Abstract
The utility model discloses a water level and temperature display apparatus for a solar energy water heater. The utility model has the technical structure that a float made of a permanent magnet ring is sheathed on a sealed copper pipe, and the inner of the sealed copper pipe is provided with a dry reed pipe string and a resistor string. After the water level and the water temperature are sampled, the signals are transmitted to an amplifying display alarm circuit. The utility model has the advantages of simple structure, reliable use and scientific and reasonable scheme. The utility model can be extensively applied to solar energy water heaters.
Description
The utility model relates to the Automatic Measurement Technique field, specifically adopts electronic technology to detect the water level and the water temperature of institute's water storage in the solar water heater.
Normal domestic use solar water heater of the prior art, do not possess the water level of demonstration and water temperature function, grasp all situations of bad water temperature when often causing water heater water spill-over water outlet to irritate roof and use, cause the waste of water resource and can not give full play to solar water heater efficient.
The purpose of this utility model is to adopt electronic technology that a kind of water-level and water-temperature display unit of special use is provided to solar water heater.
For solving above-mentioned task, the solution that the utility model adopts is: the solar water heater water-temperature water-level display unit comprises that mainly Sensor section and water-level and water-temperature signal amplify the display part; The float that Sensor section is done by permanent magnet rings is sleeved on the sealing copper pipe, and the tongue tube string of serial connection and the resistance string of serial connection are installed in sealing in the copper pipe, and their two lead-out wires are connected to and amplify the upper offset resistance of display part as triode amplifier.Veer away big the demonstration and warning circuit after adopting this method sampling water level, water temperature signal.
The water-level and water-temperature display that adopts electronic technology to make in above-mentioned solution has simple in structurely, uses reliably, and scheme is scientific and reasonable, does not change the solar water heater agent structure.So both practical and convenient user.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a sensor construction schematic diagram of the present utility model;
Fig. 2 is a sensor electrical schematic diagram of the present utility model;
Fig. 3 is a water level and water temperature of solar water heater display unit electrical schematic diagram of the present utility model;
In the sensor construction schematic diagram of Fig. 1, permanent magnet rings 1 is sleeved on the sealing copper pipe 2, can be free to slide along sealing copper pipe 2, and the electric part of sensor shown in Figure 2 is installed in sealing in the sealing copper pipe 2.
Fig. 2 provides for further showing the sensor electrical principle, and sensor is that what to utilize that two diode Z 3 of the positive-negative polarity of two on line a and b and sensor internal and Z 4 select to detect at present is water level or water temperature.The equivalent circuit of the sensor of Fig. 2 is the upper offset resistance of the triode amplifier in the display, cause the shutoff of tongue tube string 3 in Fig. 2 during use with fluctuating of water level as the permanent magnet rings 1 of float, thereby the all-in resistance of resistance string 4 is changed, sensing water level and temperature signal.The connecting relation of Fig. 2 sensor is: two on lines two branch roads that connect parallel connection wherein, wherein branch road at first connects the positive pole of diode Z3, the negative pole connecting resistance string 4 of Z3 and the fixed contact of tongue tube string 3, resistance and tongue tube are the spaces, connect then to form.(present embodiment has been adopted and 10 resistance and 9 tongue tubes.) another in parallel branch road at first connects the negative pole of Z4, the positive pole of Z4 connects a thermistor; Another root of two on lines connects the movable contact of tongue tube string 3.
Fig. 3 is the electrical schematic diagram of display, and it utilizes publicly-owned amplifier technology, amplifies and utilizes ammeter to show water level and water temperature signal.Two on lines that sensor is drawn are introduced the corresponding input of amplifier by double-point double-throw switch 5, as the upper offset resistance of corresponding triode amplifier.Wherein diode Z1, Z2 and resistance R are formed voltage-stabilized power supply, reduce the influence of cell voltage variation to display precision.Potentiometer W1, W3 can adjust the original position that shows water level, water temperature electric current indicator, and potentiometer W2, W4 can adjust the maximum position that shows water level, water temperature electric current indicator.
Certainly, the utility model shows what water level, water temperature circuit did not limit among the embodiment to be exemplified, and the various conversion that the above-mentioned principle of all foundations is done all should drop within the protection domain of the present utility model.
