[0001] The present invention relates to the technical field of solar heat preservation tubes, and more specifically, to a solar heat preservation tube that is convenient to clean. Background Art

[0002] A solar water heater is a heating device that converts solar energy into heat energy, heating water from a low temperature to a high temperature to meet the hot water usage of people in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, with vacuum tube solar water heaters being the main type, occupying 95% of the domestic market share. A vacuum tube household solar water heater is composed of a heat collecting tube, a water storage tank, brackets and other related parts. The conversion of solar energy into heat mainly relies on the vacuum heat collecting tube. The vacuum heat collecting tube utilizes the principle that hot water floats and cold water sinks to cause water to have a microcirculation to obtain the required hot water.

[0003] In the prior art, a solar water heater for conveniently cleaning a heat collecting tube with the publication number of CN113669930B, the water tank is connected to the mounting frame, several heat collecting tubes are connected to the water tank, two driving components are connected to the mounting frame, two outer cylinders are connected to the two driving components, two shock absorption springs are connected to the two outer cylinders, two inner cylinders are connected to the two shock absorption springs, a cleaning frame is connected to the two inner cylinders, several cleaning brushes are connected to the cleaning frame, a connecting pipe is connected to the water tank, a conveying component is connected to the connecting pipe, a winding component is connected to the water tank, the heat collecting tube is fixed on the mounting frame, the conveying component transports the water in the water tank to the cleaning brush through the connecting pipe, the driving component drives the cleaning frame to drive the cleaning brush to move to clean the heat collecting tube, and the shock absorption spring absorbs the vibration generated when the cleaning frame works, solving the problem of poor stability at the connection end between the heat collecting tube and the mounting frame of the solar water heater for conveniently cleaning the heat collecting tube.

[0004] In the prior art, a solar water heater for conveniently cleaning a heat collecting tube with the publication number of CN110486953B, which relates to the technical field of solar water heaters. The invention includes a base, one end face of a slider is fixedly connected to the circumferential side of a nut, the other end face of the slider is fixedly connected with a hanging ring, the circumferential side of the water storage tank is rotatably connected to the inner wall of the hanging ring through a bearing, a cleaning groove is formed on the upper surface of the base, a tail support plate is hinged between the side faces of a sliding seat through a hinge seat, one end face of the heat collecting tube is fixedly connected to the surface of the tail support plate, a cleaning plate is threadedly connected to the circumferential side of a second lead screw, and an upper brush is fixed on the top of the cleaning plate. Through the design of a driving device, a hanging ring, a cleaning groove, a sliding seat, a tail support plate and a cleaning plate, the present invention can automatically clean the dust and dirt on the circumferential side of the heat collecting tube, has a simple structure and a high degree of automation, and avoids the problem that the circumferential side of the heat collecting tube of the existing solar water heater is prone to accumulate dust and dirt, is inconvenient to clean, and results in a reduction in the conversion rate of solar energy.

[0005] However, when existing solar water heaters are in use, although the heat preservation pipes can be disassembled and cleaned well, when it is necessary to clean the water scale in the water storage tank of the solar water heater, the water scale is often cleaned through a cleaning rod from the water outlet. The effect of directly installing a scraper into the water storage tank to automatically rotate and scrape the inner wall water scale is not high, and when the water scale falls from the water outlet, the effect of simultaneously dredging the accumulated water scale at the water outlet is not high. It is easy to cause blockage of the water scale at the water outlet due to a large amount of water scale, which requires manual cleaning by staff, increasing the workload of the staff and reducing the automatic cleaning efficiency of the solar water heater, not meeting the usage requirements of people. Therefore, we propose a solar heat preservation pipe that is convenient for cleaning. Summary of the Invention

[0049] Next, when the scale in the water storage tank 2 is automatically scraped and cleaned by the scraping plate 17, in order to improve the synchronous dredging effect of the installation port between the water storage tank 2 and the heat preservation pipe, when the connecting shaft 11 rotates, it drives the first gear 20 and the second gear 23 to rotate. The rotation of the second gear 23 drives the connecting column 26 and the spring 25 to move reciprocally telescopically through the reciprocating extrusion movement of the clamping rod 27, and drives the connecting column 26 to move reciprocally telescopically, playing a role in automatically synchronously dredging the scale accumulated at the water outlet, so as to improve the efficiency of scale cleaning;

[0050] Finally, when it is necessary to clean the dust adsorbed on the outer wall of the heat preservation pipe body 3 to improve the absorption effect of the heat preservation pipe on solar energy, the second servo motor 28 is turned on. Through the rotation of the first threaded rod 29, the reciprocating slider 30 is driven to slide along the outer wall of the bracket main body 1, and the third servo motor 31 is turned on. Through the rotation of the second threaded rod 32, the cleaning block 33 is driven to slide along the inner wall of the chute 34, so that the cleaning block 33 fits on both sides of the heat preservation pipe body 3, playing a role in conveniently cleaning the dust adsorbed on the outer wall of the heat preservation pipe.
