[0002] In industries such as power and communications, the safety of battery rooms is of paramount importance. The flammable gases such as hydrogen produced during the charging and discharging of batteries can easily cause an explosion if they reach their explosive limits and come into contact with a source of ignition, seriously threatening personnel safety and the normal operation of equipment.

[0003] Currently, there are many problems with explosion-proof walls in battery rooms. Traditional explosion-proof wall materials have limited explosion resistance and cannot withstand high-intensity explosive impacts; their fire resistance is insufficient and cannot effectively prevent the spread of fire; they are easily affected by environmental temperature and humidity, resulting in structural deformation and material aging, which leads to a decline in explosion-proof performance. Moreover, traditional explosion-proof walls are complicated to install, inefficient, have many gaps in the wall surface, are difficult to clean and maintain, and are prone to accumulating dirt and grime, affecting the indoor environment.

[0004] With the industry's increasing demands for the safety performance of battery rooms, there is an urgent need for a new type of explosion-proof wall that can overcome the shortcomings of traditional explosion-proof walls, provide more reliable explosion-proof and fire-proof protection, and also have good durability, convenient installation, and easy cleaning and maintenance.

[0007] Furthermore, the explosion-proof wall block includes explosion-proof panels and fireproof and heat-insulating materials. The explosion-proof wall block is composed of two explosion-proof panels and one fireproof and heat-insulating material, and explosion-proof panels are provided on both sides of the fireproof and heat-insulating material.

[0009] Furthermore, the explosion-proof plate has multiple recesses on its surface. These recesses are used to improve the strength of the explosion-proof plate and to disperse local stress when the explosion-proof plate encounters a local impact, thus preventing local deformation at the impact point.

[0010] Furthermore, the explosion-proof plate is composed of reinforced fiber cement board and double-sided pressure-galvanized steel plate. The fiber content of the reinforced fiber cement board reaches 15% to ensure that the explosion-proof plate itself has good compressive and bending resistance. The pressure-galvanized steel plate in the explosion-proof plate adopts hot-dip galvanizing process, and the zinc layer thickness on the pressure-galvanized steel plate is not less than 80μm.

[0011] Furthermore, the explosion-proof plate is provided with a fitting structure on both sides, and two adjacent explosion-proof plates can be spliced ​​together through this fitting structure, thereby allowing the explosion-proof plates to achieve a tightly fitted structure.

[0012] Furthermore, the keel frame support structure includes vertical channel steel and horizontal channel steel. After multiple vertical channel steels and multiple horizontal channel steels are connected, the vertical channel steels and horizontal channel steels can form an installation frame. The explosion-proof wall block is set in the installation frame. The vertical channel steels and horizontal channel steels are both made of high-strength steel.

[0013] Furthermore, the explosion-proof plate is installed on both sides of the keel frame support structure, and the explosion-proof plate is provided with multiple fastening components.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 4 As shown, a battery room explosion-proof wall based on a novel explosion-proof plate and a channel steel keel frame includes a keel frame support structure for supporting the wall and explosion-proof wall blocks for heat insulation and explosion protection. The explosion-proof wall blocks are fixed to the keel frame support structure, which is fixed to the concrete wall by multiple bolt columns. At key locations such as the edges, corners, and door and window openings of the keel frame support, additional steel reinforcement frames are set. This reinforcement structure significantly improves the load-bearing capacity of the explosion-proof wall at weak points, prevents the wall from cracking due to local stress concentration during an explosion, and further enhances the overall explosion-proof performance.

[0025] like Figures 1 to 4 As shown, the keel frame support structure includes vertical channel steel 102 and horizontal channel steel 103. The vertical channel steel 102 and horizontal channel steel 103 are fixed by bolts or welding. After multiple vertical channel steels 102 and multiple horizontal channel steels 103 are connected, the vertical channel steels 102 and horizontal channel steels 103 can form an installation frame. The explosion-proof wall block is set in the installation frame. The vertical channel steel 102 and horizontal channel steel 103 are both made of high-strength steel.

[0026] like Figures 1 to 4As shown, the explosion-proof wall block includes explosion-proof plates 101 and fireproof and heat-insulating material 104. The explosion-proof wall block is composed of two explosion-proof plates 101 and one fireproof and heat-insulating material 104. Explosion-proof plates 101 are provided on both sides of the fireproof and heat-insulating material 104. The explosion-proof plates 101 have the same shape as the mounting frame. The surface of the explosion-proof plates 101 is provided with multiple concave points. The concave points on the surface of the explosion-proof plates 101 are used to improve the strength of the explosion-proof plates 101. When the explosion-proof plates 101 encounter local impact, the concave points are used to disperse local stress and prevent local deformation of the explosion-proof plates 101 at the impact point. The two sides of the explosion-proof plates 101 are respectively provided with fitting structures. Two adjacent explosion-proof plates 101 can be spliced ​​through these fitting structures, thereby allowing the explosion-proof plates 101 to achieve a tightly installed structure.

[0027] like Figures 1 to 3 As shown, the explosion-proof plate 101 is composed of reinforced fiber cement board and double-sided pressure-galvanized steel plates. The reinforced fiber cement board uses high-strength, high-toughness special cement, combined with high-quality reinforcing fibers. The fiber content in the reinforced fiber cement board reaches 15% to ensure that the explosion-proof plate 101 itself has good compressive and bending resistance. The pressure-galvanized steel plates in the explosion-proof plate 101 are hot-dip galvanized, and the zinc layer thickness on the pressure-galvanized steel plate is not less than 80μm, ensuring that the explosion-proof plate 101 has excellent corrosion resistance in complex environments. The density of the explosion-proof plate 101 is controlled at 1800kg / m³. The explosion-proof plate 101 is the same size as the mounting frame diameter. Multiple fastening components 105 are provided on the explosion-proof plate 101. The explosion-proof plate 101 is connected to the vertical channel steel 102 through multiple fastening components 105. The explosion-proof plate 101 has an explosion resistance of 1.5MPa and can effectively withstand the energy level of an explosion of 500kJ. When the explosion overpressure peak reaches 100kPa, the maximum deformation of the explosion-proof plate 101 is controlled within 10mm, ensuring that the explosion-proof plate 101 can maintain its structural integrity after being subjected to the explosion impact and preventing secondary damage caused by the flying explosion fragments.

[0028] like Figures 1 to 4 As shown, the two explosion-proof panels 101 and the mounting frame form a fireproof chamber. The fireproof chamber is filled with fireproof and heat-insulating material 104. The fireproof and heat-insulating material 104 is made of materials that are not easily combustible and have a high melting point, such as rock wool and aerogel felt. The fireproof chamber is coated with a fireproof coating on both the inside and outside. This fireproof coating will expand rapidly at high temperatures to form a dense heat-insulating layer, further improving the fireproof and heat-insulating performance of the explosion-proof wall. The fireproof coating also has corrosion resistance and weather resistance, and can adapt to the complex environmental conditions of the battery room, maintaining its fireproof performance for a long time.

[0029] like Figures 1 to 3As shown, the explosion-proof plate 101 is installed on both sides of the keel frame support structure. The explosion-proof plate 101 is fixedly connected to the keel frame support structure through a fastening assembly 105. The fastening assembly 105 includes a screw 501 and a nut 502, which are connected by threads. One end of the screw 501 is located inside the vertical channel steel 102, and the nut 502 is located outside the explosion-proof plate 101. A high-strength flat washer 504 is provided between the nut 502 and the explosion-proof plate 101 to increase the strength of the nut 502. 2. The contact area with the explosion-proof plate 101 is increased to prevent the explosion-proof plate 101 from being damaged or deformed during the fastening process. A spring washer 503 is provided between the spring washer 503 and the nut 502 to prevent the nut 502 from loosening. The spring washer 503 is used to provide additional fastening force under vibration or impact. After the fastening assembly 105 is installed, a layer of sealant, such as silicone sealant, is applied around the nut 502, the high-strength flat washer 504, and the spring washer 503 to enhance the sealing effect of the high-strength flat washer 504 and prevent moisture from entering the fireproof cavity. Detailed Implementation

[0031] The explosion-proof board 101 is prepared by pressurizing and bonding reinforced fiber cement board with galvanized steel materials on both sides to ensure a tight bond between the materials, forming an explosion-proof board with high explosion resistance. During the production process, the quality and proportion of raw materials, as well as the production process parameters, are strictly controlled to ensure that the various performance indicators of the explosion-proof board meet the design requirements.

[0032] The keel frame support structure is fabricated by selecting appropriate specifications of channel steel according to the design dimensions and structural requirements of the explosion-proof plate 101. Vertical channel steel 102 and horizontal channel steel 103 are fabricated through cutting and welding processes. During the welding process, professional welding equipment and technicians are used, and welding process standards are strictly followed to weld the vertical channel steel 102 and horizontal channel steel 103 together, ensuring the dimensional accuracy and welding quality of the keel frame support structure. After welding is completed, the keel frame is thoroughly inspected to ensure there are no welding defects. During welding, attention should be paid to ensuring that the size of the installation frame corresponds to the dimensions of the explosion-proof plate 101.

[0033] For fireproof and heat-insulating materials 104, select fireproof and heat-insulating materials such as rock wool and aerogel felt that meet the fireproof performance requirements, cut and process them according to the design requirements of the fireproof chamber, and prepare them to fill the gaps in the fireproof chamber.

[0034] For wall assembly, at the installation location of the battery room, the keel frame support structure is welded and fixed to the nearby wall according to design requirements, while ensuring that the horizontal and verticality of the keel frame support structure meet the standards. Then, starting from the corner, the explosion-proof plates 101 are spliced ​​and installed sequentially according to the design order. During the splicing process, ensure that the concave and convex grooves of the explosion-proof plates 101 are accurately matched, and use the fastening assembly 105 to fix the explosion-proof plates to the channel steel keel frame. The high-strength flat washer 504 in the fastening assembly 105 seals the mounting holes on the explosion-proof plates 101, while the spring washer 503 pre-tightens the nut 5. 02. Prevent nut 502 from loosening; during installation, check the flatness and fixing firmness of explosion-proof plate 101 at any time; after installing one side of explosion-proof plate 101, fill the gap between the fireproof chambers with fireproof and heat-insulating material 104 and other materials. In addition, it should be noted that after the explosion-proof plate 101 is fixed on the keel support structure, fireproof coating can be sprayed inside and outside the explosion-proof plate 101. At the same time, a layer of sealant should be applied around nut 502, high-strength flat washer 504, and spring washer 503 to enhance the sealing effect of high-strength flat washer 504 and prevent moisture from entering the fireproof chamber.

[0035] After the wall installation is completed, acceptance should be carried out in accordance with relevant standards and specifications, checking the splicing quality of the explosion-proof panel 101, the welding firmness of the keel frame support structure, the fixing of the fastening components 105, the filling of the fireproof and heat-insulating material 104, and the thickness and quality of the fireproof coating, etc. During daily use, the wall should be inspected and maintained regularly, cleaning dust and stains on the wall surface in a timely manner, checking whether the fastening components 105 are loose, whether the explosion-proof panel 101 is damaged, and whether the keel frame support structure is deformed, etc. If any problems are found, they should be repaired or replaced in a timely manner.

[0036] After the wall is installed, it can be tested according to standard fire resistance testing methods (such as GB / T9978). The fire resistance time of this device can reach 4 hours. Furthermore, after the wall formed by this device is subjected to a high temperature environment of 1000℃ for 2 hours, the temperature rise of the back side of the explosion-proof plate 101 relative to the burning area does not exceed 180℃, effectively preventing heat transfer and preventing the fire from spreading to adjacent areas. Additionally, the coefficient of thermal expansion of this device after it is assembled into a wall is 8×10⁻⁻⁻⁶. 6 At / ℃, it exhibits good dimensional stability and is not prone to deformation in environments with significant temperature changes.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
