Description

DETAILED DESCRIPTION OF THE INVENTION The present invention opens and closes water supply pipes and water passage pipes by floating and sinking a float in an airtight water tank, and the lower end of the vent pipe protruding outward from the airtight water tank lowers the water level in the water tank. Water is exposed to the atmosphere due to water drop, and when the water level in the tank reaches a certain level, water is supplied from the water pipe, and an appropriate amount of water is automatically supplied to the drinking water tank at all times. Moreover, the blockage effect of the water supply pipe and the water passage pipe due to the floating and sinking of the float is ensured by the weight of the ball that moves from side to side on the float.

Embodiments of the present invention will be described below with reference to the drawings.

1 is an airtight water storage tank in which the water storage tank la and the lid lb are connected with bolts, 2 is a vertical ventilation pipe that penetrates the bottom plate from inside the airtight water storage tank 1 and projects to the outside, and the trachea 2 has its upper end connected to the airtight water storage tank. Tank 1
It is located in the upper space of the tank, and the lower end has the required length depending on the distance to the water source.

3 is a float, with a horizontal support punch 4 protruding from the right end,
The end of the spindle is rotatably mounted on the shaft 5, and the left end of the float 3 is placed on top.
It can be raised and lowered freely, and a heavy sphere 6 is placed on the top surface of the float 3.
A bracket 10 is fixed such that the right end of the guide tube 7, which is sealed therein, protrudes further to the right from the shaft 5, and a first packing 8 is attached to the upper surface of the support punch 4 of the float 3, and a second packing 9 is attached to the lower surface. is rotatably mounted on 11 shafts.

12 penetrates the lid lb of the airtight water tank 1, and its lower end is the first
This is a water supply pipe fixed so as to reach above the packing 8, and its rear end is connected to the water source pipe 13.

14 is a water pipe whose upper end slightly protrudes into the airtight water tank 1 by penetrating the water tank la directly below the second packing 9; 15 is a ventilation pipe 2 and a shallow drinking water tank located below the ventilation pipe 2; The water pipe 14 connects the upper space of the airtight water tank 1 and the drinking water tank 15 below the water surface.

The present invention has the structure as described above.

Next, the action will be explained. First, make sure that all the water is in the airtight water tank 1 (if there is no water or there is only a small amount of water remaining),
The left end of the float 3 is lowered, and the second packing 9 is attached to the float 3.
The weight of the sphere 6 completely blocks the water pipe 14.

In this state, the lower end of the water supply pipe 12 is closed, and water is supplied into the airtight water storage tank 1. As the amount of water increases, the float 3 gradually rises to the surface, and when it reaches a certain water level, the second packing 9 opens the water pipe 14, and the water flows from the water pipe 14 to the drinking water tank 15.
At the same time as the water is drained, the first packing 8 closes the water supply pipe 12. When the water level in the airtight water tank 1 decreases due to drainage to the drinking water tank 15, the float 3 descends and the second packing 9
closes the water pipe 14, and the first packing 8 closes the water supply pipe 12 to supply water into the airtight water storage tank 1. This action is repeated one after another. When the water level in the drinking water tank 15 rises and the lower end of the ventilation pipe 2 is submerged below the water surface, the ventilation into the water tank 1 through the ventilation pipe 2 is cut off. In this state, the water level in the airtight water tank 1 decreases due to drainage, the float 3 descends, and the second
The packing 9 closes the water pipe 14, and the first packing 8 opens the water supply pipe 12, so that water begins to be stored in the airtight water storage tank 1. Also, in this state, the air inside the water tank 1 is gradually discharged to the outside of the tank through the ventilation pipe 14, and when the inside of the airtight water tank 1 reaches a certain water level due to water supply, the float 3 rises to the surface, and therefore the second
The backing 9 opens the water pipe 14, and at the same time, the first packing 8 closes the water supply pipe 12 to keep the inside of the airtight water tank 1 airtight. At this time, due to the pressure relationship between atmospheric pressure and water pressure, even if the second packing 9 opens, water will not drain from the water pipe 14 (
(See Figure 1). The buoyancy and weight of the float 3 and the weight of the sphere 6 are added to completely block the water supply pipe 12 and the water passage pipe 14 by the first and second packings 8 and 9. In this state, if the livestock drinks water from the water tank 15 and the water level of the tank 15 falls and the lower end of the ventilation pipe 2 is exposed to the atmosphere, the air will flow through the ventilation pipe 2 into the airtight water storage tank 1. The water in the water storage tank 1 is supplied to the drinking water tank 16 through the water pipe 14. When the amount of water in the airtight water tank 1 decreases, the float 3 gradually tilts to the left, the sphere 6 rapidly moves to the left, and the second packing 9 closes the water pipe 14 by utilizing the weight of the float 3 and the sphere 6. Then, the water supply to the drinking water tank 15 is stopped and the water in the airtight water storage tank 1 is waited for to increase. In reality, the float 3 is actuated by slight changes in the water surface of the drinking water tank 15, and water is supplied from the water supply pipe 12 and the water flow pipe 14. In the present invention, as described above, the float is repeatedly and automatically operated to supply water so that the water surface of the drinking water tank 15 is always maintained at a constant water level. As described above, the water supply device of the present invention does not make the inside of the airtight water tank airtight while water is being supplied from the water supply pipe, regardless of the water level in the drinking water tank, and the water tank and the airtight water storage tank are not airtight. Since the airtight water tank is constructed to be airtight when the water level inside reaches a certain level and the first packing closes the water supply pipe, the water level inside the airtight water tank and drinking water tank has reached a certain level. When the water level in the water tank drops and the lower end of the ventilation pipe is exposed to the atmosphere and air enters, water automatically drains into the water tank, and the lower end of the ventilation pipe sinks below the water surface and the amount of water discharged increases. The same amount of water is supplied from the water supply pipe to form an airtight system again, and only the necessary amount of water is supplied, making it economical, sanitary, and requiring only a small amount of water to fill up.

Also, when the water level in the airtight water tank decreases and water is being supplied from the water supply pipe, the airtightness inside the airtight water tank is released, so the second
The water pipe is blocked with packing, and water is stored in the water pipe until the water level in the airtight water storage tank reaches a certain level, thereby preventing drainage. However, at a certain time, the rapidly moving weight of the balls can completely block water supply pipes and water pipes to prevent flooding, and can also be used for cattle, horses, pigs, and other pets.
