Technical Field

[0001] The utility model relates to the field of solar water heaters, in particular to a solar hot water remote monitoring device. Background Art

[0002] In the case of the decreasing of fossil fuels, solar energy has become an important part of the energy used by humans and is constantly developing. There are two ways to utilize solar energy: photothermal conversion and photoelectric conversion. Solar power generation is a new type of renewable energy.

[0003] Currently, the solar hot water systems in each camp in the Wudongde Dam area mainly rely on manual inspections for daily checks. During daily operation and maintenance, a maintenance worker needs to be assigned every day, investing about 6 hours. This often requires the maintenance worker to sacrifice rest time to conduct a comprehensive inspection of the solar systems on all rooftops under the jurisdiction of the branch company to ensure the normal operation status of the equipment. Even so, we still cannot understand the hot water temperature of the solar hot water system in real time and accurately monitor the hot water changes, making it impossible to immediately master the hot water supply situation. Secondly, under harsh weather conditions such as thunderstorms, manual inspections become extremely difficult, not only with low inspection efficiency but also posing potential safety hazards to the inspection personnel.

[0004] Therefore, we urgently need to seek a more efficient and intelligent monitoring solution for the solar hot water temperature system to improve the operation efficiency and service quality. Summary of the Utility Model

[0008] In a preferred solution, a pull ring is further provided above the protective shell, and a lifting device is provided above the pull ring. The lifting device is used to lift the position of the detection point of the temperature sensor probe, so as to detect the temperature at different depths in the water tank.

[0009] In a preferred embodiment, the lifting device includes a housing, a bottom plate installed below the housing, a lifting assembly installed on the bottom plate. The lifting assembly includes a support, a winding drum installed on the support, a motor installed at one end of the winding drum, a thin rope installed on the winding drum, and one end of the thin rope is connected to a pull ring.

[0010] In a preferred embodiment, a liquid level sensor is further provided in the water tank, and electric valves are provided on the water inlet pipe and the water outlet pipe of the solar water heater tank.

[0012] The beneficial effect of the present utility model is that since the present utility model provides a solar hot water remote monitoring device, by setting a temperature control probe in the solar water tank and setting a PLC controller and a wifi wireless router outside, the PLC controller can send the temperature value in the water tank detected by the temperature control probe to the mobile phone, thereby realizing the monitoring of the temperature in the water tank.

Detailed Embodiment

[0018] Please refer to Figures 1-3 As shown, the embodiment of the present application provides a technical solution: a solar hot water remote monitoring device, including a temperature sensing probe 2 provided in the solar water heater tank 1, a PLC controller electrically connected to the temperature sensing probe 2, a wireless communication module provided on the PLC controller, a wifi wireless router network-connected to the PLC controller, and a smart phone for receiving the temperature information sent by the wifi wireless router.

[0019] When the temperature sensor probe 2 detects the temperature in the water tank 1, it transmits the temperature signal to the PLC. The PLC sends information through a wifi router, and then the worker can obtain the temperature value from the APP software on the mobile phone. The APP software can be the ShouXin IOT APP.

[0020] The PLC controller and the wifi router can be set in the electric control box.

[0021] In a preferred solution, a protective shell 3 is provided outside the temperature sensor probe 2. The temperature sensor probe is inserted into the protective shell 3. A through groove 31 is provided on the outside of the protective shell, and a filter screen 32 is provided on the through groove 31.

[0022] The model of the temperature sensor probe 2 can be the waterproof DS18b20, or it can be other temperature detection devices, such as a temperature sensor.

[0023] The main function of setting the housing and the filter screen 32 is to prevent impurities in the water tank 1 from adsorbing onto the temperature probe 2, thereby affecting the detected temperature.

[0024] In a preferred solution, a pull ring 33 is further provided above the protective shell 3, and a lifting device 4 is provided above the pull ring 33. The lifting device 4 is used to lift the position of the detection point of the temperature sensor probe 2, so as to detect the temperature at different depths in the water tank 1. The lifting device 4 can be set above the water tank 1.

[0025] The purpose of detecting the water temperature at different depths is that since the heat transfer of solar energy has a process, if the temperature at the outlet of the outlet pipe has been appropriate, a part of the hot water near the outlet pipe can be given priority to be discharged when urgently needed, without waiting for the water temperature in the water tank 1 to reach the specified temperature.

[0026] In a preferred solution, the lifting device 4 includes a housing 41, a bottom plate 42 installed below the housing 41, a lifting assembly 5 installed on the bottom plate 42. The lifting assembly 5 includes a support 51, a winding drum 52 installed on the support 51, a motor 53 installed at one end of the winding drum 52, a thin rope 54 installed on the winding drum 52, and one end of the thin rope 54 is connected to the pull ring 33.

[0027] In this way, the motor 53 drives the winding drum 52 to rotate, and the protective shell 3 connected by the thin rope 54 can drive the temperature control probe 2 to rise and fall.

[0028] In a preferred solution, a liquid level sensor is further provided in the water tank 1, and electric valves 11 are provided on the inlet pipe and the outlet pipe of the solar water heater water tank.

[0029] In a preferred solution, an electric heating wire is also installed on the side wall of the water tank 1.

[0030] Another purpose of setting up the electric heating wire is that in case of weak sunlight or rainy and cloudy weather, such as in the severe winter when the solar radiation energy is low and the water temperature in the water heater is too low to reach the required temperature, it is difficult to meet the user's demand for hot water. Therefore, an electric heating wire is installed in the water tank 1. The electric heating wire is electrically connected to the PLC controller. The heating resistance wire is installed on the side wall of the water tank 1 and starts to work when the solar illumination cannot meet the heating requirement. The mobile phone controls the electric heating wire to heat the water body according to the temperature feedback from the temperature sensor in the water tank 1, so as to avoid the shortage of hot water supply.

[0031] When the water tank needs to be maintained at a certain temperature, if the temperature of the water tank 1 is too low, the electric heating wire can be controlled to heat the water tank. When the temperature of the water tank 1 is too high, the electric valve 11 on the outlet pipe is controlled to open to drain a part of the hot water, and then the solenoid valve on the inlet pipe is opened to add a part of cold water, or the solenoid valve on the inlet pipe is directly opened to add cold water, which is determined according to the water capacity in the water tank 1.

[0032] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations to the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
