Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel mounting brackets, and in particular to a photovoltaic panel mounting bracket system for a photovoltaic power station. Background Art

[0002] Photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon); When using photovoltaic panels, a mounting bracket is required as a carrier. However, the existing mounting bracket is mainly composed of multiple support rods welded together, which only has a simple supporting function. However, the use environment of photovoltaic panels is relatively complex and diverse. For some ships that often sail at sea, in order to reduce the energy consumption rate on board, photovoltaic panels are installed on the ship to generate electricity for the daily life of the crew. However, during the voyage, the ship often shakes. The existing mounting bracket is rigidly connected to the deck. Long-term shaking can easily cause the connection between the mounting bracket and the deck to become loose, and it will also cause the internal components of the photovoltaic panel to become loose, affecting the service life of the photovoltaic panel. In addition, when the ship is shaking, seawater often flows into the deck and contacts the photovoltaic panels. During the day, the seawater on the surface of the photovoltaic panels is evaporated and salt particles are precipitated and remain on the surface of the photovoltaic panels, thus forming salt. The salt not only corrodes the photovoltaic panels, but also affects the photovoltaic panels' absorption of solar energy. In addition, when the ship sails to cold areas, the seawater on the surface of the photovoltaic panels will freeze. The existing de-icing method is mainly to knock with a rubber hammer, which can easily damage the photovoltaic panels. Therefore, a photovoltaic panel mounting bracket system for a photovoltaic power station is proposed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the prior art that the swaying of the ship affects the stability of the connection between the mounting bracket and the deck and that the ice and salt formed on the surface of the photovoltaic panel are difficult to clean, and to propose a photovoltaic panel mounting bracket system for a photovoltaic power station.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A photovoltaic panel mounting bracket system for a photovoltaic power station comprises supporting frames arranged opposite to each other, two of the supporting frames are fixedly connected with static struts arranged opposite to each other, a plurality of mounting boxes are arranged side by side between the static struts, the mounting boxes are rotationally connected to the static struts via a rotating shaft, adjacent mounting boxes are fixedly connected via a connecting block, the side walls of the plurality of mounting boxes are rotationally connected with dynamic struts via a rotating shaft, the surface of the dynamic struts is provided with a notch, and the side walls of the supporting frames are provided with a driving assembly for driving the mounting boxes to rotate; A photovoltaic panel mounting frame is fixedly connected to the inner bottom end of the mounting box, a photovoltaic panel is mounted on the inner side of the photovoltaic panel mounting frame, a mounting frame is mounted on the end face of the mounting box by screws, an elastic light-transmitting film is fixedly connected to the inner wall of the mounting frame, a piston box is fixedly connected to the back side of the mounting box, and a circular slide rail is fixedly connected to the back side of the piston box.

[0005] Preferably, one end of the rotating shaft connecting the installation box and the static strut is fixedly connected to a reduction gear, the driving assembly comprises a driving motor, and the output end of the driving motor is fixedly connected to a driving gear meshing with the reduction gear.

[0010] Preferably, the piston block is made of a metal material with good thermal conductivity, the surface of the damping weight ball is provided with a sponge layer, and the surface of the sponge layer is provided with a smooth film.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution uses a driving assembly, a static strut, a dynamic strut and an installation box. When the photovoltaic panel is not needed at night, the driving assembly is used in conjunction with the static strut and the dynamic strut to turn the installation box over to achieve the folding storage protection function of the photovoltaic panel.

[0012] 2. This solution is provided with an elastic light-transmitting film, a piston box and a piston block.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 7 , a photovoltaic panel mounting bracket system for a photovoltaic power station comprises relatively arranged support frames 1, relatively arranged static struts 2 are fixedly connected between the two support frames 1, a plurality of mounting boxes 3 are arranged side by side between the static struts 2, the mounting boxes 3 are rotatably connected to the static struts 2 via a rotating shaft, adjacent mounting boxes 3 are fixedly connected via a connecting block, the side walls of the plurality of mounting boxes 3 are rotatably connected to a dynamic strut 6 via a rotating shaft, the length of the rotating shaft between the mounting box 3 and the dynamic strut 6 is less than the length of the rotating shaft between the mounting box 3 and the static strut 2; a notch 601 is provided on the surface of the dynamic strut 6, the notch 601 can make the dynamic strut 6 and the static strut 2 overlap with each other (the overlap is the engagement of the notch with the rotating shaft between the mounting box 3 and the static strut 2), thereby ensuring that the mounting box 3 can realize the flipping function; The side wall of the support frame 1 is provided with a driving assembly for driving the installation box 3 to rotate; further, one end of the rotating shaft connecting the installation box 3 and the static support rod 2 is fixedly connected to a reduction gear 7, and the driving assembly includes a driving motor 9, and the output end of the driving motor 9 is fixedly connected to a driving gear 8 meshing with the reduction gear 7.

[0020] It should be noted that: the driving motor 9 (the driving motor 9 is a self-locking motor, and an anti-corrosion shell is provided on the outer side of the driving motor 9) is used to drive the driving gear 8 at its output end to rotate, so that the driving gear 8 drives the reduction gear 7 meshing with it to rotate, and the reduction gear 7 drives the installation box 3 to rotate through the rotating shaft, thereby providing driving force for the flipping of the installation box 3.

[0021] It is worth noting that the radius of the driving gear 8 is smaller than the radius of the reduction gear 7, so as to ensure that the installation box 3 can be slowly rotated and turned over.

[0022] It should be noted that the dynamic struts 6 can drive the installation boxes 3 at various locations to rotate together to realize the flipping function. After the installation boxes 3 are flipped over, the installation boxes 3 at various locations are on the same horizontal plane and are arranged facing the deck, which can prevent seawater from accumulating or ice on the elastic transparent membrane 5 at night.

[0023] A photovoltaic panel mounting frame 14 is fixedly connected to the inner bottom end of the mounting box 3, a photovoltaic panel is mounted on the inner side of the photovoltaic panel mounting frame 14, a mounting frame 4 is mounted on the end face of the mounting box 3 by means of screws, an elastic light-transmitting film 5 is fixedly connected to the inner wall of the mounting frame 4, a piston box 13 is fixedly connected to the back side of the mounting box 3, further, the piston block 16 is formed by relatively arranged combination blocks 1601 being spliced ​​together by screws, a semi-cylindrical groove is provided on the splicing surface of the combination block 1601, an electric heating rod 18 is installed inside the semi-cylindrical groove, and the piston block 16 is made of a metal material with good thermal conductivity.

[0024] It should be noted that the installation box 3 can protect the photovoltaic panel and prevent seawater from directly contacting the photovoltaic panel, thereby preventing the photovoltaic panel from being corroded.

[0025] It should be noted that: during the swaying of the ship, seawater often flows into the deck and then splashes on the surface of the elastic light-transmitting film 5. During the day, under the action of sunlight, the seawater is evaporated, and the salt in the seawater is analyzed to form salt on the elastic light-transmitting film 5, or when the ship sails to cold waters, the seawater on the surface of the elastic light-transmitting film 5 will freeze. At night, after the installation box 3 is turned over, under the action of the piston block 16's own gravity, the piston block 16 will move down and squeeze the air inside the piston box 13, thereby squeezing the air inside the piston box 13 into the installation box 3 through the air hole 301, so that the elastic light-transmitting film 5 expands. After the elastic light-transmitting film 5 expands, its surface area will increase significantly, thereby cracking the salt or ice on its surface and reducing the adhesion of the salt or ice. At this time, because the elastic light-transmitting film 5 faces the deck, under the action of the salt or ice's own gravity and the swaying of the ship, it can help the salt or ice fall off. It is worth noting that: during the turning over of the installation box 3, the electric heating rod 18 starts to heat the piston block 16, and the piston block 16 can heat the air inside the installation box 3, so that the air injected into the installation box 3 is hot gas, and the hot gas can melt the salt or ice on the elastic transparent film 5 to a certain extent, further reduce the adhesion of the salt or ice, and accelerate the shedding of the salt or ice.

[0026] It should be noted that the elastic light-transmitting film 5 is usually made of a polymer material with high elasticity, which can provide good transparency and elasticity, such as LLDPE elastic film and TPU film.

[0027] A circular slide rail 10 is fixedly connected to the back of the piston box 13. Furthermore, a guide hole is opened at the center of the back of the piston box 13. A piston block 16 is slidably arranged inside the piston box 13. A guide column 17 slidably connected to the guide hole is fixedly connected at the center of the back of the piston block 16. Furthermore, a hanging rope 12 is fixedly connected to one end of the guide column 17, and a damping weight ball 11 is fixedly connected to one end of the hanging rope 12. Furthermore, a sponge layer is arranged on the surface of the damping weight ball 11, and a smooth film is arranged on the surface of the sponge layer.

[0028] It should be noted that: when the photovoltaic panel is in normal use, the damping weight ball 11 is in a suspended state under the action of the hanging rope 12, and the sponge layer on the surface of the damping weight ball 11 can play a buffering role when the damping weight ball 11 collides with the installation box 3, thereby reducing the impact of the collision; The provision of the smooth film can significantly reduce the friction between the damping weight ball 11 and the circular slide rail 10 , thereby preventing the damping weight ball 11 from shaking synchronously with the circular slide rail 10 due to excessive friction.

[0029] When the photovoltaic panel is in normal use, the damping weight ball 11 will perform a simple pendulum during the swaying of the ship. Through the principles of tuning and resonance, the damping weight ball 11 will buffer the mounting bracket and the ship, reducing the swaying amplitude of the mounting bracket and the ship (the design of the damping weight ball 11 is similar to a simple pendulum. By reasonably designing the pendulum length and mass, the frequency of its swing is close to the swaying frequency of the ship and the mounting bracket, thereby absorbing a large amount of energy during resonance and reducing the vibration of the ship and the mounting bracket. That is, when the ship and the mounting bracket begin to sway due to wind or waves, the damping weight ball 11 will move in the opposite direction to the movement of the ship and the mounting bracket, generating a reaction force and reducing the overall movement of the ship and the mounting bracket).

[0030] When the mounting box 3 is turned over, the piston block 16 moves downward, which drives the guide column 17 to move downward, and then pulls the damping weight ball 11 to move through the hanging rope 12, and pulls the damping weight ball 11 to the inside of the circular slide rail 10 (the mass of the piston block 16 is greater than the mass of the damping weight ball 11). When the mounting box 3 after turning over shakes with the mounting bracket, when the circular slide rail 10 shakes to the right with the mounting box 3, due to the inertia of the damping weight ball 11 itself, the damping weight ball 11 will not move synchronously with the circular slide rail 10. The circular slide rail 10 does not swing to the right, but the damping weight ball 11 starts to swing to the right after the circular slide rail 10 finishes swinging. During the movement of the damping weight ball 11 to the right, the circular slide rail 10 has already started to swing to the left along with the mounting box 3. Therefore, the damping weight ball 11 always rolls on the inner side of the circular slide rail 10 toward a position opposite to the swinging direction, giving a reverse force to the circular slide rail 10 and the mounting box 3, that is, giving a reverse force to the mounting bracket and the vessel, thereby playing a buffering role.

[0031] Furthermore, the four corners of the photovoltaic panel installation frame 14 are connected with steering limit plates 15 via damping shafts, and a plurality of air holes 301 are opened on the back of the installation box 3 .

[0032] It should be noted that the turning limit piece 15 can limit the four corners of the photovoltaic panel, so as to realize the function of installing the photovoltaic panel inside the photovoltaic panel installation frame 14 .

[0033] When the present invention is used, the installation box 3 is in a tilted state, so that the photovoltaic panel is in a tilted state facing the sun, ensuring the normal use of the photovoltaic panel. The setting of the installation box 3 can protect the photovoltaic panel, prevent seawater from directly contacting the photovoltaic panel, and thus prevent the photovoltaic panel from being corroded.

[0034] When the swaying of the ship drives the mounting bracket to sway, the damping weight ball 11 will perform a simple pendulum, and through the principle of tuning and resonance, the damping weight ball 11 will play a buffering role on the mounting bracket and the ship, reducing the swaying amplitude of the mounting bracket and the ship (the design of the damping weight ball 11 is similar to a simple pendulum, and through the reasonable design of the pendulum length and mass, the frequency of its swing is close to the swaying frequency of the ship and the mounting bracket, so that a large amount of energy is absorbed during resonance, reducing the vibration of the ship and the mounting bracket, that is, when the ship and the mounting bracket begin to sway due to wind or waves, the damping weight ball 11 will move in the opposite direction of the movement of the ship and the mounting bracket, generating a reaction force, reducing the overall movement of the ship and the mounting bracket), thereby reducing the swaying amplitude of the photovoltaic panel, reducing the impact of the swaying on the internal parts of the photovoltaic panel, and improving the stability of the connection between the support frame 1 and the deck; When the photovoltaic panel is not needed at night, the driving motor 9 is turned on, and the driving motor 9 drives the driving gear 8 at its output end to rotate, and the driving gear 8 drives the reduction gear 7 meshing therewith to rotate slowly, and the reduction gear 7 drives the installation box 3 connected thereto to rotate through the rotating shaft, and under the action of the dynamic strut 6, drives the installation boxes 3 at various locations to rotate synchronously, so as to realize the turning over function of the installation box 3. During the turning over process of the installation box 3, the electric heating rod 18 inside the piston block 16 starts to heat up, and then heats the piston block 16. The heated piston block 16 can heat the air inside the piston box 13. When the installation box 3 is turned over, the installation boxes 3 at various locations are on the same horizontal plane, and the elastic light-transmitting film 5 is arranged facing the deck, so as to realize the storage and protection function of the photovoltaic panel; After the installation box 3 is turned over, the piston block 16 moves downward under the action of its own gravity, and squeezes the hot air inside the piston box 13 into the installation box 3 through the air hole 301, thereby expanding the elastic transparent film 5. After the elastic transparent film 5 expands, its surface area will increase significantly, thereby cracking the salt or ice surface on its surface, and reducing the adhesion of the salt or ice surface. Since the elastic transparent film 5 faces the deck at this time, the salt or ice surface can be helped to fall off under the action of its own gravity and the shaking of the ship. At the same time, the hot gas can melt the salt or ice surface on the elastic transparent film 5 to a certain extent, further reducing the adhesion of the salt or ice surface, accelerating the reduction of the falling of the salt or ice surface, and realizing the automatic cleaning function of the salt or ice surface; The downward movement of the piston block 16 will drive the guide column 17 to move downward, and the guide column 17 will pull the damping weight ball 11 to move through the hanging rope 12 (the mass of the piston block 16 is greater than the mass of the damping weight ball 11), and then pull the damping weight ball 11 to the inside of the circular slide rail 10. When the ship shakes at night, the turned-over installation box 3 shakes with the installation bracket. When the circular slide rail 10 shakes to the right with the installation box 3, the damping weight ball 11 will not shake to the right synchronously with the circular slide rail 10 due to its own inertia. Instead, the damping weight ball 11 starts to swing to the right after the circular slide rail 10 stops swinging. During the movement of the damping weight ball 11 to the right, the circular slide rail 10 has already started to swing to the left along with the mounting box 3. Therefore, the damping weight ball 11 always rolls on the inner side of the circular slide rail 10 toward a position opposite to the swinging direction, giving a reverse force to the circular slide rail 10 and the mounting box 3, that is, giving a reverse force to the mounting bracket and the vessel, thereby buffering the mounting bracket and the vessel, and further reducing the impact of the swing on the photovoltaic panel.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
