Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets, and more specifically, to an electrical control cabinet for intelligent electrical equipment and its protection structure. Background Art

[0002] An electrical cabinet, usually also called a power distribution cabinet or a switch cabinet, is a key device for power distribution, circuit control, and protection of electrical equipment, ensuring the stable and safe operation of the power system. During the long-term operation of various electrical appliances in the electrical cabinet, it is inevitable to have problems such as short circuits, overloads, fires, and loose contact points. These problems not only affect the normal operation of the power system but may even cause serious safety accidents. To detect and solve these potential safety hazards in a timely manner, workers need to regularly conduct a comprehensive inspection of the electrical cabinet. This traditional inspection method consumes a large amount of time and energy of the workers, resulting in low work efficiency and being difficult to achieve real-time monitoring and timely response.

[0003] In the prior art, some people have proposed a solution to install a camera in the electrical cabinet to achieve remote monitoring. For example, an intelligent electrical cabinet with a high degree of intelligence for electrical automation engineering disclosed in a Chinese patent (application number 202220613330.8) adopts this technology. This patent, through the design of a driving component cooperating with a lead screw, enables the camera to move in multiple dimensions inside the power distribution cabinet, thereby observing the situation inside the power distribution cabinet comprehensively. This design undoubtedly improves the efficiency and accuracy of the inspection, enabling workers to discover problems existing in the electrical cabinet in a timely manner.

[0004] Although this movable camera realizes the inspection function, it has certain limitations. When workers discover problems in the electrical cabinet through remote control of the camera for inspection, they still need to come to the electrical cabinet in person for maintenance. This means that although the inspection process is remote, the maintenance process still relies on on-site manual operation and cannot achieve the integration of inspection and maintenance. This single function makes this technology appear relatively limited in dealing with complex and changeable electrical cabinet failures. Summary of the Invention

[0005] Aiming at the problems existing in the above technologies, the purpose of the present invention is to provide an electrical control cabinet and its protection structure for intelligent electrical equipment, which can install each electrical component into the corresponding installation slot, monitor the electrical components in each installation slot through sensors, and when it is found that an electrical component in any installation slot catches fire, the electrical cabinet conducts self-diagnosis and performs a separate fire extinguishing operation on the installation slot where the fire occurs. Since the installation slots are isolated from each other, the fire in one installation slot will not easily spread to adjacent installation slots. This isolation design greatly reduces the risk of fire spreading inside the electrical equipment, avoids the spread of fire from one electrical component to adjacent electrical components, thus 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 the first aspect of the embodiments of the present disclosure, a protection structure for an electrical control cabinet of an intelligent electrical equipment is provided, including a cabinet body. A mobile control component is installed inside the cabinet body, and a camera frame is further installed on the mobile control component. A camera is installed on the camera frame, and the mobile control component is used to control the camera to move along the X-axis and Y-axis directions;

[0008] An installation frame is also installed inside the cabinet body. A plurality of groups of installation slots are provided on the installation frame. The installation slots are used to install electrical components. Wiring holes are provided on the side walls of the installation slots. The electrical components in the installation slots are electrically connected by wires passing through the wiring holes. After the wiring of the electrical components is completed, the wiring holes are blocked. A smoke sensor is fixedly installed on the upper inner wall of the installation slot, and a temperature sensor is installed at the installation position of the electrical component close to the inner wall of the installation slot. The temperature sensor is used to detect the temperature of the electrical component in the installation slot;

[0009] A plurality of groups of air duct holes are provided on the camera frame. Fans are installed inside the air duct holes. A corrugated pipe is installed at the edge position of the side of the camera frame where the camera is installed. The end of the corrugated pipe far from the camera frame is fixedly connected to a fixed frame. A regulation component is installed inside the camera frame. The regulation component includes an electromagnet. By energizing the electromagnet, the fixed frame is driven to fit the opening of the installation slot, and at the same time, the fans in the air duct holes are controlled to suck the air in the installation slot; by energizing the electromagnet, the fixed frame is driven to move away from the opening of the installation slot, and at the same time, the fans in the air duct holes are controlled to blow air into the installation slot.

[0010] Furthermore, a temperature threshold of the electrical component in each installation slot is set in advance. If the temperature sensor detects that the temperature of the electrical component in the installation slot reaches the preset temperature, the mobile control component controls the camera frame to move to the opening of the corresponding installation slot, and the regulation component controls the fans in the air duct holes to blow air into the installation slot;

[0011] When the smoke sensor and the temperature sensor in the installation slot reach the warning signal simultaneously, it is of the highest priority. The camera frame is preferentially controlled to move to the opening of the installation slot where the smoke sensor and the temperature sensor reach the warning simultaneously, and the fixed frame is driven by the energization of the electromagnet to fit the opening of the installation slot. At the same time, the fan in the air duct hole is controlled to suck the air in the installation slot.

[0012] Furthermore, if multiple groups of smoke sensors and temperature sensors in the installation slots reach the warning state simultaneously, the time stamp is of the highest priority. The camera frame is preferentially controlled to move to the opening of the installation slot corresponding to the smoke sensor and the temperature sensor with the earliest time stamp, the fixed frame is controlled to fit the opening of the installation slot, and at the same time, the fan is controlled to suck the air in the installation slot.

[0013] If the warning time stamps of the smoke sensor and the temperature sensor in the installation slot are the same, calculate the difference between the temperature detected by the temperature sensor and the preset threshold temperature of the electrical appliance. Taking the size of the difference as the priority, the camera frame is preferentially controlled to move to the installation slot opening with the largest difference and the corresponding one, the fixed frame is controlled to fit the opening of the installation slot, and at the same time, the fan is controlled to suck the air in the installation slot.

[0014] Furthermore, if the temperatures detected by multiple groups of temperature sensors reach the preset temperature and the smoke sensor does not alarm, calculate the difference between the temperature detected by the temperature sensor and the preset threshold temperature of the electrical appliance. Taking the size of the difference as the priority, the camera frame is preferentially controlled to move to the installation slot opening with the largest difference and the corresponding one, and the fan is controlled to blow air into the installation slot.

[0015] Furthermore, when the electrical components in the installation slot are working, record the temperature values corresponding to each moment. According to the temperature values corresponding to each moment of the electrical components, calculate the current heating efficiency of the electrical components in real time. Estimate the temperature of the electrical components at the next moment through the current heating efficiency, calculate the difference between the temperature of the electrical components at the next moment and the threshold. If the difference is negative, no judgment and processing are made; if the difference is positive, taking the size of the difference as the priority, the camera frame is preferentially controlled to move to the installation slot opening with the largest difference and the corresponding one, and the fan is controlled to blow air into the installation slot.

[0016] Furthermore, the regulation component includes a fixed block. The fixed block is fixedly installed on the inner wall of the fixed frame. One side of the fixed block is fixedly connected with 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 with a permanent magnet plate. An electromagnet is arranged on the side of the permanent magnet plate away from the telescopic column.

[0017] Furthermore, the regulation component further includes gears. A plurality of sets of gears are provided and installed in the camera frame. One side of each gear is meshed with a rack. One side of the rack away from the gear is fixedly connected to a connecting rod. One end of the connecting rod away from the rack is fixedly connected to a permanent magnet plate. A connecting column is fixedly connected to the center position of the lower surface of the gear. A fan frame is installed on the fan. The upper and lower groups of the fan frames are fixedly connected through the connecting column.

[0018] Furthermore, the regulation component further includes an elastic member. One end of the elastic member is fixedly connected to the permanent magnet plate, and the other end of the elastic member away from the permanent magnet plate is fixedly connected to the inner wall of the camera frame.

[0019] Furthermore, the movement control component includes a first lead screw installed inside the cabinet body. A moving block is threadedly driven on the first lead screw. A first driving motor is installed outside the cabinet body, and the first driving motor is used to drive the first lead screw to rotate forward and backward. A second driving motor is installed on one side outer surface of the moving block. A second lead screw is installed at the output shaft end of the second driving motor. One end of the second lead screw away from the second driving motor is rotatably connected to a slider. A light shaft is installed at one end of the cabinet body away from the first lead screw. The slider is slidably sleeved on the light shaft. The camera frame is threadedly driven on the second lead screw. A slide bar is further provided inside the camera frame. Both ends of the slide bar movably penetrate 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 the second aspect of the embodiments of the present disclosure, there is provided an electrical control cabinet for an intelligent electrical device. Doors are installed at both the front and rear ends of the cabinet body. Heat dissipation holes are opened on both the left and right sides of the side wall of the cabinet body. A heat dissipation fan is installed at a position inside the cabinet body close to the heat dissipation holes.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

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

[0023] (2) The system of this solution can accurately locate the installation slot where a fault occurs based on the warning signals from the smoke sensor and the temperature sensor. At the same time, through the movement of the camera mount and the blowing or suction function of the wind, the system can handle specific problems in a targeted manner. When the electrical component is overheated, the system preferentially blows air into the installation slot for cooling; when the electrical component smokes, the system preferentially sucks the smoke in the installation slot to prevent the spread of fire. This way of accurate positioning and targeted handling greatly improves the efficiency and accuracy of fault handling.

[0024] (3) This solution also has the function of predicting the temperature of electrical components in advance. The system can record the temperature values of electrical components at each moment and calculate the temperature rise efficiency of electrical components in real time based on these temperature values. Through the current temperature rise efficiency, the system can predict the temperature of electrical components at the next moment and compare it with the preset threshold. If the predicted temperature exceeds the threshold, the system will take cooling measures in advance, effectively preventing the overheating damage of electrical components and the occurrence of fires.

Both ends of the slide bar 33 movably penetrate through the camera mount 11, one end of which is fixedly connected to the moving block 8, and the other end is fixedly connected to the slide block 13;

[0036] An installation frame 2 is also installed inside the cabinet body 1. A plurality of installation grooves 32 are provided on the installation frame 2. Electrical components are installed in the installation grooves 32. Wiring holes 5 are provided on the side walls of the installation grooves 32. The electrical components in the installation grooves 32 are electrically connected through wires passing through the wiring holes 5. After the wiring of the electrical components is completed, the wiring holes 5 are blocked. A smoke sensor 4 is fixedly installed on the upper inner wall of the installation groove 32. A temperature sensor 3 is installed on the inner wall of the installation groove 32 near the installation position of the electrical components. The temperature sensor 3 is used to detect the temperature of the electrical components in the installation groove 32.

[0037] A plurality of air duct holes 15 are provided on the camera mounting frame 11. A fan 16 is installed inside the air duct holes 15. A bellows 17 is installed at the edge position of the side of the camera mounting frame 11 where the camera 14 is installed. One end of the bellows 17 away from the camera mounting frame 11 is fixedly connected to a fixed frame 18. A control component is installed inside the camera mounting frame 11. The control component includes an electromagnet 22. By energizing the electromagnet 22, the fixed frame 18 is driven to fit the opening of the installation groove 32, and at the same time, the fan 16 inside the air duct holes 15 is controlled to suck the air inside the installation groove 32. By energizing the electromagnet 22, the fixed frame 18 is driven away from the opening of the installation groove 32, and at the same time, the fan 16 inside the air duct holes 15 is controlled to blow air into the installation groove 32.

[0038] The control component includes a fixed block 19. The fixed block 19 is fixedly installed on the inner wall of the fixed frame 18. One side of the fixed block 19 is fixedly connected to a telescopic column 20. One end of the telescopic column 20 away from the fixed block 19 is movably inserted into the inside of the camera mounting frame 11 and fixedly connected to a permanent magnet plate 21. An electromagnet 22 is arranged on the surface of the permanent magnet plate 21 away from the telescopic column 20. The control component also includes a plurality of gears 26. The gears 26 are installed inside the camera mounting frame 11. One side of the gear 26 is meshed with a rack 25. One side of the rack 25 away from the gear 26 is fixedly connected to a connecting rod 24. One 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. The upper and lower groups of the fan frames 27 are fixedly connected through the connecting column 28. The control component also includes an elastic member 23. One end of the elastic member 23 is fixedly connected to the permanent magnet plate 21. The end of the elastic member 23 away from the permanent magnet plate 21 is fixedly connected to the inner wall of the camera mounting frame 11.

[0039] The temperature threshold of the electrical components in each installation groove 32 is set in advance. If the temperature sensor 3 detects that the temperature of the electrical components in the installation groove 32 reaches the preset temperature, the mobile control component controls the camera mounting frame 11 to move to the opening of the corresponding installation groove 32, and the control component controls the fan 16 inside the air duct holes 15 to blow air into the installation groove 32.

[0040] It should be noted that when the electrical components are installed in the installation cabinet 1, each electrical component or a separate module can be installed in a separate installation groove 32. The wire connections between the electrical components can be made by passing wires through the wire routing holes 5. After the wiring is completed, the wire routing holes 5 are blocked with putty or other blocking materials. A wireless transmission module and a wireless reception module are also installed in the cabinet 1. Through the wireless transmission module and the wireless reception module, wireless interconnection with an external mobile terminal can be achieved. In this way, when the staff needs to regularly check the electrical cabinet, by remotely controlling the first drive motor 6 to work, the first lead screw 7 is controlled to rotate forward and backward, thereby controlling the up and down movement of the moving block 8. In this way, the up and down movement of the camera frame 11 can be realized. By controlling the forward and backward rotation of the second drive motor 9, the forward and backward rotation of the second lead screw 10 can be controlled. When the second lead screw 10 rotates forward and backward, it can control the left and right movement of the camera frame 11. By controlling the up, down, left, and right movement of the camera frame 11, the camera 14 is moved to the opening of each installation groove 32, and the video or picture captured by the camera 14 is transmitted in real time remotely to the mobile terminal of the staff. The staff can observe each electrical component remotely to achieve remote and rough maintenance.

[0041] When the temperature detected by the temperature sensor 3 in one of the groups of installation grooves 32 reaches the preset temperature threshold and the smoke sensor 4 does not detect a smoke signal, it indicates that the temperature of the electrical component in this installation groove 32 is too high and there is no fire. In the cabinet 1, normal heat dissipation can no longer dissipate heat from this electrical component. At this time, the system will control the camera frame 11 to move to the opening of this installation groove 32, and control the fan 16 to be powered on to blow air into this installation groove 32 to achieve forced cooling of this high-temperature electrical component. The forced cooling time can be set. If after the forced cooling time ends, the temperature drop of the electrical component still cannot reach effective cooling, for example, the temperature does not drop or continues to rise, an alarm operation can be triggered. For example, wirelessly send an alarm message to the mobile terminal of the staff, and at the same time trigger the circuit breaker in the cabinet 1 to cut off the power supply of the electrical components in the cabinet 1 to avoid the situation from getting worse.

[0042] In some embodiments of the present invention, when the smoke sensor 4 and the temperature sensor 3 in the installation groove 32 simultaneously reach the warning signal, it is given priority. The camera frame 11 is preferentially controlled to move to the opening of the installation groove 32 where the smoke sensor 4 and the temperature sensor 3 simultaneously reach the warning, and the electromagnet 22 is energized to drive the fixed frame 18 to fit the opening of the installation groove 32, and at the same time, the fan 16 in the air duct hole 15 is controlled to suck the air in the installation groove 32.

[0043] By adopting the above technical solution, when the smoke sensor 4 in one group of mounting grooves 32 detects a smoke signal and the temperature detected by the temperature sensor 3 reaches the preset temperature threshold, it indicates that there is a fire in the electrical components in this mounting groove 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 means that the smoke is from other mounting grooves 32 and has spread to this place, and no operation is performed at this time. When a fire is detected in the mounting groove 32, an alarm signal can be triggered. For example, the alarm signal is transmitted to the mobile terminal of the staff, and at the same time, the circuit breaker in the cabinet body 1 is triggered to perform a power-off operation. Then, the camera frame 11 is controlled to move to the opening of the mounting groove 32. The electromagnet 22 is energized to generate magnetism, and the permanent magnet plate 21 is pushed away from the electromagnet 22 by magnetic repulsion. The permanent magnet plate 21 drives the telescopic column 20 and the fixed block 19 to move. The movement of the fixed block 19 drives the fixed frame 18 to move, and the fixed frame 18 tightly fits on the edge of the opening of the mounting groove 32, so as to cover the opening of the mounting groove 32. When the permanent magnet plate 21 moves, it drives the rack 25 to move through the connecting rod 24. When the rack 25 moves, it drives the gear 26 to move. When the gear 26 moves, it drives the connecting column 28 to rotate. The connecting column 28 drives the fan frame 27 to rotate, so that the fan 16 makes a 180° flip. When the fan 16 is energized, 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 fire in the mounting groove 32 will be quickly extinguished, and the spread of the fire is timely avoided. Through the arrangement of multiple mounting grooves 32, each mounting groove 32 is equivalent to an independent fire prevention unit. When a fire occurs in the electrical components in one mounting groove 32, the mounting groove 32 is extinguished. Since the mounting grooves 32 are isolated from each other, the fire in one mounting groove 32 will not easily spread to the adjacent mounting grooves 32. This isolation design greatly reduces the risk of fire spreading inside the electrical equipment, avoids the spread of the fire from one electrical component to adjacent electrical components, thus protecting the safety of the entire electrical equipment and reducing equipment damage caused by fire.

[0044] In some embodiments of the present invention, if the smoke sensors 4 and temperature sensors 3 in multiple groups of mounting grooves 32 reach the warning state at the same time, the time stamp is taken as the priority; the camera frame 11 is preferentially controlled to move to the opening of the mounting groove 32 corresponding to the smoke sensor 4 and temperature sensor 3 with the earliest time stamp, the fixed frame 18 is controlled to fit the opening of the mounting groove 32, and at the same time, the fan 16 is controlled to suck the air in the mounting groove 32.

[0045] By adopting the above technical solution, it is indicated that a fire has occurred in multiple installation slots 32 inside the cabinet body 1. First, a disconnection operation is performed, and then the interiors of each installation slot 32 are extinguished one by one according to the chronological order. The extinguishing duration can be set. After the extinguishing of this installation slot 32 is completed, immediately move to the next group of installation slots 32 for extinguishing operations to ensure the orderly progress of the entire extinguishing process.

[0046] In some embodiments of the present invention, if the warning timestamps of the smoke sensor 4 and the temperature sensor 3 in the installation slot 32 are the same, calculate the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the electrical appliance. Taking the magnitude of the difference as the priority, preferentially control the camera frame 11 to move to the location with the largest difference and corresponding to the opening of the installation slot 32, control the fixing frame 18 to fit the opening of the installation slot 32, and at the same time control the fan 16 to suck the air inside the installation slot 32.

[0047] By adopting the above technical solution, when simultaneous fires occur, that is, the timestamps of the fires are the same, at this time, calculate the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the electrical appliance. Since the greater the degree to which its temperature exceeds the safety threshold, the highest risk of a serious fire occurs. At this time, through the set extinguishing sequence, extinguishing is carried out one by one.

[0048] In some embodiments of the present invention, if the temperatures detected by multiple groups of temperature sensors 3 reach the preset temperature and the smoke sensor 4 does not alarm, calculate the difference between the temperature detected by the temperature sensor 3 and the preset threshold temperature of the electrical appliance. Taking the magnitude of the difference as the priority, preferentially control the camera frame 11 to move to the location with the largest difference and corresponding to the opening of the installation slot 32, and control the fan 16 to blow air into the installation slot 32.

[0049] By adopting the above technical solution, the larger the calculated difference, the closer the electrical components in this installation slot 32 are to the maximum temperature they can withstand, and the higher the risk of being burned out or even catching fire. Therefore, the higher the priority, the cooling order is established in sequence, and then 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, record the corresponding temperature values at each moment. According to the corresponding temperature values of the electrical components at each moment, calculate the current heating efficiency of the electrical components in real time. Estimate the temperature of the electrical components at the next moment through the current heating efficiency, calculate the difference between the temperature of the electrical components at the next moment and the threshold. If the difference is negative, no judgment and processing are made; if the difference is positive, taking the magnitude of the difference as the priority, preferentially control the camera frame 11 to move to the location with the largest difference and corresponding to the opening of the installation slot 32, and control the fan 16 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 respectively denoted as and , and then according to the calculation formula of the heating efficiency , where is the time interval, based on the heating efficiency at the current moment, to estimate the temperature of the electrical component at the next moment t + 1. The prediction formula is . Calculate the difference between the temperature of the electrical component at the next moment and the threshold value. Sort these positive differences in descending order. The larger the difference, the higher the overheating risk of the electrical component in the installation slot 32 and the higher the priority. This can detect the trend of abnormal temperature increase of the electrical component in advance and take cooling measures before the temperature reaches the threshold value, effectively preventing the overheating damage of the electrical component and the occurrence of fire, and improving the safety and reliability of the equipment.

[0052] If there is a fire detected in some installation slots 32 and no fire is detected in some 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 getting out of control.

[0053] In a southern region or a basement with high humidity, when the temperature is low at night, water droplets are likely to appear on the inner walls of the cabinet body 1 and the installation slots 32. If the electrical components in the installation slots 32 do not evaporate the water vapor in the installation slots 32 through the heat generated by themselves during operation, resulting in water droplets on the inner walls. When the water droplets flow downward due to gravity and reach the humidity sensor 31, the humidity sensor 31 is installed near the lower end of the inner wall of the installation slot 32. When the humidity sensor 31 comes into contact with the water droplets and the detected humidity threshold reaches the preset threshold, the camera frame 11 is controlled to move to the opening of the installation slot 32 for blowing operation. Through the flow of air, the moisture in the installation slot 32 is quickly evaporated, preventing the water droplets from converging too much and flowing into the circuit of the electrical component, thus avoiding short-circuit faults.

[0054] As Figure 1 shown, cabinet doors 29 are installed at both the front and rear ends of the cabinet body 1. Heat dissipation holes are provided on both the left and right sides of the side walls of the cabinet body 1 for natural heat dissipation inside the cabinet body 1. Heat dissipation fans are installed at positions inside the cabinet body 1 near the heat dissipation holes. By blowing air with the heat dissipation fans, the flow of air is accelerated, thereby accelerating the overall cooling inside the cabinet body 1, avoiding the accumulation and increase of the overall temperature, and achieving cooling protection.
