Description

Technical Field

[0001] The present invention relates to the technical field of voltage abnormal protection, and particularly relates to a computer power supply voltage abnormal protection device and method. Background Art

[0002] Computers belong to weak-current products, that is, the operating voltage of components is relatively low, generally within plus or minus 12 volts and is direct current, while ordinary commercial power is 220 volts alternating current and cannot be directly used on computer components. Therefore, like many household appliances, a computer needs a power supply part to convert ordinary commercial power into a voltage that the computer can use, which is generally installed inside the computer. During the use of existing computer power supplies, voltage abnormalities are likely to occur due to poor contact at the connection or excessive temperature in the power supply installation area. When a voltage abnormality occurs, the user power socket and the computer connection plug are usually separated and disconnected for power-off operation to protect the computer power supply. However, in actual use, the following defects are likely to exist: it is not easy to effectively handle poor contact at the connection and excessive temperature in the installation area, resulting in frequent voltage abnormality phenomena. Moreover, when the circuit is suddenly disconnected, an electric arc is likely to be generated between the connection plug and the socket, which is likely to cause thermal damage and electromagnetic force influence on the power supply, reducing its service life and resulting in poor subsequent use effects. Summary of the Invention

[0003] Based on this, it is necessary to provide a computer power supply voltage abnormal protection device and method for the problems of frequent voltage abnormality phenomena and easy generation of electric arcs between the connection plug and the socket.

[0004] A computer power supply voltage abnormal protection device includes a power supply main body and a protective box installed on its outer side. A heat exhaust fan and a socket are respectively arranged on the power supply main body; a protection mechanism is arranged inside the protective box and is used to control the connection stability and quick disconnection between the socket and the docking plug. Among them, the protection mechanism includes an installation box docked with the socket, a sliding plate, and a support plate. A group of round tubes are installed inside the support plate. A cavity is formed inside the installation box. The sliding plate is slidably connected to the inside of the cavity. An air guide pipe communicating with the cavity is arranged inside the installation box. The support plate is slidably connected to the inside of the installation box and its horizontal position is lower than that of the air guide pipe. The protection mechanism further includes a horizontal pipe. Air guide grooves and exhaust grooves are respectively formed on the inner wall of the protective box. The air guide groove communicates with the cavity through the horizontal pipe. A group of through holes are formed inside the sliding plate. An installation frame is arranged on one side of the installation box. A cross bar is installed between the installation frame and the sliding plate. The connection between the cross bar and the cavity is sealed.

[0005] In one embodiment, a strip-shaped groove is formed in the inner wall of the installation box, one end of the air guide pipe extends into the strip-shaped groove, a semiconductor refrigerating sheet is installed on the protection box, the refrigerating end of the semiconductor refrigerating sheet is between the protection box and the power supply main body, and the heating end of the semiconductor refrigerating sheet is outside the protection box.

[0006] In one embodiment, magnets are embedded on the opposite sides of the support plate and the sliding plate, and the opposite sides of the two magnets are magnetically connected.

[0007] In one embodiment, a gas collecting box aligned with the exhaust fan is installed on the outside of the power supply main body, a heat dissipation box is installed on the outside of the power supply main body, a discharge groove is formed on one side of the heat dissipation box, a folding pipe is installed between the heat dissipation box and the gas collecting box, a three-way pipe is installed on the folding pipe, and both ends of the three-way pipe away from the folding pipe extend into the cavity and are respectively on both sides of the sliding plate.

[0008] In one embodiment, a C-shaped cotton board is inserted into the installation frame, an elastic cloth is installed inside the installation frame, and a cut is formed inside the elastic cloth.

[0009] In one embodiment, solenoid valves are installed on both ends of the three-way pipe close to the sliding plate and on the outside of the air guide pipe.

[0010] In one embodiment, an intelligent digital voltmeter and a control panel electrically connected to the power supply main body are installed on the outside of the protection box, and the exhaust fan and the intelligent digital voltmeter are both electrically connected to the control panel.

[0011] The present invention also provides a method for protecting the computer power supply voltage from abnormality, and the specific steps are as follows:

[0012] S1. The installation frame is pre-docked with the computer connection plug. After the connection plug is placed in the installation box and docked with the socket, the gas in the gas collecting box is introduced into the cavity along one end of the three-way pipe, so that the sliding plate drives the installation frame and the connection plug to move into the socket, ensuring the connection stability between the connection plug and the socket and reducing the occurrence of poor contact.

[0013] S2. When the gas is introduced into the cavity, part of the gas will be introduced into the air guide groove along the through hole in the sliding plate. Then, the gas can introduce the heat at the connection and the dust in the installation box into the exhaust groove together, and the gas is discharged to the outside along the exhaust groove. During the discharge process, the C-shaped cotton board is used to intercept the dust.

[0014] S3. During the use of the power supply main body, if a voltage anomaly occurs, the intelligent digital voltmeter will promptly send the detected data to the control panel. Subsequently, the control panel will operate to open the corresponding solenoid valve on the three-way pipe, allowing gas to be introduced into the cavity and driving the installation frame to move, separating the connection plug from the socket and disconnecting the circuit.

[0015] S4. During the circuit disconnection operation, the control panel will open the solenoid valve on the air duct. As the sliding plate moves, part of the gas will be introduced into the inside of the strip-shaped groove along the through hole, discharging the area where the circuit is disconnected, and using air discharge to perform arc extinguishing and cooling treatment on the circuit disconnection point.

[0016] S5. During the sliding process of the sliding plate, it is magnetically connected to the magnet on the support plate, which can drive the support plate to move until the support plate moves to contact the inner wall of the strip-shaped groove. Subsequently, the two magnets are misaligned. At this time, the gas in the air duct will be discharged in a circular manner along the circular pipe to the circuit disconnection point. Using the circular gas to shroud the arc can improve the uniformity of arc cooling. When the circularly ejected air layer shrouds the arc, it can reduce the propagation of electromagnetic radiation generated by the arc into the surrounding space, reduce the electromagnetic interference to the internal components of the power supply main body. At the same time, this method can prevent the arc from contacting the surrounding environment, reduce the damage of the arc to the insulation performance of the equipment, and prevent the re-breakdown of the arc.

[0017] After the voltage anomaly occurs, gas can be used to drive the sliding plate to move, causing it to drive the installation frame and separate the connection plug from the socket to complete the power-off operation. During this process, the gas in the cavity can be ejected along the strip-shaped groove to the power-off area for preliminary arc extinguishing. Then, during the movement of the sliding plate, the circular pipe on the support plate moves with it until it moves into the strip-shaped groove. At this time, the gas discharge method is changed to circular ejection. Using the circular gas to shroud the arc can improve the uniformity of arc cooling. When the circularly ejected air layer shrouds the arc, it can reduce the propagation of electromagnetic radiation generated by the arc into the surrounding space, reduce the electromagnetic interference to the internal components of the power supply main body. At the same time, this method can prevent the arc from contacting the surrounding environment, reduce the damage of the arc to the insulation performance of the equipment, prevent the re-breakdown of the arc, reduce the thermal damage and electromagnetic force impact on the power supply caused by the arc, and ensure its service life and subsequent use effect.

[0018] During the use of the power supply, the internal exhaust fan operates continuously, and the gas is cooled by semiconductor refrigeration. The gas is led out along the air guide groove, passes through the docking area of the socket and the connection plug, and is then discharged along the exhaust groove. When the dust blowing operation of the connection is completed, the heat of this connection area can be taken away, reducing the voltage anomaly phenomenon caused by the power supply being affected by high temperature.

The term "and / or" used in the specification of the present invention includes any and all combinations of one or more of the related listed items.

[0033] The following will describe the computer power supply voltage abnormal protection device of the present invention in conjunction with Figures 1-7 the following.

[0034] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in one embodiment, a computer power supply voltage abnormal protection device includes a power supply main body 100 and a protection box 200 installed on its outer side. A heat exhaust fan 110 and sockets are respectively arranged on the power supply main body 100; a protection mechanism 300, which is arranged inside the protection box 200 and is used to control the connection stability and quick disconnection between the socket and the docking plug; wherein, the protection mechanism 300 includes an installation box 310 docked with the socket, a sliding plate 320 and a support plate 330. A group of round tubes 331 are installed inside the support plate 330. A cavity 311 is opened inside the installation box 310. The sliding plate 320 is slidably connected to the inside of the cavity 311. An air duct 312 communicating with the cavity 311 is arranged inside the installation box 310. The support plate 330 is slidably connected to the inside of the installation box 310 and its horizontal position is lower than that of the air duct 312

[0035] As Figure 3 and Figure 6 shown, the protection mechanism 300 further includes a cross tube 340. Air guide grooves 210 and exhaust grooves 220 are respectively opened on the inner wall of the protection box 200. The air guide groove 210 communicates with the cavity 311 through the cross tube 340. A group of through holes 321 are opened inside the sliding plate 320.

[0036] After the socket and the connection plug are docked, the gas discharged by the heat exhaust fan 110 can be introduced into the cavity 311, as Figure 3 shown, so that the gas is introduced along the left side of the sliding plate 320, and the sliding plate 320 moves to the right area, making it drive the connection plug to contact the socket more tightly, reducing the phenomenon of poor contact. And in this process, with the setting of the through holes 321, a small amount of gas in the cavity 311 can be introduced into the air guide groove 210 through the cross tube 340, and it does not affect the pressure movement of the sliding plate 320 itself. Then, the docking area of the socket and the connection plug is blown, and the dust and heat at the circuit connection are taken away by the gas, and then discharged to the outside along the exhaust groove 220, achieving the integrated operation effect of cooling and dust removal. After the voltage abnormal phenomenon occurs, the gas can enter the inside of the cavity 311 along the rear side of the sliding plate 320, and then drive the sliding plate 320 to move to the left, separating the connection plug from the socket. And at this time, a small amount of gas in the cavity 311 is discharged along the air duct 312. During the separation process of the connection plug and the socket, air is discharged at their connection, achieving arc extinguishing treatment;

[0037] During the movement of the sliding plate 320, the support plate 330 will also move accordingly until it reaches directly below the air duct 312. Subsequently, the circular tube 331 is used to eject the discharged gas in a circular shape, covering the electric arc with the circular gas to improve the cooling uniformity of the electric arc. When the circularly sprayed air layer covers the electric arc, the electromagnetic radiation generated by the electric arc can be reduced from spreading into the surrounding space, reducing the electromagnetic interference to the internal components of the power supply main body 100. At the same time, this method can prevent the electric arc from contacting the surrounding environment, reducing the damage of the electric arc to the insulation performance of the equipment, preventing the re-breakdown of the electric arc, and improving the electric arc extinction efficiency.

[0038] As Figure 3 and Figure 4 shown, an installation frame 313 is provided on one side of the installation box 310. A cross bar is installed between the installation frame 313 and the sliding plate 320, and the connection between the cross bar and the cavity 311 is sealed to ensure the airtightness of the cavity 311 and reduce the phenomenon of gas leakage.

[0039] The installation frame 313 is docked with the connection plug. During the movement of the sliding plate 320, the cross bar will drive the installation frame 313 and the connection plug to move accordingly.

[0040] As Figure 1 and Figure 5 shown, a strip-shaped groove 314 is provided on the inner wall of the installation box 310. One end of the air duct 312 extends into the strip-shaped groove 314. A semiconductor refrigeration sheet is installed on the protection box 200. The refrigerating end of the semiconductor refrigeration sheet is located between the protection box 200 and the power supply main body 100, and the heating end of the semiconductor refrigeration sheet is located outside the protection box 200.

[0041] The gas discharged from the air duct 312 can be ejected along the strip-shaped groove 314 towards the circuit disconnection area to cool and eliminate the electric arc. By setting the semiconductor refrigeration sheet, the flowing temperature of the gas in the protection box 200 can be reduced, thereby reducing the phenomenon of abnormal voltage of the power supply main body 100 affected by excessive temperature.

[0042] As Figure 5 shown, magnets 350 are embedded on the opposite sides of the support plate 330 and the sliding plate 320, and the opposite sides of the two magnets 350 are magnetically connected.

[0043] During the movement of the sliding plate 320, the adsorption force between the two magnets 350 can be used to make the support plate 330 move accordingly.

[0044] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, an air collecting box 120 aligned with the heat exhaust fan 110 is installed on the outside of the power supply body 100, and a heat dissipation box 130 is installed on the outside of the power supply body 100. A discharge groove is opened on one side of the heat dissipation box 130. A folded pipe is installed between the heat dissipation box 130 and the air collecting box 120. A three-way pipe 360 is installed on the folded pipe. Both ends of the three-way pipe 360 away from the folded pipe extend to the inside of the cavity 311 and are respectively located on both sides of the sliding plate 320.

[0045] The gas collecting box 120 is used to centrally guide the gas discharged from the heat exhaust fan 110 into the heat dissipation box 130 along the folded pipe, and then the gas can be discharged from the discharge groove to between the power supply body 100 and the protection box 200, and the gas flows to take away the heat on the power supply body 100;

[0046] With the setting of the three-way pipe 360, part of the gas in the gas collecting box 120 can be introduced into the cavity 311, thereby driving the sliding plate 320 and the mounting frame 313 to move. Since the two ends of the three-way pipe 360 away from the folded tube are respectively located on both sides of the sliding plate 320, the sliding plate 320 can be moved in the corresponding direction by the gas discharged from the corresponding end, thereby performing bidirectional control on the sliding plate 320.

[0047] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a C-shaped cotton plate 315 is inserted into the interior of the installation frame 313, and an elastic cloth 316 is installed inside the installation frame 313. A cut is opened inside the elastic cloth 316, and two clamping bolts for resisting the connecting plug are installed on the installation frame 313. The clamping bolts can be used to assist the connection plug to dock with the installation frame 313.

[0048] After the connection plug is connected to the mounting frame 313, the connection plug will pass through the cutout and be covered by the elastic cloth 316 to achieve dust prevention. When the connection plug is not connected to the socket, the elastic cloth 316 can also cover the socket area to prevent dust.

[0049] By adopting the setting of the C-shaped cotton board 315, dust in the exhaust gas can be intercepted without affecting the gas exhaust operation. The user can regularly pull out the C-shaped cotton board 315 to clean the inside thereof.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, solenoid valves 400 are installed at both ends of the three-way pipe 360 close to the sliding plate 320 and on the outer side of the air guide pipe 312 .

[0051] By adopting the arrangement of the solenoid valve 400 , the opening and closing of the three-way pipe 360 and the air guide pipe 312 can be accurately controlled.

[0052] like Figure 1As shown, an intelligent digital voltmeter and a control panel, both electrically connected to the power supply main body 100, are respectively installed on the outer side of the protection box 200. The exhaust fan 110 and the intelligent digital voltmeter are both electrically connected to the control panel.

[0053] The intelligent digital voltmeter is used to monitor the voltage situation in real time during the use of the power supply, and the control panel is used to control the corresponding devices according to the signals sent by the intelligent digital voltmeter, making it more intelligent.

[0054] The present invention also provides a method for protecting the computer power supply voltage against anomalies, and the specific steps are as follows:

[0055] S1. First, the installation frame 313 is pre-docked with the computer connection plug. After the connection plug is placed into the installation box 310 and docked with the socket, the gas in the air collection box 120 is introduced into the cavity 311 along one end of the three-way pipe 360, so that the sliding plate 320 drives the installation frame 313 and the connection plug to move towards the inside of the socket, ensuring the connection stability between the connection plug and the socket and reducing the occurrence of poor contact.

[0056] S2. When the gas is introduced into the cavity 311, part of the gas will be introduced into the air guide groove 210 along the through hole 321 in the sliding plate 320. Subsequently, the gas can introduce the heat at the connection and the dust in the installation box 310 into the exhaust groove 220 together, and the gas is discharged to the outside along the exhaust groove 220. During the discharge process, the C-shaped cotton board 315 is used to intercept the dust.

[0057] S3. During the use of the power supply main body 100, if a voltage anomaly occurs, the intelligent digital voltmeter will promptly send the detected data to the control panel. Subsequently, the control panel controls and opens the corresponding solenoid valve 400 on the three-way pipe 360, so that the gas is introduced into the cavity 311 and drives the installation frame 313 to move, separating the connection plug from the socket and disconnecting the circuit.

[0058] S4. During the circuit disconnection operation, the control panel will open the solenoid valve 400 on the air guide pipe 312, so that during the movement of the sliding plate 320, part of the gas is introduced into the inside of the strip-shaped groove 314 along the through hole 321, discharging the area where the circuit is disconnected, and using the air discharge to perform arc extinguishing operation and cooling treatment on the circuit disconnection point.

[0059] S5. During the sliding process of the sliding plate 320, the magnet 350 between it and the support plate 330 is magnetically connected, so as to drive the movement of the support plate 330 until the support plate 330 moves to abut against the inner wall of the strip-shaped groove 314. Subsequently, the two magnets 350 are misaligned. At this time, the gas in the air duct 312 will be discharged along the circular tube 331 in an annular manner to the circuit break point, using the annular gas to cover the arc, improving the cooling uniformity of the arc. And when the annularly ejected air layer covers the arc, it can reduce the propagation of the electromagnetic radiation generated by the arc to the surrounding space, reduce the electromagnetic interference to the internal components of the power supply main body 100. At the same time, this method can prevent the arc from contacting the surrounding environment, reduce the damage of the arc to the insulation performance of the equipment, and prevent the re-breakdown of the arc.

[0060] Working principle: The mounting frame 313 is pre-connected to the computer connection plug. After the connection plug is placed in the mounting box 310 and docked with the socket, as Figure 3As shown in the figure, the gas in the air collecting box 120 is introduced into the cavity 311 along one end of the three-way pipe 360 on the left side of the sliding plate 320, so that the sliding plate 320 drives the mounting frame 313 and the connecting plug to move towards the inside of the socket, ensuring the connection stability between the connecting plug and the socket, reducing the occurrence of poor contact. When the gas is introduced into the cavity 311, part of the gas will be introduced into the air guide groove 210 along the through hole 321 in the sliding plate 320. Subsequently, the gas can introduce the heat at the connection and the dust in the mounting box 310 into the exhaust groove 220 together. The gas is discharged to the outside along the exhaust groove 220. During the discharge process, the C-shaped cotton board 315 is used to intercept the dust. During the use of the power supply main body 100, if there is an abnormal voltage phenomenon, the intelligent digital voltmeter will promptly send the detected data to the control panel. Subsequently, the control panel controls the solenoid valve 400 corresponding to the three-way pipe 360 to be opened, so that the gas is introduced into the cavity 311 along the right end of the three-way pipe 360 and drives the mounting frame 313 to move, separating the connecting plug from the socket and disconnecting the circuit. During the circuit disconnection operation, the control panel will open the solenoid valve 400 on the air guide pipe 312, so that during the movement of the sliding plate 320, part of the gas is introduced into the inside of the strip-shaped groove 314 along the through hole 321, discharging the disconnection area of the circuit. The air discharge is used to perform arc extinguishing operation and cooling treatment on the circuit disconnection point. During the sliding of the sliding plate 320, the magnet 350 between it and the support plate 330 is magnetically connected, so as to drive the support plate 330 to move until the support plate 330 moves to abut against the inner wall of the strip-shaped groove 314. Subsequently, the two magnets 350 are misaligned. At this time, the gas in the air guide pipe 312 will discharge the circuit disconnection point in a circular manner along the round pipe 331, covering the arc with the circular gas, improving the cooling uniformity of the arc. Moreover, when the circularly sprayed air layer covers the arc, it can reduce the propagation of the electromagnetic radiation generated by the arc to the surrounding space, reducing the electromagnetic interference to the internal components of the power supply main body 100. At the same time, this method can prevent the arc from contacting the surrounding environment, reducing the damage of the arc to the insulation performance of the equipment and preventing the re-breakdown of the arc. The entire device can effectively cool the installation area of the power supply main body 100 during its use. And during the cooling process, it can assist the docking stability between the connecting plug and the socket. At the same time, when there is an abnormal voltage, it can automatically perform a power-off operation. And during the power-off process, it can perform corresponding processing on the generated arc in different ways, reducing the thermal damage and electromagnetic force influence caused by the arc to the power supply, ensuring its service life and subsequent use effect;

[0061] Reduce the occurrence of abnormal voltage phenomena by means of cooling and temperature reduction, dust removal in the corresponding area, and improving the circuit connection stability. At the same time, adopt the dual methods of abnormal automatic disconnection and arc elimination to reduce the influence of abnormal voltage on the power supply main body 100;

[0062] It should be noted that the power supply main body 100 in this application can be used in combination with a voltage stabilizer, and this voltage abnormal protection operation can be normally protected and processed when the voltage stabilizer fails or the voltage stabilization effect is not good;

[0063] Moreover, the pipes in the support plate 330 can also replace the round pipe 331 with a tapered pipe according to the connection conditions of different specifications of the power supply, so as to extend the arc length, increase its energy loss, and thus accelerate the extinction of the arc.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0065] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

8. The computer power supply voltage abnormal protection method according to any one of claims 1-7, characterized in that, The specific steps are as follows: S1. First, use the mounting frame (313) to pre-dock with the computer connection plug. After the connection plug is placed in the mounting box (310) and docked with the socket, the gas in the air collecting box (120) is introduced into the cavity (311) along one end of the tee pipe (360), so that the sliding plate (320) drives the mounting frame (313) and the connection plug to move into the socket, ensuring the connection stability between the connection plug and the socket and reducing the occurrence of poor contact. S2. When the gas is introduced into the cavity (311), part of the gas will be introduced into the air guide groove (210) along the through hole (321) in the sliding plate (320). Then, the gas can introduce the heat at the connection and the dust in the mounting box (310) into the exhaust groove (220) together, and the gas is discharged to the outside along the exhaust groove (220). During the discharge process, the C-shaped cotton board (315) is used to intercept the dust. S3. During the use of the power supply main body (100), if a voltage abnormality occurs, the intelligent digital voltmeter will promptly send the detected data to the control panel. Subsequently, the control panel controls the solenoid valve (400) corresponding to the tee pipe (360) to be opened, so that the gas is introduced into the cavity (311) and drives the mounting frame (313) to move, separating the connection plug from the socket and disconnecting the circuit. S4. During the circuit disconnection operation, the control panel will open the solenoid valve (400) on the air duct (312). When the sliding plate (320) moves, part of the gas is introduced into the inside of the strip groove (314) along the through hole (321) to discharge the disconnected circuit area, and arc extinguishing operation and temperature reduction treatment are carried out on the circuit disconnection point by using air discharge. S5. During the sliding process of the sliding plate (320), it is magnetically connected to the magnet (350) between the sliding plate (320) and the support plate (330), so as to drive the support plate (330) to move until the support plate (330) moves to contact the inner wall of the strip groove (314). Subsequently, the two magnets (350) are misaligned. At this time, the gas in the air duct (312) will discharge the circuit disconnection point in a circular manner along the round pipe (331). The arc is shrouded by the circular gas to improve the cooling uniformity of the arc. When the circularly sprayed air layer shrouds the arc, the electromagnetic radiation generated by the arc can be reduced from spreading into the surrounding space, reducing the electromagnetic interference to the internal components of the power supply main body (100). At the same time, this method can prevent the arc from contacting the surrounding environment, reducing the damage of the arc to the insulation performance of the equipment and preventing the arc from re-breakdown.
