Description

Technical Field

[0001] The utility model relates to the technical field related to photovoltaic aluminum frames, and in particular to a split-type photovoltaic aluminum frame. Background Art

[0002] The solar frame plays the role of protecting the components and facilitating the connection and fixation of the components. Because solar panels are mainly composed of monocrystalline silicon or polycrystalline silicon solar cells and tempered glass, they are particularly brittle and easy to break, so they must be protected by a frame on the outside.

[0003] Solar panel frames currently available on the market come in a variety of materials, including stainless steel, aluminum alloy, rubber, and reinforced plastic. Aluminum alloy frames are the most widely used due to their simple processing, lightweight, corrosion resistance, durability, tensile strength, high metal fatigue resistance, and high elasticity and rigidity. Even scratches on the surface will not oxidize, which will not affect performance. Aluminum alloy frames have a lifespan of 30-50 years.

[0004] my country's utility model patent application number CN202122235470.4, "A split photovoltaic aluminum frame with adjustable notches", discloses a split photovoltaic aluminum frame with adjustable notches, including an aluminum frame body, an upper notch and a lower notch formed in the aluminum frame body, and the aluminum frame body is divided into a laminated part and a fixed part at the upper notch. A pressure sensor and a stud are provided at the bottom of the laminated part, and the pressure sensor is located between the laminated part and the stud. A fluorescent coloring layer is provided on the outside of the pressure sensor, and the stud is connected to the threaded hole at the top of the fixed part.

[0005] However, the above patent still has the following shortcomings: the aluminum frame body and the laminated part can only be connected by one stud, and the stud is prone to thread slippage during long-term use, which will lead to poor installation stability and low assembly strength between the two. The laminated part is easy to rotate around the axis of the stud, which is not conducive to the convenient installation of the solar panel into the slot. Therefore, it is necessary to design a split photovoltaic aluminum frame. Utility Model Content

[0024] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0025] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0026] like Figure 1-5 As shown, a split photovoltaic aluminum frame includes: a frame body 2 with a central cavity 1, a laminate 3 with an L-shaped cross section, and a plurality of mounting units arranged at intervals along the length direction of the frame body 2 and assembled in the central cavity 1;

[0027] The frame body 2 is provided with a first strip through groove with the same length direction and open at both ends connected to the middle cavity 1. The installation unit includes a clamping block 4 that can move closer to or away from the first strip through groove. The long side of the laminate 3 can slide through the first strip through groove. The long side of the laminate 3 is provided with a clamping strip portion 5 with the same length direction and can be slidably clamped into the clamping block 4.

[0028] By adjusting the distance between the clamping block 4 and the first strip-shaped through groove, the width of the slot between the end of the laminate 3 and the frame body 2 can be adjusted. The clamping strip 5 is slidably inserted into several clamping blocks 4 along the length direction. The laminate 3 and the frame body 2 do not rotate relative to each other, and the assembly stability and strength of the two are high.

[0029] At least one mounting through-slot is provided on one of the side walls of the first strip through-slot, a screw-on portion 6 is provided on the other side wall of the first strip through-slot, a mounting bolt 7 is provided on the frame body 2 and is threadedly connected to the screw-on portion 6 through the corresponding mounting through-slot, and a second strip through-slot 8 is provided on the laminate 3 for the corresponding mounting bolt 7 to pass through and the length direction of which is perpendicular to the length direction of the first strip through-slot.

[0030] The mounting bolt 7 passes through the mounting slot and is connected to the screw-on portion 6 , which can prevent the first strip slot from deforming and increasing its width. The mounting bolt 7 passes through the second strip slot 8 , which can also prevent the laminate 3 from sliding and dislocating on the frame body 2 .

[0031] The screw-on portion 6 is a strip-shaped groove with a width smaller than the diameter of the mounting bolt 7 and arranged in the same length direction as the frame body 2 , and both ends of the strip-shaped groove are open.

[0032] Since the frame body 2 is extruded during production, the screw-on portion 6 is configured as a strip-shaped groove, which is convenient for manufacturing.

[0033] The mounting unit also includes a mounting seat 9 fixedly mounted on the inner wall of the middle cavity 1 opposite to the first strip-shaped through groove, and a protrusion 10 is protruding from the mounting seat 9 and in contact with the inner wall of the middle cavity 1 opposite to the mounting seat 9, and the clamping block 4 is slidably assembled on the protrusion 10, and an adjusting bolt 11 is axially connected to the mounting seat 9, which passes through the clamping block 4 in a threaded manner and has an axial direction perpendicular to the length direction of the clamping strip 5, and a window 12 corresponding to the head of the adjusting bolt 11 is penetrated on the frame body 2.

[0034] After the mounting unit is assembled into the middle cavity 1 , a tool can be passed through the window 12 to rotate the adjusting bolt 11 , thereby driving the adjusting bolt 11 to rotate and adjust the position of the clamping block 4 . The setting of the window 12 facilitates the rotation of the adjusting bolt 11 .

[0035] The side of the clamping block 4 away from the clamping strip portion 5 is provided with a screw sleeve portion 13 connected to the adjusting bolt 11, and the side of the protrusion 10 close to the clamping block 4 is recessed to provide a sliding groove 14 for the screw sleeve portion 13 to slide, and the end of the sliding groove 14 away from the mounting seat 9 is an open end.

[0036] By rotating the adjusting bolt 11 , the threaded sleeve portion 13 can slide in the sliding groove 14 , driving the clamping block 4 to move closer to or away from the first strip-shaped through groove.

[0037] The mounting seat 9 is provided with a circular groove for accommodating the head of the adjusting bolt 11 , and a bearing 15 with an inner ring fixedly sleeved on the adjusting bolt 11 is fitted in the circular groove.

[0038] The circular groove is used to assemble the bearing 15 and to accommodate the head of the adjusting bolt 11 so as to facilitate the assembly of the mounting seat 9.

[0039] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0041] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
