Wherein the elevation of the bottom of the second treatment area 40 at the location where it communicates with the first treatment area 20 is lower than the elevation of the bottom of the first treatment area 20 at the location where it communicates with the sewerage pipe 30; the point where the second treatment region 40 communicates with the first treatment region 20 may refer to a point where sewage is delivered from the second treatment region 40 to the first treatment region 20 or from the first treatment region 20 to the second treatment region 40. The second treatment area 40 may be in communication with an external source of gas, which is a device for charging the second treatment area 40 with compressed gas, so as to form a gas pressure in the second treatment area 40, and further to press the wastewater in the second treatment area 40 to flow into the first treatment area 20, i.e. the gas pressure formed by the gas pressure charged by the source of gas is understood as the driving force in this specification.

Therefore, the sewage output from the first treatment area 20 can be regulated and stored by the sewage treatment device provided in the embodiment of the present specification when there is rainfall, and the sewage regulation and storage can be stopped when there is no rainfall, that is, the sewage output from the first treatment area 20 is directly input to the sewage discharge pipe 30;

that is, when the sewage needs to be regulated and stored in the rainfall, only the sewage output from the first treatment region 20 flows into the second treatment region 40 by gravity for storage, so that only rainwater exists in the sewage discharge pipeline 30, and when the sewage needs to be output in the sunny day, only the sewage stored in the second treatment region 40 flows into the sewage discharge pipeline 30 through the first treatment region, thereby effectively avoiding the technical defects that the sewage input from the first treatment region 20 directly enters the sewage discharge pipeline for output in the prior art, the natural water body is extremely easy to cause serious pollution in the rainy day, or the sewage treatment facility has overlarge treatment pressure, the resource waste and the like, achieving the technical effect of regulating and storing the sewage when the sewage does not need to be discharged, and having the characteristics of simple structure, convenient operation and wide applicability.

As another application environment of the embodiment of the present specification, for the above-mentioned "sewage requiring regulation", a regulation node may be set according to the size of rainfall for regulation, for example, when the rainfall is relatively large, if the sewage output from the first treatment area directly enters the sewage drainage pipe and then is mixed with rainwater, the mixed water of the rainwater and the sewage is easily polluted when being directly discharged into the natural water body, and if being directly discharged into the sewage treatment facility for treatment, a large amount of relatively clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, the sewage discharged from the first treatment area 20 can be regulated by the sewage treatment apparatus provided in the embodiment of the present disclosure when the rainfall is relatively large, and the sewage regulation can be stopped when the rainfall is relatively small, that is, the sewage discharged from the first treatment area 20 is directly supplied to the sewage pipe 30.

That is, when sewage needs to be regulated, only the sewage output by the first treatment area 20 flows into the second treatment area 40 through gravity for storage, so that only rainwater exists in the sewage discharge pipeline 30, and when sewage needs to be output, only the sewage stored in the second treatment area 40 flows into the sewage discharge pipeline 30 through the first treatment area 20, thereby effectively avoiding the technical defects that the sewage input by the first treatment area 20 directly enters the sewage discharge pipeline for output in the prior art, the natural water body is extremely easy to cause serious pollution in rainy days, or the treatment pressure of the sewage treatment facility is too large, the resource waste and the like, achieving the technical effect of regulating and storing the sewage when the sewage does not need to be discharged, and having the characteristics of simple structure, convenient operation and wide applicability.

Those skilled in the art can understand that, for the size of the rainfall, the utility model discloses do not do the restriction, can set for the rainfall parameter threshold according to the actual operation demand and define can.

And when the liquid level is higher than the maximum value of the interval threshold value, the sewage storage can be stopped, namely, the sewage output by the first treatment area 20 is directly input into the sewage discharge pipeline 30 at the moment.

That is, when sewage needs to be regulated, only the sewage output by the first treatment area 20 flows into the second treatment area 40 through gravity for storage, so that only rainwater exists in the sewage discharge pipeline 30, and when sewage needs to be output, only the sewage stored in the second treatment area 40 flows into the sewage discharge pipeline 30 through the first treatment area and the sewage discharge outlet 170, thereby effectively avoiding the technical defects that in the prior art, the sewage directly enters the sewage discharge pipeline for output in the first treatment area 20, the structural design easily causes serious pollution to natural water in rainy days, or the treatment pressure of a sewage treatment facility is too large, the resource is wasted, and the like, and achieving the technical effect of regulating and storing the sewage when the sewage does not need to be discharged, and the sewage treatment facility has the characteristics of simple structure, convenient operation and wide applicability.

As another application environment of the embodiment of the present specification, a regulation node may be set to regulate according to whether a sewage treatment plant has spare capacity, for example, when the sewage treatment plant has no spare capacity, if the sewage output from the first treatment area directly enters the sewage draining pipeline, the treated water is directly conveyed to a sewage treatment plant in the non-rainfall period or is mixed with rainwater and then conveyed to the sewage treatment plant in the rainfall period, so that the treated water entering the sewage treatment plant is excessive to reach the upper treatment limit of the sewage treatment plant, overflow is easy to occur, therefore, the sewage output from the first treatment area 20 can be regulated by the sewage treatment device provided in the embodiment of the present specification, when the sewage treatment plant has surplus capacity, the sewage storage can be stopped, that is, the sewage output from the first treatment area 20 is directly input into the sewage discharge pipe 30.

It should be noted that, the above description of the four application environments of the sewage treatment apparatus in the drainage system provided in the embodiment of the present disclosure is only an example of the actual application of the sewage treatment apparatus, and is not a limitation to the use, and those skilled in the art can also understand that the sewage treatment apparatus provided in the embodiment of the present disclosure may also be applied to other application environments that need to store and store sewage, or a combination of the four application environments, besides the above four application environments, in the drainage system, including other application scenarios that can also be applied to a specific application scenario other than the drainage system, and the present disclosure is not limited thereto. In other words, as long as can realize saving sewage, reach the application environment or the application scene of the technical effect who carries out the regulation to sewage, all be applicable to the utility model discloses a, be in the utility model discloses a within the protection scope.

As an implementation in the examples herein, the first treatment area 20 is a septic tank; the second processing area 40 regulates one of a storage tank, a box culvert and a pipe culvert, which are independent of each other.

As an implementation manner of controlling the circulation of the sewage in the embodiments of the present specification, the sewage treatment apparatus further includes: a flexible shut off device 10 is provided at a location where the trapway 30 communicates with the first treatment region 20.

Specifically, with continued reference to fig. 3-10, the flexible shut off device 10 may include: a flexible sleeve 12 and a valve body 15. Wherein the flexible sleeve 12 has a chamber 11 which can be filled with a filling material; the valve body 15 has a flow passage 151 communicating with the sewage conduit 30, and a slide groove 152 for the flexible sleeve 12 to slide up and down in the valve body 15; the flexible sleeve 12 is disposed within the chute 152 and sealingly connected to the valve body 15. The slide groove 152 communicates with the flow passage 151.

In the embodiment of the flexible shut-off mechanism 10, the flow passage 151 may be understood as a passage for flowing sewage after it is communicated with the sewage pipe 30, and the flexible sleeve 12 may be a flexible bladder having a contraction and expansion function, and the expansion of the bladder is realized by filling the chamber 11 inside the flexible sleeve 12 with filler, or the contraction of the bladder is realized by discharging the filler from the chamber 11 inside the flexible sleeve 12. Meanwhile, the flexible sleeve 12 during expansion or contraction can slide up and down in the sliding groove 152, that is, when the flexible sleeve 12 is expanded, the flexible sleeve slides down to the flow channel 151 from the sliding groove 152 and is attached to the bottom of the flow channel 151, the flow interception is realized; the flexible sleeve 12 slides upwards from the flow channel 151 to the sliding groove 152 when being contracted, and when the flexible sleeve 12 slides upwards to be separated from the bottom of the flow channel 151, the gradual conduction of the flow channel 151 is realized; those skilled in the art will appreciate that such a structure is designed such that the flexible sleeve 12 does not need to be sleeved outside the steel housing as in the prior art, and the flexible sleeve 12 does not need to envelop the whole steel housing, but only the flexible sleeve 12 needs to slide in the sliding groove 152 of the valve body 15 by expansion or contraction, so that the fitting area between the flexible sleeve 12 and the flow passage 151 is greatly reduced, and since the moving area of the expansion or contraction of the flexible sleeve 12 is longitudinally moved relative to the flow passage 151 and does not occupy a transverse space, the flexible sleeve 12 does not need to be transversely installed in the well when being applied to a shunt well, and the flexible sleeve has the characteristic of occupying a very small space.

In addition, in the process of realizing interception, as the flexible sleeve 12 slides downwards to the flow channel 151 through the sliding groove 152 and is attached to the bottom of the flow channel 151 when expanding, the contact sealing between the flexible sleeve 12 and the bottom of the flow channel 151 is surface contact, compared with the point contact in the prior art, the flexible sleeve 12 can achieve a better sealing effect, namely, a better interception effect is achieved, and in order to keep good sealing of the flexible sleeve 12 in the expansion process, the flexible sleeve 12 can be expanded in the expansion state permanently, and the flexible sleeve 12 arranged in the sliding groove 152 is in sealing connection with the valve body 15 in the embodiment.

In particular, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with the filler, which enters the chamber 11 of the closed structure through the open port 121 and forms an expansion inside the chamber, and when the filler needs to be discharged, it is also discharged from the open port 121. It will be appreciated by those skilled in the art that the open port 121 is adapted to, i.e., sized and shaped to correspond to, the slot of the chute 152 such that the open port 121 sealingly engages the slot of the chute 152.

It should be noted that, in the embodiment of the present application, the flexible sleeve 12 is adapted to the shape of the sliding groove 152 and is attached to the inner side wall of the sliding groove 152, the inner side wall of the sliding groove 152 is inclined inward in the direction from one end of the slot to the other end of the sliding groove 152, that is, inclined inward in the vertical direction, and the port diameter of the slot is greater than the port diameter of the other end, it can be understood that the flexible sleeve 12 is the flexible sleeve 12 in the prefabricated shape, the prefabricated shape is adapted to the shape of the sliding groove 152, and the interface of the sliding groove 152 has a certain taper by the inner side wall of the sliding groove 152 being inclined inward in the direction from one end of the slot to the other end of the sliding groove 152, so that the flexible sleeve 12 in the prefabricated shape can be rapidly expanded to the bottom of the flow passage and attached to the bottom of the flow passage during the process of filling the.

Further, in this embodiment of the flexible shut-off mechanism 10, the flexible shut-off mechanism 10 further comprises: a gland 13, the gland 13 being fixed to the slot to seal the open port 121 and the slot; the cover 13 is formed with a through hole 131, and the chamber 11 can be filled or discharged with the filler through the through hole 131. In order to achieve a better sealing effect between the open port 121 and the sliding groove 152, the notch is bent outward in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that two opposite side boundaries of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 fits the bent portion of the notch and extends outward, so that the pressing cover 13 fits the open port 121 extending outward and is bolted (e.g., screwed, bolted, etc.) with the bent portion of the sliding groove 152. This achieves that the open port 121 of the flexible sleeve 12 is completely sealed from the slot by the gland 13 when the slot of the chute 152 is in position. Meanwhile, a reinforcing rib plate 153 is further provided at the bent portion in order to reinforce fastening.

Of course, the notch can also be provided with a flange; the open port 121 is provided with a flange connecting part matched with the flange plate; the gland 13 is attached to the flange connecting part and connected with a flange plate flange, and a reinforcing rib plate 153 is arranged between the flange plate and the notch.

Among them, regarding the distribution manner of the flow passage 151 and the slide groove 152, the flow passage 151 is distributed laterally in the valve body 15, and the slide groove 152 is distributed longitudinally in the valve body 15, that is, the flow passage 151 and the slide groove 152 are perpendicular to each other, and also in order to enhance the fastening, a reinforcing rib plate 153 is provided at a perpendicular intersection portion of the flow passage 151 and the slide groove 152. Of course, it will be understood by those skilled in the art that the vertical distribution of the through-flow channel 151 and the chute 152 relative to each other is not absolute, and in alternative embodiments, when there is a deviation in the vertical direction of the chute 152 relative to the through-flow channel 151, or a distribution that is directly inclined, it is possible to achieve a minimum space occupation without installing it entirely transversely in the well when it is used in a flow splitting well, since its movement zone, which also corresponds to the expansion or contraction of the flexible sheath 12, is moved longitudinally or close to longitudinally relative to the through-flow channel 151, and does not occupy transverse space. Therefore, the distribution of the positions of the flow channels 151 and the chutes 152 is applicable to the embodiments of the present invention, and is within the scope of the present invention.

Further, in order to facilitate quick installation between the circulation channel 151 and the pipeline, in the embodiment of the present application, two ports for externally connecting the pipeline are correspondingly disposed at two ends of the circulation channel 151, and the two ports extend outwards in a circulation direction (i.e., a transverse direction shown in the drawing) of the circulation channel 151 and are correspondingly distributed at two sides of the sliding groove 152. Therefore, the two corresponding interfaces can be connected with an external pipeline through bolts or directly and correspondingly inserted into the external pipeline to be clamped with the external pipeline.

Wherein the flexible sleeve 12 has a chamber 11 which can be filled with a filling material; the valve body 15 has a flow passage 151 for externally connecting a pipe (e.g., a first water inlet or a first water outlet of a flow splitting well), and a slide groove 152 for allowing the flexible sleeve 12 to slide up and down in the valve body 15; the shutter 14 and the flexible sleeve 12 are both disposed within the chute 152; the flashboard 14 is fixedly connected with the flexible sleeve 12, and the flexible sleeve 12 is hermetically connected with the valve body 15; the slide groove 152 communicates with the flow passage 151.

Similarly, the flow passage 151 may be understood as a passage for flowing sewage after it is communicated with the pipe port of the sewage pipe 30, and the flexible sleeve 12 may be a flexible bladder having a contraction and expansion function, and the expansion of the bladder is performed by filling the chamber 11 inside the flexible sleeve 12 with the filler, or the contraction of the bladder is performed by discharging the filler from the chamber 11 inside the flexible sleeve 12. Meanwhile, the flexible sleeve 12 in the expansion or contraction process can slide up and down in the chute 152, and the gate plate 14 is fixedly connected with the flexible sleeve 12, that is, the flexible sleeve 12 drives the gate plate 14 to slide downwards from the chute 152 to the circulation channel 151 when expanding, and when the gate plate 14 is attached to the bottom of the circulation channel 151, the closure is realized; the flexible sleeve 12 drives the shutter plate 14 to slide upwards from the flow channel 151 to the chute 152 when being contracted, and realizes gradual conduction of the flow channel 151 when the shutter plate 14 slides upwards to be separated from the bottom of the flow channel 151; those skilled in the art will appreciate that such a structure is designed such that the flexible sleeve 12 does not need to be sleeved outside the steel housing as in the prior art, and the flexible sleeve 12 does not need to envelop the whole steel housing, but only the flexible sleeve 12 needs to slide in the sliding groove 152 of the valve body 15 by expansion or contraction, so that the fitting area between the flexible sleeve 12 and the flow passage 151 is greatly reduced, and since the moving area of the expansion or contraction of the flexible sleeve 12 is longitudinally moved relative to the flow passage 151 and does not occupy a transverse space, the flexible sleeve 12 does not need to be transversely installed in the well when being applied to a shunt well, and the flexible sleeve has the characteristic of occupying a very small space.

In addition, in the process of realizing closure, because the flexible sleeve 12 drives the gate plate 14 to slide downwards to the circulation channel 151 from the sliding groove 152 and to be attached to the bottom of the circulation channel 151 when expanding, the contact sealing between the gate plate 14 and the bottom of the circulation channel 151 is surface contact, which can achieve better sealing effect compared with the point contact in the prior art, that is, achieve better closure effect, and in order to keep good sealing of the flexible sleeve 12 in the expansion process, the flexible sleeve 12 arranged in the sliding groove 152 can be expanded durably in the expansion state, and in the embodiment, the flexible sleeve 12 is connected with the valve body 15 in a sealing manner.

Similarly, the flexible sleeve 12 has an open port 121, and a chamber 11 of a closed structure is formed by extending the open port 121 inwards, and the open port 121 is matched with the slot of the sliding chute 152 and is connected with the slot of the sliding chute 152 in a sealing way through the open port 121. And the top of the shutter 14 is fixed to the other end of the flexible sleeve 12 opposite the open port 121. In particular, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with the filler, which enters the chamber 11 of the closed structure through the open port 121 and forms an expansion inside the chamber, and when the filler needs to be discharged, it is also discharged from the open port 121. It will be appreciated by those skilled in the art that the open port 121 is adapted to, i.e., sized and shaped to correspond to, the slot of the chute 152 such that the open port 121 sealingly engages the slot of the chute 152.

Further, in an embodiment of the flexible shut-off mechanism, it further comprises: a gland 13, the gland 13 being fixed to the slot to seal the open port 121 and the slot; the cover 13 is formed with a through hole 131, and the chamber 11 can be filled or discharged with the filler through the through hole 131. In order to achieve a better sealing effect between the open port 121 and the sliding groove 152, the notch is bent outward in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that two opposite side boundaries of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 fits the bent portion of the notch and extends outward, so that the pressing cover 13 fits the open port 121 extending outward and is bolted (e.g., screwed, bolted, etc.) with the bent portion of the sliding groove 152. This achieves that the open port 121 of the flexible sleeve 12 is completely sealed from the slot by the gland 13 when the slot of the chute 152 is in position. Meanwhile, a reinforcing rib plate 153 is further provided at the bent portion in order to reinforce fastening.

In this embodiment of the flexible shut-off mechanism, the flow passage 151 is distributed laterally in the valve body 15, the slide groove 152 is distributed longitudinally in the valve body 15, that is, the flow passage 151 and the slide groove 152 are perpendicular to each other, and also in order to enhance the fastening, a reinforcing rib plate 153 is provided at a perpendicular intersection of the flow passage 151 and the slide groove 152. Of course, it will be understood by those skilled in the art that the vertical distribution of the through-flow channel 151 and the chute 152 relative to each other is not absolute, and in alternative embodiments, when there is a deviation in the vertical direction of the chute 152 relative to the through-flow channel 151, or a distribution that is directly inclined, it is possible to achieve a minimum space occupation without installing it entirely transversely in the well when it is used in a flow splitting well, since its movement zone, which also corresponds to the expansion or contraction of the flexible sheath 12, is moved longitudinally or close to longitudinally relative to the through-flow channel 151, and does not occupy transverse space. Therefore, the distribution of the positions of the flow channels 151 and the chutes 152 is applicable to the embodiments of the present invention, and is within the scope of the present invention.

Further, in this embodiment of the flexible shut-off mechanism 10, in order to enable the flexible sleeve 12 to better carry the shutter 14 to move during the expansion or contraction process, it further includes a pressure plate 16, and the pressure plate 16 is fixed in the chamber 11 and located at the bottom of the chamber 11 to fit the top of the shutter 14 and is fixedly connected to the top of the shutter 14, such as by bolts or screws.

As an operation state of the embodiment of the present application, when the chamber 11 is filled with the filler, the flexible sleeve 12 starts to expand until the bottom of the flexible sleeve 12 is attached to the bottom of the flow channel 151 and seamlessly joined with the bottom of the flow channel 151, thereby achieving the flow interception of the flow channel 151.

As a further operating condition of the embodiment of the present application, when the chamber 11 is emptied of the filling material, the flexible sleeve 12 starts to shrink until the bottom of the flexible sleeve 12 is located at the top portion of the through channel 151, thereby achieving a complete communication of the through channel 151.

That is, in the embodiment of the present application, the expansion of the airbag is achieved by filling the chamber 11 inside the flexible sheath 12 with the filler, or the contraction of the airbag is achieved by discharging the filler from the chamber 11 inside the flexible sheath 12. Meanwhile, the flexible sleeve 12 during the expansion or contraction process can slide up and down in the sliding groove 152, that is, the flexible sleeve 12 slides down to the circulation channel 151 from the sliding groove 152 during the expansion, or drives the gate plate 14 to slide down to the circulation channel 151 from the sliding groove 152 and to be attached to the bottom of the circulation channel 151, so that the closure is realized; when the flexible sleeve 12 is contracted, the flexible sleeve slides upwards from the flow channel 151 to the sliding groove 152, and when the flexible sleeve 12 slides upwards to be separated from the bottom of the flow channel 151, or drives the flashboard 14 to slide upwards to be separated from the bottom of the flow channel 151, the gradual conduction of the flow channel 151 is realized; the structure design enables the flexible sleeve not to be sleeved outside the steel outer cover as in the prior art, and the flexible sleeve is not required to envelop the whole steel outer cover, but only needs to be expanded or contracted to slide in the chute of the valve body, so that the joint area of the flexible sleeve and the circulation channel is greatly reduced, when the flexible sleeve is installed in a diversion facility such as a diversion well, the flexible sleeve is only required to be connected with any pipe orifice (a water inlet pipe or a water outlet pipe), and the whole flexible sleeve is not required to be transversely installed in the well, so that the occupied space is extremely small.

In addition, in the embodiment of the present application, the flexible shut-off mechanism 10 may be fixed to the opening portion of the sewage pipe in a flange-type mounting manner through the valve body 15. The flexible intercepting mechanism 10 can also be fixed at the pipe orifice of the sewage pipeline in a wall-attached mounting mode through the valve body 15, and for the flange type or wall-attached specific mounting mode, the mounting mode in the prior art can be adopted, which is not described in detail in this embodiment.

Finally, it is necessary to supplement that the filling material in the embodiment of the present application may be a gas (such as air, nitrogen, inert gas, etc.) or a liquid (such as hydraulic oil, water), etc. Preferably, the filling material is selected from gases, which can be rapidly filled or discharged, so that the flexible sleeve 12 can be rapidly expanded or contracted, and then the technical effect of rapid closure or passing can be achieved.

In the embodiment of the present specification, the whole sewage treatment unit may be a tank structure, the first treatment region 20 and the second treatment region 40 are 2 independent regions of the tank structure (for example, the left side is the first treatment region 20, and the right side is the second treatment region 40), in the first treatment region 20, a plurality of partition plates 70 may be further provided to divide the first treatment region 20 into a plurality of treatment sub-regions, and each partition plate 70 is provided with a water through hole 60 for the circulation of water between the plurality of treatment sub-regions through the water through hole 60.

In this embodiment, the wastewater treatment apparatus includes a conduit 50, the conduit 50 being disposed within the second treatment zone 40; the conduit 50 includes a first conduit opening 501 and a second conduit opening 502. Wherein the conduction pipe 50 is communicated with the first processing area 20 through the first conduction opening 501; the pipe orifice of the first conduction port 501 is higher than the bottom elevation of the sewage discharge pipeline 30; a second via 502 is located at the bottom of the second processing region 40. In this embodiment, when water storage is required, the first valve is closed, the second valve is opened, and the flexible shutoff mechanism 10 is closed, so that as the liquid level of the water in the first treatment area rises, the water in the first treatment area flows into the second treatment area 40 through the conduction pipe 50 under the action of gravity when the water just reaches the pipe orifice level of the first conduction port 501. Since the orifice of the first conduction port 501 is higher than the bottom elevation of the sewage conduit 30, the conduction pipe 50 does not need to be additionally controlled when the water in the first treatment area 20 is normally discharged, and the liquid level of the water in the first treatment area is directly discharged from the sewage conduit 30 when reaching the height of the sewage conduit 30; when the water in the second treatment area needs to be discharged, the first valve is opened and the second valve is closed, the compressed gas is filled into the second treatment area 40 from the gas source to form air pressure in the second treatment area 40, and then the water in the second treatment area 40 is extruded to flow into the first treatment area 20 through the conduction pipe 50, so that the technical effect of regulating and storing the sewage when the sewage is not required to be discharged is achieved, and the device has the characteristics of simple structure, convenience in operation and wide applicability.

For the conduction pipe 50, it may be an "L" shaped structure, and those skilled in the art can understand that the L-shaped structure is only one structural form of the conduction pipe 50, and simple deformation made according to actual conditions in the actual process is also applicable to the present invention, for example, the arc-shaped corner or the L-shaped corner is arc-shaped.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
