[0018] S1, ensure that the cleaning mechanism is disengaged from the paint roller;

[0019] S2: The staff manually adjusts the roller adjustment assembly to move the paint roller downward until it contacts the ship's surface to be painted. During the downward movement of the paint roller, the first support rod securing the paint roller moves downward synchronously with the first pulley. The first pulley pulls the tensioning belt, thereby squeezing the second pulley downward to cause the sliding rod to move downward synchronously.

[0020] Then, a specific amount of paint is added to the paint box, and the staff pulls the entire ship painting construction device to move it on the ship's board to be painted. The paint in the paint box slides down from the leakage hole in the center of the receiving plate, the strip hollow plate, the strip slide plate and the strip hole in the center of the painting arc plate onto the paint roller in turn. When the paint roller rolls, the strip brushes on both sides of the painting arc plate evenly apply the paint to the outer surface of the paint roller, thus painting the ship's board to be painted.

[0021] As the paint roller rolls, the first support rod that fixes the paint roller rotates in the circumferential direction. The first support rod drives the second support rod to rotate through the pulley assemblies at both ends of the first support rod, thereby driving the fan blades to rotate, blowing air to the paint to dry the applied paint.

[0022] S3, after the painting operation is completed, the staff manually adjusts the roller adjustment assembly so that the paint roller (206) moves upward to the initial position, at which time the front surface of the friction wheel contacts the rear surface of the paint roller;

[0023] S4, the staff manually pushes the cleaning mechanism to make its cleaning plate contact with the paint roller, then starts the water pump and the motor, uses the motor to drive the friction wheel to rotate, and the friction between the friction wheel and the paint roller causes the paint roller to rotate. The water pump pumps the water in the water tank through the delivery pipe to the water inlet of the cleaning plate to clean the paint on the outer surface of the paint roller.

[0024] The beneficial effects of the present invention are:

[0025] 1. The device of the present invention utilizes a coating mechanism to drive the air-drying mechanism to operate when painting the shipboard, so as to blow dry the paint painted on the surface of the shipboard, thereby air-drying the coating layer and improving the air-drying efficiency of the paint layer; at the same time, the strip brushes on both sides of the curved plate can evenly apply the paint on the outer surface of the paint roller to achieve uniform paint painting, making the painting operation convenient and quick, and making the coating thickness more uniform; after the painting operation is completed, the cleaning mechanism can comprehensively clean the surface of the paint roller, thereby improving work efficiency and reducing labor costs.

[0026] 2. The air-drying mechanism blows air to the painted area during the painting operation to accelerate the drying of the paint and reduce the possibility of dust contamination before the paint layer dries. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention provides a ship painting construction device, which is characterized by comprising a shell 1, a painting mechanism 2, an air-drying mechanism 3 and a cleaning mechanism 4 arranged on the shell 1.

[0046] The coating mechanism 2 is used for coating the ship panels to be coated. It is arranged inside the shell 1 and its two ends extend from both sides of the shell 1 and can be manually adjusted to move up and down in the shell 1.

[0047] The coating mechanism 2 includes a paint box 214 arranged inside the shell 1, a paint delivery assembly arranged at the bottom of the paint box 214, a painting arc plate 207 arranged at the bottom of the paint delivery assembly, and a roller adjustment assembly that can move downward in the shell 1 and can move upward and reset under the action of the air-drying mechanism 3.

[0048] The paint delivery assembly is used to deliver the paint in the paint box 214 to the painting arc plate 207, and apply the paint to the paint roller 206 of the roller adjustment assembly under the action of the painting arc plate 207 to achieve uniform painting of the paint.

[0049] The paint conveying assembly includes a strip hollow plate 210 and a first telescopic rod 211 fixed at the bottom of the paint box 214, a strip slide 209 arranged in the strip hollow plate 210 and connected to the upper end surface of the painting arc plate 207, and a connecting plate 212 fixed on both sides of the strip slide 209. The first telescopic rod 211 is arranged on both sides of the strip hollow plate 210 and its lower end is fixed on the corresponding connecting plate 212. A return spring 215 is provided on the first telescopic rod 211. One end of the return spring 215 is fixed to the bottom of the paint box 214 and the other end is fixed to the connecting plate 212. The strip slide 209 is an internal hollow structure.

[0050] The coating box 214 is composed of a rectangular box body and a material receiving plate 213 fixed to the bottom of the rectangular box body. The center of the material receiving plate 213 is provided with a material leakage hole aligned with the strip hollow plate 210.

[0051] A plurality of strip brushes 208 arranged at equal intervals are provided on both sides of the painting arc plate 207 , and a strip hole is opened in the middle of the painting arc plate 207 and is aligned with the inner hollow chamber of the strip slide 209 .

[0052] When paint is added to the paint box 214, the paint will flow into the strip hollow plate 210 from the leakage hole in the center of the receiving plate 213, and then flow into the strip hole in the middle of the painting arc plate 207 through the inner hollow chamber inside the strip slide 209, and slide from the strip hole to the paint roller 206.

[0053] When the roller adjustment assembly is in the initial position, the paint roller 206 squeezes the paint arc plate 207 so that the paint conveying assembly is in a compressed state, that is, the paint roller 206 squeezes the paint arc plate 207 so that the strip slide 209 is retracted in the strip hollow plate 210, and the return spring 215 is in a compressed state. When the roller adjustment assembly is manually adjusted to make the paint roller 206 move downward inside the shell 1, the strip slide 209 and the painting arc plate 207 will also move downward under the action of the elastic force of the return spring 215. When the paint roller 206 moves downward until it contacts the surface of the ship to be painted, the distance between the painting arc plate 207 and the paint roller 206 is half the length of the strip brush 208. At this time, the return spring 215 is still in a slightly compressed state or in a free state without deformation. In this way, when the paint roller 206 rolls, the paint that slides onto the paint roller 206 can be evenly applied to the outer surface of the paint roller 206 under the action of the strip brushes 208 on both sides of the painting arc plate 207.

[0054] Sliding grooves 205 are provided at the lower parts of both sides of the housing 1 , and the two ends of the roller adjustment assembly extend out of the housing 1 from the corresponding sliding grooves 205 .

[0055] The roller adjustment assembly includes a first support rod 204 which is horizontally arranged in the shell 1 and whose two ends extend from the sliding grooves 205 at the lower parts of both sides of the shell 1, a paint roller 206 which is sleeved on the first support rod 204, a fixed horizontal plate 202 which is horizontally fixed on the outer surface of the shell above the sliding groove 205, and a threaded rod 201 with a vertical thread embedded through the fixed horizontal plate 202. A first connecting sleeve 203 is fixed to the lower end of the threaded rod 201, and the first connecting sleeve 203 is sleeved on the corresponding end of the first support rod 204. The two ends of the first support rod 204 are respectively connected to the air-drying mechanism 3 through a group of pulley assemblies.

[0056] When the threaded rod 201 is manually screwed, the threaded rod 201 drives the first support rod 204 to move in the vertical direction (ie, up and down), thereby moving the paint roller 206.

[0057] Since the two ends of the roller adjustment assembly and the air-drying mechanism 3 are respectively connected by a set of pulley assemblies, that is, when the paint roller 206 moves downward to contact the surface of the ship to be painted and rolls, the first support rod 204 that fixes the paint roller 206 will rotate, and the first support rod 204 will transmit power to the air-drying mechanism 3 through the pulley assembly.

[0058] Sliding holes 308 are provided at the lower parts of both sides of the shell, and the two ends of the air-drying mechanism 3 extend out of the shell 1 from the corresponding sliding holes 308 respectively.

[0059] The air-drying mechanism includes a second support rod 311, parallel to the first support rod 204, disposed on one side of the first support rod 204; a sliding rod 304 disposed between the first support rod 204 and the second support rod 311; and a fan blade 312 sleeved on the second support rod 311. The second support rod 311 has two ends extending from either side of the housing, with third connecting sleeves 313 fixed to its protruding sections. The third connecting sleeves 313 are secured to second support plates 315 horizontally secured to either side of the housing via fixing rods 314. The sliding rod 304 has two ends extending from sliding holes 308 on either side of the housing, with second connecting sleeves 305 fixed to its protruding sections. The second connecting sleeves 305 are secured to first support plates 309 horizontally secured to either side of the housing via second telescopic rods 307. A support spring 306 is disposed on the second telescopic rod 307, with one end of the support spring 306 secured to the second connecting sleeve 305 and the other end secured to the first support plate 309.

[0060] A set of pulley assemblies are respectively provided at both ends of the first support rod 204, the second support rod 311 and the sliding rod 304 to realize the transmission connection between the air-drying mechanism and the drum adjustment assembly. Figure 5 As shown, Figure 5 Only one set of pulley assemblies is drawn, and the other set of pulley assemblies is not drawn.

[0061] The pulley assembly includes a first pulley 301 fixed at the end of the first support rod, a second pulley 303 fixed at the end of the sliding rod 304, and a third pulley 310 fixed at the end of the second support rod 311. A belt 302 is wound around the first pulley 301, the second pulley 303 and the third pulley 310.

[0062] As the paint roller 206 moves downward, the first support rod 204 securing the paint roller 206 moves downward synchronously with the first pulley 301. The downward movement of the first pulley 301 pulls the tensioning belt 302, thereby squeezing the second pulley 303 downward to cause the sliding rod 304 to move downward synchronously, and the sliding rod 304 moves downward along the sliding hole 308. When the paint roller 206 moves downward until it contacts the surface of the ship to be painted and rolls, the first support rod 204 rotates. The first support rod 204 transmits power to the second support rod 311 via the first pulley 301, the second pulley 303, the third pulley 310, and the belt 302, driving the second support rod 311 to rotate, thereby rotating the fan blades 217, blowing air onto the paint applied on the surface of the ship to be painted to dry the paint.

[0063] A portion of the cleaning mechanism 4 is located outside the housing 1 , and another portion is located inside the housing 1 , and the cleaning mechanism 4 can be brought into contact with or out of contact with the paint roller 206 under the action of a push or pull force.

[0064] The cleaning mechanism includes a motor 401 fixed to the side of the shell 1, a water tank 402 fixed to the top surface of the shell 1, a cleaning plate 409 arranged inside the shell 1 and located on one side of the paint roller 206, a connecting plate 406 connected to the cleaning plate 409 through a buffer spring 413, two connecting rods 407 fixed on the connecting plate 406 and extending from the side of the shell where the motor 401 is fixed, and a fixed connecting rod 411 connecting the two connecting rods 407, a rotating rod 410 is installed at the output end of the motor 401, and a friction wheel 405 is fixed to the end of the rotating rod 410, the front surface of the friction wheel 405 is in contact with the rear surface of the paint roller 206, a water pump 403 is connected to the water tank 402, and the water outlet of the water pump 403 is connected to the water inlet of the cleaning plate 409 through a delivery pipe.

[0065] The delivery pipeline includes an L-shaped pipeline 404 connected to the water outlet of the water pump 403, and a folded pipeline 408 connected to the L-shaped pipeline 404 and the water inlet of the cleaning plate 409;

[0066] The outer side of the housing 1 is further provided with a support seat 412 , through which the connecting rod 407 passes and can be locked and fixed to the support seat 412 by bolts.

[0067] The present invention also provides a method for using the ship coating construction device, which specifically includes the following steps:

[0068] S1, ensure that the cleaning mechanism 4 is in a disengaged state from the paint roller 206. If the cleaning mechanism 4 is not in a disengaged state from the paint roller 206 but is in contact with the paint roller 206, the staff holds the fixed connecting rod 411 and pulls the cleaning mechanism 4 outward to disengage the cleaning plate 409 from the paint roller 206, and then passes the bolt through the connecting rod 407 and the support seat 412, and locks the connecting rod 407 and the support seat 412 to lock the cleaning mechanism 4 in this state.

[0069] S2, the staff manually adjusts the roller adjustment assembly so that the paint roller 206 moves downward until it contacts the ship's surface to be painted, that is, manually screws the threaded rod 201 so that the paint roller 206 moves downward until it contacts the ship's surface to be painted;

[0070] During the downward movement of the paint roller 206, the first support rod 204 fixing the paint roller 206 moves downward synchronously with the first pulley 301, and the first pulley 301 pulls the tensioning belt 302 to press the second pulley 303 downward to make the sliding rod 304 move downward synchronously;

[0071] Then, a specific amount of paint is added to the paint box 214. The paint in the paint box 214 slides down from the leakage hole in the center of the receiving plate 213, the strip hollow plate 210, the strip slide plate 209 and the strip hole in the center of the painting curved plate 207 onto the paint roller 206. The staff pulls the entire ship painting construction device to move it on the ship board to be painted. When the paint roller 206 rolls, the paint is evenly applied to the outer surface of the paint roller 206 under the action of the strip brushes 208 on both sides of the painting curved plate 207, thereby painting the ship board to be painted.

[0072] While the paint roller 206 is rolling, the first support rod 204 is rotating in the circumferential direction. The first support rod 204 transmits power to the second support rod 311 through the first pulley 301, the second pulley 303, the third pulley 310 and the belt 302, driving the second support rod 311 to rotate, thereby driving the fan blades 217 to rotate, blowing air on the paint to dry the painted paint.

[0073] S3, after the painting operation is completed, the worker reversely rotates the threaded rod 201 to move the paint roller 206 upward to the initial position. At this time, the front surface of the friction wheel 405 contacts the rear surface of the paint roller 206.

[0074] S4, the staff manually pushes the cleaning mechanism 4 so that the cleaning plate 409 contacts the paint roller 206, that is, removes the bolts fixing the connecting rod 407 and the support seat 412, and pushes the fixing connecting rod 411 inward to make the cleaning plate 409 contact the paint roller 206;

[0075] Then, start the water pump 403 and the motor 401, and use the motor 401 to drive the friction wheel 405 to rotate. The friction between the friction wheel 405 and the paint roller 206 causes the paint roller 206 to rotate. The water pump 403 pumps the water in the water tank 402 through the delivery pipe to the water inlet of the cleaning plate 409 to clean the paint on the outer surface of the paint roller 206.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
