[0002] Solar energy is a renewable energy source, which refers to the heat radiation energy of the sun. See the three ways of heat energy transmission: radiation, which is mainly manifested in the commonly known sunlight, is generally used to generate electricity or provide energy for water heaters in modern times. Since the birth of life on Earth, it has mainly survived on the heat radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. With the decreasing fossil fuels, solar energy has become an important part of human energy use and is constantly developing;

[0003] In the solar energy industry, solar water heaters are the most widely used products in this industry. Most households have solar water heaters installed. Solar water heaters are equipped with solar tubes. The solar tubes are set outdoors. Long-term use will accumulate some dust attached to the solar tubes, affecting the heat absorption efficiency of the solar tubes. The current ways to clean solar tubes include rainwater cleaning, that is, directly using rainfall to clean in rainy areas, and manual cleaning. In areas and seasons with little rain, they need to be cleaned regularly, which is more cumbersome.

[0004] In view of this, the utility model provides a solar tube cleaning and dust removal device to solve the above problems. Utility Model Content

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0025] The utility model provides a solar tube 2 cleaning and dust removal device, comprising a water tank 1 and a solar tube 2, wherein the water tank 1 is connected with a water inlet pipe 3 and a water outlet pipe 4, and further comprises a temperature difference monitoring unit 6 and a cleaning unit 5, wherein the temperature difference monitoring unit 6 is arranged in each solar tube 2 and the water tank 1, and the cleaning unit 5 is arranged at the lower end of each temperature difference monitoring unit 6 along the direction of the solar tube 2.

[0026] When cleaning the solar tube 2, the cleaning unit 5 can release the water in the water tank 1. Since the solar tube 2 is placed at an angle, the water in the cleaning unit 5 will flow downward along the outer wall of the solar tube 2 due to the drainage effect after being released, thereby cleaning the dust on the outer wall of the solar tube 2.

[0027] The temperature difference monitoring unit 6 includes an external temperature control sensor 7, an internal temperature control sensor 8 and a processing center 9. The external temperature control sensor 7 is arranged on the outer surface of the solar tube 2, and the temperature sensing end is close to the solar tube 2. The internal temperature control sensor 8 is arranged in the water tank 1 for detecting the inside of the water tank 1. The external temperature control sensor 7 and the internal temperature control sensor 8 are electrically connected to the processing center 9 respectively.

[0028] During operation, the temperature control sensor 7 outside the tube is used to detect the temperature outside the solar tube 2, and the temperature control sensor 8 inside the box is used to detect the water temperature in the water tank 1, and transmits the temperature data outside the solar tube 2 and the water temperature data inside the water tank 1 to the processing center 9 for calculation. The processing center 9 is preferably a micro central processing unit, which compares the temperature data outside the solar tube 2 and the water temperature data inside the water tank 1, and judges whether there is a hidden danger of tube explosion after water is released based on the comparison data and the material of the solar tube 2. For example, the solar tube 2 made of high borosilicate glass can withstand a temperature difference of up to 200°C. If the water temperature outside the solar tube 2 differs from that of the water tank 1 by more than 200°C, there is a risk of tube explosion when the cleaning unit 5 releases water.

[0029] The cleaning unit 5 includes a plurality of spray heads 10 and a spray pipe 11 surrounding each solar tube 2. The plurality of spray heads 10 on a solar tube 2 are connected to the inside and connected to the spray pipe 11. One end of the spray pipe 11 is connected to the water inlet pipe 3, and the other end is connected to the water tank 1. A water mixing valve 12 is provided at the connection between the spray pipe 11 and the spray head 10, and the water mixing valve 12 is electrically connected to the temperature difference monitoring unit 6.

[0030] The mixing valve 12 is used to lower the water temperature in the water tank 1 for cleaning when the outside weather is cold. Since there is little rain and the direct sunlight angle is large in winter in my country, the heat collected by the solar tube 2 is very limited. Therefore, it is necessary to frequently clean the dust on the solar tube 2 to maximize the heat collection efficiency of the solar tube 2. This setting can reduce the water temperature of the cleaning unit 5 during the water discharge process in cold winter weather, thereby reducing the risk of pipe explosion.

[0031] The temperature difference monitoring unit 6 further includes a solar panel 13 , which is electrically connected to the processing center 9 . The solar panel 13 is used to supply energy to the processing center 9 .

[0032] The spray pipe 11 uses a pressure-regulating spray pipe 11 capable of adjusting the spray water pressure. When the attached dust is too stubborn, the water pressure is increased to increase the cleaning efficiency.

[0033] When installing the device, the maximum temperature difference between the outside of the solar tube 2 and the water temperature is set according to the material of the solar tube 2, the data is input to the processing center 9, and the interval for regular cleaning is set. The timing function is turned on after use. When the time for regular cleaning of the solar tube 2 is reached, the processing center 9 will compare the temperature data of the outside of the solar tube 2 and the water temperature data in the water tank 1 to determine whether it is necessary to drain the water. If the temperature outside the solar tube 2 is too high, draining the water is prohibited. When the outside temperature drops (for example, after the sun sets), the temperature difference reaches the draining standard, and then a draining signal is sent to the spray pipe 11. If the temperature outside the solar tube 2 is too low, the water temperature of the discharged water will be lowered in cooperation with the mixing valve 12 to meet the draining standard. The processing center 9 can also be set with a remote control function, and the user can set parameters on the mobile phone and remotely and manually open the spray port for cleaning.
