The invention relates to agriculture and can be used for reproduction of rain in laboratory and field conditions.

Known laboratory sprinkler, consisting of sections with vibroblades and pressure pipes with nozzles, with flexible tubes and adapters [1]. The disadvantage of this device is the low uniformity of the distribution of rain on the area of irrigation. The water flowing through the nozzles for flexible tubes, uneven fills them. Those tubes that are filled first, start to suck water from the nozzles, creating in her depression, which does not allow to fill the rest of the tubes, which in turn leads to a great imbalance of the expiry of water between them.

Known laboratory-field sprinkler consisting of a tank, motor, pump, filter, valve, pressure conduit and sprinkler [2]. The sprinkler is made of are fastened to the frame culverts with tees, valves, overflow device and sprinkler nodes. Sprinkler nodes consist of sequentially mounted on the tee washer with nozzle, a nipple, a vertical thick flexible tubing, clamps, sleeves and thin flexible tube with a calibrated sleeves.

Water is supplied through the nozzles in the sprinkler nodes to a thin flexible tube with a calibrated sleeve and and it is distributed over the entire area of sprinkling. The throttle cross section grooved bushing has a small value. Small air bubbles in the water, partially block them. This reason does not allow all thin flexible tube with a calibrated bushings consistently miss the same amount of water and, consequently, to maintain the same intensity over the entire area of sprinkling.

The purpose of the invention is improving the uniformity and stability of the distribution of rain in area with irrigation and simplify the design when working with small experimental sites.

To eliminate these drawbacks and to solve this problem is proposed portable laboratory and field sprinkler, comprising a horizontal frame, vertical racks with hanging bracket, the locking mechanism with a water tank and a lid, the supply and discharge conduits with filter and valve, the float system with rubber and sprinkler with a horizontal panel.

The water tank is made of transparent material with a tightly fitting lid that provides easy monitoring of the water level and timely refilling. It is fixed above the horizontal frame with the panel.

The float mechanism mounted on the penstock. It consists of a collapsible transparent housing with consistently defined therein, the slot of the needle, the needle is, float with the sender, which in the lower part of the body is inserted into the nipple. The float mechanism provides for any amount of water in the tank constant level in the body, hence, a constant intensity of rainfall.

The sprinkler includes sequentially attached to the nipple thick flexible tube with clamps, bushing, and a bundle of thin flexible tubes. In this case a thin flexible tube before mounting the selected bandwidth for water. Preliminary sampling ensures uniform water flow through each of the thin flexible tube that improves the stability of the entire sprinkler installation.

A thin flexible tube upper ends rigidly mounted in the sleeve, and the lower horizontal panel on the spiral of Archimedes so that the distance between adjacent fixing points on the spiral is the same for all sprinkler installation.

Figure 1 shows a portable laboratory and field sprinkler, figure 2 is an enlarged float mechanism, figure 3 - type sprinklers below.

Portable laboratory and field sprinkler (figure 1) consists of a tank 1 with a cover 2, a suspension bracket 3, the vertical posts 4, the fixation mechanisms 5, filter 6, the feed conduit 7, valve 8, pressure conduit 9, the float mechanism 10, a blower 11, the nipple 12, tol is the flexible tube 13 by clamps 14, sleeve 15, a thin flexible tube 16, a frame 17 and the horizontal bar 18 (Fig 3).

The float mechanism 10 (figure 2) with rubber 11 is fixed on the pressure conduit 9. It consists of a collapsible transparent body 19 sequential in its socket needle 20, the needle 21, the float 22, 23 and a leader of the nipple 12. Rubber bulb 11 with a drainage hole 24 on the housing 19 of the float mechanism 10 is fixed to the side through the drain tube 25.

Figure 3 (bottom view) shows the scheme of fixing capreolata all thin flexible tubes 16 in the horizontal bar 18. Fixation is performed in a spiral of Archimedes. The distance between the fixing points of the neighboring thin flexible tubes 16 are equally along the entire length of the spiral.

Portable laboratory and field sprinkler operates as follows. For hanging the bracket 3 (Fig 1) installation posted on the object under study. Open the cover 2 and is filled with water tank 1. Water through the filter 6 is fed into the input conduit 7 to the valve 8. At the beginning of the operation, the valve 8 is opened and water under pressure to the conduit 9 is lowered into the float mechanism 10 (figure 2) to the socket of the needle 20 passes through the aperture and enters the body 19, gradually filling it displaces the air through the drainage tube 25 and the rubber bulb 11 in the drain opening 24. The water level rises, and in the and lifts up the float 22 with needle 21. The needle 21 overlaps the hole 20, and the supply of water is limited. From the housing 19 of the float mechanism 10 water through the cavity in the leader 23 is supplied to the nipple 12. Next, the thick flexible tube 13 (Fig 1) with clamps 14 it is lowered into the sleeve 15 with a thin flexible tube 16. On them under its own weight water comes to capreomycin ends, which are fixed in the horizontal panel 18 (Fig 3) on the frame 17 and the spiral of Archimedes with the same step.

Rapid commissioning of sprinklers operating mode is achieved by overlapping the drain holes 24 (2) finger with simultaneous compression of the rubber bulb 11. In the case 19 of the float mechanism 10 is created excessive pressure, which forcibly pushes through a thin flexible tube 16 water to remove air bubbles.

After the start sprinkling the installation manual attached to the rotational movement around the vertical axis. As it is damping the rotational movement of the sprinkler installation is renewed regularly.

Picking a thin flexible tubes 16 and bandwidth fixation capreolata ends in a spiral of Archimedes with the same step together with the rotational movement around the vertical axis, and the use of float mechanism 10 stabilization of the water level allow you to get high is equal to most distribution of water droplets on the square sprinkling.

The water tank 1 (Fig 1) and the housing 19 of the float mechanism 10 (2) made of a transparent material. This provides visual control over the process of sprinkling and timely refilling of water into the tank 1, while sprinkling.

The intensity of rain in a portable laboratory and field sprinkler. change by moving water tanks 1 (figure 1) on the vertical posts 4 by loosening the fixation mechanisms 5. When reducing the distance between the sleeve 15 and the horizontal panel 18 rain intensity decreases.

Stops the sprinkler overlap of gate 8 or after all the water from the tank 1 float mechanism 10 and the sprinkler.

The set of essential features of the proposed device provides the technical result is uniform and stable artificial sprinkling while simplifying the structure. Sprinkler made of simple elements and available materials, easy, and reliable in operation.

SUBSTANCE: method of evaluating resistance of textile material to light and weather factors involves preparation of the required amount of samples of the material, testing their initial breaking load, fixing them on a stand with an exposing surface which is tilted at an angle of 45° to the horizontal and is directed to the south, exposing the test material to natural light and weather factors on open air for not less than one year and periodically, every one to two months, testing the breaking load of the part of the exposed samples of the material. Relative loss of the breaking load is determined by comparing properties of the exposed samples with non-exposed samples and the kinetic curve of loss of strength over exposure time is plotted. While exposing the samples, the total, direct and scattered energy of solar radiation in MJ/m entering the zone of the samples is measured, recorded and integrated, after which the kinetic curve of accumulation of radiation energy over exposure time is plotted. Using graphic construction, said curve is superimposed with the kinetic curve of loss of breaking load such that the origin and exposure time values coincide and reflect the link between the curve of loss of strength and the amount of accumulated solar radiation energy which is used as the quantitative characteristic of resistance of the textile material to light and weather factors in form of units of the insolation index. To this end, duration of exposure which leads to 35% loss of breaking load of the material is determined and the amount of energy effect of the total solar radiation in MJ/m2 which causes 35% loss of breaking load is determined and resistance of the textile material is calculated in form of units of the insolation index (1 unit=100 MJ/m2).
