Description

Technical Field

[0001] This invention relates to the field of overhead contact line auxiliary protective equipment, and in particular to an intelligent wind-powered bird-repelling device and method for railway overhead contact lines. Background Technology

[0002] The locations of contact wire disconnect switches, support crossarms, and channel steel supports are usually in open environments and are located at a relatively high position, making them easy places for birds to perch and nest. When birds are active or nesting near contact wire equipment, it can cause problems such as insufficient insulation distance, foreign object contact, short circuit tripping, and difficulties in inspection and maintenance. Therefore, it is necessary to install bird deterrent devices in these locations.

[0003] Existing bird deterrence devices mostly use reflective elements, windmills, and sound to drive birds away. These devices are usually only effective in a fixed direction or under natural wind conditions, and it is difficult to actively adjust the direction of deflection according to the birds' activity. Furthermore, the limited space available for on-site installation of overhead contact lines necessitates that the equipment ensures stable installation, waterproofing, convenient power supply, and reliable long-term outdoor operation. If the rotating structure of the bird deterrent unit, the fan installation structure, and the detection and identification components lack a stable structural fit, problems such as inaccurate deterrence direction, unstable rotation, foreign objects entering the fan, or inconvenient equipment maintenance can easily occur. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent wind-powered bird deterrent device for railway catenary. Through the structural cooperation between the bottom mounting base, support shell, slewing bearing base, slewing drive component, vertical support frame, waterproof box, fan assembly, image acquisition assembly and radar detection assembly, the waterproof box can rotate horizontally relative to the bottom mounting base, and the fan assembly outputs bird deterrent airflow towards the target area, thereby improving the bird deterrent direction adjustment capability and outdoor installation adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart wind-powered bird deterrent device for railway catenary includes a bottom mounting base, a support housing on the bottom mounting base, and a slewing bearing seat disposed inside the support housing via a bearing assembly. The rotary bearing seat is connected to the vertical support frame, and a waterproof box is installed on the vertical support frame; The waterproof box is equipped with a fan assembly, and the front side of the waterproof box is provided with an air outlet corresponding to the fan assembly. A protective grille is provided at the air outlet. The support housing is provided with a rotary drive component, which is connected to the rotary bearing seat to drive the rotary bearing seat, vertical support frame and waterproof box to rotate horizontally relative to the bottom mounting base; The waterproof housing is equipped with an image acquisition component and a radar detection component. A control board is installed inside the waterproof housing. The control board is electrically connected to the rotary drive component, the fan component, the image acquisition component, and the radar detection component.

[0006] Furthermore, the bottom mounting base includes an elongated mounting plate, the support housing is disposed in the middle of the elongated mounting plate, and mounting holes are respectively provided at both ends of the elongated mounting plate.

[0007] Furthermore, the rotary drive includes a servo motor, a drive gear, and a driven transmission component. The servo motor is fixedly installed inside the support housing. The drive gear is installed on the output shaft of the servo motor. The drive gear meshes with the driven transmission component, and the driven transmission component is connected to the rotary bearing seat.

[0008] Furthermore, the support housing is provided with a plurality of radial support arms, which are arranged circumferentially around the rotary bearing seat. One end of each radial support arm is connected to the support housing, and the other end is connected to the mounting part of the bearing assembly.

[0009] Furthermore, the vertical support frame includes two lateral support plates arranged opposite each other, and the waterproof box is disposed between the two lateral support plates and connected to the two lateral support plates through a connecting shaft.

[0010] Furthermore, a pitch drive mechanism is provided between the vertical support frame and the waterproof box. The pitch drive mechanism includes a servo motor and rotating shafts respectively connected to both sides of the servo motor. The rotating shafts are connected to the vertical support frame to drive the waterproof box to swing up and down around the horizontal axis relative to the vertical support frame.

[0011] Furthermore, the waterproof box includes a box body and a detachable cover plate. The detachable cover plate is disposed at the upper end of the box body and is connected to the box body by fasteners.

[0012] Furthermore, the air outlet is a circular air outlet, the protective grille includes horizontal grille bars and vertical grille bars that are arranged in a cross pattern, and the air outlet end of the fan assembly is arranged facing the circular air outlet.

[0013] Furthermore, the radar detection assembly includes a left radar detection module and a right radar detection module, which are respectively disposed on the left and right sides of the waterproof housing; the image acquisition assembly is disposed on the front side of the waterproof housing and is arranged in the same direction as the air outlet.

[0014] This invention also provides a smart wind-powered bird deterrence method for overhead contact lines, comprising the following steps: S1, the radar detection component installed on the waterproof box is used to detect the preset protection area around the contact network equipment and obtain the detection signal corresponding to the moving target entering the preset protection area; S2, the control board determines the orientation of the moving target relative to the waterproof box based on the detection signal, and controls the rotary drive to rotate the rotary bearing seat, causing the vertical support frame and the waterproof box to rotate around the vertical axis, so that the image acquisition direction of the image acquisition component is towards the area where the moving target is located. S3, acquire a target image of the area where the moving target is located using the image acquisition component, and determine whether the moving target is a bird target based on the target image; S4, when the moving target is identified as a bird target, the positional deviation of the bird target relative to the image acquisition direction is determined according to the position of the bird target in the target image, and the rotation drive and pitch drive mechanism are controlled to move according to the positional deviation, so that the image acquisition direction of the image acquisition component and the air outlet direction of the fan component are toward the bird target. S5, control the start of the fan assembly, so that the fan assembly outputs bird-repelling airflow to the area where the bird target is located through the air outlet; S6, during the output of the bird-repelling airflow, the radar detection component and image acquisition component continuously detect the bird target, and adjust the horizontal rotation angle and pitch angle of the waterproof box according to the position change of the bird target; when the bird target leaves the preset protection area or the bird target is not detected within a preset time, the fan component is controlled to stop running.

[0015] This invention provides stable rotational support for the vertical support frame and waterproof housing by installing a support housing on the bottom mounting base and a rotating bearing seat within the support housing via a bearing assembly. Simultaneously, a rotational drive component is connected to the rotating bearing seat, enabling the waterproof housing to rotate horizontally relative to the bottom mounting base, allowing the airflow direction of the fan assembly to be adjusted according to the detection area. The fan assembly is housed within the waterproof housing, with an air outlet corresponding to the fan assembly on the front side. A protective grille is installed at the air outlet, which both creates a directional bird-repelling airflow and reduces the risk of foreign objects entering the fan assembly.

[0016] This invention also provides an intelligent wind-powered bird-repelling method for overhead contact lines. A radar detection component performs initial detection of moving targets within a preset protection area. Based on the detection signal, the waterproof housing rotates towards the area where the moving target is located, expanding the target detection range. Furthermore, an image acquisition component acquires images of the target and confirms whether the moving target is a bird, reducing the possibility of other moving objects causing the fan assembly to start erroneously. Once the moving target is confirmed as a bird, the horizontal rotation angle and pitch angle of the waterproof housing are controlled according to the bird's positional deviation in the target image, ensuring that the image acquisition direction and the fan assembly's airflow direction are aligned with the bird target. This improves the accuracy of the bird-repelling airflow and adapts to bird activity areas at different locations and heights. During the bird-repelling process, continuous detection of bird targets and adjustment of the airflow direction based on their positional changes enable continuous repelling of moving birds. The fan assembly stops when the bird target leaves the preset protection area or when no bird target is detected within a preset time, reducing ineffective operation and energy consumption of the fan assembly and improving the device's continuous operation capability in outdoor environments with overhead contact lines.

Detailed Implementation

[0019] The specific embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the following embodiments are used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] like Figures 1 to 6 As shown, this embodiment provides an intelligent wind-powered bird-repelling device for railway catenary. The device is installed on the catenary disconnector switch or channel steel bracket to detect and drive away birds around the catenary equipment.

[0021] The device includes a bottom mounting base 1, which is used to support the entire machine and is fixedly connected to the on-site support structure.

[0022] The bottom mounting base 1 includes an elongated mounting plate 11 that extends horizontally. Mounting holes 12 are provided at both ends of the elongated mounting plate 11 for U-bolts to pass through, thus securing the bottom mounting base 1 to the disconnector channel steel. A support housing 2 is located in the middle of the elongated mounting plate 11, protruding upwards relative to the elongated mounting plate 11 to form an installation space for accommodating the slewing bearing component and the drive component.

[0023] A slewing bearing seat 4 is disposed within the support housing 2 via a bearing assembly 3. The bearing assembly 3 forms a slewing support between the support housing 2 and the slewing bearing seat 4, allowing the slewing bearing seat 4 to rotate relative to the support housing 2 about a vertical axis. The slewing bearing seat 4 is located in the central region of the support housing 2, and its upper end is connected to the vertical support frame 5. Thus, when the slewing bearing seat 4 rotates, it can drive the vertical support frame 5 to rotate horizontally synchronously.

[0024] For mounting the bearing assembly 3, a plurality of radial support arms 14 are provided inside the support housing 2. The plurality of radial support arms 14 are arranged circumferentially around the central support housing 2. One end of each radial support arm 14 is connected to the support housing 2, and the other end is connected to the mounting part of the bearing assembly 3.

[0025] A rotary drive component 8 is also provided inside the support housing 2. In this embodiment, the rotary drive component 8 includes a servo motor 81, a drive gear 82, and a driven transmission component 83. The servo motor 81 is fixedly installed inside the support housing 2, the drive gear 82 is installed on the output shaft of the servo motor 81, and the driven transmission component 83 is rotatably connected to the rotary bearing seat 4. The driven transmission component 83 drives the rotary bearing seat 4 to rotate together, and the drive gear 82 meshes with the driven transmission component 83. When the servo motor 81 is activated, the drive gear 82 rotates with the output shaft of the servo motor 81, and drives the rotary bearing seat 4 to rotate around the vertical axis through the driven transmission component 83, thereby causing the vertical support frame 5 and the waterproof box 6 to rotate horizontally relative to the bottom mounting base 1.

[0026] The vertical support frame 5 is connected to the rotary bearing seat 4. The vertical support frame 5 includes two lateral support plates 51 arranged opposite each other, with the two lateral support plates 51 spaced apart along the left and right direction of the waterproof box body 6. The waterproof box body 6 is mounted on the two lateral support plates 51 and fixed with bolts.

[0027] In a further embodiment, a pitch drive mechanism 16 is provided between the vertical support frame 5 and the waterproof housing 6. The pitch drive mechanism 16 includes a servo motor 161 and rotating shafts 162 respectively connected to both sides of the servo motor 161. The two rotating shafts 162 are coaxially arranged and are respectively connected to the vertical support frame 5 for transmission. When the servo motor 161 is activated, it can drive the waterproof housing 6 to swing left and right relative to the vertical support frame 5 around the horizontal axis through the two rotating shafts 162. Thus, based on the horizontal adjustment of the waterproof housing 6 achieved by the rotary drive component 8 in the support housing 2, the pitch drive mechanism 16 further achieves the vertical angle adjustment of the waterproof housing 6, so that the air outlet direction of the fan assembly 7 and the acquisition direction of the image acquisition component 9 in the waterproof housing 6 can cover different height areas.

[0028] The waterproof enclosure 6 includes an enclosure body 61 and a removable cover 62. The enclosure body 61 is a shell structure with a receiving cavity. The removable cover 62 is located at the upper end of the enclosure body 61 and is connected to the enclosure body 61. The removable cover 62 is used to close the upper opening of the enclosure body 61, while facilitating the installation, maintenance, or replacement of the fan assembly 7 and related wiring inside the enclosure body 61.

[0029] The fan assembly 7 is housed within the waterproof housing 6. An air outlet 63 corresponding to the fan assembly 7 is located on the front side of the waterproof housing 6, with the air outlet of the fan assembly 7 facing the air outlet 63. The air outlet 63 is circular and equipped with a protective grille. The protective grille includes intersecting horizontal and vertical grille bars. These bars divide the air outlet 63 into multiple ventilation zones, ensuring that the airflow from the fan assembly 7 is discharged through the air outlet 63 while preventing larger foreign objects from entering the waterproof housing 6, thus protecting the fan assembly 7.

[0030] An image acquisition device and a radar detection device are mounted on the waterproof housing, and a control board is housed inside the waterproof housing. The aforementioned image acquisition device, radar detection device, and control board can all be implemented using existing cameras, radar detectors, and control circuit boards in the field. The specific image recognition algorithm, radar detection algorithm, control program, and circuit principle are not the focus of this application's improvement. This application focuses on defining the installation positional relationship and structural fit between the aforementioned existing electronic devices and the waterproof housing, air outlet, fan assembly, rotary drive component, and pitch drive mechanism.

[0031] Specifically, the image acquisition device is positioned on the front of the waterproof housing, with its acquisition direction aligned with or substantially aligned with the air outlet's outlet direction. This arrangement ensures that the area captured by the image acquisition device corresponds to the blowing area of ​​the fan assembly, allowing the airflow from the fan assembly to be directed towards the target area corresponding to the image acquisition device. This avoids the problem of the driving direction deviating due to the inconsistency between the image acquisition direction and the air outlet direction.

[0032] The radar detection devices are mounted on the waterproof housing and can detect targets on both the left and right sides of the housing. When a left-right partitioned detection structure is used, the radar detection devices can include radar detectors positioned on the left and right sides of the waterproof housing, respectively. These two detectors detect moving targets on the left and right sides of the housing, providing a directional trigger for the horizontal rotation of the housing. Thus, when a target is detected on one side, the control board can control the rotation drive based on the detection signal output by the radar detection devices, causing the rotation support to drive the vertical support frame and the waterproof housing to rotate horizontally in the corresponding direction.

[0033] The control board is housed within the waterproof enclosure and is electrically connected to the rotary drive, fan assembly, image acquisition device, and radar detection device. The control board can be a conventional control circuit board in the art, used to receive signals from the radar detection device and image acquisition device, and to output control signals to the rotary drive, fan assembly, and pitch drive mechanism. When the radar detection device detects a moving target, the control board controls the rotary drive to rotate the waterproof enclosure horizontally; when bird deterrence is required, the control board controls the fan assembly to start, causing it to output airflow through the outlet; when a pitch drive mechanism is installed, the control board can also control the pitch drive mechanism to swing the waterproof enclosure up and down around a horizontal axis, allowing the image acquisition direction and airflow direction to cover different height areas. The above control process can be implemented using existing control methods, and this application does not limit its software processing logic.

[0034] The intelligent wind-powered bird deterrent device for overhead contact lines in this embodiment also includes a solar power supply component 17. The solar power supply component 17 includes a solar panel 171, a solar panel bracket 172, a battery, and a power connection cable. The solar panel 171 is mounted on the solar panel bracket 172, which is used to mount the solar panel 171 onto a support structure near the overhead contact line. The battery is electrically connected to both the solar panel 171 and the power connection cable. The solar panel 171 converts solar energy into electrical energy and charges the battery; the battery supplies power to the control board and related electrical components via the power connection cable.

[0035] Through the above structure, the present invention integrates the bottom mounting structure, horizontal rotation structure, pitch swing structure, fan outlet structure, detection and acquisition structure and solar power supply structure into the same bird deterrent device, which can adapt to the outdoor installation environment of the contact wire and improve the flexibility and stability of wind-driven bird deterrent direction adjustment.

[0036] This embodiment provides an intelligent wind-powered bird-repelling method for overhead contact lines, implemented using the intelligent wind-powered bird-repelling device for overhead contact lines described in any of the preceding embodiments. The bird-repelling device is installed on the overhead contact line disconnector, support crossarm, channel steel bracket, or other locations where birds need to be prevented from alighting or nesting. Through the coordinated operation of radar detection components, image acquisition components, control board, rotation drive component, pitch drive mechanism, and wind turbine components, it detects, confirms, locates, and drives away bird targets entering a preset protection area using wind power. The method specifically includes the following steps.

[0037] S1 uses radar detection components to detect the pre-defined protected area around the overhead contact line equipment.

[0038] Pre-defined protection zones can be set based on the installation location of bird deterrent devices, the structure of overhead contact line equipment, and areas requiring special protection. For example, the areas above disconnect switches, around the crossarms of support posts, and above channel steel supports that are prone to birds perching or nesting can be designated as pre-defined protection zones.

[0039] The radar detection component continuously or at preset time intervals transmits detection signals to a preset protection area and receives echo signals reflected from objects within the preset protection area. The control board determines whether a moving target exists within the preset protection area based on the signals output by the radar detection component. When a moving target enters the preset protection area, the radar detection component outputs a detection signal corresponding to the moving target to the control board.

[0040] When the radar detection assembly includes a left-side radar detection module and a right-side radar detection module, the left-side radar detection module is used to detect the area corresponding to the left side of the waterproof housing, and the right-side radar detection module is used to detect the area corresponding to the right side of the waterproof housing. The control board can determine whether the moving target is located in the left or right area of ​​the waterproof housing based on the radar detection module that outputs the detection signal. Alternatively, the radar detection assembly can employ a radar detector capable of outputting the azimuth information of the moving target, and the control board can determine the azimuth of the moving target relative to the waterproof housing based on the azimuth information.

[0041] S2 controls the waterproof box to rotate toward the area where the moving target is located.

[0042] After receiving the detection signal from the radar detection component, the control board determines the orientation of the moving target relative to the waterproof housing based on the detection signal and outputs a rotation control signal to the rotary drive component. The rotary drive component drives the rotary bearing seat to rotate around the vertical axis through the driving gear and the driven transmission component. The rotary bearing seat further drives the vertical support frame and the waterproof housing to rotate synchronously.

[0043] When the moving target is located in the left area of ​​the waterproof housing, the control panel controls the rotary drive to rotate in the direction that makes the waterproof housing face the left area; when the moving target is located in the right area of ​​the waterproof housing, the control panel controls the rotary drive to rotate in the direction that makes the waterproof housing face the right area. As the waterproof housing rotates, the image acquisition component located on the front of the waterproof housing rotates synchronously with the waterproof housing, so that the image acquisition direction of the image acquisition component is towards the area where the moving target is located.

[0044] In this step, the radar detection component is used to perform preliminary detection of moving targets over a large area, while the image acquisition component does not need to acquire images of the entire preset protection area at all times, which can reduce invalid data generated during image acquisition and processing.

[0045] S3: Acquire target images and determine whether the moving target is a bird.

[0046] Once the image acquisition component is oriented towards the area where the moving target is located, the control board controls the image acquisition component to acquire the target image of that area. The image acquisition component can continuously acquire multiple frames of target images and send them to the control board for processing.

[0047] The control panel can extract the moving region from the target image to obtain the target image region corresponding to the moving target, and process the target image region using a pre-set bird image recognition program. The bird image recognition program can determine whether the moving target is a bird target based on the external contour, size ratio, motion state and / or image features of the moving target, or it can output the bird recognition result using a pre-trained bird recognition model.

[0048] When the moving target is not identified as a bird, the control panel does not activate the fan assembly and continues to receive detection information from the radar detection and image acquisition components. When the moving target is identified as a bird, the control panel executes subsequent direction adjustments and wind-driven deflection procedures. This avoids the fan assembly being directly triggered by train component shaking, tree branch swaying, fallen leaves, or other non-bird moving objects.

[0049] S4, adjust the horizontal rotation angle and pitch angle of the waterproof box according to the positional deviation of the bird target.

[0050] Once the moving target is identified as a bird, the control panel determines the bird's location in the target image and compares this location with a reference position corresponding to the image acquisition direction. This reference position can be the center of the target image or a pre-defined target area within the image.

[0051] Specifically, the width and height of the target image can be denoted as W and H, respectively, the center position of the target image can be denoted as (u0, v0), and the center position of the bird target can be denoted as (u, v). Then, the lateral and longitudinal positional deviations of the bird target relative to the center position of the image are respectively: Lateral positional deviation: Δu = u - u0; Longitudinal position deviation: Δv = v - v0.

[0052] When the lateral position deviation exceeds the preset allowable lateral range, the control board outputs a control signal to the rotary drive component according to the direction of the lateral position deviation, so that the rotary bearing seat drives the vertical support frame and the waterproof box to rotate horizontally in the direction of reducing the lateral position deviation.

[0053] When the longitudinal position deviation exceeds the preset longitudinal allowable range, the control board outputs a control signal to the pitch drive mechanism according to the direction of the longitudinal position deviation, so that the pitch drive mechanism drives the waterproof box to swing up or down around the horizontal axis, so as to reduce the longitudinal position deviation of the bird target relative to the image acquisition direction.

[0054] The control panel continuously adjusts the horizontal rotation and pitch angles of the waterproof housing until the bird target is located in the center area of ​​the target image or within the preset target area. Since the image acquisition direction of the image acquisition component is consistent with or substantially consistent with the air outlet direction of the fan component, when the bird target is located in the center area of ​​the target image or within the preset target area, the air outlet direction of the fan component simultaneously faces the area where the bird target is located.

[0055] S5 activates the fan assembly and outputs bird-repelling airflow to the area where the bird target is located.

[0056] After the airflow direction is adjusted, the control board outputs a start signal to the fan assembly, causing the fan assembly to start running. The airflow generated by the fan assembly is discharged outward through the air outlet on the front side of the waterproof housing, forming a directional bird-repelling airflow towards the area where the bird target is located.

[0057] The protective grille at the air outlet allows the bird-repelling airflow to pass through while preventing larger foreign objects from entering the waterproof housing. By first determining the location of the bird target and then controlling the airflow output of the fan assembly, the bird-repelling airflow can be concentrated on the area where the bird target is located, reducing ineffective blowing caused by the misalignment of the airflow direction with the target direction.

[0058] S6 continuously detects bird targets while outputting bird-repelling airflow.

[0059] During the operation of the wind turbine components, the radar detection and image acquisition components continue to detect bird targets. The control board determines the positional changes of the bird targets based on the target images continuously acquired by the image acquisition components and recalculates the positional deviation of the bird targets relative to the image acquisition direction.

[0060] When the bird target moves horizontally, the control panel controls the rotary drive to adjust the horizontal rotation angle of the waterproof housing; when the bird target moves vertically, the control panel controls the pitch drive to adjust the pitch angle of the waterproof housing; when the bird target changes position in both the horizontal and vertical directions simultaneously, the control panel controls the rotary drive and pitch drive respectively to ensure that the image acquisition direction and the air outlet direction continue to face the bird target.

[0061] When the radar detection component detects that the bird target has left the preset protection area, or when the image acquisition component fails to acquire a target image containing the bird target within a preset time, the control board determines that the bird deterrence process has ended and outputs a stop signal to the fan component, causing the fan component to stop running.

[0062] The preset protection area, the lateral allowable range, the longitudinal allowable range, and the preset time for when no bird targets are detected can be preset according to the resolution of the image acquisition component, the effective air outlet distance of the fan component, the response speed of the slewing drive and the pitch drive mechanism, and the on-site environment of the overhead contact line. This embodiment does not impose specific limitations on these settings.

[0063] Using the above method, the radar detection component first completes the preliminary detection and orientation determination of the moving target, the image acquisition component further completes the confirmation and location determination of the bird target, the slewing drive and pitch drive mechanism adjust the orientation of the waterproof box according to the positional deviation of the bird target, and the fan component then outputs bird-repelling airflow towards the area where the bird target is located, and continuously adjusts the airflow direction according to the positional changes of the bird target during the bird-repelling process, thus forming a closed-loop bird-repelling process in which moving target detection, bird target confirmation, airflow direction adjustment, wind-driven repelling and target tracking are mutually coordinated.
