Description

Technical Field

[0001] This utility model relates to the field of air conditioning ducts, and in particular to a structure for an air conditioning ventilation duct in a ship cabin. Background Technology

[0002] With the rapid development of the marine equipment manufacturing industry, various ships and offshore platforms have increasingly higher requirements for cabin comfort, and marine central air conditioning has been widely used. A central air conditioning system consists of one or more cold / heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners, this system centrally processes air to achieve comfort requirements, using the principle of liquid vaporization refrigeration to provide the necessary cooling capacity to offset the heat load of the indoor environment. The heating system provides the necessary heat to offset the heating / cooling load of the indoor environment.

[0003] In existing technologies, ship cabin air conditioning and ventilation systems need to achieve efficient airflow delivery within the limited space of the bulkhead. The installation of ducts is limited by the bulkhead space and can only be installed in the gap between the two sides of the bulkhead. Furthermore, during installation, the air outlet is generally located on the bulkhead near the ceiling.

[0004] During the installation of ventilation ducts, installation is only required on one plane in the same layer, and only right-angle bends are needed in each compartment. However, turbulent vortices are easily generated at the right-angle bends of the installed ducts, increasing local resistance and affecting the air conditioning ventilation effect. At the same time, the duct support structure is prone to loosening under ship vibration environment, and the asymmetrical bulkhead layout results in poor versatility of the installation components on both sides of the ship's compartment. Therefore, a ship compartment air conditioning ventilation duct structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art, and thus proposes a ventilation duct structure for ship cabin air conditioning. This invention, by setting up an airflow stabilizing component and installing adjusting blocks at the right-angle connections of the pipes, uses crescent-shaped adjusting blocks embedded in the pipe bends to change the local cross-sectional shape, making it similar to the cross-section of the flattened round pipe, guiding the airflow to a smooth direction. Simultaneously, T-shaped connecting blocks stably fix the adjusting blocks to the two sets of pipes, and magnetic strips are used to firmly adhere them to the inner wall of the pipes, ensuring that the adjusting blocks do not shift under the impact of high-speed airflow, thereby improving the stability of the gas flow inside the pipe.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The air conditioning ventilation duct structure for a ship's cabin includes a pipe, the pipe being flat and round in shape. One end of the pipe is fixedly connected to a flange, and the other end of the pipe is fixedly connected to a flange. Two sets of pipes are provided, and an airflow stabilizing component is installed at the right-angle connection between the two sets of pipes. The airflow stabilizing component includes a fixing groove, which is formed on the inner wall of the pipe. A connecting block is detachably connected to the inner wall of the fixing groove. An adjusting block is fixedly connected to the top of the connecting block, and a magnetic strip is fixedly connected to the outer wall of the adjusting block.

[0008] Preferably, the outer wall of the pipe is provided with an installation assembly, the installation assembly including a connecting ring, the connecting ring being fixedly connected to the outer wall of the pipe, the outer wall of the connecting ring being fixedly connected to an installation block, the outer wall of the connecting ring being provided with an installation seat, and the top of the installation seat being fixedly connected to a fixing block.

[0009] Preferably, the adjusting block is crescent-shaped to change the cross-sectional shape at the bend, making it the same as the cross-section of the pipe.

[0010] Preferably, the connecting block is T-shaped.

[0011] Preferably, a sealing block is inserted into the inner wall of the fixing groove to block the fixing groove when the adjusting block is not required.

[0012] Preferably, the inner wall of the mounting base has a slot, and the connecting ring is inserted into the inner wall of the slot.

[0013] Preferably, the mounting base is T-shaped and is used to install on the bulkhead of the ship's cabin and to support and fix the ventilation duct structure.

[0014] Preferably, the end of the pipe furthest from the flange is inclined.

[0015] Preferably, the second flange is inclined.

[0016] Preferably, the mounting blocks are provided in two sets, and the two sets of mounting blocks are symmetrically arranged with the center line of the connecting ring as the axis of symmetry.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting up an airflow stabilizing component, an adjusting block is installed at the right-angle connection of the pipe. The crescent-shaped adjusting block is embedded in the bend of the pipe to change the local cross-sectional shape, making it similar to the cross-section of the flat round pipe, thus guiding the airflow to turn smoothly. At the same time, the T-shaped connecting block stably fixes the adjusting block on the two sets of pipes, and then uses a magnetic strip to stably attach it to the inner wall of the pipe, ensuring that the adjusting block does not shift under the impact of high-speed airflow, thereby improving the stability of the gas flow inside the pipe.

[0019] 2. In this utility model, by setting up an installation component, two sets of installation blocks are symmetrically distributed on both sides of the connecting ring. Regardless of whether the mounting base is fixed to the left or right side of the bulkhead, the installation blocks and the fixing blocks can be locked together by bolts. This allows users to choose a suitable installation position according to their installation needs, so as to adapt to the asymmetrical layout of the ship's cabin and improve the installation versatility of the device.

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an embodiment of a ship cabin air conditioning ventilation duct structure, including a pipe 1 for air conditioning ventilation. The pipe 1 is shaped as a flattened oval. Compared with a rectangular pipe, the flattened oval pipe 1 has less airflow resistance and can provide better airflow performance in a limited height space. At the same time, compared with a circular pipe, it can make better use of the space of the cabin wall. One end of the pipe 1 is fixedly connected to a flange 2, which allows the pipe 1 to connect with the flange 2 of an adjacent pipe 1. The other end of the pipe 1 is fixedly connected to a flange 3, which can allow the pipe 1 to be connected in a straight line or to connect the internal channels in a right-angle bend. There are two sets of pipe 1. An airflow stabilizing component 4 is installed at the right-angle connection of the two sets of pipe 1. When the two sets of pipe 1 are connected in a right-angle bend, the airflow stabilizing component 4 can make the gas flow more stable. The airflow stabilizing component 4 includes a fixing groove 41, which is used for... Adjusting block 43 is installed on pipe 1. Fixing groove 41 is opened on the inner wall of pipe 1 so that the installed adjusting block 43 fits the inner wall of pipe 1. Connecting block 42 is detachably connected to the inner wall of fixing groove 41. Connecting block 42 is used to fix adjusting block 43 stably on pipe 1. Adjusting block 43 that changes the cross-sectional size of the bend is fixedly connected to the top of connecting block 42. During installation, first take the sealing block 6 out of fixing groove 41. Then, insert the connecting block 42 on adjusting block 43 into the inside of one set of fixing groove 41 of pipe 1. Then, let the other set of fixing groove 41 of pipe 1 be vertically fitted onto sealing block 6. Finally, connect the two sets of flanges 2 3. Magnetic strip 44 is fixedly connected to the outer wall of adjusting block 43. When the material of pipe 1 is iron material that magnetic strip 44 can attract, magnetic strip 44 can stabilize the edge of adjusting block 43. If pipe 1 is not iron material, another set of magnetic strip 44 can be installed inside pipe 1 to ensure the stability of adjusting block 43.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, the outer wall of pipe 1 is provided with an installation assembly 5 for mounting pipe 1 on the bulkhead of the ship's hold. When fixing pipe 1 to the bulkhead of the ship's hold, it can be installed on the two side bulkheads according to the installation requirements. The installation assembly 5 includes a connecting ring 51, which cooperates with the mounting block 52 to fix pipe 1 to the mounting base 53. The connecting ring 51 is fixedly connected to the outer wall of pipe 1 for fixing it to the mounting base 53. The outer wall of the connecting ring 51 is fixedly connected with the mounting block 52, which is used to connect the mounting base 53 and stably fix the connecting ring 51 in the slot 7 inside the mounting base 53. The outer wall of the connecting ring 51 is provided with a mounting base 53 for installing and supporting other components. The top of the mounting base 53 is fixedly connected with a fixing block 54, which is fixed during installation. Block 54 is attached to mounting block 52, and then the two are fixed together with bolts. The inner wall of mounting base 53 has a slot 7. The connecting ring 51 is inserted into the inner wall of mounting base 53 through the slot 7 to ensure that mounting base 53 is aligned. The connecting ring 51 is inserted into the inner wall of slot 7. After the connecting ring 51 is inserted into mounting base 53, mounting base 53 supports and fixes the connecting ring 51 while supporting and fixing the pipe 1. The shape of mounting base 53 is set as T-shaped, which is used to install on the bulkhead of the ship's cabin and to support and fix the ventilation duct structure. It is more stable after installation. There are two sets of mounting blocks 52. The two sets of mounting blocks 52 are symmetrically arranged with the center line of connecting ring 51 as the axis of symmetry. No matter which side the mounting base 53 is installed on, the mounting block 52 can be attached to the fixing block 54 for fixation.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the adjusting block 43 is crescent-shaped to change the cross-sectional shape at the bend, making it the same as the cross-section of pipe 1. The changed cross-section allows the airflow to flow more stably and reduces flow resistance. The connecting block 42 is T-shaped to reduce shaking when inserted into the fixing groove 41. The inner wall of the fixing groove 41 is fitted with a sealing block 6 to block the fixing groove 41 when the adjusting block 43 is not needed. The end of pipe 1 away from flange 2 is inclined, allowing the two sets of pipes 1 to be connected vertically. When a straight connection is required, the two sets of pipes 1 are rotated at right angles on the same horizontal line to achieve a horizontal connection of the inclined surfaces. Flange 3 is inclined to connect the inclined parts of pipe 1.

[0034] Working principle: In use, a flat oval pipe 1 is used as the main ventilation channel. Its cross-sectional shape combines the advantages of low resistance of a circular pipe and spatial adaptability of a rectangular pipe. The flat oval streamlined inner wall reduces airflow friction and vortex generation, improving ventilation efficiency per unit cross-section. It maximizes the use of installation space within the limited height of the ship's cabin wall, increasing horizontal space utilization compared to a circular pipe and reducing airflow energy loss compared to a rectangular pipe. During installation, the same ends of the two sets of pipes 1 are connected together. When pipe 1 extends to the point affecting the bend, the adjusting block 43 is first installed at the connection, and the sealing block 6 is removed from the fixing groove 41. Then, the connecting block 4 on the adjusting block 43 is first removed. 2. Insert the fixing groove 41 of one set of pipes 1 into the inside, and then let the fixing groove 41 of the other set of pipes 1 be vertically fitted onto the sealing block 6. Finally, connect the two sets of flanges 2 3. The crescent-shaped adjusting block 43 is embedded in the bend of pipe 1. By changing the local cross-sectional shape (making it similar to the cross-section of the flat round pipe 1), the airflow is guided to turn smoothly and turbulence is suppressed. If pipe 1 is made of iron, the magnetic strip 44 directly adsorbs the adjusting block 43 on the inner wall of pipe 1. If pipe 1 is not made of iron, an additional magnetic strip 44 is added to the inner wall of pipe 1 to ensure that the adjusting block 43 does not shift under the impact of high-speed airflow. The T-shaped connecting block 42 is inserted into the fixing groove 41 to form Three-point positioning eliminates the vibration risk of adjusting block 43. Flange 2 at both ends of pipe 1 connects with the flange of adjacent pipe 1 to form a continuous straight path. The inclined end of pipe 1 mates with flange 3. When a straight connection is required, the two sets of pipes 1 are rotated at right angles on the same horizontal line to achieve a horizontal connection of the inclined surfaces. While a straight connection is possible, a vertical turn can also be achieved through the inclined interface. At this time, the airflow stabilizing component 4 is activated simultaneously to ensure the stability of the flow field in the turning area. The connecting ring 51 is inserted into the slot 7 of the T-shaped mounting seat 53 to achieve self-weight support and lateral limitation of pipe 1. Two sets of mounting blocks 52 are symmetrically distributed on both sides of the connecting ring 51. Regardless of whether the mounting base 53 is fixed to the left or right side of the bulkhead, the mounting block 52 and the fixing block 54 can be locked together with bolts to adapt to the asymmetrical layout of the cabin. The T-shaped mounting base 53 provides a wide base support to resist vibration and overturning moment during ship navigation. The sealing block 6 is embedded in the fixing groove 41 when a right-angle connection is not required, keeping the inner wall of the pipe 1 smooth and avoiding airflow disturbance. Through the triple synergy of the flat round pipe 1, the adjustable steering component and the symmetrical mounting system, air conditioning ventilation with low resistance, high space utilization and strong vibration adaptability is achieved in the narrow space of the ship. In particular, it solves the problem of airflow energy loss in the right-angle turning area and improves the energy efficiency of the entire ship's air conditioning system.
