Description

Technical Field

[0001] This invention relates to the field of substation technology, and in particular to an outdoor modular substation based on a smart grid. Background Technology

[0002] An outdoor prefabricated substation is a complete power distribution unit that integrates high-voltage switchgear, distribution transformers, low-voltage switchgear, power metering equipment, and reactive power compensation devices according to a specific wiring scheme. It is pre-installed in a waterproof, dustproof, rustproof, and sealed steel structure enclosure. Simply put, it's like a mobile "mini substation," pre-manufactured, installed, and commissioned in a factory, then transported to the power consumption site. Only high-voltage cable connection, low-voltage cable connection, and foundation fixing are required before it can be put into operation. In the summer in southern my country, the air is humid. In order to ensure the effectiveness of ventilation and heat dissipation, ventilation holes are usually installed. During ventilation and heat dissipation, humid air can easily enter the substation. The moisture in the humid air will adhere to the surface of the equipment, forming a conductive path, reducing the insulation resistance, and may cause leakage, short circuit or even equipment burnout, seriously threatening personal safety and power grid safety.

[0003] For example, the "box-type substation with dehumidification and drying function" published under the number "CN219350991U" can deliver outside air to the drying box through a ventilation fan and connecting pipe, and the desiccant in the drying box can dehumidify and dry the moisture in the air.

[0004] In existing technologies, silica gel desiccant is often used to dry the air entering the prefabricated substation. During the drying process, when the air circulates, the desiccant near the air inlet will preferentially absorb moisture and quickly become saturated, resulting in uneven moisture absorption by the desiccant. After a period of use, the effective moisture absorption thickness of the desiccant will decrease, thus affecting the moisture absorption effect. This allows humid air to enter the substation, threatening personal safety and power grid safety. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor modular substation based on a smart grid, which enables the agitator to rotate and agitate the desiccant, ensuring the uniformity of moisture absorption by the desiccant. Simultaneously, as the agitator moves upward and rotates, it facilitates the movement of desiccant that was previously far from the air inlet to a position closer to the air inlet, improving the uniformity of desiccant mixing, reducing uneven moisture absorption between the upper and lower layers of desiccant, preventing a decrease in the effective moisture absorption thickness of the desiccant after a period of use, and improving the moisture absorption effect, thereby solving the problems mentioned in the background art.

[0008] Preferably, the agitation assembly includes a stirring cover fixedly connected to the bottom of the outer wall of the moving rod, an elastic membrane fixedly connected to the inner side of the stirring cover, and a push plate fixedly connected to the inner side of the elastic membrane.

[0009] Preferably, a bottom tube is fixedly connected to the top of the push plate, an insertion rod is fixedly connected to the top of the bottom tube, a top tube is slidably connected to the top of the insertion rod, a limiting cylinder is slidably connected to the outside of the top tube, a connecting frame is fixedly connected to the outer wall of the limiting cylinder, and the connecting frame is rotatably connected to the inner side of the drying cylinder at a position away from the limiting cylinder.

[0010] Preferably, the limiting cylinder is internally configured with a limiting component, which includes a limiting plate fixedly connected to the top of the jacking pipe, and a limiting block slidably connected inside the limiting cylinder. A U-shaped spring is fixedly connected between the limiting block and the limiting cylinder. A bending frame is fixedly connected to the outside of the limiting block and slides inside the limiting cylinder. An expansion bladder is fixedly connected between the bending frame and the limiting cylinder. An inner rod frame is internally configured inside the jacking pipe. A compression bladder is fixedly connected to the bottom side of the top position of the inner rod frame. A flexible pipe is fixedly inserted between the compression bladder and the expansion bladder. The bottom of the inner rod frame is fixedly connected to the stirring hood.

[0011] Preferably, the bottom of the limiting block has rounded corners.

[0012] Preferably, the inner side of the jacking pipe is provided with a quick-release assembly, which includes a movable frame slidably connected inside the inner rod frame. The top of the movable frame extends out from the inner rod frame, and the bottom of the top position of the movable frame is inclined. A limiting rod is fixedly connected to the bottom of the movable frame, and the limiting rod is slidably connected to the inner rod frame. The quick-release assembly also includes a bottom ring fixed inside the bottom pipe, a top ring fixedly connected to the inner side of the jacking pipe, and an elastic rope fixedly connected between the bottom ring and the top ring.

[0013] Preferably, a magnetic block is fixed inside the inner frame near the movable frame, and the movable frame near the magnetic block is made of iron.

[0014] Preferably, a regeneration tube is fixedly connected to the top of the housing, a vent pipe is inserted into the inside of the regeneration tube, and an electric heating rod is arranged inside the regeneration tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. With the combined action of the spiral groove and the guide slider, the connecting rod and the moving rod can rotate when they move up and down, and the stirring component rotates along with them, which is beneficial to stirring the desiccant, improving the uniformity of moisture absorption by the desiccant, and thus ensuring the moisture absorption effect of the desiccant; 2. As the stirring hood moves upward and rotates, it lifts the desiccant located far from the air inlet, making it easier for the desiccant at the bottom to reach the top layer. This, in turn, makes it easier for the desiccant located far from the air inlet to reach the position closer to the air inlet, improving the uniformity of desiccant mixing, reducing uneven moisture absorption between the upper and lower layers of desiccant, and preventing the effective moisture absorption thickness of the desiccant from decreasing after a period of use. This improves the moisture absorption effect and reduces the amount of humid air entering the substation. 3. The bottom of the push plate will separate from the stirring cover, and the elastic membrane will stretch and deform, which can tilt the position of the elastic membrane, making it easier for the lifted desiccant to fall on the upper part of the desiccant. This further facilitates the desiccant that was originally far away from the air inlet to reach the position closer to the air inlet, improves the uniformity of desiccant mixing, reduces uneven moisture absorption between the upper and lower layers of desiccant, and prevents the effective moisture absorption thickness of the desiccant from decreasing after a period of use, thereby improving the moisture absorption effect. 4. The bottom pipe and the top pipe are far apart from each other. The elastic rope is stretched and deformed. Before the bottom of the compression bladder contacts the limiting plate, the top of the moving frame contacts the inner side of the limiting plate. At this time, it is limited but does not block the bottom ring. Under the elastic force of the elastic rope, the pushing plate quickly separates from the stirring hood and the elastic membrane deforms, which makes it easy to quickly throw the lifted desiccant to the surface of the desiccant. This further facilitates the desiccant that was originally far away from the air inlet to reach the position near the air inlet, improving the uniformity of desiccant mixing.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 12 This invention provides a technical solution: an outdoor modular substation based on a smart grid, comprising a housing 1, a rain cover 2 fixed to the top of the housing 1, internal components of the substation configured inside the housing 1, an air inlet pipe 3 fixedly connected to the top of the housing 1, a fan assembly 4 for airflow inside the air inlet pipe 3, and an exchange assembly 5 configured outside the air inlet pipe 3. The exchange assembly 5 includes a motor 51 fixed to the top of the housing 1, a base plate 52 fixed to the outer wall of the output shaft of the motor 51, and an air outlet pipe configured at the bottom of the housing 1. The fan assembly 4 is driven by a motor to rotate the fan blades. When the substation is used for ventilation and heat dissipation, the rotation of the fan blades of the fan assembly 4 facilitates air to enter from the air inlet pipe 3 and exit from the air outlet pipe to dissipate heat for the substation.

[0021] The prefabricated substation also includes drying components 6 disposed on both sides of the base plate 52. The drying components 6 include drying cylinders 61 fixed on both sides of the base plate 52. Ventilation plates 62 are fixed at both the top and bottom ends of the drying cylinder 61. Ventilation plates 62 have ventilation holes to facilitate air circulation, but the ventilation holes are smaller than the particle size of silica gel desiccant. A small rod 63 is fixedly connected to the bottom of the upper ventilation plate 62. A moving rod 64 is movably connected to the bottom of the small rod 63. A connecting rod 65 is fixed in a ring array on the outer wall of the moving rod 64. A moving ring 66 is rotatably connected to the end of the connecting rod 65. A cylinder for reducing friction can be configured at the end of the connecting rod 65. The moving ring 66 moves up and down. A spiral groove is opened on the outer wall of the small rod 63. A guide slider 67 is fixed on the inner wall of the moving rod 64. The guide slider 67 moves inside the spiral groove. The prefabricated substation also includes an agitation assembly 7 disposed outside the moving rod 64, which is used to agitate the desiccant inside the drying cylinder 61.

[0022] A top plate 53 is fixedly connected to the top of the output shaft of motor 51. The inner side of the top plate 53 is fixed to the drying cylinder 61. The top of the drying cylinder 61 is flush with the top of the top plate 53, and the bottom of the drying cylinder 61 is flush with the bottom of the bottom plate 52. An electric telescopic rod 10 is fixedly connected inside the top plate 53. A lifting rod 11 is fixedly connected to the output shaft of the electric telescopic rod 10. The two sides of the lifting rod 11 extend into the interior of the drying cylinder 61 and are fixed to the moving ring 66. A flexible membrane 12 is fixed between the outside of the lifting rod 11 and the drying cylinder 61. The design of the flexible membrane 12 does not affect the sealing between the lifting rod 11 and the drying cylinder 61.

[0023] By adopting the above technical solution, when ventilation and heat dissipation are carried out, the output shaft of motor 51 can rotate to make one of the drying cylinders 61 rotate above the air inlet pipe 3. At this time, the desiccant inside the drying cylinder 61 dehumidifies the air that is introduced, preventing humid air from entering the substation and causing a conductive path, reducing insulation resistance, and potentially causing leakage, short circuit or even equipment burnout.

[0024] The electric telescopic rod 10 is periodically extended and retracted via its output shaft, allowing the lifting rod 11 to move up and down along with the moving ring 66. During this process, the connecting rod 65 moves the moving rod 64 in the vertical direction. At this time, a relative displacement occurs between the moving rod 64 and the small rod 63. With the cooperation of the spiral groove and the guide slider 67, the connecting rod 65 and the moving rod 64 rotate as they move up and down, and the agitating component 7 rotates accordingly. This helps to agitate the desiccant, improves the uniformity of moisture absorption by the desiccant, and thus ensures the moisture absorption effect of the desiccant.

[0025] A flexible rubber membrane can be installed between the top of the moving rod 64 and the small rod 63, and the size of the flexible rubber membrane is set to be large so as not to affect the movement of the moving rod 64.

[0026] The stirring assembly 7 includes a stirring cover 71 fixedly connected to the bottom of the outer wall of the moving rod 64.

[0027] By adopting the above technical solution, the mixing hood 71 is set to a relatively large volume. When the output shaft of the electric telescopic rod 10 is extended, the mixing hood 71 is located near the lower ventilation plate 62. At this time, the mixing hood 71 is located at the desiccant position away from the air inlet. When the output shaft of the electric telescopic rod 10 begins to retract, the mixing hood 71 moves upward and rotates, lifting the desiccant position away from the air inlet. This facilitates the lower layer of desiccant to reach the upper layer, thereby facilitating the movement of the desiccant from the original position away from the air inlet to the position closer to the air inlet. This improves the uniformity of desiccant mixing, reduces uneven moisture absorption between the upper and lower layers of desiccant, and prevents the effective moisture absorption thickness of the desiccant from decreasing after a period of use. This improves the moisture absorption effect and reduces the entry of humid air into the substation.

[0028] An elastic membrane 72 is fixedly connected to the inner side of the stirring shroud 71. A pusher plate 73 is fixedly connected to the inner side of the elastic membrane 72. The elastic membrane 72 has a large elastic force. A bottom tube 74 is fixedly connected to the top of the pusher plate 73. An insertion rod 75 is fixedly connected to the top of the bottom tube 74. A top tube 76 is slidably connected to the top of the insertion rod 75. A limiting cylinder 77 is slidably connected to the outside of the top tube 76. A connecting frame 78 is fixedly connected to the outer wall of the limiting cylinder 77. The connecting frame 78 is rotatably connected to the inner side of the drying cylinder 61 at a position away from the limiting cylinder 77. A limiting component 8 is disposed inside the limiting cylinder 77. The limiting component 8 includes components fixedly connected to the top tube. The limiting plate 81 at the top of the 76 and the limiting component 8 also include a limiting block 82 slidably connected inside the limiting cylinder 77. A U-shaped spring piece 83 is fixedly connected between the limiting block 82 and the limiting cylinder 77. A bending frame 84 is fixedly connected to the outside of the limiting block 82. The bending frame 84 slides inside the limiting cylinder 77. An expansion bladder 85 is fixedly connected between the bending frame 84 and the limiting cylinder 77. An inner rod frame 86 is configured inside the top tube 76. A compression bladder 87 is fixedly connected to the bottom side of the top position of the inner rod frame 86. A flexible pipe 88 is fixedly inserted between the compression bladder 87 and the expansion bladder 85. The bottom of the inner rod frame 86 is fixedly connected to the stirring cover 71.

[0029] The bottom of the limiting block 82 has rounded corners.

[0030] It should be noted that when the stirring shroud 71 lifts the desiccant located away from the air inlet, the height of the lifting shroud is greater than the thickness of the desiccant, thus allowing some of the desiccant to be lifted above the top layer of desiccant.

[0031] When the output shaft of the electric telescopic rod 10 begins to retract, the stirring shroud 71 rotates and moves upward, lifting the desiccant away from the air inlet. Simultaneously, the bottom tube 74, insertion rod 75, and top tube 76 move upward. Because the bottom of the limiting block 82 has rounded corners, the limiting plate 81, moving upward with the top tube 76, can press against the bottom of the limiting block 82, allowing the limiting plate 81 to reach above the limiting block 82. When the output shaft of the electric telescopic rod 10 extends, causing the stirring shroud 71 to move downward, the limiting block 82... When in use, the top tube 76 and the limiting plate 81 cannot move downwards. At this time, because the stirring hood 71 will move downwards, the bottom of the push plate 73 will separate from the stirring hood 71, and the elastic membrane 72 will stretch and deform, which can make the position of the elastic membrane 72 tilted, so that the lifted desiccant falls on the upper position of the desiccant. This further facilitates the desiccant that was originally far away from the air inlet to reach the position near the air inlet, improves the uniformity of desiccant mixing, reduces the uneven moisture absorption between the upper and lower layers of desiccant, and prevents the effective moisture absorption thickness of the desiccant from decreasing after a period of use, thereby improving the moisture absorption effect.

[0032] After the elastic membrane 72 deforms, as the stirring shroud 71 continues to move downward, the inner rod frame 86 moves downward as well, so that the bottom of the compression bladder 87 contacts the limiting plate 81, allowing the medium inside the compression bladder 87 to enter the interior of the expansion bladder 85 through the flexible pipe 88. At this time, the bending frame 84 moves with the limiting block 82, so that the limiting block 82 is no longer limited. Under the elastic force of the elastic membrane 72, the top pipe 76 and the push plate 73 descend, and the push plate 73 returns to its original position and approaches the stirring shroud 71.

[0033] The inner side of the jacking tube 76 is equipped with a quick-release assembly 9. The quick-release assembly 9 includes a movable frame 91 that is slidably connected inside the inner rod frame 86. The top of the movable frame 91 extends out of the inner rod frame 86, and the bottom of the top position of the movable frame 91 is inclined. The bottom of the movable frame 91 is fixedly connected to a limiting rod 92, which is slidably connected to the inner rod frame 86. The quick-release assembly 9 also includes a bottom ring 93 fixed inside the bottom tube 74. The inner side of the jacking tube 76 is fixedly connected to a top ring 94. An elastic rope 95 is fixedly connected between the bottom ring 93 and the top ring 94. A magnetic block 96 is fixed inside the inner rod frame 86 near the movable frame 91. The position of the movable frame 91 near the magnetic block 96 is made of iron. Under the action of magnetic force, in the initial stage, the limiting rod 92 is in a state of blocking the bottom ring 93.

[0034] When the limiting plate 81 is prevented from moving downward by the limiting block 82, the limiting rod 92 allows the bottom ring 93 and bottom tube 74 to move downward. The bottom of the push plate 73 will not separate from the stirring hood 71. At this stage, the elastic membrane 72 does not deform. Since the bottom tube 74 and the top tube 76 are far apart, the elastic rope 95 stretches and deforms. Before the bottom of the compression bladder 87 contacts the limiting plate 81, the top of the moving frame 91 contacts the inner side of the limiting plate 81. At this time, it is limited but does not block the bottom ring 93. Under the elastic force of the elastic rope 95, the push plate 73 quickly separates from the stirring hood 71 and the elastic membrane 72 deforms, which facilitates the rapid throwing of the lifted desiccant to the surface of the desiccant. This further facilitates the desiccant that was originally far from the air inlet to reach the position near the air inlet, improving the uniformity of the desiccant mixing. Then the stirring hood 71 continues to move downward, and the bottom of the compression bladder 87 will contact the limiting plate 81.

[0035] The desiccant is regenerated by periodically rotating the output shaft of motor 51 by 180 degrees. This allows the drying component 6, which was originally located at the air inlet pipe 3, to move to the regeneration pipe 13.

[0036] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 7 A regeneration tube 13 is fixedly connected to the top of the housing 1. A vent tube 14 is inserted into the inside of the regeneration tube 13. An electric heating rod 15 is installed inside the regeneration tube 13.

[0037] By adopting the above technical solution, the bottom of the ventilation pipe 14 is connected to the air outlet pipe. After the air absorbs the heat inside the substation, it enters the interior of the regeneration pipe 13. The high-temperature air blows onto the silica gel desiccant, causing the silica gel desiccant to regenerate.

[0038] It should be noted that a temperature sensor is installed inside the regeneration tube 13, and the heating rod 15 provides auxiliary heating when the temperature is insufficient.

[0039] It should be noted that the air entering the chamber 1 has low humidity, and the air discharged from the regeneration pipe 13 has low humidity, which ensures the regeneration effect.

[0040] It should be noted that during regeneration, as the output shaft of the electric telescopic rod 10 extends and retracts, the lifting rod 11 moves up and down. With the cooperation of the stirring component 7, the quick-release component 9, and the limiting component 8, the desiccant to be regenerated can be stirred during regeneration. During stirring, the lower layer of desiccant can be carried to the upper layer, ensuring uniform stirring and avoiding uneven regeneration that would result in poor subsequent drying effect. The ventilation plate 62 at the top can also filter dust. During regeneration, air flows from bottom to top, which facilitates the removal of impurities filtered on the ventilation plate 62.

[0041] The elastic membrane 72, flexible membrane 12, flexible rubber membrane and elastic cord 95 are all made of high temperature resistant materials, and the magnetic block 96 is made of high temperature resistant magnetic material.

[0042] Working principle: During ventilation and heat dissipation, the output shaft of motor 51 rotates, causing one of the drying cylinders 61 to rotate above the air inlet pipe 3. At this time, the desiccant inside the drying cylinder 61 dehumidifies the incoming air. The output shaft of the electric telescopic rod 10 extends and retracts, causing the lifting rod 11 to move up and down along with the moving ring 66. During this process, the connecting rod 65 moves the moving rod 64 in the vertical direction. At this time, a relative displacement occurs between the moving rod 64 and the small rod 63. Under the cooperation of the spiral groove and the guide slider 67, the connecting rod 65 and the moving rod 64 rotate as they move up and down, and the stirring component 7 also rotates accordingly. Rotation facilitates agitation of the desiccant, improving the uniformity of moisture absorption. When the output shaft of the electric telescopic rod 10 is extended, the stirring hood 71 is located near the lower ventilation plate 62. At this time, the stirring hood 71 is located at the desiccant position away from the air inlet. When the output shaft of the electric telescopic rod 10 begins to retract, the stirring hood 71 moves upward and rotates, lifting the desiccant position away from the air inlet. This facilitates the movement of the desiccant from the bottom layer to the upper layer, thereby making it easier for the desiccant position that was originally far from the air inlet to move to the position near the air inlet. This improves the uniformity of desiccant mixing and reduces uneven moisture absorption between the upper and lower layers of desiccant.

[0043] When the output shaft of the electric telescopic rod 10 begins to retract, the stirring shroud 71 rotates and moves upward, lifting the desiccant away from the air inlet. Simultaneously, the bottom tube 74, insertion rod 75, and top tube 76 move upward. Because the bottom of the limiting block 82 has rounded corners, the limiting plate 81, moving upward with the top tube 76, can press against the bottom of the limiting block 82, allowing the limiting plate 81 to reach above the limiting block 82. When the output shaft of the electric telescopic rod 10 extends, causing the stirring shroud 71 to move downward... During movement, under the restriction of the limiting block 82, the top pipe 76 and the limiting plate 81 cannot move downwards. At this time, as the stirring hood 71 moves downwards, the bottom of the pushing plate 73 will separate from the stirring hood 71, and the elastic membrane 72 will stretch and deform, which can make the position of the elastic membrane 72 tilt, so that the lifted desiccant falls on the upper position of the desiccant, further facilitating the desiccant that was originally far away from the air inlet to reach the position near the air inlet, improving the uniformity of desiccant mixing, and reducing the uneven moisture absorption between the upper and lower layers of desiccant.

[0044] When the limiting plate 81 is prevented from moving downward by the limiting block 82, the limiting rod 92 allows the bottom ring 93 and the bottom tube 74 to move downward. The bottom of the push plate 73 will not separate from the stirring hood 71. At this stage, the elastic membrane 72 does not deform. Since the bottom tube 74 and the top tube 76 are far apart, the elastic rope 95 stretches and deforms. Before the bottom of the compression bladder 87 contacts the limiting plate 81, the top of the moving frame 91 contacts the inner side of the limiting plate 81. At this time, it is limited but does not block the bottom ring 93. Under the elastic force of the elastic rope 95, the push plate 73 quickly separates from the stirring hood 71 and the elastic membrane 72 deforms, which facilitates the rapid throwing of the lifted desiccant to the surface of the desiccant, further facilitating the desiccant that was originally far from the air inlet to reach the position close to the air inlet.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
