[0029] The inner gear ring 1103 forms a rotating structure with the ventilation box 1 through the interaction between the guide block 1104 and the guide groove 1105;

[0030] Specifically, Figure 2 , Figure 3 As shown, when in use, the gear 1102 and the inner gear ring 1103 mesh to realize the rotation of the inner gear ring 1103, thereby driving the scraper 10 to scrape the inner wall of the ventilation box 1 to reduce the adhesion of condensation to the wall, and combined with the function of the drain pipe 13, it is convenient to collect the accumulated water separately to reduce the pollution inside the ventilation box 1;

[0031] Scrapers 10 are installed at both ends of one side of the anti-condensation mechanism 11, one end of the scraper 10 is connected to a guide ring 9, and a filter screen 8 is installed inside the ventilation box 1 on one side of the guide ring 9, one side of the scraper 10 is in contact with the inner wall of the ventilation box 1, a drain pipe 13 is installed at the bottom end of the ventilation box 1, and a water collecting box 7 is provided outside the drain pipe 13;

[0033] A sealing ring 15 is provided at the top of the water collecting box 7, and fixing blocks 6 are installed on both sides of the water collecting box 7, and mounting mechanisms 14 are provided inside the fixing blocks 6;

[0034] The mounting mechanism 14 includes a positioning rod 1401, and the positioning rod 1401 passes through the interior of the fixing block 6, a limiting plate 1404 is sleeved on the exterior of the positioning rod 1401, and both ends of one side of the limiting plate 1404 are installed with extrusion springs 1403, one end of the extrusion spring 1403 is connected to one side of the interior of the fixing block 6, a pull ring 1402 is installed at one end of the positioning rod 1401, and a positioning hole 1405 is opened on one side of the drain pipe 13 at the other end of the positioning rod 1401, and one end of the positioning rod 1401 extends to the interior of the positioning hole 1405;

[0035] Specifically, Figure 3 , Figure 4 and Figure 5As shown, when in use, the elastic action of the squeezing spring 1403 is used to push the positioning rod 1401 into the interior of the positioning hole 1405, so that a supporting connection is formed between the water collecting box 7 and the drain pipe 13 through the positioning rod 1401 to ensure the installation of the water collecting box 7.

[0036] Working principle: When the utility model is in use, firstly, when the ship is moving forward, the air guide cover 3 cooperates with the air guide groove 4 to guide the airflow, and then further drives the ventilation blades 5 to rotate, so as to promote the airflow inside the ventilation pipe 2 and improve the ventilation efficiency;

[0037] Secondly, the condenser 12 is started synchronously to cool the gas inside the ventilation box 1 to reduce the dissipation of cold air in the ship's cold storage during ventilation, and the rotating motor 1101 is started at the same time to make the shaft drive the gear 1102 to rotate. Since the gear 1102 and the inner gear ring 1103 are meshed with each other, the inner gear ring 1103 is driven to rotate, so as to drive the scraper 10 to scrape the inner wall of the ventilation box 1. Since the interior of the ventilation box 1 is a low-temperature environment, it is easy for the gas to adhere to the interior of the ventilation box 1 during circulation and condense. Under the scraping action of the scraper 10, the condensation is scraped off, so that it enters the interior of the drain pipe 13 and then falls into the interior of the water collecting box 7 for centralized treatment. Then the airflow passes through the filtering effect of the filter 8 and enters the interior of the ship's cold storage.

[0038] Finally, by pulling the pull ring 1402 outward, the positioning rod 1401 drives the limiting plate 1404 to move outward, compressing the extrusion spring 1403, so that the positioning rod 1401 is moved out of the positioning hole 1405, thereby facilitating the removal of the water collecting box 7 downward, so as to facilitate regular cleaning of the water collecting box 7.
