The present invention relates to a livestock waterer for supplying water to livestock raised in a livestock barn, and more particularly, to a livestock waterer for supplying cool water in a summer environment while preventing contamination of the water fountain.

In general, a watering stand used in a barn that confines and rears a large number of livestock is placed on one side of the barn and refers to a container that holds water so that the livestock can drink water. . Water is supplied directly to the water supply tank or water can be supplied automatically or semi-automatically by using a water supply facility.

However, there is a problem that the water fountain is subject to contamination, and labor is required for its treatment. In particular, in the case of summer, the temperature of the water inside the water supply tank rises, and microorganisms can easily multiply, thereby causing disease in livestock.

Accordingly, a water supply device for livestock such as Patent Document 1 has been developed. Patent Document 1 intends to provide clean water at a certain temperature to livestock by continuously circulating water from a drinking fountain. However, since the water from the water supply station is continuously circulated, there is a risk that foreign substances from the water supply station may enter the circulation passage. In small cases, continuous management is required, which inevitably places a burden on the livestock barn operator.

On the other hand, the hot climate in summer acts as a stress to livestock, and it is necessary to supply cold water to alleviate this.

At this time, the first connecting pipe 13 and the second connecting pipe 14 may be connected to different positions in the water supply case 11 , and the different water passing through the cooling unit 30 passes through the water supply unit 10 . In a position where the second connection pipe 14 entering into the cooling unit 30 is relatively far from the cooling unit 30 , the first connection pipe 13 flowing into the cooling unit 30 from the water supply unit 10 is relatively connected to the cooling unit 30 . ) can be connected to a position adjacent to each other, and by making the positions different from each other, the temperature of the water W stored in the water supply case 11 is uniform.

The display and operation unit 50 displays the temperature measured by the temperature sensor 19 , can display a set temperature, and the like, and includes an operation button that a user can operate. In conjunction with the control unit 60, the livestock water feeder 1 is controlled.

In one embodiment of the present invention, the water feeder 1 for livestock is water control including a supply valve 70 installed in the supply pipe 18 of the water supply source WS in conjunction with the water level inside the water supply case 11 . part 20 . In this embodiment, the water control unit 20 has a structure that opens or closes the supply valve 70 according to the height of the float, including the float, but is not limited thereto and may be configured to measure the water level electronically. , it may be a configuration that indirectly calculates the water level. Since the structure for opening or closing the supply valve 70 through the buoyancy is widely known (eg, KR 10-0766032, etc.), a detailed description thereof will be omitted.

In the water control unit 20, the opening height of the supply valve 70 of the water control unit 20 is set higher so that at least the bottom surface of the water sink 12 can be submerged in water. . On the other hand, the inner space side end 12f of the water inlet pipe 12a of the water fountain 12 may have a height corresponding to the bottom surface 12b of the water supply station 12, which is the same as the bottom surface 12b, the It means that the end 12f of the water inlet pipe 12a is at a position lower than the opening height of the supply valve 70 of the water control unit 20 . Accordingly, the stored water flows into the water supply station 12 through the water inlet pipe 12a in a state where a part of the water supply station 12 is submerged in water. A separate power is not required for the inflow of water, and water may be introduced through the water inlet pipe 12a due to a pressure difference between the water level in the inner space of the case 11 and the water level inside the water supply stand 12 .

4 and 5 illustrate this aspect well. In the case of FIG. 4, the state in which the water stored inside the water supply case 11 flows into the water supply station 12 in a normal state is shown, and in FIG. It shows the opening height of the supply valve 70 to introduce water from. As shown in FIG. 5 , the height at which the water control unit 20 opens the supply valve 20 to introduce water is higher than the bottom surface 12b of the water supply stand 12 or the end 12f of the water inlet pipe 12a. it can be seen that

An operation of the water dispenser 1 for livestock according to an embodiment of the present invention will be described.

Since the water feeder 1 for livestock having the above-described structure does not have water in it initially, the supply valve 70 connected to the water supply source WS is opened, and water flows into the water supply case 11 inside, and up to a predetermined water level. Water continues to flow in. As water flows in, water flows into the water supply station 12 as well. When the water is sufficiently stored in the water supply case 11, the control unit 60 sends the water from the water supply case 11 to the cooling unit 30 for cooling circulation. The cooling unit 30 cools the water flowing over from the water supply case 11 and then sends it back to the water supply case 11 , and the water stored in the water supply case 11 is cooled by the cooling unit 30 circulation. can When the livestock eats water from the drinking fountain 12, the water level in the water supply station 12 is lowered, and the stored water is introduced by the water inlet pipe 12a, so that the water in the water supply station 12 is maintained at a level corresponding to the stored water. Also, when the water level of the stored water is lowered, the water control unit 20 supplies water from the water supply source WS.

The cooling unit 30 operates the cooling cycle 32 when water flows over from the water supply case 11, the fan 33 is driven to cool the condenser 32b, and the refrigerant flows over the water from the evaporator 32d. to cool

Even when the external temperature rises, a part of the water supply station 12 is immersed in the temperature-controlled water W, so the water collected in the water supply station 12 may have a temperature similar to that of the water stored in the water supply unit case 11, and therefore in summer You can always drink cool water no matter when the livestock drinks water. In addition, since the water inlet pipe 12a is connected to the side surface 12c of the water supply station 12, even if the feed flows into the water supply station 12, it does not flow into the water supply case 11 through the water inlet pipe 12a. It is also possible to separate and clean the water supply tank 12 or the upper surface 11a.

When the livestock water feeder 1 is not used, the water stored in the water supply case 11 may be discharged by opening the drain valve 80 provided at the lower portion of the water supply case 11 .

In the above, the present invention has been described based on one embodiment, but the present invention is not limited to one embodiment and may be implemented with various modifications.
