It includes a housing, with a reversing mechanism between the inner walls of the housing. The reversing mechanism includes a fixed base, which is fixedly connected to the inner wall at one end of the housing. A support bracket is fixedly connected to the end of the fixed base.

Description

Technical Field

[0001] This utility model belongs to the field of marine ventilation technology, specifically a ventilation device suitable for marine power systems. Background Technology

[0002] Marine propulsion systems generate significant amounts of heat and harmful gases during operation. If these gases are not promptly removed, they can severely impact the ship's normal operation and the health of the crew. Therefore, effective ventilation equipment is essential for heat dissipation and the removal of harmful gases. Traditional ventilation systems typically employ a fixed suction direction with a limited suction range. This design presents several problems in practical applications. First, the internal structure of marine propulsion systems is complex, with varying distributions of heat and harmful gases in different areas. A fixed suction direction cannot be flexibly adjusted to meet the heat dissipation needs or the distribution of harmful gases in different parts of the propulsion system. Second, due to the limited suction range, traditional ventilation equipment cannot quickly and effectively ventilate, resulting in low ventilation efficiency and an inability to promptly remove heat and harmful gases, thus affecting the normal operation of the marine propulsion system and the working environment of the crew. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a ventilation device suitable for ship propulsion systems. It solves the problem that traditional ventilation devices usually adopt a fixed suction direction, have a limited suction range, and cannot quickly and effectively ventilate and exchange air, resulting in low ventilation efficiency and failure to remove heat and harmful gases in a timely manner, which in turn affects the normal operation of ship propulsion systems and the working environment of crew members.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device suitable for a marine power system, comprising a housing, a reversing mechanism provided between the inner walls of the housing, the reversing mechanism including a fixed seat, the fixed seat being fixedly connected to the inner wall at one end of the housing, a support bracket being fixedly connected to the end of the fixed seat, the support bracket being U-shaped, a connecting frame being rotatably connected between the inner walls of the support bracket near its end, a motor being rotatably connected between the inner walls of the connecting frame, a connecting shaft being rotatably connected to one end of the motor, the connecting shaft being bent and its other end being rotatably connected to the center position of the support bracket, a suction fan being installed at the other end of the motor, and several through slots being provided at both ends of the housing.

[0005] As a further embodiment of this utility model: one end of the housing is fixedly connected to a mounting bracket, and a sealing mechanism is provided between the inner walls of the mounting bracket. The sealing mechanism includes a first rotating rod, the two ends of the first rotating rod are rotatably connected to the top and bottom ends of the mounting bracket through bearings, a first sealing plate is fixedly connected to one side of the first rotating rod, and a first linkage rod is fixedly connected to the top end of the first rotating rod.

[0006] As a further embodiment of this utility model: a second rotating rod is rotatably connected to the outer wall of the first rotating rod, the second rotating rod and the first rotating rod are designed in a cross shape, a second sealing plate is fixedly connected to one side of the second rotating rod, and a second linkage rod is fixedly connected to the top of the second rotating rod, the second linkage rod and the first linkage rod are oriented in opposite directions.

[0007] As a further embodiment of this utility model: the top of the mounting bracket is provided with a driving mechanism, the driving mechanism includes a U-shaped bracket, and a U-shaped slider is slidably connected between the inner walls of the U-shaped bracket.

[0008] As a further embodiment of this utility model: two slots are respectively opened on opposite sides of the inner wall of the U-shaped slider, the first linkage rod and the second linkage rod are respectively engaged in the two slots, and a telescopic rod is fixedly installed at one end of the U-shaped bracket, the end of the telescopic rod is connected to one end of the U-shaped slider.

[0009] As a further embodiment of this utility model: a connecting plate is fixedly connected to the outer wall of the shell, and four connecting bolts are respectively provided at the four corners of the connecting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This ventilation equipment, applicable to marine propulsion systems, utilizes a reversing mechanism. When ventilation is required, the equipment activates, with a motor driving the suction fan within the connecting frame. Simultaneously, a bent connecting shaft at the other end propels the motor to rotate within the connecting frame, causing the connecting frame to rotate between the inner walls of the support bracket. This allows the suction fan to continuously change direction, flexibly adjusting the suction direction according to the heat dissipation needs of different parts of the marine propulsion system or the distribution of harmful gases. This expands the suction range, significantly improves ventilation efficiency, and enables rapid and effective ventilation, solving the problems of fixed suction range and low efficiency associated with traditional ventilation equipment.

[0012] 2. This ventilation equipment, applicable to marine propulsion systems, features a sealing mechanism. When ventilation is needed, the telescopic rod extends, pushing a U-shaped slider to slide within a U-shaped bracket. The U-shaped slider, through a slot, pulls the first and second linkage rods, causing the first and second rotating rods to open the first and second sealing plates to the sides, allowing airflow to pass smoothly. When sealing is needed, the telescopic rod shortens, pulling the U-shaped slider in the opposite direction. The first and second linkage rods then close the first and second sealing plates towards the center, tightly sealing the opening at the end of the casing and preventing airflow from entering. This method enables rapid switching between ventilation and sealing, avoiding unnecessary airflow leakage, further improving ventilation efficiency, and meeting the ventilation needs of marine propulsion systems under different operating conditions.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5As shown, this utility model provides a technical solution: a ventilation device suitable for a ship's power system, including a housing 1, a connecting plate 7 fixedly connected to the outer wall of the housing 1, and four connecting bolts 8 respectively provided at the four corners of the connecting plate 7. The connecting plate 7 is tightly connected to the installation structure of the ship's power system through the connecting bolts 8, which enhances the installation stability of the ventilation device. This multi-point fixing method can effectively disperse the various forces that the device is subjected to during operation, reduce the shaking and vibration of the device, and ensure the service life of the device.

[0021] A reversing mechanism 2 is provided between the inner walls of the housing 1. The reversing mechanism 2 includes a fixed base 201, which is fixedly connected to the inner wall at one end of the housing 1. A support bracket 202 is fixedly connected to the end of the fixed base 201. The support bracket 202 has a U-shaped design. A connecting frame 203 is rotatably connected between the inner walls of the support bracket 202 near its end. A motor 204 is rotatably connected between the inner walls of the connecting frame 203. A connecting shaft 205 is rotatably connected to one end of the motor 204. The connecting shaft 205 has a bent design, and its other end is rotatably connected to the center position of the support bracket 202. Through the cooperation between the connecting shaft 205, the support bracket 202, and the connecting frame 203, the motor 204... 04 Inside the connecting frame 203, the connecting shaft 205 is driven to rotate at one end of the fixed seat 201. Through the bending design of the connecting shaft 205, the connecting shaft 205 drives the motor 204 to rotate inside the connecting frame 203. At the same time, the connecting frame 203 rotates between the inner walls of the support bracket 202, so that the motor 204 can drive the suction fan 206 to flexibly change its orientation within a certain range. This design can expand the suction area and improve ventilation efficiency according to the heat dissipation requirements of different parts of the ship's power system or the distribution of harmful gases, and quickly and effectively carry out ventilation. The other end of the motor 204 is equipped with the suction fan 206. Several through slots 3 are opened at both ends of the housing 1.

[0022] A mounting bracket 4 is fixedly connected to one end of the housing 1. A sealing mechanism 5 is provided between the inner walls of the mounting bracket 4. The sealing mechanism 5 includes a first rotating rod 501. The two ends of the first rotating rod 501 are rotatably connected to the top and bottom ends of the mounting bracket 4 via bearings. A first sealing plate 502 is fixedly connected to one side of the first rotating rod 501. A first linkage rod 503 is fixedly connected to the top end of the first rotating rod 501. A second rotating rod 504 is rotatably connected to the outer wall of the first rotating rod 501. The second rotating rod 504 and the first rotating rod 501 are designed in a cross configuration. A second sealing plate 505 is fixedly connected to one side of the second rotating rod 504. A second linkage rod 506 is fixedly connected to the top end of the second rotating rod 504. The second linkage rod 506 and the first linkage rod 503 are connected in a cross configuration. With opposite orientations, the first rotating rod 501 and the second rotating rod 504 cooperate to drive the first sealing plate 502 and the second sealing plate 505 to rotate in opposite directions. This allows the first sealing plate 502 and the second sealing plate 505 to fit tightly against the opening at the end of the housing 1, achieving precise sealing control of the end of the housing 1. When complete sealing is required, the first sealing plate 502 and the second sealing plate 505 can open and fit tightly against the inner wall of the mounting bracket 4, thereby canceling the ventilation operation. When ventilation is required, the first sealing plate 502 and the second sealing plate 505 can open quickly to allow airflow to pass smoothly and ensure the normal operation of the ventilation function.

[0023] The top of the mounting bracket 4 is equipped with a drive mechanism 6. The drive mechanism 6 includes a U-shaped bracket 601, and a U-shaped slider 602 is slidably connected between the inner walls of the U-shaped bracket 601. Two slots 603 are respectively opened on opposite sides of the inner walls of the U-shaped slider 602. The first linkage rod 503 and the second linkage rod 506 are respectively engaged in the two slots 603. A telescopic rod 604 is fixedly installed at one end of the U-shaped bracket 601, and the end of the telescopic rod 604 is connected to one end of the U-shaped slider 602. Because of the drive mechanism 6, the drive mechanism... The telescopic rod 604 in section 6 extends and retracts, pushing the U-shaped slider 602 to slide within the U-shaped bracket 601. The U-shaped slider 602 pushes or pulls the first linkage rod 503 and the second linkage rod 506 through the slot 603, thereby achieving linkage control of the first rotating rod 501 and the second rotating rod 504. This causes the first sealing plate 502 and the second sealing plate 505 to open or close, thus switching between the sealed and ventilated states within the mounting bracket 4 and the housing 1. This simplifies the operation process and improves the efficiency of the equipment.

[0024] The working principle of this utility model is as follows: When the equipment is running, the motor 204 starts, and one end of the motor 204 drives the suction fan 206 to rotate, thereby generating airflow in the housing 1. This draws out the heat or harmful gases generated by the ship's power system through the through slots 3 at both ends of the housing 1. At the same time, the other end of the motor 204 drives the connecting shaft 205 to rotate. The connecting shaft 205 rotates within the support bracket 202 while the motor 204 rotates. The connecting shaft 205 drives the motor 204 to rotate within the connecting frame 203, and simultaneously drives the connecting frame 203 to rotate between the inner walls of the support bracket 202, continuously adjusting the orientation of the suction fan 206, thereby expanding the suction area of ​​the suction fan 206 and achieving the ventilation function. When adjusting the sealing degree at the end of the housing 1, the telescopic rod 604 in the drive mechanism 6 extends and retracts, pushing the U-shaped slider 602 to slide within the U-shaped bracket 601. As the U-shaped slider 602 slides, the first linkage rod 503 and the second linkage rod 504 extend and retract. The linkage rod 506 rotates the first rotating rod 501 and the second rotating rod 504 respectively. Since the first rotating rod 501 and the second rotating rod 504 are designed in a cross shape, they drive the first sealing plate 502 and the second sealing plate 505 to rotate respectively, and the rotation directions of the first sealing plate 502 and the second sealing plate 505 are opposite. When complete sealing is required, the telescopic rod 604 shortens, and the first linkage rod 503 and the second linkage rod 506 are pulled through the U-shaped slider 602 and the slot 603. The first linkage rod 503 and the second linkage rod 506 drive the first sealing plate 502 and the second sealing plate 505 to fit tightly against the opening at the end of the housing 1, thereby preventing airflow from entering the housing 1. When ventilation is required, the telescopic rod 604 extends, and the first linkage rod 503 and the second linkage rod 506 are pushed through the same steps, thereby allowing the first sealing plate 502 and the second sealing plate 505 to open, allowing airflow to pass smoothly, thus enabling the device to achieve ventilation and sealing control.
