Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct for power supply and distribution with adjustable interfaces. Background Art

[0002] Busbar refers to a product made of high-conductivity copper or aluminum materials for transmitting electrical energy. It has the ability to collect and distribute electricity. It is the main conductor used to transmit electrical energy in power stations or substations. The busbar transmits the electrical energy output by generators, transformers or rectifiers to various users or other substations. Bus duct is a device used to place busbars.

[0003] Traditional bus ducts have a short service life and are prone to busbar scattering due to pulling of the busbar ports. They lack protective and restrictive functions. For this reason, we have proposed a bus duct for power supply and distribution.

[0004] Traditional bus ducts have a short service life and are prone to busbar scattering due to pulling on the busbar ports, and lack protective and restrictive functions.

[0005] As disclosed in Chinese patent CN211629810U, a bus duct for power supply and distribution is proposed. By pulling the positioning plate, the fixing plate is synchronously raised, so that the gap between the fixing plate and the base is blocked with an object, so that the busbar is laid on the sponge body of the constraint opening and passes through the rubber sleeve at the other end, so that the blocking object is removed after wiring. Under the elastic force of the elastic device, the busbar is clamped in the sponge body between the pressure plate and the clamping plate, and the other end can be elastically clamped under the action of the rubber sleeve, and finally fixed by fixing the locking bolt to complete the fixation, so that the busbar can be restricted to prevent it from being pulled off. Therefore, under the joint action of various components, the busbar can be laid conveniently and can adapt to busbars of different diameters. At the same time, the busbar can be restricted after laying, so that it is not easy to be pulled, and it can avoid damage and scattering.

[0006] However, in the prior art, when the bus duct is connected, the size of the interface position is not easy to adjust, which results in the bus duct being relatively inflexible during installation, affecting work efficiency, and being inconvenient to disassemble and assemble after connection.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A bus duct for power supply and distribution with adjustable interface comprises a duct body 1, a wire management structure is installed inside the duct body 1, connection structures are installed at the left and right ends of the duct body 1, and heat dissipation structures are installed at the top and bottom of the duct body 1.

[0031] The connection structure includes a transmission unit and a connection unit, wherein the connection unit includes a connection plate 205, a clamping column 206 is installed in the middle of the connection plate 205, a pulling block 208 is installed at one end of the clamping column 206, a spring 207 is connected to one end of the pulling block 208 close to the clamping column 206, and a limit block 209 is fixedly installed in the middle of the connection plate 205. The transmission unit includes a guide rail 201, a transmission member 202 is installed inside the guide rail 201, a knob 203 is installed at one end of the transmission member 202, and a slider 204 is connected to the middle of the outer surface of the transmission member 202.

[0032] The outer surface of the slider 204 is fixedly connected to the connecting plate 205, and the outer surface of the slider 204 is slidably connected to the inside of a convex sliding groove opened in the middle of the guide rail 201. The end of the spring 207 away from the pulling block 208 is fixedly connected to the connecting plate 205, and the limit block 209 is installed in the middle of the side of the connecting plate 205 away from the guide rail 201.

[0033] The wire management structure includes a slot cover 101, a slide 102 is installed on the bottom surface of the slot cover 101, a slide column 103 is connected inside the slide 102, a spring 104 is installed on the end of the slide 102 away from the slot cover 101, a wire clamping plate 105 is installed on the end of the slide column 103 away from the slide 102, and a wire sleeve 106 is provided at the bottom of the middle of the left and right sides of the slot cover 101. The bottom surface of the slot cover 101 is detachably connected to the top of the slot body 1, the bottom end of the bottom slide 102 is connected to the bottom surface of the slot body 1, the middle of the left and right ends of the slot body 1 is connected to the guide rail 201, and the wire sleeve 106 is installed inside the through hole opened in the middle of the left and right sides of the slot body 1.

[0034] By setting the connection structure, rotating the knob 203 drives the transmission member 202 to drive, so that the two connecting plates 205 at the same end can be close to each other, so that they can be connected and installed using the clamping column 206 and the limit block 209, making disassembly and assembly more convenient and relatively more flexible.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, the heat dissipation structure includes a ventilation box 301, fans 302 are installed at the left and right ends of the ventilation box 301, a bump 303 is provided at the bottom of the ventilation box 301, a cooling box 304 is provided at the bottom of the ventilation box 301, a condenser 305 is installed at the bottom of the cooling box 304, and a fin 306 is installed in the middle of the top surface of the condenser 305.

[0038] By setting the heat dissipation structure, turning on the fan 302 can generate airflow inside the ventilation box 301. The flow rate is enhanced when the airflow flows through the protrusion 303. The Bernoulli principle is used to pump the air inside the slot body 1 to dissipate heat. At the same time, the ventilation holes opened at the bottom of the slot body 1 are used to pump the cold air conducted by the condenser 305 and the fins 306, thereby achieving a better heat dissipation effect.

[0039] When the inside of the slot body 1 is to be cooled, the fans 302 at the left and right ends of the ventilation box 301 are turned on for blowing air. The air pressure inside the ventilation box 301 can be lowered by utilizing the air flow velocity passing through the inside of the ventilation box 301. At the same time, when the air flow passes through the arc on the surface of the protrusion 303, the flow velocity becomes faster. By utilizing the Bernoulli principle, the air inside the slot body 1 can be pumped through the air holes opened on the top surface of the slot cover 101, thereby achieving the effect of cooling the temperature inside the slot body 1. At the same time, the condenser 305 is turned on to conduct cold air using the fins 306, and the cold air is pumped into the inside of the slot body 1 using the air holes opened at the bottom of the slot body 1, thereby achieving better heat dissipation and cooling effect.
