Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, specifically relating to equipment for ranching, and particularly to a real-time monitorable hoisted permanent magnet fan for ranching and its assembly method. Background Technology

[0002] In ranching, ventilation is a crucial requirement. Related technologies utilize equipment such as fans for air exchange; negative pressure ventilation, a common method, creates negative pressure inside the ranch shed, with air flowing in through inlets and being expelled by fans under negative pressure.

[0003] Due to the special nature of negative pressure ventilation, the sealing requirements for the connection between the power cord and the fan motor are relatively high. However, the traditional connection between the power cord and the fan is not well sealed, and impurities in the air can enter the connection between the power cord and the fan, resulting in poor circuit connection stability. On the other hand, using glue or tape to seal the connection is not conducive to disassembly and maintenance.

[0004] Therefore, how to avoid poor sealing at the connection between the power cord and the fan and the inconvenience of disassembly are technical problems that urgently need to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one real-time monitorable hoisted permanent magnet fan for ranching and its assembly method.

[0007] In a first aspect, embodiments of this disclosure provide a real-time monitorable suspended permanent magnet fan for ranching, comprising:

[0008] The drive motor is located on one side of the fan;

[0009] The power cord has a positioning groove circumferentially formed on its outer wall, and a sealing ring is fitted inside the positioning groove.

[0010] An adjustment assembly is fitted onto the outer wall of the power cord and includes two opposing adjustment members that abut against a sealing ring.

[0011] During the process of inserting the end of the power cord into the connecting post of the drive motor, the adjusting component slides outward relative to the power cord.

[0012] When the adjusting component slides outward, it pulls the sealing ring to bend and deform, so that the sealing ring can be inserted into the gap between the power line and the connecting post.

[0013] After the adjusting component loosens the sealing ring, the sealing ring returns to its original shape under elastic action to seal the gap between the power line and the connecting post.

[0014] In one optional embodiment, a positioning block is provided on the left and right sides of the outer wall of the power cord near the positioning groove, and the positioning block abuts against the sealing ring;

[0015] The power cord has a receiving groove on the upper and lower sides near the positioning groove on its outer wall, and each receiving groove corresponds to an adjustment component.

[0016] In one alternative embodiment, the adjustment assembly includes an inner sleeve fitted onto the outer wall of the power cord.

[0017] The inner sleeve has two sliding grooves along the axial direction and an annular groove in the circumferential direction, and the sliding grooves are connected to the annular groove.

[0018] The adjusting component is slidably disposed within the sliding groove;

[0019] During the process of the power cord moving into the connecting post, the adjusting component retracts and slides into the sliding groove.

[0020] The outer end of the adjusting element abuts against the side wall of the inner sleeve, so that the sealing ring disengages from the side wall of the adjusting element.

[0021] In one optional embodiment, the adjusting member includes: a connecting rod that is slidably disposed in a sliding groove and protrudes from the inner sleeve;

[0022] The positioning rod is hinged to the inner wall of the connecting rod and is suitable for limiting the sealing ring;

[0023] The adjusting column is mounted on the outer wall of the connecting rod and is linked to the positioning rod.

[0024] Among them, the connecting rod retracts into the sliding groove until the adjusting column abuts against the side wall of the inner sleeve;

[0025] The adjusting column is compressed and retracts towards the positioning rod, causing the positioning rod to flip outward relative to the connecting rod, so that the sealing ring detaches from the side wall of the positioning rod.

[0026] In one optional embodiment, a connecting ring is fitted inside the annular groove, and the connecting ring is hollow inside;

[0027] When the connecting rod retracts into the sliding groove and abuts against the connecting ring, the connecting ring is adapted to expand and deform outward.

[0028] In one optional embodiment, an outer sleeve is fitted onto the outer wall of the inner sleeve, the inner wall of the outer sleeve abuts against the connecting ring, and the outer sleeve is threadedly adapted to the connecting post.

[0029] The connecting rod compresses the connecting ring to expand outward, thereby increasing the friction between the connecting ring and the outer sleeve.

[0030] Secondly, this disclosure also provides a wiring structure for a permanent magnet fan, including:

[0031] The power cord has a sealing ring fitted on its outer wall;

[0032] The inner sleeve is fitted onto the outer wall of the power cord and has two sliding grooves along the axial direction.

[0033] An adjusting element is slidably disposed in each sliding groove, and the adjusting element abuts against the sealing ring;

[0034] During the process of inserting the power cord into the connecting post, the adjusting component slides outward to pull the sealing ring to bend and deform, so that the sealing ring is inserted into the gap between the power cord and the connecting post.

[0035] After the adjusting component loosens the sealing ring, the sealing ring returns to its original shape to seal the gap between the power cord and the connecting post.

[0036] In one optional embodiment, a positioning block is provided on the left and right sides of the outer wall of the power cord near the sealing ring, and the positioning block abuts against the sealing ring;

[0037] The power cord has a receiving groove on the upper and lower sides near the sealing ring on its outer wall, and each receiving groove corresponds to an adjustment component.

[0038] In one optional embodiment, the adjusting member includes: a connecting rod that is slidably disposed in a sliding groove and protrudes from the inner sleeve;

[0039] The positioning rod is hinged to the inner wall of the connecting rod and is suitable for limiting the sealing ring;

[0040] The adjusting column is mounted on the outer wall of the connecting rod and is linked to the positioning rod.

[0041] Among them, the connecting rod retracts into the sliding groove until the adjusting column abuts against the side wall of the inner sleeve;

[0042] The adjusting column is compressed and retracts towards the positioning rod, causing the positioning rod to flip outward relative to the connecting rod, so that the sealing ring detaches from the side wall of the positioning rod.

[0043] In one optional embodiment, the inner sleeve has a circumferential groove, and a connecting ring is fitted inside the groove, the connecting ring being hollow inside.

[0044] When the connecting rod retracts into the sliding groove and abuts against the connecting ring, the connecting rod squeezes the connecting ring to expand and deform outward.

[0045] In one optional embodiment, an outer sleeve is fitted onto the outer wall of the inner sleeve, the inner wall of the outer sleeve abuts against the connecting ring, and the outer sleeve is threadedly adapted to the connecting post.

[0046] The connecting rod compresses the connecting ring to expand outward, thereby increasing the friction between the connecting ring and the outer sleeve.

[0047] Thirdly, this disclosure also provides an assembly method for a permanent magnet fan, the assembly method comprising:

[0048] During the process of inserting the end of the power cord into the connecting post of the drive motor, the adjusting component slides outward relative to the power cord.

[0049] When the adjusting component slides outward, it pulls the sealing ring to bend and deform, so that the sealing ring can be inserted into the gap between the power line and the connecting post.

[0050] After the adjusting component loosens the sealing ring, the sealing ring returns to its original shape under elastic action to seal the gap between the power line and the connecting post.

[0051] The beneficial effects of this invention are as follows: A real-time monitorable suspended permanent magnet fan for ranching and its assembly method, through the cooperation of a power cord, a sealing ring, and an adjusting component, allows the sealing ring to be stretched and deformed by the adjusting component during the connection process between the power cord and the connecting post of the drive motor. The sealing ring becomes elongated and thinner, allowing it to be inserted into the gap between the power cord and the connecting post. After the power cord is electrically connected to the drive motor, the adjusting component releases its restraint on the sealing ring, and the sealing ring returns to its original deformation under elastic action. This improves the airtightness between the power cord and the connecting post, preventing dust or impurities in the air from entering the connection between the connecting post and the power cord.

[0071] Research has revealed the following drawbacks of existing technologies: Air exchange in these technologies relies on equipment such as fans; and ventilation methods are categorized into negative pressure ventilation, positive pressure ventilation, and mixed ventilation. For negative pressure ventilation, a negative pressure is created within the ranch shed, with air flowing in through inlets and being exhausted by fans under negative pressure.

[0072] Due to the unique nature of negative pressure ventilation, the negative pressure fan needs to expel the air from the livestock shed under negative pressure during operation. Therefore, the air flowing through the negative pressure fan contains a significant amount of dust and impurities. Consequently, the sealing requirements for the connection between the power cord and the fan motor are very high. Traditional power cord connections to the fan are poorly sealed, allowing impurities in the air to enter the connection and leading to decreased circuit stability.

[0073] Therefore, how to avoid poor sealing at the connection between the power cord and the fan and the inconvenience of disassembly are technical problems that urgently need to be solved in this field.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] like Figures 1 to 7 As shown, at least one embodiment provides a real-time monitoring-enabled suspended permanent magnet fan 2 for ranching, comprising: a drive motor 1, which is disposed on one side of the fan 2; the fan 2 is suspended on the top of the ranch shed, and the drive motor 1 is connected to the fan 2 in a transmission connection, the drive motor 1 drives the fan 2 to rotate, so as to exhaust the air inside the ranch shed to the outside. According to the changes in temperature and humidity inside the ranch shed, the drive motor 1 can drive the fan 2 at different speeds to regulate the temperature and humidity inside the ranch shed. A power cord 3 has a positioning groove 30 circumferentially formed on its outer wall, and a sealing ring 5 is fitted inside the positioning groove 30; the end of the power cord is provided with a connector, and the inner wall of the connecting post 10 is provided with a plug groove adapted to the connector. When the connector is inserted into the plug groove, the power cord 3 is electrically connected to the drive motor 1.

[0078] Reference Appendix Figure 2 An adjusting component 4 is fitted onto the outer wall of the power cord 3 and includes two opposing adjusting members 40, which abut against the sealing ring 5. When the power cord 3 is horizontally inserted into the connecting post 10, the adjusting members 40 are adapted to limit the upper and lower sides of the sealing ring 5. When the adjusting members 40 abut against the end wall of the connecting post 10, the power cord 3 continues to be inserted into the connecting post 10, and the adjusting members 40 slide outward relative to the power cord 3. At this time, the adjusting members 40 pull the sealing ring 5 to bend outward. During the process of the end of the power cord 3 being inserted into the connecting post 10 of the drive motor 1, the adjusting members 40 slide outward relative to the power cord 3. When the adjusting members 40 slide outward, they pull the sealing ring 5 to bend and deform, so that the sealing ring 5 can be inserted into the gap between the power cord 3 and the connecting post 10. During the process of the sealing ring 5 being pulled outward and bent by the adjusting members 40, the sealing ring 5 is stretched and thinned, so that the sealing ring 5 can be inserted into the gap between the outer wall of the power cord 3 and the inner wall of the connecting post 10. After the adjusting component 40 loosens the sealing ring 5, the sealing ring 5 returns to its original shape under the action of elasticity, so as to seal the gap between the power line 3 and the connecting post 10.

[0079] Reference Appendix Figure 4 Through the cooperation of the power cord 3, the sealing ring 5, and the adjusting component 4, during the connection process between the power cord 3 and the connecting post 10 of the drive motor 1, the sealing ring 5 is stretched and deformed by the adjusting component 40, becoming longer and thinner, allowing it to be inserted into the gap between the power cord 3 and the connecting post 10. After the power cord 3 is electrically connected to the drive motor 1, the adjusting component 40 releases its restraint on the sealing ring 5, and the sealing ring 5 returns to its original shape under elastic action, improving the airtightness between the power cord 3 and the connecting post 10 and preventing dust or impurities in the air from entering the connection between the connecting post 10 and the power cord 3.

[0080] Reference Appendix Figure 3 A positioning block 31 is provided on the left and right sides of the outer wall of the power cord 3 near the positioning groove 30, and the positioning block 31 abuts against the sealing ring 5. A receiving groove 32 is provided on the upper and lower sides of the outer wall of the power cord 3 near the positioning groove 30, and one receiving groove 32 corresponds to one adjusting member 40. The extension line between the two positioning blocks 31 and the extension line between the two adjusting members 40 are perpendicular to each other. When the adjusting member 40 pulls the sealing ring 5 to bend outward, the two positioning blocks 31 play the role of limiting the sealing ring 5 to prevent the sealing ring 5 from completely detaching from the positioning groove 30.

[0081] Continue to refer to the appendix Figure 3 The adjusting component 4 includes an inner sleeve 41, which is fitted onto the outer wall of the power cord 3; the outer diameter of the inner sleeve 41 is not less than the outer diameter of the connecting post 10; during the process of inserting the power cord 3 into the connecting post 10, the end of the adjusting component 40 will abut against the end wall of the connecting post 10, and as the power cord 3 continues to be inserted into the connecting post 10, the adjusting component 40 is pushed by the connecting post 10 to retract and move into the inner sleeve 41.

[0082] Reference Appendix Figure 4 The inner sleeve 41 has two sliding grooves 42 along the axial direction and an annular groove in the circumferential direction, and the sliding grooves 42 are connected to the annular groove. The adjusting member 40 is slidably disposed in the sliding groove 42. During the movement of the power cord 3 into the connecting post 10, the adjusting member 40 retracts and slides into the sliding groove 42. During the retraction and sliding process, the adjusting member 40 pulls the sealing ring 5 to bend and deform, so that the sealing ring 5 can be inserted into the gap between the outer wall of the power cord 3 and the inner wall of the connecting post 10. The outer end of the adjusting member 40 abuts against the side wall of the inner sleeve 41, so that the sealing ring 5 disengages from the side wall of the adjusting member 40.

[0083] Continue to refer to the appendix Figure 3The adjusting component 40 includes: a connecting rod 401, which is slidably disposed within a sliding groove 42 and protrudes from an inner sleeve 41; when the power cord 3 is not inserted into the connecting post 10, the outer end of the connecting rod 401 protrudes from the end wall of the inner sleeve 41. A positioning rod 402, which is hinged to the inner wall of the connecting rod 401 and is adapted to limit the sealing ring 5; a torsion spring is sleeved at the hinge axis between the positioning rod 402 and the connecting rod 401, and the torsion spring is adapted to push the positioning rod 402 to flip it toward the connecting rod 401. An adjusting post 403, which is raised and lowered on the outer wall of the connecting rod 401 and is linked with the positioning rod 402; the adjusting post 403 is adapted to limit the positioning rod 402, and when the adjusting post 403 is not retracted into the connecting rod 401, the positioning rod 402 cannot flip relative to the connecting rod 401.

[0084] Reference Appendix Figure 6 A force F1 is applied to the power cord 3, causing it to move into the connecting post 10. The connecting rod 401 retracts into the sliding groove 42 until the adjusting post 403 abuts against the side wall of the inner sleeve 41; the adjusting post 403 is squeezed and retracts into the positioning rod 402, causing the positioning rod 402 to flip outward relative to the connecting rod 401, so that the sealing ring 5 disengages from the side wall of the positioning rod 402. The positioning rod 402 flips towards the side wall of the connecting rod 401. At this time, the positioning rod 402 can no longer limit the sealing ring 5, and the sealing ring 5 resets its deformation under its own elastic force. The sealing ring 5 changes from a stretched deformation state to a state perpendicular to the axis of the power cord 3, thereby improving the airtightness between the power cord 3 and the connecting post 10.

[0085] Continue to refer to the appendix Figure 3 To prevent the outer sleeve 6 from becoming loose relative to the connecting post 10, a connecting ring 43 is fitted inside the annular groove. The connecting ring 43 is hollow inside. When the connecting rod 401 retracts into the sliding groove 42 and abuts against the connecting ring 43, the connecting rod 401 is adapted to compress the connecting ring 43, causing it to expand and deform outward. The outer wall of the connecting ring 43 abuts against the inner wall of the outer sleeve 6. When the connecting ring 43 is not expanded and deformed, the outer sleeve 6 is adapted to rotate circumferentially relative to the power line 3.

[0086] Continue to refer to the appendix Figure 3 An outer sleeve 6 is fitted onto the outer wall of the inner sleeve 41, and the outer sleeve 6 is adapted to rotate circumferentially relative to the inner sleeve 41. The inner wall of the outer sleeve 6 abuts against the connecting ring 43, and the outer sleeve 6 is threadedly fitted to the connecting post 10. The connecting rod 401 compresses the connecting ring 43 outward to increase the friction between the connecting ring 43 and the outer sleeve 6. The outward expansion of the connecting ring 43 prevents vibration of the outer sleeve 6 during operation of the drive motor 1, thus avoiding loosening of the threads between the outer sleeve 6 and the connecting post 10, and improving the stability of the fixation between the outer sleeve 6 and the connecting post 10.

[0087] Reference Appendix Figure 5The adjusting element 40 is located on the inner ring of the outer sleeve 6. An outer limiting ring 60 is provided on the inner wall of the end of the outer sleeve 6 away from the connecting post 10, and an inner limiting ring 410 is provided on the outer wall of the inner sleeve 41. The outer limiting ring 60 is adapted to abut against the inner limiting ring 410. After the power cord 3 is connected to the connecting post 10, the outer sleeve 6 is rotated circumferentially to tighten the outer sleeve 6 with the thread on the outer wall of the connecting post 10. At this time, the outer limiting ring 60 abuts against the inner limiting ring 410.

[0088] Reference Appendix Figure 2 At least one embodiment provides a wiring structure for a permanent magnet fan 2, including: a power cord 3, with a sealing ring 5 sleeved on its outer wall; an inner sleeve 41, which is fitted onto the outer wall of the power cord 3 and has two sliding grooves 42 along the axial direction; an adjusting member 40 is slidably disposed in each sliding groove 42, the adjusting member 40 abutting against the sealing ring 5; wherein, during the process of inserting the power cord 3 into the connecting post 10, the adjusting member 40 slides outward to pull the sealing ring 5 to bend and deform, so that the sealing ring 5 is inserted into the gap between the power cord 3 and the connecting post 10; after the adjusting member 40 releases the sealing ring 5, the sealing ring 5 returns to its original deformation to seal the gap between the power cord 3 and the connecting post 10.

[0089] Reference Appendix Figure 2 At least one embodiment provides an assembly method for a permanent magnet fan, the assembly method comprising: during the process of inserting the end of the power cord 3 into the connecting post 10 of the drive motor 1, the adjusting member 40 slides outward relative to the power cord 3; when the adjusting member 40 slides outward, it pulls the sealing ring 5 to bend and deform, so that the sealing ring 5 is inserted into the gap between the power cord 3 and the connecting post 10; after the adjusting member 40 releases the sealing ring 5, the sealing ring 5 resets its deformation under the action of elasticity, so as to seal the gap between the power cord 3 and the connecting post 10.

[0090] In summary, during the insertion of the power cord 3 into the connecting post 10 of the drive motor 1, the adjusting member 40 moves along with the power cord 3 towards the connecting post 10, and abuts against the end wall of the connecting post 10. As the power cord 3 is gradually inserted into the connecting post 10, the adjusting member 40 is pushed by the end wall of the connecting post 10 to retract towards the inner sleeve 41. The adjusting member 40 pulls the sealing ring 5 to bend and deform, so that the sealing ring 5 is stretched and thinned, so that the sealing ring 5 can be inserted into the gap between the outer wall of the power cord 3 and the inner wall of the connecting post 10. When the adjusting post 403 is abutted by the end of the inner sleeve 41, as the connecting rod 401 continues to retract into the inner sleeve 41, the adjusting post 403 retracts into the connecting rod 401, so that the positioning rod 402 gradually flips towards the connecting rod 401 with the hinge point as the axis. At this time, the positioning rod 402 releases the limit on the sealing ring 5, and the sealing ring 5 resets its deformation under its own elastic force. After the power cord 3 is plugged into and fixed to the connecting post 10 and electrically connected, the outer sleeve 6 is rotated circumferentially. The outer sleeve 6 is screwed into the connecting post 10 so that the outer limiting ring 60 and the inner limiting ring 410 abut against each other. The connecting rod 401 squeezes the connecting ring 43 to expand and deform outward, so as to increase the friction between the inner wall of the outer sleeve 6 and the connecting ring 43 and prevent the outer sleeve 6 from rotating in the opposite direction relative to the inner sleeve 41.
