Description

Technical Field

[0001] The present invention belongs to the technical field of couplers, and particularly relates to a protective dual-channel signal coupler with a function of cooling and dehumidifying. Background Art

[0002] A coupler is a common power distribution component, which is an electro-optical-electrical conversion device that transmits electrical signals through light; it assembles a light-emitting source and a light-receiving device in the same sealed housing, and isolates them from each other with a transparent insulator; there are many types of optoelectronic couplers, and common ones include photodiode type, phototransistor type, photoresistor type, etc.; an optocoupler generally consists of three parts: light emission, light reception, and signal amplification, and its important indicators are coupling degree and insertion loss; it has good isolation effect on input and output electrical signals, the output signal has no influence on the input end, has strong anti-interference ability, stable operation, no contacts, long service life, and high transmission efficiency.

[0003] At present, for the signal coupler used in the existing 30 kV high-voltage line, during operation, since the conductors and components in the signal coupler have certain resistances, when current passes through these resistances, heat will be generated, which will cause a temperature difference inside and outside the signal coupler. When cold air from the outside enters the signal coupler and passes through the outer surface of the signal coupler, water vapor will adhere to the inner and outer surfaces of the signal coupler, resulting in the signal coupler being relatively humid, causing signal attenuation and reduction of the withstand voltage level of the signal coupler, and affecting the service life of the signal coupler. Based on this, a protective dual-channel signal coupler with a function of cooling and dehumidifying is proposed. Summary of the Invention

A blade is fixedly connected to the part of the outer surface of the reciprocating screw rod located in the heat exchange channel. The reciprocating screw rod penetrates through the heat exchange plate and is hermetically and rotatably connected with the heat exchange plate and extends out.

A limiting rod is fixedly connected to the heat exchange plate, and the limiting rod penetrates through the reciprocating frame and is slidably connected with the reciprocating frame.

[0015] The beneficial effects of the present invention are as follows: 1. By the combined use of the heat dissipation mechanism and the filtering component, when the coupler body is cooled, dust and moisture in the air can be removed, preventing the dust and moisture in the air from affecting the operation of the internal components of the coupler body, providing good protection for the coupler body. The operation of the heat dissipation mechanism can discharge the temperature generated when the internal components of the coupler body work, and blow it through the air blowing channels to both sides of the coupler body, blowing away the water vapor attached to both sides of the coupler body, realizing the dehumidification operation of the coupler body, preventing the coupler body from being relatively humid, resulting in signal attenuation and reduced withstand voltage level of the coupler body, providing good protection for the coupler body, ensuring the quality of signal transmission of the coupler body, and extending the service life of the coupler body.

[0016] 2. Through the setting of the dehumidification mechanism, the coolant in the heat exchange channel absorbs the temperature generated when the internal components of the coupler body work, conducts the temperature generated when the internal components of the coupler body work to the external environment, and cools the temperature absorbed by the coolant through the air circulation in the external environment. At the same time, the heat dissipation fins also conduct the temperature generated when the internal components of the coupler body work to the external environment, and also dissipate heat through the air circulation in the external environment, further improving the heat dissipation quality and efficiency of the coupler body.

[0017] 3. By the combined use of a heat dissipation mechanism, a dehumidification mechanism, and an extrusion mechanism, when the heat dissipation mechanism is working, the extrusion mechanism can be made to work, causing the extrusion mechanism to squeeze the hose inside the dehumidification mechanism, promoting the flow of the coolant inside the hose. As a result, the coolant inside the dehumidification mechanism can circulate, ensuring the water removal function of the dehumidification mechanism. And during this process, since the extrusion mechanism is arranged in a plate-like structure, the extrusion mechanism will stir and guide the hot air extracted by the heat dissipation mechanism to act on the hose, heating the coolant inside the hose and raising the temperature of the coolant inside the hose. This enables the coolant in the heat exchange channel to have a higher temperature, allowing the water vapor attached to the outer surfaces of the heat dissipation fins and the heat exchange plate to evaporate more quickly, improving the dehumidification efficiency. Moreover, the hose is located at the top of the air extraction chamber and at the top of the impeller, so the coolant inside the hose can absorb the temperature in the air extraction chamber, achieving the operation of cooling the temperature generated when the internal components of the coupler body work, further enhancing the heat dissipation efficiency of the internal components of the coupler body.

[0018] 4. By the combined use of a dehumidification mechanism and a swinging mechanism, when the coolant inside the dehumidification mechanism is in a flowing state, the flowing coolant inside the dehumidification mechanism will impact the blades, causing the blades to drive the reciprocating lead screw to rotate. Consequently, the reciprocating lead screw rotates, making the reciprocating frame slide back and forth along the outer surface of the reciprocating lead screw under the action of the limiting rod. Then, through the toothed rod, the gear is driven to rotate back and forth, causing the heat dissipation fins to swing back and forth. The water vapor and dust attached to the outer surface of the heat dissipation fins are thrown off under the action of the swinging force, further improving the dehumidification efficiency and promoting the flow efficiency of the gas through the heat dissipation fins and the heat dissipation fins, enhancing the heat dissipation quality.

Detailed implementation manners

[0021] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 andFigure 15 As shown in Figure 15 , a protective dual-channel signal coupler with a function of cooling and dehumidifying includes a mounting plate 1. The coupler body 2 is mounted on the top of the mounting plate 1 by bolts. The working principle of the coupler body 2 is that the medium-voltage broadband carrier bridge signal is accessed through the signal line to the signal interface, and is injected into the two-phase lines of the high-voltage line through the coupling signal processing unit and the dual-channel high-voltage processing module for signal transmission. A ceramic insulating terminal 3 is mounted on the top of the coupler body 2. Two partition plates 8 are fixedly connected inside the coupler body 2. There is a gap between the bottom of the partition plate 8 and the inner bottom of the coupler body 2 to facilitate the flow of air. Humidity sensors 11 are mounted on the adjacent sides of the two partition plates 8. It also includes: a heat dissipation mechanism 5 installed inside the coupler body 2. The heat dissipation mechanism 5 includes a motor 51 mounted on the top of the coupler body 2. A protective plate 4 is fixedly connected to the top of the coupler body 2. The motor 51 is located inside the protective plate 4. The output end of the motor 51 is fixedly connected to a rotating shaft 52. The rotating shaft 52 penetrates the top of the coupler body 2 and is rotatably connected to the coupler body 2. The bottom of the rotating shaft 52 is fixedly connected to an impeller 53. There is a notch on the top of the impeller 53. The inner top of the coupler body 2 is fixedly connected to an air extraction chamber 54. The outer surface of the impeller 53 does not fit against the inner surface of the air extraction chamber 54. Therefore, the hot air extracted by the impeller 53 can enter above the impeller 53. An air inlet hole 55 is opened at the bottom of the air extraction chamber 54. The outer surface of the air extraction chamber 54 is fixedly communicated with an exhaust pipe 56. The exhaust pipe 56 is fixedly connected to the inner surface of the coupler body 2. The exhaust end of the exhaust pipe 56 is fixedly communicated with a blowing channel 57; a filtering component 6 installed at both ends of the coupler body 2. The filtering component 6 includes an air inlet pipe 61 fixedly connected to both ends of the coupler body 2. An electric control valve is installed inside the air inlet pipe 61. The valve is in a closed state when heat dissipation and dehumidification are not required. An installation pipe 62 is hermetically installed inside the air inlet pipe 61. A filter screen 63 is fixedly connected to the air inlet end of the installation pipe 62. A dehumidification cage 64 is installed inside the installation pipe 62. A desiccant is filled inside the dehumidification cage 64.

[0023] During use, the humidity and temperature of the coupler body 2 are detected by the humidity and temperature sensor 11. When the humidity of the coupler body 2 reaches 60% and the internal-external temperature difference reaches 10 degrees, the electric control valve in the air inlet pipe 61 is opened at this time, and the motor 51 is started, so that the motor 51 drives the rotating shaft 52 to rotate, and then through the rotation of the impeller 53, the air extraction chamber 54 extracts the hot air flow in the environment where the internal components of the coupler body 2 are located below the impeller 53 through the air inlet hole 55. The outside air flows into the installation pipe 62 through the air inlet pipe 61, and after being filtered by the filter screen 63 and the moisture in the air is removed by the desiccant in the dehumidification cage 64, it can prevent water vapor from being generated in the coupler body 2. The dried air entering the coupler body 2, under the diversion of the partition plate 8, passes through the internal components of the coupler body 2, and after carrying the temperature generated when the internal components of the coupler body 2 work, enters the air extraction chamber 54 through the air inlet hole 55. The gas with temperature entering the air extraction chamber 54 will enter the exhaust pipe 56, and then be blown to both sides of the coupler body 2 through the air blowing channel 57, blowing away the water vapor attached to both sides of the coupler body 2, realizing the dehumidification operation of the coupler body 2, avoiding the coupler body 2 being relatively humid, resulting in signal attenuation and reduction of the withstand voltage level of the coupler body 2, providing good protection for the coupler body 2, ensuring the quality of signal transmission of the coupler body 2, and extending the service life of the coupler body 2.

[0024] Such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 12 , Figure 13 , Figure 14 and Figure 15As shown in the figure, the signal coupler further includes a dehumidifying mechanism 7 mounted on the coupler body 2. The dehumidifying mechanism 7 is provided in two groups, and the two groups of dehumidifying mechanisms 7 are connected by two hoses 72. The hoses 72 are fixedly connected inside the air extraction chamber 54 (it should be noted that the hoses 72 are only fixedly connected to the arc surface of the air extraction chamber 54), and are located at the top of the impeller 53. The dehumidifying mechanism 7 includes a heat exchange plate 74 fixedly connected to the coupler body 2. The top of the heat exchange plate 74 is inclined. The blowing end of the blowing channel 57 faces the inclined part of the heat exchange plate 74. A heat exchange channel 73 is provided inside the heat exchange plate 74. The liquid inlet end of the heat exchange channel 73 is fixedly communicated with a return pipe 71, and the liquid discharge end of the heat exchange channel 73 is fixedly communicated with a drain pipe 76. The return pipe 71 on one group of dehumidifying mechanisms 7 and the drain pipe 76 on the other group of dehumidifying mechanisms 7 are fixedly communicated by a hose 72. The return pipe 71 and the drain pipe 76 both penetrate through the air extraction chamber 54 and are fixedly connected to the air extraction chamber 54. The return pipe 71 and the drain pipe 76 both penetrate through the coupler body 2 and are fixedly connected to the coupler body 2. Heat dissipation fins 75 are fixedly connected to the heat exchange plate 74. The heat dissipation fins 75 penetrate through the side wall of the coupler body 2 and extend into the coupler body 2. The hoses 72, the return pipe 71, the drain pipe 76 and the heat exchange channel 73 are all filled with a coolant.

[0025] During use, the coolant in the heat exchange channel 73 absorbs the temperature generated when the internal components of the coupler body 2 work, conducts the temperature generated when the internal components of the coupler body 2 work to the external environment, and cools the temperature absorbed by the coolant through the air circulation in the external environment. At the same time, the heat dissipation fins 75 also conduct the temperature generated when the internal components of the coupler body 2 work to the external environment, and also dissipate heat through the air circulation in the external environment, further improving the heat dissipation quality and heat dissipation efficiency of the coupler body 2. And because the hose 72 is located at the top of the air extraction chamber 54 and at the top of the impeller 53, when the impeller 53 extracts hot air, the hot air will be gathered, resulting in an increase in the internal temperature of the air extraction chamber 54. Therefore, the coolant in the hose 72 will be heated. The hot air discharged from the blowing channel 57 will act on the heat exchange plate 74 and the heat dissipation fins 75 to remove impurities such as dust and water vapor attached to the heat exchange plate 74 and the heat dissipation fins 75, ensuring the heat exchange efficiency of the heat exchange plate 74 and the heat dissipation fins 75. The coolant in the hose 72 can absorb the temperature in the air extraction chamber 54, realizing the cooling operation of the temperature generated when the internal components of the coupler body 2 work inside the coupler body 2, and further improving the heat dissipation efficiency of the internal components of the coupler body 2.

[0026] Such as Figure 3 、 Figure 4 、 Figure 6 and Figure 13As shown in the figure, the signal coupler further includes a pressing mechanism 9 installed in the heat dissipation mechanism 5. The pressing mechanism 9 includes a fixing plate 91 fixedly connected to the outer surface of the rotating shaft 52. The fixing plate 91 is arranged in a vertically installed plate-like structure, and the length of the fixing plate 91 is greater than the radius of the impeller 53. A sliding frame 92 is slidably connected to the end of the fixing plate 91. A connecting spring 93 is fixedly connected to the end of the fixing plate 91. A fixing frame 94 is fixedly connected to the end of the sliding frame 92. A roller shaft 95 is rotatably connected inside the fixing frame 94. The connecting spring 93 is fixedly connected to the fixing frame 94. An air extraction chamber 54 is fixedly communicated with a communicating pipe 96 on the side wall at the top of the impeller 53. The communicating pipe 96 is fixedly communicated with an exhaust pipe 56.

[0027] During use, when the rotating shaft 52 rotates, it will drive the fixing plate 91 to rotate, and then drive the roller shaft 95 to do circular motion through the sliding frame 92 and the fixing frame 94. When the roller shaft 95 does circular motion, the roller shaft 95 will squeeze the hose 72 in one direction. When the roller shaft 95 squeezes the hose 72, the roller shaft 95 will push the sliding frame 92 to slide along the direction of the rotating shaft 52 inside the fixing plate 91, avoiding damage to the hose 72 due to excessive squeezing force. The heated coolant in the hose 72 will flow in the rotating direction of the roller shaft 95 under the squeezing action of the roller shaft 95, and then enter the drain pipe 76, and then enter the heat exchange channel 73 to replace the coolant in the heat exchange channel 73. The coolant with a lower temperature in the heat exchange channel 73 will flow back into the hose 72 through the return pipe 71. Since the hose 72 is located inside the coupler body 2, the coolant in the hose 72 can better absorb the temperature generated by the operation of the internal components of the coupler body 2, further improving the heat dissipation efficiency of the coupler body 2. When the coolant in the hose 72 absorbs the temperature generated by the operation of the internal components of the coupler body 2 and flows into the heat exchange channel 73, it will cause the heat exchange plate 74 to heat up, and the water vapor attached to the outer surface of the heat exchange plate 74 will evaporate under the action of the temperature, avoiding the water vapor from attaching to both sides of the coupler body 2, realizing the dehumidification operation of the coupler body 2, avoiding the coupler body 2 from being relatively humid, resulting in signal attenuation and reduction of the withstand voltage level of the coupler body 2, providing good protection for the coupler body 2, ensuring the quality of signal transmission of the coupler body 2, and extending the service life of the coupler body 2; At the same time, since the fixing plate 91 is arranged vertically, when the fixing plate 91 rotates, it will generate the effect of stirring the air. The gas extracted by the impeller 53 is drawn into the top of the impeller 53 through the notch at the top of the impeller 53, so that the hot air flows to and heats the coolant in the hose 72. The gas heated by the hose 72 will be discharged into the exhaust pipe 56 through the communicating pipe 96, and finally blown to the heat exchange plate 74 and the heat dissipation fins 75 through the blowing channel 57.

[0028] As Figure 1 、 Figure 2 、 Figure 5, Figure 8 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown in Figure 14 and Figure 15 , the signal coupler further includes a swing mechanism 10 rotatably connected to the end of the heat dissipation fins 75. The swing mechanism 10 includes a reciprocating lead screw 101 rotatably connected in the heat exchange channel 73. A blade 102 is fixedly connected to the portion of the outer surface of the reciprocating lead screw 101 located in the heat exchange channel 73. The reciprocating lead screw 101 passes through the heat exchange plate 74 and is rotatably connected to the heat exchange plate 74 in a sealed manner and extends out. A reciprocating frame 103 is threadedly connected to the portion of the reciprocating lead screw 101 extending out of the heat exchange plate 74. A toothed rod 104 is fixedly connected to the bottom of the reciprocating frame 103. A connecting shaft 106 is rotatably connected to the end of the heat dissipation fins 75. A heat dissipation fin 107 is fixedly connected to the outer surface of the connecting shaft 106. A gear 105 is fixedly connected to one end of the connecting shaft 106 extending out of the heat dissipation fins 75. The gear 105 meshes with the toothed rod 104. A limiting rod 108 is fixedly connected to the heat exchange plate 74. The limiting rod 108 passes through the reciprocating frame 103 and is slidably connected to the reciprocating frame 103.

[0029] When the coolant in the heat exchange channel 73 is in a flowing state, the flowing coolant will impact the blade 102, causing the blade 102 to drive the reciprocating lead screw 101 to rotate. As a result, the reciprocating frame 103 moves back and forth along the outer surface of the reciprocating lead screw 101 under the action of the limiting rod 108, further causing the toothed rod 104 to move back and forth. The back-and-forth movement of the toothed rod 104 will drive the gear 105 to rotate back and forth, further driving the connecting shaft 106 to rotate back and forth. The back-and-forth rotation of the connecting shaft 106 will drive the heat dissipation fin 107 to swing back and forth, and the water vapor and dust attached to the outer surface of the heat dissipation fin 107 will be shaken off under the action of the swinging force, further improving the dehumidification efficiency. Moreover, it can promote the circulation efficiency of the gas between the heat dissipation fin 107 and the heat dissipation fins 75, improve the heat dissipation quality, and can change the airflow direction of the hot gas blown out from the blowing channel 57 acting on the heat dissipation fin 107 and the heat dissipation fins 75, enabling the hot gas to better blow off the dust and water vapor on the heat dissipation fin 107 and the heat dissipation fins 75.

[0030] The specific working principle of the present invention is as follows: During use, the humidity and temperature of the coupler body 2 are detected by the temperature and humidity sensor 11. When the humidity of the coupler body 2 reaches 60% and the internal and external temperature difference reaches 10 degrees, the electric control valve in the intake pipe 61 is opened at this time, and the motor 51 is started, so that the motor 51 drives the rotating shaft 52 to rotate, and then the impeller 53 rotates, so that the air extraction chamber 54 extracts the hot air in the environment where the internal components of the coupler body 2 are located below the impeller 53 through the intake hole 55. The external air enters the installation pipe 62 through the intake pipe 61, and after passing through the filter screen 63 and removing dust and moisture in the air by the desiccant in the dehumidification cage 64, it enters the coupler body 2. Under the diversion of the partition plate 8, it passes through the internal components of the coupler body 2, carries the temperature generated when the internal components of the coupler body 2 work, and then enters the air extraction chamber 54 through the intake hole 55. The gas with temperature entering the air extraction chamber 54 will enter the exhaust pipe 56, and then be blown to both sides of the coupler body 2 through the blowing channel 57, blowing the water vapor attached to both sides of the coupler body 2 away from the coupler body 2, realizing the dehumidification operation of the coupler body 2, avoiding the coupler body 2 being relatively humid, resulting in signal attenuation and reduced withstand voltage level of the coupler body 2, providing good protection for the coupler body 2, ensuring the quality of signal transmission of the coupler body 2, and extending the service life of the coupler body 2; At the same time, since the flexible hose 72 is located at the top of the air extraction chamber 54 and at the top of the impeller 53, and when the impeller 53 extracts hot air, it will gather the hot air and cause the internal temperature of the air extraction chamber 54 to rise. Therefore, the coolant in the flexible hose 72 will be heated, and the hot air discharged from the blowing channel 57 will act on the heat exchange plate 74 and the heat dissipation fins 75, removing impurities such as dust and water vapor attached to the heat exchange plate 74 and the heat dissipation fins 75, ensuring the heat exchange efficiency of the heat exchange plate 74 and the heat dissipation fins 75. The coolant in the flexible hose 72 can absorb the temperature in the air extraction chamber 54, realizing the temperature reduction operation of the temperature generated when the internal components of the coupler body 2 work, and further improving the heat dissipation efficiency of the internal components of the coupler body 2; When the rotating shaft 52 rotates, it will drive the fixed plate 91 to rotate, and then drive the roller shaft 95 to do circular motion through the carriage 92 and the fixed frame 94. When the roller shaft 95 does circular motion, the roller shaft 95 will squeeze the hose 72 in one direction. When the roller shaft 95 squeezes the hose 72, the roller shaft 95 will push the carriage 92 to slide along the direction of the rotating shaft 52 in the fixed plate 91 through the fixed frame 94, avoiding damage to the hose 72 due to excessive extrusion force, so that the heated coolant in the hose 72 flows in the rotating direction of the roller shaft 95 under the extrusion of the roller shaft 95, and then enters the drain pipe 76, and then enters the heat exchange channel 73 to replace the coolant in the heat exchange channel 73, so that the coolant with a lower temperature in the heat exchange channel 73 flows back into the hose 72 through the return pipe 71. Since the hose 72 is located in the coupler body 2, the coolant in the hose 72 can better absorb the temperature generated by the operation of the internal components of the coupler body 2, further improving the heat dissipation efficiency of the coupler body 2. When the coolant in the hose 72 flows into the heat exchange channel 73 after absorbing the temperature generated by the operation of the internal components of the coupler body 2, it will cause the heat exchange plate 74 to heat up, and the water vapor attached to the outer surface of the heat exchange plate 74 will evaporate under the action of the temperature, avoiding the water vapor from attaching to both sides of the coupler body 2, realizing the dehumidification operation of the coupler body 2, avoiding the coupler body 2 from being relatively humid, resulting in signal attenuation and reduced withstand voltage level of the coupler body 2, providing good protection for the coupler body 2, ensuring the quality of signal transmission of the coupler body 2, and prolonging the service life of the coupler body 2; When the coolant is in a flowing state in the heat exchange channel 73, the flowing coolant will impact the blade 102, causing the blade 102 to drive the reciprocating lead screw 101 to rotate, and then causing the reciprocating frame 103 to move back and forth along the outer surface of the reciprocating lead screw 101 under the action of the limit rod 108, and then causing the toothed rod 104 to move back and forth. The back-and-forth movement of the toothed rod 104 will drive the gear 105 to rotate back and forth, and then drive the connecting shaft 106 to rotate back and forth. The back-and-forth rotation of the connecting shaft 106 will drive the heat sink 107 to swing back and forth, and the water vapor and dust attached to the outer surface of the heat sink 107 will be thrown off under the action of the swinging force, further improving the dehumidification efficiency, and promoting the flow efficiency of the gas between the heat sink 107 and the heat dissipation fins 75, improving the heat dissipation quality, and changing the air flow direction of the hot gas blown out from the blowing channel 57 acting on the heat sink 107 and the heat dissipation fins 75, so that the hot gas can better blow off the dust and water vapor on the heat sink 107 and the heat dissipation fins 75; Meanwhile, since the fixing plate 91 is arranged in a vertical form, when the fixing plate 91 rotates, it will generate the effect of agitating the air. The gas extracted by the impeller 53 is drawn into the top of the impeller 53 through the notch at the top of the impeller 53, so that the hot air flows to and heats the coolant in the hose 72. The gas heated by the hose 72 will be discharged into the exhaust pipe 56 through the connecting pipe 96, and finally blown to the heat exchange plate 74, the heat dissipation fins 75 and the heat sink 107 through the blowing channel 57, achieving the effect of intermittently accelerating the airflow blown out by the blowing channel 57. Furthermore, the acting force of the hot airflow blown out by the blowing channel 57 on the heat exchange plate 74, the heat dissipation fins 75 and the heat sink 107 is changed, so that the water vapor and dust attached to the heat exchange plate 74, the heat dissipation fins 75 and the heat sink 107 can be better blown off; After the temperature and humidity detected by the temperature and humidity sensor 11 decrease, the motor 51 and the electric control valve can be closed.
