Description

Technical Field

[0001] This invention relates to the field of shelter technology, and more specifically to a temporary earthquake emergency protection device. Background Technology

[0002] In response to earthquakes, people often try to minimize the harm to human life and property by strengthening the seismic resistance of buildings and learning some earthquake emergency protection knowledge. However, such protective measures are still not effective in protecting people during earthquakes, and human lives inevitably face serious threats.

[0003] In the prior art, patent publication number CN101638946A discloses a disaster shelter, including an outer shell and an inner shell. The outer shell is spaced outside the inner shell, and elastic devices are provided between each surface of the outer and inner shells. Entrances are correspondingly opened on the front of the outer and inner shells, and matching door panels are provided on the entrances. The disaster shelter is also equipped with survival necessities. Because the elastic devices between the outer and inner walls provide a buffer against impacts, and both the outer and inner walls are made of high-strength, fire-resistant, and lightweight materials, it can effectively protect people's lives during disasters (such as earthquakes, fires, and attacks by bandits). The included survival necessities allow people to call for help and sustain life when trapped. Furthermore, this example has a simple structure and is easy to use.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] The earthquake emergency temporary protection device provided in this embodiment can be used for temporary shelter of people during earthquake disasters.

[0039] like Figure 1The image shows a specific embodiment of the earthquake emergency temporary protective device provided in this example, comprising: a shell, the interior of which has a protective cavity for accommodating personnel. In use, personnel enter the protective cavity of the shell to avoid earthquake damage. To increase the rigidity of the shell, it can be constructed as a metal outer shell.

[0040] like Figure 1 As shown, the housing includes an upper housing 1 and a lower housing 2, which are connected by a rotating section 3. The rotating section 3 is horizontally rotatably connected to both the upper housing 1 and the lower housing 2. Specifically, the rotating section 3 can be annular, thus maintaining a sealed connection with the upper housing 1 and the lower housing 2 during rotation. A latching hole 4 can be provided on the outer wall of the rotating section 3, allowing an external person to insert their hand into the latching hole 4 to rotate the rotating section 3. The latching hole 4 design reduces the risk of damage and saves space during normal storage. Alternatively, as an alternative implementation, the latching hole 4 can be another handle structure, such as an outwardly protruding handle.

[0041] like Figure 1 As shown, the rotating section 3 is provided with an inlet 5 for accessing the protective cavity. When the inlet 5 is blocked, the rotating section 3 can be driven to reopen the inlet 5, ensuring that personnel can enter the protective cavity smoothly.

[0042] like Figure 1 As shown, in the earthquake emergency temporary protective device provided in this embodiment, both the upper shell 1 and the lower shell 2 are hemispherical structures, and the horizontal cross-section of the rotating section 3 is circular. This design improves the compressive strength of the shell and ensures personnel safety. Alternatively, as an alternative implementation, the upper shell 1 and the lower shell 2 can also be configured with other structures. For example, they can be cylindrical or conical structures.

[0043] like Figure 2 As shown, in the earthquake emergency temporary protection device provided in this embodiment, the lower housing 2 and the rotating section 3 are horizontally rotatably connected by a snap-fit ​​connection. Specifically, the lower housing 2 has a circumferentially arranged annular groove 6, and the rotating section 3 has a flange for snapping into the annular groove 6. During installation, the flange of the rotating section 3 is inserted into the annular groove 6, thereby achieving the snap-fit ​​connection between the rotating section 3 and the lower housing 2. When the rotating section 3 is rotated, the flange can slide within the annular groove 6, allowing the rotating section 3 to rotate independently. In addition, to improve the smoothness of the rotation of the rotating section 3, a roller can be provided between the contact surfaces of the lower housing 2 and the rotating section 3; or, a lubrication structure, such as a graphite sheet, can be provided between the contact surfaces.

[0044] like Figure 2 As shown, in the earthquake emergency temporary protection device provided in this embodiment, the upper shell 1 and the rotating section 3 are horizontally rotatably connected. To improve the smoothness of rotation of the rotating section 3 relative to the upper shell 1, rollers can be provided between the contact surfaces of the upper shell 1 and the rotating section 3; alternatively, other sliding structures, such as graphite sheets, can be provided between these contact surfaces. A support frame 7 is installed inside the upper shell 1, with its top horizontally rotatably connected to the upper shell 1 and its bottom fixedly connected to the rotating section 3. With this configuration, when the rotating section 3 rotates, the rotating section 3 and the support frame 7 rotate together. Since the support frame 7 is rotatably connected to the upper shell 1, the rotating section 3 can rotate independently relative to the upper shell 1, thereby reducing the rotational resistance of the rotating section 3. Specifically, the support frame 7 can be an arc-shaped structure adapted to the inner wall of the upper shell 1, and the top of the support frame 7 can be connected to the upper shell 1 by a hinge or a ball joint, etc.

[0045] like Figure 2 As shown, in the earthquake emergency temporary protective device provided in this embodiment, the upper shell 1 and the lower shell 2 include an inner layer 8 and an outer layer 9, with a shock-absorbing structure provided between the inner layer 8 and the outer layer 9. This shock-absorbing structure reduces external impacts and protects the safety of personnel inside. Alternatively, as an alternative implementation, either the upper shell 1 or the lower shell 2 can be configured as a single-layer structure.

[0046] like Figure 2 As shown, in the earthquake emergency temporary protective device provided in this embodiment, the shock-absorbing structure includes: a first shock-absorbing structure, which includes: a portal-shaped elastic friction plate 10 and a figure-eight elastic friction plate 11. The figure-eight elastic friction plate 11 is arranged opposite to the portal-shaped elastic friction plate 10. In use, the friction between the portal-shaped elastic friction plate 10 and the figure-eight elastic friction plate 11 reduces the impact force of the outer layer 9 on the inner layer 8. Furthermore, an outer pressure bow plate 12 is supported on the outer side of the figure-eight elastic friction plate 11. The symmetrical outer pressure bow plate 12 is used to further improve the supporting force of the figure-eight elastic friction plate 11.

[0047] like Figure 2 As shown, in the earthquake emergency temporary protection device provided in this embodiment, the damping structure further includes: a second damping structure, which is staggered with the first damping structure. The second damping structure includes: a plurality of damping springs 13 spaced apart, one end of the damping spring 13 abutting against the outer wall of the inner layer 8, and the other end of the damping spring 13 abutting against the inner wall of the outer layer 9.

[0048] like Figure 2 As shown in the illustration, the earthquake emergency temporary protective device provided in this embodiment includes a food compartment 14 and a water compartment 15 inside the protective cavity. The presence of these food compartments 14 and water compartments 15 extends the time personnel can wait for rescue inside the protective cavity, further ensuring personal safety.

[0049] like Figure 2 As shown, in the earthquake emergency temporary protection device provided in this embodiment, a suction pipe 16 is provided in the water tank 15. The suction pipe 16 is retractably and sealedly inserted into the water tank 15, and a manual water pump 17 is provided at the opening of the suction pipe 16. When the water level in the water tank 15 changes, the depth of the suction pipe 16 can be adjusted to ensure full utilization of water.

[0050] like Figure 2 As shown, the food compartment 14 has a door 18, which is opened and closed by rotating the door 18. This design reduces the encroachment on the protective cavity when opening and closing the door 18 of the food compartment 14, thus improving the convenience of operation.

[0051] like Figure 2 As shown, the protective cavity is equipped with a ventilation pipe 19 that communicates with the outside world. The ventilation pipe 19 ensures that the personnel inside can breathe normally.

[0052] like Figure 2 As shown, a wireless signal transmitter 20 is installed inside the protective cavity, and the wireless signal transmitter 20 is connected to the outside world through a spring wire 21; this setting ensures that the personnel inside can communicate smoothly with the outside world.

[0053] like Figure 2 As shown, a battery compartment 22 is provided at the bottom of the food compartment 14 and the water compartment 15. A battery is installed in the battery compartment 22, which can be used to provide lighting for the protective cavity and to power the wireless signal transmitter 20.

[0054] like Figure 2 As shown, the inlet 5 of the rotating section 3 is equipped with a switch door 23, which is rotatably mounted and has an opening elastic piece 24. When the switch door 23 is released from the lock between it and the rotating section 3, the switch door 23 can be automatically opened by the opening elastic piece 24.

[0055] The switch door 23 has an inwardly extending screw 25 inside, and the inlet 5 has a groove 26 for engaging the screw 25. A nut 27 is attached to the screw 25. When the door is closed, the screw 25 engages in the groove 26, and the switch door 23 is locked by tightening the nut 27. This design allows personnel inside the protective chamber to lock the switch door 23 from within the chamber, ensuring their safety.

[0056] It should be noted that, Figure 2 The structure shown is a schematic diagram of a specific embodiment of the earthquake emergency temporary protection device provided by the present invention. Therefore, Figure 2 The internal space of the protective device shown is also schematic. That is to say, the size of the internal space of the earthquake emergency temporary protective device provided by the present invention can be planned and set according to the actual situation to ensure that the refugees can move freely in the internal space; for example, in order to increase the height, the overall structure can be designed as an ellipse; in order to increase the width, the overall design can be made larger in diameter, etc.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
