Problems solved by technology

Due to the particularity of the structure of the semi-submerged propulsion device, it cannot be directly measured with conventional angle measurement tools
The projection measurement method can be used to measure the rudder angle and pitch angle, but the operations such as lighting, hanging vertical lines, and laying paper are cumbersome, inefficient, and have large measurement errors

Embodiment Construction

[0019] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like Figure 1-5 As shown, the angle measuring tooling of the semi-submerged propulsion device of the present embodiment includes a strip-shaped positioning plate 10 and a strip-shaped adjusting plate 20, and a strip-shaped hole 11 is provided on the surface of an end plate of the positioning plate 10, and the strip-shaped hole 1 The hole length direction of 11 is consistent with the plate length direction of positioning plate 10, and strip hole 2 21 is offered on the plate surface of adjustment plate 20, and positioning plate 10 and adjustment plate 20 plate surfaces stick together, and strip hole one 11 and strip hole two 21 are cross-arranged and fixed by bolts 30 to realize the detachable connection between the positioning plate 10 and the adjusting plate 20. A right-angled notch is opened at one of the corners of the other end ...

Abstract

The invention relates to the technical field of angle measurement of a semi-submerged propulsion device, in particular to a tool for measuring the angle of a semi-submerged propulsion device and a measuring method, which includes a positioning plate and an adjustment plate. The second strip hole is set on the surface of the board. The first strip hole and the second strip hole are arranged crosswise and fixed by bolts to realize the detachable connection between the positioning plate and the adjustment plate. One of the corners of the other end of the positioning plate Open a right-angled notch, one of the sides of the right-angled notch is the working side 1, the length direction of the working side 1 is consistent with the length direction of the positioning plate, and one side of the positioning plate is vertically outward along the width direction of the positioning plate Extend to form a convex plate, one of the sides of the convex plate is the second working side, the second working side and the first working side are parallel to each other, the adjustment plate is T-shaped, and the end edge line of the T-shaped end of the adjustment plate is the third working side, which can be adjusted Efficient and accurate angle measurement for different models of semi-submerged propulsion units.

Description

technical field [0001] The invention relates to the technical field of angle measurement of a semi-submerged propulsion device, in particular to a tool for measuring the angle of a semi-submerged propulsion device and a measuring method. Background technique [0002] Semi-immersed paddle propulsion device (also known as surface paddle propulsion device), has the characteristics of no cavitation erosion, low resistance, shallow draft and high efficiency when sailing at high speed. It is the preferred propulsion method for new high-speed boats in the world today. A large number of applications such as military ships, official ships and hydrographic ships. The rudder angle and pitch angle of the semi-submerged propulsion device are key indicators, which need to be tested during the development and production process. Due to the particularity of the structure of the semi-submerged propulsion device, it cannot be directly measured with conventional angle measurement tools. The ...
