[0002] In fire drills, the simulation materials for fires are mostly combustible materials such as grass and wood, which are ignited by pouring fuels such as gasoline. The smoke generated by this method is large, which not only pollutes the environment, but also easily causes harm to the human body, and at the same time cannot be reused. Therefore, a fire smoke simulator is particularly needed.
[0003] During the use of the fire smoke simulation device, in order to better simulate the effect of fire smoke, it is necessary to adjust the range of the smoke ejected by the fire smoke simulation device. However, the existing fire smoke simulation devices do not have the function of range adjustment, which limits the smoke simulation and thus reduces the working efficiency. Summary of the Utility Model

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

An ejection nozzle is fixedly installed at the output end on the outer side of the adjustment box. An adjustment groove is opened inside the bottom end of the simulation box body. A bearing plate is fixedly installed at the bottom end of the adjustment groove. Through holes are opened on both inner walls of the adjustment groove. The moving wheels can promote the smoothness of movement when the adjustment box moves.

When the rotating gear rotates, it interlaces with adjusting tooth plates on both sides to generate a driving force, so that the two groups of adjusting tooth plates can move in opposite directions, thereby driving the adjusting boxes on both sides to move in the opposite directions. The adjusting boxes drive the spraying nozzle to move accordingly, so as to facilitate the adjustment of the smoke spraying range and thus improve the effect of work efficiency.
[0016] The utility model provides a fire smoke simulation device for fire fighting. By setting a limit plate, during the adjustment and movement process, an adjustment box drives the limit plates on both sides to follow the movement, so that the other end of the limit plate drives a sliding block to slide inside the limit groove, which can limit the movement of the adjustment box, prevent position deviation, and promote the stability of range adjustment.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model. Embodiment
[0024] As Figures 1-5 shown, the present utility model provides a fire smoke simulation device for fire fighting, including a main body 1 of the fire smoke simulation device. The main body 1 of the fire smoke simulation device includes a simulation box 2. An installation groove 3 is opened at the top of the simulation box 2, and a smoke generator 4 is fixedly installed inside the installation groove 3. Range adjustment units are arranged on both the left and right sides of the simulation box 2, and limiting units are arranged on both the front and rear sides of the simulation box 2. The limiting unit includes a limiting groove 212 opened at the bottom end of the front and rear outer shells of the simulation box 2. Connecting rods 213 are fixedly installed on the outer surfaces of the left and right sides of the simulation box 2 in front of the adjustment box 22. A limiting plate 214 is fixedly installed at the other end of the connecting rod 213, and a slide block 215 is fixedly installed at the other end of the limiting plate 214. The slide block 215 is slidably connected inside the limiting groove 212.
[0025] Furthermore, during the process of adjustment and movement, the adjustment box 22 drives the limiting plates 214 on both sides to move accordingly, so that the other end of the limiting plate 214 drives the slide block 215 to slide inside the limiting groove 212, which can limit the movement of the adjustment box 22 and prevent position deviation. Embodiment
[0026] As Figures 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the range adjustment unit includes a storage chamber 21 opened inside the outer shell on both sides of the simulation box 2, and an adjustment box 22 is movably installed inside the storage chamber 21. A folding tube 25 is fixedly installed on the rear input end of the adjustment box 22, and the other end of the folding tube 25 passes through the inner shell of the storage chamber 21 and extends to the output end of the smoke generator 4. Moving wheels 24 are rotatably installed on both sides of the bottom end of the adjustment box 22, and a spray nozzle 23 is fixedly installed on the outer output end of the adjustment box 22. The bottom end of the simulation box 2 is opened inside the adjustment box 21. Slot 26, a bearing plate 27 is fixedly installed on the bottom end of the adjusting slot 26, through holes 28 are opened on the inner walls on both sides of the adjusting slot 26, a motor 29 is fixedly installed on the top of the bearing plate 27, a rotating gear 210 is fixedly installed on the output end of the motor 29, and adjusting tooth plates 211 are meshed and connected on the outer surfaces of both sides of the rotating gear 210, one end of the adjusting tooth plate 211 passes through the through hole 28 and extends on the inner outer surface of the adjusting box 22, and a piston limiting rod 216 is movably inserted inside the other end of the adjusting tooth plate 211, and the other end of the piston limiting rod 216 is fixedly installed on one inner wall of the adjusting slot 26.
[0027] Furthermore, the output end of the motor 29 drives the rotating gear 210 to rotate. When the rotating gear 210 rotates, it interlaces with the adjusting tooth plates 211 on both sides to generate a driving force, so that the two sets of adjusting tooth plates 211 can move in opposite directions, and then push the adjusting boxes 22 on both sides to move in the opposite direction. The adjusting boxes 22 drive the spray nozzle 23 to move, so as to adjust the smoke spraying range.
[0028] The following is a detailed description of the working principle of the fire smoke simulation equipment for fire fighting.
[0029] like Figures 1-5 As shown, when in use, the fire smoke simulation device body 1 is placed at the required position, the smoke generator 4 is started to generate smoke and transported to the inside of the adjustment box 22 through the folding tube 25, and then sprayed to the outside by the spray nozzle 23. When the spray range needs to be adjusted, the output end of the motor 29 drives the rotating gear 210 to rotate. When the rotating gear 210 rotates, it intersects with the adjusting tooth plates 211 on both sides to generate a driving force, so that the two sets of adjusting tooth plates 211 can move in the opposite direction, and then push the adjusting boxes 22 on both sides to move in the opposite direction. The adjusting box 22 drives the spray nozzle 23 to move, which is convenient for adjusting the smoke spray range. In the process of adjusting movement, the adjusting box 22 drives the limiting plates 214 on both sides to move, so that the other end of the limiting plate 214 drives the slider 215 to slide in the limiting groove 212, which can limit the movement of the adjusting box 22 to prevent position deviation.
[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and concept of the present utility model fall within the protection scope of the present utility model.
