Description

Technical Field

[0001] The present invention relates to an artificial wetland, and more particularly to a positioning device for a distribution pipe of a subsurface flow artificial wetland. Background Art

[0002] The subsurface flow artificial wetland introduces sewage through a water distribution system. The water distribution system includes distributed distribution pipes, which are laid on the upper layer of the artificial wetland. The sewage is evenly introduced into the artificial wetland plants and fillers through the orifices on the distribution pipes, so that the sewage can be evenly purified. Due to the large area of the artificial wetland and the distribution pipes being laid on the upper layer of the artificial wetland, it is inevitable that the orifices of the distribution pipes are misaligned and the sewage cannot be evenly distributed, and it is also inevitable that water leakage occurs due to the concentration of uniform stress.

Patent CN108033569A discloses adjusting the height of the internal operating water level of the wetland by controlling the water outlet of different outlet pipes. The overall outlet pipe is connected to the high outlet pipe through a high valve, the overall outlet pipe is connected to the middle outlet pipe through a middle valve, and the overall outlet pipe is connected to the low outlet pipe through a low valve. The height of the internal operating water level of the wetland is adjusted by controlling the water outlet of different outlet pipes, and at the same time, the root growth control and induction of the wetland plants are realized through the reasonable change of the water level.

[0004] The above patents disclose methods for regulating the water level of the wetland and cannot solve the problem of adjusting the distribution pipes of the water distribution system. In view of the above technical problems, the present invention is specifically introduced. Summary of the Invention

[0006] To achieve the above object, the present invention provides a positioning device for a sub-surface flow constructed wetland water distribution pipe. The constructed wetland includes a plurality of wetland units, each wetland unit including a frame body. The water distribution pipe is arranged above the frame body and is connected to the frame body through the positioning device. The positioning device includes: a mounting part, an adjusting part, and a fixing part. The mounting part is opened on the frame body, the adjusting part is accommodated in the mounting part, the adjusting part supports the water distribution pipe, and the fixing part is used to fix the water distribution pipe in the mounting part so as to fix the water distribution pipe on the frame body. The water distribution pipe positioning device of the present invention solves the problems of positioning and adjustment of the water distribution pipe, improves the stability of water distribution, avoids the orifice blockage caused by the misalignment of the orifice of the water distribution pipe, and also avoids the water leakage phenomenon caused by the local stress of the water distribution pipeline, meeting the uniformity and adjustability of water distribution of the water distribution system.

[0007] A further improvement of the present invention to the above solution is that: the adjusting part includes an outer side surface and an inner side surface. The outer side surface is attached to the mounting part; the inner side surface includes a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface form a first included angle α, and the opening direction of the first included angle α faces the joint surface between the adjusting part and the water distribution pipe; the first inclined surface and the second inclined surface are attached to the outer circular surface of the water distribution pipe, so that the water distribution pipe sinks relative to the frame body, and the distance between the top of the water distribution pipe and the end surface of the frame body is ε.

[0008] Further, the adjusting part has an opening width A, the outer circular surface of the water distribution pipe has a diameter D, and the distance ε of the water distribution pipe is determined by the diameter D of the water distribution pipe, the opening width A, and the first included angle α.

[0009] Further, the distance

[0010] Further, the range of the first included angle α is 30° - 150°.

[0011] Further, the outer side surface of the adjusting part is any one of U-shaped, V-shaped, and inverted trapezoidal, and the mounting part is a slot structure, and the cross-section of the slot is any one of U-shaped, V-shaped, and trapezoidal, so that the mounting part is attached to the outer side surface.

[0012] Further, the frame body includes a bottom plate and side plates. The mounting part is opened above the side plates, and the distance ε between the water distribution pipe and the end surface of the frame body is the distance between the top side of the water distribution pipe and the end surface of the side plates.

[0014] Further, the fixing part is an arc-shaped buckle, and the arc-shaped buckle is fixed above the side plates through fixing holes above the side plates to fix the water distribution pipe in the mounting part.

[0015] On the other hand, the present invention also provides a method for adjusting a positioning device of a subsurface flow constructed wetland water distribution pipe, including any one of the above-mentioned positioning devices. In the vertical direction Z, the distance between the top of the water distribution pipe and the end face of the frame body is adjusted by the adjusting part to adjust the rise or fall of the water distribution pipe. The adjusting part can be set as the first adjusting part and the second adjusting part with at least two specifications. The first included angle α of the first adjusting part is smaller than the first included angle α of the second adjusting part. When the first adjusting part is replaced with the second adjusting part, the value of the distance ε becomes smaller. During the construction process, for the possible error problems in the construction of the water distribution pipe during the splicing of multiple modular wetlands, a pre-plan can be made, and adjusting parts with multiple specifications can be set, and by quickly replacing the adjusting parts, the problem of quickly adjusting the height of the water distribution pipe can be solved.

[0016] Furthermore, the adjusting part is provided with three specifications and also includes a third adjusting part. The first included angle α of the third adjusting part is greater than the first included angle α of the second adjusting part. When the second adjusting part is replaced with the third adjusting part, the value of the distance ε becomes smaller.

[0017] Furthermore, at the initial installation position, the water distribution pipe is supported by the second adjusting part. When it is necessary to adjust the water distribution pipe upward along the vertical direction Z, the second adjusting part is replaced with the first adjusting part; when it is necessary to adjust the water distribution pipe downward along the vertical direction Z, the second adjusting part is replaced with the third adjusting part.

[0018] Applying the technical solution of the present invention, at least the following beneficial effects are achieved:

[0040] The subsurface flow constructed wetland evenly introduces sewage into the root systems of wetland plants and the pores of the packing through the orifices of the distribution pipe 3 of the water distribution system. In order to achieve good sewage purification effects, it is required that the distribution pipe 3 of the water distribution system can distribute water evenly. The present invention provides a positioning device for the distribution pipe 3, which solves the problems of positioning and adjustment of the distribution pipe 3, improves the stability of water distribution height, avoids orifice blockage caused by the misalignment of the orifices of the distribution pipe 3, and also avoids water leakage caused by local stress of the water distribution pipe 3, meeting the uniformity and adjustability of water distribution of the water distribution system.

[0041] As Figures 1 - 2 shown, the constructed wetland is formed by splicing and assembling wetland units 1, and the crisscross distribution pipes 3 form the water distribution system of the constructed wetland. The wetland unit 1 includes a frame 2, and a distributed water distribution pipe 3 is supported above it. The distribution pipe 3 is connected and fixed to the distribution pipe 3 through a positioning device, and the positioning device can adjust the height of the distribution pipe 3 in the vertical direction Z. A plurality of positioning devices are adopted in the constructed wetland, and the height of the distribution pipe 3 on different wetland units 1 is adjusted according to the installation conditions at the construction site, ensuring the uniformity of water distribution of the entire water distribution system and also avoiding the phenomenon of stress concentration in local pipes.

[0042] As Figures 3 - 5As shown in the figure, the positioning device of the present invention is based on the modular prefabricated constructed wetland unit 1. The positioning device includes: a mounting part 6, an adjusting part 5, and a fixing part 4. The mounting part 6 is opened on the frame 2, and its internal space accommodates the adjusting part 5, forming a structure in which the adjusting part 5 is embedded in the frame 2. The adjusting part 5 is used to support the water distribution pipe 3, and the water distribution pipe 3 is fixed in the mounting part 6 through the fixing part 4, so as to fix the water distribution pipe 3 on the frame 2.

[0043] The positioning device sets a hollowed-out card slot on the upper side of the side plate as the mounting part 6. The cross-section of the card slot is any one of U-shaped, V-shaped, and trapezoidal. Figure 4 The schematic diagram of the U-shaped card slot is shown. After the adjusting part 5 is installed in the mounting part 6, it is fixed in the mounting part 6 by bolts or card slots, and then the water distribution pipe 3 is wrapped and fixed in the mounting part 6 and the fixing part 4 through the fixing part 4 above the water distribution pipe 3. The fixing part 4 is an arc-shaped buckle, and its two sides are respectively fixedly connected to the side plate through fixing forms such as fixing holes and screws. The combination of the card slot and the arc-shaped buckle connected to the side plate forms a positioning device to wrap the pipeline, which can improve the flatness and stability of pipeline positioning.

[0044] The installation methods of the card slot and the arc-shaped buckle of the present invention can correspond to pipelines of all common diameters in constructed wetlands, and the stability of pipeline installation can be achieved by setting the size of the arc-shaped buckle. In addition, during the actual construction process, due to problems such as ground level and errors, the water distribution pipe 3 may be uneven in height. In order to solve the problem of adjusting the height of the water distribution pipe 3, the height of the water distribution pipe 3 can be finely adjusted by setting different adjusting parts 5.

[0045] The adjusting part 5 includes an outer side surface and an inner side surface. The outer side surface cooperates with the mounting part 6, and the inner side surface is used to support the water distribution pipe 3. As Figures 5 - 7 shown, the outer side surface of the first embodiment of the adjusting part 5 is U-shaped, the outer side surface of the second embodiment is V-shaped, and the outer side surface of the third embodiment is trapezoidal, which fits the mounting part 6 of the corresponding shape. The inner side surface is in the structure form of a double inclined plane, such as V-shaped or trapezoidal, forming a placement area for the water distribution pipe 3, which fits the outer circular surface of the water distribution pipe 3, so that the water distribution pipe 3 sinks relative to the frame 2, and the distance between the top of the water distribution pipe 3 and the end surface 7 of the frame is ε. The double inclined plane includes a first inclined plane 51 and a second inclined plane 52, forming a first included angle α, and its opening direction faces the joint surface of the adjusting part 5 and the water distribution pipe 3. Preferably, the first inclined plane 51 and the second inclined plane 52 are symmetric structures.

[0046] The water distribution pipe 3 is positioned on the frame 2 of the wetland unit 1 through the double inclined plane. The frame 2 includes a bottom plate and side plates. The side plate has a top surface, and the mounting part 6 penetrates the top surface of the side plate and depresses downward from the end surface of the side plate. Part of the water distribution pipe 3 is accommodated in the double inclined plane of the adjusting part 5, and the formed distance ε is the distance between the top of the water distribution pipe 3 and the end surface of the side plate, that is, the distance ε between the water distribution pipe 3 and the end surface 7 of the frame is the distance between the top side of the water distribution pipe 3 and the end surface of the side plate.

[0047] The value of the distance ε of the water distribution pipe 3 is related to the opening width A of the adjusting part 5, the outer diameter D of the outer circular surface of the water distribution pipe 3, and the value of the first included angle α. Specifically, it can be calculated in three different cases for the distance ε.

[0048] In the first case, when the center of the water distribution pipe 3 is above the end face of the side plate, the distance As Figure 3 shown.

[0049] In the second case, when the center of the water distribution pipe 3 is below the end face of the side plate, but the water distribution pipe 3 is not completely accommodated in the adjusting part 5, the distance As Figure 9 shown.

[0050] In the third case, when the water distribution pipe 3 is completely accommodated in the adjusting part 5, the distance As Figure 10 shown.

[0051] Among them, the numerical range of the first included angle α can be determined according to the specific construction situation, and its numerical range can be 0 - 180°, and the preferred range is 30° - 150°.

[0052] The present invention also provides a method for adjusting the positioning device of the subsurface flow constructed wetland water distribution pipe 3, including the above-mentioned positioning device. As Figure 8 shown, in the vertical direction Z, the adjusting part 5 is used to adjust the distance between the top of the water distribution pipe 3 and the end face 7 of the frame body to adjust the rise or fall of the water distribution pipe 3. The adjusting part 5 can be set as the first adjusting part and the second adjusting part with at least two specifications. The values of the first included angle α of the first adjusting part and the second adjusting part are different. The first included angle α of the first adjusting part is less than the first included angle α of the second adjusting part. When the first adjusting part is replaced with the second adjusting part, the value of the distance ε becomes smaller.

[0053] The following takes the water distribution pipe 3 provided with three different specifications of the adjusting part 5 for illustration. It also includes a third adjusting part. The first included angle α of the third adjusting part is greater than the first included angle α of the second adjusting part. When the second adjusting part is replaced with the third adjusting part, the value of the distance ε becomes smaller. For example, the first included angle α of the first adjusting part can take a value of 30°, the first included angle α of the second adjusting part takes a value of 45°, and the first included angle α of the third adjusting part takes a value of 80°.

[0054] If the sag value of the water distribution pipe 3 when using the second adjustment part is taken as the reference, when changing from the second adjustment part to the first adjustment part, the water distribution pipe 3 is adjusted upward along the vertical direction Z; when changing from the second adjustment part to the third adjustment part, the water distribution pipe 3 is adjusted downward along the vertical direction Z. By locally adjusting the height of the distributed water distribution pipe 3, the water distribution system above the artificial wetland can be adjusted as a whole, making the water distribution of the water distribution system more uniform and avoiding problems such as stress concentration in local pipes or blockage of the orifices on the water distribution pipe 3.

[0055] At the initial installation position, the water distribution pipe 3 is supported by the second adjustment part. When the water distribution pipe 3 needs to be adjusted upward along the vertical direction Z due to errors during construction, etc., the second adjustment part is replaced with the first adjustment part; when the water distribution pipe 3 needs to be adjusted downward along the vertical direction Z, the second adjustment part is replaced with the third adjustment part. After the adjustment part 5 is replaced, the annular buckle is fixed on the side. By replacing different adjustment parts 5, fine adjustment of the height of the water distribution pipe 3 along the vertical direction Z is achieved, thus solving the problem that the height of the water distribution pipe 3 on the upper part of the modular prefabricated wetland unit 1 cannot be adjusted or is inconvenient.

[0056] According to actual needs, the adjustment part 5 can also be set to more specifications, such as the first adjustment part, the second adjustment part, the third adjustment part, the fourth adjustment part, etc., to more precisely adjust the height of the water distribution pipe 3. During the construction process, for the possible error problems in the erection of the water distribution pipe 3 during the splicing of multiple modular wetlands, a pre-plan can be made, and multiple specifications of the adjustment part 5 are set. By quickly replacing the adjustment part 5, the rapid adjustment of the height of the water distribution pipe 3 can be realized.

[0057] In summary, from the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0058] 1. The present invention forms a positioning device by combining a double inclined plane and an annular buckle connected to the side to wrap the pipeline. On the one hand, it can level the height of the water distribution pipe 3, and on the other hand, it can also realize fine adjustment of the height of the water distribution pipe 3, greatly improving the stability of the pipeline.

[0059] 2. During the construction process, for the possible error problems in the erection of the water distribution pipe 3 during the splicing of multiple modular wetlands, a pre-plan can be made, and multiple specifications of the adjustment part 5 are set. By quickly replacing the adjustment part 5, the problem of rapid adjustment of the height of the water distribution pipe 3 can be realized.

[0060] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
