Description

The invention relates to pipeline transport, in particular to protective devices for the support of pipelines through water barriers.

Known typical designs of pipe supports installed when laying pipelines through river channels or other water barriers [1] (http://www.theglobeandmail.com/globe-investor/alaska-plan-intensifies-gas-race-to-asia/article4590398 /, photo 1),

[2] (http://en.depositphotos.com/3909007/stock-photo-transition-of-two-pipelines-through.html, photo 2). Such supports do not have protection against the effects of ice masses, rock-carrier, river sediments and can be subjected to significant loads, which can lead to damage and failure. In addition, such supports can cause river congestion during ice drift, car-walker (photo 2), which can lead to clogging of river channels, products of the car-walker or river sediment.

The closest in technical essence to the achieved result is the installation of the ice-cutting part of the intermediate bridge support [3] (RF Patent No. 2246575). The device includes the upper part of the support, rigidly connected with the crossbar supporting the span, installed in the body of the ice-cutting part, made of concrete filler, enclosed in a shell, resting on the foundation grillage, creating a single monolithic structure with it. At the same time, the ice-cutting part is provided with a shell made of a rectangular part and two rear parts of a triangular configuration, connected to the rectangular part by bolt connections, and which is an integral structure in height of the ice-cutting part, the shell is made of welded sheets repeating the contour of the ice-cutting part, hermetically fastened between by yourself in a welded way. The triangular configuration of the tail sections of the shell allows you to reduce the impact of direct physical exertion during ice formation, a walk-in walk, and other foreign floating objects. A disadvantage of the known device is its lack of effectiveness with a carriage walk, since the roots, branches and branches of trees can, under certain conditions, be held by the ice-cutting part, which can create a risk of congestion. In addition, the known device is material-intensive and cumbersome for use as a pipe support.

The aim of the present invention is to eliminate these drawbacks, as well as extending the scope of the protective device to the supports of pipelines through water barriers.

The specified goal is achieved through the use of:

- mounted on the axis, in front of the support, at an angle to the vertical, of the floating impeller;

- ball bearings or friction bearings, which ensures constant rotation of the impeller on the axis under the influence of the river flow, as well as moving it up and down along the axis when the water level in the river changes.

The essence of the present invention lies in the fact that the claimed protective device of the pipe support, including the vertical part of the support installed in the foundation grill, according to the invention, has a floating impeller mounted in front of the vertical part of the support and at an angle to it, which is mounted on an axis, fixed with brackets on the vertical part of the support, while the floating impeller to the axis is mounted on ball bearings or friction bearings, which ensures constant rotation of the blades wheel under the influence of the river, as well as moving it up and down when the water level in the river changes.

In FIG. 1 shows a General diagram of the inventive protective device support pipe, where:

1 - vertical part of the support;

2 - foundation grillage;

3 - floating impeller;

4 - axis;

5 - bracket;

6 - ball bearings or friction bearings.

A floating impeller 3 is installed on the vertical part of the support 1, installed in the foundation grill 2, which is mounted on an axis 4, fixed with brackets 5 on the vertical part of the support 1. The floating impeller 3 to the axis is mounted on ball bearings or friction bearings 6.

In FIG. 2 shows an installation option of the inventive protective device support pipe.

The proposed protective device support pipe works as follows.

The inclination of the axis 4 (see Fig. 1, view A) and the presence of ball bearings or friction bearings 6 provide rotation of the floating impeller 3 on axis 4 towards the center of the river channel. The buoyancy of the floating impeller 3 is provided by its hollow design. When touching the ice masses moving along the river, the carriage walker, river sediment, and other foreign floating objects of the floating paddle wheel 3, which rotates under the influence of the river flow, the floating objects shift towards the center of the river channel, thus preventing them from catching on the vertical part supports 1 and thereby reducing pollution of the coastal part of the river.

It should be noted that for optimal operation of the protective device of the pipeline support, the floating impeller 3 should be immersed in water half (± 10%), and the inclination of the axis 4 (see Fig. 1, view A) should be

In the event that the vertical part of the support 1 is installed in the middle of the river bed, it is allowed to set the axis 4 vertically (see Fig. 2), while the floating impeller 3 is stationary and turns only when physical stress occurs when the carriage walker or in contact with other foreign floating objects , thus, passing them by the vertical part of the support 1.

Thus, the inventive protective device supports the pipeline performs two functions: protects the supporting structure of the support from the effects of ice drift, carcass and other foreign floating objects; prevents ice masses, products of the carriage carrier, other floating objects from catching on the support, thereby preventing the formation of river jams.
