Claims

1. A photovoltaic pile power head clamp, characterized in that: The device includes an installation cylinder with an inner diameter greater than or equal to the outer diameter of the photovoltaic pile. At least one base is fixedly provided on the outer side wall of the installation cylinder along the circumferential direction. Each base is provided with an inclined hydraulic clamping mechanism. An opening is provided on the outer side wall of the installation cylinder for each hydraulic clamping mechanism. The opening communicates with the inside of the installation cylinder. The hydraulic clamping mechanism clamps and fixes the photovoltaic pile at an inclined downward direction. The clamping end of the hydraulic clamping mechanism is lower than the upper end face of the installation cylinder.

2. The photovoltaic pile drive head clamp of claim 1, wherein: The hydraulic clamping mechanism includes a hydraulic cylinder and a pile clamping plate. The hydraulic cylinder is mounted on the base, and the telescopic end of the hydraulic cylinder is fixedly connected to the pile clamping plate. The hydraulic cylinder is used to drive the pile clamping plate to move closer to or further away from the mounting cylinder.

3. The photovoltaic pile drive head clamp of claim 1, wherein: A protrusion is fixedly provided on one side of the bottom end of the mounting cylinder.

4. The photovoltaic pile drive head clamp of claim 3, wherein: The bottom end of the mounting cylinder is provided with a clearance section on the side away from the protrusion.

5. A photovoltaic pile power head, comprising the photovoltaic pile power head clamp as described in any one of claims 1-4, characterized in that: It also includes a rotary drive and a rotary oil supply connector. The output end of the rotary drive is fixedly provided with an output shaft. The top end of the mounting cylinder is fixedly installed on the output shaft. The rotary oil supply connector includes an inner cylinder and an outer cylinder. The inner cylinder and the outer cylinder are rotatably coupled. One of the inner cylinder and the outer cylinder is fixedly installed on the output shaft and is provided with an oil supply conduit between it and the hydraulic clamping mechanism. The other cylinder can rotate relative to the output shaft.

6. The photovoltaic pile drive head of claim 5, wherein: An annular groove is provided between the outer cylinder and the inner cylinder. A first channel is provided through the inner cylinder, with one end of the first channel communicating with the annular groove. A second channel is provided through the outer cylinder, with one end of the second channel communicating with the annular groove.

7. The photovoltaic pile drive head of claim 5, wherein: A mounting bracket is fixedly provided on the outside of the rotary drive component, and an anti-rotation plate is provided between the inner cylinder and the mounting bracket. One end of the anti-rotation plate is fixedly connected to the inner cylinder, and the other end is fixedly connected to the mounting bracket.

8. A photovoltaic pile drive head according to claim 7, characterized in that: An installation ring is fixedly sleeved on the output shaft, the outer cylinder is fixedly connected to the installation ring, and the top end of the installation cylinder is fixedly connected to the installation ring.

9. The photovoltaic pile drive head of claim 7, wherein: A connecting device is fixedly provided on the top of the mounting bracket.
