Embodiment 1

[0040] Such as figure 1 and figure 2 as shown, figure 1The upward direction of the middle arrow is the sea surface, and the downward direction of the arrow is the seabed. The present invention provides a submarine vacuum pipeline with preset sonar sensors, which includes at least two sets of pipe sections 2 fixedly installed on the top of the pipe pier 1, and each set of pipe sections 2 is two Both ends are prefabricated with flanges 3 for connection, and multiple sets of sonar sensors 4 are pre-installed on the pipe section 2, and each set of sonar sensors 4 includes integrated active sonar sensors and passive sonar sensors arranged at even intervals, and each set of integrated active sonar sensors and Passive sonar sensors all include a transducer 41 for receiving and emitting sound waves, and converting the received sound waves into electrical signals, or converting electrical signals into sound waves for emission, and is installed on the inner wall of the pipe section 2 ...

Embodiment 2

[0051] Such as Figure 5 As shown, the upward direction of the arrow in the figure is the sea surface, and the downward direction of the arrow is the seabed. The present invention provides a submarine vacuum pipeline with preset sonar sensors. The difference from Embodiment 1 is that multiple sonar sensors 4 are uniform The intervals are pre-installed on the upper part of the pipe section 2, and the plurality of sonar sensors 4 are spherical.

[0052] The installation method of the submarine vacuum pipeline of the preset sonar sensor specifically includes the following steps;

[0053] Step 1: When the pipe section 2 is manufactured in the factory, first install each set of preset cylindrical sonar sensors 4 on the upper part of the pipe section 2, and lead the wiring into the pipe section 2 through the vacuum terminal 7, and then connect each set of sonar sensors 4 to the upper part of the pipe section 2. The integrated circuits 43 are installed on the inner wall of the pipe ...

Embodiment 3

[0057] Such as Figure 6 As shown, the upward direction of the arrow in the figure is the sea surface, and the downward direction of the arrow is the seabed. The present invention provides a submarine vacuum pipeline with preset sonar sensors. The difference from Embodiment 1 or Embodiment 2 is that each The sonar sensors 4 are correspondingly installed in a sonar base on the prefabricated pipe section 2 .

[0058] The installation method of the submarine vacuum pipeline of the preset sonar sensor specifically includes the following steps;

[0059] Step 1: When manufacturing the pipe sections 2 in the factory, first prefabricate the sonar base on each group of pipe sections 2, and pre-embed the vacuum terminal 7, and fix the integrated circuit 43 on the inner wall of each group of pipe sections 2, for each group of pipe sections The exposed integrated circuit 43 and its vacuum terminal 7 are used for temporary waterproof protection.

[0060] Step 2: Before launching each gro...

Abstract

The invention discloses a seabed vacuum pipeline with preset sonar sensors, and an installation method thereof. The seabed vacuum pipeline comprises at least two sets of pipe sections fixedly installed at the top of a pipe pier, flanges used for connection are prefabricated at the two ends of each set of pipe section, the multiple sets of sonar sensors are installed on the pipe sections in advance, and each set of sonar sensors comprises an energy converter used for receiving and transmitting sound waves and converting the received sound waves into electric signals, or converting the electric signals into sound waves and emitting the sound waves, and an integrated circuit installed on the inner wall of the pipeline and used for processing the electric signals from the energy converter, sending the processed electric signals to a central processing unit, receiving and modulating the electric signals from the central processing unit and sending the electric signals to the energy converter; each energy converter is connected with the corresponding integrated circuit through an embedded circuit; and a power supply cable for supplying power to the energy converter and a signal transmission line for transmitting signals of the energy converter are arranged in each set of pipe sections, and the power supply cable and the signal transmission line are respectively connected with the integrated circuit. The method has the advantages of optimizing the mounting process, reducing the cost and improving the benefit.

Description

technical field [0001] The invention belongs to the technical field of submarine vacuum pipeline transportation and underwater sonar, and in particular relates to a submarine vacuum pipeline with preset sonar sensors and an installation method. Background technique [0002] Electromagnetic waves attenuate quickly in water, and the propagation distance is only tens of meters, so that electromagnetic waves cannot be used for underwater communication. The attenuation of sound waves in water is very small, so sonar (Sonar) as an underwater communication technology came into being. At present, sonar has been widely used in submarines, torpedoes, underwater vehicles, underwater positioning and tracking, seabed measurement, ocean detection and other fields. [0003] Submarine vacuum pipelines are a soon-to-be implemented means of transportation across oceans and oceans. The basic form is to build a pipe pier on the seabed, and then use the underwater construction method to erect ...
