Technical Field

[0001] The present application relates to the technical field of bus ducts, and in particular to a safe and energy-saving bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Existing bus ducts are all installed in sections. After the ends of adjacent bus ducts are connected, they are wrapped and closed with two side plates, a cover plate and a top plate, and their two ends are fixed to the two bus ducts by multiple bolts.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the size of each plate can only be used to wrap and install the bus duct of the appropriate model size, and the applicability is low. Summary of the invention

[0005] In order to improve the applicability of the installation structure at the end connection of the bus duct to different models of bus ducts, the present application provides a safe and energy-saving bus duct.

[0006] The safe and energy-saving bus duct provided in this application adopts the following technical solutions:

[0007] A safe and energy-saving bus duct comprises a bus duct body, and protective boxes are sleeved on the ends of adjacent bus duct bodies, and the two ends of the protective boxes extend to different bus duct bodies respectively; the protective box comprises four bent plates, and the installation positions of the bent plates are located at the corners of the bus duct body, and the four bent plates form a ring shape and wrap the ends of the bus duct body; an insert plate is fixed on one end face of the bent plate, and a slot for inserting the insert plate on the adjacent bent plate is opened on the other end face; a fastening component for fixing the insert plate in the slot is provided between the insert plate and the bent plate into which it is inserted, and a reinforcement component for fixing the two is provided between each bent plate and the bus duct body.

[0008] By adopting the above technical scheme, the protection box can protect the connection between the bus duct bodies, and according to the size of the bus duct, the distance between adjacent bending plates can be adjusted to allow the plug-in plate to slide in the corresponding slot. After the protection box seals the connection of the bus duct body, the plug-in plate is fixed in the corresponding slot by the fastening component. At this time, the shape and size of the protection box are fixed, and the bending plate and the bus duct body are fixed by the reinforcement component to fix the protection box and the bus duct body, thereby improving the stability of the connection of the bus duct body. Finally, this installation structure can be applied to bus ducts of different sizes, which improves the applicability of the installation structure at the end connection of the bus duct to bus ducts of different models.

[0009] Optionally, flanges are fixed at the four corners of the bus duct body, and pits are formed between two adjacent flanges and the outer wall of the bus duct body.

[0010] By adopting the above technical solution, the arrangement of the flange and the pit can provide installation space for the fastening components and the reinforcement components on the one hand, and can improve the heat dissipation effect of the bus duct body on the other hand.

[0011] Optionally, the fastening assembly includes an extrusion block, an elastic member, and a pressure plate. A through hole is opened on the inner wall of the slot near the bus duct body, the extrusion block is slidably connected in the through hole, the elastic member is fixed on the side wall of the extrusion block facing the bus duct body, and the pressure plate is fixed on the side wall of the elastic member away from the extrusion block. When the elastic member is in a natural state, one end of the extrusion block is located inside the slot, and the extrusion block is inclined toward the side of the slot opening.

[0012] By adopting the above technical solution, when the plug-in board is inserted into the corresponding slot, the inclined surface of the extrusion block is squeezed, and the extrusion block squeezes the elastic member to compress it. The elastic member presses the pressure plate tightly against the outer wall of the bus duct body, and the elastic member presses the extrusion block tightly against the plug-in board, which not only fixes the plug-in board in the slot, but also improves the firmness between the protection box and the bus duct body.

[0013] Optionally, the end of the plug plate is arranged at an angle and is adapted to the inclined surface of the extrusion block.

[0014] By adopting the above technical solution, the convenience of squeezing the extrusion block by the plug board is improved, and the force applied when inserting the plug board into the slot is reduced.

[0015] Optionally, a first dovetail groove is opened on one side of the through hole, and a dovetail bar is fixed on one side of the extrusion block, and the dovetail bar is always located in the first dovetail groove; the friction between the dovetail bar and the first dovetail groove keeps the extrusion block in the through hole unchanged when no external force is applied.

[0016] By adopting the above technical solution, when the extrusion block is lifted or lowered in the through hole, the dovetail bar slides in the first dovetail groove, thereby improving the lifting stability of the extrusion block. In addition, due to the friction setting between the dovetail bar and the first dovetail groove, the extrusion block will not fall off from the through hole during transportation and installation of the bending plate, thereby improving the installation convenience of the protective box.

[0017] Optionally, the elastic member is a spring or a rubber block.

[0018] Optionally, the reinforcement assembly includes a screw, a slide plate, an elastic strip, and a reset member. The slide plate is slidably connected to the surface of the bending plate located in the pit, the elastic strip is fixed to the end of the slide plate facing the flange and is used to tighten the flange, the screw is threadedly connected to the bending plate and inserted into the pit, and the end of the slide plate facing away from the elastic strip is an inclined surface for the screw to be squeezed; after the screw is separated from the slide plate, the reset member is used to drive the slide plate and the elastic strip to reset; when the elastic strip is in a natural state, the inclined surface of the slide plate is set opposite to the end of the screw.

[0019] By adopting the above technical solution, after the bending plate is placed on the bus duct body, the screw is screwed onto the bending plate, one end of the screw squeezes the inclined surface of the slide plate, the slide plate slides toward the flange, and the elastic strip is pressed against the flange. The extrusion movement of the screw on the slide plate can be adjusted according to the compression degree of the elastic strip. The operation is simple and the stability effect between the bending plate and the bus duct body is improved. After the screw is screwed out, the reset part drives the slide plate and the elastic part to reset, so as to facilitate the next installation.

[0020] Optionally, the end of the stud inserted into the pit is arranged in an arc shape.

[0021] By adopting the above technical solution, on the one hand, the sliding plate can be pushed more easily to slide, and on the other hand, the arc end of the stud can be pressed tightly against the outer wall of the bus duct body, which not only improves the firmness between the protection box and the bus duct body, but also reduces the wear between the screw and the outer wall of the bus duct body.

[0022] Optionally, a dovetail block is fixed on the surface of the slide plate facing the bending plate, and a second dovetail groove for the dovetail block to slide in is provided on the bending plate.

[0023] By adopting the above technical solution, when the slide plate slides, the dovetail block slides in the second dovetail groove, thereby improving the sliding stability of the slide plate.

[0024] Optionally, the reset member is a spring, which is located in the second dovetail groove and fixed to the inner wall of the second dovetail groove, and the other end of the reset member is fixed to the dovetail block.

[0025] By adopting the above technical solution, when the slide plate slides, the dovetail block drives the reset member to extend and retract; after the screw rod is separated from the slide plate, the reset member drives the dovetail block and the slide plate to reset, which has a simple structure and good effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. According to the size of the bus duct, the distance between adjacent bent plates can be adjusted so that the plug-in plate can slide in the corresponding slot, the plug-in plate can be fixed in the corresponding slot by the fastening component, and the bent plate and the bus duct body can be fixed by the reinforcement component, thereby improving the applicability of the installation structure at the end connection of the bus duct to different models of bus ducts;

[0028] 2. The plug-in plate squeezes the inclined surface of the squeezing block, and the squeezing block squeezes the elastic member to compress it. The elastic member presses the pressing plate tightly against the outer wall of the bus duct body, and the elastic member presses the squeezing block tightly against the plug-in plate, which not only fixes the plug-in plate in the slot, but also improves the firmness between the protection box and the bus duct body;

[0029] 3. Due to the friction between the dovetail strip and the first dovetail groove, the extrusion block will not fall off from the through hole during transportation and installation of the bent plate, thereby improving the convenience of installation of the protection box;

The protection box 2 is divided into four bending plates 21 with 90° corners, and the position of each bending plate 21 is correspondingly installed at the flange 11. The four bending plates 21 form a ring and wrap the connection of the bus duct body 1; a plug-in plate 211 is fixed at one end of each bending plate 21, and a slot 212 for inserting the plug-in plate 211 on the adjacent bending plate 21 is opened on the other end surface; a fastening component 3 for fixing the plug-in plate 211 in the slot 212 is provided between the plug-in plate 211 and the bent plate 21 into which it is inserted, and a reinforcement component 4 for fixing the two is provided between each bending plate 21 and the bus duct body 1.

[0037] The flanges 11 at the corners of the bus duct body 1 are to improve the heat dissipation effect of the bus duct, and the pits 12 produced by them can provide convenient space for the installation structure in this application; when installing the protection box 2, the plug-in plates 211 and the slots 212 on the four bending plates 21 are plugged into each other until the four bending plates 21 are all fitted to the corresponding flanges 11.
