Background technology
See also shown in Figure 1, when it is certain office building foundation construction, for underground water table is dropped to construction precipitation process flow diagram below the 10m from 2.45m, its main process flow is: water pump → drainage pipeline laying → energized gang of wells turn on pump precipitation is installed in the gang of wells pipe well construction → well, but because well pump is more, manually be difficult to control the open and close of well pump, cause water pump often to open existing problems, and following situation occurs:
1, the unloaded power consumption of water pump;
2, water pump abnormal waste;
3, after water pump damages, more time-consuming, the effort of water-change pump, influence precipitation.
The utility model content
In view of this, the fundamental purpose of the utility model water level auto-controller is to solve according to the water level depth, the device of automatic control switch WIH pump.That is: in construction precipitation process, when the WIH pump draws water, when the well water position drops near shaft bottom submersible pump water inlet assigned position (actual can be 20m), the water pump pump trip, after water pump stops, slowly rise in the WIH position, (actually can be 10m when water level rises to when height expection, be the degree of depth of well water position control), the automatic turn on pump of water pump draws water, and water level begins again to descend, and goes round and begins again, reach the automatic switch pump, control the purpose of underground water table automatically.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of water level auto-controller, include control circuit and water pump, control circuit is the series circuit that power supply, transformer, first rectifier, audible alarm, pilot lamp, little relay, water level lead, ground wire, second rectifier are in turn connected to form, little relay connects a big relay, big relay one end connects power supply, and the other end connects water pump;
The water level lead is the parallel branch that high water stage lead and low-water level lead are formed, and the high water stage lead is arranged at the high water stage place that needs in the enforcement precipitation well, and the low-water level lead is arranged at the low-water level place that needs in the enforcement precipitation well.
Adopt the technique effect of the technical solution of the utility model to be: can reduce power load and labour intensity greatly, feasible construction is felt more relieved, and underground water table below the foundation ditch bottom, has guaranteed carrying out smoothly of foundation construction all the time, guarantee construction quality, made construction precipitation expense save greatly.
Description of drawings
The construction precipitation process flow diagram of Fig. 1 for using in the prior art;
Fig. 2 obtains the circuit connection diagram of water level signal for the utility model water level auto-controller;
Fig. 3 loses the circuit connection diagram of water level signal for the utility model water level auto-controller;
Fig. 4 utilizes the circuit theory diagrams of water level signal control pump working for the utility model water level auto-controller.
Embodiment
The utility model water level auto-controller is the lead that setting obtains water level signal in the well of needs enforcement precipitation, and the opening and closing that utilize water level signal control water pump again are to realize the automatic control of precipitation.
For making the auditor know composition of the present utility model, and embodiment, cooperate graphic being described as follows now:
See also Fig. 2 and shown in Figure 3, the circuit connection diagram that it is obtained water level signal and lose water level signal for the utility model water level auto-controller, this control circuit is a power supply 1, transformer 2, first rectifier 3, audible alarm 4, pilot lamp 5, the water level lead, ground wire 8, the series circuit that second rectifier 9 is in turn connected to form, the water level lead is the parallel branch that high water stage lead 6 and low-water level lead 7 are formed, wherein, high water stage lead 6, low-water level lead 7 and ground wire 8 place the well water end that electrode 10 is installed, the high water stage lead is arranged at the high water stage place that needs in the enforcement precipitation well, the low-water level lead is arranged at the low-water level place that needs in the enforcement precipitation well, and ground wire is arranged at the lowermost end of well.Transformer is converted to the 24V safe voltage with the 220V normal voltage, and first reorganizer 3 and second rectifier 9 are converted to direct current with alternating current, and entire circuit is able to UNICOM by the conduction property of well water.When well water is positioned at the high water stage place, the bright and audible alarm warning of pilot lamp.When well water drops to this low-water line when following, pilot lamp goes out and audible alarm quits work.
See also shown in Figure 4, it utilizes the circuit theory diagrams of water level signal control pump working for the utility model water level auto-controller, the utility model water level auto-controller further utilizes electromagnetic induction principle, adopt little relay to drive the method for big relay, control electrical source of power switch is controlled starting mode of pump or is stopped with water level signal.On the basis of foregoing circuit, the water level lead little relay 11 of connecting, little relay 11 connects a big relay 12, big relay 12 1 ends connect power supply 1, and the other end connects water pump, when obtaining water level signal, little relay drives big relay work, start water pump, when losing water level signal, water pump quits work.
Adopt the beneficial effect of the utility model water level auto-controller to be: first: reduced power load greatly, power load has reduced more than 80%; Second: greatly reduce labour intensity, labour intensity has reduced more than 80%; The 3rd: make construction feel more relieved, underground water table below the foundation ditch bottom, has guaranteed carrying out smoothly of foundation construction all the time, has guaranteed construction quality; The 4th: construction precipitation expense is saved greatly.
Above-mentioned technique effect can embody with following concrete enforcement engineering:
The former underground water level 2.54m of certain engineering foundation ditch, foundation pit dewatering project is reduced to below the about 8m of foundation depth underground water table.Base pit dewatering is totally 42 mouthfuls of wells, and manufactured 21 " water level autocontrol instrument " in the first batch and come into operation, 21 draught animals wells with not using " water level autocontrol instrument ", carried out effect comparison:
1) reduces water pump idle time: do not use the well of " water level autocontrol instrument ", water pump operation round the clock in a day 24 hours (precipitation reaches requirement in order to guarantee to construct); Use the well of " water level autocontrol instrument ", about about 60 minutes of average working time every day of pump; Avoided water pump every day unloaded about 23 hours.
2) reducing water pump damages: do not use the well of " water level autocontrol instrument ", because the water pump idle period is oversize, unloaded heating serious wear was damaged 23 times in 21 water pumps in one month; Use the well of " water level autocontrol instrument ", because water pump has been avoided zero load, 21 none damages of water pump.
The utility model structure is not limited to the described form of embodiment, be with, approximate with structure of the present utility model, device, feature etc. such as, identical person all should belong to the scope of founding purpose and applying for a patent of the present utility model.The further expansion that those of ordinary skill in the art makes according to the utility model all falls into scope of the present utility model.
