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 is 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 equipped with power equipment detectors, sensors, control modules, batteries, and power modules to inspect high-voltage distribution room switchgear. However, most existing inspection robots use built-in batteries, which need to be recharged when the battery is low. Charging takes a lot of time, during which the equipment cannot continue to inspect the distribution room. Furthermore, for equipment with removable batteries, manual replacement is cumbersome.

[0025] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] In the description of this invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0028] Example 1:

[0029] like Figure 1-8 As shown, the present invention provides a status inspection system for excitation switchgear, comprising: a control box 8, an inspection guide rail 1, an inspection vehicle, a storage battery 30, a replacement and charging device, and an image acquisition device.

[0030] Several lifting feet 2 are spaced apart on the lower side of the inspection guide rail 1; the inspection vehicle travels along the inspection guide rail 1; the control box 8 is mounted on the inspection vehicle; the battery 30 is mounted on the control box 8 through a battery mounting mechanism and is powered by a power module; a replacement charging device is located on one side of the inspection guide rail 1, used to replace the battery 30 for the battery mounting mechanism and to charge the replaced battery 30; an image acquisition device is mounted on the inspection vehicle, used to acquire images of the excitation switch cabinet control panel; the control box 8 contains a main controller, a memory, a WiFi communication module, and a main Bluetooth communication module; the memory, WiFi communication module, and All main Bluetooth communication modules are electrically connected to the main controller; the main controller is electrically connected to the battery 30 through a voltage acquisition circuit; the inspection vehicle and the image acquisition device are both driven and controlled by the main controller; a slave controller and a slave Bluetooth communication module electrically connected to the slave controller are installed in the replacement charging device; the slave Bluetooth communication module communicates wirelessly with the main Bluetooth communication module; the replacement charging device is controlled by the slave controller; multiple electronic tags 56 are installed on the inspection guide rail 1, and each electronic tag 56 corresponds to the position of each excitation switch cabinet; a card reader 55 for reading the electronic tags 56 is installed on the inspection vehicle, and the card reader 55 is electrically connected to the main controller.

[0031] Inspection rail 1 is laid according to the setup of the excitation switchgear, and electronic tags corresponding to the location of each excitation switchgear are installed on the inspection rail 1. The electronic tags store the model of the excitation switchgear. Different image acquisition positions are set according to different models. The inspection vehicle moves with the image acquisition device. Whenever the card reader 55 reads the electronic tag 56, the inspection vehicle stops moving, and the image acquisition device adjusts the image acquisition position according to the read model, thereby acquiring images of the control panel of the excitation switchgear. After the acquisition is completed, the inspection vehicle continues to move until the card reader 55 reads the next electronic tag 56. This enables unmanned inspection of a large number of excitation switchgears, eliminating the need for personnel to walk to the excitation switchgear to read data one by one. The acquired image data is stored in the memory. The main controller uploads the data in the memory to the remote control center in real time via the WiFi communication module, facilitating timely information processing by the remote control center. Wireless communication between the main controller and the slave controller is achieved through the slave Bluetooth communication module and the main Bluetooth communication module, enabling the slave controller to receive commands from the main controller. The main controller monitors the battery level of the 30 through the voltage acquisition circuit. When the level is lower than the preset value, it controls the inspection vehicle to move to the battery replacement and charging device. The battery installation mechanism works with the slave controller to replace the battery 30. This eliminates the need for manual battery replacement, and the battery replacement time is much shorter than direct charging. It can monitor a large number of excitation switchgear for a long time, saving time and effort.

[0032] Furthermore, the inspection vehicle includes two traveling seats 4, a movable link 7, and a travel drive device; the traveling seats 4 are U-shaped; both traveling seats 4 are slidably mounted on the inspection guide rail 1; travel slots 3 are provided on the upper and lower sides of the two vertical sides of the inspection guide rail 1 along the direction; multiple traveling wheels 6 are rotatably mounted on the upper and lower sides of the two opposite inner sides of the traveling seats 4, and the traveling wheels 6 on the upper and lower sides of the same inner side travel on the upper and lower travel slots 3 on the corresponding vertical sides of the inspection guide rail 1, respectively; the two ends of the movable link 7 are movably mounted on the two traveling seats 4 respectively; the travel drive device is mounted on one traveling seat 4 to drive the traveling seat 4 to move along the inspection guide rail 1; the control box 8 is mounted on the travel drive device; the image acquisition device is mounted on the other traveling seat 4; an extension rod 54 is mounted on one traveling seat 4; and a card reader 55 is mounted on the extension rod 54.

[0033] By utilizing the cooperation between the walking slot 3 and the walking wheel 6, the walking seat 4 is slidably installed on the inspection guide rail 1, while reducing friction and improving movement stability; by utilizing the installation method at both ends of the movable connecting rod 7, the traction connection between the two walking seats 4 can be realized, enabling the two walking seats 4 to pass through bends.

[0034] Furthermore, the walking drive device includes a positioning seat 9, a clamping adjustment structure, a walking drive motor 11, and a walking gear rack pair; the walking gear rack pair includes a walking drive gear and a walking drive rack; the clamping adjustment structure includes a telescopic outer tube 10, a telescopic inner threaded tube 12, and a telescopic adjustment bolt 15.

[0035] The positioning seat 9 is fixed on the traveling seat 4; the control box 8 is installed on the upper side of the positioning seat 9; the telescopic outer tube 10 slides through the positioning seat 9; a clamping limiting groove is provided on the upper side of the telescopic outer tube 10 along the sliding direction; a clamping limiting slider that slides along the clamping limiting groove is provided on the positioning seat 9; the traveling drive motor 11 is installed on one end of the telescopic outer tube 10 and is electrically connected to the main controller through the traveling drive circuit; one end of the telescopic inner threaded tube 12 is telescopically inserted into the other end of the telescopic outer tube 10; the telescopic adjusting bolt 15 is threaded... The telescopic internal threaded tube 12 is attached to the other end; a telescopic locking nut 16 for preventing loosening is screwed onto the telescopic adjusting bolt 15; a telescopic adjusting rod 20 extending into the telescopic outer tube 10 is connected to the mounting end of the telescopic adjusting bolt 15; a clamping support plate 18 is provided on the extension end of the telescopic adjusting rod 20; a clamping support ring is provided on the inner wall of the telescopic outer tube 10 through which the telescopic adjusting rod 20 passes; a clamping drive spring 19 is sleeved on the telescopic adjusting rod 20 and supported between the clamping support plate 18 and the clamping support ring.

[0036] The travel drive rack is mounted on the inspection guide rail 1 along the direction; the travel drive gear is mounted on the output shaft of the travel drive motor 11 and meshes with the travel drive rack; a clamping shaft 13 is fixed on the telescopic internal thread tube 12; a clamping wheel 14, which is supported on the inspection guide rail 1, is rotatably mounted on the clamping shaft 13, and the clamping wheel 14 and one side of the travel drive gear extend into the travel seat 4 to clamp the inspection guide rail 1.

[0037] The walking drive motor 11, under the control of the main controller, drives the walking drive gear to rotate. The walking drive gear travels on the walking drive rack, realizing the movement of the walking seat 4 along the inspection guide rail 1. The clamping wheel 14, in cooperation with the walking drive gear, clamps the inspection guide rail 1, which can provide a certain anti-tipping effect for the walking seat 4. The clamping force between the clamping wheel 14 and the walking drive gear can be adjusted by the cooperation between the telescopic outer tube 10, the telescopic inner threaded tube 12, the clamping drive spring 19, and the telescopic adjustment bolt 15. By turning the telescopic adjustment bolt 15 to adjust the position of the telescopic adjustment rod 20, the clamping support plate 18 and the clamping support ring are compressed or relaxed, thereby adjusting the clamping force between the clamping wheel 14 and the walking drive gear. This ensures that the walking drive motor 11 can reliably transmit power and will not jam when the walking seat 4 passes any position on the inspection guide rail 1.

[0038] Furthermore, the battery mounting mechanism includes a battery mounting base 21 and a battery clamping branch; the battery mounting base 21 is fixed to the upper side of the control box 8; a battery mounting groove 28 is provided on the lower side of the battery mounting base 21; two power supply terminals 29 are provided on one inner wall of the battery mounting groove 28; two snap-fit ​​slots 34 are vertically provided on the battery 30; a clamping groove 50 is provided on the two opposite side walls of each snap-fit ​​slot 34; a conductive contact 33 is telescopically installed on each clamping groove 50, and the protruding edge of the conductive contact 33 is rounded; two clamping springs 51 are provided between the bottom of each clamping groove and the corresponding conductive contact 33; the two power supply terminals 29 extend into the two snap-fit ​​slots 34 respectively, and the conductive contact 33 in the two snap-fit ​​slots 34 clamps the corresponding power supply terminals 29; the two power supply terminals 29 are electrically connected to the power module; the conductive contact 33 in the two snap-fit ​​slots 34 are electrically connected to the two electrodes of the battery 30 respectively.

[0039] The battery clamping branch is mounted on the battery mounting base 21 and is used to position the battery 30 in the battery mounting slot 28.

[0040] The conductive contact 33 is driven to extend out of the clamping groove by the clamping spring 51, so that the two conductive contact 33 in the same snap-fit ​​slot 34 are relatively close to each other, clamping the power supply terminal 29 and ensuring the reliability of conductive contact. The rounded corners of the conductive contact 33 facilitate clamping the power supply terminal 29. The battery clamping branch is used to clamp and position the battery 30 to prevent the battery 30 from falling off.

[0041] Furthermore, the battery clamping branch includes a clamping guide seat 22, a clamping drive motor 23, a clamping drive screw 24, and two clamping drive bars 25;

[0042] The clamping guide seat 22 is U-shaped, and the opening of the clamping guide seat 22 is fixed on the upper side of the battery mounting seat 21; two clamping holes are provided on the two opposite vertical sides of the battery mounting seat 21; and two clamping slots 31 are provided on the battery 30, which correspond to the two clamping holes respectively.

[0043] Two clamping drive bars 25 are telescopically inserted into both ends of the clamping guide seat 22. Two clamping rods 5 are fixed on the two clamping drive bars 25. The lower sides of the two clamping rods 5 are bent relative to each other, and the two bent ends are inserted into the corresponding clamping slots 31 after passing through the two clamping holes. Two clamping guide holes 27 are provided on the clamping guide seat 22. A clamping drive seat 26 is fixed on each of the two clamping drive bars 25, and the two clamping drive seats 26 pass through the two clamping guide holes 27 and slide along the clamping guide holes 27. The clamping drive screw 24 is rotatably and horizontally installed on the upper side of the clamping guide seat 22, and its two ends are threaded through the two clamping drive seats 26 to drive the two clamping drive seats 26 to move relative to each other. The clamping drive motor 23 is installed on the clamping guide seat 22, drives the auxiliary drive clamping drive screw 24 to rotate through the bevel gear, and is electrically connected to the main controller through the clamping drive circuit.

[0044] Under the control of the controller, the clamping drive motor 23 drives the clamping drive screw 24 to rotate through the bevel gear pair, so that the two clamping drive seats 26 are relatively close or relatively far apart, and the two clamping drive bars 25 drive the two clamping rods 5 to be relatively close or far apart, so that the two bent ends extend into or detach from the two clamping slots 31, thereby realizing the clamping or release of the battery 30.

[0045] Furthermore, the replacement charging device includes a charging control box 41, a power receiving base 35, a translation switching mechanism, and a power lifting mechanism.

[0046] Both the controller and the Bluetooth communication module are located on the charging control box 41; a charging circuit is provided inside the charging control box 41; a charging support column 40 for positioning and installation is provided at the bottom of the charging control box 41; a switching positioning seat 42 is fixed on the charging support column 40; a power receiving seat 35 is horizontally slidably installed on the switching positioning seat 42; two charging slots 32 for storing the battery 30 are provided on the upper side of the power receiving seat 35; each charging slot 32 is equipped with a corresponding two snap-fit ​​slots 34. The battery has two charging terminals 17, which are electrically connected to the charging circuit. The charging circuit is connected to the mains power, and a second electronically controlled switch, which is electrically connected to the controller, is connected in series between the charging circuit and the mains power. The translation switching mechanism is used to drive the power receiving base 35 to slide horizontally, so that the two charging slots 32 correspond to the battery mounting slots 28 in sequence. The power lifting mechanism is installed on the power receiving base 35 and is used to lift the charged battery 30 into the battery mounting slots 28. The edges of the battery mounting slots 28 and the two charging slots 32 are all chamfered.

[0047] The translation switching mechanism adjusts the position of the power receiving seat 35 so that the empty charging slot 32 corresponds to the battery mounting slot 28 to receive the battery 30. After receiving, the translation switching mechanism controls the power receiving seat 35 to move so that another charging slot 32 containing the fully charged battery 30 corresponds to the position of the battery mounting slot 28. The power lifting mechanism lifts the fully charged battery 30 into the battery mounting slot 28. The replaced battery 30 is charged in the charging slot 32. After a period of time, the controller disconnects the power to the charging circuit through the second electronic control switch, thereby realizing the replacement and charging of the battery 30 without manual replacement, enabling the inspection system to perform long-term monitoring.

[0049] The translation drive motor 43 drives the translation drive screw 44 to rotate under the control of the controller, so that the translation drive seat 45 moves the power receiving seat 35. Two position sensors 47 help the controller determine the position of the power receiving seat 35. When one position sensor 47 detects the positioning plate 48, its corresponding charging slot 32 corresponds to the position of the battery mounting slot 28. At this time, the controller controls the translation drive motor 43 to stop running.

[0050] Furthermore, the power lifting mechanism includes two lifting branches; the lifting branches include a lifting drive motor 37 and a lifting outer tube 36;

[0051] One end of the lifting outer tube 36 is fixed to the lower side of the power supply receiving base 35 and corresponds to the position of the corresponding charging slot 32; a lifting inner thread tube 38 is vertically slidably inserted into the lifting outer tube 36, with its upper end extending into the corresponding charging slot 32; a lifting drive screw is rotatably and coaxially mounted inside the lifting outer tube 36, threaded onto the lifting inner thread tube 38; a lifting drive motor 37 drives the lifting drive screw to rotate through a lifting drive gear pair and is electrically connected to the slave controller through a lifting drive circuit; a lifting plate 39 is fixed to the extended end of the lifting inner thread tube 38; and a storage slot for accommodating the lifting plate 39 is provided in both charging slots 32.

[0052] Two lifting branches correspond to two charging slots 32.

[0054] The position of the acquisition base 59 is adjusted by the position adjustment mechanism, so that the camera 65 can capture control panel images of different locations and different models of excitation switch cabinets. This helps the remote control center to collect data of the excitation switch cabinets regularly, eliminating the need for staff to read the data one by one in front of the excitation switch cabinets, saving time and effort.
