[0002] The purpose of the fire simulation trolley is mainly to improve the efficiency and safety of fire prevention, emergency response and fire fighting and rescue. Specifically: the fire simulation trolley can monitor and give early warnings in real time. By installing various sensors on the trolley, it can monitor the fire source, temperature and smoke concentration in the environment in real time. When a fire source is detected, the fire extinguishing vehicle can blow out or spray water to extinguish the fire source in time, and give an alarm through a buzzer to remind the nearby personnel to pay attention to the fire situation, so as to prevent the occurrence of fires.

[0003] The existing fire simulation trolley, as the main device for fire simulation experiments, mainly sets a driving module on the control circuit board and uses methods such as software programming, sensor integration and communication control to set a predetermined program for the fire simulation trolley, so as to complete the task of extinguishing the fire, and thus fully display the working process and principle of the fire extinguishing device to the viewers. However, the existing fire simulation trolley cannot participate in simulating fire scenarios under different types of fire sources. Therefore, after manufacturing a corresponding fire extinguishing vehicle according to the fire simulation trolley, it is difficult to arrange fire fighting equipment according to the specific type of fire source.

A protrusion 241 is arranged upward in the middle of the bottom guide rail 24, and a concave part is arranged at the position of the flared pipe guide track 25 above the protrusion 241;

[0037] A through hole 27 is formed on one side of the fixed plate 8. An elbow pipe 51 is arranged on one side of the through hole 27. The end of the elbow pipe 51 is connected with a spraying head 5;

[0038] A press handle guide track 26 is further arranged on one side of the flared pipe guide track 25; The flared pipe guide track 25 is fixed on one side of the fixed plate 8, and the press handle guide track 26 is also fixed to the flared pipe guide track 25;

[0039] When the flared tube guiding track 25 and the handle pressing guiding track 26 are in a fixed state, and when the flared tube guiding track 25 is in a fixed state with the fixed plate 8, the bottom of the fire extinguisher body 22 can be inserted into the fire extinguisher fixing seat 21 to facilitate the installation of the fire extinguisher body 22;

[0040] In this embodiment, specifically, the flared tube guiding track 25 includes two steel plates, and a sliding gap is provided between the two steel plates; a material tube 31 is provided at the top of the fire extinguisher body 22, a solenoid valve 32 is provided at one end of the material tube 31, a handle 33 of the gas cylinder valve is provided at one end of the material tube 31 close to the solenoid valve 32, the handle 33 can move in the sliding channel, and a flared tube 311 is fixed at the end of the material tube 31;

[0041] When the fire extinguisher fixing seat 21 reaches the protruding portion 241, the flared tube 311 is also located in the recess, and the flared tube 311 corresponds to the through hole 27;

[0042] In this embodiment, the handle pressing guiding track 26 includes two parallel plate bodies, a sliding channel is formed between the two plate bodies, the handle 33 can slide in the sliding channel, a concave channel is provided in the middle of the handle pressing guiding track 26, and when the handle 33 passes through the concave channel, the handle 33 moves downward following the track of the concave channel;

[0043] During the movement of the fire extinguisher fixing seat 21, the fire extinguisher fixing seat 21 drives the fire extinguisher body 22 to move simultaneously, the fire extinguisher body 22 drives the material tube 31, the solenoid valve 32, and the flared tube 311 to move, and after the handle 33 passes through the concave channel of the handle pressing guiding track 26, the handle 33 is pressed down, the fire extinguisher body 22 is in an open state, the controller 12 can open the solenoid valve 32, after the solenoid valve 32 is opened, the gas or foam or dry powder in the fire extinguisher is ejected, and under the action of pressure, it is ejected along the material tube 31 and the flared tube 311, passes through the elbow pipe 51, and finally is ejected from the spray head 5 and sprayed towards the fire source;

[0044] Preferably, a pressurizing device can be added in the middle of the elbow pipe 51 to increase the pressure of the fire extinguishing medium passing through the elbow pipe 51, thereby increasing its spraying pressure and being beneficial to high-pressure spraying.

[0045] As Figures 1-5 shown, the traction mechanism includes support plates 17 fixed at both ends of the top of the bottom guide rail 24, a motor 18 is provided on the support plates 17, a roller 20 is connected to the end of the output shaft of the motor 18, and a steel cable 19 is wound around the roller 20;

[0046] In this embodiment, specifically, after starting the motor 18, the output shaft of the motor 18 drives the roller 20 to rotate and wind the steel cable 19. The steel cable 19 simultaneously pulls the fire extinguisher fixing seat 21, and the fire extinguisher fixing seat 21 moves horizontally on the bottom guide rail 24. The rollers 20 of the two traction mechanisms rotate in opposite directions, so that the fire extinguisher fixing seat 21 can be pulled back to its original position.

[0047] As Figures 1-8 shown, traction rings 30 are symmetrically arranged on the outer wall of the fire extinguisher fixing seat 21. The extending end of the steel cable 19 can be fixedly connected to the traction ring 30. A slider 28 is fixed to the bottom of the fire extinguisher fixing seat 21. A chute 23 is formed at the top of the bottom guide rail 24. The slider 28 is matched with the chute 23. A slide bar 29 is further arranged at the bottom end of the fire extinguisher fixing seat 21.

[0048] Specifically, three fire extinguisher fixing seats 21 can be arranged on the fire extinguishing mechanism 10 on one side of the vehicle body 9, and one fire extinguishing mechanism 10 can also be arranged on the other side. Similarly, three fire extinguishers can be arranged on the fire extinguishing mechanism 10. The three fire extinguishers are a dry powder fire extinguisher, a carbon dioxide fire extinguisher, and a foam fire extinguisher respectively. The three fire extinguishers can be used to extinguish fires caused by books or wood, electrical fires in the computer room, and oil fires respectively. Using corresponding fire extinguishers for different fire sources can quickly and accurately demonstrate the process of extinguishing fires.

[0049] As Figures 1-3 shown, a water tank 13 is further arranged on the top of the vehicle body 9. A cover body 16 is arranged at the water inlet of the water tank 13. The water outlet of the water tank 13 is connected with a guiding pipe 14. The end of the guiding pipe 14 is connected with a water pump 7. The water outlet of the water pump 7 is connected with a water outlet pipe 15. The end of the water outlet pipe 15 is fixed with an atomizing nozzle 6. The atomizing nozzle 6 and the spraying head 5 are both fixed on the same connecting block 11. And a linear motor 4 for driving the connecting block 11 to move horizontally is arranged at the bottom of the connecting block 11; The linear motor 4 is horizontally fixed at the front of the vehicle body 9. The electric sliding block on the linear motor 4 can drive the connecting block 11 to swing left and right horizontally;

[0050] Specifically, after the vehicle body 9 reaches the fire source position, the water pump 7 is started. The water pump 7 pumps the water in the water tank 13. The water passes through the guiding pipe 14 and the water outlet pipe 15, and then is sprayed out from the atomizing nozzle 6. The atomizing nozzle 6 sprays water mist, which can spray the fire source over a large area, so as to extinguish the fire source. The linear motor 4 can drive the connecting block 11 to move horizontally, and the connecting block 11 can drive the spraying head 5 and the atomizing nozzle 6 to move left and right, so as to drive the spraying head 5 and the atomizing nozzle 6 to change directions.

[0051] As Figure 9As shown in the figure, a rotating shaft 36 is fixed to the bottom end of the detection head 2. The bottom end of the rotating shaft 36 is connected to a secondary gearbox 34. The secondary gearbox 34 is a gear reduction mechanism, and its specific structure has been disclosed in the prior art. The input shaft end of the secondary gearbox 34 is connected to a motor 35. An installation box 1 is also provided outside the secondary gearbox 34. Specifically, during the movement of the vehicle body 9, the motor 35 drives the secondary gearbox 34 to rotate. The gears inside the secondary gearbox 34 rotate and transmit mechanical power to the rotating shaft 36. The end of the rotating shaft 36 drives the detection head 2 to rotate. Thus, by using the sensor network integration module inside the detection head 2, which integrates a flame sensor, a smoke sensor, and a temperature sensor, the environment around the vehicle body 9 can be detected, so as to identify a fire source. Then, through AI vision recognition technology and Internet of Things cloud platform technology, the information is transmitted to the controller 12, and the controller 12 then controls the vehicle body 9 to move to the fire source position.

[0052] Embodiment 2:

[0053] As Figures 4-7 shown in the figure, an iron ring 52 is also fixed inside the through hole 27. One end of the iron ring 52 is fixedly connected to the end of the elbow pipe 51. An electromagnet 53 is also provided on one side wall of the iron ring 52;

[0054] In this embodiment, the output shaft of the motor 18 drives the winding roller 20 to rotate. The winding roller 20 winds the steel cable 19. The steel cable 19 drives the fire extinguisher fixing seat 21. The fire extinguisher fixing seat 21 moves on the top of the bottom guide rail 24. After the fire extinguisher fixing seat 2 moves to the top of the protrusion 241, since the three fire extinguisher fixing seats 21 are pulled and tightened by the steel cables 19 at both ends of the top of the bottom guide rail 24, they will not slide off the top of the protrusion 241 randomly. At this time, the end of the flared pipe 311 coincides with the end of the iron ring 52. Since the electromagnet 53 has magnetism, an iron plate is connected between the electromagnet 53 and the iron ring 52. The iron plate will be magnetized by the magnetic field of the electromagnet 53 to form a new magnet. Thus, this new magnet (the iron plate) will generate a magnetic field in its surrounding space, and then affect the iron ring 52. The magnetic field generated after the iron plate is magnetized will be conducted to the iron ring 52, causing the iron ring 52 to also be affected by the magnetic field and have magnetism. Thus, the flared pipe 311 can be magnetically adsorbed. The flared pipe 311 is made of iron with an anti-rust coating on its outer surface, and the flared pipe 311 is in a flared shape, which is beneficial for the gas inside the fire extinguisher bottle to be sprayed into the elbow pipe 51.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
