Description

Technical Field

[0002] The large-diameter shielding ball structure is a device used to shield strong electromagnetic fields and dissipate heat to prevent the occurrence of corona phenomena. In the power system, strong electromagnetic fields and high temperatures are often generated at the busbar connections. Setting the large-diameter shielding ball structure at the busbar connections can protect the busbar copper sheet.

[0003] In the prior art, a coolant layer is provided in the shielding ball, and the busbar connection is sleeved in the middle of the shielding ball composed of two semicircular balls. When the busbar connection starts to transmit current, the coolant in the coolant layer absorbs the heat dissipated by the busbar through the thermal radiation of the shielding ball, and the coolant with a lower temperature in the circulation box is injected into the coolant layer through a water pump, so that the coolant with a high temperature in the coolant layer is transported to the circulation box, and the coolant is dissipated by the fan and the heat sink in the circulation box, thereby continuously cooling the busbar.

[0004] The existing large-diameter shielding ball structure still has some shortcomings in actual use. The heat sink is usually exposed to the external environment. After long-term use, due to the dust in the external environment, the dust will contact the surface of the heat sink with the flow of air.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figures 1 to 10 As shown, a large-diameter shielding ball structure of an embodiment of the present invention comprises a support plate 1, a shielding ball device 11 is fixedly arranged at the bottom of one end of the support plate 1, an L-shaped support plate 12 is fixedly connected to the bottom of the support plate 1, the L-shaped support plate 12 is composed of a vertical plate and a horizontal plate, the bottom end of the vertical plate is fixed to one end of the horizontal plate, a circulation box 13 is fixedly connected to the top of the horizontal plate, a radiator 14 is fixedly arranged on the circulation box 13, the radiator 14 is located on the side of the circulation box 13 away from the shielding ball device 11, and a shunt pipe 15 is fixedly arranged between the circulation box 13 and the shielding ball device 11;

[0042] A dust removal assembly is provided at the bottom of the support plate 1, and the dust removal assembly includes a scraper 213, and the dust attached to the surface of the radiator 14 is cleaned by moving the scraper 213;

[0043] A cleaning and collecting assembly is provided at the bottom of the support plate 1, and the cleaning and collecting assembly includes a collecting box 32. An upper cleaning plate 34 is fixedly provided below the support plate 1, and a lower cleaning plate 35 is fixedly provided below the upper cleaning plate 34. A clapping plate 315 is slidably provided below the support plate 1. After the scraper 213 cleans the dust on the radiator 14, the upper cleaning plate 34 and the lower cleaning plate 35 are used to clean the top and bottom of the scraper 213 respectively, and then the clapping plate 315 is used to clean the inside of the scraper 213, so that the dust on the scraper 213 is cleaned, and the cleaned dust is collected in the collecting box 32.

[0044] Specifically, the existing large-diameter shielding ball device 11 structure still has some shortcomings in actual use. The radiator 14 is usually exposed to the external environment. After long-term use, due to the dust in the external environment, the dust will contact the surface of the radiator 14 with the flow of air. Under the action of the electrostatic effect on the surface of the radiator 14, the dust will gradually adhere to and accumulate on the radiator 14, thereby reducing the heat dissipation effect of the radiator 14 and increasing the temperature of the coolant in the circulation box 13, thereby reducing the cooling effect of the shielding ball device 11 on the busbar, increasing the electric field strength of the busbar and its surrounding environment, and then causing corona discharge.

[0045] Therefore, the present invention solves this problem by setting a corresponding structure. When the busbar starts to transmit current, the water pump set in the circulation box 13 is started, and the coolant in the circulation box 13 is transported to the shielding ball device 11 through the shunt pipe 15 by the water pump, and the coolant in the shielding ball device 11 is transported to the circulation box 13. At this time, the temperature of the coolant in the circulation box 13 increases, and the coolant in the circulation box 13 contacts the radiator 14, and the heat is dissipated through the radiator 14;

[0046] During the heat dissipation process, the scraper 213 is driven to move at a fixed time, and the dust accumulated on the radiator 14 is cleaned by the movement of the scraper 213. After the scraper 213 cleans the dust, the upper cleaning plate 34 and the lower cleaning plate 35 clean the dust attached to the top and bottom surfaces of the scraper 213 as the scraper 213 moves. Then, the clapping plate 315 moves to slap the inside of the scraper 213, so that the dust in the scraper 213 is slapped out, thereby making the scraper 213 relatively clean, ensuring the effect of cleaning again.

[0047] The fan 16 blows air toward the radiator 14 , and the dust that is beaten down is collected by the collection box 32 under the action of gravity and the air blowing of the fan 16 . At the same time, the air blowing of the fan 16 also speeds up the heat dissipation of the radiator 14 , accelerating the cooling of the coolant in the circulation box 13 .

[0048] Embodiment 2

[0049] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0050] like Figures 2 to 7As shown, the dust removal assembly of this embodiment also includes a support plate 21, which is fixed to the bottom of the other side of the support plate 1, and a guide groove 22 is provided on one side of the support plate 21, and an electric telescopic rod 23 is fixedly connected to one end of the guide groove 22, and a slider 24 is slidably connected in the guide groove 22, and a resistance groove 25 is provided on one side of the slider 24, and a contact 26 is fixedly connected to the top of the resistance groove 25, and a contact 27 is fixedly connected to the bottom of the guide groove 22;

[0051] A guide groove 28 is provided on one side of the support plate 21, and a slider 29 is slidably connected in the guide groove 28. An electric telescopic rod 210 is fixedly connected to one end of the guide groove 28, and a displacement groove 211 is provided on one side of the slider 29; a guide rod 212 is slidably connected to one end of the slider 24, a scraper 213 is fixedly connected to the bottom end of the guide rod 212, one end of the scraper 213 is fixedly connected to a telescopic sleeve 214, a telescopic column 215 is slidably connected in the telescopic sleeve 214, a spring 216 is fixedly connected between the bottom end of the telescopic sleeve 214 and the telescopic column 215, and the telescopic column 215 slides in the displacement groove 211, the shape of the scraper 213 matches the shape of the radiator 14, and a cloth is laid on the contact surface between the scraper 213 and the radiator 14, the scraper 213 is moved horizontally by moving the slider 14, and the scraper 213 is moved up and down by moving the slider 29, so that the radiator 14 is dusted by the cloth.

[0052] Specifically, the heat sink 14 is composed of a plurality of heat sinks 14, and the displacement groove 211 is in the shape of a quadrilateral, consisting of two oblique grooves and two transverse grooves, and the depth of each oblique groove and transverse groove gradually deepens from one end to the other end, the shallowest part of the top transverse groove is connected to the top of the oblique groove on the left, the shallowest part of the left oblique groove is connected to the left end of the bottom transverse groove, the shallowest part of the bottom transverse groove is connected to the bottom end of the right transverse groove, and the shallowest part of the right oblique groove is connected to the right end of the top transverse groove;

[0053] Initially, if Figure 4 As shown, the electric telescopic rod 1 23 and the electric telescopic rod 210 are in a fully retracted state, the telescopic column 215 is located in the top transverse groove of the displacement groove 211, so that the scraper 213 is located at the top of the slider 29, and the spring 216 is not deformed. At this time, the scraper 213 does not contact the radiator 14, and the radiator 14 is on the movement trajectory of the scraper 213, as shown in FIG. Figure 5 As shown, contact one 26 conflicts with contact two 27 .

[0054] When dusting the radiator 14, the electric telescopic rod 23 is first started to extend the electric telescopic rod 23, and the slider 24 is driven to move through the output end of the electric telescopic rod 23, and then the scraper 213 is driven to move synchronously through the guide rod 212. During this process, the contact 26 and the contact 2 27 are no longer in conflict, and the telescopic column 215 is gradually retracted into the telescopic sleeve 214, and the spring 216 is elastically compressed until the electric telescopic rod 23 is extended to the farthest distance. At this time, the telescopic column 215 enters the top of the left inclined slot, and the spring 216 is elastically reset, so that the telescopic column 215 is reset. Under the limiting action of the left inclined slot, the scraper 213 will not move downward. At this time, the scraper 213 is located above the radiator 14, and the bottom of the scraper 213 wipes the dust on the top of the radiator 14 through the movement of the scraper 213;

[0055] Then, the electric telescopic rod 210 is started to extend until the electric telescopic rod 210 extends to the farthest distance. During this process, the telescopic column 215 on the scraper 213 is gradually displaced to the bottom end of the left inclined groove under the guidance of the left inclined groove and enters the bottom horizontal groove. Under the limiting action of the guide rod 212, the scraper 213 moves only vertically and linearly with the displacement of the telescopic column 215. At this time, the scraper 213 moves downward to remove dust on the vertical surface of the radiator 14.

[0056] When the telescopic column 215 enters the bottom horizontal groove, the top of the scraper 213 contacts the bottom of the radiator 14, and the scraper 213 cleans the bottom of the radiator 14 by contracting the electric telescopic rod 123 until the electric telescopic rod 123 is completely contracted, thereby completing the dust removal of the radiator 14;

[0057] The present invention drives the scraper 213 to clean the top of the radiator 14 by extending the electric telescopic rod 1 23, and then the electric telescopic rod 210 is extended, the telescopic column 215 is guided by the left inclined groove and the scraper 213 is limited by the guide rod 212, so that the scraper 213 only moves vertically downward, thereby cleaning the surface of the radiator 14. When the telescopic column 215 moves to the bottom end of the left inclined groove, it will enter the bottom horizontal groove, and the electric telescopic rod 1 23 will be contracted, so that the top of the scraper 213 cleans the dust on the bottom surface of the radiator 14, thereby completing the dust removal of the entire surface of the radiator 14, solving the problem that dust is not cleaned and gradually accumulates on the radiator 14, thereby reducing the heat dissipation effect of the radiator 14, improving the heat dissipation efficiency of the radiator 14, accelerating the cooling speed of the coolant, and improving the cooling effect of the shielding ball device 11 on the busbar, avoiding the shielding ball device 11. The cooling effect of the busbar on the busbar is reduced, which increases the electric field strength of the busbar and its surrounding environment, resulting in the occurrence of corona discharge phenomenon;

[0058] When the electric telescopic rod 1 23 is fully retracted, through the above operation, the telescopic column 215 enters the right inclined groove, and the scraper 213 only moves vertically upward through the contraction of the electric telescopic rod 210, until the telescopic column 215 moves to the top of the right inclined groove and enters the top horizontal groove, at which time the scraper 213 returns to the initial position to prepare for the next dust removal.

[0059] like Figures 2 to 4 As shown, the cleaning and collecting assembly of this embodiment consists of a cleaning component and a collecting component. The collecting component includes a card slot 31. The card slot 31 is opened at the bottom of one side of the support plate 21. The collecting box 32 slides in the card slot 31. The collecting box 32 is arranged below the fan 16.

[0060] Specifically, when the scraper 213 removes dust from the radiator 14, the scraper 213 blocks the air blowing of the fan 16, so that the dust removed from the radiator 14 falls into the collection box 32 under the action of gravity;

[0061] When the dust on the scraper 213 is cleaned, the cleaned dust falls into the collection box 32 under the action of gravity and the blowing of the fan 16, preventing the dust from falling into the equipment below.

[0062] like Figure 2 , Figure 3 and Figure 8 As shown, the cleaning component of this embodiment includes a fixed plate 33, which is fixed to the bottom of one side of the L-shaped support plate 12 and the circulation box 13, and an upper cleaning plate 34 and a lower cleaning plate 35 are respectively fixed on one side of the fixed plate 33. The upper cleaning plate 34 and the lower cleaning plate 35 are located on the movement trajectory of the scraper 213. When the scraper 213 passes between the upper cleaning plate 34 and the lower cleaning plate 35, one side of the upper cleaning plate 34 and the lower cleaning plate 35 respectively scrapes off the dust on the top and bottom of the scraper 213.

[0063] Specifically, the upper cleaning plate 34 and the lower cleaning plate 35 are set in a wedge shape, and the gap between the upper cleaning plate 34 and the lower cleaning plate 35 matches the size of the scraper 213;

[0064] During the retraction of the electric telescopic rod 23, the top and bottom of the scraper 213 respectively contact the wedge-shaped edges of the upper cleaning plate 34 and the lower cleaning plate 35, and the dust on the top and bottom of the scraper 213 is cleaned by the movement of the scraper 213.

[0065] like Figure 2 , Figure 3 and Figures 8 to 10As shown, the cleaning assembly of this embodiment also includes a support plate 36, which is fixed to the bottom of the support plate 1, and a fixed block 37 is fixedly connected to one side of the support plate 36, and a motor 38 is fixedly connected to the bottom of the fixed block 37, and a turntable rod 39 is rotatably connected to the other side of the support plate 36;

[0066] The turntable rod 39 is composed of a turntable and a turntable rod. A guide column 310 is fixedly connected to one side of the turntable. A limit block 311 is fixedly connected to the other side of the support plate 36. A reciprocating block 312 is slidably connected to the limit block 311. The reciprocating block 312 is composed of a straight groove plate and two limit slide bars. The two limit slide bars are set on both sides of the straight groove plate. One limit slide bar slides on the limit block 311, and the guide column 310 slides inside the straight groove plate.

[0067] A guide groove 313 is provided on the other side of the support plate 36, and a guide block 314 is interactively connected in the guide groove 313, and a clapper 315 is fixedly connected to one end of the guide block 314. The limit blocks 311 are symmetrically arranged, and the limit slide rods correspond to the limit blocks 311 one by one. The guide column 310 is eccentrically arranged, and one end of a limit slide rod is fixed to one end of the guide block 314;

[0068] Through the limiting effect of the limiting block 311, the guide block 314 only performs horizontal linear motion when the guide column 310 is displaced. When the contact 1 26 and the contact 2 27 collide with each other, the motor 38 is started to rotate the turntable rod 39, so that the guide block 314 drives the clapping plate 315 to reciprocate, and slaps the inside of the scraper 213 to slap out the dust inside.

[0069] Specifically, when contact 1 26 and contact 2 27 collide with each other, the driving motor 38 moves intermittently, and the output end of the motor 38 is fixed to the rotating rod constituting the turntable rod 39, so that the turntable rod 39 rotates, and then under the action of the limit block 311 and the limit reciprocating block 312, the reciprocating block 312 is driven to perform left and right linear reciprocating motion through the guide column 310, and then the clapper 315 is driven to perform left and right linear motion through the guide block 314. When the electric telescopic rod 210 contracts, the scraper 213 moves upward. During the upward movement of the scraper 213, the clapper 315 slaps the scraper 213 to clean the area of ​​the vertical surface of the radiator 14, and then removes the dust remaining thereon, so that most of the dust on the scraper 213 is cleaned out, thereby improving the dust removal effect of the scraper 213 on the radiator 14 when it is used again.

[0070] Working principle:

[0071] When the busbar starts to transmit current, the water pump provided in the circulation box 13 is started, and the coolant in the circulation box 13 is transported to the shielding ball device 11 through the shunt pipe 15 by the water pump, and the coolant in the shielding ball device 11 is transported to the circulation box 13. At this time, the temperature of the coolant in the circulation box 13 rises, and the coolant in the circulation box 13 contacts the radiator 14, and the heat is dissipated through the radiator 14. At the same time, the air blowing of the fan 16 also speeds up the heat dissipation of the radiator 14, so that the coolant in the circulation box 13 is cooled faster;

[0072] During the heat dissipation process of the radiator 14, the electric telescopic rod 1 23 and the electric telescopic rod 2 210 are started at a fixed time. The electric telescopic rod 1 23 is started first to extend it, and the slider 1 24 is driven to move through the output end of the electric telescopic rod 1 23, and then the scraper 213 is driven to move synchronously through the guide rod 212. During this process, the contact 1 26 and the contact 2 27 are no longer in conflict, and the telescopic column 215 is gradually retracted into the telescopic sleeve 214, and the spring 216 is elastically compressed until the electric telescopic rod 1 23 is extended to the farthest distance. At this time, the telescopic column 215 enters the top of the left inclined slot, and the spring 216 is elastically reset, so that the telescopic column 215 is reset. Under the limiting action of the left inclined slot, the scraper 213 will not move downward. At this time, the scraper 213 is located above the radiator 14, and the bottom of the scraper 213 wipes the dust on the top of the radiator 14 through the movement of the scraper 213;

[0073] Then, the electric telescopic rod 210 is started to extend until the electric telescopic rod 210 extends to the farthest distance. During this process, the telescopic column 215 on the scraper 213 is gradually displaced to the bottom end of the left inclined groove under the guidance of the left inclined groove and enters the bottom horizontal groove. Under the limiting action of the guide rod 212, the scraper 213 moves only vertically and linearly with the displacement of the telescopic column 215. At this time, the scraper 213 moves downward to remove dust on the vertical surface of the radiator 14.

[0074] When the telescopic column 215 enters the bottom horizontal groove, the top of the scraper 213 contacts the bottom of the radiator 14, and the scraper 213 cleans the bottom of the radiator 14 by contracting the electric telescopic rod 123 until the electric telescopic rod 123 is completely contracted, thereby completing the dust removal of the radiator 14;

[0075] During this process, the scraper 213 blocks the blowing of the fan 16, so that the dust cleaned from the radiator 14 falls into the collection box 32 under the action of gravity;

[0076] While the scraper 213 is cleaning the dust at the bottom of the radiator 14, the electric telescopic rod 123 continues to shrink, causing the scraper 213 to move synchronously, so that the top and bottom of the scraper 213 are respectively in contact with the wedge-shaped edges of the upper cleaning plate 34 and the lower cleaning plate 35, and the dust on the top and bottom of the scraper 213 is cleaned by the movement of the scraper 213.

[0077] When the electric telescopic rod 1 23 is fully retracted, the contact 1 26 and the contact 2 27 are in conflict with each other, and the motor 38 is driven to move intermittently. The output end of the motor 38 is fixed to the rotating rod constituting the turntable rod 39, so that the turntable rod 39 rotates, and then under the action of the limit block 311 and the limit reciprocating block 312, the reciprocating block 312 is driven to move back and forth in a straight line through the guide column 310, and then the clapper 315 is driven to move in a straight line in a straight line through the guide block 314;

[0078] At the same time, through the above operation, the telescopic column 215 enters the right inclined slot, and the scraper 213 only moves vertically upwards through the contraction of the electric telescopic rod 210. During the upward movement of the scraper 213, the clapper 315 claps the scraper 213 to clean the area of ​​the vertical surface of the radiator 14, thereby clapping and removing the dust remaining thereon, so that most of the dust on the scraper 213 is cleaned off, and the dust cleaned by the scraper 213 falls into the collection box 32 under the action of gravity and the blowing of the fan 16, preventing the dust from falling into the equipment below;

[0079] Until the telescopic column 215 moves to the top of the right inclined groove and enters the top transverse groove, the scraper 213 returns to the initial position to prepare for the next dust removal.

[0080] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
