Water body sampling device based on unmanned ship and use method of water body sampling device

Abstract

The invention discloses a water body sampling device based on an unmanned ship and a use method thereof. The water body sampling device comprises the unmanned ship, an electric cylinder is installed on the unmanned ship, the bottom end of a piston rod of the electric cylinder is connected with a sampler, the sampler comprises a supporting plate, and the bottom of the supporting plate is connected with an obliquely-arranged U-shaped frame. A protection cylinder is hinged to the U-shaped frame through a pin shaft. A sampling pipe is mounted in the protective cylinder in a sleeving manner, a cushion block is connected to one side of the U-shaped frame, and when the protective cylinder is attached to the surface of the cushion block, the protective cylinder is inclined; the U-shaped frame is connected with a magnet piece, and when the protection barrel is attracted to the surface of the magnet piece, the protection barrel is in a vertical shape. The device also includes a baffle plate. The top of the baffle plate is connected with the supporting plate; a blocking plate is slidably connected to the surface of one side of the baffle plate, and when the protection barrel is in a vertical shape, the blocking plate is pressed at the center hole, so that blocking of the center hole is achieved. The whole sampling process is easy to operate, efficient and intelligent, the sampling pipe can automatically rotate and seal, manual control is not needed, the structural design is ingenious and reasonable, and use is very convenient.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water body sampling device based on an unmanned ship and a use method thereof. Background technique [0002] Water sample collection is an important link in the work of water quality monitoring and hydrological measurement for environmental protection. It is not a simple collection of water samples, because the water samples provided for analysis must be representative in order to accurately reflect the concentration and indicators of water quality parameters. There are many factors that affect the collection of water samples, such as sampling points, sampling instruments, sampling volume, sampling methods, and even storage of water samples. Changes in any of these factors may lead to changes in the analysis results. Therefore, how to make the collected water samples truly and accurately reflect the water quality is the first problem that must be solved i...

Problems solved by technology

At present, the sampling methods include automatic sampling and manual sampling. The two sampling methods have their own advantages and disadvantages. Traditional manual sampling usually uses sampling buckets or sampling bottles, which have the advantages of low cost and relatively simple, but there are Disadvantages of time-consuming and labor-intensive and potential safety hazards; automatic sampling devices on the market have appeared based on unmanned aerial vehicles to complete the sampling work, which has the advantages of high automation, time-saving and labor-saving advantages, but it has the following disadvantages: First, the use of unmanned Machine sampling requires high cost, high cost, and inconvenient daily maintenance. It is difficult for a general-scale water sample testing organization to afford the high cost; secondly, the water body sampling drone samples the water body through the hanging sampling bottle The opening of the bottle is facing upwards. Since the sampling bottle lacks an automatic sealing structure, some garbage in the water may enter the sampling bottle; in addition, the water in the sampling bottle is very easy to scatter when it moves with the drone. The volume of samples is different, and the purpose of quantitative sampling cannot be achieved, making the collected samples unrepresentative; in addition, the existing drones still have the problem of inconvenient loading and unloading of sampling bottles, which affects work efficiency
