Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets, and more particularly to an electrical control cabinet for intelligent electrical equipment and a protective structure thereof. Background Art

[0002] Electrical cabinets, also commonly referred to as distribution cabinets or switchgear, are key devices for power distribution, circuit control, and electrical equipment protection, ensuring the stable and safe operation of power systems. Over extended periods of operation, the various electrical components within these cabinets are subject to potential faults such as short circuits, overloads, fires, and loose contacts. These issues not only impact the normal operation of the power system but can even lead to serious safety incidents. To promptly identify and address these potential safety hazards, personnel must regularly conduct comprehensive inspections of the electrical cabinets. This traditional inspection method consumes significant time and effort, resulting in low efficiency and making real-time monitoring and timely response difficult.

[0003] Some existing solutions have proposed installing cameras inside electrical cabinets to achieve remote monitoring. For example, a Chinese patent application (Application No. 202220613330.8) discloses a highly intelligent electrical cabinet for electrical automation projects that utilizes this technology. By combining a drive component with a lead screw, the patent enables multi-dimensional movement of the camera within the distribution cabinet, providing a comprehensive view of the cabinet's conditions. This design undoubtedly improves the efficiency and accuracy of inspections, allowing personnel to promptly identify problems within the cabinet.

[0004] While this mobile camera system performs inspections, it has certain limitations. When workers discover problems within an electrical cabinet through remote camera inspections, they still need to physically visit the cabinet to perform repairs. This means that while the inspection process is remote, the repair process still relies on manual on-site operation, failing to achieve integrated inspection and repair capabilities. This single function makes the technology quite limited in its ability to address complex and diverse electrical cabinet failures. Summary of the Invention

[0005] In response to the problems existing in the above-mentioned technology, the purpose of the present invention is to propose an electrical control cabinet for intelligent electrical equipment and its protective structure, which can realize the installation of each electrical component into the corresponding installation slot, and monitor the electrical components in each installation slot through sensors. When a fire is found in an electrical component in any installation slot, the electrical cabinet performs self-diagnosis and performs a separate fire extinguishing operation on the installation slot that has caught fire. Since the installation slots are isolated from each other, the fire in one installation slot will not easily spread to the adjacent installation slots. This isolation design greatly reduces the risk of fire spreading inside the electrical equipment, avoids the fire from one electrical component to the adjacent electrical components, thereby protecting the safety of the entire electrical equipment and reducing equipment damage caused by fire.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] According to a first aspect of an embodiment of the present disclosure, a protective structure for an electrical control cabinet of intelligent electrical equipment is provided, comprising a cabinet body, a movement control assembly mounted inside the cabinet body, a camera mount mounted on the movement control assembly, and a camera mounted on the camera mount, wherein the movement control assembly is used to control the movement of the camera along the X-axis and the Y-axis.

[0008] A mounting rack is further installed inside the cabinet, and a plurality of mounting slots are provided on the mounting rack. The mounting slots are used to install electrical components. Wiring holes are provided on the side walls of the mounting slots. The electrical components in the mounting slots are electrically connected by passing the wiring through the wiring holes. After the wiring of the electrical components is arranged, the wiring holes are blocked. A smoke sensor is fixedly installed on the inner wall of the upper end of the mounting slot. A temperature sensor is installed on the inner wall of the mounting slot near the installation position of the electrical components. The temperature sensor is used to detect the temperature of the electrical components in the mounting slot.

[0009] The camera mount is provided with a plurality of groups of air duct holes, fans are installed inside the air duct holes, a bellows is installed at an edge position of a side of the camera mount, the end of the bellows away from the camera mount is fixedly connected to a fixing frame, a regulating component is installed inside the camera mount, the regulating component includes an electromagnet, which drives the fixing frame to fit the opening of the mounting slot by energizing the electromagnet, and controls the fan in the air duct hole to absorb air in the mounting slot; drives the fixing frame away from the opening of the mounting slot by energizing the electromagnet, and controls the fan in the air duct hole to blow air into the mounting slot.

[0010] Furthermore, a temperature threshold for the electrical components in each mounting slot is pre-set. If the temperature sensor detects that the temperature of the electrical components in the mounting slot reaches the preset temperature, the movement control component controls the camera mount to move to the corresponding mounting slot opening, and the control component controls the fan in the air duct hole to blow air into the mounting slot.

[0011] If the smoke sensor and temperature sensor in the installation slot reach the warning signal at the same time, it is the priority. The camera frame is controlled to move the smoke sensor and temperature sensor to the opening of the warning installation slot at the same time, and the fixed frame is driven to fit the opening of the installation slot by energizing the electromagnet. At the same time, the fan in the air duct hole is controlled to absorb air in the installation slot.

[0013] If the warning timestamps of the smoke sensor and temperature sensor in the installation slot are the same, the difference between the temperature detected by the temperature sensor and the preset threshold temperature of the appliance is calculated. The size of the difference is prioritized, and the camera mount is controlled to move to the installation slot opening corresponding to the largest difference. The fixing frame is controlled to fit the opening of the installation slot, and the fan is controlled to draw air into the installation slot.

[0014] Furthermore, if the temperature detected by multiple groups of temperature sensors reaches the preset temperature and the smoke sensor does not alarm, the difference between the temperature detected by the temperature sensor and the preset threshold temperature of the appliance is calculated, and the size of the difference is prioritized. The camera mount is controlled to move to the opening of the installation slot where the difference is the largest and corresponds to the difference, and the fan is controlled to blow air into the installation slot.

[0015] Furthermore, when the electrical components in the installation slot are working, the corresponding temperature values ​​at each moment are recorded, and the heating efficiency of the electrical components at the current moment is calculated in real time based on the temperature values ​​corresponding to the electrical components at each moment. The temperature of the electrical components at the next moment is estimated by the heating efficiency at the current moment, and the difference between the temperature of the electrical components at the next moment and the threshold is calculated. If the difference is a negative number, no judgment is made; if the difference is a positive number, the size of the difference is used as a priority, and the camera mount is preferentially controlled to move to the opening of the installation slot where the difference is the largest and corresponds to the difference, and the fan is controlled to blow air into the installation slot.

[0016] Furthermore, the regulating component includes a fixed block, which is fixedly mounted on the inner wall of the fixed frame. One side of the fixed block is fixedly connected to a telescopic column. The end of the telescopic column away from the fixed block is movably inserted into the interior of the camera frame and fixedly connected to a permanent magnet plate. An electromagnet is provided on one side of the permanent magnet plate away from the telescopic column.

[0017] Furthermore, the control component also includes gears, which are arranged in multiple groups and installed in the camera frame. One side of the gear is meshed with a rack, and the side of the rack away from the gear is fixedly connected to a connecting rod, and the end of the connecting rod away from the rack is fixedly connected to the permanent magnet plate. The center position of the lower surface of the gear is fixedly connected to a connecting column, and a fan rack is installed on the fan, and the upper and lower groups of the fan rack are fixedly connected by a connecting column.

[0018] Furthermore, the regulating component further comprises an elastic member, one end of the elastic member is fixedly connected to the permanent magnetic plate, and one end of the elastic member away from the permanent magnetic plate is fixedly connected to the inner wall of the camera frame.

[0019] Furthermore, the movement control component includes a first screw rod, which is installed inside the cabinet, and a moving block is provided on the first screw rod with a threaded transmission. A first driving motor is installed on the outside of the cabinet, and the first driving motor is used to drive the first screw rod to rotate forward and reverse. A second driving motor is installed on the outer surface of one side of the moving block, and a second screw rod is installed on the output shaft end of the second driving motor. The second screw rod is rotatably connected to a slider at one end away from the second driving motor, and an optical axis is installed at one end of the interior of the cabinet away from the first screw rod, and the slider is slidably sleeved on the optical axis, and the camera frame is threadedly provided on the second screw rod, and a sliding rod is also provided inside the camera frame, and both ends of the sliding rod movably pass through the camera frame, one end of which is fixedly connected to the moving block, and the other end is fixedly connected to the slider.

[0020] According to a second aspect of an embodiment of the present disclosure, an electrical control cabinet for intelligent electrical equipment is provided, wherein cabinet doors are installed at both the front and rear ends of the cabinet body, heat dissipation holes are opened on the left and right sides of the side walls of the cabinet body, and a cooling fan is installed inside the cabinet body near the heat dissipation holes.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This solution installs each electrical component in the corresponding installation slot and monitors the electrical components in each installation slot through sensors. When a fire occurs in an electrical component in any installation slot, the electrical cabinet performs self-diagnosis and performs a separate fire extinguishing operation on the installation slot that has caught fire. Since the installation slots are isolated from each other, a fire in one installation slot will not easily spread to an adjacent installation slot. This isolation design greatly reduces the risk of fire spreading inside the electrical equipment and avoids the fire spreading from one electrical component to an adjacent electrical component, thereby protecting the safety of the entire electrical equipment and reducing equipment damage caused by fire.

[0023] (2) The system of this solution can accurately locate the installation slot where the fault occurs based on the early warning signals of the smoke sensor and temperature sensor. At the same time, through the movement of the camera frame and the blowing or suction function of the wind, the system can carry out targeted treatment for specific problems. When the electrical component is overheated, the system will give priority to blowing air into the installation slot to cool it down; when the electrical component is smoking, the system will give priority to absorbing the smoke in the installation slot to prevent the spread of fire. This precise positioning and targeted treatment method greatly improves the efficiency and accuracy of fault handling.

[0024] (3) This solution also has the function of estimating the temperature of electrical components in advance. The system can record the temperature value of the electrical components at each moment and calculate the heating efficiency of the electrical components in real time based on these temperature values. Based on the heating efficiency at the current moment, the system can estimate the temperature of the electrical components at the next moment and compare it with the preset threshold. If the estimated temperature exceeds the threshold, the system will take cooling measures in advance, effectively preventing overheating damage and fire of the electrical components.

[0036] The cabinet 1 is further provided with a mounting frame 2, which is provided with a plurality of mounting slots 32. The mounting slots 32 are used to mount electrical components. Wiring holes 5 are provided on the side walls of the mounting slots 32. The electrical components in the mounting slots 32 are electrically connected by wiring through the wiring holes 5. After the wiring of the electrical components is arranged, the wiring holes 5 are sealed. A smoke sensor 4 is fixedly mounted on the inner wall of the upper end of the mounting slot 32. A temperature sensor 3 is installed on the inner wall of the mounting slot 32 near the mounting position of the electrical components. The temperature sensor 3 is used to detect the temperature of the electrical components in the mounting slot 32.

[0037] The camera frame 11 is provided with a plurality of air duct holes 15, and fans 16 are installed inside the air duct holes 15. A bellows 17 is installed at an edge of the camera frame 11 on a side where the camera 14 is installed. The end of the bellows 17 away from the camera frame 11 is fixedly connected to a fixing frame 18. A control component is installed inside the camera frame 11, and the control component includes an electromagnet 22. When the electromagnet 22 is energized, the fixing frame 18 is driven to fit the opening of the mounting slot 32, and at the same time, the fan 16 in the air duct hole 15 is controlled to absorb air in the mounting slot 32; when the electromagnet 22 is energized, the fixing frame 18 is driven away from the opening of the mounting slot 32, and at the same time, the fan 16 in the air duct hole 15 is controlled to blow air into the mounting slot 32.

[0038] The regulating assembly includes a fixed block 19, which is fixedly mounted on the inner wall of the fixed frame 18. A telescopic column 20 is fixedly connected to one side of the fixed block 19. The end of the telescopic column 20 away from the fixed block 19 is movably inserted into the interior of the camera frame 11 and is fixedly connected to a permanent magnet plate 21. An electromagnet 22 is provided on the side of the permanent magnet plate 21 away from the telescopic column 20. The regulating assembly also includes a gear 26, which is provided in multiple groups and is installed in the camera frame 11. One side of the gear 26 is meshed with a rack 25. The rack 25 A connecting rod 24 is fixedly connected to the side away from the gear 26, and the end of the connecting rod 24 away from the rack 25 is fixedly connected to the permanent magnet plate 21. A connecting column 28 is fixedly connected to the center position of the lower surface of the gear 26. A fan frame 27 is installed on the fan 16, and the upper and lower groups of the fan frame 27 are fixedly connected by the connecting column 28; the regulating assembly also includes an elastic member 23, one end of the elastic member 23 is fixedly connected to the permanent magnet plate 21, and the end of the elastic member 23 away from the permanent magnet plate 21 is fixedly connected to the inner wall of the camera frame 11;

[0039] A temperature threshold of the electrical components in each mounting slot 32 is set in advance. If the temperature sensor 3 detects that the temperature of the electrical components in the mounting slot 32 reaches the preset temperature, the movement control component controls the camera mount 11 to move to the opening of the corresponding mounting slot 32, and the control component controls the fan 16 in the air duct hole 15 to blow air into the mounting slot 32.

[0040] It should be noted that when electrical components are installed in the cabinet 1, each electrical component or separate module can be installed in a separate installation slot 32, and the wires between the electrical components can be connected to each other by passing the wires through the wiring holes 5. After the lines are installed, the wiring holes 5 are sealed with plasticine or other sealing materials. A wireless sending module and a wireless receiving module are also installed in the cabinet 1, which can be wirelessly interconnected with an external mobile terminal through the wireless sending module and the wireless receiving module. In this way, when the staff needs to check the electrical cabinet regularly, the first drive motor 6 is operated by remote control, and the first drive motor 6 controls the forward and reverse rotation of the first screw rod 7, thereby controlling the moving block 8 to move up and down, so that the camera frame 11 can be moved up and down. By controlling the forward and reverse rotation of the second drive motor 9, the forward and reverse rotation of the second screw rod 10 can be controlled. When the second screw rod 10 rotates forward and reverse, the camera frame 11 can be controlled to move left and right. By controlling the up, down, left and right movement of the camera frame 11, the camera 14 is moved to the opening in each installation slot 32, and the video or picture taken by the camera 14 is remotely transmitted to the staff's moving end point in real time. The staff can observe each electrical component remotely and realize remote rough maintenance.

[0041] When the temperature detected by the temperature sensor 3 in one group of mounting slots 32 reaches the preset temperature threshold, and the smoke sensor 4 does not detect a smoke signal, it means that the temperature of the electrical component in the mounting slot 32 is too high, and no fire has occurred. The electrical component cannot be cooled by general heat dissipation in the cabinet 1. At this time, the system will control the camera mount 11 to move to the opening of the mounting slot 32, control the fan 16 to be energized, and blow into the mounting slot 32 to achieve forced cooling of the high-temperature electrical component. The forced cooling time can be set. If the cooling of the electrical component is still not effective after the forced cooling time ends, for example, the temperature does not drop, or the temperature continues to rise, an alarm operation can be triggered, such as wirelessly sending an alarm message to the staff's mobile terminal, and at the same time triggering the circuit breaker in the cabinet 1 to cut off the power to the electrical components of the cabinet 1 to avoid the situation from getting serious.

[0042] In some embodiments of the present invention, if the smoke sensor 4 and the temperature sensor 3 in the mounting slot 32 reach the warning signal at the same time, it is a priority, and the camera frame 11 is preferentially controlled to move the smoke sensor 4 and the temperature sensor 3 to the opening of the warning mounting slot 32 at the same time, and the fixed frame 18 is driven to fit the opening of the mounting slot 32 by energizing the electromagnet 22, and the fan 16 in the air duct hole 15 is controlled to absorb the air in the mounting slot 32.

[0043] By adopting the above technical solution, if the smoke sensor 4 in one of the mounting slots 32 detects a smoke signal and the temperature detected by the temperature sensor 3 reaches a preset temperature threshold, it indicates that a fire has occurred in the electrical components in that mounting slot 32. If only the smoke sensor 4 detects a smoke signal and the temperature detected by the temperature sensor 3 does not reach the preset temperature threshold, it indicates that the smoke has been introduced into that mounting slot from smoke in another mounting slot 32, and no action is taken at this time. When a fire is detected in the mounting slot 32, an alarm signal can be triggered, for example, by transmitting the alarm signal to a staff member's mobile terminal, and simultaneously triggering a circuit breaker in the cabinet 1 to cut off the power. The camera frame 11 is then controlled to move toward the opening of the mounting slot 32. The electromagnet 22 is energized to generate magnetism, and the magnetic repulsion force pushes the permanent magnet plate 21 away from the electromagnet 22. The permanent magnet plate 21 drives the telescopic column 20 and the fixed block 19 to move through. The movement of the fixed block 19 drives the fixed frame 18 to move, and the fixed frame 18 tightly fits the edge of the opening of the mounting slot 32, thereby covering the opening of the mounting slot 32. When the permanent magnet plate 21 moves, it will drive the rack 25 to move through the connecting rod 24. When the rack 25 moves, it will drive the gear 26 to move. When the gear 26 moves, it will drive the connecting column 28 to rotate. The fan frame 27 is driven to rotate through the connecting column 28, so that the fan 16 flips 180°. When the fan 16 is powered on, the fan 16 no longer blows air into the mounting groove 32, but extracts air from the mounting groove 32. In this way, a negative pressure is formed in the mounting groove 32. In the case of lack of oxygen, the flame in the mounting groove 32 will be quickly extinguished, and the spread of fire will be avoided in time. By setting up multiple installation slots 32, each installation slot 32 is equivalent to an independent fire protection unit. When a fire occurs in an electrical component in one of the installation slots 32, the fire in the installation slot 32 is extinguished. Since the installation slots 32 are isolated from each other, the fire in one installation slot 32 will not easily spread to the adjacent installation slots 32. This isolation design greatly reduces the risk of fire spreading inside the electrical equipment and avoids the fire spreading from one electrical component to adjacent electrical components, thereby protecting the safety of the entire electrical equipment and reducing equipment damage caused by fire.

[0044] In some embodiments of the present invention, if multiple groups of smoke sensors 4 and temperature sensors 3 in the installation slots 32 reach the warning state at the same time, the timestamp is given priority; the camera mount 11 is preferentially controlled to move to the opening of the installation slot 32 corresponding to the smoke sensor 4 and temperature sensor 3 with the earliest timestamp, the fixing frame 18 is controlled to fit the opening of the installation slot 32, and the fan 16 is controlled to absorb the air in the installation slot 32.

[0045] By adopting the above technical solution, it is indicated that a fire has occurred in multiple installation slots 32 in the cabinet 1. First, a point-breaking operation is performed, and then the fire inside each installation slot 32 is extinguished one by one according to the chronological order. The fire extinguishing time can be set. After the fire in this installation slot 32 is extinguished, the fire is immediately moved to the next group of installation slots 32 to perform the fire extinguishing operation, ensuring that the entire fire extinguishing process is carried out in an orderly manner.

[0046] In some embodiments of the present invention, if the warning timestamps of the smoke sensor 4 and the temperature sensor 3 in the mounting slot 32 are the same, the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the appliance is calculated, and the size of the difference is prioritized. The camera mount 11 is preferentially controlled to move to the opening of the mounting slot 32 where the difference is largest and corresponds to the difference, and the fixing frame 18 is controlled to fit the opening of the mounting slot 32. At the same time, the fan 16 is controlled to absorb the air in the mounting slot 32.

[0047] By adopting the above technical solution, when fires occur simultaneously, that is, the timestamps of the fires are the same, the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the appliance is calculated. Because the greater the degree to which the temperature exceeds the safety threshold, the higher the risk of a serious fire. At this time, the fires are extinguished one by one through the set fire extinguishing sequence.

[0048] In some embodiments of the present invention, if the temperature detected by multiple groups of temperature sensors 3 reaches a preset temperature and the smoke sensor 4 does not alarm, the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the appliance is calculated, and the size of the difference is prioritized. The camera mount 11 is preferentially controlled to move to the opening of the mounting slot 32 where the difference is the largest and the corresponding mounting slot 32 is opened, and the fan 16 is controlled to blow air into the mounting slot 32.

[0049] By adopting the above technical solution, the larger the calculated difference, the closer the electrical components in the installation slot 32 are to the maximum temperature they can withstand, and the higher the risk of burnout or even fire. Therefore, the higher the priority, the cooling order is established in sequence, and then the cooling is carried out one by one.

[0050] In some embodiments of the present invention, when the electrical components in the installation slot 32 are working, the corresponding temperature values ​​at each moment are recorded, and the heating efficiency of the electrical components at the current moment is calculated in real time based on the temperature values ​​corresponding to the electrical components at each moment. The temperature of the electrical components at the next moment is estimated by the heating efficiency at the current moment, and the difference between the temperature of the electrical components at the next moment and the threshold is calculated. If the difference is a negative number, no judgment is made; if the difference is a positive number, the size of the difference is prioritized, and the camera mount 11 is preferentially controlled to move to the opening of the installation slot 32 where the difference is the largest and the corresponding difference, and the fan 16 is controlled to blow air into the installation slot 32.

[0051] By adopting the above technical solution, select the current moment and the previous moment The temperature values ​​are recorded as and , and then according to the calculation formula of heating efficiency ,in is the time interval, based on the heating efficiency at the current moment , to estimate the temperature of the electrical components at the next moment t+1 , the estimation formula is , calculate the difference between the temperature of the electrical component at the next moment and the threshold, and sort these positive differences in order from large to small. The larger the difference, the higher the risk of overheating of the electrical component in the installation slot 32, and the higher the priority. In this way, the trend of abnormal temperature increase of the electrical component can be discovered in advance, and cooling measures can be taken before the temperature reaches the threshold, effectively preventing overheating damage and fire of the electrical component, and improving the safety and reliability of the equipment.

[0052] If a fire is detected in some installation slots 32 and no fire is detected in other installation slots 32, but the temperature of the electrical component is higher than the preset temperature, the priority of the fire is higher than the priority of the electrical component out of control.

[0053] In the south or in a basement, the humidity is high, and when the temperature is low at night, water droplets are likely to appear on the inner wall of the cabinet 1 and the installation slot 32. If the electrical components in the installation slot 32 do not evaporate the water vapor in the installation slot 32 through the heat generated by themselves when working, water droplets will appear on the inner wall. When the water droplets flow down with gravity, they will flow to the humidity sensor 31. The humidity sensor 31 is installed on the inner wall of the installation slot 32 near the lower end. The humidity sensor 31 contacts the water droplets, and the detected humidity threshold reaches the preset threshold. The camera mount 11 is controlled to move to the opening of the installation slot 32 to perform a blowing operation. Through the flow of air, the moisture in the installation slot 32 is quickly evaporated to prevent too many water droplets from gathering and flowing into the circuit of the electrical components, causing a short circuit fault.

[0054] like Figure 1 As shown, cabinet doors 29 are installed at the front and rear ends of the cabinet 1, and heat dissipation holes are opened on the left and right sides of the side walls of the cabinet 1 for natural heat dissipation inside the cabinet 1. A cooling fan is installed near the heat dissipation holes inside the cabinet 1. The cooling fan blows air to accelerate the flow of air, thereby accelerating the overall cooling of the cabinet 1, avoiding the overall temperature accumulation and increase, and achieving cooling protection.

[0055] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
