The utility model discloses a photovoltaic support structure for gobi, belongs to photovoltaic field, including crossbeam and adjusting spare. The hinged support is formed in the crossbeam. The adjusting spare includes the hinge and the rotating lever of mutual fixation, and the hinge is limited in the hinged support, and the both ends of rotating lever respectively penetrate crossbeam. The hinge and the hinged support constitute the rotary connection structure, and the crossbeam is as the core bearing platform of multiple photovoltaic panels arranged along the length of crossbeam, so that photovoltaic panel has the ability of adjusting the inclination angle relative to the transverse. The hinge inlay structure avoids direct exposure, improves the sand and wind resistance performance, prolongs the service life.

The utility model discloses a tunnel escape pipeline emergency rescue protection device which comprises an escape pipe set used for personnel evacuation, a danger avoiding room is arranged at an inlet of the escape pipe set, an escape hole is formed in the rear side of the danger avoiding room, and an inner cavity of the escape hole is communicated with the escape pipe set. A closing assembly used for closing the entrance of the danger-avoiding room so as to prevent dust in the environment from entering the room is arranged at the entrance of the danger-avoiding room, through the arrangement of the danger-avoiding room and the combination of the danger-avoiding room and the escape pipe set, the danger-avoiding room is firstly used for providing a temporary escape space for personnel to prevent the invasion of dust, falling stones and splashes, and after the environment is safe, the danger-avoiding room is used for protecting the personnel. And people can evacuate through the escape pipe group, so that the people are prevented from being directly exposed in a severe environment, and the evacuation safety is guaranteed.

The utility model discloses a data line plug protective sleeve, which comprises a lower box assembly and an upper cover assembly, the lower box assembly comprises a bottom box, an inner column, a limiting plate, a large clamping cover, a large fixing block, a large inserting block, a small clamping cover, a small fixing block, a small inserting block and a clamping hole, and the inner bottom surface of the bottom box is fixedly connected with the inner column, the large clamping cover, the large fixing block, the small clamping cover and the small fixing block. By arranging the lower box assembly and the upper cover assembly, during use, a data line can be wound on an inner column and is wound in the bottom box under the limitation of a limiting plate, and plugs at the two ends of the data line can be inserted into a large insertion block and a small insertion block respectively, so that the plugs are partially filled and are prevented from being directly exposed to be damaged; meanwhile, the large clamping cover and the small clamping cover form protection for the plug part, safety of the data line and the data line plug is improved, then the top cover is covered, storage of the data line is completed, all the data line are concentrated in the formed small closed box, and carrying is convenient.
