Description

[Detailed description of the invention] The present invention relates to an automatic watering control device.

Its purpose is to cover the area with grass, moss, and other layer crops.
A very convenient system that detects when the water is dry and sprinkles water on it.
An object of the present invention is to provide a water sprinkling control device.

The outline of the present invention is to detect an increase in drowsiness resistance value due to lack of water using a moisture sensor made of an electrode plate and a water-absorbing fabric to detect the dryness of the ground, generate a hustle in an electronic circuit A, and amplify this.・The micro valve is opened by energizing the solenoid that produces sugar into micropulp through the nochinkuri relay, and at the same time, the opening of the micro valve completely opens the main nozzle, and at the same time, the timer circuit is activated by discharging water to the moisture sensor. The opening is held for a predetermined period of time, and water is sprinkled with a water sprinkler such as a sprinkler.

Traditionally, lawns, moss, etc. tend to wither if they lack moisture, especially in the summer months, when it is necessary to water them several times a day, which is very troublesome and inconvenient because it is not possible to be away from home on a family trip. This is rare in many cases.

As a means to solve this problem, in recent years, for example, 24-hour timers, magnetic valve type water sprinklers, and the like have become commercially available. This allows you to freely set the watering time in 15 minute increments, making it convenient for the time being, but it doesn't matter if it's dry, as it will water regardless of the moisture level on the ground. Furthermore, since the Mt m of this watering device is AC, it is difficult to use outdoors, and since the watering device is operated from an AC source, there are many safety issues. I rarely found one that loaded the i+jif point.

The inventor has conducted extensive research to resolve these issues.
Watering is carried out by notifying the dryness of the ground, and it is safe without using sensory pulp or AC power, and it is extinguishable (
We have achieved the present invention, which uses very little electricity and has a short battery life, making it possible to maintain water sprinkling for a long period of time.

In other words, when a water flow is generated in the pilot tube, the main pulp is automatically released, and water flows from the main hose to the sprinkler for a predetermined period of time. The IU signal is used to open the micro-valve communicating with the pilot tube, and the water flow generated in the micro-valve is released as a small spray toward the moisture sensor, thereby activating the timer circuit. The inventors have invented an automatic water sprinkling control device characterized by comprising: a means for operating the micropulp and keeping the micropulp open for a predetermined period of time to perform water sprinkling from the water sprinkler.

The invention will be explained with reference to figure ut7.

FIG. 1 is a schematic explanatory diagram showing an outline of the apparatus of the present invention.

As shown in this figure, the main pulp (b) is attached to the faucet (a), and the main pulp (b) is connected to the main hose (c) and the top pilot tube (d). For example, a sprinkler (e
)...and a controller (f) is connected to the tip of the pilot tube (d>).

Both the sprinkler (e) and the controller (f) are placed on the ground (a), such as a lawn, which requires watering.

The moisture sensor (←) is emitting water from the bottom of the controller (f), and its lower end is touching the ground.

When this moisture sensor Q) becomes dehydrated due to the dryness of the ground (a), the Byronto tube (a)
), the main pulp (b) is opened, water flows to the main hose (C), and water is sprinkled by the sprinkler (e). The controller (f) is equipped with a timer circuit, and the watering time can be set freely using Kowa 2. :) Water is allowed to flow through the pilot tube (d) for the desired amount of time.

At the same time, the watering frequency can also be varied by adjusting the sensitivity of the moisture sensor, as will be described later.

For example, the following can be used as the device 11, which opens and closes the main pulp (b) depending on the presence or absence of water flow in the pilot tube (cl).

FIG. 2 is a sectional view showing details of one embodiment of the main pulp in the apparatus of the present invention.

As shown in this figure, the main pulp plug (b) installed in the faucet (a) is connected to the installation port (1) and the inlet connected to it (1)
1 chamber (with power, this inlet chamber (2) is separated by the outlet chamber (3) and the tire flamm valve (4).Template 9
The valve is opened and closed by moving the diaphragm valve (41) into and out of contact with the valve seat (5).

A rear chamber (7) is provided on the rear side of the diaphragm valve (4), that is, at a position communicating with the small hole (6) of the diaphragm valve (4), and a branch pipe connection port is provided from the rear chamber (7). (8) comes out.The pilot tube (a) is connected to this branch pipe connection port (8).

On the other hand, a main pipe connection port (9) protrudes from the output 1'' chamber (3), to which a main hose (C) is connected.

Pylon 1 - When water flow occurs in the tube (d), the back chamber (
7) When the tv water pressure decreases, the diaphragm valve (4) moves away from the valve seat (5) by 1 position due to the flow pressure from the inlet chamber (2), and the water flows to the outlet chamber (3) and the main pulp (b). is opened, and on the other hand, when the water flow in the pilot tube (a) is adjusted to the correct size, the back II'
The water pressure in the IJ chamber (7) increases and the water pressure in the inlet chamber (2) and back chamber (7) increases.
) has the same water pressure as the small hole (6), but the water pressure in the output chamber (3) decreases and the diaphragm valve (4)
The pressing force from 7) contacts the valve seat (52) and closes the main pulp (b).

In this way, the presence or absence of water flow in the pilot tube (d) opens and closes the main pulp tube (b), and the sprinkler 6
) watering is controlled.

One of the features of the present invention is that the main pulp (b) is not a solenoid valve, which makes it suitable for safety.

Next, the means for controlling the water flow in the pilot tube (d'l) will be explained.

FIG. 3 is a schematic cross-sectional view showing the moisture sensor used in the device of the present invention and a small sprayer disposed in front of the sensor.

As shown in Figure 1, the moisture sensor (g) protrudes from below the controller (f), and as shown in Figure 3, a small Nuple nozzle also protrudes from below the controller (f). .

This moisture sensor (g) is attached to the glue 1"<electrode plate (1(
A water-absorbent fabric αI) is placed in contact with the water-absorbent fabric αI), and the lower end of this water-absorbent fabric αI) is in contact with the ground ((A)).

This moisture sensor (g) is protected by an integrated cover Oa having a large number of through holes 02.

Incidentally, FIG. 4 is a detailed front view of the +1V plate 00), and shows how the gold-plated electrodes Ob are provided correspondingly in a comb shape.

When the ground ((a) around this moisture sensor (b)) becomes dry, the water-absorbing fabric (11) dries, and the electrical resistance between the electrodes provided on the electrode plate 00 increases, and this resistance value The increase is transmitted to the sensor circuit of the electronic circuit via the lead wire a (4) connected to both terminals thereof, and the micro valve is opened as will be described later.

When this micropulp is released, the small water flow (b) is communicated with a small spray nozzle θυ, and as shown in Figure 3, it becomes a small spray water (c) and is released toward the moisture sensor (b). It is.

This small spray water (c) is applied to the through hole (12
It enters from + and wets the water absorbent fabric Qll.

By wetting this water-absorbing fabric 01), 'IIIf electrode plate 0
The electrical resistance at zero drops significantly, and as described later, this is transmitted to the limit switch via the sensor circuit to confirm the pulp release.The notch relay operates and activates the quemer circuit, which releases the micropulp for a predetermined period of time. The main pulp (b) is also kept open during that time, maintaining the water flow in the tube (d) and watering by the sprinkler (e).

The biggest feature of the present invention is that this moisture sensor (g)
It consists in doing the work of the street. The second is to detect the dryness of the ground surface (a) and start watering, and the second is to confirm that the pulp has been released by getting wet due to the opening of the micropulp, and to operate a timer circuit to maintain this open state for a predetermined period of time.

In addition, even if the water-absorbing fabric (11) of the moisture sensor (b) becomes dirty with dust or other debris, it will be cleaned by this spray water, and the self-cleaning effect of this spray water (c) will always keep the moisture sensor attractive. ) operation will maintain one optimum state.

As a result of various studies conducted by the present inventor, the most suitable water-absorbing fabric 01) is desirably a rayon nonwoven fabric, and by using this, the durability of the moisture sensor (b)) can be dramatically improved. It has improved. For example, a suitable rayon non-woven fabric is a non-woven fabric made of 1.5 denier rayon yarn using NBR as a binder and having a thickness of 0.2 mm and a basis weight of 852/nf.

The VQυ (also known as a small spray nozzle) is designed to emit water in a fan shape, so that a portion of the emitted water is also given to the ground (a) around the water absorption sensor (g). So it's a must. By doing this, the sprinkler
The time when watering and drying in step (e) is almost the same as the time when the water absorbent fabric Qll dries and watering starts.

By adjusting the thickness and quality of this water-absorbing fabric, it is possible to obtain a drying rate suitable for the climatic and soil conditions of the area where the water sprinkler is installed. By doing so, the frequency of watering can be adjusted from as high as 5 to 8 times a day to as low as once every 2 to 3 days, depending on the purpose.

FIG. 5 is an enlarged schematic cross-sectional view showing one embodiment of the micro 7< loop device according to the present invention.゛As shown in this figure, the micropulp device (h) is a combination of micropulp 06) and latching solenoid 07).
This is built into the controller (f) in the figure.

The water flow from the pilot tube (d) in FIG. 1 flows from the inlet hole 08) of the micropulp 00 to the outlet hole 00. A QIJ ring Qυ and this O ring (21
A plunger (a) that goes in and out of ) is provided to open and close this micropulp (16).

This plunger (A) is constantly trying to come off the O-ring (2]) and escape due to the pressure of the spring (C), but this plunger (A) and the solenoid (1)
This is the operating rod (c) that connects the 7+. id a
When it is attached to η, the @hato spring (2) is compressed 11 and the micropulp (16) is in a closed state. When the current generated in the electronic circuit is amplified by the water shortage detection by the moisture sensor (g) mentioned above and the current passes through this latching solenoid (17), this solenoid 0
A reverse magnetic force that instantaneously cancels the magnetic force of the permanent magnet (a) of 7) is generated in this solenoid a, and the above-mentioned operating rod (a)
The magnetic force that was pulling the 0-ring (QI) momentarily becomes extremely small, the drag force of the spring (C) loosens, the plunger (2) comes off the O-ring (QI), and the micropulp αO is released.

As a result of this opening, the water coming out from the outlet hole 09) communicates with the small spray nozzle Q5) described in r4iJ, wets the moisture sensor (b)) as described in 1qff, confirms that the pulp has been released, and activates the timer circuit. This allows the micropulp to remain open for a predetermined period of time. In other words, during this predetermined time, the magnet attracting portion of the latching solenoid aη is separated from the permanent magnet (c), so it is not pulled back against the force of the nupling (c). Then, after a predetermined period of time, the timer circuit is turned on and reversely energizes the sonnoi door aη, generating an electromagnetic force in the opposite direction to that when it is open, and operating l-J.
′ (c) against the spring (2), push the shiblunger (c) into the o-ring 0υ, and make micropulp Oυ.
occlusion is performed.

The '1 force required to open and close this micro-valve device (h) only momentarily energizes the latching solenoid α, and does not energize solenoid 07) during the predetermined period of watering. It is extremely energy-saving, and can be used as a power source from Ichiike (Ichiike) or Kiike (Oiichiyu).
It only needs to be done once every two months, which is one of the major features of the present invention.

FIG. 6 is a block diagram showing the electronic circuit of the device of the present invention.

As shown in this figure, when the sensor circuit (S) detects a dry state using the moisture sensor Q) and activates the latching relay (r), the latching solenoid Q'71 is driven and the micropulp Q61 is opened as described above. Watering will be done. At the same time, the timer circuit (1) is energized and the pulp υi'I release state continues for a set time (5 to 20 minutes). In this case, there is a limit switch (UL), and when the moisture sensor (G) receives water and is exposed to both forces, the sensor circuit (S) senses this state and causes the limit switch (U) to confirm that the HULG is released. Only then does the timer circuit (1) operate the latching relay (r).

After the set time, the latching solenoid (17
) to the timer circuit (from 1+, a current in the opposite direction to the above is j
This causes the solenoid (1) to instantaneously generate an electromagnetic force that pulls in the operating punch (2), thereby causing the plunger (22) of the micropulp (1b) and the O-ring lever (v) to close the valve. In this case, activate the timer circuit (t) or the latching relay (r)' (7) to confirm that the pulp blockage has been performed -61,1 Minotsinch (u) and make the sensor circuit (S) function again. It has become.

As a power source for the electronic circuit of the present invention, for example, DC1
, 4 5-volt dry batteries may be used in the series, or a solar cell may be used, which allows the nickel-cadmium battery to be charged while being used at 5 A (instantaneous). The performance of the watering device in this experiment was as follows: The watering time could be continuously varied between 5 and 20 minutes, and when the lawn was sprayed with water, it was sunny (20"C breeze).
Watering is done 5 times a day/ζ.

The lifespan of the "straight luz" is calculated to be about 6 months when using high-potency manganese and 5III times a day, and 8 to 12 months if rainy weather, cloudy weather, etc. are taken into account. It turned out that it is possible.

In addition, a control panel is provided on the top surface of the controller (f), and a sensitivity adjustment knob and a timer adjustment knob for the moisture sensor (E) are placed there. ), the conditions for watering can be adjusted in various ways, so it is desirable to have a device that can be adjusted to perform watering at a suitable frequency and time using these adjustment knobs.

As described above in detail, the present invention has a control device ft that automatically sprinkles water according to the dry state of the soil, and the opening and closing of the micropulp can be arbitrarily set by the main bar/l'7'' (7). Watering is controlled by opening the sensor for a predetermined period of time, and it is very efficient because it only sprinkles water when there is insufficient moisture.The frequency of watering can be adjusted by adjusting the conditions and sensitivity of the moisture sensor. The product consumption is low and there is no need to change acid oil once every 3 UJ, and it is safe.Furthermore, the self-cleaning effect of the small spray of the moisture sensor ensures normal operation at all times. It is extremely effective for watering lawns, moss, agricultural crops, etc.
