Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for power distribution cabinets, and in particular to an auxiliary heat dissipation device for ship power distribution cabinets. Background Technology

[0002] Marine electrical distribution cabinets are electrical devices specifically designed for use in marine environments. They are primarily used to distribute and manage the electrical energy required for various electrical loads on board. As one of the core components of the ship's electrical system, they are responsible for receiving power from the main generator or shore power and distributing it safely and efficiently to various electrical devices and subsystems, such as lighting, navigation equipment, communication systems, and propulsion systems.

[0003] To meet heat dissipation requirements, existing shipboard power distribution cabinets typically require ventilation openings on the cabinet body. However, relying solely on ventilation openings results in low heat dissipation efficiency, and the cabinet body is in a high-humidity environment for extended periods, making it easy for moisture to enter the cabinet body through the ventilation openings, which can affect the safe operation of internal electronic components.

[0004] Therefore, an auxiliary heat dissipation device for shipboard power distribution cabinets has been developed that can effectively improve the heat dissipation efficiency of the power distribution cabinet, while preventing moisture from entering the power distribution cabinet and ensuring the safe operation of internal electronic components. Utility Model Content

[0005] To overcome the shortcomings of existing ship power distribution cabinets, which rely solely on ventilation vents for ventilation, resulting in low heat dissipation efficiency and the cabinet being in a high-humidity environment for extended periods, allowing moisture to easily enter the cabinet through the vents and affecting the safe operation of internal electronic components, this utility model provides an auxiliary heat dissipation device for ship power distribution cabinets that can effectively improve the heat dissipation efficiency of the power distribution cabinet while preventing moisture from entering the cabinet and ensuring the safe operation of internal electronic components.

[0006] The technical solution of this utility model is: an auxiliary heat dissipation device for a ship's electrical distribution cabinet, comprising an electrical distribution cabinet, a cabinet door, a moisture-proof base, a connecting frame, a socket frame, louvers, a filter screen, a waterproof sealing strip, bolts, a fan, a dehumidification component, and a locking component. The cabinet door is rotatably connected to the front left side of the electrical distribution cabinet, and a moisture-proof base is connected to the lower side of the electrical distribution cabinet. The left and right sides of the electrical distribution cabinet are detachably connected to two connecting frames by multiple bolts. A socket frame is snapped onto each connecting frame, and multiple louvers are rotatably connected to each socket frame by damping. A filter screen is snapped into each socket frame. A waterproof sealing strip is snapped onto the side of each connecting frame near the electrical distribution cabinet, and the waterproof sealing strip is in contact with the electrical distribution cabinet. A fan is connected inside each connecting frame. A dehumidification component that can prevent moisture from entering the electrical distribution cabinet is provided on the connecting frame, and a locking component that can fix the dehumidification component is also provided on the connecting frame.

[0007] In addition, it is particularly preferred that a handle is provided on the front right side of the cabinet door.

[0008] Furthermore, it is particularly preferred that the dehumidification assembly includes a mesh sleeve and a cover, with a mesh sleeve placed in the middle of the connecting frame and a cover snapped onto the upper side of the mesh sleeve.

[0009] In addition, it is particularly preferred that the cover also includes a handle, with a handle attached to the upper side of the cover.

[0010] Furthermore, it is particularly preferred that the locking assembly includes a sliding rod, an elastic element, and a locking rod. The front and rear parts of the connecting frame are slidably connected to the sliding rod, and the sliding rod is connected to the connecting frame by an elastic element. The locking rod is rotatably connected to the sliding rod, and the locking rod engages with the adjacent mesh sleeve.

[0011] Furthermore, it is particularly preferred that the elastic element be a spring.

[0012] The beneficial effects are as follows: By starting the fan, the air circulation speed in the distribution cabinet is accelerated, the filter screen filters impurities in the air, and the desiccant in the mesh sleeve adsorbs moisture in the air, thereby effectively improving the heat dissipation efficiency of the distribution cabinet and preventing moisture from entering the distribution cabinet, ensuring the safe operation of the internal electronic components.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] An auxiliary heat dissipation device for a ship's electrical distribution cabinet, such as Figures 1-6 As shown, the device includes a distribution cabinet 1, a cabinet door 2, a moisture-proof base 3, a connecting frame 4, a socket frame 5, louvers 6, a filter screen 7, a waterproof sealing strip 8, bolts 9, a fan 16, a dehumidification assembly, and a locking assembly. The cabinet door 2 is rotatably connected to the front left side of the distribution cabinet 1. A handle is provided on the front right side of the cabinet door 2 for easy gripping. The moisture-proof base 3 is connected to the lower side of the distribution cabinet 1. The upper and lower connecting frames 4 are detachably connected to both sides of the distribution cabinet 1 by four bolts 9. Each connecting frame 4 is fitted with a socket frame 5, and each socket frame 5 is connected to fifteen louvers 6 via a damping rotation. Each socket frame 5 is fitted with a filter screen 7. Each connecting frame 4 is fitted with a waterproof sealing strip 8 on the side near the power distribution cabinet 1. Each waterproof sealing strip 8 is in contact with the power distribution cabinet 1. Each connecting frame 4 is connected to a fan 16. The connecting frame 4 is equipped with a dehumidification component and a locking component.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, the dehumidification assembly includes a mesh sleeve 10, a cover 11, and a handle 12. The mesh sleeve 10 is placed in the middle of the connecting frame 4. The cover 11 is snapped onto the upper side of the mesh sleeve 10. The handle 12 is connected to the upper side of the cover 11.

[0023] like Figure 1 , Figure 3 and Figure 5 As shown, the locking assembly includes a sliding rod 13, an elastic element, and a locking rod 15. The sliding rod 13 is slidably connected to both the front and rear parts of the connecting frame 4. An elastic element, which is a spring 14, is connected between each sliding rod 13 and the connected connecting frame 4. The locking rod 15 is rotatably connected to each sliding rod 13. The locking rod 15 is engaged with the adjacent mesh sleeve 10.

[0024] When using this utility model, first place the power distribution cabinet 1 in the ship's power distribution position, with the moisture-proof base 3 in contact with the ship to prevent moisture from entering the power distribution cabinet 1 from the bottom. Then, open the cabinet door 2 and install electronic components inside the power distribution cabinet 1. After installation, close the cabinet door 2. Then, use the bolts 9 to install the connecting frame 4 onto the power distribution cabinet 1. The waterproof sealing strip 8 contacts the power distribution cabinet 1 to enhance the sealing between the connecting frame 4 and the power distribution cabinet 1. Then, place the filter screen 7 into the socket frame 5 and fix the socket frame 5 onto the connecting frame 4. Then, according to the heat dissipation requirements of the power distribution cabinet 1, rotate and adjust the angle of the louvers 6 to control the opening size of the socket frame 5. Then, remove the cover 11 using the handle 12, put the desiccant into the mesh sleeve 10, and close it afterward. When the power distribution cabinet 1 is running, the cover 11 can activate the fan 16 to accelerate the air circulation inside the power distribution cabinet 1. The filter 7 filters impurities in the air, and the desiccant in the mesh sleeve 10 adsorbs moisture in the air, thereby effectively improving the heat dissipation efficiency of the power distribution cabinet 1 and preventing moisture from entering the power distribution cabinet 1, ensuring the safe operation of the internal electronic components. When it is necessary to remove the mesh sleeve 10, the sliding rod 13 can be pulled to move the locking rod 15 away from the mesh sleeve 10. The spring 14 is stretched, and then the locking rod 15 is rotated to move it away from the mesh sleeve 10, so that the mesh sleeve 10 can be removed from the connecting frame 4. After releasing the sliding rod 13, the spring 14 rebounds, causing the sliding rod 13 to return to its original position.
