Description
Technical Field
The invention relates to the technical field of ships, in particular to a method for early warning and deicing of an icing condition of a ship.
Background
With the increasing trend of global warming, the arctic channel is more and more emphasized by various shipping enterprises due to its shorter route. Because the air temperature of the arctic in winter is extremely low, when the ship sails in the arctic region, a large amount of ice strips can be accumulated on the side of the ship close to the ice surface or the water surface, so that the weight of the ship can be increased, and the draught of the ship can be increased; if the weight of the ice belt accumulated on the two side sides of the ship is different, the ship can be greatly inclined, and the risk of the ship during navigation is increased.
In addition, since the polar region may have a phenomenon of extreme night, if the ship sails in the polar region at this time, the ice condition on the ship side is difficult to observe due to the obstructed view, which also increases the sailing risk of the ship.
Therefore, a method for warning the icing condition of the ship and removing ice is needed to solve the technical problems.

Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings and the embodiment. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In order to warn the ice accumulation condition of a ship when the ship sails in an arctic region, remove the ice accumulation and ensure the normal sailing of the ship, the invention provides a method for warning the ice accumulation condition of the ship and removing the ice, as shown in figure 1. The method comprises the following steps:
s1, fixedly arranging a deicing device on the ship board side of the ship; specifically, in the embodiment, the deicing device is a steam deicing device, and high-temperature steam is quickly sprayed to the ship board of the ship, so that accumulated ice is quickly melted, ice blocks fall from the ship board side of the ship, and a deicing effect is achieved. In other embodiments, a mechanical de-icing device may be used to remove the ice, without limitation.
S2, arranging a plurality of sensors on the outboard of the ship board side of the ship;
s3, collecting ice accumulation information on the outer side of the ship board side by a sensor, and transmitting the ice accumulation information to a control system;
and S4, when the ice accumulation information is higher than the deicing threshold, the control system gives an early warning and controls the deicing device to perform deicing operation.
The deicing device is arranged on the ship board side of the ship, the plurality of sensors are arranged on the outer side of the ship board side of the ship, the ice accumulation information of the ship is collected through the sensors, and when the ice accumulation information is higher than a set deicing threshold value, the control system carries out early warning and controls the deicing device to carry out deicing operation, so that the ship can normally sail in the arctic region, and the risk of the ship during sailing is reduced.
Furthermore, the deicing device comprises a steam generating device and a steam nozzle which are communicated with each other, the steam nozzle is arranged on the ship board side of the ship, and the steam generating device is connected with the control system. The control system controls the steam generating device to be opened and closed to realize whether the deicing operation is carried out or not. The steam generating device can be connected with a steam boiler on the ship, and the steam generated by the steam boiler is collected for deicing operation. In order to facilitate the deicing operation on the whole ship and accelerate the deicing speed, optionally, a plurality of deicing devices are arranged at intervals along the length direction of the ship. The specific number may be determined according to the length of the actual ship.
Further, in step S3, the sensor is an absorption friction sensor, and after the ice accumulates on the ship, the sensor slides under the action of the accumulated ice, and the sensor transmits the displacement signal of the sensor relative to the original installation position under the action of the accumulated ice as ice accumulation information to the control system. In order to facilitate real-time monitoring of the icing condition of the whole ship, a plurality of sensors are optionally arranged at intervals along the outboard side of the ship board side.
Further, in step S4, the deicing threshold is determined according to the number of sensors generating displacement signals. That is, if the displacement signals fed back by the sensors reach the set number, the ice accumulation condition of the ship is determined to be serious, and the ship needs to be deiced in time. In this embodiment, it is preferable that the ice accumulation of the ship is determined to be serious after 80% of the sensors generate the displacement signals. Of course, in other embodiments, the de-icing threshold can be set as desired. For example, in order to further reduce the ice accumulation, the ice accumulation can be determined to be serious after 60% of sensors generate displacement signals, and the deicing operation is required to be carried out immediately.
Further, in step S4, the early warning by the control system is significant in that when the control system cannot effectively control the deicing device, a crew can be reminded to manually start the deicing device, so as to ensure that the ship sails smoothly. In order to save fuel, when the weight of the accumulated ice of the ship is reduced to a load safety value, the control system controls the deicing device to stop deicing operation. Optionally, the load safety value is determined from the draft of the vessel.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
