Description

Technical Field

[0002] Surface water refers to the general term for dynamic water and static water on the land surface, also known as "land water", including various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, ice sheets, etc. It is one of the important sources of water for human life. In order to ensure the water quality safety of surface water, it is often necessary to sample and test the water quality of relevant waters. Since traditional manual sampling is time-consuming and labor-intensive and has certain operational risks, unmanned sampling ships are now used instead of manual sampling for water quality sampling.

[0003] At present, most sampling vessels use two water inlet pipes to sample two water areas. The number of samples is small, which means that when sampling in multiple areas, the sampling vessel needs to return to land to replace the sample bottle and then set out again to sample, which is inconvenient to operate. Therefore, an automatic surface water sampling vessel is urgently needed. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, the present invention sets a first water inlet pipe, a solenoid valve, a flushing pipe and a sample bottle, and a first motor controls the water pumping pipe to open to sample the water body. By opening the solenoid valves on different first water inlet pipes, the extracted samples enter different sample bottles respectively through the first water inlet pipe, the hose, the first connecting pipe and the second connecting pipe. Sampling can be performed at four different positions to improve the sampling efficiency. Before starting sampling, the water in the clean water tank backwashes the delivery pipe, the bellows and the water pumping pipe to eliminate the residue of the previous sampling, thereby not affecting the original condition of the water body for the next sampling.

[0019] Second, the present invention sets a first water spray ring, a second water spray ring, a high-pressure nozzle and a high-pressure water pipe. After the sampling is completed, the first motor drives the water extraction pipe to be retracted into the storage tank through the driving rod. At this time, the second water pump and the booster pump on the high-pressure water pipe are controlled to operate. After the high-pressure water pipe extracts water from the water body, it is pressurized and the high-pressure water flow enters the first water spray ring and the second water spray ring, and is sprayed out through multiple high-pressure nozzles to flush the outer wall of the water extraction pipe, so that aquatic plants, impurities and other items are washed down by the high-pressure water flow under the influence of the buoyancy of the water body, and thus fall into the water body, ensuring that the outside of the water extraction pipe is clean.

[0020] Third, the present invention provides an extension rod, a sampling tube, a sampling head, a sampling slot and a baffle. When it is necessary to sample the sediment at the bottom of the water body, the extension rod is fixedly connected to the sampling tube through a threaded seat in advance, and the tooth grooves on the outer wall are aligned. At this time, the second motor is controlled to operate to drive the gear at the output end to rotate. When the gear rotates, it engages with the tooth groove and drives the sampling tube and the extension rod to move vertically downward on the inner side of the support sleeve until the sampling tube is inserted into the sediment. At this time, the third motor is controlled to operate to drive the winding roller at the output end and The rope is reeled in, and the baffle is driven by the tension of the rope to move up on the inner side of the limit frame, thereby exposing the sampling slot, and the sediment can enter the sampling slot. At this time, the third motor drives the winding roller and the rope to unwind, and the baffle falls down by the deadweight of the counterweight, and finally seals the sampling slot. At this time, the second motor drives the gear to reverse, thereby driving the extension rod and the sampling tube to move up, so that the sampling tube returns to the inner side of the movable slot. When the hull returns to land, the sampling head can be screwed to separate it from the sampling tube, making it easier to take out the sample. BRIEF DESCRIPTION OF THE DRAWINGS
