Photovoltaic panel door type frame with outward tension

The utility model relates to a photovoltaic panel gate-type frame with outward tension, which comprises two main columns, a roof truss and an inhaul cable steel rope, the roof truss is arranged between the two main columns, a fixed pulley A and two fixed pulleys B are arranged at the bottom of the roof truss, the two fixed pulleys B are arranged on two sides of the fixed pulley A, a fixed pulley C is arranged at the top end of each main column, and the inhaul cable steel rope is arranged on the top end of each main column. A fixed pulley D is arranged on the outer side, the inhaul cable steel rope winds around the fixed pulley A, the fixed pulley B, the fixed pulley C and the fixed pulley D, and the two ends of the inhaul cable steel rope are both connected with balance weights. The safety, applicability and durability of the whole door-type rigid frame system are guaranteed after the photovoltaic panel is newly added, and the external tension cable reinforcing technology of the door-type rigid frame body is
