The pressing plate assembly comprises a pressing plate body, wherein the pressing plate body is provided with a clamping state and a releasing state, the pressing plate body is suitable for clamping and fixing the photovoltaic module when in the clamping state, and the pressing plate body is suitable for moving relative to the photovoltaic module when in the releasing state; and, a step of, in the first embodiment,

A pre-connection structure connectable to the platen body; and, a step of, in the first embodiment,

The locking piece is connected with the pressing plate body through the pre-connecting structure so as to keep the position fixed relative to the pressing plate body; and, a step of, in the first embodiment,

And the connecting piece is in adjustable threaded connection with the locking piece, so that the pressing plate body is switched between a clamping state and a releasing state.

2. The photovoltaic module securing structure of claim 1, wherein: the pre-connection structure comprises a buckle plate, the buckle plate is detachably connected with the pressing plate body, a mounting hole is formed in the buckle plate and is suitable for the locking piece to be inserted, and the locking piece is limited to rotate relative to the pressing plate body.

3. The photovoltaic module securing structure according to claim 2, wherein: the locking piece comprises a convex part, the convex part protrudes outwards along the radial direction of the locking piece, and when the pressing plate body is in a clamping state, the pinch plate and the pressing plate body respectively abut against two opposite faces of the convex part so as to limit the locking piece to be separated from the mounting hole.

4. A photovoltaic module fixing structure according to claim 2 or 3, wherein: the pinch plate is clamped with the pressing plate body.

5. The photovoltaic module securing structure according to claim 4, wherein: the buckle plate comprises a buckle body, wherein the buckle body is arranged on the inner side of the buckle body, and the buckle body is connected with the end part of the buckle body in a clamping manner.

6. The photovoltaic module securing structure of claim 1, wherein the platen body comprises:

the locking piece is arranged on the upper pressing plate; and, a step of, in the first embodiment,

The lower pressing plate is oppositely arranged with the upper pressing plate to clamp the photovoltaic module, and the connecting piece penetrates through the lower pressing plate to be connected with the locking piece so as to adjust the distance between the upper pressing plate and the lower pressing plate, so that the pressing plate body can be switched between a clamping state and a releasing state.

7. The photovoltaic module securing structure according to claim 6, wherein: the upper pressing plate is in sliding connection with the lower pressing plate along the height direction of the pressing plate body.

8. The photovoltaic module securing structure according to claim 7, wherein: the pressing plate body further comprises an elastic piece, and two ends of the elastic piece respectively abut against the upper pressing plate and the lower pressing plate, so that the upper pressing plate is far away from the lower pressing plate.

9. The photovoltaic module fixing structure according to claim 1 or 6, wherein: the pressing plate assembly comprises a pressing plate body and is characterized by further comprising a fixing piece, wherein the pressing plate assembly is fixed on the fixing piece through the cooperation of the connecting piece and the locking piece, one of the pressing plate body and the fixing piece is provided with an inserting portion, the other one of the pressing plate body and the fixing piece is provided with a groove, and the inserting portion is suitable for being inserted into the groove and abutting against groove walls on two sides of the groove so as to limit the pressing plate body to rotate relative to the fixing piece.

10. A photovoltaic system, characterized by: use of a photovoltaic module securing structure according to any one of claims 1 to 9.
