The invention relates to the equipment for clearing of the underwater base, equipped with cargo to align the submarine base and a device for detecting the location levelled surface.

You know the equipment intended for the formation of the underwater base of stone backfill, by the attack by dropping cargo 1, suspended from a crane. As you can see from 6, this equipment to align submarine base constructively with tubular rod 2; cargo 1, attached to the lower end of the rod; 3 hooks for fastening of rope on the upper end of the rod; and cable 4, coupled with a crane on Board the vessel. The alignment of the underwater base is carried out by the attack by dropping cargo 1 when it is re-raising and lowering.

To achieve the required size and height of base formed by dropping cargo 1, provides for the detection location align bottom surface.

To detect the location align the surface there is a method of using a measuring device to determine the location 7, equipped with sotapanna 6, radiant beam and reflectors 5 installed on the upper outer perimeter of the rod 2, and receiving the reflected beam from them. Location levelled surface is measured by calculating device 7 height and planar coordinate reflectors 5 of the parameters of the reflected beam and' (See. patent document 1).

If the measuring device 7 may determine the location of reflectors 5 of the parameters of the reflected beam and'you can also specify the location of your cargo 1 taking into account the length of the rod 2. This implies that the location of the bottom surface of the cargo 1 corresponds to the location levelled surface.

As stated above, to detect the location levelled surface mounted reflectors 5 on the upper outer perimeter of the rod 2.

To ensure the smooth lowering 1 provides free unwinding cable with an unspecified figure drum for reeling the cable 4 attached to the hooks 3, so that the cable does not obstruct free lowering cargo 1.

However, when cargo 1 stops, faced with levelled surface, cable 4 may inertia to blur with the above drum more than you need, then slack.

When confronted with levelled surface cargo 1 may bounce, causing the slack of the rope 4.

It is almost impossible to exclude the slack of the rope 4. If excessive slack rope 4, as shown in figure 7, the slack cable 4 may hit the reflectors 5. Cable 4, intended for lifting rod 2 with cargo 1, performed strongly with thick, meeting the requirements of high strength.

Clash of the cable 4-surface reflector 5 may lead to their damage or the pollution of their surfaces, which in turn can cause a number of problems hindering the correct location align surface, such as the inability reflection of the beam, angle of reflection of the beam, the decrease of intensity of the beam, etc.

The invention aims to offer the equipment, which even in the case of slack from the rope attached to the boom with cargo and excludes the possibility of collision of a cable with reflectors.

The first invention relates to the equipment for clearing stone backfill forming underwater base, consisting of rods; cargo, fixed on it; reflectors installed on the upper outer perimeter of the rod; and rope. The alignment of the underwater base by lifting rod with a weight at the rope with their further lowering its own weight, and the detection of the location of levelling the surface is carried out on the parameters of the beam reflected from the reflectors on svetoproekt. First invention is different in that you have a protective structure that protects the reflectors from a collision with the above slack rope, and also provides area passes rays in the place corresponding to the path of the beam reflected from the reflectors on svetoproekt.

The second invention is different in that the above protective design is installed on the above reflectors, and under the protective design provides the above area passes rays. This protective structure advocates the circle formed continuously placed reflectors. This construction is so slack rope not hit the reflectors when the cable has faced its edge.

The third invention differs in that the above protective design has a dome-shaped form.

Fourth invention differs based on the first invention installed a pair of protective detail above and below the above reflectors, and between protective details provided above area passes rays. Each protective detail stands for a circle is formed continuously placed reflectors. This construction is so slack rope not hit the reflectors when the cable has faced its edge.

Fifth invention differs based on the first invention protective construction is executed in execution, covering the whole of the above reflectors, and on the design envisages the above area passes rays.

According to the inventions 1-5, even if the cable slack when lowering of cargo, cable 4 not hitting reflectors prevent their damage or contamination that constantly provides correct positioning is levelled surface.

The second invention allows to simplify configuration of the protective structure, just providing the path of the reflected beam.

The third invention gives protective structures dome-shaped form that allows you to protect the protective design by a blow from a rope and thus increase its longevity.

On the fourth invention even if excessive sagging cable protective design can protect reflectors by a blow from a rope.

Fifth invention allows more true to protect reflectors by a blow from a rope, regardless of the length of the slack from the rope.

Fig.7 - front View of the main part of the example of the existing equipment.

To the first variant of the invention, shown in figure 1, is the installation of protective structures over 8 reflectors 5 on the rod 2 fixed on cargo 1. This variant of the invention has the same configuration as for existing equipment, shown in Fig.6, except for installation of protective constructions above 8. Variant operation is also one and the same as for the existing equipment.

This protective structure 8 is a metal disk detail welded to the rod 2.

Diameter of disk details, part of the above protective design 8, provides greater than the diameter D of the circle formed by continuously placed reflectors 5, so that the slack rope 4 not hit the reflectors 5, even if the cable is faced with the edge of protective constructions 8.

That is, above the protective structure 8 stands for a circle is formed continuously placed reflectors 5 so that the slack rope 4 not hit the reflectors 5, even if the cable is faced with the edge of protective constructions 8.

Thus, even if the cable 4 slack in the process of aligning the bottom of the reservoir with the cargo 1, the cable does not hit about reflectors 5, without causing damage or the pollution of their surfaces.

Besides the above protective design 8 installed only on reflectors 5, allowing you to free up space under the protective design 8 and thus envisage the area of missing beams on this invention.

Therefore, the protective structure 8 shall not prevent the path of the beam reflected from the reflectors 5, for detecting the location levelled surface.

Thus, the equipment for clearing of the submarine base on the first version of the invention, provides constant correct positioning is levelled surface without damage or contamination of reflectors 5 sagging wire 4.

If the security design 8 made of sheet parts, then it is beneficial to simplify the configuration of your security design, easy to providing a sufficiently large area passes rays.

In the case of the first variant of the invention of the above protective design 8 made of disk details. But its form is not limited to the disk. If the protective structure advocates the circle formed continuously placed reflectors 5, it can be any, as, for example, polygon.

The location of protective constructions 8 in relation to the reflectors 5, may exclude the possibility of collision of a cable with reflectors in the collision of a cable with protective edge design, depends on the length of slack from the rope 4, vertical location of protective constructions 8, degree ledge protective constructions 8, i.e. its diameter. Therefore, the invention may be carried out by regulating other parameters depending on the length of the slack from the rope 4, intended for alignment of the underwater base with the help of this equipment.

According to the second variant of the invention over the reflectors 5 on the rod 2 is fixed dome-shaped protective design 9. The protective structure 9 stands for a circle is formed continuously placed reflectors 5.

Bottom, the most wide part of a protective design 9 is higher than reflectors 5 to the space under the protective design 9 served as a zone of crossing rays. [0019]

The above configuration allows you to avoid blocking the path of the ray protective design 9 for detecting the location levelled surface. As can be seen from the figure, even if the slack rope 4 faces protective design, it does not hit about reflectors 5 without damaging or polluting them.

Technical decision on giving protective constructions 9 dome-shaped provides increase its resistance to prevent deformation and damage the impact of a crash with a cable of 4.

Rounded surface protective dome design 9 facing sagging wire 4, allows to weaken the power cable 4 aimed towards reflectors 5. As a result, even if the length of the slack from the rope 4 exceeds the estimated value, and the cable 4 facing reflectors 5 under the protective design 9, the force of the impact can be reduced in order to avoid damage to the reflectors 5.

The third variant of the invention, shown in Figure 3, is made with a protective design 10, consisting of protective sheet items 10A and 10b, installed above and below the reflectors 5. The rest of the configuration of this option except protective structures 10 is the same as for the first variant of the invention.

On protective structures 10 provides area passes rays between the protective parts 10A and 10b, and protective items 10A and 10b advocate the circle formed continuously placed reflectors 5.

The above technical solutions for the installation of protective constructions of 10 allow to prevent a collision of a cable with 4 reflectors 5 by blocking slack rope 4 edges protective parts 10A and 10b. In particular when excessive length sagging wire 4 is faced with a protective item 10b, established under the reflectors 5, avoid contact with reflectors and thus their damage and contamination.

Thus, on the equipment for clearing of the submarine base on the third variant of the invention also eliminates the risk of damaging the reflectors 5, which provides correct positioning is levelled surface.

By the third variant of the invention above a pair of protective parts 10A and 10b made in sheet form. But form a protective parts 10A and 10b not limited sheet. For example, protective items 10A and 10b can be performed in a domed shape. In particular, if the upper protective item 10A made in the dome-shaped form, as well as according to the second variant of the invention, increased the resistance of protective items 10A, with the rounded surface of the dome-shaped protective details may weaken the force of impact at collision with a cable of 4

On the fourth draft of the invention, shown in figure 4, on the rod 2 is installed karinovasa metal protective design 11, cover the entire reflectors 5.

Karinovasa protective design 11 by this option the invention, consists of the ring part 11a, attached to the barbell over 2 reflectors 5; ring 11b details below and in parallel with the ring item 11a with a diameter greater than 11a; rack parts 11S connecting vertically ring details 11a and 11b; and circular parts 11d and 11th situated between the ring parts 11a and 11b and attached to the rack detail.

Reflectors 5 placed in the apertures formed between ring parts 11d and 11th, and pinion details 11S so as to envisage the area passes rays 12. Therefore, the protective structure 11 cannot block the path of the reflected beam.

Above the ring details 11d and 11th made with diameters greater than the diameter of a circle formed by continuously placed reflectors 5, so that these details are advocated this circle.

Thus, also in the case of the fourth variant of the invention, as can be seen from the figure, the slack cable 4, although faced with a protective design of 11, but are not faced with reflectors 4 in order to avoid their damage or contamination.

In particular, on the fourth draft of the invention, the technical solutions for the complete coverage of reflectors 5 protective design 11 allow more true to prevent a collision of a cable with 4 reflectors 5 out-depending on the length of slack from the rope.

Protective design 11 can be made in removable performed on the rod 2 if to divide each of the circular parts of 11a, 11b, 11d and 11th at 2 half and then connecting 2 halves hinges on one side and disconnecting and connecting parts on the other.

Explanations about the variants of the invention 1-4 filed in connection with the equipment for clearing of the underwater base, equipped with a tubular rod 2. Protective design for this invention can be used for any equipment for surface levelling stone backfill with the help of cargo, equipped with reflectors to locate align the surface, regardless of the configuration of the rod and the form of the cargo.

Figure 5 shows the fifth variant of the invention, on which cargo 1 is supported on the master boom 13. On the upper outer perimeter of the rod 13 reflectors installed 5 over which enshrined the protective structure 9, the same as that for the second variant of the invention, shown in figure 2.

In the case of the fifth variant of the invention, as well as for the second variant of the invention, the slack cable 4, although faced with a protective design of 9, but are not faced with reflectors prevent their damage or pollution.
