Example Embodiment
[0025] Example 1:
[0026] Such as figure 1 As shown, this embodiment includes a scanning device and an electronic control device connected to the scanning device. The electronic control device includes a computer and a motion controller connected to the computer, such as figure 2 As shown, the scanning device includes a mounting frame 1, a scanning frame 3 and a servo transmission mechanism 2. The scanning frame and the mounting frame are slidingly connected by the servo transmission mechanism, and a hydrophone 4 is installed on the scanning frame. CAN bus or wireless connection is used between the servo drive mechanism of the scanning device and the motion controller of the electric control device, and between the motion controller and the computer.
[0027] The servo transmission mechanism in this embodiment is composed of a motor 5 and a sliding block 6 fixedly connected to the scanning frame. The sliding block slides along the mounting frame under the drive of the motor to dri...
Example Embodiment
[0036] Example 2:
[0037] Such as image 3 As shown, the difference between this embodiment and embodiment 1 is that the scanning frame 3 adopts a vertical scanning frame, which is composed of a cantilever, a carbon fiber rod with a diameter of 16mm, and an aluminum alloy joint connecting the two. The carbon fiber rod uses a positioning pin It is screwed and fixed at the end of the cantilever. Considering that the strength of the joint directly affects the accuracy of the final scan, the joint is made of high-strength aluminum alloy instead of non-metallic materials. The distance between the hydrophones is 200mm, and the distance between the hydrophones and the apex of the arc on the side of the cabin is 200mm. The vertical scanning frame is mounted on the slider in a cantilever manner, and the motor driving force is first transmitted to the timing belt through the gear, and then transmitted to the cantilever end gear by the timing belt. The vertical movement is guided by the c...
Example Embodiment
[0038] Example 3:
[0039] This embodiment includes a scanning device and an electronic control device connected to the scanning device. The electronic control device includes a computer and a motion controller connected to the computer. The scanning device includes a mounting frame 1, a scanning frame 3 and a servo drive mechanism. 2. The scanning frame and the mounting frame are slidably connected by a servo drive mechanism, and the hydrophone 4 is installed on the scanning frame. CAN bus or wireless connection is used between the servo drive mechanism of the scanning device and the motion controller of the electric control device, and between the motion controller and the computer.
[0040] Such as Figure 4 As shown, the mounting frame of this embodiment is composed of two parallel guide rails. The guide rails are installed on the two guardrails of the submarine. The guardrails are provided with guide pads at intervals. When installing on site, the arranged guide pads must supp...
