The method of transportation of goods by water in winter

 

(57) Abstract:

The invention relates to transport, specifically for the transportation of goods by ice-covered waters. The aim of the invention is the transportation of cargo on ice without its preliminary hardening in the way of cargo. This goal is achieved by the fact that the method of transportation of goods by ice-covered waters, which before placing on ice and navigation of cargo reinforce ice cover, in contrast to known methods, creates a local hardening of the ice cover directly under the load, which is achieved by placing under the ice compensating device variable buoyancy with buoyancy, approximately equal to the weight of the cargo and peremeshivaemogo in parallel with the load. This helps to reduce the bending stresses in the ice cover and thereby significantly increase its carrying capacity. The proposed method of transportation of goods can be widely used in sparsely populated areas of Siberia and in the development of oil fields in the North sea. Expand the functionality of the method. 2 C.p. f-crystals, 1 Il.

The invention relates to transport, and specific Ravi through water barriers in the winter.

The invention can also be used in the construction of bridges by the method of slipped on easily spans.

There is a method to overcome water obstacles is the construction of bridges across rivers, Straits, etc., But the length of the bridges is always limited. In addition, this is an expensive construction and stationary, which reduces its effectiveness in sparsely populated areas.

There is a method of transportation of goods by water with ships, ferries and other ships. They allow you to transport goods over any distance on the water. However, the effectiveness of their use in the winter, especially in the Northern parts of Siberia, is sharply reduced because of the formation of ice on the water. In addition, when transporting bulky cargo can cause problems with loading and unloading.

There is a method of transporting cargo on rivers and lakes in the winter, where the transportation of cargo strengthen formed in the winter of the ice cover along the entire length of road transportation /see, for example, SU inventor's certificate, 1609849, CL E 01 D 15/14, 1988/.

This method allows for the transportation of goods by water in the winter perivitelline low cost eliminates handling operation.

However, with increasing length of road transportation in the mentioned way proportionally increase the cost of preparing the way.

In addition, training the way you have to make anew each year, which reduces the effectiveness of the method.

This decision was made as a prototype.

The purpose of this invention is the provision of transportation on ice-covered waters in the winter without preliminary hardening of the ice cover in the way of cargo.

This goal is achieved by the fact that the method of transportation of goods by ice-covered waters, which before placing on ice and navigation of cargo reinforce ice cover, in contrast to known methods creates a local hardening of the ice cover directly under the load by reducing the stresses caused by bending of the ice cover under the load.

The reduction of stresses in the ice cover is, for example, by placing under ice cover self-propelled or nonself-propelled compensating device. The compensating device having sufficient buoyancy, pressure from below on the ice with the power, pribliziteljny, and compression ice works much better than bending. In addition, the compressive stress can be easily reduced by increasing the contact area.

When the movement of the load compensating device also moves under the ice parallel to the load, which ensures local maintaining a constant stress state in the ice cover directly under the moving load.

To avoid cracking of the ice in the absence of a load compensating device placed under the ice cover with pre-reduced buoyancy, and in the process of placing over it cargo buoyancy increase to the amount at which the buoyancy force on the compensating device, becomes approximately equal to the weight of the cargo.

These signs are new, meet the inventive step and are industrially applicable for the transportation of cargo and other tasks.

The drawing shows a scheme of transportation of goods, where:

1 - ice cover on the surface of the water,

2 - self-propelled or nonself-propelled compensating device,

3 - transported goods, for example, rig,

4 - tractor.

The way assests the second or dumb. Its buoyancy is reduced to prevent the cracking of the ice from below. Ice over compensating device is transported cargo 3, and simultaneously increases the buoyancy compensating device to a value so that the buoyancy force was approximately equal to the weight of the transported goods and complex vehicles. After that, the load 3 and the compensating device 2 is moved in parallel to the destination.

In shallow waters can be applied to the compensating device, in which the compensating force is created not by the change of buoyancy, and the emphasis in the bottom.

The proposed method of transportation has the following advantages: unlimited length transportation within ice-covered waters, low cost technical means for implementing the method, high maneuverability, allowing you to effectively carry out cargo transportation in sparsely populated areas: in areas where there is a ferry, it can operate in the new mode according to the proposed scheme in the winter period, the compensating device can be used to transport cargo and open water in the project far in the sea that is topical in connection with the development of oil fields of the North.

1. The method of transportation of goods by ice-covered waters, which before placing on ice and navigation of cargo reinforce ice cover, characterized in that the hardening create directly under the load by reducing the stresses caused by bending of the ice cover under the load.

2. The method according to p. 1, characterized in that the reduction of stresses in the ice cover is carried out by placing under ice cover self-propelled or nonself-propelled compensating device having variable buoyancy, and the movement of goods carried out in parallel with the movement of the compensating device.

3. The method according to p. 2, characterized in that the compensating device set under the ice cover with pre-reduced buoyancy, and when placed over it cargo buoyancy increase to the amount at which the buoyancy force on the compensating device, becomes comparable with the weight of the cargo.
