Description

Technical Field

[0001] This utility model relates to the field of marine ventilation equipment technology, specifically to an air outlet plate of a marine air distributor with rainproof function. Background Technology

[0002] An air distributor is a device that delivers air from an air conditioner into the cabin and mixes it evenly with the indoor air. The air outlet plate is generally a square or round plate with several ventilation holes. The air outlet plate is installed at the air outlet of the air distributor and uses several ventilation holes to disperse the air coming out of the air outlet of the air distributor, so as to facilitate its even mixing with the indoor air.

[0003] A search revealed Chinese Patent Publication No. CN214776497U, which discloses an air outlet plate for a marine air distributor. The plate includes a plate body with an internal air supply chamber. An air inlet pipe is located at the top of the plate body, connecting to the air outlet of the air distributor. Air outlets are located on all four side walls of the plate body, and air delivery plates are located at each outlet. The side of the air delivery plate away from the air inlet pipe is hinged to the bottom of the air outlet. A drive assembly for rotating the air delivery plates is located on the side walls of the plate body. This application, by providing air outlets on all four side walls of the plate body and rotatable air delivery plates at each outlet, allows air from inside the air distributor to pass through... The air inlet duct enters the air supply chamber and exits from the air outlet. The side of the air supply plate away from the air inlet duct is hinged to the bottom of the air outlet and a drive component is installed to adjust the angle of the air supply plate, thereby adjusting the air outlet angle so that the delivered air blows towards the top of the cabin, reducing the possibility of direct airflow onto the people inside the cabin and improving the comfort of the people inside the cabin when the air is supplied. However, due to the changeable weather at sea, especially in the case of heavy rain or splashing waves, traditional marine air distributors cannot effectively prevent rainwater from entering the cabin, leading to equipment damage, damp environment and other problems, which seriously affect the safety and comfort of passengers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air outlet plate for a marine wind diffuser with rainproof function. It has advantages such as rainproof function and solves the problem that traditional marine wind diffusers cannot effectively prevent rainwater from entering the cabin due to the changeable weather at sea, especially in the case of heavy rain or splashing waves, which leads to equipment damage, damp environment and seriously affects passenger safety and comfort.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air outlet plate for a marine air distributor with a rainproof function, comprising a main frame, an air inlet chamber connected to the middle of the upper side of the main frame, a drive motor fixed to the right side wall of the inner cavity of the air inlet chamber, a rotating blade fixed to the output shaft of the drive motor, multiple air inlets on the left side of the air inlet chamber, rainproof mechanisms for protecting the main frame from rain at both ends of the upper surface of the main frame, and an adjustment mechanism for adjusting the air outlet angle at the middle between the opposite sides of the inner top wall and the inner bottom wall of the main frame.

[0006] The rainproof mechanism includes two support rods, a fixed plate, two movable plates, two limiting plates, two support plates, a dual-axis motor, two lead screws, and two connecting blocks. The two support rods are fixed to the left and right ends of the upper surface of the main frame. The fixed plate is fixed to the upper surface of the two support rods. The two movable plates are slidably connected to the left and right ends of the inner cavity of the fixed plate. The two limiting plates are respectively fixed to the opposite sides of the two movable plates. The two support plates are respectively fixed to the left and right ends of the inner bottom wall of the fixed plate. The dual-axis motor is fixed to the middle of the inner bottom wall of the fixed plate. The two lead screws are respectively fixed to the two output shafts of the dual-axis motor. The connecting blocks are threadedly connected to the lead screws. The back of the connecting blocks is fixed to the movable plates.

[0007] By adopting this technical solution, the position of the two movable plates can be adjusted through the rainproof mechanism, so that the two movable plates and the fixed plate can completely cover the main frame, which significantly improves the waterproof performance of the marine wind diffuser in the face of severe weather conditions and reduces the equipment failure rate and maintenance costs caused by rainwater intrusion.

[0008] Furthermore, air outlets are provided on three sides of the main frame, and air guide plates are hinged to the inner top walls of the air outlets.

[0009] Furthermore, the fixed plate is a cuboid with a hollow interior and missing left and right sides, and the length of the limiting plate in the vertical direction is greater than the length of the movable plate in the vertical direction.

[0010] By adopting this technical solution, the movement distance of the movable plate can be limited.

[0011] Furthermore, the two lead screws are rotatably connected to the support plate on opposite sides via bearings, and the two connecting blocks are symmetrically distributed on the left and right sides of the vertical central axis of the dual-axis motor.

[0012] This technical solution allows for the simultaneous movement of two movable panels.

[0013] Furthermore, the bottom wall of the fixed plate is provided with sliding grooves at both ends, and a slider is fixed on the lower surface of the connecting block. The slider moves horizontally in the inner cavity of the sliding groove.

[0014] By adopting this technical solution, the slider and groove can limit the movement of the connecting block, allowing it to move only in a straight line.

[0015] Furthermore, the adjustment mechanism includes a threaded rod, a driven bevel gear, a driving bevel gear, a drive rod, a screw sleeve, and three lifting rods. The threaded rod is rotatably connected to the middle of the inner top wall and the inner bottom wall of the main frame via a bearing. The driven bevel gear is fixed to the bottom of the outer surface of the threaded rod. The driving bevel gear is meshed with the upper surface of the driven bevel gear. The drive rod is fixed to the inner cavity of the driving bevel gear. The screw sleeve is threadedly connected to the threaded rod. The three lifting rods are respectively fixed to three sides of the screw sleeve.

[0016] By adopting this technical solution, the adjustment mechanism can adjust the height of the lifting rod, thereby changing the angle of the air guide plate and thus changing the angle of the air passing through the air outlet, reducing the possibility of direct airflow onto the occupants of the cabin and improving passenger comfort.

[0017] Furthermore, the front of the drive rod extends through and to the front side of the main frame, and the length of the lifting rod is greater than half the length of the inner cavity of the main frame.

[0018] By adopting this technical solution, it becomes easier for staff to drive the rotation of the active bevel gear.

[0019] Furthermore, a positioning plate is fixed to the lower surface of the threaded sleeve, and a through hole is opened on the upper surface of the positioning plate. The inner diameter of the through hole is larger than the outer diameter of the threaded rod. Telescopic sleeve rods are fixed at both ends of the positioning plate and the opposite side of the inner top wall of the main frame.

[0020] By adopting this technical solution, the telescopic sleeve and the positioning plate can limit the movement of the screw sleeve, so that it can only move linearly up and down.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. The air outlet plate of this marine wind diffuser with rainproof function can adjust the position of the two movable plates through the rainproof mechanism, so that the two movable plates and the fixed plate can completely cover the main frame, which significantly improves the waterproof performance of the marine wind diffuser in the face of severe weather conditions and reduces the equipment failure rate and maintenance costs caused by rainwater intrusion.

[0023] 2. The air outlet plate of this marine air diffuser with rainproof function has an adjustment mechanism that can adjust the height of the lifting rod, thereby changing the angle of the air guide plate and thus changing the angle of the air passing through the air outlet, reducing the possibility of direct airflow to the occupants of the cabin and improving passenger comfort.

[0029] 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.

[0030] Please see Figure 1 The air outlet plate of a marine air distributor with rainproof function in this embodiment includes a main frame 1. An air inlet chamber 2 is connected to the middle of the upper side of the main frame 1. A drive motor 3 is fixed to the right side wall of the inner cavity of the air inlet chamber 2. A rotating blade 4 is fixed to the output shaft of the drive motor 3. Multiple air inlets 5 are opened on the left side of the air inlet chamber 2. Rainproof mechanisms 6 for rainproofing the main frame 1 are provided at both ends of the upper surface of the main frame 1. An adjustment mechanism 7 for adjusting the air outlet angle is provided in the middle between the opposite sides of the inner top wall and the inner bottom wall of the main frame 1.

[0031] In this embodiment, air outlets are provided on three sides of the main frame 1, and air guide plates are hinged to the inner top walls of the air outlets.

[0032] It should be noted that the drive motor 3 is started by controlling the external controller. The output shaft of the drive motor 3 rotates, which drives the rotating blade 4 to rotate, thereby realizing the air volume adjustment. The rotating blade 4 draws air into the inner cavity of the main frame 1 through the air inlet 5. At this time, the air can be dispersed through multiple air outlets under the action of multiple air guide plates.

[0033] Please see Figures 2 to 3 To improve the waterproof performance of the marine wind diffuser in severe weather conditions, the rainproof mechanism 6 in this embodiment includes two support rods 61, a fixed plate 62, two movable plates 63, two limiting plates 64, two support plates 65, a dual-axis motor 66, two lead screws 67, and two connecting blocks 68. The two support rods 61 are fixed to the left and right ends of the upper surface of the main frame 1. The fixed plate 62 is fixed to the upper surface of the two support rods 61. The two movable plates 63 are slidably connected to the left and right ends of the inner cavity of the fixed plate 62. The two limiting plates 64 are respectively fixed to the opposite sides of the two movable plates 63. Plates 65 are fixed to the left and right ends of the inner bottom wall of fixed plate 62, and dual-axis motor 66 is fixed to the middle of the inner bottom wall of fixed plate 62. Two lead screws 67 are fixed to the two output shafts of dual-axis motor 66, respectively. Connecting block 68 is threadedly connected to lead screw 67. The back of connecting block 68 is fixed to movable plate 63. When dual-axis motor 66 is started, the output shaft of dual-axis motor 66 rotates, which drives the two lead screws 67 to rotate. The rotation of lead screw 67 causes the connecting block 68 threadedly connected to its surface to move. At this time, the two connecting blocks 68 move in opposite directions. The movement of connecting block 68 synchronously drives movable plate 63 to move.

[0034] In this embodiment, the fixed plate 62 is a cuboid with a hollow interior and missing left and right sides. The length of the limiting plate 64 in the vertical direction is greater than the length of the movable plate 63 in the vertical direction. The two lead screws 67 are rotatably connected to the support plate 65 on opposite sides through bearings. The two connecting blocks 68 are symmetrically distributed on the left and right sides of the vertical central axis of the dual-axis motor 66.

[0035] It is understandable that the two movable plates 63 move in opposite directions and move out of the inner cavity of the fixed plate 62 until the two movable plates 63 and the fixed plate 62 completely cover the main frame 1, thereby preventing rainwater from entering the inner cavity of the main frame 1.

[0036] In addition, the widths of the movable plate 63 and the fixed plate 62 are both greater than the width of the main frame 1, the two output shafts of the dual-axis motor 66 rotate in the same direction, and the threads on the surfaces of the two lead screws 67 are in opposite directions.

[0037] The bottom wall of the fixed plate 62 has grooves on both the left and right ends, and the lower surface of the connecting block 68 is fixed with a slider, which moves horizontally in the inner cavity of the groove.

[0038] It should be noted that by adjusting the position of the two movable plates 63, the two movable plates 63 and the fixed plate 62 can completely cover the main frame 1, which significantly improves the waterproof performance of the marine wind diffuser in the face of severe weather conditions and reduces the equipment failure rate and maintenance costs caused by rainwater intrusion.

[0039] Please see Figure 4 To change the angle of the airflow through the outlet, the adjustment mechanism 7 in this embodiment includes a threaded rod 71, a driven bevel gear 72, a driving bevel gear 73, a drive rod 74, a screw sleeve 75, and three lifting rods 76. The threaded rod 71 is rotatably connected to the middle of the inner top wall and the inner bottom wall of the main frame 1 via a bearing. The driven bevel gear 72 is fixed to the bottom of the outer surface of the threaded rod 71. The driving bevel gear 73 is meshed with the upper surface of the driven bevel gear 72. The drive rod 74 is fixed to the inner cavity of the driving bevel gear 73. By rotating the drive rod 74, the rotation of the drive rod 74 causes the driving bevel gear 73 to move. The rotation of gear 73 causes the driven bevel gear 72, which meshes with it, to rotate. The rotation of the driven bevel gear 72 causes the threaded rod 71, which is fixed in its inner cavity, to rotate. The threaded sleeve 75 is threadedly connected to the threaded rod 71. Three lifting rods 76 are fixed on three sides of the threaded sleeve 75 respectively. The rotation of the threaded rod 71 causes the threaded sleeve 75, which is threadedly connected to its surface, to move up or down, thereby driving the three lifting rods 76 to rise or fall. While the three lifting rods 76 are rising or falling, they will push the air guide plate, thereby changing the angle of the air guide plate and thus changing the blowing angle.

[0040] In this embodiment, the front of the drive rod 74 extends through and to the front side of the main frame 1, the length of the lifting rod 76 is greater than half the length of the inner cavity of the main frame 1, the lower surface of the threaded sleeve 75 is fixed with a positioning plate, the upper surface of the positioning plate is provided with a through hole, the inner diameter of the through hole is greater than the outer diameter of the threaded rod 71, and telescopic sleeve rods are fixed at both ends of the positioning plate and the opposite side of the inner top wall of the main frame 1.

[0041] It should be noted that the telescopic sleeve and the positioning plate can limit the movement of the screw sleeve 75, so that it can only move linearly up and down. The telescopic sleeve includes a fixed rod and a moving rod nested together.

[0042] It is understandable that adjusting the height of the lifting rod 76 changes the angle of the air guide plate, which in turn changes the angle of the air passing through the air outlet, reducing the possibility of direct airflow onto the occupants of the cabin and improving passenger comfort.

[0043] The working principle of the above embodiments is as follows:

[0044] (1) When in use, the drive motor 3 is started by controlling the external controller. The output shaft of the drive motor 3 rotates and drives the rotating blade 4 to rotate, thereby realizing the air volume adjustment. The rotating blade 4 draws air into the inner cavity of the main frame 1 through the air inlet 5. At this time, the air can be dispersed through multiple air outlets under the action of multiple air guide plates. When adjusting the angle of the air guide plate, the drive rod 74 is rotated. The rotation of the drive rod 74 causes the active bevel gear 73 to rotate. The rotation of the active bevel gear 73 causes the driven bevel gear 72 connected to it to rotate. The rotation of the driven bevel gear 72 causes the threaded rod 71 fixed in its inner cavity to rotate. The rotation of the threaded rod 71 causes the threaded sleeve 75 connected to its surface to move up or down, thereby driving the three lifting rods 76 to rise or fall. The three lifting rods 76 push the air guide plate while rising or falling, thereby changing the angle of the air guide plate and thus changing the blowing angle.

[0045] (2) In the event of heavy rain or splashing waves, by starting the dual-axis motor 66, the output shaft of the dual-axis motor 66 rotates and drives the two lead screws 67 to rotate. The rotation of the lead screws 67 causes the connecting blocks 68 threaded on their surfaces to move. At this time, the two connecting blocks 68 move in opposite directions. The movement of the connecting blocks 68 synchronously drives the movable plate 63 to move, so that the two movable plates 63 move in opposite directions and move out of the inner cavity of the fixed plate 62 until the two movable plates 63 and the fixed plate 62 completely cover the main frame 1, thereby preventing rainwater from entering the inner cavity of the main frame 1.
