Description

Technical Field

[0001] This utility model relates to the field of marine air conditioning technology, specifically a ventilation structure for marine air conditioning. Background Technology

[0002] Ship air conditioning and ventilation systems play a vital role in the ocean shipping industry as devices for regulating the temperature of enclosed air in ship cabins. Since ship cabins are mostly enclosed, ship air conditioning and ventilation systems can improve air circulation and control the temperature inside the cabins.

[0003] For example, Chinese utility model patent CN215155573U discloses a ventilation mechanism for ship air conditioning, which includes a rectangular duct. A fan for drawing outside air into the cabin is installed inside the rectangular duct. An iron mesh for preventing external debris from entering the rectangular duct is fixedly installed on the air intake side of the duct. A box with an open top is detachably and fixedly inserted into the side of the rectangular duct near the air outlet. The box has notches on both the front and rear sides, and a breathable mesh is fixedly connected to each of the notches. A desiccant capable of absorbing moisture from the air is placed inside the box. This utility model, through the box installed inside the rectangular duct, allows the desiccant to absorb moisture-containing substances from the air when air is inside the box, reducing the humidity and preventing excessive humidity in the cabin that could cause discomfort to personnel or dampness to equipment.

[0004] However, the existing ventilation structure for ship air conditioning is not easy to disassemble and assemble during use, and it is not easy to remove and clean the filter screen installed inside the mesh holes.

[0005] Therefore, we propose a ventilation structure for ship air conditioning to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4 This is the first embodiment of the present utility model, which provides a technical solution: a ventilation structure for ship air conditioning, including a rectangular pipe 1 and a fixed frame 8. A fixed plate 2 is fixedly installed inside the rectangular pipe 1. A motor 3 is fixedly installed on one side of the fixed plate 2. One end of a connecting rod 31 is fixedly connected to the shaft of the motor 3. A fan 4 is fixedly installed on the other end of the connecting rod 31. The motor 3 is connected to an external power supply. By starting the motor 3, the connecting rod 31 and the fan 4 can be driven to rotate inside the rectangular pipe 1 to achieve the effect of air suction. A ventilation filter plate 13 is in contact inside the fixed frame 8. Threaded grooves 131 are opened on both sides of the ventilation filter plate 13. Through holes 83 are opened on both sides of the fixed frame 8. A limiting rod 14 is movably connected inside the through holes 83. The threaded part of the limiting rod 14 is threadedly connected to the threaded groove 131. Unscrewing the limiting rod 14 facilitates the disassembly and assembly of the ventilation filter plate 13.

[0024] Positioning blocks 1 and 5 are fixedly connected to both ends of one side of the rectangular pipe 1. A slot 51 is opened in the positioning block 1 and 6 are fixedly connected to both ends of one side of the rectangular pipe 1. The fixed frame 8 contacts the positioning blocks 1 and 6. A sliding groove 82 is opened at both ends of one side of the fixed frame 8. One end of the spring 10 is fixedly connected to one side of the sliding groove 82. The other end of the spring 10 is fixedly connected to the slider 11. The slider 11 is slidably connected to the sliding groove 82. A locking block 12 is fixedly connected to the side of the slider 11 away from the spring 10. The locking block 12 engages with the slot 51, which can install and fix the fixed frame 8.

[0025] Example 2:

[0026] Please see Figure 1-4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A toggle plate 112 is fixedly connected to one side of the slider 11. The toggle plate 112 is slidably connected to the slide groove 82 to facilitate the movement of the slider 11.

[0027] Positioning rods 7 are fixedly connected to both ends of one side of the rectangular pipe 1, and positioning holes 81 are opened at both ends of one side of the fixed frame 8. The positioning holes 81 are slidably connected to the positioning rods 7, which can further limit the position of the fixed frame 8 and facilitate installation.

[0028] Multiple blocks 9 are fixedly connected inside the fixed frame 8. The ventilation filter plate 13 contacts the blocks 9, which can limit the movement of the ventilation filter plate 13.

[0029] Limiting blocks 111 are fixedly connected to both sides of the slider 11, and limiting grooves 821 are opened on both sides of the slide groove 82. The limiting blocks 111 are slidably connected to the limiting grooves 821 to improve the stability of the slider 11 movement and limit the movement range of the slider 11.

[0030] Through hole 83 and threaded groove 131 are internally connected.

[0031] Example 3:

[0032] Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the above two embodiments. In actual use, when it is necessary to disassemble the fixed frame 8, the slider 11 is moved by moving the upper and lower end plates 112 to compress the spring 10, so that the locking block 12 moves into the fixed frame 8, so that the locking block 12 disengages from the slot 51. The fixed frame 8 can then be slid out of the positioning rod 7 for disassembly. When it is necessary to clean or replace the ventilation filter plate 13 separately, the limiting rods 14 at both ends are unscrewed to disengage the limiting rods 14 from the threaded groove 131. The ventilation filter plate 13 can then be disassembled separately for cleaning or replacement. The operation is convenient.

[0033] 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.
