Technical Field
[0001] The invention relates to the technical field of overvoltage suppression cabinets, and in particular to an overvoltage suppression cabinet comprehensive protection device. Background Art
[0002] Overvoltage suppression cabinet is a device used to protect electrical equipment from overvoltage. By using large-capacity overvoltage suppression components, the overvoltage suppression cabinet can effectively smooth the rising front edge of overvoltage, suppress and filter voltage spikes, and withstand the super-large energy generated by overvoltage. By real-time monitoring and analyzing the frequency components of grid resonance, the overvoltage suppression cabinet can quickly eliminate resonance, store and record various technical parameters under fault conditions, and facilitate accident analysis. In addition, the overvoltage suppression cabinet also has remote communication and data protection functions, and can realize data long-distance communication and data transmission with the user's microcomputer monitoring system through standard communication protocols. It has many functions; However, in the actual working process, only the suppression element is used to protect the electrical equipment. When the voltage flowing through the electrical equipment exceeds the working limit of the suppression element, it will still cause damage to the electrical equipment, especially to the plug of the electrical equipment. The excessively high voltage will cause the heat near the plug to rise rapidly, thereby causing the plug to deform and the electrical socket connected to the plug to be damaged, which is extremely harmful. In addition, when the voltage is too large, the staff does not know whether the electrical equipment as a whole is damaged. When the electrical equipment is damaged, it will also affect nearby electrical equipment, resulting in great safety hazards during the maintenance process of the staff.

[0006] Preferably, an isolation protection assembly is installed in the fixed box, and the isolation protection assembly includes multiple intermediate plates, and the multiple intermediate plates and stabilizing cylinders are arranged in an staggered manner, and the lower side of each intermediate plate is rotatably connected to two threaded rods, and the outer sides of the two threaded rods are threadedly sleeved with a threaded cylinder, and the two threaded rods are transmission connected to adjacent rotating rods through a pulley assembly, and two fixing rods are fixedly connected to the outer side of the intermediate plate, and the two fixing rods pass through the intermediate plate, and both ends of the two fixing rods are fixedly connected to a third connecting plate, and multiple round rods are installed on the lower side of the intermediate plate, and the multiple round rods are divided into two groups, and the outer side of each round rod is rotatably connected to a sleeve, and a second connecting plate is fixedly connected between two adjacent sleeves, and the uppermost round rod in each group is fixedly connected to the third connecting plate, and the side wall of the threaded cylinder is fixedly connected to an insertion rod, and the insertion rod slides through the lowermost round rod in each group.
[0007] Preferably, two second rings are fixedly connected to the upper side of each of the intermediate plates.

Moreover, during the above working process, the threaded cylinder will also be driven to move downward. The threaded cylinder drives the round rod to move downward through the insertion rod, and then the folded round rod, sleeve and third connecting plate are unfolded as a whole, which can form an obstacle between the electrical equipment, isolate and protect the electrical equipment with excessive flowing voltage, and reduce the adverse impact on the normal electrical equipment next to it when this electrical equipment is damaged.

Specific implementation manner
[0014] Refer to Figures 1-13 , a comprehensive protection device for overvoltage suppression cabinet, including a cabinet body 1. The cabinet body 1 includes a plurality of fixed boxes 3, and the plurality of fixed boxes 3 are fixedly connected end to end. A sealing plate 2 is rotatably installed on the outer side of each fixed box 3, and an observation window is fixedly installed in the sealing plate 2. A suppression element 5 is fixedly installed in each fixed box 3, and an electric plug board 6 is fixedly installed on the front side of the suppression element 5. An automatic disconnection assembly is installed in each fixed box 3. The automatic disconnection assembly includes a plurality of moving frames 10 slidably installed in the fixed box 3. A sliding groove 7 is opened on the upper side of each fixed box 3, and a plurality of sliding plates 14 are slidably connected in the sliding groove 7. A first electric push rod 8 is fixedly connected to the outer side of each sliding plate 14. A plurality of card holes 11 are opened on the upper side of each fixed box 3. A fixing plate 15 is fixedly sleeved on the outer side of the first electric push rod 8. A bolt 16 is threadedly connected to the outer side of the fixing plate 15, and one end of the bolt 16 extends into the card hole 11. A stabilizing cylinder 4 is fixedly connected to the lower side of the first electric push rod 8. A second electric push rod 21 is fixedly connected to the outer side of the stabilizing cylinder 4. The output end of the second electric push rod 21 is fixedly connected to a sleeve plate 20. Two moving rods 9 are slidably connected to the outer side of the sleeve plate 20. The moving frame 10 and the moving rod 9 are fixedly connected. A plurality of first pressure sensors 19 are fixedly connected to the inner side wall of each moving frame 10. A rubber ring is fixedly connected to the lower side of the stabilizing cylinder 4; First, the first pressure sensor 19 can sense pressure signals, convert the sensed pressure into electrical signals, and then transmit the converted electrical signals to the control center (such as mobile phones, computers, etc.), so that the staff can perceive the corresponding changes. Secondly, a display screen is installed on the outer side of the cabinet body 1. The first electric push rod 8 and the second electric push rod 21 are both electrically connected to the display screen through wires. Moreover, the electrical signals generated by the first pressure sensor 19 can also be transmitted into the display screen. The display screen can display the obtained data to the staff. And the suppression element 5 is also electrically connected to the display screen through wires. Before the device works, the corresponding electrical equipment is placed in the fixed box 3. The electrical equipment is electrically connected to the electric socket board 6 through wires. When the electrical equipment works, under the action of the suppression element 5, it can effectively prevent damage to the electrical equipment caused by excessive voltage. And when the electrical equipment works, the display screen can display the voltage flowing through the electrical equipment in real time. When the voltage flowing through the electrical equipment is too large, the display screen can also remind the staff. The above are all prior arts and will not be elaborated further; Moreover, when the electrical equipment is electrically connected, first move the whole first electric push rod 8. The first electric push rod 8 drives the stable cylinder 4 to move until the stable cylinder 4 moves to the middle position above the electrical equipment. At this time, screw the bolt 16 into the card hole 11, thereby completing the adjustment and fixing operation of the overall position of the sliding plate 14 and the first electric push rod 8. Then start the second electric push rod 21. The second electric push rod 21 drives the moving rod 9 to move towards the electric socket board 6 through the sleeve plate 20. The moving rod 9 drives the moving frame 10 to move towards the electric socket board 6 until the moving frame 10 abuts against the electric socket board 6. Put the plug of the electrical equipment between the moving rod 9 and the moving frame 10 and insert the plug into the electric socket board 6. Then, start the first electric push rod 8. The first electric push rod 8 drives the stable cylinder 4 to move downward until the stable cylinder 4 abuts against the electrical equipment, thereby completing the simple positioning effect of the electrical equipment. Repeat the above operations to complete the installation operation of all electrical equipment; When the pressure flowing through the electrical equipment is too high and exceeds the working limit of the suppression component 5, at this time, the controller will automatically activate the second electric push rod 21. The second electric push rod 21 drives the moving rod 9 to move away from the electric plug board 6 through the sleeve plate 20. The moving rod 9 drives the moving frame 10 to move away from the electric plug board 6. The moving frame 10 abuts against the plug of the electrical equipment and drives the plug to move away from the electrical equipment, thereby causing the plug of the electrical equipment and the electric plug board 6 to form a physically disconnected connection, reducing the impact on other electrical equipment. During the above working process, the first pressure sensor 19 always abuts against the plug, that is, the first pressure sensor 19 always emits an electrical signal, and this electrical signal will not change. When the voltage flowing through the electrical equipment is too high, if the value of the electrical signal emitted by the first pressure sensor 19 changes, it means that the plug of the electrical equipment is likely to be deformed (the reason for the deformation is mainly that the voltage is too high, and electrical energy is converted into heat energy, thereby causing the plug part to be burned out), and corresponding treatment needs to be carried out in a timely and rapid manner.
[0015] A detection component is installed in the stabilizing cylinder 4. The detection component includes a rotating plate 24 and a plurality of second pressure sensors 28 fixedly installed on the outside of the rotating plate 24. A rotating shaft 25 is rotatably connected in the stabilizing cylinder 4. The rotating plate 24 is fixedly connected to the rotating shaft 25. A second gear 26 is fixedly connected to the outside of the rotating shaft 25. Two rotating rods 13 are rotatably connected to the upper side of the stabilizing cylinder 4. First gears 22 are fixedly connected to the outside of the two rotating rods 13. Two connecting rods 29 are fixedly connected to the outside of the sleeve plate 20. Rack bars 23 are fixedly connected to the ends of the two connecting rods 29. The rack bars 23 are meshed with the first gears 22. One end of one of the rotating rods 13 extends into the stabilizing cylinder 4, and a third gear 27 is fixedly connected to the end of this rotating rod 13 located inside the stabilizing cylinder 4. The third gear 27 is meshed with the second gear 26; First, the structure, function and principle of the second pressure sensor 28 are exactly the same as those of the first pressure sensor 19, and when the second pressure sensor 28 senses pressure, it can also transmit the sensed pressure to the display screen. Secondly, when the stabilizing cylinder 4 and the electrical device are against each other, there is a certain distance between the second pressure sensor 28 and the electrical device. When the voltage flowing through the electrical device is too large, that is, after the second electric push rod 21 is started, the second electric push rod 21 drives the sleeve plate 20 to move, and the sleeve plate 20 drives the rack 23 to move through the connecting rod 29, and the rack 23 drives the rotating rod 13 to rotate through the first gear 22, and the rotating rod 13 drives the second gear 26 and the third gear 27. The rotating shaft 25 rotates, and the rotating shaft 25 drives the rotating plate 24 to rotate. The rotating plate 24 drives the second pressure sensor 28 to rotate around the rotating shaft 25. When the second pressure sensor 28 rotates, if the electrical equipment is deformed due to excessive voltage flowing through it, especially when the upper side of the electrical equipment is deformed, the deformed outer shell of the electrical equipment will be against the second pressure sensor 28, thereby causing the second pressure sensor 28 to send a corresponding electrical signal. The second pressure sensor 28 transmits the generated electrical signal to the display screen, which can not only detect whether the upper surface of the electrical equipment has changed, but also alert the staff if the electrical equipment is deformed, thereby killing two birds with one stone.
[0016] An isolation protection assembly is installed in the fixed box 3, and the isolation protection assembly includes a plurality of intermediate plates 18. The plurality of intermediate plates 18 and the stabilizing cylinder 4 are arranged alternately. The lower side of each intermediate plate 18 is rotatably connected to two threaded rods 33, and the outer sides of the two threaded rods 33 are threadedly sleeved with threaded cylinders 34. The two threaded rods 33 are transmission-connected to the adjacent rotating rods 13 through a pulley assembly 32. Two fixed rods 31 are fixedly connected to the outer side of the intermediate plate 18. The two fixed rods 31 both penetrate the intermediate plate 18. Both ends of the two fixed rods 31 are fixedly connected to a third connecting plate 36. A plurality of round rods 37 are installed on the lower side of the intermediate plate 18. The plurality of round rods 37 are divided into Two groups, each group of round rods 37 is arranged up and down, each round rod 37 is rotatably connected to the outer side of the sleeve 38, a second connecting plate 35 is fixedly connected between two adjacent sleeves 38, the uppermost round rod 37 of each group is fixedly connected to the third connecting plate 36, the side wall of the threaded cylinder 34 is fixedly connected to the plug rod 39, the plug rod 39 slides through the lowermost round rod 37 in each group, the upper side of each intermediate plate 18 is fixedly connected to two second circular rings 30, the upper sides of the two second circular rings 30 are slidably sleeved with the first connecting plate 12, the outer side of each slide plate 14 is fixedly connected to two first circular rings 17, the first connecting plate 12 and the adjacent first circular rings 17 are slidably connected; First, the pulley assembly 32 includes two pulleys, a belt, and a tension pulley. One of the pulleys is fixedly connected to the threaded rod 33, and the other is slidably connected to the rotating rod 13 in the vertical direction. The tension pulley is slidably connected to the middle plate 18. Under the action of the tension pulley, the belt can always be in a normal transmission state. The above are all prior arts and will not be elaborated further. Secondly, during the process of adjusting the position of the sliding plate 14, under the action of the two first connecting plates 12, the middle plate 18 is always located in the middle position between two adjacent sliding plates 14 (here, the sliding plate 14 and the middle plate 18 can be approximately regarded as a triangle. Since the distance between the middle plate 18 and the sliding plate 14 is always fixed, that is, the triangle formed by the sliding plate 14 and the middle plate 18 is an isosceles triangle, so the middle plate 18 is always in the middle of the two sliding plates 14). When the voltage flowing through the electrical equipment is too high and the second electric push rod 21 is activated, the rotating rod 13 starts to rotate. The rotating rotating rod 13 will drive the threaded rod 33 to rotate through the pulley assembly 32. Since the multiple round rods 37, sleeves 38, and the third connecting plate 36 are of a folding structure, and under the action of the insertion rod 39, the threaded cylinder 34 can only move in the vertical direction and cannot rotate with the threaded rod 33. At this time, the rotating threaded rod 33 will drive the threaded cylinder 34 to move downward. The threaded cylinder 34 drives the round rod 37 to move downward through the insertion rod 39, thereby causing the overall expansion of the folded round rod 37, sleeve 38, and the third connecting plate 36, which can form an obstacle between the electrical equipment, isolate and protect the electrical equipment with too high flowing voltage, and reduce the adverse impact on the normal electrical equipment next to it when this electrical equipment is damaged. Moreover, in the initial state, the round rod 37, sleeve 38, and the third connecting plate 36 are in a folded state, and the whole of the round rod 37, sleeve 38, and the third connecting plate 36 is located above the electrical equipment and will not cause adverse effects on the electrical equipment.
[0017] In the present invention, before the device works, the corresponding electrical equipment is placed in the fixed box 3. The electrical equipment is electrically connected to the electric plug board 6 through a wire. When the electrical equipment is working, under the action of the suppression element 5, it can effectively prevent the voltage from being too high from damaging the electrical equipment. And when the electrical equipment is working, the display screen can display the voltage flowing through the electrical equipment in real time. When the voltage flowing through the electrical equipment is too high, the display screen can also remind the staff. The above are all prior arts and will not be elaborated further; When making an electrical connection for an electrical device, first move the entire first electric push rod 8. The first electric push rod 8 drives the stable cylinder 4 to move until the stable cylinder 4 moves to the middle position above the electrical device. At this time, screw the bolt 16 into the card hole 11, thereby completing the adjustment and fixing operations for the overall positions of the sliding plate 14 and the first electric push rod 8. Then, start the second electric push rod 21. The second electric push rod 21 drives the moving rod 9 to move towards the direction close to the electric plug board 6 through the sleeve plate 20. The moving rod 9 drives the moving frame 10 to move towards the direction close to the electric plug board 6 until the moving frame 10 abuts against the electric plug board 6. Put the plug of the electrical device between the moving rod 9 and the moving frame 10 and insert the plug into the electric plug board 6. Then, start the first electric push rod 8. The first electric push rod 8 drives the stable cylinder 4 to move downward until the stable cylinder 4 abuts against the electrical device, thereby completing a simple positioning effect for the electrical device. Repeat the above operations to complete the installation operations for all electrical devices; When the pressure flowing through the electrical device is too high and exceeds the working limit of the suppression element 5, at this time, the display screen will automatically start the second electric push rod 21. The second electric push rod 21 drives the moving rod 9 to move away from the electric plug board 6 through the sleeve plate 20. The moving rod 9 drives the moving frame 10 to move away from the electric plug board 6. The moving frame 10 abuts against the plug of the electrical device and drives the plug to move away from the electrical device, thereby causing a physical disconnection between the plug of the electrical device and the electric plug board 6, reducing the impact on other electrical devices. During the above working process, the first pressure sensor 19 always abuts against the plug, that is, the first pressure sensor 19 always emits an electric signal and this electric signal does not change. When the voltage flowing through the electrical device is too high, if the value of the electric signal emitted by the first pressure sensor 19 changes, it means that the plug of the electrical device is very likely to be deformed (the main reason for deformation is that the voltage is too high, electrical energy is converted into heat energy, and then the plug part is burned out), and corresponding processing needs to be carried out in a timely and rapid manner; When the stabilizing cylinder 4 abuts against the electrical equipment, there is a certain distance between the second pressure sensor 28 and the electrical equipment. When the voltage flowing through the electrical equipment is too high, that is, after the second electric push rod 21 is activated, when the second electric push rod 21 drives the sleeve plate 20 to move, the sleeve plate 20 drives the rack 23 to move through the connecting rod 29. The rack 23 drives the rotating rod 13 to rotate through the first gear 22. The rotating rod 13 drives the rotating shaft 25 to rotate through the second gear 26 and the third gear 27. The rotating shaft 25 drives the rotating plate 24 to rotate. The rotating plate 24 drives the second pressure sensor 28 to rotate around the rotating shaft 25. When the second pressure sensor 28 rotates, if the electrical equipment deforms due to the excessive voltage flowing through it, especially when the deformation occurs on the upper side of the electrical equipment, the deformed outer shell of the electrical equipment will abut against the second pressure sensor 28, resulting in the second pressure sensor 28 emitting a corresponding electrical signal. The second pressure sensor 28 transmits the generated electrical signal to the display screen, which can not only detect whether the upper surface of the electrical equipment has changed, but also remind the staff when the electrical equipment deforms, achieving multiple benefits with one move; During the process of adjusting the position of the slide plate 14, under the action of the two first connecting plates 12, the intermediate plate 18 has always been located in the middle position between two adjacent slide plates 14 (here, the slide plate 14 and the intermediate plate 18 can be approximately regarded as a triangle. Since the distance between the intermediate plate 18 and the slide plate 14 has always been fixed, that is, the triangle formed by the slide plate 14 and the intermediate plate 18 is an isosceles triangle, so the intermediate plate 18 has always been in the middle of the two slide plates 14). When the voltage flowing through the electrical equipment is too high and the second electric push rod 21 is activated, the rotating rod 13 starts to rotate. The rotating rotating rod 13 will drive the threaded rod 33 to rotate through the pulley assembly 32. Since the multiple round rods 37, sleeves 38 and the third connecting plate 36 are of a folding structure, and under the action of the inserting rod 39, the threaded cylinder 34 can only move in the vertical direction and cannot rotate with the threaded rod 33. At this time, the rotating threaded rod 33 will drive the threaded cylinder 34 to move downward. The threaded cylinder 34 drives the round rod 37 to move downward through the inserting rod 39, resulting in the overall unfolding of the folded round rod 37, sleeve 38 and the third connecting plate 36, which can form an obstacle between the electrical equipment, isolate and protect the electrical equipment with excessive flowing voltage, and reduce the adverse impact on the normal electrical equipment beside when this electrical equipment is damaged. Moreover, in the initial state, the round rod 37, sleeve 38 and the third connecting plate 36 are in a folded state, and the whole of the round rod 37, sleeve 38 and the third connecting plate 36 is located above the electrical equipment, without causing adverse effects on the electrical equipment.
