DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship 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. Therefore, they should not be understood as limitations on the present invention.

[0023] The present invention provides a water supply and drainage channel, comprising a pipe body 1 having an opening 2 and a sealing portion 3 for sealing the opening 2. A cleaning assembly is disposed within the pipe body 1, comprising a take-up roller 4, a cleaning component, and a connecting cable 5. The take-up roller 4 is rotatably connected to the sealing portion 3. The cleaning component comprises a base 6 housed within the pipe body 1. The base 6 is rotatably provided with rotating blades 8, each of which is provided with a cleaning component 9. A connecting cable 5 is wound around the take-up roller 4 and connected to the base 6.

[0024] The pipe body 1 is used for conveying a medium. For example, the pipe body 1 can be used for water supply or drainage.

[0025] The opening 2 is used to take the cleaning component out of the tube body 1 .

[0026] Since the cleaning component is housed within the tube body 1, the rotating blades 8 are suspended within the tube body 1 via the base 6. When a medium passes through the tube body 1, the rotating blades 8 rotate, causing the cleaning portion 9 provided on the rotating blades 8 to rotate along with it, thereby cleaning the inner wall of the tube body 1. Furthermore, when water flows into the rotating blades 8, the cleaning component is also moved along the axial direction of the tube body 1, thereby cleaning the tube body 1 in the axial direction.

[0027] The winding roller 4 is used to wind up the connecting rope 5. On the one hand, when the cleaning component is pushed and moved by the medium, the cleaning component can be reset by the winding roller 4. On the other hand, by calculating the unwinding length of the connecting rope 5, the moving distance of the cleaning component can be judged, and then the position of the cleaning component in the tube body 1 can be judged, and by counting the number of rotations of the winding roller 4, the unwinding length of the connecting rope 5 can be calculated. In the embodiment of the present application, the sealing portion 3 can be provided with a detection component to detect the number of rotations of the winding roller 4, and the cleaning component can also include a driving component for driving the winding roller 4 to rewind and unwind the connecting rope 5. Both the detection component and the driving component can be selected from existing products. For example, the detection component can include a sensor and a processor, and the driving component can include a motor. The usage of the detection component and the driving component is well known to those skilled in the art and will not be repeated here.

[0028] In some embodiments, a plurality of abutment wheel sets 7 are spaced apart on the seat body 6 around the inner circumferential wall of the tube body 1 .

[0029] The abutting wheel set 7 is used to reduce the friction between the seat body 6 and the inner wall of the tube body 1 on the one hand, and on the other hand, enables the seat body 6 to be suspended inside the tube body 1, thereby allowing the rotating blades 8 to rotate under the action of the medium in the tube body 1.

[0030] In some embodiments, the abutting wheel assembly 7 includes an arm 15 and a wheel body 16. The arm 15 is rotatably connected to the base 6, and a torsion spring is provided between the arm 15 and the base 6. The wheel body 16 is rotatably connected to the arm 15 and abuts against the inner wall of the tube body 1.

[0031] Under the action of the arm 15 , the position of the wheel body 16 relative to the base body 6 can be changed, thereby increasing the passability of the cleaning component in the tube body 1 .

[0032] The torsion spring is used to provide an elastic force that enables the wheel body 16 to abut against the inner wall of the tube body 1. Compared with a spring, the use of a torsion spring can reduce the space occupied by the wheel set 7.

[0033] In some embodiments, a plurality of abutting wheel sets 7 are provided along the axial direction of the tube body 1 .

[0034] The advantage of providing a plurality of abutment wheel groups 7 along the axial direction of the tube body 1 is that the movement stability of the cleaning component can be improved. For example, among the multiple abutment wheel groups 7, when the wheel body 16 of one of the abutment wheel groups 7 is retracted toward the base body 6, the other abutment wheel groups 7 can remain against the inner wall of the tube body 1, reducing the risk of large radial displacement of the cleaning component relative to the tube body 1.

[0035] In some embodiments, along the flow direction of the medium in the pipe body 1 , the arm portion 15 is arranged to tilt backward.

[0036] In the embodiment of the present application, the arm 15 can be curved, with the inner curved side of the arm 15 facing the inner wall of the tube body 1. The advantage of this arrangement is that it can increase the structural strength of the arm 15 along the radial direction of the tube body 1 and reduce the risk of deformation of the arm 15.

[0037] The arm portion 15 is tilted backward, which reduces the risk of the arm portion 15 being damaged when the wheel body 16 abuts against the protrusion of the inner wall of the tube body 1.

[0038] In some embodiments, the rotating blade 8 includes an inner shaft 14, an outer ring 11, and blades 10. The inner shaft 14 is rotatably connected to the base 6, the outer ring 11 is arranged around the circumference of the inner shaft, the cleaning portion 9 is arranged on the outer ring 11, and the blades 10 are arranged between the inner shaft 14 and the outer ring 11.

[0039] The inner shaft 14 enables the rotating blade 8 to be rotatably connected to the base 6 .

[0040] On the one hand, the outer ring body 11 allows the cleaning portion 9 to be arranged as close to the edge of the rotating blade 8 as possible, thereby ensuring that the cleaning portion 9 can contact the inner wall of the tube body 1 so that the cleaning portion 9 can perform a cleaning function. On the other hand, the outer ring body 11 can protect the fan blade 10.

[0041] Under the action of the fan blades 10 , when the medium passes through the rotating blades 8 , the rotating blades 8 can rotate relative to the base 6 .

[0042] In some embodiments, the cleaning portion 9 is a spherical structure formed by winding multiple sections of steel wire.

[0043] On the one hand, the structure of the cleaning part 9 with steel wire winding makes the cleaning part 9 fluffy, ensuring that the cleaning part 9 can fully contact the inner wall of the tube body 1, thereby improving the cleaning effect. On the other hand, the garbage brushed off by the cleaning part 9 can be stuck inside the cleaning part 9, that is, the garbage can be taken out from the inside of the tube body 1 after cleaning.

[0044] In some embodiments, a recess 13 is provided on the peripheral wall surface of the outer ring body 11 around the circumference of the outer ring body 11 , and the rotating blade 8 further includes a clamp 12 , which is provided around the circumference of the recess 13 , and the cleaning portion 9 is partially accommodated in the recess 13 .

[0045] The structure of the clamp 12 can be selected from existing structures and will not be described in detail here.

[0046] The recessed portion 13 is used to position the cleaning portion 9 on one hand, and is used to position the clamp 12 on the other hand, thereby improving the fixing effect of the cleaning portion 9 through the clamp 12 .

[0047] Under the action of the clamp 12, the cleaning part 9 is detachably connected to the ring body, which facilitates cleaning and maintenance of the cleaning part 9. In addition, the clamp 12 can simultaneously fix multiple cleaning parts 9, that is, multiple cleaning parts 9 can be combined so that the cleaning parts 9 can be arranged around the circumference of the outer ring body 11. On the one hand, this increases the cleaning range, and on the other hand, individual cleaning parts 9 can be replaced separately, reducing costs.

[0048] In some embodiments, the blocking portion 3 is a cover-shaped structure, the blocking portion 3 covers the opening 2 , and the winding roller 4 is accommodated in the blocking portion 3 .

[0049] The cover-like structure of the sealing portion 3 allows a chamber to be formed inside the sealing portion 3, which forms a space for installing the winding roller 4, reducing the risk of the winding roller 4 occupying the internal space of the tube body 1 and causing a reduction in the conveying capacity of the tube body 1. At the same time, the winding roller 4 is installed in the sealing portion 3 to facilitate the disassembly and assembly of the winding roller 4.

[0050] In some embodiments, the blocking portion 3 is connected to the pipe body 1 by bolts.

[0051] The blocking portion 3 may be provided with a connecting wall portion, and the connecting wall portion is connected to the pipe body 1 by bolts.

[0052] The sealing portion 3 is connected to the tube body 1 via bolts. This improves the reliability of the connection between the sealing portion 3 and the tube body 1. Furthermore, it allows the sealing portion 3 to be detachably connected to the tube body 1, facilitating the removal of cleaning components. For example, before cleaning, the cleaning component is placed into the tube body 1 through the opening 2, and then the sealing portion 3 is connected to the tube body 1 to seal the opening. After cleaning, the sealing portion 3 can be opened again to remove the cleaning component from the tube body 1.

[0053] In some embodiments, the pipe body may also be provided with a cover plate, which may also be bolted to the pipe body and used to seal the opening. Under the action of the cover plate and the blocking portion 3, the water supply and drainage channel can have two operating states: one is to remove the cover plate, insert the cleaning component into the pipe body 1, and then use the blocking portion 3 to block the opening 2, and then use the cleaning component to clean the interior of the pipe body 1. The other is to remove the cleaning component, remove the blocking portion 2 from the pipe body 1, and use the cover plate to block the opening 2.

[0054] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, alterations, and substitutions of the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
