[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 As shown, this invention provides a mobile laser-sensing self-adjusting Fresnel lens device to assist in slope weathering, including a mobile slope aerial cableway device and a laser-sensing self-adjusting Fresnel lens device 5; the mobile slope aerial cableway device includes a traction cable 4, a drive system 2, and a hoisting system; the laser-sensing self-adjusting Fresnel lens device 5 includes a laser system, a Fresnel lens device 13, an analysis system 19, and a height adjustment system; the traction cable 4 is erected between the top and bottom of the slope and connected to the drive system 2; the hoisting system is installed on the traction cable 4, and the laser-sensing self-adjusting Fresnel lens device 5 is fixed to the hoisting system; the laser system is used to acquire slope height information, the Fresnel lens device 13 is used to focus sunlight onto the slope surface, and the analysis system 19 is used to control the height adjustment system to adjust the position of the Fresnel lens device 13 according to the acquired slope height information.

[0024] This invention, through the combination of a mobile slope aerial cableway device and a laser-sensing self-adjusting Fresnel lens device 5, can construct a mobile working platform that can cover the entire slope working surface, so that focused weathering treatment is no longer limited to a fixed point, and realizes efficient and continuous automated operation.

[0025] Further optimization of the scheme: the drive system 2 includes a drum 1 and a drive motor set at the bottom of the slope, and an upper movable support vehicle 9 set at the top of the slope; the drum 1 is connected to the drive motor; a traction cable pulley 11 is installed at the top of the upper movable support vehicle 9, and the drum 1 and the traction cable pulley 11 are connected by a traction cable 4; the drive motor drives the drum 1 to rotate to realize the reciprocating motion of the traction cable 4.

[0026] By specifically configuring the drive system 2 as consisting of a bottom drum 1, a drive motor, a top movable support trolley 9, and a traction cable pulley 11, a stable and reliable closed-loop traction system can be formed. The drive motor controls the drum 1 to wind up and unwind the traction cable 4, enabling precise control of the entire device's movement along the slope's incline, providing a power foundation for continuous operation.

[0027] The scheme is further optimized. The hoisting system includes a gantry 7 and a pulley 6. The pulley 6 is set on the traction cable 4. The gantry 7 is connected to the pulley 6. The gantry 7 is used to suspend the laser-sensing self-adjusting Fresnel lens device 5.

[0028] The laser-sensing self-adjusting Fresnel lens device 5 can be suspended on the traction cable 4 and moved smoothly using the hoisting system consisting of pulleys 6 and a hanger 7. The pulleys 6 reduce movement resistance, while the hanger 7 provides a stable connection and support, ensuring the stability of the core working components during movement.

[0029] Further optimization of the scheme: the laser system includes a laser emitter 16 and a data receiver 18 mounted on a Fresnel lens device 13. The laser system is used to emit laser light onto the slope surface and receive reflected signals to obtain slope height information.

[0030] By integrating the laser emitter 16 and data receiver 18 onto the Fresnel lens device 13 to form a laser system, real-time, synchronous measurement of the distance to the normal direction of the slope surface directly below or in front of the device can be achieved. The acquired height information serves as the direct basis for subsequent focusing adjustments, ensuring the accuracy and immediacy of the sensing.

[0031] To further optimize the scheme, the analysis system 19 is connected to the laser system. The analysis system 19 is used to process the data acquired by the laser system and calculate the height adjustment parameters required for the Fresnel lens 15 in the Fresnel lens device 13.

[0032] By analyzing the settings of the analysis system 19, the raw distance and angle signals collected by the laser system can be converted into specific command parameters for controlling the spatial pose of the Fresnel lens 15. This analysis system acts as the "brain," serving as the core processing unit for realizing the device's self-adjustment and intelligence.

[0033] Further optimization of the scheme: the height adjustment system includes a small motor 20, a main gear 17, a secondary gear 22, and a rotating linkage 21. The small motor 20 is connected to the secondary gear 22 through the rotating linkage 21, and the secondary gear 22 meshes with the main gear 17. The small motor 20 drives the secondary gear 22 to rotate the main gear 17, thereby adjusting the attitude of the Fresnel lens device 13.

[0034] The height adjustment system, consisting of a small motor 20, a gear set, and a linkage, can convert the electrical control commands issued by the analysis system 19 into precise mechanical actions. The small motor 20 serves as the power source, amplifying the torque and transmitting the motion through the gear set (the secondary gear 22 drives the main gear 17), ultimately driving the Fresnel lens device 13 to rotate around its axis. This rotation allows for upward or downward movement to adjust whether the lens can focus on the rock.

[0035] Further optimization of the scheme: the mobile slope aerial cableway device also includes a ground support frame 8, which is installed on the upper mobile support vehicle 9. The ground support frame 8 is used to provide support and fixation for the upper mobile support vehicle 9; a transverse support beam 10 is provided on the upper mobile support vehicle 9.

[0036] By installing a ground support frame 8 and a transverse support beam 10 on the upper mobile support vehicle 9, the stability and load-bearing capacity of the top anchor point of the cableway system can be greatly enhanced. The ground support frame 8 can be deployed to increase the stress area and prevent the vehicle from sinking or overturning; the transverse support beam 10 can balance the lateral force brought by the traction cable 4, ensuring the stability and safety of the entire overhead structure.

[0037] To further optimize the design, a transparent plate 12 is provided on the outside of the laser-sensing self-adjusting Fresnel lens device 5. The transparent plate 12 is used to protect the optical and mechanical components inside the laser-sensing self-adjusting Fresnel lens device 5.

[0038] By setting a transparent plate 12 on the outside of the device, a sealed, dustproof, and rainproof clean working environment can be provided for the internal precision components such as the Fresnel lens device 13, laser emitter 16, and gear transmission mechanism, while allowing sunlight to pass through efficiently, ensuring that the device can operate reliably for a long time in harsh outdoor environments.

[0039] The scheme is further optimized by providing a traction cable hole 14 on the laser-sensing self-adjusting Fresnel lens device 5, which is then mounted on the traction cable 4 through the traction cable hole 14.

[0040] By providing a traction cable hole 14 on the housing of the laser-sensing self-adjusting Fresnel lens device 5, the traction cable 4 can pass directly through the main body of the device. This connection method not only provides a movement path but also plays an important guiding and limiting role, preventing the device from twisting or swinging significantly during wind or movement, and ensuring that its movement trajectory maintains a relatively stable relationship with the slope surface.

[0041] In a further optimized design, threads are provided on the outer wall of the Fresnel lens device 13, and the main gear 17 is sleeved on the outer wall of the Fresnel lens device 13 and threadedly connected to the Fresnel lens device 13.

[0042] By providing threads on the outer wall of the Fresnel lens device 13 and connecting the main gear 17 to it in a threaded pair, the rotational motion of the main gear 17 can be converted into linear motion of the Fresnel lens device 13 along its optical axis. When it is necessary to adjust the focusing distance (i.e., the amount of extension of the Fresnel lens device 13 relative to the transparent plate 12), the analysis system 19 can control the small motor 20 to drive the main gear 17 to rotate through the gears. Since the main gear 17 is restricted to rotation and cannot move axially, the Fresnel lens device 13, which is threaded to it, will move forward or backward accordingly, thereby achieving precise adjustment of the focusing function.

[0043] The mobile laser-sensing self-adjusting Fresnel lens device for assisting slope weathering provided by this invention is implemented as follows: First, the system is set up. The upper mobile support vehicle 9 is moved to a suitable position at the top of the slope, and the ground support frame 8 on it is unfolded for stable support. The drive system 2 with drum 1 (which can be integrated into the drive trolley 3) is placed at the bottom of the slope. One end of the traction cable 4 is wound around the drum 1, and the other end is pulled to the top of the slope, passed through the traction cable pulley 11 on the top of the upper mobile support vehicle 9, and then lowered to form a closed loop. Next, the laser-sensing self-adjusting Fresnel lens device 5 is installed at the appropriate initial position of the traction cable 4 through the traction cable hole 14 and the hoisting system (pulley 6 and hanger 7).

[0044] After system startup, it enters an automated operation cycle. First, laser emitter 16 emits a laser beam towards the slope surface directly below the device, and data receiver 18 receives the reflected signal and transmits it to analysis system 19. Analysis system 19 calculates the real-time distance between the device and the slope surface based on the laser flight time or phase difference, and calculates the local normal direction of the slope surface based on information such as the position of the reflected light spot. Based on this terrain data and a pre-installed sunlight sensor, analysis system 19 calculates the focusing distance required to accurately focus sunlight onto the measurement point after passing through Fresnel lens 15.

[0045] Subsequently, the analysis system 19 sends control commands to the height adjustment system. The small motor 20 starts, driving the secondary gear 22 to rotate via the rotating linkage 21. The secondary gear 22 then drives the main gear 17, which meshes with it, to rotate. If the focusing distance needs adjustment, the rotation of the main gear 17, through its engagement with the threads on the outer wall of the Fresnel lens device 13, drives the Fresnel lens device 13 to move linearly along the optical axis. After adjustment, sunlight shines through the transparent plate 12 onto the Fresnel lens 15, converging into a high-energy-density light spot that is projected onto the slope rock surface. The localized high temperature causes thermal stress fracturing in the rock, thereby accelerating weathering.

[0046] Once the current area has achieved the desired treatment effect, the analysis system 19 issues a movement command. The motor of the drive system 2 starts, driving the drum 1 to rotate and retract the traction cable 4, moving the entire laser-sensing self-adjusting Fresnel lens device 5 along the traction cable 4 to the next area to be treated. After reaching the new position, the process of laser measurement, data analysis, lens adjustment, and focused irradiation is repeated, in a cyclical manner, until continuous and automated accelerated weathering treatment of the entire slope working surface within the device's working range is completed. Then, the ground support frame 8 is retracted, and the device is moved laterally along the horizontal direction of the slope by the drive trolley 3 and the upper moving support vehicle 9, moving the entire device to an adjacent working area. The above operations are repeated until continuous and automated accelerated weathering treatment of the entire slope working surface is completed. Throughout the process, the device achieves full automation of movement, sensing, analysis, adjustment, and operation, significantly improving work efficiency and processing quality, and greatly reducing the intensity of manual labor and safety risks.

[0047] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
