Embodiment 1

[0032] Such as Figure 1 to Figure 3 As shown, this embodiment provides a stabilizing device for underwater hanging equipment, including two symmetrically arranged guide covers, wherein each guide cover includes: a guide cover and a guide cover arranged on the guide cover The permeable holes on the top are installed symmetrically between the two diversion covers.

[0033] Further, the outer surface of the air guide cover is streamlined.

[0034] Further, a center of gravity structure is provided on the inner surface of the diversion cover.

[0035] Further, the center of gravity structure is located at the middle and lower part of the inner surface of the diversion cover; the water permeable hole is arranged at the upper part of the diversion cover.

[0036] Further, the number of permeable holes on the upper part of each diversion cover is 6, and the size of each permeable hole is 40 mm to 50 mm in diameter, and the 6 permeable holes are evenly distributed on the upper part...

Embodiment 2

[0041] Such as Figure 4 As shown, this embodiment provides an underwater hanging device, which includes a hanging device and the stabilizing device provided in Embodiment 1 provided at the end of the hanging device.

[0042] Further, the connection with the hanging device is realized through the docking of the stabilizing device itself.

[0043] The working process of this embodiment is: use the shore crane to put the underwater lifting equipment into a certain working depth. When the incoming flow is large, the permeable hole of the stabilizing device at the end of the lifting device can destroy the flow field generated by the flow direction and reduce the flow field. The vortex-induced vibration perpendicular to the direction of water flow enables the underwater lifting device to work stably in a range with a small angle with the vertical, increasing the detection range and improving work efficiency.

[0044] Through the above structure, the above two embodiments realize t...

Abstract

The invention provides underwater hoisting equipment and a stabilizing device thereof. The stabilizing device comprises two flow guide covers which are arranged symmetrically. Each flow guide cover comprises an outer flow guide housing and water permeating holes formed in the outer flow guide housing, and the two outer flow guide housings are symmetrically installed. The underwater hoisting equipment comprises a hoisting device and the stabilizing device arranged at the tail end of the hoisting device. According to the underwater hoisting equipment and the stabilizing device thereof, the water flow resistance on the cross section is reduced due to the streamline of the outer flow guide housings of the stabilizing device; the low gravity center is achieved through gravity center structures, and thus the stability of the equipment in the underwater hoisting process is increased; due to the design of the water permeating holes in the outer flow guide housings, vortex-induced vibration caused by water flow in reduced.

Description

technical field [0001] The invention relates to the technical field of underwater hanging equipment, in particular, to an underwater hanging equipment and a stabilizing device thereof. Background technique [0002] Underwater lifting equipment is a carrier for underwater working equipment, which needs to meet the working requirements of underwater equipment, and has certain requirements for external size, shape and underwater stability. . In the existing underwater lifting equipment, the following two methods are usually used to increase its stability: 1. By changing its shape, increasing the diversion effect to reduce resistance; The diversion effect reduces resistance; the above two methods are not suitable for special cylindrical hanging equipment. First of all, cylindrical hanging equipment is not allowed to change its shape, and it is impossible to increase the diversion effect and reduce resistance by changing its shape; secondly, cylindrical hanging equipment can on...
