Abstract

This invention discloses a fresh air circulation system for a marine monitoring buoy platform, comprising a mast mounted on the buoy platform body. The mast is equipped with an air inlet assembly for circulating air throughout the entire duct system. A first air duct is opened within the mast, connecting to a second air duct. The second air duct is detachably connected to multiple branch pipes, which are mounted on the ceiling of the control room within the buoy platform body. The other ends of the branch pipes connect to various compartments, each compartment having an exhaust duct with an exhaust outlet assembly installed within it. This invention solves the problem that while large, automated observation buoy platforms require ventilation equipment in each compartment, air inlets installed externally to the buoy platform may be affected by waves, leading to water ingress and damage to the entire fresh air circulation system.

Description

Technical Field

[0001] This invention relates to a fresh air circulation system for marine monitoring buoy platforms. Background Technology

[0002] Ocean buoys are automatic marine hydrological, water quality, and meteorological observation stations mainly composed of observation buoys anchored at sea. They can collect marine hydrological, water quality, and meteorological data required for marine scientific research, offshore oil (gas) development, port construction, and national defense construction on a long-term and continuous basis, especially data on severe weather and sea conditions that are difficult for survey vessels to collect.

[0003] Large automated observation buoy platforms are typically equipped with numerous scientific instruments and communication devices. To ensure the proper functioning of these instruments and devices, the buoy platform has a fuel chamber for autonomous power generation. Researchers also periodically enter the buoy platform to collect data and maintain equipment. Therefore, each compartment of a large automated observation buoy platform should be equipped with ventilation systems. However, air inlets installed on the outside of the buoy platform may be affected by waves, causing water to enter and damage the entire fresh air circulation system. Summary of the Invention

The second air duct is detachably connected to multiple branch pipes, and the second air duct is connected to the multiple branch pipes. The second air duct is installed on the ceiling of the control room in the buoy platform body. A fan is installed inside the second air duct. The other ends of the multiple branch pipes are connected to various compartments. Each compartment is equipped with an air outlet duct, and each air outlet duct is equipped with an air outlet assembly for exhausting air.

[0006] Preferably, the air inlet assembly includes an air inlet duct, a vibration structure, a mounting bracket, a motor, a threaded rod, a first support plate, two second support plates, two rain shields, four limiting frames, and two first dust filter plates. The air inlet duct is located on the upper surface of the mast and is connected to the first air duct. The mounting bracket is located inside the mast, and the mounting bracket has a fixed end for the motor. The output end of the motor is connected to one end of the threaded rod, and the other end of the threaded rod is connected to the inner wall of the bearing. The outer wall of the bearing is installed in a first mounting groove on the top surface of the air inlet duct. Neither end of the threaded rod has external threads, and the threaded rod is threaded with the... A first support plate, with a second support plate connected to each end of the first support plate, and a rain shield connected to the other end of each of the two second support plates. A second mounting groove is provided on the inner bottom surface of the air inlet duct, and the two second support plates are located in the second mounting groove. Two through movable grooves are mirror-imagely provided on the air inlet duct, and the two rain shields are slidably connected to the corresponding movable grooves. Two limiting frames are provided in each rain shield, and a first dust filter plate is placed in the two limiting frames. A first soft pad is provided at the edges on both sides of the first dust filter plate, and the first soft pad is in contact with the corresponding limiting frame. The vibration structure is provided on the upper surface of the air inlet duct.

[0007] Preferably, the vibration structure includes a limiting block, a force-bearing plate, two third support plates, two cylindrical rods, and two springs. Two limiting grooves are formed on the upper surface of the air inlet duct, and a limiting block is movably connected to each limiting groove. The force-bearing plate is connected to the upper surface of the two limiting blocks. A cylindrical rod is connected to each side of the force-bearing plate. Two third support plates are mirror-connected to the upper surface of the air inlet duct. Each cylindrical rod passes through its corresponding third support plate. Two springs are also connected to both sides of the force-bearing plate, and the other ends of the two springs are connected to the third support plates. The two springs are sleeved on their corresponding cylindrical rods.

[0008] Preferably, the air outlet assembly includes an exhaust fan, a one-way valve, a rain cover, and a second dust filter plate. The bottom of the air outlet duct is provided with the second dust filter plate. The exhaust fan is installed inside the air outlet duct. The one-way valve is also installed inside the air outlet duct. The one-way valve is located above the exhaust fan. The rain cover is connected to the upper surface of the air outlet duct. A water guide hole is provided on the air outlet duct.

[0009] Preferably, each of the branch pipes is provided with an air outlet.

By combining the mast and the air inlet assembly, the height of the mast can be utilized to effectively prevent waves from entering the air inlet assembly and effectively protect the entire fresh air circulation system.

[0014] Affected by the wind, the force plate will move along the direction of the limiting groove. At this time, the cylindrical rod on one side of the force plate will hit the corresponding first dust filter plate. Since the sea breeze is intermittent, when the wind force on the force plate suddenly disappears, under the action of the two spring forces, the cylindrical rod on the other side of the force plate will hit the corresponding first dust filter plate. Under the combined influence of rain and impact, the dust accumulated on the two first dust filter plates will be removed, preventing daily dust from accumulating on the first dust filter plates and affecting the working efficiency of the fresh air circulation system.

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] like Figure 1-7 As shown, a fresh air circulation system for a marine monitoring buoy platform includes a mast 1, a first air duct 4, a second air duct 5, a fan 9, an air outlet duct 7, and an air outlet assembly 8.

[0026] Specifically, the mast 1 is installed on the buoy platform body 2. The mast 1 is equipped with an air inlet assembly 3 for circulating air throughout the entire air duct. A first air duct 4 is opened inside the mast 1. Combining the mast 1 and the air inlet assembly 3 not only saves floor space but also effectively prevents waves from entering the air inlet assembly 3 by utilizing the characteristics of the mast 1. The first air duct 4 is connected to a second air duct 5. The second air duct 5 is detachably connected to multiple branch pipes 6, which facilitates subsequent maintenance and repair of the second air duct 5 and the multiple branch pipes 6. The second air duct 5 is connected to the multiple branch pipes 6 and is installed on the ceiling of the control room in the buoy platform body 2. A fan 9 is installed inside the second air duct 5. The other end of the multiple branch pipes 6 is connected to each compartment. Each compartment is equipped with an air outlet duct 7. Setting up an air outlet duct in each compartment can greatly reduce the internal pipe layout and accelerate the circulation of fresh air inside the buoy platform. An air outlet assembly 8 for exhaust is installed in each air outlet duct 7.

[0027] Specifically, the air inlet assembly 3 includes an air inlet duct 31, a vibration structure 32, a mounting bracket 33, a motor 34, a threaded rod 35, a first support plate 36, two second support plates 37, two rain shields 38, four limiting frames 39, and two first dust filter plates 310. The upper surface of the mast 1 is provided with the air inlet duct 31, which is connected to the first air duct 4. The mast 1 contains the mounting bracket 33, which has a fixed end for the motor 34. The output end of the motor 34 is connected to one end of the threaded rod 35, and the other end of the threaded rod 35 is connected to the inner wall of the bearing. The outer wall of the bearing is installed in the first mounting groove opened on the top surface of the air inlet duct 31. Neither end of the threaded rod 35 has external threads. A first support plate 36 is threadedly connected to the air inlet duct 31. A second support plate 37 is connected to each end of the first support plate 36. A rain shield 38 is connected to the other end of each of the two second support plates 37. A second mounting groove is provided on the inner bottom surface of the air inlet duct 31. The two second support plates 37 are located in the second mounting groove. Two through movable grooves are mirrored on the air inlet duct 31. The two rain shields 38 are slidably connected to the corresponding movable grooves. Two limiting frames 39 are provided in each rain shield 38. A first dust filter plate 310 is placed in the two limiting frames 39. A first soft pad is provided on the edges of both sides of the first dust filter plate 310. The first soft pad is in contact with the corresponding limiting frame 39. A vibration structure 32 is provided on the upper surface of the air inlet duct 31.

[0028] Specifically, the vibration structure 32 includes a limiting block 321, a force-bearing plate 322, two third support plates 323, two cylindrical rods 324, and two springs 325. The upper surface of the air inlet duct 31 has two limiting grooves, and a limiting block 321 is movably connected in each limiting groove. The upper surface of the two limiting blocks 321 is connected to the force-bearing plate 322. A cylindrical rod 324 is connected to each side of the force-bearing plate 322. The upper surface of the air inlet duct 31 is mirror-connected to the two third support plates 323. Each cylindrical rod 324 passes through the corresponding third support plate 323. Two springs 325 are also connected to both sides of the force-bearing plate 322. The other end of the two springs 325 is connected to the third support plate 323. The two springs 325 are sleeved on the corresponding cylindrical rods 324.

[0029] Specifically, the air outlet assembly 8 includes an exhaust fan 81, a one-way valve 82, a rain cover 83, and a second dust filter plate 84. The bottom of the air outlet duct 7 is provided with the second dust filter plate 84. An exhaust fan 81 is installed inside the air outlet duct 7. A one-way valve 82 is also installed inside the air outlet duct 7. The one-way valve 82 can effectively prevent external seawater from entering each compartment through the air outlet duct 7, preventing water from entering each compartment and causing damage to the internal equipment. The one-way valve 82 is located above the exhaust fan 81. A rain cover 83 is connected to the upper surface of the air outlet duct 7. Water guide holes 85 are opened on the air outlet duct 7. Multiple water guide holes 85 are located above the one-way valve 82. The water guide holes 85 can effectively prevent seawater from accumulating inside the air outlet duct 7.

[0030] Specifically, each branch pipe 6 is equipped with an air outlet; a second soft pad is provided in each of the two movable slots, and the second soft pad is in close contact with the rain shield 38. The second soft pad can effectively prevent rainwater from seeping in from the gap between the rain shield 38 and the movable slot. The rain shield 38 can effectively block rainwater from entering the air inlet pipe 31; the stress plate 322, the two third support plates 323, the cylindrical rod 324, the air inlet pipe 31 and the first dust filter plate 310 are all made of stainless steel. Stainless steel has good corrosion resistance and can greatly extend the service life of this device.

[0031] Specifically, the fan 9, motor 34 and exhaust fan 81 are all electrically connected to the control equipment in the control room, and the fan 9, motor 34 and exhaust fan 81 are powered by the diesel generator in the energy room.

[0032] Working principle: Under the action of the fan 9, the outside air enters the first air duct 4 from both ends of the air inlet duct 31, and then enters each branch duct 6 through the second air duct 5. The air is then delivered to each compartment through the air outlet on the branch duct 6. The air in each compartment is discharged by the exhaust fan 81 in each air outlet duct 7.

[0033] When it rains, to protect the safety of the entire fresh air circulation system, the fan 9 and all exhaust fans 81 are turned off. At this time, the motor 34 is started, and the motor 34 drives the threaded rod 35 to rotate. According to the principle of screw transmission, the first support plate 36 drives the two second support plates 37 and the two rain shields 38 to move upward along the direction of the threaded rod 35 until the two second support plates 37 are completely in contact with the inner top surface of the air inlet duct 31. At this time, the two first dust filter plates 310 are completely removed from the air inlet duct 31, and the rain shields 38 completely block both ends of the air inlet duct 31. Rain at sea is often accompanied by strong winds. Affected by the wind force, the force plate 322 will move along the direction of the limiting groove. When movement occurs, the cylindrical rod 324 on one side of the force plate 322 will strike the corresponding first dust filter plate 310. Due to the intermittent sea breeze, when the wind force on the force plate 322 suddenly disappears, under the action of the elastic force of the two springs 325, the cylindrical rod 324 on the other side of the force plate 322 will strike the corresponding first dust filter plate 310. Under the combined influence of rain and impact, the dust accumulated on the two first dust filter plates 310 will be removed. When the weather clears up, the motor 34 reverses and drives the two rain shields 38 back to the initial position. At this time, the fan 9 and each exhaust fan 81 start working again to maintain air circulation in the buoy platform body 2.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
