[0016] The present invention provides an automatic oil-removing solar unmanned boat, which has the following beneficial effects: (1) In this invention, the operator transmits a signal from the operation mother ship to the control box and issues an operation instruction to the unmanned boat. At the same time, the operator turns on the monitoring camera, and the video data is transmitted back to identify the navigation path and identify the oil pollution on the sea surface. Then, the tail booster pump is started. The booster pump directly sucks seawater from the sea through a suction pipe. After the seawater is pressurized, it is sprayed out from the stern duct to provide forward power. The rudder system is started to adjust the rudder angle to control the navigation path of the unmanned boat. After the monitoring camera identifies the oil pollution on the sea surface, the booster suction pump is started to suck seawater, and the siphon hose on the by-pass fire nozzle siphons the environmental protection oil-removing liquid in the cabin, achieving the effect of spraying and removing oil with the dilution agent.

[0017] (2) In the present invention, after the unmanned boat reaches the pre-designed position of the oil absorbent cotton, in order to anchor the oil absorbent cotton on the sea surface and prevent it from being blown away by the waves, the hydraulic jack in the inclined chute at the rear is started to push the first ballast block out of the chute. The ballast block falls into the sea under its own weight. At the same time, the folding rope of the ballast block pulls the rubber ring on the conical fairlead hole to slide down. The rubber ring binds the oil absorbent cotton, completing the deployment of the initial positioning anchor. The recovery winch is started to recover the oil absorbent cotton. The mechanical claw assists in picking up the ballast block to the deck and cuts the folding rope. The oil on the oil absorbent cotton passes through the oil rinsing ring of the oil absorbent cotton, washes the oil into the oil retaining tank and flows back into the cabin until all the oil absorbent cotton is recovered by the recovery winch. The unmanned boat sails to the side of the operating mother ship and is hoisted onto the operating mother ship. The oil in the cabin of the unmanned boat and the oil absorbent cotton are recovered.

[0018] (3) The invention drives the rotating rod to rotate by rotating the double-headed motor, and the rotating rod drives the scraper to rotate. The scraper scrapes the filter to prevent the filter from being blocked by impurities such as seaweed or plastic bags when the booster suction pump sucks seawater, thereby affecting the pumping effect of the booster suction pump. The environmentally friendly oil removal liquid in the siphon tank is stirred by rotating the stirring plate to ensure that the environmentally friendly oil removal liquid is fully mixed and improve the mixing effect of the environmentally friendly oil removal liquid. The sliding plate moves up and down in the siphon tank to help stir and mix the liquid, which can promote the uniform distribution of different components in the solution and avoid excessively high or low local concentrations. This helps to accelerate the reaction rate, especially when performing chemical reactions, dissolutions or solvent exchanges.

[0019] (4) The invention rotates the stirring plate to push the sliding frame upward, and the upward movement of the sliding frame drives the baffle plate to move upward. The upward movement of the baffle plate will break away from the contact with the liquid storage frame, so that the pH adjuster inside the liquid storage frame will enter the one-way valve from the connecting pipe through the liquid outlet, and then enter the siphon hose through the one-way valve, so that the pH adjuster is mixed with the environmentally friendly oil removal liquid, and the pH value of the sea surface oil removal agent will be adjusted to near neutral, avoiding the harm of over-acidic or over-alkaline components to marine life. The sealing is achieved by overlapping the sealing circular plate and the sealing ring, so that the pH adjuster can only enter in a quantitative manner, to prevent excessive entry resulting in an excessively high pH value, which affects the dilution effect.

Sealing is achieved by the coincidence of the sealing circular plate 2611 and the sealing ring 2610, enabling the pH regulator to enter quantitatively only and preventing excessive entry that may cause too high a pH value and affect the dilution effect.

[0033] A second spring is provided between the sliding frame 262 and the liquid storage frame 261. When the stirring plate 259 disengages from the sliding frame 262, the elastic force of the second spring itself will drive the sliding frame 262 to reset.

The rotation of the scraping plate 254 scrapes the filter net 253 to prevent impurities such as seaweed or plastic bags from blocking the filter net 253 when the booster suction pump 5 sucks seawater, affecting the pumping effect of the booster suction pump 5. At the same time, the rotation of the double-headed motor 251 drives the rotation of the rotating rod 255. The rotation of the rotating rod 255 drives the pulley 256, and the rotation of the pulley 256 drives the rotation of the stirring plate 259. The rotation of the stirring plate 259 stirs the environmental protection oil removal liquid in the siphon chamber to ensure that the environmental protection oil removal liquid is fully mixed, improving the mixing effect of the environmental protection oil removal liquid. At the same time, the rotation of the stirring plate 259 pushes the convex block 2512 downward. The downward movement of the convex block 2512 drives the downward movement of the sliding plate 2511. The up and down movement of the sliding plate 2511 in the siphon chamber helps with the stirring and mixing of the liquid, promotes the uniform distribution of different components in the solution, and avoids too high or too low local concentration. Especially during operations such as chemical reactions, dissolution, or solvent exchange, this helps to accelerate the reaction rate.

[0035] The rotation of the stirring plate 259 drives the sliding frame 262 to move upward. The upward movement of the sliding frame 262 drives the baffle plate 265 to move upward. The upward movement of the baffle plate 265 causes it to disengage from the contact with the liquid storage frame 261, enabling the pH regulator inside the liquid storage frame 261 to enter the one-way valve 268 through the liquid outlet hole 266 and the connecting pipe 267, and then enter the siphon hose 7 through the one-way valve 268. This mixes the pH regulator with the environmental protection degreasing liquid, adjusting the pH value of the sea surface oil stain remover to be close to neutral, avoiding harm to marine organisms caused by overly acidic or alkaline components. At the same time, the upward movement of the baffle plate 265 drives the connecting rod 269 to move upward, and the upward movement of the connecting rod 269 drives the sealing circular plate 2611 to move upward. The upward movement of the sealing circular plate 2611 coincides with the sealing ring 2610, and sealing is achieved through the coincidence of the sealing circular plate 2611 and the sealing ring 2610, enabling the pH regulator to enter only quantitatively and preventing excessive entry from causing too high a pH value and affecting the dilution effect.

The scope of the present invention is defined by the appended claims and their equivalents.
