Description

Technical Field

[0001] This utility model relates to the field of road surface monitoring technology, and in particular to a road surface settlement difference monitoring device. Background Technology

[0002] Road surface settlement refers to the vertical subsidence of the road surface, usually caused by natural factors or human activities. Its core mechanism is the compression and consolidation of the subgrade or foundation soil layers, which leads to a decrease in road surface elevation.

[0003] In existing technologies, during long-term use, GNSS road settlement monitoring instruments are prone to weed growth around their installation area. As the weeds grow, excessively tall weeds may obstruct the signal receiving module of the monitoring instrument, interfering with the stable transmission of GNSS satellite signals and causing a decrease in positioning accuracy. Manually clearing weeds regularly not only increases maintenance costs, but also makes it difficult to guarantee the timeliness and convenience of clearing operations in remote road sections or complex terrain areas. Weed obstruction can easily lead to distorted monitoring data or abnormal equipment operation. Utility Model Content

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, according to Figures 1-4 As shown, a road surface settlement difference monitoring device includes a GNSS road surface settlement monitoring instrument body 1, a cutting component 2 on the outer wall of the GNSS road surface settlement monitoring instrument body 1, and a fixing component 3 fixedly connected to the outer wall of the GNSS road surface settlement monitoring instrument body 1.

[0024] The cutting assembly 2 includes a mounting groove 201 formed on the outer wall of the GNSS road settlement monitoring instrument body 1. A first gear 202 is rotatably connected to the inner wall of the mounting groove 201 via a bearing. Several fixed brackets 203 are fixedly connected to the top of the first gear 202 at equal intervals in a ring. A first electric push rod 204 is fixedly connected to the top of each of the fixed brackets 203. A moving block 205 is fixedly connected to the output end of each of the first electric push rods 204. A cutting blade 206 is fixedly connected to the outer wall of each of the moving blocks 205. A mounting frame 207 is fixedly connected to the outer wall of the GNSS road settlement monitoring instrument body 1. A rotating rod is rotatably connected to the top of the mounting frame 207 via a bearing. A second gear 208 is fixedly connected to the outer wall of the rotating rod. The outer wall of the second gear 208 meshes with the outer wall of the first gear 202. A motor 209 is installed on the outer wall of the GNSS road settlement monitoring instrument body 1. The output end of the motor 209 penetrates the mounting frame 207 and is fixedly connected to the bottom of the rotating rod.

[0025] The overall effect of Embodiment 1 is as follows: the cutting component 2 can efficiently remove obstacles around the road surface monitoring point, providing a clean environment for the accurate monitoring of the GNSS road surface settlement monitoring instrument body 1. Its flexible and adjustable cutting range and stable operation capability, through the meshing transmission of the first gear 202 in the mounting slot 201 and the second gear 208 on the mounting frame 207, when the motor 209 drives the rotating rod to rotate, can drive the first gear 202 to rotate smoothly, so that the ring-shaped fixed frame 203 and the cutting blade 206 form a circumferential cutting trajectory, expanding the operation coverage area. At the same time, the fixed... The first electric push rod 204 at the top of the frame 203 can extend and retract flexibly, pushing the moving block 205 and the cutting blade 206 to adjust their height vertically to accommodate obstacles of different heights. This structural design ensures the stability of the cutting blade 206 during rotation and allows for precise adjustment of the cutting position according to the actual obstacle conditions, avoiding unnecessary damage to the road surface. In addition, the multiple cutting blades 206 are distributed in a ring at equal intervals, forming a continuous cutting surface during rotation, improving the clearing efficiency, ensuring that the main body of the monitoring instrument is not disturbed by surrounding objects, and always maintaining accurate capture of road surface settlement differences.

[0026] Example 2, according to Figure 4 As shown, the fixing component 3 includes an annular frame 301 fixedly connected to the outer wall of the GNSS road settlement monitoring instrument body 1. Several sliding grooves 302 are annularly opened at the bottom of the outer wall of the GNSS road settlement monitoring instrument body 1. Several second electric push rods 303 are installed on the top of the annular frame 301. The output ends of the several second electric push rods 303 all penetrate the annular frame 301 and are fixedly connected to the lifting frame 304. The bottom of the several lifting frames 304 are fixedly connected to the stakes 305. The bottom of the GNSS road settlement monitoring instrument body 1 is fixedly connected to the base 4. Several mounting holes are annularly opened at the top of the base 4.

[0027] The overall effect of Embodiment 2 is as follows: The fixing component 3 provides a stable installation foundation for the equipment through multiple fixing methods, effectively resisting external environmental interference and ensuring the stability of monitoring data. The second electric push rod 303 on the ring frame 301 serves as the core driving component, which can push the lifting frame 304 to move vertically along the slide 302, so that the bottom stake 305 can be quickly inserted into the ground. The initial fixing is formed by the interlocking action of the stake 305 with the soil. The distribution design of the stake 305 can evenly distribute the weight of the equipment and prevent tilting caused by local settlement. At the same time, the base 4 at the bottom of the GNSS road settlement monitoring instrument body 1 is connected to the ground fixing component through the mounting hole to form a secondary reinforcement. Together with the stake 305, it forms a three-dimensional fixing structure, which greatly improves the overall anti-overturning ability of the equipment. The guiding effect of the slide 302 ensures that the lifting frame 304 does not deviate during the movement, and makes the insertion angle of the stake 305 consistent, further enhancing the fixing effect. It is suitable for different road conditions and can maintain the stability of the equipment position in various complex environments, providing a reliable benchmark for settlement monitoring and ensuring the accuracy and continuity of monitoring data.

[0028] The working principle of the entire device is as follows: When the road settlement difference monitoring device is working, the device is first stabilized on the road surface by the fixing component 3. In the fixing component 3, the second electric push rod 303 on the ring frame 301 is activated, and its output end pushes the lifting frame 304 to move along the slide groove 302 at the bottom of the outer wall of the GNSS road settlement monitor body 1, so that the stake 305 at the bottom of the lifting frame 304 is inserted into the ground. At the same time, the device can be further fixed by using the mounting holes on the base 4 at the bottom of the body, so as to ensure that the device remains stable during the monitoring process.

[0029] Subsequently, the cutting assembly 2 begins operation to remove obstacles around the road surface that may affect monitoring. After the motor 209 starts, its output end penetrates the mounting frame 207 to drive the rotating rod to rotate. The second gear 208 on the outer wall of the rotating rod rotates accordingly. Since the second gear 208 meshes with the first gear 202, the first gear 202 rotates in the mounting groove 201 through the bearing. The fixed frame 203 distributed in a ring on the top of the first gear 202 rotates together. The first electric push rod 204 on the fixed frame 203 can be extended and retracted, driving the moving block 205 and the cutting blade 206 on the outer wall to adjust their positions. During the rotation of the first gear 202, the cutting blade 206 performs cutting operations on obstacles around the road surface, ensuring that the GNSS road settlement monitoring instrument body 1 can smoothly carry out the monitoring of road settlement differences.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
