Description

Technical Field

[0001] This utility model relates to the field of busbar trunking, and in particular to a shock-resistant and impact-resistant busbar trunking. Background Technology

[0002] Busbar trunking is a closed conductive system used for transmitting and distributing large currents, and for centralized distribution of electrical energy. It mainly consists of conductors, insulating materials, a metal trunking, connectors, and supports. The conductors are typically made of copper or aluminum; the insulating materials support and protect the conductors; the metal trunking provides enclosure and protection; the connectors connect different sections of the busbar trunking; and the supports secure the busbar trunking, ensuring its stability.

[0003] When a power source is connected to one end of the busbar trunking, current is transmitted through the conductors within the trunking. Relying on the conductors' excellent conductivity, electrical energy is delivered from the power source to each load end. Simultaneously, insulating material separates conductors at different potentials, preventing current leakage and short circuits, thus ensuring the electrical safety of the busbar trunking during operation.

[0004] Busbar trunking also features a grounding system to ensure that in the event of a leakage or other fault during operation, the current is conducted to the earth, protecting personnel and equipment. Application number CN202323280540.3 discloses a shock-absorbing structure and seismic-resistant busbar trunking, incorporating springs and rubber plates to improve its seismic resistance. However, this device has poor applicability; it can only provide fixed shock absorption and pressure resistance for busbar trunking of a specific size, and cannot be well adapted to busbar trunking of different sizes, resulting in poor practicality.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of an anti-seismic and impact-resistant busbar trunking provided by this utility model; Figure 2 for Figure 1 A structural schematic diagram of the front view of the protective outer casing shown; Figure 3 for Figure 1 A structural schematic diagram of the right-side cross-sectional view of the protective outer casing shown; Figure 4 for Figure 1 The diagram shows a front view of the main body of the busbar trunking. A shock-resistant and impact-resistant busbar trunking includes: a protective shell 1, a shock-resistant component 2 provided at the bottom of the inner wall of the protective shell 1, and a fixing component 3 provided at the top of the inner wall of the protective shell 1.

[0024] The seismic component 2 includes a damper 21 disposed at the bottom of the inner wall of the protective shell 1, a support platform 22 disposed at the top of the damper 21, a sliding plate 23 fixedly disposed at the top of the support platform 22, and the left and right sides of the sliding plate 23 being slidably connected to the inner wall of the protective shell 1.

[0025] By setting up the damper 21, the impact of vibration on the busbar trunking can be reduced to a certain extent. At the same time, since the protective housing 1 is located on the outside of the busbar trunking, the busbar trunking can achieve better impact resistance.

[0026] The fixing component 3 includes a clamping plate 31 that can slide left and right and is mirrored on the top of the sliding plate 23. A busbar body 32 is provided on one side of the two clamping plates 31 opposite each other and on the top of the sliding plate 23.

[0027] The inner side of the sliding plate 23 is rotatably provided with a bidirectional threaded rod 33. The peripheral side of the bidirectional threaded rod 33 is threadedly connected to the bottom of the two clamping plates 31. The right end of the bidirectional threaded rod 33 passes through the inner side of the sliding plate 23 and extends to the right side of the protective shell 1. A handwheel 34 is provided at the right end of the bidirectional threaded rod 33.

[0028] By rotating the handwheel 34, the bidirectional threaded rod 33 is rotated, which in turn causes the two clamping plates 31 to move relative to each other, thereby fixing the left and right positions of the busbar trunking body 32.

[0029] The fixing component 3 also includes a guide rod 35 disposed on the top of the protective housing 1. The bottom end of the guide rod 35 penetrates the top of the protective housing 1 and extends to its inner side. A pressing plate 36 is disposed at the bottom end of the guide rod 35 and located inside the protective housing 1. The bottom of the pressing plate 36 is in close contact with the top of the busbar trunking body 32.

[0030] With the pressing spring 37 in place, the pressing plate 36 and the guide rod 35 will move downwards and press down inside the protective housing 1, and finally abut against the top of the busbar trunking body 32, thereby fixing the busbar trunking body 32 in the vertical direction.

[0031] A pressing spring 37 is provided on the top of the protective housing 1 and on the periphery of the guide rod 35. The top of the pressing spring 37 is fixedly connected to the top of the guide rod 35. A handle 38 is provided on the top of the pressing plate 36 and above the protective housing 1.

[0032] When disassembly is required, the handle 38 can be pulled to raise the pressing plate 36, thereby removing the fixation of the busbar trunking body 32.

[0033] The seismic component 2 also includes a connecting rod 24 longitudinally disposed at the bottom of the inner wall of the protective shell 1. Two connecting blocks 25 are disposed on the peripheral side of the connecting rod 24, which can slide back and forth along its length. A connecting plate 26 is rotatably disposed on the top of the two connecting blocks 25. The tops of the two connecting plates 26 are respectively rotatably connected to the left and right sides of the top of the damper 21. Two buffer springs 27 are disposed on the peripheral side of the connecting rod 24. The ends of the two buffer springs 27 that are close to each other are respectively fixed to the opposite sides of the two connecting blocks 25.

[0034] The buffer spring 27, connecting block 25 and connecting plate 26 are designed to further assist the damper 21 in reducing and offsetting vibrations.

[0035] An air inlet 4 is provided on the top right side of the protective shell 1, and a cooling fan 5 is provided on the top left side of the protective shell 1.

[0036] The air inlet 4 and cooling fan 5 ensure the heat dissipation of the busbar trunking body 32.

[0037] The working principle of the earthquake-resistant and impact-resistant busbar trunking provided by this utility model is as follows:

[0038] Step 1: When in use, remove the cover plate on the top of the protective housing 1, place the busbar trunking body 32 on the top of the sliding plate 23, and then rotate the handwheel 34 to drive the bidirectional threaded rod 33 to rotate, thereby driving the relative movement of the two clamping plates 31, thereby fixing the left and right positions of the busbar trunking body 32. After installing the cover plate of the protective housing 1, under the action of the pressing spring 37, the pressing plate 36 will abut against the top of the busbar trunking body 32, thereby fixing the busbar trunking of different sizes and models.

[0039] Step 2: When the busbar trunking body 32 is subjected to external vibration or impact, the protective shell 1 will protect against the impact and prevent it from directly affecting the busbar trunking body 32. At the same time, through the setting of the damper 21, buffer spring 27, connecting block 25 and connecting plate 26, the impact of vibration on the busbar trunking can be reduced to a certain extent.

[0040] Compared with related technologies, the shock-resistant and impact-resistant busbar trunking provided by this utility model has the following beneficial effects:

[0041] By placing the busbar trunking body 32 on top of the sliding plate 23, and then rotating the handwheel 34 to drive the bidirectional threaded rod 33 to rotate, thereby driving the relative movement of the two clamping plates 31, the left and right positions of the busbar trunking body 32 are fixed. After the cover plate is installed, under the action of the pressing spring 37, the pressing plate 36 will abut against the top of the busbar trunking body 32, thereby meeting the shock absorption requirements of busbar trunking of different sizes.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
