The warm-keeping house aims to solve the problems that power consumption is large and potential safetyhazards exist due to the fact that electric heaters and other independent heating products need to be used due to the fact that an existing portable house does not have an independent heating function when used in the northeast of China, environmental protection is poor and the construction difficulty is large due to the fact that a portable house with a heat preservation layer is made of organicheat preservation materials and a common portable house is not provided with the heat preservation layer, the potential safety hazard of safe sinking exists when the portable house is used on the river surface due to heavy weight, and the appearance and color are single. According to the warm-keeping house, a wall body is sequentially provided with a shell, a waterproof layer, the heat preservation layer, a single-phase counter-heating layer, a graphene electric heating layer and a heat conduction layer from outside to inside, the wall surface can achieve the self-heating purpose, and the heat preservation performance is better; and a joint transition position between the wall body and a door and window adopts a sealing system formed by two new materials of a waterproof vapor-proof film and a waterproof vapor-permeable film, so that the airtightness of the warm-keeping house is improved, and the warm-keeping function is enhanced.

Saline-alkali-resistant soil buried protection pipe integrated control cable
PendingCN113130125ASave process and materialGood waterproof and corrosion resistanceInsulated cablesCable installations in underground tubesAlkali soilSoil science
The invention discloses a saline-alkali-resistant soil buried protection pipe integrated control cable. The cable comprises a cable body, a plurality of groups of cable cores are uniformly distributed in the cable body, the outer rings of the plurality of groups of cable cores are wrapped with a belting layer, the outer side of the belting layer is provided with an aramid fiber reinforcement layer, the outer side of the aramid fiber reinforcement layer is sleeved with an expansion sheath, the expansion sheath is attached to the inner side of a metal shielding pipe, a blocking layer is arranged on the outer side of the metal shielding pipe, and a low-density oil cavity is formed in the lower half area between the blocking layer and the metal shielding pipe. According to the saline-alkali-resistant soil buried protection pipe integrated control cable, the cable and the outer protection pipe are combined together to form an integrated structure, on one hand, the procedure of independently sleeving the protection pipe is reduced, on the other hand, the metal pipe is directly used as an armored shielding layer of the cable, the procedure and materials for installing the armored shielding layer of the cable are reduced, and the cable is suitable for different working conditions and brings better use prospects.
