Due to changes in flow state and ambient temperature, condensate water will be generated in the pipe, which will gradually accumulate and freeze in a low temperature environment. The gas production pipeline will be frozen and blocked, which will hinder gas transmission.

Two heating rings are arranged inside the U-shaped frame, and an installation groove is provided on the inner wall of the upper wall of the U-shaped frame. The battery is arranged inside the installation groove, and a heating cavity is provided inside the heating ring. A heating rod is arranged inside the heating cavity, and the heating rod is electrically connected to the battery through a power cord. A support frame is fixedly provided on the upper end surface of the U-shaped frame, and a driving clamping assembly is provided on the U-shaped frame through the support frame, so that the natural gas pipeline anti-freezing and blocking device is simple to operate, easy to install and disassemble, and saves time and effort.

[0004] However, the thawing device in the prior art still has certain shortcomings. The size of the heating ring in the prior art is fixed. When the pipeline is large, it may not be able to fully wrap and heat the entire pipeline. When the pipeline is small, the heating ring may be far away from the pipeline wall after wrapping, and it may not be able to effectively and evenly heat the entire pipeline. The adaptability of the heating ring needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 5 , an environmental protection device for preventing pipeline freezing and blocking, comprising a vehicle body 1 and a universal mechanical arm 2, wherein the universal mechanical arm 2 is fixedly connected to the vehicle body 1, and further comprising:

[0031] A connecting plate 3 is fixedly connected to the universal mechanical arm 2;

[0032] The sliding blocks 302 are symmetrically arranged and slidably connected to the connecting plate 3;

[0033] A support rod 3021 is fixedly connected to the slider 302;

[0034] The partition plate 4 is fixedly connected to the support rod 3021;

[0035] The airbag 5 is fixedly connected to the partition 4;

[0036] The first heating part 6 is fixedly connected to the inner wall of the partition 4 .

[0037] An air pump 7 is fixedly connected to the partition 4, a first air pipe 702 is fixedly connected to the air outlet of the air pump 7, a second air pipe 701 is fixedly connected to the air inlet of the air pump 7, and an end of the first air pipe 702 away from the air pump 7 is connected to the airbag 5.

[0038] A slide groove 303 is provided in the connecting plate 3, and the slider 302 is slidably connected in the slide groove 303. The connecting plate 3 is fixedly connected to the electric telescopic rod 301, and a push rod 3011 is fixedly connected to the driving end of the electric telescopic rod 301. The end of the push rod 3011 away from the electric telescopic rod 301 is fixedly connected to the slider 302.

[0039] Reference Figure 1-Figure 5 During use, the vehicle body 1 is controlled to move to the position to be defrosted, and the connecting plate 3 is driven to move by the universal mechanical arm 2. When the pipeline is extended between the two groups of partitions 4, the electric telescopic rod 301 is started, and the electric telescopic rod 301 will drive the push rod 3011 connected to its driving end to move. The movement of the push rod 3011 will push the slider 302 to slide, and the sliding of the slider 302 will drive the partition 4 fixedly connected to it to move, and the partition 4 will approach the pipeline, and the two groups of symmetrically arranged partitions 4 will approach each other. When the partition 4 moves a certain distance, the two groups of partitions 4 will be closely attached, and the air pump 7 can be started at this time. The air pump 7 will extract external gas and input it into the airbag 5. As the gas in the airbag 5 continues to increase, the airbag 5 will swell. When the airbag 5 swells a certain amount, the airbag 5 will be against the pipeline. At this time, the two groups of symmetrical airbags 5 and the two groups of partitions 4 that have been attached will be combined to form a sealed cavity;

[0040] The first heating unit 6 is started, and the first heating unit 6 heats the air in the sealed cavity, heats the pipeline by heating the air, and then thaws the frozen blocks in the pipeline, and heats the hot gas in the sealed cavity, thereby ensuring the uniformity of heating.

[0041] The device is used to heat the pipeline, which can be suitable for pipelines of different sizes. By injecting air into the airbag 5, the inflation degree of the airbag 5 is guaranteed, so that it can be combined with the partition 4 to seal pipelines of different sizes, and then the pipelines of different sizes can be thawed, and the applicability is significantly improved.

[0042] It should be noted that the first heating unit 6 is an electric heating block available on the market.

[0043] It should also be noted that the airbag 5 is a high temperature resistant leather bag available on the market.

[0044] It should be further explained that when the two groups of partitions 4 move relative to each other, the staff can assist in watching and adjusting beside the vehicle body 1 to ensure the alignment accuracy between the partition 4 and the pipeline. At the same time, when the airbag 5 is inflated to clamp the pipeline, the staff can judge whether the airbag 5 is tightly attached to the pipeline by the fit between the airbag 5 and the pipeline.

[0045] It should also be noted that the overall diameter of the partition 4 is larger than the diameter of the pipeline to ensure that the partition 4 can fully wrap the pipeline.

[0046] A filter screen 7011 is fixedly connected to the second gas delivery pipe 701 .

[0047] Reference Figure 5 By setting the filter 7011 in the second air pipe 701, impurities in the extracted air can be effectively filtered, thereby reducing the possibility of impurities entering the airbag 5 through the first air pipe 702.

[0048] A counterweight 101 is fixedly connected to the vehicle body 1 .

[0049] Reference Figure 1 By setting the counterweight 101 on the vehicle body 1, it can be ensured that the vehicle body 1 will not tip over when the universal mechanical arm 2 and the partition 4 are performing the defrosting operation, thereby ensuring the stability of the vehicle body 1 during operation.

[0050] A clamping plate 402 is fixedly connected to the upper partition plate 4 , and a clamping slot 401 is provided on the lower partition plate 4 , and the clamping plate 402 matches the clamping slot 401 .

[0051] Reference Figure 3 , Figure 4 When the upper and lower groups of partitions 4 approach each other, the card plate 402 will simultaneously approach the card slot 401. When the two groups of partitions 4 are against each other, the card plate 402 will be inserted into the card slot 401, thereby ensuring the stability and sealing effect between the two groups of partitions 4 during the defrosting operation.

[0052] Reference Figure 5 A second heating unit 8 is provided on the first gas supply pipe 702.

[0053] It should be noted that the second heating unit 8 can adopt an air heater available on the market, and the specific model can be selected according to usage requirements.

[0054] By means of the second heating unit 8 provided on the first air supply pipe 702, hot air can be input into the air bag 5, so as to ensure that both ends of the partition plate 4 can also heat and defrost the pipes.

[0055] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
