[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] The embodiments of the present invention provide a distributed photovoltaic access and regulation device. It includes an installation component 1. Exemplarily, as Figure 1 and Figure 2 shown, an adjustment component 2 is installed on the output end of the installation component 1. A frame component 3 is movably clamped on the adjustment component 2. Several groups of access components 4 are equidistantly arranged on the frame component 3. Several groups of regulation and protection components 5 are equidistantly installed on each group of access components 4.

[0037] Exemplarily, as Figure 3As shown, the installation component 1 includes a mounting plate 101, on which a number of groups of threaded holes 102 are equidistantly arranged. On both side walls of the mounting plate 101, two groups of rotating rods 103 are symmetrically installed. On the outer wall of each group of rotating rods 103, a support plate 104 is rotatably connected. On the top of each group of support plates 104, a vacuum tube 105 is installed. On the top of each group of vacuum tubes 105, a vacuum suction cup 106 is connected. On the outer wall of each group of vacuum tubes 105, a vacuum pump 107 is installed. On the top of the mounting plate 101, a first electric push rod 108 is installed.

[0038] Start installing the photovoltaic structure. After determining the installation position, place the mounting plate 101 at the specified position, and then perform threaded installation through the threaded holes 102. Subsequently, adjust the height through the first electric push rod 108. And when quick installation and hanging positioning are required, rotate the support plate 104 so that the support plate 104 rotates and adjusts its position on the outer wall of the rotating rod 103. Then make the vacuum suction cup 106 fit with the installation point, and start the vacuum pump 107 to evacuate the air between the two, so that the inside of the vacuum suction cup 106 is in a negative pressure state, improving the adsorption of the structure; improving the installation effect of the device and the compatibility of the structure installation at the same time.

[0039] Exemplarily, as Figure 4 shown, the adjustment component 2 includes a first fixing plate 201, the bottom of which is installed on the output end of the first electric push rod 108. A second fixing plate 202 is arranged directly above the first fixing plate 201. On the top of the first fixing plate 201, a number of groups of movable collar 203 are equidistantly installed. A rotating column 204 is rotatably connected inside the movable collar 203. On the outer wall of the rotating column 204, a number of groups of fixed collar 205 are fixedly sleeved at equal intervals. On the top of the first fixing plate 201, a first motor 206 is installed, and the output end of the first motor 206 is drivingly connected to the rotating column 204. On the top of the second fixing plate 202, a second motor 207 is installed, and a clamping and limiting plate 208 is drivingly connected to the output end of the second motor 207.

[0040] In order to improve the light source receiving effect of several groups of photovoltaic panel bodies 402, when it is necessary to adjust the angle according to the light source, the first motor 206 is first started to drive the rotating column 204 to rotate. The rotating column 204 rotates in the movable ring 203 and drives the fixed ring 205 to rotate. The fixed ring 205 drives the frame body 301 clamped on the clamping limit plate 208 to rotate while rotating. When the frame body 301 moves to the specified angle, several groups of photovoltaic panel bodies 402 begin to access the light source, and then the absorbed light source is converted through the inverter body 403, and then transmitted to the load wire structure. Since the light source rises in the east and sets in the west, in order to ensure the continuous access of the light source, when the light source is in the west setting state, the second motor 207 is started to drive the photovoltaic panel body 402 to rotate, and then the photovoltaic panel body 402 is driven by the first motor 206 again to adjust the angle, thereby improving the light source access effect while improving the compatibility of the angle adjustment.

[0041] For example, Figure 5 and Figure 6 As shown, the frame assembly 3 includes a frame body 301, the bottom of the frame body 301 is movably connected to the clamping limit plate 208, a plurality of groups of mounting rings 302 are evenly spaced on the outer wall of the frame body 301, and a group of wear-resistant pads are installed on the inner wall of each group of mounting rings 302, a third fixing plate 303 is installed on one side wall of the frame body 301, a fourth fixing plate 304 is installed on one side wall of the third fixing plate 303, and a plurality of groups of third motors 305 are evenly spaced on one side wall of the fourth fixing plate 304, and a transmission layer is installed on the output end of each group of the third motors 305. A group of rotating circular boxes 306 are dynamically connected, and the outer wall of each group of rotating circular boxes 306 is slidably fitted on the inner wall of the mounting ring 302. A constant temperature column 307 is installed on the inner wall of the rotating circular box 306. A second electric push rod 308 is installed on the inner wall of one side of the rotating circular box 306. A sliding ring 309 is installed on the output end of the second electric push rod 308. The outer wall of the sliding ring 309 is slidably fitted on the inner wall of the rotating circular box 306. The inner wall of the sliding ring 309 is slidably fitted on the outer wall of the constant temperature column 307. A number of groups of condensation blocks 310 are installed at equal intervals on the inner wall of the rotating circular box 306.

[0042] For example, Figure 7As shown, the access component 4 includes a connecting plate 401. One end of each group of the connecting plates 401 is connected to the rotating round box 306. On one side wall of each group of the connecting plates 401, a number of groups of photovoltaic panel bodies 402 are evenly distributed at equal intervals. One inverter body 403 is electrically connected to each group of the photovoltaic panel bodies 402. A number of access terminal bodies 404 are electrically connected to each group of the inverter bodies 403. Two groups of first connection blocks 405 are symmetrically installed on both side walls of each group of the connecting plates 401. One third electric push rod 406 is installed on the top of each group of the first connection blocks 405. One second connection block 407 is installed on the output end of each group of the third electric push rods 406. One third connection block 408 is installed on one side wall of each group of the second connection blocks 407. One cleaning plate body 409 is connected between the two groups of the third connection blocks 408. The output end of each group of the cleaning plate bodies 409 is slidably attached to the outer wall of the photovoltaic panel body 402.

[0043] When the photovoltaic panel body is used for outdoor operations, its surface is extremely likely to be contaminated with impurities. To improve the usage effect of the photovoltaic panel body 402, start the third electric push rod 406 to push the second connection block 407 to rise. While the second connection block 407 is rising, it drives the two groups of third connection blocks 408 to rise accordingly. While the two groups of third connection blocks 408 are rising, they drive the cleaning plate body 409 to clean the surface of the photovoltaic panel body 402, avoiding the problem of light source access not being in place due to impurity residue and improving the cleaning effect of the device.

[0044] When it is necessary to adjust the distributed photovoltaic panel body 402, start the designated third motor 305 to drive the rotating round box 306 to rotate within the installation ring 302, and then drive the designated number of groups of photovoltaic panel bodies 402 to rotate. The photovoltaic panel body 402 starts to access the light source when it rotates to the designated position. And to extend the service life of the device, when the photovoltaic panel body 402 is working, cool air is conveyed into the connecting plate 401 through the condensation block 310, so that the cool air accumulates in the connecting plate 401 to assist in cooling the photovoltaic panel body 402, improving the adjustment effect of the distributed photovoltaic structure.

[0045] Exemplarily, such as Figure 8As shown in the figure, the regulation and protection component 5 includes a fourth connection block 501. One end of each group of the fourth connection blocks 501 is installed on one side wall of one group of photovoltaic panel bodies 402. One group of fourth electric push rods 502 is installed on one side wall of each group of the fourth connection blocks 501. One group of fifth connection blocks 503 is installed on the output end of each group of the fourth electric push rods 502. One group of limit frames 504 is installed on one side wall of each group of the fifth connection blocks 503. One group of inflatable bag structures 505 is installed on the inner wall of each group of the limit frames 504. One group of air pumps 506 is installed on the outer wall of each group of the limit frames 504. The output end of each group of the air pumps 506 is communicated with the input end of the inflatable bag structure 505.

[0046] When the photovoltaic structure is working, first pass several groups of load wire structures through the limit frames 504 and then electrically connect them to several groups of access end bodies 404. Then start the fourth electric push rod 502 to push the fifth connection block 503 to move towards the inverter body 403. Then start the air pump 506 to fill the inflatable bag structure 505 with gas, so that after the inflatable bag structure 505 expands, it wraps and limits the load wire structure, avoiding the problem of line shaking. And when a short circuit occurs during the subsequent working process, the fourth electric push rod 502 can be started to drive the load wire structure to disconnect from the access end body 404, improving the protection effect of the photovoltaic line and the stability effect of the line at the same time.

[0047] The photovoltaic panel body 402 starts to access the light source. Then the inhaled light source is converted by the inverter body 403 and then transported into the load wire structure. Start the designated third motor 305 to drive the rotating round box 306 to rotate in the installation ring 302, driving the designated several groups of photovoltaic panel bodies 402 to rotate. When the photovoltaic panel body 402 rotates to the designated position, it starts to access the light source at different angles, so that the load input power of the distributed inverter body can be regulated, improving the photovoltaic access effect and the photovoltaic regulation effect at the same time.

[0048] Pass several groups of load wire structures through the limit frames 504 and then electrically connect them to several groups of access end bodies 404. Then start the fourth electric push rod 502 to push the fifth connection block 503 to move towards the inverter body 403. Then start the air pump 506 to fill the inflatable bag structure 505 with gas, so that after the inflatable bag structure 505 expands, it wraps and limits the load wire structure, avoiding the problem of line shaking. And when a short circuit occurs during the subsequent working process, the fourth electric push rod 502 can be started to drive the load wire structure to disconnect from the access end body 404, improving the protection effect of the photovoltaic line and the stability effect of the line at the same time.

[0049] After determining the installation position, place the mounting plate 101 at the designated position, then perform threaded installation through the threaded holes 102, and then adjust the height through the first electric push rod 108. And when quick installation and hanging positioning are required, rotate the support plate 104 so that the support plate 104 rotates and adjusts its position on the outer wall of the rotating rod 103. Then make the vacuum suction cup 106 fit with the installation point, and start the vacuum pump 107 to evacuate the air between the two, so that the inside of the vacuum suction cup 106 is in a negative pressure state, improving the adsorption of the structure; while improving the installation effect of the device, the compatibility of the structure installation is also improved.

[0050] Start the first motor 206 to rotate a number of photovoltaic panel bodies 402 for light source access. When the light source is in the west setting state, start the second motor 207 to drive the photovoltaic panel body 402 to rotate, and then drive the photovoltaic panel body 402 to adjust the angle through the first motor 206 again, improving the light source access effect while improving the compatibility of the angle adjustment; start the third electric push rod 406 to push the cleaning plate body 409 up to clean the surface of the photovoltaic panel body 402, avoiding the problem that the light source access is not in place due to impurity residue, and improving the cleaning effect of the device.
