Example 1
Referring to fig. 1 and 2, embodiments of the present application provide a method for checking the mounting angle of a side light mounted on a ship bow, for checking whether the mounting angle of the side light with respect to the right front of the ship bow is acceptable, particularly the side light mounted on the ship bow.
The method for checking the installation angle of the gangway lamp installed on the bow comprises the following steps:
step S100, a laser lamp capable of emitting colored laser is arranged on a porter, an emitting path of the colored laser falls into a range that the luminous intensity of the porter in the heading is weakened to be practically cut off, and the total station is placed on a deck or a dock;
step S200, acquiring an included angle between a midship line and an emergent path through a total station;
and step S300, judging whether the included angle is in the range of 1-3 degrees, and if the included angle is in the range of 1-3 degrees, judging that the installation angle of the gangway lamp installed on the bow is qualified.
In the present embodiment, as shown in fig. 1, a relative positional relationship between the beam distribution range of the starboard lamp 8 and the traveling heading and starboard directions is shown in a case where the starboard lamp 8 is mounted in a qualified state, and in which the light emission intensity of the starboard lamp in the heading is indicated by a hatched portion to be reduced to a range of a definite cut-off light on the left side of the starboard lamp 8 defining the light arc.
In step S100, the mounting orientation of the laser lamp is required to satisfy the requirement that the emission path of the colored laser light be in a range where the emission intensity of the starboard lamp 8 on the left side of the prescribed light arc should be reduced to a practically cut-off light, or in a range where the emission intensity of the starboard lamp 7 on the right side of the prescribed light arc should be reduced to a practically cut-off light.
In steps S200 and S300, since if the installation angle of the laser lamp is acceptable, the zero degree arc edge line of the specified arc of the portlight needs to be parallel to the heading, that is, the zero degree arc edge line needs to be parallel to the midship line 1, and the outgoing path of the colored laser light moves synchronously with the portlight, it can be determined whether the installation position of the portlight is acceptable or not by detecting and examining the position where the outgoing path should be. Specifically, whether the zero degree light arc edge line of the portlight is parallel to the midship line is determined by determining whether the included angle between the emergent path and the midship line 1 is 1-3 degrees, so that whether the position of the emergent path is qualified or not is detected and verified by detecting and verifying the angle between the emergent path and the midship line 1, and whether the installation angle of the laser lamp is qualified or not can be determined.
It will be appreciated that if the resulting angle is not in the range of 1-3, then the mounting angle of the gangway lamp is unacceptable.
The method for checking the installation angle of the bow-mounted portlight 4 is convenient to operate, easy to implement and can be finished at the stage of the dock at the earliest.
In an alternative of this embodiment, the step S200 specifically includes the following steps:
step S210, selecting two reference points on a midship line or a dock wall central line parallel to the midship line, and acquiring coordinates of the two reference points through a total station;
step S220, selecting two positioning points on the emergent path, and acquiring coordinates of the two positioning points through a total station;
and step S230, calculating an included angle through the total station according to the coordinates of the two locating points and the coordinates of the two reference points.
In this embodiment, through the function of the "two straight line piece included angle" of the total station 5, wherein, the midship line 1 is represented by two reference points, the outgoing path is represented by two locating points, and the included angle can be calculated, so that the measurement accuracy is high, the operation is convenient, and the calculation is convenient.
In the alternative of this embodiment, two reference points are selected on the midship line in step S210, which specifically includes the following steps:
step S2110, marking a midship line parallel to a dock wall midline on a deck by referring to the dock wall midline through a total station in a dock stage;
step S2111, placing the total station on the dock or deck during the dock stage, or on the deck during the dock stage;
step S2112, selecting two reference points on the midship line, and acquiring coordinates of the two reference points by the total station.
In particular, the entire midship line 1 parallel to the wall midline can be marked on the deck 6 by reference to the wall midline by means of the total station 5. Alternatively, only two representative and easily observable reference points of the midship line 1 are marked on the deck 6, so that the step of selecting a reference point can be saved.
The method for selecting the first reference point 10 and the second reference point 11 on the midship line 1 can be implemented in a dock stage after marking the midship line 1, can also be implemented in a wharf stage, and is suitable for being used for easily marking the ship shape of the midship line 1 on the deck 6, namely, suitable for being used for the ship shape of a building without excessively obstructing the use of the total station 5 on the deck 6.
The dock wall midline is a common datum line formed on the side wall of the dock, and the construction of most structures of the whole ship body is based on the dock wall midline.
In an alternative of this embodiment, the step of selecting two reference points on the dock wall centerline in step S210 specifically includes the following steps:
in step S2120, in the dock stage, the total station is placed on the dock or deck, two reference points are selected, and coordinates of the two reference points are acquired by the total station.

In an alternative scheme of this embodiment, the distance between the first locating point and the second locating point is not less than 10m, so as to avoid insufficient characterization accuracy of the dock wall midline or midship line caused by too small distance between the first locating point and the second locating point.
Specifically, the distance between the left first positioning point and the left second positioning point is not less than 10m; the distance between the right first locating point and the right second locating point is not less than 10m.
