Sunlight passes through the outer shell and shines on the heat-absorbing layer of the inner shell, absorbing the heat of solar energy.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, by setting a heat exchange component, when the heat absorption panel is a flexible stacked wavy heat exchange film, the flexible film can adjust the expansion area under the action of driving the heat collection flexible shells on both sides to extend outwards through the front end adjustment mechanism, and then can pull the internally connected heat absorption component to adjust the expansion, which is beneficial to adjusting the heat exchange efficiency of the internal heat exchange medium through the expansion of the top contact area, and the heat exchange inner capsule absorbs the heat into the heat collection drainage ring, and the multiple abutment plates inside the drainage ring can bear the impact of the medium, and the terminal medium is effectively received and dispersed through the drainage ring, and then the heat of the solar flat plate under the action of flexibility is realized through the cooperation of the heat absorption panel and the heat exchange inner capsule, which can adapt to the assembly needs of different installation positions, and at the same time, the contact heat exchange area can be effectively increased through the fitting surfaces of the wavy structures on both sides, and the relative heat collection capacity can be obtained by adjusting the expansion area of ​​the heat absorption panel, which can adapt to the heat exchange needs under different flow rates and pressures, meet high installation adaptability and plastic support capacity, and improve overall safety and durability.

[0028] 2. In the present invention, through the support assembly, when the pressure of the heat exchange medium is too large, the motor output shaft rotates to drive the active gear to pull the driven rack and the connecting block to move. The movement of the connecting block can drive the driving rod to pull the end support cross bar to move, drive multiple hinged seats to rotate relative to the hinge and pull the front sliding seat to move. The movement of the sliding seat can drive the relative lateral position of the support ribs on one side. The movement of the support ribs can realize the lateral pulling of the top-fitting heat exchange inner capsule corrugated cavity to change its inclination angle through the top wavy structure. The wavy inner cavity at the bottom of the heat exchange inner capsule is pulled to limit the adjustment of the inclination angle and has corresponding support stress. The fitting and pulling of multiple support ribs can effectively improve the impact absorption capacity of the internal medium flow, improve the stability of the flexible heat exchange inner capsule under the flow of the medium, effectively resist partial external impact, and improve the durability.

[0029] 3. In the present invention, through the designed sliding seat, the sliding seat can move upward outside the hinged seat shaft when being pulled through the cooperation of the inclined surface of the bottom triangular plate, thereby driving the sliding seat to pull one side support rib plate upward and squeeze the first spring outside the shaft body at the same time. The movement of the support rib plate can effectively improve the longitudinal support for the bottom of the top heat exchange inner capsule, which is beneficial to achieve enhanced stability. At the same time, the offset force can be transmitted to the surface of the energy absorbing plate through the abutment with the energy absorbing plate on one side. The energy absorbing plate can absorb the corresponding offset force by sliding outside the fixed rod, thereby improving the fitting and limiting support capacity of the adjacent energy absorbing plates to the heat exchange inner capsule, improving the stability and safety of the bottom support of the heat exchange inner capsule, avoiding impact-induced frequency vibration of the heat exchange inner capsule and affecting the durability. At the same time, the energy absorbing plate can utilize the self-heat exchange material to absorb the corresponding heat storage capacity, ensure the relative temperature inside the heat collection flexible shell, and improve the heat collection treatment effect.

[0030] 4. In the present invention, the main body of the water tank can initially filter impurities in the feeding medium through the cooperation of the water tank feeding seat on one side and the active filter screen, and the flexible sheath can fit and seal both sides of the heat absorption component through the transverse guard plates fixed on both sides of the inner cavity, improving the overall liquid inlet stability. The pressure pump inputs gas into the elastic airbag on one side through a pipeline. After the elastic airbag expands, it drives the fixing part on the top of the pressure regulating seat to pull the front heat absorption panel to move relatively to both sides to adjust the unfolded area. The medium after heat collection enters the pressure cylinder on one side of the direction-adjusting bottom box through the drain ring. The adjusting airbag inflates and blows the gas into the pressure cylinder through the valve. The pressurized water liquid can impact the scraping plate on one side to scrape the inner wall of the liquid storage pipe, thereby avoiding the adhesion of scale on the inner wall. Therefore, the extrusion and return water ability after heat exchange can be improved, and the relative unfolded area of the heat absorption panel and the bottom heat exchange inner bladder can be controlled through gas linkage, improving the linkage control effect and meeting the overall use requirements.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1-10 , the present invention provides a technical solution: a solar flat plate collector, including a heat collection flexible shell 1, an endothermic component 5 for flexible expansion and heat exchange is fixedly installed in the inner cavity of the heat collection flexible shell 1, a water tank mechanism 2 is adjustably installed at one end of the heat collection flexible shell 1 to adapt to the expansion of the endothermic component 5, an adjusting mechanism 3 is provided at the other end of the heat collection flexible shell 1 to control the expansion of the endothermic component 5, a support component 6 is provided at the bottom of the inner cavity of the heat collection flexible shell 1, and the support component 6 is in contact with the endothermic component 5, and a driving mechanism 4 is provided between one side of the support component 6 and one side of the heat collection flexible shell 1;

[0045] The heat absorption component 5 includes a heat absorption panel 501, and the heat absorption panel 501 is a flexible stacked corrugated heat exchange film. A heat exchange inner bladder 503 is attached to the bottom of the heat absorption panel 501. The heat exchange inner bladder 503 is a flexible stacked corrugated heat exchange inner bladder 503, and the heat exchange inner bladder 503 is used for heat exchange and heat collection with the internal heat exchange medium by flexibly attaching to the heat absorption panel 501. Both the heat absorption panel 501 and the heat exchange inner bladder 503 are installed in the inner cavity of the heat collection flexible shell 1. The heat absorption component 5 further includes a drain ring 505 fixed to one side of the heat exchange inner bladder 503 for suppressing the liquid outflow rate. A plurality of pin shafts 506 are hinged in the inner cavity of the drain ring 505, and a contact plate 507 is fixedly connected to one side of the pin shaft 506. The drain ring 505 communicates with the adjustment mechanism 3 on one side. Both sides of the heat absorption panel 501 are fixedly installed on one side of the inner cavity of the heat collection flexible shell 1 through adjustment blocks 502, and both sides of the heat exchange inner bladder 503 are fixedly connected to one side of the inner cavity of the heat collection flexible shell 1 through connection plates 504.

[0046] The specific implementation method is as follows: When the heat absorption panel 501 is a flexible stacked corrugated heat exchange film, the flexible film can adjust the unfolded area under the action of the front-end adjustment mechanism 3 driving the heat collection flexible shells 1 on both sides to extend outwards. Heat absorption layers are coated on the inner cavities of both the heat absorption panel 501 and the heat exchange inner bladder 503 to improve the heat conduction ability and meet the requirements of heat exchange stability. Moreover, the flexible heat exchange inner bladder 503 can be synchronously unfolded and adapted to adjust the heat absorption and heat exchange area under the action of the top, the heat absorption panel 501, and the heat collection flexible shells 1 on both sides. Thus, the flexible solar flat heat collection can be realized through the cooperation of the heat absorption panel 501 and the heat exchange inner bladder 503, which can adapt to the assembly requirements of different installation positions. Furthermore, it can pull the internally connected heat absorption component 5 to adjust and unfold, and at the same time, it can protect the internal heat absorption component 5 to avoid the flexible components from cracking due to external impacts. Therefore, the contact heat absorption area can be effectively adjusted, which is beneficial to adjusting the heat exchange efficiency of the internal heat exchange medium through the unfolded top contact area. After the heat exchange inner bladder 503 absorbs and collects heat, the internal heat absorption medium can enter the drain ring 505 under the action of the subsequent water pressure. A plurality of contact plates 507 inside the drain ring 505 can receive the impact of the medium and are deflected and dispersed through the pin shafts 506 and then sent into the adjustment mechanism 3 on one side for pressurized pumping. Thus, the drain ring 505 can effectively receive and disperse the end medium to avoid excessive water pressure affecting heat exchange and heat collection.

[0047] The support assembly 6 includes a support crossbar 601. One side of the support crossbar 601 is fixedly connected to one side of the drive mechanism 4.

And a regulating seat 607 is fixedly installed on the other side of the support rib plate 606. And a sliding seat 611 is slidably connected to the outer walls of a plurality of regulating seats 607. And the sliding seat 611 is fixedly installed on one side of the inner cavity of the heat collection flexible shell 1.

And two fixing rods 609 arranged axially opposite to each other are slidably connected between a single group of a plurality of energy absorption plates 610. And both sides of the fixing rod 609 are fixedly connected with sliders 608. And one side slider 608 is slidably connected in the sliding seat 611. And the other side slider 608 is attached to one side of the support crossbar 601. And the energy absorption plate 610 is an elastic heat absorption member. And the cross-sectional shape of the energy absorption plate 610 is arc-shaped for receiving and absorbing the impact force of the medium;

[0048] The drive mechanism 4 includes a mounting plate 401. A motor 402 is fixedly installed on the top of the mounting plate 401.

The support assembly 6 further includes a liquid absorption pad 612. The liquid absorption pad 612 is fixedly connected to the bottom of the inner cavity of the heat collection flexible shell 1. A plurality of balls 613 are drivingly connected to the top of the liquid absorption pad 612. And the balls 613 are attached to the bottoms of the corresponding position energy absorption plates 610 and support rib plates 606 at the top.

[0049] As Figure 3 、 8As shown in FIGS. 9 and 10, the specific implementation manner is as follows: When the pressure of the heat exchange medium is too high, resulting in impact frequency vibration of the flexible heat exchange inner bladder 503 and affecting the service life, when controlling the rotation of the output shaft of the motor 402, the rotation of the output shaft of the motor 402 can drive the driving gear 403 to rotate. The rotation of the driving gear 403 can drive the driven rack 404 to pull the connecting block 405 on one side to move. The movement of the connecting block 405 can drive the driving rod 406 to move within the shaft sleeve in the heat collection flexible shell 1. The movement of the driving rod 406 can pull the end support cross bar 601 to move. The movement of the support cross bar 601 can drive a plurality of hinge seats 602 on one side to rotate relatively and pull the front sliding seat 604 to move. The movement of the sliding seat 604 can drive the lateral position of the support rib plate 606 on one side. The movement of the support rib plate 606 can realize the lateral pulling of the top-fitting heat exchange inner bladder 503 through the top wavy structure. After the wavy inner cavity at the bottom of the heat exchange inner bladder 503 is pulled and limited, it has corresponding support stress. Through the fitting and pulling of a plurality of support rib plates 606, the impact absorption capacity of the internal medium flow can be effectively improved. At the same time, when the sliding seat 604 is pulled, it can move upward outside the shaft body of the hinge seat 602 through the cooperation of the inclined surface of the bottom triangular plate 603, so as to drive the sliding seat 611 to pull the support rib plate 606 on one side to move upward and simultaneously squeeze the first spring 605 outside the shaft body. The movement of the support rib plate 606 can effectively enhance the longitudinal support force at the bottom of the top heat exchange inner bladder 503. At the same time, when the output shaft of the motor 402 rotates in reverse to drive the driven gear to reset, the first spring 605 can use its own elastic force to drive the sliding seat 604 and the support rib plate 606 on one side to reset, improving the adaptability in use. Through the provided energy absorption plate 610, the energy absorption plate 610 is clamped and assembled between the support rib plates 606 on both sides. When the medium moves and deflects in the wavy cavity at the bottom of the heat exchange inner bladder 503, the deflection force can be transmitted to the surface of the energy absorption plate 610 through the abutment with the energy absorption plate 610 on one side. The energy absorption plate 610 can absorb the corresponding deflection force through the sliding outside the fixed rod 609, improving the fitting and limiting support ability of the adjacent energy absorption plates 610 for the heat exchange inner bladder 503, improving the stability and safety of the bottom support of the heat exchange inner bladder 503, avoiding the impact causing frequency vibration of the heat exchange inner bladder 503 and affecting the service life. At the same time, the energy absorption plate 610 can absorb the corresponding heat storage capacity by using the self-heat exchange material to ensure the relative temperature in the heat collection flexible shell 1. By setting the shaft sleeve as a waterproof shaft sleeve, it can ensure that the water sealing effect can still be achieved in the case of the rupture of the internal heat exchange inner bladder 503, improving the corresponding treatment safety. When the energy absorption plate 610 and the support rib plate 606 move relatively, the relative folds of the energy absorption plate 610 and the support rib plate 606 can be fully attached to the bottom ball 613, so that the offset energy absorption friction can be effectively reduced through the fitting movement of the ball 613. And the ball 613 is a flexible energy absorption component, which can further improve the impact absorption ability. And the bottom liquid absorption pad 612 can effectively prevent external water vapor from eroding, improving the corresponding safety.

[0052] A filter screen plate 312 is hinged in the inner cavity of the pressure regulation seat 308. Receiving grooves are opened on both sides of the inner cavity of the filter screen seat 307. Anti - detachment blocks 314 are slidably connected in the two receiving grooves. A sliding ring 313 is fixedly connected between the two anti - detachment blocks 314. A broken inner network 315 is fixedly connected to one side of the sliding ring 313. A sliding sleeve is embedded on one side of the anti - detachment block 314. A sliding rod 316 is slidably connected in the sliding sleeve. A second spring 317 fixedly connected to both sides of the receiving groove is sleeved on the outer side wall of the sliding rod 316.

[0053] As Figure 1 and 4As shown in FIG. -7, the specific implementation method is as follows: When adding heat exchange medium, the main water tank 201 can initially filter impurities in the feeding medium through the cooperation of the water tank feeding seat 204 on one side and the active filter screen 205. Moreover, the flexible sheath 202 can be closely attached and sealed to both sides of the heat absorption component 5 through the horizontal guard plates 203 fixed on both sides of the inner cavity, preventing the medium in the main water tank 201 from leaking out due to the gap generated between the flexible sheath 202 and the horizontal guard plates 203 during the unfolding and movement, improving the overall liquid inlet stability. At the same time, when it is necessary to adjust and unfold the heat absorption component 5, the pressure pump 305 can input gas into the elastic air bag 306 on one side through the pipeline. After the elastic air bag 306 is forced to unfold, it can drive the pressure regulating seat 308 to move relatively through the filter screen seats 307 on both sides. The movement of the pressure regulating seat 308 can drive the top fixing part 303 to pull the front heat absorption panel 501 to move relatively to both sides to adjust the unfolding area, so that the relative area of the heat exchange component unfolding can be precisely controlled by the input gas volume, which is beneficial to controlling the heat exchange flow rate. And the pressure regulating seat 308 slides more stably through the stepped block on the top in the chute 302. At the same time, the water isolation pad 304 can seal the chute 302 on the top of the direction-adjusting bottom box 301 to ensure the water isolation effect. After the heat-collected medium enters the direction-adjusting bottom box 301 through the drain ring 505, it enters the pressure cylinder 311 on one side through the water inlet hole at the top of the hot water inlet pipe 310. At the same time, the pressure regulating seat 308 drives the extrusion block 318 on one side to press the extrusion rod 319 and inflate the regulating air bag 309. The inflation of the regulating air bag 309 blows the gas into the pressure cylinder 311 through the valve. The water liquid in the pressure cylinder 311 is forced to pressurize and enters the liquid storage pipe 7 through the pipeline on one side. The pressurized water liquid can impact the scraping plate on one side to scrape the inner wall of the liquid storage pipe 7, thereby avoiding the adhesion of scale on the inner wall. The scraping plate is sleeved at the end of the flexible pipe body and can be scraped and cleaned in the liquid storage pipe 7 through the impact of the water flow, so as to improve the extrusion and return water ability after heat exchange. And after the water liquid enters the filter screen seat 307 on one side, part of the impurities in the heat exchange medium can be filtered out through the filter screen plate 312 in the pressure regulating seat 308 on one side. At the same time, under the action of the water flow, the sliding ring 313 in the filter screen seat 307 can realize the staggered impurity removal between the broken inner net 315 on one side and the filter screen seat 307 through the sliding of the anti-detachment block 314 in the filter screen seat 307, thereby realizing the self-cleaning effect of the filtered impurities, which is beneficial to realizing the backwashing treatment. And the anti-detachment block 314 slides more stably through the sliding sleeve outside the sliding rod 316, and the second spring 317 can enhance the frequency vibration by using the impact force, prolonging the cutting and cleaning effect of the broken inner net 315 on the impurity flocs filtered by the filter screen seat 307.

[0054] Working principle: When in use, first add a heat exchange medium into the water tank main body 201 through an external pump body. The water tank main body 201 preliminarily filters the impurities of the feed medium through the cooperation of the water tank feed seat 204 on one side and the active filter screen 205. The flexible sheath 202 realizes the fitting and closing of both sides of the heat absorption component 5 through the transverse guard plates 203 fixed on both sides of the inner cavity. When it is necessary to adjust and expand the heat absorption component 5, the pressure pump 305 inputs gas into the elastic air bag 306 on one side through a pipeline. After the elastic air bag 306 is stressed and expanded, it drives the pressure regulating seat 308 to move relatively through the filter screen seats 307 on both sides. The movement of the pressure regulating seat 308 drives the top fixing part 303 to pull the front heat absorption panel 501 to move relatively to both sides to adjust the expansion area. The flexible heat exchange inner bag 503 is synchronously expanded and adapted to adjust the heat absorption and heat exchange area under the action of the top and the heat absorption panel 501 and the heat collection flexible shells 1 on both sides;

[0055] When it is necessary to adjust due to the impact frequency vibration of the flexible heat exchange inner bag 503 caused by excessive pressure of the heat exchange medium, which affects the service life, control the output shaft of the motor 402 to rotate. The rotation of the output shaft of the motor 402 drives the driving gear 403 to rotate. The rotation of the driving gear 403 drives the driven rack 404 to pull the connecting block 405 on one side to move. The movement of the connecting block 405 drives the driving rod 406 to move in the shaft sleeve of the heat collection flexible shell 1. The movement of the driving rod 406 pulls the end support cross bar 601 to move. The movement of the support cross bar 601 drives a plurality of hinge seats 602 on one side to rotate relatively and pull the front sliding seat 604 to move. The movement of the sliding seat 604 drives the relative horizontal position of the support rib plate 606 on one side. The movement of the support rib plate 606 realizes the horizontal pulling of the top-fitting heat exchange inner bag 503 through the top wavy structure. After the wavy inner cavity at the bottom of the heat exchange inner bag 503 is pulled and limited, it has corresponding support stress. The impact absorption capacity of the internal medium flow is effectively improved through the fitting and pulling of a plurality of support rib plates 606. The sliding seat 604 moves upward outside the shaft body of the hinge seat 602 through the cooperation of the inclined surface of the bottom triangular plate 603 when being pulled. The sliding seat 611 moves to pull the support rib plate 606 on one side to move upward and squeeze the first spring 605 outside the shaft body. The movement of the support rib plate 606 effectively improves the enhancement of the longitudinal support force of the bottom of the top heat exchange inner bag 503. When the output shaft of the motor 402 rotates in reverse to drive the driven gear to reset, the first spring 605 drives the sliding seat 604 and the support rib plate 606 on one side to reset by using its own elastic force. The energy absorption plate 610 is clamped and assembled between the support rib plates 606 on both sides. The medium moves and deflects in the wavy cavity at the bottom of the heat exchange inner bag 503. The deflection force is transmitted to the surface of the energy absorption plate 610 through the abutment with the energy absorption plate 610 on one side. The energy absorption plate 610 absorbs the corresponding deflection force through the sliding outside the fixed rod 609. The energy absorption plate 610 utilizes the self-heat exchange material to absorb the corresponding heat storage capacity. When the energy absorption plate 610 and the support rib plate 606 move relatively, the relative folds of the energy absorption plate 610 and the support rib plate 606 are fully attached to the bottom ball 613;

[0056] After the heat-collected medium enters the direction-adjusting bottom box 301 through the liquid discharge ring 505, it enters the pressure cylinder 311 on one side through the water inlet hole at the top of the hot water inlet pipe 310. The pressure regulating seat 308 drives the extrusion block 318 on one side to press the extrusion rod 319 and the regulating airbag 309 to inflate. The inflation of the regulating airbag 309 blows the gas into the pressure cylinder 311 through the valve flap. The water and liquid in the pressure cylinder 311 are forced to be pressurized and enter the liquid storage pipe 7 through the pipeline on one side. The pressurized water and liquid impact the scraping plate on one side to scrape the inner wall of the liquid storage pipe 7. The scraping plate is sleeved at the end of the flexible pipe body, and the scraping cleaning in the liquid storage pipe 7 is realized by the impact of the water flow. After the water and liquid enter the filter screen seat 307 on one side, part of the impurities in the heat exchange medium are filtered out by the filter screen plate 312 in the pressure regulating seat 308 on one side. Under the action of the water flow, the sliding ring 313 in the filter screen seat 307 slides through the anti-detachment block 314 in the filter screen seat 307 to realize the staggered impurity removal of the crushing inner net 315 on one side and the filter screen seat 307, thereby realizing the self-cleaning effect of the filtered impurities.
