[0002] In a photovoltaic power generation project, it is necessary to position and install a photovoltaic panel assembly on a photovoltaic panel support. The existing installation and fixation method for a photovoltaic panel assembly is generally as follows: Photovoltaic panel assembly fixing and installation screw holes are opened on an installation support, bolt holes are provided on the aluminum alloy frame of the photovoltaic panel assembly, and fixing bolts are inserted between the aluminum alloy frame of the photovoltaic panel assembly and the support to achieve the installation and fixation of the photovoltaic panel assembly; therefore, installation screw holes corresponding to the holes on the aluminum alloy frame of the photovoltaic panel need to be reserved or drilled on the installation support. Especially when there is an error in the reserved screw holes, repeated correction is required, which severely restricts the on-site installation efficiency. Summary of the Invention

[0003] The utility model provides a hole-free support that can conveniently fix a photovoltaic panel assembly, realizing flexible and convenient connection and fixation between the photovoltaic panel assembly and the fixing frame, and avoiding drilling operations during on-site installation and repeated correction when the reserved holes do not correspond.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A hole-free support that can conveniently fix a photovoltaic panel assembly includes a cuboid-shaped cross beam and a cuboid-shaped longitudinal beam. Cuboid-shaped longitudinal beams are arranged parallel to and at intervals from each other on the cuboid-shaped cross beams arranged parallel to and at intervals from each other. The cuboid-shaped cross beam and the cuboid-shaped longitudinal beam form a grid-shaped frame. Support columns are arranged below the grid-shaped frame, and photovoltaic panel assemblies are arranged on the top end surface of the grid-shaped frame; the structures of the cuboid-shaped cross beam and the cuboid-shaped longitudinal beam are exactly the same; on the top end surface of the cuboid-shaped longitudinal beam, a long strip-shaped inverted T-shaped groove is arranged along the longitudinal direction, and an inverted T-shaped slider pressing plate mechanism is movably arranged in the long strip-shaped inverted T-shaped groove. The inverted T-shaped slider pressing plate mechanism is composed of an inverted T-shaped slider, a pressing bolt, and a long strip pressing plate. A threaded counterbore is arranged on the top end surface of the inverted T-shaped slider. After the tail of the pressing bolt passes through the central through hole in the middle of the long strip pressing plate, it is connected to the threaded counterbore; an inverted T-shaped slider is arranged in the long strip-shaped inverted T-shaped groove on the top end surface of the cuboid-shaped longitudinal beam between two adjacent upper and lower photovoltaic panel assemblies. One end of the long strip pressing plate connected to the inverted T-shaped slider is pressed against the top end surface of one photovoltaic panel assembly, and the other end of the long strip pressing plate is pressed against the top end surface of the other photovoltaic panel assembly; by rotating the large head of the pressing bolt, the inverted T-shaped slider pressing plate mechanism presses two adjacent photovoltaic panel assemblies.

[0006] The two horizontal bumps at the lower end of the inverted T-shaped slider are horizontally telescopic bumps. The horizontal bumps are movably arranged in the horizontal groove at the lower end of the inverted T-shaped slider. A spring is arranged at the bottom end of the horizontal groove. One end of the spring is fixed on the inner wall of the bottom end of the horizontal groove, and the other end of the spring is fixedly connected to the inner vertical surface of the horizontal bump. By pressing the outer vertical surface of the horizontal bump, the horizontal bump can be retracted into the horizontal groove.

[0007] On the lower bottom surface of the cuboid-shaped transverse beam, a long strip-shaped inverted T-shaped groove is arranged along the transverse direction; at the cross intersection of the cuboid-shaped transverse beam and the cuboid-shaped longitudinal beam, a box-shaped connection frame is arranged. The box-shaped connection frame is composed of a square top plate and four columns. The top ends of the columns are fixedly connected to the lower bottom surface at the top corners of the square top plate. The square top plate is arranged on the top surface of the cuboid-shaped longitudinal beam.

A connecting bolt is arranged between the bottom ends of the two columns, and the connecting bolt is arranged on the lower bottom surface of the cuboid-shaped transverse beam.

[0008] The box-shaped connection frame of the hole-free bracket of the present utility model can connect the cuboid-shaped transverse beam and the cuboid-shaped longitudinal beam without punching holes, so that the distances between multiple brackets longitudinally and transversely can be adjusted according to the actual needs of installing photovoltaic panel components, and the assembly is flexible; and by cooperating with the inverted T-shaped slider pressing plate mechanism, the photovoltaic panel can be pressed and fixed without punching holes, and the operation is convenient; the setting of the horizontal bumps on both sides of the bottom end of the inverted T-shaped slider of the present utility model can, after placing the photovoltaic panel, first press the horizontal bumps into the horizontal groove, and then directly press the inverted T-shaped slider into the inverted T-shaped groove, which facilitates the connection between the photovoltaic panel quick-fixing component and the transverse rod of the bracket, does not need to slide in from one side of the T-shaped groove, and improves the installation efficiency.

[0012] The present utility model will be described in detail below with reference to the drawings:

[0013] A bracket without hole opening for conveniently fixing a photovoltaic panel assembly, comprising a cuboid-shaped transverse beam 1 and a cuboid-shaped longitudinal beam 2. The cuboid-shaped longitudinal beams 2 are arranged parallel to and spaced apart from each other on the cuboid-shaped transverse beam 1 which are arranged parallel to and spaced apart from each other. The cuboid-shaped transverse beam 1 and the cuboid-shaped longitudinal beam 2 form a grid-shaped frame. A support column is arranged below the grid-shaped frame, and a photovoltaic panel assembly is arranged on the top end surface of the grid-shaped frame; the structures of the cuboid-shaped transverse beam 1 and the cuboid-shaped longitudinal beam 2 are exactly the same. The cuboid-shaped transverse beam 1 and the cuboid-shaped longitudinal beam 2 are abutted against each other back to back. The long strip-shaped inverted T-shaped groove 5 on the cuboid-shaped longitudinal beam 2 faces upward, while the long strip-shaped inverted T-shaped groove of the cuboid-shaped transverse beam 1 faces downward; on the top end surface of the cuboid-shaped longitudinal beam 2, a long strip-shaped inverted T-shaped groove 5 is arranged along the longitudinal direction. An inverted T-shaped slider pressing plate mechanism 4 is movably arranged in the long strip-shaped inverted T-shaped groove 5. The inverted T-shaped slider pressing plate mechanism 4 is composed of an inverted T-shaped slider 41, a pressing bolt 45 and a long strip pressing plate 44. A threaded counterbore 42 is arranged on the top end surface of the inverted T-shaped slider 41. The tail of the pressing bolt 45 first passes through the central through hole in the middle of the long strip pressing plate 44 and then is connected in the threaded counterbore 42; an inverted T-shaped slider 41 is arranged in the long strip-shaped inverted T-shaped groove 5 on the top end surface of the cuboid-shaped longitudinal beam 2 between two adjacent photovoltaic panel assemblies up and down. One end of the long strip pressing plate 44 connected to the inverted T-shaped slider 41 is pressed against the top end surface of one photovoltaic panel assembly, and the other end of the long strip pressing plate 44 is pressed against the top end surface of another photovoltaic panel assembly; by rotating the head 46 of the pressing bolt 45, the inverted T-shaped slider pressing plate mechanism 4 presses the two adjacent photovoltaic panel assemblies; when rotating the head 46 of the pressing bolt 45, the rotating pressing bolt 45 drives the inverted T-shaped slider 41 to move upward. At the same time, the head 46 presses the long strip pressing plate 44 to make the long strip pressing plate 44 move downward. With the upward movement of the inverted T-shaped slider 41, the two horizontal convex blocks 43 also move upward, so that the top end surface of the horizontal convex block 43 is closely abutted against the inner top end surfaces of both sides of the long strip-shaped inverted T-shaped groove 5, thereby realizing the clamping of the photovoltaic panel by the long strip pressing plate 44 and the inverted T-shaped slider 41.

[0014] The two horizontal bumps 43 at the lower end of the inverted T-shaped slider 41 are horizontally telescopic bumps. The horizontal bumps 43 are movably arranged in the horizontal grooves at the lower end of the inverted T-shaped slider 41. A spring is arranged at the bottom end of the horizontal groove. One end of the spring is fixed on the inner wall of the bottom end of the horizontal groove, and the other end of the spring is fixedly connected to the inner vertical surface of the horizontal bump 43. By pressing the outer vertical surface of the horizontal bump 43, the horizontal bump 43 can be retracted into the horizontal groove, so that the inverted T-shaped slider 41 can enter the long strip-shaped inverted T-shaped groove 5 through the top narrow groove of the long strip-shaped inverted T-shaped groove 5. When the two horizontal bumps 43 on the inverted T-shaped slider 41 descend to the bottom of the long strip-shaped inverted T-shaped groove 5, under the action of the spring, the two horizontal bumps 43 extend out to realize the clamping of the inverted T-shaped slider 41 in the long strip-shaped inverted T-shaped groove 5.

The top ends of the columns 32 are fixedly connected to the lower bottom surface at the top corners of the square top plate 31. The square top plate 31 is arranged on the top surface of the cuboid-shaped longitudinal beam 2. The columns 32 are arranged on the right-angle vertical surfaces at the cross intersection of the cuboid-shaped transverse beam 1 and the cuboid-shaped longitudinal beam 2. A connection bolt 33 is arranged between the bottom ends of the two columns 32. The connection bolt 33 is arranged on the lower bottom surface of the cuboid-shaped transverse beam 1.
