DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figure 1 and Figure 2 As shown, a solar photovoltaic module includes a photovoltaic panel assembly 1, a controller, an inverter and a battery. The photovoltaic panel assembly 1 is connected to the controller, the inverter and the battery through wires. The photovoltaic panel assembly 1 includes a photovoltaic panel protection metal frame 101. The inner side of the photovoltaic panel protection metal frame 101 is inlaid with a solar energy conversion panel 104. The upper surface of the solar energy conversion panel 104 is fixed with a sunlight receiving panel 103. The upper surface of the sunlight receiving panel 103 is covered with a layer of transparent protective film 102.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the photovoltaic panel protection metal frame 101 has photovoltaic panel support frames 2 detachably mounted on the bottom of the four end corners, and the bottom of the photovoltaic panel support frame 2 has a bracket base 3 detachably mounted thereon. The photovoltaic panel support frame 2 includes a support rod 201, and the four sides of the bottom end of the support rod 201 are provided with assembly screw holes 206. The top end of the support rod 201 is slidably plugged with an adjustable connecting rod 202. The top front surface of the support rod 201 is threadedly mounted with a limit screw 203. The threaded end of the limit screw 203 penetrates the support rod 201 and contacts with the adjustable connecting rod 202. A connecting ball rod 205 is fixed at the top, and the top of the connecting ball rod 205 is a sphere, and an adjustable locking plate 204 is rotatably installed on the outer side of the top of the connecting ball rod 205. The four end corners of the adjustable locking plate 204 are provided with through holes. The adjustable locking plate 204 is connected to the photovoltaic panel protection metal frame 101 by screws. The height of the adjustable locking plate 204 can be adjusted by pulling the adjustable connecting rod 202, so that the height of the four adjustable locking plates 204 can be adjusted according to the installation angle of the photovoltaic panel assembly 1, so that the photovoltaic panel assembly 1 can better receive sunlight and convert electrical energy.

[0023] like Figures 7 to 10 As shown, the bracket base 3 includes a base 301, a ring plate 302 is fixed on the outer side of the base 301, a positioning sleeve rod 304 is fixed on the top of the base 301, a square groove is opened on the top of the positioning sleeve rod 304, the bottom end of the support rod 201 is inserted into the inner side of the square groove, and four positioning holes 305 are arranged on the outer surface of the top end of the positioning sleeve rod 304, and fastening screws 306 are inserted in the positioning holes 305. The threaded end of the fastening screw 306 is screwed into the inner side of the assembly screw hole 206 through the thread, and the support rod 201 and the positioning sleeve rod 304 are connected and fixed by the fastening screw 306, so as to ensure the structural stability of the support rod 201 and support the photovoltaic panel assembly 1.

[0024] A through casting hole 307 is provided on the outer surface of the bottom end of the positioning sleeve rod 304, and a rubber sleeve 310 is provided inside the base 301. The rubber sleeve 310 is hollow inside and has a round hole on the top. A docking sleeve 309 is fixed on the outside of the round hole. The docking sleeve 309 is inserted into the bottom end of the positioning sleeve rod 304, and a through hole is provided on the outside of the docking sleeve 309. The hole is aligned with the casting hole 307 and the axes coincide with each other. Concrete is poured into the rubber sleeve 310 using the casting hole 307 and the hole, so that the rubber sleeve 310 expands and fills the inside of the base 301, thereby increasing the weight of the base 301 and ensuring the resistance of the photovoltaic panel assembly 1 to external wind force after installation.

[0025] The outer surface of the ring plate 302 is provided with a plurality of groups of guide inclined holes 303 distributed in a circular array around the center of the circle, and each group of guide inclined holes 303 has two and the positions are symmetrical up and down. A plurality of sliding blocks 314 are slidably installed inside the ring plate 302, and the sliding blocks 314 are distributed in a circular array around the axis of the base 301. A reinforcement oblique insertion rod 308 is slidably installed on the inner side of the guide oblique hole 303, and one end of the reinforcement oblique insertion rod 308 is in contact with the sliding block 314. A plurality of moving blocks 311 are provided on the outer side of the rubber sleeve 310, and the moving blocks 311 are distributed in a circular array around the axis of the rubber sleeve 310. An elastic connection is fixed between two adjacent moving blocks 311. The connecting strip 312 and the outer surface of the movable block 311 are fixed with a guide push rod 313, which passes through the base 301 and is slidably inserted into the ring plate 302. After the rubber sleeve 310 is filled with concrete and expands, the movable block 311 is pushed by the expanded rubber sleeve 310. At this time, the movable block 311 pushes the guide push rod 313 into the ring plate 302, so that the guide push rod 313 pushes the sliding block 314 to slide and squeeze the reinforcement oblique insertion rod 308, so that the reinforcement oblique insertion rod 308 is inserted obliquely into the soil, thereby increasing the connection strength between the ring plate 302 and the soil layer, and ensuring the stability of the bracket base 3 after the overall concrete is poured.

[0026] The reinforcement oblique insertion rod 308 includes two symmetrically distributed splicing rods 3081, one end of the splicing rod 3081 is fixed with a contact ball end 3083, the contact ball end 3083 is hemispherical and contacts the sliding block 314, and the other end of the splicing rod 3081 is provided with a guide slope 3082 on the inner side. When the two symmetrical splicing rods 3081 are fitted together, the guide slopes 3082 at the ends form a V-shaped notch. The V-shaped notch formed by the guide slopes 3082 at the ends of the two splicing rods 3081 makes it possible for the two splicing rods 3081 to extend from the guide inclined holes 303 and contact the soil. The ends of the two splicing rods 3081 are separated from each other due to the contact between the guide slopes 3082 and the soil, so that the reinforcement oblique insertion rod 308 is forked in the soil and spread out in a V shape, further increasing the structural stability of the base 301 and the ring plate 302 after construction.

[0027] like Figure 5 and Figure 6As shown, a receiving splicing plate 4 is fixed on the outer surface of the support rod 201, and the photovoltaic panel support frame 2 and the photovoltaic panel support frame 2 are spliced ​​and received through the receiving splicing plate 4. The receiving splicing plate 4 includes a fixing plate 401, one side of the fixing plate 401 is fixed to the outer side of the support rod 201, and the other side of the fixing plate 401 is fixed with a docking strip 403, and one side surface of the docking strip 403 is provided with a T-shaped card groove 404, and a T-shaped card plate 402 is fixed on one side of the side where the fixing plate 401 and the docking strip 403 are connected. 02 is slidably inserted into the T-shaped slot 404 on the side of the docking strip 403 on the outside of another support rod 201, so that four photovoltaic panel support frames 2 can be quickly spliced ​​and assembled with each other, without the need to use other tools to restrain the photovoltaic panel support frames 2, which is convenient for storing and carrying the photovoltaic panel support frames 2. The four photovoltaic panel support frames 2 are spliced ​​into a group of splicing bodies through the storage splicing plate 4. During construction, only the corresponding number of photovoltaic panel support frame 2 splicing bodies need to be selected according to the number of photovoltaic panel assemblies 1. There is no need to confirm the number of photovoltaic panel support frames 2 separately, which is convenient for construction.

[0028] First, four symmetrical holes with uniform depth and diameter are dug at the installation location of the photovoltaic panel assembly 1, and the base 301 and the ring plate 302 are placed in the holes. At this time, the upper surface of the base 301 is flush with the ground, and the outer surface of the ring plate 302 is in contact with the inner wall of the hole. At this time, the pipe for pouring concrete is connected with the pouring hole 307, and after the connection, concrete is poured into the pouring hole 307 through the concrete pouring pipe; When the concrete is poured, the concrete enters the docking sleeve 309 through the hole on the outside of the docking sleeve 309 and enters the rubber sleeve 310 through the round hole on the top of the rubber sleeve 310. The rubber sleeve 310 gradually expands as the internal concrete is poured. The expanded rubber sleeve 310 squeezes the moving block 311 toward the inside of the base 301. At the same time, the elastic connecting strip 312 is elastically stretched. At the same time, the moving block 311 pushes the guide push rod 313 into the ring plate 302. The end of the guide push rod 313 entering the ring plate 302 squeezes the sliding block 314. At this time, the sliding block 314 is pushed by the guide push rod 313 and slides inside the ring plate 302. The sliding sliding block 314 pushes the reinforcement oblique insertion rod 308 and makes the reinforcement oblique insertion rod 308 extend from the guide oblique hole 303. After extending out of the guide inclined hole 303, the reinforcement oblique insertion rod 308 contacts the inner wall of the pit and is inserted into the soil layer of the pit. When the reinforcement oblique insertion rod 308 is inserted into the soil layer, the soil will enter the V-shaped gap formed by the guide inclined surfaces 3082 on the inner sides of the ends of the two splicing rods 3081 that fit each other. As the soil continues to enter, the gap between the ends of the two splicing rods 3081 will gradually increase, causing the two splicing rods 3081 to tilt and move sideways, so that after the reinforcement oblique insertion rod 308 extends out of the guide inclined hole 303 and enters the soil layer, the reinforcement oblique insertion rod 308 is forked in the soil and unfolded in a V shape, and the connection strength between the ring plate 302 and the inner wall of the pit is increased by using the reinforcement oblique insertion rod 308 inserted into the soil layer and forked; After the concrete inside the rubber sleeve 310 is poured, the bottom end of the support rod 201 is connected to the positioning sleeve rod 304 and fixed by fastening screws 306. At this time, the height and inclination angle of the four adjustable locking plates 204 are adjusted according to the installation angle of the photovoltaic panel assembly 1. When adjusting, it is only necessary to pull the adjustable connecting rod 202 to slide out or retract on the top of the support rod 201 and push the adjustable locking plate 204 to rotate on the outside of the connecting ball rod 205. After the height adjustment of the adjustable locking plate 204 is completed, the adjustable connecting rod 202 is squeezed and locked by the limit screw 203 to ensure that the adjustable connecting rod 202 cannot slide along the axial direction. Finally, the photovoltaic panel assembly 1 is locked with the adjustable locking plate 204 by screws, which simplifies the construction method of the solar photovoltaic module, shortens the construction implementation, and effectively improves the construction efficiency of the solar photovoltaic module.

[0029] A method for pouring a base of a solar photovoltaic module comprises the following steps: S1: First, four symmetrically positioned and uniformly deep pits are dug at the installation site of the photovoltaic panel assembly 1, and the diameter of the pits is consistent with the diameter of the ring plate 302; S2: Place the support base 3 into the excavated pit, and connect the concrete pouring pipe to the pouring hole 307 at the bottom end of the positioning sleeve rod 304; S3: pouring concrete into the butt sleeve 309 and the rubber sleeve 310 through the pouring hole 307, and the rubber sleeve 310 expands after the concrete is poured; S4: The expanded rubber sleeve 310 pushes the moving block 311 and the guide push rod 313 to move, the guide push rod 313 enters the ring plate 302 and pushes the sliding block 314 to slide, and the sliding block 314 pushes the reinforcement oblique insertion rod 308 out of the guide oblique hole 303 and inserts it obliquely into the soil; S5: After the concrete filling inside the rubber sleeve 310 is completed, the hole is backfilled with the excavated soil; S6: After the pit is backfilled, the bottom end of the support rod 201 is butted against the positioning sleeve rod 304, and the positioning sleeve rod 304 is fixed to the support rod 201 using the fastening screws 306; S7: adjusting the height position and tilt angle of the four adjustable locking plates 204 according to the installation angle of the photovoltaic panel assembly 1; S8: After the height and tilt angle of the adjustable locking plate 204 are adjusted, the adjustable connecting rod 202 is locked by the limit screw 203; S9: Finally, the photovoltaic panel assembly 1 and the adjustable locking plate 204 with four angles adjusted are installed and fixed.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
