Description

The water level display controller

The utility model relates to a kind of water level display control unit, particularly retaining tower, cistern, the used water level display control unit of water storage box.

The water of office building, residential building is all by water tower, water tank or underground conservation pool supply at present, the water level situation of water tower shows by buoy usually, easy-to-rust after its use a period of time, mechanical driving part also easily gets stuck, the water inlet of ball float control is easy to failure, cause and do not intake or the spilling water phenomenon, and breakdown maintenance is also very inconvenient.The water level of water tank or underground conservation pool then by manual observation, can not show intuitively that human factor is too big, and the phenomenon of cutting off the water that causes because of work mistake can take place.And, if the water in the water tank, underground conservation pool uses up, be not staff's error, owing to do not have water level to show then to occur often the user to the doorstep or the phone reflection, blame the irresponsible misunderstanding situation of water supply personnel for, make troubles to work, also cost dispute and constantly explain.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of water tower, water tank, pond all suitable, can closely also can control the water level display controller of water inlet automatically with the remote water level situation that shows synchronously.

Technical solution of the present utility model:

A kind of water level display controller, it is by sensor, display and control circuit are formed, sensor is made of body (1) and conductor sensor contact (2), indicate the scale (3) of the different water levels of expression on body (1) outer wall from top to bottom, corresponding each scale (3) is equipped with conductor sensor contact (2) on body (1) tube wall, and the lead (11) of each sensor contact (2) by separately is connected to control circuit separately, the output of each control circuit meets luminous indicating diode FD separately, and each is indicated diode FD correspondence to be arranged on the lip-deep equivalent water level scale of display (4) (5) and locates.

The utility model is simple in structure, and dependable performance shows water level automatically, and control electromagnetic valve guarantees inflow automatically simultaneously, greatly reduces labour intensity, and maintenance and use are all very convenient.The utility model applicability is strong, no matter be water tower, on the ground water storage box still is that underground conservation pool etc. all can use, can demonstrate their water situation automatically, not only retaining place has demonstration, also be communicated to user's concentration zones or be responsible for water supply department remote demonstration is synchronously also arranged, can reduce human factor on the one hand, reduce owing to misread the work contradiction that causes, make people's a glance just understand the water situation of retaining place, needn't blame that the staff has also reduced many disputes with shooting at random again simply for, provide advantage for scientific management on the other hand.

Fig. 2 is a hollow tubular body sensor structural representation of the present utility model;

Fig. 3 is each control circuit electrical schematic diagram of the present utility model.

As Fig. 1-3, the body of sensor of the present utility model (1) can be a sealed tube body, seal its underpart, top is decurved opening, its length is greater than the maximum water storage height in water tower or water storage box pond, it is packed on the inwall in water tower water storage box pond, its lower end contacts with at the bottom of the tower or bottom surface, water tank pond, its upper end exceeds the highest water surface, to guarantee not having water all the time in the sealed tube body (1), each metallic conductor sensor contact (2) that is provided with in scale (3) place of each water level of representative of body (1) all insulation plug (6) by separately is connected as a single entity with the corresponding tube wall of body (1) place, body (1) is all exposed so that contact with water in water tower or the water storage box pond in their outer end, their the inner all be positioned at body (1) and the lead (11) by separately from the upper end decurved opening draw the control circuit that connects separately.The body of sensor (1) also can be hollow straight tube, its lower end is connected with water tower or bottom, water storage box pond, ground sidewall by elbow, its length should be greater than the peak level in water tower or water storage box pond, ground, make the interior water level of body (1) always consistent with the water level in water tower or the water storage box pond, ground, each metallic conductor sensor contact (2) of locating to be provided with on the outer wall at its each level scale (3) also all is connected as a single entity by insulation plug (6) and body (1), their end all stretches into and contact with water in the body (1), and their other end is positioned at the outer lead (11) that also passes through separately of body (1) and is connected with separately control circuit.The sensor of sealed tube body all is suitable for various water storage containers, and the sensor of hollow body is not suitable for underground conservation pool.Each control circuit of the present utility model all can be the voltage comparator circuit of being made up of amplifier IC and resistance R, a their input termination reference power supply Vcc, the line of their another input end and each self-corresponding conductor sensor contact (2) joins, their output is connected to luminous indicating diode FD separately, the wiring board of each control circuit (7) all is arranged in the display (4), each luminous indicating diode FD is arranged on the corresponding water level display scale (5) in display (4) surface according to the height of water level of representative and locates, in the control circuit of lowest water level and peak level, their output is respectively by transistor amplifier circuit BG and relay J 1, J2 connects, J1, the normally-open normally-close contact of J2 is connected with entering water electromagnetic valve, finishes automatic water inlet or stops into water.Display of the present utility model (4) also can be connected with remote synchronization indicator (8), its surface also indicates the indicating graduation (9) of expression height of water level, each scale (9) locates to be equipped with each self-corresponding remote luminous indicating diode (10), can be connected to separately relay at the output terminal of each water-level control circuit, the contact of each relay connects with the remote luminous indicating diode (10) of corresponding each height of water level of representative, to connect independent current source in the remote display unit (8) to remote luminous indicating diode (10) power supply of each correspondence.

During the utility model work, if the water in water tower or the water storage box pond is filled, then the conductor sensor contact (2) of each sensor all contacts with water, just produce an electronegative potential, make the amplifier IC work of each control circuit, IC has signal output, and then each luminous indicating diode FD is bright, simultaneously can make each remote luminous indicating diode (10) also bright, then on display (4) and remote synchronization indicator (8), all reflect the retaining situation of full-water level by each self-corresponding relay.When the water in water tower or the water storage box pond is used by the user and makes decline of water table, the sensor conductor sensor contact (2) that then is positioned at above water level this moment does not contact water, amplifier IC in the then corresponding control circuit is input as noble potential, so this amplifier IC does not work, corresponding luminous indicating diode FD and remote luminous indicating diode (10) go out, then on display (4) and remote display unit (8), can find out water level situation at that time intuitively, when water is reduced to lowest water level, all luminous indicating diode FD and remote luminous indicating diode (10) all go out, this moment, the utility model was intake in water tower or water storage box pond by relay J 1 control entering water electromagnetic valve, finished the work of automatic water supplement.
