Description

Technical Field

[0001] This invention relates to the field of modular container applications, and in particular to the modular container assembly technology used in large-scale tea primary processing plants that require multiple containers to be combined. Specifically, it relates to the power connection device and connection method between modular tea primary processing plant containers. Background Technology

[0002] Currently, the processing capacity of primary tea processing plants shows a clear hierarchical distribution, with 30% having a processing capacity of less than 1 ton, 65% having a processing capacity of around 2-3 tons, and only 5% having a processing capacity of 15-20 tons. The overall processing level, processing capacity, and processing quality are all at a low level, making it difficult to ensure the uniformity, cleanliness, and standardization of raw materials.

[0003] Against this backdrop, tea companies are eager to build standardized primary processing plants to achieve standardization and cleanliness in the processing of tea raw materials, and relevant policies, regulations, and standards have been introduced. Meanwhile, standardized and regulated primary processing plants with automated production lines, such as Xiaoxinzhai, have emerged in the market, boasting excellent production results, superior processing quality, high processing efficiency, and a high level of homogenization. However, the promotion of these primary processing plants faces many obstacles, including difficult land approval processes, lengthy approval times, long construction periods, high construction costs, and large land areas required.

[0004] On the other hand, the demand for whole-leaf tea from emerging tea beverage companies is increasing year by year, and they have certain requirements for tea quality. Downstream food and beverage industries have a huge demand for tea leaves; tea beverage companies such as Nongfu Spring, Wahaha, and Bawangchaji require 3,000-5,000 tons of dried tea leaves annually, and also have personalized requirements for the aroma, color, appearance, and internal components of the tea leaves. However, the traditional single-production-line model of primary processing plants cannot meet the diverse processing needs of food and beverage companies, nor can it quickly and flexibly change production lines. Therefore, building a primary processing plant that can reduce construction costs, be quickly built, shorten the land use approval cycle, reduce approval difficulties, and has a flexible combination mode has become a market trend.

[0005] Modular construction involves combining various units to quickly generate production capacity, meeting both standardized production and rapid deployment needs. This is achieved by organizing processing operations into units, classifying these units into modules, and then flexibly combining functional units selected from a unit model library based on application scenarios. Finally, by horizontally extending and crisscrossing specific-shaped modular systems, modular systems of varying scales can be formed to rapidly meet user construction requirements.

[0006] However, the rich variety of tea types and the diversity of processing techniques mean that each production line may have unique process and layout requirements. This directly leads to the difficulty in following a uniform square or other conventional structural pattern for the arrangement of the modular units, often requiring irregular arrangements based on specific processing needs. This irregularity not only increases the difficulty of the initial planning and design but also restricts space utilization during actual construction, potentially resulting in problems such as unreasonable gaps between units and narrow operating passages, affecting the convenience of production operations.

[0007] The installation of power transmission between modular units is particularly problematic. Because the layout of the modular units and the direction and sequence of connecting circuits need to be precisely designed in advance, this places extremely high demands on the designers' professional skills and familiarity with tea processing techniques. Even a slight deviation in the design process can lead to incorrect docking of the modular units during subsequent installation, preventing the proper laying of power transmission lines. Furthermore, the high dependence on the specific characteristics of each modular unit during installation means that each unit has a unique location and connection method. Misuse of any single unit can trigger a chain reaction, causing the entire power system to malfunction and requiring significant time and manpower for troubleshooting and adjustments.

[0008] The lack of flexibility in disassembling and reusing modular shelters after assembly severely impacts their reusability and applicability. When production demands change, requiring adjustments to the scale of the primary manufacturing plant or the types of products processed, the original modular shelter configurations often fail to meet the new requirements. Because different configurations result in variations in connections and power transmission paths between shelters, reassembling disassembled shelters may necessitate large-scale modifications to the connection structures and power lines. This not only increases the cost and time of the modifications but may also damage the shelters themselves due to improper handling during the process, reducing their lifespan.

[0009] The method of pre-drilling connecting channels at predetermined locations on the modular shelter structure and manually wiring the electrical connections has several drawbacks. First, the accuracy of the pre-drilled locations is crucial. If the pre-drilled locations do not match the actual connection requirements, re-excavation is necessary, which not only compromises the structural integrity of the shelter but also increases construction costs and time. Second, manual wiring is not only inefficient, but the quality of the wiring is highly dependent on the skill level of the operators, easily leading to problems such as loose connections and poor contact, posing a potential threat to the safe and stable operation of the power system. Furthermore, improper handling of the excavated connecting channels can allow dust and moisture to enter the shelter, affecting the cleanliness of the tea processing environment.

[0010] The timing of power deployment and connection during the docking of the modular units also presented numerous challenges to the construction. If power deployment and connection were carried out after the modular units were hoisted and docked, operators would have to work between the already docked units, resulting in limited space, high operational difficulty, and significantly reduced construction efficiency. Conversely, if the electrical connections between the units were established beforehand, excess cables lacked effective storage methods during hoisting, easily becoming tangled and dragged, affecting not only the smoothness of the hoisting operation but also potentially loosening connection points due to cable tension. Furthermore, the risk of cable compression during hoisting was extremely high, potentially damaging the cable insulation and causing short circuits and other safety accidents. In addition, if the waterproofing of the connection points was not properly addressed, leakage and short circuits were highly likely in the humid tea processing environment, seriously threatening production safety and equipment lifespan.

[0011] Using existing connector parts can lead to errors and complicated procedures due to male / female compatibility issues. Furthermore, existing universal connectors present significant difficulties in installation and hoisting. During installation, the connector's structural design is not well-suited to the modular shelter's connection requirements, potentially requiring special tools or complex procedures for securing it, greatly reducing installation efficiency. During hoisting, the connection between the connector and the shelter lacks stability, making it prone to detachment or displacement due to swaying. Additionally, the connector's insufficient length and lack of redundancy severely limit cable adjustment during shelter docking. Even slight deviations in the shelter's position during installation and hoisting can prevent successful connection due to insufficient cable length, necessitating readjustment of the shelter's position or cable modification, further increasing operational complexity.

[0012] More importantly, during the long-term operation of the primary processing plant, vibrations or misalignments inevitably occur between the modular units due to equipment operation and external environmental factors. Because the connectors lack redundant design, the cables are under tension, and vibrations or misalignments are directly transmitted to the connectors, causing them to be subjected to continuous tensile or shear forces. Over time, this can easily lead to problems such as internal wiring breakage, loosening of contacts, or damage to the outer casing, affecting not only the stability of power transmission but also potential safety hazards such as electrical leakage, threatening the safe production of tea processing. Summary of the Invention

[0013] To address the aforementioned issues, this invention provides a power connection device and method for connecting modular tea processing cabins. This device, through standardized interface specifications, redundant cable design with retractable coils, convenient assembly and disassembly structure, and waterproof sealing measures, solves the shortcomings of traditional connectors in terms of adaptability, flexibility, stability, and safety, and achieves efficient and reliable power connection between modular cabins.

[0014] This power connection device is applied to a modular container, meeting the processing characteristics of primary tea processing plants. Primary tea processing involves a wide variety of tea types and processing techniques, requiring highly flexible production line layouts. The container needs to be able to be flexibly combined horizontally, vertically, or in a combination of both, according to the processing flow of different teas (such as roasted green tea and sun-dried green tea). The design of the power connection slots in the device ensures precise alignment of the container with the power connection slots under various connection methods. The cooperation between the connection cable and the cable reel provides cable redundancy, accommodating potential positional deviations during container assembly, ensuring a stable power supply under different processing techniques, and highly adapting to the diverse production needs of primary tea processing plants. The power connection method of this invention enables the rapid construction of primary tea processing plants, and the modular container is a key way to achieve this goal. The quick-plug mechanism of the power connection device makes the installation and dismantling of the modular container convenient and efficient, reducing construction time and labor costs in the power connection process; the standardized wiring plugs avoid connection errors and improve construction efficiency; the cable reel storage function ensures operational safety and convenience during hoisting. All of these are closely related to the needs of rapid construction and efficient production of tea primary processing plants, and help promote the application of modular modular containers in the field of tea primary processing.

[0015] Specifically, the present invention is implemented as follows:

[0016] A power connection device between modular tea processing workshop cabins, used for power connection between sealed and assembled cabins, includes: a power connection slot, set on the side wall of at least one structural beam of the cabin, recessed inward to form an inner cavity structure, and equipped with a wiring socket for connecting the cabin's cables; the position of the power connection slot is such that when the cabins are installed in a horizontal or vertical manner from various directions, the positions of their respective power connection slots correspond to each other; a plate, whose external dimensions match the shape and dimensions of the power connection slots on the cabins, is used to seal the power connection slots at the edge area of ​​the slot openings, and when two adjacent cabins are connected, the corresponding two power connections... The connecting groove is pressed tightly against the same plate; the connecting cable includes two identical connectors at both ends, located on the inner and outer sides of the plate respectively, and is stored in a cable reel; the connectors are used to connect to the connectors in the power connection groove of the container; the cable reel is installed on the inner side of the plate and is used to wind up the connecting cable. The cable reel has two openings, one facing the inner side of the plate and the other on the plate facing the outer side. Each end of the connecting cable extends from one opening, and the connectors at both ends can be pulled out and stored in the cable reel when there is no external force; after the plate is installed, the cable reel can be accommodated in the power connection groove of the container.

[0017] Preferably, an elastomeric waterproof ring is arranged in a ring on both sides of the plate near the edge, and a waterproof ring is provided on the inner wall of the hole through which the docking cable passes through the plate. The docking cable passes through the waterproof ring and extends from the other side of the plate. The waterproof ring fills the space between the hole and the cable sheath of the docking cable.

[0018] Preferably, mounting positioning holes and quick-insertion / quick-extraction mechanisms are respectively provided on both sides of the power docking slot on the structural beam of the container. On the inner side of the plate facing the cable reel, there are two protruding pins on both ends. The position and length of the pins are adapted to the position and depth of the mounting positioning holes, so that the pins at both ends can be inserted into their respective mounting positioning holes. The quick-insertion / quick-extraction mechanism can stabilize the inserted pins.

[0019] Preferably, the quick-insertion and quick-extraction mechanism includes a transverse groove disposed inside the structural beam, perpendicular to the mounting positioning hole, a sliding locking block installed in the transverse groove, and a transverse spring fixed to the bottom of the transverse groove. The transverse groove communicates with the mounting positioning hole, and the sliding locking block extends into the mounting positioning hole through the support of the transverse spring. A tenon is provided on the side of the pin rod located on the side of the transverse groove, so that when the pin rod is inserted into the mounting positioning hole, the sliding locking block can be embedded in the tenon of the pin rod under the action of the transverse spring to lock the pin rod. An unlocking lever is fixedly connected to the sliding locking block and exposed on the outer surface of the structural beam. The unlocking lever is located in the transverse groove. When the unlocking lever is pulled laterally in the opposite direction, it can drive the sliding locking block to move laterally in the transverse groove to compress the transverse spring, so that the sliding locking block is disengaged from the tenon of the pin rod to unlock the pin rod.

[0020] Preferably, the sliding lock block has a ramp on its side face facing the mounting positioning hole, with the lower slope of the ramp facing the entrance of the mounting positioning hole; the end of the pin is an arc-shaped structure; and friction stripes are provided on the outer surface of the unlocking lever.

[0021] Preferably, the connector includes several sockets for connecting to the cable line, the sockets being integrated on an insulator to form a cylindrical connector structure, and a threaded cap surrounding the connector structure. The connector is composed of several pins that are adapted to the sockets, and an external threaded sleeve adapted to the threaded cap is provided around the pins, so that when the pins are inserted into the sockets, they are tightened onto the external threaded sleeve by the threaded cap, making the connection tight and stable.

[0022] Preferably, a sliding cover plate that can be vertically pulled out is installed above the opening of the power connection slot. The sliding cover plate is pulled out vertically along the vertical grooves provided on both sides of the slot to cover the opening of the power connection slot when not in use.

[0023] Preferably, the aspect ratio of the modular container is 1:2, and two electrical docking slots are provided on the surface of each long side structural beam, and one electrical docking slot is provided on each side of each wide side structural beam; and the distribution of the electrical docking slots is such that when the two modular containers are docked at the front and rear ends, docked on the long sides in parallel directions, or docked in a vertical direction, the two electrical docking slots on the opposite surfaces can be aligned with each other.

[0024] On the other hand, the present invention also provides a docking method for the electrical docking device between modular tea primary processing workshop cabins, comprising the following steps:

[0025] Step S1: According to the combination method of the modular cabin structure plan, for two adjacent modular cabin modules A and B that need to be connected to the circuit, with the position of the power docking slot on the opposite side of the structural beam as the target, use hoisting equipment to suspend modular cabin module B close to modular cabin module A and pause when leaving a working gap.

[0026] Step S2: Insert a plate into the gap and place it between two opposing power docking slots. Pull out the two wiring plugs from the cable reel and connect them to the wiring sockets in the power docking slots of the cabin module A and cabin module B on both sides of the plate.

[0027] Step S3: Fasten the plate body onto the power docking slot of the container module A and cover the power docking slot;

[0028] Step S4: Continue to move the modular container module B to narrow the working gap until the modular container module B is close to the modular container module A. At this time, the power docking slot of the modular container module B is tightly connected to the plate.

[0029] Step S5: Install connectors between the structural beams of modular cabin module A and modular cabin module B to complete the electrical and structural connection of the two adjacent modular cabin modules.

[0030] Step S6: Install the modular cabin module C with modular cabin module A or modular cabin module B according to the above steps to achieve circuit connection; similarly install the remaining modular cabin modules to finally achieve the power connection of the entire modular cabin system; wherein, the modular cabin modules can be connected horizontally or vertically, or both horizontally and vertically, and the structural beams on the docking surface all have power docking slots with corresponding positions.

[0031] Preferably, during disassembly, the connecting parts between the modular cabin modules A and B are removed, and the modular cabin module B is lifted and moved using hoisting equipment, so that the disassembly is stopped when the gap between them reaches the working gap.

[0032] Remove the connector of the docking cable from the connector of the shelter module B; remove the plate installed on the shelter module A, remove the connector of the docking cable from the connector of the shelter module A; remove the plate.

[0033] Continue to lift and move modular module B using hoisting equipment, i.e., separate the modular module. The disassembly of the remaining modular modules shall be carried out in the same manner.

[0034] The modular shelter has a length-to-width ratio of 1:2, and each long side of the structural beam has two electrical connection slots, while each wide side of the structural beam has one electrical connection slot on each of its two sides. The distribution of the electrical connection slots ensures that when two modular shelters are connected in a straight line, parallel long sides, or vertical cross-section, the two electrical connection slots on opposite sides can be aligned with each other. The electrical connection slots in one set of interconnected modules are electrically connected to each other through an electrical connection device.

[0035] The working principle of this invention is as follows: This device constructs a standardized electrical connection through the synergistic action of auxiliary structures such as the electrical docking slot, plate, docking cable, cable reel, and waterproof and quick-installation mechanisms. The electrical docking slot is pre-installed on the side wall of the modular housing structure beam. Its position can be designed according to the modular housing's length-to-width ratio of 1:2 and possible docking directions, including transverse, longitudinal, and a combination of both, ensuring precise alignment of the docking slots of adjacent modular housings during docking in any direction, providing a unified benchmark for the electrical connection. The plate's dimensions cover the electrical docking slot, serving both as a cover to bidirectionally seal the slot and as a carrier to install the cable reel. Simultaneously, it cooperates with the modular housing's quick-plug mechanism via pins on both sides, enabling rapid fixing and disassembly. The docking cable has standardized connectors at both ends, precisely compatible with the connectors within the docking slot. The cable reel stores the cable and provides redundant length, allowing for minor positional deviations during modular housing docking, preventing cable tautness, and also storing the cable during hoisting to prevent tangling or damage. The auxiliary protection structure includes an elastomeric waterproof ring at the edge of the panel and a waterproof ring at the cable penetration point to seal and prevent dust and moisture from entering; the quick-connect and quick-release mechanism enables the panel to be quickly locked / unlocked from the container, improving operational efficiency.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] (1) The present invention standardizes the plug and socket specifications. The plug is a cylindrical structure with multiple sets of sockets integrated with a threaded cap. The socket is a pin structure with an external threaded sleeve. The pin and the socket are connected to conduct electricity. The screw is tightened mechanically to achieve universal docking between different cabin modules. This design enables each cabin to be a socket design. Only one set of the power docking device of the present invention is needed between cabins to achieve connection and installation. It does not limit the combination form of cabins, meets the production line layout of different tea processing equipment, and flexibly adapts to the diversity of tea processing. Through the preset slot and unified interface, any combination form can achieve power docking, ensuring power connection, retaining flexibility and ensuring standardization.

[0038] (2) The redundant cable and reel storage design effectively avoids installation deviations and usage risks. The docking cables are stored in the reel and can be pulled out freely as needed for docking. This adapts to the gaps during the docking of the modular container. Even if there is a slight positional deviation in the modular container, the redundant cables can compensate for the error and prevent the cables from being too tight. After docking, the cables are automatically retracted to prevent them from being exposed. This avoids the problems of hoisting obstruction or insulation damage caused by traditional "cable dragging and tangling". At the same time, the redundant design reduces the requirements for hoisting accuracy. Combined with the integrated plate with the quick-plug mechanism, it greatly improves the docking efficiency of the modular container. The redundant cables avoid a tight state. When the modular container vibrates or is slightly misaligned due to equipment operation, the cables can buffer the tension and prevent the joints from breaking under stress. The mechanical fixation of the threaded caps ensures that the plug and socket are rigidly fitted, avoiding poor contact caused by vibration.

[0039] (3) It can meet the requirements of long-term stable and safe use. The environment of the tea primary processing plant is humid. Traditional power interfaces are prone to leakage and short circuits, and equipment vibration can easily cause the joints to loosen. The present invention arranges an elastic waterproof ring around the edge of the plate. When the container docks with the container, it is pressed and sealed by the container. A waterproof ring is set at the cable penetration point to fill the gap between the cable and the hole, forming a further sealing protection for the cable gap and reducing the intrusion of water vapor and dust.

[0055] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0056] Example 1: The modular tea processing cabin power docking device in this example is designed with functional components focused on "flexible docking, quick assembly and disassembly, sealed safety, and adaptability to tea processing scenarios." The power docking slot 12, serving as the "reference interface" for power connection of cabin 1, is recessed into the inner cavity structure of the side wall of the structural beam 11 of cabin 1, and contains a wiring socket 15 for connecting to the internal cables of cabin 1. Distributed according to the cabin 11:2 length-to-width ratio: two slots on the long side and one on the wide side, ensuring that the power docking devices of adjacent cabins 1 can be aligned when docking laterally, longitudinally, or in both directions. As the physical reference for power connection, its position design covers all possible combinations of cabins 1, including front-to-rear straight docking, parallel docking along the long side, and vertical turning docking, ensuring that the docking slots of adjacent cabins 1 can be aligned "face-to-face" when spliced ​​in any direction, providing a prerequisite for power connection. The built-in wiring socket 15, with pins and external threaded sleeves 232, is the external power output / input port of cabin 1, which, through cooperation with the plug of the docking cable 22, enables circuit conduction between adjacent cabins 1. The internal cavity structure can accommodate the cable reel 21 and part of the connecting cable 22, reducing the direct impact of the external environment on the connecting parts; when not in use, it can be closed by the sliding cover 13 to prevent dust and moisture from entering.

[0057] Plate 2 serves as an "integrated carrier" for connection and sealing. Its shape matches the electrical docking slot 12, and it features an annular elastic waterproof ring 30 at its edge. A cable reel 21 is installed on the inner side, with pins 24 at both ends to mate with the mounting positioning holes 16 of the container 1. When two containers 1 are docked, plate 2 is sandwiched between the two electrical docking slots 12, compressing the elastic waterproof ring 30 at its edge to form a sealing barrier, preventing moisture and dust from the processing environment from entering the docking slot and ensuring the cleanliness of the electrical connection (meeting the high cleanliness requirements of tea processing). The thickness of plate 2 is controlled between 2-4mm. Combined with the compressed thickness of the elastic waterproof rings 30 on both sides, the gap between the beams of the docked containers 1 is controlled between 3-5mm. This gap can be filled by installing elastic sealing strips on the inner or outer sides, primarily for waterproofing and relative vibration isolation.

[0058] The quick-release mechanism is a "mechanical locking system" for rapid assembly and disassembly. The structural beam 11 on one side of the cabin 1 contains a transverse groove 25, a sliding locking block 26, a transverse spring 27, and an exposed unlocking lever 28. The plate 2 has a pin 24 with a tenon 241 and an arc-shaped end. During plate 2 installation, the pin 24 is inserted into the mounting positioning hole 16 of the cabin 1. The arc-shaped end of the pin presses against the inclined platform of the sliding locking block 26, forcing the locking block to retract along the transverse groove 25 and compressing the spring. When the pin 24 is fully inserted, the tenon 241 aligns with the locking block, and the spring resets, pushing the locking block into the tenon 241, thus automatically locking the plate 2 to the cabin 1. During disassembly, the exposed unlocking lever 28 is moved laterally, causing the sliding locking block 26 to retract and compress the spring, disengaging the locking block from the tenon 241. The pin 24 can then be pulled out and the plate 2 removed. The mechanical engagement between the sliding lock block 26 and the tenon 241 can resist the vibration of the container 1 during operation, prevent the plate 2 from loosening, and ensure stable power connection.

[0059] The connector 23 and connector 15 are stable conductive connection components. The connector 23 is a cylindrical insulator with multiple sockets integrated, and a threaded cap 231 on the outside. The connector 15 is a pin that matches the socket, and an external threaded sleeve 232 on the outside that matches the cap. The pins and sockets are inserted one-to-one to ensure stable current transmission. The multi-socket / pin design can adapt to circuit requirements with different voltages and currents, such as power and control circuits. After the pins are inserted, the connector and connector are rigidly fixed by the tightening of the threaded cap and the external threaded sleeve 232, avoiding poor contact caused by vibration, which is suitable for the vibration environment of tea processing equipment. The standardized connectors / sockets ensure that the power docking slots 12 of any two compartments 1 can be interchanged, breaking the traditional limitation of "one compartment, one interface" and improving the flexibility of compartment 1 combination.

[0060] The sliding cover 13 serves as a "protective cover" for unused interfaces. It is installed above the opening of the power docking slot 12 and can be pulled up and down along the vertical slide 14. When a power docking slot 12 of a container 1 is not connected to another container 1, the sliding cover 13 is pulled down along the slide to close the opening, preventing dust, debris, and moisture from entering the docking slot, protecting the pins of the wiring socket 15 from corrosion or damage, and ensuring the reliability of the connection during the next use.

[0061] Example 2

[0062] The procedure for using the power connection device between the modular tea primary processing workshop cabins is as follows:

[0063] 1. Planning and Positioning of the 1-unit Modular Container

[0064] Based on the processing requirements of tea, such as the processing flow of different types of green tea (baked green tea, sun-dried green tea), the combination method of modular cabin 1 is determined: Based on the layout path of processing equipment and production lines, as well as the actual site conditions, the number of modular cabins 1 and their specific layout after combination are determined. The number of modular cabins 1 that need to be connected horizontally, the location and number of modular cabins 1 that need to be connected vertically, and whether special local areas require horizontal and vertical combination arrangements are all determined. The positions of parallel connections, front and rear straight-line docking, or horizontal and vertical connections with vertical turning docking, and their positional relationships, are uniformly planned. The number and specifications of the door panels are determined. Each modular cabin 1 has an 1:2 length-to-width ratio, with two electrical connection slots 12 distributed along the long side and one along the wide side. The preset positions of each modular cabin 1 are marked on the installation site to ensure that the electrical connection slots 12 on the docking surfaces of adjacent modular cabins 1 are precisely aligned.

[0065] 2. Equipment component inspection

[0066] Inspection of the first side of the shelter: clean the electrical connection slots 12 on the structural beams 11 that need to be used in each shelter 1, pull up the sliding cover 13, open the electrical connection slots 12, ensure that there are no foreign objects in the slots, check that the pins and external threaded sleeves 232 of the wiring sockets 15 are not bent or corroded, and that the threads of the external threaded sleeves 232 are intact.

[0067] Check whether the mounting positioning holes 16 on both sides of the power connection groove 12 are unobstructed, and whether the sliding lock block 26 and the unlocking lever 28 are flexible. Move the unlocking lever 28 and observe whether the sliding lock block 26 can extend and retract smoothly.

[0068] Confirm that the number of plates 2 is sufficient, and that the elastic waterproof rings 30 on the edges of plates 2 are undamaged and undeformed. Also confirm that the inner side of the pin rod 24 has no bent arc-shaped ends, and that the cable reel 21 rotates freely without jamming. Pull out the connectors 23 at both ends through the cable reel 21, confirming that the connector holes are not blocked and the screw threads are intact. After releasing the tension, confirm that the cable automatically retracts into the reel with a redundancy length of not less than 20cm to compensate for minor positional deviations.

[0069] Check waterproof accessories: Confirm that the waterproof ring 31 at the cable penetration point is not aged and is tightly fitted to the cable sheath.

[0070] 3. Installation and docking phase

[0071] Taking two adjacent modular units, A and B, as an example, the steps are as follows:

[0072] Step 1: Hoist the modular container 1 to the pre-dock position

[0073] Start the hoisting equipment, suspend module B of the shelter, and slowly move it to the preset docking direction of module A of the shelter, which can be horizontal / vertical / horizontal or vertical.

[0074] When the distance between the opposing surfaces of the structural beams 11 of the two container 1 is reduced to about 30cm, the hoisting is suspended to ensure that the central axis of the power docking slots 12 of the two container 1 are aligned. The deviation can be within 5cm because it can be redundantly compensated by the cable reel 21, and the docking surfaces remain relatively parallel.

[0075] Step 2: Preliminary installation of plate 2 and cables

[0076] The operator extends through the work gap and places the plate 2 between the power docking slots 12 of the two containers 1, with the outer side of the plate 2 facing container 1B and the inner side facing container 1A.

[0077] Pull out one end of the connector 23 from the cable reel 21 inside the plate 2, facing the container 1A, and align it with the connector 15 in the power docking slot 12 of the container 1A: align the connector hole with the connector pin, gently insert it, ensuring that the pin is fully inserted into the hole without any misalignment; rotate the threaded cap 231 of the connector clockwise to tighten it with the external threaded sleeve 232 of the connector until it is tight and there is no looseness, and the resistance is uniform.

[0078] Similarly, pull out the other end of the connector 23 from the cable reel 21 on the outside of the plate 2. The cable has already passed through the opening on the plate 2 during production. Pull out the connector 23 towards the container 1B until it connects with the connector 15 in the power docking slot 12 of the container 1B and tighten the cap.

[0079] After confirming that the plugs at both ends are securely connected, gently release the cable and allow it to tighten naturally under the action of the reel.

[0080] Step 3: Fix panel 2 to container 1A

[0081] Adjust the position of plate 2 so that its edge is aligned with the slot of electrical docking groove 12 of container 1A, and align the pin rod 24 on the inner side of plate 2 with the mounting positioning hole 16 on the structural beam 11 of container 1A.

[0082] Push plate 2 forcefully toward container 1A, so that pin 24 is inserted into mounting positioning hole 16:

[0083] The arc-shaped end of the pin 24 contacts the inclined platform of the sliding lock block 26, pressing the lock block to retract along the transverse slide groove 25 and compressing the transverse spring 27.

[0084] When the pin 24 is fully inserted and the end of the pin touches the bottom, the sliding locking block 26 is reset under the action of the spring force and is embedded in the tenon 241 of the pin 24 to achieve automatic locking. You will hear a "click" sound, or you can observe that the unlocking lever 28 has no abnormal displacement.

[0085] Check the fixing effect of plate 2: Gently pull plate 2 to confirm that there is no looseness; observe that the waterproof ring at the edge of plate 2 fits tightly with the edge of the mating groove;

[0086] Step 4: Fitting and Structural Fixing of Container 1B

[0087] Continue to start the hoisting equipment and slowly move the container 1B, reducing the working gap until the structural beams 11 of the two containers 1 are tightly attached. At this time, the edge of the power docking groove 12 of the container 1B presses against the outside of the plate 2, and the waterproof rings on both sides of the plate 2 are compressed, forming a seal of the power docking groove 12.

[0088] Check the initial stability of the power connection: Use power testing instruments to test the circuit inside cabin 1 to confirm that the circuit between the two cabins 1 is conductive and there are no open circuits or short circuits.

[0089] Structural connectors, such as bolts and clips, are installed at corresponding positions on the structural beams 11 of the two modular cabins to ensure that the modular cabins are firmly assembled and do not wobble relative to each other.

[0090] Step 5: Final Inspection

[0091] Ensure that the sliding cover 13 of the unused power docking slot 12 is closed to prevent dust and moisture from entering.

[0092] Example 3

[0093] Based on Example 2, the connection can be expanded to build multiple sets of modular cabin 1 systems.

[0094] Following steps 1-5 of Embodiment 2, dock module C of modular shelter 1 with the already fixed modular shelter 1A or B:

[0095] If it is a horizontal connection (long sides side by side): ensure that the long side docking slot of container 1C is aligned with the long side docking slot of container 1A or B.

[0096] If it is a longitudinal connection (front and rear docking): ensure that the wide side docking slot of container 1C is aligned with the wide side docking slot of container 1A / B.

[0097] If it is a horizontal and vertical connection (vertical turning): Utilize the 11:2 aspect ratio of the container to ensure that the wide side docking slot of container 1C is aligned with the long side docking slot of container 1A / B (precise alignment is achieved through preset slot design).

[0098] After each connection is completed, the overall circuit continuity must be confirmed through the power testing system to avoid local connection failures affecting the overall system.

[0099] After all the modular units 1 are assembled, an overall power test is conducted: the main power supply is connected, and the power supply stability of each modular unit 1 equipment is checked. The voltage and current are normal, and it is confirmed that there are no safety hazards such as leakage or short circuit.

[0100] During the dismantling phase, modular shelter 1 will be reassembled or relocated.

[0101] Step 1: Power off and structural separation

[0102] Disconnect the main power supply to the entire shelter system 1 to ensure that there is no power supply during the dismantling process.

[0103] Remove the structural connecting parts between the modular container 1 to be separated, such as the structural connecting parts between modular container 1B and the adjacent modular container 1A, so that the two modular containers 1 are in a movable state.

[0104] Step 2: Lifting and separating to the work interval

[0105] Start the hoisting equipment and slowly move container 1B to create a working gap of about 30cm between the two containers 1.

[0106] Step 3: Disassemble board 2 and separate it from the cable.

[0107] The operator reaches in from the work gap, moves the unlocking lever 28 on the container 1A, and applies force in the opposite direction to drive the sliding lock block 26 out of the tenon 241 of the pin rod 24. At the same time, the operator gently pulls the plate 2 to pull the pin rod 24 out of the mounting positioning hole 16 and removes the plate 2.

[0108] Rotate the caps of connectors 23 in docking slots 1A and 1B of the container counterclockwise respectively, and pull the connectors out of the connectors 15. Keep the connectors steady when pulling them out to avoid damaging the pins or sockets.

[0109] Retract the plugs at both ends of the connecting cable 22 into the cable reel 21 to ensure that the cable is completely stored without any exposed or tangled parts. Store the plate 2 properly to prevent the waterproof ring from being deformed by pressure.

[0110] Step 4: Completely separate the modular container 1

[0111] Continue to lift and move container 1B until it is completely separated from container 1A, thus completing the dismantling of a single container 1.

[0112] If other modular units 1 need to be dismantled, simply repeat steps 1-4 above.

[0113] Special scenario adaptation: When processing tea with high humidity (such as black tea fermentation), the waterproof seal should be checked daily, and if necessary, sealant should be added to the outside of the waterproof ring to assist in sealing.

[0114] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
