Description

Technical Field

[0001] The present application relates to the technical field of substations, and in particular to an American-style substation. Background Art

[0002] As a power facility, American substations are widely used in power grids, power plants and industrial enterprises to provide users with reliable power supply. In order to ensure the safety and reliability of power transmission and distribution, substations need to have efficient heat dissipation performance and a high level of protection. Especially in the field of regional and long-distance power transmission and distribution, the performance of American substations directly affects the stable operation of the system and the life of the equipment, so its design details are crucial.

[0003] In order to achieve the functions of heat dissipation and protection of internal equipment, the existing American substations usually adopt a box structure, in which the main body of the American substation is installed and multiple sets of vents are set. The vents are distributed in the upper and lower parts of the box. In this way, the air outside the box is sucked into the box, and after flowing through the main body of the substation, the heat is taken out of the box, thereby achieving the cooling of the main body of the substation. In addition, in order to meet the needs of different scenarios, some designs use a single large vent or multiple small vents arranged on the entire surface of the box to improve the overall heat dissipation effect.

[0004] However, when there is heavy rain or the ground drainage system is not smooth, causing the ground water to rise, the accumulated water may flow into the box through the vents or the box gaps. In this case, the accumulated water may damage the main body of the American substation and affect its normal operation. This problem is particularly prominent in some low-lying or rainy areas. Summary of the invention

[0005] In order to reduce the possibility of ground water entering and affecting the main body of the substation, the present application provides an American-style substation.

[0006] This application provides an American-style substation, which adopts the following technical solutions:

[0007] An American-style substation, comprising

[0008] A housing, wherein a mounting cavity is formed inside the housing, a connecting groove is formed near the bottom of the housing, and a heat dissipation hole connecting the connecting groove and the mounting cavity is formed on the housing;

[0009] The side wall of the shell is formed with a receiving groove located above and connected to the communicating groove, and the shell is slidably provided with a connecting ring located in the installation cavity;

[0010] A main body, disposed in the shell;

[0011] A carrying plate is slidably connected to the housing and is located in the connecting groove. A plurality of heat dissipation openings are formed evenly spaced up and down on the carrying plate. A supporting column extending into the mounting cavity is arranged on the carrying plate. The connecting ring abuts against the supporting column.

[0012] The outer wall of the shell is provided with a floating bar which slides up and down, and the floating bar is located below the bearing plate and is connected to the bearing plate;

[0013] A blocking plate is arranged at the bottom of the bearing plate, and the blocking plate slides up and down on the housing. When the bearing plate slides upward into the receiving groove, the blocking plate slides in and blocks the heat dissipation hole;

[0014] A diaphragm, connected end to end and arranged in the housing, one end of the diaphragm is connected to the bottom wall of the installation cavity, and the other end is connected to the connecting ring;

[0015] A connecting column capable of turning upside down is hingedly connected inside the shell, and mutually perpendicular fixing columns are arranged at the ends of the connecting column;

[0016] The housing is provided with a driving assembly, and when the carrying plate slides upward into the receiving groove, the driving assembly drives the fixing column to flip into the installation cavity;

[0017] When the bearing plate blocks the heat dissipation hole, the driving component drives the fixing column to flip and leave the installation cavity;

[0018] The connecting ring is formed with a sliding groove for the fixing column to slide up and down, and the connecting ring is connected with a hanging ring located in the sliding groove. When the connecting ring slides upward, the hanging ring is slidably connected to the side wall of the fixing column.

[0019] By adopting the above technical solution, the American substation realizes the intelligent opening and closing of the heat dissipation holes through the structural design of the connecting groove, heat dissipation hole, and receiving groove in the shell, combined with the coordinated work of components such as the bearing plate, connecting ring, floating bar, blocking plate, diaphragm, and connecting column. When the water level of the ground water rises due to heavy rain or blockage of the ground drainage system, the floating bar pushes the bearing plate up with the rising water level, and the heat dissipation port on the bearing plate is exposed. At the same time, the blocking plate slides in and blocks the heat dissipation hole, reducing the possibility of external water entering the installation cavity. At this time, the diaphragm rises with the connecting ring, further enhancing the heat dissipation effect. The connecting column flips into the installation cavity under the action of the driving component, so that when the connecting ring moves downward, the hanging ring can be hung on the fixed column, limiting the downward movement of the connecting ring, which is conducive to maintaining the state of the diaphragm and reducing the possibility of water flow contacting the main body.

[0020] Optionally, the connecting ring is formed with a connecting groove facing the inner wall of the shell and communicating with the sliding groove, the connecting ring is provided with a mounting column located inside the connecting ring, and the hanging ring is hung on the mounting column;

[0021] The connecting ring is provided with a driving spring located in the connecting groove, and the driving spring drives the hanging ring to abut against the top groove wall of the connecting groove.

[0022] By adopting the above technical solution, by arranging the mounting column and the driving spring in the connecting ring, the hanging ring can always keep contact with the top wall of the connecting groove under the action of the spring force, so as to facilitate the hanging ring to be hung on the fixing column. At the same time, when the connecting ring rises, the hanging ring can slide through the fixing column more smoothly.

[0023] Optionally, the mounting column is slidably disposed with a support plate located in the connecting groove, the hanging ring abuts against the bottom of the support plate, the top of the drive spring abuts against the top of the support plate, and the bottom of the drive spring abuts against the wall of the connecting groove.

[0024] By adopting the above technical solution, the setting of the support plate enables the driving spring to drive the hanging ring to move more effectively, while reducing the wear and damage that may be caused by the driving spring directly acting on the hanging ring. The technical effect is that by introducing the support plate, the connection structure between the connecting ring and the mounting column is further optimized, and its overall performance and reliability are improved.

[0025] Optionally, the driving assembly includes an upper push column, a lower push column, a driving column and a driving block;

[0026] The housing is rotatably connected to a hinge shaft, and the connecting column is arranged on the outer peripheral side of the hinge shaft;

[0027] The driving column is slidably connected in the housing, and the driving column is parallel to the hinge axis;

[0028] A driving groove extending along a spiral track is formed on the outer circumference of the hinge shaft, and the driving block is arranged on the outer wall of the driving column, and the driving block is slidably connected in the driving groove;

[0029] The upper push column and the lower push column are respectively arranged on opposite sides of the blocking plate, the upper push column and the lower push column are respectively slid on the shell, and the upper push column is located above the lower push column;

[0030] The upper push column is inclined to form an upper push surface, and the lower push column is inclined to form a lower push surface;

[0031] When the blocking plate slides upward into the receiving groove, after the upper push column passes the driving column, the driving column slides on the lower push surface, driving the driving column to slide, so that the connecting column flips into the installation cavity;

[0032] When the bearing plate blocks the heat dissipation hole, the driving column slides on the upper push surface to drive the driving column to slide, so that the connecting column flips and moves away from the installation cavity.

[0033] By adopting the above technical solution, the automatic flipping of the connecting column is realized through the cooperation of the upper push column, the lower push column, the driving column and the driving block. When the blocking plate rises, the driving column slides on the lower push surface, which is conducive to flipping the connecting column into the installation cavity. The technical effect is that the automatic flipping control of the connecting column is realized by mechanical transmission, without manual intervention, which improves the automation degree and operation efficiency of the substation.

[0034] Optionally, a curved surface structure is formed on a side of the driving block away from the driving column, and the curved surface structure is located in the driving groove.

[0035] By adopting the above technical solution, the setting of the arc surface structure makes the driving block slide more smoothly in the driving groove, reduces friction and wear, and improves the transmission accuracy and reliability. The technical effect is that by optimizing the structure of the driving block, the transmission efficiency and stability of the driving component are further improved, and the service life is extended.

[0036] Optionally, the blocking plate is a telescopic plate structure, and the blocking plate includes a plurality of plate bodies with gradually decreasing widths, and adjacent plate bodies are in sliding contact with each other.

[0037] By adopting the above technical solution, the blocking plate is a telescopic plate structure, which is composed of a plurality of plate bodies with gradually decreasing widths. This design enables the blocking plate to follow the supporting plate to block the heat dissipation holes.

[0038] Optionally, the housing is provided with a sealing ring surrounding the heat dissipation hole, the sealing ring is located on the groove wall of the connecting groove on the side away from the installation cavity, and the sealing ring is in sliding contact with the blocking plate and the bearing plate respectively.

[0039] By adopting the above technical solution, the sealing ring is in sliding contact with the blocking plate and the bearing plate respectively, forming an effective sealing barrier, reducing the possibility of external dust, moisture and water flow entering the installation cavity. The technical effect is that by adding a sealing ring, the sealing performance of the substation is further improved, protecting the normal operation and safe use of the internal equipment of the substation.

[0040] Optionally, the housing is formed with a receiving groove located at the bottom of the installation cavity and connected thereto, and the bottom of the diaphragm is connected to a groove wall at the bottom of the receiving groove.

[0041] By adopting the above technical solution, a receiving groove connected to the installation cavity is provided at the bottom of the housing, and the bottom of the diaphragm is connected to the groove wall at the bottom of the receiving groove, and the diaphragm is received by the receiving groove during use. At the same time, the receiving groove also plays a role in collecting accumulated water, further reducing the possibility of accumulated water contacting the main body.

[0042] Optionally, the shell is provided with a one-way water outlet valve connected to the receiving groove, and water between the diaphragm and the wall of the receiving groove is discharged through the one-way water outlet valve.

[0043] By adopting the above technical solution, a one-way water outlet valve is set on the storage tank. When there is too much water inside the substation, the water can be automatically discharged to the external environment through the one-way water outlet valve. This design reduces the risk of damage and corrosion to the internal equipment of the substation caused by accumulated water, and also reduces the maintenance burden of operation and maintenance personnel.

[0044] In summary, the present application includes at least one of the following beneficial effects:

[0045] 1. When the water level rises due to heavy rain or blockage of the ground drainage system, the floating bar pushes the supporting plate up with the rising water level, exposing the heat dissipation holes on the supporting plate. At the same time, the blocking plate slides in and blocks the heat dissipation holes, reducing the possibility of external water entering the installation cavity. At this time, the diaphragm rises with the connecting ring, further enhancing the heat dissipation effect. The connecting column flips into the installation cavity under the action of the driving component, so that when the connecting ring moves downward, the hanging ring can be hung on the fixed column, limiting the downward movement of the connecting ring, which is conducive to maintaining the state of the diaphragm and reducing the possibility of water contact with the main body;

[0046] 2. The blocking plate is a telescopic plate structure, which is composed of multiple plates with gradually decreasing widths. This design enables the blocking plate to follow the load-bearing plate to block the heat dissipation holes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-7 This application is described in further detail.

[0056] The embodiment of the present application discloses an American-style substation.

[0057] The inventor of the present application has found that when heavy rain or ground drainage system blockage causes the water level on the ground to rise, the accumulated water may enter the box through the vents or the gaps on the box, affecting the normal use of the main body of the American substation. To this end, the present application mainly adopts the following scheme to achieve the effect of reducing the possibility of ground water entering the box and affecting the main body of the substation. The present invention is further described in detail below.

[0058] See also Figure 1 and Figure 2 An American-style substation provided in an embodiment of the present application includes a housing 1 and a main body 3. An installation cavity 11 is formed inside the housing 1, and the main body 3 is fixed to the housing 1 and located in the installation cavity 11.

[0059] Specifically, the housing 1 includes a plate wall made of various materials, such as galvanized steel plate, stainless steel, cold-rolled plate or aluminum alloy. The surface of the housing 1 is sprayed with plastic to enhance corrosion resistance.

[0060] A connecting groove 12 is formed in the housing 1, and the connecting groove 12 is located near the bottom of the housing. The housing 1 forms heat dissipation holes 13 corresponding to the connecting grooves 12, and the heat dissipation holes 13 are respectively connected to the connecting grooves 12 and the installation cavity 11. A receiving groove 14 is formed inside the side wall of the housing 1, and the receiving groove 14 is located above the connecting groove 12, and the receiving groove 14 is connected to the connecting groove 12.

[0061] The housing 1 is provided with a bearing plate 4, which is made of stainless steel and is slidably connected to the connecting groove 12. The bearing plate 4 is formed to match the size of the connecting groove 12. The bearing plate 4 is formed with a heat dissipation port 41, which has multiple heat dissipation ports 41 and is evenly spaced up and down.

[0062] The outer wall of the housing 1 is slidably connected with a floating bar 15, which is located below the bearing plate 4 and is fixedly connected to the bearing plate 4. When a heavy rainstorm or a road drainage system is blocked, causing the water level of the road to rise, the accumulated water contacts the floating bar 15, and as the accumulated water level continues to rise, the floating bar 15 drives the bearing plate 4 to move upward, and at this time the bearing plate 4 gradually slides away from the heat dissipation hole 13, and the bearing plate 4 slides into the receiving groove 14.

[0063] See also Figure 2 and Figure 3 The housing 1 is provided with a blocking plate 5, which is a telescopic plate structure. The blocking plate 5 includes a plurality of nested plates 51 with gradually decreasing widths. Adjacent plates 51 are slidably connected to each other. A limiting block is fixedly connected to the outer wall of the inner plate 51, and a limiting groove for the limiting block to slide up and down is formed on the inner wall of the adjacent outer plate 51. The bottom of the outermost plate 51 is fixedly connected to the bottom wall of the connecting groove 12, and the top of the innermost inner plate is fixedly connected to the bottom of the bearing plate 4. The length of the plate 51 is adapted to the width of the connecting groove 12, and the side wall of the plate 51 is in sliding contact with the side wall of the connecting groove 12. When the supporting plate 4 slides upward, the supporting plate 4 drives the innermost plate body 51 to slide upward, until the limiting block of the innermost plate body 51 abuts against the top groove wall of the limiting groove of the connected outer plate body 51, the inner plate body 51 drives the adjacent outer plate body 51 to move upward, and so on. The plate body 51 continuously follows the supporting plate 4 to move upward, thereby blocking the heat dissipation hole 13 and reducing the possibility of water entering the installation cavity 11 through the heat dissipation hole 13 when the water level rises.

[0064] At the same time, the housing 1 is fixedly connected with a sealing ring 16, which is made of rubber material and is located on the groove wall of the connecting groove 12 away from the installation cavity 11. The sealing ring 16 surrounds the heat dissipation hole 13. The sealing ring 16 is in sliding contact with the blocking plate 5 and the bearing plate 4 respectively to achieve a sealing effect, further reducing the possibility of water entering the installation cavity 11.

[0065] The housing 1 is provided with a connecting ring 2 located in the installation cavity 11, which is slidable up and down. The connecting ring 2 is in a "mouth"-shaped structure. The supporting plate 4 is fixedly connected to a support column 42 near the installation cavity 11. The support column 42 extends into the installation cavity 11, and the bottom of the connecting ring 2 abuts against the top of the support column 42. When the supporting plate 4 slides up and down, the supporting plate 4 drives the connecting ring 2 to move up and down. At this time, the connecting ring 2 slides in contact with the cavity wall around the installation cavity 11. The housing 1 is provided with a diaphragm 6, which is connected end to end and is located in the installation cavity 11. A receiving groove 17 is formed on the bottom cavity wall of the installation cavity 11, and the receiving groove 17 extends along a "mouth"-shaped trajectory to accommodate the diaphragm 6. One end of the diaphragm 6 is fixedly connected to the bottom groove wall of the receiving groove 17, and the other end is fixedly connected to the bottom of the connecting ring 2. When the connecting ring 2 moves upward, it drives the diaphragm 6 to move upward. At this time, the diaphragm 6 surrounds the main body 3, reducing the possibility of the accumulated water infiltrating into the installation cavity 11 contacting the main body 3.

[0066] See also Figure 1 and Figure 2 The housing 1 is fixedly mounted with a one-way water outlet valve 18, which is located on the groove wall of the receiving groove 17 near the bottom, and is connected to the receiving groove 17. When accumulated water enters the installation cavity 11, the accumulated water is collected in the receiving groove 17. When the amount of accumulated water is large, the water flow is discharged through the one-way water outlet valve 18 under the action of water pressure.

[0067] See also Figure 4 and Figure 5 A hinge groove is formed on the inner wall of the installation cavity 11, and the housing 1 is rotatably connected to the hinge shaft 7, and the hinge shaft 7 is located in the hinge groove. A connecting column 71 is fixedly connected to the outer peripheral side of the hinge shaft 7, and the connecting column 71 can be turned up and down. A fixed column 72 is fixedly connected to the end of the connecting column 71 away from the hinge shaft 7, and the fixed column 72 and the connecting column 71 are perpendicular to each other. When the connecting column 71 turns upward, the connecting column 71 drives the fixed column 72 to turn into the installation cavity 11, and at this time, the angle between the fixed column 72 and the connecting column 71 is set upward.

[0068] See also Figure 6 and Figure 7 The housing 1 is provided with a driving assembly 8, and the carrying plate 4 slides upward into the receiving groove 14 (the receiving groove 14 is Figure 2 When the mounting cavity 11 is in the middle, the driving assembly 8 drives the fixing column 72 to flip into the mounting cavity 11. The bearing plate 4 blocks the heat dissipation hole 13 (the heat dissipation hole 13 is in the middle). Figure 2 When the fixing post 72 is turned over and separated from the mounting cavity 11, the driving assembly 8 drives the fixing post 72 to turn over and separate from the mounting cavity 11.

[0069] The driving assembly 8 includes an upper push column 81, a lower push column 82, a driving column 83 and a driving block 84. The lower push column 82 is a square column structure, the upper push column 81 is a square column structure, and the driving column 83 is a square column structure. The upper push column 81 and the lower push column 82 extend along an "L"-shaped track respectively, and the upper push column 81 and the lower push column 82 are respectively fixedly connected to the vertical side walls on the opposite sides of the bearing plate 4. The upper push column 81 and the lower push column 82 are respectively slidably connected to the housing 1, and the upper push column 81 is located above the lower push column 82.

[0070] See also Figure 3 and Figure 5 The upper push column 81 is inclined at one side away from the carrier plate 4 to form an upper push surface 811, and the lower push column 82 is inclined at one side away from the carrier plate 4 to form a lower push surface 821. A driving groove 73 is formed on the outer peripheral side of the hinge shaft 7, and the driving groove 73 extends along a spiral track. The driving column 83 is slidably connected to the side wall of the housing 1, and the driving column 83 slides in the horizontal direction, and the driving column 83 is parallel to the hinge shaft 7.

[0071] See also Figure 7 The driving block 84 is fixed on the outer peripheral side of the driving column 83 , and a curved surface structure is formed on the side of the driving block 84 away from the driving column 83 . The driving block 84 slides in the driving groove 73 , and the curved surface structure of the driving block 84 is located in the driving groove 73 .

[0072] See also Figure 3 and Figure 5 , the blocking plate 5 slides upward into the receiving groove 14 (the receiving groove 14 is Figure 2 When the hinge 7 is in the middle, the upper push column 81 passes through the driving column 83 first, and then the lower push column 82 slides upward and approaches the driving column 83; then the driving column 83 slides on the lower push surface 821, and at this time the lower push column 82 pushes the driving column 83 to slide in the horizontal direction, and then the driving column 83 drives the driving block 84 to slide in the driving groove 73, so that the hinge shaft 7 rotates, and drives the fixing column 72 to flip into the installation cavity 11 through the connecting column 71.

[0073] When the carrier plate 4 blocks the heat dissipation hole 13 (the heat dissipation hole 13 is Figure 2 When the hinge 70 is in the state of rotation and the hinge 70 is in the state of rotation, the lower push column 82 first passes through the driving column 83, and then the upper push column 81 slides downward and approaches the driving column 83; then the driving column 83 slides on the upper push surface 811, and at this time the upper push column 81 pushes the driving column 83 to slide in the reverse direction in the horizontal direction, and then the driving column 83 drives the driving block 84 to slide in the driving groove 73, so that the hinge shaft 7 rotates in the reverse direction, and drives the fixing column 72 to flip and detach from the installation cavity 11 through the connecting column 71.

[0074] The connecting ring 2 is formed with a slide groove 26 extending in the vertical direction. When the connecting ring 2 slides up and down, the fixing column 72 slides up and down in the slide groove 26. The connecting ring 2 is formed with a connecting groove 21. The connecting groove 21 is located on a side of the groove wall of the slide groove 26 facing the inner wall of the housing 1, and the connecting groove 21 is connected to the slide groove 26. The connecting ring 2 is fixedly connected with a mounting column 22. The mounting column 22 is located in the connecting groove 21 and is located near the notch. The connecting ring 2 is provided with a hanging ring 25. The hanging ring 25 is hung on the mounting column 22, and a part of the hanging ring 25 protrudes out of the connecting groove 21.

[0075] The mounting column 22 is slidably connected to a support plate 23, which is located in the connection groove 21. The hanging ring 25 abuts against the top of the support plate 23, and the connection ring 2 is provided with a driving spring 24, the top of the driving spring 24 abuts against the bottom of the support plate 23, and the bottom of the driving spring 24 abuts against the bottom groove wall of the connection groove 21. When the driving spring 24 is elastically released, it pushes the support plate 23 to move upward, so that the top outer wall of the connection ring 2 abuts against the top groove wall of the connection groove 21.

[0076] When the connecting ring 2 slides upward, the hanging ring 25 is slidably connected to the side wall of the fixed column 72; then, when the connecting ring 2 continues to move upward, it is fixed to drive the hanging ring 25 to move downward, and drives the support plate 23 to move downward, so that the driving spring 24 enters the extrusion state; then, when the connecting ring 2 moves away from the fixed column 72, the hanging ring 25 can tilt and flip downward, so that the hanging ring 25 can pass through the fixed column 72. After the hanging ring 25 moves away from the fixed column 72, the driving spring 24 is elastically released, pushing the support plate 23 to move upward, so that the top of the hanging ring 25 abuts against the top groove wall of the connecting groove 21, and the hanging ring 25 is in a horizontal state. Afterwards, when the hanging ring 25 moves downward, the hanging ring 25 is hung on the fixed column 72. At this time, the fixed column 72 limits the downward movement of the connecting ring 2 through the hanging ring 25, which is conducive to maintaining the state of the diaphragm 6 and reducing the possibility that the accumulated water passes over the diaphragm 6 and enters the installation groove to affect the main body 3 when the bearing plate 4 moves up and down with the water level. Finally, when the supporting plate 4 slides downward to the state before the water rises, the connecting column 71 drives the fixing column 72 to flip away from the installation cavity 11. At this time, the fixing column 72 is separated from the hanging ring 25, so that the connecting ring 2 can move downward, reducing the possibility of the diaphragm 6 affecting the normal maintenance of the American substation.

[0077] The implementation principle of an American-style substation in the embodiment of the present application is:

[0078] When heavy rain or blockage of the ground drainage system causes the water level on the ground to rise, the accumulated water drives the supporting plate 4 to move upward through the floating bar 15, and the supporting plate 4 drives the blocking plate 5 to block the heat dissipation hole 13. Then the supporting plate 4 drives the diaphragm 6 to move upward through the connecting ring 2, surrounding the main body 3, thereby limiting the possibility of water entering the installation cavity 11 contacting the main body 3.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
