Preferably, the floating body is inflatable elastic hollow sphere, buoyancy size can be adjusted as needed.
Preferably, the length of the traction rope is adjustable, by changing the length of traction rope, to control water intaking depth.
After the length for regulating traction rope, that is, it can determine water intaking depth, after device for fetching water is devoted in water, device for fetching water ontology
Sink under the effect of gravity, floating body floats on the surface, and as device for fetching water gradually sinks, traction rope can be tensed gradually, is drawing
Under the pulling force effect of rope, the steel ball of upper water valve and the next water valve has been pulled upwardly, at this point, upper water valve and the next water valve are beaten
It opens, water enters water taking cavity by enterprising exhalant canal and lower disengaging aquaporin, and then enters water storage cavity, after the completion of water intaking, passes through
Hanging ring leaves the water device for fetching water ontology, after steel ball loses the pulling force of traction rope, is restored under the action of reset spring initial
Position, upper water valve and the next water valve are in closed state at this time, and the water taken will not leak out；Pull traction rope that can will fetch water
Water in device is released.
The beneficial effects of the present invention are:
The configuration of the present invention is simple, it is easy to use, it can be achieved that automatically taking water, it can also realize and fetch water at the depth of water of needs,
And depth of fetching water is adjustable.
