At the same time, the surface of the storage plate is covered with a fireproof coating, a protective shell is arranged on the side of the storage box, and a slide groove is opened on the side of the storage box. The protective shell is connected to the storage box through a sliding rod, and a spring is arranged on the side of the sliding rod. At the same time, a hole is reserved at the end of the protective shell, a fixed plate is fixed in the middle position of the storage box, and a fixed plate is installed in the middle position of the fixed plate. There is a knob, and the side of the knob is connected to a fixed rod through an elastic rope, and a limiting block is connected to the middle position of the fixed rod. One end of the first connecting block is fixed to the bottom of the protective shell, and the other end of the first connecting block is connected to the second connecting block through a chain. This utility solves the problem that the existing bus duct has poor protection function. During the use of the bus duct, it is affected by external factors and is prone to failure, affecting the normal use of the bus duct. In addition, the existing bus duct is not convenient for regular maintenance. The bus duct that has not been inspected for a long time is prone to damage, affecting the normal power supply of electrical equipment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2A bus duct with multiple protection functions in this embodiment includes a side panel 1, a cover panel 2 is provided above the side panel 1, and a mounting mechanism 3 for facilitating the disassembly and assembly of the cover panel 2 is provided on the side panel 1, so as to facilitate the maintenance of the bus duct and improve the maintenance efficiency. A bus plate 4 is provided on the left side of the side panel 1, and a protection mechanism 5 for protecting the internal structure of the bus duct is provided on the bus plate 4, so that the bus duct can be protected by multiple protections and can keep working in various harsh environments.

[0023] There are two side panels 1, which are symmetrically distributed left and right about the central axis of the cover panel 2; there are two cover panels 2, which are symmetrically distributed up and down about the central axis of the side panel 1, so that the bus duct can be protected all around.

[0024] See also Figure 3 In order to facilitate the maintenance of the bus duct and improve the efficiency of maintenance, the mounting mechanism 3 in this embodiment includes a mounting block 301, which is fixed to the right side of the side plate 1. A first connecting hole 302 is provided on the lower surface of the mounting block 301, and a second connecting hole 303 is provided on the inner bottom wall of the cover plate 2. An insulating bolt 304 is provided inside the first connecting hole 302. The first connecting hole 302 is aligned with the second connecting hole 303, and the insulating bolt 304 is inserted into the first connecting hole 302 and the second connecting hole 303 to locate and connect the mounting position of the mounting block 301 and the cover plate 2. The other end of the insulating bolt 304 penetrates and extends to the cover plate 2. The inner side of the bus duct is provided with an insulating nut 305 which is threadedly connected to the outer side. An insulating gasket 306 is provided under the insulating nut 305. The insulating gasket 306 is passed through the insulating bolt 304 and the insulating nut 305 is connected to the insulating bolt 304. The insulating nut 305 is tightened to fix the cover plate 2 and the side plate 1 tightly, so that the bus duct shell is more stable and the protection effect of the bus duct is improved. When performing maintenance work, the upper insulating nut 305 is removed. The insulating gasket 306 can prevent the insulating nut 305 from being too tightly fitted to the cover plate 2 and causing adhesion. After removing the insulating nut 305, the upper cover plate 2 can be removed to facilitate maintenance of the internal busbar 4.

[0025] In this example, two mounting blocks 301 are distributed on each side panel 1, and are symmetrically distributed up and down with respect to the central axis of the side panel 1, so that the contact positions of the side panel 1 and the cover plate 2 can be fixed, thereby improving the stability of the bus duct. The inner diameters of the first connecting hole 302, the second connecting hole 303 and the insulating gasket 306 are all adapted to the outer diameter of the insulating bolt 304, and the outer diameter of the insulating nut 305 is larger than the inner diameter of the insulating gasket 306, so that the insulating nut 305 can fix the cover plate 2 and the mounting block 301 on the insulating gasket 306.

[0026] See also Figure 4In order to make the bus duct be protected by multiple layers and to enable the bus duct to keep working in various harsh environments, the protection mechanism 5 in this embodiment includes a sealing belt 501, which is fixed to the outer side of the bus plate 4. The number of the bus plates 4 is not less than two, and they are equidistantly distributed between the two side plates 1. The sealing belt 501 can protect the bus plates 4, thereby preventing the current from accidentally short-circuiting inside the bus duct, and can protect the outer layer material of the bus plate 4 in the case of poor installation environment or easy corrosion, extend the service life of the bus plate 4, and reduce electromagnetic interference. A heat sink 502 is fixed on the right side of the right side plate 1, and the left side of the heat sink 502 penetrates and extends to the right side On the left side of board 1, when the bus duct is working, the internal busbar board 4 will generate heat. The heat dissipation efficiency can be improved through the heat sink 502 to prevent the temperature of the busbar board 4 from being too high. The inner bottom wall of the upper cover plate 2 is fixed with a fire-retardant coating 503. When a fire occurs outside the bus duct, the temperature of the flame will be transmitted to the cover plate 2. The fire-retardant coating 503 will quickly disperse the temperature after being exposed to high temperature to prevent the high temperature from being transmitted to the inside of the bus duct, causing the sealing belt 501 to be carbonized by heat and affect subsequent work. Sealing pads 504 are fixed on the opposite sides of the two cover plates 2. The sealing pads 504 can seal the inside of the bus duct to avoid the chimney effect, improve safety, and also have a waterproof effect.

[0027] In this example, the length of each sealing gasket 504 is adapted to the length of the right side panel 1, and the width of each sealing gasket 504 is adapted to the distance between the two side panels 1, thereby improving the sealing effect on the front and rear sides of the bus duct. Multiple heat sinks 502 are distributed on each side panel 1 and are evenly distributed on each side panel 1, thereby improving the heat dissipation effect of the bus duct.

[0028] The working principle of the above embodiment is:

[0029] (1) When installing the bus duct, firstly, fit the mounting block 301 on the side plate 1 with the cover plate 2, and align the first connection hole 302 with the second connection hole 303. Then, insert the insulating bolt 304 into the first connection hole 302 and the second connection hole 303, locate and connect the mounting position of the mounting block 301 and the cover plate 2, then pass the insulating gasket 306 through the insulating bolt 304 and connect the insulating nut 305 with the insulating bolt 304, tighten the insulating nut 305 so that the cover plate 2 and the side plate 1 are tightly fixed, so that the outer shell of the bus duct is more stable and the protection effect of the bus duct is improved. When performing maintenance work, remove the upper insulating nut 305. The insulating gasket 306 can prevent the insulating nut 305 from being too tightly fitted with the cover plate 2 and causing adhesion. After removing the insulating nut 305, the upper cover plate 2 can be removed to facilitate maintenance of the internal busbar 4.

[0030] (2) After the bus duct is installed and connected, since each bus board 4 is installed closely together and the sealing gasket 504 can seal the inside of the bus duct, the chimney effect can be avoided and the safety can be improved. The sealing tape 501 can protect the bus boards 4, thereby avoiding accidental short circuit of the current inside the bus duct. In addition, it can protect the outer material of the bus board 4 in the case of poor installation environment or corrosion, extend the service life of the bus board 4, and reduce electromagnetic interference. When the bus duct is working, the internal bus board 4 will generate heat. The heat dissipation efficiency can be improved by the heat sink 502 to prevent the temperature of the bus board 4 from being too high. When a fire occurs outside the bus duct, the temperature of the flame will be transferred to the cover plate 2. The fire retardant coating 503 will quickly disperse the temperature after being exposed to high temperature, preventing the high temperature from being transferred to the inside of the bus duct, causing the sealing tape 501 to be heated and carbonized, affecting subsequent work.
