Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, specifically relating to equipment used in animal housing, and particularly to an intelligent IoT-based permanent magnet fan for ranching and its working method. Background Technology

[0002] With the continuous advancement of technology and the development of animal husbandry, a large number of livestock are kept in livestock sheds. Due to the large number of livestock, the air circulation in the livestock sheds is very poor. Over time, this will affect the livestock's breathing and cause some diseases.

[0003] In related technologies, multiple fans are often installed on livestock sheds to ensure air circulation inside. At the same time, in order to maintain the air humidity inside the livestock shed, water pipes are installed at the air outlets of the fans. When the fans are working, the water pipes spray water mist outward to ensure the humidity and smooth airflow inside the shed.

[0004] Because livestock sheds are mostly built in remote areas far from urban suburbs, access to tap water is inconvenient. Therefore, water supply relies on a combination of rainwater and groundwater collection. To prevent nozzle clogging, a filter screen is usually installed at the connection between the water pipe and the nozzle to filter out large particles of impurities in the water. Since the selected water bodies contain a high amount of impurities, the filter screen frequently becomes clogged. If it cannot be replaced manually in a timely manner, the humidity inside the shed will not reach the set level, affecting livestock growth.

[0005] Therefore, how to solve the problem of the filter screen between the nozzle and the water pipe, which can easily affect the smooth spraying of water outwards if it is not replaced in time, is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0008] In a first aspect, embodiments of this disclosure provide an intelligent IoT-enabled permanent magnet fan for ranching, comprising:

[0037] The adjusting component is slidably positioned near the blower body of the spray device;

[0038] The spraying device includes a filter screen;

[0039] During assembly, the adjusting component pushes the filter screen into the spray device until it is stopped at the inner end of the filter screen against the inner wall of the spray device.

[0040] If the air force at the air outlet of the blower increases, the adjusting component is pushed into the spray device and slides. The adjusting component is suitable for scraping off impurities from the inner wall of the filter screen.

[0041] When the regulating component moves inward to block the outlet of the water pipe, the regulating component is deformed by the water flow, and the regulating component is adapted to vibrate the filter screen to shake off the impurities on the filter screen.

[0042] In one optional embodiment, the spraying device includes: a positioning block disposed on the side wall of the louver, and one end of the water pipe passing through the positioning block;

[0043] A limiting cylinder is provided on the side wall of the positioning block and extends along the air outlet direction of the fan body. The limiting cylinder is connected to the water pipe.

[0046] The adjustment component is slidably disposed inside the limiting cylinder, and the adjustment component is linked with the filter screen;

[0047] The water flow delivered from the water pipe to the limiting cylinder is filtered by the filter screen and then sprayed outward in a mist form through the spray head.

[0048] The louvers rotate relative to the fan body, increasing the thrust of the wind on the adjusting component. The adjusting component slides into the limiting cylinder to scrape away impurities from the inner wall of the filter screen.

[0049] In one optional embodiment, the adjusting assembly includes: an adjusting cylinder that slides and seals with the limiting cylinder;

[0050] The outer wall of the regulating cylinder is provided with several grooves along the axial direction that are adapted to the filter screen.

[0051] When the regulating cylinder slides into the limiting cylinder, the outer wall of the regulating cylinder is adapted to block the water outlet;

[0052] When the adjusting cylinder moves relative to the filter screen, the inner wall of the adjusting cylinder rubs against the outer wall of the filter screen to scrape away impurities on the filter screen.

[0053] In one optional embodiment, the outer wall of the regulating cylinder is provided with a plurality of regulating ports, each regulating port corresponding to a filter screen, and the inner diameter of the regulating port is larger than the inner diameter of the water outlet.

[0054] Each of the adjustment ports is provided with an adjustment membrane, and a gap is provided between the inner wall of the adjustment membrane and the outer wall of the filter screen.

[0055] The regulating cylinder slides into the limiting cylinder until the regulating membrane seals the water outlet;

[0056] The water flow pushes the regulating membrane inward, causing it to impact the outer wall of the filter screen and shake off impurities.

[0057] Thirdly, this disclosure also provides a method for operating a permanent magnet fan, the method comprising:

[0058] The louvers rotate relative to the fan body to adjust the airflow direction and flow rate of the air blown into the breeding shed by the fan body;

[0059] Water pipes deliver water to a spraying device, which is adapted to spray water in a mist form into the breeding shed to regulate the humidity of the air inside the breeding shed;

[0060] When the adjusting component is pushed to move away from the fan body, the adjusting component moves relative to the filter screen to scrape off impurities from the inner wall of the filter screen;

[0061] When the adjusting component moves to the outlet of the blocked water pipe, the water flow pushes the adjusting component to deform, and the adjusting component is adapted to vibrate the filter screen to shake off the impurities on the filter screen.

[0062] The beneficial effects of this invention are that the intelligent IoT-based permanent magnet fan for livestock farming and its working method achieve automatic filter cleaning through the cooperation of louvers, a spray device, and an adjusting component. When the adjusting component is pushed away from the fan body, it can scrape off impurities from the inner wall of the filter, thus achieving automatic filter cleaning. When the adjusting component moves to the outlet of the blocked water pipe, its deformation can vibrate the filter to shake off impurities, avoiding frequent filter replacements and ensuring that the humidity in the livestock shed remains within a reasonable range.

[0083] Research has revealed the following drawbacks of existing technologies: In related technologies, multiple fans are often installed on the livestock shed to ensure air circulation inside; at the same time, in order to maintain the air humidity inside the livestock shed, water pipes are installed at the air outlets of the fans, and water mist is sprayed outwards from the water pipes when the fans are working to ensure the humidity and smooth airflow inside the shed.

[0084] Because livestock sheds are mostly built in remote areas far from urban suburbs, access to tap water is inconvenient. Therefore, water supply relies on a combination of rainwater and groundwater collection. To prevent nozzle clogging, a filter screen is usually installed at the connection between the water pipe and the nozzle to filter out large particles of impurities in the water. Since the selected water bodies contain a high amount of impurities, the filter screen frequently becomes clogged. If it cannot be replaced manually in a timely manner, the humidity inside the shed will not reach the set level, affecting livestock growth.

[0085] Therefore, how to solve the problem of the filter screen between the nozzle and the water pipe, which affects the smooth spraying of water outwards if not replaced in time, is a technical problem that urgently needs to be solved in this field.

[0086] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0087] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0088] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0089] like Figures 1 to 7 As shown, at least one embodiment provides an intelligent IoT-enabled permanent magnet fan for ranching, comprising: a fan body 1; the fan body 1 includes a permanent magnet motor drive, which is adapted to drive the fan of the fan body 1 at different rotation speeds depending on the season. A plurality of louvers 2 are hinged at equal intervals to the air outlet sidewall of the fan body 1; the rotation angle of the louvers 2 is 0-180°.

[0090] Reference Appendix Figure 4 When the louver 2 is rotated to an angle of 5-15° with the horizontal plane, preferably 10°, 12° or 165-175°, preferably 170° or 173°; at this time, the airflow from the fan body 1 flows through the louver 2 to the livestock shed at a relatively low speed. At this time, the adjusting component 4 is at the end of the limiting cylinder 32 closest to the fan body 1.

[0091] Continue to refer to the appendix Figure 4When the louvers 2 are rotated to 90° with the horizontal plane, the airflow from the blower body 1 flows through the louvers 2 to the livestock shed at a relatively high speed. The regulating component 4 is pushed to move towards the spray head 33, and the regulating cylinder 41 moves relative to the filter screen 34. The inner wall of the regulating cylinder 41 abuts against the outer wall of the filter screen 34 to scrape off the impurities on the filter screen 34.

[0092] Reference Appendix Figure 2 A spray device 3 is installed on the outer wall of the louver 2 and connected to the water pipe 5. An adjusting component 4 is slidably installed inside the spray device 3 and is linked to the filter screen 34 of the spray device 3. When the adjusting component 4 is pushed away from the fan body 1, it moves relative to the filter screen 34 to scrape off impurities from the inner wall of the filter screen 34. When the adjusting component 4 moves to block the outlet 50 of the water pipe 5, the water flow pushes the adjusting component 4 to deform, and the adjusting component 4 is adapted to vibrate the filter screen 34 to shake off impurities. Through the cooperation of the louver 2, the spray device 3, and the adjusting component 4, the effect of automatically cleaning the filter screen 34 is achieved. When the adjusting component 4 is pushed away from the fan body 1, it can scrape off impurities from the inner wall of the filter screen 34, thus achieving automatic cleaning of the filter screen 34. When the adjusting component 4 moves to the outlet 50 of the blocked water pipe 5, the deformation of the adjusting component 4 can vibrate the filter screen 34 to shake off the impurities on the filter screen 34, avoiding frequent replacement of the filter screen 34 and ensuring that the humidity in the livestock shed is within a reasonable range.

[0093] Reference Appendix Figure 3 The spray device 3 includes: a positioning block 31, which is disposed on the side wall of the louver 2, and one end of the water pipe 5 passes through the positioning block 31; the positioning block 31 and the water pipe 5 are in a sliding seal, that is, when the louver 2 drives the positioning block 31 to rotate, the positioning block 31 is adapted to move relative to the water pipe 5. Furthermore, the water pipe 5 is flexible so that when the louver 2 drives the positioning block 31 to rotate, the water pipe 5 still maintains a state of communication with the limiting cylinder 32. The limiting cylinder 32 is disposed on the side wall of the positioning block 31 and extends along the air outlet direction of the fan body 1. The limiting cylinder 32 is connected to the water pipe 5; the limiting cylinder 32 is hollow inside. A spray head 33 is disposed inside the limiting cylinder 32 at one end away from the fan body 1; the filter screen 34 is detachably disposed on the inner wall of the limiting cylinder 32.

[0094] The adjusting component 4 is slidably disposed within the limiting cylinder 32, and the adjusting component 4 and the limiting cylinder 32 are slidably sealed; and the adjusting component 4 is linked with the filter screen 34; after the water flows into the limiting cylinder 32 through the positioning block 31, the filter screen 34 is adapted to filter impurities in the water flow. At this time, the adjusting component 4 is adapted to seal the end of the limiting cylinder 32 to prevent the water flow from flowing towards the fan body 1; at this time, the filtered water flow flows towards the spray head 33, and the spray head 33 is adapted to spray the water flow in a mist out of the limiting cylinder 32. Among them, the water flow delivered by the water pipe 5 to the limiting cylinder 32 is filtered by the filter screen 34 and then sprayed outward in a mist form through the spray head 33; the louvers 2 rotate relative to the fan body 1, the adjusting component 4 is subjected to increased wind thrust, and the adjusting component 4 slides into the limiting cylinder 32 to scrape off impurities on the inner wall of the filter screen 34.

[0095] Continue to refer to the appendix Figure 3 The adjusting component 4 includes an adjusting cylinder 41, which is slidably sealed to a limiting cylinder 32. The adjusting cylinder 41 is hollow inside, and when the wind thrust on the adjusting cylinder 41 increases, the adjusting cylinder 41 is adapted to move into the limiting cylinder 32. The outer wall of the adjusting cylinder 41 has several grooves 42 along the axial direction that are adapted to the filter screen 34. When the adjusting cylinder 41 slides into the limiting cylinder 32, the filter screen 34 is adapted to be inserted into the grooves 42 of the adjusting cylinder 41, and the inner wall of the grooves 42 is in contact with the outer wall of the filter screen 34 to scrape away impurities in the mesh of the filter screen 34. The cleaned impurities are adapted to fall into the interior of the adjusting cylinder 41. When the adjusting cylinder 41 slides into the limiting cylinder 32, the outer wall of the adjusting cylinder 41 is adapted to block the water outlet 50. When the adjusting cylinder 41 moves relative to the filter screen 34, the inner wall of the adjusting cylinder 41 rubs against the outer wall of the filter screen 34 to scrape away impurities on the filter screen 34.

[0096] Reference Appendix Figure 6 The regulating cylinder 41 has several regulating ports on its outer wall, each port corresponding to a filter screen 34. The inner diameter of each regulating port is larger than the inner diameter of the outlet 50. Each regulating port contains a regulating membrane 43, which is elastic. The outer wall of the regulating membrane 43 is coplanar with the outer wall of the regulating cylinder 41, and the thickness of the regulating membrane 43 is less than the wall thickness of the regulating cylinder 41. When the regulating cylinder 41 slides relative to the filter screen 34, there is a gap between the inner wall of the regulating membrane 43 and the outer wall of the filter screen 34. When the regulating cylinder 41 slides relative to the filter screen 34, the side wall of the sliding groove 42 rubs against the outer wall of the filter screen 34 to scrape away impurities on the mesh of the filter screen 34. At this time, the impurities on the filter screen 34 will not come into contact with the regulating membrane 43. As the thrust of the wind received by the regulating cylinder 41 continues to increase, the regulating cylinder 41 slides into the limiting cylinder 32 until the regulating membrane 43 blocks the water outlet 50. At this time, the water flow in the water pipe 5 will not continue to flow into the limiting cylinder 32. The water flow pushes the regulating membrane 43 inward and deforms it. The regulating membrane 43 hits the outer wall of the filter screen 34 to shake off the impurities on the filter screen 34.

[0097] Reference Appendix Figure 5 The filter screen 34 is arc-shaped, and its outer wall fits against the inner wall of the limiting cylinder 32. When the adjusting cylinder 41 moves relative to the filter screen 34, it is suitable for scraping away impurities in the mesh of the filter screen 34. A limiting post 310 is radially slidably provided on the inner wall of the limiting cylinder 32. A limiting groove adapted to the limiting post 310 is opened on the bottom side wall of the filter screen 34. When assembling the filter screen 34, one end of the filter screen 34 is inserted into the sliding groove 42, and the filter screen 34 is inserted into the adjusting cylinder 41 in a through state. The side walls of the sliding groove 42 clamp and limit the filter screen 34 from both the inner and outer sides. The adjusting cylinder 41 pushes the filter screen 34 to move into the limiting cylinder 32 until the limiting post 310 is inserted into the limiting groove. At this time, one end of the filter screen 34 is limited by the adjusting cylinder 41, and the other end is limited by the limiting post 310. The filter screen 34 cannot move within the limiting cylinder 32.

[0098] Reference Appendix Figure 7 When the filter screen 34 needs to be replaced, manually push the adjusting cylinder 41 into the limiting cylinder 32 until the side wall of the adjusting cylinder 41 abuts against the side wall of the limiting post 310. The adjusting cylinder 41 is suitable for pushing the limiting post 310 to retract away from the filter screen 34. At this time, because the mesh of the filter screen 34 is blocked, the friction between the adjusting cylinder 41 and the filter screen 34 increases. When the adjusting cylinder 41 moves quickly away from the limiting cylinder 32, it is suitable for driving the filter screen 34 to move outward synchronously.

[0099] Reference Appendix Figure 3 A tension spring 35 is provided on the inner wall of the end of the limiting cylinder 32 away from the spray head 33, and one end of the tension spring 35 is provided on the outer wall of the adjusting cylinder 41; wherein, after the thrust of the wind received by the adjusting cylinder 41 decreases, the tension spring 35 is adapted to drive the adjusting cylinder 41 to move away from the spray head 33.

[0100] Reference Appendix Figure 1 A drive motor 11 is provided on the air outlet side wall of the fan body 1, and one of the louvers 2 is connected to the drive motor 11. A pull rod 12 is raised and lowered at the air outlet of the fan body 1, and the side walls of several louvers 2 are hinged to the pull rod 12. When the drive motor 11 drives one louver 2 to rotate, the louver 2 is adapted to drive the pull rod 12 to move up or down, so as to drive the other louvers 2 to rotate synchronously.

[0101] Reference Appendix Figure 1Some embodiments provide a spraying device, including: a spraying device 3, which is disposed at the air outlet of a blower body 1 and connected to a water pipe 5; an adjusting component 4, which is slidably disposed near the blower body 1; the spraying device 3 includes a filter screen 34; wherein, during assembly, the adjusting component 4 pushes the filter screen 34 into the spraying device 3 until the inner end of the filter screen 34 is limited to the inner wall of the spraying device 3; if the wind force at the air outlet of the blower body 1 increases, the adjusting component 4 is pushed to slide into the spraying device 3, and the adjusting component 4 is adapted to scrape off impurities on the inner wall of the filter screen 34; when the adjusting component 4 moves inward to block the water outlet 50 of the water pipe 5, the adjusting component 4 is deformed by the water flow, and the adjusting component 4 is adapted to vibrate the filter screen 34 to shake off the impurities on the filter screen 34.

[0102] At least one embodiment also provides a method for operating a permanent magnet fan, the method comprising:

[0103] The louvers 2 rotate relative to the fan body 1 to adjust the airflow direction and flow rate of the air blown by the fan body 1 into the breeding shed; the water pipe 5 delivers water to the spray device 3, which is adapted to spray water in a mist into the breeding shed to adjust the humidity of the air in the breeding shed; when the adjusting component 4 is pushed to move away from the fan body 1, the adjusting component 4 moves relative to the filter screen 34 to scrape off impurities on the inner wall of the filter screen 34; when the adjusting component 4 moves to block the outlet 50 of the water pipe 5, the water flow pushes the adjusting component 4 to deform, and the adjusting component 4 is adapted to vibrate the filter screen 34 to shake off the impurities on the filter screen 34.
