Embodiment Construction

[0010] 1. Input the coordinates of the specified sampling point into the storage device of the sampling ship before sampling;

[0011] 2. Set up 2 or more GPS base stations at high places on the shore, and input the location coordinates of the base stations;

[0012] 3. Put the numbered and cleaned sampling bottles into the sampling ship in the specified order;

[0013] 4. After debugging the sampling ship, put the ship on the water surface and turn on the power;

[0014] 5. The sampling ship receives the GPS base station signal through the GPS receiver on board and calculates the position of the ship, and then drives the ship to the designated position by the power and control mechanism;

[0015] 6. After the ship sails to the designated position, it stops at the designated sampling point, and then the power and control mechanism of the winch releases the water hose to the designated depth, and the hose will be kept vertically downward under the action of counterweight gravi...

Abstract

The invention provides an automatic fixed-point fixed-depth water sampler (as shown in a figure 1). The automatic fixed-point fixed-depth water sampler mainly comprises an onshore GPS base station anda sampling ship, wherein the sampling ship is composed of a propeller, a propeller powering and controlling mechanism, a hull, a water sample bottle, a water outlet device and a controller, a battery, a pump, a GPS receiver, ship storage equipment, a capstan controlling and powering mechanism, a capstan, a water sampling hose and a hose counterweight. In use of the water sampler of the inventionsampling personnel only needs to set the GPS base station and input the coordinates of a sampling point and water depth into a sampling ship memory card, and then the sampling ship automatically sailsto a designated position through spatial positioning and extracts a water sample at a designated depth; so sampling efficiency is greatly improved and the safety of the sampling personal is guaranteed.

Description

technical field [0001] The invention relates to the field of water quality monitoring of lakes, reservoirs, rivers and the like, in particular to an automatic fixed-point and fixed-depth water fetcher. Background technique [0002] In the water quality monitoring of reservoirs, lakes, rivers, etc., it is often necessary to carry out fixed-point stratified sampling of water bodies, but at present, manual sampling is still the main method of water body sampling. Manual sampling requires ships to transport people to designated locations in the water body, and then the sampling personnel take samples of the water body layer by layer. Manual sampling requires large ships and manual support, which has low efficiency and poor accuracy, and it is difficult to sample in the case of rough wind and high waves to avoid endangering the personal safety of sampling personnel. With the development of automation technology and the support of GPS space positioning, there is no technical diff...
