DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] Example 1 like Figures 1-4 and Figure 8-Figure 9As shown, an energy-saving roof structure based on solar power generation includes a roof 1, a ridge fixing plate 2, a connecting block 3, and a total rotation rod 101; the roof 1 is provided with a first slope roof 1001 and a second slope roof 1002; the ridge of the roof 1 is bolted to the ridge fixing plate 2; the ridge fixing plate 2 is fixedly connected to two bilaterally symmetrical connecting blocks 3; the two connecting blocks 3 are rotatably connected to two total rotation rods 101; the total rotation rods 101 are distributed front to back; It also includes a partition swivel 102, a fixing frame 103, a snap-fit sealing block 105 and a photovoltaic panel 1111; each main rotating rod 101 is rotatably connected to a number of partition swivels 102; each partition swivel 102 is fixedly connected to a fixing frame 103; each fixing frame 103 is installed with two photovoltaic panels 1111; the front and rear ends of the photovoltaic panel 1111 are fixedly connected to the snap-fit sealing block 105; the snap-fit sealing block 105 on the photovoltaic panel 1111 is snapped together with the snap-fit sealing block 105 on the other photovoltaic panel 1111, thereby achieving a waterproof seal between the two photovoltaic panels 1111.

[0019] It also includes a support rod 104 and a fixing block 107; a through slot 10301 is opened on the fixing frame 103; the four eaves corners of the roof 1 are bolted to the fixing blocks 107; each fixing block 107 is rotatably connected to the support rod 104; the other end of the support rod 104 is located on the through slot 10301 adjacent to it.

[0020] It also includes an interception net 106; an interception net 106 is set on all fixing frames 103, and the lower part of the interception net 106 is fixed to the roof 1 by a clamp; the interception net 106 is deformable; the interception net 106 is square and one side is connected to the eaves, and one side is connected to the fixing frame 103, together forming a concave shape.

[0021] It also includes a guide plate 108; the front and rear sides of the roof 1 are respectively connected to the guide plate 108 through two fixed blocks 107 for common rotation; the rotation of the guide plate 108 is controlled by an electric shaft.

[0022] When installing photovoltaic panels 1111, which collect solar energy and convert it into electricity, on a gable roof (i.e., roof 1), the tiles covering roof 1 must first be removed. A solar photovoltaic base, which secures the photovoltaic panels 1111, must be installed in the exposed areas. Installing the solar photovoltaic base in these exposed areas damages the existing waterproof layer, necessitating a reapplying of the waterproof layer to the area where the base is installed. This process is labor-intensive and, due to the large number of solar photovoltaic bases installed, can cause significant damage to roof 1. Even if waterproofing measures are implemented after the waterproof layer is damaged, water seepage may still occur in roof 1 as the waterproof layer ages.

[0023] When using the present invention, the installer can directly fix the two photovoltaic panels 1111 on the ground in advance by snapping the sealing blocks 105 on the two photovoltaic panels 1111. At this time, the snapping sealing blocks 105 are as shown in FIG. Figure 8 As shown, a card slot is provided on the snap-fit sealing block 105, and the two snap-fit sealing blocks 105 are locked in the card slot to lock the two photovoltaic panels 1111, and the cable connectors of the two photovoltaic panels 1111 are connected, thereby avoiding the problem of inconvenience in connecting the cable connectors on the back of the photovoltaic panels 1111 due to the close distance between the roof 1 and the photovoltaic panels 1111 during the existing installation; then the two hybrid photovoltaic panels 1111 fixed together are suspended to the roof 1, and the two photovoltaic panels 1111 are fixed to the fixing frame 103. After all the fixing frames 103 are installed, the whole is fixed together, and the partition swivel is 102 is fixed as a whole on the main rotating rod 101 and cannot rotate independently. After the fixing frame 103 on the second sloping roof 1002 is set in the same way, the main rotating rod 101 is connected to an external motor. The installation of the present invention is completed. When light directly hits the second sloping roof 1002, the main rotating rod 101 close to the first sloping roof 1001 is driven by the output end of the external motor to rotate clockwise from right to left. The main rotating rod 101 drives the partition rotating ring 102 and the fixing frame 103 to rotate. The photovoltaic panel 1111 located on the first sloping roof 1001 is driven by the fixing frame 103 to rotate clockwise from right to left as shown in the figure. Figure 2 In the state shown, the photovoltaic panels 1111 located on the first sloping roof 1001 are at the same inclination angle as the second sloping roof 1002, so that the photovoltaic panels 1111 located on the first sloping roof 1001, which were originally restricted by the shape of the roof 1 and could not be directly hit by the light when the second sloping roof 1002 is directly hit, are fully exposed to the light, thereby improving the efficiency of the photovoltaic panels 1111 in collecting solar energy and converting it into electrical energy. At the same time, the two photovoltaic panels 1111 are connected and sealed together by snapping on the sealing block 105, thereby avoiding the need to apply sealant to the connection part of the two photovoltaic panels 1111 when installing the photovoltaic panels 1111 in the existing manner, and after applying the sealant, a water guide groove needs to be set under the connection part to avoid water leakage and dripping on the cable joint.

[0024] Furthermore, in order to prevent the deformation of the fixing frame 103 and damage to the photovoltaic panel 1111 caused by strong wind, a support rod 104 and a fixing block 107 are provided. When installing, the fixing block 107 is installed on the four eaves corners of the roof 1, and the support rod 104 connected to the fixing block 107 is rotated as shown in FIG. Figure 4As shown, the other end of the support rod 104 is installed in the through groove 10301 of the fixing frame 103. By installing the support rod 104 in the through groove 10301, when the wind is strong, the rotation angle of the photovoltaic panel 1111 is limited by the support rod 104, thereby avoiding the fixing frame 103 from bending and squeezing the photovoltaic panel 1111, thereby damaging the photovoltaic panel 1111. At the same time, the rotation angle of the support rod 104 is limited by the through groove 10301. When the photovoltaic panel 1111 rotates close to the first sloping roof 1001, there is a certain distance between it and the first sloping roof 1001, and the tiles on the first sloping roof 1001 will not be squeezed and damaged.

[0025] In photovoltaic panels 1111 Figure 2 As shown, in order to prevent external garbage such as leaves from falling on the first slope roof 1001 without the protection of the photovoltaic panel 1111 and getting stuck between the first slope roof 1001 and the photovoltaic panel 1111 when the photovoltaic panel 1111 rotates, an interception net 106 is provided. When light directly hits the second slope roof 1002, the photovoltaic panel 1111 on the first slope roof 1001 is blocked. Figure 2 As shown, the interception net 106 connected to the first sloping roof 1001 is stretched and expanded as the photovoltaic panel 1111 rotates, intercepting the garbage falling toward the first sloping roof 1001 on the outside of the interception net 106, preventing the fallen garbage from being stuck between the first sloping roof 1001 and the photovoltaic panel 1111, and affecting the heat dissipation of the back panel of the photovoltaic panel 1111.

[0026] When light directly hits the first slope roof 1001, the external motor drives the main rotating rod 101 to rotate counterclockwise from right to left, driving the partition rotating ring 102 and the fixing frame 103 to rotate, so that the photovoltaic panels 1111 on the first slope roof 1001 are rotated from the left to the right. Figure 2 The status shown changes to Figure 1 In order to prevent the garbage adhering to the interception net 106 from affecting the heat dissipation of the photovoltaic panels 1111, causing the conversion efficiency of the photovoltaic cells to decrease as the temperature rises, affecting the conversion efficiency between the photovoltaic panels 1111, a guide plate 108 is provided. When the light directly hits the first slope roof 1001, the guide plate 108 is as shown. Figure 3 As shown, the guide plate 108 guides the rainwater falling along the surface of the photovoltaic panel 1111, and the interception net 106 Figure 2 becomes Figure 1During the state, the guide plate 108 is controlled to rotate counterclockwise from right to left, so that when the interception net 106 is retracted and folded, it is scraped by the guide plate 108, causing the garbage on the front side of the interception net 106 to fall. At the same time, during the retraction and folding of the interception net 106, one end of the support rod 104 slides in the through groove 10301, and the support rod 104 scrapes against the left and right sides of the interception net 106, causing the garbage on the left and right sides of the interception net 106 to fall, thereby avoiding the high temperature of the back plate of the photovoltaic panel 1111 and the inability to dissipate heat in time, affecting the conversion efficiency of the photovoltaic panel 1111.

[0027] Furthermore, when it is necessary to inspect the back side of the photovoltaic panel 1111 and replace the cable connector, it is only necessary to release the lock of the fixing frame 103 of the photovoltaic panel 1111 to be inspected and the other fixing frames 103, and unlock the lock of the partition swivel 102, so that the two photovoltaic panels 1111 whose cable connectors need to be replaced can be put into the same position under the operation of the maintenance personnel. Figure 9 In the state shown, the cable is exposed, which is convenient for replacement, thus avoiding the situation in which the photovoltaic panel 1111 of the cable to be replaced needs to be dismantled before replacement.

[0028] Example 2 On the basis of Example 1, Figures 1-11 As shown, a protective film 201 is also included; all photovoltaic panels 1111 on the first sloping roof 1001 are commonly provided with a protective film 201, and all photovoltaic panels 1111 on the second sloping roof 1002 are commonly provided with a protective film 201, and the protective film 201 has high light transmittance.

[0029] It also includes an electric slide rail 203, a slider 204, a connecting plate 205 and a cleaning plate 206; four connecting plates 205 are bolted to the roof 1; each connecting plate 205 is connected to the adjacent side of the sloping roof; two electric slide rails 203 are bolted to each connecting block 3, and each electric slide rail 203 is fixed to the adjacent connecting plate 205; each electric slide rail 203 is slidably connected to a slider 204; the two corresponding sliders 204 located at the two ends of the same sloping roof are jointly fixed with a cleaning plate 206.

[0030] It also includes a connecting membrane 202; a connecting membrane 202 is connected to the rear side of the snap-fit sealing block 105 close to the main rotating rod 101 on the first sloping roof 1001 and the second sloping roof 1002.

[0031] The protective film 201 is coated with a hydrophobic coating to reduce the amount of garbage adhering to the protective film 201 .

[0032] A high-strength cloth is fixed to each cleaning plate 206 , and the high-strength cloth is rolled up in the ridge fixing plate 2 ; an acoustic sensor is provided in the ridge fixing plate 2 .

[0033] Silica gel is provided at the bottom of the cleaning plate 206, and the silica gel contacts the protective film 201 to scrape and clean impurities adhering to the protective film 201, thereby preventing the cleaning plate 206 from scratching the protective film 201 during cleaning.

[0034] The foreign sand, dust, leaves and other garbage adhered to the photovoltaic panel 1111 will block the sunlight, resulting in energy loss and increased surface temperature, shortening the life of the photovoltaic panel 1111 and affecting the surface quality of the battery cell. Therefore, a protective film 201 is provided on the surface of the photovoltaic panel 1111 to prevent the fallen garbage from falling on the protective film 201 and not coming into contact with the photovoltaic panel 1111. In addition, the garbage that falls on the protective film 201 will fall along the inclined surface when the photovoltaic panel 1111 rotates to adapt to the direct light angle. The protective film 201 prevents garbage from falling onto the photovoltaic panel 1111, which may cause the garbage to scrape against the surface of the photovoltaic panel 1111 and damage the photovoltaic panel 1111 when the garbage is cleaned. It should be noted that when the garbage falls along the inclined surface of the protective film 201, the protective film 201 is connected to the photovoltaic panel 1111 near the main rotating rod 101, so that the garbage falling along the inclined surface will not fall onto the main rotating rod 101 and affect the rotation of the main rotating rod 101.

[0035] Furthermore, when hail falls, in order to prevent hail from damaging the photovoltaic panel 1111, when the acoustic sensor detects the sound of hail hitting the protective film 201, the main rotating rod 101 is controlled to rotate so that the photovoltaic panel 1111 is Figure 1 As shown, the slider 204 is then controlled to slide along the electric slide rail 203 from the ridge to the eaves of the roof 1, and the slider 204 drives the cleaning plate 206 to slide along the surface of the protective film 201. The cleaning plate 206 cleans the garbage dropped on the cleaning plate 206 during the sliding process. At the same time, the fallen hail rolls and falls along the first slope roof 1001 and the second slope roof 1002. Furthermore, when the slider 204 slides close to the eaves of the roof 1, the cleaning plate 206 drives the high-strength cloth to be fully unfolded and cover the photovoltaic panel 1111. The high-strength cloth is suspended in the air and parallel to the photovoltaic panel 1111, intercepting the continuously falling hail and protecting the photovoltaic panel 1111 from damage.
