Description
Technical Field
[0001] This utility model relates to the field of integrated air duct technology, specifically to an integrated air duct for a prefabricated energy storage battery compartment. Background Technology
[0002] Prefabricated energy storage battery compartments are highly integrated modular energy storage systems. Their core is the pre-installation and commissioning of electrochemical batteries (such as lithium-ion batteries), battery management systems (BMS), power converters (PCS), temperature control systems, fire protection systems, and necessary auxiliary facilities within a standardized enclosure (compartment) in a factory. Upon arrival at the site, only simple grid connection and basic commissioning are required for operation, significantly shortening the construction cycle. They are primarily used for smoothing renewable energy (such as photovoltaic and wind power) power generation output, grid peak shaving and frequency regulation, and as backup power for industrial and commercial applications. The prefabricated energy storage battery compartment requires the installation of integrated air ducts, typically installed along the airflow path inside the compartment, to efficiently remove the heat generated during battery operation, ensuring all batteries operate at suitable temperatures.
[0003] However, existing integrated air ducts have areas that are difficult to cover during use, leading to significant temperature differences between battery modules in some areas and potentially causing excessively high temperatures in others. Therefore, those skilled in the art have provided an integrated air duct for a prefabricated energy storage battery compartment to solve the problems mentioned in the background. Utility Model Content
[0004] The purpose of this invention is to provide an integrated air duct for a prefabricated energy storage battery compartment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An integrated air duct for a prefabricated energy storage battery compartment includes a cooling fan, an air inlet duct connected to one side of the cooling fan, an air inlet dustproof net on the outside of the cooling fan, multiple guide ducts installed on the top of the air inlet duct, an installation bracket fixed on the outside of the air inlet duct, an auxiliary cooling mechanism installed on the top of the air inlet duct, an assembly mechanism on the outside of the auxiliary cooling mechanism, and dustproof nets on the outer wall and top of the guide ducts. The auxiliary cooling mechanism includes a mounting shell, a fixed bracket fixed to one inner wall of the mounting shell, a servo motor fixed to one side of the fixed bracket, a cast iron rotating disk fixed to one end of the output shaft of the servo motor, a wear-resistant rod installed on the outer side of the cast iron rotating disk, two limiting rods fixed to the inner bottom wall of the mounting shell, wear-resistant mounting sleeves movably sleeved on the outer side of the limiting rods, a lifting bracket fixed between the corresponding surfaces of the two wear-resistant mounting sleeves, an auxiliary cooling fan fixed to one side of the lifting bracket, a filter screen provided on the outer wall of the mounting shell, and a limiting sleeve fixed to the outer side of the wear-resistant mounting sleeve.
[0006] As a further improvement of this utility model: the limiting sleeve is movably sleeved on the outside of the wear-resistant rod, and the inside of the limiting sleeve is provided with a limiting through groove that matches the size of the wear-resistant rod.
[0007] As a further improvement of this utility model, the wear-resistant mounting sleeve has a guide hole inside, the size of which is adapted to the size of the limiting rod.
[0008] As a further embodiment of this utility model: the assembly mechanism includes a guide plate, the top of the guide plate is slidably connected to a guide sliding block via a slide groove, a limit mounting sleeve is fixed on one side of the guide sliding block, a fixing pad is fixed on the outer side of the mounting housing, an assembly set is fixed on the top of the fixing pad, a galvanized threaded rod is installed on the top of the fixing pad, and a galvanized nut is threadedly connected to the outer side of the galvanized threaded rod.
[0009] As a further improvement of this utility model, a limiting groove is provided inside the limiting mounting sleeve, and the size of the limiting groove is adapted to the size of the galvanized threaded rod.
[0010] As a further improvement of this utility model: the guide plate and the air inlet duct are fixedly connected, and the bottom surface of the limiting mounting sleeve is in contact with the top surface of the fixing pad.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This device is equipped with an auxiliary cooling mechanism, which allows the auxiliary cooling fan to move up and down simultaneously. After the auxiliary cooling fan is started, it can blow the cold air from the side of the air duct to different positions, so that the airflow reaches corners that are difficult to cover, significantly reducing the temperature difference between battery modules in different areas of the cabin. Through the dynamically adjustable air supply method, the purpose of uniform air supply is achieved, which helps to ensure good air supply effect in the prefabricated energy storage battery cabin. 2. With the assembly mechanism, when the housing is installed at the top of the air inlet duct, the limiting installation sleeve passes through the housing and is movably sleeved on the outside of the galvanized threaded rod. After the galvanized nut and the galvanized threaded rod are threaded together, the bottom surface of the galvanized nut presses against the limiting installation sleeve, which facilitates the positioning and fixing of the housing, making the installation and subsequent maintenance and repair operations simple.

The auxiliary cooling mechanism 6 includes a mounting shell 61. A fixing bracket 62 is fixed to the inner wall of one side of the mounting shell 61. A servo motor 63 is fixed to one side of the fixing bracket 62. A cast iron rotating disk 64 is fixed to one end of the output shaft of the servo motor 63. A wear-resistant rod 65 is installed on the outer side of the cast iron rotating disk 64. Two limiting rods 66 are fixed to the inner bottom wall of the mounting shell 61. A wear-resistant mounting sleeve 67 is movably sleeved on the outer side of the limiting rod 66. A lifting bracket 68 is fixed between the corresponding surfaces of the two wear-resistant mounting sleeves 67. An auxiliary cooling fan 69 is fixed to one side of the lifting bracket 68. A filter screen 610 is provided on the outer wall of the mounting shell 61. A limiting sleeve 611 is fixed to the outer side of the wear-resistant mounting sleeve 67. The limiting sleeve 611 is movably sleeved on the outer side of the wear-resistant rod 65. A limiting through groove adapted to the size of the wear-resistant rod 65 is opened inside the limiting sleeve 611. A guide hole is opened inside the wear-resistant mounting sleeve 67. The size of the guide hole is adapted to the size of the limiting rod 66.
[0016] In one embodiment of this utility model, the assembly mechanism 8 includes a guide plate 81. A guide sliding block 82 is slidably connected to the top of the guide plate 81 via a sliding groove. A limiting mounting sleeve 83 is fixed to one side of the guide sliding block 82. A fixing pad 84 is fixed to the outside of the mounting housing 61. An assembly piece 85 is fixed to the top of the fixing pad 84. A galvanized threaded rod 86 is installed on the top of the fixing pad 84. A galvanized nut 87 is threadedly connected to the outside of the galvanized threaded rod 86.

The guide plate 81 and the air inlet duct 2 are fixedly connected. The bottom surface of the limiting mounting sleeve 83 is in contact with the top surface of the fixing pad 84.
[0017] The working principle of this utility model is as follows: This device is equipped with an auxiliary cooling mechanism 6. The device is installed on the inner bottom wall of the prefabricated energy storage battery compartment. After the air inlet duct 2 is activated, cold air is delivered to different positions within the prefabricated energy storage battery compartment via the dustproof nets 7 on the top and sides of the guide duct 3. Subsequently, the servo motor 63 inside the mounting housing 61 is activated, causing the output shaft of the servo motor 63 to drive the cast iron rotating disk 64 to rotate. The cast iron rotating disk 64, through the wear-resistant rod 65, drives the limiting sleeve 611 to move up and down reciprocally. This allows the limiting sleeve 611 to simultaneously move the wear-resistant mounting sleeve 67 and the lifting bracket 68, enabling the auxiliary cooling fan 69 to move up and down simultaneously. After the auxiliary cooling fan 69 is activated, it can blow the cold air from the sides of the guide duct 3 to different positions, allowing the airflow to reach hard-to-reach corners and significantly reducing the temperature of the compartment. The temperature difference between battery modules in different areas is mitigated by a dynamically adjustable air supply method, achieving uniform airflow and ensuring good airflow performance in the prefabricated energy storage battery compartment. With the assembly mechanism 8, when the mounting housing 61 is installed on top of the air inlet duct 2, after placing the housing 61 in the installation position, the bottom surface of the fixing pad 84 on the outside of the housing 61 is aligned with the air inlet duct 2. Then, the guide sliding block 82 is moved to move the limiting mounting sleeve 83, allowing it to pass through the mounting sleeve 85 and movably engage with the outside of the galvanized threaded rod 86. After threaded connection between the galvanized nut 87 and the galvanized threaded rod 86, the bottom surface of the galvanized nut 87 presses against the limiting mounting sleeve 83, conveniently completing the positioning and fixing of the housing 61, simplifying installation and subsequent maintenance operations.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
