According to the structure description, during specific operation, the self-return probe is thrown at fixed points, and falls into water freely; the self-return probe sinks under the action of gravity, and the equipment is kept in a vertical state at any time under the action of the guide wings and the guide holes; the self-return probe then penetrates into the sediment under the force of gravity to complete the detection. After the detection task is completed, the releaser is sprung off through a ship release signal (such as an acoustic signal), the self-returning unit is separated from the detection unit, and then the self-returning unit returns to the sea surface under the action of buoyancy, so that data transmission is completed.
Implementation 2, aiming at the self-return probe proposed in embodiment 1, in order to ensure that the self-return probe is ensured to be vertical in the laying process, and further ensure the validity of detection data, the weight of the self-return probe, the length of the probe and the floating center and gravity center of the probe need to be designed, and the optimal design of the structure is realized through solving and analyzing, and the method specifically comprises the following steps:
step 1, self-returning probe weight and multi-element probe length design:
in order to analyze whether the self-return probe can penetrate into the sediment by means of self-gravity, the factors such as the falling speed of the self-return probe, the resistance of the sediment and the like are required to be considered, the design of the whole weight of the self-return probe device and the length of the multi-element probe is carried out, so that the self-return probe is ensured to have enough penetrating force to penetrate into the sediment, and the probe penetrating process is analyzed as follows:
the depth to which the self-return probe can penetrate the soil when penetrating the sediment is preliminarily predicted by conservation of energy:
E k +E p ＝W
wherein E is k To equip with kinetic energy E p To equip potential energy, W is the work done by penetration resistance generated by sediment, v is the designed falling speed of the self-returning probe device in water; m is the total weight of the self-returning probe, mainly due to end resistance and sidewall friction.
According to the current design, the end resistance is 150kPa, the side friction resistance is changed according to the property of the sediment and the penetration depth of the probe, the design is 50kPA, and the resistance work of the sediment is simply expressed as
Wherein A is the area of the soil entering end, m 2 The method comprises the steps of carrying out a first treatment on the surface of the D is the diameter of the multi-element probe, m; the method comprises the steps of carrying out a first treatment on the surface of the l is the length of the multi-element probe. In the actual calculation process, potential energy of equipment is ignored, and under the condition of only considering kinetic energy, according to the design bottom falling speed and sediment side friction resistance, whether the probe can completely penetrate into the sediment can be calculated. The relationship between the probe length and the total device weight m and the designed drop velocity v is:
step 2, determining the floating center and the gravity center position of the probe:
the probe point is taken as an origin, a three-dimensional space coordinate system is constructed, the static moment of the device in three directions can be solved according to the mass and other known parameters of the device, and the center of gravity and the floating center of the device are calculated according to the static moment of the device; in the current structure, the center of gravity position and the position of the floating center of the probe are as follows:
center of gravity position:
floating center position:
wherein ΣM x ，∑M y ，∑M z Respectively, the static moment in three directions, sigma M is the total mass, and Sigma V is the total volume. In order to maintain the downward posture of the probe during the sinking process, it is necessary to have
(L is the total height of the device), but the probe is tilted by the horizontal force of the wave flow. Therefore, a certain vertical distance is arranged between the gravity center and the floating center, and the gravity is larger than the buoyancy force in the sinking process due to the fact that the gravity center is downward, so that a restoring moment for restoring the probe to the initial position exists, and the probe is ensured to keep a vertical posture. The current structural design, because the body is on the top, has improved the position of centre of buoyancy greatly, has guaranteed the vertical of probe course of working.
The novel probe structure provided by the scheme realizes the rapid and efficient measurement of parameters in the ocean, sediment and even air, and improves the ocean detection efficiency; and the structural design that the probe is separated from the control system is innovatively adopted, so that the recovery process is simplified, and the problem of difficult recovery at present is overcome. And the probe is ensured to be kept vertical in the working process, and can penetrate into sediment at a vertical angle, so that the effectiveness of detection data is ensured.
The present invention is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present invention without departing from the technical content of the present invention still belong to the protection scope of the technical solution of the present invention.

constructing a three-dimensional space coordinate system by taking the end point of the probe as an origin, solving the static moment of the self-return probe in three directions according to the weight of the self-return probe and related parameters, and determining the positions of the gravity center and the floating center according to the static moment:
center of gravity position:
floating center position:
wherein ΣM x ，∑M y ，∑M z Respectively referring to static moment in three directions, wherein Sigma M is the total mass, and Sigma V is the total volume;
and ensure that
L is the total height of the self-returning probe.
