Description

Technical Field

[0001] This utility model relates to the field of marine ventilation duct technology, and in particular to a marine ventilation duct. Background Technology

[0002] During ship operation, cabin ventilation is a crucial aspect of ensuring the health of personnel and the normal operation of equipment. Traditional marine ventilation ducts are mostly fixed structures or only have simple opening and closing functions, making it difficult to flexibly adjust the ventilation direction and volume according to wind direction, weather, and cabin requirements. Furthermore, in the complex environment at sea, ventilation ducts are susceptible to wind and rain intrusion, leading to water ingress or reduced ventilation efficiency. In addition, some ventilation devices are inconvenient to adjust and operate, have poor sealing, and are prone to failure due to corrosion or structural loosening over long-term use, failing to meet the comprehensive requirements of ships for the safety, reliability, and ease of operation of ventilation systems. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a marine ventilation duct to solve the problem of inconvenient ventilation adjustment in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A marine ventilation duct includes a fixed base, a ventilation cap mounted on the fixed base, and a ventilation pipe mounted at the lower end of the fixed base, wherein a ventilation assembly is disposed in the ventilation pipe; a ventilation plate is disposed on the fixed base, an adjusting cover is disposed on the ventilation cap, and a ventilation adjusting device is disposed between the ventilation plate and the adjusting cover; the ventilation adjusting device includes a rotating shaft passing through the adjusting cover and the ventilation plate, an adjusting knob disposed at the top end of the rotating shaft, a lifting assembly disposed on the rotating shaft, and a retaining plate disposed on the ventilation plate.

[0006] To achieve the above technical solution, when ventilation needs adjustment, rotating the adjustment knob drives the rotating shaft to rotate. The shaft passes through the adjustment cover and the ventilation plate, and the lifting component on it moves synchronously with the shaft, thereby driving the adjustment cover to rotate relative to the ventilation plate. During this process, the rotation of the shaft, through the cooperation of the lifting component and the locking plate, realizes the axial movement of the adjustment cover during rotation, thereby adjusting the opening and closing state of the ventilation opening. The ventilation component works collaboratively within the ventilation duct to assist in the intake or exhaust of airflow, achieving the adjustment of the ventilation state. By setting a ventilation adjustment device consisting of a rotating shaft, adjustment knob, lifting component, and locking plate between the ventilation plate and the adjustment cover, the rotation and lifting of the adjustment cover are linked and controlled, enabling flexible adjustment of the ventilation direction and control of the ventilation volume.

[0007] In one embodiment of the present invention, the lifting assembly includes a spline shaft that engages with the rotating shaft spline, a bushing sleeve fitted on the spline shaft, a lifting plate fixed in the circumferential direction of the bushing sleeve, and a plurality of connecting rods connecting the lifting plate and the adjusting cover plate; the rotation of the rotating shaft can drive the spline shaft and the bushing sleeve to rotate synchronously, and allow the bushing sleeve to slide axially relative to the spline shaft.

[0008] To achieve the above technical solution, when the adjustment knob is rotated, the rotating shaft rotates accordingly. Since the rotating shaft and the splined shaft are splined, torque is transmitted to the splined shaft, thereby driving the bushing and the lifting plate fixed to its circumference to rotate synchronously. The lifting plate is connected to the adjustment cover plate through several connecting rods, so the rotation of the lifting plate causes the adjustment cover plate to rotate around the central axis, realizing the adjustment of the ventilation direction. At the same time, during the rotation, the bushing can slide along the splined shaft axis, causing the lifting plate to move up and down while rotating, which in turn drives the adjustment cover plate to rise and fall through the connecting rods, completing the opening and closing action.

[0009] In one embodiment of this utility model, the lifting plate is folded downward to form an adjusting plate, and the clamping plate is folded upward to form a supporting plate; rotating the adjusting knob can simultaneously rotate the rotating shaft and drive the lifting plate and the adjusting cover plate to rotate, while also allowing the adjusting plate to abut against the supporting plate.

[0010] To achieve the above technical solution, when the adjustment knob is turned, the rotating shaft drives the spline shaft and bushing to rotate, thereby causing the lifting plate and the connecting rod connected to it to rotate synchronously, realizing the rotational adjustment of the adjustment cover. As the lifting plate rotates, its downward-folding adjustment plate also rotates, and during the movement, it comes into contact with and interacts with the upward-folding support plate of the clamping plate. This contact relationship restricts the axial position of the lifting plate, which in turn pushes the adjustment cover towards the ventilation plate through the connecting rod, realizing the pressing or opening action of the cover.

[0011] In one embodiment of the present invention, the ventilation cap includes a base plate, a through hole extending vertically, a plurality of ventilation openings formed around the circumference of the ventilation cap, and a waterproof ring located on the base plate on the inner side of the ventilation openings.

[0012] To achieve the above technical solution, when the adjusting cover is opened, air enters the interior of the ventilation cap through the circumferentially arranged vents and flows to the lower ventilation pipe through the through holes. The waterproof ring inside the vent is located on the base plate and forms a close or gap fit with the lower surface of the cover when the adjusting cover is closed. When rainwater enters the vent from the side, the waterproof ring can prevent some water droplets from flowing directly into the through holes and guide the water flow to be discharged along the outside of the base plate.

[0013] In one embodiment of the present invention, the ventilation assembly includes a support seat disposed in the inner wall of the ventilation duct, a motor disposed on the support seat, and a plurality of fan blades disposed on the output shaft of the motor.

[0014] To achieve the above technical solution, the motor in the ventilation assembly is mounted on a support on the inner wall of the ventilation duct. After the motor starts, it drives the fan blades on the output shaft to rotate. The rotation of the fan blades generates airflow power, drawing outside air into the cabin or expelling air from the cabin. Driven by the motor, the fan blades form a stable airflow channel, which, together with the guiding effect of the ventilation duct, achieves forced ventilation and enhances air circulation efficiency.

[0015] As described above, the marine ventilation duct of this utility model has the following beneficial effects: By setting up a ventilation adjustment device, this utility model achieves coordinated control of the rotation and lifting of the adjustment cover, enabling flexible adjustment of the ventilation direction and control of the opening and closing of the ventilation openings, thus improving ventilation adaptability and ease of use. The waterproof ring structure of the ventilation cap effectively prevents rainwater from entering from the side, enhancing rainproof performance; the motor and fan blades of the ventilation component work together to achieve forced ventilation, improving air circulation efficiency. The overall structural design is reasonable, integrating natural and forced ventilation, wind direction adjustment, and sealing and rainproof functions, making it suitable for complex and changing ship operating environments, and possessing good practicality and reliability.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please see Figure 1 Figure 3 This utility model provides a marine ventilation duct, including a fixed base 1, a ventilation cap 2 disposed on the fixed base 1, and a ventilation pipe 3 disposed at the lower end of the fixed base 1, wherein a ventilation component is disposed in the ventilation pipe 3; a ventilation plate 4 is disposed on the fixed base 1, an adjusting cover plate 5 is disposed on the ventilation cap 2, and a ventilation adjusting device is disposed between the ventilation plate 4 and the adjusting cover plate 5; the ventilation adjusting device includes a rotating shaft 6 passing through the adjusting cover plate 5 and the ventilation plate 4, an adjusting knob 7 disposed at the top end of the rotating shaft 6, a lifting component disposed on the rotating shaft 6, and a retaining plate 8 disposed on the ventilation plate 4.

[0024] When ventilation needs adjustment, rotating the adjustment knob 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 passes through the adjustment cover plate 5 and the ventilation plate 4. The lifting component on it moves synchronously with the rotating shaft 6, thereby driving the adjustment cover plate 5 to rotate relative to the ventilation plate 4. During this process, the rotation of the rotating shaft 6, through the cooperation of the lifting component and the locking plate 8, realizes the axial movement of the adjustment cover plate 5 during rotation, thereby adjusting the opening and closing state of the ventilation opening 15. The ventilation component works in concert within the ventilation pipe 3 to assist in the intake or exhaust of airflow, thereby achieving the adjustment of the ventilation state. By setting a ventilation adjustment device consisting of the rotating shaft 6, the adjustment knob 7, the lifting component, and the locking plate 8 between the ventilation plate 4 and the adjustment cover plate 5, the rotation and lifting of the adjustment cover plate 5 are linked and controlled, allowing for flexible adjustment of the ventilation direction and control of the ventilation volume.

[0025] The lifting assembly includes a splined shaft 9 that splines in mate with the rotating shaft 6, a bushing 10 sleeved on the splined shaft 9, a lifting plate 11 fixed in the circumferential direction of the bushing 10, and a plurality of connecting rods 12 connected to the lifting plate 11 and the adjusting cover plate 5; the rotation of the rotating shaft 6 can drive the splined shaft 9 and the bushing 10 to rotate synchronously, and allow the bushing 10 to slide axially relative to the splined shaft 9.

[0026] When the adjustment knob 7 is rotated, the rotating shaft 6 rotates accordingly. Since the rotating shaft 6 and the splined shaft 9 are splined, torque is transmitted to the splined shaft 9, thereby driving the bushing 10 and the lifting plate 11 fixed around it to rotate synchronously. The lifting plate 11 is connected to the adjusting cover plate 5 through several connecting rods 12. Therefore, the rotation of the lifting plate 11 drives the adjusting cover plate 5 to rotate around the central axis, realizing the adjustment of the ventilation direction. At the same time, during the rotation, the bushing 10 can slide along the axial direction of the splined shaft 9, so that the lifting plate 11 moves up and down while rotating, and then drives the adjusting cover plate 5 to rise and fall through the connecting rods 12, completing the opening and closing action.

[0027] The lifting plate 11 is folded downward to form an adjusting plate 111, and the clamping plate 8 is folded upward to form a supporting plate 81. Rotating the adjusting knob 7 can simultaneously rotate the rotating shaft 6 and drive the lifting plate 11 and the adjusting cover plate 5 to rotate, while also allowing the adjusting plate 111 to abut against the supporting plate 81.

[0028] When the adjustment knob 7 is turned, the rotating shaft 6 drives the spline shaft 9 and the bushing 10 to rotate, thereby causing the lifting plate 11 and the connecting rod 12 connected to it to rotate synchronously, realizing the rotational adjustment of the adjusting cover plate 5. As the lifting plate 11 rotates, its downward-folding adjusting plate 111 rotates accordingly, and during the movement, it comes into contact with and interacts with the upward-folding support plate 81 of the clamping plate 8. This abutment relationship restricts the axial position of the lifting plate 11, which in turn pushes the adjusting cover plate 5 towards the ventilation plate 4 through the connecting rod 12, realizing the pressing or opening action of the cover plate.

[0029] The ventilation cap 2 includes a base plate 13, a through hole 14 extending vertically, and several ventilation openings 15 circumferentially arranged on the ventilation cap 2. A waterproof ring 16 is located on the base plate 13 and situated inside each ventilation opening 15. When the adjusting cover 5 is opened, air enters the ventilation cap 2 through the circumferentially arranged ventilation openings 15 and flows through the through hole 14 to the lower ventilation pipe 3. The waterproof ring 16 on the inner side of the ventilation opening 15 is located on the base plate 13 and forms a close or gap fit with the lower surface of the cover plate when the adjusting cover 5 is closed. When rainwater enters the ventilation opening 15 from the side, the waterproof ring 16 can prevent some water droplets from flowing directly into the through hole 14 and guide the water flow out along the outer side of the base plate 13.

[0030] The ventilation assembly includes a support base 17 disposed within the inner wall of the ventilation duct 3, a motor 18 disposed on the support base 17, and a plurality of fan blades 19 disposed on the output shaft of the motor 18. The motor 18 is mounted on the support base 17 within the inner wall of the ventilation duct 3. Upon startup, the motor 18 drives the fan blades 19 on the output shaft to rotate. The rotation of the fan blades 19 generates airflow power, drawing outside air into the cabin or expelling air from the cabin. Driven by the motor 18, the fan blades 19 form a stable airflow channel, which, combined with the guiding effect of the ventilation duct 3, achieves forced ventilation and enhances air circulation efficiency.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
