(57) Abstract:Usage: for subsurface irrigation in terrestrial conditions, on a spaceship, in the greenhouses on the moon. The purpose of the invention is to direct the flow of water from the humidifier into the plant soil near the root system at maximum fillable volume of the body of the pipe. The essence of the invention: pipe-humidifier in the near half of the root system, there are holes on top of the pipe and an angle of 30 and 45° for the passage of water from the body of the sprinkler and the bottom pinned inflatable cylinders. Before filling in the fill water tanks are at the bottom of the humidifier in the released position. As the water fills the casing of the humidifier to the holes, angled 45°, its block, the cylinder begins to build up air. Extending the cylinders displace the water in the direction of the soil near the root system. So the water was forced out evenly along the entire length of the humidifier, the cylinders are selected with different elasticity, which decreases from the beginning to the end. Inflatable balloons are always at the bottom of the humidifier, for which they held the T-shaped protrusion which is inserted through the T-shaped slot opening found on the number of cycles depends on the norms of moisture. After watering the cylinders remain in the pressurized state and fill the entire internal volume of the humidifier, thereby eliminating reverse the penetration of water and silt into the housing. 1 C.p. f-crystals, 5 Il. The invention relates to agriculture and can be used for subsurface irrigation in the spacecraft, the greenhouses on the moon, on earth, when there is a critical shortage of water and irrigated plot horizontal.Known subsurface humidifier containing body with the water outlet holes, which are installed in series and communicated with each other. Inside the units are air chamber formed by the elastic element attached to the inner wall of the housing and communicated with the source of compressed air.The disadvantages of the known subsurface humidifier low water conservation design and the lack of ability protection from siltation.The purpose of the invention is the increased efficiency due to maximum use of the volume of the body of the pipe.The invention consists in that the tube-planites in the near half of the root system, there are holes on the top of the pipe, and that the units by the beginning of the filling of the fill water tanks are at the bottom of the humidifier in the released position. As the water fills the casing of the humidifier to the holes located at 45abouther block, and the cylinder begins to build up air. Extending the cylinders displace the water towards the soil near the root system, overcoming fiberglass permeable to water, but prevent the humidifier from silting in the opposite direction. Part of the water will slide on the outer surface of the housing of the humidifier to the ground, caught in the grain filler, which she capillary way between the underlying waterproof film and through the end of the glass fibre will also rush to the root system. Air injection will be made to fill the inner volume of the housing of the humidifier. Holding out for the T-shaped bracket at the base, expanding the air cylinders are always at the bottom, and the water in the side of the hole to its full displacement. After the necessary pause the air cylinders are manufactured, they are compressed and the process repeats.In Fig. 1 shows two sections of the subsoil of the humidifier with cliffs along the length of Fig. 2 - section a-a in Fig.1; Fig. 3 - the same (the cylinder in a state of total population); in Fig. 4 - node I in Fig.1; Fig. 5 - section a-a in Fig. 1 (onlineplayer consists of buildings 1, have elongated holes 2 located at the top, and an angle of 30 and 45about. Couplings 3 of the housing 1 are combined in the iterative humidifier. Inside 1 placed inflatable chamber 4' in the released position and they are 4, air-filled and stretched to the full internal volume of the housing 1. On the input side of the humidifier includes a cap 5, which is screwed a nozzle 6 for the passage of water into the housing. To connect the cylinders in a single system for all of the waste from them worn nozzles, o-rings 7 with grooves on the profile, similar to the tabs of the socket. Clutch 8 are screwed into a single system connecting cylinders 4, which when the sealing ring 7. At the beginning and end of an inflatable balloon placed the nipple 9 for air release. At the end of the humidifier put the cap 10 with a hole for the pipe with the nipple 9 on the end. The t-shaped slot 11, performed at the inner base of the housing 1, serves for the passage through it of a similar T-shaped projection 12, is made at the base of the container with the possibility of testing more than a solid plate. At the end of the T-shaped protrusion of the container 12 has a mounting hole 13, which is fastened the rope when pulling T-obraznogo humidifier from silting. Under the humidifier falls waterproof film 15 above the fiberglass is laid vegetative ground 16. Arrows 17 shows the path of movement of water through the holes 2 and at the end of the fiberglass. Position 18 marked the boundary wetting, 19 - cultivated plants. Above the surface 20 of the soil are the above-ground parts of plants. In the upper part of the grain filler sinuses 21 dimensions formations more of the cross-section of the holes in the bottom from the base and to the junction of the glass film is smaller and capable of capillary way to direct moisture to the root system of plants. Stable base 22 is made of any material.Before starting the humidifier in the work of the inflatable chambers are compressed 4'. Through the nozzle 6 water enters the casing 1 through the openings 2, angled 45about. The level of housing of the humidifier water can be recorded using the scale located on the stem of the float in the tank, connected with it at the end or the right place. In the absence of subsurface float humidifier will work and if the internal volume will be fully occupied by water. In this case, an increase in Laganside the spirit into the chamber 4, which are stretched equally along the entire length due to the fact that the elasticity in the links they depart from beginning to end. To prevent leakage of air at the end of the pipes from adjacent cylinders worn sealing ring 7 with grooves similar to the protrusions nipples, a tight coupling 8. At the beginning and end of the series of cylinders are placed the nipple 9 for the release of air before watering, and also in one watering between pauses. At the end of the last section is the cap 10 with a hole for the pipe, pull the air through the nipple 9. Inside the housing 1 has a T-shaped slot 11, through which extends the base of the cylinder 12 of the T-shaped profile. Through the hole 13 is attached mounting cable, and it enables the coupling of a T-shaped base 12 with a T-shaped slot 11. The result is an inflatable balloon with a T-shaped base 12 is fixed to the housing subsoil of the humidifier on the opposite side of the holes 2. Before filling in the casing 1 water cylinders for air 4 held the position 4' (Fig.3), and when the air supply completely occupied by the internal volume 4, displacing all the water through the holes 2 (Fig.1, 2 and 5). Water breaking glass, then the capillary method rushed into the soil 16 corpus humidifier 1 to the base, but, not breaking the waterproof film 15 located under the humidifier has been in heterogeneous aggregate sinuses 21, capable of directing the moisture in the soil near the root system of holes that is facilitated by the curved surface of the film. Fiberglass 14, which prevents the humidifier from silting up, moving in the opposite direction, works reliably with a long pause. After watering cylinders 4 should be left in a state of complete air fill the housings 1, which prevents the penetration of sludge inside.Unlike the prototype of the proposed subsurface humidifier ensures the correct direction of water flow and allows maximum use of its volume inside the humidifier. 1.
