Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, and more specifically to a high-efficiency heat-insulating pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

[0003] Deficiencies of existing technology: Under the existing technology, when some pipelines are transporting gas and liquid, the staff needs to keep the temperature in the pipeline within the standard range. When insulating the pipeline, the existing method usually makes changes to the material of the pipeline itself, and prevents the temperature of the pipeline from radiating to the external environment by making a pipeline insulation layer. However, this method often has poor insulation effect when encountering some extreme environments, so that the temperature in the pipeline is not within the standard range, affecting the transportation of gas or liquid in the pipeline. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a high-efficiency heat-insulating pipeline to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a high-efficiency heat-insulating pipe, comprising a pipe body and a control unit, wherein a heat-conducting silicone pad is arranged on the outside of the pipe body, a heating wire is inserted inside the heat-conducting silicone pad, a temperature sensor is fixedly installed inside the pipe body, the temperature sensor is equipped with a signal transmitting module, the temperature sensor is used to monitor the temperature inside the pipe body in real time, and the control unit is used to perform closed-loop control of the temperature inside the pipe body according to the monitoring result of the temperature sensor.

[0006] Preferably, six heating wires are provided, and the six heating wires are distributed in an array in the circumferential direction of the pipeline body, and a PVC sheath is provided on the outer side of the thermally conductive silicone pad.

[0007] Preferably, the signal transmitting module is fixedly mounted on the surface of the PVC sheath, and the input end of the signal transmitting module is electrically connected to the output end of the temperature sensor via a first wiring harness.

[0008] Preferably, the control unit includes a control module, a signal receiving module and a main wiring harness, the output end of the signal receiving module and the input end of the control module are electrically connected through a second wiring harness, one end of the main wiring harness is electrically connected to the output end of the control module, one end of the six heating wires are gathered together, and the other end of the main wiring harness is electrically connected to one end of the heating wire.

[0009] Technical effects and advantages of the utility model:

[0010] When the utility model is in use, the heat generated by the electric heating wire can be transferred to the thermally conductive silicone pad. Since the thermally conductive silicone pad tightly wraps the pipeline body, the heat generated by the thermally conductive silicone pad is then transferred to the pipeline body, which plays a role in heat preservation of the pipeline body. The temperature sensor monitors the temperature inside the pipeline body in real time. The signal receiving module and the signal receiving module cooperate with each other to transmit the monitored temperature information to the control module. If the control module finds that the real-time temperature inside the pipeline body is lower than the standard temperature value, the control module increases the current of the total wire harness, the current passing through the electric heating wire increases, and the heat generated by the electric heating wire becomes larger, thereby increasing the temperature inside the pipeline body. If the control module finds that the real-time temperature inside the pipeline body is higher than the standard temperature value, the control module reduces the current of the total wire harness. Similarly, the temperature inside the pipeline body is reduced. This design solves the shortcomings of the prior art. The temperature inside the pipeline body can be fed back to the control module in real time through the temperature sensor, and the control module then changes and adjusts the temperature inside the pipeline body in real time, realizing closed-loop regulation and control of the temperature inside the pipeline body, and keeping the temperature within the standard range, thereby achieving the purpose of efficient heat preservation.

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The high-efficiency thermal insulation pipe involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0016] The utility model provides a high-efficiency heat-insulating pipeline, comprising a pipeline body 1 and a control unit 6, a heat-conducting silicone pad 2 is arranged on the outside of the pipeline body 1, a heating wire 3 is inserted inside the heat-conducting silicone pad 2, a temperature sensor 4 is fixedly installed inside the pipeline body 1, the temperature sensor 4 is equipped with a signal transmitting module 5, the temperature sensor 4 is used to monitor the temperature inside the pipeline body 1 in real time, and the control unit 6 is used to perform closed-loop control of the temperature inside the pipeline body 1 according to the monitoring result of the temperature sensor 4.

[0017] Furthermore, six heating wires 3 are provided, and the six heating wires 3 are distributed in an array in the circumferential direction of the pipe body 1. A PVC sheath 11 is provided on the outside of the thermally conductive silicone pad 2. The heat generated by the heating wire 3 can be transferred to the thermally conductive silicone pad 2. Since the thermally conductive silicone pad 2 tightly wraps the pipe body 1, the heat generated by the thermally conductive silicone pad 2 is then transferred to the pipe body 1. The PVC sheath 11 plays a good role in waterproofing, moisture-proofing and anti-wear.

[0018] Furthermore, the signal transmitting module 5 is fixedly installed on the surface of the PVC sheath 11, and the input end of the signal transmitting module 5 and the output end of the temperature sensor 4 are electrically connected through the first wiring harness 41. The temperature sensor 4 can monitor the temperature inside the pipe body 1 in real time, and the monitored temperature information can be transmitted to the signal transmitting module 5 in the form of an electrical signal, and the signal transmitting module 5 then transmits the temperature information outward in the form of radio waves.

[0019] Furthermore, the control unit 6 includes a control module 61, a signal receiving module 62 and a main wiring harness 64. The output end of the signal receiving module 62 is electrically connected to the input end of the control module 61 through a second wiring harness 63. One end of the main wiring harness 64 is electrically connected to the output end of the control module 61. One end of the six heating wires 3 are gathered together, and the other end of the main wiring harness 64 is electrically connected to one end of the heating wire 3. After receiving the radio waves emitted by the signal transmitting module 5, the signal receiving module 62 can convert them into electrical signals and transmit them to the control module 61. The control module 61 analyzes the electrical signals. The control module 61 pre-stores the standard temperature value inside the pipeline body 1. The control module 61 can compare the analyzed data with the standard temperature value and then make corresponding instructions.

[0020] The working principle of the utility model: during actual operation, liquid or gas is transported inside the pipeline body 1, the heat generated by the electric heating wire 3 is transferred to the thermally conductive silicone pad 2, and the heat generated by the thermally conductive silicone pad 2 is then transferred to the pipeline body 1, which plays a role in heat preservation of the pipeline body 1. During this process, the temperature sensor 4 monitors the temperature inside the pipeline body 1 in real time, and the monitored temperature information is transmitted to the signal transmitting module 5 in the form of an electrical signal. The signal transmitting module 5 then transmits the temperature information to the outside in the form of radio waves. After receiving the radio wave, the signal receiving module 62 converts it into an electrical signal and transmits it to the control module 61. At this time, the control module 61 analyzes the electrical signal, and the control module 61 pre-stores the standard temperature value inside the pipeline body 1. If the control module 61 finds after analysis that the real-time temperature inside the pipe body 1 is lower than the standard temperature value, the control module 61 increases the current of the main wiring harness 64, the current passing through the heating wire 3 increases, and the heat generated by the heating wire 3 increases, thereby increasing the temperature inside the pipe body 1. If the control module 61 finds after analysis that the real-time temperature inside the pipe body 1 is higher than the standard temperature value, the control module 61 reduces the current of the main wiring harness 64, the current passing through the heating wire 3 decreases, and the heat generated by the heating wire 3 decreases, thereby reducing the temperature inside the pipe body 1. The temperature inside the pipe body 1 can be fed back to the control module 61 in real time, and the control module 61 then makes changes and adjustments to the temperature inside the pipe body 1 in real time, thereby realizing closed-loop regulation and control of the temperature inside the pipe body 1.
