Description

Technical Field

[0001] This utility model relates to the field of prefabricated substations, and in particular to a maintenance mechanism for prefabricated substations. Background Technology

[0002] The main function of a prefabricated substation is to transform and distribute electrical energy, reducing high-voltage power to a low voltage suitable for users. Therefore, it is an indispensable and important component of the power system.

[0003] Chinese patent application number CN201420743629.0 provides a prefabricated substation. This solution provides good heat dissipation by setting the finned body on the prefabricated substation body. The arrangement of the arc portion, the protrusion and the heat-conducting layer makes the heat transfer more complete, further improving the heat dissipation efficiency. It has the beneficial effect of good heat dissipation and has a simple structure.

[0004] Existing prefabricated substations have certain drawbacks in use. First, the enclosure structure of traditional prefabricated substations is mostly bolted together. When the internal components of the prefabricated substation need maintenance and repair, disassembling the prefabricated substation is very inconvenient, which affects the convenience of operation. To address this, we propose a maintenance mechanism for prefabricated substations. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a maintenance mechanism for a prefabricated substation. By setting up insertion rods and positioning rods, when the prefabricated substation body needs maintenance, multiple positioning rods are pulled. Under the action of the reset ring, the positioning rods move, which in turn drives the positioning block to separate the positioning block from the snap-fit ​​component at the inner end of the bracket. This allows multiple reinforcing frames to be initially released from their fixed constraints on the prefabricated substation body. Then, by separating the insertion rods from the reinforcing frames, multiple reinforcing frames can be easily disassembled. This facilitates the disassembly and assembly of the prefabricated substation body for maintenance, improving the convenience of maintenance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A prefabricated substation maintenance mechanism includes a prefabricated substation body, with a connecting mechanism movably connected to the outer end of the prefabricated substation body and a positioning mechanism slidably connected to the inner end of the connecting mechanism.

[0008] The inner end of the prefabricated substation body is equipped with symmetrically distributed insertion rods. The insertion rods are movably connected to the connecting mechanism. Multiple positioning rods are slidably connected to the rear of the prefabricated substation body. The positioning rods are T-shaped. The outer end of the positioning rod is fitted with a reset ring. The front end of the positioning rod is equipped with a positioning block. The outer end of the positioning block is fitted with a bracket. The inner end of the bracket is slidably connected with symmetrically distributed snap-fit ​​components.

[0009] The installation of insertion rods and positioning rods improves the ease of maintenance of this prefabricated substation.

[0010] Furthermore, the inner end of the positioning block is provided with symmetrically distributed positioning grooves, and the positioning grooves are movably connected to the snap-fit ​​component.

[0011] By installing snap-fit ​​connectors, the main body of the prefabricated substation can be fixed to the connection cover at the rear end.

[0012] Furthermore, each of the card holders has a connector installed on its outer end, and the connector is located at the inner end of the card holder.

[0013] By installing connectors, the ease of connecting and disassembling this structure can be improved.

[0014] Furthermore, a guide ring is fitted onto the outer end of the positioning rod, and an adjustment groove is formed on the outer end of the guide ring, which is located at the inner end of the connecting mechanism.

[0015] By installing the adjustment groove, the moving guide ring and positioning rod can be restricted and guided, making the positioning rod more stable during adjustment and preventing deviation, thus improving the adjustment effect of the positioning rod and positioning block.

[0016] Furthermore, a connecting cover is movably connected to the rear end of the prefabricated substation body, and multiple buffer columns are installed on the top of the prefabricated substation body.

[0017] The installation of buffer pillars increases the stability of the protective roof.

[0018] Furthermore, a protective top is installed at the upper end of the buffer column, and symmetrically distributed slots are opened at the outer end of the box-type substation body, with a reinforcing frame movably connected to the outer end of the slot.

[0019] By installing a protective top, damage to the main body of the prefabricated substation from objects at height can be prevented.

[0020] Furthermore, the reinforcing frame is evenly distributed at the rear end of the box-type substation body, the reinforcing frame has a U-shaped structure, the inner end of the reinforcing frame is equipped with symmetrically distributed elastic elements, and the outer end of the elastic elements is equipped with a locking block.

[0021] The installation of the reinforcement frame and locking block further improves the ease of maintenance of this prefabricated substation.

[0022] Furthermore, the card block one is movably connected to the slot.

[0023] By installing slots, the symmetrically distributed slots can be engaged with the first locking block, allowing for multiple fixing methods between the reinforcement frame and the main body of the prefabricated substation.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. By setting up insertion rods and positioning rods, when the main body of the prefabricated substation needs maintenance, multiple positioning rods are pulled. Under the action of the reset ring, the positioning rods move and drive the positioning block, causing the positioning block to separate from the snap-fit ​​part at the inner end of the bracket. This allows multiple reinforcement frames to be initially released from the fixing restriction of the main body of the prefabricated substation. Then, the insertion rods are separated from the reinforcement frames, allowing multiple reinforcement frames to be easily disassembled. This facilitates the disassembly and assembly of the main body of the prefabricated substation and improves the convenience of maintenance.

[0026] 2. By setting up a snap-fit ​​component, the snap-fit ​​component can snap into the positioning slot, making the connection between the positioning block and the card frame more stable, and fixing the installation between the box-type substation body and the rear connection cover.

[0027] 3. By setting up reinforcement frames and locking blocks, multiple U-shaped reinforcement frames can be engaged with a pair of locking blocks at the inner end of the slot, allowing multiple reinforcement frames to be initially positioned on the outside of the connecting cover and the main body of the box-type substation. Furthermore, this structure is easy to disassemble, giving the device multiple structures that are easy to fix and disassemble, further improving the convenience of maintenance of the box-type substation.

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0036] Reference Figure 1-5 As shown, a box-type substation maintenance mechanism is provided in a preferred embodiment of the present invention, including a box-type substation body 1, a connecting mechanism 2 movably connected to the outer end of the box-type substation body 1, and a positioning mechanism 3 slidably connected to the inner end of the connecting mechanism 2.

[0037] The inner end of the prefabricated substation body 1 is equipped with symmetrically distributed insertion rods 301. The insertion rods 301 are movably connected to the connecting mechanism 2. Multiple positioning rods 302 are slidably connected to the rear of the prefabricated substation body 1. The positioning rods 302 have a T-shaped structure. The outer end of the positioning rods 302 is fitted with a reset ring 303. The front end of the positioning rods 302 is equipped with a positioning block 304. The outer end of the positioning block 304 is fitted with a bracket 305. The inner end of the bracket 305 is slidably connected with symmetrically distributed snap-fit ​​pieces 306.

[0038] Reference Figure 2-5 As shown, the inner end of the positioning block 304 is provided with symmetrically distributed positioning grooves 307, and the positioning grooves 307 are movably connected to the snap-fit ​​member 306.

[0039] Reference Figure 4-5 As shown, further, each of the outer ends of the snap-fit ​​306 is equipped with a connector 308, which is located at the inner end of the card holder 305.

[0040] Reference Figure 2 and Figure 4 As shown, further, a guide ring 309 is sleeved on the outer end of the positioning rod 302, and an adjustment groove 310 is opened on the outer end of the guide ring 309. The adjustment groove 310 is located at the inner end of the connecting mechanism 2.

[0041] By installing the positioning rod 302, which moves under the force of the reset ring 303, the positioning rod 302 moves and drives the positioning block 304, causing the positioning block 304 to separate from the snap-fit ​​part 306 at the inner end of the card holder 305. This allows the multiple reinforcing frames 205 to be initially released from the fixed restriction of the box-type substation body 1. The snap-fit ​​part 306 can also snap into the positioning groove 307. The connecting part 308 is an adjustable structure, which can form a connection structure at the outer end of the snap-fit ​​part 306, allowing the snap-fit ​​part 306 to easily snap into the positioning block 304. When the positioning block 304 is adjusted, the snap-fit ​​part 306 can also be easily separated, making the connection between the positioning block 304 and the card holder 305 more stable. Then, by separating the insertion rod 301 from the reinforcing frame 205, the multiple reinforcing frames 205 can be easily disassembled, which facilitates the disassembly and maintenance of the box-type substation body 1.

[0042] Reference Figure 1 As shown, the rear end of the prefabricated substation body 1 is movably connected with a connecting cover 201, and the top of the prefabricated substation body 1 is equipped with multiple buffer columns 202.

[0043] Reference Figure 1-2 As shown, a protective top 203 is installed on the upper end of the buffer column 202, and slots 204 are symmetrically distributed on the outer end of the box-type substation body 1. A reinforcing frame 205 is movably connected to the outer end of the slot 204.

[0044] Reference Figure 1-2 As shown, further, the reinforcing frame 205 is evenly distributed at the rear end of the box-type substation body 1. The reinforcing frame 205 has a U-shaped structure. The inner end of the reinforcing frame 205 is equipped with symmetrically distributed elastic elements 206, and the outer end of the elastic elements 206 is equipped with a locking block 207.

[0045] Reference Figure 2 As shown, further, the card block 207 and the slot 204 are movably connected.

[0046] By installing buffer columns 202, a support connection structure can be formed at the outer end of the protective top 203. The protective top 203 can form a protective structure at the outer end of the box-type substation body 1, preventing objects at height from damaging the box-type substation body 1. Multiple U-shaped reinforcing frames 205, together with a pair of locking blocks 207, can be locked into the inner end of the slot 204, so that multiple reinforcing frames 205 can be initially positioned on the outside of the connecting cover 201 and the box-type substation body 1. Moreover, this structure is easy to disassemble, giving the device multiple structures that are easy to fix and disassemble. The symmetrically distributed slots 204 can be locked with the locking blocks 207, giving the reinforcing frames 205 and the box-type substation body 1 multiple fixing methods.

[0047] Specific implementation process: When the prefabricated substation body 1 is in use, multiple U-shaped reinforcing frames 205, together with a pair of locking blocks 207, can be locked into the inner end of the slot 204, so that multiple reinforcing frames 205 are initially positioned on the outside of the connecting cover 201 and the prefabricated substation body 1. The symmetrically distributed slots 204 can be locked into the locking blocks 207. At this time, the positioning rod 302 works with the positioning block 304 for secondary positioning. The locking piece 306 can be locked into the positioning groove 307 set in the positioning block 304, so that the connection between the positioning block 304 and the locking frame 305 is more stable, and the reinforcing frame 205 and the prefabricated substation body 1 have multiple fixing methods.

[0048] When the connecting cover 201 needs to be disassembled for convenient maintenance of internal components of the prefabricated substation body 1, multiple positioning rods 302 are pulled. Under the force of the reset ring 303, the positioning rods 302 move and drive the positioning block 304, causing the positioning block 304 to separate from the snap-fit ​​306 at the inner end of the clip 305. This allows the multiple reinforcing frames 205 to be initially released from the fixed restriction of the prefabricated substation body 1. Then, the insertion rod 301 is separated from the reinforcing frame 205, allowing the multiple reinforcing frames 205 to be easily disassembled, thus facilitating the disassembly and maintenance of the prefabricated substation body 1.
