Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The observation data can be uploaded to the mother ship on the surface through the communication between the PIES and the remote control system, or can be obtained by reading the storage device after the PIES is recovered, to monitor the fluctuation of the main thermocline of the ocean, and to use it in combination with pressure data and historical hydrological da...

Abstract

The embodiment of the invention discloses a pressure sensor equipped inverted echo sounder comprising a hollow glass floating ball and a protection shell arranged outside the glass floating ball. The glass floating ball has two hemispherical balls; a support plate is installed in the glass floating ball; and a circuit board and batteries of a pressure sensor equipped inverted echo sounder are fixed by the support plate. A pressure sensor hole is formed in a lower hemispherical ball case of the glass floating ball and thus an external connector of the pressure sensor is arranged by a watertight port; and a pressure sensor is arranged in the glass floating ball. Besides, a vacuumizing hole is formed in a case of the glass floating ball and is used for realizing vacuumizing processing inside the glass floating ball. The material employed by the glass floating ball has the higher corrosion-resistant property than that of the metal material and the high-strength protection shell is also used for protection, so that usage security of the pressure sensor equipped inverted echo sounder for long time can be improved. Moreover, the glass floating ball is processed by vacuumizing and thus the great floating force can be provided, so that great convenience can be provided for underwater work.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to a pressure-sensing inverse echometer. Background technique [0002] Pressure sensor equipped Inverted Echo Sounders (PIES) is a data acquisition device for underwater surveying and mapping. The PIES placed under the water surface can regularly emit acoustic signals towards the water surface, receive the reflected echoes from the water surface, and detect and store the arrival time of the echoes. The observation data can be uploaded to the mother ship on the surface through the communication between the PIES and the remote control system, or can be obtained by reading the storage device after the PIES is recovered, to monitor the fluctuation of the main thermocline of the ocean, and to use it in combination with pressure data and historical hydrological data. The empirical formula indirectly calculates the changes of water parameters such as temperature, salinity and density a...
