A mine explosion-proof compressed oxygen self-rescue device

Abstract

This utility model discloses a mine explosion-proof compressed oxygen self-rescue device, including a shell and a cover. The shell houses a breathing mechanism and a compressed oxygen tank. A winding chamber is located at the bottom of the shell, with a winding reel rotatably mounted inside. A rope passage opening is provided on the rear wall of the winding chamber. A support is located at the bottom rear side of the shell, with a pulley rotatably mounted on the support. A guide plate is located at the top rear side of the shell, with a through hole on its surface. A connecting block is located at the bottom rear side of the cover. A traction rope is wound onto the winding reel. One end of the traction rope passes through the rope passage opening, wraps around the pulley, passes through the through hole, and connects to the connecting block. This utility model, by providing a traction rope between the shell and the cover, allows for easy recycling of the cover. During use, the cover is opened and discarded. After use, rotating the winding reel winds the traction rope, allowing the cover to be retrieved by pulling the traction rope. This facilitates the recycling of the cover, prevents loss, reduces resource waste, and lowers operating costs.

Description

Technical Field

[0001] This utility model relates to the field of self-rescue device technology, specifically to a mine explosion-proof compressed oxygen self-rescue device. Background Technology

[0002] The mine explosion-proof compressed oxygen self-rescue device is a personal portable respiratory protection and escape device specifically designed for underground miners. Its core function is to provide the wearer with clean and reliable breathing oxygen when disasters occur in the mine (such as gas explosions, coal dust explosions, fires, or roadway collapses that cause oxygen deficiency or the presence of toxic or harmful gases in the ambient air), enabling the wearer to safely evacuate the danger zone and achieve self-rescue in hazardous atmospheric environments.

[0003] A compressed oxygen self-rescue device consists of a shell and a cover. When in use, the cover is opened and the breathing mechanism in the shell is worn for assisted breathing, such as the isolated compressed oxygen self-rescue device proposed in patent application number "201620021545.5".

[0004] In the existing technology, when using a compressed oxygen self-rescue device, the breathing mechanism inside the shell needs to be manually put on after opening the cover. It is inconvenient to operate if the cover is held manually. Therefore, the cover is usually discarded after opening. However, the discarded cover is not only inconvenient to recycle and reuse, causing waste, but it is also easy to lose.

[0005] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0006] The present invention provides a mine explosion-proof compressed oxygen self-rescue device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mine explosion-proof compressed oxygen self-rescue device includes a shell and a cover. The shell contains a breathing mechanism and a compressed oxygen tank. The bottom of the shell has a winding chamber with a winding reel rotatably mounted inside. The rear wall of the winding chamber has a rope passage opening. The bottom rear side of the shell has a support with a pulley rotatably mounted on the support. The top rear side of the shell has a guide plate with a through hole on its surface. The bottom rear side of the cover has a connecting block. A traction rope is wound on the winding reel. One end of the traction rope passes through the rope passage opening, goes around the pulley, passes through the through hole, and connects to the connecting block.

[0009] Preferably, the outer ring of the bracket is provided with a limiting ring.

[0010] Preferably, a cover plate is provided at the bottom opening of the winding cavity, a rotating shaft is provided at the center of the winding reel, and a crank handle is provided at the bottom end of the rotating shaft through the cover plate.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the explosion-proof compressed oxygen self-rescue device for mining provided by this utility model embodiment have at least one of the following technical effects:

[0013] This utility model, through the above-mentioned technical solution, provides a traction rope between the shell and the cover. When in use, the cover is first opened and discarded aside, at which point the traction rope is pulled out from the winding reel. After use, the traction rope is wound back onto the winding reel by rotating it, and the cover is pulled by the traction rope for recycling. This facilitates the recycling of the cover, avoids loss of the cover, reduces resource waste, and reduces usage costs. Attached Figure Description

[0024] like Figure 1-4 The diagram shown is a structural schematic of a preferred embodiment of the present invention: a mine explosion-proof compressed oxygen self-rescue device.

[0025] In this embodiment, the device includes a housing 1 and a cover 2. The housing 1 contains a breathing mechanism 3 and a compressed oxygen tank 4. The bottom of the housing 1 has a winding cavity 5, which is a circular cavity structure. A winding reel 6 is rotatably mounted inside the winding cavity 5. A rope passage 7 is opened on the rear wall of the winding cavity 5. A support 8 is provided at the bottom rear side of the housing 1, and a pulley 9 is rotatably mounted on the support 8. A guide plate 10 is provided at the top rear side of the housing 1, and a through hole 11 is opened on the surface of the guide plate 10. A connecting block 12 is provided at the bottom rear side of the cover 2. A traction rope 13 is wound onto the winding reel 6, and one end of the traction rope 13 passes through the through hole 7. After the rope opening 7 passes through the pulley 9 and through the through hole 11, it connects to the connecting block 12. The rope opening 7 is used to pass the traction rope 13, and the guide plate 10 is used to position and guide the traction rope 13. When in use, the cover 2 is first opened and discarded aside. At that time, the traction rope 13 is pulled out from the winding reel 6. After use, the winding reel 5 is rotated by turning the rocker handle 17. The rotation of the winding reel 5 causes the traction rope 13 to be wound back onto the winding reel 5. The cover 2 is pulled by the traction rope 13 for recycling, which facilitates the recycling of the cover 2, avoids the loss of the cover 2, reduces resource waste, and reduces the cost of use.

[0026] In this embodiment, the outer ring of the bracket 8 is provided with a limiting ring 14, which limits the traction rope 13 to the pulley 9 to prevent the traction rope 13 from slipping off the pulley 9.

[0027] In this embodiment, a cover plate 15 is provided at the bottom opening of the winding cavity 5, and a rotating shaft 16 is provided at the center of the winding reel 6. A crank handle 17 is provided at the bottom end of the rotating shaft 16 through the cover plate 15. By turning the crank handle 17, the winding reel 6 can be rotated to wind up the traction rope 13.

[0028] The present invention relates to a mine explosion-proof compressed oxygen self-rescue device. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0029] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
