A support structure 7 is installed inside the fixing column 5; when the mounting base 1 is inclined after installation, rotate the worm 804. The worm 804 drives the worm gear 803 to rotate. The worm gear 803 drives the rotating shaft 802 to rotate. While the rotating shaft 802 rotates, it drives the connecting rod 805 to rotate. Continuously rotate the worm 804 until the connecting rod 805 is adjusted to an angle perpendicular to the ground, and then stop rotating the worm 804, so as to fix the connecting rod 805, thereby facilitating the adjustment of the angle of the warning device, making the installation more convenient and flexible, and improving the construction efficiency.

[0023] As a technical optimization scheme of the present invention, a protective box 801 is fixedly connected to one side of the mounting base 1.

The two sliders 705 are slidably connected to the fixed column 5. Two second clamping blocks 703 are slidably connected to both sides of the fixed column 5. The two second clamping blocks 703 are respectively fixedly connected to the bottom ends of the two sliders 705 by bolts. The threads at both ends of the lead screw 702 are opposite. The two sliders 705 are symmetrically distributed about the center of the fixed column 5. The end of the lead screw 702 is fixedly connected to a knob 701. A groove 704 is formed in the knob 701. The top end of the fixed column 5 is provided with a chassis 6. Pass the second clamping block 703 through the outer wall of the fixed column 5, and then use bolts to fixedly connect the two second clamping blocks 703 to the sliders 705 respectively. Then bury the fixed column 5 into the ground so that the bottom end of the chassis 6 abuts against the ground. Then rotate the knob 701, or insert a hexagonal wrench into the groove 704 and then rotate the hexagonal wrench to make the knob 701 rotate. When the knob 701 rotates, it drives the lead screw 702 to rotate. Since the threads at both ends of the lead screw 702 are opposite, the lead screw 702 drives the two sliders 705 to slide in opposite directions. The two sliders 705 drive the two second clamping blocks 703 to move towards the outside of the fixed column 5 until the second clamping blocks 703 are inserted into the soil outside the fixed column 5, thereby playing a supporting role for the fixed column 5 and making the installation of the fixed column 5 more stable and firm.

When the card slot 306 on the inner wall of the warning column body 2 is aligned with the first card block 303, the first card block 303 loses its resistance, and the spring 304 resets and drives the first card block 303 to slide toward the outside of the connecting rod 805 until it is engaged in the card slot 306, thereby realizing the rapid installation of the warning column body 2. When the warning column body 2 needs to be disassembled for maintenance, the push rod 301 is passed through the mounting seat 1 and The connecting rod 805 is fixedly connected to the bottom end of the first block 303 by bolts, and then the connecting plate 302 at the end of the push rod 301 is pushed. The connecting plate 302 drives the push rod 301 to slide toward the inside of the connecting rod 805, and at the same time drives the first block 303 to slide on the first guide rod 305 in the direction away from the slot 306 until the first block 303 slides out of the slot 306, thereby facilitating the rapid disassembly, maintenance or replacement of the warning column body 2. When reinstalling, there is no need to replace the fixing column 5 and the mounting base 1, which improves the installation efficiency and saves the installation cost.

[0027] As a technical optimization solution of the utility model, the end of the push rod 301 facing the outside of the mounting seat 1 is fixedly connected with a connecting plate 302, and the first clamping block 303 is in an "L"-shaped structure; the setting of the connecting plate 302 facilitates the operation of the push rod 301, making the operation more comfortable.

[0028] As a technical optimization solution of the utility model, a solar panel 4 is installed at the top of the warning post body 2, a warning tape 10 is wound around the outside of the warning post body 2, and a plurality of warning lights 9 are installed on the warning post body 2; a solar panel 4 is installed at the top of the warning post body 2.

Warning lights 9 and warning tapes 10 are installed on the warning post body 2, so that the warning post body 2 can play a good warning and reminder role, making coal mine production safer.

[0029] When the utility model is in use, first, the second clamping block 703 is passed through the outer wall of the fixed column 5, and then the two second clamping blocks 703 are fixedly connected to the slide bar 705 by bolts. Then, the fixed column 5 is buried underground so that the bottom end of the chassis 6 abuts against the ground. Then, the knob 701 is rotated, or a hexagonal wrench is inserted into the groove 704 and then the hexagonal wrench is rotated to rotate the knob 701. While the knob 701 rotates, the lead screw 702 is driven to rotate. Since the threads at both ends of the lead screw 702 are opposite, the lead screw 702 drives the two slide bars 705 to slide in opposite directions. The two slide bars 705 drive the two second clamping blocks 703 to move towards the outside of the fixed column 5 until the second clamping blocks 703 are inserted into the soil outside the fixed column 5, thereby playing a supporting role for the fixed column 5 and making the installation of the fixed column 5 more stable and firm. Then, the mounting seat 1 is threadedly connected to the top end of the fixed column 5. When the connecting rod 805 is inclined to the ground, the worm 804 is rotated. The worm 804 drives the worm gear 803 to rotate, and the worm gear 803 drives the rotating shaft 802 to rotate. While the rotating shaft 802 rotates, the connecting rod 805 is driven to rotate. The worm 804 is continuously rotated until the connecting rod 805 is adjusted to an angle perpendicular to the ground and then the rotation of the worm 804 is stopped, thereby fixing the connecting rod 805, and further facilitating the adjustment of the angle of the warning device, making the installation more convenient and flexible, and improving the construction efficiency. Then, the warning column body 2 is aligned with the connecting rod 805, and the warning column body 2 is moved downward so that the warning column body 2 is engaged with the connecting rod 805 until the bottom end of the warning column body 2 abuts against the mounting seat 1. Then, the warning column body 2 is rotated. The inner wall of the warning column body 2 abuts against the first clamping block 303 and moves towards the inside of the connecting rod 805. The first clamping block 303 slides on the first guide rod 305. At the same time, the first clamping block 303 abuts against the spring 304 to contract the spring 304. The warning column body 2 is continuously rotated. When the clamping groove 306 on the inner wall of the warning column body 2 is aligned with the first clamping block 303, the first clamping block 303 loses the abutting force, and the spring 304 resets to drive the first clamping block 303 to slide towards the outside of the connecting rod 805 until it is engaged in the clamping groove 306, thereby realizing the rapid installation of the warning column body 2. When the warning column body 2 needs to be disassembled and repaired, the push rod 301 is passed through the mounting seat 1 and the connecting rod 805 and fixedly connected to the bottom end of the first clamping block 303 by bolts. Then, the connecting plate 302 at the end of the push rod 301 is pushed. The connecting plate 302 drives the push rod 301 to slide towards the inside of the connecting rod 805, and at the same time drives the first clamping block 303 to slide on the first guide rod 305 in a direction away from the clamping groove 306 until the first clamping block 303 slides out of the clamping groove 306, thereby facilitating the rapid disassembly, repair or replacement of the warning column body 2. When installing again, there is no need to replace the fixed column 5 and the mounting seat 1, which improves the installation efficiency and saves the installation cost at the same time;A solar panel 4 is installed at the top of the warning post body 2. When the warning post body 2 is installed in an open-pit mine, it can provide power support through the solar panel 4, making the warning post body 2 more environmentally friendly and energy-saving. A warning light 9 and a warning tape 10 are installed on the warning post body 2, enabling the warning post body 2 to play a good warning and reminder role and making coal mine production safer.
