The invention relates to a movable type deluge sand adding device and a sand-adding modeling method. The sand adding device comprises a sand storage box, a drive travelling mechanism arranged on the top part of the sand storage box, a drawing flashboard arranged on the bottom part of the sand storage box, and an air cylinder for driving the drawing flashboard to move in a reciprocating way. A plurality of sand leakage holes are distributed in a base plate of the sand storage box; the drawing flashboard is arranged on the bottom face of the base plate of the sand storage box; and sand passing holes corresponding to the sand leakage holes on the base plate are distributed in the flashboard. According to the movable type deluge sand adding device and the sand-adding modeling method provided by the invention, the number of working stations in a traditional modeling process is reduced, the number of sand storage hoppers and swing tables is reduced, the equipment structure of a modeling production line is simplified, and the equipment cost is greatly reduced. The sand adding device provided by the invention can move between a modeling station and a laminating station in a reciprocating way and works alternatively, so that not only is a limited space on the production line fully utilized, but also the production efficiency is greatly improved.

The micro-displacement amplifying mechanism provided by the present invention includes: a piezoelectric ceramic driver, a displacement input end, a displacement output end and a multi-level lever. The vertical axis where the piezoelectric ceramic driver is located is symmetrically arranged with respect to the axis of symmetry. Each level of the multi-level lever has 1-2 input ends and at least one output end, and each input end of each level of lever is connected to a certain front-end. One output end or displacement input end of the first-stage lever, and the output end of the last-stage lever is connected to the displacement output end. The micro-displacement amplifying mechanism provided by the present invention, because the multi-stage lever adopts a series-parallel hybrid connection scheme, which is different from the traditional one. The multi-level levers are simply stacked in series, so compared with the prior art, they can achieve a larger magnification in a smaller space, and the structure is arranged in a reasonable and orderly manner, the structure is compact, the limited space is fully utilized, and the flexible hinges are evenly distributed , which is convenient for machining.

The invention relates to a connector of a power adapter. The connector comprises a body, wherein a first side of the body is provided with a first USB (Universal Serial Bus) interface; the body is correspondingly provided with a second USB interface and a power interface; the first USB interface and the second USB interface are electrically connected; and the second USB interface and the power interface can be simultaneously plugged into a USB interface and a power input end of a computer. In the connector of the power adapter, the USB interface is combined on the power interface, thereby the limited space of a notebook computer is sufficiently utilized, and the problem of insufficient USB interfaces of the notebook computer is solved.

The present invention proposes an integrated device for LNG vaporization, venting, recovery, utilization and air supply and pressurization, comprising: a heat exchanger (20), a one-way valve (12), a solenoid valve (13), an HC sensor (14), a dual-purpose Air tank (15), pressure sensor (16), vent valve (17), low pressure filter (18), voltage regulator (19), low pressure solenoid valve (21), electronically controlled pressure regulator (22), The one-way valve (26) and the electromagnetic valve (31), the invention solves the problem of boosting delay of the exhaust gas turbocharger and avoids the surge of the compressor. Make full use of the energy of the turbocharger of the engine, add an air booster device on this basis, and significantly improve the hysteresis of the supercharger, thereby significantly improving the power of the vehicle.

A hydrogen storage container of metal hydride is characterized in that reticular metal pipes are arranged in the hydrogen storage container to be used as hydrogen fluid guide pipes. Compared with the prior art, the hydrogen storage container has the outstanding advantages that 1), a structure of the reticular metal fluid guide pipes is employed, as the screen mesh structure is capable of providing a plurality of passages for hydrogen flowing and heat transfer, blocking is not easy to happen, thereby guaranteeing smooth gas flow, perfect heat transfer property and rapid hydrogen absorption performance of the hydrogen storage container, 2) the reticular metal fluid guide pipes are elastic, when hydrogen storage alloy absorbs hydrogen to expand and the alloy can shrink, therefore the structure can be employed to diminishes a reserved gag of the hydrogen storage container, the limited space of the hydrogen storage container can be sufficiently used, thereby increasing the load of the hydrogen storage alloy and increasing the volume ratio capacity of the hydrogen storage container, simultaneously the structure is light in weight, thereby the weight ratio capacity of the hydrogen storage container can be increased, and 3) the hydrogen storage container is simple in structure, convenient in installation, low in cost, perfect in performance, and stable, safe and reliable in long-term operation.
