Description

Sound-transmitting underwater acquisition node protective shell

Technical Field

The utility model belongs to the technical field of undersea equipment, especially, relate to an acoustically transparent gathers node protective housing under water.

Background

The seabed information acquisition means that various information acquisition equipment is used for acquiring related information on the seabed and acquiring basic data of physical, chemical, biological and geological parameters of the seabed through analysis. Ocean Bottom seismometers (Ocean Bottom seismometers) are seismometers designed for observing micro-vibrations caused by earthquakes and other tectonic events at the Ocean floor. The hydrophone is widely used for communication, continent detection, target positioning, tracking and the like in deep sea, is an important part of sonar, and cannot be used for underwater detection, identification and communication, marine environment monitoring and marine resource development.

The seabed acquisition node is an earthquake observation system which directly places a detector on the seabed, can be used for observation of natural earthquake (long period or wide frequency band) and detection of artificial earthquake section (short period), and is an effective means for researching deep structures of marginal sea and ocean. The existing submarine acquisition node main body part is usually composed of a three-component seismograph, a deep sea hydrophone, other sensors, a battery, an acquisition circuit board and the like, and the main body part is usually placed in a glass shell. The traditional glass shell has the defects of poor sound transmission, poor heat transmission and low strength, not only influences the acquisition effect of information acquisition equipment such as a seismometer and a hydrophone, but also cannot provide enough protection for the acquisition equipment.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The casing sound transmission nature of gathering the node for solving present seabed is not good, join in marriage hot shortcoming poor and that intensity is not high, the utility model particularly provides an gather node protective housing under water, this casing can not exert an influence to the information acquisition performance of sensor under water, and is favorable to the heat dissipation. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1 to 3, a protective shell for an acoustically transparent underwater collection node includes a shell, an electronic cabin 1, a sensor cabin 2, a sensing opening 5, a cover plate, and a filling medium. The electronic cabin is used for integrally mounting components such as a data acquisition board, a battery and the like. The sensor cabin is used for integrally mounting sensors such as a three-component sensor, a deep water hydrophone and the like.

The electronic cabin is arranged in the shell and is a sealed cabin; the sensor capsule is arranged inside the shell. The lateral wall of casing is located to the sensing trompil, and the sensing trompil intercommunication casing outside and sensor cabin are inboard. The cover plate covers the sensing opening. The filling medium is filled in the sensor cabin. In this embodiment, the housing includes an electronic housing 3 and a sensing housing 4, the electronic housing and the sensing housing are connected to form the electronic housing, the electronic cabin is disposed in the electronic housing, and the sensing housing is disposed in the sensing housing.
