In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the timing-interval continuous automatic water sampling device comprises a power system, a control system and a water storage device, wherein the water storage device comprises a rectangular groove, a plurality of partition plates are arranged in the rectangular groove in a criss-cross manner, and the inner cavity of the rectangular groove is divided into a plurality of accommodating grooves for accommodating water sample bottles by the partition plates; the power system comprises a water pump unit, a water taking pipe, a water conveying pipe, tee joints which are arranged in one-to-one correspondence with water sample bottles, water distribution pipes which are arranged in one-to-one correspondence with the tee joints, and electromagnetic valves which are arranged in one-to-one correspondence with the water distribution pipes, wherein the input end of the water pump unit is communicated with the tail end of the water taking pipe, the output end of the water pump unit is communicated with the head end of the water conveying pipe, the first interface and the second interface of the tee joints are communicated with the inner cavity of the water conveying pipe, the third interface of the tee joints is communicated with the head end of the water distribution pipes, and the tail end; the electromagnetic valve is used for controlling the on-off of fluid in the water diversion pipe; the control system comprises a relay for controlling the electromagnetic valve, and the relay is controlled through a PLC instruction.
According to the invention, a water sample is collected into a water sample bottle at regular time-interval by taking a time period as a unit. If a water sample is taken every 1 hour for 24 hours a day, 24 water sample bottles need to be prepared. Firstly, the time required for taking a full water sample is checked, if 1 minute is required, the PLC is programmed, the sample is taken once at 1 point, the system stops working if the sampling lasts for 1 minute, the system is restarted at 2 points, the sampling lasts for 1 minute, the system is closed, and the steps are sequentially carried out.
