Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically a safety power distribution switchgear. Background Technology

[0002] The main function of switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components of switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices. Switchgear can be classified in many ways, such as by the circuit breaker installation method (removable switchgear and fixed switchgear); or according to the cabinet structure (open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear); and according to voltage level (high-voltage switchgear, medium-voltage switchgear, and low-voltage switchgear).

[0003] However, traditional switch cabinets may catch fire due to overheating during use, which could lead to fires in the internal control components. If the fire is not detected in time, it can spread further and cause greater losses. Furthermore, when maintenance personnel are inspecting the control components inside the cabinet, the cabinet door may suddenly close during the inspection process, affecting the maintenance personnel. In addition, most control components are installed using bolts and nuts. Since the nuts need to be tightened on the back of the control components, the control components can obstruct the personnel when being tightened, making installation difficult. Summary of the Invention

[0006] The mounting structure includes a slide rod, and the warning structure is provided with a slide rod. A mounting bracket is rotatably connected to the slide rod, and two push blocks are fixedly connected to the mounting bracket. Two rotating rods are rotatably connected to the slide rod, and the ends of the push blocks extend into the interior of the rotating rods. The mounting bracket and the rotating rods abut against each other.

[0007] Specifically, the push block has a cylindrical structure, and a first junction box is fixedly connected to the mounting bracket.

[0008] Specifically, the warning structure includes two sliding seats, two sliding seats are slidably connected to the cabinet body, the same sliding rod is slidably connected to the two sliding seats, a pulling rope is fixedly connected to the sliding seat, the two pulling ropes are fixedly connected to the same cross bar, three second connecting blocks are fixedly connected to the cabinet body, a screw rod is rotatably connected to the middle second connecting block, first guide rods are fixedly connected to the two second connecting blocks at both ends, the same cross bar is slidably connected to the two first guide rods, the screw rod is threadedly connected to the cross bar, the pulling rope is wound around the guide shaft, the guide shaft is rotatably connected to the first connecting block, the first connecting block is fixedly connected to the cabinet body, and a first return spring abuts between the first connecting block and the sliding seat.

[0009] Specifically, a handle is slidably connected to the screw rod, the width of both ends of the cross section of the handle is greater than that of the sliding seat. Specifically, one end of the cross section of the sliding seat is in a swan neck structure, the other end of the cross section of the sliding seat is in a "convex" shape structure, and the cross section of the second connecting block is in a U-shaped structure.

[0010] Specifically, the clamping structure includes a pull rod, the pull rod is slidably connected to the cabinet body, a resisting block is fixedly connected to the pull rod, the resisting block is slidably connected to the sliding rod and abuts against the clamping block, one end of the clamping block is clamped with the mounting bracket and the other end is clamped with the clamping groove, two clamping grooves are provided on one of the sliding seats, a second return spring abuts between the resisting block and the sliding rod, and a third return spring abuts between the clamping block and the sliding rod.

[0011] Specifically, the depths of the two clamping grooves are different, the end of the cross section of the clamping block is in a trapezoidal structure, and one end of the cross section of the resisting block is in a trapezoidal structure.

[0012] Specifically, the blocking structure includes a blocking rod, two blocking rods are slidably connected to the cabinet body, the blocking rods abut against the sliding seat, and a fourth return spring is fixedly connected between the blocking rods and the cabinet body.

[0013] Specifically, the airtight structure includes a connecting rod, the connecting rod is fixedly connected to the sliding seat, the two connecting rods are fixedly connected to the same sliding plate, four second guide rods penetrate through the sliding plate, the second guide rods are slidably connected to the sliding plate, the four second guide rods are fixedly connected to the cabinet body, and a second sealing ring is clamped on the sliding plate.

[0014] Specifically, the sealing structure includes a sealing door, the sealing door is rotatably connected to the cabinet body, a lock core is installed on the sealing door, and a first sealing ring is clamped on the sealing door.

[0015] The beneficial effects of the present invention are:

[0016] (1) The safety distribution switch cabinet of the present invention can seal the cabinet body through a sealing structure. Multiple ventilation holes opened at the bottom of the cabinet body can connect the air inside the cabinet body with the outside, thereby playing a role in ventilation and heat dissipation. If the control components inside the cabinet body catch fire due to excessive temperature during use, the state of the warning structure will change, thereby driving the airtight structure to seal the ventilation holes, thus forming a sealed space inside the cabinet body. As a result, the outside air cannot enter the inside of the cabinet body. Since there is no gas involved, the flame of the burning object inside the cabinet body will automatically extinguish after a period of time, thereby avoiding further expansion of the fire and reducing losses. That is: the cabinet body can be sealed through the sealing door, and the sealing performance can be improved by the contact between the first sealing ring and the cabinet body, effectively preventing air from entering the inside of the cabinet body from between the sealing door and the cabinet body. Multiple ventilation holes opened at the bottom of the cabinet body can connect the air inside the cabinet body with the outside, thereby playing a role in ventilation and heat dissipation. During use, by rotating the handle The handle rotates the lead screw, which in turn drives the crossbar. This movement of the crossbar, via a pull rope, causes the slide block to slide on the cabinet. The first return spring contracts. When the plug on the first junction box is fully inserted into the second junction box, the handle stops rotating. At this point, both first return springs are compressed, and both pull ropes are taut. Therefore, if the control components inside the cabinet catch fire due to overheating, the nylon pull ropes will burn through. The first return springs will then extend, freeing themselves from the pull rope's tension, and drive the slide block. This movement, via a connecting rod, drives the sliding plate. When the second sealing ring on the sliding plate is pressed against the cabinet, the first return spring stops extending. At this point, the first return spring remains compressed, ensuring the second sealing ring is pressed against the cabinet. External air cannot enter the cabinet, and the burning material inside will automatically extinguish after a period of time due to the absence of gas, thus preventing further fire spread and minimizing damage.

[0017] (2) The safety power distribution switch cabinet of the present invention can block the warning structure through the blocking structure, thereby effectively preventing the warning structure from moving after the state changes, thus improving stability. In addition, the blocking structure can block the warning structure during transportation, thereby effectively preventing the blocking structure from sliding during transportation, thus improving stability. That is, after the fire occurs, the slide stops sliding under the action of the first return spring, and the stop bar will slide on the cabinet under the action of the fourth return spring, thereby blocking the slide and preventing the slide from sliding. In addition, the blocking of the slide by the stop bar during transportation can also prevent the slide from sliding, thereby improving the stability during transportation.

[0018] (3) In the safety distribution switch cabinet of the present invention, when it is necessary to install or repair the control components inside the cabinet, the locking structure is pulled. During the process of pulling the locking structure, the locking structure will disengage from the warning structure. At this time, if the locking structure is pulled again, the locking structure will drive the installation structure to slide on the warning structure. When the installation structure slides to a certain position, the locking structure will re-engage with the warning structure. At this time, the installation structure can rotate. Therefore, the installation structure is rotated at a certain angle so that the back nut of the control component faces the staff, which facilitates the disassembly of the control component and the installation and repair of the control component. When the installation structure slides out, the locking structure will block the sealing structure, which effectively avoids the sealing structure from suddenly closing and affecting the staff, thus improving stability. That is, when it is necessary to install or repair the control components inside the cabinet, the pull rod is pulled. The pull rod drives the block to move. The second return spring extends. The movement of the block will drive the locking block to move away from the slot. The third return spring retracts. When the locking block is completely disengaged from the slot, After the pull rod is released, it will drive the slide rod to move under the action of the pulling force. During the sliding process of the slide rod, the end of the locking block is engaged with the mounting bracket, so the mounting bracket and the slide rod will not rotate. As the slide rod moves, the end of the locking block will face another locking slot. At this time, the locking block will move towards the other locking slot under the action of the third return spring. Since the depth of this locking slot is deeper than the previous locking slot, when one end of the locking block is fully inserted into the locking slot, the other end of the locking block will disengage from the mounting bracket, thereby allowing the mounting bracket to rotate. During the rotation of the mounting bracket, the push block will drive the rotating rod to rotate. The rotating rod will support the mounting bracket, thereby preventing excessive force on the mounting bracket's pivot point and damage. As the mounting bracket rotates, the back of the control element will face the staff, which facilitates the disassembly and assembly of the control element and the maintenance of the control element. When the mounting bracket slides out, the end of the pull rod will be located outside the cabinet. At this time, the pull rod can block the sealing door, thereby preventing the sealing door from suddenly closing during maintenance and affecting the staff, thus improving stability.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1-11As shown, the safety power distribution switch cabinet of the present invention includes a cabinet body 1, a sealing structure 2 on the cabinet body 1, an early warning structure 4 on the cabinet body 1, an installation structure 3 on the early warning structure 4, an airtight structure 5 on the early warning structure 4, a locking structure 6 on the early warning structure 4, a blocking structure 7 on the cabinet body 1, a first junction box 8 on the installation structure 3, and a second junction box 9 on the cabinet body 1.

[0034] Specifically, the mounting structure 3 includes a slide rod 301, and the warning structure 4 is provided with the slide rod 301. A mounting bracket 302 is rotatably connected to the slide rod 301. Two push blocks 303 are fixedly connected to the mounting bracket 302. Two rotating rods 304 are rotatably connected to the slide rod 301. The ends of the push blocks 303 extend into the interior of the rotating rods 304. The mounting bracket 302 abuts against the rotating rods 304. The push blocks 303 have a cylindrical structure. A first junction box 8 is fixedly connected to the mounting bracket 302. The locking structure 6 includes a pull rod 601, and the cabinet 1 is slidably connected to the pull rod 601. A stop block 602 is fixedly connected to the pull rod 601. The stop block 602 is slidably connected to the slide rod 301 and abuts against the locking block 602. 03. One end of the locking block 603 engages with the mounting bracket 302, and the other end engages with the slot 606. One of the slide blocks 401 has two slots 606. The abutment block 602 and the slide rod 301 are abutted by a second return spring 604, and the locking block 603 and the slide rod 301 are abutted by a third return spring 605. The two slots 606 have different depths. The end of the cross-section of the locking block 603 is trapezoidal, and one end of the cross-section of the abutment block 602 is trapezoidal. That is, when it is necessary to install the control element, first connect the external power cord to the second junction box 9, then pull the lever 601. The lever 601 drives the abutment block 602 to move, the second return spring 604 extends, and the movement of the abutment block 602 will drive the locking block 606 to move. 03. As the block moves away from the slot 606, the third return spring 605 contracts. When the block 603 is completely disengaged from the slot 606, the pull rod 601 will drive the slide rod 301 to move under the pull force. During the sliding of the slide rod 301, the end of the block 603 is engaged with the mounting bracket 302, so the mounting bracket 302 and the slide rod 301 will not rotate. As the slide rod 301 moves, the end of the block 603 will face another slot 606. At this time, the block 603 will move towards the other slot 606 under the elastic force of the third return spring 605. Since the depth of this slot 606 is deeper than the previous slot 606, when one end of the block 603 is completely inserted into the slot 606, the other end of the block 603 will be engaged with the mounting bracket 302. The mounting bracket 302 detaches, allowing it to rotate. During rotation, the push block 303 drives the rotating rod 304 to rotate, providing support and preventing excessive stress on the mounting bracket's pivot point. As the mounting bracket 302 rotates, the back of the control element faces the operator, facilitating its installation. The control element's wiring can be connected to the inside of the first junction box 8. When the mounting bracket 302 slides out, the end of the pull rod 601 is outside the cabinet 1, preventing the sealing door 201 from suddenly closing during maintenance and thus improving stability.After all control components are installed, rotate the mounting bracket 302 and return it to its original position. Then, pull the lever 601 with one hand. When the sliding rod 301 can slide on the slide block 401, push the mounting bracket 302 in the opposite direction with the other hand. At this time, the mounting bracket 302 will move towards the inside of the cabinet 1. After the sliding rod 301 has moved a certain distance, release the lever 601 and continue to push the mounting bracket 302. As the sliding rod 301 moves, the locking block 603 will engage with the locking slot 606, thus resetting the mounting bracket 302.

[0035] Specifically, the warning structure 4 includes two sliding seats 401. Two sliding seats 401 are slidably connected to the cabinet body 1. The same sliding rod 301 is slidably connected to the two sliding seats 401. A pulling rope 402 is fixedly connected to the sliding seat 401. The two pulling ropes 402 are fixedly connected to the same cross bar 406. Three second connecting blocks 407 are fixedly connected to the cabinet body 1. A screw rod 408 is rotatably connected to the middle second connecting block 407. First guide rods 410 are fixedly connected to the two second connecting blocks 407 at both ends. The same cross bar 406 is slidably connected to the two first guide rods 410. The screw rod 408 is threadedly connected to the cross bar 406. The pulling rope 402 is wound around the guide shaft 405. The guide shaft 405 is rotatably connected to a first connecting block 404. The first connecting block 404 is fixedly connected to the cabinet body 1. A first return spring 403 is abutted between the first connecting block 404 and the sliding seat 401. A handle 409 is slidably connected to the screw rod 408. The width of both ends of the cross section of the handle 409 is greater than the width of the middle part. One end of the cross section of the sliding seat 401 is in a燕尾状 structure, and the other end of the cross section of the sliding seat 401 is in a "凸" - shaped structure. The cross section of the second connecting block 407 is in a U - shaped structure. The blocking structure 7 includes a blocking rod 701. Two blocking rods 701 are slidably connected to the cabinet body 1. The blocking rod 701 abuts against the sliding seat 401. A fourth return spring 702 is fixedly connected between the blocking rod 701 and the cabinet body 1. The airtight structure 5 includes a connecting rod 501. The connecting rod 501 is fixedly connected to the sliding seat 401. The two connecting rods 501 are fixedly connected to the same sliding plate 502. Four second guide rods 503 penetrate through the sliding plate 502. The second guide rods 503 are slidably connected to the sliding plate 502. The four second guide rods 503 are fixedly connected to the cabinet body 1. A second sealing ring 504 is clamped on the sliding plate 502. The sealing structure 2 includes a sealing door 201. The sealing door 201 is rotatably connected to the cabinet body 1. A lock core 202 is installed on the sealing door 201. A first sealing ring 203 is clamped on the sealing door 201. That is, by rotating the handle 409, the handle 409 drives the screw rod 408 to rotate. The screw rod 408 thread - drives the cross bar 406 to move. The movement of the cross bar 406 will drive the sliding seat 401 to slide on the cabinet body 1 through the pulling rope 402, and the first return spring 403 contracts. When the plug on the first junction box 8 is completely inserted into the second junction box 9, stop rotating the handle 409. At this time, the two first return springs 403 are in a compressed state, and the two pulling ropes 402 are in a taut state. Then, the cabinet body 1 is sealed by the sealing door 201. The airtightness can be improved by the abutment between the first sealing ring 203 and the cabinet body 1, effectively avoiding air from entering the interior of the cabinet body 1 between the sealing door 201 and the cabinet body 1. The air inside the cabinet body 1 can be connected to the outside through multiple ventilation holes opened at the bottom of the cabinet body 1, thus playing a role in ventilation and heat dissipation.When the control components inside cabinet 1 catch fire due to overheating, the pull rope 402, being made of nylon, will burn through after the fire. At this time, the first return spring 403 will extend to release the tension of the pull rope 402, causing the slide 401 to move. The movement of the slide 401 will drive the sliding plate 502 through the connecting rod 501. When the second sealing ring 504 on the sliding plate 502 is pressed against the cabinet 1, the first return spring 403 stops extending. At this time, the first return spring 403 is still in a compressed state, thus ensuring that the second sealing ring 504 is pressed against the cabinet 1. At this time, under the action of the fourth return spring 702, the stop rod 701 will move towards the slide 401 and block the slide 401, thus preventing the slide 401 from sliding and improving stability. At this time, external air cannot enter the interior of cabinet 1. Since there is no gas involved, the flames of the burning objects inside cabinet 1 will automatically extinguish after a period of time, thus preventing the fire from spreading further and reducing losses. ,

[0036] In use, before the control components are installed after the switch cabinet is manufactured, one side of each of the two slides 401 is in contact with the cabinet body 1. The stop bar 701 will block the other side of the slide 401, and the pull rope 402 is in a relaxed state. At this time, because the stop bar 701 blocks the slide 401, the slide 401 will not slide on the cabinet body 1, thereby improving stability. When the control components need to be installed, first connect the external power cord to the second junction box 9, then pull the pull rod 601. The pull rod 601 drives the stop block 602 to move, the second return spring 604 extends, and the movement of the stop block 602 will cause the locking block 603 to move away from the locking slot 606. When the return spring 605 retracts, and the locking block 603 is completely disengaged from the slot 606, the pull rod 601 will drive the slide rod 301 to move under the pull force. During the sliding of the slide rod 301, the end of the locking block 603 is engaged with the mounting bracket 302, so the mounting bracket 302 and the slide rod 301 will not rotate. As the slide rod 301 moves, the end of the locking block 603 will face another slot 606. At this time, the locking block 603 will move towards the other slot 606 under the elastic force of the third return spring 605. Since the depth of this slot 606 is deeper than the previous slot 606, when one end of the locking block 603 is completely inserted into the slot 606, it will lock. The other end of block 603 will disengage from the mounting bracket 302, allowing the mounting bracket 302 to rotate. During the rotation of the mounting bracket 302, the push block 303 will drive the rotating rod 304 to rotate. The rotating rod 304 will support the mounting bracket 302, thus preventing excessive force on the shaft of the mounting bracket 302 and potential damage. As the mounting bracket 302 rotates, the back of the control element will face the operator, facilitating the installation of the control element. The wires of the control element can be connected to the inside of the first junction box 8. When the mounting bracket 302 slides out, the end of the pull rod 601 will be located outside the cabinet 1. At this time, the pull rod 601 can block the sealing door 201, thereby enabling... To avoid the sudden closure of the sealing door 201 during maintenance, which could affect the staff, thus improving stability, after all control components are installed, rotate the mounting bracket 302 and return it to its original position. Then, pull the lever 601 with one hand. When the sliding rod 301 can slide on the slide block 401, push the mounting bracket 302 in the opposite direction with the other hand. At this time, the mounting bracket 302 will move towards the inside of the cabinet 1. After the sliding rod 301 has moved a certain distance, release the lever 601 and continue to push the mounting bracket 302. As the sliding rod 301 moves, the locking block 603 will engage with the locking slot 606, thus resetting the mounting bracket 302.

[0037] Next, by rotating the handle 409, the handle 409 drives the lead screw 408 to rotate. The lead screw 408 threadedly drives the crossbar 406 to move. The movement of the crossbar 406 drives the slide block 401 to slide on the cabinet 1 via the pull rope 402. The first return spring 403 contracts. When the plug on the first junction box 8 is fully inserted into the second junction box 9, the handle 409 stops rotating. At this time, the two first return springs 403 are in a compressed state, and the two pull ropes 402 are in a taut state. Then, the cabinet 1 is sealed by the sealing door 201. The contact between the first sealing ring 203 and the cabinet 1 can improve the sealing performance and effectively prevent air from entering the interior of the cabinet 1 from between the sealing door 201 and the cabinet 1. The multiple ventilation holes opened at the bottom of the cabinet 1 can connect the air inside the cabinet 1 with the outside, thereby playing a role in ventilation and heat dissipation. When the control components inside the cabinet 1 catch fire due to overheating, since the pull rope 402 is made of nylon... Therefore, after a fire occurs, the pull rope 402 will be burned through. At this time, the first return spring 403 will break free from the tension of the pull rope 402 and extend, causing the slide 401 to move. The movement of the slide 401 will drive the sliding plate 502 to move through the connecting rod 501. When the second sealing ring 504 on the sliding plate 502 is pressed against the cabinet 1, the first return spring 403 stops extending. At this time, the first return spring 403 is still in a compressed state, which can ensure that the second sealing ring 504 is pressed against the cabinet 1. At this time, under the action of the fourth return spring 702, the stop rod 701 will move towards the slide 401 and block the slide 401, thus preventing the slide 401 from sliding and improving stability. At this time, external air cannot enter the interior of the cabinet 1. Since there is no gas involved, the flame of the burning object inside the cabinet 1 will automatically extinguish after burning for a period of time, thus preventing the fire from spreading further and reducing losses.
