Description

Technical Field

[0001] The invention relates to the technical field of ocean internal wave monitoring, in particular to an ocean ranch internal wave frequency receiver with a waterproof structure. Background Art

[0002] Ocean internal waves are an important type of seawater movement. They are an important link in transferring large-scale and medium-scale motion energy, and are also an important reason for causing seawater mixing and forming fine structures. They will have a great impact on marine ranching, so internal wave frequency receivers are needed to monitor ocean internal waves.

[0003] In the prior art, there is a floating ocean internal wave monitor based on a vector sensor, such as the announcement number CN109798878B, which includes: an Iridium communication module, a data processing and storage module, a vector sensor, a power module and a buoyancy control chamber. The instrument adjusts the size of the buoyancy bladder in the buoyancy control chamber to float to the water body at the depth to be measured, and performs four-channel multi-component data acquisition following the movement of the internal waves. After reaching the set time period, the buoyancy control chamber adjusts the size of the buoyancy bladder to float to the surface of the sea, transmits the collected data and instrument coordinates through the Iridium communication module, and then sinks into the water body to monitor the next time period until it is recovered. The deployment and recovery of the present invention is simple, and the monitoring results are reliable; Another example is an ocean internal wave acoustic detection method with a publication number of CN102393196A, which uses acoustic methods to extract ocean internal wave parameters, that is, to simultaneously obtain the amplitude, period, propagation direction and propagation speed of internal waves in the ocean. Phased array sonar is used to measure the seawater reflection signal intensity and flow velocity of each receiving beam in the ocean layered profile, and the seawater reflection signal intensity and flow velocity of each receiving beam at different depths are analyzed to determine whether internal waves exist. Once internal waves exist, the internal wave information extraction process is started to calculate the amplitude, period, propagation direction and propagation speed of the internal waves. Internal waves induce strong movement of seawater, which is a major safety hazard for maritime military activities and marine engineering facilities, and has an important impact on the marine environment. Ocean internal wave acoustic detection technology is of great significance to the development of marine resources, the maintenance of national marine security and the promotion of marine scientific and technological progress.

[0004] However, the existing internal wave frequency receiver has a fixed sealing structure, and most of them use a single sealing rubber ring to achieve sealing, which makes it easy for seawater to penetrate when frequently immersed in seawater and cause electronic equipment failure. It is also inconvenient to clean the outside of the device shell, making it easy for marine organisms to adhere to the outside of the device and affect the frequency reception effect. There are certain usage defects. Summary of the invention

[0005] The purpose of the present invention is to provide an ocean ranch internal wave frequency receiver with a waterproof structure to solve the problem raised in the above background technology that the internal wave frequency receivers on the market currently have a fixed sealing structure and mostly use a single sealing rubber ring to achieve sealing, which makes it easy for seawater to penetrate when frequently immersed in seawater and cause electronic equipment failures, and it is inconvenient to clean the outside of the device shell, which makes it easy for marine organisms to adhere to the outside of the device and affect the frequency reception effect.

[0006] To achieve the above object, the present invention provides the following technical solution: an ocean ranch internal wave frequency receiver with a waterproof structure, comprising an inner shell for installing a frequency receiving module and a power supply, an outer shell is fixedly installed on the outer side of the inner shell, and the upper end of the inner shell passes through the top of the outer shell, and a sealing cover is fixedly connected to the top opening of the inner shell; It also includes: a floating and sinking adjustment component, which is installed in the cavity between the inner shell and the outer shell, and is used to adjust the floating and sinking position of the device; A floating adjustment member is sleeved on the outer side of the upper end of the inner shell, and a linkage connection plate is fixedly connected to the lower end of the floating adjustment member; An air storage bag is embedded and installed on the upper outer side of the inner shell, and a sealing air bag is also embedded and installed on the inner side of the inner shell; The rotating ring is rotatably mounted on the outer side of the upper part of the shell, and a cleaning member is elastically rotatably mounted on the lower end of the rotating ring.

[0011] Preferably, a first spring is connected between the floating adjustment member and the top of the outer shell, and the floating adjustment member is slidably connected to the upper portion of the inner shell.

[0012] By adopting the above technical solution, when the equipment sinks into the sea, the floating adjustment member will contact the sea water, so that the floating adjustment member will elastically move upward along the upper part of the inner shell under the action of buoyancy.

[0013] Preferably, the upper part of the floating adjustment member is provided with an inclined surface on one side close to the inner shell, and the upper part of the inner shell is elastically connected to a positioning pin through a second spring, and the floating adjustment member floats up to push the positioning pin through the inclined surface, and a positioning hole is provided on the outer wall of the sealing cover, and the positioning pin and the positioning hole constitute a plug-in locking structure.
