Description

Technical Field

[0001] The invention belongs to the technical field of substations, and in particular relates to a modular box-type substation. Background Art

[0002] Modular substation is a new type of substation that modularizes the substation equipment and functions according to certain rules and standards. Most of the modules are produced and assembled in a factory environment. The factory has standardized production processes, strict quality control systems and good production conditions to ensure stable and reliable production quality of the modules and reduce quality problems in on-site construction. For example, the module shell can be precisely processed and anti-corrosion treated in the factory to improve the protection level and service life of the equipment.

[0003] For example, the invention patent application with patent application number 202211040809.8 discloses a modular box-type substation shell and its assembly method, whose specific components are all sheet-like structures, thus achieving the effect of easy transportation, and no assembly of small parts is required. The assembly process is simple, the assembly time is short, and the technical proficiency of the assembly workers is not high, which solves the problems existing in the prior art.

[0004] For example, the invention patent with patent application number 201711217253.4 discloses a modular prefabricated cabin body, a modular prefabricated cabin and a substation; the modular prefabricated cabin body reduces the production and processing area, reduces the processing difficulty, improves production efficiency, reduces processing costs, and solves transportation problems through a flexible assembly mode. It solves the problems of high manufacturing cost and difficult processing and transportation of prefabricated cabins in the prior art.

[0005] The above two modular substation settings overcome the on-site assembly of small parts and use a "piece" structure to be assembled by bolts; however, during the on-site assembly process, a crane is required to lift and dock each "piece". During the docking process, the crane operation and the external environment have a great impact, and shaking may occur, making it difficult to complete the docking assembly.

[0010] The push plate is fixedly connected with a wedge-shaped push block; the fixed base frame is provided with a mounting bolt hole, and the mounting bolt hole is located above the wedge-shaped push block.

[0011] The scraper assembly comprises a guide rod and a scraper, wherein the guide rod is fixedly connected to the top cover; the scraper is slidably connected to the guide rod; and a connecting ear fixedly connected to the traction rope is provided on the scraper.

[0012] The top module also includes a centering mechanism, which includes a driving frame and a centering card plate. The driving frame is located below the top cover and is slidably connected to the top cover. The centering card plate passes through the top cover and is fixedly connected to the driving frame.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figure 1-11 As shown, a modular box-type substation includes a base frame module 1, a side panel module 2 and a top module 3.

[0024] The chassis module 1 includes a fixed chassis 10 and support columns 11. There are four support columns 11. Two support columns 11 are hinged on both sides of the fixed chassis 10. A connecting plate 12 is fixed to the lower end of each support column 11. The connecting plate 12 is fixedly connected to the fixed chassis 10 by bolts. During transportation, each support column 11 is rotated and laid flat to reduce its height. After being transported to the designated installation site, each support column 11 is reversely rotated to a vertical state and then fixed.

[0025] There are four side panel modules 2, which are specifically divided into a front side panel module, a rear side panel module, a left side panel module and a right side panel module; specifically: the front side panel module is provided with an openable and closable door body, and the rear side panel module is provided with corresponding ventilation holes.

[0026] The four side panel modules 2 have the same basic structure, and all include an external panel 20, a fixed frame 21, and a pair of connection and positioning columns 22. The fixed frame 21 and the pair of connection and positioning columns 22 are fixedly connected to the external panel 20. The connection and positioning columns 22 are provided with connection holes 23 that pass through from top to bottom. The lifting rope 26 can pass through the connection hole 23 and extend from the bottom of the connection and positioning column 22 to be clamped with the fixed base frame 10. The fixed base frame 10 is provided with a corresponding clamping groove 24, and the bottom of the lifting rope 26 is fixed with a corresponding connection pin 25. Specifically: there are two lifting ropes 26, and the two lifting ropes 26 pass through the corresponding connection holes 23 respectively; the upper ends of the two lifting ropes 26 are fixedly connected with a hanging plate, and the hanging plate is fixed with a lifting ear connected to the crane.

[0027] The side panel module 2 is docked with the base frame module 1 by lifting. The specific operation is as follows: pass the two lifting ropes 26 through the corresponding connection holes 23 respectively, and insert the connection pins 25 at the lower ends of each lifting rope 26 into the corresponding slots 24 respectively. Then, the hanging plate is lifted by the crane. During the lifting process, the two lifting ropes 26 are in a taut state, forming a structure similar to a "guide rail", so that the side panel module 2 can be moved along the lifting ropes 26 to the position where it needs to be docked, and it is lifted to a vertical state. Finally, the fixed frame 21 is fixedly connected to the fixed base frame 10 and the support column 11 by bolts.

[0028] After the connection is fixed, the connecting pin 25 is removed from the slot 24 and is pulled out from the installed side panel module 2; thereafter, the remaining side panel modules 2 are installed according to the above operation process.

[0029] The top module 3 includes a top cover 30 and a scraper assembly 31; for the convenience of lifting, a lifting lug can be provided on the top cover 30, and the hoist cooperates with the lifting lug to lift the top module 3 as a whole; of course, other lifting methods can also be used for connection. The bottom of the top cover 30 is fixedly connected with a plug-in column 32 plugged into the connection hole 23, so as to realize the plug-in of the top cover 30 and each side panel module 2. After plugging, the top cover 30 and the side panel module 2 are also fixedly connected by bolts. The scraper assembly 31 is arranged on the top cover 30, and winches 33 are respectively fixed on the two side panel modules 2 arranged opposite to each other; the scraper assembly 31 is connected with a traction rope 34.

[0030] The installation process of the top module 3 is as follows: first, the top module 3 is lifted by a crane; then the two ends of the traction rope 34 are respectively passed through the top cover 30, the plug-in column 32 and the connection positioning column 22 to be detachably fixedly connected with the corresponding winch 33. After that, the traction rope 34 is tightened by the winch 33, so that the traction rope 34 is in a taut state, that is, a structural setting similar to a "guide rail" is formed; at the same time, when the crane lowers the top module 3, the winch 33 also continues to tighten the traction rope 34; until the plug-in column 32 on the top cover 30 is plugged into the connection hole 23, the installation of the top module 3 is completed.

[0031] Furthermore, the card slot 24 is specifically composed of an insertion portion 240 and a clamping portion 241; the connecting pin 25 is inserted through the insertion portion 240 and then moved to the clamping portion 241, and the connecting pin 25 is clamped by the clamping portion 241; a push assembly 27 is provided at the card slot 24. After the installation between the side panel module 2 and the chassis module 1 is completed, the connecting pin 25 is moved from the clamping portion 241 to the insertion portion 240 by the push assembly 27, and then the connecting pin 25 can be removed from the card slot 24 by lifting the hanging plate upwards.

[0032] Furthermore, the push assembly 27 includes a push plate 270, a pull rod 271 and a compression spring 272; the push plate 270 is arranged inside the fixed base frame 10, the pull rod 271 passes through the fixed base frame 10 and is fixedly connected to the push plate 270, and the pull rod 271 and the push plate 270 are fixedly connected by a thread. The compression spring 272 is sleeved outside the pull rod 271, and the two ends of the compression spring 272 are respectively in contact with the push plate 270 and the inside of the fixed base frame 10. After the installation between the side plate module 2 and the base frame module 1 is completed, the pull rod 271 is pulled outward to move the push plate 270 outward and move the connecting pin 25 from the clamping portion 241 to the insertion portion 240.

[0033] Furthermore, the push plate 270 is fixedly connected with a wedge-shaped push block 273; the fixed base frame 10 is provided with a mounting bolt hole 13, and the mounting bolt hole 13 is located above the wedge-shaped push block 273. That is, when the side panel module 2 is connected to the mounting bolt hole 13 by bolts, the corresponding bolts extend into the fixed base frame 10 and cooperate with the wedge-shaped push block 273; as the bolts continue to extend, they drive the wedge-shaped push block 273 to move forward continuously until the bolts are tightened, and the push plate 270 is moved outward through the wedge-shaped push block 273, and the connecting pin 25 is moved from the clamping portion 241 to the insertion portion 240. Through the above-mentioned structural setting, the operation of pulling the pull rod 271 outward can be omitted; and it can be ensured that the connecting pin 25 will move to the insertion portion 240 only after the bolts are tightened.

[0034] Furthermore, the scraper assembly 31 includes a guide rod 310 and a scraper 311. The guide rod 310 is fixedly connected to the top cover 30; the scraper 311 is slidably connected to the guide rod 310; and a connection ear 312 fixedly connected to the traction rope 34 is provided on the scraper 311. The left end of the traction rope 34 is tightened by the left winch 33, while the right end of the traction rope 34 is loosened by the right winch 33; thereby, the scraper 311 moves leftward along the guide rod 310; conversely, the left end of the traction rope 34 is loosened by the left winch 33, while the right end of the traction rope 34 is tightened by the right winch 33; thereby, the scraper 311 moves rightward along the guide rod 310. That is, the left-right movement of the scraper 311 is realized by the cooperation between the two winches 33, thereby cleaning the debris, snow, etc. on the upper surface of the top cover 30. At the same time, through the above-mentioned traction method, the traction rope 34 applies downward pressure to the scraper 311 so that it can fit the upper surface of the top cover 30.

[0035] Specifically: a guide pulley 36 connected to the traction rope 34 is provided on the top cover 30, a limit baffle 37 is provided at the guide pulley 36, and the limit baffle 37 is fixedly connected to the top cover 30; the limit baffle 37 blocks the traction rope 34 to prevent the traction rope 34 from separating from the guide pulley 36.

[0036] Furthermore, in order to prevent the scraper assembly 31 from moving due to the traction rope 34 when installing the top module 3, a centering mechanism 35 is also provided. The centering mechanism 35 includes a driving frame 350 and a centering clamp 351. The driving frame 350 is located below the top cover 30 and is slidably connected to the top cover 30. The centering clamp 351 passes through the top cover 30 and is fixedly connected to the driving frame 350. A limiting groove 352 cooperating with the scraper 311 is provided on the centering clamp 351.

[0037] A spring plate 353 is provided between the driving frame 350 and the top cover 30 , and two ends of the spring plate 353 are hinged to the top cover 30 and the driving frame 350 respectively.

[0038] Due to the action of the spring plate 353, there is a gap between the driving frame 350 and the lower surface of the top cover 30; the limiting groove 352 on the centering clamp 351 is engaged with the scraper 311, which can limit the random movement of the scraper 311. When the top cover 30 is plugged into the side panel module 2, the driving frame 350 is pressed down by the top cover 30, and it moves up relative to the top cover 30, and drives the centering clamp 351 to move up accordingly, so that the limiting groove 352 is not engaged with the scraper 311, that is, after the top cover 30 is installed in place, the movement of the scraper 311 is not restricted by the centering mechanism 35.

[0039] Specifically, the driving frame 350 is slidably connected to the plug-in posts 32 on the top cover 30 .

[0040] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
