[0022] The present invention also provides a method for using a portable box-type water quality detection device, comprising the following steps:

[0023] Step 1: Move the drawbar box to the sampling inspection location by pulling the telescopic rod and sliding the outer pulley. Then square the drawbar box and open the buckle. Then flip the left box open through the hinge and place it on the ground.

[0024] Step 2: Control the micro motor to drive the reel to release the short water pumping tube through the bevel gear set. At the same time, manually pull out the water pumping filter and drag the water pumping hose out of the right box body. Then, place the water pumping filter and the water pumping hose into the water body. When the water pumping hose is released to the appropriate length, control the micro motor to stop working.

[0025] Step 3: Control the pumping solenoid valve and the filter solenoid valve to open, and control the diaphragm pump to work, so that the water sample in the water body passes through the pumping filter - pumping hose - pumping short pipe - rotary joint - L-shaped pumping pipe - L-shaped short pipe into the diaphragm pump, and through pumping, the water body is injected into the cleaning water tank through the L-shaped delivery pipe - filter pipe, and filtered through the filter element at the same time;

[0026] Step 4: When the clean water in the cleaning water tank reaches a certain amount, the filter solenoid valve is closed and the water inlet solenoid valve is controlled to open. At this time, as the diaphragm pump pumps, the water is injected into the test bottle through the L-shaped delivery pipe-quick-connect hose-water inlet pipe and stored in the test bottle. When the water is injected to a certain amount, the diaphragm pump is controlled to stop working;

[0027] Step 5: Control the water quality detector to start working, so that it detects the water sample inside the detection bottle through the detection probe and stores the detection results;

[0028] Step 6: Take out the sample bottle and open it, then pull out the telescopic hose and insert it into the sample bottle, then control the sample solenoid valve to open, and control the diaphragm water pump to work, so that the water sample inside the test bottle is injected into the sample bottle through the discharge pipe-L-shaped branch pipe-telescopic hose for sample retention. After the sample is retained, cover the sample bottle and put it back into the sample bottle slot, and close the sample solenoid valve and diaphragm water pump;

[0029] Step 6: Control the clean water solenoid valve and the discharge solenoid valve to open, and control the diaphragm water pump to work, so that clean water is injected into the test bottle through the clean water discharge pipe-diaphragm water pump-L-type delivery pipe-quick-connect hose-water inlet pipe, and then discharged back into the water body through the discharge pipe-quick-connect hose-L-type water pipe-swivel joint-water short pipe-water hose to clean the inside of the device;

[0030] Step 7: Control the diaphragm water pump to stop working, and control the water discharge solenoid valve to open, and then control the micro air pump to work, so that it injects air into the cleaning water tank, and through the action of air pressure, completely pushes out the clean water, so that the clean water is injected into the test bottle through the clean water discharge pipe-L-type delivery pipe-quick-connect hose-water inlet pipe, and then discharged to the outside through the discharge pipe-quick-connect hose-L-type water suction pipe-swivel joint-water suction short pipe-water suction hose to drain the residual water inside the device.

[0031] Step 8: Control all solenoid valves to close, turn off the micro air pump, and then control the micro motor to work in reverse, so that it drives the reel to reel up the water suction hose, and until the water suction filter is stored in the filter mouth, the micro motor can be controlled to stop working. Finally, flip the left box body over and buckle it on the right box body, and lock it with a buckle, and then stand up the pull rod box body.

[0032] Beneficial effects

[0035] 2. The shape of the detection bottle can be used to enable the detection probe to sample water samples on the one hand, and on the other hand, the internal samples can be quickly discharged, thereby facilitating the cleaning of the detection bottle and ensuring the detection accuracy during multiple tests.

[0079] During the implementation of this technical solution, personnel in this field need to connect all electrical components in this case to an external power supply mechanism, and should select a suitable controller according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0080] When specifically using the present invention, adopt the following steps:

[0081] Step 1: After the drawbar box 1 is moved to the sampling and testing location by pulling the telescopic rod 121 and sliding the outer pulley 14, the drawbar box 1 is squared and the buckle is opened. Then, the left box 11 is flipped open by the hinge 13 and placed on the ground.

[0082] Step 2: Control the micro motor 213 to drive the reel 211 through the bevel gear set to release the short water pumping tube 214. At the same time, manually pull out the water pumping filter 123 and drag the water pumping hose 217 out of the right box 12. Then, place the water pumping filter 123 and the water pumping hose 217 into the water body. When the water pumping hose 217 is released to the appropriate length, control the micro motor 213 to stop working.

[0083] Step 3: Control the pumping solenoid valve 237 and the filtering solenoid valve 232 to open, and control the diaphragm pump 223 to work, so that the water sample in the water body passes through the pumping filter 123-the pumping hose 217-the pumping short pipe 214-the rotary joint 215-the L-shaped pumping pipe 216-the L-shaped short pipe 236 into the diaphragm pump 223, and through pumping, the water body is injected into the cleaning water tank 23 through the L-shaped delivery pipe 224-the filter pipe 231, and is filtered by the filter element 233 at the same time;

[0084] Step 4: When the clean water in the cleaning water tank 23 reaches a certain amount, the filter solenoid valve 232 is closed and the water inlet solenoid valve 178 is opened. At this time, as the diaphragm pump 223 pumps water, the water is injected into the detection bottle 17 through the L-shaped delivery pipe 224, the quick-connect hose 24, and the water inlet pipe 171, and is stored in the detection bottle 17. When the water is injected to a certain amount, the diaphragm pump 223 is controlled to stop working.

[0085] Step 5: Control the water quality detector 15 to start working, so that it detects the water sample inside the detection bottle 17 through the detection probe 177 and stores the detection result;

[0086] Step 6: Take out the sample bottle 181 and open it, then draw out the telescopic hose 176 and insert it into the sample bottle 181, then control the sample solenoid valve 175 to open, and control the diaphragm water pump 223 to work, so that the water sample inside the detection bottle body 17 is injected into the sample bottle 181 through the discharge pipe 172-L-shaped branch pipe 174-telescopic hose 176 for sample retention. After the sample retention is completed, cover the sample bottle 181 and put it back into the sample bottle slot 18, and close the sample solenoid valve 175 and the diaphragm water pump 223;
