Description

Technical Field

[0001] The invention relates to the technical field of drainage equipment, and in particular to a flexible flow diversion device and a pipe network system having the flexible flow diversion device. Background Art

[0002] The urban pipe network is divided into a combined sewer system and a separate sewer system, which are used to discharge sewage (such as domestic sewage) within the unit area. In the existing discharge process, the sewage in the unit area is first transported to the septic tank through the sewage branch pipe for collection and chemical treatment (such as chemical decomposition in the septic tank), so that the treated upper layer liquid flows into the municipal pipe network through the sewage pipe for subsequent treatment.

[0003] However, this discharge method causes the discharged sewage to directly enter the sewage pipe and mix with rainwater. If the mixed water of rainwater and sewage is directly discharged into natural water bodies on rainy days, it is very easy to cause serious pollution to the receiving water bodies. If it is directly discharged into sewage treatment facilities for treatment, a large amount of relatively clean rainwater on rainy days will enter the sewage treatment facilities for unnecessary treatment, resulting in a waste of resources.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] (1) The present invention can control the flexible sleeve to be in a deflated state on sunny days, that is, the pipe mouth of the sewage interception pipe is connected at this time, so that the sewage input by the water inlet pipe is directly discharged to the downstream sewage treatment facility through the sewage interception pipe for treatment. In the early stage of rainy days, the flexible sleeve can still be controlled to be in a deflated state, that is, the pipe mouth of the sewage interception pipe is connected at this time, so that the sewage input by the water inlet pipe continues to be discharged to the downstream sewage treatment facility through the sewage interception pipe for treatment. In the middle and late stages of rainy days, the flexible sleeve can be controlled to be in an inflated state, that is, the pipe mouth of the sewage interception pipe is closed at this time, so that the sewage input by the water inlet pipe is discharged to the natural water body through the outlet pipe. It effectively avoids the technical defects of the sewage discharge design in the prior art, such as it is very easy to cause serious pollution to natural water bodies on rainy days, or the sewage treatment facility has excessive treatment pressure and waste of resources. It has the characteristics of simple structure, convenient operation and wide applicability.

[0025] (2) In the present invention, the main body, water inlet pipe, water outlet pipe and sewage interception pipe are integrally formed, which reduces the floor space compared with separate independent designs. In addition, the entire diversion device can be integrated, installed and debugged in the factory and shipped to the site for installation after passing the test, which greatly saves construction and installation time and has the characteristics of low cost.

[0026] (3) The present invention adopts a switch structure of a flexible sleeve, and a pressure chamber is arranged in the flexible sleeve. The entire flexible sleeve is an integrated structure. Compared with the prior art, there is no problem of sealing the pressure chamber, the structure is simpler, and it is easy to install and use.

[0027] (4) An independent pressure-charging chamber or two independent pressure-charging chambers are arranged in the flexible sleeve of the present invention. In addition to the traditional function of closing the flow channel, the flexible sleeve also has a flow-blocking function. Only the lower pressure-charging chamber can be pressurized. The inner rubber layer of the lower pressure-charging chamber bulges upward. The lower half of the flexible sleeve after inflation and deformation is equivalent to an adjustable weir with an adjustable height. When the water level rises above the flow-blocking height, water can overflow from above. In this way, the accumulated mud at the bottom of the pipeline or the accumulated mud in the diversion well can be intercepted to prevent the accumulated mud at the bottom from entering the natural water body with rainwater and polluting the natural water body. In addition, when used at the drain outlet, the flow-blocking height of the lower half of the flexible sleeve can be adjusted according to the natural water level to prevent the backflow of natural water bodies. While preventing backflow, the overflow from the top of the lower half of the flexible sleeve does not affect the flow of floods. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Example 1

[0048] See also Figures 1 to 18 As shown, a flexible diversion device provided by an embodiment of the present invention comprises: a body 5 and a sewage interception pipe 6. The body 5 is correspondingly connected to at least one water inlet pipe 51 and at least one water outlet pipe 52; the sewage interception pipe 6 is connected to the body 5, and a flexible sleeve 1 for controlling the opening or closing of the pipe mouth of the sewage interception pipe 6 is provided at the part where the sewage interception pipe 6 and the body 5 are connected. The outer wall of the flexible sleeve 1 is in contact with the inner wall of the pipe mouth of the sewage interception pipe 6, and at least one independent pressure chamber 11 is provided in the flexible sleeve 1. The flexible sleeve 1 at the position where each pressure chamber 11 is located has an outer rubber layer 12 and an inner rubber layer 13; the outer rubber layer 12 of each pressure chamber 11 is provided with an inlet and outlet hole, and the inlet and outlet hole is connected to the pressure chamber 11; in the present invention, the body 5, the water inlet pipe 51, the water outlet pipe 52 and the sewage interception pipe 6 are integrally formed.

[0049] Specifically, in the embodiment of the present invention, on sunny days, the flexible sleeve 1 can be controlled to be in a deflated state, that is, the pipe mouth of the sewage interception pipe 6 is connected at this time, so that the sewage input by the water inlet pipe 51 is directly discharged to the downstream sewage treatment facility through the sewage interception pipe for treatment. In the early stage of rainfall on rainy days, the flexible sleeve 1 can still be controlled to be in a deflated state, that is, the pipe mouth of the sewage interception pipe 6 is connected at this time, so that the sewage input by the water inlet pipe 51 continues to be discharged to the downstream sewage treatment facility through the sewage interception pipe 6 for treatment. In the middle and late stages of rainfall on rainy days, the flexible sleeve 1 can be controlled to be in an inflated state, that is, the pipe mouth of the sewage interception pipe 6 is closed at this time, so that the sewage input by the water inlet pipe 51 is discharged to the natural water body through the outlet pipe 52. It effectively avoids the technical defects of the sewage discharge design in the prior art, such as the serious pollution of natural water bodies on rainy days, or the excessive pressure of sewage treatment facilities and waste of resources, and has the characteristics of simple structure, convenient operation and wide applicability. In addition, this embodiment integrates the main body 5, the water inlet pipe 51, the water outlet pipe 52 and the sewage interception pipe 6 into one piece, which reduces the floor space compared with separate independent designs, and the entire diversion device can be integrated, installed and debugged in the factory, and can be shipped to the site for installation after passing the inspection, which greatly saves the construction and installation time and has the characteristics of low cost.

[0050] As for the pipe elevations of the sewage intercepting pipe 6 and the outlet pipe 52, there are multiple pipe elevation relationships in this embodiment. For example, as one relationship, the pipe top elevation of the sewage intercepting pipe 6 is less than or equal to the pipe bottom elevation of the outlet pipe 52; as another relationship, the pipe bottom elevation of the sewage intercepting pipe 6 is greater than or equal to the pipe bottom elevation of the outlet pipe 52; as another relationship, the pipe bottom elevation of the sewage intercepting pipe 6 is less than the pipe bottom elevation of the outlet pipe 52, and the pipe top elevation of the sewage intercepting pipe 6 is greater than or equal to the pipe bottom elevation of the outlet pipe 52. In the actual operation process, it can be flexibly set and selected according to the construction environment and conditions on site, and has the characteristics of wide applicability. At the same time, in the embodiment of the present invention, in order to achieve the effect of controlling the flow rate and achieving overflow of the sewage flowing in from the water inlet pipe 51, a weir plate 53 is also provided in the body 1, and the water inlet pipe 51 and the sewage intercepting pipe 6 are located on one side of the weir plate 53, and the outlet pipe 52 is located on the other side of the weir plate 53. In this way, when sewage flows in from the water inlet pipe 51, the sewage is first blocked by the weir plate 53, so that the sewage flowing into the body is first intercepted by the sewage interception pipe after reaching a certain liquid level, and as the liquid level continues to rise to reach the height of the weir plate 53, it overflows to the side connected to the outlet pipe 52. Of course, in the embodiment of the present invention, a flexible sleeve 1 or a flexible sleeve 2 for controlling the conduction or closing of the outlet pipe 52 can also be provided at the pipe mouth of the outlet pipe 52. Fig.18 As for the downward opening weir gate 8 shown, those skilled in the art can understand that whether to set a flexible sleeve 1 or a downward opening weir gate 8 at the pipe mouth of the water outlet pipe 52 can be flexibly selected according to actual conditions and is not limiting. In other words, whether to set a flexible sleeve 1 or a downward opening weir gate 8 at the pipe mouth of the water outlet pipe 52 is applicable to the present invention and is within the protection scope of the present invention.

[0051] The main body 5 in the embodiment of the present invention may be a well structure, and then the well structure, the water inlet pipe 51, the water outlet pipe 52 and the sewage interception pipe 6 form a diversion well with a diversion function.

[0052] For the flexible sleeve 1 in the embodiment of the present invention, the flexible sleeve 1 is provided with a through-flow channel 10, the flexible sleeve 1 is an integrated structure, and at least one independent pressure chamber 11 is arranged in the flexible sleeve 1, and the flexible sleeve 1 at the position where each of the pressure chambers 11 is located has an outer rubber layer 12 and an inner rubber layer 13; the outer rubber layer 12 of each of the pressure chambers 11 is provided with an inlet and outlet hole, and the inlet and outlet hole is connected with the pressure chamber 11; the mounting structure includes two limiting parts 2, and the two limiting parts 2 are fixed at both ends of the flexible sleeve 1 to clamp the flexible sleeve 1. The rubber structure forming the pressure chamber 11 in this embodiment is an integrated structure with the rubber structure at other positions. Since the flexible sleeve 1 does not form the pressure chamber 11 together with other components, there is no need to set a sealing structure for sealing the pressure chamber 11 to prevent leakage of the pressure chamber 11. The structure is simple, easy to install, and has a wide range of applications. The flexible sleeve 1 is only fixed at both ends, and no mounting structure is set on the tube body of the flexible sleeve 1, which is convenient to disassemble, and easy to install and maintain.

[0053] Preferably, as a specific implementation, please refer to Figure 2-9 , the structure of the flexible sleeve 1 has the following forms:

[0054] The flexible sleeve 1 has a first structural form. In this embodiment, the flexible sleeve 1 is cylindrical, and the pressure chamber 11 in the flexible sleeve 1 is also cylindrical. The flexible sleeve 1 is provided with an inlet and outlet hole. The pressure chamber 11 is pressurized through the inlet and outlet hole, the flexible sleeve 1 is deformed, and the flow channel 10 is cut off. The pressure chamber 11 is pressurized through the inlet and outlet hole, the flexible sleeve 1 recovers its deformation, and the flow channel 10 is connected.

[0055] The second structural form of the flexible sleeve 1 is that the cross-sectional shape of the flexible sleeve 1 is circular. When a pressure chamber 11 is set, the pressure chamber 11 is a lower pressure chamber 111. The cross-sectional shape of the lower pressure chamber 111 is arc-shaped. The arc length of the cross-sectional area of ​​the lower pressure chamber 111 is smaller than the circumference of the flexible sleeve 1 at the cross-sectional area. The flexible sleeve 1 at the position of the lower pressure chamber 111 has an outer rubber layer 12 and an inner rubber layer 13, and the outer rubber layer 12 and the inner rubber layer 13 and the flexible sleeve 1 outside the pressure chamber 11 are an integral structure, wherein the arc length of the lower pressure chamber 111 can account for one-half or two-thirds of the circumference of the entire flexible sleeve 1. Different specifications can be designed according to different interception heights. The higher the interception height, the more the arc length of the lower pressure chamber 11 approaches the circumference of the flexible sleeve. The outer rubber layer 12 of the lower pressure chamber 111 is provided with an inlet and outlet hole, which is connected to the pressure chamber 11. When pressurized through the inlet and outlet holes, the inner rubber layer 13 on the side where the lower pressure chamber 111 is located rises to a certain height, which is equivalent to a weir with adjustable height. When the inner rubber layer 13 fits the inner wall of the upper flexible sleeve 1, the flow channel 10 is cut off. When the inner rubber layer 13 of the lower pressure chamber 111 in the lower part of the structure rises to a certain height, the top space can overflow, which can block part of the mud and sand garbage from entering the downstream, and can also prevent backflow when the water level in the downstream is too high.

[0056] The flexible sleeve 1 has a third structural form, in which the flexible sleeve 1 is provided with two independent pressure chambers 11, namely an upper pressure chamber 110 and a lower pressure chamber 111. The upper pressure chamber 110 and the lower pressure chamber 111 are respectively arranged on the upper and lower sides of the flexible sleeve 1. The outer rubber layer 12 on the side where the upper pressure chamber 110 is located is arranged at the upper inlet and outlet hole connected to the upper pressure chamber 110, and the outer rubber layer 12 on the side where the lower pressure chamber 111 is located is arranged at the lower inlet and outlet hole connected to the lower pressure chamber 111.

[0057] The fourth structural form of the flexible sleeve 1 is to set three independent pressure chambers 11, which are divided into three parts along the circumference of the flexible sleeve 1, and each flexible sleeve 1 is provided with a pressure chamber 11; or, to set four independent pressure chambers 11, which are divided into four parts along the circumference of the flexible sleeve 1, and each flexible sleeve 1 is provided with a pressure chamber 11, and each pressure chamber 11 is provided with an inlet and outlet hole. As a preferred embodiment, the flexible sleeve 1 should be divided into three or four equal parts to ensure that the inner rubber layer of each flexible sleeve 1 has the same deformation and pressure, which is convenient for control. A relatively large-sized flexible sleeve 1, if one or two half-structures are relatively deformed to cut off the flow channel 10, if the diameter of the flow channel 10 is large, the deformation of the flexible sleeve 1 on the upper and lower sides is large, and the required pressure is large, not only the sealing effect is not good, the flow channel 10 cannot achieve zero leakage, and there is a safety hazard of explosion. By using the three-way or four-way deformation of the present embodiment to close the flow channel, the inner rubber layer of each independent pressurized chamber has a small deformation, and the required pressure is small, which is safe and reliable, has a good sealing effect, and has a wide range of uses.

[0058] Further preferably, the inlet and outlet holes in this embodiment can be two holes, an inlet hole and an outlet hole, arranged on the outer rubber layer 12, or can be one hole arranged on the outer rubber layer 12, and an inlet pipeline and an outlet pipeline are arranged on the delivery pipeline connected to the hole.

[0059] Further preferably, in this embodiment, the limiting portion 2, see Figure 10-12As shown, it can be understood that among the two limiting parts 2, one of the limiting parts 2 includes a pressing plate 41 and a first fixing ring 421, the first fixing ring 421 is a metal ring with an annular structure, which is embedded in one end of the flexible sleeve 1, and a mounting hole is provided on the pressing plate 41. When installing, one end of the expansion bolt can be passed through the mounting hole to fix it at the pipe mouth of the pipeline, and at the same time, the pressing plate 41 presses against one end of the flexible sleeve to fix one end of the flexible sleeve 1 at the pipe mouth of the pipeline. The other limiting part 2 includes a second fixing ring 422, which is a metal ring with an annular structure and is embedded in the other end of the flexible sleeve 1. Those skilled in the art can understand that in the structural mode of this limiting portion 2, the flexible sleeve 1 can be directly inserted into the existing pipeline for direct installation, with a simple structure and a small installation space. In order to ensure that the outer wall of the flexible sleeve 1 can contact the inner wall of the pipeline more closely, an outer cover body 44 is also provided in the present embodiment. The outer cover body 44 is sleeved on the outer portion of the flexible sleeve 1 and is located between the outer wall of the flexible sleeve 1 and the interior of the pipeline, so that the installation of the flexible sleeve 1 in the pipeline is more stable. At the same time, the first fixing ring 421 and the second fixing ring 422 can respectively support the two ends of the flexible sleeve 1, and the first fixing ring 421 and the second fixing ring 422 can be integrated into the flexible sleeve, or can be made detachable and installed separately, so as to achieve the technical effect of simple installation and maintenance and easy operation.

[0060] Furthermore, in this embodiment, a dirt blocking portion 43 with a raised structure may be provided on one end and / or the other end of the flexible sleeve 1 to prevent pollutants such as sludge and residue in the pipeline from flowing into the gap between the flexible sleeve 1 and the outer cover body 44 and causing additional cleaning and maintenance costs.

[0061] Of course, the structural mode of the above-mentioned limiting portion 2 is only one implementation mode of the installation structure in the flexible sleeve with the installation structure. Similarly, the structural forms one, two and three of the flexible sleeve 1 are only multiple implementation modes of the flexible sleeve. Those skilled in the art can understand that any combination of the limiting portion 2 and the multiple implementation modes of the flexible sleeve 1, resulting in several types of flexible sleeves with installation structures, are all suitable for the present invention and are within the protection scope of the present invention. Other combinations not included in the embodiments of the present invention cannot be excluded on the grounds that the embodiments of the present invention do not exhaust all combinations.

[0062] As a supplementary embodiment of the first embodiment of the present application, on the basis of the first embodiment of the present application, the first embodiment provided by the present application also includes an air-filling and air-discharging device, a rain gauge and a controller. Among them, the rain gauge is connected to the controller signal for monitoring the rainfall signal, and the controller is used to control the air-filling and air-discharging device to inflate or deflate the flexible sleeve 1 according to the rainfall signal. As a control method of the controller, it can be: when a sunny day or an initial rainfall signal is monitored, the air-filling and air-discharging device is controlled to deflate the flexible sleeve, at which time the pipe mouth of the sewage interception pipe is in a conducting state, and at this time, the sewage on a sunny day flows into the downstream sewage treatment facility through the water inlet pipe, the main body and the sewage interception pipe in turn for treatment; when a mid-to-late rainfall signal is monitored, the air-filling and air-discharging device is controlled to inflate the flexible sleeve, at which time the pipe mouth of the sewage interception pipe is in a closed state, and the sewage flows directly into the downstream natural water body through the water inlet pipe, the main body and the water outlet pipe in turn.

[0063] Furthermore, the first embodiment of the present invention may also include a liquid level meter for monitoring the liquid level signal in the main body 5. The controller receives the liquid level signal transmitted by the liquid level meter and the rainfall signal monitored by the above-mentioned rain gauge, and comprehensively controls the inflation and deflation action of the inflation and deflation device. As a control method of the controller, it may be: when the rainfall does not reach the set threshold, the controller controls the inflation and deflation device to deflate the flexible sleeve to the pipe opening of the sewage interception pipe; or, when the rainfall reaches the set threshold, the controller controls the inflation and deflation device to inflate the flexible sleeve to the pipe opening of the sewage interception pipe to close; or, when the rainfall reaches the set threshold and the liquid level signal reaches the set threshold, the controller controls the inflation and deflation device to deflate the flexible sleeve to the pipe opening of the sewage interception pipe.

[0064] Those skilled in the art can understand that the control method of the above-mentioned controller is only an exemplary control method of the first embodiment of the present invention and is not limited thereto. Those skilled in the art can make adaptive adjustments or modifications to the control method according to actual operating conditions. The present embodiment does not limit this and it can be understood that it is still within the scope of application and protection of this application.

[0065] Furthermore, the first embodiment may also include a solar power supply device 7, which is connected to the gas charging and discharging device, the rain gauge, the liquid level meter and / or the controller to supply power to each device.

[0067] On the basis of Example 1, this Example 2 provides a pipeline, in which the flexible sleeve 1 of Example 1 is installed in the pipe opening of the pipeline;

[0068] The outer wall of the flexible sleeve 1 fits with the inner wall of the pipe mouth of the pipeline, the limiting parts 2 of the mounting structure are fixed on the inner walls of the pipe mouth of the pipeline at both ends of the flexible sleeve 1, and the flexible sleeve 1 is clamped between the limiting parts 2.

[0069] Or as another variation of a pipe, a flexible sleeve with a mounting structure of Example 1 is installed in the pipe mouth of the pipe; the outer wall of the flexible sleeve 1 is fitted with the inner wall of the pipe mouth of the pipe through the outer cover body 44, the limiting portion 2 of the mounting structure is fixed at the pipe mouth of the pipe, and is pressed against one end of the flexible sleeve 1 through a pressure plate, and one end of the flexible sleeve 1 is supported by an embedded first fixing ring, and a second fixing ring is also embedded in the other end of the flexible sleeve 1, and the other end of the flexible sleeve 1 is supported by the second fixing ring.

[0070] The structure of the flexible sleeve 1 in this embodiment is to select the interception height according to the use. The lower pressure chamber 111 is pressurized to a certain height. At this time, the height of the inner rubber layer of the lower pressure chamber 111 is equivalent to a weir with adjustable height. When the pressure is large, the bulge height is high and the interception height is also high. When the pressure is small or after the pressure is released, the bulge height is low and the interception height is also low. The pressure can be controlled according to the actual use. When the water level rises above the interception height, water can overflow from above. In this way, the mud at the bottom of the pipeline or the mud in the diversion well can be intercepted to prevent the mud at the bottom from entering the natural water body with rainwater and polluting the natural water body. In addition, when used at the drain outlet, the interception height of the lower half of the flexible sleeve can be adjusted according to the natural water level to prevent the backflow of natural water bodies. While preventing backflow, the overflow from the top of the lower half of the flexible sleeve does not affect the flood discharge.
