[0002] As DC power supply cables are stable and convenient to lay out, interfaces are simple, communication equipment failure rates are low, and maintenance workload is small, it can achieve high reliability, low latency, and long-distance data transmission. DC power line carrier technology is gradually being used in smart buildings, smart parks, and flexible load power supply. With the DC access of distributed photovoltaic, energy storage and other resources, the power grid dispatching center can effectively increase the utilization rate of distributed resources, improve the proportion of new energy consumption capacity, and support the safe and stable operation of the power system through the DC power line carrier to control distributed energy.

[0003] The power line carrier communication system refers to a power communication system that uses the transmission line as the transmission medium for the carrier signal. The AC power currently used has two frequencies, 50HZ and 60HZ. The power line will have two peaks in each AC cycle, bringing two pulse interferences, that is, there is a fixed 100HZ or 120HZ pulse interference on the power line, and the interference time is about 2ms. Power line carrier communication is a unique and basic communication method for power systems. It refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carriers.

[0006] 2. When using the anti-interference device, the heat is generally dissipated through the ventilation holes. However, the presence of ventilation holes can easily weaken its anti-interference ability, causing it to lose its corresponding anti-interference ability.

[0007] 3. When connecting the cable to the anti-interference device, the connection between the cable and the anti-interference device is prone to bending over a long period of time, causing the cable to break, affecting the stability of the connection between the cable and the anti-interference device.

The cold air passes through the first ventilation hole to dissipate heat and cool down the bottom of the signal anti-interference device, and the cold air also passes through the third ventilation hole to the plug-in position of the cable and the port of the signal anti-interference device. Since the third ventilation hole is narrow at the top and wide at the bottom, and the cross-sectional area changes from large to small, the flow rate of the cold air passing through the third ventilation hole is increased, and the plug-in position of the cable and the port of the signal anti-interference device can be effectively cooled, and the cold air flows upward through the second ventilation hole. At this time, the hot air in the signal anti-interference device just overflows to the outside through the heat dissipation holes on both sides of the signal anti-interference device, and then the cold air can accelerate the dissipation of the hot air, further increasing the heat dissipation effect of the signal anti-interference device.

The outer wall of the grounding guide rod is sleeved with a tension spring fixedly connected to the top of the fixed plate, and the top end of the tension spring is fixedly connected to the bottom of the mounting plate; when the extrusion plate generates a downward extrusion force on the signal anti-interference device through the second inclined surface, the signal anti-interference device squeezes the grounding guide rod downward, and the grounding guide rod is just grounded, thereby increasing the anti-interference ability of the signal anti-interference device.

[0020] In a possible design, the top and bottom of the extrusion plate on one side close to the signal anti-interference device are both provided with a first inclined surface, and the outer wall of the signal anti-interference device is fixedly connected to two annular frames arranged up and down, and the top and bottom of the annular frames are both provided with a second inclined surface, and the first inclined surface cooperates with the second inclined surface; when the signal anti-interference device is placed in the placement groove from top to bottom, the extrusion plate can be pushed outward and extended into the sleeve through the cooperation of the second inclined surface and the first inclined surface, and when the extrusion plate moves toward the direction of the signal anti-interference device under the action of the sleeve and the second spring, the extrusion plate can not only generate downward pressure on the signal anti-interference device, but also generate an extrusion force toward the middle of the signal anti-interference device through the cooperation of the first inclined surface and the second inclined surface, so that the fixation of the signal anti-interference device is quite stable.

[0021] In a possible design, two fixing plates are welded on both sides of the top of the mounting plate, and screws are threaded through the two fixing plates. The ends of the two screws that are close to each other are rotatably connected to the sides of the two I-shaped bottom plates that are away from each other. The rotation of the screws drives the lower bottom plate and the upper bottom plate to move toward the direction of the signal anti-interference device, so that the cable can be tightly connected to the port of the signal anti-interference device to avoid loosening of the connection between the cable and the port of the signal anti-interference device.

[0022] In a possible design, two base plates are welded on both sides of the top of the mounting plate, the two base plates on the same side are rotatably connected with a same rotating shaft, a U-shaped shielding plate is fixed to the outer wall of the rotating shaft, two torsion springs are sleeved on the outer wall of the rotating shaft, the ends of the two torsion springs close to each other are respectively fixedly connected to the two sides of the U-shaped shielding plate, and the ends of the two torsion springs away from each other are respectively fixedly connected to the two base plates, the side of the U-shaped shielding plate close to the signal anti-interference device is fixed with an arc-shaped air guide plate by bolts, and the U-shaped shielding plate, the arc-shaped air guide plate and the second ventilation hole are connected. Cooperation; under the action of the torsion spring, the two U-shaped shielding plates rotate toward the middle, and the two U-shaped shielding plates can just block the heat dissipation holes on both sides of the signal anti-interference device, to prevent the interference signal from interfering with the inside of the signal anti-interference device through the heat dissipation holes. In addition, the cold air moving upward through the second ventilation hole can be blown to the top of the signal anti-interference device through the guidance of the arc-shaped air guide plate, which not only dissipates heat and cools the top of the signal anti-interference device, but also can blow away the dust on the top of the signal anti-interference device, to prevent dust from accumulating on the top of the signal anti-interference device and hindering the normal heat dissipation of the signal anti-interference device.

[0023] In this application, a method for using a DC power line carrier anti-interference device for distributed energy control includes the following steps:

[0024] S1. Move the two U-shaped shielding plates to both sides, place the signal anti-interference device in the placement slot, and use the pull belt to drive the upper bottom plate to move up. The external cables pass through the upper bottom plate and the lower bottom plate and plug into the port of the signal anti-interference device. Release the pull on the upper bottom plate, and the upper bottom plate moves down under the elastic force of the first spring. At this time, the lower bottom plate and the upper bottom plate complete the clamping of the cable, and the central axis of the cable coincides with the axis of the port of the signal anti-interference device, so that the cable can always be kept level with the port of the signal anti-interference device, avoiding the bending of the cable in the later stage;

[0025] S2. In addition, when the upper base plate moves up, the fixing frame is driven to move up, and the fixing frame drives the extrusion plate and the sleeve to move in the direction of the signal anti-interference device through the connecting rod, and the placement slot is initially clamped by the cooperation of the second spring and the extrusion plate. Due to the cooperation of the first inclined surface and the second inclined surface, the extrusion plate can not only generate downward pressure on the signal anti-interference device, but also generate an extrusion force toward the middle of the signal anti-interference device, so that the fixation of the signal anti-interference device is quite stable. When the upper base plate moves down and resets, the sleeve resets a certain distance under the action of the connecting rod, and the elastic force of the second spring can still push the extrusion plate to pressurize and fix the signal anti-interference device, so that the fixation of the signal anti-interference device can be easily completed, and the installation and disassembly are extremely convenient. When the extrusion plate generates a downward extrusion force on the signal anti-interference device through the second inclined surface, the signal anti-interference device squeezes the grounding guide rod downward, and the grounding guide rod is just grounded, thereby increasing the anti-interference ability of the signal anti-interference device;

[0026] S3. When ventilation and heat dissipation are required, start the ventilation fan, which blows cold air from bottom to top. The cold air dissipates heat and cools the bottom of the signal anti-interference device through the first ventilation hole, and the cold air also blows to the plug-in position of the cable and the port of the signal anti-interference device through the third ventilation hole. Since the third ventilation hole is narrow at the top and wide at the bottom, and the cross-sectional area changes from large to small, the flow rate of the cold air through the third ventilation hole increases, and the plug-in position of the cable and the port of the signal anti-interference device can be effectively cooled, and the cold air flows upward through the second ventilation hole. At this time, the hot air in the signal anti-interference device just overflows to the outside through the heat dissipation holes on both sides of the signal anti-interference device, and the cold air can accelerate the overflow of the hot air, further increasing the heat dissipation effect of the signal anti-interference device;

[0027] S4. When a fault or fire occurs at the plug-in position of the cable and the port of the signal anti-interference device, the temperature sensor is close to the plug-in position of the cable and the port of the signal anti-interference device. The temperature sensor detects that the temperature reaches a certain threshold and transmits the signal to the alarm light and the buzzer. The alarm light emits an alarm light and the buzzer emits a buzzer to alarm, notifying the staff to carry out maintenance in time;

[0028] S5. In addition, the U-shaped shielding plates rotate toward the middle under the action of the torsion spring, and the two U-shaped shielding plates can just block the heat dissipation holes on both sides of the signal anti-interference device to prevent the interference signal from interfering with the inside of the signal anti-interference device through the heat dissipation holes. In addition, the cold air moving upward through the second ventilation hole can be blown to the top of the signal anti-interference device through the guidance of the arc-shaped air guide plate, which not only dissipates heat and cools the top of the signal anti-interference device, but also can blow away the dust on the top of the signal anti-interference device to prevent dust from accumulating on the top of the signal anti-interference device and hindering the normal heat dissipation of the signal anti-interference device.

[0029] In the present invention, the heat dissipation structure includes two first heat dissipation groups arranged on both sides of the mounting plate, the first heat dissipation group is composed of a plurality of second ventilation holes, the bottom inner wall of the placement groove is provided with a plurality of first ventilation holes, and two second heat dissipation groups are provided in the mounting plate, the second heat dissipation group is composed of a plurality of third ventilation holes; cold air is dissipated and cooled down the bottom of the signal anti-interference device through the first ventilation holes, and the cold air is also blown to the plug-in position of the cable and the port of the signal anti-interference device through the third ventilation holes, so as to cool the plug-in position of the cable and the port of the signal anti-interference device, and the cold air is blown through the second ventilation holes just to disperse the hot air overflowing from the heat dissipation holes on both sides of the signal anti-interference device to the outside, thereby further increasing the heat dissipation effect of the signal anti-interference device;

[0030] In the present invention, a plurality of extrusion plates are slidably penetrated in the U-shaped frame, a plurality of fixing frames are fixed on the side of the upper base plate close to the signal anti-interference device, a sleeve is rotatably connected to one side of the fixing frame through a connecting rod, and one end of the extrusion plate close to the lower base plate slides and extends into the sleeve; the upper base plate drives the fixing frame to move upward, and the fixing frame drives the extrusion plate to move toward the middle through the connecting rod, and the cooperation of the second spring and the extrusion plate preliminarily clamps the placement groove, and when the upper base plate moves downward and resets, the sleeve resets a certain distance under the action of the connecting rod, and the elastic force of the second spring can still push the extrusion plate to pressurize and fix the signal anti-interference device, so that the signal anti-interference device can be easily fixed, and the installation and disassembly are extremely convenient;

[0031] In the present invention, a U-shaped shielding plate is fixed to the outer wall of the rotating shaft, and an arc-shaped air guide plate is fixed to the side of the U-shaped shielding plate close to the signal anti-interference device, and the U-shaped shielding plate, the arc-shaped air guide plate and the second ventilation hole cooperate with each other; under the action of the torsion spring, the two U-shaped shielding plates can just block the heat dissipation holes on both sides of the signal anti-interference device to prevent the interference signal from interfering with the inside of the signal anti-interference device through the heat dissipation holes, and in addition, the cold air moving upward through the second ventilation hole can be guided by the arc-shaped air guide plate to blow to the top of the signal anti-interference device, which not only dissipates heat and cools the top of the signal anti-interference device, but also can blow away the dust on the top of the signal anti-interference device to prevent dust from accumulating on the top of the signal anti-interference device and hindering the normal heat dissipation of the signal anti-interference device;

[0032] In the present invention, the same fixing pin is welded on both sides of the top of the lower base plate, the outer wall sliding sleeves of the two fixing pins are provided with the same upper base plate, and the cooperation between the upper base plate and the lower base plate is used to clamp the cable, and the cable is aligned with the central axis of the port tube of the signal anti-interference device; through the cooperation of the first spring and the fixing pin, the lower base plate and the upper base plate can clamp the cable to avoid bending at the connection between the cable and the wiring port of the signal anti-interference device.

[0033] In the present invention, the cable clamping and the signal anti-interference device fixing can be completed simultaneously by moving the upper base plate up and down, which not only ensures the stability of the connection between the cable and the port of the signal anti-interference device, but also ensures the convenience of installation and disassembly of the signal anti-interference device. In addition, the signal anti-interference device can be dissipated in all directions through the first ventilation hole, the third ventilation hole and the second ventilation hole, and the cooperation of the U-shaped shielding plate and the arc-shaped air guide plate not only further dissipates the heat of the signal anti-interference device, but also increases the overall anti-interference ability of the signal anti-interference device.

Since the third ventilation hole 26 is narrow at the top and wide at the bottom, and the cross-sectional area changes from large to small, the flow rate of cold air passing through the third ventilation hole 26 is increased, and the plug-in position of the cable and the port of the signal anti-interference device 3 can be effectively cooled, and the cold air flows upward through the second ventilation hole 25. At this time, the hot air in the signal anti-interference device 3 just overflows to the outside through the heat dissipation holes on both sides of the signal anti-interference device 3, and then the cold air can accelerate the overflow of the hot air, further increasing the heat dissipation effect of the signal anti-interference device 3.

[0056] Example 2

[0057] refer to Fig. 9 and Fig.10 , improved on the basis of Example 1: two base plates 34 are welded on both sides of the top of the mounting plate 1, and the two base plates 34 on the same side are rotatably connected with the same rotating shaft 35, and a U-shaped shielding plate 37 is fixed to the outer wall of the rotating shaft 35, and two torsion springs 36 are sleeved on the outer wall of the rotating shaft 35, and the ends of the two torsion springs 36 close to each other are respectively fixedly connected to the two sides of the U-shaped shielding plate 37, and the ends of the two torsion springs 36 away from each other are respectively fixedly connected to the two base plates 34, and the side of the U-shaped shielding plate 37 close to the signal anti-interference device 3 is fixed with an arc-shaped air guide plate 38 by bolts, and the U-shaped shielding plate 37, the arc-shaped air guide plate 38 and the second ventilation hole 25 cooperates with each other; under the action of the torsion spring 36, the two U-shaped shielding plates 37 rotate toward the middle, and the two U-shaped shielding plates 37 can just block the heat dissipation holes on both sides of the signal anti-interference device 3, so as to prevent the interference signal from interfering with the inside of the signal anti-interference device 3 through the heat dissipation holes. In addition, the cold air moving upward through the second ventilation hole 25 can be blown to the top of the signal anti-interference device 3 through the guidance of the arc-shaped air guide plate 38, which not only dissipates heat and cools the top of the signal anti-interference device 3, but also can blow away the dust on the top of the signal anti-interference device 3, so as to prevent dust from accumulating on the top of the signal anti-interference device 3 and hindering the normal heat dissipation of the signal anti-interference device 3.

[0058] A method for using a DC power line carrier anti-interference device for distributed energy control includes the following steps:

[0059] S1. Move the two U-shaped shielding plates 37 to both sides, place the signal anti-interference device 3 in the placement slot 2, and drive the upper base plate 9 to move upward through the pull belt 12. The external cables pass through the upper base plate 9 and the lower base plate 8 and are plugged into the port of the signal anti-interference device 3. Release the pull on the upper base plate 9, and the upper base plate 9 moves downward under the elastic force of the first spring 11. At this time, the lower base plate 8 and the upper base plate 9 complete the clamping of the cable, and the central axis of the cable coincides with the axis of the port of the signal anti-interference device 3, so that the cable can always be kept level with the port of the signal anti-interference device 3, avoiding the bending of the cable in the later stage;

[0060] S2. In addition, when the upper base plate 9 moves upward, the fixing frame 19 is driven to move upward. The fixing frame 19 drives the extrusion plate 16 and the sleeve 17 to move toward the direction of the signal anti-interference device 3 through the connecting rod 20. The placement slot 2 is initially clamped by the cooperation of the second spring 18 and the extrusion plate 16. Due to the cooperation of the first inclined surface 39 and the second inclined surface 40, the extrusion plate 16 can not only generate downward pressure on the signal anti-interference device 3, but also generate an extrusion force toward the middle of the signal anti-interference device 3, so that the fixation of the signal anti-interference device 3 is quite stable. When the upper base plate 9 moves downward and resets, the sleeve 17 resets a certain distance under the action of the connecting rod 20, and the elastic force of the second spring 18 can still push the extrusion plate 16 to pressurize and fix the signal anti-interference device 3, so that the signal anti-interference device 3 can be easily fixed, and the installation and disassembly are extremely convenient. When the extrusion plate 16 generates a downward extrusion force on the signal anti-interference device 3 through the second inclined surface 40, the signal anti-interference device 3 squeezes the grounding guide rod 27 to move downward, and the grounding guide rod 27 is just grounded, thereby increasing the anti-interference ability of the signal anti-interference device 3;

[0061] S3. When ventilation and heat dissipation are required, start the ventilation fan 23, and the ventilation fan 23 blows cold air from bottom to top. The cold air dissipates heat and cools down the bottom of the signal anti-interference device 3 through the first ventilation hole 24, and the cold air also blows to the plug-in position of the cable and the port of the signal anti-interference device 3 through the third ventilation hole 26. Since the third ventilation hole 26 is narrow at the top and wide at the bottom, and the cross-sectional area changes from large to small, the flow rate of the cold air through the third ventilation hole 26 is increased, so that the plug-in position of the cable and the port of the signal anti-interference device 3 can be effectively cooled, and the cold air flows upward through the second ventilation hole 25. At this time, the hot air in the signal anti-interference device 3 just overflows to the outside through the heat dissipation holes on both sides of the signal anti-interference device 3, and then the cold air can accelerate the overflow of the hot air, further increasing the heat dissipation effect of the signal anti-interference device 3;

[0062] S4, when a fault or fire occurs at the plug-in position of the cable and the port of the signal anti-interference device 3, the temperature sensor 30 is close to the plug-in position of the cable and the port of the signal anti-interference device 3, and the temperature sensor 30 detects that the temperature reaches a certain threshold, and transmits the signal to the alarm light 31 and the buzzer 32, the alarm light 31 emits an alarm light, and the buzzer 32 emits a buzzer sound to alarm, notifying the staff to carry out maintenance in time;

[0063] S5. In addition, the U-shaped shielding plates 37 rotate toward the middle under the action of the torsion spring 36, and the two U-shaped shielding plates 37 can just block the heat dissipation holes on both sides of the signal anti-interference device 3 to prevent the interference signal from interfering with the inside of the signal anti-interference device 3 through the heat dissipation holes. In addition, the cold air moving upward through the second ventilation hole 25 can be blown to the top of the signal anti-interference device 3 through the guidance of the arc-shaped air guide plate 38, which not only dissipates heat and cools the top of the signal anti-interference device 3, but also can blow away the dust on the top of the signal anti-interference device 3 to prevent dust from accumulating on the top of the signal anti-interference device 3 and hindering the normal heat dissipation of the signal anti-interference device 3.

Move the two U-shaped shielding plates (37) to the sides, place the signal anti-interference device (3) in the placement groove (2), and drive the upper base plate (9) upward through the pull belt (12). The external cables pass through the upper base plate (9) and the lower base plate (8) and are plugged into the port of the signal anti-interference device (3). Release the lifting of the upper base plate (9). The upper base plate (9) moves downward under the elastic force of the first spring (11). At this time, the lower base plate (8) and the upper base plate (9) complete the clamping of the cable, and the central axis of the cable coincides with the axis of the port of the signal anti-interference device (3), so that the cable can always be kept level with the port of the signal anti-interference device (3); S2. In addition, when the upper base plate (9) moves upward, the fixing frame (19) is driven to move upward. The fixing frame (19) drives the extrusion plate (16) and the sleeve (17) to move in the direction of the signal anti-interference device (3) through the connecting rod (20). The placement groove (2) is initially clamped by the cooperation of the second spring (18) and the extrusion plate (16). Due to the cooperation of the first inclined surface (39) and the second inclined surface (40), the extrusion plate (16) can not only generate downward pressure on the signal anti-interference device (3), but also generate an extrusion force toward the middle of the signal anti-interference device (3), so that the fixing of the signal anti-interference device (3) is equivalent to The upper base plate (9) is stable. When the upper base plate (9) moves downward and resets, the sleeve (17) resets a certain distance under the action of the connecting rod (20), and the elastic force of the second spring (18) can still push the extrusion plate (16) to pressurize and fix the signal anti-interference device (3), so that the signal anti-interference device (3) can be easily fixed. The installation and disassembly are extremely convenient. When the extrusion plate (16) generates a downward extrusion force on the signal anti-interference device (3) through the second inclined surface (40), the signal anti-interference device (3) squeezes the grounding guide rod (27) downward, and the grounding guide rod (27) is just grounded, thereby increasing the anti-interference ability of the signal anti-interference device (3); S3. When ventilation and heat dissipation are required, the ventilation fan (23) is started. The ventilation fan (23) blows cold air from bottom to top. The cold air passes through the first ventilation hole (24) to dissipate heat and cool the bottom of the signal anti-interference device (3). The cold air also passes through the third ventilation hole (26) to the plug-in position of the cable and the port of the signal anti-interference device (3). Since the third ventilation hole (26) is narrow at the top and wide at the bottom, and the cross-sectional area changes from large to small, the flow rate of the cold air passing through the third ventilation hole (26) is increased, thereby effectively cooling the plug-in position of the cable and the port of the signal anti-interference device (3). The cold air flows upward through the second ventilation hole (25). At this time, the hot air in the signal anti-interference device (3) just overflows to the outside through the heat dissipation holes on both sides of the signal anti-interference device (3). The cold air can accelerate the overflow of the hot air, further increasing the heat dissipation effect of the signal anti-interference device (3). S4. When a fault or fire occurs at the plug-in position of the cable and the port of the signal anti-interference device (3), the temperature sensor (30) is close to the plug-in position of the cable and the port of the signal anti-interference device (3). The temperature sensor (30) detects that the temperature reaches a certain threshold value and transmits a signal to the alarm light (31) and the buzzer (32). The alarm light (31) emits an alarm light and the buzzer (32) emits a buzzer sound to warn the staff to carry out maintenance in time. S5. In addition, the U-shaped shielding plates (37) are rotated toward the middle under the action of the torsion spring (36). The two U-shaped shielding plates (37) can just cover the heat dissipation holes on both sides of the signal anti-interference device (3), thereby preventing the interference signal from interfering with the inside of the signal anti-interference device (3) through the heat dissipation holes. In addition, the cold air that moves upward through the second ventilation hole (25) can be guided by the arc-shaped air guide plate (38) to the top of the signal anti-interference device (3), which not only dissipates heat and cools the top of the signal anti-interference device (3), but also can blow away the dust on the top of the signal anti-interference device (3).
