[0002] Container shipping is an important mode of transport in international multimodal transport, boasting advantages such as high standardization, excellent sealing, low damage rate, intensification, large-scale operation, low cost, and high quality, significantly improving the safety and efficiency of cargo transportation. With the increasing demand for equipment adaptable to special environments in the industrial sector, containers are gradually extending from transport carriers to "equipment integration carriers." Especially in industrial projects operating in harsh, low-temperature environments, containers adapted to air compressor units need to possess characteristics such as insulation, resistance to extreme weather (e.g., severe sandstorms), and ease of transport and handling.

[0003] In the prior art, Chinese patent application number 202120965250.4 discloses a double-unit container house. This double-unit container house achieves the assembly and splicing of the left and right container bodies through container sealing components. Although it can increase the space and solve the sealing problem at the splicing point, it has obvious shortcomings: it is only designed for civilian housing scenarios and does not consider the adaptation needs of harsh environments such as low temperature and snow in industrial project sites, and cannot resist the impact of extreme low temperature on internal equipment; at the same time, it has not optimized the structure for the transportation and hoisting of large equipment such as industrial air compressor units. The extra-long and extra-wide dimensions can easily lead to transportation difficulties, and it lacks the adaptation structure for equipment installation and maintenance, resulting in poor practicality and failing to meet the usage requirements of industrial low-temperature environment air compressor units.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] refer to Figures 1-2 As shown, a non-standard containerized air compressor station for low-temperature environments includes a container shell 5 composed of a container shell on side A and a container shell on side B, wherein the container shell on side A and the container shell on side B are a split structure; it also includes an air compressor system, an after-treatment system, a constant temperature system, and an electrical control system, all of which are located within the internal space enclosed by the container shell on side A and the container shell on side B; To address the shortcomings of existing double-sided containers, which suffer from "excessive length and width leading to transportation / lifting difficulties," the container shell is designed as a split structure with A and B sides, avoiding the problem of the overall size exceeding the transportation and lifting limits. Based on the requirement of "integrated equipment deployment," the air compressor system providing air volume and pressure, the post-treatment system for cooling and drying, the constant temperature system for temperature control, and the control core of the electrical control system are integrated into the internal space enclosed by the A and B side shells, forming a "functional closed loop" and avoiding the interference of the external environment due to the dispersed installation of equipment.

[0018] Solving transportation pain points: The split structure breaks through the limitations of overall size, adapts to conventional transportation tools such as trucks and cranes, and reduces transportation costs and difficulties; Enhancing environmental adaptability: The equipment is integrated into a closed shell, which initially isolates it from harsh environments such as low temperatures and snow, laying the foundation for subsequent insulation and temperature control design; Simplified on-site deployment: No need to build a separate equipment installation frame on-site; the system can be put into operation as soon as the shell is assembled, shortening the project implementation cycle.

[0019] In a further embodiment, the top of the container shell 5 is a sloping roof structure 4 that is protected from rain and snow. The container shell on side A and the container shell on side B are detachably connected by a snap-fit ​​structure 2, and a sealing structure is provided at the connection between the container shell on side A and the container shell on side B.

[0020] The top adopts a rain and snow sloping roof structure, which uses gravity to allow rain and snow to slide off naturally, preventing rain and snow from accumulating and damaging the shell or seeping into the interior; the snap-on structure 2 enables the detachable connection of the shells on the A and B sides, and the interlocking characteristics of the mechanical snap-on ensure a stable splicing, while simplifying the on-site assembly process; Sealing structures such as sealant and rubber gaskets are installed at the joints to block air convection and rain / snow penetration through the gaps in the shell, thus maintaining a stable internal environment.

[0021] Protected from rain and snow damage: The sloping roof design prevents shell corrosion and structural deformation caused by rain and snow accumulation, thus extending the service life of the container; Improved splicing efficiency: Snap-fit ​​connections eliminate the need for complex welding or bolt tightening, shortening on-site splicing time and reducing labor costs; Enhanced thermal insulation: The sealed structure prevents cold air from entering the interior through gaps, reducing the energy consumption of the constant temperature system, while also preventing rain and snow from seeping in and damaging the internal equipment.

[0022] In a further embodiment, the container shell 5 includes a base frame 8 and a top beam. Both the base frame 8 and the top beam are equipped with lifting corner brackets 11, and the positions of the lifting corner brackets 11 are adapted to the center of gravity of the container shell 5.

[0023] The position of the center of gravity of the container shell and its internal equipment is simulated by static simulation to ensure that the lifting corner brackets are set at the force balance point corresponding to the center of gravity. The base frame and top beam, as the load-bearing core, are made of high-strength materials such as Q235 steel, and together with the lifting corner brackets, they form a lifting structure with "multi-point uniform force" to avoid excessive force on a single point, which would cause the shell to deform.

[0024] Ensuring lifting safety: During lifting, the shell is subjected to uniform force, eliminating the risk of tilting or tipping over, and protecting internal precision equipment such as air compressors and electrical control cabinets from collision damage; Extending structural lifespan: The load-bearing design of the base frame and top beam, along with the balanced layout of the hoisting corner fittings, avoids localized stress concentration in the shell during hoisting, reducing structural fatigue damage; Adaptable to various scenarios: It is compatible with cranes of different tonnages, eliminating the need for additional customized lifting tools and improving on-site lifting flexibility; In a further embodiment, the top, bottom, and sides of the container shell 5 are all double-layered hollow structures, and the interior of the double-layered hollow structures is filled with rock wool 9.

[0025] The top, bottom, and sides of the shell are designed with a double-layer hollow structure, which utilizes the low thermal conductivity of air to form an "air insulation layer" to slow down the transfer of heat between the inside and outside. The double-layer structure is filled with rock wool, which relies on the characteristics of rock wool such as "low thermal conductivity to resist low temperature and porous structure to absorb noise" to achieve both heat preservation and noise reduction functions, meeting the dual requirements of temperature and noise for equipment operation in low-temperature environments.

[0026] Resisting extreme low temperatures: The double-layer structure and rock wool filling can isolate the internal environment from the outside -40°C wind and snow environment, ensuring that the internal temperature meets the operating requirements of equipment such as air compressors, typically 5-15°C. Reduce operating noise: Rock wool absorbs the noise generated by the operation of equipment such as air compressors and fans, avoiding noise pollution to the surrounding environment and meeting the environmental protection standards for industrial projects; Reduced energy costs: Good insulation reduces the heat replenishment requirements of the constant temperature system, indirectly reducing electricity consumption.

[0027] In a further embodiment, a sub-base frame 10 is fixedly installed on the base frame 8 of the container shell 5, and the sub-base frame 10 is provided with tapping holes or nuts fixed by back welding; a hand-operated hoist is fixedly installed on the top crossbeam of the container shell 5.

[0028] A secondary base frame is installed on the base frame, providing standardized installation interfaces through tapping holes or back-welded nuts, allowing equipment such as air compressors and post-treatment systems to be directly fixed with bolts, preventing equipment displacement; a hand-operated hoist is installed on the top crossbeam, utilizing the pulley principle to move the internal equipment manually without relying on large hoisting equipment.

[0029] Ensure equipment stability: The standardized installation interface of the subframe securely fixes the equipment, preventing it from shifting during transportation and operation and reducing the risk of failure; Simplified operation and maintenance process: When maintaining equipment, the position of the equipment can be easily adjusted by using a hand chain hoist, such as disassembling an air compressor for repair, without the need to call a crane, reducing operation and maintenance costs and time; Compatible with non-standard equipment: The design of the tapping hole and back-welded nut can be flexibly adjusted according to the equipment installation hole position, supporting non-standard customization needs of different models of air compressors and post-treatment systems.

[0030] In a further embodiment, both ends of the container shell 5 are provided with a mother door 7, which includes a mother door and a daughter door that cooperate with each other, and the mother door is fitted with an air intake filter electric louver 6.

[0031] The mother-daughter door adopts a combination design of "large-size mother door + small-size daughter door". The size of the mother door is suitable for the entry and exit of large equipment such as air compressors, while the size of the daughter door is suitable for personnel passage. The mother door is equipped with an air intake filter motorized louver, which realizes air circulation through the ventilation channel of the louver, while using the filter to filter dust and impurities in the air to prevent pollutants from entering the interior.

[0032] Adaptable to different scenarios: During equipment installation, the main door is opened to facilitate the entry and exit of large equipment; during routine maintenance, only the secondary door is opened to reduce heat exchange between the inside and the outside, thereby reducing the energy consumption of the constant temperature system. Protect internal equipment: The electric louvered air intake filter blocks dust and impurities from entering, preventing them from adhering to the air compressor filter element and the dryer of the after-treatment system, thus extending the life of vulnerable parts and reducing malfunctions. Enhanced operational safety: The compact size of the sub-doors makes them easy to open and close, eliminating the need for frequent operation of the large door and reducing operational risks such as collisions caused by excessive door weight.

[0033] In a further embodiment, the constant temperature system includes a heater and a three-way valve. The heater is fixedly installed on the inner side wall or top of the container shell 5. The input end of the three-way valve is connected to the heat dissipation outlet of the air compressor system, and the two output ends of the three-way valve are respectively connected to the internal space of the container shell 5 and the external environment.

[0034] The heater actively replenishes heat through radiation, maintaining the internal temperature even in extremely low external temperatures, such as -40°C. The three-way valve connects to the heat dissipation outlet of the air compressor system, utilizing the waste heat generated during the operation of the air compressor: when the internal temperature is low, the three-way valve directs the waste heat to the internal space to achieve "waste heat recovery"; when the internal temperature is high, it directs the waste heat to the external environment to avoid excessive temperature affecting the operation of the equipment.

[0035] Precise temperature control: The combination of active heat replenishment heater and passive waste heat recovery ensures that the internal temperature is stable within the suitable operating range of 5-15℃, avoiding equipment performance degradation caused by temperature fluctuations, such as insufficient air compressor discharge. Energy saving and consumption reduction: Recycling and utilizing waste heat from air compressors reduces the start-up frequency of heaters, lowers electricity consumption, and meets the requirements of green industry; Improve system reliability: The constant temperature environment avoids problems such as component freezing due to low temperature, such as icing of pipelines in the post-treatment system and increased lubricating oil viscosity affecting the operation of the air compressor, thus extending the overall life of the equipment.
