Problems solved by technology

[0002] When carrying out related experiments on the ship model in the ship model towing pool, usually, only four screws are used to connect the balance and the bottom connecting plate of the ship, and the direction of the ship model is determined by visual observation. However, this installation method has many problems. large human error
If the direction of the ship model deviates slightly, it will cause a certain angle between the ship model and the forward direction when it moves under the traction of the trailer, which will make the measured results inaccurate, and it is easy to cause in the test of the ship model with high speed and large scale. The ship model is deflected, the balance is damaged

Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0020] Combine figure 1 only Picture 9 , The present invention is a set of multifunctional ship model direction calibration device, including horizontal bracket, square telescopic rod, one-line light source laser, 360 degree dial, level bubble and three-way joint and other main components, adopting detachable combined structure , Parts can be replaced according to needs to adapt to different needs, and at the same time easy to store. The horizontal bracket includes a square horizontal rod 1, two square short telescopic rods 2, a trapezoidal card slot 3, and a square card slot 4. The end of the horizontal rod is welded to the end of the short telescopic rod to make the two slots The center line is parallel and perpendicular to the axis of the horizontal rod, and the two grooves are welded to the other end of the short telescopic rod. The two grooves c...

Abstract

The invention provides a multifunctional ship model direction calibration device which comprises a horizontal bracket, a square telescopic rod, a horizontal straight line light source laser device, a 360-degree dial, a bubble level, T joints and other main components. Aiming at different test and precision requirements for a ship model towing tank, the multifunctional ship model direction calibration device is designed to be a detachable combined type structure; by replacement of used parts, the multifunctional ship model direction calibration device can conform to the ship model direction calibration work at the initial stage of an experiment such as a ship model resistance test, a seakeeping test, a self-propulsion test and a roll damping test. The multifunctional ship model direction calibration device is overall mounted on a side bridge of a towing tank trailer, can provide a reference for a mounting direction of a ship model and improve the mounting precision and is wide in application range and low in manufacturing cost.

Description

Technical field [0001] The invention relates to a multifunctional ship model direction calibration device, which belongs to the field of experimental equipment. Background technique [0002] When carrying out related experiments of the ship model in the ship model towing pool, usually, four screws are used to connect the balance and the bottom connecting plate of the ship, and the direction of the ship model can be determined by visual observation. However, this installation method has many problems. Large human error. A slight deviation of the direction of the ship model will cause the ship model to have a certain angle with the forward direction when it is towed by the trailer, making the measured result inaccurate, and it is very easy to cause it in the ship model test with high speed and large scale. The ship model is deflected and the balance is damaged. Considering the problems existing in the current experiment process, a design scheme of this multifunctional ship model ...
