A pre-embedded steel sleeve for a photovoltaic pile with drainage function according to claim 3, characterized in that: The pre-embedded steel sleeve also includes a heating wire (12) installed inside the hollow ring (4) to heat the air inside the hollow ring (4). The heating wire (12) is electrically connected to the humidity sensor (9) through the control module.

5. A method for using the pre-embedded steel sleeve of a photovoltaic pile with drainage function as described in claim 4, characterized in that, Includes the following steps: S1. First, insert the device into the soil, then push the sliding rod (101) downward. The sliding rod (101) drives the waist-shaped perforated plate (103) to move to the left through the contact rod (102). The waist-shaped perforated plate (103) drives the L-shaped baffle (105) to move to the left. The L-shaped baffle (105) stops blocking the outlet of the drainage frame (10). Then, put the photovoltaic pile into the ceramic sleeve (2). S2. When the humidity sensor (9) detects that the humidity inside the ceramic sleeve (2) has reached its maximum value, the humidity sensor (9) controls the air pump (92) to start through the control module. The air pump (92) discharges air into the air supply pipe (91) through the hose (93). The air supply pipe (91) discharges air into the nozzle (5) through the hollow ring (4). The nozzle (5) discharges air into the ceramic sleeve (2). The spiral plate (6) guides the air, so that the air forms a cyclone. The air forming the cyclone blows the water in the ceramic sleeve (2) downward. The blown water flows to the liquid collection frame (8), and then enters the drain frame (10) through the guide frame (104) and is discharged to the outside of the ceramic sleeve (2). S3. When the humidity inside the ceramic sleeve (2) drops to the standard value, the humidity sensor (9) controls the air pump (92) to shut down through the control module, the air stops being discharged into the hose (93), and the nozzle (5) stops spraying air.
