DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings:

[0033] Embodiment 1:

[0034] As attached Figure 1 To Attachment Figure 8 As shown:

[0035] The present invention provides a big data intelligent floating photovoltaic power generation platform, which structure includes a base 1, a bracket 2, and a solar panel 3. The bottom of the bracket 2 is welded to the top of the base 1, and the bottom of the solar panel 3 is fixed to the top of the bracket 2.

[0036] The solar panel 3 includes a panel body 31 , a battery 32 , and a conductive wire 33 . The battery 32 is mounted on the surface of the panel body 31 , and two ends of the conductive wire 33 are connected between the battery 32 .

[0037] The battery 32 comprises a protective box 321, a top cover 322, a cell body 323, a collecting mechanism 324 and heat dissipation holes 325. The top cover 322 is movably engaged with the top of the protective box 321. The cell body 323 is installed inside the left side of the protective box 321. The collecting mechanism 324 is arranged on the right side of the cell body 323. The heat dissipation holes 325 penetrate between the right side surface and the inner wall of the protective box 321. The cell body 323 is connected to the solar panel 3 through a conductive wire 33. The electric energy generated by the solar panel 3 is transmitted to the cell body 323 for storage through the conductive wire 33. The protective box 321 is a square metal box as a whole, which can cooperate with the collecting mechanism 324 to generate suction through magnetic activity to limit the collecting mechanism 324.

[0038] Among them, the collecting mechanism 324 includes a first support plate 24a, a drainage pipe 24b, a water storage pipe 24c, and a pipe groove 24d. The left end of the drainage pipe 24b is movably engaged with the right surface of the first support plate 24a. The pipe groove 24d is arranged at the inner bottom of the first support plate 24a. The top of the water storage pipe 24c is movably matched with the pipe groove 24d. The first support plate 24a is a rectangular plate with magnetism as a whole, and the interior is a hollow structure, which is conducive to rainwater entering the first support plate 24a for collection. The inner wall of the pipe groove 24d is threaded, and the water storage pipe 24c and the pipe groove 24d are installed by threaded movability, which is conducive to disassembly of the water storage pipe 24c and cleaning of impurities inside the water storage pipe 24c, thereby increasing the volume inside the water storage pipe 24c. The bottom end of the water storage pipe 24c passes through the inner bottom of the protection box 321, which is conducive to the discharge of rainwater in the water storage pipe 24c to the outside of the protection box 321.

[0039] Among them, the drainage tube 24b includes a first tube body b1, a contact plate b2, and a blocking plate b3. The contact plate b2 is fixed at the bottom of the right end of the first tube body b1, and the blocking plate b3 is arranged inside the first tube body b1. The first tube body b1 is provided with a raised semicircular block on the inner wall near the right end, which is conducive to the active cooperation between the raised block and the blocking plate b3 and limits the blocking plate b3. The overall diameter of the blocking plate b3 is the same as the diameter of the inner wall of the first tube body b1, which is conducive to the blocking plate b3 being stuck inside the first tube body b1 and reducing the phenomenon of the blocking plate b3 detaching from the inner wall of the first tube body b1.

[0040] Among them, the water storage pipe 24c includes a second tube body c1, a sleeve c2, and a bottom cover c3. The bottom end of the sleeve c2 is connected to the top surface of the second tube body c1 as a whole. The bottom cover c3 is movably engaged with the bottom of the second tube body c1. The second tube body c1 is a circular metal tube as a whole, which can cooperate with the bottom cover c3 through magnetic force to fix the bottom cover c3. When the thrust of rainwater reaches a certain force, the bottom cover c3 is pushed down and opened to discharge the rainwater inside the second tube body c1.

[0041] Among them, the bottom cover c3 includes a cover body c31, a telescopic strip c32, and a ring c33. The bottom end of the telescopic strip c32 is fixed to the upper surface of the cover body c31 close to the left and right sides, and the ring c33 is nested outside the cover body c31. The top of the telescopic strip c32 is connected to the inner wall of the bottom end of the second tube body c1, and the whole is made of rubber material, which is elastic, which is conducive to generating tension through the telescopic strip c32 as the bottom cover c3 deforms and expands, and pulling the bottom cover c3 to reset. The ring c33 is a magnetic ring as a whole, and the bottom cover c3 is limited by the ring c33 and the second tube body c1 through magnetic activity.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In the present invention, the power generation platform is placed on the sea level, the base 1 floats on the water surface due to the buoyancy of the sea water, the sunlight is irradiated on the solar panel 3, the solar panel 3 absorbs the sunlight and converts it into electrical energy, which is then transmitted to the cell body 323 of the storage battery 32 through the conductive wire 33 for storage, and the rainwater flows into the heat dissipation hole 325 of the protection box 321 due to the wind force, and flows along the inner wall of the protection box 321, and the rainwater flows along the drainage pipe 24b of the collection mechanism 324. The rain flows into the first tube b1, passes into the first support plate 24a and enters the water storage pipe 24c, collects the rain in the water storage pipe 24c, and reduces the accumulation of rain in the protection box 321. As the amount of rain in the second tube c1 increases, the thrust of the rain increases, pushing the cover c31 of the bottom cover c3 toward the outside of the water storage pipe 24c. When the bottom cover c3 moves, the cover c31 pulls the telescopic strip c32 to expand. When the cover c3 is separated from the bottom of the water storage pipe 24c, the cover c31 is pulled to expand the telescopic strip c32. When the rainwater in the water storage pipe 24c is discharged, the retractable strip c32 is reset to pull the bottom cover c3 to reset, so that the bottom cover c3 enters the bottom of the water storage pipe 24c, so that the water storage pipe 24c is sealed, and the ring c33 and the second tube body c1 are limited by magnetic activity. After a period of time, the top cover 322 is opened, the collecting mechanism 324 is taken out, and the water storage pipe 24c is rotated and removed to clean the impurities in the water storage pipe 24c, reduce the accumulation of impurities in the water storage pipe 24c, and increase the volume of the water storage pipe 24c. After cleaning, the water storage pipe 24c is put back to the bottom of the first support plate 24a, and the sleeve c2 is threadedly connected to the pipe groove 24d to fix the water storage pipe 24c at the bottom of the first support plate 24a. Then the collecting mechanism 324 is installed in the protective box 321 and reset, and the platform is connected to the APP to monitor the power of the battery 32 in real time.

[0044] Embodiment 2:

[0045] As attached Fig. 9 To Attachment Fig.13 As shown:

[0046] Among them, the blocking plate b3 includes a second support plate b31, a drainage hole b32, a connecting pipe b33, a blocking ball b34, and a block b35. The drainage hole b32 runs through the upper and lower surfaces of the middle part of the second support plate b31. The top of the connecting pipe b33 is movably engaged with the bottom of the drainage hole b32. The blocking ball b34 is placed inside the drainage hole b32. The block b35 is embedded in the inner wall of the lower middle part of the drainage hole b32 and movably cooperates with the blocking ball b34. The diameter of the top of the drainage hole b32 is smaller than that of the bottom, and can movably cooperate with the blocking ball b34 to limit the blocking ball b34. The diameter of the connecting pipe b33 is larger than that of the blocking ball b34, which is beneficial for the blocking ball b34 to move to the inside of the connecting pipe b33. There is a gap between the connecting pipe b33 and the blocking ball b34, which is beneficial for rainwater to be discharged along the gap.

[0047] Among them, the blocking ball b34 includes a first sphere e1, an expansion plate e2, and an elastic bar e3. The expansion plate e2 is sleeved on the outside of the first sphere e1, and the two ends of the elastic bar e3 are fixed between the outer wall of the first sphere e1 and the inner surface of the expansion plate e2. The expansion plate e2 is composed of two semicircular plates, so that the expansion plate e2 moves to the left and right sides respectively and sticks to the inner wall of the drainage hole b32, thereby reducing the gap between the inner wall of the drainage hole b32 and the blocking ball b34, and reducing the phenomenon of rainwater flowing back and overflowing along the drainage hole b32. The first sphere e1 is a sponge ball as a whole, which has buoyancy, which is conducive to the first sphere e1 moving up and down as the buoyancy changes due to the rise and fall of the liquid level.

[0048] Among them, the first sphere e1 includes a second sphere e11, a matching cover e12, and a movable ball e13. The bottom of the matching cover e12 is movably engaged with the top of the second sphere e11. The movable ball e13 is arranged inside the second sphere e11. The movable ball e13 is a rubber ball as a whole, and there are eight of them. It has elasticity, which is conducive to increasing the power generated by the up and down jumping of the movable ball e13, so that the shaking power of the blocking ball b34 is increased, which is conducive to the shaking and falling of impurities attached to the outer wall of the blocking ball b34, so that the blocking ball b34 can be tightly attached to the inner wall of the drainage hole b32.

[0049] The specific usage and function of this embodiment are as follows:

[0050] In the present invention, when rainwater in the protection box 321 flows into the drainage pipe 24b, the rainwater passes through the drainage hole b32 of the blocking plate b3, and the blocking ball b34 in the drainage hole b32 moves downward under the driving force of the rainwater, and the blocking ball b34 cooperates with the block b35 on the inner wall of the connecting pipe b33 to limit the position, and a gap appears between the blocking ball b34 and the inside of the connecting pipe b33, and the rainwater passes through the gap and is discharged into the water storage pipe 24c along the connecting pipe b33. When the drainage speed in the water storage pipe 24c slows down, the rainwater gradually increases and flows back into the drainage pipe 24b, blocking the inner wall of the connecting pipe b33. The first sphere e1 of the blocking ball b34 moves toward the top of the drainage hole b32 under the buoyancy of the liquid, and at the same time, the elastic bar e3 pushes the expansion plate e2, so that the expansion plate e2 sticks to the inner wall of the drainage hole b32. The blocking ball b34 blocks the rainwater and reduces the backflow and overflow of rainwater along the drainage pipe 24b. When the blocking ball b34 moves up and down, it generates power, and the movable ball e13 jumps inside the second sphere e11 to generate power, causing the expansion plate e2 to vibrate, and impurities attached to the outer wall of the expansion plate e2 shake and slide off, which is conducive to the expansion plate e2 sticking closely to the inner wall of the drainage hole b32.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
