[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] like Figures 1 to 4As shown, a tunnel fire accident rescue teaching demonstration device includes a base 1, a mountain model 2 and a tunnel model 3 are provided on the top of the base 1, the tunnel model 3 is located inside the mountain model 2, the tunnel model 3 includes a tunnel pipe 4, a risk avoidance system 6, a lighting system 9 and a smoke exhaust system 10, a plurality of vehicle models 7 are arranged in the tunnel pipe 4, each vehicle model 7 is equipped with a smoke system 13 and a heating system 14, a water-based fire extinguisher 5 is provided in the tunnel pipe 4 corresponding to each vehicle model 7, a plurality of smoke detectors 11 and a temperature detector 12 are also arranged in the tunnel pipe 4, a controller 8 is provided outside the base 1, and the risk avoidance system 6, the lighting system 9, the smoke exhaust system 10, the smoke system 13, the heating system 14, the water-based fire extinguisher 5, the smoke detector 11 and the temperature detector 12 are all electrically connected to the controller 8; the mountain model 2 is missing to expose part of the tunnel pipe 4, and part of the tunnel pipe 4 is sealed with a transparent glass cover.

[0024] The smoke and high temperature generated by a vehicle fire accident are simulated through the smoke system 13 and the heating system 14. The controller 8 activates the evacuation system 6, the lighting system 9, the smoke exhaust system 10 and the water-based fire extinguisher 5 to carry out rescue after the fire accident. The effectiveness of the rescue is judged according to the numerical values ​​collected by the smoke detector 11 and the temperature detector 12, and the best evacuation route is known. Through multiple demonstrations of this device, the working states of the smoke exhaust system 10 and the water-based fire extinguisher 5 are changed, so that trainees can master the working states of the smoke exhaust system 10 and the water-based fire extinguisher 5 for effective cooling and smoke evacuation, as well as the best evacuation route.

[0025] It should be noted that in order to improve the accuracy of the teaching demonstration, the tunnel pipe 4, the escape system 6 (the evacuation passage inside the tunnel), the lighting system 9 and the smoke exhaust system 10 are set according to the tunnel to be simulated, only scaled down in proportion. The route combined with the low values ​​collected by the smoke detector 11 and the temperature detector 12 is the optimal evacuation route.

[0026] Example 2

[0027] like Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically as follows:

[0028] The smoke detector 11 is arranged in front of the temperature detector 12 . The smoke detector 11 and the temperature detector 12 are equidistantly distributed on one side of the inner cavity of the tunnel pipe 4 close to the hazard avoidance system 6 .

[0029] The smoke detector 11 and the temperature detector 12 are arranged together to detect the smoke concentration and temperature inside the tunnel pipe 4. By distributing multiple smoke detectors 11 and temperature detectors 12 at equal intervals, data on the smoke concentration and temperature at various locations in the tunnel pipe 4 are collected, making it easy to know the best evacuation route, thereby guiding personnel to evacuate in time from low smoke and low temperature areas into the evacuation system 6.

[0030] Example 3

[0031] like Figures 2 to 3 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically as follows:

[0032] Heating system 14 includes a heating wire 141 disposed within the interior of vehicle model 7. This heating wire 141 heats vehicle model 7, simulating the high temperatures generated by a vehicle fire. This temperature is controllable and the simulation is accurate. Vehicle model 7 is integrally formed from a thermally conductive plastic. This plastic dissipates the heat generated by heating wire 141 and provides insulation, which does not affect the operation of heating system 14. This effectively simulates the high temperatures of a fire accident. Furthermore, the plastic is waterproof, preventing damage to heating wire 141 within vehicle model 7 during use by a water-based fire extinguisher 5.

[0033] Example 4

[0034] like Figures 2 to 3 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically as follows:

[0035] An installation slot is provided at the bottom of the vehicle model 7, and the smoke system 13 is arranged in the installation slot. The smoke system 13 is a smoke generator 131, which emits smoke to simulate the smoke generated by a vehicle fire. The amount of smoke is controllable and the simulation is accurate. In addition, the smoke system 13 is arranged in the installation slot at the bottom of the vehicle model 7, which can effectively prevent the water-based fire extinguisher 5 from causing damage to the smoke system 13 during use.

[0036] Example 5

[0037] like Figures 2 to 3 As shown, this embodiment is a further improvement on the basis of any one of the embodiments 1 to 4, specifically as follows:

[0038] Each vehicle model 7 is provided with a water-based fire extinguisher 5 at the four corners. By providing the water-based fire extinguisher 5 at the four corners of the vehicle model 7, the rescue effects of vehicles involved in fire accidents at different angles can be simulated respectively, thereby guiding trainees on how to effectively extinguish the burning vehicles in subsequent tunnel fire accidents.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
