A tool for accurate reading of ship's underwater water gauge

Abstract

The purpose of the present invention is to solve the existing problem that it is difficult to accurately read the water gauge, and discloses a tool for accurately reading the underwater water gauge of a ship, including a scale. A connecting block is installed on the left side of the scale. A suction plate is installed on the left side of the connection block, a fastening screw is installed between the suction plate and the connection block, a support frame is installed on the top of the scale, a collar is installed on the top of the support frame, and a collar is set inside the collar. The second rotating shaft, the front end of the second rotating shaft is equipped with a first motor, the surface of the second rotating shaft is equipped with a turntable, the upper side of the scale is equipped with a guide ring, and the inside of the scale is longitudinally provided with a guide groove. The invention rationally utilizes the driving force of the second motor to rotate the fan blades to generate a spiral force, thereby reducing wave errors and external influences when taking readings near the scale, thereby better obtaining the draft of the ship. And the design is reasonable, the operation is convenient, and it is worth promoting.

Description

technical field [0001] The invention relates to the field of ship water gauges, in particular to an accurate reading tool for ship underwater water gauges. Background technique [0002] Water gauges are widely used in soft soil foundation treatment, port and wharf projects to observe changes in groundwater levels and ocean tidal levels. The product has the characteristics of stable reading, anti-interference and long life, and is adopted by major domestic and foreign key projects. [0003] After the ship is built, it is necessary to carry out an inclination test to determine the light ship weight and center position of the ship. Patent CN201110282300.X provides a device for ship draft measurement, which includes a cuboid container with a hole at the bottom and a laser distance measuring device for vertical irradiation and horizontal plane at the top. The device obtains the measured value of the draft by measuring the distance between the buoy and the top of the container. ...

Patent CN201110282300.X provides a device for ship draft measurement, which includes a cuboid container with a hole at the bottom and a laser distance measuring device for vertical irradiation and horizontal plane at the top. The device obtains the measured value of the draft by measuring the distance between the buoy and the top of the container. However, the container needs to be suspended on the side of the ship. As long as there are waves, the container will tilt, which will affect the accurate reading and cause errors in the reading. Moreover, the existing Although the container is used to cover the measuring ruler, it will also affect the observation of the measuring ruler when the water waves are large, thereby affecting the accurate reading of the measuring ruler and the accurate measurement of the draft of the ship. Therefore, it is urgent to design a ship Accurate reading tool of underwater water gauge to solve the deficiencies of existing technologies
