The invention discloses an anti-overturning water lifesaving equipment. It solves the problem that the current life-saving equipment at sea does not have the ability to prevent overturning, and cannot meet the life-saving requirements in severe weather such as big waves. It has the advantages of simple structure, convenient use, small size, and effective rescue of people in distress. Its structure is as follows: it has a rescue cabin, and it also includes at least one stable cabin movable with it. The bottom of the stable cabin is provided with a counterweight for stabilization, the top is provided with a hatch, and the inside of the stable cabin is provided with multiple functional cabins. There is a drainage pipe running through the stable cabin up and down in the cabin, the top of the drainage pipe is connected with the ventilation pipe, and the upper end of the ventilation pipe is provided with a first fixed plate to connect with the rescue cabin; there is a second fixed plate on the outer periphery of the stable cabin, and each second fixed plate It is connected with the rescue cabin, and the inner wall of the rescue cabin is provided with a plurality of inflatable airbags.

The invention discloses a supporting system for a concrete precast component and belongs to the technical field of construction tools. The supporting system comprises a first group supporting device, a second group supporting device, a first connecting rod and a second connecting rod, wherein two inclined supporting rods are positioned on the inner side of a first vertical plate respectively; the lower end of one inclined supporting rod is hinged to the ground and the upper end of the inclined supporting rod is hinged to the part, close to the top, of the first vertical plate; the lower end of the other inclined supporting rod is hinged to the ground and the upper end of the inclined supporting rod is hinged to the part, close to the top, of the first vertical plate; the second group supporting device and the first group supporting device are symmetrically arranged; the first connecting rod and the second connecting rod are parallel to each other and are horizontally arranged; a gap is reserved between the first connecting rod and the second connecting rod; one ends of the first connecting rod and the second connecting rod are fixed at the part, close to the top, of the first vertical plate respectively; the other ends of the first connecting rod and the second connecting rod are fixed at the part, close to the top, of the second vertical plate respectively; tie hitch bolts and nuts are arranged inside the gap. According to the invention, the concrete precast component can be mounted more accurately, rapidly and conveniently, and the mounting process is safer.

The invention relates to a device for bearing transparent conductive film glass during thinning single surface and a thinning method for the transparent conductive film glass. The device comprises a sealed vacuum chuck 1 totally covering the conductive film surface of plane glass 4 and adsorbing the plane glass 4; an enclosed air suction duct 1c and a vacuum buffer cavity 1f communicated with theair suction duct are arranged in the vacuum chuck 1; and through an enclosed cavity formed by the air suction duct 1c and the vacuum buffer cavity 1f, the plane glass 4 is always adsorbed in the whole thinning etching flow by maintaining the vacuum degree between the vacuum chuck 1 and the plane glass 4 under the condition of cutting off an external vacuum pump source. In the process of thinning the plane glass borne by the device, one surface of the plane glass is not provided with any shield so as to facilitate thinning treatment, and the enclosed surface of the plane glass can ensure the transparent conductive film is protected from the corrosion of chemical solution, so that the process of thinning the single surface of the transparent conductive film glass is greatly simplified and the cost is reduced.

The invention relates to a transport vehicle for logistics storage, in particular to a convenient using type transport vehicle for the logistics storage. The convenient using type transport vehicle for the logistics storage is capable of meeting the use requirements of workers, the labor intensity is low, and time-saving and labor-saving are achieved; according to the technical scheme, the convenient using type transport vehicle for the logistics storage comprises a base, universal wheels, rolling wheels, a first large guide rod, a second large guide rod, a top plate, a first bearing, a largescrew rod, a large rotating wheel, a second bearing, a large nut and the like, wherein the universal wheels and the rolling wheels are located below the base correspondingly, and the universal wheelsand the rolling wheels are connected with the bottom of the base correspondingly. The convenient using type transport vehicle for the logistics storage is provided, so that a worker can conveniently carry out loading, unloading and transportation on the stacked goods, the use requirements of workers are met, the time and labor are saved, and the labor intensity is low, performance is safe and reliable, the structure is simple, the operation is convenient, and production and manufacture are easy.
