[0002] Wind turbines are mainly composed of wind rotors, power generation devices, and energy storage devices. A nacelle is usually set outside the core components such as the power generation device and the energy storage device for protection. The wind turbine nacelle is the protective outer shell of the entire unit. Its reliability directly determines the stability and service life of the wind turbine. The nacelle cover of a wind turbine is usually made of glass fiber reinforced plastic. In order to enhance the reliability of the nacelle cover, an anti-corrosion coating or a paint coating is applied to the outer surface of the nacelle cover through a coating device during the production process.

[0003] The nacelle cover coating device used in the prior art still has certain disadvantages, such as: 1. When coating the outer surface of the existing wind turbine nacelle, the coating operation is directly performed by using a mechanical arm robot or manually operating the paint spray gun to move. However, the paint itself is harmful. Directly using an open coating operation can easily cause the paint to splash during the coating process and spread in the construction environment, causing pollution to the working environment and affecting the health of the operators. 2. The structural shape of the existing wind turbine nacelle cover is similar in overall structure according to different design requirements. In order to ensure the aerodynamic performance of the nacelle cover, it is usually streamlined, such as a cylindrical shell and a box-shaped shell. However, when coating the arc chamfer of the streamlined nacelle cover and the box-shaped shell nacelle cover, the splash shield on the existing spray gun is usually a fixed shield, that is, it cannot be automatically adjusted according to the structural shape of the nacelle cover.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-12 The present invention provides a technical solution: a splash-proof cabin cover outer surface coating machine capable of automatic positioning, comprising a casing frame 1, an adaptive self-adjusting mechanism 3 and a control mechanism 5.

[0020] When the splash-proof cabin cover outer surface coating machine capable of automatic positioning is in use, the adaptive self-adjusting mechanism 3 is arranged on the lower side of the casing frame 1 in a vertical downward state, and is symmetrically arranged front and back about the vertical center axis of the casing frame 1. The control mechanism 5 is arranged directly above the adaptive self-adjusting mechanism 3. The front and rear control mechanisms 5 are respectively fixed on the front and rear side frames of the casing frame 1 after being arranged. According to the structural shape of the cabin cover, the adaptive self-adjusting mechanism 3 is automatically adjusted by the control mechanism 5, and the side edges of the front and rear cover walls of the silicone cover 4 are adaptively adjusted in curvature. After adjustment, the control mechanism 5 is used to automatically position and lock it, and then the adjusted silicone cover 4 is set to block the coating position of the cabin cover to prevent splashing during coating, and the coating operation is performed through the coating nozzle 2; When operating the automatic adjustment of the adaptive self-adjusting mechanism 3, specifically, according to the attached Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, after the servo motor 20 is installed, it is fixed to the shell wall of the shell member 14 by bolts and is arranged horizontally. It is connected to an external power source through wires. Since the output end of the servo motor 20 is inserted into the groove cavity of the shell wall of the shell member 14 after the installation, it is fixedly clamped with the left end of the screw rod 19. Since a wedge-shaped slide groove is provided on the shell cavity wall of the shell member 14, the left and right ends of the screw rod 19 are fixedly clamped with bearings. After the installation, it is placed in the groove cavity of the wedge-shaped slide groove in the shell member 14 and is arranged horizontally. The left and right ends of the screw rod 19 are respectively clamped on the shell walls on both sides of the shell member 14 with bearings. When the servo motor 20 is started to operate, the screw rod 19 is assisted by the bearing to rotate on the shell cavity wall of the shell member 14. Since the lower end of the driving block 17 is provided with a wedge-shaped structure, after being placed, the lower end thereof is movably clamped in the wedge-shaped slide groove in the outer shell 14, and is positioned on the shell cavity wall of the outer shell 14 in an active state. Moreover, since the middle part of the lower end of the driving block 17 is connected with the screw rod 19 in a through manner, and the two are threadedly connected together, the screw rod 19 rotates, driving the driving block 17 to slide on the shell cavity wall of the outer shell 14; Since the upper end of the linkage plate 15 is inclinedly provided with a pressure plate portion of an integrated structure, the driving block 17 is arranged directly below the pressure plate portion in the linkage plate 15, and is connected to the pressure plate portion in the linkage plate 15 by a pressing and fitting manner. In addition, since the left and right sides of the upper end of the driving block 17 are provided with inclined side walls, the driving block 17 is not blocked or restricted when sliding back and forth through the arrangement of the inclined side walls on both sides, that is, the pressure plate portion of the linkage plate 15 can be pushed and squeezed. After the driving block 17 is driven to slide, it contacts the pressure plate portion in the linkage plate 15 with the assistance of the inclined side walls and pushes the squeezing plate portion upwards. Since the upper end of the linkage plate 15 is rotatably connected with a shaft column, it is movably clamped in the shell cavity groove of the shell member 14 after being installed, and the shaft column is fixedly inserted on the shell wall, so that the linkage plate 15 is positioned in the shell cavity of the shell member 14 in an active state, and a rotation structure is formed with the assistance of the shaft column. Since the shell member 14 is fixedly connected to the frame body of the housing frame 1 by bolts after being installed, and the cover is arranged on the outside of the horizontal tube body in the tube shell assembly 6, and since a torsion spring 16 is installed at the connection between the linkage plate 15 and the shell member 14, the torsion spring 16 is movably sleeved on the shaft column in the linkage plate 15 after being installed, and one end of the torsion spring 16 is clamped on the plate body of the linkage plate 15, and the other end of the torsion spring 16 is clamped on the shell cavity wall of the shell member 14. After the pressure plate portion in the linkage plate 15 is pushed upward, the linkage plate 15 is turned inward in the shell cavity of the shell member 14, and the torsion spring 16 is squeezed and elastically deformed; Since the valve plug column assembly 9 is divided into three parts from the outward direction to the inward direction, namely, the valve head part, the valve stem part and the plug column part, wherein the valve head part is sleeved and fixedly connected to the outward end of the valve stem part by bolts, the two parts are arranged on the same horizontal central axis, and the left and right sides of the valve head part are vertically fixedly connected with pins, and since the left and right side walls of the notch at the lower end of the linkage plate 15 are provided with through-shaped slide grooves, after it is installed, the valve head part in the valve plug column assembly 9 is movably clamped in the notch at the lower end of the linkage plate 15, and the left and right pins of the valve head part in the valve plug column assembly 9 are movably inserted in the left and right slide grooves at the lower end of the linkage plate 15, respectively, and the two parts are connected in a sliding manner. After the linkage plate 15 is turned inward, the valve plug column assembly 9 is pushed to move inward; According to the attached Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the tube shell assembly 6 is composed of a vertical tube body and a transverse tube body, wherein the vertical tube body and the transverse tube body are arranged in a vertical state, and the outward end of the transverse tube body in the tube shell assembly 6 is threadedly fixed with a third end cap for limiting. Since the inward end of the valve stem part in the valve plug column assembly 9 is fixed to the plug column part, it is arranged in an integrated structure, and the two are arranged on the same horizontal central axis, and the longitudinal section of the valve stem part in the valve plug column assembly 9 is arranged in a square structure. After the valve plug column assembly 9 is installed, the plug column part is movably inserted into the tube cavity of the transverse tube body in the tube shell assembly 6, and the valve stem part is movably inserted through the third end cap in the tube shell assembly 6 to extend outward, so that the valve plug column assembly 9 is positioned in the tube cavity of the transverse tube body in the tube shell assembly 6 in an active state, and the valve head is placed outside the transverse tube body in the tube shell assembly 6. When the valve plug column assembly 9 is driven to move inward, the valve plug column assembly 9 shrinks and slides in the tube cavity of the transverse tube body in the tube shell assembly 6. Since a second spring 10 is installed at the connection between the valve head of the valve plug column assembly 9 and the transverse tube body of the tube shell assembly 6, the second spring 10 is movably sleeved on the outward section of the valve stem of the valve plug column assembly 9 after being installed, one end of the second spring 10 presses against the outer cover wall of the third end cover in the tube shell assembly 6, and the other end of the second spring 10 presses against the groove cavity of the valve head of the valve plug column assembly 9. After the valve plug column assembly 9 contracts and slides, the second spring 10 is squeezed and elastically deformed; Since the plug part of the valve plug column assembly 9 is fixedly connected with the first sealing ring, the second sealing ring, the third sealing ring and the fourth sealing ring at equal intervals from the outward direction to the inward direction, the first to the fourth sealing rings in the plug part are all in contact with the tube cavity wall of the horizontal tube body, the spacing between two adjacent sealing rings is the same, and the spacing between two adjacent sealing rings is larger than the diameter of the upper end tube mouth of the vertical tube body in the tube shell assembly 6. Since a straight air supply port is provided in the middle between the first sealing ring and the second sealing ring in the valve plug column assembly 9, and since the air supply channel 12 is provided in the frame wall of the casing frame 1, it is composed of a main flow channel and a secondary flow channel. The diameter of the secondary flow channel is the same as the diameter of the upper end tube mouth of the vertical tube body in the tube shell assembly 6, and the upper end tube mouth of the vertical tube body in the tube shell assembly 6 is connected with the middle tube cavity of the horizontal tube body. The valve plug column assembly 9 is set, and the middle tube cavity of the horizontal tube body in the tube shell assembly 6 is also connected with the secondary flow channel in the air supply channel 12. When the valve plug column assembly 9 is in the initial state, the middle section of the plug column portion corresponds to the connection between the secondary flow channel in the air supply channel 12 and the vertical tube body in the tube shell assembly 6, that is, the connection between the secondary flow channel and the vertical tube body corresponds to between the second sealing ring and the third sealing ring, and the connection is sealed. After the valve plug column assembly 9 shrinks and slides, the connection between the secondary flow channel and the vertical tube body corresponds to between the first sealing ring and the second sealing ring, that is, the connection between the secondary flow channel and the vertical tube body is carried out through the air supply straight-through port in the valve plug column assembly 9, and the main channel in the air supply channel 12 is connected to the air supply equipment through a hose (the above-mentioned air supply equipment is a prior art and is not described in the drawings of the specification), and air is supplied to the vertical tube body in the tube shell assembly 6 through the air supply channel 12; Since the tube shell assembly 6 is fixedly arranged on the frame body of the housing frame 1 in an integrated structural state, the lower end of the vertical tube body in the tube shell assembly 6 is threadedly fixedly connected with a first end cap for limiting, and since the upper end of the piston adjusting rod 7 is a plug head, wherein a sealing rubber ring is fixedly clamped on the plug head, after the piston adjusting rod 7 is installed, the plug head is movably inserted into the tube cavity of the vertical tube body in the tube shell assembly 6, and the sealing rubber ring of the plug head is in contact with the tube cavity wall of the vertical tube body, and the lower end tube body movably penetrates through the first end cap in the tube shell assembly 6 and extends outwards. After the vertical tube body in the tube shell assembly 6 is inflated, the plug head in the piston adjusting rod 7 is pushed, so that the piston adjusting rod 7 slides and extends out in the tube cavity of the vertical tube body in the tube shell assembly 6; Since the first spring 8 is installed at the connection between the piston adjusting rod 7 and the vertical tube body in the tube shell assembly 6, the first spring 8 is movably sleeved on the rod body of the piston adjusting rod 7 after being installed, one end of the first spring 8 is pressed against the groove cavity of the plug head in the piston adjusting rod 7, and the other end of the first spring 8 is pressed against the groove cavity of the first end cover in the tube shell assembly 6. After the piston adjusting rod 7 slides out, the first spring 8 is squeezed and elastically deformed; Since the material property of the silicone cover 4 is flexible and elastic, it can cooperate with the adjustment operation. The lower ends of the cover walls on the front and rear sides of the silicone cover 4 are provided with a connecting seat of an integrated structure. Since the lower end of the piston adjusting rod 7 is plugged and fixedly connected to the connecting seat in the silicone cover 4 by bolts, after the piston adjusting rod 7 slides out, it drives the side of the cover wall of the silicone cover 4 to move and deform. When the driving block 17 loses contact with the pressure plate portion in the linkage plate 15 after continuous sliding, and loses the pushing effect on the pressure plate portion, the elastic deformation of the torsion spring 16 is used to reset, driving the linkage plate 15 to reset and flip in the shell cavity of the outer shell 14, and the elastic deformation of the second spring 10 is used to reset, pulling the valve plug column assembly 9 to reset and slide in the horizontal tube body in the tube shell assembly 6, so that the valve plug column assembly 9 is restored to the initial state, and the plug column portion of the valve plug column assembly 9 is used to seal the connection between the secondary flow channel in the air supply channel 12 and the vertical tube body in the tube shell assembly 6 again, that is, the gas in the vertical tube body in the tube shell assembly 6 is cut off and sealed, and the piston adjustment rod 7 is automatically positioned after adjustment through the elastic support of the first spring 8; According to the attached Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, according to the above, linkage plates 15 are arranged at equal intervals from left to right in the shell cavity of the outer shell member 14, and each linkage plate 15 is arranged corresponding to each valve plug column assembly 9. The spacing dimension between the pressure plate parts of two adjacent linkage plates 15 is greater than the width dimension of the driving block 17. When the driving block 17 slides, each linkage plate 15 is driven in turn, that is, the intermittent control drive of each valve plug column assembly 9 is completed. Since the horizontal tube bodies in the tube shell assembly 6 are arranged at equal intervals from left to right in a horizontal forward state, the secondary flow channels in the air supply channel 12 are arranged at equal intervals on the main flow channel, and each secondary flow channel is arranged corresponding to each horizontal tube body in the tube shell assembly 6, and the vertical tube bodies in the tube shell assembly 6 are arranged at equal intervals from left to right in a fan-shaped downward state, the piston adjustment rods 7 distributed in the fan-shaped manner are extended and adjusted in turn; Since the connecting seats in the silicone cover 4 are arranged at equal intervals on the cover wall, and each of the connecting seats is arranged corresponding to each piston adjusting rod 7, the connecting seats of the cover walls on the front and rear sides of the silicone cover 4 are respectively fixedly connected to the lower ends of the front and rear piston adjusting rods 7 by bolts, and since the left and right sides of the casing frame 1 are inclined downwardly provided with cover plate parts of an integrated structure, wherein the left and right cover plate parts are arranged in an "eight" shape, the adaptive self-adjusting mechanism 3 is arranged between the left and right cover plate parts in the casing frame 1, and the front and rear two adaptive self-adjusting mechanisms 3 and the left and right cover plate parts are combined to surround The silicone cover 4 is wound into a frame-like structure, and after being placed, it is inserted and embedded in the frame formed by the combination of the adaptive self-adjusting mechanism 3 and the casing frame 1. The upper cover wall is fixedly connected to the middle frame of the casing frame 1 by bolts, and the lower ends of the left and right cover walls are respectively fixedly connected to the left and right cover plate parts in the casing frame 1 by bolts, and it is arranged in a detachable structural state. After the piston adjusting rod 7 is extended and adjusted in turn, the side of the cover wall of the silicone cover 4 is adjusted to the arc, which is adapted to the structural shape of the cabin cover. In addition, the coating machine can also freely adjust the side of the cover wall of the silicone cover 4 in real time during use; Since both the front and rear sides of the housing frame 1 are vertically upwardly provided with a connecting frame portion of an integrated structure, it is fixedly arranged on the execution end of the robot mechanical arm through the auxiliary fixing of the connecting frame portion, and after the silicone cover 4 is arranged, the through groove in the middle of the upper cover wall corresponds to the through groove in the middle of the housing frame 1 frame body, and the coating nozzle 2 is inserted into the through groove in the middle of the housing frame 1 frame body after being arranged, and extends into the cover cavity through the through groove in the middle of the upper cover wall of the silicone cover 4, and is arranged in a horizontal state, and is fixedly connected to the middle of the housing frame 1 frame body by bolts, and since the coating nozzle 2 is connected to the paint supply device externally through a hose (the above-mentioned paint supply device is a prior art The coating machine is started by the robot arm to move the coating machine to the coating position of the engine cover, so that the silicone cover 4 is shielded at the coating position, and the coating operation is performed by the coating nozzle 2, and the silicone cover 4 is used to prevent the paint from splashing and spreading. Since the left and right cover plates in the housing frame 1 are fixedly installed with a dust cover 13 by bolts, the opening of the dust cover 13 is set in a downward state, and a dust suction device is connected to the outside through a hose (the above-mentioned dust suction device is a prior art and is not described in the drawings of the specification). During the coating process, the diffused and overflowed paint is sucked and collected by the dust cover 13; When the operating control mechanism 5 unlocks and resets the adaptive self-adjusting mechanism 3, specifically, according to the attached Figure 3 , Figure 6 , Figure 8 , Fig. 9 , Fig.11 and Fig.12As shown, the longitudinal section of the transverse frame body in the "L"-shaped frame 22 is arranged in a "convex"-shaped structure. After installation, the transverse frame body is movably clamped on the shell cavity wall of the outer shell member 14, so that it is positioned in the shell cavity of the outer shell member 14 in an active state. Since the longitudinal frame body in the "L"-shaped frame 22 and the driving block 17 are arranged in a corresponding state, after the driving block 17 completes the driving of all the linkage plates 15, it continues to slide and contact with the longitudinal frame body in the "L"-shaped frame 22, pushing the "L"-shaped frame 22 to slide on the shell cavity wall of the outer shell member 14; Since the pushing parts of the integrated structure are arranged at equal intervals on the horizontal frame body of the "L"-shaped frame 22, wherein the pushing parts are arranged with inclined side walls, after the "L"-shaped frame 22 is installed, the pushing parts thereof are movably inserted into the groove cavity of the unlocking plate 18, and since the pushing parts of the integrated structure are arranged at equal intervals in the groove cavity of the unlocking plate 18, wherein the pushing parts are arranged with inclined side walls, and the inclined side walls of the pushing parts are pressed and fitted against the inclined side walls of the pushing parts in the "L"-shaped frame 22, after the "L"-shaped frame 22 is driven to slide, through the cooperation between the pushing parts on the two, the "L"-shaped frame 22 slides in the groove cavity of the unlocking plate 18, pushing the unlocking plate 18 to move; Since the longitudinal section of the unlocking plate 18 is in a "T"-shaped structure, it is movably clamped on the shell cavity wall of the outer shell member 14 after being installed, and is positioned in the shell cavity of the outer shell member 14 in an active state. In addition, since a fourth spring 21 is installed at the connection between the unlocking plate 18 and the outer shell member 14, the fourth spring 21 is arranged at equal intervals on the transverse plate body of the unlocking plate 18, and is symmetrically arranged about the horizontal middle bearing of the unlocking plate 18, one end of which presses against the transverse plate body in the unlocking plate 18, and the other end presses against the shell cavity wall of the outer shell member 14, the unlocking plate 18 is pushed and slid on the shell cavity wall of the outer shell member 14, so that the fourth spring 21 is squeezed and elastically deformed, wherein the fourth spring 21 assists the unlocking plate 18 to return to slide after restoring the elastic deformation; Since an unlocking plate 18 is arranged just above the pressure plate portion in the linkage plate 15, the length of the unlocking plate 18 is greater than the sum of the distances between the pressure plate portions in the linkage plates 15, wherein the longitudinal plate body is connected to the pressure plate portion in the linkage plate 15 by abutting and fitting manner, after the unlocking plate 18 is driven to slide, it contacts the pressure plate portion in the linkage plate 15 and pushes the compression plate portion downward, so that the linkage plate 15 is turned outward in the shell cavity of the outer shell 14, and the torsion spring 16 is compressed to undergo elastic deformation; Since a third spring 11 is installed at the connection between the plug column part in the valve plug column assembly 9 and the transverse tube body in the tube shell assembly 6, both ends of the third spring 11 are fixedly connected with a positioning ring of an integrated structure. After the third spring 11 is installed, it is movably sleeved on the inward section of the valve stem part in the valve plug column assembly 9, and the positioning ring at one end is fixedly connected to the cover cavity wall of the third end cover in the tube shell assembly 6 by bolts, and the positioning ring at the other end is connected to the plug column part in the valve plug column assembly 9 in a pressing and fitting manner. After the linkage plate 15 is flipped toward the outside, the valve plug column assembly 9 is pulled to move toward the outside, so that the valve plug column assembly 9 extends and slides in the tube cavity of the transverse tube body in the tube shell assembly 6, and the third spring 11 is squeezed to undergo elastic deformation, wherein the third spring 11 assists the valve plug column assembly 9 to return to slide after recovering its elastic deformation; Since an air-release "L"-shaped opening is provided in the middle between the third sealing ring and the fourth sealing ring in the valve plug column assembly 9, after the valve plug column assembly 9 is extended and slid, the connection between the secondary flow channel and the vertical tube body corresponds to between the third sealing ring and the fourth sealing ring, that is, the connection between the secondary flow channel and the vertical tube body is achieved through the air-release "L"-shaped opening in the valve plug column assembly 9. At this time, the valve plug column assembly 9 cuts off the air supply operation of the air supply channel 12. In addition, since the second end cover for blocking is fixedly connected to the inner end of the horizontal tube body in the tube shell assembly 6 with threads, the valve plug column assembly 9 can be used for sealing. Through holes are provided at equal intervals on the second end cover to assist the exhaust operation. The transverse channel of the deflated "L"-shaped port in the valve plug column assembly 9 corresponds to the third end cover in the tube shell assembly 6, so that the gas in the vertical tube body in the tube shell assembly 6 passes through the deflated "L"-shaped port and is discharged through the second end cover. The elastic deformation of the first spring 8 is used to reset, and all the piston adjustment rods 7 are synchronously unlocked and reset. When the piston adjustment rod 7 is readjusted, the air supply is first stopped through the air supply channel 12 to drive the drive block 17 to reset to the initial position when sliding. This is the entire working process of the splash-proof nacelle cover outer surface coating machine capable of automatic positioning.
