Description

Waterline change correction system to reduce surveying error of marine surveying line}

Marine survey ships are ships equipped with various instruments to perform observation, measurement and various missions of the ocean.

Among these, marine survey ships are also commonly referred to as waterway survey ships, and are based on surveys, waterway surveys, and cadastral laws, for the purpose of maritime traffic safety, marine conservation and use development, marine jurisdiction, and marine disaster prevention, A vessel used for surveying the Earth's magnetism, gravity, topography, geology, coastline and accompanying land.

In particular, such a waterway survey is very important to investigate in advance in order to accurately display the obstacles in the critical waterway and harbor entrance in case of emergency.

However, there is a problem in that the measurement accuracy is lowered according to the change of the draft line as the oil is used as compared to the draft line when the oil survey is filled and the survey starts.

In addition, due to the change in the center of gravity, when the marine survey ship is rolled back and forth or the center of gravity is tilted to one side, the measurement failure is caused, it is not possible to obtain accurate data.

In the draft line change correction system for reducing the measurement error of the marine survey line according to the present invention, as shown in Figure 1, the seawater tank 110 is installed on the rear side of the hull 100.

At this time, the seawater tank 110 is connected to the pump (not shown) is configured to fill or discharge the seawater.

In addition, a center of gravity detection sensor 120 is installed at the inner center of the hull 100.

The center of gravity detection sensor 120 sucks the seawater as much as the weight into the seawater tank 110 in order to prevent the hull 100 from rising by the weight decrease as the fuel used to propel the hull 100 is reduced. It is a sensor used to calculate and manage weight so that it can

In addition, the controller 130 is installed in the control tower 140, by operating the pump in accordance with the detection signal of the center of gravity detection sensor 120 to fill the seawater into the seawater tank 110 or inside the seawater tank 110 Drain the water so that the water line stays the same at all times.

Therefore, it is possible to maintain surveying accuracy during waterway survey.

In addition, in the present invention, the hull 100 may further include a front and rear weight center adjusting unit 200 as shown in FIG. 2.

The front and rear weight center control unit 200 is to supplement the control function of the seawater tank 110, a kind of ballast water control method through the seawater tank 110 takes a lot of time and must be adjusted to a quantitative part quickly, Falls in accuracy.

Because of this, when the seawater tank 110 is installed on the stern side of the hull 100, when the center of gravity of the hull 100 is distorted, the hull 100 may roll back and forth.

The front and rear weight center control unit 200 may be installed at intervals up and down so as not to interfere with the weight center sensor 120 so as to quickly solve the problem.

The front and rear weight center control unit 200 is installed in the center of the length, in particular the center of gravity of the hull 100, and includes a slide base 210 as shown in Figures 2 and 3 examples.

The slide base 210 is a plate member formed in a 'U' shape, and is a means for guiding the first and second sliding blocks 220 and 222 to move smoothly without external interference.

In addition, first and second motors 230 and 232 are installed at both ends of the slide base 210 at intervals, respectively, and first and second ball screws 240 and 242 on each motor shaft of the first and second motors 230 and 232. Are connected and fixed, respectively, and end portions of the first and second ball screws 240 and 242 are rotatably supported to be rotated in place by bearings, although not shown.

In this case, the first and second ball screws 240 and 242 are installed through the first and second sliding blocks 220 and 222, respectively, wherein the first ball screw 240 is screw-coupled with the first sliding block 220, That is, the tooth coupling is installed and the second sliding block 222 is installed through just passing through without screwing.

Similarly, the second ball screw 242 is installed to be screwed, that is, tooth-engaged with the second sliding block 222 and the first sliding block 220 is installed through just passing through without screwing.

Therefore, the first and second sliding blocks 220 and 222 may be installed in the same line, that is, in-line, all of them are heavy, and the initial state, that is, the home position, with the same distance apart from the center of gravity of the hull 100. Stays in the state.

Then, a difference occurs in the center of gravity, and when the controller 130 senses this, the seawater tank 110 adjusts the amount of seawater and simultaneously rotates the first and second motors 230 and 232 to make the first and second sliding blocks. By adjusting the position of (220,222) very easily and quickly the center of gravity of the hull 100 can be immediately corrected.

In this way, the center of gravity of the hull 100 in the front and rear direction is stabilized, and the waterline is subsequently adjusted through the seawater tank 100 to allow stable operation and accurate measurement.

In this case, for smooth sliding of the first and second sliding blocks 220 and 222, a pair of hemispherical grooves HOM are formed on the bottom surfaces of the blocks, and balls BAL are inserted into the hemispherical grooves HOM. The ball BAL is supported so as not to be separated by the ball cover COV, and a part of the ball BAL is exposed through the ball hole HL formed in the ball cover COV, and the exposed ball BAL is exposed. A part of) is brought into contact with the upper surface of the slide base 210 so that the first and second sliding blocks 220 and 222 are in contact with the slide base 210 with minimal frictional force, thereby enabling smooth sliding.

In addition, in the present invention, as shown in Figure 4, the hull 100 is further installed in the upper end of the outer peripheral wall of the hull 100 to prevent the collision with the mooring when mooring the moored after entering the port hull 100 It can be configured to enhance the effect of preventing breakage.

Usually, the tires are tying up, but the appearance is unsightly, and if the ropes are weakly tied, the tires move and are not in place, sometimes causing damage due to collision with the mooring.

In the present invention, to solve such a problem, the first rubber plate spring 310 is convexly fixed to the outer wall of the hull 100 and the second rubber plate spring 320 is in contact with the first rubber plate spring 310. The second rubber plate spring 320 has a circular cross section that is tightly fixed to the outer wall of the hull 100 in a housing shape completely surrounding the first rubber plate spring 310. It is fixed to the inner wall of the rubber cover 330.

Then, when the external force acts or collides with the object, the rubber cover 330 is primarily deformed to be primarily elastically deformed, and then the second rubber plate spring 320 is secondly deformed to be secondaryly deformed as the second deformed material. Since the first rubber plate spring 310 is elastically buffered in the third manner as the third deformation, the perfect elastic absorption buffer is made to keep the hull 100 even more secure and improve appearance quality.
