Description

Technical Field

[0001] The invention belongs to the technical field of safes, in particular to a fireproof safe with an automatic alarm function. Background Art

[0002] Safes are mainly divided into fireproof safes and anti-theft safes, anti-magnetic safes, fireproof anti-magnetic safes and fireproof anti-theft safes. Fireproof file cabinets refer to "paper fireproof file cabinets". The international standard stipulates that in a fire scene of 1000 degrees Celsius, the temperature inside the cabinet must be kept below 180 degrees Celsius for at least one hour to prevent the paper from carbonizing and the handwriting from being clearly legible.

[0003] At present, since safes usually contain important documents or valuables, their fireproof performance plays an important role in the safety of the stored items. However, existing safes only protect the documents inside the safe by blocking the heat conducted to the safe with a single or multi-layer fireproof and heat-insulating material. Especially when the external fire lasts for a long time and spreads rapidly, it is difficult for current fireproof safes to control the temperature below 180 degrees for at least one hour, resulting in the burning or carbonization of the paper inside the safe, which is not conducive to protecting the items stored in the safe. Summary of the Invention

[0004] In order to make up for the shortcomings of the existing technology and solve the problem that when the existing safe is in the face of a long fire and the fire spreads rapidly, it is difficult to keep the temperature inside the cabinet below 180 degrees for at least one hour, which leads to the destruction of the items stored inside the safe, the present invention proposes a fireproof safe with an automatic alarm function.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a fireproof safe with automatic alarm function described in the present invention comprises:

[0006] An outer shell, with an outer cabinet door hingedly connected to the outer shell;

[0007] An inner shell, the inner shell being placed inside the outer shell, and an inner cabinet door being hingedly connected to the inner shell;

[0008] The safe further comprises:

[0009] a first partition plate, which is installed between the outer shell and the inner shell and has an open end;

[0010] a second partition plate, the second partition plate being installed between the first partition plate and the inner shell and having an open end;

[0011] a connecting post, the connecting post being fixedly connected to the bottom of the inner shell and the other end being fixedly connected to the upper surface of the second partition;

[0012] a first cover plate, the first cover plate being fixedly connected to the outer shell and the first partition plate to form a receiving cavity, the receiving cavity being filled with yellow mud and a hot-melt water bag, and the hot-melt water bag being filled with water;

[0013] A rubber strip is fixedly connected to the first separator and the second separator to form a sealed cavity filled with a phase change energy storage material.

[0014] Preferably, a second cover plate is fixedly connected to one end of the inner shell and the opening of the second partition plate, and a vacuum chamber is formed by vacuuming the space formed by the inner shell, the second partition plate and the second cover plate.

[0015] Preferably, the phase change energy storage material is phase change paraffin.

[0016] Preferably, the air pressure inside the vacuum chamber is in the range of 0.5-5 Pa.

[0017] Preferably, the distance between the first partition and the second partition is 5-10 cm.

[0018] Preferably, glass fiber yarns are fixedly connected to the outer surface of the hot-melt water bag, and the other ends of the glass fiber yarns are fixedly connected to the surface of the first partition facing the outer shell.

[0019] Preferably, the safe further comprises:

[0020] A displacement unit is installed between the first partition plate and the second partition plate, and the displacement unit is controlled to enable the inner shell to move laterally toward the side with lower temperature inside the outer shell.

[0021] Preferably, the displacement unit includes:

[0022] a memory spring, one end of the memory spring being fixedly connected to a surface of the first partition facing the inner shell, and the other end being mounted on a surface of the second partition facing away from the inner shell, wherein the memory springs are provided in plurality and are evenly arranged along the width and height of the outer shell;

[0023] A roller is rotatably mounted on the lower surface of the second partition.

[0024] Preferably, the deformation degree of the memory spring arranged along the width of the outer shell gradually increases with increasing temperature.

[0025] Preferably, the outer surface of the inner shell is sprayed with a barrier-type thermal insulation coating.

A fireproof safe with an automatic alarm function described in the present invention has a plurality of glass fiber filaments fixedly connected to the outer surface of a hot-melt water bag, and the other ends of the glass fiber filaments are fixedly connected to the surface of a first partition facing the outer shell. This can effectively prevent the hot-melt water bag from moving inside the accommodating cavity before being heated, which would cause the yellow mud in the rest of the accommodating cavity to be unable to effectively mix with water to form a dense mud wall in the event of a fire, thereby causing heat to be conducted to the inner shell through this part, causing local overheating of the inner shell and damage to the documents inside the inner shell.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 3 As shown, the fireproof safe with automatic alarm function of the present invention comprises:

[0036] An outer cabinet body 1, to which an outer cabinet door 2 is hinged;

[0037] An inner housing 3 is placed inside the outer housing 1 and is hinged with an inner cabinet door 4;

[0038] The safe further comprises:

[0039] a first partition plate 5 , which is installed between the outer shell 1 and the inner shell 3 and has an open end;

[0040] A second partition plate 6 is installed between the first partition plate 5 and the inner shell 3 and is open at one end;

[0041] A connecting post 7, wherein the connecting post 7 is fixedly connected to the bottom of the inner shell 3 and the other end is fixedly connected to the upper surface of the second partition 6;

[0042] a first cover plate 8, the first cover plate 8 being fixedly connected to the outer shell 1 and the first partition plate 5 to form a receiving cavity 81, the receiving cavity 81 being filled with yellow mud and a hot-melt water bag 82, and the hot-melt water bag 82 being filled with water;

[0043] A rubber strip 9, the rubber strip 9 being fixedly connected to the first separator 5 and the second separator 6 to form a sealed cavity 91, wherein the sealed cavity 91 is filled with a phase change energy storage material;

[0044] When working, the fireproof safe with automatic alarm function of the present application includes: an outer shell 1, an outer cabinet door 2 is hingedly connected to the outer shell 1 on one side of the opening, an inner shell 3 is placed inside the outer shell 1, an inner cabinet door 4 is hingedly connected to the inner shell 3, a first partition 5 is installed between the outer shell 1 and the inner shell 3, one end of the first partition 5 is open, and the opening between the first partition 5 and the outer shell 1 is connected by a first cover 8, thereby forming a sealed accommodating chamber 81, the accommodating chamber 81 is filled with yellow mud and hot-melt water bags 82 evenly arranged in the accommodating chamber 81, the yellow mud is powdery, and the hot-melt water bags 82 are uniformly arranged in the accommodating chamber 81. The hot-melt water bag 82 is made of either plastic or rubber and is extremely thin. Water is filled in the hot-melt water bag 82. A second partition 6 is installed between the first partition 5 and the inner shell 3. A connecting column 7 is fixedly connected to the bottom of the inner shell 3. The other end of the connecting column 7 is fixedly connected to the upper surface of the second partition 6. The second partition 6 and the first partition 5 are sealed by a rubber strip 9 to form a sealed cavity 91. The connection is tightly connected with high-temperature resistant glue. The sealed cavity 91 is filled with phase change energy storage material. A temperature sensor is provided on the inner wall of the outer shell 1. The data measured by the temperature sensor is sent to the terminal platform for early warning.

[0045] Phase change energy storage materials are a type of energy storage material that uses physical phase changes at a specific temperature to achieve energy storage and release. They generally have three forms: solid-liquid, liquid-gas, and solid-solid phase changes. Currently, solid-liquid phase change energy storage materials are the most widely studied and applied. Their working principle is: when the ambient temperature is higher than the phase change temperature, the material changes from solid to liquid and absorbs heat; when the ambient temperature is lower than the phase change point, the material changes from liquid to solid and releases heat, thereby maintaining the ambient temperature at a suitable level. The amount of heat absorbed or released by the material during the phase change process is dozens or even hundreds of times the amount of heat absorbed or released when the temperature of a single phase of the material changes;

[0046] When a fire occurs, the outer shell 1 is burned by the flame and the temperature rises. When the temperature sensed by the temperature sensor installed inside the outer shell 1 exceeds a predetermined threshold, the measured data is sent to the terminal platform for early warning. The terminal platform is a mobile phone APP or a computer receiving platform. The hot-melt water bag 82 in the accommodating cavity 81 formed between the outer shell 1, the first partition 5 and the first cover plate 8 is ruptured by heat, and the water in the hot-melt water bag 82 flows out and mixes with the yellow mud. Because the yellow mud and water have a certain viscosity after mixing, the yellow mud and water are mixed and dried to form a dense fireproof and heat-insulating earth wall, which can effectively prevent the heat on the outer shell 1 from being conducted to the inner shell 3. When the yellow mud and water are mixed, the water continues to evaporate on the inner wall of the outer shell 1, further reducing the temperature on the outer shell 1. At the same time, after the outer shell 1 melts, the flame retardant properties of the dense yellow mud wall effectively ensure that after the outer shell 1 is ruptured, the fire will not cause damage to the inside of the safe, thereby improving the fire safety of the safe of this application.

[0047] As the temperature is conducted to between the first partition 5 and the second partition 6 through the yellow mud wall formed in the accommodating chamber 81, the sealed chamber 91 is filled with phase change energy storage material, which can effectively absorb the heat conducted into the sealed chamber 91, further reducing the heat conducted to the inner shell 3. In the case of severe fire, the time for storing items inside the inner shell 3 can be extended, and the documents and other items placed inside the inner shell 3 can be protected. It has certain practicality and market prospects.

[0048] As an embodiment of the present invention, a second cover plate 11 is fixedly connected to one end of the inner shell 3 and the opening of the second partition plate 6, and a vacuum chamber 12 is formed by vacuuming the space formed by the inner shell 3, the second partition plate 6, and the second cover plate 11;

[0049] During operation, the inner shell 3 and one end of the second partition 6 are fixedly connected with the second cover plate 11, and the space formed by the inner shell 3, the second partition 6 and the second cover plate 11 is evacuated by a vacuum pump, thereby forming a vacuum chamber 12 in the above space. Since the vacuum chamber 12 can reduce the conduction of heat to a certain extent, the heat conducted to the inner shell 3 through the second partition 6 can be reduced by setting the above vacuum chamber 12, and the temperature on the inner shell 3 can be further reduced, so that the temperature inside the inner shell 3 is less than 180 degrees Celsius, which meets the national standards and has certain practical performance.

[0050] As an embodiment of the present invention, the phase change energy storage material is phase change paraffin;

[0051] During operation, the phase change energy storage material filled in the sealed cavity 91 is phase change paraffin powder, which is ET series phase change material, specifically ET92, with a phase change temperature of 92 degrees Celsius.

[0052] During a fire, after a dense earth wall is formed inside the accommodating chamber 81, the heat on the first partition 5 is conducted to the sealed chamber 91, and the phase-change paraffin powder absorbs heat and changes from solid to liquid. Since the phase-change paraffin needs to absorb a large amount of heat when changing from solid to liquid, and it has the characteristic of dissipating heat at a constant temperature, it effectively reduces the heat conducted to the inner shell 3 through the sealed chamber 91, thereby improving the safety of the safe of the present application for documents or other items stored inside the inner shell 3, and has certain practicality.

[0053] As an embodiment of the present invention, the air pressure inside the vacuum chamber 12 is in the range of 0.5-5 Pa;

[0054] During operation, the vacuum chamber 12 is controlled within the medium vacuum range by a vacuum pump, with a range of 0.5-1 Pa, to control the heat conduction of the gas and limit the movement of gas molecules, thereby reducing the heat conduction to the inner shell 3 and reducing the temperature inside the inner shell 3;

[0055] According to the needs, the types of items to be stored can be selected, and safes with different vacuum gradients can be selected. When it is necessary to ensure that the temperature inside the inner shell 3 is low, for example, when CDs, memory cards, and bank cards need to be stored, a safe with a vacuum chamber 12 of about 0.5 Pa can be selected to ensure that the temperature of the inner shell 3 is low, and to avoid damage caused by excessively high temperature inside the inner shell 3 of the safe of this application in the event of a fire; when it is necessary to store paper documents, since the ignition point of paper is 130-180 degrees Celsius, a safe with an air pressure of about 5 Pa in the vacuum chamber 12 can be selected, so as to effectively ensure that the paper is not damaged while reducing the purchaser's expenditure, and has certain practicality and market prospects.

[0056] As an embodiment of the present invention, the distance between the first partition 5 and the second partition 6 is 5-10 cm;

[0057] During operation, by setting the distance between the first partition 5 and the second partition 6 to be 5-10 cm, the phase change paraffin powder in the sealed cavity 91 can effectively improve the absorption of heat conducted to the inside of the sealed cavity 91, which can meet the customer's needs for storing different documents or items;

[0058] When the distance between the first partitions 5 is 5 cm, the phase-change paraffin powder inside the sealed cavity 91 can continuously absorb the heat conducted into the sealed cavity 91 through the first partition 5, thereby effectively ensuring that the temperature inside the inner shell 3 is lower than the 180 degrees Celsius requirement specified by the national standard. If the purchaser requires the storage of items with a low melting point or ignition point, a safe with a farther distance between the first partition 5 and the second partition 6 can be selected to meet customer needs and has certain practicality.

[0059] As an embodiment of the present invention, the outer surface of the hot-melt water bag 82 is fixedly connected with a glass fiber filament 83, and the other end of the glass fiber filament 83 is fixedly connected to the surface of the first partition 5 facing the outer shell 1;

[0060] During operation, by fixing a plurality of glass fiber yarns 83 on the outer surface of the hot-melt water bag, and fixing the other end of the glass fiber yarns 83 on the surface of the first partition plate 5 facing the outer shell 1, the hot-melt water bag 82 can be effectively prevented from moving inside the accommodating cavity 81 before being heated, which causes the hot-melt water bag 82 to pile up together in the event of a fire, and the yellow mud in the rest of the accommodating cavity 81 cannot be effectively mixed with the water, thereby causing heat to be conducted to the inner shell 3 through this place, causing the inner shell 3 to locally overheat and the documents inside the inner shell 3 to be damaged. Moreover, since the melting point of the glass fiber yarns 83 is 300-500 degrees Celsius, the glass fiber yarns 83 may melt only after the hot-melt water bag 82 breaks, thereby ensuring that the position of the hot-melt water bag 82 inside the accommodating cavity 81 is in a stable state, thereby improving the effectiveness of the fire protection of the safe of this application.

[0061] As an embodiment of the present invention, the safe further includes:

[0062] a displacement unit, the displacement unit being installed between the first baffle 5 and the second baffle 6, and controlling the displacement unit to enable the inner shell 3 to move laterally toward the side with a lower temperature inside the outer shell 1;

[0063] The displacement unit comprises:

[0064] A memory spring 13, one end of which is fixedly connected to the surface of the first partition 5 facing the inner shell 3, and the other end is mounted on the surface of the second partition 6 facing away from the inner shell 3. There are multiple memory springs 13 and they are evenly arranged along the width and height of the outer shell 1;

[0065] A roller 14, the roller 14 being rotatably mounted on the lower surface of the second partition 6;

[0066] When in operation, the safe of the present application further includes: a displacement unit, which is installed between the first partition 5 and the second partition 6. When a fire occurs, there are fire points distributed at different positions of the safe, resulting in different temperatures on the outer surface of the safe. After the heat is transferred to the inner shell 3, the inner shell 3 is locally overheated, which in turn causes damage to the documents or items stored inside the inner shell 3. The present application provides a displacement unit to achieve the effect of moving the inner shell 3 laterally toward the side with lower temperature in the safe to reduce the temperature transferred to the inner shell 3, thereby protecting the documents or items inside the inner shell 3, which has certain practicality.

[0067] The displacement unit includes a memory spring 13, one end of which is fixedly connected to the surface of the first partition 5 facing the inner shell 3, and the other end of which is movably mounted on the surface of the second partition 6 facing away from the inner shell 3, i.e., not fixedly connected to this surface. There are multiple memory springs 13 and they are evenly arranged along the width and height of the outer shell 1. A roller 14 is mounted on the lower surface of the second shell.

[0068] When a fire occurs, when the fire source is relatively on the left side of the safe, the heat of the fire source relatively on the left side of the safe is conducted to the left side of the outer shell 1. The temperature on the right side of the outer shell 1 is lower than the temperature on the left side of the outer shell 1. After the heat on the left side of the outer shell 1 is conducted to the sealed cavity 91, the heat is absorbed by the phase-change paraffin powder inside the sealed cavity 91. The phase-change paraffin powder on the left side of the sealed cavity 91 becomes liquid. At the same time, the memory spring 13 made of Ti-Ni alloy reaches the deformation temperature. Therefore, under the action of the memory spring 13, the memory spring 13 pushes the second partition 6 to move toward the opposite side, so that the inner shell 3 is away from the side closer to the fire source inside the outer shell 1, thereby reducing the heat conducted to the inner shell 3 through the outer shell 1, effectively ensuring the safety of the documents inside the inner shell 3, and having certain practical performance. In the memory spring 13 While pushing the second partition 6 toward the opposite side, the phase-change paraffin wax powder in the space on the right side of the sealed cavity 91 is in a solid-liquid coexistence state due to its melting point of 92 degrees. At this time, the opposite side surface (right side surface) of the second partition 6 squeezes the solid-liquid coexistence phase-change paraffin wax in the space on the right side of the sealed cavity 91, so that the solid-liquid coexistence paraffin wax on the right side of the sealed cavity 91 is exchanged with the liquid phase-change paraffin wax on the left side of the sealed cavity 91. When the solid-liquid coexistence phase-change paraffin wax moves to the left side of the sealed cavity 91, this part of the phase-change paraffin wax can continue to absorb the heat conducted to the sealed cavity 91 through the left side of the safe, effectively improving the use effect of the present application, having certain practicality, ensuring that the temperature inside the inner shell 3 is lower than the ignition point of the paper inside the inner shell 3, extending the time for the safe to store items in a fire, and ensuring the use effect of the safe of the present application.

[0069] As an embodiment of the present invention, the deformation degree of the memory spring 13 arranged along the width of the outer shell 1 gradually increases as the temperature rises;

[0070] During operation, the deformation degree of the memory spring 13 along the width direction of the outer shell gradually increases as the temperature rises, and the end of the memory spring 13 close to the outer surface of the second partition 6 is not fixedly connected to the outer surface of the second partition 6, so that the deformation length of the memory metal gradually increases as the temperature rises. Subsequently, when the fire on one side of the safe is large, the distance between the inner shell 3 and the fire source can be increased, thereby reducing the heat conducted to the inner shell 3, ensuring the safety of the paper documents inside the inner shell 3, and having a certain degree of safety.

[0071] As an embodiment of the present invention, the outer surface of the inner shell 3 is sprayed with a barrier type thermal insulation coating;

[0072] During operation, a barrier-type thermal insulation coating is sprayed on the outer surface of the inner shell 3. Since the thermal conductivity of the coating is very small after drying and forming a film, the coating has a certain ability to slow down the transfer of heat flow, thereby effectively reducing the heat conducted from the second partition 6 to the inner shell 3 through the vacuum chamber 12, ensuring that the internal temperature of the inner shell 3 is not higher than the specified threshold, effectively ensuring the safety of paper documents inside the inner shell 3, and having certain market prospects.

[0073] The specific implementation process is as follows:

[0074] When a fire occurs, the outer shell 1 is burned by the flame and the temperature rises. When the temperature sensed by the temperature sensor installed inside the outer shell 1 exceeds a predetermined threshold, the measured data is sent to the terminal platform for early warning. The terminal platform is a mobile phone APP or a computer receiving platform. The hot-melt water bag 82 in the accommodating cavity 81 formed between the outer shell 1, the first partition 5 and the first cover plate 8 is ruptured by heat, and the water in the hot-melt water bag 82 flows out and mixes with the yellow mud. After the yellow mud and water are mixed and dried, a dense fireproof and heat-insulating wall is formed, which effectively blocks the heat on the outer shell 1 from being conducted to the inner shell 3. When the yellow mud and water are mixed, the water evaporates continuously on the inner wall of the outer shell 1, further reducing the temperature on the outer shell 1. At the same time, after the outer shell 1 melts, the flame retardant properties of the dense yellow mud wall can also effectively ensure the fire safety of the safe of this application.

[0075] The heat on the first partition 5 is conducted to the sealed cavity 91, and the phase change paraffin powder absorbs heat and changes from solid to liquid. Since the phase change paraffin needs to absorb a large amount of heat when changing from solid to liquid, and it has the characteristic of dissipating heat at a constant temperature, it effectively reduces the heat conducted to the inner shell 3 through the sealed cavity 91, thereby improving the safety of the safe of this application for documents or other items stored inside the inner shell 3.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
