Description

Technical Field

[0001] This utility model relates to the field of coal mining, specifically to a fireproof rolling shutter door for coal mines. Background Technology

[0002] Fire safety is paramount in coal mine production environments. Coal mines contain large quantities of flammable materials and are relatively enclosed spaces; once a fire breaks out, it spreads rapidly with potentially catastrophic consequences. Fire-resistant roller shutters, as crucial fire-resistant partitions, effectively prevent the spread of fire and ensure the safe evacuation of personnel and the protection of property. Therefore, developing fire-resistant roller shutters suitable for coal mine environments is of significant practical importance.

[0003] Traditional fireproof rolling shutters used in coal mines often have gaps between the door and the frame when closed, which cannot effectively block the spread of smoke and fire, thus affecting the fireproof effect. Furthermore, traditional fireproof roller shutters typically use relatively simple and ordinary filling materials (such as ordinary glass wool or simple heat insulation felt), which are easily damaged in high-temperature environments and cannot withstand fire for a long time, thus failing to provide reliable protection for personnel evacuation and property.

[0004] Therefore, we have made improvements to this and proposed a fireproof rolling shutter door for coal mines. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a fireproof rolling shutter door for coal mines, which solves the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: Fireproof rolling shutters for coal mines are designed to solve the above problems.

[0007] The application is as follows: The device includes a roller shutter frame, a roller shutter storage cover installed on the upper side of the roller shutter frame, a roller shutter body that is rolled up inside the roller shutter storage cover, a controller installed on one side surface of the roller shutter storage cover, a groove opened inside the roller shutter frame, and the roller shutter body slidingly connected in the groove, and a sealing mechanism provided inside the roller shutter frame. The sealing mechanism includes a first connecting groove and a second connecting groove. The first connecting groove is formed on the surface of the grooves on both sides of the roller shutter door body. A sliding rod is slidably connected inside the first connecting groove, and a silicone pad is fixedly connected to one side surface of the sliding rod. Several electric push rods are fixedly installed inside the first connecting groove, and the telescopic ends of the electric push rods are fixedly connected to the surface of the sliding rod.

[0008] As a preferred technical solution of this application, a sliding rod and a silicone pad are also slidably arranged inside the second connecting groove, and a spring is fixedly installed between the surface of the sliding rod inside the second connecting groove and the inner wall of the second connecting groove.

[0009] As a preferred technical solution of this application, the interior of the roller shutter door body is filled with a first filling layer, a second filling layer and a third filling layer, and the exterior of the roller shutter door body is uniformly coated with a fireproof coating. The roller shutter door body is made of galvanized steel plate material.

[0010] As a preferred technical solution of this application, the first filling layer is filled with ceramic fiber cotton material.

[0011] As a preferred technical solution of this application, the second filling layer is filled with vermiculite material.

[0012] As a preferred technical solution of this application, the third filling layer is filled with rock wool material.

[0013] As a preferred technical solution of this application, the fireproof coating is made of intumescent steel structure fireproof coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the use of a sealing mechanism, first connecting grooves are opened on the recessed surfaces of both sides of the roller shutter door. An electric push rod moves the sliding rod and silicone pad, ensuring a tight fit against the roller shutter door. Simultaneously, a spring-assisted seal is installed in another connecting groove. This allows for rapid and tight sealing of the gap between the door and the frame when the roller shutter door is closed, forming a reliable sealing barrier. This effectively blocks the spread of smoke and fire, significantly improving fire resistance, buying valuable time for evacuation, and providing strong protection for property.

[0015] 2. By incorporating multiple filling layers and fire-retardant coatings, the first filling layer uses ceramic fiber cotton, which boasts excellent high-temperature resistance and heat insulation properties. The second filling layer uses vermiculite, further enhancing the fireproof and heat-insulating effects. The third filling layer uses rock wool, providing good heat insulation and fire resistance. Furthermore, the exterior of the roller shutter door is uniformly coated with an intumescent steel structure fire-retardant coating. Under high-temperature conditions, this coating rapidly expands to form a dense heat insulation layer, effectively preventing heat transfer. The combined effect of the filling materials and fire-retardant coating ensures the roller shutter door maintains structural stability for extended periods under high-temperature conditions, resisting fire attacks and providing reliable protection for personnel evacuation and property.

[0023] To address the technical problems in the background section, the following fireproof rolling shutter door for coal mines is provided: Combination Figure 1 - Figure 4 As shown, the present invention provides a fireproof rolling shutter door for coal mines, including a rolling shutter door frame 1, a rolling shutter door storage cover 2 installed on the upper side of the rolling shutter door frame 1, a rolling shutter door body 3 rolled up inside the rolling shutter door storage cover 2, and a controller 4 installed on one side surface of the rolling shutter door storage cover 2. A groove 5 is provided inside the rolling shutter door frame 1, and the rolling shutter door body 3 is slidably connected in the groove 5. A sealing mechanism 6 is provided inside the rolling shutter door frame 1. The sealing mechanism 6 includes a first connecting groove 601 and a second connecting groove 605. The first connecting groove 601 is opened on the surface of the groove 5 on both sides of the rolling shutter door body 3. A sliding rod 602 is slidably connected inside the first connecting groove 601, and a silicone pad 603 is fixedly connected to one side surface of the sliding rod 602. A plurality of electric push rods 604 are fixedly installed inside the first connecting groove 601, and the telescopic end of the electric push rod 604 is fixedly connected to the surface of the sliding rod 602.

[0024] In this embodiment: A roller shutter door storage cover 2 is installed on the upper side of the roller shutter door frame 1, and the roller shutter door body 3 is rolled up inside the roller shutter door storage cover 2. The raising and lowering of the roller shutter door body 3 can be conveniently controlled by the controller 4. A groove 5 is opened inside the roller shutter door frame 1, and the roller shutter door body 3 is slidably connected in the groove 5. The sealing mechanism 6 provided inside the roller shutter door frame 1 includes a first connecting groove 601 opened on the surface of the groove 5 on both sides of the roller shutter door body 3. A sliding rod 602 is slidably connected in the first connecting groove 601. A silicone pad 603 is fixedly connected to one side of the sliding rod 602, and several electric push rods 604 are fixedly installed in the first connecting groove 601. The telescopic end of the electric push rod 604 is fixedly connected to the surface of the sliding rod 602. When the roller shutter door is closed, the electric push rod 604 can be activated to push the sliding rod 602 and the silicone pad 603 to move, tightly fitting the roller shutter door body 3, achieving effective sealing, and greatly improving the sealing performance and fireproof effect of the fireproof roller shutter door.

[0025] In a preferred embodiment, a sliding rod 602 and a silicone pad 603 are also slidably disposed inside the second connecting groove 605, and a spring 606 is fixedly installed between the surface of the sliding rod 602 inside the second connecting groove 605 and the inner wall of the second connecting groove 605.

[0026] In this embodiment: when the roller shutter door 3 is closed, the spring 606 in the second connecting groove 605 can be squeezed, and the auxiliary sliding rod 602 and the silicone pad 603 always remain in close contact with the roller shutter door 3, forming a more reliable seal. At the same time, the elasticity of the spring 606 can also buffer a certain impact force, extend the service life of the roller shutter door, and comprehensively improve the performance of the fireproof roller shutter door for coal mines.

[0027] In a preferred embodiment, the interior is filled with a first filling layer 301, a second filling layer 302 and a third filling layer 303, and the exterior of the roller shutter door 3 is uniformly coated with a fireproof coating 304. The roller shutter door 3 is made of galvanized steel sheet.

[0028] In this embodiment, the roller shutter door body 3 is filled with a first filling layer 301, a second filling layer 302, and a third filling layer 303. Each filling layer has excellent properties and works synergistically to enhance the fireproof and heat insulation effect. At the same time, a fireproof coating 304 is uniformly applied to the outside of the roller shutter door body 3, which can further improve the fireproof effect. The roller shutter door body 3 is made of galvanized steel plate material. The galvanizing process gives it excellent corrosion resistance and mechanical strength, ensuring that the roller shutter door can still play a stable and reliable fireproof separation role for a long time in the complex and harsh environment of the coal mine.

[0029] In a preferred embodiment, the first filling layer 301 is filled with ceramic fiber cotton material.

[0030] In this embodiment: ceramic fiber cotton has extremely low thermal conductivity, which can effectively prevent heat transfer in high-temperature environments. It also has excellent high-temperature resistance, is not easily combustible, and has good chemical stability. It can withstand the complex thermal stress and chemical erosion that may occur in the coal mine environment for a long time. In the event of a fire, it can quickly play a role in heat insulation, delay the spread of fire, and buy precious time for personnel to escape and rescue.

[0031] In a preferred embodiment, the second filling layer 302 is filled with vermiculite material.

[0032] In this embodiment: Vermiculite, as a natural and non-toxic mineral material, expands under high temperature conditions to form a porous and dense heat-insulating structure. This property makes it excellent in absorbing and dispersing heat. When applied to the roller shutter door body 3, it can effectively enhance the fire resistance limit of the door body. In the event of a fire, it can further slow down the transfer of heat to the other side of the door body, providing a more reliable guarantee for fireproof partitioning inside the coal mine.

[0033] In a preferred embodiment, the third filling layer 303 is filled with rock wool material.

[0034] In this embodiment, rock wool material is known for its excellent heat insulation performance and good fire resistance. It can not only effectively block the transfer of heat, but also maintain the stability of the structure in high-temperature environments. It is not easily combustible and does not produce toxic gases. This further enhances the overall fireproof and heat insulation effect of the roller shutter door, providing more reliable safety protection for the coal mine environment and ensuring that the spread of fire can be effectively delayed in emergency situations such as fires.

[0035] As a preferred embodiment, the fire-retardant coating 304 is made of an intumescent steel structure fire-retardant coating.

[0036] In this embodiment: When the intumescent fireproof coating for steel structures is exposed to high temperature or flame, it can rapidly expand to form a thick and dense carbonized heat insulation layer. This heat insulation layer not only effectively isolates heat transfer and reduces the temperature of the roller shutter door body 3, but also prevents direct contact and spread of flames to a certain extent, thus improving fire resistance.

[0037] Under normal conditions, the roller shutter door 3 is rolled up inside the roller shutter door storage cover 2, and its raising and lowering can be controlled by the controller 4. The roller shutter door 3 slides within the groove 5 of the roller shutter door frame 1. When the roller shutter door is closed, the sealing mechanism 6 takes effect. The electric push rod 604 in the first connecting groove 601 is activated, pushing the sliding rod 602 and the silicone pad 603 to move and tightly fit the roller shutter door 3 to achieve a preliminary seal. At the same time, the roller shutter door 3 compresses the spring 606 in the second connecting groove 605, assisting the sliding rod 602 and the silicone pad 603 to maintain a tight fit and form a reliable seal. In terms of fire resistance, the roller shutter door 3 is made of galvanized steel plate and filled with three layers of different materials: the first filling layer 301 is ceramic fiber cotton, which has low thermal conductivity and high temperature resistance and can prevent heat transfer; the second filling layer 302 is vermiculite, which expands at high temperatures to form a heat insulation structure and slow down heat transfer; the third filling layer 303 is rock wool, which is heat-insulating and fireproof. The externally applied intumescent fireproof coating 304 for steel structures expands at high temperatures to form a carbonized heat insulation layer, effectively isolating heat and preventing the spread of flames, thus comprehensively improving the fireproof effect.
