Protective door with function of resisting impact of small aircrafts

Abstract

The invention discloses a protective door with a function of resisting the impact of small aircrafts. The protective door comprises a left side door and a right side door; the bottoms of the left sidedoor and the right side door roll on a lower guide rail respectively by means of two travelling wheels; the tops of the left side door and the right side door roll on an upper guide rail respectivelyby means of two upper guide wheels; the left side door and the right side door are respectively provided with drive motors used for driving the travelling wheels to rotate; two electromagnetic locksare arranged on the wall above a middle door seam when the left side door and the right side door are in a closed state; lock holes, corresponding to the two electromagnetic locks, are respectively formed in the tops of the left side door and the right side door; an enhancement structure is arranged between the opposite sides of the left side door and the right side door. The whole structural strength of the protective door is improved, and the protection intensity of the protective door is especially improved when the protective door is closed; the protective door has the functions of resisting the impact of the small aircrafts, resisting the wind pressure of tornado, and defending flying projectiles of the tornado, thus meeting the special use requirements of a nuclear power plant for the protective door.

Description

technical field [0001] The invention relates to an anti-small aircraft impact protective door, which belongs to the technical field of nuclear power plant protective doors. Background technique [0002] With the development of new energy in the world, nuclear power, as a clean energy, has become the main development direction of today's energy field. The nuclear power industry is growing relatively rapidly, but the safety of nuclear power is indeed the top priority of nuclear power applications; the protective door is a kind of Doors that can resist various shock waves or heavy objects are generally made of steel materials. Among them, radiation protection, fire protection, and explosion resistance are all key performance indicators for doors used in nuclear power plants. , explosion-proof, anti-shock wave, etc.) There is no perfect design specification, most of them adopt some industrial door design experience, design and manufacture according to the working conditions of n...

[0002] With the development of new energy in the world, nuclear power, as a clean energy, has become the main development direction of today's energy field. The nuclear power industry is growing relatively rapidly, but the safety of nuclear power is indeed the top priority of nuclear power applications; the protective door is a kind of Doors that can resist various shock waves or heavy objects are generally made of steel materials. Among them, radiation protection, fire protection, and explosion resistance are all key performance indicators for doors used in nuclear power plants. , explosion-proof, anti-shock wave, etc.) There is no perfect design specification, most of them adopt some industrial door design experience, design and manufacture according to the working conditions of nuclear power plants, which makes it not fully applicable to the requirements of nuclear power plants, resulting in inconvenient operation and poor protection effect , the safety factor is low; at the same time, each part of the nuclear power plant has different requirements for protective doors. Therefore, it is necessary to design a variety of more secure, reliable, and stable protective doors to solve the above problems and meet the special requirements of nuclear power plants for protective doors.
