Description

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 14 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, it includes a box 1 for storing a transformer, and threaded pipes 2 are fixedly connected to both sides of the box 1. The end of the threaded pipe 2 away from the box 1 is connected to an external pipe 3 through a nut; the external pipe 3 is a heat-conducting pipe.

[0037] A pipe-changing mechanism 4 for cooling water flow conversion, the pipe-changing mechanism 4 being arranged outside the box 1; A balancing mechanism 5 for automatically replenishing and discharging the cooling water in the tube is provided on the outside of the external tube 3; wherein the external tube 3 occupies three-quarters of the space outside the housing 1, so that the cooling water in the external tube 3 can exchange heat with the external environment for a long time.

[0038] The interior of the box body 1 is provided with a heat dissipation mechanism 6 and an adjustment mechanism 7; An intermediate tube 8 is fixedly connected to the center of the bottom of the external tube 3. A small motor 9 is connected to the interior of the intermediate tube 8 via a rod. The output end of the small motor 9 is connected to an impeller 10. The external tube 3 is securely connected to the threaded tube 2 via a nut. The other end of the threaded tube 2 is connected to the heat dissipation mechanism 6 via a diameter-converting tube 61. The other end of the heat dissipation mechanism 6 is connected to the tube-changing mechanism 4, and the connection between the two is similar to the connection between the external tube 3 and the threaded tube 2. Next, the small motor 9 inside the intermediate tube 8 is activated, causing the impeller 10 connected to its output end to rotate forward, causing the water to flow in the form of external tube 3-heat dissipation mechanism 6-tube-changing mechanism 4-external tube 3, cooling the transformer inside the housing 1.

[0039] The tube changing mechanism 4 includes a fixed tube 41, which is arranged outside the box 1. The bottom end of the fixed tube 41 is fixedly connected to a tube sleeve 42. The bottom of the inner cavity of the tube sleeve 42 is rotatably mounted with an arc tube 43, wherein the arc tube 43 can be deflected. The outer side of the arc tube 43 is connected to an elastic telescopic rod 44 through a sleeve, and the bottom end of the elastic telescopic rod 44 is fixedly connected to a chimeric ball 45; The bottom of the arc tube 43 is slidably fitted with an arc panel 46, and a circular hole 47 is opened on the top of the arc panel 46, wherein the circular hole 47 is fitted with the embedded ball 45; The top of the arc panel 46 is fixedly connected to a limiting block 48, wherein the outer side of the limiting block 48 is in contact with the chimeric ball 45 and limits the chimeric ball 45; wherein the arc tube 43 is first connected to the side tube 49, and the cooling water in the cooling system is filtered through the filter screen 402 in the side tube 49, and then the arc tube 43 is connected to the center tube 40.

[0040] The bottom of the curved panel 46 is fixedly connected to a discharge pipe 401, which discharges the cooling water inside the curved tube 43 and the external tube 3. The outer side of the curved tube 43 is connected to an elastic telescopic rod 44 through a sleeve, and the bottom end of the elastic telescopic rod 44 is fixedly connected to a chiseled ball 45. In addition, the bottom end of the curved tube 43 is slidably connected to the curved panel 46, and when the curved tube 43 slides along the top of the curved panel 46, no cooling water will flow out. At the same time, the top of the curved panel 46 is provided with three circular holes 47. Therefore, when the curved tube 43 moves to directly above the central tube 40, the chiseled ball 45 will chisele with the circular hole 47 at the center, thereby limiting the position of the curved tube 43. When the curved tube 43 rotates to directly above the side tube 49, the chiseled ball 45 will chisele with the circular hole 47 on the side tube 49 and be limited by the limit block 48.

[0041] The side tubes 49 and the center tube 40 are fixedly installed on the bottom of the arc panel 46, and the side tubes 49 are fixedly connected to the center tube 40. The bottom ends of the side tubes 49 and the center tube 40 are fixedly connected to the external tube 3; and when the arc tube 43 rotates to the top of the center tube 40, the water in the cooling system will circulate normally, thereby preventing the filter 402 in the pipeline from affecting the normal flow of water.

[0042] A filter 402 is fixedly connected to the interior of the side tube 49. The side tube 49 filters the cooling water, while the center tube 40 is used to circulate the cooling water. The curved tube 43 in the tube replacement mechanism 4 can rotate within the tube sleeve 42. In addition, the top of the tube sleeve 42 is connected to the fixed tube 41. Therefore, when the bottom end of the curved tube 43 rotates along the top of the curved plate 46 to directly above the discharge pipe 401, all water in the cooling system will be discharged from the discharge pipe 401. At the same time, water can be filled into the cold zone system through the discharge pipe 401. When the curved tube 43 rotates to directly above the side tube 49, water in the cooling system will enter the interior of the side tube 49. The filter 402 is fixedly connected to the interior of the side tube 49, thereby filtering the water entering the cooling system.

[0043] This design, in which the rotatable pipe is connected to different pipes below, has the following advantages: 1. When connected to a pipe with a filter 402, the fluid can be filtered to remove impurities; when connected to a drain pipe, it can be used to discharge wastewater or fill cooling water, conveniently achieving different fluid processing functions; when connected to a pipe without a filter 402, the fluid can flow normally without being affected by the filter 402. 2. If the central pipe 40 fails, the rotatable pipe can be connected to the side pipe 49 to continue system operation, improving the reliability and stability of the entire system and reducing production interruptions or other adverse effects caused by the failure.

[0044] like Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the balancing mechanism 5 includes a connecting tube 51, which is fixedly connected to the outside of the external tube 3. An extension column 52 is fixedly connected to the end of the connecting tube 51 away from the external tube 3. An end of the extension column 52 away from the connecting tube 51 is fixedly connected to a water bag 53, wherein the water bag 53 is tough. A conical groove 54 is provided inside the extension column 52, wherein the inner diameter of the center of the conical groove 54 is smaller than the size of the two ends. Elastic strips 55 are fixedly connected to the upper and lower sides of the central cavity of the conical groove 54. A flat-top ball 56 is fixedly connected to the end of the elastic strip 55 away from the conical groove 54. The flat-top ball 56 slides and fits inside the conical groove 54. When the temperature inside the box body 1 is too high, so that part of the cooling water enters the heat sink 65, the air pressure inside the external pipe 3 will be lower than the air pressure inside the water bag 53. At this time, the air pressure inside the extension pipe 3 will be lower than the air pressure inside the water bag 53. The flat-top ball 56 inside the column 52 will move to the right and stretch the elastic strip 55, and then the cooling water inside the water bag 53 will enter the external pipe 3 for replenishment. Similarly, when the temperature of the box 1 drops and returns to the initial temperature, the shape memory alloy spring 69 will return to its original state, causing the coolant in the heat sink 65 to be discharged back into the flow tube 63. At this time, the air pressure in the external pipe 3 will be greater than the air pressure in the water bag 53, causing the excess cooling water to be returned to the water bag 53, thereby filling and returning the cooling water.

[0045] The heat dissipation mechanism 6 includes a diameter-changing tube 61, which is fixedly connected to the inside of the threaded tube 2. The end of the diameter-changing tube 61 away from the threaded tube 2 is fixedly connected to a cooling tube 62. The outer side of the cooling tube 62 is fixedly connected to a flow-through tube 63. The outer end surface of the flow-through tube 63 and the interior of the cooling tube 62 are both fixedly connected to a diverter plate 64. The bottom of the flow-through pipe 63 is fixedly connected to a heat sink 65, and the bottom of the flow-through pipe 63 is appropriately fitted with a sealing plate 66. The bottom of the sealing plate 66 is fixedly connected to a protective cover 67. The bottom end of the protective cover 67 is fixedly connected to a pressure plate 68. The outer side of the pressure plate 68 is slidably fitted with the inner wall of the heat sink 65. The top of the pressure plate 68 is fixedly connected to a shape memory alloy spring 69, and the top of the shape memory alloy spring 69 is fixedly connected to the top of the inner cavity of the heat sink 65, wherein the protective cover 67 is used to prevent the cooling water from contacting the shape memory alloy spring 69. When the temperature inside the box 1 is too high and reaches a certain value, the shape memory alloy spring 69 will stretch and drive the pressure plate 68 fixedly connected to its bottom end to move downward, wherein the top of the pressure plate 68 is connected to the sealing plate 66 through the protective cover 67, so the sealing plate 66 will move downward and leave a gap. At this time, the cooling water flowing through the inside of the tube 63 will enter the space enclosed by the heat sink 65 and the top of the pressure plate 68 through the gap, thereby increasing the contact area between the overall cooling system and the heat inside the box 1, and increasing the heat dissipation effect. The diverter plate 64 plays the role of allowing part of the internal cooling water of the cooling tube 62 to enter the inside of the flow tube 63.

[0046] like Figure 13 and Figure 14As shown, the adjustment mechanism 7 includes a slider 71, which is slidably adapted to the outside of the box body 1. The end of the slider 71 away from the box body 1 is fixedly connected to a support rod 72, and the end of the support rod 72 away from the slider 71 is fixedly mounted with a motor 73. The output end of the motor 73 is connected to a gear 74, which is rotatably connected to the outside of the slider 71 via a rotating shaft. The outer side of the gear 74 is meshed with a rack 75, and the rack 75 is fixedly connected to the outside of the box body 1. The end of the slider 71 away from the support rod 72 is fixedly connected to a rack 76. Fans 77 are mounted on either side of the rack 76. A temperature sensor 78 is fixedly mounted on the end of the rack 76 away from the slider 71. When the temperature at a certain point in the transformer becomes too high, the temperature sensor 78 senses it and activates the motor 73, causing the gear 74 connected to its output end to mesh with the rack 75 and move the slider 71 upward. When the temperature reaches the point where the temperature is too high, the fan 77 activates and blows the excess heat away from the point toward the cooling system, thereby increasing the cooling effect.

[0047] When the present invention is in use: the external pipe 3 is fastened to the threaded pipe 2 by a nut, and the other end of the threaded pipe 2 is connected to the heat dissipation mechanism 6 through a diameter-changing pipe 61, and the other end of the heat dissipation mechanism 6 is connected to the pipe-changing mechanism 4, and the connection method of the two is the same as the connection method of the external pipe 3 and the threaded pipe 2. Then, the small motor 9 arranged inside the intermediate pipe 8 is started, so that the impeller 10 connected to its output end will rotate forward, causing the water to flow in the form of external pipe 3-heat dissipation mechanism 6-pipe-changing mechanism 4-external pipe 3 to dissipate heat for the transformer inside the box 1.

[0048] The arc tube 43 in the tube changing mechanism 4 can rotate in the tube sleeve 42. In addition, the top of the tube sleeve 42 is connected to the fixed tube 41. Therefore, when the bottom end of the arc tube 43 rotates along the top of the arc panel 46 to the top of the discharge pipe 401, the water in the cooling system will be discharged from the discharge pipe 401 to the outside. At the same time, the cold zone system can also be filled with water through the discharge pipe 401. When the arc tube 43 rotates to the top of the side tube 49, the water in the cooling system will enter the inside of the side tube 49, wherein the inside of the side tube 49 is fixedly connected with a filter screen 402. When the arc tube 43 rotates to the top of the center tube 40, the water in the cooling system will circulate normally.

[0049] The outer side of the arc tube 43 is connected to an elastic telescopic rod 44 through a sleeve, and the bottom end of the elastic telescopic rod 44 is fixedly connected to a chiseled ball 45. In addition, the bottom end of the arc tube 43 is slidably connected to the arc plate 46. When the arc tube 43 slides along the top of the arc plate 46, no cooling water flows out. At the same time, the top of the arc plate 46 has three circular holes 47. Therefore, when the arc tube 43 moves directly above the central tube 40, the chiseled ball 45 will chisele with the central circular hole 47, thereby limiting the position of the arc tube 43. When the arc tube 43 rotates to directly above the side tube 49, the chiseled ball 45 will chisele with the circular hole 47 in the side tube 49 and be limited by the limit block 48.

[0050] The arc tube 43 is first connected to the side tube 49 , the cooling water in the cooling system is filtered through the filter 402 in the side tube 49 , and then the arc tube 43 is connected to the central tube 40 .

[0051] When the temperature inside the box body 1 is too high and reaches a certain value, the shape memory alloy spring 69 will stretch and drive the pressure plate 68 fixedly connected to its bottom end to move downward, wherein the top of the pressure plate 68 is connected to the sealing plate 66 through the protective cover 67, so the sealing plate 66 will move downward and leave a gap. At this time, the cooling water flowing through the inside of the tube 63 will enter the space enclosed by the heat sink 65 and the top of the pressure plate 68 through the gap, thereby increasing the contact area between the overall cooling system and the heat inside the box body 1. When the temperature inside the box body 1 is too high, causing part of the cooling water to enter the heat sink 65, the air pressure inside the external tube 3 will be lower than the air pressure inside the water bag 53, and the flat-top ball 56 arranged inside the extension column 52 will move to the right and stretch the elastic strip 55, and then the cooling water inside the water bag 53 will enter the external tube 3 for replenishment. Similarly, when the temperature of the box body 1 drops and returns to its initial temperature, the shape memory alloy spring 69 will return to its original state, causing the coolant in the heat sink 65 to be discharged back into the flow tube 63. At this time, the air pressure in the external tube 3 will be higher than the air pressure in the water bag 53, causing the excess cooling water to be returned to the water bag 53.

[0052] When the temperature of a certain part of the transformer is too high, the temperature sensor 78 will be sensed and the motor 73 will be started, so that the gear 74 connected to its output end will engage with the rack 75 for transmission, and move upward with the slider 71 until it reaches the point where the temperature is too high. Then the fan 77 will start and blow the excess heat at that point toward the cooling system.

[0053] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
