In general, reasonable water management of rice depends on the local weather conditions, varieties of rice, germination, seeding season, soil and water conditions, and farmer's skill level. The level of discussion should vary according to various circumstances, such as when eggs are seeded before seeding, to prevent deterioration of the roots and to promote growth.

In the water management, the waterway usually formed next to the discussion, the user directly opens the floodgates in accordance with various situations as described above, supplies the appropriate amount of water, and waits for the time being supplied. It takes a primitive way to shut off the water supply by closing the water gate that was opened when the water is full, and the conventional water management method directly opens and closes the water if necessary while the water is continuously flowing along the waterway. In the rice paddies at the bottom of the channel, there is a shortage of water because the water is too much to be lost and most of the paddy fields need to be opened at a time when there is a large amount of water in the rice paddies. The phenomenon occurred.

In the areas where rice field maintenance projects are being promoted recently, pipelines have been used to eliminate ills, such as water shortages, which can minimize water loss and easily supply water to a wide range of areas. It is preferred because it can maintain a constant pressure, the end of the water is installed by the normal opening and closing valve in the end of the rice paddy users to open and close the valve arbitrarily to use the water.

However, the water shortage phenomenon can be somewhat resolved by reducing the loss of water in supplying and indexing water using the on / off valve installed in the waterway as described above. However, a lot of time and manpower is required for proper water management for crops.

As the diaphragm cover 12 and the flexible diaphragm 13 having the through holes 11 formed thereon are sequentially inserted and screwed and coupled, a space having a predetermined size between the upper body 20 and the diaphragm 12. An operating chamber 16 having a shape is formed, and a discharge port 31 is formed at one side of the lower portion 30 so that the elbow 32 for water induction is coupled and a filter assembly is fitted at the other side thereof. And the air pump 50 is installed to communicate with the interior.

At this time, the air pump 50 installed in the lower body 30 together with the hose assembly 70 is an air inlet 22 and a hose (drawings) penetrated through the upper body 20 so as to communicate with the operation chamber 16. Not shown).

In addition, the upper body 20 is provided with a switching valve switch 40 by the support frame 21, a plurality of through-holes formed in the lower side of the middle side of the switching valve switch 40 by the hose level sensor ( 60).

Figure 4 is a partial cross-sectional perspective view showing a water level sensor of the automatic water supply device for water pipes according to the present invention, the water level sensor 60 is a bracket 63 is rolled on the inner upper portion of the case 62, so that the rear A plurality of hose connecting holes 64 and 65 are formed above and below, and a hydraulic solenoid valve 69 is installed by the bracket 63 to open and close the discharge hole 66 at the lower portion of the hinge shaft 67. An end portion 77 is installed at an end portion so as to be driven up and down by a support rod 72.

At this time, the hinge shaft 67 is driven up and down from the fixed point in accordance with the position of the float 77 according to the water level, the solenoid valve 69 is operated by a hydraulic pressure, which is a known technique because it will be described in detail And drawing notation.

In the drawings, reference numeral 200 denotes a protective box, 102 denotes a farm road, and 103 denotes a drain path.

Referring to the use state of the present invention as follows.

As shown in Figure 1 to Figure 5, the rice field 101 maintenance is completed is already built a system for supplying agricultural water to the pipeline, that is, the irrigation canal 100, the irrigation canal 100 To install the automatic water supply device 1, first, install a protective box 200 having a predetermined area on the upper part of the granular pipe installed at the end of the water pipe 100, the protective box 200 falls or In order to prevent the sinking, in order to make a horizontal state smoothly in advance by laying the gravel or sand in advance and not inclined by the pressure of the soil, the standing pipe and the water hydrant 10 located in the protective box 200 However, at this time, since their connection is made of a flange, residues introduced in the irrigation canal 100 remain, and even if trouble occurs in the water of irrigation water, the discharge of the residues is easy, as well as the water supply 10 To However that would be able to replace.

In this way, when the installation of the standing tube in the protection box 200 is completed, the water level sensor 60 for detecting the upper and lower water level of the discussion is connected to the water supply 10 integrally coupled to the upper end of the lower body (30) At this time, the water level sensor 60 is about 15cm from the ground of the rice field 101, 25cm in diameter to form a hole around the water level sensor 60 to install and fill the periphery of the buried base line outside Match the height of the paddy field (101) and pay attention so that dirt does not flow into the case (62) when filling the surroundings.

At this time, since the water level sensor 60 is integrally coupled to the lower body 30, no space for a separate installation is required.

Therefore, when the installation of the water supply 10 in which the water level detection sensor 60 is integrally completed, the upper and lower water level of the water level detection sensor 60 is set and fixed by the fixing screw 75 and the switching valve switch ( After automatically positioning 40, the main valve (not shown) of the water passage 100 is opened.

As described above, when water flows into the lower body 30 of the water supply 10 along the standing pipe at the end of the water supply passage 100 by opening the main valve, the discharge port (B) by the tube 18 at the lower end of the shaft 17 is formed. 31 is blocked and flows into the operating chamber 16 of the upper body 20 by the air pump 50 via the filter of the hose assembly 70 which is in communication with the lower one side by the pressure of the water.

Therefore, the water introduced into the operating chamber 16 of the upper body 20 is introduced into the valve 69 of the water level sensor 60, and then supplied to the operating chamber 16 to maintain a constant water pressure. Since the solenoid valve 69 opens the discharge hole 66 formed in the lower portion, the hydraulic pressure does not act on the operation chamber 16, and thus the hydraulic pressure acting on the lower body 30 is applied to the shaft 17. ) And pushes the tube 18 fixed thereto so that the diaphragm 13 to which no water pressure is applied is pushed upward to open the flow path of the lower body 30, that is, the discharge port 31. It flows out into the rice field 101 along the discharge port 31 extended to the elbow 32.

As such, when the opening of the discharge port 31 continues for a predetermined time, water accumulates in the paddy field 101, thereby raising the float 77 of the water level sensor 60, thereby causing the hinge shaft ( 67 is driven to close the solenoid valve 69.

As a result, the hydraulic pressure acting on the pipe flows into the operating chamber 16 of the upper body 20 of the water supply 10 through the hose, and expands the operating chamber 16 by the hydraulic pressure of the introduced water. The diaphragm 13 is lowered and the shaft 17 coupled to the diaphragm 13 is simultaneously lowered so that the tube 11 at the end of the shaft 17 closes the outlet 31 of the lower body 30. will be.

Therefore, since the water in the water passage 100 is acting a constant water pressure to the operating chamber 16 via the filter of the hose assembly 70, to prevent the excessive supply of water to the paddy field 101, such as rice It is to maintain a constant level of water supplied to the crop.

In addition, while maintaining the closed state of the discharge port 31, when the water flowing into the paddy is evaporated or leaked, the float 77 of the water level sensor 60 is lowered, the solenoid valve by the hinge shaft (67) As the 69 is driven (opened) and the water pressure is released, the water pressure of the water applied to the granular pipe and the lower body 30 of the water passage 100 pushes the tube 18 of the shaft 17 upwards. Since the discharge port 31 is opened, water is automatically introduced into the paddy field 101.

As such, in automatically supplying the water, foreign substances (dust) mixed in the water introduced through the water pipe 100 may be introduced together to close the filter, but this may be caused by an air pump ( When a predetermined pressure is applied by 50), the water flows back by the water pressure, and foreign substances introduced into and stacked on the filter are removed and discharged into the paddy field 101 through the discharge port 31.

On the other hand, it is possible to manually supply the water level of the paddy field 101 by manually operating the upper and lower water level of the automatic water supply device 1 for the irrigation channel as above, which is the support frame 21 on the upper body 20 By operating the fixed switch valve 40 is fixed to), the user can freely adjust the water supply of water freely, and also, in the front of the discharge port 31 elbow 32 of the water supply (10) separate attachment ( If not connected to the drawing and connected to the hose, it can be applied for irrigation and watering of fields, orchards, houses, etc. If necessary, it can be used for cleaning of various agricultural machinery.

In this way, according to the automatic water supply device for water pipes according to the present invention to automatically perform the opening and closing operation of the water supply device according to the water level set in the water level sensor, the level of discussion can be automatically adjusted to save water and water management Not only is it efficient and economical by reducing labor time and maintenance and management costs, but also by precisely controlling the water management of crops, improving the growth environment of crops, increasing the yield and increasing farm income. Since the water level sensor is integrally combined with the lower body, it is not necessary to secure a separate space when installing the water supply device, so the installation is simple and easy to solve the hassle, thereby making it easier for the worker.
