Description

Technical Field

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

[0002] Distributed solar heating systems are innovative systems that utilize solar energy to provide heating for buildings. Their core component is the solar collector, typically installed in a distributed manner on rooftops or other sunny areas. By absorbing solar energy, the collector converts light energy into heat energy, heating the heat transfer medium (such as water or antifreeze), and then delivering the hot water to the heating terminals (such as underfloor heating, radiators, or fan coil units) to meet the building's heating needs. This system not only achieves efficient use of clean energy but also reduces the consumption of traditional fossil fuels and carbon emissions. Suitable for residential, community, and commercial buildings, distributed solar heating systems demonstrate significant economic and environmental advantages, especially in areas with abundant sunshine. However, existing distributed solar heating systems do not easily adjust the heating direction of the solar collectors according to the angle of sunlight during the heating process, thus failing to fully absorb solar energy and reducing the heating efficiency of the distributed solar heating system.

[0003] For example, Chinese patent CN209524564U discloses a distributed heating device, including a plate solar heater, a heat storage chamber, heat sinks, a first water pump, a second water pump, a processing tank, a stirring motor, a filter pipe, a filter screen, etc.

[0004] This distributed heating system has the following drawbacks: Although it can clean scale in the water, improve the protection of the panel solar heaters and radiators, and ensure their service life, it is not convenient to adjust the heating direction of the solar collectors according to the angle of the sun during the heating process, and it cannot fully absorb solar energy, thus reducing the heating efficiency of the distributed solar heating system.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a distributed solar heating device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A distributed solar heating device includes a plate solar collector. An adjustment assembly is connected to one side wall of the bottom of the plate solar collector to adjust its angle. A support column is located at the bottom of the adjustment assembly, and a storage tank is located at the bottom of the support column. The storage tank contains a cold water storage chamber and a hot water storage chamber, arranged sequentially from left to right. A cold water hose is connected to one bottom end of the plate solar collector, and a water pump is connected to the end of the cold water hose. A pump has a pump pipe extending through one side wall of the storage tank into the cold water storage chamber. A fixing plate is fixedly connected to one side wall of the storage tank at the bottom of the pump. A hot water hose is connected to the top of the heater, and a second water pump is connected to the end of the hot water hose. A fixed base is provided at the bottom of the second water pump, which is fixedly connected to the top of the storage tank. A water inlet pipe is connected to the bottom of the second water pump, which passes through the top of the fixed base and the top of the storage tank and extends into the hot water storage chamber. A filter assembly that cooperates with the water inlet pipe is inserted through one side wall of the storage tank. A hot water supply pipe is provided through one side wall of the bottom of the storage tank. A control panel is provided on the front of the storage tank. A cold water supply pipe is provided through the other side wall of the bottom of the storage tank. A photosensor that cooperates with the adjustment assembly is provided on the top of one side of the plate solar collector, and the photosensor is arranged parallel to the plate solar collector.

[0009] Furthermore, in order to enable the panel solar collector to adjust its direction according to the movement of the sun under the action of the adjustment component, thereby maximizing the heating efficiency of the panel solar collector and thus improving the heating efficiency of the distributed solar heating device, and avoiding insufficient solar energy absorption, the adjustment component includes a ring set at the top of the support column. A movable component is set at the top of the ring, and an inclined block that cooperates with the panel solar collector is set at the top of the movable component. The movable component includes a square shell set outside the top of the ring. A servo motor is set on one side of the inner top of the square shell. The output end of the servo motor is connected to a gear. A limiting groove that cooperates with the ring is opened on one side of the bottom of the square shell. An annular groove is opened on the inner wall of the ring, and several tooth grooves that mesh with the gear are set on the inner wall of the annular groove.

[0010] Furthermore, in order to achieve multi-stage filtration of the heat transfer medium converted into heat energy under the action of the filtration component, and to avoid the phenomenon that scale in the heat transfer medium causes blockage at the heating terminal and affects the subsequent heating efficiency, the filtration component includes several sliding grooves opened on one side wall of the storage tank. Each sliding groove is equipped with a filter plate, and each filter plate has several filter holes at its top. Handles are symmetrically arranged at both ends of one side wall of the filter plate. A limit plate is set in the middle of one side wall of the filter plate. A bolt that mates with one side wall of the storage tank is installed through the top side wall of the limit plate. Cross-shaped limit sliders are set at both ends of the filter plate. Cross-shaped sliding grooves that mate with the cross-shaped limit sliders are opened at both ends of the sliding grooves. The diameter of the filter holes on the filter plates decreases sequentially from top to bottom.

[0011] The beneficial effects of this utility model are as follows:

[0026] According to an embodiment of the present invention, a distributed solar heating device is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, the distributed solar heating device according to an embodiment of this utility model includes a plate solar collector 1. An adjustment assembly 2 is connected to one side wall of the bottom of the plate solar collector 1. The angle of the plate solar collector 1 can be adjusted by the adjustment assembly 2. A support column 3 is provided at the bottom end of the adjustment assembly 2, and a storage tank 4 is provided at the bottom end of the support column 3. In specific applications, a bolt hole for cooperating with a bolt 156 is opened on one side wall of the storage tank 4. A cold water storage chamber 5 and a hot water storage chamber 6 are sequentially opened from left to right inside the storage tank 4. A cold water hose 7 is connected to one bottom end of the plate solar collector 1, and a water pump 8 is connected to the end of the cold water hose 7. A water pump 8 extends through one side wall of the storage tank 4 via a pumping pipe 9 and into the cold water storage chamber 5. A fixing plate 1 is provided at the bottom end of the water pump 8 and is fixedly connected to one side wall of the storage tank 4. 0. A hot water hose 11 is connected to the top end of the plate solar collector 1. A water pump 12 is connected to the end of the hot water hose 11. A fixing seat 13 is fixedly connected to the top of the storage tank 4 at the bottom end of the water pump 12. A water inlet pipe 14 is connected to the bottom end of the water pump 12, passing through the top of the fixing seat 13 and the top of the storage tank 4 and extending into the hot water storage chamber 6. A filter assembly 15 that cooperates with the water inlet pipe 14 is inserted through one side wall of the storage tank 4. A hot water supply pipe 16 is inserted through one side wall of the bottom of the storage tank 4. A control panel 17 is provided on the front of the storage tank 4. A cold water supply pipe 18 (i.e., the return pipe of the heating terminal) is inserted through the other side wall of the bottom of the storage tank 4. A photosensor 19 that cooperates with the adjustment assembly 2 is provided on the top side of one side of the plate solar collector 1. The photosensor 19 is arranged parallel to the plate solar collector 1.

[0028] Furthermore, the working principles and structures of the plate solar collector 1, servo motor 2022, photosensitive sensor 19, water pump 18, and water pump 212 are all existing technologies, and will not be elaborated on here.

[0029] It should be explained that the photosensitive sensor 19 is used to detect the position and intensity of the sun and track its movement in real time. The photosensitive sensor 19 senses the direction and intensity of sunlight through a photosensitive element (such as a photodiode) and transmits the signal to the control panel 17. The control panel 17 then outputs instructions to the servo motor 2022. According to the instructions of the control panel 17, the servo motor 2022 precisely adjusts the position of the plate solar collector 1 to achieve automatic tracking of the plate solar collector 1 and ensure maximum solar energy absorption.

[0030] In one embodiment, the adjustment component 2 includes a ring 201 disposed at the top of the support column 3. A movable element 202 is disposed at the top of the ring 201, and an inclined block 203 cooperating with the plate solar collector 1 is disposed at the top of the movable element 202. The movable element 202 includes a square housing 2021 disposed outside the top of the ring 201. A servo motor 2022 is disposed on one side of the inner top of the square housing 2021, and a gear 2023 is connected to the output end of the servo motor 2022. The bottom side of the plate solar collector 1 is provided with a limiting groove 2024 that cooperates with the ring 201. The inner wall of the ring 201 is provided with an annular groove 2011. The inner wall of the annular groove 2011 is provided with a number of tooth grooves 2012 that mesh with the gear 2023. Under the action of the adjusting component 2, the plate solar collector 1 can adjust its direction to follow the movement of the sun, thereby maximizing the heating efficiency of the plate solar collector 1 and thus improving the heating efficiency of the distributed solar heating device, avoiding the phenomenon of insufficient solar energy absorption.

[0031] The specific working principle of the adjustment component 2 is as follows: When the plate solar collector 1 is exposed to direct sunlight, the photosensitive sensor 19 automatically controls the switching on and off of the servo motor 2022 circuit. When the photosensitive sensor 19 is not exposed to direct sunlight, the servo motor 2022 circuit is connected, driving the gear 2023 to rotate through the output of the servo motor 2022. With the cooperation of the gear 2023 and the tooth groove 2012, the square housing 2021 is driven to perform circular motion on the ring 201 under the action of the limiting slide groove 2024. Under the action of the square housing 2021, the tilting block 203 is driven to move. Under the action of 203, the angle of the plate solar collector 1 is adjusted so that the plate solar collector 1 is always facing the sun according to the direction of the sun. When the angle of the plate solar collector 1 is adjusted to face the sun, the photosensitive sensor 19 is directly exposed to the sun and disconnects the circuit, causing the servo motor 2022 to stop working. Thus, the position of the plate solar collector 1 can be adjusted in real time according to the position of the sun, so as to maximize the heating efficiency of the plate solar collector 1 and improve the heating efficiency of the distributed solar heating device, thereby avoiding the phenomenon of insufficient solar energy absorption.

[0032] In one embodiment, the filter assembly 15 includes several grooves 151 formed on one side wall of the storage tank 4. Each groove 151 is equipped with a filter plate 152. Each filter plate 152 has several filter holes 153 at its top. Handles 154 are symmetrically arranged at both ends of one side wall of the filter plate 152. A limiting plate 155 is provided in the middle of one side wall of the filter plate 152. A bolt 156 that cooperates with one side wall of the storage tank 4 is provided through the top side wall of the limiting plate 155. Cross-shaped limiting sliders 157 are provided at both ends of the filter plate 152. Cross-shaped grooves 158 that cooperate with the cross-shaped limiting sliders 157 are provided at both ends of the grooves 151. The diameter of the filter holes 153 on the filter plates 152 decreases from top to bottom, so that the heat transfer medium converted into heat energy can be filtered in multiple stages under the action of the filter assembly 15, avoiding the phenomenon that scale in the heat transfer medium causes blockage at the heating terminal and affects the subsequent heating efficiency.

[0033] The specific working principle of the filter assembly 15 is as follows: First, the water after heat energy conversion is drawn into the hot water storage chamber 6 through the water inlet pipe 14. At this time, the hot water passes through several filter plates 152 and filter holes 153 from top to bottom. Since the diameter of the filter holes 153 on the filter plates 152 decreases from top to bottom, the hot water can be filtered in multiple stages to avoid the phenomenon that scale in the hot water will cause blockage at the heating terminal and affect the subsequent heating efficiency. When it is necessary to clean the filter plate 152, the bolt 156 is turned to remove it from the side wall and the limiting plate 155 of the storage tank 4. Then, the filter plate 152 is pulled out along the slide groove 151 by the handle 154 to clean the filter plate 152 and prevent scale from causing blockage of the filter holes 153 for a long time, which would affect the subsequent filtration efficiency.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In practical applications, firstly, external domestic water is delivered to the cold water storage chamber 5 through the cold water supply pipe 18. Then, the water pump 8 is started through the control panel 17 to pump the water in the cold water storage chamber 5 into the cold water hose 7 through the pumping pipe 9. The water then enters the plate solar collector 1 through the cold water hose 7 for heat conversion. Next, the water pump 12 is started to pump the water converted by the plate solar collector 1 into the hot water storage chamber 6 through the inlet pipe 14. Then, according to demand, the hot water in the hot water storage chamber 6 is delivered to the heating terminal through the hot water supply pipe 16 to meet the heating needs of the building. When it is necessary to adjust the heating direction of the solar collector according to the angle of the sun, the plate solar collector 1 can adjust its direction to follow the movement of the sun through the action of the photosensitive sensor 19 and the adjustment component 2, thereby maximizing the heating efficiency of the plate solar collector 1.
