Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a marine ventilator with a protective noise reduction structure. Background Art

[0002] In the shipbuilding industry, ventilators are an essential component of the ship's hull, providing fresh air to the cabin and ensuring a comfortable cabin environment. However, traditional ventilators often have many problems in practical applications.

[0003] In terms of protection, due to the complex and ever-changing navigation environment of ships, ventilators are easily damaged by external objects and lack effective protective measures. Regarding noise reduction, previous ventilators generated considerable noise during the ventilation process, seriously affecting the crew's work and quality of life. In the event of severe sea conditions and large amounts of seawater impacting the deck, conventional ventilators require crew members to manually close them on deck. This process not only makes it very easy for seawater to flow back into the cabin, causing serious damage to equipment and cargo, but also puts crew members on deck at great risk of being injured by waves. Utility Model Content

[0004] The purpose of the utility model is to provide a marine ventilator with a protective noise reduction structure to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution, which includes a vertical cylinder, a first sound insulation cotton is arranged in the vertical cylinder, a rainproof cap is arranged on the top of the vertical cylinder, a second sound insulation cotton is arranged in the rainproof cap, a relevant cover assembly is arranged between the rainproof cap and the vertical cylinder, and a protective assembly is arranged on the outside of the vertical cylinder and the rainproof cap.

[0006] As a preferred embodiment of the present invention, a plurality of first fixing members are provided on the outer wall of the vertical tube, and a support plate is provided on the inner wall of the vertical tube.

[0007] As a preferred embodiment of the present invention, several second fixing parts corresponding to the first fixing parts are provided on the inner wall of the rainproof hat, and the corresponding first fixing parts and second fixing parts are connected by a bolt group. An insect-proof net is also provided on the inner wall of the rainproof hat, and the insect-proof net is located above the several second fixing parts. A protective shell is provided on the top of the rainproof hat.

[0008] As a preferred embodiment of the present invention, the cover closing assembly includes a screw, which is movably arranged between the rainproof cap and the support plate through a pair of bearing seats, the top end of the screw is arranged on the transmission end of the motor, the motor is arranged in a protective shell, and a sealing cover plate is threaded on the screw, and the sealing cover plate is located above the vertical cylinder.

[0009] As a preferred embodiment of the present invention, several limiting grooves are provided on the outer wall of the rainproof cap, and the protective assembly includes several guardrails equidistantly arranged on the outside of the vertical cylinder and the rainproof cap, and the several guardrails are connected by several fixing rods, and a limiting plug is provided on the inner wall of each of the fixing rods, and the limiting plug is inserted in the limiting groove, and a welding plate is provided at the bottom of the fixing rod, and the welding plate is welded on the hull deck.

[0010] As a preferred embodiment of the present invention, a water immersion sensor is provided on one side of the top of the insect-proof net, and the water immersion sensor is connected to the motor control.

[0011] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0012] The utility model arranges a protective component on the outside of the vertical cylinder and the rain cap, including several protective rails arranged at equal intervals and fixing rods connecting the protective rails. The protective rails and the fixing rods can effectively prevent external objects from directly impacting and damaging the ventilator, providing physical protection for the ventilator. Especially during the navigation of the ship, various unexpected collisions or impacts of debris may be encountered. The protective component can greatly reduce the risk of damage to the ventilator, ensuring the normal operation and service life of the ventilator.

[0013] 2. The utility model arranges a first sound insulation cotton in the vertical cylinder and a second sound insulation cotton in the rain cap. The design of the double sound insulation cotton can significantly reduce the noise generated during ventilation. When the air flows in the ventilator, the sound insulation cotton can absorb and block the spread of noise, providing a relatively quiet environment in the cabin. This is of great significance for improving the work and life comfort of the crew, reducing the adverse effects of noise on the physical and mental health of the crew, and also helps to improve the crew's attention and efficiency at work.

[0014] 3. The utility model is provided with a water immersion sensor. When a large amount of seawater hits the deck, the water immersion sensor will detect the seawater and control the motor to rotate forward. The motor drives the screw to rotate forward, causing the sealing cover to descend until it is completely fitted on the top of the vertical cylinder, thereby closing the ventilator and effectively preventing seawater from flowing back into the hull cabin. This design can automatically activate the protection mechanism under severe sea conditions, promptly prevent the intrusion of seawater, protect the safety of equipment and cargo inside the hull, avoid damage to equipment and cargo and potential safety hazards caused by seawater backflow, enhance the safety and reliability of the ship in complex sea conditions, and at the same time avoid the need for crew members to run to the deck to manually close it, thereby increasing the safety of the crew.
