Description

Technical Field

[0001] This invention relates to the field of bird deterrent equipment technology, specifically to a direct-fall bird deterrent and its deployment device. Background Technology

[0002] Currently, in order to prevent and control bird damage to power distribution networks and reduce accidents such as line network failures and short circuits caused by bird droppings, bird nests, bird flight, and bird pecking, it is usually necessary to install bird deterrents on power equipment to drive away birds and ensure the normal operation of power equipment. Due to the large number and density of power distribution network lines, it is not possible to install bird deterrents on all transmission lines according to the design requirements. Intervention is only carried out when birds are found to be nesting, and the fault is passively eliminated by energizing or de-energizing the power.

[0003] In existing technologies, when installing bird deterrents, workers need to use high-altitude work equipment to climb to the power equipment to install the bird deterrents. This requires workers to climb the tower and then install the bird deterrents onto the tower pole or tower body, which increases the difficulty of operation for workers, reduces installation efficiency, and increases the risk of workers falling from heights and being electrocuted.

[0004] Conventional drones are not suitable for carrying traditional bird deterrents, so a direct-fall bird deterrent and its delivery device are proposed to solve the above-mentioned problems.

[0005] For example, the patent document "A Method for Installing a Bird Repellent on a Low-Altitude Power Line Using a Bird Repellent Installation Device," published in Chinese patent literature (publication number CN105552783B), includes the following steps: A. Placing the U-shaped base of the bird repeller in the positioning groove; B. Rotating the bolt on the U-shaped base of the bird repeller in the reverse direction until the bolt head is embedded in the groove of the bolt head clip; C. Carrying the bird repeller installation device, climbing the utility pole to below the crossarm; D. Holding the insulating rod, securing the U-shaped base of the bird repeller to the crossarm; E. Raising the lifting unit while simultaneously rotating the tightening unit clockwise, tightening the bolt on the U-shaped base of the bird repeller onto the crossarm, thus completing the bird repeller installation; F. Lowering the lifting unit and then separating the housing from the U-shaped base of the bird repeller using the insulating rod; G. The worker leaves the utility pole. The drawback of this patent is that it requires operators to climb the utility pole to install the bird repeller, resulting in high labor costs, low efficiency, and safety hazards. Summary of the Invention

[0006] The present invention aims to overcome the problems of high cost, low efficiency and safety hazards in the installation of bird deterrents by manual methods in the prior art. It provides a direct-drop bird deterrent and its delivery device, which can remotely deliver the bird deterrent by drone, eliminating the need for high-altitude climbing and operation, thus achieving high installation efficiency and avoiding safety issues for operators.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This invention discloses a direct-fall bird deterrent, comprising a main column, the main column including a partition; a movable block disposed outside the partition, including a mounting cylinder with a latch on its side; a main spring disposed between the movable block and the partition; a hinge block disposed outside the mounting cylinder via a bearing; and a force-bearing arm hinged to the hinge block via a hinge shaft, the hinge shaft having a torsion spring on its exterior. The force-bearing arm has a buckle passing through the latch, and a bird deterrent structure is also mounted on the force-bearing arm.

[0008] In this application, when the bird deterrent device is deployed by a drone, the inertia generated by gravity will cause the movable block and the main column to undergo vertical relative displacement. This displacement is then caused by the partition pressing the buckle at the latch, which causes the force arm to automatically unfold outside the main column under the action of the torsion spring, thereby automatically completing the installation.

[0009] Preferably, the main column includes a counterweight base, a vertical rod, and a top block arranged sequentially from bottom to top. The bottom end of the counterweight base is provided with a strong magnet, the top end of the top block has an arc-shaped surface, and the top block and the partition are connected to each other by threads.

[0010] Preferably, the outer ring of the counterweight base is provided with a fixing groove, and the side of the fixing groove near the upright is an arc-shaped groove surface or an inclined groove surface.

[0011] Preferably, the movable block includes two half-shells connected to each other by screws. Each half-shell has a mounting groove on its opposite side, and a mounting cylinder is provided at the top of each half-shell. The outside of the mounting cylinder is connected to the hinge block by a bearing.

[0012] Preferably, the bayonet is located on the outer surface of the semi-shell, and the bayonet is in communication with the mounting groove.

[0013] Preferably, the hinge block includes a hinge body, and a plurality of hinge seats are provided on the outside of the hinge body. The plurality of hinge seats are distributed circumferentially at equal intervals, and a threaded hole is provided on one side surface of the hinge seat.

[0014] Preferably, the hinge arm is provided with a buckle on the side near the movable block, and the buckle has an inclined surface on its lower side that is opposite to the partition. The bottom end of the hinge arm is provided with a force plate and two whistles from top to bottom. Reflectors are provided on both sides of the force plate, and the two whistles face opposite directions.

[0015] A drop-type bird deterrent device is provided for deploying the aforementioned drop-type bird deterrent. It includes a deployment cylinder and further comprises: a power mechanism disposed inside the deployment cylinder, comprising an electric push rod and a pushing component; a movable groove disposed on the deployment cylinder, the length of which is radially aligned with the deployment cylinder, the movable groove communicating with the interior of the deployment cylinder through a fixed opening; a fixed block disposed at the opening; and a fixed ring mounted outside the movable groove, the fixed block being connected to the fixed ring via a pressure spring.

[0016] Preferably, the dispensing cylinder includes a first cylinder body, the interior of which is provided with an upper hole and a lower hole, the diameter of the lower hole being larger than the diameter of the upper hole, and the pushing member includes a first pusher head.

[0017] Preferably, the delivery cylinder includes a second cylinder body, the interior of which is provided with a frustum-shaped hole, the lower inner diameter of which is larger than the upper inner diameter, and the pushing member includes a second pusher head, the bottom end of which is provided with a thrust block.

[0018] Therefore, the present invention has the following beneficial effects: (1) The present invention sets up components such as a delivery tube, a fixed block, a pressure spring and a power mechanism. Through the cooperation between the pressure spring and the fixed block, the main column is fixed inside the delivery tube, and the power mechanism works to drive the bird repeller and the delivery tube to generate relative movement, thereby causing the counterweight base and the fixed block to squeeze each other. After squeezing, the fixed block moves laterally under the action of the lateral component force, so that the bird repeller and the delivery tube are separated; (2) By setting up the bird repeller, the drone is made easy to carry. By setting up the first tube, the second tube, the first push head and the second push head, the bird repeller is deployed in different ways. The first tube and the second push head cooperate with each other, making the bird repeller more suitable for close-range deployment. The second tube and the first push head cooperate with each other, making the bird repeller more suitable for long-range deployment. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: As Figure 1-6 As shown in Figures 8-13, a direct-fall bird repeller and its deployment device comprise two parts: a direct-fall bird repeller and a direct-fall bird repeller deployment device. The direct-fall bird repeller deployment device is as follows: Figure 15 The image shows the installation on the UAV 99.

[0023] The drop-type bird deterrent includes a main column 3, a movable block 6, a main spring 8, a hinge block 7, and a force-bearing arm 9.

[0024] The main column 3 includes a counterweight base 31, a fixing groove 32, an upright 33, a partition 34, a top block 35, and a strong magnet 36. The top of the counterweight base 31, from bottom to top, is provided with the upright 33, partition 34, and top block 35. The bottom of the counterweight base 31 is provided with the strong magnet 36. The top of the top block 35 has an arc-shaped surface. The top block 35 and the partition 34 are connected to each other by threads. The outer ring of the counterweight base 31 is provided with a fixing groove 32, the side of the fixing groove 32 near the upright 33 being an arc-shaped groove surface or a sloping groove surface. The counterweight base 31 is used to increase the weight of the bottom of the direct-fall bird repeller, thereby lowering its center of gravity and ensuring that the direct-fall bird repeller can fall vertically. The strong magnet allows the counterweight base to be directly attached to the tower body. The fixing groove 32 is used to cooperate with the direct-fall bird repeller deployment device to form a fixed position. The upper outer side of the partition 34 is provided with an inclined surface for pushing the movable block 6 upward, and the top block 35 is used to cooperate with the drop-type bird deterrent device to achieve movement.

[0025] The movable block 6 is disposed outside the partition 34 and includes a mounting cylinder 63 and a bayonet 64. The movable block 6 includes a half-shell 61, which is connected to each other by screws. Each half-shell 61 has a mounting groove 62 on opposite sides. The top of the half-shell 61 is provided with a mounting cylinder 63. The outside of the mounting cylinder 63 is provided with a hinge block 7 through a bearing. The outer surface of the half-shell 61 is provided with a bayonet 64, which communicates with the mounting groove 62.

[0026] The main spring 8 is disposed between the movable block 6 and the partition plate 34. The main spring 8 is coaxially disposed with the main column 3, so that the movable block 6 and the partition plate 34 can move vertically relative to each other.

[0027] The movable block 6 is located outside the main column 3. The counterweight base 31 makes the bird repeller's center of gravity low, ensuring that the bird repeller remains vertical when it is dropped from a high position. The strong magnet 36 allows the bird repeller to be fixed to the outer surface of the power equipment or tower by magnetic attraction. The main spring 8 provides support for the movable block 6. The movable block 6 can move relative to the main column 3, and the movement compresses the main spring 8 to generate elastic force.

[0028] The hinge block 7 is mounted on the outside of the mounting cylinder 63 via bearings. The hinge block 7 includes a hinge body 71, and hinge seats 72 are provided on the outside of the hinge body 71. The hinge seats 72 are distributed in a ring at equal intervals. A threaded hole 73 is provided on one side surface of the hinge seat 72 for fixing the force-bearing arm 9 to the hinge seat 72. In this embodiment, there are four hinge seats 72, and correspondingly, there are also four force-bearing arms 9.

[0029] The force-bearing arm 9 is hinged to the hinge block 7 via the hinge shaft 11, and includes a hinge arm 91, a buckle 92, a force-bearing plate 93, a reflector 94, and a whistle 95. The hook 92 is provided on the side of the hinge arm 91 near the movable block 6, and the bottom end of the hook 92 is an inclined surface. The bottom end of the hinge arm 91 is provided with a force-bearing plate 93 and two whistles 95 from top to bottom. Reflectors 94 are provided on both sides of the force-bearing plate 93, and the two whistles 95 face opposite directions.

[0030] The drop-type bird deterrent device includes: a dropping cylinder 1, a power mechanism 10, a movable groove 13, a fixing block 5, and a fixing ring 2.

[0031] The delivery cylinder 1 includes a first cylinder 111, which has an upper hole and a lower hole inside. Both the upper hole and the lower hole are straight holes, and the diameter of the lower hole is larger than that of the upper hole. The upper part of the main column 3 of the direct-fall bird deterrent is located in the upper hole, and the counterweight base of the main column 3 is located in the lower hole.

[0032] The power mechanism 10 is located inside the delivery cylinder 1, and includes an electric push rod 101 and a pusher, the pusher including a first push head 102. The electric push rod enables the pusher and the first push head 102 to move the drop-type bird deterrent downwards.

[0033] The movable groove 13 is provided on the dispensing cylinder 1, and its length direction is the radial direction of the dispensing cylinder 1. The movable groove 13 is connected to the inside of the dispensing cylinder through a fixed opening. Specifically, the fixed opening is connected to the lower hole of the first cylinder 111.

[0034] The fixing ring 2 is screwed to the outside of the dispensing cylinder 1. The fixing ring is also located outside the movable groove and covers the movable groove.

[0035] The fixing block 5 is located inside the movable groove 13 and at the fixing opening. The fixing block 5 is connected to the fixing ring 2 by the pressure spring 4. The fixing block 5 extends to one side of the fixing groove 32 with an arc-shaped end face, and the arc-shaped end face is located in the fixing groove of the counterweight base 31.

[0036] The first cylinder 111, the fixing block 5, and the pressure spring 4 work together to fix the bird deterrent. At this time, the bird deterrent is fixed inside the first cylinder 111, and the fixing block 5 is inserted into the fixing groove 32 under the action of the pressure spring 4.

[0037] The first pusher 102 and the first cylinder 111 cooperate with each other, so that when the device is at a position that is far from the vertical distance of the tower, the first pusher 102 can be pushed by the electric push rod 101 to move. The first pusher 102 pushes the main column 3 to move downward. During this process, the main block 3 squeezes the fixed block 5 and then disengages. When the bird deterrent falls to the surface of the tower, it is accelerated. When the main column 3 collides with the tower, the movable block 6 continues to move downward under the action of inertia, which in turn drives the force arm 9 to move towards the partition 34. At this time, the buckle 92 undergoes elastic deformation after being squeezed by the partition 34, which causes the buckle 92 to separate from the buckle 64. After separation, the restriction on the force arm 9 is eliminated, and it unfolds under the action of the torsion spring 12. The unfolded force arm 9 is placed horizontally.

[0038] In practical use, the first cylinder 111 and the electric push rod 101 are mounted on the bottom of the drone using screws. At this time, the first cylinder 111 and the first push head 102 cooperate with each other. When the bird deterrent is placed in the first cylinder 111, the bird deterrent's state is as follows: Figure 3 As shown, the force arm 9 is in the retracted state.

[0039] When deployment is required, the drone carrying the bird deterrent can be controlled to fly to the top of the tower. By controlling the electric push rod 101 to work, the first push head 102 is driven to press down on the main column 3. After the main column 3 is pressed, it drives the counterweight base 31 to move together. At this time, the counterweight base 31 presses the fixing block 5. Since the contact surfaces of the fixing block 5 and the fixing groove 32 are both arc surfaces, there is a lateral component of the interaction force, which causes the fixing block 5 to move away from the counterweight base 31, so that the fixing block 5 separates from the fixing groove 32. After separation, the bird deterrent falls out of the inside of the second cylinder 113 under the action of gravity. During the falling process, the fixing block 5 is reset by the left and right sides of the pressure spring 4.

[0040] Before the bird repeller contacts the tower, the lever arm 9 is still in the retracted state. At this time, due to the counterweight base 31, the bird repeller's center of gravity is low, thus ensuring that the counterweight base 31 remains at the bottom during the fall. Figure 2 When the bird deterrent device collides with the tower body, that is, when the counterweight base 31 comes into contact with the tower body, the counterweight base 31 is obstructed and cannot continue to move downward. Under the action of inertia, the movable block 6 drives the hinge block 7 and the force arm 9 to continue to move downward. During this process, the buckle 92 comes into contact with and is squeezed by the partition 34, causing the buckle 92 to deform and then disengage from the buckle 64. After disengagement, the force arm 9 unfolds under the action of the torsion spring 12 and is in a horizontal state.

[0041] During the movement of the movable block 6, the main spring 8 is compressed by force. When the movable block 6 stops moving due to inertia, it returns to its original position under the action of elasticity. After several reciprocating movements, the position of the movable block 6 tends to be constant, at which point bird deterrence operations can be carried out.

[0042] The bird deterrent is attached to the tower by a strong magnet 36. When the load-bearing plate 93 is pushed by the wind, the entire load-bearing arm 9 rotates around the bearing. During this rotation, the reflector 94 and the whistle 95 move in a circular motion. In this process, the reflector 94 reflects sunlight, thus initially deterring birds through sunlight. As the whistle 95 rotates, airflow enters the whistle 95 and produces a sharp sound, thus deterring birds a second time. It drives away birds by reflecting sunlight and producing a sharp sound. Since the two whistles 95 on the same load-bearing plate face opposite directions, they can sound under different wind directions.

[0043] Compared to traditional bird repellers, this bird repeller features a retractable support arm 9, reducing the space required for placement and making it easier for drones to carry. With its matching delivery device, the bird repeller can be deployed from above the tower. During deployment, the support arm 9 remains in an indeterminate state, minimizing the impact of airflow on the bird repeller and ensuring high deployment accuracy. Utilizing gravity and inertia, the indeterminate support arm 9 automatically deploys upon contact with the tower, ensuring accurate deployment and enabling normal operation of the bird repeller after deployment.

[0044] Example 2: Figure 1-5 As shown in Figures 7-12 and 14, a direct-fall bird repeller and its deployment device comprise two parts: a direct-fall bird repeller and a direct-fall bird repeller deployment device. The direct-fall bird repeller deployment device is as follows: Figure 15 The image shows the installation on the UAV 99.

[0045] The drop-type bird deterrent includes a main column 3, a movable block 6, a main spring 8, a hinge block 7, and a force-bearing arm 9.

[0046] The main column 3 includes a counterweight base 31, a fixing groove 32, an upright 33, a partition 34, a top block 35, and a strong magnet 36. The top of the counterweight base 31, from bottom to top, is provided with the upright 33, partition 34, and top block 35. The bottom of the counterweight base 31 is provided with the strong magnet 36. The top of the top block 35 has an arc-shaped surface. The top block 35 and the partition 34 are connected to each other by threads. The outer ring of the counterweight base 31 is provided with a fixing groove 32, the side of the fixing groove 32 near the upright 33 being an arc-shaped groove surface or a sloping groove surface. The counterweight base 31 is used to increase the weight of the bottom of the direct-fall bird repeller, thereby lowering its center of gravity and ensuring that the direct-fall bird repeller can fall vertically. The strong magnet allows the counterweight base to be directly attached to the tower body. The fixing groove 32 is used to cooperate with the direct-fall bird repeller deployment device to form a fixed position. The upper outer side of the partition 34 is provided with an inclined surface for pushing the movable block 6 upward, and the top block 35 is used to cooperate with the drop-type bird deterrent device to achieve movement.

[0047] The movable block 6 is disposed outside the partition 34 and includes a mounting cylinder 63 and a bayonet 64. The movable block 6 includes a half-shell 61, which is connected to each other by screws. Each half-shell 61 has a mounting groove 62 on opposite sides. The top of the half-shell 61 is provided with a mounting cylinder 63. The outside of the mounting cylinder 63 is provided with a hinge block 7 through a bearing. The outer surface of the half-shell 61 is provided with a bayonet 64, which communicates with the mounting groove 62.

[0048] The main spring 8 is disposed between the movable block 6 and the partition plate 34. The main spring 8 is coaxially disposed with the main column 3, so that the movable block 6 and the partition plate 34 can move vertically relative to each other.

[0049] The movable block 6 is located outside the main column 3. The counterweight base 31 makes the bird repeller's center of gravity low, ensuring that the bird repeller remains vertical when it is dropped from a high position. The strong magnet 36 allows the bird repeller to be fixed to the outer surface of the power equipment or tower by magnetic attraction. The main spring 8 provides support for the movable block 6. The movable block 6 can move relative to the main column 3, and the movement compresses the main spring 8 to generate elastic force.

[0050] The hinge block 7 is mounted on the outside of the mounting cylinder 63 via bearings. The hinge block 7 includes a hinge body 71, and hinge seats 72 are provided on the outside of the hinge body 71. The hinge seats 72 are distributed in a ring at equal intervals. A threaded hole 73 is provided on one side surface of the hinge seat 72 for fixing the force-bearing arm 9 to the hinge seat 72. In this embodiment, there are four hinge seats 72, and correspondingly, there are also four force-bearing arms 9.

[0051] The force-bearing arm 9 is hinged to the hinge block 7 via the hinge shaft 11, and includes a hinge arm 91, a buckle 92, a force-bearing plate 93, a reflector 94, and a whistle 95. The hook 92 is provided on the side of the hinge arm 91 near the movable block 6, and the bottom end of the hook 92 is an inclined surface. The bottom end of the hinge arm 91 is provided with a force-bearing plate 93 and two whistles 95 from top to bottom. Reflectors 94 are provided on both sides of the force-bearing plate 93, and the two whistles 95 face opposite directions.

[0052] The drop-type bird deterrent device includes: a dropping cylinder 1, a power mechanism 10, a movable groove 13, a fixing block 5, and a fixing ring 2.

[0053] The dispensing cylinder 1 includes a second cylinder 113. The upper part of the interior of the second cylinder 113 is a straight hole, and the lower part is provided with a frustum hole 112. The lower inner diameter of the frustum hole is larger than the upper inner diameter.

[0054] The power mechanism 10 is located inside the delivery cylinder 1 and includes an electric push rod 101 and a pusher. The pusher includes a second push head 103, and a push block 104 is provided at the bottom end of the second push head 103. The electric push rod 101 can cause the pusher and the second push head 103 to drive the direct-fall bird deterrent device downward.

[0055] The movable groove 13 is provided on the dispensing cylinder 1, and its length direction is the radial direction of the dispensing cylinder 1. The movable groove 13 is connected to the inside of the dispensing cylinder through a fixed opening. Specifically, the fixed opening is connected to the frustum hole 112 of the second cylinder 113.

[0056] The fixing ring 2 is screwed to the outside of the dispensing cylinder 1. The fixing ring 2 is also located outside the movable groove and covers the movable groove.

[0057] The fixing block 5 is located inside the movable groove 13 and at the fixing opening. The fixing block 5 is connected to the fixing ring 2 by the pressure spring 4. The fixing block 5 extends to one side of the fixing groove 32 with an arc-shaped end face, and the arc-shaped end face is located in the fixing groove of the counterweight base 31.

[0058] The second cylinder 113, the fixing block 5, and the pressure spring 4 work together to fix the bird deterrent. At this time, the bird deterrent is fixed inside the second cylinder 113, and the fixing block 5 is inserted into the fixing groove 32 under the action of the pressure spring 4.

[0059] The second pusher 103 and the second cylinder 113 cooperate with each other, so that when the device is at a relatively large vertical distance from the tower, the electric push rod 101 can push the second pusher 103 and the push block 104 to move. The push block 104 pushes the main column 3 downward. During this process, the main spring 8 is compressed. When the main spring 8 is compressed to a certain extent, the main column 3 receives sufficient elastic force, and the counterweight base 31 presses the fixing block 5, causing the fixing block 5 to separate from the fixing groove 32, thus realizing the separation of the bird repeller from the second cylinder 113. During the movement of the movable block 6, the buckle 92 moves towards the partition 34 and is squeezed. After the buckle 92 and the partition 34 are squeezed together, they deform, which causes the buckle 92 to separate from the latch 64. After separation, the force arm 9 is unfolded by the elastic force of the torsion spring 12. When unfolded, the force arm 9 is restricted by the frustum hole 112, which limits the extent of unfolding. On the other hand, the interaction force generated between the force arm 9 and the frustum hole 112 has a vertical component, which allows the bird deterrent to detach from the drone more quickly.

[0060] After detachment, the restriction on the force arm 9 is completely eliminated, and it fully unfolds under the action of the torsion spring 12, with the unfolded force arm 9 placed horizontally.

[0061] During the movement of the movable block 6, the main spring 8 is compressed by force. When the movable block 6 stops moving due to inertia, it returns to its original position under the action of elasticity. After several reciprocating movements, the position of the movable block 6 tends to be constant, at which point bird deterrence operations can be carried out.

[0062] The bird deterrent is attached to the tower by a strong magnet 36. When the load-bearing plate 93 is pushed by the wind, the entire load-bearing arm 9 rotates around the bearing. During this rotation, the reflector 94 and the whistle 95 move in a circular motion. In this process, the reflector 94 reflects sunlight, thus initially deterring birds through sunlight. As the whistle 95 rotates, airflow enters the whistle 95 and produces a sharp sound, thus deterring birds a second time. It drives away birds by reflecting sunlight and producing a sharp sound. Since the two whistles 95 on the same load-bearing plate face opposite directions, they can sound under different wind directions.

[0063] Compared to traditional bird repellers, this bird repeller features a retractable support arm 9, reducing the space required for placement and making it easier for drones to carry. With its matching delivery device, the bird repeller can be deployed from above the tower. During deployment, the support arm 9 remains in an indeterminate state, minimizing the impact of airflow on the bird repeller and ensuring high deployment accuracy. Utilizing gravity and inertia, the indeterminate support arm 9 automatically deploys upon contact with the tower, ensuring accurate deployment and enabling normal operation of the bird repeller after deployment.
