Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment technology, and in particular to a constant temperature drinking water system with automatic cleaning function. Background Technology

[0002] A constant-temperature drinking water system can precisely control the drinking water temperature (adapting to the different growth stages of livestock and poultry such as pigs, cattle, and sheep), avoiding the stimulation of the gastrointestinal tract by low temperatures or the reduction in water intake due to high temperatures. It can reduce diarrhea and stress reactions in livestock and poultry, improve feed conversion rate and survival rate, and especially ensure sufficient drinking water for livestock and poultry under extreme winter and summer temperatures, helping to accelerate fattening and increase production capacity. However, the weak internal turbulence capacity of existing constant-temperature drinking water systems can lead to poor water circulation in the water tank, creating cleaning dead zones and water temperature stratification, reducing the uniformity of cleaning solution coverage and the accuracy of constant temperature, leaving residual dirt and bacteria, and affecting drinking water safety and user experience.

[0003] A search of Chinese patent documents (authorization announcement number CN217242046U) reveals that this utility model provides a fully automatic circulating constant-temperature drinking water system, relating to the field of livestock breeding technology. It solves the technical problem that existing traditional drinking water systems in cattle farms lack the function of maintaining a constant water temperature. The device includes a heating water tank, a mixing tank, a heater, a water supply component, and a control component. The heater is installed on the heating water tank, and the control component is connected to the heater, controlling the heater to heat the water in the heating water tank and controlling the heating temperature of the heater. The heating water tank and the mixing tank are connected by a connecting pipe. This device can meet basic usage requirements; however, its weak internal turbulence capacity leads to poor water circulation within the tank, creating cleaning dead zones and water temperature stratification, reducing the uniformity of cleaning solution coverage and temperature control accuracy, leaving residual dirt and bacteria, and affecting drinking water safety and user experience. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature drinking water system with automatic cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a constant temperature drinking water system with automatic cleaning function, comprising a constant temperature tank for storing constant temperature water, wherein a hollow guide column for limiting movement displacement is fixedly installed on the top of the constant temperature tank, and a drive motor for driving is installed on the side of the hollow guide column. The output shaft of the drive motor is connected to a threaded rod via a coupling. The threaded rod is rotatably disposed inside the hollow guide column. A threaded moving frame is threadedly connected to the outer circumference of the threaded rod. The threaded moving frame is slidably disposed inside the hollow guide column. A square baffle is fixedly installed at the bottom of the threaded moving frame. The square baffle is slidably disposed inside the constant temperature tank.

[0006] Preferably, the vertical inner wall of the constant temperature tank is provided with a groove for providing stable displacement space, the two sides of the square baffle are connected with slide rails for cooperating with the groove, and the inside of the square baffle is fixedly installed with an annular frame for supporting stable rotation space.

[0007] Preferably, a hollow rotating column is rotatably installed inside the annular frame, and hollow connecting columns are connected to both sides of the hollow rotating column. The two hollow connecting columns are rotatably arranged on both sides of the annular frame. The ends of the hollow connecting columns are provided with conical grooves for increasing liquid flow, and multiple turbulence fins are installed on the outer periphery of the hollow connecting columns for contacting the liquid and driving the hollow connecting columns to rotate.

[0008] Preferably, the bottom of the square spoiler is provided with a double circular limiting groove for providing movement space, and the inner top wall of the double circular limiting groove is connected to two springs for providing thrust, and the ends of the two springs are connected to a double circular moving plate.

[0009] Preferably, the double-circle moving plate is slidably disposed inside the double-circle limiting groove, and the bottom of the double-circle moving plate is connected to two connecting rods for support, and the bottom of the two connecting rods is equipped with a cleaning scraper for cleaning the bottom wall of the constant temperature tank.

[0010] Preferably, the side of the constant temperature tank is connected to a connecting pipe, and the end of the connecting pipe away from the constant temperature tank is connected to a heating tank. The top of the heating tank is connected to a water inlet pipe for external liquid to enter. The bottom of the heating tank is equipped with a photovoltaic support frame for supporting the heating tank, and two photovoltaic panels for heating the liquid inside the heating tank are symmetrically installed on the top of the photovoltaic support frame.

[0011] Preferably, the inner bottom wall of the thermostatic tank is provided with multiple guide grooves to facilitate liquid outflow, and the outer periphery of the thermostatic tank is connected to multiple water outlet pipes.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This temperature-controlled drinking water system with automatic cleaning function benefits from a moving mechanism that uses a drive motor to rotate a threaded rod. This mechanism allows the threaded moving frame to slide horizontally along a hollow guide column, which in turn drives a square baffle to move horizontally left and right within the temperature-controlled container. Combined with the guiding action of the slide rails and grooves, this ensures smooth and complete turbulence throughout the container. Simultaneously, the annular frame inside the square baffle supports the hollow rotating column and the hollow connecting columns on both sides. The conical groove expands the liquid contact area, and the interaction between the baffle fins and the liquid drives the hollow connecting columns to rotate. This creates a dual effect of "horizontal reciprocating turbulence + rotational turbulence," significantly improving water circulation efficiency, completely eliminating cleaning dead zones, preventing water temperature stratification, ensuring the cleaning solution evenly covers all areas within the container, improving temperature control accuracy, reducing dirt and bacterial residue, ensuring drinking water safety, and optimizing the user experience.

[0013] This temperature-controlled drinking water system with automatic cleaning function benefits from the structure of the cleaning scraper. When the square baffle moves horizontally, the springs in the double-circle limiting grooves continuously apply downward force to the double-circle moving plate, causing the connecting rod to drive the cleaning scraper to fit tightly against the bottom wall of the temperature-controlled tank. The scraper slides left and right synchronously with the square baffle, efficiently scraping away attached scale and impurities. Simultaneously, the guide channels on the bottom wall of the temperature-controlled tank guide the scraped impurities and liquid to quickly converge into the outlet pipe for discharge, preventing impurities from accumulating and affecting system operation. This mechanical cleaning reduces bacterial growth and ensures smooth water flow, further improving drinking water quality and extending equipment lifespan. Furthermore, it eliminates the need for manual disassembly and cleaning, reducing maintenance costs and enhancing ease of use. Attached Figure Description

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] like Figures 1 to 5 The constant temperature drinking water system shown includes a constant temperature tank 2 for storing constant temperature water. A hollow guide column 201 for limiting movement displacement is fixedly installed on the top of the constant temperature tank 2, and a drive motor 202 for driving is installed on the side of the hollow guide column 201. The output shaft of the drive motor 202 is connected to a threaded rod 203 via a coupling. The threaded rod 203 is rotatably mounted inside the hollow guide column 201. A threaded moving frame 204 is threadedly connected to the outer circumference of the threaded rod 203. The threaded moving frame 204 is slidably mounted inside the hollow guide column 201. A square baffle 205 is fixedly installed at the bottom of the threaded moving frame 204. The square baffle 205 is slidably mounted inside the constant temperature tank 2.

[0020] The vertical inner wall of the constant temperature tank 2 is provided with a groove 206 for providing stable displacement space. A square baffle 205 has slide rails 207 connected to both sides for engaging with the groove 206. An annular frame 3 for supporting stable rotation space is fixedly installed inside the square baffle 205. A hollow rotating column 301 is rotatably installed inside the annular frame 3. Hollow connecting columns 303 are connected to both sides of the hollow rotating column 301. The two hollow connecting columns 303 are rotatably positioned on both sides of the annular frame 3. The end of 3 is provided with a conical groove 302 for increasing liquid flow. Multiple turbulence fins 304 are installed on the outer periphery of the hollow connecting column 303 for contacting the liquid and driving the hollow connecting column 303 to rotate. The drive motor 202 on the side of the hollow guide column 201 drives the internal threaded rod 203 to rotate through the coupling. The threaded moving frame 204, which is threadedly connected to the threaded rod 203, slides horizontally along the inside of the hollow guide column 201, thereby driving the square turbulence plate 205 at the bottom to move horizontally left and right in the constant temperature tank 2. The slide rails 207 on both sides of the square baffle 205 are precisely matched with the slide grooves 206 on the vertical inner wall of the constant temperature tank 2 to ensure smooth horizontal movement without deviation. At the same time, the annular frame 3 inside the square baffle 205 provides stable support for the hollow rotating column 301. The hollow rotating column 301 rotates synchronously with the liquid flow. The conical grooves 302 at the ends of the hollow connecting columns 303 on both sides expand the liquid contact area. After the multiple baffle fins 304 on the outer periphery fully contact the liquid, they further drive the hollow connecting column 303 to rotate, realizing all-round stirring of the liquid in the constant temperature tank 2 and effectively avoiding uneven local water temperature.

[0021] The bottom of the square spoiler 205 is provided with a double circular limiting groove 4 for providing movement space. The inner top wall of the double circular limiting groove 4 is connected to two springs 401 for providing thrust. The ends of the two springs 401 are connected to a double circular moving plate 402. The double circular moving plate 402 is slidably disposed inside the double circular limiting groove 4. The bottom of the double circular moving plate 402 is connected to two connecting rods 403 for support. The bottom of the two connecting rods 403 is equipped with a cleaning scraper 404 for cleaning the inner bottom wall of the constant temperature tank 2. When the square spoiler 205 moves horizontally left and right, the two springs 401 on the inner top wall of the bottom double circular limiting groove 4 continuously apply a downward thrust to the double circular moving plate 402, so that the double circular moving plate 402 drives the cleaning scraper 404 to tightly adhere to the inner bottom wall of the constant temperature tank 2 through the two connecting rods 403. The horizontal displacement of the square baffle 205 synchronously drives the cleaning scraper 404 to slide left and right on the inner bottom wall, thoroughly scraping away the attached scale and impurities. The scraped impurities flow with the liquid and are collected through the guide channel 5 to the outlet pipe 501 for discharge, which not only ensures the cleanliness of the effluent water quality, but also avoids the accumulation of impurities from affecting the normal operation of the system.

[0022] A connecting pipe 104 is connected to the side of the constant temperature tank 2. The end of the connecting pipe 104 away from the constant temperature tank 2 is connected to the heating tank 102. The top of the heating tank 102 is connected to a water inlet pipe 103 for external liquid to enter. A photovoltaic support frame 1 is installed at the bottom of the heating tank 102 to support the heating tank 102. Two photovoltaic panels 101 for heating the liquid inside the heating tank 102 are symmetrically installed on the top of the photovoltaic support frame 1. The inner bottom wall of the constant temperature tank 2 is provided with multiple guide grooves 5 to facilitate the outflow of liquid. Multiple water outlet pipes 501 are connected to the outer periphery of the constant temperature tank 2. External liquid enters the heating tank 102 through the water inlet pipe 103. The two photovoltaic panels 101 on the top of the photovoltaic support frame 1 provide heat to the heating tank 102, so that the internal liquid is heated to the set constant temperature and then flows into the constant temperature tank 2 for storage through the connecting pipe 104. The thermostatic tank 2 provides users with constant temperature water supply through multiple water outlet pipes 501 connected to the outer periphery, while multiple guide grooves 5 on the inner bottom wall can guide the liquid to quickly converge to the water outlet pipes 501, avoiding liquid residue accumulation.

[0023] This constant-temperature drinking water system with automatic cleaning function contains necessary intelligent components, such as: a temperature sensor embedded in the heating tank 102, which monitors the liquid temperature in real time and links it with the heating efficiency of the photovoltaic panel 101. The controller automatically adjusts the energy output of the photovoltaic panel 101 to ensure that the liquid in the heating tank 102 is accurately maintained in a constant temperature range suitable for the growth of livestock and poultry (such as 18-22℃ for piglets and 20-25℃ for fattening pigs), avoiding errors from manual adjustment; at the same time, a timer control unit is configured for the drive motor 202, which can preset the turbulence cleaning cycle according to the usage frequency (such as 3 times a day, 15 minutes each time), and automatically start the horizontal movement and rotation of the square turbulence plate 205 to turbulence, so that regular cleaning can be completed without manual supervision. In terms of emergency protection, liquid level sensors are installed in the constant temperature tank 2 and the heating tank 102. When the liquid level is lower than the safety threshold, the drive motor 202 and the heating function of the photovoltaic panel 101 are automatically shut off to prevent dry running and damage to components. Pressure sensors are installed at the connecting pipe 104 and the water outlet pipe 501. If the pipeline pressure is abnormal due to impurities, an alarm will be triggered immediately and the water supply will be suspended, making it easy for operators to clean up in time. The drive motor 202 has a built-in overload protection device. When the threaded rod 203 and the threaded moving frame 204 are stuck, the power will be automatically cut off to prevent the motor from burning out and extend the service life of the equipment. The necessary intelligent components are not the innovative direction of this constant temperature drinking water system with automatic cleaning function, so they will not be described in detail.

[0024] To avoid the impact of various factors on the normal operation of the system, I will explain in detail the safeguards from six core dimensions: environmental adaptation, maintenance, sealing and protection, material selection, component matching, and personnel operation, combined with the characteristics of each component, to ensure the stable operation of the system. Regarding environmental adaptation, the deployment needs to be optimized for the characteristics of use scenarios such as livestock and poultry farming, including dust, humidity, and large temperature differences. The photovoltaic support frame 1 should be installed in a well-ventilated, dry, and unobstructed area to prevent the photovoltaic panel 101 from being covered by dust and livestock and poultry manure, which would affect its heat absorption efficiency. At the same time, the surface of the photovoltaic panel 101 should be cleaned regularly to ensure it can stably provide heat to the heating tank 102. The constant temperature tank 2 and the heating tank 102 should be kept away from areas with dense livestock and poultry activity to prevent collisions that could deform the slide rail 206 or slide rail 207, or damage the connecting pipe 104. The ground where they are placed must be flat to prevent the square baffle 205 from getting stuck due to tilting, and to avoid uneven adhesion of the cleaning scraper 404. For environments with extreme temperature differences, an insulation layer can be wrapped around the outside of the constant temperature tank 2 and the heating tank 102 to reduce heat loss, avoid water temperature fluctuations caused by sudden changes in ambient temperature, ensure the synergistic effect of heating of photovoltaic panel 101 and insulation of constant temperature tank 2, and prevent water circulation and constant temperature accuracy from being affected by improper environmental adaptation.

[0025] Maintenance requires a regular inspection mechanism to ensure the proper functioning of all components. Regularly check the operating status of the drive motor 202, clean dust from its surface, and add lubricating oil to ensure smooth transmission between the coupling and threaded rod 203, preventing motor jamming that could prevent the square baffle 205 from moving horizontally. Check the elasticity of the spring 401 weekly; replace it promptly if elasticity is diminished or deformed to ensure the double-circular moving plate 402 can drive the cleaning scraper 404 to tightly adhere to the inner bottom wall of the thermostatic tank 2, preventing incomplete cleaning due to spring failure. Clean the flow channel 5 and the inside of the outlet pipe 501 monthly to remove accumulated impurities and prevent pipe blockage affecting liquid flow. Also check the unobstructed flow of the connecting pipe 104 to prevent scale buildup from hindering the flow of thermostatic water to the thermostatic tank 2. Regularly verify the heating efficiency of the photovoltaic panel 101 to ensure the heating tank 102 can heat the liquid to the set constant temperature, preventing insufficient heating from exacerbating water temperature stratification problems.

[0026] In terms of sealing and protection, the sealing performance of key parts needs to be strengthened to prevent water leakage and contamination. Corrosion-resistant sealing gaskets are used at the connection between the heating tank 102 and the water inlet pipe 103 and the connecting pipe 104. A double-layer sealing structure is installed at the interface between the constant temperature tank 2 and the connecting pipe 104 and the water outlet pipe 501 to prevent liquid leakage from causing short circuit damage to the photovoltaic support frame 1 and the drive motor 202. A dustproof sealing cover is installed on the top of the hollow guide column 201 to prevent dust from entering the interior and affecting the threaded fit between the threaded rod 203 and the threaded moving frame 204, and to avoid jamming or wear. A sealed bearing is installed at the rotating connection between the ring frame 3 and the hollow connecting column 303 to ensure smooth rotation and prevent liquid from seeping in and causing internal corrosion, ensuring that the dual effect of "horizontal reciprocating disturbance + rotational turbulence" is not affected. A waterproof sealing ring is set at the opening of the double circular limit groove 4 to prevent liquid from entering the interior and causing the spring 401 to rust and fail, and to ensure the stable thrust of the cleaning scraper 404.

[0027] Material selection must consider corrosion resistance, wear resistance, and compatibility. The constant temperature tank 2, heating tank 102, connecting pipe 104, and water outlet pipe 501 are all made of food-grade 304 stainless steel, which not only resists corrosion from acidic and alkaline substances in the livestock and poultry drinking water environment, but also prevents the release of harmful substances from the materials that could affect drinking water safety. The square baffle 205, hollow rotating column 303, and hollow connecting column 303 are made of high-strength engineering plastic, which reduces weight while improving wear resistance and extending the service life of the sliding groove 206, sliding rail 207, and ring frame 3. The cleaning scraper 404 is made of elastic and wear-resistant rubber, which ensures good contact with the inner bottom wall of the constant temperature tank 2, avoids scratching the tank wall and causing impurities to adhere, and enhances the scraping effect of scale. The spring 401 is made of stainless steel, which improves the resistance to rust and ensures that it maintains stable elasticity in a humid environment for a long time, preventing component failure due to material aging.

[0028] The precision of component fit is crucial for the normal operation of the system and must be controlled from both installation and calibration aspects. During installation, ensure precise thread engagement between the threaded rod 203 and the threaded moving frame 204, and ensure the hollow guide column 201 is smooth and burr-free to prevent jamming when the threaded moving frame 204 slides. Adjust the clearance between the slide rail 207 and the slide groove 206 to ensure smooth and unbiased horizontal movement of the square baffle 205, preventing uneven turbulence due to excessive clearance or accelerated wear due to insufficient clearance. Calibrate the rotational fit between the hollow connecting column 303 and the annular frame 3 to ensure the baffle fins 304 can rotate flexibly after contacting the liquid, preventing rotational baffle failure due to installation deviations. Ensure uniform adhesion between the cleaning scraper 404 and the inner bottom wall of the constant temperature tank 2, compensating for installation errors by adjusting the length of the connecting rod 403 to prevent cleaning dead zones due to uneven adhesion. At the same time, regularly check the tightness of the connections of each component to avoid loosening of threads and displacement of components due to vibration, and ensure the transmission coordination of core components such as drive motor 202, threaded rod 203, and square spoiler 205.

[0029] In terms of personnel operation, standardized procedures must be followed to avoid human error affecting system operation. Operators must undergo professional training and be familiar with the functions and operating procedures of each component of the system. Before starting, check whether the photovoltaic panel 101 is clean, whether all pipe interfaces are properly sealed, and whether the drive motor 202 is properly powered. During operation, it is forbidden to arbitrarily adjust the operating parameters of the drive motor 202 to avoid overloading and damaging the threaded rod 203 due to excessive speed or causing excessive impact from the movement of the square baffle 205. When adding cleaning fluid, the amount and concentration must be controlled to avoid corrosion of seals and metal parts. At the same time, ensure that the liquid is injected into the heating tank 102 at a uniform speed through the water inlet pipe 103 to prevent liquid overflow or insufficient heating due to excessive injection. After the system is shut down, the water inlet valve must be closed and the residual liquid in the pipes must be drained, especially in low-temperature environments, the pipes must be completely drained to prevent freezing and cracking, which would affect subsequent use. Non-professionals are prohibited from disassembling core components such as the hollow guide column 201 and the ring frame 3. When performing maintenance, the power must be disconnected to prevent electric shock or damage to components. Ensure that personnel operation does not affect the sealing performance, component fitting accuracy, and normal operation of the system.

[0030] Working principle This constant-temperature drinking water system with automatic cleaning function works as follows: First, external liquid enters the heating tank 102 through the inlet pipe 103. Two photovoltaic panels 101 on the top of the photovoltaic support frame 1 provide heat to the heating tank 102, heating the internal liquid to a set constant temperature. Then, the liquid flows into the constant-temperature tank 2 for storage through the connecting pipe 104. During water supply, multiple guide channels 5 on the bottom wall of the constant-temperature tank 2 guide the liquid to quickly converge to multiple outlet pipes 501 connected to the outer periphery, ensuring a stable supply of constant-temperature water to the user. Simultaneously, the drive motor 202 on the side of the hollow guide column 201 drives the internal threaded rod 203 to rotate via a coupling. The threaded moving frame 204, threadedly connected to the threaded rod 203, slides horizontally along the inside of the hollow guide column 201, causing the square baffle 205 at the bottom to move horizontally left and right within the constant-temperature tank 2. The slide rails 207 on both sides of the square baffle 205 precisely engage with the slide grooves 206 on the vertical inner wall of the constant-temperature tank 2, ensuring smooth and unbiased movement. The annular frame 3 inside the square baffle 205 supports the hollow rotating column 301. The conical grooves 302 at the ends of the hollow connecting columns 303 on both sides expand the liquid contact area. After the multiple baffle fins 304 on the outer periphery fully contact the liquid, they drive the hollow connecting columns 303 to rotate, realizing all-round stirring of the liquid and avoiding uneven local water temperature. During the horizontal movement of the square baffle 205, the two springs 401 on the top wall of the double circular limiting groove 4 at the bottom continuously apply downward thrust to the double circular moving plate 402, so that the double circular moving plate 402 drives the cleaning scraper 404 to closely adhere to the inner bottom wall of the constant temperature tank 2 through the two connecting rods 403. It slides left and right synchronously with the square baffle 205 to thoroughly scrape off the attached scale and impurities. The impurities are collected with the liquid through the guide channel 5 and discharged through the outlet pipe 501, which not only ensures the cleanliness of the water output, but also avoids the accumulation of impurities affecting the operation of the system.
