Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, and more specifically, to an underground power generation device and method based on metal mines. Background Technology

[0002] Metal mines are mines whose primary purpose is to extract metallic minerals. During underground operations, not only is a large amount of electricity required to support mining equipment and ventilation and lighting systems, but a continuous and stable energy supply is also needed to ensure the normal operation of critical processes such as hoisting and transportation, drainage and dust control, and safety monitoring. This high dependence on electricity creates a complex and energy-intensive electrical network within the mine. Therefore, how to achieve efficient and reliable power generation in the underground environment directly affects the mine's production efficiency, operating costs, and the safety of workers, making it a core technical problem that urgently needs to be solved in the sustainable development of mines.

[0003] According to patent document CN121408584A, a power generation device includes a generator body and a support structure. The support structure includes an extension drive component, an extension crossbar, support legs, guide components, and an extension guide plate. The extension drive component is fixed to the generator body. The extension crossbar is connected to the output end of the extension drive component and is driven by the extension drive component to perform vertical lifting and lowering movements. The support legs are provided with transverse slide bars, which are slidably installed on the extension crossbar along its extension direction. The guide components are fixed to the transverse slide bars. The extension guide plate is located on the generator body and has an inclined guide groove, in which the guide components are slidably fitted. By driving the vertical lifting and lowering movement of the extension crossbar with the extension drive component, and utilizing the constraint effect of the inclined guide groove of the extension guide plate on the guide components, the vertical linear motion is decomposed into the horizontal sliding of the support legs relative to the extension crossbar and the lifting and lowering movement of the support legs themselves, thus eliminating the need for a separate drive unit.

[0004] Power generation in metal mines typically relies on generators for electricity supply. However, during startup, the generator often generates severe and continuous mechanical vibrations. In the unique underground environment of metal mines, due to the complex geological structure, relatively enclosed space, and sensitive rock mass stability, these vibrations can induce a series of serious safety hazards. For example, strong vibration waves may be transmitted to the tunnel roof, causing the already loose rock strata or support structure to become unstable, leading to roof rock detachment or even localized roof collapse. At the same time, the vibrations may also cause other equipment, pipelines, or support components installed underground to shift, misalign, or loosen, thereby affecting the normal operation of the equipment and even causing equipment damage, pipeline leaks, or personnel injuries, posing a significant threat to safe production in the mine. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides an underground power generation device and method for metal mines. The technical problem to be solved by this invention is that during the startup process, the generator body often generates severe and continuous mechanical vibrations. In the special underground environment of metal mines, due to the complex geological structure, relatively enclosed space, and sensitive rock mass stability, such vibrations may induce a series of serious safety hazards. For example, strong vibration waves may be transmitted to the roof of the roadway, causing the originally loose rock strata or support structure to become unstable, leading to roof rock falling or even local roof collapse. At the same time, the vibration may also cause other equipment, pipelines, or support components installed underground to shift, misalign, or loosen their connections, thereby affecting the normal operation of the equipment, or even causing equipment damage, pipeline leakage, or personnel injury, posing a significant threat to the safe production of the mine.

[0013] As a further embodiment of the present invention: the generator support includes a top plate, and L-shaped expansion plates are fixedly connected to the left and right sides of the rear side of the top plate.

[0014] As a further embodiment of the present invention: L-shaped side connecting plates are fixedly connected to the left and right sides of the front side of the bottom of the top plate, and L-shaped motor placement plates are fixedly connected to the bottom of the inner side of the two L-shaped side connecting plates.

[0015] As a further embodiment of the present invention: the top support plate connecting frame includes two sets of inverted L-shaped bottom blocks, the bottom of the two sets of inverted L-shaped bottom blocks are fixedly connected to the four sides of the top of the top plate, the top of the two sets of inverted L-shaped bottom blocks are fixedly connected to uprights, the top of the inner sides of the two sets of uprights are fixedly connected to crossbars, the left and right sides of the top of the two crossbars are fixedly connected to concave guide blocks, and the bottom of the outer sides of the two sets of concave guide blocks are fixedly connected to elliptical cross plates.

[0016] As a further aspect of the present invention: a central connecting rod is fixedly connected to the middle of the inner side of each of the two elliptical horizontal plates; a rack guide plate is fixedly connected to the inner side of each of the two central connecting rods; columnar side rotating rods are rotatably connected to the left and right sides of the inner side of each of the two elliptical horizontal plates; gears are fixedly connected to the front and rear sides of the outer walls of each of the two columnar side rotating rods; rack uprights are slidably connected to the left and right sides of each of the two rack guide plates; and the outer sides of the left and right sets of rack uprights are connected to the outer walls of the left and right sets of gears.

[0017] As a further embodiment of the present invention: a rectangular lifting plate is fixedly connected to the bottom of the left and right sets of rack uprights, and an inverted L-shaped push-pull rod is fixedly connected to the middle left side of the rectangular lifting plate, and the bottom left side of the inverted L-shaped push-pull rod is fixedly connected to the top of the front side of the left support plate.

[0018] As a further embodiment of the present invention: both of the top support plates include arch support plates, and support plate sliders are fixedly connected to the front and rear sides of the inner side of the two arch support plates. The outer walls of the left and right sets of support plate sliders are slidably connected to the inner sides of the left and right sets of concave guide blocks. Rotating rods are rotatably connected to the inner bottom of the front and rear sets of support plate sliders. Second rotating rods are rotatably connected to the inner bottom of the front and rear sets of rotating rods. The inner walls of the left and right sets of second rotating rods on the side away from the rotating rods are fixedly connected to the front and rear sides of the outer walls of the two columnar side rotating rods.

[0019] In addition, the present invention also relates to a method for an underground power generation device based on a metal mine, comprising the following steps:

[0020] Step 1: Transport the entire power generation equipment to the target operating location pre-surveyed underground in the metal mine. After adjusting the placement of the device, fix the two side support plates to the base at the bottom of the mine, thus initially defining the location of the device.

[0021] Step 2: Activate the electric push rod. The electric push rod extends and drives the top plate push block to lift upward. The top plate push block pushes the top plate to move upward as a whole. As the top plate moves upward, it drives the two inverted L-shaped slide plates to slide upward along the L-shaped guide side plate and the vertical guide plate.

[0022] Step 3: The inverted L-shaped sliding plate moves upward, causing the lifting plate to rise synchronously. At the same time, it causes the two second abutment plates to move upward. After the second abutment plates move upward, they abut the corresponding side blocks to move inward. After the two abutment blocks are subjected to force, they cause the connected L-shaped side plates to slide inward along the columnar crossbar, simultaneously compressing the spring to store energy.

[0023] Step 4: As the L-shaped side plate moves inward, it drives the L-shaped expansion plate and the expansion side plate to move inward simultaneously, thereby driving the two arc-shaped positioning plates to gradually move inward, clamping and positioning the generator bottom sides placed in the positioning area, locking the generator's horizontal position, and preventing shaking and displacement during subsequent generator operation.

[0024] Step 5: During the upward lifting of the top plate, the top support plate connecting frame moves upward in sync. When the top support plate connecting frame moves upward, the inverted L-shaped push-pull rod remains fixed in position due to lateral support, so that the rectangular lifting plate and the rack and pinion upright move downward relative to the top support plate connecting frame.

[0025] Step Six: As the rack and pinion rod moves downward, the meshing drives the corresponding gear to rotate. The gear drives the coaxially fixed columnar side rotating rod to rotate synchronously. The rotation of the columnar side rotating rod causes the hinged second rotating rod to deflect. After the second rotating rod deflects, it pushes the hinged rotating rod to move to the top, which in turn drives the support plate slider to slide to the top along the concave guide block.

[0026] Step 7: After the transmission structures on both sides move synchronously, the two arch support plates expand outwards in sync, gradually pressing against the inner wall of the mine arch, and together with the side support plate at the bottom, the entire device is clamped and fixed from top to bottom, and the overall structure of the device is locked.

[0027] Step 8: Check the device's secure fixing and the generator's wiring connection status. After confirming that all structural conditions are normal, start the generator to carry out continuous power generation operations in the metal mine, providing a stable power supply for underground construction, lighting, and monitoring equipment.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention, by setting up a support frame and an arched support frame, achieves rapid clamping and positioning of the generator bottom, and simultaneously locks and fixes the entire device to the upper and lower rock walls of the mine. It can specifically solve a series of mine safety hazards caused by the severe vibration generated during generator start-up and operation as mentioned in the background art. It has the following beneficial effects: For the vibration problem of generator operation in underground metal mines, this invention achieves dual fixation of the generator and the entire device through a clamping and positioning structure and an upper and lower locking structure that can move synchronously. The clamping and positioning structure can directly clamp and limit the bottom of the generator body, restricting the shaking and displacement of the generator from the vibration source. It can significantly reduce the displacement amplitude caused by vibration during generator start-up and operation, reduce the energy transmitted outward from the source of vibration, and avoid the problem of vibration causing displacement, loosening, and connection failure of other equipment pipelines underground. It eliminates the safety hazards of equipment damage, pipeline leakage, and secondary personnel injury.

[0030] While clamping and fixing the generator, this invention can simultaneously tighten and fix the entire device to the mine arch and bottom, integrating the device itself with the mine rock wall into a stable whole. This further counteracts the vibration force transmitted from the generator to the device, preventing the device from shifting due to generator vibration and enhancing the overall structure's vibration resistance. At the same time, the two arch support structures directly press against the inner wall of the mine roadway arch, providing additional auxiliary support to the originally loose rock strata and support structure of the roadway roof. This counteracts the impact force of the generator vibration wave transmitted to the roof, reducing the probability of vibration-induced rock instability and preventing safety accidents such as roof falls and local roof collapses. This significantly improves the overall safety of underground power generation operations in metal mines.

[0031] The fixing and clamping and arch support actions of this invention can be completed simultaneously in one lifting action, without the need for multiple separate operations. It is suitable for the special environment of narrow working space and limited working conditions in metal mines. The operation process is simple and the fixing efficiency is high. While completing the quick installation and fixing, it will not occupy too much underground working space, which is suitable for the actual use needs of underground generator operation.

[0046] When power generation is required in a metal mine, the entire device is first installed in a suitable location underground. The two side support plates 12 are fixed to the bottom of the mine. When power generation is needed, the electric push rod 1114 is activated, causing the top plate push block 1122 to lift upwards. The top plate push block 1122 pushes the top plate 1121 upwards. Simultaneously, the upward movement of the top plate 1121 causes the two inverted L-shaped sliding plates 1123 to slide upwards along the L-shaped guide side plate 1118 and the vertical guide plate 1111. The upward movement of the inverted L-shaped sliding plates 1123 causes the lifting plate 1119 to lift upwards synchronously. The upward movement causes the two second abutment plates 1125 to move upward, which in turn pushes the two abutment blocks 11121 to move inward. After the two abutment blocks 11121 move inward under force, they will cause the L-shaped side plate 11120 to slide inward along the columnar crossbar 1113, simultaneously compressing the spring 1117 to store energy. As the L-shaped side plate 11120 moves, it also causes the side L-shaped expansion plate 11123 and expansion side plate 11124 to move inward, which in turn causes the two arc-shaped positioning plates 11125 to move inward, clamping and positioning the bottom sides of the generator 13 to prevent shaking and displacement during generator operation.

[0047] At the same time, the upward lifting of the top plate 1121 will synchronously drive the top support plate connecting frame 21 to move upward as a whole. During the upward movement of the top support plate connecting frame 21, the position of the inverted L-shaped push-pull rod 2112 remains fixed, which will drive the rectangular lifting plate 2111 and the rack and pinion rod 2110 to move downward relative to each other. The downward movement of the rack and pinion rod 2110 meshes with the gear 218 to rotate. The gear 218 drives the columnar side rotating rod 217 to rotate synchronously. The rotation of the columnar side rotating rod 217 drives the second rotating rod 224 to deflect. The second rotating rod 224 pushes the rotating rod 223 to move upward, which in turn drives the support plate slider 222 to slide upward along the concave guide block 214. Finally, the two arch support plates 221 synchronously unfold outward, pressing against the inner wall of the mine arch, completing the overall upper and lower fixation of the device. At this time, the generator can be started to carry out underground power generation operations.

[0048] When the power generation operation is completed and the device needs to be disassembled and moved, the control electric push rod 1114 drives the top plate push block 1122 to return to its original position downwards, the spring 1117 releases the stored energy and drives the L-shaped side plate 11120 to return to its original position outwards, the arc-shaped positioning plate 11125 simultaneously releases the clamp on the generator 13, and at the same time the top support plate connecting frame 21 moves downwards with the top plate 1121, the rack and pinion rod 2110 moves upwards relative to the meshing gear 218 and rotates in the opposite direction, driving the columnar side rotating rod 217 to rotate in the opposite direction, pulling the two arch support plates 221 to retract simultaneously, releasing the clamping on the inner wall of the arch, so that the device can be disassembled as a whole and moved to other working positions to complete the operation adjustment.

[0049] In addition, the present invention also relates to a method for an underground power generation device based on a metal mine, comprising the following steps:

[0050] Step 1: Transport the entire power generation equipment to the target operating location pre-surveyed underground in the metal mine. After adjusting the placement of the device, fix the two side support plates 12 to the base at the bottom of the mine, thus initially defining the position of the device.

[0051] Step 2: Activate the electric push rod 1114. The electric push rod 1114 extends and drives the top plate push block 1122 to rise. The top plate push block 1122 pushes the top plate 1121 to move upward as a whole. While the top plate 1121 moves upward, it drives the two inverted L-shaped slide plates 1123 to slide upward along the L-shaped guide side plate 1118 and the vertical guide plate 1111.

[0052] Step 3: The inverted L-shaped sliding plate 1123 moves upward, causing the lifting plate 1119 to rise synchronously. At the same time, it causes the two second abutment plates 1125 to move upward. After the second abutment plates 1125 move upward, they abut against the corresponding side block 11121 and move inward. After the two abutment blocks 11121 are subjected to force, they cause the connected L-shaped side plate 11120 to slide inward along the columnar crossbar 1113, and simultaneously compress the spring 1117 to store energy.

[0053] Step 4: As the L-shaped side plate 11120 moves inward, it drives the L-shaped expansion and contraction plate 11123 and the expansion and contraction plate 11124 to move inward simultaneously, thereby driving the two arc-shaped positioning plates 11125 to gradually move inward, clamping and positioning the generator 13 placed in the positioning area on both sides of the bottom, locking the horizontal position of the generator 13, and preventing shaking and displacement during subsequent generator operation;

[0054] Step 5: During the upward lifting of the top plate 1121, the top support plate connecting frame 21 is moved upward as a whole. When the top support plate connecting frame 21 moves upward, the inverted L-shaped push-pull rod 2112 is fixed by lateral support, so that the rectangular lifting plate 2111 and the rack and pinion rod 2110 move downward relative to the top support plate connecting frame 21.

[0055] Step Six: During the downward movement of the rack and pinion rod 2110, the meshing drives the corresponding gear 218 to rotate. The gear 218 drives the coaxially fixed columnar side rotating rod 217 to rotate synchronously. The rotation of the columnar side rotating rod 217 drives the hinged second rotating rod 224 to deflect. After the second rotating rod 224 deflects, it pushes the hinged rotating rod 223 to move to the top, thereby driving the support plate slider 222 to slide to the top along the concave guide block 214.

[0056] Step 7: After the transmission structures on both sides move synchronously, the two arch support plates 221 expand outwards in sync, gradually pressing against the inner wall of the mine arch, and together with the side support plate 12 at the bottom, the entire device is clamped and fixed from top to bottom, and the overall structure of the device is locked.

[0057] Step 8: Check the device's secure fixing and the connection status of generator 13. After confirming that all structural conditions are normal, start generator 13 to carry out continuous power generation operations in the metal mine, providing a stable power supply for underground construction, lighting, and monitoring equipment.

[0058] Working principle of this invention: When power generation is required in a metal mine, the entire device is first installed in a suitable location underground. The two side support plates 12 are fixed to the bottom of the mine. When power generation is needed, the electric push rod 1114 is activated, causing the top plate push block 1122 to lift upwards. The top plate push block 1122 pushes the top plate 1121 upwards. Simultaneously, as the top plate 1121 moves upwards, it causes the two inverted L-shaped sliding plates 1123 to slide upwards along the L-shaped guide side plate 1118 and the vertical guide plate 1111. The L-shaped sliding plate 1123 moves upward, causing the lifting plate 1119 to rise synchronously. The two inverted L-shaped sliding plates 1123 move upward, which in turn causes the two second abutment plates 1125 to move upward, thus pushing the two abutment blocks 11121 inward. After the two abutment blocks 11121 move inward under force, they cause the L-shaped side plate 11120 to slide inward along the columnar crossbar 1113, simultaneously compressing and storing energy in the spring 1117. As the L-shaped side plate 11120 moves, it also drives the side L-shaped expansion and contraction plates 11123 and... The retractable side plate 11124 moves inward synchronously, thereby causing the two arc-shaped positioning plates 11125 to move inward, clamping and positioning the bottom sides of the generator 13 to prevent shaking or displacement during generator operation. Simultaneously, the top plate 1121 rises upward, synchronously causing the top support plate connecting frame 21 to move upward as a whole. During the upward movement of the top support plate connecting frame 21, the inverted L-shaped push-pull rod 2112 remains fixed, causing the rectangular lifting plate 2111 and the rack and pinion column 2110 to move downward relative to each other. The vertical rod 2110 moves downward and engages with the gear 218, which in turn drives the columnar side rotating rod 217 to rotate synchronously. The rotation of the columnar side rotating rod 217 causes the second rotating rod 224 to deflect. The second rotating rod 224 pushes the rotating rod 223 to move upward, which in turn drives the support plate slider 222 to slide upward along the concave guide block 214. Finally, the two arch support plates 221 expand outward synchronously, pressing against the inner wall of the mine arch, completing the overall upper and lower fixation of the device. At this time, the generator can be started to carry out underground power generation operations.

10. A method for an underground power generation device based on a metal mine, as described in claim 9, characterized in that: Includes the following steps: Step 1: Transport the power generation equipment as a whole to the target operation location pre-surveyed in the underground of the metal mine. After adjusting the placement of the device, fix the two side support plates (12) to the base at the bottom of the mine to initially complete the position limitation of the device. Step 2: Activate the electric push rod (1114). The electric push rod (1114) extends and drives the top plate push block (1122) to rise. The top plate push block (1122) pushes the top plate (1121) to move upward as a whole. While the top plate (1121) moves upward, it drives the two inverted L-shaped slide plates (1123) to slide upward along the L-shaped guide side plate (1118) and the vertical guide plate (1111). Step 3: The inverted L-shaped sliding plate (1123) moves upward, causing the lifting plate (1119) to rise synchronously. At the same time, it causes the two second abutment plates (1125) to move upward. After the second abutment plates (1125) move upward, they abut against the corresponding side block (11121) and move inward. After the two abutment plates (11121) are subjected to force, they cause the connected L-shaped side plate (11120) to slide inward along the columnar crossbar (1113), and simultaneously compress the spring (1117) to store energy. Step 4: As the L-shaped side plate (11120) moves inward, it drives the side L-shaped expansion plate (11123) and expansion side plate (11124) to move inward simultaneously, thereby driving the two arc-shaped positioning plates (11125) to gradually move inward, clamping and positioning the generator (13) on both sides of the bottom of the positioning area, locking the horizontal position of the generator (13) and preventing shaking and displacement during subsequent generator operation; Step 5: During the upward lifting of the top plate (1121), the top support plate connecting frame (21) is moved upward as a whole. When the top support plate connecting frame (21) moves upward, the inverted L-shaped push-pull rod (2112) is fixed in position by lateral support, so that the rectangular lifting plate (2111) and the rack and pinion rod (2110) move downward relative to the top support plate connecting frame (21). Step 6: During the downward movement of the rack and pinion rod (2110), the meshing drives the corresponding gear (218) to rotate. The gear (218) drives the coaxially fixed columnar side rotating rod (217) to rotate synchronously. The rotation of the columnar side rotating rod (217) drives the hinged second rotating rod (224) to deflect. After the second rotating rod (224) deflects, it pushes the hinged rotating rod (223) to move to the top, thereby driving the support plate slider (222) to slide to the top along the concave guide block (214). Step 7: After the transmission structures on both sides move synchronously, the two arch support plates (221) expand outwards synchronously, gradually pressing against the inner wall of the mine arch, and together with the side support plate (12) at the bottom, the device is clamped and fixed from top to bottom, and the overall structure of the device is locked. Step 8: Check the device's secure fixing and the generator (13) line connection status. After confirming that all structural statuses are normal, start the generator (13) to carry out continuous power generation operations in the metal mine, providing a stable power supply for underground construction, lighting, and monitoring equipment.
