Description

Technical Field

[0001] This application relates to the field of heating equipment technology, specifically a solar heating box with heat storage function. Background Technology

[0002] Solar energy, as a clean and renewable energy source, is increasingly being used in the heating sector. Existing solar heating boxes with thermal storage functions typically consist of a water storage tank and a collector, with heat transfer achieved through pipeline connections.

[0003] In practical use, this type of solar heating box has some problems. For example, when the vacuum tube collector is in use, its vacuum tubes are exposed to the external environment for a long time, and dust, dirt, and other impurities easily accumulate on their surface. These impurities can block sunlight, reduce the absorption efficiency of solar energy by the vacuum tubes, and thus affect the overall heat collection effect of the heating box. Manual cleaning, on the other hand, presents problems such as inconvenience and safety risks. Therefore, it is necessary to design a solar heating box with heat storage function to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a solar heating box with heat storage function, which solves the problem that dust, dirt and other impurities easily adhere to the surface of the vacuum tube collector in the existing equipment, and these impurities will block sunlight and reduce the absorption efficiency of the vacuum tube for solar energy.

[0006] The technical solution adopted by this application to solve its technical problem is: a solar heating box with heat storage function, comprising: a water storage tank and a heat collector, wherein the water storage tank and the heat collector are connected by a first pipe and a second pipe, and further comprising:

[0007] A linear module is fixed on one side of the solar collector and at the same angle to the vacuum tubes of the solar collector. The linear module has a sliding table with a movable crossbeam that spans multiple vacuum tubes on the solar collector. The linear module is used to drive the movable crossbeam to move up and down.

[0008] The cleaning components are multiple in number and are evenly spaced and installed on the lower end face of the moving crossbeam. The cleaning components are inclined at the same angle as the vacuum tubes in the collector and are correspondingly sleeved on the outer ends of each vacuum tube in the collector for cleaning the outer surface of the vacuum tubes.

[0009] Furthermore, the cleaning component includes a mounting base, the middle of which is fixedly connected to a movable crossbeam by a fixing bolt. Upper connecting sleeves are fixedly connected to both sides of the lower end face of the mounting base. A lower connecting sleeve is detachably connected to the lower end of the upper connecting sleeve. Cleaning brushes are fixedly connected to the inner sides of both the upper and lower connecting sleeves. The two cleaning brushes are combined to form a ring around the vacuum tube and contact the surface of the vacuum tube.

[0010] Furthermore, both the upper and lower connecting sleeves have protruding connecting seats at their outer ends, and the two connecting seats are fixed together by bolts.

[0011] Furthermore, the water storage tank is equipped with a heat exchange tube inside. The heat exchange tube is spiral-shaped, which is suitable for increasing the heat exchange area. The upper end of the heat exchange tube is connected to the second pipeline, and the lower end is connected to the first pipeline.

[0012] Furthermore, a guide rod is fixedly connected to the side of the solar collector away from the linear module, and the tilt angle of the guide rod is the same as the tilt angle of the vacuum tube of the solar collector.

[0013] A connecting frame is fixed to one end of the movable crossbeam away from the linear module, and a guide sleeve is fixed to the lower end of the connecting frame. The guide sleeve is slidably sleeved on the outer end of the guide rod.

[0014] Furthermore, the outer side of the linear module is covered with a protective shell, and the inner side of the protective shell is open, which is suitable for the moving crossbeam to move up and down.

[0015] Furthermore, a circulation pump is installed at the outer end of the first pipeline.

[0016] The beneficial effects of this application are as follows: The solar heating box with heat storage function provided by this application can automatically clean the outer surface of the vacuum tubes of the collector by setting up a linear module and a cleaning component. The cleaning brush in the cleaning component is in contact with the vacuum tube and moves up and down under the drive of the linear module, which can effectively remove dust, dirt and other impurities from the surface of the vacuum tube. There is no need for manual climbing to clean, which improves the convenience and safety of cleaning, ensures that the vacuum tube always maintains good heat collection efficiency, and improves the overall performance of the solar heating box.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-4 As shown, this application provides a solar heating box with heat storage function, including: a water storage tank 1 and a collector 2. The water storage tank 1 and the collector 2 are connected by a first pipe 8 and a second pipe 10. When the solar heating box is working, the collector 2 absorbs solar energy and transfers heat to the internal heat transfer medium. The heat transfer medium flows into the water storage tank 1 through the first pipe 8 to exchange heat with the water in the water storage tank 1, transferring heat to the water in the water storage tank 1 to achieve heat storage. The application also includes:

[0028] Linear module 4 is fixed on one side of collector 2 and is inclined at the same angle as the vacuum tubes of collector 2. The slide of linear module 4 is equipped with a movable crossbeam 5 that spans multiple vacuum tubes on collector 2. Linear module 4 is used to drive the movable crossbeam 5 to move up and down.

[0029] Among them, the linear module 4 adopts a closed linear module to improve service life, and the tilt angle is the same as that of the vacuum tube, which can ensure that the moving crossbeam 5 maintains a stable distance from the vacuum tube when moving up and down, and will not cause the vacuum tube to interfere with the movement of the moving crossbeam 5.

[0030] Cleaning components 6, of which multiple components are evenly spaced and installed on the lower end face of the moving crossbeam 5, are fitted at the same angle as the vacuum tubes in the collector 2 and are correspondingly sleeved onto the outer ends of each vacuum tube in the collector 2 to clean the outer surface of the vacuum tubes. In use, the linear module 4 drives the moving crossbeam 5 to move up and down along the guide rod 7, and the cleaning components 6 on the moving crossbeam 5 move accordingly to clean the outer surface of the vacuum tubes. This effectively removes dust, dirt, and other impurities from the surface of the vacuum tubes, eliminating the need for manual climbing for cleaning, improving the convenience and safety of cleaning, and ensuring the heat collection effect of the collector 2.

[0031] Specifically, such as Figure 4 As shown, the cleaning component 6 includes a mounting base 61. The center of the mounting base 61 is fixedly connected to the movable crossbeam 5 by fixing bolts 65. Upper connecting sleeves 62 are fixedly connected to both sides of the lower end face of the mounting base 61. A lower connecting sleeve 63 is detachably connected to the lower end of the upper connecting sleeve 62. Cleaning brushes 64 are fixedly connected to the inner sides of both the upper and lower connecting sleeves 62 and 63. The two cleaning brushes 64, when combined, form a ring around the vacuum tube and contact the surface of the vacuum tube. During cleaning, the moving cleaning brushes 64 move along the outer surface of the vacuum tube to remove dust and stains, and the ring-shaped cleaning brushes 64 also ensure thorough cleaning.

[0032] Among them, the cleaning brush 64 can be made of nylon filaments. Nylon material has stable chemical properties and is resistant to acid and alkali corrosion. Even when used in complex outdoor environments, it is not easy to age or deteriorate, which can ensure the service life of the cleaning brush 64.

[0033] In addition, to further facilitate later maintenance and replacement, the outer ends of the splice of the upper connecting sleeve 62 and the lower connecting sleeve 63 are provided with protruding connecting seats. The upper and lower connecting seats are fixed together by bolts. The upper and lower connecting sleeves adopt a split and detachable connection structure design, which makes replacement and disassembly quick and convenient and highly practical.

[0034] like Figure 2As shown, a heat exchange tube 11 is installed inside the water storage tank 1. The heat exchange tube 11 is in the shape of a spiral tube, which is suitable for increasing the heat exchange area. The upper end of the heat exchange tube 11 is connected to the second pipe 10, and the lower end is connected to the first pipe 8.

[0035] like Figure 5 As shown, a guide rod 7 is fixedly connected to the side of the collector 2 away from the linear module 4, and the tilt angle of the guide rod 7 is the same as the tilt angle of the vacuum tube of the collector 2; a connecting frame 12 is fixed to the end of the movable crossbeam 5 away from the linear module 4, and a guide sleeve 13 is fixed to the lower end of the connecting frame 12, and the guide sleeve 13 is slidably sleeved on the outer end of the guide rod 7.

[0036] Since the span of the moving beam 5 is large, connecting the guide sleeve 13 and the guide rod 7 at its end can effectively support the moving beam 5, prevent the vacuum tube from bearing the weight, and also improve the movement stability of the moving beam 5.

[0037] like Figure 2 As shown, the outer side of the linear module 4 is covered with a protective shell 3, and the inner side of the protective shell 3 is open, which is suitable for the vertical movement of the moving crossbeam 5. The protective shell 3 is made of stainless steel, which is corrosion-resistant and has high strength, and is used to protect the linear module 4 and improve its service life.

[0038] like Figure 1 As shown, a circulating pump 9 is installed at the outer end of the first pipeline 8 to drive the heat transfer medium to circulate in the pipeline.

[0039] Working principle: When this solar heating box is working, the collector 2 absorbs solar energy and transfers the heat to the internal heat transfer medium. Under the action of the circulating pump 9, the heat transfer medium flows into the spiral heat exchange tube 11 in the water storage tank 1 through the first pipeline 8. Due to the spiral structure of the heat exchange tube, the heat exchange area is increased, and it can more fully exchange heat with the water in the water storage tank 1, transferring the heat to the water in the water storage tank 1 to achieve heat storage.

[0040] When the vacuum tubes of collector 2 need to be cleaned, the linear module 4 is activated. The linear module 4 drives the moving beam 5 to move up and down along the guide rod 7. The cleaning component 6 on the moving beam 5 moves with the moving beam 5. The cleaning brush 64 in the cleaning component 6 contacts the surface of the vacuum tube. During the up and down movement, it cleans the dust, dirt and other impurities on the outer surface of the vacuum tube to ensure that the vacuum tube maintains good heat collection efficiency. When not in use, the linear module 4 moves the moving beam 5 to a high position, so that the cleaning component 6 moves to the low temperature position at the end of the vacuum tube to prevent the vacuum tube from being blocked. It also avoids direct contact with high temperature areas and protects the service life of the cleaning brush 64.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
