[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0034] like Figure 1 and Figure 2 As shown, an intelligent outdoor safety protection power distribution room includes a power distribution room body arranged outdoors, a lifting lightning rod 2 and an atmospheric electric field instrument 3 are arranged on the roof of the power distribution room body 1, a lightning rod 4 is arranged on the top of the lifting lightning rod 2, and a control box electrically connected to the lifting lightning rod 2 and the atmospheric electric field instrument 3 is arranged in the power distribution room body 1;
[0035] The lifting lightning rod 2 is rotatably installed on the roof of the power distribution room body 1. When the power distribution room body 1 needs to be protected from lightning, the lifting lightning rod 2 is rotated from a horizontal state to a vertical state by a telescopic rod 5. When the lifting lightning rod 2 is rotated to the vertical state, it is locked and fixed by a locking assembly;
[0036] The telescopic rod 5 is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod, the output end of the telescopic rod 5 is hinged to the lower part of the lifting lightning rod 2, and the bottom end of the outer tube of the telescopic rod 5 is hinged to the sliding device 6 that can slide back and forth along the roof of the power distribution room body 1; when the lifting lightning rod 2 is in a horizontal state, the sliding device 6 is close to the base 9 for installing the lifting lightning rod 2, and the hinge point of the telescopic rod 5 and the lifting lightning rod 2 and the hinge point of the telescopic rod 5 and the sliding device 6 can be located in the same horizontal plane, or the hinge point of the telescopic rod 5 and the lifting lightning rod 2 is higher than the hinge point of the telescopic rod 5 and the sliding device 6;
[0037] A support block 32 is provided on the roof of the power distribution room body 1 at a position corresponding to the upper part of the lifting lightning rod 2 when it is lying horizontally. When the lifting lightning rod 2 is lying horizontally, the support block 32 cooperates with the base 9 to keep the lifting lightning rod 2 horizontal, and the upper end of the support block 32 is a concave surface adapted to the outer surface of the lifting lightning rod 2; in order to facilitate the telescopic rod 5 to smoothly push the lifting lightning rod 2 in the lying state to the upright state, a vertical state pushing device is provided inside the support block 32, and the pushing device can be a cylinder or a hydraulic cylinder, the output end of the pushing device conflicts with the lifting lightning rod 2, and when the pushing device is in a non-working state, the output end of the pushing device is located in the support block 32, or the output end of the pushing device is flush with the concave surface of the support block 32, when the lifting lightning rod 2 is erected, the upper end of the lifting lightning rod 2 is first pushed to a certain height by the pushing device, and then the telescopic rod 5 continues to extend and drive it to a vertical state;
[0038] The bottom end of the lightning rod 4 is connected to a down conductor 7, and the other end of the down conductor 7 is connected to a grounding copper bar 8 installed on the side of the power distribution room body 1. The lower end of the grounding copper bar 8 is buried in the ground and is conductively connected to the buried copper bar.
[0039] The atmospheric electric field instrument 3 adopts a solar power generation power supply mode. The atmospheric electric field instrument 3 is used to monitor the electric field changes near the power distribution room body 1, and feed back the monitoring results to the control box in real time. The control box determines whether to issue an operation control instruction to the lifting lightning rod 2 and the telescopic rod 5 according to the received monitoring results;
[0040] The control box is also connected to a host computer via a wireless network or a wired network, and the control box receives remote control instructions from the host computer. In the non-thunderstorm season, the control box is in a sleep state. In the early stage of the thunderstorm season, the host computer sends a start-up instruction to the control box, and the control box changes from the sleep state to the standby state. The control box starts the atmospheric electric field meter 3, and the atmospheric electric field meter 3 monitors the electric field changes near the distribution room body 1 in real time.
[0041] like Figure 6 As shown, the locking assembly includes a mounting barrel 10 fixed on a base 9 for mounting the lifting lightning rod 2, a first spring 11 is arranged in the mounting barrel 10, one end of the first spring 11 abuts against the base 9, and the other end of the first spring 11 is fixedly connected with a slide plate 12, a side of the slide plate 12 facing away from the first spring 11 is provided with a permanent magnet 13, an inner bottom surface of the mounting barrel 10 is provided with an electromagnet 14 electrically connected to the control box, a side of the slide plate 12 facing the first spring 11 is provided with a plurality of plug rods 15, and a socket 16 matching the plug rod 15 is provided at the bottom of the base 9 and the lifting lightning rod 2;
[0042] Specifically, the number of the plug rods 15 is three, which are arranged on a circular contour with the center of the slide plate 12 as the center, and the number of the sockets 16 is also three. The sockets 16 on the lifting lightning rod 2 are arranged at a position corresponding to the plug rod 15 when the lifting lightning rod 2 is in a vertical state; in the non-working state, the electromagnet 14 is in a power-off state, and the permanent magnet 13 is in contact with the electromagnet 14 under the elastic force of the first spring 11. When the lifting lightning rod 2 rotates to a vertical state, the control box energizes the electromagnet 14. After the electromagnet 14 is energized, the electromagnetic polarity of the electromagnet 14 and the permanent magnet 13 at the opposite end is the same. In this way, under the action of like-charge repulsion, the permanent magnet 13 pushes the slide plate 12 to move to the left, and the slide plate 12 drives the plug rod 15 to move to the left. Finally, the plug rod 15 is inserted into the sockets on the base 9 and the lifting lightning rod 2 to limit and fix the lifting lightning rod 2 and improve the wind resistance of the lifting lightning rod 2.
[0043] like Figure 4 and Figure 7As shown, a slide groove 17 is provided on the power distribution room body 1 at a position corresponding to the installation of the lifting lightning rod 2, and the sliding device 6 is installed in the slide groove 17; the sliding device 6 includes an inverted U-shaped slider 601 and a slide rail 602 arranged in the slide groove 17, the inverted U-shaped slider 601 is slidably connected to the slide rail 602, a driving device 603 is provided on the side of the inverted U-shaped slider 601, and a gear 604 is installed on the output shaft of the driving device 603, and the gear 604 partially passes through the inverted U-shaped slider 601 and is engaged with the gear on the side of the slide rail 602 meshing with each other; the driving device 603 includes a motor and a speed changer, which are assembled and fixed on the side of the inverted U-shaped slider 601, with the output shaft of the speed changer facing downward, and the gear 604 is installed on the output shaft of the speed changer; in order to enable the inverted U-shaped slider 601 to slide smoothly from the right end to the left end of the slide groove 17, a driving device 603 is respectively arranged on the two side surfaces of the inverted U-shaped slider 601, and the motors of the two driving devices 603 run synchronously to drive the two gears 604 to rotate towards each other, so that they can roll back and forth along the teeth on the side of the slide rail 602.
[0044] like Figure 4 As shown, a roller 605 is provided on the lower side of the inverted U-shaped slider 601, and the roller 605 rolls on the surface connected to the slide groove 17, thereby effectively reducing the friction between the inverted U-shaped slider 601 and the ground of the slide groove 17, so that the inverted U-shaped slider 601 can move back and forth smoothly in the slide groove 17; a travel switch 18 is provided on the inner wall of the slide groove 17 away from the base 9, and the travel switch 18 is electrically connected to the control box. When the inverted U-shaped slider 601 moves to the position of the travel switch 18 and touches the inverted travel switch 18, the travel switch 18 feeds back a signal to the control box, and the control box sends a stop command to the motor of the drive device 603.
[0045] like Figure 4 As shown, a push-pull electromagnet 19 is installed at one end of the slide rail 602 away from the base 9, and the moving iron core of the push-pull electromagnet 19 can extend out of the upper side of the slide rail 602, and the inverted U-shaped slider 601 is provided with a countersunk hole adapted to the moving iron core; the push-pull electromagnet 19 is electrically connected to the control box. When the control box receives the triggered signal fed back by the travel switch 18, the control box sends a command to the push-pull electromagnet 19, and the moving iron core of the push-pull electromagnet 19 protrudes from the upper side of the slide rail 602 and is inserted into the countersunk hole on the inverted U-shaped slider 601, thereby fixing the inverted U-shaped slider 601. When the telescopic rod 5 is placed to continue to push the lifting lightning rod 2, the gravity separation of the lifting lightning rod 2 in the inclined state generates a reaction force on the inverted U-shaped slider 601, causing the inverted U-shaped slider 601 to move to the left.
[0046] like Figure 1 , Figure 2 and Figure 8 As shown, the grounding copper bar 8 is installed in a shell 20, and the inner side wall of the shell 20 is provided with an insulating layer 21 covering the grounding copper bar 8. The insulating layer 21 effectively insulates and isolates the grounding copper bar 8 from the shell 20, avoiding the risk of leakage between the grounding copper bar 8 and the shell 20 when the grounding copper bar 8 transmits the lightning current received by the lightning rod 4 to the earth; the shell 20 is clamped on the side of the power distribution room body 1 by a clamping component pre-buried in the power distribution room body 1, and the clamping component facilitates the shell 20 to be quickly installed on the side of the power distribution room body 1 when the grounding copper bar 8 is installed on site.
[0047] like Figure 8 As shown, the clamping assembly includes an upper clamping block 22 and a lower clamping block 23, the lower side surface of the upper clamping block 22 is provided with an inner sleeve 24, the upper side surface of the lower clamping block 23 is provided with an outer sleeve 25 sleeved on the outer side surface of the inner sleeve 24, the outer side surface of the lower end of the inner sleeve 24 is provided with an outer annular block, the inner side surface of the upper end of the outer sleeve 25 is provided with an inner annular block, the inner annular block is located on the upper side surface of the outer annular block, so as to play a role of longitudinal limiting between the inner sleeve 24 and the outer sleeve 25; a second spring 26 located in the inner sleeve 24 and the outer sleeve 25 is provided between the upper clamping block 22 and the lower clamping block 23, and a clamping groove 27 adapted to the upper clamping block 22 and the lower clamping block 23 is provided on the outer side surface of the casing 20;
[0048] Specifically, at the position on the power distribution room body 1 for installing the casing 20, a plurality of installation grooves are provided along the vertical direction of the side surface of the power distribution room body 1, and the slot 27 forms a horizontal T-shaped structure with the cross section of the installation groove. Under the elastic force of the second spring 26, when the outer annular block of the inner sleeve 24 and the inner annular block of the outer sleeve 25 contact each other, the upper clamping block 22 and the lower clamping block 23 are completely in contact with the upper side wall or the lower side wall of the installation groove; the upper clamping block 22 and the lower clamping block 23 are symmetrical structures with the same structure, the upper clamping block 22 is a U-shaped structure, and the lower clamping block 23 is an inverted U-shaped structure, and the ends of the left vertical plates of the upper clamping block 22 and the lower clamping block 23 are both set as inclined surfaces, and when the upper clamping block 22 and the lower clamping block 23 respectively contact the upper and lower side walls of the installation groove, the inclined surface and the upper clamping block 22 or the lower clamping block 23 The intersection of the left side surface of the upper and lower side walls of the opening of the side surface of the casing 20 corresponding to the slot 27 are located in the same plane, so when installing the casing 20, it is only necessary to correspond the opening of the slot 27 to the intersection of the inclined surface and the vertical surface of the upper clamping block 22 and the lower clamping block 23, and then press the casing 20 toward the side of the power distribution room body 1 to push the upper clamping block 22 and the lower clamping block 23 to move relative to each other. When the left ends of the upper clamping block 22 and the lower clamping block 23 are inserted into the slot 27, since the left space of the slot 27 is larger than the space at the opening, the upper clamping block 22 and the lower clamping block 23 can be smoothly inserted into the slot 27 under the action of the second spring 26; the left vertical plate of the upper clamping block 22 and the lower clamping block 23 is shorter than the right vertical plate, so that when the upper clamping block 22 and the lower clamping block 23 move relative to each other to the limit distance, the upper clamping block 22 and the lower clamping block 23 will not fall out of the installation groove.
[0049] like Figure 2 , Figure 4 and Figure 5 As shown, the down conductor 7 is connected to the grounding copper bar 8 through an elastic top tightening member; the elastic top tightening member includes a T-shaped block 28 installed on the lower side of the eaves of the power distribution room body 1, the T-shaped block 28 is made of hard insulating material, the lower side of the T-shaped block 28 is provided with a first electrode 29 connected to the down conductor 7, the upper end of the grounding copper bar 8 is provided with a slot, the slot is provided with a second electrode 30 connected to the grounding copper bar 8, the upper side of the T-shaped block 28 is provided with a third spring 31, the third spring 31 drives the T-shaped block 28 so that the first electrode 29 abuts against the second electrode 30;
[0050] Specifically, a T-shaped mounting groove is also provided on the lower side of the eaves of the distribution room body 1 for installing the lifting lightning rod 2, and the T-block 28 is arranged in the mounting groove. One end of the third spring 31 abuts against the upper side wall of the mounting groove, and the other end of the third spring 31 abuts against the upper side of the T-block 28. Under the elastic force of the third spring 31, the lower end of the T-block 28 protrudes from the lower side of the eaves, and the first electrode 29 is inserted into the slot and abuts against the second electrode 30, so that the down conductor 7 is conductive with the grounding copper bus 8.
[0051] The distribution cabinets, control boxes, switch cabinets, etc. in the distribution room body 1 provided by the present invention are all equipped with lightning arresters, and the lightning arresters are respectively connected to the grounding copper bus 8 on the side of the distribution room body 1 through the down conductor 7 to provide lightning protection for the distribution cabinets and other equipment in the distribution room body 1; the base 9 is two vertical plates fixed in parallel on the eaves of the distribution room body 1, and a travel switch 18 is also arranged between the two vertical plates, and a trigger rod is arranged at the bottom of the lifting lightning rod 2, and when the lifting lightning rod 2 is rotated to a vertical state, the trigger rod can touch the travel switch 18.
[0052] The lightning protection working process of the intelligent outdoor safety protection distribution room provided by the present invention is as follows:
[0053] Lightning protection preparation stage:
[0054] The control box is in a sleeping state in spring, autumn and winter. When entering summer, the upper computer sends a standby command to the control box. After the control box is started, it is in a standby state. In this standby state, the control box first sends an operation command to the atmospheric electric field instrument 3, and the atmospheric electric field instrument 3 feeds back the detection results to the control box in real time. When the atmospheric electric field strength received by the control box exceeds the preset atmospheric electric field strength, the control box sends an operation command to the telescopic rod 5 and the motor of the driving device 603;
[0055] At this stage, due to the difference in climate between the north and south of my country in summer, thunderstorms in the north are periodic, while thunderstorms in the south are more frequent; therefore, in the summer in the north, the host computer can send a standby command to the control box only when it determines that there will be thunderstorms the next day based on the weather forecast information issued by the Meteorological Bureau. When the weather forecast information shows that the area is sunny, the control box can still remain in the sleep state; while in the south, the host computer will send a standby command to the control box when summer arrives;
[0056] In addition, the thunderstorm season in some areas arrives earlier and ends later than in other areas. Therefore, the cycle for the host computer to send standby instructions to the control box can be set according to the characteristics of the area.
[0057] Stages of lightning protection:
[0058] First, the control box sends an operation command to the motors of the pushing device and the driving device 603. The pushing device pushes the upper end of the lifting lightning rod 2 to a certain height. At the same time, the motor drives the gear 604 to rotate to drive the inverted U-shaped slider 601 to move to the left along the slide rail 602 synchronously. When the pushing device stops running, the motor continues to run to drive the inverted U-shaped slider 601 to move to the left.
[0059] Next, when the inverted U-shaped slider 601 moves to make the telescopic rod 5 in a vertical state, the control box sends a start command to the telescopic rod 5, and the telescopic rod 5 runs to extend (the time of issuing the command can be calculated and determined according to the running speed of the motor and the distance when the inverted U-shaped slider 601 moves from the rightmost end to the telescopic rod in a vertical state), so that the inverted U-shaped slider 601 moves to the left and the telescopic rod 5 extends;
[0060] Next, when the inverted U-shaped slider 601 moves to the leftmost end and touches the inverted travel switch 18, the travel switch 18 feeds back a signal to the control box. After receiving the feedback signal from the travel switch 18, the control box sends a stop command to the motor and simultaneously sends a start command to the push-pull electromagnet 19. The moving iron core of the push-pull electromagnet 19 is inserted into the countersunk hole on the lower side of the inverted U-shaped slider 601.
[0061] The telescopic rod 5 continues to extend, and the lifting lightning rod 2 is rotated to Figure 3 In the vertical state shown, the trigger rod at the bottom of the lifting lightning rod 2 touches the travel switch 18 at the base 9, and the travel switch 18 feeds back a signal to the control box. After receiving the feedback signal from the travel switch 18, the control box sends a stop operation command to the telescopic rod 5; when the lifting lightning rod 2 is in the vertical state, the control box can send an operation command to the electric drive device of the lifting lightning rod 2 to drive the lifting lightning rod 2 to extend and raise the lightning rod 4 to a required height (the specific height can be set according to specific actual needs, and whether the lightning rod 4 reaches the preset height is determined by the number of turns of the stepper motor of the drive device of the lifting lightning rod 2);
[0062] Then, the control box synchronously sends an operation command to the electromagnet 14. After the electromagnet 14 is energized, the opposite end of the electromagnet 14 and the permanent magnet 13 have the same polarity magnetism, and the electromagnet 14 pushes the permanent magnet 13 to move toward the base 9. The permanent magnet 13 pushes the slide plate 12 to drive the plug 15 to move toward the base 9. Finally, the plug 15 is inserted into the base 9 and the socket 16 at the bottom of the lifting lightning rod 2, so that the lifting lightning rod 2 is further fastened to the base 9, and together with the telescopic rod 5, the wind resistance of the lifting lightning rod 2 is improved;
[0063] When the thunderstorm ends, the electric field strength fed back by the atmospheric electric field meter 3 received by the control box is lower than the set electric field strength, and the control box first sends a closing command to the electromagnet 14, the pushing device and the push-pull electromagnet 19; the electromagnet 14 loses its magnetism when it is powered off, and the repulsive force between the permanent magnet 13 and the electromagnet 14 disappears. Under the elastic force of the first spring 11, the slide plate 12 drives the permanent magnet 13 to move to the right, so that the insertion rod 15 is separated from the socket 16; the output end of the pushing device is retracted into the concave surface of the support block 32; the moving iron core of the push-pull electromagnet 19 is retracted into the slide rail 602;
[0064] Then the control box sends a reverse operation command to the motor and sends a retraction command to the telescopic rod 5. The motor drives the inverted U-shaped slider 601 to move to the right, and the telescopic rod 5 retracts to gradually change the lifting lightning rod 2 from a vertical state to a horizontal state; if the lifting lightning rod 2 is in an extended state when the lifting lightning rod 2 is in a vertical state, the control box will also send a reverse operation command to the stepping motor of the driving device of the lifting lightning rod 2 when sending a retraction command to the telescopic rod 5 to make the lifting lightning rod 2 retract.
[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
