Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline pressure holding test technology, and in particular relates to a gas pipeline pressure holding test device. Background Technology

[0002] With the widespread use of urban gas, the safety of gas pipelines has become particularly important. Any leaks or malfunctions in the pipeline system can lead to serious safety accidents and even threaten personal and public safety. Therefore, establishing an intelligent pressure testing device for regular pressure testing and monitoring of gas pipelines is an important means to ensure the safe operation of the gas system.

[0003] Currently, with the increasing scale of urban gas pipelines, several operational bottlenecks have emerged: the density of gas pipeline projects within the same area is increasing, and the scale of gas pipelines is becoming increasingly large. Traditional manual inspections are inefficient, costly, and time-consuming, failing to detect pipeline problems in a timely manner. Therefore, we propose a gas pipeline pressure-holding testing device. Utility Model Content

[0004] The purpose of this invention is to provide a gas pipeline pressure holding test device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a gas pipeline pressure holding test device, comprising:

[0006] The test chamber has a protective cover rotatably mounted on one side, a lifting handle rotatably mounted on the top, and a horizontal lifting handle rotatably mounted on the other side. From left to right, the top of the test chamber is provided with an antenna, a pressure transmitter, a power switch, a solenoid valve interface, and a charging interface. A sliding groove is provided inside the test chamber, and a drag handle is slidably mounted in the sliding groove. The bottom of the test chamber has symmetrically provided rotating grooves, and rollers are rotatably mounted in the rotating grooves.

[0007] A limiting component, located inside the test chamber, is used to limit the drag handle;

[0008] A lithium battery is fixedly installed inside the test chamber. An installation plate is fixedly installed inside the protective cover. A data processing terminal and a power management module are fixedly installed on one side of the installation plate.

[0009] In this technical solution, when the test box needs to be moved during use, personnel can first release the drag handle through the limiting component. Personnel can then pull the drag handle out of the sliding groove and pull it to a suitable length according to their own height. Subsequently, the limiting component can limit the drag handle, and then personnel can pull the test box through the drag handle. With the action of the two rollers rotating, personnel can easily move the test box by pulling the drag handle. This equipment can realize one-to-many monitoring. When there is a need for maintenance of gas pipelines, it can facilitate personnel to quickly transport the equipment to the site. After the monitoring is completed, it can be transported to the next piece of equipment for testing, ensuring that personnel can easily move the entire device.

[0010] This device supports automatic switching between multiple scenarios. When the electrically controlled valve is open, the device monitors the operating parameters of the pressure regulator, preprocesses and analyzes the collected data, and intelligently analyzes the health of the pressure regulator through the powerful "pressure regulator health model" of the cloud platform. During non-user gas usage periods, the electrically controlled valve automatically closes according to the preset time. The device collects the pipeline pressure data from the pressure regulator outlet to the user end. By collecting the pressure data of the sealed pipeline and combining it with the "pipeline health model" for intelligent analysis, it can determine whether there is any damage or leakage in the pipeline and the condition of the leak.

[0011] If the system detects gas consumption during the pressure holding test, the adaptive interruption mechanism will be automatically triggered. At this time, the system will quickly terminate the ongoing pressure holding test and immediately restore normal gas supply. Through the automatic control function of the solenoid valve, combined with the system's built-in intelligent logic judgment, gas supply continuity is achieved. During the automatic termination of the test, the system ensures seamless connection between each stage; from test termination to gas supply restoration, the entire process is fast and stable, ensuring that users' gas supply is not affected.

[0012] In the above technical solution, the limiting component further includes:

[0013] A sliding groove is provided inside the test chamber and located on one side of the sliding groove. A limit block is slidably installed inside the sliding groove. Several limit holes are provided on one side of the drag handle. One end of the limit block passes through one side of the sliding groove and extends into one of the limit holes. A pull rod is fixedly installed at the other end of the limit block and located inside the sliding groove. One end of the pull rod passes through the other side of the sliding groove and extends to the outside. A spring is sleeved on the pull rod and located inside the sliding groove.

[0014] In this technical solution, during use, when the test box needs to be moved, personnel can first pull the lever. The movement of the lever will cause the limit block to move, and the movement of the limit block will compress the spring until one end of the limit block moves out of one of the limit holes. At this time, the limit block can release the drag handle, and personnel can pull the drag handle out of the sliding groove. Personnel can pull the drag handle to a suitable length according to their own height, and then release the lever. At this time, under the action of the spring rebound force, the spring will compress the limit block to move until one end of the limit block is inserted into the corresponding limit hole, thereby limiting the drag handle. Then, personnel can pull the test box by dragging the handle. With the action of the two rollers rotating, personnel can easily pull the test box to move. This equipment can realize one-to-many monitoring. When there is a need for maintenance of gas pipelines, it can facilitate personnel to quickly transport the equipment to the site. After the monitoring is completed, it can be transported to the next piece of equipment for testing, ensuring that personnel can easily move the entire device.

[0015] In the above technical solution, one end of the limiting block is inserted into the limiting hole, the pull rod is slidably connected to the slide groove and the test box, and the two ends of the spring are respectively tightly welded to the inner wall of the limiting block and the slide groove.

[0016] In this technical solution, it is ensured that one end of the limiting block can be inserted into the limiting hole, ensuring that the pull rod can slide normally in the slide groove and the test box, and ensuring the structural stability of the spring.

[0017] In the above technical solution, furthermore, the plurality of the limiting holes are distributed vertically at equal intervals.

[0018] In this technical solution, the adjustable length range of the drag handle is ensured to be wider.

[0019] Furthermore, the above technical solution also includes:

[0020] Two quick-release latches are rotatably mounted on the other side of the test chamber, with one end of each quick-release latch engaging with the protective cover.

[0021] In this technical solution, personnel can unlock and open the protective cover using two quick-release latches.

[0022] In the above technical solution, the lithium battery is further electrically connected to the antenna, pressure transmitter, power switch, solenoid valve interface, charging interface, data processing terminal and power management module.

[0023] In this technical solution, the structural stability of the lithium battery, antenna, pressure transmitter, power switch, solenoid valve interface, charging interface, data processing terminal, and power management module is ensured.

[0024] Furthermore, in the above technical solution, the drag handle has a U-shaped structure.

[0025] In this technical solution, the structural stability of the drag handle is ensured.

[0026] The beneficial effects of this utility model are:

[0027] This gas pipeline pressure holding test device, through the setting of limit components, can achieve one-to-many monitoring through the cooperation of the limit components, drag handle, test box and sliding groove. When there is a need for maintenance of gas pipelines, it can facilitate the quick transportation of the equipment to the site. After the monitoring is completed, it can be transported to the next equipment for testing, ensuring that the entire device can be moved by personnel. Attached Figure Description
