Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power stations, in particular to a detachable distributed photovoltaic structure. BACKGROUND

[0002] With the development of society, the demand for energy is increasing, and distributed photovoltaic power stations, as an important carrier of green and clean energy, play a key role in energy saving and emission reduction, and energy pressure relief. Photovoltaic panels, as the core component of distributed photovoltaic power stations, convert solar energy into electricity through the photoelectric effect, providing sustainable power support for families, businesses and public facilities, and playing an important role in promoting energy structure transformation.

[0003] However, the existing photovoltaic panels have many inconveniences during installation. On the one hand, the installation structure of traditional photovoltaic panels is complex, and usually requires the use of various tools for tedious bolt fixing, with many installation steps and a large amount of labor and time cost. On the other hand, the installation requires high precision of the installation position, and once an error occurs, it will not only affect the power generation efficiency of the photovoltaic panel, but also may cause uneven stress of the connecting components, increasing the safety hazard. In addition, when the photovoltaic panel needs to be replaced due to damage, the installation structure is not detachable or difficult to detach, making the maintenance work difficult and time-consuming, and seriously affecting the normal operation and power generation benefit of the photovoltaic power station.

[0004] In addition, the existing photovoltaic panels are basically installed outdoors or on rooftops, and are exposed to the sun for a long time, which will accumulate a lot of dust and debris, thereby affecting the power generation efficiency of the photovoltaic assembly. In order to ensure the power generation efficiency, the photovoltaic panel needs to be cleaned, and the current manual cleaning has the disadvantages of high cost, low efficiency and high safety risk. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a detachable distributed photovoltaic structure, which can solve the problems of complex installation structure, time-consuming and labor-consuming installation, high installation precision requirement and difficult maintenance and replacement of the existing photovoltaic panel, thereby affecting the power generation efficiency and power station operation benefit.

[0006] To achieve the above purpose, the present application is realized by the following technical scheme: a detachable distributed photovoltaic structure, comprising a base, an adjusting frame is installed on the top of the base, a supporting frame is installed on the top of the adjusting frame, an installation plate is fixedly installed on the top of the supporting frame, a photovoltaic panel body is bolted on the top of the installation plate, and the installation plate is detachably connected with the supporting frame through a connecting assembly. The connecting assembly includes multiple connecting blocks distributed at the bottom of the mounting plate and multiple sets of locking block mechanisms correspondingly arranged on the support frame. Each connecting block has a locking hole for locking with the corresponding locking block mechanism. A sliding groove is provided on the support frame at the position corresponding to each set of locking block mechanisms. The multiple sets of locking block mechanisms are slidably installed in the corresponding sliding grooves and are connected by pull ropes and multiple rollers.

The spring is located on the side of the moving block away from the locking block. One end of the spring is connected to the moving block, and the other end is connected to the sliding groove.

[0007] A further technical solution of the present invention: The adjusting frame includes two uprights disposed on one side of the base and two adjusting rods symmetrically disposed on the other side of the base. The top of the uprights is movably connected to the bottom of the support frame, and the two uprights are connected by a first crossbar. The adjusting rods include a first connecting rod, a second connecting rod, and a third connecting rod that are rotatably connected to each other. The first connecting rod is movably mounted on the base, and the top of the third connecting rod is movably connected to the bottom of the support frame. The second connecting rods of the two adjusting rods are connected by a second crossbar. An adjusting mechanism is provided between the first crossbar and the second crossbar, and the height of the two adjusting rods is controlled by the adjusting mechanism.

[0008] A further technical solution of the present invention: The self-cleaning component includes a mounting frame, a drive rod, a drive motor, a cleaning brush, and two sets of transmission components. The mounting frame includes a horizontal frame disposed on the upper edge of the photovoltaic panel body and vertical frames on the left and right side edges. The drive rod is rotatably mounted in the horizontal frame of the mounting frame, and the drive motor is disposed at one end of the drive rod and controls the rotation of the drive rod. The two sets of transmission components are symmetrically disposed in the two vertical frames of the mounting frame. Each set of transmission components includes a lead screw, a first bevel gear, and a second bevel gear. The lead screw is rotatably mounted in the vertical frame. The first bevel gear is fixed at one end of the lead screw near the drive rod, and the second bevel gear is fixed at the end of the drive rod and meshes with the first bevel gear. The cleaning brush is horizontally disposed on the surface of the photovoltaic panel body, and its two ends are threadedly connected to the two lead screws respectively.

[0009] The preferred technical solution of the present invention is as follows: the support frame is I-shaped, and the connecting block, locking block mechanism and rollers are provided in four sets. The four sets of locking block mechanisms are distributed at the four corners of the I-shaped support frame, and the four connecting blocks are respectively arranged at the corresponding positions on the mounting plate. The locking hole on each connecting block matches the locking block. The four rollers are distributed at the connection parts of the horizontal and vertical rods of the I-shaped support frame, and the turning point of the pull rope is wrapped around the outer wall of the roller.

[0010] A preferred technical solution of the present invention is as follows: the adjusting mechanism includes a rotating shaft, one end of which is rotatably connected to the first crossbar, and the other end is provided with an external thread, which is threadedly connected to the second crossbar through the external thread.

[0011] A preferred technical solution of the present invention: The self-cleaning component further includes a water storage tank, a water pump, a hose, a drain pipe, and a nozzle. The water storage tank is placed on the outside of the base. The water pump is fixedly installed inside the water storage tank. A hose is fixedly installed on the top of the water pump. A drain pipe is fixedly installed inside the horizontal block of the mounting frame. The hose is connected to the drain pipe. Multiple nozzles are fixedly connected to the outer wall of the drain pipe. The nozzles penetrate the mounting frame.

[0012] A preferred technical solution of the present invention is as follows: a support ring is fixedly connected to the outer wall of the rotatable connection between the rotating shaft and the first crossbar, and the support ring is fixed inside the first crossbar.

[0013] A preferred technical solution of the present invention is as follows: a throttle is fixedly connected to the end of the rotating shaft near the first crossbar, and a stop block is fixedly connected to the end of the rotating shaft near the second crossbar.

[0014] This invention provides a detachable distributed photovoltaic structure. It has the following advantages: (1) By setting up a connecting component, when installing the photovoltaic panel body, pulling the handle causes the four moving blocks to slide in the slide groove 602 via the pull rope. The moving blocks drive the locking block to move, compressing the spring and causing the locking block to move. At this time, the connecting block at the bottom of the mounting plate is locked in the slot at the top of the support frame. Releasing the handle causes the spring to recover its deformation and generate elastic force, pushing the moving block and the locking block to reset, so that the locking block is locked back into the locking slot of the connecting block, thus realizing a quick locking connection between the mounting plate and the support frame. When disassembling, pulling the handle again and repeating the above operation can separate the panels. This connection method does not require the use of complex tools. The installation and disassembly of the photovoltaic panel body can be completed through a simple pulling and closing operation, which greatly improves the efficiency of installation and maintenance, reduces manpower and time costs, and also reduces the risk of damage to the photovoltaic panel due to improper installation and disassembly. (2) By setting up an adjustment frame, when it is necessary to adjust the angle of the photovoltaic panel body, the throttle is turned, and the throttle drives the rotating shaft to rotate. Since the external thread on the outer wall of the rotating shaft is engaged with the screw hole inside the second crossbar, when the rotating shaft rotates, the second crossbar will move closer to or further away from the first crossbar along the axis of the rotating shaft. During the movement of the second crossbar, the upright plays a stabilizing support role, while the first connecting rod, the second connecting rod and the third connecting rod are movably connected, which can flexibly change the angle and length, thereby driving the support frame and the photovoltaic panel body installed on it to change the tilt angle. By precisely adjusting the number of rotations of the rotating shaft, the photovoltaic panel body can be adjusted to the optimal light-receiving angle, effectively improving the photovoltaic panel's solar energy reception and conversion efficiency, thereby improving the power generation efficiency of the entire photovoltaic power station, and at the same time, it can adapt to different installation environments and lighting conditions.

[0015] (3) The present invention is equipped with a self-cleaning component. When dust or impurities accumulate on the top of the photovoltaic panel, the drive motor is turned on to drive the drive rod to rotate. Then, through the meshing of the first bevel gear and the second bevel gear, the two lead screws are driven to rotate. When the lead screws rotate, the cleaning brush slides longitudinally on the top of the photovoltaic panel. At the same time, the water pump inside the water tank is started to pump the cleaning liquid inside the water tank into the hose, and then spray it out from the nozzle through the drain pipe. Combined with the movement of the cleaning brush, the top of the photovoltaic panel is cleaned, realizing the ability to automatically clean the dust or impurities accumulated on the top of the photovoltaic panel without manual cleaning, reducing labor costs, and also adapting to more areas with a large amount of dust.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 provides a detachable distributed photovoltaic structure, such as Figures 1 to 15As shown, the system includes a base 1, which serves as the fundamental support component of the entire photovoltaic power station structure, providing a stable installation platform for other components such as the adjustment frame 2. The adjustment frame 2 is installed on the top of the base 1, used to adjust the tilt angle of the photovoltaic panel body 5, enabling it to better receive solar energy and improve power generation efficiency. A support frame 3 is installed on the top of the adjustment frame 2, acting as a connecting element and transmitting the force for angle adjustment. An installation plate 4 is fixedly installed on the top of the support frame 3, providing an installation plane and fixed position for the photovoltaic panel body 5. The photovoltaic panel body 5 is bolted to the top of the installation plate 4. The photovoltaic panel body 5 is the core component for converting solar energy into electrical energy. A connecting component 6 is installed between the support frame 3 and the installation plate 4, enabling quick connection and disassembly between the installation plate 4 and the support frame 3, facilitating the installation, maintenance, and replacement of the photovoltaic panel body 5. In Example 1, as Figures 6 to 8As shown, the connecting assembly 6 includes multiple connecting blocks 601 distributed at the bottom of the mounting plate 4 and multiple sets of locking block mechanisms correspondingly arranged on the support frame 3. A groove 602 is provided on the support frame 3 at the position corresponding to each set of locking block mechanisms. The multiple sets of locking block mechanisms are slidably installed in the corresponding grooves 602, and are connected by a pull rope 606 and multiple rollers 608. The multiple rollers 608 are rotatably installed on the support frame 3 at positions corresponding to the reversal of the pull rope 606. Each set of locking block mechanisms is connected to a pull rope 606, and the multiple pull ropes 606 extend from the same position on the support frame 3 after winding around the multiple rollers 608. A handle 607 is provided at the control end of the pull rope 606, which can simultaneously control multiple pull ropes 606. Each locking block mechanism includes a moving block 603, a locking block 604, and a spring 605. The connecting block 601 is used to connect with the support frame 3 and has a locking groove inside to provide a locking position for the locking block 604. The moving block 603 is slidably installed in the slide groove 602, and the locking block 604 is fixedly installed on the outer end of the moving block 603. The spring 605 is located on the side of the moving block 603 away from the locking block 604, and the other end of the spring 605 is connected to the slide groove 602. The slide groove 602 provides installation space and movement guidance for components such as the moving block 603 and the locking block 604. The moving block 603 is slidably installed inside the slide groove 602 and can slide in the slide groove 602, driving the locking block 604 to move, thereby achieving locking and unlocking with the connecting block 601. In the locked state, the locking block 604 is located inside the locking groove. It locks the mounting plate 4 and the support frame 3 by cooperating with the locking groove. A spring 605 is installed between the end of the slide groove 602 away from the locking block 604 and the inner cavity of the slide groove 602. The spring 605 undergoes elastic deformation when the moving block 603 moves, storing and releasing elastic potential energy to provide power for locking and unlocking the locking block 604. In the attached diagram of the embodiment, the support frame 3 has an I-shaped structure. For easy installation and locking, connecting blocks 601 are fixed to the four corners of the bottom of the mounting plate 4, and four sliding grooves 602 and four sets of locking mechanisms are correspondingly provided. A pull rope 606 is fixedly connected to the end of each of the four sliding grooves 602 away from the locking block 604. The pull rope 606 is used to transmit pulling force, transferring the force of pulling the handle 607 to the moving block 603. The end of the pull rope 606 away from the moving block 603 extends to the outer wall of the support frame 3. A handle 607 is fixedly installed at the end of each pull rope 606 extending to the outer wall of the support frame 3. The operator controls the operation of the connecting component 6 by pulling the handle 607. In this embodiment, four rollers 608 are movably installed inside the support frame 3. The turning point of the pull rope 606 is wrapped around the outer wall of the roller 608. The roller 608 changes the direction of the pulling force of the pull rope 606 and reduces friction, making it easier to pull the handle 607 and improving the convenience of operation. Example 1 provides a detachable distributed photovoltaic structure, such as Figures 1 to 5 , Figure 9As shown, the adjustment frame 2 includes two uprights 201 disposed on one side of the base 1 and two adjustment rods symmetrically disposed on the other side of the base 1. The top of the uprights 201 is movably connected to the bottom of the support frame 3. The uprights 201 provide stable support for the adjustment frame 2 and the support frame 3, while allowing the support frame 3 to rotate within a certain range. The two uprights 201 are connected by a first crossbar 202. The first crossbar 202 is used to install components such as the rotating shaft 207, and also plays a certain connecting and supporting role during the adjustment process. The two adjustment rods are connected by a second crossbar 206. A rotating shaft 207 is provided between the first crossbar 202 and the second crossbar 206. One end of the rotating shaft 207 is rotatably connected to the first crossbar 202, and the other end is provided with an external thread 209, which is threadedly connected to the second crossbar 206 through the external thread 209. The adjusting rod includes a first connecting rod 203, a second connecting rod 204, and a third connecting rod 205 that are rotatably connected to each other. The first connecting rod 203 is movably mounted on the base 1. The second connecting rod 204 is movably mounted on the top of the first connecting rod 203. The third connecting rod 205 is movably mounted on the top of the second connecting rod 204. The top of the third connecting rod 205 is movably connected to the bottom of the support frame 3. The movable connection of the first connecting rod 203, the second connecting rod 204, and the third connecting rod 205 allows the angle and length to be changed when the second crossbar 206 moves, thereby achieving adjustment of the support. The angle of the frame 3 and the photovoltaic panel body 5 is adjusted. The second crossbar 206 is fixedly connected between the two second connecting rods 204. The second crossbar 206 cooperates with the rotating shaft 207 and moves through the threaded transmission, thereby driving the second connecting rod 204 and other components to move. The rotating shaft 207 is rotatably installed inside the first crossbar 202. The outer wall of the rotating shaft 207 is provided with an external thread 209. The second crossbar 206 is provided with a screw hole corresponding to the external thread 209. The movement of the second crossbar 206 is realized through the rotation of the rotating shaft 207 and the cooperation between the external thread 209 and the screw hole. In Example 1, as Figure 10 As shown, a support ring 208 is fixedly connected to the outer wall of the rotatable connection between the rotating shaft 207 and the first crossbar 202. The support ring 208 is rotatably installed inside the first crossbar 202, providing support for the rotating shaft 207 to ensure its stability during rotation and reduce swaying. A handle 210 is fixedly connected to the right side of the rotating shaft 207 (i.e., the end near the first crossbar 202). The handle 210 is located on the right side of the first crossbar 202, and the operator drives the rotating shaft 207 to rotate by turning the handle 210, facilitating operation. Figure 11 As shown, a stop 211 is fixedly connected to the left side of the rotating shaft 207 (i.e., the end near the second crossbar 206). The stop 211 is located on the left side of the second crossbar 206 and is used to limit the range of movement of the second crossbar 206 to prevent the second crossbar 206 from moving excessively, which could cause structural damage or loss of adjustment function.

[0020] The working process of Example 1 is as follows: When the photovoltaic panel body 5 needs to be installed, the operator pulls the handle 607. The handle 607 transmits the pulling force through the pull rope 606. Since the pull rope 606 is wrapped around the roller 608, the roller 608 changes the direction of the pulling force, causing the four moving blocks 603 to slide simultaneously away from the connecting block 601 in the sliding groove 602. The moving blocks 603 drive the locking block 604 to move together, compressing the spring 605 and causing the locking block 604 to move. At this time, the connecting block 601 at the bottom of the mounting plate 4 is accurately locked in the slot at the top of the support frame 3. Then, the handle 607 is released. The spring 605 has a tendency to return to its original shape due to elastic deformation. The elastic force generated pushes the moving blocks 603 and the locking block 604 to reset, so that the locking block 604 is locked in the locking groove of the connecting block 601, thereby realizing the firm connection between the mounting plate 4 and the support frame 3 and completing the installation of the photovoltaic panel body 5. This installation method is simple and quick to operate, requires no complicated tools or professional skills, and greatly shortens the installation time.

[0021] When the photovoltaic panel body 5 malfunctions and needs to be disassembled for repair, pull the handle 607 again and repeat the above operation of pulling the handle 607 to make the locking block 604 exit the locking groove. After the locking block 604 is completely removed from the locking groove of the connecting block 601, the mounting plate 4 and the photovoltaic panel body 5 can be easily removed from the support frame 3, which facilitates the inspection, repair or replacement of the photovoltaic panel body 5. If the angle of the photovoltaic panel body 5 needs to be adjusted to obtain the best solar energy reception effect, the operator turns the handle 210. The handle 210 drives the rotating shaft 207 to rotate. Since the external thread 209 on the outer wall of the rotating shaft 207 cooperates with the screw hole inside the second crossbar 206, when the rotating shaft 207 rotates, the second crossbar 206 will move closer to or away from the first crossbar 202 along the axis of the rotating shaft 207. During the movement of the second crossbar 206, the upright 201 plays a stabilizing support role, ensuring the stability of the entire adjustment frame 2 structure. The first connecting rod 203 and the second connecting rod... The second crossbar 204 and the third connecting rod 205 are movably connected. They can flexibly change their angle and length according to the movement of the second crossbar 206, thereby driving the support frame 3 and the photovoltaic panel body 5 installed on it to change their tilt angle. By precisely controlling the number of rotations of the throttle 210, the photovoltaic panel body 5 can be adjusted to a suitable angle to maximize the absorption of solar energy and improve power generation efficiency. At the same time, the support ring 208 on the rotating shaft 207 ensures that the rotating shaft 207 rotates smoothly, and the stop block 211 limits the movement range of the second crossbar 206 to ensure that the angle adjustment process is safe and reliable.

[0022] Example 2 provides a detachable distributed photovoltaic structure, whose main structure is the same as that of Example 1. The difference lies in that the detachable distributed photovoltaic structure in Example 2, such as... Figures 1 to 5The outer wall of the photovoltaic panel body 5 is equipped with a self-cleaning component 7 to achieve automatic cleaning and prevent outdoor dust from accumulating on the surface of the photovoltaic panel body 5 and affecting its power generation efficiency. Figures 12 to 15 As shown, the self-cleaning assembly 7 includes a mounting frame 701, a drive rod 702, a drive motor 706, a cleaning brush 707, and two sets of transmission assemblies. The mounting frame 701 includes a horizontal frame located on the upper edge of the photovoltaic panel body 5 and vertical frames on the left and right sides, providing mounting support for important components in the self-cleaning assembly 7. The drive rod 702 is rotatably mounted in the horizontal frame of the mounting frame 701 and drives two lead screws 703 to rotate. The drive motor 706 is located at one end of the drive rod 702, providing rotational power for the drive rod 702. The drive motor 706 is fixedly connected to the right side of the drive rod 702 and controls the rotation of the drive rod 702. The two sets of transmission assemblies are symmetrically arranged in the two vertical frames of the mounting frame 701. Each set of transmission assemblies includes a lead screw 703, a first bevel gear 704, and a second bevel gear 705. The lead screw 703 is rotatably mounted inside the vertical frame. The first bevel gear 704 is fixed at one end of the lead screw 703 near the drive rod 702, and the second bevel gear 705 is fixed at the end of the drive rod 702 and meshes with the first bevel gear 704. The second bevel gear 705 is located to the left of the first bevel gear 704. The rotational power of the drive rod 702 is transferred to the two lead screws 703 through the meshing of the first bevel gear 704 and the second bevel gear 705. The fact that the second bevel gear 705 is located to the left of the first bevel gear 704 enables the two lead screws 703 to rotate in the same direction when the drive rod 702 rotates. The cleaning brush 707 is horizontally arranged on the surface of the photovoltaic panel body 5. Its two ends are threaded to the two lead screws 703 respectively. The rotation of the two lead screws 703 in the same direction drives the cleaning brush 707 to slide longitudinally on the top of the photovoltaic panel body 5, thereby cleaning the dust on the top of the photovoltaic panel body 5.

[0023] In the embodiments, such as Figure 14As shown, the self-cleaning component 7 also includes a water storage tank 708, a water pump 709, a hose 710, a drain pipe 711, and a nozzle 712. The water storage tank 708 is placed on the outside of the base 1. The water pump 709 is fixedly installed inside the water storage tank 708 to pump the cleaning liquid inside the water storage tank 708 to the hose 710. The hose 710 is fixedly installed on the top of the water pump 709. The hose 710 can deliver the cleaning liquid. At the same time, the material of the hose 710 allows it to bend when the adjustment frame 2 moves the photovoltaic panel body 5 to adjust the angle without affecting the delivery of the cleaning liquid. The drain pipe 711 is fixedly installed inside the horizontal block of the mounting frame 701. The hose 710 is connected to the drain pipe 711. Multiple nozzles 712 are fixedly connected to the outer wall of the drain pipe 711. The nozzles 712 penetrate the mounting frame 701. The multiple nozzles 712 are used to spray the cleaning liquid evenly on the top of the photovoltaic panel body 5, and at the same time, they work with the cleaning brush 707 to achieve further cleaning. A water injection pipe 713 is fixedly connected to the top of the water storage tank 708. The water injection pipe 713 is used to inject cleaning fluid into the interior of the water storage tank 708 for cleaning and storage.

[0024] In Embodiment 2, when dust or impurities accumulate on the top of the photovoltaic panel body 5, the drive motor 706 is turned on to drive the drive rod 702 to rotate. Then, through the meshing of the first bevel gear 704 and the second bevel gear 705, the two lead screws 703 are driven to rotate. When the lead screws 703 rotate, the cleaning brush 707 slides longitudinally on the top of the photovoltaic panel body 5. At the same time, the water pump 709 inside the water storage tank 708 is started to pump the cleaning liquid inside the water storage tank 708 into the hose 710, and then spray it out from the nozzle 712 through the drain pipe 711. This, together with the movement of the cleaning brush 707, cleans the top of the photovoltaic panel body 5.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
