The invention provides a building with the fire extinguishing and rescuing function. Rope unreeling equipment is arranged above the building and comprises an electric rope reeling device and a cantilever. The electric rope reeling device is arranged on the cantilever and comprises a rope reel, a gear or a chain belt or a transmission belt or a transmission shaft and a motor. The motor is connected with the periphery of the middle portion of the rope reel through the gear or the chain belt or the transmission belt or the transmission shaft and can drive the rope reel to rotate. An inner through hole is formed in the rope reel.

The invention discloses a system with extinguishment and rescue functions, which comprises rope releasing equipment, and a fire-fighting lance or an extinguishment spray gun or a ventilation tuyere or a connecting piece, wherein the rope releasing equipment comprises an electric rope winder and cantilevers; pulleys are arranged on the cantilevers; the electric rope winder comprises rope winding barrels; ropes penetrate through inner holes of the rope winder and extend out of the two ends of the rope winder respectively to form a first pulling rope and a second pulling rope; and the first pulling rope and the second pulling rope extend out of inner holes of the two ends of the rope winding barrels, are wound for a plurality of circles on the rope winding barrels in the same direction, then extend out of the rope winding barrels, round the pulleys on the cantilevers, and then are wound on rope winding trays respectively or wound into coils or folded into bundles.

The invention relates to an all-plastic diaphragm-type one-way air-exhaust check valve with the emergency ventilation function. The all-plastic diaphragm-type one-way air-exhaust check valve comprisesa valve body, a first valve plate mounting cavity and an air purifying assembly mounting cavity are arranged in the valve body, an outer clamping buckling fastening piece is arranged on the side faceof the valve body, an air exhaust opening is formed in the outer clamping buckling fastening piece, a first valve plate is mounted in the first valve plate mounting cavity, a supporting piece is arranged at the lower portion of the first valve plate, a plurality of hollow parts and supporting reinforcing parts are arranged on the supporting piece, an air exhaust crack is formed in the first valveplate, the air exhaust crack divides the first valve plate into a plurality of air exhaust valve clacks, a dome part is arranged on the position, located at the upper portion of the first valve platemounting cavity, of the side face of the valve body, and a supporting piece damaging column is fixed on the inner wall of the dome part. Under the emergency state of losing the air source of the valve, the one-way non-return function of the first valve plate can be quickly transformed through hard pressing of the dome part of the valve body, meanwhile, a second valve plate sealing structure can be quickly destroyed manually, the two-way flow of the air flow is achieved accordingly, and the breathing need of a wearer under the emergency state is met.

The invention discloses a building provided with a fire-fighting and rescue system. A cantilever component is arranged in a set position on the upper portion of the building. An anti-disengagement pulley is arranged on the cantilever component. The cantilever component can be controlled to drop and extend a rope wound on the anti-disengagement pulley. The cantilever component can be controlled to act on a storey on the lower portion of the building or the outside of the building, so that the rope is dropped and extended to the lower portion of the building along the outer side of an outer wall of the building and hung on the anti-disengagement pulley. A structure on the lower portion of the building or the ground at the bottom of the building or an auxiliary storey roof of the building is provided with a steering pulley or a steering pull ring or a steering pull rod or a steering roller.

Provided is building rope pay-off equipment with an extinguishment rescue function. The rope pay-off equipment comprises an electric roper winder, cantilevers and a box. The box is arranged on the cantilevers, and a supporting plate capable of being opened is arranged below the box. Pulleys or rotating discs or rotating shafts or rollers or hanging and pulling supporting pieces are arranged on the cantilevers or the box. The electric roper winder comprises a rope winding drum, a gear or chain belt or transmission belt or transmission shaft and a motor. The motor is connected with the periphery of the middle of the rope winding drum through the gear or chain belt or transmission belt or transmission shaft and can drive the rope winding drum to rotate. An inner through hole is formed inside the rope winding drum. A controller or control switch or control rope can be used outside the pay-off equipment for controlling the rope winding drum to rotate.

The embodiment of the invention discloses a method for adjusting the replacing point of a breathing machine. The venting amount of a user is monitored in real time, so that the demarcation point of expiration and inspiration of the user is determined; the replacing point of the breaching machine is adjusted according to the relation between the time corresponding to the demarcation point and breathing machine replacing time. When the time corresponding to the demarcation point is larger than the replacing point time, it indicates that replacement is too fast, the specific value of flow corresponding to the replacing time and inspiration peak flow is reduced, otherwise, the specific value is increased in a certain proportion. The replacing point of the breathing machine is adjusted in time, it is ensured that the breathing action of the user is consistent with replacement of the breathing machine to meet the breathing needs of the user, the use experience of the user is improved, the comfort of a respiratory disease patient can be increased, and the treatment quality of respiratory diseases can be improved. In addition, the embodiment of the invention provides a corresponding implementation device and the noninvasive breathing machine. The method is more practical, and the device and the noninvasive breathing machine have corresponding advantages.
