Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation equipment, in particular to a rotating tracking linkage type photovoltaic power generation device. BACKGROUND

[0002] With the transformation of global energy structure to clean energy, photovoltaic power generation has become the core direction of renewable energy utilization due to its abundant resources and zero emission characteristics. The photoelectric conversion efficiency of photovoltaic panels is closely related to the incident angle of sunlight. When the sunlight is perpendicular to the surface of the photovoltaic panel, the energy absorption efficiency is the highest.

[0003] In the prior art, photovoltaic panels are mostly fixedly installed or adjusted manually, which has significant technical limitations.

[0004] Firstly, the fixedly installed photovoltaic panels can only obtain approximately perpendicular sunlight in a specific period (such as noon), and the power generation efficiency is greatly reduced in other periods due to the deviation of the incident angle.

[0005] Secondly, although some simple tracking devices can realize angle adjustment, they rely on manual periodic calibration and cannot respond to real-time changes in the position of the sun.

[0006] Therefore, in view of the problem that photovoltaic panels in the prior art are mostly fixedly installed or adjusted manually, affecting the energy absorption efficiency, it is urgent to develop a photovoltaic power generation device capable of real-time tracking of the position of the sun. SUMMARY

[0007] Therefore, the present application provides a rotating tracking linkage type photovoltaic power generation device to solve the problem that photovoltaic panels in the prior art are mostly fixedly installed or adjusted manually, affecting the energy absorption efficiency.

[0008] The present application provides a rotating tracking linkage type photovoltaic power generation device, comprising: a chassis; a support seat fixed on the upper side of the chassis, wherein a through slot is arranged on the support seat; a support disc rotatably arranged in the through slot of the support seat; a rotating assembly connected with the support seat and the support disc, wherein the rotating assembly is configured to drive the support disc to rotate in the through slot of the support seat; a photovoltaic assembly arranged on the upper side of the support disc; a locking assembly comprising a moving part and a locking part, wherein the moving part is arranged on the support seat, and the locking part is movably arranged on the support disc; The moving part is configured to drive the locking part to lock the support disc and the photovoltaic assembly.

[0009] a chassis;

[0010] a support base fixed on the upper side of the chassis, a through slot being provided on the support base;

[0011] a support disc rotatably arranged in the through slot of the support base;

[0012] a rotating assembly connected with the support base and the support disc, the rotating assembly being configured to drive the support disc to rotate in the through slot of the support base;

[0013] a photovoltaic assembly arranged on the upper side of the support disc;

[0014] a locking assembly comprising an action member and a locking member, the action member being arranged on the support base, and the locking member being movably arranged on the support disc;

[0015] the action member being configured to drive the locking member to lock the support disc and the photovoltaic assembly.

[0016] The rotating tracking linkage photovoltaic power generation device realizes efficient tracking and convenient fixing of the photovoltaic panel through the cooperative design of the chassis, the support base, the support disc, the rotating assembly, the photovoltaic assembly and the locking assembly. Specifically, the chassis serves as the basis of the device and provides a stable mounting platform for the support base, ensuring the stability of the overall structure in an outdoor environment; the support base forms rotational constraint on the support disc through the through slot, and the matching structure of the inner wall of the through slot and the edge of the support disc ensures that the support disc can freely rotate and limits its axial displacement, forming reliable rotational support. The rotating assembly connects the support base and the support disc and transmits power to the support disc through the built-in power device: when it is necessary to adjust the angle of the photovoltaic assembly, the rotating assembly starts after receiving the control signal, drives the support disc to rotate around the central axis in the through slot of the support base, and then drives the photovoltaic assembly on the upper side to rotate synchronously, realizing real-time tracking of the solar azimuth. In the locking assembly, the action member is installed at a predetermined position of the support base, and the locking member is movably arranged on the support disc through a sliding or telescopic structure. When the photovoltaic assembly is placed on the support disc, the action member starts and acts on the locking member, pushing the connection part of the locking member and the photovoltaic assembly to connect, realizing the rigid fixing of the photovoltaic assembly and the support disc; when it is necessary to disassemble, the action member reverses and releases the fixing. In this structure, the rotating assembly drives the support disc to drive the photovoltaic assembly to track the solar azimuth in real time, so that the photovoltaic assembly maintains the perpendicular incidence angle with sunlight for a longer period of time, and the locking assembly automatically operates the locking member through the action of the action member, replacing the cumbersome steps of traditional bolt fixing, so that the installation or disassembly of the photovoltaic assembly does not need to rely on external tools.

[0017] In an alternative embodiment, the rotating assembly comprises:

[0018] a bearing frame fixed on the bottom of the support base;

[0019] A support rod is rotatably arranged at the bottom end of the carrier frame and fixed at the top end of the support disc;

[0020] A driving member is fixed at the fixed end of the carrier frame;

[0021] A shaft is fixed at the driving end of the driving member;

[0022] The support rod and the shaft are connected through a gear set.

[0023] The coordinated design of the carrier frame, the support rod, the driving member and the shaft in the rotating assembly provides power transmission and structural support for the stable rotation of the support disc. The carrier frame, as the installation base of the rotating assembly, is fixed at the bottom of the support base to provide stable support for the driving member and the support rod. The bottom end of the support rod is rotatably connected to the carrier frame through a bearing with a seat, and the top end is rigidly fixed to the center position of the bottom of the support disc to form the rotating shaft of the support disc. The fixed end of the driving member (such as a motor) is fastened to the side wall of the carrier frame, and the driving end is rigidly connected to one end of the shaft. The other end of the shaft is drivingly connected to the support rod through a gear set. When the driving member is started, the shaft rotates with the driving end, and the support rod is driven to rotate synchronously through the meshing action of the gear set, thereby driving the support disc to rotate around the shaft axis in the through slot of the support base to realize the angle adjustment of the photovoltaic module.

[0024] In an alternative embodiment, the gear set comprises:

[0025] A first gear is fixed at the end of the shaft;

[0026] A second gear is fixed on the side of the support rod, and the first gear is meshed with the second gear.

[0027] In an alternative embodiment, the action member comprises:

[0028] A jacking member is connected to the support base;

[0029] A biasing member is connected to the support base, the driving end of the biasing member is located on the upper side of the jacking member, and the biasing end of the biasing member is in abutment with the locking member;

[0030] The jacking member is configured to force the biasing member to push the locking member to lock the support disc and the photovoltaic module.

[0031] The jacking member (such as an electric push rod or a hydraulic rod) is vertically installed at the predetermined installation position of the support base, and the top end thereof is in contact with the bottom of the driving end of the biasing member. The fixed end of the biasing member is hingedly connected to the support base, the driving end is located directly above the jacking member, and the biasing end is in abutment with the force receiving end of the locking member through a roller or an arc-shaped contact surface.

[0036] The support plate is vertically welded or bolted to the top surface of the support base, serving as the installation reference of the pressing plate. The middle part of the pressing plate is hinged to the support plate via the torsion spring shaft, forming a lever structure that can rotate around the hinge point. One end (the power end) of the pressing plate extends directly above the jacking member, and the other end (the action end) is in contact with the force receiving surface of the locking member. One end of the torsion spring of the torsion spring shaft is fixed to the support plate, and the other end is connected to the pressing plate. In the natural state, the initial pressure on the locking member is exerted by the pre-tightening force of the torsion spring. When the jacking member extends upward, the top end pushes the power end of the pressing plate upward, causing the pressing plate to rotate around the torsion spring shaft and further store energy in the torsion spring. The pressure on the locking member increases with the rotation angle, forcing the locking member to move towards the photovoltaic module and complete the locking. After the jacking member retracts, the locking member is unlocked. The action end of the pressing plate is provided with a pressing wheel.

[0039] a guide rail arranged in the ring-shaped support groove, and the guide block is slidingly arranged with the guide rail.

[0040] The ring-shaped support groove of the support base is circumferentially arranged on the support disc, and the guide rail is embedded in the inner side wall or the bottom of the ring-shaped support groove, forming a ring-shaped guide structure concentric with the support disc. The guide block is provided with a sliding groove matched with the guide rail, and is installed in the ring-shaped support groove through the sliding cooperation of the sliding groove and the guide rail. The jacking member is vertically fixed on the upper surface of the guide block and can move along the ring-shaped track with the guide block. When it is necessary to adjust the action position of the locking member to adapt to photovoltaic modules of different specifications, the guide block can slide along the guide rail in the ring-shaped support groove, driving the jacking member to move synchronously, so that the force of the biasing member can accurately act on the corresponding force receiving point of the locking member.

[0045] a slide rod, which is fixed in a slide groove on the support disc;

[0046] a connecting plate, which is fixed at the bottom of the wedge-shaped plate and is arranged in the slide groove and in sliding connection with the slide rod.

[0047] The wedge-shaped plate is in sliding connection with the slide groove of the support disc through the connecting plate at the bottom, the slope surface on the top surface of the wedge-shaped plate is in contact with the action member (such as the acting end of the pressing plate), and the clamping plate is fixed on the side of the wedge-shaped plate close to the photovoltaic module; the slide rod is fixed along the length direction of the slide groove, the through hole in the middle of the connecting plate is in sliding connection with the slide rod, and the wedge-shaped plate is limited to move only along the direction of the slide rod.

Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0093] With the transformation of global energy structure to clean energy, photovoltaic power generation has become the core direction of renewable energy utilization due to its abundant resources and zero emission characteristics. The photoelectric conversion efficiency of photovoltaic panels is closely related to the incident angle of sunlight. When the sunlight is perpendicular to the surface of the photovoltaic panel, the energy absorption efficiency is the highest.

[0094] In the prior art, photovoltaic panels are mostly fixedly installed or adjusted manually, which has significant technical limitations:

[0095] Firstly, the fixedly installed photovoltaic panel can only obtain approximately perpendicular sunlight in a specific period (such as noon), and the power generation efficiency is greatly reduced in other periods due to the deviation of the incident angle;

[0096] Secondly, although some simple tracking devices can realize angle adjustment, they rely on manual regular calibration and cannot respond to real-time changes in the position of the sun.

[0097] Therefore, in view of the problem that the photovoltaic panels in the prior art are mostly fixedly installed or adjusted manually, which affects the energy absorption efficiency, it is urgent to develop a photovoltaic power generation device capable of realizing real-time tracking of the position of the sun.

[0098] Embodiments of the present application will be described below with reference to Figures 1 to 3

[0099] According to the embodiments of the present application, a rotating tracking linkage photovoltaic power generation device is provided, comprising a chassis, a support base 2, a support disc 4, a rotating assembly, a photovoltaic assembly and a locking assembly. The support base 2 is fixed on the upper side of the chassis, and a through slot is arranged on the support base 2. The support disc 4 is rotatably arranged in the through slot of the support base 2. The rotating assembly is connected with the support base 2 and the support disc 4, and is configured to drive the support disc 4 to rotate in the through slot of the support base 2. The photovoltaic assembly is arranged on the upper side of the support disc 4. The locking assembly comprises an action member and a locking member. The action member is arranged on the support base 2, and the locking member is movably arranged on the support disc 4. The action member is configured to drive the locking member to lock the support disc 4 and the photovoltaic assembly.

[0100] The rotating tracking linkage photovoltaic power generation device realizes efficient tracking and convenient fixing of the photovoltaic panel 21 through the cooperative design of the chassis, the support base 2, the support disc 4, the rotating assembly, the photovoltaic assembly and the locking assembly. Specifically, the chassis serves as the basis of the device, providing a stable mounting platform for the support base 2 and ensuring the stability of the overall structure in outdoor environments. The support base 2 forms rotational constraint on the support disc 4 through the through slot. The matching structure between the inner wall of the through slot and the edge of the support disc 4 ensures that the support disc 4 can freely rotate while limiting its axial displacement, forming reliable rotational support. The rotating assembly connects the support base 2 and the support disc 4 and transmits power to the support disc 4 through the built-in power device. When the angle of the photovoltaic assembly needs to be adjusted, the rotating assembly starts after receiving the control signal, drives the support disc 4 to rotate around the central axis in the through slot of the support base 2, and then drives the photovoltaic assembly on the upper side to rotate synchronously, realizing real-time tracking of the solar azimuth. In the locking assembly, the action member is installed at a predetermined position of the support base 2, and the locking member is movably arranged on the support disc 4 through a sliding or telescopic structure. When the photovoltaic assembly is placed on the support disc 4, the action member starts and acts on the locking member, pushing the connection part of the locking member and the photovoltaic assembly to connect, realizing the rigid fixing of the photovoltaic assembly and the support disc 4. When disassembly is needed, the action member reverses and releases the fixing.

[0101] In this structure, the rotating assembly drives the support disc 4 to drive the photovoltaic assembly to track the solar azimuth in real time, so that the photovoltaic assembly maintains the perpendicular incidence angle with sunlight for a longer period of time. The automatic operation of the locking assembly through the action member to drive the locking member replaces the cumbersome steps of traditional bolt fixing, so that the installation or disassembly of the photovoltaic assembly does not need to rely on external tools.

[0102] ​In one embodiment, the rotating assembly comprises a carrier 5, a support rod 10, a driving member 6 and a shaft 7. The carrier 5 is fixed at the bottom of the support base 2; the bottom end of the support rod 10 is rotatably connected with the carrier 5, and the top end is fixed with the support disc 4; the fixed end of the driving member 6 is fixed with the carrier 5; the driving end of the shaft 7 is fixed with the driving member 6; wherein the support rod 10 and the shaft 7 are connected through a gear set.

[0103] The coordinated design of the carrier 5, the support rod 10, the driving member 6 and the shaft 7 in the rotating assembly provides power transmission and structural support for the stable rotation of the support disc 4. The carrier 5, as the installation base of the rotating assembly, is fixed at the bottom of the support base 2, providing stable support for the driving member 6 and the support rod 10. The bottom end of the support rod 10 is rotatably connected with the carrier 5 through a bearing 18, and the top end is rigidly fixed with the center position of the bottom of the support disc 4, forming the rotation axis of the support disc 4. The fixed end of the driving member 6 (such as a motor) is fastened with the side wall of the carrier 5, and the driving end is rigidly connected with one end of the shaft 7. The other end of the shaft 7 is drivingly connected with the support rod 10 through a gear set. When the driving member 6 is started, the shaft 7 rotates with the driving end, driving the support rod 10 to rotate synchronously through the meshing action of the gear set, and further driving the support disc 4 to rotate around the axis of the support rod 10 in the through slot of the support base 2, realizing the angle adjustment of the photovoltaic module.

[0104] In the above embodiment, the gear set comprises a first gear 8 and a second gear 9: the first gear 8 is fixed with the end of the shaft 7; the second gear 9 is fixed on the side of the support rod 10, and the first gear 8 is engaged with the second gear 9. The first gear 8 is fixed on the end of the shaft 7 away from the driving member 6 by key connection or welding, and rotates synchronously with the shaft 7; the second gear 9 is concentrically sleeved and fixed on the side of the support rod 10, and the teeth of the second gear 9 are engaged with the teeth of the first gear 8.

[0105] In one embodiment, the action member comprises a jacking member 15 and a biasing member: the jacking member 15 is connected with the support base 2; the biasing member is connected with the support base 2, the driving end of the biasing member is above the jacking member 15, and the biasing end of the biasing member abuts against the locking member; the jacking member 15 is configured to force the biasing member to push the locking member to lock the support disc 4 and the photovoltaic module.

[0106] The jacking member 15 (such as an electric push rod or a hydraulic rod) is vertically installed at the preset installation position of the support base 2, and the top end is in contact with the bottom of the driving end of the biasing member; the fixed end of the biasing member is hinged with the support base 2, and the driving end is located directly above the jacking member 15, and the biasing end abuts against the force receiving end of the locking member through a roller or an arc contact surface. When locking is needed, the jacking member 15 is powered on and stretched upwards, the top end pushes the driving end of the biasing member, and then forces the biasing end of the biasing member to abut against the locking member.

[0107] In the above embodiment, the biasing member includes the support plate 16, the pressing plate 17, and the torsion spring pivot 20. The support plate 16 is vertically fixed on the support base 2. The middle part of the pressing plate 17 is hinged to the support plate 16. One end of the pressing plate 17 is located on the upper side of the jacking member 15. The other end of the pressing plate 17 is in abutment with the locking member. The torsion spring pivot 20 is arranged at the connection between the support plate 16 and the pressing plate 17.

[0108] The support plate 16 is vertically welded or bolted to the top surface of the support base 2, serving as the installation reference of the pressing plate 17. The middle part of the pressing plate 17 is hinged to the support plate 16 through the torsion spring pivot 20, forming a lever structure that can rotate around the hinge point. One end (the power end) of the pressing plate 17 extends directly above the jacking member 15. The other end (the action end) of the pressing plate 17 is in contact with the force receiving surface of the locking member. One end of the torsion spring of the torsion spring pivot 20 is fixed to the support plate 16. The other end of the torsion spring is connected to the pressing plate 17. In the natural state, the action end of the pressing plate 17 exerts an initial pressure on the locking member through the pre-tightening force of the torsion spring. When the jacking member 15 extends upward, the top end of the jacking member 15 pushes the power end of the pressing plate 17 upward, causing the pressing plate 17 to rotate around the torsion spring pivot 20 and further store energy in the torsion spring. The pressure of the action end on the locking member increases with the rotation angle, forcing the locking member to move towards the photovoltaic module and complete the locking. After the jacking member 15 retracts, the locking member is unlocked. The action end of the pressing plate 17 is rotatably provided with the pressing wheel 19.

[0109] In one embodiment, the action member further includes the guide block 13 and the guide rail 12. The guide block 13 is slidingly arranged in the annular support groove 11 on the support base 2. The jacking member 15 is fixed on the upper side of the guide block 13. The guide rail 12 is arranged in the annular support groove 11. The guide block 13 is slidingly arranged with the guide rail 12.

[0110] The annular support groove 11 of the support base 2 is circumferentially formed along the support disc 4. The guide rail 12 is embedded in the inner side wall or the bottom of the annular support groove 11, forming a ring-shaped guide structure concentric with the support disc 4. The bottom of the guide block 13 is provided with a sliding groove matched with the guide rail 12. The guide block 13 is installed in the annular support groove 11 through the sliding cooperation of the sliding groove and the guide rail 12. The jacking member 15 is vertically fixed on the upper surface of the guide block 13 and can move along the annular track with the guide block 13. When it is necessary to adjust the action position of the locking member to adapt to photovoltaic modules of different specifications, the guide block 13 can slide along the guide rail 12 in the annular support groove 11, driving the jacking member 15 to move synchronously, so that the force of the biasing member can accurately act on the corresponding force receiving point of the locking member.

[0111] In one embodiment, the annular support groove 11 is arranged outside the through groove.

[0112] The through slot is located in the middle of the support base 2 as a rotating channel of the support disc 4, and the annular support groove 11 is concentrically arranged outside the support base 2 with the through slot as the center, and the two are separated by the solid structure of the support base 2 to form independent functional spaces. This layout makes the sliding mechanism composed of the guide block 13 and the guide rail 12 avoid the rotating range of the support disc 4, avoiding the spatial interference between the moving part and the support disc 4 in the movement process; at the same time, the annular support groove 11 outside provides more abundant installation space for the guide block 13, and multiple moving parts can be arranged in the circumferential direction according to the locking requirement, ensuring that the locking force is uniformly distributed in the circumferential direction of the photovoltaic module.

[0113] In one embodiment, the locking part includes a wedge-shaped plate 27, a clamping plate 28, a sliding rod 25, and a connecting plate 26: the wedge-shaped plate 27 is in sliding connection with the support disc 4, and a slope surface is arranged on the wedge-shaped plate 27, and the moving part acts on the slope surface; the clamping plate 28 is connected with the wedge-shaped plate 27, and the clamping plate 28 is suitable for fixing the photovoltaic module; the sliding rod 25 is fixed in the sliding groove on the support disc 4; and the connecting plate 26 is fixed at the bottom of the wedge-shaped plate 27 and is arranged in the sliding groove and in sliding connection with the sliding rod 25.

[0114] The wedge-shaped plate 27 is in sliding connection with the sliding groove of the support disc 4 through the connecting plate 26 at the bottom, the slope surface on the top surface of the wedge-shaped plate 27 is in contact with the moving part (such as the acting end of the pressing plate 17), and the clamping plate 28 is fixed to one side of the wedge-shaped plate 27 close to the photovoltaic module; the sliding rod 25 is fixed along the length direction of the sliding groove, the through hole in the middle of the connecting plate 26 is in sliding sleeve connection with the sliding rod 25, and the wedge-shaped plate 27 is limited to move only in the direction of the sliding rod 25. When the moving part applies pressure to the slope surface of the wedge-shaped plate 27, the wedge-shaped plate 27 is pushed to move in the direction of the photovoltaic module along the sliding rod 25, and the clamping plate 28 moves synchronously with the wedge-shaped plate 27 and clamps the photovoltaic module.

[0115] In one embodiment, the photovoltaic module includes a positioning seat 24, a support plate 22, a photovoltaic plate 21, a light sensor 29, and a controller 30: the positioning seat 24 is arranged on the support disc 4, and a positioning groove is arranged on the positioning seat 24 and is suitable for the clamping plate 28; the support plate 22 is fixed to the upper side of the positioning seat 24; the photovoltaic plate 21 is arranged on the upper side of the wedge-shaped plate 27 and is fixed between the support plate 22 and the vertical plate 23; the light sensor 29 is fixed to the side wall of the photovoltaic plate 21; and the controller 30 is in electrical connection with the rotating assembly.

[0116] The positioning seat 24 is fixed on the surface of the support disc 4, and the size and shape of the positioning groove are matched with the clamping plate 28. When the clamping plate 28 moves under the driving of the locking part, the clamping plate 28 can be embedded into the positioning groove to form a rigid connection, so that the photovoltaic module is firmly fixed with the support disc 4. The support plate 22 is vertically fixed on the upper side of the positioning seat 24, and is connected with the bottom of the photovoltaic plate 21 through the vertical plate 23, so as to provide stable support for the photovoltaic plate 21 and form a certain installation angle. The light sensor 29 is installed on the side wall of the photovoltaic plate 21, and can monitor the incident angle and intensity of sunlight in real time, and transmit the data to the controller 30. The controller 30 sends a control signal to the rotating assembly according to the detection data of the light sensor 29, drives the support disc 4 to rotate, and makes the photovoltaic plate 21 always face the incident direction of sunlight.

[0117] In one embodiment, the chassis comprises a mounting seat 1 and a plurality of bearing plates 3. The bearing plates 3 are vertically fixed on the mounting seat 1, and the top ends of the bearing plates 3 are fixed with the support seat 2.

[0118] The mounting seat 1 serves as a bearing base of the chassis, and is directly in contact with the ground or a mounting platform, and is fixed through ground bolts or other connecting parts. The plurality of bearing plates 3 vertically extend along the edges of the mounting seat 1, and the top ends are fixed with the preset positions on the bottom of the support seat 2 through welding or bolt fastening, so as to form a triangular or rectangular stable support structure. This layout makes the load borne by the support seat 2 (including the weight of the photovoltaic module, the rotating assembly and the like) uniformly transmitted to the mounting seat 1 through the bearing plates 3, and then dispersed to the foundation by the mounting seat 1.

[0119] A specific working method of the rotating tracking linkage type photovoltaic power generation device provided in the embodiment is as follows:

[0120] The positioning seat 24 is placed on the support disc 4, and the clamping plate 28 is clamped into the clamping groove on the positioning seat 24 by turning over the pressing plate 17 around the support plate 16 through starting the lifting part 15 to move upward, so as to realize the installation and fixation of the photovoltaic plate 21. The light sensor 29 installed on the side wall of the photovoltaic plate 21 detects the position of the sun and feeds back to the controller 30. The controller 30 receives the signal to encode and control the driving part 6 to start. The shaft 7 is driven to rotate by starting the driving part 6, and the first gear 8 is engaged with the second gear 9 to rotate, so as to realize the rotation of the support rod 10. The support rod 10 drives the support disc 4 to rotate, so as to realize the angular deviation of the photovoltaic plate 21. The guide block 13 rotates in the guide rail 12 to ensure the rotation of the pressing plate 17 when the support disc 4 rotates.

[0121] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
