Description

Technical Field

[0001] The invention belongs to the technical field of inspection robots, in particular to an electric power inspection robot. Background Art

[0002] With the development of intelligent inspection robot technology, in order to save manpower, a large number of small power stations and other power facilities often adopt an unmanned mode. For the monitoring of the normal working status of power equipment, intelligent inspection robots are usually used to conduct daily inspections and inspect the normal operation of power equipment. In the event of a fault or other accident, they can promptly provide alarm feedback to notify maintenance personnel to rush to carry out repairs in time, thereby reducing the probability of electrical accidents and ensuring the normal operation of the power network.

[0003] Because small, unmanned power stations typically have a small footprint and narrow internal passageways, inspection robots are required to penetrate the gaps between motors and equipment during in-depth inspections of power equipment. Consequently, inspection robots are limited in size and are generally smaller. While this allows for greater mobility, it also limits the working range of the inspection robot's monitoring terminal, making it difficult to fully inspect all parts of the power equipment.

If a single telescopic device fails, the position adjustment cannot be carried out, and the risk resistance is poor.

Implementation Method

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Example

[0032] With the development of intelligent inspection robot technology, in order to save manpower, a large number of small power stations and other power facilities often adopt an unmanned mode. For the monitoring of the normal working status of power equipment, intelligent inspection robots are usually used to conduct daily inspections and inspect the normal operation of power equipment. In the event of a fault or other accident, they can promptly provide alarm feedback to notify maintenance personnel to rush to carry out repairs in time, thereby reducing the probability of electrical accidents and ensuring the normal operation of the power network.

[0033] Because small, unmanned power stations typically have a small footprint and narrow internal passageways, inspection robots are required to penetrate the gaps between motors and equipment during in-depth inspections of power equipment. Consequently, inspection robots are limited in size and are generally smaller. While this allows for greater mobility, it also limits the working range of the inspection robot's monitoring terminal, making it difficult to fully inspect all parts of the power equipment.

[0034] Therefore, in order to expand the operating range, the existing technology sets a telescopic device to drive the monitoring end to adjust its position in the vertical direction to expand the monitoring range; however, this position adjustment method is inflexible. If a single telescopic device fails, the position adjustment will be impossible, and the risk resistance is poor. Moreover, during the telescopic process, the monitoring end is not stable on the telescopic end, which affects the smooth progress of the monitoring operation.

[0035] Therefore, in order to effectively solve the above problems, the present application proposes an electric power inspection robot, as shown in the accompanying drawings of the specification. Figures 1-6As shown, the vehicle comprises a vehicle body 1, an inspection device 2, a detection radar, and an intelligent control center. The vehicle body 1 is provided with moving wheels at the bottom, which are driven by a motor and move according to a route stored in the intelligent control center or are remotely controlled by an operator. The inspection device 2 includes an inspection camera 21 and a safety sensor 22, which are used to collect operating information of power equipment inside unmanned power stations during inspections. The detection radar is used to detect obstacles around the vehicle body 1 during its movement and provide feedback to the intelligent control center to adjust the inspection route.

[0036] The vehicle body 1 further includes a position adjustment module 3 for adjusting the height of the inspection device 2, thereby expanding the inspection detection range. The position adjustment module 3 includes a mounting plate 31, which is disposed in a mounting groove 11 disposed on the upper surface of the vehicle body 1. The vertical cross-sections of the mounting plate 31 and the mounting groove 11 are both square, and the edge ends of the mounting plate 31 are slidably connected to the side walls of the mounting groove 11.

[0037] Multiple mounting plates 31 are arranged vertically and overlap each other. Telescopic devices 32 are installed in the gaps between the mounting plates 31. Each telescopic device 32 is controlled by an intelligent control center, and its maximum extension distance is greater than the internal height of the mounting slot 11. The telescopic devices 32 here can be electric telescopic rod devices, which are distributed at the bottom of the mounting slot 11 and on the upper surface of each mounting plate 31 except the topmost mounting plate 31. The overlapping mounting plates 31 form a multi-layer structure, and the telescopic devices 32 located in the gaps between the same mounting plates 31 are grouped together. Each group of telescopic devices 32 contains four telescopic devices 32, each located near the four corners of the square surface of the mounting plate 31. The inspection camera 21 and the safety sensor 22 are respectively installed on the upper surfaces of different mounting plates 31.

[0038] An inductive sensor 12 is provided at the bottom of the vehicle body 1. The inductive sensor 12 corresponds to a positioning plate 4 provided on the inspection route. A sensing chip and a transmitter are provided inside the positioning plate 4. When the inductive sensor 12 is close to the sensing chip, the position information is transmitted to the receiver at the bottom of the vehicle body 1 through the transmitter. The receiver is triggered and fed back to the intelligent control center to determine its own position, so as to facilitate the correction of the inspection route.

[0039] Specific workflow: The power inspection robot located in the power station can be activated according to a pre-set time and route to inspect power equipment throughout the power station. Before the inspection, the inspection route needs to be planned based on the distribution of power equipment within the power station and input into the automatic control center to facilitate the control of the inspection robot to inspect the power equipment along the route.

[0040] During routine inspections, the vehicle body 1, under the control of the intelligent control center, drives the moving wheels through the motor to move the vehicle body 1 along the inspection route. When it moves to the inspection point next to the power equipment, the vehicle body 1 stops moving. If the movement route of the vehicle body 1 is correct, the vehicle body 1 moves to the upper side of the positioning plate 4 at the inspection point. The induction sensor 12 at the bottom of the vehicle body 1 and the induction chip inside the positioning plate 4 are close to each other and triggered, and feedback is sent to the intelligent control center, indicating that the inspection route is correct.

[0041] If the robot fails to correctly move to the inspection point, the induction sensor 12 is not triggered, indicating that the inspection route is incorrect. In this case, the information is fed back to the intelligent control center, which uses the onboard inspection radar to detect the surroundings and automatically correct the position based on surrounding reference objects. Alternatively, the information is fed back to the remote monitoring personnel, who use the images captured by the inspection camera 21 to understand the robot's current position and then perform remote manual corrections to ensure that the inspection robot's movement route is correct and that it can successfully complete the normal inspection of the power equipment in the power station.

[0042] When the inspection point of a relatively large power equipment is located, in order to fully inspect the power equipment, the No. 1 telescopic device 32 on the mounting plate 31 is activated to lift the inspection device 2 and continue the inspection. Specifically, the telescopic length of the No. 1 telescopic device 32 is set as needed through the intelligent control center, thereby adjusting the vertical height of the inspection camera 21 and various safety sensors 22 on the mounting plate 31 to facilitate the inspection of different parts of the power equipment. By setting up multiple layers of the mounting plate 31, redundancy is increased. In this way, even if the No. 1 telescopic device 32 on one layer fails, the No. 1 telescopic devices 32 on other layers can still work to ensure the position adjustment of the inspection device 2.

[0043] In addition, through the multi-layer setting, multi-stage start-up of the vertical telescopic device No. 1 32 is achieved, the telescopic range is larger, and the vertical position adjustment is more flexible; and the sliding connection between the square mounting plate 31 and the mounting groove 11 limits the horizontal shaking of the entire position adjustment module 3, thereby ensuring that the inspection device 2 obtains a stable working platform during the inspection operation, so that the inspection operation of the power equipment can be carried out smoothly. Example

[0044] On the basis of the first embodiment, an inspection platform 33 is provided on the upper surface of the mounting plate 31 located at the uppermost side. The inspection platform 33 is rotatably connected to the mounting plate 31. A rotating motor is provided at the rotatable connection portion between the inspection platform 33 and the mounting plate 31. Under the control of the intelligent control center, the inspection camera 21 can be driven to rotate relative to the mounting plate 31. The inspection camera 21 is provided on the inspection platform 33.

[0045] Except for the top mounting plate 31, each mounting plate 31 has a slide groove 34 on its upper surface, and a slider 341 is provided on the slide groove 34. The slide groove 34 and the slider 341 can adopt the existing electric slider and electric slide rail matching technology. Under the control of the intelligent control center, the slider 341 automatically slides along the slide groove 34. The safety sensor 22 is installed on the slider 341; a detection rod 35 is provided on the slider 341. The detection rod 35 is a horizontal T-shaped structure, and the horizontal portion of the detection rod 35 extends horizontally, and the top of the vertical portion contacts the lower surface of the adjacent mounting plate 31 on the upper side; the safety sensor 22 is installed on the detection rod 35;

[0046] Specific workflow: Based on the specific workflow in Example 1, the inspection camera 21 located on the uppermost mounting plate 31 is configured to achieve the highest telescopic height. The inspection platform 33 is used to drive the inspection camera 21 to rotate, thereby allowing the inspection camera 21 to obtain a wider shooting field of view, thereby fully capturing the working conditions of various power equipment inside the power station. The captured video data is then transmitted to a remote monitoring center and stored, assisting maintenance personnel in fully understanding the working conditions inside the power station, identifying problems in a timely manner, and reducing the occurrence of accidents.

[0047] Safety sensors 22 for different environments can include various types, such as temperature and humidity sensors, harmful gas sensors, voltage and current sensors, etc. In the prior art, these safety sensors 22 are often integrated together to detect the interior of the power station. This detection method is not flexible enough, and different working environments can easily cause some safety sensors 22 to be damaged. Therefore, during the installation process, different types of safety sensors 22 can be installed on different mounting plates 31 for targeted detection.

[0048] For example, for safety sensors 22 with high frequency of use and strong anti-interference ability, they can be installed on the mounting plate 31 near the top, which is convenient for telescopic movement to the outside for operation; for sensors with low frequency of use, high precision and easy to damage, the mounting groove 11 is mounted on the mounting plate 31 near the bottom; except for a few scenarios where it needs to be raised to the limit, the mounting plate 31 at the bottom will not rise to the outside, so that it is located deep inside the mounting groove 11, and dust and moisture from the outside need to pass through the barrier of multiple layers of mounting plates 31 before affecting the mounting plate 31 in the deep part. Therefore, the safety sensor 22 on the mounting plate 31 in the deep part is safely protected and will only be telescopically moved away from the mounting groove 11 to start detection operation when needed. This can effectively resist adverse external influences, reduce the probability of damage, and increase the normal service life of some more precise sensors.

[0049] Furthermore, when the safety sensor 22 needs to work, the vehicle body 1 moves to the corresponding position, and the No. 1 telescopic device 32 connected to the mounting plate 31 where the safety sensor 22 is located is activated to separate the safety sensor 22 from the mounting groove 11 and contact the outside world; then the control slider 341 moves, driving the safety sensor 22 on the end of the detection rod 35 to leave the gap between the mounting plates 31 and approach the power equipment that needs to be detected. The horizontal portion of the detection rod 35 extending laterally can even drive the safety sensor 22 carried thereon to extend into the gap of the power equipment, deeply detecting the working condition of the power equipment, as well as the temperature and humidity of each part, and feeding back the data to the intelligent control center for recording and summary, making the use of the safety sensor 22 more flexible and efficient, and improving the accuracy of detection of the power equipment;

[0050] Furthermore, the detection rod 35 is a horizontal T-shaped structure, with a safety sensor 22 installed on the end of the horizontal part, and the top of the vertical part is higher than the horizontal part and is equipped with a pressure sensor; when the length of the No. 1 telescopic device 32 between the mounting plates 31 is too short, the gap between the mounting plates 31 is too small, and the top of the detection rod 35 located in the gap presses against the adjacent upper mounting plate 31 and triggers the pressure sensor, which is fed back to the intelligent control center to stop further shortening, thereby ensuring the normal operation of the detection rod 35 in the gap and the safety sensor 22 carried thereon. Example

[0051] On the basis of the second embodiment, a mounting hole 36 is provided on the side wall of the mounting plate 31, a second telescopic device 361 is provided on the mounting hole 36, and a fixing member 362 is provided on the telescopic end of the second telescopic device 361 to achieve the limiting fixation of the mounting plate 31;

[0052] Specific workflow: Based on the specific workflow in Example 2, it is necessary to lift the mounting plate 31 where the inspection camera 21 is located to a higher position. This will cause multiple mounting plates 31 to detach from the mounting slots 11, and the center of gravity of the vehicle body 1 as a whole will also move upward, resulting in a weaker stability of the vehicle body 1. To ensure the stability of the vehicle body 1 as a working platform during the inspection process, when it is necessary to lift the vehicle body 1 to a higher height, after the vehicle body 1 is close to the power equipment, the number of mounting plates 31 to be activated is selected according to the telescopic height, and they are activated in sequence.

[0053] Among the mounting plates 31 that need to be activated, after the lowest mounting plate 31 is lifted to its maximum height, the second telescopic device 361 inside the mounting hole 36 on the mounting plate 31 is activated, pushing the fixing member 362 out of the mounting hole 36 and into contact with the surface of the power equipment facing it. The fixing member 362 and the contacted surface of the power equipment are attracted and fixed to each other, thereby fixing the lowest mounting plate 31 in place. The adjacent upper mounting plate 31 is then lifted upward, and the above operation is repeated until it reaches the predetermined height, so that the inspection camera 21 and the safety sensors 22 on each mounting plate 31 can normally inspect the power equipment.

[0054] During this lifting process, the mounting plates 31 that are successively moved upward are fixed and limited by the fixing members 362, and rely on the contact adsorption points between the fixing plates and the power equipment as support, thereby improving the stability of the vehicle body 1 during the lifting process. Moreover, after the lifting is completed, during the inspection, the fixed position of the mounting plates 31 at each level ensures the stability of the vehicle body 1, thereby ensuring the stability of the inspection camera 21 and the safety sensor 22 during the inspection, so that the inspection process proceeds smoothly and the accuracy of the inspection results is guaranteed.

[0055] Furthermore, there are multiple options for the fixing part 362 here. An electromagnet can be used to start the process by powering on to adsorb the iron surface of the electrical equipment to ensure the stability of the mounting plate 31. A fixed suction cup can also be used to adsorb the electrical equipment or smooth surfaces such as walls to ensure the stability of the mounting plate 31. Any implementation scheme that can achieve adsorption limitation and fix the mounting plate 31 can be applied to this application. Example

[0056] On the basis of the third embodiment, cleaning holes 311 are provided in the interior of the mounting groove 11 at locations corresponding to the mounting plates 31. The openings of the evenly arranged cleaning holes 311 are directed toward the gaps between the mounting plates 31 and the locations of the mounting holes 36. The cleaning holes 311 are in communication with the cleaning chamber 13 provided in the side walls of the mounting groove 11. The bottom of the cleaning chamber 13 is in communication with an exhaust device, and a filter is provided on the inner wall of the cleaning chamber 13 between the cleaning holes 311 and the exhaust device. The exhaust device here can be an air pump device.

[0057] The mounting plate 31 is provided with an air inlet 312, which is located on both sides of the chute 34. A filter is provided at the top opening of the air inlet 312, and a control valve is provided inside to control the opening and closing of the air inlet 312.

[0058] The side wall of the mounting hole 36 is provided with a purification chamber 37, which communicates with the side wall of the air inlet 312 through a transmission channel 372. The side wall of the mounting hole 36 is evenly provided with purification holes 371, and the purification holes 371 point to the surface of the fixing member 362 inside the mounting groove 11;

[0059] Specific workflow: Based on the specific workflow of Example 3, inside the power station, during the lifting process of the mounting plates 31, they are separated from the mounting slots 11 and exposed to the outside world. Dust and moisture inside the power station may enter the gaps between the mounting plates 31 and then enter the mounting slots 11, affecting the dry and clean environment inside the mounting slots 11.

[0060] Therefore, a cleaning chamber 13 is provided inside the mounting groove 11. When the inspection is completed and the mounting plates 31 are returned to the mounting groove 11, the exhaust device inside the cleaning chamber 13 can be activated to extract the air in the gap and the mounting hole 36 through the adjacent cleaning holes 311, thereby removing dust and impurities adhering to the gap of the mounting plate 31 and the surface of the fixing member 362, thereby ensuring normal operation.

[0061] Specifically, after the air extraction device is started, negative pressure is generated in the gap, and the control air valve provided at the air inlet 312 is opened, so that the air inlet 312 is opened, and the external air flow is replenished into the gap through the air inlet 312, forming a continuous air flow flowing horizontally toward the cleaning hole 311, which can flush the surface of the gap and the dust and impurities adhered to the detection rod 35, and bring the fallen dust and impurities into the cleaning chamber 13; at the same time, part of the air flow will enter the purification chamber 37 through the transmission channel 372, and then flow out through the purification hole 371 to flush the surface of the fixing member 362 inside the mounting hole 36, so that the dust and impurities adhered to the surface of the fixing member 362 fall off, ensuring the normal adsorption and fixing function of the fixing member 362;

[0062] Furthermore, for the more sophisticated safety sensor 22 installed on the bottom mounting plate 31, since the downward airflow can only flow in through the air inlet 312 on the multi-layer mounting plate 31, the incoming airflow is filtered by the filter multiple times to ensure that the incoming airflow is sufficiently clean, which has less impact on the precision sensor at the bottom with poor anti-interference ability; and when the bottom mounting plate 31 is used less frequently, the air inlet 312 leading to the position of the precision sensor in the gap of the bottom mounting plate 31 can be closed, and by closing the corresponding control valve, the airflow is prevented from entering the gap of the bottom mounting plate 31, thereby reducing the adverse effects on the precision safety sensor 22, thereby achieving better preservation and reducing the probability of its failure. Example

[0063] On the basis of the fourth embodiment, the positioning plate 4 includes a closing plate 41 and a limiting plate 42. The closing plate 41 is mounted on the upper side of the limiting plate 42, and the closing plate 41 and the limiting plate 42 are rotatably connected. A rotating motor is provided at the rotating connection portion and is controlled by the intelligent control center. The sensing chip is mounted on the limiting plate 42, and the closing plate 41 is normally located on the upper side of the limiting plate 42, thereby protecting the limiting plate 42 from possible adverse effects of external impacts such as trampling on the limiting plate 42. A clamping block 43 is provided at the end of the closing plate 41. The end of the clamping block 43 extends upward, and the surface is coated with fluorescent paint to prevent pedestrians from being tripped by inattentive pedestrians.

[0064] The bottom of the vehicle body 1 is provided with a sensing groove 14, and the sensing sensor 12 is provided on the inner wall of the sensing groove 14; a card slot 15 is provided on the side wall of the sensing groove 14 at a position corresponding to the card block 43;

[0065] The clamping groove 15 is a tapered groove structure, and the clamping block 43 is embedded in the limiting hole 411 provided on the closing plate 41 through the limiting rod 431 provided at the end, and the limiting rod 431 and the limiting hole 411 are connected by a spring;

[0066] Specific working process: Based on the specific working process of the fourth embodiment, when the vehicle body 1 approaches the positioning plate 4 for inspection route positioning, the sensing slot 14 at the bottom of the vehicle body 1 is located on the upper side of the positioning plate 4, and then the rotating motor provided at the rotation connection portion of the closing plate 41 is started, driving the closing plate 41 to rotate relative to the limiting plate 42, and the closing plate 41 is changed from a horizontal state to a vertical state;

[0067] When the locking plate 31 is lifted, the locking plate 31 is locked and the locking plate 31 is locked.

[0068] Furthermore, the limit plate 42 is set around the important power equipment, so that the power equipment can be directly inspected while correcting the inspection route; and the cooperation between the closing plate 41 located at the bottom of the vehicle body 1 and the card slot 15 further ensures that the vehicle body 1 remains stable during the inspection process, so that the inspection work of the power station can be carried out smoothly.
