Description

Technical Field

[0001] This utility model relates to the field of low-voltage power distribution systems, and specifically provides a base for low-voltage power modules. Background Technology

[0002] Low-voltage power distribution systems mainly consist of distribution transformers, incoming line cabinets, outgoing line cabinets, and capacitor compensation cabinets, used for the distribution, control, and protection of electrical energy. Currently, more and more projects pursue high-density on-site installation and efficient construction, requiring manufacturers to assemble the individual low-voltage power distribution system units into a single power module at the factory. This module can then be easily installed and fixed on-site for direct use. However, these integrated low-voltage power modules cannot be disassembled during transportation, making transport extremely difficult. Using hoisting lugs for transfer easily leads to the modules falling apart or detaching. Ensuring reliable transportation of the entire low-voltage power module system remains a significant challenge. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a base for low-voltage power modules, ensuring the reliability of the low-voltage power modules during hoisting and relocation. The specific technical solution is as follows:

[0004] A base for a low-voltage power module includes a long frame and a wide frame. The long frame and the wide frame are arranged in pairs and enclose a rectangular frame. Multiple hanging shaft structures are evenly arranged on both sides of the rectangular frame along its length. The bottom surface of the rectangular frame is connected to the ground, and power equipment is sequentially connected to the upper surface of the rectangular frame along its length.

[0005] In this solution, by setting up an overall rectangular frame, all the power equipment of the entire power module is pre-installed on the rectangular frame and hoisted using the lifting shaft structure on the rectangular frame. This allows for the rapid and efficient transfer of the entire power module, and the rectangular frame also bears the load to prevent damage to the power equipment during transportation.

[0006] Preferably, the distance between the two long frames is the same as the depth of the deepest electrical equipment cabinet, ensuring that when the electrical equipment is installed on the rectangular frame, the long frames bear the main force.

[0007] Since the long frame is the main load-bearing structure, in order to improve the load-bearing capacity of the long frame, multiple wide frames are set between the two long frames, and lightweight auxiliary frames are set between adjacent wide frames. The lightweight auxiliary frames are parallel to the wide frames, and the adjacent wide frames and lightweight auxiliary frames divide the rectangular frame into multiple UPS equipment installation areas and multiple cabinet installation areas.

[0008] By connecting two long frames with multiple wide frames, the load-bearing capacity and stability of the long frames can be effectively improved. The lightweight auxiliary frame is lighter in weight, ensuring the sturdiness of the rectangular frame while avoiding excessive weight of the rectangular frame and increasing the load during hoisting.

[0009] Preferably, the cabinet mounting area is enclosed by a wide frame and a lightweight auxiliary frame, and the mounting holes of the cabinet mounting area are set on the long frame. The weight of an electrical cabinet is shared by at least one wide frame to ensure the load-bearing capacity of the cabinet mounting area.

[0010] Preferably, a single UPS equipment installation area is enclosed by a wide frame and a lightweight auxiliary frame; or, a single UPS equipment installation area is enclosed by two lightweight auxiliary frames, and a reinforcing frame connects the UPS equipment installation area to an adjacent UPS equipment installation area or cabinet installation area, the reinforcing frame being disposed between the two long frames to improve overall strength.

[0011] Preferably, the installation of two consecutive UPS devices includes at least one wide rack.

[0012] To ensure the entire rectangular frame can be lifted, the lifting shaft structure includes a lifting pile and a sleeve. The sleeve is fixedly mounted on the long frame, and the lifting pile is slidably disposed within the sleeve. Limiting plates are provided at both ends of the lifting pile. In this design, the lifting pile can protrude from the long frame through sliding for lifting, and after lifting, it can also be completely retracted into the long frame through sliding. This avoids the lifting pile protruding after the power module is installed, which could easily trip people, and is also more aesthetically pleasing.

[0013] To prevent the slings from scratching the cabinet of the electrical equipment during hoisting, the hoisting shaft structure also includes an auxiliary baffle set on the long frame. The auxiliary baffle is set above the sleeve and extends toward and toward both sides of the rectangular frame.

[0014] Preferably, the long frame, wide frame, lightweight auxiliary frame, and reinforcing frame are made of channel steel.

[0015] Preferably, the lifting shaft structure further includes a lifting reinforcing channel steel, which is correspondingly provided with the sleeve. The lifting reinforcing channel steel is fixedly fastened to the concave surface of the channel steel of the long frame, so that the sleeve passes through both the long frame and the lifting reinforcing channel steel, ensuring the reliability of the lifting shaft structure based on the use of channel steel.

[0016] The channel steel of the long frame and the wide frame are provided with a baffle with an observation window on one side of the channel opening. The baffle covers the concave surface of the channel steel of the long frame and the wide frame, which is more aesthetically pleasing and can also protect the wiring on the concave surface of the channel steel. The observation window allows maintenance personnel to observe the grounding continuity of the long frame and the wide frame.

[0017] The long channel steel is provided with wiring openings at its ends. The wiring in the concave surface of the channel steel can be connected to the internal grounding point, ensuring convenient grounding in actual projects.

[0018] The beneficial effects of this utility model are as follows: By setting up an overall rectangular frame, the power equipment of the entire power module can be pre-installed on the rectangular frame and hoisted by the lifting shaft structure on the rectangular frame. This allows for the rapid and efficient transfer of the entire power module, and the rectangular frame can also bear the force to prevent damage to the power equipment during transportation.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of this utility model.

[0026] Example 1:

[0027] A base for a low-voltage power module, such as Figure 1 and Figure 2 As shown, it includes a long frame 1 and a wide frame 2. The long frame 1 and the wide frame 2 are arranged in pairs and enclose a rectangular frame. Multiple hanging shaft structures 3 are evenly arranged on both sides of the rectangular frame along its length. The bottom surface of the rectangular frame is connected to the ground, and the upper surface of the rectangular frame is connected to electrical equipment in sequence along its length.

[0028] Specifically, the long frame 1 and the wide frame 2 can be made of channel steel, with mounting holes on both the top and bottom. The upper surface is bolted to the electrical equipment, and the distance between the two long frames 1 is the same as the depth of the deepest electrical equipment cabinet, ensuring that the long frame 1 bears the main load when the electrical equipment is installed on the rectangular frame. The lower surface is grounded via bolts. By setting up an integral rectangular frame, all the electrical equipment of the entire power module can be pre-installed on this rectangular frame and hoisted using the lifting shaft structure 3 on the rectangular frame. This allows for quick and efficient transportation of the entire power module, and the rectangular frame bearing the load also prevents damage to the electrical equipment during transportation.

[0029] Furthermore, since the electrical equipment is all installed on the long frame 1, which is the main load-bearing structure, multiple wide frames 2 are arranged between the two long frames 1 to improve its load-bearing capacity. Lightweight auxiliary frames 4 are arranged between adjacent wide frames 2, parallel to the wide frames 2. The adjacent wide frames 2 and lightweight auxiliary frames 4 divide the rectangular frame into multiple UPS equipment installation areas 5 and multiple cabinet installation areas 6. The lightweight auxiliary frames 4 are smaller in mass and size than the wide frames 2. The spacing between the wide frames 2 and the model and spacing of the lightweight auxiliary frames 4 are determined through simulation calculations based on the weight of the actual installed electrical equipment. By using multiple wide frames 2 to connect the two long frames 1, the load-bearing capacity and stability of the long frame 1 can be effectively improved. The lighter weight of the lightweight auxiliary frames 4 ensures the sturdiness of the rectangular frame while preventing the overall weight of the rectangular frame from becoming excessive and increasing the load during hoisting. For example... Figure 1 and Figure 2 In the embodiment shown, when the wide frame 2 uses 16# channel steel, the lightweight auxiliary frame 4 uses 10# channel steel, which is of a smaller grade, in order to reduce the cost and weight of the entire base as much as possible while ensuring that the strength is qualified.

[0030] Example 2:

[0031] Based on Example 1, since the depth dimensions of all low-voltage cabinets in the entire power module are consistent, while the UPS equipment is provided by a third party and its depth dimension may be less than the length of the width frame 2, in order to ensure that the entire base structure has sufficient strength to install electrical equipment, such as Figure 2 As shown, the cabinet installation area 6 is enclosed by a wide frame 2 and a lightweight auxiliary frame 4. The mounting holes 7 of the cabinet installation area 6 are set on the long frame 1. Two adjacent cabinet installation areas 6 share a wide frame 2 or a lightweight auxiliary frame 4. The weight of an electrical cabinet is shared by at least one wide frame 2 to ensure the load-bearing capacity of the cabinet installation area.

[0032] Each UPS installation area 5 is enclosed by a wide frame 2 and a lightweight auxiliary frame 4; or, each UPS installation area 5 is enclosed by two lightweight auxiliary frames 4. A reinforcing frame 8 connects each UPS installation area 5 to an adjacent UPS installation area 5 or cabinet installation area 6. The reinforcing frame 8 is positioned between two long frames 1 to improve overall strength. The reinforcing frame 8 uses the same structure as the lightweight auxiliary frame 4. Since the UPS installation areas 5 are generally continuous, the UPS installation areas 5 at both ends are adjacent to the cabinet installation area 6 and are directly connected to the reinforcing frame 8 by welding. It should be noted that in this embodiment, two consecutive UPS installation areas contain at least one wide frame 2. The actual configuration will be determined based on simulation results.

[0033] Example 3:

[0034] Based on the above embodiments, in order to ensure that the entire rectangular frame can be lifted, such as Figure 1 and Figure 3 As shown, the lifting shaft structure 3 includes a lifting pile 301 and a sleeve 302. The sleeve 302 is fixedly installed on the long frame 1, and the lifting pile 301 is slidably installed in the sleeve 302. Limiting plates 303 are provided at both ends of the lifting pile 301. In this embodiment, the base has eight lifting points, so there are eight lifting shaft structures 3. In each lifting shaft structure 3, the lifting pile 301 can protrude from the long frame 1 by sliding for lifting. At the same time, after the lifting is completed, the lifting pile 301 can also be completely retracted into the long frame 1 by sliding. This avoids the lifting pile 301 protruding after the power module is installed, which could easily trip people, and is also more aesthetically pleasing.

[0035] To prevent the slings from scratching the electrical equipment cabinet during hoisting, the lifting shaft structure 3 also includes an auxiliary baffle 304 mounted on the long frame 1. The auxiliary baffle 304 is positioned above the sleeve 302 and extends towards both sides of the rectangular frame. The auxiliary baffle 304 is as follows: Figure 3 As shown, after extending horizontally, a downward-bending side plate structure is provided to hold the sling in place.

[0036] It should be noted that when the long frame 1 is a channel steel, the lifting shaft structure 3 also includes a lifting reinforcing channel steel 305. The lifting reinforcing channel steel is correspondingly provided with the sleeve 302. The lifting reinforcing channel steel 305 is fixedly fastened to the concave surface of the channel steel of the long frame 1, so that the sleeve 302 passes through both the long frame 1 and the lifting reinforcing channel steel 305 at the same time, ensuring the sturdiness of the lifting shaft structure 3 based on the use of channel steel.

[0037] The channel steel of the long frame 1 and the wide frame 2 has a baffle 9 with an observation window 10 on one side of the channel opening. The observation window 10 can be directly sealed with a transparent polycarbonate sheet. The baffle 9 covers the concave surface of the channel steel of the long frame 1 and the wide frame 2, which is more aesthetically pleasing and also protects the wiring on the concave surface of the channel steel. The observation window 10 allows maintenance personnel to observe the grounding continuity of the long frame 1 and the wide frame 2. The end of the channel steel of the long frame 1 is provided with a wiring opening 11. The wiring in the middle of the concave surface of the channel steel can be connected to the internal grounding point, ensuring convenient grounding in actual projects.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
