Problems solved by technology

When the deep-sea operation equipment is sampling with downward positive pressure, the reaction force of the sample is opposite to the given positive pressure, and the maximum value of the positive pressure is equal to the gravity value of the sampling equipment itself in the deep sea. When the sample reaction force is less than the sampling equipment itself When the gravity value of the deep sea is low, the equipment will work smoothly; when the reaction force of the sample is greater than or equal to the gravity value of the sampling equipment itself in the deep sea, it will cause the equipment to be unstable, or even be lifted or dumped

Embodiment 1

[0025] like Figure 1 to Figure 3 As shown, the hydrodynamic pressure applying device of the deep-sea operation equipment of the present invention includes a water resistance pressure applying mechanism installed on the equipment 1, and the water resistance pressure applying mechanism is provided with a water resistance for increasing the water resistance of the equipment 1 in the direction of gravity. The action surface, the water resistance action surface is distributed symmetrically with respect to the center of gravity of the equipment 1, and ensures the balance of the equipment 1 when subjected to water resistance in the vertical direction. When equipment 1 is in operation, it relies on its own gravity to provide positive pressure (i.e. operating propulsion). Resistance, the water resistance is superimposed on the positive pressure of the equipment 1, which is equivalent to increasing the positive pressure of the equipment 1, which can prevent the equipment 1 from being l...

Embodiment 2

[0032] like Figure 4 and Figure 5 As shown, this embodiment is basically the same as Embodiment 1. The difference is that the wing plate 2 of this embodiment is a folding plate, and the folding plate is composed of more than two flat plates 21 hinged in turn. Folding or unfolding the conversion driving mechanism in a horizontal shape, through the function of the conversion driving mechanism, the folding plate can be folded to reduce the area of ​​the water resistance acting surface, or the folding plate can be unfolded into a horizontal shape to maximize the area of ​​the water resistance acting surface change. The above conversion mechanism can adopt various driving components in the prior art, for example, a horizontally installed telescopic cylinder and the like.

Embodiment 3

[0034] A hydrodynamic pressure application method for deep sea operation equipment, comprising the following steps:

[0035] (1) A water resistance pressure mechanism is installed on the equipment 1. The water resistance pressure mechanism is provided with a water resistance surface for increasing the water resistance of the equipment 1 in the vertical direction, and the area of ​​the water resistance surface is Adjustable; the water resistance pressure applying mechanism specifically adopts the water resistance pressure applying mechanism described in the above-mentioned embodiment 1;

[0036] (2) Adjust the water resistance surface of the water resistance pressure-applying mechanism to the minimum area, and use conventional methods to place the equipment 1 at the predetermined operating position in the deep sea; during this process, the water resistance of the sampling equipment in the water will not be increased, so that no It will affect the lowering speed and downward att...

Abstract

The invention discloses a water power pressuring device and a pressuring method for deep ocean working equipment. The pressuring device comprises a water resistance pressuring mechanism arranged on the equipment, wherein the water resistance pressuring mechanism is used for enlarging water resistance acting surfaces of the equipment in the gravity direction; the water resistance acting surfaces are symmetrically distributed about the equipment center of gravity line; the pressuring device is simple in structure and capable of improving the work stability of the equipment and deepening the work depth of the equipment. The pressuring method comprises the following steps: controlling the sizes of the water resistance acting surfaces according to the actual requirement, and reducing the water resistance acting surfaces in an addressing releasing process and a recovering process of the equipment to avoid increase of the water resistance of the equipment, so as not to influence the releasing speed and the descending posture of the equipment, but play the function of protecting the equipment.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a hydrodynamic pressure applying device and a pressure applying method of deep sea operation equipment. Background technique [0002] Deep-sea drilling rig equipment and deep-sea sediment sampling equipment are deep-sea operating equipment that rely on their own weight to provide positive pressure for sampling in the deep sea. When the deep-sea operation equipment is sampling with downward positive pressure, the reaction force of the sample is opposite to the given positive pressure, and the maximum value of the positive pressure is equal to the gravity value of the sampling equipment itself in the deep sea. When the sample reaction force is less than the sampling equipment itself When the gravity value of the deep sea is low, the equipment will work smoothly; when the reaction force of the sample is greater than or equal to the gravity value of the sampling equipment ...
