Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a photovoltaic panel connection device. Background Art

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They can directly convert solar energy into electrical energy. The basic working principle of photovoltaic panels is that when solar light shines on the photovoltaic panel, photons excite photoelectrons to form an electric current.

[0003] Most of the existing photovoltaic panels are independent. Although this can reduce space occupation during transportation, it is time-consuming and labor-intensive to connect the photovoltaic panels to the brackets one by one during installation. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that although the space occupied is small, the photovoltaic panels are relatively independent and need to be installed one by one, which is relatively time-consuming and labor-intensive.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a photovoltaic panel connection device, comprising a plurality of photovoltaic panels, wherein the photovoltaic panels are all fan-shaped structures and are arranged in a circular array, and connecting sleeves are respectively connected on both sides of adjacent photovoltaic panels relative to each other, and ball joints are provided in the connecting sleeves, and connecting shafts are connected relative to the ball joints, and a positioning component for positioning the ball joints is connected to the connecting sleeves, and the positioning component can drive the photovoltaic panels to remain in the same plane.

[0008] Furthermore, the connecting sleeve is a cylindrical structure, and a cavity is provided inside the connecting sleeve to cooperate with the ball joint. The connecting sleeve is vertically connected to the plane of the photovoltaic panel and is provided with a through hole. The through hole cooperates with the connecting shaft. The connecting sleeve uses the cavity to facilitate the limiting of the ball joint and its rotation. Since the radius of the ball joint is larger than the radius of the cross-sectional plate of the connecting shaft and the setting of the through hole facilitates the rotation of the ball joint within the plane where the through hole is located, and the rotation range can reach 180°.

[0009] Furthermore, the positioning assembly includes a limit groove connected to the end of the connecting ball joint away from the connecting shaft, a accommodating cavity is connected to the middle part of the connecting sleeve, a spring is connected in the accommodating cavity, and a limit block is connected to the other end of the spring, and the limit block cooperates with the limit groove. When the end of the ball joint away from the connecting shaft is aligned with the limit block, the limit block cooperates with the limit groove under the elastic force of the spring. At this time, one end of the limit block is located in the limit groove, and the other end is located in the accommodating cavity, so that the adjacent photovoltaic panels, the limit blocks, and the connecting shaft are coplanar, thereby achieving the purpose of positioning.

[0010] Furthermore, the connecting sleeve is connected to the accommodating cavity with a sliding hole, and the limit block is connected to a driving rod, and the driving rod slides through the sliding hole. The matching setting of the sliding hole and the driving rod facilitates the driving rod to drive the limit block to move backward into the accommodating cavity by toggling the driving rod, so that the limit block and the limit groove no longer cooperate. At this time, the photovoltaic panel can be rotated again with the ball joint as the axis to achieve folding.

[0011] Furthermore, the other end of the driving rod does not extend beyond the surface of the photovoltaic panel, thereby avoiding interference between the driving rods.

[0012] Furthermore, the distance between the centers of the ball joints is not less than the thickness of the photovoltaic panel, so that adjacent photovoltaic panels can be folded to be parallel to each other and avoid forming an angle that increases the occupied space after folding.

[0013] 3. Beneficial Effects

[0014] The advantages of the utility model compared with the prior art are:

[0015] 1. The fan-shaped photovoltaic panel, connecting sleeve, ball joint and connecting shaft are arranged in a coordinated manner to facilitate folding of the photovoltaic panel, thereby reducing the occupied space for transportation;

[0016] 2. The photovoltaic panel, connecting sleeve, ball joint, connecting shaft and positioning assembly are arranged in coordination, so that the photovoltaic panel can be positioned in a plane through the positioning assembly, so as to avoid the angle change of each photovoltaic panel due to external force, thereby affecting the light gain, and the installation can be completed by positioning only one of the photovoltaic panels.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Combined with Figure 1 , Figure 2 and Figure 4 A photovoltaic panel connection device, comprising a plurality of photovoltaic panels 1, each of which is a fan-shaped structure and arranged in a circular array, and connecting sleeves 2 are respectively connected on both sides of adjacent photovoltaic panels 1, and ball joints 12 are arranged in the connecting sleeves 2, and the spacing between the centers of the ball joints 12 is not less than the thickness of the photovoltaic panel 1, and connecting shafts 3 are connected between the ball joints 12;

[0025] The coordinated arrangement of the fan-shaped photovoltaic panel 1, the connecting sleeve 2, the ball joint and the connecting shaft 3 in the above structure facilitates folding of the photovoltaic panel 1 and reduces the occupied space for transportation. The connecting sleeve 2 facilitates the limiting of the ball joint through the cavity 4 and also facilitates its rotation. Since the radius of the ball joint 12 is larger than the radius of the cross-sectional plate of the connecting shaft 3 and the arrangement of the through hole 5 facilitates the rotation of the ball joint 12 within the plane where the through hole 5 is located, the rotation range can reach 180°. The distance between the centers of the ball joints 12 is not less than the thickness of the photovoltaic panel 1, so that the adjacent photovoltaic panels 1 can be parallel to each other after folding to avoid forming an angle and increasing the occupied space after folding.

[0026] Combined with Figure 2 and Figure 3 The connecting sleeve 2 is connected with a positioning component that can position the ball joint 12. The positioning component can drive the photovoltaic panel 1 to remain in the same plane. The positioning component includes a limiting groove 6 connected to the end of the ball joint 12 away from the connecting shaft 3. The middle part of the connecting sleeve 2 is connected with a receiving cavity 7. A spring 8 is connected in the receiving cavity 7. The other end of the spring 8 is connected with a limiting block 9. The limiting block 9 cooperates with the limiting groove 6. The connecting sleeve 2 is connected with a sliding hole 10 at the receiving cavity 7;

[0027] The cooperation setting of the positioning assembly in the above structure makes it easy to position the photovoltaic panel 1 in a plane through the positioning assembly. When the ball joint 12 is aligned with the limit block 9 at one end away from the connecting shaft 3, the limit block 9 cooperates with the limit groove 6 under the elastic force of the spring 8. At this time, one end of the limit block 9 is located in the limit groove 6, and the other end is located in the accommodating cavity 7, so that the adjacent photovoltaic panels 1, the limit blocks 9, and the connecting shaft 3 are coplanar to achieve the purpose of positioning, thereby avoiding the angle change of each photovoltaic panel 1 due to external force, thereby affecting the light gain.

[0028] Embodiment 2

[0029] Based on the first embodiment, combined with the attached Figure 2 and Figure 3 A driving rod 11 is connected to the limit block 9 , and the driving rod 11 slides through the sliding hole 10 , and the other end of the driving rod 11 does not exceed the surface of the photovoltaic panel 1 .

[0030] Through the matching arrangement of the sliding hole 10 and the driving rod 11 in the above structure, it is convenient to move the driving rod 11, and the driving rod 11 drives the limit block 9 to move back into the accommodating cavity 7, so that the limit block 9 and the limit groove 6 are no longer matched. At this time, the photovoltaic panel 1 can be rotated again with the ball joint 12 as the axis to achieve folding.

[0031] The specific usage is as follows:

[0032] First, the fan-shaped photovoltaic panels 1 are unfolded respectively so that the adjacent photovoltaic panels 1 form a coplanar surface. At this time, the connecting shaft 3 is on the plane where the photovoltaic panels 1 are located as the photovoltaic panels are unfolded. At this time, the end of the ball joint 12 away from the connecting shaft 3 is opposite to the center of the connecting sleeve 2. The limit block 9 slides from the accommodating cavity 7 to the limit groove 6 under the elastic force of the spring 8, and then the connecting shaft 3 and the photovoltaic panels 1 on both sides are coplanarly positioned to prevent the photovoltaic panels 1 from being deflected at an angle to each other under the action of external forces and affecting the light gain. Only one of the photovoltaic panels needs to be connected to complete the installation;

[0033] Then, when it is necessary to fold and store it, the driving rod 11 can be moved, and the driving rod 11 drives the limit block 9 to move back into the accommodating cavity 7, so that the limit block 9 and the limit groove 6 are no longer matched. At this time, the photovoltaic panel 1 can be rotated again with the ball joint 12 as the axis. After the connecting shaft 3 is rotated 90° through the ball joint 122, when the connecting shaft 3 and the connecting sleeve 2 are perpendicular to each other, the distance between the centers of the ball joint 12 is not less than the thickness of the photovoltaic panel 1, so that the adjacent photovoltaic panels 1 can be parallel to each other after folding, which is convenient for reducing the occupied space and facilitating transportation or storage; the other end of the driving rod 11 does not exceed the surface of the photovoltaic panel 1, so as to avoid interference between the driving rods 11.
