Technical Field

[0001] The utility model relates to the technical field of busbar bridges, in particular to a bent busbar bridge. Background Art

[0002] In the field of high-voltage electrical equipment, the bus bridge is a high-voltage power transmission and distribution device, which is generally installed between switch cabinets or transformers. The bus bridge is a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise at the connection points at both ends of the bus duct and the branch port are greatly reduced.

[0003] With the continuous development of building design, when people install busbar bridges in buildings, they need to make multiple turns to supply indoor electricity, which is very time-consuming and manpower-consuming. If it rains, they also need to have a certain ability to protect the roof from leaking. Ordinary busbar bridges do not have waterproof capabilities and cannot meet people's usage needs.

[0004] Therefore, we propose a bent busbar bridge to solve the above problems. Utility Model Content

[0011] Preferably, two layers of baffles, upper and lower, are arranged inside the bridge frame body, and L-shaped angle irons are welded at both ends of the top (or bottom) of the baffles.

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a bent busbar bridge, comprising a bridge body 1, a cover plate 2 is installed on the top of the bridge body 1, and slide grooves 6 are arranged on both sides of the top of the bridge body 1, rubber pads 3 are installed at both ends of the cover plate 2, an L-shaped angle iron 4 is arranged inside the bridge body 1, and the top of the L-shaped angle iron 4 at the upper position is connected to a baffle 5, and the bottom of the L-shaped angle iron (4) at the lower position is connected to a baffle 5, a connecting rod 10 is installed inside the L-shaped angle iron 4, and a universal joint 8 is arranged at one end of the connecting rod 10, adjustment holes 7 are arranged on both sides of the bridge body 1, and a connecting plate 9 is installed on the surface of the bridge body 1.

[0022] The bridge frame body 1 forms a sliding structure with the cover plate 2 through the slide groove 6, and the front and rear ends of the slide groove 6 pass through the bridge frame body 1. When repairing the internal parts of the bridge frame body 1, the cover plate 2 is pulled out by sliding between the slide groove 6 and the cover plate 2, thereby reducing the maintenance time.

[0023] The connecting rod 10 is adjusted to the required length through the adjustment hole 7. When the bridge frame body 1 needs to be bent at a specified position, the distance between the two ends of the bridge frame body 1 will decrease or increase in a contrasting manner. The length of the connecting rod 10 is changed by adjusting the hole 7 to reduce the time required for the turning.

[0024] The edge of the cover plate 2 is set as an inclined surface, and rubber pads 3 are installed on the inclined surfaces at both ends of the cover plate 2. When the roof leaks, the inclined design of the top of the cover plate 2 can resist most of the water flow and reduce the amount of water entering. The inclined surfaces at both ends of the cover plate 2 make the connecting surface after the turning more fit, and the rubber pads 3 on the inclined surface reduce the wear on the bridge frame body 1 after bending.

[0025] The universal joint 8 includes a transmission shaft fork 801, a cross shaft 802 and a universal joint base 803. The universal joint base 803 is installed at the rear of the transmission shaft fork 801, and the front end of the transmission shaft fork 801 is cross-connected to the cross shaft 802. The rear of the universal joint base 803 is connected to a connecting rod 10. When turning, the transmission shaft fork 801 will rotate on the cross shaft 802, and the transmission shaft forks 801 at the left and right ends are cross-connected and installed on the cross shaft 802. This structure greatly increases the diversity of rotation directions.

[0026] Two layers of baffles 5 are arranged inside the bridge body 1, and L-shaped angle irons 4 are welded at both ends of the top (or bottom) of the baffle 5. The baffle 5 is then arranged with a three-layer structure inside. Lines that need to be placed separately or are relatively large can be placed in the remaining levels. The L-shaped angle irons 4 welded at both ends have a certain supporting structure to prevent the baffle 5 from falling directly when damaged.

[0027] A connecting plate 9 is installed on the surface of the bridge frame body 1. The connecting plate 9 is installed after the bridge frame body 1 is bent, so the shape of the connecting plate 9 is determined according to the shape after bending. The connecting plate 9 can be used to protect the universal joint 8 and prevent water from entering, reducing internal damage.

[0028] Working principle: When using the bendable busbar bridge, first, lay the bridge body 1 along the required position. After reaching the designated bending location, bend the universal joint 8, and the drive shaft fork 801 will rotate on the cross shaft 802, and the drive shaft forks 801 at the left and right ends are cross-connected and installed on the cross shaft 802. The connecting rod 10 connected to the bottom of the universal joint base 803 changes its size by adjusting the adjustment hole 7, that is, driving the connecting rod 10 to slide in the L-shaped angle iron 4, and using bolts to cooperate with the adjustment hole 7 to lock the connecting rod 10 on the bridge body 1 to achieve the bending effect.

[0029] Secondly, the edge of the cover plate 2 on the top of the bridge frame body 1 is set as an inclined surface, and rubber pads 3 are installed on the inclined surfaces at both ends of the cover plate 2. When the roof leaks, the inclined design of the top of the cover plate 2 can resist most of the water flow and reduce the amount of water inflow. The inclined surfaces at both ends of the cover plate 2 make the connecting surface after the turning more fit, and the rubber pads 3 on the inclined surface reduce the wear of the bridge frame body 1 after bending. The inside of the bridge frame body 1 is provided with an upper and lower layer of baffles 5 for layering. The L-shaped angle irons 4 welded at both ends of the baffle 5 have a certain support structure to prevent the baffle 5 from falling directly when damaged.

[0030] Then, when maintenance is needed, the cover plate 2 can be pulled out by sliding between the slide groove 6 and the cover plate 2 .

[0031] Finally, a connecting plate 9 is installed on the surface of the bridge body 1. After the turning is completed, the universal joint 8 is exposed outside and needs to be enclosed by the connecting plate 9. Because the bending direction is not fixed, the shape of the connecting plate 9 needs to be determined according to the shape after bending, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
