Problems solved by technology

[0002] At present, the cable laying equipment used in underwater construction mainly uses the cable tensioner of the surface vessel to set the pre-tension of the cable, or manually observes the angle of entry of the cable to control the tension of the cable. However, due to the length of the cable under water Change at any time and the influence of ocean currents, the setting value of the tension force can only be judged by experience, and it is easy to affect the quality of cable laying
Moreover, the distance between the tension control part and the cable embedding point is far away, so there are problems of low tension control precision and slow response speed.

Embodiment 1

[0018] Embodiment 1: as figure 1 , figure 2 As shown, the present invention includes a guide frame 1 and four force feedback mechanisms 2 connected with the guide frame 1. The guide frame 1 is provided with through holes 15 for passing cables 13 in the axial direction, and is symmetrical in pairs in the radial direction. There are four radial slots 18 communicating with the axial through holes in a cross shape. The four force feedback mechanisms 2 are installed in the radial slots 18 and extend into the axial through holes 15. When in use, the cables 13 pass through Through the axial through hole 15 of the guide frame 1, the signal output terminals of the four force feedback mechanisms 2 communicate with the external control system respectively.

[0019] Such as figure 2 As shown, the force feedback mechanism 2 includes a roller 4, a tension pressure sensor 7, a guiding and fixed base plate 12, a sealed cabin body 9, a roller bracket 16 and a connecting stud 6, and the ten...

Embodiment 2

[0026] Embodiment 2: The structure of this embodiment is the same as that of Embodiment 1, except that the angle α between the roller 4 of the force feedback mechanism 2 and the cable 13 and the tangent line of the arc surface of the guide frame 1 is 20°.

Embodiment 3

[0027] Embodiment 3: The structure of this embodiment is the same as that of Embodiment 1, except that the angle α between the roller 4 and the cable 13 of the force feedback mechanism 2 and the arc tangent of the guide frame 1 is 22°.

Abstract

The invention relates to a force feedback type underwater cable guider, which is used for a cable burying device of underwater construction. The underwater cable guider comprises a guiding frame and at least four force feedback mechanisms connected with the guiding frame, wherein through holes used for passing through a cable are arranged on the guiding frame along an axial direction; radial slot holes communicated with the axial through holes are uniformly arranged on the guide frame along a radial direction; and each force feedback mechanism is arranged in each radial slot hole and extends into each axial through hole. When the force feedback type underwater cable guider is used, the cable passes through the axial through holes of the guiding frame, and a signal output end of each force feedback mechanism is communicated with an external control system. The installation position of the cable guider is closer to a cable burying point, the underwater cable guider monitors and feeds back the stress state of each direction of the cable near the burying point, judges the current state of the cable intuitively and quickly through the change of the stress direction and size and correspondingly regulates the tensioning force and the release rate of a cable tensioner according to the state, therefore, the occurrence of unfavourable conditions, such as cable aground, too large tensioning force, and the like is effectively avoided. The underwater cable guider has the advantages of simple structure and reliable performance and is convenient for maintenance.

Description

technical field [0001] The invention relates to a force feedback type underwater cable guide, which is used in cable embedding equipment for underwater construction. technical background [0002] At present, the cable laying equipment used in underwater construction mainly uses the cable tensioner of the surface vessel to set the pre-tension of the cable, or manually observes the angle of entry of the cable to control the tension of the cable. However, due to the length of the cable under water Due to changes at any time and the influence of ocean currents, the setting value of the tension force can only be judged by experience, and it is easy to affect the quality of cable laying. Moreover, the distance between the tension control part and the cable embedding point is relatively long, so there are problems of low tension control precision and slow response speed. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention pr...
