Description

The technical field to which the useful product relates

A useful product relates to devices for household drip irrigation using plastic containers with screw caps.

State of the art

The author does not know special devices for household drip irrigation using plastic containers with screw caps that have a small thickness.

A device is known, WO 2008/129310 A1, 10.30.2008, using a plastic bottle for irrigation by entering water directly into the soil.

A device is known, 2409024 C1, 01/10/2011, for drip irrigation (dropper), which can be used with plastic containers, which is much more complex in comparison with the proposed, greater sensitivity to contamination, leading to the termination of the dropper. It is also complicated to remove contaminants to continue watering.

A device is known, RU 2007101057 A, 2008-07-27 and RU 2370946 C2, 2009-10-27, which offers an in-line, disc-shaped drip outlet connected to the inner surface of the irrigation pipe. The device is more difficult to manufacture and operate.

The proposed device is simple to manufacture and operate. Easier to solve the problem of eliminating contaminants that can prevent drip irrigation.

Useful product disclosure

The objective of the useful product is to conduct household drip irrigation using plastic containers with screw caps. This is achieved using a special bolt. A special bolt is screwed into the hole in the screw cap of the container. The structure of the special bolt is such that along the part of the bolt opposite the bolt head there is a channel for water to flow between the bolt and the hole in the cover.

At certain positions of the bolt, water can slowly flow along the bolt, along the channel, between the bolt and cover and, dripping down the bolt drop by drop, reach the soil. By changing the position of the bolt, you can change the transverse area of the channel for water to flow between the bolt and the hole in the lid and thereby change the speed of water flow along the bolt and then change the frequency of droplets falling onto the soil. The ability to change the transverse area of the channel for the flow of water makes it easy to take into account the presence of minor suspensions in the water that can clog the channel, and ensures continued irrigation when the channel is clogged. An increase in the transverse area of the channel for water to flow between the bolt and the hole in the lid allows water to flow past the impurities, and then the flowing water can wash away the impurities.

A special bolt can be used as an emitter in drip irrigation systems using hoses with sufficiently thick walls, 2-3 mm. To do this, special bolts are screwed into the holes made in the hose with the required interval, which is necessary for the diameter bolts, and then watering is carried out as with a screw cap on the bottle. Selling emitters are designed for a fixed rate of water outflow, they are more expensive, they are sensitive to pollution, they require the cost of filtering the water. A special bolt allows you to easily change the speed of water flowing along the bolt and change the frequency of drops falling on the soil. Drops are formed at the actual pressure of the water in the hose at the bolt. If it is possible to produce thin-walled hoses with periodic thickening of the walls of the hoses up to 2-3 mm, at a distance of the water outlet, it would be possible to produce drip irrigation from hoses at the lowest cost.

A special bolt can also replace expensive droppers when watering bushes, trees.

It can be noted that the possible slow flow of water dropwise with a fully screwed bolt, at high water pressures (large containers for irrigation) is functional, that is, it is not a disadvantage of this method of drip irrigation.

Implementation of a useful product

A device for household drip irrigation using a special bolt using plastic containers with screw caps can be implemented as follows.

For drip irrigation, a special bolt of any type is screwed into the hole in the cap (Figure 5-4) of the plastic bottle (Figure 5-5).

A special bolt of both the first (Figures 1, 2) and the second (Figures 3, 4) types can be made of metal or hard plastic. The diameter of the bolt is no more than 3-4 mm, the thread is better with a small pitch, shallow, this will allow to stop water flow well when the bolt is screwed in, when the channel for water leakage (Figures 1-2, 2-2, 3-2, 4-2 5-2, 5-2-2) is out of contact with the outer plane of the screw cap (Figure 5-3).

A special bolt of both the first (Fig. 1, 2) and the second (Fig. 3, 4) types is screwed into the hole in the cap (Figure 5-4) of the plastic bottle (Figure 5-5). The hole can be made in any available way, either using a drill or an awl, followed by flaring the hole to the desired diameter. The diameter of the hole should be such that the special bolt is screwed in tightly and with the bolt screwed in, when the channel (Figure 1-2, 2-2, 3-2, 4-2, 5-2, 5-2-2) for water to flow out out of contact with the outer plane of the screw cap (Figure 5-3), water did not leak.

In that position of the bolt, when the bolt is screwed deep enough and the channel (Figures 1-2, 2-2, 3-2, 4-2, 5-2, 5-2-2) for the flow of water along the bolt is completely out of contact with bottle cap (Figure 5-4), a tight threaded connection prevents water from flowing out of the bottle. When unscrewing the bolt, the beginning of the channel approaches the point of contact of the bolt and the bottle cap (Figure 5-2-2), its narrowest part. When the beginning of the canal (Figure 5-2-2) reaches the outer plane (Figure 5-3) of the screw cap of the bottle, water begins to flow through the beginning of the canal, its narrowest point with minimal speed. The flow rate is determined by the height of the column of water in the bottle (water pressure at the bottle cap) and the size of the bolt. With this position of the bolt, it is possible to receive rarely falling drops. With further unscrewing of the bolt, the outer plane (Figure 5-3) of the screw cap of the bottle reaches the parts of the channel that have a large transverse area (Figure 5-2) for the water to flow, and the water begins to flow at a higher speed. At first it is more often falling drops of water, then it can be a thin stream of water, which depends on the pressure of the water, that is, the height of the bottle. The function of receiving falling drops is performed by the bottleneck of the channel (Figure 5-2-2). Screwing in and out of the bolt allows you to change the transverse area of the channel and thereby control the frequency of drops falling.

Screwing in and out of the bolt also makes it easy to take into account the presence of minor suspensions in the water that can clog the channel, and ensures continued irrigation when the channel is clogged and the ability to control the rate of water outflow. If the transverse area of the channel increases (Figure 5-2-2) for water to flow between the bolt and the hole in the cover, water will be able to flow past the impurities, and then the flowing water can wash out the impurities.

To facilitate the rotation of a special bolt, which is important for its functioning, the bolt has a head with ears, which makes it easy to rotate the bolt if the bolt is possible due to clogging of the channel or pauses (the bolt dries to the lid) when watering. In this case, the function of continuing irrigation when the channel is clogged is performed by parts of the channel with a larger area.

Figure 6 shows another version of the special bolt. At the head, the bolt has a conical shape (Figure 6-1-1), which allows for prolonged use of the bolt to take into account the wear of the hole in the bottle cap, as a result of which the bolt may lose its ability to close the outflow of water in its cylindrical part, and for some time, possibly not small, use a special bolt, closing and opening the outflow of water, using the conical part of the bolt, and use sections of the bolt with a conical shape of a smaller diameter for drip irrigation. Obvious is the ability to use a conical bolt along the entire length.

Figure 7 shows another version of the special bolt. The bolt has a short conical shape when viewed in section (Figure 7-2), the length of the channel is greater than the thickness of the screw cap. Unscrewing and screwing the bolt allows for drip irrigation.

Figure 8 shows another version of the special bolt. The bolt has 3 channels along its entire length (Figure 8-2), each longer than the thickness of the screw cap (Figure 5-4). The presence of more than one channel makes it possible to better overcome clogging of the bolt channel by unscrewing the bolt to the next channel in the water and free from clogging or screwing it to the next channel in the air and free from clogging.
