[0062] On the top of the middle cabin 2, there is a photovoltaic panel 5, which forms a certain irradiation angle, and the total power is not less than 3.5kW. The photovoltaic panel 5 is electrically connected to the shelter electrical system and mechanical and electrical equipment.

[0063] The middle cabin 2 includes a main cabin body 22. On both sides of the main cabin body 22, a left extended cabin 21 and a right extended cabin 23 are respectively movably arranged through an extension mechanism 9. The shelter adopts an extension structure of one expanding into two. The cabin bodies can respectively expand to the left and right sides to form the left extended cabin 21 and the right extended cabin 23. The left extended cabin 21 and the right extended cabin 23 are symmetrically arranged with respect to the main cabin body 22. The left extended cabin 21 and the right extended cabin 23 are respectively protected by a protection device 10.

[0064] As Figure 4 shown, the middle cabin floor is divided into a fixed floor 24 and a folding floor 25. Each set of folding floor 25 is composed of two movable floors. The movable floors are connected to the fixed floor 24 through hinges. When performing the folding action, the bottom extension mechanism automatically lifts the movable floors into a small angle, and the fixed floor 24 moves to fold the movable floors in place. This part of the structure is configured in cooperation with the extended cabin in the extended and folded states, which belongs to the prior art and will not be elaborated here. The fixed floor 24 has a graphene heating function. The structure from bottom to top is a honeycomb aluminum substrate, a thermal insulation layer, a reflective film, a graphene heating plate, and a floor layer.

[0065] Among them, as Figure 5 、 6 shown, the extension mechanism 9 includes a slide rail 93. Chutes are respectively arranged on both sides of the main cabin body 22. The slide rail 93 is slidably arranged in the corresponding chute. A rack 91 that cooperates with it is connected below the slide rail 93. The rack 91 slides in the chute together with the slide rail 93. A gear 92 is meshed and connected below the rack 91. The gear 92 is driven by a servo motor, and the servo motor is arranged at the bottom of the rear cabin 3; the upper part of the slide rail 93 is connected to the bottom of the corresponding left extended cabin 21 or right extended cabin 23.

[0066] When extension is required, the servo motor drives the gear 92 to rotate. The gear 92 drives the engaged rack 91 to move left and right in the chute, thereby further driving the left extended cabin 21 or the right extended cabin 23 to move, so as to realize the extension and folding of the left extended cabin 21 or the right extended cabin 23.

[0067] Furthermore, the protection device 10 includes a fixed plate. The fixed plate is arranged on the main cabin body 22. A sleeve 101 and an electric cylinder 103 are arranged on the fixed plate. A safety pin 102 movably penetrates through the sleeve 101. The safety pin 102 is controlled to move by the electric cylinder 103. Two through holes that cooperate with the safety pin 102 are opened on the chute wall of the main cabin body 22. The safety pin 102 penetrates through any one of the through holes and contacts the slide rail 93.

[0068] To enhance safety, a safety pin 102 is set. The safety pin 102 is linearly reciprocally driven by an electric cylinder 103. Cooperating with the through holes in the extended and retracted states on the transmission slide rail 93, it further limits and fixes the slide rail 93, achieving secondary safety protection for the expansion mechanism 9.

[0069] The main cabin is a multi-functional area for team meetings, daily office work, etc. On the inner wall of the main cabin 22 close to the front cabin 1, there are respectively a public information display screen 221 and a centralized control liquid crystal screen 222. The centralized control liquid crystal screen 222 realizes comprehensive monitoring and management of the electrical system, electromechanical equipment, and environmental parameters of the entire shelter through a PLC. Inside the main cabin 22, on the side of the centralized control liquid crystal screen 222, there is also a rack cabinet 223 for rack pulling, hardware maintenance, storage, etc.; on the inner wall of the main cabin 22 far from the front cabin 1, there is a large-screen conference all-in-one machine 224, which adopts a folding design for easy maintenance; in the middle part of the main cabin 22, there are conference desks and chairs 225. On the right side of the desktop, multiple sets of hidden screens, keyboards, mice, multi-functional information boxes, omnidirectional microphones, etc. are arranged for meetings.

[0070] The left expansion cabin 21 is an operation area for unit control, data acquisition, video monitoring, etc. At one end of the left expansion cabin 21, there is an emergency escape door 211. On the side wall of the left expansion cabin 21 far from the main cabin 22, there are respectively several display screens 212 and an operation display screen 213. The operation display screen 213 is located below the display screen 212, with two rows of display screens configured, and the installation angle conforms to ergonomics. In the upper row, multiple large data display screens 212 are set for the rear personnel to view monitoring-related content; in the lower row is the operation display screen 213, configured with an industrial control computer, keyboard, mouse, and multi-functional interface panel for the staff to use.

[0071] The right expansion cabin 23 is a supervision area for temporary rest, storage, etc. Inside the right expansion cabin 23, there is a storage sofa seat box 232. On the side wall of the right expansion cabin 23 far from the main cabin 22, there are respectively a daylighting window 233 and a storage wall cabinet 234. On the side wall of the right expansion cabin 23, there is a main access door 231, and the main access door 231 and the emergency escape door 211 are diagonally arranged.

[0072] All facilities in the middle cabin 2 are fixedly installed, and the seats need to be fixed to the edge of the desktop during the expansion and contraction process of the cabin. The floor of the middle cabin 2 is divided into a fixed floor 24 and a folding floor 25. Each set of folding floor 25 consists of two movable floors, and the movable floors are connected to the fixed floor 24 through hinges. When the expansion cabin is retracted, the bottom expansion mechanism automatically lifts the movable floor at a small angle, and then the fixed floor 24 of the expansion cabin folds the movable floor in place to achieve the retraction of the shelter.

[0073] The middle cabin 2 is the main working area for the staff. For the display of public information in the cabin and the convenience of communication between workstations, while ensuring sufficient activity space for personnel, the overall layout of the cabin is designed longitudinally in three rows, with all personnel facing one side. One main access door 231 is provided at the front of the right extended cabin 23, and one emergency escape door 211 is provided at the rear end of the left extended cabin 21. The two doors are arranged diagonally, and the door bodies are made of aluminum alloy skin doors.
