The existing sampling barrels and bottles cannot realize automatic collection of water samples, which brings great inconvenience to water quality monitoring. Although China has designed a variety of automatic sewage sampling devices for this situation, the working principle is mostly to use pump sampling. This device is expensive and not easy to equip to various inspectors. It is also easy to get clogged and the daily maintenance workload is large. Summary of the invention

[0012] 1. The sampling bottle is equipped with an extended water inlet pipe with a counterweight to ensure that the water inlet point is close to the middle water level, so that the collected water sample is representative.

[0028] This 24-hour automatic sampling device in the underground mine includes the following work contents in actual application:

[0029] Step 1: The operator first sets the length of the collection rope 10 connected to the top of the sampling bottle 8. The collection rope 10 is generally required to be long enough to adapt to use in different occasions. The collection rope 10 is placed in the well, one end is connected to the equipment, and the other end is immersed in water. The collection rope 10 is pulled up and tied at about 10CM-50CM below the soaked part to ensure that the lock of the sampling bottle 8 cannot pass through. The operator installs the connectors of 18 groups of sampling bottles 8 on the automatic rotating table 1, arranges them in a clockwise direction in front of the baffle, and buckles the lock of the sampling bottle 8 on the collection rope 10 in the principle of first down and then up, and checks whether the lock can pass through the knot of the collection rope 10;

[0030] Step 2: Open the movable hook 9 connected to the hanging rod 6, pass through the two hooks of the sampling device, and then install the movable hook 9 of the hanging rod 6, open the sewage well cover and install the hanging net, put the sampling device into the sewage well, hang it on the hook of the safety net through the movable hook 9 of the hanging rod 6, close the sewage well cover, open the locator 11 and the battery 16 inside the protective shell 4;

[0031] Step 3: The operator sets the time requirements of the two groups of microcomputer time switches 15 respectively, both of which are started once every two hours and powered on for 1 minute each time, but one group of microcomputer time switches 15 runs one minute earlier than the second group of microcomputer time switches 15, and the battery 16 supplies power to the top of the automatic rotating table 1, so that the automatic rotating table 1 drives the equipment to rotate, thereby automatically driving and switching the equipment;

[0032] Step 4: 18 guide slots 3 are provided for installing the sampling bottle 8. Driven by the motor, the connector of the sampling bottle 8 is automatically rotated to the electric telescopic rod 5. The baffle of the protective shell is used to limit the rotation position. The sampling bottle 8 is pushed by the electric telescopic rod 5 to make the sampling bottle 8 disengage from the guide slot 3 and fall onto the automatic rotating table 1. The sampling bottle 8 is provided with a collection tube 13 with a counterweight to ensure that the water inlet point is close to the middle water level so that the collection tube 13 injects the liquid into the interior of the sampling bottle 8. The sampling bottle 8 mainly adopts the method of natural gravity sedimentation to inlet water. The water inlet is not allowed to be blocked. A check valve 12 is provided on the upper end of the sampling bottle 8 to release air when inletting water to facilitate water inlet and prevent water sample loss during collection.
