Description

Technical Field

[0001] This invention relates to the field of pig farming technology, specifically to an anti-climbing fence structure for raising Meishan pigs. Background Technology

[0002] In intensive farming environments, pigs may exhibit climbing behaviors due to a lack of sufficient space to move around or an inability to express normal behaviors (such as rooting and exploring). Climbing can lead to injuries, especially when the climbing equipment is unstable or the surface is too slippery, causing slips, abrasions, or fractures. It can also lead to pigs escaping or damaging pen facilities, increasing management difficulties. Frequent climbing behavior can affect pigs' feeding and resting time, thereby impacting their production performance.

[0003] To address the aforementioned issues, an anti-climbing pigpen has emerged on the market, comprising several fencing mechanisms. Each fencing mechanism includes barriers, foldable pulleys mounted on the barriers, and spiked components mounted on the barriers. In use, the device connects adjacent barriers via connectors, forming a rectangular fence. When pigs attempt to climb, the spikes on the spiked components pierce the pigs, causing discomfort and forcing them to move away from the enclosure.

[0004] The above-mentioned device has the following problems in actual use: the presence of spikes may cause physical injury to pigs, and if the spikes pierce the skin, they can easily cause local trauma, which can become a gateway for bacterial invasion and may lead to serious infections such as suppuration, septicemia or tetanus, thus having an adverse effect on pig farming. Summary of the Invention

[0005] This invention provides an anti-climbing fence structure for raising Meishan pigs, in order to solve the problem that the presence of sharp spikes in existing anti-climbing pigpens can easily cause injury to pigs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-climbing fence structure for raising Meishan pigs, comprising several fence mechanisms; the fence mechanism includes enclosure blocks and protective components disposed on the enclosure blocks; a connecting block is provided between two adjacent enclosure blocks, and the two ends of the connecting block are detachably connected to the two enclosure blocks respectively; the protective components include a protective block, a first electrode plate, a second electrode plate, a third electrode plate, a buzzer, a fixing block, a stop block, a first chamber opened in the enclosure block, a sliding hole opened on the enclosure block, a limiting hole opened on the fixing block, and a power unit for driving the stop block to move closer to the protective block; The sliding hole communicates with the first chamber; the protective block is slidably connected to the sliding hole; the first electrode plate is fixedly connected to the protective block; the second and third electrode plates are both fixedly connected to the first chamber, and the second and third electrode plates are both located on the movement trajectory of the first electrode plate; the buzzer is fixedly connected to the surrounding block; the first electrode plate, the second electrode plate, the buzzer, and the power supply are connected in series via wires to form a series circuit; the first electrode plate, the third electrode plate, the power unit, and the power supply are connected in series via wires to form a series circuit; the fixed block is fixedly connected to the surrounding block; the stop block is slidably connected to the surrounding block, and the stop block faces the limiting hole; the limiting hole is provided with anti-slip texture.

[0007] The principles and advantages of this scheme are: When Meishan pigs attempt to climb the enclosure during rearing, the enclosure slides under pressure, triggering a circuit that then sounds a buzzer, providing immediate feedback. This sound alerts or frightens the pigs, stopping their climbing and thus preventing them from climbing. Furthermore, through conditioned reflex mechanisms, long-term behavioral correction is achieved. After repeated exposure, the pigs associate climbing with unpleasant noise and actively reduce this behavior.

[0008] 2. After the stop block and the protective block come into contact, the sliding position of the protective block will be locked, thereby maintaining continuous contact of the electrode plates and ensuring that the servo motor remains powered, forming a self-locking feedback loop. This mechanism further enhances the stability of the system and the continuity of behavioral intervention based on the original audible and visual warnings.

[0009] The protective block slides under the pressure of the pig climbing, causing the first electrode to simultaneously contact the second and third electrode plates, triggering not only the buzzer but also the power unit. The stop block slides into the limiting hole and abuts against the protective block, preventing it from retracting due to elastic reset or weakening of external force, thus avoiding premature separation of the first electrode plate and ensuring the continuous effectiveness of the alarm and locking actions.

[0010] Once the stop block engages with the limiting hole, it physically limits the protective block, ensuring the system remains active even if the pig stops applying force. This "one-time trigger, continuous response" design effectively prevents pigs from quickly escaping after a brief attempt. Because the stop block maintains the protective block's position, farm workers have ample time to respond after hearing the beep, without worrying about the system automatically resetting, causing the alarm to disappear and the potential hazard to reappear.

[0011] 3. The anti-slip texture is designed to prevent the fence from being disturbed by impacts from pigs feeding in a farming environment. By increasing the roughness of the contact surface, the anti-slip texture effectively suppresses the slight displacement of the stop block within the limiting hole, ensuring its secure locking. Furthermore, the anti-slip texture enhances the mechanical interlocking strength, maintaining a stable fit between the stop block and the limiting hole even under long-term, frequent triggering or complex environments such as moisture or oil stains, reducing the risk of failure due to wear.

[0012] Furthermore, it also includes a guide section; the guide section includes a guide shaft, a guide wheel, a second chamber opened on the enclosure block, and a guide hole opened on the second chamber; the guide shaft is rotatably connected to the second chamber; the guide wheel is fixedly connected to the guide shaft; the guide hole communicates with the sliding hole, and the guide wheel passes through the guide hole and is in contact with the protective block.

[0013] The guide wheel is in contact with the protective block, which changes the sliding friction between the protective block and the sliding hole wall into rolling friction, greatly reducing the resistance to movement. This allows the protective block to slide smoothly under slight external force, thus triggering the electrode plate connection more promptly.

[0014] In complex aquaculture environments, factors such as dust and moisture can exacerbate friction issues. The presence of guide wheels enhances the system's resistance to environmental disturbances, ensuring a stable response to every climbing trigger and preventing failure due to mechanical obstruction.

[0015] Furthermore, it also includes an auxiliary part that moves synchronously with the stop block; the auxiliary part includes an auxiliary block, a third chamber opened in the fixed block, an auxiliary hole opened in the third chamber, and a power unit for driving the auxiliary block to move vertically; the auxiliary block is slidably connected to the auxiliary hole; and the protective block is located on the movement trajectory of the auxiliary block.

[0016] Based on the lateral clamping of the stop block against the side wall, a vertical clamping force is introduced to form a "lateral + vertical" two-way locking mechanism. Therefore, by the auxiliary block pressing the protective block vertically from above, multi-point coordinated limiting can be formed, significantly enhancing the constraint stiffness and anti-loosening ability of the protective block, thus further improving the stability and reliability of the entire anti-climb trigger structure.

[0017] Furthermore, because the protective block is more firmly fixed, the adhesion between the first electrode plate and the second and third electrode plates can be maintained for a long time, avoiding circuit interruption due to loose contact.

[0018] Furthermore, the auxiliary part also includes an auxiliary unit; the auxiliary unit includes a connecting block, a side plate, a side block, a conical shaft, a rubber layer, a conical hole on the side block, and a side hole on the fixed block; the connecting block is slidably connected to the side hole; both ends of the connecting block are fixedly connected to the auxiliary block and the side plate respectively; the side block is fixedly connected to the side plate; the rubber layer is fixedly connected to the conical hole; the conical shaft is fixedly connected to the guide shaft, and the conical shaft is located on the movement trajectory of the conical hole.

[0019] As the auxiliary block moves downwards, it drives the side blocks to move synchronously, causing the conical hole to slide towards the position of the conical shaft. Due to the properties of the rubber layer, as the stroke progresses, the gap between the conical hole and the conical shaft gradually decreases, generating a self-tightening effect, ultimately fixing the guide shaft firmly and preventing the guide wheel from rotating. Once the guide wheel is locked, it cannot roll, effectively "freezing" the sliding path of the protective block at the trigger position, preventing it from retracting due to elastic reset or the disappearance of external force, and ensuring continuous contact of the electrode sheet.

[0020] Furthermore, the auxiliary part also includes a linkage unit; the linkage unit includes a first wedge, a second wedge, a through block, a linkage block, a through hole on the auxiliary block, and a linkage hole on the linkage block; the first wedge is fixedly connected to the third chamber; the second wedge is fixedly connected to the through block, and the first wedge is located on the movement trajectory of the second wedge; the through block is slidably connected to the through hole; the linkage block is fixedly connected to the surrounding block, and the linkage hole is located on the movement trajectory of the through block.

[0021] When the auxiliary block and the protective block abut against each other, the through block slides into the linkage hole, which enables mechanical linkage locking between the auxiliary block and the surrounding block, further enhancing the constraint stability of the protective block and the overall anti-loosening capability of the system. After the auxiliary block completes the vertical downward pressing, the horizontal sliding action of the through block rigidly connects the auxiliary block to the outer structure (surrounding block), forming a "spatial multi-point anchoring" effect.

[0022] Furthermore, since the auxiliary block is mechanically locked, its downward pressure on the protective block is maintained for a long time, thereby ensuring that the protective block will not fall out of the trigger state due to loosening, and maintaining reliable contact between the first electrode plate and the second and third electrode plates.

[0023] Furthermore, the linkage unit also includes a third wedge, a vertical block, a fourth wedge, an inclined block, and a vertical hole in the third chamber; the third wedge is fixedly connected to the stop block; the vertical hole communicates with the limiting hole, and the vertical block is slidably connected to the vertical hole; the fourth wedge is located in the limiting hole, the fourth wedge is fixedly connected to the vertical block, and the fourth wedge is located on the movement trajectory of the third wedge; the inclined block is fixedly connected to the vertical block, and the through block is located on the movement trajectory of the inclined block.

[0024] The inclined block presses vertically against the through block from below, effectively preventing the through block from loosening or coming out of the linkage hole, further improving the reliability of the mechanical locking and the overall anti-disturbance capability of the system. After the through block completes its sliding action, this setting forms a "top-pressing and bottom-supporting" clamping structure through the support force from the bottom, significantly enhancing the stability of the connection.

[0025] Furthermore, in the breeding environment, the enclosure block may experience slight movement due to impacts or vibrations from the pigs feeding on it. The clamping block holds the through block from below, providing rigid support and preventing the through block from slipping out of the linkage hole due to external force or vibration, thus ensuring the locking state remains effective for a long time.

[0026] Meanwhile, since the position of the through block is firmly fixed, the auxiliary block cannot rebound, thus ensuring that its vertical pressing force on the protective block is not interrupted, thereby further maintaining stable contact between the first electrode plate and the second and third electrode plates.

[0027] Furthermore, the power unit includes a servo motor, a power shaft, a gear, a rack, a side groove on the protective block, and a power hole in the second chamber; the servo motor is fixedly connected to the second chamber; the power shaft is rotatably connected to the second chamber and fixedly connected to the output shaft of the servo motor; the gear is fixedly connected to the power shaft; the rack is fixedly connected to the side groove; the gear passes through the power hole and meshes with the rack.

[0028] After the servo motor is powered on, its output shaft drives the power shaft to rotate. During the rotation of the power shaft, the gears rotate synchronously. During the rotation of the gears, through the meshing of the gears and rack, the rack drives the stop block to move towards the position of the protective block and press against it.

[0029] Furthermore, the power unit includes a screw, a guide rod, a nut seat, and a power block; the screw is fixedly connected to the power shaft; the guide rod is fixedly connected to the second chamber; the nut seat is threadedly connected to the screw and slidably connected to the guide rod; both ends of the power block are fixedly connected to the nut seat and the auxiliary block, respectively.

[0030] During the rotation of the power shaft, the screw rotates synchronously. During the rotation of the screw, the nut seat drives the power block to move vertically along the length of the guide rod. Attached Figure Description

[0045] The power unit includes a screw 27, a guide rod 28, a nut seat 29, and a power block 30; the screw 27 is fixedly connected to the power shaft 24; the guide rod 28 is fixedly connected to the second chamber 34; the nut seat 29 is threadedly connected to the screw 27 and slidably connected to the guide rod 28; the two ends of the power block 30 are fixedly connected to the nut seat 29 and the auxiliary block 11, respectively.

[0046] Specific implementation process: When a Meishan pig attempts to climb enclosure 1 during rearing, protective block 3 is pressed and slides, triggering the first electrode plate 4 and the second electrode plate 5 to come into contact, thus connecting the circuit. The buzzer 7 then sounds, providing immediate feedback. This sound alerts or frightens the pig, causing it to stop climbing, thus preventing it from doing so. Furthermore, through a conditioned reflex mechanism, long-term behavioral correction is achieved. After repeated exposure, the pig will associate climbing with unpleasant noise and actively reduce such behavior.

[0047] As the first electrode plate 4 and the third electrode plate 6 come into contact, the third electrode plate 6 triggers the servo motor 32 to be energized. After the servo motor 32 is energized, its output shaft drives the power shaft 24 to rotate. During the rotation of the power shaft 24, the gear 25 rotates synchronously. During the rotation of the gear 25, through the meshing of the gear 25 and the rack 26, the rack 26 drives the stop block 9 to move towards the position of the protective block 3 and press against the protective block 3.

[0048] After the stop block 9 abuts against the protective block 3, it locks the sliding position of the protective block 3, thereby maintaining continuous contact of the electrode plates and ensuring that the servo motor 32 remains energized, forming a self-locking feedback loop. This mechanism further enhances the stability of the system and the continuity of behavioral intervention based on the original audible and visual warnings.

[0049] Furthermore, once the stop block 9 engages with the limiting hole, it effectively physically limits the protective block 3, ensuring the system remains active even if the pig stops applying force. This "one-time trigger, continuous response" design effectively prevents pigs from quickly escaping after a brief attempt. Because the stop block 9 maintains the position of the protective block 3, farm workers have ample time to respond after hearing the beep, without worrying about the system automatically resetting, causing the alarm to disappear and the potential hazard to reappear.

[0050] The anti-slip texture on the stop block 9 while it is positioned within the limiting hole is designed to prevent impacts from pigs feeding in a livestock environment. By increasing the roughness of the contact surface, the anti-slip texture effectively suppresses minor displacement of the stop block 9 within the limiting hole, ensuring its secure locking. Furthermore, the anti-slip texture enhances the mechanical interlocking strength, maintaining a stable fit between the stop block 9 and the limiting hole even under frequent triggering or in complex environments such as dampness or oil stains, reducing the risk of failure due to wear.

[0051] When the protective block 3 is located inside the sliding hole, the guide wheel 10 is in contact with the protective block 3, which transforms the original sliding friction between the protective block 3 and the sliding hole wall into rolling friction, greatly reducing the motion resistance. This allows the protective block 3 to slide smoothly under slight external force, thereby triggering the electrode plate connection more promptly.

[0052] Meanwhile, in complex aquaculture environments, factors such as dust and moisture can exacerbate friction problems. The presence of guide wheels 10 enhances the system's resistance to environmental disturbances, ensuring a stable response to every climbing trigger and preventing failure due to mechanical obstruction.

[0053] During the rotation of the power shaft 24, the screw 27 rotates synchronously. During the rotation of the screw 27, the nut seat 29 drives the power block 30 to move synchronously along the length of the guide rod 28. During the movement of the power block 30, the power block 30 drives the auxiliary block 11 to move synchronously through the connecting block 12.

[0054] Therefore, based on the lateral clamping of the stop block 9 against the side wall, the vertical clamping force of the auxiliary block 11 is introduced to form a "lateral + vertical" two-way locking mechanism. During the period when the auxiliary block 11 vertically squeezes the protective block 3 from above, multi-point coordinated limiting can be formed, which significantly enhances the constraint stiffness and anti-loosening ability of the protective block 3, that is, further improves the stability and reliability of the entire anti-climb trigger structure.

[0055] Furthermore, because the protective block 3 is more firmly fixed, the adhesion between the first electrode plate 4 and the second and third electrode plates 6 can be maintained for a long time, avoiding circuit interruption due to loose contact.

[0056] When the auxiliary block 11 moves downward, it drives the side block 14 to move synchronously, causing the conical hole to slide towards the position of the conical shaft 15. Due to the characteristics of the rubber layer, as the stroke progresses, the gap between the conical hole and the conical shaft 15 gradually decreases, generating a self-tightening effect, which ultimately firmly fixes the guide shaft 35, preventing the guide wheel 10 from rotating. Once the guide wheel 10 is locked, it cannot roll, which is equivalent to "freezing" the sliding path of the protective block 3 at the trigger position, effectively preventing it from retracting due to elastic reset or the disappearance of external force, ensuring continuous contact of the electrode sheet.

[0057] During the contact between the auxiliary block 11 and the protective block 3, the second wedge 17, under the action of the first wedge 16, will drive the through block to slide into the linkage hole 19. By sliding the through block into the linkage hole 19, mechanical linkage locking between the auxiliary block 11 and the surrounding block 1 can be achieved, further enhancing the constraint stability of the protective block 3 and the overall anti-loosening capability of the system. This design, after the auxiliary block 11 completes its vertical downward pressing, uses the horizontal sliding action of the through block to rigidly connect the auxiliary block 11 to the outer structure (surrounding block 1), forming a "multi-point spatial anchoring" effect.

[0058] Furthermore, since the position of the auxiliary block 11 is mechanically locked, its downward pressure on the protective block 3 can be maintained for a long time, thereby ensuring that the protective block 3 will not be released from the trigger state due to loosening, and maintaining reliable contact between the first electrode plate 4 and the second and third electrode plates 6.

[0059] Simultaneously, while the stop block 9 slides into the limiting hole, the third wedge block 20 presses against the fourth wedge block 22, which in turn drives the vertical block 21 to move vertically upward. During the movement of the vertical block 21, the inclined block 23 moves synchronously. During the movement of the inclined block 23, it vertically presses against the through block from below, effectively preventing the through block from loosening or coming out of the linkage hole 19, further improving the reliability of the mechanical locking and the overall anti-disturbance capability of the system. This setting, after the through block completes its sliding action, forms a "pressing down and supporting up" clamping structure through the support force from the bottom, significantly enhancing the stability of the connection.

[0060] Furthermore, in the breeding environment, the enclosure block 1 may experience slight movement due to impacts or vibrations from the feed pigs. The clamping block presses against the through block from below, providing rigid support and preventing the through block from slipping out of the linkage hole 19 due to external force or vibration, thus ensuring the long-term effectiveness of the locking state.

[0061] Meanwhile, since the position of the through block is firmly fixed, the auxiliary block 11 cannot rebound, thus ensuring that its vertical pressing force on the protective block 3 is not interrupted, thereby further maintaining stable contact between the first electrode plate 4 and the second and third electrode plates 6.

[0062] In summary, through the combined action of the buzzer 7, the stop block 9, and the auxiliary block 11, a three-level anti-climbing mechanism of "audio-visual warning - mechanical limit - multi-directional locking" is formed, thereby significantly improving the suppression effect on the climbing behavior of Meishan pigs and the reliability of the system.
