In order to enhance the adsorption force, the second adsorption part 107 and the first adsorption part 105 may respectively adopt magnets which are adapted to each other, so that not only the second adsorption part 107 and the first adsorption part 105 may be adsorbed together by magnetic force, but also, because the magnetic field of the magnets has a certain range, even if the second adsorption part 107 is separated from the first adsorption part 105, magnetic force exists between the second adsorption part 107 and the first adsorption part 105, which is not only beneficial for the second adsorption part 107 to automatically reset, but also has a larger adsorption force, and can more firmly seal the water outlet 102.

As another example, the first adsorption part 105 may be configured at the water outlet 102, and in this case, the second adsorption part 107 may be disposed at the blocking part 200, for example, in a preferred embodiment, the first adsorption part 105 may be configured at the water outlet 102 and form a circle along the circumferential direction of the water outlet 102, and meanwhile, the second adsorption part 107 may be disposed at the blocking part 200 and form a circle so as to be matched with the first adsorption part 105.

To facilitate the deposition of mud at the bottom of the well, in further embodiments, at least the lower portion of the well body 100 may be configured as a conical structure. For example, in practice, the entire well 100 sidewall may be constructed with a taper; as another example, as shown in fig. 1-6, the upper portion of the well body 100 may be configured as a cylindrical structure and the lower portion of the well body 100 as a conical structure, i.e., the cross-sectional area of the well body 100 gradually decreases in a direction from the wellhead 101 to the bottom of the well, at least at a location near the bottom of the well, so as to guide the deposition of contaminants within the well and converge in a direction toward the bottom drain 102.

The blocking member 200 has various embodiments, for example, the blocking member 200 may be a flat cover so as to cover the entire drain opening 102. In the preferred embodiment provided by this embodiment, as shown in fig. 3 and 5, the inner side of the second annular sealing surface 201 is configured as an upwardly convex structure 202, and the height of the convex structure 202 gradually increases along the direction inward of the radius of the second annular sealing surface 201, in practice, the upper surface of the convex structure 202 may be an arc surface or an inclined surface, for example, as shown in fig. 1 to 5, the upper surface of the convex structure 202 is configured as an arc surface, in which case, the blocking component 200 may preferably be an arc plate, which is convenient for molding and light in weight; and the connecting frame 108 is connected to the convex structure 202, as shown in fig. 3 or fig. 5, when the plugging member 200 closes the drainage opening 102, the convex structure 202 is just located in the well body 100, as shown in fig. 3 and fig. 5, because the upper surface of the convex structure 202 is an arc surface or an inclined surface, through the cooperation with the side wall of the well body 100, on one hand, the accumulated silt in the well body 100 can be guided to be accumulated at the position corresponding to the second annular sealing surface 201, which is more beneficial to rapid drainage and flushing, and on the other hand, because no plane or concave surface exists, the accumulated silt can not be attached to the upper surface of the plugging member 200 in the drainage process, which is beneficial to completely draining all the accumulated silt in the well.

In actual use, the abandon well can be connected with the existing upper well body 500 (as shown in fig. 14) so as to be the bottom of the whole well, so that the water body can flow into the well body 100 through the well mouth 101, and of course, the side wall of the well body 100 can also be provided with a side water inlet so that the incoming water can flow into the well body 100 through the side water inlet; the waste trap is mainly used for receiving and storing incoming water, and can discharge the incoming water and washed pollutants (accumulated sludge) through the water outlet 102 at the bottom. The specific working process is as follows:

1. when the upstream water enters the well, the pollutants in the water body begin to settle and gradually form sludge in the well due to the small initial water amount and low flow velocity, as shown in fig. 3. The newly formed and past accumulated silt in the well is gathered along the wall of the conical structure to the position of the bottom water outlet 102 under the action of gravity and water flow, and is accumulated above the blocking part 200. At the moment, because the liquid level in the well is lower, the buoyancy component 111 is at a low position under the action of gravity, the plugging component 200 keeps a closed position under the attraction effect of the magnet, and water is not drained from the bottom of the well and accumulated silt in the well is not washed away.

2. Along with the increase of the water, the liquid level in the well body 100 continuously rises, the pressure borne by the plugging component 200 is increased, meanwhile, the part of the buoyancy component 111 immersed into the water is also continuously increased, the buoyancy is increased, when the buoyancy is increased to a set threshold value, the buoyancy overcomes the pressure of the water above the plugging component 200, the accumulated silt gravity and the magnetic body adsorption force, the plugging component 200 is driven to move upwards, and the plugging component 200 is instantly opened, as shown in fig. 5; at this time, the water above the plugging component 200 is discharged downwards to form a flushing water flow, and the flushing water flow wraps the accumulated silt in the well and is discharged out of the well body 100, so that the flushing of the accumulated silt in the well is realized. In the process, as the plugging component 200 moves upwards, the two magnets are separated from each other magnetic field area, so that the opening of the plugging component 200 cannot be reduced after the plugging component is opened upwards, and a better flushing effect is achieved.

3. After the flushing is finished, the liquid level in the well is lowered, the buoyancy component 111 does not provide buoyancy any more, and the plugging component 200 moves downwards under the action of the gravity of the plugging component and the gravity of the buoyancy component 111; when the plugging member 200 approaches the bottom outlet 102, the first adsorption member 105 and the second adsorption member 107 attract each other, and the outlet 102 is closed, as shown in fig. 3, the plugging member 200 can form a sealing function on the bottom outlet 102 to wait for the next flushing.

In addition, in the present abandoning well, the lower part of the well body may be configured with a flange 114 to connect a drain pipe 400 by the flange 114, so that the drain pipe 400 can communicate with the drain opening, as shown in fig. 15, to drain from the bottom.

Example 2

In order to solve the problem of utilizing buoyancy to drive the blocking member 200 to be quickly separated from the water outlet 102 to realize instant water drainage, the main difference between the present embodiment 2 and the above embodiment 1 is that in the drainage well provided by the present embodiment, the buoyancy control mechanism further comprises a lever 112 and a fixedly installed support 104, the lever 112 is rotatably connected to the support 104 and forms a lever 112 mechanism, as shown in fig. 7-11; one end of the lever 112 is hinged (an existing hinge structure may be adopted, for example, the hinge may be realized by matching the hinge shaft 301 with the hinge hole 302, wherein the hinge hole 302 may be configured on the lever 112 and the connecting frame 108) to the connecting frame 108, and the other end is connected to the buoyancy member 111; at this time, the plugging member 200 is disposed outside the well 100 and below the water outlet 102, as shown in fig. 7-11, by providing the lever 112 mechanism and connecting the connecting frame 108 and the buoyancy member 111 to two ends of the lever 112 respectively, the principle of the lever 112 is utilized, so that in practical use, when the buoyancy member 111 rises under the effect of buoyancy, the plugging member 200 can be opened from below the water outlet 102, the opening and closing processes of the plugging member 200 are not affected by the accumulated silt in the well 100, the opening action of the plugging member 200 is facilitated to be faster and smoother, and the instant opening is facilitated.

In order to allow the connecting frame 108 to move strictly in the vertical direction, in a further embodiment, the lever 112 is configured with a kidney-shaped hole 113, the kidney-shaped hole 113 is arranged along the length direction of the lever 112, as shown in fig. 8 and 9, at the same time, the support 104 is provided with a pin 300 fitting the kidney-shaped hole 113, the pin 300 passes through the kidney-shaped hole 113, and both ends of the pin 300 are respectively constrained to the support 104, so that the lever 112 can rotate relative to the support 104, but also can move relative to the support 104, as shown in fig. 9 and 11, so that during the floating of the buoyant member 111, the lever 112 simultaneously rotates relative to the support 104 and moves relative to the support 104, thereby driving the connecting frame 108 to vertically rise/fall.

More specifically, as shown in fig. 9 and 11, the blocking member 200 is disposed below the drain opening 102, the lower end of the connecting frame 108 is connected to the blocking member 200, and the upper end of the connecting frame 108 extends into the well 100 through the drain opening 102 and is connected to the lever 112 after passing through the guide portion, so that the lever 112, the holder 104, and the buoyant member 111 can be disposed above the support 103, as shown in fig. 7. In order to achieve a better sealing effect, in a further embodiment, the first annular sealing surface 110 may be configured outside the water outlet 102, as shown in fig. 11, and the second annular sealing surface 201 should be configured on the upper surface of the blocking component 200 so as to be adapted to the first annular sealing surface 110, so that when the second adsorption component 107 adsorbs to the first adsorption component 105, the second annular sealing surface 201 fits to the first annular sealing surface 110 to achieve the sealing of the water outlet 102.

More perfectly, in this embodiment, the first adsorption part 105 and the second adsorption part 107 have various positional relationships, for example, the first adsorption part 105 may be disposed at the lower end of the guide cylinder 106, the second adsorption part 107 may be disposed at the connecting frame 108 and below the first adsorption part 105, as shown in fig. 12, when the annular sealing surface two 201 is attached to the annular sealing surface one 110, the second adsorption part 107 is just contacted and adsorbed to the first adsorption part 105. As another example, the first adsorption part 105 may be configured at the water outlet 102, and in this case, the second adsorption part 107 may be disposed at the blocking part 200, for example, in a preferred embodiment, the first adsorption part 105 may be configured at the water outlet 102 and form a circle along the circumferential direction of the water outlet 102, and meanwhile, the second adsorption part 107 may be disposed at the blocking part 200 and form a circle so as to be matched with the first adsorption part 105. In the first embodiment, the first adsorption part 105 may be configured on the back surface of the first annular sealing surface 110, or may be embedded in the first annular sealing surface 110; of course, the first suction member 105 may also be configured at the drain opening 102 such that the lower surface of the first suction member 105 may form the annular sealing surface one 110, as shown in fig. 7-11, i.e., the annular sealing surface one 110 may be the lower surface of the first suction member 105. Meanwhile, the second suction member 107 may be configured on the back surface (lower surface) of the second annular sealing surface 201 of the blocking member 200, or may be embedded in the second annular sealing surface 201, as shown in fig. 9 and 10; of course, the second suction member 107 may also be configured at the blocking member 200 such that the upper surface of the second suction member 107 may form the annular sealing surface two 201, i.e., the annular sealing surface two 201 may be the upper surface of the second suction member 107.

Similarly, in the present embodiment, the threshold value may be the sum of the self weight of the buoyancy member 111, the self weight of the blocking member 200, the self weight of the connecting frame 108, and the suction force between the first suction member 105 and the second suction member 107, and the threshold value may be controlled (set) by controlling the weight of the buoyancy member 111, the weight of the blocking member 200, the weight of the connecting frame 108, and the maximum suction force between the first suction member 105 and the second suction member 107 at the time of designing.

In actual use:

1. when the upstream water enters the well, pollutants in the water body begin to settle in the well to gradually form accumulated silt due to the small initial water amount and low flow velocity. Newly formed and past accumulated silt in the well is gathered to the position of the bottom hole outlet 102 along the wall of the conical structure under the action of gravity and water flow, and is attached to the upper part of the plugging component 200, as shown in fig. 9. At this time, the buoyancy member 111 is at a low position under the gravity due to the low liquid level in the well; the plugging member 200 plugs the drain opening 102 at the bottom of the well.

2. Along with the increase of water, the liquid level at the bottom of the well continuously rises, the pressure borne by the top of the plugging component 200 is increased, meanwhile, the part of the buoyancy component 111 immersed into the water body is also continuously increased, and the buoyancy is increased; when the buoyancy is increased to a certain degree, the buoyancy of the buoyancy component 111 is converted into downward thrust through the lever 112, and is transmitted to the plugging component 200 along the lever 112; in combination with the gravity of the water above the plugging member 200, the magnetic force between the first adsorption member 105 and the second adsorption member 107 is broken through, and the plugging member 200 is opened instantaneously, as shown in fig. 11. At this time, the water above the plugging component 200 is discharged downwards to form a flushing water flow, and the flushing water flow wraps the accumulated silt in the well and is discharged out of the well body 100, so that the flushing of the accumulated silt in the well is realized.

3. After the flushing is finished, the plugging component 200 is not subjected to the accumulated silt and the gravity of the water body any more, and at the moment, after the water body in the well is emptied, the buoyancy component 111 moves downwards under the self gravity to drive the plugging component 200 to move upwards; when the plugging member 200 approaches the water outlet 102 at the bottom of the well, the first adsorption member 105 and the second adsorption member 107 are adsorbed together, as shown in fig. 11, so that the plugging member 200 can form a sealing effect on the water outlet 102 at the bottom of the well and wait for the next flushing.

Example 3

The main difference between this embodiment 3 and the above embodiment 1 or 2 is that in the abandoning well provided in this embodiment, the sidewall of the well body 100 is further configured with a plurality of side water outlets 109, as shown in fig. 13, the side water outlets 109 are used for connecting pipelines downstream of municipal pipe networks, and can be used for draining water in daily small water amount. So that the abandoning well can shunt the upstream incoming water, shunt the dry-season domestic sewage and the rainy-season cleaner water body to different drainage pipe networks, reduce the total amount of pollutants discharged to the natural water body, particularly,

1. when upstream incoming water enters the well, as the initial water amount is small and the flow speed is not high, most of the situations are that rainfall does not occur, most of the incoming water of the well body 100 is domestic sewage, and when the part of the sewage continuously enters the well and reaches the position of the side water outlet 109, the part of the sewage overflows and enters a downstream pipeline to be discharged to a sewage plant; meanwhile, pollutants in the water body begin to settle in the well to gradually form accumulated silt. The newly formed and past accumulated silt in the well is gathered along the wall of the conical structure to the position of the bottom water outlet 102 under the action of gravity and water flow, and is accumulated above the blocking part 200. At this time, the plugging component 200 keeps a closed position under the attraction effect of the magnet, and water is not drained from the well bottom and accumulated silt in the well is not washed away.

2. Along with the increase of water or rainfall, the liquid level at the bottom of the well rises continuously, and after the liquid level exceeds the height of the lateral water outlet 109, the liquid level at the bottom of the well rises continuously, the pressure borne by the plugging component 200 is increased, meanwhile, the part of the buoyancy component 111 immersed into the water body is also increased continuously, and the buoyancy is increased; when the buoyancy is increased to a certain degree, the buoyancy of the buoyancy component 111 is converted into downward thrust through the lever 112, and the downward thrust is transmitted to the plugging component 200 along the connecting frame 108; the gravity of water above the plugging part 200 is combined to break through the suction force of the magnets around the plugging part 200 together, and the plugging part 200 is opened instantly; at this time, the water above the plugging component 200 is discharged downwards to form a flushing water flow, and the flushing water flow wraps the accumulated silt in the well and is discharged out of the well body 100, so that the flushing of the accumulated silt in the well is realized.

3. After the flushing is finished, the plugging component 200 is not subjected to the accumulated silt and the gravity of the water body any more, and at the moment, after the water body in the well is emptied, the buoyancy component 111 moves downwards under the self gravity to drive the plugging component 200 to move upwards; when the bottom of the plugging member 200 approaches the shaft, the magnet acts as an adsorption and the water outlet 102 is closed. The plugging member 200 seals the bottom discharge opening, discharges a small daily amount of water (through the side water outlet 109), and waits for the next flushing.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
