Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas exploitation, and particularly to an intelligent expandable cabin used in oil and gas exploitation. Background Art

[0002] Based on the current general environment and trend of the booming development of "intelligent oil and gas fields" in China, the oil and gas industry is bound to move towards intelligence. As a key component of oil and gas fields, cabins serve as the command centers for oil and gas field exploitation and storage and transportation equipment in various stages such as exploration, drilling, well service, fracturing, oil (gas) production, gathering and transportation, and storage and transportation.

[0003] With the continuous progress of technology and the continuous expansion of operation scale, the requirements for command and control systems in oil and gas field exploitation and storage and transportation are becoming increasingly strict. The command cabin should be able to carry a large number of professional equipment and technical personnel to ensure efficient and stable operation in complex and changeable working environments. The cabin is equipped with instruments for controlling and operating the process of oil and gas field exploitation and storage and transportation, as well as data servers, industrial control computers, network switches, etc. for data processing, and also includes conference tables, office chairs, display screens, etc. for realizing central command in oil and gas field exploitation and storage, and also includes heating, ventilation and other equipment for providing a working environment for various instruments. Therefore, sufficient office space should be reserved inside the cabin.

[0004] Traditional fixed command cabins only consider the spatial layout in the use state, and all use disassembled parts to be assembled on site. For oil and gas exploitation command, it may be necessary to move according to the change of exploitation location and find suitable exploitation points in different regions. In order to facilitate direct control of exploitation equipment, as the command center, the cabin also often moves. However, for fixed command cabins, they can only be disassembled and reassembled for use. But this method not only increases the transportation, installation and subsequent maintenance costs of fixed cabins, but also is difficult to meet the requirements of rapid deployment and flexible adjustment in remote and inaccessible oil and gas field areas.

[0005] To overcome these challenges, cabins with unfolding and folding functions have emerged. Such cabins are compactly folded in the transportation state to reduce space occupation; during operation, the cabins are unfolded to provide a spacious and comfortable working space. For example, the pull-type linkage expandable cabin of patent "CN2786025Y" consists of two side expandable cabins and a fixed-width fixed cabin. The two side expandable cabins are unfolded and folded through the telescopic mechanism at the bottom of the fixed cabin. Since relative displacement occurs between the expandable cabins and the fixed cabin, the air outlets for air conditioning in general cabins are set on the top of the fixed cabin, which results in that after the cabin is folded, the top surface of the expandable cabin completely blocks the air outlets, making the air conditioning system of the cabin unable to play an obvious role even when it is turned on before the expandable cabin is fully expanded.

[0006] If the working environment of oil and gas extraction is in a plateau area, the temperature in the plateau area is around -30℃ all year round, which makes it impossible to start electrical equipment that is not resistant to low temperatures. In addition, the conventional position sensor is used to feedback the expansion distance of the expansion cabin. Due to the low temperature, the sensor accuracy decreases or the signal cannot be fed back. As a result, the traditional position sensor feedback method of cabin expansion cannot play the role of intelligent expansion of the cabin under low temperature conditions. Summary of the invention

[0007] The present invention is intended to provide an intelligent expansion cabin for oil and gas production, so that the cabin can be intelligently expanded under low temperature conditions.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an intelligent expandable cabin for oil and gas extraction, comprising a fixed cabin body and two expandable cabin bodies, the two expandable cabin bodies are respectively movably connected on both sides of the fixed cabin body, the inner side of the expandable cabin body is communicated with the fixed cabin body, a sealing wall is extended circumferentially on the outer side surface of the expandable cabin body, a sealing strip is arranged on the inner side of the sealing wall, a fixed cabin floor is paved on the bottom surface of the fixed cabin body, an expandable cabin floor is fixedly connected to the inner side of the bottom surface of the expandable cabin body, a folding floor is hinged between the expandable cabin floor and the fixed cabin floor, low-temperature-resistant electrical components are installed on the inner wall of the outer side surface of the expandable cabin body and above the expandable cabin floor, and the surfaces of the fixed cabin floor, the folding floor and the expandable cabin floor are all covered with electric heating plates.

[0009] The working principle and advantages of this shelter are: when the smart oil and gas field is operated in a plateau and low-temperature area, this expansion shelter installs electrical components that are not resistant to low temperatures on the inner wall of the outer side of the expansion cabin. The unused expansion cabin is in a retracted state. When the shelter needs to be expanded, first turn on the electric heating plate circuit through the manual switch, and the fixed cabin floor, folding floor and expansion cabin floor are all heated, and the heating surfaces of the folding floor and the expansion cabin floor are facing the installation position of the electrical components. Preheating of electrical components that are not resistant to low temperatures is achieved until the ambient temperature of all electrical components meets the operating temperature of the electrical components. After all electrical components are in a temperature range where they can work normally, the expansion system is started to drive the expansion shelter to unfold.

[0010] After the deployment is completed, the shelter can connect the corresponding equipment at each stage of the smart oil and gas field through the Internet of Things, and conduct intelligent command, intelligent monitoring, intelligent safety protection, and intelligent inspection of each equipment. The smart expansion shelter can be used in various links, so that the expansion shelter can be used in turn in multiple operation links, reducing the hardware cost of each link of oil and gas extraction, storage and transportation.

[0011] In addition, when the expansion module is in the folded state, a sealing wall extends circumferentially around the outer side of the expansion module. A sealing strip is provided inside the sealing wall. The expansion module and the fixed module are completely sealed, which also avoids heat loss during the preheating process of electrical components that are not resistant to low temperatures, resulting in preheating failure.

[0012] Furthermore, the electric heating plate structure includes a floor skeleton. Two layers of moisture-proof boards are arranged on the floor skeleton. Graphene heating wires are arranged between the two layers of moisture-proof boards. A surface board for people to walk on covers the upper moisture-proof board.

[0013] The heating rate of the graphene heating wire is six times faster than that of traditional floor heating. It can reach a comfortable temperature in a short time. The graphene heating wire can achieve uniform heating of the entire heating surface, avoiding the problem of uneven heating and cooling of traditional heating materials.

[0014] Furthermore, a heat reflection layer is laid on the inner wall of the bottom of the expansion module. When the expansion module is in the folded state, the heat radiated to the bottom surface of the expansion module can be reflected and utilized.

[0015] Furthermore, a module beam frame is provided at the bottom of the fixed module. A folding space is left between the fixed module and the module beam frame. An expansion mechanism for driving the expansion and folding of the two side expansion modules is installed on the module beam frame. The expansion mechanism includes a travel mechanism for driving the movement of the expansion module. The travel mechanism includes a chute fixedly installed on the module beam frame. A power gear is installed in the chute. A rack fixed to the bottom of the expansion module meshes with the power gear.

[0016] This mobile cabin uses the meshing of a rack and a power gear to determine the travel. Since the tooth pitch of the rack is a fixed value, through the meshing of the gear and the rack, by judging the rotation amount of the gear, the movement amount of the expansion module can be obtained. In this way, sensors do not need to be used as position feedback components, and the expansion travel of the expansion mobile cabin can be accurately judged, reducing the use of sensing components and avoiding failure at low temperatures.

[0017] Furthermore, the expansion mechanism further includes a transmission mechanism for providing power to the travel mechanism. The transmission mechanism includes a servo motor, a reducer, and a transmission shaft. The output end of the servo motor is sequentially connected to the reducer and the transmission shaft. The transmission shaft is coaxially connected to the power gear. An absolute encoder is coaxially installed on the servo motor. The absolute encoder is communicatively connected to a controller. The number of code disks of the absolute encoder is greater than or equal to 3, and the number of tracks of a single code disk is greater than or equal to 2 to the 24th power. The absolute encoder obtains the rotation amount of the servo motor. The controller converts the rotation amount of the servo motor to obtain the movement amount of the expansion module and controls the rotation amount of the servo motor to determine the movement position of the expansion module.

[0018] This application uses a servo motor as the power source and is equipped with a high-precision absolute encoder. The absolute encoder can convert the rotation angle of the motor into an electrical signal and feedback it to the controller. The servo motor has extremely small error range based on the precise position information feedback by the encoder, and no longer uses temperature-sensitive sensors, avoiding the failure of sensors in low-temperature states. Moreover, the combined use of multiple coding disks and multiple tracks realizes more subtle and precise control of the floor movement.

[0019] Furthermore, a rectangular conference table is fixedly installed at the symmetry axis of the fixed cabin floor. The conference table includes a fixed tabletop fixed at the symmetry axis of the fixed cabin floor, and two movable tabletops are respectively hinged on both sides of the fixed tabletop. A lifting rod is hingedly installed on the bottom surface of the movable tabletop.

[0020] Using the conference table in the folded state can allow the expansion cabin to have more space for inward folding, enabling the low-temperature-intolerant electrical components on the expansion cabin to be closer to the electric heating plate and reducing the preheating time.

[0021] Furthermore, a photovoltaic panel is laid on the top of the fixed cabin. A top heating plate with the same power supply circuit as the electric heating plate is provided below the photovoltaic panel, and the photovoltaic panel is slightly inclined.

[0022] In a low-temperature environment, there are often ice floes or snow on the top of the shelter. By having the same power supply circuit for the top heating plate and the electric heating plate, heat is generated by the top heating plate before the photovoltaic panel comes into play, melting the snow or ice floes on the photovoltaic panel, enabling the photovoltaic panel to be used in a low-temperature environment with sunlight.

[0023] Furthermore, a lifting mechanism is provided between the folding floor and the inner side of the expansion cabin. The lifting mechanism includes a first lifting edge fixed below the folding floor and a second lifting edge fixed on the inner wall of the bottom of the expansion cabin. The top of the first lifting edge faces downward, and the top of the second lifting edge faces upward. In the fully expanded state of the expansion cabin, the two inclined surfaces of the first lifting edge and the second lifting edge are in contact.

[0024] After the expansion cabin is fully expanded, the folding floor becomes a flat coplanar state. To avoid the problem that the folding point of the folding floor appears as a dead point when the expansion cabin starts to fold, resulting in the folding floor being unable to be folded. When folding is required, in the fully expanded state of the expansion cabin, the two inclined surfaces of the first lifting edge and the second lifting edge are in contact. When the expansion shelter starts to fold, the lifting mechanism gives an upward thrust to one of the folding floors, causing the folding point of the folding floor to bypass the dead point and completing the normal folding of the folding floor.

[0025] Furthermore, a C-shaped telescopic groove is hinged to the expansion cabin floor. One end of the folding floor is slidably connected to the C-shaped telescopic groove, and a telescopic margin for the movement of the folding floor is reserved in the C-shaped telescopic groove.

[0026] Through the design of the telescopic groove, the extended cabin is first moved by the distance of the telescopic allowance, and through this distance of the telescopic allowance, it is ensured that the tilting mechanism can successfully bypass the dead point of the folding point of the folding floor, avoiding the problem of unsuccessful folding of the folding floor.

[0027] Furthermore, it also includes a centralized control system arranged in the shelter. The centralized control system includes an industrial computer and a controller. The PLC controller is communicatively connected to the oil and gas field equipment and sensors through a serial server, and is used for the process control of the oil and gas field equipment and the data acquisition of the oil and gas field. There are multiple industrial computers, and the industrial computers are signal-connected to the PLC controller through a data switch. The industrial computer is also connected to a video display through a video processor.

[0028] When in a low-temperature environment, the industrial computer and the PLC controller are preheated through a heating plate, so that the core electrical equipment of the control system in the shelter can work normally. The serial server filters the data transmission between the external network and the internal network. The video display is used to display the working interface of the industrial computer currently being concerned, and can be switched to the working interface of any industrial computer according to the signal channel switching, and can comprehensively display all parts of the current operation well.

[0029] The centralized control system controls the internal system of the shelter on the one hand, and on the other hand, is connected to the peripheral equipment of each link of the oil and gas field through signal lines to control the peripheral equipment. Specifically, the peripheral equipment involves the exploration equipment, drilling equipment, maintenance equipment, fracturing equipment, oil and gas production equipment, gathering and transportation equipment, and storage and transportation equipment of the oil and gas field. According to the operation location of this command shelter, the equipment that needs to be controlled at this operation location is selected to be connected to the centralized control system. The centralized control system calls the control software of the corresponding stage to achieve the control of all peripheral equipment at this operation location. When the operation location changes, the equipment that needs to be centrally controlled at the corresponding operation location is connected to this centralized control system in the same operation mode. In this way, the control of various operation modes of the oil and gas field can be completed through one command shelter.

[0030] Furthermore, it also includes an intelligent power distribution system. The intelligent power distribution system includes a three-phase power taking circuit and a single-phase power taking circuit; the three-phase power taking circuit includes three live wires for taking three-phase power and a neutral wire connected to the neutral line. The three live wires respectively form three independent power consumption circuits with the neutral wire, and a first contactor for controlling the conduction of the three live wires is connected to the three live wires. The single-phase power taking circuit includes a single-phase live wire and the common neutral wire of the three-phase power taking circuit. The single-phase live wire is branched into three parallel single-phase live wires, and the three single-phase live wires are first connected to a second contactor and then respectively connected to the incoming line sides of the three power consumption circuits. An uninterruptible power supply is connected in parallel on one of the three power consumption circuits.

[0031] When three-phase electricity is used for power supply, it is connected to the three-phase electricity through the three-phase power circuit, and the normally open contact of the first contactor is closed. The three live wires of the three-phase electricity are used as the power circuits of the intelligent expansion cabin for oil and gas extraction, and the electrical equipment in the intelligent expansion cabin for oil and gas extraction is connected to any of the power circuits. When single-phase electricity is used for power supply, it is connected to the unidirectional electricity through the single-phase power circuit. The single live wire in the single-phase power circuit is divided into three paths, and the three paths are respectively connected to the three power circuits. When the second contactor is closed, the three power circuits are powered at the same time to supply electricity to the equipment in the intelligent expansion cabin for oil and gas extraction. One of the three power circuits is connected in parallel with an uninterruptible power supply. When there is a three-phase power circuit or a single-phase power circuit for power supply, the uninterruptible power supply is charged, and the control signals of the internal equipment of the cabin and the peripheral equipment of the work site are connected to this power circuit.

[0032] The power circuits of the intelligent expansion shelter for oil and gas production include: cabinet power circuit, server power circuit, transmission mechanism power circuit, lodging mechanism / lifting rod power circuit, lighting power circuit, drone airport power circuit, public display area power circuit, conference multimedia power circuit, air conditioning power circuit, graphene heating floor power circuit, socket circuit connected to the mains, socket circuit connected to the UPS power supply, communication system power circuit, ventilation system power circuit, and intelligent control system power circuit. According to actual needs, the corresponding power circuit is connected to the power circuit so that the power equipment on the circuit can be powered.

[0033] Furthermore, it also includes an intelligent inspection system, which includes a drone airport located in a fixed cabin, a warehouse for accommodating multiple drones is provided on the top of the fixed cabin, the drone airport is equipped with a lifting platform, and drones are sent into the drone airport through the lifting platform. The lifting platform is equipped with a positioning rod and a wireless charger. The drone has a lightweight photovoltaic film on its surface, and the drone is equipped with a multi-spectral camera and a lidar. The drone software is equipped with a RANSAC-SLAM algorithm to generate a centimeter-level precision map. The multi-spectral camera and the lidar cooperate with the centimeter-level precision map to form a drone cruising environment for accurately planning the drone cruising path.

[0036] Embodiment 1 Basically as shown in Figure 1 , Figure 2 , Figure 4 and Figure 10 the intelligent extended cabin for oil and gas extraction includes a fixed cabin body 1 and two extended cabin bodies 2. The two extended cabin bodies 2 are respectively movably connected to both sides of the fixed cabin body 1. The inner side of the extended cabin body 2 is communicated with the fixed cabin body 1. A sealing wall 21 extends circumferentially around the outer side of the extended cabin body 2. A sealing strip 22 is provided inside the sealing wall 21. A fixed cabin floor 3 is laid on the bottom surface of the fixed cabin body 1. An extended cabin floor 31 is fixedly connected to the inner side of the bottom surface of the extended cabin body 2. A folding floor 4 is hinged between the extended cabin floor 31 and the fixed cabin floor 3.

[0037] Above the floor 31 of the expansion module and on the inner wall of the outer side of the expansion module body, there are low-temperature-intolerant electrical components 8 installed. The upper surfaces of the fixed cabin floor 3, the folding floor 4, and the expansion module floor 31 are all covered with electric heating plates. The electric heating plate structure includes a floor skeleton, two moisture-proof plates are arranged on the floor skeleton, graphene heating wires are arranged between the two moisture-proof plates, and a surface plate for people to walk on is covered on the upper moisture-proof plate.

[0038] The heating rate of the graphene heating wire is 6 times faster than that of traditional floor heating, and it can reach a comfortable temperature in a short time. The graphene heating wire can achieve uniform heating of the entire heating surface, avoiding the problem of uneven heating and cooling of traditional heating materials. A heat reflection layer is laid on the inner wall of the bottom of the expansion module body to prevent heat from dissipating from the bottom of the expansion module body.

[0039] In the power supply of the expansion module, a separate power supply circuit is arranged for the electric heating plate, and a manually operated mechanical switch is set on this power supply circuit. The operation position of the mechanical switch is outside the expansion shelter, which is convenient for starting only the power supply circuit for the electric heating plate before starting the power supply of other equipment.

[0040] When the intelligent oil and gas field operation is carried out in high-altitude and low-temperature areas, the low-temperature-intolerant electrical components 8 of this expansion shelter are installed on the inner wall of the outer side of the expansion module body 2. The expansion module body 2 in the unused state is in a contracted state. When the expansion shelter needs to be expanded, the electric heating plate circuit is opened through the manual switch, and the fixed cabin floor 3, the folding floor 4, and the expansion module floor 31 all generate heat. The heating surfaces of the folding floor 4 and the expansion module floor 31 are facing the installation positions of the low-temperature-intolerant electrical components 8, realizing preheating of the low-temperature-intolerant electrical components 8, so that all low-temperature-intolerant electrical components 8 are in the temperature range where they can work normally. At this time, start the expansion system to drive the expansion shelter to unfold.

[0041] As Figure 1 and Figure 3 shown, there is an inner sealing wall at the inner edge of the expansion module body 2, and a sealing strip 22 is provided on the inner sealing wall. When the expansion module body is fully unfolded, the sealing strip 22 on the inner sealing wall is closely attached to the fixed cabin body 1 to prevent heat dissipation after the expansion module body 2 is fully unfolded.

[0042] Embodiment 2 As Figure 1 、 Figure 4 and Figure 9 shown, there is a cabin beam frame 7 at the bottom of the fixed cabin body 1. There is a folding space between the fixed cabin body 1 and the cabin beam frame 7. An expansion mechanism for driving the expansion and folding of the two side expansion module bodies is installed on the cabin beam frame 7. The expansion mechanism includes a stroke mechanism for driving the movement of the expansion module body. The stroke mechanism includes a chute 75 fixedly installed on the cabin beam frame, a power gear 10 installed in the chute 75, and a rack 5 fixed to the bottom of the expansion module body. The rack 5 meshes with the power gear 10.

[0043] The expansion mechanism further includes a transmission mechanism that provides power to the stroke mechanism. The transmission mechanism includes a servo motor 71, a speed reducer 73, and a transmission shaft 74. The output end of the servo motor 71 is sequentially connected to the speed reducer 73 and the transmission shaft 74. The transmission shaft 74 is coaxially connected to the power gear 10. An absolute encoder 72 is coaxially installed on the servo motor 71. The absolute encoder 72 is communicatively connected to a controller. The number of code disks of the absolute encoder 72 is greater than or equal to 3, and the number of tracks of a single code disk is greater than or equal to 2 to the 24th power. The absolute encoder obtains the rotation amount of the servo motor 71. The controller converts the rotation amount of the servo motor 71 to obtain the movement amount of the expansion cabin 2, and controls the rotation amount of the servo motor to determine the movement position of the expansion cabin 2.

[0044] A servo motor is used as the power source and is equipped with a high-precision absolute encoder. The absolute encoder can convert the rotation angle of the motor into an electrical signal and feedback it to the controller. The servo motor has an extremely small error range through the precise position information fed back by the encoder and no longer uses temperature-sensitive sensors, avoiding the failure of sensors in low-temperature states. The combined use of multiple code disks and multiple tracks enables more subtle and precise control of the floor movement. The servo motor is driven by a dedicated driver.

[0045] Since sensors whose accuracy is affected by temperature are not used in the high-altitude low-temperature environment, when selecting a servo motor, a servo motor with stall stop rotation and self-protection function is adopted. In this embodiment, the NSD8381 / NSD8389 stepping motor can be used. The temperature range that this motor can adapt to is -40°C to +85°C. The equipped driver supports sensorless stall detection and can effectively detect the stall situation of the motor. When the expansion cabin is being towed, if the gear and rack are jammed, after the servo motor itself detects the stall of the motor, it stops towing and gives an alarm.

[0046] In this solution, the traditional gearbox is omitted, and the output shaft of the servo motor is directly connected to the speed reducer. Sufficient traction is required to achieve expansion. In this embodiment, the NMRV130 worm gear speed reducer is selected for the speed reducer, and the reduction ratio is 100:1.

[0047] Embodiment 3 As Figure 1 and Figure 5 shown, a lifting mechanism is provided between the folding floor 4 and the inner side of the expansion cabin 2. The lifting mechanism includes a first lifting edge 41 fixed under the folding floor and a second lifting edge 42 fixed on the inner wall of the bottom of the expansion cabin 2. The top of the first lifting edge 41 faces downward, and the top of the second lifting edge 42 faces upward. In the fully unfolded state of the expansion cabin 2, the two inclined surfaces of the first lifting edge 41 and the second lifting edge 42 are in contact with each other.

[0048] After the expansion cabin 2 is fully deployed, the folding floor 4 becomes flat and coplanar. To avoid the problem that when the expansion cabin 2 starts to fold, the folding point of the folding floor appears as a dead point, resulting in the folding floor being unable to be folded. When folding is required, in the fully deployed state of the expansion cabin, the two inclined surfaces of the first warping edge 41 and the second warping edge 42 are in contact with each other. When the expansion cabin 2 starts to fold, the warping mechanism gives one of the folding floors an upward thrust, so that the folding point of the folding floor bypasses the dead point and completes the normal folding of the folding floor.

[0049] As Figure 6 and Figure 7 shown, the expansion cabin floor 31 is hinged with a C-shaped telescopic groove 32. One end of the C-shaped telescopic groove 32 is slidably connected to the folding floor 4 within the C-shaped telescopic groove 32, and a telescopic allowance for the movement of the folding floor 4 is reserved within the C-shaped telescopic groove 32. Through the design of the telescopic groove, first let the expansion cabin 2 move a distance of the telescopic allowance. By this distance of the telescopic allowance, it is ensured that the warping mechanism can successfully make the folding point of the folding floor bypass the dead point and avoid the problem that the folding floor cannot be folded successfully.

[0050] A rectangular conference table 6 is fixedly installed at the axis of symmetry of the fixed cabin floor 3. The conference table 6 includes a fixed tabletop fixed at the axis of symmetry of the fixed cabin floor 3, and two movable tabletops are respectively hinged on both sides of the fixed tabletop. The bottom surface of the movable tabletop is hinged with a lifting rod.

[0051] As Figure 8 shown, both ends of the fixed cabin 1 are independent functional cabins 12 and warm air cabins 13. An elevator car is provided in the functional cabin 12. There is an opening at the top of the functional cabin 12 for the elevator car to rise to the top of the functional cabin. A sealing plate is provided at the top of the elevator car for sealing the opening at the top of the functional cabin when the elevator car is stored in the functional cabin.

[0052] The functional cabin and the warm air cabin are part of the fixed cabin. An elevator car is provided in the functional cabin, and the elevator car can be used by the personnel in the cabin to reach the top surface of the functional cabin. If the elevator car lifting function is not used, the elevator car can be used as a storage room. A sealing plate is provided at the top of the elevator car to prevent the heat in the functional cabin from dissipating.

[0053] As Figure 6 shown, a photovoltaic panel is provided on the top of the fixed cabin. The photovoltaic panel is connected to the top of the fixed cabin through an automatic tracking system below. The automatic tracking system includes a rotating shaft for controlling the angle adjustment of the photovoltaic panel, a photosensitive sensor for judging the position of the sun, and a gyroscope angle sensor for judging the adjustment direction of the rotating shaft.

[0054] The photovoltaic panel provides electrical energy for the extended shelter. In sunny conditions, the attitude of the photovoltaic panel is adjusted by an automatic tracking system so that the photovoltaic panel is inclined and directly irradiated by sunlight. During the power generation process of the photovoltaic panel, the snow or ice on the photovoltaic panel can be melted by the sunlight heat and the waste heat generated by its own power generation, enabling the photovoltaic panel to be used in a low-temperature environment with sunlight.

[0055] As Figure 10 shown in the figure, a ladder 17 is externally hung on the warm air cabin 13, enabling the staff to choose the ladder 17 to climb to the top of the shelter when they need to work on the top of the shelter.

[0056] An air conditioner outdoor unit is installed in the warm air cabin 13, and an air outlet 14 extending to the functional cabin is installed on the top of the fixed cabin body 1. When the extended shelter is preheated and successfully extended, the air conditioner outdoor unit 16 is turned on, and the warm air in the air conditioner is introduced into the entire extended shelter and the functional cabin through the air outlet to ensure that the temperature in the entire shelter remains in a comfortable temperature environment.

[0057] Embodiment 4 As Figure 8 shown in the figure, an unmanned airport 15 capable of lifting is also provided on the top of the fixed cabin body. The unmanned airport 15 is shielded by a shielding cover above. Usually, the unmanned aerial vehicle is placed in the unmanned airport 15. When the unmanned aerial vehicle needs to operate, the shielding cover on the top of the unmanned airport 15 is opened to release the unmanned aerial vehicle. The unmanned airport is equipped with a lifting platform. The unmanned aerial vehicle is sent into the unmanned airport through the lifting platform. The lifting platform is equipped with a positioning rod and a wireless charger. The surface of the unmanned aerial vehicle is a lightweight photovoltaic film. The unmanned aerial vehicle is equipped with a multi-spectral camera and a lidar. The unmanned aerial vehicle software is equipped with an RANSAC-SLAM algorithm to generate a centimeter-level precision map. The multi-spectral camera and the lidar cooperate with the centimeter-level precision map to form the cruising environment of the unmanned aerial vehicle for accurately planning the cruising path of the unmanned aerial vehicle. The unmanned aerial vehicle is equipped with a lightweight photovoltaic film, and the endurance is increased to 120 minutes.

[0058] Embodiment 5: As Figure 11 shown in the figure, the intelligent power distribution system of the intelligent extended shelter for oil and gas exploitation includes a three-phase power taking circuit and a single-phase power taking circuit; the three-phase power taking circuit includes three live wires L1 / L2 / L3 for taking three-phase power and a neutral wire N connected to the neutral line.

The centralized control system calls the control software for the corresponding stage to achieve the control of all peripheral equipment at this operating location. When the operating location changes, use the same operation method to connect the equipment that needs to be centrally controlled at the corresponding operating location to this centralized control system. In this way, the control of various operation modes in the oil and gas field can be completed through one command mobile cabin.
