Embodiment 1

[0034] A two-way sealed air intake closing device, mainly composed of a door panel frame 1, an electric and transmission control box 2, a motor 3, a horizontal bevel gear 4, a vertical bevel gear 5, a shift mechanism 6, a rotating shaft 7, and a rotating swing arm 8 , manual rotating block 9, iron window net 10, sealing line 11, universal joint 12, sealing door panel 13 are formed.

[0035]When the motor 3 rotates, it drives the horizontal bevel gear 4 to rotate, and at the same time drives the vertical bevel gear 5 to rotate, so that the rotating shaft 7 and the rotating swing arm 8 rotate, and the rotating swing arm 8 drives the universal joint 12 and the sealed door panel 13 to rotate together , to realize the opening and closing of the airtight door panel 13. When the rotating swing arm 8 rotates to drive the sealing door panel 13 to close, through the self-adaptive function of the universal joint 12, the rubber sealing strip 14 and the sealing line 11 are compressed to ac...

Embodiment 2

[0037] A two-way sealed air intake closing device, mainly composed of a door panel frame 1, an electric and transmission control box 2, a motor 3, a horizontal bevel gear 4, a vertical bevel gear 5, a shift mechanism 6, a rotating shaft 7, and a rotating swing arm 8 , manual rotating block 9, iron window net 10, sealing line 11, universal joint 12, sealing door panel 13 are formed.

[0038] In the case of all control failures, the horizontal bevel gear 4 is slid out of the meshing of the vertical bevel gear 5. At this time, the rotation of the motor 3 is invalid, and the manual rotation block 9 at the upper end of the rotating shaft 7 can be manually rotated with a wrench to realize all control failures. Under certain circumstances, the closing function can be opened and closed on the spot by a manual wrench. The maximum opening of the valve plate is 80 degrees, the manual closing time is 10 seconds, the manual opening time is 5 seconds, the airtight two-way pressure is 1500Pa...

Embodiment 3

[0040] A two-way sealed air intake closing device, mainly composed of a door panel frame 1, a heat-insulated electric and transmission control box 2, a motor 3, a horizontal bevel gear 4, a vertical bevel gear 5, a shift mechanism 6, a rotating shaft 7, and a rotary pendulum Arm 8, manual rotating block 9, iron window net 10, high temperature resistant sealing line 11, universal joint 12, sealing door panel 13 are formed.

[0041] Under the condition of 280°C fire and smoke exhaust, the door panel will not be closed automatically. After the smoke exhaust is completed, the motor 3 can still rotate to drive the horizontal bevel gear 4 to rotate, and at the same time drive the vertical bevel gear 5 to rotate, so that the rotating shaft 7, The rotating swing arm 8 rotates, and the rotating swing arm 8 drives the universal joint 12 and the sealing door panel 13 to rotate together to realize the closing of the sealing door panel 13 . When the rotating swing arm 8 rotates to drive th...

Abstract

The invention discloses a bi-directionally-sealed air inflow closing device and a method. The bi-directionally-sealed air inflow closing device comprises a door plate frame (1), a sealing door plate (13), a rotating shaft (7) and a rotary swing arm (8); the rotating shaft (7) is connected with a first driving mechanism, a second driving mechanism and a gear-shifting mechanism (6); and the gear-shifting mechanism (6) is used for switching connection between the first driving mechanism and the rotating shaft (7) and connection between the second driving mechanism and the rotating shaft (7). According to the device and the method, when rotating, a motor drives a horizontal bevel gear to rotate and meanwhile drives a vertical bevel gear to rotate, and thus the rotating shaft and the rotary swing arm rotate to achieve opening and closing of a sealing door; and when the manual gear-shifting mechanism is operated, the horizontal bevel gear is slidably disengaged from the vertical bevel gear, at the moment, motor rotation is invalid, and a wrench can be used for manually rotating a manual rotating block at the upper end of the rotating shaft to start the closing function on the spot through the manual wrench in the case of all control failures.

Description

technical field [0001] The invention relates to the technical field of opening and closing of a door cover, in particular to a two-way sealing air intake closing device and a method thereof. Background technique [0002] Vents are installed in ultra-clean pharmaceutical workshops, sterile operating rooms, and many places on ships. Generally, they are opened to facilitate effective ventilation, keep indoor air in a state of circulation, and meet daily ventilation needs. When there is harmful polluting gas outdoors, it is necessary to close the vents in time. The opening and closing of all ventilation windows and doors should be fully automatic program-controlled, and the occasional faulty windows and doors should be manually opened and closed as a backup. [0003] The air intake closing device in the past usually uses a pneumatic valve belt to control the opening and closing of the door cover, such as the patent CN101799088B centralized air intake closing device, which has a...
