Description
Technical Field
The invention relates to the technical field of marine monitoring, in particular to a marine monitoring platform laying method and device.
Background
There are various ways for ocean monitoring, one of which is to use a large monitoring platform, which is placed in a monitoring position so as to float in the ocean. There are many types of monitoring platforms that are larger in size, such as an elongated monitoring platform with an outer diameter of 1.4m, a length of 12m, and a weight of about 14.5 tons in the form of a torpedo. This type of monitoring platform requires transport with a ship having sufficient carrying capacity and placement in the ocean. At present, because of the maturity of the ship technology, the transportation of the large-scale monitoring platform is carried out by modern ships, but after the transportation to the preset lowering position of the monitoring platform, the large-scale monitoring platform needs to be separated from the ship body to be combined with water, and the implementation of the process is difficult because of the large volume and the large dead weight of the monitoring platform. The platform is lifted horizontally, then the whole extending part is put into water, although the mode seems to ensure the stable water entering of the platform, the current ship lifting tool cannot be realized, the lifting tool extends to a distance of more than 12 meters outside the ship body, and the supporting structure cannot bear the concentration of the platform. While if the platform is pushed down directly from the side of the ship, it may be possible to access the horizontal state into the water, but because of its large dead weight, the impact forces of momentary contact with the water surface may cause damage to the platform hull and thus to the internal components. If the platform is pushed out from the tail or the head of the ship body along the length direction of the platform, one end of the platform is firstly filled with water, then the other end of the platform is later inclined into water, if the operation is carried out in a pushing-down mode, the stress difference of different parts of the whole platform is overlarge in a short time in the process, and the situation that the whole platform is bent or broken is damaged is likely to occur. Moreover, the water entering mode can cause the platform to strike the ship due to instability of the platform after entering water, so that the platform and the ship are damaged. Therefore, how to ensure that the platform stably enters water, and the platform cannot be damaged or the ship is damaged in the water entering process is a technical problem to be solved.

The base 48 is secured to the deck of the hull. The pulley assembly is located at the lower middle part of the beam structure of the hanger 47, and is used for bearing the pulling force of the main suspension cable 44, and the part, which is towards the stern after the main suspension cable 44 passes around the pulley assembly, is connected with the two sub suspension cables 45. Related winding and unwinding components of the auxiliary hoist cable 46, such as a small cable winding and unwinding device, or pulley components corresponding to the auxiliary hoist cable 46, are symmetrically disposed at both sides of the upper portion of the hanger 47.
Referring to fig. 9, at least three suspension points are provided along the length of the monitoring platform 100, including,
the first suspension point 41 is arranged in the direction of the monitoring platform 100 approaching the middle part of the ship body;
a second suspension point 42 located between the first suspension point 41 and the third suspension point 43;
a third suspension point 43 disposed in a direction in which the monitoring platform 100 is far from the middle of the hull;
the first suspension point 41 and the second suspension point 42 play a main bearing role in hoisting, and the third suspension point 43 plays a main role in anti-swing left-right compensation.
Referring to fig. 4, a layout illustration of a hoist cable is shown, as the device angle in this figure may facilitate the illustration of hoist cable status, and the hoist cable illustration is omitted in other figures. The lifting appliance 4 is provided with a main lifting cable 44 and an auxiliary lifting cable 46, wherein one end of the main lifting cable 44 is fixedly connected with the first lifting point 41 and the second lifting point 42 respectively through two sub-lifting cables 45, the other end of the main lifting cable is connected with a main cable winding and unwinding assembly after bypassing the pulley assembly, and the main cable winding and unwinding assembly can be fixedly arranged on the traction assembly 2 or can be directly fixed on a ship board.

As one implementation of the secondary hoist cable 46, a cable take-up and pay-off device, such as a winch, is provided on each side of the pulley assembly. And a pulley corresponding to the auxiliary suspension cable is respectively arranged at two upper corners of the portal structure of the suspension frame 47, and the two auxiliary suspension cables 46 are fixed on the third suspension point 43 of the monitoring platform 100 by taking the middle position of the suspension frame 47 as a starting point and bypassing the pulley at the corners. The advantage of this approach is that the triangle formed by the force application route formed by the several force application points of the main suspension cable 44 and the sub suspension cable 45 and the triangle formed by the several force application points of the sub suspension cable 46 are distributed on different planes, the direction of the force application of the main suspension cable 44 and the sub suspension cable 45 is mainly located in the longitudinal section direction of the ship body, and the force application distribution position of the sub suspension cable 46 is more prone to be located in the transverse section direction. Such a force application may provide greater stability of the monitoring platform 100 in suspension. And the direction of the monitoring platform 100 can be corrected to a certain extent by respectively adjusting the lengths of the two auxiliary hoist ropes 46.
On the basis of the above embodiment, the initial state of the hanger 47 in step S2 is inclined toward the midship direction; the state of the hanger 47 and the monitor platform 100 and the platform bracket 1 at this time is shown in fig. 1.

S402, the platform bracket 1 drives the monitoring platform 100 to continuously move towards the outer side of the ship body,taking the included angle between the hanging bracket 47 and the horizontal plane in the middle of the ship body as alpha, the hanging bracket 47 rotates and rises to the angle alpha during the movement of the monitoring platform 100,referring to fig. 3, which shows the state of this step, the platform support 1 and the monitoring platform 100 are partially moved to the outside of the hull, and the platform support 1 and the monitoring platform 100 are about one half of the length to the outside of the hull. At this time, the hanger 47 starts to stand up in the vertical direction, and at this time, the hanger 47 does not apply force to the monitoring platform 100, and the stand-up posture is prepared for the subsequent links.
On the basis of the foregoing embodiment, step S5 specifically includes,
s501, referring to FIG. 4, under the condition that the monitoring platform 100 is kept fixedly connected with the platform bracket 1, the monitoring platform 100 is driven by the platform bracket 1 to turn over, the included angle of the horizontal plane of the central line of the monitoring platform 100 towards one side of the ship body is beta, the monitoring platform 100 is turned over to an angle beta,in the overturning process, the end part of the monitoring platform 100 is gradually filled with water; the hanger 47 rotates to α, < > in response to the movement of the platform bracket 1>In this state, it is necessary to ensure that both the hoist cable 44 and the sub hoist cable are in a stressed state, so as to ensure the safety of the subsequent links.
