Technical Field

[0001] The present application relates to the technical field of ring network boxes, and in particular to a highly integrated primary and secondary fusion ring network box. Background Art

[0002] The primary-secondary integrated ring network box is a complete set of distribution equipment that integrates primary equipment (such as switchgear, circuit breakers, etc.) with secondary equipment (such as protection, measurement, and control equipment, etc.), aiming to improve the automation level and operational reliability of the distribution network.

[0003] In the related art, a ring main unit includes a cabinet body and a cabinet door. The cabinet door is rotatably connected to the cabinet body. The cabinet body is provided with a receiving slot for placing power supply components, and the cabinet body is provided with a heat dissipation hole connected to the receiving slot.

[0004] Most ring network boxes are installed outdoors. If the electrical components inside the ring network box catch fire due to aging lines, other electrical components in the ring network box are also easily damaged because they are also inside the ring network cabinet, affecting the normal use of the ring network cabinet, and even other electrical components may catch fire, making the fire situation worse. Summary of the Invention

[0005] In order to improve the problem that other electrical components inside the ring network cabinet are easily damaged, the present application provides a highly integrated primary and secondary fusion ring network box.

[0006] This application provides a highly integrated primary and secondary fusion ring network box, which adopts the following technical solutions: A highly integrated primary and secondary fusion ring network box comprises a cabinet body and a cabinet door, wherein the cabinet door is rotatably connected to the cabinet body, a receiving groove for placing power supply components is provided on the cabinet body, a sliding bar is slidably connected to the cabinet body, a plurality of drop holes are provided on the sliding bar, and the drop holes are distributed along the length direction of the sliding bar, the cabinet body is provided with a driving structure for driving the sliding bar to move, and the driving structure is used to start when the temperature inside the receiving groove rises sharply, a plurality of fireproof belts are rotatably connected to the cabinet body, the two ends of the fireproof belts respectively abut the groove wall and the cabinet door along the length direction of the receiving groove, and the fireproof belts can pass through the drop holes; when a fire occurs in the cabinet body, the fireproof belts can fall from the drop holes, and two adjacent fireproof belts can shield the electrical components in the middle.

[0007] By adopting the above technical solution, if a fire occurs inside the cabinet, the temperature inside the cabinet will rise sharply. At this time, the driving structure can drive the sliding bar to move, allowing the fireproof belt to pass through the drop hole, so that the fireproof belt can fall smoothly. In addition, the two ends of the fireproof belt respectively abut the groove wall and the cabinet door along the length direction of the accommodating groove, so that the fireproof belt can limit the air circulation in the cabinet, reduce the oxygen from other parts entering the fire area and causing a larger fire, and realize that the two adjacent fireproof belts can protect the electrical components in the middle, prevent the burning electrical components from transmitting the fire source to other electrical components, reduce the loss of the ring network box, and reduce the possibility of damage to other electrical components.

[0008] Optionally, multiple fire extinguishing bags are slidably connected in the receiving groove, and the fire extinguishing bags are located between two adjacent fire protection belts. Multiple blades are provided in the receiving groove, and the blades are located on the moving path of the fire extinguishing bag; when the fire extinguishing bag abuts the blades, the fire extinguishing bag can extinguish the fire inside the receiving groove.

[0009] By adopting the above technical solution, when a fire occurs inside the cabinet, the fire extinguishing bag is located between two adjacent fire protection belts, and the staff can slide the fire extinguishing bag. Since the blade is located on the moving path of the fire extinguishing bag, the blade can cut the fire extinguishing bag, so that the fire extinguishing bag can extinguish the fire inside the receiving slot, reducing the impact of the fire on the ring network box.

[0010] Optionally, the cabinet body is provided with a through hole connected to the accommodating groove, and there are multiple through holes. The through holes are located between two adjacent fire protection belts, and a movable bar is slidably connected to the hole wall of the through hole; when the inside of the cabinet body is on fire, the movable bar can protrude from the through hole.

[0011] By adopting the above technical solution, when a fire occurs inside the cabinet, the fireproof belt falls down. At this time, the air inside the cabinet expands due to the heat. Since the movable strip is slidably connected to the perforation, the air can drive the movable strip to protrude through the perforation, so that the staff can directly observe which part of the movable strip protrudes from the cabinet to know which part of the cabinet is on fire, so that the staff can extinguish the fire in a more targeted manner.

[0012] Optionally, a movable spring is provided in the accommodating groove, and a movable plate is provided on the movable spring. The movable spring drives the movable plate to move toward the side away from the fire extinguishing bag, and the movable bar is located on the moving path of the fire extinguishing bag; when the movable bar protrudes through the perforation, the movable bar is not on the moving path of the fire extinguishing bag, and the fire extinguishing bag can squeeze the blade.

[0013] By adopting the above technical solution, since the moving bar is located on the moving path of the fire extinguishing bag, the moving bar can limit the movement of the fire extinguishing bag toward the blade, so that the fire extinguishing bag will not be cut by the blade under normal circumstances; if there is a fire inside the cabinet, the moving bar protrudes from the cabinet. At this time, the moving bar is not on the moving path of the fire extinguishing bag, so that the moving spring can drive the moving plate to move, and the moving plate drives the fire extinguishing bag to move toward the blade, so that the blade cuts the fire extinguishing bag, so that the fire extinguishing bag can automatically extinguish the fire without the need for staff to manually slide the fire extinguishing bag, further improving the speed of fire extinguishing.

[0014] Optionally, a baffle is provided on the moving bar, and the baffle can cover the perforated opening.

[0015] By adopting the above technical solution, the baffle blocks the opening of the perforation. If it rains outside, rainwater is not easy to directly enter the receiving groove through the perforation, thereby reducing the erosion of external rainwater on electrical components.

[0016] Optionally, a plurality of heat dissipation holes are provided on the cabinet body, and the plurality of heat dissipation holes are connected to the receiving groove. A plurality of limit plates are slidably connected to the receiving groove, and the limit plates are used to block the heat dissipation holes. A limit block is provided on the limit plate, and the limit block is located on the moving path of the fireproof belt; when the fireproof belt falls, the limit plate blocks the opening of the heat dissipation hole.

[0017] By adopting the above technical solution, when the fireproof belt falls, since the limit block is located on the moving path of the fireproof belt, the fireproof belt can drive the limit plate to move through the limit block, so that the limit plate can block the heat dissipation holes, reducing the air exchange between the inside and outside of the cabinet, making it difficult for the oxygen inside the receiving groove to be replenished, reducing the possibility of further expansion of the fire; when there is no fire in the cabinet, the limit plate does not block the heat dissipation holes, allowing the heat dissipation holes to maintain air circulation between the inside and outside of the cabinet, so as to maintain the normal heat dissipation effect of the ring network cabinet.

[0018] Optionally, a first magnet is provided on the limiting block, and a second magnet is provided on the fireproof belt, and the second magnet attracts the first magnet; when the fireproof belt is reset, the limiting plate does not block the heat dissipation hole.

[0019] By adopting the above technical solution, when the fireproof belt is reset, the second magnet attracts the first magnet, allowing the fireproof belt to drive the limit block to move, so that the limit plate does not block the heat dissipation hole, allowing air circulation inside and outside the cabinet.

[0020] Optionally, a rotating gear is provided on the fireproof belt, and an operating belt is provided on the cabinet body. The rotating gear is meshedly connected to the operating belt, and the operating belt is used to drive the fireproof belt to reset.

[0021] By adopting the above technical solution, the rotating gear is engaged and connected to the operating belt. When the staff rotates the operating belt, the operating belt can drive the rotating gear to rotate, so that multiple fire belts can be reset, and the staff does not need to drive a separate fire belt to rotate, reducing the staff's operating steps to achieve synchronous reset of multiple fire belts.

[0022] Optionally, a movable block is provided on the fireproof belt, and a plurality of movable grooves are opened on the groove wall of the accommodating groove, and the movable block can slide in the movable grooves.

[0023] By adopting the above technical solution, the movable block slides in the movable groove, so that the fireproof belt is not easily bent during the falling process, allowing the fireproof belt to fall stably and avoiding the fireproof belt from bending and failing to seal the electrical components in the middle.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. If a fire occurs inside the cabinet, the temperature inside the cabinet will rise sharply. At this time, the driving structure can drive the sliding bar to move, allowing the perforations to align with the fireproof belt, so that the fireproof belt can fall smoothly. In addition, the two ends of the fireproof belt respectively abut the two sides of the accommodating groove along the length direction, so that the fireproof belt can limit the air circulation in the cabinet, so that the two adjacent fireproof belts can protect the electrical components in the middle, preventing the burning electrical components from transmitting the fire source to other electrical components, reducing the loss of the ring network box, and reducing the possibility of damage to other electrical components.

[0025] 2. Since the moving bar is located on the moving path of the fire extinguishing bag, the moving bar can limit the movement of the fire extinguishing bag toward the blade, so that the fire extinguishing bag will not be cut by the blade under normal circumstances; if there is a fire inside the cabinet, the moving bar protrudes from the cabinet. At this time, the moving bar is not in the moving path of the fire extinguishing bag, so that the moving spring can drive the moving plate to move, so that the moving plate drives the fire extinguishing bag to move toward the blade, so that the blade cuts the fire extinguishing bag, so that the fire extinguishing bag can automatically extinguish the fire, and there is no need for staff to manually slide the fire extinguishing bag, thereby further improving the speed of fire extinguishing.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] This embodiment discloses a highly integrated primary and secondary fusion ring network box. Figure 1 and Figure 2 A highly integrated primary and secondary integrated ring main unit (RMU) box comprises a cabinet body 1 and a cabinet door 2, wherein the cabinet door 2 is rotatably connected to the cabinet body 1. The cabinet body 1 is provided with a receiving slot 11 for placing power supply components, and the receiving slot 11 extends along the length of the cabinet body 1. The ring main unit (RMU) in this application forms a complete power device by highly integrating the primary and secondary devices.

[0030] Reference Figure 1 and Figure 2 The cabinet body 1 has a plurality of placement slots 12 formed on its surface. These slots 12 are arranged in an array along the length of the cabinet body 1 and are all connected to the receiving slot 11. A rotating rod 121 is rotatably connected within the placement slot 12. A fireproof strip 122 is fixedly connected to the outer surface of the rotating rod 121. One end of the fireproof strip 122 abuts against the slot wall of the receiving slot 11 along the length of the cabinet body 1, and the other end abuts against the cabinet door 2. This allows the fireproof strip 122 to restrict air circulation and fire spread within the receiving slot 11, thereby protecting the electrical components between two adjacent fireproof strips 122.

[0031] Reference Figure 2 and Figure 3 A movable block 123 is fixedly connected to the end surface of the fireproof belt 122 away from the rotating rod 121, and a plurality of movable grooves 124 are opened on the groove wall of the accommodating groove 11. The movable grooves 124 extend in the vertical direction, and the plurality of movable grooves 124 are distributed in an array along the length direction of the cabinet 1.

[0032] Reference Figure 3A rotating gear 13 is fixedly connected to the end surface of the rotating rod 121. An operating slot is formed on the cabinet 1, which connects to the multiple placement slots 12 and extends along the length of the cabinet 1. An operating belt 131 is rotatably connected in the operating slot, and the multiple rotating gears 13 are all meshed and connected to the operating belt 131.

[0033] Reference Figure 1 and Figure 3 The cabinet 1 is provided with an operation hole connected to the operation slot. An operation block 132 is fixedly connected to the operation belt 131. The operator can rotate the operation block 132 to rotate the operation belt 131, thereby allowing the operation belt 131 to drive the multiple fire protection belts 122 to move through the rotating gear 13.

[0034] Reference Figure 2 and Figure 3 The cabinet 1 is provided with a driving structure 14, which includes a driving member and a plurality of sensors. The sensor is used to detect the temperature inside the cabinet 1, and the sensor is fixedly connected to the groove wall of the accommodating groove 11. The driving member is a driving cylinder. The driving cylinder is fixedly connected to the groove wall of the accommodating groove 11, and the sensor is electrically connected to the driving cylinder. A sliding bar 141 is fixedly connected to the driving shaft of the driving cylinder, and the sliding bar 141 extends along the length direction of the cabinet 1. A plurality of drop holes 142 are provided on the surface of the sliding bar 141 facing the ground, and the plurality of drop holes 142 are distributed in an array along the length direction of the sliding bar 141, and the drop holes 142 are for one end of the fire protection belt 122 to pass through.

[0035] Reference Figure 2 and Figure 3 When a fire occurs inside the cabinet 1, the sensor detects a sharp rise in temperature, activating the drive cylinder. This activates the slide bar 141, which moves the drop hole 142 directly below the fire barrier 122. This allows the fire barrier 122 to drop from the drop hole 142, allowing two adjacent fire barriers 122 to protect the electrical components between them and reduce the spread of the fire source from the burning part to other electrical components. When there is no fire inside the cabinet 1, the drive cylinder is not activated, and the slide bar 141 blocks the openings of the multiple placement slots 12, i.e., the slide bar 141 abuts the fire barrier 122, preventing it from falling.

[0036] Reference Figure 2 and Figure 4, a plurality of heat dissipation holes 15 are provided on the cabinet body 1, and the plurality of heat dissipation holes 15 are all connected to the receiving groove 11, and the plurality of heat dissipation holes 15 are divided into a plurality of groups. When the fireproof belt 122 is in the state of being dropped, each group of heat dissipation holes 15 is located between two adjacent fireproof belts 122; or each group of heat dissipation holes 15 is located between the fireproof belt 122 and the groove wall of the receiving groove 11, so as to realize the separation of different groups of heat dissipation holes 15 by the fireproof belt 122. A plurality of limiting grooves 151 are provided on the groove wall of the receiving groove 11, and each limiting groove 151 is respectively connected to a different group of heat dissipation holes 15. A limiting plate 152 is slidably connected to the groove wall of the limiting groove 151, and the limiting plate 152 can block the heat dissipation holes 15. When the limiting plate 152 is only subjected to gravity, the limiting plate 152 does not block the heat dissipation holes 15.

[0037] Reference Figure 3 and Figure 4 , a limiting block 153 is fixedly connected to the surface of the limiting plate 152 away from the heat dissipation hole 15, a first magnet 154 is fixedly connected to the surface of the limiting block 153, and the limiting block 153 is located on the moving path of the fireproof belt 122. A second magnet 155 is fixedly connected to the surface of the fireproof belt 122, and the second magnet 155 can absorb the first magnet 154. When the fireproof belt 122 falls, the fireproof belt 122 abuts against the limiting block 153, so that the limiting plate 152 blocks the heat dissipation hole 15. When the fireproof belt 122 is reset, the fireproof belt 122 absorbs the first magnet 154 through the second magnet 155 to drive the limiting block 153 to move, so that the limiting plate 152 does not block the heat dissipation hole 15.

[0038] Reference Figure 3 and Figure 5 A movable spring 16 is fixedly connected to the wall of the placement groove 12, and a movable plate 161 is fixedly connected to the movable spring 16. A fire extinguishing bag 162 is detachably connected to the surface of the movable plate 161. The fire extinguishing bag 162 can absorb oxygen in the air, and the interior of the fire extinguishing bag 162 is carbon black and defective carbon material.

[0039] Reference Figure 3 and Figure 5 Two blades 163 are fixedly attached to the wall of the placement slot 12. The movable spring 16 drives the fire extinguishing bag 162 toward the blades 163, that is, the blades 163 are located in the moving path of the fire extinguishing bag 162. When the blades 163 pierce the fire extinguishing bag 162, the movable spring 16 is in a non-stressed state; when the fire extinguishing bag 162 does not abut the blades 163, the movable spring 16 is in a compressed state.

[0040] Reference Figure 3 and Figure 5The cabinet body 1 is provided with a plurality of through-holes 164, each of which communicates with a different placement slot 12. A movable bar 165 is slidably connected to the wall of each through-hole 164. The movable bar 165 protrudes out of the through-hole 164 and intersects the movement path of the fire extinguishing bag 162. A baffle 166 is fixedly connected to the surface of the movable bar 165. The baffle 166 can block the opening of the through-hole 164, thereby shielding the fire extinguishing bag 162 from rainwater.

[0041] Reference Figure 3 and Figure 5 When a fire occurs inside the cabinet 1, the heated air collides with the moving bar 165, pushing it out of the cabinet 1. At this point, the moving bar 165 is not in the path of the fire extinguishing bag 162. The moving spring 16 can drive the fire extinguishing bag 162 to move, allowing the blade 163 to cut the fire extinguishing bag 162. When there is no fire inside the cabinet 1, the moving bar 165 falls due to gravity, i.e., the moving bar 165 does not protrude from the cabinet 1. The moving bar 165 is in the path of the fire extinguishing bag 162, and the fire extinguishing bag 162 does not abut the blade 163.

[0042] The implementation principle of a highly integrated primary and secondary fusion ring network box in an embodiment of the present application is as follows: when a fire occurs inside the cabinet 1, the sensor detects a sharp increase in temperature, and the sensor starts the driving cylinder, which drives the sliding bar 141 to move, allowing the fireproof belt 122 to fall from the perforation 164. At this time, the fireproof belt 122 abuts against the limit block 153 and moves, allowing the limit plate 152 to block the heat dissipation hole 15, and then the moving bar 165 protrudes from the outside of the cabinet 1, so that the moving spring 16 drives the fire extinguishing bag 162 to move through the moving plate 161, allowing the fire extinguishing bag 162 to be cut by the blade 163, thereby opening the fire extinguishing bag 162 and allowing the fire extinguishing bag 162 to be used.
