DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0031] Example:

[0032] Reference Figure 1-Figure 7A rotary spraying device comprises a box 13 of a cubic structure, wherein the box 13 has at least one open end for placing parts to be sprayed inside.

[0033] The top of the box body 13 is fixedly connected to a bottom pressure cover, and a fixing seat 3 is fixedly connected to the bottom pressure cover. The water inlet cylinder 1 in a rotating body structure is sleeved on the outer circumferential surface of the fixing seat 3. The top of the water inlet cylinder 1 is fixedly connected to a top pressure cover 2. The top pressure cover 2, the bottom pressure cover and the water inlet cylinder 1 form a structure in which the upper and lower ends are sealed. A sealing ring 6 and a packing 5 made of Teflon or Teflon are arranged between the fixing seat 3 and the driving cylinder 8 to improve the sealing effect. A water inlet pipe 7 is arranged on the side wall of the water inlet cylinder 1. The driving cylinder 8 is rotatably connected to the inner sleeve of the water inlet cylinder 1, and the axis of the driving cylinder 8 coincides with the axis of the water inlet cylinder 1. A bearing 4 is arranged between the top pressure cover 2 and the driving cylinder 8 to ensure the stability of the rotation of the driving cylinder 8 and prevent shaking.

[0034] An annular cavity structure is formed between the water inlet cylinder 1 and the driving cylinder 8, wherein the driving cylinder 8 extends into the box body 13, and the side wall of the driving cylinder 8 is provided with at least two groups of through holes, one row of through holes is connected to the cavity, and the other row of through holes is connected to the spray pipe 11. When water enters from one row of through holes and is discharged from the other row of through holes, the driving cylinder 8 rotates.

[0035] Here, two rows of through holes are preferably provided, which can ensure normal water flow in and out on the one hand, and can ensure the strength reliability of the driving cylinder 8 when rotating at high speed on the other hand.

[0036] In the above structural design, an external high-pressure water flow flows into the operating cavity, and then the water in the annular cavity enters the driving cylinder 8 through the upper row of through holes, and then is discharged from the lower row of through holes into the spray pipe 11. During the flow of high-pressure water, the water flow in and out of the driving cylinder 8 will push the driving cylinder 8 to rotate around its own axis, thereby driving the spray pipe 11 to rotate, thereby replacing the method of driving the spray pipe 11 to rotate by the motor. It can not only greatly reduce power consumption and maintenance costs, but also can adjust the rotation speed of the spray pipe 11 by the size of the incoming water pressure, so as to better clean the parts, and ensure that the water inlet cylinder 1 and the driving cylinder 8 rotate concentrically, further avoiding shaking during rotation.

[0037] Reference Figure 6On the basis of the above structural design, an acceleration part is provided in the driving cylinder 8 to increase the self-rotation force of the driving cylinder 8. A specific form of the acceleration part is at least one spiral sheet 14, which is fixedly connected to the inner wall of the driving cylinder 8 and arranged between two rows of through holes. Here, we preferably provide three groups of spiral sheets 14, and the three groups of spiral sheets 14 are equidistantly distributed in the driving cylinder 8. When water flows into the upper through holes and is discharged from the lower through holes, the flowing water will pass through the spiral sheets 14, thereby further promoting the rotation of the driving cylinder 8, thereby increasing the rotation speed of the driving cylinder 8.

[0038] Reference Figure 7 Of course, another form is that the acceleration part includes at least one spiral tube 15, the cross-sectional diameter of the spiral tube 15 is the same as the diameter of the through hole, and the spiral tube 15 is fixedly connected to any through hole. The purpose is to directly guide the water flow to turn at the water entry and discharge position, thereby acting in the opposite direction on the driving cylinder 8 to rotate the driving cylinder 8, which can also further increase the rotation speed of the driving cylinder 8.

[0039] Here, the specific through holes include a first through hole 9 and a second through hole 10, the plane where the axis of the first through hole 9 is located is parallel to the plane where the axis of the second through hole 10 is located, and the first through hole 9 is located in the water inlet cylinder 1, the second through hole 10 is located in the box body 13, and the second through hole 10 is connected to the water inlet end of the spray pipe 11.

[0040] Specifically, the spray pipe 11 is "L"-shaped. The short tube of the spray pipe 11 is connected to the second through hole 10. A nozzle 12 is arranged on the long tube of the spray pipe 11. The nozzle 12 is provided in 3-6 groups, and multiple groups of nozzles 12 are arranged on the long tube at equal intervals. Through multiple evenly arranged nozzles 12, all-round and dead-angle-free cleaning of parts can be further achieved.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
