Description

The utility model relates to protective devices or devices for monitoring equipment (F17D 5/00).

Due to the increased danger of the operation of oil pipelines associated with pumping oil or oil products under high pressure, increased demands are placed on the control of the state of the pipeline. As the main controlled parameters are used: pressure in the pipeline and the temperature of the pumped product. Accurate equipment is used to measure and transmit data on both controlled parameters, which, despite the increased strength requirements, needs additional protection against adverse environmental factors. At the same time, this equipment needs periodic technical inspection and maintenance, and therefore, it is necessary for service personnel to have free access to the specified equipment. In order to solve the tasks, a well was developed to provide monitoring and access to pipeline equipment

Several developments are known which are wells for accessing pipeline equipment, namely, patents of the Russian Federation 115039, 105712, 76031, 76030, 62207. Considering the design of the well and the method of its attachment to the pipeline, the well presented in the utility model is accepted as the closest analogue: A well for monitoring the operation of the pipeline and its equipment ”(patent No. 62207, published March 23, 2007). This development contains a hollow well body with two holes and a cover, a coupling half and a half ring.

The disadvantages of this development are the low ergonomic characteristics of the device for attaching the cover to the body of the well, which does not allow for quick access to the inside of the well, insufficient durability of the fastening due to increased loads on the shaft of the fastening of the cover to the well (it is the mechanism for opening the cover of the well), and the small volume of the internal space of the well for placement appliances.

The technical result of the claimed device is to increase the durability of the device for fastening the lid of the well, increasing the speed of personnel access to equipment located inside the well, as well as increasing the internal space of the well for placing devices without increasing the size of the cover.

The specified technical result is achieved by solving the following tasks:

1. Creating a simplified design for attaching the well cover to the body of the well, by using a reinforced hinge welded to the body of the well, and two loops welded to the body of the cover.

2. Changing the design of the well in order to increase the internal space by partitioning the latter into the well itself and the neck of the well with the same diameter under the existing standard size of the well cover.

Like the closest analogue, the well for monitoring and access to the pipeline equipment contains a hollow body, a coupling half and a half ring for a tight, fixed connection of the body to the pipeline.

Unlike the closest analogue, the housing of the claimed device is equipped with a neck welded to its upper part to install the well cover, as well as a cover attachment unit to the well body, made in the form of a hinge welded to the well body, and two loops welded to the cover body. An emphasis in the form of brackets is welded at the location of the attachment point to the body of the well cover, with the possibility of installing studs to lock the well cover.

The shaft is made of high strength steel with additional grooves to simplify the lubrication of friction surfaces. To avoid the ingress of dust and other fine foreign media. An emphasis is installed to protect the cover and personnel from uncontrolled reverse falling of the cover to the neck of the well and prevents the cover from moving in the opposite direction from closing.

For ease of opening, the well cover is equipped with at least one handle of any design. The handle / s can be installed anywhere on the cover, for example, opposite the attachment point of the cover to the well body.

The design of the well is shown in figures 1, 2, 3, 4 with the following notation:

1 - Pipeline;

2 - well body;

3 - well cover;

4 - Pipe ventilation;

5 - the neck of the well;

6 - Half ring;

7 - Half coupling;

8 - Pipe for cable entry;

9 - emphasis;

10 - Hinge;

11 - Joint shaft;

12 - Groove of the hinge shaft;

13 - The handle of the well cover;

14 - Loops;

15 - Hole for installing the locking pin.

Using the half ring 6 and half coupling 7, the body of the well 2 is hermetically and motionlessly attached to the pipeline 1 (Figure 1, Figure 2). To access the equipment inside the well, the neck of the well is equipped with a well cover 3 (Fig. 1, Fig. 2). The attachment of the cover to the body of the well (Figure 1, Figure 3) is made in the form of a hinge 10 and two loops 14. By attaching the cover of the well 3 to the body of the well 2 through the hinge 10, maintenance personnel can quickly access the equipment being serviced. The design of the hinge 10 is shown in figure 3, 4. The hinge 10 consists of a shaft of the hinge 11 with grooves 12 and two loops 16, welded to the body of the cover of the well 3. The shaft of the hinge 11 is made of high strength steel, providing greater durability of the hinge 10. The groove of the shaft hinge 12 (Figure 3) is provided for free lubrication of the hinge 10. The handle of the lid of the well 13 is designed for convenient opening of the lid by personnel. In the location of the attachment point, an emphasis in the form of brackets 9 is welded on the outside of the casing and the lid of the well with the possibility of installing a stud to lock the lid of the well. The stop 9 allows you to prevent an uncontrolled fall of the lid of the well 3 on the supply and exhaust ventilation pipe 4 with its subsequent damage (Figure 1). At the same time, by installing the studs in the holes 15 of the stop 9 (Fig. 1) and then fixing them with nuts, the lid of the well 3 is blocked from inadvertent closure, for example by a gust of wind. The supply and exhaust ventilation pipe 4 (Figure 1) is intended for free air circulation in the inner section of the well and to prevent the accumulation of oil vapor inside the well in case of a leak in the pipeline 1 at the installation site of the well. The pipe for cable input 8 is intended for input into the well body 2 of cable products for power supply and data collection from monitoring devices for the operation of the pipeline (Figure 1). The neck of the well 5 allows you to increase the internal volume of the well to accommodate more equipment and space to work with it without increasing the size of the cover.
