Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline protection, and particularly relates to a temporary protection monitoring device for gas pipelines. Background Technique

[0002] In order to protect buried gas pipelines from construction damage, laws and regulations clearly require that when earthwork construction is carried out within 5 meters around the gas pipeline, the pipeline needs to be explored, generally by excavating to see the gas pipeline to determine, so as to accurately identify the position of the underground gas pipeline. When there is a situation where a new project crosses or runs parallel to the pipeline, construction operations need to be carried out under the condition of exposed pipes. However, there is currently no effective measure to protect the exposed gas pipeline after excavation; the defects of the current practice are as follows:

[0003] 1. Temporarily wrapping with cloth or soft substances can only avoid direct sunlight and cannot prevent collisions. Moreover, there is no obvious warning sign to inform what the wrapped object is.

[0004] 2. Temporarily wrapping with wooden boards has a low matching degree, is difficult to fix, is easy to scratch the pipeline, and has a poor protection effect. Moreover, there is no obvious warning sign to inform what the wrapped object is.

[0005] 3. After temporary wrapping, it is impossible to monitor whether the pipeline is collided or damaged during construction, and potential hazards cannot be eliminated in time. Content of the Utility Model

[0006] To solve the above problems, the utility model aims to provide a temporary protection monitoring device for gas pipelines. The buffer mechanism and two semi-cylinders cooperate with the protective sleeve to effectively protect the internal gas pipeline.

[0021] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] Embodiment 1

[0023] See Figures 1-3 : A temporary protection monitoring device for a gas pipeline, including two semi-cylindrical bodies 1. The two semi-cylindrical bodies 1 are spliced together through a first buckle 2 and installed and fixed on the gas pipeline 3. A number of buffer mechanisms 4 are installed on the circumferential outer walls of the two semi-cylindrical bodies 1, and the telescopic ends of the buffer mechanisms 4 are abutted against a protective sleeve 5.

[0024] In this embodiment, the protective sleeve cooperates with the buffer mechanism and the two semi-cylindrical bodies to effectively protect the internal gas pipeline. The internal buffer mechanism can better resolve the impact force and reduce the damage to the gas pipeline, preventing the internal gas pipeline from being knocked and damaged during construction.

[0025] In a specific example, the protective sleeve 5 is composed of two semi-cylindrical sleeves, and the two semi-cylindrical sleeves are spliced together through a second buckle 6 to form a whole.

[0026] The protective sleeve in this embodiment is also composed of two semi-cylindrical sleeves, which are spliced together through a second buckle, facilitating installation and disassembly.

[0027] In a specific example, the buffer mechanism 4 includes a buffer cylinder body 401. A spring 402 is installed inside the buffer cylinder body 401. The end of the spring 402 is connected to a transmission rod 403. The transmission rod 403 is movably installed at the end of the buffer cylinder body 401 through a plug cap 404, and the transmission rod 403 abuts against the inner wall of the protective sleeve 5.

[0028] In a specific example, it further includes a pressure sensor 405 and a signal transmitter 406. The pressure sensor 405 is installed inside the buffer cylinder body 401 and connected to the bottom of the spring 402. The signal transmitter 406 is installed on the outer walls of the two semi-cylindrical bodies 1, and the pressure sensor 405 is electrically connected to the signal transmitter 406.

[0029] In this embodiment, the pressure sensor can monitor whether the protective sleeve is impacted by external force, and can send the impact information to the supervisors through the signal transmitter, playing an alarm role.

[0030] In a specific example, it further includes a rubber pad 7. The rubber pad 7 is installed between the two semi-cylindrical bodies 1 and the gas pipeline 3 for buffering. The rubber pad 7 is composed of two semi-cylindrical pads, and the two semi-cylindrical pads are spliced together through a third buckle 8 to form a whole and wrap around the gas pipeline 3.

[0031] In this embodiment, the rubber pad can enhance the buffering protection effect to ensure the safety of the gas pipeline during construction.

[0032] In a specific example, warning signs are provided on the outer surface of the protective sleeve 5.

[0033] On the outer surface of the protective sleeve in this embodiment, warning signs can be added according to the information of the protected pipeline.

[0034] In a specific example, grooves corresponding to and matching the telescopic ends of the buffer mechanism 4 are provided on the inner wall of the protective sleeve 5.

[0035] In this embodiment, by providing grooves corresponding to and matching the telescopic ends of the buffer mechanism on the inner wall of the protective sleeve, it is possible to prevent the buffer mechanism from being displaced when being impacted, thereby improving the buffering effect.

[0036] In a specific example, at every set distance, four buffer mechanisms 4 are evenly arranged circumferentially on the outer walls of the two semi-cylinders 1.

[0037] In this embodiment, according to the length of the gas pipeline, at every set distance, four buffer mechanisms can be evenly arranged circumferentially on the outer walls of the two semi-cylinders to improve the buffering protection effect of the gas pipeline.

[0038] The working principle of this embodiment: When an external force impacts the protective sleeve, the impact force presses on the spring through the transmission rod, playing a buffering role, and triggering the pressure sensor to output a signal to the signal transmitter and transmit the signal to the supervisor, playing an alarm role. The impact force is then transmitted to the main semi-cylinder through the spring. Since the semi-cylinder and the rubber pad are completely attached to the surface of the gas pipeline, the impact force can be evenly distributed, playing a very good protective role.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
