[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when rainwater is collected and treated as a water resource, the rainwater is discharged into the sewage treatment tank through the water inlet at the top of the sewage treatment tank, and then the disinfectant is discharged through the feed port at the top of the sewage treatment tank to filter out impurities in the rainwater. At this time, the driving motor drives the driving rod to rotate, and the rotation of the driving rod drives the sleeve column to rotate. The two sets of stirring racks are driven by the sleeve column and the adjusting rack to put their stirring racks in an expanded state. Then, when the driving rod rotates, it can drive the set stirring rack to stir the sewage and disinfectant in the sewage treatment tank. The adjusting rack is driven to move by the set pushing electric cylinder. The movement of the adjusting rack can drive the sleeve column to move and then the sleeve column can slide on the driving rod. The sliding of the sleeve column can pull the articulated frame to move, so that the articulated frame drives the two sets of stirring racks to open and close at a larger angle, thereby improving the effect of mixing the sewage and the gel, and improving the efficiency of its sewage treatment.

[0017] In the present invention, after the sewage in the sewage treatment box is fully mixed with the disinfectant, the impurities will be at the bottom of the sewage tank in the sewage treatment box. At this time, the driving rod no longer rotates, and the adjusting frame moves downward. At this time, the resistance rod on the adjusting frame will contact the pressing part of the water valve, and then the water valve will be opened to enable the sewage in the upper layer of the sewage tank to be discharged outward through the water valve. At the same time, as the adjusting frame moves downward, the adjusting frame will drive the adjusting rack to move downward, and the downward movement of the adjusting rack drives the adjusting gear to rotate, thereby causing the moving rack to move upward. After the moving rack moves upward, it contacts the wedge-shaped frame on the outer wall of the moving frame, thereby driving the wedge-shaped frame to move the moving frame upward on the screening support frame until the wedge-shaped frame and the screening branch are aligned. When the wedge-shaped groove on the support frame is engaged, it stops, and when the mobile frame moves upward, it will pull the support rod upward, and the two sets of arc-shaped expansion plates arranged on the support rod will respectively pull the first set of rods and the second set of rods to rotate, and the expansion plates arranged on the first set of rods and the second set of rods will be expanded and in a parallel state. When the expansion plates are expanded, they will drive the folding and expansion frames connected thereto to expand and extend toward the outer wall of the screening support frame, and then synchronously drive the folding and expansion frames to expand. After the expansion, a baffle is formed between the expanded folding and expansion frames and is in a closed state. Then, when the water valve discharges the precipitated sewage in the sewage treatment tank, the sludge settled at the bottom can be effectively blocked by the expansion plates and folding and expansion frames to prevent the discharged sewage from containing sludge.

[0018] In the present invention, when rainwater enters the sewage treatment tank, the rainwater will contain large impurities such as branches and leaves that have not been filtered out, and such impurities entering the sewage treatment tank will affect the treatment of the sewage. The screening support frame is in the sewage tank, and the two groups of unfolding plates and folding unfolding frames arranged on the screening support frame are initially in a folded state, so that the larger impurities contained in the sewage can fall between the unfolding plates and the folding unfolding frames to be blocked, thereby facilitating the subsequent screening of sludge and larger impurities in the sewage.

[0019] When the folding and unfolding frame is unfolded on the screening support frame, the sliding block connected to the upper end of the folding and unfolding frame will move, and the clamping wheel arranged on the sliding block will contact the wedge-shaped pressure plate, and the wedge-shaped pressure plate will move downward under the drive of the elastic spring, and the downward movement of the wedge-shaped pressure plate will drive the moving block to move downward, and the moving block drives the rotating rod to move downward, and the clamping groove of the moving plate on the rotating rod will produce a limit rotation under the contact of the stopper on the screening support frame. At this time, the moving plate will drive the rotating rod to rotate, and the baffle on the rotating rod will rotate horizontally to cover the unfolding plate and the folding and unfolding frame arranged at the bottom, and the impurities on the unfolding plate and the folding and unfolding frame will be located between the baffle, the unfolding plate and the folding and unfolding frame. Through this arrangement, the impurities on the unfolding plate and the folding and unfolding frame will be blocked during the process of the water valve draining water outwards, so that when the sewage flows out, the impurities are prevented from flowing out together with the sewage.

[0020] In the present invention, after the sewage after sedimentation is discharged outwardly under the drive of the water valve, the screening support frame is driven by the arranged driving electric cylinder to move toward the direction of the sludge collecting tank as a whole. At this time, the scraper on the screening support frame will contact the sludge at the bottom of the sewage tank, and then scrape the sludge into the sludge collecting tank, so that the precipitated sludge can be in the sludge collecting tank, and the screening support frame will move to the filter plate above the sludge collecting tank, and the wedge frame clamped on the screening support frame will contact the elastic wedge frame. Then, driven by the elastic wedge-shaped retaining frame, the wedge-shaped frame is separated from the wedge-shaped groove. When the wedge-shaped frame is separated from the wedge-shaped groove, the movable frame is reset under the drive of the pressure spring, so that the unfolding plate and the folding unfolding frame are folded again. Impurities on the unfolding plate and the folding unfolding frame in the folded state will fall onto the filter plate, and then larger impurities can be screened by the filter plate. The operator can process the impurities remaining on the unfolding plate and the folding unfolding frame through the opening outside the sewage treatment tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A support rod 38 extends from the outer wall of the mobile frame 34, and two sets of arc-shaped expansion plates 39 are hingedly provided on the support rod 38. A first set of rods 301 is rotatably provided on the screening support frame 32, and a second set of rods 302 is sleeved on the first set of rods 301. The first set of rods 301 and the second set of rods 302 are respectively hingedly matched with the two sets of arc-shaped expansion plates 39. The first set of rods 301 and the second set of rods 302 are fixedly provided with expansion plates 303. The two sets of expansion plates 303 are arranged opposite to each other and are located in the sewage tank 11.

[0040] The two groups of unfolding plates 303 are respectively connected to the two sides of the screening support frame 32 with folding unfolding frames 304, and the ends of the two groups of folding unfolding frames 304 are connected to the sliding blocks 305 arranged opposite to each other, and a compression spring 306 is arranged between each group of sliding blocks 305 and the screening support frame 32, and a clamping wheel is arranged on the top of each group of sliding blocks 305.

[0041] When the sewage in the sewage treatment tank 1 is fully mixed with the disinfectant, the impurities therein will be at the bottom of the sewage tank 11 in the sewage treatment tank 1. At this time, the driving rod 22 no longer rotates, and the adjusting frame 24 moves downward. At this time, the resistance rod 28 on the adjusting frame 24 will contact the pressing part of the water valve 14, and then the water valve 14 will be opened to enable the sewage in the upper layer of the sewage tank 11 to be discharged outward through the water valve 14. At the same time, as the adjusting frame 24 moves downward, the adjusting frame 24 will drive the adjusting rack 29 to move downward, and the downward movement of the adjusting rack 29 will drive the adjusting gear 201 to rotate, thereby causing the moving rack 202 to move upward. After the moving rack 202 moves upward, it contacts the wedge-shaped frame 36 on the outer wall of the moving frame 34, thereby driving the wedge-shaped frame 36 to make the moving frame 34 move upward on the screening support frame 32 until the wedge-shaped frame 36 and the screening support frame 32 are aligned. When the wedge-shaped groove 37 of the screening support frame 32 is engaged, the folding and unfolding frame 304 is unfolded, and the folding and unfolding frame 304 is unfolded. A baffle is formed between the unfolded folding and unfolding frame 304 and the unfolding plate 303 and is in a closed state. When the water valve 14 discharges the precipitated sewage in the sewage treatment box 1, the sludge precipitated at the bottom can be effectively blocked by the unfolding plate 303 and the folding and unfolding frame 304, so as to prevent the discharged sewage from containing sludge.

[0042] When rainwater enters the sewage treatment tank 1, it will contain large impurities such as branches and leaves that have not been filtered out. Such impurities entering the sewage treatment tank 1 will affect the treatment of the sewage. The screening support frame 32 is in the sewage tank 11. The two sets of unfolding plates 303 and folding unfolding frames 304 arranged on the screening support frame 32 are initially in a folded state, so that the larger impurities contained in the sewage can fall between the unfolding plates 303 and the folding unfolding frames 304 to block them, thereby facilitating the subsequent screening of sludge and larger impurities in the sewage.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a plurality of shielding members 5 are provided on the inner wall of the screening support frame 32 respectively below the two groups of wedge-shaped pressure plates 41, and the plurality of shielding members 5 include a moving block 51 slidably provided on the inner wall of the screening support frame 32, and the moving blocks 51 on the plurality of folding members are connected to the bottom of the wedge-shaped pressure plates 41, and a rotating rod 52 is rotatably provided on the moving block 51, and a moving plate 53 is provided on the rotating rod 52, and a slot is provided on the moving plate 53, and a stopper that contacts the slot on the moving plate 53 is provided on the inner wall of the screening support frame 32, and a baffle 54 is fixedly provided on the rotating rod 52, and the baffle 54 is located above the folding and unfolding frame 304;

[0044] When the folding and unfolding frame 304 is unfolded on the screening support frame 32, the sliding block 305 connected to the upper end of the folding and unfolding frame 304 will move. At this time, the card wheel set on the sliding block 305 contacts the wedge-shaped pressure plate 41, and the wedge-shaped pressure plate 41 will move downward under the drive of the elastic spring 42. The downward movement of the wedge-shaped pressure plate 41 will drive the moving block 51 to move downward, and the moving block 51 will drive the rotating rod 52 to move downward. The card slot of the moving plate 53 on the rotating rod 52 will be limited and rotated under the contact of the block on the screening support frame 32. 53 will drive the rotating rod 52 to rotate, and the baffle plate 54 on the rotating rod 52 will rotate horizontally to cover the unfolding plate 303 and the folding unfolding frame 304 set at the bottom, and the impurities located on the unfolding plate 303 and the folding unfolding frame 304 will be located between the baffle plate 54, the unfolding plate 303 and the folding unfolding frame 304. Through this arrangement, the impurities located on the unfolding plate 303 and the folding unfolding frame 304 are blocked when the water valve 14 drains water outwards, thereby preventing the impurities from flowing out together with the sewage when the sewage flows out.

[0045] In this embodiment, Figure 1 and Figure 2 As shown, the sludge collecting tank 15 in the sewage treatment box 1 is arranged at an inclined position where it is connected to the sewage tank 11. An elastic wedge-shaped retaining frame 6 that contacts the wedge-shaped frame 36 is arranged on the inner wall of the sewage treatment box 1 above the sludge collecting tank 15. A filter plate 61 is arranged above the sludge collecting tank 15. An opening is arranged on the outer wall of the sewage treatment box 1 close to the sludge collecting tank 15.

[0046] After the sewage after sedimentation is discharged outwardly under the drive of the water valve 14, the screening support frame 32 is driven by the set driving electric cylinder 31 to move as a whole toward the sludge collecting tank 15. At this time, the scraper 33 on the screening support frame 32 will contact the sludge at the bottom of the sewage tank 11, and then scrape the sludge into the sludge collecting tank 15, so that the precipitated sludge can be in the sludge collecting tank 15, and the screening support frame 32 will move to the filter plate 61 above the sludge collecting tank 15. At this time, the wedge frame 36 clamped on the screening support frame 32 will contact the elastic wedge-shaped retaining frame 6, and then the elastic wedge The wedge-shaped frame 36 is driven by the wedge-shaped retaining frame 6 to separate from the wedge-shaped groove 37. After the wedge-shaped frame 36 is separated from the wedge-shaped groove 37, the movable frame 34 is reset under the drive of the pressure spring 35, so that the unfolding plate 303 and the folding unfolding frame 304 are in the folded state again. The impurities on the unfolding plate 303 and the folding unfolding frame 304 in the folded state will fall onto the filter plate 61, and then the larger impurities can be screened by the filter plate 61, and the operator can process the impurities remaining on the unfolding plate 303 and the folding unfolding frame 304 through the opening opened outside the sewage treatment tank 1.

[0047] The use method and advantages of the present invention: The use method of the multi-stage water resource treatment device has the following working process:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown: when rainwater is collected and treated as a water resource, the rainwater is discharged into the sewage treatment tank 1 through the water inlet 12 at the top of the sewage treatment tank 1, and then the disinfectant is discharged through the feed port 13 at the top of the sewage treatment tank 1 to filter the impurities in the rainwater. At this time, the driving motor 21 drives the driving rod 22 to rotate, and the driving rod 22 rotates to drive the sleeve column 23 to rotate. The two sets of stirring racks 25 are driven by the sleeve column 23 and the adjusting rack 24 to make the stirring racks 25 in an unfolded state, and then when the driving rod 22 rotates, it can drive the set stirring rack 25 to stir the sewage and disinfectant in the sewage treatment tank 1, and the adjusting rack 24 is driven by the set pushing electric cylinder 27 to move, and the movement of the adjusting rack 24 can drive the sleeve column 23 to move, and then the sleeve column 23 can slide on the driving rod 22, and the sliding of the sleeve column 23 can pull the hinged frame 26 to move, so that the hinged frame 26 drives the two sets of stirring racks 25 to open and close at a larger angle, thereby improving the effect of mixing sewage and gel, and improving the efficiency of its sewage treatment;

[0049] When rainwater enters the sewage treatment tank 1, it will contain large impurities such as branches and leaves that have not been filtered, and such impurities entering the sewage treatment tank 1 will affect the treatment of the sewage. The screening support frame 32 is in the sewage tank 11, and the two sets of unfolding plates 303 and folding unfolding frames 304 arranged on the screening support frame 32 are initially in a folded state, so that the larger impurities contained in the sewage can fall between the unfolding plates 303 and the folding unfolding frames 304 to block them, thereby facilitating the subsequent screening of the sludge and larger impurities in the sewage;

[0050] When the sewage in the sewage treatment tank 1 is fully mixed with the disinfectant, the impurities therein will be at the bottom of the sewage tank 11 in the sewage treatment tank 1. At this time, the driving rod 22 no longer rotates, and the adjusting frame 24 moves downward. At this time, the resistance rod 28 on the adjusting frame 24 will contact the pressing part of the water valve 14, and then the water valve 14 will be opened to enable the sewage in the upper layer of the sewage tank 11 to be discharged outward through the water valve 14. At the same time, as the adjusting frame 24 moves downward, the adjusting frame 24 will drive the adjusting rack 29 to move downward, and the downward movement of the adjusting rack 29 will drive the adjusting gear 201 to rotate, thereby causing the moving rack 202 to move upward. After the moving rack 202 moves upward, it contacts the wedge-shaped frame 36 on the outer wall of the moving frame 34, thereby driving the wedge-shaped frame 36 to make the moving frame 34 move upward on the screening support frame 32 until the wedge-shaped frame 36 and the screening support frame 32 are aligned. When the wedge-shaped groove 37 of the screening support frame 32 is engaged, the folding and unfolding frame 304 is unfolded, and the folding and unfolding frame 304 is unfolded. A baffle is formed between the unfolded folding and unfolding frame 304 and the unfolding plate 303 and is in a closed state. When the water valve 14 discharges the precipitated sewage in the sewage treatment box 1, the sludge precipitated at the bottom can be effectively blocked by the unfolding plate 303 and the folding and unfolding frame 304, so as to prevent the discharged sewage from containing sludge.

[0051] When the folding and unfolding frame 304 is unfolded on the screening support frame 32, the sliding block 305 connected to the upper end of the folding and unfolding frame 304 will move. At this time, the card wheel set on the sliding block 305 contacts the wedge-shaped pressure plate 41, and the wedge-shaped pressure plate 41 will move downward under the drive of the elastic spring 42. The downward movement of the wedge-shaped pressure plate 41 will drive the moving block 51 to move downward, and the moving block 51 will drive the rotating rod 52 to move downward. The card slot of the moving plate 53 on the rotating rod 52 will be limited and rotated under the contact of the block on the screening support frame 32. 53 will drive the rotating rod 52 to rotate, and the baffle plate 54 on the rotating rod 52 will rotate horizontally to cover the unfolding plate 303 and the folding unfolding frame 304 set at the bottom, and the impurities on the unfolding plate 303 and the folding unfolding frame 304 will be located between the baffle plate 54, the unfolding plate 303 and the folding unfolding frame 304. Through this arrangement, the impurities on the unfolding plate 303 and the folding unfolding frame 304 are blocked during the water discharge process of the water valve 14, so that the impurities are prevented from flowing out together with the sewage when the sewage flows out;

[0052] After the sewage after sedimentation is discharged outwardly under the drive of the water valve 14, the screening support frame 32 is driven by the set driving electric cylinder 31 to move as a whole toward the sludge collecting tank 15. At this time, the scraper 33 on the screening support frame 32 will contact the sludge at the bottom of the sewage tank 11, and then scrape the sludge into the sludge collecting tank 15, so that the precipitated sludge can be in the sludge collecting tank 15, and the screening support frame 32 will move to the filter plate 61 above the sludge collecting tank 15. At this time, the wedge frame 36 clamped on the screening support frame 32 will contact the elastic wedge-shaped retaining frame 6, and then the elastic wedge The wedge-shaped frame 36 is driven by the wedge-shaped retaining frame 6 to separate from the wedge-shaped groove 37. After the wedge-shaped frame 36 is separated from the wedge-shaped groove 37, the movable frame 34 is reset under the drive of the pressure spring 35, so that the unfolding plate 303 and the folding unfolding frame 304 are in the folded state again. The impurities on the unfolding plate 303 and the folding unfolding frame 304 in the folded state will fall onto the filter plate 61, and then the larger impurities can be screened by the filter plate 61, and the operator can process the impurities remaining on the unfolding plate 303 and the folding unfolding frame 304 through the opening opened outside the sewage treatment tank 1.
