Indicating navigation mark capable of automatically collecting, releasing and tying mooring rope along with changes of water level

Abstract

The invention provides an indicating navigation mark capable of automatically collecting, releasing and tying a mooring rope along with changes of the water level, which belongs to the technical field of channel navigation and comprises a power supply device, a rope length measuring device, a control and communication unit, a depth measuring device, a collecting and releasing winch, a navigation mark ship, an anchor rope and an anchor. The rope length measuring device consists of three holddown wheels and photoelectric encoders, and the photoelectric encoders are arranged on end surfaces of the holddown wheels; the depth measuring device comprises an ultrasonic depth finder, a foam floating ball and a depth measuring probe; and the power supply device is fixed onto a deck of a stern of the navigation mark ship, the control and communication unit is fixed to the rear of a body of the navigation mark ship, the rope length measuring device is fixed onto a deck of a bow of the navigation ship, the depth measuring device is fixed to the middle rear of the body of the navigation ship, the collecting and releasing winch is fixed onto a deck of the middle front of the navigation ship, one end of the anchor rope is wound on the collecting and releasing winch, and the other end of the anchor rope penetrates through the rope length measuring device and hinged with the anchor by a standard part. The indicating navigation mark has the advantages that the position of the indicating navigation mark and tension of tying of the mooring cable are automatically adjusted in real time, and navigation safety is guaranteed.

Description

technical field [0001] The invention relates to a waterway indicating navigation mark, in particular to an indicating navigation mark which can be automatically retracted and retracted with a cable as the water level changes, and belongs to the technical field of waterway navigation. Background technique [0002] Indicating navigation mark is an important symbol to reflect the scale of the channel, determine the direction of the channel, demarcate the boundary of the channel, reveal the information of the channel, and guide the safe navigation of the ship. According to the data, the main measure currently adopted for the installation of the navigation mark on the Yangtze River channel is to moor the navigation mark ship at the corresponding position of the channel, and the ship is equipped with different functional navigation lights to indicate the channel. However, the inconvenience brought by this method is that the position of the fixed-mooring cable-length buoy ship will...

Problems solved by technology

However, the inconvenience brought by this method is that the position of the fixed-mooring cable-length buoy ship will change with the change of the river water level. At the same time, there is a danger that the mooring cable will be broken due to the increase of tension, resulting in the loss of the indicating buoy. The management personnel manually adjust the length of the mooring cable of the buoy to adjust the position of the buoy to ensure that the buoy is in a proper position
