DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the structural features and effects of the present application, the present application will be described in detail below in conjunction with the drawings and specific examples.

[0024] Please refer to Figures 1-7The waste fan blade cleaning device in an embodiment of the present application has opposite first direction x, second direction y and third direction z, and comprises a shell member 1 which is assembled on the mechanical arm side and movably abuts on the fan blade to be cleaned; a flow guide assembly 2 and a cleaning assembly 3 which are both assembled on the shell member 1, the flow guide assembly 2 has opposite locking state and release state, the cleaning assembly 3 is rotationally arranged on the flow guide assembly 2, the cleaning assembly 3 has opposite cleaning state and spraying state, the locking state and the release state of the flow guide assembly 2 correspond to the cleaning state and the spraying state of the cleaning assembly 3 respectively, the cleaning state of the cleaning assembly 3 is used for cleaning the surface of the fan blade, and the spraying state of the cleaning assembly 3 is used for cleaning the damaged edge part of the fan blade; the shell member 1 comprises a main shell 101, a side groove body 102, a bottom shell 103 and a pump liquid cavity 104, a plurality of side groove bodies 102 are circumferentially arranged on the cylinder wall of the main shell 101, the bottom shell 103 is fixedly assembled at the bottom of the main shell 101, and the pump liquid cavity 104 is further arranged in the main shell 101.

[0025] In actual application, more than 90% of the core reinforcing material of the fan blade is glass fiber and / or carbon fiber. In order to facilitate transportation, the waste fan blade needs to be cut, which causes the composite material to be layered, the bonding interface between the fiber and the resin is damaged, the fiber bundle is directly exposed, the glass fiber at the section position of the blade is directly exposed, dust and oil stains are more easily embedded in the loose fiber bundle, and the exposed glass fiber is brittle. When using conventional mechanical cleaning tools, the residual glass fiber is easily broken, increasing the cleaning difficulty, and the broken glass fiber is scattered everywhere, which not only easily stimulates the skin and respiratory tract of the operator, but also may damage electrical equipment due to the conductivity of the fiber dust. When the device is used to clean the waste fan blade, the shell member 1 is installed on the mechanical arm for cleaning the blade. The mechanical arm uses existing technical means, as long as the fixed distance between the shell member 1 and the blade can be controlled, and details are not repeated here. The shell member 1 comprises a main shell 101, a side groove body 102, a bottom shell 103 and a pump liquid cavity 104. The bottom shell 103 is fixedly assembled at the bottom of the main shell 101. A plurality of side groove bodies 102 are circumferentially arranged on the cylinder wall of the main shell 101. The flow guide assembly 2 is slidingly assembled on the main shell 101 along the arrangement direction of the side groove body 102. The pump liquid cavity 104 is arranged in the main shell 101. The pump liquid cavity 104 is used to connect the input cleaning liquid and guide the cleaning liquid into the flow guide assembly 2 and the cleaning assembly 3. The cleaning assembly 3 is rotatably assembled on the flow guide assembly 2, so that when the shell member 1 approaches the fan blade, the cleaning assembly 3 can continuously clean the surface of the blade during continuous rotation. When the device moves to the edge position of the blade, the cleaning assembly 3 retracts a plurality of cleaning units in it after detecting the edge position of the blade, changes the rotary cleaning mode to jet cleaning mode, and sprays cleaning liquid at an oblique angle to the glass fiber bundle at the section position by using a flat fan-shaped nozzle, thereby ensuring the cleaning effect and avoiding fiber brittle fracture caused by vertical mechanical washing.

[0026] Please refer to Figure 2 , Figure 3 and Figure 5 In a preferred embodiment of the present application, the shell member 1 further comprises an inlet pipe 105, a hose 106, an impeller 107 and a driving bevel gear 108. One side of the pump liquid cavity 104 is connected with the inlet pipe 105. The inlet pipe 105 is arranged along the tangential direction of the pump liquid cavity 104. The other end of the pump liquid cavity 104 is provided with the hose 106. The impeller 107 is rotatably arranged in the pump liquid cavity 104. The driving bevel gear 108 is arranged outside the pump liquid cavity 104 and coaxially fixedly connected with the impeller 107.

[0027] In actual application, the inflow pipe 105 is arranged on one side of the main shell 101 and in the tangential direction of the inner cavity of the pump liquid cavity 104, so that the cleaning liquid pumped into the pump liquid cavity 104 along the inflow pipe 105 acts on the blades of the impeller 107 vertically, thereby driving the impeller 107 to rotate in the xoy plane, and the driving bevel gear 108 is driven to rotate synchronously by the impeller 107, and the position of the driving bevel gear 108 in the third direction z remains unchanged.

[0028] Please refer to Figure 2 and Figure 4 In a preferred embodiment of the present application, the flow guide assembly 2 comprises an inner flow guide bin 201, an outer flow guide bin 202, a communication pipe 203, a sleeve 204 and a guide column 205. The inner flow guide bin 201 is slidingly arranged in the inner cavity of the main shell 101. The outer flow guide bin 202 is arranged outside the main shell 101 and is connected in communication with the inner flow guide bin 201 through the communication pipe 203. The communication pipe 203 is slidingly arranged in the side groove body 102. The sleeve 204 is further fixedly arranged at the bottom of the inner flow guide bin 201. One end of the guide column 205 is elastically inserted into the sleeve 204, and the other end of the guide column 205 is fixedly assembled on the bottom shell 103.

[0029] In actual application, the inner flow guide bin 201 is slidingly arranged in the main shell 101 in the third direction z. The outer flow guide bin 202 is arranged outside the main shell 101 and is connected in communication with the inner flow guide bin 201 through the communication pipe 203. The communication pipe 203 is limitingly arranged in the side groove body 102. The sleeve 204 is fixedly assembled at the bottom of the inner flow guide bin 201. The guide column 205 is elastically slidingly inserted into the bottom of the sleeve 204. The guide column 205 is fixedly arranged on the bottom shell 103, so that the inner flow guide bin 201 is located at the highest point in the third direction z in the non-working condition, and the inner flow guide bin 201 is in the loosened state. When the inner flow guide bin 201 moves in the negative direction of the third direction z under the driving of external force, the inner flow guide bin 201 moves against the elastic force and drives the outer flow guide bin 202 to move synchronously in the negative direction of the third direction z, so that the inner flow guide bin 201 is switched from the loosened state to the locked state. The pump liquid cavity 104 and the inner flow guide bin 201 are connected in communication through the hose 106, so that the inner flow guide bin 201 is always connected in communication with the pump liquid cavity 104 during the movement, and the cleaning liquid is pumped into the outer flow guide bin 202 along the inner flow guide bin 201.

[0030] Please refer to Figure 3 and Figure 6In a preferred embodiment of the present embodiment, the flow guide assembly 2 further comprises a transmission bevel gear 206, a first transmission wheel 207, a second transmission wheel 208, a third transmission wheel 209, and a buckle 210.

The second transmission wheel 208 and the third transmission wheel 209 are coaxially assembled and rotationally arranged on the built-in flow guide bin 201. The transmission bevel gear 206 and the drive bevel gear 108 are in meshing engagement. The first transmission wheel 207 and the second transmission wheel 208 are in meshing engagement. The buckle 210 is fixedly arranged on one side of the sleeve 204.

[0031] In actual application of the present embodiment, the transmission bevel gear 206 and the first transmission wheel 207 are both fixedly arranged on the built-in flow guide bin 201, and the transmission bevel gear 206 and the drive bevel gear 108 are matched arranged. When the built-in flow guide bin 201 is in a loosened state, the transmission bevel gear 206 and the drive bevel gear 108 are arranged at intervals. When the built-in flow guide bin 201 is in a locked state, the transmission bevel gear 206 and the drive bevel gear 108 are in meshing engagement, and then the first transmission wheel 207 drives the second transmission wheel 208 to rotate, thereby synchronously driving the third transmission wheel 209 to rotate. When the built-in flow guide bin 201 is in a loosened state, the third transmission wheel 209 stops rotating.

[0032] Please refer to Figure 3 , Figure 5 and Figure 7 In a preferred embodiment of the present application, the cleaning assembly 3 comprises a rotary disc 301, an inner tooth ring 302, a jet cylinder 303, a valve column 304, an inner through pipe 305, a connecting column 306, a bottom spray port 307, a cleaning brush 308, and a side connecting rod 309. The rotary disc 301 is rotationally assembled on the outer flow guide bin 202, and the inner cavity of the rotary disc 301 and the inner cavity of the outer flow guide bin 202 are in communication. The inner diameter end of the rotary disc 301 is provided with the inner tooth ring 302. The inner tooth ring 302 and the third transmission wheel 209 are in meshing engagement. The valve column 304 is slidably arranged inside the jet cylinder 303. The inner through pipe 305 is arranged inside the valve column 304. One end of the connecting column 306 is slidably inserted into the jet cylinder 303, and the other end of the connecting column 306 is fixedly connected to the valve column 304. The cavity bottom of the jet cylinder 303 is further provided with a plurality of bottom spray ports 307. The cleaning brush 308 is fixedly assembled at the bottom of the connecting column 306. One end of the cleaning brush 308 is further fixedly assembled with the side connecting rod 309. The side connecting rod 309 is elastically and slidably assembled on one side of the jet cylinder 303.

[0033] In actual application, the rotating disc 301 is rotatably assembled on the external flow guide bin 202, and a sliding sealing structure is arranged between the rotating disc 301 and the external flow guide bin 202, so that the pumped cleaning liquid flows into the rotating disc 301 along the external flow guide bin 202, and then flows into the jet cylinder 303 along the rotating disc 301. The inner tooth ring 302 at the inner diameter end of the rotating disc 301 is in meshing connection with the third transmission wheel 209, so that when the internal flow guide bin 201 is in the locked state, the third transmission wheel 209 is engaged to drive the rotating disc 301 to rotate, so that the plurality of jet cylinders 303 rotate to clean the surface of the blade by the cleaning brush 308 at the bottom of the jet cylinder 303 during rotation. During the cleaning process, the cleaning brush 308 is elastically pressed on the surface of the blade, which increases the friction on one hand, and on the other hand, the bottom of the valve column 304 and the cavity bottom of the jet cylinder 303 are spaced apart. At this time, the cleaning liquid pumped into the inner cavity of the jet cylinder 303 flows through the inner pipe 305 to the bottom spray port 307, so that the cleaning liquid is sprayed on the surface of the blade along the bottom spray port 307. At the same time of flushing the stains on the surface of the blade, the second transmission wheel 208 is continuously used to clean the residual stains on the surface of the blade, and the movement of the mechanical arm realizes the cleaning work of the blade.

[0034] Please refer to Figure 5 and Figure 6 In a preferred embodiment of the present application, the cleaning assembly 3 further comprises a J-shaped rod 310, an outer moving disc 311, an inner moving disc 312, an inner pressing rod 313, an elastic buckle 314 and a reset tab 315. The J-shaped rod 310 is fixedly assembled at the end of the side connecting rod 309. The outer moving disc 311 is elastically and slidably assembled at the bottom of the external flow guide bin 202. The inner moving disc 312 is arranged in the main housing 101 and fixedly connected with the outer moving disc 311. The inner pressing rod 313 is fixedly arranged at one end of the inner moving disc 312. The elastic buckle 314 is fixedly assembled in the main housing 101, and one end of the elastic buckle 314 is provided with the reset tab 315. The reset tab 315 and the inner pressing rod 313 are in movable abutment.

[0035] In actual application, the J-shaped rod 310 is fixedly arranged at the end of the side connecting rod 309, when the buckle 210 is in the locking state, the cleaning brush 308 elastically abuts against the surface of the blade, at this time, the side connecting rod 309 moves along the positive direction of the third direction z, so that the J-shaped rod 310 moves synchronously and the J-shaped rod 310 and the outer moving disc 311 are arranged at intervals, when the plurality of jet cylinders 303 move to the section position of the blade, when the cleaning brush 308 rotates to the section end, the limiting surface at the bottom side of the cleaning brush 308 disappears, so that the cleaning brush 308 drives the connecting column 306 to move along the negative direction of the third direction z, and simultaneously drags the J-shaped rod 310 to move towards the outer moving disc 311, when the J-shaped rod 310 is pressed on the outer moving disc 311, the inner moving disc 312 and the inner pressing rod 313 are simultaneously pressed to move, so that the inner pressing rod 313 switches the locking state of the built-in flow guide bin 201 to the loosening state, so that the built-in flow guide bin 201 moves along the positive direction of the third direction z, simultaneously dragging the plurality of jet cylinders 303 to move away from the surface of the blade, so that the cleaning brush 308 is separated from the surface of the blade, preventing the continuous rotation from causing the section glass fiber wire harness to be further damaged.

[0036] In one case in the embodiment, one side of the sleeve 204 is fixedly provided with the buckle 210, so that when the built-in flow guide bin 201 moves along the negative direction of the third direction z, the buckle 210 is movably buckled on the elastic buckle 314, so that the built-in flow guide bin 201 is switched from the loosening state to the locking state, and when the inner pressing rod 313 moves along the negative direction of the third direction z, the inner pressing rod 313 is pressed on the reset tab 315, so that the bottom of the elastic buckle 314 is bent and then slides away from one side of the buckle 210, so that the built-in flow guide bin 201 is switched from the locking state to the loosening state again, and the elastic buckle 314 is made of an elastic material, which is not limited in type.

[0037] Please refer to Figure 7 In a preferred embodiment of the application, the cleaning assembly 3 further comprises a side sprayer 316, a side spray port 317, a side flow cavity 318 and a side cylinder hole 319, the side sprayer 316 is fixedly arranged at the outer diameter end of the jet cylinder 303, a plurality of side spray ports 317 are arranged on the side sprayer 316 in the circumferential direction, the side flow cavity 318 is arranged in the side spray port 317, and a plurality of side cylinder holes 319 are arranged on the cylinder wall of the jet cylinder 303, and the side flow cavity 318 and the side cylinder hole 319 are connected.

[0038] In actual application, the valve column 304 is slidably assembled in the inner cavity of the jet cylinder 303 through the connecting column 306. When the inner guide bin 201 is in the locking state, the valve column 304 and the cavity bottom of the jet cylinder 303 are spaced apart. At this time, the outer wall of the valve column 304 is slidably attached to one end of the side cylinder hole 319, so that the side cylinder hole 319 is in a blocked state, so that the cleaning liquid in the jet cylinder 303 flows towards the bottom spray port 307 side through the inner through pipe 305. When the inner guide bin 201 is switched from the locking state to the loosening state, the bottom of the valve column 304 abuts against the cavity bottom of the jet cylinder 303. Because the bottom aperture of the inner through pipe 305 and the bottom spray port 307 are misaligned, the bottom aperture of the inner through pipe 305 is blocked. At this time, the outer wall of the valve column 304 slides away from one side of the side cylinder hole 319, so that the cleaning liquid in the jet cylinder 303 flows along the side cylinder hole 319 to the side flow cavity 318, and is fan-shaped and obliquely sprayed to one side of the blade section through the side spray port 317.

[0039] In one case in the embodiment, the setting height of the side spray port 317 in the third direction z is greater than the setting height of the bottom spray port 307, so that the spray intensity acting on the blade surface is reduced. The spray pressure is 500-800 bar, the spray distance between the nozzle and the section is 20-30 cm, and the oblique angle between the spray port of the side spray port 317 and the blade is 30°-45°.
