Description

TECHNICAL FIELD

[0001] The utility model relates to radiation air conditioning auxiliary equipment technical field, especially a radiation air conditioning's water tank automatic exhaust and water level, water quality monitoring device. BACKGROUND

[0002] Radiation air conditioning refers to setting up cold or hot pipeline in the enclosure structure, or laying up radiation plate on the inner surface of the enclosure structure, lowering or raising the inner surface temperature of the maintenance structure through water circulation, forming cold and hot radiation surface, and utilizing the cold and hot radiation surface and the human body, furniture and other object surface to exchange heat. The radiation air conditioning system is mainly composed of cold and hot source host equipment, water tank, conveying and distribution equipment, dehumidification fresh air equipment and intelligent control equipment. The main functions of the radiation air conditioning water tank include the following aspects: balancing system pressure, storing energy and adjusting temperature, prolonging equipment life, protecting system equipment, improving system efficiency, etc.

[0003] In practical application, during installation or maintenance, air may enter the system pipeline or equipment, which reduces the efficiency of heat or cold energy transmission, and even may cause system failure. In order to reduce the influence of air, the existing technology is to open the air valve at the upper end of the water tank at regular or irregular intervals, which brings inconvenience to the user. When the air in the system pipeline is relatively large and the user does not discharge the air in time, the stable and reliable operation of the radiation air conditioning system cannot be guaranteed. In addition, due to the influence of various factors (such as leakage points in the pipeline or related equipment), the water in the water tank may be reduced. When the water level is reduced to a safe value and the user does not add water in time, the radiation air conditioning system may work abnormally. Finally, the existing radiation air conditioning system does not have water quality detection function. After a long time of use, the substances falling off from the inner wall of the pipeline or related equipment or impurities in the water may pollute the water and increase the turbidity, which adversely affects the output of heat source or cold source (even causes pipeline blockage).

[0005] The technical solution adopted by the utility model to solve the technical problems is:

[0006] The application discloses a water tank automatic exhaust and water level and water quality monitoring device of a radiation air conditioner, which comprises a battery, a water flow generator, a liquid level switch, a first alarm, a water quality detection mechanism and an exhaust mechanism.

[0010] Further, the light emitting surface of the light emitting diode and the light receiving surface of the phototriode are horizontally in a straight line state.

[0011] Further, the prompt circuit comprises electrically connected resistors, a second alarm, triodes and resistors, and is connected with the light emitting diode and the phototriode through wires, wherein one end of the three resistors is connected with the positive power input end of the second alarm, the other end of the first resistor is connected with the positive electrode of the light emitting diode, the other end of the second resistor is connected with the collector of the phototriode, the emitter of the phototriode is connected with one end of the fourth resistor, the other end of the fourth resistor is connected with the base of the first triode, the other end of the third resistor is connected with the collector of the first triode and the base of the second triode, the collector of the second triode is connected with the negative power input end of the second alarm, and the emitters of the two triodes are connected with the negative electrode of the light emitting diode.

[0018] Figure 1 、 2 As shown in Figure 3, the outer diameter of the limit plate 232 is larger than the outer diameter of the spring 22 (the elastic force just ensures that the lower end of the sealing plate fits the upper end of the cylinder to prevent dust and the like from entering the water tank) and the inner diameter of the guide hole 211. A sealing rubber pad 24 is glued to the lower end of the sealing plate. The float height of the liquid level switch S1 is higher than the height of the drain pipe 106 of the water tank. The light-emitting surface of the light-emitting diode VL and the light-receiving surface of the phototransistor T1 are respectively located outside the inner ends of the two outer shells, and the light-emitting surface of the light-emitting diode VL and the light-receiving surface of the phototransistor T1 are in a straight line horizontally. The prompt circuit includes resistors R1, R2, R3, R4, the second alarm B1, transistors T2 and T3 connected by circuit board wiring, and are connected to the light-emitting diode VL and the phototransistor T1 by wires, wherein one end of the three resistors R1, R2, R4 is connected to the positive power input end of the second alarm B1,

[0019] The other end of the first resistor R1 is connected with the positive pole of the light emitting diode VL, the other end of the second resistor R2 is connected with the collector of the phototriode T1, the emitter of the phototriode T1 is connected with the one end of the fourth resistor R3, the other end of the fourth resistor R3 is connected with the base of the first transistor T2, the other end of the third resistor R4 is connected with the collector of the first transistor T2 and the base of the second transistor T3, the collector of the second transistor T3 is connected with the negative pole power input end of the first alarm B1, the emitters of the two transistors T1 and T2 are connected with the negative pole of the light emitting diode VL. The resistance values of the resistors R1, R2, R3 and R4 are 400Ω, 100Ω, 10K and 200K respectively, the type of the transistor T2 is 9013, the light emitting diode VL is a red light emitting diode, the type of the phototriode T1 is 1N23A, the alarms B and B1 are active continuous sound alarm products of MF12V type, the sounds emitted by the two alarms are different, which is convenient for the user to distinguish whether the water is short or turbid. The water flow generator M is a small volute impeller water flow type generator with output voltage of 6V DC, the storage battery G1 is a lithium storage battery of 6V / 5Ah type, the liquid level switch S1 is a floating ball type normally closed contact liquid level switch, and the transistors T2 and T3 are NPN transistors of 9013 type. The above-mentioned electrical components are all existing mature technologies, and the working principles thereof will not be described herein.

[0020] Figure 1 、 2 , as shown in Fig. 3, the two poles of the storage battery G1 are connected with the two poles of the water flow generator M, the other end of the power input resistor R4 of the prompting circuit and the emitter of the transistor T2 are connected through wires, the positive pole of the storage battery G1 is connected with the power input end of the liquid level switch S1 through a wire, and the power output end of the liquid level switch S1, the negative pole of the storage battery G1 and the power input end of the first alarm B are connected through wires.

[0021] Figure 1 、 2 , as shown in Fig. 3, in the new type, before the water flow output by the related pipeline of the radiant air conditioning system enters the water tank 1 (the water in the water tank 1 is output to the related pipeline of the radiant air conditioning system through the drain pipe 106), the water flow will impact the blades of the water flow generator M to rotate, and then the water flow generator M outputs 6V or so DC power to the storage battery G1, and the storage battery G1 stores the electric energy, so that the power supply of the equipment is ensured. The new type realizes the energy saving purpose through the cooperation of the water flow generator and the storage battery, and reduces the inconvenience caused by wiring. When the air amount in the water tank is small, the gas pressure is lower than the pressure of the spring 22, the lower end of the sealing plate 23 is in sealing contact with the upper end of the cylinder 21, which can prevent the external dust and the like from entering the water tank. When the air amount in the water tank is relatively large, the gas pressure is higher than the pressure of the spring 22, the gas pressure overcomes the pressure of the spring to drive the sealing plate 23 to move upward, and the lower end of the sealing plate 23 is separated from the upper end of the cylinder 21. In this way, the air in the water tank is discharged to the outside through the air outlet hole 212.

[0022] Figure 1 、 2 When the water level in the water tank 2 is higher than the height of the drain pipe 106 of the water tank 2, the two contacts of the liquid level switch S1 will not be closed, so the alarm B will not be powered to sound, which means that the water in the water tank is sufficient. When the water level in the water tank 2 is lower than the height of the drain pipe of the water tank 2, the two contacts of the liquid level switch S1 will be closed, so the alarm B will be powered to sound, which means that the water in the water tank is insufficient, and the staff can add water to the water tank in time (open the sealed cover and add water to the water tank with a water pipe). When the water in the water tank is not turbid, the light emitted by the light-emitting diode VL (the resistor R1 reduces the voltage and limits the current) irradiates the light-receiving surface of the phototriode T2, the phototriode T2 (the resistor R2 reduces the voltage and limits the current) is turned on, the high-level output of the emitter is input into the base of the triode T2 through the resistor R3, the triode T2 is turned on, the low-level output of the collector is input into the base of the triode T3, the base of the triode T3 is not suitable for forward bias and is cut off, and the alarm B2 will not be powered to sound, which means that the turbidity of the water in the water tank is not large. When the water in the water tank is turbid, the light irradiating the light-receiving surface of the phototriode T2 is very small, the phototriode T2 is cut off, the high-level output of the emitter is no longer input, the base of the triode T3 is input with a suitable forward bias through the resistor R4, the triode T3 is turned on, the low-level output of the collector is input into the negative power supply input end of the alarm B1, and the alarm B1 will be powered to sound, which means that the turbidity of the water in the water tank is large. After the user hears the alarm sound, the user can rotate the plug 105, so that the water in the water tank is discharged outward, the water tank is cleaned after adding water through the water tank water adding pipe, then the plug is reinstalled, and the sealed cover is closed after adding sufficient water through the water inlet pipe, so that the whole water changing process is completed. The new type brings convenience to the user, and correspondingly ensures that the radiation air conditioning system can work stably and reliably.
