[0036] In one embodiment of the present invention, in order to ensure that the water intake shell 9 can smoothly take water when it rotates to the bottom, a groove is also provided on the inner side of the box body 1 so that the water flow can move along the groove into the water intake shell 9, and the side of the opening of the water intake shell 9 in the rotating state is in a sealed state with the inner wall of the box body 1. In addition, according to the drawings of the specification Figure 1 As a reference, the water intake shell 9 rotates counterclockwise. The stage from when the water intake shell 9 leaves the liquid surface to when the real-time cleaning mechanism 300 rotates is the filtering stage. To ensure complete filtration during the filtering stage, the size of the space inside the water intake shell 9 needs to be controlled to ensure that the water is completely discharged after the filtration is completed in the above stage.

[0037] like Figure 1 As shown, as a preferred embodiment of the present invention, the directional transport mechanism 100 includes a fixing rod 7, a positioning column 8 and a water intake shell 9;

[0038] The fixing rod 7 is fixedly connected to the outer cylindrical surface of the longitudinal rotating shaft 5 at an equal angle;

[0039] The positioning column 8 is fixedly mounted on the end of the fixing rod 7 and moves synchronously with the fixing rod 7;

[0040] The water intake shell 9 is closed at one end and eccentrically arranged on the positioning column 8 so as to facilitate translation when subjected to force;

[0041] A sealing gasket 11 is installed on the inner side of the bottom of each water intake shell 9 for filtering the wastewater in translation.

[0042] In one embodiment of the present invention, an external motor drives the longitudinal rotating shaft 5 to rotate along the casing 1, and the longitudinal rotating shaft 5 drives the fixing rods 7 and the positioning columns 8 at multiple positions to rotate synchronously, and the water intake shell 9 moves horizontally in the casing 1, and water is taken when the water intake shell 9 is below the liquid level.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown in FIG. 1 , as another preferred embodiment of the present invention, the liquid collecting and exporting mechanism 200 includes a sealing pad 11, a liquid infusion tube 12, a liquid infusion tube 2 13 and a drainage tube 14;

[0044] The sealing pad 11 is arranged in multiple sections, which are respectively located on both sides of the positioning column 8. The interior of the sealing pad 11 is a hollow structure, and the adjacent sealing pads 11 are in a connected state through an external infusion tube 13;

[0045] The sealing gasket 11 is also connected to the water intake shell 9 through an infusion tube 12 to collect the filtered water flow, and a hole is opened on the outside of the sealing gasket 11, which is connected to the drainage pipe 14 at the bottom of the box body 1.

[0046] In one embodiment of the present invention, after the water intake shell 9 leaves the liquid surface, it begins to be filtered by the arranged filter layer 10. The filtered water flows along the infusion pipe 12 into the sealing gasket 11, and is discharged to the bottom along the infusion pipe 2 13, and finally discharged through the arranged drainage pipe 14.

[0047] like Figure 5 As shown, as another preferred embodiment of the present invention, the real-time cleaning mechanism 300 includes a transverse rotating shaft 17, a driving gear 20, a single-side tooth plate 21, an elastic support member 22, a connecting rod 23 and a scraper rod 24;

[0048] The transverse rotating shaft 17 is rotatably mounted in the housing 16, and a driving gear 20 is fixedly mounted on the transverse rotating shaft 17, and a smooth portion is partially provided on the driving gear 20;

[0049] The bottom of the driving gear 20 is meshed with a single-sided tooth plate 21, and the single-sided tooth plate 21 is connected to an elastic support member 22 arranged in the housing 16;

[0050] A connecting rod 23 is installed at the bottom end of the single-sided tooth plate 21 , and a scraping rod 24 is installed at the bottom of the connecting rod 23 .

[0051] In one embodiment of the present invention, when the transverse rotating shaft 17 rotates along the outer shell 16, the transverse rotating shaft 17 drives the driving gear 20 arranged at the end to rotate synchronously. Since the driving gear 20 is engaged with the single-sided tooth plate 21, the single-sided tooth plate 21, the connecting rod 23 and the scraper rod 24 can be pushed to move along the surface of the filter layer 10 to clean the debris attached to the filter layer 10, and the elastic support member 22 arranged in combination makes the single-sided tooth plate 21 reciprocate in the horizontal longitudinal direction, thereby realizing continuous cleaning of the filter layer 10.

[0052] like Figure 5 As shown, as another preferred embodiment of the present invention, the end of the longitudinal shaft 5 is located in the housing 16 and is equipped with a bevel gear 18, and one end of the transverse shaft 17 is equipped with a bevel gear 2 19, and the bevel gear 2 19 is in meshing state with the bevel gear 18;

[0053] The longitudinal rotating shaft 5 is connected to the external motor shaft end through a coupling, so that the transverse rotating shaft 17 can be driven to rotate synchronously when the longitudinal rotating shaft 5 rotates through the provided bevel gear 18 and bevel gear 2 19.

[0054] In one embodiment of the present invention, the external motor is also electrically connected to the operating platform 15 arranged on the box body 1. By controlling the operating platform 15, the external motor is put into operation. The external motor drives the longitudinal rotating shaft 5 to rotate along the box body 1 through the coupling. The longitudinal rotating shaft 5 drives the bevel gear 18 at the end to rotate synchronously. Since the bevel gear 18 is in a meshing state with the bevel gear 2 19, it can drive the transverse rotating shaft 17 to rotate along the outer shell 16.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, as another preferred embodiment of the present invention, a liquid level meter 6 is installed in the box body 1, and a solenoid valve 4 is arranged on the filling pipe 2. The solenoid valve 4 and the liquid level meter 6 are electrically connected to the operating platform 15 installed on the top of the box body 1, so as to control the water inlet process according to the liquid level inside the box body 1.

[0056] In one embodiment of the present invention, in order to prevent the liquid level from being too high after the wastewater enters the box body 1, the arranged liquid level meter 6 can monitor the internal liquid level in real time, and transmit the monitoring result to the operating platform 15. The operating platform 15 controls the opening size of the solenoid valve 4 and adjusts the height of the liquid level inside the box body 1 in real time to keep it within a controllable range.

[0057] In summary, wastewater is added to the inside of the box body 1 along the filling pipe 2 and the diversion pipe 3, and the height of the liquid level is monitored in real time by the liquid level meter 6. By controlling the operating platform 15, the external motor is operated, and the external motor drives the longitudinal shaft 5 to rotate along the box body 1 through the coupling, and the longitudinal shaft 5 drives the fixed rods 7 and the positioning columns 8 at multiple positions to rotate synchronously, and the water intake shell 9 moves horizontally in the box body 1. When the water intake shell 9 is below the liquid level, water is taken. After the water intake shell 9 is separated from the liquid surface, the wastewater is filtered by the arranged filter layer 10, and the filtered water flow is introduced into the sealing gasket 11 along the infusion pipe 12, and is discharged to the bottom along the infusion pipe 2 13, and finally discharged through the arranged drain pipe 14. When the longitudinal shaft 5 rotates to a horizontal state, the longitudinal shaft 5 drives the bevel gear 18 at the end to rotate synchronously. Since the bevel gear 18 and the bevel gear 2 1 9 is in meshing state, which can drive the transverse rotating shaft 17 to rotate along the shell 16, and the driving gear 20 rotates synchronously therewith. Since the driving gear 20 is meshing with the single-sided tooth plate 21, the single-sided tooth plate 21, the connecting rod 23 and the scraper rod 24 can be pushed to move along the surface of the filter layer 10 to clean the debris attached to the filter layer 10, and the elastic support member 22 arranged in combination makes the single-sided tooth plate 21 reciprocate in the horizontal longitudinal direction, thereby realizing continuous cleaning of the filter layer 10, and the cleared debris can be stored in a storage box independently arranged in the shell 16; the device does not need to interrupt work when treating wastewater, can realize continuous treatment work, ensure the treatment efficiency, and it is not easy for debris to accumulate inside. The inside can be cleaned in real time during the treatment process to ensure the quality of wastewater treatment, and there is no need to manually disassemble the device for internal cleaning, which greatly reduces the difficulty of cleaning.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
