Description

Technical Field

[0001] This invention relates to the field of ship testing equipment technology, and more specifically to a ship pitch simulation device. Background Technology

[0002] As humans continue to develop marine resources, various marine sensors are being mounted on ships to detect and collect marine data. Due to the influence of waves in the ocean, ships will experience pitching motion, which will affect the accuracy and data accuracy of the mounted sensors. Therefore, a large amount of experimental data is needed to enable the sensors to adapt to the effects of the ship's pitching motion.

[0003] However, most traditional experimental methods involve using sensors mounted on ships to conduct experiments directly. This method is greatly affected by environmental factors, makes it difficult to obtain regular data, and has a long experimental cycle. It is not only cumbersome but also expensive.

[0004] Therefore, providing a ship pitch simulation device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a ship pitch simulation device that is simple to operate, easy to manufacture, low in cost, and capable of obtaining regular experimental data.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ship pitch simulation device, comprising:

[0008] A water tank, wherein the top of the water tank is open and a water storage tank is formed therein;

[0009] A synchronous belt linear guide slide is mounted on the top of the water tank by a plurality of first screws;

[0010] An underwater gimbal, wherein the underwater gimbal is slidably mounted on the bottom of the synchronous belt linear guide slide table via a connecting frame;

[0011] The mounting platform is rotatably mounted on the underwater gimbal; the mounting platform has sensor mounting holes of at least one shape.

[0012] By adopting the above solutions, the beneficial effects of the present invention are:

[0013] The underwater gimbal simulates the straight-line navigation and pitching motion of a ship by using the linear motion of the underwater gimbal on the synchronous belt linear guide slide and the rotational motion of the platform driven by the underwater gimbal. The equipment is small in size, easy to manufacture, and simple to operate, making it convenient to conduct experiments on the ship's onboard sensors and obtain regular experimental data.

[0014] Furthermore, the connecting frame includes a frame body, a slider, a slider connector, and two crossbeams;

[0015] The slider is mounted on the top of the frame body via the slider connector; the slider is slidably mounted on the bottom of the synchronous belt linear guide slide table.

[0016] The two crossbeams are fixed to the bottom of the frame body respectively.

[0017] The beneficial effects of adopting the above-mentioned further technical solution are that the slider drives the frame body to move horizontally on the synchronous belt linear guide slide to simulate the navigation of a ship on the water surface. The connection structure is stable and facilitates the acquisition of accurate data.

[0018] Furthermore, the frame body, the slider connector, and the crossbeam are all made of aluminum alloy.

[0019] The beneficial effects of adopting the above-mentioned further technical solutions are that they have strong plasticity, good productivity, and great advantages in production.

[0020] Furthermore, the underwater gimbal includes a gimbal body, a gimbal connecting flange, and a gimbal connecting plate; the gimbal connecting flange is mounted on the top of the gimbal body by a plurality of second screws; the gimbal connecting plate is mounted on the top of the gimbal connecting flange by a plurality of third screws; both crossbeams are connected to the gimbal connecting plate by a plurality of fourth screws.

[0021] Furthermore, the mounting platform includes a base plate, a first fixed side plate, a second fixed side plate, a transmission flange, and a stop;

[0022] The sensor mounting holes are formed on the base plate; the first fixed side plate and the second fixed side plate are symmetrically mounted on both sides of the top plane of the base plate by bolts and adapter nuts arranged in double rows; the first fixed side plate has a first through hole; the second fixed side plate has a second through hole;

[0023] The transmission flange is mounted on the outer side of the first fixed side plate by multiple transmission flange connecting nails, and the center of the transmission flange is distributed corresponding to the center of the first through hole;

[0024] One end of the gimbal body is installed in the first through hole through a first lubrication ring, and the spline shaft of the gimbal body is fixedly connected to the transmission flange through a spline; a transmission flange fixing nail is provided in the center of the transmission flange and fixedly connected to the spline shaft; the other end of the gimbal body has a protruding cylinder installed in the second through hole through a second lubrication ring; the stop is threadedly installed on the extension end of the protruding cylinder.

[0025] The beneficial effects of adopting the above-mentioned further technical solution are as follows: 1) The spline shaft at one end of the gimbal body is fixedly connected to the transmission flange, thereby driving the transmission flange to rotate, which in turn drives the first fixed side plate fixedly connected to the transmission flange to rotate. The protruding cylinder at the other end of the gimbal body is installed in the second through hole through the second lubrication ring, thereby realizing the relative rotation between the gimbal body and the second fixed side plate to simulate the pitching motion of a ship; 2) The stop is threadedly installed at the extension end of the protruding cylinder, and a transmission flange fixing nail is set in the center of the transmission flange to prevent the axial movement of the gimbal body; 3) The double-row distributed bolts and matching nuts can ensure the stability of the connection and prevent the first fixed side plate and the second fixed side plate from twisting on the base plate.

[0026] Furthermore, both the first lubricating ring and the second lubricating ring are made of polytetrafluoroethylene.

[0027] The beneficial effect of adopting the above-mentioned further technical solution is to ensure the relative rotation between the gimbal body and the first fixed side plate and the second fixed side plate.

[0028] Furthermore, the base plate, the first fixed side plate, the second fixed side plate, and the transmission flange are all made of titanium alloy.

[0029] The beneficial effects of adopting the above-mentioned further technical solutions are that they reduce weight while meeting strength requirements and improving corrosion resistance. Attached Figure Description
