The different height portions of a suspended fine rope are provided with two objects which can generate gravity and buoyancy to change the water level height into the gravity strength. The utility model conducts corresponding actions by the fine rope is applied on a structure, such as the monostable switch of a travel switch to directly or indirectly control the closing and the starting of the water pump. The device has very simple structure, safe and reliable use, convenient upper limit and lower limit regulation, convenient installation, repair with low cost and is a practical device with high cost performance. In particular, the excellent property can be displayed if the utility model is used for the water well whose depth is more than a dozen meters.
Description
The utility model relates to feedwater, draining field, is particularly suitable for a kind of monostable switch formula water level controller.
People once designed a lot of water level automatic control devices, as electronic switching circuit, the time relay with mechanical water level controller etc., but because of they cost an arm and a leg, reason such as installation and maintenance inconvenience or performance are bad applies being restricted.
The open CN1045620A of Chinese invention patent application, be to overlap the float that can fluctuate on a pipe, the stop means with gauge tap interlock is equipped with in the top and bottom of pipe, utilize float about, drive stop means, and then interlock gauge tap break-make.The weak point of this device is that inconvenience is highly regulated in control.
China utility model application bulletin CN2065632U, be the location slip ring to be housed with a sidepiece, the pole of float is equipped with in the bottom, slide up and down with water level along the exceptionally straight messenger wire that passes the location slip ring by buoyancy and gravity, affect the tightrope that is connecting masthead and knife switch handle with this, drive the knife switch folding by tightrope, remove to control water pump and draw water.The weak point of this device is that its knife switch very easily is in a kind of state like Tong Feitong.
The purpose of this utility model exactly for overcoming many deficiencies of water level controller in the past, provides a kind of control reliably, adapt to wide, and water level controller simple in structure, cheap.
