Description

Technical Field

[0001] This disclosure relates to the field of pipeline-specific electric heating tape technology, and in particular to a pipeline heating tape. Background Technology

[0002] Cold protection and frost prevention are important tasks in power plants, especially in northern regions where the ambient temperature is low and the winter is long, making it easier for water supply and drainage pipes to freeze, which seriously affects the safe and stable operation of generator units.

[0003] Pipeline freezing is a common problem in thermal power plants, especially discontinuous water supply pipelines and compressed air supply pipelines from outside the plant to important instruments. Pipeline freezing is very likely to occur when the ambient temperature is low in winter. Therefore, the application of reliable and effective electric heating tape for pipeline antifreeze in power plants is particularly important.

[0004] In existing technologies, power plants commonly use circular pipes for water supply and drainage. The commonly used electric heating tape is flat, approximately 2mm thick and 10mm wide, resulting in very poor heat tracing performance; often, it's "tracing the heat but not actually heating." Electric heating tapes can be installed in two ways: one is by direct contact with the pipe and securing it with tape; the other is by wrapping the tape around the pipe. The advantages of these two methods are ease of installation and cost savings. The disadvantage is that the contact area between the heating tape and the pipe is small, failing to provide adequate heat tracing, especially in cold northern regions where the heat tracing effect is poor. Utility Model Content

[0005] This disclosure is made in view of the above-mentioned problems. This disclosure provides a pipeline tracing cable.

[0006] According to one aspect of this disclosure, a pipe tracing cable is provided, comprising:

[0007] The heat tracing tape is sheet-shaped and has internal wires that can conduct electricity and generate heat, and is used to wrap pipes.

[0008] The heat tracing cable is ring-shaped and elastic, and can be fitted onto a connecting pipe. Alternatively, the heat tracing cable may have multiple clips, which are respectively located at both ends and the middle of the heat tracing cable, and can surround the connecting pipe.

[0009] Furthermore, according to one aspect of the pipe tracing cable, the clip has a first opening when it is wrapped around the pipe, and the size of the first opening is changed to adjust the tightness of the clip.

[0010] Furthermore, according to one aspect of the pipe tracing cable of this disclosure, the angle of the first opening is 40-50% of 360 degrees.

[0011] In addition, the pipeline tracing cable according to one aspect of this disclosure also includes:

[0012] A fastening adjustment device is disposed at the end of the buckle and is used to adjust the size of the first opening.

[0013] Furthermore, according to one aspect of the pipe tracing cable of this disclosure, the tracing cable is provided with a clip every 500-1000 mm along its length.

[0014] Furthermore, according to one aspect of the pipe tracing tape of the present disclosure, when the tracing tape is elastic, a second opening is provided when the tracing tape is wrapped around the pipe, and the angle of the second opening is 10-30% of 360 degrees.

[0015] Furthermore, according to one aspect of the present disclosure, when the tracing cable is elastic, the annular inner diameter of the tracing cable in its natural state is not greater than the outer diameter of the pipe.

[0016] Furthermore, according to one aspect of this disclosure, the width of the pipe tracing tape is 1 / 3 to 2 / 3 of the circumference of the pipe.

[0017] In addition, the pipeline tracing cable according to one aspect of this disclosure also includes:

[0018] A DCS control device is electrically connected to the heat tracing cable and is used to control the working status of the heat tracing cable.

[0019] In addition, the pipeline tracing cable according to one aspect of this disclosure also includes:

[0020] A power source, which is electrically connected to the heat tracing cable, supplies power to the heat tracing cable.

[0021] According to the pipeline tracing cable of the present disclosure, by setting a sheet-like tracing cable, the contact area between the tracing cable and the pipeline is large, which improves the heat tracing effect and overcomes the problems of small contact area and poor heat tracing effect of electric tracing cables in the prior art. It effectively solves the problem of pipeline freezing in winter and ensures the safe and stable operation of the unit.

[0030] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0031] This disclosure provides a pipeline heat tracing cable with a large contact area with the pipeline, which improves the heat tracing effect, effectively solves the problem of pipeline freezing in winter, and ensures the safe and stable operation of the unit.

[0032] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment of the present disclosure provides a pipe tracing heat pack, including: a tracing heat pack 3, which is sheet-shaped and has internal wires that can conduct electricity to generate heat, used to wrap the pipe 1; the tracing heat pack 3 can be set as a rectangle, with its length set along the axial direction of the pipe 1, and can be connected to an external power supply 5.

[0034] In order to fix the heating tape 3 to the pipe 1, such as Figure 1 As shown, the heat tracing cable 3 can be set as a ring and has elasticity, that is, the heat tracing cable 3 can undergo elastic deformation and can be fitted onto the connecting pipe 1.

[0035] Or, such as Figure 2As shown, the heat tracing cable 3 is provided with multiple clips 2, which are respectively located at both ends and the middle of the heat tracing cable 3, and can surround the connecting pipe 1.

[0036] The heat tracing cable 3 is equipped with clips 2 at both ends and in the middle to ensure that the heat tracing cable 3 is securely installed on the pipe 1 and that the heat tracing cable 3 is in close contact with the pipe 1. The clips 2 can be made of metal, such as stainless steel, which has high structural strength and ensures that the heat tracing cable 3 is securely installed on the pipe 1.

[0037] Clips 2 can also be installed on the elastic heat tracing cable 3, combining the two installation and fixing methods to further improve the firmness of the connection between the heat tracing cable 3 and the pipe 1.

[0038] In some possible implementations, such as Figure 2 As shown, when the buckle 2 is wrapped around the pipe 1, a first opening 7 is provided, and the size of the first opening 7 is changed to adjust the tightness of the buckle 2.

[0039] When the buckle 2 is not wrapped around the pipe 1, it is in the shape of a strip, with parts A and C at the two ends and part B in the middle. When it is wrapped around the pipe 1, the gap between parts A and C is the first opening 7. When the first opening 7 becomes smaller, the tightness of the buckle 2 is increased. When the first opening 7 becomes larger, the tightness of the buckle 2 is decreased.

[0040] In some possible implementations, such as Figure 2 As shown, the angle of the first opening 7 accounts for 40-50% of 360 degrees, that is, the angle of the first opening 7 around the pipe 1 accounts for 40-50%. This angle range can ensure that the heat tracing cable 3 is firmly installed on the pipe 1.

[0041] In some possible implementations, such as Figure 2 As shown, the pipe tracing cable also includes a fastening adjustment device 6, which is located at the end of the clip 2 and is used to adjust the size of the first opening 7. The fastening adjustment device 6 may be equipped with a bolt and a nut. The nut is connected to the first end of the clip 2, and a connecting ring is provided at the second end of the clip 2. The bolt is inserted into the connecting ring and connected to the nut. By adjusting the connection length between the bolt and the nut, the size of the first opening 7 can be adjusted.

[0042] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, a clip 2 is provided every 500-1000mm along the length of the heat tracing cable 3. This distance range can ensure that the heat tracing cable 3 is securely installed on the pipe 1.

[0043] In some possible implementations, such as Figure 1As shown, when the heat tracing cable 3 is elastic, a second opening 8 is provided when the heat tracing cable 3 is wrapped around the pipe 1. The angle of the second opening 8 accounts for 10-30% of 360 degrees, that is, the angle of the second opening 8 around the pipe 1 accounts for 10-30%. This angle range can ensure that the heat tracing cable 3 is firmly installed on the pipe 1.

[0044] In some possible implementations, such as Figure 1 As shown, when the heat tracing cable 3 is inherently elastic, its annular inner diameter in its natural state is no greater than the outer diameter of the pipe 1. This structural relationship ensures that the heat tracing cable 3 is securely installed on the pipe 1. The inner diameter of the heat tracing cable 3 needs to be designed and manufactured according to different pipe diameter models.

[0045] In some possible implementations, such as Figure 1 , Figure 2 As shown, the width of the heat tracing cable 3 is 1 / 3 to 2 / 3 of the circumference of the pipe 1. This structural relationship can ensure that the heat tracing cable 3 forms an effective heating range for the pipe 1.

[0046] In some possible implementations, such as Figure 1 , Figure 2 As shown, the pipeline heat tracing cable also includes a DCS control device 4, which is electrically connected to the heat tracing cable 3 and is used to control the working status of the heat tracing cable 3.

[0047] When the temperature of pipe 1 is low, the heat tracing cable 3 is activated to heat pipe 1. When the temperature of pipe 1 rises, the heat tracing cable 3 can be stopped to avoid energy waste.

[0048] In some possible implementations, such as Figure 1 , Figure 2 As shown, the pipeline heating cable also includes a power source 5, which is electrically connected to the heating cable 3 to supply power to the heating cable 3. The power source 5 can be a battery, a solar cell, or other form of external power source.

[0049] The pipeline heating cable according to embodiments of the present disclosure has been described above with reference to the accompanying drawings, and has the following advantages:

[0050] By setting up sheet-like heating tapes, the contact area between the heating tape and the pipeline is larger, which improves the heat tracing effect and overcomes the problems of small contact area and poor heat tracing effect of existing electric heating tapes. This effectively solves the problem of pipeline freezing in winter and ensures the safe and stable operation of the unit.
