Description

Technical Field

[0001] This invention relates to the field of pipeline technology, and in particular to a five-constant heat-insulating and noise-absorbing pipeline. Background Technology

[0002] The cold air produced by refrigeration equipment usually needs to be transported through pipelines. Under normal circumstances, because the cold air produced by refrigeration equipment flows at a high speed, it will generate a lot of noise when flowing in the pipeline due to friction and other reasons. Moreover, if the pipeline is too long, the temperature will also be easily lost. Therefore, a new type of pipeline is needed to solve this problem. Summary of the Invention

[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a five-constant heat-insulating and sound-absorbing pipe.

[0005] To achieve the above objectives, the technical solution of the present invention is: a five-constant heat-insulating and sound-absorbing pipe, comprising a pipe body, the pipe body comprising a wide pipe section and a narrow pipe section, the wide pipe section being between two narrow pipe sections, the pipe body comprising two halves, the two halves being fixedly connected to each other, each of the two halves being provided with a heat-insulating mechanism on its outer side, the wide pipe section being provided with a porous mechanism for dividing the airflow into multiple airflow streams, the two halves being fixedly connected to each other.

[0006] By adopting the above technical solution, the combination of wide and narrow pipe sections creates a tortuous channel inside the pipe. When the airflow enters the wide pipe section from the narrow pipe section, it passes through a porous mechanism, which divides the airflow into multiple streams and diffuses them into larger streams. Then, it re-enters the narrow pipe section, causing the diffused airflow to be re-gathered. It then re-enters the wide pipe section and diffuses again through the porous mechanism. This process is repeated to weaken the energy of the airflow, reduce its wind speed, and achieve a noise reduction effect. The external insulation mechanism prevents heat loss.

[0007] Preferably, the porous mechanism includes a sound-absorbing plate with a plurality of dividing holes, and each of the two halves is provided with a locking mechanism for engaging the sound-absorbing plate. This invention utilizes the dividing holes to ensure that airflow can only pass through the dividing holes when passing through the sound-absorbing plate, thereby achieving airflow segmentation.

[0008] Preferably, the locking mechanism includes two limiting plates, with a limiting groove formed between the two limiting plates for the silencing plate to engage. This invention utilizes the limiting groove to position the silencing plate. When the two halves are interlocked, both the upper and lower ends of the silencing plate engage with the limiting grooves on the two halves, thereby fixing the silencing plate and simultaneously positioning the two halves through the silencing plate.

[0009] Preferably, the insulation mechanism includes an outer shell, with the outer shell fixedly connected to the outer sides of both halves. A filling cavity is formed between the outer shell and the halves by a support plate, and the filling cavity is filled with insulation material. The support plate forms a filling cavity between the halves and the outer shell, which can be filled with insulation material to give the pipe a good insulation effect. The insulation material can be polyurethane foam or composite silicate, etc.

[0010] Preferably, both ends of the filling cavity are sealed by sealing plates, and the sealing plates are fixedly connected to the half-body. This invention utilizes sealing plates to seal the filling cavity after it is filled with insulation material, and the seal is fixed by adhesive.

[0011] Preferably, the two halves are bonded together by the sealing plate.

[0012] Preferably, a silencing mechanism is provided at one end of the pipe body. The silencing mechanism includes a plurality of blocking mechanisms, which are respectively and spaced apart on the two side walls of the pipe body. Adjacent blocking mechanisms are located on different side walls of the pipe body. Each blocking mechanism includes a fixed plate and a sliding plate, and the sliding plate is slidably connected to the fixed plate. The pipe body is provided with a driving mechanism for driving each sliding plate to slide. This invention utilizes staggered blocking mechanisms to make the path in the air duct tortuous. When the airflow passes through the air duct, it is blocked by the blocking mechanisms and its speed is weakened, thereby achieving a silencing effect. The blocking mechanism includes a sliding plate and a fixed plate. The sliding plate can be driven by the driving mechanism to slide, thereby controlling the distance between it and the side wall of the air duct, thus adjusting the ventilation volume and achieving the effect of adjusting the air output.

[0013] Preferably, the driving mechanism includes a driving rope, one end of which is fixedly connected to the tube body. The driving rope abuts against each of the sliding plates, and an elastic element is provided between each sliding plate and the tube body. An adjustment mechanism for pulling the driving rope is provided at the outlet of the tube body. This invention fixes one end of the driving rope to the air duct, and the other end can be pulled by the adjustment mechanism. After tensioning, the driving rope bends and abuts against each sliding plate. When the driving rope is pulled, it gradually straightens, thereby pushing the sliding plate to slide against the elastic force of the elastic element. At this time, the distance between the sliding plate and the side wall of the air duct increases, and the airflow increases. When the driving rope is relaxed, the elastic element releases its elastic force, causing the sliding plate to slide closer to the side wall of the air duct, causing the relaxed driving rope to re-tension, reducing the distance between the sliding plate and the side wall of the air duct, and thus reducing the airflow.

[0014] Preferably, the adjusting mechanism includes a screw and a slider. The screw is rotatably connected to the tube body, and the slider is slidably connected to the half-body. The slider is threadedly connected to the screw, and one end of the drive rope is connected to the slider. This invention, by rotating the screw, utilizes the threaded pair between the slider and the screw to drive the slider to slide, thereby pulling one end of the drive rope to move. This allows control over the tension or slack of the drive rope. The screw is driven by a servo motor, and remote control is achieved through circuit control.

[0015] Preferably, a guide wheel is provided between the screw and the blocking mechanism, and the drive rope passes around the guide wheel and connects to the slider. This invention utilizes the guide wheel to fix a point on the drive rope, thereby enabling more stable control of the length the drive rope is pulled when the slider pulls the drive rope.

[0016] In summary, the beneficial effects of this invention are: 1. By combining wide and narrow pipe sections, a tortuous channel is formed inside the pipe. When the airflow enters the wide pipe section from the narrow pipe section, it passes through a porous mechanism, which divides the airflow into multiple streams and diffuses them into larger streams. Then, it re-enters the narrow pipe section, causing the diffused airflow to be re-gathered. It then re-enters the wide pipe section and diffuses again through the porous mechanism. This process is repeated to weaken the energy of the airflow and reduce its wind speed, thus achieving a noise reduction effect. The outer insulation mechanism prevents heat loss.

[0017] 2. By using staggered blocking mechanisms, the path within the air duct can be made tortuous. When the airflow passes through the air duct, it will be blocked by the blocking mechanisms and its speed will be weakened, thereby achieving the effect of noise reduction.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0029] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] like Figure 1-5 As shown, a five-constant heat-insulating and sound-absorbing pipe includes a pipe body 18, which includes a wide pipe section 1 and a narrow pipe section 2. The wide pipe section 1 is located between the two narrow pipe sections 2. The pipe body 18 includes two halves 3, which are fixedly connected to each other. Each half 3 is provided with a heat-insulating mechanism on its outer side. The wide pipe section 1 is provided with a porous mechanism for dividing the airflow into multiple airflow streams. The two halves 3 are fixedly connected to each other.

[0031] By adopting the above technical solution, the combination of wide pipe section 1 and narrow pipe section 2 creates a tortuous channel inside the pipe. When the airflow enters the wide pipe section 1 from the narrow pipe section 2, it passes through a porous mechanism. The porous mechanism divides the airflow into multiple streams and diffuses them into larger streams. Then, it re-enters the narrow pipe section 2, causing the diffused airflow to be re-gathered. It then re-enters the wide pipe section 1 and diffuses again through the porous mechanism. This process is repeated to weaken the energy of the airflow and reduce its wind speed, thus achieving a noise reduction effect. The outer insulation mechanism prevents heat loss.

[0032] The porous mechanism includes a sound-absorbing plate 4, which has several dividing holes 5. Both halves 3 are equipped with a locking mechanism for engaging the sound-absorbing plate 4. The dividing holes 5 ensure that airflow can only pass through the dividing holes 5 when passing through the sound-absorbing plate 4, thus achieving airflow segmentation.

[0033] The locking mechanism includes two limiting plates 6, with a limiting groove formed between the two limiting plates 6 for the muffler plate 4 to be inserted. The limiting groove is used to position the muffler plate 4. When the two halves 3 are interlocked, both the upper and lower ends of the muffler plate 4 are inserted into the limiting grooves on the two halves 3, thereby fixing the muffler plate 4 and also positioning the two halves 3 through the muffler plate 4.

[0034] The insulation mechanism includes an outer shell 7, with the outer shell 7 fixedly connected to the outer sides of two halves 3. A filling cavity 9 is formed between the outer shell 7 and the halves 3 by a support plate 8, and the filling cavity 9 is filled with insulation material. The support plate 8 forms a filling cavity 9 between the halves 3 and the outer shell 7, which can be filled with insulation material to give the pipe body 18 a good insulation effect. The insulation material can be polyurethane foam or composite silicate, etc.

[0035] Both ends of the filling cavity 9 are sealed by sealing plates 10, which are fixedly connected to the half-body 3. The sealing plates 10 can be used to seal the filling cavity 9 after it is filled with insulation material, and the seal is fixed by adhesive.

[0036] The two halves 3 are bonded together by a sealing plate 10.

[0037] A silencing mechanism is provided at one end of the duct body 18. The silencing mechanism includes several blocking mechanisms, which are spaced apart on the two side walls of the duct body 18. Adjacent blocking mechanisms are located on different side walls of the duct body 18. Each blocking mechanism includes a fixed plate 11 and a sliding plate 12, with the sliding plate 12 slidably connected to the fixed plate 11. The duct body 18 is provided with a driving mechanism for driving each sliding plate 12 to slide. By using the staggered blocking mechanisms, the path within the air duct can be made tortuous. When the airflow passes through the air duct, it is blocked by the blocking mechanisms and its speed is weakened, thereby achieving the effect of silencing. The blocking mechanism includes a sliding plate 12 and a fixed plate 11. The sliding plate 12 can be driven by the driving mechanism to slide, thereby controlling the distance between it and the side wall of the air duct, thus adjusting the ventilation volume and achieving the effect of adjusting the air volume.

[0038] The drive mechanism includes a drive rope 13, one end of which is fixedly connected to the tube body 18. The drive rope 13 abuts against each sliding plate 12, and an elastic element 14 is provided between each sliding plate 12 and the tube body 18. An adjustment mechanism for pulling the drive rope 13 is provided at the outlet of the tube body 18. By fixing one end of the drive rope 13 to the air duct and pulling the other end through the adjustment mechanism, the drive rope 13 is tensioned and bends to abut against each sliding plate 12. When the drive rope 13 is pulled, it gradually straightens, thereby pushing the sliding plate 12 to slide against the elastic force of the elastic element 14. At this time, the distance between the sliding plate 12 and the side wall of the air duct increases, and the air volume increases. When the drive rope 13 is relaxed, the elastic element 14 releases its elastic force, causing the sliding plate 12 to slide towards the side wall of the air duct, so that the relaxed drive rope 13 is re-tensioned, and the distance between the sliding plate 12 and the side wall of the air duct decreases, at which point the air volume decreases.

[0039] The adjustment mechanism includes a screw 15 and a slider 16. The screw 15 is rotatably connected to the tube 18, and the slider 16 is slidably connected to the half-body 3. The slider 16 is threadedly connected to the screw 15, and one end of the drive rope 13 is connected to the slider 16. By rotating the screw 15, the threaded pair between the slider 16 and the screw 15 can be used to drive the slider 16 to slide, thereby pulling one end of the drive rope 13 to move, thus controlling the tension or slack of the drive rope 13. The screw 15 is driven by a servo motor and can be remotely controlled from the outside in conjunction with circuit control.

[0040] A guide wheel 17 is provided between the screw 15 and the blocking mechanism. The drive rope 13 passes around the guide wheel 17 and is connected to the slider 16. The guide wheel 17 can fix a point on the drive rope 13, so that when the slider 16 pulls the drive rope 13, the length of the drive rope 13 being pulled can be controlled more stably.

[0041] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
