Description

Technical Field

[0001] The invention relates to a protection device, in particular to a protection device for earthquake simulation. Background Art

[0002] Earthquakes, also known as ground motions or seismic vibrations, are natural phenomena caused by the rapid release of energy from the earth's crust, which produces seismic waves. The plates on the earth squeeze and collide with each other, causing displacement and rupture at the edges and inside the plates, which is the main cause of earthquakes. The teaching of earthquake knowledge often uses pictures and videos to show the reactions and hazards of earthquakes. However, in the process of teaching children, it is necessary to give children a personal experience, and at the same time, it is necessary to demonstrate the changes of real objects under different vibration changes. However, when conducting earthquake simulations, it is impossible to guarantee whether objects will collapse during vibration. In this way, there are great hidden dangers to the safety of children.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1

[0031] A protective device for earthquake simulation, such as Figure 1-5 As shown, it includes a frame 1, a rotating block 2, a pulling mechanism 3 and an anti-vibration mechanism 4. The rotating block 2 is symmetrically rotated on the upper part of the frame 1, the pulling mechanism 3 is connected between the frame 1 and the rotating block 2, and the anti-vibration mechanism 4 is provided at the bottom of the frame 1.

[0032] The pulling mechanism 3 includes a first fixed block 31, a first rotating rod 32, a rotating wheel 33, a second rotating rod 34, a second fixed block 35 and a rope 36. The first fixed block 31 is provided at the top inner portion of the left side of the frame 1. The first rotating rod 32 is rotatably provided on the upper right side of the first fixed block 31. The second rotating rod 34 is rotatably provided on the lower right side of the first fixed block 31. The right side of the second rotating rod 34 and the right side of the first rotating rod 32 are both provided with rotating wheels 33. The second fixed block 35 is symmetrically provided front and back on the lower left side of the frame 1. A rope 36 is connected between the upper rotating wheel 33 and the left front side of the front rotating block 2. A rope 36 is also connected between the lower rotating wheel 33 and the left rear side of the rear rotating block 2. The ropes 36 all pass through the first fixed block 31 and the second fixed block 35 on the same side.

[0033] The anti-vibration mechanism 4 includes a first spring 41, a connecting block 42, a third fixed block 43, a movable column 44 and a second spring 45. A plurality of first springs 41 are provided at the bottom of the rotating block 2, a connecting block 42 is provided between the bottoms of the first springs 41 on the same side, third fixed blocks 43 are symmetrically provided front and back on the left and right sides of the bottom of the frame 1, a movable column 44 is slidably provided inside the third fixed block 43, and a second spring 45 is connected between the top of the movable column 44 and the third fixed block 43 on the same side.

[0034] When people start to simulate an earthquake, they lie in the frame 1. Due to gravity, the frame 1 moves downward, driving the third fixed block 43 to move downward. At this time, the second spring 45 is compressed, and the second spring 45 plays a buffering role. After people lie in the frame 1, they manually rotate the wheel 33, and the wheel 33 drives the first rotating rod 32 and the second rotating rod 34 to rotate. At the same time, the pull rope is tightened. The pull rope drives the rotating block 2 and the connecting block 42 to rotate to protect people. During an earthquake, the device vibrates, and the connecting block 42 and the first spring 41 can play a buffering role to reduce the impact of the earthquake on people, so that the protection effect is better.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, it also includes a loading mechanism 5, which includes a second moving block 51, a loading frame 52 and a third spring 53. The second moving block 51 is slidably provided on the right side of the frame 1, and the loading frame 52 is slidably provided on the right side of the frame 1 front and back, and the lower side of the loading frame 52 is connected to the frame 1 with a third spring 53.

[0037] It also includes a transmission mechanism 6, which includes a motor 61, a fourth fixed block 62, a first bevel gear 63, a third rotating rod 64, a first gear 65 and a rack 66.

The first gear 65 is provided on the lower side of the third rotating rod 64. A rack 66 is provided on the top of the second moving block 51, and the rack 66 cooperates with the first gear 65.

[0038] Before the earthquake simulation, the motor 61 is started, and the output shaft of the motor 61 drives the first bevel gear 63 to rotate, and then drives the third rotating rod 64 to rotate, and the third rotating rod 64 drives the first gear 65 to rotate and then drives the rack 66 to move to the left, so that the rack 66 drives the second moving block 51 to move to the left, and people pull out the loading frame 52. At this time, the third spring 53 is compressed, and people put food and water into the loading frame 52, and then release the loading frame 52. At this time, the third spring 53 is reset, driving the loading frame 52 to reset, and then the motor 61 is controlled to reverse, so that the first bevel gear 63, the third rotating rod 64, and the second moving block 51 are reset. After the earthquake simulation starts, people can survive with the food and water in the loading frame 52 and wait for rescue, making the earthquake simulation more realistic.

[0039] It also includes an alarm mechanism 7, which includes an alarm 71, a switch 72, a fifth fixed block 73 and a third movable block 74. The alarm 71 is symmetrically arranged on the front and back of the lower left side of the frame 1, and the switch 72 is slidably arranged inside the alarm 71. A fifth fixed block 73 is arranged on the upper right side of the frame 1, and the fifth fixed block 73 is located above the fourth fixed block 62. A third movable block 74 is slidably arranged on the left side of the fifth fixed block 73, and the left side of the third movable block 74 is connected to the switch 72.

[0040] When the second movable block 51 moves to the left until it contacts the fifth fixed block 73, it drives the third movable block 74 to move to the left. At this time, the elastic member is stretched, and the third movable block 74 drives the switch 72 to move to the left, so that the alarm 71 is turned on. The alarm 71 reminds people that the second movable block 51 has been turned on. People control the second movable block 51 to stop moving, which makes it convenient for people to take out the food and send a distress signal to the rescuers.

Transmission wheels are provided on the upper part of the fourth rotating rod 81 and the middle part of the third rotating rod 64, and a belt 82 is wound around the transmission wheels. The lower side of the fourth rotating rod 81 and the middle part of the second rotating rod 34 are connected with the second bevel gear 83, and the two second bevel gears 83 are meshed with each other. A second gear 84 is provided on the right side of the second rotating rod 34, and a third gear 85 is provided on the left side of the first rotating rod 32. The second gear 84 and the third gear 85 are meshed with each other.

[0042] After people lie down inside the frame 1, the motor 61 is started, and the output shaft of the motor 61 drives the third rotating rod 64 to rotate, which in turn drives the transmission wheel and the belt 82 to rotate, and then drives the fourth rotating rod 81 to rotate, and the fourth rotating rod 81 drives the second bevel gear 83 to rotate, and then drives the second rotating rod 34 to rotate, and the second rotating rod 34 drives the second gear 84 and the third gear 85 to rotate, and then drives the first rotating rod 32 to rotate, and the first rotating rod 32 and the second rotating rod 34 drive the rotating wheel 33 to rotate, so that the rotating wheel 33 drives the above components to operate, so that the rotating block 2 is closed, so that people do not need to operate manually.
