Description

TECHNICAL FIELD

[0001] The present application relates to a photovoltaic power generation device, in particular to a multi-angle light tracking large-area photovoltaic power generation system. BACKGROUND

[0002] A solar panel is assembled by connecting a plurality of solar cells in series and parallel, each of which has a photoelectric semiconductor sheet for directly generating electricity using sunlight. When sunlight is vertically incident on the solar panel, the solar panel can obtain strong sunlight and thus convert more electrical energy, and the photoelectric conversion efficiency of the solar panel is relatively high at this time.

[0003] The angle of the conventional solar panel relative to the ground after installation is fixed. Since the angle and direction of sunlight change over time, the solar panel of the prior art can only be perpendicular to sunlight for a short period of time in a day, and cannot face the sunlight most of the time, so the photoelectric conversion efficiency is low and the power generation effect is poor. In view of this, the prior art proposes some light tracking photovoltaic power generation devices, such as a light tracking photovoltaic panel assembly disclosed in the utility model patent with the authorization announcement number CN220586216U and a self-light tracking new energy photovoltaic power generation system and light tracking method disclosed in the invention application with the application publication number CN119865117A.

[0004] However, the above light tracking photovoltaic power generation device has the following disadvantages:

[0005] 1. It is only suitable for small-area photovoltaic panels and meets the light tracking adjustment of small-area photovoltaic panels, but is not suitable for large-area photovoltaic panel arrays and needs to be improved.

[0006] 2. Since a large-area photovoltaic panel array is obtained by a plurality of photovoltaic panel arrays, if each photovoltaic panel is provided with a light tracking mechanism, the structure is complex and the cost is high. SUMMARY

[0007] The present application aims to overcome the above-mentioned problems and provide a multi-angle light tracking large-area photovoltaic power generation system, which not only has a matrix-type large-area photovoltaic panel array, but also can track light at multiple angles, has the advantages of high power generation efficiency, simple structure, and low cost.

[0008] The purpose of the present application is achieved by the following technical solutions:

[0009] A multi-angle light tracking large-area photovoltaic power generation system, comprising a photovoltaic panel array and a multi-angle light tracking support module arranged below the photovoltaic panel array.

[0010] The multi-angle light tracking support modules are arranged in a matrix, and some of the multi-angle light tracking support modules have active telescopic driving force. In the south-north light tracking state, the multi-angle light tracking support modules with active telescopic driving force responsible for south-north light tracking drive the whole photovoltaic panel square matrix to rotate around the south-north rotation center, which is composed of one group of multi-angle light tracking support modules arranged in the direction parallel to the latitude of the earth.

[0011] In the east-west light tracking state, the multi-angle light tracking support modules with active telescopic driving force responsible for east-west light tracking drive the whole photovoltaic panel square matrix to rotate around the east-west rotation center, which is composed of one group of multi-angle light tracking support modules arranged in the direction parallel to the longitude of the earth.

[0012] In one preferred embodiment of the application, the multi-angle light tracking support modules include a plurality of active light tracking support modules and a plurality of passive light tracking support modules, and the active light tracking support modules are multi-angle light tracking support modules with active telescopic driving force.

[0013] Further, the active light tracking support modules are arranged in an isosceles triangle, two base angles of the isosceles triangle are located at two corner positions of the matrix, the apex angle of the isosceles triangle is located at the center position of the edge of the matrix, and the base of the isosceles triangle is parallel to the latitude of the earth. Due to the small angle of south-north light tracking and the distribution of light tracking process throughout the year, in the south-north light tracking state, the latitude queue corresponding to the active light tracking support module at the apex angle of the isosceles triangle is taken as the south-north rotation center (i.e. one boundary of the matrix), and the other two active light tracking support modules simultaneously perform telescopic driving in the same direction, thereby driving the whole photovoltaic panel square matrix to rotate around the east-west rotation center, adjusting the posture of the photovoltaic panel square matrix to follow the direction of sunlight to obtain the best power generation efficiency. Further, due to the large angle of east-west light tracking and the daily light tracking, in the east-west light tracking state, the longitude queue corresponding to the active light tracking support module at the apex angle of the isosceles triangle is taken as the south-north rotation center (i.e. one center line of the matrix), and the other two active light tracking support modules perform telescopic driving in opposite directions, so that the two ends of the photovoltaic panel square matrix simultaneously perform reverse swinging, effectively reducing the driving range of the active light tracking support module, and making it more convenient.

[0014] In one preferred embodiment of the present application, the active light tracking support module comprises an active hydraulic cylinder, an active electromagnetic valve and a universal rotary connecting mechanism, one end of the active hydraulic cylinder is connected with the support of the photovoltaic panel square array through a universal ball structure, and the other end of the active hydraulic cylinder is hinged with the universal rotary connecting mechanism; the passive light tracking support module comprises a passive hydraulic cylinder, a passive electromagnetic valve and a universal rotary connecting mechanism, one end of the passive hydraulic cylinder is connected with the support of the photovoltaic panel square array through a universal ball structure, and the other end of the passive hydraulic cylinder is hinged with the universal rotary connecting mechanism. Through the above structure, in the east-west light tracking operation, before the sunrise, the active electromagnetic valve of the active light tracking support module corresponding to the east-west rotary center and the passive electromagnetic valve of the passive light tracking support module are controlled to enter the closed state by the control unit, the passive electromagnetic valves of other passive light tracking support modules enter the open state, and the active hydraulic cylinder of the active light tracking support module located in the east drives the corresponding end of the photovoltaic panel square array to swing downward, and the active hydraulic cylinder of the active light tracking support module located in the west drives the corresponding end of the photovoltaic panel square array to swing upward, so that the entire photovoltaic panel square array faces east to meet the sun. Similarly, in the north-south light tracking operation, the photovoltaic panel square array is driven to swing around the north-south rotary center by the corresponding active light tracking support module, and is real-time directed to the sun according to the above operation mode.

[0015] Further, the active electromagnetic valve is a three-position four-way electromagnetic valve, two ports of the three-position four-way electromagnetic valve are respectively communicated with two ends of the inner cavity of the active hydraulic cylinder, and the other two ports of the three-position four-way electromagnetic valve are communicated with the hydraulic oil supply device. By controlling the flow direction of the three-position four-way electromagnetic valve, the extension and retraction operation and the stop operation of the active hydraulic cylinder can be realized, and the requirements can be met.

[0016] Further, the active light tracking support module also comprises a passive electromagnetic valve, the passive electromagnetic valve is a two-position two-way electromagnetic valve, and two ports of the two-position two-way electromagnetic valve are respectively communicated with two ends of the inner cavity of the active hydraulic cylinder. In the non-light tracking state, the two-position two-way electromagnetic valve is in the closed state to prevent the flow of hydraulic oil, thereby realizing the rigid support; in the light tracking state, the two-position two-way electromagnetic valve is in the open state to allow the flow of hydraulic oil, and the photovoltaic panel square array is not limited to adjust the posture.

[0017] In one preferred embodiment of the present application, the universal rotary connecting mechanism comprises a protective cover, a first hinged support assembly and a second hinged support assembly.

[0018] The first hinged support assembly comprises a first support base and a first locking structure, and the second hinged support assembly comprises a second support base and a second locking structure; the first support base is fixedly connected to the bottom surface, the second support base is hingedly connected to the first support base through a first hinged shaft, and the active hydraulic cylinder or the passive hydraulic cylinder is hingedly connected to the second support base through a second hinged shaft; the first locking structure is used for locking the second support base and the first hinged shaft, and the second locking structure is used for locking the active hydraulic cylinder or the passive hydraulic cylinder and the second hinged shaft.

[0019] Further, the first locking structure and the second locking structure are the same and each comprise a fixing member, a vertical moving base, a pair of locking clamps and a locking driving member;

[0020] The fixing member is fixedly connected to the second support base; the vertical moving base is vertically movable relative to the fixing member, and two long circular holes are arranged in the vertical moving base; the pair of locking clamps are hingedly connected to the fixing member through the same hinged shaft, and an oscillating transmission part and a locking groove are arranged in the locking clamps; the oscillating transmission part extends into the long circular hole, and the first hinged shaft and the second hinged shaft are respectively located between the locking grooves of the two locking clamps; and the locking driving member is used for driving the vertical moving base to move vertically.

[0021] Further, the locking driving member is a locking driving motor, and the locking driving motor is provided with one, and an output shaft of the locking driving motor is connected with a cam; the vertical moving bases of the second locking structure and the first locking structure are located on the upper and lower sides of the cam.

[0022] The first locking structure and the second locking structure each further comprise a stretching spring, and two ends of the stretching spring are respectively abutted against the two locking clamps.

[0023] Through the above structure, if it is required to enter the locking state, the cam is driven to rotate in the corresponding direction by the locking driving motor, so that the cam performs a pushing movement, that is, the point farthest from the center of the cam gradually turns to the vertical moving base of the first locking structure and the second locking structure, thereby pushing the vertical moving base of the first locking structure to move downward (the vertical moving base of the second locking structure moves upward), so as to make the locking grooves of the two locking clamps close to the first hinged shaft (the second hinged shaft), and then hold the first hinged shaft (the second hinged shaft), and the stretching spring is compressed and deformed to store energy, at this time, the second support base, the active hydraulic cylinder or the passive hydraulic cylinder are all in the locked state, so as to stably support the photovoltaic panel square array; similarly, if it is required to enter the unlocking state, the cam is driven to rotate in the reverse direction by the locking driving motor, the stretching spring releases potential energy and restores deformation, the locking grooves of the two locking clamps are driven to move away from the first hinged shaft (the second hinged shaft), so as to realize unlocking, which is very ingenious.
