Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic module construction, and specifically provides a solar photovoltaic module and a construction method for pouring its base platform. Background Art

[0002] Solar photovoltaics, also known as a solar photovoltaic system, refers to a facility that converts solar energy into direct current electricity using the photovoltaic effect of photovoltaic semiconductor materials. The semiconductor materials mainly used for power generation include: monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, etc. The main components of a solar photovoltaic system include solar cell modules, controllers, inverters, and storage batteries.

[0003] The solar cell module is the core part of the system, responsible for converting solar light energy into electrical energy. The controller is used to manage the charging and discharging process of the storage battery to ensure the stable operation of the system. The inverter converts direct current into alternating current to meet the needs of various loads. The storage battery is used to store electrical energy to ensure that the system can still operate normally when there is no sunlight.

[0004] However, during the construction of solar photovoltaic modules, the construction method of the module brackets is relatively cumbersome and time-consuming, resulting in a reduction in the construction efficiency of the photovoltaic modules. Therefore, it does not meet the existing requirements, and for this reason, we propose a solar photovoltaic module and a construction method for pouring its base platform. Summary of the Invention

The top end of the connecting ball rod is spherical, and an adjustable locking plate is rotatably installed on the outer side of the top end of the connecting ball rod. Through holes are provided at the four end corners of the adjustable locking plate. The adjustable locking plate is connected to the photovoltaic panel protection metal frame by screws.

[0008] Preferably, a storage splicing plate is fixed on the outer surface of the support rod. The photovoltaic panel support frames are spliced and stored through the storage splicing plate.

[0009] Preferably, the storage splicing plate includes a fixing plate. One side of the fixing plate is fixed to the outer side of the support rod. The other side of the fixing plate is fixed with a docking strip. A T-shaped card slot is provided on one side surface of the docking strip. A T-shaped card connection plate is fixed on one side of the side where the fixing plate is connected to the docking strip.

[0010] Preferably, the support base includes a base. A ring plate is fixed on the outer side of the base. A positioning sleeve rod is fixed to the top end of the base. A square groove is provided at the top end of the positioning sleeve rod. The bottom end of the support rod is inserted inside the square groove.

[0011] Preferably, four positioning holes are provided on the outer surface of the top end of the positioning sleeve rod. A fastening screw is inserted into the positioning hole. The threaded end of the fastening screw is screwed into the assembly screw hole through threads.

[0012] Preferably, a through casting hole is provided on the outer surface of the bottom end of the positioning sleeve rod. A rubber sleeve is provided inside the base. The inside of the rubber sleeve is hollow and a round hole is provided at the top end. A docking sleeve is fixed on the outer side of the round hole. The docking sleeve is inserted into the bottom end of the positioning sleeve rod, and through holes are provided on the outer side of the docking sleeve. The positions of the holes are aligned with the casting hole and their axes coincide with each other.

[0013] Preferably, a plurality of groups of guiding inclined holes are provided on the outer surface of the ring plate and are distributed in a circular array around its center. Each group of guiding inclined holes has two and their positions are symmetrically arranged up and down. A plurality of sliding blocks are slidably installed inside the ring plate. The sliding blocks are distributed in a circular array around the axis of the base. A reinforcing inclined insertion rod is slidably installed inside the guiding inclined hole. One end of the reinforcing inclined insertion rod contacts the sliding block.

[0014] Preferably, a plurality of moving blocks are provided on the outer side of the rubber sleeve. The moving blocks are distributed in a circular array around the axis of the rubber sleeve. An elastic connection bar is fixed between two adjacent moving blocks. A guiding push rod is fixed on the outer surface of the moving block. The guiding push rod penetrates through the base and is slidably inserted into the inner part of the ring plate.

[0015] Preferably, the reinforcing inclined insertion rod includes two symmetrically distributed splicing rods. One end of each splicing rod is fixed with a contact ball end. The contact ball end is hemispherical and contacts with the sliding block. A guiding inclined surface is provided on the inner side of the other end of each splicing rod. When the two symmetric splicing rods are fitted together, the guiding inclined surfaces at the ends form a V-shaped notch.

[0016] A construction method for pouring the base of a solar photovoltaic module includes the following steps:

[0017] S1: First, four symmetrically located and uniformly deep holes are dug at the installation site of the photovoltaic panel assembly. The diameter of this hole is the same as the diameter of the ring plate;

[0018] S2: Place the bracket base into the dug hole, and dock the concrete pouring pipe with the pouring hole at the bottom of the positioning sleeve rod;

[0019] S3: Pour concrete into the docking sleeve and the rubber sleeve through the pouring hole. After the concrete is poured, the rubber sleeve expands;

[0020] S4: The expanded rubber sleeve pushes the moving block and the guiding push rod to move. The guiding push rod enters the inner part of the ring plate and pushes the sliding block to slide. The sliding block pushes the reinforcing inclined insertion rod out of the guiding inclined hole and obliquely inserts it into the soil;

[0021] S5: After the concrete filling in the rubber sleeve is completed, backfill the hole with the excavated soil;

[0022] S6: After the hole is backfilled, dock the bottom end of the support rod with the positioning sleeve rod, and use fastening screws to fix the positioning sleeve rod and the support rod;

[0023] S7: According to the installation angle of the photovoltaic panel assembly, adjust the height position and the inclination angle of the four adjustable locking plates;

[0024] S8: After the height and the inclination angle of the adjustable locking plate are adjusted, use the limit screw to lock the adjustable connecting rod;

[0025] S9: Finally, install and fix the photovoltaic panel assembly with the four adjustable locking plates whose angles have been adjusted.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the present invention, concrete is poured into the rubber sleeve to cause the rubber sleeve to expand. After expansion, the rubber sleeve presses against the sliding block through the moving block and the guiding push rod, causing the sliding block to push the reinforcing inclined inserted rod to extend from the guiding inclined hole and be obliquely inserted into the soil layer, thereby increasing the stability and connection strength between the support base and the soil layer and ensuring the stability of the solar photovoltaic module base after construction.

[0028] 2. In the present invention, guiding inclined surfaces are provided inside the ends of two symmetrical splicing rods, and the two guiding inclined surfaces form a V-shaped notch, causing the two splicing rods to incline and move away from each other after entering the soil, so that the reinforcing inclined inserted rod bifurcates and unfolds in a V shape in the soil, better increasing the connection strength between the ring plate and the soil layer and further ensuring the stability of the solar photovoltaic module base after construction.

[0029] 3. In the present invention, the T-shaped clamping plate on the outside of one support rod is slidably inserted into the T-shaped clamping groove on the side of the docking strip on the outside of the other support rod, enabling the rapid mutual splicing and assembly of four photovoltaic panel support frames without the need to use other tools to bind the photovoltaic panel support frames, facilitating the storage and handling of the photovoltaic panel support frames. Moreover, the four photovoltaic panel support frames are spliced into a group. During construction, only the corresponding number of groups of spliced bodies of the photovoltaic panel support frames needs to be selected according to the number of photovoltaic panel components, without the need to separately confirm the number of photovoltaic panel support frames, which is convenient for construction.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0042] As Figure 1 and Figure 2 shown, a solar photovoltaic module includes a photovoltaic panel assembly 1, a controller, an inverter, and a storage battery. The photovoltaic panel assembly 1 is connected to the controller, the inverter, and the storage 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 plate 104. The upper surface of the solar energy conversion plate 104 is fixed with a sunlight receiving plate 103. The upper surface of the sunlight receiving plate 103 is covered with a layer of transparent protective film 102.

[0043] As Figure 1 , Figure 3 and Figure 4As shown, photovoltaic panel support frames 2 are detachably installed at the bottoms of the four end corners of the photovoltaic panel protection metal frame 101. A support base 3 is detachably installed at the bottom end of the photovoltaic panel support frame 2. The photovoltaic panel support frame 2 includes a support rod 201. Assembly screw holes 206 are provided on the four side surfaces at the bottom end of the support rod 201. An adjustable connecting rod 202 is slidably inserted into the top end of the support rod 201. A limit screw 203 is installed on the front surface of the top end of the support rod 2 in a threaded manner. The threaded end of the limit screw 203 penetrates through the support rod 201 and contacts the adjustable connecting rod 202. A connecting ball rod 205 is fixed to the top end of the adjustable connecting rod 202. The top end of the connecting ball rod 205 is spherical, and an adjustable locking plate 204 is rotatably installed on the outer side of the top end of the connecting ball rod 205. Through holes are provided at the four end corners of the adjustable locking plate 204. The adjustable locking plate 204 is connected to the photovoltaic panel protection metal frame 101 by screws. By pulling the adjustable connecting rod 202, the height of the adjustable locking plate 204 can be adjusted, so as to adjust the heights of the four adjustable locking plates 204 according to the installation angle of the photovoltaic panel assembly 1, so that the photovoltaic panel assembly 1 can better receive sunlight and convert it into electrical energy.

[0044] As Figures 7 to 10 shown, the support base 3 includes a base 301. A ring plate 302 is fixed to the outside of the base 301. A positioning sleeve rod 304 is fixed to the top end of the base 301. A square groove is provided at the top end of the positioning sleeve rod 304. The bottom end of the support rod 201 is inserted into the inner side of the square groove. Four positioning holes 305 are provided on the outer surface of the top end of the positioning sleeve rod 304. A fastening screw 306 is inserted into the positioning hole 305. The threaded end of the fastening screw 306 is screwed into the inner side of the assembly screw hole 206 through threads. The support rod 201 and the positioning sleeve rod 304 are connected and fixed by the fastening screw 306 to ensure the structural stability of the support rod 201 and support the photovoltaic panel assembly 1.

[0045] A through casting hole 307 is provided on the outer surface of the bottom end of the positioning sleeve rod 304. A rubber sleeve 310 is provided inside the base 301. The inside of the rubber sleeve 310 is hollow and a round hole is provided at the top end. A butt joint sleeve 309 is fixed to the outside of the round hole. The butt joint sleeve 309 is inserted into the bottom end of the positioning sleeve rod 304, and through holes are provided on the outer side of the butt joint sleeve 309. The holes are aligned with the casting hole 307 in position and their axes coincide with each other. Concrete is poured into the rubber sleeve 310 through the casting hole 307 and the holes, so that the rubber sleeve 310 expands and fills the inside of the base 301, increasing the weight of the base 301 and ensuring the resistance of the photovoltaic panel assembly 1 to external wind force after installation.

[0046] The outer surface of the ring plate 302 is provided with multiple groups of guiding inclined holes 303 that are circularly arrayed around its center. Each group of guiding inclined holes 303 has two and their positions are symmetrically up and down. A plurality of sliding blocks 314 are slidably installed inside the ring plate 302. The sliding blocks 314 are circularly arrayed around the axis of the base 301. A reinforcing inclined insertion rod 308 is slidably installed inside the guiding inclined hole 303. One end of the reinforcing inclined insertion rod 308 contacts the sliding block 314. A plurality of moving blocks 311 are provided on the outer side of the rubber sleeve 310. The moving blocks 311 are circularly arrayed around the axis of the rubber sleeve 310. An elastic connecting strip 312 is fixed between two adjacent moving blocks 311. A guiding push rod 313 is fixed on the outer surface of the moving block 311. The guiding push rod 313 penetrates through the base 301 and is slidably inserted inside the ring plate 302. After the inside of the rubber sleeve 310 is filled with concrete and expands, the moving block 311 is pushed by the expanded rubber sleeve 310. At this time, the moving block 311 pushes the guiding push rod 313 into the inside of the ring plate 302, so that the guiding push rod 313 pushes the sliding block 314 to slide and extrudes the reinforcing inclined insertion rod 308, causing the reinforcing inclined insertion rod 308 to obliquely insert into the soil, increasing the connection strength between the ring plate 302 and the soil layer, and ensuring the stability of the overall bracket base 3 after pouring concrete.

[0047] The reinforcing inclined 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. The inner side of the other end of the splicing rod 3081 is provided with a guiding inclined surface 3082. When the two symmetric splicing rods 3081 are fitted, the guiding inclined surfaces 3082 at the ends form a V-shaped notch. The V-shaped notch formed by the guiding inclined surfaces 3082 at the ends of the two splicing rods 3081 causes the two splicing rods 3081 to separate from each other when they extend out of the guiding inclined hole 303 and contact the soil. This makes the reinforcing inclined insertion rod 308 fork and expand in a V shape in the soil, further increasing the structural stability of the base 301 and the ring plate 302 after construction.

[0048] Such as Figure 5 And Figure 6As shown in the figure, a storage splicing plate 4 is fixed on the outer surface of the support rod 201. The photovoltaic panel support frames 2 are spliced and stored through the storage splicing plate 4. The storage splicing plate 4 includes a fixed plate 401. One side of the fixed plate 401 is fixed to the outside of the support rod 201, and a docking strip 403 is fixed to the other side of the fixed plate 401. A T-shaped card slot 404 is formed on one side surface of the docking strip 403. A T-shaped clamping plate 402 is fixed to the side of the fixed plate 401 connected to the docking strip 403. By sliding and inserting the T-shaped clamping plate 402 on the outside of one support rod 201 into the T-shaped card slot 404 on the side surface of the docking strip 403 on the outside of another support rod 201, the mutual splicing and assembly of the four photovoltaic panel support frames 2 can be quickly realized without using other tools to bind the photovoltaic panel support frames 2, which is convenient for the storage and handling of the photovoltaic panel support frames 2. The four photovoltaic panel support frames 2 are spliced into a set of splicing bodies through the storage splicing plate 4. During construction, only the corresponding number of sets of photovoltaic panel support frame 2 splicing bodies needs to be selected according to the number of photovoltaic panel assemblies 1, without separately confirming the number of photovoltaic panel support frames 2, which is convenient for construction.

[0049] First, four symmetrically positioned pits with the same depth and diameter are dug at the installation position of the photovoltaic panel assembly 1. The base 301 and the ring plate 302 are placed in the pits. 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 pit. Then, the concrete perfusion pipe is docked with the pouring hole 307, and after docking, concrete is poured into the pouring hole 307 through the concrete perfusion pipe.

[0050] When pouring concrete, the concrete enters the inside of the docking sleeve 309 through the holes on the outside of the docking sleeve 309 and enters the inside of the rubber sleeve 310 through the round hole at the top of the rubber sleeve 310. The rubber sleeve 310 gradually expands as the concrete inside is poured. The expanded rubber sleeve 310 squeezes the moving block 311 into the inside of the base 301. At the same time, the elastic connection strip 312 is elastically stretched. At the same time, the moving block 311 pushes the guiding push rod 313 into the inside of the ring plate 302. The end of the guiding push rod 313 that enters the inside of the ring plate 302 squeezes the sliding block 314. At this time, the sliding block 314 is pushed by the guiding push rod 313 and slides inside the ring plate 302. The sliding sliding block 314 pushes the reinforcing inclined insertion rod 308 and makes the reinforcing inclined insertion rod 308 extend out from the guiding inclined hole 303.

[0051] After the reinforcing inclined insertion rod 308 extends out of the guiding inclined hole 303, it contacts the inner wall of the pit and inserts into the soil layer of the pit. When the reinforcing inclined insertion rod 308 is inserted into the soil layer, the soil will enter the V-shaped notch formed by the guiding inclined surfaces 3082 on the inner sides of the ends of the two mutually fitting splicing rods 3081. As the soil continuously enters, the gap between the ends of the two splicing rods 3081 will gradually increase, causing the two splicing rods 3081 to tilt and move laterally. Thus, after the reinforcing inclined insertion rod 308 extends out of the guiding inclined hole 303 and enters the soil layer, the reinforcing inclined insertion rod 308 bifurcates into a V shape in the soil, and the inserted and bifurcated reinforcing inclined insertion rod 308 is used to increase the connection strength between the ring plate 302 and the inner wall of the pit;

[0052] After the concrete is poured inside the rubber sleeve 310, the bottom end of the support rod 201 is docked with the positioning sleeve rod 304 and fixed by the fastening screw 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, only need to pull the adjustable connecting rod 202 to slide out or retract at 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 of the adjustable locking plate 204 is adjusted, 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 time, and effectively improves the construction efficiency of the solar photovoltaic module.

[0053] A construction method for pouring the base of a solar photovoltaic module includes the following steps:

[0054] S1: First, dig four pits with symmetrical positions and the same depth at the installation location of the photovoltaic panel assembly 1. The diameter of this pit is the same as the diameter of the ring plate 302;

[0055] S2: Place the bracket base 3 into the dug pit, and dock the concrete pouring pipe with the pouring hole 307 at the bottom end of the positioning sleeve rod 304;

[0056] S3: Pour concrete into the docking sleeve 309 and the rubber sleeve 310 through the pouring hole 307. After the concrete is poured, the rubber sleeve 310 expands;

[0057] S4: The expanded rubber sleeve 310 pushes the moving block 311 and the guiding push rod 313 to move. The guiding push rod 313 enters the inside of the ring plate 302 and pushes the sliding block 314 to slide. The sliding block 314 pushes the reinforcing inclined insertion rod 308 out of the guiding inclined hole 303 and obliquely inserts it into the soil;

[0058] S5: After the concrete is filled inside the rubber sleeve 310, backfill the pit with the excavated soil;

[0059] S6: After the pit is backfilled, dock the bottom end of the support rod 201 with the positioning sleeve rod 304, and use the fastening screw 306 to fix the positioning sleeve rod 304 and the support rod 201;

[0060] S7: According to the installation angle of the photovoltaic panel assembly 1, adjust the height position and tilt angle of the four adjustable locking plates 204;

[0061] S8: After the height and tilt angle of the adjustable locking plate 204 are adjusted, lock the adjustable link 202 with the limit screw 203;

[0062] S9: Finally, install and fix the photovoltaic panel assembly 1 with the four adjustable locking plates 204 whose angles have been adjusted.

[0063] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
