[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 7 , the present invention provides a technical solution:

[0034] A high-protection and high-strength cast-type bus duct, comprising a bus duct body 1, bus terminals 3 are arranged at both ends of the bus duct body 1, the bus terminals 3 are composed of a plurality of copper bars distributed at equal distances, the bus terminals 3 at both ends of the bus duct body 1 are built-in with connection structures, and a plurality of bus duct bodies 1 are connected and fixed by the connection structure in a head-to-tail manner;

[0035] The upper end surface of the bus duct body 1 is provided with heat dissipation mechanisms 2 at equal distances, and the heat dissipation of the copper bar inside the bus duct body 1 is achieved by heat conduction cooling and heat dissipation through the heat dissipation mechanism 2 in the form of air cooling heat conduction;

[0036] The front and rear sides of the bus duct body 1 are fixedly connected with buffer springs with a wave-like structure, which are used to protect the bus duct body 1 and reduce the impact force of external objects on the bus duct body 1.

[0037] Specifically, the heat dissipation mechanism 2 includes a heat-conducting copper sheet 5 with a serpentine structure built into the bus duct body 1, and the heat-conducting copper sheet 5 is connected end to end, and a guide groove 14 is formed inside the heat-conducting copper sheet 5, and the copper bar in the bus terminal 3 passes through the guide groove 14.

[0038] Specifically, the heat-conducting copper sheet 5 has a hollow structure design inside, and a driving assembly is built in at the end and tail connection points at both ends. The upper end surface of the bus duct body 1 is fixedly connected to a ventilating tube 4, and heat dissipation fins 6 are distributed in a ring at equal distances inside the ventilating tube 4, and the heat dissipation fins 6 are fixedly connected to the heat-conducting copper sheet 5. A dual-axis motor 7 is fixed in the middle of the heat dissipation fin 6, and the top output shaft of the dual-axis motor 7 is fixedly connected to the fan blade 8. The driving assembly includes a circulation tube 9 fixed in the ventilating tube 4, and the output shaft at the lower end of the dual-axis motor 7 extends through the circulation tube 9 and is fixedly connected to a transmission reciprocating screw rod 10. A piston plate 13 is provided in the circulation tube 9, and the piston plate 13 is spirally connected to the transmission reciprocating screw rod 10. A water inlet hole 12 and a drain hole 11 are respectively opened on the outer lower side of the circulation tube 9, and the water inlet hole 12 and the drain hole 11 are respectively connected and fixed to the two ends of the heat-conducting copper sheet 5, and the water inlet hole 12 and the drain hole 11 have built-in one-way valves, and the circulation tube 9 and the heat-conducting copper sheet 5 have built-in coolant.

[0039] By adopting the above technical solution, when working, the dual-axis motor 7 is connected to the external power supply and the controller, and the dual-axis motor 7 is controlled to drive the fan blades 8 and the transmission reciprocating screw 10 to rotate. At this time, the heat-conducting copper sheet 5 absorbs the heat of the copper bar inside the bus duct body 1 through heat conduction, and then dissipates heat under the rotation of the fan blades 8 through heat conduction and the heat dissipation fins 6. This method is a single air-cooled heat dissipation. The user can also use the external liquid injection valve of the circulation cylinder 9 to like the inside of the circulation cylinder 9. Under the action of the drainage hole 11, the circulation cylinder 9 and the heat-conducting copper sheet 5 are filled with liquid. Coolant is injected inside. When the dual-axis motor 7 drives the transmission reciprocating screw 10 to rotate, the piston plate 13 connected to the transmission reciprocating screw 10 spirally drives and moves back and forth up and down inside the circulation tube 9. The air plug plate moves down to squeeze the coolant in the circulation tube 9 into the heat-conducting copper sheet 5 through the drainage hole 11. The air plug plate moves up to suck the coolant inside the heat-conducting copper sheet 5 into the circulation tube 9 through the water inlet hole 12. This cycle is repeated to achieve liquid cooling. The third method uses air cooling and liquid cooling together to achieve the effect of cooling and dissipating heat for the bus duct main body 1.

[0040] Specifically, the connection structure includes a copper bar 1 31 and a copper bar 2 32, wherein the copper bar 1 31 and the copper bar 2 32 are plugged and self-locked, and the adjacent surfaces of the copper bar 2 32 and the copper bar 1 31 are provided with a T-shaped plug-in groove 33, and a rack 34 is fixed in the plug-in groove 33, and the copper bar 1 31 is matched and plugged and fixed with the plug-in groove 33.

[0041] The adjacent surfaces of the copper bar 1 31 and the copper bar 2 32 are fixed with elastic tooth plates 35 , and the elastic tooth plates 35 are meshed with the racks 34 , and both are relatively distributed in a right-angled trapezoidal structure design.

[0042] By adopting the above technical solution, when working, the user can connect several bus duct bodies 1 end to end through the bus terminal 3, and plug the copper bar 2 32 into the plug-in slot 33 in the copper bar 1 31. At this time, the rack 34 on the copper bar 2 32 and the elastic tooth plate 35 on the copper bar 1 31 are engaged and fixed with each other to achieve self-locking fixation, thereby achieving the connection effect, and then the insulating shell can be sleeved at the connection.

[0043] Working principle: When working, the dual-axis motor 7 is connected to the external power supply and the controller, and the dual-axis motor 7 is controlled to drive the fan blades 8 and the transmission reciprocating screw 10 to rotate. At this time, the heat-conducting copper sheet 5 absorbs the heat of the copper bar inside the bus duct body 1 through heat conduction, and then dissipates heat through heat conduction and the heat dissipation fins 6 under the rotation of the fan blades 8. This method is a single air-cooled heat dissipation. The user can also use the external liquid injection valve of the circulation cylinder 9 to like the inside of the circulation cylinder 9. Under the action of the drainage hole 11, the coolant is injected into the circulation cylinder 9 and the heat-conducting copper sheet 5. When the dual-axis motor 7 drives the transmission reciprocating screw 10 to rotate, the piston plate 13 connected to the transmission reciprocating screw 10 spirally drives and moves up and down inside the circulation cylinder 9. When the air plug plate moves downward, the coolant in the circulation cylinder 9 is squeezed into the heat-conducting copper sheet 5 through the drainage hole 11. When the air plug plate moves upward, suction is performed, and the coolant inside the heat-conducting copper sheet 5 is sucked into the circulation cylinder 9 through the water inlet hole 12. This cycle is repeated to achieve liquid cooling. The third method uses air cooling and liquid cooling together to achieve the effect of cooling and dissipating the heat of the bus duct main body 1. During operation, the user can connect several bus duct main bodies 1 end to end through the bus terminal 3, and plug the copper bar 2 32 into the plug-in slot 33 in the copper bar 1 31. At this time, the rack 34 on the copper bar 2 32 and the elastic tooth plate 35 on the copper bar 1 31 are meshed and fixed with each other to achieve self-locking fixation, thereby achieving the effect of connection, and then the insulating shell can be sleeved at the connection.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
