Description

Technical Field

[0001] The utility model relates to the technical field of marine seismic exploration, in particular to a vertical cable for marine seismic exploration. Background Art

[0002] As we all know, marine seismic exploration uses the characteristics of seismic waves propagating in the ocean to capture seismic signals through sensors and measuring equipment placed on the seabed or on the water surface, so as to study the geological structure of the seabed and underground, search for oil and gas resources, monitor geological disasters, etc. This technology analyzes the propagation path and reflection characteristics of seismic waves to reveal important information such as underground rock formations, faults and topography, and provide key data support for geological science research and resource exploration. Usually, marine seismic exploration requires the use of vertical cables, which are mainly used to suspend seismic sensors or seismic recorders to ensure that they can be accurately deployed on the seabed or the bottom of the ocean, thereby effectively recording seismic data.

[0003] However, traditional vertical cables used in marine seismic exploration are usually soft and long, which gives them a certain degree of freedom in the water. When ocean currents or water flows through the cables, fluid dynamic effects are generated on and around the cable surface, causing the cable to be pushed or pulled. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a vertical cable for marine seismic exploration. When the vertical cable for marine seismic exploration is used, by installing an anchor ball of appropriate size as required, the threaded sleeve is conveniently connected through a threaded rod, and the anchor ball can be effectively fixed on the vertical cable to prevent the anchor ball from falling off or moving due to environmental factors. The slider is conveniently positioned through a slide groove, and the friction generated by the slider sliding in the slide groove is conveniently reduced through a roller, thereby making the sliding more convenient, and then the anchor ball slides to the bottom of the cable body. By adding a suitable number of anchor balls, the cable body can be stabilized and its movement in the water flow can be reduced, thereby reducing the position change caused by the fluid dynamics effect.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

The suitable number of buoys can be conveniently installed and placed on different mounting half rings as needed, thereby adapting to different needs and environmental conditions, reducing the swaying and swinging of the vertical cable in the water, ensuring the overall stability, and having high practical performance.

[0009] Furthermore, a seismic sensor is provided in the middle of the lower surface of the cable body;

[0010] Through the above technical solution, it is convenient to detect seabed earthquake fluctuations through seismic sensors.

[0011] Furthermore, the front end and the rear end of the slide groove are provided with limit grooves, and the outer walls of the front end and the rear end of the slide block are fixedly connected with limit blocks;

[0012] Through the above technical solution, the matching is improved by using the limiting grooves and the limiting blocks.

[0013] Furthermore, the limit blocks are slidably connected inside the limit grooves respectively;

[0014] Through the above technical solution, the limiting blocks are slidably connected inside the limiting grooves, so that the sliding block can be limited.

[0016] Through the above technical solution, the friction of the slider when sliding is reduced by the roller, making the sliding more convenient.

[0017] Furthermore, the middle part of the upper surface of the mounting half ring is connected to a mounting plate via a plurality of bolts;

[0018] Through the above technical solution, the matching is improved by installing the plate.

[0019] Furthermore, the anchor ball is made of aluminum alloy;

[0020] Through the above technical solution, the anchor ball is made of aluminum alloy, which has a lower density. This means that the anchor ball is lighter overall while maintaining sufficient weight, which helps reduce the tension on the cable and makes it easier to maintain a vertical state in the water.

[0021] Furthermore, the float is made of polyethylene;

[0022] Through the above technical solution, polyethylene has a very low density, which means that it can provide high buoyancy, which is crucial for keeping the vertical cable in a vertical state in the water.
