[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is provided with a solar panel. In clear weather, the upper surface of the solar panel forms a plane and can be used for power generation. In rainy days, two solar panels can form an angle to divert rainwater. When encountering heavy rain, the two solar panels continue to rotate to realize the storage of the solar panels, which can effectively reduce the damage of the solar panels caused by heavy rain and realize the comprehensive utilization of energy.

After the contact contacts the electromagnet contact, the electromagnet can be energized, and the solar panel can be driven to rotate through the connecting rod. At this time, the rainwater can be diverted. When the rainfall is large enough, the contact continues to descend. At this time, the current intensity passed into the electromagnet is further increased, which can drive the solar panel to rotate further, so that the solar panel can be stored. The change of rainwater can be better sensed and corresponding changes can be made in time. It has high reliability, is easy to maintain, and has a long service life.

[0038] like Figure 1-Figure 7 As shown, this embodiment proposes a roof structure with rainwater collection and utilization function, including:

[0039] At least one group of solar energy units is arranged on the roof surface 13. One group of solar energy units includes two solar panels 1 that can rotate relative to or apart from each other. According to the size of the roof surface 13, several groups of solar panels 1 can be arranged to improve the efficiency of power generation.

[0040] When the two solar panels 1 rotate relative to each other, the two solar panels 1 form an angle for diverting rainwater. At this time, an obtuse angle is formed between the solar panels 1. When rainwater falls on the solar panels 1, the rainwater can be diverted, which can reduce the obstruction of the solar panels 1 to rainwater collection and play a role in drainage, making it easier to collect and utilize rainwater.

[0041] When the two solar panels 1 rotate away from each other, the upper surfaces of the two solar panels 1 form a plane for generating electricity. When the weather is clear, after the solar panels 1 form a plane, their angles can better adapt to sunlight and facilitate power generation, so it will not affect the power generation work. At the same time, when it rains, rainwater can also be diverted to facilitate rainwater collection.

[0042] The water collecting box 6 is arranged at the angle between the two solar panels 1 to collect rainwater. The water collecting box 6 is connected to the water outlet pipe 7 to discharge water.

[0043] The shed surface 13 is connected to a rotating seat 23 for supporting the solar panel 1, the rotating seat 23 is rotatably connected to the main rod 4, the second rotating shaft 15 is rotatably connected to both sides of the main rod 4, the second rotating shaft 15 is fixedly connected to the connecting rod 14, the two connecting rods 14 are rotatably connected to the two solar panels 1 through the first rotating shaft 2 respectively, when the second rotating shaft 15 rotates, it can drive the connecting rod 14 to rotate, and the connecting rod 14 can drive the solar panel 1 to rotate.

[0044] The rotating seat 23 is provided with an annular groove, and the main rod 4 is fixedly connected with a plurality of guide rods arranged in the vertical direction. The guide rods can slide in the annular groove, and the guide rods always slide in the annular groove. Through the structure of the coordinated guide rods and the annular groove, the rotating seat 23 can support the main rod 4, so that the main rod 4 can rotate around the rotating seat 23.

[0045] The main rod 4 is provided with a square hole 32 arranged in the vertical direction. The rotating seat 23 is slidably connected with a square shaft 26 that moves in the vertical direction. The lower end of the square shaft 26 is connected with a second spring 27. The lower end of the second spring 27 is connected to the rotating seat 23. The upper end of the square shaft 26 is fixedly connected with a round rod 25. The second spring 27 is used for resetting the square shaft 26.

[0046] The round rod 25 is movably arranged in the square hole 32. When the square shaft 26 slides into the square hole 32, the main rod 4 can be locked relative to the rotating seat 23. When the square shaft 26 slides out of the square hole 32, the main rod 4 can rotate around the rotating seat 23. In the initial state, under the action of the second spring 27, the square shaft 26 is located in the square hole 32, and the main rod 4 cannot rotate at this time. The lower end of the square hole 32 is an inclined surface, and the setting of the inclined surface can facilitate the square shaft 26 to slide into the square hole 32 under the action of the second spring 27.

[0047] A slide groove 5 is provided on the main rod 4, and a slide rod 3 is slidably connected in the slide groove 5. Both solar panels 1 are rotatably connected to the slide rod 3. The length of the slide groove 5 is suitable enough to provide guidance and limit for the movement of the slide rod 3. The slide rod 3 can only slide along the length direction of the slide groove 5.

[0048] When the slide bar 3 slides to the upper end of the slide slot 5 , the upper surfaces of the two solar panels 1 form a plane. When the slide bar 3 slides to the lower end of the slide slot 5 , the slide bar 3 can drive the round rod 25 to slide, so that the square shaft 26 slides out of the square hole 32 .

[0049] When the slide bar 3 slides to the end of the slide groove 5, which specifically refers to the top of the slide groove 5, the upper surfaces of the two solar panels 1 form a plane. In the initial state, under the action of the gravity of the solar panel 1 itself, the slide bar 3 will slide to the top of the slide groove 5. In order to facilitate the realization of this state, a counterweight block can also be placed at the outer end of the solar panel 1.

[0050] A rack 29 that moves horizontally is slidably connected in the slide groove 5. The rack 29 is connected to an inclined rod 30 that can limit the slide rod 3 through a third spring 28. The upper surface of the inclined rod 30 is an inclined surface, and the lower surface of the inclined rod 30 is a horizontal surface.

[0051] The main rod 4 is fixedly connected to an air tube 8, and a slider 9 is slidably connected to the air tube 8. A gap is set between the slider 9 and the air tube 8 to facilitate the passage of wind and prevent the slider 9 from completely sliding out of the air tube 8 due to excessive wind force. At the same time, a limit block is fixedly connected to the air tube 8 to limit the movement of the slider 9, and the slider 9 can only slide within the limit block.

[0052] The main rod 4 is rotatably connected to a gear 31, which meshes with the rack 29; the gear 31 is coaxially connected to a rope-collecting wheel, which is wrapped with a pull rope 10, and the other end of the pull rope 10 is connected to the slider 9. The rope-collecting wheel is connected to a volute spring, which is used for resetting the rope-collecting wheel.

[0053] In the initial state, under the action of the third spring 28, the inclined rod 30 is located on one side of the slide bar 3, which will not affect the normal movement of the slide bar 3. Only under the action of wind, when the slider 9 is driven to move, the slider 9 can drive the inclined rod 30 to slide out. At this time, the inclined rod 30 can limit the slide bar 3 located below the inclined rod 30, and the solar panel 1 always remains in a close state to prevent the solar panel 1 from being opened due to factors such as excessive wind force, thereby improving the protection effect of the solar panel.

[0054] The second rotating shaft 15 is fixedly sleeved with a half gear 16, and the main rod 4 is also slidably connected with a small rack 17. The two ends of the small rack 17 are respectively meshed with the two half gears 16. When the small rack 17 moves, it can drive the two half gears 16 to rotate simultaneously. The small rack 17 is also fixedly connected with a permanent magnet 18, and the main rod 4 is connected with an electromagnet 19 that cooperates with the permanent magnet 18.

[0055] The reason for providing a half gear is to facilitate the assembly of the gear and the second rotating shaft. In addition, the rotation angle of the second rotating shaft 15 is also limited. The half gear can also be replaced by a full-tooth gear. In the initial state, the small rack 17 and the half gear 16 are not engaged. When the electromagnet 19 drives the small rack 17 to move, the small rack 17 will start to engage with the half gear 16, thereby driving the half gear 16 to rotate.

[0056] When the electromagnet 19 is energized, the electromagnet 19 and the permanent magnet 18 have the same magnetic properties and repel each other under the action of the magnetic force, which can drive the permanent magnet 18 to slide upward, thereby driving the half gear 16 to rotate. In order to facilitate the fixation of the small rack 17, the small rack 17 can also be connected with a small spring.

[0057] When the electromagnet 19 is not energized, the small spring can be used to reset the small rack 17. When the electromagnet 19 is energized, the small spring can be compressed. As the current increases, the magnetism of the electromagnet 19 can be enhanced. The stronger the current, the more turns the half gear 16 makes, and the smaller the angle between the solar panels 1.

[0058] The ceiling surface 13 is fixedly connected with a plurality of telescopic cylinders 62, which are arranged in a vertical direction. A plurality of telescopic cylinders 62 can be arranged to facilitate supporting the water collecting box 6. A telescopic rod 61 is slidably connected inside the telescopic cylinder 62. The telescopic rod 61 is connected to the telescopic cylinder 62 through a first spring 24, and the upper end of the telescopic rod 61 is fixedly connected to the water collecting box 6.

[0059] The first spring 24 is disposed in the telescopic tube 62 . The lower end of the first spring 24 is connected to the telescopic tube 62 , and the upper end of the first spring 24 is connected to the telescopic rod 61 . The first spring 24 is used for supporting and resetting the telescopic rod 61 .

[0060] The telescopic rod 61 is connected to the contact 20, and the telescopic cylinder 62 is connected to the empty contact 21 and the electromagnet contact 22 in sequence from top to bottom; the electromagnet contact 22 is a slidable variable resistor, specifically a sliding rheostat, and the contact 20 replaces the slider in the sliding rheostat. When the contact 20 slides along the electromagnet contact 22, the current intensity passed into the electromagnet 19 can be changed. When the current increases, the magnetism of the electromagnet 19 becomes stronger, which can drive the permanent magnet 18 to move a longer distance.

[0061] When the contact 20 and the empty contact 21 are in contact, the electromagnet 19 is not energized. In the initial state, under the action of the first spring 24, the contact 20 and the empty contact 21 are in contact. The water outlet pipe 7 is arranged at a position slightly below the water collecting box 6. As the rainwater in the water collecting box 6 is collected, the water collecting box 6 can be driven to descend, thereby driving the contact 20 to move downward.

[0062] When the contact 20 contacts the electromagnet contact 22, the electromagnet 19 is energized, and the telescopic rod 61 moves to the bottom. A stop block may be fixedly connected to the lower end of the telescopic tube 62, and the stop block supports the telescopic rod 61. At this time, the telescopic rod 61 cannot continue to descend, and the electromagnet 19 is energized.

[0063] The diameter of the water outlet pipe 7 determines the water outlet speed of the water outlet pipe 7. In actual use, the diameter of the water outlet pipe 7 can be reasonably adjusted to control the water outlet speed. When the water inlet speed is much greater than the water outlet speed, it can be explained as heavy rain. At this time, the contact 20 continues to descend, so that the current is further enhanced, thereby realizing the further storage of the solar panel 1.

[0064] In order to facilitate the resetting of the water collecting box 6, a small opening may be provided on the bottom surface of the water collecting box 6. The aperture of the small opening is small enough so as not to affect the collection of rainwater. When rainwater accumulates in the water collecting box 6 and the height of the rainwater does not reach the position of the outlet pipe 7, the rainwater in the water collecting box 6 may flow out through the small opening, which is convenient for resetting the water collecting box 6. At the same time, when the rainfall is small enough and there is no meaning of collecting it, due to the existence of the small opening, the water collecting box 6 will not drop to the state where the contact 20 and the electromagnet contact 22 are in contact, so the solar panel 1 still generates electricity.

[0065] The present invention also proposes a method for using a roof structure with a rainwater collection and utilization function, which also includes the above-mentioned roof structure with a rainwater collection and utilization function, including the following steps:

[0066] When power generation is required: the slide bar 3 slides to the end of the upper end of the slide slot 5, and the upper surfaces of the two solar panels 1 form a plane for power generation;

[0067] When it rains, rainwater enters the water collecting box 6, driving the water collecting box 6 down, and the telescopic rod 61 slides downward in the telescopic cylinder 62, compressing the first spring 24, and the telescopic rod 61 drives the contact 20 to move. When the contact 20 contacts the electromagnet contact 22, the electromagnet 19 is energized.

[0068] The electromagnet 19 drives the permanent magnet 18 to move, the permanent magnet 18 drives the small rack 17 to move, the small rack 17 drives the connecting rod 14 to rotate through the half gear 16, the connecting rod 14 drives the solar panel 1 to rotate, and the slide bar 3 slides in the slide groove 5. At this time, the two solar panels 1 form an angle that can divert rainwater, and the rainwater passes through the solar panel 1 and falls into the water collection box 6;

[0069] When it rains heavily, the speed at which rainwater enters the water collecting box 6 is greater than the water outlet speed of the water outlet pipe 7, and the rainwater drives the water collecting box 6 to further descend, and the telescopic rod 61 slides downward in the telescopic cylinder 62, and the telescopic rod 61 drives the contact 20 to move. At this time, the current intensity of the electromagnet 19 is further increased, which can drive the solar panel 1 to further rotate, so that the solar panel 1 can be stored;

[0070] At the same time, the sliding rod 3 can drive the round rod 25 to descend, and the round rod 25 drives the square shaft 26 to descend, and the square shaft 26 moves downward and out of the square hole 32, so that the second spring 27 is compressed. At this time, the round rod 25 is located in the square hole 32. Under the action of wind force, the solar panel 1 can be driven to rotate along the wind direction, and the main rod 4 can rotate around the round rod 25;

[0071] At the same time, the wind drives the slider 9 to move, and the slider 9 drives the rope collecting wheel to rotate through the pull rope 10, and the rope collecting wheel drives the gear 31 to rotate, and the gear 31 drives the rack 29 to move toward the direction close to the slide groove 5, and the rack 29 drives the inclined rod 30 to move. At this time, the slide bar 3 is located below the inclined rod 30, and the inclined rod 30 can prevent the slide bar 3 from moving upward.

[0072] In clear weather or with light rainfall, the slide bar 3 will not slide below the inclined bar 30. Only in heavy rain will the slide bar 3 slide further, driving the round bar 25 to move downward. Since the upper surface of the inclined bar 30 is an inclined surface, it will not affect the slide bar 3 from sliding below the inclined bar 30.

[0073] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
