Description

Technical Field

[0001] This application relates to the technical field of heat exchange devices, and in particular to a heat exchange structure. Background Technology

[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures.

[0003] refer to Figure 1 A heat exchange mechanism 2 includes a pool body 81, with an inlet pipe 82 and an outlet pipe 83 connected to the pool body 81. A cooling coil 84 is placed inside the pool body 81. The inlet pipe introduces the liquid to be heated into the pool body 81, and then a refrigerant is introduced into the cooling coil 84. When the refrigerant moves within the cooling coil 84, the temperature of the liquid near the cooling coil 84 in the pool body 81 drops faster, and then the liquid near the cooling coil 84 exchanges heat with the liquid away from the cooling coil 84.

[0004] Because the liquid near the cooling coil 84 will cool down faster after exchanging heat with the cooling coil 84, the heat transfer coefficient of the cooling coil 84 to the liquid whose temperature has dropped will be relatively low. The cooling coil will only improve its heat transfer coefficient when the liquid far away from the cooling coil 84 transfers heat to the liquid near the cooling coil 84. Since the pool body 81 has a relatively large space, the cooling time of the liquid in the pool body 81 will be longer, resulting in lower efficiency. Summary of the Invention

[0005] To improve efficiency, this application provides a heat exchange structure.

[0006] This application provides a heat exchange structure that adopts the following technical solution:

[0007] A heat exchange structure includes a barrel, a refrigerant inlet pipe, a refrigerant outlet pipe, and a heat exchange mechanism. A heat exchange cavity is formed within the barrel. The heat exchange mechanism is located within the heat exchange cavity and divides the heat exchange cavity from bottom to top into a first flow cavity, a refrigerant spiral channel, and a second flow cavity. The refrigerant spiral channel is formed by the heat exchange mechanism. The refrigerant inlet pipe is disposed on the barrel and communicates with the first flow cavity, and the refrigerant outlet pipe is disposed on the barrel and communicates with the second flow cavity.

[0008] By adopting the above technical solution, the liquid to be cooled enters the heat exchange mechanism, causing it to move from top to bottom within the heat exchange chamber. Then, the refrigerant enters the first flow chamber through the refrigerant inlet pipe, flows through the refrigerant spiral channel to the second flow chamber, and finally flows out through the refrigerant outlet pipe. The refrigerant moves spirally from bottom to top within the refrigerant spiral channel, while the liquid to be cooled moves from top to bottom, creating convection between the refrigerant and the liquid. This ensures that the liquid to be cooled has completely exchanged heat by the time it exits the heat exchange chamber and will not exchange heat with the subsequent liquid. Therefore, the heat exchange mechanism provided in this application can improve heat exchange efficiency.

[0009] Optionally, the heat exchange mechanism includes multiple first heat exchange components, each of which includes multiple first spiral tubes. The diameters of the multiple first spiral tubes in each first heat exchange component are the same, their centerlines coincide, and they are staggered. The diameter of the first spiral tube in an adjacent first heat exchange component is larger than that in the first heat exchange component. The multiple first spiral tubes in adjacent first heat exchange components correspond one-to-one with the multiple first spiral tubes in the first heat exchange component, and the first spiral tubes in adjacent first heat exchange components abut against each other. The multiple first spiral tubes in the first heat exchange component and the multiple first spiral tubes in adjacent first heat exchange components form a first spiral channel. All the first spiral channels in the heat exchange mechanism form a second spiral channel, which forms the refrigerant spiral channel. The first spiral tube with the smallest diameter and the first spiral tube with the largest diameter in the heat exchange mechanism both abut against the peripheral sidewall of the heat exchange chamber.

[0010] By adopting the above technical solution, the liquid to be cooled enters the first spiral tube and moves in a spiral motion from top to bottom along the tube. Because both the smallest and largest diameter first spiral tubes abut against the peripheral wall of the heat exchange chamber, the refrigerant can only move along the refrigerant spiral channel formed by multiple first spiral tubes. Since the refrigerant spiral channel is formed by multiple first spiral tubes, the refrigerant will abut against the side wall of the first spiral tube when moving in the refrigerant spiral channel. In this way, the liquid to be cooled moving in a spiral motion from top to bottom and the refrigerant moving in a spiral motion from bottom to top form an opposition, thereby cooling the liquid by the refrigerant. The multiple first spiral tubes can increase the amount of liquid entering the heat exchanger for heat exchange and cooling, thereby improving efficiency.

[0011] Optionally, the heat exchange mechanism includes a plurality of second heat exchange components, each second heat exchange component including a plurality of second spiral tubes. The plurality of second spiral tubes in each second heat exchange component have the same diameter, their centerlines coincide, and they are staggered. The diameter of the second spiral tube in an adjacent second heat exchange component is larger than the diameter of the second spiral tube in the corresponding second heat exchange component. The plurality of second spiral tubes in adjacent second heat exchange components correspond one-to-one with the plurality of second spiral tubes in the corresponding second heat exchange component, and the second spiral tubes in adjacent second heat exchange components abut against each other. Multiple second spiral tubes and multiple second spiral tubes in adjacent second heat exchange components form a third spiral channel; all the third spiral channels in the heat exchange mechanism form a fourth spiral channel; the second spiral tube with the smallest diameter in the second heat exchange component in the heat exchange mechanism abuts against the first spiral tube with the largest diameter in the first heat exchange component in the heat exchange mechanism and forms a fifth spiral channel; the second spiral channel, the fourth spiral channel, and the fifth spiral channel together form the refrigerant spiral channel; the second spiral tube with the largest diameter in the second heat exchange component in the heat exchange mechanism and the first spiral tube with the smallest diameter in the first heat exchange component in the heat exchange mechanism both abut against the peripheral sidewall of the heat exchange cavity.

[0012] By adopting the above technical solution, when the diameter of the heat exchange chamber increases, the first spiral tube with the largest diameter cannot correspond well to the first spiral tube with the smaller diameter. Therefore, multiple second spiral tubes are set outside the first spiral tube with the largest diameter. The fourth spiral channel formed by multiple second heat exchange components allows the refrigerant to pass through and exchange heat with and cool the liquid in the second spiral tube forming the fourth spiral channel. When the fifth spiral channel formed by the second spiral tube with the smallest diameter and the first spiral tube with the largest diameter are connected to the fourth spiral channel formed by multiple second spiral tubes and the second spiral channel formed by multiple first spiral tubes, the second spiral channel, the fourth spiral channel and the fifth spiral channel can be used to form a refrigerant spiral channel. In this way, when the refrigerant moves in the refrigerant spiral channel formed by multiple first spiral tubes and multiple second spiral tubes, it still moves spirally from bottom to top.

[0013] Optionally, multiple first spiral channels are arranged in parallel, and multiple third spiral channels are arranged in parallel.

[0014] By adopting the above technical solution, multiple first spiral channels are arranged in parallel, which can make the second spiral channel tend to the spiral path and reduce the phenomenon of the second spiral channel path deviation; multiple third spiral channels are arranged in parallel, which can make the fourth spiral channel tend to the spiral path and reduce the phenomenon of the fourth spiral channel path deviation.

[0015] Optionally, an extension mechanism is also included, comprising a mounting block, a main pipe, a first extension pipe, and a second extension pipe. The mounting block is disposed on the outer wall of the barrel body and has a third flow cavity. The main pipe is disposed on the mounting block and communicates with the third flow cavity. Two mounting blocks are provided, and the inlet end of the first spiral tube and the inlet end of the second spiral tube are each provided with a first extension pipe connected to one of the mounting blocks, and the first extension pipe communicates with the flow cavity on the mounting block. The outlet end of the first spiral tube and the outlet end of the second spiral tube are each provided with a second extension pipe connected to the other mounting block, and the second extension pipe communicates with the flow cavity on the mounting block.

[0016] By adopting the above technical solution, the liquid requiring heat exchange and cooling is introduced into the main pipe on one of the mounting blocks. The liquid enters the third flow chamber of the mounting block, and then enters the first spiral tube and the second spiral tube through multiple first extension tubes. The heat-cooled liquid enters the second extension tube through the multiple first spiral tubes and the multiple second spiral tubes, and then enters the third flow chamber of another mounting block, and finally flows out through the main pipe. The extension mechanism facilitates the introduction of the liquid requiring heat exchange and cooling into the multiple first spiral tubes and the multiple second spiral tubes, and also facilitates the collection of the cooled liquid.

[0017] Optionally, the mounting block is provided with an adjustment device connected to the main pipe. The adjustment device includes a fixing ring block, a connecting ring block, a first connecting block, a second connecting block, a first rotating ball, a second rotating ball, a limiting mechanism, and a sealing assembly. The mounting block has a first through hole communicating with the flow cavity, and the diameter of the first through hole is larger than the diameter of the main pipe. The fixing ring block is disposed on the mounting block, and the connecting ring block is disposed on the main pipe. The first connecting block has a first groove, and the second connecting block is slidably disposed in the first groove. The first rotating ball is fixedly disposed on the first connecting block, and the fixing ring block has a first rotation limiting groove that is rotatably connected to and limits the first rotating ball. The second rotating ball is fixedly disposed on the second connecting block, and the connecting ring block has a second rotation limiting groove that is rotatably connected to and limits the second rotating ball. The limiting mechanism limits the first rotating ball or the second rotating ball. The sealing assembly is disposed on the mounting block, and the sealing assembly and the main pipe jointly seal the first through hole.

[0018] By adopting the above technical solution, when the pipe connected to the main pipe is fixed and has a small angular deviation from the main pipe, the operator adjusts the angle of the main pipe relative to the mounting block. The connecting ring block on the main pipe will drive the second connecting block to move through the first rotating ball, causing the second connecting block to slide in the first groove. The first rotating ball will rotate in the first rotation limiting groove of the fixed ring block, and the second rotating ball will rotate in the second rotation limiting groove of the connecting ring block. After the position of the main pipe is adjusted, the limiting mechanism is used to limit the first rotating ball or the second rotating ball. In this way, the position and angle of the first connecting block and the second connecting block will be fixed, thereby fixing the position of the connecting ring block and realizing the fixation of the position of the main pipe. The sealing component can seal the first through hole after the position of the main pipe is adjusted, reducing the phenomenon of flow out through the first through hole.

[0019] Optionally, the limiting mechanism includes a first rotating block, a second rotating block, a half block, a limiting block, and a first adjusting component. The connecting ring block has an adjusting cavity communicating with the second rotating limiting groove. Both the first rotating block and the second rotating block are rotatably disposed within the adjusting cavity. Each of the first rotating block and the second rotating block has a half block. The limiting block is disposed on the half block and has an arc-shaped groove. The arc-shaped grooves on the two limiting blocks form a limiting groove, and the second rotating ball can abut against the sidewall of the limiting groove. The first adjusting component is disposed on the connecting ring block, and both the first rotating block and the second rotating block are connected to the first adjusting component.

[0020] By adopting the above technical solution, the first rotating block drives the second rotating block to rotate through the first adjusting component, and the rotation direction of the second rotating block is opposite to that of the first rotating block. This causes the half blocks on the first and second rotating blocks to move towards each other, and the two limiting blocks will move towards each other, so that the arc grooves on the two limiting blocks form limiting grooves. The second rotating ball abuts against the side wall of the limiting groove, thereby fixing the second rotating ball and reducing the phenomenon of the second rotating ball continuing to rotate.

[0021] Optionally, the second connecting block is provided with a reinforcing mechanism, which includes an adjusting block, a reinforcing block, and a second adjusting component. The adjusting block is slidably disposed on the second rotating ball, and the sidewall of the limiting groove can abut against the adjusting block. The reinforcing block is slidably disposed on the second connecting block and can abut against the sidewall of the first groove. The second adjusting component is disposed on the second connecting block, and both the adjusting block and the reinforcing block are connected to the second adjusting component.

[0022] By adopting the above technical solution, during the process of the limiting groove formed by the two limiting blocks pressing against the second rotating ball, the limiting blocks will cause the adjusting block to move, and the adjusting block will drive the reinforcing block to move through the second adjusting component; when the limiting groove formed by the limiting blocks presses against the second rotating ball, the reinforcing block presses against the side wall of the first groove, reducing the phenomenon of the second connecting block moving relative to the first connecting block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The heat exchange mechanism provided in this application can improve heat exchange efficiency;

[0025] 2. The extension mechanism facilitates the introduction of liquid requiring heat exchange and cooling into multiple first spiral tubes and multiple second spiral tubes, and also facilitates the collection of the cooled liquid. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 2-11 This application will be described in further detail.

[0039] This application discloses a heat exchange structure.

[0040] Example 1

[0041] refer to Figure 2 and Figure 3A heat exchange structure includes multiple barrels 11, each barrel 11 having a heat exchange chamber. A heat exchange mechanism 2 is installed within each heat exchange chamber, dividing the heat exchange chamber from bottom to top into a first flow chamber 111, a refrigerant spiral channel, and a second flow chamber 112 that are interconnected. A refrigerant inlet pipe 12 communicating with the first flow chamber 111 is fixedly connected to the lower end of each barrel 11, and a refrigerant outlet pipe 13 communicating with the second flow chamber 112 is fixedly connected to the upper end of each barrel 11. Each barrel 11 has a heat exchange mechanism 2 and an extension mechanism 3. A first connecting pipe 71 connects the extension mechanisms 3 of adjacent barrels 11.

[0042] A second connecting pipe 72 is provided on one side of multiple barrels 11. Multiple third connecting pipes 73 are connected to the second connecting pipes 72. The end of the third connecting pipe 73 away from the second connecting pipe 72 is connected to the refrigerant inlet pipe 12. A fourth connecting pipe 74 is provided on one side of multiple barrels 11. Multiple fifth connecting pipes 75 are connected to the fourth connecting pipe 74. The end of the fifth connecting pipe 75 away from the fourth connecting pipe 74 is connected to the refrigerant outlet pipe 13.

[0043] refer to Figure 3 , Figure 4 and Figure 5 The heat exchange chamber has an annular cross-section, and the heat exchange mechanism 2 includes multiple first heat exchange components 21 and multiple second heat exchange components 22.

[0044] Each first heat exchange component 21 includes multiple first spiral tubes 211. The multiple first spiral tubes 211 in the same first heat exchange component 21 have the same diameter and are staggered. The diameters of the first spiral tubes 211 in the multiple first heat exchange components 21 are different. The diameter of the first spiral tube 211 in adjacent first heat exchange components 21 is larger than the diameter of the first spiral tube 211 in the first heat exchange component 21. The first spiral tubes 211 in adjacent first heat exchange components 21 correspond one-to-one with the first spiral tubes 211 in the first heat exchange component 21. The centerlines of all the first spiral tubes 211 in the first heat exchange mechanism 2 coincide.

[0045] In this embodiment, there are three first heat exchange components 21, which are designated as the first, second, and third first heat exchange components 21 in ascending order of diameter of the first spiral tubes 211. Each first heat exchange component 21 contains two first spiral tubes 211, which are designated as the first and second first spiral tubes 211 in descending order. There is a certain distance between the first and second first spiral tubes 211 in the same first heat exchange component 21.

[0046] The first spiral tube 211 in the second first heat exchange assembly 21 is fitted outside the first first spiral tube 211 in the first first heat exchange assembly 21, and the first spiral tube 211 in the third first heat exchange assembly 21 is fitted outside the first spiral tube 211 in the second first heat exchange assembly 21.

[0047] The first helical tube 211 in the second heat exchange component 21 abuts against the first helical tube 211 in the first heat exchange component 21, and the second helical tube 211 in the second heat exchange component 21 abuts against the second helical tube 211 in the first heat exchange component 21. Because there is a certain distance between the two helical tubes 211 in each heat exchange component 21, the two helical tubes 211 in the first heat exchange component 21 and the two helical tubes 211 in the second heat exchange component 21 form a first helical channel 212. The first helical tube 211 in the third heat exchange component 21 abuts against the first helical tube 211 in the second heat exchange component 21, and the second helical tube 211 in the third heat exchange component 21 abuts against the second helical tube 211 in the second heat exchange component 21. The two helical tubes 211 in the third heat exchange component 21 and the two helical tubes 211 in the second heat exchange component 21 form a second helical channel 212. The first spiral channel 212 and the second spiral channel 212 are arranged in parallel, and the first spiral channel 212 and the second spiral channel are connected to form the second spiral channel 213.

[0048] refer to Figure 3 , Figure 4 and Figure 5 Each second heat exchange component 22 includes multiple second spiral tubes 221. The multiple second spiral tubes 221 in the same second heat exchange component 22 have the same diameter and are staggered. The diameters of the second spiral tubes 221 in the multiple second heat exchange components 22 are different. The diameter of the second spiral tube 221 in adjacent second heat exchange components 22 is larger than the diameter of the second spiral tube 221 in the first heat exchange mechanism 2. The second spiral tubes 221 in adjacent second heat exchange components 22 correspond one-to-one with the second spiral tubes 221 in the first heat exchange mechanism 2. The centerlines of all second spiral tubes 221 in the first heat exchange mechanism 2 coincide, and the centerline of the second spiral tube 221 coincides with the centerline of the first spiral tube 211.

[0049] In this embodiment, there are two second heat exchange components 22, designated as the first and second second heat exchange components 22 according to the diameter of the first spiral tube 211 from smallest to largest. Each first heat exchange component 21 contains three second spiral tubes 221, designated as the first, second, and third second spiral tubes 221 from top to bottom. A certain distance exists between the first and second second spiral tubes 221 within the same second heat exchange component 22, and a certain distance also exists between the third and second second spiral tubes 221. The second spiral tube 221 in the second second heat exchange component 22 is fitted over the first second spiral tube 221 in the first second heat exchange component 22.

[0050] The first second spiral tube 221 in the second second heat exchange assembly 22 abuts against the first second spiral tube 221 in the first second heat exchange assembly 22, the second second spiral tube 221 in the second second heat exchange assembly 22 abuts against the second second spiral tube 221 in the first second heat exchange assembly 22, and the third second spiral tube 221 in the third second heat exchange assembly 22 abuts against the third second spiral tube 221 in the second second heat exchange assembly 22.

[0051] The three second spiral tubes 221 in the first second heat exchange assembly 22 and the three second spiral tubes 221 in the second second heat exchange assembly 22 form a third spiral channel 222. When there are three second heat exchange assemblies 22, the three second spiral tubes 221 in the third heat exchange assembly and the three second spiral tubes 221 in the second second heat exchange assembly 22 also form a third spiral channel 222. All the third spiral channels 222 in all the second heat exchange assemblies 22 are arranged in parallel, and the third spiral channels 222 that are close to each other are connected to form a fourth spiral channel.

[0052] Any one of the second spiral tubes 221 in the first second heat exchange assembly 22 abuts against any one of the first spiral tubes 211 in the third first heat exchange assembly 21. In this way, the three adjacent second spiral tubes 221 in the first second heat exchange assembly 22 and the two first spiral tubes 211 in the third first heat exchange assembly 21 form a fifth spiral channel 23. There is a height difference between the second spiral channel 213 and the fourth spiral channel, and they are connected through the fifth spiral channel 23.

[0053] refer to Figure 3 and Figure 5In the first heat exchange assembly 21, the sidewalls of the two first spiral tubes 211 on the side away from the first spiral tube 211 in the second heat exchange assembly 21 both abut against the inner sidewall of the heat exchange chamber. Similarly, the sidewalls of the three second spiral tubes 221 in the second heat exchange assembly 22 on the side away from the second spiral tube 221 in the first heat exchange assembly 22 both abut against the outer sidewall of the heat exchange chamber. Thus, the multiple first spiral tubes 211 in the multiple first heat exchange assemblies 21 and the multiple second spiral tubes 221 in the multiple second heat exchange assemblies together form a refrigerant spiral channel.

[0054] refer to Figure 2 and Figure 3 The extension mechanism 3 includes two mounting blocks 31 fixedly connected to the barrel body 11, each mounting block 31 having a third flow cavity 311 formed thereon; each mounting block 31 has a main pipe 32 fixedly connected to the third flow cavity 311. One mounting block 31 has a plurality of first extension pipes 33 fixedly connected to the third flow cavity 311, with one end of a portion of the first extension pipes 33 away from the mounting block 31 connected to the feed end of the first spiral tube 211, and the other end of a portion of the first extension pipes 33 away from the mounting block 31 connected to the feed end of the second spiral tube 221; the other mounting block 31 has a plurality of second extension pipes 34 fixedly connected to the third flow cavity 311, with one end of a portion of the second extension pipes 34 away from the mounting block 31 connected to the discharge end of the first spiral tube 211, and the other end of a portion of the second extension pipes 34 away from the mounting block 31 connected to the discharge end of the second spiral tube 221.

[0055] One end of the first connecting pipe 71 is connected to the main pipe 32 on one of the barrels 11, and the other end is connected to the mounting block 31 on the other barrel and communicates with the third flow chamber 311. In this way, the liquid to be cooled is uniformly introduced into the first spiral pipe 211 and the second spiral pipe 221 in the two barrels 11, and the cooled liquid flows out uniformly from the first spiral pipe 211 and the second spiral pipe 221 in the two barrels 11.

[0056] The implementation principle of Embodiment 1 of this application is as follows: A mounting block 31 on one of the barrels 11, connected to a first connecting pipe 71 and correspondingly having a first extension pipe 33, is designated as the first mounting block 31. The barrel 11 connected to the first mounting block 31 is designated as the first barrel 11. Another mounting block 31 on the first barrel 11 is designated as the fourth mounting block 31. The other barrel 11 is designated as the second barrel 11. A mounting block 31 on the second barrel 11 connected to the first extension pipe 33 is designated as the second mounting block 31. A mounting block 31 connected to the second extension pipe 34 is designated as the third mounting block 31. Furthermore, a delivery pipe for transmitting the liquid requiring cooling is connected to the main pipe 32 on the first mounting block 31, and the main pipe 32 on the fourth mounting block 31 is connected to the output pipe for transmitting the cooled liquid.

[0057] The liquid to be cooled is introduced into the main pipe 32 on the first mounting block 31 through the delivery pipe. The liquid to be cooled will enter the third flow chamber 311 of the first mounting block 31, and then enter the first extension pipe 33 of the first barrel 11 and the first connecting block 43 connected to the first mounting block 31. The first connecting pipe 71 will introduce the liquid into the third flow chamber 311 of the second mounting block 31 through the main pipe 32 on the second mounting block 31, and then into the first extension pipe 33 connected to the second barrel 11. The first extension pipe 33 transfers the liquid in the third flow chamber 311 on the mounting block 31 to multiple first spiral pipes 211 and multiple second spiral pipes 221, so that the liquid to be cooled makes a spiral motion from top to bottom in the heat exchange chamber of the cylinder; the liquid that has been cooled in the first spiral pipes 211 and the second spiral pipes 221 enters the third flow chamber 311 of the third mounting block 31 and the fourth mounting block 31 through the second extension pipe 34; the liquid in the third flow chamber 311 on the third mounting block 31 enters the third flow chamber 311 of the fourth mounting block 31 through the first connecting pipe 71 and the main pipe 32; finally, the liquid in the third flow chamber 311 of the fourth mounting block 31 flows out through the output pipe.

[0058] The refrigerant enters the third connecting pipe 73 through the second connecting pipe 72, then enters the refrigerant inlet pipe 12, and then enters the first flow chamber 111 inside the two barrels 11. The refrigerant in the first flow chamber 111 enters the refrigerant spiral channel. Due to the spiral arrangement of the spiral tubes, the refrigerant spiral channel is also spiral. Moreover, the sidewall of the refrigerant spiral channel is formed by the sidewalls of the first spiral tube 211 and the second spiral tube 221. Therefore, the refrigerant moves spirally from top to bottom in the refrigerant spiral channel, and the refrigerant will resist the sidewalls of the first spiral tube 211 and the second spiral tube 221. When the refrigerant moves in the refrigerant spiral channel, it will exchange heat with the liquid in the first spiral tube 211 and the second spiral tube 221, thereby achieving the cooling of the liquid. After heat exchange, the refrigerant in the refrigerant spiral channel enters the second flow chamber 112, then enters the fifth connecting pipe 75 through the refrigerant outlet pipe 13, and finally enters the fourth connecting pipe 74.

[0059] Example 2

[0060] refer to Figure 6 The difference from Embodiment 1 is that the mounting block 31 is provided with an adjustment device 4 connected to the main pipe 32.

A third rotating shaft 557 is rotatably connected to the connecting ring block 42 between the second rotating shaft 555 and the first rotating shaft 552. A first bevel gear 558 is keyed to the third rotating shaft 557. A second bevel gear 559 that meshes with the first bevel gear 558 is keyed to one end of the first rotating shaft 552 near the third rotating shaft 557. A third bevel gear 5510 that meshes with the first bevel gear 558 is keyed to one end of the second rotating shaft 555 near the third rotating shaft 557.

[0065] When the main pipe 32 is connected to the first connecting pipe 71 or the conveying pipe, it is connected by a flange. The angle of the main pipe 32 relative to the mounting block 31 is adjusted so that the main pipe 32 can be aligned with the first connecting pipe 71, that is, the flange on the main pipe 32 is aligned with the flange on the first connecting pipe 71; or the flange on the main pipe 32 abuts against the flange on the conveying pipe. When adjusting the main pipe 32, the main pipe 32 drives the connecting ring block 42 to rotate. The second rotating ball 46 on the connecting ring block 42 drives the second connecting block 44 to rotate. The second connecting block 44 drives the first connecting block 43 to rotate. The first rotating ball 45 on the first connecting block 43 rotates relative to the fixed ring block 41. After the position of the main pipe 32 is determined, the operator rotates the lever 56. The lever 56 drives the first rotating block 51 to rotate. The first gear ring 551 on the first rotating block 51 drives the first gear 553 to rotate. The first gear 553 drives the first rotating shaft 552 to rotate. The second bevel gear 559 on the first rotating shaft 552 drives the first bevel gear 558 to rotate. The first bevel gear 558 drives the third bevel gear 5510 to rotate. The third bevel gear 5510 drives the second rotating shaft 555 to rotate. The second gear 556 on the second rotating shaft 555 drives the second gear 556 to rotate. The second gear 556 drives the second gear ring 554 to rotate, and the second gear ring 554 drives the second rotating block 52 to rotate. The second rotating block 52 and the first rotating block 51 rotate in opposite directions, causing the half block 53 on the first rotating block 51 and the half block 53 on the second rotating block 52 to move towards each other. In this way, the limiting block 54 on the first rotating block 51 and the limiting block 54 on the second rotating block 52 will move towards each other, so that the arc groove 541 on the two limiting blocks 54 forms a limiting groove, and both limiting blocks 54 abut against the second rotating ball 46, reducing the phenomenon of the second rotating ball 46 rotating. When both limiting blocks 54 abut against the second rotating ball 46, the pusher block 56 is located at one end of the second through hole 422. Then the operator makes the locking bolt 57 pass through the third through hole 423 on the connecting ring block 42 and threadedly connect it to the threaded hole on the first rotating block 51.

[0066] refer to Figure 6 , Figure 8 and Figure 11 The second connecting block 44 has a second groove 441 that communicates with the first groove on the first connecting block 43, and the second connecting block 44 located in the first groove has a second through hole 422 that communicates with the second groove 441; the second rotating ball 46 has a first cavity 461 that communicates with the second groove 441 on the second connecting block 44, and the second rotating ball 46 has a third through hole 423 that communicates with the first cavity 461.

[0067] The second connecting block 44 is provided with a reinforcing mechanism 6, which includes an adjusting block 61 that is slidably connected to the third through hole 423 on the second rotating ball 46, and a reinforcing block 62 that is slidably connected to the second through hole 422 of the second connecting block 44. A second adjustment assembly is provided on the second connecting block 44. The second adjustment assembly includes a fourth rotating shaft 631 rotatably connected to the second connecting block 44. One end of the fourth rotating shaft 631 is located in the second groove 441 of the second connecting block 44, and the other end is located in the first cavity 461 of the second rotating ball 46. A third gear 632 is keyed to the fourth rotating shaft 631 located in the first cavity 461. A first rack 633 that meshes with the third gear 632 is integrally provided on the adjustment block 61. A fourth gear 634 is keyed to the fourth rotating shaft 631 located in the second groove 441. A second rack 635 that meshes with the fourth gear 634 is integrally provided on the reinforcing block 62. A torsion spring is sleeved on the fourth rotating shaft 631. One end of the torsion spring is connected to the fourth rotating shaft 631, and the other end is connected to the second connecting block 44.

[0068] When the second rotating ball 46 rotates within the adjustment cavity 421, one end of the third gear 632 of the adjustment block 61 can move within the adjustment cavity 421. When both the limiting block 54 on the first rotating block 51 and the limiting block 54 on the second rotating block 52 abut against the second rotating ball 46, the limiting block 54 on the first rotating block 51 or the limiting block 54 on the second rotating block 52 will push the adjustment block 61 to move. The first rack 633 on the adjustment block 61 drives the third gear 632 to rotate, the third gear 632 drives the fourth rotating shaft 631 to rotate, and the fourth gear 634 on the fourth rotating shaft 631 drives the second rack 635 to move. The second rack 635 will then drive the reinforcing block 62 to move, so that one end of the reinforcing block 62 passes through the second through hole 422 on the second connecting block 44 and abuts against the side wall of the first groove on the first connecting block 43, thereby improving the stability of the second connecting block 44 on the first connecting block 43.

[0069] refer to Figure 6 The mounting block 31 is equipped with a sealing component 47, which can be a sealant. After the position of the main pipe 32 relative to the mounting block 31 is adjusted, the sealant is applied to the main pipe 32 and seals the first through hole. Alternatively, the sealing component 47 can be an airbag ring, which is mounted on the mounting block 31, and the main pipe 32 passes through the airbag ring. The airbag ring is not inflated before the main pipe 32 is adjusted; after the main pipe 32 is adjusted, air is inflated into the airbag ring, causing the airbag ring to abut against the side wall of the main pipe 32, thus sealing the first through hole. Finally, the connection between the airbag ring and the main pipe 32, as well as the connection between the airbag ring and the mounting block 31, is sealed with sealant.
