Description

FIELD OF THE INVENTION

The invention relates to agriculture, in particular to the device of pens for keeping farm animals.

State of the art

Known corral for livestock, enclosed by free-standing volumetric blocks, assembled on a flat lattice internal and external shields and frame transverse elements interconnected by sleeve-rod hinges (see patent for invention RU No. 2053657). The disadvantages are the complexity and complexity of manufacturing structures, their assembly into blocks, disassembly and transportation to a new place, and the rather large weight of the blocks.

Known block enclosure for keeping farm animals (see patent for invention RU No. 2668578), made hollow from a flexible waterproof material, filled with air with excess pressure in the form of a rectangular trapezoid, equipped with a nipple valve and a closing outlet (pneumatic unit). The disadvantage of such fencing blocks is the limited length of the block and the need to install a large number of blocks to organize a shelter for keeping animals. This block is the closest technical solution to the claimed object.

Disclosure of invention

Various pneumatic (inflatable) products are known: air mattresses, inflatable boats, inflatable pools, inflatable elements of various designs and even whole inflatable structures having many advantages, the main of which are lightness, high elasticity, speed of installation at a relatively low cost (http: / /pereosnastka.ru/articles/pnevmaticheskie-konstruktsii).

The most common for pneumatic structures are fabric materials, rubberized or coated with polymers. High-strength single and double synthetic films with an internal reinforcing layer of synthetic fibers are also used. According to current standards - СН 497-77 (Appendix 1, table 4) the weight of one square meter of water- and air-tight material used in air-bearing coatings ranges from 0.43 kg (U-93) to 0.80 kg (A-01 ) The connection of sheets of these materials into a structural element is carried out mainly by welding, although their bonding is possible. These are high-strength materials, they work when inflating as gently sloping shells with high calculated resistance, both on the base and on the weft (from 800 kgf / m and above), from which various kinds of inflatable systems can be cut and welded. Including such as pneumatic units, suitable for the installation of enclosures for animal pens. An excess pressure is created in the pneumatic unit, forming its geometry, the value of which can vary depending on the strength of the material (at joints with equal strength with the material). According to paragraph 3.24 of the norms of SN 497-77, to ensure stability with respect to the proposed pneumatic unit, the minimum air pressure inside should be taken at least 15 kgf / m ² (about 0.015 atm).

The essence of the invention is to create such a design of an inflatable unit (pneumatic unit), when the enclosure fence can be organized using a minimum number of blocks. The proposed pneumatic unit should first of all be more extended than the prototype and more compact during transportation. That is, the pneumatic unit should have a cross-sectional shape such that it would be possible to roll the shell of the pneumatic unit into a roll, it should be equipped with elements that allow it to be filled with air as well as released from the air, as well as elements that allow connecting the blocks together and ground. If you imagine a cylindrical pneumoblock with a diameter of 1 m, then 1 ppm of a pneumoblock made from the materials mentioned above will weigh on average about 2 kg. The length of such a block of 50 m will weigh about 100 kg. The block of elliptical cross section with diameters of 1.5 m and 0.5 m will weigh about the same. Thus, we formulate the organization of the device of the pneumoblock.

The enclosure block for keeping farm animals is hollow from a flexible airtight material - a pneumatic block filled with excess pressure air, equipped with a nipple valve and a closing outlet, flexible eyes are fixed to the surfaces of the pneumatic block, which are able to temporarily fix each block to the ground with L-shaped anchors , the block itself has a circular or elliptical cross section, and the initial and final parts of the block are “flattened” vertically and equipped with enes holes to connect between the blocks.

Pneumatic blocks of round or elliptical cross-section are technologically advanced to manufacture, lightweight, easy to assemble and dismantle. The main advantage of such pneumatic units is their long length. Without air, they roll into rolls and transported by vehicle to the place of use. The roll is rolled out, its position is fixed on the ground by partial fastening with anchors on one side, after which it is filled with air and finally fixed with anchors. The pneumatic block of elliptical cross section at the same material flow rate will be higher than the pneumatic block of circular cross section. From these blocks are formed pens of any size and configuration and can be used for livestock.

The implementation of the invention

The enclosure block for keeping farm animals 1 (Fig. 1) is made of a hollow round 2 (Fig. 2) or elliptical 3 (Fig. 3) cross-section of flexible airtight material - a pneumoblock, filled with air with excess pressure P, equipped with a nipple valve ( not shown) and a closing outlet (not shown), flexible eyes 4 are fixed to the surfaces of the pneumatic block, made with the possibility of temporarily securing each block with the ground with L-shaped anchors 5, the initial and final parts of the block fully vertical and equipped with holes 6 with the possibility of connecting the blocks together, for example, a cord 7.

The construction of the pen 8 from the pneumoblock 1 (Fig. 1) is carried out in this way. The pneumatic unit is transported to the construction site in roll form (Fig. 7) in a deflated state. At the first stage, the pneumatic blocks in the deflated state are rolled out along the closed perimeter of the corral, connected by a cord 7 with flattened overlap parts (Fig. 5, Fig. 6) and their position on the ground is fixed by anchors 5, hammered through the eyes 4 from the inside of the corral except for the junction part of two pneumoblocks where animals are supposed to enter. Anchors can be made of both steel and durable carbon fiber. At the second stage, through the nipple valve (not shown), when controlling the change in pressure inside the unit, it is filled with air using an air pump or using compressed air. The change in internal pressure can be controlled instrumentally or more roughly visually by the magnitude of the deformation of the surface of the block (depending on the material used). After that, anchors are installed along the outer perimeter of the corral. If necessary, in the zone of input (output) of animals, the external anchors are removed from the ground, the joint is lined up and part of the pneumatic unit is turned to the outside.

Dismantling a corral from pneumatic units and preparing it for transportation to another place begins with air removal by opening an outlet (not shown) and then in the reverse order of its assembly.

The proposed pneumatic blocks are technological in manufacture. The construction of the corral from substantially elongated pneumatic units is much faster than the construction of the corral of their individual elements. The unconventional cross-sectional shape of the blocks allows them to be rolled up and stacked compactly in a vehicle. Blocks are easily repaired and can be standardized (typed) for each type of animal.
