[0002] The GNSS slope monitoring and early warning device is a high-precision slope monitoring device based on Global Navigation Satellite System (GNSS) technology. It plays an important role in the field of slope safety monitoring. The GNSS slope monitoring and early warning device uses GNSS technology to monitor displacement. The GNSS system includes multiple satellites that continuously transmit signals to the ground. After receiving these signals, the GNSS receiver in the device can determine the precise location of the receiving point by calculating the signal propagation time and satellite position. By recording and updating this location information in real time, the displacement changes of the slope can be monitored.

[0003] However, traditional GNSS slope monitoring and early warning devices are installed by fixing the mounting base at the bottom of the mounting column to the concrete base poured on the ground with bolts. When the device malfunctions and needs to be disassembled and replaced, the bolts on the mounting base need to be removed one by one, and the cabinet needs to be installed on the mounting column with clamps.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, a slope monitoring and early warning device for open-pit coal mines includes a mounting column 1. A cabinet 3 is mounted on the top of the mounting column 1 via a mounting structure 2. The mounting structure 2 includes a protrusion 202. The top of the mounting column 1 is fixedly connected to the protrusion 202, and a fixing sleeve 201 is engaged with the protrusion 202. A base plate 4 is fixedly connected to the bottom of the cabinet 3. The fixing sleeve 201 is fixedly connected to the middle of the base plate 4. A locking block 204 is slidably connected to the fixing sleeve 201. A locking groove 203 is provided on the protrusion 202. The end of the locking block 204 engages with the locking groove 203. A GNSS receiver 5 is mounted on the top of the cabinet 3.

[0022] As a technical optimization of this utility model, the fixing sleeve 201 has a rectangular structure and the protrusion 202 has a rectangular structure, so that the fixing sleeve 201 and the protrusion 202 are more stably engaged.

[0023] As a technical optimization of this utility model, the locking block 204 has an overall "L" shape structure, and the end of the locking block 204 is provided with a bevel structure. A tension spring 205 is fixedly connected between the fixing sleeve 201 and the locking block 204. One end of the tension spring 205 is fixedly connected to the fixing sleeve 201, and the other end of the tension spring 205 is fixedly connected to the locking block 204. A guide rod 206 is fixedly connected to the fixing sleeve 201, and the locking block 204 is slidably connected. Connected to guide rod 206; when installing cabinet 3, lift cabinet 3, align the fixing sleeve 201 at the bottom of cabinet 3 with the protrusion 202 on mounting post 1, and then move cabinet 3 downwards so that fixing sleeve 201 engages with protrusion 202. Since the end of locking block 204 has a beveled structure, it guides the sliding of locking block 204. During the engagement of fixing sleeve 201 and protrusion 202, protrusion 202 slides against locking block 204 outwards from fixing sleeve 201, locking... Block 204 causes the tension spring 205 to extend. When the slot 203 on the protrusion 202 aligns with the block 204, the tension spring 205 resets, causing the block 204 to engage in the slot 203. This prevents the fixing sleeve 201 and the cabinet 3 from sliding upwards, allowing the cabinet 3 to be quickly installed on the mounting post 1. The operation is flexible and convenient, and the installation is stable. When the device needs to be disassembled and replaced, the protective door 6 is rotated so that it no longer obstructs the internal components of the cabinet 3. Then, the block 204 is pulled, causing it to slide outwards from the fixing sleeve 201 on the guide rod 206. This prevents the block 204 from engaging with the slot 203. The guide rod 206 guides the block 204, making its sliding more stable. Then, the cabinet 3 is lifted upwards, causing the fixing sleeve 201 to move upwards. This prevents the fixing sleeve 201 from engaging with the protrusion 202, allowing the cabinet 3 and other components on it to be quickly disassembled.

[0024] As a technical optimization of this utility model, a protective door 6 is rotatably connected to the cabinet 3, and a fixing seat 7 is fixedly connected to the bottom end of the mounting column 1; the protective door 6 has a good protective effect on the internal components of the cabinet 3, and the mounting column 1 is installed in a designated position through the fixing seat 7.

[0025] As a technical optimization of this utility model, a support frame 9 is fixedly connected to the cabinet 3, a photovoltaic panel 8 is installed on the support frame 9, and a connecting rod 10 is fixedly connected to the support frame 9. The end of the connecting rod 10 is fixedly connected to the back of the photovoltaic panel 8. The support frame 9 is installed on the back of the cabinet 3 by bolts. Then, the photovoltaic panel 8 is placed on the support frame 9 so that the bottom end of the photovoltaic panel 8 abuts against the end of the support frame 9, thereby making the photovoltaic panel 8 stable. Then, the photovoltaic panel 8 is connected to the connecting rod 10 by bolts, and then the support frame 9 is connected to the photovoltaic panel 8 by bolts, thereby making the installation of the photovoltaic panel 8 more secure.

[0026] In use, the GNSS receiver 5 is first bolted to the top of the cabinet 3. Then, the support frame 9 is bolted to the back of the cabinet 3. Next, the photovoltaic panel 8 is placed on the support frame 9, with its bottom end touching the end of the support frame 9 to ensure stability. The photovoltaic panel 8 is then bolted to the connecting rod 10, and the support frame 9 is bolted to the photovoltaic panel 8 for a more secure installation. The fixing base 7 is bolted to the concrete base poured on the ground, fixing the mounting column 1 in the designated position. When installing the cabinet 3, the cabinet 3 is lifted, aligning the fixing sleeve 201 at the bottom of the cabinet 3 with the protrusion 202 on the mounting column 1. The cabinet 3 is then moved downwards, causing the fixing sleeve 201 to engage with the protrusion 202. Because the end of the locking block 204 has a beveled structure, it guides the sliding of the locking block 204. During the engagement of the fixing sleeve 201 and the protrusion 202, the protrusion 202 abuts against the locking block. 204 slides outward from the fixed sleeve 201. The locking block 204 causes the tension spring 205 to extend. When the locking groove 203 on the protrusion 202 aligns with the locking block 204, the tension spring 205 resets, causing the locking block 204 to engage in the locking groove 203. This prevents the fixed sleeve 201 and the cabinet 3 from sliding upward, thus quickly installing the cabinet 3 onto the mounting post 1. The operation is flexible and convenient, and the installation is stable. When the device needs to be disassembled and replaced, the protective door 6 is rotated so that the protective door 6 no longer obstructs the internal components of the cabinet 3. The component is blocked, and then the locking block 204 is pulled, causing the locking block 204 to slide outward on the guide rod 206 towards the fixed sleeve 201, so that the locking block 204 is no longer engaged with the slot 203. The guide rod 206 guides the locking block 204, making the sliding of the locking block 204 more stable. Then the cabinet 3 is lifted upward, and the cabinet 3 drives the fixed sleeve 201 to move upward, so that the fixed sleeve 201 is no longer engaged with the protrusion 202, thereby quickly disassembling the cabinet 3 and other components on the cabinet 3.
