[0024] As Figures 1 to 4 shown, the multifunctional spraying ship includes a ship body 1. The ship body 1 includes a paddle wheel engine body 4 and a cabin. The paddle wheel engine body 4 is installed at the rear side of the ship body 1. A groove is formed at the bottom of the inner wall of the cabin. A diesel generator 6 is arranged inside the groove. A spraying mechanism 3 for cleaning the river surface is placed inside the groove. A protection mechanism 5 is arranged at the bottom of the inner wall of the cabin. A salvage mechanism 2 is installed at the front side of the ship body 1. An electrical connection is made between the output end of the diesel generator 6 and the access end of the spraying mechanism 3. Specifically, by starting the spraying mechanism 3, the medicament is sprayed onto the river surface, thereby completing the cleaning of blue-green algae and harmful bacteria on the river surface. The diesel generator 6 transmits current to the spraying mechanism 3, so that subsequent workers do not need to install a generator or a driving mechanism during the process of controlling the spraying mechanism 3 to spray the medicament, and the mass of the subsequent ship body 1 during use is reduced, thereby minimizing the problems of high energy consumption, low efficiency, and easy failure during the subsequent use of the ship. Therefore, the practicability of the device is improved.

[0025] like Figures 1 to 3 As shown, the spraying mechanism 3 includes a medicine box 304, a water pump 1 306, a mixing box 308, a water pump 2 310 and an electric control box 303. The medicine box 304, the water pump 1 306, the mixing box 308 and the water pump 2 310 are installed at the bottom of the inner wall of the groove of the ship body 1, and the electric control box 303 is installed on the upper surface of the ship body 1. The drainage end of the medicine box 304 is provided with a connecting pipe 1 305, and the drainage end of the connecting pipe 1 305 is installed at the water inlet hole of the water pump 1 306. The drainage end of the water pump 1 306 is connected to a connecting pipe 2 307, and the outer surface of the connecting pipe 2 307 is provided with a metering pump 315. The drainage end of the connecting pipe 2 307 is installed inside the water inlet of the mixing box 308. The top of the mixing box 308 is provided with a motor 312, and the output shaft of the motor 312 passes through the top of the mixing box 308. A rotating rod 313 is installed at the end, and multiple groups of stirring rods 314 are arranged on the outer surface of the rotating rod 313. A connecting pipe three 309 is arranged at the drainage end of the mixing box 308, and the drainage end of the connecting pipe three 309 is installed inside the water inlet hole of the water pump two 310. A connecting pipe four 311 is arranged at the drainage end of the water pump two 310. A through hole is opened on the side of the groove of the ship body 1 close to the propeller body 4. The connecting pipe four 311 passes through the through hole inside the ship body 1 and is installed with a fixed pipe 301. Multiple groups of nozzles 302 are arranged on the lower surface of the fixed pipe 301. The output end of the diesel generator 6 and the access end of the electric control box 303 are electrically connected, and the electric control box 303 and the control end of the water pump one 306, the metering pump 315, the motor 312, the water pump two 310 and the propeller body 4 are electrically connected.

[0026] Specifically, when the subsequent ship body 1 is traveling in the river, the propeller body 4, the water pump 1 306 and the water pump 2 310 are started by controlling the electric control box 303, and the medicine accumulated in the medicine box 304 is transported to the inside of the fixed pipe 301 along the multiple sets of pipes, and then the medicine is sprayed to the river surface through the multiple sets of nozzles 302, so as to complete the cleaning of blue algae and harmful bacteria on the river surface; the diesel generator 6 transmits electric current to the electric control box 303 to start the propeller body 4, so that the subsequent staff does not need to install a generator or drive the spray mechanism 3 to spray the medicine. The driving mechanism reduces the quality of the subsequent ship body 1 during use, thereby avoiding the problems of high energy consumption, low efficiency and easy failure during the subsequent use of the ship, thereby improving the practicality of the device; when the subsequent agent enters the interior of the mixing box 308, the motor 312 is started by controlling the electrical control box 303 to drive the rotating rod 313 and the stirring rod 314 to stir the agent and water accumulated in the mixing box 308, so that the agent and the water can be fully mixed, thereby improving the disinfection effect of the subsequent spraying mechanism 3 spraying the medicine.

[0027] In addition, when the subsequent staff starts the spraying mechanism 3 to spray the medicament while operating the electric control box 303, the metering pump 315 is synchronously turned on. The metering pump 315 records the amount of the medicament guided from the medicament tank 304 into the mixing tank 308, so that the subsequent spraying mechanism 3 can accurately measure the spraying during use, thereby minimizing the situation where the subsequent spraying mechanism 3 sprays out an excessive amount of medicament, which may cause the death of cyanobacteria and harmful bacteria in the river while also making it impossible for fish in the water to survive. Therefore, the safety and stability of the subsequent spraying mechanism 3 during use are improved.

[0028] As Figure 1 , Figure 2 and Figure 4 shown, the protection mechanism 5 includes a protection cover plate 501 and a hinge 504. The bottom of the inner wall of the ship's cabin is hinged with a protection cover plate 501 through the hinge 504. A clamping block 503 is arranged on the lower surface of the protection cover plate 501. A clamping groove is opened at the bottom of the inner wall of the ship's cabin, and the position of the clamping groove is on the rotation path of the clamping block 503. The position of the groove of the ship body 1 is directly below the rotation path of the protection cover plate 501;

[0029] Specifically, when the subsequent staff drives the device, by pushing the protection cover plate 501, the clamping block 503 is clamped inside the clamping groove of the ship body 1, so that the protection cover plate 501 is positioned and installed at the upper end of the bottom of the inner wall of the ship's cabin. Then, due to the position of the groove of the ship body 1 being directly below the rotation path of the protection cover plate 501, the protection cover plate 501 shields and protects the inside of the groove of the ship body 1, thereby minimizing the situation where the subsequent diesel generator 6 gets rained on or is damaged after coming into contact with the river water. Therefore, the service life of the diesel generator 6 is extended, and at the same time, the noise is reduced and the working environment is improved.

[0030] As Figure 1 and Figure 2 shown, the fishing mechanism 2 includes a U-shaped fixing plate 201, three groups of screw rods 202 and a connecting plate 203. The three groups of screw rods 202 are all arranged on the upper surface of the ship body 1. The connecting plate 203 is sleeved on the outer surface of the three groups of screw rods 202. The U-shaped fixing plate 201 is installed on the lower surface of the connecting plate 203. External threads of the three groups of screw rods 202 are all connected with nuts 204. The lower surfaces of the three groups of nuts 204 are all abutted against the upper surface of the connecting plate 203. The back of the U-shaped fixing plate 201 is abutted against the front side of the ship body 1. V-shaped connecting plates 205 are arranged on the inner walls on the left and right sides of the U-shaped fixing plate 201;

[0031] Specifically, when the subsequent ship body 1 is drifting in the river, the position of the ship body 1 is swung to align the gap between the two groups of V-shaped connecting plates 205 with the garbage floating in the river, so that during the drifting of the subsequent ship body 1, the garbage floats along the gap between the two groups of V-shaped connecting plates 205 into the space between the two groups of V-shaped connecting plates 205 and the U-shaped fixing plate 201. Then, under the impact of the river water, the garbage drifting into the space between the U-shaped fixing plate 201 and the two groups of V-shaped connecting plates 205 is not easy to float out of the inside of the salvage mechanism 2, thereby completing the cleaning of the river garbage, so that it is convenient for the subsequent staff to use the salvage mechanism 2 to effectively clean the garbage in the river; the connecting plate 203 is sleeved on the outer surface of the three groups of screws 202, so that the subsequent staff can remove the U-shaped fixing plate 201 from the front side of the ship body 1 by disassembling and moving the three groups of nuts 204, and then by pulling the connecting plate 203, so as to avoid the subsequent salvage mechanism 2 affecting the normal navigation of the ship body 1 in the river during the idle process.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a sealing gasket (502) is provided on the lower surface of the protective cover plate (501), and the lower surface of the sealing gasket (502) abuts against the bottom of the inner wall of the cabin; specifically, the sealing gasket 502 is arranged on the lower surface of the protective cover plate 501 so that the sealing gasket 502 seals the connection between the protective cover plate 501 and the bottom of the inner wall of the cabin, thereby preventing the water flow accumulated in the cabin from penetrating into the groove of the ship body 1 and contacting the diesel generator 6.

[0033] In summary: by controlling the electrical control box 303 to start the propeller body 4, water pump 1 306 and water pump 2 310, the medicine accumulated in the medicine box 304 is transported along multiple sets of pipes to the inside of the fixed pipe 301, and then the medicine is sprayed onto the river surface through multiple sets of nozzles 302, thereby completing the cleaning of blue algae and harmful bacteria on the river surface; by controlling the electrical control box 303 to start the motor 312 to drive the rotating rod 313 and the stirring rod 314 to stir the medicine and water accumulated in the mixing box 308, so that the medicine and the water can be fully mixed, thereby improving the disinfection effect of the subsequent spraying mechanism 3 spraying the medicine.

[0034] At the same time, the metering pump 315 records the amount of medicine guided from the medicine box 304 to the mixing box 308, so that the subsequent spraying mechanism 3 can accurately measure and spray during use, thereby avoiding as much as possible the subsequent spraying mechanism 3 spraying too high a content of medicine, which will cause the death of blue algae and harmful bacteria in the river channel, and the fish in the water will also be unable to survive; by pushing the protective cover 501, the block 503 is clamped in the slot of the ship body 1, so that the protective cover 501 is positioned and installed at the upper end of the bottom of the inner wall of the cabin, and then the position of the groove of the ship body 1 is located at the lower end of the rotation path of the protective cover 501, so that the protective cover 501 blocks and protects the inside of the groove of the ship body 1, thereby avoiding as much as possible the subsequent diesel generator 6 from being damaged by rain or the diesel generator 6 coming into contact with river water.

[0035] In addition, by swinging the position of the ship body 1, the gap between the two groups of V-shaped connecting plates 205 is aligned with the garbage floating in the river, so that during the subsequent drifting of the ship body 1, the garbage floats along the gap between the two groups of V-shaped connecting plates 205 into the space between the two groups of V-shaped connecting plates 205 and the U-shaped fixing plate 201. Under the impact of the river water, the garbage drifting into the space between the U-shaped fixing plate 201 and the two groups of V-shaped connecting plates 205 is not easy to float out of the interior of the salvage mechanism 2, thereby completing the cleaning of the river garbage.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
