Description

Technical Field

[0001] This invention relates to the field of robotics, and more particularly to a substation robot. Background Technology

[0002] Substations require regular inspections to ensure equipment safety, reliability, and efficient operation. Introducing inspection robots during these inspections can significantly improve efficiency and safety. Inspection robots can automatically perform many repetitive and high-risk inspection tasks, greatly saving manpower. However, after implementing inspection robots, substations often operate unattended for extended periods. This can lead to the continuous accumulation of dust and other particulate contaminants, potentially affecting the safe operation of electrical equipment.

[0003] Installing a dust collection system in inspection robots can reduce dust or other particulate pollutants in the substation space. However, if the robot is left unattended for a long time, dust will continue to accumulate inside, making it impossible to guarantee the long-term stable operation of the inspection robot. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and title of the invention. Such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution;

[0007] Robots capable of solving substation dust problems include inspection robots and charging stations;

[0008] The inspection robot is equipped with a dust collection system, which has a dust collection box.

[0009] The dust collection box is connected to a channel, which serves as a dust discharge channel for discharging dust from the dust collection box. The dust discharge channel is equipped with a normally closed switch valve.

[0010] The charging station is equipped with a dust removal system;

[0011] The dust removal system includes an exhaust fan, a dust suction channel for absorbing dust, an external pipe for discharging dust to the outside, and a triggering mechanism for triggering the switching valve;

[0012] The exhaust fan's air inlet is connected to the dust extraction channel, and the exhaust fan's air outlet is connected to an external pipe.

[0013] The charging pile is equipped with a wireless power supply system, and the inspection robot is also equipped with a wireless charging system.

[0014] The wireless power supply system of the charging pile is equipped with a power supply induction coil, and the wireless charging system of the inspection robot is equipped with a charging induction coil.

[0015] It also includes a magnetic attraction system for charging piles and inspection robots;

[0016] The wireless power supply system of the charging pile works in conjunction with the wireless charging system of the inspection robot to start charging. The triggering mechanism on the charging pile triggers the opening of the switch valve on the inspection robot, connecting the dust exhaust channel and the dust suction channel. Then, the exhaust fan starts working and extracts the dust from the dust collection box through the dust suction channel and the dust exhaust channel, and discharges the dust through the external pipe.

[0017] The aforementioned design incorporates a dust removal system on the charging station. This system connects to a dust extraction channel, using a fan to suck up dust from the collection box and venting it to the outside through external pipes. The inspection robot automatically removes dust, preventing equipment malfunctions or fire risks caused by dust, thus improving overall safety and ensuring the long-term stable operation of the inspection robot. The wireless power supply system of the charging station and the wireless charging system of the inspection robot allow for charging without an exposed charging head, eliminating concerns about oxidation and dust accumulation, and improving the stability of the robot's long-term operation. Finally, a magnetic attraction system allows the charging station and the inspection robot to be magnetically attached together. This ensures stable charging for the robot, and when the magnetic system engages them, a trigger mechanism on the charging station opens a valve on the inspection robot, synchronizing the dust removal and charging docking processes. This enhances automation and ease of operation. After the inspection robot detaches from the charging station, the valve automatically closes, reducing the risk of dust leakage.

[0018] Preferably, the magnetic attraction system includes an annular iron sheet and an electromagnet system for attracting the annular iron sheet;

[0019] The annular iron sheet is installed in the inspection robot, and the outer end face of the annular iron sheet is located on the same side as the dust discharge opening that connects to the dust suction channel.

[0020] The annular iron sheet is concentrically arranged with the charging induction coil, and the annular iron sheet is arranged around the charging induction coil;

[0021] The electromagnet system includes an iron core, which is installed in the charging pile. One end of the iron core is connected to the dust extraction channel. The dust extraction port of the dust extraction channel is located on the same side wall of the charging pile.

[0022] The iron core is concentrically arranged with the power supply induction coil, and the iron core is arranged around the power supply induction coil;

[0023] The iron core and the annular iron sheet are at the same height and have matching cross-sectional shapes.

[0024] The charging station and inspection robot are positioned by attracting a ring-shaped iron plate using an electromagnet. When the inspection robot leaves the charging station, the power is cut off, causing the electromagnet to lose its magnetism and automatically separating. This facilitates the next docking or maintenance of the inspection robot and prevents metal powder from being attracted by the magnetic field, reducing cleaning workload and extending the equipment's lifespan. Reducing powder adsorption also improves positioning stability and enhances the normal operation of the inspection robot.

[0025] Preferably, the annular iron sheet is wrapped with a protective layer of polytetrafluoroethylene, the thickness of which is 1-2 mm; the wall thickness of the charging pile at the iron core is 2-3 mm.

[0026] The PTFE protective layer provides insulation, corrosion resistance, and wear resistance, extending its service life. The protective layer is 1-2mm thick, while the wall thickness at the iron core of the charging pile is 2-3mm. This ensures the stability of the magnetic force that attracts the annular iron sheet to the electromagnet.

[0027] Preferably, the dust extraction channel includes a main channel and a secondary channel, the main channel is connected to the secondary channel, the main channel is connected to the external pipe, and the secondary channel is connected to the dust exhaust channel;

[0028] The charging pile has a heat dissipation vent on the side opposite to the power supply induction coil, and the heat dissipation vent is directly facing the power supply induction coil.

[0029] The heat dissipation vent is connected to the main channel;

[0030] The charging pile has heat dissipation holes arranged on both sides.

[0031] By providing heat dissipation vents on the opposite side of the power supply induction coil, directly facing the coil, the exhaust fan can also draw air out of the charging pile when it is working. This effectively removes the heat generated during charging pile operation, enhances heat dissipation, ensures stable operation of the power supply induction coil, improves the long-term stability of the wireless charging system, and extends the service life of the inspection robot and the charging pile. The heat dissipation holes arranged on both sides of the charging pile improve air circulation within the charging pile, ensuring effective heat dissipation.

[0032] Preferably, two dust removal channels are provided, and two secondary channels are also provided. When the magnetic attraction system engages the charging pile and the inspection robot, the two secondary channels are respectively connected to the two dust removal channels. The diameter of the secondary channels is one-third to one-half the diameter of the main channel. The two dust removal channels are correspondingly connected to the two secondary channels to achieve efficient dust removal while maintaining the system's sealing and cleanliness.

[0033] Preferably, an infrared thermal switch is provided on the side of the charging pile, and the sensing direction of the infrared thermal switch is towards the power supply induction coil;

[0034] An electric switch door for opening and closing the heat dissipation vent is also provided between the heat dissipation vent of the charging pile and the main channel.

[0035] The infrared thermal switch controls the electric door switch.

[0036] An infrared thermal switch monitors the temperature changes of the power supply induction coil in real time. The switch controls the linkage to automatically adjust the electric door. When the internal temperature of the charging pile rises, the electric door opens, and hot air is drawn out through the main channel. The suction capacity of the secondary channel is reduced, ensuring heat dissipation while preventing dust from being stirred up and causing malfunctions due to dust accumulation inside the charging pile. Once the internal temperature returns to normal, the infrared thermal switch controls the electric door to close the main channel, and the suction capacity of the secondary channel increases, improving suction efficiency.

[0037] Preferably, the dust collection system includes a dust collection fan, and the air intake of the dust collection fan is connected to the dust collection box;

[0038] The air outlet of the vacuum cleaner is connected to the outside of the inspection robot;

[0039] A filter is also provided between the vacuum fan and the dust collection box, and the filter is located above the dust collection box;

[0040] The filter is equipped with a metal shell, and an ultrasonic generator is installed outside the filter;

[0041] The piezoelectric ceramic plate of the ultrasonic generator is disposed between the filter and the vacuum fan;

[0042] The ultrasonic waves emitted by the ultrasonic generator are directed through the metal casing toward the dust collection box.

[0043] Ultrasonic vibration can help dust escape from the filter more effectively, reduce filter clogging, and extend the lifespan of the vacuum system.

[0044] Preferably, at least four ultrasonic generators are arranged on the upper side of the dust collection box.

[0045] This is to enhance the effect of ultrasonic vibration, ensure higher filtration efficiency and more uniform vibration, which can help dust escape from the filter better and extend the service life of the dust collection system.

[0046] Preferably, an electromagnetic switch valve is also installed at the outlet of the external pipeline.

[0047] When the dust removal system stops working, the electromagnetic switch valve closes to prevent dust or moisture from entering the substation. When the dust removal system is working, the electromagnetic switch valve opens to facilitate dust removal.

[0048] Preferably, the charging pile is equipped with a rubber ring that covers the dust suction channel. The rubber ring improves the sealing performance when the dust suction channel and the dust discharge channel are connected, preventing dust leakage.

[0049] Preferably, the charging pile has two limiting blocks on both sides to block the inspection robot, and the opposite sides of the two limiting blocks have chamfers. This facilitates precise docking between the charging pile and the inspection robot. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0059] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in less than one implementation of the invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0060] Example 1

[0061] refer to Figures 1-5 The robot is equipped with the function of solving the dust problem in substations, including inspection robot 1 and charging pile 2.

[0062] The inspection robot 1 is equipped with a dust collection system, which has a dust collection box 3;

[0063] The dust collection box 3 is connected to a channel, which serves as a dust discharge channel 4 for discharging dust from the dust collection box 3. The dust discharge channel 4 is equipped with a normally closed switch valve 41.

[0064] Charging pile 2 is equipped with a dust removal system;

[0065] The dust removal system includes a fan 5, a dust suction channel 6 for absorbing dust, an external pipe for discharging dust to the outside, and a triggering mechanism 621 for triggering the switch valve 41.

[0066] The air intake of the exhaust fan 5 is connected to the dust suction channel 6, and the air outlet of the exhaust fan 5 is connected to an external pipe.

[0067] The charging pile 2 is equipped with a wireless power supply system, and the inspection robot 1 is also equipped with a wireless charging system.

[0068] The power supply system of the charging pile 2 is equipped with a power supply induction coil 8, and the charging system of the inspection robot 1 is equipped with a charging induction coil 7.

[0069] It also includes a magnetic attraction system for the charging pile 2 and the inspection robot 1;

[0070] The power supply system of charging pile 2 works in conjunction with the charging system of inspection robot 1 to start charging. The triggering mechanism 621 on charging pile 2 triggers the opening of the switch valve 41 on inspection robot 1, and the dust exhaust channel 4 is connected to the dust suction channel 6. Then the exhaust fan 5 starts working and extracts the dust from the dust collection box 3 through the dust suction channel 6 and the dust exhaust channel 4, and discharges the dust through the external pipe.

[0071] In the above design, the charging pile 2 is equipped with a dust removal system. It connects to the dust discharge channel 4 via the suction channel 6, using a fan 5 to suck up dust from the dust collection box 3 and discharge it to the outside through an external pipe. The inspection robot 1 automatically removes the dust, preventing equipment malfunctions or fire risks caused by dust, improving overall safety, and ensuring the long-term stable operation of the inspection robot 1. Through the wireless power supply system of the charging pile and the wireless charging system of the inspection robot, the inspection robot 1 can be charged without an exposed charging head, eliminating concerns about oxidation and dust accumulation on the exposed charging head, thus improving the stability of the inspection robot 1 during long-term operation. Finally, the magnetic attraction system can attract the charging pile 2 and the inspection robot 1 together, which can not only ensure the stability of the charging of the inspection robot 1, but also, after the magnetic attraction system attracts the charging pile 2 and the inspection robot 1, the trigger mechanism 621 on the charging pile 2 triggers the opening of the switch valve 41 on the inspection robot 1, so that the dust removal action and the charging docking are completed simultaneously, improving the level of automation and the convenience of operation. After the inspection robot 1 is separated from the charging pile 2, the switch valve 41 is separated from the trigger mechanism 621 and automatically closes, reducing the risk of dust leakage.

[0072] The magnetic attraction system includes an annular iron plate 71 and an electromagnet system for attracting the annular iron plate 71. The annular iron plate 71 is disposed in the inspection robot 1, and its outer end face is on the same side as the dust exhaust channel 4, which connects to the dust exhaust channel 6. The annular iron plate 71 is concentrically disposed with the charging induction coil 7 and is located around the charging induction coil 7. The electromagnet system includes an iron core 82, which is disposed in the charging pile 2. One end of the iron core 82 is on the same side wall of the charging pile 2, and its dust exhaust port is located on the same side wall as the dust exhaust channel 4. The iron core 82 is concentrically disposed with the power supply induction coil 8 and is located around the power supply induction coil 8. The iron core 82 and the annular iron plate 71 have the same height and matching cross-sectional shape. The charging pile 2 and the inspection robot 1 are engaged and positioned by an electromagnet attracting the annular iron plate 71. When the inspection robot 1 leaves the charging pile 2, the power is cut off, causing the electromagnet to lose its magnetism, thus automatically separating them. This facilitates the next docking or maintenance of the inspection robot 1 and prevents metal powder from being attracted under the magnetic field, reducing cleaning workload and extending the equipment's lifespan. Reducing powder adsorption also improves positioning stability and enhances the normal operation of the inspection robot 1.

[0073] The annular iron sheet 71 is wrapped with a protective layer of polytetrafluoroethylene (PTFE) with a thickness of 1-2 mm; the wall thickness of the charging pile 2 at the iron core 82 is 2-3 mm. The PTFE protective layer provides insulation, corrosion resistance, and wear resistance, extending its service life. The 1-2 mm thickness of the protective layer and the 2-3 mm wall thickness of the charging pile 2 at the iron core 82 ensure the stability of the magnetic force that attracts the annular iron sheet 71 to the electromagnet.

[0074] During operation, after the inspection robot 1's dust collection system finishes cleaning the substation, the dust is collected in the dust collection box 3. When the inspection robot 1 returns to the charging pile 2, the electromagnet system attracts the annular iron plate 71, thus connecting the charging pile 2 and the inspection robot 1. The trigger mechanism 621 on the charging pile 2 then triggers the opening of the switch valve 41 on the inspection robot 1, causing the dust collection channel 6 and the dust discharge channel 4 to operate synchronously with the charging connection. After the dust collection channel 6 and the dust discharge channel 4 are connected, the exhaust fan 5 operates to suck out the dust from the dust collection box 3 and discharges the dust to the outside through an external pipe. The inspection robot 1 automatically discharges dust, preventing equipment malfunctions or fire risks caused by dust, improving overall safety, and ensuring the long-term stable operation of the inspection robot 1. Through the power supply induction coil 8 of the charging pile 2 and the charging induction coil 7 of the inspection robot 1, the inspection robot 1 can be charged without an exposed charging head, eliminating concerns about oxidation and dust accumulation on the exposed charging head, further improving the stability of the inspection robot 1 during long-term operation.

[0075] Example 2

[0076] refer to Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0077] The dust extraction channel 6 includes a main channel 61 and a secondary channel 62. The main channel 61 is connected to the secondary channel 62, and the main channel 61 is connected to the external pipe. The secondary channel 62 is connected to the dust exhaust channel 4. A heat dissipation vent is provided on the side of the charging pile 2 opposite to the power supply induction coil 8, and the heat dissipation vent is directly facing the power supply induction coil 8. The heat dissipation vent is connected to the main channel 61. Heat dissipation holes 21 are arranged on both sides of the charging pile 2. By providing heat dissipation vents on the side opposite to the power supply induction coil 8, and directly facing the power supply induction coil 8, the exhaust fan 5 can also extract air from the charging pile 2 when it is working, effectively dissipating the heat generated during the operation of the charging pile 2, enhancing the heat dissipation effect, ensuring the stable operation of the power supply induction coil 8, improving the long-term stability of the wireless charging system, and extending the service life of the inspection robot 1 and the charging pile 2. The heat dissipation holes 21 arranged on both sides of the charging pile 2 improve air circulation within the charging pile 2, ensuring the heat dissipation effect.

[0078] Two dust removal channels 4 and two secondary channels 62 are provided. When the magnetic attraction system attracts the charging pile 2 and the inspection robot 1, the two secondary channels 62 are respectively connected to the two dust removal channels 4. The diameter of the secondary channel 62 is one-third to one-half the diameter of the main channel 61. The two dust removal channels 4 and the two secondary channels 62 are correspondingly connected to achieve efficient dust removal while maintaining the system's sealing and cleanliness.

[0079] An infrared thermal switch 10 is installed on the side of the charging pile 2, with its sensing direction facing the power supply induction coil 8. An electric switch door 9 for opening and closing the heat dissipation vent of the charging pile 2 is also installed between the heat dissipation vent and the main channel 61. The infrared thermal switch 10 controls and connects to the electric switch door 9. The infrared thermal switch 10 monitors the temperature change of the power supply induction coil 8 in real time, and controls the linkage to automatically adjust the electric switch door 9. When the internal temperature of the charging pile 2 rises, the electric switch door 9 opens, and the charging pile 2 draws out hot air through the main channel 61. The suction capacity of the secondary channel 62 is also reduced, ensuring heat dissipation for the charging pile 2 while preventing dust from being stirred up and causing dust accumulation inside the charging pile 2, thus preventing malfunctions. After the internal temperature of the charging pile 2 drops to a normal range, the infrared thermal switch 10 controls the electric switch door 9 to close the main channel 61, and the suction capacity of the secondary channel 62 increases, improving suction efficiency.

[0080] The dust collection system has a dust collection fan 11, and the air intake of the dust collection fan 11 is connected to the dust collection box 3;

[0081] The air outlet of the vacuum cleaner 11 is connected to the outside of the inspection robot 1. A filter 12 is also provided between the vacuum cleaner 11 and the dust collection box 3, and the filter 12 is located above the dust collection box 3. The filter 12 is equipped with a metal shell, and an ultrasonic generator is installed outside the filter 12. The piezoelectric ceramic plate of the ultrasonic generator is located between the filter 12 and the vacuum cleaner 11. The ultrasonic waves emitted by the ultrasonic generator are directed towards the dust collection box 3 through the metal shell. The ultrasonic vibration can help dust to be better removed from the filter 12, reduce filter clogging, and extend the service life of the vacuuming system.

[0082] At least four ultrasonic generators are arranged on the upper side of the dust collection box 3. This is to enhance the effect of ultrasonic vibration, ensure higher filtration efficiency and more uniform vibration, which can help dust to be better removed from the filter 12 and extend the service life of the dust collection system.

[0083] An electromagnetic switch valve is also installed at the outlet of the external pipeline. When the dust removal system stops working, the electromagnetic switch valve closes to prevent dust or moisture from entering the substation. When the dust removal system is working, the electromagnetic switch valve opens to facilitate dust removal.

[0084] The charging pile 2 is equipped with a rubber ring that covers the dust suction channel 6. The rubber ring improves the sealing performance when the dust suction channel 6 and the dust discharge channel 4 are connected, preventing dust leakage.

[0085] The charging pile 2 has two limiting blocks on both sides to block the inspection robot 1, and the opposite sides of the two limiting blocks are chamfered to facilitate precise docking between the charging pile 2 and the inspection robot 1.

[0086] In use, heat dissipation vents are provided on the opposite side of the power supply induction coil 8, directly facing the power supply induction coil 8. When the exhaust fan 5 is working, it can also draw air out of the charging pile 2, effectively removing the heat generated during operation, enhancing heat dissipation, ensuring the stable operation of the power supply induction coil 8, improving the long-term stability of the wireless charging system, and extending the service life of the inspection robot 1 and the charging pile 2. Heat dissipation holes 21 arranged on both sides of the charging pile 2 improve air circulation within the charging pile 2, ensuring heat dissipation. Two dust removal channels 4 are connected to two secondary channels 62 to achieve efficient dust removal while maintaining the system's sealing and cleanliness. An infrared thermal switch 10 monitors the temperature change of the power supply induction coil 8 in real time. The infrared thermal switch 10 controls the linkage to automatically adjust the electric door 9. When the internal temperature of the charging pile 2 rises, the electric door 9 opens, and the charging pile 2 draws out hot air through the main channel 61. The suction capacity of the secondary channel 62 is also reduced, ensuring heat dissipation for the charging pile 2 while preventing dust from being stirred up and causing dust accumulation inside the charging pile 2, thus preventing malfunctions. After the internal temperature of the charging pile 2 drops to the normal range, the infrared thermal switch 10 controls the electric switch door 9 to close the main channel 61, increasing the suction capacity of the secondary channel 62 and improving suction efficiency. Ultrasonic vibration helps dust to better detach from the filter 12, reducing filter clogging and extending the service life of the vacuuming system.

[0087] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
