[0017] 1. The robot inspection path cleaning device for gas-fired power plants described in this invention, after the first cleaning mechanism cleans the accumulated dirt on the cleaning shovel, can achieve self-cleaning through the linkage of the first drive mechanism. The first motor drives the first sprocket, the second sprocket and the first chain transmission, and through the meshing of two gears, drives the crank to swing, so that the first and second sliders slide stably back and forth in the cross support frame, causing the two cleaning shovels to contact and move relative to each other, scraping off the accumulated dirt.

[0018] 2. The robot inspection path cleaning device for gas-fired power plants described in this invention features a second drive mechanism that achieves efficient cleaning and self-cleaning in tandem through dual-path power transmission. One path drives the brush plate to rotate, sweeping away residual dirt on the ground and cleaning shovel. A spring assembly pushes the contact block through elastic extension and contraction, ensuring that the brush bristles always fit tightly against the ground, guaranteeing cleaning effectiveness under different terrains. The other path drives the comb brush to perform linear reciprocating motion, cleaning surface dirt in real time while the brush plate rotates, preventing dirt accumulation from affecting cleaning efficiency. This linkage design requires no additional power source, improving the comprehensiveness and thoroughness of dirt cleaning, and achieving self-cleaning of cleaning components, reducing the frequency of manual maintenance, and significantly enhancing the continuous operation capability and practicality of the device.

[0019] 3. The robot inspection path cleaning device for gas-fired power plants described in this invention features a dust collection mechanism and a telescopic mechanism that operate in tandem to achieve efficient dust handling and flexible cleaning. The dust pump draws dust into the filter canister through a pipeline, and clean gas is discharged after filtration through the filter screen. A motor drives an anti-clogging brush to clean the filter screen, while a bevel gear drive drives a lead screw to clean the anti-clogging brush. Impurities fall into a collection box for easy cleaning and to prevent clogging. When the telescopic mechanism is held by hand, the angle of the suction pipe can be flexibly adjusted using steel balls, star-shaped sleeves, etc., to reach narrow areas. Sliding parts ensure unobstructed passage, and a spring pulls the device back to its original position after cleaning. The overall design improves dust cleaning efficiency and range, reduces manual maintenance, and enhances the practicality of the device. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 8 As shown in the embodiment of the present invention, a robot inspection path cleaning device for a gas-fired power plant includes a robot body 1. A base plate 10 is fixedly installed on the lower surface of the robot body 1. A moving mechanism 9 is provided at each of the four corners of the base plate 10 facing the ground for smooth movement. A first driving mechanism 2 and a second driving mechanism 4 are fixedly installed on the lower surface of the base plate 10. The first driving mechanism 2 is provided with a first cleaning mechanism 3 for cleaning hardened oil stains. The second driving mechanism 4 is provided with a second cleaning mechanism 5 for cleaning stains on the ground and a first brush cleaning mechanism 6 for processing the second cleaning mechanism 5. A dust collection mechanism 7 for collecting dust particles is fixedly installed on the upper surface of the base plate 10. A telescopic mechanism 8 is provided on one side of the dust collection mechanism 7 for cleaning dust accumulation in narrow areas.

[0032] Specifically, the base plate 10 under the robot body 1 moves smoothly via the four-corner moving mechanism 9. Hydraulic rods 91, damping springs 92, and casters 94 buffer vibrations and adapt to ground undulations, ensuring stable operation of the device. Under the base plate 10, the first drive mechanism 2 drives the first cleaning mechanism 3, which, through cranks 35, first sliders 33, and second sliders 34, drives the second cleaning shovel 37 to scrape away residual dirt on the first cleaning shovel 36. The first cleaning shovel 36 effectively breaks up and removes hardened oil stains. The second drive mechanism 4 not only allows the elastic brush plate 56 of the second cleaning mechanism 5 to flexibly clean ground stains, but also utilizes the first brush cleaning mechanism 6 to... The double-drive mechanism enables the first comb brush 64 to automatically clean the brush plate 56, avoiding dirt residue and reducing manual maintenance. The dust collection mechanism 7 on the base plate 10, through the cooperation of the third motor 75, anti-clogging brush 78, and dust pump 72, efficiently collects dust. The pull-out collection box 712 and the anti-clogging brush 78, in conjunction with the second comb brush 711, reduce the risk of clogging and improve maintenance convenience. Furthermore, the telescopic mechanism 8 on one side of the dust collection mechanism 7, using structures such as the retainer 84, star-shaped sleeve 86, and steel ball 85, allows the second suction pipe 81 to flexibly reach into narrow areas, solving the problem of dust accumulation dead corners. It is fully adaptable to the complex environment of gas-fired power plants, optimizes the cleaning of inspection paths, and assists in equipment inspection.

[0033] like Figures 2 to 4As shown, the first drive mechanism 2 includes a first mounting box 21 fixedly installed on the left side of the lower surface of the base plate 10. A first motor 22 is provided on one side of the first mounting box 21. Two sets of cross support frames 29 and a first support frame 28 are installed at equal intervals on the inner wall of the first mounting box 21. The output end of the first motor 22 is fixedly connected to a first drive shaft 26, and the first drive shaft 26 passes through the first mounting box 21. A first sprocket 23 is fixedly installed on both ends of the first drive shaft 26. A first chain 25 is meshed on the first sprocket 23. A second sprocket 24 is meshed on the end of the first chain 25 away from the first sprocket 23. A second drive shaft 27 is fixedly installed inside the second sprocket 24. The second drive shaft 27 is rotatably installed on the first support frame 28. A first gear 210 is fixedly installed on the end of the second drive shaft 27 away from the second sprocket 24. A second gear 211 is meshed on the outer side of the first gear 210. One side of the second gear 211 is fixedly connected to the first cleaning mechanism 3.

[0034] The first cleaning mechanism 3 includes a fixed shaft 31 fixedly installed inside the second gear 211. A crank 35 is fixedly installed at one end of the fixed shaft 31. A first slider 33 and a second slider 34 are fixedly installed at both ends of the crank 35 through bearings. The first slider 33 and the second slider 34 are slidably installed in the cross support frame 29. A second cleaning shovel 37 is fixedly installed on one side of the first slider 33 through bearings. A first cleaning shovel 36 is fixedly installed on one side of the second slider 34 through bearings. The first cleaning shovel 36 and the second cleaning shovel 37 are compatible with each other.

[0035] Specifically, during the cleaning operation of the robot inspection path in the gas-fired power plant, as the first cleaning shovel 36 in the first cleaning mechanism 3 continuously processes dirt, dirt will gradually accumulate on its surface. If it is not cleaned in time, it will affect the subsequent cleaning effect. When the dirt accumulates to a certain extent, the operator starts the first drive mechanism 2 to initiate the linkage cleaning process. The first motor 22 on one side of the first mounting box 21 starts to run first. The output end of the first motor 22 drives the first drive shaft 26 to rotate. The first drive shaft 26 passes through the first mounting box 21, and both ends of the first drive shaft 26... The fixed first sprocket 23 rotates synchronously with the shaft. Since the first sprocket 23 meshes with the first chain 25, power is transmitted through the first chain 25 to the second sprocket 24 at the end away from the first sprocket 23, causing the second sprocket 24 to rotate. The second drive shaft 27 fixed inside the second sprocket 24 rotates accordingly under the support of the first support frame 28. The first gear 210 fixed at the end of the second drive shaft 27 away from the second sprocket 24 begins to rotate due to the rotation of the second drive shaft 27. When the first gear 210 rotates, it drives the second gear 211 to rotate, which in turn interacts with the second gear 211. The first cleaning mechanism 3, fixedly connected, starts operating under the drive of the second gear 211. In the first cleaning mechanism 3, a fixed shaft 31, fixedly installed inside the second gear 211, rotates with the second gear 211, making circular motion. This, in turn, drives a crank 35 fixed at one end of the fixed shaft 31 to oscillate in a circular motion. The first slider 33 and the second slider 34, connected at both ends of the crank 35 via bearings, are pulled by the oscillation of the crank 35 and slide along a specific trajectory inside the cross support frame 29. Due to the limiting and guiding effect of the cross support frame 29, the first slider 33 and the second slider... The first slider 33 and the second slider 34 can reciprocate stably. During the reciprocating sliding of the first slider 33 and the second slider 34, the second cleaning shovel 37, which is mounted on one side of the first slider 33 via a bearing, will contact the cleaning surface of the first cleaning shovel 36, which is mounted on one side of the second slider 34 via a bearing. With the help of the relative movement of the two, the second cleaning shovel 37 can effectively scrape off the dirt accumulated on the first cleaning shovel 36, and complete the cleaning of the first cleaning shovel 36. This allows the first cleaning mechanism 3 to continue to carry out dirt cleaning work efficiently, ensuring the continuous and stable operation of the entire robot inspection path cleaning device.

[0036] like Figures 5 and 6As shown, the second drive mechanism 4 includes a fixed plate 47 equidistantly fixedly installed on the right side of the lower surface of the base plate 10. A second motor 41 is provided on one side of the fixed plate 47. A third drive shaft 45 is fixedly connected to the output end of the second motor 41. A third sprocket 42 is fixedly installed on the surface of the third drive shaft 45. A second chain 44 is meshed on the third sprocket 42. A fourth sprocket 43 is meshed at the end of the second chain 44 away from the first sprocket 23. A first reciprocating screw 46 is fixedly installed inside the fourth sprocket 43. The third drive shaft 45 is fixedly connected to the second cleaning mechanism 5. The first reciprocating screw 46 is in contact with the first brush cleaning mechanism 6 and is used to drive the first brush cleaning mechanism 6 to operate.

[0037] The second cleaning mechanism 5 includes multiple sets of fixed cylinders 51 fixed to the surface of the third drive shaft 45. Each set of fixed cylinders 51 has a first guide post 52 fixedly installed inside it. A brush plate 56 is fixedly installed at one end of each first guide post 52. Contact blocks 53 are slidably installed on the surface of each first guide post 52, and the contact blocks 53 are in contact with the brush plate 56. A first tension spring 54 is fixedly installed between the fixed cylinders 51 and the contact blocks 53. Second tension springs 55 are sleeved on the surface of each first guide post 52. One end of each spring 55 is fixedly mounted on a fixed cylinder 51. The end of the second tension spring 55 away from the multiple sets of fixed cylinders 51 is fixedly mounted on a contact block 53. The first brush cleaning mechanism 6 includes a collar 61 sleeved on the surface of the first reciprocating screw 46. A reciprocating slider 62 adapted to the first reciprocating screw 46 is fixedly mounted on the inner wall of the collar 61 by a bearing. An mounting block 63 is fixedly mounted on the surface of the collar 61. A first comb brush 64 adapted to the brush plate 56 is fixedly mounted on one side of the mounting block 63.

[0038] Specifically, when the second drive mechanism 4 is started, the operator starts the second motor 41 on one side of the fixed plate 47. The output end of the second motor 41 drives the third drive shaft 45 to rotate, and the third sprocket 42 on the surface of the third drive shaft 45 rotates accordingly. Through the meshing second chain 44, it drives the fourth sprocket 43 to rotate, thereby causing the first reciprocating screw 46 inside the fourth sprocket 43 to rotate synchronously, forming a dual-path power transmission. One path of power is transmitted from the third drive shaft 45 to the second cleaning mechanism 5. The third drive shaft 45 drives the multiple sets of fixed cylinders 51 fixed on the surface to rotate. The first guide post 52 inside the fixed cylinder 51 rotates accordingly, causing the brush plate 56 at one end to rotate, sweeping the dirt on the ground and the cleaning shovel. At this time, the contact surface of the first guide post 52... Block 53 contacts the brush plate 56. The first tension spring 54 between the fixed cylinder 51 and the contact block 53, together with the second tension spring 55 sleeved on the first guide post 52, pushes the contact block 53 through elastic extension and contraction to ensure that the bristles on the brush plate 56 are always close to the ground, thus ensuring the cleaning effect. Another power is transmitted from the first reciprocating screw 46 to the first brush cleaning mechanism 6. When the first reciprocating screw 46 rotates, the reciprocating slider 62 installed on the inner wall of the collar 61 through the bearing is adapted to the first reciprocating screw 46, converting the rotational motion into linear reciprocating motion, which drives the mounting block 63 and the first comb brush 64 on the surface of the collar 61 to move back and forth. Since the first comb brush 64 is adapted to the brush plate 56, it can clean the surface stains of the brush plate 56 in real time while the brush plate 56 is rotating and cleaning, thus achieving synchronous cleaning.

[0039] like Figures 7 to 8 As shown, the vacuuming mechanism 7 includes a filter canister 71 fixedly mounted on the upper surface of the base plate 10. A filter screen plate 74 is fixedly mounted on the inner wall of the filter canister 71. A third motor 75 is fixedly mounted on one end of the filter canister 71. The output end of the third motor 75 extends into the filter canister 71. An anti-clogging brush 78 adapted to the filter screen plate 74 is fixedly mounted on the output end of the third motor 75. A second mounting box 79 is fixedly mounted on one side of the anti-clogging brush 78. A second reciprocating screw 710 is rotatably mounted inside the second mounting box 79. A second comb brush 711 for cleaning impurities on the anti-clogging brush 78 is sleeved on the surface of the second reciprocating screw 710. A second bevel tooth 77 is fixedly installed at one end of the 10, and a first bevel tooth 76 is fixedly installed on the output end surface of the third motor 75. The first bevel tooth 76 meshes with the second bevel tooth 77. A vacuum pump 72 is fixedly installed on the outside of the filter canister 71. A first vacuum pipe 73 is fixedly installed inside the vacuum pump 72 and extends into the filter canister 71. An exhaust pipe 714 for discharging clean gas is fixedly installed at one end of the filter canister 71. A through groove is opened on the filter canister 71, and a collection box 712 is slidably installed in the through groove. A handle 713 is fixedly installed on one side of the collection box 712. One end of the first vacuum pipe 73 is fixedly connected to the telescopic mechanism 8.

[0040] The telescopic mechanism 8 includes a connecting cover 87 fixedly connected to one end of the first suction pipe 73. A retainer 84 is provided inside the connecting cover 87, and a star-shaped sleeve 86 is provided inside the retainer 84. A steel ball 85 is provided between the retainer 84 and the star-shaped sleeve 86. Both the retainer 84 and the star-shaped sleeve 86 are provided with limiting spaces for accommodating the steel ball 85. A connecting pipe 82 is slidably connected to the inner wall of the star-shaped sleeve 86. A first slip ring 83 and a second slip ring 88 are fixedly installed at both ends of the connecting pipe 82, respectively. The first slip ring 83 is slidably connected inside the first suction pipe 73. A second suction pipe 81 is fixedly installed on the surface of the second slip ring 88. A return spring 89 is sleeved on the surface of the connecting pipe 82. One end of the return spring 89 is fixedly connected to the second slip ring 88, and the end of the return spring 89 away from the second slip ring 88 is fixedly connected to the bottom surface of the connecting cover 87.

[0041] Specifically, when the vacuuming mechanism 7 and the telescopic mechanism 8 operate in conjunction, they achieve efficient dust collection, filtration, and cleaning of narrow areas. During vacuuming, the vacuum pump 72 on the outside of the filter canister 71 is activated. After the vacuum pump 72 is activated, it generates suction through the first vacuum pipe 73. Dust enters the connecting pipe 82 through the second vacuum pipe 81, and then enters the first vacuum pipe 73 through the connecting pipe 82, and is finally sucked into the filter canister 71. The filter screen 74 on the inner wall of the filter canister 71 filters the dust, and the filtered clean air is discharged from the exhaust pipe 714. To prevent the filter screen 74 from clogging... When the filter screen is closed, the third motor 75 starts, and the output end of the third motor 75 drives the anti-clogging brush 78 to rotate, scraping off the impurities on the filter screen 74. At the same time, the output end of the third motor 75 drives the first bevel tooth 76 to rotate, and the first bevel tooth 76 meshes with and drives the second bevel tooth 77 to rotate, which in turn drives the second reciprocating screw 710 in the second mounting box 79 to rotate, causing the second comb brush 711 to move back and forth along the screw, cleaning the impurities on the anti-clogging brush 78. The impurities finally fall into the collection box 712 of the filter barrel 71, and the collection box 712 can be pulled out for cleaning by the handle 713.

[0042] When the operator holds the telescopic mechanism 8 for operation, the various components work together to achieve flexible adjustment and reset. The connecting cover 87 is fixed to one end of the first suction pipe 73. A steel ball 85 is installed between the retainer 84 and the star-shaped sleeve 86 inside the connecting cover 87. The steel ball 85 is embedded in the limiting space of the two to form a rotatable support structure. The connecting pipe 82 is slidably connected to the inner wall of the star-shaped sleeve 86. The two ends of the connecting pipe 82 are respectively connected by a first slip ring 83 and a second slip ring 88. The connecting pipe 82 connects the first suction pipe 73 and the second suction pipe 81, which not only ensures that the suction passage is unobstructed, but also provides room for angle adjustment. When it is necessary to clean a narrow area, the operator rotates the second suction pipe 81, and the star-shaped sleeve 86 moves with the second suction pipe 81. 1. With synchronous rotation, the steel ball 85 rolls within the limiting space of the retainer 84 and the star-shaped sleeve 86, reducing rotational resistance and allowing the second suction pipe 81 to flexibly adjust its turning angle, effectively targeting dust-accumulated dead corners. At the same time, the first slip ring 83 slides within the first suction pipe 73, and the second slip ring 88 moves with the connecting pipe 82, ensuring that the suction passage remains uninterrupted during adjustment. After cleaning, the reset spring 89 on the surface of the connecting pipe 82 takes effect. One end of the reset spring 89 is fixed to the second slip ring 88, and the other end of the reset spring 89 is connected to the bottom surface of the connecting cover 87. Through elastic contraction, it pulls the second slip ring 88, the connecting pipe 82, and the second suction pipe 81 to reset, allowing the telescopic mechanism 8 to return to its initial state, ready for the next operation.

[0043] like Figure 1 As shown, the moving mechanism 9 includes hydraulic rods 91 that are fixedly installed on the base plate 10 facing the four corners of the ground. The bottom end of the hydraulic rod 91 is fixedly installed with a base 93. A caster wheel 94 is fixedly installed on the base 93 through a bearing. A damping spring 92 is sleeved on the surface of the hydraulic rod 91, and one end of the damping spring 92 is fixedly installed on the base 93.

[0044] Specifically, the four hydraulic rods 91 at the corners can flexibly adjust the height of the base plate 10, easily adapting to different ground protrusions or depressions within the gas-fired power plant, ensuring the device remains level and stable in complex terrain. The casters 94 mounted on the base 93 via bearings give the device flexible steering capabilities, facilitating adjustments to the direction of travel in densely populated areas and increasing the coverage of the inspection path. The damping springs 92 fitted on the surface of the hydraulic rods 91, with one end fixed to the base 93, effectively buffer vibrations caused by ground bumps during movement, reducing impact on the mechanisms on the base plate 10, protecting precision components, maintaining the stability of the cleaning operation, reducing noise during device operation, and extending the overall service life.

[0045] like Figures 5 to 7 As shown, the surfaces of the second reciprocating lead screw 710 and the first reciprocating lead screw 46 are both provided with left-right intersecting helical grooves to guide automatic reversal.

[0046] Specifically, the left-right intersecting spiral grooves on the surfaces of the second reciprocating lead screw 710 and the first reciprocating lead screw 46 can stably convert the rotational motion into the linear reciprocating motion of the reciprocating slider 62 and the second comb brush 711. This ensures that the cleaning action of the first comb brush 64 on the brush plate 56 and the second comb brush 711 on the anti-clogging brush 78 is continuous and comprehensive. The left-right intersecting spiral grooves can guide the components to automatically change direction, achieving smooth switching of reciprocating motion without additional control devices. This simplifies the transmission structure, avoids jamming during direction changes, ensures that the cleaning components always operate efficiently, reduces maintenance needs, and improves the operational stability and automation of the entire cleaning device.
