Description

Technical Field

[0001] This utility model belongs to the technical field of cattle and sheep watering equipment, specifically relating to a continuous watering device. Background Technology

[0002] Traditional yak farming relies heavily on natural water sources or manual, timed water supply, which presents challenges such as high labor intensity, susceptibility to water pollution, freezing temperatures in winter, and unstable water supply, hindering the modernization of livestock farming in high-altitude pastoral areas. Continuous water supply technology has emerged to address this issue. Its core features include integrated pressure-stabilized water supply, automatic water level control, heating and insulation, and water filtration. The system is powered by clean energy sources such as solar or wind power, combined with temperature control equipment to ensure the water doesn't freeze in winter, and automatic water replenishment via float valves or electronic sensors. This technology aims to provide yaks with clean, temperature-controlled drinking water 24 hours a day, significantly improving management efficiency and animal welfare, and is a key technological tool for promoting smart animal husbandry in high-altitude pastoral areas.

[0003] A search revealed a Chinese patent publication number CN 219844540 U, ​​which discloses a layered water feeding device. When the water level in the lower trough decreases, a float descends, causing a sealing plate to descend simultaneously, opening the outlets and allowing water to flow downwards. When the water level in the lower trough increases, the float rises, causing the sealing plate to close the outlet, preventing water from flowing continuously downwards and wasting drinking water. The combined action of the filter plate and activated carbon filter layer ensures that the drinking water flowing into the lower trough remains clean. As the water flows down through the outlets, it enters the water storage tank. When the limiting block accumulates a significant amount of water, it rotates the rotating rod, simultaneously rotating the wheel, which pulls the scraper, pushing the dirt flowing onto the filter plate to the edge of the upper cavity, preventing excessive impurities and dirt from clogging the filter holes on the filter plate.

[0004] The above-mentioned patent has the following shortcomings: In winter, the temperature in some yak breeding sites is low, which often causes water tanks and water pipes to freeze. In addition, these yak breeding sites may have energy shortages and cannot use electric heating equipment in time, making winter feeding of yaks a major problem.

[0005] To address this, a continuous water supply device is proposed, which buries the main water storage section below the permafrost layer and uses geothermal energy for natural insulation, leaving only a water-saving drinking trough on the surface for on-demand water supply, and achieves linkage through simple electrical control. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a solution that can effectively solve the problems of easy freezing of drinking water, energy shortage and inconvenience of management in high-altitude pastoral areas during winter. It takes into account antifreeze, water saving, reliability and automation, and is suitable for yaks, a large livestock that are free-range in high-altitude and cold environments.

[0007] To address one or more of the above-mentioned defects or improvement needs of the existing technology, this utility model provides a continuous water feeding device, including a water feeding trough and a water storage tank. The water storage tank is located underground, and the tank wall has a double-layer hollow structure with an insulation layer filling the middle of the double-layer structure. A water inlet pipe is welded to one end of the water storage tank, extending to the ground. A water supply pipe is welded to the end of the water storage tank away from the water inlet pipe, extending to the ground, and the end of the water supply pipe away from the water storage tank is fixedly connected to the water feeding trough by bolts.

[0008] In some embodiments, a first baffle is bolted to the side of the water trough away from the water supply pipe, and an infrared transmitter is bolted to the surface of the first baffle. A second baffle is bolted to the side of the water trough near the water supply pipe, and an infrared receiver is bolted to the surface of the second baffle.

[0009] In some embodiments, the infrared transmitter and the infrared receiver are installed correspondingly, an electrically controlled door is slidably connected to the outer wall of the water feeding trough, a water pump is fixedly connected to the inner wall of the end of the water feeding trough near the water supply pipe by bolts, and a control device is fixedly installed on the outer wall of the end of the water feeding trough near the water supply pipe by bolts.

[0010] In some embodiments, the control device includes a signal receiving device and a programmable logic controller (PLC), which are electrically connected. The signal receiving device is electrically connected to an infrared receiving device, and the PLC and the water pump are electrically connected to the electrically controlled door.

[0011] In some embodiments, the water pump inlet is fixedly connected to the water supply pipe by bolts, the water pump outlet is fixedly connected to the water outlet pipe by bolts, and the end of the water outlet pipe away from the water pump is fixedly connected to the float valve by bolts.

[0012] In some embodiments, the water trough has a drain outlet at the end away from the water pump, and a drain pipe is fixedly connected to the inner wall of the drain outlet by bolts. The electrically controlled door is slidably connected to the drain pipe.

[0013] In some embodiments, a door lock is fixed to the surface of the control device.

[0014] In some embodiments, a base is fixedly installed at the bottom of the water feeding trough.

[0015] In summary, the technical solutions conceived by this invention have the following beneficial effects compared with the prior art:

[0016] 1. This utility model discloses a continuous water supply device that utilizes geothermal energy for natural insulation by installing a water storage tank below the frost line. The tank walls are typically made of stainless steel or food-grade polyethylene through rotational molding, ensuring durability, non-toxicity, and harmlessness. The insulation layer is made of high-efficiency insulation materials such as polyurethane foam, which significantly slows down heat exchange between the ground and the surface, ensuring the water source does not become too cold in winter. The tank can store water for several days, and the user only needs to supply water to the tank periodically through the inlet pipe. When in use, a water pump is turned on to draw water from the tank, which then flows into the water supply trough through the inlet pipe. Its anti-freezing function does not rely on electricity or fuel, perfectly adapting to the reality of often unstable power supply in pastoral areas, and solving the problem of electric heating solutions being "unusable or unaffordable."

[0017] 2. This utility model discloses a continuous water supply device. An infrared receiver transmits signals to a control device, which contains a signal receiver. A programmable logic controller (PLC) within the control device controls the water pump. When yaks come to drink, the infrared receiver is blocked, triggering a signal to the control device. The control device then activates the water pump, drawing water from the storage tank into the water trough. A float valve controls the water level in the trough to prevent overflow and waste. When the infrared receiver receives a new signal, it delays for 30 seconds to ensure there is no more drinking water for the yaks before the control device shuts off the water pump. This device achieves "on-demand water supply." Water is only provided when yaks drink, significantly reducing the labor intensity of herders. The readily available drinking water also significantly increases yak water intake, promoting digestion and absorption, and improving feed conversion rate.

[0018] 3. This utility model discloses a continuous water feeding device, which transmits signals to a control device equipped with an infrared receiver. The control device then uses a programmable logic controller to control an electrically controlled door. When the infrared receiver is blocked, the control device closes the electrically controlled door, allowing water to accumulate in the water feeding trough. When the infrared receiver receives the signal again, it delays for 30 seconds to ensure there is no drinking water for the yaks. Then, the control device shuts off the water pump and opens the electrically controlled door, draining the remaining water from the water feeding trough through a drain pipe. This prevents surface pollution and algae growth, resulting in cleaner and more hygienic water. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please refer to Figure 1-5 A continuous water supply device includes a water supply trough 1 and a water storage tank 2. The water storage tank 2 is located underground. The tank wall of the water storage tank 2 has a double-layer hollow structure, with an insulation layer 18 filling the middle of the double-layer structure. A water inlet pipe 7 is welded to one end of the water storage tank 2 and extends to the ground. A water supply pipe 3 is welded to the end of the water storage tank 2 away from the water inlet pipe 7 and extends to the ground. The end of the water supply pipe 3 away from the water storage tank 2 is fixedly connected to the water supply trough 1 by bolts.

[0028] The water storage tank 2 is installed underground below the frost line, utilizing geothermal energy for natural insulation. The tank walls are typically made of stainless steel or food-grade polyethylene through rotational molding, ensuring durability, non-toxicity, and harmlessness. The insulation layer 18 of the water storage tank 2 is made of high-efficiency insulation materials such as polyurethane foam, which significantly slows down heat exchange between the underground and surface, ensuring the water source does not become too cold in winter. The water storage tank 2 can store water for several days; users only need to supply water to the tank 2 periodically through the inlet pipe 7. When in use, water is drawn from the water storage tank 2 through the water supply pipe 3 into the water trough 1. Its anti-freezing function does not rely on electricity or fuel, perfectly adapting to the reality of often unstable power supply in pastoral areas, solving the problem of electric heating solutions being "unusable or unaffordable."

[0029] In this embodiment, a first baffle 8 is bolted to the side of the water trough 1 away from the water supply pipe 3, and an infrared transmitter 13 is bolted to the surface of the first baffle 8. A second baffle 17 is bolted to the side of the water trough 1 near the water supply pipe 3, and an infrared receiver 14 is bolted to the surface of the second baffle 17. The infrared transmitter 13 and the infrared receiver 14 are installed correspondingly.

[0030] By installing infrared transmitter 13 and infrared receiver 14, it is possible to automatically detect whether yaks are coming to drink water. When yaks come to drink water, the infrared receiver 14 will not be able to receive the signal, thus sending a signal that yaks have come to drink water. When yaks leave, the infrared receiver 14 will receive the signal again, thus sending a signal that yaks have left. The infrared transmitter 13 and infrared receiver 14 are the prerequisites for the automation of the entire device.

[0031] An electrically controlled door 16 is slidably connected to the outer wall of the water feeding trough 1. A water pump 4 is bolted to the inner wall of the end of the water feeding trough 1 closest to the water supply pipe 3. A control device 5 is bolted to the outer wall of the end of the water feeding trough 1 closest to the water supply pipe 3. The control device 5 contains a signal receiving device and a programmable logic controller (PLC). The signal receiving device and the PLC are electrically connected. The signal receiving device in the control device 5 is electrically connected to an infrared receiving device 14. The PLC and the water pump 4 in the control device 5 are electrically connected to the electrically controlled door 16.

[0032] The infrared receiver 14 transmits a signal to a signal receiver within the control device 5. The programmable logic controller (PLC) within the control device 5 then controls the electric gate 16 and the water pump 4. When yaks come to drink, the infrared receiver 14 is blocked and sends a signal to the control device 5. The control device 5 then activates the water pump 4, closing the electric gate 16 and drawing water from the water storage tank 2 into the water trough 1. When the infrared receiver 14 receives the signal again, it sends another signal to the control device 5. After a 30-second delay to ensure there is no more drinking water for the yaks, the control device 5 then activates the water pump 4, closing the electric gate 16 and opening it. This device achieves "on-demand water supply," replenishing water only when yaks drink. Simultaneously, the electric gate 16 opens when the water pump 4 closes, draining any remaining water from the water trough 1 through the electric gate 16. This prevents surface pollution and algae growth, resulting in cleaner and more hygienic water, which is beneficial to the health of the yaks.

[0033] In this embodiment, the inlet of the water pump 4 is fixedly connected to the water supply pipe 3 by bolts, and the outlet of the water pump 4 is fixedly connected to the outlet pipe 12 by bolts. A float valve 11 is fixedly connected to the end of the outlet pipe 12 away from the water pump 4 by bolts. A drain outlet 9 is provided at the end of the water feeding trough 1 away from the water pump 4, and a drain pipe 10 is fixedly connected to the inner wall of the drain outlet 9 by bolts. The electrically controlled door 16 is slidably connected to the drain pipe 10. A door lock 6 is fixedly mounted on the surface of the control device 5. A base 15 is fixedly installed at the bottom of the water feeding trough 1.

[0034] The float valve 11 controls the water level in the water trough 1, ensuring that water does not overflow and cause waste. Simultaneously, when the electrically controlled door 16 is opened, any remaining water in the water trough 1 is drained and directed to the grassland for reuse via the drain pipe 10, avoiding waste. The door lock 6 installed in the control device 5 prevents unauthorized access to the control system, thus preventing property damage. The water trough 1 is made of thickened stainless steel and embedded in a concrete base 15 to prevent it from being kicked over or damaged by yaks.

[0035] In this example, a continuous water feeding device is connected to a water pump 4 via an electric control door 16, a control device 5, and an infrared device. When the infrared receiver 14 is blocked, the control device 5 will close the electric control door 16, start the water pump 4, and continuously draw water from the underground water storage tank 2 into the water feeding trough 1 until the float valve 11 is activated to block the outlet pipe 12. When the infrared receiver 14 receives the water again, it will delay for 30 seconds to ensure that there is no drinking water source for yaks. Then, the control device 5 will open the electric control door 16, turn off the water pump 4, and discharge the used water into the water feeding trough 1 through the drain pipe 10, thus achieving a cycle. This way, no water will remain in the pipe, so the pipe will not freeze, which would make it difficult to discharge water. It also allows dirty water to be discharged in time after drinking, preventing the water source from freezing in the trough.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
