Description

The present invention relates to a shelter emergency ventilator intake / exhaust pipe connection penetration unit and an assembly connection method for easily and economically installing a shelter emergency ventilator in an existing structure and any structure under construction plan.

2. Description of the Related Art Conventionally, various ventilators, configurations and installation methods for installing the ventilators in buildings, and various ventilation operation methods have been devised.

The detachable attachment device of the wireless remote controller shown in Japanese Patent No. 3603349 (Patent Document 1) is used with the existing cable line connection type remote controller that is locked to the remote controller storage surface of the mounting base. After a fixing tool having a thread groove in the wall through hole is inserted, a fastening nut is screwed onto an end portion of the fixing device on the outdoor wall surface side, and the mounting base is fixed to the inner wall surface of the bathroom.

  Moreover, the ventilation fan attachment member shown by Unexamined-Japanese-Patent No. 7-190433 (patent document 2) has a thread part which can be mutually screwed by the through-hole provided in the chamber wall, and the said penetration is carried out at one side edge part. A small-diameter pipe where a ventilation fan body with a flange part larger than the hole diameter is installed and a large-diameter pipe where a vent cap is installed are installed so as to be screwed together, and the small-diameter pipe at the end of the large-diameter pipe is inserted into the part Is a configuration that allows a small distance pipe to be inserted at a certain distance as a part that does not have a threaded portion, and allows the small diameter pipe to be inserted after inserting the tip of the small diameter pipe. is there.

  Moreover, the shelter emergency ventilation apparatus used for this invention is a structure like the shelter emergency ventilation apparatus shown in the disaster prevention shelter pamphlet (nonpatent literature 1) of Uemura Giken Co., Ltd., The structure is mainly an air supply fan. And gas filter, and the gas filter can cope with NBCR disaster, it can remove any impurities in the air that have harmful effects, and the piping connecting the air supply fan and gas filter In order to prevent the unprocessed air of the gas filter from leaking out of the apparatus even if there is an airtight defect portion or the like, it is arranged on the intake side of the air supply fan.

The gas filter untreated air is purified from the gas filter intake port via the gas filter by manually or electrically driving the air supply fan of the shelter emergency ventilation device, and then the gas filter air supply port, Air is supplied to the outside of the machine via the air supply fan inlet and the air supply fan inlet.

  Usually, shelter emergency ventilation equipment is installed as part of crisis management measures to protect people evacuating inside structures and command operators, such as control shelters such as nuclear shelters, nuclear power plants, and chemical factories. While purifying outdoor contaminated air with a shelter emergency ventilator, clean air is sent into the structure to make the air pressure inside the structure positive with respect to atmospheric pressure. It provides positive pressure filtering ventilation that prevents the inflow of material into the room and provides the clean air necessary for people's breathing.

  At this time, the shelter emergency ventilator is connected to a ventilation intake through hole provided at an arbitrary position of the structure wall body, and an optional opening provided at an arbitrary position different from the ventilation intake through hole. Although positive pressure filtering ventilation is performed in cooperation, the degree of positive pressure can be adjusted by adjusting the degree of opening of an arbitrary opening.

  In addition, by applying the shelter emergency ventilation device, clean air is exhausted to the outside while purifying indoor polluted air with the shelter emergency ventilation device, and the atmospheric pressure inside the structure is made negative with respect to atmospheric pressure. It is also possible to provide negative pressure filtering ventilation that prevents people from entering and leaving pollutants from airtight defects and supplies clean air necessary for people's breathing.

  In addition, the shelter emergency ventilator takes into account the degree of opening of the arbitrary opening, the impact of the airtight defect such as damage to windows and doors, cracks in the building, etc. on the degree of positive pressure, As shown in (Non-patent Document 1), a differential pressure measuring device for measuring the differential pressure between the outdoor pressure and the indoor pressure is often separately formed and used together.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  The basic configuration of the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 shown in the present invention is shown in FIGS. 1, 2, and 3, and the operation implementation configuration is shown in FIGS. 4-a, 4-b, 5-a, and 5 -B, the assembly connection procedure is shown in FIGS. 6-a, 6-b, and 6-c, and the intake / exhaust pipe connection part unit 6 and the tension fixing constituting the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 The structure of the unit 7 is shown as a perspective view in FIG. 7A, FIG. 7B, FIG. 8-A, FIG. 8-B, and FIG.

  As shown in FIG. 4-a and FIG. 4-b, FIG. 5-a and FIG. 5-b, there are four possible operation implementation configurations of the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5. There are three important components that are common to the basic configuration.

The first important component is that the shelter emergency ventilator connected to the shelter emergency ventilator intake / exhaust pipe connection penetrating unit 5 is connected to the shelter emergency ventilator air supply fan 30 on the intake side of the shelter emergency ventilator gas filter 31. Even if there is an airtight defect in the piping connecting the shelter emergency ventilator air supply fan 30 and the shelter emergency ventilator gas filter 31, untreated air from the gas filter leaks out of the machine. It is the point which is comprised so that the atmospheric pressure in piping may become a negative pressure so that it may not do.

The second important component is the presence of the arbitrary opening 4. When positive pressure filtering ventilation or negative pressure filtering ventilation is performed by the shelter emergency ventilation device, the size of the arbitrary opening 4 provided in the structure wall 1 is large. By adjusting the degree of positive or negative pressure of the indoor air pressure relative to the atmospheric pressure, such as by providing an overpressure adjustment valve separately, the appropriate positive air pressure can be obtained through cooperation between the shelter emergency ventilator and the optional opening 4. It is a point to perform pressure ventilation or negative pressure ventilation.

For example, in the case of an existing building, the arbitrary opening 4 uses an opening of an existing ventilation fan provided in a kitchen. However, when positive pressure filtering ventilation or negative pressure filtering ventilation is performed, the size of the arbitrary opening 4 is large. When the height is increased, the ventilation resistance is reduced and the differential pressure indicating the degree of positive pressure and negative pressure can be reduced. When the size of the arbitrary opening 4 is reduced, the ventilation resistance is increased and the degree of positive pressure and negative pressure. Can be increased.

  However, the optional opening 4 has an airtight defect when an airtight defect occurs in a part that is difficult to visually recognize, such as when a window or door breaks or a building cracks in an emergency. It should be noted that the degree of differential pressure is reduced by the function of the arbitrary opening 4.

  The third important component is that the differential pressure with respect to the target atmospheric pressure is sufficiently obtained when positive pressure filtering ventilation or negative pressure filtering ventilation is performed in cooperation with the shelter emergency ventilation device and the arbitrary opening 4. In other words, a differential pressure measuring device 35 for managing the differential pressure for ascertaining whether or not is used together.

  The differential pressure measuring device 35 is arranged on the shelter emergency ventilator installation side in FIGS. 4-a, 4-b, 5-a, and 5-b. For example, when the pressure equivalent is managed by visual observation, for example, the shelter emergency ventilation device is installed on the outdoor side to perform positive pressure filtering ventilation. The differential pressure measuring device 35 is not necessarily arranged on the same side as the shelter emergency ventilation device, for example, a person on the indoor side manages the differential pressure by arranging the vessel 35 on the indoor side. Shall be considered each time.

  By satisfying the above three important components, the shelter emergency ventilator intake / exhaust piping connection penetration unit 5 is a basic configuration for providing an effective positive pressure filtering ventilation or negative pressure filtering ventilation effect for any disaster. Can be secured.

  The operation implementation configuration shown in Fig. 4-a is a configuration for performing positive pressure filtering ventilation, which is extremely effective when the outdoor air is contaminated by radioactive particles, toxic gases, harmful viruses, etc., by an armed attack using NBCR weapons. Yes, by using positive pressure filtering ventilation with extremely high harmful substance removal accuracy over a long period of time by shelter emergency ventilator gas filter 31 that responds to NBCR disasters, it is possible to prevent contamination inside the structure and people indoors Can be supplied with safe air.

  The operation implementation configuration shown in FIG. 4B is a configuration for performing negative pressure filtering ventilation, such as a nuclear power plant or an oil complex where substances that may cause harmful pollution to air exist in the structure. Effective negative pressure filtering ventilation with a very high accuracy of removing harmful substances over a long period of time with the shelter emergency ventilator gas filter 31 that responds to NBCR disasters and is effective as a countermeasure against terrorist disasters and accident disasters in Japan It is possible to prevent the contaminated air inside the structure from flowing out to the outside and to adsorb and remove harmful substances floating or mixed in the air inside the structure.

  The operation implementation configuration shown in Fig. 5-a is a configuration for performing positive pressure filtering ventilation, and the outside air is contaminated with radioactive fine particles, toxic gas, harmful viruses, etc. by an armed attack using NBCR weapons, and the inside of the structure It is effective when the space for installing the shelter emergency ventilator cannot be secured, and by performing positive pressure filtering ventilation with extremely high harmful substance removal accuracy over a long period by the shelter emergency ventilator gas filter 31 corresponding to NBCR disaster, Contamination inside the structure can be prevented and safe air can be supplied to evacuees.

  The operation implementation configuration shown in FIG. 5B is a configuration for performing negative pressure filtering ventilation, and a nuclear power plant or biochemical factory in which substances that may cause harmful pollution to air exist in the structure. This is particularly effective as a post-measure for terrorist disaster countermeasures and accident disaster countermeasures, and the post-worker operator can insert the through-hole base hole 2 at any position on the structure wall 1 from the outside of the structure without entering the structure. 3 and 9 and the shelter emergency ventilator intake / exhaust piping connection penetration unit 5 is formed and negative pressure filtering ventilation is performed by the shelter emergency ventilator to cope with NBCR disasters The negative pressure filtering ventilation with extremely high accuracy of removing harmful substances over a long period of time by the shelter emergency ventilator gas filter 31 Air while preventing flow out outdoors, harmful substances floating or mixed structures inside the air can be adsorbed and removed.

  The shelter emergency ventilator intake / exhaust pipe connection penetrating unit 5 can be connected to the shelter emergency ventilator intake / exhaust pipe connection penetrating unit 5 in the through hole base hole 2 provided in the structure wall 1 to connect the shelter emergency ventilator. It is a member for forming the exhaust through-hole 3, and according to the assumed disaster situation, the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 and the shelter emergency as shown in FIGS. 4-a and 5-a A connection configuration for positive pressure filtering ventilation to which the intake port side of the ventilator gas filter 31 is connected, and the shelter emergency ventilator intake / exhaust pipe connection penetrating unit 5 and the shelter as shown in FIGS. Both the connection configuration for negative pressure filtering ventilation to which the air supply port side of the emergency ventilation device air supply fan 30 is connected can be supported.

  The common point of the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 shown in FIGS. 1, 2, and 3 is that the two units penetrate the structure wall 1 as shown in the assembly drawing of FIG. The through hole base hole 2 is formed and the shelter emergency ventilator intake / exhaust pipe connecting through unit 5 is assembled and installed without being influenced by the structure of the structure wall 1.

It can be installed manually from the opening of the through hole base hole 2 on the opposite side, and one side of the structure wall 1 is extremely contaminated with radioactive material, etc., and goes around to the installation side of the tension fixing unit 7 If not, the assembly work can be easily performed, which is economical, and is effective for assembly and installation as a countermeasure for subsequent measures.

  Furthermore, the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 is shown in FIGS. 1, 2, 3, 4, 4-a, 4-b, 5-a, 5-b, 6-a, FIG. 6-b, as shown in FIG. 6-c, one or more internal small-diameter through pipes 24 can be formed, and by using these internal small-diameter through pipes 24, more functional and full-scale defense disaster prevention measures Can be taken.

  Each of the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 shown in FIG. 4-a, FIG. 4-b, FIG. 5-a and FIG. Internal small-diameter through pipe 25 for differential pressure measurement for measuring the differential pressure between the atmospheric pressure and the indoor atmospheric pressure, internal small-diameter through pipe for water supply / drainage for supplying and draining water and other fluids between the indoor side and the outdoor side 26 shows a situation in which an internal small-diameter through pipe 27 for a cable that functions as a sheath pipe for inserting a power cable or a communication cable into the internal small-diameter through pipe 24 and penetrating the cables is provided. Since the internal space of the intake / exhaust through-hole 3 formed by the shelter emergency ventilator intake / exhaust pipe connection / penetration unit 5 is used, it is not necessary to separately form each dedicated through-hole in the structure wall 1. It is economical and can easily and economically take measures while greatly increasing the possibility of responding to diversified disasters, so that it can be quickly formed and responded to even in the event of an emergency response. .

  The most effective use of the internal small-diameter through pipe 24 is a differential pressure that can continuously manage a differential pressure indicating the degree of positive pressure or negative pressure when performing positive pressure filtering ventilation or negative pressure filtering ventilation. This is used as an internal small-diameter through pipe 25 for measurement, which is shown in FIGS. 1, 2, 3, 4-a, 4-b, 5-a, 5-b, 6-a, FIG. 6-b and all of FIG. 6-c.

It is important that the small-diameter pipe connection penetrating member 22 is set at any appropriate position 7 so as not to be affected by the air pressure flowing through the intake / exhaust through-hole 3, for example, the connection side of the differential pressure measuring device 35 shown in FIG. Because the position of the outdoor side opening of the small-diameter pipe connection penetrating member 22 for measuring the differential pressure on the opposite side is easily affected by atmospheric pressure fluctuations due to intake and exhaust, it is considered that accurate differential pressure measurement cannot be performed as it is. The differential pressure measurement pipe member 32 is connected to the opening of the differential pressure measurement pipe 32 and the outdoor side opening of the small diameter pipe connection penetrating member 22, as shown in FIG. Intake and exhaust the opening of the pipe 32 By away from hole 3 sufficiently, it can be measured more accurately the pressure difference.

In addition, as shown in FIGS. 4-a, 4-b, 5-a, and 5-b, an additional usage of the internal small-diameter through-pipe 24 is as follows. The use as the guide through sheath pipe 27 can greatly increase the degree of freedom for securing the infrastructure of a closed system space or an isolated system space after a disaster.

  The internal small-diameter through-pipe 26 for water supply and drainage is used to supply necessary domestic water and wastewater that is no longer necessary when living in an evacuated environment that does not have a water supply / drainage infrastructure or has been damaged. Since it is possible to supply and drain water without forming a new dedicated water and drain through hole in the structure wall 1, it is economical.

  The internal small-diameter through-pipe 27 for cables is a new dedicated cable for performing necessary power and communication when living in an evacuated life where power and communication infrastructure is originally not provided or damaged. Since the cable can be pulled in without forming the through-hole for drawing in the structure wall 1, it is economical.

In addition, the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 is configured such that the position regulating wall surface plate 12 of the intake / exhaust pipe connection part unit 6 and the tension fixing unit 7 is pressed against the wall surface of the structure wall 1 with an appropriate force. Therefore, high airtightness, waterproofness, etc. are secured by sandwiching packing or the like between the wall surface of the structure wall body 1 and the position restriction wall plate 12 or by caulking the edge of the position restriction wall plate 12. can do.

  In addition, as shown in FIGS. 1, 2, 3, 6-b, and 6-c, the shelter emergency ventilator intake / exhaust pipe connection penetration unit 5 is used as an outdoor rain-proof measure, as shown in FIGS. 1, 2, 3, 6-b, and 6-c. A vent cap 17 can be attached to the unit 7.
