Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of voltage regulator, in particular to an improved dry-type energy-saving voltage regulator. BACKGROUND

[0002] The dry-type energy-saving voltage regulator is a power device integrating high-efficiency energy saving and intelligent voltage regulation functions.

[0003] When using the dry-type energy-saving voltage regulator, the device needs to be connected to the power supply first, and then the required output voltage parameters are set through the control panel or system. During the operation of the device, the ventilation structure adopts the design of the air inlet at the bottom and the air outlet at the top, which utilizes the density difference of cold and hot air to make the cold air sucked from the bottom and the hot air discharged from the top, forming natural convection, thereby effectively taking away the heat generated during the operation of the device and ensuring the stable and reliable operation of the device.

[0004] However, after the hot air discharged from adjacent single dry-type energy-saving voltage regulators forms backflow due to space compression, the heat inside the voltage regulator accumulates and cannot be effectively diffused, which further causes the ventilation efficiency to decrease, resulting in the increase of the operating temperature of the voltage regulator, the accelerated aging of the insulation material, the decrease of the load capacity, and the increase of the energy consumption. Even the long-term overheating causes thermal stress damage to the metal parts or the misoperation of the protection system, which ultimately affects the stability and service life of the voltage regulator.

[0039] Embodiment 1, refer to Figure 1 Figure 8 For the first embodiment of the present application, an improved dry energy-saving voltage regulating device 102 is provided, which comprises a mounting base 101, and further comprises:

[0040] The collecting structure 200 comprises a receiving housing 201 fixed on the surface of the mounting base 101, a plurality of air guide holes 202 formed on the side of the receiving housing 201, an air inlet hole 203 formed on the side of the air guide hole 202, a groove 204 formed on the surface of the receiving housing 201, an air outlet hole 205 formed on the surface of the receiving housing 201 and located on the side of the groove 204, and a conduction assembly 206 fixed on the side of the air outlet hole 205 and located inside the receiving housing 201. The collecting structure 200 can effectively collect the air around the dry energy-saving voltage regulating device 102, provide sufficient air source for the subsequent air guiding and cooling process, and ensure the efficient operation of the entire ventilation system.

[0041] The air guiding structure 300 comprises a first partition shell 301 on the side of the conduction assembly 206, a second partition shell 302 fixed on the surface of the groove 204 and located inside the first partition shell 301, an air guiding cone 303 penetrating through the surfaces of the first partition shell 301 and the second partition shell 302, a multi-stage flow assembly 304 fixed on the surface of the second partition shell 302, and a lifting assembly 305 fixed on the multi-stage flow assembly 304. The air guiding structure 300 can effectively guide and distribute the collected air, form an orderly flow path around the voltage regulating device 102, enhance the ventilation effect, and prevent the backflow of cooled hot air.

[0042] ​The conduction assembly 206 comprises two support plates 2061 fixedly connected to the inside of the receiving shell 201 and located at symmetrical positions, two first rotating shafts 2062 rotatably connected to the surfaces of the two support plates 2061 and located at symmetrical positions, a rotating wheel 207 fixed to the top ends of the two first rotating shafts 2062, a transmission belt 2064 rotatably connected to the surface of the rotating wheel 207, and helical fan blades 2063 fixedly connected to the surface of the first rotating shaft 2062. The efficient conduction and flow control of the gas are realized, the helical fan blades 2063 can guide the gas to flow below the groove 204 and into the conical cylinder 3041, and the rotation of the first rotating shaft 2062 and the rotating wheel 207 provides power for the continuous flow of the gas, thereby improving the flow efficiency of the gas.

[0043] The surface of the rotating wheel 207 close to the top end of the support plate 2061 is fixedly connected with a second rotating shaft 2065, the surface of the second rotating shaft 2065 is fixedly connected with a circular gear 2066, the surface of the air guide hole 202 is fixedly connected with an electric fan 2069, and the surface of the first partition shell 301 is fixedly connected with a plurality of drainage cones 306. The electric fan 2069 can actively inhale air, and the rotation of the circular gear 2066 drives the pull rope 3042 to reciprocate up and down in the conical cylinder 3041, thereby realizing layer-by-layer compression and cooling of the gas and improving the cooling effect of the gas.

[0044] The air guide hole 202 adopts a design of outward expansion at both ends and inward contraction in the middle, and the cross-sectional shape of the inwardly-contracted middle part is rectangular. The air suction hole 203 is located at the midpoint of the inwardly-contracted middle part of the air guide hole 202. The air flow suction speed at the bottom of the dry energy-saving variable pressure regulator 102 can be increased, the gas collection efficiency can be improved, and a more sufficient gas source can be provided for subsequent gas treatment and ventilation process.

[0045] During use, the electric fan 2069 cooperates with the air guide hole 202 structure to provide power and efficiency guarantee for air collection. After the electric fan 2069 is powered on, the fan blades rotate at high speed, the suction force generated breaks the balance of the surrounding air, and actively drags the external air to the direction of the air guide hole 202, which is the initial power source for air entering the system.

[0046] The air guide hole 202 adopts a special design of outward expansion at both ends and inward contraction in the middle. When air enters the air guide hole 202 from the outwardly expanded port, the channel gradually narrows, and the air flow through each cross section of the air guide hole 202 needs to remain consistent in unit time. Therefore, the flow rate of the air passing through the inwardly-contracted middle part will be sharply accelerated. At the same time, the area with high flow rate has low pressure, so that a negative pressure area is formed in the inwardly-contracted part of the air guide hole 202, further enhancing the suction capacity of the external air. The suction force of the electric fan 2069 is superimposed, greatly accelerating the air flow suction speed at the bottom of the dry energy-saving variable pressure regulator 102.

[0047] After the air enters the receiving housing 201 through the air guide hole 202 and the air inlet hole 203 at the middle point, the conduction assembly 206 inside the receiving housing 201 completes the gas guiding work, two symmetrical support plates 2061 are stably installed in the receiving housing 201, providing a reliable support and rotation basis for the two first rotating shafts 2062, when the rotating wheel 207 at the top of the rotating shaft is connected and rotated by the transmission belt 2064, the mechanical connection enables the two rotating shafts to rotate synchronously, and the spiral fan blades 2063 fixed on the surface of the rotating shaft have a unique spiral shape and rotation mode, which can exert a spiral force on the air entering the receiving housing 201, and the air is accurately guided to the groove 204 below the surface of the receiving housing 201 under the action of the force, and then flows out through the air outlet hole 205, successfully completing the air collection process and providing sufficient and orderly air source for the subsequent ventilation process.

[0048] When the cooled and heated gas around the pressure regulating device 102 backflows, the pressure difference caused by the temperature difference drives the gas flow, the gas in the first partition housing 301 shrinks due to the low temperature, the pressure decreases, and the atmospheric pressure drives the gas around the pressure regulating device 102 to enter between the first partition housing 301 and the second partition housing 302 through the small hole of the flow guide cone 306, and finally enters the receiving housing 201 through the air outlet hole 205.

[0049] Embodiment 2, refer to Figure 1 Figure 11 For the second embodiment of the present application, the difference between this embodiment and the first embodiment is that the multi-stage flow assembly 304 includes a plurality of cone cylinders 3041 fixedly connected to the surface of the second partition housing 302 and arranged in a linear array, the adjacent cone cylinders 3041 are designed with a sealed structure, and the pull rope 3042 movably connected inside the cone cylinder 3041 has a diameter smaller than that of the taper hole of the cone cylinder 3041. The plurality of cone cylinders 3041 arranged in a linear array and sealed between adjacent ones can compress and cool the gas step by step, improving the cooling effect.

[0050] Further, compared with the embodiment, the surface of the pull rope 3042 is fixedly connected with the first top plate 3043, and the surface of the pull rope 3042 and the side of the first top plate 3043 are fixedly connected with the second top plate 3044, and the diameter of the second top plate 3044 is smaller than that of the first top plate 3043. The first top plate 3043 and the second top plate 3044 with a smaller diameter arranged on the pull rope 3042 can optimize the flow and compression process of the gas in the cone cylinder 3041, and enhance the exhaust efficiency.

[0051] ​Further, the top end of the pull rope 3042 is fixedly connected with a first connecting plate 2068 at the side of the first top plate 3043, the surface of the first connecting plate 2068 is fixedly connected with two axisymmetric tooth belts 2067, the tooth blocks of the tooth belts 2067 are opposite in opening direction, and the tooth belts 2067 are engagedly connected to the surface of the circular gear 2066. The design of the first connecting plate 2068 and the axisymmetric tooth belts 2067 at the top end of the pull rope 3042 realizes the same airflow flowing direction of the symmetrical spiral fan blades 2063 through the engagement of the tooth belts 2067 and the circular gear 2066.

[0052] In use, after the gas flows out from the groove 204, it enters the conical cylinder 3041 in the first partition shell 301. Since the pull rope 3042 is movably connected inside the conical cylinder 3041 of the multi-stage flow assembly 304, under the action of the connecting rod 3056, when the pull rope 3042 starts to reciprocate up and down in the conical cylinder 3041, the tooth belts 2067 fixed on the first connecting plate 2068 at the top end of the pull rope 3042 are in engagement with the circular gear 2066, and the up-and-down movement of the pull rope 3042 drives the tooth belts 2067 to produce linear motion. Since the tooth belts 2067 and the circular gear 2066 are engaged with each other, the linear motion of the tooth belts 2067 is converted into the rotational motion of the circular gear 2066. After the circular gear 2066 rotates, the rotating wheel 207 close to the top end of the supporting plate 2061 is driven to rotate through the second rotating shaft 2065, the rotating wheel 207 drives the two first rotating shafts 2062 to rotate synchronously through the transmission belt 2064, and then the rotational speed of the spiral fan blades 2063 installed on the surface of the first rotating shaft 2062 is increased. After the rotational speed of the spiral fan blades 2063 is increased, the guiding and pushing capacity of the spiral fan blades 2063 on air is enhanced, and external air can be more quickly sucked into the storage shell 201 through the air guiding hole 202 and the air suction hole 203, thereby greatly enhancing the air collection efficiency, forming a mutual promotion and efficient linkage circulation system between the collection structure 200 and the flow guide structure 300, and continuously providing support for the ventilation of the pressure regulating device 102.

[0053] The remaining structure is the same as that of example 1.

[0054] Example 3, refer to Figure 1 - Figure 14 This is the third embodiment of the present application, which is different from the second embodiment in that the lifting assembly 305 includes a second connecting plate 3058 fixedly connected to the top end of the pull rope 3042, a second connecting column 3057 fixedly connected to the surface of the second connecting plate 3058, and a connecting rod 3056 rotatably connected to the surface of the second connecting column 3057.

[0055] Compared with embodiment 2, further, the surface of the connecting rod 3056 is fixedly connected with the first connecting column 3055, the surface of the first connecting column 3055 is fixedly connected with the round plate 3054, and the first connecting column 3055 is located at the edge of the round plate 3054.

[0056] Further, the surface of the mounting base 101 is fixedly connected with the voltage regulator 102, the top end of the voltage regulator 102 is fixedly connected with the mounting top base 103, the surface of the mounting top base 103 is fixedly connected with the fixed base 3051, the surface of the fixed base 3051 is fixedly connected with the motor 3052, the surface of the motor 3052 is fixedly connected with the transmission shaft 3053, and the top end of the transmission shaft 3053 is fixedly connected with the round plate 3054.

[0057] In use, the motor 3052 at the top end of the voltage regulator 102 on the mounting base 101 is started, the rotating power of the motor 3052 is transmitted to the round plate 3054 through the transmission shaft 3053, so that the round plate 3054 starts to rotate continuously, and in the rotating process, the first connecting column 3055 at the edge changes position with the circumferential movement of the round plate 3054, which drives the connecting rod 3056 connected thereto to swing, and when the connecting rod 3056 swings, the force is transmitted to the first top plate 3043 and the second top plate 3044 fixedly connected to the surface of the pull rope 3042 through the second connecting column 3057, and with the up-and-down movement of the pull rope 3042, a piston-like movement effect is formed in the conical cylinder 3041, when the pull rope 3042 moves upward, the first top plate 3043 and the second top plate 3044 press the gas in the conical cylinder 3041 upward, so that the gas space becomes smaller and the pressure increases; when the pull rope 3042 moves downward, the gas is compressed again, and so on, so that the gas in the conical cylinder 3041 is compressed layer by layer, and the temperature of the compressed gas decreases, and then the low-temperature gas is discharged into the second partition shell 302, and since the flow guide cone 303 penetrates the surfaces of the first partition shell 301 and the second partition shell 302, the compressed low-temperature gas is blown to the surface of the voltage regulator 102 in a direction guided by the shape of the flow guide cone 303 under the action of pressure, so as to reduce the temperature of the gas around the voltage regulator 102 and realize targeted ventilation cooling of the voltage regulator 102.

[0058] The remaining structure is the same as that of embodiment 2.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting, and although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
