Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural view of an embodiment of a prefabricated cabin provided in the present invention. As shown in fig. 1, the prefabricated cabin 10 includes a line collecting groove 11, a first ground structure 12, and a second ground structure 13. The prefabricated cabin 10 comprises a wire collecting groove 11, a first grounding structure 12 and a second grounding structure 13, which are all positioned below the floor of the prefabricated cabin, wherein the wire collecting groove 11 is used for collecting wires (including various wires with strong and weak electricity) in the prefabricated cabin 10. The first grounding structure 12 is used for grounding the weak current ground wire in the wire collecting groove 11; the second grounding structure 13 is used for grounding the strong electric ground wire in the wire collecting slot 11. The wire collecting groove 11 includes a wire groove 111 and a wire collecting box 112. The junction box 112 is located inside the lengthwise extension of the wiring duct 111, i.e., inside the long side of the prefabricated compartment 10.
Referring to fig. 2 in combination, fig. 2 is a schematic structural diagram of a trunking in an embodiment of the prefabricated cabin according to the present invention. As can be seen from fig. 2, the wiring groove 111 has a plurality of wiring holes 1111, and the junction box 112 is located at intervals between the wiring holes 1111. Thus, the grounding wires (including the strong current grounding wire and the weak current grounding wire) of the equipment corresponding to the wire concentration box 112 can enter the wire concentration box 112 from the wire routing hole 1111 on one side of the wire concentration box 112 and extend out from the wire routing hole on the other side of the wire concentration box 112 to be connected with the first grounding structure 12 or the second grounding structure 1. In addition, in the present embodiment, the cross section of the wiring groove 111 is , which helps to limit various wires (including ground wires and connection wires for power supply, signals, etc.) of the device to the wiring groove 111 without scattering. In other implementations, the wiring slots 111 may also be C-shaped or otherwise configured with a wire harness function to facilitate the organization of the various wires within the prefabricated cabins 10.
The cluster box 112 is used to house excess lengths of ground wires (including both strong and weak electrical ground wires) for equipment in the prefabricated cabins 10. Since it can be seen from fig. 1 that the spacing between the line collecting groove 11 and the first and second ground structures 12, 13 is not far, i.e. the length of the ground line in the line collecting groove 11 required to be connected to the first or second ground structure 12, 13 is short. In actual operation, the length of the grounding wire far exceeds the required length, and in order to facilitate the arrangement of the wires, the wires with excessive lengths are placed in the wire concentration box 112, so that the wiring of the prefabricated cabin 10 is neat, and the subsequent overhaul is also convenient.
Referring to fig. 3 in combination, fig. 3 is a schematic structural view of the prefabricated compartment of fig. 1 in a cross-section A-A'. As can be seen from fig. 3, the prefabricated cabin 10 further comprises a first support frame 14 and a second support frame 15. The first support frame 14 is disposed on the ground, and is used for supporting the first grounding structure 12 and adjusting the height of the first grounding structure 12 to be consistent with the height of the line collecting groove 11. The second supporting frame 15 is disposed on the ground, and is used for supporting the second grounding structure 13 and adjusting the height of the second grounding structure 13 to be consistent with the height of the line collecting slot 11. Further, as shown in fig. 3, the cross-sectional area of the first ground structure 12 is smaller than the cross-sectional area of the second ground structure 13. Because the second grounding structure 13 is connected to a strong electric ground, the wider cross-sectional area can help to prevent the second grounding structure 13 from being broken down by high voltage, improving its reliability and service life. In this embodiment, the material of the line collecting groove 11 is steel, the material of the first grounding structure 12 is copper, and the material of the second grounding structure 13 is steel. In other implementations, the materials of the first and second ground structures 12 and 13 may be any other metal. The line collecting groove 11 can also be made of other materials such as plastics, concrete and the like.
Referring to fig. 4 in combination, fig. 4 is a schematic structural view of a second grounding structure and a second supporting frame in an embodiment of the prefabricated cabin provided by the present invention. As shown in fig. 4, the second support 15 has a Z-shaped structure, one end of which is used for grounding, and one end of which is connected to the second grounding structure 13 by means of a bolt lock, and in other embodiments, the second support 15 and the second grounding structure 13 may be connected by other means, such as welding, riveting, or integrally forming. In this embodiment, the second support 15 is directly connected to the ground at one end for grounding, and in other embodiments, may be connected to another grounded conductor, so as to achieve the purpose of grounding, for example, a steel foundation structure in which the prefabricated cabin 10 is inserted into the ground may be connected. In this embodiment, the second grounding structure 13 and the second supporting frame 15 are also used to support the prefabricated cabin 10 because they are located at the bottom of the prefabricated cabin. In other embodiments, it is also possible that the first grounding structure 12 and the first support frame 14 together with the second grounding structure 13 and the second support frame 15 are used for supporting the prefabricated cabin.
The second grounding structure 13 is distributed with a plurality of connecting holes 131, the connecting holes 131 are used for connecting a grounding wire (including a strong current grounding wire and a weak current grounding wire), and the grounding wire can be connected with the second grounding structure 13 by penetrating a metal wire core of the grounding wire through the connecting holes 131 in a welding manner or fixedly connected through a fixing piece. In this embodiment, the connection holes 131 are uniformly distributed, and in other embodiments, the connection holes 131 may be non-uniformly distributed according to actual needs. In this embodiment, the connecting holes 131 are uniformly sized, and in other embodiments, the connecting holes 131 may be sized according to actual needs. For example, in a region where some or some of the ground lines (including the strong current ground line and the weak current ground line) are densely distributed, the distribution of the connection holes 131 is correspondingly dense, and the connection holes are also larger.
The structures of the first grounding structure 12 and the first supporting frame 14 are substantially similar to those of the second grounding structure 13 and the second supporting frame 15, and the details thereof are not repeated herein.
Referring to fig. 1 again, as shown in fig. 1, the first grounding structure 12 and the second grounding structure 13 are both distributed on the outer side of the trunking 11 in the length direction, i.e. in the direction of the long side of the prefabricated cabin 10, and the space between the outer edge of the prefabricated cabin 10 and the trunking 11. In this embodiment, the first grounding structure 12 is closer to the line collecting groove 11, and in other embodiments, the second grounding structure 13 may be closer to the line collecting groove 11.
The first grounding structure 12 and the second grounding structure 13 correspond to the position distribution of at least two devices in the prefabricated cabin 10, and in this embodiment, the first grounding structure 12 and the second grounding structure 13 correspond to the distribution of all devices in the prefabricated cabin, and are therefore two continuous metal plates, and in consideration of the operability of actual use, the first grounding structure 12 and the second grounding structure 13 may be a plurality of strip-shaped metal plates as shown in fig. 4, which are spliced end to end.
In this embodiment, the prefabricated cabin 10 is provided with a plurality of devices on both long sides, so that the line collecting grooves 11 are distributed under the floor inside the two long sides of the prefabricated cabin 10. In other embodiments, for example, the prefabricated cabins 10 are provided with a plurality of devices on only one long side, and the line-collecting grooves 11 are correspondingly distributed under the floor on the inner side of the long side. In this embodiment, each hub 112 is disposed corresponding to one device in the prefabricated cabin 10, and is used for collecting the electric wires of the device, and in other embodiments, the area of the hub 112 may be enlarged, so that one hub 112 may correspond to a plurality of devices. In this embodiment, the wire-collecting box 112 and the wire-distributing groove 111 are relatively fixed, and the wire-collecting boxes 112 are uniformly distributed along the wire-distributing groove 111. In other implementation scenarios, the hub 112 and the wiring groove 111 are movably disposed, such as a buckle, or a bolt lock, etc., and whether the hub 112 needs to be installed in this place can be determined according to whether there is a requirement for the hub in the actual situation. The hub 112 may be unevenly disposed, but disposed according to whether or not there is a demand for the hub.
In this embodiment, the first grounding structures 12 are distributed on three sides (including two long sides and one short side) of the prefabricated cabin 10, and the second grounding structures 13 are distributed on three sides (including two long sides and one short side) of the prefabricated cabin 10. In other implementation scenarios, the first grounding structure 12 and the second grounding structure 13 may be distributed according to actual needs, for example, may be distributed on only one side of the prefabricated cabin 10, or may be directly distributed on four sides.
In practical use, a plurality of prefabricated cabins 10 may be required to be used to meet the use requirement, and the plurality of prefabricated cabins 10 need to be connected through various wires to provide power (strong electric wires) or transmit signals (weak electric wires), etc., so as to reduce interference between different wires, in this embodiment, the weak electric power transmission lines and the strong electric power transmission lines are respectively led out from the bottom ends of different sides of the prefabricated cabins 10. For example, when the weak current power line is outputted from the bottom side of the prefabricated compartment 10 where the long side is located, the strong current power line is outputted from the bottom side of the prefabricated compartment 10 where the short side is located.
Referring again to fig. 3, the prefabricated cabin 10 is further provided with an outer edge steel frame 21 which is identical to the wiring groove 111 in structure but is arranged opposite to the first grounding structure 12, the section of the outer edge steel frame 21 is , and an area 211 which is left between the outer edge steel frame 21 and one side, far away from the ground, of the wiring groove 111 is used for placing equipment in the prefabricated cabin 10, so that the equipment is closer to the first grounding structure 12 and the second grounding structure 13, and wiring layout of various grounding wires of the equipment is more convenient. In addition, the antistatic floor 30 is arranged on the inner side of one end, far away from the ground, of the line collecting groove 11, so that electromagnetic radiation on two sides of the antistatic floor 30 can be effectively isolated, and electromagnetic interference between the first grounding structure 12, the second grounding structure 13 and equipment is reduced. Further, a water-blocking layer 31 may be provided between the antistatic floor 30 and the line collecting groove 11, and it is possible to prevent moisture on the surface of the antistatic floor 30 from being conducted to parts located under the antistatic floor 30, such as the first and second ground structures 12 and 13, to cause a short circuit therebetween or corrosion of the parts. In a general application scenario, the prefabricated cabin 10 includes a plurality of antistatic floors 30, and a water-proof layer 31 is disposed between every two antistatic floors 30 to protect parts located under the antistatic floors 30 and prolong the service life of the prefabricated cabin 10.
As can be seen from the above description, the present embodiment reduces the interference between the first and second grounding structures by providing the first and second grounding structures respectively, so that the strong and weak electric grounds are separated. The first grounding structure and the second grounding structure can correspond to a plurality of devices in the prefabricated cabin, so that the complexity of grounding operation can be simplified, and the construction time is saved. Adopt the line concentration groove structure, arrange the planning with the electric wire, convenient maintenance.
