[0022] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0023] As Figures 1 to 7 shown, an automatic cleaning device for a filtration tank in a water supply plant according to an embodiment of the present invention is shown. Please refer specifically to Figure 1 , Figure 2 , Figure 3 . It includes a position adjusting assembly 7. A mounting top plate 1000 is provided at the top of the position adjusting assembly 7. A pool body 900 is provided at the bottom of the mounting top plate 1000. A filter screen 800 is fixedly connected to the front of the pool body 900. The bottom of the position adjusting assembly 7 is connected to a second motor 6. The output shaft of the second motor 6 is connected to an outer frame assembly 2. A first adjusting assembly 3 is provided inside the outer frame assembly 2. The center of the bottom of the outer frame assembly 2 is connected to a second adjusting assembly 4. Cleaning assemblies 5 are provided at the four peripheries of the bottom of the outer frame assembly 2. The position adjusting assembly 7 drives the cleaning assemblies 5 to move, and the second motor 6 drives the cleaning assemblies 5 to rotate to clean the filter screen 800.

[0024] Please refer specifically to Figure 1, the position adjustment component 7 includes a fixed mounting base 701, the fixed mounting base 701 is fixedly connected to the bottom of the mounting top plate 1000, one end of the fixed mounting base 701 is fixedly connected to a first electric push rod 702, the output shaft of the first electric push rod 702 is fixedly connected to a fourth mounting base 703, the fourth mounting base 703 is slidably connected to the bottom of the mounting top plate 1000, the front of the fourth mounting base 703 is fixedly connected to a second electric push rod 704, the output shaft of the second electric push rod 704 is fixedly connected to a fifth mounting base 705, the fifth mounting base 705 is slidably connected to the bottom of the mounting top plate 1000, the bottom of the fifth mounting base 705 is fixedly connected to a third electric push rod 706, and the output shaft of the third electric push rod 706 is fixedly connected to the top of the second motor 6.

[0025] Specifically, telescopic rods for adjusting the height of the mounting top plate 1000 are installed on both sides of the bottom of the mounting top plate 1000. When the pool body 900 is normally supplied with water, the telescopic rods of the mounting top plate 1000 drive the position adjustment component 7 to rise until the bottom of the cleaning component 5 is above the water level. When the filter screen 800 and the pool body 900 need to be cleaned, the telescopic rods of the mounting top plate 1000 are started to drive the position adjustment component 7 to descend to the lowest position, and the position adjustment component 7 drives the cleaning component 5 to clean the pool body 900 and the filter screen 800. The first electric push rod 702 drives the fourth mounting base 703 to move horizontally, thereby driving the fifth mounting base 705 and the cleaning component 5 to move horizontally. The third electric push rod 706 drives the cleaning component 5 to move up and down, so that the cleaning component 5 can fully clean the filter screen 800. The second electric push rod 704 drives the fifth mounting base 705 to move back and forth, driving the cleaning component 5 to clean the side wall of the pool body 900. Among them, the models of the first electric push rod 702, the second electric push rod 704, and the third electric push rod 706 are all ML16, which have waterproof properties and can prevent foreign objects and dust from invading. This device is long-term at the top of the water surface to prevent its internal structure from being damaged by the humid environment.

[0026] Please refer specifically to Figure 4 , the first adjustment component 3 includes an adjustment disk 302. Arc-shaped grooves 303 are opened on the periphery of the top of the adjustment disk 302, and the center of the top of the adjustment disk 302 is fixedly connected to a first motor 301. The output shaft of the first motor 301 is fixedly connected to the center of the top of the adjustment disk 302.

[0027] Specifically, starting the first motor 301 to drive the adjustment disk 302 to rotate can change the position of the arc-shaped groove 303.

[0028] Please refer specifically to Figure 2 , Figure 3, the outer frame assembly 2 includes a limiting outer frame 202. A motor box 201 is fixedly connected to the top of the limiting outer frame 202. Both the motor box 201 and the limiting outer frame 202 are hollow structures. The top of the motor box 201 is fixedly connected to the output shaft of the second motor 6. The outer side of the output shaft of the second motor 6 is rotatably connected to a mounting frame 1 through a bearing. Limiting grooves 204 are opened around the bottom of the limiting outer frame 202.

[0029] Specifically, the motor box 201 protects the first motor 301, and sealing rings are provided at the connection parts for protection to prevent the internal structure from being damaged by a humid environment. A protective box is arranged outside the second motor 6, and a sealing ring is arranged at the connection part between the protective box and the output shaft of the second motor 6. The top of the protective box is fixedly connected to the bottom of the output shaft of the third electric push rod 706 to prevent the internal structure from being damaged by a humid environment; the limiting outer frame 202 protects the adjusting disc 302. Starting the second motor 6 drives the mounting frame 1 to rotate, thereby driving the outer frame assembly 2 and the first adjusting assembly 3 to rotate synchronously. Among them, to avoid the winding of the wiring cable of the first motor 301, a cable rotary joint is used for the wiring cable of the first motor 301. When the first motor 301 rotates itself, the wiring cable does not rotate, and the wiring cable of the first motor 301 passes through the motor box 201, is built inside the mounting frame 1, and the wiring cable exits from the top of the mounting frame 1, and the mounting frame 1 itself does not rotate.

[0030] Please refer specifically to Figure 2 , Figure 3 , Figure 5 , the cleaning assembly 5 includes a T-shaped limiting rod 506. The outer diameter of the bottom of the T-shaped limiting rod 506 has a clearance fit with the widths of the limiting groove 204 and the arc-shaped groove 303. An activity groove 203 is opened at the top inside the limiting outer frame 202. A third mounting seat 503 is fixedly connected to the bottom of the T-shaped limiting rod 506. A support rod 502 is arranged at the bottom of the third mounting seat 503. The bottom of the support rod 502 is connected to a cleaning brush assembly 501.

[0031] Specifically, the outer diameter of the top of the T-shaped limiting rod 506 is larger than that of the bottom of the T-shaped limiting rod 506, and the top of the T-shaped limiting rod 506 is located at the top of the adjusting disc 302 and moves in the moving groove 203. When the first motor 301 is started, the arc-shaped groove 303 and the limiting groove 204 jointly limit the T-shaped limiting rod 506. The position of the limiting groove 204 remains unchanged, and the position of the arc-shaped groove 303 changes as the adjusting disc 302 rotates. Thus, the overlapping position of the arc-shaped groove 303 and the limiting groove 204 moves along the limiting groove 204. When the adjusting disc 302 rotates clockwise, the T-shaped limiting rod 506 moves toward the side close to the second adjusting assembly 4 in the limiting groove 204. When the adjusting disc 302 rotates counterclockwise, the T-shaped limiting rod 506 moves toward the side away from the second adjusting assembly 4 in the limiting groove 204. Since the middle part of the filter net 800 is frequently impacted by water, deformation occurs in the middle part and bulges toward the front, that is, the tension degrees of different positions of the filter net 800 are different. When encountering the deformed position, it is necessary to adjust the distance between different cleaning assemblies 5 to expand and fit the surface of the filter net, so as to clean the filter net more effectively. When the second electric push rod 704 moves to the longest, the cleaning assembly 5 is located on the side closest to the limiting groove 204 inside the limiting groove 204. This is the state of cleaning the filter net 800. At this time, the cleaning brush assembly 501 can just clean the inner surface and filter holes of the filter net 800.

[0032] Please refer particularly to Figure 6 , the cleaning brush assembly 501 includes a second mounting seat 5014. The second mounting seat 5014 is a hollow structure. A limiting arc plate 5012 is slidably connected inside the second mounting seat 5014. A brush body 5011 is fixedly connected to the side of the limiting arc plate 5012 away from the second adjusting assembly 4. A spring 5013 is fixedly connected to the side of the limiting arc plate 5012 close to the second adjusting assembly 4. A square groove is opened on the side of the second mounting seat 5014 away from the second adjusting assembly 4. The square groove of the second mounting seat 5014 is in clearance fit with the outer dimension of the side of the brush body 5011 close to the second adjusting assembly 4.

[0033] Specifically, the brush body 5011 includes a base and bristles. The bristles of the brush body 5011 can clean the filter holes and the back of the filter net 800 during rotation. When the deformation amount of the filter net 800 at the deformed position is uneven, the spring 5013 can appropriately adjust the distance between the brush body 5011 and the filter net 800. At the same time, during the cleaning process, the spring 5013 can offset part of the pressure between the bristles of the brush body 5011 and the filter net 800, avoiding damage to the bristles of the brush body 5011 and deformation of the filter net caused by the rotating brush body 5011 being squeezed.

[0034] Please refer particularly to Figure 6 、 Figure 7, the second adjustment component 4 includes an electric push rod 407. The top of the electric push rod 407 is fixedly connected to the center of the bottom of the support rod 502. The output shaft of the electric push rod 407 is fixedly connected with a limit disk 401. First moving holes 402 are formed in the circumferences of the top of the limit disk 401. A T-shaped rod 405 is slidably connected to the inner side of the first moving hole 402. A pull plate 403 is fixedly connected to the bottom of the T-shaped rod 405. A first mounting seat 404 is fixedly connected to the side of the pull plate 403 away from the electric push rod 407. A round rod 406 is fixedly connected to the side of the first mounting seat 404 away from the electric push rod 407.

[0035] Specifically, the electric push rod 407 uses a remote-controlled, power-built-in electric push rod without external wires. The model of the electric push rod 407 is ML16 to avoid damage to its internal structure in a humid environment.

[0036] Specifically, under the action of the second adjustment component 4, the cleaning component 5 has two states. The first state is parallel to the limit outer frame 202, which is the state of cleaning the filter screen 800. The cooperation of the cleaning component 5 with the outer frame component 2 and the first adjustment component 3 to clean the filter screen 800 is all in the first state. The second state is perpendicular to the limit outer frame 202, which is the state of cleaning the bottom wall of the pool body 900. The bottom wall of the pool body 900 is cleaned under the drive of the second motor 6, and the bristles of the brush body 5011 will not be damaged when approaching the back of the filter screen 800 and the front of the pool body 900, which can protect the bristles of the brush body 5011.

[0037] Please refer to Figure 7 , a drive block 504 is fixedly connected to the side of the support rod 502 close to the second adjustment component 4. A second moving hole 505 is formed in the front of the drive block 504. The drive block 504 is movably connected to the outside of the round rod 406.

[0038] Specifically, for the switching between the two states of the cleaning component 5, the second state is the initial state. In the initial state, the T-shaped limit rod 506 and the T-shaped rod 405 are respectively on the side closest to the center of the limit disk 401 in the limit groove 204 and the first moving hole 402. When it is necessary to switch to the first state, it is necessary to start the electric push rod 407 to extend the output shaft to push the limit disk 401 downward. Since the top of the T-shaped rod 405 is located on the top of the limit disk 401 and the outer diameter of the top of the T-shaped rod 405 is larger than the outer diameter of the bottom of the T-shaped rod 405, the bottom height of the T-shaped rod 405 is the same as that of the limit disk 401, and the outer diameter of the bottom of the T-shaped rod 405 has a clearance fit with the width of the first moving hole 402. When the limit disk 401 moves downward, it will drive the T-shaped rod 405, the pull plate 403, and the first mounting seat 404 to move downward synchronously, so that the first mounting seat 404 pulls the drive block 504 to turn downward, thereby causing the support rod 502 to drive the cleaning brush component 501 to turn away from the limit disk 401 until the cleaning brush component 501 and the support rod 502 are parallel to the limit outer frame 202 and change to the first state.

[0039] Please refer specifically to Figure 6 , the length of the limiting groove 204 and the length tolerance of the first moving hole 402 are matched.

[0040] Specifically, when the T-shaped limiting rod 506 moves to the outermost side in the limiting groove 204, the T-shaped rod 405 moves synchronously to the outermost side of the first moving hole 402. When the T-shaped limiting rod 506 moves to the innermost side in the limiting groove 204, the T-shaped rod 405 moves synchronously to the innermost side of the first moving hole 402, and the first moving hole 402 does not hinder the movement of the cleaning assembly 5.

[0041] Working principle When the pool body 900 is normally supplied with water, the telescopic rod of the installation top plate 1000 drives the position adjustment assembly 7 to rise until the bottom of the cleaning assembly 5 is above the water level. When the filter screen 800 and the pool body 900 need to be cleaned, the water supply is stopped, and the telescopic rod of the installation top plate 1000 is started to drive the position adjustment assembly 7 to descend to the lowest position, as Figure 1 shown. At this time, the position adjustment assembly 7 drives the cleaning assembly 5 to clean the pool body 900 and the filter screen 800: When the cleaning assembly 5 is in the first state, the second electric push rod 704 moves to the longest, and the cleaning assembly 5 is located on the innermost side of the limiting groove 204 and closest to the limiting groove 204, that is, in the state of cleaning the filter screen 800: When cleaning the filter screen 800, the first motor 301 is started. The position of the limiting groove 204 remains unchanged, and the position of the arc-shaped groove 303 changes as the adjustment disc 302 rotates. Therefore, the overlapping position of the arc-shaped groove 303 and the limiting groove 204 moves along the limiting groove 204. When the adjustment disc 302 rotates clockwise, the T-shaped limiting rod 506 moves towards the side close to the second adjustment assembly 4 in the limiting groove 204. When the adjustment disc 302 rotates counterclockwise, the T-shaped limiting rod 506 moves towards the side away from the second adjustment assembly 4 in the limiting groove 204, expanding the distance between the cleaning assemblies 5 and fitting the surface of the filter screen, so as to clean the filter screen more effectively. At the same time, the first electric push rod 702 drives the fourth mounting seat 703 to move horizontally, and the third electric push rod 706 drives the cleaning assembly 5 to move up and down, making the cleaning of the cleaning assembly 5 more comprehensive. During the cleaning process, the spring 5013 can offset part of the pressure of the bristles of the brush body 5011 on the filter screen 800; When the cleaning assembly 5 is in the second state, the third electric push rod 706 moves to the longest position, so that the bottom of the bristles of the brush body 5011 contacts the bottom of the pool body 900 and the bottom of the pool body 900 has a certain squeezing force on the bristles of the brush body 5011. At this time, the cleaning assembly 5 rotates driven by the second motor 6 to peel off the sediment attached to the bottom. The first electric push rod 702 pushes the fourth mounting seat 703 to move left and right, and the second electric push rod 704 pushes the fifth mounting seat 705 to move back and forth to clean the bottom of the pool body 900 comprehensively, which is convenient for cleaning during backwashing; After the cleaning attachments on the pool body 900 and the filter net 800 are peeled off, backwashing is carried out. At this time, the telescopic rod of the installation top plate 1000 is started to drive the position adjustment assembly 7 to rise until the bottom of the cleaning assembly 5 is above the water level, and then the water is flushed from the filter net 800 towards the pool body 900, so as to remove the peeled cleaning attachments and complete the cleaning work.

[0042] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
