Description

Technical Field

[0001] This invention belongs to the technical field of marine air conditioning systems, and specifically relates to a high-efficiency air distributor for foldable and installable cabins in cruise ships. Background Technology

[0002] With the rapid development of the cruise industry, modular construction technology has become the mainstream trend in cruise ship construction. Among them, push-back cabins are widely used in large cruise ships because they can be flexibly installed and repositioned after the hull assembly, significantly improving the space utilization and production efficiency of shipyards.

[0003] In the air conditioning and ventilation system of a push-alley cabin, the air distributor, as the terminal device for air distribution, directly affects cabin comfort and the energy efficiency of the air conditioning system due to its installation quality. In existing technology, cruise ship cabins generally use fixed air distributors, which are typically installed in the ceiling via rigid brackets and must be flush with the ceiling finish after installation. However, the construction process for push-alley cabins is unique: after the main structure is completed in the workshop, the cabin needs to be moved as a whole to its predetermined position on the hull. During this process, the ceiling and internal piping and wiring usually need to be reserved or temporarily withheld to avoid interference during movement. After the cabin is moved into place, workers enter the cabin and install the ceiling, air distributor, and other components in sequence.

[0004] Therefore, how to provide a high-efficiency, foldable air diffuser for cruise ship cabins that can improve cabin installation efficiency, reduce overall construction costs, and enhance the flexibility of modular cruise ship design has become an urgent technical problem to be solved.

[0017] Figure 1 This is a schematic diagram of a foldable, high-efficiency air distributor for use in a cruise ship's pushable cabin, according to an embodiment of the present invention. In the diagram, 1 is the air duct, 2 is the terminal static pressure box, 3 is the ceiling, 4 is the guide rail bracket, 5 is the diffuser, and 6 is the angle steel bracket. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] In this embodiment of the invention, a high-efficiency, foldable air diffuser for use in a cruise ship's push-back cabin includes: The main body is a flexible fabric that has a folded state and an unfolded state. A support frame, connected to the flexible fabric body, is used to support and maintain the flexible fabric body in the unfolded state to form an air outlet surface; Fixed connectors are used to install the support frame or the flexible fabric body to the reserved installation points on the cabin ceiling; An extension device, connected to the support frame, is used to drive the support frame to switch from the folded state to the unfolded state; The support frame is a hinged frame with multiple rotating joints or a telescopic frame with multiple sliding joints; in the folded state, the overall height of the air distributor is not greater than the minimum vertical distance between the cabin ceiling and the highest obstacle in the pushing path of the pushable cabin.

[0020] In this invention, a foldable, high-efficiency air diffuser for use in cruise ship push-away cabins is described. Through a "flexible fabric body + switchable support frame," the overall height of the air diffuser is dynamically adjusted, allowing it to retract to a height not exceeding the minimum clearance during cabin push-away, completely avoiding interference with any obstacles in the cabin's movement path. An "extension device" is introduced to actively drive the unfolding, eliminating the need for manual climbing into the ceiling for operation, significantly improving installation convenience. This invention fundamentally eliminates the step of "removing and reassembling the ceiling after push-away to install the air diffuser" found in traditional solutions, reducing installation time by approximately 50% or more.

[0021] In another embodiment of the present invention, the support frame includes: The fixed frame is rigidly connected to the ceiling via the fixed connector; At least one movable frame part is connected to the fixed frame part via the rotary joint or sliding joint; In the folded state, the movable frame portion is folded under or to the side of the fixed frame portion; in the unfolded state, the movable frame portion is unfolded and locked relative to the fixed frame portion, so that the flexible fabric body is stretched to form the air outlet surface.

[0022] The support frame is specifically divided into a fixed frame section and a movable frame section, clarifying the mechanical implementation method of "folding and unfolding". This hinged or telescopic structure is simple, reliable, and low in cost, and can ensure that the flexible fabric body is reliably tensioned after each unfolding, avoiding uneven airflow caused by wrinkles.

[0023] In another embodiment of the present invention, the air distributor further includes: a reserved groove provided on the ceiling; The opening of the reserved slot faces the interior of the cabin, and the interior space of the reserved slot accommodates the flexible fabric body and at least part of the support frame in the folded state; The reserved slot is provided with a guide rail and at least one locking position. The fixed connector can be slidably fitted with the guide rail and can be selectively locked in the locking position.

[0024] The combination of a "pre-reserved slot" and a "guide rail + locking position" allows the air distributor to be completely embedded in the ceiling when folded, without affecting the cabin's height, and is protected from external impacts during movement. The guide rail structure allows for minor positional adjustments to the air distributor after unfolding to compensate for cabin manufacturing errors and ensure precise alignment with the ceiling opening.

[0025] In another embodiment of the present invention, the depth of the reserved groove is not less than the overall height of the air distributor in the folded state, and a sealing strip is provided at the opening edge of the reserved groove; in the unfolded state, the edge of the flexible fabric body fits against the sealing strip to form an airtight connection.

[0026] In another embodiment of the present invention, the flexible fabric body is provided with a plurality of micropores, the pore diameter, spacing or opening density of the micropores being adjustable to form an air distribution structure with variable flow resistance.

[0027] In another embodiment of the present invention, the stretching device is an electric stretching device, comprising a micro motor, a transmission mechanism and a control switch; The micro motor drives the support frame to unfold via the transmission mechanism; the control switch is located on the cabin wall or integrated into the cabin control system for remote or local control of the start and stop of the extension device.

[0028] In another embodiment of the present invention, the flexible fabric body is made of a flexible composite material with a flame retardant rating of not less than B1, and the flexible fabric body includes an inner fabric, an intermediate insulation layer and an outer fabric, wherein the intermediate insulation layer is sandwiched between the inner fabric and the outer fabric.

[0029] Among them, flame-retardant materials of no less than B1 grade are used to meet the ship fire protection specifications; the composite structure of inner layer, insulation layer and outer layer has the functions of heat preservation and anti-condensation, which prevents condensation from dripping onto the outer surface of the flexible fabric when the air conditioner is blowing air, thus improving the comfort of riding.

[0030] In another embodiment of the present invention, a limiting structure is provided on a plurality of rotating or sliding joints of the support frame, the limiting structure being used to limit the maximum unfolding angle or maximum unfolding stroke of the movable frame portion relative to the fixed frame portion in the unfolded state.

[0031] In another embodiment of the present invention, the air distributor further includes an end static pressure box; The air inlet of the terminal static pressure box is connected to the air conditioning duct, and the air outlet of the terminal static pressure box is connected to the internal space of the flexible fabric body through a flexible duct or directly; the fixed connector installs the terminal static pressure box to the ceiling, and the support frame is connected to the bottom of the terminal static pressure box.

[0032] In another embodiment of the present invention, a method for installing an air conditioning system for a cruise ship's push-back cabin is provided, based on a foldable, high-efficiency air distributor for push-back cabins of cruise ships as described in any of the above claims, the method comprising: Pre-installation steps: During the cabin manufacturing stage, the air distributor in the folded state is pre-installed into the reserved groove in the ceiling, and the air distributor is kept in the folded state by temporary fasteners. Pushing step: With the air distributor in a folded state and not protruding from the ceiling surface, push the pushable compartment to the target installation position on the hull; Preparation steps: Release the temporary fastener and operate the extension device to make the support frame drive the flexible fabric body to descend downward or unfold to the side from the reserved groove; Locking step: When the support frame moves to the end position of the limiting structure, the flexible fabric body is fully tensioned to form an air outlet surface, and the fixed connector slides along the guide rail in the reserved groove to the preset locking position and locks. Sealing connection step: The edge of the flexible fabric body is fitted with the sealing strip at the edge of the reserved groove opening to form an airtight connection; Debugging steps: Connect the air conditioning system, adjust the microporous air outlet structure on the flexible fabric body, and test the uniformity of air distribution and air tightness.

[0033] In this embodiment of the invention, an air conditioning system installation method for a push-back cabin on a cruise ship organically links six steps—pre-installation, pushing, unfolding, locking, sealing, and debugging—to form a complete air conditioning terminal installation process specifically for push-back cabins. The "unfolding preparation" and "locking" steps fully utilize limiting and guide rail structures, achieving highly efficient operation of "unfolding equals positioning, positioning equals locking," avoiding the tedious process of repeated measurement and adjustment in traditional methods. This method and the device claims mutually support each other, forming comprehensive protection from product to process.

[0034] like Figure 1 As shown, Figure 1 This is a schematic diagram of a high-efficiency, foldable air distributor for use in a cruise ship's push-back cabin, according to an embodiment of the present invention.

[0035] Figure 1 Among them, a foldable, high-efficiency air distributor for use in cruise ship push-back cabins includes: a terminal plenum box 2, which is flat and made of galvanized steel sheet, with an air inlet at the top, which is connected to the main air conditioning duct 1 via a flexible hose. The two sides of the terminal plenum box 2 are mounted to the ceiling joists 3 via angle steel brackets 6 and fixing connectors. The bottom of the terminal plenum box 2 has a circular or rectangular air outlet.

[0036] The support frame adopts a hinged structure, including one fixed frame section and two movable frame sections. The fixed frame section is bolted to the bottom edge of the end static pressure box 2. The movable frame sections are connected to opposite sides of the fixed frame section via hinges as rotating pairs. Each hinge is equipped with a limiting structure, restricting the maximum outward opening angle of the movable frame section to 90°, meaning that after opening, the movable frame section and the fixed frame section are on the same horizontal plane. Each movable frame section is also equipped with a spring-loaded preload mechanism.

[0037] The flexible fabric body is made of three layers of composite material: an inner layer of flame-retardant polyester mesh fabric, a middle layer of flame-retardant polyethylene foam, and an outer layer of flame-retardant Oxford cloth. The entire flexible fabric body achieves a flame-retardant rating of B1. The fabric body is cut to a shape corresponding to the supporting frame, and its edges are connected to the various frame sections of the supporting frame by sewing or heat sealing. On the side of the fabric body facing the cabin interior, micropores are formed according to a preset hole spacing (e.g., 50mm) and hole diameter (e.g., 3mm). To facilitate adjustment of airflow characteristics, a detachable fabric module is provided in the central area of ​​the fabric body. This module is connected to the body via a zipper, and micropores of different diameters or densities can be replaced on the module.

[0038] The extension device is a manually operated mechanism, specifically a pull rope connected to the movable frame. The operator pulls the rope to rotate and extend the movable frame around a hinge. In another variant, the extension device is an electrically operated actuator, comprising a miniature DC motor, a worm gear reducer, and a push rod. The motor is fixed to the side of the end hydrostatic chamber, and the end of the push rod is connected to the movable frame. A switch on the cabin wall controls the motor's forward or reverse rotation, achieving electric extension and retraction.

[0039] A rectangular recess, 80mm deep, is provided in the ceiling 3. In the folded state, the entire air distributor is completely contained within this recess. The overall height of the folded air distributor is 75mm, less than the depth of the recess, thus preventing it from protruding from the ceiling surface. Two parallel guide rails 4 are provided on the inner wall of the recess, allowing the fixing connectors on both sides of the end static pressure box to slide along these rails. Two locking positions are provided on the guide rails: one for the folded storage position and one for the unfolded working position. Each locking position is equipped with a spring-loaded locking pin.

[0040] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
