Detailed Description

The utility model is further described below with reference to the accompanying drawings:

Referring to the drawings: the water quality sampler comprises a sampling barrel 1 and a lifting rope 2, wherein a sampling cavity 3 is arranged on the upper portion of the sampling barrel 1, an electric rotary index plate 4 is arranged in the sampling cavity, a plurality of positioning grooves 5 are uniformly distributed on the electric rotary index plate 4 in the circumferential direction, and a sewage collecting groove can be further formed in the electric rotary index plate 4 and used for receiving a small amount of leaked sewage. The positioning groove 5 is internally provided with a sampling tank 6, the top of the sampling tank 6 is provided with a tank opening 7, the tank opening 7 is provided with a rubber check valve 8, the top of the sampling cavity is provided with a detachable sealing bin cover 9, the sealing bin cover 9 is provided with a sampling opening 10 corresponding to the position of the sampling tank 6, the sampling opening 10 is provided with an electric water inlet valve 11 for sampling, and an elastic sealing ring 12 is arranged between the sampling opening 10 and the tank opening 7. The downside of sampling mouth 10 is equipped with the seal groove, fixed mounting on the seal groove elastic sealing ring 12, and elastic sealing ring 12 can contact the upside surface of sampling jar 6 and realize sealedly, makes the water in the sampling mouth 10 be difficult for leaking to the jar body outside.

Working principle: when the sampling is needed, the sampling barrel 1 is placed in a water area to be sampled, a worker or a lifter grabs the lifting rope 2 to place the sampling barrel 1 in the water area, the sampling barrel 1 sinks under the action of self gravity, the sinking process can be determined according to the sinking length of the lifting rope 2, after the sinking depth reaches the first sampling depth, the electric water inlet valve 11 is opened to enable the sampling port 10 to be conducted, so that a water sample can enter the sampling barrel 1 through the sampling port 10 and is led into the sampling tank 6 through the rubber check valve 8, and then the electric water inlet valve 11 is controlled to be closed. When the sinking depth reaches the second sampling depth, another sampling tank 6 is required to be selected for sampling, the electric rotary index plate 4 is started to rotate for indexing, a new sampling tank 6 is replaced below the sampling port 10, the elastic sealing ring 12 plays a sealing role, a large amount of water can be prevented from leaking, the sampling operation is repeated once, the sampling barrel 1 is pulled out through the lifting rope 2, the bolts are disassembled, the sealing bin cover 9 is turned over, and the sampling tank 6 is taken out of the extracted water body for sampling detection.

The bottom of sampling chamber is equipped with and is used for electric telescopic handle 13, the bottom of constant head tank 5 is equipped with the central through-hole 14 that electric telescopic handle 13 passed through. During sampling, the electric telescopic rod 13 can extend to penetrate through the central through hole 14 to jack up the sampling tank 6, so that the sampling tank is pressed onto the elastic sealing ring 12, the sealing effect is enhanced, and after sampling is finished, the electric telescopic rod 13 is retracted below the central through hole 14.

When more than two sampling ports 10 are provided, a filter screen 15 may be installed on one of the sampling ports 10, so as to facilitate the simultaneous collection of the filtered samples and the samples without filtration. A sampling tank is specially selected as a sewage tank to receive sewage, the quality of collected samples of a general head section is poor, the collected samples need to be discarded, and the collected samples can be collected by the sewage tank and then replaced by the sampling tank. If the sampling precision is to be improved, a cleaning device can be additionally arranged in the sampling port 10, and the inner wall after sampling is flushed with clear water by using a spray head, so that the problem of cross contamination between samples can be further avoided.

The pressure sensor 16 is fixedly installed on the sealing bin cover 9, the pressure sensor 16 can detect the pressure borne by the sampling bucket 1 and calculate the sinking depth according to the water pressure, the pressure sensor 16, the electric rotary index plate 4 and the electric water inlet valve 11 are electrically connected to the control module 17, the control module 17 is connected with an external remote controller through a wireless communication module in a wireless mode, a worker monitors the submerging depth of the sampling bucket 1 through a display screen on the remote controller, and then a mode of sampling operation is selected manually or automatically through the remote controller.

While the utility model has been shown and described with reference to a preferred embodiment, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the utility model.
