Description

Technical Field

[0001] This invention relates to solar photovoltaic panel supports, and in particular to a single-axis inclined solar photovoltaic panel tracking support. Background Technology

[0002] As a support system for solar photovoltaic panels, the solar photovoltaic panel tracking bracket needs to provide tilted support for the panels and also have a tracking and deflecting function towards the sun. Existing solar photovoltaic panel tracking brackets typically consist of a base bracket and a drive mechanism. The top surface of the bracket is tilted 25° southward towards the sunlight. The drive mechanism, located at the southern end of the base bracket, includes a motor and a reducer, which drives the entire bracket to deflect. Existing solutions have a low torsional natural frequency and a low critical wind speed. When the wind speed exceeds the critical wind speed, the bracket system is prone to vibration, and the worm gear of the reducer is more susceptible to fatigue and damage, which is detrimental to the normal operation of the reducer. Furthermore, the existing brackets have a large chord length, resulting in a linear increase in the vertical load on the square tube and a square-fold increase in torque. Therefore, the main beam of the square tube must meet certain cross-sectional dimensions and material strength requirements. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a single-axis inclined solar photovoltaic panel tracking bracket with a stable bracket system structure and a drive mechanism that is not easily damaged.

[0004] The technical problem solved by this invention is achieved through the following technical solution:

[0005] A single-axis inclined solar photovoltaic panel tracking bracket is characterized by comprising a main beam and a support frame, wherein the support frame is fixedly installed on the upper part of the main beam; a front bushing is installed at the front end of the main beam, and the front bushing is fixedly installed on a front support pier; a rear bushing is installed at the rear end of the main beam, and the rear bushing is fixedly installed on the top of a pair of inclined support columns, the bottom ends of the pair of inclined support columns are fixedly installed on a pair of rear support piers; an inclined tie bracket is installed between the upper part of the main beam and the support frame, the upper end of a lead screw is hinged on the inclined tie bracket; a motor support beam is fixedly installed between the pair of inclined support columns, and a motor reducer assembly and a lifting mechanism are installed on the motor support beam; the lower end of the lead screw is installed on the lifting mechanism, and the motor reducer drives the lifting mechanism to move the lead screw up and down; the lead screw drives the main beam and the support frame to deflect along the axis of the front bushing and the rear bushing through the inclined tie bracket.

[0006] Furthermore, the inclined support is hinged via a lead screw hinge seat.

[0007] Furthermore, the main beam is made of 130mm x 130mm square tubing with a thickness of 3mm and made of Q355B material. The main beam is fixedly connected to the crossbeams of the supporting frame by several spaced clamps.

[0008] Furthermore, the motor support rod is installed at an angle, and the direction of movement of the motor support rod is perpendicular to that of the lead screw.

[0009] Moreover, the front and rear bushings are heavy-duty bushings.

[0010] The advantages and beneficial effects of this invention are as follows:

[0011] 1. The inclined single-axis solar photovoltaic panel tracking bracket of the present invention sets the motor reducer assembly at the rear of the main beam. The main beam is driven by the lead screw and inclined bracket to drive the support frame and then drive the front and rear bushings to deflect, thereby realizing the deflection adjustment of the entire solar photovoltaic panel. The drive structure is stable and the force is more reasonable. The worm gear assembly of the motor reducer is not easy to fatigue and damage, which is conducive to normal operation.

[0012] 2. In the inclined single-axis solar photovoltaic panel tracking bracket of the present invention, the main beam and the crossbeam of the support frame are fixedly connected by several spaced clamps. The main beam is made of 130mm x 130mm / 3mm thick Q355B square tube, which has better connection strength and higher moment of inertia, torsional constant and section modulus. The increased cross-sectional size of the square tube increases the natural frequency of the bracket structure, thereby increasing the critical wind speed and reducing the risk of vibration of the bracket system.

[0013] 3. In the inclined single-axis solar photovoltaic panel tracking bracket of the present invention, the motor support rod is installed at an angle and the movement direction of the motor support rod is perpendicular to that of the lead screw, which facilitates the linear transmission of the lead screw and provides drive for pushing and pulling the inclined bracket.

[0014] 4. The inclined single-axis solar photovoltaic panel tracking bracket of the present invention has a front end bushing and a rear end bushing for rotating installation of the main beam, while preventing axial movement. A single bearing can withstand both dynamic and static loads to meet the usage requirements.

[0015] 5. The inclined single-axis solar photovoltaic panel tracking bracket of the present invention has a stable bracket system structure and the drive mechanism is not easily damaged, effectively ensuring the safe and stable operation of the solar photovoltaic panel and improving its service life.

Detailed Implementation

[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.

[0024] A single-axis inclined solar photovoltaic panel tracking bracket includes a main beam 5 and a support frame 12. The support frame is fixedly installed on the upper part of the main beam, and the main beam and the crossbeam of the support frame are fixedly connected by several spaced clamps 6. A solar photovoltaic panel 4 is fixedly installed on the upper surface of the support frame. The front end of the main beam is installed on a front bushing 3, which is fixedly installed on a front support pier 1 by a vertical support column 2. The rear end of the main beam is installed on a rear bushing 17, which is fixedly installed on the top of a pair of inclined support columns 7. The bottom ends of the pair of inclined support columns are fixedly installed on a pair of rear support piers 8. The inclined support columns are inclined backward, and at the same time, in rear view, the bottoms of the two inclined support columns are separated to both sides, so that the main beam and the support frame form an inclined solar receiving surface.

[0025] A diagonal brace 11 is installed between the upper part of the main beam and the support frame. The upper end of the lead screw 9 is hinged on the diagonal brace, which is connected by a lead screw hinge seat 10. A motor support beam 13 is fixedly installed between a pair of diagonal support columns. A motor reducer assembly and a lifting platform 14 are installed on the motor support beam. The lower end of the lead screw is installed on the lifting platform. The motor reducer assembly drives the lifting platform to move the lead screw up and down. The lead screw drives the main beam and support frame to deflect along the axis of the front and rear bushings through the diagonal brace. The motor reducer assembly consists of a linear drive motor 16 and a planetary reducer 15. The linear drive motor is a 300-watt 90-type linear drive motor with a working voltage of 24 volts. The planetary reducer is an 86PX planetary reducer with a reduction ratio of 1:20. The lifting platform is an SWL2.5T worm gear screw jack with a maximum lifting capacity of 2.5 tons.

[0026] The motor support rod is installed at an angle to ensure that the motor support rod is perpendicular to the direction of movement of the lead screw, which facilitates the linear transmission of the lead screw and provides drive for pushing and pulling the above-mentioned inclined support bracket.

[0027] The front and rear bushings are heavy-duty bushings, which are used to rotate the main beam and prevent axial movement. Each bearing can withstand 500 cycles of a 1.6T dynamic load without failure, and >210,000 cycles of a 10kN compressive load without failure. Each bearing can withstand a 57kN static load without yielding or deformation.

[0028] The working principle of this inclined single-axis solar photovoltaic panel tracking bracket is as follows:

[0029] The main beam of this inclined single-axis solar photovoltaic panel tracking bracket is made of 130mm x 130mm thick Q355B square tubing, which has better strength and features a higher moment of inertia, torsional constant, and section modulus. The increased cross-sectional size of the square tubing increases the natural frequency of the bracket structure, thereby increasing the critical wind speed and reducing the risk of vibration in the bracket system.

[0030] The motor reducer assembly is located at the rear of the main beam. Through a lead screw and diagonal brace, it drives the support frame, which in turn drives the main beam to deflect via the front and rear bushings, thus adjusting the overall deflection of the solar photovoltaic panels. The drive structure is stable, with more rational force distribution. The worm gear assembly of the motor reducer is less prone to fatigue and damage, which is beneficial for normal operation. With a ±135 degree angle and a control speed of 5 degrees per minute, it features high damping, high support strength, and high wind load resistance, enabling it to withstand category 12 typhoons.

[0031] Although the embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the invention and the appended claims. Therefore, the scope of the invention is not limited to the contents disclosed in the embodiments and drawings.
