[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Reference Figures 1 to 3 Now, the assembled fire wall and device for the power supply station provided by the present invention are described.

[0030] An assembled fire wall for a power supply station, the fire wall comprising a plurality of prefabricated walls; the prefabricated wall comprising: a wall body 1, a structural layer 2 fixedly connected to one side of the wall body 1, and a fire extinguishing unit; a release groove 21 is provided on the structural layer 2; the fire extinguishing unit is fixedly connected in the release groove 21;

[0031] The fire extinguishing unit includes: a storage capsule 3 and a release mechanism 4 arranged in a release groove 21; fire extinguishing substances are stored in the storage capsule 3, the storage capsule 3 has a high pressure inside, a fragile glass is fixedly connected to one side of the storage capsule 3 close to the opening of the release groove 21, and the release mechanism 4 is arranged at the opening of the release groove 21; when a fire occurs, the release mechanism 4 breaks the fragile glass and releases the storage capsule 3; the storage capsule 3 releases the fire extinguishing substances toward the fire source through the opening of the release groove 21.

[0032] The assembled fire wall for power supply station provided by the present invention has the following beneficial effects: Compared with the prior art, in the assembled fire wall for power supply station of the present invention, the storage capsule 3 is in a high pressure state and contains fire extinguishing substances. When a fire occurs, the storage capsule 3 can quickly break the fragile glass with the help of the release mechanism 4, thereby releasing the fire extinguishing substances. This process can quickly and effectively extinguish the source of the fire, play a role in extinguishing the fire, and effectively curb the spread of the fire. The fire extinguishing substances are stored in advance and released immediately when the fire occurs. Compared with the traditional fire extinguishing method, this method is more timely and efficient, and can effectively control the fire in the early stage, thereby reducing the losses caused by the fire.

[0033] Prefabricated walls are usually made of a variety of materials, the most common of which are concrete, lightweight panels, etc. In terms of technology, factory production may be used to accurately control the size, shape and quality of the wall to ensure the accuracy and consistency of each component. For example, prefabricated concrete parts are cast in molds, or lightweight panels are finely processed. In terms of assembly methods, prefabricated walls are generally transported to the construction site using special lifting equipment and assembled through precise positioning and connection methods. Common connection methods include mortise and tenon connections and mechanical connections (such as bolts, welding, etc.), which can ensure a firm connection between walls and improve the overall stability of the building.

[0034] Compared with traditional construction methods, the use of prefabricated walls has the following advantages: fast construction speed, reducing on-site construction time, which is conducive to shortening the construction period of the entire construction project. Controllable quality, the quality of the wall can be better guaranteed in the factory production environment, and the quality problems caused by on-site construction can be reduced. Energy saving and environmental protection, the factory production process can better control the use of materials and waste emissions, while reducing noise and dust pollution on the construction site. It has good thermal insulation, heat insulation and sound insulation performance, which can effectively improve the energy efficiency and living comfort of the building.

[0035] In a preferred embodiment, the fire extinguishing substance stored in the storage capsule 3 is sodium bicarbonate powder. When extinguishing a fire, sodium bicarbonate decomposes under heat to produce carbon dioxide gas and water. Carbon dioxide acts to isolate the air and isolate the burning material from oxygen; water can absorb heat and reduce the temperature of the burning material, thereby achieving the purpose of extinguishing the fire. The advantages of using sodium bicarbonate powder as a fire extinguishing substance are: the fire extinguishing speed is fast, the application range is wide, and it can extinguish general solid material fires, flammable liquid fires, and electrical equipment fires. In addition, dry powder fire extinguishing agents are easy to store and transport, and the cost is relatively low.

[0036] In a preferred embodiment, the fire extinguishing substance stored in the storage capsule 3 is liquid carbon dioxide. When extinguishing a fire, the liquid carbon dioxide is quickly vaporized after being ejected from the storage capsule 3, absorbing a large amount of heat, causing the temperature around the burning object to drop rapidly; at the same time, the density of carbon dioxide is greater than that of air, and it will cover the surface of the burning object, isolating the air, thereby preventing the combustion from continuing. The advantage of using liquid carbon dioxide as a fire extinguishing substance is that it leaves no traces after extinguishing the fire, and does not cause pollution to the objects being extinguished. It is particularly suitable for extinguishing fires of precision instruments, books and archives. Moreover, carbon dioxide itself does not participate in the combustion process and does not damage electrical equipment.

[0037] The storage capsule 3 is specifically a high-pressure tank made of alloy steel, which is filled with high-pressure gas and fire extinguishing substances. The high-pressure gas stored in the storage capsule 3 is nitrogen, and the opening of the storage capsule 3 is sealed with fragile glass. After the fragile glass at the opening of the storage capsule 3 is broken, the high-pressure gas in the storage capsule 3 is ejected, and the fire extinguishing substances inside it are blown out at the same time.

[0038] Fragile glass is usually made of materials such as borosilicate glass. Its main function is to provide warnings or prevent accidental collisions in certain situations. For example, in some places that require special attention, such as the casing of electrical equipment, fragile glass can be broken when hit by a large external force to attract people's attention and avoid more serious consequences.

[0039] Fragile glass has a wide range of applications. For example, the protective glass of some instruments and meters can break under a certain external force when an abnormal situation occurs in the internal instruments and people need to detect it in time. In some display cabinets, fragile glass is used to prevent theft, etc. Once it is damaged, it will make a sound. Some car warning light glass also uses fragile glass to serve as a warning under certain conditions.

[0040] In a possible implementation, the release mechanism 4 includes:

[0041] The hammer 41 is slidably connected in the release slot 21; the hammer 41 is provided with a slot 411;

[0042] The energy storage member 42 is fixedly connected in the release slot 21; the energy storage member 42 is used to drive the hammer 41 to slide and break the fragile glass; and

[0043] The release component 43 is inserted in the card slot 411; a mounting slot 22 is provided in the structural layer 2, and the release component 43 is arranged in the mounting slot 22; when a fire occurs, the release component 43 is deformed and slides out of the card slot 411 to release the hammer 41.

[0044] In a preferred embodiment, the energy storage component is a spring. When no fire occurs, the release component 43 is inserted into the slot 411 to limit the position of the hammer 41. At this time, the energy storage component is in a compressed state. When a fire occurs, the release component 43 slides out of the slot 411, releasing the limit of the hammer 41, and the energy storage component releases energy, driving the hammer 41 to slide toward the fragile glass, breaking the fragile glass, thereby releasing the fire extinguishing substance in the storage capsule 3.

[0045] In a preferred real-time mode, the energy storage component is two magnets with the same poles facing each other, and the hammer 41 is driven to slide by the principle that the same poles of magnets repel each other. When there is no fire, the release component 43 is inserted in the slot 411 to limit the position of the hammer 41. At this time, the energy storage component is in a compressed state. When a fire occurs, the release component 43 slides out of the slot 411, releasing the limit of the hammer 41, and the energy storage component releases energy, driving the hammer 41 to slide towards the fragile glass, breaking the fragile glass, thereby releasing the fire extinguishing substance in the storage capsule 3.

[0046] In a preferred embodiment, an injection channel is provided on the hammer 41. After breaking the fragile glass, the hammer 41 collides with the opening of the storage capsule 3 under the action of the energy storage component and blocks the opening of the storage capsule 3. The high-pressure gas and fire extinguishing substance in the storage capsule 3 are ejected from the injection channel on the hammer 41.

[0047] In a possible implementation, the release component 43 includes:

[0048] The hook 431 is slidably connected in the slot 411;

[0049] The deformable member 432 is disposed in the mounting groove 22 ; one end of the deformable member 432 is connected to the hook 431 , and the other end is out of the mounting groove 22 and exposed to the outside of the structural layer 2 .

[0050] The portion of the deformable member 432 away from the hook 431 is fixedly connected to the mounting groove 22, and the remaining portion is not fixedly connected to the inner wall of the mounting groove 22. When a fire occurs, the temperature of the surrounding environment rises, and when the deformable member 432 is heated, it will deform, and use its own deformation to drive the hook 431 to slide out of the slot 411, thereby releasing the limit of the hammer 41.

[0051] In a possible implementation, the deformable member 432 is made of memory metal, and deforms when heated, and drives the hook 431 to slide out of the slot 411. When the deformable member 432 is at a low temperature, the deformable member 432 is a horizontal straight rod, and the hook 431 is inserted in the slot 411. When the temperature is high, the deformable member 432 returns to a bent rod, and the deformable member 432 drives the hook 431 to slide out of the slot 411.

[0052] The material of memory metal is nickel-titanium alloy. It has the following characteristics: shape memory effect, can return to the preset shape at a specific temperature; good elasticity and flexibility, can withstand repeated deformation without damage; strong corrosion resistance.

[0053] The application scenarios of memory metals are: in the field of medical devices, such as orthopedic internal fixation equipment, which can be restored to a suitable shape according to the physiological environment of the human body after being implanted in the human body, fix the fracture site, and then can be removed under specific conditions. In the field of aerospace, it is used to manufacture components such as satellite antennas, which can be folded to save space during launch and can be restored to their original state after reaching orbit to start working. In the automotive industry, such as the manufacture of valves and other parts of automobile engines, they can maintain good performance under different working conditions. In daily life, some glasses frames are made of memory metal, which are more comfortable to wear and not easy to deform.

[0054] In a possible implementation, the deformable member 432 includes a first metal sheet 433 and a second metal sheet 434 that are fixedly connected, and the first metal sheet 433 and the second metal sheet 434 have different thermal expansion coefficients; the deformable member 432 deforms after being heated and drives the hook 431 to slide out of the slot 411.

[0055] The first metal sheet 433 is made of copper, and the second metal sheet 434 is made of aluminum. The first metal sheet 433 is arranged on the side close to the hammer 41, and the second metal sheet 434 is arranged on the side away from the hammer 41. At low temperatures, the deformable member 432 is a horizontal straight rod, and the hook 431 is inserted into the slot 411. At high temperatures, the expansion degree of the first metal sheet 433 is greater than that of the second metal sheet 434, so that the deformable member 432 becomes bent, driving the hook 431 to slide out of the slot 411, and releasing the limited state of the hammer 41.

[0056] The deformation member 432 made of two metal materials with different thermal expansion coefficients has the following characteristics:

[0057] First, when the temperature changes, due to the difference in thermal expansion coefficients of the two metals, relative elongation or contraction will occur, thereby causing the deformation member 432 to deform. This deformation includes linear, bending or other specific shape changes.

[0058] Secondly, by selecting the right two metal materials, the degree and direction of deformation can be precisely controlled to meet specific engineering requirements.

[0059] Furthermore, it has high sensitivity and response speed, and can respond quickly to tiny temperature changes.

[0060] The deformable member 432 made of two metal materials with different thermal expansion coefficients has the following application scenarios:

[0061] In terms of temperature sensors, the difference in thermal expansion and contraction of two metal materials is used to measure temperature changes. For example, a bimetallic thermometer is based on this principle, and the bending degree of the deformable member 432 indicates the temperature.

[0062] In terms of the temperature control switch, in some temperature control systems, the deformable member 432 can act as a trigger element of the switch. When the temperature reaches the set value, the deformable member 432 deforms, triggering the switch action, thereby achieving temperature control.

[0063] In terms of precision instruments, for some instruments with high precision requirements, the deformable member 432 made of metal materials with different thermal expansion coefficients can be used to adjust the structure or position of the instrument to ensure the accuracy and stability of the instrument.

[0064] In the aerospace field, in some high temperature environments (such as engine compartments, etc.), the deformable part 432 made of metal materials with different thermal expansion coefficients can be used to compensate for structural deformation caused by temperature changes to ensure the normal operation of the equipment.

[0065] In a possible implementation, the structural layer 2 is a gypsum board.

[0066] As a fireproof material, gypsum board has the following characteristics:

[0067] First, it has good fire resistance. Gypsum itself has fire resistance. When it encounters fire, it will dehydrate and decompose. This process will absorb heat and thus prevent the spread of fire.

[0068] Second, it is lightweight. Its low density makes it easy to install and construct, and helps reduce the weight of the building.

[0069] Third, it has sound insulation function. It has a certain sound insulation effect and can reduce the spread of noise.

[0070] As a fireproof material, gypsum board is mainly used in the following scenarios:

[0071] In terms of building partitions, it is often used for internal partitions of buildings, which can isolate the spread of fire and smoke to a certain extent, and buy time for personnel evacuation and fire rescue.

[0072] In terms of suspended ceilings, it can be used as a suspended ceiling material. Once a fire occurs, it can slow down the spread of the fire upwards, thereby protecting the superstructure and personnel safety.

[0073] In special fire protection areas, such as computer rooms, distribution rooms and other places with high fire protection requirements, gypsum board can play a role in fire isolation.

[0074] In a possible implementation, a fireproof layer 5 is provided between the structural layer 2 and the wall body 1 .

[0075] In a preferred embodiment, the material of the fireproof layer 5 is glass wool. Glass wool is made of glass fiber and is widely used in the walls and roofs of buildings because of its good heat insulation and fireproof properties.

[0076] In a preferred embodiment, the material of the fireproof layer 5 is rock wool. Rock wool is an inorganic fiber material made from melted basalt, which has a high temperature resistance of 600-1000 degrees Celsius and is widely used in heat insulation and fire protection of buildings and industrial equipment.

[0077] In a preferred embodiment, the fireproof layer 5 is a fireproof board. The fireproof board is made of silicate and fiber-reinforced materials, processed under high temperature and high pressure, has excellent fireproof and heat insulation properties, and is commonly used in the design of fireproof doors, partition walls and fireproof ceilings.

[0078] In a preferred embodiment, the material of the fireproof layer 5 is expanded perlite. Expanded perlite is a natural volcanic mineral that expands at high temperatures to form a lightweight material. This material has good fireproof and heat-insulating properties and is often used for fireproof and heat-insulating filling of buildings.

[0079] In a preferred embodiment, the material of the fireproof layer 5 is foam glass. Foam glass is a porous material sintered from glass powder, which has excellent fireproof and heat-insulating properties, as well as waterproof and anti-corrosion properties.

[0080] In a preferred embodiment, the fireproof layer 5 is made of foamed glass aluminum silicate fiber. Foamed glass aluminum silicate fiber is a lightweight refractory material with excellent high temperature resistance and is often used in the insulation of industrial furnaces, pipelines and high temperature equipment.

[0081] In a preferred embodiment, the fireproof layer 5 is made of an inorganic fiber spray material, which is a fireproof and heat-insulating material that is easy to construct and is composed of inorganic fibers and a binder, and can be directly sprayed on the surface of a building structure to form a fireproof and heat-insulating layer.

[0082] In a possible implementation, a connection groove 11 is provided on one side of the wall body 1 , and a connection block 12 is provided on the other side; adjacent prefabricated walls are connected by means of the connection groove 11 and the connection block 12 .

[0083] In a possible implementation, it further includes a connection mechanism 6 for connecting adjacent prefabricated walls; a connection hole is opened on the wall body 1, and the connection mechanism 6 is arranged in the connection hole.

[0084] In a possible implementation, the connection mechanism 6 includes a connection rib 61 passing through the connection hole and a tensioning nut 62 arranged at the end of the connection rib 61 .

[0085] The connecting rib 61 is usually made of high-strength steel (such as alloy steel, etc.), which can ensure that it has sufficient strength and durability when bearing the preload. The tensioning nut 62 is also generally made of alloy steel and other materials to ensure good thread connection performance and anti-loosening ability.

[0086] During installation, special tools are required to stretch the connecting rib 61 to a predetermined length, and then tighten it with a tensioning nut 62 to generate a pre-tightening force in the structure. By rotating the nut, the tightness between it and the connected member can be adjusted to achieve the desired tensioning effect.

[0087] The application scenarios of the connecting rib 61 and the tensioning nut 62 are quite extensive. In the fields of mechanical structure, engineering construction, etc., the connecting rib 61 is often used in places that bear large tensile forces or need to maintain tight structural connections, such as prestressed ribs in bridges, pulley tensioning devices in mechanical transmissions, etc. The tensioning nut 62 is often used in situations where the relative position or tension between components needs to be adjusted and maintained, such as the tensioning device of a conveyor belt, the timing belt tensioner of an automobile engine, etc.

[0088] It should be noted that the specific materials, installation methods and application scenarios of the connecting ribs 61 and the tensioning nuts 62 may vary due to different engineering requirements and design standards. In actual applications, appropriate connecting ribs 61 and tensioning nuts 62 should be selected according to specific circumstances, and the relevant installation specifications should be strictly followed.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
