Description

Technical Field

[0001] The invention belongs to the technical field of air defense bunkers, in particular to a private assembled air defense bunker. Background Art

[0002] An assembled air defense bunker is a type of shelter built by private individuals in an open underground or under a building to protect personal safety. As early as in our country, there was also "deep digging holes and storing food", which can be understood as civil air defense projects used to prevent nuclear strikes. The country has issued many standards for public civil air defense projects in cities, but there has been no protection bunker for private use in rural areas.

[0003] The patent with application number CN202110922094.8 discloses an anti-strike bunker-type building. Although this solution hides the building below the ground to avoid targeted attacks during wartime, at the same time, when the bunker is used, due to the long-term concealment of the bunker, it cannot meet the conditions for people to live in the bunker, and when used normally, it cannot respond to floods and emergency entrances and exits.

[0004] In addition, in existing bunker installations, due to the limited space occupied by the bunker, the water entering the bunker cannot be properly purified. At the same time, due to the special ventilation system in the bunker, it is extremely easy to be damaged in wartime, resulting in insufficient oxygen in the bunker for human survival, causing the bunker to become abandoned. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems. The present invention provides a private assembled air defense bunker, which has the advantages of quick installation and easy operation.

[0006] To achieve the above object, the present invention provides the following technical solutions: a private assembled air-raid bunker, comprising assembled walls, the air-raid bunker formed by the assembled walls has the following safety assurance systems, namely, a bunker protection system, a bunker entry and exit system, an air purification system, a water supply purification system, an oxygen production system and a power supply system;

[0007] The bunker protection system consists of prefabricated walls that bear the impact force when colliding with external objects;

[0008] The bunker access system consists of two entrances and exits, one of which is a vertical ladder emergency entrance and exit, and the other is a corridor inclined ladder common entrance and exit, and the common entrance and exit located on the ground is located on the upper floor of the building;

[0009] The air purification system consists of a circulating filtration and purification system;

[0010] The water purification system is capable of purifying the water entering the bunker;

[0011] The oxygen production system can replenish the oxygen in the bunker when the bunker is in a closed state;

[0012] The power supply system maintains the operation of electrical components in the bunker through solar power generation and power generation.

[0013] The water supply and purification system includes a circulation part for purifying water, one end of the circulation part is connected to an external water source, one side of the circulation part is respectively connected to a purification component and an air supply component, the purification component is close to the water inlet position on the circulation part, the air supply component is located on a side away from the purification component, and the side of the circulation part away from the purification component is connected to an oxygen production component;

[0014] A control component for controlling the water inflow and the operation of the purification component and the oxygen production component is fixedly arranged in the wall of the circulation part;

[0015] The external water source is connected through the circulation part, and then the water flow is introduced into the purification component to complete the purification of the water source. At the same time, the purified water flows into the bunker for storage. At the same time, when the control component detects that the bunker needs oxygen supply, the purified water flows into the oxygen production component, and oxygen is generated by decomposing water molecules, and the generated oxygen is sent out through the air supply component.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The steel grid insulation board is fixed together with the steel plate and steel section. Concrete is poured on both sides of the steel grid insulation board to form a bulletproof wall. The steel structure concrete modular components of the bunker are cast in the factory according to the design size. Ventilation holes and entrances and exits are reserved before pouring. A foundation pit of the design size is dug at the air defense bunker project site. A cushion layer is laid in the foundation pit using concrete and waterproof materials. The assembled components are hoisted into the foundation pit and installed and connected according to the construction process. Ventilation ducts and protective doors are installed at the reserved openings, and then the channel corridor is hoisted to the protective door and connected to the bunker. After all components are installed, an anti-corrosion and waterproof layer is laid on the periphery of the bunker, and then earth is filled on the periphery of the waterproof layer to form an assembled air defense bunker, so that the required system can be installed in the bunker.

[0018] 2. The water that needs to be purified from the outside and inside the bunker flows into the purification component through the circulation part, so as to replenish the water resources in the bunker. At the same time, by hanging the circulation part and the purification component inside the bunker, the space of the purification equipment is greatly reduced, so that the space in the bunker can be reasonably allocated.

[0019] 3. By setting up oxygen production components and air supply components, when the ventilation system of the bunker is damaged, it can still ensure that the oxygen in the bunker is kept within a safe range and maintain the normal movement of people in the bunker.

[0020] 4. The purified water is rationally distributed through the bunker's control center and control components, so that the size of the closing plate can be adjusted according to the oxygen content in the bunker and while ensuring sufficient water circulation in the bunker. At the same time, the oxygen production rate of the oxygen control component is adjusted by the moving distance of the closing plate to maintain the stability of oxygen and water resources in the bunker and achieve the purpose of relatively long-term living in the bunker.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 6As shown, a private assembled air-raid bunker includes assembled walls. The air-raid bunker formed by the assembled walls has the following safety assurance systems, namely, a bunker protection system, a bunker entry and exit system, an air purification system, a water supply purification system, an oxygen production system and a power supply system.

[0030] Bunker protection system: The six sides of the bunker have strong steel-concrete external protection walls to prevent impact objects from causing damage to the bunker walls, thereby maintaining the stability of the bunker and ensuring the personal safety of people inside the bunker.

[0031] Bunker entry and exit device: The entrance and exit of the bunker is the key safety protection entrance of the bunker. Two entrances and exits are reserved in the bunker, one is an emergency entrance and exit with a vertical ladder, and the other is a common entrance and exit using a corridor inclined ladder. There is not only a strong protective door between the bunker and the corridor at the exit of the inclined ladder, but the exit of the corridor also needs to be reserved at a certain height from the ground. If the bunker is built under the villa, it is best to reserve the exit on the ground of the second floor of the villa to prevent water from flowing back into the bunker when the ground is flooded.

[0032] Air purification system: When personnel enter the bunker, the bunker's air circulation, filtration and purification system is turned on to filter harmful gases inside and outside, ensuring that the gas composition in the bunker is always maintained at a level that is harmless to the human body.

[0033] Water supply and purification system: There must be a water storage device in the bunker, and the daily living water in the bunker needs to be recycled and reused by water purification equipment to ensure that there is enough living water in the bunker.

[0034] Oxygen production system: The bunker has been closed and isolated from the outside world for a long time. At the same time, the outside air is not filtered up to standard when entering the bunker, and the oxygen in the room gradually decreases. Of course, an oxygen production system is indispensable in the bunker. The configuration of the oxygen generator is related to the area and personnel of the bunker. In the absence of outside air, the oxygen supply in the bunker is ensured.

[0035] Power supply system: The bunker is equipped with a power generation system, which includes solar power generation and power generation. Solar power generation uses outdoor solar panels to enter the bunker through wires and store electricity. If the power generator is used in an emergency, it will be connected to the power storage device for storage, ensuring long-term power supply function.

[0036] In addition to the systems stated above, the following safeguard systems may also be included, namely:

[0037] Communication system: The communication system includes outdoor video surveillance and antenna devices. The surveillance cameras installed outdoors are connected to the bunker control console. The personnel in the bunker can understand the outdoor situation at any time. The outdoor antenna is connected to the TV to facilitate the understanding of external information. The antenna is connected to the indoor communication equipment to contact the outside world at any time.

[0038] Constant temperature system: The bunker’s outer maintenance structure is equipped with an insulation layer, and the indoor temperature reaches the ultra-low energy consumption standard. Only a small amount of energy from constant temperature air conditioning is needed to make the bunker reach a comfortable temperature.

[0039] Drainage system: The wastewater that cannot be used in the bunker is directly discharged to the outlet above the specified height on the ground outside the bunker through the drainage system to ensure that the drain outlet will not be backflowed by foreign objects.

[0040] Ecological three-dimensional planting system: For long-term residence in the bunker, an ecological three-dimensional planting room should be reserved. The planting room should be equipped with supporting equipment such as optical ultraviolet rays. Not only can the three-dimensional planting ensure fresh vegetables for people in the bunker, but it can also promote the improvement of air quality, thus achieving double benefits from one planting.

[0041] The water supply purification system includes a circulation part 1 for purifying water, wherein the overall shape of the circulation part 1 is "L" shape, one end of the circulation part 1 is connected to an external water source, and a purification component 2 and an air supply component 4 are respectively connected on one side of the circulation part 1, and the purification component 2 and the air supply component 4 are respectively fixedly connected to the circulation part 1, the purification component 2 is close to the water inlet position on the circulation part 1, and the air supply component 4 is located on the side away from the purification component 2, and the side of the circulation part 1 away from the purification component 2 is connected to an oxygen production component 5, that is, the oxygen production component 5 and the air supply component 4 are located on different sides of the circulation part 1.

[0042] A control component for controlling the water intake and the operation of the purification component 2 and the oxygen production component 5 is fixedly disposed in the wall of the circulation part 1, wherein the control component is connected to the control center of the bunker;

[0043] An external water source is connected through one end of the circulation part 1, and then the water flow is introduced into the purification component 2 to complete the purification of the water source. At the same time, the purified water flows into the bunker for storage. At the same time, when the control component detects that the air composition in the bunker has changed and oxygen supply is required, the purified water flows into the oxygen production component 5, and oxygen is generated by decomposing water molecules. At the same time, the generated oxygen is sent into the bunker through the air supply component 4.

[0044] In order to facilitate the circulation part 1 to collect, absorb and purify the external water, the circulation part 1 includes an entry end 11 and a flow end 12, wherein the entry end 11 and the flow end 12 are connected in an "L" shape, and the entry end 11 is penetrated by an entry cavity 1102, so that the water outside or inside the bunker enters the entry end 11, and then flows into the entry cavity 1102 for the next step of work, and the flow end 12 is respectively provided with a flow cavity 1201 and an exhaust cavity 1202, and the flow cavity 1201 and the exhaust cavity 1202 are independent of each other, the entry cavity 1102 and the flow cavity 1201 are communicated with each other, and the purification component 2 and the oxygen production component 5 are communicated with the flow cavity 1201, and a filter plate 1101 is fixedly provided on the side of the entry cavity 1102 away from the flow end 12, and the large impurities floating in the water are preliminarily filtered through the filter plate 1101 to prevent large impurities from entering the device and blocking the flow of water, so that the device cannot be used normally.

[0045] In order to facilitate the removal of purified water from the circulation part 1 and allow the purified water to enter the water circulation system of the bunker, an outflow port 3 is opened on the flow end 12, and the outflow port 3 is connected to the flow chamber 1201. In order to control the outflow rate of the outflow port 3, a baffle is movably provided between the outflow port 3 and the flow chamber 1201, and the baffle can completely block the port of the outflow port 3. At the same time, the movement of the baffle on the outflow port 3 is regulated by the control component. During normal purification, the baffle is fully opened, so that the purified water can all flow out through the outflow port 3. When the control center in the bunker detects that the oxygen content in the bunker is reduced, the baffle on the outflow port 3 is completely closed or partially closed, so that part or all of the water passing through the purification component 2 flows into the oxygen production component 5, so that the water is electrolyzed into oxygen and discharged into the space of the bunker to replenish the oxygen concentration in the bunker.

[0046] In order to achieve rapid purification of external water and reduce the large-scale use of space during purification, the purification component 2 includes a purification box 21, one end of which is fixedly connected to the wall of the flow end 12, and a connecting cavity 26 is opened in the purification box 21. One end of the connecting cavity 26 is connected to a water inlet 2101, and the other end is connected to a static pool 25, wherein a separation plate is fixedly provided in the connecting cavity 26, and the aperture of the separation plate is smaller than the aperture of the filter plate 1101, which can further separate the water flow entering the water purification component 2, and the impurities in the water are precipitated by the static state of the water flow in the static pool 25, so that the water purification is completed, and the static pool 25 is far away from the connecting cavity 26. A water outlet 2102 is provided at one end, wherein the water inlet 2101 is connected to the entrance chamber 1102, and the bottom end of the water inlet 2101 is flush with the bottom surface of the entrance chamber 1102, and the water outlet 2102 is connected to the flow chamber 1201, so that the water flowing through the entrance chamber 1102 enters the clean water tank 21 through the water inlet 2101, and flows obliquely along the connecting chamber 26 in the clean water tank 21, and is further separated and purified through the separation plate, so that the water flows into the stilling pool 25 for sedimentation, and as the water continues to flow in, the clean water located at the upper layer of the stilling pool 25 flows out of the purification component 2 through the water outlet 2102, and flows into the entrance chamber 1102 for temporary storage.

[0047] At the same time, a sewage outlet 22 is provided at the bottom of the static pool 25, one end of which passes through the purification box 21 and can be connected to the outside world, and the sewage outlet 22 is always in a closed state. When it is necessary to clean the bottom of the static pool 25, the sewage outlet 22 is opened to discharge all the water in the static pool 25, and at the same time, the sediment at the bottom of the static pool 25 is cleaned through the sewage outlet 22.

[0048] In order to maintain the oxygen content in the bunker within a safe range at all times and facilitate the direct introduction of purified water into the oxygen production component 5, the oxygen production component 5 includes a carrying box 51, a steam chamber 5103 is provided in the carrying box 51, so that water flows into the steam chamber 5103, and a partition 52 is spirally distributed in the steam chamber 5103. The partition 52 is used to limit the flow path of the water flow and water vapor, and the partition 52 is distributed in a spiral shape, thereby increasing the water flow heating range, and no electric heating wire is provided on the side of the spiral close to the oxygen generator 53, so that the water vapor is condensed to form distilled water when it is close to the oxygen generator 53, wherein the partition 5 2 is fixedly provided with an electric heating wire, which is in full contact with the water in the steam chamber 5103. An oxygen generator 53 for electrolyzing water molecules is fixedly provided in the middle position of the carrying box 51, wherein only steam can pass between the steam chamber 5103 and the oxygen generator 53, thereby ensuring that the purified water will not enter the oxygen generator 53 through the steam chamber 5103 and cause damage to the oxygen generator 53. The purified water in the steam chamber 5103 is heated to boiling by the electric heating wire, so that the water vapor flows into the vicinity of the oxygen generator 53 to form distilled water, and then the distilled water is electrolyzed by the oxygen generator 53 to form oxygen to replenish the bunker.

[0049] A connecting hole 5101 and an air outlet 5102 are respectively provided on the carrying box 51. One end of the connecting hole 5101 is connected to the flow chamber 1201, and a closing plate is slidably provided between the connecting hole 5101 and the flow chamber 1201. The movement of the closing plate is controlled by the control component, and the bottom end of the connecting hole 5101 is flush with the bottom wall of the flow chamber 1201, so that the water in the flow chamber 1201 can flow into the connecting hole 5101 conveniently. The other end is connected to the steam chamber 5103. One end of the air outlet 5102 is connected to the exhaust chamber 1202, and the other end is connected to the chamber where the oxygen generator 53 is located, so that the oxygen formed after the electrolysis enters the exhaust chamber 1202 through the air outlet 5102 for storage.

[0050] In order to accelerate the precipitation of impurities in the water, a reagent box 24 for accelerating the precipitation of impurities in the water is fixedly provided in the purification box 21. The reagent box 24 can drip the reagent into the static pool 25. In this embodiment, the main component of the reagent is alum, so that the reagent absorbs and condenses the impurities in the static pool 25, and then the reagent carries the impurities to form flocs and sinks to the bottom of the static pool 25.

[0051] In order to prevent the flocs that have not been completely precipitated in the static tank 25 from entering the flow chamber 1201 with the water flow and affecting the purification purity of the purified water, a filter layer 23 is fixedly provided in the flow chamber 1201. The floc impurities in the water are absorbed and filtered by the filter layer 23. The filter layer 23 is located on the side of the oxygen production component 5 close to the inlet end 11, so that the purified water passing through the purification component 2 first passes through the filter layer 23 before entering the flow chamber 1201.

[0052] In order to facilitate the transmission of oxygen into the bunker and ensure that water molecules are fully decomposed in the oxygen generator 53, the air supply component 4 includes a restriction ring 41, which is connected to the flow end 12. A fan 42 is connected inside the restriction ring 41, and the rotation speed of the fan 42 is regulated by the control component. One end of the restriction ring 41 is connected to the exhaust chamber 1202, and the other end is connected to the space in the bunker.

[0053] Initially, the baffle plate located at the outflow port 3 completely closes the outflow port 3, the closing plate of the connecting hole 5101 completely closes the connecting hole 5101, and the electric heating wire does not perform heating work.

[0054] When working, the unpurified water flows into the inlet chamber 1102 after passing through the filter plate 1101, and the external water is initially filtered by the filter plate 1101, and then the water flows into the water inlet 2101 through the inlet chamber 1102 and enters the connecting chamber 26. The separation plate on the connecting chamber 26 further filters the impurities in the water, and when the connecting chamber 26 passes through the separation plate, the control component starts to work, detects the flow rate and flow volume of the water passing through the separation plate, and records the data through the control component, and uploads the data recorded by the control component to the control center of the bunker, so that The user can more intuitively understand the amount of purified water, which is convenient for the reasonable distribution of water in the bunker. Then the water in the connecting cavity 26 flows into the static pool 25 after passing through the separation plate, and then is statically processed. It should be noted that when the water flows into the static pool 25, it will not cause a large fluctuation on the water surface of the static pool 25. When the water level in the static pool 25 accumulates to half of the total water volume in the pool, that is, when the pressure at the bottom of the static pool 25 is sufficient, the control component regulates the reagent box 24 to start working, and the reagent in the reagent box 24 is dripped until the reagent flows into the static pool 25, thereby removing impurities in the water of the static pool 25. Adsorption and precipitation are performed to improve the purification rate. In order to ensure that the reagent in the static pool 25 will not be wasted, the reagent inflow rate in the reagent box 24 is controlled by the control component to monitor the water flow rate through the separation plate. At the same time, the static pool 25 flows the purified water on the upper layer into the water outlet 2102 by overflowing, thereby moving out of the purification box 21 and entering the flow chamber 1201. At the same time, when the water in the static pool 25 is always overflowing, and as the sediment in the static pool 25 gradually increases, the water level depth of the static pool 25 decreases, and the pressure at the bottom of the static pool 25 increases, and then when the static pool 25 is After the pressure at the bottom of 25 increases to the set value (set according to the size of the pool), the cleaning instruction is uploaded to the control center of the bunker through the control component, so that the staff suspends the flow of water into the cavity 1102, and then opens the sewage outlet 22 to clean the sediment at the bottom of the static pool 25, maintain the water depth of the static pool 25, and maintain a sufficient water depth. At the same time, when the water flows through the outlet 2102, in order to further filter the odor and possible flocs in the water, the water flows through the filter layer 23 for further purification, and the purified water flows to the bottom of the flow cavity 1201.

[0055] There are three types of treatment for purified water, and the control center in the bunker regulates and distributes the purified water:

[0056] When the oxygen in the bunker is within a safe range, the baffle is controlled to move and the position of the closing plate is maintained unchanged, so that all the purified water enters the bunker's water circulation system through the outflow port 3; when the oxygen in the bunker is at a critical value within a safe range, the baffle and the closing plate are controlled to move simultaneously, and the positions of the baffle and the closing plate are in a half-open state, so as to achieve uniform distribution of purified water, so that one part flows into the purification component 2, and the other part flows into the bunker's water circulation system through the outflow port 3; when the oxygen in the bunker is within a dangerous range, and the water circulation system in the bunker is sufficient to support the bunker's daily water consumption, the baffle position is maintained unchanged by the control component, the position of the closing plate is fully opened, and all the purified water is introduced into the purification component 2.

[0057] When the closing plate is opened, the electric heating wire is adjusted to work through the control component, and the water flowing into the cavity 1201 enters the carrying box 51 through the connecting hole 5101. At the same time, the heating power of the electric heating wire is controlled by the movement degree of the closing plate. When the closing plate is in a closed state, the electric heating wire does not work. When the closing plate is in a half-open state, the heating rate of the electric heating wire is in an intermediate state. When the closing plate is fully opened, the heating rate of the electric heating wire is in a high-efficiency operation state, that is, the heating rate at this time is the fastest. When the water flows into the carrying box 51 and flows into the steam chamber 5103, the purified water contacts the electric heating wire and heats the purified water to form a steam state and move in the steam chamber 5103, thereby allowing the steam to pass through the partition 5 2 enters the chamber of the oxygen generator 53, and condenses in the chamber of the oxygen generator 53 to form distilled water. After the distilled water is decomposed into oxygen by the oxygen generator 53, the oxygen enters the exhaust chamber 1202 through the air outlet 5102. At the same time, the more distilled water there is, the faster the oxygen generator 53 produces oxygen. Then, the control component controls the fan 42 to work, and the oxygen in the exhaust chamber 1202 enters the bunker through the fan 42 and the restriction ring 41 to replenish the oxygen in the bunker. The rotation speed of the fan 42 is controlled by the oxygen production rate of the oxygen generator 53, that is, as the oxygen production rate of the oxygen generator 53 increases, the rotation speed of the fan 42 becomes faster, thereby avoiding the accumulation of oxygen in the exhaust chamber 1202.
