Description

Technical Field

[0001] This application belongs to the field of high-voltage chamber deployment technology, and specifically relates to a rapid deployment method and system for a mobile high-voltage chamber. Background Technology

[0002] In power emergency response, power construction in remote areas, and temporary power supply scenarios, mobile high-voltage rooms serve as key power hub equipment, and their deployment efficiency and reliability directly determine the timeliness and stability of power supply.

[0003] Traditional methods for deploying mobile high-voltage rooms suffer from several shortcomings, leading to overall inefficiency and potential quality issues. First, the site survey phase relies heavily on manual on-site measurements. This method is not only time-consuming and labor-intensive, but also struggles to achieve comprehensive and accurate surveys in complex terrain or large areas, potentially resulting in unsuitable deployment sites, causing difficulties in subsequent construction, and even rework. Second, during the high-voltage room placement and fixing phase, simple lifting equipment is typically used for hoisting, lacking high-precision positioning guidance measures. Alignment relies heavily on the experience of operators, which can easily lead to positional deviations, affecting installation accuracy and stability. Third, in the electrical equipment connection phase, manual plugging and unplugging of cable connectors or on-site cable wiring are commonly used.

[0004] In existing technologies, this method is labor-intensive, and it is difficult to guarantee the accuracy of the connection. Misalignment and poor connection can easily lead to increased contact resistance, localized overheating, or even arcing failures, seriously affecting the reliability and safety of electrical connections. In addition, traditional deployment methods lack rapid and effective temporary protection measures against severe weather, which may affect the normal operation of equipment or accelerate equipment aging. Summary of the Invention

[0005] The purpose of this application is to provide a method and system for the rapid deployment of mobile high-voltage rooms. This addresses the problems of traditional mobile high-voltage room deployments, such as time-consuming and labor-intensive surveying, poor site adaptability, low hoisting and positioning accuracy, low electrical connection efficiency and insufficient reliability, and lack of protection against severe weather, resulting in low overall deployment efficiency and significant quality risks.

[0006] To achieve the above objectives, this application adopts the following technical solution: Firstly, a method for rapid deployment of a mobile high-voltage chamber is provided, including the following steps: S1: Form a swarm of reconnaissance drones to conduct preliminary exploration of the required deployment locations on the ground; S2: Assemble a ground exploration team to verify the ground data collected by the UAV swarm and determine the deployment area of ​​the high-voltage chamber; S3: The mobile high-voltage chamber is pre-assembled in the factory and then transported and hoisted for deployment; S4: Automated connection of the electrical equipment in the high-voltage room; S5: Complete the deployment of the high-voltage chamber.

[0007] In one possible implementation, step S1, the reconnaissance step of the drone swarm includes: S11: Set the flight altitude and speed of the drone swarm, with an overlap rate of ≥30% between adjacent flight paths, and conduct aerial surveys of the deployment site using a grid coverage method; S12: Each drone is equipped with a lidar, a high-definition camera, and a positioning module to collect ground deployment location information; S13: The drone transmits the collected data to the back-end planning system in real time. The system automatically generates a 3D model of the site and marks areas unsuitable for deployment. The unsuitable deployment areas include areas with a ground slope greater than 15°, as well as areas with dense pipelines on or above the ground.

[0008] In one possible implementation, step S2, the specific steps for formulating the improvement measures, include: S21: Select the ground treatment method according to the ground hardness of the suitable deployment area; S22: If the ground is a cement floor or an asphalt floor, the load-bearing area is directly spliced ​​out using modular metal load-bearing plates. The area of ​​the load-bearing area is larger than the area of ​​the bottom of the high-pressure room, and the metal load-bearing plates are fixed to the ground by anchor bolts or expansion bolts. S23: If the ground is soil or gravel, add 2%-4% quick-setting agent to the cement by the total mass of cement, spread the cement evenly on the ground, and after it solidifies, use the modular metal load-bearing plates to splice out the load-bearing area. S24: A foundation adjustment bolt is reserved on the bearing area for connecting to the high-pressure chamber.

[0009] In one possible implementation, step S3, the pre-installation and deployment steps of the mobile high-voltage chamber, include: S31: The high-voltage switchgear, transformer and automation equipment are pre-integrated and installed in the high-voltage room in the factory workshop, and an I-shaped steel structure base is installed at the bottom of the high-voltage room, the steel structure base extending to the outside of the high-voltage room; S32: Fix multiple annular airbags stacked from bottom to top at the edge of the steel structure base; S33: Affix reflective markings and RFID tags to the side of the high-pressure chamber. The RFID tags store information about the weight, dimensions, and center of gravity of the chamber. S34: After the transport vehicle arrives at the site, the technicians scan the RFID tag through the construction terminal to obtain the center of gravity position of the cabin and the positioning hole parameters. The background system generates hoisting instructions based on this. S35: During the hoisting process, the alignment deviation between the high-pressure chamber positioning hole and the foundation adjustment bolt is detected in real time by the laser positioning sensor, and the position of the crane boom is finely adjusted by the crane control system to make the alignment deviation ≤2mm; after the high-pressure chamber is in place, the fixing nut is tightened to complete the fixation of the chamber.

[0010] In one possible implementation, in step S32, after the high-pressure chamber is deployed, if it rains or snows, the annular airbag is inflated to raise its height and form a wrapping structure around the high-pressure chamber, and a heat dissipation space of 0.2-0.4m is reserved between the inner wall of the annular airbag and the outer wall of the high-pressure chamber.

[0011] In one possible implementation, step S4, the step of automated electrical equipment docking, includes: S41: The transformer, switchgear and cables in the high-voltage room are electrically connected by a prefabricated cable connector combined with an automatic docking mechanism. Among them, the incoming interfaces of transformers and switchgear are sub-interfaces, and the cable ends are female connectors; S42: The automatic docking mechanism includes an electric push rod installed in the high-pressure chamber, and the telescopic end of the electric push rod is connected to the female connector; S43: During factory pre-assembly, adjust the position of the electric push rod according to the position of the sub-interface so that the female connector is aligned with and fixed to the sub-interface; S44: During on-site commissioning, start the electric push rod to push the female connector into the corresponding sub-interface to complete the connection between the cable and the electrical equipment.

[0012] In one possible implementation, a pre-installation test step is included after step S43 and before step S44: The electric push rod is repeatedly activated to drive the female connector to perform insertion and removal tests within the sub-interface, and the number of insertions and removals and the continuity rate are recorded.

[0013] In one possible implementation, after step S44, a verification step is further included: Start all electrical equipment in the high-voltage room and verify their operating status; If it is running well, then put it into use; If a fault is found, repair and maintenance should be carried out until it is running normally.

[0014] In one possible implementation, in step S34, the backend system aligns the basic positioning marker with the cabin positioning hole using augmented reality technology to generate the hoisting guide.

[0015] In a second aspect, a mobile high-voltage chamber system is provided, which is deployed and operated using the rapid deployment method for mobile high-voltage chambers as described in the first aspect.

[0016] Compared with the prior art, this application has the following beneficial effects: This application provides a rapid deployment method for mobile high-voltage rooms. This method solves the problems of incomplete coverage and low efficiency of traditional manual surveys by using a dual survey mode of preliminary exploration by UAVs and precise verification by ground personnel, ensuring accurate selection of deployment areas. The combination of factory pre-assembly and professional transportation and hoisting reduces on-site construction steps and avoids interference from the on-site environment on equipment installation. Automated docking of electrical equipment reduces human operation errors. The entire process is interconnected, significantly improving the deployment efficiency of mobile high-voltage rooms while ensuring deployment quality. It can quickly meet the needs of power emergency protection, power construction in remote areas, and temporary power supply scenarios, providing strong support for the timeliness and reliability of power supply.

[0017] In one possible implementation, by specifying the drone flight parameters, the comprehensiveness of aerial surveys and the integrity of data collection are ensured, avoiding blind spots in the survey. The combined use of lidar, high-definition cameras, and dual-mode positioning modules enables the accurate collection of ground elevation, surface features, and geographic location information, providing high-quality data support for subsequent site analysis. The back-end planning system automatically generates 3D models and marks unsuitable deployment areas, significantly reducing manual data processing time, improving the efficiency and accuracy of site analysis, laying the foundation for quickly selecting suitable deployment areas, further optimizing the survey process, and accelerating the overall deployment process.

[0018] In one possible implementation, the treatment method is selected based on the difference in ground hardness. For cement / asphalt ground, metal load-bearing plates are used directly, while for soil / gravel ground, a combination of quick-setting cement and metal load-bearing plates is used. This ensures the load-bearing capacity and stability of the load-bearing area, avoids resource waste, and improves the flexibility and adaptability of site treatment. The difference between the splicing area of ​​the metal load-bearing plates and the size of the high-voltage chamber, as well as the fixing method, are clearly defined to ensure that the load-bearing area can stably support the high-voltage chamber and prevent displacement or settlement after the high-voltage chamber is deployed. Pre-installed foundation adjustment bolts facilitate precise docking of the high-voltage chamber, reduce adjustment time during docking, and ensure the stability of the connection between the high-voltage chamber and the load-bearing area, improving the reliability of the site treatment process and providing a solid foundation for the smooth deployment of the high-voltage chamber.

[0019] In one possible implementation, equipment integration, installation, and dustproofing are completed in the factory, avoiding environmental interference during on-site equipment installation and ensuring installation accuracy and cleanliness. The I-beam steel structure base extends to the perimeter of the high-voltage room, enhancing its overall stability. Reflective markings improve the room's visibility in low-light conditions, while RFID tags store cabin information, providing precise data support for on-site hoisting. Hoisting instructions generated by the back-end system reduce the difficulty of hoisting operations. Laser positioning sensors detect alignment deviations in real time and fine-tune them through the control system, ensuring hoisting positioning accuracy. Manually tightening the fixing nuts further ensures the cabin's stability. The entire pre-installation and hoisting deployment process is standardized and highly accurate, effectively improving the high-voltage room's positioning efficiency and stability.

[0020] In one possible implementation, the annular airbag is made of high-strength PVC mesh fabric, which has good tear resistance and high and low temperature resistance, ensuring reliable protection under severe weather conditions. The precise timing, sequence, pressure, and spacing of the inflation space ensure that the airbag effectively encloses the high-voltage chamber, blocking rain and snow, while also preventing overheating of the high-voltage chamber equipment due to insufficient heat dissipation space. Temperature sensors monitor the temperature of the heat dissipation space in real time, ensuring normal equipment operation. This fills the gap in severe weather protection in traditional deployment methods, effectively protecting the high-voltage chamber equipment, extending its service life, and ensuring the stability of power supply under extreme weather conditions.

[0021] In one possible implementation, repeated plugging and unplugging tests can detect problems such as abnormal operation of the electric actuator, poor fit between the female connector and the female interface, or excessive conduction resistance in advance, avoiding bringing potential faults into the on-site commissioning process and reducing on-site troubleshooting and maintenance time. Recording the number of plugging and unplugging operations and the continuity rate provides a quantitative evaluation basis for connector performance, ensuring that all connectors entering the field have good reliability and stability, further reducing the risk of electrical connection failures on-site, ensuring the safety and stability of subsequent high-voltage room equipment operation, and providing additional assurance for the overall deployment quality.

[0022] A mobile high-voltage chamber system enables efficient operation throughout the entire process, from surveying, site preparation, pre-installation and transportation to electrical connection and operational verification. The system's components and deployment methods are highly compatible, fully leveraging the advantages of the methods and solving many pain points of traditional deployment. The system can quickly respond to the needs of power emergency protection, power construction in remote areas, and temporary power supply scenarios, ensuring the timeliness and stability of power supply. At the same time, it has good reliability and adaptability, and can be efficiently deployed in different terrains and environments, providing a complete and reliable solution for various temporary power demand scenarios.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] like Figure 1 As shown, this application discloses a method for rapid deployment of a mobile high-voltage chamber, which may include the following steps: In a post-disaster power emergency repair scenario, a mobile high-voltage room needs to be deployed quickly.

[0031] S1: Form a fleet of reconnaissance drones to conduct preliminary exploration of the required deployment locations on the ground.

[0032] Specifically, the first step is to form a reconnaissance drone fleet consisting of three industrial-grade drones, each with a flight time of ≥90 minutes and equipped with a dual-battery redundant power supply system, to conduct preliminary exploration of the target deployment area.

[0033] S2: Assemble a ground exploration team to verify the ground data collected by the drone swarm and develop comprehensive measures for unsuitable deployment areas and areas with undulating slopes to form high-voltage chamber deployment areas.

[0034] Specifically, a five-person ground exploration team was then formed, carrying equipment such as slope meters and hardness testers. They checked the slope, ground hardness, and other parameters of suitable deployment locations one by one, comparing them with the ground data collected by drones. For an area with a large slope undulation, they used a combination of cement paving and metal load-bearing plates to deal with it, and finally determined a 20m×15m high-voltage room deployment area.

[0035] S3: After the high-voltage room deployment area is completed, the mobile high-voltage room is pre-assembled in the factory and then transported and hoisted for deployment.

[0036] Optionally, after the deployment area is processed, the mobile high-voltage room will have its high-voltage switchgear, transformers and other equipment pre-installed in the factory. Then, a heavy-duty truck with a hydraulic suspension system will be used to transport it to the project site, where it will be hoisted using a crane and laser positioning.

[0037] S4: Automated connection of the electrical equipment in the high-voltage room.

[0038] Next, the automatic docking mechanism in the high-voltage room is activated to achieve automated docking of the transformer, switchgear and cables.

[0039] S5: Complete the deployment of the high-voltage chamber.

[0040] Finally, the electrical equipment can be connected through an automatic docking mechanism, and the entire high-voltage room deployment can be completed in just 8 hours.

[0041] In this embodiment, the method solves the problems of incomplete coverage and low efficiency of traditional manual surveys by adopting a dual survey mode of "preliminary UAV exploration + precise verification by ground personnel," ensuring accurate selection of deployment areas. The combination of factory pre-installation and professional transportation and hoisting reduces on-site construction steps and avoids interference from the on-site environment on equipment installation. Automated docking of electrical equipment reduces human operation errors. The entire process is interconnected, significantly improving the deployment efficiency of mobile high-voltage rooms while ensuring deployment quality. It can quickly meet the needs of power emergency protection, power construction in remote areas, and temporary power supply scenarios, providing strong support for the timeliness and reliability of power supply.

[0042] In one possible embodiment, step S1, the reconnaissance step of the drone swarm includes: S11: Set the flight altitude of the drone swarm to 40-70m, the flight speed to 3-8m / s, and the overlap rate of adjacent flight paths to ≥30%. Conduct aerial surveys of the deployment site using a grid coverage method.

[0043] Optionally, the flight altitude of the three drones is set to 50m, the flight speed to 5m / s, and the overlap rate of adjacent flight paths is set to 35%. The area surrounding the repair zone is then covered using a grid-based method. Aerial surveys were conducted on the area.

[0044] S12: Each drone is equipped with a lidar, a high-definition camera, and a positioning module to collect ground deployment location information.

[0045] Optionally, each drone is equipped with a lidar with a ranging accuracy of ≤5cm, a 4K resolution anti-backlight high-definition camera, and a GPS and Beidou dual-mode positioning module to collect ground elevation, surface pipeline distribution, and geographical location information in real time during flight.

[0046] S13: The drone transmits the collected data to the back-end planning system in real time. The system automatically generates a 3D model of the site and marks areas unsuitable for deployment.

[0047] The unsuitable deployment areas include areas with a ground slope greater than 15°, as well as areas with dense pipelines on or above the ground.

[0048] Specifically, the drones transmit the collected data to the back-end planning system in real time. The system uses AI algorithms to denoise the laser point cloud data and generates a 3D model of the site with a resolution of 0.4m. It automatically marks three areas with a ground slope greater than 15° and two areas with dense surface pipelines that are unsuitable for deployment. Within 45 minutes of the completion of the survey, it outputs an analysis report containing the 3D model, a map of unsuitable areas, and a list of three recommended suitable areas, and pushes it to the mobile terminals of the ground exploration personnel.

[0049] In this embodiment, by specifying the UAV flight parameters, the comprehensiveness of aerial surveys and the integrity of data collection are ensured, avoiding blind spots in the survey. The combined use of LiDAR, high-definition cameras, and dual-mode positioning modules enables accurate collection of ground elevation, surface features, and geographical location information, providing high-quality data support for subsequent site analysis. The background planning system automatically generates 3D models and marks unsuitable deployment areas, significantly reducing manual data processing time, improving the efficiency and accuracy of site analysis, laying the foundation for quickly selecting suitable deployment areas, further optimizing the survey process, and accelerating the overall deployment process.

[0050] In one possible embodiment, step S2, the specific steps for formulating improvement measures, include: S21: Select the ground treatment method according to the ground hardness of the suitable deployment area.

[0051] S22: If the ground is a cement or asphalt surface, the load-bearing area is directly constructed by splicing modular metal load-bearing plates. The area of ​​this load-bearing area is 0.3-0.5m larger than the bottom area of ​​the high-pressure room, and the metal load-bearing plate is fixed to the ground by anchor bolts or expansion bolts.

[0052] One of the areas was a cement floor, where modular metal load-bearing plates were directly selected. Based on the size of the high-pressure room, a load-bearing area of ​​18.4m × 12.4m was spliced ​​together, and anchor bolts were used to fix the metal load-bearing plates to the cement floor.

[0053] S23: If the ground is soil or gravel, add 2%-4% of the total cement mass as an accelerator to the cement, spread the cement evenly on the ground, and after it solidifies, use the modular metal load-bearing plates to splice out the load-bearing area.

[0054] Another area is a sand and gravel surface. First, add 3% quick-setting agent to the cement to make up the total mass of the cement. Spread the cement evenly on the sand and gravel surface. After the cement has solidified, use modular metal load-bearing plates to splice out a 18.3m×12.3m load-bearing area.

[0055] S24: Foundation adjustment bolts are reserved in this bearing area for connection to the high-pressure chamber.

[0056] Optionally, foundation adjustment bolts are reserved at the four corners and edges of the two load-bearing areas, for a total of 24 bolts, for subsequent connection to the high-pressure chamber.

[0057] In this embodiment, the treatment method is selected based on the difference in ground hardness. For cement / asphalt ground, metal load-bearing plates are used directly, while for soil / gravel ground, a combination of quick-setting cement and metal load-bearing plates is used. This ensures the load-bearing capacity and stability of the load-bearing area, avoids resource waste, and improves the flexibility and adaptability of site treatment. The difference between the splicing area of ​​the metal load-bearing plates and the size of the high-voltage chamber, as well as the fixing method, are clearly defined to ensure that the load-bearing area can stably support the high-voltage chamber and prevent displacement or settlement after the high-voltage chamber is deployed. The reserved foundation adjustment bolts facilitate the precise docking of the high-voltage chamber in the future, reduce the adjustment time during the docking process, and ensure the stability of the connection between the high-voltage chamber and the load-bearing area. This improves the reliability of the site treatment process and provides a solid foundation for the smooth deployment of the high-voltage chamber.

[0058] In one possible embodiment, step S3, the pre-installation and deployment steps of the mobile high-pressure chamber, include: S31: The high-voltage switchgear, transformer and automation equipment are pre-installed in the high-voltage room in the factory workshop, and an I-shaped steel structure base is installed at the bottom of the high-voltage room, which extends to the outside of the high-voltage room.

[0059] Inside the factory workshop, the integration and installation of 3 high-voltage switchgear, 2 transformers and 4 sets of automation equipment in the high-voltage room were completed first. Dust plugs were used to prevent dust from entering the wiring holes of the equipment. Then, an I-shaped steel structure base was installed at the bottom of the high-voltage room, with the base extending 0.6m to the outside of the high-voltage room.

[0060] S32: Fix multiple annular airbags stacked from bottom to top at the edge of the steel structure base.

[0061] Five high-strength PVC mesh fabric ring-shaped airbags are fixed on each side of the steel structure base. The diameter of each airbag is 15cm shorter than the side length of the corresponding side of the high-pressure chamber, the height is 25cm, and the thickness is 2.2mm. The ring-shaped airbags are stacked from bottom to top, with a total of 3 layers.

[0062] S33: Affix reflective markings and RFID tags to the side of the high-pressure chamber. The RFID tags store information about the weight, dimensions, and center of gravity of the chamber.

[0063] Four reflective strips were affixed to the front and rear sides of the high-pressure chamber, along with RFID tags storing information on the chamber's weight, dimensions, and center of gravity.

[0064] S34: After the transport vehicle arrives at the site, technicians scan the RFID tag through the construction terminal to obtain the center of gravity position of the cabin and the positioning hole parameters. The background system generates hoisting instructions based on this.

[0065] After the transport vehicle arrives at the site, technicians scan the RFID tag through the construction terminal to obtain the center of gravity of the cabin and the parameters of the positioning hole, and the background system generates detailed hoisting instructions.

[0066] S35: During the hoisting process, the alignment deviation between the high-pressure chamber positioning hole and the foundation adjustment bolt is detected in real time by the laser positioning sensor, and the position of the boom is finely adjusted by the crane control system to make the alignment deviation ≤2mm; after the high-pressure chamber is in place, the fixing nut is tightened to complete the cabin fixation.

[0067] During hoisting, the crane's laser positioning sensor detects the alignment deviation between the high-pressure chamber positioning hole and the foundation adjustment bolt in real time. When a deviation of 3mm is detected, the crane control system fine-tunes the boom position to ultimately control the alignment deviation to 1.5mm. After the high-pressure chamber is lowered to the foundation, the 24 fixing nuts at the positioning hole are manually tightened to complete the chamber fixation.

[0068] In this embodiment, equipment integration, installation, and dustproofing are completed in the factory, avoiding environmental interference during on-site equipment installation and ensuring installation accuracy and cleanliness. The I-shaped steel structure base extends to the perimeter of the high-voltage room, enhancing its overall stability. Reflective markings improve the high-voltage room's visibility in low-light environments, and the RFID tags storing cabin information provide accurate data support for on-site hoisting. The hoisting instructions generated by the back-end system reduce the difficulty of hoisting operations. Laser positioning sensors detect alignment deviations in real time and fine-tune them through the control system, ensuring hoisting positioning accuracy. Manually tightening the fixing nuts further ensures the stability of the cabin. The entire pre-installation and hoisting deployment process is standardized and highly accurate, effectively improving the efficiency and stability of the high-voltage room's placement.

[0069] In one possible embodiment, in step S32, after the high-pressure chamber is deployed, if it rains or snows, the annular airbag is inflated to increase its height and form a wrapping structure around the high-pressure chamber, and a heat dissipation space of 0.2-0.4m is reserved between the inner wall of the annular airbag and the outer wall of the high-pressure chamber.

[0070] Once the high-pressure chamber was deployed, a weather warning indicated moderate rain was expected in the next 24 hours.

[0071] One hour before the rainfall, technicians started the inflation operation of the annular airbags. Using an electric air pump, they inflated the annular airbags around the high-pressure chamber in the order of lower layer to upper layer. The inflation pressure of each airbag was controlled at 0.1 MPa. After the pressure reached the set value, the valve was closed, and the inflation time and pressure value were recorded at the same time.

[0072] After inflation, the annular airbag rises to a height of 75cm, forming a complete enveloping structure for the high-pressure chamber. Measurements show that the distance between the inner wall of the annular airbag and the outer wall of the high-pressure chamber is 0.3m, creating an effective heat dissipation space.

[0073] Two temperature sensors were installed in the heat dissipation space to monitor temperature changes in real time. The monitoring data showed that the temperature in the heat dissipation space was always ≤3℃ different from the ambient temperature, and no rainwater seeped into the high-pressure chamber during rainfall, indicating that the equipment was operating normally.

[0074] In this embodiment, the annular airbag is made of high-strength PVC mesh fabric, which has good tear resistance and high and low temperature resistance, ensuring reliable protection under severe weather conditions. The precise timing, sequence, pressure, and spacing of the inflation space ensure that the airbag effectively encloses the high-voltage chamber, blocking rain and snow, while also preventing overheating of the high-voltage chamber equipment due to insufficient heat dissipation space. A temperature sensor monitors the temperature of the heat dissipation space in real time, ensuring normal equipment operation and filling the gap in severe weather protection in traditional deployment methods. This effectively protects the high-voltage chamber equipment, extends its service life, and ensures the stability of power supply under extreme weather conditions.

[0075] In one possible embodiment, step S4, the step of automated electrical equipment docking, includes: S41: The transformers, switchgear and cables in the high-voltage room are electrically connected by prefabricated cable connectors combined with an automatic docking mechanism.

[0076] The incoming interfaces of the transformer and switchgear are sub-interfaces, and the cable ends are female connectors.

[0077] Optionally, the two transformers and four switchgear cabinets in the high-voltage room are electrically connected to the cables using prefabricated cable connectors and an automatic docking mechanism. The incoming interfaces of the transformers and switchgear cabinets are set as sub-interfaces, and the cable ends are set as female connectors.

[0078] S42: The automatic docking mechanism includes an electric actuator installed in the high-pressure chamber, the telescopic end of which is connected to the female connector.

[0079] Optionally, the automatic docking mechanism includes eight electric actuators installed on the inner wall of the high-pressure chamber. Each electric actuator is fixed by a stainless steel bracket, and a shock-absorbing pad is installed between the bracket and the actuator. The telescopic end of the electric actuator is connected to the cable female connector through a special clamp.

[0080] S43: During factory pre-assembly, adjust the position of the electric push rod according to the position of the sub-interface to align and fix the female connector with the sub-interface.

[0081] Optionally, during factory pre-installation, a laser positioning device is used to calibrate the installation angle of the electric push rod to ensure that the extension and retraction direction of the push rod is completely consistent with the center axis of the sub-interface. The position of the electric push rod is adjusted according to the position of the sub-interface to ensure that the female connector and the sub-interface are precisely aligned and then fixed.

[0082] S44: During on-site commissioning, start the electric push rod to push the female connector into the corresponding sub-interface to complete the connection between the cable and the electrical equipment.

[0083] Optionally, during on-site commissioning, the electric push rod on one side of each electrical device is activated. The push rod slowly inserts the female connector into the corresponding sub-interface. All 8 sets of female and sub-connectors are successfully connected, realizing the conduction between the cable and the electrical equipment. The connection process takes 25 minutes.

[0084] In this embodiment, the automatic docking mechanism consisting of prefabricated cable connectors and electric push rods replaces the traditional manual insertion and removal of cable connectors, significantly reducing labor intensity. The electric push rod, fixed by a bracket and calibrated by laser positioning, ensures the consistency of the push rod's extension direction with the sub-interface. Combined with a dedicated clamp to fix the female connector, it effectively avoids misalignment problems that are prone to occur during manual docking, improving docking accuracy. During on-site commissioning, docking can be completed simply by activating the electric push rod, significantly shortening electrical docking time and reducing the risk of malfunctions such as poor contact caused by human operation errors. This ensures the reliability of electrical connections, further optimizes the deployment process, and improves overall deployment efficiency.

[0085] In one possible embodiment, a pre-installation test step is included after step S43 and before step S44: Repeatedly start the electric push rod to drive the female connector to perform insertion and removal tests within the sub-interface, and record the number of insertions and removals and the continuity rate.

[0086] After the electric actuator and female connector are pre-installed and fixed in the factory (step S43) and before on-site commissioning (step S44), a pre-installation test is conducted.

[0087] Connect the temporary power supply in the high-voltage room to ensure stable power supply to the electric push rods. Repeatedly start the 8 electric push rods to drive the female connector to perform insertion and removal tests in the sub-interface, for a total of 50 insertion and removal cycles.

[0088] During the test, the time of each insertion and removal, whether there is any jamming or abnormal noise, are recorded in real time. At the same time, the continuity resistance value is monitored by a resistance detector and the continuity rate is recorded.

[0089] During testing, it was found that one electric actuator slightly jammed during the 32nd insertion and removal. Inspection revealed a small amount of impurities in the actuator guide rail. After cleaning the impurities and applying lubricant, the jamming disappeared. The final test report showed that the continuity rate was 100% during 50 insertion and removal cycles, with no abnormalities. After confirming that the connector was qualified, the on-site commissioning phase began.

[0090] In this embodiment, repeated insertion and removal tests can detect problems such as abnormal operation of the electric push rod, poor fit between the female connector and the female interface, or excessive conduction resistance in advance, avoiding bringing potential faults into the on-site commissioning process and reducing on-site troubleshooting and maintenance time. Recording the number of insertions and removals and the continuity rate provides a quantitative evaluation basis for the connector performance, ensuring that all connectors entering the field have good reliability and stability, further reducing the risk of electrical connection failures on-site, ensuring the safety and stability of subsequent high-voltage room equipment operation, and providing additional assurance for the overall deployment quality.

[0091] In one possible embodiment, after step S44, a verification step is further included: Start all electrical equipment in the high-voltage room and verify their operating status.

[0092] If it is running well, it can be put into use.

[0093] If a fault is found, repair and maintenance should be carried out until it is running normally.

[0094] Specifically, the two transformers, four switchgear cabinets, and supporting automation equipment in the high-voltage room were started. The operating parameters of each device, such as voltage, current, and temperature, were monitored in real time through the background control system. At the same time, three technicians were arranged to conduct on-site inspections to check for abnormal noises, oil leaks, loose wiring, and other issues.

[0095] Monitoring data shows that the voltage of each device is stable at 380V±5V, the current fluctuation range is ≤2A, and the temperature is within the normal operating temperature range of the device.

[0096] No abnormalities were found during the on-site inspection, and the electrical equipment was determined to be in good operating condition. The mobile high-voltage room was then put into use.

[0097] In another project, during operation and verification, it was found that the current of one switch cabinet fluctuated greatly, and the system reported an error message "poor cable contact". Based on the error message, the technicians checked the corresponding female and male connectors and found that the internal contacts of the female connector were oxidized. After polishing the contacts with fine sandpaper and applying conductive paste, the equipment was restarted, and the current fluctuation returned to normal, and the equipment was put into use.

[0098] In this embodiment, the operation verification step comprehensively detects the operating status of electrical equipment through a dual approach of control system monitoring and on-site inspection. This enables timely detection of equipment malfunctions, preventing safety accidents or equipment damage caused by putting faulty equipment into use. When a fault is detected, the cause of the fault is accurately located based on the system error message, reducing troubleshooting time, improving maintenance efficiency, and ensuring that the equipment can quickly return to normal operation and be put into use. This further guarantees the reliable operation of the mobile high-voltage room after deployment and provides the last line of defense for the stability of power supply.

[0099] In one possible embodiment, in step S34, the backend system uses augmented reality technology to align the basic positioning markers with the hull positioning holes to generate the hoisting guide.

[0100] After the transport vehicle arrives at the site, technicians use a construction terminal to scan the RFID tag on the side of the high-voltage chamber to obtain the position of the chamber's center of gravity and the parameters of the positioning hole.

[0101] After receiving the data, the back-end system uses augmented reality technology to virtually align the basic positioning marks of the on-site bearing area with the positioning holes of the cabin on the construction terminal screen, generating a visual hoisting guide. The guide clearly marks the crane lifting point position, the initial angle of the boom, the lifting speed, and the fine-tuning prompts during the descent process.

[0102] Technicians directed the crane operation based on the AR alignment screen and hoisting guidelines. The entire hoisting preparation process took 30 minutes, which is 50% shorter than the traditional hoisting preparation method that relies on experience.

[0103] In this embodiment, augmented reality technology virtually aligns the basic positioning markers with the cabin positioning holes, realizing the visualization of the hoisting guidance. This allows technicians to intuitively obtain hoisting parameters and key operational points, reducing reliance on operator experience and minimizing human judgment errors. The visualized hoisting guidance clarifies key parameters such as the hoisting point location and boom angle, providing precise guidance for crane operation, avoiding repeated adjustments during the hoisting process, shortening hoisting preparation time, improving hoisting positioning efficiency and accuracy, further optimizing the hoisting deployment process, and facilitating the efficient advancement of the overall deployment process.

[0104] In one possible embodiment, a mobile high-pressure chamber system is provided, which is deployed and operated using the aforementioned rapid deployment method for mobile high-pressure chambers.

[0105] Optionally, the mobile high-pressure chamber system may include a swarm of reconnaissance drones, ground exploration equipment, the mobile high-pressure chamber itself, a heavy-duty truck with a hydraulic suspension system, a crane, an automatic docking mechanism, and a back-end planning system.

[0106] Deployment is carried out using a rapid deployment method for mobile high-voltage chambers: First, a fleet of drones surveyed the site, and ground personnel verified the processing area. Then, the high-voltage room equipment was pre-installed in the factory and transported to the site. After that, it was hoisted using AR alignment and laser positioning. Finally, the electrical equipment was automatically connected and its operation was verified. After the entire system was deployed, it met the temporary power demand of the mining area for 12 hours a day. It operated stably and no equipment failures occurred.

[0107] In this embodiment, efficient operation of the entire process from surveying, site preparation, pre-installation and transportation to electrical connection and operational verification is achieved. The various components of the system are highly compatible with the deployment method, giving full play to the advantages of the method and solving many pain points of traditional deployment. The system can quickly respond to the needs of power emergency protection, power construction in remote areas and temporary power use scenarios, ensuring the timeliness and stability of power supply. At the same time, it has good reliability and adaptability, and can be efficiently deployed in different terrains and environments, providing a complete and reliable solution for various temporary power demand scenarios.
