Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly to a dew prevention device for pipelines. Background Art

[0002] The water supply and drainage pipeline project is a pipeline system project for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting, and discharging industrial wastewater, domestic sewage, and rainwater. In buildings, the water supply and drainage pipelines often have the temperature of their pipe walls lower than the external ambient temperature, causing moisture in the external air to condense on the outer surface of the water pipes. However, in the prior art, the drainage pipes still cannot achieve the effect of preventing condensation, which reduces the service life of the drainage pipes under condensation. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a dew prevention device for pipelines, which solves the problem of dew condensation on the outer wall of the water supply and drainage pipelines. By using the dew prevention device, the condensation of water dew on the outer wall of the pipeline is avoided, so as to extend the service life of the pipeline, ensure the normal operation of the water supply and drainage system, and the device has a simple structure, is easy to implement, and has strong adaptability.

[0004] The technical solution to achieve the above purpose is as follows:

[0005] The present invention provides a dew prevention device for pipelines, including:

[0006] Two clamping plates that are oppositely arranged and rotatably connected on the opposite sides, and by rotating the two clamping plates, a surrounding space for clamping the pipeline is formed;

[0007] A protective layer that fits on the inner walls of the two clamping plates. When the two clamping plates enclose to form a surrounding space, the two ends of the protective layer are in contact and enclose in a ring shape, and the joint seam of the protective layer is staggered from the joint seam of the two clamping plates;

[0008] A water receiving trough fixed below the clamping plate and corresponding to the end of the surrounding space; and

[0009] A support frame with its bottom end fixed to the water receiving trough and its top end located above the clamping plate for connecting to the main structure above the pipeline.

[0010] The present invention adopts an anti-condensation device for pipelines. By using clamping plates to clamp the pipelines, at this time, the protective layer adheres to the surface of the pipelines. And because the fitting seams of the protective layer are staggered from the fitting seams of the clamping plates, the tightness of the wrapping of the pipelines is further improved. In addition, when dew forms on the outer wall of the pipelines, the dew can flow along the outer wall of the pipelines to the ends of the clamping plates and flow downward into the water receiving tank, thereby preventing water accumulation around the pipelines. And the support frame is connected to the main structure to protect the pipelines, solving the problem of dew condensation on the outer wall of the water supply and drainage pipelines. By using the anti-condensation device, the condensation of water dew on the outer wall of the pipelines is avoided, so as to extend the service life of the pipelines and ensure the normal operation of the water supply and drainage system. And the device has a simple structure, is easy to implement, and has strong adaptability.

[0011] A further improvement of the anti-condensation device for pipelines of the present invention is that it further includes a sleeve fixed to the inner wall of the clamping plate and passing through the protective layer, a movable rod inserted into the sleeve, and a first spring connected between the bottom end of the sleeve and the corresponding end of the movable rod. The end of the movable rod protruding from the sleeve abuts against the side of the pipeline.

[0012] A further improvement of the anti-condensation device for pipelines of the present invention is that it further includes an abutting plate fixed to the exposed end of the movable rod and in an inverted V shape, and a rubber pad fixed to the end of the abutting plate away from the movable rod. The rubber pad abuts against the side of the pipeline.

[0013] A further improvement of the anti-condensation device for pipelines of the present invention is that it further includes a ventilation pipe with one end communicating with the enclosed space and the other end extending above the water receiving tank, and a negative pressure fan installed at the end of the ventilation pipe close to the water receiving tank. The negative pressure fan blows air into the enclosed space through the ventilation pipe.

The mounting plate is for connecting with the main structure;

[0016] By the second spring expanding and contracting and the adjusting rod moving back and forth along the first fixed pipe and the second fixed pipe, the acting force of the main structure is offset.

[0017] A further improvement of the anti-condensation device for pipelines according to the present invention lies in that it further includes a first through hole formed in the first fixing pipe corresponding to the adjusting rod, a second through hole formed in the second fixing pipe corresponding to the adjusting rod, and a sealing plate fixed to the end of the adjusting rod. The adjusting rod passes through the first through hole and the second through hole, and the diameter of the sealing plate is larger than the diameters of the first through hole and the second through hole to prevent the adjusting rod from slipping out of the first fixing pipe and the second fixing pipe.

By using a clamping plate to clamp the pipe, the protective layer is attached to the surface of the pipe, and the bonding seam of the protective layer is staggered with the bonding seam of the clamping plate to further improve the tightness of the pipe coating. In addition, when dew is generated on the outer wall of the pipe, the dew can flow along the outer wall of the pipe to the end of the clamping plate and flow downward into the water receiving trough, thereby preventing water from accumulating around the pipe. The support frame is connected to the main structure to protect the pipe, solving the problem of dew condensation on the outer wall of the water supply and drainage pipe. The anti-condensation device prevents condensation on the outer wall of the pipe, thereby extending the service life of the pipe and ensuring the normal operation of the water supply and drainage system. The device has a simple structure, is easy to implement, and has strong adaptability. The anti-condensation device for pipes of the present invention is described below in conjunction with the accompanying drawings.

[0032] See also Figure 1 , Figure 1 This is a three-dimensional diagram of the anti-condensation device for pipelines of the present invention. Figure 1 , the anti-condensation device for pipelines of the present invention is described.

[0033] like Figures 1 to 6 As shown, the anti-condensation device for pipelines of the present invention comprises:

[0034] Two clamping plates 11 are arranged opposite to each other and are rotatably connected on opposite sides. By rotating the two clamping plates 11, an enclosed space for the jacketed pipe is formed;

[0035] The protective layer 111 is attached to the inner walls of the two clamping plates 11. When the two clamping plates 11 are closed to form an enclosed space, the two ends of the protective layer 111 are attached to each other and closed to form a ring shape, and the bonding seam of the protective layer 111 is staggered with the bonding seams of the two clamping plates 11.

[0036] A water receiving trough 12 fixed below the clamping plate 11 and correspondingly located at the end of the enclosed space; and

[0037] The support frame 13 has a bottom end fixed to the water receiving tank 12 and a top end located above the clamping plate 11 for connection with the main structure above the pipeline.

[0038] Specifically, the clamping plate 11 is arranged obliquely so that one end of the enclosed space is higher than the other end of the enclosed space, so that dew on the side wall of the pipeline can flow into the water receiving groove 12.

[0039] As a preferred embodiment of the present invention, it further includes a sleeve 112 fixed to the inner wall of the clamping plate 11 and passing through the protective layer 111, a movable rod 113 inserted into the sleeve 112, and a first spring connected between the bottom end of the sleeve 112 and the corresponding end of the movable rod 113. The end of the movable rod 113 protruding from the sleeve 112 abuts against the side of the pipe.

[0040] Specifically, it further includes an abutting plate 1131 fixed to the exposed end of the movable rod 113 and in an inverted V shape, and a rubber pad fixed to the end of the abutting plate 1131 away from the movable rod 113. The rubber pad abuts against the side of the pipe.

[0041] Furthermore, it further includes a ventilation pipe 14 with one end communicating with the enclosed space and the other end extending above the water receiving tank 12, and a negative pressure fan 141 installed at the end of the ventilation pipe 14 close to the water receiving tank 12. The negative pressure fan 141 blows air into the enclosed space through the ventilation pipe 14.

[0042] Specifically, it further includes a heating pipe installed on the inner wall of the ventilation pipe 14.

[0043] Preferably, water receiving tanks 12 are installed at both ends of the clamping plate 11, and ventilation pipes 14 are installed. The ends of the two ventilation pipes 14 where the negative pressure fans 141 are installed are arranged in opposite directions, that is, the two negative pressure fans 141 face away from each other.

[0044] Furthermore, the support frame 13 includes two first fixed pipes 131 arranged opposite to each other and fixed to the top of the water receiving tank 12, an adjusting rod 133 with its bottom end slidably connected to the first fixed pipe 131, a second fixed pipe 132 vertically arranged at the top of the adjusting rod 133 and slidably connected to the adjusting rod 133, a second spring 134 connected between the first fixed pipe 131 and the second fixed pipe 132, and a mounting plate 135 fixedly connected to the tops of the two second fixed pipes 132. The mounting plate 135 is for connecting with the main structure;

[0045] By the telescoping of the second spring 134 and the reciprocating movement of the adjusting rod along the first fixed pipe 131 and the second fixed pipe 132, the acting force of the main structure is offset.

[0046] Specifically, it further includes a first through hole formed in the first fixed pipe 131 corresponding to the adjusting rod 133, a second through hole formed in the second fixed pipe 132 corresponding to the adjusting rod, and a sealing plate 1331 fixed to the end of the adjusting rod 133. The adjusting rod 133 passes through the first through hole and the second through hole, and the diameter of the sealing plate 1331 is larger than the diameters of the first through hole and the second through hole to prevent the adjusting rod 133 from slipping out of the first fixed pipe 131 and the second fixed pipe 132.

[0047] Further, the protective layer 111 includes a heat-insulating layer bonded to the inner wall of the clamping plate 11, a waterproof layer attached to the inner side of the heat-insulating layer, and a tin foil layer attached to the inner side of the waterproof layer.

[0048] Further, it also includes two fixing plates 114 fixed to the corresponding sides of the clamping plate 11 and bolts for screwing into the fixing plates 114;

[0049] By rotating the two clamping plates 11 to enclose a surrounding space and the two fixing plates 114 are in contact with each other, and then the bolts are screwed into the two fixing plates 114 to fixedly connect the two clamping plates 11.

[0050] The specific implementation manner of the present invention is as follows:

[0051] Connect the mounting plate 135 of the support frame 13 to the main structure above the pipeline. When the main structure is stressed and vibrates, the adjusting rod 133 moves back and forth along the first fixed pipe 131 and the second fixed pipe 132, and the second spring 134 expands and contracts to offset the vibration of the main structure, thereby protecting the pipeline;

[0052] Place the pipeline between the two clamping plates 11, and then rotate the clamping plates 11 so that the two clamping plates 11 are joined to form a surrounding space and clamp the pipeline. At this time, the two ends of the protective layer 111 are also in contact with each other and enclose in a ring shape, and the joint seam of the protective layer 111 is staggered from the joint seam of the clamping plate 11;

[0053] At this time, the movable rod 113 moves back and forth along the sleeve 112 and the first spring expands and contracts, so that the abutting plate 1131 abuts against the side wall of the pipeline, thereby further fixing the pipeline. Fix the two fixing plates 114 by bolts so that the two clamping plates 11 are fixedly connected. Since the joint seam of the protective layer 111 is staggered from the joint seam of the clamping plate 11, the sealing performance of the pipeline can be improved;

[0054] Turn on the negative pressure fan 141 and the heating pipe to input hot air into the surrounding space to achieve dehumidification and exhaust of the surrounding space, prevent dew from freezing on the outer wall of the pipeline, and the melted dew can also flow along the outer wall of the pipeline to the end of the clamping plate 11 and fall into the water receiving tank 12.

[0055] The present invention also provides a method for using an anti-condensation device for a pipeline, and the method includes the following steps:

[0056] Provide the anti-condensation device, rotate the two clamping plates 11 so that the two clamping plates 11 enclose a surrounding space and clamp the pipeline, and the protective layer 11 covers the pipeline;

[0057] Fix the support frame 13 to the main structure above the pipeline, and the dew on the pipeline flows along the protective layer 111 to the end of the clamping plate 11 and flows into the water receiving tank 12.

[0058] The specific operation method provided by the present invention is actually implemented as follows:

[0059] Connect the mounting plate 135 of the support frame 13 to the main structure above the pipeline. When the main structure is stressed and vibrates, the adjusting rod 133 moves back and forth along the first fixed pipe 131 and the second fixed pipe 132, and the second spring 134 expands and contracts to offset the vibration of the main structure, thereby protecting the pipeline;

[0060] Place the pipeline between the two clamping plates 11, and then rotate the clamping plates 11 so that the two clamping plates 11 are joined together to form an enclosed space and clamp the pipeline. At this time, the two ends of the protective layer 111 also abut and enclose into a ring shape, and the joint seam of the protective layer 111 is staggered from the joint seam of the clamping plate 11;

[0061] At this time, the movable rod 113 moves back and forth along the sleeve 112 and the first spring expands and contracts so that the abutting plate 1131 abuts against the side wall of the pipeline, thereby further fixing the pipeline. Use bolts to fixedly connect the two fixing plates 114 so that the two clamping plates 11 are fixedly connected. Since the joint seam of the protective layer 111 is staggered from the joint seam of the clamping plate 11, the sealing performance of the pipeline can be improved;

[0062] Turn on the negative pressure fan 141 and the heating pipe to input hot air into the enclosed space to achieve moisture and exhaust gas discharge in the enclosed space, prevent dew from freezing on the outer wall of the pipeline, and the melted dew can also flow along the outer wall of the pipeline to the end of the clamping plate 11 and fall into the water receiving tank 12.

[0063] The present invention has been described in detail above in combination with the embodiments of the drawings. Those of ordinary skill in the art can make various variations of the present invention according to the above description.
