Description
Technical Field
The invention belongs to the technical field of submarine vacuum pipeline transportation and underwater sonar, and particularly relates to a submarine vacuum pipeline sonar system and a working method.
Background
The development and application of electromagnetic waves are one of the most important technological achievements in the recent history of human beings, and greatly influence aspects of human society economy, life and science and technology, and even military operations. Typical application fields of electromagnetic waves, such as radio telegraph, radio, radar, etc., are developed in the upper half of the 20 th century; in the latter half of the 20 th century, television, wireless communication (such as mobile phones) and satellite communication based on electromagnetic wave technology are popularized and applied on a large scale.
The most basic functions and technical features of satellite communication and terrestrial communication base stations are to transmit and receive radio waves (electromagnetic waves).
However, one of the disadvantages of the electromagnetic wave service for human beings is that it decays rapidly in water, and the propagation distance is only several tens of meters, so that the electromagnetic wave cannot be used for underwater communication. Thus, human beings cannot realize full coverage, no dead angle and full time domain for sea accounting for more than 70% of the earth surface, especially for detection and communication of the seabed world.
Unlike electromagnetic waves, sound waves attenuate very little in water, and thus sonar (Sonar) has emerged as an underwater communication technology. Nowadays, sonar has been widely used in the fields of submarines, torpedoes, underwater submarines, underwater positioning and tracking, submarine measurement, ocean exploration, etc., and these applications are characterized in that: single point and temporary.
The single-point performance means that the existing sonar equipment is scattered under the sea surface, and the effective coverage meeting the delay requirement is very limited, such as submarine sonar, torpedo sonar, marine survey sonar and the like. Although the ground communication base stations are also single point spread, the communication base stations can perform the task of transmitting/receiving radio waves with a wide range of user equipment (e.g., cell phones) in an atmosphere (or vacuum) medium relatively independently. The underwater sonar can directly transmit sound waves to each other for communication, and can also directly communicate with nearby sea ships, but cannot directly communicate with sea ships with far distance, and cannot directly communicate with remote land equipment (only through one medium).
In addition, navigation of torpedoes and underwater submarines is dependent on sonar equipped on underwater submarines or nearby sea ships, and the communication distance is very limited.
Temporary means that existing sonar equipment is used in a mobile mode or temporarily exists at a certain position, such as a submarine, a torpedo, an underwater submarine, a sea detection device and the like.
If a certain submarine facility with practical application value is used for mutual promotion and gradual development, the defect of electromagnetic wave communication is overcome, and a global submarine sonar communication network is built, the submarine sonar communication network becomes a technical development path worthy of exploration.
Subsea vacuum piping is an upcoming way of transoceanic transportation. The basic form is that a pipe pier is built on the seabed, then a vacuum pipeline section is erected on the pipe pier according to required precision by an underwater construction method, and all pipelines are fixedly connected by an underwater sealing connection method. The submarine environment has special superiority on the vacuum pipeline, seawater can cool the vacuum pipeline and provide a constant temperature environment, and can also provide uniform buoyancy for the pipeline, offset the gravity effect of the pipeline, reduce the structural strength requirement and reduce the engineering cost. In the future, the submarine vacuum pipeline is spread on all ocean floors of the world, and a submarine sonar communication network is constructed by means of the submarine vacuum pipeline, so that the submarine vacuum pipeline is expected to have good economic effects and development prospects.

Further, the sonars are respectively arranged at uniform intervals along the outer circumference of the submarine vacuum pipeline.
Further, the sonar arranged at the top of the submarine vacuum pipeline is hung above the submarine vacuum pipeline through a haulage rope, and the haulage rope is connected with a floating ball for pulling the sonar.
Further, the sonars positioned on two sides of the submarine vacuum pipeline are all arranged on a pipe pier bearing platform for supporting the submarine vacuum pipeline.
The working method of the submarine vacuum pipeline sonar system comprises the steps of running the sonar system, starting the sonar system to work, continuously detecting the sea within the distance range of a signal received by the submarine vacuum pipeline along the line, obtaining all characteristic information, positions and moving speeds of a submarine object, and transmitting the submarine object to a land control center through a signal transmission line in the submarine vacuum pipeline;
When the hidden object with unknown identity is close to the submarine vacuum pipeline, the sonar system gives out warning or interferes with sound waves to drive away; if the warning and the interference are not considered to break through the safety boundary, a destructive sound wave is sent out through the sonar system, and the sonar navigation system of the invading submarine is destroyed; or the instruction is sent to the prepared guard torpedoes or guard submarines, and the unknown submarines which invade the limit are intercepted or destroyed before the aircraft goes on;

The sonar 3 is installed at equal intervals along the outer circumference of the submarine vacuum pipeline 2 respectively, the sonar 3 installed at the top of the submarine vacuum pipeline 2 is suspended above the submarine vacuum pipeline 2 through a traction rope 61, and the traction rope 61 is connected with a floating ball 6 for traction of the sonar 3. Referring to fig. 4, the upward arrow direction in the figure is sea surface, the downward arrow direction is seabed, and the sonar 3 along two sides of the submarine vacuum pipeline 2 are all installed on a pile cap 1 for supporting the submarine vacuum pipeline 2.
