(57) Abstract:

Use: agricultural irrigation technique to hold the aerostatic aircraft over the irrigated field. The inventive system air irrigation contains aerostatic aircraft 1, the sliding anchor 2, holding the rope, vertical rope, rope pullups 7, the tank 10 to the water and the spray device, rope start and overlapping water performs the function of vertical rope. Aerostatically aircraft 1, which is connected simultaneously with the centre retaining 3 and the end of the pull-up 7 cables, reduces or increases the height of the center of the restraint cable 3, adjusting his angle and thereby the rate of irrigation. When approaching the ends of the cables to the unit pullups 9 is the blocking of water flow and vertical rope participles at the beginning of the next restraint cable 3. 1 C. p. F.-ly, 4 Il.

The invention relates to agricultural irrigation technique and is intended to hold the moving aerostatic aircraft ALA over the irrigated field. This system is applicable in arid areas, where there are small and scattered ponds, Rotello water supply facilities are great.

Known air irrigation system.with. N 1710444), consisting of two stationary ropes, fixed anchors, and equity rope by which water moves aircraft. Share the cable with the aircraft moves at a regular width or to the desired length. In such a system, the ALA, in addition to water tanks and irrigation devices must be constantly working power plant. Moreover, from the beginning of the movement until the middle of the equity rope ALA does not need energy costs, as well as can move at the expense of increasing the lifting force, and in the second half, when the lifting force is increased, and the apparatus should be reduced. Energy consumption increases as the reduction and overcoming the frictional forces retaining ring on the equity rope.

The invention consists in the fact that ALA has no power installation for horizontal movement during irrigation, and there is no cockpit. To solve this task we use two ropes, each length greater than the length between its endpoints fixed on the ground. Filled with water ALA leads watering from the beginning to the middle of the restraint cable. The driving force for ascending the ALA Dina pulled to the surface of the field and participnats at the beginning of the second rope and watering continues. The first cable is removed from the anchor and moved to a new position, and the initial end near the center of the second cable, the future direction of which is arbitrary. The power plant on earth works only at the moment of pull-UPS, and after pereshchepine at the beginning of the next cable is moved to its middle and secured.

Apart tanks with water at the desired points and respectively having direction watering, fix two cable anchors, which may be of different lengths. The length of each cable is larger than the distance between its endpoints fixed on the ground. Filled with water ALA leads watering from the beginning to the middle of the restraint cable. The pulley located at the end of the vertical cable from ALA and peremeshivayte by holding the cable by releasing the spring sotovuyu the latch on the front of the middle of the retaining wire and breaking it along the way can not move in the opposite direction, although it is insuring. At this point, ALA pulled unit consisting of a small motor, gears and winches attached to the ground by a sliding anchor. All the block design lightweight, which is achieved by selection of the transmission mechanism, easy operation the multi-clamping device, fixed to the center of the restraint cable. This same point is ALA2the capacity in which a few pounds and is used for lifting and lowering of the center restraining rope.

The motor is switched on before pulling on and off after pereshchepine at the beginning of the next rope. The duration of a few minutes. Pulling up is offset during irrigation. The offset is equal to the difference between the length of half the restraint cable and the corresponding half of the distance on the ground. Conveniently it from the other side, that there is no effort to move ALA ago; waterer in block pull-UPS, is not in the water. When the end of the vertical rope reaches the holding unit, and ALA will be back in the side for another rope, combined with vertical overlaps the release of water from irrigation tanks ALA. After pereshchepine block is moved to the new place of pull-UPS, and to facilitate moving to it is attached the AL2. Place the new mount is determined by the mark on the middle rope, when he is in position parallel to the earth's surface or lying on it.

ALA can simultaneously horizontal movement ALA, leading irrigation, increasing or decreasing, respectively, the elevation angle of the ascending half of the cable used in irrigation. This system allows you to elect at any time desired direction of irrigation. For example, around ravines, trees and other obstacles. You can Orient it to the wind direction. Direction you can elect with respect to stationary sources of water feeding.

If you have a large number of cables can be put in the right places and directions, and to transfer a block of pullups. Watering can be done and if there is only one cable and three anchors. The essence remains the same. ALA is moving and watering until the middle rope, and then lifted the block. Vertical rope is detached from the holding rope and secured to the anchor blocks. The rope is pulled in the right direction, one end attached to the anchor at block pull. In the future it will continue watering. In this case, there is a pause associated with the permutation of the rope, and ALA at this time watering does not. This system allows high aspect ratio to use irrigated area under the crop.

On ALA no power plants and the cockpit that allows you to increase the Isen its size, and with it costs. Irrigation using non-motorized ALA low because fuel is consumed in a matter of minutes when pulling up, as well as environmentally friendly.

In Fig.1 shows the side view of aerostatic aircraft, leading irrigation; at the beginning of irrigation, the center of the first holding rope and the middle of the second. In Fig.2 in plan shows six positions of the same ALA, and dashed its position before tightening. He is also depicted two adjacent strips irrigation; Fig.3 hinged bracket; Fig.4 filled with the flow of ropes.

Aerostatic aircraft ALA POS.1 of Fig.1, 2, filled with water capacity, combined with a device for spraying 10 starts watering, holding up while ascending half of the cable 3, which in turn is held for land sliding anchor 2. Vertical rope combined with rope overlap and start water 4. Start water spray is made with it in the beginning of the movement, and close when pulling up, when the end reaches the height of the waterer. In front of the center restraining rope is Christmas brake 23, the compressed pulley 5 during irrigation and preventing rearward movement. The end of the vertical cable from the ALA provided with a hinged locking bracket 6 that allows you to join or to remove it from the axis of the pulley 5. ALA28 connected simultaneously with the centre retaining and end of the lifting cables 7 reduces or increases the height of the center restraining rope, adjusting his angle, anago to the ground and connected to the winch 6 and the motor. When the ends of the rope at the overlap of the water approached the block pull-UPS, and a jet of water did not reach it, the water in the spray overlaps and watering stops. When you reach the end of the vertical rope 4 level at the beginning of the next restraint rope hinged bracket 6 is removed, and the center of the first cable is released. Vertical rope 4 participles at the beginning of the second holding rope. Stretching is carried out from the center of the cable C-21, located at the highest point during irrigation in C1-22 and the result is a lower end of the vertical rope not only height, but also on the surface of the field.
