Technical Field
[0001] The invention relates to the technical field of bus ducts, and in particular to an environmentally friendly bus duct with low noise operation and an assembly method thereof. Background Art
[0002] The low-noise environmentally friendly bus duct is a power transmission device with high protection level, waterproof, fireproof, anti-corrosion, explosion-proof and other characteristics. It is designed to reduce the impact on the environment and noise pollution while ensuring the power transmission efficiency, and improve the stability and service life of the equipment. As an efficient and safe power transmission equipment, bus duct is mainly used in large buildings, industrial plants and other places to connect substations and power equipment to achieve the distribution and transmission of electric energy. It has the characteristics of compact structure, large transmission capacity and convenient maintenance. The interior of the bus duct is usually composed of conductive copper bars and the outer layer is wrapped with insulating materials to ensure safe operation. When working, the bus duct transmits current through its internal conductors. At the same time, its design also takes into account heat dissipation and electromagnetic compatibility to reduce noise and improve system stability. During the installation and use of existing bus ducts, the bus ducts are usually fixed in a certain position using fixed parts so that the bus ducts can stably connect and transmit cables. However, some bus ducts are working in a relatively complex working environment. Various machines in the environment will generate more vibrations, which are then transmitted to the bus duct through sound waves in the air. Because the bus ducts generate the same frequency resonance, the fixed parts at the fixed positions of the bus ducts become loose, which can easily cause the bus duct to generate vibration noise. Therefore, in view of the above problems, an environmentally friendly bus duct with low noise operation and an assembly method thereof are proposed. Summary of the invention

[0006] As a further optimization of the present invention, the fixing plate is arranged between the right-angle bend and the shock-absorbing plate, the width of the fixing plate is the same as the width of the shock-absorbing plate, four through holes are opened on the inner side of the shock-absorbing plate, two films are evenly arranged in the through holes opened on the inner side of the shock-absorbing plate, and the cavity between the films is filled with harmless dye.
[0007] As a further optimization of the present invention, there are four evenly distributed cone thorns on the same side of the fixed plate, the cone thorns are arranged directly above the film, and the sharp ends of the cone thorns are facing the film, the maximum diameter of the cone thorns is smaller than the diameter of the film, and the cone thorns are arranged on the inner side of the first telescopic spring.
[0008] As a further optimization of the present invention, the cross-section of the rubber rod is elliptical, the rubber rod is arranged between the copper bars and between the copper bars and the right-angle bends, the rubber rod is tightly attached to the insulating sleeve and the right-angle bends respectively, and the two ends of the rubber rod are tightly attached to the fixing plate and the strip plate respectively.
[0009] As a further optimization of the present invention, the rotating shaft at the lower end of the rubber rod rotates on the inner side of the strip plate, the rubber rod, the rotating shaft and the square rod are on the same axial line, the cross-section of the square rod is rectangular, the height of the rotating shaft is the same as the thickness of the fixed plate, and the same group of rubber rods between the right-angle bends are on the same vertical plane.

[0011] As a further optimization of the present invention, two symmetrical fixing pins are arranged on the side of the knob close to the slat, and a number of evenly distributed pin holes are opened in the slat within the rotation range of the knob. The number of pin holes within the rotation range of the knob is twice the number of fixing pins, and the pin holes are all opened outside the rotation range of the square rod.
[0012] As a further optimization of the present invention, the strip plate and the fixed plate are parallel to each other, the strip plate and the fixed plate have the same length, two holes are symmetrically opened on the inner sides of the strip plate and the fixed plate, the strip plate is arranged within the horizontal range of the fixed plate, and the right-angle bend is connected together through the strip plate and the fixed plate.
[0013] As further optimized content of the present invention, wherein: S1: When installing and using the environmentally friendly bus duct, the side of the bus duct provided with the shock-absorbing and noise-reducing mechanism can be oriented toward the plane position to be fixed, so that the shock-absorbing plate of the shock-absorbing and noise-reducing mechanism is in close contact with the fixed plane position. At this time, the fixed plate in the shock-absorbing and noise-reducing mechanism is in close contact with the fixing ears of the right-angle bent piece through bolts, so that the shock-absorbing and noise-reducing mechanism can be placed between the fixed plane position and the bus duct by inserting the bolt spirally into the plane position to be fixed. When the bolt is gradually fixed in the fixed plane position, the right-angle bent piece exerts a thrust on the fixed plate. , so that the fixed plate drives the cone thorns fixedly connected thereto to approach the damping plate closely attached to the fixed plane position, and the fixed plate exerts a compressive force on the first telescopic spring between the fixed plate and the damping plate, until the cone thorns in the first telescopic spring pierce the film inside the damping plate, so that the harmless dye between the two films of the damping plate leaks out, so as to remind the operator that the control depth of the bolts has reached the requirement, and at this time, the environmentally friendly bus duct has a relatively stable performance and is fixed on a fixed plane position, thereby blocking the same-frequency resonance noise generated by the vibration of the external environment on the entire bus duct; S2: When using the environmentally friendly bus duct, the strips in the isolation and noise reduction mechanism are fixed together with the fixing ears of the right-angle bend by means of core-driving rivets. Then, according to the spacing between the copper bars in the bus duct, the knob in the isolation and noise reduction mechanism can be pulled upwards, so that the fixing pin fixedly connected to the knob is disengaged from the pin hole in the strip. At the same time, when the knob moves upwards, a compressive force is applied to the second telescopic spring at its upper end, so that the knob that can only move vertically on the square rod can make a circular motion, and the knob is controlled to make an axial motion. The knob can drive the elliptical rubber rod to rotate through the square rod, so that the rubber rod can be closely attached to the insulating sleeves on the outside of two adjacent copper bars or respectively closely attached to the right-angle bend and the insulating sleeves on the outside of its adjacent copper bars. When the rubber rod rotates, its fixedly connected rotating shaft rotates in the fixed plate, providing a stable support limit for the position of the rubber rod. Under the action of the rubber rod, the gaps between the copper bars and the right-angle bends are filled and limited, and the vibration noise of the copper bars caused by the influence of the external environment is effectively isolated and reduced. S3: After the position of the rubber rod is adjusted, the control of the knob can be released, so that the knob moves downward along the square rod under the restoring force of the second telescopic spring until the two fixing pins fixed to the knob are re-engaged into the pin holes of another group. At this time, the knob is tightly attached to the strip again, so that the fixed restriction of the position of the rubber rod after rotation can be achieved.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by providing a fixed plate, a cone spike, a first telescopic spring and a damping plate, the cone spike can compress and eventually pierce the film inside the damping plate through the action of the first telescopic spring, thereby leaking the harmless dye on both sides of the damping plate, reminding the operator that the bolts have been tightened to a suitable depth, and at the same time blocking the influence of external vibration on the bus duct, reducing the resonance noise generated by external environmental vibration and the bus duct; 2. In the present invention, by providing the strips, square rods, rubber rods, rotating shafts and knobs, the rubber rods can move between the copper bar and the right-angle bent piece through the control of the knobs to fill the gap and reduce the vibration and noise of the conductive copper bar caused by the influence of the electric force; 3. In the present invention, the knob is provided to allow the operator to control the position of the rubber rod by simply turning it, thereby adjusting the gap between the copper bars, and after the adjustment is completed, the position can be automatically fixed by the force of the second telescopic spring.

The width of the fixing plate 331 is the same as that of the shock absorbing plate 334. Four through holes are opened inside the shock absorbing plate 334. Two films 335 are evenly arranged in the through holes opened inside the shock absorbing plate 334.

The rubber rod 343 is in close contact with the insulating sleeve 4 and the right-angle bend 31 respectively, and the two ends of the rubber rod 343 are in close contact with the fixing plate 331 and the strip plate 341 respectively, so that the gap between the copper bars 5 or between the copper bars 5 and the right-angle bend 31 can be filled; As a technical solution for further implementation of this solution, the rotating shaft 344 at the lower end of the rubber rod 343 rotates inside the strip plate 341, the rubber rod 343, the rotating shaft 344 and the square rod 342 are on the same axis, the cross section of the square rod 342 is rectangular, the height of the rotating shaft 344 is the same as the thickness of the fixed plate 331, and the same group of rubber rods 343 between the right-angle bent pieces 31 are on the same vertical plane, which can ensure the stable rotation of the rubber rods 343; As a further technical solution of this solution, the second telescopic spring 346 is arranged outside the square rod 342, the second telescopic spring 346 is in close contact with the lower end of the limit plate 347, and the second telescopic spring 346 is arranged on the upper end of the knob 345, and the knob 345 is in close contact with the strip 341, so that the second telescopic spring 346 can control the knob 345 to reset. As a technical solution for further implementing the present invention, two symmetrical fixing pins 348 are arranged on the side of the knob 345 close to the strip 341, and a number of evenly distributed pin holes 349 are opened in the strip 341 within the rotation range of the knob 345. The number of the pin holes 349 within the rotation range of the knob 345 is twice the number of the fixing pins 348. The pin holes 349 are all opened outside the rotation range of the square rod 342, so as to fix and limit the position of the rubber rod 343 after rotation. As a technical solution for further implementing the present scheme, the strip 341 and the fixed plate 331 are parallel to each other, the strip 341 and the fixed plate 331 have the same length, two holes are symmetrically provided on the inner sides of the strip 341 and the fixed plate 331, the strip 341 is arranged within the horizontal range of the fixed plate 331, and the right-angle bend 31 is connected together through the strip 341 and the fixed plate 331, which can ensure that the shock-absorbing and noise reduction mechanism 33 and the isolation and noise reduction mechanism 34 are stably placed on the right-angle bend 31.
[0019] Workflow: S1: When installing and using the environmentally friendly bus duct, the bus duct can be provided with a side of the shock-absorbing and noise-reducing mechanism 33 facing the plane position to be fixed, so that the shock-absorbing plate 334 of the shock-absorbing and noise-reducing mechanism 33 is tightly attached to the fixed plane position. At this time, the fixed plate 331 in the shock-absorbing and noise-reducing mechanism 33 is tightly attached to the fixed ear 32 of the right-angle bend 31 through the bolt 6, so that the shock-absorbing and noise-reducing mechanism 33 can be placed between the fixed plane position and the bus duct by screwing the bolt 6 into the desired fixed plane position. When the bolt 6 is gradually fixed in the fixed plane position, the right-angle bend 31 exerts a thrust on the fixed plate 331, so that The fixing plate 331 drives the cone spikes 332 fixedly connected thereto to approach the damping plate 334 which is in close contact with the fixed plane position, and the fixing plate 331 exerts a compressive force on the first telescopic spring 333 between the fixing plate 331 and the damping plate 334, until the cone spikes 332 in the first telescopic spring 333 pierce the film 335 on the inner side of the damping plate 334, so that the harmless dye between the two films 335 of the damping plate 334 leaks out, so as to remind the operator that the control depth of the bolt 6 has reached the requirement, and at this time, the environmentally friendly bus duct has a relatively stable performance and is fixed on a fixed plane position, thereby blocking the same-frequency resonance noise generated by the vibration of the external environment on the entire bus duct; S2: When using the environmentally friendly bus duct, the strip plate 341 in the isolation and noise reduction mechanism 34 is fixed together with the fixing ear 32 of the right-angle bend 31 through the core rivet 7, and then the knob 345 in the isolation and noise reduction mechanism 34 can be pulled upward according to the spacing between the copper bars 5 in the bus duct, so that the fixing pin 348 fixedly connected to the knob 345 is disengaged from the pin hole 349 in the strip plate 341, and at the same time, when the knob 345 moves upward, a compressive force is applied to the second telescopic spring 346 at its upper end, so that the knob 345 that can only move vertically on the square rod 342 can make a circular motion, and the knob 345 is controlled to make an axial motion. The knob 345 can drive the elliptical rubber rod 343 to rotate through the square rod 342, so that the rubber rod 343 can be closely attached to the insulating sleeves 4 on the outside of two adjacent copper bars 5 or closely attached to the right-angle bent piece 31 and the insulating sleeves 4 on the outside of its adjacent copper bars 5. When the rubber rod 343 rotates, the rotating shaft 344 to which it is fixed rotates in the fixing plate 331, providing a stable support and restriction for the position of the rubber rod 343. Under the action of the rubber rod 343, the gaps between each copper bar 5 and the right-angle bent piece 31 are filled and restricted, effectively isolating and reducing the vibration noise of the copper bar 5 caused by the external environment. S3: After the position of the rubber rod 343 is adjusted, the control of the knob 345 can be released, so that the knob 345 moves downward along the square rod 342 under the restoring force of the second telescopic spring 346, until the two fixing pins 348 fixedly connected to the knob 345 are re-engaged into the pin holes 349 of another group, and the knob 345 is again tightly attached to the strip plate 341, so that the position of the rubber rod 343 after rotation can be fixed and restricted; The environment-friendly bus duct effectively reduces the resonance noise generated by the external environment vibration and the bus duct through the shock-absorbing and noise-reducing mechanism 33 and the isolation and noise-reducing mechanism 34, and reduces the vibration and noise generated by the conductive copper bus 5 due to the influence of electric power.

The low-noise, environmentally friendly bus duct according to claim 1, characterized in that: The strip plate (341) and the fixed plate (331) are parallel to each other, the strip plate (341) and the fixed plate (331) are of the same length, two holes are symmetrically provided on the inner sides of the strip plate (341) and the fixed plate (331), the strip plate (341) is arranged within the horizontal range of the fixed plate (331), and the right-angle bent piece (31) is connected together via the strip plate (341) and the fixed plate (331).
10. A low-noise, environmentally friendly bus duct assembly method according to any one of claims 1 to 9, characterized in that: S1: When installing and using the environmentally friendly bus duct, the side of the bus duct provided with the shock-absorbing and noise-reducing mechanism (33) can be oriented toward the plane position to be fixed, so that the shock-absorbing plate (334) of the shock-absorbing and noise-reducing mechanism (33) is in close contact with the fixed plane position. At this time, the fixing plate (331) in the shock-absorbing and noise-reducing mechanism (33) is in close contact with the fixing ear (32) of the right-angle bent piece (31) through the bolt (6). Thus, the bolt (6) can be spirally inserted into the plane position to be fixed, so that the shock-absorbing and noise-reducing mechanism (33) can be placed between the fixed plane position and the bus duct. When the bolt (6) is gradually fixed in the fixed plane position, the right-angle bent piece (31) exerts a thrust on the fixing plate (331), so that the fixing plate (331) is fixed. The plate (331) drives the cone spike (332) fixedly connected thereto to approach the damping plate (334) in close contact with the fixed plane position, and the fixed plate (331) exerts a compressive force on the first telescopic spring (333) between the plate (331) and the damping plate (334), until the cone spike (332) in the first telescopic spring (333) pierces the film (335) inside the damping plate (334), so that the harmless dye between the two films (335) of the damping plate (334) leaks out, so as to remind the operator that the control depth of the bolt (6) meets the requirement, and at this time, the environmentally friendly bus duct has a relatively stable performance and is fixed at a fixed plane position, thereby blocking the same-frequency resonance noise generated by the vibration of the external environment on the entire bus duct; S2: When the environmentally friendly bus duct is used, the strip plate (341) in the isolation and noise reduction mechanism (34) is fixed together with the fixing ear (32) of the right-angle bending piece (31) by means of the core rivet (7), and then the knob (345) in the isolation and noise reduction mechanism (34) can be pulled upward according to the spacing between the copper bars (5) in the bus duct, so that the fixing pin (348) fixedly connected to the knob (345) is separated from the pin hole (349) in the strip plate (341), and at the same time, when the knob (345) moves upward, a compressive force is applied to the second telescopic spring (346) at its upper end, so that the knob (345) that can only move vertically on the square rod (342) can make a circular motion, and the knob (345) can be controlled to make an axial motion. The knob (345) can drive the elliptical rubber rod (343) to rotate via the square rod (342), so that the rubber rod (343) can be closely attached to the insulating sleeves (4) on the outside of two adjacent copper bars (5) or closely attached to the right-angle bent piece (31) and the insulating sleeves (4) on the outside of the adjacent copper bars (5), and while the rubber rod (343) rotates, the rotating shaft (344) to which it is fixedly connected rotates in the fixing plate (331), providing stable support and restriction for the position of the rubber rod (343), so that under the action of the rubber rod (343), the gaps between the copper bars (5) and the right-angle bent piece (31) are filled and restricted, thereby effectively isolating and reducing the vibration noise generated by the copper bars (5) due to the influence of the external environment; S3: After the position of the rubber rod (343) is adjusted, the control of the rotating knob (345) can be released, so that the rotating knob (345) moves downward along the square rod (342) under the restoring force of the second telescopic spring (346) until the two fixing pins (348) fixedly connected to the rotating knob (345) are re-engaged into the other group of pin holes (349). At this time, the rotating knob (345) is again tightly attached to the strip plate (341), so that the fixed restriction of the position of the rubber rod (343) after rotation can be achieved.
