Description
Technical Field
[0001] The utility model relates to the field of civil air defense engineering, in particular to a gas-proof closed room of civil air defense engineering. Background Art
[0002] The civil air defense basement is an important part of the civil air defense project, which includes outer walls, buffer walls, explosion-proof doors and other parts. In normal times, it can be used as a spare room such as an underground parking garage to solve the increasingly prominent parking problem, while taking into account the peacetime use functions, combining flat stations and giving full play to the combat readiness benefits, social benefits and economic benefits of the civil air defense project; in wartime, it can be used as a temporary shelter for civil air defense, wartime air defense command center, communication center and confined places, etc.
[0003] In civil air defense projects, in order to ensure the air quality in civil air defense projects, anti-gas passages are usually set up. Specifically, exhaust devices and exhaust devices are set up in the anti-gas passage. In addition, the Chinese patent with application number 2021221440717 discloses an explosion-proof, anti-gas and waterproof civil air defense door, the door box is a rectangular box; double-peak seals are installed on the sides of the door box near the back; emergency airbags are installed on the sides of the door box near the front; an inflation chamber is provided at a corner position at the lower front of the door; an airbag gas generator is provided inside the inflation chamber; the airbag gas generator is connected to the emergency airbag; a battery is provided on the airbag gas generator; an airbag trigger switch is provided at the front of the door box relative to the airbag gas generator; an oxygen chamber is provided at another corner position at the lower front of the door; an oxygen tank is installed in the oxygen chamber; an electric control valve is provided at the top of the oxygen tank; and an oxygen tube is connected to the outlet of the electric control valve. Among the above-mentioned civil air defense and anti-gas methods, the use of exhaust ventilation cannot isolate the toxic gas from the safe area, and the toxic gas will still spread to other directions during the extraction process; and installing oxygen tanks on the civil air defense doors, although they can provide oxygen for people in the passage, cannot quickly detoxify and disinfect the air in the passage. Summary of the invention
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a gas-proof closed chamber for civil air defense projects, so as to solve the problem that the existing civil air defense projects lack a gas-proof closed chamber which can not only quickly discharge the poisonous gas but also isolate the poisonous gas in the civil air defense passage and disinfect the passage.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A gas-proof closed room in a civil air defense project comprises a civil air defense passage and a gas-proof passage located on the civil air defense passage, a civil air defense door is installed in the civil air defense passage, and an exhaust device for extracting poisonous gas is provided in the gas-proof passage; at least one normally-open isolation door is also installed on one side of the civil air defense door and in the civil air defense passage, a top plate is sealedly connected between a door frame of the civil air defense door and a door frame of the normally-open isolation door and / or between two adjacent normally-open isolation door frames, and the width of the top plate is equal to the width of the civil air defense passage; after the civil air defense door and the normally-open isolation door are closed, they form at least one gas-proof closed room together with the top plate and the section of the civil air defense passage, and a plurality of nozzles capable of uniformly spraying disinfectant into the enclosed space of the gas-proof closed room are installed on the top plate; a suction branch pipe connected to the suction air duct of the exhaust device is provided in the gas-proof passage, and the suction branch pipe penetrates the top plate and extends into the gas-proof closed room. In this way, after adding a normally open isolation door in the civil air defense passage, the normally open isolation door can be kept open when there is no poisonous gas, which will not affect the normal use of the civil air defense passage. When poisonous gas enters the civil air defense passage, the normally open isolation door and the civil air defense door can be closed, and a gas-proof closed room is formed between the civil air defense door and the normally open isolation door to isolate the poisonous gas outside the gas-proof closed room. After the top plate is set between the door frames, the top of the gas-proof closed room is sealed by the top plate and the door frame, and the side wall and the ground of the civil air defense passage form a side and ground seal, which can effectively ensure the overall sealing performance of the closed room. In the gas-proof passage above the gas-proof closed room, an exhaust device is provided, so that the harmful gas in the gas-proof closed room can be extracted in real time. Compared with the entire civil air defense passage, the space of the gas-proof closed room is smaller, and the harmful gas can be quickly extracted. The nozzle set on the top plate can spray disinfectant on the space of the gas-proof closed room, thereby disinfecting the space and the clothes of the people in the space.
[0007] Furthermore, the normally open isolation door is provided with two, including a first isolation door and a second isolation door, the second isolation door is located between the first isolation door and the civil air defense door; when the civil air defense door and the first isolation door and the second isolation door are in a closed state, a first anti-gas sealed room is formed between the first isolation door and the second isolation door, and a second anti-gas sealed room is formed between the second isolation door and the civil air defense door. In this way, after two normally open isolation doors are provided, two anti-gas sealed rooms can be formed, and the anti-gas sealed room away from the direction where the poisonous gas enters has a better anti-gas sealing effect and higher safety performance.
[0008] Furthermore, at least one fan is installed on the side of the civil air defense door and the first isolation door facing away from the second isolation door. In this way, after the fan is installed, the poisonous gas can be blown outward, reducing the entry of the poisonous gas and improving the poisonous gas isolation effect.
[0009] Furthermore, the first isolation door and the second isolation door are both double-leaf civil air defense doors, including a left door leaf and a right door leaf, and a door leaf sealing strip is embedded on the outer edges of the left door leaf and the right door leaf, and a door frame sealing strip is provided on the door frames of the first isolation door and the second isolation door. In this way, the opening and closing of the double-leaf civil air defense door is more labor-saving, and the provided sealing strip can achieve a good sealing effect.
[0010] Furthermore, a poison gas detector is installed on the upper end of the door frame of the first isolation door and the upper end of the door frame of the civil air defense door. In this way, the poison gas detector can detect harmful gases as soon as they enter the civil air defense passage and give an alarm, so that the personnel in the civil air defense passage can respond quickly.
[0011] Furthermore, at least one disinfectant tank is placed in the anti-gas passage, and a liquid outlet pipe is provided at the lower end of the disinfectant tank, and a plurality of liquid distribution pipes connected thereto are installed on the liquid outlet pipe, and the liquid distribution pipes are connected to each nozzle to provide disinfectant to the nozzle; a solenoid valve is provided on the liquid outlet pipe.

[0019] like Figure 1-Figure 4As shown, the present embodiment provides a gas-proof closed room of a civil air defense project, comprising a civil air defense passage 1 and a gas-proof passage 2 located on the civil air defense passage 1, a civil air defense door 3 is installed in the civil air defense passage 1, and an exhaust device for extracting poisonous gas is provided in the gas-proof passage 2; at least one normally open isolation door 4 is also installed on one side of the civil air defense door 3 and in the civil air defense passage 1, a top plate 5 is sealedly connected between the civil air defense door frame 31 and the normally open isolation door frame 41 and / or between two adjacent normally open isolation door frames 41, and the width of the top plate 5 is equal to the width of the civil air defense passage 1; after the civil air defense door 3 and the normally open isolation door 4 are closed, they form at least one gas-proof closed room together with the top plate 5 and the section of the civil air defense passage 1, and a plurality of nozzles 51 capable of uniformly spraying disinfectant into the enclosed space of the gas-proof closed room are installed on the top plate 5; a suction branch pipe connected to the suction air duct of the exhaust device is provided in the gas-proof passage 2, and the suction branch pipe passes through the top plate 5 and extends into the gas-proof closed room. In this way, after the normally open isolation door 4 is added in the civil air defense passage 1, the normally open isolation door 4 can be opened all the time when there is no poisonous gas, which will not affect the normal use of the civil air defense passage 1. When poisonous gas enters the civil air defense passage 1, the normally open isolation door 4 and the civil air defense door 3 can be closed, and a gas-proof closed room is formed between the civil air defense door 3 and the normally open isolation door 4 to isolate the poisonous gas outside the gas-proof closed room. After the top plate 5 is set between the door frames, the top of the gas-proof closed room is sealed by the top plate 5 and the door frame, and the side wall and the ground of the civil air defense passage 1 form a side and ground seal, which can effectively ensure the sealing performance of the closed room as a whole. And in the gas-proof passage 2 above the gas-proof closed room, an exhaust device is provided, so that the harmful gas in the gas-proof closed room can be extracted in real time. Relative to the entire civil air defense passage 1, the space of the gas-proof closed room is smaller, and the harmful gas can be quickly extracted. The nozzle 51 disposed on the top plate 5 can spray disinfectant on the anti-gas enclosed room space, thereby disinfecting the space and the clothes of the people in the space.
[0020] Specifically, in this embodiment, there are two normally open isolation doors 4, including a first isolation door 42 and a second isolation door 43, wherein the second isolation door 43 is located between the first isolation door 42 and the civil air defense door 3; when the civil air defense door 3 and the first isolation door 42 and the second isolation door 43 are in a closed state, a first anti-gas sealed room is formed between the first isolation door 42 and the second isolation door 43, and a second anti-gas sealed room is formed between the second isolation door 43 and the civil air defense door 3. In this way, after two normally open isolation doors 4 are provided, two anti-gas sealed rooms can be formed, and the anti-gas sealed room away from the direction where the poisonous gas enters has a better anti-gas sealing effect and higher safety performance. Of course, in a specific implementation, only one isolation door may be provided.
[0021] In order to quickly disperse the poisonous gas outside the anti-gas closed room and prevent the poisonous gas from entering, at least one fan 6 is installed on the side of the civil air defense door 3 and the first isolation door 42 facing away from the second isolation door 43. Of course, in order to realize intelligent control, in the specific implementation, a sensor can be set on the door frame of the first isolation door 42 to detect the opening and closing of the door leaf. When the first isolation door 42 is closed, each fan 6 is controlled to start by a controller, and the fan 6 is turned off after the first isolation door 42 is opened or after a certain time of starting.

The opening and closing between the left door leaf and the right door leaf can adopt the existing opening and closing structure of the double-leaf civil air defense door, which will not be described in detail here.
[0023] Furthermore, a poisonous gas detector (not shown) is installed on the upper end of the door frame of the first isolation door 42 and the upper end of the door frame of the civil air defense door 31. In this way, the poisonous gas detector can detect harmful gases as soon as they enter the civil air defense passage 1 and give an alarm, so that the personnel in the civil air defense passage 1 can respond quickly.
[0024] Furthermore, at least one disinfectant tank 52 is placed in the anti-gas passage 2, and a liquid outlet pipe is provided at the lower end of the disinfectant tank 52, and a plurality of liquid dispensing pipes connected thereto are installed on the liquid outlet pipe, and the liquid dispensing pipes are connected to each nozzle 51 to provide disinfectant to the nozzle 51; a solenoid valve is provided on the liquid outlet pipe. In this way, each nozzle 51 is directly connected to the disinfectant tank 52; so that disinfectant can be continuously provided to disinfect the closed room, thereby preventing the poisonous gas from continuing to spread.
[0025] Furthermore, a first chamber and a second chamber are provided on the normally open isolation door 4, and a plurality of gas masks and oxygen tanks are placed in the first chamber and the second chamber, respectively. In this way, after the gas masks and oxygen tanks are provided, the gas masks and oxygen tanks can be removed for oxygen inhalation just after entering the closed room or approaching the isolation door.
[0026] In addition, for the first isolation door 42 and the second isolation door 43, since they are normally open and the lower end of the door leaf is a certain distance from the ground, in order to avoid the door leaf from tilting or loosening after long-term use, a grounding support can be set on the front or back of the left door leaf and the right door leaf. The grounding support includes a grounding screw and a threaded barrel fixed on the door leaf. When in use, the height of the grounding screw can be adjusted by rotating it so that its lower end contacts the ground, thereby providing support for the door leaf.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
