Abstract
The utility model discloses an automatic switch for water pumping of a water tower, which comprises a tripping device, a transformer T1, a bridge rectifying circuit, a control circuit and a test switch S. The tripping device is composed of a coil J and a contact switch J-K. The bridge rectifying circuit is composed of a diode D1, a diode D2, a diode D3 and a diode D4. The control circuit is composed of a controlled silicon T, a capacitor C, a resistor R, a probe A and a probe B. The automatic switch for the water pumping of the water tower is simple in structure, safe and stable in performance and low in production cost, and is mainly used for solving the problem that a water pump power supply is cut off in a hurry when water overflows during water pumping of the water tower in rural areas, thereby enabling the power supply to be automatically cut off after the water tower is full of pumped water, and saving electric power and water resource.
Description
Technical field
The utility model relates to a kind of electronic equipments field, is specifically related to a kind of water tower automatic switch that draws water.
Background technology
At present, the most of household waters in rural area are to supply with the pond that suction pump is irrigated by lifting water to a higher level with a water pump, etc. from well on water tower or the one-storey house, most time treats that it is just to turn off power supply in a great rush that water tower or pond Zhong Shui overflow when drawing water, this product is mainly used in and solves the rural area water tower and draw water and the problem that spilling water is just turned off the suction pump power supply often occurs, the water of realization water tower is taken out to expire and is just cut off the electricity supply automatically, reaches the purpose of saves energy and water resource.
Summary of the invention
For reaching the foregoing invention purpose, the technical scheme that is adopted is: comprise electrical apparatus release, transformer T1, bridge rectifier, control circuit and test switch S; Electrical apparatus release is made up of coil J and contact switch J-K; Bridge rectifier is made up of diode D1, diode D2, diode D3 and diode D4; Control circuit is made up of controllable silicon T, capacitor C, resistor R and probe A and probe B; Terminal 1 is connected the circuit of civil power AC220V with terminal 2, terminal 3 is connected transformer T1 primary coil and the external water pump M that draws water respectively with terminal 4; T1 level of transformer upper terminal 7, terminal 8 are connected with the negative pole of bridge rectifier input diode D1, the negative pole of diode D2 respectively; Coil J upper terminal 6 connects bridge rectifier output "+" utmost point, and coil J upper terminal 5 connects controllable silicon anode and probe A respectively, and bridge rectifier output "-" utmost point connects the silicon controlled negative electrode, and the silicon controlled control utmost point is connected with probe B; An end links to each other with the silicon controlled negative electrode after capacitor C and the resistor R parallel connection, the other end is connected with the silicon controlled control utmost point; Test switch S is connected in parallel between terminal 5 and the terminal 9.
Beneficial effect: simple in structure, performance safety and stability, cheap, solution rural area water tower draws water and the problem that spilling water is just turned off the suction pump power supply in a great rush often occurs, and the water of realization water tower is taken out to expire and is just cut off the electricity supply automatically, reaches the purpose of saves energy and water resource.
Description of drawings
Accompanying drawing 1 is water tower that the utility model the provides automatic switching circuit catenation principle figure that draws water.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of water tower automatic switch that draws water, its probe " A " and probe " B " can be realized non-maintaining, the long service life advantage, for protection against the tide, behind tin on the twisted pair end scalp, obturage with PUR and to cut off again, make section expose scolding tin and get final product, will pop one's head in the wire of the tape insulation that certain intensity is arranged again and fix in position.When drawing water, the water pump M that draws water behind the combined floodgate begins to draw water, water raises gradually in the dried tower of water, when two probes touched water, electric current triggered the trigger electrode of controllable silicon T through the negative pole end output of bridge rectifier pipe D3 and D4 through coil J, probe A, water, the probe B of electrical apparatus release, one-way SCR T anode and negative electrode conducting, the coil J of electrical apparatus release has electric current by producing magnetic, and the contact J-K auto-action of electrical apparatus release cuts off main circuit, and suction pump M outage stops pumping.Suction pump outage test switch S is connected in parallel between terminal 5 and the terminal 9, and the outage when test electrical apparatus release outage effect and prevention and control circuit break down is standby.When probe was provided with in place, water tower water then can not overflow.
In the accompanying drawing 1, D1-D4 adopts IN4007 model diode: T1 adopts 220/12V12W model transformer; T adopts BT169D model controllable silicon; R adopts the carbon film resistor of 10K Ω; C adopts the monolithic capacitor of 0.1uF.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
