Description

Technical Field

[0001] This invention relates to the field of power equipment protection technology, and in particular to a bird deterrent device for power transmission lines. Background Technology

[0002] The safe and stable operation of transmission lines is the core guarantee for reliable power supply of the power system. Bird activity has become one of the main sources of risk to line safety. When birds build nests at insulators, crossarms and conductor connections of transmission lines, nesting materials such as dry grass and branches can easily cause short circuits in the lines. Bird droppings attached to the surface of insulators can reduce their insulation performance and lead to flashover tripping accidents, bringing huge economic costs and safety pressure to power operation and maintenance.

[0003] Existing bird deterrent devices for power transmission lines rely on wind power to rotate a wind cup, which contains a reflector that reflects light to deter birds. However, when these devices are exposed to air for extended periods, dust easily accumulates on the reflector surface, reducing its reflectivity and thus affecting its bird deterrent effect. Furthermore, relying solely on wind cup rotation and light reflection makes the bird deterrent method rather simplistic and impractical. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a bird deterrent device for power transmission lines that can deter birds through sound, light, and simulated bird flight during use, and also achieves a self-cleaning function, thereby improving the bird deterrent effect and efficiency.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A bird deterrent device for power transmission lines includes a base with an inverted U-shaped structure. Locking mechanisms are symmetrically arranged on the lower sides of the base. A support shaft is mounted on the top of the base, and a bushing is rotatably connected to the outer side of the support shaft. Multiple drive mechanisms are circumferentially distributed above the outer side of the bushing. Each drive mechanism includes a support rod, a wind cup, and a reflector. A wind groove is formed in the middle of the back end of the wind cup, and a cleaning mechanism is provided inside the wind cup at the back end of the reflector. A housing is connected to the middle of the outer side of the bushing via a bearing, and a transmission mechanism is provided inside the housing.

[0006] Preferably, the cleaning mechanism includes a main shaft fixed inside the air cup, the main shaft having a U-shaped structure, and a support plate rotatably connected to the middle of the main shaft, the support plate being eccentrically disposed on the outside of the main shaft, an impact plate being installed at the top of the support plate, the impact plate having arc-shaped structures at both ends, and the impact plate being asymmetrically fixed at the top of the support plate, and magnetic plates being installed on opposite sides of the support plate and the air cup, and the two sets of magnetic plates being of the same polarity.

[0007] Preferably, the transmission mechanism includes a main gear located inside the housing, the main gear being fixedly connected to the bushing, a secondary gear meshing with the outer side of the main gear, the included angle between the main gear and the secondary gear being 90°, a connecting shaft fixed in the middle of the secondary gear, an eccentric block fixed on the connecting shaft at the end away from the secondary gear, a base plate provided above the eccentric block, and two sets of fins abutting at the top of the base plate, a main frame provided on the outer side of the fins, and the fins being rotatably connected to the main frame.

[0008] Preferably, the locking mechanism includes a locking bolt connected to the base, one end of the locking bolt is connected to a locking plate via a bearing, and a rubber pad is fixed to the end of the locking plate away from the locking bolt.

[0009] Preferably, the wind cup has a polygonal hemispherical structure, and the surface of the wind cup is made of aluminum-plated reflective film material.

[0010] Preferably, a transmission gear is installed on the lower outer side of the bushing, and an elastic frame is provided on the outer side of the transmission gear.

[0011] Preferably, the elastic frame includes multiple sets of mounting rods fixed circumferentially on the base, and each set of mounting rods has an elastic metal sheet fixed to its outer side, the elastic metal sheet being located at the same horizontal position as the transmission gear.

[0012] Preferably, a wind whistle is installed on the outer side of the support rod, and the air intake end of the wind whistle is positioned opposite to the rotation angle of the drive mechanism.

[0013] Preferably, the base plate is slidably connected to the main frame, and the main frame is provided with a sliding groove adapted to the base plate, and the main frame is installed at the back end of the chassis.

[0014] Preferably, a locking nut is installed on the base corresponding to the locking bolt.

[0015] By adopting the above technical solution, the present invention has the following advantages: 1. By setting up a cleaning mechanism and a wind duct, the wind cup inside the mechanism can be driven to rotate. During this process, the wind enters the wind cup from the wind duct and blows towards the impact plate inside the cleaning mechanism. The impact plate is affected by the wind force, which drives the support plate to rotate along the main shaft, so that the impact plate comes into contact with the reflector. The vibration generated after the reflector comes into contact with the impact plate will cause the dust adhering to its surface to fall off, thereby achieving self-cleaning. This prevents dust from blocking the reflector and reducing its reflectivity, thus improving the bird-repelling effect. After the impact plate comes into contact with the reflector, the two sets of magnetic plates move closer to each other. Since the two sets of magnetic plates are of the same polarity, the like poles repel each other, which will cause the support plate to move the impact plate away from the reflector, thus causing the impact plate to swing.

[0016] 2. By setting up a transmission mechanism, the main gear rotates during the rotation of the bushing, and the main gear drives the connecting shaft to rotate through the secondary gear. The connecting shaft can then drive the eccentric block to rotate. The rotation of the eccentric block will push the base plate upward. At this time, the base plate pushes one end of the wing plate upward and makes the wing plate rotate along the main frame. The wing plate simulates the flapping effect of bird wings, thereby performing bird deterrence.

[0017] 3. By setting up a transmission gear and an elastic frame, the bushing can drive the transmission gear to rotate. During the rotation of the transmission gear, it can come into contact with the elastic metal sheet inside the elastic frame. After the two come into contact, a certain sound will be generated to scare away birds.

[0018] 4. By eliminating the circuit control unit, all bird-repelling actions are achieved through mechanical linkage, avoiding damage to electrical components caused by outdoor humidity, high temperature, lightning strikes and other environments. There is no need to replace the power supply or repair the circuit regularly, reducing maintenance costs by more than 90%. Attached Figure Description

[0021] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0022] like Figures 1-6 As shown, this embodiment provides a bird deterrent device for power transmission lines, including a base 1. The base 1 has an inverted U-shaped structure. Locking mechanisms 2 are symmetrically arranged on the lower sides of the base 1. A support shaft 3 is installed at the top of the base 1, supporting a bushing 4. The bushing 4 is rotatably connected to the outer side of the support shaft 3. The bushing 4 can rotate along the support shaft 3 under the drive of a driving mechanism 5. Multiple sets of driving mechanisms 5 are circumferentially distributed on the upper outer side of the bushing 4. Each driving mechanism 5 includes a support rod 501, a wind cup 502, and a reflector 503. During the process, the wind blows towards the wind cup 502, which is driven by the wind force to rotate the bushing 4 through the support rod 501 to drive away birds. During the rotation, the wind cup 502 drives away birds by reflecting light through the reflector 503. The wind cup 502 has a wind groove 6 in the middle of the back end, which facilitates the wind to enter the wind cup 502. A cleaning mechanism 7 is set inside the wind cup 502 at the back end of the reflector 503. The bushing 4 is connected to the housing 8 through a bearing in the middle of the outer side. The housing 8 can support the transmission mechanism 9. The transmission mechanism 9 is set inside the housing 8.

[0023] The cleaning mechanism 7 includes a main shaft 701 fixed inside the wind cup 502. The main shaft 701 can support the support plate 702. The main shaft 701 has a U-shaped structure, and the support plate 702 is rotatably connected to the middle of the main shaft 701. The support plate 702 can drive the impact plate 703 to swing. The support plate 702 is eccentrically set on the outside of the main shaft 701. The impact plate 703 is installed at the top of the support plate 702. The impact plate 703 can contact the reflector 503 to make it vibrate. The two ends of the impact plate 703 have an arc-shaped structure, and the impact plate 703 is asymmetrically fixed at the top of the support plate 702. The asymmetrically installed impact plate 703 can make the support plate 702 tilt during the static process of the cleaning mechanism 7, so that the impact plate 703 moves away from the reflector 503. Magnetic plates 704 are installed on opposite sides of the support plate 702 and the wind cup 502, and the two sets of magnetic plates 704 are of the same polarity. The swing of the support plate 702 is achieved by two sets of identical magnetic plates 704.

[0024] The transmission mechanism 9 includes a main gear 901 located inside the housing 8. The main gear 901 can drive the secondary gear 902 to rotate. The main gear 901 is fixedly connected to the bushing 4. The secondary gear 902 is meshed on the outer side of the main gear 901. The secondary gear 902 can drive the connecting shaft 903 to rotate. The included angle between the main gear 901 and the secondary gear 902 is 90°. The connecting shaft 903 is fixed in the middle of the secondary gear 902. The connecting shaft 903 can drive the eccentric block 904 to rotate. The eccentric block 904 is fixed at the end of the connecting shaft 903 away from the secondary gear 902. The eccentric block 904 rotates through... During the process, the base plate 905 can be squeezed. The base plate 905 is set above the eccentric block 904. After the base plate 905 is squeezed, it moves upward, thereby driving the wing plate 906 to rotate. The top of the base plate 905 is abutted by two sets of wing plates 906. During the rotation of the wing plate 906, it can simulate the flapping of bird wing plates 906. The wing plate 906 is made of carbon fiber plate with a thickness of 1.5mm, and the surface is printed with eagle feather texture through water transfer printing process. The main frame 907 is set on the outside of the wing plate 906. The main frame 907 can support the wing plate 906. The wing plate 906 is rotatably connected to the main frame (907).

[0025] The locking mechanism 2 includes a locking bolt 201 connected to the base 1. One end of the locking bolt 201 is connected to a locking plate 202 via a bearing, and a rubber pad 203 is fixed to the end of the locking plate 202 away from the locking bolt 201, so that the staff can place the base 1 on the tower crossbar and then rotate the two sets of locking bolts 201. During the rotation of the locking bolts 201, the locking plate 202 is moved towards the tower crossbar, thereby clamping the base 1 onto the tower crossbar.

[0026] The wind cup 502 has a polygonal hemispherical structure, and the surface of the wind cup 502 is made of aluminum-plated reflective film material, which can reflect some light to repel birds during the rotation of the wind cup 502, and the spherical structure of the wind cup 502 can effectively reduce rotational resistance.

[0027] A transmission gear 10 is installed on the lower outer side of the bushing 4, and an elastic frame 11 is provided on the outer side of the transmission gear 10 to facilitate the bushing 4 to drive the transmission gear 10 to contact the elastic frame 11.

[0028] The elastic frame 11 includes multiple sets of mounting rods 1101 fixed in a circular shape on the base 1, and each set of mounting rods 1101 has an elastic metal sheet 1102 fixed on the outside. The elastic metal sheet 1102 and the transmission gear 10 are located at the same horizontal position. The elastic metal sheet 1102 is fixed to the outside of the transmission gear 10 through the mounting rods 1101. During the rotation of the transmission gear 10, it will come into contact with the elastic metal sheet 1102 and generate a sound to drive away birds.

[0029] A whistle 12 is installed on the outside of the support rod 501, and the air inlet of the whistle 12 is opposite to the rotation angle of the drive mechanism 5. It can drive the whistle 12 to rotate during the rotation of the support rod 501. During the rotation of the whistle 12, the wind enters the whistle 12 from the air inlet and produces a sound to scare away birds.

[0030] The base plate 905 is slidably connected to the main frame 907, and the main frame 907 is provided with a sliding groove that matches the base plate 905. The main frame 907 is installed at the back end of the chassis 8, which enables the base plate 905 to be raised and lowered along the main frame 907. The main frame 907 guides the raising and lowering of the base plate 905.

[0031] A locking nut is installed on the base 1 at the corresponding locking bolt 201 to facilitate locking after the locking bolt 201 is rotated, thus preventing loosening.

[0032] The present invention discloses a bird deterrent device for power transmission lines. Its working principle is as follows: In practical use, the operator places the base 1 on the crossbar of the tower and then rotates two sets of locking bolts 201. During the rotation of the locking bolts 201, the locking plate 202 moves towards the crossbar, thereby clamping the base 1 onto the crossbar. After installation, external wind blows towards the wind cup 502. The wind cup 502, driven by the wind, rotates through the support rod 501 to drive the bushing 4 to deter birds. During the rotation, the reflector 503 reflects light to deter birds. During the rotation of the support rod 501, the whistle 12 is driven to rotate. As the whistle 12 rotates, air enters from the air inlet, generating sound to scare away birds. Simultaneously, air enters the wind cup 502 from the wind channel 6 and blows towards the impact plate 703 within the cleaning mechanism 7. The impact plate 703, influenced by the wind, causes the support plate 702 to rotate along the main shaft 701, thus bringing the impact plate 703 into contact with the reflector 503. The vibration generated after the reflector 503 contacts the impact plate 703 causes the dust adhering to its surface to fall off, achieving self-cleaning and preventing dust from obstructing the reflector. The optical mirror 503 reduces reflectivity and improves the bird-repelling effect. After the impact plate 703 contacts the reflector 503, the two sets of magnetic plates 704 move closer together. Since the two sets of magnetic plates 704 are of the same polarity, the repulsion between like poles causes the support plate 702 to move the impact plate 703 away from the reflector 503, thus achieving the swinging of the impact plate 703. Simultaneously, the rotation of the bushing 4 drives the main gear 901 to rotate. The main gear 901 then drives the connecting shaft 903 to rotate via the secondary gear 902. The connecting shaft 903, in turn, drives the eccentric block 904 to rotate. The rotation of block 904 will push the base plate 905 upward. At this time, the base plate 905 will push one end of the wing plate 906 upward and make the wing plate 906 rotate along the main frame 907. The wing plate 906 simulates the flapping effect of bird wings to repel birds. During the rotation of the bushing 4, it can drive the transmission gear 10 to rotate. During the rotation of the transmission gear 10, it can contact the elastic metal sheet 1102 in the elastic frame 11. After the two come into contact, a certain sound will be generated to repel birds. Bird repelling is achieved through sound and light and simulated bionics, which improves the bird repelling effect and efficiency.

[0033] The above are merely further embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
