Description

Technical Field

[0001] This utility model relates to the field of marine air conditioning technology, and in particular to a dynamic stabilization and regulation device for marine air conditioning pipeline pressure. Background Technology

[0002] Marine air conditioning ducts are a core component of the ship's cabin environment control system. They are mainly used to deliver treated air to each cabin. Depending on the wind speed and layout, they are mainly divided into low-speed duct systems and high-speed duct systems.

[0003] During operation, air conditioning ducts serve as channels for air circulation. To ensure faster airflow within the ducts, some ducts are equipped with fans to accelerate airflow. However, the rotation of the fan, the collision of airflow with the duct wall, and the vibration of the fan blades can generate significant noise, affecting the cabin environment. Furthermore, since the fan is located inside the duct, maintenance is relatively troublesome. Therefore, we propose a dynamic pressure stabilization and regulation device for marine air conditioning ducts. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a dynamic pressure stabilization and regulation device for marine air conditioning pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dynamic stabilization and adjustment device for marine air conditioning pipe pressure, comprising a first pipe, a second pipe provided at one end of the first pipe, and at least one adjustment mechanism provided between the second pipe and the first pipe. The adjustment mechanism includes a first wide mask, the narrow end of which is connected to a first pipe, a connecting pipe installed at one end of the first wide mask, a second wide mask connected to the other end of the connecting pipe, the wide end of the second wide mask being fixed to the connecting pipe, and the other end of the second wide mask being fixed to a second pipe; The second wide mask has inclined guide plates on both sides inside. The two guide plates are arranged opposite each other, and one end of the guide plate is placed in the connecting tube and is rotatably connected to the inner wall of the connecting tube through a rotating shaft. A drive mechanism that drives the rotating shaft to rotate is installed on the end of the rotating shaft. Both sides of the air deflector are inclined slopes parallel to the inner wall of the second wide-face mask, and an elastic rubber plate is installed on the side of the air deflector, with the other side of the rubber plate abutting against the inner wall of the second wide-face mask.

[0006] Preferably, a chassis with openings on both sides is provided on one side of the connecting pipe. One side of the chassis with an opening is fixed to the outer wall of the connecting pipe, and an opening door is hinged to the other side of the chassis with a latch. A control box is installed on the opening and closing door, and a controller is installed inside the control box. A wind force sensor is installed on the inner wall of the narrow end of the second wide mask, and the wind force sensor is connected to the controller via a wire.

[0007] Preferably, the drive mechanism includes a first sprocket coaxially mounted on the end of a rotating shaft, and a second sprocket on each side of the two first sprockets that are relatively close to each other. The second sprockets are rotatably connected to the outer wall of the connecting pipe through a connecting shaft, and the second sprockets are connected to the first sprockets through a chain. A gear is also coaxially mounted on the connecting shaft, and the two gears mesh with each other. A drive motor is mounted on the end of one of the connecting shafts. The drive motor is fixed to the inner wall of the housing through a bracket, and the drive motor is connected to the controller through a wire.

[0008] Preferably, the first pipe and the first wide-face mask, as well as the second pipe and the second wide-face mask, are connected by flanges.

[0009] Preferably, a connecting frame is provided on the inner side of the wide-mouth end of the first wide-face mask. The end of the connecting frame is fixed to the inner wall of the first wide-face mask. A support plate is provided on the side of the connecting frame near the first pipe.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example Reference Figures 1-4 A dynamic stabilization and adjustment device for marine air conditioning pipe pressure includes a first pipe 1, a second pipe 5 at one end of the first pipe 1, and at least one adjustment mechanism between the second pipe 5 and the first pipe 1.

[0018] The regulating mechanism includes a first wide-mouth mask 2, the narrow end of which is connected to a first pipe 1. A connecting pipe 3 is installed at one end of the first wide-mouth mask 2, and the other end of the connecting pipe 3 is connected to a second wide-mouth mask 4. The wide end of the second wide-mouth mask 4 is fixed to the connecting pipe 3, and the other end of the second wide-mouth mask 4 is fixed to a second pipe 5. After air enters the first wide-mouth mask 2 from the first pipe 1, some air will flow along the inner wall of the first wide-mouth mask 2 and diffuse outward, thereby accumulating the air entering the regulating mechanism. As the air continues to flow, after the air comes into contact with the second wide-mouth mask 4, the air will again gather towards the center along the inner wall of the second wide-mouth mask 4, thereby compressing the air and increasing the flow rate of the air into the second pipe 5.

[0019] Specifically, the first pipe 1 and the first wide-angle mask 2, as well as the second pipe 5 and the second wide-angle mask 4, are connected by flanges, allowing the adjustment mechanism to be detachably installed between the first pipe 1 and the second pipe 5. Therefore, more than one adjustment mechanism can be set between the first pipe 1 and the second pipe 5, so that the airflow speed can be increased multiple times.

[0020] like Figure 3 and Figure 4 As shown, inclined guide plates 6 are provided on both sides inside the second wide mask 4. The two guide plates 6 are arranged opposite each other, and one end of the guide plate 6 is placed in the connecting pipe 3 and is rotatably connected to the inner wall of the connecting pipe 3 through a rotating shaft 7. A drive mechanism that drives the rotating shaft 7 to rotate is installed on the end of the rotating shaft 7. After the air enters the connecting pipe 3 from the first pipe 1, it will contact the guide plate 6 and flow along the surface of the guide plate 6. The air flow in the regulating mechanism can be compressed twice, thereby increasing the rate at which the air flows out between the two guide plates 6. This reduces costs, facilitates maintenance, and reduces noise generation. Furthermore, due to the rotation adjustment of the guide plate 6 by the drive mechanism, the gap between the two guide plates 6 can be adjusted to achieve dynamic adjustment of the pipe pressure.

[0021] The connecting pipe 3 has a housing 14 with openings on both sides. One side of the housing 14 is fixed to the outer wall of the connecting pipe 3. The other side of the housing 14 is hinged to an opening door 15. The other side of the opening door 15 is connected to the housing 14 by a latch. A control box 24 is installed on the opening door 15. The control box 24 contains a controller. In actual use, the controller is one of a PLC logic controller, a control motherboard, or a control host. The controller is also connected to the controller of the marine air conditioner through wires so that the rotation of the guide plate 6 can be directly controlled by adjusting the air conditioner.

[0022] Specifically, the drive mechanism includes a first sprocket 8 coaxially mounted on the end of the rotating shaft 7. A second sprocket 9 is provided on the side of the two first sprockets 8 that are relatively close to each other. The second sprocket 9 is rotatably connected to the outer wall of the connecting pipe 3 through a connecting shaft 10, and the second sprocket 9 is connected to the first sprocket 8 through a chain 11. A gear 12 is also coaxially mounted on the connecting shaft 10, and the two gears 12 mesh with each other. A drive motor 13 is mounted on the end of one of the connecting shafts 10. The drive motor 13 is fixed to the inner wall of the housing 14 through a bracket, and the drive motor 13 is connected to the controller through a wire. The same drive motor 13 drives the two guide plates 6 to perform relative deflection operations.

[0023] It should be noted that both sides of the deflector plate 6 are inclined slopes parallel to the inner wall of the second wide-face mask 4, and an elastic rubber plate 16 is installed on the side of the deflector plate 6. The other side of the rubber plate 16 abuts against the inner wall of the second wide-face mask 4. The flexible and elastic rubber plate 16 fills the gap between the deflector plate 6 and the inner wall of the second wide-face mask 4, ensuring that the air entering the connecting pipe 3 will fall fully onto the deflector plate 6 and act, and will not flow out from the gap between the deflector plate 6 and the second wide-face mask 4.

[0024] Furthermore, a baffle 25 is provided on the side of the guide plate 6 near the first pipe 1. The baffle 25 is fixed to the inner wall of the connecting pipe 3, and the side of the baffle 25 near the first pipe 1 is an inclined surface, which guides the air flow on the inner wall of the connecting pipe 3 to the guide plate 6, ensuring that the air entering the connecting pipe 3 is in full contact with the guide plate 6.

[0025] It should be further explained that a wind sensor is installed on the inner wall of the narrow end of the second wide mask 4. The wind sensor is connected through a wire controller and can monitor the airflow speed into the second pipe 5 so as to enable intelligent automatic control of the adjustment mechanism.

[0026] It should be noted that, as Figure 3 and Figure 4 As shown, when air enters the first wide-mouth mask 2, a connecting frame 17 is provided on the inner side of the wide-mouth end of the first wide-mouth mask 2. The end of the connecting frame 17 is fixed to the inner wall of the first wide-mouth mask 2, and a support plate 18 is provided on the side of the connecting frame 17 near the first pipe 1. Several sleeves 21 arranged at intervals are vertically installed on one side of the support plate 18. A guide shaft 22 is built into the other end of the sleeve 21. The other end of the guide shaft 22 is fixed to the connecting frame 17, and a compression spring 23 is sleeved on the guide shaft 22. One end of the compression spring 23 is fixed to the support plate 18, and the other end of the compression spring 23 is fixed to the connecting frame 17. On the other side of 8, an elastic rubber block 19 is installed, and a sealing ring 20 is provided along the outer side of the rubber block 19. The sealing ring 20 is fixed on the inner wall of the narrow end of the first wide-face mask 2. The sealing ring 20 and the rubber block 19 are connected. When air enters the first wide-face mask 2, it will move the support plate 18 towards the connecting pipe 3. With the conical structure of the first wide-face mask 2, the air can flow along the inner wall of the first wide-face mask 2. When air flows from the second pipe 5 to the first pipe 1, the air will act on the support plate 18 to press the rubber block 19 against the sealing ring 20, thereby sealing the first wide-face mask 2 to prevent backflow of air in the pipe.

[0027] Furthermore, an arc-shaped cut surface is provided on the edge of the connecting frame 17 near the first pipe 1, so that the air can flow more smoothly along the surface of the connecting frame 17 after contacting the connecting frame 17, reducing the resistance of the connecting frame 17 to the air flow.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
