Description

Technical Field

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

[0002] Computers are low-voltage products, which means that the operating voltage of their components is relatively low, generally within plus or minus 12 volts, and it is direct current. Ordinary AC power is 220 volts, which cannot be used directly on computer components. Therefore, computers, like many home appliances, need a power supply part, which is responsible for converting ordinary AC power into a voltage that can be used by the computer. It is generally installed inside the computer.

[0003] During use, the existing computer power supply is prone to voltage abnormalities due to poor contact at the connection and excessive temperature in the power supply installation area. When abnormal voltage occurs, the user's power socket is usually separated and disconnected from the computer connection plug to cut off the power to protect the computer power supply. However, in actual use, it is prone to the following defects: it is difficult to effectively deal with poor contact at the connection and excessive temperature in the installation area, resulting in frequent voltage abnormalities, and when the circuit is suddenly disconnected, an arc is easily generated between the connection plug and the socket, which is easy to cause thermal damage to the power supply and electromagnetic force, resulting in a reduction in its service life and poor subsequent use effects. Summary of the invention

[0004] Based on this, it is necessary to provide a computer power supply voltage abnormality protection device and method to address the problem of frequent voltage abnormalities and arcing between connecting plugs and sockets.

[0005] A computer power supply voltage anomaly protection device comprises a power supply body and a protective box installed to the outside thereof, the power supply body being respectively provided with a heat exhaust fan and a socket; a protection mechanism, the protection mechanism being arranged inside the protective box and being used to control the connection stability and quick disconnection between the socket and a docking plug; wherein the protection mechanism comprises an installation box docked with the socket, a sliding plate and a support plate, a group of round tubes being installed inside the support plate, a cavity being opened inside the installation box, the sliding plate being slidably connected to the inside of the cavity, an air duct being arranged inside the installation box and communicating with the cavity, the support plate being slidably connected to the inside of the installation box and its horizontal position being lower than the air duct.

[0006] In one embodiment, the protection mechanism further includes a transverse tube, an air guide groove and an exhaust groove are respectively provided on the inner wall of the protection box, the air guide groove is connected to the cavity through the transverse tube, and a group of through holes are provided inside the sliding plate.

[0007] In one of the embodiments, a mounting frame is provided on one side of the mounting box, a cross bar is installed between the mounting frame and the sliding plate, and a connection between the cross bar and the cavity is sealed.

[0008] In one embodiment, a strip groove is provided on the inner wall of the installation box, one end of the air duct extends into the interior of the strip groove, a semiconductor cooling plate is installed on the protective box, the cooling end of the semiconductor cooling plate is located between the protective box and the power supply body, and the heating end of the semiconductor cooling plate is located outside the protective box.

[0009] In one of the embodiments, magnets are embedded in opposite sides of the support plate and the sliding plate, and opposite sides of the two magnets are magnetically connected.

[0010] In one of the embodiments, an air collecting box aligned with the heat exhaust fan is installed on the outer side of the power supply body, a heat dissipation box is installed on the outer side of the power supply body, a discharge groove is opened on one side of the heat dissipation box, a folded pipe is installed between the heat dissipation box and the air collecting box, a three-way pipe is installed on the folded pipe, and both ends of the three-way pipe away from the folded pipe extend to the inside of the cavity and are respectively located on both sides of the sliding plate.

[0011] In one of the embodiments, a C-shaped cotton board is inserted into the interior of the installation frame, and an elastic fabric is installed inside the installation frame, and a cut is opened inside the elastic fabric.

[0012] In one of the embodiments, solenoid valves are installed at both ends of the three-way pipe close to the sliding plate and on the outer side of the air guide pipe.

[0013] In one of the embodiments, an intelligent digital voltmeter and a control panel electrically connected to the power supply body are respectively installed on the outer side of the protection box, and the heat exhaust fan and the intelligent digital voltmeter are electrically connected to the control panel.

[0014] The present invention also provides a computer power supply voltage abnormality protection method, the specific steps are as follows: S1. The installation frame is pre-connected with the computer connection plug. After the connection plug is placed in the installation box and connected 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 inside the socket; S2. When the gas is introduced into the cavity, part of the gas will be introduced into the gas guide groove along the through hole in the sliding plate, and then the gas can introduce the heat of the connection and the dust in the installation box into the exhaust groove, and the gas is discharged to the outside along the exhaust groove. During the discharge process, the C-shaped cotton plate is used to intercept the dust; S3. During the use of the power supply, if there is an abnormal voltage, the intelligent digital voltmeter will send the detection data to the control panel in time, and then the control panel will control the opening of the corresponding solenoid valve on the three-way pipe to introduce gas into the cavity and drive the installation frame to move, so that the connection plug is separated from the socket and the circuit is disconnected; S4. During the circuit disconnection operation, the control panel will open the solenoid valve on the air guide pipe, so that during the movement of the sliding plate, part of the gas is introduced into the interior of the strip groove along the through hole to discharge the disconnected circuit area, and the arc is extinguished and the temperature is reduced at the circuit disconnection point by air discharge; S5. During the sliding process of the sliding plate, the magnet between it and the support plate is magnetically connected, thereby driving the support plate to move until the support plate moves to collide with the inner wall of the strip groove, and then the two magnets are misaligned. At this time, the gas in the air duct will be discharged along the circular tube in a ring manner to the circuit disconnection point.

[0015] After the voltage abnormality occurs, the sliding plate can be driven by gas to move, so that it drives the installation frame to separate from the connecting plug and the socket to complete the power-off operation. In this process, the gas in the cavity can be sprayed along the strip groove to the power-off area to perform a preliminary arc extinguishing operation. Then, during the movement of the sliding plate, the round tube on the support plate follows the movement to move it into the strip groove. At this time, the gas discharge method is changed to annular spraying, and the arc is enveloped by annular gas to improve the cooling uniformity of the arc. When the air layer of the annular spray covers the arc, the electromagnetic radiation generated by the arc can be reduced. The propagation of the surrounding space reduces the electromagnetic interference to the internal components of the power supply 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 arc from re-breakdown, and reduce the heat damage and electromagnetic force of the arc to the power supply, thereby ensuring its service life and subsequent use effect. When the power supply is in use, the internal heat exhaust fan operates continuously, and the gas is cooled down in combination with semiconductor refrigeration. The gas is discharged along the gas guide groove, passes through the docking area of ​​the socket and the connecting plug, and is then discharged along the exhaust groove. When the dust blowing operation at the connection is completed, the heat in the connection area can be taken away, reducing the impact of high temperature on the power supply and the occurrence of voltage abnormalities.

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

[0024] Combine the following Figure 1-Figure 7 The computer power supply voltage abnormality protection device of the present invention is described.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, a computer power supply voltage abnormality protection device includes a power supply body 100 and a protective box 200 installed on the outside thereof, and a heat exhaust fan 110 and a socket are respectively provided on the power supply body 100; a protection mechanism 300, which is arranged inside the protective 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 connected to the cavity 311 is provided inside the installation box 310, and the support plate 330 is slidably connected to the inside of the installation box 310 and its horizontal position is lower than the air duct 312.

[0026] like Figure 3 and Figure 6 As shown, the protection mechanism 300 also includes a transverse tube 340 , the inner wall of the protection box 200 is respectively provided with an air guide groove 210 and an exhaust groove 220 , the air guide groove 210 is connected to the cavity 311 through the transverse tube 340 , and a group of through holes 321 are provided inside the sliding plate 320 .

[0027] After the socket and the connecting plug are connected, the gas discharged by the heat exhaust fan 110 can be introduced into the cavity 311. Figure 3 As shown, the gas is introduced along the left side of the sliding plate 320, and the sliding plate 320 is moved to the right area, so that it drives the connection plug and the socket to contact more closely, reducing the poor contact phenomenon. In this process, the through hole 321 is set, so that a small amount of gas in the cavity 311 can be introduced into the air guide groove 210 through the cross pipe 340, and it does not affect the pressure movement of the sliding plate 320 itself. Then, air is blown to the docking area between the socket and the connection plug, 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, so as to achieve the integrated cooling and dust removal operation effect. After the voltage abnormality occurs, the gas can enter the interior of the cavity 311 along the rear side of the sliding plate 320, and then the sliding plate 320 is driven to move to the left side, so that the connection plug and the socket are separated, and at this time, a small amount of gas in the cavity 311 is discharged along the air guide pipe 312. In the process of separating the connection plug and the socket, air is discharged from the connection to achieve arc extinguishing. During the movement of the sliding plate 320, the support plate 330 will also follow the movement until it moves to the bottom of the air duct 312, and then the circular tube 331 will be used to eject the gas in a ring shape, and the annular gas will be used to cover the arc to improve the cooling uniformity of the arc. When the annularly sprayed air layer covers the arc, it can reduce the propagation of electromagnetic radiation generated by the arc to the surrounding space, reduce electromagnetic interference to the internal components of the power supply body 100, and 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 arc from re-breakdown, and improve the arc extinguishing efficiency.

[0028] like Figure 3 and Figure 4 As shown, a mounting frame 313 is provided on one side of the mounting box 310, a cross bar is installed between the mounting frame 313 and the sliding plate 320, and the connection between the cross bar and the cavity 311 is sealed to ensure the air tightness in the cavity 311 and reduce gas leakage.

[0029] The installation frame 313 is connected to the connection plug. When the sliding plate 320 moves, the cross bar will drive the installation frame 313 and the connection plug to move accordingly.

[0030] like Figure 1 and Figure 5As shown, a strip groove 314 is provided on the inner wall of the installation box 310, one end of the air guide tube 312 extends to the inside of the strip groove 314, a semiconductor cooling plate is installed on the protective box 200, the cooling end of the semiconductor cooling plate is located between the protective box 200 and the power supply body 100, and the heating end of the semiconductor cooling plate is located on the outside of the protective box 200.

[0031] The gas discharged from the air duct 312 can be ejected toward the circuit disconnection area along the strip groove 314 to cool and eliminate the arc. The semiconductor cooling plate can be set to reduce the gas flow temperature in the protective box 200, thereby reducing the voltage abnormality caused by the power supply body 100 being affected by excessive temperature.

[0032] like Figure 5 As shown, magnets 350 are embedded on opposite sides of the support plate 330 and the sliding plate 320 , and opposite sides of the two magnets 350 are magnetically connected.

[0033] During the movement of the sliding plate 320 , the support plate 330 can follow the movement by utilizing the adsorption force between the two magnets 350 .

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As 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.

[0035] 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; 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.

[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 6As 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.

[0037] 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. 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.

[0038] 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 .

[0039] 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.

[0040] like Figure 1 As shown, an intelligent digital voltmeter and a control panel electrically connected to the power supply body 100 are respectively installed on the outer side of the protection box 200, and the heat exhaust fan 110 and the intelligent digital voltmeter are both electrically connected to the control panel.

[0041] The intelligent digital voltmeter is used to monitor the voltage condition in real time during the use of the power supply, and the control panel is used to control the corresponding equipment based on the signal sent by the intelligent digital voltmeter, which is more intelligent.

[0042] The present invention also provides a computer power supply voltage abnormality protection method, the specific steps are as follows: S1. The installation frame 313 is pre-connected with the computer connection plug. After the connection plug is placed in the installation box 310 and connected with the socket, the gas in the gas collecting 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 inside the socket, thereby 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 gas guide groove 210 along the through hole 321 in the sliding plate 320, and then the gas can introduce the heat of the connection and the dust in the installation box 310 into the exhaust groove 220, and the gas is discharged to the outside along the exhaust groove 220. During the discharge process, the C-shaped cotton plate 315 is used to intercept the dust; S3. During the use of the power source body 100, if an abnormal voltage occurs, the intelligent digital voltmeter will promptly send the detection data to the control panel, and then the control panel will control the opening of the corresponding solenoid valve 400 on the three-way pipe 360, so that the gas is introduced into the cavity 311 and the installation frame 313 moves, so that the connection plug is separated from the socket and the circuit is disconnected; 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 interior of the strip groove 314 along the through hole 321 to discharge the disconnected circuit area, and the arc extinguishing operation and temperature reduction treatment are performed on the disconnected circuit by air discharge; S5. During the sliding process of the sliding plate 320, the magnet 350 between it and the support plate 330 is magnetically connected, thereby driving the support plate 330 to move until the support plate 330 moves to collide with the inner wall of the strip groove 314, and then 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 a ring-shaped manner to the circuit disconnection point, and the annular gas is used to cover the arc to improve the uniformity of cooling the arc. When the annular sprayed air layer covers the arc, it can reduce the propagation of electromagnetic radiation generated by the arc to the surrounding space, reduce electromagnetic interference to the internal components of the power supply body 100, and 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 arc from re-breakdown.

[0043] Working principle: The installation frame 313 is pre-connected with the computer connection plug. After the connection plug is placed in the installation box 310 and connected with the socket, Figure 3As shown, the gas in the gas collecting box 120 is introduced into the cavity 311 along the end of the three-way pipe 360 ​​on the left side of the sliding plate 320, so that the sliding plate 320 drives the installation frame 313 and the connecting plug to move toward the inside of the socket, thereby ensuring the connection stability between the connecting plug and the socket and reducing the occurrence of poor contact. When the gas is introduced into the cavity 311, part of the gas will be introduced into the gas guide groove 210 along the through hole 321 in the sliding plate 320, and then the gas can introduce the heat of the connection and the dust in the installation box 310 into the exhaust groove 220, and the gas is discharged to the outside along the exhaust groove 220. The C-shaped cotton plate 31 is used in the discharge process. 5 to intercept dust. During the use of the power supply body 100, if there is an abnormal voltage phenomenon, the intelligent digital voltmeter will send the detection data to the control panel in time, and then the control panel will operate to open the corresponding solenoid valve 400 on the three-way pipe 360, so that the gas is introduced into the cavity 311 along the right end of the three-way pipe 360 ​​and drives the installation frame 313 to move, so that the connecting plug is separated from the socket and the circuit is disconnected. 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 interior of the strip groove 314 along the through hole 321, and the circuit disconnection area is The air discharge is carried out to extinguish the arc and cool down the disconnected part of the circuit by air discharge. During the sliding process of the sliding plate 320, the magnet 350 between the sliding plate 320 and the supporting plate 330 is magnetically connected, so that the supporting plate 330 can be driven to move until the supporting plate 330 moves to collide with the inner wall of the strip groove 314. Then, the two magnets 350 are displaced. At this time, the gas in the air guide tube 312 will be discharged to the disconnected part of the circuit in an annular manner along the circular tube 331. The annular gas is used to cover the arc to improve the uniformity of cooling the arc. When the air layer of the annular jet covers the arc, the propagation of the electromagnetic radiation generated by the arc to the surrounding space can be reduced. The electromagnetic interference to the internal components of the power supply body 100 is reduced. 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 arc from re-breakdown. The entire device can effectively cool down the installation area of ​​the power supply body 100 during use, and during the cooling process, it can assist the connection plug and the socket to dock stably. At the same time, when a voltage abnormality occurs, the power-off operation can be automatically performed, and during the power-off process, the generated arc can be processed in different ways to reduce the heat damage and electromagnetic force influence caused by the arc to the power supply, thereby ensuring its service life and subsequent use effect; The voltage anomaly is reduced by cooling, dust removal in the corresponding area and improving the stability of circuit connection. At the same time, the influence of voltage anomaly on the power supply body 100 is reduced by automatic disconnection of abnormality and arc elimination. It should be noted that the power supply body 100 in the present application can be used in conjunction with a voltage stabilizer, and the voltage abnormality protection operation can be used for normal protection processing when the voltage stabilizer fails or the voltage stabilization effect is poor; Furthermore, the pipe inside the support plate 330 can also replace the round pipe 331 with a conical pipe according to the connection conditions of power supplies of different specifications, so as to extend the arc length, increase its energy loss, and thus accelerate the extinction of the arc.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.
