[0002] The main disadvantage of traditional electrical fire DC fault arc monitoring and detection equipment in terms of maintenance is the inaccuracy of its fault location, which not only makes it difficult for maintenance personnel to find the specific location of the arc, but also causes the fire to spread due to the inability to respond quickly, missing the key window for early intervention. For example, in the electrical system of a high-rise building, traditional DC fault arc monitoring equipment can only indicate that a continuous arc occurs on the cable line on a certain floor, but it cannot be accurate to the specific cable segment or connection point. When maintenance personnel arrive at the scene, they have to check all cables and electrical equipment on the floor one by one. This process is not only time-consuming and labor-intensive, but also cannot respond quickly, increasing the risk of fire spreading. Utility Model Content

[0041] The following is combined with Figure 1-5 This application is described in further detail.

[0042] Reference Figure 1-2 A DC fault arc monitoring and detection device for electrical fires includes a mobile mechanism 1, a projection mechanism 2 connected to the mobile mechanism 1, and a detection mechanism 3 arranged on the projection mechanism 2, the detection mechanism 3 includes a regional positioning detection unit 31 connected to an actual cable and establishing a wireless connection with the mobile mechanism 1, and an arc point detection unit 32 electrically connected to the projection mechanism 2, a signal input end of the arc point detection unit 32 is electrically connected to the mobile mechanism 1, and a signal output end of the arc point detection unit 32 is electrically connected to the projection mechanism 2.

[0043] In this embodiment, the area positioning detection unit 31 is set on the wall 100. When the area positioning detection unit 31 detects an arc in the cable on the wall 100, it sends a signal to the mobile mechanism 1. When the mobile mechanism 1 moves to the projection and detection position corresponding to the wall 100, it sends a signal to the arc point detection unit 32 for detection for a certain period of time. After obtaining the specific location where the arc is generated, the specific location information of the corresponding arc is sent to the projection mechanism 2 for projection marking to facilitate maintenance personnel. The detection results are intuitively displayed through the projection mechanism 2, providing maintenance personnel with accurate fault location information, thereby simplifying the maintenance process, reducing operational risks, and greatly shortening the maintenance response time, effectively improving the safety of electrical fire prevention and control.

[0044] Specifically, the electrical fire DC fault arc monitoring and detection equipment achieves efficient fault location and visualization through its precise structural layout and wireless linear connection. The mobile mechanism 1 is equipped with a regional positioning detection unit 31, which is responsible for moving along the actual cable, monitoring and wirelessly sending the signal generated by the arc to the control center. Once an abnormality is detected, the mobile mechanism 1 quickly locates the fault area. At the same time, the arc point detection unit 32 is installed on the projection mechanism 2, and its signal input end receives the arc signal from the mobile mechanism 1, while the signal output end is connected to the projection mechanism 2 to receive detailed information. When the arc point detection unit 32 determines the precise position of the arc, it triggers the projection mechanism 2 to project the fault position in the form of a visual signal, guiding maintenance personnel to quickly and accurately find and handle arc faults, thereby greatly improving fault response speed and maintenance efficiency.

[0045] Preferably, the regional positioning detection unit 31 can be a fault arc detector, which is a professional safety monitoring device that identifies fault arcs by real-time analysis of current and voltage changes in electrical lines. These detectors use special spectral radiation signals generated during arc discharge and use specific algorithms for signal processing to determine the type, location and size of the arc, thereby issuing an alarm in a very short time to prevent fire or explosion hazards caused by it. They are suitable for various power systems, especially for the monitoring of cables, switches, transformers and other equipment in high-voltage circuits, and can significantly improve the safety and reliability of power systems.

[0046] Preferably, the arc point detection unit 32 can be an infrared thermal imaging element, an ultrasonic sensor that can detect high-frequency sound waves accompanying the generation of an arc, or an electromagnetic field detector that uses the electromagnetic waves generated by the arc for positioning; among them, the reasons for selecting the infrared thermal imaging element as the arc point detection unit 32 include high-temperature detection capability, because a large amount of heat is released when an arc is generated, and the infrared thermal imaging element can detect this high temperature, thereby quickly locating the fault point; non-contact, because the infrared thermal imaging element can detect without contacting the cable, and is suitable for high-voltage or dangerous electrical environments; real-time monitoring, because infrared thermal imaging technology can provide real-time temperature data and images, which helps to detect and respond to arc faults in a timely manner; penetration capability, because infrared radiation can penetrate some materials, such as smoke or plastic casings, so that the infrared thermal imaging element can still work effectively in complex environments; high-resolution imaging, because modern infrared thermal imaging elements provide high-resolution images, which helps to accurately identify the fault location.

[0047] Further, see Figure 1 A rotating seat 21 and a motor for driving the rotating seat 21 to rotate are rotatably provided on the top of the projection mechanism 2. The rotating seat 21 is connected to the arc point detection unit 32 so that the arc point detection unit 32 rotates with the rotation of the rotating seat 21.

[0048] In this embodiment, the technology realizes the all-round rotation of the arc point detection unit 32 by means of the rotating seat 21 and the driving motor arranged on the top of the projection mechanism 2, so that it can flexibly and accurately detect cables at different angles, and intuitively display the detection results through the projection mechanism 2, which greatly improves the flexibility of fault location and the efficiency of maintenance work.

[0049] Specifically, this technology realizes the positioning function of the arc point detection unit 32 by integrating the rotating seat 21 and the driving motor on the top of the projection mechanism 2. The rotating seat 21 is connected to the arc point detection unit 32 as a connecting component, so that the detection unit can rotate in all directions with the rotating seat 21 driven by the motor, thereby covering a wider detection range. When the detection unit receives the signal from the mobile mechanism 1 and determines the approximate location of the arc fault, the rotating seat 21 starts the motor for precise steering so that the detection unit is aligned with the fault area. In this way, the arc point detection unit 32 can scan the fault point in detail and transmit its position information to the projection mechanism 2, so as to realize the accurate projection of the fault location and guide the maintenance personnel to perform the maintenance tasks efficiently. The linkage operation of the entire system improves the flexibility and accuracy of arc fault detection and optimizes the maintenance response process.

[0050] Further, see Figure 1The rotating seat 21 is connected to the arc point detection unit 32 by providing a first flip structure 4. The first flip structure 4 includes a first fixed portion 41 connected to the rotating seat 21, and a first flip portion 42 connected to the arc point detection unit 32. The first flip portion 42 can be flipped relative to the first fixed portion 41 so that the detection end of the arc point detection unit 32 is flipped to align with the ground for detection.

[0051] In this embodiment, the first flip structure 4 designed between the rotating seat 21 and the arc point detection unit 32 allows the detection end of the detection unit to flip and align with the ground for detection when needed. This innovative structure not only enhances the flexibility and coverage of detection, but also improves the detection efficiency of the ground or wall 100 cable fault arc, and further optimizes the maintenance personnel's positioning of the fault point and the maintenance process.

[0052] Specifically, there may be cables underground. This technology enhances the positioning flexibility and detection range of the arc point detection unit 32 by setting a first flip structure 4. The fixed portion on the rotating seat 21 is connected to the flip portion of the arc point detection unit 32 through the first flip structure 4, allowing the detection unit to be adjusted in the horizontal and vertical directions. When it is necessary to detect cables on the ground or wall 100, the flip portion can be flipped relative to the fixed portion so that the detection end is accurately aligned with the target area. This design makes the arc point detection unit 32 not only limited to horizontal detection, but also can be adjusted to a vertical or inclined angle for detection according to actual needs, which greatly improves the adaptability and accuracy of the detection. After linkage, the motor drives the rotating seat 21 to rotate to the target position, and then the first flip structure 4 enables the detection unit to accurately point to the arc occurrence point, achieving efficient and accurate detection effects.

[0053] Further, see Figure 1 and 3 The electrical fire DC fault arc monitoring and detection device also includes an auxiliary positioning unit 6, which is connected to the rotating seat 21 through a second flip structure 5. The auxiliary positioning unit 6 is electrically connected to the mobile mechanism 1. The mobile mechanism 1 includes a mobile component 11 and a mobile control unit. The mobile control unit is used to control the mobile component 11 to move to a corresponding position according to a signal sent by the auxiliary positioning unit 6.

[0054] In this embodiment, the coordinated work of the auxiliary positioning unit 6 and the second flip structure 5 realizes the precise spatial positioning of the detection unit and the navigation of the mobile mechanism 1, ensuring that the mobile component 11 reaches the suspected fault area quickly and accurately, thereby improving the response speed and positioning accuracy of arc fault detection.

[0055] Preferably, for floor positioning and navigation in a room or an entire building, a comprehensive space system is usually required to achieve accurate spatial positioning of the detection unit and navigation of the mobile mechanism 1, so it can generally involve indoor positioning technology and 3D map technology. Indoor positioning technologies such as Wi-Fi, Bluetooth, infrared, ultra-wideband (UWB), RFID, ZigBee and ultrasound are existing mature technologies that can provide accurate positioning services in indoor environments where satellite signals cannot cover. Wi-Fi positioning uses the existing wireless network infrastructure to triangulate positioning by detecting signal strength; Bluetooth technology determines the position by communicating with beacons (such as iBeacon) and is suitable for small-scale positioning; infrared positioning relies on direct line-of-sight signal transmission between infrared transmitters and receivers; UWB achieves centimeter-level accurate positioning by measuring the time difference of radio pulses; RFID uses radio waves to identify and track tags; ZigBee performs short-range communication positioning through a mesh network; and ultrasound determines the distance by measuring the propagation time of sound waves in the air. Specifically, this technology achieves rapid and accurate positioning of the fault arc position through the combination of the auxiliary positioning unit 6 and the second flip structure 5. The auxiliary positioning unit 6 is responsible for sending signals to assist in determining the approximate position of the arc, and these signals are transmitted to the mobile control unit through an electrical connection. The mobile control unit then processes these signals and directs the mobile component 11 to move the detection device to the corresponding position of the arc occurrence area. The second flip structure 5 enables the auxiliary positioning unit 6 to flexibly adjust the detection angle to adapt to the detection needs of different heights and directions. When the mobile mechanism 1 reaches the predetermined position, the arc point detection unit 32 further performs detailed detection and transmits the detection results to the projection mechanism 2 for visual display. The collaborative work of the entire system greatly improves the monitoring efficiency of DC fault arcs, ensuring the rapidity of fault response and the accuracy of maintenance work;

[0056] 3D map technology is an advanced indoor navigation solution that enables users to intuitively understand complex building structures, including floors, stairs, elevators, and room layouts, by creating indoor maps with three-dimensional views. This technology is particularly suitable for large indoor environments such as shopping malls, airports, and hospitals. It not only improves the intuitiveness and accuracy of navigation, but also enhances the user's interactive experience. 3D map technology can achieve seamless integration of indoor and outdoor navigation, support cross-floor navigation, and provide additional value-added services by integrating business information. It is an indispensable part of smart building and smart city construction.

[0057] Further, see Figure 1 and 3A cable detection unit 7 is provided on the rotating seat 21, a signal input end of the cable detection unit 7 is electrically connected to the moving mechanism 1, a signal output end of the cable detection unit 7 is electrically connected to the projection mechanism 2, and the cable detection unit 7, the auxiliary positioning unit 6 and the arc point detection unit 32 are distributed circumferentially on the rotating seat 21 in sequence.

[0058] In this embodiment, the cable detection unit 7, the auxiliary positioning unit 6 and the arc point detection unit 32 are integrated on the rotating seat 21, and they are distributed circumferentially in sequence, thereby realizing comprehensive detection, precise positioning and intuitive projection of arc faults, optimizing the fault detection process and improving maintenance efficiency.

[0059] Specifically, the technology realizes comprehensive monitoring and precise positioning of DC fault arcs in electrical fires by integrating a cable detection unit 7, an auxiliary positioning unit 6 and an arc point detection unit 32 on a rotating seat 21. The cable detection unit 7 is responsible for detecting the cable status and transmitting the detection data to the mobile mechanism 1 through the signal input end to guide it to move to the suspected fault area. At the same time, its signal output end is connected to the projection mechanism 2 so as to transmit the precise fault location information determined by the arc point detection unit 32 to the projection mechanism 2. The auxiliary positioning unit 6 on the rotating seat 21 is assisted in positioning by the second flip structure 5 to further calibrate the fault location. When working in linkage, the mobile mechanism 1 moves the detection device to the optimal detection position according to the signal of the auxiliary positioning unit 6, the arc point detection unit 32 performs precise detection, and sends the results to the projection mechanism 2 through the cable detection unit 7 for intuitive display, thereby providing maintenance personnel with clear fault indications and optimizing the fault diagnosis and maintenance process.

[0060] Preferably, when the cable detection unit 7 is used as a radio frequency signal generator, it detects and locates the cable by emitting radio frequency signals of a specific frequency. When these signals encounter the cable, reflection or coupling phenomena will occur due to the conductive properties of the cable, forming detectable signal changes. The radio frequency signal generator is able to receive these changing signals and use the characteristics of the signal (such as propagation time, phase difference, frequency offset or signal strength) to infer the existence, location and direction of the cable. In addition, by analyzing the reflection pattern and strength of the signal, the state of the cable can also be evaluated and potential faults or damage can be detected. This technology is particularly suitable for determining the exact location of existing cables during construction, maintenance and repair or planning new cable routes to avoid damage to them during drilling or excavation.

[0061] Further, see Figure 4 The second flipping structure 5 includes a second fixing portion 51 connected to the rotating seat 21, and a second flipping portion 52 connected to the auxiliary positioning unit 6. The second flipping portion 52 can be flipped relative to the second fixing portion 51 so that the detection end of the auxiliary positioning unit 6 is flipped to align with the ground for detection.

[0062] In this embodiment, the design of the second flip structure 5 enables the auxiliary positioning unit 6 to be flexibly flipped and accurately aligned with the ground target, thereby enhancing the multi-angle detection capability of the detection equipment and improving the accuracy and flexibility of fault location.

[0063] Specifically, this technology enables the auxiliary positioning unit 6 to detect cables at different heights through the flexible design of the second flipping structure 5. The second fixed portion 51 is connected to the rotating seat 21 to provide a stable support point, and the second flipping portion 52 is connected to the auxiliary positioning unit 6 to allow it to flip relative to the fixed portion. When it is necessary to detect the ground cable, the second flipping portion 52 flips and adjusts the detection end of the auxiliary positioning unit 6 to a position vertically aligned with the ground to achieve precise positioning. During linkage operation, the signal emitted by the auxiliary positioning unit 6 is transmitted to the mobile control unit through an electrical connection, and the unit then controls the mobile component 11 to reach the specified position, while the arc point detection unit 32 performs detailed detection based on the information provided by the auxiliary positioning unit 6, and finally transmits the detection result to the projection mechanism 2 through the cable detection unit 7 to complete the precise projection of the fault position, thereby improving the accuracy of fault detection and the efficiency of maintenance.

[0064] Further, see Figure 4 The auxiliary positioning unit 6 includes a fixing member 61 connected to the second flipping portion 52 , a ball head connecting member 62 universally rotatably connected to the fixing member 61 , and a camera 63 connected to the ball head connecting member 62 .

[0065] In this embodiment, the combination of the ball head connector 62 and the camera 63 in the auxiliary positioning unit 6 realizes multi-directional flexible rotation and precise positioning of the camera 63, enhances the observation capability of the arc fault area, and improves the detection accuracy and maintenance convenience.

[0066] Specifically, this technology realizes flexible positioning and multi-angle detection of the camera 63 through the sophisticated structural design of the auxiliary positioning unit 6. The fixing member 61 is connected to the second flip part 52 to ensure that the camera 63 can be aimed at the detection target with the assistance of the flip mechanism; the universal rotation characteristics of the ball head connector 62 give the camera 63 a full range of rotational freedom, so that it can accurately point to and track the potential position of the fault arc; the image captured by the camera 63 is transmitted to the control unit through an electrical connection, thereby guiding the precise positioning of the mobile mechanism 1. When working in linkage, the flipping action of the second flip part 52 enables the auxiliary positioning unit 6 to adjust the angle of the camera 63 according to the detection requirements, and the ball head connector 62 allows the camera 63 to be fine-tuned and positioned, so as to achieve accurate detection and identification of the arc occurrence point, greatly improving the flexibility and accuracy of the detection system.

[0067] Further, see Figure 1 and 3 The moving assembly 11 includes a moving base 112 and an adjusting bracket 111 connected to the moving base 112 . The adjusting bracket 111 is connected to the projection mechanism 2 to adjust the position of the projection surface of the projection mechanism 2 .

[0068] In this embodiment, the design of the movable base 112 and the adjustment bracket 111 allows the projection surface position of the projection mechanism 2 to be flexibly adjusted, ensuring the accuracy and clarity of the projection effect, thereby optimizing the visualization process of fault indication and maintenance guidance.

[0069] Specifically, this technology realizes the precise positioning and height adjustment of the projection mechanism 2 through the innovative design of the mobile component 11. The mobile base 112 serves as the basis, carrying the entire mobile component 11 and providing a stable mobile platform; the adjustment bracket 111 is connected to the mobile base 112, and is connected to the projection mechanism 2 through a hinge or locking mechanism, allowing the projection mechanism 2 to be adjusted vertically or horizontally. After the mobile control unit determines the fault location according to the signal of the auxiliary positioning unit 6, it controls the mobile component 11 to guide the projection mechanism 2 to the target area. The adjustment bracket 111 plays a role in this process, enabling the projection mechanism 2 to adapt to the projection requirements of different heights and directions, ensuring that the projection surface is correctly aligned and covers the fault area. After linkage, the entire mobile component 11 works together, so that the projection mechanism 2 can be flexibly adjusted to the optimal position to clearly and accurately project the location of the fault arc, provide intuitive guidance for maintenance personnel, and improve the efficiency and accuracy of maintenance.

[0070] Further, see Figure 1 and 3 The adjustment bracket 111 includes a bottom plate 1111 rotatably matched with the movable base 112, a folding group rod 1112 hingedly matched with the bottom plate 1111, and a top plate 1113 hingedly matched with the folding group rod 1112 and connected to the projection mechanism 2. The folding group rod 1112 can be unfolded upward or folded downward to adjust the up and down movement of the projection mechanism 2.

[0071] In this embodiment, the design of the foldable adjustment bracket 111 enables flexible adjustment of the height of the projection mechanism 2, which is convenient for adapting to projection requirements at different heights and enhances the applicability and operational convenience of the device.

[0072] Specifically, this technology achieves flexible height adjustment and precise positioning of the projection mechanism 2 through the ingenious design of the adjustment bracket 111. The bottom plate 1111 and the movable base 112 are rotatably matched to provide a stable base for the adjustment bracket 111; the folding group rod 1112 is hingedly matched with the bottom plate 1111, allowing the folding group rod 1112 to be unfolded upward or folded downward, thereby adjusting the vertical position of the projection mechanism 2; the top plate 1113 is hingedly connected to the folding group rod 1112 to connect the projection mechanism 2 to achieve its up and down movement adjustment. When working in linkage, the height of the projection mechanism 2 can be flexibly adjusted by controlling the unfolding or folding of the folding group rod 1112 to meet the projection requirements in different environments. This design not only improves the adaptability and convenience of the equipment, but also ensures the accurate transmission of projection information, providing great convenience for fault diagnosis and maintenance work;

[0073] Preferably, when downward projection to the ground is required, the projection surface of the projection mechanism 2 can be adjusted by unfolding or folding the folding rod 1112 to meet projection requirements at different heights. This design allows the user to dynamically adjust the vertical position of the projection mechanism 2 according to the actual projection environment, such as the height of the room or the specific position of the projection target, to ensure the clarity and accuracy of the projected image. The flexibility and adjustability of the folding rod 1112 improve the applicability and convenience of the projection system, so that it can play a good projection effect in various indoor occasions.

[0074] Further, see Figure 1 and 3 A connecting frame 12 is provided on the projection mechanism 2, and the connecting frame 12 is hingedly matched with the top plate 1113.

[0075] In this embodiment, the hinged connection between the connecting frame 12 and the top plate 1113 provides stable support and flexible adjustment capability, thereby ensuring stable projection and rapid deployment of the projection mechanism 2 at different positions.

[0076] Specifically, the technology provides a stable and flexible connection method by setting a connecting frame 12 on the projection mechanism 2 and making it hinged with the top plate 1113. The function of the connecting frame 12 is to serve as an intermediary structure. Its hinged cooperation with the top plate 1113 allows the projection mechanism 2 to be rotated and positioned at multiple angles within a certain range, so as to accurately align with the wall 100 or curtain to be projected. After the adjustment bracket 111 completes the vertical position adjustment of the projection mechanism 2, the connecting frame 12 further ensures the horizontal stability and flexibility of the direction adjustment of the projection mechanism 2. After linkage, the entire system can perform precise projection positioning according to the specific position and angle requirements of the projection surface, ensure the accuracy and clarity of the projection effect, and provide intuitive and accurate fault location information for maintenance personnel.
