The utility model relates to the field of agricultural planting, in particular to an intelligent agricultural greenhouse. According to the intelligent agricultural greenhouse, photosynthesis can be carried out on crops in rainy days, meanwhile, the rolling shed is rotated to shield the ventilation net for shielding rain, ventilation is carried out through the ventilation net in sunny days, the crops are prevented from decaying, the survival rate of the crops is increased, and the ventilation effect is improved. An intelligent agricultural greenhouse comprises a connecting frame, supporting frames and the like, the number of the supporting frames is two, and the connecting frame is connected between the supporting frames. The ventilation net is used for ventilation, when it rains, the rolling shed is put down to shield the ventilation net, and meanwhile the LED plant growth lamp and the carbon dioxide generator are used in cooperation for photosynthesis; therefore, photosynthesis can be carried out on crops in rainy days, meanwhile, the rolling shed is rotated to shield the breathable net for shielding rain, ventilation is carried out through the breathable net in sunny days, the crops are prevented from rotting, and the survival rate and ventilation effect of the crops are improved.

The utility model discloses a multi -functional scaffold, including scaffold frame, the top of scaffold frame is fixed with standing board, and the top fixedly connected with two mounting columns of standing board is installed with the winding drum through the embedded joint bearing rotation between two mounting columns top, and the outer wall of winding drum is around the sunshade cloth. The utility model discloses through the effect of the meshing of first bevel gear and fourth bevel gear drives winding drum rotation to realize the unwinding of sunshade cloth, and simultaneously, the meshing of third bevel gear and second bevel gear drives screw rod rotation to make the connecting rod move outward along the slide rod, and then make first rotary rod and second rotary rod rotate to linear placement to spread out sunshade cloth and shade, and then effectively block the direct sunlight to avoid the high temperature heat stroke of construction personnel easily, sunburn, the application increases the sunshade function on the scaffold to reflect the multi -functional property of scaffold.

The utility model discloses a walking frame of lifting prestressed tensioning jack belongs to building construction auxiliary device technical field, it includes pedestal, is provided with several pairs of gyro wheel at the lower bottom of pedestal, installs the facade support at the upper top end surface of pedestal, is provided with the horizontal top frame at the top of vertical support, installs the horizontal guide rail on the top frame, the horizontal guide rail is set along the length direction of top frame, is movably installed with vertical guide rail on the horizontal guide rail, still is provided with the support board for being cantilevered on the facade support, still is provided with the connecting ladder stand between the extension end of support board and pedestal, the utility model effectively solved the problem that the current practical overhead travelling crane or gantry crane etc.
