Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a ship balance testing device. Background Art

[0002] The ship balance test device for tilting the hull usually refers to the ship inclinometer, which is a device used to measure the tilt state of the ship. Its main purpose is to determine whether the hull is stable. The ship inclinometer plays a very important role in the navigation of the ship. Due to factors such as waves and wind, the hull is prone to tilt, which not only affects the speed and stability of the ship, but also poses a threat to the safety of the entire ship. Therefore, through the monitoring of the ship inclinometer, the tilt state of the hull can be understood in real time, so that corresponding measures can be taken to ensure the safety of the ship.

[0003] At present, in the existing technology, most of the balance test devices cannot adjust the position of the counterweight. If it is on a small boat, the small boat will sway greatly in the wind and waves, so the detector can easily exceed the range. On a large ship, the impact of wind and waves is smaller, although it is difficult to produce large swings, it is difficult for the detection device to detect. In view of this, we propose a ship balance test device. Utility Model Content

[0004] The main purpose of the utility model is to provide a ship balance test device, which can solve the problems raised in the above technical background.

[0007] Preferably, the counterweight pendulum includes a shell, the inner wall of the shell is slidably connected to the surface of the pointer rod, the inner wall of the shell is slidably connected to the surface of the fixed block, and the surface of the fixed block is provided with positioning teeth that cooperate with the surface of the pointer rod.

[0008] Preferably, the surface of the fixing block is fixedly connected to both ends of the spring sheet, the surface of the spring sheet is fixedly connected to the inner wall of the shell, the back of the fixing block is fixedly connected to a handle, and the surface of the handle is slidably connected to the inner wall of the shell.

[0009] Preferably, the device body comprises a fixed platform, a fan-shaped plate is fixedly connected to the front side of the fixed platform, and an inner wall of the fan-shaped plate is rotatably connected to the surface of the rotating shaft.

[0010] Preferably, a scale bar is provided on the surface of the fan-shaped plate, a baffle is fixedly connected to the surface of the fan-shaped plate, and a photosensitive plate is fixedly connected to the upper surface of the baffle.

[0011] Preferably, a light shielding plate is fixedly connected to the upper surface of the baffle.

[0012] Beneficial Effects

[0013] The utility model provides a ship balance test device, which has the following beneficial effects:

[0014] (1) The ship balance test device has a counterweight pendulum. When it is necessary to adjust the swing structure according to the hull, if the hull is small, the handles are pulled toward both ends so that the handles pull the fixed blocks apart to compress the spring sheet and push the counterweight pendulum upward, thereby reducing the pointer rod force arm and making the pointer rod swing smaller, thereby increasing the detection range of the detection device; if the hull is large, the counterweight pendulum is pulled down to increase the pointer rod force arm and make the pointer rod swing larger, thereby increasing the detection accuracy of the detection device.

[0015] (2) The ship balance test device uses a laser emitter. When the hull shakes, the pointer rod slides under the drive of the counterweight pendulum. If the swing amplitude of the pointer rod is small, the laser emitter cannot be moved out of the light-shielding plate, thereby avoiding interference caused by the vibration of the hull. If the swing amplitude of the pointer rod is large, the laser emitter moves out of the light-shielding plate and moves on the surface of the photosensitive plate, thereby stimulating the photosensitive plate, so that the swing amplitude and number of the hull are recorded, which is convenient for subsequent testing.
