Description

Technical Field

[0001] This utility model belongs to the field of open-pit mine slope stability early warning technology, and specifically relates to an open-pit mine slope stability early warning device. Background Technology

[0002] The open-pit mine slope stability early warning device is an automated monitoring system built on multi-source sensing technology and intelligent algorithms. It is mainly used to sense slope deformation in real time, predict instability risks and trigger early warnings in a timely manner to ensure safe production in the mine.

[0003] A utility model patent with patent authorization announcement number CN221399126U discloses an open-pit mine slope stability detection device, including a support column, an electrical control box on the outside of the support column, an extension frame on the outside of the support column, a solar panel on the top of the extension frame, a connecting block rotatably connected to the inside of the extension frame at the bottom of the solar panel, an adjustment mechanism movably connected to the extension frame and located below the connecting block at the bottom of the solar panel, a fixed base on the outside of the support column, a displacement sensor mounting hole inside the fixed base, a landslide detection plate at the bottom of the fixed base, and an angle sensor between the fixed base and the landslide detection plate.

[0004] However, existing open-pit mine slope stability early warning devices also have certain shortcomings. Most existing open-pit mine slope stability early warning devices use photovoltaic panels with fixed orientations for photoelectric conversion. Since the angle of direct sunlight changes over time, this will cause poor photoelectric conversion efficiency of the photovoltaic panels. Summary of the Invention

[0005] The purpose of this invention is to provide an early warning device for the stability of open-pit mine slopes, which solves the problem that existing early warning devices for the stability of open-pit mine slopes mostly use photovoltaic panels with fixed orientations for photoelectric conversion. Since the angle of direct sunlight changes over time, this results in poor photoelectric conversion efficiency of the photovoltaic panels.

[0006] To achieve the above objectives, this utility model provides an early warning device for the stability of open-pit mine slopes, comprising a base, a fastening bolt movably connected to the inner wall of the base, a fixed rod fixedly connected to the upper middle part of the base, a rain sensor fixedly installed at the upper end of the fixed rod, a support rod fixedly connected to the middle part of the fixed rod, a GNSS displacement monitor fixedly installed on the lower left side of the support rod, a support frame fixedly connected to the right end of the support rod, an auxiliary mechanism provided on the support frame, a cable provided on the outer side of the fixed rod, a support plate fixedly sleeved on the outer side of the fixed rod, the support plate contacting the cable, a guide rod slidably connected to the inner wall of the support rod, a clamping plate fixedly connected to the lower end of the guide rod, and an end sleeve fixedly sleeved on the outer side of the clamping plate.

[0007] The principle of this utility model is as follows: by pushing the clamping plate upward along the surface of the fixed rod and driving the guide rod to slide along the inner wall of the support rod, the spring is deformed. Then, the long cable is wrapped around the outside of the fixed rod, so that the cable contacts the support plate. The clamping plate is then released, so that the spring returns to its original deformation, thereby pushing the clamping plate downward along the surface of the fixed rod, so that the clamping plate contacts the cable. Under the action of the support plate and the clamping plate, the cable can be limited and used, and then the cable can be stored and used.

[0008] Photovoltaic panels enable photoelectric conversion. Driven by a motor, the photovoltaic panels can rotate, and their angle can be adjusted adaptively. When the photovoltaic panels rotate, the driven end can also rotate. Under the pressure of the inner wall of the slot, the locking block can be moved, causing the telescopic rod to slide along the inner wall of the fixed ear and the end plate to slide along the guide plate surface to ensure stable movement of the locking block. When the telescopic rod moves, the second spring can deform, ultimately causing the locking block to disengage from the slot.

[0009] Under the action of force, the locking block slides along the surface of the driven end. When the locking block slides into the next slot, the spring returns to its original deformation, pushing the locking block into the slot to limit the driven end. This counteracts the centrifugal force generated by the motor, photovoltaic panel and other components, thereby stabilizing the photovoltaic panel.

[0010] The beneficial effects of this utility model are as follows: This solution winds the cables used by devices such as rain sensors and GNSS displacement monitors around the outside of a fixed rod. The support plate supports and limits the cables, and with the help of clamps and springs, the cables can be clamped, thus storing long cables. The photovoltaic panel enables photoelectric conversion, and the angle of the photovoltaic panel can be adaptively adjusted under the drive of the motor. The driven end can be limited by the slots, blocks, and springs, thereby positioning the deflection angle of the photovoltaic panel and improving its stability.

[0011] Furthermore, two guide rods are provided, which are symmetrically distributed on the clamping plate. The clamping plate can be moved and guided by the guide rods.

[0012] Furthermore, the clamp is slidably connected to the fixing rod, and the clamp is in contact with the cable. The clamp can limit the cable's movement.

[0013] Furthermore, a spring is fixedly connected to the upper end of the end sleeve, and the other end of the spring is welded to the support rod. The end sleeve can be connected and used by means of the spring.

[0014] Furthermore, the auxiliary mechanism includes a motor. The motor is fixedly installed on the back of the support frame. The output shaft of the motor is rotatably connected to the support frame. A photovoltaic panel is fixedly installed on the output shaft of the motor. A driven end is fixedly connected to the front of the photovoltaic panel. The driven end is rotatably connected to the support frame. A slot is formed on the surface of the driven end. A fixing ear is fixedly connected to the front of the support frame and to the left of the driven end. A telescopic rod is slidably connected to the inner wall of the fixing ear. A locking block is fixedly connected to the right end of the telescopic rod. The locking block is slidably connected to the slot. An end plate is fixedly connected to the left end of the telescopic rod. A second spring is provided on the outer side of the telescopic rod. One end of the second spring is welded to the end plate, and the other end of the second spring is welded to the fixing ear. Driven by the motor, the photovoltaic panel can be rotated, and the angle of the photovoltaic panel can be adaptively adjusted. Under the action of the slot, locking block, and other structures, the driven end can be limited, thereby positioning the photovoltaic panel for use.

[0015] Furthermore, multiple card slots are provided, and the multiple card slots are arranged in a circular array on the driven end. The arrangement of the card slots facilitates their use in conjunction with the card block for limiting positioning.

[0016] Furthermore, a guide plate is fixedly connected to the left end of the fixed ear. The guide plate is slidably connected to the end plate. The end plate can be moved and guided by the guide plate. Attached Figure Description

Detailed Implementation

[0023] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides an early warning device for the stability of an open-pit mine slope, including a base 1. A fastening bolt 2 is movably connected to the inner wall of the base 1. A fixing rod 3 is fixedly connected to the middle of the upper end of the base 1. A rain sensor 4 is fixedly installed at the upper end of the fixing rod 3. A support rod 5 is fixedly connected to the middle of the fixing rod 3. A GNSS displacement monitor 6 is fixedly installed on the left side of the lower end of the support rod 5. A support frame 7 is fixedly connected to the right end of the support rod 5. A cable 9 is provided on the outside of the fixing rod 3. A support plate 10 is fixedly sleeved on the outside of the fixing rod 3. The support plate 10 is in contact with the cable 9. A guide rod 11 is slidably connected to the inner wall of the support rod 5. A clamping plate 12 is fixedly connected to the lower end of the guide rod 11. An end sleeve 13 is fixedly sleeved on the outside of the clamping plate 12.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, there are two guide rods 11, which are symmetrically distributed on the clamping plate 12. The guide rods 11 can guide the movement of the clamping plate 12. The clamping plate 12 is slidably connected to the fixing rod 3 and contacts the cable 9. The clamping plate 12 can limit the use of the cable 9. A spring 14 is fixedly connected to the upper end of the end sleeve 13. The other end of the spring 14 is welded to the support rod 5. The end sleeve 13 can be connected and used through the spring 14.

[0025] like Figure 1 , Figure 2 , Figure 4As shown, an auxiliary mechanism 8 is provided on the support frame 7. The auxiliary mechanism 8 includes a motor 81. The motor 81 is fixedly installed on the back of the support frame 7. The output shaft of the motor 81 is rotatably connected to the support frame 7. A photovoltaic panel 82 is fixedly installed on the output shaft of the motor 81. A driven end 83 is fixedly connected to the front of the photovoltaic panel 82. The driven end 83 is rotatably connected to the support frame 7. A slot 84 is provided on the surface of the driven end 83. A fixing ear 85 is fixedly connected to the front of the support frame 7 and to the left of the driven end 83. A telescopic rod 86 is slidably connected to the inner wall of the fixing ear 85. A locking block 87 is fixedly connected to the right end of the telescopic rod 86, and the locking block 87 is slidably connected to the slot 84. An end plate 88 is fixedly connected to the left end of the telescopic rod 86, and a second spring 890 is provided on the outside of the telescopic rod 86. One end of the second spring 890 is welded to the end plate 88, and the other end of the second spring 890 is welded to the fixing ear 85. Driven by the motor 81, the photovoltaic panel 82 can be rotated to adapt the angle of the photovoltaic panel 82. Under the action of the slot 84, locking block 87 and other structures, the driven end 83 can be limited, thereby positioning the photovoltaic panel 82 for use.

[0026] like Figure 1 , Figure 2 , Figure 4 As shown, multiple slots 84 are provided, and the multiple slots 84 are arranged in a ring array on the driven end 83. The slots 84 are designed to facilitate the use of the locking block 87 for limiting. A guide plate 89 is fixedly connected to the left end of the fixing ear 85. The guide plate 89 is slidably connected to the end plate 88. The guide plate 89 is designed to guide the movement of the end plate 88.

[0027] The specific implementation process of this utility model is as follows: By pushing the clamping plate 12 upward along the surface of the fixed rod 3 and driving the guide rod 11 to slide along the inner wall of the support rod 5, the spring 14 deforms. Then, the long cable 9 is wrapped around the outside of the fixed rod 3 so that the cable 9 contacts the support plate 10. The clamping plate 12 is then released so that the spring 14 returns to its original shape, thereby pushing the clamping plate 12 downward along the surface of the fixed rod 3 so that the clamping plate 12 contacts the cable 9. Under the action of the support plate 10 and the clamping plate 12, the cable 9 can be limited and used, and then the cable 9 can be stored and used.

[0028] Photovoltaic panel 82 can be used for photoelectric conversion. Driven by motor 81, photovoltaic panel 82 can be rotated to adapt the angle of photovoltaic panel 82. When photovoltaic panel 82 rotates, it can drive driven end 83 to rotate. Under the pressure of the inner wall of slot 84, it can push block 87 to move, so as to drive telescopic rod 86 to slide along the inner wall of fixed ear 85 and drive end plate 88 to slide along the surface of guide plate 89 to ensure stable movement of block 87. When telescopic rod 86 moves, spring 890 can deform, and finally block 87 is disengaged from slot 84.

[0029] Under the action of force, the locking block 87 slides along the surface of the driven end 83. When the locking block 87 slides into the next slot 84, the spring 890 restores its deformation to push the locking block 87 into the slot 84, limit the driven end 83, and thus counteract the rotational centrifugal force generated by components such as the motor 81 and the photovoltaic panel 82, thereby stabilizing the photovoltaic panel 82.

[0030] This solution involves winding the cable 9 used by devices such as the rain sensor 4 and the GNSS displacement monitor 6 around the outside of the fixed rod 3. With the support plate 10, the cable 9 can be supported and limited. With the help of the clamping plate 12, spring 14 and other structures, the cable 9 can be clamped and stored. The photovoltaic panel 82 can be used for photoelectric conversion. Driven by the motor 81, the illumination angle of the photovoltaic panel 82 can be adaptively adjusted. With the help of the slot 84, the locking block 87, spring 890 and other structures, the driven end 83 can be limited, thereby positioning the deflection angle of the photovoltaic panel 82 and improving the stability of the photovoltaic panel 82.
