[0001] The invention relates to the technical field of industry, in particular to a portable online shaft power measurement and calibration device. Background Art

[0002] The fixed shaft power meter installed on the ship cannot be dismantled and sent to the designated agency for calibration regularly because the ship is at sea for a long time and the maintenance period is relatively short. If the calibration is carried out during the docking or minor repair stage, the metrological effectiveness of the ship-mounted equipment is often exceeded. Therefore, an online shaft power synchronous measurement device is designed to test the fixed shaft power meter without affecting the detection of the fixed equipment during the voyage of the ship. Therefore, people need a portable shaft power online measurement and calibration device to solve the above problem. Summary of the invention

[0006] The installation test assembly includes a fixing seat, a connecting plate, an auxiliary stabilizing plate, an auxiliary stabilizing block, a rotation speed sensor, and a signal transmission antenna. The fixing seat is located at the bottom of the installation test assembly. The fixing seat is a connecting component between the installation test assembly and the movable assembly, and can keep the first connecting rod and the connecting plate relatively fixed, which is beneficial to the stability of the entire device and avoids the poor stability of the device, resulting in inaccurate sensor test results or affecting the signal of the signal transmission antenna. A connecting plate is fixedly installed above the fixing seat, and the connecting plate supports the signal transmission antenna so that the signal transmission antenna will not shake and avoid affecting the wireless signal. The connecting plate also supports the auxiliary stabilizing plate to avoid contact with the auxiliary stabilizing plate The auxiliary stabilizing block produces shaking, which in turn affects the operation effect of the speed sensor. An auxiliary stabilizing plate is fixedly installed on the side of the connecting plate, and the auxiliary stabilizing plate supports the auxiliary stabilizing block. An auxiliary stabilizing block is fixedly installed above the auxiliary stabilizing plate, and the auxiliary stabilizing block fixes the speed sensor, which is beneficial to the normal operation of the speed sensor. A speed sensor is fixedly installed in the auxiliary stabilizing block, and the speed sensor detects the external ship shaft system and sends the shaft system speed data to the external signal receiving device through the signal transmission antenna. A signal transmission antenna is fixedly installed on the upper end of the connecting plate, and the signal transmission antenna plays a role of signal transmission, and is responsible for transmitting the sensor and the external signal transmitting / receiving device.

[0007] The movable component includes a first connecting rod, a first fixed block, a second fixed block, a second connecting rod, a locking strip, and an auxiliary rotating rod. The first connecting rod is fixedly installed at the bottom end of the fixed seat. The first connecting rod plays the role of connecting and installing the test component and the movable component. The first connecting rod is fixedly installed at one end away from the fixed seat. The first fixing block plays the role of fixing the first connecting rod so that the first connecting rod can be rotatably fixed with the second fixing block. The second fixing block is installed above the first fixing block. The second fixing block and the first fixing block can rotate on the same axis, so that the first connecting rod and the second connecting rod can rotate with the rotation axis of the second fixing block and the second fixing block as the axis, which is convenient for the fixing operation of the device and makes the C-type The fixing assembly can be fixed at different positions on the ship by utilizing the rotation effect of the second connecting rod, making the fixing operation more flexible and changeable. A second connecting rod is horizontally penetrated inside the second fixing block. The second connecting rod is a connecting component between the movable assembly and the C-type fixing assembly. When the pressure of the locking strip on the second fixing block is reduced, the second connecting rod can be drawn back and forth in the second fixing block, so that the distance between the C-type fixing assembly and the installation test assembly can be adjusted, which is beneficial to the flexibility of the fixing position of the C-type fixing assembly. A locking strip is installed from the top of the second fixing block. The middle part of the locking strip is clamped on the upper surface of the second fixing block by a clamping ring. The bottom of the locking strip is rotatably installed on the top of the first fixing block by a thread.

When the second fixing block rotates clockwise, the locking strip moves downward relative to the first fixing block using the bottom thread, so that the pressure on the second fixing block located between the locking strip and the first fixing block increases. At this time, the locking strip, the second fixing block, the second connecting rod, and the first fixing block are locked. The space between the first and second fixed blocks is compressed, and neither the rotation between the first fixed block and the second fixed block nor the lateral pulling operation of the second connecting rod inside the second fixed block can be performed. At this time, the positional relationship between the C-type fixed component, the movable component and the installation test component is fixed. The C-type fixed component has a good stabilizing effect on the installation test component, which is beneficial to the accuracy of detection data and the stability of signal transmission. An auxiliary rotary rod is fixedly installed on the top of the locking strip, and the auxiliary rotary rod plays a role in assisting the rotation of the locking strip.

One end of the second fixing block is inserted into the fixing hole, and a hexagonal screw is used to pass through the screw hole to penetrate the two parts divided by the transverse groove into an upper and a lower part, and then the hexagonal nut and the hexagonal screw are tightened. In this case, the space of the transverse groove is reduced, and the space of the fixing hole is also reduced accordingly, and then the fixing effect of the fixing hole on the second fixing block is also strengthened. On the contrary, the hexagonal nut and the hexagonal screw are loosened, the space range of the fixing hole is expanded, and the fixing effect of the fixing hole on the second fixing block is deteriorated. At this time, the second fixing The fixed block can be moved out from the fixing hole to facilitate the disassembly and assembly of the device.
