The application discloses a data storage method, device and equipment for a fully-mechanized coal mining face, relates to the technical field of coal mining, and can solve the problem of low data use efficiency of various business systems of the fully-mechanized coal mining face. The method comprises the following steps: acquiring equipment data of the fully-mechanized coal mining face, and converting the equipment data into object model data with unified format; storing the object model data in an original database according to a preset table division strategy; and cleaning up object model data with a storage duration greater than a preset first duration in the original database.

The logistics vehicle comprises a compartment, a cover plate set, a push plate set and an air cylinder, the compartment is installed on the logistics vehicle, a delivery assembly used for delivering the logistics box at a fixed point is arranged behind the compartment, and the delivery assembly comprises a slide moving assembly used for moving a slide and the push plate set used for limiting the logistics box; the push plate set comprises a fixed plate set and a movable plate set, the fixed plate set comprises a fixed plate moving mechanism and a logistics box pushing mechanism, the delivery assembly is connected with the cover plate set, a deformation mechanism used for converting the cover plate set into a slide is arranged in the cover plate set, and the deformation mechanism is connected with the lifting mechanism through bevel gears. The lifting mechanism is arranged in the fixing plate set and used for lifting the fixing plates, and an air cylinder used for adjusting the angle of the slide is hinged below the cover plate set. According to the logistics vehicle, fixed-point delivery can be achieved, the cover plate set is changed into a slide state through the deformation mechanism, so that the logistics boxes are effectively classified, the sorting speed of the logistics boxes is increased, the logistics efficiency is improved, and the labor cost is saved.

The utility model provides a fan structure of a Roman umbrella, and belongs to the technical field of Roman umbrellas. The umbrella stand solves the problem that an existing fan structure can affect storage of an umbrella stand. According to the fan structure of the Roman umbrella, the Roman umbrella comprises an umbrella stand, the umbrella stand comprises a lower umbrella disc and lower umbrella ribs evenly hinged to the lower umbrella disc in the circumferential direction, the lower umbrella disc is connected with an electric fan driving piece, a driving shaft of the electric fan driving piece is fixedly connected with a rotor, the end of one end of the driving shaft is connected with an illuminating lamp holder, and the driving shaft is rotationally connected with a rotating shell through a bearing; a stator matched with the rotor is fixed in the rotating shell, the rotating shell is located between the lighting lamp holder and the lower umbrella disc, a plurality of fan blades are hinged to the outer edge of the rotating shell in the circumferential direction, and when the fan blades are folded between the lower umbrella disc and the lighting lamp holder, the outer edges of the fan blades are located in the outer edge of the lighting lamp holder in the radial direction. When the fan structure of the Roman umbrella is stored, the fan blades are hidden, umbrella folding of the umbrella stand is not affected, and normal storage of the umbrella stand can be guaranteed while the fan blows air.

This utility model relates to the field of precast concrete technology, specifically a lightweight precast concrete component that is easy to lift and assemble. It includes a precast component body, with embedded parts on the sides of the body and hollow columns fixed inside the embedded parts. Pairs of embedded parts are connected to each other via the hollow columns. Each embedded part has an interface, and a splicing component is nested inside the interface. The splicing component and the interface form a detachable connection, connecting adjacent precast components. This lightweight precast concrete component, which is easy to lift and assemble, provides a foundation for subsequent splicing by setting embedded parts within the precast component body. The embedded parts, combined with the hollow columns, also improve the internal crack resistance of the precast component body, reducing its weight. Furthermore, the pre-installed hanging rings inside the precast component body facilitate subsequent lifting, and the hidden hanging rings do not affect the transportation and storage of the precast component body.

The utility model discloses a dough fermentation powder moisture -proof storage jar, including jar body, still including moistureproof mechanism, the jar body inside is provided with moistureproof mechanism, the moistureproof mechanism includes snap ring, hollow screw ring, cross -beam, round table form card cover, connecting rod, fixed link, mounting ring and trepan tray, the jar body top detachable connection has snap ring and snap ring bottom welding has inserted into the hollow screw ring of jar body inside, and the hollow screw ring of snap ring bottom will be connected with the jar body inner wall, and the most bottom round table form card cover is connected between the mounting ring of the most bottom inside jar body, at this time, the bagged food desiccant of trepan tray inside is put into the jar body inside different height position, owing to the restriction of round table form card cover, makes trepan tray not to be covered by powder material, through the trepan tray loading bagged desiccant of being located at different depth, makes it play a role at the different height position inside jar body, does not influence the storage of fermentation powder, can improve dehumidification drying effect simultaneously, avoids metamorphic.
