Description

Technical Field

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

[0002] The draft of a ship, referred to as draft, refers to the deepest length of the part of the ship that sinks underwater in the water. Different ships have different drafts. By measuring the draft, we can accurately determine whether the ship is overloaded, so it is necessary to measure the draft of the ship.

[0003] After searching, in the prior art, the Chinese patent with patent announcement number CN211893594U discloses "a ship draft depth measuring device that is easy to disassemble, including a motor fixed to the edge of the ship's clamping plate, the output shaft of the motor is connected to a winding roller through a coupling, the surface of the winding roller is wound with a connecting rope, the end of the connecting rope is connected to a detection hose, an ultrasonic probe is provided on the inner top of the detection hose, a tubular anchor is connected to the bottom of the detection hose, water inlets are provided on both sides of the tubular anchor, the top of the tubular anchor is connected to the bottom of the detection hose, an L-shaped bracket is connected to one end of the winding roller, a limiting hole adapted to the detection hose is provided at the bottom of the L-shaped bracket, a filter is provided at the connection between the detection hose and the tubular anchor, a spherical buoy is provided above the filter, this utility model can measure the distance h between the ship deck and the water surface, and the distance H from the ship deck to the bottom of the ship is fixed, and the draft D can be calculated by Hh", but there are still the following defects:

[0004] However, when the device is winding the connecting rope, the winding roller cannot be adjusted in position, so that the connecting rope is always wound at the same position, resulting in a continuous increase in the diameter of the winding of the connecting rope, causing the connecting rope to separate from the winding roller, resulting in reduced winding efficiency;

[0005] However, when the device is in use, the detection hose is limited by an L-shaped bracket, but the diameter of the L-shaped bracket is larger than the connecting rope. When the connecting rope is rolled up, the detection hose cannot accurately enter the interior of the L-shaped bracket, thereby failing to achieve the limiting effect on the detection hose.

[0006] Therefore, we make improvements to this and propose a ship's draft depth measuring device. Utility Model Content

[0007] The purpose of the utility model is to address the problem that a draft depth measuring device of a ship currently exists, in which the winding roller cannot be adjusted in position when winding the connecting rope, so that the connecting rope is always wound at the same position, resulting in a continuous increase in the diameter of the winding of the connecting rope, thereby causing the connecting rope to separate from the winding roller, resulting in reduced winding efficiency.

[0008] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0009] The ship's draft depth measuring device is used to improve the above problems.

[0010] The utility model is specifically as follows:

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] In the solution of the utility model:

[0021] 1. The measurement mechanism is set up to measure the draft of the hull. In the measurement mechanism, the user can make tees of different lengths according to their actual needs, and then put the tee into the water. At this time, water enters the interior of the tee through both ends of the tee, so that the float floats up. At this time, the ultrasonic sensor senses the distance between the float and the top of the hull, and then the draft of the hull can be detected by subtracting the distance between the float and the ultrasonic sensor from the height of the hull. When winding the connecting rope, the winding wheel is rotated while the slider is moved, so that the connecting rope is evenly wound on the winding wheel, which solves the problem of the connecting rope detaching from the winding roller in the prior art, resulting in reduced winding efficiency;

This solves the problem in the prior art that the detection hose is limited by an L-shaped bracket when in use, but the diameter of the L-shaped bracket is larger than the connecting rope. When the connecting rope is reeled in, the detection hose cannot accurately enter the interior of the L-shaped bracket, thereby failing to achieve the limiting effect on the detection hose.

[0035] like Figure 1-6 As shown, this embodiment provides a device for measuring the draft of a ship, comprising a hull 1, a measuring mechanism 2 for measuring the draft of the hull 1 is disposed on the top of the hull 1, and a stabilizing component 3 for improving the stability of the measuring mechanism 2 is disposed outside the hull 1;

When winding the connecting rope 202, the winding wheel 201 is rotated while the slider 205 is moved, so that the connecting rope 202 is evenly wound on the winding wheel 201 to prevent the connecting rope 202 from being wound too large, thereby preventing the connecting rope 202 from being knotted or detached from the winding wheel 201.

[0037] like Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the stabilizing assembly 3 includes a connecting rod 301 and a limiting ring 302, the connecting rod 301 is bolted to the side wall of the hull 1, the limiting ring 302 is welded to one end of the connecting rod 301, the connecting rope 202 is located inside the limiting ring 302 and is slidably connected to the limiting ring 302, when the connecting rope 202 is reeled in, the connecting rope 202 will move along the limiting ring 302, thereby improving the efficiency of reeling in the connecting rope 202.

[0038] like Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, one end of the winding wheel 201 is rotatably connected to the mounting plate 4, one end of the winding wheel 201 is bolted to the circular plate 5, the side wall of the circular plate 5 is rotatably connected to the crank 6, and the bottom of the mounting plate 4 is bolted to the top of the hull 1. By arranging the mounting plate 4, the circular plate 5 and the crank 6, the winding wheel 201 can be rotated more conveniently, thereby improving the efficiency of winding the connecting rope 202.

By providing the anti-corrosion layer, the three-way pipe 208 can be prevented from being corroded, thereby improving the service life of the three-way pipe 208.

[0043] Specifically, when the draft depth measuring device of the ship is in use: the user manufactures the length of the top of the tee 208 according to his actual needs. When measuring the draft depth of the hull 1, the tee 208 is normally located underwater, and water enters the interior of the tee 208 through both ends of the tee 208, and then contacts the float 210, so that the float 210 floats to the water surface and is flush with the water surface. The exhaust groove 211 can exhaust the air inside the tee 208. At this time, the ultrasonic sensor 212 can measure the distance between the float 210 and the top of the hull 1. , and the user collects and displays the data of the ultrasonic sensor 212 through an external microcontroller, and then the user subtracts the measured distance from the total height of the hull 1 to calculate the draft of the hull 1. After the measurement is completed, the winding wheel 201 is rotated while the extension rod 9 and the slider 205 are moved back and forth in a timely manner, so that the connecting rope 202 slides along the limiting ring 302. By moving the extension rod 9 and the slider 205 back and forth in a timely manner, the connecting rope 202 will not be accumulated into a circle with a larger diameter, thereby preventing the rope circle from escaping from the winding wheel 201 due to its larger diameter.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
