It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0031] like Figures 1 to 4 As shown, the overhead line alarm device of this embodiment includes: a connecting body 10, a traveling structure 20, a detection structure 30, an alarm structure 40, a camera structure 50 and a controller. The traveling structure 20 is arranged on the connecting body 10, and there is a threading space between the traveling structure 20 and the connecting body 10 for the cable 1 to pass through. The detection structure 30 is connected to the connecting body 10. The alarm structure 40 is connected to the connecting body 10. The camera structure 50 is connected to the connecting body 10 to take an image of the road surface. The controller is signal-connected to the detection structure 30, the alarm structure 40 and the camera structure 50. Among them, the traveling structure 20 and the connecting body 10 can move closer to or farther away from each other to change the height of the threading space.
[0032] Applying the technical solution of this embodiment, the overhead line alarm device includes a connecting body 10, a traveling structure 20, a detection structure 30, an alarm structure 40, a camera structure 50 and a controller. There is a threading space between the traveling structure 20 and the connecting body 10, and the cable 1 passes through the threading space. The connecting body 10 is connected to the traveling structure 20, the detection structure 30, the alarm structure 40 and the camera structure 50. The camera structure 50 is used to take images of the road surface. The controller is signal-connected to the detection structure 30, the alarm structure 40 and the camera structure 50. The traveling structure 20 and the connecting body 10 can move closer to or farther from each other to change the height of the threading space. Through the above-mentioned arrangement, when the traveling structure 20 moves on the cable, it can drive the connecting body 10 to move relative to the cable, and then the connecting body 10 can drive the detection structure 30, the alarm structure 40 and the camera structure 50 to move, so that the overhead line alarm device can be arranged at different positions of the cable. The detection structure 30 can detect the height of the vehicle on the road surface. When the height of the vehicle exceeds the height of the cable 1, the controller can alarm the alarm structure 40. The camera structure 50 can capture the image of the road surface and transmit the image to the controller, so that the controller can determine the height of the vehicle on the road surface according to the image, so that the controller can determine whether the height of the vehicle on the road surface exceeds the height of the cable 1 according to the detection signal of the detection structure 30 and the image captured by the camera structure 50, so as to avoid the misjudgment of the detection structure 30, which causes the alarm structure 40 to issue an alarm and affect the normal walking of the vehicle. The traveling structure 20 and the connecting body 10 can approach or move away from each other, so as to change the height of the threading space, so that when the traveling structure 20 and the connecting body 10 are relatively close, the traveling structure 20 and the connecting body 10 can clamp the cable, so that the relative position of the connecting body 10 and the cable 1 is more stable, so as to avoid the overhead line alarm device from falling off the cable 1, thereby making the position of the overhead line alarm device relative to the cable 1 more stable, facilitating the use of the overhead line alarm device, and avoiding the need to connect a cross bar between the two support rods of the cable 1 to support the overhead line alarm device. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the vehicle height limit warning system needs to be provided with a separate fixed structure.
[0033] The traveling structure 20 and the connecting body 10 can clamp the cable 1, which can prevent the overhead line alarm device from falling off the cable 1 in strong winds. The overhead line alarm device reduces the need for manual patrols, thereby reducing operation and maintenance costs and improving efficiency. The overhead line alarm device can effectively reduce accidents of vehicle collisions with overhead lines and reduce related safety risks by warning drivers of potential dangers in advance. The overhead line alarm device can be expanded and upgraded according to needs, has high scalability, and can adapt to different environmental conditions, such as rain, snow, temperature differences, etc. It is designed to be easy to install and maintain, and can be seamlessly integrated with existing traffic management systems.
[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the overhead line alarm device further includes a first driving member, which is connected between the connecting body 10 and the traveling structure 20, and the first driving member can drive the connecting body 10 to move relative to the traveling structure 20. Through the above arrangement, the first driving member can drive the connecting body 10 to move relative to the traveling structure 20, so that when the connecting body 10 and the traveling structure 20 move relative to each other, the size of the threading space between the traveling structure 20 and the connecting body 10 can be changed, so that the connecting body 10 and the traveling structure 20 can clamp the cable 1 or loosen the cable 1.
[0035] The first driving member includes a steering gear.
[0036] like Figure 4 As shown, in this embodiment, the traveling structure 20 includes a traveling member 21 and a second driving member, an installation space 11 is provided inside the connection body 10, the traveling member 21 is arranged in the installation space 11 so as to be movable up and down, and the second driving member drives and cooperates with the traveling member 21. The second driving member can drive the traveling member 21 to move. The traveling member 21 is arranged in the installation space, so that the connection body 10 can protect the traveling member 21.
[0037] The second driving member includes a driving motor, and the walking member 21 is connected to the output shaft of the driving motor.
[0038] The overhead line alarm device also includes a mounting block, which is connected to the steering gear, and a second driving member is arranged on the mounting block. The steering gear drives the mounting block to rise and fall, and the mounting block drives the second driving member to rise and fall, and then the second driving member can drive the walking member to rise and fall.
[0039] The traveling structure 20 and the connecting body 10 can approach or move away from each other, which means that the distance between the walking member 21 and the top wall of the installation space 11 changes. When the distance between the walking member 21 and the top wall of the installation space 11 becomes larger, the traveling structure 20 and the connecting body 10 approach each other. When the distance between the walking member 21 and the top wall of the installation space 11 becomes smaller, the traveling structure 20 and the connecting body 10 move away from each other.
[0040] like Figure 3 As shown, in this embodiment, a positioning groove 111 is provided on the inner wall of the installation space 11, and when the traveling structure 20 and the connection body 10 are close to each other, the cable 1 is located in the positioning groove 111. The positioning groove 111 provides a holding space for the cable 1, so that when the traveling structure 20 and the connection body 10 are relatively close, the cable 1 can enter the positioning groove 111, thereby making the relative position between the cable 1 and the connection body 10 more stable.
[0041] It should be noted that the positioning groove 111 is provided on the bottom wall of the installation space 11. The cross section of the positioning groove 111 is arc-shaped.
[0042] like Figure 2 As shown, in this embodiment, the connection body 10 is further provided with an opening 12 communicating with the installation space 11, and the width of the opening 12 is greater than or equal to the diameter of the cable 1. The provision of the opening facilitates the cable 1 to enter the installation space 11.
[0043] like Figure 2 As shown, in this embodiment, the opening 12 is located on the side wall of the connection body 10, the distance between one end of the opening 12 and the top wall of the connection body 10 is distance a, and the distance between the middle of the opening 12 and the top wall of the connection body 10 is distance b, wherein the distance a and the distance b satisfy: a ≥ 1.25b. Through the above arrangement, one end of the opening 12 is lower than the middle of the opening 12, so that after the cable enters the installation space 11 through the opening 12, the cable 1 is not easy to fall out of the installation space 11, thereby making the connection between the connection body 10 and the cable 1 more stable.
[0044] The distance a and the distance b also satisfy a≤1.5b. This facilitates the cable 1 to enter the installation space 11. Specifically, the relationship between a and b can be: a=1.25b, a=1.3b, a=1.35b, a=1.4b, a=1.45b or a=1.5b. In this embodiment, the relationship between a and b is a=1.3b.
[0045] It should be noted that the top wall of the connection body 10 refers to the surface of the connection body 10 on which the power generation component is arranged. The distance between one end of the opening 12 and the top wall of the connection body 10 is the distance a. The one end of the opening 12 in the distance a may refer to the first end of the opening 12 or the second end of the opening 12. The distances between the first end of the opening 12 and the second end of the opening 12 and the top wall of the connection body 10 are both the distance a. The opening 12 is arc-shaped, and the middle of the opening 12 protrudes toward the top wall of the connection body 10, so as to prevent the cable 1 from coming out of the installation space 11. The direction from the first end of the opening 12 to the second end of the opening 12 is parallel to the extension direction of the cable 1.
[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the walking member 21 includes a plurality of spaced apart members, the second driving member includes a plurality of second driving members, and the plurality of walking members 21 are arranged one-to-one in correspondence. Through the above arrangement, the plurality of walking members 21 are spaced apart on the cable, so that the relative position of the connecting body 10 connected to the walking member 21 and the cable 1 is more stable.
[0047] The traveling member 21 includes traveling wheels.
[0048] like Figure 3 As shown, in this embodiment, the camera structure 50 includes a first camera 51 and a second camera 52, the first camera 51 is arranged close to the first side of the connecting body 10, and the second camera 52 is arranged close to the second side of the connecting body 10. Through the above arrangement, the first camera 51 and the second camera 52 can simultaneously capture images of the road surface and transmit the images to the controller respectively, so that the controller can more accurately determine whether the vehicle on the road surface is overheight.
[0049] like Figure 3 As shown, in this embodiment, the overhead line alarm device further includes a third driving member 60 disposed on the connecting body 10, and the output shaft of the third driving member 60 is rotatably disposed, and the output shaft of the third driving member 60 is connected to both the first camera 51 and the second camera 52. The third driving member 60 can drive the first camera 51 and the second camera 52 to rotate, so that the first camera 51 and the second camera 52 can rotate according to the direction in which the overhead line alarm device is facing, that is, the first camera 51 and the second camera 52 can rotate according to lanes in different directions.
[0050] The third driving member 60 also includes a driving motor.
[0051] The alarm structure 40 is connected to the output shaft of the third driving member 60, and the alarm structure 40 includes an audible and visual alarm. The corner of the connecting body is provided with an installation bevel, and the alarm structure is installed at the installation bevel, so that the alarm structure can have a larger warning area.
[0052] The detection structure 30 is connected to the output shaft of the third driving member 60 , and the detection structure 30 includes a laser ranging radar and a millimeter wave radar.
[0053] The overhead line alarm device further comprises a power generation assembly arranged on the connection body 10, and the power generation assembly is electrically connected to the controller, the third drive member 60, the second drive member and the first drive member.
[0054] The power generation component comprises a plurality of photovoltaic power generation panels, and the plurality of photovoltaic power generation panels are arranged at intervals on the top of the connection body.
[0055] The overhead line alarm device further includes a mounting member, which includes a mounting shaft, a mounting cylinder and a mounting rod. The mounting shaft is connected between the output shaft of the third driving member 60 and the mounting cylinder. The mounting rod is inserted into the mounting cylinder. The first camera 51 and the second camera 52 are respectively arranged at both ends of the mounting cylinder and are symmetrically arranged about the mounting shaft. The detection structure is connected to a side of the mounting cylinder away from the mounting shaft.
[0056] like Figures 1 to 5As shown, the control method of the overhead line alarm device of this embodiment is used to control the above-mentioned overhead line alarm device. The control method of the overhead line alarm device includes:
[0057] When the wind speed is less than the first preset value, the traveling structure 20 of the overhead line alarm device and the connecting body 10 of the overhead line alarm device remain fixed;
[0058] When the wind speed is greater than or equal to the first preset value and less than the second preset value, the traveling structure 20 and the connecting body 10 are close to each other so that the height of the threading space is less than or equal to the product of the diameter of the cable 1 and the preset multiple;
[0059] When the wind speed is greater than or equal to the second preset value, the traveling structure 20 and the connecting body 10 are close to each other so that the height of the threading space is equal to the diameter of the cable 1;
[0060] Among them, the first preset value is between 0 and 1.6 m / s, the second preset value is between 1.6 m / s and 3.3 m / s, and the preset multiple is between 1.1 and 1.3.
[0061] Through the above method, it is possible to control whether the traveling structure 20 is close to the connecting body 10 according to the wind speed, and control the distance between the traveling structure 20 and the connecting body 10, thereby controlling the height of the threading space so that the relative position between the connecting body 10 and the cable 1 can be stable.
[0062] The second preset value is greater than the first preset value.
[0063] When the wind speed is greater than or equal to the first preset value and less than the second preset value, the traveling structure 20 and the connecting body 10 are close to each other so that the height of the threading space is less than or equal to the product of the diameter of the cable 1 and the preset multiple. The steps include:
[0064] When the height of the threading space is greater than or equal to the third preset value and less than or equal to the product of the diameter of the cable 1 and the preset multiple, the connecting body 10 approaches the traveling structure at the first speed;
[0065] When the height of the threading space is greater than or equal to the diameter of the cable and less than a third preset value, the connecting body 10 approaches the traveling structure at a second speed.
[0066] Through the above-mentioned arrangement, when the height of the threading space is relatively large, the connecting body 10 can approach the traveling structure 20 at a first speed, and when the height of the threading space is relatively small, the connecting body 10 can approach the traveling structure 20 at a second speed. In this way, the speed at which the connecting body 10 approaches the traveling structure 20 can be determined according to the height of the threading space, thereby preventing the connecting body 10 from approaching the traveling structure 20 at a high speed and clamping the cable 1.
[0067] The second speed is less than the first speed. The third preset value is 0.95 times the product of the diameter of the cable 1 and the preset multiple. The first speed may be 2 cm / s. The second speed may be 1 cm / s.
[0068] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0069] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0070] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
