Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compensators, in particular to a compensator that is convenient for heat dissipation. Background Art
[0002] A compensator generally refers to an expansion joint. An expansion joint is a flexible element that can effectively compensate for axial deformation. For example, the expansion joint welded to the shell of a fixed tube-sheet heat exchanger has large axial flexibility and is easy to deform. It can compensate for the thermal expansion difference between the tube and the shell due to different wall temperatures and reduce their axial load. A bellows compensator is a device used to compensate for thermal expansion and contraction, vibration and displacement in a piping system. It can be used in industries such as petroleum, chemical, electric power, pharmaceuticals, urban heating, and metallurgy.
[0003] The corrugated compensator can absorb a large amount of thermal expansion and contraction, thereby avoiding stress concentration and damage in the piping system. However, due to the long-term flow of heat medium inside, and when the temperature of part of the heat medium is too high, the general corrugated compensator itself has insufficient heat dissipation capacity, which will lead to excessive expansion and contraction and damage to the compensator. For this reason, we have proposed a compensator that is easy to dissipate heat. Utility Model Content

[0007] As a preferred technical solution of the present invention, a slot is provided on one side wall of the ear plate, and the shape of the clamping column matches the slot.
[0008] With the above technical solution, the support connection is achieved by inserting the card column into the card slot. When disassembling, the card column can be displaced out of the card slot.
[0009] As a preferred technical solution of the present invention, one side wall of the blade is fixedly connected to the outer wall of the thin rod.
[0010] Through the above technical solution, the blades are fixed on the thin rod. When there is airflow around, the blades can be blown to rotate, thereby driving the thin rod to rotate.
[0011] As a preferred technical solution of the present invention, both ends of the thin rod are rotatably connected to end plates, and compression springs are fixedly connected between the end plates and the adjacent support rods.
[0012] Through the above technical solution, the thin rod rotates on the end plate to ensure that it can rotate smoothly. At the same time, the compression spring realizes elastic connection, ensures the normal operation of the compensator, and provides buffering.
[0013] As a preferred technical solution of the present invention, the middle parts of both side walls of the arc-shaped plate are fixedly connected with splicing plates, and two adjacent splicing plates are installed and connected by means of bolts.
[0014] Through the above technical solution, the two arc-shaped plates are butted together by means of their respective splicing plates and then installed and connected by means of bolts.
[0015] As a preferred technical solution of the present invention, a guide tube is welded to one side of the inner wall of the corrugated compensator body.
[0016] Through the above technical solution, the guide tube can protect the bellows component and prevent the internal heat medium from directly eroding the inner wall of the bellows component.
[0017] As a preferred technical solution of the present invention, a plurality of the sheet-like brushes are placed between two arc-shaped plates.
[0018] Through the above technical solution, when the arc plates are installed, the sheet brushes are curled and stored inside the two arc plates. When the arc plates are removed, the sheet brushes stretch out. The sheet brushes are made of flexible material.
[0019] As a preferred technical solution of the present invention, both ends of the arc-shaped plate are snap-connected to the end faces of adjacent support rods.
[0020] Through the above technical solution, when the curved plate is installed, a rigid support can be formed between the two support rods.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. The utility model provides a plurality of ear plates, and the clamping columns, struts and curved plates between the relative ear plates. During the period of transportation and non-assembly use, the curved plates can be spliced and installed to form a rigid support between the two ear plates, thereby preventing the bellows components of the main body of the corrugated compensator from being stretched and deformed due to external forces such as shaking force, thereby avoiding increasing fatigue of the structure when not in use and maintaining the overall stability of the main body of the corrugated compensator. When assembled into the pipeline and put into use, the curved plates can be disassembled and elastically supported between the two ear plates by cooperating with the thin rods and the compression springs at both ends. Connection, during the telescopic compensation work of the corrugated compensator body, it does not affect its normal telescopic compensation, but also provides effective buffering, and at the same time limits the telescopic compensation to avoid damage to the structure at the extreme position. The multiple flaky brushes and blades provided on the side wall of the thin rod can be rotated by the airflow, thereby generating an airflow toward the corrugated compensator body, increasing the heat dissipation intensity. When the flaky brush contacts the surface of the corrugated compensator body, it can also brush the dust accumulated on its surface, reduce the accumulation of dust, which is beneficial to the heat dissipation process, avoid excessive telescopic deformation caused by excessive heat, and protect the compensator structure.
[0023] 2. The utility model can directly absorb the heat of the heat medium inside the corrugated compensator body by setting a plurality of annular heat sinks fixed on the outer wall of the corrugated compensator body and filling the heat-absorbing material between the two sides of the annular heat sink and the elastic ring, and conduct it out with the help of the annular heat sink. The heat-absorbing material is not affected by expansion and contraction, and at the same time covers the surface of the bellows component to absorb heat, thereby achieving a strong heat dissipation effect.

[0030] See also Figures 1 to 4 , the utility model provides a technical solution for a compensator that is convenient for heat dissipation:
[0031] Example 1:
[0032] according to Figure 1 、 Figure 2 and Figure 3 As shown, a compensator that is convenient for heat dissipation includes a corrugated compensator body 1, both ends of the corrugated compensator body 1 are fixedly connected with connecting flanges 2, the side walls of the two connecting flanges 2 are fixedly connected with multiple ear plates 4, two clamping columns 6 are provided between the two opposite ear plates 4, one end of the clamping column 6 is fixedly connected with a support rod 7, a thin rod 11 is provided between the two opposite support rods 7, and the side walls of the thin rod 11 are fixedly connected with multiple sheet brushes 9, the sheet brush 9 is made of flexible material, can be curled and stored between two arc plates 8, and can be unfolded when the arc plates 8 are disassembled, a blade 14 is embedded in the sheet brush 9, and an arc plate 8 is provided on both sides of the thin rod 11.
[0033] A card slot 5 is provided on one side wall of the ear plate 4, and the card column 6 matches the shape of the card slot 5. A side wall of the blade 14 is fixedly connected to the outer wall of the thin rod 11, and both ends of the thin rod 11 are rotatably connected to the end plate 13. A compression spring 12 is fixedly connected between the end plate 13 and the adjacent strut 7. The middle of the two side walls of the arc plate 8 is fixedly connected with a splicing plate 10, and the two adjacent splicing plates 10 are installed and connected by bolts. A plurality of sheet brushes 9 are placed between the two arc plates 8, and the two ends of the arc plate 8 are snap-fitted to the end faces of the adjacent struts 7.
[0034] When used specifically, the utility model is a compensator that is convenient for heat dissipation. During transportation when not in assembly use, the two curved plates 8 can be sleeved on both sides of the thin rod 11, and the two ends of the curved plates 8 are clamped with the adjacent struts 7. In this way, the two butted splicing plates 10 can be connected with the help of through bolts. In this way, the two installed curved plates 8 can form a rigid support between the two struts 7, so that the clamping columns 6 at both ends of the two struts 7 are inserted into the clamping grooves 5 of the two relative ear plates 4 to achieve rigid support for the two relative ear plates 4. In this way, during the transportation of the corrugated compensator main body 1, the bellows components in the corrugated compensator main body 1 will not be affected by shaking or other force impacts to expand, contract and fold back and forth, thereby avoiding increasing the fatigue of the structure when it is not put into use and maintaining the overall stability of the corrugated compensator main body 1. After being put into assembly and use, the two arc plates 8 can be disassembled, so that the two struts 7 are elastically connected with the help of the thin rod 11 and the compression springs 12 at both ends. During the telescopic compensation work of the corrugated compensator body 1, it does not affect its normal telescopic compensation, but also provides effective buffering, and limits the telescopic compensation to avoid damage to the structure at the extreme position. At the same time, during operation, multiple sheet brushes 9 on the thin rod 11 are exposed. When encountering ambient wind, the airflow blows multiple blades 14 to make the thin rod 11 rotate. In this way, the blades 14 and the sheet brushes 9 rotate, which can generate lateral wind force and blow towards the corrugated compensator body 1 to cool it. At the same time, the sheet brush 9 contacts the corrugated compensator body 1 to brush the dust on its surface, reduce dust accumulation, and thus make the heat dissipation efficiency better.

The heat-absorbing material 17 is a plurality of uniform granular structures made of thermally conductive silicone, which is filled between the two sides of the annular heat sink 15 and the elastic ring 16. It can effectively absorb and conduct heat, and the granular structure is not affected by expansion and contraction and has a long durability. A guide tube 3 is welded to one side of the inner wall of the corrugated compensator body 1.
[0037] During specific use, the utility model is a compensator that is easy to dissipate heat. During use, the bellows component of the bellows compensator body 1 will undergo compensatory expansion and contraction, and multiple annular heat sinks 15 will fit the side wall of the bellows component to absorb and conduct heat, thereby achieving effective heat dissipation of the internal heat medium and preventing the bellows compensator body 1 from continuously receiving a large amount of heat and causing excessive expansion and contraction to cause structural deformation. At the same time, the heat-absorbing material 17 filled between the two sides of the annular heat sink 15 and the elastic ring 16 is not affected by the expansion and contraction, and at the same time covers the surface of the bellows component to absorb heat. The annular heat sink 15 inserted inside it then conducts the absorbed heat away, thereby achieving efficient heat dissipation.
