Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides a new energy ship battery compartment ventilation device, which can solve the problems that the existing battery compartment ventilation device in the related technology often adopts a single air inlet mode and an air exhaust mode, and the air inlet and the air outlet are not reasonable enough in layout, so that the air in the compartment flows smoothly, and ventilation dead angles exist.

Referring to fig. 1-3, the ventilation device for the battery compartment of the new energy ship comprises a compartment body 1, wherein a plurality of air supply assemblies 2 are arranged on one side of the compartment body 1, the plurality of air supply assemblies 2 are distributed along the length direction of the compartment body 1, the air supply assemblies 2 are used for supplying air into the compartment body 1, a plurality of exhaust fans 3 are arranged on the other side of the compartment body 1, the exhaust fans 3 are used for exhausting air in the compartment body 1, the air supply assemblies 2 comprise a shell 21 arranged on the compartment body 1, a first fan 22 is arranged in the shell 21, an air supply pipe 23 is communicated with the other end of the shell 21, and a filtering part 24 is arranged in the air supply pipe 23.

The cabin body 1 is used as a main body structure of the battery cabin, and provides a closed working environment for the battery pack. In order to maintain ventilation in the cabin, the device is provided with a plurality of air supply assemblies 2 along the length direction of the cabin body 1 at one side of the cabin body. These air supply assemblies 2 operate by means of an internal blower 22, drawing in external fresh air into the interior of the cabin 1. Meanwhile, in order to prevent the inhaled air from containing impurities or particles to damage the battery pack, a filter unit 24 is particularly provided inside the air supply pipe 23 to filter and purify the inhaled air.

On the other side of the cabin 1, the device is provided with a plurality of exhaust fans 3, i.e. exhaust fans 3. These fans 3 draw in cabin air to form an air flow path opposite to the air supply unit 2, thereby ensuring continuous and efficient circulation of cabin air. When the first fan 22 and the exhaust fan 3 work simultaneously, a stable airflow field is formed in the cabin body 1, heat and harmful gas generated by the battery pack are effectively taken away, and the safety and stability of the environment in the cabin are maintained.

Through setting up a plurality of air supply subassembly 2 and exhaust fan 3 along cabin body 1 length direction, this device has realized the evenly distributed and the high-efficient circulation of cabin air. The ventilation efficiency is improved, the air circulation in each corner of the cabin is ensured, the temperature of the battery pack is effectively reduced, and the service life of the battery is prolonged.

By adopting the redundant design of a plurality of air supply assemblies 2 and exhaust fans 3, the device can still keep certain ventilation capacity when a single assembly breaks down, thereby improving the reliability and stability of the whole ventilation system.

The impurities and the particulate matters in the air can be effectively filtered through the filtering part 24 arranged in the air supply pipe 23, and the impurities and the particulate matters are prevented from entering the cabin body 1 to damage the battery pack. This not only improves the cleanliness of the battery compartment, but also reduces the potential safety hazard caused by impurities.

The air supply assembly 2 and the exhaust fan 3 of the device are in modularized design, and are convenient to detach and replace independently. This greatly reduces maintenance costs and enables maintenance personnel to maintain and overhaul individual components without affecting the proper operation of the entire ventilation system.

Specifically, in this embodiment, a plurality of mounting frames 4 are disposed on the cabin 1, the housing 21 is disposed on the corresponding mounting frame 4, a protection net 7 is disposed inside the mounting frame 4, and one side of the housing 21, which is close to the mounting frame 4, is in an opening shape.

On one side of the cabin 1, a plurality of mounting frames 4 are arranged along the length direction of the cabin, and the mounting frames 4 not only provide stable mounting positions for the air supply assembly 2, but also further enhance the safety of the ventilation device through a protective screen 7 arranged inside the air supply assembly. The protection net 7 can effectively prevent external large sundries or animals from entering the air supply assembly 2, and damage to the fan I22 or the air supply pipe 23 is avoided.

The housing 21 of the air supply assembly 2 is mounted on the corresponding mounting frame 4 by bolts or other fastening means, and one side of the housing 21 adjacent to the mounting frame 4 is opened. This design allows the fan one 22 to smoothly suck outside air into the interior of the housing 21 and send it into the cabin 1 through the air supply duct 23. The filter portion 24 inside the air supply pipe 23 filters and purifies the sucked air, and ensures the quality of the air entering the cabin 1.

On the other side of the cabin 1, a plurality of exhaust fans 3, i.e. exhaust fans 3, are provided. The exhaust fans 3 draw in cabin air and form convection with the air supply assembly 2, so that continuous circulation of the cabin air is realized. When the first fan 22 and the exhaust fan 3 work simultaneously, a stable airflow field is formed inside the cabin body 1, and heat and harmful gas generated by the battery pack are effectively taken away.

Specifically, the air supply pipe 23 is in a zigzag shape, and a demister 5 is arranged in the middle of the air supply pipe 23.

The main function of the demister 5 is to remove moisture and micro-droplets from the air and prevent them from entering the interior of the cabin 1 and damaging the battery. The function of the mist eliminator 5 is particularly important, especially in humid or rainy environments. The solar cell battery can effectively prevent the problems of corrosion or short circuit of the battery pack and the like caused by overlarge air humidity, and the air supply pipe 23 adopts a fold line-shaped design, so that the filtered water mist can be prevented from flowing back.

In one embodiment, as shown in fig. 5, the filtering portion 24 includes a metal punched net 241 disposed at one end of the air supply pipe 23, a non-woven fabric filter screen 242 is disposed inside the air supply pipe 23, a mounting hole located above the non-woven fabric filter screen 242 is formed on the air supply pipe 23, and a sealing cover 243 is connected inside the mounting hole through a bolt.

The fan one 22 of the air supply assembly 2 sucks in outside air through the opening of the housing 21. The air first passes through the metal punched mesh one 241, which is a preliminary filtration barrier that can block larger particulate matter and impurities from entering the gas supply tube 23.

The air preliminarily filtered through the metal punched net one 241 continues to enter the inside of the air supply pipe 23. Inside the air supply pipe 23, a non-woven fabric filter screen 242 is provided, which is a finer filter screen, and can further filter out dust, fine particles and other impurities in the air, thereby ensuring the air quality.

The air filtering effect and the demisting capacity are further improved on the basis of the prior art, and a cleaner, safer and more reliable working environment is provided for the battery compartment of the new energy ship. Meanwhile, the device also has good maintenance convenience and air flow uniformity, and ensures long-term stable operation of the ventilation system.

In one embodiment, as shown in fig. 4, the exhaust fan 3 includes an exhaust pipe 31 and a housing 32 that are connected to each other, the housing 32 is disposed on the cabin 1, a side of the housing 32 connected to the cabin 1 is in an opening shape, a fan two 33 is disposed inside the housing 32, and the housing 32 is in communication with the exhaust pipe 31.

The housing 32 of the exhaust fan 3 is firmly attached to the cabin 1, and the side connected to the cabin 1 is opened. This ensures that the exhaust fan 3 can smoothly draw air from the interior of the cabin 1. The second fan 33 is disposed inside the housing 32, and when the second fan 33 is started, it generates a strong suction force to suck the air in the cabin into the housing 32.

The air sucked into the inside of the casing 32 is then guided to the exhaust duct 31. The exhaust duct 31 communicates with the inside of the housing 32 to form a smooth air passage. Thus, air can be smoothly discharged out of the cabin 1 along the exhaust pipe 31 by the second fan 33.

When the first fan 22 of the air supply assembly 2 and the second fan 33 of the exhaust fan 3 work simultaneously, they form a stable airflow field inside the cabin 1. The air supply assembly 2 continuously sends outside air into the cabin, and the exhaust fan 3 continuously draws out the air in the cabin to form convection. This convection helps to quickly carry away the heat and harmful gases generated by the battery pack, keeping the cabin environment clean and suitable.

Further, a filter screen 6 is disposed at the other end of the exhaust pipe 31.

In the new energy ship battery compartment ventilation device after further optimization, the filter screen 6 is additionally arranged at the other end of the exhaust pipe 31, so that the high-efficiency exhaust function of the original exhaust fan 3 is reserved, the exhaust pipe 31 and the inside of the shell 32 are protected, and the safety of the whole ventilation system is improved.
