CN2072698U - Full-automatic water tank, body of water interlock control device - Google Patents

Abstract

The utility model discloses a device which uses the buoyant force of liquid to control positions of upper and lower limits of water levels of water tanks and ponds in interlocking. When a magnet arranged in a floating ring moves up and down following the water levels, the automatic regulating purpose of attracting or separating a dry spring tube arranged in a tube is obtained. Both ends of the tube are provided with limiting devices. Thus, the device overcomes the defect that a water pump is frequently started because inflow water quantity is too little in the pond. The device uses a few components, and actions are reliable.

Description

Full-automatic water tank, body of water interlock control device

The utility model relates to the interlocked control of water tank and the upper and lower water level of storage cistern.

The form of present existing water level automatic control device has many kinds, but does not all relate to the control problem of the water pump frequent starting that produces when storage cistern is less than aquifer yield because of inflow.

The purpose of this utility model be design a kind of simple in structure, with low cost, automaticity is high, good reliability, full-automatic water tank, storage cistern interlock control apparatus easy to maintenance.Water pump that aquifer yield causes is found time or the problem of frequent starting because of the few water of storage cistern or inflow are less than in order to solve.

This device adopts machinery to realize its purpose with the mode that electricity cooperates, only adopt a power transformer, two water level controllers, one relay of merely hitting, a contactor is formed, water level controller is that the floating ring by the band magnetite moves with water level and adhesive or separate tongue tube is switched on or switched off control circuit, and then the starting or stoping of control water pump.

The electrical schematic diagram of this device as shown in Figure 1.

The structure of its water level controller as shown in Figure 2.

On among the figure 5, be for 5 times the tongue tube in the water level controller of water tank, on 6, be for 6 times the interior tongue tube of water level controller of storage cistern, be closed type on 5,5 times is open type, is open type on 6,6 times is closed type.Tongue tube is contained in the pipe 1, the floating ring 2 that has permanent magnet 3 is enclosed within that the variation with water level moves up and down on the pipe 1, adhesive or separation are contained in the tongue tube in the pipe, at the upper and lower side of pipe 1 a locating device 7,8 in order to floating ring is limited in upper and lower definite position is arranged, the locating device position should be decided with the position of tongue tube in the pipe, and its effect is not only for preventing because of having a power failure or other reasons makes control circuit effect out of hand after causing water level to surpass the Be Controlled water level.And after the water level of storage cistern surpasses floating ring locating device 7, floating ring has rested on the adhesive of locating piece place tongue tube, no matter this moment, how high water level had, water pump is controlled by upper water box.When the storage cistern water level is pumped down to down locating device 8 places, circuit disconnects, if the inflow of storage cistern more at this moment, water level rises gradually, but because of last gauge tap disconnects, water pump can not start, when level control switch for water is gone up in arrival, water pump just starts, repeat above-mentioned action, thereby has avoided the problem of the frequent starting that water pump causes when the upper and lower fluctuation in place, water level control position down because of the storage cistern water level.The close together of locating device up and down of the water level controller of storage cistern can be obtained by the shortest requirement interval time of starting of pump station.The voltage of this control circuit adopts the following safe voltage of 36V, in case the harm that an electric leakage causes to human body, the utility model also can separate independent use, to reach the purpose of independent control.Floating ring 2 internal cavities can be filled with polyfoam or other light material filling that can float over above the liquid with independent pore than liquid light.

Claims (5)

1, a kind of device that utilizes liquid buoyancy that the upper and lower limit water level in water tank, pond is interlocked and controlled automatically, it is characterized in that water tank, water level in water pool controller by the band locating device, the full-automatic liquid level interlocked control circuit that device and A.C. contactor are formed continues in the centre.

2,, it is characterized in that the move up and down locating device of position of restricted floating ring on the water level controller by the described interlocking automaton of claim 1.

3, by claim 1 or 2 described interlocking automatons, it is characterized in that the position location of the switch up and down close together of storage cistern water level controller, after water level surpassed upper limit position, floating ring still rested on upper limit position, the tongue tube in the adhesive controller.

4, by claim 1,2 or 3 described interlocking automatons, the last bit switch that it is characterized in that tank water level controller is a normally closed contact, and following bit switch is a normally opened contact; The last bit switch of water level in water pool controller then is a normally opened contact, and following bit switch is a normally closed contact.

5,, it is characterized in that the floating ring internal cavity is used than the polyfoam of liquid light or other to fill and fill with the light material above the liquid of floating over of independent pore by claim 1,2 or 3 described interlocking automatons.
