Description

Technical Field

[0001] This invention relates to the technical field of UPS power control boxes for marine medium-speed engines, and more particularly to a UPS power control box for marine heavy-duty medium-speed engines. Background Technology

[0002] Large cargo ships use engines that burn heavy oil. Inland waterway cargo ships are generally driven by medium-speed engines, which are powered by generators installed on board. In order to ensure the normal operation of the medium-speed engines in the event of generator failure, UPS power supplies are usually installed on board as backup power for the medium-speed engines.

[0003] Typically, a UPS power control box consists of a UPS main unit, marine batteries, a battery rack, and functional software. During operation, the inverter on the marine battery converts the battery's output voltage into the operating voltage required for medium-speed operation. The heat generated during battery charging and discharging is cooled by airflow through ventilation holes on the surface of the control box. However, during ship navigation, moisture from the water can also enter the UPS power control box through these ventilation holes, causing extreme moisture on the positive and negative ends of the marine batteries and inverters inside the UPS power control box. This can easily lead to leakage, damage to the marine batteries and inverters, and affect the safe navigation of the ship. Summary of the Invention

[0004] The purpose of this invention is to reduce the impact of the above-mentioned situations and to provide a marine heavy-duty medium-speed engine UPS power control box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a marine heavy-duty medium-speed UPS power control box, comprising a UPS power control box body installed on a ship, wherein the box body is provided with several boxes for sealing and storing marine batteries, and a perforated rear cover plate for ventilation and fitting the opening surface of the box body is hinged to the side of the box body facing the box opening. Adjacent boxes and boxes are connected by several connecting shafts with gaps. One side of the box body is connected to an air inlet pipe, and a fan for supplying air into the box body is provided in the air inlet pipe. An air guide plate is rotatably provided on the inner wall of the box body to guide the air towards the box body. A transmission mechanism connecting the fan and the air guide plate is provided in the air inlet pipe, and the transmission mechanism converts the circular motion of the fan into the reciprocating oscillating motion of the air guide plate.

[0006] Preferably, the transmission mechanism includes a reducer installed inside the air inlet pipe, the input shaft of the reducer is connected to the end face of the fan blade shaft, and the output shaft of the reducer is fixed with an eccentric plate. A U-shaped mounting seat is rotatably mounted on the side of the eccentric plate facing away from the reducer. A connecting block is rotatably mounted on the inner wall of the U-shaped mounting seat. A U-shaped connecting seat is rotatably mounted on the air guide plate and is sleeved with the connecting block and rotates relative to it.

[0007] Preferably, the top of the inner sidewalls of the box body is provided with two vertical guide rails. The bottom surface of the two guide rails is fixed with a baffle that fits the top edge of the side of the marine battery. A pressure block that moves up and down and fits the top side of the marine battery is sleeved on the guide rail. A long bolt is provided through the pressure block and the two guide rails. The pressure block is provided with a pressure rubber pad that fits the top surface of the marine battery.

[0008] Preferably, the enclosure is provided with a conduit that communicates with the interior of the enclosure and is used for wires to pass through. A front cover is hinged to the side of the enclosure facing away from the opening. A socket for plugging into a medium-speed engine is provided on the front cover. One end of the conduit is attached to the surface of the socket. The socket is electrically connected to the positive and negative terminals of several marine batteries.

[0009] Preferably, each socket of the socket is equipped with a detachable waterproof cover that is threadedly connected to the socket. The waterproof cover is fitted onto the plug that mates with the socket, and the waterproof cover is fitted with an internal threaded ring that is threadedly connected. The waterproof cover is composed of two transparent shells that are used together.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The enclosure and rear cover ensure that the marine battery is stored in a sealed environment, preventing moisture corrosion. During ship operation, air containing moisture is blown into the enclosure by a fan, and the air guide plate swings under the action of the transmission mechanism. The reciprocating swing of the air guide plate ensures that the air covers the entire enclosure, avoiding ventilation dead zones. The air flows along the gaps between the enclosures and finally blows out through the perforations of the rear cover plate. During the airflow, the surface temperature of the enclosure is carried away, and the temperature inside the enclosure is reduced through heat conduction. This reduces the temperature of the heated marine battery, thus protecting the positive and negative terminals of the marine battery while cooling it down.

[0012] 2. The conduit is designed to facilitate the insertion of wires from the socket into the box and connect to the marine battery inside. This allows for charging of the marine battery through a specific socket, while also enabling power supply to the medium-speed engine by connecting to other sockets on the socket. The internal threaded ring allows the waterproof cover to be secured to the plug, ensuring waterproofing near the socket socket. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] Please see Figure 1-5This invention provides a technical solution: a marine heavy-duty medium-speed engine UPS power control box, including a UPS power control box body 1 installed on a ship. The body 1 contains several boxes 8 for sealed storage of marine batteries 13. A perforated rear cover 2, for ventilation and conforming to the opening of the box 8, is hinged to the side of the body 1 facing the opening of the box 8. Adjacent boxes 8 and the boxes 8 are connected to the body 1 by several connecting shafts 9. An air inlet pipe 12 is connected to one side of the body 1. A fan 18 is installed in the air inlet pipe 12 to supply air into the body 1, and the inner wall of the body 1 is rotatable to guide the air towards the boxes 8. The air guide plate 4 and the air inlet pipe 12 are equipped with a transmission mechanism that connects the fan 18 and the air guide plate 4. The transmission mechanism converts the circular motion of the fan 18 into the reciprocating oscillating motion of the air guide plate 4. The transmission mechanism includes a reducer 22 installed in the air inlet pipe 12. The input shaft of the reducer 22 is connected to the end face of the fan blade shaft of the fan 18. The output shaft of the reducer 22 is fixed with an eccentric plate 23. A U-shaped mounting seat 14 is rotatably mounted on the side of the eccentric plate 23 facing away from the reducer 22. A connecting block 3 is rotatably mounted on the inner wall of the U-shaped mounting seat 14. A U-shaped connecting seat 21 is rotatably mounted on the air guide plate 4 and is sleeved with the connecting block 3 and rotates relative to it.

[0023] The effects achieved in this embodiment are as follows: the surfaces of both the housing 1 and the box 8 are made of metal and coated with anti-corrosion paint, ensuring heat conduction while preventing surface corrosion due to moisture. Several boxes 8 are stacked inside the housing 1, and when the rear cover 2 is closed, the boxes 8 are sealed, preventing the marine battery 13 from contacting moisture in the air, thus ensuring that the positive and negative terminals of the marine battery 13 do not rust. In actual use, the marine battery 13 is used in conjunction with an inverter. The connecting shaft 9 ensures that gaps are formed between the box 8 and the inner wall of the housing 1, as well as between the boxes 8 themselves. During heat dissipation, air enters through the air inlet pipe 12 and, through the action of the air guide plate 4, the airflow is directly blown onto the box 8, reducing the surface temperature of the box 8. Heat is then blown out of the housing 1 from the rear cover 2. The reducer 22 is a planetary reducer and works in conjunction with the fan 18. The eccentric plate 23, which serves as the power source, operates on a similar principle to the eccentric wheel. Specifically, the U-shaped mounting base 14 is misaligned with the output shaft of the reducer 22. When the reducer 22 operates, the U-shaped mounting base 14 revolves around it. Meanwhile, the connecting block 3, rotatably mounted inside the U-shaped mounting base 14, is simultaneously connected to the U-shaped connecting seat 21 on the air guide plate 4. Therefore, when the eccentric plate 23 rotates, the U-shaped mounting base 14 rotates accordingly because of the connection between the connecting block 3 and the U-shaped connecting seat 21. During the rotation of the eccentric plate 23, the position of the U-shaped mounting base 14 continuously adjusts, causing one end of the connecting block 3 to perform a circular motion, while the other end, connected to the U-shaped connecting seat 21, performs a linear reciprocating motion, simultaneously causing the U-shaped connecting seat 21 to rotate accordingly. When the other end of the connecting block 3 performs a linear reciprocating motion, because the air guide plate 4 is rotatably connected to the housing 1, it causes the air guide plate 4 to swing back and forth. During this swinging motion, the connecting block 3 rotates relative to the U-shaped connecting seat 21 and the U-shaped mounting base 14.

[0024] Example 2

[0025] Please see Figure 1-5 Two vertical guide rails 16 are provided on the top of the opposite inner side walls of the box body 8. A baffle 15 that fits the top edge of the side of the marine battery 13 is fixed to the bottom surface of the two guide rails 16. A pressure block 11 that moves up and down and fits the top side of the marine battery 13 is fitted on the guide rails 16. A long bolt 17 is provided between the pressure block 11 and the two guide rails 16. An L-shaped plate 18 is fixed on the pressure block 11. A pressure rubber pad 19 that fits the top surface of the marine battery 13 is provided inside the L-shaped plate 18.

[0026] As a further optimization of the present invention, the effect achieved by the embodiment is as follows: the baffle 15 and the pressure block 11, by contacting the side and top surface of the marine battery 13, can fix the position of the marine battery 13 in the box 8, preventing the marine battery 13 from shaking in the box 8 when the ship is rocking. The marine battery 13 in the present invention is a 12V 24AH battery, and the marine battery 13 is used in conjunction with the UPS power supply battery EPS inverter. The long bolt 17 passes through the pressure block 11 and the guide rail 16 to ensure that the relative position of the pressure block 11 and the guide rail 16 is fixed. When the rear cover 2 is closed, the long bolt 17 always partially passes through the guide rail 16 and the pressure block 11 during the shaking process. The bottom surface of the pressure rubber pad 19 has two arc-shaped grooves, which facilitate pressing the wires connecting the positive and negative terminals of the inverter. By using the torque of the wire itself, the position of the wire is fixed, thus fixing the connection point between the wire and the positive and negative terminals of the inverter and ensuring the stability of the connection.

[0027] Example 3

[0028] Please see Figure 1-5 The housing 1 has a conduit 7 that communicates with the interior of the box 8 and is used for wires to pass through. The side of the housing 1 facing away from the opening of the box 8 is hinged to a front cover 5. The front cover 5 is provided with a socket 6 that is plugged into the medium speed engine plug. One end of the conduit 7 is attached to the surface of the socket 6. The socket 6 is electrically connected to the positive and negative terminals of several marine batteries 13. Each socket 6 is equipped with a detachable waterproof cover 20 that is threaded to the socket 6. The waterproof cover 20 is fitted onto the plug that mates with the socket. The waterproof cover 20 is fitted with a threaded internal thread ring 10. The waterproof cover 20 is composed of two transparent shells that are used together.

[0029] As a further optimization of the present invention, the embodiment achieves the following effect: The socket 6 is provided with several sockets, and two wires extend from the socket 6, the two wires being connected to the positive and negative terminals of the marine battery 13 respectively. The sockets on the socket 6 are divided into two parts: one part is used to charge the marine battery 13 through the socket 6, and the other part is used to connect to the plug on the medium-speed engine to supply power to the medium-speed engine. The conduit 7 facilitates the storage of the wires connecting the socket 6 and the marine battery 13, and the conduit... The conduit 7 is in contact with the surface of the socket 6, ensuring the airtightness of the inside of the conduit 7 and preventing moisture from entering the conduit 7. The two transparent shells that make up the waterproof cover 20 have sealing gaskets on their mating surfaces to ensure the airtightness of the connection surface when the waterproof cover 20 clamps the plug and wire. The internal threaded ring 10 facilitates the stability of the assembled waterproof cover 20. The threaded connection between the waterproof cover 20 and the socket 6 ensures that the relative positions of the waterproof cover 20 and the socket 6 are fixed and that external moisture will not come into contact with the plug and socket 6, thus achieving protection.

[0030] The method of using this invention is as follows: Open the rear cover 2, slide the marine battery 13 into the box 8, and let the multiple wires extending from the socket 6 pass through the conduit 7 into each box 8. Close the front cover 5, and connect the multiple wires to the positive and negative terminals of the inverter on the marine battery 13. Then, the pressure block 11 is lowered, and the wires connected to the inverter are pressed down by the pressure rubber pad 19 on the pressure block 11. Then, close the rear cover 2. During the operation of the ship, the cold and humid air from the outside enters the box 1 through the air inlet pipe 12 under the action of the fan 18. Under the reciprocating swing of the air guide plate 4, the air direction is continuously oscillating and covering the entire box 8. The air is blown out through the gaps around the box 8 and finally through the hollow of the rear cover 2. During the air flow, the surface temperature of the box 8 is reduced, and the temperature inside the box 8 is reduced under the action of heat conduction. This reduces the temperature of the heated marine battery 13, and at the same time, the positive and negative terminals of the marine battery 13 are protected.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
