[0015] Compared with the prior art, the utility model provides an algae sample extraction device in water, which has the following beneficial effects:

[0016] 1. The utility model sets a driving shaft, which is fixedly connected to the rotating shaft of the driving motor. The driving shaft is rotatably connected to the outer shell through a connecting bearing, and the gear and the driving shaft are fixedly connected. At the same time, the outer gear of the limit shaft and the outer gear of the driving shaft are meshed with each other. When the driving motor is started, the driving shaft can be driven to rotate, thereby driving the gear to rotate. When the gear rotates, the air on the front side of the inner cavity of the outer shell can be moved to the rear side, so that a vacuum is formed in the front cavity of the outer shell. When sampling, the water inlet needs to be located near the algae through a receiving tube, and the external air pressure will cause water to flow in. Inside the water inlet, the algae are driven into the water outlet by the water flow, and the position of the algae is limited by the metal mesh. This method can reduce the damage to the algae.

The position of the metal mesh will be restricted during the tightening of the water inlet. After the drive motor is started, when the water inlet is located in the water, the water flow will drive the algae and sand and gravel particles floating in the water into the water inlet. Since the mesh size of the metal mesh is eight millimeters, the metal mesh can intercept the algae and allow dust and sand to pass through the water inlet. The sand and gravel will be intercepted by the filter element when passing through the filter element driven by the water flow. This method can reduce the sand and gravel content in the sample, and the algae sample can be rinsed by water flow to prevent sand and gravel from mixing into the algae sample.
