Description

Technical Field

[0001] The invention relates to the technical field of bus ducts, and in particular to a bus duct protection device. Background Art

[0002] Bus duct is a common power structure. It is a closed metal device mainly composed of copper and aluminum busbars. Its main function is 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 and has strong conductive properties.

[0003] The external protection device of the existing bus duct is relatively simple, and cannot mitigate the damage caused to the bus duct by external factors in daily use, causing the bus duct to shake under the action of external force, which may cause the bus duct joint docking area to fall off or even be damaged, causing the bus duct to fail to work normally and affecting people's life use. Summary of the invention

[0004] The object of the present invention is to provide a busbar protection device around a slot to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A busbar protection device around a slot, comprising: a busbar slot body, a shell is arranged outside the busbar slot body, a heat dissipation strip is arranged on the surface of the shell, the shell extends to the interfaces at both ends of the busbar slot body, and is provided with a sealing component, the sealing component is composed of a fixing plate and a sealing plate, the fixing plate is connected to the shell, the sealing plate is arranged between the two fixing plates, and a micro air pump is arranged inside the busbar slot body;

[0007] The staff connected the interfaces at both ends of the bus duct body with other joints, and then wrapped the docking area with the fixed plate and the sealed plate, thereby achieving the sealing of the docking area. When the heat inside the bus duct body rises, the controller controls the micro air pump to start, and the micro air pump drives the flow of external air. The external air is transported to the inside of the bus duct body through the outer casing, thereby achieving heat exchange treatment, thereby reducing the problems inside the bus duct body and improving the efficiency of heat dissipation.

[0008] Preferably, movable frames are symmetrically arranged on both sides of the bus trough body, and a plurality of deflection plates are arranged in the movable frames. The plurality of deflection plates are equidistantly arranged along the sides of the movable frames. A No. 1 micro motor is arranged in the outer shell, and the driving shaft of the No. 1 micro motor passes through the bus trough body and is connected to the rotating shaft of the deflection plate. The deflection plate is rotatably connected to the movable frame, and a plurality of air outlets are arranged on one side of the bus trough body close to the interface of the bus trough body.

[0009] Preferably, one end of the shell close to the fixed plate is inclined toward a side away from the fixed plate, the distance between the shell and the fixed plate is greater than the distance between the shell and the bus duct body, and a protrusion is provided on one side of the shell close to the bus duct body.

[0010] Preferably, the sealed plate is provided with a rotating opening, the inner wall of the rotating opening is provided with a rotating groove, a rotating body is provided in the rotating opening, and the rotating body is rotatably connected to the rotating opening.

[0011] Preferably, the rotating body is composed of a central axis, a rotating ring and a plurality of rotating plates, the rotating ring is rotatably connected to the rotating groove, the axis of the central axis coincides with the axis of the rotating opening, a plurality of rotating plates are arranged around the axis of the central axis, the rotating plate is located between the central axis and the rotating ring, a No. 2 micro motor is arranged in the rotating ring, and the driving shaft of the No. 2 micro motor is connected to the transmission shaft of the rotating plate;

[0012] When the temperature inside the bus duct body rises, the controller first controls the No. 1 micro motor to start, and the driving shaft of the No. 1 micro motor drives the rotating shaft of the deflection plate to rotate, so that the deflection plate forms an angle with the axis of the moving frame, and then the space between the shell and the bus duct body is connected with the inside of the bus duct body, and the outside air then flows through the space between the shell and the fixed plate to the space between the shell and the bus duct body. Since the distance between the shell and the fixed plate is greater than the distance between the shell and the bus duct body, and a protrusion is provided on the side of the shell close to the bus duct body, the outside air quickly flows to the bus duct body, and the outside air flows from the gap between two adjacent deflection plates to the inside of the bus duct body;

[0013] Then, the air inside the bus duct body flows toward the air outlet, so that the air flows toward the docking area. At the same time, the controller controls the No. 2 micro motor to start, and the driving shaft of the No. 2 micro motor drives the transmission shaft of the rotating plate to rotate, so that several rotating plates rotate around the axis of the transmission shaft, and then the docking area is connected with the outside world. The air is then output to the outside world from the docking area through the gap between two adjacent rotating plates, and then the air flows through the interior of the bus duct body and the docking area in turn, and then the air drives the heat flowing through the area together, thereby improving the quality of heat dissipation. When the air flows through the rotating plate, the air will push the rotating plate to generate a rotational force during the movement of the air, and then the rotating plate drives the rotating ring and the central axis to rotate. In the process of the rotating plate rotating around the axis of the central axis, the air in the docking area is quickly output to the outside world from the docking area, thereby improving the efficiency of heat dissipation.

[0014] If a fire source appears inside the bus duct body, the controller will control the No. 2 micro motor to reverse, thereby resetting several rotating plates, so that the rotating plates will block the rotating ports, and the fixed plates and the sealed plates will block the docking area. The micro air pump will reversely pump air to extract the gas in the bus duct body to the outside, thereby reducing the oxygen content in the bus duct body. Subsequently, the No. 1 micro motor will reverse under the action of the controller, so that the deflection plate will block the moving frame, thereby forming a closed space in the bus duct body, so that the fire source cannot burn for too long in the space with low oxygen content, thereby reducing the damage caused to the bus duct by the fire source.

[0015] Preferably, a centering piece is provided at the bottom of the shell, the centering piece is in a symmetrical triangular shape, and a depression is provided at the bottom of the centering piece.

[0016] Preferably, a moving rod is provided at the bottom of the bus duct body, one end of the moving rod is rotatably connected to the bus duct body through a bearing, the other end of the moving rod is connected to the bus duct body through a tension spring, and a center column is provided in the middle of the moving rod.

[0017] Preferably, the center return piece is slidably connected to the center column.

[0018] When the shell is impacted and tilted, the shell drives the return plate to tilt during the tilting process, thereby causing the return plate to slide on the center column. Since there is a depression at the bottom of the return plate, no matter in which direction the return plate deflects, the return plate will squeeze the moving rod. The distance between the two symmetrically arranged corners of the return plate and the bus duct body is smaller than the distance between the depression of the return plate and the bus duct body, thereby causing the side of the moving rod away from the center column to move under the action of the return plate. At this time, the moving rod moves to the side close to the bus duct body. During the movement of the moving rod, one end of the moving rod is rotatably connected to the bus duct body through a bearing, and the other end of the moving rod is connected to the bus duct body through a tension spring, so that the tension spring applies a pulling force to the moving rod, and then the tension spring always drives the moving rod to reset, thereby causing the moving rod to react on the return plate, so that the depression at the bottom of the return plate contacts the center column, and then when the shell is in a tilted state, the bus duct body is in a balanced state under the action of the moving rod, thereby preventing the bus duct body from being affected by the tilt and the alignment area from falling off.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. If a fire source appears inside the bus duct body, the controller controls the No. 2 micro motor to reverse, thereby resetting several rotating plates, so that the rotating plates block the rotating ports, and the fixed plates and the sealed plates block the docking areas. The micro air pump reverses the air flow to extract the gas in the bus duct body to the outside, thereby reducing the oxygen content in the bus duct body. Subsequently, the No. 1 micro motor reverses under the action of the controller, so that the deflection plate blocks the moving frame, thereby forming a closed space in the bus duct body, so that the fire source cannot burn for too long in the space with low oxygen content, thereby reducing the damage caused to the bus duct by the fire source.

[0021] When the outer shell is impacted and tilted, the outer shell drives the return plate to tilt during the tilting process, thereby causing the return plate to slide on the center column. Since a depression is provided at the bottom of the return plate, the return plate will squeeze the moving rod no matter in which direction the return plate deflects. The distance between the two symmetrically arranged corners of the return plate and the bus duct body is smaller than the distance between the depression of the return plate and the bus duct body, thereby causing the side of the moving rod away from the center column to move under the action of the return plate. At this time, the moving rod moves to the side close to the bus duct body. During the movement of the moving rod, one end of the moving rod is rotatably connected to the bus duct body through a bearing, and the other end of the moving rod is connected to the bus duct body through a tension spring, so that the tension spring applies a pulling force to the moving rod, and then the tension spring always drives the moving rod to reset, thereby causing the moving rod to react on the return plate, so that the depression at the bottom of the return plate contacts the center column, and then when the outer shell is in a tilted state, the bus duct body is in a balanced state under the action of the moving rod, thereby preventing the bus duct body from being affected by the tilt and the alignment area from falling off.

The rotating ring 36 is rotatably connected to the rotating groove 331. The axis of the central axis 35 coincides with the axis of the rotating opening 33. The plurality of rotating plates 37 are arranged around the axis of the central axis 35. The rotating plate 37 is located between the central axis 35 and the rotating ring 36.

[0039] As a specific implementation of the present invention, the center return piece 22 is slidably connected to the center column 141 .

[0040] Working principle of the present invention:

[0041] When the temperature inside the bus duct body 1 rises, the controller first controls the No. 1 micro motor to start, and the driving shaft of the No. 1 micro motor drives the rotating shaft of the deflection plate 12 to rotate, so that the deflection plate 12 forms an angle with the axis of the moving frame 11, and then the space between the outer shell 2 and the bus duct body 1 is connected with the inside of the bus duct body 1, and the outside air then flows through the space between the outer shell 2 and the fixed plate 31 to the space between the outer shell 2 and the bus duct body 1. Since the distance between the outer shell 2 and the fixed plate 31 is greater than the distance between the outer shell 2 and the bus duct body 1, and a protrusion 21 is provided on the side of the outer shell 2 close to the bus duct body 1, the outside air quickly flows to the bus duct body 1, and the outside air flows from the gap between two adjacent deflection plates 12 to the inside of the bus duct body 1;

[0042] Then, the air inside the bus duct body 1 flows toward the air outlet 13, so that the air flows into the docking area. At the same time, the controller controls the No. 2 micro motor to start, and the driving shaft of the No. 2 micro motor drives the transmission shaft of the rotating plate 37 to rotate, so that several rotating plates 37 rotate around the axis of the transmission shaft, and then the docking area is connected with the outside world. The air is then output to the outside world from the docking area through the gap between two adjacent rotating plates 37, and then the air flows through the interior of the bus duct body 1 and the docking area in turn, and then the air drives the heat flowing through the area together, thereby improving the quality of heat dissipation. When the air flows through the rotating plate 37, the rotating plate 37 will be pushed to generate a rotational force during the movement of the air, and then the rotating plate 37 drives the rotating ring 36 and the central axis 35 to rotate. In the process of the rotating plate 37 rotating around the axis of the central axis 35, the air in the docking area is quickly output to the outside world from the docking area, thereby improving the efficiency of heat dissipation.

[0043] If a fire source appears inside the bus duct body 1, the controller controls the No. 2 micro motor to reverse, so that the plurality of rotating plates 37 are reset, so that the rotating plate 37 blocks the rotating port 33, so that the fixed plate 31 and the sealing plate 32 block the docking area, and the micro air pump reverses the air flow to extract the gas in the bus duct body 1 to the outside, so that the oxygen content in the bus duct body 1 decreases, and then the No. 1 micro motor reverses under the action of the controller, so that the deflection plate 12 blocks the moving frame 11, so that a closed space is formed in the bus duct body 1, so that the fire source cannot burn for too long in the space with low oxygen content, thereby reducing the damage caused by the fire source to the bus duct;

[0044] When the shell 2 is impacted and tilted, the shell 2 drives the return plate 22 to tilt during the tilting process, so that the return plate 22 slides on the center column 141. Since the bottom of the return plate 22 is provided with a depression, the return plate 22 will squeeze the moving rod 14 no matter in which direction the return plate 22 is deflected. The distance between the two symmetrically arranged corners of the return plate 22 and the bus duct body 1 is smaller than the distance between the depression of the return plate 22 and the bus duct body 1, so that the side of the moving rod 14 away from the center column 141 moves under the action of the return plate 22, and at this time, the moving rod 14 moves to the side close to the bus duct body 1 During the movement of the moving rod 14, since one end of the moving rod 14 is rotatably connected to the bus duct body 1 through a bearing, and the other end of the moving rod 14 is connected to the bus duct body 1 through a tension spring, the tension spring applies a pulling force to the moving rod 14, and the tension spring always drives the moving rod 14 to reset, so that the moving rod 14 reacts to the return plate 22, so that the depression at the bottom of the return plate 22 contacts the center column 141, and then when the outer shell 2 is in a tilted state, the bus duct body 1 is in a balanced state under the action of the moving rod 14, thereby preventing the bus duct body 1 from being affected by the tilt and causing the alignment area to fall off.
