Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, specifically to a self-purifying water drinking device for cattle. Background Technology

[0002] In modern cattle farming, the health and growth of cattle are directly linked to farming efficiency. Water is a crucial medium for cattle metabolism, nutrient transport, and thermoregulation, making the quality of water supply equipment paramount. Watering equipment must not only meet the cattle's daily demand for large quantities of water, but its hygiene is also critical. Unclean drinking water easily breeds bacteria such as E. coli and Salmonella, causing diseases like diarrhea and septicemia in cattle, reducing their resistance and productivity, and increasing farming costs and the difficulty of disease control.

[0003] Utility model patent application number CN202322050596.3 discloses a drinking water device for cattle and sheep. This device includes a water trough with a threaded cap at the bottom. The water trough is rotatably mounted on two legs of a support frame. Limiting blocks movably pass through the legs of the support frame. Limiting grooves are fixedly installed on both sides of the water trough, and the limiting blocks are movably inserted into the limiting grooves. During use, the filter assembly in the water trough allows cattle and sheep to drink water directly from the filter assembly. Lifting the filter assembly in the water trough facilitates the removal of grass and some impurities from the water. A scraper facilitates the removal of accumulated dirt from the filter assembly and the inner wall of the water trough, making it easier to clean the water and maintain its cleanliness. The support frame also allows for easy rotation of the water trough to empty wastewater.

[0004] Although the existing drinking water device for cattle and sheep can remove impurities from the water through filtration, it still has the following problems in actual use: The device filters drinking water through a simple filter screen, which can only remove some larger particles and cannot disinfect the water source. When cattle drink, saliva, oral microorganisms, or feed enter the water. These contaminants not only form suspended solids in the water but also provide abundant nutrients for bacteria, algae, and other microorganisms, accelerating water deterioration. Over time, the number of microorganisms in the remaining water in the trough increases dramatically, the organic matter content rises significantly, and the water quality deteriorates rapidly. This situation, coupled with the continued rapid increase in microorganisms and organic matter in the remaining water, seriously endangers the drinking water safety and health of the cattle. Therefore, we propose a self-purifying drinking water device for cattle. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose a self-purifying cattle drinking water device that, through the synergistic effect of multiple purification structures, reduces the number of microorganisms and the content of organic matter in the water, prevents water quality deterioration, ensures the safety of drinking water and the health of cattle, and effectively meets the hygiene requirements for cattle drinking water.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-purifying water supply system for cattle, comprising:

[0008] A drinking trough is used to hold water and has an open top. A drain hole is provided at the bottom of the drinking trough, and a drain pipe is installed at the bottom of the drain hole. A water pump is provided at the back of the drain pipe, and the drain pipe is connected to the water inlet of the water pump. A bend is installed at the drain outlet of the water pump.

[0009] The purification unit, used to purify the residual water in the drinking trough, is installed at the rear top of the drinking trough; it includes a first filter box, a second filter box, and a disinfection box arranged sequentially from top to bottom.

[0010] The end of the bend is connected to the inner cavity of the first filter box; a partition is fixed inside the first filter box, and a cylinder for coarse filtration of water source is rotatably installed at the fixing holes at both ends of the partition. Multiple filter holes are opened on the outer wall of the cylinder; a drive shaft is coaxially fixed at the bottom inside the top opening of the cylinder, and a drive groove is opened at the top of the drive shaft; a transmission component for driving the drive shaft to rotate is installed above the partition.

[0011] The second filter box has a support mesh with a hollow structure fixed inside near the bottom. Multiple fine filter layers are arranged on the top of the support mesh from bottom to top.

[0012] The disinfection box is fixed to the bottom of the second filter box. Multiple semi-submersible disinfection lamps are fixed to the outer walls on both sides of the disinfection box and penetrate into the interior of the disinfection box. A return water pipe for discharging purified water is provided at the bottom front of the disinfection box, and the front end of the return water pipe extends to the top of the drinking trough.

[0013] In addition, the self-purifying cattle drinking device proposed in the application may also have the following additional technical features:

[0014] Specifically, the front end of the water trough is open, and the water trough is made of food-grade stainless steel.

[0015] This design makes it convenient and safe for cattle to drink water.

[0016] Specifically, side plates are fixedly connected to both sides of the drinking trough by bolts, and the side plates are fixedly connected to the first filter box, the second filter box and the disinfection box by bolts respectively;

[0017] In this setup, the support plate provides stable support for the purification section.

[0018] Specifically, a first cover plate is installed on the top of the first filter box, and the first cover plate is fixed to the first filter box by bolts;

[0019] In this configuration, the bolt-fixed first cover plate has the advantage of being easy to install and remove.

[0020] Specifically, the transmission assembly includes a transmission block that is inserted into the transmission slot, a connecting shaft that is coaxially keyed to the top of the transmission block, the connecting shaft passing through the first cover plate and rotatably connected to the first cover plate, and pulleys that are coaxially keyed to the top of the connecting shaft, with a belt sleeved between the two pulleys; a motor for driving the connecting shaft on one side to rotate is installed above the first cover plate;

[0021] This setting improves the filtration efficiency of the water source by rotating the filter cartridge.

[0022] Specifically, the transmission block and the connecting shaft are integrally formed, and the cross-sectional shape of both the transmission block and the transmission groove is triangular.

[0023] In this design, the one-piece molding ensures the connection stability between the transmission block and the connecting shaft, thus guaranteeing the stability of the transmission.

[0024] Specifically, a second cover plate is fixedly installed on the top of the second filter box by bolts, and the second cover plate is fixedly connected to the bottom of the first filter box by bolts. A connecting groove communicating with the first filter box is opened on the top of the second cover plate.

[0025] This design facilitates a stable connection between the first and second filter boxes and promotes water flow.

[0026] Specifically, the support mesh is woven from 304 stainless steel wire, and the mesh openings are regular hexagonal with an inscribed circle diameter of 3-5 mm.

[0027] This design not only supports multiple fine filter layers but also offers excellent water flow performance.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] The residual water from the drinking troughs, contaminated with cattle saliva and feed, is pumped to the purification unit. In the first filter box, a rotating cylinder performs coarse filtration, intercepting large particles. Compared to simple filter screens, this method is more efficient and reduces clogging. The second filter box contains multiple fine filtration layers with a support mesh to further remove fine impurities and some microorganisms. A semi-submersible disinfection lamp in the disinfection box sterilizes the water flow, effectively solving the problem of existing devices being unable to disinfect the water source. This design, through the synergistic effect of multiple purification structures, reduces the number of microorganisms and organic matter in the water, prevents water quality deterioration, ensures the safety of drinking water and the health of the cattle, and effectively meets the hygiene requirements for cattle drinking water.

[0040] 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.

[0041] Example 1

[0042] Please see Figures 1-2 As shown, a self-purifying cattle drinking device includes a drinking trough 1 for holding water and is open at the top; a drain hole is provided at the bottom of the drinking trough 1, a drain pipe 11 is installed at the bottom of the drain hole, a water pump 12 is provided at the rear of the drain pipe 11, and the drain pipe 11 is connected to the water inlet of the water pump 12, and a bend 13 is installed at the drain outlet of the water pump 12.

[0043] With the above-mentioned design, the drinking trough 1 with the top opening facilitates drinking for cattle; the combination of the bottom drain hole, drain pipe 11, water pump 12 and bend pipe 13 can promptly extract the residual water in the drinking trough and transport it to the purification department for treatment, thus preventing sewage from stagnating for a long time and breeding bacteria.

[0044] Please see Figures 1-2 As shown, in this embodiment, side plates 2 are fixedly connected to both sides of the drinking water tank 1 by bolts. The side plates 2 are fixedly connected to the first filter box 30, the second filter box 31, and the disinfection box 32 by bolts respectively. This connection method makes the entire device structure stable, facilitates installation and disassembly, and makes it convenient for later maintenance and repair.

[0045] Please see Figures 2-4 As shown, the purification unit 3, used to purify the residual water in the drinking water tank 1, is installed at the rear upper part of the drinking water tank 1; it includes a first filter box 30, a second filter box 31, and a disinfection box 32 arranged sequentially from top to bottom; the end of the bent pipe 13 is connected to the inner cavity of the first filter box 30; a partition plate 302 is fixed inside the first filter box 30, and a cylinder 33 for coarse filtration of the water source is rotatably installed at the fixing holes at both ends of the partition plate 302; multiple filter holes are opened on the outer wall of the cylinder 33; a drive shaft 34 is coaxially fixed at the bottom inside the top opening of the cylinder 33. The top of the 4 is provided with a transmission groove 340; the interior of the second filter box 31 is fixed with a hollow structure support net 310 near the bottom, and multiple fine filter layers 311 are arranged from bottom to top on the support net 310; the disinfection box 32 is fixed to the bottom of the second filter box 31, and multiple semi-submersible disinfection lamps 320 are fixed on the outer walls of both sides of the disinfection box 32 and penetrate into the interior of the disinfection box 32; a return water pipe 321 for discharging purified water is provided at the bottom front of the disinfection box 32, and the front end of the return water pipe 321 extends to the top of the drinking water tank 1.

[0046] Through the above configuration, the purification unit 3, consisting of the first filter box 30, the second filter box 31, and the disinfection box 32, achieves multi-stage purification of the water source. The rotating cylinder 33 inside the first filter box 30 performs coarse filtration, which can intercept large particulate impurities; the support mesh 310 and multiple fine filter layers 311 inside the second filter box 31 further remove fine impurities; the semi-submersible disinfection lamps 320 inside the disinfection box 32 sterilize and disinfect the water flow, effectively ensuring water quality safety.

[0047] In this embodiment, the outer wall of the cylinder 33 is coaxially and tightly welded with rings 330 at both the upper and lower ends of the partition 302. The two rings 330 are respectively attached to the upper and lower end faces of the partition 302. When the cylinder 33 rotates, the rings 330 can assist the rotation of the cylinder 33 to a certain extent, making the rotation of the cylinder 33 more stable and smooth, reducing the jamming caused by installation gaps or uneven force, and improving the smoothness and reliability of the overall equipment operation.

[0048] Please see Figure 4 As shown, further, a transmission assembly for driving the drive shaft 34 to rotate is installed above the partition 302; the transmission assembly includes a transmission block 35 that is inserted into the transmission groove 340, a connecting shaft 36 is coaxially keyed to the top of the transmission block 35, the connecting shaft 36 passes through the first cover plate 300 and is rotatably connected to the first cover plate 300, and pulleys 37 are coaxially keyed to the top of each connecting shaft 36, with a belt 38 sleeved between the two pulleys 37; a motor 39 for driving the connecting shaft 36 on one side to rotate is installed above the first cover plate 300. This design drives the other connecting shaft 36 to rotate through the belt 38, thereby causing the transmission block 35 to drive the drive shaft 34 to rotate the cylinder 33, which can realize dynamic coarse filtration of the water source and improve filtration efficiency.

[0049] In this embodiment, the front end of the water trough 1 is open, and the water trough 1 is made of food-grade stainless steel. Food-grade stainless steel is safe, non-toxic, corrosion-resistant, and does not easily rust, ensuring the hygiene of the drinking water; the open front design conforms to the drinking habits of cattle and makes it convenient for the cattle to drink.

[0050] In this embodiment, a first cover plate 300 is installed on the top of the first filter box 30, and the first cover plate 300 is fixed to the first filter box 30 by bolts. The first cover plate 300 can effectively prevent debris from entering the interior of the first filter box 30, and at the same time facilitates opening the cover plate to clean and maintain the internal components such as the cylinder 33.

[0051] In this embodiment, the transmission block 35 and the connecting shaft 36 are integrally formed structures, and the cross-sectional shape of both the transmission block 35 and the transmission groove 340 is triangular. This design structure ensures the stability and reliability of the transmission, effectively transmits torque, and prevents slippage during transmission.

[0052] In this embodiment, a second cover plate 312 is bolted to the top of the second filter box 31. The second cover plate 312 is bolted to the bottom of the first filter box 30. A connecting groove communicating with the first filter box 30 is provided on the top of the second cover plate 312. This design ensures the airtightness of the second filter box 31 and facilitates connection with the first filter box 30, allowing purified water to flow smoothly into the second filter box 31.

[0053] In this embodiment, the support mesh 310 is woven from 304 stainless steel wire. The mesh openings of the support mesh 310 are regular hexagonal, and the inscribed circle diameter of the mesh openings is 3-5 mm. 304 stainless steel is corrosion-resistant and has a long service life; the inscribed circle diameter of the mesh openings is 4 mm, and the regular hexagonal mesh structure is stable, with good water permeability, providing uniform and stable support for the upper fine filter layer 311.

[0054] In this embodiment, a U-shaped bracket 301 is fixedly connected to the top of the first cover plate 300 by bolts, and the motor 39 is fixedly connected to the top of the bracket 301 by bolts. This installation method makes the installation position of the motor 39 stable, and the U-shaped bracket 301 provides reliable support for the motor 39, preventing the motor 39 from shaking during operation, ensuring the stable operation of the transmission components, and thus ensuring the continuous rotation and filtration of the inner cylinder 33 of the first filter box 30.

[0055] In this embodiment, a sealing ring is provided where the semi-submersible disinfection lamp tube 320 passes through the disinfection box 32. The sealing ring can effectively prevent water in the disinfection box 32 from leaking out from the lamp tube perforation, ensuring the airtightness of the disinfection box 32, avoiding the normal operation and service life of the semi-submersible disinfection lamp tube 320 due to water leakage, and preventing water overflow from causing water waste or impacting the surrounding environment.

[0056] It is understood that the preferred number of fine filter layers 311 in this embodiment is three layers. The top layer is a polypropylene melt-blown filter element, made of polypropylene fibers through a high-temperature melt-spinning process, possessing a fine and uniform pore size of 5-10 micrometers. Its unique three-dimensional tortuous pore structure gives it a large specific surface area, effectively intercepting suspended solids, colloids, and some microorganisms in the water, with excellent dirt-holding capacity. The middle layer is an activated carbon fiber felt, made from high-quality activated carbon fibers. With its well-developed microporous structure and ultra-large specific surface area, it can quickly adsorb residual chlorine, odors, pigments, and organic pollutants in the water. It also has a good removal effect on some heavy metal ions and microbial metabolites. Compared with traditional granular activated carbon, it has a faster adsorption rate and higher mechanical strength, effectively improving the purity and safety of water quality. The bottom layer is a ceramic filter element, made of inorganic materials such as natural diatomaceous earth and fired at high temperatures. Its surface is covered with micropores of 0.1-1 micrometers, which can further intercept extremely fine impurities such as bacteria, spores, and colloids, with extremely high filtration precision. Its material is hard, wear-resistant, and has excellent corrosion resistance. It has a long service life and its surface micropores make it easy to clean. When the filtration capacity decreases, simple cleaning can restore some of its performance, providing a fine filtration guarantee for the water source entering the disinfection tank.

[0057] It should be added that a valve 322 is installed on the outside of the return water pipe 321 in this embodiment. The valve 322 is designed to be easy to open and close, thereby facilitating the discharge of purified water.

[0058] It is worth noting that the motor 39 involved in this embodiment is a conventional technology and will not be described in detail here.

[0059] When it is necessary to purify the remaining water in the drinking water tank 1, the user starts the water pump 12. The water pump 12 starts working and pumps the residual water flowing out of the drain hole at the bottom of the drinking water tank 1 through the drain pipe 11 and through the bend pipe 13 into the first filter box 30 of the purification section 3. Then, the user starts the motor 39. The motor 39 starts working, and its output shaft drives the connecting shaft 36 on one side to rotate. The pulley 37 at the top of the connecting shaft 36 rotates accordingly. The belt 38 sleeved between the two pulleys 37 generates transmission, driving the pulley 37 on the other side and the connecting shaft 36 to rotate synchronously. The transmission block 35, which is coaxially keyed to the connecting shaft 36, rotates under the drive of the connecting shaft 36. Since the transmission block 35 and the top of the transmission shaft 34 are connected, the transmission block 35 rotates. The transmission groove 340 of the part is triangular in shape and plugged in. The rotating transmission block 35 transmits torque to the transmission shaft 34, which in turn drives the transmission shaft 34 to rotate the cylinder 33. When the water source enters the cylinder 33, it is thrown to the surroundings and filtered by the filter holes. Next, the water after preliminary filtration flows into the second filter box 31. With the support of the support net 310, it passes through multiple fine filter layers 311 to further remove fine impurities. After that, the water after double filtration enters the disinfection box 32, and the semi-submersible disinfection lamp tube 320 starts to work and sterilizes the water flow. Finally, the purified water is transported back to the top of the drinking water tank 1 through the return water pipe 321 at the bottom of the disinfection box 32, completing the entire purification cycle.

[0060] Example 2

[0061] Please see Figure 5 As shown, this embodiment provides the following technical solution based on embodiment 1: A scraper assembly 4 for cleaning the inner wall of the cylinder 33 is installed at the top center of the partition 302. The scraper assembly 4 includes a support column 40 that is fixedly connected to the top of the partition 302 by bolts. Two support plates 41 are tightly welded to the outer wall of the support column 40. Fixing grooves 410 are opened at both ends of the support plates 41. Limiting bolts 43 are threaded to both ends of the support plates 41. Scrapers 42 are inserted through the fixing grooves 410. The scrapers 42 are inserted into the opening of the cylinder 33 and abut against the inner wall of the cylinder 33. Fixing holes are opened on the outer wall of the scrapers 42, and the ends of the limiting bolts 43 are inserted into the fixing holes.

[0062] With the above configuration, through the combination of support column 40, support plate 41, scraper 42 and limit bolt 43, when the cylinder 33 rotates, the scraper 42 can clean the impurities attached to the inner wall of the cylinder 33, prevent the accumulation of impurities from affecting the filtration effect, and ensure the continuous and efficient operation of the coarse filter.

[0063] In this embodiment, the scraper 42 has a T-shaped cross-section. The T-shaped design prevents the scraper 42 from falling out of the fixing groove 410 during installation, thus improving the ease of installation.

[0064] When the cylinder 33 rotates, since the scraper 42 is in a fixed position, the inner wall of the relatively rotating cylinder 33 comes into contact with the scraper 42. Using the friction between the two, the scraper 42 scrapes off the impurities attached to the inner wall of the cylinder 33, preventing impurities from accumulating and clogging the filter holes, and maintaining the filtration efficiency of the cylinder 33.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
