[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 As Figures 1 - 10 shown, the present invention discloses a water supply device for water body pretreatment, including an input pipeline 2 connected to one end of a multi-stage treatment tank 1, an output pipeline 3 connected to the other end of the multi-stage treatment tank 1, a liquid separation mechanism 4 arranged on one side of the multi-stage treatment tank 1, one end of the output pipeline 3 far from the multi-stage treatment tank 1 is connected to one end of the liquid separation mechanism 4, a scratching mechanism 5 is arranged inside the multi-stage treatment tank 1, a decontamination mechanism 6 is arranged on the other side of the multi-stage treatment tank 1, the liquid separation mechanism 4 provides the driving force for scratching for the scratching mechanism 5 through water pressure, and the liquid separation mechanism 4 provides the adsorption force for removing sewage for the decontamination mechanism 6 through water pressure. It should be noted that the external water supply can be transported to the inside of the multi-stage treatment tank 1 through the input pipeline 2 for multi-stage filtration operations. When the multi-stage treatment tank 1 has performed multi-stage filtration operations on the water supply, the pretreatment operation of the water supply is completed, and then the pretreated water supply is transported to the liquid separation mechanism 4 through the output pipeline 3, and the liquid separation mechanism 4 transports the pretreated water supply to the water supply device again. It should be noted that the liquid separation mechanism 4 provides the driving force for scratching for the scratching mechanism 5 through water pressure, so that the scratching mechanism 5 does not require an additional power source, reducing the equipment composition of the water body pretreatment mechanism and the energy consumption of the water body pretreatment mechanism for treating water. Moreover, the liquid separation mechanism 4 provides the adsorption force for removing sewage for the decontamination mechanism 6 through water pressure, so that the decontamination mechanism 6 can automatically remove the impurities remaining after filtration in the multi-stage treatment tank 1, ensuring the filtration efficiency of the multi-stage treatment tank 1.

[0020] Example 2 As Figures 1 - 10 shown, the multi-stage treatment tank 1 includes a treatment tank body 11. Inside the treatment tank body 11, a primary filtration chamber 12, a secondary filtration chamber 13, a tertiary filtration chamber 14, and a liquid collection chamber 15 are successively provided. Filter cartridges 17 are arranged inside the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14. A dirt collection groove 19 is provided at the bottom end of the filter cartridge 17. It should be noted that the filter cartridges 17 arranged inside the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14 can be of different specifications and different types. For example, the filter cartridge 17 inside the primary filtration chamber 12 can be set as a sieve to filter out larger particulate matters in the water supply. Then, the aperture of the sieve is successively reduced in the secondary filtration chamber 13 and the tertiary filtration chamber 14. An activated carbon adsorption layer can also be provided inside the tertiary filtration chamber 14 to further treat the water supply. One end of the filter cartridge 17 is fixedly connected to a docking end cover 111, and a docking pipe 112 is fixedly connected to one side of the docking end cover 111. Communication grooves 18 are provided inside the secondary filtration chamber 13, the tertiary filtration chamber 14, and the liquid collection chamber 15, and the communication grooves 18 are in fit with the docking pipe 112. In this way, the water supply in the filter cartridge 17 inside the primary filtration chamber 12 can enter the inside of the secondary filtration chamber 13 through the docking end cover 111 and the docking pipe 112, and so on. The water supply in the secondary filtration chamber 13 enters the tertiary filtration chamber 14, the water supply in the tertiary filtration chamber 14 enters the liquid collection chamber 15, and the liquid collection chamber 15 then conveys the water supply into the inside of the output pipe 3.

[0021] Inside the output pipe 3, an infusion groove 31 is provided. Inside the infusion groove 31, a rotatable liquid separation cylinder 32 is arranged. A liquid separation channel 33 is provided inside the liquid separation cylinder 32. Two groups of liquid separation docking grooves 34 are provided at one end of the liquid separation cylinder 32 away from the infusion groove 31. An external pipe 16 is provided at one end of the treatment tank body 11 close to the output pipe 3, and the external pipe 16 is in fit with the output pipe 3. In this way, the output pipe 3 can be hermetically connected to the external pipe 16. The water supply pretreated by the treatment tank body 11 can enter the inside of the infusion groove 31 through the external pipe 16, realizing the conveying function of the water supply. And since a rotatable liquid separation cylinder 32 is arranged inside the infusion groove 31 and a liquid separation channel 33 is provided inside the liquid separation cylinder 32, finally, the water supply inside the infusion groove 31 will enter the liquid separation channel 33 inside the liquid separation cylinder 32.

[0022] As Figures 1 - 5As shown, the liquid separation mechanism 4 includes a liquid separation tank 41. Inside the liquid separation tank 41, there is a liquid separation plate 42. The liquid separation plate 42 divides the inner cavity of the liquid separation tank 41 into two pressure chambers. On both sides of the liquid separation tank 41, there are a first pipeline 43 and a second pipeline 44. The two ends of the two groups of liquid separation docking grooves 34 far from the liquid separation cylinder 32 are respectively arranged on both sides of the inner cavity of the liquid separation tank 41. Inside both the first pipeline 43 and the second pipeline 44, there are solenoid valves to Figure 5 take Figure 5 as an example. The liquid separation docking grooves 34 at one end of the liquid separation tank 41 are divided into the upper liquid separation docking groove 34 and the lower liquid separation docking groove 34. When the liquid separation channel 33 inside the liquid separation cylinder 32 is docked with the upper liquid separation docking groove 34, the water supply in the liquid separation channel 33 inside the liquid separation cylinder 32 will enter the upper cavity of the liquid separation plate 42 through the upper liquid separation docking groove 34 and continuously concentrate in the upper cavity of the liquid separation plate 42. At this time, the solenoid valve inside the second pipeline 44 can be closed, and the solenoid valve inside the first pipeline 43 can be opened. In this way, the liquid separation plate 42 will move downward in the inner cavity of the liquid separation tank 41, and the water supply at the bottom of the liquid separation plate 42 will be extruded from the first pipeline 43. Both the first pipeline 43 and the second pipeline 44 can be directly connected to the corresponding water supply equipment. In this way, the first pipeline 43 can transport the pre-treated water supply to the water supply equipment.

[0023] When the liquid separation channel 33 inside the liquid separation cylinder 32 is docked with the lower liquid separation docking groove 34, the water supply in the liquid separation channel 33 inside the liquid separation cylinder 32 will enter the lower cavity of the liquid separation plate 42 through the lower liquid separation docking groove 34 and continuously concentrate in the lower cavity of the liquid separation plate 42. At this time, the solenoid valve inside the second pipeline 44 can be opened, and the solenoid valve inside the first pipeline 43 can be closed. In this way, the liquid separation plate 42 will move upward in the inner cavity of the liquid separation tank 41, and the water supply at the top of the liquid separation plate 42 will be extruded from the second pipeline 44. Both the first pipeline 43 and the second pipeline 44 can be directly connected to the corresponding water supply equipment. In this way, the second pipeline 44 can transport the pre-treated water supply to the water supply equipment.

[0024] Control terminals for opening and closing the solenoid valves inside the first pipeline 43 and the second pipeline 44 can be arranged at a position inside the infusion tank 31 close to the liquid separation cylinder 32. When the liquid separation channel 33 inside the liquid separation cylinder 32 corresponds to the upper liquid separation docking groove 34, the control terminal of the solenoid valve inside the first pipeline 43 is started, and at the same time, the control terminal of the solenoid valve inside the second pipeline 44 is closed. When the liquid separation channel 33 inside the liquid separation cylinder 32 corresponds to the lower liquid separation docking groove 34, the control terminal of the solenoid valve inside the first pipeline 43 is closed, and at the same time, the control terminal of the solenoid valve inside the second pipeline 44 is opened. The control terminals of the solenoid valves inside the first pipeline 43 and the second pipeline 44 are adaptively selected by those skilled in the art according to the specific situation of the position inside the infusion tank 31 close to the liquid separation cylinder 32, as long as it can accurately open and close the solenoid valves inside the first pipeline 43 and the second pipeline 44.

[0025] As Figure 5 、 Figure 6 and Figure 7 shown, a first driving rod 45 and a second driving rod 46 are respectively arranged on the inner side of the liquid separation box 41 near two groups of liquid separation docking grooves 34. A rotating shaft 35 is fixedly connected to the side surface of the liquid separation cylinder 32. Both the first driving rod 45 and the second driving rod 46 are meshed with the side surface of the rotating shaft 35. Both the first driving rod 45 and the second driving rod 46 are slidably arranged on the inner end surface of the liquid separation box 41. The end surfaces of the first driving rod 45 and the second driving rod 46 close to one end of the inner cavity of the liquid separation box 41 are both arranged as inclined surfaces, and the inclined surfaces are arranged oppositely. In this way, when the liquid separation plate 42 moves to the end surface position of the first driving rod 45 or the second driving rod 46, the liquid separation plate 42 can drive the first driving rod 45 or the second driving rod 46 by extrusion, so that the first driving rod 45 or the second driving rod 46 moves in the direction away from one end of the inner cavity of the liquid separation box 41. Therefore, a support spring is arranged at the end of the first driving rod 45 and the second driving rod 46 away from the inner cavity of the liquid separation box 41 to ensure that when the liquid separation plate 42 does not act on the end surface position of the first driving rod 45 or the second driving rod 46, the elastic force of the support spring can act on the first driving rod 45 and the second driving rod 46, so that the first driving rod 45 and the second driving rod 46 automatically rebound. As Figure 7 shown, the shapes of both the first driving rod 45 and the second driving rod 46 are Z-shaped, and both the first driving rod 45 and the second driving rod 46 are meshed with the side surface of the rotating shaft 35 near the rotating shaft 35. It should be noted that a ratchet is respectively connected to the side surface of the rotating shaft 35 near the first driving rod 45 and the second driving rod 46, that is, the meshing positions of the first driving rod 45 and the second driving rod 46 with the side surface of the rotating shaft 35 are staggered from each other. Taking the rotating shaft 35 in Figure 7 as an example, the first driving rod 45 can drive the rotating shaft 35 to rotate counterclockwise through the ratchet, and the second driving rod 46 can drive the rotating shaft 35 to rotate clockwise through the ratchet.

[0026] When the liquid separation plate 42 moves to the top position of the inner cavity of the liquid separation tank 41, that is, when the water supply at the top of the liquid separation plate 42 is completely discharged from the second pipeline 44, the liquid separation plate 42 can just drive the second driving rod 46 to move the second driving rod 46 towards one end away from the inner cavity of the liquid separation tank 41. At this time, the second driving rod 46 can drive the rotating shaft 35 to rotate clockwise through the ratchet wheel, that is, the liquid separation cylinder 32 can drive the liquid separation channel 33 inside it to rotate clockwise, so that the liquid separation channel 33 is switched from being docked with the liquid separation docking groove 34 at the bottom to being docked with the liquid separation docking groove 34 at the top. In this case, the solenoid valve inside the second pipeline 44 will automatically close, and at the same time, the solenoid valve inside the first pipeline 43 will automatically open. Then, the water supply inside the liquid separation channel 33 will enter the top cavity of the liquid separation plate 42 through the liquid separation docking groove 34 at the top, that is, the liquid separation plate 42 will move downward, and the water supply at the bottom of the liquid separation plate 42 will be extruded from the first pipeline 43.

[0027] When the liquid separation plate 42 moves to the bottom position of the inner cavity of the liquid separation tank 41, that is, when the water supply at the bottom of the liquid separation plate 42 is completely discharged from the first pipeline 43, the liquid separation plate 42 can just drive the first driving rod 45 to move the first driving rod 45 towards one end away from the inner cavity of the liquid separation tank 41. At this time, the first driving rod 45 can drive the rotating shaft 35 to rotate counterclockwise through the ratchet wheel, that is, the liquid separation cylinder 32 can drive the liquid separation channel 33 inside it to rotate counterclockwise, so that the liquid separation channel 33 is switched from being docked with the liquid separation docking groove 34 at the top to being docked with the liquid separation docking groove 34 at the bottom. In this case, the solenoid valve inside the second pipeline 44 will automatically open, and at the same time, the solenoid valve inside the first pipeline 43 will automatically close. Then, the water supply inside the liquid separation channel 33 will enter the bottom cavity of the liquid separation plate 42 through the liquid separation docking groove 34 at the bottom, that is, the liquid separation plate 42 will move upward, and the water supply at the top of the liquid separation plate 42 will be extruded from the second pipeline 44.

[0028] To sum up, the liquid separation plate 42 will move up and down repeatedly inside the liquid separation tank 41, and at the same time, the water supply will be discharged into the water supply device through the first pipeline 43 or the second pipeline 44.

[0029] Embodiment 3 As Figures 1 - 8As shown, the scraping mechanism 5 includes a scraping ring 51. A separation ring 52 is fixedly connected to the top of the scraping ring 51. A telescopic rod 54 is fixedly connected to one side of the scraping ring 51. Two built-in grooves 55 are provided inside the telescopic rod 54. A notch groove 53 is provided on the side of the separation ring 52 away from the telescopic rod 54. It should be noted that the scraping ring 51 should fit with the filter cylinder 17, so that the scraping ring 51 can slide freely along the side direction of the filter cylinder 17. One end of the telescopic rod 54 is fixedly connected to the surface of the liquid distribution plate 42. Since the filter cylinder 17 is arranged inside the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14, and the water supply enters the inside of the filter cylinder 17 from the outside of the filter cylinder 17 to achieve the filtration effect of the water supply. Therefore, when the filter cylinder 17 realizes the filtration effect, the sundries on the surface of the filter cylinder 17 will be adsorbed on the surface of the filter cylinder 17 under the action of the water supply flow direction. And one end of the telescopic rod 54 is fixedly connected to the surface of the liquid distribution plate 42. A telescopic groove 110 that fits with the telescopic rod 54 is provided on the surface of the treatment box body 11 near the telescopic rod 54. The liquid distribution plate 42 will move up and down repeatedly inside the liquid distribution box 41. So the liquid distribution plate 42 will drive the scraping ring 51 to move up and down along the side of the filter cylinder 17 through the telescopic rod 54, continuously scraping the side surface of the filter cylinder 17 to ensure the filtration effect of the filter cylinder 17. The separation ring 52 fixedly connected to the top of the scraping ring 51 fits with the sewage collection tank 19. When the scraping ring 51 moves into the inside of the sewage collection tank 19, it will scrape all the sundries on the side of the filter cylinder 17 into the inside of the sewage collection tank 19. At the same time, the separation ring 52 on the scraping ring 51 will form an annular thin tube with the sewage collection tank 19. When the built-in groove 55 generates an adsorption force, the built-in groove 55 can adsorb the sundries in the thin tube together. And the notch groove 53 can provide a flushing water source for the straw to ensure that the sundries in the sewage collection tank 19 can be completely adsorbed away. Since the scraping ring 51 scrapes along the side of the filter cylinder 17, the bottoms of the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14 can be set to be arc-shaped (set to be flat in the attached drawing, and the bottoms of the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14 are not limited to arc-shaped, and can also be set to be inverted triangles, as long as the sundries in the primary filtration chamber 12, the secondary filtration chamber 13, and the tertiary filtration chamber 14 can be gathered in the sewage collection tank 19. Specifically, it is adjusted adaptively by those skilled in the art according to the actual situation). It should be noted that one-way valves are provided inside the built-in grooves 55 to prevent the water supply containing sundries from flowing back.

[0030] Embodiment 4 As Figures 1 - 10As shown, the decontamination mechanism 6 includes a mechanism housing 61. Inside the cavity of the mechanism housing 61, there is a pressure piston 62. The pressure piston 62 is connected to the end face of the inner cavity of the mechanism housing 61 through a spring. Near the bottom position of the inner cavity of the mechanism housing 61 and close to the pressure piston 62, there is a moving block 63. On the side of the moving block 63 away from the pressure piston 62, there is a fixed connection with a moving rod 64. One end of the moving rod 64 away from the moving block 63 is fixedly connected to the telescopic rod 54. Since the liquid separation plate 42 drives the scraping ring 51 to move up and down along the side of the filter cylinder 17 through the telescopic rod 54, and one end of the moving rod 64 away from the moving block 63 is fixedly connected to the telescopic rod 54, the telescopic rod 54 can also drive the moving block 63 to freely slide along the inner cavity of the mechanism housing 61 through the moving rod 64. Additionally, it should be noted that a sewage channel is provided inside the moving block 63 and the moving rod 64, and the built-in groove 55 can transport sewage through the sewage channel to the cavity between the pressure piston 62 and the moving block 63; On the side of the moving block 63 close to the sewage channel, there is also a sewage discharge channel. A one-way valve is provided inside the sewage discharge channel to ensure that the sewage between the pressure piston 62 and the moving block 63 can be discharged through the one-way valve in the sewage discharge channel. The bottom of the mechanism housing 61 is designed with a hollow structure, and a sewage tank is provided at the bottom of the mechanism housing 61 to collect the sewage discharged by the moving block 63.

[0031] Take Figures 4 - 10 the spatial positions of the liquid separation mechanism 4, the scraping mechanism 5, and the decontamination mechanism 6 as an example. When the liquid separation plate 42 drives the scraping ring 51 to move downward along the side of the filter cylinder 17 through the telescopic rod 54, the moving block 63 will move downward in the inner cavity of the mechanism housing 61, causing the cavity between the moving block 63 and the pressure piston 62 to gradually increase and finally form a negative pressure. When the telescopic rod 54 moves to the lowest point, at the same time, the moving block 63 moves to the lowest point in the inner cavity of the mechanism housing 61, as shown in state A in the attachment Figure 9 . And it should be noted that at this time, the isolation ring 52 on the scraping ring 51 will form an annular thin tube with the sewage collection groove 19, and the negative pressure in the cavity between the moving block 63 and the pressure piston 62 reaches the maximum. Then, open the solenoid valve provided inside the built-in groove 55. In this way, the negative pressure cavity formed between the moving block 63 and the pressure piston 62 will adsorb the water supply containing impurities, that is, sewage, in the thin tube through the built-in groove 55. The sewage will enter the sewage channel through the built-in groove 55, and finally the sewage channel will transport the sewage to the cavity between the moving block 63 and the pressure piston 62, removing the sewage in the sewage collection groove 19.

[0032] When the liquid separation plate 42 drives the scraping ring 51 to move upward along the side of the filter cylinder 17 through the telescopic rod 54, close the solenoid valve inside the built-in groove 55. The moving block 63 will move upward in the inner cavity of the mechanism housing 61, as shown in the attachment Figure 9As shown in State B in the figure, the sewage between the extrusion moving block 63 and the pressure piston 62 is squeezed, and the sewage will be discharged through the sewage discharge channel on the moving block 63 under the action of pressure, and finally flows into the sewage tank, realizing the automatic adsorption and automatic discharge of the water supply containing sundries.

[0033] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
