Description

Technical Field

[0001] This application relates to the field of new energy ship technology, and specifically discloses a closed engine room structure for a new energy ship. Background Technology

[0002] New energy ships refer to vessels that use non-traditional energy sources as their power source or auxiliary energy source. Currently, electric ships are the main type, relying entirely on the electrical energy stored in batteries to drive electric motors, thus enabling the ship to navigate. Pure electric ships have advantages such as no pollution, low noise, and ease of operation, making them suitable for inland waterways, lakes, and some short-distance maritime navigation scenarios, such as port operation vessels and inland river cruise ships.

[0003] Enclosed engine rooms offer significant advantages for new energy vessels. For example, they effectively prevent personnel from direct contact with electrical equipment and wiring, reducing the probability of electric shock. They also limit the spread of fire. Furthermore, enclosed engine rooms can be rationally laid out according to the characteristics and needs of electrical equipment, improving space utilization. Their relatively independent structure facilitates the maintenance and management of internal equipment. Therefore, enclosed engine rooms offer significant advantages in terms of safety, environmental adaptability, space utilization, and energy efficiency.

[0004] Enclosed engine room hull panels can provide some noise reduction. Some new energy ships fill the hull panels with sound-insulating materials to further improve the noise reduction effect inside the enclosed engine room. However, filling with sound-insulating materials not only thickens the hull panels and reduces the internal space of the engine room, but also leads to a decrease in the fire resistance of the enclosed engine room. Fire resistance is particularly important in new energy ships, and fireproof cloth and other structures are usually laid on top of the fireproof materials. Although some sound-insulating materials have certain fire resistance, their cost is high and their market competitiveness is poor. Furthermore, sound-insulating cotton does not provide good noise reduction at necessary ventilation openings, such as the ventilation openings of the air conditioning circulation system, and its noise reduction effect is poor for some low-frequency noises. In view of this, a new energy ship enclosed engine room structure is provided to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a closed engine room structure for new energy ships with high noise reduction performance.

[0006] To achieve the above objectives, the basic solution of this utility model provides a closed engine room structure for a new energy ship, comprising:

[0007] The cabin located on a new energy ship;

[0008] The active noise reduction assembly installed on the cabin body includes a detection cavity installed on the inner wall of the cabin body, an audio detection element installed on one side of the detection cavity, an audio element installed on one side of the detection cavity and facing the other side of the detection cavity, a circuit board that receives the audio detection element and controls the audio element, and a power supply element that supplies power to the audio detection element and the audio element.

[0009] Furthermore, the cabin includes a functional cabin located below the deck of the new energy ship and an active cabin located above the deck of the new energy ship. The audio detection element in the functional cabin is located on the side of the detection cavity closer to the interior of the functional cabin, and the audio detection element in the active cabin is located on the side of the detection cavity closer to the exterior of the active cabin.

[0010] Furthermore, the noise reduction component also includes an audio verification element located in the detection cavity, the audio element being situated between the audio detection element and the audio verification element.

[0011] Furthermore, the detection cavity is provided with several guide channels facing the audio detection element, and the audio element is located inside the guide channels.

[0012] Furthermore, the detection cavity is located inside the wall of the cabin, on the inner wall surface, on the outer wall surface, or at the ventilation opening of the cabin.

[0013] Furthermore, the detection cavity located at the ventilation opening of the cabin is also equipped with several hinges, and the orientations of adjacent hinges along the ventilation opening direction are staggered.

[0014] Furthermore, the side walls of the active cabin are all equipped with glass windows. The side walls of the active cabin are connected to the glass windows through wall panels. The connection between the wall panels and the glass windows forms an L-shaped fold and a filling gap is formed between them and the glass windows. The filling gap is filled with sealant.

[0015] The principle and effect of this solution are as follows:

[0016] Compared with existing technologies, this invention incorporates an active noise reduction component within the enclosed engine room of a new energy vessel. It utilizes audio detection elements to capture ambient noise and a circuit board to control the audio components to generate sound wave signals with opposite phase to the ambient noise, thus suppressing it. This is particularly effective against low-frequency noise. Furthermore, this invention combines active noise reduction with passive noise reduction through the engine room structure. While maintaining the enclosed performance of the new energy vessel, it improves the noise reduction effect inside the engine room, preventing the high noise levels generated by motors and generators during operation, which can damage the hearing of crew members due to prolonged exposure to high noise levels. This effectively reduces noise propagation, allowing crew members to work in a relatively quiet environment. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the accompanying drawings include: deck 1, active compartment 2, air conditioner 3, battery compartment 4, steering gear compartment 5, glass window 6, wall panel 7, sealant 8, detection chamber 9, hinge 10, audio detection element 11, audio verification element 12, audio element 13, guide block 14.

[0023] A closed engine room structure for a new energy ship, implementing, for example Figure 1 As shown: This includes the cabin installed on the new energy ship and the active noise reduction components installed on the cabin.

[0024] The hull includes a functional cabin located below deck 1 of the new energy ship and an activity cabin 2 located above deck 1 of the new energy ship. The functional cabin includes a battery compartment 4, a steering gear compartment 5, a sewage compartment, a fresh water compartment, etc., which are used to provide installation space for the necessary equipment for the operation of the new energy ship and to maintain the normal operation of the new energy ship. The activity cabin 2 includes a hall on deck 1, various relatively independent private rooms, etc., which are used for sightseeing and other activities.

[0025] In the enclosed engine room of the new energy ship, the ventilation inside each compartment relies on the air circulation of the air conditioner 3. The outdoor unit of the air conditioner 3 is located outside the compartment and exchanges air with the environment inside the compartment through the indoor unit of the air conditioner 3, ventilation ducts and other means.

[0026] like Figure 2As shown, the side walls of the active cabin 2 are equipped with glass windows 6. The glass windows 6 are made of tempered soundproof glass. The side walls of the active cabin 2 are connected to the glass windows 6 through wall panels 7. The connection between the wall panels 7 and the glass windows 6 forms an L-shaped fold and a filling gap is formed between them. The filling gap is filled with sealant 8. The L-shaped fold not only facilitates the installation and fixing of the glass windows 6, but also effectively improves the noise reduction performance at the connection between the wall panels 7 and the glass windows 6.

[0027] like Figure 3 As shown, the active noise cancellation assembly includes a detection cavity 9 located inside the cabin wall, on the inner wall surface, on the outer wall surface, or at the cabin vent, an audio detection element 11, an audio element 13, an audio verification element 12 disposed in the detection cavity 9, a circuit board for controlling the audio element 13, and a power supply element for supplying power to the audio detection element 11, the audio verification element 12, and the audio element 13.

[0028] When the detection cavity 9 is located inside the wall of the cabin, a sandwich layer is opened in the inner wall of the cabin to form the detection cavity 9; when the detection cavity 9 is located on the inner or outer wall surface of the cabin, a gypsum board is installed on the inner or outer wall surface of the cabin, and the gypsum board is hollow to form the detection cavity 9; when the detection cavity 9 is located at the vent of the cabin, the vent itself can be the detection cavity 9, and the detection cavity 9 is also provided with several hinges 10, and the orientation of adjacent hinges 10 along the direction of the vent is staggered.

[0029] Both the audio detection element 11 and the audio verification element 12 use microphones to capture ambient noise. The audio verification element 12 can also verify the noise suppression effect of the audio element 13. The audio element 13 uses a speaker to generate a sound wave signal that is out of phase with the ambient noise. The circuit board receives the data signals from the audio detection element 11 and the audio verification element 12 and controls the microphone to turn on. The power supply element uses a battery for power supply.

[0030] In the functional cabin, the audio detection element 11 is located on the side of the detection cavity 9 closer to the interior of the functional cabin, while the audio verification element 12 is located on the side of the detection cavity 9 away from the interior wall of the functional cabin. The audio element 13 is located between the audio detection element 11 and the audio verification element 12, thereby suppressing the noise generated in the functional cabin. In the activity cabin 2, the audio detection element 11 is located on the side of the detection cavity 9 closer to the exterior of the activity cabin 2, while the audio verification element 12 is located on the side of the detection cavity 9 closer to the interior of the activity cabin 2. The audio element 13 is located between the audio detection element 11 and the audio verification element 12, thereby suppressing the noise transmitted into the activity cabin 2.

[0031] The detection cavity 9 is provided with several guide blocks 14, and the guide blocks 14 are provided with guide channels facing the audio detection element 11. The audio element 13 is located inside the guide channel, thereby improving the suppression effect of the sound wave signal generated by the audio element 13 on environmental noise.

[0032] This embodiment incorporates an active noise reduction component within the enclosed engine room of a new energy vessel. An audio detection element 11 detects and captures ambient noise, while a circuit board controls an audio element 13 to generate a sound wave signal with the opposite phase to the ambient noise, thus suppressing it. This is particularly effective against low-frequency noise. Furthermore, this invention combines active noise reduction with passive noise reduction based on the engine room structure. While ensuring the enclosed performance of the new energy vessel, it improves the noise reduction effect inside the engine room, preventing the high noise levels generated by motors and generators during operation, which could damage the crew's hearing if exposed to high noise levels for extended periods. This effectively reduces noise propagation, allowing the crew to work in a relatively quiet environment.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
