Diversion canal water body multilayer plant propagule sampler for mountain river diversion power station

The utility model relates to a diversion canal water body multilayer plant propagule sampler for a mountain river diversion power station. The diversion canal water body multilayer plant propagule sampler comprises at least one sampling unit. Each sampling unit comprises a splicing vertical rod and a movable filtering device, and the movable filtering device is detachably installed with the splicing vertical rod and is arranged on the splicing vertical rod. The sampling units are connected through the splicing vertical rods. A plurality of sampling units can be spliced according to the implementing requirements through the connection of the splicing vertical rods, so as to achieve the needed length; and in theory, the sampling units can be suitable for all the water depths and even can be prolonged infinitely. Each movable filtering device is of an independent structure and can also be increased infinitely through movable clamps. The diversion canal water body multilayer plant propagule sampler can conveniently and quickly perform in-situ sampling on propagules of different layers of the diversion canal water body of the mountain river diversion power station.
