Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figure 1, a water quality sampler for environmental monitoring includes a bracket 1, a sampling bottle 2 and a sampler body 3, the lower end of the bracket 1 is connected to the sampler body 3, and the sampling bottle 2 is suspended and connected to the bracket 1 , further, the sampler body 3 is movably connected to the bracket 1, the bracket 1 is a telescopic and movable triangular bracket, and the sampling bottle 2 is suspended on the bracket 1 through a suspension rope 11. The bracket 1 is detachable and telescopic, which reduces the transport volume, and at the same time does not need to counterweight the sampler body 3, which is used to overcome the buoyancy of the hollow container when it enters the water, greatly reducing the empty weight.

As shown in Figure 1, several isolated sampling cavities 21 are arranged in the sampling bottle 2, and the water outlet 22 of each sampling cavity 21 and the water outlet 22 sealingly connected with the water outlet 22 are provided on the side wall of the sampling bottle 2. Sealing cover 23, the sampler body 3 includes water inlet pipe 4, submersible pump 5, controller 6, water pressure sensor 7, sampling tube 8 and battery 9, one end of the sampling tube 8 collects water samples, and the other end is connected to the submersible After the pump 5 is connected with one end of the water inlet pipe 4 through a pipeline, the other end of the water inlet pipe 4 is sealed and passed through the sampling bottle 2 and is provided with a bifurcated sealing switch valve 41 extending to each sampling chamber 21. The control The controller 6 is electrically connected with the water pressure sensor 7, the submersible pump 5, the battery 9 and each switch valve 41, and the controller 6 controls the opening of one of the switch valves 41 at different depths.
