[0045] The technical means, creation features, purposes and effects of the present application are described below in conjunction with specific embodiments.

[0046] As shown in the accompanying drawings Figure 1 to the accompanying Figure 11 The present application provides a solar heat collecting and heating device with adjustable inclination, comprising a mounting plate 1; a heat collector 2 fixedly installed on the top of the mounting plate 1 for absorbing solar radiation energy and heating air into hot air, the heat collector 2 comprises a heat collecting pipe array composed of a plurality of parallel vacuum heat collecting pipes, which effectively reduces heat loss by utilizing the high vacuum degree characteristics of the vacuum heat collecting pipe; when solar radiation irradiates on the heat collecting pipe, the heat absorbing coating inside the heat collecting pipe absorbs solar radiation energy, converts light energy into heat energy, and heats the air inside the pipe; a plurality of parallel vacuum heat collecting pipes are used to form a heat collecting pipe array, which increases the heat collecting area and improves the heat collecting efficiency; the parallel structure makes each heat collecting pipe independent of each other, so that even if an individual heat collecting pipe fails, it does not affect the normal operation of the entire heat collector 2; a cleaning mechanism 3 is arranged above the mounting plate 1 and acts on the heat collecting pipe of the heat collector 2 for removing dust attached to the surface of the heat collecting pipe; an adjusting mechanism 5 is arranged on the first base 4, the adjusting mechanism 5 comprises a first adjusting assembly 501 for adjusting the azimuth angle of the heat collector 2 and a second adjusting assembly 502 for adjusting the inclination angle of the heat collector 2, the second adjusting assembly 502 is installed on the first adjusting assembly 501, the first base 4 is arranged below the mounting plate 1, and the outer side of the first base 4 is connected with a second base 6 through an extension plate; an energy storage barrel 7 is arranged on the rear side of the heat collector 2 and installed on the second base 6, the energy storage barrel 7 is used to store the heat transferred by the hot air heated by the heat collector 2, the inner wall of the energy storage barrel 7 is made of graphene reinforced aluminum alloy,

[0047] As Figures 3-6As shown, in one embodiment of the present application, the first adjusting assembly 501 comprises a track body 5011, a track groove 5012, a sliding piece 5013, a bearing plate 5014, a second driving piece 5015, a fixing sleeve 5016 and a connecting rod 5017, which are arranged on the first base 4. The track body 5011 is provided with the annular track groove 5012 on the side, the sliding piece 5013 slides on the track groove 5012, and four groups of the sliding pieces 5013 are distributed on the front and back of the track body 5011. The top of the two groups of the sliding pieces 5013 on the front side is hinged to the lower surface of the mounting plate 1. The inner side of the middle part of the track body 5011 is fixedly provided with the second driving piece 5015 through the bearing plate 5014. The output end of the second driving piece 5015 is sleeved with the fixing sleeve 5016. The outer circumferential surface of the fixing sleeve 5016 is distributed with four connecting rods 5017. The other ends of the four connecting rods 5017 are respectively connected with the side of the four groups of the sliding pieces 5013. Specifically, when the second driving piece 5015 is started, the output end drives the fixing sleeve 5016 to rotate. Since the outer circumferential surface of the fixing sleeve 5016 is distributed with the four connecting rods 5017, and the other ends of the four connecting rods 5017 are respectively connected with the side of the four groups of the sliding pieces 5013, the rotation of the fixing sleeve 5016 will drive the sliding pieces 5013 to slide on the annular track groove 5012 on the side of the track body 5011 through the connecting rods 5017. With the sliding of the sliding pieces 5013 on the track groove 5012, the mounting plate 1 will be driven to rotate around a certain axis, so as to realize the adjustment of the azimuth angle of the collector 2.

[0048] In one embodiment of the present application, the second adjusting assembly 502 comprises a support rod 5021, a foot plate 5022, a movable shaft 5023, an inclination rod 5024, a fixing block 5025, a connecting frame 5026, a hoop 5027, a telescopic rod 5028 and a connecting piece 5029, which are arranged on the top of the two groups of the sliding pieces 5013 on the back side. The bottom of the support rod 5021 is provided with the foot plate 5022 which is fixedly connected with the sliding piece 5013. The top of the support rod 5021 is rotatably connected with the inclination rod 5024 through the movable shaft 5023. The two ends of the inclination rod 5024 are fixedly arranged on the bottom of the mounting plate 1 through the fixing block 5025. The support rod 5021 is provided with the hoop 5027 on one side of the top through the connecting frame 5026. The hoop 5027 is internally provided with the telescopic rod 5028. The output end of the telescopic rod 5028 is fixedly connected with the connecting piece 5029 arranged on the bottom of the outer surface of the inclination rod 5024. Specifically, when the telescopic rod 5028 is telescoped, the output end drives the inclination rod 5024 to rotate around the movable shaft 5023 through the connecting piece 5029. Since the inclination rod 5024 is fixedly connected with the mounting plate 1, the rotation of the inclination rod 5024 will drive the mounting plate 1 to incline, so as to change the inclination angle of the collector 2. Thus, the collector 2 can be adjusted to the appropriate inclination angle according to the change of the altitude angle of the sun in different seasons and time, so as to obtain the maximum solar radiation absorption.

[0049] In addition, a light intensity sensor is installed on the front side of the mounting plate 1 to sense the light intensity, thereby controlling the second drive component 5015 and the telescopic rod 5028 to adjust the solar collector 2 in real time.

[0050] The first adjustment component 501 should adjust the azimuth angle before the collector 2 is connected to the heating device via pipeline.

[0051] like Figures 9-11 As shown, in one embodiment of the present invention, the cleaning mechanism 3 includes a base plate 301. Two sets of base plates 301 are provided and distributed on the front and rear sides of the top of the mounting plate 1. Several corresponding first ear seats 302 are evenly distributed on both sides of the base plate 301 along the plate body direction. A lead screw 303 is provided between the first ear seats 302 on the outer side of both sides of the base plate 301. A guide rod 304 is installed between the remaining first ear seats 302 on both sides of the base plate 301. A moving part 305 is connected to the outside of both lead screws 303. A sliding sleeve 306 is correspondingly connected to the outside of the guide rod 304. The top of the moving part 305 and the sliding sleeve 306 are connected to the cleaning plate 307.

[0052] In one embodiment of the present invention, the cleaning mechanism 3 further includes second ear seats 308 disposed on both sides of the cleaning plate 307. An adjusting rod 309 is installed between the two second ear seats 308. The adjusting rod 309 has a plurality of opposing threaded grooves 310 corresponding to the heat collection tube array. Each of the plurality of opposing threaded grooves 310 has opposing threaded blocks 311. The top of the two threaded blocks 311 is provided with opposing fixing rods 312. The end of the fixing rod 312 is provided with a cleaning brush 314 acting on the surface of the heat collection tube through a connecting block 313. By rotating the adjusting rod 309, since the adjusting rod 309 has opposing threaded grooves 310, the opposing threaded blocks 311 move towards each other along the adjusting rod 309 under the action of the threads, thereby driving the fixing rod 312 and the cleaning brush 314 to move, thereby adjusting the spacing of the cleaning brush 314 and ensuring that the cleaning brush 314 can fit tightly against the surface of the heat collection tube and effectively remove dust.

[0053] In one embodiment of the present invention, the adjusting rod 309 forms an annular closed cleaning brush 314 via an adjusting knob 315 located on its outer side. The annular closed cleaning brush 314 structure allows the cleaning brush 314 to form a continuous cleaning area around the heat collector tube, avoiding dead corners during the cleaning process. During cleaning, the cleaning brush 314 can wipe the surface of the heat collector tube from all directions, ensuring that dust and dirt on the surface of the heat collector tube are thoroughly removed, thereby improving the photothermal conversion efficiency of the heat collector 2.

[0054] In one embodiment of the present application, the end of one side screw rod 303 is fixedly connected with the output end of the first driving member 316 arranged on the top of the mounting plate 1, and the output end of the first driving member 316 drives the other side screw rod 303 through the synchronous member 317.

[0055] Specifically, when it is needed to adjust the interval of the cleaning brushes 314 to ensure that the cleaning brushes 314 closely fit the surface of the heat collecting pipes, the operator rotates the adjusting knob 315 arranged outside the adjusting rod 309, and the adjusting knob 315 drives the adjusting rod 309 to rotate about its axis. Since a plurality of groups of opposite threaded grooves 310 corresponding to the heat collecting pipe array are distributed on the adjusting rod 309, when the adjusting rod 309 rotates, the oppositely arranged threaded blocks 311 move towards each other along the adjusting rod 309 under the action of the threads. The movement of the threaded blocks 311 drives the fixed rod 312 to move, and the end of the fixed rod 312 is provided with the cleaning brushes 314 through the connecting block 313. Therefore, the cleaning brushes 314 also move, so that the interval of the cleaning brushes 314 is adjusted, and it is ensured that the cleaning brushes 314 can closely fit the surface of heat collecting pipes of different specifications. When it is needed to clean the surface of the heat collecting pipes, the first driving member 316 arranged on the top of the mounting plate 1 is started, the output end of the first driving member 316 starts to rotate, and the output end of the first driving member 316 drives the other side screw rod 303 through the synchronous member 317 arranged thereon, so that the two screw rods 303 rotate at the same speed and in the same direction. When the screw rod 303 rotates, the moving member 305 moves linearly along the screw rod 303. At the same time, the guide rods 304 arranged between the remaining first ear seats 302 of the two base plates 301 and the sliding sleeves 306 connected to the outside of the guide rods 304 correspondingly play the role of guiding and supporting, so that the moving member 305 can move linearly stably and accurately. With the linear movement of the moving member 305, the cleaning plate 307 also moves, and in turn drives the cleaning brushes 314 to move linearly and reciprocally on the surface of the heat collecting pipes, so that the surface of the heat collecting pipes is cleaned comprehensively.

[0056] Among them, it needs to be further described that a rubber pad is arranged between the connecting block 313 and the cleaning brush 314, which can play a buffering role when the cleaning brush 314 contacts the surface of the heat collecting pipe.

[0057] The first driving member 316 and the second driving member 5015 both adopt a motor of model Rexas 57CM series.

[0058] As Figures 7-8As shown, in one embodiment of the present application, the energy storage barrel 7 is divided into an upper water injection area 701, a middle heat exchange area 703 and a lower water storage area 702. The upper side wall of the heat exchange area 703 is provided with an air flow pipe 704 for discharging low-temperature air after heat exchange, and the lower side wall of the heat exchange area 703 is provided with an air outlet pipe 705 for guiding hot air heated by the heat collector 2 into the heat exchange area 703. The top of the water injection area 701 is provided with a water injection pipe 706 for supplementing cold water into the energy storage barrel 7. The side wall of the water storage area 702 is provided with a water delivery pipe 707, and the side wall of the water injection area 701 is correspondingly provided with a return pipe 708 with respect to the water delivery pipe 707. The water delivery pipe 707 is connected to the water inlet end of the circulating pipeline of the indoor heating element 9, and the return pipe 708 is connected to the water return end of the circulating pipeline of the indoor heating element 9, forming a closed circulation loop.

[0059] In one embodiment of the present application, the inner cavity of the heat exchange area 703 is provided with oppositely distributed flow guide plates 7032 through positioning rods 7031 for guiding the flow of hot air. The heat exchange area 703 is provided with a straight pipe array of water flow pipes 7033. The upper and lower pipe ends of the water flow pipes 7033 are respectively connected to the upper and lower water injection areas 701 and the water storage area 702.

[0060] In one embodiment of the present application, the air flow pipe 704 is integrated with a fan 8 near the air inlet of the heat collector 2.

[0061] Specifically, the collector 2 absorbs solar energy under sunlight and converts it into heat energy, and heats the air flowing through the inside of the collector 2. The high-temperature hot air after heating is introduced into the middle heat exchange area 703 of the energy storage barrel 7 through the air outlet pipe 705, and when the hot air enters the heat exchange area 703, the hot air flows in a baffle shape under the guidance of the flow guide plate 7032, greatly increasing the residence time and flow path of the hot air in the heat exchange area 703. When the hot air flows in a baffle shape in the heat exchange area 703, water is injected into the water injection area 701 through the water injection pipe 706, and the water in the water injection area 701 flows into the water flow pipe 7033 connected with the water injection area 701 under the action of its own gravity. The water flow pipe 7033 is arranged in the heat exchange area 703 in the form of a straight pipe array. The hot air in the baffle flow process will be in contact with the outer wall of the water flow pipe 7033 in all directions, and the hot air will transfer heat to the water in the water flow pipe 7033, so that the temperature of the water is increased, and the temperature of the hot air itself is reduced, becoming low-temperature air. The low-temperature air after heat exchange is discharged through the air flow pipe 704 arranged on the upper side wall of the heat exchange area 703. The air flow pipe 704 is integrated with the fan 8 near the air inlet of the collector 2. After the fan 8 is started, a negative pressure can be formed in the system to accelerate the flow of air, which not only helps to quickly discharge the low-temperature air after heat exchange, but also promotes the air in the collector 2 to flow into the heat exchange area 703 faster, ensuring the continuous and stable progress of the entire heat exchange process. When the water in the energy storage barrel 7 is heated in the heat exchange area 703, the hot water will flow into the circulating pipeline of the indoor heating element 9 through the water delivery pipe 707. The hot water in the heating element 9 will release heat to the indoor air during the flow process, achieving heating for the indoor. The low-temperature water after heat dissipation flows back to the water injection area 701 of the energy storage barrel 7 through the return pipe 708, and participates in the heat exchange process again, so as to continuously provide heat for the indoor.

[0062] Further, because the pipe end of the water flow pipe 7033 is connected to the lower water storage area 702, the heated water will flow into the water storage area 702 along the pipe, and these hot water obtained by heat exchange will be stored properly. When heating is needed for the indoor, the hot water stored in the water storage area 702 will flow into the circulating pipeline of the indoor heating element 9 through the water delivery pipe 707, and the low-temperature water after heat dissipation will flow back to the water injection area 701 of the energy storage barrel 7 through the return pipe 708, and participate in the heat exchange process again.

[0063] In use, first, fix the collector 2 into the preset positioning groove on the top of the mounting plate 1 through the bottom flange, ensuring that the axis of the collector tube array is parallel to the long side of the mounting plate 1. Then, align the two sets of hinge points on the front side of the lower surface of the mounting plate 1 with the top hinge seats of the two sets of sliding parts 5013 on the front side of the first adjustment assembly 501 and tighten the bolts to complete the installation of one side of the collector 2. Then, connect and fix the other side of the collector 2 to the fixing block 5025. After the collector 2 is installed on the adjustment mechanism 5, adjust its orientation through the first adjustment assembly 501. After adjustment, the pipeline connection work is then carried out.
