Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] Such as figure 1 As shown, the present invention includes at least two water level measuring devices 1, a comparator 2, a monitoring and display device 3 and an alarm device 4. The water level measuring devices 1 are symmetrically installed on both sides of the hull, and the output terminals of the water level measuring device 1 are arranged in the control room. Comparator 2, monitor display device 3 and alarm device 4 are connected.

[0015] The using method of the present invention comprises the following steps:

[0016] 1) In the comparator 2, the early warning value of the hull draft and the early warning value of the hull heel angle are respectively set.

[0017] 2a) When the berthed ship is heeling, the comparator 2 compares the difference between the immersion depth data measured by the two water level measuring devices 1 on both sides of the hull with t...

Abstract

The invention discloses a ship posture warning device and a ship posture warning method. The ship posture warning device comprises water level survey meters, a comparator, a monitoring display device and a warning device, wherein the water level survey meters are symmetrically mounted at the two sides of the ship body, and the output ends of the water level survey meters are connected with the comparator, the monitoring display device and the warning device which are arranged in a control chamber. The ship posture warning method comprises the following steps of 1) setting prewarning values, respectively, 2a) comparing the difference value of immersed depth data at the two sides of the ship body with the prewarning value of a heeling angle by the comparator, and warning by the warning device when the difference value reaches or exceeds the prewarning value of the heeling angle, and 2b) displaying a real-time monitoring state and giving an audible and visual alarm by the monitoring display device. The ship posture warning device and the ship posture warning method are capable of prewarning the heeling angle of the ship and protecting the ship from the danger of overturning due to overranging heeling.

Description

technical field [0001] The invention relates to a marine alarm device, in particular to a marine alarm device used to prevent the sudden danger of heel exceeding the limit when a ship is berthed, and also relates to a method for using the marine alarm device, which belongs to the technical field of ship engineering. Background technique [0002] When the ship is moored at the dock anchorage, the side of the ship is connected to the cable pile of the dock through a cable. At this time, only the on-duty personnel are usually on duty. When the tide changes, the cable breaks and the dock is prone to break due to the change of the ship’s attitude beyond the limit. damage, and even the risk of the ship sinking if it tilts into the water. Existing ships are usually equipped with depth alarms. However, the existing water depth alarms can only be used to warn the draft of ships exceeding the limit, and have no early warning effect on the overrun of the hull tilt. In fact, the overr...
