Description

Automatic control device for valley water providing of small water supply}

The present invention automatically stops the supply of valley water to the water tank in any case until the disinfected water stored in the water tank of the liver abnormality is exhausted, and the water tank is at the lowest level (the time of exhausting the disinfected water). When it reaches), it belongs to the technical field that automatically controls the valley water supply of the Gansang water supply system to automatically resume the valley water supply.

In general, the islands and Domesan Valley where water supply is not spread are operated by the village or regional unit by themselves. Most of these islands have water tanks installed in high places such as the mountain slopes, Buried a pipe underground to the point and run the motor pump to pull up the groundwater and store it in the water tank or store the natural valley water flowing along the valley without using the motor pump in the water tank and supply it to Kagaho Lake. There is a situation.

However, most of the above-mentioned water supply facilities are not easy to access because they are installed in the mountainous backcountry, and the management was difficult because the site manager was selected as a non-specialist villager.

In particular, in order to use the liver abnormal water as drinking water, even if the sterilizing agent must be put into the water supplied to the water tank to eradicate various germs, the manager cannot visit the bar periodically at regular intervals using a disinfectant injector. Disinfectant is being injected automatically.

In the case of liver abnormality in which the above disinfectant injector is applied, the disinfected water decreases as the concentration of the disinfectant decreases over time (2 to 3 days), but once the disinfected water is consumed until the concentration decreases, conventionally In the absence of this consumption, new water and disinfectants are supplied immediately, which means that the villagers consume the dilution of the old and the disinfected water.

Therefore, the existing disinfected water is lost in the concentration of disinfectant completely by staying in the water tank for a long time, and eventually the villagers are drinking the water that has not been disinfected.

In order to solve such a problem, "patent registration No. 757039 named valley number automatic control device capable of precise adjustment" has been proposed by the applicant of the present invention and granted a patent registration.

However, the above-described pre-registered invention obviously provides a useful effect, but the overall structure is rather complicated, and the related parts are coarse, and it is rather difficult to build a mass production system.

The present invention is to actively solve some of the improvements of the above-described pre-registration invention, the float bar that is operating in the upper rotation when the water tank reaches the highest level of the first ratchet to prevent the reverse rotation of the bi-directional gear By releasing the ratchet state of the valve, the valve operating bar rotates upwards to automatically shut off the flow path to the water tank, and when the water tank reaches the minimum level, the float bar that rotates downward prevents reverse rotation of the bidirectional gear. The object of the present invention is to release the ratchet state of the second ratchet so as to automatically open the flow path toward the water tank while the valve operation bar rotates downward.

The present invention connects the inlet pipe and the overflow pipe to the upper and lower sides of the three-way ball valve coupled to the front end of the water pipe as a means for solving the above problems, the ball top device and the bidirectional to the valve shaft of the three-way ball valve Gears are integrally connected to each other, and a pair of first and second ratchets are rotatably installed on both sides of the upper side of the bidirectional gear to prevent the reverse rotation of the bidirectional gear, respectively. According to the rotation of the float bar is installed freely fitted to the float bar coupled to rotate up and down, and according to the swing operation of the float bar to selectively release the ratchet state by pushing the first ratchet or the second ratchet outward Develop a technique for installing the ratchet release mechanism integrally.

According to the present invention, the three-way ball valve directed to the water tank only when the water tank reaches the highest level, the flow path to the water tank is blocked and at the same time the overflow pipe is opened to store not only a sufficient amount of water in the water tank but also continue to supply The water to be provided provides the effect of smoothly draining to the outside through the overflow pipe.

In addition, the three-way ball valve continues to block the flow path to the water tank until the concentration of the sterilized water is consumed before the concentration of the sterilized water is lowered. The sanitary water it maintains will be available for residents to drink.

In addition, as the overall structure of the valley water supply control device is simple, and individual components are simple, assembly production is easy, productivity is excellent, and mass production system is provided.

It will be described a preferred embodiment for implementing the solution of the problem to be solved by the present invention in more detail.

Hereinafter, the present invention made of the schematic configuration will be described in more detail.

First of all, the water pipe 2 of the present invention serves to supply groundwater or valley water to the inside of the water tank 1 by being connected to the inside of the water tank 1 from the outside. One end of the three-way ball valve 10 is coupled to the front end, the disinfectant injector to supply water to the water tank (1) or installed inside the water tank (1) above and below each of the three-way ball valve (10) An inlet pipe 3 for supplying water to the overflow pipe 4 and an overflow pipe 4 for inducing and discharging water after filling the water tank 1 are connected.

Therefore, the water in the water pipe (2) is guided to the inlet pipe (3) or overflow pipe (4), while the direction of the flow path is selectively switched in accordance with the operation of the rotary ball installed in the three-way ball valve 10, Can be discharged.

The ball top device 20 is organically grafted to the valve shaft 11 of the three-way ball valve 10, and the ball top device 20 is composed of a valve operation period 21 and a buoyancy body 22. The valve operation section 21 is integrally attached to the outside of the valve shaft 11 in a fitted state, and the buoyancy body 22 is installed at the lower end of the valve operation section 21 to provide the valve operation section 21. In accordance with the up and down swing operation of the valve shaft 11 and the reverse rotation at the same time it is possible to selectively control the flow path of the three-way ball valve (10).

However, the balltop device 20 does not immediately operate up and down according to the water level change in the water tank 1 even though the buoyancy body 22 is provided, and the float 51 of the present invention reaches the highest water level or the lowest water level. Only when it reaches the moment it works up and down momentarily. Therefore, until the water level of the water tank 1 reaches the set minimum water level, the valley water supply is stopped after the valley water supply is reached, and the valley water supply is resumed, and the water level of the water tank 1 is set to the highest water level. When it reaches, it can automatically stop the valley water supply.

In order to enable this, the two-way gear 30 is integrally attached to the front side of the valve operation section 21 in a state where the bidirectional gear 30 is fitted to the outside of the valve shaft 11 continuously in front of the valve operation section 21. do.

In addition, a pair of first and second ratchets 40 and 40a is hinged to the base plate 35 attached to the front surface 10a of the three-way ball valve 10 on both upper sides of the bidirectional gear 30. The first and second ratchets 40 are installed to be symmetrically facing each other so as to penetrate through the first and second rollers 42 and 40, respectively, before and after the first and second ratchets 40 and 40a. 40a is smoothly rotated and the lower end of the first and second ratchets 40 and 40a is fitted into the ratchet groove 32 of the bidirectional gear 30 while the bidirectional gear 30 is in one direction. Ratchet protrusion 43 to prevent the reverse rotation to the protrusion is formed.

That is, as shown in FIG. 8, the first ratchet 40 prevents the bidirectional gear 30 from rotating in the right direction in the drawing so that the ratchet state of the first ratchet 40 is not released unless the ratchet state of the first ratchet 40 is released. Cannot pivot upward, and the ratchet state of the second ratchet 40a is not released by preventing the bidirectional gear 30 from rotating in the left direction as shown in FIG. 10. The abnormal valve operation period 21 cannot be turned downward.

On the other hand, unlike the valve operation period 21 is integrally coupled to the valve shaft 11 to rotate in conjunction with the valve shaft 11, the float bar 50 is rotated in a state spaced apart from the bi-directional gear 30 It is fitted freely coupled, the float 51 is installed below the float bar 50 to move the float bar 50 up and down while moving up and down by buoyancy according to the water level change.

At this time, the float bar 50 is attached to one side of the float bar 50 protruding integrally projecting to one side of the float bar 50 to limit the excessive movement in the swing operation up and down according to the water level change of the water tank (1) In addition, the locking protrusion 52 is selectively restricted to a pair of stoppers 53 and 53a attached to the base plate 35 located on the upper and right sides of the bidirectional gear 30 as a starting point.

The float bar 50 is a ratchet release tool 60 to which the ratchet release mechanism 60 forcibly releasing the ratchet state of the first and second ratchets 40 and 40a is integrally attached to the upper rear face. ) Temporarily moves the first ratchet 40 or the second ratchet 40a to the outside while moving left and right according to the swinging operation of the float bar 50 to temporarily release the ratchet state, thereby actuating the valve 21. This buoyancy or gravity makes it possible to operate up and down.

In the present invention having such a configuration, the balltop device 20 cannot operate by itself according to the change in the water level, and the bidirectional gear 30 is connected to the first ratchet 40 when the water tank 1 reaches the minimum water level. By preventing the reverse rotation, even if the water level rises as shown in FIG. 7, the valley water supply is smooth by opening the flow path toward the water inlet pipe 3 while maintaining the fixed state.

When the water level of the water tank 1 reaches the highest level, the ratchet releasing tool 60 of the float bar 50 that is pivoting upward in response to the change of the water level pushes the first ratchet 40 as shown in FIG. 8. At the moment of releasing the ratchet state, the valve operating section 21 rotates upward by the buoyancy force of the buoyancy body 22 to rotate the valve shaft 11 to close the flow path of the water inlet pipe 3 and at the same time overflow By opening the flow path of the pipe 4, the water tank 1 can no longer be oversupplied and can be thrown out through the overflow pipe 4.

Here, the ratchet protrusion 43 is formed on the upper portion of the ratchet protrusion 43 by protruding the ratchet release tool 60 while pushing the ground protrusion 45 while being in close contact with the ground protrusion 45. The ratchet release operation of the second ratchet 40 and 40a is made smoother and more accurate.

In addition, the ball top device 20 of the present invention, when the water level of the water tank 1 reaches the set maximum water level stops the reverse rotation by the second ratchet 40a that the bidirectional gear 30 automatically rotates as shown in FIG. By closing the flow path to the inlet pipe 3 while maintaining the fixed state until the disinfected water in the water tank 1 is consumed (set minimum water level), the disinfectant in the water tank 1 is always uniform in concentration. When the water level of the water tank 1 is reached and the set minimum water level is reached, the ratchet releasing tool 60 of the float bar 50 which is rotated downward in accordance with the water level change is shown in FIG. 11. The ratchet state is released while pushing the ratchet 40a. At this moment, the flow path of the water inlet pipe 3 is instantaneously turned downward by the valve weight between the buoyancy body 22 and the valve actuation 21. Is automatically opened and at the same time the flow path of the overflow pipe 4 is closed. The valley water supply can be resumed.

The present invention indicates the point where the float 51 is located at the bottom of the water tank 1 at the same time and at the same time the maximum amount of use and valley water supply to be used in a state in which the concentration of the sterilized water is not lowered. At the same time.

Therefore, the present invention can control the set value including the lowest water level by freely adjusting the position of the float 51.

In the technical configuration for this, the float bar 50 has a plurality of control holes 71 are formed at equal intervals, the control hole 71 is a plurality of control holes 71 formed in the lowest water level control bar 70 and By being coupled through the coupling member 72 at the same time can adjust the set value of the lowest water level according to the positional change of the lowest water level adjustment bar 70, the lowest water level adjustment bar 70 is attached to the float 51 The fixed bar 74 is installed to be coupled to the upper and lower angle adjustable via the fastening member 72, it is possible to finely adjust the minimum water level according to the minute angle change of the float (51).
