Description

Technical Field

[0001] This invention belongs to the field of energy storage device technology, and specifically relates to a solar thermal energy storage device. Background Technology

[0002] With the increasing prominence of energy issues, the demand for energy-saving storage devices is constantly growing. Currently, most common energy storage devices are single-function batteries with limited capabilities.

[0003] For some energy storage devices that combine solar energy utilization, there are many inconveniences in their installation and maintenance. When it is necessary to maintain components such as collector tubes or solar panels, the operation is relatively cumbersome, often requiring complex outdoor work, and it is not easy to bring the relevant components indoors. This not only increases the difficulty of maintenance, but may also be affected by factors such as weather, reducing the reliability and service life of the device.

[0004] In addition, the existing equipment needs to be improved in terms of energy utilization flexibility. It is not able to switch reasonably according to the demand for power generation and hot water supply in different seasons, resulting in low overall energy utilization efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a solar thermal energy storage device. This energy storage device aims to solve the problems of inconvenient installation and maintenance, inflexible energy utilization, and inability to achieve mechanical linkage control of heating valves in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A solar thermal energy storage device includes an energy storage battery, a water storage tank, a mounting frame, and a support frame. A support shaft is rotatably connected to the mounting frame, and the support frame is slidably connected to the support shaft. A fixed frame is fixedly connected to the mounting frame, and a fixed groove is provided on the support frame. A fixed slider that engages with the fixed frame is slidably connected in the fixed groove, and a drive rod that drives the fixed slider to move is provided on the support frame.

[0008] An output pipe is fixed on the support frame, and several heat collection pipes are connected to the output pipe. Several support sleeves that cooperate with the heat collection pipes are rotatably connected to the support frame. Each heat collection pipe extends through the corresponding support sleeve and is connected to an input pipe. Both the input pipe and the output pipe are connected to the heat exchange pipe in the water storage tank. The water storage tank is equipped with a heating pipe, and a heating valve is installed on the heating pipe. The heating valve is connected to an opening and closing component.

[0009] Each solar collector tube is rotatably connected to a solar panel, and each solar panel is fixedly connected to a corresponding support sleeve. Each solar panel is connected to an energy storage battery via a circuit. The mounting frame is equipped with a control mechanism to control the rotation of the solar panels, so that the solar panels face up or down. When all solar panels face down, the opening and closing component controls the heating valve to open.

[0010] The driving rod is a driving screw, which is rotatably connected to the support frame, and the fixed slider is threadedly connected to the driving screw; the support frame is provided with two fixed grooves, and a fixed slider is slidably connected in each of the two fixed grooves.

[0011] The control mechanism includes a control handle, a transmission assembly, a first rack, and a second rack. The first rack and the second rack are spaced apart and are both slidably connected to the support frame. A portion of the support sleeves is fixed with a first gear meshing with the first rack, and the remaining support sleeves are fixed with a second gear meshing with the second rack. The control handle drives the first rack and / or the second rack to move through the transmission assembly. A first return spring is provided between the first rack and the second rack and the support frame. Limiting protrusions are provided on both the first rack and the second rack, and corresponding limiting plates are provided on the support frame.

[0012] The transmission assembly includes a transmission plate, a shift fork plate, and a cam; a support base is fixedly connected to the support frame, and a rotating shaft that is rotatably connected to the support base is fixedly connected to the control handle; the cam is fixedly connected to the rotating shaft.

[0013] The transmission plate is slidably connected to the support frame, and the outer surface of the cam contacts the side of the transmission plate; the shift fork is slidably connected to the transmission plate, and a fixing component is provided between the shift fork and the transmission plate; a connecting post is fixedly connected to one end of both the first rack and the second rack; a connecting groove that mates with the connecting post is provided at both the upper and lower ends of the shift fork.

[0014] The fixing component includes a fixing stud and a fixing nut. The transmission plate is provided with a guide groove. The end of the fixing stud passes through the guide groove and is fixedly connected to the shift fork plate. The fixing nut is threadedly connected to the fixing stud.

[0015] A limit pin is provided between the control handle and the support base.

[0016] The opening and closing assembly includes a base box, an opening and closing rack, and an opening and closing gear. The base box is fixedly connected to the support frame. The valve body of the heating valve is fixedly connected to the base box. The opening and closing gear is coaxially fixedly connected to the valve stem of the heating valve. The opening and closing rack is slidably connected to the base box and meshes with the opening and closing gear. A second return spring is provided between the opening and closing rack and the base box. A push plate is provided at one end of the opening and closing rack. Push columns are fixedly connected to the other ends of the first rack and the second rack. After the two push columns contact the push plate, they push the opening and closing rack to move.

[0017] The push plate is slidably connected to the opening and closing rack, and a third reset spring is provided between the push plate and the opening and closing rack; guide slopes are provided on both the upper and lower sides of the push plate.

[0018] Compared with the prior art, the beneficial effects of this invention are:

[0019] The device utilizes a connection structure between a drive rod and a fixed slider, which allows the support frame to be flexibly switched between different states. During maintenance, the support frame can be pulled indoors, facilitating the maintenance of the heat collection tubes and solar panels, reducing maintenance difficulty, and avoiding damage to the device from severe outdoor weather, thus extending its service life.

[0020] By controlling the rotation of the solar panels through a control mechanism, the system can switch between power generation in summer and hot water supply in winter. When all solar panels are facing down, the heating valves are automatically opened to provide heating, thus optimizing the overall energy utilization rate. This allows the device to flexibly adjust energy output according to seasonal changes and actual needs, better meeting the diverse energy needs of users.

[0021] The design of the opening and closing assembly enables mechanical linkage control of the heating valve's opening and closing. When the first and second racks move to make all the solar panels face downwards, the push column contacts the push plate, pushing the opening and closing racks to move, causing the heating valve to open and provide heating. When the first and second racks return to their original positions, the second return spring releases its elastic potential energy, causing the opening and closing racks to move in the opposite direction, closing the heating valve. This structure ensures that the opening and closing state of the heating valve matches the orientation of the solar panels and improves the reliability of the device's operation.

Detailed Implementation

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] like Figures 1 to 4 As shown, a solar thermal energy storage device includes an energy storage battery 1, a water storage tank 2, a mounting frame 3, and a support frame 4. A support shaft 5 is rotatably connected to the mounting frame 3, and the support frame 4 is slidably connected to the support shaft 5. During installation, the mounting frame 3 is fixed to the wall of the building.

[0035] A fixing frame 6 is fixedly connected to the mounting frame 3. The fixing frame 6 can be fixedly connected to the mounting frame 3 by welding or bolts. The support frame 4 is provided with a fixing groove 7. A fixing slider 8 that is engaged with the fixing frame 6 is slidably connected in the fixing groove 7. The fixing frame 6 is provided with a corresponding slot. The support frame 4 is provided with a drive rod 9 that drives the fixing slider 8 to move.

[0036] In use, after extending the support frame 4 outdoors, push the support frame 4 to rotate so that the fixing frame 6 extends into the fixing groove 7; then drive the fixing slider 8 to move through the drive rod 9, so that the fixing slider 8 moves and engages with the fixing frame 6, and the fixing frame 6 contacts the inner wall of the fixing groove 7, thereby fixing the position of the support frame 4.

[0037] In the maintenance state, drive the fixed slider 8 to move in the opposite direction via the drive rod 9, so that the fixed slider 8 moves and separates from the fixed frame 6; push the support frame 4 to rotate in the opposite direction so that the fixed frame 6 moves out of the fixed groove 7; finally, pull the support frame 4 into the room for maintenance.

[0038] With the above-described structure, not only can the support frame 4 be easily pulled indoors for maintenance, but it can also be fixed indoors. Furthermore, due to the structure of the support shaft 5 and the fixing frame 6, the tilt angle of the support frame 4 can be changed. Specifically, depending on the installation location, the fixing frame 6 can be fixed to the mounting frame 3 at an appropriate height; and by changing the height of the fixing frame 6, the tilt angle of the support frame 4 can be altered.

[0039] An output pipe 10 is fixed on a support frame 4, and several heat collection pipes 11 are connected to the output pipe 10. Several support sleeves 12 that cooperate with the heat collection pipes 11 are rotatably connected to the support frame 4. Each heat collection pipe 11 extends through the corresponding support sleeve 12 and is connected to an input pipe 13. Both the input pipe 13 and the output pipe 10 are connected to the heat exchange pipe 14 in the water storage tank 2, thus forming a circulation. When the liquid in the heat collection pipe 11 absorbs solar radiation and heats up, it heats the water in the water storage tank 2. A heating pipe 15 is provided on the water storage tank 2, and a heating valve 17 is provided on the heating pipe 15. The heating valve 17 is connected to an opening and closing component 18. The heating pipe 15 is connected to a radiator 16, and the radiator 16 is connected to the water storage tank 2 through a return pipe to form a circulation. When the heating valve 17 is opened, the hot water in the water storage tank 2 enters the radiator 16 through the heating valve 17 and dissipates heat through the radiator 16.

[0040] A solar panel 19 is rotatably connected to each heat collector tube 11, and each solar panel 19 is fixedly connected to a corresponding support sleeve 12. Specifically, the solar panels 19 are connected in series or parallel, and then connected to the energy storage battery 1 through wiring and a controller 190. A control mechanism 20 is provided on the mounting frame 3 to control the rotation of the solar panels 19, so that the solar panels 19 face upwards or downwards. When the solar panel 19 faces upwards, it will block the corresponding heat collector tube 11, and the sun will shine on the solar panel 19 to generate electricity; conversely, when the solar panel 19 faces downwards, the sun will shine on the heat collector tube 11, causing the liquid inside the heat collector tube 11 to be heated.

[0041] During the summer, the system primarily generates electricity, with hot water as a secondary function; this is achieved by controlling mechanism 20 to ensure that some or all of the solar panels 19 face upwards. At this time, heating valve 17 is closed and no heating is provided.

[0042] In winter, hot water is the primary source of heating, with power generation as a secondary function (or no power generation at all); that is, the control mechanism 20 directs some or all of the solar panels 19 downwards. When all the solar panels 19 are downwards, the opening and closing component 18 controls the heating valve 17 to open and provide heating.

[0043] Since the heat collection tube 11 and the solar panel 19 require regular maintenance, the above-mentioned structural design allows the support frame 4 to be easily pulled indoors for inspection.

[0044] Furthermore, such as Figure 3 As shown, the aforementioned drive rod 9 is a drive screw, which is rotatably connected to the support frame 4, and the fixed slider 8 is threadedly connected to the drive screw. An internal hexagonal groove is provided at the end of the drive screw, allowing it to be rotated using an internal hexagonal wrench; when the drive screw rotates, it can drive the fixed slider 8 to move.

[0045] The support frame 4 has two fixing grooves 7, and a fixing slider 8 is slidably connected in each of the two fixing grooves 7. In use, the fixing frame 6 is connected to the fixing slider 8 in the fixing groove located on the rear side. In windy weather, the fixing frame 6 is connected to the fixing slider 8 in the fixing groove located on the front side, which can reduce the exposed length of the support frame 4 and prevent it from being damaged.

[0046] Furthermore, such as Figures 4 to 7 As shown, the control mechanism 20 includes a control handle 200, a transmission assembly 201, a first rack 202, and a second rack 203. The first rack 202 and the second rack 203 are spaced apart and both are slidably connected to the support frame 4. A portion of the several support sleeves 12 has a first gear 204 fixed on it, meshing with the first rack 202; the remaining support sleeves 12 have second gears 205 fixed on them, meshing with the second rack 203. Specifically, the first gear 204 and the second gear 205 are staggered (e.g., ...). Figure 4 (As shown).

[0047] The control handle 200 drives the first rack 202 or the second rack 203 to move via the transmission assembly 201, or it can drive the first rack 202 and the second rack 203 to move together. When the first rack 202 moves, it drives the corresponding support sleeve 12 and the solar panel 19 to rotate by meshing with the first gear 204; when the second rack 203 moves, it drives the corresponding support sleeve 12 and the solar panel 19 to rotate by meshing with the second gear 205.

[0048] A first return spring 208 is provided between the first rack 202 and the second rack 203 and the support frame 4. When the first rack 202 or the second rack 203 moves, the corresponding first return spring 208 can generate elastic potential energy. The first return spring 208 is specifically a tension spring. A limiting protrusion 206 is provided on the first rack 202 and the second rack 203, and a corresponding limiting plate 207 is provided on the support frame 4. When the first return spring 208 releases its elastic potential energy, it drives the corresponding first rack 202 or the second rack 203 to return to its original position, so that the limiting protrusion 206 abuts against the limiting plate 207.

[0049] The transmission assembly 201 includes a transmission plate 2010, a shift fork 2011, and a cam 2012. A support base 2018 is fixedly connected to the support frame 4. A rotating shaft 2013, rotatably connected to the support base 2018, is fixed to the control handle 200. The cam 2012 is fixedly connected to the rotating shaft 2013. The transmission plate 2010 is slidably connected to the support frame 4. The outer surface of the cam 2012 contacts the side of the transmission plate 2010. Rotating the control handle 200 drives the cam 2012 to rotate, which in turn pushes the transmission plate 2010 to move. The shift fork 2011 is slidably connected to the transmission plate 2010. A fixing component 209 is provided between the shift fork 2011 and the transmission plate 2010, which can fix the position of the shift fork 2011.

[0050] When the highest point of the cam 2012 contacts the transmission plate 2010, the transmission plate 2010 will drive the first rack 202 or the second rack 203 to move to the farthest distance, causing the solar panel 19 to rotate downwards. When the lowest point of the cam 2012 contacts the transmission plate 2010, the first return spring 208 releases its elastic potential energy, causing the corresponding first rack 202 or the second rack 203 to return to its original position, causing the solar panel 19 to rotate upwards.

[0051] A connecting post 2014 is fixedly connected to one end of both the first rack 202 and the second rack 203; both the upper and lower ends of the shift fork plate 2011 are provided with connecting grooves 2015 that mate with the connecting posts 2014. When it is only necessary to drive the first rack 202 to move so that part of the solar panel 19 can rotate, the shift fork plate 2011 needs to be pushed upward so that the connecting groove 2015 at the upper end of the shift fork plate 2011 engages with the connecting post 2014 on the first rack 202, and the connecting groove 2015 at the lower end of the shift fork plate 2011 separates from the connecting post 2014 on the second rack 203. Then, the position of the shift fork plate 2011 is fixed by the fixing component 209. At this time, turning the control handle 200 will only move the first rack 202.

[0052] When it is necessary to drive all solar panels 19 to rotate, the shift fork lever is positioned in the center (the position of the shift fork plate 2011 is fixed by the fixing component 209), and the connecting slots 2015 at both ends of the shift fork plate 2011 are inserted into the connecting posts 2014 on the first rack 202 and the second rack 203. At this time, rotating the control handle 200 will cause the first rack 202 and the second rack 203 to move together.

[0053] Furthermore, such as Figure 6 As shown, the fixing assembly 209 includes a fixing stud 2090 and a fixing nut 2091. The transmission plate 2010 has a guide groove 2016. The end of the fixing stud 2090 passes through the guide groove 2016 and is fixedly connected to the shift fork plate 2011. The fixing nut 2091 is threadedly connected to the fixing stud 2090. Pushing the fixing stud 2090 will move the shift fork plate 2011. After movement, tightening the fixing nut 2091 will press it against the transmission plate 2010, thereby fixing the position of the shift fork plate 2011.

[0054] To prevent the control handle 200 from rotating arbitrarily, a limit pin 2017 is provided between the control handle 200 and the support base 2018; both the control handle 200 and the support base 2018 are provided with corresponding pin holes.

[0055] Furthermore, such as Figure 9 and Figure 10 As shown, the opening and closing assembly 18 includes a base box 180, an opening and closing rack 181, and an opening and closing gear 182. The base box 180 is fixedly connected to the support frame 4. The valve body of the heating valve 17 is fixedly connected to the base box 180. The opening and closing gear 182 is coaxially fixedly connected to the valve stem of the heating valve 17. The opening and closing rack 181 is slidably connected to the base box 180 and meshes with the opening and closing gear 182. A second return spring 183 is provided between the opening and closing rack 181 and the base box 180. The second return spring 183 is a tension spring, and its two ends are fixedly connected to the opening and closing rack 181 and the base box 180, respectively.

[0056] When the opening / closing rack 181 moves, it meshes with the opening / closing gear 182 and drives the valve stem to rotate (the second return spring 183 generates elastic potential energy), thus opening the heating valve 17. When the first rack 202 and the second rack 203 return to their original positions, the elastic potential energy is released through the second return spring 183, which pushes the opening / closing rack 181 to move in the opposite direction, meshes with the opening / closing gear 182, and drives the valve stem to rotate in the opposite direction, thus closing the heating valve 17.

[0057] A push plate 184 is provided at one end of the opening and closing rack 181, and a push column 185 is fixedly connected to the other end of the first rack 202 and the second rack 203. Only when the first rack 202 and the second rack 203 move (so that all solar panels 19 face down) and the two push columns 185 come into contact with the push plate 184 together can the opening and closing rack 181 be pushed to move, so that the heating valve 17 can be opened to provide heating.

[0058] The push plate 184 is slidably connected to the opening and closing rack 181, and a corresponding groove is provided on one side of the opening and closing rack 181; a baffle 188 is provided in the middle of the groove. A third return spring 186 is provided between the push plate 184 and the baffle 188 of the opening and closing rack 181; guide slopes 187 are provided on both the upper and lower sides of the push plate 184. Specifically, there are two third return springs 186, and the upper and lower ends of the two third return springs 186 are in contact with the push plate 184 and the baffle 188, respectively.

[0059] Because the stiffness coefficient of the second return spring 183 is greater than that of the third return spring 186, the second return spring 183 is "stiffer". Therefore, when only the first rack 202 moves, the push post 185 on the first rack 202 contacts the guide slope 187 on one side of the upper end of the push plate 184, and pushes the push plate 184 downward, then "passes over" the push plate 184; when the first rack 202 returns to its original position, the push post 185 on the first rack 202 contacts the guide slope 187 on the other side of the upper end of the push plate 184, and pushes the push plate 184 downward, then "passes over" the push plate 184 again. Conversely, when the first rack 202 and the second rack 203 move together, the two push posts 185 will simultaneously contact the upper and lower ends of the push plate 184, thereby pushing the push plate 184 and the opening / closing rack 181 to move.
