Description

Technical Field

[0001] This invention relates to the field of livestock and poultry breeding equipment, and in particular to an eco-friendly cattle shed. Background Technology

[0002] Traditional cattle sheds often suffer from numerous problems. Large amounts of manure accumulate and are discharged directly without effective treatment, polluting soil and water sources (such as groundwater and surrounding rivers) with nitrogen and phosphorus, leading to eutrophication. Simultaneously, manure fermentation produces harmful gases such as ammonia and hydrogen sulfide, affecting air quality within the shed and spreading to the surrounding environment, harming human health and ecological balance. The organic matter, nitrogen, and phosphorus in the manure are not utilized; they are discarded directly as pollutants instead of being converted into fertilizer or energy for agricultural production. Furthermore, traditional cattle sheds rely heavily on external energy sources (such as electricity and coal) for heating and lighting, resulting in high energy consumption and costs. In addition, pest control in cattle sheds relies on manual labor, which is time-consuming, labor-intensive, and prone to incomplete disinfection. Therefore, this invention proposes an ecological cattle shed. Summary of the Invention

Detailed Implementation

[0017] like Figure 1-13 As shown, an eco-friendly cattle shed includes a cattle shed 1. Several chimneys 3 are installed on the roof of the cattle shed 1, which can be used to exhaust smoke during winter heating and for daily ventilation. The roof of the cattle shed 3 is equipped with skylights 12, which are opened / closed by an automatic opening device 13. The skylights 12 are made of transparent materials, such as glass, which not only do not affect lighting but also provide some insulation.

[0018] The front of the cattle shed 1 is equipped with a door 4, the number of which can be selected according to actual needs. Several windows 2 are installed above the door 4 for ventilation and lighting. Several ventilation windows are installed on both the left and right side walls of the cattle shed 1 for ventilation. The interior of the cattle shed 1 is symmetrically divided into several spaces by partition walls 8, facilitating separate feeding, such as feeding calves and cows together, feeding adult cattle together, and feeding sick cattle separately, thus simplifying management. Fences 10 are symmetrically installed in the middle, with a central walkway 15 between the fences 10 for personnel movement. A main sewer 14 is installed underground in the central walkway 15, and an auxiliary sewer 16 is installed underground in the middle section between the partition walls 8 and the cattle shed 1.

[0019] The main sewer 14 and the auxiliary sewer 16 have the same structure and are both connected to the symmetrically distributed drainage channels 21 located above them. The main sewer 14 has a material stacking pipe 20 and a sewage discharge pipe 19 symmetrically installed on its left and right sides. The main sewer 14 is connected to the auxiliary sewer 16 through a long pipe 17 on its left and right sides. The end of the auxiliary sewer 16 away from the long pipe 17 is connected to a short pipe 18. The short pipe 18 on the left side is connected to the material stacking pipe 20, and the short pipe 18 on the right side is connected to the sewage discharge pipe 19.

[0020] Specifically, during the cleaning of the cattle shed, after most of the manure, feed, and debris have been removed, some manure and other materials that are difficult to clean remain on the floor of cattle shed 1. At this time, they are flushed into the drainage channel 21 by high-pressure water pipes, and then converge into the main drainage channel 14 and the auxiliary drainage channel 16. At this point, the gate 23 on one side of the main drainage channel 14 connecting to the material stacking pipe 20, as well as the gate 23 on one side of the short pipe 18 of the left auxiliary drainage channel 16 and the long pipe 17 of the right auxiliary drainage channel 16, are opened. The water carries the manure and other organic matter into the material stacking pipe 20, and finally into the biogas power station 11 for fermentation. After the cattle shed cleaning is completed, the main drainage channel is closed. Gate 23 on one side of the main sewer 14 connects to the material stacking pipe 20, as well as gate 23 on one side of the left auxiliary sewer 16 short pipe 18 and the right auxiliary sewer 16 long pipe 17. Gate 23 on one side of the main sewer 14 connects to the sewage pipe 19, as well as gate 23 on one side of the left auxiliary sewer 16 long pipe 7 and the right auxiliary sewer 16 short pipe 18. At the same time, the atomizing nozzles on the spray pipe 6 are opened to spray disinfectant liquid and carry out comprehensive disinfection of the cattle shed 1. After the disinfection is completed, all doors and windows are opened, and the cattle shed 1 is rinsed with water pipes. The sewage containing disinfectant liquid enters the treatment plant for centralized treatment from the sewage pipe 19 to avoid the disinfectant liquid from polluting the soil and to maintain the ecological balance.

[0021] In the aforementioned pipeline, the bends / diameter changes in the long pipe 17 / short pipe 18 are prone to clogging. Therefore, an anti-clogging mechanism can be installed according to the actual situation. The anti-clogging mechanism includes a connecting pipe 24 located on one side of the bend / diameter change. Since the pipeline uses a smooth inner wall material, such as PE or PVC, to reduce the adhesion of dirt, the connecting pipe 24 is integrally injection molded from the same material, and its upper end is connected to a flange 25 via threads (a sealing ring is provided between the two). A high-pressure water pipe 26 and a flow sensor 27 are installed on the flange 25 (the connection also needs to be sealed, such as with a sealing ring). The outlet end of the high-pressure water pipe 26 and the detection end of the flow sensor 27 both pass through the flange 25 and are located inside the long pipe 17 / short pipe 18. The sensor housing is made of 316 stainless steel to avoid corrosion or malfunction due to cow dung liquid. The flow sensor 27 monitors the changes in liquid flow rate and pressure in the pipeline. When dirt accumulates, the pipe cross-section shrinks, the flow rate decreases, and the pressure increases, generating an abnormal signal. Based on abnormal signals, the control system activates the high-pressure pump on the high-pressure water pipe 26 to spray high-pressure water onto the blockage, peeling off attached cow dung residue, fibers, and other contaminants and flushing them out with the water flow, preventing them from accumulating and solidifying. Specifically, the outlet end of the high-pressure water pipe 26 has a 40°-50° bend, and the outlet port faces the bend / diameter change point of the long pipe 17 / short pipe 18. This not only allows for precise high-pressure water flushing of the blockage but also prevents cow dung residue, fibers, and other contaminants from accumulating in the high-pressure water pipe 26.

[0022] The end of the stacking pipe 20 furthest from the cowshed 1 is connected to the biogas power station 11, which is as follows: Figure 3 As shown, livestock manure, straw, and other organic-rich raw materials are fermented to produce biogas, mainly composed of methane (50%-70%) and carbon dioxide (30%-50%), while also generating biogas residue and biogas slurry (organic fertilizer). After purification, the biogas is mixed with air in a specific ratio and then fed into the engine cylinder. Ignition via spark plugs (internal combustion engine) or high-temperature gas combustion (gas turbine) drives the fuel combustion. The resulting high-temperature, high-pressure gas drives the piston (or turbine), which in turn rotates the generator rotor, cutting magnetic field lines to generate electricity. A portion of this electricity is used in the cattle shed, and the remainder is fed into the power grid. Furthermore, the engine generates a significant amount of waste heat (exhaust gas, cooling water heat), which can be recovered through waste heat boilers, heat exchangers, and other equipment. This waste heat can be used to heat the biogas digester (maintaining fermentation temperature), provide heating, or produce hot water, thus improving the overall energy utilization rate.

[0023] The biogas digesters produce biogas slurry (liquid, rich in soluble nutrients such as nitrogen, phosphorus, and potassium) and biogas residue (solid, containing organic matter and crude fiber) as byproducts during anaerobic fermentation. The biogas slurry is transported to pasture planting areas and applied directly to the soil via drip irrigation or sprinkler irrigation. In no-till farming, the biogas slurry not only provides nutrients for pasture (such as ryegrass and alfalfa), but its liquid properties also improve soil moisture, reduce energy consumption during cultivation, and avoid soil compaction problems caused by chemical fertilizers. Cow manure mixed with biogas residue undergoes further aerobic fermentation to reduce moisture and pathogen content, forming soft bedding material that can be reused in cattle sheds, reducing the consumption of traditional bedding materials such as sawdust and straw. Biogas residue and cow manure are rich in cellulose and lignin. After crushing and sterilization, they can be used as a cultivation substrate for mushrooms such as oyster mushrooms and button mushrooms, achieving a secondary cycle of "livestock-waste-planting." Furthermore, the mushroom residue after harvesting can be returned to the field or used as organic fertilizer.

[0024] The top of the cattle shed 1 is equipped with a support frame 5. Below the support frame 5, several pipes 7 support and install a spray pipe 6. At equal intervals at the bottom of the spray pipe 6, several atomizing nozzles are installed for disinfection, cooling, or cleaning. Water troughs 9 are installed on both sides of the partition wall 8 and on the inner sides of the left and right side walls of the cattle shed 1. Water pipe connectors are installed inside the cattle shed 1, with the other end of each connector connected to an external water source.

[0025] The pipe support 7 includes an upper clamp 701 and a lower clamp 702 symmetrically distributed vertically. One end of the upper clamp 701 and the lower clamp 702 are hinged together by a hinge shaft, and the other end is provided with a connecting hole 707. The connecting holes 707 are connected together by bolts. A central hole 703 is installed on the top of the upper clamp 701. A pressing mechanism is installed in the central hole. The pressing mechanism presses the spray pipe 6 against the inner side wall of the lower clamp 702.

[0026] The clamping mechanism includes a threaded rod 704, with an internal thread 708 installed in the central hole 704. After the threaded rod 704 passes through the central hole 704, a clamping plate 705 is installed. A rotating handle is installed at the end of the threaded rod 704 away from the clamping plate 705. By rotating the handle, according to the lead screw principle, the threaded rod 704 moves up and down, causing the clamping plate 705 to move up and down, thus satisfying the clamping operation of the spray pipe 6.

[0027] The clamping mechanism includes a slide rod 709, which slidably passes through the central hole 704 and is connected to a clamping plate 705. A spring 706 is sleeved on the slide rod 709 between the upper end of the clamping plate 705 and the inner wall of the upper clamp 701. A limiting rod is installed at the end of the slide rod 709 away from the clamping plate 705. In use, by pulling the limiting rod, the clamping plate 705 is engaged to brake the spray pipe 6. After releasing the limiting rod, the clamping plate 705 clamps the spray pipe 6 under the elastic action of the spring 706.

[0028] The water trough 9 includes a main body 901, the bottom of which is supported on the ground by a plurality of equally spaced support legs 903. A water outlet 902 is installed on one side of the bottom of the main body 901. An electric heating component is installed on the back of the main body 901, and a plurality of electric heating switches 904 are installed at the front of the main body 901 to control the switching of the electric heating component. The required power is supplied by the biogas power station 11. The electric heating component can prevent the water in the water trough 9 from freezing in cold weather, and can also adjust the water temperature (mainly by raising the temperature) according to the cattle's drinking water temperature requirements for the day.

[0029] The skylight 12 includes a mounting bracket 1201, which is connected to the window 1202 via a support mechanism. The window 1202 is opened by moving up and down via an automatic opening device 13.

[0030] The support mechanism includes a support component one located at the bottom of the skylight 12 and the mounting bracket 1201, a support component three located in the middle, and a support component two located at the top. The support assembly includes a hinge shaft 1204, and hinge rods 1203 are rotatably mounted on both ends of the hinge shaft 1204, which are symmetrically distributed vertically. The ends of the hinge rods 1203 away from the hinge shaft 1204 are respectively hinged to the frame of the window 1202 and the mounting bracket 1201. The second support component includes a second hinge shaft 1207, and two ends of the second hinge shaft 1207 are rotatably mounted with symmetrically distributed second hinge rods 1206. The ends of the second hinge rods 1206 away from the second hinge shaft 1207 are respectively hinged to the frame of the window 1202 and the mounting bracket 1201. The support assembly three includes symmetrically distributed support rods 1205. The support rods 1205 are designed with an inclination, and the two ends of the support rods 1205 are respectively hinged to the frame of the window 1202 and the mounting bracket 1201.

[0031] The length of hinge rod 1203 is greater than the length of hinge rod 1206, and when the hinge rod rotates, the hinge axis of its hinge connection moves inward, thus achieving an open state with a certain tilt angle relative to the mounting bracket 1201. Specifically, when the weather is fine, the window 1202 is fully open under the automatic opening device 13. At this time, there are gaps at the top and bottom between the window 1202 and the mounting bracket 1201 to allow air to pass through, improving ventilation. When it rains in summer, the automatic opening device 13 keeps the window 1202 in a half-open or slightly open state. At this time, the gap between the top of the window 1202 and the mounting bracket 1201 is small and close to a seamless state, while there is a gap at the bottom. The upper edge of the window 1202 forms a shield, preventing rainwater from splashing directly into the cowshed 1. Even in light rain, slight ventilation can be maintained to avoid stuffiness in the cowshed 1, thus achieving ventilation of the cowshed 1.

[0032] The automatic opening device 13 includes a top rod 1301 hinged to the skylight 12. A sector gear 1304 is integrally formed at the bottom of the top rod 1301. A crossbeam 1309 is rotatably mounted at the connection between the top rod 1301 and the sector gear 1304 via a rotating pin 1303. The sector gear 1304 meshes with a spur gear 1305. A rotating shaft is keyed to the center of the spur gear 1305. The rotating shaft passes through the crossbeam 1309 and is keyed to a bevel gear 1306. Wheel 1306 meshes with bevel gear 1307, which is fixedly connected to the shaft end of reversible motor 1308; the top of push rod 1301 is hinged to sunroof 12 via connecting pin 1302; a limiting block 1310 is sleeved around the outer periphery of spur gear 1305, which is fixedly connected to crossbeam 1309; a groove is provided on the side of limiting block 1310 near sector gear 1304, and the teeth of sector gear 1304 are located in the groove.

[0033] Specifically, the forward and reverse motor 1308 starts according to the window opening and closing command, the second bevel gear 1307 rotates, and the first bevel gear 1306 meshing with it rotates synchronously. Under the action of the rotating shaft, the spur gear 1305 rotates. Then, the spur gear 1305 drives the sector gear 1304 meshing with it to make an arc motion. Under the restriction of the rotating pin 1303, the top rod 1301 pushes the window 1202 to move up and down. Finally, under the linkage of the support mechanism, the window 1202 is opened (or closed) relative to the mounting bracket 1201, and the opening size is adjusted according to actual needs.

[0034] A drainage device 22 is installed inside the drainage channel 21. The drainage device 22 includes a water guide channel 2202 installed at an angle at the bottom to facilitate water flow. A filter plate 2201 is installed above the water guide channel 2202 to filter out larger impurities and prevent pipe blockage. Mounting legs 2203 are symmetrically installed at the bottom of the water guide channel 2202, and the mounting legs 2203 support the drainage channel 21.

[0035] Both the main sewer 14 and the auxiliary sewer 16 are equipped with gates 23 on their left and right sides. Each gate 23 includes a frame 2301. A baffle 2302 is installed on the upper part of the frame 2301. The baffle 2302 has a hollow structure inside and a sliding door 2304 is installed thereon. A rack 2305 is installed on the back of the sliding door 2304. A rotating shaft 2303 is installed between the frames 2301 inside the baffle 2302. A gear that meshes with the rack 2305 is fixedly connected to the rotating shaft 2303. One end of the rotating shaft 2303 is rotatably mounted on the frame 2301, and the other end extends out of the frame 2301 and is connected to a forward and reverse stepper motor.

[0036] Specifically, by starting the forward and reverse stepper motor, the rotating shaft 2303 rotates, which drives the gear to rotate. The rack 2305 that meshes with the gear drives the gate 2304 to move up and down, thus realizing the opening and closing operation of the gate.

[0037] In addition, photovoltaic panels are installed on the roof of cattle shed 1. These panels effectively block direct sunlight, reducing heat absorption in summer and lowering the temperature inside the shed. The photovoltaic power generation is directly connected to the cattle shed's power grid to meet daily electricity needs: basic electricity for lighting, fan ventilation and cooling systems, etc.; and specialized electricity for manure treatment equipment, high-pressure flushing devices, and disinfection spraying equipment, etc. If there is excess power generation, it can also be fed into the grid. In short, the installation of photovoltaic panels on the roof of cattle shed 1 is an innovative model integrating "livestock farming + clean energy." It not only improves the cattle shed environment by providing shading for the panels but also meets internal electricity needs through power generation, achieving a dual improvement in ecological and economic benefits.

[0038] The operation process of this invention is as follows: When cleaning the cattle shed, after most of the manure, feed, and debris have been removed, some manure and other substances that are difficult to clean remain on the ground of cattle shed 1. At this time, they are flushed into the drainage channel 21 by high pressure water pipes, and then converge into the main drainage channel 14 and the auxiliary drainage channel 16. Then, the gate 23 on the side of the main drainage channel 14 connecting to the stacking pipe 20, as well as the gate 23 on the side of the short pipe 18 of the left auxiliary drainage channel 16 and the long pipe 17 of the right auxiliary drainage channel 16, are opened. The water carries the manure and other organic matter into the stacking pipe 20, and finally into the biogas power station 11 for fermentation. Finally, after the biogas is purified, it is mixed with air in a certain proportion and enters the engine cylinder. The fuel is ignited by the spark plug (internal combustion engine) or driven by high-temperature gas (gas turbine), and the generated high-temperature and high-pressure gas drives the piston (or turbine) to rotate, which drives the generator rotor to rotate, cutting magnetic field lines to generate electricity. Part of the electricity is used for the needs of cattle shed 1, and the remainder is fed into the power grid.
