Description

Technical Field

[0001] This utility model relates to the technical field of marine ventilation systems, specifically a marine ventilation system with uniform air delivery. Background Technology

[0002] The function of engine room ventilation systems is to reduce engine room temperature, remove oil fumes and water vapor, and supply sufficient fresh air to ensure the normal operation of the power plant and improve the working and sanitary conditions of engine room personnel. Common terminal ventilation systems in shipboard living quarters, residential cabins, and work cabins all employ a top-down airflow method.

[0003] Ventilation ducts typically have diffuser systems installed at their outlets to distribute the incoming air evenly into the interior space. In existing technologies, some marine interior spaces have low ceilings and are quite large. However, the fixed airflow angle of existing diffuser systems makes them unadjustable, resulting in poor versatility. Therefore, we have developed a marine ventilation system that provides uniform airflow. Utility Model Content

[0004] The purpose of this invention is to provide a marine ventilation system with uniform air delivery. The air guide plate can be adjusted according to the size of the indoor space, making it highly versatile and thus enabling more uniform air delivery and improving ventilation efficiency, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A marine ventilation system with uniform air delivery includes a ventilation duct. A support block is provided in the middle of the air outlet of the ventilation duct. The side wall of the support block is fixedly connected to the ventilation duct by four support rods. The bottom of each of the four support rods is rotatably connected to multiple air guide plates by hinges. A linkage rod is provided below each of the four support rods. The upper side wall of each linkage rod is rotatably connected to the lower end of the corresponding multiple air guide plates by pins. An adjustment mechanism is provided between the support block and the multiple linkage rods.

[0007] Furthermore, the adjustment mechanism includes a rotating shaft and a turntable. One end of the rotating shaft is rotatably connected to the bottom of the support block through a rolling bearing. The turntable is fixedly mounted on the shaft wall, and the turntable and the linkage rod are located on the same horizontal plane. Four wedge-shaped blocks are evenly provided on the side wall of the turntable. The wedge-shaped blocks are provided with multiple limiting grooves that cooperate with the ends of the linkage rod on the side away from the turntable.

[0008] Furthermore, a rotating wheel is fixedly provided at the lower end of the rotating shaft.

[0009] Furthermore, the sidewall of the wheel is provided with multiple anti-slip protrusions.

[0010] Furthermore, a spring is fixedly installed between the bottom of the support rod and the air guide plate.

[0011] Furthermore, the end of the linkage rod near the turntable is designed with a rounded head.

[0012] Furthermore, the air guide plate is configured as an isosceles trapezoid.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This marine ventilation system, designed for uniform air distribution, utilizes a combination of air guides, ventilation ducts, linkage rods, support blocks, support rods, rotating wheels, turntables, limiting grooves, wedge blocks, springs, and a rotating shaft. Air blown into the ventilation ducts is guided to various directions by multiple air guides. When air needs to be directed further, the rotating wheel is rotated, causing the rotating shaft to rotate, which in turn rotates the turntable. The turntable then rotates multiple wedge blocks. The rounded ends allow the linkage rods to slide out of the limiting grooves, moving them away from the turntable and causing the air guides to rotate to a more horizontal position. This further directs the air from the ventilation ducts to a more distant direction. The air guiding range of the air guides can be adjusted according to the size of the indoor space, making it highly versatile and resulting in more uniform air distribution and improved ventilation.

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution:

[0023] A marine ventilation system with uniform air delivery includes a ventilation pipe 2. A support block 4 is provided in the middle of the air outlet of the ventilation pipe 2. The side wall of the support block 4 is fixedly connected to the ventilation pipe 2 by four support rods 5. The bottom of each of the four support rods 5 is rotatably connected to multiple air guide plates 1 by hinges. The air guide plates 1 are set as isosceles trapezoids between the multiple air guide plates 1. The isosceles trapezoidal design of the air guide plates 1 can improve the air guiding efficiency. A linkage rod 3 is provided below each of the four support rods 5. The upper side wall of the linkage rod 3 is rotatably connected to the lower end of the corresponding multiple air guide plates 1 by pins. A spring 10 is fixed between the bottom of the support rod 5 and the air guide plate 1. The spring 10 can push the air guide plate 1 and drive the linkage rod 3 to abut against the limiting groove 8.

[0024] An adjustment mechanism is provided between the support block 4 and the multiple linkage rods 3. The adjustment mechanism includes a rotating shaft 11 and a turntable 7. One end of the rotating shaft 11 is rotatably connected to the bottom of the support block 4 through a rolling bearing. The turntable 7 is fixedly mounted on the shaft wall of the rotating shaft 11, and the turntable 7 and the linkage rods 3 are located on the same horizontal plane. Four wedge-shaped blocks 9 are evenly provided on the side wall of the turntable 7. The side of the wedge-shaped blocks 9 away from the turntable 7 has multiple limiting grooves 8 that cooperate with the ends of the linkage rods 3. The rotation angle of multiple air guide plates 1 can be adjusted simultaneously through the adjustment mechanism. A rotating wheel 6 is fixedly provided at the lower end of the rotating shaft 11. The rotating wheel 6 facilitates the operator to rotate the rotating shaft 11, thereby driving the turntable 7 to rotate. The side wall of the rotating wheel 6 has multiple anti-slip protrusions, which improve the friction of the side wall of the rotating wheel 6.

[0025] The end of the linkage rod 3 near the turntable 7 is rounded. The rounded head reduces the friction between the linkage rod 3 and the wedge block 9. When the turntable 7 drives multiple wedge blocks 9 to rotate, the rounded head can slide out of the limiting groove 8, thereby achieving adjustment.

[0026] In use, the air blown into the ventilation duct 2 is guided to the surroundings by multiple air guide plates 1. When it is necessary to guide the air to a farther distance, the rotating wheel 6 is rotated. The rotating wheel 6 drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the rotating disk 7 to rotate, and the rotating disk 7 drives multiple wedge blocks 9 to rotate. The round head allows the linkage rod 3 to slide out of the limiting groove 8. When the linkage rod 3 moves away from the rotating disk 7, it can drive the multiple air guide plates 1 to rotate to a more horizontal state, thereby guiding the air in the ventilation duct 2 to a farther direction. The air guiding range of the air guide plate 1 can be adjusted according to the size of the indoor space, which is highly versatile and makes the air supply more uniform, thus improving the ventilation effect.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
