Description

Technical Field

[0001] The present invention relates to the technical field of dry ice spraying structures for tower barrel cleaning equipment, and particularly to a dry ice spraying structure for cleaning wind power tower barrels. Background Technique

[0002] During long-term operation of wind power generation, engine oil will flow downward along the outer wall of the tower barrel from the inside of the nacelle and spread over the entire tower barrel wall. Under the action of the wind, dust will adhere to the oil-stained tower wall, and the white tower barrel will become a "black" tower barrel, seriously affecting the aesthetics of the wind turbine, as well as the brand quality reputation of the wind turbine manufacturer and the maintenance management of the wind farm. Therefore, the tower barrel must be cleaned.

[0003] Generally, when spraying and cleaning the tower barrel, it is basically carried out by workers holding a spray gun to spray and clean the surface of the tower barrel. Since the tower barrel is cylindrical and has a relatively high height, and the spraying area of the pelvis is small, it is difficult to cover the entire circumferential surface of the tower barrel, resulting in the need to clean the tower barrel around during cleaning, which easily increases the labor intensity of workers and is also prone to uneven spraying. Summary of the Invention

[0004] The purpose of the present invention is to provide a dry ice spraying structure for cleaning wind power tower barrels to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a dry ice spraying structure for cleaning wind power tower barrels, including a circular base. A tower barrel is fixedly installed on the top of the circular base. A U-shaped cylinder is rotatably sleeved on the tower barrel. A plurality of tooth blocks are fixedly installed on the inner wall of the U-shaped cylinder. It further includes: An adjusting mechanism. The adjusting mechanism includes a driving motor fixedly installed on the top of the circular base. A rotating shaft is fixedly installed on the output shaft of the driving motor. A transmission gear is fixedly sleeved on the rotating shaft. The transmission gear meshes with a plurality of tooth blocks. A disc is rotatably sleeved on the tower barrel. Two support rods are fixedly installed at the bottom of the disc. The bottom ends of the two support rods are both fixedly connected to the U-shaped cylinder.

[0006] Further, an adjusting gear is fixedly sleeved on the outer wall of the threaded rod. An annular gear is fixedly sleeved on the outer wall of the tower barrel. The adjusting gear meshes with the annular gear.

[0007] Furthermore, a strip-shaped block is fixedly installed on the back surface of the sector-shaped storage bin. Two through grooves are formed in the inner wall of the sector-shaped storage bin. A T-shaped material spraying groove is formed in the strip-shaped block, and both of the two through grooves communicate with the T-shaped material spraying groove.

[0008] Furthermore, a display mechanism is arranged on the threaded rod. The display mechanism includes an adaptive spring sleeved on the threaded rod. The top end of the adaptive spring is fixedly connected with the disc. An adaptive plate is sleeved on the threaded rod, and the bottom end of the adaptive spring is fixedly connected with the adaptive plate.

[0009] Furthermore, a U-shaped sliding plate is fixedly installed at the bottom of the disc. An L-shaped prompting block is slidably sleeved on the U-shaped sliding plate. The bottom end of the L-shaped prompting block is hingedly installed with a transmission frame. The front surface of the transmission frame is hinged with the adaptive plate, and the tower barrel penetrates through the transmission frame.

[0010] Furthermore, a spraying mechanism is arranged at the bottom of the sector-shaped storage bin. The spraying mechanism includes a one-way valve fixedly installed at the bottom of the sector-shaped storage bin. A feed pipe is fixedly installed in the one-way valve. The top end of the feed pipe extends into the sector-shaped storage bin. A pressurizing spring is fixedly installed on the inner bottom wall of the sector-shaped storage bin. The top end of the pressurizing spring is fixedly installed with a pressurizing sector plate. The feed pipe penetrates through the pressurizing sector plate and is slidably connected with the pressurizing sector plate.

[0011] Furthermore, a movable spring is fixedly installed on the inner top wall of the sector-shaped storage bin. The bottom end of the movable spring is fixedly installed with a movable sector plate. The movable sector plate is slidably connected with the sector-shaped storage bin, and the movable sector plate is distributed below the through grooves.

[0012] Furthermore, T-shaped grooves are respectively formed in the left inner wall and the right inner wall of the sector-shaped storage bin.

Triangular plates are respectively fixedly installed at the top ends of the two T-shaped rods.

[0013] The present invention has the following beneficial effects: (1)A dry ice spraying structure for cleaning a wind power generation tower barrel of the present invention. When in use, first, sufficient dry ice is filled into the fan-shaped storage box through a one-way valve and a feed pipe. Then, the driving motor is started. The driving motor drives the rotating shaft to rotate, the rotating shaft drives the transmission gear to rotate, and the transmission gear drives the U-shaped cylinder to rotate forward under the action of several tooth blocks. The U-shaped cylinder drives the support rod to rotate, and the threaded rod rotates around the tower barrel. The threaded rod will drive the threaded rod to rotate self-rotatingly under the action of the adjusting gear and the annular gear. The self-rotation of the threaded rod will drive the fan-shaped storage box to rise. When the driving motor rotates reversely, the fan-shaped storage box will rotate around the outer wall of the tower barrel and descend simultaneously under the rotation of the threaded rod and the U-shaped cylinder, facilitating the dry ice spraying and cleaning of the surface of the tower barrel, saving the manual cleaning workload, and thus improving the efficiency of the cleaning work; (2)A dry ice spraying structure for cleaning a wind power generation tower barrel of the present invention. During the rising process of the fan-shaped storage box, the T-shaped rod will be driven to rise. The T-shaped rod will drive the triangular plate to rise. When the triangular plate contacts the L-shaped contact rod, the triangular plate will move away from the fan-shaped storage box under the action of its inclined surface. The triangular plate will drive the T-shaped rod into the T-shaped groove. At this time, the T-shaped rod will leave the movable fan-shaped plate. Due to the relatively high pressure in the fan-shaped storage box, the gas in the fan-shaped storage box will push the movable fan-shaped plate upward. When the movable fan-shaped plate passes through the through groove, the dry ice will be sprayed through the through groove and the T-shaped spraying groove for cleaning work; (3)A dry ice spraying structure for cleaning a wind power generation tower barrel of the present invention. During the rising process of the fan-shaped storage box, the fan-shaped storage box will contact and push the adaptation plate to rise. At this time, the adaptation spring will undergo a compressive deformation. After the fan-shaped storage box leaves the thread on the threaded rod, it will be affected by the elastic force of the adaptation spring. The adaptation plate will hold the fan-shaped storage box to make the fan-shaped storage box in a semi-disengaged thread state. At this time, the fan-shaped storage box will not affect the normal rotation of the threaded rod. The adaptation plate will drive the transmission frame to rise, and the transmission frame will drive the L-shaped prompt block to move away from the fan-shaped storage box. When the L-shaped prompt block moves to the maximum distance, the raised block of the L-shaped prompt block will be exposed outside the disc. At this time, the staff can observe from the bottom of the tower barrel upward to judge whether the fan-shaped storage box has reached the topmost position; (4)A dry ice spraying structure for cleaning a wind power generation tower barrel of the present invention. After the fan-shaped storage box rotates and descends to complete the spraying and cleaning of the tower barrel, manually pull the T-shaped rods on both sides of the fan-shaped storage box to make the two T-shaped rods return to the T-shaped groove again. Since the dry ice in the fan-shaped storage box has been sprayed out, the pressure in the fan-shaped storage box is the same as the external pressure. At this time, the movable fan-shaped plate will return to the position below the through groove under the elastic force of the movable spring. Then, release the T-shaped rod, and the T-shaped rod will fall above the two movable fan-shaped plates to complete the locking purpose again. At this time, the fan-shaped storage box returns to the sealed state, facilitating the filling of dry ice for the next use.

[0014] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown, the present invention is a dry ice spraying structure for cleaning a wind power generation tower barrel, including a circular base 1. A tower barrel 2 is fixedly installed on the top of the circular base 1. A U-shaped cylinder 3 is rotatably sleeved on the tower barrel 2. A plurality of tooth blocks 4 are fixedly installed on the inner wall of the U-shaped cylinder 3. It further includes: An adjusting mechanism 5, the adjusting mechanism 5 includes a driving motor 501 fixedly installed on the top of the circular base 1. A rotating shaft 502 is fixedly installed on the output shaft of the driving motor 501. A transmission gear 503 is fixedly sleeved on the rotating shaft 502. The transmission gear 503 meshes with a plurality of tooth blocks 4. A disc 504 is rotatably sleeved on the tower barrel 2. Two support rods 505 are fixedly installed at the bottom of the disc 504. The bottom ends of the two support rods 505 are both fixedly connected to the U-shaped cylinder 3. A threaded rod 506 is rotatably installed at the bottom of the disc 504. The bottom end of the threaded rod 506 is rotatably connected to the U-shaped cylinder 3. A sector-shaped storage box 507 is threadedly sleeved on the threaded rod 506. The two support rods 505 both penetrate through the sector-shaped storage box 507 and are both slidably connected to the sector-shaped storage box 507.

[0020] As Figure 3 shown, an adjusting gear 508 is fixedly sleeved on the outer wall of the threaded rod 506. An annular gear 509 is fixedly sleeved on the outer wall of the tower barrel 2. The adjusting gear 508 meshes with the annular gear 509.

[0021] The U-shaped cylinder 3 drives the support rod 505 to rotate. The threaded rod 506 rotates around the tower barrel 2. The threaded rod 506 will drive the threaded rod 506 to rotate by itself under the action of the adjusting gear 508 and the annular gear 509. The self-rotation of the threaded rod 506 will drive the sector-shaped storage box 507 to rise.

[0022] As Figure 5 shown, a strip-shaped block 510 is fixedly installed on the back of the sector-shaped storage box 507. Two through slots 511 are opened on the inner wall of the sector-shaped storage box 507. A T-shaped spraying groove 512 is opened in the strip-shaped block 510. Both of the two through slots 511 communicate with the T-shaped spraying groove 512.

[0023] The sector-shaped storage box 507 will rotate around the outer wall of the tower barrel 2 and descend simultaneously under the rotation action of the threaded rod 506 and the U-shaped cylinder 3. Dry ice will be ejected through the through slots 511 and the T-shaped spraying groove 512 for cleaning work.

[0024] As Figure 7 shown, a display mechanism 6 is provided on the threaded rod 506. The display mechanism 6 includes an adaptation spring 601 sleeved on the threaded rod 506. The top end of the adaptation spring 601 is fixedly connected to the disc 504. An adaptation plate 602 is sleeved on the threaded rod 506. The bottom end of the adaptation spring 601 is fixedly connected to the adaptation plate 602.

[0025] The sector-shaped storage bin 507 will contact and push the adaptation plate 602 to rise. At this time, the adaptation spring 601 undergoes a compressive deformation. After the sector-shaped storage bin 507 leaves the thread on the threaded rod 506, it will be affected by the elastic force of the adaptation spring 601. The adaptation plate 602 will hold against the sector-shaped storage bin 507 to make the sector-shaped storage bin 507 in a semi-disengaged thread state. At this time, the sector-shaped storage bin 507 will not affect the normal rotation of the threaded rod 506.

[0026] As Figure 8 shown, a U-shaped sliding plate 603 is fixedly installed at the bottom of the disc 504. An L-shaped prompt block 604 is slidably sleeved on the U-shaped sliding plate 603. The bottom of the L-shaped prompt block 604 is hingedly installed with a transmission frame 605. The front surface of the transmission frame 605 is hinged to the adaptation plate 602. The tower barrel 2 passes through the transmission frame 605.

[0027] The adaptation plate 602 will drive the transmission frame 605 to rise. The transmission frame 605 will drive the L-shaped prompt block 604 to move away from the sector-shaped storage bin 507. When the L-shaped prompt block 604 moves to the maximum distance, the protruding block of the L-shaped prompt block 604 will be exposed outside the disc 504. At this time, the staff can observe upward from the bottom of the tower barrel 2 to judge whether the sector-shaped storage bin 507 reaches the topmost position.

[0028] As Figure 5 shown, a spraying mechanism 7 is provided at the bottom of the sector-shaped storage bin 507. The spraying mechanism 7 includes a one-way valve 701 fixedly installed at the bottom of the sector-shaped storage bin 507. A feed pipe 702 is fixedly installed inside the one-way valve 701. The top end of the feed pipe 702 extends into the sector-shaped storage bin 507. A pressurizing spring 703 is fixedly installed on the inner wall of the bottom of the sector-shaped storage bin 507. The top end of the pressurizing spring 703 is fixedly installed with a pressurizing sector plate 704. The feed pipe 702 passes through the pressurizing sector plate 704 and is slidably connected to the pressurizing sector plate 704.

[0029] During use, first, sufficient dry ice is filled into the sector-shaped storage bin 507 through the one-way valve 701 and the feed pipe 702. The one-way valve 701 can effectively prevent the filled dry ice from escaping and improve the sealing performance of the sector-shaped storage bin 507.

[0030] As Figure 5As shown, a movable spring 705 is fixedly installed on the top inner wall of the fan-shaped storage box 507, and a movable fan-shaped plate 706 is fixedly installed on the bottom end of the movable spring 705. The movable fan-shaped plate 706 is slidably connected to the fan-shaped storage box 507, and the movable fan-shaped plate 706 is distributed below the through groove 511.

[0031] Since the dry ice in the fan-shaped storage box 507 has been sprayed, the pressure in the fan-shaped storage box 507 is consistent with the external pressure. At this time, the movable fan-shaped plate 706 will return to the lower position of the through groove 511 again under the elastic force of the movable spring 705.

[0032] like Figure 7 As shown, T-slots 707 are respectively provided on the left inner wall and the right inner wall of the fan-shaped storage box 507, and T-rods 708 are respectively slidably installed in the two T-slots 707, and the ends of the two T-rods 708 that are away from each other extend to the outside of the fan-shaped storage box 507, and the two T-rods 708 are respectively fixedly sleeved with fixing sleeves 709, and the two T-rods 708 are respectively sleeved with closing springs 710, and the ends of the two closing springs 710 that are close to each other are fixedly connected to the fan-shaped storage box 507, and the ends of the two closing springs 710 that are away from each other are respectively fixedly connected to the two fixing sleeves 709, and two L-shaped contact rods 711 are fixedly installed on the bottom of the disk 504, and triangular plates 712 are respectively fixedly installed on the tops of the two T-rods 708.

[0033] During the rising process of the fan-shaped storage box 507, the T-shaped rod 708 will be driven to rise, and the T-shaped rod 708 will drive the triangular plate 712 to rise. When the triangular plate 712 contacts the L-shaped contact rod 711, the triangular plate 712 will move away from the fan-shaped storage box 507 under the action of its inclined surface, and the triangular plate 712 will drive the T-shaped rod 708 to enter the T-shaped groove 707. At this time, the T-shaped rod 708 will leave the movable fan-shaped plate 706. Since the pressure in the fan-shaped storage box 507 is relatively high, the gas in the fan-shaped storage box 507 will push the movable fan-shaped plate 706 upward.

[0034] In use, first, sufficient dry ice is filled into the sector-shaped storage bin 507 through the one-way valve 701 and the feed pipe 702. Then, the drive motor 501 is started. The drive motor 501 drives the rotating shaft 502 to rotate, the rotating shaft 502 drives the transmission gear 503 to rotate, and the transmission gear 503 drives the U-shaped cylinder 3 to rotate forward under the action of a number of tooth blocks 4. The U-shaped cylinder 3 drives the support rod 505 to rotate, and the threaded rod 506 rotates around the tower barrel 2. The threaded rod 506 will drive the threaded rod 506 to rotate on its own under the action of the adjusting gear 508 and the annular gear 509. The self-rotation of the threaded rod 506 will drive the sector-shaped storage bin 507 to rise. When the drive motor 501 rotates in reverse, the sector-shaped storage bin 507 will rotate around the outer wall of the tower barrel 2 and descend simultaneously under the rotation of the threaded rod 506 and the U-shaped cylinder 3, which is convenient for dry ice jet cleaning of the surface of the tower barrel 2, saving the manual cleaning workload and thus improving the efficiency of the cleaning work. During the rising process of the sector-shaped storage bin 507, the T-shaped rod 708 will be driven to rise. The T-shaped rod 708 will drive the triangular plate 712 to rise. When the triangular plate 712 contacts the L-shaped contact rod 711, the triangular plate 712 will move away from the sector-shaped storage bin 507 under the action of its inclined surface. The triangular plate 712 will drive the T-shaped rod 708 into the T-shaped groove 707. At this time, the T-shaped rod 708 will leave the movable sector plate 706. Due to the relatively high pressure in the sector-shaped storage bin 507, the gas in the sector-shaped storage bin 507 will push the movable sector plate 706 upward. When the movable sector plate 706 passes through the through groove 511, the dry ice will be ejected through the through groove 511 and the T-shaped spraying groove 512 for cleaning work. The adapting plate 602 will hold the fan-shaped storage box 507 so that the fan-shaped storage box 507 is in a semi-disengaged threaded state. At this time, the fan-shaped storage box 507 will not affect the normal rotation of the threaded rod 506, and the adapting plate 602 will drive the transmission frame 605 to rise, and the transmission frame 605 will drive the L-shaped prompting block 604 to move in the direction away from the fan-shaped storage box 507. When the L-shaped prompting block 604 moves to the maximum distance, the protruding block of the L-shaped prompting block 604 will be exposed to the periphery of the disc 504. At this time, the staff can When the spray cleaning of the tower 2 is completed, the T-shaped storage box 507 is manually opened, and the two T-shaped bars 708 on both sides of the tower 2 are returned to the T-shaped slots 707. Since the dry ice in the tower 2 has been sprayed, the pressure in the tower 2 is consistent with the pressure in the outside world. At this time, the movable fan plate 706 can be returned to the lower position of the through groove 511 under the elastic force of the movable spring 705, and then the T-shaped bar 708 is released, and the T-shaped bar 708 can fall above the two movable fan plates 706, completing the purpose of locking again. At this time, the fan-shaped storage box 507 returns to the sealed state again, which is convenient for charging dry ice for use next time.
