Description

Technical Field

[0001] The present invention relates to the technical field of robot manufacturing, and particularly relates to an intelligent inspection robot for a power station. Background Art

[0002] A power station refers to a site that provides power energy. The power station generates corresponding energy by converting different energies in nature into mechanical energy. Power machinery can be divided into three categories: wind machinery, water conservancy machinery, and thermal machinery. Wind machinery includes sailboats, wind turbines, etc.; water conservancy machinery includes waterwheels, water turbines, etc.; thermal machinery includes steam engines, steam turbines, internal combustion engines, etc. As the society's demand for energy continues to increase, large-scale power stations have emerged. In order to ensure the normal operation of the power station, it is necessary to regularly inspect and maintain the power station. The traditional inspection method is mainly manual, which is dangerous and inefficient. Therefore, inspection robots have emerged. The inspection robot can realize the automatic monitoring of fires, harmful gases, etc. in the power station, changing the previous manual monitoring method, reducing the labor intensity, lowering the work danger, improving the work efficiency and reducing the cost.

[0003] During the inspection process of the existing inspection robots, they cannot handle the generated dust, causing the dust to accumulate and affecting the normal operation of the power station equipment. At the same time, when the inspection robot is patrolling, there may be obstacles on the planned path. When the inspection robot moves forward, collisions may occur, causing damage to the inspection robot. In view of this, we propose an intelligent inspection robot for a power station.

Detailed implementation mode

[0028] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0029] Embodiment 1

[0030] As Figure 1-5 shown, this embodiment discloses an intelligent inspection robot for a power station. A bottom plate 2 is arranged at the lower part of the outer shell 1, and a support platform 3 is arranged in the middle of the upper end of the outer shell 1. The support platform 3 is a prior art for adjusting the direction and angle of the camera 4. A camera 4 is arranged on the upper part of the support platform 3. The camera 4 is a prior art for monitoring the equipment of the power station. A motor 5 is arranged in the middle of the upper end of the bottom plate 2. The motor 5 is a prior art for driving the device to operate. A transmission device 6 is arranged at the output end of the motor 5. The transmission device 6 is to transmit the force output by the motor 5 to other devices and at the same time make the inspection robot move. A cleaning device 7 is arranged on one side of the upper end of the bottom plate 2 away from the motor 5. The cleaning device 7 is to clean the dust on the traveling route of the inspection robot.

[0031] In order to transmit the power output by the motor 5 to other devices, such as Figure 3 , the transmission device 6 includes a screw rod 61 fixedly connected to the output end of the motor 5. A first spur gear 62 is meshed and connected to the lower part of the screw rod 61. A first transmission roller 63 rotatably connected to the inner wall of the bottom plate 2 is arranged on the inner wall of the first spur gear 62. A first bevel gear 64 is arranged on the outer surface of the first transmission roller 63 on the side away from the motor 5. A second bevel gear 65 is meshed and connected to the side of the first bevel gear 64 close to the motor 5.

[0032] Further, a second transmission roller 66 is arranged at one end of the second bevel gear 65 close to the cleaning device 7. The second transmission roller 66 is arranged to prevent the device connected to the first driven roller 69 from being unable to rotate due to excessive force, resulting in the device moving too slowly and at the same time causing wear to the wheels 60. A third bevel gear 67 is arranged on the outer surface of the second transmission roller 66 on the side close to the cleaning device 7. A fourth bevel gear 68 is meshed and connected to the side of the third bevel gear 67 close to the dust collection device 8.

[0033] Further, a first driven roller 69 rotatably connected to the inner wall of the bottom plate 2 is arranged on the inner wall of the fourth bevel gear 68. Wheels 60 are arranged on both sides of the outer surfaces of the first transmission roller 63 and the first driven roller 69. The wheels 60 rotate simultaneously under the drive of the first transmission roller 63 and the first driven roller 69.

[0034] In order to continuously sweep the dust on the ground to the middle of the traveling route of the inspection robot by the broom 772, such as Figure 4As shown, the cleaning device 7 includes a fifth bevel gear 71 fixedly connected to the middle of the outer surface of the first driven roller 69. On the side of the fifth bevel gear 71 away from the motor 5, there is a meshing connection with a sixth bevel gear 72. The fifth bevel gear 71 and the sixth bevel gear 72 are used to connect the transmission device 6 to make the cleaning device 7 move. At the end of the sixth bevel gear 72 away from the motor 5, there is a second driven roller 721. The outer surface of the second driven roller 721 is rotatably connected to a fixing plate 73. On both sides of the middle of the outer surface of the fixing plate 73 near the two wheels 60, there are first connecting rods 731.

[0035] Furthermore, at the lower part of the outer surface of the fixing plate 73, there is a transmission connecting rod 70 fixedly connected to the outer surface of the second driven roller 721. The first connecting rod 731 is used to support the transmission connecting rod 70 and at the same time limit the transmission connecting rod 70 so that the transmission connecting rod 70 can only move left and right. At the end of the second spur gear 74 away from the motor 5, there is a first transmission gear ring 741. The upper part of the second spur gear 74 is meshingly connected to a third spur gear 75. The upper part of the third spur gear 75 is meshingly connected to a fourth spur gear 76. Both the third spur gear 75 and the fourth spur gear 76 are rotatably connected to the inner wall of the fixing plate 73.

[0036] Furthermore, at the end of the fourth spur gear 76 away from the motor 5, there is a second transmission gear ring 761. Driven by the second spur gear 74 and the fourth spur gear 76, the first transmission gear ring 741 and the second transmission gear ring 761 rotate in the same direction. At the lower part of the second transmission gear ring 761, there is a transmission connecting rod 70. The transmission connecting rod 70 is used to connect the first transmission gear ring 741 and the second transmission gear ring 761 and continuously reciprocate under the drive of the second transmission gear ring 761 and the first transmission gear ring 741, and always one of the first transmission gear ring 741 and the second transmission gear ring 761 meshes with the transmission connecting rod 70.

[0037] Furthermore, on both sides of the transmission connecting rod 70, there are lifting connecting rods 77. The lifting connecting rods 77 are used to connect the brooms 772 and reciprocate with the transmission connecting rod 70. At the lower part of the side of both lifting connecting rods 77 near the motor 5, there are lifting devices 78. The lifting devices 78 are used to lift the lifting connecting rods 77 when the lifting connecting rods 77 move outwards, so as to prevent the brooms 772 from pushing the dust to the outside of the patrol robot's traveling route when moving outwards, resulting in dust accumulation.

[0038] In order to transmit the force to the lifting connecting rods 77 and at the same time generate continuous left and right movement, as Figure 4 shown, the transmission connecting rod 70 includes a transmission rod 701 slidably connected to the inner wall of the first connecting rod 731. At the middle of the upper and lower ends of the transmission rod 701, there are teeth 702. On both sides of the transmission rod 701 near the wheel 60, there are second connecting rods 703.

[0039] Specifically, when the second drive gear ring 761 and the first drive gear ring 741 rotate, the second drive gear ring 761 meshes with and connects to the drive connecting rod 70 and moves to one side. When the second drive gear ring 761 disengages from the drive connecting rod 70, the first drive gear ring 741 meshes with the drive connecting rod 70 at this time, causing the drive connecting rod 70 to move to the other side. When the first drive gear ring 741 disengages from the drive connecting rod 70, the second drive gear ring 761 meshes with the drive connecting rod 70 again, thereby causing the drive connecting rod 70 to continuously reciprocate.

[0040] To connect the broom 772 while preventing dust from entering the interior of the device, as Figure 5 shown, the lifting connecting rod 77 includes a lifting rod 771 that is slidably connected to the inner wall of the second connecting rod 703. A broom 772 is provided at the lower end of the lifting rod 771. The broom 772 is used to sweep the dust on the travel route of the inspection robot to prevent the dust from affecting the normal operation of the power station equipment.

[0041] Furthermore, dust-proof curtains 773 are slidably connected to both side surfaces of the lifting rod 771 near the two wheels 60. The dust-proof curtains 773 are provided to prevent dust from entering the interior of the device through the holes in the bottom plate 2 when the lifting rod 771 moves along with the drive connecting rod 70, which may affect the normal operation of the device. At the same time, when the lifting rod 771 moves, one side of the dust-proof curtain 773 contracts and the other side expands, which can effectively prevent dust from entering the interior of the device. The dust-proof curtains 773 are slidably connected to the inner wall of the bottom plate 2. A lifting block 774 is provided on one side surface of the lifting rod 771 near the motor 5. The lifting block 774 is used to cooperate with the lifting device 78 to lift the lifting rod 771.

[0042] To prevent the broom 772 from pushing the dust outside the travel route of the inspection robot and causing dust accumulation when one side of the lifting connecting rod 77 moves outward, as Figure 5 shown, the lifting device 78 includes a positioning plate 781 fixedly connected to the upper end of the bottom plate 2. The positioning plate 781 is used to fix the limiting block 782. A limiting block 782 is provided on the upper part of the side surface of the positioning plate 781 away from the motor 5.

[0043] Furthermore, a lifting inclined plate 783 is rotatably connected to the side of the two limiting blocks 782 that are close to each other. The lifting inclined plate 783 can lift the lifting rod 771 through the lifting block 774 when the lifting connecting rod 77 moves outward, thereby causing the broom 772 to disengage from the ground. The distance between the lower end of the limiting block 782 and the upper end of the bottom plate 2 is adapted to the height of the lifting block 774.

[0044] Specifically, when the lifting rod 771 moves outward, under the action of the lifting inclined plate 783, the lifting block 774 lifts the lifting rod 771, so that the broom 772 is separated from the ground. When the lifting rod 771 moves inward, the lifting block 774 moves inward through the channel under the limiting block 782. When it touches the lifting inclined plate 783, it lifts the lifting inclined plate 783. When the lifting block 774 is separated from the lifting inclined plate 783, the lifting inclined plate 783 returns to its original position under the action of gravity, so that when the lifting block 774 moves outward, the lifting connecting rod 77 is lifted by the lifting block 774.

[0045] In summary, the specific implementation method is as follows: Start the motor 5, and the inspection robot moves. At this time, under the action of the transmission device 6, the force output by the motor 5 is transmitted to the cleaning device 7. The second straight gear 74, the third straight gear 75, and the fourth straight gear 76 rotate simultaneously, and the first transmission gear ring 741 and the second transmission gear ring 761 provided on the second straight gear 74 and the fourth straight gear 76 also rotate simultaneously. The first transmission gear ring 741 and the second transmission gear ring 761 drive the transmission connecting rod 70 to perform reciprocating motion, and the lifting connecting rods 77 on both sides of the transmission connecting rod 70 also perform reciprocating motion simultaneously. At the same time, when the lifting connecting rod 77 performs reciprocating motion, the lifting block 774 on the lifting connecting rod 77 lifts the lifting connecting rod 77 under the action of the lifting device 78, so that the lifting connecting rod 77 moving outward on one side is lifted, and at this time the broom 772 is separated from the ground contact. The lifting connecting rod 77 moving inward on the other side will not be lifted, and the dust is swept to the middle of the traveling route of the inspection robot.

[0046] In the above implementation method, when the second transmission gear ring 761 and the first transmission gear ring 741 rotate, the second transmission gear ring 761 meshes with and connects the transmission connecting rod 70 to move to one side. When the second transmission gear ring 761 is separated from the transmission connecting rod 70, the first transmission gear ring 741 meshes with the transmission connecting rod 70 at this time, so that the transmission connecting rod 70 moves to the other side. When the first transmission gear ring 741 is separated from the transmission connecting rod 70, the second transmission gear ring 761 meshes with the transmission connecting rod 70 again, thereby enabling the transmission connecting rod 70 to continuously perform reciprocating motion.

[0047] In addition, when the lifting rod 771 moves outward, under the action of the lifting inclined plate 783, the lifting block 774 lifts the lifting rod 771, so that the broom 772 is separated from the ground. When the lifting rod 771 moves inward, the lifting block 774 moves inward through the channel under the limiting block 782. When it touches the lifting inclined plate 783, it lifts the lifting inclined plate 783. When the lifting block 774 is separated from the lifting inclined plate 783, the lifting inclined plate 783 returns to its original position under the action of gravity, so that when the lifting block 774 moves outward, the lifting connecting rod 77 is lifted by the lifting block 774.

[0048] Embodiment 2

[0049] Based on the first embodiment, this embodiment further improves the driven roller 69 of the transmission device 6 in terms of transmission, as Figure 6-7 shown. A dust suction device 8 is provided on the side of the inner cavity of the housing 1 away from the motor 5. The dust suction device 8 is used to suck the dust swept by the cleaning device 7 onto the traveling route of the inspection robot into the device interior.

[0050] In order to suck the dust into the device interior and then have it cleaned by the staff, as Figure 6 shown, the dust suction device 8 includes a dust suction housing 81. The lower inner wall of the dust suction housing 81 is rotatably connected to a driven roller three 82. A bevel gear seven 83 is provided at the lower end of the driven roller three 82. The lower part of the bevel gear seven 83 is meshed with a bevel gear eight 84. The inner wall of the bevel gear eight 84 is fixedly connected to the outer surface of the driven roller 69 on the side away from the bevel gear four 68. A fan blade 86 fixedly connected to the upper part of the outer surface of the driven roller three 82 is provided in the lower part of the inner cavity of the dust suction housing 81. The fan blade 86 rotates as the bevel gear seven 83 and the driven roller three 82 move with the inspection robot, thereby generating suction.

[0051] Furthermore, an exhaust passage 85 is provided on the side of the dust suction housing 81 away from the cleaning device 7, and the exhaust passage 85 extends to the outer surface of the housing 1. The exhaust passage 85 is used to discharge the filtered air to the outside of the device. A filtering device 87 is provided in the middle of the dust suction housing 81. The filtering device 87 is used to collect dust for the staff to clean the dust, and at the same time filter the air to avoid polluting the environment with dusty air.

[0052] Furthermore, an air suction pipe 88 is provided on the upper part of the outer surface of the dust suction housing 81 close to the cleaning device 7. The air suction pipe 88 is used to connect the suction nozzle 89 and the dust suction housing 81, so that the dust is sucked from the suction nozzle 89 into the dust suction housing 81. The lower part of the outer surface of the air suction pipe 88 is fixedly connected to the inner wall of the bottom plate 2, and a suction nozzle 89 is provided at the lower end of the air suction pipe 88.

[0053] In order to facilitate the staff to clean the dust and at the same time facilitate the replacement of the filter net 872, as Figure 7 shown, the filtering device 87 includes a fixing ring 871 slidably connected to the inner wall of the dust suction housing 81. A connecting groove 811 is provided in the middle of the inner cavity surface of the dust suction housing 81. The shape and size of the connecting groove 811 are adapted to the surface of the fixing ring 871 on the side close to the cleaning device 7. A filter net 872 is provided at the lower part of the fixing ring 871. The filter net 872 is used to filter the air. A connecting block 873 slidably connected to the inner wall of the housing 1 is provided on the side of the fixing ring 871 away from the cleaning device 7. The connecting block 873 can be pulled to pull the entire filtering device 87 away from the dust suction device 8.

[0054] In summary, the specific implementation method is as follows: When the inspection robot moves, the driven roller three 82 also starts to rotate simultaneously to generate suction force. Under the action of the suction force of the fan blade 86, the suction nozzle 89 located at the bottom of the inspection robot sucks the dust swept to the middle of the traveling route of the inspection robot into the device. After being filtered by the filter screen 872, the air is discharged from the exhaust passage 85, while the dust remains inside the filtering device 87. After the inspection robot finishes the inspection, the filtering device 87 can be removed from the outer shell 1 by personnel to clean the dust on the filtering device 87 and replace the filter screen 872.

[0055] In the above embodiment, the transmission of the bevel gear eight 84 follows the transmission of the driven roller one 69, and the driven roller three 82 on the bevel gear seven 83 also rotates accordingly, thereby driving the fan blade 86 to rotate, thus generating suction force.

[0056] Embodiment III

[0057] In this embodiment, on the basis of Embodiment I, the outer shell 1 is further improved, as Figure 8 shown, buffer devices 9 are arranged on both sides of the outer surface of the outer shell 1 away from the camera 4. The buffer devices 9 are used to prevent the inspection robot from hitting an object during the inspection, so as to avoid damage to the inspection robot due to excessive impact force.

[0058] In order to avoid damage to the inspection robot caused by impact, as Figure 8 shown, the buffer device 9 includes a collision-proof rod 91 slidably connected to the inner wall of the outer shell 1. At one end of the two collision-proof rods 91 close to each other, two springs 93 are arranged. One end of the spring 93 close to the motor 5 is fixedly connected to a buffer shell 92, and one end of the two buffer shells 92 away from each other is fixedly connected to the inner cavity surface of the outer shell 1.

[0059] In summary, the specific implementation method is as follows: When the inspection robot hits an object or other things hit the inspection robot, the collision-proof rod 91 transmits the force to the spring 93. The spring 93 buffers the force through its own deformation and transmits it to the buffer shell 92, thereby avoiding the impact force directly acting on the inspection robot and causing damage to the inspection robot.
