Description

Technical Field

[0001] This utility model relates to the field of explosion-proof door technology, specifically an explosion-proof air defense door. Background Technology

[0002] In the field of civil defense engineering, early civil defense doors were relatively simple in their blast-resistant design. Most of them relied solely on the strength of a single door panel material to withstand the impact of an explosion, lacking an effective buffer structure. This resulted in the door body being unable to fully disperse and absorb the huge impact force generated instantly when an explosion occurred, making the door body extremely prone to severe deformation or even damage. Consequently, it could not effectively protect the protected area behind it, and the safety of personnel and materials faced a great threat.

[0003] On the other hand, after long-term use or exposure to explosions, the sealing effect will be greatly reduced, and it will be unable to effectively prevent the infiltration of harmful gases and radioactive materials. Once a dangerous situation occurs in the surrounding environment, such as the leakage of harmful gases or changes in external pressure, the air defense door will not be able to respond in time to strengthen the seal, thus creating a safety hazard in the protected area and making it difficult to meet the complex and ever-changing safety protection needs of modern times. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof air defense door to solve the problems of simple explosion-proof design without effective buffer structure, poor sealing effect and difficulty in timely response to dangerous situations.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An explosion-proof air-raid shelter door includes a frame, with door panels on the front and rear sides of the frame. A support frame is connected through the inner side of the frame, and a buffer assembly and a steel pipe are connected through the inner side of the support frame. The buffer assembly has two sets facing each other, and the steel pipe is located at the center of the two sets of buffer assemblies. A skeleton is fixedly installed on the front and rear side walls of the buffer assembly. A sealing mechanism is provided on the outer side wall of the frame. The sealing mechanism includes a telescopic assembly, an electric cylinder, a sensor group, and a controller. The electric cylinder is located on the inner side wall of the telescopic assembly. The inner end of the sensor group is fixedly connected to the inner end of the electric cylinder, and the outer end of the sensor group is fixedly connected to the inside of the controller. The sealing mechanism extends through the front side of the door panel to the surface of the door panel.

[0007] Furthermore, the buffer assembly includes a U-shaped tube and a support. The U-shaped tube is provided in two sets, front and back, and is located opposite to the front and back sides of the frame. The steel pipe is located at the center of the U-shaped tube, and the side end of the support is fixedly connected to the inner wall of the frame. The buffer assembly located inside the support frame begins to function, and the two sets of opposite U-shaped tubes are the key components for buffering.

[0008] Furthermore, the inner side of the bracket is fitted onto the outer wall of the U-shaped tube, and when subjected to impact, the liquid inside the U-shaped tube will flow rapidly within the tube.

[0009] Furthermore, the outer wall of the telescopic component penetrates the side wall of the frame, and the controller is located on the outer surface of the door panel. The signal is transmitted to the controller, and after receiving the signal, the controller starts the electric cylinder.

[0010] Furthermore, the telescopic assembly includes a bonding plate and a folding plate. The inner and outer ends of the electric cylinder are fixedly connected to the inner sidewall of the bonding plate. Since the folding plate is connected to the front and rear ends of the two sets of bonding plates, during the outward movement of the bonding plate...

[0011] Furthermore, the bonding plate is provided with two sets, inner and outer, and the folding plate is provided at the front and rear ends of the two sets of bonding plates. As the bonding plate moves outward, the folding plate will unfold.

[0012] Furthermore, a handle is provided at the center of the front side of the door panel, and a base is fixedly connected to the bottom of the frame.

[0013] Compared with the prior art, this utility model provides an explosion-proof air defense door, which has the following beneficial effects:

[0014] This blast-resistant air-raid shelter door, through its buffer components, front and rear layout, and the combination of steel pipes and a frame structure, effectively buffers and disperses the impact force when facing an explosion, greatly enhancing the overall blast-resistant performance of the door and reducing the damage caused by the explosion to the door body and the protected area behind it. The sensor group in the sealing mechanism can monitor relevant environmental conditions in real time. Once an anomaly is detected, it can promptly transmit a signal to the controller. The controller drives the electric cylinder to move the telescopic components, achieving a tight seal at the door seams and other parts, effectively blocking harmful gases and radioactive materials, ensuring the safety of the protected area. Overall, this improves the reliability of the air-raid shelter door in terms of blast resistance and sealing protection, better protecting the safety of personnel and materials.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0024] like Figures 1-7 As shown, an explosion-proof air defense door includes a frame 1, door leaf panels 2 are provided on the front and rear sides of the frame 1, a support frame 3 is connected through the inner side of the frame 1, a buffer assembly 4 and a steel pipe 5 are connected through the inner side of the support frame 3, the buffer assembly 4 is provided in two sets facing each other, the steel pipe 5 is located at the center of the two sets of buffer assemblies 4, a skeleton 6 is fixedly installed on the front and rear side walls of the buffer assembly 4, a sealing mechanism 7 is provided on the outer side wall of the frame 1, the sealing mechanism 7 extends through the front side of the door leaf panel 2 to the surface of the door leaf panel 2, a handle 8 is provided in the middle of the front side of the door leaf panel 2, and a base 9 is fixedly connected to the bottom of the frame 1.

[0025] like Figure 5 , Figure 6As shown, the buffer assembly 4 includes a U-shaped tube 41 and a support 42. The U-shaped tube 41 is provided in two sets, front and rear, and is located on the front and rear sides of the frame 6 in opposite directions. The steel pipe 5 is located at the center of the U-shaped tube 41. The side end of the support 42 is fixedly connected to the inner wall of the frame 6, and the inner side of the support 42 is sleeved on the outer wall of the U-shaped tube 41. Since the support 42 fixes the U-shaped tube 41 to the frame 6, when subjected to impact force, the liquid in the U-shaped tube 41 will flow rapidly in the tube, through the compression, expansion and circulation of the liquid in the U-shaped tube. Example 2:

[0026] like Figure 1 and Figure 4 As shown, the sealing mechanism 7 includes a telescopic assembly 71, an electric cylinder 72, a sensor group 73, and a controller 74. The electric cylinder 72 is located on the inner wall of the telescopic assembly 71. The inner end of the sensor group 73 is fixedly connected to the inner end of the electric cylinder 72, and the outer end of the sensor group 73 is fixedly connected to the inside of the controller 74. The outer wall of the telescopic assembly 71 penetrates the side wall of the frame 1. The controller 74 is located on the outer surface of the door panel 2. The sensor group 73 monitors the environmental parameters around the air-raid shelter door in real time. When the sensor group 73 detects an abnormal situation, it transmits a signal to the controller 74. After receiving the signal, the controller 74 activates the electric cylinder 72. The electric cylinder 72 starts working and pushes the inner bonding plate 711 to move outward.

[0027] like Figure 7 As shown, the telescopic assembly 71 includes a bonding plate 711 and a folding plate 712. The inner and outer ends of the electric cylinder 72 are fixedly connected to the inner sidewall of the bonding plate 711. The bonding plate 711 is provided with two sets, inner and outer. The folding plate 712 is provided at the front and rear ends of the two sets of bonding plates 711. During the process of the bonding plate 711 moving outward, the folding plate 712 will unfold, thereby causing the entire telescopic assembly 71 to extend outward and fit tightly against the gap between the door frame and the door leaf panel 2.

[0028] Working principle: such as Figures 1-7 As shown, when the air-raid shelter door is subjected to an explosion, the impact force first acts on the door panel 2, and the door panel 2 transmits the force to the support frame 3.

[0029] The buffer assembly 4 located inside the support frame 3 begins to function, with the two sets of opposing U-shaped tubes 41 being key components for buffering. Since the bracket 42 fixes the U-shaped tubes 41 to the frame 6, when subjected to impact, the liquid inside the U-shaped tubes 41 will flow rapidly within the tubes. Through the compression, expansion, and circulation of the liquid within the U-shaped tubes, the enormous impact force generated by the explosion is converted into other forms of internal and kinetic energy, thereby effectively mitigating the damage to the overall structure of the air-raid shelter door and playing a buffering and protective role. At the same time, the steel pipe 5 located at the center of the two sets of U-shaped tubes 41 can enhance the structural strength of the entire buffer assembly, enabling it to better withstand and disperse the impact force.

[0030] The sensor group 73 monitors the environmental parameters around the air defense door in real time. When the sensor group 73 detects an abnormal situation, it transmits the signal to the controller 74. After receiving the signal, the controller 74 starts the electric cylinder 72. The electric cylinder 72 starts working and pushes the inner bonding plate 711 to move outward.

[0031] Since the folding plate 712 is connected to the front and rear ends of the two sets of bonding plates 711, the folding plate 712 will unfold as the bonding plate 711 moves outward, thereby causing the entire telescopic assembly 71 to extend outward and fit tightly against the gap between the door frame and the door leaf panel 2, or to cooperate closely with the surrounding sealing structure, effectively filling the gap and preventing harmful gases, radioactive materials, etc. from entering the interior of the air-raid shelter door through the door gap, ensuring the sealing performance of the air-raid shelter door and providing a reliable protective barrier for the protected area.
