[0053] The rotating sleeve 301c is provided with a vertical groove 301c-1 which is connected to the liquid collecting cover 301d. In this embodiment, the vertical groove 301c-1 can connect the liquid collecting cover 301d and the inner wall of the rotating sleeve 301c.

[0054] The rotating assembly 302 is used to rotate the rotating sleeve 301c. In this embodiment, the cleaning angle of the flat-sweeping nozzle 301e can be changed by controlling the rotating sleeve 301c to rotate through the rotating assembly 302.

[0055] Specifically, the rotating assembly 302 includes a fixed frame 302a fixed on the outer wall of the upper sleeve 301a, and a first motor 302b fixed in the fixed frame 302a.

The water source enters the liquid inlet pipe 301b, flows into the interior of the upper sleeve 301a, and enters the liquid collecting cover 301d from the vertical groove 301c-1 on the rotating sleeve 301c, and is sprayed from the flat sweeping nozzle 301e. The fan-shaped water flow sprayed by the flat sweeping nozzle 301e cleans the inner wall of the non-tensioned water tank body 102. During cleaning, the pinion 302d is controlled to rotate by the first motor 302b, which can make the ring gear 302c rotate, and then the rotating sleeve 301c rotates, changing the cleaning angle of the flat sweeping nozzle 301e, realizing multi-angle cleaning, and avoiding the generation of cleaning dead corners. The liquid and impurity mixture generated during cleaning is discharged through the drain pipe 103. After cleaning is completed, water is injected into the non-tensioned water tank body 102 through the filling pipe 202 to complete the cleaning operation.

Different from the previous embodiment, the cleaning mechanism 300 further includes a lifting assembly 303 fixedly arranged at the end of the conveying assembly 301, and a flow guide assembly 304 arranged on the lifting assembly 303. The lifting assembly 303 can control the flow guide assembly 304 to slide on the inner wall of the rotating sleeve 301c;

[0060] The guide assembly 304 includes a guide sleeve 304a slidably arranged on the inner wall of the rotating sleeve 301c, and an upper annular groove 304b and a lower annular groove 304c arranged on the outer wall of the guide sleeve 304a, and also includes a one-way flow component 304d arranged at the end of the guide sleeve 304a; in this embodiment, the outer wall of the guide sleeve 304a is provided with a plurality of evenly distributed sealing structures, which can seal the guide sleeve 304a and the rotating sleeve 301c, the upper annular groove 304b and the lower annular groove 304c are equal in size, and the one-way flow component 304d can block the end of the guide sleeve 304a, so that the liquid entering the guide sleeve 304a cannot flow out from the end where the one-way flow component 304d is located.

[0061] A first through hole 304b-1 is provided on the upper annular groove 304b, and a second through hole 304c-1 is provided on the lower annular groove 304c. In this embodiment, by opening the first through hole 304b-1 and the second through hole 304c-1, liquid can flow from the guide sleeve 304a into the upper annular groove 304b and the lower annular groove 304c respectively, forming a liquid diversion.

[0062] Specifically, a plurality of liquid collecting covers 301d are evenly arranged on the outer wall of the rotating sleeve 301c from bottom to top.

[0063] It should be noted that the liquid collecting cover 301d and the vertical groove 301c-1 are arranged in a one-to-one correspondence. Figure 7 , set the length of the vertical groove 301c-1 to Q1, the axial length of the upper annular groove 304b and the lower annular groove 304c to Q2, the farthest distance between every two adjacent vertical grooves 301c-1 to L1, the farthest distance between the upper annular groove 304b and the lower annular groove 304c to L2, Q1>Q2, L1>L2, L1-Q1≥L2≥Q1, due to Q1>Q2, so when the guide sleeve 304a slides a short distance on the inner wall of the rotating sleeve 301c, there is a certain buffer zone, and the upper annular groove 304b or the lower annular groove 304c and one of the vertical grooves 301c-1 can still be aligned, which can avoid the impact caused by the change of water pressure and cause damage to the pipeline. During the movement of the guide sleeve 304a, the liquid pressure is relatively balanced, and there is no need to stop cleaning to control the sliding of the guide sleeve 304a. At the same time, due to L1-Q1≥L2, And L2≥Q1, therefore, by controlling the sliding distance of the guide sleeve 304a, the alignment of the upper annular groove 304b and / or the lower annular groove 304c and the vertical grooves 301c-1 at different positions can be changed, so that different flat-sweeping nozzles 301e can be switched and used, and the cleaning position can be changed. During the continuous sliding of the guide sleeve 304a, there will always be an upper annular groove 304b or a lower annular groove 304c aligned with one of the vertical grooves 301c-1, or the upper annular groove 304b and the lower annular groove 304c are aligned with two adjacent vertical grooves 301c-1 at the same time, so as to ensure that the size of the liquid flow cross-section is in a relatively constant state, thereby avoiding the situation in which the pipeline is damaged due to excessive changes in water pressure during the continuous sliding of the guide sleeve 304a, and there is no need to stop the cleaning operation when switching the flat-sweeping nozzles 301e at different positions.

[0064] Furthermore, the lifting assembly 303 includes a second motor 303a fixed at the end of the upper sleeve 301a, and a threaded rod 303b fixed on the output shaft of the second motor 303a, the outer wall of the threaded rod 303b is threadedly connected with a threaded sleeve 303c, and also includes a limiting guide rod 303d fixed at the end of the threaded sleeve 303c; in this embodiment, a sealing structure is provided at one end of the upper sleeve 301a close to the second motor 303a, which is used to seal the threaded rod 303b and the upper sleeve 301a, one end of the threaded rod 303b penetrates into the upper sleeve 301a, and the outer wall of the threaded sleeve 303c is provided with two symmetrically arranged limiting guide rods 303d.

[0065] Preferably, a limiting groove 301a-1 is provided on the inner wall of the upper sleeve 301a. In this embodiment, the inner wall of the limiting groove 301a-1 and the end of the limiting guide rod 303d are slidably connected to limit the movement of the threaded sleeve 303c.

[0066] The rest of the structure is the same as that of Example 1.

[0067] The switching process is illustrated with an example in combination with the working principle. The initial state is set as that the lower annular groove 304c and the uppermost vertical groove 301c-1 of the rotating sleeve 301c are in an aligned state. The upper annular groove 304b is blocked by the outer wall of the rotating sleeve 301c at this time. At this time, the flow path of the liquid is to enter the guide sleeve 304a from the upper sleeve 301a, and then flow into the lower annular groove 304c from the guide sleeve 304a through the second through hole 304c-1. The liquid in the lower annular groove 304c enters the corresponding liquid collecting cover 301d through the vertical groove 301c-1 aligned with it, and finally is sprayed out through the flat sweeping nozzle 301e on the liquid collecting cover 301d. At this time, the rotating sleeve 301c can be controlled to rotate by the rotating component 302 to change the cleaning angle of the flat sweeping nozzle 301e. The annular design of the lower annular groove 304c can maintain the flow of liquid and achieve cleaning at different angles.

[0068] When the flat-sweeping nozzle 301e of different parts is switched for cleaning, the threaded rod 303b is rotated by the operation of the second motor 303a. Under the limiting effect of the limiting groove 301a-1 and the limiting guide rod 303d on the threaded sleeve 303c, the threaded sleeve 303c will slide on the outer wall of the threaded rod 303b, so that the guide sleeve 304a slides down on the inner wall of the rotating sleeve 301c. During the sliding process, due to Q1>Q2, when the guide sleeve 304a slides on the inner wall of the rotating sleeve 301c, there is a certain buffer zone. During this process, the lower annular groove 304c can still be completely aligned with the vertical groove 301c-1. When the lower annular groove 304c is about to be misaligned with the vertical groove 301c-1, the upper annular groove 304b is about to be gradually aligned with the vertical groove 301c-1 due to sliding. Therefore, when the lower annular groove 304c and the vertical groove 301c-1 are misaligned, a partial area of ​​the upper annular groove 304b is aligned with the vertical groove 301c-1. At this time, the liquid flow cross-section remains unchanged, and the water pressure can be maintained in a relatively constant state until the upper annular groove 304b and the vertical groove 301c-1 are completely aligned. The lower annular groove 304c and the vertical groove 301c-1 are in a completely misaligned state, and the lower annular groove 304c will be blocked by the rotating sleeve 301c. At this time, liquid is supplied through the upper annular groove 304b.

[0069] By analogy, as the sliding distance of the guide sleeve 304a increases, the upper annular groove 304b will gradually be misaligned with the vertical groove 301c-1, and at the same time, the lower annular groove 304c will gradually align with the next vertical groove 301c-1, until the upper annular groove 304b and the upper vertical groove 301c-1 are completely misaligned, the lower annular groove 304c will be completely aligned with the next vertical groove 301c-1, thereby realizing the switching of the flat-sweeping nozzle 301e. During the switching process, the influence of water pressure changes can be avoided, thereby improving the service life of the pipeline. At the same time, during and after the switching process, the flat-sweeping nozzle 301e can be rotated in conjunction with the operation of the rotating component 302 to achieve multi-angle and multi-position cleaning and avoid the generation of cleaning dead corners.

[0070] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, the cleaning mechanism 300 also includes a bottom cleaning member 305 rotatably arranged at the end of the rotating sleeve 301c; in this embodiment, the bottom cleaning member 305 can clean the bottom surface of the non-ribbed water tank body 102.

[0071] The bottom cleaning component 305 includes a rotating sleeve 305a rotatably arranged at the end of the rotating sleeve 301c, and a flushing head 305b fixedly arranged at the end of the rotating sleeve 305a, and also includes an inclined hole 305c arranged in the flushing head 305b, and a boss 305d is arranged at the top of the flushing head 305b. In this embodiment, the rotating sleeve 305a can rotate at the end of the rotating sleeve 301c, and a plurality of inclined holes 305c are arranged, and are evenly spaced and circumferentially distributed in the flushing head 305b. The boss 305d is arranged at the center of the flushing head 305b, which is located at the center of the rotating sleeve 305a.

[0072] Specifically, the one-way flow member 304d includes a support sleeve 304d-1 fixedly arranged at the end of the guide sleeve 304a, and a slide rod 304d-2 slidably arranged on the inner wall of the support sleeve 304d-1, a sealing plug 304d-3 is fixedly installed at the end of the slide rod 304d-2, and a head 304d-4 is fixedly installed at the other end of the slide rod 304d-2, and also includes a spring 304d-5 sleeved on the outer wall of the slide rod 304d-2. The inner wall of the guide sleeve 304a is provided with a spring 304d-5 for accommodating the sealing plug 304d-3. Cavity 304a-1. In the present embodiment, the slide rod 304d-2 can slide on the inner wall of the support sleeve 304d-1. The sealing plug 304d-3 is disposed in the accommodating cavity 304a-1. The elastic force of the spring 304d-5 can push the top head 304d-4 so that the top head 304d-4 has a tendency to move away from the accommodating cavity 304a-1. Through the elastic force of the spring 304d-5, the sealing plug 304d-3 can maintain the sealing of the inner wall of the accommodating cavity 304a-1.

[0073] The rest of the structure is the same as that of Example 2.

[0074] The guide sleeve 304a is slid by the lifting assembly 303 so that the upper annular groove 304b is aligned with the lowest vertical groove 301c-1. At this time, the lower annular groove 304c is in a state of being blocked by the rotating sleeve 301c. After cleaning the inner wall surface of the non-tensioned water tank body 102, the guide sleeve 304a is controlled to continue to slide down. When the upper annular groove 304b and the vertical groove 301c-1 are about to be misaligned, the top head 304d-4 and the boss 305d just collide with each other. When the guide sleeve 304a continues to slide down, the pressure will compress the spring 304d-5, and the sealing plug 304d-3 will open. The upper annular groove 304b and the vertical groove 301c-1 are misaligned. 04b and the vertical groove 301c-1 are misaligned, and the cross-sectional area of ​​the liquid flow is reduced. By opening the sealing plug 304d-3, the area of ​​the flow channel can be increased to protect the pipeline. When the guide sleeve 304a slides to be completely misaligned with the vertical groove 301c-1, the liquid is completely sprayed out through the bottom cleaning piece 305. With the rotation of the rotating component 302, the bottom surface of the non-tensioned water tank body 102 can be cleaned. When the liquid flows through the inclined hole 305c, a rotational thrust is generated due to the inclined angle of the liquid injection. At this time, the rotating sleeve 305a can be rotated by the flow of the fluid, and there is no need for the rotating component 302 to rotate the bottom cleaning piece 305.

[0075] In summary, it is convenient to clean the inner wall and the bottom wall of the bottom cleaning part 305, and by rotating and coordinating the cleaning positions, all-round cleaning without dead angles can be achieved.

[0076] Example 4, reference Figure 1 to Figure 7 , which is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adaptive automatic cleaning method for a non-tensioned water tank, including: draining the water in the non-tensioned water tank body 102; controlling the flat-sweeping nozzle 301e to perform rotational cleaning through the rotating component 302; lifting and lowering the guide component 304 through the lifting component 303 to continuously change the cleaning position; after the inner wall of the non-tensioned water tank body 102 is cleaned around, the guide component 304 is lowered to the lowest position through the lifting component 303, and at this time, the bottom cleaning component 305 works to clean the bottom wall of the non-tensioned water tank body 102.

[0077] The rest of the structure is the same as that of Example 3.

[0078] When in use, the lifting component 303 controls the sliding of the guide component 304 to change the cleaning height. Combined with the rotation of the rotating component 302, the angle and height can be changed to increase the cleaning range. When the lifting component 303 controls the guide component 304 to drop to the lowest point, the bottom cleaning component 305 can be used to rinse the bottom wall of the non-tensioned water tank body 102, thereby improving the cleaning effect and efficiency and covering a wide cleaning range.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
