Description

Chemical protection system with retractable air inlet control valve {INTEGRATED PROTECTION SYSTEM FOR NUCLEAR BIOLOGICAL AND CHEMICAL WARFARE WITH VALVE FOR OPEN OR CLOSE CONTROL TYPE OF AIR INFLOW}

The present invention relates to a CBR protection system having a retractable air inlet control valve. More specifically, uniform pressure is applied to the entire circumference of an external air inlet of an air conditioning system, and airtightness is ensured even at a small pressure. The present invention relates to a NPS protective system having an open / close air inlet control valve which can completely block external polluted air in a NBC situation to ensure safety of a space in an NBC collective protection facility or an enclosed shelter.

In general, CBR refers to wars using chemical weapons such as poison gas, biological weapons such as bacteria, and nuclear weapons such as radiation and radioactivity.

The concept of protection in CBR is divided into personal protection and group protection. Personal protection is performed by wearing personal equipment such as a gas mask that protects a person's face and respiratory system, and a protective clothing that protects the skin by blocking polluted atmosphere. Temporary protection refers to the form of temporary protection, where group protection is a form of protection provided by NBC group protection facilities or enclosed shelters designed for disaster protection, decontamination and treatment under CBR for at least 40 persons for at least 14 days.

Among them, a CBR protection system is installed in a CBR collective protection facility or an enclosed shelter. This NBC protection system includes a NBC defense device that sucks, filters and purifies external polluted air in a NBC situation, and an air conditioning system for indoor air conditioning.

As the NBC defense device, a positive pressure device is adopted to block the inflow of polluted air from the outside by keeping the air pressure in the NBC collective protection facility or the sealed shelter higher than the outside air pressure. In order to provide a comfortable air-conditioning environment, the air flowing through the external air inlet by the blower is selectively passed through the evaporator or the heater, and then the air is supplied to the room through the air duct to cool or heat the sealed shelter.

Therefore, when CBR discharge occurs, the positive pressure device is activated, and the air purged into the room by the positive pressure device is introduced, so that the positive pressure is generated higher than the outside air at this time. There should be no. To this end, the air-conditioning device is provided with an air inlet control valve having a structure in which a cover plate of a rectangular plate is turned off by an driving motor to block an external air inlet port.

Therefore, in normal times, the outside air inlet is opened by the air inlet control valve to allow the fresh air to flow into the room, thereby creating an indoor air conditioning environment, and in the event of a chemical discharge, shut off the external air inlet by the air inlet control valve. This prevents outside polluted air from entering the room.

However, the conventional air inlet control valve simply rotates the cover plate only at a predetermined angle regardless of whether the height of the external air inlet or the surface of the airtight gasket is deformed, so it is difficult to expect perfect external air blocking. In addition, in order to increase the pressure of the gasket by simply increasing the rotational force, the weight increases as the drive motor is enlarged, and the excessive compression force that is not uniform on the opposite side of the rotational shaft is not only increased due to the structure that the one side of the external air inlet is rotated and compressed. There is a problem to be applied, which causes a rapid deformation of the gasket and shortens the service life.

The ball screw nut 132 is provided with a screw hole 142a to be assembled with the ball screw shaft 131 of the lifting unit 130. With this structure, the cup-shaped body 121 is moved by the rotation of the ball screw shaft 131. At this time, the cup-shaped body 121 is prevented from being rotated together with the rotation of the ball screw shaft 131 by the guide pin 123 inserted into the through slot 112d of the housing 112 of the valve housing unit 110. As a result, the linear movement is made up and down.

And as can be clearly seen from the enlarged view of the original view in FIG. 3, the lower end of the cup-shaped body 121 is provided with the inclined surface 121a which inclines inwardly downward, and is outside the inclined surface 121a (outer inclined surface) A circumferential groove 121b is formed along the circumference of the upper body 121, and a pair of circular vents 121c facing each other are in communication with the circumferential groove 121b on the inner side (inner slope) of the inclined surface 121a. Formed.

In addition, a sealing member 124 is attached to the outer inclined surface 121a along the circumference of the cup-shaped body 121 to maintain the airtight while sealing the cylindrical groove 121b whose outer side is exposed. Sealing member 124 is made of a thin film shape that can only block the outer side of the cylindrical groove (121b), preferably made of a soft rubber material having elasticity and elasticity. The upper end of the sealing member 124 is attached in a bent state to be inserted into the groove 121d formed in the circumferential direction on the upper side of the outer inclined surface 121a, it can be firmly fixed by the fixing band 125, The lower end of the sealing member 124 is bent to the lower side of the outer inclined surface 121a and attached to the bottom of the cup-shaped body 121.

According to this structure, when positive pressure is formed in the air conditioning case 31 of the air conditioning and heating device 30 by the positive pressure device, the positive pressure is formed inside the cylindrical groove 121b through the air vent 121c of the cup-like body 121. The housing 112 of the valve housing unit 110 is minutely caught in the space and is pushed toward the inner circumferential surface side of the housing 112 of the valve housing unit 110 while the sealing member 124 is inflated outward by the positive pressure. It is in contact with the inner peripheral surface of the contact.

Therefore, the cup-like body 121 according to the present invention can reliably block the air flow while maintaining an airtight state even with a very small contact.

As shown in FIG. 4, the inclined surface 121a is supported while being caught by the engaging jaw 112f formed along the lower inner circumferential surface of the housing 112 of the valve housing unit 110 (see FIG. 3). 121) to limit the descent.

Here, as illustrated in FIG. 4, the upper end of the locking step 112f has a horizontal surface 112f-1 facing inward and an inclined surface 112f-2 extending from the horizontal surface and inclined downward inward, thereby forming a cup-shaped body ( The inclined surface 121a of 121 is in close contact with the inclined surface 112f-2 of the locking step 112f.

At the interface between the horizontal surface 112f-1 and the inclined surface 112f-2 of the locking jaw 112f, a sealing member 114 made of elastic and elastic material for airtightness is inserted into the groove formed along the circumference. Accordingly, when the inclined surface 121a of the cup-shaped body 121 is supported in contact with the inclined surface 112f-2 of the locking jaw 112f, the two sealing members 114 and 125 abut each other, thereby maintaining complete airtightness. Is done.

Lifting Unit 130

The elevating unit 130 is for raising and lowering the air inflow blocking unit 120 according to the rotational direction of the rotation shaft 141a of the drive motor 141. The ball screw that rotates in accordance with the driving of the drive motor 141 is rotated. The pinion coupled to the shaft 131, the ball screw shaft 131 and the ball screw nut 132 linearly moving in accordance with the rotation of the ball screw shaft 131, and the pinion coupled to the rotation shaft 141a of the drive motor 141. Spur gear 133 that meshes with the gear 142 to rotate the ball screw shaft 131 and a ball screw shaft support mounted on the upper surface of the housing 112 of the valve housing unit 110 to support the center of the ball screw shaft. 134 and a bearing 135 for smoothly moving the ball screw nut 132 in a straight line.

According to the lifting unit 130 having such a structure, the pinion gear 142 coupled to the drive shaft 141a rotates while the drive motor 141 is driven to engage the pinion gear 142 with its rotational force. The ball screw nut 132 fastened to the elevating block 122 of the air inlet blocking unit 120 is transferred to the gear 133 and moves up and down linearly along the ball screw shaft 131 (see FIGS. 3 and 4). By doing so), it is possible to move the air inlet blocking unit 120 up and down.

Drive unit 140

The driving unit 140 is for transmitting a driving force to the lifting unit 130, coupled to the drive motor 141 is driven in the forward or reverse direction when the power supply, and the rotating shaft 141a facing downward of the drive motor 141 To support the pinion gear 142 and the driving motor 141 on the support plate 111 of the housing 112 of the valve housing unit 110 by being engaged with the spur gear 133 of the elevating unit 130. It is configured to include a motor support (143).

The motor support 143 is composed of a top plate 143a supporting the bottom surface of the driving motor 141 and a pair of bottom plates 143b spaced apart from both sides of the top plate 143a, and the bottom plate 143b is formed in a depressed shape. The upper and lower ends thereof are fixed to the upper plate 143a and the support plate 111 of the housing 112 by fastening bolts.

The drive unit 140 is located on one side of the upper surface of the valve housing unit 110, as shown in FIG.

Referring to the operation relationship of the air inlet control valve 100 according to the present invention as described above are as follows.

In the NBC situation, that is, in the wartime driving mode, the NBC defense device 20 is operated. At this time, the air-conditioning apparatus 30 can be operated as needed. However, the air inlet control valve 100 installed at the external air inlet 32 in order to block the inflow of external air from the external air inlet 32 of the air conditioning unit 30 regardless of whether the air conditioner 30 is operating or not. ) To operate in the closed state. In other words, when the driving motor 141 is driven in the forward direction, the pinion gear 142 coupled to the driving shaft 141a reduces and transmits the rotational force of the driving shaft 141a to the spur gear 133 of the elevating unit 140. . Accordingly, the ball screw nut 132 moves the cup-shaped body 121 of the air inlet blocking unit 120 while rotating the ball screw shaft 131.

This cup-shaped body 121 is the bottom surface of the housing 112 of the valve housing unit 110 in the state shown in FIG. 3 from the state shown in FIG. 4 along the inner wall surface of the housing 112 of the valve housing unit 110. As it descends, it blocks the inflow of external air by blocking the opening 11c formed in the bottom surface of the housing 112 in contact with the locking step 112f of the inner wall. At this time, the outer circumferential surface of the cup-shaped body 121 is brought into contact with a small and uniform pressure being applied to the engaging jaw 112f of the inner wall of the housing 112, and the housing 112 and the cup-shaped body 121 are contacted at the time of contact. By being in close contact with the sealing members (114, 125 ) provided in the airtight state can be surely maintained. In particular, since the positive pressure is formed in the room during the operation of the NBC 20 and the air conditioner 30, the pressure is formed in the sealing members 114 and 125, which are the contact portions of the housing 112 and the cup-like body 121. As a result, the contact force between the locking jaw 112f of the housing 112 and the cup-shaped body 121 is improved, thereby ensuring a secure sealing property.

 In such a state that the external air inlet 32 of the air conditioning and heating device 30 is blocked by the air inlet control valve 100, the outside contaminated air is filtered and purified by the NBC filter of the NBC 20. It is introduced into the air conditioner 30 in a state.

The air introduced in this way is supplied into the hermetic shelter 10, and when the air conditioner 30 operates, the air duct 36 is selectively passed through the heater 34 or the evaporator 35 of the air conditioner 30. By being supplied into the sealed shelter 10 through the inside, it is possible to create a comfortable environment in the room in a state of completely blocking the outside polluted air. Here, the air inside the hermetic shelter 10 is sucked into the air conditioner 30 through the air circulation port 37 in communication with the air conditioning case 31 of the air conditioner 30 by the blower 33 is heat exchanged Circulated continuously with air

On the other hand, in the non-CBC situation, i.e. in the normal operation mode, the air inlet control is made to close the air inlet 22 of the NBC defense device 20 and open the external air inlet 32 of the air conditioning and heating device 30 at the same time. Operate the valve 100 in the open state.

That is, when the driving motor 141 is driven in the reverse direction, the cup-shaped body 121 is formed along the inner wall of the housing 112 of the valve housing unit 110 in accordance with the rotation of the ball screw shaft 131 by the method described above. As it rises, as shown in FIG. 4, the opening 112c of the bottom of the housing 112 and the air outlet 112e of the side are opened. As a result, the outside air introduced from the outside air inlet 32 of the air conditioning and heating device 30 passes through the mesh network 113 installed at the opening 112c at the bottom of the housing 112, and the air outlet port at the side of the housing 112. After passing through 112e, it is filtered while passing through the air filter 38 of the heating device 30, and the air thus filtered is heat-exchanged by a heat exchanger and then supplied into the sealed shelter 10. The air inside the sealed shelter 10 is introduced into the air conditioner 30 through the air circulation port 37 communicating with the air conditioning case 31 of the air conditioning unit 30 by the blower 33 as in the exhibition operation mode. The air is continuously circulated with some air sucked into the air conditioner 30 through the air inlet control valve 100 to provide a comfortable air-conditioning environment.
