DETAILED DESCRIPTION

[0042] 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.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figure 1-Figure 6 The present invention provides a physical training equipment cleaning device, comprising:

[0045] The cleaning box 1 has a feed inlet and a discharge inlet respectively defined on opposite sides of the top;

[0046] The cleaning cylinder 2 is rotatably connected in the cleaning box 1. The cleaning cylinder 2 is provided with a plurality of receiving grooves in the circumference thereof. The receiving grooves are used to receive spherical instruments. The receiving grooves at the lowest end of the cleaning cylinder 2 are immersed in water.

[0047] The cleaning assembly includes a cleaning roller 3 rotatably connected to the bottom of the cleaning box 1, a brush 4 is fixedly connected to the outer peripheral side of the cleaning roller 3, and a first driving member is provided in the cleaning box 1, and the driving end of the first driving member is connected to the cleaning roller 3, so that the cleaning roller 3 reciprocates through the notch of the lowest end receiving groove, and the brush 4 is in sliding contact with the spherical device in the receiving groove;

[0048] The locking assembly is arranged in the receiving groove. When the receiving groove at the lowest end accommodates a spherical device, the locking assembly is used to fix the cleaning cylinder 2 relative to the cleaning box 1.

[0049] In the present technical scheme, a plurality of receiving grooves are provided on the cleaning cylinder 2, and the receiving grooves are used to buckle the spherical instruments in the receiving grooves during the rotation of the cleaning cylinder 2. As the cleaning cylinder 2 rotates, the receiving grooves carry the spherical instruments and immerse them in water. The spherical instruments are cleaned in combination with the cleaning rollers 3 arranged in the cleaning box 1. The cleaning rollers 3 are driven by the first driving member to reciprocate through the notches of the receiving grooves at the lowest end, and the brushes 4 on the cleaning rollers 3 are used for cleaning. After the spherical instruments are immersed in water, the locking assembly can fix the cleaning cylinder 2 to ensure the cleaning effect of the cleaning rollers 3. After a period of cleaning, the cleaning cylinder 2 rotates to drive the receiving grooves to extend out of the water, thereby continuously conveying the spherical instruments in the direction from the feed port to the discharge port, thereby improving the cleaning efficiency.

[0050] In the present technical solution, the receiving groove can accommodate a number of spherical devices (such as common basketballs, footballs, etc.) at a time. During the rotation of the cleaning cylinder 2, the edge of the receiving groove pushes the spherical device placed in the direction of the feed port, so that the spherical device enters the receiving groove and is then pressed into the water by the cleaning cylinder 2 to clean the spherical device at the bottom of the cleaning box 1.

[0051] Further, the locking assembly includes:

[0052] A pressure plate 5 is elastically connected to the inner wall of the bottom end of the receiving groove. A pressure sensor 6 is arranged in the receiving groove. The pressure sensor 6 is used to obtain a pressure signal of the pressure plate 5.

[0053] The locking part is arranged on the cleaning box 1, has a switchable locking or unlocking state, and is communicatively connected to the pressure sensor 6. The locking end of the locking part is connected to the cleaning cylinder 2. Only when the pressure plate 5 obtains a vertically upward pressure signal, the locking part switches to a locking state to fix the cleaning cylinder 2.

[0054] The locking portion is used to control the rotation state of the cleaning cylinder 2. Under normal circumstances, it is in the unlocked state. The cleaning cylinder 2 rotates to immerse the spherical device in water, and the pressure plate 5 and the pressure sensor 6 cooperate to detect whether there is a spherical device sent into the receiving groove, thereby ensuring that when the cleaning cylinder 2 is fixed, there is a spherical device in the lowest end receiving groove to be cleaned by the cleaning roller 3.

[0055] Furthermore, the pressure plate 5 is configured such that the elastic force in the direction away from the receiving groove is greater than the gravity of the spherical device and less than the buoyancy of the spherical device.

[0056] The buoyancy generated by the spherical device immersed in water is used to form an external force acting vertically upward on the pressure plate 5, so as to detect whether the spherical device is effectively sent to the receiving tank. When there is no spherical device in the receiving tank or the spherical device is not sent into the water, that is, it is located in the upper receiving tank, the elastic force of the pressure plate 5 can support the spherical device, so that the pressure sensor 6 cannot obtain the pressure signal, thereby avoiding locking the cleaning cylinder 2, and allowing the cleaning cylinder 2 to rotate to transport the spherical device.

[0057] Further, the locking portion includes:

[0058] The locking housing 7 is fixedly connected to one side of the outer wall of the cleaning box 1. The axis of the cleaning cylinder 2 is fixedly connected to a rotating rod 8, which is connected to the cleaning box 1, and one end of the rotating rod 8 penetrates the cleaning box 1 and extends into the locking housing 7.

[0059] The first locking half ring 9 is slidably connected in the locking shell 7. A connecting ring 10 is sleeved on the part of the rotating rod 8 extending into the locking shell 7. The connecting ring 10 is fixedly connected to the rotating rod 8. The side of the first locking half ring 9 close to the connecting ring 10 is in contact with or not in contact with the connecting ring 10. When the first locking half ring 9 is in contact with the connecting ring 10, the rotating rod 8 is fixed to the cleaning box 1.

[0060] By extending the rotating rod 8 into the locking housing 7, the rotating rod 8 is fixedly connected to the cleaning cylinder 2, and the first locking plate is used to abut or not contact the connecting ring 10, so that the connecting ring 10 is fixed by the first locking plate, and the rotating rod 8 and the cleaning cylinder 2 are fixed to the cleaning box 1.

[0061] Furthermore, it also includes:

[0062] The servo motor 11 is fixedly connected to one side of the locking housing 7 through a motor plate, and the motor plate is fixedly connected to the cleaning box 1. The output shaft of the servo motor 11 is fixedly connected to a screw 12, and the external thread of the screw 12 is provided with a sleeve 13. The end of the sleeve 13 away from the servo motor 11 is fixedly connected to a first connecting plate 14, and the first connecting plate 14 is limitedly slidably connected in the locking housing 7, and the first connecting plate 14 is fixedly connected to the first locking half ring 9, and the servo motor 11 is communicatively connected to the pressure sensor 6.

[0063] The servo motor 11 is driven and controlled by the pressure sensor 6. When a spherical device is retained in the receiving groove at the lowest end, the buoyancy of the spherical device lifts the pressure plate 5, triggering the pressure sensor 6 to obtain a pressure signal, thereby turning on the servo motor 11.

[0064] The servo motor 11 drives the screw 12 to rotate, so that the sleeve 13 moves along the axial direction of the screw 12. The sleeve 13 is fixedly connected to the first locking semi-ring 9 through the first connecting plate 14. The locking shell 7 limits the first connecting plate 14, so that the sleeve 13 drives the first locking semi-ring 9 to move toward the connecting ring 10. After the first locking semi-ring 9 and the connecting ring 10 are against each other, the rotating rod 8 is fixed to the cleaning box 1.

[0065] Furthermore, it also includes:

[0066] The second locking half ring 15 is arranged opposite to the first locking half ring 9, and the second locking half ring 15 is slidably connected in the locking housing 7;

[0067] The transmission assembly is arranged on the locking housing 7, and the first locking half ring 9 is connected with the second locking half ring 15 through the transmission assembly so that the first locking half ring 9 and the second locking half ring 15 can move closer to or farther from each other.

[0068] Furthermore, the transmission assembly includes:

[0069] The transmission housing 16 is fixedly connected to the side of the locking housing 7 away from the cleaning box 1, and the transmission housing 16 is communicated with the locking housing 7;

[0070] The first transmission rod 17 is slidably connected in the transmission housing 16, and one end of the first transmission rod 17 is fixedly connected to the first connecting plate 14;

[0071] The second transmission rod 18 is slidably connected in the transmission housing 16 and is distributed opposite to the first transmission rod 17. One end of the second transmission rod 18 extends into the locking housing 7 and is fixedly connected to a second connecting plate 19. The second connecting plate 19 is fixedly connected to the second locking half ring 15.

[0072] A pair of toothed plates 20 are fixedly connected to the first transmission rod 17 and the second transmission rod 18 respectively. A gear 21 is centrally connected in the transmission housing 16. The pair of toothed plates 20 mesh with two sides of the gear 21 in opposite directions.

[0073] In the present technical solution, a second locking half-ring 15 is arranged corresponding to the first locking half-ring 9. The servo motor 11, the screw 12 and the sleeve 13 are used to drive the first locking half-ring 9 to slide. The first locking half-ring 9 drives the first transmission rod 17 to move through the first connecting plate 14, and the first transmission rod 17 drives the connected toothed plate 20 to slide and drives the gear 21 to rotate, and the other toothed plate 20 meshing on the other side of the gear 21 slides, thereby driving the second transmission rod 18 to slide, and the second transmission rod 18 drives the second connecting plate 19 and the second locking half-ring 15 to slide, so as to realize the first locking half-ring 9 and the second locking half-ring 15 approaching or moving away from each other.

[0074] The first locking half ring 9 and the second locking half ring 15 cooperate to abut and fix the connecting ring 10, thereby fully improving the fixing stability between the rotating rod 8 and the cleaning box 1, and avoiding the situation where the cleaning cylinder 2 rotates and deviates when the brush 4 scrapes and cleans the spherical instrument when the cleaning roller 3 rotates.

[0075] Furthermore, a plurality of receiving grooves are provided, and the plurality of receiving grooves are evenly spaced around the cleaning tube 2. A support rod 22 is slidably connected to the inner wall at the bottom end of the receiving groove. One end of the support rod 22 is fixedly connected to the pressure plate 5, and a spring 23 is wound around the support rod 22. Both ends of the spring 23 are respectively fixedly connected to the pressure plate 5 and the inner wall at the bottom end of the receiving groove. An empty groove is opened in the cleaning tube 2, and a pressure sensor 6 is fixedly connected in the empty groove. The other end of the support rod 22 extends into the empty groove and is fixedly connected to a pressure rod 24. The pressure rod 24 is used to contact the pressure sensor 6.

[0076] The support rod 22 is slidably connected in the receiving groove, and the spring 23 is wound around the support rod 22, so that the pressure plate 5 is elastically connected to the receiving groove. When the receiving groove rotates below the water surface with the rotation of the cleaning tube 2, the buoyancy of the spherical device lifts the pressure plate 5, driving the support rod 22 to lift the pressure rod 24, and the pressure sensor 6 is squeezed by the pressure rod 24, so as to obtain the pressure signal of the pressure plate 5.

[0077] Furthermore, the first driving member includes:

[0078] The turntable 25 is connected to the bottom of the cleaning box 1. The top surface of the turntable 25 is provided with a plurality of through slots at equal intervals in the circumferential direction. The number of the cleaning rollers 3 is the same as that of the through slots and they correspond one to one. The cleaning rollers 3 are connected to the through slots. A first driving motor 26 is fixedly connected to the turntable 25. The output shaft of the first driving motor 26 is coaxially fixedly connected to the cleaning rollers 3.

[0079] The support rod 27 is fixedly connected to the turntable 25 via a connecting frame. A second drive motor 28 is fixedly connected to the bottom end of the cleaning box 1 . The output shaft of the second drive motor 28 is coaxially fixedly connected to the support rod 27 .

[0080] In this technical solution, one end of the support rod 27 is fixedly connected to the output shaft of the second drive motor 28, and the top of the support rod 27 is fixedly connected to the support seat 29, and the ends of several cleaning rollers 3 away from the first drive motor 26 are transferred to the support seat 29 to improve the support stability of the cleaning rollers 3.

[0081] In one embodiment of the present technical solution, the support rod 27 can adopt a retractable structure such as a cylinder or an oil cylinder. The support rod 27 is rotated by the second drive motor 28, and the support rod 27 drives the turntable 25 to rotate. It can be understood that the support rod 27 is fixed to the turntable 25 through a connecting frame, and the connecting frame includes a fixed ring 30 and a plurality of telescopic rods 31. The fixed ring 30 is fixedly connected to the fixed end of the support rod 27, and the two ends of the plurality of telescopic rods 31 are respectively fixedly connected to the fixed ring 30 and the turntable 25. When the piston end of the support rod 27 drives the support seat 29 to lift the plurality of cleaning rollers 3, the cleaning roller 3 is connected to the turntable 25, and the turntable 25 and the support seat 29 are synchronously lifted and lowered through the plurality of telescopic rods 31. When cleaning spherical instruments of different sizes, the cleaning roller 3 can be lifted and lowered to ensure that the brush 4 is in sliding contact with the spherical instrument, thereby ensuring the cleaning effect.

[0082] Furthermore, a third drive motor 32 is fixedly connected to one side of the cleaning box 1 , and an output shaft of the third drive motor 32 is fixedly connected to the axis of the cleaning cylinder 2 .

[0083] The third driving motor 32 is coaxially fixed to the rotating rod 8, thereby driving the cleaning cylinder 2 to rotate.

[0084] The working principle of the physical training equipment cleaning device of the present invention is as follows:

[0085] A number of spherical instruments are placed in the cleaning box 1 along the direction of the feed inlet, and the third drive motor 32 is started to drive the cleaning cylinder 2 to rotate. During the rotation of the accommodating tank, some of the spherical instruments are buckled and immersed in water. As the buoyancy of the spherical instruments squeezes the pressure plate 5, the support rod 22 and the pressure rod 24 are lifted to squeeze the pressure sensor 6. The pressure sensor 6 obtains the pressure signal and transmits it to the external controller. The external controller converts it into an electrical signal to start the servo motor 11 and turn off the third drive motor 32. The servo motor 11 rotates the screw 12 to make the sleeve 13 slide and move the first locking semi-ring 9. The first locking semi-ring 9 moves the first connecting plate 14 to drive the first transmission rod 17 to move a tooth plate 20, which is meshed with the two tooth plates 20 through the gear 21, so that the other tooth plate 20 drives the second transmission rod 18 and the second connecting plate 19 to move toward the first transmission rod 17, thereby realizing the second locking semi-ring 15 and the first locking semi-ring 9 moving toward each other to clamp and fix the connecting ring 10, and fix the rotating rod 8 and the cleaning cylinder 2 to the cleaning box 1.

[0086] While the second drive motor 28 drives the turntable 25 to rotate, the first drive motor 26 drives the cleaning roller 3 to rotate, so that the brush 4 repeatedly passes through the notch of the lowest end receiving groove to clean the spherical device in the receiving groove. After cleaning for 1-2 minutes, the servo motor 11 is turned off, and the third drive motor 32 is started (timing can be performed through an external control system. This patent determines whether the spherical device is placed in the receiving groove and immersed in water through the pressure plate 5 and the pressure sensor 6), driving the cleaning cylinder 2 to rotate, repeatedly immersing new spherical devices in water, and the cleaned spherical devices are directly moved to the discharge port to exit the cleaning box 1, completing the cleaning of a large number of spherical devices.

[0087] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0088] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
