[0002] At present, there are usually no sewage pipes and sewage treatment systems in rural areas. Most residents will directly discharge domestic sewage into nearby ditches, causing pollution. They cannot treat domestic sewage for reuse, which also causes a waste of water resources. The single-phase flow negative pressure drainage system is an efficient rural domestic sewage treatment technology. It mainly uses negative pressure suction to create a pressure difference inside and outside the pipeline, pushing the sewage from the front collection well to the terminal sewage station. The siphon principle is used in the process to overcome the friction between the sewage and the pipeline, and achieve full pipe transmission of sewage.

[0003] The existing single-phase negative pressure drainage system used for rural domestic sewage treatment is usually controlled by multiple electromagnetic valves.

[0034] Furthermore, the driving assembly includes a telescopic member 19, an inclined slide seat 21, an inclined block 22, a slide frame 24, a rotating plate 1 25, and a rotating plate 27. The telescopic member 19 is installed on the inner wall of the reuse box 3, and the output end of the telescopic member 19 is connected to the slide frame 1 20, the inclined slide seat 21 is connected to the slide frame 1 20, the inclined block 22 is connected to the sealing cover 2 13, the inclined slide seat 21 and the inclined block 22 are slidably connected in a fitting manner, the slide frame 24 is connected to the sealing cover 4 23, and the slide frame 24 extends through the pipe 4 into the collection box 2, the two ends of the rotating plate 1 25 are respectively rotatably connected to one end of the slide frame 24 in the collection box 2 and the sealing cover 3 16, and the two ends of the rotating plate 27 are respectively rotatably connected to the sealing cover 11 and the slide frame 1 20.

[0035] like Figure 4 and 5As shown, by controlling the extension of the telescopic member 19, the sliding frame 1 20, the sealing cover 4 23, and the sliding frame 24 can be driven to slide, so that when the sealing cover 4 23 is pushed close to the pipe 4 and blocks it, the sliding frame 1 20 and the sliding frame 24 both slide to the right, which can drive the rotating plate 27 to rotate, push the sealing cover 11 to move up to open the air inlet pipe 9, and drive the rotating plate 1 25 to rotate, push the sealing cover 3 16 to move down to open the pumping pipe 2 6, and at the same time, the inclined slide seat 21 and the inclined block 22 slide in contact, push the sealing cover 2 13 to move up to block the pumping pipe 1 5, and facilitate the negative pressure pump 8 to only pump negative pressure into the collecting box 2, so as to collect the single-phase flow of domestic sewage filtered in the filter box 1 in the collecting box 2 for sedimentation;

[0036] By controlling the shortening of the telescopic member 19, the sealing cover 2 13 and the sealing cover 4 23 can be driven to open, while the sealing cover 1 11 and the sealing cover 3 16 are blocked, so that the negative pressure pump 8 only draws negative pressure into the reuse box 3, so as to collect the single-phase flow of domestic sewage that has been precipitated in the collection box 2 in the reuse box 3, and discharge it through the outlet pipe 37 for reuse.

[0037] Furthermore, a connection seat 26 is connected to the bottom of the sealing cover 11, and the connection seat 26 extends through the air inlet port 9 into the reuse box 3 and is rotatably connected to the rotating plate 27. Figure 5 As shown, it is convenient to connect the rotating plate 27 with the sealing cover 11.

[0038] Further, the inner walls on both sides of the reuse box 3 are connected to the slideway 17, and the slide frame 20 is slidably connected in the slideway 17. The inner walls on both sides of the collection box 2 are connected to the slideway 2 18, and the slide frame 24 is slidably connected in the slideway 2 18. Figure 2 and 3 As shown, the slideway 17 can stabilize the sliding of the slide frame 1 20 , and the slideway 2 18 can stabilize the sliding of the slide frame 24 .

[0039] Furthermore, the inner wall of the collection box 2 is connected with a guide slide bar 4 30, a slide bracket 31 is slidably sleeved on the guide slide bar 4 30, a scraper 33 for cleaning the bottom of the collection box 2 is connected to the lower end of the slide bracket 31, and a spring 2 32 is sleeved on the outer side of the guide slide bar 4 30, and the two ends of the spring 2 32 are respectively connected to the slide bracket 31 and the guide slide bar 4 30;

[0040] A slide plate 28 is connected to the slide frame 24, a fixed plate 29 is connected to the inner wall of the collection box 2, a limit slide box 34 is connected to the slide frame 31, a one-way limit block 35 is slidably connected in the limit slide box 34, and one end of the one-way limit block 35 extends to the outside of the limit slide box 34 and is set as an inclined surface, a spring three 36 is connected between the one-way limit block 35 and the inner wall of the limit slide box 34, the slide plate 28 slides between the fixed plates 29 on both sides, and the slide plate 28 and the fixed plate 29 both slide in contact with the one-way limit block 35.

[0041] like Figure 6 and 7 As shown, when the telescopic member 19 is extended, it will drive the slide frame 24 to slide, and push the slide plate 28 to slide to the right side of the collection box 2, squeeze the one-way limit block 35, and compress the spring three 36, so that the one-way limit block 35 slides into the inside of the limit slide box 34 until the slide plate 28 passes, and the one-way limit block 35 will pop out from the inside of the limit slide box 34 under the action of the spring three 36. At this time, when the telescopic member 19 is shortened and drives the slide frame 24 to slide to the left side of the collection box 2, the slide plate 28 and the one-way limit block 35 are contacted and limited, and the one-way limit block 35, the limit slide box 34 and the slide 31 are driven to slide to the left as a whole, so that each scraper 33 can clean the sediment at the bottom of the collection box 2. When the one-way limit block 35 moves to the left and contacts with the fixed plate 29, it will be gradually squeezed into the limit slide box 34 again. At this time, under the action of the spring two 32, the slide 31 will be pushed to slide to the right as a whole, and pass under the slide plate 28 to the reset state.

[0042] If necessary, water treatment equipment may be further provided in the collection box 2, so that the collection box 2 can not only precipitate the domestic sewage, but also perform relevant chemical treatment on the domestic sewage.

[0043] Working principle: In specific use, by controlling the extension and retraction of the telescopic member 19, when it is extended, the sliding frame 1 20 and the sliding frame 2 24 are pushed to slide to the right, and the sealing cover 4 23 is driven to block the pipeline 4 in the reuse box 3, and at the same time, the rotating plate 1 25 is driven to rotate and push the sealing cover 3 16 to move down to open the extraction pipe 2 6, and the inclined slide seat 21 and the inclined block 22 are driven to slide in a close relationship and push the sealing cover 2 13 to move up to block the extraction pipe 1 5, and the rotating plate 2 27 is driven to rotate and push the sealing cover 11 to move up to open the air inlet 9, so that the collection box 2 can be pumped with negative pressure by the negative pressure pump 8, and the filter in the filter box 1 can be filtered. The domestic sewage after the precipitate is collected into the collection box 2 through the single-phase flow of the pipe 4, and then the negative pressure pump 8 is turned off to allow the domestic sewage to settle in the collection box 2. Finally, the telescopic member 19 is controlled to shorten so that the sealing cover 4 23 and the sealing cover 2 13 are opened, and the sealing cover 1 11 and the sealing cover 3 16 are closed. In this way, after the negative pressure pump 8 is started again, the negative pressure in the reuse box 3 can be pumped, and the single-phase flow of the domestic sewage after the precipitate in the collection box 2 is collected into the reuse box 3, so that when the sealing cover 1 11 is opened next time and the reuse box 3 is in a normal pressure state, the domestic sewage in the reuse box 3 can be reused through the outlet pipe 37 to flush the toilet, etc.;

[0044] And when the slide frame 24 slides to the right, it squeezes the one-way limit block 35 and cannot push the slide 31 to move. When the slide frame 24 slides to the left, the slide plate 28 will contact and limit the one-way limit block 35, driving the slide 31 and the scraper 33 thereon to slide at the bottom of the collection box 2 until the one-way limit block 35 contacts and returns to its original position. During the process, the scraper 33 can clean the bottom of the collection box 2 to avoid long-term adhesion of sediment and reduce the sedimentation treatment effect.
