[0002] The automobile air cylinder, also known as an air tank or compressed air storage tank, plays a vital role in the vehicle's braking system; it is mainly used to store the compressed air generated by the air compressor.

[0003] In the prior art, during the air compression process, the moisture in the air will be compressed into liquid water, and at the same time, tiny oil droplets in the air will be brought into the air cylinder; as time goes by, these moisture and oil will accumulate to the bottom of the air cylinder under the influence of gravity. Therefore, a drain valve structure is mostly provided at the bottom of the automobile air cylinder to clean the moisture and oil in the automobile air cylinder.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1-11 As shown, a vehicle air cylinder cleaning device, such as Figure 1-3 As shown, it includes a cleaning mechanism 5 for cleaning the compressed air led out through the air outlet pipe 3 in the cylinder 1. The cleaning mechanism 5 is arranged between the cylinder 1 and the air outlet pipe 3. The air outlet pipe 3 is arranged on the cylinder 1. The cylinder 1 is provided with an air inlet pipe 2 and a water removal pipe 4; the water removal pipe 4 is provided with an automatic drain valve, which can automatically discharge the liquid accumulated to a certain extent in the cylinder 1. It can be understood that the automatic drain valve is a prior art, which is not drawn in the figure and will not be described in detail; the cleaning mechanism 5 includes: a centrifugal wheel 51, the centrifugal wheel 51 is rotatably connected to the inner wall of the cylinder 1, and the centrifugal wheel 51 The axis coincides with the axis of the air outlet pipe 3; a gap is left between the centrifugal wheel 51 and the inner wall of the cylinder 1, so that the internal compressed air of the cylinder 1 is connected with the air outlet pipe 3 through the gap; a collecting cover 52, the collecting cover 52 is arranged on the cylinder 1, and the collecting cover 52 is arranged on the centrifugal wheel 51; the collecting cover 52 is used to collect liquid water and oil stains thrown out when the centrifugal wheel 51 rotates; and a driving mechanism 53, the driving mechanism 53 is installed on the air outlet pipe 3, and the output end of the driving mechanism 53 is connected to the centrifugal wheel 51; the driving mechanism 53 is used to drive the centrifugal wheel 51 to rotate along the axis of the air outlet pipe 3.

[0043] It should be noted that when the air outlet pipe 3 is opened to allow the compressed air to be discharged, the centrifugal wheel 51 is driven to rotate through the driving mechanism 53, so that the centrifugal wheel 51 pushes the compressed air entering the collecting cover 52 to be centrifugal, that is, at this time, the liquid water and oil with higher density carried by the compressed air are thrown onto the collecting cover 52 under the action of centrifugal force, so that the liquid water and oil flow downward along the side wall of the collecting cover 52 under the action of gravity and are discharged, thereby realizing automatic cleaning of the compressed air when it is discharged, improving the cleanliness of the compressed air, reducing the corrosion of the pipeline system by the liquid water and oil carried by the compressed air, and increasing the service life of the equipment.

[0044] like Figure 3-4 and Figure 8 As shown, the collecting hood 52 includes an enclosure 521 arranged on the inner wall of the cylinder 1 and a cover body 522 arranged on the enclosure 521; a through hole is opened on the cover body 522, and the compressed air in the cylinder 1 enters the collecting hood 52 through the through hole. After centrifugation by the rotation of the centrifugal wheel 51, the liquid water and oil are thrown onto the enclosure 521. Under the action of gravity, the liquid water and oil are discharged from the bottom of the enclosure 521, and the compressed air after centrifugation is discharged through the gap and the outlet pipe 3; the enclosure 521 includes a first guide portion 5211 arranged at the top and tilted downward, and a second guide portion 5212 arranged at the bottom to form an opening.

[0045] It should be noted that, before the compressed air enters the air outlet pipe 3, it first enters the collecting cover 52 from the through hole on the cover body 522, and by driving the centrifugal wheel 51 to rotate, the liquid water and oil carried by the compressed air are thrown onto the enclosure 521. When the liquid water and oil are thrown onto the top inner wall of the enclosure 521, that is, the first guide part 5211, since the first guide part 5211 is a downwardly curved arc structure, the setting of the arc structure can reduce the angle between it and the direction of gravity. Therefore, under the influence of gravity and the viscosity of the liquid water and oil, the liquid water and oil will flow along the enclosure 521. The inner wall of the enclosure 521 slides downward instead of dripping directly downward until the liquid water and oil are guided out from the second guide portion 5212 to the interior of the cylinder 1, thereby realizing the automatic guidance of the liquid water and oil after separation, and ensuring the continuous cleaning effect of the compressed air; when the liquid water and oil carried by the compressed air are thrown to the side and bottom of the enclosure 521, the angle between the side and bottom structures and the direction of gravity is also small at this time. Therefore, under the influence of gravity and the viscosity of the liquid water and oil, the liquid water and oil will slide downward along the side wall of the enclosure 521 to be guided out, thereby realizing the purpose of automatic collection of the liquid water and oil.

[0046] like Figure 1-5As shown, it can be understood that the present application does not limit the specific structure and installation method of the driving mechanism 53, and only a feasible specific scheme is provided below; the driving mechanism 53 includes a motor 531, a driving bevel gear 532 and a driven bevel gear 533; the motor 531 is installed in the air outlet pipe 3, the driving bevel gear 532 is coaxially connected to the output end of the motor 531, the driven bevel gear 533 is installed in the air outlet pipe 3, and the driven bevel gear 533 is meshed with the driving bevel gear 532; the driven bevel gear 533 is connected to the coaxial centrifugal wheel 51.

[0047] It should be noted that, since the centrifugal force generated by the compressed air through the centrifugal wheel 51 will cause the derived compressed air to lose a part of its pressure, at this time, a certain thrust is provided by the thrust mechanism 54 to compensate for the pressure loss when cleaning the compressed air; specifically, when the active bevel gear 532 is driven to rotate by the motor 531, the active bevel gear 532 drives the driven bevel gear 533 to rotate, and the driven bevel gear 533 drives the screw rod 542 to rotate, and the compressed air in the air outlet pipe 3 is pushed to move quickly by the screw rod 542, so as to compensate for the pressure loss when cleaning the compressed air, and the rotation of the screw rod 542 will also drive the centrifugal wheel 51 to rotate, without affecting the cleaning work of the compressed air by the rotation of the centrifugal wheel 51.

[0048] like Figure 4-5 and Fig. 9 As shown, the cleaning mechanism 5 also includes a thrust mechanism 54, which is arranged between the output end of the driving mechanism 53 and the centrifugal wheel 51, and the thrust mechanism 54 is installed in the air outlet pipe 3; the thrust mechanism 54 is used to promote the movement of compressed air to offset the pressure loss caused by the flow of compressed air when the centrifugal wheel 51 rotates; the thrust mechanism 54 includes a first mounting plate 541 and a screw rod 542; the first mounting plate 541 is a hollow structure, and the first mounting plate 541 is arranged in the air outlet pipe 3, the screw rod 542 is arranged in the air outlet pipe 3, and the screw rod 542 is coaxially connected to the air outlet pipe 3; the screw rod 542 is rotatably connected to the first mounting plate 541, one end of the screw rod 542 is coaxially connected to the driven bevel gear 533, and the other end of the screw rod 542 is coaxially connected to the centrifugal wheel 51.

[0049] It should be noted that, since the centrifugal force generated by the compressed air through the centrifugal wheel 51 will cause the derived compressed air to lose a part of its pressure, at this time, a certain thrust is provided by the thrust mechanism 54 to compensate for the pressure loss when cleaning the compressed air; specifically, when the active bevel gear 532 is driven to rotate by the motor 531, the active bevel gear 532 drives the driven bevel gear 533 to rotate, and the driven bevel gear 533 drives the screw rod 542 to rotate, and the compressed air in the air outlet pipe 3 is pushed to move quickly by the screw rod 542, so as to compensate for the pressure loss when cleaning the compressed air, and the rotation of the screw rod 542 will also drive the centrifugal wheel 51 to rotate, without affecting the cleaning work of the compressed air by the rotation of the centrifugal wheel 51.

[0050] like Figure 4-7 and Fig. 9 As shown, the cleaning mechanism 5 also includes a planetary gear mechanism 55. It can be understood that the present application does not limit the specific structure and installation method of the planetary gear mechanism 55. The following only provides a feasible specific solution; the planetary gear mechanism 55 is arranged between the thrust mechanism 54 and the centrifugal wheel 51; the planetary gear mechanism 55 includes a second mounting plate 551, a sun gear 552, a planetary gear 553 and an inner gear ring 554; the second mounting plate 551 is arranged in the air outlet pipe 3, and the spiral rod 542 is away from the first mounting plate 54 One end of the second mounting plate 551 is rotatably connected to the second mounting plate 551, the sun gear 552 is coaxially connected to the screw rod 542, a plurality of planetary gears 553 are rotatably connected to the second mounting plate 551, the sun gear 552 is meshed with the plurality of planetary gears 553, the inner gear ring 554 is rotatably connected to the second mounting plate 551, and the plurality of planetary gears 553 are all meshed with the inner gear ring 554; a gap is left between the second mounting plate 551 and the air outlet pipe 3, and the compressed air is introduced into the air outlet pipe 3 through the gap after passing through the centrifugal wheel 51.

[0051] It should be noted that, in order to accurately control the relative rotation speed of the screw rod 542 and the centrifugal wheel 51, the pressure loss of the compressed air caused by the centrifugal wheel 51 can be exactly compensated by the screw rod 542. At this time, the relative rotation speed between the screw rod 542 and the centrifugal wheel 51 is changed by setting the planetary gear mechanism 55. Since the structure of the planetary gear mechanism 55 will make the rotation directions of the screw rod 542 and the centrifugal wheel 51 opposite, it is necessary to adjust the direction of the screw rod 542 so that when the centrifugal wheel 51 rotates to generate centrifugal force, the screw rod 542 can push the compressed air to be discharged; specifically, when the driving mechanism 53 drives the screw rod 542, the screw rod 542 is rotated to generate centrifugal force. When the sun gear 42 rotates, the screw rod 542 drives the sun gear 552 to rotate, which drives the planetary gear 553 to rotate through the sun gear 552, which drives the inner gear ring 554 to rotate through the planetary gear 553, and drives the centrifugal wheel 51 to rotate through the inner gear ring 554. The relative speed between the screw rod 542 and the centrifugal wheel 51 can be determined by the gear ratio between the sun gear 552 and the inner gear ring 554, so that the screw rod 542 and the centrifugal wheel 51 have a suitable relative speed, so that the pressure loss caused by the operation of the centrifugal wheel 51 is just compensated by the screw rod 542, thereby ensuring that a suitable pressure is generated when the compressed air is discharged.

[0052] like Figure 4-7 and Fig.10 As shown, the cleaning mechanism 5 also includes a filtering mechanism 56; the filtering mechanism 56 is arranged between the second mounting plate 551 and the air outlet pipe 3; the filtering mechanism 56 is used to filter the compressed air passing through the gap to clean the liquid water and oil carried by the compressed air; the filtering mechanism 56 includes a butterfly spring pad 561 and a filter screen 562; the butterfly spring pad 561 is a conical annular structure, the outer ring of the butterfly spring pad 561 is connected to the inner wall of the air outlet pipe 3, and the filter screen 562 is arranged between the butterfly spring pad 561 and the second mounting plate 551; the butterfly spring pad 561 has a plurality of open grooves 563 arranged in an evenly spaced array along the circumference of its axis; the open grooves 563 are used to allow the butterfly spring pad 561 to deform after being subjected to force; an isolation membrane 564 is arranged on the open groove 563; the isolation membrane 564 is used to allow the compressed air to be introduced into the air outlet pipe 3 only after being filtered by the filter screen 562, so as to improve the filtering effect of the compressed air; it should be noted that the arrows in Figures 5-6 are the movement trajectories of the compressed air.

[0053] It should be noted that when the compressed air is cleaned by the centrifugal force generated by the rotation of the centrifugal wheel 51, it is still possible that some liquid water and oil will be carried out due to the flow of the compressed air. Therefore, a filtering structure is provided in the flow of the compressed air to further improve the cleaning effect of the compressed air; specifically, when the compressed air passes through the gap between the outlet pipe 3 and the second mounting plate 551 after being centrifugally cleaned by the rotation of the centrifugal wheel 51, the compressed air will pass through the filter 562 and then be discharged from the outlet pipe 3. The compressed air is further cleaned and filtered by the filter 562 to improve the cleanliness of the compressed air; it can be understood that the filter 562 is an existing structure, which can be a hydrophilic fiber mesh structure;

[0054] Furthermore, through the arrangement of the butterfly spring pad 561, when the air outlet pipe 3 is opened and the driving mechanism 53 drives the spiral rod 542 to rotate, negative pressure is generated in the air outlet pipe 3, while the compressed air on the other side generates positive pressure. Under the action of the air pressure, the butterfly spring pad 561 is pushed to deform, so that the butterfly spring pad 561 pulls the filter screen 562 to a certain extent, which can improve the passing efficiency of the compressed air. When the compressed air is discharged and the spiral rod 542 does not rotate, the butterfly spring pad 561 loses the negative pressure on one side. Under the influence of air pressure, the deformation will be restored. At this time, the filter screen 562 will be pushed to be squeezed, and the liquid water and oil absorbed by the filter screen 562 will be discharged, which is beneficial to its continuous long-term filtering work. The squeezed filter screen 562 cooperates with the butterfly spring pad 561, so that the compressed air in the cylinder 1 and the air outlet pipe 3 form a certain degree of isolation and sealing, which can reduce the leakage loss of compressed air when the valve and other structures on the air outlet pipe 3 are damaged, form a certain isolation, prevent debris from entering the cylinder 1, and improve the protection of the inside of the cylinder 1.

[0055] like Figure 1-11 As shown, a method for using a vehicle air cylinder cleaning device comprises the following steps:

[0056] Step 1: Transport and clean: When the air outlet pipe 3 is opened, the compressed air in the cylinder 1 is discharged, and the centrifugal wheel 51 is driven to rotate by the driving mechanism 53, so that the compressed air flowing through the centrifugal wheel 51 is centrifuged, and the liquid water and oil carried by the compressed air are thrown onto the collecting cover 52. The liquid water and oil slide down along the inside of the collecting cover 52 under the action of gravity, thereby achieving the purpose of cleaning the compressed air when it is discharged, and the cleaned compressed air passes through the gap and is discharged through the air outlet pipe 3;

[0057] Step 2, pressure compensation: After the compressed air is cleaned by the rotation of the centrifugal wheel 51, the thrust mechanism 54 pushes the compressed air to flow quickly to compensate for the pressure loss caused by cleaning the compressed air, thereby ensuring that the compressed air is clean without affecting its normal use.
