Description

Technical Field

[0001] The present invention relates to the technical field of anti-condensation water in pipelines, and specifically to a device and method for preventing condensation water in precise air supply pipelines in livestock houses. Background Art

[0002] In order to ensure good air quality in the barn, air supply ducts are installed in the barn to provide a suitable ambient temperature and effectively remove excess heat and harmful gases. Taking the pig house as an example, the air quality in the pig house directly affects the health and growth of the pigs. By installing air supply ducts, fresh air can be introduced and dirty air containing harmful gases such as ammonia and carbon dioxide can be exhausted, thus creating a clean breathing environment.

[0003] However, in the cold winter, when the air flow temperature inside the ventilation duct is low and the temperature inside the pig house is high and the humidity is high, condensation water is easily formed on the wall below the bottom wall of the ventilation duct, and water droplets are easy to drip onto the pigs' body surface or the ground, which is prone to the following problems:

[0004] 1. Condensate may contain various bacteria and viruses; these microorganisms multiply under favorable conditions and may cause infection when condensate drips onto pigs.

[0005] 2. Causes stress response: Condensation water is usually cold, and when it suddenly drips onto the pig, especially the back or head, it may cause a stress response in the pig.

[0006] 3. Affecting the comfort and health of pigs: Continuous dripping of condensed water will reduce the quality of life of pigs and make them feel uncomfortable. This will not only affect the growth rate of pigs, but may also lead to a decrease in their immune ability and increase the risk of illness. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a device and method for preventing condensation water in precise air supply ducts of livestock houses. By installing side air outlet ducts that can be flipped up and down on the side walls of each air outlet channel, in winter, the side air outlet ducts are flipped to a horizontal or inclined upward state. At this time, the temperature difference between the top and bottom of the bottom wall of the air outlet channel is small, so no condensation droplets will form below the bottom wall of the air outlet channel, which can effectively prevent condensation water from dripping onto livestock, thereby preventing bacteria and viruses in the condensation water from multiplying on the livestock, and will not cause stress reactions in livestock, thereby ensuring the healthy growth of livestock.

[0008] The technical solution of the present invention is achieved in this way:

[0009] A device for preventing condensation water from accurately supplying air to a livestock house comprises an air supplying ...

[0010] A plurality of side avoidance openings distributed in a circumferential array are provided on the side wall of the air outlet channel, a side air outlet pipe is rotatably installed in each side avoidance opening, and an air outlet cover is installed at the lower air outlet of the air outlet channel;

[0011] The side air outlet duct can be turned upside down.

[0012] By adopting the above scheme, the present invention installs side air outlet ducts that can be flipped up and down on the side walls of each air outlet channel. In winter, the side air outlet ducts are flipped to a horizontal or inclined upward state. At this time, the temperature difference between the top and bottom of the bottom wall of the air outlet channel is small, so condensation droplets will not form below the bottom wall of the air outlet channel, which can effectively prevent condensation water from dripping onto livestock, thereby preventing bacteria and viruses in the condensation water from multiplying on the livestock, and will not cause stress reactions in livestock, thereby ensuring the healthy growth of livestock.

[0013] As a preferred embodiment of a device for preventing condensation water in precise air supply ducts of a livestock house, an air guide port is opened in the portion of the side air outlet duct located in the air outlet channel, and the opening direction of the air guide port faces upward.

[0014] With the above solution, in order to facilitate the air flow into the side air outlet duct, an air guide port is opened on the side air outlet duct, thereby expanding its air inlet and facilitating the air flow into the side air outlet duct.

[0015] As a preferred embodiment of a device for preventing condensation water in precise air supply ducts of a livestock house, a synchronous flip adjustment component for controlling the simultaneous flipping of all side air outlet ducts is installed inside the air outlet duct;

[0016] The synchronous flip adjustment assembly includes a center frame;

[0017] The periphery of the center frame is connected to the side air outlet ducts in sequence through an adjustable skeleton mechanism;

[0018] An adjusting screw is threadedly mounted at the center of the air outlet cover, and the top of the adjusting screw extends into the air outlet channel and always contacts the bottom of the center frame;

[0019] The height of the center frame can be adjusted by turning the adjustment screw up and down, thereby synchronously controlling the flipping status of all side air outlet ducts.

[0020] Wherein, the adjustable frame mechanism comprises a main frame, which is rotatably mounted on the side of the center frame;

[0021] A telescopic frame is slidably installed in the main frame, and a clamp is connected to the end of the telescopic frame away from the main frame. The clamp is clamped on the side air outlet pipe; the assembly relationship between the clamp and the side air outlet pipe is interference fit.

[0022] By adopting the above scheme, in order to facilitate the synchronous control of the flipping of all side air outlet ducts, a synchronous flip adjustment component is added, and the adjusting screw is rotated to move the adjusting screw downward. At this time, the center frame moves downward synchronously with the adjusting screw under the action of gravity; while the center frame moves downward, all the side air outlet ducts are driven to flip through the adjustable skeleton mechanism.

[0023] As a preferred implementation of a device for preventing condensation water in precise air supply ducts of a livestock house, the top end of the adjusting screw is a smooth round head.

[0024] By adopting the above scheme, in order to reduce the friction between the top end of the adjusting screw and the center frame when it rotates, the top end is set to be a round head, and the contact area between it and the center frame is smaller, which will save more effort when rotating the adjusting screw.

[0025] A method for preventing condensation water in a precise air supply duct of a livestock house, the method is implemented by using the device for preventing condensation water in a precise air supply duct of a livestock house, and the specific operation steps are as follows:

[0026] S1. In winter, the adjusting screw is rotated to move downward, and the center frame moves downward synchronously with the adjusting screw under the action of gravity;

[0027] S2. While the center frame moves downward, the adjustable frame mechanism drives all the side air outlet ducts to flip upward, and finally all the side air outlet ducts are flipped to a horizontal or inclined upward state;

[0028] S3. Since the air supply duct will deliver cold air to the barn in winter, the cold air will be delivered to the barn normally through the air outlet hood, thereby promoting air circulation;

[0029] S4. At the same time, cold air will be transported to all directions below the bottom wall of the air supply duct through the side air outlet pipe, and then a cold air layer will be formed just below the bottom wall of the air outlet channel. At this time, the temperature difference between the top and bottom of the bottom wall of the air outlet channel is small, so no condensation droplets will form below the bottom wall of the air outlet channel.

[0030] After adopting the above technical solution, the beneficial effects of the present invention are:

[0031] 1. By installing a side air outlet duct that can be turned upside down on the side wall of each air outlet channel, in winter, the side air outlet duct is turned to a horizontal or inclined upward state. At this time, the temperature difference between the upper and lower parts of the bottom wall of the air outlet channel is small, so no condensation droplets will form below the bottom wall of the air outlet channel, which can effectively prevent condensation water from dripping onto livestock, thereby preventing bacteria and viruses in the condensation water from multiplying on livestock, and will not cause stress reactions in livestock, ensuring the healthy growth of livestock;

[0032] 2. In order to facilitate the air flow into the side air outlet duct, an air guide port is opened on the side air outlet duct, thereby expanding its air inlet and facilitating the air flow into the side air outlet duct;

[0033] 3. In order to facilitate the synchronous control of the flipping of all side air outlet ducts, a synchronous flipping adjustment component is added. The adjusting screw is turned and moved downward. At this time, the center frame moves downward synchronously with the adjusting screw under the action of gravity; while the center frame moves downward, it drives all side air outlet ducts to flip through the adjustable skeleton mechanism;

[0034] 4. In order to reduce the friction between the top of the adjusting screw and the center frame when it rotates, the top of the adjusting screw is set to a round head. The contact area between the top and the center frame is smaller, which will save more effort when turning the adjusting screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1, as Figures 1 to 8 As shown, a device for preventing condensation water from a precise air supply duct 1 of a pig house is applied in a pig house, comprising an air supply duct 1 installed above the pig house, and a plurality of evenly distributed and downwardly opened air outlet channels 2 are installed on the bottom wall of the air supply duct 1; a plurality of side avoidance openings 3 distributed in a circumferential array are opened on the side wall of the air outlet channel 2, and a side air outlet duct 4 is rotatably installed in each side avoidance opening 3, and an air outlet cover 5 is installed at the lower air outlet of the air outlet channel 2 by screws; the side air outlet duct 4 can be turned up and down. The present invention installs a side air outlet duct 4 that can be turned up and down on the side wall of each air outlet channel 2, and in winter, the side air outlet duct 4 is turned over to a horizontal or inclined upward state, at which time the temperature difference between the top and bottom of the bottom wall of the air outlet channel 2 is small, so no condensation water droplets will be formed below the bottom wall of the air outlet channel 2, which can effectively prevent condensation water from dripping onto the pigs, thereby preventing bacteria and viruses in the condensation water from breeding on the pigs, and will not cause stress reactions in the pigs, thereby ensuring the healthy growth of the pigs.

[0049] like Figure 6 As shown, an air guide port 6 is provided in the portion of the side air outlet duct 4 located in the air outlet channel 2, and the opening direction of the air guide port 6 faces upward. In order to facilitate the air flow into the side air outlet duct 4, the air guide port 6 is provided on the side air outlet duct 4, thereby expanding its air inlet and facilitating the air flow into the side air outlet duct 4.

[0050] like Figure 6 to Figure 7As shown, the interior of the air outlet channel 2 is equipped with a synchronous flip adjustment component that controls the simultaneous flipping of all the side air outlet ducts 4; the synchronous flip adjustment component includes a center frame 7; the periphery of the center frame 7 is connected to the side air outlet ducts 4 in sequence through an adjustable skeleton mechanism; the center of the air outlet cover 5 is threadedly equipped with an adjustment screw 8, the top of which extends into the interior of the air outlet channel 2 and always contacts the bottom of the center frame 7; the height of the center frame 7 can be adjusted by rotating the adjustment screw 8 up and down, thereby synchronously controlling the flipping state of all the side air outlet ducts 4. Among them, the adjustable skeleton mechanism includes a main skeleton 9, which is rotatably installed on the side of the center frame 7; a telescopic skeleton 10 is slidably installed in the main skeleton 9, and a clamp 11 is connected to the end of the telescopic skeleton 10 away from the main skeleton 9, and the clamp 11 is clamped on the side air outlet duct 4; the assembly relationship between the clamp 11 and the side air outlet duct 4 is an interference fit. In order to facilitate the synchronous control of the flipping of all the side air outlet ducts 4, a synchronous flip adjustment component is added, and the adjusting screw 8 is rotated to move the adjusting screw 8 downward. At this time, the center frame 7 moves downward synchronously with the adjusting screw 8 under the action of gravity; while the center frame 7 moves downward, it drives all the side air outlet ducts 4 to flip through the adjustable skeleton mechanism.

[0051] like Figure 6 As shown, the top of the adjusting screw 8 is a smooth round head. In order to reduce the friction between the top of the adjusting screw 8 and the center frame 7 when the adjusting screw 8 is rotated, the top of the adjusting screw 8 is set to a round head, and the contact area between the top of the adjusting screw 8 and the center frame 7 is small, which will save more effort when rotating the adjusting screw 8.

[0052] like Figures 1 to 8 As shown, a method for preventing condensation water from the precise air supply duct 1 of a pig house is implemented by using a device for preventing condensation water from the precise air supply duct 1 of the pig house, and the specific operation steps are as follows:

[0053] S1. In winter, the adjusting screw 8 is rotated to move downward, and the center frame 7 moves downward synchronously with the adjusting screw 8 under the action of gravity;

[0054] S2, while the center frame 7 moves downward, the adjustable frame mechanism drives all the side air outlet ducts 4 to flip upward, and finally all the side air outlet ducts 4 are flipped to a horizontal or inclined upward state;

[0055] S3. Since the air supply duct 1 will deliver cold air to the pig house in winter, the cold air will be delivered to the pig house normally through the air outlet hood 5, thereby promoting air circulation;

[0056] S4. At the same time, cold air will be transported to all directions below the bottom wall of the air supply duct 1 through the side air outlet pipe 4, and then a cold air layer will be formed just below the bottom wall of the air outlet channel 2. At this time, the temperature difference between the top and bottom of the bottom wall of the air outlet channel 2 is small, so no condensation droplets will form below the bottom wall of the air outlet channel 2.

[0057] Embodiment 2, as Figures 9 and 10 As shown, the difference between this embodiment and the first embodiment is that this embodiment is applied to non-winter (i.e., spring, summer or autumn), when the outside temperature is relatively high; the adjusting screw 8 is rotated to move the adjusting screw 8 upward, and the center frame 7 moves upward synchronously with the adjusting screw 8 under the action of gravity; while the center frame 7 moves upward, it drives all the side air outlet ducts 4 to flip downward through the adjustable skeleton mechanism, and finally all the side air outlet ducts 4 are flipped to a tilted downward state, at which time natural wind can be blown out through the side air outlet ducts 4 in all directions, which can provide air fluidity and create a clean breathing environment for the pig house.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
