Description
本発明は、本管の内部に位置する複数の管状体を支持するための管状体支持ユニットに関する。 The present invention relates to a tubular body support unit for supporting a plurality of tubular bodies located inside a main pipe.
工場などの施設から流れ出る排水は、下水管などの本管を通じて処理場などの排出先へ流される。近年、施設などから排出されたエネルギーを再利用する技術として、排水が有する熱量を他の媒体に伝達する技術が開発されている。排水が有する熱量の伝達に際しては、例えば、本管の内部に複数の管状体が配置されて、熱量を受けるための媒体が各管状体の内部に流される(例えば、特許文献1参照)。 Wastewater flowing out from facilities such as factories is discharged to a discharge place such as a treatment plant through a main pipe such as a sewer pipe. In recent years, as a technique for reusing energy discharged from facilities and the like, a technique for transferring the amount of heat of wastewater to another medium has been developed. When the amount of heat contained in the wastewater is transferred, for example, a plurality of tubular bodies are arranged inside the main pipe, and a medium for receiving the amount of heat is flown into each tubular body (see, for example, Patent Document 1).
ところで、本管の内部に位置する各管状体は、本管の内部を流れる排水に押圧されて、排水の流れる方向や管状体の形状に基づく方向などの様々な方向に向けて動く。こうした押圧による管状体の位置のずれは、熱量の伝達される効率、ひいては、エネルギーの再利用される効率を低下させるため、上述した技術においては、本管の内部で各管状体の位置がずれることを抑える技術が望まれている。
本発明は、本管の内部で管状体の位置のずれを抑えることを可能とした管状体支持ユニットを提供することを目的とする。
By the way, each tubular body located inside the main pipe is pressed by the drainage flowing inside the main pipe, and moves in various directions such as the direction in which the drainage flows and the direction based on the shape of the tubular body. Since the displacement of the tubular body due to such pressing lowers the efficiency of heat transfer, and thus the efficiency of energy reuse, in the above-mentioned technique, the position of each tubular body is displaced inside the main pipe. Technology that suppresses this is desired.
An object of the present invention is to provide a tubular body supporting unit capable of suppressing displacement of the tubular body inside the main pipe.
上記課題を解決するための管状体支持ユニットは、本管の内部に位置する複数の管状体を前記本管の内部で支持する管状体支持ユニットであって、前記本管を流れる媒体と熱交換を行う他の媒体を流すための前記複数の管状体の各々の延在方向を揃える管状体支持ユニットである。前記複数の管状体は、複数の管状体から構成される第1管状体群と、前記第1管状体群とは異なる複数の管状体から構成される第2管状体群とを含み、前記管状体支持ユニットは、前記第2管状体群を支持する第2支持体と、前記第1管状体群および前記第2管状体群の一部を支持する第1支持体とを備える。 A tubular body support unit for solving the above-mentioned problems is a tubular body support unit that supports a plurality of tubular bodies located inside a main pipe inside the main pipe, and heat exchange with a medium flowing through the main pipe. Is a tubular body support unit for aligning the extending directions of the plurality of tubular bodies for flowing another medium. The plurality of tubular bodies include a first tubular body group composed of a plurality of tubular bodies and a second tubular body group composed of a plurality of tubular bodies different from the first tubular body group, and the tubular body The body support unit includes a second support body that supports the second tubular body group, and a first support body that supports a portion of the first tubular body group and the second tubular body group.
上記管状体支持ユニットによれば、第1管状体群と第2管状体群とは、本管の内部を流れる媒体から別々に押圧を受ける。この際、第1管状体群が受ける力は、第1支持体を通じて第2管状体群に分散し、また、第2管状体群が受ける力は、第1支持体を通じて第1管状体群に分散する。また、第1管状体群が受ける力の方向と、第2管状体群が受ける力の方向とは、完全には一致し難く、互いに相殺されることもある。結果として、第1管状体群が受ける力によって第1管状体群の位置がずれること、および、第2管状体群が受ける力によって第2管状体群の位置がずれることを抑えることが可能となる。 According to the tubular body support unit, the first tubular body group and the second tubular body group are separately pressed from the medium flowing inside the main pipe. At this time, the force received by the first tubular body group is dispersed through the first support body to the second tubular body group, and the force received by the second tubular body group is distributed through the first support body to the first tubular body group. Spread. Further, the direction of the force received by the first tubular body group and the direction of the force received by the second tubular body group are difficult to completely coincide with each other, and may cancel each other out. As a result, it is possible to suppress the displacement of the position of the first tubular body group due to the force applied to the first tubular body group and the displacement of the position of the second tubular body group due to the force applied to the second tubular body group. Become.
上記管状体支持ユニットにおいて、前記管状体支持ユニットは、前記本管の内面における窪みに嵌まる嵌合部を備えてもよい。
上記管状体支持ユニットによれば、管状体支持ユニットが有する嵌合部が本管の内面における窪みに嵌まることによって、管状体支持ユニットの本管に対する位置ずれが抑えられる。また、上述したように、第1支持体と第2支持体との協働によってこれらの位置ずれが抑えられているため、管状体支持ユニットの位置ずれを抑えるために嵌合部が受ける負荷も軽減することが可能でもある。
In the tubular body support unit, the tubular body support unit may include a fitting portion that fits into a recess on the inner surface of the main pipe.
According to the tubular body support unit described above, the fitting portion of the tubular body support unit fits into the recess on the inner surface of the main pipe, so that the displacement of the tubular body support unit with respect to the main pipe is suppressed. Further, as described above, since the positional displacement between the first support body and the second support body is suppressed by the cooperation between the first support body and the second support body, the load applied to the fitting portion in order to suppress the positional displacement of the tubular body support unit is also reduced. It can also be mitigated.
上記管状体支持ユニットにおいて、前記第2管状体群は、複数の管状体のなかで前記第1管状体群と隣り合う管状体である境界管状体を含み、前記第1支持体は、前記第1管状体群と前記境界管状体とを支持してもよい。 In the tubular body support unit, the second tubular body group includes a boundary tubular body that is a tubular body adjacent to the first tubular body group among a plurality of tubular bodies, and the first support body is the first tubular body. One tubular body group and the boundary tubular body may be supported.
上記管状体支持ユニットによれば、第1支持体に支持される第1管状体群は、一纏まりの管状体として変位しやすく、また、第2支持体に支持される第2管状体群も、一纏まりの管状体として変位しやすい。この際、互いに隣り合う管状体の組みのなかでも、管状体間での変位が大きい組みは、第1支持体に支持される第1管状体群と、第2支持体に支持される第2管状体群とを跨ぐ組みである。上記構成によれば、第1支持体と第2支持体との両方が、これらに共通する境界管状体を支持するため、第1管状体群と第2管状体群とを跨ぐ組みでの変位を好適に抑えることが可能でもある。 According to the tubular body support unit, the first tubular body group supported by the first support body is easily displaced as a group of tubular bodies, and the second tubular body group supported by the second support body is also formed. , It is easy to displace as a group of tubular bodies. At this time, among the sets of tubular bodies adjacent to each other, the set having a large displacement between the tubular bodies is the first tubular body group supported by the first support body and the second tubular body supported by the second support body. It is a set that straddles the tubular body group. According to the above configuration, both the first support body and the second support body support the boundary tubular body common to them, so that the displacement in the group straddling the first tubular body group and the second tubular body group is large. It is also possible to suppress appropriately.
上記管状体支持ユニットにおいて、前記管状体の延在方向において、前記第1支持体の位置と前記第2支持体の位置とは互いに異なってもよい。
上記管状体支持ユニットによれば、第1支持体の位置と、第2支持体の位置とが、管状体の延在方向で互いに異なるため、第1支持体と第2支持体とに共通する管状体をこれらによって支持することが容易となる。
In the tubular body support unit, the position of the first support and the position of the second support may be different from each other in the extending direction of the tubular body.
According to the tubular body support unit, since the position of the first support body and the position of the second support body are different from each other in the extending direction of the tubular body, they are common to the first support body and the second support body. These facilitate the support of the tubular body.
上記管状体支持ユニットにおいて、前記第1支持体は、前記管状体を1つずつ支持するための複数の支持部を備え、前記第2支持体は、前記管状体を1つずつ支持するための複数の支持部を備え、前記第1支持体が備える支持部の数と、前記第2支持体が備える支持部の数とは互いに等しくてもよい。
上記管状体支持ユニットによれば、第1支持体と第2支持体とに互いに同じ構造を採用することが可能にもなる。
In the tubular body support unit, the first support body includes a plurality of support portions for supporting the tubular body one by one, and the second support body for supporting the tubular body one by one. The number of support portions provided with a plurality of support portions and provided with the first support body may be equal to the number of support portions provided with the second support body.
According to the tubular body support unit, the same structure can be adopted for the first support body and the second support body.
本発明によれば、本管の内部における管状体の位置のずれを抑えることが可能となる。 According to the present invention, it is possible to suppress the displacement of the position of the tubular body inside the main pipe.
一実施の形態における管状体支持ユニットを図1および図2を参照して説明する。
図1が示すように、本管10は、円管状を有する第1本管10Aと、円管状を有する第2本管10Bとから構成されている。第2本管10Bの延在方向における端部である第2端部10B1は、第1本管10Aに向けて拡径されており、第1本管10Aの延在方向における端部である第1端部10A1は、第2本管10Bの第2端部10B1に差し込まれている。第1端部10A1と第2端部10B1との間には、本管の延在方向に空く間隙10Sが、本管10の周方向におけるほぼ全体に形成されている。
A tubular body supporting unit in one embodiment will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the main pipe 10 is composed of a first main pipe 10A having a circular tubular shape and a second main pipe 10B having a circular tubular shape. The second end portion 10B1 which is an end portion in the extending direction of the second main pipe 10B is expanded in diameter toward the first main pipe 10A, and is the end portion in the extending direction of the first main pipe 10A. The one end 10A1 is inserted into the second end 10B1 of the second main pipe 10B. Between the first end portion 10A1 and the second end portion 10B1, a gap 10S that is open in the extending direction of the main pipe is formed almost entirely in the circumferential direction of the main pipe 10.
第1本管10Aと第2本管10Bとの間隙10Sには、支持体保持具11が嵌め込まれている。第1端部10A1の端面と、第2端部10B1の段差面との間隙10Sは、本管10の内面における窪みであり、本管10における周方向のほぼ全体に形成されている。支持体保持具11は、本管10の周方向に沿う環状体であり、本管10の内周面における窪みである間隙10Sに嵌まる嵌合部11Aを備えている。本管10の間隙10Sにこの嵌合部11Aが嵌まることによって、本管10の延在方向に沿う変位が、支持体保持具11において抑えられる。 The support holder 11 is fitted in the gap 10S between the first main pipe 10A and the second main pipe 10B. The gap 10S between the end surface of the first end portion 10A1 and the step surface of the second end portion 10B1 is a dent on the inner surface of the main pipe 10, and is formed almost entirely in the circumferential direction of the main pipe 10. The support holder 11 is an annular body that extends along the circumferential direction of the main pipe 10, and includes a fitting portion 11A that fits into a gap 10S that is a recess on the inner peripheral surface of the main pipe 10. By fitting the fitting portion 11A into the gap 10S of the main pipe 10, the displacement along the extending direction of the main pipe 10 is suppressed in the support holder 11.
本管10の内部には、本管10の延在方向に沿って延びる複数の管状体12が、互いに平行となるように位置する。互いに隣り合う管状体12において、一方の管状体12における先端部は、他方の管状体12における先端部と、連結部材13によって連結されている。また、互いに隣り合う管状体12において、一方の管状体12における基端部は、他方の管状体12における基端部と、連結部材13によって連結されている。各連結部材13は、それが連結される対象を互いに連通させる曲げ配管である。このように、互いに隣り合う管状体12が連結部材13に連結されることによって、複数の管状体12から構成される管状体群が媒体の流れる一本の流路として機能する。 Inside the main pipe 10, a plurality of tubular bodies 12 extending along the extending direction of the main pipe 10 are positioned so as to be parallel to each other. In the tubular bodies 12 adjacent to each other, the distal end portion of one tubular body 12 is connected to the distal end portion of the other tubular body 12 by a connecting member 13. Further, in the tubular bodies 12 adjacent to each other, the base end portion of one tubular body 12 is connected to the base end portion of the other tubular body 12 by the connecting member 13. Each connecting member 13 is a bent pipe that connects the objects to which it is connected to each other. In this way, the tubular bodies 12 adjacent to each other are connected to the connecting member 13, so that the tubular body group composed of the plurality of tubular bodies 12 functions as a single channel through which the medium flows.
各管状体12の並ぶ方向は、管状体12の配列方向Dである。全ての管状体のなかで配列方向Dの一端に位置する管状体12の基端部は、本管10の外側に延びる導入通路14に接続されている。全ての管状体12のなかで配列方向Dの他端に位置する管状体12の先端部は、本管10の外側に位置する導出ポンプPに接続されている。導入通路14は、それが接続された管状体12に媒体を導入する。導出ポンプPは、それが接続された管状体12から媒体を導出する。そして、導入通路14が導入された媒体は、一本の通路として機能する管状体群を通り、この間、本管10を流れる媒体から熱量を得て、導出ポンプPによって導出される。 The direction in which the tubular bodies 12 are arranged is the arrangement direction D of the tubular bodies 12. Of all the tubular bodies, the proximal end portion of the tubular body 12 located at one end in the arrangement direction D is connected to the introduction passage 14 extending to the outside of the main pipe 10. Of all the tubular bodies 12, the distal end portion of the tubular body 12 located at the other end in the arrangement direction D is connected to the lead-out pump P located outside the main pipe 10. The introduction passage 14 introduces the medium into the tubular body 12 to which it is connected. The discharge pump P discharges the medium from the tubular body 12 to which it is connected. Then, the medium introduced into the introduction passage 14 passes through the tubular body group functioning as one passage, and during this time, the amount of heat is obtained from the medium flowing through the main pipe 10 and is led out by the lead-out pump P.
本管10の内部に位置する複数の管状体12は、本管10の内部に位置する複数の支持体20によって支持されている。複数の支持体20は、支持体20と支持体保持具11との間の締結構造や嵌合構造を介して、支持体保持具11に位置決めされている。管状体支持ユニットは、これら複数の支持体20と上述した支持体保持具11とから構成されている。 The plurality of tubular bodies 12 located inside the main pipe 10 are supported by the plurality of support bodies 20 located inside the main pipe 10. The plurality of supports 20 are positioned on the support holder 11 via a fastening structure or a fitting structure between the support 20 and the support holder 11. The tubular body support unit is composed of the plurality of supports 20 and the support holder 11 described above.
以下、各支持体20と、それが支持する管状体12の位置との関係を、図2を参照して説明する。なお、図2においては、各支持体20と、それが支持する管状体12の位置との関係を説明する便宜上、互いに隣り合う管状体12の間隙を誇張して説明すると共に、また、互いに隣り合う管状体12における間隙の差異の大きさを変えて摸式的に図示する。 Hereinafter, the relationship between each support 20 and the position of the tubular body 12 supported by each support 20 will be described with reference to FIG. Note that, in FIG. 2, for the sake of convenience of explaining the relationship between each support body 20 and the position of the tubular body 12 supported by the support body 20, the gap between the tubular bodies 12 adjacent to each other is exaggerated in the description and is also adjacent to each other. The magnitude | size of the difference of the space | interval in the tubular body 12 which fits is changed, and is shown in a model.
図2が示すように、複数の管状体12は、複数の第1管状体12Aから構成される第1管状体群GAと、複数の第2管状体12Bから構成される第2管状体群GBと、複数の第3管状体12Cから構成される第3管状体群GCとから構成されている。第1管状体群GA、第2管状体群GB、第3管状体群GCの各々は、管状体12の配列方向Dに連続する管状体12の集合である。 As shown in FIG. 2, the plurality of tubular bodies 12 includes a first tubular body group GA including a plurality of first tubular bodies 12A and a second tubular body group GB including a plurality of second tubular bodies 12B. And a third tubular body group GC including a plurality of third tubular bodies 12C. Each of the first tubular body group GA, the second tubular body group GB, and the third tubular body group GC is a set of tubular bodies 12 continuous in the arrangement direction D of the tubular bodies 12.
複数の支持体20は、第1管状体群GAを支持する第1支持体20Aと、第2管状体群GBを支持する第2支持体20Bと、第3管状体群GCを支持する第3支持体20Cとから構成されている。第2管状体群GBは、複数の管状体12のなかで第1管状体群GAと隣り合う第2管状体12Bである境界管状体12BA(図2においてドットを付した管状体12)を含む。第3管状体群GCは、複数の管状体12のなかで第2管状体群GBと隣り合う第3管状体12Cである境界管状体12CB(図2においてドットを付した管状体12)を含む。 The plurality of supports 20 include a first support 20A that supports the first tubular body group GA, a second support 20B that supports the second tubular body group GB, and a third support 20B that supports the third tubular body group GC. It is composed of a support 20C. The second tubular body group GB includes a boundary tubular body 12BA (a tubular body 12 with dots in FIG. 2) which is a second tubular body 12B adjacent to the first tubular body group GA among the plurality of tubular bodies 12. . The third tubular body group GC includes a boundary tubular body 12CB (dotted tubular body 12 in FIG. 2) which is a third tubular body 12C adjacent to the second tubular body group GB among the plurality of tubular bodies 12. .
第1支持体20Aは、第1管状体群GAの他に、境界管状体12BAを支持し、また、第2支持体20Bは、第2管状体群GBの他に、境界管状体12CBを支持する。言い換えれば、境界管状体12BAは、第1支持体20Aと第2支持体20Bとに支持され、境界管状体12CBは、第2支持体20Bと第3支持体20Cとに支持される。 The first support 20A supports the boundary tubular body 12BA in addition to the first tubular body group GA, and the second support 20B supports the boundary tubular body 12CB in addition to the second tubular body group GB. To do. In other words, the boundary tubular body 12BA is supported by the first support body 20A and the second support body 20B, and the boundary tubular body 12CB is supported by the second support body 20B and the third support body 20C.
ここで、第1管状体群GAと第2管状体群GBとは、本管10の内部を流れる媒体から別々に押圧を受ける。第1管状体群GAが受ける力は、第1支持体20Aを通じて、第2管状体群GBに分散し、また、第2管状体群GBが受ける力は、第1支持体20Aを通じて、第1管状体群GAに分散する。この際、第1管状体群GAが受ける力の方向と、第2管状体群GBが受ける力の方向とは、完全には一致し難く、互いに相殺されることもある。結果として、第1管状体群GAが受ける力によって第1管状体群GAの位置がずれること、および、第2管状体群GBが受ける力によって第2管状体群GBの位置がずれることを抑えることが可能となる。 Here, the first tubular body group GA and the second tubular body group GB are separately pressed by the medium flowing inside the main pipe 10. The force received by the first tubular body group GA is dispersed to the second tubular body group GB through the first support body 20A, and the force received by the second tubular body group GB is transferred through the first support body 20A as the first force. Disperse in the tubular body group GA. At this time, the direction of the force received by the first tubular body group GA and the direction of the force received by the second tubular body group GB are difficult to completely coincide with each other and may cancel each other out. As a result, it is possible to prevent the position of the first tubular body group GA from being displaced due to the force applied to the first tubular body group GA, and to prevent the position of the second tubular body group GB from being displaced due to the force received by the second tubular body group GB. It becomes possible.
同様に、第2管状体群GBと第3管状体群GCとは、本管10の内部を流れる媒体から別々に押圧を受ける。第2管状体群GBが受ける力は、第2支持体20Bを通じて、第3管状体群GCに分散し、また、第3管状体群GCが受ける力は、第2支持体20Bを通じて、第2管状体群GBに分散する。ここでも、第2管状体群GBが受ける力の方向と、第3管状体群GCが受ける力の方向とは、完全には一致し難く、互いに相殺されることもある。結果として、第2管状体群GBが受ける力によって第2管状体群GBの位置がずれること、および、第3管状体群GCが受ける力によって第3管状体群GCの位置がずれることを抑えることが可能となる。 Similarly, the second tubular body group GB and the third tubular body group GC are separately pressed from the medium flowing inside the main pipe 10. The force received by the second tubular body group GB is distributed to the third tubular body group GC through the second support body 20B, and the force received by the third tubular body group GC is transmitted through the second support body 20B to the second support body 20B. It is dispersed in the tubular body group GB. Also here, the direction of the force received by the second tubular body group GB and the direction of the force received by the third tubular body group GC are difficult to completely match, and may cancel each other out. As a result, it is possible to prevent the position of the second tubular body group GB from being displaced due to the force received by the second tubular body group GB and the position of the third tubular body group GC from being displaced due to the force received by the third tubular body group GC. It becomes possible.
また、第1支持体20Aに支持される第1管状体群GAは、一纏まりの管状体12として変位しやすい。また、第2支持体20Bに支持される第2管状体群GBも、一纏まりの管状体12として変位しやすい。また、第3支持体20Cに支持される第3管状体群GCも、一纏まりの管状体12として変位しやすい。そのため、互いに隣り合う2つの管状体12の組みのなかでも、管状体12の間での相対的な変位が大きい組みは、第1管状体群GAと第2管状体群GBとを跨ぐ組みであり、第2管状体群GBと第3管状体群GCとを跨ぐ組みである。この点、第1管状体群GAと第2管状体群GBとを跨ぐ組みは、第1支持体20Aに支持され、また、第2管状体群GBと第3管状体群GCとを跨ぐ組みは、第2支持体20Bに支持される。それゆえに、第1管状体群GAと第2管状体群GBとを跨ぐ組み内での相対的な変位、および、第2管状体群GBと第3管状体群GCとを跨ぐ組み内での相対的な変位を、好適に抑えることが可能ともなる。 Further, the first tubular body group GA supported by the first support body 20A is easily displaced as a group of tubular bodies 12. Further, the second tubular body group GB supported by the second support body 20B is also easily displaced as a group of tubular bodies 12. In addition, the third tubular body group GC supported by the third support body 20C is also easily displaced as a group of tubular bodies 12. Therefore, among the sets of two tubular bodies 12 that are adjacent to each other, the set in which the relative displacement between the tubular bodies 12 is large is the set that straddles the first tubular body group GA and the second tubular body group GB. Yes, it is a set that straddles the second tubular body group GB and the third tubular body group GC. In this respect, a set that straddles the first tubular body group GA and the second tubular body group GB is supported by the first support body 20A, and a straddle that straddles the second tubular body group GB and the third tubular body group GC. Are supported by the second support 20B. Therefore, the relative displacement in the set straddling the first tubular body group GA and the second tubular body group GB, and the relative displacement in the set straddling the second tubular body group GB and the third tubular body group GC It also becomes possible to suitably suppress the relative displacement.
なお、各支持体20において管状体12を1つずつ支持するための支持部が有する構造は、例えば、管状体12が嵌め込まれる嵌合溝であってもよいし、管状体12が載置される隙間溝であってもよい。また、管状体12を1つずつ支持するための支持部が有する構造は、管状体12が差し込まれる差込孔であってもよいし、支持体20の本体に管状体12を締結する構造であってもよい。 In addition, the structure which the support part for supporting the tubular body 12 one by one in each support body 20 may be, for example, a fitting groove into which the tubular body 12 is fitted, or in which the tubular body 12 is placed. It may be a gap groove. Further, the structure of the support portion for supporting the tubular bodies 12 one by one may be an insertion hole into which the tubular bodies 12 are inserted, or a structure in which the tubular bodies 12 are fastened to the main body of the support body 20. It may be.
境界管状体12BAの延在方向において、第1支持体20Aの位置と、第2支持体20Bの位置とは互いに異なる。そのため、第1支持体20Aと第2支持体20Bとの物理的な干渉が抑えられ、第1支持体20Aと第2支持体20Bとに共通する境界管状体12BAを、これらによって支持することが容易となる。また、境界管状体12BAの延在方向において、第2支持体20Bの位置と、第3支持体20Cの位置とが、互いに異なる。そのため、第2支持体20Bと第3支持体20Cとの物理的な干渉が抑えられ、第2支持体20Bと第3支持体20Cとに共通する境界管状体12CBを、これらによって支持することが容易ともなる。 The position of the first support 20A and the position of the second support 20B are different from each other in the extending direction of the boundary tubular body 12BA. Therefore, physical interference between the first support body 20A and the second support body 20B is suppressed, and the boundary tubular body 12BA common to the first support body 20A and the second support body 20B can be supported by these. It will be easy. Further, in the extending direction of the boundary tubular body 12BA, the position of the second support 20B and the position of the third support 20C are different from each other. Therefore, physical interference between the second support body 20B and the third support body 20C is suppressed, and the boundary tubular body 12CB common to the second support body 20B and the third support body 20C can be supported by these. It will also be easy.

(2)支持体保持具11の嵌合部11Aが本管10の内面における窪みに嵌まることによって、管状体支持ユニットの本管10に対する位置ずれが抑えられるため、各管状体12における位置のずれを、より高い精度で抑えられる。
As described above, according to the above embodiment, the effects listed below can be obtained.
(1) It is possible to prevent the tubular body groups GA, GB, and GC from being displaced by being pressed by the medium.
(2) Since the fitting portion 11A of the support body holder 11 is fitted into the recess in the inner surface of the main pipe 10, the positional displacement of the tubular body support unit with respect to the main pipe 10 is suppressed, so that the position of each tubular body 12 can be adjusted. The deviation can be suppressed with higher accuracy.

なお、上記実施形態は、以下のように変更して実施することができる。
[支持体]
・管状体支持ユニットが備える複数の支持体20は、互いに異なる大きさを有してもよい。例えば、図3が示すように、管状体12の配列方向Dにおいて、第3支持体20Cは、第2支持体20Bや第1支持体20Aよりも短くてもよい。この際、管状体12の配列方向Dにおいて第3支持体20Cの有する長さは、第3管状体群GCの有する長さと略等しいことが好ましい。こうした第3支持体20Cの長さであれば、本管10を流れる媒体の流れが、第3支持体20Cによって阻害されることが抑えられる。
The above embodiment can be modified and implemented as follows.
[Support]
The plurality of supports 20 included in the tubular body support unit may have different sizes. For example, as shown in FIG. 3, in the arrangement direction D of the tubular bodies 12, the third support body 20C may be shorter than the second support body 20B and the first support body 20A. At this time, the length of the third support body 20C in the arrangement direction D of the tubular bodies 12 is preferably substantially equal to the length of the third tubular body group GC. With such a length of the third support 20C, it is possible to prevent the flow of the medium flowing through the main pipe 10 from being obstructed by the third support 20C.
・また、図3が示すように、管状体12の配列方向Dにおいて第2支持体20Bの有する長さは、第2支持体20Bの端部が第1管状体群GAと第3管状体群GCとの両方に到達する大きさであってもよい。この際、第1管状体群GAは、第1管状体群GAのなかで第2管状体群GBと隣り合う管状体12である境界管状体12AB(図3においてドットを付した管状体12)を含む。上述した第2支持体20Bの長さであれば、境界管状体12AB,12BAの各々が、第1支持体20Aと第2支持体20Bとの両方に支持される。それゆえに、各管状体群GA,GBが媒体から押圧を受けることによって各々の位置がずれることを、さらに抑えることが可能となる。 Further, as shown in FIG. 3, the length of the second support 20B in the arrangement direction D of the tubular bodies 12 is such that the end of the second support 20B has a first tubular body group GA and a third tubular body group. It may be of a size that reaches both the GC and the GC. At this time, the first tubular body group GA is the boundary tubular body 12AB (the tubular body 12 with dots in FIG. 3) which is the tubular body 12 adjacent to the second tubular body group GB in the first tubular body group GA. including. Each of the boundary tubular bodies 12AB and 12BA is supported by both the first support body 20A and the second support body 20B as long as the length of the second support body 20B described above is satisfied. Therefore, it is possible to further suppress the displacement of each tubular body group GA, GB from being pressed by the medium.
・支持体20の位置は、本管10の内面と管状体12との間に限らず、管状体12に対して本管10の中心側であってもよい。この際、支持体20において管状体12を1つずつ支持するための支持部が有する構造は、例えば、管状体12が嵌め込まれる嵌合溝である。 The position of the support body 20 is not limited to the position between the inner surface of the main pipe 10 and the tubular body 12, and may be the center side of the main pipe 10 with respect to the tubular body 12. At this time, the structure of the support portion for supporting the tubular bodies 12 one by one in the support body 20 is, for example, a fitting groove into which the tubular body 12 is fitted.
また、図4が示すように、本管10の内面と管状体12との間に位置する第1支持体20Aと、管状体12に対して本管10の中心側に位置する第2支持体20Bとが、本管10の中心から見て重なるように位置し、1つの境界管状体12BAが、これら第1支持体20Aと第2支持体20Bとに挟まれてもよい。同様に、本管10の内面と管状体12との間に位置する第3支持体20Cと、管状体12に対して本管10の中心側に位置する第2支持体20Bとが、本管10の中心から見て重なるように位置し、1つの境界管状体12CBが、これら第3支持体20Cと第2支持体20Bとに挟まれてもよい。こうした支持体20の配置によれば、本管10の内面から本管10の中心に向けた方向、および、本管10の中心から本管10の内面に向けた方向の両方で、管状体12の変位が抑えられる。 Further, as shown in FIG. 4, a first support body 20A located between the inner surface of the main pipe 10 and the tubular body 12, and a second support body located on the center side of the main pipe 10 with respect to the tubular body 12. 20B may be positioned so as to overlap with each other when viewed from the center of the main pipe 10, and one boundary tubular body 12BA may be sandwiched between the first support body 20A and the second support body 20B. Similarly, a third support body 20C located between the inner surface of the main pipe 10 and the tubular body 12 and a second support body 20B located closer to the center of the main pipe 10 with respect to the tubular body 12 are the main pipes. One boundary tubular body 12CB, which is positioned so as to overlap with each other when viewed from the center of 10, may be sandwiched between the third support body 20C and the second support body 20B. With such an arrangement of the support body 20, the tubular body 12 is provided both in the direction from the inner surface of the main pipe 10 to the center of the main pipe 10 and in the direction from the center of the main pipe 10 to the inner surface of the main pipe 10. Displacement is suppressed.
・管状体支持ユニットの有する支持体20の数量は、2つであってもよいし、4つ以上であってもよい。支持体20の数量が4つ以上であるとき、各支持体20の配置は、例えば、図5が示すように、本管10の延在方向における支持体20による段差を他の支持体20が埋めるように、支持体20が敷き詰められることが好ましい。また、管状体12の配列方向Dにおいて支持体20が敷き詰められることが好ましい。こうした支持体20の配置によれば、互いに隣り合う支持体20の間隙に、本管10を流れる異物が入り込むことが抑えられる。 The number of supports 20 included in the tubular body support unit may be two, or may be four or more. When the number of the support bodies 20 is four or more, the arrangement of each support body 20 is such that, for example, as shown in FIG. It is preferable that the support 20 is spread so as to be filled. Further, it is preferable that the supports 20 be spread in the arrangement direction D of the tubular bodies 12. With such an arrangement of the supports 20, it is possible to prevent foreign matter flowing in the main pipe 10 from entering the gap between the supports 20 adjacent to each other.
[支持体保持具]
・図6が示すように、支持体保持具11は、本管10の内面に向けて支持体保持具11の保持具本体11Tを押圧するための押圧構造を備えてもよい。例えば、円環状を有する保持具本体11Tは、半円環状を有する第1保持具本体111と、半円環状を有する第2保持具本体112とから構成され、第1保持具本体111の端部と第2保持具本体112の端部との間隙には、その間隙を広げる方向へ第1保持具本体111と第2保持具本体112とを押圧する押圧部材113が位置する。押圧部材113は、管状体12よりも本管10の内面近傍に位置し、それの延在方向(図中上下方向)を回転軸とした回転によって、第1保持具本体111と第2保持具本体112との間隙を広げる方向へ、第1保持具本体111と第2保持具本体112とを押圧する。こうした押圧部材113は、例えば、ボルトとナットとによって構成され、押圧部材113が間隙を拡張する力は、保持具本体11Tを本管10の内面に押圧する力に変換される。
[Support holder]
-As shown in FIG. 6, the support holder 11 may include a pressing structure for pressing the holder main body 11T of the support holder 11 toward the inner surface of the main pipe 10. For example, the holder main body 11T having an annular shape includes a first holder main body 111 having a semi-annular shape and a second holder main body 112 having a semi-annular shape, and an end portion of the first holder main body 111. A pressing member 113 that presses the first holder main body 111 and the second holder main body 112 in a direction of widening the gap is positioned in a gap between the end of the second holder main body 112 and the second holder main body 112. The pressing member 113 is located closer to the inner surface of the main pipe 10 than the tubular body 12, and is rotated about its extending direction (vertical direction in the drawing) as a rotation axis to rotate the first holding member main body 111 and the second holding member. The first holder main body 111 and the second holder main body 112 are pressed in a direction of widening the gap between the main holder 112 and the main body 112. The pressing member 113 is configured by, for example, a bolt and a nut, and the force of the pressing member 113 for expanding the gap is converted into the force for pressing the holder main body 11T against the inner surface of the main pipe 10.
そのため、支持体保持具11の位置が本管10に対してずれることを抑えることが可能ともなる。また、押圧部材113が管状体12よりも本管10の内面近傍に位置するため、こうした押圧部材113が本管10の中心近傍に位置する構成と比べて、本管10の内部を流れる媒体の流れが押圧部材113によって阻害されることを抑えることが可能でもある。 Therefore, it is possible to prevent the position of the support holder 11 from being displaced with respect to the main pipe 10. In addition, since the pressing member 113 is located closer to the inner surface of the main pipe 10 than the tubular body 12, compared with the configuration in which the pressing member 113 is located near the center of the main pipe 10, the medium flowing inside the main pipe 10 is It is also possible to prevent the flow from being obstructed by the pressing member 113.
・支持体20を本管10に固定する機能を支持体20そのものが備える構成であってもよい。例えば、管状体支持ユニットの備える嵌合部を支持体20が備え、支持体保持具11が管状体支持ユニットから割愛されてもよい。こうした支持体20の構成によれば、管状体支持ユニットを構成する部材の点数を低減することが可能ともなる。 The support 20 itself may have a function of fixing the support 20 to the main pipe 10. For example, the support body 20 may include the fitting portion included in the tubular body support unit, and the support body holder 11 may be omitted from the tubular body support unit. With such a configuration of the support body 20, it is possible to reduce the number of members constituting the tubular body support unit.
[管状体]
・第1支持体20Aと第2支持体20Bとによって支持される管状体12は、第2管状体群GBのなかで境界管状体12BA以外の他の管状体12であってもよい。また、第2支持体20Bと第3支持体20Cとによって支持される管状体12は、第3管状体群GCのなかで境界管状体12BC以外の他の管状体12であってもよい。要は、第1支持体20Aは、第1管状体群GAおよび第2管状体群GBの一部を支持する構成であればよい。また、第2支持体20Bは、第2管状体群GBおよび第3管状体群GCの一部を支持する構成であればよい。なお、第1支持体20Aと第2支持体20Bとのいずれか一方が割愛されてもよい。
[Tubular body]
The tubular body 12 supported by the first support body 20A and the second support body 20B may be a tubular body 12 other than the boundary tubular body 12BA in the second tubular body group GB. The tubular body 12 supported by the second support body 20B and the third support body 20C may be a tubular body 12 other than the boundary tubular body 12BC in the third tubular body group GC. In short, the first support body 20A may be configured to support a part of the first tubular body group GA and the second tubular body group GB. Further, the second support body 20B may be configured to support a part of the second tubular body group GB and the third tubular body group GC. Either one of the first support 20A and the second support 20B may be omitted.
・複数の管状体12は、連結部材13によって連結される構成に限らず、導入通路14および導出ポンプPに管状体12が1つずつ接続され、各管状体12が個別の配管として構成されてもよい。 The plurality of tubular bodies 12 are not limited to being connected by the connecting member 13, but one tubular body 12 is connected to each of the introduction passage 14 and the discharge pump P, and each tubular body 12 is configured as an individual pipe. Good.
・管状体12の有する形状は、直管状に限らず、本管10の延在方向に延在する波線状であってもよいし、本管10の内周面に沿って延在するスパイラル状であってもよい。また、複数の管状体12は、1つの管体のなかの一部分であってもよく、要は、複数の管状体は、本管を流れる媒体と熱交換を行う他の媒体を流すための管体であって、複数の管状体の各々の延在方向を管状体支持ユニットが揃える構成であればよい。 The shape of the tubular body 12 is not limited to a straight tube, and may be a wavy line extending in the extending direction of the main tube 10 or a spiral shape extending along the inner peripheral surface of the main tube 10. May be Further, the plurality of tubular bodies 12 may be a part of one tubular body, and in short, the plurality of tubular bodies 12 are tubes for flowing another medium that exchanges heat with a medium flowing through the main pipe. The tubular body support unit may be a body, and the tubular body support units are aligned in the extending direction of each of the plurality of tubular bodies.
