Description

Technical Field

[0001] This invention belongs to the field of fire protection technology, specifically relating to a fire protection device that can be extended and retracted in multiple dimensions. Background Technology

[0002] With the development of modern electronic technology, high-performance storage devices or systems can meet the needs of modern commerce, industry, scientific research, and other fields, offering advantages such as high reliability, large available bandwidth, and strong environmental adaptability. Storage devices or systems are typically deployed in office buildings, residences, shopping malls, and other locations, and have high fire protection requirements. In the event of a fire, the fireproof device deploys, forming a bottomless cubic enclosure that covers the storage device or system, providing sealing protection, fire resistance, and heat insulation, protecting the safety and integrity of the internal equipment at high temperatures. Currently, to meet the heat insulation requirements of the protected equipment, multiple layers of fire blankets and fire-resistant fiber cotton are used to cover the outside of the equipment, resulting in excessively thick and heavy fireproof layers. When these layers are retracted, they are difficult to roll up and take up a lot of space. Fully unfolding or retracting them takes time, prolonging the time the equipment is exposed to fire and reducing the safety factor. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a fireproof device capable of multi-dimensional retraction and folding, comprising a receiving top cover, a support portion, an outer folding receiving portion, and an inner folding receiving portion. The protected equipment is placed below the receiving top cover, and the outer and inner folding receiving portions are located inside the receiving top cover for folding and storing the outer and inner fireproof fiber cotton, respectively.

[0004] The outer folding storage section includes four outer storage components forming a square frame. Each outer storage component includes several stacked outer storage plates, so that the outer fireproof fiber cotton is stacked around the outer storage plates. The inner folding storage section includes four inner storage components forming a square frame. Each inner storage component includes several stacked inner storage plates, so that the inner fireproof fiber cotton is stacked around the inner storage plates.

[0005] The support is located below the containment cover and outside the protected equipment; the support includes two outer support assemblies and two inner support assemblies for winding and accommodating the outer and inner fire blankets, respectively.

[0006] In the fireproof device described in this invention, when the fireproof material is fully unfolded during a fire, it forms concentric layers of fireproof material (with a square cross-section), arranged from the outside in: an outer fireproof blanket (single layer), an outer layer of fireproof fiber cotton, an inner fireproof blanket (double layer), and an inner layer of fireproof fiber cotton. To improve the fire resistance rating, aluminum foil can be added to the inner layer of each fireproof material. Since the total thickness of the aforementioned fireproof materials is excessive, traditional methods of overall rolling or folding would occupy a large amount of space and be difficult to store and retract.

[0007] This invention separates and stores fire blankets and fire-resistant fiber cotton according to their different properties. The fire blanket is wound around a vertical support and stored in two layers, an outer layer and an inner layer, to avoid affecting the unfolding and retraction of the outer layer of fire-resistant fiber cotton. The outer and inner layers of fire-resistant fiber cotton are stored separately using the outer and inner folding storage parts, which reduces the volume and weight of the storage top cover, while making full use of the space around the protected equipment.

[0008] Optionally, the protected device is securely fixed to a base on the ground, and a housing cover is suspended above the protected device and securely connected to the roof, with the housing cover completely covering the maximum cross-section of the protected device.

[0009] Optionally, the receiving cover is a hollow cube with an empty bottom surface. Its four top corners are designated as Top Corner 1, Top Corner 2, Top Corner 3, and Top Corner 4 in a clockwise direction. Two first motors are installed at Top Corner 1, Top Corner 3, Top Corner 2, and Top Corner 4. Two first motors are installed at Top Corner 1, Top Corner 3, Top Corner 2, and Top Corner 4. Each outer support assembly includes two outer supports, and each inner support assembly includes two inner supports.

[0010] Four first motors are respectively connected to and drive the four outer pillars to rotate, so as to unfold or retract the outer fireproof blanket; four second motors are respectively connected to and drive the four inner pillars to rotate, so as to unfold or retract the inner fireproof blanket; the outer and inner pillars are both vertically arranged, and the bottom ends of the outer and inner pillars are rotatably connected to the ground or base.

[0011] Further optionally, the bottom surface of the four sides of the receiving cover is provided with an upper outer track, with the track surface of the upper outer track facing down, corresponding to the four outer fireproof blankets of the four outer pillars respectively; a lower outer track is provided on the ground or base at the position corresponding to the upper outer track, with the track surface of the lower outer track facing up.

[0012] Each outer fire blanket has several sliders 1 evenly arranged on its upper edge and several sliders 2 evenly arranged on its lower edge. Slider 1 is slidably connected to the upper outer track, and slider 2 is slidably connected to the lower outer track, so that when the outer support rolls up or unrolls the outer fire blanket, the outer fire blanket can move along the upper and lower outer tracks.

[0013] Further optionally, the outer fireproof blanket is square, with one vertical side of the outer fireproof blanket fixed to the corresponding outer support, and a vertically arranged magnet on the other vertical side;

[0014] The two outer pillars of the same outer pillar assembly rotate in opposite directions when unrolling. After the two outer fire blankets are unrolled, they form two adjacent sides of a cube, which are at a 90° angle to each other. After the two outer fire blankets of the two outer pillars of another outer pillar assembly are unrolled, they form the other two sides of the cube, which are at a 90° angle to each other.

[0015] Two external fire blankets, which are at a 90° angle to each other and are released from different external support components, are attracted to each other by their respective magnets to achieve closure.

[0016] Further optionally, a vertical partition is provided between the outer receiving assembly and the inner receiving assembly, and the four partitions form a square.

[0017] The bottom surface of the partition plate is provided with two parallel upper inner rails with a certain gap between them. The rails of the upper inner rails face downwards. The ground or base is provided with a lower inner rail corresponding to the position of the upper inner rails, with the rails of the lower inner rails facing upwards. The four partition plates correspond to the four sets of inner fire blankets of the four inner pillars. Each set of inner fire blankets includes two parallel inner fire blankets, and each inner fire blanket corresponds to one upper inner rail and one outer inner rail.

[0018] Each inner fire blanket has several sliders 3 evenly distributed along its upper edge and several sliders 4 evenly distributed along its lower edge. Slider 3 is slidably connected to the upper inner track, and slider 4 is slidably connected to the lower inner track, so that when the inner support rolls up or unrolls the inner fire blanket, the inner fire blanket can move along the upper and lower inner tracks.

[0019] Further optionally, the inner fireproof blanket is square, with one vertical side of the inner fireproof blanket fixed to the corresponding inner support, and a vertically arranged magnet on the other vertical side;

[0020] The two inner pillars of the same inner pillar assembly rotate in opposite directions when unrolling. After the two inner fire blankets are unrolled, they form two adjacent sides of a cube, which are at a 90° angle to each other. After the two inner fire blankets released from the two inner pillars of another inner pillar assembly are unrolled, they form the other two sides of the cube, which are at a 90° angle to each other.

[0021] Two inner fire blankets, which are at a 90° angle to each other and are released from different inner support components, are attracted to each other by their respective magnets to achieve closure.

[0022] Optionally, the four outer receiving components of the outer folding receiving part are respectively arranged close to and parallel to the four sides of the receiving top cover, and two support plates are respectively provided at the four apex positions close to the inside of the receiving top cover. The two ends of the outer receiving plate are respectively fixed to the sides of the two opposing support plates at the adjacent apex.

[0023] The outer receiving panels of the same outer receiving assembly are of the same size and are evenly arranged from top to bottom. There are gaps between adjacent outer receiving panels to allow the outer fireproof fiber cotton to pass through them. The outer receiving panels are arranged horizontally.

[0024] Guide rails are provided on the support plates at both ends of the outer receiving plate, so that the top support rod and bottom support rod of the outer fireproof fiber cotton can move back and forth along the guide rails, thereby driving the outer fireproof fiber cotton to pass between the outer receiving plates.

[0025] Further optionally, the first guide rail is a continuous, meandering serpentine shape, comprising several horizontal and vertical sections connected in sequence. An outer receiving plate is between adjacent horizontal sections, and an outer receiving plate corresponds horizontally to each vertical section. Each outer receiving plate corresponds to a vertical section on one side and to the opening of the serpentine guide rail on the other side.

[0026] Optionally, the outer fireproof fiber cotton is square, with a top support rod 1 embedded inside the top edge and a bottom support rod 1 embedded inside the bottom edge. The two ends of the top support rod 1 are respectively slidably connected to the guide rails 1 on the corresponding two support plates 1 via sliders 5, and can move up or down along the guide rails 1. The two ends of the bottom support rod 1 are respectively provided with sliders 6. When the top support rod 1 moves to the top of the guide rail 1, the outer fireproof fiber cotton is completely folded and stacked on each of the outer receiving plates of the same outer receiving assembly, and the two sliders 6 of the bottom support rod 1 just enter the guide rail 1 and are at the bottom of the guide rail 1.

[0027] Optionally, the outer fireproof fiber cotton is provided with vertical soft magnetic strips on both vertical sides, so that after the outer fireproof fiber cotton is unfolded, adjacent outer fireproof fiber cottons are attracted and fastened together by the soft magnetic strips.

Detailed Implementation

[0038] This embodiment provides a fireproof device that can be extended and retracted in multiple dimensions, such as... Figures 1-9 As shown, it includes a top cover 1, a support part, an outer folding storage part and an inner folding storage part. The protected device 2 is placed below the top cover 1. The outer folding storage part and the inner folding storage part are located inside the top cover 1 and are used to fold and store the outer fireproof fiber cotton 3 and the inner fireproof fiber cotton 4 respectively.

[0039] The outer folding storage section includes four outer storage components 5 forming a square frame. Each outer storage component 5 includes several stacked outer storage plates 7, so that the outer fireproof fiber cotton 3 is stacked around the outer storage plates 7. The inner folding storage section includes four inner storage components 6 forming a square frame. Each inner storage component 6 includes several stacked inner storage plates 8, so that the inner fireproof fiber cotton 4 is stacked around the inner storage plates 8.

[0040] The support is located below the housing cover 1 and outside the protected equipment 2; the support includes two outer support components and two inner support components, which are used to wind and store the outer fire blanket 18 and the inner fire blanket 19, respectively.

[0041] Optionally, the protected device 2 is securely fixed on a base on the ground, the base being made of fire-resistant material, and the housing cover 1 is suspended above the protected device 2 and securely connected to the roof, the housing cover 1 completely covering the maximum cross-section of the protected device 2.

[0042] Optionally, the receiving top cover 1 is a hollow cube with an empty bottom surface. Its four top corners are designated as top corner 1 (9), top corner 2 (10), top corner 3 (11), and top corner 4 (12) in a clockwise direction. Two first motors 13 are installed at top corner 1 (9) and top corner 3 (11). Two second motors 14 are installed at top corner 2 (10) and top corner 4 (12). Each outer support assembly includes two outer supports 16, and each inner support assembly includes two inner supports 17.

[0043] Four first motors 13 are respectively connected to and drive four outer support columns 16 to rotate, so as to unfold or roll up the outer fireproof blanket 18; four second motors 14 are respectively connected to and drive four inner support columns 17 to rotate, so as to unfold or roll up the inner fireproof blanket 19; the outer support columns 16 and inner support columns 17 are both vertically arranged, and the bottom ends of the outer support columns 16 and inner support columns 17 are rotatably connected to the ground.

[0044] Optionally, the receiving cover 1 has a square cross-section, with two outer support components and two inner support components corresponding to the four vertices of the cross-section of the receiving cover 1. The two inner support components are located at positions that move towards the inside of the receiving cover from the upper vertices 10 and 12, respectively. The two outer support components are located at the two ends of one diagonal of the cross-section, and the two inner support components are located at the two ends of the other diagonal of the cross-section.

[0045] Further optionally, an upper outer track 20 is provided on the bottom surface of each of the four sides of the receiving cover 1, with the track surface of the upper outer track 20 facing downwards, corresponding to the four outer fireproof blankets 18 of the four outer support columns 16 respectively; a lower outer track 21 is provided on the ground or base at the position corresponding to the upper outer track 20, with the track surface of the lower outer track 21 facing upwards.

[0046] Each outer fire blanket 18 has several sliders 1 evenly arranged on its upper edge and several sliders 2 evenly arranged on its lower edge. Slider 1 is slidably connected to the upper outer track 20 and slider 2 is slidably connected to the lower outer track 21, so that when the outer support 16 rolls up or unrolls the outer fire blanket 18, the outer fire blanket 18 can move along the upper outer track 20 and the lower outer track 21.

[0047] Further optionally, there is a gap between the two outer pillars 16 of the same outer pillar assembly, so that the two outer pillars 16 do not affect each other after being wrapped with their respective outer fireproof blankets 18.

[0048] Fireproof shell 1 is provided on the outside of the two outer pillars 16 of the same outer pillar assembly to protect the inner outer pillars 16 and outer fireproof blankets 18; the top of the fireproof shell 1 is provided with an opening for the outer pillars 16 to connect to the first motor 13; both sides of the fireproof shell 1 are provided with vertical elongated openings for the two outer fireproof blankets 18 to enter and exit the fireproof shell 1.

[0049] Further optionally, the outer fireproof blanket 18 is square, with one vertical side of the outer fireproof blanket 18 fixed to the corresponding outer support 16, and a vertically arranged magnet 1 on the other vertical side. The height of the magnet 1 is slightly less than the height of the vertical side. The magnet 1 is fixed inside the vertical side of the outer fireproof blanket 18 to prevent the magnet 1 from being exposed to the outside and conducting heat.

[0050] The two outer pillars 16 of the same outer pillar assembly rotate in opposite directions when unrolling. After the two outer fire blankets 18 are unrolled, they form two adjacent sides of a cube and are at a 90° angle to each other. After the two outer fire blankets 18 released from the two outer pillars 16 of another outer pillar assembly are unrolled, they form the other two sides of the cube and are at a 90° angle to each other.

[0051] Two outer fire blankets 18, which are at a 90° angle to each other and are released from different outer support components, attract each other through their respective magnets to achieve closure.

[0052] Further optionally, a vertical partition 24 is provided between the outer receiving component 5 and the inner receiving component 6. The height of the partition 24 is equal to the height of the side of the receiving top cover 1, and the four partitions 24 form a square.

[0053] The bottom surface of the partition plate 24 is provided with two parallel upper inner rails 22, with a certain gap between the two upper inner rails 22. The rail surface of the upper inner rails 22 faces downward. The ground or base is provided with two lower inner rails 23 corresponding to the positions of the two upper inner rails 22, with the rail surface of the lower inner rails 23 facing upward. The four partition plates 24 correspond to the four sets of inner fire blankets of the four inner support columns 17. Each set of inner fire blankets includes two parallel inner fire blankets 19, and each inner fire blanket corresponds to one upper inner rail 22 and one lower inner rail 23.

[0054] Each inner fire blanket 19 has several sliders 3 evenly arranged on its upper edge and several sliders 4 evenly arranged on its lower edge. Slider 3 is slidably connected to the upper inner track 22 and slider 4 is slidably connected to the lower inner track 23, so that when the inner support 17 rolls up or unrolls the inner fire blanket 19, the inner fire blanket 19 can move along the upper inner track 22 and the lower inner track 23.

[0055] Optionally, the four apex corners of the square formed by the partition plate 24 correspond one-to-one with the four apex corners of the receiving top cover 1, and the second motor 14 is located at the corresponding upper apex corners two and four of the square, and the second motor 14 is located at the top or bottom of the partition plate 24.

[0056] Further optionally, there is a gap between the two inner pillars 17 of the same inner pillar assembly, so that the two inner pillars 17 do not affect each other after being wound with their respective inner fireproof blankets 19.

[0057] Fireproof shells are provided on the outer sides of the two inner pillars 17 of the same inner pillar assembly to protect the inner pillars 17 and the inner fireproof blankets 19 inside. The top of the fireproof shell is provided with an opening for the inner pillars 17 to connect to the second motor 14. Vertical elongated openings are provided on both sides of the fireproof shell for the two sets of inner fireproof blankets 19 to enter and exit the fireproof shell.

[0058] Further optionally, the inner fireproof blanket 19 is square, with one vertical side of the inner fireproof blanket 19 fixed to the corresponding inner support 17, and a vertically arranged magnet 2 on the other vertical side. The height of the magnet 2 is slightly less than the height of the vertical side of the inner fireproof blanket 19. The magnet 2 is fixed inside the vertical side of the inner fireproof blanket 19 to prevent the magnet 2 from being exposed to the outside and conducting heat.

[0059] The two inner pillars 17 of the same inner pillar assembly rotate in opposite directions during unwinding. After the two inner fire blankets 19 are unwound, they form two adjacent sides of a cube (the cross-section of this cube is smaller than the cross-section of the cube enclosed by the outer fire blanket 18) and form an angle of 90° with each other. After the two inner fire blankets 19 released from the two inner pillars 17 of another inner pillar assembly are unwound, they form the other two sides of the cube and form an angle of 90° with each other.

[0060] Two inner fire blankets 19, which are at a 90° angle to each other and are released from different inner support components, attract each other through their respective magnets to achieve closure.

[0061] The outer support column 16 and inner support column 17 of the present invention can support and accommodate the top cover 1, and simultaneously accommodate the fireproof blanket. In one specific embodiment, the first and second outer support columns are installed within one fireproof housing, and the third and fourth outer support columns are installed within another fireproof housing. The first outer support column corresponds to the winding of the first outer fireproof blanket, the second outer support column corresponds to the winding of the second outer fireproof blanket, the third outer support column corresponds to the winding of the third outer fireproof blanket, and the fourth outer support column corresponds to the winding of the fourth outer fireproof blanket. All the outer fireproof blankets are square when unfolded. Each outer fireproof blanket 18 moves linearly along its corresponding upper outer track 20 and lower outer track 21 to achieve winding or unwinding. The end of the first outer fireproof blanket furthest from the first outer support column generally moves towards the adjacent inner support column, and the end of the third outer fireproof blanket furthest from the third outer support column generally moves towards the same inner support column. That is, the first and third outer fireproof blankets approach each other, and ultimately their magnets attract each other, causing them to close. Similarly, the end of the second outer fire blanket furthest from the second outer support generally approaches the adjacent inner support, and the end of the fourth outer fire blanket furthest from the fourth outer support generally approaches the same inner support. That is, the second and fourth outer fire blankets approach each other, and eventually their magnets attract each other, causing them to close. When all four outer fire blankets are fully deployed, they can completely cover the space from the bottom of the top cover 1 to the ground or base, blocking external heat, smoke, or flames.

[0062] Compared to the outer support column 16, the inner support column 17 is offset slightly inward from the top cover 1 to provide space for the outer folding receiving section. The structure and operation of the inner support column assembly are similar to the outer support column assembly, except that the inner fire blankets 19 on each side are double-layered. The double-layered inner fire blankets 19 wound on the inner support column 17 are tightly fitted together, saving space. The two parallel upper inner tracks 22 merge into one track near the inner support column. The sliders of the two inner fire blankets 19 pass along this track one after the other, and when they reach the fork, they enter the corresponding upper inner track 22, creating a gap between the two inner fire blankets 19, forming an air layer for better insulation. The lower inner track 23 is similarly configured. Slider 1, slider 2, slider 3, and slider 4 can all communicate with an external control device to control the movement of each slider in conjunction with each motor. When the four sets of inner fire blankets are fully unfolded, they can completely cover the space from the bottom of the partition plate 24 to the ground or base, blocking external heat.

[0063] Optionally, the four outer receiving components 5 of the outer folding receiving part are respectively arranged close to and parallel to the four sides of the receiving top cover 1. Two support plates 25 are respectively provided at the four apex positions close to the inside of the receiving top cover 1. The two ends of the outer receiving plate 7 are respectively fixed to the sides of the two opposing support plates 25 at the adjacent apex positions to fix the outer receiving plate 7.

[0064] The outer receiving plates 7 of the same outer receiving assembly 5 are of the same size and are evenly arranged from top to bottom. There are gaps between adjacent outer receiving plates 7 to allow the outer fireproof fiber cotton 3 to pass between adjacent outer receiving plates 7. The outer receiving plates 7 are arranged horizontally.

[0065] The support plates 25 at both ends of the outer receiving plate 7 are equipped with guide rails 27, which allow the top support rod 36 and bottom support rod 37 of the outer fireproof fiber cotton 3 to move back and forth along the guide rails 27, thereby driving the outer fireproof fiber cotton 3 to pass between the outer receiving plates 7.

[0066] Optionally, the two support plates 25 at one corner of the receiving top cover 1 are perpendicular to each other. The top edge of the support plate 25 is fixedly connected to the top surface of the receiving top cover 1, one side is fixedly connected to the side of the receiving top cover 1, and the other side is fixedly connected to the side of the corresponding support plate 25. The right angle formed by the two support plates 25 is diagonally opposite to the corner of the receiving top cover 1. The outer receiving plate 7 is connected to the side of the support plate 25 away from the corresponding corner of the receiving top cover 1.

[0067] Optionally, the guide rail 27 is a continuous, meandering serpentine guide rail, comprising several horizontal and vertical sections connected in sequence. An outer receiving plate 7 is located between adjacent horizontal sections, and an outer receiving plate 7 corresponds horizontally to each vertical section. Each outer receiving plate 7 has only one side corresponding to the vertical section and the other side corresponding to the opening of the serpentine guide rail 27.

[0068] Optionally, the outer receiving plate 7 is provided with rotatable rollers 28 on both sides. The rollers 28 are parallel to the length direction of the outer receiving plate 7, and the two ends of the rollers 28 are rotatably connected to the two ends of the length direction of the outer receiving plate 7, so that when the outer fireproof fiber cotton 3 passes through the edge of the outer receiving plate 7, the resistance is reduced and the movement is smoother.

[0069] Further optionally, the outer fireproof fiber cotton 3 is square, with a top support rod 36 embedded inside the top edge and a bottom support rod 37 embedded inside the bottom edge. The two ends of the top support rod 36 are respectively slidably connected to the guide rails 27 on the two corresponding support plates 25 through sliders 5, and can move up or down along the guide rails 27.

[0070] The bottom support rod 37 has sliders 6 at both ends. When the top support rod 36 moves to the top of the guide rail 27, the outer fireproof fiber cotton 3 is folded and stacked on each of the outer receiving plates 7 of the same outer receiving assembly 5. The two sliders 6 of the bottom support rod 37 just enter the guide rail 27 and are at the bottom of the guide rail 27.

[0071] Preferably, the guide rail 27 is provided with limiting devices at both the bottom and top. The bottom limiting device can limit the slider 6 to prevent the bottom support rod 37 from slipping off the guide rail 27, and the top limiting device can limit the slider 5 to ensure that the top support rod 36 moves into place and does not slip.

[0072] Further optionally, adjacent containment components are perpendicular to each other, and only one outer containment plate 7 is provided at the same height for each adjacent containment component;

[0073] The bottom of the guide rail 27 is close to the inside of the receiving top cover 1, that is, close to the partition plate 24, so that when the outer fireproof fiber cotton 3 is fully unfolded, it is in a vertical state, and the bottom outer receiving plate 7 is close to the inside of the receiving top cover 1 (close to the partition plate).

[0074] Optionally, the outer fireproof fiber cotton 3 is provided with vertical soft magnetic strips on both vertical sides, so that when the outer fireproof fiber cotton 3 is unfolded, adjacent outer fireproof fiber cotton 3 are attracted and fastened together by the soft magnetic strips; the length of the soft magnetic strip is slightly less than the height of the vertical side of the inner fireproof blanket 19, and the soft magnetic strip is embedded in the interior of the vertical side of the inner fireproof blanket 19.

[0075] In this invention, a layered storage method is used for the outer layer fire-retardant fiber cotton 3. Four pieces of outer layer fire-retardant fiber cotton 3 are respectively placed on four outer receiving components 5. When unfolded, the fiber cotton is vertical and can cover the space between the bottom outer receiving plate 7 and the ground or base, blocking external heat. When storing the outer layer fire-retardant fiber cotton 3, both ends of the top support rod 36 move along the corresponding guide rails, causing the outer layer fire-retardant fiber cotton 3 to move serpentinely between the outer receiving plates 7, equivalent to wrapping around each outer receiving plate 7, achieving folded storage. When the top support rod 36 moves to the top of the guide rail, the bottom support rod 37 also moves to the bottom of the guide rail, and sliders five and six are respectively limited, realizing the storage of the outer layer fire-retardant fiber cotton 3. When the outer fire-resistant fiber cotton 3 needs to be unfolded, the limiting position is released, and the top support rod 36 moves downward along the guide rail, pushing the outer fire-resistant fiber cotton 3 to fall downward in the opposite direction. The bottom support rod 37 hangs down naturally. Under the action of the outer fire-resistant fiber cotton 3's own weight, the outer fire-resistant fiber cotton 3 can be unfolded solely by the top support rod 36. When the top support rod 36 moves to the bottom of the guide rail, it is limited, and the outer fire-resistant fiber cotton 3 is fully unfolded. The outer fire-resistant fiber cotton 3 is generally composed of several layers of aluminosilicate fiber cotton.

[0076] The inner folding receiving part, inner receiving component 6, inner receiving plate 8 and inner fireproof fiber cotton 4 have the same structure, function and operation mode as the outer folding receiving part, outer receiving component 5, outer receiving plate 7 and outer fireproof fiber cotton 3, respectively. The difference is that the inner folding receiving part, inner receiving component 6, inner receiving plate 8 and inner fireproof fiber cotton 4 are located closer to the inside of the receiving top cover 1.

[0077] Optionally, the four inner receiving components 6 of the inner folding receiving part are respectively arranged close to and parallel to the four sides of the receiving top cover 1. Two support plates 26 are respectively provided at the four corners of the receiving top cover 1 and close to the inside of the receiving top cover 1. The two ends of the inner receiving plate 8 are respectively fixed to the sides of the two opposing support plates 26 at the adjacent corners to fix the inner receiving plate 8.

[0078] The inner receiving plates 8 of the same inner receiving assembly 6 are of the same size and are evenly arranged from top to bottom. There are gaps between adjacent inner receiving plates 8 to allow the inner fireproof fiber cotton 4 to pass through. The inner receiving plates 8 are arranged horizontally.

[0079] The inner receiving plate 8 has guide rails 2 on the support plates 26 at both ends, so that the top support rod 2 and bottom support rod 2 of the inner fireproof fiber cotton 4 can move back and forth along the guide rails 2, thereby driving the inner fireproof fiber cotton 4 to pass between the inner receiving plates 8.

[0080] Alternatively, two support plates 26 corresponding to one corner of the receiving top cover 1 are perpendicular to each other, with the top edge of the support plate 26 fixedly connected to the top surface of the receiving top cover 1 and one side fixedly connected to the side of the corresponding other support plate 26; the inner receiving plate 8 is connected to the side of the support plate 26 away from the corresponding corner of the receiving top cover 1.

[0081] Optionally, the second guide rail is a continuous, meandering serpentine guide rail, comprising several horizontal and vertical sections connected in sequence. An inner receiving plate 8 is between adjacent horizontal sections, and an inner receiving plate 8 corresponds horizontally to each vertical section. Each inner receiving plate 8 has only one side corresponding to the vertical section and the other side corresponding to the opening of the serpentine guide rail.

[0082] Optionally, the inner receiving plate 8 is provided with rotatable rollers on both sides. The rollers are parallel to the length direction of the inner receiving plate 8, and the two ends of the rollers are rotatably connected to the two ends of the length direction of the inner receiving plate 8. This reduces the resistance and makes the movement smoother when the inner fireproof fiber cotton 4 passes the edge of the inner receiving plate 8.

[0083] Further optionally, the inner fireproof fiber cotton 4 is square, with a top support rod 2 embedded inside the top edge and a bottom support rod 2 embedded inside the bottom edge. The two ends of the top support rod 2 are respectively slidably connected to the guide rails 2 on the corresponding two support plates 26 through sliders 7, and can move up or down along the guide rails 2.

[0084] The bottom support rod 2 has sliders 8 at both ends. When the top support rod 2 moves to the top of the guide rail 2, the inner fireproof fiber cotton 4 is folded and stacked on the inner receiving plates 8 of the same inner receiving assembly 6. The two sliders 8 of the bottom support rod 2 just enter the guide rail 2 and are at the bottom of the guide rail 2.

[0085] Preferably, the guide rail 2 is provided with limiting devices at both the bottom and top. The bottom limiting device can limit the slider 8 to prevent the bottom support rod 2 from slipping off the guide rail 2, and the top limiting device can limit the slider 7 to ensure that the top support rod 2 moves into place and does not slip.

[0086] Further optionally, adjacent containment components are perpendicular to each other, and each adjacent containment component has only one inner containment plate 8 at the same height;

[0087] The bottom of the second guide rail is close to the inside of the top cover 1, that is, away from the partition plate 24, so that when the inner fireproof fiber cotton 4 is fully unfolded, it is in a vertical state, and the bottom inner receiving plate 8 is close to the inside of the top cover 1 (away from the partition plate).

[0088] Optionally, vertical soft magnetic strips are provided on both vertical sides of the inner fireproof fiber cotton 4, so that when the inner fireproof fiber cotton 4 is unfolded, adjacent inner fireproof fiber cotton 4 are attracted and fastened together by the soft magnetic strips; the length of the soft magnetic strips is slightly less than the height of the vertical side of the inner fireproof blanket 19, and the soft magnetic strips are embedded inside the vertical side of the inner fireproof blanket 19.

[0089] If the aforementioned fireproof layers still cannot meet the fireproof and heat insulation requirements of the protected equipment, several more fireproof blankets can be installed inside the inner fireproof fiber cotton 4 (i.e., closer to the protected equipment). These several fireproof blankets form an integral cubic cover 31. The cover 31 has a top surface and four sides, but no bottom surface. When the cover 31 housing assembly is unfolded, it can cover the outside of the protected equipment and play a protective role.

[0090] Optionally, the interior of the receiving top cover 1 and the interior of the inner folding receiving part is provided with a winding storage assembly. The winding storage assembly includes two parallel winding shafts 35, a steel wire 34 and two third motors 15. The rotating shafts of the two third motors 15 are respectively connected to one end of the two winding shafts 35, and the other end of the two winding shafts 35 are respectively rotatably connected to a vertical suspension rod 32. The top end of the suspension rod 32 is connected to the top surface of the receiving top cover 1, and the bottom end is suspended.

[0091] A winding shaft 35 is parallel to one side of the top surface of the cover 31. The two apex corners of this side are respectively connected to the corresponding winding shaft 35 by several strands of steel wire 34. When the third motor 15 drives the winding shaft 35 to rotate, the winding shaft 35 realizes the folding or unfolding of the cover 31 by winding or unwinding the steel wire 34.

[0092] Further optionally, the lower surface of the top surface of the receiving cover 1 is provided with parallel guide rails 29 and 30, with the track surfaces of guide rails 29 and 30 facing downwards, and guide rail 29 perpendicular to the winding shaft 35; the top end of the suspension rod 32 is slidably connected to guide rail 29 through slider 9, and the winding rod is rotatably connected to the bottom end of suspension rod 32.

[0093] The third motor 15 is connected to the guide rail 30 via a vertical suspension rod 2 33. The top of the suspension rod 2 33 is slidably connected to the guide rail 4 30 via a slider 10. The bottom of the suspension rod 2 33 is suspended in the air. The third motor 15 is fixedly connected to the bottom of the suspension rod 2 33.

[0094] The corresponding suspension rods 32 and 33 move at corresponding positions and speeds on guide rails 29 and 30, ensuring that the winding rod is straight.

[0095] When the cover 31 needs to be retracted, the two winding shafts 35 are positioned directly above the two opposite sides of the top surface of the cover 31. The third motor 15 drives the corresponding winding shaft 35 to rotate, thereby winding the steel wire 34. At this time, the cover 31 maintains its cubic shape and is lifted upwards. After all the steel wire 34 has been wound up, the two suspension rods 32 move towards each other (i.e., move closer to each other) on the guide rail 29. The movement of the suspension rod 33 matches the movement of the corresponding suspension rod 32, making the two winding shafts 35 parallel to each other. In this way, the distance between the two winding shafts 35 is less than the length of the cover 31 when it is unfolded, causing the cover 31 to contract. As the winding shafts 35 continue to rotate, the cover 31 can be wound onto the winding shafts 35. The distance between the two winding shafts 35 can be adjusted according to the size of the cover 31 until the cover 31 is completely wound onto the winding shafts 35. When the cover 31 is unfolded, the above operation is reversed.
