Description

Technical Field

[0001] This utility model belongs to the field of new energy ships, and specifically relates to a high-voltage power distribution cabinet for new energy ships. Background Technology

[0002] During ship operation, vibrations are generated by the propulsion system, wave impact, and equipment operation. Existing high-voltage switchgear is usually bolted directly to the deck, and ship vibrations can easily cause these bolts to loosen.

[0003] On the other hand, new energy ships are in a complex environment of high humidity, salt spray and condensation for a long time. The high humidity of the marine atmosphere can easily penetrate into the high-voltage distribution cabinet of the ship and adhere to the surface of the insulation. Temperature fluctuations in the cabin can easily cause condensation to form in the cabinet, which accelerates metal corrosion and insulation aging.

[0004] At the same time, high-voltage switchgear itself has the problem of heat dissipation during operation.

[0005] When solving the above problems, multiple solutions are usually used separately. For example, loose bolts are solved by one method, dehumidification is solved by another method, and heat dissipation is solved by yet another method.

[0006] Within the limited space of a ship, is there a method that can simultaneously solve the above three problems to improve space utilization or reduce the cost of solving the problems? Utility Model Content

[0008] This utility model provides a high-voltage power distribution cabinet for new energy ships, comprising:

[0009] The cabinet has a columnar honeycomb bottom plate and an air vent on the top plate.

[0010] The base has a groove, the shape of which can perfectly accommodate the bottom of the cabinet; the bottom of the groove has several bottom holes that can communicate with all the honeycomb holes.

[0011] The irregularly shaped bolts and their corresponding nuts correspond to the shape of the honeycomb holes. After the irregularly shaped bolts pass through the honeycomb holes and the bottom holes, they are tightened with the nuts to fix the cabinet to the base.

[0012] And, a fan located below the bottom hole.

[0016] As a further optimization of this utility model, the honeycomb holes are hexagonal prisms.

[0017] As a further optimization of this utility model, the irregular bolt includes:

[0018] A screw with dimensions corresponding to the second bottom hole;

[0019] A positioning part located at one end of the screw and whose shape corresponds to the honeycomb holes;

[0020] And a cap located at the end of the positioning part that prevents irregularly shaped bolts from passing through the honeycomb holes.

[0021] As a further optimization of this utility model, the irregular bolt includes a first bolt and a second bolt;

[0033] like Figure 1-6 As shown, this embodiment includes a cabinet 1, a base 2, a fan 3, irregular bolts 4, and nuts 5.

[0034] In this embodiment, the cabinet 1 adopts a cube structure of a general shape. In other embodiments, it may also adopt a cylindrical or other prismatic shape.

[0035] Cabinet 1 includes a bottom plate 1a and a top plate 1b.

[0036] The top plate 1b is provided with several air outlets 1b1. In this embodiment, the air outlets 1b1 are composed of a rectangular array of several strip-shaped oval holes.

[0037] The base plate 1a is provided with columnar honeycomb holes 1a1. The base plate 1a has a certain thickness, which is required to provide columnar honeycomb holes 1a1. This structure provides the base plate 1a with a certain support strength and facilitates air intake.

[0038] The base 2 is made of stainless steel plate. A groove 2a is set at the installation position of the cabinet 1 on the stainless steel plate. The shape of the groove 2a corresponds to the bottom of the cabinet 1, so that the groove 2a can just accommodate the bottom of the cabinet 1.

[0039] The bottom of the groove 2a is provided with several bottom holes, so that the honeycomb holes 1a1 can all be connected to the bottom holes, so that the honeycomb holes 1a1 will not accumulate water.

[0040] After the irregular bolt 4 passes through the honeycomb hole 1a1 and the bottom hole, it is tightened with the nut 5 to fix the cabinet 1 on the deck.

[0041] Since the groove 2a restricts the movement of the cabinet 1 in the front-back and left-right directions, and the irregular bolts 4 and nuts 5 limit the movement of the cabinet 1 in the up-down direction, the cabinet 1 is completely fixed.

[0042] Compared to directly fixing the cabinet 1 to the deck with bolts, the structure in this embodiment ensures that the irregular bolts 4 will not easily loosen even if the ship is violently rocked for a long time.

[0043] Because the cabinet 1 in this embodiment is used on a ship, it is not placed at the very bottom, as there is usually space below the deck. In this embodiment, the fan 3 is located below the deck, that is, below the bottom plate 1a. The fan 3 faces the honeycomb holes 1a1 and blows air upwards. After passing through various electrical components inside the electrical cabinet, the air carries away heat and moisture and is discharged from the air outlet 1b1 on the top plate 1b of the cabinet 1.

[0044] Furthermore, in this embodiment, a gable roof 6 is provided above the top plate 1b to prevent the exhaust heat from condensing and flowing back into the cabinet 1 through the air outlet 1b1.

[0045] In another embodiment, the fan 3 is separated from the cabinet 1 to reduce the impact of the fan 3 vibration on the cabinet 1.

[0046] In another embodiment, to ensure that all honeycomb holes 1a1 are connected to the bottom hole, a through hole is provided on the bottom surface of the groove 2a corresponding to each honeycomb hole 1a1. While this structure achieves the desired function, it places high demands on processing and installation.

[0047] In this embodiment, the bottom hole includes a first bottom hole 2b and a second bottom hole 2c.

[0048] The first bottom hole 2b is provided and is rectangular, and the first bottom hole 2b occupies most of the area of ​​the bottom surface of the groove 2a.

[0049] There are four elongated second bottom holes 2c, which are located on the four sides of the first bottom hole 2b. The second bottom holes 2c are used to fix the irregular bolts 4.

[0050] The bottom hole structure in this embodiment can effectively ensure that all honeycomb holes 1a1 are connected to the bottom hole, and the processing and installation requirements are lower.

[0051] In this embodiment, the honeycomb holes 1a1 are hexagonal prisms. In other embodiments, the honeycomb holes 1a1 may be configured in other shapes.

[0052] In this embodiment, the irregular bolt 4 includes a screw 4a, a positioning part 4b, and a cap 4c.

[0053] The dimensions of the screw 4a correspond to the second bottom hole 2c, so that the screw 4a can pass through the second bottom hole 2c exactly.

[0054] A positioning part 4b is located at one end of the screw 4a. The shape of the positioning part 4b corresponds to the honeycomb hole 1a1, so that after the positioning part 4b is inserted into the honeycomb hole 1a1, the screw 4a cannot rotate around its axis. This further reduces the possibility of bolt loosening due to vibration.

[0055] The cap 4c is located at the end of the positioning part 4b. The area of ​​the cap 4c is slightly larger than the honeycomb hole 1a1 in at least one direction. That is, when the positioning part 4b is inserted into the honeycomb hole 1a1, at least part of the area of ​​the cap 4c is supported by the end face of the honeycomb hole 1a1, so that the irregular bolt 4 will not pass through the honeycomb hole 1a1.

[0056] Specifically, the irregular bolt 4 includes a first bolt and a second bolt.

[0057] The cross-section of the first bolt positioning part 4b is rectangular, and its length and width correspond to the distance and width of the two opposite faces of the honeycomb hole 1a1.

[0058] The cross-section of the second bolt positioning part 4b has two opposing sharp corners, which correspond to the two opposing sharp corners of the honeycomb hole 1a1, respectively.

[0059] The first and second bolts can be inserted into the honeycomb hole 1a1 from different angles.

[0060] Preferably, in this embodiment, a drying module is provided between the fan 3 and the honeycomb hole 1a1. The drying module can dry the air sent by the fan 3 and remove moisture.

[0061] In another embodiment, the drying module is located below the fan 3.
