[0026] The utility model is further described in detail below in connection with the drawings and examples.

[0027] As Figures 1-2 Indicated, the utility model provides a kind of open pit mine safety cabin, comprising: shell 1, cabin 2, hatch, cabin 2 is located in shell 1, hatch is sealed and is set on shell 1;Skeleton 3 is set in cabin 2, skeleton 3 is fixedly connected with shell 1, shockproof protective layer 4 is arranged between skeleton 3 and shell 1, seat is set on skeleton 3, and seat is provided with safety belt.

[0028] Shell 1 is ellipsoid, and skeleton 3 is ellipsoid reinforced skeleton, which supports shell 1 through skeleton 3 and improves the safety performance of safety cabin shell 1.

[0029] Safety cabin forms layered structure through shell 1, skeleton 3 and shockproof protective layer 4, which provides support for shell 1 and provides effective buffering and damping effect for cabin 2.

[0030] In a specific embodiment, the shape of safety cabin shell 1 is similar to that of an egg-shaped ellipsoid, with a length (major axis) of 4 m and a height (minor axis) of 2.35 m. Shell 1 includes a large head side and a small head side, and the hatch is sealingly arranged on the large head side of shell 1. A second door is sealingly arranged on the inside of the hatch corresponding to the position of skeleton 3.

[0031] In a specific embodiment, the distance between skeleton 3 and shell 1 is 0.1 m. Shell 1 includes two half-shells, which are fixedly connected to form a whole shell 1 by welding. The joint of the two half-shells is provided with a tray and a support rod, which are fixedly connected to the skeleton 3 by welding.

[0032] In a specific embodiment, the safety cabin shell 1 and reinforced skeleton 3 are made of high-strength Q345 steel to meet the application scenarios and requirements of the safety cabin. The safety cabin shell 1 is made of 12 mm thick plate material, and the ellipsoid left and right two half-shells are made by grinding tool to ensure the integrity of the cabin 2. The welding method is used in the installation process to form the whole shell 1 from the left and right two half-shells. The safety cabin reinforced skeleton 3 is made of square hollow steel pipe with a specification of 80x80mm and a thickness of 80mm. The outer side support plate has a specification of 100x100mm and a thickness of 10mm, and is connected to the shell 1 by welding. The shockproof protective layer 4 is a polystyrene foam material filled between the shell 1 and the reinforced skeleton 3, which is continuously and uniformly sprayed to play a noise-proof and shock-absorbing role, reducing the harm to the people seeking refuge in the process of collision between rock mass and safety cabin.

[0033] In one specific embodiment, the safety cabin door and the outer shell 1 are connected by a downward sliding mechanism, which facilitates quick closure by personnel seeking refuge. Rubber sealing strips are installed at the door seams to prevent harmful gases, dust, and water from entering the cabin 2. A second door, housed in the steel frame 3, is also equipped with sealing facilities, providing double protection.

[0034] In one specific embodiment, the seats are fixed to the steel frame 3, located 0.2m inside the second door, arranged symmetrically in two rows, each 0.5m high and 0.5m wide, providing a total of 12 seats to accommodate 12 people simultaneously for evacuation. Each seat is equipped with a double safety belt: a soft inner belt and a rigid outer belt. The rigid belt secures the evacuees, preventing injury from swaying during the rotation of the cabin 2; the soft belt protects occupants after the cabin 2 has stabilized, protecting them from sideways or downward movement caused by the cabin 2's rotation. The seats also have a rotating function, allowing for multi-angle adjustment to accommodate cabin 2 rotation.

[0035] In one specific embodiment, the cabin 2 is equipped with an oxygen self-rescue device, bottled water, food, and other necessities. The self-rescue device is placed above the seats for easy access after entry; other necessities are placed in a metal cabinet between the two rows of seats. A simple enclosed toilet is provided on the "narrow end" side of cabin 2 to prevent waste from spilling out due to cabin 2's rotation, ensuring air quality and personnel comfort within cabin 2. Fixed oxygen cylinders are installed and secured externally to handle prolonged rescue operations.

[0036] In one specific implementation, a communication base station is installed inside cabin 2, allowing personnel to access the open-pit mine's BeiDou digital system via a tablet computer within cabin 2. The digital system now provides full coverage of personnel and equipment positioning and panoramic video within the mining area. By viewing the real-time situation outside the safety cabin and the rescue site through all video surveillance in the open-pit mine, the anxiety of personnel seeking refuge is reduced.

[0037] In one specific implementation, a positioning system is installed inside the cabin 2. Through effective linkage with personnel positioning, it can provide accurate location for rescue and provide the necessary conditions for scientific rescue.

[0038] In one specific embodiment, the seat armrests are equipped with earplugs to reduce the noise damage to the hearing of the personnel taking refuge during the impact; the cabin is equipped with four batteries (12V, 120Ah), and an inverter that converts DC 12V to AC 220V with a power of 1000W to ensure the use of the cabin's lighting facilities and electronic equipment; underwater safety emergency equipment is provided to prevent damage to the cabin 2 from causing water to rush into the cabin 2.

[0039] like Figure 3As shown, in the case of landslide, the safe cabin moves towards the advancing side of the landslide by the kinetic energy of the falling rock, that is, moves to the working side of the stope, which can reduce the subsequent rescue excavation engineering quantity and facilitate the implementation of the later rescue.

[0040] The safe cabin rotates under the impact of the falling rock, and the emergency risks of the personnel in distress are solved by the reasonable layout in the cabin 2. After the release of the landslide energy, the rescue period is entered, and the physiological needs of the personnel in distress are ensured by the layout of the life necessities, simple closed toilet and other equipment and facilities in the cabin 2, so as to provide favorable conditions for the rescue.

[0041] The overall idea of the safe cabin design is constructed by the external shape, internal structure, emergency response in distress, convenient rescue and the whole process of guaranteeing the safety of the personnel in distress.

[0042] The utility model has been described in detail in combination with the drawings and the embodiments, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model. The contents not described in detail in the utility model can adopt the prior art.
