Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Embodiment 1, by Figures 1 to 3The present invention provides an environmentally friendly recyclable bus duct, comprising a bus duct body 1, the bus duct body 1 is composed of a shell 2, a plurality of combined conductive busbars 3, a cover plate 4, an adaptive fire extinguishing mechanism 5, an air inlet and heat dissipation component 6 and an exhaust component 7, the combined conductive busbar 3 is inserted and connected to the inside of the shell 2, the outer surface of the combined conductive busbar 3 is provided with an insulating layer 8, the cover plate 4 is connected to the top of the shell 2, the adaptive fire extinguishing mechanism 5 is inserted and connected to the top of the cover plate 4, the air inlet and heat dissipation component 6 is inserted and connected to one end of the top of the cover plate 4, and the exhaust component 7 is inserted and connected to one end of the top of the cover plate 4 away from the air inlet and heat dissipation component 6;

[0037] Embodiment 2, based on embodiment 1, Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 It is given that the combined conductive busbar 3 is composed of a first busbar 9, a second busbar 10 and an overheating automatic separation mechanism 11. The first busbar 9 is inserted and connected to one end inside the shell 2, and the second busbar 10 is inserted and connected to the other end inside the shell 2. The overheating automatic separation mechanism 11 is connected between the first busbar 9, the second busbar 10 and the shell 2. The overheating automatic separation mechanism 11 is composed of a limit support component 12, a first movable contact component 13, a second movable contact component 14 and a thermal deformation component 15. The limit support component 12 is fixedly connected to the bottom end inside the shell 2, one end of the second movable contact component 14 is sleeved on the limit support component 12 and is rotatably connected thereto, one end of the first movable contact component 13 is sleeved on the second movable contact component 14 and is slidably connected thereto, and the thermal deformation component 15 is fixedly connected between the first movable contact component 13, the second movable contact component 14 and the shell 2;

[0038] When the temperature of the first busbar 9 and the second busbar 10 is too high, the thermal deformation component 15 is deformed by the heat, and the first movable contact component 13 and the second movable contact component 14 are driven by the thermal deformation component 15 to rotate around the limit support component 12, so that the first movable contact component 13 and the second movable contact component 14 are separated from the first busbar 9 and the second busbar 10, thereby realizing automatic circuit breaking;

[0039] The first busbar 9 and the second busbar 10 are provided with a strip groove 16 matching the first movable contact assembly 13 and the second movable contact assembly 14 at one end close to the overheating automatic separation mechanism 11. The limit support assembly 12 is composed of a support column 17, a support beam 18 and a limit pressure roller 19. The support column 17 is fixedly connected to the shell 2, the support beam 18 is fixedly connected to the top of the support column 17, and the limit pressure roller 19 is rotatably connected to the other end of the bottom of the support beam 18 and is closely connected to the first movable contact assembly 13. The first movable contact assembly 13 is composed of a first conductive plate 20, a first conductive plug plate 21 and a semi-covered conductive sleeve 22. The first conductive plug plate 21 is fixedly connected to one end of the side of the first conductive plate 20 and matches the strip groove 16. The semi-covered conductive sleeve 22 is fixedly connected to the other end of the first conductive plate 20 and is sleeved on the second movable contact assembly 14. The second movable contact assembly 14 is composed of a second conductive plate 23, a second conductive plug plate 24 and a fully covered conductive sleeve 25. The second conductive plug plate 24 is fixedly connected to the first conductive plate 20. One end of the side of the second conductive plate 23 matches the strip groove 16, the fully covered conductive sleeve 25 is fixedly connected to the other end of the second conductive plate 23 and sleeved on the support column 17, the fully covered conductive sleeve 25 and the support column 17 are rotatably connected through a ceramic bearing 26, the semi-covered conductive sleeve 22 is sleeved on the fully covered conductive sleeve 25 and slidably connected thereto, the thermal deformation component 15 is composed of a thermal deformation metal plate 27, a jacket 28, a first connecting seat 29 and a second connecting sleeve 30, and the jacket 28 is sleeved on the thermal deformation metal plate 27 The heat-deformable metal plate 27 is located at the middle position of the outer surface and is fixedly connected to the shell 2. The first connection seat 29 and the second connection sleeve 30 are respectively fixedly connected to the two ends of the side of the heat-deformable metal plate 27. The first connection seat 29 and the second connection sleeve 30 are respectively fixedly connected to the first conductive plate 20 and the second conductive plug plate 24. The heat-deformable metal plate 27 is composed of a first metal plate 31 and a second metal plate 32. The second metal plate 32 is fixedly connected to the top of the first metal plate 31. The expansion coefficient of the first metal plate 31 is greater than the expansion coefficient of the second metal plate 32.

[0040] When the temperature of the heat-deformed metal plate 27 is too high, since the expansion coefficient of the first metal plate 31 is greater than the expansion coefficient of the second metal plate 32, the first metal plate 31 is greatly deformed at this time, and the first metal plate 31 is bent toward the square of the second metal plate 32 through the limiting effect of the second metal plate 32. At this time, the heat-deformed metal plate 27 drives the first connecting seat 29 and the second connecting sleeve 30 to move, and the first connecting seat 29 and the second connecting sleeve 30 respectively drive the first conductive plate 20 and the second conductive plate 23 to move, and the fully-enclosed conductive sleeve 25 rotates around the supporting column 17, and the ceramic bearing 26 can improve the mobility and play an insulating role at the same time. The semi-enclosed conductive sleeve 22 rotates around the outer surface of the fully-enclosed conductive sleeve 25, and the semi-enclosed conductive sleeve 22 rotates around the outer surface of the fully-enclosed conductive sleeve 25. The design of the electric sleeve 22 and the fully covered conductive sleeve 25 can improve the contact effect during normal operation, and thus improve the conductive effect. If the deformation of the heat-deformed metal plate 27 is not large, it means that the temperature at this time is within the normal range, and the first conductive plug plate 21 and the second conductive plug plate 24 are still in contact with the first busbar 9 and the second busbar 10, and normal conductivity is achieved at this time. When the temperature is abnormally high, the deformation of the heat-deformed metal plate 27 reaches the maximum. At this time, the first conductive plug plate 21 and the second conductive plug plate 24 are completely separated from the first busbar 9 and the second busbar 10, thereby achieving power failure. Through the design of the supporting beam 18 and the limiting pressure roller 19, the stability of the connection between the semi-covered conductive sleeve 22 and the fully covered conductive sleeve 25 can be improved to avoid detachment.

[0041] Embodiment 3, based on embodiment 1, Figures 2 to 4 It is shown that the adaptive fire extinguishing mechanism 5 is composed of an outer shell 33 and a fire extinguishing dry powder 34. The outer shell 33 is connected to the cover plate 4 through an insertion, and the fire extinguishing dry powder 34 is filled in the inner part of the outer shell 33. The bottom end of the outer shell 33 is provided with a plurality of strip-shaped through grooves 35, and the bottom end of the inner part of the strip-shaped through grooves 35 is fixedly provided with a plurality of diaphragms 36. The diaphragms 36 are made of non-fire-resistant material. The bottom end of the inner part of the outer shell 33 is formed with a plurality of V-shaped grooves 37. The outer shell 33 is fixedly connected to the cover plate 4 by a plurality of bolts 38. The top end of the outer shell 33 is fixedly provided with a strip-shaped feed groove 39, and the top end of the strip-shaped feed groove 39 is provided with a strip-shaped cover 40.

[0042] When a fire occurs inside the bus duct, the diaphragm 36 shrinks and breaks when encountering fire. At this time, the fire extinguishing dry powder 34 is discharged through the strip through groove 35 to achieve the fire extinguishing function. The setting of the V-shaped groove 37 can facilitate the discharge of the fire extinguishing dry powder 34, and the setting of the strip feeding groove 39 and the strip sealing cover 40 can facilitate the addition of the fire extinguishing dry powder 34.

[0043] Embodiment 4, based on embodiment 1, Figure 2It is shown that the air inlet heat dissipation assembly 6 is composed of an air inlet cover 41, a fan 42, an air inlet pipe 43 and an air inlet filter 44. The air inlet cover 41 is inserted and connected to one end of the top of the cover plate 4, the fan 42 is fixedly connected to the top of the air inlet cover 41, the air inlet pipe 43 is fixedly connected between the air inlet cover 41 and the fan 42, and the air inlet filter 44 is fixedly connected to the air inlet of the fan 42.

The exhaust cover 45 is inserted and connected to the other end of the top of the cover plate 4, and the exhaust filter 46 is fixedly connected to one end of the exhaust cover 45.

[0044] When the bus duct is working normally, the air inlet cover 41, the fan 42 and the air inlet pipe 43 supply air into the bus duct to achieve forced air cooling and heat dissipation. The air inlet is filtered through the air inlet filter 44, and the air is exhausted through the exhaust cover 45. The exhaust filter 46 can prevent debris, mice, etc. from entering the bus duct.

[0045] During operation, by setting up an overheating automatic separation mechanism composed of a limit support component, a first movable contact component, a second movable contact component and a thermal deformation component, it is possible to achieve automatic disconnection when the bus duct is overheated due to a short circuit or the like, thereby ensuring the safety of the bus duct, avoiding fire in the bus duct, and improving the safety of use; by setting up an adaptive fire extinguishing mechanism composed of an outer shell and fire extinguishing dry powder, it is possible to achieve automatic fire extinguishing when a fire occurs inside the bus duct, avoiding the spread of fire and causing greater losses, and further improving the safety of the use of the bus duct; by setting up an air inlet heat dissipation component composed of an air inlet hood, a fan, an air inlet pipe and an air inlet filter, and an exhaust component composed of an exhaust hood and an exhaust filter, it is possible to achieve air cooling and heat dissipation inside the bus duct, improve the heat dissipation efficiency when the bus duct is working normally, and thereby improve the service life and safety of use of the bus duct.
