Description

Technical Field

[0001] This invention relates to the field of power grid technology, and in particular to a rapid positioning laser obstacle clearing device. Background Technology

[0002] The safe operation of high-voltage transmission lines is crucial to the power grid. With the rapid development of my country's power grid, transmission lines are ubiquitous. During periods of strong winds and migratory bird seasons, lightweight objects can easily fall onto these lines, posing a serious threat to their safe operation in humid weather. Many power grid regions have begun using laser obstacle removal devices to clear high-altitude debris from a distance. These devices employ high-power lasers to burn off flammable debris, facilitating obstacle removal operations. Existing laser obstacle removal devices are horizontally positioned on a tripod. They emit a laser beam, which reflects back upon encountering an obstacle. An internal sensor receives the reflected beam and calculates the distance between the target object and the device by measuring the time it takes for the beam to travel from emission to reception, thus determining the obstacle's location.

[0003] Because the laser emitter of a laser obstacle clearing device has a limited rotation angle, the overall angle of the device usually needs to be adjusted. Existing devices typically use a motor to adjust the horizontal angle of the laser obstacle clearing device. However, in actual operation, when the laser obstacle clearing device is rotated horizontally by a motor, the rotation angle may be too large or too small because the rotation angle is not limited. This can cause the laser beam emitted by the laser obstacle clearing device to fail to contact the target object, thus affecting the location of the obstacle. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a rapid positioning laser obstacle clearing device, which solves the problem of inaccurate horizontal positioning caused by the lack of horizontal angle limitation in existing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid positioning laser obstacle clearing device includes a laser obstacle clearing device body, a tripod mechanism placed on the ground, and a positioning mechanism mounted on the tripod mechanism for mounting and rapidly positioning the laser obstacle clearing device body. The tripod mechanism includes a horizontally mounted mounting base and four sets of height adjustment components fixedly mounted around the lower surface of the mounting base. The positioning mechanism includes a turntable rotatably embedded in the upper surface of the mounting base, a first motor vertically fixed to the bottom of the mounting base with its drive end passing through the mounting base and fixedly connected to the turntable, an indicator component located between the turntable and the mounting base and rotatably mounted around the turntable on the upper surface of the mounting base, and a receiving box above the turntable for mounting the laser obstacle clearing device body. A vertical rotating assembly is disposed between the turntable and the receiving box and fixed on the upper surface of the turntable; an annular groove is provided around the outer side of the turntable on the upper surface of the mounting base to accommodate the indicator assembly; the indicator assembly includes a first ratchet ring fixed around the bottom wall of the annular groove, a second ratchet ring rotating in the middle of the annular groove and cooperating with the first ratchet ring to achieve unidirectional rotation, a fixed rod vertically fixed on one side of the upper surface of the second ratchet ring and extending to the top of the mounting base after passing through the annular groove, a position indicator plate hinged to the top of the fixed rod, a limit switch fixed to the side of the position indicator plate and electrically connected to the first motor, and a pressing plate fixed on one side of the upper surface of the turntable and cooperating with the limit switch to stop the first motor.

[0007] More preferably, the vertical rotation assembly includes a mounting base fixed to the middle of the upper surface of the turntable, a pair of limiting flanges symmetrically disposed between the receiving box and the mounting base with their inner ends fixedly connected to the corresponding outer wall of the receiving box and their outer ends rotatably connected to the corresponding inner wall of the mounting base, and a second motor fixed to the outer side of any side wall of the mounting base with its drive end passing through the side wall and fixedly connected to the corresponding limiting flange.

[0008] More preferably, each height adjustment assembly includes a linear actuator vertically fixed to the bottom of the mounting base and a support plate hinged to the bottom of the linear actuator and abutting against the ground.

[0009] More preferably, the upper surface of the mounting base is surrounded by indicator scale lines.

[0010] More preferably, the inner sidewall of the receiving box is surrounded by a rubber layer.

[0011] The present invention has the following beneficial effects:

[0012] 1. In this invention, by setting an indicator component, the cooperation of the first ratchet ring and the second ratchet ring is used to realize the unidirectional rotation of the second ratchet ring. When the turntable rotates under the drive of the first motor, the pressing plate rotates accordingly. When the pressing plate touches the limit switch, the limit switch sends a signal to stop the first motor, thereby limiting the horizontal rotation angle of the laser obstacle clearing device body, avoiding the problem that the laser beam cannot contact the target object due to the rotation angle being too large or too small, and improving the positioning accuracy of obstacles;

[0013] 2. In this invention, when the second motor is working, it drives the limiting protrusion to rotate, thereby causing the receiving box to rotate vertically around the axis of the limiting protrusion, realizing the adjustment of the vertical angle of the laser obstacle clearing device body, which can more flexibly aim at the target obstacle.

[0014] 3. In this invention, the height adjustment component in the tripod mechanism can change the height of the mounting base from the ground through the extension and retraction of the linear actuator, adapting to different terrains. The support floor increases the contact area with the ground, improving the stability of the entire instrument. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A rapid positioning laser obstacle clearing device includes a laser obstacle clearing device body 1, a tripod mechanism 2 placed on the ground, and a positioning mechanism 3 mounted on the tripod mechanism 2 for mounting and rapidly positioning the laser obstacle clearing device body 1. The tripod mechanism 2 includes a horizontally arranged mounting base 21 and four sets of height adjustment components 22 respectively fixed around the lower surface of the mounting base 21. The positioning mechanism 3 includes a turntable 31 rotatably embedded in the upper surface of the mounting base 21, a first motor 32 vertically fixed to the bottom of the mounting base 21 with its drive end passing through the mounting base 21 and fixedly connected to the turntable 31, an indicator component 33 located between the turntable 31 and the mounting base 21 and rotatably located around the turntable 31 on the upper surface of the mounting base 21, a receiving box 34 located above the turntable 31 for mounting the laser obstacle clearing device body 1, and a positioning component between the turntable 31 and the receiving box 34. A vertically rotating component 35 is fixedly mounted on the upper surface of the turntable 31; an annular groove 211 is provided around the outer side of the turntable 31 on the upper surface of the mounting base 21 to accommodate the indicator component 33; the indicator component 33 includes a first ratchet ring 331 fixedly mounted on the bottom wall of the annular groove 211, a second ratchet ring 332 rotating in the middle of the annular groove 211 and cooperating with the first ratchet ring 331 to achieve unidirectional rotation, a fixed rod 333 vertically fixed on one side of the upper surface of the second ratchet ring 332 and extending above the mounting base 21 after passing through the annular groove 211, a position indicator plate 334 hinged to the top of the fixed rod 333, a limit switch 335 fixed to the side of the position indicator plate 334 and electrically connected to the first motor 32, and a pressing plate 336 fixed on one side of the upper surface of the turntable 31 and cooperating with the limit switch 335 to stop the first motor 32.

[0021] By setting the indicator component 33, the second ratchet ring 332 is rotated in one direction by cooperating with the first ratchet ring 331 and the second ratchet ring 332. When the turntable 31 rotates under the drive of the first motor 32, the pressing plate 336 rotates accordingly. When the pressing plate 336 touches the limit switch 335, the limit switch 335 sends a signal to stop the first motor 32, thereby limiting the horizontal rotation angle of the laser obstacle clearing device body 1. This avoids the problem that the laser beam cannot contact the target object due to excessive or insufficient rotation angle, thus improving the accuracy of obstacle positioning. In this device, since the rotation direction of the second ratchet ring 332 is opposite to the rotation direction of the drive end of the first motor 32 and both can only rotate in one direction, after the position of the position indicator plate 334 is determined, when the first motor 32 drives the turntable 31 and the pressing plate 36 to rotate, the pressing plate 36 cannot push the position indicator plate 334 to move, thereby enabling the pressing plate 36 to touch the limit switch 335.

[0022] As a possible implementation of this solution, preferably, the vertical rotation component 35 includes a mounting base 351 fixedly disposed in the middle of the upper surface of the turntable 31, a pair of limiting flanges 352 symmetrically disposed between the receiving box 34 and the mounting base 351 with their inner ends fixedly connected to the corresponding outer wall of the receiving box 34 and their outer ends rotatably connected to the corresponding inner wall of the mounting base 351, and a second motor 353 fixedly disposed on the outer side of any side wall of the mounting base 351 with its drive end passing through the side wall and fixedly connected to the corresponding limiting flange 352; the second motor 353 drives the limiting flange 352 to rotate, so that the receiving box 34 rotates vertically around the axis of the limiting flange 352, thereby adjusting the vertical angle of the laser obstacle clearing device body 1, so that the laser beam emitted by it is accurately aligned with the target obstacle, and the clearing operation can be carried out after the positioning is completed.

[0023] As a possible implementation of this solution, preferably, each set of height adjustment components 22 includes a linear actuator 221 vertically fixed to the bottom of the mounting base 21 and a support plate 222 hinged to the bottom of the linear actuator 221 and in contact with the ground; the linear actuator 221 can be an existing device such as an electric push rod, which can perform telescopic movement, and the height of the mounting base 21 from the ground can be changed by adjusting the telescopic length to adapt to different terrains; the support plate 222 increases the contact area with the ground and improves the stability of the leg mechanism 2.

[0024] As a possible implementation of this solution, preferably, the upper surface of the mounting base 21 has an indicator scale line 36 surrounding the turntable 31; the indicator scale line 36 on the mounting base 21 makes it easier for the operator to observe the rotation angle of the turntable 31, which is beneficial for more precise adjustment of the position of the laser obstacle clearing device body 1.

[0025] As a possible implementation of this solution, preferably, the inner wall of the receiving box 34 is surrounded by a rubber layer 341; the rubber layer 341 inside the receiving box 34 can buffer and protect the laser obstacle clearing device body 1, preventing it from being damaged by collision during movement or operation.

[0026] The general working principle of this device is as follows:

[0027] In use, place the tripod mechanism 2 in a suitable ground position, and adjust the linear actuator 221 in the four sets of height adjustment components 22 to keep the mounting base 21 level, ensuring that the support floor 222 is in close contact with the ground to guarantee instrument stability. Install the laser obstacle clearing device body 1 in the housing 34, which is protected by a rubber layer 341.

[0028] Based on the position of the target obstacle, the position indicator plate 334 is rotated, and then the first motor 32 is started, driving the turntable 31 to rotate, which in turn drives the laser obstacle clearing device body 1 to adjust its horizontal angle. During the rotation, the pressing plate 336 rotates with the turntable 31. When the pressing plate 336 touches the limit switch 335, the limit switch 335 sends a signal to stop the first motor 32. At this time, the laser obstacle clearing device body 1 is in a suitable horizontal angle position.

[0029] Start the second motor 353, which drives the limiting protrusion 352 to rotate, causing the receiving box 34 to rotate vertically around the axis of the limiting protrusion 352. Adjust the vertical angle of the laser obstacle clearing device body 1 so that the laser beam emitted is accurately aimed at the target obstacle. After positioning is completed, the clearing operation can be carried out.
