[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A moisture-proof shore power control box for ships includes a control box body 1 and a sealing ring 2. The sealing ring 2 is fixedly connected to one side of the control box body 1. A cold air hole 3 and a hot air hole 4 are opened on the inner side of the right end of the control box body 1. A flow guiding assembly 5 is fixedly connected to the inner side of the control box body 1. A first drying assembly 6 and a second drying assembly 7 are fixedly connected to the right side of the control box body 1. The flow guiding assembly 5 includes a straight pipe 51, an air duct 52 is opened on the inner side of the straight pipe 51, a flared pipe 53 is fixedly connected to one side of the straight pipe 51, and a folded pipe 57 is fixedly connected to one side of the straight pipe 51. A first one-way valve 54 is fixedly connected to the inner side of the lower end of the pipe 57. A connecting plate 55 is fixedly connected to the inner side of the air duct 52 opened in the straight pipe 51. A fan 56 is fixedly connected to one side of the connecting plate 55.

A second one-way valve 63 is fixedly connected to the inner side of the external through hole 62 opened in the semi-through pipe 61. A filter screen 64 is fixedly connected to the inner side of the semi-through pipe 61. A water filter plate 65 is fixedly connected to the inner side of the semi-through pipe 61. A drying plate 66 is fixedly connected to the inner side of the semi-through pipe 61. A constant pressure hole 67 is opened at the lower end of the semi-through pipe 61. A fixed installation port 68 is opened at the upper end of the semi-through pipe 61.

[0030] As a further implementation of this solution, the electrical control box body 1 is sealed by the sealing ring 2. The cold air hole 3 and the hot air hole 4 both penetrate through the right end of the electrical control box body 1. The cold air hole 3 is connected to the inside of the electrical control box body 1. This sealing design effectively isolates the external environment from the inside of the control box, protects the internal components from the corrosion of moisture and salt spray, and thus improves the basic moisture resistance of the control box.

[0031] As a further implementation of this solution, there are two hot air vents 4 and two sets of cold air vents 3. The cold air vents 3 are located inside the left end of the semi-through pipe 61, and the hot air vents 4 are located outside the semi-through pipe 61. This layout helps to optimize the airflow path, improve heat dissipation and moisture-proof effect, and ensure the dryness and stability of the internal environment of the control box.

[0032] As a further implementation of this solution, the inner side of the folded tube 57 is hollow, there are two folded tubes 57, the shape of the folded tube 57 is L-shaped, the folded tube 57 is connected to the inside of the air duct 52, the number of folded tubes 57 is the same as the number of straight tubes 51, the lower end of the folded tube 57 is fixedly connected to the outside of the semi-through tube 61 near the fixed installation port 68, the inner side of the flared tube 53 is hollow, the two ends of the flared tube 53 are through structures, the flared tube 53 is connected to the inside of the air duct 52 opened by the straight tube 51, the right side of the flared tube 53 is fixedly connected to the inside of the right end of the electrical control box body 1, the right side of the flared tube 53 is outside the cold air hole 3, there are two flared tubes 53. This structural design helps to guide airflow and improve heat dissipation. This design allows air to flow freely inside the control box, improves heat dissipation efficiency, and can output hot air inside the electrical control box body 1 to improve the drying efficiency of the drying plate 66.

[0033] As a further implementation of this solution, the inner side of the semi-through pipe 61 is hollow, and the left end of the semi-through pipe 61 has a through structure. The outer through hole 62 communicates with the inside of the semi-through pipe 61. The constant pressure hole 67 passes through the lower end of the semi-through pipe 61 and communicates with the inside of the semi-through pipe 61. The left side of the semi-through pipe 61 is fixedly connected to the right side of the electrical control box body 1. The mechanism of the first drying component 6 is the same as that of the second drying component 7. The fixed installation port 68 passes through the upper end of the semi-through pipe 61, and the inner side of the semi-through pipe 61 is connected to one end of the first one-way valve 54 through the fixed installation port 68. The constant pressure hole 67 is located at the right end of the drying plate 66. Two rows of water filter plates 65 are arranged, and the two rows of water filter plates 65 are staggered. The top view of the water filter plate 65 is arc-shaped. The fixed installation port 68 is located at the right end of the drying plate 66. This reduces the impact of external humidity on the inside of the control box and improves the moisture-proof performance. Through continuous airflow exchange and the alternating drying of the air entering the electrical control box body 1 by the two drying plates 66, the continuous moisture-proof effect is ensured, the service life and safety of the control box are improved, and rainwater is prevented from affecting the drying performance of the drying plate 66.

[0034] Workflow: To achieve heat dissipation and ensure continuous moisture protection for the electrical control box 1, the electrical control box 1 is sealed by the sealing ring 2. The interior of the electrical control box 1 is in a sealed state. The upper and lower fans 56 are started, with their blades rotating in opposite directions. The upper fan 56 draws air into the air duct 52, creating negative pressure inside the air duct 52 through the straight pipe 51. Under this negative pressure, some external air enters the semi-through pipe 61 through the constant pressure hole 67. The constant pressure hole 67 has a small diameter to facilitate subsequent exhaust. Simultaneously, under the negative pressure, the second one-way valve 63 is open, and the upper first one-way valve 54 is closed. At this time, the external air passes through the filter screen 64 and comes into contact with the water filter plate 65. The water filter plate 65 blocks water droplets in the air, preventing water droplets from directly contacting the drying plate 66 during rainy days. After passing through the drying plate 66, the external air is further dehydrated. The system absorbs and dries the air. Dry air enters the flared pipe 53 and the air duct 52, achieving drying and cooling effects inside the electrical control box 1. At this time, the lower second drying component 7, driven by the lower fan 56, can draw away the hot air inside the electrical control box 1. The hot air enters the interior of the second drying component 7 through the lower straight pipe 51 and bend pipe 57. The first one-way valve 54 inside the second drying component 7 is open, and the second one-way valve 63 inside the second drying component 7 is closed. At this time, the hot air enters the interior of the semi-through pipe 61 near the right end of the drying plate 66. The air flows out from the constant pressure hole 67 opened in the second drying component 7, which dries the drying plate 66 inside the second drying component 7. When the air permeability of the upper drying plate 66 is poor, the two fans 56 are started in the opposite manner to achieve continuous heat dissipation and drying effects inside the electrical control box 1, ensuring the normal operation of the electrical control box 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
