Description

Technical Field

[0001] The utility model relates to the technical field of ship draft depth measurement, in particular to a draft depth measurement device for ship navigation. Background Art

[0002] Ship draft detection is an important part of ensuring the safe operation of ships. It involves measuring the sinking depth of the ship on the water surface, that is, the vertical distance from the bottom of the ship to the water surface, adjusting the ship's cargo capacity in time according to the draft depth, selecting the maximum carrying capacity under safe conditions, and improving the ship's carrying capacity. Ship draft depth measurement is usually achieved manually or with various detection instruments.

[0003] When measuring the draft depth of existing ships, if the sea surface is not calm, it is not easy to intuitively understand the draft depth due to the influence of waves. The ups and downs of waves will also affect the accuracy of the detection instrument, resulting in poor accuracy of the measured values. In addition, if the draft gauge is used for measurement, such as a measuring tool that needs to be immersed in seawater, long-term immersion will cause erosion to the draft gauge, resulting in a short service life of the draft gauge. Utility Model Content

[0004] The utility model aims to provide a draft depth measuring device for ship navigation to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Furthermore, a nozzle is fixedly installed on the water outlet of the first water pump through a water pipe, and a drainage pipe penetrating the measuring cylinder is fixedly connected to the water outlet of the second water pump, and a one-way valve is fixedly installed inside the drainage pipe.

[0009] Furthermore, a gear ring is fixedly installed at the upper end of the inner surface of the isolation cover, and a No. 1 motor is fixedly installed at the upper end of the inner surface of the measuring cylinder.

[0010] Preferably, a No. 1 gear is fixedly mounted on the output end of the No. 1 motor, and the No. 1 gear is movably meshed with the ring gear.

[0011] Furthermore, a connecting ring is fixedly installed on the upper end of the spiral blade, a rotating shaft is fixedly installed on the upper surface of the connecting ring, a fixing ring is rotatably connected to the outer side of the rotating shaft, and the fixing ring is fixedly connected to the mounting ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The No. 1 gear is driven to rotate by the No. 1 motor, which is used for meshing transmission with the ring gear. The ring gear drives the isolation cover to rotate, exposing and isolating the filter screen, so that the inside of the measuring tube is in contact with and isolated from the sea water, thereby isolating the measuring area from the surrounding sponge through the measuring tube. When the sea surface is not calm, the ups and downs of the waves can be avoided to affect the accuracy of the detection instrument, which is convenient for intuitively understanding the draft depth and improving the accuracy of the measured value.

[0015] 2. When the measuring device is a measuring tool such as a draft gauge that needs to be immersed in seawater, the draft depth of the ship is visually observed through the calm water surface inside the measuring tube, and the No. 1 water pump is connected to fresh water. After the measurement is completed, the No. 2 water pump is operated to discharge the seawater inside the measuring tube, and the No. 1 water pump is operated to spray fresh water into the measuring tube through the nozzle. Then the No. 2 motor is operated, and the meshing transmission of the No. 2 gear drives the spiral blade to reciprocate. The brush sweeps across the inner wall of the measuring tube to clean it and washes away the adhering seawater, so that it is easy to clean it through the cleaning component to avoid erosion of the draft gauge caused by long-term immersion and increase the service life of the draft gauge.
