[0039] Core Organization Implementation Methods

[0040] 1. Chain drive assembly (claim 1)

[0041] Power transmission path:

[0042] Second motor (23) → Drive wheel (22) → Sprocket (21) → Chain (19) → Lifting platform (8)

[0043] Detailed assembly:

[0044] The second motor (23) is a servo motor (power 1.5kW), which is fixed to the inner wall of the chain box (2) by bolts.

[0045] The drive wheel (22) and the sprocket (21) are engaged by helical gears with a reduction ratio of 5:1.

[0046] The chain (19) is a double-row roller chain, and the end is connected to a high-strength bolt block (17) (material 40Cr alloy steel).

[0047] The side wall of the lifting platform (8) is provided with a connecting groove (18) (with a self-locking buckle) which is rigidly engaged with the connecting block (17).

[0048] Through-hole linkage: A second rectangular through hole is opened on the side wall of the chain box (2), which is coaxially aligned with the first rectangular through hole (4) of the frame, and the chain (19) extends to the lifting platform through this hole.

[0049] 2. Cover plate assembly (claim 2)

[0050] Opening and closing mechanism:

[0051] The cover frame (9) is fixed to the lifting platform (8) by four stainless steel support columns (0.5m high).

[0052] The first motor (12) (stepper motor, torque 20 N·m) is embedded in the motor housing (10), and the output shaft is directly connected to the cover plate (24) shaft.

[0053] The cover plate (24) is a lightweight carbon fiber plate (1.5×0.8m in size) and is hinged on both sides by bearings of the fixing block (11).

[0054] Energy replenishment (claim 3):

[0055] A photovoltaic panel (25) (monocrystalline silicon, efficiency 22%) is embedded on the outer surface of the cover plate (24), and the wires are led to the power supply body (5) through the inner cavity of the hinge shaft to realize solar charging.

[0056] 3. Iron mesh protective assembly (claim 4)

[0057] Structural layout:

[0058] Two pairs of iron mesh baffles (15) (0.6m high) are vertically welded to the edge of the lifting platform (8).
