DETAILED DESCRIPTION

[0018] like Figure 1 and Figure 3 As shown, the ventilation device for the civil air defense door includes a supporting shell 1, which is arranged in a rectangular hollow cavity, and also includes a baffle 2 and an air supply and ventilation mechanism 3. The baffle 2 is arranged in the middle of the supporting shell 1, and the air supply and ventilation mechanism 3 is arranged between the baffle 2 and the inner wall of the supporting shell 1. The air supply and ventilation mechanism 3 is symmetrically arranged with the baffle 2 as the center. The supporting shell 1 is loaded with symmetrical air supply and ventilation mechanisms 3, and separated by a partition 9, so that one air supply and ventilation mechanism 3 takes in air, and the other air supply and ventilation mechanism 3 supplies air.

[0019] like Figure 1-5 As shown, in order to realize air conversion on both sides of the civil air defense door and increase air flow, the air supply and ventilation mechanism 3 includes a ventilation duct 1 4, a ventilation duct 2 5, an air intake assembly 6 and an adjustment assembly 7. The ventilation duct 1 4 passes through the outer side walls of the supporting shell 1 that are away from each other and is arranged at the upper part of the supporting shell 1. The ventilation duct 2 5 passes through the outer side walls of the supporting shell 1 that are away from each other and is arranged at the lower part of the supporting shell 1. The ventilation duct 1 4 and the ventilation duct 2 5 are symmetrically arranged up and down. The air intake assembly 6 is arranged between the symmetrical ventilation duct 1 4 and the ventilation duct 2 5. The air intake assembly 6 is connected with the ventilation duct 1 4 and the ventilation duct 2 5. The air intake assembly 6 is symmetrically arranged. The adjustment assembly 7 is arranged between the symmetrical air intake assemblies 6. Air enters and exits through the ventilation duct 1 4 and the ventilation duct 2 5. The air intake assembly 6 provides a driving force between the ventilation duct 1 and the ventilation duct 2, and the adjustment assembly 7 is used to realize the switching of wind direction and the adjustment of wind speed.

[0020] like Figure 3-5 As shown, in order to promote the air flow on both sides of the civil air defense door, the air intake assembly 6 includes a connecting pipe 8, a partition 9 and an air pump 10. The connecting pipe 8 is connected between the ventilation duct 1 4 and the ventilation duct 2 5. The connecting pipe 8 is located on both sides of the ventilation duct 1 4 and the ventilation duct 2 5. The connecting pipe 8 is symmetrically arranged. The partition 9 is located in the middle of the connecting pipe 8. The air pump 10 penetrates the partition 9 and is arranged inside the partition 9. The air pump 10 is fixedly installed inside the connecting pipe 8 through the partition 9, and air flows to the ventilation duct 1 4 and the ventilation duct 2 5 through the connecting pipe 8;

[0021] In order to realize the wind direction switching of the air supply and ventilation mechanism 3 on one side, the wind direction and wind speed of the ventilation duct 1 4 and the ventilation duct 2 5 are adjusted by the adjustment component 7. The adjustment component 7 includes a rotating motor 11, a driving wheel 12 and a plug plate 13. The rotating motor 11 is arranged on the outer wall of the primary connecting pipe 8, and the driving wheel 12 is arranged at the output end of the rotating motor 11. The two ends of the plug plate 13 respectively penetrate the ventilation duct 1 4 and the ventilation duct 2 5 and are slidably arranged in the ventilation duct 1 4 and the ventilation duct 2 5. The plug plate 13 is symmetrically arranged with the driving wheel 12 as the center. A rack 14 is arranged at the middle of the inner wall of the symmetrical plug plate 13. The rack 14 is meshed with the driving wheel 12 to drive the rotating motor 11 to rotate. The rotating motor 11 drives the driving wheel 12 to rotate. The driving wheel 12 is meshed with the racks 14 on both sides, so that the symmetrical plug plate 13 moves in the opposite direction in the ventilation duct 1 4 and the ventilation duct 2 5, so as to realize the opening and closing control of the two ends of the ventilation duct 1 4 and the ventilation duct 2 5, and realize the conversion of wind direction and the adjustment of wind speed.

[0022] Among them, filter screens 15 are respectively provided at the connection points between the connecting pipe 8 and the ventilation duct 1 4 and the ventilation duct 2 5, and a limit baffle 16 is provided on the outer wall of the end surface of one end of the supporting shell 1. Mounting holes 17 are opened at the corners of the limit baffle 16, and the mounting holes 17 are symmetrically arranged in pairs. The filter screen 15 is used to filter the obvious dust and impurities in the circulating air of the ventilation duct 1 4 and the ventilation duct 2 5. The limit baffle 16 is used to limit the supporting shell 1, and the device is installed and fixed through the mounting hole 17.

[0023] When in use, the operator inserts the device into the opening of the civil air defense door. When the support shell 1 is inserted into the opening, the limit baffle 16 is used to limit the position and contact the civil air defense door. It is fixed in the civil air defense door through the mounting hole 17 bolt connection. The air supply and ventilation mechanisms 3 symmetrically distributed on both sides of the partition 9 are used for air intake and the other for air outlet.

[0024] In the initial state, the symmetrical plug plates 13 close both ends of the ventilation duct 1 4 and the ventilation duct 2 5. At this time, the air pump 10 cannot supply air to the ventilation duct 1 4 and the ventilation duct 2 5 through the connecting pipe 8. When it is necessary to send the external gas of the civil air defense door into the interior, the driving wheel 12 rotates counterclockwise, and one side of the symmetrical plug plate 13 moves downward, and the other side plug plate 13 moves upward. In the default state, the upper end of the air pump 10 is the air outlet end, and the lower end is the air inlet end. The air pump 10 extracts the gas at one end of the ventilation duct 2 5 through the connecting pipe 8, and the air The body is pumped into the ventilation duct 4 by the air pump 10 through the connecting pipe 8, and is ejected from the other end of the ventilation duct 4 to enter the inner side of the civil defense door, realizing the air intake of the civil defense door. Similarly, the driving wheel 12 rotates clockwise, and air is drawn from one end of the ventilation duct 2 5, drawn through the air pump 10, and ejected from the other end of the ventilation duct 4 to realize the air outlet of the civil defense door, thereby realizing the gas flow on both sides of the civil defense door. When the wind speed needs to be adjusted, the plug plate 13 can be made to not completely block the cross-section of the ventilation duct 4 or the ventilation duct 2 5.
