Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake simulation equipment and relates to a fire-fighting earthquake simulation experience platform. Background Art

[0002] In order to reduce casualties caused by earthquakes, people can organize earthquake drills to train and increase their ability to respond when an earthquake occurs.

[0003] The main cause of casualties caused by earthquakes is the collapse of buildings. During an earthquake, the shaking of the ground causes inconvenience to walking and affects the escape of people in the building. Therefore, existing earthquake training equipment often simulates ground vibration to train people's walking ability under vibration. For example, an earthquake simulation platform system with publication number CN214226284U, when used, places a house model on a flat plate, and by rotating the first crankshaft, the longitudinal vibration block can be made to slide vertically up and down on the shell through the transmission mechanism, so that the flat plate mounted on the longitudinal vibration block can vibrate up and down to simulate the influence of the longitudinal earthquake wave on the ground when an earthquake occurs.

[0004] However, when an earthquake strikes, people in low-rise buildings often need to escape through stairs, but the training in existing technologies often involves walking on flat ground. Therefore, the scene simulation during the training process is not comprehensive enough and the training effect needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-8 As shown, the utility model provides a fire earthquake simulation experience platform, including a box fire truck 1, wherein two symmetrical fixed plates 5 are arranged inside the compartment 101 of the box fire truck 1, and the fixed plates 5 are inclined relative to the bottom of the compartment 101, and four pulleys 7 are arranged on the side close to the fixed plates 5, and the two pulleys 7 on the same side are connected by a belt 8. A connecting shaft 9 is rotatably connected between the two fixed plates 5, and the two ends of the connecting shaft 9 are respectively fixedly connected to the pulleys 7 at corresponding positions on the two fixed plates 5, so that the two belts 8 run synchronously, and a motor 13 is fixedly arranged on the other side of one of the fixed plates 5, and the output shaft of the motor 13 passes through the fixed plate 5 and is fixedly connected to one of the pulleys 7 on the fixed plate 5. A plurality of fixed blocks 10 are fixedly arranged at the outer end of the belt 8, and the fixed blocks 10 on the two belts 8 correspond to each other, and a pedal assembly 14 is arranged between the corresponding two fixed blocks 10.

[0027] The experiencer enters the interior of the carriage 101 through the door of the carriage 101. The pedal assembly 14 is arranged in a step-like manner inside the carriage 101, so the experiencer can step on the top of the pedal assembly 14 to simulate the situation of going down the stairs: at this time, the motor 13 is turned on, and the motor 13 drives the pulley 7 to rotate and causes the belt 8 to start moving. Under the connection of the connecting shaft 9, the two belts 8 move synchronously and drive the pedal assembly 14 to move. The pedal assembly 14 on the belt 8 moves upward, and the pedal assembly 14 under the belt 8 moves downward, and this cycle is repeated, so that although the experiencer steps on the top of the pedal assembly 14 and moves downward, the pedal assembly 14 moves upward at the same time, that is, the experiencer is actually stationary relative to the ground and can always move on the pedal assembly; in the process of simulating going down the stairs, the box fire truck 1 and the carriage 101 simultaneously simulate the vibration of the earthquake. The combination of the two can simulate the situation of escaping through the stairs during the earthquake, making the simulated scene more comprehensive. During fire training, the training effect is also improved.

[0028] In some embodiments, Figure 3 , 5 As shown, the pedal assembly 14 includes a crossbeam 1404, and the two ends of the crossbeam 1404 are respectively fixedly connected to two corresponding fixing blocks 10, so that the belt 8 can drive the pedal assembly 14 to operate. The outer end of the crossbeam 1404 is sleeved with a mounting seat 1403, and the bottom end of the mounting seat 1403 is provided with a first fastening bolt through a thread. The top of the mounting seat 1403 is fixedly provided with a pedal body 1401, and the pedal body 1401 needs to be kept as horizontal as possible relative to the ground during operation. The top of the pedal body 1401 is fixedly provided with an anti-skid pad 1402 that plays an anti-skid role. During the simulation, the experiencer steps on the top of the anti-slip pad 1402 on the pedal body 1401, so the pedal body 1401 and the anti-slip pad 1402 are used to simulate the steps of the stairs. Before the simulation, the mounting base 1403 is rotated at the outer end of the beam 1404 to drive the pedal body 1401 to rotate, so as to adjust the angle of the pedal body 1401. After adjustment, tighten the first fastening bolt. Before the experience, keep the pedal body 1401 as horizontal as possible to improve the safety during the simulation.

[0029] In order to maintain stability, Figure 2~Figure 4 As shown, a plurality of support wheels 11 are provided on the inner side of the belt 8, and the inner side of the belt 8 is stuck in the recess of the support wheel 11, and the support wheel 11 is movably connected to the corresponding fixed plate 5 through a rotating shaft. A fixed shaft 15 is fixedly provided on the side of the fixed plate 5 facing the inner wall of the carriage 101, and one end of the fixed shaft 15 is movably connected to the inner wall of the carriage 101 through a rotating shaft, and the fixed shaft 15 is provided at the lower end of the fixed plate 5. A support arm 3 is hinged below the fixed plate 5, and the support arm 3 is provided at the higher end of the fixed plate 5. A linear motor 12 is provided at the bottom end of the support arm 3, and the linear motor 12 is fixed at the bottom end of the carriage 101, and the bottom end of the support arm 3 is hinged to the mover of the linear motor 12.

[0030] By arranging a support wheel 11 on the inner side of the belt 8, the support wheel 11 can support the belt 8 from the inside. Even if the belt 8 bears the weight of the pedal assembly 14 and the experiencer, under the support of the support wheel 11, the belt 8 will not sink downward and deform. Before the simulation experience, the mover of the linear motor 12 moves, thereby driving the support arm 3 to move. The support arm 3 can drive the higher end of the fixed plate 5 to move, and the lower end of the fixed plate 5 rotates around the fixed axis 15, so as to adjust the inclination angle of the fixed plate 5, thereby simulating stairs at different angles and improving the simulation range.

[0031] During the simulation process, ensure safety as much as possible, such as Figure 2 , 8 As shown, a handrail 4 is fixedly provided on the top of the fixed plate 5, a protective component 6 is provided inside the carriage 101, and the fixed plate 5 is located below the protective component 6; the protective component 6 includes a waist belt 601, and two safety ropes 602 are fixedly provided on the top of the waist belt 601. The top of the safety rope 602 is movably connected to the top of the interior of the carriage 101 through a slide rail, so that the waist belt 601 is fixed to the waist to play a protective role.

[0032] During the simulation training, the experiencer fixes the belt 601 around his waist, and the belt 601 is connected to the top of the inside of the carriage 101 through the safety rope 602. Therefore, the experiencer can be indirectly fixed to the inner wall of the carriage 101 through the protection component 6 to prevent the experiencer from falling and getting injured during the simulation.

[0033] In some embodiments, Figure 1 , 6 As shown in , 7, a vibration mechanism 2 buried in the ground is provided at the bottom of the box fire truck 1, and the vibration mechanism 2 includes a fixed frame 201, and a plurality of rollers 202 are provided inside the fixed frame 201. Both ends of the rollers 202 are movably connected to the inner wall of the fixed frame 201 through a rotating shaft. The rollers 202 can contact the tires of the box fire truck 1, and a plurality of irregular protrusions are fixedly provided on the outer ends of the rollers 202. The protrusions make the box fire truck 1 bump and vibrate, thereby simulating an earthquake.

[0034] In some embodiments, a plurality of sleeves 203 are fixedly provided on the front side of the fixing frame 201, and an extension shaft 204 is fixedly provided on the front end of the drum 202. The extension shaft 204 corresponds to the sleeve 203 one by one, and one end of the extension shaft 204 extends to the inside of the corresponding sleeve 203. A second fastening bolt is threadedly provided on the top of the sleeve 203 to limit the rotation of the drum 202, so that the box-type fire truck 1 can be driven out from the top of the vibration mechanism 2.

[0035] The vibration mechanism 2 is buried in the ground as a whole. After tightening the second fastening bolt, the extension shaft 204 can be fixed and the rotation of the roller 202 can be restricted. At this time, the box fire truck 1 can be driven onto the top of the vibration mechanism 2 so that the tire of the box fire truck 1 contacts the roller 202. Then the second fastening bolt is loosened so that the roller 202 can rotate freely. Then, during the simulation process, the box fire truck 1 is driven to run on the top of the vibration mechanism 2. During the simulation process, the roller 202 rotates with the rotation of the tire of the box fire truck 1. Therefore, the box fire truck 1 runs in place on the top of the vibration mechanism 2. During the rolling of the roller 202, the irregular protrusions on the surface of the roller 202 cause the box fire truck 1 to vibrate and bump during operation, thereby simulating the vibration of an earthquake.

[0036] In addition, the experiencer can also stand in the carriage 101 and use the protection component 6 for protection as needed to experience the feeling of walking on flat ground during an earthquake.

[0037] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
