Description

Technical Field

[0001] This utility model belongs to the field of energy technology, and in particular relates to a thermal storage and heating device. Background Technology

[0002] Thermal energy storage (TES) heating systems are devices that utilize off-peak electricity hours or other low-cost energy sources to generate heat and store it, releasing the heat when needed to provide heating services. These systems are typically used to improve energy efficiency, reduce operating costs, and help balance grid load.

[0003] Traditional thermal energy storage heating devices typically rely solely on the thermal storage medium to directly absorb solar radiation heat energy when collecting and storing solar energy. While this method can meet basic heat storage and release requirements, the lack of an efficient optical concentrating structure makes it difficult to effectively gather and concentrate solar energy, resulting in low utilization of solar energy and failing to fully realize the heat collection potential under limited sunlight conditions. This, in turn, affects the overall thermal conversion efficiency and operational stability of the system.

[0004] Therefore, a thermal storage heating device is particularly needed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional thermal storage heating devices, which lack efficient optical concentrating structures, resulting in low solar energy utilization and affecting heat collection efficiency and system stability, this utility model provides a thermal storage heating device.

[0006] This utility model is achieved through the following technical means: a heat storage heating device, including a support base, a liquid storage tank, connecting valves, a cover plate, and a lens. The support base is installed at one end of the liquid storage tank, and two connecting valves are symmetrically installed at the bottom of the liquid storage tank. The cover plate is installed at the other end of the liquid storage tank, and the lens is embedded and fixed to the center of the upper part of the cover plate. It also includes a support ring, a reflector, a connecting shaft, a servo motor, a worm gear, and a worm wheel. The support ring is installed at one end of the liquid storage tank and is located above the support base. Two connecting shafts are rotatably arranged in parallel along the left and right directions on the support ring. A reflector is fixed to each connecting shaft. Two servo motors are installed side by side at the bottom of the support ring. The output shaft of each servo motor faces outward and is fixed to a worm gear through a coupling. A worm wheel is fixed to the middle of each connecting shaft. The number of worm wheels is the same as the number of worm gears, and they mesh with each other vertically.

[0007] As an improvement to the above solution, it also includes a connecting ring and a refractor. The connecting ring is fixed to the upper part of the cover plate, and the refractor is fixed to the annular inner wall of the connecting ring. The whole structure is a flat-topped cone with a diameter at the top larger than that at the bottom, forming a cone structure that gradually shrinks towards the center, and the bottom surface of the refractor is close to the lens.

[0008] As an improvement to the above solution, it also includes a support plate, a support shaft, a heat-absorbing film, a connecting rod, and a limiting plate. Two support plates are installed side by side on the annular outer wall of the liquid storage tank. A support shaft is rotatably installed on each support plate. The vertical height of the support shaft is consistent with that of the support plate. A heat-absorbing film is wound on each support shaft. A connecting rod made of magnetic material is fixed to the end of each heat-absorbing film that is not connected to the support shaft. Multiple limiting plates are distributed and fixed on the annular outer wall of the liquid storage tank. Each connecting rod is inserted into the slide between two corresponding limiting plates by a sliding fit.

[0009] As an improvement to the above solution, it also includes connecting covers and spiral springs. Each support shaft has a connecting cover fixedly attached to both ends, and each spiral spring is located inside each connecting cover, with its two ends fixedly connected to the corresponding connecting cover and the corresponding support shaft, respectively.

[0010] As an improvement to the above solution, a magnetic block is also included, with a magnetic block fixed between every two vertically aligned limiting plates, and the magnetic block magnetically adsorbs and engages with the corresponding connecting rod.

[0011] As an improvement to the above solution, two square slots are reserved on the support base, the number of which corresponds to the number of connecting valves, and the size of the slots is adapted to the external pipeline.

[0012] Beneficial effects: 1. The automatic angle-adjusting concentrating system, composed of a support ring, reflector, connecting shaft, servo motor, worm gear, and worm wheel, can maximize the utilization of solar energy, enhance the device's ability to capture solar energy, and adjust the angle of the reflector in real time according to the direction of sunlight, so that the reflector maintains the optimal reflection angle at different times and in different seasons, thereby reflecting more sunlight onto the surface of the liquid storage tank, achieving all-weather high-efficiency concentrating, and significantly improving the overall heat collection efficiency.

[0013] 2. Through the combined design of the connecting ring and the refracting mirror, a multi-level light-concentrating structure is formed. The refracting mirror can concentrate and guide the sunlight shining in from the outside to the lens, and then the lens can further focus it onto the heat transfer liquid in the storage tank, forming a multi-converging optical path, which greatly improves the utilization efficiency of solar energy.

[0014] 3. The auxiliary heat absorption structure, consisting of a support plate, support shaft, heat absorption film, connecting rod, and limiting plate, expands the effective heat absorption area of ​​the liquid storage tank without increasing additional energy consumption. This not only improves the solar energy absorption rate but also effectively reduces heat loss through outward radiation, thereby enhancing the overall thermal conversion efficiency of the system.

[0015] 4. The design of the connecting cover and spiral spring enables the automatic winding function of the heat-absorbing film. When the heat-absorbing film is not needed, simply release the magnetic attraction between the connecting rod and the magnetic block to quickly complete the winding of the heat-absorbing film. This protects the heat-absorbing film from environmental influences, facilitates maintenance, and extends its service life. Attached Figure Description

[0024] Example: A thermal storage heating device, such as Figures 1-4As shown, the system includes a support base 1, a liquid storage tank 2, connecting valves 201, a cover plate 3, and a lens 4. The support base 1 is bolted to the lower end of the liquid storage tank 2. Two connecting valves 201 are symmetrically bolted to the bottom of the liquid storage tank 2. The left connecting valve 201 controls the entry of the heat transfer liquid, while the right connecting valve 201 controls the discharge of the heat transfer liquid. These two connecting valves 201 facilitate the injection and discharge of the heat transfer liquid. The support base 1 has two pre-drilled square slots, the number of which corresponds one-to-one with the connecting valves 201. The slot size is adapted to the external pipeline, allowing the pipelines led out from the connecting valves 201 to pass through, facilitating neat pipe laying. The cover plate 3 is bolted to the upper end of the liquid storage tank 2. The lens 4 is embedded and welded to the center of the upper part of the cover plate 3. It has a convex lens structure, and when sunlight passes through, the lens 4 can enhance the heat focusing effect of sunlight, transferring more solar energy. The system concentrates heat transfer liquid within the storage tank 2 to improve heat collection efficiency. It also includes a support ring 7, a reflector 8, connecting shafts 9, a servo motor 10, a worm gear 11, and a worm wheel 12. The support ring 7 is bolted to the lower end of the storage tank 2 and located above the support base 1. Two connecting shafts 9 are parallel to each other and rotate on the support ring 7. Each connecting shaft 9 has a reflector 8 welded to it, reflecting sunlight to the surface of the storage tank 2 and increasing the solar energy received by the storage tank 2. Two servo motors 10 are bolted side-by-side to the bottom of the support ring 7. The output shaft of each servo motor 10 faces outwards and is fixedly connected to a worm gear 11 via a coupling. A worm wheel 12 is welded to the middle of each connecting shaft 9. The number of worm wheels 12 is the same as the number of worm gears 11, and they mesh one-to-one, allowing the servo motors 10 to drive the reflector 8 to automatically adjust its angle to adapt to different light directions and improve light concentration efficiency.

[0025] like Figure 1 As shown, it also includes a connecting ring 5 and a refractor 6. The connecting ring 5 is welded to the upper part of the cover plate 3, and the refractor 6 is welded to the annular inner wall of the connecting ring 5. Its overall shape is a flat-topped cone structure with a top diameter larger than the bottom diameter, forming a cone structure that gradually shrinks towards the center. This structure can concentrate and refract the light coming in from the outside onto the lens 4, further enhancing the collection and focusing effect of sunlight. The bottom surface of the refractor 6 is close to the lens 4, ensuring that the light can be efficiently transmitted to the lens 4 for focusing.

[0026] like Figures 3-7As shown, it also includes a support plate 13, a support shaft 14, a heat-absorbing film 15, a connecting rod 18, a limiting plate 19, and a magnetic block 20. Two support plates 13 are bolted side by side to the annular outer wall of the liquid storage tank 2. A support shaft 14 is rotatably mounted on each support plate 13. The vertical height of the support shaft 14 is consistent with that of the support plate 13. A heat-absorbing film 15 is wound up on each support shaft 14. The heat-absorbing film 15 is made of a high heat-absorbing and low-emissivity material and has good solar energy absorption capacity. A connecting rod 18 made of magnetic material is glued to the end of each heat-absorbing film 15 that is not connected to the support shaft 14. The four limiting plates 19 have... The connecting rods 18 are welded to the annular outer wall of the storage tank 2. Each connecting rod 18 is inserted into the slide between the two corresponding limiting plates 19 through a sliding fit. In the initial state, the connecting rod 18 is located between one end of the two limiting plates 19 and the heat-absorbing film 15 is pulled out to cover the outer surface of the storage tank 2. A magnetic block 20 is bonded between each pair of vertically aligned limiting plates 19. The magnetic block 20 is magnetically attracted to the corresponding connecting rod 18, thereby firmly fixing the heat-absorbing film 15 after it is pulled out, preventing it from shifting due to wind or other external forces, and ensuring that the heat-absorbing film 15 always stably covers the outer surface of the storage tank 2 to achieve the best heat absorption effect.

[0027] like Figures 4-7 As shown, it also includes a connecting cover 16 and a spiral spring 17. A connecting cover 16 is welded to both the upper and lower ends of each support shaft 14. Each spiral spring 17 is located inside each connecting cover 16, and its two ends are fixedly connected to the corresponding connecting cover 16 and the corresponding support shaft 14 respectively. The elastic force of the spiral spring 17 can realize the automatic winding function of the heat absorption film 15.

[0028] In the initial state, the heat-absorbing film 15 is pulled out from the support shaft 14 and covers the outer surface of the liquid storage tank 2. At this time, the spiral spring 17 is in a deformed state in preparation for subsequent automatic winding.

[0029] When this device is needed, the user first installs the support base 1 on the roof or other suitable location to receive sunlight, ensuring that the liquid storage tank 2 is oriented in a reasonable way to obtain the maximum light area. Then, the external pipes are passed through the square slot on the support base 1 in sequence and connected to the two connecting valves 201. An appropriate amount of heat transfer liquid is injected into the liquid storage tank 2 through the left connecting valve 201 to prepare for subsequent heat collection and heating.

[0030] After injection, start the servo motor 10 and control its output shaft to drive the worm gear 11 to rotate clockwise or counterclockwise, so that the worm gear 11 and the corresponding worm wheel 12 can mesh and transmit in the forward or reverse direction. Driven by the worm gear 11, the worm wheel 12 rotates accordingly and drives the connecting shaft 9 to rotate synchronously, thereby driving the reflector 8 to rotate inward or outward around the axis to adjust to the optimal reflection angle. After adjustment, turn off the servo motor 10.

[0031] During daytime operation, sunlight first penetrates the lens 4, and after refraction and focusing, it shines into the heat transfer liquid inside the storage tank 2, thereby directly increasing the liquid temperature. At the same time, external light enters the connecting ring 5 and is captured by the refracting mirror 6. The refracting mirror 6 concentrates and guides the incident light onto the lens 4, further enhancing the collection efficiency and focusing effect of sunlight, and achieving multi-level light-gathering effect.

[0032] At the same time, the reflector 8 reflects more sunlight to the outer surface of the liquid storage tank 2, expands the heating area and increases its surface temperature, achieves all-weather high-efficiency light concentration, and further improves the overall heat collection efficiency;

[0033] In addition, the heat-absorbing film 15 covering the outside of the liquid storage tank 2 efficiently absorbs solar energy and converts it into heat energy, which is then conducted to the surface of the liquid storage tank 2, thereby assisting in heating the internal heat transfer liquid, expanding the effective heat absorption area of ​​the liquid storage tank 2, and improving the overall system heat conversion efficiency.

[0034] When the heat-absorbing film 15 is not needed (such as at night or on a cloudy day), manually release the adsorption state between the connecting rod 18 and the magnetic block 20. At this time, the spiral spring 17 returns to its original state, drives the support shaft 14 to rotate, and rewinds the heat-absorbing film 15 onto the support shaft 14, so as to avoid the heat-absorbing film 15 being exposed to the outside for a long time and reduce unnecessary heat loss.
