The piston portion is connected to a crank-type pressure rod rotatably mounted on the top of the cylindrical body. A water storage device is provided through the top side wall of the cylindrical body. The water storage device includes a connecting pipe and a water tank. The connecting pipe connects the cylindrical body and the water tank. The water tank connects to a temperature detection device, a pH detection device, a conductivity detection device, a dissolved oxygen detection device, and an ORP detection device. The temperature detection device, the pH detection device, the conductivity detection device, the dissolved oxygen detection device, and the ORP detection device are electrically connected to a control unit.

[0005] Furthermore, the temperature detection device, pH detection device, conductivity detection device, dissolved oxygen detection device, and ORP detection device all include detection bottles.

[0006] Furthermore, an upper fixing ring plate is fixedly installed on the top side wall of the cylinder, and the water storage tank is fixedly installed at the bottom of the upper fixing ring plate. A connecting pipe communicating with the water storage tank is passed through the top of the upper fixing ring plate. The water storage tank and the test bottle are connected by a diversion pipe.

[0019] like Figure 1-4 As shown, a rapid groundwater sampling device includes a cylindrical body 2. A piston 3 is slidably disposed inside the cylindrical body 2. The piston 3 is connected to a crank lever 1 rotatably disposed at the top of the cylindrical body 2. A water storage device 4 is disposed through the top side wall of the cylindrical body 2. The water storage device 4 includes a connecting pipe 401 and a water storage tank 404. The connecting pipe 401 connects the cylindrical body 2 and the water storage tank 404. The water storage tank 404 is connected to a temperature detection device 5, a pH detection device 6, a conductivity detection device 7, a dissolved oxygen detection device 8, and an ORP detection device 9. The temperature detection device 5, pH detection device 6, conductivity detection device 7, dissolved oxygen detection device 8, and ORP detection device 9 are electrically connected to a control unit 10. By pressing the crank lever 1, the groundwater is driven upward by the piston and then enters the water storage device 4 through the connecting pipe 401. Finally, the water flows into each test bottle 1103 through the water storage device 4. The detection device in each test bottle 1103 detects and analyzes the groundwater and feeds the results back to the control unit 10. The control unit 10 displays the data on the display screen.

[0020] like Figure 1 , 3As shown, the temperature detection device 5, pH detection device 6, conductivity detection device 7, dissolved oxygen detection device 8, and ORP detection device 9 all include detection bottles 1103. Temperature detection device 5 also includes an instrument thermometer, pH detection device 6 includes a pH electrode, conductivity detection device 7 includes an electrode, dissolved oxygen detection device 8 includes a dissolved oxygen meter, and ORP detection device 9 includes a conductivity sensor. A lower fixing ring plate 203 is fixedly installed on the side wall near the bottom of the cylinder 2. Five detection bottles 1103 are evenly arranged on the top of the lower fixing ring plate 203. An instrument thermometer, pH electrode, electrode, dissolved oxygen meter, and conductivity sensor are detachably and perforated through the tops of the five detection bottles 1103, respectively. The instrument thermometer, pH electrode, electrode, dissolved oxygen meter, and conductivity sensor are electrically connected to the control unit 10. The instrument thermometer, pH electrode, electrode, dissolved oxygen meter, and conductivity sensor are existing technologies. ① When using an instrumental thermometer for measurement, the thermometer needs to be inserted into the water or the probe of the thermometer needs to be inserted to the required depth. After 2-3 minutes, once the temperature has reached equilibrium, observe and record the water temperature. ② A pH electrode uses the electrode method, based on electrochemical principles, to directly measure the pH value of a water sample. ③ An electrode method is the most commonly used method for conductivity detection. It uses two electrodes (usually platinum or stainless steel electrodes) inserted into the water to be tested; one electrode acts as the current source, transmitting current into the water, while the other electrode receives the current. By measuring the resistance change between the electrodes, the conductivity of the water can be calculated. ④ A dissolved oxygen meter is a device for measuring dissolved oxygen in water. Its working principle is that oxygen permeates through a membrane and is reduced by the working electrode, generating a diffusion current proportional to the oxygen concentration. By measuring this current, the concentration of dissolved oxygen in the water is obtained. ⑤ A conductivity sensor uses the resistance change between electrodes to calculate the ORP value. It has high sensitivity but is easily interfered with by other ions in the water.

[0021] like Figure 3As shown, an upper fixing ring plate 202 is fixedly installed on the top side wall of the cylinder 2. A water storage tank 404 is fixedly installed at the bottom of the upper fixing ring plate 202. A connecting pipe 401 connecting the upper fixing ring plate 202 to the water storage tank 404 is installed through the top of the upper fixing ring plate 202. A switchable water outlet is provided at the bottom of the water storage tank 404. The water storage tank 404 and the test bottle 1103 are connected by a diversion pipe 1101. A level gauge 1104 is provided on the inner wall of the test bottle 1103. An electric valve 1102 is provided on the diversion pipe 1101. The level gauge 1104 is electrically connected to the electric valve 1102. When the level gauge 1104 detects that the liquid level in the test bottle 1103 has reached a predetermined value, it controls the electric valve 1102 to close. A water outlet pipe 1106 is provided at the bottom of the test bottle 1103. A second valve 1105 is provided on the water outlet pipe 1106. A first valve 403 is provided on the connecting pipe 401. The connecting pipe 401, water storage tank 404, diversion pipe 1101 and test bottle 1103 are covered with a heat insulation layer 402 to prevent groundwater from exchanging heat with the outside air, thereby ensuring the accuracy of the test.

[0022] like Figure 3As shown, the piston part 3 includes a connecting rod 301, a piston outer body 302, and a check valve. The connecting rod 301 is rotatably mounted on the top of the piston outer body 302. A sealing layer 304 is fitted on the bottom outer wall of the piston outer body 302. The sealing layer 304 is slidably connected to the inner wall of the cylinder 2 and fits tightly to prevent the collected water from flowing down through the gaps, while ensuring the airtightness of the interior. The piston outer body 302 has a cavity inside and a perforation 305 at the bottom connecting the cavity to the outside. The check valve includes an upper disc 306 and a lower disc 308. A connecting rod 307 is fixedly installed between 06 and the lower circular plate 308. The connecting rod 307 is slidably installed inside the perforation 305. The diameter of the connecting rod 307 is much smaller than the inner diameter of the perforation 305 to ensure that groundwater can enter the upper layer through the perforation 305. An upper circular plate 306 is slidably installed inside the cavity. The cavity is cylindrical and fits the upper circular plate 306. Multiple water outlet holes 303 are evenly provided on the outer wall of the piston body 302, which connect the cavity and the outside. Water entering from the perforation 305 flows into the upper layer through the water outlet holes 303 and can flow into the connecting pipe 401. The cylinder 2 is provided with a support frame 201. The support frame 201 is rotatably connected to the middle of the crank pressure rod 1. One end of the crank pressure rod 1 is rotatably connected to the connecting rod 301. The other end of the crank pressure rod 1 is used for manual pressing / lifting to make the piston part 3 slide up / down as a whole. The piston part 3 also includes a disc-shaped check valve 309. The bottom of the cylinder 2 is provided with a through hole 207. The inner wall of the bottom of the cylinder 2 is rotatably provided with a check valve 309 that can cover the through hole 207. The bottom of the check valve 309 is fixedly provided with a water inlet pipe 204, which is connected to the inside of the cylinder 2 through the through hole 207. During operation, pressing down the crank lever 1 causes the piston outer body 302 to move upward under the influence of the connecting rod 301. At this time, the air pressure between the piston outer body 302 and the bottom of the cylinder 2 decreases, the check valve 2 309 flips upward, and the upper disc 306 is pressed tightly against the bottom of the cavity. Groundwater then enters the space between the piston outer body 302 and the bottom of the cylinder 2. When the crank lever 1 is lifted upward, the piston outer body 302 moves downward, the check valve 2 309 closes, and the upper disc 306 moves upward (relative to the piston outer body 302). Groundwater enters the upper layer through the perforation 305, and during the next lifting of the piston outer body 302, the groundwater is sent into the connecting pipe 401. A main water outlet pipe 205 is installed through the outer wall of the cylinder 2 near the top. A flow meter 206 is installed on the main water outlet pipe 205. The main water outlet pipe 205 is used to collect more groundwater for other uses.

[0023] Working principle: The water inlet pipe 204 is inserted into the preset groundwater borehole. Groundwater is extracted by pressing the crank lever 1. The groundwater enters the water storage tank 404 through the connecting pipe 401, and then flows into each test bottle 1103 through the water storage tank 404. The test results are transmitted to the control unit 10 and then displayed on the display screen of the control unit 10.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
