Description

Technical Field

[0001] This invention relates to the field of busbar technology, specifically to a waterproof and heat-dissipating cover for a conductive busbar split type. Background Technology

[0002] Busbar trunking is a high-efficiency power transmission equipment used for centralized power distribution, replacing traditional cables. It is suitable for high-current, dense power distribution applications. To meet the needs of high-current, low-voltage transmission lines in industrial and civil engineering construction, power distribution designs all adopt busbar trunking systems. In recent years, with the continuous increase in the capacity of transmission and distribution lines, busbar trunking systems have been widely used in engineering projects. The top plate of the busbar trunking is an important component of the busbar trunking system, mainly used to protect the internal conductive busbars (copper or aluminum busbars) from the influence of the external environment, while ensuring electrical safety.

[0003] However, the existing busbar trunking top plate and side plate are generally connected and fixed with bolts. However, when installing in some narrow places, workers will use tools such as wrenches and screwdrivers to install it, which is cumbersome and very inconvenient for disassembly and maintenance. At the same time, the busbar trunking installed outdoors needs to be ventilated and cooled for internal wiring, which makes the waterproofing of the busbar trunking top plate not very good, thus limiting the performance of the busbar trunking.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of the existing waterproof and heat-dissipating top plate of the separate conductive busbar trunking. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof heat dissipation cover for a split-type busbar trunking, in order to solve the problems mentioned in the background art, such as inconvenience in disassembly and maintenance, and poor waterproofing capabilities, which limit the performance of the busbar trunking. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof heat dissipation cover for a split-type busbar trunking, comprising a side plate, a top plate installed at the upper and lower ends of the side plate, fixing blocks installed at the front and rear ends of the top of the top plate, mounting blocks fixedly connected to the bottom of both ends of the side plate, the top of the mounting blocks passing through the side plate and extending into the interior of the fixing blocks, a connecting mechanism installed inside the fixing blocks, and a ventilation and drainage mechanism installed at the center of the top of the top plate.

[0007] The connecting mechanism includes a locking block that limits sliding within a groove in the fixed block. There are two sets of locking blocks, which are symmetrically distributed on both sides of the mounting block. A first spring is fixedly connected to the end of the locking block away from the mounting block. The end of the first spring away from the locking block is fixedly connected to the inner wall of the limiting groove. A first limiting tooth is provided on the locking block at one end corresponding to the mounting block. An abutment rod is fixedly connected to one side of the rear end of the locking block. The abutment rod extends into the rear cavity inside the fixed block. An abutment block is provided in the middle area of ​​the end of the abutment rod located in the rear cavity. A fixed block extends from the top of the abutment block and is fixedly connected to a pull plate. A second spring is sleeved on the outer surface of the abutment block.

[0008] Preferably, the ventilation and drainage mechanism includes a baffle plate, which slides within a limiting groove in the middle area of ​​the top of the top plate. A ventilation slot is provided inside the baffle plate at the top of the top plate. A first drainage slot is vertically fixedly connected to the left and right sides of the top of the top plate on the baffle plate. A second drainage slot is horizontally fixedly connected to the top of the top plate at the front and rear sides of the baffle plate. A third drainage slot is horizontally fixedly connected to both ends of the top of the top plate near the fixing block. Sealing components are provided on both sides of the baffle plate.

[0009] Preferably, the sealing assembly includes a housing, which is fixedly connected to the top of the top plate on both sides of the baffle. A spur gear is rotatably connected to the top of the housing, and a rack is meshed with the tooth surfaces on both sides of the spur gear. A push rod is fixedly connected to one end of the rack away from the other end. The push rod extends out of the housing and is fixedly connected to the side opposite to the pull plate. A bevel gear assembly is rotatably connected to the bottom of the spur gear via a bearing. The bevel gear assembly extends into a limiting groove below the baffle and is fixedly connected to a rotating rod. A groove is provided at the bottom of the baffle, and the rotating rod slides within the groove. A guide rod is provided on one side of the top of the rotating rod, and a guide groove is provided on the inner wall of the groove corresponding to the guide rod.

[0010] Preferably, the top two sides of the mounting block are provided with second limiting teeth corresponding to the first limiting teeth, and the teeth of the first limiting teeth and the second limiting teeth are opposite in direction.

[0011] Preferably, the abutment rod has an "L" shaped structure, and the abutment block has an isosceles trapezoidal cross-section.

[0012] Preferably, the top periphery of the shield is provided with a sloping structure, and a plurality of ventilation holes are evenly opened on the middle surface of the periphery of the shield.

[0013] Preferably, the first, second, and third diversion channels are interconnected and configured as a flow guiding structure with a high center and low ends. The third diversion channel has a "U" shaped structure, and drainage holes are provided at both ends of the third diversion channel on both sides of the top plate.

[0014] Preferably, the guide rod slides within the guide groove, and the guide groove is configured as a spiral structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention comprises an installation block, a locking block, a first spring, a first limiting tooth, and a second limiting tooth. By inserting the installation block into the fixing block, the first limiting tooth on the locking block engages with the tooth surface of the second limiting tooth on the top of the installation block. Pressing the fixing block further secures the top plate and side plate, simplifying their installation. Simultaneously, the elasticity of the first spring maintains close contact between the tooth surfaces of the first and second limiting teeth. The two rows of first and second limiting teeth increase the meshing area, effectively enhancing shear resistance. Furthermore, the invention includes an abutment rod, an abutment block, and a pulling plate. Pulling the pulling plate moves the abutment block, which in turn moves the locking block to both sides, disengaging the first limiting tooth from the second limiting tooth and unlocking the top plate and side plate. This solves the problem of inconvenient disassembly of the top and side plates.

[0017] This invention comprises a baffle plate, a first drainage channel, a second drainage channel, a third drainage channel, a spur gear, a rack, a push rod, a bevel gear assembly, a rotating rod, a guide rod, and a guide groove. Ventilation holes on the baffle plate dissipate heat from the internal wiring. Simultaneously, the first, second, and third drainage channels drain water from the top of the top plate, improving its waterproof performance. During disassembly, pulling a pull plate moves the baffle plate, which in turn moves a push rod that drives a gear to rotate. This rotation of the gear drives the bevel gear assembly, which in turn drives the rotating rod. Together with the guide rod and guide groove, the baffle plate moves downwards until the bottom of its shielding portion contacts the top of the first and second drainage channels, sealing the interior of the baffle plate and effectively preventing water from entering the busbar trunking during disassembly, thus improving the waterproof capability of the top plate.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 The present invention provides a technical solution: a waterproof heat dissipation cover for a split-type busbar trunking, including a side plate 1, a top plate 2 installed at the upper and lower ends of the side plate 1, a fixing block 3 installed at the front and rear ends of the top of the top plate 2, an installation block 4 fixedly connected to the bottom of both ends of the side plate 1, the top of the installation block 4 passing through the side plate 1 and extending into the interior of the fixing block 3, a connecting mechanism installed inside the fixing block 3, and a ventilation and drainage mechanism installed at the center of the top of the top plate 2.

[0031] The connecting mechanism includes a locking block 51 that slides within a groove in the fixed block 3. There are two sets of locking blocks 51, symmetrically distributed on both sides of the mounting block 4. A first spring 52 is fixedly connected to the end of each locking block 51 away from the mounting block 4. The end of the first spring 52 away from the locking block 51 is fixedly connected to the inner wall of the limiting groove. A first limiting tooth 53 is provided on one end of the locking block 51 corresponding to the mounting block 4. Second limiting teeth 7 are provided on both sides of the top of the mounting block 4 corresponding to the first limiting tooth 53. The teeth of the first limiting tooth 53 and the second limiting tooth 7 have opposite directions. An abutment rod 54 is fixedly connected to one side of the rear end of the locking block 51. The abutment rod 54 extends into the rear cavity inside the fixed block 3. A middle area of ​​one end of the abutment rod 54 within the rear cavity is provided with... The abutment block 55 and the abutment rod 54 are in an "L" shape. The cross section of the abutment block 55 is set as an isosceles trapezoid. The top of the abutment block 55 extends into a fixing block 3 and is fixedly connected to a pull plate 56. The outer surface of the abutment block 55 is fitted with a second spring 57. The insertion hole at the bottom of the top plate 2 is aligned with the top of the fixing blocks 3 at both ends of the side plate 1 and pressed down to insert the fixing block 3 into the interior of the fixing block 3. At this time, the second limiting tooth 7 at the top of the fixing block 3 will abut against the first limiting tooth 53 on the locking block 51 and move to both sides. When the side plate 1 and the top plate 2 are tightly connected, the pressing stops. At this time, the first spring 52 pushes the locking block 51 to move under the elastic action, so that the tooth surfaces of the first limiting tooth 53 and the second limiting tooth 7 mesh with each other, realizing the fixed installation between the side plate 1 and the top plate 2.

[0032] In one embodiment of the present invention, the ventilation and drainage mechanism includes a baffle plate 61, which slides within a limiting groove in the middle region of the top of the top plate 2. A ventilation groove is formed inside the baffle plate 61 at the top of the top plate 2. An inclined structure is provided on the outer periphery of the top of the baffle plate 61. A plurality of ventilation holes are evenly distributed on the middle surface of the outer periphery of the baffle plate 61. A first drainage groove 62 is vertically fixedly connected to the left and right sides of the top of the top plate 2. A second drainage groove 63 is horizontally fixedly connected to the front and rear sides of the baffle plate 61 at the top of the top of the top plate 2. The first drainage groove 62, the second drainage groove 63, and the third drainage groove 64 are interconnected and configured as a guide structure that is high in the middle and low at both ends. The third drainage groove 64 has a "U"-shaped structure, and drainage holes are formed at both ends of the third drainage groove 64 on both sides of the top plate 2. The top ends of the top plate 2 are close to... A third drainage channel 64 is horizontally fixedly connected at the fixing block 3. Sealing components are provided on both sides of the baffle plate 61. The ventilation holes opened on the middle surface of the outer perimeter of the baffle plate 61 dissipate heat from the internal circuit. When it rains, rainwater will fall into the first drainage channel 62, the second drainage channel 63 and the third drainage channel 64 along the inclined surface set on the top perimeter of the baffle plate 61. Since the first drainage channel 62, the second drainage channel 63 and the third drainage channel 64 are flow guiding structures that are high in the middle and low at both ends and are interconnected, the rainwater will pass through the first drainage channel 62, the second drainage channel 63 and the third drainage channel 64 in sequence and be discharged from the drainage holes opened on both sides of the top plate 2. At the same time, part of the heat inside the busbar trunking will be transferred to the surface of the first drainage channel 62, the second drainage channel 63 and the third drainage channel 64 and dissipate heat through their surfaces, thereby improving the heat dissipation performance.

[0033] In one embodiment of the present invention, the sealing assembly includes a housing 651, which is fixedly connected to the top of the top plate 2 on both sides of the baffle plate 61. A spur gear 652 is rotatably connected to the top of the housing 651. A rack 653 is meshed with the tooth surfaces on both sides of the spur gear 652. A push rod 654 is fixedly connected to the opposite end of the rack 653. The push rod 654 extends out of the housing 651 and is fixedly connected to the side opposite to the pull plate 56. A bevel gear set 655 is rotatably connected to the bottom of the spur gear 652 via a bearing. The bevel gear assembly 655 extends into the limiting groove below the baffle plate 61 and is fixedly connected to a rotating rod 656. A groove is provided at the bottom of the baffle plate 61, and the rotating rod 656 slides within the groove. A guide rod 657 is provided on one side of the top of the rotating rod 656, and a guide groove 658 is provided on the inner wall of the groove corresponding to the guide rod 657. The guide rod 657 slides within the guide groove 658, which is a spiral structure. Pulling the pulling plate 56 causes the contact block 55 to move inward towards the top plate 2, contacting the contact rod 55. 4. Move to both ends, causing the first limiting tooth 53 to disengage from the second limiting tooth 7. Pulling the pulling plate 56 simultaneously moves the push rod 654. The movement of the push rod 654 causes the sprocket 652 inside the housing 651 to rotate. The rotation of the sprocket 652 causes the rack 653 on the other side to move, which in turn moves the pulling plate 56 on the fixing block 3 at the other end of the top plate 2, causing the fixing blocks 3 at both ends of the top plate 2 to unlock simultaneously. At this time, pull the top plate 2 upward to disassemble it. The rotation of the sprocket 652 simultaneously causes the rack 653 inside the housing 651 to move. The bevel gear assembly 655 at the bottom of the part rotates, which drives the rotating rod 656 in the limiting groove below the baffle plate 61 to rotate. The rotating rod 656 drives the guide rod 657 to rotate in the spiral guide groove 658 inside the baffle plate 61, thereby driving the baffle plate 61 to move downward until the bottom of the baffle plate 61 contacts the top of the first drainage groove 62 and the second drainage groove 63, so that the inside of the baffle plate 61 is sealed, preventing some of the water accumulated at the top of the top plate 2 from entering the busbar groove during disassembly.

[0034] Working principle: When using the waterproof heat dissipation top plate 2 of the conductive busbar split type busbar trunking, the side plate 1 and the top plate 2 need to be installed first. Align the insertion hole at the bottom of the top plate 2 with the top of the fixing blocks 3 at both ends of the side plate 1 and press down to insert the fixing blocks 3 into the interior of the fixing blocks 3. At this time, the second limiting tooth 7 at the top of the fixing block 3 will abut against the first limiting tooth 53 on the locking block 51 and move to both sides. When the side plate 1 and the top plate 2 are tightly connected, stop pressing. At this time, the first spring 52 pushes the locking block 51 to move under the elastic action, so that the tooth surfaces of the first limiting tooth 53 and the second limiting tooth 7 mesh with each other, realizing the fixed installation between the side plate 1 and the top plate 2.

[0035] When the busbar trunking is used outdoors, the ventilation holes on the central surface of the shield 61 dissipate heat from the internal wiring. When it rains, rainwater falls into the first drainage channel 62, the second drainage channel 63, and the third drainage channel 64 along the sloping surface on the top periphery of the shield 61. Since the first drainage channel 62, the second drainage channel 63, and the third drainage channel 64 are flow-guiding structures that are high in the middle and low at both ends and are interconnected, rainwater will pass through the first drainage channel 62, the second drainage channel 63, and the third drainage channel 64 in sequence and be discharged from the drainage holes on both sides of the top plate 2. At the same time, some of the heat inside the busbar trunking will be transferred to the surface of the first drainage channel 62, the second drainage channel 63, and the third drainage channel 64 and dissipate heat through their surfaces, thus improving the heat dissipation performance.

[0036] When maintenance is required inside the busbar trunking, pulling the pull plate 56 moves the contact block 55 inward toward the top plate 2, causing the contact rod 54 to move to both ends, disengaging the first limiting tooth 53 from the second limiting tooth 7. Simultaneously, pulling the pull plate 56 moves the push rod 654, which in turn rotates the sprocket 652 inside the housing 651. This rotation of the sprocket 652 moves the rack 653 on the other side, which in turn moves the pull plate 56 on the fixing block 3 at the other end of the top plate 2, unlocking the fixing blocks 3 at both ends of the top plate 2. At this point, pulling the top plate 2 upwards... During disassembly, the rotation of the spur gear 652 drives the bevel gear assembly 655 at the bottom of the housing 651 to rotate. The rotation of the bevel gear assembly 655 drives the rotating rod 656 in the limiting groove below the baffle plate 61 to rotate. The rotation of the rotating rod 656 drives the guide rod 657 to rotate in the spiral guide groove 658 inside the baffle plate 61, thereby driving the baffle plate 61 to move downward until the bottom of the baffle plate 61 contacts the top of the first drainage groove 62 and the second drainage groove 63, so that the inside of the baffle plate 61 is sealed, preventing some of the water accumulated at the top of the top plate 2 from entering the busbar groove during disassembly.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
