A rib-shaped guiderail panel comprising a beam panel (100) and a rib panel (200). The rib panel (200) is arranged on a panel face of the beam panel (100) and is arranged integrally with the beam panel (100). The beam panel (100) and the rib panel (200) extend along the lengthwise direction of the guiderail panel. The beam panel (100) is a thermoplastic composite panel or a thermoplastic material panel. The rib panel (200) is a thermoplastic composite panel. The thermoplastic composite panel comprises a reinforced skeleton (4), while the reinforced skeleton (4) is covered thereout with a thermoplastic material layer. The rib-shaped guiderail panel is corrosion-resistant, has a simplified manufacturing process, and ensures vehicle and personnel safety by adsorbing impact energies.

The invention discloses a spiral spring type socket, and belongs to the field of electric connectors. A specific technical scheme is as follows: the spiral spring type socket comprises an insulating outer sleeve, an inner sleeve and a plurality of wire springs; the inner sleeve is of a vertically-through cylindrical structure; a plurality of groups of through holes are formed in the side wall of the inner sleeve from top to bottom; each group comprises two layers of through holes which are formed in a staggered manner; each layer of through holes are uniformly distributed on the same horizontal plane; each wire spring sequentially penetrates through the same group of through holes along the circumferential direction of the inner sleeve and is connected end to end to form a wire spring wirering; the inner sleeve provided with the wire spring wire ring is arranged inside the insulating outer sleeve, the inner sleeve is fixedly connected with the insulating outer sleeve, and the inner sleeve and the plurality of wire springs are made of conductive materials. The multi-layer wire spring wire spiral layout is adopted, so that the plug force change of a jack in the operation process ismore stable, an impact peak value is reduced, and the wear degree of a contact pin and the jack is reduced.

The invention discloses a large overload impact resistant storage device and a preparation method thereof. The storage device comprises a storage board, an inner casing, a first potting glue, a second potting glue, an outer casing, an inner cover plate and an outer cover plate, the inner shell is a hollow shell, which forms a first hollow cavity after being sealed by the inner cover plate, the storage plate is accommodated in the first hollow cavity, and the first filling The encapsulant is disposed in the first hollow cavity and fills the remaining space of the first hollow cavity, so as to wrap the storage board tightly; the outer shell is a hollow shell, which passes through the outer cover After the plate is covered, a second hollow cavity is formed. The inner casing and the inner cover plate covering the storage plate are integrally accommodated in the second hollow cavity, and the second potting compound is filled and arranged in the second hollow cavity. The hollow cavity is filled with the remaining space of the second hollow cavity, so as to wrap the inner casing and the inner cover tightly, thereby greatly improving the impact resistance of the storage device, and realizing the impact resistance in the high overload impact environment Medium storage devices can still guarantee the reliability of stored data.

A hollow guiderail panel comprising a beam panel (100) and first rib panels (200). The multiple first rib panels (200) are arranged on a panel face of the beam panel (100) and are integrally arranged with the beam panel (100). The beam panel (100) and the first rib panels (200) extend along the lengthwise direction of the guiderail panel. Every two adjacent first rib panels (200) are provided therebetween with a second rib panel (300). The second rib panel (300) extends along the lengthwise direction of the guiderail panel and encloses a hollow cavity in conjunction with the first rib panels (200) and the beam panel (100). The beam panel (100) and the second rib panel (300) are thermoplastic composite panels or thermoplastic material panels. The first rib panels (200) are thermoplastic composite panels. Each thermoplastic composite panel comprises a reinforced skeleton (4). The reinforced skeleton (4) is covered thereout with a thermoplastic material layer. The hollow guiderail panel is corrosion-resistant, has a simplified manufacturing process, and ensures vehicle and personnel safety by adsorbing impact energies.

The invention discloses a wave-piercing type side wall hovercraft which comprises a hovercraft body, a front apron, a middle apron, a rear apron and air cushions arranged among the front apron, the middle apron and the rear apron, wherein the front apron, the middle apron and the rear apron are arranged on the lower portion of the hovercraft body. The flat bow design of a traditional air bag typeapron and a ship body is thoroughly changed, the ship bottom is designed to be a variant quadruple ship, the traditional air bag type apron is replaced with the jet type apron, high-frequency vibration of sailing under the sea condition is overcome, and sailing stability under the set sea condition can be achieved; the problem of air leakage between the apron and the water surface is solved, and air supplementing energy consumption is reduced; the lifting pressure is increased, so that the displacement is greatly improved; wave-making resistance of waves to the ship is reduced through wave-shaped design navigation of the prow, the navigation adaptability on the sea surface is further optimized on the basis of a side wall hovercraft, and the sea condition navigation level is improved.
