Description
Technical Field
[0001] This utility model relates to the field of prefabricated substation technology, and in particular to a prefabricated substation frame structure. Background Technology
[0002] Prefabricated substations are an alternative to conventional civil engineering power distribution rooms. They integrate high-voltage switchgear, distribution transformers, and low-voltage power distribution devices into a single structure, combining transformer voltage reduction and low-voltage power distribution functions. This results in better safety and easier installation and positioning. They are suitable for locations such as mines, factories, oil and gas fields, and wind power stations. Existing prefabricated substations consist of an internal frame and an outer shell, with the internal frame serving only to support the equipment.
[0003] For example, patent CN221226819U discloses a box-type substation frame structure, which relates to the field of substation frame structure technology. Specifically, the box-type substation frame structure includes a lower frame, an upper frame, and a protective end cover. The lower frame consists of two bottom rods, two horizontal rods, a bottom plate, and four vertical rods. The upper frame consists of a fixed frame and two support rods. The two ends of the bottom rods and horizontal rods are fixedly welded to each other. The four vertical rods are fixedly welded to the connection between the bottom rods and horizontal rods. The two horizontal rods have mounting holes. The vertical rods are fixedly connected to a main inclined beam and a side inclined beam. The support rods are fixedly installed at the bottom of the fixed frame. The bottom of the support rods is fixedly connected to a mounting block. The top of the protective end cover is fixedly installed with a fixed block. The top of the fixed block is fixedly connected to a support column. The top of the support column is fixedly installed with a collar.
[0004] The aforementioned prefabricated substation frame structure has a fixed frame size that cannot be adjusted during use. It can only be installed on prefabricated substations of fixed sizes. For prefabricated substations of different sizes, multiple frame structures of different sizes must be prepared, which increases the investment cost. Therefore, this application provides a prefabricated substation frame structure to meet the requirements. Utility Model Content
[0005] The technical problem this utility model aims to solve is to provide a prefabricated substation frame structure that addresses the issue that existing prefabricated substations have fixed frame dimensions that cannot be adjusted, and can only be installed on prefabricated substations of fixed sizes. For prefabricated substations of different sizes, multiple frame structures of different sizes must be prepared, thereby increasing the investment cost.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A prefabricated substation frame structure includes upper and lower frame bodies. Each of the upper and lower frame bodies has an adjustment mechanism installed inside and outside. The adjustment mechanism includes an adjustment component and multiple guide frames. Height adaptation mechanisms are installed at the bottom ends of both sides of the two frame bodies and at the two corners of the ends of the multiple guide frames. Installation mechanisms are installed on both sides of the top of the upper frame body. The adjustment component is installed inside the lower two frame bodies. The adjustment component includes a transmission rod and a lead screw sleeve. The upper and lower sides of the lead screw sleeve are jointly fixed with guide frames. A locking component is installed on one side of the middle of the upper and lower frame bodies.
[0008] Optionally, the adjusting assembly includes a rotating rod, which is installed in the middle of the frame. A first bevel gear is fixedly provided on one side of the rotating rod, and a second bevel gear meshes with one side of the first bevel gear. A transmission rod is fixedly provided in the middle of the second bevel gear. Third bevel gears are fixedly provided on both ends of the rotating rod, and a fourth bevel gear meshes with the sides of the two third bevel gears. A positive and negative lead screw is fixedly provided in the middle of the two fourth bevel gears, and lead screw sleeves are screwed on both sides of the middle of the two positive and negative lead screws. Guide grooves are provided on the inner walls of both sides of the frame.
[0009] Optionally, the guide groove and the guide frame are connected by a movable guide connection.
[0010] Optionally, the locking assembly includes a gear, which is fixed to one end of the transmission rod. A fixing block is fixed to one side of the middle portion of the frame, and a return spring is installed on the outer side of the fixing block. A pull block is fixed to the end of the return spring, and a guide rod is fixed to the inner middle of the pull block. A guide groove is opened in the middle of the fixing block, and a locking block is fixed to the end of the guide rod.
[0011] Optionally, the guide rod and the guide groove in the middle of the fixed block are connected by a movable guide connection.
[0012] Optionally, the size of the card block matches the size of the tooth grooves distributed around the gear.
[0013] Optionally, the height adaptation mechanism includes an inner guide frame, which is fixed at the bottom four corners of the upper frame. The inner guide frame has a first screw groove on its side. An outer guide frame is fixed at the top four corners of the lower frame. An alignment screw groove is opened on one side of the outer guide frame, and a first bolt rod is screwed in the middle of the alignment screw groove.
[0014] Optionally, the alignment groove and the distributed first threaded groove are of the same size.
[0015] Optionally, the installation mechanism includes installation blocks, which are symmetrically installed on the top two sides of the upper frame. A connecting column is fixed to the top of the multiple installation blocks, and a lifting ring is fixed to the top of the connecting column. A second screw groove is opened on both sides of the installation block, and a second bolt rod is screwed into the middle of the second screw groove.
[0016] Optionally, the second threaded groove and the second bolt rod are symmetrically distributed along the vertical central axis of the mounting block.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above scheme, by setting an adjustment mechanism, when it is necessary to adjust the size of the box-type substation frame, personnel can manually rotate the transmission rod on one side of the middle of the two frame bodies in advance to make the second bevel gear at the end rotate, which in turn rotates the first bevel gear and the rotating rod that meshes with it. In this state, the third bevel gear at both ends of the rotating rod will rotate the fourth bevel gear and the central positive and negative screw synchronously. The screw sleeve that interacts with the screw can guide the fixed guide frame to move away from or towards each other with the guide groove, thereby adjusting the size of the box-type substation frame. It is worth mentioning that before the personnel turn the transmission rod, one hand needs to pull the pull block so that the end guide rod, under the action of the guide groove, can disengage the locking block from the corresponding tooth groove of the gear fixed at one end of the transmission rod. After the subsequent adjustment is completed, the personnel slowly release the pull block, and under the reset spring, the locking block can be locked into the alignment tooth groove, thereby improving the adjustment stability between the frame body and the guide frame.
[0019] By setting up a height adaptation mechanism, when it is necessary to change the distance between the upper and lower frame bodies, the personnel can adjust the depth distance between the inner guide frame below the corresponding guide frame and the outer guide frame above the corresponding guide frame. After the adjustment is completed, the personnel can insert the first bolt rod thread into the alignment screw groove and the corresponding first screw groove to achieve the fixed locking of the inner guide frame and the outer guide frame.
[0020] By setting up an installation mechanism, the component lifting rings of the installation mechanism installed on the upper frame can facilitate personnel to carry out hoisting operations on the whole structure during use. This not only facilitates operation but also reduces the disassembly and assembly of frames and the potential damage during transportation. Attached Figure Description

[0035] like Figures 1 to 5As shown, an embodiment of this utility model provides a box-type substation frame structure, including upper and lower frame bodies 1. Adjustment mechanisms 2 are installed inside and outside each of the upper and lower frame bodies 1. Each adjustment mechanism 2 includes an adjustment component 21 and multiple guide frames 22. Height adaptation mechanisms 3 are installed at the bottom ends of both sides of the two frame bodies 1 and at the two corners of the ends of the multiple guide frames 22. Installation mechanisms 4 are installed on both sides of the top of the upper frame body 1. The adjustment component 21 is installed inside the lower two frame bodies 1. The adjustment component 21 includes a rotating rod 211, which is installed in the middle of the frame body 1. A first bevel gear 212 is fixed to one side of the rotating rod 211, and a second bevel gear 213 meshes with one side of the first bevel gear 212. A transmission rod 214 is fixed in the middle of the frame 13. Third bevel gears 215 are fixed around both ends of the rotating rod 211, and fourth bevel gears 216 mesh with the sides of the two third bevel gears 215. Positive and negative lead screws 217 are fixed in the middle of the two fourth bevel gears 216, and lead screw sleeves 218 are screwed onto both sides of the middle of the two positive and negative lead screws 217. Guide grooves 219 are opened on the inner walls of both sides of the frame 1. The guide grooves 219 and the guide frame 22 are connected in a movable guide manner. The upper and lower sides of the lead screw sleeves 218 are jointly fixed with the guide frame 22. A locking assembly 23 is installed on one side of the middle of the upper and lower frame bodies 1. The locking assembly 23 includes a gear 231, which is fixed around one end of the transmission rod 214. A fixing block 232 is fixedly provided on one side of the component, and a return spring 233 is installed on the outer side of the fixing block 232. A pull block 234 is fixedly provided at the end of the return spring 233, and a guide rod 235 is fixedly provided in the middle of the inner side of the pull block 234. A guide groove 236 is opened in the middle of the fixing block 232. The guide rod 235 and the guide groove 236 in the middle of the fixing block 232 are connected by a movable guide. A locking block 237 is fixedly provided at the end of the guide rod 235. The size of the locking block 237 matches the size of the tooth grooves distributed around the gear 231. When it is necessary to adjust the size of the box-type substation frame, the personnel can manually rotate the transmission rod 214 on one side of the middle of the two frame bodies 1 in advance to rotate the second bevel gear 213 at the end, which in turn rotates the first bevel gear 212 and the rotating rod 211 that mesh with it. In this state, the third bevel gear 215 located around both ends of the rotating rod 211 will drive the fourth bevel gear 216 and its central positive and negative lead screw 217 to rotate synchronously. The lead screw sleeve 218, which interacts with the lead screw, can guide its fixed guide frame 22 in conjunction with the guide groove 219 to move relatively away or closer, thereby adjusting the size of the box-type substation frame. It is worth mentioning that before the operator turns the transmission rod 214, one hand needs to pull the pull block 234 so that its end guide rod 235, under the action of the guide groove 236, can disengage the locking block 237 from the corresponding tooth groove of the gear 231 fixed at one end of the transmission rod 214. After the adjustment is completed, the operator slowly releases the pull block 234, and under the reset of the return spring 233, the locking block 237 can be engaged into the corresponding tooth groove.This improves the stability of the adjustment between frame 1 and guide frame 22.
[0036] The height adaptation mechanism 3 includes an inner guide frame 31, which is fixed at the bottom four corners of the upper frame 1. The inner guide frame 31 has a first screw groove 32 on its side. The lower frame 1 has an outer guide frame 33 fixed at the top four corners. The outer guide frame 33 has an alignment screw groove 34 on one side. A first bolt rod 35 is screwed into the middle of the alignment screw groove 34. The alignment screw groove 34 and the distributed first screw groove 32 have the same size. When it is necessary to change the distance between the upper and lower frame 1, the personnel can adjust the depth distance between the inner guide frame 31 below the upper frame 1 and the outer guide frame 33 above the corresponding guide frame 22. After adjustment, the personnel can insert the first bolt rod 35 into the alignment screw groove 34 and the corresponding first screw groove 32 to lock the inner guide frame 31 and the outer guide frame 33.
[0037] Furthermore, the installation mechanism 4 includes installation blocks 41, which are symmetrically installed on both sides of the top of the upper frame 1. Connecting columns 42 are fixedly provided on the top of the multiple installation blocks 41, and lifting rings 43 are fixedly provided on the top of the connecting columns 42. Second screw grooves 44 are provided on both sides of the installation blocks 41, and second bolt rods 45 are screwed in the middle of the second screw grooves 44. The second screw grooves 44 and the second bolt rods 45 are symmetrically distributed along the vertical central axis of the installation blocks 41. The lifting rings 43 of the installation mechanism 4 installed on the upper frame 1 can facilitate personnel to lift the whole structure during use, which is convenient for operation and can also reduce the disassembly and assembly of the frames and the possible damage during transportation.
[0038] The working principle of the technical solution provided by this utility model is as follows:
[0039] When adjusting the dimensions of the prefabricated substation frame, personnel can manually rotate the second bevel gear 213 at the end of the transmission rod 214 on one side of the middle of the two frame bodies 1, causing it to rotate. This rotates the first bevel gear 212 and the rotating rod 211 that mesh with it. In this state, the third bevel gear 215 located around both ends of the rotating rod 211 will rotate synchronously with the fourth bevel gear 216 and the central positive and negative lead screw 217. The lead screw sleeve 218, which interacts with the lead screw, can guide the respective fixed guide frame 22 to move relatively away or closer with the guide groove 219, thereby adjusting the dimensions of the prefabricated substation frame. It is worth mentioning that before personnel turn the transmission rod 214, one hand needs to pull the pull block 234 so that the end guide rod 235, under the action of the guide groove 236, disengages the locking block 237 from the corresponding tooth of the gear 231 fixed at one end of the transmission rod 214. After the adjustment is completed, the personnel slowly release the pull block 234. Under the reset of the return spring 233, the above-mentioned locking block 237 can be locked into the alignment tooth groove, thereby improving the adjustment stability between the frame body 1 and the guide frame 22. Secondly, when it is necessary to change the distance between the upper and lower frame bodies 1, the personnel can adjust the depth distance between the inner guide frame 31 below the upper frame body 1 and the outer guide frame 33 above the corresponding guide frame 22. After the adjustment is completed, the personnel can insert the first bolt rod 35 into the alignment screw groove 34 and the corresponding first screw groove 32 to achieve the fixed locking of the inner guide frame 31 and the outer guide frame 33. Finally, the component lifting ring 43 of the installation mechanism 4 installed on the upper frame body 1 can facilitate the personnel to carry out the overall hoisting operation during use. It is convenient to operate and can also reduce the disassembly and assembly between frames and the possible damage during transportation.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0041] The above description is only a preferred embodiment of the present utility model.
