Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrosion prevention technology for marine power equipment, and more specifically, to marine power supply equipment based on clean energy. Background Technology
[0002] To reduce greenhouse gas and pollutant emissions from ships at sea, most ships now use clean energy-based power supply equipment. This equipment mainly uses renewable energy or low-carbon energy technologies to replace traditional fossil fuel (such as diesel and heavy oil) ship propulsion systems, thereby reducing greenhouse gas and pollutant emissions.
[0003] When sailing at sea, seawater accelerates the corrosion of metal materials. Therefore, most existing power supply equipment is equipped with an anti-corrosion shell to prevent seawater from entering the equipment during navigation. However, while the existing shell needs to provide corrosion protection, it also needs to ensure heat dissipation. Therefore, most existing shells have ventilation openings for heat dissipation. Although the shell as a whole can still prevent seawater from directly entering the equipment, in the humid environment at sea, seawater can form salt spray and enter the shell through the ventilation openings, still causing corrosion of the metal components inside the power supply equipment. Utility Model Content
[0004] This utility model provides a clean energy-based marine power supply device, which effectively prevents salt spray corrosion by setting an inclined S-shaped heat dissipation vent. The outer port of the vent is inclined downward to use gravity to block salt spray intrusion, while the inner port is inclined upward to follow the direction of hot air exhaust. Combined with the arc-shaped concave surface of the guide plate and the S-shaped path of the vent, salt spray is circulated back and blown out. Furthermore, a movable baffle can close the vent for further protection in harsh environments, thereby solving the problems in the aforementioned background technology, namely:
[0005] Salt spray from seawater can enter the supply equipment through the vents of the traditional corrosion-resistant casing, causing corrosion to the metal components inside the equipment.
[0006] To achieve the above objectives, the clean energy-based marine power supply equipment includes a waterproof casing. A power supply device is installed inside the waterproof casing. A mounting groove is provided on one side of the waterproof casing, and a heat dissipation plate is slidably installed inside the mounting groove. Two No. 2 bolts are threaded onto one side of the heat dissipation plate, and the heat dissipation plate is fixedly connected to the waterproof casing via the No. 2 bolts. Several obliquely oriented heat dissipation vents are provided through one side of the heat dissipation plate. The side cross-sectional shape of each heat dissipation vent is an inclined "S" shape. Two guide plates are installed inside each heat dissipation vent, with the arc-shaped concave surfaces of both guide plates facing outwards from the waterproof casing.
[0007] In the above scheme, when salt spray enters the heat dissipation port, the heat dissipation port uses an internal S-shaped bend and guide plate to cause the salt spray to flow back, preventing some of the salt spray from entering the waterproof outer cover. When the power supply device dissipates heat, the heat dissipation airflow blows out from the heat dissipation port, blowing out the salt spray trapped in the heat dissipation port and alleviating the corrosion of the inner wall of the heat dissipation port by the salt spray.
[0008] Based on this, the heat dissipation vents facing the outer side of the waterproof cover are tilted downwards by 10°–15° to block salt spray from directly intruding by gravity, while the heat dissipation vents facing the inner side of the waterproof cover are tilted upwards by 10°–15° to follow the upward direction of hot air and enhance the efficiency of heat dissipation airflow.
[0009] In another technical solution, two mounting grooves are formed on the top surface of the inner wall of the heat dissipation port, and the guide plate is slidably connected inside the mounting grooves;
[0010] One end of each of the two guide plates is fixedly connected to a connecting plate, and one end of the connecting plate is threadedly connected to a bolt of number one. The connecting plate is fixedly connected to the heat sink plate by the bolt of number one. Two extension support grooves are opened on one side of the inner wall of the heat sink. The other end of the guide plate is slidably connected to the inside of the extension support groove.
[0011] In this technical solution, the heat sink and the air guide plate adopt a modular design for easy and quick assembly and disassembly. The heat sink slides into the waterproof cover via the mounting groove and is secured by bolt number two; loosening the bolt allows it to slide out for replacement. The air guide plate is secured to bolt number one via a connecting plate; disassembly is achieved by simply unscrewing the bolt and sliding it out along the mounting groove, while installation is done in reverse. The extension support groove and the sliding groove work together to ensure the stability of the air guide plate installation, significantly simplifying the maintenance process and reducing downtime and labor costs.
[0012] In another technical solution, guide grooves are provided on both sides of the inner wall of the mounting groove, and a movable baffle is slidably connected between the two guide grooves. The size of the movable baffle is adapted to the size of the heat sink.
[0013] Steering columns are fixedly connected to the inner walls of the two guide grooves near their top ends. The movable baffle is slidably connected to the two steering columns. When the bottom of the movable baffle slides to the steering column, the movable baffle can rotate around the steering column as an axis.
[0014] The top surface of the waterproof cover has a storage groove, and the movable baffle is slidably connected to the storage groove.
[0015] In this technical solution, the movable baffle can be slid up and transferred into the storage tank, thereby exposing the heat dissipation plate to allow the device to dissipate heat. When not in operation or under harsh sea conditions, the movable baffle can slide to close the heat dissipation plate, further preventing salt spray intrusion and significantly extending the service life of the equipment.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] In this clean energy-based marine power supply equipment, the device achieves highly efficient protection against salt spray corrosion through optimized heat dissipation port structure. The heat dissipation port adopts an inclined S-shaped channel design, with the outer port tilted downwards at 10°–15° to utilize gravity to block direct salt spray intrusion; the inner port tilted upwards at 10°–15° to align with the rising direction of hot air and enhance the efficiency of heat dissipation airflow discharge. Double guide plates are installed inside the channel, with their arc-shaped concave surfaces facing outwards. Working in conjunction with the S-shaped path, they force the salt spray to reflux and converge into droplets at the first bend, ultimately being blown out by the heat dissipation airflow. This prevents salt spray from accumulating and corroding the inner wall. Furthermore, the movable baffle can slide to close the heat dissipation plate when not in operation or under harsh sea conditions, further blocking salt spray intrusion and significantly extending the equipment's service life.
[0018] Meanwhile, the heat sink and air deflector adopt a modular design for easy and quick assembly and disassembly. The heat sink slides into the waterproof cover via a mounting slot and is secured by bolt #2; simply loosen the bolt to slide it out for replacement. The air deflector is secured to bolt #1 via a connecting plate; disassembly is achieved by simply unscrewing the bolt and sliding it out along the mounting groove, while installation is done in reverse. The extended support groove cooperates with the sliding groove to ensure the stability of the air deflector installation. This design significantly simplifies the maintenance process, reducing downtime and labor costs. Attached Figure Description

[0030] 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.
[0031] Currently, the problem of salt spray from seawater entering the power supply equipment through the ventilation openings of traditional corrosion-resistant casings, leading to corrosion of internal metal components, is addressed in this invention. This invention provides a clean energy-based marine power supply device. (See [link to related document]). Figure 1 - Figure 4 As shown, the device includes a waterproof cover 1, inside which a power supply device is installed, and a cooling fan is installed inside the waterproof cover 1 to dissipate heat from the power supply device. The cooling fan blows hot air toward the heat dissipation port 21. Since the heat dissipation port of traditional equipment is in contact with salt spray for a long time, it is prone to corrosion. In this device, in order to avoid replacing the entire waterproof cover 1 when the heat dissipation port corrodes, an installation groove 14 is provided on one side of the waterproof cover 1. A heat dissipation plate 2 is slidably installed inside the installation groove 14. Two No. 2 bolts 24 are threadedly connected to one side of the heat dissipation plate 2. The heat dissipation plate 2 is fixedly connected to the waterproof cover 1 by the No. 2 bolts 24.
[0032] Traditional equipment typically has straight heat dissipation outlets, allowing salt mist to easily pass through. Therefore, in this device, several obliquely arranged heat dissipation ports 21 are provided through one side of the heat dissipation plate 2. The side cross-section of the heat dissipation port 21 is an inclined "S" shape. Two guide plates 221 are installed inside the heat dissipation port 21. The arc-shaped concave surfaces of the two guide plates 221 face the outside of the waterproof cover 1. When salt mist enters the heat dissipation port 21, the heat dissipation port 21 causes the salt mist to flow back through the internal S-shaped bend and the guide plates 221, preventing some of the salt mist from entering the waterproof cover 1. When the power supply device dissipates heat, the cooling airflow blows out from the heat dissipation port 21, blowing out the salt mist trapped inside the heat dissipation port 21 and alleviating the corrosion of the inner wall of the heat dissipation port 21 by the salt mist.
[0033] When implementing, see Figure 6 As shown, the heat dissipation vent 21 is tilted downwards at 10°–15° towards the outer side of the waterproof cover 1, and tilted upwards at 10°–15° towards the inner side of the waterproof cover 1. Due to the influence of gravity, the outer end of the heat dissipation vent 21 is tilted downwards, which can effectively prevent salt spray from directly entering its interior. Moreover, through the S-shaped bend, most of the salt spray will be blocked at the first bend and will converge into salt water flowing down at the first bend. The reason why the inner end of the heat dissipation vent 21 is tilted upwards is that hot air usually diffuses upwards. Therefore, the heat generated by the power supply equipment can easily enter its interior from the inner end of the heat dissipation vent 21. Under the action of the cooling fan inside the equipment, the hot air is blown out from the heat dissipation vent 21, and at the same time, the salt water that has gathered at the outer end of the heat dissipation vent 21 is also blown out.
[0034] In addition, the deflector plate 221 also blocks the salt spray entering the heat dissipation port 21. Therefore, the deflector plate 221 is also prone to corrosion after long-term use. It is recommended that the staff replace the deflector plate 221 every two months. In order to facilitate the staff to replace the deflector plate 221, two mounting grooves 211 are opened on the top surface of the inner wall of the heat dissipation port 21. The deflector plate 221 is slidably connected inside the mounting grooves 211.
[0035] Two guide plates 221 are fixedly connected to one end of a connecting plate 22. One end of the connecting plate 22 is threaded with a bolt 23. The connecting plate 22 is fixedly connected to the heat sink 2 through the bolt 23. The two guide plates 221 are connected as a whole through the connecting plate 22. One side of the heat sink 2 is penetrated by the heat dissipation port 21, and the other side is sealed. Two extension support grooves 212 are opened on one side of the inner wall of the heat dissipation port 21. The other end of the guide plate 221 is slidably connected to the inside of the extension support groove 212. After the staff slides a set of guide plates 221 into the installation groove 211, the end of the guide plate 221 near the inner wall of the heat dissipation port 21 can enter the extension support groove 212 through the guiding action of the installation groove 211. The extension support groove 212 can balance the supporting force on both ends of the guide plate 221.
[0036] In another technical solution, guide grooves 12 are provided on both sides of the inner wall of the mounting groove 14, and a movable baffle 3 is slidably connected between the two guide grooves 12. The size of the movable baffle 3 is adapted to the size of the heat sink 2. The movable baffle 3 can close the heat sink 2 when the supply equipment is not working or when the waves are large and seawater can easily enter the heat sink 21.
[0037] When implementing, see Figure 2 , Figure 3 and Figure 7As shown, the inner walls of the two guide grooves 12 are fixedly connected to steering columns 13 near the top. The movable baffle 3 is slidably connected to the two steering columns 13. When the operator needs to open the movable baffle 3 to expose the heat sink 2, the operator can gently push the movable baffle 3 upwards. When the bottom of the movable baffle 3 slides to the position of the steering column 13, the operator can push the movable baffle 3 towards the side closer to the waterproof cover 1. At this time, the movable baffle 3 can rotate around the steering column 13 as the axis. The top surface of the waterproof cover 1 is provided with a storage groove 11, and the movable baffle 3 can be stored in the storage groove 11, which reduces the space occupied by the movable baffle 3 and facilitates the operation of the operator.
[0038] The working principle of this device is as follows:
[0039] In the initial state, the movable baffle 3 is located in the mounting slot 14 and completely blocks the heat sink 2. When it is necessary to dissipate heat from the supply equipment, the operator gently pushes the movable baffle 3 upward and rotates it into the storage slot 11. Then, the cooling fan in the waterproof cover 1 starts to work and blows hot air towards the heat dissipation port 21. The heat dissipation port 21 is an inclined S-shaped channel. Its outer port is inclined downward by 10°-15° to prevent salt mist from directly invading, and its inner port is inclined upward by 10°-15° to follow the direction of the rising hot air. Two guide plates 221 are installed in the channel, with their arc-shaped concave surfaces facing outward. Salt mist is refluxed through the S-shaped bend and the guide plates 221. Some of the salt mist gathers into droplets at the first bend and is discharged. When not in operation or in severe sea conditions, the operator can reset the movable baffle 3 to close the heat sink 2.
[0040] When disassembling the heat sink 2, the worker can loosen the No. 2 bolt 24 and slide the heat sink 2 out along the mounting groove 14. When installing, the worker can slide the heat sink 2 in the opposite direction to the preset position and tighten the No. 2 bolt 24 to fix it.
[0041] When disassembling the guide plate 221, the staff can first unscrew the No. 1 bolt 23 to release the fixing between the connecting plate 22 and the heat sink 2, and slide the guide plate 221 along the mounting groove 211 so that one end of it is detached from the extension support groove 212 and then pulled out; when installing the new guide plate 221, insert the new guide plate 221 into the mounting groove 211 and slide it into the extension support groove 212, and finally tighten the No. 1 bolt 23 after the connecting plate 22 is aligned.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
