Technical Field
[0001] The utility model relates to the technical field of deicing equipment, in particular to a pipeline deicing device. Background Art
[0002] LNG ships are used to transport liquefied natural gas. The main component of liquefied natural gas is methane. To facilitate transportation, it is usually liquefied by freezing at extremely low temperatures (-165°C) under normal pressure. During the voyage of a ship, it is inevitable to pass through a low-temperature area. However, in a low-temperature environment, water vapor in the air will condense on the surface of the pipeline, forming an ice layer on the outside of the pipeline, exerting additional pressure on the pipeline; greatly increasing the risk of pipeline rupture, posing a safety hazard, so the pipeline needs to be de-iced in a timely manner;
[0003] In the prior art, physical knocking, application of electric deicers, and spreading of chemical deicers are usually used to remove ice accumulated on the outer layer of the pipeline; however, physical knocking will damage the integrity of the pipeline, especially when the pipeline is relatively fragile or already damaged; as for the use of electric deicers or chemical deicers, although these methods will not directly cause physical damage to the pipeline, they require operators to evenly distribute deicing equipment or agents on the entire affected outer surface of the pipeline, and this process is often time-consuming and labor-intensive. Therefore, the present application provides a pipeline deicing device. Utility Model Content
[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a pipeline deicing device, which can rotate around the axis of the pipeline on the outside of the pipeline, perform uniform heat treatment on various positions on the outside of the pipeline, thereby improving the deicing efficiency and being able to be used to de-ice pipelines where ice ridges have formed on the outer wall.
[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Furthermore, two sleeves are provided, and the two sleeves are respectively fixedly mounted on two ends of the swing control handle.
[0008] Furthermore, ice scraping columns which are consistent with the extension direction of the pipeline are respectively arranged on both sides of the groove arm, and the outer side walls of the ice scraping columns are in contact with the outer side wall of the pipeline.
[0009] Furthermore, a telescopic driver is installed on the swing control handle, a collar is fixedly installed on the movable end of the telescopic driver, the collar is rotatably connected to the swing control handle, the fixed end of the telescopic driver is rotatably installed on the positioning seat, and the positioning seat is fixedly connected to the pipeline through a bracket.
[0010] Furthermore, the slot arm is connected to the sleeve via an elastic arm, the elastic arm is detachably fixedly mounted on the sleeve via a fastener, and the slot arm is fixedly connected to a side of the elastic arm close to the pipeline.
[0011] Furthermore, a gap is provided between the end of the slot arm and the sleeve.
[0012] Furthermore, the sleeve is composed of an inner cylinder, an intermediate cylinder and an outer cylinder which are nested and connected to each other. Antifreeze lubricating oil is applied between the inner cylinder and the intermediate cylinder and between the intermediate cylinder and the outer cylinder respectively. The inner cylinder is connected to the pipeline, and the outer cylinder is connected to the elastic arm.
[0013] Regarding the installation of the sleeve of the present application on the pipeline, an optional technical solution is that the sleeve can slide along the axial direction of the pipeline to increase the deicing range.

[0032] Embodiment 1:
[0033] like Figure 1 As shown, this embodiment provides a pipeline deicing device, including a sleeve 12 sleeved on the outside of the pipeline 1, the sleeve 12 is connected to a swing control handle 11, a plurality of slot arms 22 are installed on the sleeve 12, an electric heating wire 23 is arranged in the slot arm 22, the electric heating wire 23 is abutted against the outer wall of the pipeline 1, and two power terminals of the electric heating wire 23 are connected to a power source through wires.
[0034] The swing control handle 11 is provided with a telescopic driver 14, a sleeve is fixedly provided on the movable end of the telescopic driver 14, the sleeve is rotationally connected to the swing control handle 11, the fixed end of the telescopic driver 14 is rotationally installed on a positioning seat, the positioning seat is fixedly connected to the pipeline 1 or the ground through a bracket, and the telescopic driver 14 can use an electric telescopic rod or an electric cylinder.
[0035] When using the pipeline deicing device of this application to de-ice the pipeline:
[0036] The power supply of the electric heating wire 23 is turned on, and the heat generated by the electric heating wire 23 is used to melt the ice layer on the outside of the pipeline 1 to perform deicing operation; at the same time, the telescopic driver 14 is started, so that the ring drives the swing control handle 11 to move, and the control sleeve 12 is controlled to rotate around the outside of the pipeline 1, so that each position on the outside of the pipeline 1 is evenly heat-treated to improve the deicing efficiency;
[0037] During this process, the fixed end of the telescopic driver 14 rotates on the fixed seat 13 , and the collar rotates on the swing control handle 11 .
[0038] Since the ice layer on the outside of pipeline 1 is caused by temperature difference, the present application is applicable to low-temperature environments outside the pipeline, such as heating pipeline systems; it is also applicable to low-temperature environments inside the pipeline, such as LNG truck pipeline systems and LNG ship pipeline systems.
[0039] Since the slot arm 22 is in a strip shape and a single slot arm 22 is smaller than the diameter of the pipeline 1, the slot arm 22 can be installed at a position where the pipeline 1 is not covered with ice, and then rotated by the subsequent sleeve 12 to be used for deicing the pipeline with ice ridges formed on the outer wall.
[0040] like Figure 2 As shown, two sleeves 12 are provided, and the two sleeves 12 are respectively fixedly mounted on the two ends of the swing control handle 11 to increase the movement stability of the slot arm 22 and prevent the end of the slot arm 22 from tilting.
[0041] In order to improve the de-icing efficiency of the equipment, such as Figure 3 As shown, ice scraping columns 24 are respectively arranged on both sides of the groove arm 22 in the same direction as the extension direction of the pipeline 1, so that the outer wall of the ice scraping column 24 abuts against the outer wall of the pipeline 1. During the rotation of the sleeve 12 around the outer side of the pipeline 1, the ice layer attached to the outer side of the pipeline 1 can be scraped to increase the de-icing effect.
[0042] In order to facilitate deicing of ice attached to the outside of the pipeline 1, the slot arm 22 is connected to the sleeve 12 through the elastic arm 21 made of rubber. Specifically, the elastic arm 21 is detachably fixedly installed on the sleeve 12 through a fastener, and the slot arm 22 is fixedly connected to the side of the elastic arm 21 close to the pipeline 1; and a gap is set between the end of the slot arm 22 and the sleeve 12;
[0043] During the elastic deformation of the elastic arm 21, one end of the groove arm 22 can be separated from the outer wall of the pipeline 1 and move between the two sleeves 12, so that the groove arm 22 is buckled on the ice edge on the outer wall of the pipeline 1, so that the electric heating wire 23 is fully in contact with the ice edge, thereby increasing the de-icing effect.
[0044] In this embodiment, the collar is slidably connected to the swing control handle 11, and the sleeve 12 can slide along the axial direction of the pipeline 1 to increase the deicing range.
[0045] Embodiment 2:
[0046] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4 As shown, in this embodiment, the sleeve 12 is composed of an inner cylinder 121, an intermediate cylinder 122 and an outer cylinder 123 which are nested and connected to each other. Antifreeze lubricating oil is applied between the inner cylinder 121 and the intermediate cylinder 122 as well as between the intermediate cylinder 122 and the outer cylinder 123. The inner cylinder 121 is connected to the pipeline 1, and the outer cylinder 123 is connected to the elastic arm 21. Therefore, under low temperature conditions, the sleeve 12 can also rotate freely on the outside of the pipeline 1 to avoid physical damage to the pipeline 1.
[0047] Embodiment three:
[0048] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 As shown, in this embodiment, a plurality of limiting rings are fixedly installed on the pipeline 1, and the sleeve 12 is clamped between the plurality of limiting rings to limit the position of the sleeve 12, so as to perform targeted deicing on the areas of the pipeline 1 that are prone to icing.
