Description

Technical Field

[0001] This invention relates to the field of power auxiliary equipment technology, and in particular to an animal herder for power equipment. Background Technology

[0002] Existing power equipment, such as transmission towers, is prone to animal climbing because it is often used in the field and lacks real-time human monitoring and protection.

[0003] Animals climbing power transmission towers essentially disrupts the normal operation of these towers. On the one hand, the animals' own electrical conductivity or contact with key components such as conductors and insulators during the climb can cause short circuits, grounding, and other power failures, affecting the stability and safety of power transmission. On the other hand, the animals' climbing can cause mechanical wear to the tower's structure, such as the pole and connectors. Over time, this wear and tear can reduce the tower's structural stability, creating safety hazards and ultimately affecting the long-term reliable operation of the power system.

[0004] To address the problem of animals climbing power transmission towers, existing technologies typically employ fixed spike structures. For example, Chinese patent CN206851876U discloses a stainless steel snake-proof device, which includes a C-shaped steel plate covering the power transmission tower pole and barbs evenly distributed on the outer surface of the steel plate to prevent snakes from climbing.

[0005] However, in the transportation process, the exposed spikes of the existing fixed spike structure are easily damaged by collisions and friction, causing its anti-climbing physical function to fail and affecting the normal use of the device. In the installation process, the exposed spikes can easily scratch the installation personnel, affecting both efficiency and personal safety. In the operation and maintenance of power transmission towers, the exposed spikes may also scratch the maintenance personnel, increasing the safety risks and operational difficulties of operation and maintenance. Summary of the Invention

[0006] Therefore, it is necessary to provide an animal deterrent for power equipment to address the inconvenience of transportation and installation of the current fixed spike structure, as well as the potential increase in safety risks and operational difficulties during the operation and maintenance of power transmission towers.

[0007] The above objectives are achieved through the following technical solutions: An animal deterrent device for electrical equipment includes a deterrent unit for deterring animals. The deterrent unit includes a base, a support member rotatably mounted on top of the base, and a rotating shaft mounted on top of the support member and capable of rotating synchronously with the support member. The rotating shaft has a plurality of spikes along its axial direction on its peripheral sidewall, each spike having a spike segment to prevent animals from climbing. The support member is slidable along the axial direction of the rotating shaft and has corresponding locked and unlocked positions before and after sliding. In the locked position, the rotational freedom of the support member is locked; in the unlocked position, the rotational freedom of the support member is unlocked. The spikes have corresponding exposed and retracted positions before and after rotating with the rotating shaft. In the exposed position, the spike segments extend away from the base and are perpendicular to the rotating shaft; in the retracted position, the spike segments extend towards the base, with the extension direction forming a preset angle with the rotating shaft, and are inserted into the space formed between the rotating shaft and the top of the base.

[0008] Furthermore, the top of the base has a first slot that is parallel to the rotation axis and has a strip-shaped structure; the support is a strip-shaped structure that is parallel to the rotation axis and has an arc surface at the bottom. The arc surface at the bottom of the support matches the shape of the first slot and fits into the first slot.

[0009] Furthermore, one of the bottom end of the first slot and the bottom end of the support member is provided with a protrusion, and the other is provided with a second slot that matches the shape of the protrusion. In the locked position, the protrusion and the second slot form a plug-in engagement to restrict the rotation of the support member. In the unlocked position, the protrusion and the second slot disengage from the plug-in engagement and restore the rotation of the support member.

[0010] Furthermore, a row of guide wedges is provided on both opposite sides of the first slot. The guide wedges in the same row are arranged along the extension direction of the support and are respectively set to correspond to the spikes. Each guide wedge has a guide slope that can form a guiding engagement with the spike segment of the spike. During the process of the spike switching from the exposed position to the retracted position, under the guidance of the guide slope, the spike segment of the spike elastically swings around its proximal end until it swings to a preset angle with the rotation axis.

[0011] Furthermore, both ends of the rotating shaft are coaxially provided with rotating columns, and each rotating column is fitted with a support knob. The support knob is mounted on the base and can rotate synchronously with the rotating column, and can drive the rotating shaft to rotate synchronously axially, so that the rotating shaft can also rotate relative to the support.

[0012] Furthermore, a strip-shaped third slot is provided parallel to the top of the support member. The cross-sectional shape of the third slot is arc-shaped. A row of first limiting grooves is provided on both opposite sides of the third slot. The first limiting grooves in the same row are arranged at intervals along the extension direction of the support member, and the first limiting grooves in different rows are correspondingly arranged along the extension direction of the support member. A first limiting protrusion is formed between adjacent first limiting grooves in the same row. The rotating shaft includes a main shaft part located at the center and a secondary shaft part located on the outer periphery and sleeved on the main shaft part. The shape of the main shaft part matches the third slot and is fitted into the third slot. The cross-sectional shape of the secondary shaft part is arc-shaped. The device is fan-shaped and has a row of second limiting grooves on both sidewalls of the secondary shaft. The second limiting grooves in the same row are spaced apart along the axial direction of the secondary shaft, while the second limiting grooves in different rows are correspondingly arranged along the axial direction of the secondary shaft. A second limiting protrusion is formed between adjacent second limiting grooves in the same row. The cross-section of the secondary shaft where the second limiting protrusion is located and the cross-section of the third slot where the first limiting protrusion is located together form a complete circle. In the locked position, the first limiting protrusion and the second limiting protrusion correspond and abut. In the released position, the first limiting protrusion and the second limiting groove are correspondingly arranged, and the second limiting protrusion and the first limiting groove are correspondingly arranged.

[0013] Furthermore, the base and the support knob are provided with multiple limiting holes at the contact position. The multiple limiting holes are partially overlapped along the direction perpendicular to the axis of rotation, so that the support knob forms multiple movable points to accommodate spikes of different lengths.

[0014] Furthermore, the bottom of the base is provided with an elastic deformation layer to adapt to different mounting surfaces.

[0015] Furthermore, there are multiple driving units, which are connected side by side along the circumference to form a ring structure fitted onto the pole of the power equipment.

[0016] Furthermore, the ring structure formed by multiple driving units connected side by side along the circumference can be fitted onto power equipment poles with L-shaped, circular, or rectangular cross-sections.

[0017] The beneficial effects of this invention are: This invention relates to an animal deterrent device for power equipment. By configuring a base, support, rotating shaft, and spikes, and utilizing the movement of the support, rotating shaft, and spikes, during transportation, installation, and maintenance of transmission towers, adjusting the support to the unlocked position facilitates adjusting the spikes to the retracted position, thus avoiding damage to the spikes and preventing injury to operators, ensuring safety. During animal deterrence, adjusting the spikes to the exposed position and then adjusting the support to the locked position ensures the spikes are stable, thereby guaranteeing deterrence performance.

[0018] Furthermore, by setting a rotating column and a matching support knob, and utilizing the characteristic that the support knob can drive the rotating shaft to move synchronously axially, in the locked position, the rotating shaft and the support rotate synchronously, facilitating the adjustment of the position of the spike; in the unlocked position, the rotating shaft and the support can rotate relative to each other, so that under external force (such as wind or animal contact), the rotating shaft can drive the spike to rotate, thereby changing the circumferential position of the spike. This not only increases the difficulty for animals to adapt and enhances the flexibility of protection, but also allows for the cleaning of debris, achieving self-cleaning and maintaining the continuity of protection.

[0019] Furthermore, by setting multiple driving units, and connecting them side by side along the circumference to form a ring structure that is fitted onto the pole of the power equipment, it can adapt to various installation surfaces, which helps to improve applicability. Moreover, when a driving unit is damaged, the damaged driving unit can be replaced individually, which can improve the convenience of maintenance and avoid material waste.

[0020] Furthermore, by setting the spikes and the rotating shaft to be detachably connected, and by having multiple rotating grooves, and by utilizing multiple limiting holes partially overlapping in a direction perpendicular to the axis of the rotating shaft, the support knob has the characteristic of forming multiple movable points. By changing the movable points of the support knob, the distance between the rotating shaft and the base can be changed, thereby adapting the length of the spikes that can be accommodated between them to the types of animals that actually need protection on site, thus achieving targeted protection.

[0026] The following reference Figures 1 to 4 as well as Figure 15 and Figure 16 The present invention describes an animal deterrent device for power equipment, which is particularly suitable for installation on power equipment, such as the pole of a transmission tower, to prevent animals from climbing. Of course, it is also suitable for installation in similar outdoor scenarios where animals need to be prevented from climbing.

[0027] Specifically, the animal deterrent device of the power equipment is configured to include a deterrent unit for deterring animals. The deterrent unit includes a base 1, a support 2 rotatably mounted on the top of the base 1, and a rotating shaft 3 mounted on the top of the support 2. The rotating shaft 3 can rotate synchronously with the support 2. Several spikes 4 are provided on the circumferential sidewall of the rotating shaft 3 along its own axial direction.

[0028] The base 1 comprises a base plate 11 and two side plates 12. The base plate 11 is a strip structure and is horizontally positioned. The two side plates 12 are perpendicular to the base plate 11, parallel to each other, and are respectively located at both ends of the top of the base plate 11. The support member 2 is rotatably positioned on top of the base plate 11 during installation, and is located between the two side plates 12. The rotating shaft 3 is parallel to the base plate 11 during installation, located above the base plate 11, and is positioned between the two side plates 12.

[0029] The spike portion 4 has an open ring 41 and multiple spike segments 42. The spike segments 42 can be pagoda-shaped or triangular, and are located on the outer peripheral wall of the open ring 41, extending radially along the open ring 41. The multiple spike segments 42 are arranged circumferentially around the open ring 41 to avoid interference. The open ring 41 and spike segments 42 can be a single piece, facilitating stamping. To facilitate the installation of the spike portion 4, multiple mounting grooves 321 are provided on the peripheral sidewall of the rotating shaft 3. The mounting grooves 321 are fan-shaped and coaxial with the rotating shaft 3, and are arranged axially around the rotating shaft 3. The shape of the open ring 41 matches the shape of the mounting grooves 321, and it is inserted into the mounting grooves 321 during installation.

[0030] The support member 2 can slide along the axial direction of the rotating shaft 3, and has corresponding locked and unlocked positions before and after sliding. The spike 4 has corresponding exposed and retracted positions before and after rotating with the rotating shaft 3.

[0031] In the transportation and installation of animal deterrents for power equipment and the maintenance of transmission towers, the support component 2 is first adjusted to the unlocked position. At this time, the rotational freedom of the support component 2 is unlocked, and it can rotate freely. Then, the support component 2 drives the rotating shaft 3 and the spike 4 to rotate to the retracted position. At this time, the spike section 42 of the spike 4 extends towards the base 1, and the extension direction forms a preset angle with the rotating shaft 3, and inserts into the space formed between the rotating shaft 3 and the top of the base 1. This can effectively avoid structural damage to the spike section 42 due to collision during transportation, and at the same time eliminate the risk of scratches to installation and maintenance personnel caused by the spike section 42, thus improving the safety of the entire process.

[0032] In the animal repelling process, the support member 2 first drives the rotating shaft 3 and the spike 4 to rotate to the exposed position. At this time, the spike section 42 of the spike 4 extends away from the base 1, and its spike section 42 and the rotating shaft 3 are set perpendicularly. Then, the support member 2 is adjusted to the locked position. At this time, the rotational freedom of the support member 2 is locked, ensuring that the anti-climb structure is stable and reliable, and continuously maintaining the animal repelling effect.

[0033] In one embodiment, to enable the movable setting of the support member 2, a first slot 111 is provided on the top of the base 1. The first slot 111 is a strip structure and is arranged parallel to the rotation axis 3. The first slot 111 is specifically located on the top of the base plate 11, and its two ends are in contact with the side plate 12 respectively. The support member 2 is a strip structure parallel to the rotation axis 3, and has an arc surface at the bottom. The arc surface at the bottom of the support member 2 matches the shape of the first slot 111 and is fitted into the first slot 111. Under the guidance of the first slot 111, the support member 2 can slide along the rotation axis 3 and rotate on the base 1.

[0034] In one embodiment, to enable the support member 2 to switch between the locked and unlocked positions, a protrusion 13 can be provided at the bottom end of the first slot 111, near one of the side plates 12. The protrusion 13 can be a strip-shaped structure, parallel to the base plate 11, and located in the middle of the first slot 111. A second slot 21 is provided at the bottom end of the support member 2, and the second slot 21 matches the shape of the protrusion 13. Guided by the first slot 111, during the process of the support member 2 sliding axially along the rotation axis 3, when the support member 2 is in the locked position, the protrusion 13 and the second slot 21 form a plug-in engagement, restricting the rotation of the support member 2. When the support member 2 is in the unlocked position, the protrusion 13 and the second slot 21 disengage from the plug-in engagement, and the rotation of the support member 2 is restored.

[0035] In other embodiments, in order to enable the support member 2 to switch between the locked position and the unlocked position, the insertion protrusion 13 can also be set at the bottom end of the support member 2; the second slot 21 is opened at the bottom end of the first slot 111, that is, near one of the side plates 12; its working principle is the same as described above, and will not be repeated here.

[0036] In one embodiment, to enable the switching of the spike 4 between the exposed position and the retracted position, a row of guide wedges 14 is provided on both opposite sides of the first slot 111. The guide wedges 14 in the same row are arranged along the extension direction of the support member 2 and are respectively provided corresponding to the spike 4. The guide wedges 14 are plate-shaped structures, and their plate surfaces are perpendicular to the plate surfaces of the bottom plate 11 and the side plate 12. The shape of the guide wedges 14 is a right triangle, with its right-angled side parallel to the side plate 12 and its hypotenuse close to the side where the insertion protrusion 13 is located. Each guide wedge 14 has a guide slope 141, which can form a guiding engagement with the spike segment 42 of the spike 4. The guide slope 141 is the side wall surface where the hypotenuse of the guide wedge 14 is located.

[0037] During use, when the support member 2 is in the unlocked position, the spike 4 corresponds to the guide slope 141. As the spike 4 is rotated to the retracted position by the support member 2 and the rotating shaft 3, under the guidance of the guide slope 141, the spike segment 42 of the spike 4 makes an elastic swinging motion around its proximal end, that is, the connection point on the open ring 41, until it swings to form a preset angle with the rotating shaft 3. As the rotating shaft 3 rotates continuously, the multiple spike segments 42 of the spike 4 undergo the above-mentioned elastic swinging motion in sequence. When the spike 4 rotates to the retracted position, the ends of the multiple spike segments 42 of the spike 4 rub against the bottom of the first slot 111, thereby locking the rotation state of the rotating shaft 3.

[0038] During the process of rotating the shaft 3 and the spike 4 to the exposed position by the support member 2, the spike section 42 of the spike 4 is reset under the action of elasticity.

[0039] It is understandable that, in order to achieve the elastic swing of the spike segment 42, the proximal end of the spike segment 42 can be connected by an elastic element such as rubber and an open ring 41, or the spike segment 42 can be made elastic.

[0040] In one embodiment, in the wild, some animals with spatial memory and behavioral learning abilities can, upon encountering fixed anti-climb spikes, gradually find gaps without protection or take detours by memorizing the spikes' distribution patterns, thereby breaking through the protective barrier and causing the repelling effect of the fixed spikes to continuously decrease. Simultaneously, external debris such as fallen leaves, bird droppings, and soil tend to accumulate in the structural gaps of the fixed spikes, gradually filling and covering the effective protective area of ​​the spikes, reducing the physical blocking height and barrier effect of the spikes. Long-term use will significantly weaken or even eliminate the anti-climb repelling effect.

[0041] Based on this, a rotating column 33 is coaxially provided at both ends of the rotating shaft 3. The cross-sectional shape of the rotating column 33 is a regular polygon, such as a regular hexagon. Each rotating column 33 is fitted with a support knob 5. The support knob 5 is a two-stage concentric column structure. A fourth slot 51 is provided in the small end of the support knob 5. The shape of the fourth slot 51 matches the shape of the rotating column 33. During installation, it is interference-fitted onto the rotating column 33, so that the support knob 5 can rotate synchronously with the rotating column 33 and drive the rotating shaft 3 to move synchronously axially. The support knob 5 is rotatably mounted on the base 1. Specifically, the cross-sectional shape of the small end of the support knob 5 is circular. During installation, the small end of the support knob 5 is vertical and rotatably inserted into the side plate 12 of the base 1. The cross-sectional shape of the large end of the support knob 5 is a regular polygon, such as a regular hexagon, for easy screwing.

[0042] The rotating shaft 3 can move axially, and after moving, it forms a locked position and a released position. In the locked position, the rotating shaft 3 and the support member 2 form a circumferential constraint, and the two rotate synchronously, which makes it easy for the operator to stably adjust the posture and position of the spikes 4 and meet the control requirements for storage and deployment. In the released position, the circumferential constraint between the rotating shaft 3 and the support member 2 is released, and relative rotation can be achieved. Under the action of external forces such as wind or animal touch, the rotating shaft 3 can drive the spikes 4 to rotate autonomously, continuously changing the circumferential distribution position of the spikes 4, making it difficult for animals to form a fixed avoidance path through memory and learning, thus improving the long-term effectiveness of the deterrent protection. At the same time, the rotation can cause the spikes 4 to disturb the surrounding environment, preventing the accumulation of debris such as fallen leaves, bird droppings, and mud in the structural gaps of the spike section 42, achieving a self-cleaning effect, maintaining the effective blocking function of the spikes 4, and ensuring the continuous and stable protective performance.

[0043] In one embodiment, to enable the switching of the rotating shaft 3 between the locked and released positions, a third slot 22 is provided on the top of the support member 2. The third slot 22 is a strip-shaped structure, parallel to the support member 2, and has an arc-shaped cross-section. A row of first limiting grooves 221 is provided on both opposite sides of the third slot 22. The first limiting grooves 221 in the same row are arranged at intervals along the extension direction of the support member 2, and the first limiting grooves 221 in different rows are arranged correspondingly along the extension direction of the support member 2. A first limiting protrusion 222 is formed between adjacent first limiting grooves 221 in the same row. The rotating shaft 3 includes a main shaft portion 31 located at the center and a secondary shaft portion 32 located on the outer periphery and sleeved on the main shaft portion 31. The center of the main shaft portion 31 and the center of the secondary shaft portion 32 are on the same straight line but not concentric. (Refer to...) Figure 16 The center of the secondary shaft portion 32 is located above the center of the main shaft portion 31. The shape of the main shaft portion 31 matches the third slot 22 and is fitted into the third slot 22. Under the guidance of the third slot 22, the axial movement of the rotating shaft 3 can be realized, and the rotation of the rotating shaft 3 on the support member 2 can also be realized.

[0044] The cross-sectional shape of the secondary shaft portion 32 is fan-shaped. A row of second limiting grooves 322 is provided on both planar sidewalls of the secondary shaft portion 32. The second limiting grooves 322 in the same row are spaced apart along the axial direction of the secondary shaft portion 32, while different rows of second limiting grooves 322 are correspondingly arranged along the axial direction of the secondary shaft portion 32. A second limiting protrusion 323 is formed between adjacent second limiting grooves 322 in the same row. The cross-sectional portion of the secondary shaft portion 32 where the second limiting protrusion 323 is located and the cross-sectional portion of the third slot 22 where the first limiting protrusion 222 is located can abut. In the locked position, the first limiting... The positioning protrusion 222 and the second limiting protrusion 323 correspond and abut against each other, and the rotating shaft 3 and the support member 2 rotate synchronously to facilitate the adjustment of the position of the spike 4. In the release position, the first limiting protrusion 222 and the second limiting groove 322 are correspondingly set, and the second limiting protrusion 323 and the first limiting groove 221 are correspondingly set. The groove depths of the first limiting groove 221 and the second limiting groove 322 are both limited, so that the rotating shaft 3 can rotate relative to the support member 2 at a certain angle, so that the spike section 42 can be driven to rotate by the rotating shaft 3 when subjected to external forces (such as wind force / animal contact, etc.).

[0045] More specifically, the mounting groove 321 is provided on the secondary shaft portion 32 and corresponds to the second limiting protrusion 323.

[0046] In a further embodiment, the arc of the third slot 22 is a superior arc, so that when the spindle portion 31 and the third slot 22 are engaged, the angle of circumferential coverage is greater than 180 degrees, which helps to improve installation stability.

[0047] In one embodiment, in the wild, the distribution of animal species and the frequency of their activities vary significantly with seasonal and annual changes, and the corresponding anti-climb protection needs and risk levels also change dynamically. The protective form and intensity of traditional fixed spike structures cannot be adjusted once installed, making it difficult to match the real-time changing animal risk levels on-site. This may result in redundant protection during low-risk periods or insufficient protection during high-risk periods, failing to achieve long-term anti-climb protection that is both adaptable and targeted.

[0048] Based on this, multiple limiting holes 121 are provided at the contact position between the base 1 and the support knob 5. The limiting holes 121 are specifically vertically provided on the surface of the side plate 12 and are circular in shape. The multiple limiting holes 121 are arranged in a direction perpendicular to the axis of the rotation shaft 3, and the distance between the centers of two adjacent limiting holes 121 is greater than their radius but less than their diameter, ensuring that two adjacent limiting holes 121 partially overlap, thereby allowing the support knob 5 to form multiple movable points. The straight line where the centers of the multiple limiting holes 121 are located is perpendicular to the surface of the base plate 11, so that when the movable point of the support knob 5 is changed, the distance between the rotation shaft 3 and the base 1 can be changed, thereby allowing the length of the spiked segment 42 that can be accommodated between them to be adapted to the types of animals that actually need protection on site, thereby achieving targeted protection.

[0049] In one embodiment, the arc shape of the mounting groove 321 and the opening ring 41 are both superior arcs, so that when the two are matched, the angle of their circumferential coverage is greater than 180 degrees, which helps to improve installation stability.

[0050] In one embodiment, the open ring 41 is made of an elastically deformable material, such as plastic, and its diameter is slightly smaller than that of the mounting groove 321. During installation, by manually bending both ends of the open ring 41, its opening angle is increased to facilitate insertion into the mounting groove 321, while also causing it to elastically deform. After the open ring 41 is inserted into the mounting groove 321, the open ring 41 elastically returns to its original position, thereby increasing its clamping force on the rotating shaft 3 and improving installation stability.

[0051] In other embodiments, to improve installation stability, the spikes 4 can also be fixed to the rotating shaft 3 by applying glue or by spot welding after assembly.

[0052] In one embodiment, to improve applicability, an elastic deformation layer, such as rubber, is provided at the bottom of the base 1 to adapt to different mounting surfaces.

[0053] In one embodiment, to facilitate the rotation of the support member 2, a lever 23 is provided at the top end of the support member 2, and the lever 23 and the third slot 22 are arranged circumferentially; in use, the operator can rotate the support member 2 by levering the lever 23.

[0054] In one embodiment, to improve applicability, multiple driving units are configured, which are connected side-by-side circumferentially to form a ring structure fitted onto the power equipment pole. This allows for adaptation to various mounting surfaces, improving applicability; furthermore, when a driving unit is damaged, the damaged unit can be replaced individually, thus improving maintenance convenience and avoiding the resource waste of replacing the entire unit.

[0055] Specifically, the multiple driving-off units can be categorized by model into intermediate type, basic type, right-angle type, connecting type, and circumferential type. The intermediate type has the same basic structure as the aforementioned driving-off units, the difference being that its side plate 12 is rectangular. Figure 5 At both ends of the L-shaped rod 6. The basic structure of the basic model is the same as that of the aforementioned driving unit, except that its side plate 12 is rectangular in shape, and a male hinge joint 15 is provided on the top of one side wall of each side plate 12, and a female hinge joint 16 is provided on the top of the other opposite side wall. The male hinge joint 15 and the female hinge joint 16 are located on both sides of the limiting hole 121, respectively.

Figure 9 Conversely, the male hinge joint 15 and the female hinge joint 16 are respectively located at both ends of the short bottom edge of its side plate 12, with the male hinge joint 15 located at the junction of the short bottom edge and the hypotenuse, and the female hinge joint 16 located at the junction of the short bottom edge and the right-angled side; for example Figure 12 As shown, the difference in the fourth right-angle model is that its side plate 12 is shaped like a right-angled trapezoid, and... Figure 11 In a mirror configuration, the male hinge joint 15 and the female hinge joint 16 are respectively located at both ends of the short bottom edge of its side plate 12, with the male hinge joint 15 located at the junction of the short bottom edge and the right-angled side, and the female hinge joint 16 located at the junction of the short bottom edge and the inclined side.

[0057] like Figure 13 As shown, the connection model includes a base 9, which is a strip structure with a cross-sectional shape consisting of five straight sides and one curved side. The five straight sides are divided into three horizontal sides and two vertical sides according to the horizontal and vertical directions. The five straight sides are along... Figure 13 From left to right, the three horizontal edges are: horizontal edge, vertical edge, horizontal edge, vertical edge, and horizontal edge. The heights of the three horizontal edges in the vertical direction are low, high, and medium, respectively. The arc edge protrudes downward, and its two ends are connected to the two outermost horizontal edges that are far apart from each other. Multiple spike segments 42 are arranged circumferentially along the arc edge.

[0058] like Figure 14As shown, the basic structure of the circumferential model is the same as that of the aforementioned driving unit. The difference is that its side plate 12 is rectangular in shape, and a male hinge joint 15 is provided at the bottom of one side wall of each side plate 12, and a female hinge joint 16 is provided at the bottom of the other opposite side wall. The male hinge joint 15 and the female hinge joint 16 are located on both sides of the limiting hole 121.

[0059] When the pole used for the animal deterrent device in the electrical equipment is an L-shaped pole (6), i.e., angle steel, it can be used as follows: Figure 5 and Figure 6 There are two connection methods.

[0060] Specifically, such as Figure 5 As shown, the animal herders of the power equipment share intermediate models, basic models, and right-angle models. The basic model is located at the straight section of the L-shaped rod 6, with adjacent basic models hinged together via male hinge joint 15 and female hinge joint 16. The outer corners of the L-shaped rod 6 feature a first type of right-angle model and a second type of right-angle model with overlapping bevels. The first and second right-angle models are hinged together via male hinge joint 15 and female hinge joint 16. Furthermore, the first and second right-angle models are respectively connected via male hinge joint 15 and female hinge joint 16. 16. A hinged connection is achieved between the L-shaped rod body 6 and the adjacent base model; the inner corner of the L-shaped rod body 6 is the third and fourth right-angle model with overlapping waists. The third and fourth right-angle models are hingedly connected through male hinge joint 15 and female hinge joint 16. The third and fourth right-angle models are also hingedly connected to the adjacent base model through male hinge joint 15 and female hinge joint 16 respectively; the intermediate transformation model is located at both ends of the L-shaped rod body 6, and it can be connected to the adjacent base model by adhesive bonding.

[0061] like Figure 6 As shown, the animal deterrent mechanism of the power equipment uses a basic model, a right-angle model, and a connecting model, and their positional distribution is basically the same as described above. The difference is that the intermediate model is replaced by the connecting model, and it can achieve stable contact with the adjacent basic unit by using an interference fit. The special shape of the base 9 of the connecting model allows it to completely fill the gap between the end of the L-shaped rod 6 and the gap between two adjacent basic units, ensuring a stable connection.

[0062] When the pole used for the animal deterrent device in the electrical equipment is a square pole 7, it can be adopted as follows: Figure 7 The connection method shown.

[0063] Specifically, such as Figure 7As shown, the animal herder of the power equipment uses both a basic model and a right-angle model. The basic model is located at the straight section of the square pole 7, and adjacent basic models are hinged together by a male hinge joint 15 and a female hinge joint 16. At the corners of the square pole 7, there are two right-angle models with overlapping sloping sides. The first right-angle model and the second right-angle model are hinged together by a male hinge joint 15 and a female hinge joint 16. The first right-angle model and the second right-angle model are also hinged together with adjacent basic models by male hinge joint 15 and female hinge joint 16, respectively.

[0064] When the pole of the electric equipment used for the animal deterrent device is a circular pole 8, it can be adopted as follows: Figure 8 The connection method shown.

[0065] Specifically, such as Figure 8 As shown, the animal herder of the power equipment requires the use of circumferential models. Multiple circumferential models are arranged circumferentially, and adjacent circumferential models are hinged together by male hinge joint 15 and female hinge joint 16.

[0066] In a further embodiment, to improve the stability of the ring structure formed by connecting multiple driving units side by side in the circumferential direction when it is fitted onto the pole of the power equipment, the ring structure formed by connecting multiple driving units side by side in the circumferential direction can be fixed from the outside by fasteners such as cable ties and clamps.

[0067] In other embodiments, to improve the stability of the ring structure formed by multiple driving units connected side by side in the circumferential direction when it is fitted onto the pole of the power equipment, a through hole 112 is provided vertically on the side wall of the base plate 11 and the guide wedge 14 on the same side. Fasteners such as cable ties and clamps can be used to fix the ring structure formed by multiple driving units connected side by side in the circumferential direction from the inside through the through hole 112.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
