[0023] Reference Figure 1-4 , a photovoltaic power station support foundation adhesive structure, including a pile foundation 1, the pile foundation 1 is provided with two groups, the two groups are divided into two sides, each group of pile foundations 1 is provided with two, which are respectively arranged on the left and right sides, and the first support rod 2 and the second support rod 3 are respectively installed on the pile foundations 1 on the left and right sides, and a bottom frame 4 is installed above the first support rod 2 and the second support rod 3, and a photovoltaic panel 5 is installed on the surface of the bottom frame 4, and fixing grooves 6 are opened on both sides of the top of the pile foundation 1, and the bottom ends of the first support rod 2 and the second support rod 3 are fixedly connected to a bottom plate 7, and U-shaped frames 8 are installed on both sides of the bottom end of the bottom plate 7, and the top opening of the U-shaped frame 8 extends to the top of the bottom plate 7, and the two U-shaped frames 8 are respectively inserted into the inner sides of the two fixing grooves 6, and a plurality of tooth-shaped protrusions 9 extending inwardly are arranged on both sides of the U-shaped frame 8, and a plurality of strip holes 10 are opened on the upper inclined surface of the tooth-shaped protrusion 9, and a plurality of through holes 11 are opened on both side walls of the U-shaped frame 8, and structural adhesive is filled between the inner side of the U-shaped frame 8 and the fixing groove 6;

[0024] The technical solution adopted above is that when the bottom end of the bracket is glued to the pile foundation 1, the U-shaped frame 8 at the bottom end of the bottom plate 7 is inserted into the inner side of the corresponding fixing groove 6, and then the structural glue is filled into the U-shaped frame 8 and the fixing groove 6 from the top opening of the U-shaped frame 8. Part of the structural glue will be filled into the inner wall of the fixing groove 6 and the toothed protrusion 9 bracket through the strip hole 10. The toothed protrusion 9 provided can increase the filling area of ​​the structural glue between the fixing groove 6 and the U-shaped frame 8, thereby improving the bonding firmness.

[0025] A triangular plate 14 is installed around the bottom plate 7 and between the second support rod 3, and a plurality of grooves 12 are provided at both ends of the inner wall of the fixing groove 6;

[0026] The technical solution adopted above, through the provision of the groove 12, allows part of the structural adhesive in the fixing groove 6 to enter the groove 12, thereby making it difficult for the structural adhesive in the fixing groove 6 to be pulled out of the fixing groove 6 as a whole, thereby improving the strength of the bonding.

A U-shaped rod 18 is fixedly connected to the bottom of the bottom frame 4, and a movable block 19 is slidably sleeved on the outside of the U-shaped rod 18. The top of the movable rod 17 is hinged to the bottom of the movable block 19.

[0030] In the technical solution adopted above, the bottom frame 4 and the right side of the photovoltaic panel 5 can be adjusted in inclination angle by rotating the hinge point of the columnar rod 15, and the corresponding connection position between the top of the movable rod 17 and the bottom frame 4 will change. At this time, slide the movable block 19 along the direction of the U-shaped rod 18 so that it slides to the top of the movable rod 17, adjust the telescopic length of the movable rod 17, and make its top end hinged with the movable block 19.

When the locking screw 22 continues to be tightened, the inclined surfaces of the extrusion blocks 21 on both sides are squeezed, causing the two extrusion blocks 21 to move outward. The outward side of the extrusion block 21 is provided with anti-slip grooves. When the extrusion block 21 moves outward, it will gradually press against the inner wall of the slide groove 16, thereby achieving the effect of fixing the position of the movable rod 17 through greater friction.

[0033] A hoop 24 is sleeved on the outside of the columnar rod 15, a reinforcing rod 25 is hingedly connected to the outside of the hoop 24, and the top end of the reinforcing rod 25 is hingedly connected to the bottom frame 4;
