Description
Technical Field
[0001] The utility model relates to the technical field of thermal insulation steel pipes, in particular to a thermal insulation steel pipe. Background Art
[0002] Steel pipes have hollow cross-sections, and their length is much greater than their diameter or circumference. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, they are divided into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.
[0003] However, when steel pipes are used to transport some liquid substances in winter, the extremely cold weather often causes the liquid in the pipe to freeze and become blocked, making it impossible to carry out the transportation task. Therefore, a steel pipe that can keep warm is needed.
[0004] Therefore, the utility model provides a thermal insulation steel pipe to solve the above problems. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides an insulated steel pipe to solve the above-mentioned problems. The steel pipe body is wrapped by a rock wool board. Since the rock wool board has a good thermal insulation effect, the outside temperature change cannot effectively affect its interior, and the heat inside the steel pipe is not easy to dissipate. If the outside temperature continues to drop, the heating block can be turned on to generate heat, and the heating blocks are distributed around the steel pipe body to make the steel pipe body evenly heated; by turning the rotating ring, the screw can be driven to rotate, and the screw can then move downward. Under the limiting action of the limit rod, the arc clamping block cannot rotate and can only move vertically downward to clamp the steel pipe body to ensure that the entire insulation component will not slide at will.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an insulated steel pipe, comprising a steel pipe main body, an insulation component is provided on the outer wall of the steel pipe main body, and an auxiliary component is provided on one end of the insulation component; the insulation component comprises an outer protective cylinder, the inner wall of the outer protective cylinder is fixedly connected with a rock wool board, the inner wall of the outer protective cylinder is also fixedly connected with a connecting block, one end of the connecting block is fixedly connected with a heating block, and the outer wall of the steel pipe main body is in contact with one side of the heating block and is movably connected.
[0007] Furthermore, the auxiliary component includes a reinforcement block, which is inserted into one end of the outer protective cylinder. The outer wall of the outer protective cylinder is fixedly connected with a nut block, and the nut block is connected to the internal thread of the outer protective cylinder with a bolt.
[0008] By adopting the above technical solution, the reinforcement block is fixed to protect the thermal insulation component.
[0009] Furthermore, the inner thread of the reinforcement block is connected to a screw rod, and one end of the screw rod is rotatably connected to an arc-shaped clamping block.
[0010] By adopting the above technical solution, the steel pipe body is clamped to generate friction to prevent the entire insulation component from sliding randomly.
[0011] Furthermore, the outer wall of the arc-shaped clamping block is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the inside of the reinforcement block.
[0012] The above technical solution is used to limit the rotation of the arc-shaped clamping block.
[0013] Furthermore, one end of the screw is fixedly connected with a swivel.
[0014] The above technical solution is adopted to facilitate the rotation of the screw.
[0015] Furthermore, the limiting rod, the reinforcing block, the outer protective cylinder and the arc-shaped clamping block are made of engineering plastics.
[0016] By adopting the above technical solutions, engineering plastics are a new type of material with high strength, high toughness and high durability that can replace traditional industrial materials. With the continuous development of technology, the strength of engineering plastics has become closer and closer to that of steel. For example, in terms of UV resistance, wear resistance, corrosion resistance, etc., some special engineering plastics have reached the strength of steel. At the same time, engineering plastics are also light in weight and easy to process, which can effectively reduce the overall weight of the device.
[0017] Beneficial Effects
[0018] The utility model provides a heat-insulating steel pipe. Compared with the prior art, it has the following beneficial effects:
[0019] 1. The insulated steel pipe is wrapped with a rock wool board. Since the rock wool board has good thermal insulation effect, the external temperature change cannot effectively affect its interior, and the heat inside the steel pipe is not easy to dissipate. If the external temperature continues to drop, the heating block can be turned on to generate heat, and the heating blocks are distributed around the steel pipe body to make the steel pipe body evenly heated.
[0020] 2. The insulated steel pipe can drive the screw to rotate by twisting the rotating ring, and the screw can then move downward. Under the restriction of the limit rod, the arc-shaped clamping block cannot rotate and can only move vertically downward to clamp the steel pipe body to ensure that the entire insulation assembly will not slide at will.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0031] The present application is further described in detail below through drawings and examples.
[0032] Reference Figures 1 to 7 The embodiment of the present application provides an insulated steel pipe, including a steel pipe body 1, an insulation component 2 is provided on the outer wall of the steel pipe body 1, and an auxiliary component 3 is provided at one end of the insulation component 2; the insulation component 2 includes an outer protective cylinder 21, and the inner wall of the outer protective cylinder 21 is fixedly connected with a rock wool board 22, and the inner wall of the outer protective cylinder 21 is also fixedly connected with a connecting block 23, and one end of the connecting block 23 is fixedly connected with a heating block 24, and the outer wall of the steel pipe body 1 is in contact with one side of the heating block 24 and is movably connected.
[0033] During specific implementation: the steel pipe body 1 is wrapped by the rock wool board 22. Since the rock wool board 22 has good thermal insulation effect, the external temperature change cannot effectively affect its interior, and the heat inside the steel pipe is not easy to dissipate. If the external temperature continues to drop, the heating block 24 can be turned on to generate heat, and the heating blocks 24 are distributed around the steel pipe body 1 to make the steel pipe body 1 evenly heated (the rock wool board 22 has excellent thermal insulation performance, fire resistance, sound absorption performance and corrosion resistance).
[0034] Reference Figures 1 to 7 In one aspect of the present embodiment, the auxiliary component 3 includes a reinforcement block 31, which is inserted into one end of the outer protection cylinder 21. A nut block 32 is fixedly connected to the outer wall of the outer protection cylinder 21, and a bolt 33 is connected to the inner thread of the nut block 32 and the outer protection cylinder 21. A screw rod 34 is connected to the inner thread of the reinforcement block 31, and an arc-shaped clamping block 37 is rotatably connected to one end of the screw rod 34. A limit rod 36 is fixedly connected to the outer wall of the arc-shaped clamping block 37, and the limit rod 36 is slidably connected to the inner part of the reinforcement block 31. A swivel 35 is fixedly connected to one end of the screw rod 34. The limit rod 36, the reinforcement block 31, the outer protection cylinder 21 and the arc-shaped clamping block 37 are made of engineering plastics.
[0035] During specific implementation: by twisting the rotating ring 35, the screw 34 can be driven to rotate, and the screw 34 can then move downward. Under the limiting effect of the limit rod 36, the arc clamping block 37 cannot rotate and can only move vertically downward to clamp the steel pipe body 1 to ensure that the entire insulation component 2 does not slide at will (engineering plastics are a new type of material with high strength, high toughness, and high durability, which can replace traditional industrial materials).
[0036] All electrical equipment in this solution are powered by an external power supply.
[0037] Working principle: The steel pipe body 1 is wrapped by the rock wool board 22. Since the rock wool board 22 has good thermal insulation effect, the external temperature change cannot effectively affect its interior, and the heat inside the steel pipe is not easy to dissipate. If the external temperature continues to drop, the heating block 24 can be turned on to generate heat, and the heating blocks 24 are distributed around the steel pipe body 1 to make the steel pipe body 1 evenly heated. By turning the rotating ring 35, the screw 34 can be driven to rotate, and the screw 34 can then move downward. Under the limiting action of the limit rod 36, the arc clamping block 37 cannot rotate and can only move vertically downward to clamp the steel pipe body 1 to ensure that the entire insulation component 2 will not slide at will.
