Description

Technical Field

[0001] The invention relates to the technical field of substations, and in particular to an intelligent monitoring device for lightning protection and grounding of a box-type substation. Background Art

[0002] In today's complex and huge power supply system, box-type substations play an extremely critical role. They bear the heavy responsibility of power distribution and conversion. The characteristics of their outdoor installation make them inevitably face the threat of lightning. The super-strong instantaneous current carried by lightning is like a "bomb" that may explode at any time. It can drive straight into the power transmission line and can also penetrate into the box-type substation with the help of the grounding system. Once the invasion is successful, many precision electrical equipment in the station will be the first to bear the brunt and suffer serious damage, resulting in power supply interruption. In the past, the maintenance of lightning protection and grounding of box-type substations was mainly completed by manual regular inspections, but the manual inspection method is inefficient. Each inspection requires a lot of manpower, material resources and time. In addition, due to the long detection cycle, real-time monitoring cannot be achieved. Many potential lightning protection and grounding hazards cannot be discovered and handled in time for a long time.

[0003] For example, an intelligent grounding monitoring device with a Chinese announcement number of CN110850336A has the following description: "The present invention discloses an intelligent grounding monitoring device, including: a housing, a monitoring main control board arranged in the housing, and a high-precision overvoltage, overcurrent, and leakage current three-in-one sensor electrically connected to the monitoring main control board; the monitoring main control board includes: a main control PCB board and a display PCB board; the main control PCB board uses a high-performance main control chip to receive and convert and process data collected by the high-precision overvoltage, overcurrent, and leakage current three-in-one sensor to calculate the lightning current amplitude, overvoltage amplitude, and leakage current amplitude." However, the existing device has the following shortcomings during use: During use, the existing intelligent grounding monitoring device can automatically monitor the grounding reliability status of the panel cabinet and secondary equipment online, and has a remote fault alarm function. Timely discovery of the fault point is conducive to timely processing, effectively improving maintenance efficiency and improving production safety level. However, during use, the device needs to be carried or transported to the substation for installation and use. When carrying or transporting, the device is not equipped with a special protective dustproof structure, which may cause internal electrical components to malfunction due to external reasons such as collision. In addition, dust is easy to adhere to the circuit boards and electrical components inside the device during carrying or transportation, which can easily cause short circuit faults and cause detection errors.

[0004] Therefore, we propose an intelligent monitoring device for lightning protection and grounding of box-type substations to solve the above-mentioned problems. Summary of the invention

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 - 9 shown, the present invention provides a technical solution: a box-type substation lightning protection and grounding intelligent monitoring device, including a protective housing 1, a telescopic protection mechanism 2 is arranged inside the protective housing 1, a driving mechanism 3 is arranged on one side of the protective housing 1, a clamping and fixing mechanism 4 is arranged on the top of the telescopic protection mechanism 2, a lightning protection and grounding intelligent monitoring mechanism 5 is arranged on the top of the clamping and fixing mechanism 4, and a plug anti-loosening mechanism 6 is arranged on one side of the lightning protection and grounding intelligent monitoring mechanism 5; The telescopic protection mechanism 2 includes two first limiting grooves 201 which are provided on the inner side of the protection housing 1. A first threaded rod 202 is rotatably connected in one of the first limiting grooves 201, and a fixed rod 203 is fixedly connected in the other first limiting groove 201. Two moving blocks 204 are sleeved on the outer surfaces of the first threaded rod 202 and the fixed rod 203. A moving platform 205 is fixedly connected between the two moving blocks 204. Two protection covers 206 are hinged to the top of the protection housing 1. Four dovetail grooves 207 are provided on one side of the two protection covers 206. Four dovetail blocks 208 are slidably connected in the four dovetail grooves 207. Four first connecting rods 209 are hinged between the four dovetail blocks 208 and the moving platform 205.

[0023] As Figure 1 , Figure 4 and Figure 5 shown, the driving mechanism 3 includes a fixed housing 301 which is fixedly connected to one side of the protection housing 1. A rotating rod 302 is rotatably connected in the fixed housing 301. One end of the rotating rod 302 movably penetrates through the protection housing 1 and extends into one of the first limiting grooves 201. Two bevel gears 303 are fixedly connected to the outer surface of the first threaded rod 202 at one end of the rotating rod 302. The two bevel gears 303 are meshed. Through the meshing of the bevel gears 303 fixedly connected to the outer surfaces of the rotating rod 302 and the first threaded rod 202, when the rotating rod 302 is rotated, the rotation of the rotating rod 302 can be transmitted to the first threaded rod 202, thereby driving the first threaded rod 202 to rotate, providing a power source for the movement of the moving blocks 204 and the moving platform 205 in the telescopic protection mechanism 2, ensuring the smooth operation of the telescopic protection mechanism 2, and realizing the precise opening and closing actions of the protection cover 206.

[0024] As Figure 4 and Figure 5 shown, a worm gear 304 is fixedly sleeved on the outer surface of the rotating rod 302. A worm 305 is rotatably connected in the fixed housing 301. The worm 305 is meshed with the worm gear 304. One end of the worm 305 movably penetrates through the fixed housing 301 and is fixedly connected with a first rotating cap 306. By using the transmission mode of the worm gear 304 and the worm 305, it has a large transmission ratio, can achieve precise regulation of the rotation speed of the first threaded rod 202, and has a self-locking property in one direction. The operator can easily and labor-savingly control the rotation of the worm 305 by rotating the first rotating cap 306, thereby precisely controlling the rotation of the worm gear 304 and the rotating rod 302, and finally finely adjusting the lifting height of the moving platform 205 to facilitate the adjustment of the opening and closing of the protection cover 206.

[0025] As Figure 1 , Figure 5 , Figure 8 and Figure 9As shown in the figure, the clamping and fixing mechanism 4 includes a placement shell 401. The placement shell 401 is fixedly connected to the top of the moving platform 205. A rotating shaft 402 is rotatably connected inside the placement shell 401. A rotating plate 403 is fixedly sleeved on the outer surface of the rotating shaft 402. The rotating plate 403 is rotatably connected to the placement shell 401 through the rotating shaft 402. When the rotating shaft 402 is rotated, the rotating plate 403 can rotate around the rotating shaft 402, providing an adjustable power structure for clamping and fixing the lightning protection and grounding intelligent monitoring mechanism 5.

[0026] As Figure 1 , Figure 8 and Figure 9 shown in the figure, two sliding grooves 404 are opened at the top of the placement shell 401. Two clamping plates 405 are slidably connected in the two sliding grooves 404. Two second connecting rods 406 are hinged to the top of the rotating plate 403. One end of the two second connecting rods 406 away from the rotating plate 403 is hinged to the two clamping plates 405. When the rotating plate 403 rotates, the two clamping plates 405 can be driven to move relatively in the sliding grooves 404 through the second connecting rods 406, facilitating the two clamping plates 405 to flexibly adjust the clamping distance according to the size of the lightning protection and grounding intelligent monitoring mechanism 5, so as to realize the stable clamping and fixing of monitoring mechanisms of different specifications, greatly improving the adaptability of the device to different monitoring mechanisms.

[0027] As Figure 1 , Figure 8 and Figure 9 shown in the figure, a fixing plate 407 is fixedly connected to the top of the placement shell 401. A second threaded rod 408 is threadedly connected to one side of the fixing plate 407. One end of the second threaded rod 408 is movably connected to one of the clamping plates 405. A second rotating cap 409 is fixedly installed at the other end of the second threaded rod 408. When the rotating plate 403 rotates, the operator can rotate the second rotating cap 409 to make the second threaded rod 408 rotate. Since the second threaded rod 408 is threadedly connected to the fixing plate 407, during the rotation process, the second threaded rod 408 can push the clamping plate 405 movably connected to it to move in the sliding groove 404. Combining the way that the rotating plate 403 drives the other clamping plate 405 to move, the distance between the clamping plates 405 can be finely adjusted more precisely, further improving the stability and accuracy of clamping and fixing the lightning protection and grounding intelligent monitoring mechanism 5, ensuring that the monitoring mechanism will not shake or displace in the device.

[0028] As Figure 2 and Figure 3As shown, the lightning protection and grounding intelligent monitoring mechanism 5 includes a monitoring housing 501, a monitoring main control board disposed inside the protection housing 1, and a high-precision lightning protection and grounding parameter integrated monitoring sensor 507 electrically connected to the monitoring main control board. The high-precision lightning protection and grounding parameter integrated monitoring sensor 507 is connected to the protection housing 1 using a six-core aviation plug. On one side of the monitoring housing 501, there are respectively arranged a TFT display screen 502, a key circuit 504, an external interface module 505, and a temperature and humidity acquisition module 506. On one side of the TFT display screen 502, there is an indicator light 503. By integrating a resistance sensor, a lightning current sensor, and an overvoltage sensor through the high-precision lightning protection and grounding parameter integrated monitoring sensor 507, it is used to collect the grounding resistance, the number of lightning strikes, and the lightning strike intensity, achieving comprehensive and accurate monitoring and display of the lightning protection and grounding parameters of the box-type substation. The high-precision lightning protection and grounding parameter integrated monitoring sensor 507 can accurately collect the parameters related to lightning protection and grounding. The monitoring main control board processes and analyzes the collected data. The TFT display screen 502 intuitively shows the monitoring data to the operator. The key circuit 504 facilitates the operator to perform operations and settings. The external interface module 505 consists of two-way remote signaling dry contacts and two-way communication serial ports. The two-way remote signaling dry contacts are monitored through the switch quantity input of external devices and are used for the input of the lightning protection device status to achieve the fault alarm of the overvoltage protection device. The two-way communication serial ports use the standard RS485 interface for data communication and are correspondingly connected to the wireless module built in the monitoring main control board to achieve wireless communication while supporting the wired communication method. The temperature and humidity acquisition module 506 can monitor the temperature and humidity environment inside the device in real time. The indicator light 503 can intuitively display the working status of the device. At the same time, the externally set external interface module 505 and temperature and humidity acquisition module 506 are connected through a standardized interface, which is convenient for operating a certain module separately during installation, maintenance, and upgrade without the need to disassemble the device as a whole, improving the work efficiency. The high-precision lightning protection and grounding parameter integrated monitoring sensor 507 is connected to the protection housing 1 using a six-core aviation plug, which facilitates quick operation of the sensor and reduces the maintenance difficulty. Both the protection housing 1 and the monitoring housing 501 are made of high-strength and corrosion-resistant alloy materials to further improve their anti-external impact and anti-corrosion capabilities. At the same time, a sealing rubber ring is added inside the monitoring housing 501 to optimize the sealing structure to ensure that the internal electronic components are not eroded when the device faces bad weather such as rain and sand, guaranteeing the long-term stable operation of the monitoring device.

[0029] As Figure 6 and Figure 7As shown, the plug anti-loosening mechanism 6 includes a linear guide rail 601. The linear guide rail 601 is installed on one side of the monitoring housing 501. A slider 602 is slidably connected to the linear guide rail 601. A pressing block 603 is fixedly connected to the bottom of the slider 602. Through the cooperation of the linear guide rail 601 and the slider 602, the pressing block 603 can stably slide up and down on the linear guide rail 601. When inserting or removing a six-core aviation plug, the operator can control the position of the slider 602 on the linear guide rail 601 to conveniently drive the pressing block 603 to move, so as to realize the anti-loosening function of the plug by using the pressing block 603 to push the wedge block 607.

[0030] As Figure 6 and Figure 7 shown, a support shell 604 is fixedly connected to one side of the monitoring housing 501. A second limiting groove 605 is opened inside the support shell 604. A movable block 606 is slidably connected in the second limiting groove 605. The top of the movable block 606 movably penetrates through the support shell 604 and is fixedly connected to a wedge block 607. A movable rod 608 is fixedly connected to one side of the movable block 606. When the pressing block 603 moves downward, it can push the wedge block 607. Since the wedge block 607 is fixedly connected to the movable block 606 and the movable block 606 slides in the second limiting groove 605, the movable rod 608 is driven to move, and the vertical downward movement of the pressing block 603 can be converted into the horizontal movement of the movable rod 608, providing power transmission for the subsequent movement of the anti-loosening arc plate 609 to realize the anti-loosening pressing function of the six-core aviation plug.

[0031] As Figure 6 and Figure 7 shown, one end of the movable rod 608 movably penetrates through the support shell 604 and is fixedly connected to an anti-loosening arc plate 609. A telescopic rod 610 is fixedly connected between the support shell 604 and the movable block 606. A return spring 611 is sleeved on the outer surface of the telescopic rod 610. After the six-core aviation plug is inserted, the slider 602 is released. Under the elastic force of the return spring 611, the movable rod 608 drives the anti-loosening arc plate 609 to move to press the plug. The telescopic rod 610 plays a guiding and supporting role to ensure the stability of the movement of the movable block 606 and the anti-loosening arc plate 609, effectively preventing the six-core aviation plug from loosening during use, ensuring the stable and reliable connection between the high-precision lightning protection grounding parameter integration monitoring sensor 507 and the monitoring housing 501, thus ensuring the accuracy of monitoring data transmission, avoiding data transmission interruption or error caused by plug loosening, and improving the reliability and stability of the entire lightning protection grounding intelligent monitoring device.

[0032] Usage method and working principle of this device: When in use, place the entire lightning protection and grounding intelligent monitoring mechanism 5 on the top of the placement shell 401, and then rotate the second rotating cap 409. The second threaded rod 408 rotates. Since the second threaded rod 408 is threadedly connected to the fixed plate 407, it will push the clamping plate 405 movably connected to it to move in the chute 404. At the same time, rotate the rotating shaft 402 to make the rotating plate 403 rotate around the rotating shaft 402, and drive another clamping plate 405 to move relatively in the chute 404 through the second connecting rod 406. According to the size of the lightning protection and grounding intelligent monitoring mechanism 5, adjust the clamping distance between the two clamping plates 405 to ensure that the lightning protection and grounding intelligent monitoring mechanism 5 is stably clamped and fixed on the placement shell 401. At the same time, the high-precision lightning protection and grounding parameter integrated monitoring sensor 507 can be placed in the storage box on one side of the monitoring shell 501 for storage. Subsequently, the operator rotates the first rotating cap 306, and the first rotating cap 306 drives the worm 305 to rotate. Since the worm 305 meshes with the worm gear 304, the worm gear 304 and the rotating rod 302 rotate. The rotating rod 302 meshes with the bevel gear 303 on the outer surface of the first threaded rod 202, so the first threaded rod 202 rotates accordingly. When the first threaded rod 202 rotates, the moving block 204 sleeved on its outer surface will move along the first limiting groove 201, and at the same time drive the moving platform 205 to move downward, and at the same time drive the entire lightning protection and grounding intelligent monitoring mechanism 5 into the protection shell 1. Push the dovetail block 208 to slide in the dovetail groove 207 through the first connecting rod 209, so that the protection cover 206 closes. At this time, the lightning protection and grounding intelligent monitoring mechanism 5 is located inside the protection shell 1. Subsequently, this device can be carried or transported to the box-type substation. Install this device in a suitable position through the guide rail buckle installed at the bottom of the protection shell 1. Then rotate the first rotating cap 306 in the reverse direction, repeat the above transmission process, make the moving platform 205 rise, and then drive the protection cover 206 to open, and the entire lightning protection and grounding intelligent monitoring mechanism 5 extends out from the inside of the protection shell 1. Then press down the slider 602 by holding the handle on the slider 602, and the slider 602 drives the extrusion block 603 to move downward. The extrusion block 603 pushes the wedge block 607. The wedge block 607 is fixedly connected to the movable block 606. The movable block 606 slides in the second limiting groove 605, drives the movable rod 608 to move, and the movable rod 608 drives the anti-loosening arc plate 609 to move, so as to push the two wedge blocks 607 away from each other, and further make the two anti-loosening arc plates 609 move away from each other. At the same time, the return spring 611 starts to contract under the extrusion of the movable block 606. Then insert the six-core aviation plug of the high-precision lightning protection and grounding parameter integrated monitoring sensor 507 into the interface of the protection shell 1, and then release the handle on the slider 602. Under the elastic force of the return spring 611, the two movable rods 608 drive the two anti-loosening arc plates 609 to move relatively, and press the six-core aviation plug tightly. When it is necessary to pull out the plug, press the wedge block 607 again by holding the handle on the slider 602,The plug can be unplugged, and then the high-precision lightning protection grounding parameter integrated monitoring sensor 507 is installed on the grounding lead of the grounding electrode. After the device is turned on, the high-precision lightning protection grounding parameter integrated monitoring sensor 507 starts to measure and collect lightning protection grounding related parameters such as grounding resistance, lightning strike times, and lightning strike intensity. The monitoring main control board processes and analyzes the collected data. The operator can view the monitoring data through the TFT display screen 502, and perform operations and settings through the key circuit 504. At the same time, the temperature and humidity acquisition module 506 monitors the temperature and humidity environment inside the device in real time, and the indicator light 503 intuitively displays the working state of the device. At the same time, through the external interface module 505, the lightning protection device status monitoring and data communication can be carried out to achieve real-time monitoring.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
