[0023] Example 1, please refer to Figure 1-7 The present invention provides an embodiment of a closed-loop livestock and poultry house air environment control device, comprising a detection mechanism 15 for detecting the livestock house environment, a base 1, a water tank 2, and an outer shell 4 installed on the top of the base 1. Specifically, the detection mechanism 15 includes a temperature sensor 1501, a humidity sensor 1502, and a harmful gas detection sensor 1503, which are used to detect the temperature, humidity, and gas concentrations of CO2, H2S, or NH3 in the livestock and poultry house, respectively. Multiple detection mechanisms 15 are provided, which are independent and can be placed in various parts of the livestock house for more accurate detection. In this embodiment, a detection mechanism 15 is also installed on the top of the outer shell 4.

[0024] In this embodiment, the outer shell 4, water tank 2, and base 1 are all rectangular parallelepiped structures. The dimensions of the base 1 and the outer shell 4 are smaller than the dimensions of the water tank 2. A water inlet is provided at the top of one side of the water tank 2. For easy cleaning, an openable drain outlet is provided at the bottom of the water tank 2. The base 1 is vertically movable inside the water tank 2, and a fixing mechanism 16 for fixed connection with the water tank 2 is provided at the edge of the top of the base 1. The fixing mechanism 16 includes four vertically fixed threaded rods 1601 at the four corners of the top of the base 1 and fastening nuts 1602 threadedly connected to the threaded rods 1601. The top of the water tank 2... A through hole adapted to the outer shell 4 is provided in the middle, which facilitates the sliding of the base 1 and the outer shell 4 inside the water tank 2. A through hole adapted to the threaded rod 1601 is provided at the top edge of the water tank 2. When not in use or during transportation, the base 1 can be slid to the bottom of the water tank 2 to reduce the volume occupied by the equipment. When in use, the outer shell 4 is raised above the water tank 2, and the threaded rod 1601 passes through the through hole at the top edge of the 2 and is threaded to the fastening nut 1602 to fix the base 1 and the water tank 2. The large-capacity water tank 2 can reduce the inconvenience of frequent water filling during use and is more convenient to use.

[0025] Furthermore, four casters 17 are installed at the bottom of the water tank 2 to facilitate moving and adjusting the position of the equipment.

[0026] The outer shell 4 has several through holes on its side wall. The inner side of the outer shell 4 has a supporting cavity 3. The top of the supporting cavity 3 abuts against the top of the inner side of the outer shell 4. The supporting cavity 3 divides the side walls of the outer shell 4 into two independent first chambers 5 and second chambers 6. In this embodiment, the first chamber 5 is located on the front side of the outer shell 4, and the second chamber 6 is located on the left, right and rear sides of the outer shell 4. Further, the first chamber 5 and the second chamber 6 can also be set as an L-shaped structure connected end to end as needed.

[0027] An electric heating tube 7 is installed inside the first chamber 5. An evaporative heat-absorbing layer 8, specifically made of kraft paper, is installed inside the second chamber 6. A first water pipe 11 is installed at the top of the second chamber 6. A water pump 12 for pumping water from the water tank 2 into the first water pipe 11 is installed at the top of the base 1. Specifically, one end of the water pump 12 is connected to the inside of the water tank 2 through a metal flexible hose, and the output end of the water pump 12 is connected to the inside of the first water pipe 11 through a second water pipe 13. The first water pipe 11 is located directly above the evaporative heat-absorbing layer 8, and several water injection holes 1101 are provided at the bottom of the first water pipe 11. The water pump 12 draws water from the water tank 2 into the first water pipe 11, and then injects it into the evaporative heat absorption layer 8 through the water injection hole 1101. During operation, air flows from the gaps in the evaporative heat absorption layer 8 to accelerate the evaporation of water, thereby absorbing heat and cooling down. Furthermore, the output end of the second water pipe 13 is provided with a branch pipe 1301, and the branch pipe 1301 is equipped with an ultrasonic atomizing nozzle 14. Valves 1302 are installed on both the output end of the second water pipe 13 and the branch pipe 1301, which can draw water into the first water pipe 11 or the ultrasonic atomizing nozzle 14, or both, as needed.

[0028] Reference Appendix Figure 2-3The outer casing 4 includes a first side plate 401 fixed to one side of the top of the base 1, a top plate 403 fixed to the top of the first side plate 401, and a second side plate 402 detachably installed on the outside of the evaporative heat absorption layer 8. The first side plate 401 and the second side plate 402 are connected end to end. The second side plate 402 is specifically a C-shaped structure, including vertical plates set vertically on the left, right and rear sides of the top of the base 1. Several hollow positioning columns 302 are fixed on the supporting inner cavity 3 on the inner wall of the second chamber 6. Through holes adapted to the positioning columns 302 are provided through the evaporative heat absorption layer 8. Mounting holes 404 adapted to the positioning columns 302 are provided through the second side plate 402. The mounting holes 404 and the positioning columns 302 are fixedly connected by bolts. The positioning columns 302 can support and position the evaporative heat absorption layer 8, and at the same time facilitate the disassembly and assembly of the second side plate 402. After working for a period of time, the second side plate 402 can be removed to replace or clean the evaporative heat absorption layer 8, which is convenient, quick and safe.

[0029] An exhaust fan 10 is installed at the top of the outer shell 4. Several ventilation holes are provided at the top of the outer shell 4 to draw air from the livestock shed into the supporting inner cavity 3. Several first ventilation holes 301, respectively communicating with the interior of the first chamber 5 and the second chamber 6, are provided through the side wall of the supporting inner cavity 3. An adjustment mechanism 9 is provided on the inner side wall of the supporting inner cavity 3 to control the alternating opening and closing of the first ventilation holes 301 communicating with the interior of the first chamber 5 and the second chamber 6. Referring to references 5-6, the adjustment mechanism 9 includes first baffles 90 that abut against the inner side wall of the supporting inner cavity 3. The first baffle 901 and the second baffle 902 are slidably connected to the inner wall of the supporting cavity 3 via a slide rail. The first baffle 901 is located on the side wall near the first chamber 5, and the second baffle 902 is located on the side wall near the second chamber 6. The first baffle 901 and the second baffle 902 are respectively provided with a second ventilation hole 9011 and a third ventilation hole 9021 that are adapted to the first ventilation hole 301. Specifically, the first ventilation hole 301, the second ventilation hole 9011 and the third ventilation hole 9021 are the same size and are all strip-shaped through holes arranged at equal intervals from top to bottom. The distance between two adjacent adjustment holes is greater than the width of the hole. A gear 905 is mounted on one side of the top of the base 1 via a motor 906. A first rack 903 and a second rack 904 are respectively slidably arranged on both radial sides of the gear 905. The first rack 903 is fixedly connected to the first baffle 901, and the second rack 904 is fixedly connected to the second baffle 902. The first rack 903 and the second rack 904 drive the first baffle 901 and the second baffle 902 to move up and down, causing the second ventilation hole 9011 and the third ventilation hole 9021 to move in relation to the first ventilation hole 903. 01. Overlapping or separating: Specifically, the motor 906 is mounted on the top of the base 1 via a support plate, and its output end is fixedly mounted with the gear 905. During operation, the motor 906 drives the gear 905 to rotate, and the gear 905 meshes with the first rack 903 and the second rack 904, causing the first rack 903 and the second rack 904 to move in opposite directions, which in turn causes the first baffle 901 and the second baffle 902 to move in opposite directions. This can adjust the opening and closing of the ventilation holes, allowing the air entering the outer casing 4 to be discharged after heating or after evaporation and heat absorption as needed.

[0030] Furthermore, a closed-loop livestock and poultry house air environment control device also includes several exhaust fans installed on the walls of the livestock house, which can accelerate the air exchange between the livestock and poultry house and the outside.

[0031] Furthermore, a closed-type livestock and poultry house air environment control device also includes a controller. The output terminals of the temperature sensor 1501, humidity sensor 1502, and harmful gas detection sensor 1503 are electrically connected to the input terminal of the controller. The output terminal of the controller is electrically connected to the input terminals of the exhaust fan 10, exhaust fan, electric heating tube 7, water pump 12, and motor 906, which can intelligently control the operation of each electrical component.

[0032] Working principle: During operation, the temperature sensor 1501 detects the temperature inside the livestock and poultry house, the humidity sensor 1502 detects the humidity inside, and the harmful gas detection sensor 1503 detects the concentration of CO2, H2S or NH3.

[0033] When the temperature sensor 1501 detects a low temperature, it turns on the electric heating element 7 and the exhaust fan 10. The exhaust fan 10 draws cold air from the outside into the housing 4, driving the gear 905 to rotate via the motor 906. This, in turn, causes the first rack 903 and the first baffle 901 to slide downwards, aligning the second ventilation hole 9011 with the first ventilation hole 301 on the side wall of the first chamber 5. At this time, the third ventilation hole 9021 separates from the first ventilation hole 301 on the side wall of the second chamber 6, allowing air entering the housing 4 to be blown towards the electric heating element 7 only through the second ventilation hole 9011. The electric heating element 7 heats the cold air and then blows it out through the through-holes in the housing 4. When the indoor temperature is high, the motor 906... 06 drives gear 905 to rotate in the opposite direction. At this time, the second rack 904 and the second baffle 902 descend, while the first baffle 901 and the first rack 903 rise, causing the third ventilation hole 9021 to coincide with the first ventilation hole 301 on the side wall of the second chamber 6, and the second ventilation hole 9011 to separate from the first ventilation hole 301 on the side wall of the first chamber 5. The water pump 12 draws water from the water tank 2 into the first water pipe 11, and then injects it into the evaporative heat absorption layer 8 through the water injection hole 1101. The exhaust fan 10 draws outside air into the outer shell 4, supporting the high pressure formed inside the inner cavity 3 and the outer shell 4. The air can only pass through the evaporative heat absorption layer 8 and then be cooled and discharged as cold air, thus cooling the livestock house and ensuring that the livestock and poultry are in a suitable temperature environment.

[0034] When the humidity sensor 1502 detects that the humidity in the livestock house exceeds the preset safety threshold, the system will automatically start the exhaust fan on the livestock house wall to expel the humid air inside the livestock house and maintain a suitable humidity environment. When the indoor humidity is low, the valve 1302 can be opened and the water pump 12 can draw water from the water tank 2 into the ultrasonic atomizing nozzle 14 and spray it out after atomization to increase the humidity in the livestock house to a suitable level.

[0035] When the hazardous gas detection sensor 1503 detects that the concentration of any of the gases, CO2, H2S, or NH3, exceeds the preset safety threshold, the exhaust fan will start. The exhaust fan will then quickly expel the hazardous gases outdoors, allowing outdoor air to enter the livestock shed through doors and windows, effectively accelerating air exchange and rapidly improving the air quality inside the livestock shed.

[0036] Example 2: Based on Example 1, this example has a through hole provided on the base 1 below the evaporative heat absorption layer 8, which communicates with the inside of the water tank 2. Excess water that wets the evaporative heat absorption layer 8 will flow back into the water tank 2 through the through hole for further recycling, making it more energy-efficient and environmentally friendly.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
