Description

A mechanical signaling device for the passage of continuous shells into the chamber for their reception from the main pipeline

The utility model relates to elements of equipment used in the operation of trunk pipelines, and can be used, for example, in the oil and gas industry for equipping stationary or temporary placement chambers for receiving treatment, diagnostic, and other continuous flow shells from the main pipeline.

Known signaling devices for the passage of in-tube objects (see, for example, RF patent No. 2030678, auth. Certificate of the USSR No. 1629684,), in which acoustic radiation at ultrasonic frequencies above 100 kHz, arising from friction, collision against the wall, is used to record the passage of the in-pipe object. pipe and throttling fluid through the gap between the object and the pipeline. These signaling devices consist of a receiving device containing piezoelectric transducers, an amplifier, a bandpass filter, a signal processing unit, and a unit for connecting to a linear telemechanics, providing dispatch communication between the operator and the control point.

The disadvantage of these signaling devices is their applicability only for oil pipelines, while the search for a stuck in-pipe object causes considerable difficulties. In addition, there have been cases of false alarms of such signaling devices during rain, for this reason they have not found widespread use.

Also known are signaling devices for passing treatment or diagnostic objects through a pipeline equipped with signal sources in the form of a magnet holder with permanent magnets (see ed. Certificate of the USSR No. 1285261) or in the form of a transmitter (transmitter) emitting

low-frequency electromagnetic waves (see, for example, the RF patent for utility model No. 51235 or the Poisk-MP signaling device, technical description of the Pipeline Systems Service Center, Ufa, 2006).

These signaling devices consist of a receiving device containing magnetic induction antennas, an amplifier, a bandpass filter, a signal processing unit, and a connection block to a linear telemechanics, providing dispatch communication between the operator and the control point.

A significant drawback of these devices is the low noise immunity due to the use of amplifiers with a high gain, which leads to false positives when magneto-induction antennas are exposed to extraneous pulsed electromagnetic signals, pipeline vibrations from passing vehicles, and the like.

Another disadvantage of these devices is the often observed practice pass registration of the passage of the in-pipe object due to the reduced radiation power of the transmitter when its supply batteries are discharged, caused by long passage through an extended pipeline.

Also, the designs of the above devices suggest the need for their connection to a linear telemechanics system, as well as the presence of an electric current source or electromagnetic radiation.

Known adopted as a prototype mechanical indicator of the passage of continuous shells through the pipeline, comprising a housing, a connecting rod-pusher, a lower lever, a spring-loaded lever and a flag.

The principle of operation of such a signaling device is that its body with all other elements located in it is mounted on a pipeline, into which a lower arm protrudes vertically, moving vertically under the influence of a flow projectile passing through the pipeline.

One of the disadvantages of such an alarm is a violation of the integrity of the pipeline during its installation (insert). However, due to its high reliability, ease of maintenance, suitability for fixing the passage of an in-line projectile of any type without special alteration through pipelines of various diameters, and safety for service personnel, such mechanical signaling devices are most widely used (see, for example, Valueva N.A., Lavrentiev M. A., Lvov SL, Signaling device for the passage of treatment and separation devices along main pipelines / Problems of automated control of oil industry facilities. iev: Publishing House of the KIA, 1989. - P. 54-58).

Moreover, in the context of the problem solved by the claimed utility model, the main disadvantage of the mechanical signaling device adopted as a prototype is that, due to the different lengths of the flow projectiles, it does not allow with sufficient accuracy to record the complete passage of such shells into the chamber for receiving flow devices from the main a pipeline having an eccentric adapter installed between the camera body for receiving and a linear pipe equipped with shutoff valves, for example , with a ball valve, since it involves installation (tie-in) precisely on the main pipeline directly in front of the linear pipe or on the linear pipe itself.

The objective of the utility model is to create a mechanical signaling device for the passage of continuous shells into the chamber for their reception from the main pipeline, leveling the lack of a prototype.

The technical result consists in providing the possibility of realizing the purpose of the utility model, as well as in ensuring the accuracy of fixing the complete passage of continuous shells of various lengths into the chamber for receiving continuous shells from the main pipeline.

The task and the specified technical result in a mechanical signaling device for the passage of continuous projectiles into the chamber for their reception from the main pipeline, including the housing, the connecting rod, the lower arm, the spring-loaded lever and the flag, respectively, is solved and achieved by the fact that it is made with the possibility of installation on the housing chambers for receiving in-line projectiles from the main pipeline, for which it additionally contains two coaxially located pipes installed inside the camera body for receiving in-line shells from the main pipeline in such a way that, with the translational movement of the inner pipe toward the lower arm, provides the possibility of influencing the lower arm, the outer pipe is equipped with brackets for its installation inside the camera body for receiving by welding, an extended groove is made on the outer pipe, which ensures translational movement the inner pipe towards the lower arm the possibility of curvilinear movement along the specified groove of the finger, mounted on the inner pipe, with a deviation from the initial position of the finger is not more than 90 °, while the finger is fixed with the possibility of its dismantling in one of the landing holes made in the body of the inner pipe, and is equipped with a spherical head.

The mechanical signaling device for the passage of continuous projectiles into the chamber for receiving them from the main pipeline is also characterized in that the lower lever is exposed to an arc-shaped bracket located on the end of the inner pipe directed towards the lower lever with the possibility of one of its sides resting on the end of the outer pipe.

The essence of a mechanical signaling device for the passage of continuous projectiles into the chamber for their reception from the main pipeline is illustrated by graphic materials, where in FIG. 1 schematically shows the placement of the indicated detector on the camera body for receiving in-line shells, FIG. 2 - cutout A in FIG. 1, in FIG. 3 - cutout B in FIG. one,

in FIG. 4 - coaxially arranged pipes with an extended groove on the outer pipe, in FIG. 5 is a view A in FIG. four.

The mechanical signaling device for the flow of shells into the chamber for receiving them from the main pipeline includes a housing 1, a connecting rod-pusher 2, a lower lever 3, a spring-loaded lever 4 and a flag 5.

Along with these elements, the specified mechanism additionally contains two coaxially located pipes, inner 6 and outer 7, installed inside the camera body for receiving in-line shells from the main pipeline so that, with the forward movement of the inner pipe 6 towards the lower arm 3, it is possible to act on the lower arm 3 by means of, for example, an arcuate bracket 8, located on the end of the inner pipe 6 directed towards the lower lever 3 with the possibility of abutment of one of its x of the sides at the end of the outer pipe 7. Moreover, in the position where the arcuate bracket 8 abuts one of its sides against the end of the outer pipe 7, the distance between the opposite side of the arcuate bracket 8 and the lower arm 3 is not more than 10-15 mm.

The outer pipe 7 is provided with brackets 9 for installation inside the camera body 10 for receiving by welding.

An extended groove 11 is made on the outer pipe 7, which allows for the forward movement of the inner pipe 6 towards the lower arm 3 to allow a curved motion along the extended groove 11 of the finger 12, mounted on the inner pipe 6, with a deviation of not more than 90 ° from the original position of the finger 12.

The finger 12 is fixed with the possibility of its dismantling in one of the landing holes 13, made with a given step, for example, 100 mm in the body of the inner pipe 6 and the number of which is determined by the overall dimensions of the housing 10 of the receiving chamber, a linear pipe 14 with shutoff valves 15, an adapter 16 and a continuous projectile (not shown in FIG.).

The finger 12 is provided with a spherical head 17.

The inner pipe 6 is provided with a handle 18.

The end of the outer pipe 7, directed towards the adapter 16, is beveled to allow tight coupling with the inner surface of the adapter 16.

Mounted mechanical signaling the passage of continuous shells into the chamber for their reception from the main pipeline works as follows.

In preparation for reception, a finger 12 is installed in a chamber for receiving a flow projectile moving along the main pipeline 12 in one of the landing holes 13 at a distance from the closest weld 19 of the stop valve 15, slightly exceeding, for example, 100 mm the length of the flow projectile.

The flow projectile, moving along the main pipeline, enters the chamber for reception through the shutoff valve 15, the linear pipe 14, the adapter 16 and acts through the spherical head 17 on the finger 12, imparting forward movement with acceleration of the inner pipe 6. Moreover, the impact through the spherical head 17 on finger 12 occurs in the form of an impact, that is, the flow projectile “hits” the spherical head 17.

After hitting the flow projectile on the spherical head 17, an arcuate bracket 8 located on the inner tube 6 acts on the lower lever 3, which in turn drives the connecting rod-pusher 2 with the spring lever 4, after which the spring lever 4 disengages from flag 5.

Flag 5 in this case takes a vertical position, thereby signaling the passage of the flow projectile into the receiving chamber, and finger 12, progressively moving with acceleration from the impact of the flow projectile along an extended groove 11, leaves contact with the flow projectile.

Thus, with the described method of using a mechanical signaling device for the passage of in-line projectiles into the chamber for receiving them from the main pipeline manufactured using the claimed utility model, the latter is fully implemented and, as a result, the indicated technical result is achieved.
