Description

[0001] Technology Area*

[0002] The present invention relates to the technical field of transformer substations, and in particular to an anti-dumping box-type transformer substation and a method thereof. Background Art

[0003] Prefabricated box-type substations have many advantages such as light component weight, fast construction, easy production, transportation and hoisting, and low overall cost, and are widely used in various projects.

[0004] Chinese patent CN110445048A discloses a prefabricated compact intelligent box-type substation, including a prefabricated steel plate shell, a data acquisition and monitoring control system, and a temperature-sensing self-starting fire extinguishing device. The prefabricated steel plate shell is provided with a high-voltage cabinet, a transformer, and a low-voltage distribution board in sequence according to the line routing direction. The prefabricated steel plate shell adopts a prefabricated structure and a double-layer box top, including an upper box top and a lower box top. The upper box top adopts a push-pull structure. The box-type substation is compact and easy to operate and maintain. However, the box-type substation still has the following problems:

[0005] 1. During the construction and installation of box-type substations, construction workers usually pre-build the box-type transformer foundation at the installation location. After the construction is completed, the prefabricated box-type transformer is transported to the construction site, the prefabricated box-type transformer is hoisted on the box-type transformer foundation, and then the wiring and fixing of the prefabricated box-type transformer are completed to complete the installation of the box-type transformer. However, the existing box-type transformer only relies on the box-type transformer foundation to support the box-type transformer base. In the face of severe weather, the supporting performance may be insufficient, and there is a safety hazard of the box-type transformer tipping over;

[0006] 2. A transformer is installed in the box-type substation. The transformer is large in size and is easily damaged when subjected to external impact. Therefore, it is inconvenient to disassemble and repair the transformer, and it is difficult to quickly fix the transformer.

[0007] Based on this, the present invention designs an anti-dumping box-type substation and a method thereof to solve the above problems. Summary of the invention

[0008] In view of the above-mentioned shortcomings of the prior art, the present invention provides an anti-dumping box-type substation and a method thereof.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] An anti-dumping box-type substation comprises a box-type substation body;

[0011] A plurality of hanging points for hanging the box-type transformer body are fixedly installed symmetrically front and back at the bottom of the box-type transformer body, and heat dissipation holes for cooperating with the heat dissipation fan are opened on the left and right side walls of the hanging points;

[0012] The lower end of the box-type transformer body is provided with a plurality of anti-dumping mechanisms to make the box-type transformer body installed on the prefabricated box-type transformer foundation more stable;

[0013] The upper end of the box-type transformer body is provided with an opening and closing top cover mechanism for quickly opening the top cover and part of the side wall of the box-type transformer body, so that the transformer can be lifted out of the box-type transformer body;

[0014] The inner bottom of the box-type transformer body is provided with a quick fixing mechanism for quick disassembly and assembly of the transformer;

[0015] The side wall of the box-type transformer body is provided with an auxiliary fire prevention mechanism for timely closing the heat dissipation holes when a fire occurs in the box-type transformer body;

[0016] The anti-dumping mechanism includes two groups of foldable internal support components arranged at the bottom of the box transformer body for supporting the inner wall of the prefabricated box transformer foundation and a locking component arranged between the foldable internal support components. The locking component allows the foldable internal support components to always remain in the state of being unfolded to support the inner wall of the prefabricated box transformer foundation, so that the box transformer body obtains additional supporting performance through the foldable internal support components, thereby increasing the anti-dumping ability of the box transformer body.

[0017] Furthermore, the opening and closing top cover mechanism includes side panels, a top cover, an opening and closing assembly and an auxiliary support assembly. The side panels and the top cover are respectively located at the rear side and the top of the box-type transformer body. The lower end of the side panel is hinged to the bottom of the box-type transformer body, the upper end of the side panel is hinged to one end of the top cover, and the other end of the top cover moves back and forth at the top of the hanging point through the opening and closing assembly symmetrically arranged at the top inside the box-type transformer body; a fixing assembly for fixing the top cover to the box-type transformer body is provided at the front end of the top cover; auxiliary support assemblies for supporting the side panels in the open and closed state are symmetrically arranged on the left and right inner walls of the box-type transformer body.

[0018] Furthermore, the foldable inner support assembly includes a support block, a sliding sleeve and a sliding rod. The two support blocks are located at the front and rear sides of the bottom of the box transformer body and are distributed on the left and right sides of the sliding rod. The upper end of the support block is hinged to the bottom of the box transformer body through a hinge seat, and the outer side of the support block is set to be a plane for supporting the inner wall of the prefabricated box transformer foundation; the end of the support block close to the sliding rod is rotatably installed with a sliding sleeve through a bearing, and the sliding rod is slidably connected to the inner side of the sliding sleeve.

[0019] Furthermore, the locking assembly includes a block, a slot and a cross bar. Each support block is provided with a block fixedly connected to the bottom of the box-type transformer body on one side close to the sliding rod, which is used to limit the rotation of the support block in one direction; the inner sides of the sliding rods of the two locking assemblies are provided with a slot connected to the cross bar, and the cross bar is inserted between the two sliding rods to limit the rotation of the support block in the other direction; the block, the slot and the cross bar cooperate to ensure that the support block always remains vertical.

[0020] Furthermore, the opening and closing assembly includes a slide rail, a pulley and a connecting arm, the slide rail is fixedly installed on the inner top of the box-type transformer body; one end of the connecting arm is fixedly connected to the top cover, and the other end of the connecting arm is rotatably installed with a pulley rollingly connected to the slide rail through a bearing; by pulling the top cover, the front end of the top cover can slide back and forth in the horizontal direction, so that an opening structure is formed on the top of the box-type transformer body.

[0021] Furthermore, the auxiliary support assembly includes a telescopic support structure composed of an outer sliding sleeve and an inner sliding rod. The outer sliding sleeve is hinged to the inner wall of the box transformer body through a hinge seat, one end of the inner sliding rod is limitedly slidably connected to the outer sliding sleeve, and the other end of the inner sliding rod is hinged to the side panel through the hinge seat. Therefore, after the side panel and the top cover are opened and closed, the telescopic support structure can assist in pulling the side panel to prevent the top cover from being damaged due to the pulling of the side panel.

[0022] Furthermore, the quick fixing mechanism includes a plurality of groups of positioning components and clamping components arranged on both sides of the inner bottom, and the positioning components and the clamping components cooperate to fix the bottom channel steel of the transformer and the transformer body in multiple dimensions.

[0023] Furthermore, the auxiliary fire protection mechanism includes a limit block, a baffle, a through groove, a sensor and a driving structure for controlling the vertical movement of the baffle. The two limit blocks are fixedly connected to the inner wall of the box-type transformer body, and a baffle for blocking the heat dissipation holes is installed between the limit blocks for limited sliding. The baffle is provided with a plurality of through grooves corresponding to the heat dissipation holes one by one. The inner wall of the box-type transformer body is also fixedly installed with a sensor for monitoring whether a fire occurs in the box-type transformer body.

[0024] Furthermore, in a natural state, the through slots of the baffle are aligned with the heat dissipation holes of the transformer body; in a natural state, the through slots of the baffle are aligned with the heat dissipation holes; when the sensor detects a fire in the transformer body, the driving structure drives the baffle to move vertically so that the through slots are misaligned with the heat dissipation holes.

[0025] In order to better achieve the purpose of the present invention, the present invention also provides a construction method of an anti-dumping box-type substation, comprising the following steps:

[0026] Step 1: After connecting the lifting rope to the lifting point, use a crane or other lifting equipment to lift the main body of the box-type transformer and move it to the prefabricated box-type transformer foundation;

[0027] Step 2: Twist the slide bar to gradually rotate the support block toward the slide bar until the stopper blocks the support block, so that the support block remains vertical;

[0028] Step 3: Insert the cross bar into the slot between the two slide bars. The stopper, the slot and the cross bar cooperate to keep the support block vertical at all times, so that the outer side of the stopper can support the inner wall of the prefabricated box-type transformer foundation, providing additional support capacity for the box-type transformer body;

[0029] Step 4: Release the fixing effect of the fixing assembly on the top cover, pull the top cover backward, and make the top cover slide on the top of the box-type transformer body through the pulley and the slide rail until the pulley moves to its travel limit. At this time, the side plate is driven by the top cover and also flipped backward and pulled by the auxiliary support assembly, and the top of the box-type transformer body forms an open structure;

[0030] Step 5: Insert the transformer through the opening structure of the transformer box body and complete the installation and fixation through the quick fixing mechanism.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0033] When the transformer needs to be moved, the top and part of the side walls of the transformer box body can be quickly opened through the opening and closing top cover mechanism, so that the transformer can be directly lifted out from the transformer box body, and the operating field of view and operating space are increased, which is convenient for wiring the transformer. At the same time, the quick fixing mechanism set at the bottom of the transformer box body can realize the quick fixing of the transformer, effectively improving the construction efficiency.

DETAILED DESCRIPTION

[0046] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0047] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0048] Embodiment 1

[0049] In some embodiments, please refer to the attached instructions. Figure 1-10 , an anti-dumping box-type substation, including a box-type substation body 1.

[0050] A plurality of hanging points 11 for hanging the box-type transformer body 1 are fixedly installed symmetrically front and back on the bottom of the box-type transformer body 1 , and heat dissipation holes 12 for cooperating with heat dissipation fans are opened on the left and right side walls of the hanging points 11 .

[0051] The lower end of the box-type transformer body 1 is provided with a plurality of groups of anti-dumping mechanisms 2 for making the box-type transformer body 1 installed on the prefabricated box-type transformer foundation 6 more stable.

[0052] The upper end of the transformer body 1 is provided with an opening and closing top cover mechanism 3 for quickly opening the top cover and part of the side wall of the transformer body 1, which is used to directly lift the transformer out of the transformer body 1 when repairing the transformer, and has a larger operating field of view and operating space.

[0053] The inner bottom of the box-type transformer body 1 is provided with a quick fixing mechanism 5 for quickly fixing the transformer.

[0054] The side wall of the transformer body 1 is provided with an auxiliary fire protection mechanism 4 for timely closing the heat dissipation holes 12 when a fire occurs in the transformer body 1, so that a nearly closed environment is formed in the transformer body 1, and inert gas is injected into the transformer body 1 to extinguish the fire in cooperation with fire-fighting facilities.

[0055] The anti-dumping mechanism 2 includes two sets of foldable internal support components 21 arranged at the bottom of the box-type transformer body 1 for supporting the inner wall of the prefabricated box-type transformer foundation 6, and a locking component 22 arranged between the foldable internal support components 21. The foldable internal support components 21 are always kept in an unfolded state through the locking component 22, so that the box-type transformer body 1 obtains additional supporting performance through the foldable internal support components 21, thereby increasing the anti-dumping ability of the box-type transformer body 1.

[0056] In the present invention, after the lifting rope is connected to the lifting point 11, the box-type transformer main body 1 is lifted and moved to the prefabricated box-type transformer foundation 6 by a lifting equipment such as a crane, and the foldable internal support component 21 at the bottom of the box-type transformer main body 1 is unfolded, and the foldable internal support component 21 is kept in an unfolded state by the locking component 22 to support the inner wall of the prefabricated box-type transformer foundation 6, so that the box-type transformer main body 1 obtains additional supporting performance equivalent to that of reinforcing ribs, increases the anti-dumping ability of the box-type transformer main body 1 in the face of severe weather, and makes full use of the internal space of the prefabricated box-type transformer foundation 6 without affecting the occupied space of the shell of the box-type transformer main body 1.

[0057] When the transformer needs to be moved, the top and part of the side walls of the transformer body 1 can be quickly opened through the opening and closing top cover mechanism 3, so that the transformer can be directly lifted out from the transformer body 1, and the operating field of view and operating space are increased, which is convenient for wiring the transformer; at the same time, the quick fixing mechanism 5 set at the bottom of the transformer body 1 can realize the quick fixing of the transformer, effectively improving the construction efficiency.

[0058] In some embodiments, Figure 2 , 3As shown in 6, the foldable inner support assembly 21 includes a support block 211, a sliding sleeve 212 and a sliding rod 213. The two support blocks 211 are located at the front and rear sides of the bottom of the box-type transformer main body 1 and are distributed on the left and right sides of the sliding rod 213. The upper end of the support block 211 is hinged to the bottom of the box-type transformer main body 1 through a hinge seat, and the outer side of the support block 211 is set to be a plane for supporting the inner wall of the prefabricated box-type transformer foundation 6; the end of the support block 211 close to the sliding rod 213 is rotatably installed with the sliding sleeve 212 through a bearing, and the sliding rod 213 is slidably connected to the inner side of the sliding sleeve 212.

[0059] By folding the support block 211 so that the side of the support block 211 fits against the bottom of the box-type transformer body 1, the box-type transformer body 1 can be normally placed on a supporting structure such as sleepers, thereby facilitating the transportation of the box-type transformer body 1; by twisting the slide bar 213, the support block 211 can be gradually rotated in the direction of the slide bar 213 until the slide bar 213 is vertical. At this time, the outer side of the slide bar 213 is in close contact with the inner wall of the prefabricated box-type transformer foundation 6, which acts as a reinforcing rib, thereby providing additional support capacity for the box-type transformer body 1.

[0060] The locking assembly 22 includes a stopper 221, a slot 222 and a cross bar 223. Each support block 211 is provided with a stopper 221 fixedly connected to the bottom of the box-type transformer body 1 on one side close to the slide bar 213, which is used to limit the rotation of the support block 211 in one direction. The inner sides of the slide bars 213 of the two locking assemblies 22 are provided with a slot 222 engaged with the cross bar 223, and the cross bar 223 is inserted between the two slide bars 213 to limit the rotation of the support block 211 in the other direction. The cooperation of the stopper 221, the slot 222 and the cross bar 223 keeps the support block 211 vertical at all times, so that the stopper 221 can support the inner wall of the prefabricated box-type transformer foundation 6 to maintain the anti-dumping capability.

[0061] like Figure 7-9 As shown, the opening and closing top cover mechanism 3 includes a side plate 31, a top cover 32, an opening and closing assembly 33 and an auxiliary support assembly 34. The side plate 31 and the top cover 32 are respectively located at the rear side and the top of the box-type transformer body 1. The lower end of the side plate 31 is hinged to the bottom of the box-type transformer body 1, and the upper end of the side plate 31 is hinged to one end of the top cover 32. The other end of the top cover 32 moves forward and backward on the top of the hanging point 11 through the opening and closing assembly 33 symmetrically arranged on the top of the box-type transformer body 1. The front end of the top cover 32 is provided with a fixing assembly 35 for fixing the top cover 32 to the box-type transformer body 1, so that the side plate 31 and the top cover 32 are closed to form a closed shell of the box-type transformer body 1. The left and right inner walls of the box-type transformer body 1 are symmetrically provided with auxiliary support assemblies 34 for supporting the side plates 31 in the open and closed state.

[0062] The opening and closing assembly 33 includes a slide rail 331, a pulley 332 and a connecting arm 333. The slide rail 331 is fixedly installed on the inner top of the box-type transformer body 1; one end of the connecting arm 333 is fixedly connected to the top cover 32, and the other end of the connecting arm 333 is rotatably installed with a pulley 332 rollingly connected to the slide rail 331 through a bearing; by pulling the top cover 32, the front end of the top cover 32 can slide back and forth in the horizontal direction, so that an open structure is formed on the top of the box-type transformer body 1, and the side panel 31 is also driven by the top cover 32 to flip backward, further increasing the operating space and operating field of the box-type transformer body 1, not only leaving enough top space for lifting the transformer, but also providing operating space for wiring the transformer and other operations.

[0063] The auxiliary support assembly 34 includes a telescopic support structure consisting of an outer sliding sleeve 341 and an inner sliding rod 342. The outer sliding sleeve 341 is hinged to the inner wall of the box-type transformer body 1 through a hinge seat, one end of the inner sliding rod 342 is connected to the outer sliding sleeve 341 in a limited sliding manner, and the other end of the inner sliding rod 342 is hinged to the side panel 31 through a hinge seat. Therefore, after the side panel 31 and the top cover 32 are opened and closed, the telescopic support structure can be used to assist in pulling the side panel 31 to prevent the top cover 32 from being damaged by the pulling of the side panel 31.

[0064] like Fig.10 As shown, the fixing assembly 35 includes an upper connecting block 351, a lower connecting block 352 and a latch 353. The upper connecting block 351 is fixedly connected to the top cover 32, and the lower connecting block 352 is fixedly installed on the top of the box-type transformer body 1. Matching sockets are provided on the upper connecting block 351 and the lower connecting block 352. When the side panel 31 and the top cover 32 are closed, the sockets of the upper connecting block 351 and the lower connecting block 352 are aligned, and the latch 353 is inserted into the socket and fixed by a nut, thereby fixing the side panel 31, so that the side panel 31 and the top cover 32 remain in a closed state to form a closed outer shell structure of the box-type transformer body 1.

[0065] The quick fixing mechanism 5 includes a plurality of positioning components 51 and a pressing component 52 arranged on both sides of the inner bottom.

[0066] The positioning assembly 51 includes a positioning screw 511 and a positioning baffle 512. The two positioning screws 511 are fixedly connected to the inner bottom of the box-type transformer body 1. The spacing between the two positioning screws 511 is the same as the width of the channel steel at the bottom of the transformer. The positioning baffle 512 is fixedly installed on the upper ends of the two positioning screws 511 by nuts. The positioning baffle 512 is set to be L-shaped, which is used to press the channel steel and support the side wall of the transformer to achieve the positioning of the transformer.

[0067] The clamping assembly 52 includes a clamping screw 521 and a clamping baffle 522. The two clamping baffles 522 are fixedly connected to the inner bottom of the box-type transformer body 1. The spacing between the two clamping screws 521 is the same as the width of the channel steel. The clamping baffle 522 is provided with a sliding groove that is slidably connected to the clamping screw 521.

[0068] In the present invention, after the transformer is hoisted into the transformer box body 1, the channel steel used for supporting the bottom of the transformer is aligned between the positioning screws 511 and the clamping screw 521 and inserted, and the side of the positioning screw 511 is fitted with the positioning baffle 512 to achieve the positioning of the transformer, and then the clamping baffle 522 is installed into the upper end of the clamping screw 521, and the clamping baffle 522 is adjusted forward and backward so that the clamping baffle 522 is fitted with the other side of the transformer, and then the clamping baffle 522 is fixed on the clamping screw 521, so that the channel steel is limited by the positioning screw 511 and the positioning baffle 512, and the bottoms of the positioning baffle 512 and the clamping baffle 522 are pressed against the channel steel, and the positioning baffle 512 and the clamping baffle 522 cooperate to clamp the transformer body, thereby achieving a multi-dimensional fixing effect on the transformer.

[0069] like Figure 4 and 9 As shown, the auxiliary fire prevention mechanism 4 includes a limit block 41, a baffle 42, a through slot 43, a bracket 44, a cylinder 45 and a sensor 46. The two limit blocks 41 are fixedly connected to the inner wall of the box transformer body 1, and a baffle 42 for shielding the heat dissipation holes 12 is installed between the limit blocks 41 in a limited sliding manner and is fitted to the inner wall of the box transformer body 1. The baffle 42 is provided with a plurality of through slots 43 corresponding to the heat dissipation holes 12. The bracket 44 is fixedly connected to the inner wall of the box transformer body 1, and a cylinder 45 is fixedly installed on the bracket 44, and the output end of the cylinder 45 is fixedly connected to the bottom of the baffle 42. The inner wall of the box transformer body 1 is also fixedly installed with a sensor 46 for monitoring whether a fire occurs in the box transformer body 1. The sensor 46 can be a smoke sensor or a temperature sensor. In the natural state, the through groove 43 of the baffle 42 is aligned with the heat dissipation hole 12, so that the transformer body 1 can be ventilated and heat exchanged normally. When the sensor 46 detects a fire in the transformer body 1, the cylinder 45 drives the baffle 42 to move vertically under the limiting action of the limit block 41, so that the through groove 43 is misaligned with the heat dissipation hole 12, thereby forming a nearly sealed environment in the transformer body 1, and cooperating with the fire-fighting equipment to inject inert fire-extinguishing gas into the transformer body 1 to increase its fire-fighting efficiency.
