[0024] The following embodiments can be understood as representing a part of the local structure of this utility model, or as a combination of embodiments explaining the broader structural connotation of this utility model.

[0025] Example 1

[0026] A type of cross-branch power supply system for road surfaces, such as Figures 1-6As shown, the system includes a pavement load-bearing mechanism 1, an insulating cast-in-place body 4, a busbar 12, a junction box 2, and an underground distribution box. The pavement load-bearing mechanism 1 includes a housing, within which the insulating cast-in-place body 4 is connected via a vibration damping mechanism. Both the insulating cast-in-place body 4 and the housing span the pavement surface 01. The busbar 12 runs through the insulating cast-in-place body 4. Junction boxes 2 are connected to both sides of the housing. The junction boxes 2 are equipped with industrial connectors. The busbar 12 is electrically connected to the industrial connectors via flexible cable connectors 3. The industrial connectors are electrically connected to the underground distribution box via cables. The underground distribution box includes a distribution box body 19. A load-bearing steel plate 20 is provided on the top of the distribution box body 19, and the top of the load-bearing steel plate 20 is flush with the ground.

[0027] In this embodiment, the pavement load mechanism 1 is laid on the pavement, allowing vehicles to pass through, thus avoiding the tedious construction of digging trenches on the pavement and the damage to the pavement; the underground distribution box has the conventional structure and function of existing distribution boxes, and in addition, the top is provided with a load-bearing steel plate 20, which greatly reduces the impact of the distribution box being set on the ground on traffic.

[0028] Example 2

[0029] like Figure 4 As shown, the bottom of the distribution box body 19 is provided with a water collection tank 23. The water collection tank 23 is connected to a water pump (not shown in the figure) on the ground through a pipe (not shown in the figure). A water level sensor (not shown in the figure) is provided in the water collection tank. The water level sensor is electrically connected to a control circuit board (not shown in the figure). The control circuit board is electrically connected to the water pump through a wire. The control circuit board is located inside the distribution box body (not shown in the figure). The control circuit board is also connected to a control panel (not shown in the figure) located on the ground through a cable.

[0030] In this embodiment, when water accumulates in the collection tank, it can be drained manually or automatically. Furthermore, the underground distribution box should possess sufficient structural strength and waterproofing capabilities, and be equipped with relevant electrical units; the related designs are common technologies and will not be elaborated upon here.

[0031] Example 3

[0032] like Figure 1 , 2 As shown, the side cross-section of the shell is a trapezoidal structure, including a top plate 6, ramp plates 5 located on the front and rear sides of the top plate 6 and fixedly connected to the ends of the top plate 6 at their top, and a bottom plate (not marked in the figure) opposite to the top plate 6 and connected to the bottom of the two ramp plates 5 at both ends. Several vibration damping units are provided below the top plate 6, and the vibration damping units are connected to each other along the direction of the pavement. The top plate 6 and the bottom plate are connected by vibration damping units, and the bottom plate is used to be laid on the pavement.

[0033] like Figure 1 , 2 As shown, the vibration damping unit includes a rectangular support steel pipe 8, which spans across the pavement 01 together with the shell and provides support for the top plate 6. A vibration damping pipe 9 with a rectangular cross-section is fitted inside the rectangular support steel pipe 8, with the two diagonals of the rectangle arranged horizontally and vertically respectively. A force transmission pipe 11 with a rectangular cross-section is fitted inside the vibration damping pipe 9. The four sides of the force transmission pipe 11 are parallel to the four sides of the rectangular support steel pipe 8. A cylindrical insulating casting body 4 is provided inside the force transmission pipe 11. The outer wall of the insulating casting body 4 is clearance-fitted with the inner wall of the force transmission pipe 11. Both ends of the insulating casting body 4 extend into the junction box. The four edges of the vibration damping pipe 9 are rounded, and the four rounded edges 10 contact the inner wall of the rectangular support steel pipe 8. A first vibration damping component is connected between the outer wall of the vibration damping pipe 9 and the inner wall of the rectangular support steel pipe 8, and a second vibration damping component is connected between the vibration damping pipe 9 and the force transmission pipe 11.

[0034] like Figure 2 , 5 As shown in Figure 6, the first damping assembly includes multiple first damping springs 13 arranged in a spiral shape. One end of each first damping spring 13 is connected to the outer wall of the damping tube 9, and the other end is connected to the inner wall of the rectangular support steel tube 8 in a transverse or longitudinal direction. The elastic force of the first damping spring 13 satisfies the following condition: when the top of the housing is subjected to an impact force pointing obliquely downward, the top of the housing and the top of the rectangular support steel tube 8 deform and push the damping tube to rotate. Figure 6 As shown, when the damping tube 9 rotates, each of the first damping springs 13 is stretched. After the impact force, the deformation is restored under the elastic force of each of the first damping springs 13.

[0035] like Figure 2 , 5 As shown, the second vibration damping component includes a second vibration damping spring connected between the outer surfaces of the four side walls of the force transmission tube and the corresponding inner corners of the vibration damping tube 9. The second vibration damping spring is arranged longitudinally or horizontally. The stiffness of the upper and lower side walls of the force transmission tube 11 is sufficient to overcome the elastic force of the upper second vibration damping spring A14 and the lower second vibration damping spring B16. The stiffness of the left and right side walls is sufficient to overcome the tension of the left second vibration damping spring C15 and the tension of the right second vibration damping spring D17.

[0036] like Figure 2 As shown, adjacent rectangular support steel pipes 8 are tightly fitted and welded together, and the top and bottom ends of the rectangular support steel pipes 8 are welded to the top plate and bottom plate respectively.

[0037] like Figure 1 , 2As shown, several triangular support ribs 7 are welded between the ramp plate 5 and the outer wall of the adjacent rectangular support steel pipe 8. The support ribs 7 are made of low carbon steel or shape memory alloy.

[0038] Example 4

[0039] like Figures 1-6 As shown, this embodiment discloses the construction content of a cross-type busbar power supply system for a road surface, including: the insulating cast body 4 is a cylinder. When a vehicle passing through the road surface impacts the top plate, the insulating cast body 4 rotates relative to the force transmission pipe 11 or vibrates with the force transmission pipe 11, and the force transmission pipe 11 cannot apply a destructive force to the insulating cast body 4.

[0040] Furthermore, since busbar 12 is connected to the industrial connector via flexible cable connector 3, and the flexible cable connector 3 has a length margin to cope with vibration, the function of busbar 12 is not affected, and the insulating casting 4 itself is not damaged by vibration; this is specifically reflected in the following two aspects:

[0041] (1) As Figure 5 As shown, when the top plate 6 is subjected to a vertically downward impact force, the combined action of the damping pipe 9, the first damping spring 13, and the second damping spring promotes the deformation and restoration of the top plate 6 and the rectangular support steel pipe 8. During this process, because the stiffness of the upper and lower side walls of the force transmission pipe 11 is sufficient to overcome the elastic force of the upper second damping spring A and the lower second damping spring B, and the stiffness of the left and right side walls is sufficient to overcome the tension of the left second damping spring C and the right second damping spring D, the insulating casting body 4 and the busbar 12 are not damaged.

[0042] (3) Figure 6 As shown, when the top plate 6 is subjected to a downward impact force 26, the damping pipe 9 rotates relative to the rectangular support steel pipe 8 under the pushing force of the deformation at the top of the rectangular support steel pipe 8, and each of the first damping springs 13 is stretched. After the impact force, the damping pipe 9 resets and pushes the top wall of the rectangular support steel pipe 8 and the top plate 6 through the elastic force of each of the first damping springs 13, promoting the reset of the deformation. During this process, due to the inertia of the insulating casting body 4, the force transmission pipe 11 rotates relative to the insulating casting body 4, and will not cause damage to the insulating casting body 4.

[0043] It should be noted that during use, due to vertical or downward tilting impact forces, the top plate and the top wall of the rectangular support steel pipe will deform to a certain extent. This deformation includes both elastic and plastic deformation. The elastic force of the first damping spring is set to facilitate the recovery of plastic deformation caused by tilting impact forces. The combined effect of the damping tube 9, the first damping spring 13, and the second damping spring is set to facilitate the recovery of plastic deformation caused by vertical impact forces. The structural parameters of the damping tube or springs can be determined experimentally. When a downward tilting force impacts, the top plate and the top wall of the rectangular support steel pipe deform. Although the damping tube rotates, its top chamfered portion remains in contact with the rectangular support steel pipe. Under the tension of multiple first damping springs, a damping effect against tilting impact forces is achieved through its own torsional force. Due to the complexity of the modular construction and transportation materials in marine shipbuilding engineering, this damping effect against tilting impact forces is particularly important for ensuring the safety of the busbar.
