[0040] Referring to Figures 1 and 2, a cleaning vehicle provided in an embodiment of the present application. Before introducing the cleaning vehicle, a partial structure of a generator is briefly introduced. The generator includes a stator and a rotor inserted in the stator. There is an air gap between the stator and the rotor. The rotor can rotate around a central axis in the stator. After the generator is used for a long time, the inner surface of the stator and the ventilation holes of the stator, the outer surface of the rotor and the ventilation holes of the rotor will accumulate certain stains, and there will also be certain foreign matter in the air gap. Both the stains and foreign matter will affect the normal operation of the generator.

[0041] Therefore, it is necessary to clean the stator and rotor of the generator regularly, and the cleaning vehicle provided by the embodiment of the present invention can clean the inner surface of the stator and the outer surface of the rotor, which is described in detail below.

[0042] To this end, referring to Figures 1 and 2, the present application provides a cleaning vehicle that can enter the air gap between the rotor and the stator of the engine through the outside, so as to clean the rotor and the stator at the same time without pulling out the rotor. In order to clean the rotor and the stator at the same time, the cleaning vehicle includes a first cleaning module 10 and a second cleaning module 20.

[0043] The first cleaning module 10 is magnetic, and a first suction port 111 is provided on one side of the first cleaning module 10 in the first direction X, and the cleaning module 10 can clean the surface of the first object to be cleaned through the first suction port 111. The second cleaning module 20 is movably mounted on the first cleaning module 10, and the second cleaning module 20 can move relative to the first cleaning module 10 along the first direction X, and a second suction port is provided on one side of the second cleaning module 20 in the first direction X, and the second suction port 21 is arranged in the opposite direction to the first suction port 111, and the second cleaning module 20 can clean the second object to be cleaned through the second suction port 21.

[0044] Among them, when the cleaning vehicle is used to clean the generator, the first part to be cleaned can be a stator, and the second part to be cleaned can be a rotor. The first direction X is the radial direction of the stator / rotor, that is, the first cleaning module 10 is capable of being abutted against the stator surface on a side provided with a first dust suction port 111, and the second cleaning module 20 is capable of being abutted against the rotor surface on a side provided with a second dust suction port 21. Based on this, when the cleaning vehicle is located in the air gap of the generator, the first cleaning module 10 can be magnetically adsorbed on the stator surface and clean the stator surface through the first dust suction port 111, and the second cleaning module 20 can move relative to the first cleaning module 10 in a direction close to the rotor until it abuts against the rotor surface, so that the second cleaning module 20 can clean the rotor surface through the second dust suction port 21.

[0045] Specifically, after the cleaning vehicle enters the air gap from the outside, the first cleaning module 10 is first controlled to be magnetically adsorbed on the stator surface, and then the second cleaning module 20 is gradually moved until the second cleaning module 20 contacts the rotor surface. In this way, the first cleaning module 10 can be stably magnetically adsorbed on the stator surface, making the movement of the cleaning vehicle on the stator and rotor surfaces more stable, thereby ensuring the stability of the cleaning vehicle during operation, and the stator can be cleaned through the first dust suction port 111 of the first cleaning module 10. At the same time, the position of the second cleaning module 20 can be moved so that the second cleaning module 20 can be stably close to the rotor surface to clean the rotor surface through the second dust suction port 21. That is, while ensuring the stability of the cleaning vehicle during operation, the stator and rotor can also be cleaned by the cleaning vehicle at the same time, thereby effectively improving the cleaning efficiency of the generator, and effectively ensuring and improving the performance of the cleaning vehicle.

[0046] It should be noted that the following description only focuses on the case where the cleaning vehicle is used to clean the generator, the first part to be cleaned is the stator, and the second part to be cleaned is the rotor. The cleaning vehicle can be used for cleaning the generator but is not limited to other equipment with smaller gaps. The first part to be cleaned and the second part to be cleaned can be selected according to actual usage requirements and are not limited here.

[0047] In some embodiments of the present application, the cleaning vehicle further includes a first connecting rod assembly 30 and a second connecting rod assembly 31, wherein the first connecting rod assembly 30 includes a first end 32 and a second end 33 opposite to each other along the length direction, and the second connecting rod assembly 31 includes a third end 34 and a fourth end 35 opposite to each other along the length direction. The first end 32 and the third end 34 are both hinged to the second cleaning module 20 and arranged at intervals along the second direction Y, and the second end 33 and the fourth end 35 are both hinged to the first cleaning module 10 and can be controlled to approach or move away along the second direction Y. The first direction X and the second direction Y intersect. Preferably, the first direction X and the second direction Y are perpendicular.

[0048] In this way, when the second end 33 and the fourth end 35 are close to each other, the second cleaning module 20 will gradually move away from the first cleaning module 10 under the joint action of the first connecting rod assembly 30 and the second connecting rod assembly 31, that is, the second cleaning module 20 will gradually rise, and then, when the first cleaning module 10 is adsorbed on the stator surface, by making the second end 33 and the fourth end 35 close to each other, the height of the second cleaning module 20 is increased, and then the second cleaning module 20 gradually approaches the rotor surface until it is in contact with the rotor surface, so that the rotor surface can be cleaned by the second cleaning module 20.

[0049] On the contrary, when the second end 33 and the fourth end 35 move away from each other, the second cleaning module 20 will gradually approach the first cleaning module 10 under the joint action of the first connecting rod assembly 30 and the second connecting rod assembly 31, that is, the height of the second cleaning module 20 decreases, so that the overall height of the cleaning vehicle is reduced, so as to facilitate the cleaning vehicle to enter or leave the air gap.

[0050] Specifically, the first connecting rod assembly 30 includes a plurality of first connecting rods 36, and the plurality of first connecting rods 36 are spaced and arranged in parallel along the third direction Z on one side of the second cleaning module 20, and one end of all the first connecting rods 36 forms a first end 32, and the other end forms a second end 33. The second connecting rod assembly 31 includes a plurality of second connecting rods 37, and the plurality of second connecting rods 37 are spaced and arranged in parallel along the third direction Z on the other side of the second cleaning module 20, and one end of all the second connecting rods 37 forms a third end 34, and the other end forms a fourth end 35. Among them, the first direction X, the second direction Y, and the third direction Z intersect each other and are not coplanar. Preferably, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In this way, the second cleaning module 20 is driven to rise and fall at the same time by the plurality of first connecting rods 36 and the plurality of second connecting rods 37, so that the movement of the second cleaning module 20 is smoother.

[0051] In some embodiments, the first cleaning module 10 includes a first cleaning seat 11, a sliding seat 12, a guide 13 and a fixed seat 14, and the first cleaning seat 11 and the fixed seat 14 are arranged at intervals along the second direction Y. The two ends of the guide 13 are respectively connected to the first cleaning seat 11 and the fixed seat 14, and the sliding seat 12 is installed on the guide 13 and can move along the extension direction of the guide 13. The guide 13 is extended along the second direction Y, and preferably the guide 13 is tubular. The first cleaning seat 11, the sliding seat 12 and the fixed seat 13 can be a cuboid, and the length direction of the cuboid is the third direction Z, the width direction is the second direction Y, and the height direction is the first direction X. Among them, the second end 33 is hinged to the first cleaning seat 11, and the fourth end 35 is hinged to the sliding seat 12.

[0052] In this way, by moving the sliding seat 12 along the guide member 13 and in the direction close to the first cleaning seat 11, the second end 33 and the fourth end 35 are brought close to each other, thereby prompting the second cleaning module 20 to gradually move away from the first cleaning module 10, that is, the second cleaning module 20 will rise so that the second cleaning module 20 contacts the rotor.

[0053] On the contrary, by moving the sliding seat 12 along the guide member 13 and in a direction away from the first cleaning seat 11, the second end 33 and the fourth end 35 are moved away from each other, thereby causing the second cleaning module 20 to gradually approach the first cleaning module 10, that is, the height of the second cleaning module 20 is lowered, so that the overall height of the cleaning vehicle is reduced, so as to facilitate the cleaning vehicle to be sent into or out of the air gap.

[0054] Specifically in some embodiments, the first cleaning module 10 further includes a driving member 15, which is mounted on the fixed seat 14 and has a telescopic rod 151 that is telescopic relative to the fixed seat 14 along the second direction Y, and the telescopic rod 151 is connected to the sliding seat 12. The driving member 15 is used to drive the telescopic rod 15 to extend and retract, and the telescopic rod 151 of the driving member 15 is extended and retracted relative to the fixed seat 14 to drive the sliding seat 12 to move in the second direction Y, thereby controlling the lifting and lowering of the second cleaning module 20.

[0055] Specifically, by driving the driving member 15 to extend its telescopic rod 151 relative to the fixed seat 14, the telescopic rod 151 can push the sliding seat 12 to move in a direction away from the fixed seat 14, that is, push the sliding seat 12 to move in a direction close to the first cleaning seat 11, so that the second end 33 and the fourth end 35 are close to each other, thereby prompting the second cleaning module 20 to gradually move in a direction away from the first cleaning module 10, that is, the second cleaning module 20 will rise so that the second cleaning module 20 is in contact with the rotor.

[0056] On the contrary, by driving the telescopic rod 151 of the driving member 15 to retract relative to the fixed seat 14, the telescopic rod 151 can drive the sliding seat 12 to move in the direction close to the fixed seat 14, that is, pull the sliding seat 12 to move in the direction away from the first cleaning seat 11, so that the second end 33 and the fourth end 35 are separated from each other, thereby causing the second cleaning module 20 to gradually approach the first cleaning module 10, that is, the height of the second cleaning module 20 is reduced, so that the overall height of the cleaning vehicle is reduced, so as to facilitate the cleaning vehicle to be sent into or leave the air gap.

[0057] Furthermore, in actual use, the driving member 15 usually needs to be connected to an external power source or high-pressure gas by means of wires or air pipes, so as to drive the extension and retraction of the telescopic rod 151 through electric current or high-pressure gas. During the movement of the cleaning vehicle in the air gap, the wires or air pipes may fall off, resulting in power interruption of the driving member 15 and the inability to retract the telescopic rod 151. At this time, the second cleaning module 20 and the first cleaning module 10 of the cleaning vehicle are respectively against the rotor and the stator, and the cleaning vehicle is stuck in the air gap between the stator and the rotor, resulting in the cleaning vehicle being unable to be removed from the air gap normally.

[0058] To this end, in some embodiments, the first cleaning module 10 also includes an elastic member 16, one end of the elastic member 16 is elastically connected to the sliding seat 12, and the other end is elastically connected to the first cleaning seat 11, and the elastic member 16 is used to drive the sliding seat 12 to deform when the sliding seat 12 approaches the first cleaning seat 11, and accumulate elastic force for moving the sliding seat 12 away from the first cleaning seat 11.

[0059] In this way, when the second cleaning module 20 is against the rotor surface, if there is a problem of power interruption of the driving member 15, the driving member 15 cannot continue to push the sliding seat 12, and the sliding seat 12 will gradually move in the direction away from the first cleaning seat 11 under the action of the elastic force of the elastic member 16, so that the second cleaning module 20 gradually approaches the first cleaning module 10 and finally separates from the rotor surface, so that the overall height of the cleaning vehicle is reduced. At this time, the cleaning vehicle can be safely and conveniently taken out of the air gap.

[0060] Furthermore, when the driving member 15 normally drives the telescopic rod 151 to extend and retract to drive the sliding seat 12 to move, the elastic member 12 can be used to cooperate with the extension and retraction of the telescopic rod 151 to accelerate the movement of the sliding seat 12, that is, the sliding seat 12 is driven to move by the elastic member 12 and the telescopic rod 151 at the same time, so that the second cleaning module 20 can quickly approach or move away from the first cleaning module 10.

[0061] It is understandable that in some other embodiments, the elastic member 16 can also connect the sliding seat 12 and the fixed seat 14. The sliding seat 12 can also drive the elastic member 16 to deform while moving closer to the first cleaning seat 11, and accumulate elastic force for moving the sliding seat 12 away from the first cleaning seat 11.

[0062] Specifically in some embodiments, the guide members 13 include two, the two guide members 13 are arranged at intervals along the third direction Z, the sliding seat 12 is slidably mounted on the two guide members 13, and the second cleaning module 20 is arranged between the two guide members 13. The two guide members 13 simultaneously guide the sliding seat 12, so that the movement of the sliding seat 12 is smoother. Among them, the first direction X, the second direction Y, and the third direction Z intersect each other and are not coplanar.

[0063] Furthermore, the elastic member 16 also includes two elastic members 16, and the elastic members 16 are springs. The two springs are respectively mounted on the two guide members 13. When the power of the driving member 15 is interrupted, the two springs can simultaneously drive the sliding seat 12 to move to ensure that the second cleaning module 20 can be completely separated from the rotor surface.

[0064] Specifically in some embodiments, in order to achieve the cleaning of the stator surface by the first cleaning module 10, a first suction port 111 and a first suction pipe interface 112 connected to the first suction port 111 are provided on the first cleaning seat 11, and the first suction pipe interface 112 is connected to an external negative pressure device through a suction pipe to generate negative pressure at the first suction port 111. Preferably, the first suction port 111 is a bar-shaped hole and extends along the third direction Z. In this way, when the first cleaning module 10 is adsorbed on the stator surface, the first suction port 111 faces the stator surface, so that the dust and foreign matter on the stator surface are adsorbed by the negative pressure generated by the first suction port 111, thereby completing the cleaning of the stator surface.

[0065] Furthermore, in order to clean the rotor surface through the second cleaning module 20, a second suction port 21 and a second suction pipe interface 22 connected to the second suction port 21 are provided on the second cleaning module 20, and the second suction pipe interface 22 is connected to an external negative pressure device through a suction pipe to generate negative pressure at the second suction port 21. Preferably, the second suction port 21 is a bar-shaped hole and extends along the third direction Z. In this way, when the second cleaning module 20 abuts against the rotor surface, the second suction port 21 faces the rotor surface, and the negative pressure generated by the second suction port 21 adsorbs dust and foreign matter on the rotor surface, thereby completing the cleaning of the rotor surface.

[0066] Specifically, taking the state when the second cleaning module 20 is raised away from the first cleaning module 10 as a reference, the first dust suction port 111 is arranged on the side of the first cleaning module 10 in the first direction X that is farther away from the second cleaning module 20, and the first suction pipe interface 112 is arranged on the side of the first cleaning seat 11 facing the sliding seat 12. At the same time, an avoidance groove 24 for avoiding the suction pipe is arranged on the side of the second cleaning module 20 facing the first cleaning module 10, and avoidance holes 18 for the suction pipe to pass through are arranged on the sliding seat 12 and the fixed seat 14, so that the suction pipe can pass through the fixed seat 14 and the sliding seat 12 to be connected with the first suction pipe interface 112 and the second suction pipe interface 22. And because the avoidance groove 24 is arranged at the bottom of the second cleaning module 20, after the height of the second cleaning module 20 is lowered, the suction pipe will enter the avoidance groove 24 and will not interfere with the second cleaning module 20.

[0067] The length of the first dust suction port 111 and the second dust suction port 21 is the width of the slot wedge of the stator or rotor, so that the cleaning vehicle can move along the longitudinal direction of one of the slot wedges and clean the slot wedge at the same time. Optionally, the length of the first dust suction port 111 and the second dust suction port 21 ranges from 140mm to 180mm. In actual use, the cleaning vehicle is driven by an external drive device, and the interval between each slot change is 140mm, and the length of the first dust suction port 111 and the second dust suction port 21 is preferably 180mm, so that after the cleaning vehicle changes the slot, the first dust suction port 111 and the second dust suction port 21 are still partially located at the position of the previous slot wedge, so that the suction range of the first dust suction port 111 and the second dust suction port 21 can overlap and cover the same position, achieving the effect of multiple cleanings.

[0068] Specifically, in some embodiments, in order to monitor the cleaning effect of the stator surface and the rotor surface, the cleaning vehicle further includes an image acquisition component, which is used to acquire an image of the surface of the stator (i.e., the first part to be cleaned), so that the staff can view the condition of the stator surface in real time, and then select the place that needs to be cleaned according to the condition of the stator surface and move the cleaning vehicle to clean it. In addition, the final cleaning effect of the stator surface can also be viewed by coordinating the movement of the cleaning vehicle in the gap.

[0069] Specifically, the image acquisition component is disposed on a side of the first cleaning module 10 where the first suction port 111 is disposed, and the image acquisition component is disposed adjacent to the first suction port 111, so that the area photographed by the image acquisition component is substantially the same as the area cleaned by the first suction port 111. In this way, the staff can view the dust collection situation of the stator surface in the dust collection area of ​​the first suction port 111 in real time through the image acquisition component.

[0070] It is understandable that the image acquisition component can be, but is not limited to, disposed on the first cleaning module 10, and can also be disposed on one of the sliding seat 12, the guide 13 or the fixed seat 14, as long as the image acquisition component can capture the image of the stator surface.

[0071] Furthermore, the image acquisition component can also acquire images of the surface of the rotor (i.e., the second part to be cleaned) so that the staff can view the situation of the rotor surface in real time. For details, please refer to the above-mentioned process of acquiring the stator surface image, which will not be repeated here. Preferably, the image acquisition component includes two image acquisition modules, one of which is arranged on the side of the first cleaning module 10 provided with the first suction port 111, and the image acquisition component is arranged adjacent to the first suction port 111, and the other image acquisition module is arranged on the side of the second cleaning module 20 provided with the second suction port 21, and the image acquisition component is arranged adjacent to the second suction port 21.

[0072] In some embodiments of the present application, in order to reduce the friction when the cleaning vehicle moves on the stator surface or the rotor surface, a first walking member 17 is provided on the first cleaning module 10. The first walking member 17 is located on the side of the first cleaning module 10 where the first dust suction port 111 is provided. When the first cleaning module 10 is adsorbed on the rotor surface, the first cleaning module 10 can move along the rotor surface through the first walking member 17 to avoid direct contact between the first cleaning module 10 and the stator surface. Excessive friction affects the movement of the cleaning vehicle in the air gap.

[0073] Furthermore, a second walking member 23 is provided on the second cleaning module 20, and the second walking member 23 is located on a side of the second cleaning module 20 where the second dust suction port 21 is provided. When the second cleaning module 20 abuts against the rotor surface, the second cleaning module 20 can move along the rotor surface through the second walking member 23, so as to avoid direct contact between the second cleaning module 20 and the rotor surface through the second walking member 23, and excessive friction will affect the movement of the cleaning vehicle in the air gap.

[0074] Specifically, the first walking member 17 is a plurality of pulleys arranged on the first cleaning seat 11 and the sliding seat 12, and the second walking member 23 is a plurality of pulleys arranged on the second cleaning module 20. In some other embodiments, the first walking member 17 and the second walking member 23 can also be tracks.

[0075] In actual use, the movement of the cleaning vehicle in the air gap can be achieved by driving the first walking member 17 and the second walking member 23 to move, or by connecting the cleaning vehicle to a driving device located outside the air gap and driving the cleaning vehicle to move in the air gap through the driving device.

[0076] Specifically, in some embodiments of the present application, an engine cleaning device is provided, and the engine cleaning device includes the above-mentioned cleaning vehicle. The specific structure of the cleaning vehicle refers to the above-mentioned embodiments. Since the engine cleaning device adopts all the technical solutions of all the above-mentioned embodiments, and has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, they will not be described one by one here.

[0077] Specifically, the engine cleaning equipment also includes a traction rope, which is connected to a cleaning vehicle to drive the cleaning vehicle to move along the longitudinal direction of the traction rope. In this way, during the cleaning operation of the generator through the engine cleaning equipment, the traction rope is passed through the gap so that the cleaning vehicle can be indirectly driven to move by pulling the traction rope, thereby achieving the purpose of indirectly driving the cleaning vehicle to move axially or circumferentially along the rotor or stator.

[0078] Furthermore, the engine cleaning device also includes a winding device for driving the traction rope to be wound up, and when the winding device winds up the traction rope, the traction rope will drive the cleaning vehicle to move. The winding device can be arranged outside the engine, so as to drive the cleaning vehicle to move outside the engine, and thus there is no need to arrange power components on the cleaning vehicle itself, thus streamlining the structure of the cleaning vehicle and facilitating the miniaturization and lightweight design of the cleaning vehicle.

[0079] In order to prevent the movement of the cleaning vehicle in the air gap from deviating from the established route, the generator cleaning equipment also includes a guide rope. A guide hole 40 is opened on the cleaning vehicle, and the guide rope is passed through the guide hole 40. In this way, during the cleaning operation of the generator by the engine cleaning equipment, the movement of the cleaning vehicle is guided by the guide rope passed through the air gap, which can greatly reduce the risk of the cleaning vehicle running off the track during the cleaning process.

[0080] The above generator cleaning vehicle has at least the following advantages:

[0081] The cleaning vehicle has the functions of cleaning the stator surface and ventilation holes, cleaning the rotor surface and ventilation holes, and inspecting them.

[0082] The second cleaning module 20 of the cleaning vehicle is height-adjustable compared to the first cleaning module 10 .

[0083] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
