Description

Technical Field

[0001] This utility model relates to the field of mobile substation technology, and in particular to a noise reduction enclosure for mobile substation equipment. Background Technology

[0002] Mobile substations, as flexible nodes in power systems, are often used for temporary power supply, emergency repairs, or as a supplement to fixed substations. Their core equipment is usually housed in a dedicated transformer enclosure, which provides the necessary physical protection and operating environment for the equipment.

[0003] With urbanization and increasing environmental protection requirements, mobile substations are being deployed closer to residential or office areas. The transformers, fans, and other equipment inside these substations generate significant electromagnetic and mechanical noise during operation, causing interference to the surrounding environment. Therefore, the substation enclosure must possess excellent sound insulation and noise reduction capabilities.

[0004] To achieve noise reduction, existing enclosures typically employ composite sound insulation structures, such as adding multi-layered sound insulation mechanisms composed of sound insulation panels, sound insulation cotton, and other materials to the enclosure walls. To ensure sound insulation effectiveness and structural stability, these sound insulation mechanisms or panels are usually securely fixed to the enclosure frame using numerous bolts or welding methods to ensure tight connections and prevent noise leakage.

[0005] Therefore, this utility model proposes a noise reduction enclosure for mobile substation equipment to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a noise reduction enclosure for mobile substation equipment, aiming to improve the problems of cumbersome disassembly and maintenance and poor noise reduction and sealing effects of existing mobile substation enclosures.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mobile substation equipment noise reduction enclosure, comprising: a substation enclosure, a first enclosure door and a second enclosure door hinged to the substation enclosure, a disassembly and assembly mechanism fixed to the substation enclosure, and a sound insulation mechanism that can be disassembled and assembled by the disassembly and assembly mechanism;

[0008] The disassembly and assembly mechanism has a threaded shell fixedly connected to the transformer box body, a rotating block threadedly connected to the threaded shell, a connecting shell, the connecting shell accommodating a push post and a locking block, the rotating block abutting against the push post, the push post abutting against the locking block, a rotating post rotatably connected inside the connecting shell, a rotating groove formed on the locking block, a pin provided on the rotating post and slidingly engaged with the rotating groove, a connecting block fixedly connected to the rotating post, and a connecting post rotatably connected to the connecting block. The connecting post of the disassembly and assembly mechanism is combined with the sound insulation mechanism by a detachable connection.

[0009] Preferably, the connecting shell is fixed to the transformer box body.

[0010] Preferably, the push post is slidably disposed within the connecting shell along the axial direction of the push post.

[0011] Preferably, the axis of the rotating column is perpendicular to the sliding direction of the pushing column.

[0012] Preferably, the sound insulation mechanism includes a first outer panel and a second outer panel.

[0013] Preferably, sound-absorbing cotton is filled between the first outer panel and the second outer panel.

[0014] Preferably, a sound insulation board is also provided between the first outer panel and the sound insulation cotton.

[0015] Preferably, the sound insulation mechanism further includes a sealing ring.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of cumbersome disassembly and assembly and low maintenance efficiency caused by the reliance on traditional bolts to fix existing substation box components by setting up a disassembly and assembly mechanism that links components such as rotating blocks, pushing columns, locking blocks and rotating columns. It achieves the effect of quickly locking or loosening components such as sound insulation mechanisms by rotating them, thus improving the convenience of on-site maintenance and deployment.

[0018] 2. This utility model solves the problems of existing enclosure noise reduction structures being simple, having gaps that easily lead to noise leakage, and having poor sound insulation effect by setting up a multi-layer composite sound insulation mechanism consisting of a first outer plate, a second outer plate, a sound insulation board, sound insulation cotton, and a sealing ring. It achieves the effect of effectively reducing equipment operating noise and improving environmental friendliness through the synergistic effect of multiple means of blocking, absorption, and sealing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 The present invention provides an embodiment of a mobile substation equipment noise reduction enclosure, comprising a substation enclosure 1, a first enclosure door 3 and a second enclosure door 4 hinged to the substation enclosure 1, the mobile substation equipment noise reduction enclosure further comprising a disassembly and assembly mechanism 2 fixed to the substation enclosure 1, and a sound insulation mechanism 5 that can be disassembled and assembled by the disassembly and assembly mechanism 2, the disassembly and assembly mechanism 2 being used to quickly lock or release the sound insulation mechanism 5 from the substation enclosure 1, and the sound insulation mechanism 5 being used to block the noise generated by the operation of the equipment inside the substation enclosure 1.

[0028] As one of the core innovations, the disassembly and assembly mechanism 2 includes a threaded shell 201 fixedly connected to the transformer box 1. The threaded shell 201 is threadedly connected to the rotating block 203. The disassembly and assembly mechanism 2 also includes a connecting shell 204, which houses a push column 202 and a locking block 205. The end of the rotating block 203 abuts against one end of the push column 202, and the other end of the push column 202 abuts against the locking block 205. A rotating column 207 is rotatably connected inside the connecting shell 204. A rotating groove 206 is provided on the locking block 205. A pin is provided on the rotating column 207 that slides with the rotating groove 206. A connecting block 208 is fixedly connected to the end of the rotating column 207. A connecting column 209 is rotatably connected to the connecting block 208. The connecting column 209 is detachably connected to the locking part provided on the sound insulation mechanism 5.

[0029] Specifically, the threaded shell 201 is fixed to the inner wall of the transformer box 1 by welding or bolting, providing a stable installation base for other components of the disassembly and assembly mechanism 2. The rotating block 203 is a component that is easy to hold and operate. By rotating the rotating block 203, the rotating block 203 generates axial displacement along the thread of the threaded shell 201, thereby driving the push column 202 to move. The push column 202 is slidably disposed in the connecting shell 204 along its axial direction, linearly transmitting the thrust of the rotating block 203 to the locking block 205. The locking block 205 generates linear reciprocating motion under the push of the push column 202. The rotating groove 2 on the locking block 205... 06 is an inclined guide groove. The rotating column 207 is rotatably installed in the connecting shell 204. The axis of the rotating column 207 is perpendicular to the sliding direction of the pushing column 202. When the locking block 205 moves linearly, the pin provided on the rotating column 207 slides in the rotating groove 206 and is constrained by the groove wall, forcing the rotating column 207 to rotate around its own axis, thereby converting the linear motion of the locking block 205 into the rotational motion of the rotating column 207. The connecting block 208 transmits the torque of the rotating column 207 to the connecting column 209. The connecting column 209 serves as the locking actuator and achieves engagement or disengagement with the sound insulation mechanism 5 by rotation.

[0030] The sound insulation mechanism 5 achieves efficient noise reduction through its multi-layer composite structure, and achieves rapid installation and disassembly through cooperation with the disassembly and assembly mechanism 2. The sound insulation mechanism 5 includes a first outer plate 501 and a second outer plate 505 arranged parallel to the wall of the transformer box 1. The first outer plate 501 and the second outer plate 505 together form the inner and outer support frame of the sound insulation mechanism 5. Sound insulation cotton 504 is filled between the first outer plate 501 and the second outer plate 505. Furthermore, a sound insulation board 502 is also arranged between the first outer plate 501 and the sound insulation cotton 504.

[0031] Specifically, the first outer plate 501 and the second outer plate 505 are metal plates with a certain strength, providing structural stability and external protection for the sound insulation mechanism 5. The sound insulation cotton 504 is a porous sound-absorbing material used to absorb sound wave energy. The sound insulation board 502 is a high-density board used to further block and reflect noise, and can effectively absorb and block noise in different frequency bands.

[0032] To further improve the overall sealing performance, the sound insulation mechanism 5 also includes a sealing ring 503. The sealing ring 503 is set at the joint between the sound insulation mechanism 5 and the transformer box 1. When the sound insulation mechanism 5 is installed on the transformer box 1, the sealing ring 503 is deformed under pressure to fill all potential gaps and prevent noise leakage. In the assembled state, the connecting column 209 of the disassembly mechanism 2 is detachably connected to the snap-fit ​​part opened on the sound insulation mechanism 5. By operating the disassembly mechanism 2, the connecting column 209 can be rotated to lock or release the snap-fit ​​part on the sound insulation mechanism 5, thereby firmly fixing the sound insulation mechanism 5 as an integral module on the transformer box 1, or quickly disassembling it from the transformer box 1, ensuring the stable and reliable installation of the noise reduction module and the convenient and efficient maintenance and disassembly.

[0033] To provide a stable installation reference, the connecting shell 204 is fixed to the inner wall of the transformer box 1. To ensure linear force transmission, the push column 202 is slidably disposed within the connecting shell 204 along the axial direction of the push column 202. To construct the basic framework of the sound insulation structure, the sound insulation mechanism 5 includes a first outer plate 501 and a second outer plate 505 disposed parallel to the wall of the transformer box 1. To absorb sound energy, sound insulation cotton 504 is filled between the first outer plate 501 and the second outer plate 505. To enhance the sound wave blocking, a sound insulation plate 502 is also disposed between the first outer plate 501 and the sound insulation cotton 504. To prevent noise leakage, the sound insulation mechanism 5 also includes a sealing ring 503, which is disposed at the junction of the sound insulation mechanism 5 and the transformer box 1. To achieve effective conversion of the direction of movement, the axis of the rotating column 207 is perpendicular to the sliding direction of the push column 202.

[0034] Working principle: When the sound insulation mechanism 5 needs to be disassembled, the rotating block 203 is operated. Due to the threaded connection between the rotating block 203 and the threaded shell 201, the rotating block 203 generates axial displacement. The end of the rotating block 203 abuts against one end of the pushing column 202, which slides and pushes the locking block 205 to move. The rotating groove 206 on the locking block 205 slides with the pin on the rotating column 207. The linear movement of the locking block 205 forces the rotating column 207 to rotate around its axis. The rotating column 207 drives the fixedly connected connecting block 208 to rotate, and the connecting block 208 drives the rotatably connected connecting column 209 to rotate. Finally, the connecting column 209 disengages from the locking part on the sound insulation mechanism 5, realizing the quick disassembly of the sound insulation mechanism 5. When installing the sound insulation mechanism 5, the rotating block 203 is operated in the opposite direction, and the connecting column 209 rotates and locks the locking part of the sound insulation mechanism 5, realizing quick fixation.

[0035] During equipment operation, the noise inside the transformer box 1 is blocked by the sound insulation mechanism 5. The first outer plate 501 and the second outer plate 505 of the sound insulation mechanism 5 provide structural support and outer layer isolation. The sound insulation cotton 504 and the sound insulation board 502 absorb and dissipate sound waves. The sealing ring 503 is set at the joint between the sound insulation mechanism 5 and the transformer box 1 to prevent noise from leaking from the gaps, thereby achieving efficient noise reduction.
