The flip cover is rotatably connected to the water tank through the mounting ear plate.

[0019] The beneficial effects of this utility model are:

[0020] 1. When using this utility model, starting the circulating water pump activates the circulating water pipe located at the bottom of the water tank, drawing water from the bottom of the tank. The drawn-in water is pumped to the circulating water pump via the circulating water pipe, and then enters the filter box through the outlet pipe. In the filter box, the water is filtered through the filter screen to remove impurities, suspended solids, and pollutants such as cattle and sheep manure. The filtered water then flows out from the drain pipe connected to the bottom of the filter box, passes through the telescopic hose, and finally flows back into the water tank through the drain float. Because the drain float floats with changes in water level, it can always maintain the drain outlet at a suitable water level, thus continuously completing the water circulation. During the circulation process, impurities, suspended solids, and manure are continuously filtered out, preventing sedimentation and accumulation. At the same time, it can inhibit the growth and reproduction of microorganisms, reduce harmful bacteria and pathogens, ensure the health of cattle and sheep drinking water, and reduce the risk of disease.

[0021] 2. This utility model, by setting up an upper filter screen and a lower filter screen, allows the upper filter screen with larger pores to intercept larger particles of impurities, such as wool, sheep hair, and feed residue. The lower filter screen with smaller pores can further filter finer impurities, such as silt and microorganisms. This tiered filtration method can significantly improve the filtration effect and make the water purer. At the same time, the filter box is connected to the upper and lower filter screens by a sliding rail and is fixed by a sealing plate. When it is necessary to clean or replace the filter screens, simply unscrew the screws on the sealing plate to easily remove the upper and lower filter screens. The operation is simple and convenient, which helps to maintain the good performance of the filtration system.

[0022] 3. By setting up an insulation layer, this utility model can effectively reduce the rate of water temperature loss inside the water tank and reduce heat loss.

[0023] 4. By setting a heating element, this utility model can maintain the water temperature within a suitable range, allowing cattle and sheep to drink water that is neither too hot nor too cold. This reduces the stimulation to the stomach and intestines of cattle and sheep caused by excessively low water temperature, which is beneficial to their health and digestion and absorption. It can also improve the cold resistance and production performance of cattle and sheep in cold environments, and prevent cold water from consuming their body heat, thus affecting their weight gain and overall health.

[0024] 5. This utility model, by setting up a first water inlet pipe, a second water inlet pipe, a three-way solenoid valve A, a water distribution backwash pipe, a drain pipe, a telescopic hose, and a three-way solenoid valve B, can first efficiently filter water during water circulation. During water circulation, the three-way solenoid valve A is closed and the three-way solenoid valve B is opened, so that the drain pipe and the telescopic hose are connected. The water at the bottom of the drinking tank enters the filter box through the circulating water pump through the circulating water pipe. The upper filter screen first intercepts large particles such as hair and feed residue, and the lower filter screen then filters small particles such as mud and microorganisms. The filtered water flows from the drain pipe through the telescopic hose into the drain float plate, and then back into the drinking tank, continuously purifying the water quality and ensuring the health of cattle and sheep drinking water.

[0025] Secondly, it can perform water addition operations. When water needs to be added, close the three-way solenoid valve B and open the three-way solenoid valve A to connect the first and second water inlet pipes. Close the backwash pipe and the external water supply equipment will sequentially send external water through the second water inlet pipe, the three-way solenoid valve A, and the first water inlet pipe into the filter box for filtration. Then, the water will flow into the drinking tank through the drain pipe and the telescopic hose from the drain float to maintain the water level in the tank and meet the daily drinking water needs of cattle and sheep.

[0026] Furthermore, it can perform automatic backwashing maintenance. When the filter holes of the upper and lower filters are clogged, the three-way solenoid valves A and B are opened simultaneously, connecting the second inlet pipe, the backwash pipe, and the drain pipe. External water flows through the second inlet pipe, the three-way solenoid valve A, the backwash pipe, and the three-way solenoid valve B, and then backwashes into the filter box through the drain pipe to rinse the upper and lower filters. The reverse water pressure can force the impurities accumulated in the filter holes out, thereby reducing the probability of filter clogging and extending the service life of the filter.

[0027] 6. By setting up a drainage float, this utility model makes it less likely for cattle and sheep to be disturbed when drinking water, allowing them to drink more peacefully. This helps them maintain good drinking habits and eating habits, avoids choking or injury caused by fright, and ensures their drinking safety and health. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] like Figures 1 to 9 As shown, a cattle and sheep heat-insulating circulating drinking water device includes a drinking tank 1, which is equipped with a circulating filter component and a heating and heat-insulating component. The circulating filter component achieves water circulation filtration, and the heating and heat-insulating component keeps the water warm to ensure the health of the livestock drinking water.

[0041] The circulating filtration assembly includes a filter box 5, an outlet pipe 23, and a drain pipe 11. The filter box 5 is suspended in the inner cavity of the water tank 1. The outlet pipe 23 is connected to the upper end of the filter box 5, and the drain pipe 11 is connected to the lower end of the filter box 5. A buffer drain unit is provided at the bottom end of the drain pipe 11. A filter unit is provided inside the filter box 5.

[0042] The heating and heat preservation component includes a heating tube 18, which is embedded in the inner bottom surface of the water tank 1;

[0043] The water tank 1 is also equipped with a water filling component and a backwashing component. The water filling component is connected to one side of the filter box 5, and the backwashing component is located at the bottom of the filter box 5. The backwashing component is connected to the water filling component.

[0044] The water filling assembly includes a first water inlet pipe 8, and the backwashing assembly includes a water distribution backwash pipe 10. The first water inlet pipe 8 is connected to the upper end of the filter box 5, one end of the water distribution backwash pipe 10 is connected to the first water inlet pipe 8, and the other end of the water distribution backwash pipe 10 is connected to the bottom end of the filter box 5. It should be noted that one-way valves are installed at the end of the water outlet pipe 23 connected to the filter box 5 and the end of the first water inlet pipe 8 connected to the filter box 5, so as to prevent some water from flowing back into the water outlet pipe 23 or the first water inlet pipe 8 during backwashing.

[0045] Example 2

[0046] Improvements based on Example 1:

[0047] Furthermore, hollow support rods 4 are fixedly connected to both sides of the filter box 5. A circulating water pipe 6 is fixedly connected inside one of the hollow support rods 4. The bottom end of the circulating water pipe 6 passes through the hollow support rod 4 and extends to the bottom of the water tank 1. A filter screen 7 is fixedly fitted to the bottom end of the circulating water pipe 6. The outlet end of the circulating water pipe 6 is connected to the outlet pipe 23, and a circulating water pump 22 is connected between the circulating water pipe 6 and the outlet pipe 23. The circulating water pump 22 is fixedly installed on the surface of the filter box 5, providing stable support for the filter box 5 through the hollow support rods 4. The circulating water pipe 6 is installed in a concealed manner, which provides some protection for the circulating water pipe 6. Furthermore, during use… When the circulating water pump 22 is started, the circulating water pipe 6 located at the bottom of the drinking tank 1 begins to work, drawing water from the bottom of the tank. The drawn water is pumped to the circulating water pump 22 through the circulating water pipe 6, and then enters the filter box 5 through the outlet pipe 23. In the filter box 5, impurities, suspended solids, and pollutants such as cattle and sheep manure are removed. The filtered water then flows out from the drain pipe 11 connected to the bottom of the filter box 5, passes through the telescopic hose 13, and is finally discharged back into the drinking tank 1 through the drain float 14. This achieves water circulation filtration, which can continuously filter out impurities, suspended solids, and manure, prevent sedimentation and accumulation, and inhibit the growth and reproduction of microorganisms, reduce harmful bacteria and pathogens, ensure the health of cattle and sheep drinking water, and reduce the risk of disease.

[0048] Furthermore, the buffer drainage unit includes a telescopic hose 13 and a drainage float 14. The bottom end of the drain pipe 11 is provided with a telescopic hose 13, and the bottom end of the telescopic hose 13 is fixedly connected to the drainage float 14 to ensure that the drainage float 14 can always be located on the water surface. Therefore, when circulating water is transported back into the tank, it will not make a loud noise or cause water splashes, thereby avoiding frightening or disturbing the drinking livestock.

[0049] Furthermore, the filtration unit includes an upper filter screen 16 and a lower filter screen 17, which are slidably connected inside the filter box 5 via slide rails. The pore size of the upper filter screen 16 is larger than that of the lower filter screen 17. A sealing plate 15 is fixedly connected to the surface of the filter box 5 by screws. In use, the larger pore size of the upper filter screen 16 can first intercept larger particulate impurities, such as wool hair and feed residue; the smaller pore size of the lower filter screen 17 can further filter fine impurities, such as silt and microorganisms. Through this graded filtration method, the filtration effect can be significantly improved, making the water purer.

[0050] Furthermore, an insulation layer 3 is fixedly installed on the outer surface of the water tank 1. The insulation layer 3 is filled with polyurethane foam material. The heating tube 18 is bent on the inner bottom surface of the water tank 1. The insulation layer 3 can effectively reduce the rate of water temperature loss inside the water tank 1 and reduce heat loss. The heating tube 18 can maintain the water temperature within a suitable range, allowing cattle and sheep to drink water that is neither too hot nor too cold. This reduces the stimulation to the stomach and intestines of cattle and sheep caused by excessively low water temperature, which is conducive to the health and digestion and absorption of cattle and sheep. It can improve the cold resistance and production performance of cattle and sheep in cold environments and prevent cold water from consuming their body heat, thus affecting their weight gain and overall health.

[0051] Furthermore, the first water inlet pipe 8 is fixedly connected inside another hollow support rod 4. The bottom end of the first water inlet pipe 8 is connected to the second water inlet pipe 24. The second water inlet pipe 24 passes through the hollow support rod 4 and the water tank 1 in sequence, and extends to the outside of the water tank 1, realizing a hidden connection of the water inlet pipe. This also provides a certain degree of protection for the water inlet pipe. When water is added to the tank through the water inlet pipe, the added water is also transported to the tank through the drain float 14, which can also ensure that no loud noise or splashing occurs when adding water, thereby avoiding startling or disturbing the drinking livestock.

[0052] Furthermore, a three-way solenoid valve A9 is fixedly connected between the water distribution backflushing pipe 10 and the first water inlet pipe 8, and a three-way solenoid valve B12 is fixedly connected between the water distribution backflushing pipe 10 and the drain pipe 11. The drain pipe 11 is fixedly connected to the telescopic hose 13 through the three-way solenoid valve B12. The on / off state of the three-way solenoid valve A9 and the three-way solenoid valve B12 can be controlled according to the actual water demand, thereby achieving different usage requirements.

[0053] Furthermore, the bottom surface of the water tank 1 is fixedly connected to rollers 19 with built-in brakes near its four corners, which makes it convenient to adjust the position of the water tank 1 according to actual needs and is easy to use.

[0054] Furthermore, a water level sensor 20 is fixedly connected to the inner wall of the water tank 1, and a controller 25 is fixedly connected to one side surface of the water tank 1. The three-way solenoid valve A9, the three-way solenoid valve B12, and the water level sensor 20 are all electrically connected to the controller 25. The water filling process is automated through the controller 25, eliminating the need for frequent manual inspection and operation, saving labor costs, and improving ease of use.

[0055] Furthermore, a flip cover 2 is provided at the upper opening of the water tank 1, and an mounting ear plate 21 is connected to the middle part of one of the long sides of the water tank 1. The side of the flip cover 2 is rotatably connected to the water tank 1 through the mounting ear plate 21, which can seal the water tank 1 when not in use and prevent dust from accumulating inside the water tank 1 during storage.

[0056] Working principle: When using this drinking device, first move the water tank 1 to a suitable position using the roller 19, then apply the brake, then open the flip cover 2 and connect the second water inlet pipe 24 to the external water supply equipment. When using the device for the first time, manually inject an appropriate amount of water into the water tank 1, and then the cattle and sheep can drink. During this process, as cattle and sheep drink, the water level sensor 20 transmits the water level change signal to the controller 25. The controller 25 determines that the water level is too low and starts the external water supply facility. When the water level rises to a suitable height, the water level sensor 20 transmits the water level change signal to the controller 25, and the controller 25 controls the external water supply facility to stop supplying water. In addition, the controller 25 closes the three-way solenoid valve B12 and opens the three-way solenoid valve A9, connecting the first water inlet pipe 8 and the second water inlet pipe 24. The backwash pipe 10 is closed. The external water source flows through the second water inlet pipe 24, through the three-way solenoid valve A9 and the first water inlet pipe 8, and enters the filter box 5. In the filter box 5, the water first passes through the upper filter screen 16 to intercept larger particles of impurities, and then through the lower filter screen 17 to filter fine impurities such as silt and microorganisms. The filtered water flows out from the drain pipe 11 connected to the bottom of the filter box 5, passes through the telescopic hose 13, and flows into the drinking tank 1 from the drain float 14. Since the drain float 14 will float with the water level, it can always keep the drain outlet at a suitable water level, thereby continuously completing the water circulation, constantly filtering out impurities, suspended solids and feces, inhibiting the growth and reproduction of microorganisms, and ensuring the health of cattle and sheep drinking water.

[0057] During this process, when the filter holes of the upper filter screen 16 and the lower filter screen 17 become clogged, the three-way solenoid valves A9 and B12 are simultaneously opened, connecting the second inlet pipe 24, the backwash pipe 10, and the drain pipe 11. External water flows through the second inlet pipe 24, the three-way solenoid valve A9, the backwash pipe 10, and the three-way solenoid valve B12, and is flushed back into the filter box 5 from the drain pipe 11. The water pressure generated by the reverse water flow forces the impurities accumulated in the filter holes out of the filter holes. The impurities are discharged through the circulating water pipe 6, completing the flushing of the upper filter screen 16 and the lower filter screen 17, reducing the probability of filter screen clogging and extending the service life of the filter screen.

[0058] When cattle and sheep drink water in winter, the heating pipe 18 can be turned on to heat the water in the water tank 1 and maintain the water temperature at a suitable drinking temperature for cattle and sheep. At the same time, the circulating water pump 22 can be started. The circulating water pipe 6 draws water from the bottom of the water tank 1. The water is transported to the circulating water pipe 6 through the circulating water pump 22, and then flows out from the drain pipe 11 connected to the bottom of the filter box 5. Finally, it flows back to the water tank 1, so that the water forms a circulation in the tank. This can effectively prevent obvious water temperature stratification, keep the water temperature uniform, and through the heat insulation layer 3, effectively reduce the rate of water temperature loss inside the water tank 1, reduce heat loss, and save energy.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
