Description

Technical Field

[0001] The present disclosure relates to the electrical field, and in particular to a prefabricated electrical room. Background Art

[0002] Prefabricated electrical room (E-House), also known as prefabricated substation, PowerHouse, PowerDistribution Center, etc., is a complete electrical room that can integrate all electrical equipment, such as: medium and low voltage switchgear, power transformers, protection and control systems, AC and DC auxiliary power supplies, HVAC and fire protection systems, etc. Prefabricated electrical room is a prefabricated walk-in modular steel structure outdoor box that can accommodate medium voltage (MV) and low voltage (LV) switchgear and auxiliary equipment. It can be skid-mounted or directly installed on a truck, which can achieve shorter on-site installation, commissioning and start-up time. It is a high-quality and efficient alternative to traditional on-site civil substations and electrical rooms (for example, concrete, brick buildings, etc.).

[0003] The design concept of the prefabricated electrical room is mainly reflected in its "prefabrication" and "modular" characteristics. The main goal of this design concept is to improve construction efficiency, reduce construction costs, and ensure the safety and reliability of equipment. The prefabricated electrical room adopts a prefabricated method, and the main parts of the equipment are completed in the factory and then transported to the site for installation. This method can greatly shorten the construction period, reduce the workload on site, and improve construction efficiency. At the same time, since systematic integration and debugging can be carried out during the prefabrication process, the quality and reliability of the equipment can also be guaranteed.

[0004] However, for this prefabrication method, since the entire prefabricated electrical room needs to be transported, its size and strength have certain requirements. In particular, as an important component of the prefabricated electrical room, the design of the air-conditioning system is often limited and troubled by transportation and repeated disassembly and assembly. In some existing technologies, the air-conditioning device is hung on the outside of the wall, resulting in exceeding the transportation size limit. Therefore, the air-conditioning device needs to be disassembled from the main body of the prefabricated electrical room and reassembled after being transported to the site, which greatly increases the intensity and complexity of the work.

[0005] Therefore, a prefabricated electrical room that does not require reinstallation is needed to solve these problems. Utility Model Content

[0006] The purpose of the present disclosure is to at least solve the shortcomings existing in the prior art. The present disclosure proposes a prefabricated electrical room, including an electrical room shell, having a plurality of shell walls to enclose an internal space, the shell wall having an inner surface facing the internal space and an outer surface facing the outside of the electrical room shell, at least one shell wall of the electrical room shell is provided with an air-conditioning accommodating hole penetrating the outer surface and the inner surface; an air-conditioning device, which is in conformity with the shape of the air-conditioning accommodating hole and is installed in the air-conditioning accommodating hole, so that only one exposed surface of the air-conditioning device is exposed to the external environment of the electrical room shell, and the exposed surface does not protrude from the outer surface of the shell wall provided with the corresponding air-conditioning accommodating hole.

[0007] For example, according to some embodiments of the present disclosure, a flange is fixed on the inner surface, the flange extends from the inner surface perpendicular to the inner surface, and the air conditioning device extends from the inner surface through the air conditioning accommodating hole and is fixedly supported on the flange.

[0008] For example, according to some embodiments of the present disclosure, an extension length of the flange perpendicular to the inner surface is less than or equal to a length of the air conditioning device extending from the inner surface.

[0009] For example, according to some embodiments of the present disclosure, the flange is arranged around the periphery of the air conditioner accommodating hole.

[0010] For example, according to some embodiments of the present disclosure, the shell wall is provided with a plurality of reinforcing beams spanning the outer surface and the inner surface, and the plurality of reinforcing beams surround the periphery of the air conditioner accommodating hole.

[0031] In order to make the purpose, scheme and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present disclosure. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0032] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0033] According to the prefabricated electrical room disclosed in the present invention, it includes an electrical room housing and an air conditioning device 2 installed in the electrical room housing. The electrical room housing may include a plurality of housing walls 8, and the plurality of housing walls 8 surround and form an internal space of the prefabricated electrical room. The internal space is used to set one or more electrical devices, such as but not limited to medium and low voltage switchgear, power transformers, protection and control systems, AC and DC auxiliary power supplies, and other devices. For example, the housing wall 8 has six pieces to form a prefabricated electrical room in the shape of a cuboid or a cube, or it can be any shape according to the needs, such as a pentagonal column, a hexagonal column, etc.

[0034] In particular, the multiple shell walls 8 can have different structures, properties, and materials. For example, the top shell wall 8 can have the characteristics of being more waterproof and lighter in weight, so it can be thinner, made of higher quality materials, and coated or provided with a waterproof layer, etc. For example, the bottom shell wall 8 can be made of a stronger material and have a larger wall thickness to ensure that it can support the weight of multiple internal devices and personnel without being damaged during use and transportation. In addition, the side shell wall 8 may need to have a moderate weight and moderate strength. For example, it can be a hollow plate structure with a moderate thickness (for example, the thickness is between the thickness of the top shell wall and the bottom shell wall, such as Figure 3 As shown). Further, the surface of the shell wall of the side portion can be set to a wave-shaped, sawtooth-shaped or other back-and-forth bending structure, such as Figure 1 As shown in the outer surface 82 of the panel, the strength thereof is further enhanced without excessively increasing the weight of the panel.

[0035] The side housing wall 8 may be provided with through holes, for example, a door hole for installing in and out of a prefabricated electrical room, a window hole for ventilation, or an air conditioning receiving hole for installing the air conditioning device 2. In particular, the housing wall 8 according to the present disclosure may include an inner surface 81 facing the internal space and an outer surface 82 facing the outside of the electrical room housing, and the through holes penetrate the inner surface 81 and the outer surface 82.

[0036] The air conditioning device 2 can be installed on the housing wall 8 through the air conditioning accommodating hole provided on the housing wall 8. For example, the size and shape of the air conditioning accommodating hole can be set according to the size and shape of the air conditioning device 2, so that the air conditioning accommodating hole matches the shape of the air conditioning device 2. The air conditioning accommodating hole can be set at a suitable position according to specific needs, such as at a higher position to facilitate the flow and circulation of air. Air conditioning accommodating holes can also be set on multiple housing walls 8, or multiple air conditioning accommodating holes can be set on one housing wall 8, and each air conditioning accommodating hole is provided with a corresponding air conditioning device 2, so as to be used to set multiple air conditioning devices.

[0037] According to the prefabricated electrical room of the present disclosure, only one surface (i.e., the exposed surface) of the air conditioning device is exposed to the external environment of the prefabricated electrical room, and in particular, the exposed surface does not protrude from the outer surface 82 of the shell wall 8 provided with the corresponding air conditioning accommodating hole, such as Figure 3 As shown. In the present application, not protruding from the outer surface 82 means not protruding from the outermost contour of the outer surface 82. For example, when the outer surface 82 is a plane, the outermost contour is the plane where the outer surface is located; when the outer surface 82 is wavy, the outermost contour is the set of points on the outer surface 82 that are farthest from the inner surface 81. As a result, the size of the prefabricated electrical room will not be increased due to the air conditioning device, and during transportation, the air conditioning device does not need to be disassembled and reinstalled after being transported to the site.

[0038] like Figure 1 As shown, in order to maintain a clean and dry environment inside the prefabricated electrical room, the air-conditioning water outlet pipe 4 of the air-conditioning device 2 may be arranged outside the prefabricated electrical room.

[0039] Furthermore, in order to increase the installation strength of the air conditioning device 2, a flange 5 may be fixedly provided on the inner surface 81 of the housing wall 8, such as Figure 2 The flange 5 can extend perpendicularly from the inner surface 81 to the inner surface 81, thereby supporting the portion of the air conditioning device 2 extending from the inner surface 81 to the air conditioning receiving hole. In particular, the air conditioning device 2 is fixedly supported on the flange 5 by a plurality of connecting members 7 (such as screws, rivets, welding parts, pins, etc.), thereby making the air conditioning device 2 firmly connected to the housing wall 8 without causing relative displacement.

[0040] The extension length of the flange 5 perpendicular to the inner surface 81 may be less than or equal to the length of the air conditioning device 2 extending from the inner surface 81, so as to provide enhanced support without occupying more space inside the prefabricated electrical room.

[0041] The flange 5 can be arranged at the bottom, top or side of the air conditioning device 2. In particular, it can also be arranged at the bottom, top or side of the air conditioning device 2. Figure 2 As shown, the periphery of the entire air conditioning receiving hole is arranged so that the entire air conditioning device 2 can be extended into the annular frame formed by the flange 5, so that the flange 5 can share more weight of the air conditioning device 2 and make the load distribution more uniform.

[0042] Since a relatively large air conditioning receiving hole is provided on the shell wall 8, the strength of the shell wall 8 is damaged, and the periphery of the air conditioning receiving hole is subjected to a relatively large load, which may exceed the upper limit of the strength of the shell wall 8, thereby causing safety and stability problems. Therefore, the shell wall 8 may be strengthened, especially the periphery of the air conditioning receiving hole. Specifically, for example, Figure 2 and Figure 3As shown, a plurality of reinforcing beams spanning the outer surface 82 and the inner surface 81, such as a longitudinal reinforcing beam 1 and a transverse reinforcing beam 3, may be arranged inside or on the shell wall 8. These reinforcing beams surround the periphery of the air-conditioning accommodating hole to enhance the strength of the peripheral portion of the air-conditioning accommodating hole, and by spanning the inner surface and the outer surface, the strength of the entire shell wall 8 is enhanced.

[0043] In particular, the longitudinal cross beam 1 can be arranged to span the height of the shell wall 8 to further enhance the strength of the shell wall in the height direction, which is beneficial to the support of the top shell wall 8. Since the load on the side shell wall 8 in the transverse direction is smaller than that in the longitudinal direction, two transverse reinforcement beams can be arranged between two parallel longitudinal reinforcement beams. Only arranging transverse reinforcement beams around the air conditioning receiving hole can save materials and reduce the weight of the entire shell wall 8.

[0044] The flange 5 can be fixed to the inner surface 81 and / or the longitudinal reinforcement beam 1 and the transverse reinforcement beam 3 by, for example, welding, screw connection, riveting, or other commonly used methods in the art.

[0045] Furthermore, the flange 5 may also be provided with reinforcing ribs 6 arranged at intervals along the peripheral direction of the air conditioner receiving hole and perpendicular to the inner surface, such as Figure 2 and Figure 3 As shown, the strength of the flange 5 is thereby enhanced so that it can bear a greater weight load.

[0046] The above-mentioned flange 5, longitudinal reinforcement beam 1, transverse reinforcement beam 3 and reinforcement rib 6 can be made of the same or different materials. For example, their respective materials can be selected from metal materials such as aluminum, copper, aluminum alloy, stainless steel, or polymer materials such as plastic, resin, carbon fiber, etc., and the present disclosure does not make any special restrictions.

[0047] It should be understood that the above description is intended to illustrate rather than limit. For example, the above embodiments (and / or aspects thereof) can be used in combination with each other.
