Description

Technical Field

[0001] This utility model relates to the field of poultry farming technology, and in particular to a water supply system for poultry farming. Background Technology

[0002] In poultry farming, a stable water supply is crucial for ensuring healthy growth and improving farming efficiency. This is especially true for poultry with specific physiological characteristics, such as the Beijing duck, where water conditions directly affect feed intake, digestion and absorption, and immune levels. Currently, large-scale poultry farms generally use centralized water supply lines, but existing water supply equipment still has many shortcomings in terms of adaptability, controllability, and hygiene.

[0003] First, existing water supply systems struggle to achieve precise and stable water temperature control. During seasonal changes or in environments with significant diurnal temperature variations, the water temperature within the pipes fluctuates with the ambient temperature. In winter, excessively low water temperatures lead to decreased water consumption, indigestion, and increased energy expenditure in poultry; conversely, excessively high water temperatures in summer inhibit drinking, thus affecting feed intake and growth rates. While some farms have attempted to use heating devices, most lack closed-loop temperature control and effective insulation measures, resulting in high energy consumption and poor water temperature stability, failing to meet the continuous demand for suitable drinking temperatures for poultry, especially chicks and adults at different stages.

[0004] Furthermore, poultry drinking water hygiene is a prominent issue. Water sources often contain sediment, microorganisms, and organic pollutants. If supplied directly without effective treatment, this can easily lead to clogged drinkers, bacterial growth, and intestinal diseases in poultry, increasing medication costs and farming risks. Although some water supply equipment has added filtration systems, the filtration stages are often limited, and in particular, there is a lack of effective methods to kill microorganisms, failing to comprehensively guarantee drinking water safety.

This invention achieves automated and precise regulation of the total water supply flow by setting up a flow regulation unit consisting of a flow controller, a flow regulating valve, and a flow sensor. The water supply flow can be flexibly set and adjusted according to changes in poultry house size, poultry age, and number, ensuring stable water pressure, meeting the needs of multiple drinkers operating simultaneously, avoiding water waste, and improving the intelligence level and efficiency of water line management.

[0017] Furthermore, this invention connects the water supply branch pipe to the main water supply pipe via a slidingly adjustable connection structure (first vertical pipe, second vertical pipe, fastening bolts, etc.). This allows the height of the water supply branch pipe to be flexibly and conveniently adjusted according to the height changes of poultry during their growth stages (e.g., chick stage, growth stage), thus ensuring that the waterer is always at the optimal height for poultry drinking, improving the adaptability and ease of use of the equipment. This invention also incorporates drain pipes and drain valves at key locations in the water storage unit, filtration unit, and connecting pipelines.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] The purpose of this invention is to provide a water supply system for poultry farming to solve the problems existing in the prior art and improve the water supply quality for poultry farming.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, this embodiment provides a water supply system for poultry farming, mainly used in large-scale farms, especially to provide stable, clean, and appropriately warm drinking water for poultry such as Beijing ducks. The system forms a complete closed loop from source water treatment to end-point water supply.

[0025] The poultry farming water supply system of this embodiment specifically includes the following structure: 1. Water storage unit The water storage unit is a cylindrical vertical water tank 1 made of food-grade stainless steel, with a volume that can be configured according to the scale of aquaculture, for example, 5 cubic meters. A first water inlet 11 is located at the center of the top of the water tank 1 for connecting to an external water source (such as tap water or pre-sedimented well water). The bottom of the water tank 1 has a hemispherical curved surface and a first drain pipe 12 is welded onto it. A first drain valve 13 (such as a ball valve) is installed on the first drain pipe 12. The water tank 1 serves to store and perform preliminary sedimentation, allowing some large particles of impurities in the water to settle. The sludge deposited at the bottom of the tank can be discharged by periodically opening the first drain valve 13.

[0026] 2. Filter unit The filter unit includes a vertically placed cylindrical first housing 2, which is made of UPVC or stainless steel. The top of the first housing 2 is connected to the water outlet at the lower side wall of the water storage tank 1 via a first connecting pipe 3. A manual valve can be installed on the first connecting pipe 3 to control the water inlet.

[0027] Inside the first housing 2, from top to bottom, there are a pre-filter layer 21, a fine filter layer 22, and a sterilization layer 23. The layers are separated by perforated partitions for easy maintenance and replacement.

[0028] The primary filter layer 21 uses a 304 stainless steel filter screen with a pore size of 1mm, which is folded or laid flat to mainly intercept visible impurities such as hair and larger sand particles in the water.

[0029] The fine filtration layer 22 uses columnar activated carbon filter media with a particle size of 2mm-3mm, and the filling height is about one-third of the shell height. It is used to adsorb tiny suspended solids, colloids, organic residues and odors in the water, and improve the taste of the water.

[0030] The sterilization layer 23 is equipped with one or more low-pressure mercury vapor ultraviolet germicidal lamps, preferably with a power of 30W. The lamp tubes are encased in quartz glass sleeves, allowing water to receive direct ultraviolet radiation as it flows through, effectively killing bacteria, viruses, and other microorganisms in the water, achieving a sterilization rate of over 99%. The power cord of the ultraviolet germicidal lamp is sealed and led out from the side wall of the first housing 2, connected to an external ballast and power supply.

[0031] The bottom end of the first housing 2 is connected to a second drain pipe 24, and a second drain valve 25 is installed on the second drain pipe 24 for periodically flushing and discharging impurities and failed filter media accumulated in the filter unit.

[0032] 3. Constant temperature heating unit The constant temperature heating unit is used to heat and maintain a constant temperature for the purified cold water. It includes a water pipe 4, which is a straight pipe made of copper or stainless steel to facilitate heat conduction. An electric heating element 41, an armored resistance heating wire, is tightly spirally wound around the outer wall of the water pipe 4. A temperature sensor 42, such as a PT100 platinum resistance thermometer, is installed inside the water flow channel of the water pipe 4. The temperature sensor 42 is electrically connected to an external temperature controller 43 (such as a PID temperature controller) via a signal line. The power supply circuit for the electric heating element 41 is controlled by the temperature controller 43. An insulation layer 44, made of polyurethane foam, is completely wrapped around the outside of the water pipe 4 and the electric heating element 41. The insulation layer 44 is 5cm thick and is formed by molding or using a prefabricated shell to effectively reduce heat loss.

[0033] The inlet of the water pipe 4 is connected to the outlet at the bottom of the first housing 2 via the second connecting pipe 5. At the lowest point of the second connecting pipe 5, a third drain pipe 51 is also provided, on which a third drain valve 52 is installed to drain the water in the pipe or flush out sediment.

[0034] 4. Flow regulating unit and water supply pipeline The outlet of water pipe 4 is connected to the main water supply pipe 6. Water flows into the main water supply pipe 6 after being heated and kept at a constant temperature. The flow regulation unit includes a flow controller 71, a flow regulating valve 72, and a flow sensor 73. The flow regulating valve 72 (an electric ball valve is used in this embodiment) is installed on the main water supply pipe 6. The flow sensor 73 (an electromagnetic flow sensor is used in this embodiment) is installed on the main water supply pipe 6 and is located downstream of the flow regulating valve 72 (along the water flow direction). The flow sensor 73 is signal-connected to the flow controller 71 to monitor the water flow in the pipe in real time. The flow regulating valve 72 is electrically connected to the flow controller 71. The flow controller 71 (which can be a PLC or a dedicated control module) can preset the required flow parameters. It can compare the real-time flow signal fed back by the flow sensor 73 with the preset value and output a control signal through algorithms such as PID to dynamically adjust the opening of the flow regulating valve 72, thereby achieving accurate and stable control of the total outflow of the entire system.

[0035] 5. Height-adjustable water supply branch pipe The end of the main water supply pipe 6 furthest from the constant temperature heating unit (i.e., the downstream end) is a first vertical pipe 61. The side wall of the first vertical pipe 61 is engraved with scale lines distributed in the vertical direction (not shown in the figure), and the scale value indicates the height above the ground.

[0036] A second vertical pipe 81 is connected to the top of the water supply branch pipe 8. The inner diameter of the second vertical pipe 81 is slightly larger than the outer diameter of the first vertical pipe 61, allowing the second vertical pipe 81 to slidably fit over the outside of the first vertical pipe 61. A dynamic seal is achieved between the inner wall of the second vertical pipe 81 and the outer wall of the first vertical pipe 61 through a sealing assembly. Specifically, a sleeve 82 is fixedly fitted (e.g., glued or interference-fitted) inside the top of the second vertical pipe 81. A ring-shaped, inwardly protruding limiting step is machined on the inner wall of the sleeve 82. An annular waterproof rubber ring 83 (made of food-grade silicone) is partially placed on this annular limiting step, and the other part is clamped between the annular limiting step and the top end face of the second vertical pipe 81. When the second vertical pipe 81 is fitted onto the first vertical pipe 61, the inner ring of the waterproof rubber ring 83 fits tightly against the outer wall of the first vertical pipe 61, forming a sliding seal that prevents leakage while allowing relative sliding between the two.

[0037] A threaded hole is provided on the side wall of the second vertical pipe 81, and a fastening bolt 84 is threaded into this hole. When it is necessary to adjust the height of the water supply branch pipe 8, first loosen the fastening bolt 84 so that the end of the bolt is no longer in contact with the outer wall of the first vertical pipe 61. Then, drag the second vertical pipe 81 and the connected water supply branch pipe 8 up and down. By observing the scale lines, the height can be precisely adjusted to the required height for different growth stages such as ducklings and adult ducks. After adjustment, tighten the fastening bolt 84 so that its end is firmly pressed against the outer wall of the first vertical pipe 61. The friction force is used to fix the relative position of the second vertical pipe 81 and the first vertical pipe 61, thereby locking the height.

[0038] 6. Point-of-use water dispensers On the water supply branch pipe 8, multiple poultry drinkers 9, such as nipple drinkers or cup drinkers, are installed at intervals (e.g., one every 1 meter) along its length. The specific number and spacing of the poultry drinkers 9 are determined according to the poultry breed and stocking density.

[0039] The specific working principle of the poultry farming water supply system in this embodiment is as follows: External water enters the storage tank 1 through the first inlet 11. After preliminary sedimentation, it enters the filtration unit through the first connecting pipe 3. The water flows sequentially through the coarse filtration of the primary filter layer 21, the adsorption purification of the fine filter layer 22, and the ultraviolet disinfection of the sterilization layer 23, becoming clean water. The clean water enters the water pipe 4 of the constant temperature heating unit through the second connecting pipe 5. The temperature sensor 42 detects the water temperature in the water pipe 4 in real time and transmits the signal to the temperature controller 43. The temperature controller 43 compares the detected value with the set value (for Beijing ducks, the water temperature set value is usually set to 18-25℃) and controls the start and stop of the electric heating tube 41 to stabilize the water temperature within the set range, while the insulation layer 44 reduces heat loss. The heated constant temperature water enters the main water supply pipe 6. The flow sensor 73 detects the real-time flow rate, and the flow controller 71 adjusts the opening of the electric ball valve according to the set flow rate to stabilize the system output flow rate. Finally, the constant temperature, clean, and stable flow water is distributed to each poultry drinker 9 through the height-adjustable water supply branch pipe 8 for the poultry to drink.

[0040] The poultry farming water supply system in this embodiment integrates filtration, sterilization, constant temperature heating, flow regulation, and high adaptability functions. It has a high degree of automation and can effectively ensure the quality, temperature, and accessibility of drinking water for poultry, thereby improving farming efficiency.

[0041] As an optional implementation, the temperature controller of the constant temperature heating unit and the flow controller of the flow regulating unit share a PLC controller to achieve centralized control.

[0042] When used for Beijing duck farming, the corresponding flow parameters are set through the PLC controller according to the growth stage of the Beijing ducks: 0.5-1L / min for ducklings, 1-1.5L / min for young ducks, and 1.5-2L / min for adult ducks. The height of the drinker is adjusted according to the growth stage of the Beijing ducks: 5-8cm for ducklings, 8-12cm for young ducks, and 12-15cm for adult ducks. The poultry drinker is a nipple drinker, with one drinker configured for every 10 Beijing ducks.
