Description

Technical Field

[0001] The present invention belongs to the technical field of fire simulation, and particularly relates to a dynamic fire smoke diffusion humanoid escape training demonstration device. Background Technique

[0002] In recent years, significant progress has been made in fire simulation technology, which is widely used in the fields of fire safety and building design. Through computational fluid dynamics (CFD) simulation, the heat flow, smoke propagation, and personnel evacuation during a fire can be accurately analyzed, helping to design safer buildings.

[0003] Most of the existing fire simulation technologies are through computer software simulation. There are few physical displays of the smoke diffusion process in buildings, which cannot be intuitively demonstrated and have poor practicability. This phenomenon has become an urgent problem to be solved by those in this field. Summary of the Invention

[0004] The purpose of the present invention is to provide a dynamic fire smoke diffusion humanoid escape training demonstration device for the existing skidding device to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A dynamic fire smoke diffusion humanoid escape training demonstration device, including a frame structure composed of columns and partitions. Glass plates are installed on the four edges of the partition, and the glass plates are connected to the columns. A simulated staircase is installed between the upper and lower partitions. Through holes are opened on the partition and are located above the simulated staircase. A smoke generation tank is fixedly installed above the bottom partition. The top of the smoke generation tank is connected through a smoke channel, and one end of the smoke channel is fixedly installed with a smoke nozzle through welding. This enables observers to clearly see the internal smoke diffusion process. A simulated staircase is set between the partitions to simulate the structure of a real staircase, helping training personnel understand the importance of the staircase as an evacuation route in a real fire environment. A smoke generation tank is set above the bottom partition, and a smoke generation device is installed in the tank. The generated smoke is guided to the nozzle through the smoke channel. The smoke nozzle can evenly release smoke during training to simulate the smoke diffusion at the fire scene and form a real training environment. The through-hole design on the partition allows the smoke to flow freely, simulating the smoke propagation path during a real fire, thereby providing a more realistic escape training scenario. Demonstrating the smoke diffusion process through a physical device can enable trainers to more intuitively understand the behavior of fire smoke and improve the effectiveness of training.

[0006] The present invention further illustrates that a fire extinguishing agent tank is fixedly installed above the partition plate at the bottom. A fire extinguishing agent passage is connected through the top of the fire extinguishing agent tank. A number of outer pipes are installed on the side wall of the fire extinguishing agent passage. The outer pipes are horizontally placed. Fire extinguishing agent spray heads are uniformly arranged in a straight line at the bottom of the outer pipes. The fire extinguishing agent spray heads are connected to the outer pipes through penetration. Once the system is started, the fire extinguishing agent flows from the tank into the outer pipes through the fire extinguishing agent passage and is sprayed out through the spray heads. Since the fire extinguishing agent spray heads are uniformly arranged at the bottom of the outer pipes, a larger area can be covered, the spraying uniformity of the fire extinguishing agent is improved, and the fire extinguishing effect is enhanced.

[0007] The present invention further illustrates that one end of the outer pipe is movably connected to the side wall of the fire extinguishing agent passage through a bearing. The outer pipe is connected to the fire extinguishing agent passage through penetration. A motor is fixedly installed on the side wall of the fire extinguishing agent passage. The output end of the motor is fixedly connected to the outer pipe. When the motor is started, the rotation of the motor will directly drive the rotation and swing of the outer pipe. This design not only achieves the multi-angle spraying effect of the spray heads but also can adjust the spraying direction and coverage range of the fire extinguishing agent according to needs, improving the flexibility and effectiveness of the fire extinguishing system. Through this dynamic adjustment mechanism, the training participants can experience more realistic fire extinguishing operations, increasing the practicality of emergency response.

[0008] The present invention further illustrates that a supplementary pipe is fixedly installed on the side wall of the fire extinguishing agent passage. A number of flexible branch pipes are installed at one end of the supplementary pipe. Fire extinguishing agent temporary storage cavities are uniformly distributed in a circular pattern on the inner wall of the outer pipe. A cylindrical sleeve is fixedly installed on one side of the fire extinguishing agent temporary storage cavity. One end of the cylindrical sleeve is connected to one end of the flexible branch pipe. In this way, the supplementary pipe is connected to the fire extinguishing agent temporary storage cavity of the outer pipe through the flexible branch pipe, forming a closed-loop supplementary system. When pumping the fire extinguishing agent, the fire extinguishing agent temporary storage cavity replenishes the fire extinguishing agent inside the outer pipe, thereby ensuring sufficient supply of the fire extinguishing agent during the fire extinguishing process and avoiding weakening of the fire extinguishing effect due to insufficient fire extinguishing agent.

[0009] The present invention further illustrates that a fluid pump is connected through penetration on one side of the fire extinguishing agent temporary storage cavity. A connection hose is connected through penetration at one end of the fluid pump. A flexible rubber hose is installed on the inner wall of the outer pipe. The flexible rubber hose is connected to the connection hose through penetration. One end of the connection hose communicates with the inner wall of the flexible rubber hose. The fluid pump is embedded in the inner wall of the outer pipe. When the fluid pump is started, the fire extinguishing agent in the fire extinguishing agent temporary storage cavity will be pumped into the inside of the outer pipe. The fluid pump provides strong power, enabling the fire extinguishing agent to be quickly and effectively transported from the temporary storage cavity to the inside of the outer pipe. This rapid replenishment ability can greatly improve the rapid response ability of fire extinguishing during a fire. The design of embedding the fluid pump in the outer pipe improves the overall stability of the system, avoiding leakage or detachment problems caused by external connections.

[0010] The present invention is further described as follows. Pressure sensors are evenly distributed along the inner wall of the outer tube in a circular pattern, and one end of each pressure sensor is in contact with the outer wall of the flexible rubber hose. By sensing the shortage of the fire extinguishing agent inside the flexible rubber hose through the pressure sensors, replenishment can be carried out.

[0011] The present invention is further described as follows. Arc-shaped inner grooves are also evenly distributed in the outer tube. Elastic folding bags are installed on the inner walls of the arc-shaped inner grooves. A one-way valve is connected in a through manner between the fire extinguishing agent storage cavity and the arc-shaped inner grooves. One side of the elastic folding bag is in contact with the outer wall of the flexible rubber hose. When the fire extinguishing agent in the flexible rubber hose is insufficient, it is sensed by the elastic folding bag. When the amount of the fire extinguishing agent in the flexible rubber hose drops to a certain threshold, the shape of the elastic folding bag will change due to the pressure change. Specifically, the bag will expand outward to sense the shortage of the internal fluid. When the elastic folding bag senses the shortage of the fire extinguishing agent in the flexible rubber hose, the change of the elastic folding bag will cause the one-way valve connected to one side of it to open, allowing the fire extinguishing agent to flow from the fire extinguishing agent storage cavity into the arc-shaped inner grooves.

[0012] The present invention is further described as follows. A connecting block is installed on one side of the elastic folding bag. One side of the connecting block is connected to a steel wire rope. A round hole is formed in the inner wall of the outer tube, and the steel wire rope passes through the round hole. A rotating shaft is rotatably installed on the outer wall of the outer tube. A winding wheel is installed on the outer wall of the rotating shaft. One end of the steel wire rope is wound around the winding wheel. By winding the steel wire rope around the winding wheel, the steel wire rope can be stored at this time, preventing the steel wire rope from accumulating in the arc-shaped inner grooves and hindering the work.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The dynamic fire smoke diffusion human-shaped escape training demonstration device of the present invention aims to enhance the intuitiveness and effectiveness of fire fighting training by physically demonstrating the diffusion process of smoke in a fire scenario. The smoke nozzles can evenly release smoke during the training process, simulate the smoke diffusion at the fire scene, form a real training environment, combine physical demonstration and simulation technology, and enhance the effectiveness and sense of participation of the training.

Detailed implementation manners

[0022] The technical solution of the present invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings in a non-limiting manner. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6, the present invention provides a technical solution: a dynamic fire smoke diffusion human escape training demonstration device, including a frame structure composed of a column 3 and a partition 2. Glass plates are installed on the four edges of the partition 2 and are connected to the column 3. A simulated staircase 21 is installed between the upper and lower partitions 2. Through holes are opened on the partition 2 and are located above the simulated staircase 21. A smoke generating tank 4 is fixedly installed above the bottom partition 2. The top of the smoke generating tank 4 is connected through a smoke passage 41. One end of the smoke passage 41 is fixedly installed with a smoke nozzle 42 by welding. The device adopts a frame structure combined with columns and partitions to form a closed simulation environment. Glass plates are equipped on the four edges of the partition, enabling observers to clearly see the internal smoke diffusion process. A simulated staircase is set between the partitions to simulate the structure of a real staircase and help training personnel understand the importance of the staircase as an evacuation passage in a real fire environment. A smoke generating tank is set above the bottom partition, and a smoke generating device is installed in the tank. The generated smoke is guided to the nozzle through the smoke passage. The smoke nozzle can evenly release smoke during training to simulate the smoke diffusion at the fire scene and form a real training environment. The through holes on the partition are designed to allow the smoke to flow freely, simulating the smoke propagation path in a real fire, thereby providing a more real escape training scenario. By physically demonstrating the smoke diffusion process, it can enable trainers to more intuitively understand the behavior of fire smoke and improve the effectiveness of training;

[0024] A fire extinguishing agent tank 5 is fixedly installed above the bottom partition 2. A fire extinguishing agent passage 51 is connected through the top of the fire extinguishing agent tank 5. A number of outer pipes 1 are installed on the side wall of the fire extinguishing agent passage 51. The outer pipes 1 are horizontally placed. The bottoms of the outer pipes 1 are evenly arranged in a straight line with fire extinguishing agent spray nozzles 99. The fire extinguishing agent spray nozzles 99 are connected through the outer pipes 1. The tank stores the fire extinguishing agent, providing the necessary fire extinguishing materials for the fire extinguishing system. The fire extinguishing agent passage 51 is responsible for transporting the fire extinguishing agent from the tank to the external spraying device. Once the system is started, the fire extinguishing agent flows from the tank through the fire extinguishing agent passage 51 into the outer pipes 1 and is sprayed out through the fire extinguishing agent spray nozzles 99. Since the fire extinguishing agent spray nozzles 99 are evenly arranged at the bottom of the outer pipes 1, they can cover a large area, improve the spraying uniformity of the fire extinguishing agent, and enhance the fire extinguishing effect;

[0025] One end of the outer pipe 1 is movably connected to the side wall of the fire extinguishing agent passage 51 through a bearing. The outer pipe 1 is connected to the fire extinguishing agent passage 51 in a through manner. A motor 98 is fixedly installed on the side wall of the fire extinguishing agent passage 51. The output end of the motor 98 is fixedly connected to the outer pipe 1. By starting the motor 98, the outer pipe 1 can be driven to rotate and swing. When the motor 98 is started, the rotation of the motor will directly drive the rotation and swing of the outer pipe 1. This design not only realizes the multi-angle spraying effect of the sprinkler head, but also can adjust the spraying direction and coverage range of the fire extinguishing agent according to needs, improving the flexibility and effectiveness of the fire extinguishing system. Through this dynamic adjustment mechanism, training participants can experience more realistic fire extinguishing operations, increasing the practicality of emergency response;

[0026] A supplementary pipe 46 is fixedly installed on the side wall of the fire extinguishing agent passage 51. One end of the supplementary pipe 46 is provided with a plurality of flexible branch pipes 45. The inner wall of the outer pipe 1 is evenly distributed in a circumferential manner with fire extinguishing agent storage cavities 12. One side of the fire extinguishing agent storage cavity 12 is fixedly installed with a cylindrical sleeve 11. One end of the cylindrical sleeve 11 is connected to one end of the flexible branch pipe 45. When pumping the fire extinguishing agent, the fire extinguishing agent storage cavity 12 replenishes the fire extinguishing agent inside the outer pipe 1. The design purpose is to temporarily store a part of the fire extinguishing agent inside the outer pipe for ready use. One side of the fire extinguishing agent storage cavity 12 is fixedly installed with a cylindrical sleeve 11, and one end of the cylindrical sleeve 11 is connected to one end of the flexible branch pipe 45. In this way, the supplementary pipe 46 is connected to the fire extinguishing agent storage cavity 12 of the outer pipe 1 through the flexible branch pipe 45, forming a closed-loop replenishment system. When pumping the fire extinguishing agent, the fire extinguishing agent storage cavity 12 replenishes the fire extinguishing agent inside the outer pipe 1, thereby ensuring sufficient supply of the fire extinguishing agent during the fire extinguishing process and avoiding weakening of the fire extinguishing effect due to insufficient fire extinguishing agent;

[0027] One side of the fire extinguishing agent storage cavity 12 is connected in a through manner with a fluid pump 92. One end of the fluid pump 92 is connected in a through manner with a connecting hose 93. A flexible rubber hose 13 is installed on the inner wall of the outer pipe 1. The flexible rubber hose 13 is connected in a through manner with the connecting hose 93. One end of the connecting hose 93 is in through connection with the inner wall of the flexible rubber hose 13. The fluid pump 92 is embedded and installed on the inner wall of the outer pipe 1. By starting the fluid pump 92, the fire extinguishing agent in the fire extinguishing agent storage cavity 12 is replenished into the inside of the outer pipe 1. The fluid pump 92 can be embedded and installed on the inner wall of the outer pipe 1, making the replenishment and transportation of the fire extinguishing agent more direct and effective. When the fluid pump 92 is started, the fire extinguishing agent in the fire extinguishing agent storage cavity 12 will be pumped into the inside of the outer pipe 1. The fluid pump 92 provides strong power, enabling the fire extinguishing agent to be quickly and effectively transported from the fire extinguishing agent storage cavity 12 to the inside of the outer pipe 1. This rapid replenishment ability can greatly improve the fire extinguishing rapid response ability during a fire. The design of embedding the fluid pump 92 in the outer pipe 1 improves the stability of the overall system, avoiding leakage or detachment problems caused by external connections;

[0028] The inner wall of the outer pipe 1 is evenly distributed with pressure sensors 91 in a circumferential manner. One end of the pressure sensor 91 is in contact with the outer wall of the flexible rubber hose 13. By sensing the lack of fire extinguishing agent inside the flexible rubber hose 13 through the pressure sensor 91, replenishment can be carried out.

[0029] The outer pipe 1 is also evenly distributed with arc-shaped inner grooves 14. The inner wall of the arc-shaped inner groove 14 is provided with an elastic folding bladder 15. A one-way valve 16 is connected in a through manner between the fire extinguishing agent storage cavity 12 and the arc-shaped inner groove 14. One side of the elastic folding bladder 15 is in contact with the outer wall of the flexible rubber hose 13. When the fire extinguishing agent in the flexible rubber hose 13 is insufficient, it is sensed through the elastic folding bladder 15. When the amount of fire extinguishing agent in the flexible rubber hose 13 drops to a certain threshold, the shape of the elastic folding bladder 15 will change due to the pressure change. Specifically, the bladder will expand outward to sense the lack of internal fluid. When the elastic folding bladder 15 senses the lack of fire extinguishing agent in the flexible rubber hose 13, the change of the elastic folding bladder 15 will cause the one-way valve 16 connected to one side of it to open, allowing the fire extinguishing agent to flow from the fire extinguishing agent storage cavity 12 into the arc-shaped inner groove 14.

[0030] One side of the elastic folding bladder 15 is provided with a connecting block 151. One side of the connecting block 151 is connected with a steel wire rope 17. A round hole is opened on the inner wall of the outer pipe 1, and the steel wire rope 17 passes through the round hole. A rotating shaft 172 is rotatably installed on the outer wall of the outer pipe 1. A winding wheel 171 is installed on the outer wall of the rotating shaft 172. One end of the steel wire rope 17 is wound on the winding wheel 171. By winding the steel wire rope 17 through the winding wheel 171, the steel wire rope 17 can be stored at this time, preventing the steel wire rope 17 from accumulating in the arc-shaped inner groove 14 and hindering the work.
