Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation component that is resistant to lodging. Background Art

[0002] Photovoltaic power generation refers to the process of converting solar energy into electrical energy through a photovoltaic power generation system. Photovoltaic power generation modules are the core component of solar power generation systems. These modules are primarily installed outdoors to absorb sunlight, convert it into electrical energy, and then store it in batteries or power a load. PV modules installed outdoors year-round often experience strong winds. Existing PV modules are simply mounted outdoors for stability. Prolonged exposure to the sun and rain can cause the brackets to rust, and welding points in particular are prone to breakage. Cracked welding points can make PV modules vulnerable to being blown away by strong winds. The solar panels mounted on top of the modules can also fall over and be impacted by external forces, causing hidden cracks, which can lead to partial or even complete failure of the cells.

[0003] The patent with publication number CN218162281U discloses an anti-lodging photovoltaic power generation component, including an upper support plate, a slide groove is opened at both ends of the upper side of the upper support plate, and a first screw rod and a second screw rod are respectively installed in the two slide grooves, a lower clamping piece is installed on the threaded sliding installation of the first screw rod, an upper clamping piece is installed on the threaded sliding installation of the second screw rod, and both ends of the photovoltaic power generation panel are clamped between the lower clamping piece and the upper clamping piece, one end of the first screw rod and the second screw rod is connected to a transmission rod through a gear set, a handle is installed on one end of the transmission rod, a lower bracket is installed on the lower side of the upper support plate, and the lower bracket Anti-fall extension rods are inserted on both sides of the lower side, and an anti-fall support plate is installed at one end of the anti-fall extension rod. Since the upper side of the upper support plate is provided with a lower clamping part and an upper clamping part through the sliding of a screw rod, and the two ends of the photovoltaic power generation panel are clamped between the lower clamping part and the upper clamping part, it is convenient to perform clamping and limiting processing on the two ends of the photovoltaic power generation panel, with high positioning stability and convenient and quick disassembly and assembly. However, compared with the existing technology, this device still only reasonably strengthens the supporting strength of the bracket. After the supporting device is eroded by wind and rain and the connection strength is reduced, the risk of being blown down by strong wind will still be greatly increased. Summary of the Invention

[0004] In order to solve the problems mentioned in the above background technology, the present invention provides a photovoltaic power generation component that is resistant to lodging.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A photovoltaic power generation assembly for preventing lodging includes a balancing ball, a main control device, and a supporting device. The balancing ball is placed on a stable seat and includes a spherical shell, an energy storage battery, and an external connecting wire.

The docking joint has a recovery chamber open outward, and the telescopic control head can be controlled by the docking joint to move into the recovery chamber or partially protrude from the recovery chamber. The shaft motor of the docking joint can be controlled to rotate to control the opening direction of the recovery chamber.

[0011] Preferably, a belt-shift gear is installed at the bottom of the telescopic control head, a detection head is installed on the upper surface of the telescopic control head, the motor in the telescopic control head is electrically connected to the docking head, so that it can be controlled and operated by the main control device, annular teeth are arranged in a ring on the lower surface of the embedded ring, and at least one marking piece is provided on the upper surface of the embedded ring. When the belt-shift gear drives the counterweight ball to rotate, the marking piece can be identified when it passes over the detection head.

[0012] Preferably, the main control device includes a controller, a balance ring and a conductive ring. The controller is fixedly installed above the energy storage battery and is powered by the energy storage battery. The balance ring is suspended in the balance space through a circumferentially symmetrical lifting cable. The upper end of the lifting cable is fixed to the surface of the lifting ball. The lifting ball is embedded in the anti-falling ball groove at the lower end of the lifting frame. The lifting ball can rotate freely in the anti-falling ball groove but cannot fall out.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention adopts a counterweight ball and a supporting device to support the photovoltaic panel, and uses the deadweight of the counterweight ball and the elastic force of the supporting device to offset the wind force exerted on the photovoltaic panel, so that the wind force exerted on the photovoltaic panel can be well resisted and dissipated when the photovoltaic panel is hit by gusts, thereby preventing the photovoltaic panel from being blown down by short-term strong gusts.

[0016] 2. The counterweight ball of the present invention is equipped with main control devices above and below that can monitor the tilt state of the counterweight ball. When the photovoltaic panel is blown by long-term gusts of wind, the support device can be controlled to move away from the counterweight ball and no longer support the counterweight ball. At this time, the photovoltaic panel drives the counterweight ball to further deflect under strong winds, and spontaneously deflects downwind under the action of wind. In this state, the wind thrust received by the photovoltaic panel will be further reduced, thereby preventing the photovoltaic panel from being blown down by long-term strong winds.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1

[0024] Reference Figure 1-3 A photovoltaic power generation component that prevents lodging includes a counterweight ball 1, a main control device 2 and a supporting device 3. The counterweight ball 1 is placed on a stable seat 4, the main control device 2 is installed in the counterweight ball 1, and the supporting device 3 is installed on the stable seat 4 and is releasably connected to the counterweight ball 1.

[0025] The stabilizing seat 4 includes a fixed plate 41 and a placement platform 42 installed on the upper surface of the fixed plate 41. The fixed plate 41 is fixedly installed in a designated installation position. The upper surface of the placement platform 42 has a concave surface. The counterweight ball 1 is placed on the upper surface of the placement platform 42, and the inner diameter of the concave surface on the upper surface of the placement platform 42 is larger than the outer diameter of the counterweight ball 1, so that the counterweight ball 1 can be constrained by the inner wall of the concave surface and quickly return to the center after being offset on the upper surface of the placement platform 42.

[0026] The counterweight ball 1 includes a spherical shell 11, an energy storage battery 12 and an external connecting wire 13. The spherical shell 11 is hollow inside and has a mounting plane on the top. The photovoltaic panel 5 and the bracket connected thereto are fixedly installed at the top center of the spherical shell 11. The energy storage battery 12 is fixedly installed at the bottom of the spherical shell 11 as a counterweight device. The photovoltaic panel 5 is electrically connected to the energy storage battery 12. The electric energy generated by the photovoltaic panel 5 will first be input into the energy storage battery 12 for storage. A balancing space 101 for the installation of the main control device 2 is reserved above the energy storage battery 12. The energy storage battery 12 obtains Part of the electric energy can be supplied to the main control device 2 for operation. One end of the external connection wire 13 is installed at the bottom of the energy storage battery 12, and the other end passes through the hole with the lowest point of the concave surface on the upper surface of the placement table 42, so that the electric energy stored in the energy storage battery 12 can be transmitted to the outside for use through the transmission line arranged in the external connection wire 13. When placed normally, the bottom of the spherical shell 11 just covers the hole on the upper surface of the placement table 42 through which the external connection wire 13 is inserted, so that the external connection wire 13 can be stored in the placement table 42 and will not be directly exposed to the sun and rain for a long time to reduce the tensile strength.

[0027] When the counterweight ball 1 and the photovoltaic panel 5 installed on the upper end are blown crooked or even tend to move away from the placement platform 42 by strong wind, the external pull wire 13 will be partially pulled out of the placement platform 42. The end of the external pull wire 13 cannot be separated from the placement platform 42 and the energy storage battery 12, but can pull the counterweight ball 1 that is moving away from the placement platform 42, so that the counterweight ball 1 will not be separated from the placement platform 42. During this process, the photovoltaic panel 5 is affected by the wind and drives the counterweight ball 1 to deflect and move on the upper surface of the fixed plate 41 under the wind. The external pull wire 13 can always pull the counterweight ball 1 and prevent the counterweight ball 1 from being separated from the placement platform 42. The external pull wire 13 is set to a suitable pullable length so that the photovoltaic panel 5 deflected by the wind will not directly contact and hit the fixed plate 41 or the bottom surface on which it is installed, thereby preventing the photovoltaic panel 5 from being collided and damaged.

[0028] Example 2

[0029] Reference Figure 1-3 The difference between this embodiment and embodiment 1 is that an inner ring 102 is provided on the outside of the spherical shell 11, annular teeth 14 are arranged in a ring on the lower surface of the inner ring 102, and at least one marking piece 15 is provided on the upper surface of the inner ring 102.

[0030] The supporting device 3 is provided with at least three, and the supporting device 3 is circumferentially symmetrically arranged outside the counterweight ball 1. The supporting device 3 includes a fixed seat 31, a swinging machine 32, a buffer spring 33, a docking head 34 and a telescopic control head 35. The swinging machine 32 and the docking head 34 are respectively installed at both ends of the buffer spring 33. The swinging machine 32 and the docking head 34 are respectively electrically connected to the main control device 2. The bottom of the swinging machine 32 is installed on the fixed seat 31, and the fixed seat 31 is fixedly installed on the fixed plate 41. The rotating shaft motor of the swinging machine 32 can be controlled to rotate, thereby driving the buffer spring 33 installed at the upper end to swing toward or away from the counterweight ball 1. The docking head 34 has a recovery chamber 301 open outward. The telescopic control head 35 can be controlled by the docking head 34 to move into the recovery chamber 301 or partially protrude from the recovery chamber 301. The rotating shaft motor of the docking head 34 can be controlled to rotate to control the opening direction of the recovery chamber 301.

[0031] The bottom of the telescopic control head 35 is equipped with a belt shift gear 36, and the upper surface of the telescopic control head 35 is equipped with a detection head 37. The motor in the telescopic control head 35 is electrically connected to the docking head 34, so that it can be controlled by the main control device 2. After the counterweight ball 1 is placed on the placement table 42, the swing machine 32 drives the buffer spring 33 to turn to the ball shell 11, so that the docking head 34 is in a state of docking the embedded ring 102 with the recovery cavity 301 and is close to the outer wall of the ball shell 11. Thereafter, the telescopic control head 35 extends from the recovery cavity 301 and enters. Into the embedded ring 102, the telescopic control head 35 can drive the belt shift gear 36 engaged with the annular teeth 14 to rotate, thereby driving the balancing weight ball 1 to rotate axially, and then adjusting the photovoltaic panel 5 installed on the upper part of the balancing weight ball 1 to rotate to a direction with higher power generation efficiency. When the belt shift gear 36 drives the balancing weight ball 1 to rotate, the marking piece 15 can be identified when passing through the detection head 37. After the identification signal is transmitted to the main control device 2, the main control device 2 can identify the direction of the balancing weight ball 1, thereby further controlling the belt shift gear 36 to drive the balancing weight ball 1 to rotate to a suitable power generation direction.

[0032] It can be understood that after the counterweight ball 1 is adjusted to a suitable power generation direction, the support device 3 is kept outside the counterweight ball 1 and remains stable with the shifting gear 36. After the power is cut off from the swing machine 32 and the docking joint 34, their shaft motors can automatically adjust their rotation according to the force. After the photovoltaic panel 5 is pushed by the wind and drives the counterweight ball 1 to deflect, the buffer spring 33 can effectively buffer the tipping thrust and quickly return the counterweight ball 1 to its original position.

[0033] Example 3

[0034] Reference Figure 1-3The difference between this embodiment and embodiments 1 and 2 is that the main control device 2 includes a controller 21, a balance ring 22 and a conductive ring 23. The controller 21 is fixedly installed above the energy storage battery 12 and is powered by the energy storage battery 12. The balance ring 22 is suspended in the balance space 101 through a circumferentially symmetrically arranged lifting cable 24. The upper end of the lifting cable 24 is fixed to the surface of the lifting ball 25. The lifting ball 25 is embedded in the anti-falling ball groove 201 at the lower end of the lifting frame 26. The lifting ball 25 can rotate freely in the anti-falling ball groove 201 but cannot fall out. The upper end of the lifting frame 26 is fixedly installed on the top plate of the balance space 101, thereby suspending the balance ring 22 in the balance space 101.

[0035] Since the hanging ball 25 can rotate freely in the anti-ball groove 201, no matter how the ball shell 11 is offset, the balance ring 22 can always maintain a horizontal state in the balance space 101. The outer edges of the upper and lower surfaces of the balance ring 22 are installed with conductive rings 23, and the conductive rings 23 on the upper and lower surfaces of the balance ring 22 are electrically connected to each other. An upper contact ring 27 is provided above the balance ring 22, and a lower contact ring 28 is installed on the upper surface of the controller 21. The upper contact ring 27 and the lower contact ring 28 are respectively electrically connected to the controller 21, so that the electrical signal sent by the controller 21 can be transmitted to the upper contact ring 27, and the electrical signals received by the upper and lower contact rings 28 can also be sent back to the controller 21.

[0036] When pushed by a small wind force, the photovoltaic panel 5 will drive the counterweight ball 1 to have a small deflection, and can be quickly corrected by the supporting device 3 after the deflection. However, when the photovoltaic panel 5 is continuously blown by strong winds, it will drive the counterweight ball 1 to have a long-term large-scale deflection, so that the conductive rings 23 arranged on the upper and lower surfaces of the balance ring 22, which always maintains a horizontal state in the balance space 101, can directly contact the upper contact ring 27 and the lower contact ring 28 in the spherical shell 11 after the deflection. At this time, the electrical signal transmitted by the controller 21 to the upper contact ring 27 can be transmitted to the lower contact ring 28 through the balance ring 22 and finally received by the controller 21, thereby realizing a signal return closed loop. When the electrical signal transmitted by the controller 21 can realize the signal return closed loop for a period of time, it means that the spherical shell 11 has been deflected to a large extent by the photovoltaic panel 5 affected by the strong wind and has lasted for a period of time.

[0037] In order to ensure that the photovoltaic panel 5 will not continue to move the ball shell 11 under strong winds and pull the support device 3 to cause damage to the components, the controller 21 will control the telescopic control head 35 to move into the recovery chamber 301, and drive the shaft motor of the swing machine 32 to drive the buffer spring 33 to swing away from the counterweight ball 1, so that the support device 3 is away from the counterweight ball 1 and no longer supports the counterweight ball 1. At this time, the photovoltaic panel 5 drives the counterweight ball 1 to further deflect under strong winds, and spontaneously deflects downwind under the action of wind. The wind thrust exerted on the photovoltaic panel 5 in this state will be further reduced, and the force that helps the photovoltaic panel 5 and the counterweight ball 1 to fall over is mainly provided by the gravity of the counterweight ball 1 and the pull-back force provided by the external connecting wire 13 that is usually well protected.

[0038] After the strong wind stops affecting the photovoltaic panel 5, the gravity exerted on the counterweight ball 1 can realign the photovoltaic panel 5, thereby causing the conductive ring 23 of the balance ring 22 to be separated from the upper contact ring 27 and the lower contact ring 28. At this time, the controller 21 can no longer realize the signal return closed loop, thereby driving the shaft motors of each of the swing machines 32 to re-drive the driving buffer spring 33 to swing toward the counterweight ball 1 to re-support the counterweight ball 1.
