Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning units, and in particular to a spray device for an air-conditioning unit. Background Art

[0002] Air conditioning units use refrigerant to exchange heat, and the refrigerant's conversion efficiency during operation is crucial to the unit's heat exchange efficiency. To effectively improve the condenser's condensing efficiency, many large air conditioning units are equipped with spray cooling devices. These devices continuously spray coolant onto the condenser's surface during operation, achieving a cooling effect that effectively improves the condenser's condensing efficiency.

[0003] For example, a Chinese patent document with the publication number CN212777709U discloses an air-conditioning unit with a spray cooling system, including a refrigerant circulation system, the refrigerant circulation system including a condenser, the spray cooling system including an infusion pipeline and a spray component connected to the infusion pipeline, the spray component being provided with a liquid accumulation chamber and a plurality of spray holes connected to the liquid accumulation chamber, the infusion pipeline being capable of conveying cooling liquid into the liquid accumulation chamber, the spray holes being a through-hole structure with a middle portion tightened and two ends expanded, so that the cooling liquid in the liquid accumulation chamber can be accelerated to spray onto the surface of the condenser through the spray holes. By providing the liquid accumulation chamber, the water pressure in the spray component is increased, so as to effectively increase the spray speed of the cooling liquid; on the other hand, the patent document further increases the spray speed of the cooling liquid by providing the spray holes as a through-hole structure with a middle portion tightened and two ends expanded.

[0004] In the above-mentioned related technologies, the condenser can be cooled through the infusion pipeline and the spray hole, but the water used for spray cooling is usually industrial water, which contains more impurities. After spraying for a long time, the impurities will accumulate in the spray head and the spray pipe, causing blockage, which in turn affects the normal spraying and causes uneven spraying. Uneven spraying will lead to local water mist loss and a 10%-30% decrease in heat exchange efficiency. Then the staff needs to clean the spray pipe and the spray head regularly. When cleaning the impurities, the air-conditioning unit cannot be cooled, which can easily cause the air-conditioning unit to malfunction. Summary of the Invention

[0005] The present application provides a spray device for an air-conditioning unit, which aims to solve the problem in the related art that the air-conditioning unit cannot be cooled when impurities in the spray pipe and the spray head are cleaned.

[0006] The present application provides an air conditioning unit spray device that adopts the following technical solution:

[0007] A spray device for an air-conditioning unit comprises a main pipeline, above which are arranged a plurality of spray assemblies for spraying and cooling the air-conditioning unit, the spray assemblies comprising a mounting base fixed to the main pipeline, a rotating plate rotatably connected to the mounting base, and a first spray pipe and a second spray pipe arranged on the mounting base, the first spray pipe and the second spray pipe are both provided with a plurality of nozzles, the rotating plate is provided with a connecting groove, one end of the connecting groove is connected to the main pipeline, and the other end is used to connect to the first spray pipe or the second spray pipe, and the main pipeline is provided with a driving assembly for driving the rotating plate to rotate.

[0008] By adopting the above technical solution, when the air-conditioning unit is sprayed for cooling, water is passed into the main pipe through the water pump, and the water passed into the main pipe will enter the connecting groove, and then the water in the connecting groove enters the first spray pipe or the second spray pipe. When the water in the connecting groove enters the first spray pipe, the opening of the connecting groove and the second spray pipe do not correspond, and the water in the connecting groove cannot enter the second spray pipe. The air-conditioning unit is cooled by the nozzle on the first spray pipe. When the first spray pipe has been used for a period of time and the nozzle on the first spray pipe sprays water unevenly, the inner wall and nozzle of the first spray pipe need to be cleaned. At this time, the driving assembly drives the rotating plate to rotate, so that the opening of the connecting groove on the rotating plate corresponds to the end opening of the second spray pipe. At the same time, the rotating plate blocks the end opening on the first spray pipe, and the water in the connecting groove enters the second spray pipe. The water is sprayed through the nozzle on the second spray pipe to cool the air-conditioning unit. When the second spray pipe cools the air-conditioning unit, the staff can clean the first spray pipe and the nozzle on the first spray pipe. Through the alternating operation of the first spray pipe and the second spray pipe, it can be achieved that when cleaning impurities, the spraying of the corresponding air-conditioning unit will not be affected, thereby reducing the failure of the air-conditioning unit.

[0009] Optionally, a cleaning plate is slidably connected to the first spray pipe and the second spray pipe. When the first spray pipe and the connecting groove are connected to spray the air-conditioning unit, the cleaning plate in the first spray pipe is at the highest point, and the cleaning plate in the second spray pipe is at the lowest point. The rotating plate is provided with a drainage channel for connecting with the end opening of the first spray pipe or the end opening of the second spray pipe. The drainage channel is provided with an opening for connecting with the outside world. When the connecting groove corresponds to the end opening of the first spray pipe, the drainage channel corresponds to the end opening of the second spray pipe.

[0010] By adopting the above technical solution, when spraying the air-conditioning unit, the water in the main pipeline enters the first spray pipe through the connecting groove, and then cools the air-conditioning unit through the nozzle on the first spray pipe. At the same time, the cleaning plate in the first spray pipe is at the highest point, and the cleaning plate in the second spray pipe is at the lowest point. After the first spray pipe has been used for a period of time, when the first spray pipe and the nozzle on the first spray pipe need to be cleaned, the driving component drives the rotating plate to rotate so that the second spray pipe and the connecting groove correspond. Then, the water in the main pipeline enters the second spray pipe through the connecting groove, pushing the water in the second spray pipe to clean. The cleaning plate moves from the lowest point to the highest point, and at the same time, the opening of the first spray pipe is connected to the drainage channel, and the remaining water in the first spray pipe is discharged through the drainage channel. At the same time, the cleaning plate in the first spray pipe moves from the highest point to the lowest point of the first spray pipe under the action of gravity. During the movement, the inner wall of the first spray pipe can be scraped off, and then the impurities on the inner wall of the first spray pipe are pushed downward, and finally discharged from the first spray pipe through the drainage channel, thereby facilitating the cleaning of impurities on the inner wall of the first spray pipe. When the second spray pipe needs to be cleaned, the working principle is the same as that of cleaning the first spray pipe.

[0011] Optionally, a connecting pipe is provided on the mounting seat, and the connecting pipe is used to connect the first spray pipe and the second spray pipe. The first spray pipe and the second spray pipe are both rotatably connected to the connecting pipe, and a pushing block for pushing the cleaning plate downward is slidably connected in the connecting pipe.

[0012] By adopting the above technical solution, since a pushing block is provided in the connecting pipe, during the downward movement of the cleaning plate, the pushing block will push the cleaning plate to move, and then the cleaning plate can move downward more smoothly. At the same time, when water is passed into the first spray pipe or the second spray pipe, the water pressure can push the cleaning plate and the pushing block above the cleaning plate to move upward at the same time, and finally the cleaning plate is at the highest point, and then the pushing block is in the connecting pipe; in addition, under the action of the connecting pipe and the support bar, the first spray pipe and the second spray pipe can be more stable when rotating.

[0013] Optionally, the first spray pipe and the second spray pipe are both provided with connecting holes corresponding to the nozzles, and the first spray pipe and the second spray pipe are both provided with sealing components for sealing the connecting holes; the sealing components include a sealing spring fixed in the nozzle and a sealing plate fixed on the sealing spring, and the sealing plate is spaced apart from the side of the sealing spring and the inner wall of the first spray pipe. When the side of the sealing plate facing away from the sealing spring abuts against the side of the cleaning plate, the side of the sealing plate facing away from the sealing spring is on the same plane as the inner wall of the first spray pipe, and at this time the connecting hole is blocked.

[0014] By adopting the above technical solution, in the initial state, the sealing spring supports the sealing plate so that the sealing plate is spaced apart from the side close to the sealing spring and the inner wall of the first spray pipe. Then, water can enter the nozzle through the gap between the sealing plate and the first spray pipe. In the process of the cleaning plate moving up and down, the cleaning plate pushes the sealing plate to move into the nozzle and then seals the opening of the connecting hole. At this time, the scraped impurities can be reduced from entering the nozzle through the connecting port. When the cleaning plate and the sealing plate are misaligned, the sealing spring pushes the sealing plate to move in the opposite direction, leaving a gap between the sealing plate and the first spray pipe, so that the water in the subsequent first spray pipe can enter the nozzle.

[0015] Optionally, a support bar is provided on the mounting seat, and a sponge bar for cleaning the outer end of the nozzle is provided on the support bar. The connecting pipe is fixed to the mounting seat through the support bar, and the sponge bar is provided between the first spray pipe and the second spray pipe, and a control component for driving the first spray pipe and the second spray pipe to rotate is provided on the rotating plate.

[0016] By adopting the above technical solution, while the rotating plate rotates, the first spray pipe and the second spray pipe rotate under the action of the control component. During the rotation, the nozzle will abut against the sponge strip, and the impurities on the surface of the nozzle will be cleaned through the sponge strip.

[0017] Optionally, the drive assembly includes a driving gear rotatably connected to the main pipe, a driven gear fixed on a rotating plate, and a toothed belt wound around the driving gear and the driven gear. A plurality of driven gears are provided, and the plurality of driven gears correspond one-to-one to the plurality of rotating plates, and the toothed belt is meshed with the plurality of driven gears.

[0018] By adopting the above technical solution, the driving gear will drive the toothed belt to rotate during its rotation. Since the toothed belt and the driven gear are engaged, the toothed belt drives multiple driven gears to rotate, thereby realizing the adjustment of the rotating plate position.

[0019] Optionally, the control assembly includes a control gear ring fixed on the rotating plate and a control gear fixed on the first spray pipe, and a control gear is also fixedly mounted on the second spray pipe, and the control gear ring and the two control gears are engaged simultaneously.

[0020] By adopting the above technical solution, the rotating plate will drive the control ring gear to rotate during rotation, and the control ring gear will drive the control gear to rotate during rotation, and then the control gear will drive the first spray pipe and the second spray pipe to rotate.

[0021] Optionally, a drain pipe is provided on the mounting seat, and the drain pipe is used to communicate with the opening of the drainage channel.

[0022] By adopting the above technical solution, the water in the drainage channel is discharged through the drainage pipe, and then the cleaning plate moves downward under the action of gravity.

[0023] Optionally, the blocking plate is provided with a pushing surface for abutting against the cleaning plate, the pushing surface is arranged at an angle, and two pushing surfaces are provided on each blocking plate.

[0024] By adopting the above technical solution, under the action of the pushing surface, the blocking plate can be easily pushed to move into the nozzle during the movement of the cleaning plate.

[0025] Optionally, the pushing block is configured as a spherical structure.

[0026] By adopting the above technical solution, since the pushing block is set to a spherical structure, when the cleaning plate pushes the pushing block to move, the friction between the pushing block and the inner wall of the first spray pipe can be reduced.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It is necessary to clean the inner wall and the nozzle of the first spray pipe. At this time, the driving assembly drives the rotating plate to rotate so that the opening of the connecting groove on the rotating plate corresponds to the end opening of the second spray pipe. At the same time, the rotating plate blocks the end opening on the first spray pipe, and the water in the connecting groove enters the second spray pipe. The water is sprayed through the nozzle on the second spray pipe to cool the air-conditioning unit. When the second spray pipe cools the air-conditioning unit, the staff can clean the first spray pipe and the nozzle on the first spray pipe.

[0029] 2. Under the action of gravity, the cleaning plate in the first spray pipe moves from the highest point to the lowest point of the first spray pipe. During the movement, the inner wall of the first spray pipe can be scraped off, and then the impurities on the inner wall of the first spray pipe are pushed downward, and finally discharged from the first spray pipe through the drainage channel, thereby facilitating the cleaning of impurities on the inner wall of the first spray pipe.

DETAILED DESCRIPTION

[0039] The following combination Figures 1-8 This application is described in further detail.

[0040] The embodiment of the present application discloses a spray device for an air conditioning unit. Figure 1 A spray device for an air-conditioning unit includes a main pipe 01 arranged on the air-conditioning unit, and a spray component 1 for cooling the air-conditioning unit is arranged on the main pipe 01. Water in the main pipe 01 enters the spray component 1, and water is sprayed through the spray component 1 to cool the outdoor unit of the air-conditioning unit.

[0041] Reference Figure 1 and Figure 2 The spray assembly 1 includes a mounting base 11 fixed on the main pipeline 01, a first spray pipe 12 and a second spray pipe 13 arranged on the mounting base 11, and a rotating plate 14 rotatably connected to the mounting base 11. A plurality of nozzles are provided on the first spray pipe 12 and the second spray pipe 13. A connecting groove 2 is provided on the rotating plate 14. One end of the connecting groove 2 is used to communicate with the first spray pipe 12 or the second spray pipe 13, and the other end is used to communicate with the main pipeline 01. At the same time, a driving assembly 3 for driving the rotating plate 14 to rotate is provided on the main pipeline 01. When the driving assembly 3 drives the rotating plate 14 to rotate, the position of the connecting channel on the rotating plate 14 can be adjusted so that the end of the connecting groove 2 away from the main pipeline 01 is connected with the lower end opening of the first spray pipe 12 or the second spray pipe 13.

[0042] Reference Figures 1 to 3 The connecting groove 2 includes a first vertical portion 21, a connecting portion 22 and a second vertical portion 23. The first vertical portion 21 and the rotating plate 14 are coaxially arranged, and the second vertical portion 23 and the rotating plate 14 are non-coaxially arranged, and the connecting portion 22 is used to connect the first vertical portion 21 and the second vertical portion 23. During the rotation of the rotating plate 14, the first vertical portion 21 is always connected to the main pipe 01, and the second vertical portion 23 will rotate. When the second vertical portion 23 corresponds to the end opening of the first spray pipe 12, the water in the main pipe 01 enters the first spray pipe 12 through the first vertical portion 21, the connecting portion 22 and the second vertical portion 23. At this time, the end opening of the first spray pipe 12 will be blocked, and the air-conditioning unit can only be cooled by spraying water through the nozzle on the first spray pipe 12.

[0043] After multiple first spray pipes 12 and the nozzles on the first spray pipes 12 have been used for a period of time, when it is necessary to clean impurities in the nozzles and the first spray pipes 12, the driving assembly 3 drives the rotating plate 14 to rotate, and then the second vertical portion 23 corresponds to the end opening of the second spray pipe 13, and the second vertical portion 23 does not correspond to the end opening of the first spray pipe 12. The water in the main pipeline 01 enters the second spray pipe 13 through the first vertical portion 21, the connecting portion 22 and the second vertical portion 23, and the air-conditioning unit is sprayed with water to cool it down through the nozzles on the second spray pipe 13. At this time, the impurities in the first spray pipe 12 can be cleaned.

[0044] Reference Figures 1 to 3 A cleaning plate 02 is provided in the first spray pipe 12 and the second spray pipe 13. The cleaning plate 02 is slidably connected to the inner wall of the first spray pipe 12 along the length direction of the first spray pipe 12. In this embodiment, the cleaning plate 02 in the first spray pipe 12 and the cleaning plate 02 in the second spray pipe 13 are positioned at different heights. When the air-conditioning unit is cooled by the first spray pipe 12, the water in the main pipe 01 will enter the first spray pipe 12. At this time, the cleaning plate 02 in the first spray pipe 12 is at the highest point, and the second spray pipe 13 is not connected to the main pipe 01. There is no water in the second spray pipe 13, and the cleaning plate 02 in the second spray pipe 13 is at the lowest point under the action of gravity.

[0045] Reference Figures 2 to 4A drainage channel 4 is provided on the rotating plate 14. Both ends of the drainage channel 4 are provided with openings, and one end of the drainage channel 4 is used to communicate with the lower end opening of the first spray pipe 12 or the second spray pipe 13. When the communicating groove 2 is connected with the first spray pipe 12, the opening of the drainage channel 4 is connected with the second spray pipe 13, and the water in the second spray pipe 13 will enter the drainage channel 4 under the action of gravity. When the communicating groove 2 is connected with the second spray pipe 13, the opening of the drainage channel 4 is connected with the first spray pipe 12, and the water in the first spray pipe 12 will enter the drainage channel 4 under the action of gravity.

[0046] Reference Figures 2 to 4 A connecting channel 41 is provided on the mounting base 11, and a drain pipe 42 for communicating with the connecting channel 41 is provided on the mounting base 11. The connecting channel 41 is connected to the drainage channel 4. In this embodiment, the drainage channel 4 and the connecting channel 41 are arranged in an annular structure, and an opening for communicating with the connecting channel 41 is provided on the drainage channel 4. During the rotation of the rotating plate 14, the drainage channel 4 and the connecting channel 41 are always in a connected state.

[0047] When it is necessary to clean the impurities in the first spray pipe 12, the driving assembly 3 drives the rotating plate 14 to rotate, so that the second spray pipe 13 is connected to the main pipe 01, and the first spray pipe 12 is connected to the drainage channel 4. The water in the main pipe 01 enters the second spray pipe 13 through the first vertical portion 21, the connecting portion 22 and the second vertical portion 23. At this time, under the action of water pressure, the cleaning plate 02 in the second spray pipe 13 will be pushed upward. At the same time, the water in the first spray pipe 12 will enter the drainage channel 4 under the action of gravity, and then be discharged through the drainage channel 4. The cleaning plate 02 in the first spray pipe 12 will move downward under the action of gravity. During the downward movement, the inner wall of the first spray pipe 12 will be scraped off. At this time, the purpose of cleaning the inner wall of the first spray pipe 12 is achieved. When cleaning the impurities in the first spray pipe 12, the air-conditioning unit can still be cooled through the second spray pipe 13, thereby achieving the purpose of cleaning impurities while continuing to cool the air-conditioning unit, thereby reducing damage to the air-conditioning unit. When the cleaning plate 02 moves downward, the scraped impurities will be driven to move downward. At this time, the scraped impurities will fall into the drainage channel 4 and be discharged from the first spray pipe 12 through the drainage channel 4.

[0048] When it is necessary to clean the impurities in the second spray pipe 13, the driving assembly 3 drives the rotating plate 14 to rotate, so that the first spray pipe 12 is connected to the connecting groove 2, and the second spray pipe 13 is connected to the drainage channel 4. The water in the main pipeline 01 enters the first spray pipe 12 through the first vertical portion 21, the connecting portion 22 and the second vertical portion 23. At this time, under the action of water pressure, the cleaning plate 02 in the first spray pipe 12 will be pushed upward. At the same time, the water in the second spray pipe 13 will enter the drainage channel 4 under the action of gravity, and then be discharged through the drainage channel 4. The cleaning plate 02 in the second spray pipe 13 will move downward under the action of gravity. During the downward movement, the inner wall of the second spray pipe 13 is scraped, and the purpose of cleaning the inner wall of the second spray pipe 13 is achieved. When cleaning the impurities in the second spray pipe 13, the air-conditioning unit can still be cooled through the first spray pipe 12, thereby achieving the purpose of cleaning impurities while continuing to cool the air-conditioning unit, thereby reducing damage to the air-conditioning unit. When the cleaning plate 02 moves downward, the scraped impurities will be driven to move downward. At this time, the scraped impurities will fall into the drainage channel 4 and be discharged from the second spray pipe 13 through the drainage channel 4.

[0049] Reference Figures 2 to 4 A support bar (not shown) is provided on the mounting base 11, on which a connecting pipe 44 is fixedly mounted. The connecting pipe 44 is used to connect the first spray pipe 12 and the second spray pipe 13. At the same time, the first spray pipe 12 and the second spray pipe 13 are both rotatably connected to the connecting pipe 44. A push block 05 is provided on the cleaning plate 02 inside the first spray pipe 12 and the second spray pipe 13. When one of the cleaning plates 02 moves upward, it pushes the push block 05 upward. Under the action of gravity, the push block 05 is further pushed downward, making it more convenient to clean the inner wall of the first spray pipe 12 or the inner wall of the second spray pipe 13. In addition, the action of the connecting pipe 44 and the support bar can make the first spray pipe 12 and the second spray pipe 13 more stable when rotating.

[0050] Reference Figures 2 to 4 The connecting pipe 44 includes two bent portions 441 and a horizontal portion 442. The two bent portions 441 and the horizontal portion 442 are integrally formed. The openings of the two bent portions 441 are set downward, and the first spray pipe 12 and the second spray pipe 13 are respectively rotatably connected to the bent portions 441; at the same time, the pushing block 05 is set to a pushing ball, the diameter of the pushing ball is smaller than the diameter of the first spray pipe 12, and the diameter of the first spray pipe 12 is the same as the diameter of the second spray pipe 13.

[0051] In this embodiment, the cleaning plate 02 in the first spray pipe 12 is in the highest position, and the cleaning plate 02 in the second spray pipe 13 is in the lowest position. When the second spray pipe 13 is needed to spray and cool the air-conditioning unit, the water in the main pipe 01 enters the second spray pipe 13 through the connecting groove 2. At this time, the cleaning plate 02 in the second spray pipe 13 and the pushing ball above the cleaning plate 02 will move upward under the action of water pressure, and the cleaning plate 02 in the first spray pipe 12 and the pushing ball above the cleaning plate 02 will move downward under the action of gravity. In other embodiments, multiple pushing balls can be set above the cleaning plate 02, and then the effect of pushing the cleaning plate 02 downward can be better. Since the pushing block 05 is set to a spherical structure, the friction between the pushing block 05 and the first spray pipe 12 or the second spray pipe 13 can be reduced during the up and down movement of the cleaning plate 02.

[0052] Reference Figure 2 、 Figures 5 to 7 A connecting hole 04 is provided on the first spray pipe 12 and the second spray pipe 13. The connecting hole 04 is connected to the nozzle. Then the water in the first spray pipe 12 and the second spray pipe 13 enters the nozzle through the connecting hole 04 and is finally sprayed out through the nozzle. At the same time, a blocking component 5 is provided in the nozzle. The blocking component 5 is used to block the connecting hole 04. When the cleaning plate 02 moves downward, it can reduce impurities from entering the nozzle through the connecting hole 04.

[0053] Reference Figure 2 、 Figures 5 to 7 The blocking assembly 5 includes a blocking spring 51 fixed in the nozzle and a blocking plate 52 fixed on the blocking spring 51. The blocking plate 52 is slidably connected in the nozzle. The side of the blocking plate 52 away from the blocking spring 51 is set as an arc surface. Under the action of the blocking spring 51, the arc surface of the blocking plate 52 away from the blocking spring 51 protrudes from the inner wall of the first spray pipe 12. At this time, the side of the blocking plate 52 in contact with the blocking spring 51 is spaced from the inner wall of the first spray pipe 12, and then a water inlet channel 7 is formed, which can allow the water in the first spray pipe 12 to pass through The water inlet channel 7 enters the nozzle, and during the downward movement of the cleaning plate 02, the blocking plate 52 will be pushed to move into the nozzle. At this time, the blocking spring 51 is compressed. When the cleaning plate 02 and the blocking plate 52 are in complete contact, the arc-shaped surface of the blocking plate 52 facing away from the blocking spring 51 and the inner wall of the first spray pipe 12 are on the same plane. The water inlet channel 7 formed between the side of the blocking plate 52 close to the blocking spring 51 and the inner wall of the first spray pipe 12 disappears. By setting the blocking plate 52, the cleaning plate 02 can be reduced from pushing impurities into the connecting hole 04.

[0054] Reference Figure 2 、 Figures 5 to 7, a pushing surface 53 is provided on the blocking plate 52, and the pushing surface 53 is inclined. The pushing surface 53 is used to abut against the cleaning plate 02. Two pushing surfaces 53 are provided on each blocking plate 52. In the process of the cleaning plate 02 moving up and down, both can abut against the pushing surface 53, and then the cleaning plate 02 can push the blocking plate 52 to move. When the cleaning plate 02 and the blocking plate 52 are not in contact, under the action of the blocking spring 51, the blocking plate 52 can be pushed to reset, and then the side of the blocking plate 52 in contact with the blocking spring 51 forms a water inlet channel 7 with the inner wall of the first spray pipe 12 to continue to pass water. At the same time, the impurities scraped off during the downward movement of the cleaning plate 02 will enter the drainage channel 4, and then be discharged through the drainage pipe 42, thereby achieving the purpose of cleaning impurities.

[0055] Reference Figure 2 、 Figures 5 to 7 A sponge strip 03 is provided on the support strip, and a control component 6 is provided on the rotating plate 14. The control component 6 is used to drive the first spray pipe 12 and the second spray pipe 13 to rotate. During the rotation of the first spray pipe 12 and the second spray pipe 13, the end of the nozzle will abut against the sponge strip 03, and the sponge strip 03 can be used to clean impurities on the surface of the nozzle.

[0056] Reference Figure 2 、 Figure 3 and Figure 8 The control component 6 includes a control ring gear 61 fixed on the rotating plate 14 and a control gear 62 fixed on the first spray pipe 12. The second spray pipe 13 is also provided with a control gear 62. The two control gears 62 are engaged with the control ring gear 61 at the same time. When the driving component 3 drives the rotating plate 14 to rotate, the rotating plate 14 and the control ring gear 61 rotate at the same time, and the control ring gear 61 will drive the first spray pipe 12 and the second spray pipe 13 to rotate at the same time.

[0057] Reference Figure 2 、 Figure 3 and Figure 8 The driving assembly 3 includes a driving gear 31 rotatably connected to the main pipe 01, a driven gear 32 fixed on the rotating plate 14, and a toothed belt 33 wound around the driving gear 31 and the driven gear 32. A plurality of driven gears 32 are provided, and the plurality of driven gears 32 correspond to the plurality of rotating plates 14 one by one, and the toothed belt 33 is engaged with the plurality of driven gears 32. A driving motor is provided on the main pipe 01, and the output shaft of the driving motor is fixedly connected to the driving gear 31. When the rotating plate 14 needs to rotate, the driving motor works, and the driving motor drives the driving gear 31 to rotate, and the driving gear 31 drives the toothed belt 33 to rotate, and the toothed belt 33 drives the plurality of driven gears 32 to rotate, thereby achieving the purpose of adjusting the positions of the plurality of rotating plates 14.

[0058] The implementation principle of the spray device of an air-conditioning unit in the embodiment of the present application is as follows: the water in the main pipeline 01 enters the connecting groove 2, and enters the first spray pipe 12 through the connecting groove 2. At this time, the second spray pipe 13 is connected to the opening of the drainage channel 4, and the water in the first spray pipe 12 enters the nozzle through the connecting hole 04. The nozzle sprays water to cool the air-conditioning unit. After the first spray pipe 12 has been used for a period of time, it is necessary to clean the impurities in the first spray pipe 12, and then the driving component 3 drives the rotating plate 14 to rotate, so that the connecting groove 2 on the rotating plate 14 is connected to the second spray pipe 13. The water in the main pipeline 01 enters the second spray pipe 13 through the connecting groove 2, and the first spray pipe 12 It is connected to the drainage channel 4, and the water entering the second spray pipe 13 will push the cleaning plate 02 to move from the lowest point to the highest point. The water in the first spray pipe 12 enters the drainage channel 4 under the action of gravity. At the same time, the cleaning plate 02 in the first spray pipe 12 moves downward under the action of gravity. During the downward movement of the cleaning plate 02, the impurities on the inner wall of the first spray pipe 12 are cleaned. At this time, the impurities on the inner wall of the first spray pipe 12 are scraped off, and the scraped impurities enter the drainage channel 4 under the action of gravity, and then are discharged through the drainage channel 4, thereby achieving the purpose of cleaning the impurities on the inner wall of the first spray pipe 12. While cleaning the impurities, the second spray pipe 13 can still spray the air-conditioning unit.
