[0014] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0015] A forced stopping device for a ship as shown in the figure is arranged on a waterway line, and comprises a plurality of forced stopping units 1 arranged on the water, wherein the forced stopping unit 1 comprises a positioning rod 11, a floating plate 12, a pontoon 13, a power supply 14, a high-frequency microwave transmitting circuit 15, a waveguide antenna 16, a sleeve 17 and a rotating motor 18, wherein the positioning rod is vertically fixed and plugged into the riverbed, and the upper end of the positioning rod is higher than the water surface; the floating plate is fixed to the upper end of the pontoon, and the middle parts of the floating plate and the pontoon are provided with circular holes and are sleeved on the positioning rod through the circular holes; the power supply 14, the high-frequency microwave transmitting circuit 15 and the waveguide antenna 16 are sequentially connected and arranged on the side surface of the floating plate, and the buoyancy generated by the floating plate on the pontoon It floats on the corresponding water surface above the positioning rod; a plurality of guide bars 111 are longitudinally arranged on the upper part of the positioning rod 11, and a plurality of guide grooves are arranged on the inner wall of the sleeve. The sleeve is sleeved on the upper part of the positioning rod and the guide bars are located in the guide grooves, so that the sleeve can move longitudinally on the positioning rod and will not rotate relative to the positioning rod; a magnet is arranged on the lower end of the sleeve, so that it can be attracted to the iron plate fixed in the center of the floating plate but can rotate relatively; a transmission tooth 19 is longitudinally arranged on the outer wall of the sleeve, and the rotating motor 18 is arranged on the floating plate, and the output shaft of the rotating motor is connected to a gear meshing with the transmission tooth. When the rotating motor is operating, the floating plate rotates relative to the positioning rod.

[0016] like Figure 1 , Figure 2 As shown, a plurality of forced stop units are arranged on the water surface by using a buoyancy box and a positioning rod. The radiation ranges of the forced stop units intersect, thereby continuously interfering with the control circuit of the ship entering the radiation range, forcing the ship to stop. The positioning rod is the position center of the floating plate. Combined with the sleeve and the rotating motor, the positioning rod can also become the rotation center of the floating plate, that is, the rotation center of the waveguide antenna. There is no need to set a separate rotation drive mechanism on the basis of fixing the floating plate to adjust the radiation direction of the waveguide antenna.

[0017] The buoyancy box 13 has a cavity inside, and a water volume regulating mechanism 2 is provided on the floating plate. The water volume regulating mechanism is connected to the inside of the buoyancy box and is used to pump water outward or add water into the buoyancy box.

[0018] The water volume regulating mechanism includes a water pump 21, a first pipeline 22, a second pipeline 23, a first bypass pipe 24, a second bypass pipe 25 and four electric valves 26; the first pipeline connects the interior of the float box with the water inlet of the water pump, the second pipeline connects the water outlet of the water pump with the water surface, the first bypass pipe bypasses the first pipeline and the second pipeline; the second bypass pipe also bypasses the first pipeline and the second pipeline; an electric valve is respectively arranged in the first pipeline and the second pipeline; an electric valve is also arranged in the first pipeline between its bypass connection points with the first bypass pipe and the second bypass pipe; an electric valve is also arranged in the second pipeline between its bypass connection points with the first bypass pipe and the second bypass pipe.

[0019] By controlling the four electric valves, the water inlet of the water pump can be connected to the pontoon while the water outlet is connected to the external water surface; or the water inlet of the water pump can be connected to the external water surface while the water outlet is connected to the inside of the pontoon; when adding water to the water tank, the water tank sinks and the floating plate sinks accordingly. Of course, at this time, the center of gravity of the entire forced stop unit sinks, so that the irregular impact force caused by water waves between the upper sleeve and the gear of the rotating motor is weakened; when the water in the water tank is pumped out, the entire forced stop unit rises along the positioning rod. When the water tank is larger, the height that can be raised increases accordingly, and when facing an empty ship with a shallow draft, the success rate of interference can be increased; of course, the upper end of the pontoon is connected to the outside through an air pipe to maintain the pressure balance in the water tank. Using a single water pump with pipelines and electric valves can adjust the amount of water in the pontoon, thereby adjusting the height of the floating plate and the waveguide antenna, to a certain extent, to meet the needs of forced stop operations for different types of ships.

[0020] Since the emergency stop unit is set on the waterway, it is impossible to install a large area of ​​solar panels, and the installation of solar panels may also weaken the wind resistance of the emergency stop unit. Therefore, the power supply is connected to the charging device on land via a cable laid on the riverbed.

[0021] The buoy is provided with a camera for monitoring the ship information at close range, and combined with a remote communication module, it is convenient to realize the remote control forced stop operation; after the target ship stops, the relevant law enforcement personnel go on board to enforce the law.
