Description

Technical Field

[0001] This application relates to the technical field of solar water heater installation, and in particular to an installation structure for a flat-plate wall-mounted solar water heater. Background Technology

[0002] A solar water heater is a device that uses solar energy to heat water. It absorbs solar radiation energy through a collector and converts solar energy into heat energy to provide hot water for homes, businesses, and industries. Its working principle is based on heat conduction and convection. After the collector absorbs sunlight, it transfers heat to the water or heat transfer medium and then stores the heated water in an insulated water tank for use.

[0003] The typical installation method for solar water heaters involves mounting the collector and water tank on the roof of a building to make full use of roof space and sunlight resources. This method is suitable for detached houses or low-rise buildings. Flat-plate wall-mounted solar water heaters, on the other hand, are solar water heating systems in which both the collector and water tank are mounted on the exterior wall of the building. They combine the high-efficiency heat collection capacity of flat-plate collectors with the convenience of wall-mounted installation, making them particularly suitable for urban residences and high-rise buildings with limited space.

[0004] For example, the wall-mounted flat-plate high-efficiency solar water heater and its installation structure with application number CN200810018505.5 improves the overall heat preservation performance of the flat-plate solar water heater by preventing heat loss through heat loss prevention treatment of the flat-plate solar collector, insulated water tank and heat transfer medium pipe. This enables the solar water heater to achieve a more ideal hot water supply effect under the same heat absorption conditions. At the same time, according to the structural characteristics of balconies in high-rise buildings, a balcony installation structure for flat-plate solar water heaters is provided, so that every household in high-rise buildings can install flat-plate high-efficiency solar water heaters on the lower wall of their balcony.

[0005] However, the aforementioned existing technologies still have some shortcomings when dealing with flat-panel wall-mounted installation structures:

[0006] In the aforementioned prior art, the water heater is integrated with the balcony of a high-rise building. The flat-plate solar collector is installed on a prefabricated wall under the balcony, and the insulated water tank is installed in a pre-reserved wall hole in the balcony wall. The collector and the water tank are connected by a heat transfer medium pipe. However, the position of the sun changes constantly throughout the day. From sunrise to sunset, the collector plate cannot automatically adjust to follow the movement of the sun. This results in the collector plate not maximizing the absorption of solar energy for most of the day.

[0007] Meanwhile, the solar altitude angle varies with the seasons throughout the year, being higher in summer and lower in winter. Existing fixed-angle adjustment mechanisms cannot adapt to this seasonal variation, further limiting the solar energy absorption efficiency of the solar collectors in different seasons.

[0008] In addition, some users' installation locations are not in the optimal sunlight exposure areas, such as being located on the north side of a building or being blocked by other buildings, resulting in less sunlight being received by the solar collector.

[0009] Based on this, and given the above viewpoints, there is still room for improvement in the existing technology for flat-panel wall-mounted installation structures. Summary of the Invention

[0010] To solve the above-mentioned technical problems, this application provides an installation structure for a flat-plate wall-mounted solar water heater, adopting the following technical solution:

[0011] A flat-plate wall-mounted solar water heater installation structure includes a water tank and a collector plate. The water tank is provided with multiple detachable arc-shaped base plates. The lower ends of the multiple arc-shaped base plates are provided with a mounting base plate. Mounting brackets are provided on both sides of the mounting base plate.

[0012] The mounting frame includes symmetrically arranged wing plates at the bottom of the mounting base plate, and support vertical plates connected to the corresponding wing plates on both sides of the mounting base plate. The support vertical plates are detachably connected to the mounting base plate and the wing plates.

[0013] Preferably, the mounting bracket also includes a rotating shaft on the support plate, and a turntable corresponding to the water tank is mounted on the rotating shaft, with the turntable connected to the water tank.

[0014] Preferably, the water tank is equipped with a sunshade that is rotatably connected to the two turntables;

[0015] The sunshade includes an arc-shaped cover plate, with arc-shaped support plates on both sides of the arc-shaped cover plate that are connected to a turntable.

[0016] Preferably, the curved cover plate has several ventilation holes.

[0017] Preferably, multiple support rods are symmetrically arranged at the upper end of the arc-shaped cover plate, and the upper ends of the multiple support rods are connected to the heat collection plate.

[0018] Preferably, the sunshade is equipped with an angle adjuster;

[0019] The angle adjuster includes a support rod mounted on a rotating shaft, the upper end of which is connected to the heat collection plate, and two arc-shaped support plates that are rotatably connected to the turntable.

[0020] A drive shaft is rotatably inserted between the two arc-shaped support plates, and the two ends of the drive shaft rotatably pass through the support rods.

[0021] Preferably, the turntable is provided with an arc-shaped rack, and the drive shaft is provided with a drive gear that meshes with the arc-shaped rack.

[0022] Preferably, the support rod includes a horizontal bar connected to the arc-shaped cover plate, a vertical bar slidably passing through one end of the horizontal bar, and the upper end of the vertical bar slidably connected to the heat collection plate.

[0023] Preferably, a return spring is fitted on the vertical rod between the horizontal rod and the heat collection plate.

[0024] Preferably, the support rod includes a fixed section and a telescopic section, the fixed section being rotatably connected to the rotating shaft, and the telescopic section being hinged to one side of the heat collection plate;

[0025] The telescopic section is provided with a clearance groove, and the fixed section is rotatably provided with an adjusting screw located in the clearance groove. The upper end of the adjusting screw rotates through the telescopic section and engages with its thread.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the cooperation of the angle adjuster and the transmission gear, the solar collector plate can automatically adjust its angle according to the position of the sun, always maintaining the optimal orientation, thereby maximizing the absorption of solar energy and improving the heat collection efficiency. The automatic tracking function is particularly suitable for different seasons and geographical locations, and can effectively cope with changes in the solar altitude angle, ensuring efficient heat collection throughout the year.

[0028] 2. The arc-shaped design of the arc-shaped cover of this invention can effectively block sunlight from different angles, preventing direct sunlight from hitting the water tank and heat collector. Combined with the angle adjuster, the sunshade can rotate with the movement of the sun, always providing the best sunshade effect.

[0029] 3. The design of the telescopic section and adjusting screw in this invention allows for precise adjustment of the tilt angle of the heat collection plate, adapting to different installation environments and user needs. By raising one side of the telescopic section and lowering the other side, bidirectional deflection of the heat collection plate can be achieved, further enhancing its adaptability to different sunlight conditions.

[0042] The following combination Figures 1 to 11 This application will be described in further detail.

[0043] This application discloses an installation structure for a flat-plate wall-mounted solar water heater, which can ensure that the collector plate can automatically adjust its angle according to the position of the sun and always maintain the best orientation, thereby maximizing the absorption of solar energy and improving the heat collection efficiency.

[0044] Example 1:

[0045] Reference Figure 1 and Figure 2As shown, a flat-plate wall-mounted solar water heater installation structure includes a water tank 1 and a collector plate 2. The water tank 1 is the core component of the water heater, used to store heated water. The collector plate 2 is a device specially designed to collect and convert solar energy. It absorbs visible light and near-infrared radiation from sunlight, converts it into heat energy, and transfers this heat energy to a heat transfer medium (such as water, antifreeze, or air), thereby realizing the collection and utilization of heat energy.

[0046] The water tank 1 is equipped with multiple detachable arc-shaped base plates 3, and the lower ends of the multiple arc-shaped base plates 3 are all equipped with mounting base plates 4. Mounting brackets 5 are provided on both sides of the mounting base plates 4. During installation, the mounting brackets 5 are fixed in a suitable position according to the installation location so that the heat collection plate 2 faces the side with sufficient sunlight.

[0047] Reference Figure 2 , Figure 3 and Figure 4 As shown, specifically, the mounting frame 5 includes wing plates 51 symmetrically arranged at the bottom of the mounting base plate 4. The wing plates 51 increase the stability and load-bearing capacity of the mounting frame 5 and prevent the mounting frame 5 from tilting or moving under the action of wind or other external forces. Supporting vertical plates 52 connected to the corresponding wing plates 51 are provided on both sides of the mounting base plate 4, and the supporting vertical plates 52 are detachably connected to the mounting base plate 4 and the wing plates 51.

[0048] During installation, two support vertical plates 52 are installed on the roof according to the installation position. A rotating shaft 53 is provided on the support vertical plate 52, and a turntable 54 corresponding to the water tank 1 is provided on the rotating shaft 53. The water tank 1 is installed in the predetermined position by connecting the turntable 54 to the water tank 1. A sunshade 6 is provided on the water tank 1 and is rotatably connected to the two turntables 54. The sunshade 6 is used to block sunlight and prevent the water tank 1 from being directly exposed to sunlight.

[0049] Multiple support rods 64 are symmetrically arranged on the upper end of the sunshade 6. The upper ends of the multiple support rods 64 are connected to the heat collection plate 2. The support rods 64 support the heat collection plate 2, so that the heat collection plate 2 faces the side with sufficient sunlight, so as to absorb visible light and near-infrared radiation in sunlight and convert them into heat energy.

[0050] When installed on an exterior wall, if the exterior wall receives sufficient sunlight, install the two support vertical plates 52 on the exterior wall so that the mounting bracket 5 is parallel to the exterior wall. The water tank 1 is then parallel to the exterior wall via the mounting bracket 5. At this time, the support rod 64 supports the heat collection plate 2 so that it faces the side with sufficient sunlight. If the exterior wall receives insufficient sunlight, install the support vertical plate 52 on only one side. Install the support vertical plate 52 on the wall so that the mounting base plate 4 is perpendicular to the wall. The heat collection plate 2 is then faced the side with sufficient sunlight via the support rod 64.

[0051] The sunshade 6 includes an arc-shaped cover plate 61, with arc-shaped support plates 62 on both sides of the arc-shaped cover plate 61 that are rotatably connected to the turntable 54. The arc-shaped cover plate 61 has several ventilation holes 63. The arc-shaped cover plate 61 blocks some sunlight, preventing the water tank 1 from overheating. The design of the ventilation holes 63 promotes air circulation, reduces the internal temperature of the sunshade 6, and further improves the heat dissipation effect of the system. Multiple support rods 64 are symmetrically arranged at the upper end of the arc-shaped cover plate 61, and the upper ends of the multiple support rods 64 are connected to the heat collection plate 2.

[0052] Reference Figure 5 , Figure 6 and Figure 7 As shown, an angle adjuster 7 is also provided on the sunshade 6. The angle adjuster 7 can also be designed to be electrically adjustable, and automatic adjustment can be achieved through a small motor and control system. The angle adjuster 7 controls the sunshade 6 to rotate as the sun moves. The heat collection plate 2 is connected to the sunshade 6 through the support rod 64 and also adjusts its angle accordingly to ensure that it always faces the sun at the best angle, improves the solar energy absorption efficiency, and at the same time enables the sunshade 6 to effectively block the sun.

[0053] Specifically, the angle adjuster 7 includes a support rod 71 mounted on a rotating shaft 53. The upper end of the support rod 71 is connected to the heat collection plate 2, and two arc-shaped support plates 62 are rotatably connected to the turntable 54. A drive shaft 72 is rotatably inserted between the two arc-shaped support plates 62. The two ends of the drive shaft 72 rotatably pass through the support rod 71, and the rotating shaft 53 is fixed on the mounting bracket 5 to provide a fulcrum for the support rod 71 and the drive shaft 72.

[0054] The motor drives the transmission shaft 72 to rotate, which in turn drives the transmission gear 74 mounted on it. The transmission gear 74 meshes with the arc-shaped rack 73 mounted on the turntable 54, forcing the two arc-shaped support plates 62 to rotate together with the arc-shaped cover plate 61. Since the support rod 64 is mounted on the arc-shaped cover plate 61, the support rod 64 and the support rod 71 drive the heat collection plate 2 to rotate together, so that the heat collection plate 2 always faces the sun. At the same time, the rotation of the arc-shaped cover plate 61 changes the angle of the sunshade 6, allowing it to be adjusted according to the position of the sun.

[0055] Continue to refer to Figure 2 , Figure 3 and Figure 4 As shown, the support rod 71 includes a fixed section 711 and a telescopic section 712. The fixed section 711 is rotatably connected to the rotating shaft 53, and the telescopic section 712 is hinged to one side of the heat collection plate 2. An avoidance groove 713 is provided on the telescopic section 712. An adjusting screw 75 located in the avoidance groove 713 is rotatably provided on the fixed section 711. The upper end of the adjusting screw 75 rotatably passes through the telescopic section 712.

[0056] By rotating the adjusting screw 75 on one side, the adjusting screw 75 engages with the threaded section 712, causing the telescopic section 712 to extend and retract within the fixed section 711. When the telescopic section 712 on one side moves into the fixed section 711, the telescopic section 712 will, through its hinge with the heat collection plate 2, cause one side of the heat collection plate 2 to deflect downwards. Conversely, by rotating the adjusting screw 75 on one side, the adjusting screw 75 engages with the threaded section 712, causing the telescopic section 712 to extend and retract within the fixed section 711.

[0057] When the telescopic section 712 on one side moves outward toward the fixed section 711, the telescopic section 712 will drive one side of the heat collection plate 2 to deflect upward through the hinge with the heat collection plate 2; by changing the tilt angle of the heat collection plate 2, it can adapt to a wider range of installation environments and usage scenarios.

[0058] The support rod 64 includes a horizontal rod 641 connected to the arc-shaped cover plate 61. A vertical rod 642 is slidably passed through one end of the horizontal rod 641. The upper end of the vertical rod 642 is slidably hinged to the heat collection plate 2. When the heat collection plate 2 deflects to one side, the vertical rod 642 on the deflected side moves downward together with the sliding hinge to the heat collection plate 2 and compresses the return spring 643 sleeved on the vertical rod 642, which is located between the horizontal rod 641 and the heat collection plate 2. The return spring 643 provides continuous support force to ensure that the heat collection plate 2 does not loosen or shake during the deflection process.

[0059] The deflection angle can be increased by raising the telescopic end on one side and lowering the telescopic section 712 on the other side. In addition, the end of the telescopic section 712 is constructed as a telescopic structure to cooperate with the deflection of the heat collection plate 2 for telescopic movement.

[0060] Example 2:

[0061] Reference Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, based on Embodiment 1, heat is collected on the heat collector plate 2 through heat collector tubes. The heat collector plate 2 is equipped with a dust collector 8 for removing dust from the heat collector tubes. The dust collector 8 can effectively keep the surface of the heat collector plate 2 clean, reduce the obstruction of dust and dirt, improve the absorption efficiency of solar energy, and at the same time, under special weather conditions, the dust collector 8 can also withstand the erosion of harsh environments such as wind, sand, rain and snow, and extend the service life of the heat collector plate 2 and the heat collector tubes.

[0062] Specifically, the dust collector 8 includes a dust removal scraper 81 that is slidably disposed on the heat collection plate 2. The dust removal scraper 81 has dust removal holes 82 that correspond one-to-one with the heat collection tubes. The dust removal holes 82 are slidably connected to the heat collection tubes. Sliding grooves 83 are symmetrically disposed on both sides of the heat collection plate 2. Connecting blocks 84 that are connected to the dust removal scraper 81 are slidably disposed in the sliding grooves 83.

[0063] A pin hole 85 is provided on one side of the sliding groove 83. A pin 86 is slidably disposed in the pin hole 85. The pin 86 has a pin groove 88. A retaining spring 89 is provided between the pin groove 88 and the pin hole 85.

[0064] During the day, when the heat collector plate 2 faces the sun, it tilts to one side, and the dust removal scraper 81 is located on the lower side of the tilt. When the heat collector plate 2 rotates to the other side, the pin 86 will abut against the connecting block 84 to restrict the movement of the dust removal scraper 81 until the heat collector plate 2 rotates to the limit position on the other side. The guide 9 provided on the wing plate 51 will pull the pin 86 through the connection with the pin 86, so that the pin 86 moves into the pin hole 85 and compresses the clamping spring 89. At this time, the dust removal scraper 81 will move along the tilt direction under the action of gravity, and the heat collection tube will pass through the dust removal hole 82. During the movement of the dust removal scraper 81, the dust removal hole 82 contacts the surface of the heat collection tube and removes the dust and dirt from the surface of the heat collection tube.

[0065] When the heat collector plate 2 faces the sun again, it will tilt to one side. The dust scraper 81 will guide it to one side to clean the heat collector tube again. At the same time, the dust scraper 81 will drive the connecting block 84. The connecting block 84 will abut against the guide slope 87 on the side of the pin 86 away from the connecting block 84, so that the pin 86 will be retracted into the pin hole 85 and the clamping spring 89 will be compressed. This will allow the connecting block 84 to pass smoothly through the pin 86 to one side of the heat collector plate 2, so that it returns to its initial state.

[0066] Through the cooperation of pin 86, connecting block 84 and guide 9, the dust removal scraper 81 is automatically cleaned and reset during the rotation of the heat collector plate 2 without manual intervention. During the movement, the dust removal scraper 81 contacts the surface of the heat collector tube through the dust removal hole 82, which can effectively remove dust and dirt from the surface of the heat collector tube and the heat collector plate 2. The dust removal scraper 81 and the connecting block 84 are made of wear-resistant materials and can withstand long-term use and frequent movement.

[0067] The guide 9 includes a rotating shaft 91 mounted on a wing plate 51 via a bracket, a winding wheel 92 rotatably mounted on the rotating shaft 91 via a spiral spring, a guide wheel 93 corresponding to the pin hole 85 at the lower end of the heat collection plate 2, a traction line 94 wound on the winding wheel 92, and the traction line 94 passes around the guide wheel 93 and connects to the corresponding pin 86.

[0068] In the initial state, the traction line 94 is wound on the winding wheel 92, and the elastic force of the clamping spring 89 is greater than the tightening force of the spiral spring. When the heat collection plate 2 deflects to the other side, the winding wheel 92 rotates to release the guide line and gradually tightens the spiral spring until the heat collection plate 2 rotates to the limit position on the other side. At this time, the tightening force of the spiral spring is greater than that of the clamping spring 89. At this time, the traction line 94 will pull the pin 86, so that the pin 86 retracts into the pin hole 85, allowing the connecting block 84 to pass smoothly.

[0069] Additionally, a bracket 95 is provided on one side of the heat collection plate 2, and a folding guard plate 96 is provided on the bracket 95. One end of the folding guard plate 96 is connected to the dust removal scraper 81. When the dust removal scraper 81 moves, the folding guard plate 96 will move along with it and unfold accordingly. The folding guard plate 96 unfolds during the movement of the dust removal scraper 81 and covers the surface of the heat collection plate 2, preventing dust from falling back onto the heat collection plate 2 during the cleaning process and enhancing the dust removal effect. At the same time, the connection design of the folding guard plate 96 with the dust removal scraper 81 and the bracket 95 ensures that it remains stable during movement and unfolding and is not prone to jamming or damage.

[0070] In windy and sandy weather conditions, the folding protective plate 96 can be unfolded to prevent wind and sand from directly impacting the surface of the heat collection plate 2, thus avoiding wear or damage to the heat absorption coating.

[0071] The folding protective panel 96 is made of transparent materials, such as polycarbonate (PC) or tempered glass. These materials have good light transmittance and weather resistance, which can effectively protect the collector panel 2 without affecting the absorption of solar energy.

[0072] The implementation principle of this invention is as follows:

[0073] (1): During installation, the two support vertical plates 52 can be installed on the roof according to the installation position. The water tank 1 is installed in the predetermined position by connecting the turntable 54 to the water tank 1. The water tank 1 is provided with a sunshade 6 that is rotatably connected to the two turntables 54. The sunshade 6 is used to block the sunlight and prevent the water tank 1 from being directly exposed to the sunlight.

[0074] (2): When installed on an exterior wall, if the exterior wall has sufficient sunlight, install two support vertical plates 52 on the exterior wall so that the mounting bracket 5 is parallel to the exterior wall. The water tank 1 is parallel to the exterior wall through the mounting bracket 5. At this time, the support rod 64 supports the heat collection plate 2 so that it faces the side with sufficient sunlight. If the exterior wall has insufficient sunlight, only install the support vertical plate 52 on one side. Install the support vertical plate 52 on the wall so that the mounting base plate 4 is perpendicular to the wall. The heat collection plate 2 faces the side with sufficient sunlight through the support rod 64.

[0075] (3): The drive shaft 72 is driven to rotate by the motor. The rotating drive shaft 72 will drive the drive gear 74 set on it. The drive gear 74 will mesh with the arc rack 73 set on the turntable 54, forcing the two arc support plates 62 to drive the arc cover plate 61 to rotate together. Since the support rod 64 is set on the arc cover plate 61, the support rod 64 and the support rod 71 will drive the heat collection plate 2 to rotate together, so that the heat collection plate 2 always faces the sun.

[0076] (4): At the same time, the rotation of the arc-shaped cover plate 61 changes the angle of the sunshade 6, so that it can be adjusted according to the position of the sun. The sunshade 6 can rotate with the movement of the sun, always providing the best sunshade effect.

[0077] (5): Angle adjustment. When it is necessary to adjust the tilt angle of the heat collection plate 2, for example by manual adjustment or starting the automatic control system, the vertical rod 642 on the deflected side will start to move. Since the vertical rod 642 is connected to the heat collection plate 2 by a sliding hinge, the vertical rod 642 will move downward and compress the return spring 643 sleeved on the vertical rod 642.

[0078] (6): Deflection motion. The extension and retraction motion of the telescopic section 712 is transmitted through the hinge point with the heat collection plate 2, which drives the heat collection plate 2 to deflect. Specifically, when one side of the telescopic section 712 is raised, the heat collection plate 2 will deflect downward, thereby changing its tilt angle and ensuring that the heat collection plate 2 can be accurately adjusted to the required angle.

[0079] (7): When the heat collection plate 2 rotates to the limit position on the other side, the guide 9 provided on the wing plate 51 will pull the pin 86 through the connection with the pin 86, so that the pin 86 moves into the pin hole 85 and compresses the clamping spring 89. At this time, the dust removal scraper 81 will move along the inclined direction under the action of gravity, and the heat collection tube will pass through the dust removal hole 82. During the movement of the dust removal scraper 81, the dust removal hole 82 contacts the surface of the heat collection tube and removes the dust and dirt on the surface of the heat collection tube.

[0080] (8): Through the cooperation of the pin 86, the connecting block 84 and the guide 9, the dust removal scraper 81 is automatically cleaned and reset during the rotation of the heat collection plate 2 without manual intervention. During the movement, the dust removal scraper 81 contacts the surface of the heat collection tube through the dust removal hole 82, which can effectively remove dust and dirt from the surface of the heat collection tube and the heat collection plate 2. The dust removal scraper 81 and the connecting block 84 are made of wear-resistant materials and can withstand long-term use and frequent movement.

[0081] (9): When the dust removal scraper 81 moves, the folding guard plate 96 will move along with it and unfold accordingly. The folding guard plate 96 unfolds during the movement of the dust removal scraper 81 and covers the surface of the heat collection plate 2 to prevent dust from falling back onto the heat collection plate 2 during the cleaning process, thereby enhancing the dust removal effect. At the same time, the connection design between the folding guard plate 96, the dust removal scraper 81, and the bracket 95 ensures that it remains stable during movement and unfolding, and is not prone to jamming or damage.

[0082] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
