DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-10 A photovoltaic panel waste heat utilization device comprises a base 1, and stands 11 are fixed on the top of both sides of the base 1. The waste heat utilization device is controlled by a controller and is characterized in that: a lower hinge 2 is fixed on the top of the base 1, an electric telescopic rod 21 is hinged on the surface of the lower hinge 2, an upper hinge 211 is hinged on the outside of the output shaft of the electric telescopic rod 21, a water pump 22 is fixed on the middle of the top of the base 1, a double-pass pipe 23 is fixed on the outside of the water outlet pipe of the water pump 22, and waste heat utilization components are arranged at both ends of the double-pass pipe 23, and the waste heat utilization components are used to recover and utilize the waste heat of the photovoltaic panel;

[0033] The waste heat utilization component includes a heat-conducting frame 3, both ends of the double-pass pipe 23 are fixed to the heat-conducting frame 3, the heat-conducting frame 3 is rotatably connected to the stand 11, partition plates 31 are fixed on both sides of the inner cavity of the heat-conducting frame 3, the inner cavity of the heat-conducting frame 3 is separated into two cold water chambers 32 and one hot water chamber 33 by the partition plates 31, a one-way valve 34 is fixed inside the partition plates 31, a drain pipe 35 is fixed at the bottom of the heat-conducting frame 3, and the drain pipe 35 is connected to the hot water chamber 33;

[0034] A plurality of cold water nozzles 4 are fixed on both sides of the heat-conducting frame 3, and the water inlet of the cold water nozzle 4 is located inside the cold water chamber 32, a photovoltaic panel frame 5 is fixed inside the heat-conducting frame 3, a photovoltaic panel 51 is fixed inside the photovoltaic panel frame 5, a card slot is opened on the top of the heat-conducting frame 3, and the card slot is located above the hot water chamber 33, the photovoltaic panel frame 5 is fixed inside the card slot of the heat-conducting frame 3, atomizing nozzles 41 are fixed near the card slot on both sides of the heat-conducting frame 3, and the water inlet of the atomizing nozzle 41 is located inside the hot water chamber 33;

[0035] During the specific operation, firstly, the external water pipe is connected to the water inlet of the water pump 22, so that cold water can be pumped through the water pump 22 and the two-way pipe 23. During actual use, when the sun shines on the surface of the photovoltaic panel 51, the photovoltaic panel 51 is controlled by the controller to convert solar energy into electrical energy. During the conversion process, as the sun rises in the east and sets in the west, the electric telescopic rod 21 is controlled to be ejected and returned through the induction of the sensor, and then the electric telescopic rod 21 drives the heat-conducting frame 3 to perform steering adjustment, and then the heat-conducting frame 3 drives the photovoltaic panel frame 5 and the photovoltaic panel 51 to perform steering adjustment, and then the photovoltaic panel 51 is always facing the sun, thereby ensuring the timely absorption of solar energy. This is the working principle of the photovoltaic panel that can adjust the angle according to the change of the light angle in the prior art, and the present invention will not be repeated in detail;

[0036] Specifically, in the process of the photovoltaic panel 51 converting solar energy into electric energy, as the sun continues to irradiate, the temperature of the surface of the photovoltaic panel 51 continues to rise, and then the temperature of the surface of the photovoltaic panel 51 and the photovoltaic panel frame 5 rises, and then waste heat is generated. At this time, the water pump 22 is started by the controller, so that the water pump 22 pumps cold water into the interior of the heat-conducting frame 3 through the two-way pipe 23, and the cold water is accumulated in the cold water chamber 32. Then, the one-way valve 34 is started by the controller, so that the cold water chamber 32 and the hot water chamber 33 are connected, so that the cold water in the cold water chamber 32 flows into the interior of the hot water chamber 33;

[0037] Since the card slot is located above the hot water chamber 33, and the photovoltaic panel frame 5 is fixed inside the card slot, the card slot of the heat-conducting frame 3 can be closed by the photovoltaic panel frame 5. When the heat-conducting frame 3 is closed, cold water accumulates inside the hot water chamber 33, and the bottom and frame of the photovoltaic panel frame 5 are immersed in the cold water in the hot water chamber 33, so that the cold water not only absorbs the residual heat at the bottom of the photovoltaic panel frame 5, but also absorbs the residual heat of the side frame of the photovoltaic panel frame 5, thereby increasing the amount of residual heat absorbed by the photovoltaic panel frame 5 as a whole, thereby improving the effect of residual heat utilization;

[0038] Furthermore, when the flip angle of the heat-conducting frame 3 is adjusted under the action of the electric telescopic rod 21, the flip angles of the photovoltaic panel frame 5 and the photovoltaic panel 51 are adjusted synchronously. After the adjustment, the photovoltaic panel frame 5 and the photovoltaic panel 51 are in an inclined state, that is, one end of the photovoltaic panel frame 5 is high and the other end is low, and the cold water nozzles 4 located at both ends of the heat-conducting frame 3 are in an inclined state, that is, the cold water nozzle 4 at one end is high, and the cold water nozzle 4 at the other end is low. At this time, the cold water nozzle 4 at the high end is started by the controller, so that the cold water nozzle 4 sprays cold water on the surface of the photovoltaic panel 51. During the spraying process, the cold water accelerates the flow of air above the photovoltaic panel 51, and then the accelerated flowing air accelerates to take away the excess heat above the photovoltaic panel 51, thereby protecting the photovoltaic panel 51 and preventing the photovoltaic panel 51 from being damaged due to overheating;

[0039] At the same time, after being sprayed, the cold water falls on the surface of the photovoltaic panel 51, and performs water cooling operation on the photovoltaic panel 51, thereby avoiding excessive heat accumulation on the surface of the photovoltaic panel 51, thereby further protecting the photovoltaic panel 51. At the same time, since the photovoltaic panel frame 5 and the photovoltaic panel 51 are in an inclined state, part of the cold water that absorbs heat on the surface of the photovoltaic panel 51 accumulates at the lower end of the photovoltaic panel 51 under the action of gravity, that is, the cold water accumulates at the lower end frame of the photovoltaic panel frame 5. At this time, the accumulated water that absorbs the heat of the photovoltaic panel 51 transfers the heat to the frame of the photovoltaic panel frame 5 again, so that the frame of the photovoltaic panel frame 5 further absorbs the heat of the photovoltaic panel 51, and then transfers the heat to the accumulated water in the hot water chamber 33 through the frame of the photovoltaic panel frame 5 again, thereby further improving the absorption of residual heat on the frame of the photovoltaic panel frame 5 by the hot water chamber 33;

[0040] Furthermore, when there is snow on the surface of the photovoltaic panel 51, in order to ensure sufficient absorption of solar energy, the electric telescopic rod 21 is required to drive the heat-conducting frame 3 and the photovoltaic panel frame 5 to adjust the angle, so that the photovoltaic panel frame 5 drives the photovoltaic panel 51 to adjust, so that the photovoltaic panel 51 is always tilted toward the sun, and at this time the photovoltaic panel 51 is still in a tilted state, that is, one end of the photovoltaic panel 51 is high, and the other end is low;

[0041] Because cold water is accumulated in the hot water chamber 33 under the action of the water pump 22, and when the photovoltaic panel 51 contains snow, the speed at which the cold water absorbs heat decreases, that is, when the cold water absorbs heat, it gradually changes from cold water to warm water, and then gradually changes to hot water. In the process of cold water changing into warm water, the high-end atomizing nozzle 41 is started by the controller, so that the atomizing nozzle 41 sprays out part of the warm water in the hot water chamber 33, so that the warm water forms a spray and is sprayed on the surface of the photovoltaic panel 51, thereby increasing the melting speed of the snow, thereby improving the absorption and conversion of solar energy by the photovoltaic panel 51, and further improving the generation and utilization of waste heat.

[0042] It should be noted that an infrared optical sensor can be installed on the surface of the photovoltaic panel frame 5 to determine whether there is snow on the surface of the photovoltaic panel 51, and a temperature sensor can be installed inside the hot water chamber 33 to sense the temperature change of the accumulated water in the hot water chamber 33, so as to ensure the use of low-temperature water, which is sprayed on the surface of the photovoltaic panel 51 under the action of the atomizing nozzle 41 to avoid damage to the photovoltaic panel 51 due to excessive temperature difference on the surface of the photovoltaic panel 51. At the same time, after the water temperature in the hot water chamber 33 is heated to meet the standard, it can be discharged to the outside through the drain pipe 35 for use.

[0043] Embodiment 2:

[0044] A limiting frame 6 is fixed on both sides of the top of one end of the heat-conducting frame 3, an air pump 61 is fixed inside the limiting frame 6, a conical tube 62 is fixed outside the air inlet pipe of the air pump 61, and an air bag 63 is fixed outside the air outlet pipe of the air pump 61, and the air bag 63 is located inside the limiting frame 6 in the initial state, a connecting plate 7 is fixed at one end of the air bag 63, a connecting rod 71 is fixed on the side of the connecting plate 7 close to the air bag 63, the connecting rod 71 passes through the heat-conducting frame 3 and the partition plate 31, and the connecting rod 71 is sealed and slidably connected to the heat-conducting frame 3 and the partition plate 31;

[0045] A plurality of linkage frames 72 are evenly fixed to the outside of the connecting rod 71, and the linkage frames 72 are located inside the hot water chamber 33. A rotating shaft 73 is fixed to the inner wall of the linkage frame 72, and a linkage plate 74 is rotatably connected to the outside of the rotating shaft 73. An elastic rope 75 is fixed to the bottom of the linkage plate 74, and one end of the elastic rope 75 is fixed to the bottom of the linkage frame 72. A plurality of limit card plates 8 are fixed to the bottom of the photovoltaic panel frame 5, and a plurality of adjustment slots 81 are provided at the bottom of the limit card plates 8. The number of the limit card plates 8 is equal to the number of the linkage frames 72.

[0046] Specifically, on the basis of the first embodiment, in summer, when the hot water chamber 33 is filled with cold water under the action of the water pump 22, in order to increase the speed at which the cold water absorbs heat from the frame and bottom of the photovoltaic panel frame 5, the air pump 61 can be started by the controller, so that the air pump 61 repeatedly inflates and exhausts the airbag 63. During the inflation and exhaust process, the airbag 63 repeatedly pushes out from the inside of the limiting frame 6 and then returns, and drives the connecting plate 7 to move synchronously, and the connecting plate 7 drives the connecting rod 71 to move synchronously, and the connecting rod 71 drives the linkage frame 72 to move synchronously, and the linkage frame 72 reciprocates inside the hot water chamber 33, and during the reciprocating movement, it plays a role in stirring the accumulated water in the hot water chamber 33, so that the flow rate of the cold water in the hot water chamber 33 is increased, and the area and speed at which the cold water contacts the bottom and frame of the photovoltaic panel frame 5 are increased, thereby improving the efficiency of the cold water in absorbing and utilizing the waste heat;

[0047] When the locking cam 72 is in contact with the locking cam 8, the locking cam 72 is automatically engaged with the locking cam 8. When the locking cam 72 is in contact with the locking cam 8, the locking cam 72 is automatically engaged with the locking cam 8. When the locking cam 72 is in contact with the locking cam 8, the locking cam 72 is automatically engaged with the locking cam 8. When the locking cam 72 is in contact with the locking cam 8, the locking cam 72 is automatically engaged with the locking cam 8. When the locking cam 72 is in contact with the locking cam 8, the locking cam 72 is automatically engaged with the locking cam 8.

[0048] The linkage plate 74 plays a role in stirring the water flow in the hot water chamber 33 during the flipping and resetting process, and further increases the flow rate of the cold water in the hot water chamber 33 during the vibration process, so that the efficiency of the cold water absorbing heat from the bottom and frame of the photovoltaic panel frame 5 is further improved;

[0049] When the airbag 63 is exhausted by the air pump 61, the gas is diffused through the conical tube 62, so that the gas in the airbag 63 is discharged toward the photovoltaic panel 51. Since the air pump 61 is used to assist the exhaust, the exhausted airflow has a certain initial velocity. When the gas in the airbag 63 is exhausted, an airflow is formed above the photovoltaic panel 51, which then plays a role in air cooling and heat dissipation above the photovoltaic panel 51, further protecting the photovoltaic panel 51 and preventing the surface temperature of the photovoltaic panel 51 from being too high.

[0050] Furthermore, when there is snow on the surface of the photovoltaic panel 51, the linkage plate 74 strikes the inner wall of the adjustment groove 81, causing the adjustment groove 81 and the limit card plate 8 to vibrate, so that the limit card plate 8 drives the photovoltaic panel frame 5 and the photovoltaic panel 51 to vibrate. When the photovoltaic panel frame 5 and the photovoltaic panel 51 are in an inclined state after adjusting the angle to follow the sun, the snow on the surface of the photovoltaic panel 51 vibrates synchronously with the vibration of the photovoltaic panel frame 5 by the limit card plate 8. As a result, the snow in the inclined state of the photovoltaic panel 51 is affected by gravity and vibration at the same time, and is easier to shake off and remove, thereby reducing the coverage and shading of the surface of the photovoltaic panel 51 by the snow, and then improving the absorption and conversion of solar energy by the photovoltaic panel 51, thereby improving the generation of waste heat and the absorption and utilization of waste heat.

[0051] Embodiment three:

[0052] A top frame 9 is fixed to one side of the connecting plate 7 close to the connecting rod 71. The top frame 9 is L-shaped. The horizontal portion of the top frame 9 is located at the top of the heat-conducting frame 3. The vertical portion of the top frame 9 is fixed to one end of the connecting rod 71 away from the connecting plate 7. A plurality of support frames 91 are fixed to the surface of the top frame 9. Cleaning scrapers 92 are fixed to both sides of the bottom of the support frames 91. A copper alloy spring 93 is fixed to the middle portion of the bottom of the support frames 91. A heat-conducting plate 94 is fixed to one end of the copper alloy spring 93. The cleaning scraper 92 is clamped inside the photovoltaic panel frame 5. The bottoms of the cleaning scraper 92 and the heat-conducting plate 94 are against the photovoltaic panel 51. The number of the support frames 91 is equal to the number of the linkage frames 72.

[0053] Specifically, on the basis of the second embodiment, when the air pump 61 repeatedly inflates and deflates the airbag 63, the airbag 63 drives the connecting plate 7 to move repeatedly, and the connecting plate 7 drives the top frame 9 to move repeatedly, so that the top frame 9 drives the support frame 91 to move repeatedly above the photovoltaic panel frame 5, and the support frame 91 drives the cleaning scraper 92 to move repeatedly inside the photovoltaic panel frame 5. The cleaning scraper 92 cleans the surface of the photovoltaic panel 51 during the movement, that is, cleans the sundries or bird droppings on the surface of the photovoltaic panel 51, so as to improve the efficiency of the photovoltaic panel 51 in converting solar energy into electric energy, and can also shovel the snow on the surface of the photovoltaic panel 51, and also avoids the freezing of the surface of the photovoltaic panel 51 after the warm water spray is sprayed in the process of the second embodiment, thereby further improving the efficiency of the photovoltaic panel 51 in converting solar energy into electric energy;

[0054] Furthermore, when the surface temperature of the photovoltaic panel 51 is too high, the support frame 91 drives the copper alloy spring 93 and the heat conducting plate 94 to move synchronously during repeated movement, and the heat conducting plate 94 is attached to the surface of the photovoltaic panel 51. When the heat conducting plate 94 moves, the heat on the surface of the photovoltaic panel 51 is transferred to the heat conducting plate 94, and then the heat is transferred to the copper alloy spring 93 and the support frame 91, and then the heat is transferred to the top frame 9, thereby making the top frame 9 have a heat dissipation effect, avoiding the excessive temperature of the surface of the photovoltaic panel 51, and thus protecting the photovoltaic panel 51;

[0055] At the same time, the heat of the top frame 9 can be transferred to the connecting plate 7 again, and then the heat is transferred to the connecting rod 71 and the linkage frame 72 through the connecting plate 7. Since the linkage frame 72 is located inside the hot water chamber 33, the heat on the surface of the photovoltaic panel 51 is transferred to the cold water in the hot water chamber 33 after multiple transfers, thereby absorbing the heat on the surface of the photovoltaic panel 51, thereby improving the efficiency of absorbing the overall waste heat of the photovoltaic panel frame 5 and the photovoltaic panel 51.

[0056] It should be noted that the connecting plate 7, connecting rod 71, linkage frame 72, top frame 9 and support frame 91 are all made of aluminum material, so as to reduce the heat loss during heat transfer between the components, to maximize the absorption of waste heat, and to prevent the excessive weight of the present invention from affecting the support of the base 1 and the stand 11 to the heat-conducting frame 3. The cleaning scraper 92 is made of silicone to avoid scratching the photovoltaic panel 51, and the copper alloy spring 93 ensures that the heat-conducting plate 94 is always in contact with the surface of the photovoltaic panel 51. At the same time, the surface of the heat-conducting plate 94 is arranged in an arc shape to avoid scratching the photovoltaic panel 51 by the heat-conducting plate 94.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
