一种水下设备控制主板密封结构

Abstract

本实用新型涉及水下探测设备技术领域，具体为一种水下设备控制主板密封结构，包括：主控板，主控板安装在密封盒内，密封盒包括盒体，盒体前后两侧设有防水转接头，防水转接头用于主控板和外部设备的连接，盒体一侧通过注油管连接有油液密封组件。本实用新型，利用储液罐配合滑动结构，能够将外部压力传递给油液，实现压力的动态调节，调节范围相较于传统的膜结构更大；利用三通管的开口方便进行油液补充，补充时不会破坏盒体的密封；配合压力检测模块能够实时监测油液压力，方便监测密封情况。

Claims

1. An underwater equipment control main board sealing structure, characterized by, include: The main control board (3) is installed in the sealed box (1). The sealed box (1) includes a box body. Waterproof adapters (14) are provided on the front and rear sides of the box body. The waterproof adapters (14) are used to connect the main control board (3) and external equipment. An oil sealing assembly (2) is connected to one side of the box body through an oil injection pipe (16). The oil sealing assembly (2) includes a three-way pipe (21). The first opening of the three-way pipe (21) is connected to the oil injection pipe (16). The second opening is sealed by the liquid filling screw (22) for injecting heat-conducting oil. The third opening is connected to a storage tank (24). The storage tank (24) is used to store a portion of the heat-conducting oil. The rear end of the storage tank (24) is connected to the outside. A sliding structure is connected to the rear of the middle part of the storage tank (24). The sliding structure is used to transmit external pressure to the heat-conducting oil in the storage tank (24).

2. The seal structure for a control main board of an underwater apparatus according to claim 1, wherein: The box body includes a bottom box (11), and a top cover (12) is fixedly installed on the top of the bottom box (11). A first sealing gasket (13) is provided between the top cover (12) and the bottom box (11).

3. A seal for a control board of an underwater device as defined in claim 2, wherein: The bottom box (11) is provided with a motherboard bracket (15) inside, and the main control board (3) is fixedly installed above the motherboard bracket (15) to raise the main control board (3).

4. The seal structure for a control main board of an underwater apparatus according to claim 2, wherein: The oil injection pipe (16) is located at the left end of the bottom box (11), and the oil injection pipe (16) is flush with the inner front edge of the bottom box (11).

5. The seal structure for a control main board of an underwater apparatus according to claim 1, wherein: The fluid replenishment screw (22) has a hollow structure and a pressure detection module (23) is provided at the outer end. The pressure detection module (23) is used to detect the pressure of the heat transfer oil.

6. A seal for an underwater equipment control main board as claimed in claim 1, characterized in that: The sliding structure includes a piston (25), which is axially slidably mounted inside a liquid storage tank (24). A hollow sleeve (26) is threaded onto the tail end of the liquid storage tank (24), and the hollow sleeve (26) is used to limit the maximum stroke of the piston (25).

7. A seal for an underwater equipment control main board as claimed in claim 6, characterized in that: The hollow sleeve (26) has a fixed sleeve (28) at its top end. An elastic element (29) is fitted on the outside of the fixed sleeve (28). The end face of the elastic element (29) abuts against the tail end of the piston (25).
