Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to a ship-mounted combined air conditioning outdoor unit and air conditioner. Background Technology

[0002] Ship air conditioning systems are core supporting equipment for ensuring cabin temperature control, equipment operation, and personnel working environment. Among them, the outdoor unit of the air conditioner, as the core host of cooling and heat exchange, plays a key role in heat exchange and system heat dissipation. The outdoor units of the air conditioners equipped on ships mostly adopt an integrated structure, which integrates the compressor, heat exchanger, fan and various pipeline valves into a single frame. It has the characteristics of high structural integration, good overall operation stability, and complete cooling and heat exchange functions, and can meet the cabin temperature control requirements of ships under normal navigation conditions.

[0003] For example, patent CN217004708U discloses an outdoor unit and an air conditioner. The outdoor unit includes a housing, an outdoor heat exchanger, and a water distribution device. The housing has an inner cavity, and a chassis is provided at the lower end of the housing. The chassis is provided with a water collection tank. The outdoor heat exchanger is connected to the housing and located in the inner cavity. The water distribution device is connected to the housing and includes a water pump and a spray pipe. The input end of the water pump is connected to the water collection tank, and the output end of the water pump is connected to the spray pipe. The outlet of the spray pipe faces the outdoor heat exchanger. The water pump of the water distribution device pumps away the water collected on the chassis and then sprays the water onto the outdoor heat exchanger through the spray pipe to help the outdoor heat exchanger dissipate heat. This not only eliminates water accumulation but also accelerates the heat dissipation of the outdoor heat exchanger. Users do not need to connect water pipes to drain the chassis, improving the user experience.

[0004] For example, patent CN218096297U discloses an outdoor unit and an air conditioner. The outdoor unit includes a bracket, a rotating part, and a water-guiding assembly. The bracket is installed inside the outdoor unit and has a driving component. The rotating part includes a mounting part connected to the driving component. The driving component is used to drive the rotation of the mounting part. A guide plate is provided on one axial side of the mounting part, and multiple fan blades are spaced apart on the periphery of the mounting part. The water-guiding assembly is used to guide the condensate from the indoor unit of the air conditioner to the guide plate. The condensate is guided by the guide plate to the fan blades and dispersed by the fan blades. This can reduce the ambient temperature of the outdoor unit, improve the heat exchange efficiency of the outdoor unit, and improve the shutdown problem caused by overload protection due to ambient temperature of the outdoor unit.

[0005] For example, patent CN221705657U discloses an outdoor unit assembly for an air conditioner and an air conditioner. The outdoor unit assembly includes: an outdoor unit, comprising a housing and a computer board disposed within the housing; and a protective box disposed outside the housing, defining an installation space for installing a communication module. One of the housing and the protective box has a wiring hole, and the other has a wiring sleeve. The wiring sleeve is inserted into the wiring hole, and the wiring of the communication module is adapted to connect to the computer board through the wiring sleeve. The wiring sleeve is inserted into the wiring hole, thus connecting the housing and the protective box through the wiring sleeve to achieve wiring.

[0006] However, most ship air conditioning outdoor units are integrated structures, which are large in size and concentrated in weight. The ship deck installation space is small, and the size of the cabin passage and hoisting opening is limited. The integrated air conditioning outdoor unit has a fixed size and cannot be disassembled, making it difficult to complete hoisting, transportation and installation in narrow passages. The assembly and construction are difficult and the work efficiency is low. In addition, once the air conditioning equipment fails, it needs to be completely disassembled for repair, which affects the continuous operation of the ship's air conditioning system and increases the operation cost and labor time consumption of ship equipment assembly and subsequent maintenance.

[0007] To address the aforementioned issues, there is an urgent need for innovative design based on the existing outdoor air conditioning units. Summary of the Invention

[0008] The purpose of this invention is to provide a modular outdoor unit for ship air conditioning, which solves the problems mentioned in the background art. Most ship air conditioning outdoor units are integrated structures with large size and concentrated weight. The installation space on the ship deck is small, and the size of the cabin passage and hoisting opening is limited. The size of the integrated air conditioning outdoor unit is fixed and cannot be disassembled, making it difficult to complete hoisting, transportation and installation in narrow passages. The assembly and construction are difficult and the work efficiency is low. In addition, once the air conditioning equipment fails, it needs to be completely disassembled for repair, which affects the continuous operation of the ship's air conditioning system and increases the operation cost and labor time consumption of ship equipment assembly and subsequent maintenance.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a ship-mounted combined air conditioning outdoor unit, comprising multiple outdoor main units assembled and installed on a ship, with a base correspondingly disposed directly below the outdoor main unit, the base being fixed to the ship surface by bolts, multiple positioning blocks being fixed at equal intervals along the length direction on the upper surface of the base, and two sets of bases being symmetrically fixed on the lower surface of the outdoor main unit, with multiple positioning grooves being equally spaced along the length direction on the lower surface of the base, the base being engaged with the positioning blocks through the positioning grooves, and a locking mechanism for quickly limiting the installation position of the base being provided on the base; the base is also provided with a primary adjustment mechanism for autonomously correcting the hoisting and assembly position of the outdoor main unit to assist the base in moving and docking with the base.

[0010] Preferably, the outdoor unit includes a nacelle fixed to the upper surface of the base. The nacelle houses a compressor, pipe valves, and an electrical box. An air-cooled heat exchanger is installed on the nacelle, and a protective grille is provided on the outer side of the air-cooled heat exchanger. The protective grille is fixedly installed on the nacelle. A condenser fan is installed on the upper end of the air-cooled heat exchanger. A water interface for water connection is installed on the outer side of the nacelle, and an electrical interface for electrical connection is also installed on the outer side of the nacelle.

[0011] Preferably, the locking mechanism includes lateral slides on both sides of the base, and a bottom slide is provided at the bottom of the base. The bottom slide is connected to the two sets of lateral slides, and the end faces of the lateral slides and the bottom slide are in an open state. A stepped slide is provided on the base along the length direction. A protrusion is slidably connected in the stepped slide. A locking rod is fixedly connected to the upper surface of the protrusion. The locking rod is slidably connected to the lateral slide and the bottom slide.

[0012] Preferably, a bidirectional threaded rod is rotatably connected to the base, and an internal threaded post is threaded onto the bidirectional threaded rod, which is fixedly connected to a locking rod; a handle is axially fixed to the end face of the bidirectional threaded rod.

[0013] Preferably, the primary adjustment mechanism includes a hollow column fixed to the upper surface of the base, a telescopic bracket telescopically connected in the hollow column, and multiple trigger rods fixed at equal intervals laterally on the telescopic bracket; the multiple trigger rods are distributed at intervals with multiple positioning blocks, and the side of the trigger rod closest to the positioning block is arc-shaped.

[0014] Preferably, a return spring is elastically connected between the telescopic bracket and the hollow column.

[0015] Preferably, the base is provided with a secondary adjustment mechanism for further correcting the installation position of the outdoor unit, and the correction direction of the secondary adjustment mechanism is perpendicular to the correction direction of the primary adjustment mechanism.

[0016] Preferably, the secondary adjustment mechanism includes a primary slide rail and a secondary slide rail formed on the base. A corrective support rod is slidably connected through the primary slide rail, and the corrective support rod is correspondingly arranged on the outer side of the base end face. A transmission support rod is slidably connected through the secondary slide rail, and an embedded slide bar is fixedly connected between the transmission support rod and the corrective support rod. The embedded slide bar is slidably installed inside the base.

[0017] Preferably, the hollow column is provided with a transverse sliding groove, and a transverse sliding rod is slidably connected in the transverse sliding groove. The transverse sliding rod is connected to the telescopic bracket. A push rod is rotatably connected to the transmission support rod, and the other end of the push rod is rotatably connected to the transverse sliding rod. The push rod is inclinedly connected between the transmission support rod and the transverse sliding rod.

[0018] An air conditioner, comprising the aforementioned ship-mounted combined air conditioner outdoor unit.

[0019] Compared with the prior art, the beneficial effects of the present invention are: This invention adopts a modular assembly structure with multiple independent outdoor main units, breaking down the traditional large-volume integrated outdoor unit into multiple small, standardized main unit units. Each outdoor main unit can be independently installed on a base on the ship's deck. Compared with the integrated equipment, each main unit is smaller and lighter, greatly reducing the difficulty of hoisting, transporting, and positioning in the ship's narrow hatches and limited deck space. When a single outdoor main unit fails or its performance deteriorates, the faulty module can be disassembled, repaired, or replaced individually without shutting down the entire system. The remaining main unit modules can continue to operate normally, effectively ensuring the continuous and stable operation of the ship's air conditioning system and improving the maintainability and combat readiness reliability of the ship's air conditioning equipment.

[0020] The base is equipped with a locking mechanism that quickly limits the installation position of the base. During assembly, the positioning groove at the bottom of the base and the positioning block on the base quickly engage, which can complete the initial alignment and limiting of the outdoor unit and achieve rapid pre-installation. On this basis, through the thread transmission cooperation between the bidirectional threaded rod and the internal threaded column, the locking rod can be driven to slide precisely along the side slide and the bottom slide, further limiting the installation position of the base from the side and bottom, realizing the secondary locking and fixing of the outdoor unit and maintaining the stability of the outdoor unit after assembly.

[0021] The base is also equipped with a primary adjustment mechanism that can autonomously correct the position of the outdoor unit during hoisting and assembly. During the hoisting and lowering of the outdoor unit and the docking of the base with the base, the lower edge of the base presses against the arc end face of the trigger rod, automatically pushing the trigger rod to make the trigger rod move laterally adaptively. This allows multiple sets of trigger rods to fit against the outer wall of the base, constraining and correcting the lateral installation position of the two sets of bases. It automatically corrects the deviations generated during hoisting, ensuring that the base positioning groove and the base positioning block can be accurately aligned, reducing the difficulty of manual alignment and calibration, and improving assembly efficiency.

[0022] The base is equipped with a secondary adjustment mechanism for further correcting the installation position of the outdoor unit. The correction direction of the secondary adjustment mechanism is perpendicular to that of the primary adjustment mechanism, forming a two-way orthogonal three-dimensional correction system. While the primary adjustment mechanism completes the lateral position correction, it can simultaneously link the push rod, transmission support rod and embedded sliding strip transmission structure to achieve the clamping correction of the longitudinal position of the base end. This further corrects the installation deviation of the base from the vertical direction, achieving precise coaxial docking of the positioning slot and the positioning block. Through the two-way coordinated adjustment of the primary and secondary mechanisms, the fully automatic and high-precision three-dimensional correction of the outdoor unit hoisting and docking is achieved, improving the assembly accuracy and efficiency of multi-module combined air conditioning outdoor units, and adapting to the application scenarios of rapid assembly and rapid replacement of damaged pipes on ships.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a ship-mounted combined air conditioning outdoor unit, comprising multiple sets of outdoor main units 1 assembled and installed on a ship, a base 3 correspondingly provided directly below the outdoor main unit 1, the base 3 being fixed to the surface of the ship by bolts, a plurality of positioning blocks 5 being fixed at equal intervals along the length direction on the upper surface of the base 3, two sets of bases 2 being symmetrically fixed on the lower surface of the outdoor main unit 1, a plurality of positioning grooves 4 being provided at equal intervals along the length direction on the lower surface of the base 2, the base 2 being engaged with the positioning blocks 5 through the positioning grooves 4, and a locking mechanism for quickly limiting the installation position of the base 2 being provided on the base 3; the base 3 is also provided with a primary adjustment mechanism for autonomously correcting the hoisting and assembly position of the outdoor main unit 1, to assist the base 2 in moving and docking with the base 3.

[0038] Before assembly, marine-grade anti-corrosion bolts are used to penetrate the pre-drilled mounting holes around the base 3, rigidly locking the entire base 3 to the ship's open deck or mezzanine platform, ensuring that the base 3 is level and without tilt. Multiple positioning blocks 5 are pre-welded and fixed to the upper surface of the base 3 at equal intervals during manufacturing. The positioning blocks 5 have a trapezoidal structure, narrower at the top and wider at the bottom. When hoisting a single outdoor unit 1, the outdoor unit 1 is smoothly lowered using a small shipboard lifting device. The two sets of bases 2 at the bottom of the outdoor unit 1 move downwards synchronously, aligning the positioning grooves 4 on the bottom surface of the base 2 with the positioning blocks 5 on the surface of the base 3. The contour matching of groove 4 and positioning block 5 achieves preliminary engagement and positioning, completing the initial alignment of outdoor unit 1. If base 2 shifts left or right during hoisting, the first-level adjustment mechanism on base 3 will simultaneously contact the side wall of base 2, automatically pushing base 2 to return to the center laterally, assisting positioning groove 4 in accurately engaging positioning block 5. After preliminary positioning is completed, the operator can activate the matching locking mechanism of base 3 to clamp base 2 from the side and bottom, completing the locking and fixing of a single outdoor unit 1. Multiple outdoor units 1 can be hoisted and engaged sequentially along the length of base 3, all independently assembled, with no interference between individual unit disassembly and assembly.

[0039] Please see Figure 1 - Figure 3 The outdoor unit 1 includes a nacelle 101 fixed to the upper surface of the base 2. The nacelle 101 houses the compressor, pipeline valves and electrical box. An air-cooled heat exchanger 102 is installed on the nacelle 101. A protective grille 103 is provided on the outer side of the air-cooled heat exchanger 102. The protective grille 103 is fixedly installed on the nacelle 101. A condenser fan 104 is installed on the upper end of the air-cooled heat exchanger 102. A water interface 105 for water connection is installed on the outer side of the nacelle 101. An electrical interface 106 for electrical connection is also installed on the outer side of the nacelle 101.

[0040] The engine room 101 is constructed entirely of 316 stainless steel anti-corrosion sheet metal welded together. Its bottom is bolted to the upper surface of the base 2, forming an integrated load-bearing unit. The engine room 101 has a sealed, partitioned interior. One compartment houses the marine scroll compressor, liquid receiver, dryer filter, four-way reversing valve, and other piping and valves. The other side has an independent isolation compartment housing the electrical control box, separating the refrigerant piping from electrical components to prevent leakage and short circuit risks in the high-humidity, salt-spray environment of the ship. The upper frame of the engine room 101 is fitted with an air-cooled heat exchanger 102, surrounded by a protective grid 103. This grid blocks deck debris and wave impacts on the fins without obstructing airflow. The air-cooled heat exchanger 102 is secured with a top flange. The condenser fan 104 exhausts air upwards to achieve forced air cooling. Two sets of standardized interfaces are integrated on the outer wall of the same side of the nacelle 101. The lower one is the water interface 105. The water interfaces 105 of multiple outdoor units 1 are connected in parallel to the fan coil units inside the nacelle through corrugated pipes and water distribution collectors. The upper one is the circuit interface 106. The circuit interface 106 is equipped with a waterproof cover for outdoor use. The communication lines and power lines of each outdoor unit 1 are uniformly connected to the centralized control cabinet to realize multi-module linkage control and individual fault reporting. When a single outdoor unit 1 is to be repaired in the future, it can be disassembled independently by simply unplugging the corresponding outdoor unit 1's water interface 105 and circuit interface 106 without disconnecting the entire system's piping and power supply.

[0041] Please see Figure 3 - Figure 8 The locking mechanism includes side slides 21 on both sides of the base 2, and a bottom slide 22 at the bottom of the base 2. The bottom slide 22 is connected to the two sets of side slides 21, and the end faces of the side slides 21 and the bottom slide 22 are in an open state. A stepped slide 31 is provided on the base 3 along the length direction. A protrusion 32 is slidably connected in the stepped slide 31. A locking rod 23 is fixedly connected to the upper surface of the protrusion 32. The locking rod 23 is slidably connected to the side slides 21 and the bottom slide 22.

[0042] The base 2 has through-type side slides 21 on both sides along its length, and a bottom slide 22 on the lower side of the base 2. The internal channels of the three are interconnected, and both ends of the slides are completely open to facilitate the unobstructed insertion and sliding of the locking rod 23. A long stepped slide 31 is opened parallel to the top surface of the base 3. A protrusion 32 is installed inside the stepped slide 31. The protrusion 32 can be moved laterally along the entire stepped slide 31. The locking rod 23 is vertically welded to the upper surface of the protrusion 32. The cross-sectional dimensions of the locking rod 23 are precisely matched with the internal gaps of the side slides 21 and the bottom slide 22. When the outdoor unit 1 is lowered, the base 2 and the positioning block 5 engage. Once in position, control the locking rod 23 and the protrusion 32 to move laterally. The locking rod 23 slides into the open side slide 21 and bottom slide 22 ports on the outside of the base 2. The locking rod 23 moves and locks itself in the base 2, restricting the base 2 from lateral displacement and upward tilting. The stepped slide 31 provides vertical support for the protrusion 32, bearing the shear force caused by navigation vibration and hull tilting, preventing the locking rod 23 from deforming and falling out of the slide, ensuring that the base 2 does not loosen during long-term navigation. When the equipment is inspected and disassembled, reverse drive the locking rod 23 to slide out of the side slide 21 and bottom slide 22, and the outdoor main unit 1 can be lifted directly.

[0043] Please see Figure 4 - Figure 7 A bidirectional threaded rod 6 is rotatably connected to the base 3. An internal threaded post 7 is threaded onto the bidirectional threaded rod 6. The internal threaded post 7 is fixedly connected to the locking rod 23. A handle 8 is axially fixed to the end face of the bidirectional threaded rod 6.

[0044] Bearing seats are installed at both ends of the base 3. The two-way threaded rod 6 is rotatably supported inside the bearing seats at both ends. The two sections of the two-way threaded rod 6 are provided with external threads with opposite directions. Each of the two threaded sections is equipped with a set of internal threaded posts 7. Each internal threaded post 7 is fixedly connected to a locking rod 23 on its side. When the operator rotates the handle 8, the two-way threaded rod 6 rotates synchronously. The two sets of internal threaded posts 7 are driven by the opposite threads and move synchronously towards the middle position of the base 3. This causes the locking rods 23 on both sides to be inserted into the side slide 21 and bottom slide 22 of the base 2 at the same time, clamping the base 2 in both directions to achieve quick locking. When disassembling, the handle 8 is rotated in the opposite direction. The two internal threaded posts 7 slide separately towards both ends of the base 3. The locking rods 23 are simultaneously completely withdrawn from the side slide 21 and bottom slide 22, releasing the locking state of the base 2 and making it easy to remove it from the base 3.

[0045] Example 2: Please refer to Figure 2 - Figure 10Based on Embodiment 1, a primary adjustment mechanism and a secondary adjustment mechanism are also disclosed for adjusting the installation and docking position of the outdoor unit of the air conditioner. The specific structure is as follows: The primary adjustment mechanism includes a hollow column 9 fixed on the upper surface of the base 3. A telescopic bracket 10 is telescopically connected in the hollow column 9. Multiple trigger rods 11 are fixed horizontally at equal intervals on the telescopic bracket 10. The multiple trigger rods 11 are distributed at intervals with multiple positioning blocks 5, and the side of the trigger rod 11 close to the positioning block 5 is arc-shaped.

[0046] Hollow column 9 is welded and fixed to the upper surface of base 3. Hollow column 9 is hollow inside. Telescopic bracket 10 is inserted horizontally into hollow column 9 to achieve telescopic sliding. During the process of hoisting outdoor unit 1 and lowering it down, if base 2 shifts left and right, the lower edge of base 2 will contact the arc end face of trigger rod 11 in advance. The force of continuous downward pressure of base 2 will be decomposed into lateral thrust along the arc surface, pushing telescopic bracket 10 and trigger rod 11 to slide to both sides. Multiple trigger rods 11 on both sides simultaneously fit and press against the left and right outer walls of base 2 (when the positioning groove 4 corresponds to the positioning block 5, the trigger rod 11 moves to the deepest position inside hollow column 9 and can no longer move inward, thus achieving the pressing effect on the outside of base 2). The shifted base 2 is automatically corrected to the center of base 3, so that the positioning groove 4 on the bottom surface of base 2 is accurately aligned with positioning block 5. After base 2 is completely lowered and locked on positioning block 5, the amount of manual alignment and calibration work is reduced.

[0047] Please see Figure 10 and Figure 11 A return spring 12 is elastically connected between the telescopic bracket 10 and the hollow column 9.

[0048] The return spring 12 is sleeved inside the telescopic bracket 10. Under normal conditions, the return spring 12 continuously pushes the telescopic bracket 10, so that the trigger rod 11 is located below the base 2. When the outdoor unit 1 is hoisted down and squeezes the trigger rod 11, the telescopic bracket 10 overcomes the elastic force of the return spring 12 and contracts inward. The return spring 12 stores elastic potential energy. After the faulty outdoor unit 1 is disassembled and hoisted and the base 2 is completely separated from the base 3, the return spring 12 releases its elastic force and automatically lifts the telescopic bracket 10 and the trigger rod 11, restoring the initial correction position. No manual reset is required, and subsequent hoisting and alignment operations of the outdoor unit 1 can be carried out directly to achieve continuous assembly. The return spring 12 is made of marine stainless steel corrosion-resistant compression spring, which is suitable for high salt spray and high and low temperature marine working conditions and is not easy to rust and fail after long-term use.

[0049] Please see Figure 2 - Figure 12 The base 3 is provided with a secondary adjustment mechanism for further adjusting the installation position of the outdoor unit 1. The adjustment direction of the secondary adjustment mechanism is perpendicular to the adjustment direction of the primary adjustment mechanism.

[0050] The primary adjustment mechanism achieves lateral correction of the base 2, while the secondary adjustment mechanism is arranged along the length of the base 3 and is responsible for the front-back correction of the base 2. The two correction directions are perpendicular to each other, forming an orthogonal two-way three-dimensional correction system. While the base 2 is laterally centered by the primary adjustment mechanism, the front and rear ends of the base 2 will contact the correction support rod 16 of the secondary adjustment mechanism. The front-back position correction of the base 2 is completed synchronously by mechanical linkage. The two-way synchronous correction corrects the front-back and left-back offsets caused by hoisting, ensuring that the multiple positioning slots 4 of the base 2 can simultaneously and completely engage all the positioning blocks 5 on the base 3, avoiding local slot misalignment and incomplete engagement, and improving the overall accuracy of multi-module assembly.

[0051] Please see Figure 2 and Figure 12 The secondary adjustment mechanism includes a primary slide rail 15 and a secondary slide rail 17 on the base 3. A straightening support rod 16 is slidably connected through the primary slide rail 15 and is correspondingly arranged on the outer side of the end face of the base 2. A transmission support rod 18 is slidably connected through the secondary slide rail 17. An embedded slide bar 19 is fixedly connected between the transmission support rod 18 and the straightening support rod 16 and is slidably installed inside the base 3.

[0052] A correction support rod 16 is installed inside the first-stage slide rail 15. The end of the correction support rod 16 extends out of the upper surface of the base 3 and faces the front and rear end faces of the base 2. The correction support rod 16 and the locking rod 23 are staggered to avoid motion interference. The transmission support rod 18 is installed inside the second-stage slide rail 17. The transmission support rod 18 and the correction support rod 16 are rigidly welded together by an embedded slide bar 19. The embedded slide bar 19 is completely housed in the internal slide cavity of the base 3 and only slides in a straight line without any exposed jamming parts. When the base 2 presses down on the trigger rod 11 of the first-stage adjustment mechanism, causing it to move laterally, the front and rear end faces of the base 2 push the correction support rod 16 to slide along the first-stage slide rail 15. The correction support rod 16 drives the transmission support rod 18 to move synchronously along the second-stage slide rail 17 through the embedded slide bar 19. Based on the simultaneous inward clamping of the front and rear ends of the base 2 by the correction support rods 16 on both sides, the back and forth movement of the base 2 is restricted, and the precise correction of the installation position is completed.

[0053] Please see Figure 12 A transverse sliding groove 13 is provided on the hollow column 9, and a transverse sliding rod 14 is slidably connected in the transverse sliding groove 13. The transverse sliding rod 14 is connected to the telescopic bracket 10. A push rod 20 is rotatably connected to the transmission support rod 18. The other end of the push rod 20 is rotatably connected to the transverse sliding rod 14. The push rod 20 is inclinedly connected between the transmission support rod 18 and the transverse sliding rod 14.

[0054] During the hoisting and lowering process, the base 2 presses down the trigger rod 11, which drives the telescopic bracket 10 and the transverse slide rod 14 to move downward. The transverse slide rod 14 pulls the tilting push rod 20 to swing. When the push rod 20 rotates, it drives the transmission support rod 18 to slide inward along the secondary slide rail 17, which simultaneously drives the two side correction support rods 16 to clamp the end face of the base 2. This realizes the mechanical linkage between the first-level adjustment action and the second-level adjustment action. The bidirectional correction can be completed synchronously by relying solely on the self-weight of the outdoor main unit 1. No additional manpower is required for adjustment, which simplifies the assembly process on the ship. When the main unit is disassembled, the transmission support rod 18 and the correction support rod 16 automatically release the base 2, without affecting the hoisting and removal of the outdoor main unit 1.

[0055] Example 3: An air conditioner, including the aforementioned ship-mounted combined air conditioner outdoor unit. The combined air conditioner outdoor unit mainly includes an outdoor main unit 1, a base 2, a base 3, an indoor fan coil unit, a centralized electrical control cabinet, a circulating water system, and a communication harness. During the assembly stage, the base 3 is first fixed in batches to designated areas on the ship's deck. Single small outdoor main units 1 are then lowered sequentially using hoisting equipment. The alignment is automatically corrected by a primary and secondary adjustment mechanism, ensuring that the positioning slot 4 and positioning block 5 are precisely engaged. The handle 8 is then rotated to move and lock the locking rod 23. Multiple outdoor main units 1 have water interface 105s connected in parallel to the cold water circulation pipeline via anti-corrosion corrugated pipes. The electrical interface 106 is uniformly connected to the centralized control cabinet. The control cabinet automatically adjusts the load according to the cabin load. The system dynamically allocates the number of operating main units, activating only some modules under low load for energy-saving operation. During routine maintenance, if any outdoor main unit 1 experiences compressor failure or heat exchanger blockage, the water interface 105 and electrical interface 106 of that unit can be disconnected individually, and the locking mechanism can be released by rotating the handle 8 in the opposite direction. The faulty outdoor main unit 1 can then be lifted and replaced directly, while the remaining outdoor main units 1 continue to operate normally, ensuring uninterrupted cooling of the ship's cabins. Compared to traditional integrated large outdoor units, this solution features smaller and lighter outdoor main units 1, which can be transported through narrow hatches and mezzanine passages on ships. It is suitable for the fragmented and irregularly shaped deck spaces of ships, reducing the assembly time of ship equipment and the difficulty of subsequent damage control and maintenance, thus meeting the needs of ships for long-term deployment and rapid repair.
