Each set of maintenance gates has outward-facing U-shaped latches on both sides. Currently, the maintenance gates are locked by placing channel steel that mates with the U-shaped latches on the top of the orifice pier. However, since the bottom water-stop elevation of the gate is approximately 31.72m after locking, and the bottom edge elevation of the unit's air duct is 31.51m, only about 0.21m of the unit's heat dissipation outlet is exposed. In actual operation, it was found that this setting increases the unit's heat dissipation resistance, reduces the fan's airflow, affects the heat dissipation of the main motor stator coil, and leads to problems such as increased equipment operating noise, increased current, and decreased operating efficiency.

The lower end of the steel wire rope segment is fixed with a shackle that mates with the lifting eye bolt, and the upper end of the steel wire rope segment forms a knot that is sleeved on the lifting beam. A U-shaped grooved wheel is fixed to the top of the lifting beam corresponding to the knot for the knot to be embedded.

[0008] Preferably, the bottom of both ends of the lifting beam is provided with positioning posts that can be driven into the ground.

[0009] Preferably, the lifting beam is a non-circular beam, specifically channel steel, etc.
