Description

Technical Field

[0001] This utility model relates to the technical field of antifreeze heating devices for gas transmission pipelines, and in particular to an antifreeze heating device for gas transmission pipelines. Background Technology

[0002] Gas pipelines are infrastructure used for transporting gases over long or short distances. However, in low-temperature environments, especially in cold regions or winter, the gas inside the pipeline is prone to freezing, leading to flow obstruction or pipeline damage. Early antifreeze measures included using steam heating and hot water circulation systems to provide heat to the pipeline and prevent the medium inside from freezing. However, these methods are often inefficient and have high maintenance costs. With technological advancements, electric heat tracing has become a more efficient and easily controllable solution. Electric heat tracing tape can be directly attached to the pipeline surface, providing the necessary heat through resistance heating. However, it is usually secured with tape or cable ties, which are prone to loosening and detachment due to thermal expansion and contraction, vibration, or aging during long-term operation, affecting heating efficiency and requiring regular inspection and replacement.

[0003] Therefore, it is necessary to design a gas delivery pipeline antifreeze heating device to solve the above problems. Utility Model Content

[0004] To overcome the drawbacks of relying on tape or cable ties for fixing, this utility model provides a gas conveying pipeline antifreeze heating device.

[0005] The technical implementation scheme of this utility model is as follows: a gas conveying pipeline antifreeze heating device, including gas pipes, flanges, heating belts, clamps, fixing bolts, sleeves, fixers, telescopic springs and controllers. Two gas pipes are fixedly connected to flanges near their center ends. Several heating belts are slidably contacted between the surfaces of the two gas pipes and the two flanges. Clamps are provided on the upper and lower sides between the two gas pipes. Four fixing bolts are threadedly connected between the two clamps. Multiple sleeves are slidably connected to the left and right sides of the two clamps. Each sleeve is slidably connected to a fixer near its center end. A telescopic spring is connected between the corresponding fixer and the sleeve. The fixer is in slidable contact with the heating belt. A controller is fixedly connected to the top of the upper clamp. The controller is electrically connected to the heating belt.

[0006] Furthermore, each fixture has a slot near its center end that corresponds to the heating band.

[0007] Furthermore, it also includes a protective transparent shell, which is fixedly connected to the top of the clamp on the upper side.

[0008] Furthermore, it also includes a temperature sensor and a sensing probe. The temperature sensor is fixedly connected to the top of the upper clamp and is located inside the protective transparent shell. The sensing probe is fixedly connected to the surface of the left air tube near the center end. The sensing probe is electrically connected to the temperature sensor, and the controller is electrically connected to the temperature sensor.

[0009] Furthermore, it also includes a camera, which is fixedly connected to the upper left side of the inner side of the protective transparent shell, and the camera is electrically connected to the controller.

[0010] Furthermore, it also includes a lighting lamp, which is fixedly connected to the lower left side of the inner side of the protective transparent housing, and the lighting lamp is electrically connected to the controller.

[0011] Beneficial effects: 1. This utility model adopts a structure in which the sleeve and the fixing device slide together and a telescopic spring applies a clamping force, so that the fixing device can automatically clamp the heating belt, avoiding the problems of easy loosening, aging, corrosion or scratching of the heating belt insulation layer by traditional tape or metal cable tie fixing.

[0012] 2. This utility model, by equipping a camera and a lighting lamp, can clearly monitor the working status of the heating belt under insufficient light conditions; the image information is collected by the controller and can be transmitted remotely, realizing automatic fault identification, abnormal alarm and remote diagnosis, improving the level of intelligent operation and maintenance, and reducing the cost of manual inspection.

[0013] 3. This utility model uses a fixing device that makes sliding contact with the heating belt. Under the buffering effect of the telescopic spring, the heating belt is allowed to expand and contract freely when the temperature changes, which effectively relieves thermal stress and prevents the heating belt from breaking or delaminating due to repeated expansion and contraction, thus improving the durability of the system.

[0014] 4. Temperature sensors and pipe-mounted induction probes enable real-time and accurate monitoring of pipe surface temperature; the controller automatically adjusts the heating belt power or starts / stops based on feedback signals, forming a closed-loop temperature control system to avoid overheating, achieve on-demand heating, significantly reduce energy consumption, and achieve the purpose of energy saving and freeze protection.

[0023] Example: A gas transmission pipeline antifreeze heating device, such as Figures 1-7 As shown, the device includes an air pipe 1, a flange 2, a heating band 3, a clamp 40, fixing bolts 41, sleeves 42, a retainer 43, a telescopic spring 44, and a controller 53. Two air pipes 1 are fixedly connected to flanges 2 near their center ends. Several heating bands 3 are slidably connected between the surfaces of the two air pipes 1 and the two flanges 2. Clamps 40 are provided on both the upper and lower sides between the two air pipes 1. Four fixing bolts 41 are threadedly connected between the two clamps 40. Multiple sleeves 42 are slidably connected to the left and right sides of the two clamps 40. A retainer 43 is slidably connected to the center end of each sleeve 42. A telescopic spring 44 is connected between the corresponding retainer 43 and the sleeve 42. The retainer 43 is in slidable contact with the heating band 3, and each retainer 43 has a slot corresponding to the heating band 3 near its center end. The controller 53 is fixedly connected to the top of the upper clamp 40 by bolts, and the controller 53 is electrically connected to the heating band 3.

[0024] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a protective transparent shell 50, and the top of the clamp 40 on the upper side is fixedly connected to the protective transparent shell 50 by bolts.

[0025] like Figure 6 and Figure 7As shown, it also includes a temperature sensor 51 and a sensing probe 52. The temperature sensor 51 is fixedly connected to the top of the upper clamp 40 by bolts. The temperature sensor 51 is located inside the protective transparent shell 50. The sensing probe 52 is fixedly connected to the surface of the left air tube 1 near the center end. The sensing probe 52 is electrically connected to the temperature sensor 51. The controller 53 is electrically connected to the temperature sensor 51.

[0026] like Figure 7 As shown, it also includes a camera 54. The camera 54 is fixedly connected to the upper left side of the inner side of the protective transparent shell 50 by bolts. The camera 54 is electrically connected to the controller 53.

[0027] like Figure 7 As shown, it also includes a lighting lamp 55. The lighting lamp 55 is fixedly connected to the lower left side of the inner side of the protective transparent housing 50 by bolts. The lighting lamp 55 is electrically connected to the controller 53.

[0028] At the junction of the two gas pipe sections 1 requiring antifreeze heating, a flange 2 is used to achieve a sealed connection. Two clamps 40 span the outer side of the connection area between the two gas pipe sections 1, and are secured by four threaded bolts 41, ensuring the entire device is firmly installed at the pipe connection point. The heating band 3 is passed through the slot of the clamp 43 on the same parallel line. Under the elastic force of the telescopic spring 44, the clamp 43 presses towards the center, causing it to slide into contact with the surface of the heating band 3, thus stably adhering the heating band 3 to the outer wall of the gas pipe 1. This structure... This design avoids the problems of loosening, aging, and damage to the heating band 3 caused by traditional tape or cable ties, improving installation reliability and service life. It also allows for moderate displacement of the heating band 3 during thermal expansion and contraction, reducing stress damage. Multiple heating bands 3 can be placed according to the pipe size. The sleeve 42 and the fixing device 43 can slide around the clamp 40, allowing multiple heating bands 3 to be evenly distributed along the gas pipe 1 and adhere to the outer surface of the gas pipe 1 and flange 2 for uniform heating of the pipe, preventing gas or moisture from freezing in low-temperature environments. The heating is then controlled by the controller 5. 3. The operation of the heating belt 3 is uniformly started and managed; then the temperature sensor 51 is activated by the controller 53, and the sensing probe 52 is attached to the surface of the gas pipe 1 to monitor the actual temperature of the pipe in real time. The sensing probe 52 transmits the temperature signal to the temperature sensor 51, and then the temperature sensor 51 feeds back to the controller 53. The controller 53 automatically adjusts the operating status of the heating belt 3 according to the preset temperature threshold to achieve intelligent, closed-loop temperature control and achieve the purpose of energy saving and antifreeze. When remote monitoring is required, the camera 54 and the lighting lamp 55 are activated by the controller 53. The lighting lamp 55 can provide supplementary light at night or when there is insufficient light to ensure that the camera 54 can clearly capture the internal working status of the device and the heating belt 3. The camera 54 can monitor in real time whether the heating belt 3 is displaced, damaged or overheated, and transmit the image information to the controller 53 to realize remote operation and maintenance and fault early warning. The protective transparent shell 50 protects the camera 54, the lighting lamp 55, the temperature sensor 51 and the controller 53. At the same time, due to its transparent characteristics, it is convenient for operation and maintenance personnel to directly observe the internal operating status, improving the convenience and safety of maintenance.
