Description

The utility model refers to devices used in the gas industry, in particular, it is intended for instrumental determination of the fact of the passage of an in-line device (hereinafter referred to as VTU) in sections of the main gas pipeline (hereinafter referred to as MG), not equipped with stationary alarms, during in-line flaw detection.

The process of examining the state of the internal cavity of the main gas pipeline or gas pipeline-branch provides for the instrumental establishment of the fact that the VTU has passed the reference points. The MG is equipped with stationary alarms, transmitting information about the passage of the VTU at the points specified by the project in automatic mode. If it becomes necessary to establish the fact of the passage of the VTU at randomly specified points, a portable signaling device is used.

Known portable signaling device of the passage of the WTO REPER-ZV (development of LLC "Scientific and Technical Enterprise Engineering and Production Center") [1]. The signaling device consists of two sensors, sensitive to changes in the magnetic field, and a reception and registration unit. The sensors are placed on the ground surface along the pipeline axis and are connected by a cable to the receiving and recording unit. The fact that the VTU passes the reference point is recorded by magnetic sensors, while the receiving and recording unit generates a sound signal.

The disadvantages of this device in relation to a useful model are significant dimensions (320 × 320 × 400 mm), weight (22 kg), as well as the recharge time of batteries (14 hours). Delivery of the signaling device to the place of work is carried out by road, in case of impossibility of passage, delivery of the signaling device over a long distance is difficult. When the indicator battery is discharged, recharging is required, which can be carried out only from a stationary power supply.

The task of the utility model is to facilitate the process of extracting the element base of the portable signaling device of the passage of the VTU.

EFFECT: prompt replacement of the signal device power supply in the field.

The task is being solved, and the technical result is achieved by developing a portable signaling device powered by replaceable storage batteries with the ability to quickly replace them.

The declared portable device for signaling the passage of the VTU is explained using:

fig. 1 is a schematic diagram of the arrangement of device elements; fig. 2 is an electrical schematic diagram of the device.

The device consists of a Nano CH340 controller (4), a three-axis magnetic field sensor GY-271 (2), a block of LEDs (6) and a switch (8). The device is powered through the USB port of the controller (4) from a 6 V DC source (3), which can be a rechargeable battery of four cells of the common AAA format. The device is mounted in a hermetically sealed enclosure (5) of circular cross-section on a substrate (7) to facilitate the process of removing the element base from the enclosure and is equipped with a lance (1) for installation in the ground.

The device operates as follows. A portable signaling device by immersing the peak (1) in the ground is installed on the surface of the gas pipeline embankment in the section through which the VTU is expected to pass, and is turned on using a switch (8). The turn-on signal is the green glow of the LED block (6), which is visible through the housing (5). When the HTU containing metal parts passes, the magnetic field changes in the gas pipeline section. This change at the point of installation of the device is registered by the three-axis magnetic field sensor (2) of the device and is transmitted to the controller (4). The controller (4) processes the received data on the change in the magnetic field value with respect to time. When the signal level of the magnitude of the change in the magnetic field corresponds to the value specified in the controller configuration, an output signal is issued. In this version of the device, the output signal (the fact of establishing the passage of the VTU) is a change in the glow color of the LED block (6) on the signaling device from green to red.
