Description

The utility model relates to a modular cable penetration for airtight cable routing through a wall and is intended for use where a protected laying of electric cables of various designs is required, a protected laying of pipelines of various sizes and non-aggressive purposes through any obstacles in structures and structures (steel, concrete, brick, wood, polymer, etc.) while maintaining the fire resistance category.

The term "cable" hereinafter should be interpreted in a broad sense as pipes or wires, which is obvious to a person skilled in the art. For the purposes of this utility model, the term “line” will be used. A line refers to elongated objects such as a cable, pipe, pipe or similar object.

The modules allow sealing against the effects of liquid, gas, fire, rodents, termites, dust, moisture, etc. and accommodate electrical cables, communication cables, computer cables, etc. or pipes for various gases or liquids, such as water, compressed air, working fluid and household gas.

The level of technology.

Various systems are known for receiving cables, wiring pipes, and the like, passing through a wall, roof, floor, and the like. in buildings and structures.

These systems for receiving cables, wiring pipes usually contain a frame that is inserted into the wall and has an internal through-hole for pipes, cables, etc. Inside the frame there are several modules made of elastic material for receiving individual cables and / or pipes. In addition, there is usually a clamping device of one type or another for sealing cables and / or pipes. To adapt the inner channel to the line, an insert is provided from a plurality of radially separated layers that are separated from each other to adapt the passage through the channel to different installation dimensions of the line, for example, according to patents No. 2337445 [1], No. 2270392 [2], No. 143139 [3], No. 110163 [4], No. 2319057 [5].

In known systems cable adapter, pipe input, etc. in the seal as a whole has a cylindrical shape and should be placed in the sleeve in the wall or in the hole in the wall. For the seal to function in the desired way, it must fit snugly against the sleeve or hole in the wall in which it is placed, and must be adapted to fit the actual installation dimensions. The mounting dimensions are determined by the inner diameter of the sleeve or hole. The sealant has a cylindrical compressible housing, which is axially compressed between the regulators located at opposite ends of the compressible housing. Under axial compression, the cylindrical body will radially expand both inward and outward.

In addition, the inserted pipes, wires or cables may have different external diameters, and thus, the module must be adapted to cables or pipes having different external diameters.

Gaskets should be suitable for use with cables or wires of various types: electric, communication cables, computer cables, etc., pipes for various gases or liquids such as water, compressed air, hydraulic fluid and cooking gas, and wires to hold the load .

Parts into which a single cable or the like is inserted often have peeling layers or sheets inside the stack. Layers or sheets are removed until the inner diameter of the part is adjusted to the outer diameter of the cable inserted into the specified part. The sheets are glued to each other tightly enough to remain connected to each other and, at the same time, loosely enough to make it possible to separate them from the common foot one by one, or several pieces at once. In some embodiments, said parts comprise peelable layers or sheets on their outer surface, which makes it possible to fit the outer dimensions, for example, a round seal to a specific hole or sleeve.

The disadvantage of this design of the transition device is the complexity of its compressible blocks, when due to the many detachable layers it is impossible to guess the necessary degree of compression of the sealed element or return to compression of the element of a smaller diameter.

 The closest set of essential features selected device according to the patent for invention No. 2280933 [6].

The known device contains a clamping frame (11) and many blocks that together fill the frame (11). At least one of the blocks (5) has a through-passage channel (5) for receiving the line (41), and the block (5) is configured to introduce a line (41) sideways into the channel (51). The device also includes a separate tubular liner (1) made of an elastic material. The liner (1) has a substantially axial through-slot (3) extending in its wall to allow the liner to be installed sideways on line (41) and has an external cross section substantially corresponding to the cross section of the channel (51) in block (5). Like the previous mentioned devices, the liner contains many radially separated layers (2), which are separated from each other to adapt the passing through the channel (8) of the liner to the line (41).

 The problem solved by the claimed utility model is the creation of a universal cable penetration for various types of cables, tubular products in a wide range of sizes and profiles.

Plug-in cables, wires or pipes can have different external diameters, and thus the module must be adapted to fit cables or pipes with different external diameters.

Versatility is ensured by the possibility of installing modules with typical overall and mounting dimensions, with a clamping device corresponding to each type of module and the ability to install any type and cross-section of a cable or pipe by selecting the appropriate insert into the module, as well as the ability to install several cables of different or similar cross-sections into one module.

The technical result consists in expanding the arsenal of technical means related to cable penetration devices.

The technical result is achieved in that the cable penetration device comprises a frame and one or a plurality of block modules that fill the frame, the block module comprising a body made of elastic material with a through channel for accommodating the line and an insert with an external diameter, corresponding to the diameter of the channel in the block, as well as the compression block, while the inserts are made of elastic material; moreover, the insert has at least one through cavity to accommodate the line, and each through cavity is provided with a longitudinal slot for introducing a line extending from the outer surface of the insert to the through cavity; the device is equipped with a compression device in the form of compression plates mounted on opposite sides of the module housing and connected by a coupler; while the device is equipped with a pressing plate to hold the block modules.

At the same time, the block modules are made with unified overall and landing dimensions.

Moreover, the block modules are made with one, two and three channels.

At the same time, the block modules are made of a silicone compound of cold forced curing or two-component polyurethane.

At the same time, the insertion of the block modules is made with the overall and landing dimensions corresponding to the overall and landing dimensions of the block module housings, for installation in channels.

In this case, the inserts are made with cavities in an amount of from 1 to n.

In this case, the diameters of the cavities are unified for the possibility of installing several cables of different or the same cross-section in one module.

In this case, the inserts are made of a silicone compound of cold forced curing or two-component polyurethane.

Moreover, the compression device is made with compression plates having holes corresponding to the number and size of the diameter of the channel channels of the module.

In this case, the pressing plate is made with bent sides.

The list of positions:

sealing modular block 1, hereinafter referred to as block module;

compressible housing 2;

sealing insert 3;

compression device 4;

first compression plate 5;

second compression plate 6;

screws 7;

guides 8;

pressing plate 9;

frame 10 for rigid framing the opening in the wall (floor, ceiling);

a through cylindrical channel 11 in the housing 2;

holes 12 in the housing 2 for mounting the compression device;

holes 13 for the channel in the compression plates of 5.6;

cavity 14 in the insert for laying the cable;

longitudinal slot 15 inserts.

The inventive cable driving device is a frame frame 10, framing a hole in the wall (floor, ceiling, etc.) (Fig. 1,4), filled from one or more sealing modular blocks 1 (hereinafter - block modules 1) . The inventive cable penetration may contain one sealing block module or more sealing block modules, without changing the volume of this utility model. The sealing block module 1 comprises a compressible housing 2 provided with at least one through cylindrical channel 11 for receiving cables and / or pipes of the line (Fig.1-4). The compressible casing 2 is made of an elastic material — an elastomer, which can be used cold forced curing silicone (silicone compound) or two-component polyurethane, in which various isocyanate compounds are used as the first component, and compounds containing hydroxyl groups as the second component (see . https://polimerinfo.com/poliuretan/dvuhkomponentnyj-poliuretan.html).
Compressible housing 2 is also equipped with mounting holes 12, designed to be placed and fixed on its opposite sides of the elements of the compression device 4 (Fig. 5).

On the housing 2, compression plates 5 and 6 of the compression device 4 are fixed on both sides. The plates are made with holes 13 corresponding to the number and size of the diameter of the module channels.

 The plates 5 and 6 are interconnected through the through holes 12 with fasteners, for example, an adjusting screw 7 and a guide 8 with internal thread (figure 4), performing the function of a coupler.

 Sealing inserts 3 have a cylindrical shape and are intended to be inserted into the housing 2 of the block module, placed in the opening of the frame 10 (Fig.6, 6). Sealing insert 3 provides direct sealing of the laid cable (s), pipes in various laying options in accordance with the requirements of the project. To this end, the sealing insert 3 comprises at least one cylindrical cavity 14 provided with a longitudinal slot 15 for introducing a line and extending from the outer surface of the insert to the through cavity 14 of FIG. 6).

For proper functioning, the sealing insert must enter, without a gap, into the channel 11 of the module housing 2 and must be able to seal the line (cable or pipe) laid through its cavity 14.

Box 3 is made of an elastic material — an elastomer, which can be used cold forced curing silicone (silicone compound) or two-component polyurethane (see https://polimerinfo.com/poliuretan/dvuhkomponentnyj-poliuretan.html).
When tightening with screws 7, the housing 2 of the module is compressed axially between the compression plates 5,6 of the compression device 4 located at opposite ends of the compressible housing 2, and exerts pressure on the sealing insert 3, which in turn leads to its compression in the axial direction and causes its expansion in the radial direction inward and outward. In this case, the elastic, elastic insert will compress the cable, wires or pipes, filling the voids in the cavity 14.

  To be able to install any type and cross-section of the cable by selecting an insert, as well as the ability to install several cables of different or similar cross-section into one module, the insert is made in a modular solution, while a set of inserts 1,2,3 ... n with one or more holes and the established dimensions of the diameters of the holes of the cavity 13, corresponding to the permissible diameters of the cables or pipes. Examples of implementation are given in Tables 1,2,3.

The insert can be made with backup holes-cavities 14, for which there are plugs (. Table 2. No. 13,26,35,41) also of elastic material.

Such a design makes it easy to coordinate the block modules 1 with different sizes of cables or pipes due to the presence of inserts 3 with a different number of internal cavities and the corresponding optimal sizes of their internal diameters (table 3).

The separation of the cases 2 modules between themselves, keeping them from falling out is ensured by the pressure plate 9, which is made of sheet metal and equipped with bent sides (figure 4).

Plate 9, in addition, facilitates the replacement of the module with another standard size without disassembling the entire structure. Two parallel edges of the sheet are made with bent sides to ensure the rigidity of the plate and the convenience of its operation during installation.

Examples of specific performance.

Example 1. The cable penetration device comprises a frame and one block module, the housing of which is made of a silicone compound of cold forced curing. The housing 2 of the block module is made with one hole (see table 3) with a diameter of 15 mm, in which an insert 3 with a corresponding external diameter is placed. The insert is made of a silicone compound of cold forced curing. The insert contains two internal cavities of large diameter and two internal cavities of small diameter, for example, No. 1 of Table 2. The device is equipped with a compression device in the form of compression plates mounted on opposite sides of the module housing and connected by a screed; while the device is equipped with a pressing plate to hold the block modules.

Example 2. The device is made in accordance with example 1, however, the housing is made with two holes (see table 3), in which there are inserts 3 with the corresponding outer diameter. In this case, one insert contains one internal, for example, No. 9.10 of Table 2.

Example 3. The device is made in accordance with example 1, however, the housing is made with three holes (see table 3), in which there are inserts 3 with the corresponding outer diameter. Moreover, one insert contains one internal cavity, for example, No. 9 of Table 2; the other insert contains 18 internal cavities, see No. 25 of table 3, and the third hole is closed with a plug, for example No. 26 of table 3.

Example 4. The device is made in accordance with examples 1-3, but the body and insert are made of two-component polyurethane.

Cable entry assembly

In the rectangular hole of the frame 10, rigidly framing the opening in the wall (floor, etc.), a pre-assembled sealing block module 1 is installed. The assembly of the sealing block module consists in connecting the compressible housing 2 with the clamping device 4, namely: plate 5.6 with the ends of the housing 2; guides 8 are inserted into the corresponding holes 12 of the first compression plate 5, then into the holes 12 of the module housing 2 and the corresponding holes 13 of the second compression plate 6, and are fixed with clamping elements, for example, screws 7.

 The assembled module with compression clamp is installed in the frame 10. Then, a line is drawn into the assembled module (cable of the desired cross section or pipe). A sealing insert 3 is selected on the line, which, through the slot 15 along the entire body of the insert, is put on a cable or pipe. Next, move the insert 3 into the hole of the channel 11 of the housing, aligning with a cut hole. Thus, they continue to assemble the housings until the frame 10 is completely filled, pressing clamping plates 9 inserted between each subsequent housing. When the assembly process of the housings, lines and sealing inserts is completed, the clamping screws 7 are tightened.

When installing the frame in the wall in an upright position, the case is laid down on the frame 10, then the pressure plate 9 is installed, the next case is placed on top of it (on top of each other) and the whole volume of the frame 10 is filled in. Reserve openings are closed with plugs.

When installing the frame 10 in the floor horizontal position, the housing is inserted into the frame on the right or left, then the pressure plate 9 is installed, which allows the housing to be kept from falling down. Then fill the frame with cases left or right with the installation of plates 9 between each.

For the lower case, the rigid frame is the three walls of the frame 10, for a rigid frame of the opening in the wall (floor, ceiling) and for the places of contact of adjacent buildings, a plate 9 is used.

The plate 9 equalizes the pressure from the neighboring housing and does not allow it to stick together when heated to high temperatures or in case of fire, and when replacing the sealing inserts, the installer facilitates the work process.

The uniform distribution of pressure and the compression of the elastic material from which the module housings and sealing inserts are made in different directions, the presence of a pressure plate will allow you to rigidly fix the line in the cable penetration and provide sealing of the interior space from moisture and dust from the outside, as well as provide the necessary fire resistance.

 The inventive cable driving device provides simple reliable sealing, sealing and fixing of cables, wires, pipes, cables, lines and the like products, i.e. lines in the wall, wiring closet and similar structures, as well as their operational with high performance (high speed) and multiple installation-dismantling, changing the size and replacing one with another. In addition, for the sealing module, it is easy to select the required bore of the sealing element and the simplest transition to its new size - with high speed, without compromising the accuracy of the re-return of the gaskets and the reliability of the joints, without the use of fasteners.
