Description

Technical Field

[0001] This utility model relates to the field of ship cargo hold ventilation and dehumidification technology, and in particular to an adjustable ship cargo hold ventilation and dehumidification device. Background Technology

[0002] During a ship's voyage at sea, the humidity inside the cargo hold is a key concern. Due to the high humidity in the marine environment, cargo exposed to high humidity for extended periods is highly susceptible to dampness, mold, rust, and corrosion. This is especially true for humidity-sensitive goods such as electronic products, textiles, and food. Excessive humidity can lead to a decline in cargo quality or even damage, causing significant economic losses to cargo owners and shipping companies.

[0003] Currently, air jet dehumidification is commonly performed in ship cargo holds using jet dehumidifiers. However, most existing jet dehumidifiers have fixed structures and very limited jet range, which results in some areas of the cargo hold not being effectively dehumidified, creating dehumidification dead zones. This leaves the cargo in these areas still at risk of becoming damp. To address this issue, we propose an adjustable ship cargo hold ventilation and dehumidification device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable ventilation and dehumidification device for ship cargo holds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable ship cargo hold ventilation and dehumidification device includes multiple protective boxes and a main air supply pipeline. A pushing mechanism is installed on one side of each protective box, and a rotating structure is installed on another side of each protective box. The pushing mechanism and the rotating structure are connected. A telescopic mechanism is installed on the rotating structure. An adjustment mechanism is connected to one end of the telescopic mechanism, and a rotating plate is connected to one end of the adjustment mechanism. A jet structure is connected to one side of the rotating plate, and the jet structure is connected to the main air supply pipeline.

[0007] Preferably, the pushing mechanism includes a second electric telescopic rod installed on one side inside the protective box. The second electric telescopic rod is fixed to one side inside the protective box by a second fixing member, and a connecting block is threaded onto one end of the second electric telescopic rod.

[0008] Preferably, the rotating structure includes two first fixing members fixed inside one side of the protective box, and a bearing tube is rotatably sleeved on the two first fixing members. A spiral guide groove is provided on the circumferential side wall of the bearing tube, and a limit rod is engaged in the spiral guide groove. The lower end of the limit rod is fixed to one side of the connecting block.

[0009] Preferably, the telescopic mechanism includes a first electric telescopic rod that is fixedly fitted inside the bearing tube.

[0010] Preferably, the adjustment mechanism includes a connecting arm rotatably connected to one end of the first electric telescopic rod, a rotating rod rotatably connected to one end of the connecting arm, a mounting block fixed to one end of the rotating rod, the mounting block penetrating the side wall of the protective box and fixed to one side of the rotating plate.

[0011] Preferably, the jet structure includes two air supply hoods installed on one side of the rotating plate, a nozzle is fixed on one side of the rotating plate, and the two air supply hoods and one nozzle are connected. A delivery pipe is connected to the middle of the nozzle, one end of the delivery pipe is connected to the main air supply pipeline, and a dustproof net is installed inside the air supply hood.

[0012] Preferably, two connecting plates are fixed on one side of the protective box.

[0013] The dehumidification process of this utility model is as follows:

[0014] 1. Gas delivery: The main gas pipeline serves as the gas supply source for the entire dehumidification device, delivering the treated dehumidified gas to the jet structure. The gas enters the nozzle through the delivery pipe, is then distributed to the two gas delivery hoods, and finally sprays out from the gas delivery hoods to dehumidify the air in the ship's cargo hold.

[0015] 2. Rotation Adjustment: Under the fixing action of the second fixed part, the second electric telescopic rod in the pushing mechanism reciprocates and extends within the protective box. The connecting block at one end of the second electric telescopic rod moves with its extension and retraction. The limiting rod on the connecting block is engaged in the spiral guide groove of the bearing tube. When the connecting block moves, the limiting rod slides along the spiral guide groove, thereby driving the bearing tube to reciprocate and rotate on the two first fixed parts. The rotation of the bearing tube is transmitted to the rotating plate through the mounting block, thereby realizing the reciprocating rotation of the jet structure and expanding the horizontal range of the jet.

[0016] 3. Angle Adjustment: The first electric telescopic rod of the telescopic mechanism is fixedly installed inside the bearing tube. When the first electric telescopic rod reciprocates, the adjustment mechanism composed of the connecting arm and the rotating rod will move accordingly. One end of the connecting arm is rotatably connected to the first electric telescopic rod, and the other end is connected to the rotating plate through the mounting block. The two ends of the rotating rod are rotatably connected to the first electric telescopic rod and the connecting arm, respectively. The extension and retraction of the first electric telescopic rod drives the angle of the connecting arm and the rotating rod to change, thereby causing the rotating plate to reciprocate to tilt, further expanding the vertical range of the jet.

[0017] This utility model has the following advantages:

[0018] 1. By using a pushing mechanism to drive a rotating structure to make the jet structure rotate back and forth, and a telescopic mechanism to drive an adjusting mechanism to tilt the jet structure back and forth, it is possible to achieve all-round and multi-angle jet dehumidification, effectively eliminate dehumidification dead corners in the warehouse, greatly improve the dehumidification effect, and reduce the risk of goods getting damp.

[0019] 2. Good dehumidification effect can ensure that the goods are always in a suitable humidity environment during transportation, reduce quality problems caused by moisture, protect the quality and safety of the goods, and avoid unnecessary economic losses for cargo owners and shipping companies.

[0020] 3. The adjustable jet structure allows the device to be flexibly adjusted according to the layout of different cargo holds and the stacking of goods, improving the adaptability and versatility of the device, and making it suitable for various types of ship cargo holds.

[0021] 4. Because the humidity inside the cargo hold is effectively controlled, the corrosion of equipment and structures by humid air is reduced, which helps to extend the service life of the equipment and reduce the maintenance cost of the ship.

[0022] In summary, this utility model can achieve all-round, multi-angle jet dehumidification, effectively eliminate dehumidification dead corners in the cargo warehouse, greatly improve the dehumidification effect, reduce the risk of goods getting damp, reduce quality problems caused by dampness, and ensure the quality and safety of goods. It can also be flexibly adjusted according to the layout of different cargo warehouses and the stacking of goods, improving the adaptability and versatility of the device, and is suitable for various types of ship cargo warehouses.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-5 An adjustable ship cargo hold ventilation and dehumidification device includes multiple protective boxes 13 and a main air supply pipeline 17. A pushing mechanism is installed on one side of the protective box 13, and a rotating structure is installed on another side of the protective box 13. The pushing mechanism and the rotating structure are connected. A telescopic mechanism is installed on the rotating structure. One end of the telescopic mechanism is connected to an adjustment mechanism. One end of the adjustment mechanism is connected to a rotating plate 11. One side of the rotating plate 11 is connected to a jet structure, and the jet structure is connected to the main air supply pipeline 17. The device is composed of multiple protective boxes 13 and a main air supply pipeline 17. The protective boxes 13 serve to protect the internal mechanisms, and the main air supply pipeline 17 is the main gas supply channel for the entire device.

[0031] The pushing mechanism includes a second electric telescopic rod 7 installed on one side inside the protective box 13. The second electric telescopic rod 7 is fixed to one side inside the protective box 13 by a second fixing member 8. A connecting block 16 is threaded to one end of the second electric telescopic rod 7. The threaded connection method facilitates installation and disassembly, and is convenient for later maintenance and replacement.

[0032] The rotating structure includes two first fixing parts 3 fixed to one side inside the protective box 13. A bearing tube 4 is rotatably sleeved on the two first fixing parts 3. A spiral guide groove 5 is provided on the circumferential side wall of the bearing tube 4. A limit rod 15 is locked in the spiral guide groove 5. The lower end of the limit rod 15 is fixed to one side of the connecting block 16. The limit rod 15 is locked in the spiral guide groove 5 and the lower end of the limit rod 15 is fixed to one side of the connecting block 16. When the connecting block 16 moves with the extension and retraction of the second electric telescopic rod 7, the limit rod 15 will slide along the spiral guide groove 5, thereby driving the bearing tube 4 to reciprocate on the two first fixing parts 3.

[0033] The telescopic mechanism includes a first electric telescopic rod 6 fixedly fitted inside the bearing tube 4. The bearing tube 4 enables the first electric telescopic rod 6 to rotate with the rotation of the bearing tube 4, while also being able to telescopically move independently.

[0034] The adjustment mechanism includes a connecting arm 1 rotatably connected to one end of the first electric telescopic rod 6, a rotating rod 2 rotatably connected to one end of the connecting arm 1, a mounting block 19 fixed to one end of the connecting arm 1, the mounting block 19 penetrating the side wall of the protective box 13 and fixed to one side of the rotating plate 11. When the first electric telescopic rod 6 extends or retracts, the adjustment mechanism composed of the connecting arm 1 and the rotating rod 2 will move accordingly, thereby causing the rotating plate 11 to change angle.

[0035] The jet structure includes two gas supply hoods 10 installed on one side of the rotating plate 11. A nozzle 12 is fixed on one side of the rotating plate 11, and the two gas supply hoods 10 and the nozzle 12 are connected. A delivery pipe 9 is connected to the middle of the nozzle 12. One end of the delivery pipe 9 is connected to the main gas supply line 17. A dustproof net 18 is installed inside the gas supply hood 10. The gas in the main gas supply line 17 can enter the nozzle 12 and the gas supply hood 10 through the delivery pipe 9. The dustproof net 18 can effectively prevent dust and other impurities from entering the gas supply hood 10 and the nozzle 12, ensuring the cleanliness and smoothness of the jet, and also extending the service life of the device.

[0036] Two connecting plates 14 are fixed on one side of the protective box 13. The connecting plates 14 can be used to fix the protective box 13 in a suitable position in the cargo hold of the ship, which facilitates the installation and fixation of the entire device.

[0037] The dehumidification process of this utility model is as follows:

[0038] 1. Gas delivery: The main gas pipeline 17 serves as the gas supply source for the entire dehumidification device, delivering the treated dehumidified gas to the jet structure. The gas enters the nozzle 12 through the delivery pipe 9, and is then distributed to the two gas delivery hoods 10. Finally, it is ejected from the gas delivery hoods 10 to dehumidify the air in the ship's cargo hold.

[0039] 2. Rotation Adjustment: Under the fixing action of the second fixed part 8, the second electric telescopic rod 7 in the pushing mechanism reciprocates within the protective box 13. The connecting block 16 at one end of the second electric telescopic rod 7 moves with its extension and retraction. The limiting rod 15 on the connecting block 16 is engaged in the spiral guide groove 5 of the bearing pipe 4. When the connecting block 16 moves, the limiting rod 15 slides along the spiral guide groove 5, thereby driving the bearing pipe 4 to reciprocate on the two first fixed parts 3. The rotation of the bearing pipe 4 is transmitted to the rotating plate 11 through the mounting block 19, thereby realizing the reciprocating rotation of the jet structure and expanding the horizontal range of the jet.

[0040] 3. Angle Adjustment: The first electric telescopic rod 6 of the telescopic mechanism is fixedly installed inside the bearing tube 4. When the first electric telescopic rod 6 reciprocates, the adjustment mechanism composed of the connecting arm 1 and the rotating rod 2 will move accordingly. One end of the connecting arm 1 is rotatably connected to the first electric telescopic rod 6, and the other end is connected to the rotating plate 11 through the mounting block 19. The two ends of the rotating rod 2 are rotatably connected to the first electric telescopic rod 6 and the connecting arm 1, respectively. The extension and retraction of the first electric telescopic rod 6 drives the angle of the connecting arm 1 and the rotating rod 2 to change, thereby causing the rotating plate 11 to reciprocate to tilt, further expanding the vertical range of the jet.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
