A new energy power waterproof connector for ships

Abstract

The present invention discloses a waterproof connector for new energy power of ships, belonging to the technical field of underwater power connectors. Through the waterproof kit and the pushing mechanism provided, in the case of low waterproof requirements, such as rain and snow weather, the protective shell can block the entry of moisture. At the same time, the heat generated during the high-power operation of the device can be effectively discharged through the heat dissipation holes of the heat dissipation member, thereby avoiding overheating caused by poor heat release. When encountering bad weather, the thermal conductive gel is sprayed out from the gel storage cavity through the discharge pipe and injected into the heat dissipation member to fill the joint between the free-end connector and the fixed-end connector, and form a thermal conductive gel layer under the restriction of the heat dissipation member to isolate moisture, forming an almost seamless heat conduction path between the free-end connector and the fixed-end connector, reducing the thermal resistance, improving the heat conduction efficiency, and cooperating with the heat dissipation member to quickly conduct the heat away to ensure that the device still maintains a normal temperature under high-load operation.

Description

Technical Field

[0001] The present invention relates to the technical field of marine power connectors, and particularly to a waterproof connector for new energy power of ships. Background Art

[0002] Power connectors are indispensable components in electrical and electronic equipment. They are mainly responsible for the circuit connection between cable lines and between cable lines and equipment. They play a prominent role in electrical control systems and power applications, capable of efficiently transmitting large currents and voltages to ensure the stable operation of electrical equipment.

[0003] Power connectors usually consist of two parts: a fixed-end connector and a free-end connector. The fixed-end connector is the passive connection part, installed on the panel and base, and the free-end electrical connector is the active connection part, which cooperates with the fixed-end electrical connector.

[0004] Compared with ordinary power connectors, marine power connectors need to use special sealing materials and designs to ensure safe and reliable operation on water. Usually, multiple waterproof channels are designed inside such connectors. Even if moisture penetrates the outer shell, it is difficult to contact the connector through the waterproof channels. Additionally, waterproof sealing tapes are used to isolate the contact between the housing and moisture, thereby achieving insulation and sealing protection between electrical component interfaces.

[0005] However, in the actual use process, excessive sealing or using inappropriate materials easily leads to ineffective heat dissipation. Especially when encountering bad weather, most of the equipment on the ship needs to operate at a continuous high power. Heat needs to be released through the waterproof channels and waterproof sealing tapes, and the heat dissipation system cannot dissipate the heat in time, which then causes the equipment to overheat. Therefore, a power connector is needed that can ensure good heat dissipation effect under low waterproof requirements, and at the same time can perform emergency waterproofing under high waterproof requirements. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that excessive sealing or using inappropriate materials easily leads to ineffective heat dissipation. Especially when encountering bad weather, most of the equipment on the ship needs to operate at a continuous high power. Heat needs to be released through the waterproof channels and waterproof sealing tapes, and the heat dissipation system cannot dissipate the heat in time, which then causes the equipment to overheat. And a waterproof connector for new energy power of ships is proposed that can ensure good heat dissipation effect under low waterproof requirements, and at the same time can perform emergency waterproofing under high waterproof requirements.

[0007] To achieve the above purpose, the present invention adopts the following technology: a waterproof connector for new energy power of ships

A waterproof kit is provided on the fixed - end connector. The waterproof kit includes a heat - dissipation part rotatably arranged on the surface of the fixed - end connector. The surface of the heat - dissipation part is provided with heat - dissipation holes and is located at the joint between the free - end connector and the fixed - end connector.

[0009] A pushing mechanism for emergency sealing is installed on the heat - dissipation part. The pushing mechanism includes a discharge pipe penetrating through the heat - dissipation part and a gel storage cavity connected to the discharge pipe. A movable piston is arranged inside the gel storage cavity, and a heat - conducting gel is stored between the piston and the discharge pipe.

[0010] When there is a risk of water ingress between the free - end connector and the fixed - end connector, the piston pushes the heat - conducting gel in the gel storage cavity to spray out from the discharge pipe, and the heat - conducting gel is injected into the heat - dissipation part to fill the joint between the free - end connector and the fixed - end connector to prevent water from entering.

[0024] The push rod pulls the sliding seat and the first guiding shaft to move and makes the first guiding shaft abut against the first guiding groove. Under the guidance of the first guiding groove, the sliding seat moves spirally along the track of the first guiding groove with the collar as the axis. The sliding seat drives the gel storage cavity and the discharge pipe to rotate through the push rod, so that the discharge pipe rotates under the restriction of the heat dissipation member.

[0032] As a further description of a marine new energy power waterproof connector of the above technology:

[0033] A connecting rod is connected to the end of the sliding rod, and a water tank is connected to the connecting rod. The water tank is annular and sleeved on the free-end connector, and a plurality of water drainage holes are opened at the bottom of the water tank.

[0034] In summary, due to the adoption of the above technology for a marine new energy power waterproof connector, the beneficial effects of the present invention are as follows:

[0035] 1. Through the provided waterproof kit and pushing mechanism, in the case of low waterproof requirements, such as rain and snow weather, the protective shell can block moisture from entering, and at the same time, the heat generated during the high-power operation of the device can be effectively discharged through the heat dissipation holes of the heat dissipation part, thus avoiding overheating caused by poor heat release; when encountering bad weather and there is a possibility that the free-end connector and the fixed-end connector are soaked in water or impacted by water waves, the thermal conductive gel is ejected from the gel storage cavity through the discharge pipe and injected into the heat dissipation part to fill the joint between the free-end connector and the fixed-end connector, and form a thermal conductive gel layer under the restriction of the heat dissipation part to isolate moisture. At the same time, an almost seamless heat conduction path is formed between the free-end connector and the fixed-end connector, reducing the thermal resistance, improving the heat conduction efficiency, and cooperating with the heat dissipation part to quickly conduct the heat out to ensure that the device still maintains a normal temperature under high-load operation;

[0036] 2. Through the provided steering mechanism, when the push rod moves under the pull of the spring elastic deformation recovery, the push rod pulls the sliding seat and the first guiding shaft to move and makes the first guiding shaft abut against the first guiding groove. Under the guidance of the first guiding groove, the sliding seat moves spirally along the track of the first guiding groove with the free-end connector as the axis. The sliding seat drives the gel storage cavity and the discharge pipe to rotate through the push rod. Since the heat dissipation part is rotatable, the discharge pipe can rotate under the restriction of the heat dissipation part. At this time, with the push of the piston, the thermal conductive gel is ejected from the discharge pipe, and the discharge pipe injects the thermal conductive gel into the heat dissipation part in a rotating state to form a thermal conductive gel ring with uniform thickness and fitting the joint between the free-end connector and the fixed-end connector;

[0037] 3. With the provided limit mechanism and water tank, in the case of low waterproof requirements, such as during rain or snow, after the rainwater enters the water tank, it is discharged through the water drainage holes. The gravity is not sufficient to pull the sliding rod through the connecting rod to release the restriction on the push rod, and the release of the thermal conductive gel will not be triggered. In the case of high waterproof requirements, such as when the rainfall is extremely heavy and cannot be quickly discharged through the water drainage holes, or when a large amount of water surges into the water tank due to the impact of water waves, the water tank quickly descends under the action of gravity and pulls the sliding rod through the connecting rod to release the restriction on the push rod, triggering the release of the thermal conductive gel for emergency sealing.

[0061] Next, the technical solution of a marine new energy power waterproof connector in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] In order to solve the problem that excessive sealing or using inappropriate materials is likely to cause ineffective heat dissipation. Especially when encountering bad weather, most of the equipment on the ship needs to run at a continuous high power, and the heat needs to be released through the waterproof channel and the waterproof sealing tape, and the heat dissipation system cannot dissipate the heat in time, thus causing the problem of overheating of the equipment. The present invention proposes a marine new energy power waterproof connector, as Figure 1 - Figure 15 shown:

[0063] It includes a fixed - end connector 20 installed vertically with its port facing downwards and a free - end connector 10 installed on the fixed - end connector 20. Compared with horizontal installation, the advantage of vertical installation is that, by utilizing the action of gravity, the water accumulated in the fixed - end connector 20 can be more easily drained, thereby keeping the fixed - end connector 20 dry. A waterproof kit 30 for waterproofing is provided on the fixed - end connector 20, such as Figure 1 、 Figure 2 and Figure 5 shown. The waterproof kit 30 includes a heat - dissipating part 32 rotatably arranged on the surface of the fixed - end connector 20 and a protective shell 33. The inner wall of the protective shell 33 is provided with threads, and the surface of the free - end connector 10 is provided with a thread groove that meshes with the drain hole 34, as Figure 4 shown. After the free - end connector 10 is connected to the fixed - end connector 20, the protective shell 33 is rotated to connect and reinforce the free - end connector 10. Heat - dissipating holes are provided on the surface of the heat - dissipating part 32 and are located at the joint of the free - end connector 10 and the fixed - end connector 20;

[0064] The waterproof kit 30 also includes a rotating part 31 rotatably arranged on the fixed - end connector 20. The heat - dissipating part 32 is rotatably connected to the rotating part 31 and the protective shell 33 is rotatably connected to the heat - dissipating part 32. After the free - end connector 10 is connected to the fixed - end connector 20, the protective shell 33 is sleeved on the surface of the free - end connector 10, and then the protective shell 33 is rotated so that the protective shell 33 rotates under the restriction of the heat - dissipating part 32 until the protective shell 33 is connected to the free - end connector 10 through threads and cannot rotate. At this time, the heat - dissipating part 32 can rotate between the rotating part 31 and the protective shell 33. In the case of low waterproof requirements, such as in rainy and snowy weather, the protective shell 33 can block moisture from entering, and at the same time, the heat generated during high - power operation of the device can be effectively discharged through the heat - dissipating holes of the heat - dissipating part 32, thus avoiding overheating caused by poor heat release;

[0065] At the same time, as Figure 2 and Figure 5 shown, a number of drain holes 34 are equidistantly and circularly arranged on the surface of the protective shell 33. The top of the drain hole 34 is opened on the inner wall of the protective shell 33 and the bottom is through - hole - shaped. The hole wall is inclined to block the direct influx of moisture. Through this design, the water molecules that enter through the heat - dissipating holes of the heat - dissipating part 32 can be discharged from the protective shell 33 through the drain holes 34 after condensation, avoiding water accumulation. While preventing rainwater from entering the protective shell 33 through the drain holes 34, the water surging into the drain holes 34 from bottom to top can also be blocked by the inclined inner wall, and the moisture cannot easily enter.

[0066] When encountering bad weather and there is a possibility that the free - end connector 10 and the fixed - end connector 20 are soaked in water or impacted by water waves, and the waterproof requirement increases, sealing can be carried out through the pushing mechanism 40, such as Figure 3 、 Figures 6 - 8As shown, a pushing mechanism 40 for emergency sealing is installed on the heat dissipation part 32. The pushing mechanism 40 includes a discharge pipe 44 penetrating through the heat dissipation part 32 and a gel storage cavity 41 connected to the discharge pipe 44. A movable piston 42 is arranged inside the gel storage cavity 41, and a heat-conducting gel is stored between the piston 42 and the discharge pipe 44;

[0067] The pushing mechanism 40 further includes a push rod 43 penetrating through the middle of the gel storage cavity 41 and connected to the piston 42, and a material inlet hole 411 opened on the gel storage cavity 41. The heat-conducting gel is injected into the gel storage cavity 41 through the material inlet hole 411;

[0068] The gel storage cavity 41 is installed through an installation hole 331 and a positioning frame 332 arranged on the protective shell 33. As Figure 5 and Figure 6 shown, by pulling the push rod 43, the piston 42 is moved to the end of the gel storage cavity 41 away from the discharge pipe 44, and the material inlet hole 411 is opened for injecting the heat-conducting gel. After the injection is completed, the gel storage cavity 41 is placed on the installation hole 331, and then the positioning frame 332 is connected to the installation hole 331 with bolts to fix the gel storage cavity 41, and the installation of the gel storage cavity 41 is completed;

[0069] When there is a risk of water immersion in the free-end connector 10 and the fixed-end connector 20, by pushing the push rod 43, the push rod 43 drives the piston 42 to move inside the gel storage cavity 41 to shorten the distance from the discharge pipe 44. As the space inside the gel storage cavity 41 is compressed, the heat-conducting gel is ejected from the gel storage cavity 41 through the discharge pipe 44 and injected into the heat dissipation part 32 to fill the joint between the free-end connector 10 and the fixed-end connector 20, and a heat-conducting gel layer is formed under the restriction of the heat dissipation part 32 to isolate moisture. At the same time, an almost seamless heat conduction path is formed between the free-end connector 10 and the fixed-end connector 20, reducing the thermal resistance, improving the heat conduction efficiency, and cooperating with the heat dissipation part 32 to quickly conduct the heat out, ensuring that the equipment still maintains a normal temperature under high-load operation. It should be noted that the thermal conductivity of the hydrophobic heat-conducting gel may be affected after contacting with water, so the hydrophilic heat-conducting gel is preferably selected.

[0070] In order to enable the push rod 43 to move by itself, an installation cavity 431 is opened in the middle of the push rod 43, and a positioning mechanism 50 for controlling the movement of the push rod 43 is arranged in the installation cavity 431. As Figure 7 and Figure 8 shown;

[0071] The positioning mechanism 50 includes a clamping groove 51 provided in the middle of the gel storage cavity 41 and a positioning block 52 embedded in the clamping groove 51. A convex block connected to the clamping groove 51 is provided on the positioning block 52. A straight groove for the convex block to penetrate is opened on the surface of the installation cavity 431. When the push rod 43 moves, the straight groove opened on the installation cavity 431 moves along the surface of the convex block;

[0072] The other end of a spring 53 is connected to the inner wall of the installation cavity 431, and one end of the spring 53 is connected to the positioning block 52. Through this design, the spring 53 is arranged inside the installation cavity 431, and the installation cavity 431 can protect the spring 53, so as to achieve the purpose of slowing down the rusting speed of the spring 53;

[0073] By pulling the push rod 43, the push rod 43 pulls the piston 42 to move inside the gel storage cavity 41 under the limitation of the clamping groove 51 and the positioning block 52. As the distance between the positioning block 52 and the push rod 43 extends, the spring 53 is pulled and elastically deformed. At this time, if the push rod 43 is released, the push rod 43 can push the piston 42 to move by itself under the pulling of the elastic deformation recovery of the spring 53, so that the heat-conducting gel in the gel storage cavity 41 is ejected.

[0074] Furthermore, in order to enable the heat-conducting gel to evenly cover the joint between the free-end connector 10 and the fixed-end connector 20, form an effective waterproof layer, and at the same time avoid too much heat-conducting gel from hindering heat dissipation, as Figure 4 、 Figure 9 and Figure 10 shown, a steering mechanism 60 is connected to the end of the push rod 43. The steering mechanism 60 includes a sliding seat 61 provided at the end of the push rod 43 and a collar 63 installed on the surface of the free-end connector 10. A first guiding groove 64 is opened on the collar 63, and a first guiding shaft 62 that cooperates with the first guiding groove 64 is provided on the sliding seat 61;

[0075] When the push rod 43 moves under the pulling of the elastic deformation recovery of the spring 53, the push rod 43 pulls the sliding seat 61 and the first guiding shaft 62 to move and makes the first guiding shaft 62 abut against the first guiding groove 64. Under the guidance of the first guiding groove 64, the sliding seat 61 moves in a spiral shape along the track of the first guiding groove 64 with the free-end connector 10 as the axis. The sliding seat 61 drives the gel storage cavity 41 and the discharge pipe 44 to rotate through the push rod 43. Since the heat dissipation member 32 is rotatable, the discharge pipe 44 can rotate under the limitation of the heat dissipation member 32. At this time, as the piston 42 pushes, the heat-conducting gel is ejected from the discharge pipe 44, and the discharge pipe 44 injects the heat-conducting gel into the heat dissipation member 32 in a rotating state, forming a heat-conducting gel ring with uniform thickness and fitting the joint between the free-end connector 10 and the fixed-end connector 20;

[0076] Preferably, two pushing mechanisms 40 are provided symmetrically. Sliding seats 61 and first guiding shafts 62 are provided on both push rods 43. Two first guiding grooves 64 are formed on the collar 63. The number of turns of the first guiding groove 64 from the starting point to the ending point is one turn. The distance between the starting point and the ending point of the first guiding groove 64 is the same as the maximum distance that the piston 42 can move inside the gel storage cavity 41. After the piston 42 finishes pushing, the first guiding shaft 62 moves to the ending point of the first guiding groove 64. During this process, the two discharge pipes 44 rotate one week respectively and inject heat-conducting gel. Through two injections, it is ensured that the thickness of the heat-conducting gel ring is uniform and fitting.

[0077] After pulling the push rod 43 to a specified position and the first guiding shaft 62 reaches the starting point of the first guiding groove 64, it is necessary to limit the position of the push rod 43 and realize automatic unlocking when high waterproof requirements are needed. The position of the push rod 43 is locked by a limiting mechanism 70, as Figure 7 , Figure 8 , Figures 11 - 14 shown. The limiting mechanism 70 includes a mounting seat 75 rotatably arranged inside the sliding seat 61, a rotating shaft 71 rotatably arranged in the middle of the mounting seat 75 and passing through the mounting cavity 431 and the middle of the positioning block 52, and a limiting groove 74 formed inside the positioning block 52;

[0078] The limiting groove 74 includes a straight groove part and an arc groove part that communicate with each other. A limiting block 72 cooperating with the limiting groove 74 is arranged at the end of the rotating shaft 71. After pulling the push rod 43 to the specified position, the rotating shaft 71 will drive the limiting block 72 to insert into the straight groove part of the limiting groove 74. At this time, rotate the rotating shaft 71 again to drive the limiting block 72 to rotate by the rotating shaft 71, and the limiting block 72 enters the arc groove part. Under the limitation of the arc groove part, the limiting block 72 cannot move. When the limiting block 72 is restricted, the push rod 43 cannot move, so as to achieve the purpose of restricting the push rod 43 and preventing it from resetting itself;

[0079] At the same time, the limiting mechanism 70 further includes a spiral second guiding groove 73 formed on the surface of the rotating shaft 71 and a sliding rod 76 nested on the mounting seat 75. A second guiding shaft 77 cooperating with the second guiding groove 73 is arranged inside the sliding rod 76. When it is necessary to release the restriction on the position of the push rod 43, pull the sliding rod 76 by an external force, so that the sliding rod 76 moves under the restriction of the second guiding shaft 77 and drives the second guiding shaft 77 to abut against the second guiding groove 73 when moving. Under the pushing of the second guiding shaft 77 and the guiding of the second guiding groove 73, the rotating shaft 71 rotates in the middle of the mounting seat 75, so that the rotating shaft 71 can drive the limiting block 72 to rotate out of the arc groove part of the limiting groove 74, and the restriction of the limiting groove 74 on the limiting block 72 is released;

[0080] It should be noted that during the process of inserting the limiting block 72 into the limiting groove 74, the sliding rod 76 needs to be manually pulled first, so that the rotating shaft 71 drives the limiting block 72 to rotate to an angle that can be inserted into the straight groove part of the limiting groove 74. After the push rod 43 is pulled to the specified position, the sliding rod 76 is pushed to reset, so that the sliding rod 76 cooperates with the second guiding shaft 77 to drive the rotating shaft 71 to rotate.

[0081] In order to control whether the sliding rod 76 is pulled by an external force according to the waterproof requirements of the free end connector 10 and the fixed end connector 20, a connecting rod 81 is connected to the end of the sliding rod 76, and a water tank 82 is connected to the connecting rod 81. The water tank 82 is annular and sleeved on the free end connector 10, and a number of water drainage holes are opened at the bottom of the water tank 82;

[0082] In the case of low waterproof requirements, such as in rainy or snowy weather, after the rain enters the water tank 82, it is discharged through the water drainage holes, and the gravity is not enough to pull the sliding rod 76 through the connecting rod 81 to release the restriction on the push rod 43, and the release of the thermal conductive gel will not be triggered;

[0083] In the case of high waterproof requirements, such as when the rain volume is extremely large and cannot be quickly discharged from the water tank 82 through the water drainage holes, or when a large amount of water surges into the water tank 82 due to being slapped by water waves, the water tank 82 quickly descends under the action of gravity and pulls the sliding rod 76 through the connecting rod 81 to release the restriction on the push rod 43, triggering the release of the thermal conductive gel for emergency sealing;

[0084] Compared with directly coating the thermal conductive gel on the free end connector 10 and the fixed end connector 20, the advantage of coating the thermal conductive gel when the waterproof requirement is high is that it can provide additional protection for the free end connector 10 and the fixed end connector 20 under harsh conditions, and at the same time avoid the problems of aging, cracking or falling off of the pre-coated thermal conductive gel after long-term use, which affects the sealing effect. Without shortening the service life of the thermal conductive gel, its stability and reliability in dealing with high waterproof requirements are increased. After the waterproof requirement is reduced, the staff can regularly remove the thermal conductive gel ring and add new thermal conductive gel to the gel storage cavity 41.

[0085] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
