Description

[0002] In recent years, with the advancement of smart grids and the development of information technology and artificial intelligence, the level of intelligence in power systems has been increasing. The safe operation of excitation switchgear in the distribution room directly affects users' electricity consumption. However, traditional manual inspection methods are time-consuming and labor-intensive, and the inspection quality is greatly affected by subjective factors such as the inspector's knowledge level and mental state. At the same time, due to the complex environment and poor working conditions of the excitation switchgear, manual inspection poses many safety hazards. To facilitate staff's understanding of the status of the distribution room and to respond quickly to situations that occur, existing technologies mostly use distribution room inspection robots or track inspection devices equipped with power equipment detectors, sensors, control modules, and power modules to inspect high-voltage distribution room switchgear. However, most existing inspection robots or track inspection devices are either stationary or placed on the ground, making it difficult for staff to walk in the distribution room and increasing the risk of tripping or knocking over the inspection robots.

They are only for the purpose of simplifying the description of this invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] Example 1:

[0026] like Figures 1-6As shown, the safety inspection system for a track-mounted excitation rectifier cabinet provided by the present invention includes: a top track 20, an inspection crane, a visual inspection mechanism, and a smoke inspection mechanism; multiple suspension rods 46 for suspension installation are installed at intervals on the top surface of the top track 20; the inspection crane is movably installed on the top track 20; the visual inspection mechanism is installed on the inspection crane and is used to collect images and infrared images of the excitation rectifier cabinet; the smoke inspection mechanism is installed on the visual inspection mechanism and is used to detect the smoke concentration on the upper side of the excitation rectifier cabinet; a control box 1 is installed on the inspection crane; the control box 1 contains a controller, a memory, and a WiFi communication module; the memory and the WiFi communication module are both electrically connected to the controller; the inspection crane, the visual inspection mechanism, and the smoke inspection mechanism are all driven and controlled by the controller; an audible and visual alarm 2 electrically connected to the controller is installed on the control box 1.

[0027] By utilizing the overhead crane and the top track 20, the safety inspection system can be installed on the ceiling of the power distribution room, achieving a suspended installation, reducing the complexity of the power distribution room floor layout, and improving the work safety of the staff. The system uses visual inspection and smoke detection mechanisms to collect images, infrared images, and smoke information from above for each excitation rectifier cabinet. The controller stores the information in its memory. Every once in a while, the controller uploads the data in the memory to the remote control center via the WiFi communication module, helping the remote control center monitor the panel data and safety status of the excitation rectifier cabinet. At the same time, the controller can receive instructions from the remote control center or send signals to the remote control center via the WiFi communication module.

[0028] Furthermore, it also includes a battery module 5; a power supply module for power supply is provided in the control box 1; a replacement slot 3 is provided on one vertical side wall of the control box 1; the battery module 5 is inserted into the replacement slot 3; a mating terminal is provided in the replacement slot 3 for conductive contact with the power supply terminal of the battery module 5, and the mating terminal is electrically connected to the power supply module; the controller monitors the voltage of the battery module 5 through a voltage acquisition circuit; a pull handle 6 is installed on the battery module 5; a top-pressure positioning bolt 4 with its end extending into the replacement slot 3 is threadedly installed on the control box 1, and the extended end of the top-pressure positioning bolt 4 is tightly pressed against the battery module.

[0029] The top-pressure positioning bolt 4 is used to position the battery module 5 in the replacement slot, ensuring the reliability of the conductive contact between the docking terminal and the conductive terminal; the pull handle 6 is used to facilitate the picking and putting of the battery module 5; the controller monitors the power of the battery module 5 through the voltage acquisition module. When the power of the battery module 5 is lower than the preset value, the controller controls the inspection crane to return to the starting point of the top track 20 and sends a low power signal to the remote control center through the WiFi communication module, waiting for the battery module to be replaced.

[0030] Furthermore, the inspection crane includes a walking drive mechanism, a drive connecting rod 45, and two movable seats 21; the movable seats 21 are U-shaped seats; the two ends of the drive connecting rod 45 are respectively hinged to the two movable seats 21.

[0031] Two travel slots 23 are provided along the length direction on both the upper and lower sides of the top track 20, and the two travel slots 23 on the same side extend to the two vertical sides respectively; two sets of travel rollers 22 are rotatably installed on the two opposite inner sides of the movable seat 21; the four sets of travel rollers 22 travel on the four travel slots 23 respectively; a mounting base 7 is provided on the lower side of one movable seat 21; the control box 1 is mounted on the mounting base 7, and the visual inspection mechanism is mounted on the lower side of another movable seat 21; the travel drive mechanism is mounted on the mounting base 7, used to drive the movable seat 21 to travel along the top track 20, and is driven and controlled by the controller.

[0032] The cooperation between the two movable seats 21 and the drive connecting rod 45 enables the inspection crane to cooperate with the curved top track 20, facilitating the turning of the inspection crane; the cooperation between the four sets of traveling rollers 22 and the four traveling slots 23 realizes the movable installation of the movable seats 21.

[0033] Furthermore, the walking drive mechanism includes a lateral limiting unit, a walking drive motor 17, and a gear and rack transmission pair; the gear and rack transmission pair includes a walking drive gear 18 and a walking drive rack 19; the lateral limiting unit is mounted on the mounting base 7; the walking drive rack 19 is mounted along the length direction on one vertical side of the top track 20; the walking drive gear 18 is rotatably mounted on the lateral limiting unit and meshes with the walking drive rack 19; a limiting roller 24 is rotatably mounted on the lateral limiting unit, which travels on another vertical side of the top track 20, and the limiting roller 24 clamps the top track 20 relative to the walking drive gear 18; the clamping force between the walking drive gear 18 and the limiting roller 24 is adjusted by the lateral limiting unit; the walking drive motor 17 is used to drive the walking drive gear to rotate and is electrically connected to the controller through the walking drive circuit.

[0034] The travel drive motor 17 drives the travel drive gear 18 to rotate under the control of the controller. The travel drive gear 18 travels on the travel drive rack 19, realizing the movement of the moving seat 21 on the top track 20. This ensures the transmission reliability of the gear and rack transmission pair. At the same time, the travel drive gear 18 cooperates with the limit roller 24 to horizontally clamp the top track 20, which can play a certain role in preventing the inspection crane from tilting.

[0035] Furthermore, the lateral limiting unit includes a limiting adjustment seat 8, a limiting moving seat 9, a limiting adjustment bolt 11, and a limiting adjustment spring 15; a limiting adjustment channel is horizontally provided on the mounting base 7; the limiting adjustment seat 8 slides horizontally through the limiting adjustment channel; an anti-slip groove is provided on the limiting adjustment seat 8; an anti-slip slider that slides with the anti-slip groove is provided on the inner wall of the limiting adjustment channel; a travel drive gear 18 is rotatably mounted on the limiting adjustment seat 8; an adjusting groove 12 is provided on the through end of the limiting adjustment seat 8; and an adjusting spring 15 is provided in the middle of the adjusting groove 12. A retaining ring 14; one end of the limiting moving seat 9 slides into the adjusting groove 12; a limiting roller 24 is rotatably mounted on the limiting moving seat 9; a limiting adjusting bolt 11 is threaded through the limiting moving seat 9, with its end extending into the adjusting groove 12 and sliding through the adjusting retaining ring 14; an adjusting baffle 16 is installed on the extended end of the limiting adjusting bolt 11; a limiting adjusting spring 15 is sleeved on the limiting adjusting bolt 11 and elastically supported between the adjusting retaining ring 14 and the adjusting baffle 16; an anti-loosening nut 10 is threaded onto the limiting adjusting bolt 11 for preventing loosening.

[0036] The distance between the adjusting baffle 16 and the adjusting ring 14 is adjusted by turning the limiting adjusting bolt 11, thereby adjusting the elasticity of the limiting adjusting spring 15 by adjusting the compression degree of the limiting adjusting spring 15, so as to adjust the clamping force between the traveling drive gear 18 and the limiting roller 24, ensuring that the traveling drive gear 18 has a certain degree of mobility and reliable transmission when the inspection crane turns.

[0037] Furthermore, several electronic tags 27 are installed on the lower side of the top track 20; each electronic tag 27 is used to correspond to the position of each excitation rectifier cabinet; a card reader 26 for reading each electronic tag 27 is installed on the movable seat 21 with the visual inspection mechanism via an extension rod 25, and the card reader 26 is electrically connected to the controller.

[0038] The electronic tag 27 is used to correspond to the position of each excitation rectifier cabinet to facilitate the positioning of the inspection crane. After the card reader 26 reads the electronic tag 27, it controls the inspection crane to stop moving and the visual inspection mechanism to collect images.

[0039] Furthermore, the visual inspection mechanism includes a lifting adjustment unit, an infrared camera 35, and a high-definition camera 36; the upper end of the vertical adjustment unit is mounted on the movable base 21; both the infrared camera 35 and the high-definition camera 36 are mounted on the lifting adjustment unit and are electrically connected to the controller; a supplementary light 38 is installed on the lifting adjustment unit, and an electric control switch electrically connected to the controller is connected in series on the power supply line of the supplementary light 38; the lifting adjustment unit drives the infrared camera 35, the high-definition camera 36, ​​and the supplementary light 38 to rise and fall, and the lifting adjustment unit is driven and controlled by the controller.

[0040] Infrared camera 35 is used to acquire infrared images of the excitation rectifier cabinet, and high-definition camera 36 is used to acquire images of the excitation rectifier cabinet and its panel. The remote control center can decide whether to activate the supplementary light 38 based on the brightness and clarity of the uploaded images. The remote control center sends an activation command or a deactivation command to the controller via the WiFi communication module. After receiving the activation command, the controller controls the supplementary light 38 to be powered on and lit every time an image is acquired, which can provide supplementary lighting in the dimly lit power distribution room and improve image clarity. After receiving the deactivation command, the controller controls the supplementary light 38 to remain powered off to prevent overexposure. The height of the infrared camera 35 and the high-definition camera 36 can be adjusted by the vertical adjustment unit to achieve overall image acquisition of the excitation rectifier cabinet from top to bottom, ensuring the integrity of the acquired information.

[0041] Furthermore, the lifting adjustment unit includes a lifting column 28, a lifting adjustment tube 37, and a lifting drive motor 31; the upper end of the lifting column 28 is fixed to the lower side of the movable seat 21; the lifting adjustment tube 37 is slidably sleeved on the lifting column 28; a driving elongated hole 29 is vertically provided on the lifting column 28; a lifting drive screw 30 is rotatably installed inside the lifting column 28; the lifting drive motor 31 is used to drive the lifting drive screw 30 to rotate, and is electrically connected to the controller through the lifting drive circuit; a lifting drive block 33 is vertically slidably installed inside the lifting column 28, and the lifting drive block 33 is connected and fixed to the lifting adjustment tube 37 through a connecting block 32 that passes through the driving elongated hole 29; the lifting drive screw 30 is threadedly screwed through the lifting drive block 33; a horizontal mounting plate 34 is installed on the lifting adjustment tube 37; an infrared camera 35, a high-definition camera 36, ​​and a supplementary light 38 are all installed on the horizontal mounting plate 34; a smoke detection mechanism is installed on the upper side of the lifting column 28.

[0042] The lifting drive motor 31 drives the lifting drive screw to rotate under the control of the controller, so that the lifting drive block 33 drives the lifting adjustment tube 37 to move vertically through the connecting block 32 that passes through the drive elongated hole 29. This causes the horizontal mounting plate 34 to drive the infrared camera 35, the high-definition camera 36 and the fill light 38 to move vertically, thereby achieving height position adjustment.

[0043] The upper end of the pre-set lifting column 28 is the initial position of the lifting adjustment tube 37. Different height positions and numbers of image acquisition points are set according to different excitation rectifier cabinets. At least one image acquisition point corresponds to the panel position of the excitation rectifier cabinet. The height data of each image acquisition point of the corresponding excitation rectifier cabinet is stored by electronic tag 27. After the controller reads the electronic tag 27 through the card reader 26, it controls the lifting drive motor 31 to operate according to the height data of each image acquisition point recorded by the electronic tag 27. During the downward movement of the lifting adjustment tube 37, whenever the lifting adjustment tube 37 drives the infrared camera 35 and the high-definition camera 36 to an image acquisition point, the controller controls the lifting drive motor 31 to stop operating for a period of time and controls the infrared camera 35 and the high-definition camera 36 to acquire infrared images and images of the excitation rectifier cabinet. After the acquisition of the last image acquisition point is completed, the controller controls the lifting drive motor 31 to operate, so that the lifting adjustment tube 37 moves upward back to the initial position.

[0044] Furthermore, the smoke inspection mechanism includes a detection cantilever 39 and two smoke detection units; each smoke detection unit includes a gas flow pipe 43, a main collection hood 42, a top collection hood 41, and a smoke sensor 40; the proximal end of the detection cantilever 39 is fixed to the upper side of the lifting column 28, and the distal end extends to the top of the excitation rectifier cabinet; the gas flow pipe 43 is horizontally installed on the distal end of the detection cantilever 39, and its axis is parallel to the travel direction of the inspection crane; a gas flow window 44 is provided on the circumferential side wall of the gas flow pipe 43; the converging port of the main collection hood 42 is connected to the end of the gas flow pipe 43, and the collection port is tilted downwards to collect smoke drifting from the upper side of the excitation rectifier cabinet; the top collection hood 41 is connected to the top surface of the main collection hood 42 and is located on one side of the converging port; the smoke sensor 40 is installed on the top collection hood 41, and the detection end is located inside the top collection hood 41; the smoke sensor 40 is electrically connected to the controller.

[0045] The smoke sensor 40 detects the smoke concentration in real time. When the smoke concentration exceeds the preset threshold, the controller controls the inspection crane to stop moving and sends a fire alarm signal to the remote control center via the WiFi communication module. The controller also controls the audible and visual alarm 2 to emit audible and visual signals to indicate the location. The structure and installation of the gas flow pipe 43, the main collection hood 42, and the top collection hood 41 allow the airflow to pass through the collection port of the main collection hood 42, the top collection hood 41, the converging port of the main collection hood 42, the gas flow pipe 43, and the gas flow window 44 in sequence during the movement of the inspection crane, thus constructing an airflow channel. This ensures that the smoke can flow out through the airflow channel after entering the main collection hood 42, preventing the smoke from remaining inside the main collection hood 42 and affecting the detection accuracy.

[0046] Furthermore, it also includes a maintenance ladder 47; the upper end of the maintenance ladder 47 is mounted on the top track 20, and the lower end is supported on the ground. The maintenance ladder 47 facilitates climbing to the top track, making it convenient to replace the battery module 5 or the maintenance inspection crane.
