DETAILED DESCRIPTION

[0036] 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.

[0037] like Figures 1 to 7 As shown, a vacuum high-voltage circuit breaker described in the present invention includes a body assembly, a collecting mechanism, a gushing mechanism and a heat dissipation mechanism.

[0038] The body assembly includes a carrier case 1 and an insulating cylinder 14, wherein the insulating cylinder 14 is used to accommodate contacts and is arranged on the outer wall of the carrier case 1, wherein the carrier case 1 is provided with electronic components for constituting a vacuum high-voltage circuit breaker, wherein the moving contact and the static contact are arranged in the vacuum arc extinguishing chamber, and the vacuum arc extinguishing chamber is arranged at a position close to the insulating cylinder 14. In this embodiment, the insulating cylinder 14 is made of insulating ceramic material, and the insulating cylinder 14 is directly cooled when in use, thereby realizing rapid cooling of the vacuum arc extinguishing chamber.

[0039] The heat dissipation mechanism includes a heat exchange plate 13, a control motor 8 and a control fan blade 5. The heat exchange plate 13 is fixedly mounted on the outer wall of the insulating tube 14. The heat exchange plate 13 is made of common thermally conductive ceramic material and fits the outer wall of the insulating tube 14 to absorb the high temperature inside the insulating tube 14.

[0040] The control fan blade 5 is arranged on one side of the heat exchange plate 13, and the control fan blade 5 is fixedly installed on the output shaft of the control motor 8. The control fan blade 5 is driven by the control motor 8 to rotate, thereby generating airflow. The control fan blade 5 is driven by the control motor 8 to rotate and blow air toward the heat exchange plate 13, thereby increasing the air flow speed on the surface of the heat exchange plate 13, thereby improving the heat dissipation effect. Among them, the control motor 8 needs to be used outdoors, so a common waterproof motor is selected.

[0041] The collecting mechanism is used to collect rainwater. Since the entire device is arranged outdoors and the outdoor weather is changeable, the falling rainwater is collected by the collecting mechanism in rainy weather. Since the airflow flows to the heat exchange plate 13, floating dust is easily attached to the outer wall of the heat exchange plate 13. The collected and stored rainwater is used to flush the heat exchange plate 13, thereby maintaining the thermal conductivity of the heat exchange plate 13.

[0042] The gushing mechanism includes a storage cylinder 12, a control piston 19 and a valve shaft 22. The control piston 19 is slidably installed in the inner cavity of the storage cylinder 12. The outer wall of the control piston 19 is sealed and fitted with the inner wall of the storage cylinder 12. The control piston 19 slides back and forth to adjust the air pressure in the inner cavity of the storage cylinder 12.

[0043] After the storage cylinder 12 absorbs the rainwater collected by the collection mechanism, it controls the rainwater discharge by sliding the control piston 19, reduces the pressure in the inner cavity of the storage cylinder 12, sucks in the collected rainwater, and then increases the pressure in the inner cavity of the storage cylinder 12 to discharge the rainwater toward the heat exchange plate 13.

[0044] A drainage hole is provided on the outer wall of the valve shaft 22, and the valve shaft 22 is rotatably installed at the bottom of the storage cylinder 12 through a torsion spring, wherein a through hole for drainage is provided at the bottom of the storage cylinder 12, and the valve shaft 22 is perpendicular to the through hole. The valve shaft 22 is rotated to block the through hole on the bottom surface of the storage cylinder 12, thereby preventing water leakage and increasing the storage time of rainwater. When the heat exchange plate 13 needs to be cleaned, the valve shaft 22 is rotated until the drainage hole is connected to the through hole at the bottom of the storage cylinder 12. At this time, the piston 19 is controlled to slide to squeeze out the rainwater in the inner cavity of the storage cylinder 12, thereby flushing the outer wall of the heat exchange plate 13 and cleaning the dust.

[0045] The sliding of the control piston 19 and the rotation of the valve shaft 22 are both controlled by the control motor 8, wherein the control motor 8 can rotate forward and reverse. When the control motor 8 rotates forward, it only drives the control blades 5 to rotate, thereby reducing the load of the power output of the control motor 8 when blowing. When the control motor 8 reverses, it drives the control piston 19 to slide and the valve shaft 22 to rotate, thereby controlling the rainwater in the storage cylinder 12 to be discharged and flush the heat exchange plate 13.

[0046] As a preferred embodiment of the present invention, the collection mechanism includes an installation box 2, a fixing frame 3 and a filter layer 4. The installation box 2 is fixedly installed on the outer wall of the supporting chassis 1, and the storage cylinder 12 is fixedly installed on the inner wall of the installation box 2. The installation box 2 provides installation and support space for the storage cylinder 12.

[0047] The fixing frame 3 is fixedly installed in the inner cavity of the installation box 2, and the bottom of the fixing frame 3 is in contact with the outer wall of the storage tube 12. The fixing frame 3 is a funnel-shaped structure, and the filter layer 4 is fixedly installed on the inner wall of the fixing frame 3. The filter layer 4 is made of a common sponge material. In rainy weather, rainwater falls on the top of the fixing frame 3, is filtered by the filter layer 4, and is then sucked into the storage tube 12, which can reduce dust in the rainwater during use.

[0048] As a preferred embodiment of the present invention, a connecting pipe 11 is fixedly installed on the upper end of the storage cylinder 12 , the inner cavity of the connecting pipe 11 is connected to the inner cavity of the storage cylinder 12 , and rainwater filtered by the filter layer 4 enters the inner cavity of the storage cylinder 12 through the connecting pipe 11 .

[0049] A mounting frame 24 is fixedly mounted on the other end of the connecting pipe 11 , a guide rod 23 is slidably mounted on the inner wall of the mounting frame 24 , and the outer wall of the guide rod 23 is slidably fitted with the inner wall of the mounting frame 24 .

[0050] A sealing plug 28 is fixedly installed at the bottom of the guide rod 23. The sealing plug 28 is made of rubber. The sealing plug 28 is elastically connected to the inner wall of the connecting tube 11, and the sealing plug 28 is truncated. The inner wall of the connecting tube 11 is provided with a liquid inlet hole adapted to the sealing plug 28, thereby realizing a one-way conduction between the connecting tube 11 and the inside of the fixing frame 3, preventing rainwater inside the storage tube 12 from being discharged from the connecting tube 11 when the control piston 19 slides. At the same time, when the air pressure in the storage tube 12 is reduced, the sealing plug 28 is separated from the inner wall of the connecting tube 11 to facilitate the suction of rainwater.

[0051] As a preferred embodiment of the present invention, a support tube 25 is rotatably mounted on the outer wall of the storage tube 12 , and a transmission gear 16 is fixedly mounted on one axial end of the support tube 25 , so that the transmission gear 16 is rotatably connected to the side wall of the storage tube 12 through the support tube 25 .

[0052] The axis of the transmission gear 16 coincides with the axis of the valve shaft 22, and the rotation of the valve shaft 22 is controlled by the rotation of the transmission gear 16, and the rotation direction of the valve shaft 22 is controlled by the transmission gear 16, wherein the valve shaft 22 is affected by the elastic force of the torsion spring, and after the valve shaft 22 rotates, the elastic force of the torsion spring controls the valve shaft 22 to reset, so that the valve shaft 22 blocks the through hole at the bottom of the storage cylinder 12.

[0053] The axial end of the control piston 19 is fixedly mounted with a transmission shaft 7, one end of which extends to the outer wall of the mounting box 2 and is provided with a reciprocating thread, one end of which is located in the inner cavity of the storage tube 12, and the transmission shaft 7 located in the inner cavity of the storage tube 12 is a bare rod.

[0054] A connecting tube 6 is fixedly installed on the outer wall of the installation box 2, and a transmission sleeve 10 is rotatably installed on the other end of the connecting tube 6. The transmission sleeve 10 is connected to the transmission shaft 7 through a complex thread. The transmission sleeve 10 controls the reciprocating sliding of the transmission shaft 7 through a reciprocating thread, thereby driving the control piston 19 to slide reciprocatingly to facilitate the suction and discharge of rainwater.

[0055] A partition plate 21 is fixedly installed on the inner wall of the storage cylinder 12. Multiple partition plates 21 are evenly arranged along the inner wall of the storage cylinder 12. The partition plates 21 evenly divide the inner cavity of the storage cylinder 12 into multiple uniform chambers. A control piston 19 is arranged in each chamber. The multiple control pistons 19 are synchronously driven to slide by the transmission shaft 7. Each chamber corresponds to a through hole for drainage, so that water can be sprayed toward different positions of the heat exchange plate 13 during the reciprocating sliding of the control piston 19 to increase the flushing area.

[0056] A transmission rod 18 is fixedly mounted on one side of the transmission shaft 7 , and during the reciprocating sliding of the transmission shaft 7 , the transmission rod 18 is driven to slide synchronously.

[0057] One end of the transmission rod 18 extends to the inner cavity of the installation box 2 and is fixedly installed with a connecting plate 15. A transmission tooth plate 20 is fixedly installed on the side wall of the connecting plate 15. The transmission tooth plate 20 is flush with the transmission gear 16. The transmission rod 18 drives the transmission tooth plate 20 to slide through the connecting plate 15.

[0058] When the transmission shaft 7 drives the control piston 19 to slide, so that the inner cavity of the storage cylinder 12 is raised, the transmission tooth plate 20 gradually approaches the transmission gear 16 until the two are meshed, and the transmission gear 16 is controlled to rotate by the transmission tooth plate 20, thereby driving the valve shaft 22 to rotate, so as to facilitate the discharge of rainwater.

[0059] When the transmission shaft 7 drives the control piston 19 to slide and the inner cavity of the storage cylinder 12 is lowered, the transmission tooth plate 20 slides in the opposite direction and cooperates with the elastic force of the torsion spring to control the valve shaft 22 to block the through hole at the bottom of the storage cylinder 12, so that the inner cavity of the storage cylinder 12 can absorb rainwater until the transmission tooth plate 20 and the transmission gear 16 are separated. At this time, the torsion spring controls the valve shaft 22 to reset for the next operation.

[0060] As a preferred embodiment of the present invention, a transmission bevel gear 26 is fixedly mounted on one axial end of the valve shaft 22 . A plurality of transmission bevel gears 26 are arranged in a ring shape along the axial direction of the valve shaft 22 . The outer wall of the transmission bevel gear 26 is inclined.

[0061] A transmission plate 27 is fixedly installed on the axial end of the transmission gear 16. The transmission plate 27 is tilted and has an elastic structure. One end of the transmission plate 27 is in real-time contact with the outer wall of the transmission bevel gear 26. The positive rotation of the transmission gear 16 drives the valve shaft 22 to rotate by pressing the transmission bevel gear 26 with the transmission plate 27. The reverse rotation of the transmission gear 16 controls the valve shaft 22 to reset through the elastic force of the torsion spring, thereby realizing the control of the rotation of the valve shaft 22 through the sliding direction of the transmission tooth plate 20.

[0062] A mounting cover 9 is fixedly mounted on the side wall of the mounting box 2 , and the control motor 8 is fixedly mounted inside the mounting cover 9 . The mounting cover 9 provides mounting and support for the control motor 8 .

[0063] A transmission disc 17 is sleeved on the outer wall of the output shaft of the control motor 8 . The rotation of the transmission disc 17 is controlled by the control motor 8 . The transmission disc 17 is rotatably arranged inside the mounting cover 9 through a bracket.

[0064] The axis of the transmission disc 17 is parallel to the axial direction of the transmission shaft 7. The transmission sleeve 10 is connected to the transmission disc 17 through a transmission belt. The rotation of the transmission disc 17 drives the transmission sleeve 10 to rotate through the transmission belt, thereby controlling the reciprocating sliding of the transmission shaft 7 and the transmission rod 18 to achieve cleaning of the heat exchange plate 13.

[0065] A control bevel block 29 is fixedly installed on the inner wall of the transmission disk 17, and the outer wall of the control bevel block 29 is inclined. A plurality of control bevel blocks 29 are evenly arranged in a ring shape along the axis of the output shaft of the control motor 8. An elastic sheet 30 for pushing the control bevel block 29 is fixedly installed on the output shaft of the control motor 8. When the output shaft of the control motor 8 rotates, the elastic sheet 30 is driven to rotate.

[0066] When the output shaft of the control motor 8 rotates in the forward direction, the elastic sheet 30 and the control bevel block 29 slip, and the transmission disk 17 remains stationary. When the output shaft of the control motor 8 rotates in the reverse direction, the elastic sheet 30 pushes the control bevel block 29 to drive the transmission disk 17 to rotate, and then drives the transmission sleeve 10 to rotate, and controls the transmission shaft 7 and the transmission rod 18 to slide back and forth, so as to clean the heat exchange plate 13.
