[0002] In the field of offshore oil development, the sewage discharge system of the living building is an important part of the daily operation of the platform. These systems usually use non-metallic pipes to collect and discharge sewage, mainly because non-metallic materials have good corrosion resistance and can adapt to the harsh conditions of high salt and high humidity in the marine environment. However, non-metallic pipes have certain disadvantages in physical properties compared to metal pipes, especially in strength and rigidity. In order to ensure the safety and reliability of the sewage system, it is necessary to conduct a full water static pressure test on the non-metallic pipes to verify the sealing and pressure bearing capacity of the pipe system.

[0003] Traditional plugging methods mainly rely on mechanical plugging devices, which fit tightly to the inner wall of the pipe by physical means to achieve the purpose of temporarily sealing the pipe. However, due to the relatively low strength of non-metallic pipes, traditional plugging devices can easily cause damage to the pipe body during installation and removal, and even cause pipe rupture, increasing the safety risk and maintenance cost of the system. In addition, during the full water static pressure test, the plugging position needs to be precisely adjusted to ensure the sealing effect. However, the traditional plugging method has limited ability to adjust the position during implementation, which often cannot meet actual needs, affecting the accuracy and efficiency of the test.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown,

[0025] A non-metallic pipeline plugging device comprises a pipeline body 1, an end of the pipeline body 1 is sleeved with a sealing sleeve 2, and the inner wall of the pipeline body 1 is provided with a pipeline plugging position adjustable mechanism 3.

[0026] In this embodiment: Under normal circumstances, in order to ensure the safety and reliability of the sewage system, it is necessary to conduct a full water static pressure test on the non-metallic pipe to check the sealing and pressure bearing capacity of the pipe system. The traditional plugging method mainly relies on mechanical plugging devices. These devices fit tightly to the inner wall of the pipe by physical means to achieve the purpose of temporarily closing the pipe. However, due to the relatively low strength of non-metallic pipes, traditional plugging devices are very likely to cause damage to the pipe body 1 during installation and removal, and even cause the pipe to rupture, increasing the safety risk and maintenance cost of the system. In addition, during the full water static pressure test, the plugging position needs to be accurately adjusted to ensure the sealing effect. However, the traditional plugging method has limited ability to adjust the position during implementation, which often cannot meet actual needs, affecting the accuracy and efficiency of the test. Then, by adding an adjustable pipe plugging position mechanism 3, the outer wall of the pipe plugging position can be reinforced and protected, thereby increasing the stability of the pipe. At the same time, the plugging position in the inner wall of the pipe can be adjusted, thereby improving the accuracy and efficiency of the test.

[0027] like Figure 1 - Figure 4 As shown,

[0028] Based on the existing non-metallic pipe plugging device, it can adapt to the physical properties of non-metallic pipes, ensure the plugging effect without causing damage to the pipe, and can flexibly adjust the plugging position to adapt to various situations that may occur in the actual use of the pipe, thereby improving the safety, accuracy and efficiency of the full water static pressure test.

[0029] More specifically:

[0030] In combination with the above content, in order to reinforce and protect the outer wall of the sealing position of the pipeline, thereby increasing the stability of the pipeline, and at the same time adjusting the sealing position in the inner wall of the pipeline, thereby improving the accuracy and efficiency of the test, the inner wall of the pipeline body 1 is provided with a pipeline sealing position adjustable mechanism 3, and the pipeline sealing position adjustable mechanism 3 includes a support plate 31, a guide arm 32, a sliding sleeve 33, a guide sleeve 34, a position adjustment component 35 and a sealing component 36, the support plate 31 is symmetrically fixedly connected to the outer wall of the sealing sleeve 2, one end of the guide arm 32 is fixedly connected to the side wall of the support plate 31, the sliding sleeve 33 is slidably sleeved on the outer wall of the pipeline body 1, the guide sleeve 34 is symmetrically fixedly connected to the outer wall of the sliding sleeve 33, the guide sleeve 34 is slidably sleeved on the outer wall of the guide arm 32, and one end of the position adjustment component 35 passes through the sealing sleeve 2 and is connected to the sealing component 36.

[0033] In this embodiment: in order to improve the strength of the sealing position of the pipeline body 1, the support plate 31 is symmetrically fixedly connected to the outer wall of the sealing sleeve 2, one end of the guide arm 32 is fixedly connected to the side wall of the support plate 31, the sliding sleeve 33 is slidably sleeved on the outer wall of the pipeline body 1, and the guide sleeve 34 is symmetrically fixedly connected to the outer wall of the sliding sleeve 33, and the guide sleeve 34 is slidably sleeved on the outer wall of the guide arm 32, and then according to the position of the plugging component 36, the sliding sleeve 33 can be adjusted to the outer wall of the corresponding pipeline body 1, and then the position of the sliding sleeve 33 can be fixed by the fixing bolt 341, so that when the plugging component 36 blocks the inner wall of the pipeline body 1, the outer wall of the pipeline body 1 can be reinforced by the sliding sleeve 33, and the position of the plugging component 36 can be adjusted by the position adjustment component 35, thereby improving the safety, accuracy and efficiency of the full water static pressure test.

[0034] Specifically, the position adjustment assembly 35 includes a gas pipeline 351, a reinforcement sleeve 352 and a sealing rubber pad 353. One end of the gas pipeline 351 passes through the sealing sleeve 2. The reinforcement sleeve 352 is fixedly sleeved on the outer wall of the gas pipeline 351. The sealing rubber pad 353 is fixedly sleeved on the outer wall of the reinforcement sleeve 352.

[0036] In the present embodiment: in order to adjust the sealing position of the sealing component 36, since one end of the gas pipeline 351 passes through the sealing sleeve 2, the reinforcement sleeve 352 is fixedly sleeved on the outer wall of the gas pipeline 351, and the sealing gasket 353 is fixedly sleeved on the outer wall of the reinforcement sleeve 352, and the outer wall of the sealing gasket 353 is in contact with the inner wall of the pipeline body 1, and then by pulling out the gas pipeline 351, the sealing component 36 can be driven to adjust the position of the inner wall of the pipeline body 1, and at the same time, the positions of the reinforcement sleeve 352 and the sealing gasket 353 can be synchronously driven to make corresponding adjustments, thereby ensuring the sealing effect.

The plugging airbag 363 is fixedly connected between the two fixed sleeves 362, and an air hole is opened in the outer wall of the air injection pipe 361 relative to the plugging airbag 363.

[0038] It should be noted that the inner wall of the blocking airbag 363 described in this embodiment is fixedly connected with a pressure sensor. During the process of the blocking airbag 363 being inflated and expanded, the pressure sensor can monitor the air pressure change in the blocking airbag 363 in real time. By comparing with the preset air pressure range, you can determine whether the expansion degree of the blocking airbag 363 meets expectations. Once the air pressure reaches a specific set value, you can consider that the blocking airbag 363 has reached the desired expansion degree.

[0039] It should be understood that the pressure sensor has built-in electronics for power supply, which can output air pressure signals and wirelessly transmit the signals to a computer to read and record the output of the pressure sensor for subsequent analysis and control.
