Abstract
The utility model discloses a water-temperature water-level sensor of a solar water heater, which comprises a water temperature sensor 6, water-level sensor electrodes 8, 9, 10 and 11 and a water-temperature water-level signal processing module 1, and also comprises a wire connecting terminal 2, a silicone fixed piece 3, a stainless steel pipe 4, an insulation silicone rubber 5 and a silicone ring 7, wherein the area of the water-level sensor electrodes 8, 9, 10 and 11 are enlarged, the upper end of the electrode is provided with the wire connecting terminals 13, 14, 15, 16 and 17 to be connected with a signal wire, and each connection point and a processing circuit are arranged inside the silicone ring 7. With the above design, the signal wire and the elements can be prevented from being contacted with the stored water and from being corroded, and the area of the electrode is enlarged, so the water scale formation can be prevented. The water-temperature sensor 6 is arranged inside the stainless steel pipe 12, and the upper end of the water-temperature sensor 6 and the stainless steel pipe 12 are sealed inside the silicone ring 7. Therefore, when detecting the water temperature, the water-temperature sensor is free from being directly contacted with the stored water, so the damage of the elements and the formation of the water scale can be effectively prevented.
Description
Technical field
The utility model relates to a kind of water-temperature water-level checkout gear of solar water heater, is applicable to the solar energy heat utilization field of energy-conserving and environment-protective.
Background technology
Development gradually along with solar thermal utilization, solar water heater is developed rapidly as the main representative of solar thermal utilization, water-temperature water-level sensor can detect water-temperature water-level as a kind of, and detected water-temperature water-level is changed into the components and parts of the signal of telecommunication, in solar water heater, find broad application, equally also play a part very important.Because water-temperature water-level sensor often is operated among the water-heater water tank, in long-term poach and decatize process, holding wire and electronic device are easy to be corroded.The a lot of regional quality problems of China are serious, and incrustation scale is easily attached to sensor electrode and temperature sensing part.So water-fast dirt, the sealing problem of electrode, holding wire and temperature sensing device becomes an insoluble difficult problem always.Water-temperature water-level sensor directly has influence on the water-temperature water-level measure and control device, and the water-temperature water-level sensor working stability is the guarantee to whole solar water heater Based Intelligent Control.
Summary of the invention
The purpose of this utility model aims to provide a kind of incrustation scale that can better prevent and forms the solar water heater water-temperature water-level sensor that holding wire is difficult for being corroded.
To achieve these goals, the solar water heater water-temperature water-level sensor comprises cooling-water temperature sensor 6, level sensor electrode 8,9,10,11, water-temperature water-level signal processing module 1 also comprises binding post 2, silica stationary part 3, stainless steel tube 4, electrically insulating silicone rubber 5 and silica gel circle 7.Be provided with binding post 13,14 in electrode upper end, 15,16,17 are connected with holding wire, and each tie point and treatment circuit place in the silica gel circle 7.Because silica gel circle 7 does not contact the water storage in the water-heater water tank, effectively avoided water storage to infiltrate silica gel circle, the phenomenon that has stoped holding wire and electronic component to be corroded by water storage.Strengthened the area of level sensor electrode 8,9,10,11 simultaneously, effective resistant function has been played in the formation of incrustation scale.
On the other hand, cooling-water temperature sensor 6 is placed in the stainless steel tube 12, cooling-water temperature sensor 6 and stainless steel tube 12 upper ends are sealed in the silica gel circle 7.Because stainless steel tube 12 has good thermal conductivity, do not influence the detection of cooling-water temperature sensor to water temperature, stoped entering of water storage simultaneously, avoid contacting of temperature sensing device and water storage, prevent the formation of incrustation scale and the situation that components and parts are corroded.
Owing to adopt technique scheme, improved the ability of the anti-incrustation scale of solar water heater water-temperature water-level sensor, improved sensor signal lines equally and corroded by water storage, resistance increases even corrosion break signal line, directly causes the malfunctioning phenomenon of control assembly.Improve the reliability of water-temperature water-level sensor greatly, equally also prolonged the service life of sensor.

Fig. 2 is the profile at Figure 1A place, sensor terminals and holding wire connection diagram.
Embodiment
As shown in the figure, the solar water heater water-temperature water-level sensor comprises cooling-water temperature sensor 6, level sensor electrode 8,9,10,11, water-temperature water-level signal processing module 1 also comprises binding post 2, silica stationary part 3, stainless steel tube 4, electrically insulating silicone rubber 5 and silica gel circle 7 are with level sensor electrode 8,9,10,11 area strengthens, be provided with binding post 13,14,15 in the electrode upper end, 16,17 are connected with holding wire, and each tie point and treatment circuit place in the silica gel circle 7.
Cooling-water temperature sensor 6 is placed in the stainless steel tube 12, and cooling-water temperature sensor 6 and stainless steel tube 12 upper ends are sealed in the silica gel circle 7.Because stainless steel has good thermal conductivity, cooling-water temperature sensor not direct contact water source also can be experienced the variations in temperature of water tank.Because the sensor electrode upper end all is sealed in the silica gel circle 7, be positioned at water surface top, certain interception is played in the corrosion that prevents holding wire and components and parts.
