Description

Technical Field

[0001] The present invention relates to the technical field of bus ducts, and in particular to a waterproof heat dissipation cover plate of a conductive bar split type bus duct. Background Art

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

[0003] However, the existing bus duct top plate and bus duct side plates are generally connected and fixed by bolts. However, when installing in some narrow places, workers will use tools such as wrenches and screwdrivers for installation, which is cumbersome to install and very inconvenient to disassemble and repair. At the same time, the bus duct installed outdoors needs to ventilate and dissipate heat for the internal lines, which makes the waterproof ability of the bus duct top plate not very good, thereby limiting the performance of the bus duct.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-10 The present invention provides a technical solution: a waterproof heat dissipation cover plate for a conductive bar split bus duct, comprising a side panel 1, a top panel 2 installed at the upper and lower ends of the side panel 1, fixed blocks 3 installed at the front and rear ends of the top of the top panel 2, mounting blocks 4 fixedly connected to the bottom of both ends of the side panel 1, the top of the mounting block 4 passes through the side panel 1 and extends to the inside of the fixed block 3, a connecting mechanism is installed inside the fixed block 3, and a ventilation and drainage mechanism is installed at the center of the top of the top panel 2.

[0021] The connecting mechanism includes a locking block 51 that slides within the internal sliding groove of the fixed block 3. The locking blocks 51 are divided into two groups, and the two groups of locking blocks 51 are symmetrically distributed on both sides of the mounting block 4. The end of the locking block 51 away from the mounting block 4 is fixedly connected to the first spring 52, and the end of the first spring 52 away from the locking block 51 is fixedly connected to the inner wall of the limiting sliding groove. The locking block 51 is provided with a first limiting tooth 53 at one end corresponding to the mounting block 4, and second limiting teeth 7 are provided on both sides of the top of the mounting block 4 corresponding to the first limiting teeth 53. The tooth directions of the first limiting teeth 53 and the second limiting teeth 7 are opposite, and a resistance rod 54 is fixedly connected to one side of the rear end of the locking block 51. The resistance rod 54 extends to the rear side chamber inside the fixed block 3, and the middle area of ​​the resistance rod 54 at one end of the rear chamber is provided with The interference block 55 and the interference rod 54 are in an "L"-shaped structure. The cross-section of the interference block 55 is set to an isosceles trapezoidal structure. The fixing block 3 extends from the top of the interference block 55 and is fixedly connected to a pulling plate 56. The outer surface of the interference block 55 is sleeved with a second spring 57. The socket 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 downward to insert the fixing block 3 into the inside of the fixing block 3. At this time, the second limiting tooth 7 on the top of the fixing block 3 will interfere with 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 tight, the pressing is stopped. 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 engage with each other, thereby realizing the fixed installation between the side plate 1 and the top plate 2.

[0022] As an embodiment of the present invention, the ventilation and drainage mechanism includes a baffle plate 61, which slides in a limiting slide groove opened in the middle area of ​​the top of the top plate 2, and a ventilation groove is opened inside the baffle plate 61 at the top of the top plate 2. A slope structure is set on the periphery of the top of the baffle plate 61, and a number of ventilation holes are evenly opened on the middle surface of the periphery of the baffle plate 61. The top of the top plate 2 is located on the left and right sides of the baffle plate 61 and is vertically fixedly connected with a first drainage groove 62, and the top of the top plate 2 is located on the front and rear sides of the baffle plate 61 and is horizontally fixedly connected with a second drainage groove 63. The first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 are interconnected and are arranged to be a guide structure with a high middle part and low two ends. The third drainage groove 64 is a "U"-shaped structure, and the two ends of the third drainage groove 64 are located on both sides of the top plate 2 and have drainage holes. The two ends of the top of the top plate 2 are close to A third drainage groove 64 is fixedly connected horizontally at the fixed block 3, and sealing components are provided on both sides of the baffle plate 61. The internal circuit is cooled by ventilation holes opened on the outer middle surface of the baffle plate 61. When it rains, rainwater will fall into the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 along the inclined surface set on the top periphery of the baffle plate 61. Since the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 are diversion structures with a high middle part and low two ends, and are interconnected, rainwater will pass through the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 in turn, 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 bus duct will be transferred to the surface of the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64, and dissipated through their surface, thereby improving the heat dissipation performance.

[0023] As an embodiment of the present invention, the sealing assembly includes a shell 651, which is fixedly connected to the top of the top plate 2 and located on both sides of the shielding plate 61. The top of the shell 651 is rotatably connected to a circular gear 652. The tooth surfaces on both sides of the circular gear 652 are meshed and connected to a rack 653. The end away from the rack 653 is fixedly connected to a push rod 654. The push rod 654 extends out of the shell 651 and is fixedly connected to the side opposite to the pull plate 56. The circular gear 652 is rotatably connected to a bevel gear set 655 through a bearing. The bevel gear group 655 extends to the limiting slide groove below the shielding plate 61 and is fixedly connected to the rotating rod 656. A slide groove is provided at the bottom of the shielding plate 61. The rotating rod 656 slides in the limited position in the slide groove. A guide rod 657 is provided on one side of the top of the rotating rod 656. A guide groove 658 is provided on the inner wall of the slide groove corresponding to the guide rod 657. The guide rod 657 slides in the guide groove 658. The guide groove 658 is set to a spiral structure. Pulling the pulling plate 56 drives the interference block 55 to move toward the inside of the top plate 2 and interferes with the interference rod 5 4 moves to both ends, so that the first limiting tooth 53 disengages from the second limiting tooth 7, pulling the pulling plate 56 and driving the pushing rod 654 to move. The movement of the pushing rod 654 drives the circular gear 652 inside the shell 651 to rotate. The rotation of the circular gear 652 drives the rack 653 on the other side to move, thereby driving the pulling plate 56 on the fixing block 3 at the other end of the top plate 2 to move, so that the fixing blocks 3 at both ends of the top plate 2 are unlocked at the same time. At this time, the top plate 2 is pulled upward for disassembly, and the circular gear 652 rotates while driving the rack 653 inside the shell 651. The bevel gear group 655 at the bottom end rotates, and the bevel gear group 655 rotates to drive the rotating rod 656 in the limiting slide groove below the baffle plate 61 to rotate. The rotating rod 656 rotates to drive 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 shielding part 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 in a sealed state, preventing part of the accumulated water on the top of the top plate 2 from entering the bus duct during disassembly.

[0024] Working principle: When using the waterproof heat dissipation top plate 2 of the conductive bar split bus duct, you first need to install the side panel 1 and the top panel 2, align the socket at the bottom of the top panel 2 with the top of the fixing blocks 3 at both ends of the side panel 1 and press down to insert the fixing blocks 3 into the inside of the fixing blocks 3. At this time, the second limiting teeth 7 on the top of the fixing blocks 3 will conflict with the first limiting teeth 53 on the locking block 51 and move to both sides. When the side panel 1 and the top panel 2 are tight, 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 teeth 53 and the second limiting teeth 7 engage with each other, thereby achieving fixed installation between the side panel 1 and the top panel 2.

[0025] When the bus duct is used outdoors, the internal circuits are cooled through the ventilation holes opened on the middle surface of the outer periphery of the baffle 61. When it rains, rainwater will fall into the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 along the inclined surface set on the outer periphery of the top of the baffle 61. Since the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 are diversion structures with a high middle part and low ends, and are interconnected, rainwater will pass through the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64 in turn, 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 bus duct will be transferred to the surface of the first drainage groove 62, the second drainage groove 63 and the third drainage groove 64, and dissipate heat through their surface, thereby improving the heat dissipation performance.

[0026] When it is necessary to inspect the inside of the bus duct, the pulling plate 56 is pulled to drive the interference block 55 to move toward the inside of the top plate 2, and the interference rod 54 moves to both ends, so that the first limit tooth 53 disengages from the second limit tooth 7. The pulling plate 56 is pulled and the push rod 654 is moved. The movement of the push rod 654 drives the circular gear 652 inside the shell 651 to rotate. The rotation of the circular gear 652 drives the rack 653 on the other side to move, thereby driving the pulling plate 56 on the fixed block 3 at the other end of the top plate 2 to move, so that the fixed blocks 3 at both ends of the top plate 2 are unlocked at the same time. At this time, the top plate 2 is pulled upward for During disassembly, the circular gear 652 rotates and drives the bevel gear group 655 at the bottom end of the shell 651 to rotate. The rotation of the bevel gear group 655 drives the rotating rod 656 in the limiting slide 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 shielding part 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 in a sealed state, preventing part of the accumulated water on the top of the top plate 2 from entering the bus duct during disassembly.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
