Description

Technical Field

[0001] This utility model relates to the technical field of solar heating equipment, specifically, to a practical solar heating device. Background Technology

[0002] In many existing solar heating systems, the solar collectors are mostly fixed installations, and their tilt angle cannot be adjusted according to the sun's position (such as the orientation at sunrise and sunset, and the altitude angle during seasonal changes). This results in low efficiency of the collectors in receiving solar radiation, especially during periods of significant changes in the angle of sunlight (such as morning, evening, or winter). The angle between the collector and the sunlight deviates from the optimal angle, and a large amount of solar energy is not effectively utilized, which in turn affects the heating efficiency of the water in the pipes and reduces the overall energy efficiency of the heating system.

[0003] In addition, the tempered transparent glass of solar collectors, as a key component for energy reception, is exposed to the outdoor environment for a long time and is prone to accumulating dust, fallen leaves, bird droppings and other debris. These pollutants will block light and further reduce the light transmittance and heat absorption efficiency of the collectors. Existing cleaning methods mostly rely on manual wiping, which is not only time-consuming and labor-intensive, but also poses safety hazards for collectors installed at high places such as rooftops.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0026] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-6 As shown, this utility model illustrates a practical solar heating device according to one embodiment of the present invention, comprising: a base 1, with support frames 2 fixedly installed at the front and rear edges of the top of the base 1, an installation frame 3 located directly above the base 1, connecting rings 4 fixedly installed on the outer walls of the front and rear ends of the installation frame 3, each set of connecting rings 4 being rotatably connected to the support frame 2 at the corresponding position, a heat-absorbing plate 5 fixedly installed inside the installation frame 3, several sets of metal tubes 6 being longitudinally embedded and fixedly installed at the bottom end of the heat-absorbing plate 5, a first cavity 7 being opened inside the outer walls of the front and rear ends of the installation frame 3, a fixing tube 8 being fixedly installed inside each set of first cavities 7, and the front and rear ends of each set of metal tubes 6 being sealed and connected to the fixing tube 8 at the corresponding position;

[0032] The connecting frame 14 is fixedly installed at both the front and rear ends of the top right side of the base 1. The ends of the two sets of connecting frames 14 that are far apart from each other are provided with arc-shaped grooves 15. The connecting plates 16 are fixedly installed at the right edges of both the front and rear ends of the mounting frame 3. Each set of connecting plates 16 is rotatably installed with a connector 17. Each set of connectors 17 is movably connected to the arc-shaped groove 15 at the corresponding position.

[0033] For example, such as Figure 3 As shown, a mounting slot 18 is provided on the top left side of the base 1. A first multi-stage cylinder 19 is rotatably mounted inside the mounting slot 18. A first telescopic rod 20 is fixedly mounted on the output end of the first multi-stage cylinder 19. The other end of the first telescopic rod 20 is rotatably connected to the bottom left edge of the mounting frame 3.

[0034] For example, such as Figure 1 As shown, each of the two sets of connecting rings 4 has a first connecting pipe 9 inside. The ends of the two sets of first connecting pipes 9 that are close to each other are sealed to the fixed pipe 8 at the corresponding position. The ends of the two sets of first connecting pipes 9 that are far apart from each other are rotatably sealed with a rotary joint 10. The ends of the two sets of rotary joints 10 that are far apart from each other are fixedly installed with a second connecting pipe 11. The front and rear ends of the base 1 are equipped with circulation pumps 12. The output end of each set of circulation pumps 12 is sealed to the second connecting pipe 11 at the corresponding position. A solenoid valve 13 is fixedly installed on each set of second connecting pipes 11.

[0035] For example, such as Figure 4 As shown, a tempered transparent glass 34 is fixedly installed at the top inside the mounting frame 3, and a base plate 35 is fixedly installed at the bottom inside the mounting frame 3. A second cavity 36 is opened inside the base plate 35, and the second cavity 36 is filled with polyurethane foam. Support plates 32 are fixedly installed at the four corners of the bottom of the base 1, and several sets of mounting holes 33 are opened on each set of support plates 32.

[0036] In some examples, this device is equipped with a centralized PLC controller. When using this device, the operator first uses bolts to install it in the designated position via the support plate 32 and mounting holes 33. Then, the PLC controller sets the corresponding program, which, according to an astronomical algorithm, activates the first multi-stage cylinder 19 based on the sun's trajectory at different time periods. This, in turn, drives the mounting frame 3 to rotate around the connecting ring 4 via the first telescopic rod 20. This allows for flexible adjustment of the collector's tilt angle based on the sun's real-time position, ensuring the mounting frame maintains the optimal angle for receiving sunlight. This significantly increases the solar energy absorption per unit time, improves the heating speed and temperature of the water in the metal pipe 6, and enhances the heating efficiency of the heating equipment. In this device, heat is transferred into the metal pipe 6 through the heat-absorbing plate 5, and then heats the water inside the metal pipe 6. During the heating process, both sets of solenoid valves 13 are closed. Then, in conjunction with the two sets of circulating pumps 12, the heated water is delivered into the underfloor heating system. Simultaneously, cooled water can enter the metal pipe 6 for heating via another set of circulating pumps 12. Furthermore, in this device, the rotary joint 10 ensures that the ends of the two sets of first connecting pipes 9, which are far apart from each other, are rotatably and sealingly connected to the rotary joint 10, and the ends of the two sets of rotary joints 10, which are far apart from each other, are fixedly connected to the second connecting pipe 11. Therefore, when the mounting frame 3 is adjusted by the first multi-stage cylinder 19, the rotation of the mounting frame 3 is prevented from affecting the pipe connections. Finally, the second cavity 36, which is opened inside the base plate 35 and filled with polyurethane foam, reduces heat loss to a certain extent, making the device more practical.

[0037] like Figure 4As shown, this is a practical solar heating device according to another embodiment of the present invention. Mounting strips 21 are horizontally fixedly installed on both the front and rear edges of the top of the mounting frame 3. Sliding grooves 22 are horizontally formed at the ends of two sets of mounting strips 21 that are close to each other. A mounting plate 24 is positioned directly above the mounting frame 3. The front and rear ends of the mounting plate 24 are slidably connected to the corresponding sliding grooves 22. A spring groove 25 is longitudinally formed at the bottom of the mounting plate 24. Sliding strips 26 are slidably installed inside the spring groove 25. Several sets of springs 27 are fixedly installed at the top of the spring groove 25. Each set of springs 27... The bottom ends are all fixedly connected to the slide bar 26. A silicone scraper 28 is fixedly installed at the bottom end of the slide bar 26. The bottom end of the silicone scraper 28 is attached to the top end of the tempered transparent glass 34. A side plate 29 is fixedly installed at the right edge of the top end of the mounting frame 3. A second multi-stage cylinder 30 is fixedly installed on the outer wall of the right side of the side plate 29. A second telescopic rod 31 is fixedly installed at the output end of the second multi-stage cylinder 30. The other end of the second telescopic rod 31 is fixedly connected to the mounting plate 24. A stabilizing rod 23 is fixedly installed inside each set of slide grooves 22. The front and rear ends of the mounting plate 24 are slidably connected to the stabilizing rod 23 at the corresponding positions.

[0038] In some examples, after prolonged or certain periods of use, the operator can activate the second multi-stage cylinder 30, which in turn causes the mounting plate 24 to slide within the slide groove 26 via the second telescopic rod 31. As the mounting plate 24 slides, the silicone scraper 28, under the action of the spring 27, closely adheres to the tempered transparent glass 34, thereby promptly removing dust, debris, and other contaminants from the surface of the tempered transparent glass 34, maintaining the glass's high light transmittance, preventing energy loss due to obstruction, and ensuring that the solar collector maintains a long-term high-efficiency heat absorption state. This also reduces the frequency and difficulty of manual operation, making it particularly suitable for solar collectors installed at high locations, reducing the safety hazards and maintenance costs of manual cleaning. Through the above-mentioned design, the practical usability of this device is further improved.

[0039] It should be noted that the PLC controller is an S7-200SMART, used to control the operating status and other parameters of various electrically driven components in the device. The circulating pump 12 is a UPB15-6, the solenoid valve 13 is a ZCS-15, and the first multi-stage cylinder 19 and the second multi-stage cylinder 30 are TCL20-10S. All of the above electrical components are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
