Description

Technical Field

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

[0002] With the transformation of the global energy structure, solar photovoltaic power generation has been widely used as a clean and renewable energy form. As a key component of the photovoltaic power generation system, the performance of photovoltaic brackets directly affects the power generation efficiency and service life of photovoltaic modules. At present, the mainstream photovoltaic brackets are mainly divided into two categories: fixed brackets and tracking brackets. Among them, single-axis tracking brackets have become the mainstream choice in the market due to their high cost performance and significant power generation improvement effect.

[0003] However, traditional single-axis photovoltaic brackets can only adjust the angle in a single direction (usually east-west), and cannot adjust the vertical direction according to the change of the solar altitude angle. This results in the power generation efficiency of photovoltaic modules being limited in areas where the solar altitude angle changes greatly (such as high latitudes or when the seasons change). Although dual-axis tracking brackets can adjust the azimuth and altitude angles at the same time, their complex structure, high cost, and difficult maintenance make them difficult to promote on a large scale.

[0004] In recent years, some studies have attempted to achieve the multi-angle adjustment function of a single-axis bracket through structural improvements. For example, by adding a lifting mechanism or an articulated structure to the bracket, a certain degree of vertical angle adjustment can be achieved. However, these solutions usually require additional drive devices and complex control systems, which increase costs, and in practical applications, there are problems such as poor stability and insufficient wind resistance. In addition, the prior art lacks a solution that can be improved on the basis of the existing single-axis bracket at a low cost to achieve angle adjustment in the second direction.

[0005] Therefore, there is an urgent need for a technical solution with a simple structure, low cost and easy promotion, which can achieve angle adjustment in the second direction through local structural improvements on the basis of the existing single-axis photovoltaic bracket, thereby further improving the power generation efficiency of the photovoltaic system without significantly increasing equipment investment. Summary of the invention

[0006] In view of this, the present invention proposes a connector that can be used for a single-axis photovoltaic bracket, so as to achieve elevation adjustment in the north-south direction.

[0007] The technical solution of the present invention is implemented as follows: The present invention provides a connector for a photovoltaic bracket, including: a bottom sleeve, a top sleeve, a lifter, a support platform and a bearing seat. The bottom of the bottom sleeve is open and is used to be sleeved and fixed on the photovoltaic bracket. The top of the bottom sleeve is fixedly provided with a lifter. The bottom of the top sleeve is open, and the top sleeve is coaxially sleeved above the bottom sleeve. The driving end of the lifter is abutted against the top surface of the bottom opening of the top sleeve. The lifter can drive the top sleeve to reciprocate linearly relative to the bottom sleeve in the vertical direction. The top of the top sleeve is hinged to the bottom of the support platform through a hinge shaft. A bearing seat is fixed to the top of the support platform. The axis of the hinge shaft between the top sleeve and the support platform and the axis of the bearing seat are perpendicular to each other.

[0008] In some embodiments, the lifter is a motor driven scissor lifter.

[0009] In some embodiments, a buffer spring is further included, which is arranged between the bottom of the support platform and the top of the top sleeve, the axis of the buffer spring is arranged vertically, and the axis of the buffer spring is spaced apart from the axis of the hinge shaft between the top sleeve and the support platform.

[0010] In some embodiments, the number of the buffer springs is two, and the two buffer springs are arranged in an array and spaced apart along the axis direction of the bearing seat.

[0011] In some embodiments, the outer side surface of the bottom sleeve fits with the inner surface of the top sleeve, and lubrication is provided between the outer side surface of the bottom sleeve and the inner surface of the top sleeve.

[0012] In some embodiments, the bottom opening of the top sleeve is polygonal.

[0013] In some embodiments, a first hinge seat is provided at the top of the top sleeve, and a second hinge seat is provided at the bottom of the support platform, and the first hinge seat and the second hinge seat are hingedly connected via a hinge shaft.

[0014] In some embodiments, the hinge hole on the first hinge seat or the second hinge seat is a waist-shaped hole, and the long axis of the waist-shaped hole is arranged along the vertical direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The connector for the photovoltaic bracket provided by the present invention can adopt a lifter in conjunction with an articulated shaft to achieve height adjustment of the support platform. When the support platforms located at both ends of the single axis change in height, the elevation angle can be adjusted, thereby adapting to changes in the altitude angle of the sun. Compared with traditional single-axis brackets, the present application can achieve angle adjustment in the second direction based on existing equipment, significantly improving the power generation efficiency of the photovoltaic system.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0024] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] like Figure 1 As shown, combined Figure 2-3 The connector for a photovoltaic bracket of the present invention includes: a bottom sleeve 1, a top sleeve 2, a lifter 3, a support platform 4 and a bearing seat 5. The bottom of the bottom sleeve 1 is open and is used to be sleeved and fixed on the photovoltaic bracket. The top of the bottom sleeve 1 is fixedly provided with a lifter 3. The bottom of the top sleeve 2 is open, and the top sleeve 2 is coaxially sleeved above the bottom sleeve 1. The driving end of the lifter 3 is abutted against the top surface of the bottom opening of the top sleeve 2. The lifter 3 can drive the top sleeve 2 to reciprocate linearly relative to the bottom sleeve 1 in the vertical direction. The top of the top sleeve 2 is hinged to the bottom of the support platform 4 through a hinge shaft. A bearing seat 5 is fixed to the top of the support platform 4. The axis of the hinge shaft between the top sleeve 2 and the support platform 4 and the axis of the bearing seat 5 are perpendicular to each other.

[0027] The connector for the photovoltaic bracket is used to support the rotating shaft and the photovoltaic panel installed on the rotating shaft. Conventional connectors usually only have one bearing seat. When driven by an external driving device, the rotating shaft rotates, thereby realizing unidirectional rotation adjustment of the photovoltaic panel. In the above embodiment, by arranging a lifter 3 and two sets of sleeve structures in the connector, the height adjustment of the bearing seat 5 located on the supporting platform 4 is realized. When the heights of the bearing seats 5 on the two connectors on both sides of the rotating shaft change in opposite directions, the elevation angle of the photovoltaic panel in another set of directions can be adjusted.

[0028] Due to the modular design of the bottom sleeve 1, the top sleeve 2 and the lifter 3, there is no need to carry out large-scale transformation of the existing single-axis support, thereby reducing the equipment investment cost.

[0029] In some embodiments, the lifter 3 is a motor driven scissor lifter.

[0030] In the above embodiments, the lifter 3 is preferably a motor-driven scissor fork lifter, which has the characteristics of compact structure and high driving efficiency, and further reduces the manufacturing cost and maintenance cost.

[0031] In some embodiments, a buffer spring 6 is also included, which is arranged between the bottom of the support platform 4 and the top of the top sleeve 2. The axis of the buffer spring 6 is vertically arranged, and the axis of the buffer spring 6 is spaced apart from the axis of the hinge shaft between the top sleeve 2 and the support platform 4.

[0032] In the above embodiments, the buffer spring 6 is used to assist in providing additional supporting force, thereby counteracting the weight of the components above the support platform 4 and avoiding a large load on the hinge shaft. The setting of the buffer spring 6 effectively reduces the vibration and impact during the lifting process and enhances the stability and durability of the structure.

[0033] In some embodiments, the number of the buffer springs 6 is two, and the two buffer springs 6 are arranged in an array and spaced apart along the axial direction of the bearing seat 5 .

[0034] In the above embodiment, the two buffer springs 6 are symmetrically arranged, so as to support the bottom of the support platform 4 on both sides of the hinge axis, so that the forces on both sides of the support platform 4 are uniform.

[0035] In some embodiments, the outer side surface of the bottom sleeve 1 fits with the inner surface of the top sleeve 2 , and lubrication is provided between the outer side surface of the bottom sleeve 1 and the inner surface of the top sleeve 2 .

[0036] In the above embodiments, the bottom sleeve and the top sleeve are designed with lubrication, which reduces friction loss and prolongs the service life.

[0037] In some embodiments, the bottom opening of the top sleeve 2 is polygonal.

[0038] In the above embodiments, the bottom opening of the top sleeve 2 is designed to be polygonal (such as square or hexagonal), which cooperates with the non-cylindrical sleeve to improve the wind load resistance and guiding accuracy.

[0039] In some embodiments, a first hinge seat 21 is provided at the top of the top sleeve 2, and a second hinge seat 41 is provided at the bottom of the support platform 4. The first hinge seat 21 and the second hinge seat 41 are hingedly connected via a hinge shaft.

[0040] In the above embodiments, the first hinge seat 21 and the second hinge seat 41 are hinged to ensure a certain spacing distance between the support platform 4 and the top sleeve 2, thereby being able to adapt to a larger angle adjustment and effectively avoiding collision and interference between the support platform 4 and the top sleeve 2 during the angle adjustment process.

[0041] In some embodiments, the hinge hole on the first hinge seat 21 or the second hinge seat 41 is a waist-shaped hole, and the long axis of the waist-shaped hole is arranged along the vertical direction.

[0042] In the above embodiments, the waist-shaped hole design of the articulated seat allows for fine adjustment of the angle within a certain range, which facilitates installation and calibration and reduces the difficulty of construction.

[0043] This solution can be directly applied to existing single-axis photovoltaic brackets without replacing the entire bracket system. It is suitable for large-scale promotion. The modular design facilitates mass production and transportation and is applicable to various photovoltaic projects (such as ground power stations, distributed roofs, etc.).

[0044] The photovoltaic bracket connector of the present invention realizes a low-cost, high-efficiency multi-angle adjustment function through an innovative structural design, significantly improving the power generation efficiency and stability of the photovoltaic system. Its modular design and intelligent expansion potential make it have a wide range of application prospects and suitable for promotion and use in existing photovoltaic systems.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
