Description

Technical Field

[0001] The present technical solution relates to the technical field of photovoltaic brackets, and in particular to a bidirectional universal adjustment device for a photovoltaic bracket. Background Art

[0002] Photovoltaic brackets are brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. Universal connectors are used during installation to assist in adjustment to adapt to different terrain slopes.

[0003] For example, Chinese patent CN210068723U discloses a universal connector for a photovoltaic bracket, including a first connecting shaft, a connecting through hole, a first connecting member, a second connecting member, a connecting convex strip, a second connecting shaft, a first universal bearing, a second universal bearing and a third universal bearing. The second universal bearing is designed inside the first connecting shaft, and the first steering shaft and the second steering shaft are connected to the first connecting member and the second connecting member. A connecting through hole is provided at the bottom of the first connecting shaft, and the diameter of the connecting through hole is six centimeters, and a circle of threads is provided inside, see Figure 2 The existing photovoltaic support is installed with a mounting column 100 and a transmission connecting rod 200. A reducer 300 is installed on the mounting column 100. The reducer 300 has a shaft 400. The universal adjustment device can be connected between the transmission connecting rod 200 and the shaft 400.

[0004] The above-mentioned photovoltaic bracket uses a universal connector. Due to the inconsistent slope of the on-site terrain, the front and rear rows of installation columns are not in the same straight line, and are not even within the preset installation range. The existing universal connector articulation method mainly uses a through-hole structure for docking. This connection method lacks versatility and flexibility during actual installation and use, and cannot meet other installation requirements, resulting in poor applicability and needs to be improved. Summary of the invention

[0005] In order to improve the problem of poor applicability of universal connectors in connection and use, the present technical solution provides a bidirectional universal adjustment device for a photovoltaic bracket.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A bidirectional universal adjustment device for a photovoltaic bracket comprises a universal rotating block and two shaft connecting members arranged on the universal rotating block, wherein the two shaft connecting members are located on opposite sides of the universal rotating block, and the two shaft connecting members are both hinged to the universal rotating block, and the hinge axes of the two shaft connecting members are perpendicular to each other, and the two shaft connecting members both have connecting grooves, and the two connecting grooves are arranged one by one on the end surface of the shaft connecting member facing away from the universal rotating block, and the penetration directions of the two connecting grooves are arranged perpendicular to each other, and the shaft connecting members are both provided with connecting holes, and the connecting holes penetrate the opposite side walls of the connecting grooves one by one.

[0008] Through the above technical scheme, the transmission connecting rod and the shaft rod are respectively embedded in the connecting grooves of the two shaft connecting parts in a one-to-one correspondence, and the connecting parts pass through the connecting holes and the corresponding parts, so that there is a hinged relationship between the two parts and the two shaft connecting parts. Based on the fact that the through directions of the two connecting grooves are perpendicular to each other, the two parts can rotate relative to each other along the connecting grooves in two orthogonal directions horizontally or vertically to adjust the angle. When the slope of the installation terrain is inconsistent, the corresponding installation angle is adjusted, thereby enhancing the connection and coordination ability between the transmission connecting rod and the shaft rod and improving applicability.

[0009] The two shaft connections are hinged on opposite sides of the universal joint block. Based on the fact that the hinge axes of the two shaft connections are perpendicular to each other, the two components rotate along the hinge axis with the universal joint block following the shaft connections. The adjustable range is further expanded through the hinge connection between the shaft connection and the corresponding components, and the hinge connection between the shaft connection and the universal joint block, thereby improving the connection flexibility and further improving the adjustment adaptability.

[0010] Preferably, two opposite side walls of the connecting groove are thin-walled and have elastic parts formed thereon.

[0011] Through the above technical solution, the thin-wall design of the elastic part enables the elastic part to deform under pressure. When the size of the component to be connected is less than or equal to the width of the connecting groove, the elastic parts on both sides can be deformed to approach the opposite sides of the component to be connected in the connecting groove, thereby reducing the excess space between the component and the elastic parts on both sides after the component is hinged, limiting the swinging deviation of the component along the hinge axis, and being suitable for components to be connected of different sizes, thereby improving applicability and connection stability.

[0012] Preferably, the elastic portion protrudes toward the connecting groove to form a contact surface, the connecting hole is located on the contact surface, and the contact surfaces on both sides are close to each other to form surface contact.

[0013] Through the above technical solution, when the elastic parts on both sides are deformed and pressed against the opposite sides of the parts to be connected, based on the fact that the contact surface protrudes from the end surface of the elastic part facing the connecting groove, the contact surfaces on both sides first contact the parts to be connected, thereby reducing the deformation of the elastic part, ensuring that the deformation range of the elastic part is within a reasonable range, avoiding damage or failure caused by excessive deformation for a long time, improving durability, forming a stable surface contact between the contact surface and the parts to be connected, providing a more uniform and stable clamping effect, and further improving the connection stability.

[0014] Preferably, the abutment surfaces on both sides guide the connection groove to expand outward.

[0015] Through the above technical solution, based on the fact that the contact surface is an arc surface, the arc guide connecting groove on one side of the contact surface close to the groove is flared in the direction away from the highest point of the contact surface. The parts to be connected are guided through the flared part and embedded in the connecting groove, thereby improving the smoothness and convenience of the fitting.

[0016] Preferably, the shaft connecting member has a connecting extension part, two of which are provided, and the two connecting extension parts are located one-to-one on opposite sides of the universal rotating block, and the connecting extension part is provided with a hinge pin, and the shaft connecting member is hinged to the universal rotating block through the hinge pin.

[0017] Through the above technical solution, the shaft connecting member has two connecting extensions, and the space between the two connecting extensions is adapted to the universal joint block, so that the two connecting extensions are located one-to-one on the opposite sides of the universal joint block, and two hinge pins are inserted through the connecting extensions on both sides one-to-one and then embedded in the opposite end faces of the universal joint block, thereby realizing the hinge connection between the shaft connecting member and the universal joint block.

[0018] Preferably, a clearance space is reserved between the shaft connection member and the universal rotating block, and the clearance space is used to provide rotation clearance.

[0019] Through the above technical solution, the clearance space provides rotation clearance for the axial rotating part. When the axial rotating part rotates 60° relative to the universal rotating block, the axial rotating part will interfere with the connecting extension part of another axial rotating part, thereby achieving a maximum bidirectional rotation angle of 60° for a single axial rotating part along the hinge axis.

[0020] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0021] 1. This technical solution embeds two components to be connected into the connection grooves of the two shaft connection parts one by one, and the penetration directions of the two fixing grooves are perpendicular to each other. The two components can be relatively rotated along the connection grooves in two orthogonal directions, respectively, and the corresponding installation angle can be adjusted when the slope of the installation terrain is inconsistent, thereby enhancing the connection and matching ability between the transmission connecting rod and the shaft rod and improving the applicability;

[0022] 2. This technical solution hinges two shaft connections on opposite sides of the universal joint block. The hinge axes of the two shaft connections are perpendicular to each other. The two components rotate along the hinge axis with the universal joint block following the shaft connections, thereby improving the connection flexibility between the transmission connecting rod and the shaft rod and making the adjustment adaptable.

DETAILED DESCRIPTION

[0029] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] See also Figure 1 and Figure 5 A photovoltaic bracket bidirectional universal adjustment device includes a universal rotating block 1 and two shaft connecting members 2. The universal rotating block 1 is in the shape of a cube. The two shaft connecting members 2 are located on opposite sides of the universal rotating block 1 in a one-to-one correspondence. Each shaft connecting member 2 is provided with a connecting groove 3. The two connecting grooves 3 are correspondingly arranged on the end faces of the two shaft connecting members 2 on one side away from the universal rotating block 1. The penetration directions between the two connecting grooves 3 are arranged perpendicular to each other. The two shaft connecting members 2 are respectively hinged to the shaft rod 400 and the transmission connecting rod 200 in a one-to-one correspondence. The specific articulation method is that each shaft connecting member 2 is provided with two connecting holes 4, and the two connecting holes 4 are correspondingly passed through the connecting grooves 3. On the opposite side wall, the shaft rod 400 is embedded in one of the connecting grooves 3, and the embedded end of the shaft rod 400 is penetrated by a through hole 1, and the through hole 1 is arranged in correspondence with the connecting hole 4 in the connecting groove 3. The transmission connecting rod 200 is embedded in the other connecting groove 3, and the embedded end of the transmission connecting rod 200 is penetrated by a through hole 2, and the through hole 2 is arranged in correspondence with the connecting hole 4 in the connecting groove 3. The hinge axis is provided by the connecting member passing through the through hole and the connecting hole 4, so as to realize the hinge connection of the two shaft connecting members 2 with the shaft rod 400 and the transmission connecting rod 200 respectively. In this embodiment, the rotation of the shaft rod 400 and the transmission connecting rod 200 relative to the hinge axis satisfies the adjustment angle of at least 15° in both directions.

[0032] See also Figure 2 and Figure 3, the two shaft connecting members 2 are both hinged to the universal rotating block 1, and the hinge axes of the two shaft connecting members 2 are perpendicular to each other. The specific hinge method can usually be adopted that each shaft connecting member 2 is provided with a connecting extension part 7, and there are two connecting extension parts 7. The two connecting extension parts 7 are both located on the side of the shaft connecting part close to the universal rotating block 1, and the two connecting extension parts 7 are located on the opposite sides of the universal rotating block 1 in a one-to-one correspondence. The opposite end surfaces of the connecting extension parts 7 on both sides of the universal rotating block 1 corresponding to the connecting extension parts 7 are provided with through holes three, and the connecting extension parts 7 are provided with matching through holes four corresponding to the through holes three. The through holes four are arranged in a corresponding manner to the through holes three so that the through holes four are aligned with the through-holes three. The connecting extension parts 7 on each side are provided with hinge pins 8, which pass through the through holes four and then are embedded in the through holes three. The hinge pins 8 are fixed to the universal rotating block 1 to provide a hinge axis, thereby realizing the hinge connection between the shaft connecting member 2 and the universal rotating block 1.

[0033] A clearance space 9 is left between the shaft connection member 2 and the universal rotating block 1 to prevent the shaft connection member 2 from interfering with the universal rotating block 1. The clearance space 9 is used to provide rotation clearance. When one of the shaft connection members 2 rotates, the shaft connection member 2 will interfere with the shaft connection member 2 on the other side, thereby limiting the rotation. This embodiment shows that a single shaft connection member 2 can rotate at least 60° in both directions relative to the universal rotating block 1.

[0034] Elastic parts 5 are formed on the opposite side walls of each connecting groove 3. The elastic parts 5 on both sides are thin-walled, so that the elastic parts 5 have the ability of elastic deformation. The two elastic parts 5 are bent and formed by the shaft connecting member 2, so that the two elastic parts 5 are integrally formed. Two groups of elastic parts 5 are correspondingly formed on the two shaft connecting members 2, and the distribution direction of one group of elastic parts 5 is perpendicular to the distribution direction of the other group of elastic parts 5, thereby realizing that the through directions of the two connecting grooves 3 are mutually perpendicular.

[0035] Each elastic part 5 has a contact surface 6, which is formed by bending the elastic part 5 toward the inside of the connecting groove 3, so that the contact surface 6 protrudes toward the inside of the connecting groove 3, and the slope surfaces of the contact surfaces 6 on both sides away from the bottom of the connecting groove 3 cooperate with each other, so that the contact surfaces 6 on both sides are inclined to guide the fixed groove opening outward through the slope surface, and the expansion range is the distance from the highest point of the contact surface 6 to the fixed groove opening. After the transmission connecting rod 200 and the shaft rod 400 are hinged to the two shaft connecting parts, when the connecting parts are tightened, the elastic parts on both sides are deformed and approach each other, so that the contact surfaces 6 on both sides first press against the opposite side walls of the transmission connecting rod 200 or the shaft rod 400 to form surface contact.

[0036] The specific working process of this program is as follows:

[0037] The technical solution is to embed the transmission connecting rod 200 and the shaft rod 400 into the connecting grooves 3 of the two shaft connecting members 2 in a one-to-one correspondence, and realize hinge connection with the corresponding parts by the connecting members passing through the connecting holes 4. Based on the fact that the through directions of the two connecting grooves 3 are perpendicular to each other, the transmission connecting rod 200 and the shaft rod 400 can rotate relative to each other along the connecting grooves 3 in two orthogonal directions of the horizontal or vertical direction to adjust the angle, and the two shaft connecting members 2 are hinged to the opposite sides of the universal rotating block 1. The hinge axes of the two shaft connecting parts are perpendicular to each other, which further expands the adjustment range of the connection between the transmission connecting rod 200 and the shaft rod 400, is suitable for more installation terrain slope differences, and improves applicability.
