Description

Technical Field

[0001] The present application relates to the technical field of high-voltage combined electrical equipment, and in particular to a container-type maintenance cabin for on-site maintenance of high-voltage combined electrical equipment. Background Art

[0002] Currently, during the installation and maintenance of high-voltage combination electrical systems, a clean environment is a key factor in ensuring the normal operation and stable maintenance of the equipment. High-voltage combination electrical systems are widely used in power transmission and distribution systems, and their core components have high requirements for environmental cleanliness and stability. To prevent dust and impurities from affecting the installation, maintenance, and operation of the equipment, the relevant fields have established strict standards for the cleanliness of the working environment. Typically, a clean environment relies on a fixed clean room, but this approach cannot meet the flexibility requirements of on-site installation. This is especially true for the maintenance of electrical equipment in the field or for specific projects, which requires more flexible and easy-to-move clean maintenance equipment.

[0003] Currently, some existing solutions utilize temporary cleanrooms, combined with fresh air equipment and filtration systems, to provide a relatively clean environment. These cleanrooms are typically constructed with steel frames and tarpaulins, and fresh air equipment is used to maintain air cleanliness within. However, existing cleanrooms are relatively rudimentary, lacking sealing and stability, and cannot fully meet the maintenance requirements of high-voltage combination electrical equipment. Especially during precision operations, cleanliness and temperature control are difficult to meet, and air quality fluctuates significantly, making it difficult to ensure equipment safety and maintenance quality. Furthermore, these temporary cleanrooms are complex to install and dismantle, and structural integrity is difficult to maintain during transportation.

[0004] Existing technologies lack a maintenance device that provides a stable clean environment while also being highly portable and portable. This is particularly true for high-voltage combined electrical equipment maintenance, where existing cleanroom systems struggle to maintain cleanliness and environmental stability, impacting equipment reliability. Therefore, a cleanroom maintenance cabin with high cleanroom controllability, suitable for rapid deployment and reliable use in diverse environments, is urgently needed. Utility Model Content

[0037] See also Figures 1-4 , Figure 1 A schematic diagram of the overall structure of a containerized maintenance cabin for high-voltage combined electrical field maintenance provided in one embodiment of the present application; Figure 2 A schematic structural diagram of an inspection cabin provided in one embodiment of the present application; Figure 3 A schematic diagram of the interior of an inspection cabin provided in one embodiment of the present application; Figure 4 This is a schematic diagram of the air shower room provided in one embodiment of the present application being moved into the maintenance cabin. Figures 1-4 As shown, an embodiment of the present application provides a container-type maintenance cabin for high-voltage combined electrical on-site maintenance, including a maintenance cabin body 100 made of a container, a double-door 200, a fresh air system 300, an air shower room 500, an industrial air conditioner 400 and a transfer vehicle 700.

[0038] The maintenance cabin 100 is a metal square frame structure. The inner panels of the maintenance cabin 100 are metal panels filled with thermal insulation and flame retardant materials. The floor inside the maintenance cabin 100 is an epoxy self-leveling floor. A skylight 110 is provided on the front outer wall of the maintenance cabin 100.

[0039] The inspection compartment 100 has two double-leaf doors 200, each with a soft curtain 600. These doors provide ample space for the entry and exit of large equipment, particularly large high-voltage electrical components. The soft curtains 600 enhance the seal, effectively preventing dust and contaminants from entering the compartment while the doors are open. Furthermore, the curtains 600 can be flexibly opened or closed for ease of use.

[0040] The fresh air system 300 is used to purify the air within the maintenance cabin 100. The main unit of the fresh air system 300 is mounted on the exterior wall of the maintenance cabin 100. This system 300 not only purifies the air within the maintenance cabin 100 but also filters external air, ensuring that the air entering the cabin meets the strict cleanliness requirements of on-site maintenance. Furthermore, the main unit of the fresh air system 300 is mounted outside the cabin, reducing the impact of noise generated by the operation of the equipment on operators within the cabin.

[0041] The air shower 500 is used to remove dust from personnel entering the maintenance cabin 100 by blowing air. A personnel entrance 120 is provided on the front outer wall of the maintenance cabin 100. The personnel entrance 120 is located on one of the left and right sides of the skylight 110, allowing personnel in the air shower 500 to enter the maintenance cabin 100 after dust removal. The air shower 500 is located outside the personnel entrance 120. The personnel entrance 120 also serves as an inlet and outlet passage for the air shower 500 to move into the maintenance cabin 100. During use, the air shower 500 removes dust from personnel by blowing air, effectively preventing external contaminants from entering the maintenance cabin 100. The air shower 500 is particularly suitable for high-voltage combined electrical maintenance requiring a high cleanliness environment. Since dust and particulate matter may have a serious impact on the precision components of the equipment, the air shower 500 ensures that the clean environment inside the cabin is not affected when personnel enter and exit.

[0042] Industrial air conditioner 400 is a built-in industrial air conditioner installed in the front of maintenance cabin 100. It provides a constant temperature and humidity environment inside maintenance cabin 100, preventing adverse effects of external climate change on equipment maintenance. Temperature and humidity control are crucial in the operation and maintenance of high-voltage electrical equipment. Excessive humidity can cause corrosion of equipment components or degradation of insulation performance, while excessive temperature can cause electrical overheating. A constant temperature and humidity environment ensures safety during equipment maintenance and comfort for maintenance personnel.

[0043] The transfer vehicle 700 is used to transfer parts in and out of the maintenance cabin 100. Tracks 130 are installed on the floor of the maintenance cabin 100 along the length of the cabin 100 for the transfer vehicle 700 to travel within the cabin 100. The tracks 130 installed inside the maintenance cabin 100 provide a stable path for the transfer vehicle 700 to travel, facilitating the efficient transfer of parts in and out of the cabin.

[0044] The container-type maintenance cabin for high-voltage combined electrical field maintenance provided in the embodiment of the present application has a maintenance cabin body 100 that adopts a metal square frame structure. The strength and durability of the maintenance cabin body are significantly enhanced, and it is particularly suitable for the maintenance of high-voltage electrical equipment in the field or in harsh environments that require long-term use. Compared with the existing temporary shed structure, the container-type structure is more stable. The inner panels of the maintenance cabin body 100 are metal panels filled with heat-insulating and flame-retardant materials. They can not only effectively isolate dust and pollution from the external environment, but also ensure the safety of the cabin body in high-temperature environments and effectively prevent the spread of fire; the epoxy self-leveling floor is easy to clean and can reduce dust accumulation. At the same time, combined with the sealing effect of the soft door curtain 600, it can provide a more reliable maintenance environment for high-voltage electrical equipment. In addition, by setting up an air shower room 500 to remove dust for entering personnel, the cleanliness of the internal environment of the maintenance cabin body 100 is further ensured. Such a design effectively prevents external dust and impurities from entering the cabin, ensuring the operation and maintenance of high-voltage equipment in a clean environment.

[0045] The maintenance cabin 100 of the embodiment of the present application is a maintenance cabin made of a container. This standard container structure is convenient for overall transportation and on-site lifting, so as to facilitate rapid deployment at different maintenance locations. When in use, it can be easily transported to the maintenance site by ordinary transport vehicles without the need for tedious disassembly and assembly steps, which significantly reduces preparation time and improves the response speed and efficiency of on-site operations. In addition, the air shower room 500 can be moved from the personnel entrance to the maintenance cabin 100 as needed when the entire device needs to be transported, thereby bringing convenience to transportation and use.

[0046] The industrial air conditioner 400 of the embodiment of the present application adopts an industrial embedded air conditioner, which is embedded and installed on the front side of the maintenance cabin 100, and can provide a constant temperature and humidity environment in the cabin, ensure the stability of temperature and humidity during the maintenance process, avoid the adverse effects of external climate on high-voltage electrical equipment, and improve the operating reliability of the equipment; and by setting up a fresh air system 300, the main unit of the fresh air system is installed on the outer wall of the maintenance cabin 100, by purifying the air and constantly replacing the indoor air, it can effectively maintain the cleanliness of the cabin, ensure that the air meets the requirements of the maintenance work, and meet the high requirements of the high-voltage combined electrical maintenance environment.

[0047] The container-type maintenance cabin for high-voltage combined electrical on-site maintenance provided in the embodiment of the present application is equipped with a transfer vehicle 700 and a track 130 for the maintenance cabin 100, which is used for the convenient transfer of parts in and out of the cabin, and can effectively improve the work efficiency during the maintenance process; at the same time, the skylight is set to provide natural light in the cabin, which is convenient for operators to observe and work, and improves the convenience and comfort of maintenance.

[0048] In some embodiments, the container-type maintenance cabin used for on-site maintenance of high-voltage combined electrical equipment in the present application also includes a traveling device 800 installed on the top of the maintenance cabin body 100, and the traveling device includes two guide rails 810 arranged in parallel on the top of the maintenance cabin body 100 and two cranes 820 respectively arranged on the two guide rails 810 for lifting combined electrical components; a distribution box for an external power supply is provided on the front outer wall of the maintenance cabin body 100.

[0049] In this embodiment, a crane device 800 is added to the interior of the maintenance cabin 100 for the container-type maintenance cabin used for on-site maintenance of high-voltage combined electrical equipment in this application, wherein the crane device 800 includes two guide rails 810 arranged parallel to each other on the top of the maintenance cabin 100 and two cranes 820 respectively arranged on the two guide rails 810. During use, it can carry high-voltage combined electrical components of relatively large weight, which facilitates the lifting and movement of the equipment. This design replaces the traditional manual lifting method, reduces the intensity of manual labor, and is particularly important when the high-voltage equipment is large in size and heavy in weight, greatly improving the efficiency of installation and disassembly. A distribution box is provided on the front outer wall of the maintenance cabin 100, which can be used for an external power supply to provide a stable power supply for the equipment in the maintenance cabin. Such a setting facilitates on-site power supply, avoids complicated wiring arrangements, improves the safety and convenience of power management, and is particularly suitable for rapid installation and commissioning during short-term or mobile maintenance.

[0050] In some embodiments, the skylight 110 is a fixed double-glazed window, and the skylight 110 is fixedly mounted on the inspection cabin 100 by bolts for lighting and operation observation.

[0051] The skylight 110 of this embodiment utilizes double-glazed windows, which not only enhance the cabin's thermal and sound insulation but also provide a clear field of view, allowing operators to easily observe the operating status of equipment inside and outside the cabin. Furthermore, the double-glazed windows offer excellent sealing, effectively blocking external contaminants and noise. This is particularly true in high-voltage electrical maintenance environments, where a stable operating environment is crucial to the quality of maintenance work.

[0052] In some embodiments, the fresh air system 300 is a bidirectional flow fresh air system. Using a bidirectional flow fresh air system as the fresh air system 300 for the containerized maintenance cabin of a high-voltage combination electrical system in this application embodiment provides more efficient air replacement compared to a unidirectional flow system. This system can both introduce clean air into the cabin and simultaneously exhaust contaminated air, thereby maintaining cabin air circulation and air quality. This design is crucial for a high-cleanliness work environment and helps quickly remove heat and impurities from the cabin, providing a fresher operating environment.

[0053] In practical applications, the fresh air system 300 should be able to provide sufficient fresh air volume to ensure that the air cleanliness in the cabin meets the relevant clean room standards (level 8 cleanliness), which means that the air volume should reach at least 400-500m 3 / h or higher. At the same time, the fresh air system 300 used must be equipped with a high-efficiency filtration device, such as a HEPA filter, to ensure the cleanliness of the input air. Based on such requirements, optionally, the following model of fresh air system can be used in the embodiment of this application.

[0054] For example, Panasonic full heat exchanger FY-32ZVD2C is used as the fresh air system 300 in the embodiment of the present application, and its air volume is 450m 3 / h, which is suitable for the maintenance cabin requirements of the embodiment of the present application. At the same time, the device supports two-way ventilation, which can ensure air circulation inside and outside the cabin and maintain a clean environment. Moreover, the device can be installed outdoors, which can reduce indoor noise, and the operating noise is low, which meets the quiet requirements of the maintenance environment. At the same time, it is equipped with a high-efficiency filter module to ensure the cleanliness of the input air. Other alternative models can be Yuanda Fresh Air YBJ-450, which has similar air volume (450m 3 / h) and feature a multi-layer filtration system suitable for outdoor installation, offering high purification efficiency and stability. These models meet high air cleanliness and noise control requirements and are suitable for outdoor installation, making them ideal for the maintenance cabin environment described in this application.

[0055] In some embodiments, the maintenance cabin 100 is equipped with two transfer carts 700. One transfer cart 700 is set on the track 130 inside the maintenance cabin 100, and another transfer cart 700 is set outside the maintenance cabin 100. Both transfer carts 700 are electrically driven transfer carts, and the wheels of the transfer carts 700 are load-bearing universal wheels with brakes.

[0056] Compared to manual handling, the use of an electrically driven transfer vehicle significantly improves work efficiency while reducing the risk of misoperation and equipment damage during handling. The wheels of the transfer vehicle 700 utilize heavy-duty universal wheels with brakes, enabling precise positioning of the vehicle when needed, preventing safety incidents and ensuring safe operation. Furthermore, this embodiment is equipped with two electrically driven transfer vehicles, one located inside the maintenance cabin 100 and the other outside, enabling rapid transfer of equipment between the cabin and outside, thereby improving operational efficiency.

[0057] In some embodiments, a bracket 140 is provided on the floor of the maintenance cabin 100 in the inner area of ​​the personnel entrance 120 , which allows the air shower room 500 to move in and out of the maintenance cabin 100 from the personnel entrance 120 . A bracket 140 is set in the inner area of ​​the personnel entrance and exit 120. When in use, the air shower room 500 can be moved from the personnel entrance and exit 120 to the maintenance cabin 100 as needed. The setting of the bracket 140 facilitates the movement of the air shower room 500 to avoid damaging the floor of the maintenance cabin 100. Moreover, after the maintenance cabin 100 is transported to the working environment site, the air shower room 500 on the mobile bracket 140 can be moved toward the personnel entrance and exit 120 on the bracket 140, and the air shower room 500 can be moved out of the maintenance cabin 100 and located outside the personnel entrance and exit 120, so that the air shower room 500 can be used normally to remove dust for personnel. This design improves the flexibility of the use of the air shower room 500, and the air shower room 500 can realize effective dust removal operations, thereby enhancing the cleanliness of the cabin.

[0058] In some embodiments, an outer door 510 is provided at the front end of the air shower room 500, an inner door 520 is provided at the rear end of the air shower room 500, and slide rails 530 are arranged at intervals on the left and right sides along the front-to-back direction at the bottom of the air shower room 500. A placement rack 540 for placing the air shower room 500 is also provided on the ground in front of the personnel entrance and exit 120 of the maintenance cabin 100, and a personnel entrance and exit door 121 that can be opened and closed is also installed at the personnel entrance and exit 120.

[0059] During use, the air shower 500 is provided with an outer door 510 and an inner door 520 at the front and rear, respectively. This double-door design further improves the air shower 500's sealing performance and prevents contaminants from entering the inspection cabin 100 along with personnel. The outer door 510 and the inner door 520 control personnel entry and exit, ensuring that the external environment does not affect the air quality within the cabin during operation. Moreover, the slide rails 530 are arranged along the front-to-back direction of the bottom of the air shower room 500, which can protect the air shower room 500 when it is moved. When in use, the air shower room 500 can be moved on the bracket 140 by the slide rails 530 to avoid wear of the bottom plate of the air shower room 500 and damage to the main structure of the air shower room 500 when the air shower room 500 moves. Such a design not only facilitates moving the air shower room 500 into the maintenance cabin body 100 when transporting the container-type maintenance cabin of the embodiment of the present application, but also when the environment in which the container-type maintenance cabin of the embodiment of the present application is placed is relatively limited, the air shower room 500 can also be flexibly moved to the inside of the maintenance cabin body 100 as needed, thereby saving more space outside the maintenance cabin body 100. A placement rack 540 is set at the personnel entrance and exit 120 to facilitate the fixation and placement of the air shower room 500 outside the maintenance cabin 100. The personnel entrance and exit door 121 can be closed after the air shower room 500 is moved to the bracket 140 in the maintenance cabin 100, so that the entire maintenance cabin 100 can be transported after the air shower room 500 is moved into the cabin. When the air shower room 500 needs to be moved out again, the personnel entrance and exit door 121 can be opened, and the personnel entrance and exit 120 can be opened to move the air shower room 500 out of the maintenance cabin 100 through the personnel entrance and exit 120, thereby providing a more convenient passage for maintenance personnel and ensuring that the cleanliness of the internal environment of the maintenance cabin 100 is effectively controlled when personnel enter and exit.

[0060] In some embodiments, a transition platform 900 for receiving a transfer vehicle 700 is provided on the ground outside the double-leaf door 200 at each end of the maintenance cabin 100. This facilitates the transfer vehicle 700's entry and exit from the maintenance cabin 100, ensuring smooth connection between equipment inside and outside the cabin. Furthermore, the use of the transition platforms 900 at the left and right ends of the maintenance cabin 100 is particularly suitable for transporting high-voltage equipment, ensuring that the access sections on both ends of the maintenance cabin 100 are not easily damaged, thereby improving the safety of heavy electrical equipment when entering and exiting the maintenance cabin 100.

[0061] In some embodiments, the soft door curtain 600 is connected to the inspection cabin 100 on the inside of the door frame of the double-leaf door 200 using magnetic velcro. The soft door curtain 600 features a split-leaf structure and is attached in the middle with magnetic velcro, providing a temporary seal between the inspection cabin 100 and the double-leaf door 200 when the double-leaf door 200 is open. The soft door curtain 600 is connected to the inspection cabin 100 via magnetic velcro, providing a flexible seal that maintains a clean environment when the double-leaf door 200 is closed and provides a temporary seal during equipment docking when the double-leaf door 200 is open. This simple and effective design significantly reduces the ingress of contaminants caused by door opening, ensuring cabin cleanliness and operational safety. In practical applications, the soft door curtain 600 can optionally be made of canvas with a filament-coated plastic sheeting on the inside. Alternatively, a soft door curtain made of PVC material can be used, securely connected to the inspection cabin 100 on the inside of the double-leaf door 200 via hooks to facilitate installation and removal of the soft door curtain 600.

[0062] The containerized maintenance cabin of the embodiment of the present application is mainly used in the on-site maintenance of high-voltage combined electrical equipment, providing a clean, safe, constant temperature and humidity working environment to ensure the normal maintenance and operation of the equipment on site. The working principle of this device is based on the synergy of the fresh air system, industrial air conditioning, air shower room, transfer vehicle and driving device to achieve efficient on-site maintenance of equipment and personnel. The specific working principle is as follows:

[0063] First, the maintenance cabin 100 is the foundational structure of the entire device. Designed like a container, its interior panels are filled with thermally insulating and flame-retardant materials, ensuring the device's robustness and safety in harsh field conditions. Equipment enters and exits the maintenance cabin 100 via a double-leaf door 200, which is fitted with a soft curtain 600 inside to provide a temporary seal and prevent contaminants from entering. This sealing design maintains a clean environment within the cabin during equipment entry and exit, protecting the equipment from contamination.

[0064] When maintenance personnel enter the inspection cabin 100, they first pass through the air shower 500. This air shower 500 effectively removes dust particles that have entered the personnel's bodies by blowing air, preventing external dust and impurities from entering the cabin, thereby ensuring high cleanliness within the cabin. This is particularly important for the maintenance of high-voltage combination electrical equipment. Dust or particulate matter can affect the electrical performance of the equipment and even cause malfunctions, so maintaining a clean environment within the cabin is crucial. In addition, the air shower 500 can be flexibly moved to the interior of the inspection cabin via the bracket 140, making dust removal more flexible and further improving the dust removal effect of the inspection cabin.

[0065] The air inside the maintenance cabin 100 is purified and circulated by the fresh air system 300. The main unit of the fresh air system 300 is mounted on the cabin's outer wall, enabling a bidirectional air flow exchange between the cabin's interior and exterior. Outside air is efficiently filtered before entering the cabin, ensuring a clean air supply, while contaminated air is discharged through the exhaust vents. This bidirectional air flow design effectively reduces dust and harmful gases in the air, ensuring a fresh and healthy environment within the cabin. This is particularly important during long equipment maintenance operations, ensuring that operators can work in a comfortable environment.

[0066] The Industrial Air Conditioner 400 is embedded in the front of the cabin, providing a constant temperature and humidity environment. Equipment operation has strict temperature and humidity requirements. Excessive humidity can degrade the equipment's insulation performance, while temperature fluctuations can cause overheating and other problems. The Industrial Air Conditioner 400 maintains stable temperature and humidity conditions within the cabin, ensuring safe equipment operation and smooth maintenance.

[0067] Parts transfer during maintenance is accomplished using an electrically driven transfer cart 700. This cart moves along a pre-set track 130 within the cabin, enabling smooth transfer of large components from outside to inside. This reduces manual handling and improves maintenance efficiency. The cart 700 is equipped with brakes and universal wheels to ensure safe movement and precise docking at the desired location, preventing collisions or damage. A transition platform 900 outside the cabin further facilitates the connection between internal and external equipment, ensuring smooth and efficient component transfer.

[0068] A crane 800 is installed at the top of the maintenance cabin 100 for hoisting large high-voltage electrical components. The crane 820 moves smoothly on guide rails 810, enabling rapid loading and unloading of equipment and improving the convenience and safety of maintenance. This design is particularly suitable for installing and removing large and heavy equipment, reducing manual labor and significantly improving work efficiency.
