Description

Technical Field

[0001] The present invention relates to the technical field of bus ducts, and specifically to a modularly spliced bus duct. Background Art

[0002] A bus duct is a closed metal device composed of copper or aluminum busbars, used to distribute relatively high power to each component of a decentralized system. It has increasingly replaced wire and cable in indoor low-voltage power transmission trunk line engineering projects;

[0003] However, since the bus duct itself is in a closed state, the heat of the bus duct cannot be effectively and quickly released, which will cause certain failures of the bus duct over time. At the same time, when the existing plug-in box is connected to the bus duct, it only relies on the connection head of the plug-in box, and the connection relationship between the plug-in box and the bus duct is not firm. Therefore, after long-term use, the connection of the plug-in box will become unstable. Summary of the Invention

[0004] The purpose of the present invention is to provide a modularly spliced bus duct to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A modularly spliced bus duct includes a bus duct main body and a controller. The bus duct main body includes a housing. An insertion box is installed outside the housing. A plurality of heat dissipation components are respectively installed on the sides of the housing. The heat dissipation components are installed on both sides of the bus duct main body. Two detection components are installed on the bus duct main body. The two detection components are respectively installed at the input end and the output end of the bus duct. The detection components cooperate with the heat dissipation components. The heat dissipation components can dissipate heat from the area with heavy heat generation, and the detection components can monitor whether the current bus duct main body is stable.

[0006] Further, a plurality of limiting grooves are respectively opened on both sides of the bus duct main body. The heat dissipation components are respectively installed inside the plurality of limiting grooves. The heat dissipation components include a heat conduction component. A plurality of shape memory alloy wires are installed inside the limiting grooves. The heat conduction component is slidably installed in the limiting groove. Both sides of the heat conduction component are respectively connected to the shape memory alloy wires, and the other ends of the shape memory alloy wires are connected to the limiting grooves.

[0007] Further, the heat conduction component includes a heat conduction plate and a plurality of heat conduction fins. A plurality of the heat conduction fins are installed on the heat conduction plate. The bottom of the heat conduction fins cooperates with the upper and lower sliding grooves of the limiting groove. The heat conduction plate contacts the outer wall of the limiting groove. The heat conduction plate can transfer the heat of the bus duct main body to the heat conduction fins.

[0008] Further, when the shape memory alloy wire is heated: the heated shape memory alloy wire will expand and contract, and at the same time pull the heat conduction component;

[0009] When the temperature of the shape memory wire is constant: the shape memory wire remains unchanged, and the heat conduction component is located between the two groups of shape memory wires.

[0010] Furthermore, an installation groove is formed on the main body of the busbar trunking. The plug-in box is installed outside the installation groove, and a plug connector is arranged outside the plug-in box. The plug connector is matched with the installation groove. A wiring device is installed inside the plug-in box, and the wiring device is connected to the plug connector.

[0011] Furthermore, two clamping components are installed at the bottom of the plug-in box. The two clamping components are respectively installed at both ends of the plug-in box. The clamping component includes a transmission rod, a turning handle, two limiting rods and two clamping blocks. Two different-direction threads are respectively arranged at both ends of the transmission rod. The transmission rod is installed between the plug-in boxes. A turning handle is installed at one end of the transmission rod. The limiting rods are respectively installed on two outer sides of the plug-in box. The limiting rods are parallel to the transmission rod, and the clamping blocks are installed on the limiting rods and the transmission rod.

[0012] Furthermore, when the turning handle is rotated forward: the transmission rod can drive the clamping block to clamp the outer shell;

[0013] When the turning handle is rotated reversely: the transmission rod can drive the clamping block to release the clamping of the outer shell.

[0014] Furthermore, the material of the outer shell is a magnetic interference-resistant material. An insulating board and a fireproof cotton are arranged in the interlayer of the outer shell, and a plurality of heat dissipation grooves are arranged on the outer shell.

[0015] Furthermore, the detection component includes a distance measuring sensor, and the distance measuring sensor is matched with the heat conduction fin;

[0016] When the heat conduction component is in the middle of the limiting groove: the voltage of the current busbar trunking main body is stable;

[0017] When the heat conduction component reciprocates in the limiting groove: the voltage of the current busbar trunking main body is in an unstable state.

[0018] Furthermore, the controller is installed outside the housing. The controller is connected to the plug-in box, and an operation panel is arranged outside the controller.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Therefore, when the device is in use, the heat dissipation of the busbar trunking main body can be exported through the heat dissipation component and the heat conduction component, the heat dissipation of the busbar trunking main body is accelerated, and the temperature of the busbar trunking main body can always be maintained in a relatively stable state;

[0021] 2. When the plug-in box of the device is connected to the main body of the busbar trunking, the plug-in box can reinforce the connection relationship between the plug-in box and the main body of the busbar trunking through the clamping component. During specific use, the staff only needs to rotate the turning handle forward, and then drive the transmission rod to rotate forward together. When the transmission rod rotates forward, it will drive the clamping block to move, so that the clamping block can clamp the outer shell, thereby reinforcing the connection relationship between the plug-in box and the main body of the busbar trunking. When the staff rotates the turning handle in reverse, the clamping block can be separated from the outer shell, so that the clamping component releases the outer shell, and then the plug-in box and the main body of the busbar trunking can be separated after that;

[0022] 3. The detection component can detect whether the voltage of the main body of the busbar trunking is normal. During specific use, the distance measuring sensor can detect the distance of the heat conduction fin. When the heat conduction component is in the middle of the limit groove, it means that the voltage of the current main body of the busbar trunking is relatively stable. When the main body of the busbar trunking is in a stable state for a long time, the distance measuring sensor will detect that the heat conduction component gradually approaches the detection component, and this situation can also indicate that the main body of the busbar trunking is in a stable state. When the heat conduction component reciprocates in the limit groove, it means that the voltage of the current main body of the busbar trunking is unstable. Description of the Drawings

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example: Figures 1-6 As shown, the present invention provides a modular splicing bus duct technical solution, including a bus duct body 1 and a controller 7, the bus duct body 1 includes a shell 11, a plug-in box 2 is installed on the outside of the shell 11, and multiple groups of heat dissipation components 3 are installed on the sides of the shell 11, and the heat dissipation components 3 are installed on both sides of the bus duct body 1. Two groups of detection components 4 are installed on the bus duct body 1, and the two groups of detection components 4 are installed at the input end and the output end of the bus duct respectively. The detection component 4 cooperates with the heat dissipation component 3, and the heat dissipation component 3 can dissipate heat to the focused heating area, and the detection component 4 can monitor whether the current bus duct body 1 is stable;

[0032] First, a bus duct body 1 of a specific length needs to be manufactured according to the requirements. After that, when the device is in use, the plug-in box 2 needs to be connected to the bus duct body 1. Then, the connection between the plug-in box 2 and the bus duct body 1 is reinforced through the clamping component 6 at the bottom of the plug-in box 2, so that the two can be more closely connected together to prevent the plug-in box 2 and the bus duct body 1 from being separated due to long-term use. After that, the staff can install the bus duct body 1 at the required position according to the requirements. When the bus duct body 1 is in specific use, the heat dissipation component 3 of the device can continuously heat the bus duct body 1. To dissipate heat, because the bus duct body 1 transmits high-voltage current when in use, the bus duct body 1 will generate high temperature after long-term use, but the simple heat dissipation holes cannot effectively discharge the heat. The device can effectively export the heat through the heat dissipation component 3. At the same time, the heat dissipation component 3 can also change its own position according to the different heating points, so that the heat dissipation component 3 can accurately conduct heat and dissipate heat to the heat source. At the same time, during the operation of the heat dissipation component 3, the detection component 4 of the device can combine the status of the heat dissipation component 3 to judge the stability of the current bus duct.

[0033] like Figures 1-2 and Figure 4As shown in the figure, in this embodiment, specifically, a plurality of sets of limiting grooves 111 are respectively formed on both sides of the busbar trunking body 1, and the heat dissipation assemblies 3 are respectively installed inside the plurality of sets of limiting grooves 111. The heat dissipation assembly 3 includes a heat conduction assembly 5. A plurality of shape memory alloy wires 31 are installed inside the limiting groove 111. The heat conduction assembly 5 is slidably installed in the limiting groove 111. Both side surfaces of the heat conduction assembly 5 are respectively connected to the shape memory alloy wires 31, and the other ends of the shape memory alloy wires 31 are connected to the limiting groove 111;

[0034] When the heat dissipation assembly 3 of the device is in use, it can accelerate the release of heat by the busbar trunking body 1. When the heat dissipation assembly 3 is specifically in use, the shape memory alloy wires 31 can pull the heat conduction assembly 5 to move in the limiting groove 111. Because the shape memory alloy wires 31 are relatively close to the busbar trunking body 1, the heat will first act on the shape memory alloy wires 31. When the shape memory alloy wires 31 are heated, the shape memory alloy wires 31 will expand and contract. Then, when a set of shape memory alloy wires 31 contracts, it will pull the heat conduction assembly 5 together, so that the heat conduction assembly 5 can move in the limiting groove 111. By continuously contracting, the heat conduction assembly 5 will move to the heat source, and then the heat of the busbar trunking body 1 will be conducted from the inside to the outside through the heat conduction assembly 5, thus achieving the effect of temperature reduction.

[0035] As Figure 4 shown in the figure, in this embodiment, specifically, the heat conduction assembly 5 includes a heat conduction plate 51 and a plurality of heat conduction fins 52. A plurality of the heat conduction fins 52 are installed on the heat conduction plate 51. The bottom of the heat conduction fins 52 is matched with the upper and lower sliding grooves of the limiting groove 111. The heat conduction plate 51 is in contact with the outer wall of the limiting groove 111. The heat conduction plate 51 can transfer the heat of the busbar trunking body 1 to the heat conduction fins 52;

[0036] When the heat conduction assembly 5 of the device is in use, it can conduct the heat of the busbar trunking body 1 from the inside to the outside, thus achieving the effect of temperature reduction. When the heat conduction assembly 5 is specifically in use, the heat conduction plate 51 will move inside the limiting groove 111 under the drive of the shape memory alloy wires 31. During the movement of the heat conduction plate 51, it will drive together. And because the heat conduction plate 51 is in contact with the limiting groove 111, when the heat is conducted out from the housing 11, it will first be conducted by the heat conduction plate 51, and then the heat will be conducted to the heat conduction fins 52. The heat conduction fins 52 have a large area in the air and are provided with a plurality of heat conduction fins 52, so as to accelerate the heat dissipation effect of the device.

[0037] As Figures 1-2 shown in the figure, in this embodiment, specifically, when the shape memory alloy wires 31 are heated: the heated shape memory alloy wires 31 will expand and contract, and at the same time pull the heat conduction assembly 5;

[0038] When the temperature of the shape memory wire 31 is constant: the shape memory wire 31 remains unchanged, and the heat conduction component 5 is located between the two shape memory wires 31;

[0039] When the device is in use, due to the high-voltage current transmitted by the busbar trunking, it will generate a certain amount of heat by itself, and the heat is always locked inside the busbar trunking. If relying solely on its own heat dissipation, the effect is relatively low. Through the heat dissipation component 3, the heat dissipation speed can be accelerated. The heat dissipation component 3 is powered by the shape memory wire 31, and the shape memory wire 31 contracts due to the heat conducted on the housing 11. Then, when the shape memory wire 31 expands and contracts, it will pull the heat dissipation component 3 to move together. Thus, the heat dissipation component 3 can precisely dissipate heat to the area with heavy heat generation. When the temperatures received by the two shape memory wires 31 are similar, the two shape memory wires 31 contract simultaneously, but the position of the heat conduction component 5 may not change. When the heat conduction component 5 remains unchanged in the middle position, the heat at the output end will slowly decrease. Then, the heat received by the shape memory wire 31 at the input end will be greater than the heat received by the shape memory wire 31 at the output end. Thus, the heat conduction component 5 will move towards the input end again to conduct heat.

[0040] As Figures 1-3 shown, in this embodiment, specifically, an installation groove 12 is formed on the busbar trunking body 1, the plug-in box 2 is installed outside the installation groove 12, a plug 21 is arranged outside the plug-in box 2, the plug 21 is matched with the installation groove 12, and a wiring device 22 is installed inside the plug-in box 2, and the wiring device 22 is connected to the plug 21; The plug-in box 2 is an electrical connection device mainly used for insertion and extraction operations in a circuit. At the same time, the plug-in box 2 is used to connect electrical equipment and cables. It provides a convenient and fast way to connect and disconnect the circuit, making the installation and maintenance of electrical equipment simpler. During specific use, first, the plug 21 outside the plug-in box 2 is connected to the installation groove 12 on the busbar trunking body 1, and the wiring device 22 is used to assist in connecting external electrical equipment or cables to the plug-in box 2, thereby facilitating the power-off of the electrical equipment or cables connected thereto and facilitating subsequent maintenance work.

[0042] As Figure 1 、 Figure 3 and Figure 5As shown, in this embodiment, specifically, two sets of clamping components 6 are installed at the bottom of the plug-in box 2. The two sets of clamping components 6 are respectively installed at both ends of the plug-in box 2. The clamping component 6 includes a transmission rod 61, a turning handle 62, two sets of limiting rods 63 and two sets of clamping blocks 64. Two different-direction threads are respectively arranged at both ends of the transmission rod 61. The transmission rod 61 is installed between the plug-in boxes 2. A turning handle 62 is installed at one end of the transmission rod 61. Two limiting rods 63 are respectively installed on the two outer sides of the plug-in box 2. The limiting rods 63 are parallel to the transmission rod 61. Clamping blocks 64 are installed on the limiting rods 63 and the transmission rod 61.

[0043] When the plug-in box 2 of the device is in use, it can not only be fixed by connecting the plug connector 21 with the installation groove 12, but also the connection relationship between the plug-in box 2 and the busbar trunk 1 can be strengthened through the clamping component 6. When the clamping component 6 is specifically in use, after the plug connector 21 is connected with the installation groove 12, the staff can rotate the turning handle 62. When the turning handle 62 rotates, it will drive the transmission rod 61 to rotate. Then, when the transmission rod 61 rotates, it will drive the clamping blocks 64 on both sides to clamp the busbar trunk 1. During the movement of the clamping blocks 64, the limiting rods 63 can limit the clamping blocks 64, enabling the clamping blocks 64 to move horizontally, so that the clamping blocks 64 can move stably, and then clamp the outer shell, thereby making the connection between the plug-in box 2 and the busbar trunk 1 more stable. When the staff reverses the turning handle 62, the clamping blocks 64 can move in the opposite direction, and then the clamping blocks 64 release the outer shell. After that, the plug-in box 2 can be separated from the busbar trunk 1.

[0044] As Figure 5 shown, in this embodiment, specifically, when the turning handle 62 rotates forward: the transmission rod 61 can drive the clamping blocks 64 to clamp the outer shell;

[0045] When the turning handle 62 rotates in reverse: the transmission rod 61 can drive the clamping blocks 64 to release the clamping of the outer shell;

[0046] When the device needs to clamp and reinforce the outer shell, the staff only needs to rotate the turning handle 62 forward, and then drive the transmission rod 61 to rotate forward together. When the transmission rod 61 rotates forward, it will drive the clamping blocks 64 to move, so that the clamping blocks 64 can clamp the outer shell, thereby strengthening the connection relationship between the plug-in box 2 and the busbar trunk 1. When the staff reverses the turning handle 62, the clamping blocks 64 can be separated from the outer shell, and then the clamping component 6 releases the outer shell. After that, the plug-in box 2 can be separated from the busbar trunk 1.

[0047] As Figures 1-2As shown in the figure, in this embodiment, specifically, the housing is made of a magnetic interference-resistant material. An insulating board and fireproof cotton are arranged inside the housing sandwich, and multiple groups of heat dissipation grooves are arranged on the housing.

[0048] Since the housing is made of a magnetic interference-resistant material, it can prevent the external magnetic field from affecting the busbar trunking. The insulating board and fireproof cotton can effectively protect the busbar trunking body 1, and the heat dissipation grooves on the housing can export heat more quickly.

[0049] As Figures 1-2 and Figure 6 As shown in the figure, in this embodiment, specifically, the detection component 4 includes a distance sensor 41, and the distance sensor 41 cooperates with the heat conduction fin 52.

[0050] When the heat conduction component 5 is in the middle of the limit groove 111: the voltage of the current busbar trunking body 1 is stable;

[0051] When the heat conduction component 5 reciprocates in the limit groove 111: the voltage of the current busbar trunking body 1 is in an unstable state;

[0052] Therefore, when the device is in use, the detection component 4 can detect whether the voltage of the busbar trunking body 1 is normal. Specifically, when in use, the distance sensor 41 can detect the distance of the heat conduction fin 52. When the heat conduction component 5 is in the middle of the limit groove 111, it means that the voltage of the current busbar trunking body 1 is relatively stable. When the busbar trunking body 1 is in a stable state for a long time, the distance sensor 41 will detect that the heat conduction component 5 gradually approaches the detection component 4, and this situation can also indicate that the busbar trunking body 1 is in a stable state. When the heat conduction component 5 reciprocates in the limit groove 111, it means that the voltage of the current busbar trunking body 1 is unstable.

[0053] As Figures 1-2 As shown in the figure, in this embodiment, specifically, the controller 7 is installed outside the housing 11. The controller 7 is connected to the plug-in box 2, and an operation panel is arranged outside the controller 7.

[0054] When the device is in use, it can monitor the busbar trunking body 1 through the operation panel, which is convenient for the staff to monitor the busbar trunking body 1.

[0055] Working principle: First, a bus duct body 1 of a specific length needs to be manufactured according to the needs. After that, when the device is used, the plug-in box 2 needs to be connected to the bus duct body 1. Then, the connection relationship between the plug-in box 2 and the bus duct body 1 is reinforced through the clamping component 6 at the bottom of the plug-in box 2, so that the two can be more closely connected together to prevent the plug-in box 2 and the bus duct body 1 from being separated due to long-term use. After that, the staff can install the bus duct body 1 at the required position according to the needs. When the bus duct body 1 is in specific use, the heat dissipation component 3 of the device can continuously heat the bus duct body 1. The bus duct body 1 is used to dissipate heat, because the bus duct body 1 transmits high-voltage current when in use. After long-term use, the bus duct body 1 will generate high temperature, but the simple heat dissipation holes cannot effectively discharge the heat. The device can effectively export the heat through the heat dissipation component 3. At the same time, the heat dissipation component 3 can also change its own position according to the different heating points, so that the heat dissipation component 3 can accurately conduct heat and dissipate heat to the heat source. At the same time, during the operation of the heat dissipation component 3, the detection component 4 of the device can combine the status of the heat dissipation component 3 to judge the stability of the current bus duct.

[0056] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
