Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering, and in particular relates to an underwater beacon bracket. Background Art

[0002] During underwater construction, ROV will fix a beacon on the ROV frame and send signals underwater through the beacon. After the signal is processed by the surface positioning system, the real-time underwater operation position of the ROV can be displayed in the construction positioning map, providing an important navigation basis for the ROV to work underwater. However, in the actual construction process, due to the influence of factors such as the underwater external environment and underwater structures, the beacon often loses or inaccurate signals during underwater work, which poses a great safety risk to the ROV in underwater construction. Signal loss and unstable signals are usually caused by the underwater beacon signal being blocked by structures or the ROV's own frame.

[0003] The traditional beacon fixing method is to directly fix the beacon on the front frame of the ROV, so as to keep the beacon signal transmission position free of obstructions to the maximum extent. However, in the specific construction process, the ROV will often work near underwater structures, and the heading, position, and depth of the ROV will change in real time when working underwater, so it is impossible to ensure that the ROV beacon is in a good position and angle for signal reception and transmission during the entire underwater operation.

[0004] Therefore, it is urgent to design an underwater beacon bracket to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide an underwater beacon bracket, which has the advantage of improving the signal stability of the beacon and solves the problems mentioned in the background technology.

[0008] Furthermore, the hydraulic telescopic assembly also includes a support base, which is fixedly connected to the ROV frame and connected to the output end of the hydraulic cylinder.

[0009] Furthermore, it also includes an ROV pressure supply unit, which is connected to the hydraulic cylinder to provide hydraulic pressure to the hydraulic cylinder.

[0011] Furthermore, a telescopic control valve is provided on the hydraulic pipeline to control the output end of the hydraulic cylinder to slide upward or downward or remain stationary.

[0012] Furthermore, the telescopic control valve is provided with a first position, a second position and a third position. When the first position is located at the working position, the discharge port of the ROV pressure supply unit is connected to the first port on the hydraulic cylinder through a hydraulic pipeline, and the liquid inlet of the ROV pressure supply unit is connected to the second port on the hydraulic cylinder through a hydraulic pipeline, so that the output end of the hydraulic cylinder moves upward. When the second position is located at the working position, the discharge port of the ROV pressure supply unit is connected to the liquid inlet of the ROV pressure supply unit through a hydraulic pipeline, and the first port and the second port on the hydraulic cylinder are closed, so that the output end of the hydraulic cylinder remains stationary.
