Description

Technical Field

[0001] This utility model relates to the field of marine air supply technology, specifically a multi-section tubular universal air supply mechanism. Background Technology

[0002] In ship transport, cargo in the hold (such as perishable goods and food products that are sensitive to temperature) requires a stable, cool air environment to maintain freshness. Traditional ship cabin air supply systems typically use fixed-direction air outlets, delivering cool air along a fixed path, making it difficult to dynamically adjust the airflow direction based on the cargo's stacking location. If the air outlets cannot be directly aimed at the cargo, it can easily lead to uneven local temperatures, affecting the preservation effect. In addition, the compact space in ship cabins and the limited layout of air supply ducts mean that traditional fixed air outlets lack the flexibility to be adjusted, failing to meet the diverse storage needs of cargo. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-segment tubular universal air supply mechanism. Through the design of multiple rotatable inclined pipe segments, the orientation of the air supply outlet can be precisely adjusted so that the cold air is blown directionally to the cargo in the compartment, thereby improving the uniformity and efficiency of preservation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-segment duct-type universal air supply mechanism includes an air supply duct segment and a flange installed at the upper end of the air supply duct segment; it also includes multiple sets of continuously rotatable deflector duct segments installed below the air supply duct segment and coaxially arranged with the air supply duct segment, and multiple sets of drive components respectively installed on the side wall of the air supply duct segment and the side wall of the deflector duct segment and driving each deflector duct segment to rotate independently; all deflector duct segments are inclined pipes, and each set of inclined pipes has at least one inclined surface.

[0005] By adopting the above solution, the universal air supply mechanism is designed with multiple independently rotatable deflector pipe sections. Since the deflector pipe sections are beveled pipes, the direction of the air supply outlet can be adjusted in multiple dimensions. It can be used in the cold storage compartments of ships. The direction of the cold air can be dynamically adjusted according to the stacking position of the cargo in the compartment to ensure that the cold air directly covers the cargo and improves the uniformity of preservation.

[0006] As a preferred embodiment of a multi-segment duct-type universal air supply mechanism, three sets of reversing pipe segments are provided, which are reversing pipe segment one, reversing pipe segment two, and reversing pipe segment three from top to bottom; three sets of drive components are provided, which are drive component one, drive component two, and drive component three from top to bottom; by driving the three sets of drive components to drive the three sets of reversing pipe segments to rotate independently, multi-dimensional adjustment of the air outlet orientation can be achieved, thereby improving the flexibility of air supply.

[0007] In a preferred embodiment of a multi-segment omnidirectional air supply mechanism, the drive assembly includes a base fixed to the side wall of the air supply duct segment, a motor fixed to the base, a drive gear concentrically connected to the motor shaft, and a driven gear ring fixedly connected to the upper edge of the deflecting duct segment. The motor drives the deflecting duct segment to rotate around the axis of the air supply duct segment through the meshing of the drive gear and the driven gear ring. The upper surface of the deflecting duct segment is a plane concentrically fitted with the lower surface of the air supply duct segment, and the lower surface of the deflecting duct segment is an inclined plane. By rotating the deflecting duct segment, the angle of the inclined plane on its lower surface changes, which can initially adjust the downward flow direction of the cold air.

[0008] In a preferred embodiment of a multi-segment omnidirectional air supply mechanism, the drive assembly two includes a base two fixed to one side wall of the deflecting pipe segment, a motor two fixed to the base two, a drive gear two concentrically connected to the shaft of the motor two, and a driven gear ring two fixedly connected to the upper edge of the deflecting pipe segment two. The motor two drives the deflecting pipe segment two to rotate around the axis of the air supply pipe segment through the meshing of the drive gear two and the driven gear ring two. The upper surface of the deflecting pipe segment two is an inclined surface concentrically fitted with the lower surface of the deflecting pipe segment, and the lower surface of the deflecting pipe segment two is also an inclined surface. The double inclined surface design of the deflecting pipe segment two can further expand the airflow adjustment range and make the cold air flow direction more precise.

[0009] In a preferred embodiment of a multi-segment omnidirectional air supply mechanism, the drive assembly three includes a base three fixed to the side wall of the deflecting pipe segment two, a motor three fixed to the base three, a drive gear three concentrically connected to the shaft of the motor three, and a driven gear ring three fixedly connected to the upper edge of the deflecting pipe segment three. The motor three drives the deflecting pipe segment three to rotate around the axis of the air supply pipe segment through the meshing of the drive gear three and the driven gear ring three. The upper surface of the deflecting pipe segment three is an inclined surface concentrically fitted with the lower surface of the deflecting pipe segment two, and the lower surface of the deflecting pipe segment three is a plane. The outlet of its lower surface is the final air outlet, and the final air supply direction is adjusted by the rotation of the deflecting pipe segment three.

[0010] As a preferred embodiment of a multi-segment omnidirectional air supply mechanism, the lower air outlet of the deflecting pipe segment three is an inwardly contracting opening; the contracting design can accelerate the airflow velocity of the cold air, so that the cold air is concentrated and blown towards the goods, thereby improving the local cooling efficiency.

[0011] As a preferred embodiment of a multi-section duct-type universal air supply mechanism, a filter screen is installed inside the three-section deflector duct; the filter screen can intercept cargo debris, dust and other impurities, preventing them from entering the compartment and causing pollution.

[0012] The beneficial effects of this utility model are: 1. Multi-directional adjustment and precise air delivery: This universal air delivery mechanism is designed with multiple independently rotatable reversing pipe sections. Since the reversing pipe sections are beveled pipes, the direction of the air outlet can be adjusted in multiple dimensions. It can be used in the cold storage compartments of ships. The direction of the cold air can be dynamically adjusted according to the stacking position of the cargo in the compartment to ensure that the cold air directly covers the cargo and improves the uniformity of preservation.

[0013] 2. Hierarchical coordination and wide adjustment range: The hierarchical design of the first directional pipe section (single inclined plane), the second directional pipe section (double inclined plane), and the third directional pipe section (inclined plane + plane) forms an angle adjustment capability that is gradually expanded to adapt to the complex layout requirements of ship cabins.

[0014] 3. Compact structure and strong adaptability: The multi-section tubular coaxial nested design has a low overall height and occupies little space, which meets the space constraints of the compact ship cabin; each drive component is integrated into the side wall of the tube section, which is convenient for installation and maintenance.

[0015] 4. Anti-clogging design: The filter screen inside the three-section deflector pipe can effectively intercept cargo debris, extend the service life of the pipe, and reduce the frequency of maintenance. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, a multi-segment duct-type universal air supply mechanism is provided for use in a ship's cold storage compartment. Specifically, it includes an air supply duct segment 1 and a flange 2 installed at the upper end of the air supply duct segment 1; it also includes three sets of continuously rotating deflector duct segments installed below the air supply duct segment 1 and coaxially arranged with the air supply duct segment 1, which, from top to bottom, are deflector duct segment one 3, deflector duct segment two 4, and deflector duct segment three 5; it also includes three sets of drive assemblies respectively installed on the sidewalls of the air supply duct segment 1 and the sidewalls of the deflector duct segments, driving each deflector duct segment to rotate independently, which, from top to bottom, are drive assembly one 6, drive assembly two 7, and drive assembly three 8; all deflector duct segments are oblique-ended pipes, and each set of oblique-ended pipes has at least one inclined surface. This omnidirectional air supply mechanism is designed with multiple independently rotatable deflector pipe sections. Since the deflector pipe sections are beveled pipes, the direction of the air supply outlet can be adjusted in multiple dimensions. The direction of the cold air can be dynamically adjusted according to the stacking position of the goods in the compartment to ensure that the cold air directly covers the goods and improves the uniformity of preservation.

[0020] like Figures 5 to 6As shown, the drive assembly 6 includes a base 61 fixed to the side wall of the air supply duct section 1, a motor 62 fixed to the base 61, a drive gear 63 concentrically connected to the shaft of the motor 62, and a driven gear ring 64 fixedly connected to the upper edge of the deflector section 3. The diameter of the drive gear 63 is smaller than the diameter of the driven gear ring 64. The motor 62 drives the deflector section 3 to rotate around the axis of the air supply duct section 1 through the meshing of the drive gear 63 and the driven gear ring 64. The upper surface of the deflector section 3 is a plane concentrically fitted with the lower surface of the air supply duct section 1 (to ensure airtightness), and the lower surface of the deflector section 3 is an inclined plane (the inclination angle α between it and the horizontal plane is 20°). By rotating the deflector section 3, the angle of the inclined plane of its lower surface changes, which can initially adjust the direction of the downward flow of cold air.

[0021] like Figures 6 to 7 As shown, drive assembly 2 7 includes a base 2 71 fixed to the side wall of deflector section 1 3, a motor 2 72 fixed to the base 2 71, a drive gear 2 73 concentrically connected to the shaft of motor 2 72, and a driven gear ring 2 74 fixedly connected to the upper edge of deflector section 2 4. The diameter of drive gear 2 73 is smaller than the diameter of driven gear ring 2 74. Motor 2 72 drives deflector section 2 4 to rotate around the axis of air supply duct section 1 through the meshing of drive gear 2 73 and driven gear ring 2 74. The upper surface of deflector section 2 4 is a sloped surface concentrically fitted with the lower surface of deflector section 1 3 (to ensure airtightness), and the lower surface of deflector section 2 4 is a sloped surface (the inclination angle β between it and the horizontal plane is 25°). The double-sloped surface design of deflector section 2 4 can further expand the airflow adjustment range and make the cold air flow direction more precise.

[0022] like Figures 7 to 8 As shown, the drive assembly 38 includes a base 381 fixed to the side wall of the deflector section 2 4, a motor 382 fixed to the base 381, a drive gear 383 concentrically connected to the shaft of the motor 382, ​​and a driven gear ring 384 fixedly connected to the upper edge of the deflector section 3 5. The diameter of the drive gear 383 is smaller than the diameter of the driven gear ring 384. The motor 382 drives the deflector section 3 5 to rotate around the axis of the air supply section 1 through the meshing of the drive gear 383 and the driven gear ring 384. The upper surface of the deflector section 3 5 is an inclined surface that is concentrically fitted with the lower surface of the deflector section 2 4 (to ensure airtightness), and the lower surface of the deflector section 3 5 is a plane. The outlet of its lower surface is the final air outlet, and the final air supply direction is adjusted by the rotation of the deflector section 3 5.

[0023] like Figure 8 As shown, the lower air outlet of the deflector section 35 is an inwardly contracting opening (contraction ratio 1:2); the contraction design can accelerate the cold air flow rate (flow rate increased by 20-30%), so that the cold air is concentrated and blown towards the goods, improving the local cooling efficiency.

[0024] like Figure 4 As shown, a filter screen 9 (optional) is installed inside the reversing pipe section 3 5; the filter screen 9 can intercept cargo debris, dust and other particles to prevent them from entering the compartment and causing pollution.

[0025] The working principle of the multi-segment omnidirectional air supply mechanism: When the cargo in the compartment is concentrated on the left side, the first deflector segment 3 is rotated (horizontally deflected to the left) by the drive component 6, the second deflector segment 4 is rotated (further deflected to the left) by the drive component 7, and the third deflector segment 5 is rotated (further deflected to the left) by the drive component 8, so that the air outlet is finally directed towards the cargo on the left side; similarly, if the cargo is concentrated on the lower right side, the cold air can be directed to the lower right area by the combined rotation of the deflector segments of each layer, so as to achieve precise air supply.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
