Description

Technical Field

[0001] This utility model belongs to the field of power transmission engineering technology, and in particular relates to a fixed structure for power distribution cabinets in power transmission engineering. Background Technology

[0002] Outdoor distribution cabinets play a crucial role in power transmission projects. As an important component of the power system, they are primarily used for the distribution, control, and protection of electrical energy, ensuring stable power transmission and safe operation. Distribution cabinets effectively convert the electrical energy from high-voltage transmission lines into voltage levels suitable for end users, while also providing multiple protection functions such as lightning strike protection, short circuit protection, and overload protection, thus improving the reliability of the transmission system. They play an irreplaceable role in various fields, including urban power grids, industrial parks, new energy power generation, and rural power grid transformation.

[0003] Currently, in power transmission projects, outdoor distribution cabinets are commonly installed using concrete pedestals. However, this method has several drawbacks. First, it is difficult to construct and has low installation efficiency. The construction process of concrete pedestals typically involves multiple steps, including earthwork excavation, formwork erection, rebar tying, concrete pouring, and curing. The overall process is complex and highly susceptible to environmental influences. Second, it is costly and resource-intensive. The manufacture of concrete pedestals requires not only large quantities of cement, sand, and rebar, but also significant investment in labor and machinery, resulting in high overall costs. Another significant problem is insufficient heat dissipation. When the distribution cabinet is directly supported on a concrete pedestal, the bottom has limited contact area with the air, hindering heat dissipation and easily leading to increased internal temperature, affecting the equipment's operational stability and lifespan. This heat dissipation problem is particularly pronounced in high-temperature environments or under prolonged full-load operation, potentially causing overheating, insulation aging, and other safety hazards.

[0004] In summary, the traditional fixing method of distribution cabinets in current power transmission projects has problems such as high construction difficulty, low installation efficiency, and high cost. It not only affects the construction progress and economy, but may also have a certain impact on the reliability and safety of equipment operation. Utility Model Content

[0005] In view of the problems of high construction difficulty, low installation efficiency, high cost and insufficient heat dissipation performance of outdoor distribution cabinet fixing structures in current power transmission projects, this utility model provides a fixing structure for power transmission project distribution cabinets.

[0006] This utility model is implemented as follows: a fixed structure for a power transmission engineering distribution cabinet, characterized in that it includes a construction base, a beam, and a distribution cabinet. The construction base forms a support body on the ground; the beam forms a bridge-like frame installed between two construction bases; the distribution cabinet is installed on the beam, and a space under the beam is formed between the lower part of the distribution cabinet and the ground.

[0007] In the above technical solution, preferably, the beam body includes four horizontal beams distributed in a matrix, and the two ends of the beam body are respectively fixed to the two building bases; the power distribution cabinet is fixedly installed on the two upper beam bodies.

[0008] In the above technical solution, preferably, the lower part of the power distribution cabinet is provided with a base frame, the base frame is provided with a sleeve hole for the beam to pass through, and the two beams located above pass through the sleeve hole of the base frame.

[0009] In the above technical solution, preferably, the beams are connected by reinforcing beams.

[0010] In the above technical solution, preferably, the reinforcing beam is an X-shaped structure composed of two inclined beams, with the two ends of the inclined beams respectively connected to the two beams located at opposite corners.

[0011] In the above technical solution, preferably, a sliding sleeve is fitted on the beam body, the end of the inclined beam body is connected to the sliding sleeve by fasteners, and the middle parts of the two inclined beam bodies forming an X-shaped structure are connected by fasteners.

[0012] In the above technical solution, preferably, the foundation is provided with a through hole, and the end of the beam is inserted into the through hole.

[0013] In the above technical solution, preferably, the building base is provided with a pre-embedded sleeve, and the insertion hole is formed in the pre-embedded sleeve.

[0014] This invention proposes a novel fixing structure for power transmission engineering distribution cabinets. This structure uses existing structures as foundation supports and detachable, assembleable beams to form a direct carrier, thus constructing a bridge-like fixed support structure. Compared to traditional concrete platforms, this structure exhibits significant advantages and improvements in several aspects.

[0015] First, this fixed structure significantly reduces the size and footprint of concrete structures. Traditional concrete platform installation methods often require extensive foundation construction, while the bridge-type fixed support structure only requires foundation support in necessary locations, greatly reducing the amount of civil engineering work. This not only saves construction land but also reduces construction difficulty, making the layout of distribution cabinets more flexible, especially suitable for situations with limited space or complex terrain.

[0016] Secondly, this structure significantly improves construction efficiency and reduces the amount of work. Because it uses detachable and assembleable beams, large-scale concrete pouring and curing, earthwork excavation, and extensive foundation construction are unnecessary during construction, thus reducing procedures and shortening the construction cycle. Furthermore, the modular design of the beams allows for rapid on-site installation after factory prefabrication, avoiding delays caused by weather or construction conditions in traditional methods and improving the overall project progress.

[0017] The reusability of materials is a major advantage of this structure. Traditional concrete platforms, once constructed, are difficult to dismantle and reuse during later modifications or relocations, leading to resource waste. In contrast, the detachable and modular beams used in this invention not only facilitate installation and dismantling but can also be reused in different locations, thereby reducing construction waste, lowering project costs, and improving resource utilization. This feature is particularly important in power transmission projects where flexible adjustments to the distribution cabinet layout are required, making the overall structure more sustainable and economical.

[0018] Furthermore, this fixed structure effectively improves the heat dissipation performance of the distribution cabinets. Due to the bridge-style support method, a space is created beneath the beams of the row of distribution cabinets, allowing air to circulate freely at the bottom of the cabinets, thus enhancing heat dissipation. Compared to the limited heat dissipation caused by traditional concrete pedestals that are flush with the ground, this design helps reduce the internal temperature of the cabinets, improves the stability of equipment operation, reduces the risk of failure due to overheating, and extends the service life of the equipment. It is particularly suitable for high-temperature environments or scenarios involving long-term full-load operation.

[0019] In summary, the fixed structure of the power distribution cabinet in this power transmission project has successfully overcome the shortcomings of traditional concrete platform structures by optimizing the foundation support method, introducing detachable and assembleable beams, and constructing bridge-type fixed supports. It has achieved optimizations in many aspects, such as reducing land occupation, improving construction efficiency, reducing the amount of work, improving material utilization, and improving heat dissipation performance. It can effectively improve the construction convenience, economy, and equipment operation safety of the power transmission project. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] To address the problems of high construction difficulty, low installation efficiency, high cost, and insufficient heat dissipation performance of outdoor distribution cabinet fixing structures in current power transmission projects, this utility model provides a fixing structure for power transmission project distribution cabinets. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0026] Please see Figure 1 A fixed structure for a power transmission engineering distribution cabinet includes a structural base 1, a beam 2, and a distribution cabinet 3. The structural base is the main supporting structure, and the beam is the direct supporting carrier for the distribution cabinet.

[0027] The beam forms a bridge-like frame installed between two structural bases. Specifically, in this embodiment, the beam comprises four horizontal beams arranged in a matrix, with both ends of the beam fixed to the two structural bases. I-beams are used for the beam to ensure support strength. The matrix arrangement refers to the beam forming the four long horizontal sides of a cube. To ensure the strength and stability of the beam, reinforcing beams connect the beams. These reinforcing beams facilitate stress transfer between the four horizontal beams, forming a stable, rigid bridge-like frame beam. For details in this embodiment, please refer to [link to relevant documentation]. Figure 2 The reinforcing beam is an X-shaped structure composed of two inclined beams 4, with each end of the inclined beam connected to two beams located diagonally opposite each other. Further, a sliding sleeve 5 is fitted onto the beam. The sliding sleeve is rectangular, with a rectangular hole on the inside that fits the beam. Its position on the beam is adjustable, depending on the installation location of the distribution cabinet, and it is positioned between two adjacent distribution cabinets to form an axial spacer, further ensuring the stability of the horizontal spacing between the two adjacent distribution cabinets. The ends of the inclined beams are connected to the sliding sleeves by fasteners, and the middle sections of the two inclined beams forming the X-shape are connected by fasteners. Specifically, an ear plate for connecting the inclined beams is welded to the inside of the sliding sleeve. This ear plate has bolt holes for connecting to the ends of the inclined beams, and an elongated hole is opened in the middle of the inclined beam. The two intersecting inclined beams achieve a stable X-shape structure through bolts and nuts with these elongated holes.

[0028] The foundation forms a support structure on the ground, and is a reinforced concrete structure. The foundation has through-holes into which the ends of the beams are inserted, allowing the beams to be inserted from the outside of the foundations to form a bridge-like structure between two foundations. For further details, please refer to [link to relevant documentation]. Figure 3The foundation is equipped with pre-embedded sleeves 6, and the insertion holes are formed in the pre-embedded sleeves, that is, the pipe holes of the pre-embedded sleeves are the insertion holes. The foundation can be cast on-site at the location of the distribution cabinet, or it can be prefabricated in the factory and transported to the location of the distribution cabinet. After the beam is inserted into the foundation, the gaps in the insertion holes can be filled with concrete.

[0029] The distribution cabinet is installed on the beam, forming a space under the beam between the lower part of the cabinet and the ground. Specifically, in this embodiment, multiple distribution cabinets are horizontally arranged and installed on the two upper beams. Please refer to [link / reference]. Figure 4 The distribution cabinet has a base frame 7 at its lower part, with sleeve holes for the beams to pass through. Two beams located at the top pass through the sleeve holes of the base frame. Further, in this embodiment, the lower base frame of the distribution cabinet is a rectangular beam frame, specifically a square tube beam, where the sleeve holes are the beam holes of the parallel beams of the two base frames. Before installation, the distribution cabinet is supported on the ground using pre-support blocks. During the insertion process between the beams and the foundation, the beams pass through the sleeve holes. After the beams are in place, the pre-support blocks are removed, allowing the distribution cabinet to be mounted on the beams. To further ensure the stability of the distribution cabinet's installation position, threaded holes are made in the square tube beams of the base frame of the distribution cabinet. Locking screws passing through the threaded holes further lock the relative position between the base frame and the beams. The bottom of the distribution cabinet is a cabinet base plate mounted on the base frame. This cabinet base plate has grid ventilation holes, and below these ventilation holes is the space under the beams, significantly improving the heat dissipation performance of the distribution cabinet.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
