Description

The present invention relates to an instrument for constructing a Marriott container that can be suitably used for automatic water supply of potted plants and the like, and a drainage pipe for an automatic water supply system.

The Mariotte's bottle (also called the Mariotte's bottle) has the function of supplying water at a constant water pressure from the drainage pipe or drainage port attached to the closed water storage container, and has the function of supplying water with a constant water pressure, and has the conventional soil permeability (water permeation rate). For a method that can be used for measurement (see Patent Document 1) and a method for stably infiltrating water into the soil from a water replenisher in the soil as a water dispenser for potted plants (see Patent Document 2 and Patent Document 3). It is known to be available. In addition, as a simple method for stably supplying water to potted plants, for example, an airtight water storage container is installed upside down in a water replenishment container that allows water accumulated through a porous body or minute pores to gradually permeate into the soil. However, a method of keeping the water level of the refill container constant (see Patent Document 4) is known.

However, if the method provided by the above technology is used to automatically and stably supply water to various plants that have already been potted during a long absence on a trip, etc., an automatic water dispenser is required for each potted plant. Even if you have to install a water replenisher in the soil that has already been potted, or if you try to supply water from one automatic water dispenser to potted plants of different heights at the same time, the water supply height and water supply pressure to the refill container are all. It became the same, and there was a problem that various restrictions and labor were required, such as being unable to adjust to individual potted plants.

An embodiment of the present invention in which water is supplied at the same time by the siphon action of the drainage pipe is shown.

In Fig. 5, the siphon action of three drain pipes to the water replenishment containers installed in three potted plants of the same shape at the same time leaves a gap in the through pipe of the airtight water storage container for water supply while leaving a gap for the water surface to communicate with the atmosphere. An embodiment of the present invention is shown in which a drain pipe of a closed water storage container is inserted and installed to increase the amount of water that can be supplied to the refill container by the siphon action of the drain pipe. Adjust so that the height of the water supply to the water replenishment container installed in the potted plant does not change, and the opening at the end of the through pipe of the two sealed water storage containers is the same in water. ing.

In FIG. 6, a stopper-like sealing body (rubber stopper) is formed by partially folding back the upper part of a stretchable rubber tube made of natural rubber having a thickness of about 1 mm and having an inner diameter substantially the same as the outer diameter of an acrylic through tube 4 having an outer diameter of 16 mm. In the device of the present invention used as 11), an embodiment before inserting and installing a drain pipe is shown, and a through pipe is inserted into an opening 2 of a closed water storage container 1 using a PET bottle containing water 6 and having a capacity of about 2 L. When 4 is attached, the opening 7b opened on the side surface of the tube slightly above the opening 7a at the end of the through tube in water is potted at the highest position among the potted plants having different shapes to be supplied.

The number of turns of the elastic rubber pipe is adjusted according to the size of the gap between the through pipe and the opening of the closed water storage container.

In FIG. 7, three vinyl drain pipes 9 having an inner diameter of 2 mm are inserted and installed in the through pipe of FIG. 6 while leaving a gap through which the water surface in the through pipe communicates with the atmosphere, and a cylindrical portion installed at the tip of the drain pipe. The amount of water sucked and stored in the polypropylene water pressure adjusting cylinder 12 having an inner diameter of 13 mm, a total length of about 50 mm, and a hole diameter of about 1 mm at the tip is adjusted, and three drain pipes are used for three differently shaped potted plants. An embodiment of the present invention in which water is supplied at the same time by a siphon action is shown. Pumping the water pressure adjustment cylinder (partially crushes the air inside to discharge from the tip of the cylinder, closes the tip of the cylinder to release the crush, and sucks the water in the airtight water storage container into the water pressure adjustment cylinder) However, each water pressure is visually confirmed to be the difference between the water supply height to the water replenishment container installed at the highest position in the water pressure adjustment cylinder and the water supply height to the water replenishment container installed in the potted plant. The amount of water stored by pumping into the adjusting cylinder is adjusted. It is possible to change the water supply height to the refill container by changing the dripping height of water in the water pressure adjusting cylinder, and it is possible to change the refill speed of the refill container. It is also possible to change the dripping height of water in the water pressure adjusting cylinder by changing the inclination of the water pressure adjusting cylinder.

As shown in FIG. 7, the refilling container may have a structure separated from the tip of the water pressure adjusting cylinder, or may be attached to the tip of the water pressure adjusting cylinder, and the refilling container may be attached to the tip of the water pressure adjusting cylinder. It may be in a state where it is in close contact with the entire circumference of the water pressure adjusting cylinder without any gap.

In the present invention, since the siphon action is used for drainage, the degree of decompression becomes higher toward the upper part of the drainage pipe, and when a water pressure adjusting cylinder is attached in the middle of the drainage pipe like a general drip cylinder attached to a pressurized pipe. Even if the water pressure adjustment pipe is pumped, a large amount of air remains in the drainage pipe downstream, so it is not easy to express the siphon action, and the water pressure is forcibly adjusted from the tip of the drainage pipe using a separate suction device or the like. When trying to fill the drainage pipe downstream of the cylinder with water, it is not easy to drip water in the water pressure adjustment pipe or leave an appropriate amount of air that determines the flow height in the water pressure adjustment pipe, so the water pressure adjustment pipe is a drainage pipe. It is preferable to provide it near the tip of the.

The most preferable mounting position of the water pressure adjusting cylinder is a position where the drainage pipe opening portion in the upper part of the water pressure adjusting cylinder becomes atmospheric pressure or higher, and in FIG. 7, the drainage pipe opening portion in the upper part of the water pressure adjusting cylinder is a 7b opening portion. It is a position that is below the height.

Set the water level at the highest position among the water-cultivated plants with different shapes to be supplied. Adjust the position of the through pipe so that it is at the height of the water surface of the container of the water-cultivated plant, and put the container of another water-cultivated plant in the container. Insert a silicon drain pipe with an inner diameter of 3 mm to supply water to the water pressure of propylene with an inner diameter of 17 mm, a total length of about 60 mm, and a hole diameter of about 1.5 mm at the tip of the cylindrical part installed near the tip of the drain pipe. The amount of water that is sucked into and stored in each water pressure adjusting cylinder is adjusted so that the dripping height of the water in the cylinder 12 becomes the height difference of the water surface of the container of the water-cultivated plant entering and exiting the drain pipe.

In FIG. 9, an acrylic through pipe 3 having an outer diameter of 20 mm is inserted from an opening 2 having a diameter of about 22 mm in a glass sealed water storage container 1 of about 0.7 L containing water 6 to just before the bottom surface of the water storage container. A stretchable rubber tube made of natural rubber with an inner diameter of about 16 mm and a thickness of about 1 mm is used as a cap-shaped sealant (rubber cap 13) and is closely covered over both the through tube and the opening of the water storage container. An embodiment of the present invention is shown in which the water storage container itself of the Marriott container, which is constructed by inserting and installing a silicon drain pipe 9 having an inner diameter of 4 mm, is used as a vase for flowers and trees. The upper part of the elastic rubber tube is partially folded back to improve the adhesion with the through tube. The through pipe has an opening portion 7b on the side surface of the through pipe slightly above the opening portion 7a at the end of the pipe in water, and when the water level in the through pipe is lowered due to drainage by the drain pipe, the opening on the side surface of the through pipe is made. It is possible to suck the outside air into the water storage container from the portion 7b and hold the water level in the through pipe at the height of the opening portion 7b, and stop the drainage by fitting the cap 14 attached to the outlet of the drain pipe. After that, the above water level can be maintained against the consumption of water by flowers and trees. It can be suitably used for flowers and trees whose stems are easily damaged by water, and the drain pipe 9 can be removed when it is not needed.

The present invention can be used to provide a simple method for stably and automatically supplying water for a long period of time to various plants that have already been potted by using a simple device.
