[0032] The present invention provides a busbar bridge capable of preventing sagging.

[0033] like Figures 1 to 5The anti-sagging busbar bridge shown in the figure comprises a bridge body 1, a fixing seat 4 and at least one bridge frame 5, the bridge body 1 is a box structure with open ends, and the two ends of the box structure extend outward to make the bridge body 1 in a long strip shape; the fixing seat 4 is used to be fixed at a high place, and two first slide grooves 41 parallel to the extension direction of the bridge body 1 are arranged at intervals on the side of the fixing seat 4 facing the bridge body 1, and a plurality of connecting ports 43 are arranged at intervals between the two first slide grooves 41 along the length direction of the first slide grooves 41, and a slider 42 is slidably arranged in each first slide groove 41, and the number of sliders 42 in each first slide groove 41 is the same as the number of the bridge frame 5; a plurality of lifting ears 11 are arranged at intervals on one side between the two ends of the bridge body 1 along the extension direction of the bridge body 1, and the lifting ears 11 and the connecting ports 43 are connected by first cables 6 The bridge frame 5 comprises a transverse plate 51 located on the side of the bridge body 1 away from the lifting ear 11, and two connecting plates 53 located on the side of the transverse plate 51 facing the lifting ear 11. The transverse plate 51 is fixedly connected to the two connecting plates 53 respectively. One end of a connecting plate 53 is vertically connected to one end of the transverse plate 51, and the other end is connected to a slider 42 in a first slide groove 41 through a second cable; one end of the other connecting plate 53 is vertically connected to the other end of the transverse plate 51, and the other end is connected to a slider 42 in another first slide groove 41 through a third cable; the transverse plate 51 is provided with a connecting through hole 52, and the side of the bridge body 1 facing the transverse plate 51 is provided with a plurality of fixing holes arranged in compartments along the extending direction of the bridge body 1, so that the connecting through hole 52 and any fixing hole are fixedly connected by bolts.

[0034] The arrangement of a plurality of bridge frames 5 and a plurality of lifting ears 11 enables the bridge body 1 as a whole to have multiple stress points, thus reducing the stress on each stress point of the bridge body 1 and avoiding local sagging of the bridge body 1; at the same time, the bridge frame 5 is composed of a cross plate 51 and a connecting plate 53, and the cross plate 51 converts a part of the stress points of the bridge body 1 into surface stress. The arrangement of the bridge frame 5 and the lifting ears 11 makes the stress on the bridge body 1 more uniform, further preventing the deformation of the bridge body 1 due to sagging during the lifting process, and ensuring that the bridge body 1 is stably suspended in the air.

[0035] The fixing seat 4 is generally fixed to the indoor ceiling, and the bridge frame 5 is fixedly connected by cables and sliders 42, so that the user can adjust the number and position of the bridge frame 5 according to the length of the bridge body 1. In this way, the user can better choose the length of the bridge body, as well as the number of bridge frames 5 and hanging ears 11 according to the indoor space layout to better meet the on-site needs.

[0036] Specifically, a wireless communicator and an infrared measuring device 13 which are connected to each other by signals are arranged in the bridge body 1, and the wireless communicator is connected to the user's mobile phone; the infrared measuring device 13 is arranged at one end of the bridge body 1, and a baffle 12 is arranged at the other end of the bridge body 1. The infrared measuring device 13 measures the distance between the infrared measuring device 13 and the baffle 12 to obtain the real-time detection distance and send it to the mobile phone. The mobile phone compares the received real-time detection distance with the original detection distance, and judges whether the bridge body 1 is deformed according to the difference between the real-time detection distance and the original detection distance. When the difference is greater than or less than zero, the bridge body 1 sends a deformation signal to the user's mobile phone to remind the user to check, and ensures the normal operation of the busbar by adding a new bridge frame 5 or replacing the bridge body 1.

[0037] Specifically, a fixed plate 7 is arranged between the two horizontal plates 51, and the two ends of the fixed plate 7 are respectively vertically connected to the two adjacent horizontal plates 51 and abut against the bridge body 1, so that the side of the bridge body 1 facing the ground is completely supported by the horizontal plates 51 and the fixed plates 7, further reducing the stress on each stress point of the bridge body 1.

[0038] See also Figure 5 The cross plate 51 includes a first support plate 511 and a second support plate 513 connected to each other. A slot 512 is provided at one end of the first support plate 511 close to the second support plate 513, and one end of the first support plate 511 away from the second support plate 513 is fixedly connected to a connecting plate 53; an insert block 514 is provided at one end of the second support plate 513 close to the first support plate 511, which fits with the slot 512, so that the insert block 514 can be inserted into the slot 512, and one end of the second support plate 513 away from the first support plate 511 is fixedly connected to another connecting plate 53; the slot 512 and the insert block 514 respectively have connecting through holes 52, so that bolts can pass through the two connecting through holes 52 and the fixing holes in sequence. The first support plate 511 and the second support plate 513 are detachably connected, so that the user can add or replace the bridge frame 5 at any time without adjusting the bridge body 1, so that the normal operation of the busbar is not affected during the entire replacement process.

[0039] The number of connection ports 43 is proportional to the number of lugs 11. The user can select the connection ports 43 and the lugs 11 to be connected according to the actual situation based on the stability of the connection ports 43 on the ceiling (for example, one connection port 43 is connected to multiple lugs 11 through the first cable 6, or multiple connection ports 43 are connected to one lug 11 through the first cable 6, or one connection port 43 is connected to one lug 11 through the first cable 6).

[0040] Specifically, the connection port 43 is a through hole that passes through the fixing seat 4, and is connected to the ceiling through a connecting bolt passing through the connection port 43. The hanging ear 11 and the connecting bolt are connected through a first cable 6, which can reduce the stress on the fixing seat 4 and make the bridge body 1 suspended more stably.

[0041] Specifically, a plurality of fixing through holes are provided at intervals along the length direction of the first slide groove 41 at the bottom of the first slide groove 41 of the fixing seat 4, and expansion bolts are inserted into each fixing through hole to fix the fixing seat 4 and the ceiling, leaving a moving gap between the slider 42 and the bottom of the first slide groove 41.

[0042] See also Figure 3 to Figure 4 , a plurality of busbar seats 2 parallel to the extension direction of the bridge body 1 are arranged on the side plates near the transverse plate 51 in the bridge body 1, and each busbar seat 2 is arranged at intervals along the direction from one connecting plate 53 to another connecting plate 53, and an installation space for installing the busbar is provided in the busbar seat 2; a sealing cover 21 is provided on the side of the busbar seat 2 away from the transverse plate 51, and sockets are provided at each open end of the busbar seat 2 near the bridge body 1, and the sockets are used for the busbar to be electrically connected to external devices. A special busbar seat 2 is provided to isolate the busbar from the bridge body 1, and the user installs the busbar into the installation space by opening the sealing cover 21, and isolates the installation space from the bridge body by covering the sealing cover 21, which can reduce the possibility of leakage when the busbar is energized.

[0043] The outer surfaces of the busbar seat 2 and the sealing cover 21 are both provided with an insulating layer, which further prevents the busbar from leaking electricity and penetrating the bridge body 1 .

[0044] The busbar seat 2 is provided with a second slide slot 22 parallel to the first slide slot 41, and a movable housing 3 slidably connected to the second slide slot 22. The movable housing 3 is used to place a connecting wire for connecting the busbar, so that the busbar is connected to external equipment through the connecting wire; an insulating layer is provided on the outer surface of the movable housing 3. When the setting of the movable housing 3 causes the bridge body 1 to have a size error with the actual situation, the bridge body 1 is made to reach the corresponding size through the telescopic movable housing 3, and then the connection between each substation equipment and the busbar is realized through the connecting wire.

[0045] A mounting plate 23 is provided on the side of the busbar seat 2 away from the sealing cover 21, and the side of the mounting plate 23 facing the sealing cover 21 is used for mounting the busbar; the second slide groove 22 includes a front slide groove 221 and a rear slide groove 222 symmetrically arranged at both ends of the mounting plate 23, one end of the front slide groove 221 abuts against the mounting plate 23, and the other end abuts against an opening of the bridge body 1; one end of the rear slide groove 222 abuts against the mounting plate 23, and the other end abuts against another opening of the bridge body 1; the movable shell 3 includes a front shell 31 and a rear shell 32, the front shell 31 is slidably connected to the front slide groove 221, and the rear shell 32 is slidably connected to the rear slide groove 222, and the front shell 31 and the rear shell 32 are both provided with a first limit block 33 protruding toward the sealing cover 21 at one end close to the mounting plate 23; the sealing cover 21 is respectively provided with a second limit plate protruding toward the cross plate 51 at both ends of the opening of the bridge body 1. The arrangement of the front shell 31 and the rear shell 32 allows both ends of the bridge body 1 to be telescopic. When there is a dimensional error in the bridge body 1, the bridge body 1 can be telescoped in both directions by the same distance to ensure that the bridge body 1 meets the corresponding actual size, while still ensuring the stability of the suspension of the bridge body 1.

[0046] Asbestos layers are provided on the side of each connecting plate 53 and the transverse plate 51 facing the bridge body 1, so that the asbestos layers fit the outer wall surface of the bridge body 1. The provision of the asbestos layers makes the bridge frame 5 fit the outer surface of the bridge body 1 and plays a certain insulating role.

[0047] The bridge body 1 has heat dissipation holes on its side plates close to the connecting plates 53. The heat dissipation holes reduce the heat energy generated by power on.

[0048] Both ends of each first slide groove 41 are provided with detachably connected plugs, which can prevent the slider 42 from sliding out of the slideway.
