Description

Technical Field

[0001] This invention relates to the field of shipboard equipment, and more particularly to a shipboard power distribution device. Background Technology

[0002] On ships, electrical distribution boxes are essential equipment, serving as the ship's electrical hub. Their primary function is to distribute power, distributing the voltage from the transformer to various electrical devices. Because distribution boxes contain numerous wires, current methods typically use cable ties to bundle them together. However, this method makes it difficult to identify the function of the wires during maintenance, hindering repairs. Furthermore, bundled wires impede heat dissipation, increasing the risk of overheating and fire. Summary of the Invention

[0003] The purpose of this invention is to provide a marine power distribution device with a simple structure that can classify and bundle different wires.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A marine power distribution device is provided, including a distribution box. The distribution box contains electrical components and a wiring assembly. The electrical components include terminals for connecting to the power cord of an external electrical device. The wiring assembly includes a drive unit and multiple sets of wire clamps. Each set of wire clamps includes two opposing clamps, with a limiting space between the two clamps for restricting the power cord. The drive unit is connected to all the wire clamps via a linkage, and the drive unit can simultaneously drive two clamps in each set of wire clamps to move relative to or away from each other to simultaneously adjust the limiting space.

[0006] As a preferred embodiment of a marine power distribution device, the linkage includes a fixed base with opposing first and second sides. A linkage plate is slidably disposed on the first side. A driving member is connected to the linkage plate and can drive the linkage plate to move relative to the fixed base in a first direction. A limiting part is provided on the second side, and a clamping plate is slidably disposed on the limiting part. The clamping plate can move relative to the fixed base in a second direction. The first and second directions are perpendicular.

[0007] The linkage plate is provided with multiple sets of strip holes spaced apart along the second direction. Each set of strip holes includes two inclined strip holes symmetrically arranged along the first direction, and the length direction of the strip holes is set at an acute angle to the first direction. Each clamping plate is provided with a connecting part, and the number of connecting parts corresponds one-to-one with the number of strip holes. Each connecting part is inserted into one of the strip holes. The movement of the linkage plate can simultaneously drive two clamping plates in each set of clamping components to move relative to or away from each other.

[0008] As a preferred embodiment of a marine power distribution device, one of the first side and the linkage plate is provided with a first slide rail extending along the first direction, and the other of the first side and the linkage plate is provided with a sliding part that cooperates with the first slide rail, and the sliding part is slidably disposed on the first slide rail.

[0009] As a preferred embodiment of a marine power distribution device, the driving component is a first elastic component. A retractable guide rod is connected between the linkage plate and the inner wall of the distribution box. The first elastic component is sleeved on the outside of the guide rod and abuts against the linkage plate and the inner wall of the distribution box. The first elastic component can drive the linkage plate to move and cause the two clamping plates of each set of clamping components to have a relative movement tendency.

[0010] As a preferred embodiment of marine power distribution equipment, each set of clamping members has concave arc-shaped surfaces on the opposite sides of the two clamping plates, and elastic gaskets are provided on the arc-shaped surfaces.

[0011] As a preferred embodiment of a marine power distribution device, the power distribution box is equipped with a heat dissipation assembly, which includes a dehumidifier, a liquid cooling plate, and a condenser. The dehumidifier includes a housing and an adsorbent disposed within the housing. The adsorbent is used to absorb moisture from the air inside the power distribution box and convert it into liquid water, which is collected within the housing. The electrical components are mounted on the liquid cooling plate, which is equipped with cooling pipes. The inlet of the cooling pipes is connected to the outlet of the housing, and the outlet of the cooling pipes is connected in sequence to the condenser and the inlet of the housing. The liquid water can circulate between the housing and the cooling pipes.

[0012] As a preferred embodiment of marine power distribution equipment, the heat dissipation component further includes a fan. The distribution box has an air inlet and an air outlet on its wall. The fan is installed at the air inlet or the air outlet and enables the outside air to circulate between the outside and inside of the distribution box.

[0013] As a preferred embodiment of marine power distribution equipment, the liquid cooling plate divides the distribution box into a first chamber and a second chamber, with the electrical components located in the first chamber and the heat dissipation assembly located in the second chamber.

[0014] As a preferred embodiment of marine power distribution equipment, the power distribution box is also equipped with a lighting assembly, which includes a lighting lamp and two conductive plates, one of which is connected to a power source and the other of which is connected to the lighting lamp.

[0015] The distribution box includes a box body with an opening and a cover that closes to the opening of the box body. The lighting lamp is disposed inside the box body. A mounting groove is provided around the periphery of the opening. Two conductive sheets are installed in the mounting groove. A second elastic member is also provided in the mounting groove. The second elastic member can drive the two conductive sheets to move closer together to maintain contact. A driving part is provided on the cover. When the cover is closed on the box body, the driving part is inserted into the mounting groove and drives the two conductive sheets to separate.

[0016] As a preferred embodiment of marine power distribution equipment, the wiring terminals include a first terminal module and a second terminal module. The first terminal module and the second terminal module are respectively connected to the power supply through a circuit breaker, and the circuit breaker is covered with an insulating protective cover.

[0017] The distribution box is equipped with an insulating partition that separates the first terminal module and the second terminal module. The distribution box is provided with a first wire hole and a second wire hole. The power cord can pass through the first wire hole to connect to the first terminal module or through the second wire hole to connect to the second terminal module.

[0018] The beneficial effects of this invention are as follows: by cooperating with a driving component and a linkage component, multiple wire clamping components are linked together, so as to simultaneously drive the two clamping plates in each group of wire clamping components to move relative to or away from each other, thereby adjusting the limiting space to clamp multiple power lines at the same time, eliminating the need to bundle each wire individually, which helps to improve wire bundling efficiency. At the same time, the adjustable limiting space can also be used to bundle wires of different sizes, with good compatibility. Moreover, the linkage control method also helps to reduce the number of parts and reduce costs. Attached Figure Description

Detailed Implementation

[0027] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail 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.

[0028] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] On ships, electrical distribution boxes are essential equipment, serving as the ship's electrical hub. Their primary function is to distribute power, distributing the voltage from the transformer to various electrical devices. Because distribution boxes contain numerous wires, current methods typically use cable ties to bundle them together. However, this method makes it difficult to identify the function of the wires during maintenance, hindering repairs. Furthermore, bundled wires impede heat dissipation, increasing the risk of overheating and fire.

[0030] like Figures 1 to 3 As shown, the present invention provides a marine power distribution device, including a power distribution box 1. The power distribution box 1 is provided with electrical components and a wire harness assembly 3. The electrical components include terminals 2, which are used to connect to the power cord of external electrical equipment to provide power to the external electrical equipment. The wire harness assembly 3 includes a drive member 32 and multiple sets of wire clamps 31. Each set of wire clamps 31 includes two opposing clamps 311. A limiting space for limiting the power cord is formed between the two clamps 311. The limiting space of each set of wire clamps 31 can be used to clamp one power cord. Multiple sets of wire clamps 31 clamp multiple power cords respectively to classify and bundle the wires, so as to distinguish different types of power cords. Moreover, individual wire bundling helps the power cord to dissipate heat.

[0031] The driving component 32 is connected to all the clamping components 31 via a linkage component. The driving component 32 can simultaneously drive two clamping plates 311 in each set of clamping components 31 to move relative to or away from each other, thereby adjusting the limiting space at the same time. Understandably, the power cord of an external electrical device may consist of one or more wires, such as a power cord connected to a terminal block, including separately configured live, neutral, and ground wires. Therefore, multiple sets of clamping components 31 are needed to clamp different wires respectively. This design achieves the linkage of multiple clamping components 31 through the cooperation of a driving component 32 and a linkage component, enabling the two clamping plates 311 in each set of clamping components 31 to move relative to or away from each other, thereby adjusting the limiting space and clamping multiple wires simultaneously. This eliminates the need for individual wire bundling, improving bundling efficiency. Furthermore, the adjustable limiting space allows for bundling of wires of different sizes, offering good compatibility. It also helps reduce the number of parts and lower costs.

[0032] In this embodiment, as Figure 2 and Figure 3As shown, the linkage includes a fixed base 33, which has a first side and a second side opposite to each other along the z-direction. A linkage plate 34 is slidably disposed on the first side. A driving member 32 is connected to the linkage plate 34. The driving member 32 can drive the linkage plate 34 to move relative to the fixed base 33 along the first direction (x direction in the figure). A limiting part 35 is provided on the second side. A clamping plate 311 is slidably disposed on the limiting part 35. The clamping plate 311 can move relative to the fixed base 33 along the second direction (y direction in the figure). It should be noted that the x-direction, y-direction and z-direction in the figure are perpendicular.

[0033] The linkage plate 34 is provided with multiple sets of strip holes 341 at intervals along the second direction. Each set of strip holes 341 includes two inclined strip holes 341 symmetrically arranged along the first direction. The length direction of the strip holes 341 is set at an acute angle to the first direction. In other words, the two strip holes 341 in each set of strip holes 341 form an "eight" shaped structure. Each clamping plate 311 is provided with a connecting part 3111. The number of connecting parts 3111 corresponds one-to-one with the number of strip holes 341. Each connecting part 3111 is inserted into a strip hole 341. The movement of the linkage plate 34 can simultaneously drive the two clamping plates 311 in each set of clamping parts 31 to move relative to each other or away from each other.

[0034] Understandably, each set of strip holes 341 has a contracting end and an expanding end opposite each other along the first direction. When the driving member 32 drives the linkage plate 34 to move from the expanding end to the contracting end along the first direction, the hole wall of the strip hole 341 will abut against the connecting part 3111, so as to drive the connecting parts 3111 of the two clamping plates 311 to move relative to the strip hole 341 and gradually approach each other, thereby driving all the clamping plates 311 to move closer to each other relative to the limiting part 35 along the second direction, so as to realize that the two clamping plates 311 of the clamping member 31 approach each other to clamp the power cord.

[0035] Specifically, one of the first side surface and the linkage plate 34 is provided with a first slide rail 36 extending along a first direction, and the other of the first side surface and the linkage plate 34 is provided with a sliding part 37 that cooperates with the first slide rail 36. The sliding part 37 is slidably disposed on the first slide rail 36. For example, the first side surface is provided with the first slide rail 36, and the sliding part 37 is a groove on the linkage plate 34. The linkage plate 34 slides with the first slide rail 36 through the groove to restrict the linkage plate 34 to move only along the first direction and prevent the linkage plate 34 from deviating.

[0036] For example, the limiting part 35 is the second slide rail, and the clamping plate 311 is provided with a slider. The slider slides in cooperation with the second slide rail, thereby restricting the clamping plate 311 to move only in the second direction and preventing the clamping plate 311 from deviating.

[0037] Optionally, the driving component 32 is a first elastic element, which is disposed between the inner wall of the distribution box 1 and the linkage plate 34. The first elastic element can drive the linkage plate 34 to move, and cause the two clamping plates 311 of each set of clamping components 31 to have a tendency to move relative to each other. For example, the expanding end of each set of strip holes 341 is closer to the first elastic element, and the contracting end of each set of strip holes 341 is farther away from the first elastic element. The first elastic element has a tendency to drive the linkage plate 34 to move along a first direction from the expanding end of each set of strip holes 341 toward the contracting end of each set of strip holes 341. This design can use the elastic force of the first elastic element to keep each set of clamping components 31 clamping the power cord, so as to prevent the power cord from detaching from the clamping component 31. When disconnecting the wire, the linkage plate 34 can be pushed inward to overcome the elastic force of the first elastic element and realize that the two clamping plates 311 in the clamping component 31 move away from each other, thereby releasing the power cord, making disconnection convenient and quick.

[0038] In the example, the first elastic element is a spring.

[0039] Furthermore, referring to Figure 2 A retractable guide rod (not shown in the figure) connects the linkage plate 34 to the inner wall of the distribution box 1. When the linkage plate 34 moves, the guide rod can move synchronously. The first elastic element is sleeved on the outside of the guide rod and abuts against the inner wall of the distribution box 1. By setting the guide rod, the first elastic element can be limited to ensure that the first elastic element always applies external force to the linkage plate 34 in the first direction.

[0040] Of course, in other alternative embodiments, the drive unit 32 may also be a drive structure such as a motor or an electric cylinder.

[0041] Optionally, a handle is provided on the side of the linkage plate 34 away from the first elastic member to facilitate driving the linkage plate 34 to move against the elastic force of the first elastic member.

[0042] Preferably, such as Figure 3 As shown, each pair of clamping plates 311 of each clamping member 31 has a concave arc-shaped surface 3112 on the opposite side to form an arc-shaped limiting space that matches the shape of the power cord, thereby improving the wire-binding effect of the clamping member 31 and making it difficult for the power cord to come out of the limiting space.

[0043] Since the limiting space of each set of clamping members 31 is the same after adjustment by the driving member 32 and the linkage member, while the outer diameter of the power cord may be different, it is difficult for the limiting space of each set of clamping members 31 to simultaneously clamp power cords of different outer diameters for cable bundling. Therefore, in some preferred embodiments, an elastic pad 9 is provided on the arc-shaped surface 3112. By providing the elastic pad 9, the size of the limiting space can be compensated for by the flexible contact between the elastic pad 9 and the power cord. For example, when one set of clamping members 31 clamps the power cord with the largest outer diameter, other clamping members 31 will compress the elastic pad 9 and undergo elastic deformation when clamping the power cord with a smaller outer diameter, so that the limiting space can match the power cord; at the same time, the flexible contact with the power cord can also prevent damage to the outer surface of the power cord.

[0044] Specifically, refer to Figure 1 and Figure 2 The distribution box 1 has wiring holes on its walls, allowing power cords to pass through these holes from the outside of the distribution box 1 and connect to the terminal blocks 2 inside. In this embodiment, the terminal blocks 2 include a first terminal module 21 and a second terminal module 22. For example, the first terminal module 21 is a 330V terminal, and the second terminal module 22 is a 220V socket, providing power at different voltages to meet the needs of different electrical devices. The first terminal module 21 and the second terminal module 22 are respectively connected to the power supply via a circuit breaker 7, which provides circuit breaker protection for the terminal blocks 2.

[0045] Rubber pads are filled between the wire hole and the power cord to improve the sealing of the distribution box 1.

[0046] Optionally, each terminal 2 is equipped with an independent control switch, with the circuit breaker 7 serving as the main circuit switch. The circuit breaker 7 is connected to the switches of each terminal 2 via copper busbars. Due to the good conductivity and large contact area of ​​the copper busbars, the resistance of the solder joints is effectively reduced, ensuring the quality of current transmission. Furthermore, the strong connection at both ends of the copper busbars prevents loosening due to vibration or temperature changes, effectively avoiding current tripping or short circuits. Moreover, copper busbar connections allow for better management of the wiring harness, reducing clutter and confusion, preventing wiring errors, and providing better management and isolation control.

[0047] Preferred, such as Figure 1 As shown, to prevent electric shock accidents caused by arcing from the circuit breaker 7 during live testing, disconnection, or wiring operations on the distribution box 1, the circuit breaker 7 is equipped with an insulating protective cover 8. By installing the protective cover 8, the arcing generated by the circuit breaker 7 can be insulated and isolated, thereby improving operational safety; it also isolates and protects the circuit breaker 7 from damage caused by rainwater or humid air contact.

[0048] Optionally, the protective cover 8 can be flipped up via a hinge structure to facilitate opening and closing of the protective cover 8 for maintenance.

[0049] Preferably, the wiring hole includes a first wiring hole and a second wiring hole. The power cord can pass through the first wiring hole to connect to the first terminal module 21 or through the second wiring hole to connect to the second terminal module 22. That is, the power cord connected to the first terminal module 21 passes through the first wiring hole, and the power cord connected to the second terminal module 22 passes through the second wiring hole, so as to separate the wiring of the first terminal module 21 and the wiring of the second terminal module 22. This avoids the situation where the wiring of the first terminal module 21 and the second terminal module 22 come into contact or are close to each other, and the short circuit, overload or arc of one of them causes the wiring of the other to be damaged in a coordinated manner.

[0050] Furthermore, such as Figure 1 As shown, an insulating partition 10 is provided inside the housing 11. The partition 10 separates the first terminal module 21 and the second terminal module 22 to ensure that the wiring of the first terminal module 21 and the second terminal module 22 is completely separated.

[0051] like Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the distribution box 1 is also equipped with a lighting component 5. The lighting component 5 includes a lighting lamp 51 and two conductive plates 52. One conductive plate 52 is connected to the power supply, and the other conductive plate 52 is connected to the lighting lamp 51. The distribution box 1 includes a box body 11 with an opening and a box cover 12 that covers the opening of the box body 11. The lighting lamp 51 is disposed inside the box body 11. A mounting groove 111 is provided at the periphery of the opening of the box body 11. Both conductive plates 52 are installed in the mounting groove 111. A second elastic member 6 is also provided in the mounting groove 111. The second elastic member 6 can drive the two conductive plates 52 to move closer together to keep them in contact, thereby electrically conducting the lighting lamp 51 and making the lighting lamp 51 emit light. A driving part 121 is provided on the box cover 12. When the box cover 12 is closed to the box body 11, the driving part 121 is inserted into the mounting groove 111 and drives the two conductive plates 52 to separate. For example, one conductive sheet 52 is fixedly disposed in the mounting groove 111 near the groove opening, and the other conductive sheet 52 is slidably disposed in the mounting groove 111 near the groove bottom. The second elastic member 6 is a spring, which is disposed between the conductive sheet 52 and the groove bottom of the mounting groove 111 to drive the conductive sheet 52 near the groove bottom to move toward the groove opening of the mounting groove 111 to fit against the other conductive sheet 52. The conductive sheet 52 near the groove opening is provided with a through hole. When the cover 12 is closed, the driving part 121 can pass through the through hole and push against the conductive sheet 52 near the groove bottom to move away from the other conductive sheet 52, so as to realize automatic light-off when the cover is closed. When the cover 12 is opened, the conductive sheet 52 automatically fits against the other conductive sheet 52 under the action of the second elastic member 6, so as to realize automatic light-on when the cover is opened, which is convenient to use.

[0052] Optionally, a first mating portion is provided within the wall of the mounting groove 111, and a second mating portion is provided on the conductive sheet 52 near the bottom of the groove to mate with the first mating portion, thereby guiding the movement of the conductive sheet 52. For example, the first mating portion is a limiting groove recessed into the wall of the mounting groove 111, the length of which extends along a first direction; the second mating portion is a protrusion protruding from the outer wall of the conductive sheet 52, the protrusion sliding within the limiting groove to restrict the direction of movement of the conductive sheet 52.

[0053] Preferably, a sensor (e.g., a photoresistor sensor) for detecting the brightness inside the enclosure 11 is installed inside the enclosure 11. The sensor and the lighting lamp 51 are respectively connected to the controller. The controller automatically detects the environment of the distribution box 1 through the sensor to automatically adjust the brightness of the lighting lamp 51. Under sufficient light conditions, the lighting lamp 51 can also be controlled to be turned off to save energy.

[0054] Since distribution box 1 is used on a ship, and the surrounding environment is relatively humid with high humidity, the humid air can easily cause short circuits and other malfunctions in the electrical components inside distribution box 1. Therefore, parameters... Figure 5In an optional embodiment, a heat dissipation assembly 4 is provided inside the power distribution box 1. The heat dissipation assembly 4 includes a dehumidifier 41, a liquid cooling plate 42, and a condenser 43. The dehumidifier 41 includes a housing 412 and an adsorbent 411 disposed inside the housing 412. The adsorbent 411 is used to absorb water vapor in the air inside the power distribution box 1 and convert it into liquid water, which is collected inside the housing 412 to dehumidify the inside of the power distribution box 1 and keep the air dry.

[0055] The electrical components are mounted on a liquid-cooled plate 42, which is equipped with cooling pipes. The inlet of the cooling pipes is connected to the outlet of the outer casing 412, and the outlet of the cooling pipes is connected to the condenser 43 and the inlet of the outer casing 412 in sequence. A water pump is installed on the cooling pipes, allowing liquid water to circulate between the outer casing 412 and the cooling pipes. This design enables the dehumidified and collected liquid water to exchange heat with the electrical components through the cooling pipes. After heat exchange, the liquid water is condensed by the condenser 43 and then re-enters the outer casing 412 for circulation, thereby continuously dissipating heat and cooling the electrical components.

[0056] Optionally, adsorbent 411 may be made from at least one of calcium chloride, montmorillonite, and activated carbon. Both calcium chloride and activated carbon have strong hydrophilicity, enabling them to adsorb surrounding water molecules onto their surfaces and form hydrates. This maintains a stable moisture absorption effect in environments with high relative humidity, effectively reducing humidity in the air and preventing moisture buildup.

[0057] The dehumidifier 41 requires a certain amount of time to collect enough water to heat the electrical components. Furthermore, the heat dissipation assembly 4 also includes a fan 44. The distribution box 1 has an air inlet and an air outlet on its wall, and the fan 44 is installed at either the air inlet or outlet, allowing outside air to circulate between the outside and inside of the distribution box 1. When the dehumidifier 41 collects insufficient water, the fan 44 can be used to dissipate heat from the electrical components, ensuring effective heat dissipation. Simultaneously, airflow accelerates water collection by the dehumidifier 41. Once the collected water reaches the required level for heat dissipation of the electrical components, water-cooled heat exchange can be used alone to reduce the amount of humid air entering the distribution box 1.

[0058] Furthermore, the liquid cooling plate 42 divides the distribution box 1 into a first chamber 13 and a second chamber 14. Electrical components are located in the first chamber 13, and heat dissipation components 4 are located in the second chamber 14. That is, the air inlet and air outlet that communicate with the outside are located on the cavity wall of the second chamber 14, making the first chamber 13 relatively closed, so as to minimize the amount of humid air entering the first chamber 13 and coming into contact with the electrical components.

[0059] Optionally, a heat-conducting element (not shown in the figure) is provided on the side of the liquid cooling plate 42 located in the first chamber 13. The heat-conducting element can be thermally conductive silicone, thermally conductive cotton, etc. The electrical components and the partition 10 are disposed on the side of the heat-conducting element facing away from the liquid cooling plate 42. By providing the heat-conducting element, the heat of the electrical components can be quickly transferred to the liquid cooling plate 42 for heat exchange, thereby further improving the heat dissipation effect of the electrical components.

[0060] Reference Figure 1 In one optional embodiment, the bottom of the distribution box 1 is provided with casters to facilitate moving the distribution box 1.

[0061] In one alternative embodiment, the outer wall of the distribution box 1 is provided with a hanging post (hanging lug) to facilitate the hanging of spare wires.
