Description

Technical Field

[0001] The utility model belongs to the field of power supply boxes, and in particular relates to a moisture-proof power supply box for ships. Background Art

[0002] The power box consists of a box body and the components inside it. As one of the core equipment of the power system, the safe use of the power box has a direct impact on the normal operation of the power system. Therefore, to ensure the safe use of the components in the power box, the box body of the power box not only has the function of accommodating the components, but also needs to provide safety protection for the components to avoid damage to the components caused by environmental conditions such as dust, high temperature and humidity.

[0003] The operating environment of a marine power box has a higher humidity, so the moisture-proofing requirement is greater. Existing power boxes are moisture-proofed by having a built-in moisture-proof agent that can recover after heating. However, in places with high humidity such as ships, the moisture-proof agent set at fixed points can only absorb moisture and prevent moisture from passing through or surrounding the air. Specifically for the dehumidification scenario in the power box, since multiple components are regularly arranged in the power box, there are large and small gaps that are prone to moisture accumulation, and the range of natural air flow in the power box is small, so that the moisture-absorbing and moisture-proofing range that can be covered by the moisture-proof agent set at fixed points is limited. In view of the above problems, the utility model provides a marine moisture-proof power box. Utility Model Content

[0004] The purpose of the utility model is to provide a marine moisture-proof power box in order to solve the above-mentioned problem.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] The utility model provides a moisture-proof power box for a ship, comprising a box body, and also comprising a heat exchanger, a fan and a compressor arranged on the outer side of a back plate of the box body, the fan, the compressor and the heat exchanger are connected in sequence, the air outlet of the heat exchanger is connected with the inner cavity of the box body through an exhaust pipe, a water tank connected with the drain outlet of the heat exchanger is arranged on the outer side of the box body, and a plurality of ventilation and moisture-proof parts evenly distributed are embedded in the side wall of the box body.

[0007] As a further optimization scheme of the utility model, the ventilation and moisture-proof component includes an installation frame with a U-shaped structure and the openings on both sides of the installation frame are covered with partition nets. A plurality of moisture-proof blocks and partition blocks are arranged in the installation frame and the moisture-proof blocks and the partition blocks are interspersed.

[0008] As a further optimization scheme of the utility model, four tripods distributed in a rectangular array are provided under the box body. The water tank is located at the bottom of the box body and is detachably connected to the tripod through card slots corresponding to the tripods one by one. The water tank is connected to the heat exchanger through a water inlet pipe and the water inlet pipe and the drain outlet of the heat exchanger are screwed together by threads.

[0009] As a further optimization solution of the utility model, a protective net is provided on the back side of the box body, and the fan, compressor and heat exchanger are all located in the protective net.

[0010] As a further optimization solution of the utility model, a flow divider is provided on the inner side of the back plate of the box body. The flow divider is in a funnel-shaped structure and a plurality of ventilation slots distributed in a circular array are opened in the side wall.

[0011] The beneficial effects of the utility model are:

[0012] On the one hand, the marine moisture-proof power box can absorb moisture from the air entering and exiting the power box through the ventilation and moisture-proof parts, thereby achieving a static moisture-proof effect. On the other hand, by intermittently opening the air dehumidification system composed of a heat exchanger, a compressor, and a fan, the effect of intermittently injecting dry air into the power box is achieved. The dry air can fully cover the power box for dehumidification and heat dissipation, and can also assist the ventilation and moisture-proof parts to quickly dehumidify to restore their moisture absorption function, thereby comprehensively improving the moisture-proof performance of the power box and solving the problems raised by the background technology.

[0018] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-4As shown, the marine moisture-proof power box of this embodiment includes a box body 1, and also includes a heat exchanger 3, a fan 5 and a compressor 4 arranged on the outside of the back plate of the box body 1. The fan 5, the compressor 4 and the heat exchanger 3 are connected in sequence, and the air outlet of the heat exchanger 3 is connected to the inner cavity of the box body 1 through the exhaust pipe 6. The outside of the box body 1 is provided with a water tank 8 connected to the drain outlet of the heat exchanger 3, and the side wall of the box body 1 is embedded with a plurality of evenly distributed ventilation and moisture-proof parts 11.

[0021] Under normal conditions, the air flows in and out of the box 1 by passing through each ventilation and moisture-proof part 11. During this process, the ventilation and moisture-proof part 11 can absorb moisture for the air flow in and out of the box 1. At the same time, the air dehumidification system formed by the compressor 4, the fan 5 and the heat exchanger 3 will be turned on intermittently. During the on-time period, under the action of this dehumidification system, the air outside the box 1 is first dehumidified and then injected into the box 1, and then passes through each component in the box 1 and finally passes through each ventilation and moisture-proof part 11 to pass through the box 1. In this process, on the one hand, the dry air that has been dehumidified can take away the accumulated moisture and the heat generated by the operation of the components in the process of flowing through the various components in the box 1, thereby achieving the effect of dehumidification and heat dissipation. On the other hand, after absorbing heat, the dry air can pass through the ventilation and moisture-proof part 11 to heat the moisture-proof block 1102 therein, thereby accelerating the dehumidification efficiency of the moisture-proof block 1102, which is conducive to quickly restoring the moisture absorption effect of the moisture-proof block 1102, thereby maintaining a long-term and effective moisture-proof effect.

[0022] The ventilation and moisture-proof component 11 includes an installation frame 1101 of a U-shaped structure and both side openings of the installation frame 1101 are covered with partition nets 1104. A plurality of moisture-proof blocks 1102 and partition blocks 1103 are arranged in the installation frame 1101 and the moisture-proof blocks 1102 and the partition blocks 1103 are interspersed. The interspersed moisture-proof blocks 1102 are in more uniform contact with the airflow, which not only has a better moisture absorption effect, but also can discharge moisture faster to restore the moisture-proof effect.

[0023] Four tripods 10 distributed in a rectangular array are provided below the box body 1. The water tank 8 is located at the bottom of the box body 1 and is detachably connected to the tripod 10 through slots corresponding to the tripods 10. The water tank 8 is connected to the heat exchanger 3 through a water inlet pipe 9, and the water inlet pipe 9 is connected to the drain port of the heat exchanger 3 through a threaded connection, which is convenient for regularly removing the water tank 8 separately to clean up the accumulated water.

[0024] A protective net 2 is provided on the back side of the box body 1. The fan 5, the compressor 4 and the heat exchanger 3 are all located inside the protective net 2. The protective net 2 can play a dust-proof role.

[0025] A diverter hood 7 is provided on the inner side of the back plate of the box body 1. The diverter hood 7 is a funnel-shaped structure and a plurality of ventilation slots distributed in a circular array are provided in the side wall. The air output from the exhaust pipe 6 will flow to different directions in the box body 1 after passing through the diverter hood 7, so that the dry air can cover various parts in the box body 1, thereby further improving the dehumidification and heat dissipation effects.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
