Technical Field
[0001] The utility model relates to the technical field of silt flushing in sedimentation basins, in particular to a self-cleaning parallel type infiltration destruction silt flushing system. Background Art
[0002] my country's rivers have prominent characteristics. First, water resources are unevenly distributed, and second, the sediment content is high. In hydropower stations and other projects, it is crucial to deal with river sediment. Large particles of sediment are easy to settle at the tail of the reservoir, while small particles of harmful sediment may enter the waterway, causing deposition and wear of equipment. When the sand content and particle size of the water cannot meet the water use requirements, it is necessary to use a sedimentation tank to pre-precipitate the sediment, and then introduce clean water to generate electricity, so as to significantly improve the efficiency of the hydropower station.
[0003] However, the current sedimentation tank has certain limitations in flushing silt, with low flushing efficiency and a large consumption of water resources. The flushing effect is not ideal and requires manual cleaning or the use of a sludge scraper, which consumes a lot of cost. Therefore, a self-cleaning parallel infiltration destruction flushing system is proposed to address the above problems.
[0004] For example, CN219840197U discloses a pipeline silt flushing device in the soil protection and reduction stage, comprising: a hard silt flushing pipe, a remote sensing fixture, a water hose clip, a water hose and a control device; the hard silt flushing pipe is fixedly connected to one end of the water hose through the water hose clip, and the other end of the water hose is fixedly connected to the control device; a plurality of hard silt flushing pipes are arranged at the bottom of the pipeline in a straight array structure; the hard silt flushing pipes are fixed to the bottom of the pipeline through a remote sensing fixture, and the remote sensing fixture is wirelessly connected to the control device; by arranging a hard silt flushing pipe with a nozzle at the bottom of the pipeline, water is transported through the water hose to dredge the silt accumulated at the bottom of the pipeline; the device is arranged in a straight array structure, and the positions of the silt flushing pipes are not arranged at the same time along the water flow direction, the silt flushing is uneven, and the silt flushing area is small; the traditional hydraulic silt flushing method is adopted, the flushing efficiency is low, it is difficult to flush thoroughly, and more water resources are consumed at the same time; the silt flushing pipes do not take anti-clogging measures, which affects the life of the device, and the later processing consumes manpower and material resources. Summary of the invention

The straight holes are located on the downstream side of the sedimentation tank of the flushing and silting pipe and its lower half, and are evenly arranged in a straight line.
[0011] In a preferred solution, the diameters of the inclined holes and the straight holes gradually increase from the inlet end to the end of the flushing and silting pipe.
[0012] In a preferred solution, the system self-starting sensor adopts a density sensor, which is provided with an average density threshold and is installed at the end of each flushing and silting pipe, and all density sensors are placed at the same elevation.
[0013] In the preferred scheme, the system self-starting sensor is set to two starting modes, namely a first silt flushing mode and a second silt flushing mode. The first silt flushing mode is started when the average density measured by all sensors exceeds the average density threshold, and the press is started after all valves are opened; the second silt flushing mode is started when the density measured by a single sensor exceeds the point density threshold, and the press is started after all ventilation pipe valves and the silt flushing pipe valve at the inlet of the silt flushing pipe corresponding to the super-threshold sensor are opened.
[0014] In a preferred solution, the silt flushing pipe valve, the vent pipe valve and the press valve are all electric control valves, which are electric stop valves or electric ball valves.
[0015] The utility model provides a self-cleaning parallel penetration destruction silt flushing system, which has the following beneficial effects:
[0016] 1. The ventilation pipe of the utility model is connected to the silt flushing pipe, which is arranged in parallel and staggered to form a large rectangular silt flushing area, so that the high-pressure gas (water flow) ejected by the press can quickly penetrate and destroy the silt;
[0017] 2. The utility model can coordinate the control of the flushing pipe valve and the vent pipe valve to adjust the internal pressure of the vent pipe and the flushing pipe, change the flushing intensity, and achieve a self-cleaning effect;
[0018] 3. The utility model is provided with two groups of flushing and silting pipe openings, and different apertures are set according to the pressure change in the pipe, which not only ensures uniform outflow, but also effectively prevents the flushing and silting pipe from being blocked;
[0019] 4. The diameter of the inclined hole and the straight hole of the utility model gradually increases from the entrance to the end of the flushing and silting pipe to balance the different pressure distributions in the pipe, so that the outflow velocity is consistent and the outflow is uniform;
[0020] 5. The inclined holes on the upper part of the utility model silt flushing pipe are evenly distributed in a plum blossom shape, so that the outflow is uniform, ensuring that the high-pressure fluid is more likely to form upward pressure on the bottom of the pool after the outflow, so as to better utilize the penetration damage for silt flushing, and the opening is facing the downstream of the sedimentation tank, which effectively prevents silt from rushing into the pipe and plays a role in preventing siltation;
[0021] 6. The straight holes of the utility model flushing and silting pipe are arranged on the backwater side of the flushing and silting pipe and are evenly arranged in a straight line, so that the outflow is uniform, and at the same time, silt is prevented from entering and the sediment in the pipe is discharged, playing an anti-clogging role;
[0022] 7. The utility model adopts density sensor as self-starting sensor, and the control system opens and closes automatically, which reduces manpower and material resources, is low-consumption and low-carbon, and is equipped with multiple sensors connected to the end of each section of the flushing and silting pipe, which can identify the thickness of silt in different areas, so as to carry out targeted flushing and silting, saving water resources;
[0023] 8. The utility model sets the system self-starting sensors at equal distances and elevations to ensure that the average density value measured is accurate, so that the system can accurately determine the overall siltation degree in the sedimentation tank and start at the right time, thereby effectively reducing the carbon emissions of the device;
[0024] 9. The utility model has two start-up modes, which can carry out targeted flushing according to the coverage of silt deposits, and can effectively save water resources;
[0025] 10. The valves of the silt flushing pipe, the vent pipe valve and the press valve of the utility model are all electric control valves, which adopt electric stop valves or electric ball valves, so as to match the system self-starting sensor, control the automatic opening and closing of the silt flushing system, and effectively reduce manpower and material resources;
[0026] 11. The material of the silting pipe and the ventilation pipe in the utility model is PVC pipe or steel pipe. In a small-volume sedimentation tank, PVC pipe is selected, which has a long service life and low cost. In a large-volume sedimentation tank, the silting strength of the system is required to be higher. The steel pipe is selected to ensure that the high-pressure fluid does not damage the system pipeline and ensure the life of the system;

[0034] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments:
[0035] Example 1
[0036] like Figures 1 to 4 As shown, a self-cleaning parallel infiltration destruction and silt flushing system comprises a group of parallel ventilation pipes 3, the inlet of the ventilation pipe 3 is connected to a press 1, the outlet of the press 1 is provided with a press valve 7, the end of the ventilation pipe 3 is provided with a ventilation pipe valve 6, a plurality of silt flushing pipes 2 are relatively staggeredly arranged on the group of parallel ventilation pipes 3, the inlet end of the silt flushing pipe 2 is provided with a silt flushing pipe valve 4, the end of the silt flushing pipe 2 is closed, and a system self-starting sensor 5 is provided on the outside of the end.
[0037] In this embodiment, the press machine 1 adopts an air compressor or a water pump; the flushing and silting pipe 2 and the ventilation pipe 3 are made of PVC pipes or steel pipes; the plurality of flushing and silting pipes 2 are arranged in a staggered manner on a group of parallel ventilation pipes 3, and the distances between them are equal;
[0038] The flushing and silting pipe 2 is provided with a plurality of inclined holes 21 and straight holes 22. The inclined holes 21 are located at the upper part of the flushing and silting pipe 2, are evenly distributed in a plum blossom shape, and are opened toward the downstream of the sedimentation tank. They are arranged at an angle with the vertical plane. The straight holes 22 are located at one side of the downstream sedimentation tank of the flushing and silting pipe 2 and its lower half, and are evenly arranged in a straight line.
[0039] The diameters of the inclined holes 21 and the straight holes 22 gradually increase from the inlet end to the end of the flushing and silting pipe 2;
[0040] The system self-starting sensor 5 adopts a density sensor, which is provided with an average density threshold and is installed at the end of each flushing and silting pipe 2. All density sensors are placed at the same elevation;
[0041] The system self-starting sensor 5 is set to two starting modes, namely the first silt flushing mode and the second silt flushing mode. The first silt flushing mode is started when the average density measured by all sensors exceeds the average density threshold, and the press 1 is started after all valves are opened; the second silt flushing mode is started when the density measured by a single sensor exceeds the point density threshold, and the press 1 is started after all the vent pipe valves 6 and the silt flushing pipe valve 4 at the inlet of the silt flushing pipe 2 corresponding to the over-threshold sensor are opened;
[0042] The silt flushing pipe valve 4, the vent pipe valve 6 and the press valve 7 are all electric control valves, which are electric stop valves or electric ball valves.
[0043] In specific use, when the silt at the bottom of the entire sedimentation tank reaches a certain amount, the water density in the tank changes accordingly. When the average density measured by all sensors exceeds the average density threshold, the system automatically starts the first flushing and silting mode, that is, after opening all valves, the two presses 1 are started at the same time. Subsequently, the press 1 immediately passes high-pressure fluid into the vent pipe 3, and the fluid enters the rectangular flushing and silting area through each flushing and silting pipe 2. During the flushing and silting process, the fluid is ejected through the inclined hole 21 and the straight hole 22 on the flushing and silting pipe 2 respectively. Since the end of the flushing and silting pipe 2 is closed, the pressure in the pipe at the end is increased, and the aperture that increases along the flow direction can balance the pressure to flush and silt evenly. The high-pressure fluid flowing out of the inclined hole 21 forms an upward pressure at the bottom of the sedimentation tank to loosen the silt, and the longitudinal fluid flowing out of the straight hole 22 can take away the silt to achieve the purpose of flushing and silting. In addition, after the flushing and silting is completed, the system closes the valves 6 of the two vent pipes, and the press 1 automatically closes after passing the high-pressure fluid into the vent pipe 3 for a period of time to perform self-cleaning to prevent pipeline clogging.
[0044] Example 2
[0045] In another preferred embodiment, on the basis of the above-mentioned embodiment 1, during specific use, when the silt in a small area at the bottom of the sedimentation tank reaches a certain amount, the water density in the area changes accordingly. When the density measured by a single sensor in the area exceeds the point density threshold, the system automatically starts the second flushing mode, that is, after opening all the vent pipe valves 6 and the flushing pipe valve 4 at the inlet of the flushing pipe 2 corresponding to the super-threshold sensor, two presses 1 are started at the same time. Subsequently, the press 1 immediately passes high-pressure fluid into the vent pipe 3, and the fluid enters the flushing area through the flushing pipe 2 corresponding to the sensor for flushing. At this time, only a few valves are open, and the pressure in the pipe is relatively large. The flushing effect is ideal and water-saving. In addition, after the flushing is completed, the system closes the two vent pipe valves 6, and the press 1 automatically closes after passing high-pressure fluid into the vent pipe 3 for a period of time to perform self-cleaning to prevent pipeline blockage.
[0046] In a preferred embodiment, the press machine 1 adopts an air compressor or a water pump; the above configuration provides high-pressure fluid for the silt flushing system, so that after it flows out of the silt flushing pipe 2, it creates a greater upward pressure on the bottom of the sedimentation tank, loosens the silt, and enhances the silt flushing effect.
[0047] In the preferred solution, the flushing and silting pipe 2 and the ventilation pipe 3 are made of PVC pipe or steel pipe. Different materials are selected according to the volume of the sedimentation tank. PVC pipe is selected for a small sedimentation tank, which has a long service life and low cost. A large sedimentation tank has higher requirements for flushing and silting strength. Steel pipe is selected to ensure that the high-pressure fluid does not damage the system pipeline.
[0048] In the preferred solution, the plurality of silt flushing pipes 2 are relatively staggeredly arranged on a group of parallel ventilation pipes 3, and the distances between them are equal; the above arrangement can form a large-area rectangular silt flushing area with uniform outflow, thereby achieving efficient silt removal in a shorter time.
[0049] In the preferred scheme, the silt flushing pipe 2 is provided with a plurality of inclined holes 21 and straight holes 22. The inclined holes 21 are located at the upper part of the silt flushing pipe 2, are evenly distributed in a plum blossom shape, and are opened toward the downstream of the silt settling tank. They are set at an angle with the vertical plane. The straight holes 22 are located on the downstream side of the silt flushing pipe 2 and its lower half, and are evenly arranged in a straight line. The inclined holes 21 are inclined toward the downstream, which ensures that it is easier to form an upward pressure on the bottom of the tank after the high-pressure fluid flows out, and also effectively prevents the silt in the water body from entering the silt flushing pipe 2 through the inclined holes 21 to cause blockage. The straight holes 22 are set on the downstream side of the silt flushing pipe 2 and its lower half, so as to ensure that the high-pressure fluid flowing out can quickly carry away the loose silt. In addition, the plum blossom-shaped and linear distribution of the holes can ensure uniform outflow and enhance the silt flushing effect.
[0050] In the preferred embodiment, the apertures of the inclined holes 21 and the straight holes 22 gradually increase from the inlet end to the end of the silt flushing pipe 2. Since the end of the silt flushing pipe 2 is closed, the pressure in the pipe at the end increases, and the aperture that increases along the flow direction can balance the pressure to evenly flush the silt, thereby enhancing the silt flushing effect.
[0051] In the preferred solution, the system self-starting sensor 5 adopts a density sensor, which is provided with an average density threshold value and is installed at the end of each flushing and silting pipe 2. All density sensors are placed at the same elevation. Since the flushing and silting pipes 2 are arranged at equal distances, the system self-starting sensors 5 installed at their ends can also be evenly arranged, and they are placed at the same elevation, so that the average value measured can more accurately reflect the accumulation amount of the overall silt.
[0052] In the preferred scheme, the system self-starting sensor 5 is set to two starting modes, namely the first flushing and silting mode and the second flushing and silting mode. The first flushing and silting mode is started when the average density measured by all sensors exceeds the average density threshold, and the press 1 is started after all valves are opened; the second flushing and silting mode is started when the density measured by a single sensor exceeds the point density threshold, and the press 1 is started after all the ventilation pipe valves 6 and the flushing and silting pipe valve 4 at the inlet of the flushing and silting pipe 2 corresponding to the super-threshold sensor are opened; the above settings can carry out targeted flushing and silting according to the coverage range of the silt, while enhancing the flushing and silting intensity, effectively saving water resources.
[0053] In the preferred solution, the silt flushing pipe valve 4, the vent pipe valve 6 and the press valve 7 are all electric control valves, using electric stop valves or electric ball valves; the above settings are matched with the system self-starting sensor 5, and an electric control valve is used to control the silt flushing system to open and close automatically, effectively reducing manpower and material resources.
[0054] In summary, the utility model provides a self-cleaning parallel infiltration destruction silt flushing system. By setting a press machine 1, a high-pressure fluid is provided for the silt flushing system, so that after the silt flushing pipe 2 flows out, a greater upward pressure is created on the bottom of the sedimentation tank, so that the silt is loosened and the silt flushing effect is enhanced; by setting the silt flushing pipe 2 and the ventilation pipe 3 made of PVC pipe or steel pipe material, the silt flushing effect and system life are guaranteed; by setting a plurality of silt flushing pipes 2 on a group of parallel ventilation pipes 3, a relatively staggered and equidistant arrangement is formed to form a large-area rectangular silt flushing area with uniform outflow, so as to achieve efficient silt removal in a shorter time; by setting the inclined holes 21 and the straight holes 22 arranged in plum blossom shape and straight line shape, uniform silt flushing is guaranteed; by setting the directions of the inclined holes 21 and the straight holes 22, the principle of infiltration destruction is fully utilized for silt flushing, and the problems of the traditional device capacity are overcome. The problem of easy clogging; by setting the aperture of the inclined hole 21 and the straight hole 22 to gradually increase from the inlet end to the end of the silt flushing pipe 2, the pressure in the pipe is balanced to enhance the silt flushing effect; by setting the system self-starting sensor 5 evenly at the same elevation, the system can accurately judge the degree of siltation and start at the right time, thereby effectively reducing the carbon emissions of the device; by setting an electric control valve instead of a traditional valve, the system can be automatically controlled to reduce manpower and material resources; in addition, the system self-starting sensor 5 is set to two start-up modes, which can be used for targeted silt flushing according to the coverage of the silt, while enhancing the silt flushing intensity, it can also effectively save water resources. The overall structure of the silt flushing system is simple, the cost is low, the operation is easy, the service life is long, and it is suitable for the flushing of different types of siltation tanks. Small ideas solve big problems and have high practical application value.
