Fishing boat inclination angle inspection device

Abstract

The invention discloses a fishing boat inclination angle inspection device, which belongs to the technical field of fishing boat inspection devices, the device comprises an inclination angle measurement assembly, and is characterized by further comprising a stabilization assembly, the stabilization assembly is arranged in a box body, the stabilization assembly comprises a driving gear, a transmission gear, a driven gear and a rack, the driving gear is matched with a rotating shaft. The transmission gear is rotatably matched with the inner wall of the box body through a transmission shaft, the driving gear is meshed with the transmission gear, a gear hole of the driven gear sleeves the outer side of the transmission shaft, the lower end of the rack is connected with the box body through a compression spring, and the rack is meshed with the driven gear; a circular groove is formed in one side of the driven gear, the rotating shaft is matched with a one-way wheel, a plurality of specially-shaped grooves are evenly distributed in the one-way wheel in the circumferential direction of the one-way wheel, and pin rollers are placed in the specially-shaped grooves of the one-way wheel. Compared with the prior art, the resistance can be synchronously changed along with the swing amplitude of the pendulum bob, and the measurement precision of the pendulum bob is improved.

Description

technical field [0001] The invention relates to the technical field of fishing boat inspection devices, in particular to a fishing boat inclination inspection device. Background technique [0002] Newly built fishing boats need to carry out inclination tests to determine the position of the center of gravity of the ship before delivery. In the existing test methods, it is usually necessary to use a pendulum to measure the inclination angle, but due to the influence of wind or waves, the pendulum will sway unstable, making the Hammer measuring tools are more difficult to carry out. [0003] Therefore, in the existing method, an oil tank is usually placed under the pendulum, and the oil tank is filled with high-viscosity heavy oil, and the pendulum is gradually stabilized by utilizing the liquid resistance of the high-viscosity heavy oil. However, heavy oil is used to stabilize the pendulum. Due to the unstable wind force on the water surface during the actual test, heavy oil...

Problems solved by technology

However, heavy oil is used to stabilize the pendulum. Due to the unstable wind force on the water surface during the actual test, heavy oil with different viscosities is often required, which increases the difficulty of the test. Moreover, heavy oil has a strong smell, high viscosity, and difficult installation of test equipment, which often pollutes the deck test area.

[0004] The invention patent "A device and method for measuring ship inclination" (application number: 2018109974407) discloses a pendulum stabilized by magnetic force generated by a magnetic force generator. The magnetic force generated by the magnetic force generator is constant, so when the pendulum swings , the amplitude gradually becomes smaller, the magnetic force generated by the magnetic force generating device remains unchanged, which will affect the accuracy of the pendulum
