Description

Technical Field

[0001] The utility model belongs to the technical field of solar water heaters, and in particular relates to a solar thermal storage water heater. Background Art

[0002] A solar water heater is a heating device that converts sunlight energy into thermal energy. A vacuum tube household solar water heater is composed of a heat collecting tube, a water storage tank, a bracket and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum collecting tubes. Vacuum collecting tubes use the principle that hot water floats and cold water sinks to create microcirculation of water and obtain the required hot water.

[0003] The existing solar water heaters on the market are prone to scale accumulation inside the water tank after long-term use. Since the water tank has a large capacity, the accumulated scale is also more, and too much scale will not only affect the water quality but also the health of the users. Therefore, the scale is usually handled by manual cleaning on the market, which makes cleaning very difficult. In the cleaning process, the heat collecting tubes need to be removed one by one, which is relatively troublesome, time-consuming and labor-intensive. At the same time, the heat collecting tubes are easily damaged in the process, thereby affecting the use of the device.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0006] A solar thermal storage water heater comprises a base and a water tank, wherein a scale cleaning component for scraping scale is arranged in the water tank, a fixing structure for disassembly is arranged on the water tank, the scale cleaning component comprises a threaded rod and a scraper, the fixing structure comprises a fixed seat, a movable seat, a fixed plate and a connecting pipe, the threaded rod is rotatably connected to the water tank, the scraper is threadedly connected to the threaded rod and is slidably connected to the water tank, the fixed seat is movably connected to the base, the movable seat is clamped in the connecting pipe, the fixed plate is rotatably connected to the water tank, and the movable seat is limited by the fixed plate.

[0007] As a preferred embodiment of the utility model, a water tank is fixedly placed above the base, and the fixing seat is fixed in the base by bolts.

[0008] As a preferred embodiment of the utility model, a fixing ring is fixedly connected to a plane on one side of the water tank, a fixing column is fixedly connected to a plane on the other side of the water tank, the fixing ring and the fixing column are symmetrically arranged on the two end planes of the water tank, the fixing ring and the fixing column are both threadedly connected with different plug covers, and different fixing plates are rotatably connected on the curved surfaces of the fixing ring and the fixing column, two of the fixing plates are located on both sides of the movable seat, the two fixing plates are fixed to the movable seat by bolts, a heat collecting tube is clamped in the movable seat, one end of the heat collecting tube is clamped in the through hole of the movable seat, the other end of the heat collecting tube is clamped to the fixed seat, a sealed bearing is arranged in the fixing ring, and the fixing ring is rotatably connected to the other end of the threaded rod through the sealed bearing.

[0009] As a preferred embodiment of the utility model, a plurality of circular holes are opened in a curved surface on one side of the water tank, a plurality of connecting pipes are fixedly connected in the circular holes, a plurality of through holes are opened in the movable seat, annular grooves are opened in the through holes, the size of the annular grooves is similar to that of the connecting pipes, and the movable seat is clamped with the connecting pipes through the annular grooves.

[0010] As a preferred embodiment of the utility model, a slide groove is opened inside the water tank, a slider is fixedly connected to the curved surface of the scraper, the slider slides in the slide groove, a threaded hole is opened at the center of the scraper, and the scraper is threadedly connected to the threaded rod through the threaded hole.

[0011] As a preferred embodiment of the utility model, a rotation groove is opened on the inner wall surface of the water tank, and an adaptive bearing is arranged in the rotation groove. The water tank is rotatably connected to one end of the threaded rod through the bearing, and the other end of the threaded rod is fixedly connected to a handle.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Turn the handle to rotate the threaded rod, thereby mobilizing the scraper to move. The scraper's slider will slide in the slide groove of the water tank. At the same time, the scraper will scrape the inner wall of the water tank, causing the scale to fall off and eventually be discharged from the connecting pipe. The scale removal component is used instead of manual cleaning, which ensures the water quality in the water tank while ensuring the health of residents' water use.

[0014] 2. By setting up a fixed structure, when the water tank needs to be cleaned, the fixed seat is removed, and then the fixed plates on both sides of the movable seat are loosened. All the heat collecting tubes can be removed by pulling the movable seat, which avoids the difficulty of removing the heat collecting tubes one by one. It saves time and effort relatively speaking, and also avoids damage during removal to a certain extent, protects the heat collecting tubes, and ensures the use of the device.

When in use, the movable seat 13 and the water tank 14 need to be installed first, and then the heat collecting tube 12 is inserted into the movable seat 13, and finally the fixed seat 11 is inserted into the bottom of the heat collecting tube 12, and then the fixed seat 11 and the base 10 are connected.

[0026] like Figure 3 and Figure 5 As shown, a fixing ring 15 is fixedly connected to a plane on one side of the water tank 14, and a fixing column 18 is fixedly connected to a plane on the other side of the water tank 14. The fixing ring 15 and the fixing column 18 are symmetrically arranged on the two end planes of the water tank 14, and the fixing ring 15 and the fixing column 18 are both threadedly connected with different plug covers 22.

[0027] The working principle is as follows: the diameter of the outer ring of the fixing ring 15 is consistent with the diameter of the fixing column 18, the length of the fixing ring 15 is consistent with the length of the fixing column 18, the inner ring of the fixing ring 15 is provided with a thread, the interior of the fixing column 18 is provided with a threaded hole, the fixing ring 15 is threadedly connected to the plug cover 22 through the inner thread, the fixing column 18 is threadedly connected to another plug cover 22 through the threaded hole, and a circle of high-temperature resistant sealing ring is provided on the plug cover 22.

Different fixing plates 16 are rotatably connected on the curved surfaces of the fixing ring 15 and the fixing column 18 respectively. The two fixing plates 16 are located on both sides of the movable seat 13. The two fixing plates 16 fix the movable seat 13 by bolts. A heat collecting tube 12 is clamped in the movable seat 13, and one end of the heat collecting tube 12 is clamped in the through hole of the movable seat 13, and the other end of the heat collecting tube 12 is clamped with the fixed seat 11.
