[0050] Example 2

[0051] Such as Figure 5 As shown, the direction of the arrow in the figure is a sea surface, the direction of the arrow is a seafood, and the present invention provides a preset sonar sensor seabed vacuum pipe, and is different from the first embodiment in that the plurality of sonar sensors are uniform. The interval is preset is mounted on the upper portion of the pipe section 2, and the plurality of sonar sensors 4 are spherical.

[0052] The preset sonar sensor is installed in the subsea vacuum pipeline, which includes the following steps;

[0053] Step 1: When the plant manufacturing pipe section 2, each of the preset each set of cylindrical echo sensors 4 is first mounted on the upper portion of the pipe section 2, and the wiring is introduced into the tube section 2 by the vacuum terminal 7, and each group of schus sensor 4 belongs. The integrated circuit 43 is mounted on the inner wall of the pipe section 2;

[0054] Step 2: After the tube segment 2 is co...

[0056] Example 3

[0057] Such as Figure 6 As shown, the arrow in the figure is in the direction of the sea, the direction of the arrow is a seabed, and the present invention provides a preset sonar sensor seabed vacuum conduit, and is different from the example 1 or Example 2, each The sonar sensor 4 corresponds to a sonar base mounted on the prefabricated pipe section 2.

[0058] The preset sonar sensor is installed in the subsea vacuum pipeline, which includes the following steps;

[0059] Step 1: When the plant manufacturing pipe section 2, the sonar base is pre-made on each set of pipe segments, and the vacuum terminal 7 is applied, and the integrated circuit 43 is fixedly mounted on the inner wall of each set of pipe segments 2, for each group of pipe segments. Internal exposed integrated circuit 43 and its vacuum terminal 7 make temporary waterproof protection.

[0060] Step 2: Before the installation pipe segment 2 is placed on the corresponding sonar base, the wire is con...

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 ...
