As optimization, the rubber membrane at described blockage sensing device 1.4 two ends is by the threaded pressure ring fixing seal matching with column insulation crust both ends open place internal thread; Can for convenience detachly adjust as required pushing block position, and then adjust the sensitivity of blockage sensing device.
As optimization, described central controller is provided with corresponding state indicator lamp and buzzer. Can reflect in real time water level or blocked state, even if be convenient for people to process corresponding failure.
As optimization, described water pump 2 is self priming pump.
Described inner tube 1.1 and outer tube 1.2 are realized sealing socket by being separately positioned on the sealing ring of inner tube 1.1 ends and outer tube 1.2 ends, as rubber seal; The sealing ring of described inner tube 1.1 ends is nested on the cannelure of inner tube 1.1 periphery walls, and the sealing ring of described outer tube 1.2 ends is embedded on the cannelure of outer tube 1.2 internal perisporiums; This structure can facilitate outer tube 1.2 to be unlikely to again to come off with respect to inner tube 1.1 free-extensions; Because buoyancy is greater than the suffered gravity of outer tube, therefore in the time that well middle water level declines or raise, can ensure that the length that outer tube 1.2 is immersed in water in certain flexible scope keeps certain, can make like this hydraulic pressure that the rubber membrane of described blockage sensing device 1.4 is subject to keep compared with stationary value, guarantee the water intaking degree of depth of bailing pipe 1, guaranteed again precision and the job stability of blockage sensing device 1.4.
As shown in Figure 5, a kind of method that adopts the above-mentioned water system for well to supply water:
1) water storage box 3, filter 7 and buffer container 8 are arranged on roof, vertical inner tube 1.1 water surface is fixed on to well central authorities; Outer tube 1.2 vertically stretches into the water surface to floating block 1.5 and contacts with the water surface; Then start and initialize central controller, water pump 2 states are initialized as closes; The state of magnetic valve 5 is initialized as closes;
2) central controller detects the 3rd water level sensor 3.2 states, if the electrode of the 3rd water level sensor 3.2 is in off-state, be that water storage box 3 water levels are too low, opens solenoid valve 5 and water pump 2, and constantly detect the state of blockage sensing device 1.4, the first water level sensor 1.3, the second water level sensor 3.1; When blockage sensing device 1.4 electrode closures, stopping up appears in outer tube 1.2; Or the first water level sensor 1.3 electrodes disconnect, and the water source water surface is too low; Or the second water level sensor 3.1 electrode closures, water storage box is full; Switch off the pump 2 and magnetic valve 5;
3) repeating step 2).
Below be only that feature of the present invention is implemented example, protection domain of the present invention is not constituted any limitation. The equal exchange of all employings or equivalence are replaced and the technical scheme of formation, within all dropping on rights protection scope of the present invention.
