DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] If electrical components appear in the text, they are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. At the same time, if motors, water pumps, feed pumps and hydraulic cylinders appear in the text, they are all existing known devices.

[0020] See also Figure 1-3 The present invention provides a technical solution: a cargo hold ventilation device with filtering function for transport ships, comprising a filter pipe 1, an activated carbon filter layer 2, a filter screen 3, a ventilation pipe 4, a shutter 5, a baffle 6, a motor 7, a connecting shaft 8, a gear 9, a latch 10, a rotating disk 11, a threaded rod 12, a ventilation pipe cover 13, a reset spring 14 and a buffer block 15, an activated carbon filter layer 2 is arranged in the filter pipe 1, and a filter screen 3 is arranged on the left side of the activated carbon filter layer 2, and the filter screen 3 is arranged in the filter pipe 1, and the ventilation pipe 4 is arranged on the left side of the filter pipe 1, and the shutter 5 is arranged at the bottom of the ventilation pipe 4, and A baffle 6 is provided in the ventilation duct 4, a motor 7 is provided on the left side of the ventilation duct 4, and the motor 7 is connected to the gear 9 through the connecting shaft 8, and the gear 9 is connected to the latch 10, the latch 10 is provided on the outer side of the rotating disk 11, and the rotating disk 11 is provided on the inner side of the ventilation duct 4, a threaded rod 12 passes through the rotating disk 11, and the threaded rod 12 is provided on the lower side of the ventilation pipe cover 13, and the ventilation pipe cover 13 is provided on the upper side of the ventilation duct 4, a reset spring 14 is provided in the body wall of the ventilation duct 4, and the ventilation duct 4 is connected to the buffer block 15 through the reset spring 14, and the buffer block 15 is provided at the upper end of the ventilation duct 4.

[0021] The activated carbon filter layers 2 of this example are evenly spaced in the filter pipe 1, and the length and width of the activated carbon filter layers 2 are equal to the length and width of the filter mesh 3. The humid air is filtered through the filter mesh 3 and then filtered through the activated carbon filter layer 2 to dry the humid air, making it easier to filter the air and prevent impurities from entering the room. At the same time, it prevents the indoor humidity from rising and causing damage to the product.

[0022] The baffle 6 is in a truncated cone shape, and the horizontal height of the baffle 6 is equal to the horizontal height of the upper end of the filter pipe 1. Rainwater drops on the baffle 6, slides down the baffle 6, and flows out of the shutter 5, which is convenient for preventing rainwater from entering.

[0023] The rotating disk 11 is rotatably connected to the ventilation duct 4, and the inner diameter and outer diameter of the rotating disk 11 are equal to the inner diameter and outer diameter of the ventilation duct 4. At the same time, the latching teeth 10 on the rotating disk 11 are meshingly connected with the gear 9. The motor 7 drives the gear 9 to rotate through the connecting shaft 8. When the gear 9 rotates, the rotating disk 11 is rotated through the latching teeth 10, so that the threaded rod 12 moves downward, thereby lowering the ventilation pipe cover 13, which is convenient for changing the height of the ventilation pipe cover 13. The ventilation pipe cover 13 can be engaged with the ventilation duct 4 in rainy and snowy weather.

[0024] The ventilation pipe cover 13 is in a "concave" shape, and the ventilation pipe cover 13 is snap-fitted to the ventilation duct 4. At the same time, the threaded rod 12 on the lower side of the ventilation pipe cover 13 is threadedly connected to the rotating disk 11, which improves the compactness of the ventilation duct 4 and prevents rainwater from entering.

[0025] The buffer block 15 is a telescopic structure with the ventilation duct 4 through the return spring 14, and the buffer blocks 15 are distributed at equal angles on the ventilation duct 4. The ventilation pipe cover 13 squeezes the buffer block 15, so that the buffer block 15 is compressed by the return spring 14, which is convenient for buffering the ventilation pipe cover 13 and improves the safety of the ventilation pipe cover 13.

[0026] Working principle: When using the cargo hold ventilation device with filtering function for transport ships, during sea transportation, humid air enters from the upper and lower ends of the ventilation duct 4, and is filtered through the filter 3 to filter out dust in the humid air to prevent impurities from entering the room. The humid air is filtered through the activated carbon filter layer 2 to dry the humid air, avoiding the indoor humidity from rising and making the product damp. When it rains, rainwater enters from the upper end of the ventilation duct 4 and flows out from the shutter 5. Part of the rainwater drips on the baffle 6, slides down the baffle 6, and flows out from the shutter 5. At the same time, the power is turned on and the motor 7 is started. The motor 7 drives the gear 9 to rotate through the connecting shaft 8. While the gear 9 rotates, the rotating disk 11 is rotated through the latching teeth 10, so that the threaded rod 12 moves downward, thereby lowering the ventilation pipe cover 13. The ventilation pipe cover 13 squeezes the buffer block 15, and the buffer block 15 is compressed by the return spring 14 to buffer the descending ventilation pipe cover 13 until the ventilation pipe cover 13 is engaged with the ventilation duct 4, thereby improving the compactness of the ventilation duct 4 and preventing rainwater from entering. The motor 7 is turned off. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
