[0002] With the advancement of science and technology, clean energy is now increasingly valued by the Chinese people. Among them, photovoltaic power generation projects are particularly common in daily life. Driven by technological improvements in the photovoltaic field and relevant national policies, photovoltaic projects are now beginning to enter the homes of ordinary people, installing photovoltaic arrays on the roofs of their own homes. The electricity generated by photovoltaic arrays can not only meet the daily electricity needs of the family, but the excess electricity can also become a source of family income, which benefits the country and the people and is very worthy of vigorous promotion.

[0003] A new water-leakage-proof photovoltaic power generation array and installation method provided by the publication number "CN108039854A" include at least two rows of photovoltaic panels, each row of photovoltaic panels has at least one photovoltaic panel; the frame of the photovoltaic panel is fixedly installed on the lower support frame through a connecting piece, and the lower edge of the photovoltaic panel in the upper row covers the upper edge of the photovoltaic panel in the lower row. Correspondingly, it also provides a new water-leakage-proof photovoltaic power generation array installation method, including the following steps: step a, making a lower support frame according to the area of ​​the roof, and fixing the lower support frame to the roof; step b, calculating the number and installation position of the new water-leakage-proof photovoltaic power generation array to be installed according to the size of the lower support frame; step c, fixing the photovoltaic panel to the determined installation position on the lower support frame through a connecting piece, and making the lower edge of the photovoltaic panel in the upper row cover the upper edge of the photovoltaic panel in the next row.

[0004] However, the above device still has the following problems during implementation:

[0005] Nowadays, most home photovoltaic arrays are installed on flat roofs, and the photovoltaic arrays are fixed on the roof by drilling holes with screws. However, the method of drilling holes with screws will damage the waterproof layer of the roof, which will cause the roof to leak on rainy days.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-8 , the present invention provides a technical solution: Example

[0041] A water-leakage-proof photovoltaic power generation array comprises a plurality of bases 1, which are arranged on a flat roof at intervals. At the same time, a fixing rod can be arranged on the side of the base 1 in this embodiment, and a counterweight block is sleeved on the fixing rod, so that the base 1 is more stable during use. The plurality of bases 1 are fixedly connected by a connecting rod 2, and the connecting rod 2 and the base 1 are fixedly connected by a nut. The bases 1 arranged at intervals are fixedly connected by the connecting rod 2. At this time, an integral array is formed between the bases 1, which is more stable. A support rod 3 is fixedly connected above the base 1, and a fixing plate 5 for placing a photovoltaic panel 4 is fixedly connected to the support rod 3. There is a certain angle between the fixing plate 5 and the flat roof. The inclined setting allows the photovoltaic panel 4 to have more sunlight exposure time while ensuring that the photovoltaic panel 4 can have a certain inclination angle. When it rains, rainwater on the photovoltaic panel 4 can slide into the inside of the placement groove 6 under the action of the inclination angle;

[0042] A placement groove 6 is provided inside the fixing plate 5, and the photovoltaic panel 4 is fixedly arranged inside the placement groove 6 by a buckle. The buckle in this embodiment can be a screw-fixed buckle or a clip-type buckle. A connecting channel 7 and a water outlet 8 connected to the placement groove 6 are provided at the bottom of the fixing plate 5. The fixing plate 5 is arranged with a certain inclination angle, and the connecting channel 7 and the water outlet 8 are arranged below the fixing plate 5 along the inclination direction, so as to facilitate the subsequent discharge of accumulated water;

[0043] A water storage chamber 9 is provided inside the base 1, and the water storage chamber 9 is used to collect rainwater inside the placement groove 6. The water storage chamber 9 and the connecting channel 7 are connected by a pipe 701. Under the action of gravity, the rainwater inside the placement groove 6 enters the water storage chamber 9 through the connecting channel 7 and the pipe 701. A floating block 10 is movably provided inside the water storage chamber 9. The floating block 10 is movably provided inside the water storage chamber 9, and is provided near the upper wall of the water storage chamber 9 to identify whether the water inside the water storage chamber 9 is full. The floating block 10 and the inner wall of the water storage chamber 9 are fixedly connected with a first elastic block 11. A water retaining chamber 12 is provided inside the water storage chamber 9, and a water retaining plate 13 that movably blocks the pipe 701 is provided inside the water retaining chamber 12. The water retaining plate 13 and the inner wall of the water retaining chamber 12 are fixedly connected with an elastic rod 131. In the initial state, the water retaining plate 13 is outside the pipe 701. At this time, the pipe The channel 701 is in an unobstructed state. When the water inside the water storage chamber 9 is full, the floating block 10 squeezes the trigger assembly and drives the water baffle 13 to block the channel 701 through the trigger assembly. The water baffle 13 and the inner wall of the water baffle chamber 12 form a closed space. The water baffle 13 is driven by the trigger assembly to block the channel 701. A storage chamber 14 connected to the water storage chamber 9 is opened inside the base 1. A purification block 15 for purifying rainwater is placed inside the storage chamber 14. The purification block 15 is movably blocked by the blocking assembly. In the initial state, the blocking plate 20 is inside the storage chamber 14.

When the blocking plate 20 withdraws from the storage chamber 14, the purification block 15 loses the support of the blocking plate 20. The purification block 15 falls into the water storage chamber 9 under the action of gravity, so that impurities and dust inside the rainwater are settled at the bottom of the water storage chamber 9.

[0044] A water pump 16 is arranged outside the base 1 for transporting the purified water inside the water storage chamber 9 to the surface of the photovoltaic panel 4. The water pump 16 is powered by an external power supply and controlled by an operator. The water pump 16 is connected to the inside of the water storage chamber 9 through one end of a hose, and the other end of the hose extends to the surface of the photovoltaic panel 4. When the photovoltaic panel 4 needs to be cleaned after rain, the water pump 16 and the sewage outlet on the base 1 are opened at this time, and the water pump 16 draws out the purified rainwater inside the water storage chamber 9 and transports it to the upper surface of the photovoltaic panel 4 to clean the photovoltaic panel 4. The cleaned water enters the water storage chamber 9 again through the pipe 701, mixes with the sediment inside the water storage chamber 9, and flushes the sediment out through the sewage outlet. Example

One end of the trigger plate 18 is movably extended into the water storage chamber 9, and the trigger plate 18 and the water baffle 13 are fixedly connected by a pull rope 181. When the water storage chamber 9 is full of rainwater, the float 10 moves up under the action of the buoyancy of the rainwater and squeezes the trigger plate 18. At this time, the trigger plate 18 moves up and pulls the water baffle 13 through the pull rope 181, so that the water baffle 13 blocks the pipe 701. Example

[0046] On the basis of Example 1, the structure of the barrier component in Example 1 is disclosed, and the barrier component includes a barrier chamber 19 opened inside the base 1 and connected to the water retaining chamber 12. An air vent is opened inside the barrier chamber 19 at one end away from the barrier plate 20 to facilitate the subsequent movement of the barrier plate 20. A barrier plate 20 that can be movably extended into the storage chamber 14 is arranged inside the barrier chamber 19. The barrier plate 20 is initially located inside the storage chamber 14, carrying the purification block 15, and the barrier plate 20 and the inner wall of the barrier chamber 19 form a closed space. When the water retaining plate 13 moves to the left to block the pipeline 701, the water retaining plate 13 squeezes the gas inside the water retaining chamber 12 into the barrier chamber 19, driving the barrier plate 20 to exit Storage chamber 14, at this time, the purification block 15 falls into the water storage chamber 9 under the action of gravity, the baffle plate 20 and the inner wall of the baffle chamber 19 are fixedly connected with the second elastic block 21, and an air collecting chamber 22 is opened inside the base 1, and a stirring component for stirring rainwater inside the water storage chamber 9 is arranged inside the air collecting chamber 22, and the air collecting chamber 22 and the baffle chamber 19 are connected through an air channel 23, and the air channel 23 is movably blocked by the air blocking component, and the air collecting chamber 22 and the baffle chamber 19 are located on the right side of the baffle plate 20 and are connected through the air channel 23, and the water baffle chamber 12 is also connected to the right side of the baffle chamber 19, when the gas inside the water baffle chamber 12 enters the baffle chamber 19, the air pressure on the right side of the baffle chamber 19 continuously increases, driving the baffle plate 20 to move to the left.

[0047] Embodiment 4:

[0048] On the basis of the third embodiment, the structure of the stirring assembly in the third embodiment is disclosed. The stirring assembly includes a piston plate 24 movably arranged inside the gas collecting chamber 22. The piston plate 24 and the inner wall of the gas collecting chamber 22 form a closed space. When the gas inside the barrier chamber 19 enters the gas collecting chamber 22, the gas drives the piston plate 24 to move downward. A third elastic block 25 is fixedly connected between the piston plate 24 and the gas collecting chamber 22. A bearing 26, a threaded screw 27 and a stirring block 28 are fixedly connected to the side of the piston plate 24 close to the water storage chamber 9 in sequence. The stirring block 28 is inside the water storage chamber 9, the threaded screw 27 passes through the threaded hole 29 and extends into the water storage chamber 9, the piston plate 24 is rotatably connected to the threaded screw 27 through the bearing 26, one end of the threaded screw 27 movably extends into the water storage chamber 9, and the end of the threaded screw 27 extending into the water storage chamber 9 is fixedly connected with the stirring block 28. When the piston plate 24 moves downward, the threaded screw 27 is driven to move downward. During the process of the threaded screw 27 moving downward through the threaded hole 29, the stirring block 28 is driven to rotate, so as to stir the rainwater inside the water storage chamber 9. The stirring block 15 has a higher purification efficiency inside the water storage chamber 9. An air outlet 30 connected to the air collecting chamber 22 is provided inside the base 1. The connection between the air outlet 30 and the air collecting chamber 22 is located below the piston plate 24 and on the side wall of the air collecting chamber 22. When the piston plate 24 moves downward, the threaded screw 27 is driven downward, and the threaded screw 27 drives the stirring block 28 to rotate. When the piston plate 24 moves to a position exceeding the connection between the air outlet 30 and the air collecting chamber 22, the gas entering the air collecting chamber 22 at this time passes through the air outlet 30. 0 is discharged, at this time the piston plate 24 loses the thrust of the gas, and moves up and resets under the action of the third elastic block 25, and blocks the air outlet 30 again during the resetting process. After being blocked, the gas entering the gas collecting chamber 22 drives the piston plate 24 to move down again. This process is reciprocating until the gas in the barrier chamber 19 is completely discharged. Although the subsequent downward movement of the piston plate 24 may be smaller, the threaded screw 27 can still drive the stirring block 28 to achieve the effect of stirring the rainwater inside the water storage chamber 9. Example

[0049] On the basis of the third embodiment, the structure of the air blocking component in the third embodiment is disclosed. Considering that the structure inside the air collecting chamber 22 is driven by the gas inside the barrier chamber 19, in the present embodiment, the air is firstly collected inside the barrier chamber 19. On the one hand, the movement of the barrier plate 20 is driven by collecting the gas inside the barrier chamber 19. On the other hand, the subsequent structure can be better driven by releasing the high-pressure gas inside the barrier chamber 19. In the present embodiment, the effect of storing air inside the barrier chamber 19 is achieved by controlling the air blocking component. The air blocking component includes an air blocking chamber 31 provided inside the base 1. An air blocking plate 32 that is movable to block the airway 23 is provided inside the air blocking chamber 31. In the initial state, the air blocking plate 32 is in a state of blocking the airway 23. 2 and the inner wall of the air blocking cavity 31 are fixedly connected with a fourth elastic block 33, and a movable rod 34 that is movably pressed against the blocking plate 20 is provided inside the air blocking cavity 31, and one end of the movable rod 34 is movably extended into the blocking cavity 19 and pressed against the blocking plate 20, and a traction rope 35 is fixedly connected between the movable rod 34 and the air blocking plate 32, and a clamping groove 341 is provided on the rod body of the movable rod 34, and a buckle assembly that movably clamps the movable rod 34 is provided inside the air blocking cavity 31. In this embodiment, when gas enters the blocking cavity 19, the gas continuously accumulates inside the blocking cavity 19, driving the blocking plate 20 to move to the left. During the process of the blocking plate 20 moving to the left, the movable rod 34 is squeezed, and at this time, the movable rod 34 pulls the air blocking plate 32 out of the airway 23 through the traction rope 35. Example

[0050] The buckle assembly structure in the fifth embodiment is disclosed. Considering that once the blocking plate 20 squeezes the movable rod 34, the movable rod 34 pulls the air baffle plate 32 out of the airway 23 through the traction rope 35, and the gas inside the blocking cavity 19 begins to be released, and the blocking plate 20 begins to reset. During the reset process, it separates from the movable rod 34. At this time, the air baffle plate 32 blocks the airway 23 again, and the gas inside the blocking cavity 19 cannot be completely discharged. In this embodiment, the buckle assembly is set so that when the blocking plate 20 squeezes the movable rod 34 to move, the movable rod 34 is stuck when the air baffle plate 32 exits the airway 23, so that the inside of the blocking cavity 19 All gases are discharged into the gas collecting chamber 22. The buckle assembly includes an electromagnet 36 fixedly arranged in the gas blocking chamber 31. A magnetic clamping rod 37 that movably extends into the card slot 341 is arranged in the gas blocking chamber 31. The magnetic clamping rod 37 is arranged below the electromagnet 36. The magnetic clamping rod 37 and the electromagnet 36 are magnetically connected, and the magnetic force between the two is an attractive force. The magnetic clamping rod 37 and the inner wall of the gas blocking chamber 31 are fixedly connected with a fifth elastic block 38. In the initial rotation state, the magnetic clamping rod 37 and the movable rod 34 are in an extruded state. At this time, the fifth elastic block 38 is in a compressed state. When the movable rod 34 moves to the left, when the card slot 341 moves to the magnetic clamping rod 3 7, at this time, the magnetic card rod 37 extends into the card slot 341 under the action of the fifth elastic block 38, and the movable rod 34 is clamped. The electromagnet 36 is controlled to open by the pressure-touch switch 39 set in the blocking chamber 19, and the pressure-touch switch 39 and the blocking plate 20 are squeezed. The blocking plate 20 and the pressure-touch switch 39 cooperate to control the on and off of the electromagnet 36. The pressure-touch switch 39 and the electromagnet 36 are connected in series through a wire and an external power supply. When the blocking plate 20 squeezes the pressure-touch switch 39, the electromagnet 36 is energized and has magnetism. When the blocking plate 20 and the pressure-touch switch 39 are separated, the electromagnet 36 is de-energized and loses its magnetism. Magnetism, in the initial state, the blocking plate 20 and the pressure-touch switch 39 are in an extruded state. When gas enters the blocking chamber 19, the blocking plate 20 moves to the left, squeezing the movable rod 34. When the air baffle plate 32 exits the airway 23, the movable rod 34 is stuck with the magnetic clamping rod 37. At this time, the gas inside the blocking chamber 19 enters the gas collecting chamber 22, and the blocking plate 20 is reset to the right. When the gas inside the blocking chamber 19 is completely discharged, the blocking plate 20 squeezes the pressure-touch switch 39, and the electromagnet 36 is energized to drive the magnetic clamping rod 37 to exit the slot 341. At this time, the movable rod 34 is no longer stuck, and the air baffle plate 32 is reset to block the airway 23 again.

[0051] Embodiment seven:

[0052] Taking into account that when the water inside the water storage chamber 9 is full, if it continues to rain, water will accumulate in the placement groove 6, an installation cavity 40 is opened inside the fixed plate 5, and a baffle 41 is arranged inside the installation cavity 40 for movably blocking the water outlet 8. The baffle 41 and the inner wall of the installation cavity 40 are fixedly connected with a sixth elastic block 42. The baffle 41 is fixedly connected to a float 44 movably arranged inside the placement groove 6 through a driving rope 43. In the initial state, the baffle 41 is in a state of blocking the water outlet 8. Once water accumulates in the placement groove 6, the float 44 floats up and pulls the baffle 41 out of the water outlet 8 through the driving rope 43. At this time, the water outlet 8 is opened to discharge the accumulated water inside the placement groove 6.

[0053] Specifically, the purification block 15 is an alum block, and may also be alum powder.

[0054] Specifically, the bottom of the water storage chamber 9 is sloped, and a sewage outlet connected to the water storage chamber 9 is provided inside the base 1, and the sewage outlet is movably blocked by a plug.

[0055] An installation method for the above-mentioned water-leakage-proof photovoltaic power generation array comprises the following steps:

[0056] A. The bases 1 are arranged at intervals on the flat roof according to the set arrangement, and the bases 1 are fixedly connected by connecting rods 2. The photovoltaic panels 4 are fixed inside the placement grooves 6 by buckles, and the photovoltaic panels 4 and the bases 1 can be fixed without drilling holes with screws;

[0057] B. Rainwater, the rainwater in the placement tank 6 enters the water storage chamber 9, and the purification block 15 is used together with the stirring component to purify the rainwater collected in the water storage chamber 9. The purified rainwater is used to clean the photovoltaic panel 4 after rain;

[0058] C. After the rain, turn on the water pump 16 and the sewage outlet to pump out the purified rainwater in the water storage chamber 9 and spray it onto the surface of the photovoltaic panel 4 to clean the photovoltaic panel 4 after the rain.

[0059] Working principle: Place the bases 1 on the flat roof at intervals according to the set arrangement, connect the bases 1 with each other through the connecting rods 2, and fix the photovoltaic panels 4 in the placement grooves 6 through buckles. At this time, the installation of the photovoltaic panels 4 and the photovoltaic array is completed. The entire installation process does not require drilling holes on the flat roof with screws, which fundamentally eliminates the possibility of water leakage.

[0060] When it rains, rainwater falling on the photovoltaic panel 4 slides down to the inside of the placement groove 6, and the water inside the placement groove 6 enters the water storage chamber 9 inside the base 1 through the connecting channel 7 and the pipe 701;

[0061] As the rainwater inside the water storage chamber 9 accumulates continuously, the water level continues to rise, and the floating block 10 rises under the action of the buoyancy of the rainwater, squeezing the trigger plate 18, and driving the trigger plate 18 to move upward. During the upward movement of the trigger plate 18, the water baffle 13 is pulled by the pull rope 181. At this time, the water baffle 13 blocks the pipe 701. At this time, the rainwater inside the placement groove 6 cannot enter the water storage chamber 9. When the rainwater inside the placement groove 6 accumulates, the floating ball 44 moves upward under the action of the buoyancy of the rainwater, and pulls the baffle 41 out of the water outlet 8 through the driving rope 43. At this time, the water outlet 8 is opened to discharge the accumulated water inside the placement groove 6, and the accumulated water inside the placement groove 6 affects the photovoltaic panel 4;

[0062] When the water baffle 13 blocks the pipe 701, the water baffle 13 squeezes the gas in the water baffle chamber 12 into the barrier chamber 19. The gas entering the barrier chamber 19 drives the baffle 20 to move leftward and exit the storage chamber 14. At this time, the purification block 15 falls into the water storage chamber 9 under the action of gravity.

[0063] When the baffle plate 20 moves to the left, the movable rod 34 is squeezed and moved to the left. The movable rod 34 pulls the air baffle plate 32 out of the air passage 23 through the traction rope 35. When the air baffle plate 32 completely withdraws from the air passage 23, the magnetic clamp rod 37 clamps the movable rod 34. At this time, the gas inside the baffle cavity 19 enters the gas collecting cavity 22 through the air passage 23. The baffle plate 20 is reset under the action of the second elastic block 21. When the baffle plate 20 is completely reset, the pressure-touch switch 39 is squeezed. At this time, the electromagnet 36 is energized and has magnetism, which attracts the magnetic clamp rod 37 to withdraw from the card slot 341. At this time, the movable rod 34 and the air baffle plate 32 are reset.

[0064] The gas inside the barrier chamber 19 enters the gas collecting chamber 22, driving the piston plate 24 to drive the threaded screw 27 to move downward. During the process of the threaded screw 27 moving downward through the threaded hole 29, the stirring block 28 is driven to rotate, and the rainwater inside the water storage chamber 9 is stirred, so that the purification efficiency of the purification block 15 is higher. When the piston plate 24 moves downward through the air outlet 30, the gas inside the gas collecting chamber 22 is released. At this time, the piston plate 24 moves upward under the action of the third elastic block 25, and blocks the air outlet 30 again during the upward movement. At this time, the gas inside the barrier chamber 19 is still continuously entering the gas collecting chamber 22. At this time, the piston plate 24 is driven again to drive the threaded screw 27 to move downward. This process is repeated until the gas inside the barrier chamber 19 is completely discharged. During this process, the stirring block 28 continuously stirs the rainwater inside the water storage chamber 9.

[0065] After the rain, the operator turns on the water pump 16 and the drain outlet. The water pump 16 pumps the purified rainwater from the water storage chamber 9 to clean the surface of the photovoltaic panel 4. The cleaned water enters the water storage chamber 9 again to flush the sediment and is discharged through the drain outlet.
