Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically a fireproof busbar segmentation device with a composite insulation layer. Background Technology

[0002] A busbar trunking system is composed of multiple independent busbar trunking units spliced ​​together by connectors or joints. Each unit is called a "segment". The segments are electrically connected by highly conductive and high-temperature resistant connectors or joints to ensure the continuity of current transmission. The connector design must meet the requirements of mechanical strength and electrical insulation. When a segment fails, the power supply to that segment can be quickly cut off to avoid affecting the operation of other segments and improve system reliability. The segment design facilitates fault diagnosis and component replacement without the need for overall shutdown, thus reducing maintenance costs.

[0003] An existing patent (publication number: CN220775331U) discloses a heat dissipation busbar trunking. This busbar trunking uses mounting slots to install and fix a fixed cover and a protective frame. When the cooling fan operates to dissipate heat from the inside of the busbar trunking, the heat is discharged into the casing through evenly distributed heat dissipation slots within the fixed cover. A dustproof net installed within the protective frame protects the busbar trunking from dust entering through the mounting slots and damaging internal components. However, the ventilation openings of this busbar trunking lack fire resistance; if a fire breaks out inside, the flames will spread from the ventilation openings, causing surrounding items to burn and the fire to intensify. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fireproof busbar trunking segmentation device with a composite insulation layer, which effectively solves the problem that the ventilation openings of the existing busbar trunking do not have fireproof capabilities, and when a fire starts inside, the flames will spread out from the ventilation openings, thereby causing the surrounding items to burn and the fire to spread.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof busbar trunking segmentation device with a composite insulation layer, comprising a busbar trunking body, a ventilation frame fixedly installed at the middle of the top of the busbar trunking body, a connecting frame detachably installed at the upper part of the ventilation frame, a dustproof net fixedly installed inside the connecting frame, a cooling fan fixedly installed at the middle of the busbar trunking body, rotating seats fixedly installed on both inner walls of the two sides of the busbar trunking body, fireproof plates rotatably installed on the side of the two rotating seats that are close to each other, a locking rod fixedly installed at one end of the lower end of each of the two fireproof plates, a transmission rod rotatably installed on the side of the two fireproof plates that are far from each other, a limiting sleeve rotatably installed at the lower end of each of the two transmission rods, a limiting slide rod movably inserted into the interior of each of the two limiting slide sleeves, the top ends of the two limiting slide rods fixedly installed on both sides of the bottom of the ventilation frame, a fixing plate fixedly installed at the bottom end of each of the two limiting slide rods, a telescopic spring sleeved on the lower part of the surface of each of the two limiting slide rods, and the two ends of the two telescopic springs fixedly connected to the limiting slide sleeve and the fixing plate respectively;

[0006] Two limiting sleeves are each fixedly mounted with a first fixing ring on the side that is far apart from each other. A fusible rope is fixedly mounted on each of the two first fixing rings. A second fixing ring is fixedly mounted on the side that is far apart from each other of the two fusible ropes. The side that is far apart from each other of the two second fixing rings is fixedly connected to the inner walls of both sides of the busbar trunking body. A composite insulation layer is fixedly mounted on the inner lining of the busbar trunking body. The composite insulation layer is made of epoxy resin and glass fiber. The lower part of the ventilation frame is provided with a buckle assembly that cooperates with the two clamping rods.

[0007] Preferably, the buckle assembly includes a support arm, which is fixedly installed in the lower part inside the ventilation frame. The bottom of the support arm has two sockets, and two metal elastic pieces are symmetrically arranged inside each of the two sockets. Connecting rods are fixedly installed at both ends of one side of the four metal elastic pieces, and the ends of the connecting rods away from the metal elastic pieces are fixedly connected to the inner wall of the socket.

[0008] Preferably, a guide plate is fixedly installed at the center of each of the four metal elastic plates on the side away from the connecting rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the heat inside the busbar trunking body can be discharged by the cooling fan. When the inside of the busbar trunking body catches fire and burns to the ventilation frame, it will burn through the two fuse ropes. After losing the tension of the two fuse ropes, the two telescopic springs will push the limiting slide sleeve to move up along the surface of the limiting slide rod through their own elasticity. When the limiting slide sleeve moves up, it will push the two fireproof plates to rotate up and down along the two rotating seats to close through the transmission rod.

[0010] As the two fireproof plates rotate upwards, they drive the locking rods into the sockets and, under the action of the guide plate, accurately squeeze into the upper part of the metal elastic sheet for locking, thus ensuring the stability of the two fireproof plates when closed. After the two fireproof plates are closed, they can effectively prevent the flames from spreading outwards, providing excellent protection. This also makes the ventilation openings of this busbar duct fireproof, preventing the flames from spreading out of the ventilation openings when a fire starts inside, thus controlling the fire and preventing the surrounding items from burning.

[0020] Depend on Figures 1 to 5 The present invention includes a busbar trunking body 1, a ventilation frame 2 fixedly installed at the center of the top of the busbar trunking body 1, a connecting frame 22 detachably installed at the upper part of the ventilation frame 2, a dustproof net 3 fixedly installed inside the connecting frame 22, a cooling fan 4 fixedly installed at the center of the inside of the busbar trunking body 1, rotating seats 5 fixedly installed on the inner walls of both sides of the busbar trunking body 1, fireproof plates 6 rotatably installed on the side of the two rotating seats 5 that are close to each other, and a clamping rod 12 fixedly installed at one end of the lower end of each of the two fireproof plates 6. Two fireproof boards 6 are rotatably mounted on opposite sides of each other, and a limiting sleeve 8 is rotatably mounted on the lower end of each of the two transmission rods 7. A limiting rod 9 is movably inserted into the interior of each of the two limiting sleeves 8. The top ends of the two limiting rods 9 are fixedly mounted on both sides of the bottom of the ventilation frame 2. A fixing plate 10 is fixedly mounted on the bottom end of each of the two limiting rods 9. A telescopic spring 11 is sleeved on the lower part of the surface of each of the two limiting rods 9. The two ends of the two telescopic springs 11 are fixedly connected to the limiting sleeve 8 and the fixing plate 10 respectively.

[0021] Two limiting sleeves 8 are each fixedly installed with a first fixing ring 13 on the side away from each other. A fusible rope 14 is fixedly installed on each of the two first fixing rings 13. A second fixing ring 15 is fixedly installed on the side away from each other of the two fusible ropes 14. The side away from each other of the two second fixing rings 15 are fixedly connected to the inner walls of both sides of the bus trunking body 1. A composite insulation layer 17 is fixedly installed on the inner lining layer of the bus trunking body 1. The composite insulation layer 17 is made of epoxy resin and glass fiber. The lower part of the ventilation frame 2 is provided with a buckle assembly that cooperates with the two clamping rods 12.

[0022] In use, the heat inside the busbar trunking body 1 can be discharged by the cooling fan 4. When the fire inside the busbar trunking body 1 reaches the ventilation frame 2, it will burn through the two fuse ropes 14. After losing the tension of the two fuse ropes 14, the two telescopic springs 11 will push the limiting sleeve 8 to move up and down along the surface of the limiting slide rod 9 through their own elasticity. When the limiting sleeve 8 moves up, it will push the two fireproof plates 6 to rotate up and down along the two rotating seats 5 through the transmission rod 7 to close. After the two fireproof plates 6 are closed, they can effectively prevent the flame from spreading outward and have very good protective ability. This makes the ventilation opening of the busbar trunking fireproof. When a fire starts inside, it will block the flame from spreading out of the ventilation opening and prevent the surrounding items from burning and control the fire.

[0023] The buckle assembly includes a support arm 16, which is fixedly installed in the lower part inside the ventilation frame 2. The bottom of the support arm 16 has two sockets 18, and two metal elastic pieces 20 are symmetrically arranged inside each of the two sockets 18. Connecting rods 19 are fixedly installed at both ends of one side of each of the four metal elastic pieces 20. The ends of the connecting rods 19 away from the metal elastic pieces 20 are fixedly connected to the inner wall of the socket 18. Guide plates 21 are fixedly installed in the middle of the side of each of the four metal elastic pieces 20 away from the connecting rods 19.

[0024] As the two fireproof plates 6 rotate upwards, they will drive the locking rod 12 into the interior of the socket 18, and simultaneously, under the action of the guide plate 21, they will accurately squeeze into the upper part of the metal elastic sheet 20 for locking, thereby ensuring the stability of the closure of the two fireproof plates 6.
