Description
Technical Field
[0001] This invention relates to the field of wind power energy technology, and in particular to an intelligent cleaning device for the outer wall of a wind turbine tower. Background Technology
[0002] With social development and progress, the development of clean energy has received great attention, including various power generation methods such as solar power, hydropower and wind power. Wind power generation refers to converting the kinetic energy of wind into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy. The wind turbine rotates under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the wind turbine shaft. The generator rotates under the drive of the wind turbine shaft to generate electricity. The wind turbine is installed on the ground through a wind turbine tower, with the wind turbine and other power generation equipment installed at the top of the wind turbine tower.
[0003] Wind turbine towers are located outdoors for extended periods, making their surfaces prone to dirt accumulation. Without regular cleaning, this can lead to corrosion and damage to the outer walls, reducing the overall strength of the tower. Therefore, cleaning equipment is necessary. Current cleaning methods often employ a "spider-man" approach, suspending cleaning personnel with ropes for the cleaning process. This method is highly dangerous, time-consuming, labor-intensive, and inefficient. Some patented solutions utilize a ring-shaped sleeve fitted over the tower exterior. Cleaning tools are installed inside the sleeve, and a drive wheel or rope pulls the sleeve vertically, allowing the cleaning tools to clean the outer walls of the tower.
[0004] However, in this cleaning method, the annular sleeve moves straight up and down, supporting only vertical cleaning. But the wind turbine tower is wider at the bottom than at the top, and its outer wall is inclined. Therefore, the straight-up-down cleaning method has blind spots and is not thorough. Summary of the Invention
[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an intelligent cleaning device for the outer wall of wind turbine towers.
[0006] This invention provides an intelligent cleaning device for the outer wall of a wind turbine tower, comprising a cleaning mechanism fitted onto the outside of the tower body, the cleaning mechanism including:
[0007] An annular sleeve is fitted onto the outside of the tower body, with its inner wall parallel to the outer wall of the tower body.

[0018] According to the technical solution provided in the embodiments of this application, the rinsing mechanism further includes a switching assembly, the switching assembly comprising:
[0019] A blocking block having a first state and a second state; when in the first state, the blocking block blocks the top opening of the vertical pipe; when in the second state, the blocking block opens the top opening of the vertical pipe.
[0020] The opening and closing mechanism is used to drive the blocking block to switch between the first and second states.
[0021] According to the technical solution provided in the embodiments of this application, the opening and closing part includes:
[0022] The transmission frame includes a lower baffle located below the annular end cover. Two clamping plates are provided through the middle of the lower baffle. A limiting channel is provided between the two clamping plates. A connecting rod is slidably connected inside the limiting channel. The sealing block is installed at the bottom end of the connecting rod. An upper baffle is installed through the top of the two clamping plates extending out of the annular end cover.
[0023] Two opposing structures are symmetrically distributed on the opposite sides of the two clamping plates. The structure includes a second spring located at the top of the lower baffle. The top of the second spring is connected to the bottom surface of the annular end cap. A fixed pulley is located on the bottom surface of the annular end cap between the second spring and the clamping plate. A groove is provided in the middle of the clamping plate. A transmission rope is provided on the top surface of the lower baffle. The other end of the transmission rope extends upward and passes over the top of the fixed pulley, then passes through the groove and connects to the top of the connecting rod.
[0024] According to the technical solution provided in the embodiments of this application, a traction mechanism is installed at the top of the tower body. The traction mechanism is used to pull the upper baffle and drive the annular sleeve to move upward.
[0025] According to the technical solution provided in the embodiments of this application, the traction mechanism includes:
[0026] The traction unit includes a permanent magnet located at the top of the upper baffle and an electromagnet located above the permanent magnet, a traction rope at the top of the electromagnet, and a winding shaft connected to the traction rope at the top of the tower body.
[0027] The winding section is used to drive the winding shaft to rotate, thereby winding the traction rope and pulling the electromagnet upward.
[0028] According to the technical solution provided in the embodiments of this application, the outer wall of the annular sleeve is provided with a heating assembly, the heating assembly comprising:
[0029] Heating elements are fitted around the outer wall of the annular sleeve.
[0030] The first sealing part includes an arc-shaped flange located at the outer end of the sliding sleeve, and the arc-shaped flange is provided with a first gasket for extruding heating elements near the outer wall end of the annular sleeve.
[0031] The second sealing part includes a threaded cap that is threadedly installed on the inner end of the sliding sleeve. The threaded cap is provided with a second washer near the inner wall of the annular sleeve, and a third washer is provided at the inner end of the sliding sleeve away from the inner wall of the annular sleeve.
[0032] Compared with the prior art, the beneficial effects of the present invention are:
[0033] This invention features a cleaning sleeve with its axis parallel to the outer wall of the tower body, and an adjusting rod with its axis perpendicular to the tower body's axis. A sail is mounted at the end of the adjusting rod. By adjusting the swing angle of the sail, as the annular sleeve moves downward, the annular sleeve rotates under the influence of gravity and the sail, causing the cleaning sleeve to surround and clean the outer wall of the tower body. Furthermore, a first spring ensures that the cleaning sleeve remains in contact with the outer wall of the tower body. Compared to existing cleaning methods where the annular sleeve moves vertically up and down, this invention, through the deflection of the sail, causes the annular sleeve to rotate synchronously during its downward movement, allowing the cleaning sleeve to surround and clean the outer wall of the tower body. This ensures thorough cleaning of the outer surface of the tower body, eliminates cleaning dead zones, effectively improves cleaning efficiency, and guarantees excellent cleanliness.
[0034] In addition, a water storage chamber is set inside the annular sleeve, and a water outlet component is provided at the bottom. By adjusting the component, the water outlet is deflected. On the one hand, the water is used to rinse and make the cleaning sleeve wipe more thoroughly. On the other hand, by deflecting the direction of the water outlet, the water outlet direction is aligned with the rotation direction of the annular sleeve, thereby increasing the rotation speed and allowing the annular sleeve to rotate more times during descent. This allows for more thorough cleaning of the outer wall of the tower and avoids the situation where the annular sleeve descends too quickly and cannot be wiped in time. Furthermore, a filter component is provided at the top to absorb natural rainfall. Even further, a heating plate is provided on the outer wall of the annular sleeve to heat the water inside the water storage chamber. The warm water can better rinse away stains and improve wiping efficiency.
[0035] Based on the above, a traction mechanism, a sealing block, and an opening / closing section are provided. The traction mechanism pulls the upper baffle of the opening / closing section, causing the annular sleeve to sink due to gravity. Through a reverse structure, the connecting rod and the sealing block move downwards, blocking the inlet of the water outlet pipe. After the upper baffle is released, under the action of the second spring, the upper and lower baffles move downwards. Through the reverse structure, the connecting rod and the sealing block move upwards, opening the inlet of the water outlet pipe. This ensures that when the annular sleeve is pulled upwards, the water in the storage chamber will not leak. After the traction mechanism separates from the upper baffle, the water in the storage chamber is discharged, achieving an effective cleaning effect. Furthermore, the traction mechanism uses an electromagnet and a permanent magnet to pull the upper baffle. Because the annular sleeve rotates, if the traction rope is always connected to the upper baffle, the traction rope will interfere with the rotation of the annular sleeve. This connection method can more stably ensure the rotation of the annular sleeve, ensuring a thorough cleaning effect.
[0036] In summary, by rotating the annular sleeve as it moves downwards using a sail plate, a preliminary and circumferential cleaning effect is achieved. Building upon this, a water storage chamber, a water outlet assembly, and an adjustment assembly are added to increase the rotation speed. Furthermore, an electromagnet and a permanent magnet pull on the sealing block of the water outlet pipe, causing the traction rope to interfere with the rotation of the annular sleeve. Ultimately, this achieves rapid and stable rotation of the annular sleeve, allowing the cleaning sleeve to thoroughly clean the outer wall of the tower, reducing cleaning dead zones and improving cleaning efficiency.

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0062] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0063] Please refer to Figures 1-11An embodiment of the present invention provides an intelligent cleaning device for the outer wall of a wind turbine tower, including a cleaning mechanism 2 fitted outside the tower body 1. The cleaning mechanism 2 includes:
[0064] An annular sleeve 21 is fitted onto the outside of the tower body 1, with its inner wall parallel to the outer wall of the tower body 1.
[0065] Several wiping parts, including a cleaning sleeve 214 installed on the inner wall of the annular sleeve 21, the axial direction of the cleaning sleeve 214 is parallel to the outer wall of the tower body 1, and both ends of the cleaning sleeve 214 are connected to the inner wall of the annular sleeve 21 by a first spring 212.
[0066] Several rotating parts include several adjusting rods 22 installed on the outer wall of the annular sleeve 21. The axial direction of the adjusting rods 22 is perpendicular to the axial direction of the tower body 1. The outer wall of the adjusting rods 22 is provided with a sail plate 23.
[0067] The adjustment part is located on the annular sleeve 21 and is used to drive the adjustment rod 22 to rotate, thereby causing the sail 23 to swing.
[0068] This invention features a cleaning sleeve 214 with its axis parallel to the outer wall of the tower body 1, and an adjusting rod 22 with its axis perpendicular to the axis of the tower body 1. A sail 23 is mounted at the end of the adjusting rod 22. By adjusting the swing angle of the sail 23, when the annular sleeve 21 moves downwards, under the action of gravity and the sail 23, the annular sleeve 21 rotates, thereby causing the cleaning sleeve 214 to surround the outer wall of the cleaning tower body 1. Furthermore, the first spring 212 can always push the cleaning sleeve 214 to fit against the outer wall of the tower body 1. Compared to the existing cleaning method where the annular sleeve 21 moves vertically, this invention... The deflected sail 23 causes the annular sleeve 21 to rotate synchronously during its downward movement, so that the cleaning sleeve 214 surrounds the outer wall of the cleaning tower 1, which can fully clean the outer surface of the tower 1 without any cleaning dead corners, effectively improving cleaning efficiency and ensuring excellent cleanliness. Optionally, the inner wall and outer wall of the annular sleeve 21 have a first included angle 215, and the mounting shaft 213 is parallel to the inner wall of the annular sleeve 21, and thus the mounting shaft 213 is parallel to the outer wall of the tower 1. Therefore, after the first spring 212 retracts, the cleaning sleeve 214 installed on the mounting shaft 213 can stably clean the outer wall of the tower 1.
[0069] In some embodiments, the tail end of the adjusting rod 22 extends through into the interior of the annular sleeve 21. The adjusting part includes a first driven gear 24 disposed at the tail end of each adjusting rod 22. A first gear ring 25 is meshed and driven above the first driven gear 24. A first motor 27 is also disposed inside the annular sleeve 21. A first drive gear 28 that meshes and drives with the first gear ring 25 is mounted on the output shaft of the first motor 27.
[0070] refer to Figure 3 and Figure 4As shown, the first motor 27 is started, which drives the first drive gear 28 to rotate. Through gear meshing, the first gear ring 25 is driven to rotate, ultimately driving each first driven gear 24 to rotate, thus achieving the purpose of synchronously adjusting all adjusting rods 22. Optionally, the inner wall of the annular sleeve 21 is provided with a limiting sleeve 26. The limiting sleeve 26 is U-shaped, with both ends connected to the annular sleeve 21. Its interior fits with the first gear ring 25 to ensure the stability of the rotation of the first gear ring 25.
[0071] In some embodiments, the cleaning mechanism 2 further includes a limiting part, which includes a slide rod 211 disposed at both ends of each cleaning sleeve 214, an installation shaft 213 installed between the two slide rods 211, the cleaning sleeve 214 being rotatably mounted outside the installation shaft 213, and a sliding sleeve 210 slidably connected to the other end of the slide rod 211, the sliding sleeve 210 penetrating the side wall of the annular sleeve 21, and a first spring 212 being fitted outside the slide rod 211 and located between the installation shaft 213 and the sliding sleeve 210.
[0072] refer to Figures 2 to 4 As shown, the axis of the slide rod 211 is perpendicular to the inner wall of the annular sleeve 21 and the outer wall of the tower body 1. The first spring 212 pushes the mounting shaft 213 and the cleaning sleeve 214 to move and the cleaning sleeve 214 squeezes the outer wall of the tower body 1 for cleaning. The slide rod 211 moves along the sliding sleeve 210, which ensures the stability of the movement of the slide rod 211 and the mounting shaft 213, avoids deviation of the cleaning sleeve 214, and ensures that the cleaning sleeve 214 stably fits against the outer wall of the tower body 1 for wiping.
[0073] In some embodiments, a flushing mechanism 3 is further installed on the annular sleeve 21, the flushing mechanism 3 comprising:
[0074] The water storage chamber 31 is an annular cavity located between the outer wall and the inner wall of the annular sleeve 21. The top surface of the annular sleeve 21 is provided with an annular end cap 32 that seals the opening of the water storage chamber 31.
[0075] The water outlet assembly 5 is located at the bottom of the water storage chamber 31 and includes a water outlet pipe 51 that connects to the inside of the water storage chamber 31. The water outlet pipe 51 is composed of a vertical pipe and an inclined pipe. The inclined pipe extends downward towards the tower body 1 and a nozzle 52 is installed at the tail end of the inclined pipe. Optionally, a support wheel 10 is provided at the bottom end of the annular sleeve 21. The bottom end of the support wheel 10 is lower than the lowest point of the nozzle 52.
[0076] Adjustment component 7, located at the bottom of annular sleeve 21, is used to drive the vertical tube to rotate, thereby causing the inclined tube and nozzle 52 to rotate synchronously.
[0077] refer to Figure 3 and Figure 6As shown, by adjusting the component 7, the nozzle 52 is deflected. On the one hand, the water is used to rinse the cleaning sleeve 214 more thoroughly. On the other hand, the deflection of the nozzle 52 makes its water outlet direction consistent with the rotation direction of the annular sleeve 21, thereby increasing the rotation speed and allowing the annular sleeve 21 to rotate more times during descent. This allows for more thorough cleaning of the outer wall of the tower body 1 and avoids the situation where the annular sleeve 21 descends too quickly and cannot be wiped in time. Optionally, a sealing box 29 is provided inside the water storage chamber 31, and the first motor 27 can be installed inside the sealing box 29 to ensure the dryness and stable operation of the first motor 27. Optionally, the adjusting component 7 includes a second toothed ring 73 fitted outside the vertical pipe. A second drive gear 72 is meshed and driven on one side of the second toothed ring 73. A second motor 71 is provided at the bottom of the annular sleeve 21. The output shaft of the second motor 71 extends into the water storage chamber 31, and the second drive gear 72 is installed on the top of the output shaft.
[0078] In some embodiments, the rinsing mechanism 3 further includes a plurality of filter components 4 disposed on the annular end cap 32. The filter components 4 include a filter box 43 inserted through the annular end cap 32. The bottom end of the filter box 43 is filled with filter material 45. A support net 44 is provided through the bottom end of the filter box 43. A mouth-shaped plate 41 is provided at the top edge of the filter box 43. A first filter screen 42 is installed at the top of the mouth-shaped plate 41.
[0079] refer to Figure 4 and Figure 9 As shown, natural rainwater falls into the water storage chamber 31 through the first filter screen 42, filter material 45, and support net 44, collecting natural rainwater without the need for additional water replenishment, reducing the cost of transporting water and improving water use efficiency. Furthermore, the area of the orifice plate 41 is larger than that of the filter box 43, and the orifice plate 41 and the first filter screen 42 are provided with first through holes. The annular end cap 32 is provided with corresponding first screw holes, which can be connected by screws passing through the first through holes and the first screw holes, realizing the detachable installation of the orifice plate 41 and enabling the periodic replacement of the first filter screen 42 and filter material 45.
[0080] In some embodiments, the flushing mechanism 3 further includes a switch assembly 6, which includes:
[0081] The sealing block 61 has a first state and a second state. When it is in the first state, the sealing block 61 blocks the top opening of the vertical pipe. When it is in the second state, the sealing block 61 opens the top opening of the vertical pipe.
[0082] The opening and closing mechanism is used to drive the blocking block 61 to switch between the first state and the second state.
[0083] like Figure 6As shown, the top opening of the vertical pipe is blocked by the sealing block 61 to achieve the purpose of water outlet and water shut-off, so that the user can select the state of the sealing block 61 according to the actual situation and achieve selective water spraying; optionally, an electric push rod is set on the ground of the annular end cap 32, and the sealing block 61 is moved in the vertical direction by the electric push rod.
[0084] In some embodiments, the opening and closing part includes:
[0085] The transmission frame includes a lower baffle 64 located below the annular end cover 32. Two clamping plates 67 are provided through the middle of the lower baffle 64. A limiting channel 68 is provided between the two clamping plates 67. A connecting rod 62 is slidably connected inside the limiting channel 68. A sealing block 61 is installed at the bottom end of the connecting rod 62. An upper baffle 69 is installed through the top of the two clamping plates 67 and extends out of the annular end cover 32.
[0086] Two opposing structures are symmetrically distributed on the opposite sides of the two clamping plates 67. The structure includes a second spring 65 located at the top of the lower baffle 64. The top of the second spring 65 is connected to the bottom surface of the annular end cap 32. A fixed pulley 610 is located on the bottom surface of the annular end cap 32 between the second spring 65 and the clamping plate 67. A wire groove 612 is provided in the middle of the clamping plate 67. A transmission rope 611 is provided on the top surface of the lower baffle 64. The other end of the transmission rope 611 extends upward and passes over the top of the fixed pulley 610, then passes through the wire groove 612 and connects to the top of the connecting rod 62.
[0087] refer to Figures 6 to 8 As shown, when the upper baffle 69 is pulled upward, the lower baffle 64 moves upward along with it, and the second spring 65 contracts and deforms. As the lower baffle 64 moves upward, the first end of the transmission rope 611 moves upward. At this time, under the action of gravity, the connecting rod 62 and the sealing block 61 move downward, and drive the second end of the transmission rope 611 to move downward, so that the sealing block 61 moves downward and is inserted into the upper opening of the vertical pipe, thus playing a sealing role.
[0088] When the upper baffle 69 is released, the second spring 65 needs to return to its original shape, causing the upper baffle 69 and the lower baffle 64 to move downwards. The first end of the transmission rope 611 moves downwards, and under the action of the fixed pulley 610, the second end of the transmission rope 611 pulls the connecting rod 62 upwards, so that the sealing block 61 moves upwards and separates from the upper opening of the vertical pipe, thereby releasing the water.
[0089] Optionally, refer to Figure 3As shown, the connecting rod 62 is provided with a relief groove 63 in the middle. The relief groove 63 fits with the sliding sleeve 210 or the adjusting rod 22. Therefore, when the connecting rod 62 moves upward, the sliding sleeve 210 or the adjusting rod 22 is inside the relief groove 63, thus ensuring the stability of the connecting rod 62 during the movement process. Preferably, in order to avoid damage caused by excessive compression of the second spring 65, a compensation block 66 is provided at the top of the lower baffle 64. The top of the compensation block 66 can be pressed against the ground of the annular end cap 32 to ensure that the second spring 65 will not be damaged by excessive compression.
[0090] In some embodiments, a traction mechanism 8 is installed at the top of the tower body 1. The traction mechanism 8 is used to pull the upper baffle 69, causing the annular sleeve 21 to move upward. Figures 2 to 8 As shown, the traction mechanism 8 pulls the upper baffle 69. During the lifting process, the annular sleeve 21 moves downward due to gravity, which means that the upper baffle 69 moves upward. This pulls the upper baffle 69 upward, allowing the sealing block 61 to be inserted into the upper opening of the vertical pipe, ensuring that the water does not leak during the lifting process. As the annular sleeve 21 moves downward, it loses the pull of the traction mechanism 8, and the second spring 65 pulls the upper baffle 69 back to its original position, opening the upper opening of the vertical pipe.
[0091] In some embodiments, the traction mechanism 8 includes:
[0092] The traction unit includes a permanent magnet 811 located at the top of the upper baffle 69, an electromagnet 810 located above the permanent magnet 811, a traction rope 89 at the top of the electromagnet 810, and a winding shaft 83 connected to the traction rope 89 at the top of the tower body 1.
[0093] The winding section is used to drive the winding shaft 83 to rotate, thereby driving the traction rope 89 to wind up and pulling the electromagnet 810 to move upward.
[0094] refer to Figure 2 , Figure 7 and Figure 11As shown, by supplying power to the electromagnet 810, magnetic poles are formed at both ends of the electromagnet 810, which attract each other to the permanent magnet 811. When the winding shaft 83 rotates, the traction rope 89 winds up, and the electromagnet 810 drives the permanent magnet 811 and the upper baffle 69 to move upwards, thus pulling the upper baffle 69 and the annular sleeve 21 upwards. During cleaning, simply disconnecting the power supply to the electromagnet 810 causes the permanent magnet 811 to lose its magnetic attraction. Under the action of the second spring 65, the lower baffle 64 resets, driving the connecting rod 62 and the sealing block 61 to move upwards. The sealing block 61 then opens the upper opening of the vertical pipe, allowing the annular sleeve 21 to not only move downwards smoothly but also achieve the effect of spraying water. Although the rotation of the annular sleeve 21 causes the position of the permanent magnet 811 to change, because the electromagnet 810 and the permanent magnet 811 are in a one-to-one correspondence, the electromagnet 810 will be attracted to the nearest permanent magnet 811, thus achieving the purpose of attraction and pulling.
[0095] In some embodiments, the outer wall of the annular sleeve 21 is provided with a heating assembly 9, the heating assembly 9 comprising:
[0096] Heating element 96 is fitted around the outer wall of annular sleeve 21.
[0097] The first sealing part includes an arc-shaped flange 91 located at the outer end of the sliding sleeve 210, and a first gasket 92 for the extrusion heating plate 96 is provided on the arc-shaped flange 91 near the outer wall end of the annular sleeve 21.
[0098] The second sealing part includes a threaded cap 93 that is threadedly installed on the inner end of the sliding sleeve 210. The end of the threaded cap 93 near the inner wall of the annular sleeve 21 is provided with a second washer 94, and the end of the inner end of the sliding sleeve 210 away from the inner wall of the annular sleeve 21 is provided with a third washer 95.
[0099] like Figure 10 As shown, the heating element 96 can heat the water inside the annular sleeve 21. The heated water can better dissolve stains, making it easier to clean the outer wall of the tower body 1 through the cleaning sleeve 214. Optionally, the heating element 96 can be a heating appliance or an annular piece made of black material. The heating appliance can heat the inner wall of the annular sleeve 21 by directly energizing it, while the black annular piece can absorb light energy and convert it into heat energy to heat the water.
[0100] In addition, the heating element 96 is installed by pressing the heating element 96 with the arc flange 91, and the sliding sleeve 210 can be installed by the first sealing part and the second sealing part. The stability of the sliding sleeve 210 after installation can be ensured by the first washer 92, the second washer 94 and the third washer 95, which can ensure the stable movement of the slide rod 211 and prevent water leakage inside the water storage chamber 31.
[0101] In some embodiments, the winding section includes a baffle plate 81 fitted onto the top of the tower body 1. The bottom end of the baffle plate 81 is provided with a plurality of bearing seats 82 for mounting the winding shafts 83. The ends of adjacent winding shafts 83 are evenly distributed with a plurality of transmission rods 84, and adjacent winding shafts 83 are connected by transmission rods 84.
[0102] The bottom of the baffle plate 81 is equipped with a third motor 88. The output shaft of the third motor 88 is connected to a reducer 86. The output shaft of the reducer 86 is connected to a third drive gear 87. A third driven gear 85 that meshes and is transmitted with the third drive gear 87 is mounted on one of the winding shafts 83.
[0103] refer to Figure 2 and Figure 11 As shown, by starting the third motor 88, the third drive gear 87 is driven to rotate through the reducer 86, which in turn drives the third driven gear 85 and the corresponding winding shaft 83 to rotate. The transmission rods 84 at both ends of the winding shaft 83 will drive the other winding shafts 83 to rotate, ultimately achieving the purpose of synchronous rotation of all winding shafts 83. This can then drive all traction ropes 89 to be wound up or released synchronously. The reducer 86 is used to reduce the speed and increase the torque, making it easier to drive the winding shaft 83 to rotate.
[0104] In some embodiments, a programmable controller is provided inside the tower body 1. After programming, it can sequentially start or stop corresponding electrical appliances as needed to achieve automated operation. Furthermore, a control module can be installed on the annular sleeve 21 and the ground of the shield plate 81. The control module has a wireless signal transceiver, a microprocessor and a power supply. The programmable controller is connected to the microprocessor via wireless signal and electrical signal, eliminating the need for open wire connection and avoiding interference from open wires on the rotation of the annular sleeve 21.
[0105] During the use of this device:
[0106] Step 1: Turn off electromagnet 810. After it loses its magnetism, permanent magnet 811, upper baffle 69 and annular sleeve 21 move downwards synchronously.
[0107] Step two: During the downward movement, after the permanent magnet 811 loses its magnetic attraction, under the action of the second spring 65, the lower baffle 64 resets, causing the connecting rod 62 and the sealing block 61 to move upward. Consequently, the sealing block 61 opens the upper opening of the vertical pipe, allowing the annular sleeve 21 to not only move downward smoothly but also achieve the effect of spraying water. During the downward movement, the annular sleeve 21 rotates due to the action of the sail plate 23. During the rotation, the cleaning sleeve 214, which abuts against the outer wall of the tower body 1, cleans the outer wall of the tower body 1.
[0108] Step 3: After the support wheel 10 contacts the ground, the annular sleeve 21 will not continue to move downwards, completing the cleaning process. Then, the traction rope 89 is released to make the electromagnet 810 move downwards.
[0109] Step 4: Activate electromagnet 810, which will attract the corresponding permanent magnet 811 after generating magnetism.
[0110] Step 5: Start the third motor 88 of the traction mechanism 8, drive the traction rope 89 to circle, and then drive the electromagnet 810 and permanent magnet 811 to move upward. During the movement, the upper baffle 69 is pulled and the sealing block 61 is inserted into the opening on the vertical pipe of the water outlet pipe 51.
[0111] Step six: After the traction rope 89 pulls the annular sleeve 21 to the top of the tower body 1, it is left to stand and wait for the next use.
