Description

Polyurethane passive door of going into family with security protection monitor function Technical Field The invention relates to the technical field of passive doors, in particular to a polyurethane passive door with a security monitoring function. Background With the increase of the building quantity of urban buildings, the urban heat island effect becomes more serious, the urban heat island increases the temperature of the whole city, the energy consumption of the air conditioner is further increased, and the passive low-energy-consumption building cannot generate the heat island effect. If a plurality of common buildings generating the heat island effect are changed into low-energy-consumption buildings, the heat islands are eliminated one by one. In order to better reduce the energy consumption and reduce the harm caused by the heat island effect, the concept of 'passive house' building is proposed based on low-energy building in the last 80 th century in Germany. 'the passive house' is a building which realizes constant temperature, constant humidity, constant oxygen, constant net and constant static in four seasons indoors through renewable energy sources such as ground, wall, door and window heat preservation and insulation, fresh air system, solar energy, geothermal energy and the like. Compared with the traditional building, the passive building can save more than 90 percent of energy consumption. At present, although the wooden door has natural appearance, poor heat preservation and sound insulation effects, is easy to be wet and deformed, has insufficient durability, has strong anti-theft performance, has overlarge dead weight, increases the burden of a hinge and a door frame, has high heat conductivity coefficient, is easy to form condensation and frosting in winter, has obvious heat bridge effect, and is mainly made of rock wool, common foaming materials and the like as filling layers, but the rock wool is easy to absorb water to cause the reduction of heat preservation performance, has poor flame retardance, is easy to melt when meeting fire, has potential safety hazard, has simple sealing structure, and is difficult to simultaneously satisfy the heat preservation and sound insulation requirements. In addition, the traditional entrance door has single function, only has basic anti-theft or sound insulation functions, lacks intelligent security monitoring means, and cannot meet the requirements of modern families on safety and convenience. In the prior art, although a door body filled with polyurethane is adopted, only the heat insulation performance is often concerned, the door body is not integrated with a security monitoring system, the sealing between door leaves is mostly dependent on a single-channel sealing strip, and the sealing is not tight due to the deformation of the door leaves or the abrasion of hardware after long-term use, so that the air tightness is influenced. Therefore, a door which meets the requirements of heat preservation and air tightness of a passive building, has intelligent security monitoring function, is light and high in strength, and solves the defects in the prior art is needed. Disclosure of Invention In order to overcome the defects in the prior art, the embodiment of the invention provides a polyurethane passive home door with a security monitoring function, and solves the problems in the background art by arranging a pressurizing assembly. In order to achieve the above purpose, the invention provides the technical scheme that the polyurethane passive door with the security monitoring function comprises a door frame, wherein the door frame is formed by combining a plurality of sectional materials, two door leaves hinged with the door frame and symmetrically distributed, and the polyurethane passive door further comprises: the monitoring part is arranged on one of the door leaves and is used for monitoring the front of the door frame in real time and automatically identifying strangers who stay for a long time; The heat preservation part comprises sealing strips arranged between the door frame and the door leaves, the sealing strips are also arranged at the similar ends of the two door leaves and used for reducing the gap between the door frame and the door leaves, polyurethane materials are filled in the door frame and the door leaves and used for reducing the quality of the door frame and the door leaves, improving the heat preservation and waterproof effects when the door leaves are closed and reducing the indoor heat loss; The pressurizing assembly comprises a rotating shaft which is rotationally connected with one door leaf, the rotating shaft is perpendicular to the end face of the door leaf, a shell is rotationally connected to the rotating shaft, the shell is perpendicular to the end face of the door leaf, a clamping block which can be matched with the end part of the shell is arranged on the other door leaf, the clamping block is L-shaped, the lower
