TECHNICAL FIELD
[0001] The present application belongs to the field of marine equipment release and recovery, and particularly relates to a water vehicle blocking system. BACKGROUND
[0002] A water unmanned vehicle is an unmanned ship that can autonomously navigate on water and perform various tasks such as marine exploration, maritime patrol, underwater detection, etc. With the continuous progress of technology, the development prospect of water unmanned vehicles is very broad. With the continuous development of global marine economy, the demand for water unmanned vehicles in the fields of marine exploration, port management, maritime traffic control, etc. is increasing.
[0003] In the current stage of marine work, the work dinghy and unmanned vehicle often need to be captured in advance by the "transition floating dock" outside the mother ship. At this time, in order to limit the lateral drift of the equipment in the water, a lateral blocking passage system needs to be set up.
[0004] Water vehicles vary in length and width, and have different draft depths. As an important part of the capture system, the deceleration system needs to have strong adaptability and good compatibility with the equipment, which can effectively improve the capability of the capture system.
[0005] The existing water vehicle capture does not form a specific deceleration passage and does not have the ability to adjust the blocking range and blocking force in sections. The blocking device is fixed and cannot adjust the blocking range and blocking force according to different specifications of the vehicle, which can easily cause damage to the water vehicle. For example, for vehicles with horizontal wings in the middle section, the blocking mechanism near the wings needs to reduce the blocking action range or even not to move in order to avoid collision risks. When recovering a small boat, the width of the bow is smaller than the middle and rear parts, so the mechanisms in different areas need to adapt to different width requirements and make corresponding blocking range. The hulls of some unmanned vehicles have weak pressure capacity, so the blocking mechanism needs to adjust the contact surface of the flexible material and detect the pressure stress to ensure the safety of the hull. SUMMARY
[0006] The present application aims to provide a water vehicle blocking system to solve the technical problem of capturing water vehicles in a limited passage during the recovery process.
[0007] To achieve the above-mentioned purpose, the specific technical solution of a water vehicle blocking system of the present application is as follows:

[0014] In order to realize the adjustment of the blocking direction after the extension of the blocking arm into the water vehicle in the blocking passage, the rotation structure comprises a rotation oil cylinder arranged on the blocking arm support, a rotation connecting block connected with the extension end of the rotation oil cylinder, and a rotation shaft arranged on the extension connecting block; the blocking arm is connected with the rotation connecting block and rotatably connected with the rotation shaft, and the blocking arm rotates under the drive of the rotation oil cylinder.
[0015] In order to avoid damage to the water vehicle when contacting the water vehicle, the material of the outer surface of the load support and the blocking arm is a flexible material.
[0016] In order to realize the extension of the extension arm, the extension connecting block enters the blocking arm support, the blocking arm support is a hollow structure, the extension connecting block is connected with the blocking arm support through a guide rail structure, the guide rail structure is arranged in the blocking arm support, and the extension connecting block is retracted into the blocking arm support when the extension oil cylinder is retracted.
[0017] In order to realize the constraint of the water vehicle after the extension of the blocking arm into the blocking passage, constrain the vehicle on both sides at the same time, adjust the direction of the vehicle's advance, and avoid the deviation of the vehicle, the blocking device is symmetrically distributed on the corresponding load support.
[0018] In order to realize the buffering and fixing of the vehicle after entering the capture area, the blocking support of the capture area is provided with a buffering structure and a fixing structure.
[0019] In order to adapt to the blocking requirements of different sections of the water vehicle and control the amplitude of the blocking action, an angle encoder is arranged on the rotating shaft, a displacement sensor is arranged on the telescopic oil cylinder, and the control device controls the telescopic degree and rotating angle of the blocking arm according to the feedback signals of the angle encoder and the displacement sensor.
[0020] In order to prevent the side wall of the water vehicle from being damaged due to excessive pressure, a pressure sensor is arranged on the rotating oil cylinder, and the control device controls the telescopic degree and rotating angle of the blocking arm according to the feedback signal of the pressure sensor.
[0021] Beneficial effects:
[0022] By arranging the blocking channel, the lateral drift of the water vehicle is avoided, the blocking device is arranged to extend the blocking arm into the blocking channel to constrain the advancing direction of the water vehicle, and after the gradual constraint of multiple blocking arms, the water vehicle completes the speed reduction and stopping in the capture area. By arranging the control device to drive and adjust the telescopic and rotating of the blocking arm, different specifications and different entering speeds of the water vehicle are adapted.

At the end of the arresting channel 120 along the direction of the vehicle's movement is a capture area 121. The vehicle decelerates after passing through the arresting channel 120 and stops in the capture area 121. The arresting supports in the capture area 121 are equipped with a buffer structure and a fixing structure to achieve buffering and fixing of the vehicle after it enters the capture area.

The telescopic connecting block 232 is connected to the barrier arm bracket 220 through a guide rail structure, which is set inside the barrier arm bracket 220. When the telescopic cylinder 231 retracts, the telescopic connecting block 232 retracts into the barrier arm bracket 220. The rotating structure 240 includes a rotating cylinder 241 set on the barrier arm bracket 220, a rotating connecting block 242 connected to the telescopic end of the rotating cylinder 241, and a rotating shaft 243 set on the telescopic connecting block 232. Figure 4 As shown, the blocking arm 210 is connected to the rotating connecting block 242 and rotatably connected to the rotating shaft 243, and rotates under the drive of the rotating cylinder 241.

[0038] Through the angle encoder arranged on the rotating shaft 243 and the displacement sensor feedback of the extension cylinder 231, the amplitude control of the blocking action can be realized, so as to adapt to the blocking requirements of different sections of water vehicles.
[0039] Through the pressure sensor installed on the rotating cylinder 241, the blocking action can be suspended in time through pressure value feedback to prevent the side wall of the water vehicle from being damaged due to excessive pressure.
