Anti-toppling water sampler

The invention belongs to the technical field of water quality sampling equipment, and particularly relates to an anti-toppling water quality sampler which comprises a floating plate, a control mechanism is fixedly connected to the upper surface of the floating plate, a sealing cover is fixedly connected to the upper surface of the floating plate, a storage battery assembly is fixedly connected to the inner wall of the sealing cover, and a through hole is formed in the top end of the sealing cover. The water quality sampler has an automatic inclination correction function, it is guaranteed that the water taking part of the water quality sampler can accurately sample at the target sampling depth, the water quality sampler further has an anti-toppling function in the sample taking-out process, toppling damage of the water quality sampler can be avoided, the situations of water sample leakage and pollution can be avoided, and the water quality sampler is convenient to use. And the water quality sampler also has t
