Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to an anti-corrosion wall-penetrating pipe for gas pipelines. Background Art

[0002] Gas pipelines play an indispensable role in households, commerce and industry. Normal temperature gas pipelines are gas pipelines that transport natural gas to buildings, and high-pressure gas pipelines are often used to transport natural gas to industries that require high-pressure gas.

[0003] When installing a gas pipeline, in order to install it in a suitable position, the gas pipeline is usually passed through a wall. Currently, most walls are made of bricks or concrete. These bricks or concrete will corrode the gas pipeline after being in contact with the gas pipeline for a long time. If the gas pipeline is damaged, it will cause gas leakage, endangering the safety of people nearby. In order to solve this technical problem, the utility model proposes an anti-corrosion wall-penetrating pipe for a gas pipeline. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-corrosion wall-penetrating pipe for a gas pipeline, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A corrosion-resistant wall-penetrating pipe for a gas pipeline comprises a gas pipeline body, a protective layer is installed inside the gas pipeline body, a support plate is slidably connected inside the gas pipeline body, a linkage plate is rotatably connected inside the gas pipeline body, a tooth plate is connected inside the linkage plate, a transmission mechanism is arranged inside the gas pipeline body, a cross plate is connected inside the gas pipeline body, a baffle is connected inside the gas pipeline body, a sleeve is connected to the bottom surface of the baffle, and a ball is installed inside the sleeve.

[0007] Preferably, the transmission mechanism comprises a spur gear, an outer surface of the spur gear is meshed with an outer surface of the toothed plate, and a transmission rod is connected to the outer surface of the spur gear.

[0008] Preferably, the outer surface of the transmission rod is rotatably connected to the inside of the transverse plate, and the outer surface of the transmission rod is rotatably connected to the inside of the gas pipeline body.

[0009] Preferably, the outer surface of the transmission rod is connected to bevel gear 1, and the outer surface of bevel gear 1 is meshed with bevel gear 2.

[0010] Preferably, the upper surface of the bevel gear 2 contacts the outer surface of the ball, and the upper surface of the bevel gear 2 is connected with a threaded rod.

[0011] Preferably, the outer surface of the threaded rod is connected to the inner thread of the support plate, and the outer surface of the threaded rod is rotatably connected to the inside of the sleeve.

[0012] Preferably, the protective layer comprises alumina fibers and epoxy resin, and the alumina fibers and epoxy resin are combined together.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, through the cooperation between the protective layer and the support plate and other components, firstly, the protective layer can prevent the gas pipeline body from directly contacting the wall. When installing the pipeline, the pipeline with the protective layer can be installed in the wall. The wall and the gas pipeline body are separated by the protective layer. The support plate can be moved. When the hole opened on the wall is large, the linkage plate can be rotated. The support plate can be moved by the rotation of the linkage plate. The support plate can be brought into contact with the inside of the wall by the movement of the support plate, thereby limiting the position of the gas pipeline body and preventing the gas pipeline body from shaking, thereby avoiding friction between the protective layer and the wall. It is very easy to use and solves the problem of danger to people caused by pipeline corrosion and damage.

[0015] In the utility model, through the cooperation between the cross plate and the ball bearings and other components, firstly, the cross plate can limit the position of the transmission rod, and the transmission rod will pass through the two cross plates. In this way, when the transmission rod rotates, the cross plate will limit the movable position of the transmission rod, thereby reducing the vibration of the transmission rod. When the bevel gear 2 rotates, the threaded rod will rotate with it, and the rotation of the threaded rod will move the support plate, and the baffle will limit the position of the sleeve, and the position of the ball bearings will be limited by the sleeve. In this way, when the support plate rises, the bevel gear 2 will be blocked by the ball bearings, so that the bevel gear 2 cannot rise, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, an anti-corrosion wall-penetrating pipe for a gas pipeline comprises a gas pipeline body 1, a protective layer 2 is installed inside the gas pipeline body 1, a support plate 3 is slidably connected inside the gas pipeline body 1, the protective layer 2 has a high anti-corrosion ability, and can greatly prevent the gas pipeline body 1 from being corroded, the manufacturing material of the support plate 3 is similar to that of the protective layer 2, and also has a high anti-corrosion ability, and the contact points between the support plate 3 and the gas pipeline body 1 and the protective layer 2 are tightly attached, and other objects cannot enter from here.

[0025] The gas pipeline body 1 is internally rotatably connected with a linkage plate 4, and the linkage plate 4 is internally connected with a tooth plate 5. The linkage plate 4 can rotate with the gas pipeline body 1 as the axis. At the same time, the gas pipeline body 1 and the protective layer 2 will limit the position of the linkage plate 4, so that the linkage plate 4 cannot move laterally. The linkage plate 4 will fix the position of the tooth plate 5, so that when the linkage plate 4 rotates, it will also rotate with the tooth plate 5.

[0026] A transmission mechanism 6 is arranged inside the gas pipeline body 1, a transverse plate 7 is connected inside the gas pipeline body 1, and a baffle 8 is connected inside the gas pipeline body 1. The gas pipeline body 1 will fix the position of the transverse plate 7 so that the transverse plate 7 cannot move. The gas pipeline body 1 will fix the position of the baffle 8 so that the baffle 8 cannot move.

[0027] The bottom surface of the baffle 8 is connected to a sleeve 9, and a ball 10 is installed inside the sleeve 9. The baffle 8 fixes the position of the sleeve 9 to increase the stability of the sleeve 9. The ball 10 can roll inside the sleeve 9 but cannot be directly pulled out of the sleeve 9.

[0028] The transmission mechanism 6 includes a spur gear 601, the outer surface of which is meshed with the outer surface of the toothed plate 5. The outer surface of the spur gear 601 is connected to a transmission rod 602, which can rotate the spur gear 601 when the toothed plate 5 rotates. The rotation of the toothed plate 5 can rotate all the spur gears 601. The transmission rod 602 can fix the position of the spur gear 601, and can rotate with the transmission rod 602 when the spur gear 601 rotates.

[0029] The outer surface of the transmission rod 602 is connected to the inner rotation of the cross plate 7, and the outer surface of the transmission rod 602 is connected to the inner rotation of the gas pipeline body 1. The position of the transmission rod 602 is limited by the cross plate 7 to reduce the vibration generated when the transmission rod 602 rotates. The gas pipeline body 1 will limit the position of the transmission rod 602 and prevent the transmission rod 602 from moving laterally.

[0030] The outer surface of the transmission rod 602 is connected to bevel gear one 603, and the outer surface of bevel gear one 603 is meshed with bevel gear two 604. The transmission rod 602 will fix the position of bevel gear one 603. Two bevel gears one 603 are fixedly sleeved on the surface of each transmission rod 602. When the transmission rod 602 rotates, all the bevel gears one 603 on the surface will rotate with it. Each bevel gear one 603 is meshed with a bevel gear two 604. When the bevel gear one 603 rotates, it will also rotate with the bevel gear two 604.

[0031] The upper surface of bevel gear 2 604 contacts the outer surface of ball 10. The upper surface of bevel gear 2 604 is connected with threaded rod 605. Ball 10 is used to limit the position of bevel gear 2 604 so that bevel gear 2 604 cannot move upward. When bevel gear 2 604 rotates, ball 10 can be brought along to rotate. Ball 10 can be used to reduce the friction force when bevel gear 2 604 rotates, so that the service life of bevel gear 2 604 is longer. Bevel gear 2 604 will fix the position of threaded rod 605 and will bring threaded rod 605 to rotate when bevel gear 2 604 rotates.

[0032] The outer surface of the threaded rod 605 is connected to the internal thread of the support plate 3, and the outer surface of the threaded rod 605 is rotatably connected to the inside of the sleeve 9. When the threaded rod 605 rotates, the support plate 3 can be moved. The position of the support plate 3 is controlled by the number of rotations of the threaded rod 605, making the movement of the support plate 3 more controllable. The position of the threaded rod 605 is limited by the sleeve 9, thereby reducing the vibration generated when the threaded rod 605 rotates.

[0033] The protective layer 2 includes alumina fiber 201 and epoxy resin 202. The alumina fiber 201 and epoxy resin 202 are combined together. Adding alumina fiber 201 filler to the epoxy resin 202 can significantly improve the material's mechanical properties, wear resistance, thermal conductivity and electrical insulation properties, while the epoxy resin 202 itself has good corrosion resistance. The combination of the two can better protect the gas pipeline body 1.

[0034] Working principle: When using the device, first, you need to put the gas pipeline body 1 with the protective layer 2 into the hole opened in the wall. If you find that the hole is too large, you can rotate the connecting plate 4. The rotation of the connecting plate 4 will cause the tooth plate 5 to rotate, and the rotation of the tooth plate 5 will cause the spur gear 601 to rotate. The rotation of the spur gear 601 will cause the transmission rod 602 to rotate. The rotation of the transmission rod 602 will drive the bevel gear 1 603 to rotate. The rotation of the bevel gear 1 603 will cause the bevel gear 2 604 to rotate. The rotation of the bevel gear 2 604 will cause the threaded rod 605 to rotate. The support plate 3 is moved by the rotation of the threaded rod 605. By moving the support plate 3 to a position in close contact with the inner wall of the wall hole, the position is restricted, thereby completing the installation of the pipeline.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
