Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, and in particular to a box-type transformer substation for new energy. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It is a necessary facility for new energy power generation equipment to output electric energy.

[0003] A Chinese patent document with authorization announcement number CN116169571B discloses a landscape-type underground box-type substation, which can circulate and dry the moist moisture inside the storage chamber for storing underground transformers. The drying method is to absorb the moist moisture located below the storage chamber, transport it upward, and finally discharge it downward along the underground pre-buried shell after drying. According to the principle that molecules with larger mass in the gas will precipitate downward and molecules with lighter mass will move upward, the drying efficiency can be effectively accelerated. At the same time, the moist moisture can be dried to the greatest extent, thereby improving the overall effect after drying.

[0004] However, the structural design of the above-mentioned related technology is as follows: when installing the box-type substation underground, a sling is generally put on the box body or on a hanging rod installed on the box body. After the box-type substation enters the underground, the staff is required to go to multiple hanging points to remove the slings set on the box body. However, the pit space used to install the box-type substation is limited, resulting in limited space for the staff to move, which will affect the removal efficiency of the sling, and further affect the installation efficiency of the box-type substation.

[0005] Therefore, a box-type substation for new energy is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides a box-type substation for new energy, aiming to solve the problem in the related art that the slings need to be manually removed when the box-type substation is installed underground, thereby affecting the installation efficiency.

[0007] The box-type substation for new energy of the present invention comprises a box-type substation, wherein a plurality of fixing mechanisms for placing slings are installed on both sides of the bottom of the box-type substation, and a pushing mechanism is provided on the fixing mechanism to push the slings out of the fixing mechanism;

[0008] The fixing mechanism comprises a hanging assembly installed on the box-type substation, a pressure-bearing assembly slidably arranged at the lower part of the hanging assembly, and a movable part slidably arranged at the upper part of the hanging assembly. The pressure-bearing assembly can lift the movable part to limit the pushing mechanism. The hanging assembly has a slot and a through slot for the movable part to move upward.

[0009] The push mechanism includes a sliding assembly, which includes a sliding cylinder elastically slidably connected to the hanging assembly in a transverse direction, and a limiting piece for inserting into a slot is provided on the sliding cylinder;

[0010] The sling can enable the pressure component to lift the movable part and push the limiting part out of the slot, so that the slide can drive the limiting part to cross the slot and be blocked by the movable part. When the pressure component is reset, it can drive the movable part to reset, so that the slide can push the sling out of the hanging component.

[0011] The slide is pushed toward the box-type substation and stops when the limit piece enters the slot. Then the sling is put on the hanging assembly and the pressure assembly is set on the inner side of the sling. The upward movement of the sling can drive the pressure assembly to lift the movable part and push the limit piece out of the slot. At the same time, the movable part extends out of the hanging assembly. At this time, the slide drives the limit piece across the slot and is blocked by the movable part. When the box-type substation lands, the pressure assembly loses the squeezing of the sling and begins to reset and drives the movable part to reset. At this time, the slide loses the obstruction of the movable part and begins to reset and pushes the sling out of the hanging assembly, so as to automatically push the sling out. There is no need for staff to go to each lifting point to remove the sling, thereby improving the removal efficiency of the sling and further improving the installation effect of the box-type substation.

[0012] Preferably, the hanging assembly includes a fixed column installed on the box-type substation, and slide grooves are provided on both sides of the fixed column. A receiving groove connected to the slide groove is provided inside the fixed column, and the pressure-bearing assembly is located in the receiving groove. A receiving groove for accommodating movable parts is provided on the upper part of the fixed column. The slot is arranged on the top side of the fixed column, and the through groove is arranged on the fixed column and close to the side of the slot.

[0013] Preferably, the pressure-bearing assembly includes a pressure-bearing block arranged inside the receiving groove, a mounting plate mounted on the pressure-bearing block, and two wedge blocks mounted on the mounting plate, and the movable part is located above the mounting plate.

[0014] Preferably, the movable part has a horizontal part and a vertical part, the vertical part of the movable part passes through the accommodating groove and extends to the inside of the storage groove, the horizontal part of the movable part is slidably connected in the accommodating groove, and the horizontal part of the movable part is installed with a top block arranged in the slot and a protrusion arranged in the through groove.

[0015] By moving the movable part upward, the limiting part can be pushed out of the slot to release the limiting effect of the limiting part on the slide cylinder.

[0016] Preferably, the pushing mechanism further comprises a slip ring elastically slidably connected in the slide cylinder in a transverse direction, two clamping assemblies are slidably provided on the slip ring, and a push rod for blocking the movement of the slip ring is installed on the box-type substation.

[0017] The push rod can block the movement of the slip ring during the movement of the slide cylinder, thereby extending the clamping assembly out of the slide cylinder.

[0018] Preferably, the clamping assembly includes a clamping plate elastically slidably connected to the slip ring in the transverse direction, a slide plate installed on the clamping plate, and a wedge block 2 installed on the slide plate. The slip ring is provided with a sliding groove 3 for accommodating the clamping plate. The wedge block 1 is located below the wedge block 2, and the slide plate and the wedge block 2 are both slidably connected in the sliding groove 1.

[0019] By cooperating with the wedge block 1 and the wedge block 2, the two clamping plates can be driven to approach each other so as to clamp the sling on the fixing column.

[0020] Preferably, the clamping plate is in an arc shape, teeth are provided on the inner side of the clamping plate, two spring sheets are installed on the slip ring, and the ends of the spring sheets have bending parts.

[0021] By providing a spring sheet, the sling can be limited after being put on the fixed column to prevent the sling from moving on the fixed column. The teeth on the clamping plate can increase the friction between the sling and the clamping plate, thereby improving the clamping effect of the sling and preventing the sling from sliding on the fixed column after the box-type substation is lifted.

[0022] Preferably, one end of the slide cylinder is provided with two slide grooves 2 for the sliding of the splint, the slide grooves 2 and 3 are the same size and correspond to each other, and the slide cylinder and the slip ring are both provided with grooves for the pressure block to pass through.

[0023] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the box-type substation is landed, the pressure-bearing component loses the squeezing of the sling and starts to reset and drives the movable parts to reset, the slide loses the obstruction of the movable parts and starts to reset and pushes the sling out of the hanging assembly, so as to automatically push the sling out, and there is no need for staff to remove the sling from each hanging point, thereby improving the disassembly efficiency of the sling and further improving the installation effect of the box-type substation.

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 7As shown, the box-type substation for new energy of the present invention comprises a box-type substation 10, a fixing mechanism 20 and a pushing mechanism 30. There are multiple fixing mechanisms 20 and pushing mechanisms 30. In this embodiment, there are four fixing mechanisms 20. In other embodiments, there are six, eight or more even numbers of fixing mechanisms 20. Multiple fixing mechanisms 20 are respectively installed on both sides of the bottom of the box-type substation 10. The sling can be put on the fixing mechanism 20, and multiple pushing mechanisms 30 are arranged on the outside of the fixing mechanism 20. After the box-type substation 10 is placed on the ground, the sling on the fixing mechanism 20 can be automatically removed by sliding the pushing mechanism 30, without the need for staff to operate, thereby improving the installation efficiency of the box-type substation 10.

[0037] like Figures 1 to 4 As shown, the box-type substation 10 includes a base 11, a box body 13 and a top plate 14. The box body 13 is installed on the top of the base 11, and the top plate 14 is installed on the top of the box body 13. The fixing mechanism 20 is installed on one side of the base 11, and two top rods 12 are installed on the outside of the base 11 close to the fixing mechanism 20.

[0038] like Figure 2 and Figures 4 to 5 As shown, the fixing mechanism 20 includes a hanging assembly 21, a pressure assembly 22 and a movable member 24. The pressure assembly 22 is slidably disposed at the lower part of the hanging assembly 21, and the movable member 24 is slidably disposed at the upper part of the hanging assembly 21.

[0039] like Figures 4 to 5 As shown, the hanging assembly 21 includes a fixed column 211 installed on the base 11, and a slide groove 23 is provided on both sides of the fixed column 211. A receiving groove 212 connected to the slide groove 23 is provided inside the fixed column 211. The receiving groove 212 is in a T-shape, and the pressure-bearing assembly 22 is located in the receiving groove 212. A receiving groove 213 for accommodating the movable member 24 is provided on the upper part of the fixed column 211, a slot 214 connected to the receiving groove 213 is provided on one side of the top of the fixed column 211, and a through groove 215 connected to the receiving groove 213 is provided on one side of the top of the fixed column 211 near the slot 214.

[0040] like Figures 4 to 6As shown, the pressure assembly 22 includes a pressure block 221, a mounting plate 222 and two wedge blocks 223. The pressure block 221 is slidably connected to the inside of the receiving groove 212. In the initial state, the bottom of the pressure block 221 passes through the receiving groove 212 and extends to the outside of the fixed column 211. The mounting plate 222 is located inside the receiving groove 212 and is installed on the top of the pressure block 221. The two wedge blocks 223 are respectively installed on both sides of the top of the mounting plate 222. When the sling is put on the outside of the fixed column 211, the pressure block 221 can enter the receiving groove 212 by pressing the sling through the upward movement of the external sling.

[0041] like Figure 5 As shown, the movable member 24 has a horizontal portion and a vertical portion. The vertical portion of the movable member 24 is arranged at the end of the horizontal portion of the movable member 24. The vertical portion of the movable member 24 penetrates the receiving groove 213 and extends to the inside of the receiving groove 212. The horizontal portion of the movable member 24 is slidably connected in the receiving groove 213. A top block arranged in the slot 214 is installed on one side of the top of the horizontal portion of the movable member 24. A convex block arranged in the through groove 215 is installed on the side of the top of the horizontal portion of the movable member 24 close to the top block. The height of the convex block is greater than the height of the top block. The top of the convex block is arc-shaped. In the initial state, the top of the convex block fits the outer side of the fixed column 211. When the movable member 24 moves upward, the convex block will first extend out of the fixed column 211.

[0042] like Figure 2 and Figures 4 to 6 As shown, the push mechanism 30 includes a sliding assembly 31 and a slip ring 34. The sliding assembly 31 is slidably arranged on the outside of the fixed column 211, the slip ring 34 is slidably arranged inside the sliding assembly 31 and sleeved on the outside of the fixed column 211, and two clamping assemblies 33 are slidably arranged on the slip ring 34.

[0043] like Figures 4 to 6 As shown, the sliding assembly 31 includes a slide cylinder 311 slidably connected to the outside of the fixed column 211, and a spring 1 32 fixed to the base 11 is installed at one end of the slide cylinder 311, and the gravity of the movable member 24 is greater than the elastic force of the spring 1 32. The end of the slide cylinder 311 opposite to the base 11 is provided with two slide grooves 2 312 for the clamping assembly 33 to slide, and one end of the slide cylinder 311 is provided with a hole for the push rod 12 to extend into.

[0044] When the slide cylinder 311 approaches the base 11 , the push rod 12 gradually extends into the slide cylinder 311 . At this time, the push rod 12 can push the slip ring 34 to block the movement of the slip ring 34 , so that the clamping assembly 33 on the slip ring 34 can extend out of the slide cylinder 311 .

[0045] like Figure 5 to Figure 6As shown, a groove 313 is formed on the inner wall of the slide 311, and a stopper 314 for inserting into the slot 214 is slidably connected inside the groove 313, and the stopper 314 is in a T-shape. When the slide 311 slides on the fixed column 211 to the limit position, the stopper 314 can move down and enter the slot 214 to limit the slide 311.

[0046] like Figure 6 As shown, the outer side of the slip ring 34 is slidably connected to the inner wall of the slide cylinder 311, and the slide cylinder 311 and the slip ring 34 are both provided with grooves for the pressure block 221 to pass through. Two springs 35 are installed at one end of the slip ring 34, and one end of the spring 35 is fixed to one side of the inner wall of the slide cylinder 311. Two springs 36 are installed at the other end of the slip ring 34. The ends of the springs 36 have a bent portion to facilitate the passing of the sling, and the slide cylinder 311 is provided with a groove for the springs 36 to pass through.

[0047] like Figure 4 and Figure 6 As shown, the clamping assembly 33 includes a clamping plate 331, a slide plate 332 and a wedge block 2 333. The clamping plate 331 is in an arc shape, and teeth are installed on the inner side of the clamping plate 331 to increase the friction between the clamping plate 331 and the sling, prevent the sling from sliding on the clamping plate 331, and thus improve the clamping effect of the clamping plate 331 on the sling. A sliding groove 37 is provided at one end of the slip ring 34, and one end of the clamping plate 331 is located in the sliding groove 37. The size of the sliding groove 2 312 is the same as that of the sliding groove 37, and the two correspond to each other. A slide plate 332 is installed on the inner edge of the clamping plate 331, and one end of the slide plate 332 penetrates the slip ring 34 and extends out of the inner side of the slip ring 34. The wedge block 233 is located on the inner side of the slip ring 34 and is installed on the slide plate 332. The wedge block 1 223 is located below the wedge block 233, and the slide plate 332 and the wedge block 233 are both slidably connected in the sliding groove 1 23.

[0048] When the pressure block 221 moves upward under pressure, the mounting plate 222 drives the wedge block 1 223 to move upward, and the wedge block 1 223 drives the clamping plate 331 to approach the fixed column 211 through the slide plate 332 on the wedge block 2 333 to clamp the sling, thereby preventing the sling from sliding on the fixed column 211 due to the tilt of the box body 13 when the box body 13 is lifted, thereby improving the stability of the box body 13 during installation.

[0049] like Figure 6 to Figure 7 As shown, a slide bar 334 is installed at one end of the clamping plate 331 located in the slide groove 37, and the slide bar 334 penetrates the slip ring 34 and extends to the outside of the slip ring 34. The slip ring 34 is provided with a groove for the slide bar 334 to slide, and a mounting block 335 is installed at one end of the slide bar 334, and a spring 2 336 is installed at one end of the mounting block 335. A connecting plate 337 is installed at one end of the spring 2 336, and the connecting plate 337 is installed at one end of the slip ring 34.

[0050] Working principle: During installation, first push the slide 311 toward the push rod 12 so that the spring 1 32 is gradually compressed. During the movement of the slide 311, the push rod 12 gradually extends into the slide 311 and contacts the slip ring 34. As the slide 311 continues to move, the clamp 331 and the spring piece 36 gradually extend out of the slide 311, and the spring 35 is gradually stretched. When the slide 311 moves to the extreme position, the limit piece 314 is inserted into the slot 214, and then the sling is put on the outside of the fixed column 211 and the pressure block 221 is located on the inside of the sling. At the same time, the spring piece 36 clamps the sling to prevent the sling position from shifting.

[0051] After the sling is set, the sling is driven to move up through the external slinging device. At this time, the sling drives the pressure block 221 to move up, and the pressure block 221 drives the wedge block 223 to move up through the mounting plate 222. At this time, the two clamping plates 331 gradually approach the fixing column 211 to clamp the sling on the fixing column 211. The mounting plate 222 contacts the movable part 24 during the upward movement. As the mounting plate 222 continues to move up, the mounting plate 222 drives the movable part 24 to move up. At this time, the top block on the movable part 24 pushes out the limiting member 314, and the protrusion on the movable part 24 extends out. When the limiting member 314 is pushed out, the slide cylinder 311 approaches the protrusion on the movable part 24 under the action of the spring 1 32. When the limiting member 314 is offset from the slot 214, the protrusion on the movable part 24 blocks the slide cylinder 311 from continuing to move.

[0052] When the box body 13 falls to the ground, the extrusion force on the pressure block 221 disappears and begins to move downward. At this time, the wedge block 223 and the movable part 24 move downward synchronously with the pressure block 221. At the same time, the two clamping plates 331 are gradually reset to release the clamping of the sling. When the movable part 24 is reset, under the push of the spring 1 32, the slide 311 begins to move toward the end of the fixed column 211. At this time, the push rod 12 gradually moves out of the slide 311, so that the clamping plate 331 and the spring piece 36 both enter the interior of the slide 311. When the slide 311 moves to the end of the fixed column 211, the sling sleeved on the fixed column 211 is pushed out by the slide 311 to achieve the effect of automatically removing the sling, and there is no need for the staff to manually remove the sling, so as to improve the installation effect of the box body 13.

[0053] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
