove 203 is rotationally connected to the first fixing plate 201. A nylon rope 204 is wound around the outer part of the wire winding roller 202.

[0028] Among them, by setting the positioning component 1, the stability of the device is realized, preventing the water quality from being unstable due to shaking during the process of winding and unwinding the wire. First, place the collection component 3 in the shaft, and then fix the support base 101 on the ground through the tapered column 104. Pass the tapered column 104 into the ground, and then control the motor 207 to work and the wire winding roller 202 to rotate through the control box 4, and control the descending speed of the collection component 3 by controlling the rotation speed of the motor 207, so as to make the collection component 3 descend smoothly as much as possible, thereby improving the accuracy of the collected data.

[0029] In this embodiment, as Figure 1 、 Figure 4 and Figure 5 shown, the collection component 3 includes a third fixing plate 301 fixedly connected to the bottom of the nylon rope 204. A connecting rod 302 is fixedly connected to the bottom of the third fixing plate 301. A fourth fixing plate 303 is fixedly connected to the bottom of the connecting rod 302.

The collection component 3 is moved downward through the nylon rope 204. Under the action of the counterweight 309, the shaking amplitude of the collection component 3 can be reduced. When the probe 307 touches the water surface, a signal is sent to the control box 4, and the control box 4 controls the infrared sensor 103 to measure the distance. The distance between the third fixing plate 301 and the infrared sensor 103 at this time is measured and displayed through the display screen 5. Then, the water level height of the groundwater can be obtained through calculation. At the same time, the electric telescopic rod 306 is controlled to extend by pressing the button 6. Then, under the action of the counterweight 309, the collection component 3 continues to move downward until the water surface submerges the collection bottle 304, and the water sample enters the interior of the collection bottle 304. After standing for a period of time, the electric telescopic rod 306 is controlled to move the cross-shaped plate 305 to cover the collection bottle 304 with the bottle stopper 310, and the rope is retracted to pull the collection component 3 upward.
