Description

Technical Field

[0001] The present invention relates to the technical field of power data acquisition devices, and particularly to a power data acquisition device with multi-interface protection. Background Art

[0002] Power data acquisition plays an increasingly important role in the operation and management of power systems. Power data acquisition devices are key devices connecting the power grid and various electrical equipment. The data acquisition device can monitor and collect various parameters of electrical equipment in real time, and transmit power data to the intelligent distribution network through an antenna. These data can directly reflect the operation status of the power system, which is crucial for subsequent analysis, dispatching, and management. However, there are still the following deficiencies after specific use and comparison with the prior art:

[0003] When the connecting wire is inserted into the inside of the cable connection port, since the diameter of the cable connection port is relatively small, the connecting wire is prone to tilt during insertion, which easily causes uneven friction between the connecting wire and the metal contacts inside the cable connection port, exacerbates the wear degree, and shortens the service life of the cable connection port. Moreover, when the connecting wire is plugged and unplugged multiple times, the skewed connecting wire will cause extrusion and deformation inside the cable connection port, which not only affects the stability and accuracy of data transmission, but also easily leads to signal attenuation and interruption.

[0004] Therefore, the present invention proposes a power data acquisition device with multi-interface protection to make up for and improve the deficiencies of the prior art. Summary of the Invention

On the upper surface of the fixing ring, fixing strips are fixedly connected symmetrically in the front and rear directions.

[0008] More preferably, on the inner side of the upper surface of the guide plate, a blocking plate is rotatably connected. On the outer surface of the guide plate, a limiting frame is fixedly connected. Inside the limiting frame, a cylinder is rotatably connected. The upper surface of the cylinder is connected through a gas valve. The output end of the cylinder is rotatably connected to the side of the blocking plate close to the limiting frame. On the inner side of the blocking plate away from the limiting frame, a plurality of rolling members are linearly rotatably connected.

[0009] More preferably, the output end of the telescopic member is fixedly connected to an extrusion member on one side away from the connecting line, the two sides of the upper surface of the extrusion member are inclined outward, the inclined surface on the right side of one end of the extrusion member away from the locking member is slidably connected to a sliding rod, the outer surface of the sliding rod away from the extrusion member is fixedly connected to a release frame, and the inner side of the bottom of the release frame is fixedly connected to the outer surface of the sliding member.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention can insert the connecting wire into the cable connection port straightly through the first guide frame, which can reduce the bending and twisting of the connecting wire during the insertion process, thereby reducing the risk of damage to the connecting wire and the cable connection port, and the connecting wire can be inserted downwardly in the center by squeezing the guide plate inward, ensuring that the contact point between the connecting wire and the cable connection port is in the best position, maximizing the contact area, thereby improving the tightness and stability of the contact.

[0018] 2. When the connecting wire is inserted into the cable connection port, the inner side of the positioning member can be clamped to the outer surface of the connecting wire, thereby providing a stable fixing effect, preventing the connecting member from accidentally coming off or loosening under the action of external factors such as vibration and impact. When the connecting wire is pulled upward, the positioning member will drive the clamping member to move upward at the same time, enabling the connecting wire to be pulled out straight from the inside of the cable connection port, reducing the friction and extrusion between the insulating layer of the connecting wire and the cable connection port or other components, thereby protecting the integrity of the connecting wire.

[0019] 3. When the connecting member is inserted, the blocking plate will slowly turn outward, which can slow down the insertion speed of the connecting member, reduce the physical impact between the connecting member and the cable connection port, and avoid the instantaneous high stress suffered by the connecting member due to rapid insertion, thereby protecting the integrity and service life of the connecting member.

[0020] 4. When the connecting wire is pulled upward, it drives the sliding member to move to the right, which can automatically release the connecting wire, reduce the friction and extrusion of the sliding member on the outer surface of the connecting wire, thereby reducing the degree of wear and extending the service life of the connecting wire.

The outer surface of the sliding frame 18 is fixedly connected with a pressure spring 110. The inner side of the pressure spring 110 is fixedly connected to the outer surface of the support frame 17. The pressure spring 110 is used to drive the sliding frame 18 to reset. The right side of each square hole on the upper surface of the power quality analyzer 1 is fixedly connected with a guide member 19. The guide members 19 are all slidably connected with a U-shaped bar 112. The guide member 19 is used to limit the U-shaped bar 112 from sliding inside the guide member 19. The lower surface of the U-shaped bar 112 is fixedly connected with a compression spring 114. The lower surface of the compression spring 114 is fixedly connected to the inner side of the guide member 19.

The connecting line 11 can be inserted downward in the center by extruding inward through the guide plate 14, ensuring that the contact point between the connecting line 11 and the cable connecting port 13 is in the best position, maximizing the contact area, thereby improving the tightness and stability of the contact.

[0040] Reference Figure 8 and Figure 9 As shown, a power data acquisition device with multi-interface protection. On both sides of each square hole on the upper surface of the power quality analyzer 1, there are fixed clamping frames 2. Inside the clamping frames 2 near the connecting wire 11, there are sliding second guiding frames 21. The clamping frames 2 are used to limit the sliding of the second guiding frames 21 inside the clamping frames 2. Between the inner sides of the tops of two adjacent second guiding frames 21, there is a fixed clamping member 22. On both the left and right sides of the clamping member 22, there are sliding positioning members 23. The outer surfaces of the positioning members 23 slide through the outer surface of the clamping member 22. The inner sides of the positioning members 23 are in clamping fit with the outer surface of the connecting wire 11. On the side of the upper surface of the positioning member 23 away from the clamping member 22, there is a fixed tension spring 24. One end of the tension spring 24 away from the positioning member 23 is fixed to the outer surface of the clamping member 22.

On the upper surface of the clamping member 22, there are symmetrically fixed telescopic members 25 in the front and back directions. Between the upper surfaces of the two telescopic members 25, there is a fixed ring 26. On the upper surface of the fixed ring 26, there are symmetrically fixed fixing bars 27 in the front and back directions. The fixing bars 27 are used to pull the fixed ring 26. By pulling the fixed ring 26 upward, the connecting wire 11 can be driven to move upward through the positioning member 23 and the clamping member 22, enabling the connecting wire 11 to be pulled out straight from the inside of the cable connection port 13, reducing the friction and extrusion between the insulating layer of the connecting wire 11 and the cable connection port 13 or other components, thereby protecting the integrity of the connecting wire 11.

[0041] Reference Figures 10 to 12 As shown, a power data acquisition device with multi-interface protection. On the inner side of the upper surface of the guiding plate 14, there is a rotatably connected blocking plate 3. At both ends of the upper surface of the blocking plate 3, there are fixed winding torsion springs 34. One end of the torsion spring 34 away from the blocking plate 3 is fixed to the inner side of the guiding plate 14. The torsion spring 34 is used to drive the blocking plate 3 to reset.

The air cylinder 32 is used to slow down the swinging speed of the blocking plate 3. On the inner side of the blocking plate 3 away from the limiting frame 31, there are a plurality of rolling members 35 rotatably connected in a straight line. The rolling members 35 are used to make the insertion of the connecting wire 11 smoother. When inserting the connecting wire 11, the blocking plate 3 will slowly turn outward, which can slow down the insertion speed of the connecting wire 11 and reduce the physical impact between the connecting wire 11 and the cable connection port 13.

[0042] Reference Figure 13 andFigure 14 As shown, a power data acquisition device with multi-interface protection, the output end of the telescopic member 25 is fixedly connected to the side away from the connecting line 11 with an extrusion member 4, the two sides of the upper surface of the extrusion member 4 are inclined outward, and the inclined surface on the right side of the extrusion member 4 is slidably connected with a sliding rod 42, the inclined surface on the upper surface of the extrusion member 4 is pressed and matched with the outer surface of the sliding rod 42, the extrusion member 4 is used to drive the sliding rod 42 to move rightward, the outer surface on the right side of the sliding rod 42 is fixedly connected with a release frame 41, the sliding rod 42 is used to drive the release frame 41 to move rightward at the same time, the inner side of the bottom of the release frame 41 is fixedly connected to the outer surface of the sliding member 113, the release frame 41 is used to drive the sliding member 113 to move rightward, the outer surface of the bottom of the release frame 41 A limiting rod 43 is fixedly connected to the surface, and the outer surface of the limiting rod 43 slides through the outer surface of the bottom of the second guide frame 21.

A reset spring 44 is fixedly connected to the right side of the bottom of the release frame 41, and the end of the reset spring 44 away from the release frame 41 is fixedly connected to the U-shaped bar 112. The reset spring 44 is used to drive the release frame 41 to reset, and when the connecting line 11 is pulled upward, the sliding member 113 is driven to move to the right, so that the connecting line 11 can be automatically released, reducing the friction and extrusion of the sliding member 113 on the outer surface of the connecting line 11.

[0043] The complete working principle and steps of the above embodiment are as follows:

[0044] refer to Figures 1 to 7 As shown, when the power data acquisition device is in the initial state, the guide plate 14 is slidably connected to the outer surface of the cable connection port 13 and is in an unfolded state, the storage spring 16, the sliding frame 18 and the compression spring 114 are all in a naturally relaxed state, and the lower surface of the extrusion frame 111 has not yet been fitted with the round rod at the right end of the sliding frame 18;

[0045] When the power data acquisition device is in use, when inserting the connection line 11 into the inside of the cable connection port 13, it is first necessary to insert it into the inside of the first guide frame 12 so that the connection line 11 can be inserted straight down. When the connection line 11 is inserted downward, the outer surface of the connection line 11 will contact the left side of the sliding member 113, and the sliding member 113 is slidably connected to the upper surface of the U-shaped bar 112. As the connection line 11 is inserted downward, it will drive the sliding member 113 to move downward at the same time, and the sliding member 113 will also drive the U-shaped bar 112 to slide downward inside the guide member 19 at the same time. When the U-shaped bar 112 slides downward, it will drive the compression spring 114 fixedly connected to the lower surface of the U-shaped bar 112 to slide downward at the same time, prompting the compression spring 114 to move to the compressed state. And the right end of the U-shaped bar 112 is fixedly connected to the left end of the extrusion frame 111. As the U-shaped bar 112 slides downward, it will drive the extrusion frame 111 to slide downward at the same time. The lower surface of the extrusion frame 111 is inclined inward. As the extrusion frame 111 moves downward, it will squeeze the round rod on the right side of the sliding frame 18, prompting the sliding frame 18 to drive the support frame 17 to move inward at the same time through the pressure spring 110. When the support frame 17 moves inward, it will drive the guide frame 15 fixedly connected to the top of the left side of the support frame 17 to slide at the same time. When the guide frame 15 slides toward the side close to the cable connection port 13, it will drive the energy storage spring 16 fixedly connected to the side of the guide frame 15 away from the cable connection port 13 to move to the stretched state. One end of the guide frame 15 close to the guide plate 14 is fixedly connected to the side of the guide plate 14 away from the cable connection port 13. As the guide frame 15 slides toward the side close to the cable connection port 13, it will drive the guide plate 14 to move at the same time, prompting the inner side of the guide plate 14 to limit the outer surface of the bottom of the connection line 11. When the inner side of the guide plate 14 contacts the outer surface of the bottom of the connection line 11, the guide plate 14 stops moving. At this time, the extrusion frame 111 continues to move downward to squeeze the cylinder on the sliding frame 18. At this time, the sliding frame 18 slides on the support frame 17, and the pressure spring 110 is compressed. At this time, the pressure spring 110 can play a buffering role, preventing the extrusion frame 111 from continuing to drive the guide plate 14 to squeeze the outer surface of the connection line 11 by driving the sliding frame 18, and preventing the inner side of the guide plate 14 from causing a forced squeeze on the outer surface of the bottom of the connection line 11, and preventing the connection line 11 from being damaged and deformed due to excessive extrusion. Through the guidance of the connection line 11 by the guide plate 14, the connection line 11 can be inserted straight down in the middle, ensuring that the contact point between the connection line 11 and the cable connection port 13 is in the best position, maximizing the contact area, thereby improving the tightness and stability of the contact.

[0046] When the power data acquisition device is not in use and the connection line 11 is pulled out from the inside of the cable connection port 13, first, the sliding member 113 is pushed to the right on the upper surface of the U-shaped bar 112, and the upper surface of the sliding member 113 is separated from the outer surface of the connection line 11. At this time, the compression spring 114 in the compressed state will drive the U-shaped bar 112 to move upward inside the guide member 19. When the U-shaped bar 112 moves upward, it will drive the extrusion frame 111 to move upward at the same time. At this time, the lower surface of the extrusion frame 111 will be separated from the circular rod at the right end of the sliding frame 18, and the compression spring 110 in the compressed state will drive the sliding frame 18 to reset, and the energy storage spring 16 in the stretched state will drive the guide plate 14 to move back to the initial state on the side away from the cable connection port 13.

[0047] Reference Figure 8 and Figure 9 As shown in

[0048] , when the power data acquisition device is in the initial state, the telescopic member 25 is in the extended state, the positioning member 23 is slidably connected to the inside of the clamping member 22, and the tension spring 24 is in the natural relaxed state; When the connection line 11 is inserted into the inside of the cable connection port 13, it needs to pass through the inside of the fixing ring 26 and the clamping member 22. When the connection line 11 passes through the inside of the fixing ring 26, it can guide and limit the connection line 11, enabling the connection line 11 to be vertically inserted into the inside of the cable connection port 13, avoiding deviation when the connection line 11 is inserted. As the connection line 11 is inserted downward, the annular groove on the outer surface of the connection line 11 will be clamped to the inside of the positioning member 23. As the connection line 11 continues to move downward, it will cause the positioning member 23 to be extruded outward. Since the upper surface of the positioning member 23 close to the clamping member 22 is fixedly connected to the end of the tension spring 24 away from the connection line 11, when the positioning member 23 moves outward, it will drive the tension spring 24 to move outward at the same time, causing the tension spring 24 to move to the stretched state. At this time, the inside of the positioning member 23 can be clamped in the annular groove on the outer surface of the connection line 11, thus playing a fixing role and preventing the connection line 11 from accidentally coming out or loosening under the action of external factors such as vibration and impact;

[0049] When the power data acquisition device is no longer in use, the inner side of the positioning member 23 will be clamped in the annular groove on the outer surface of the connecting wire 11. When the operator needs to pull out the connecting wire 11, first slide the sliding member 113 to the right on the upper surface of the U-shaped strip 112 so that the upper surface of the sliding member 113 is separated from the fitting of the connecting wire 11. Then pull up the outer surface of the fixing strip 27. When pulling up the fixing strip 27, it is possible to avoid directly pulling the connecting wire 11, thereby avoiding damage to the connecting wire 11 and extending the service life of the connecting wire 11. As the fixing strip 27 moves upward, it will drive the telescopic member 25 to move simultaneously through the fixing ring 26. When the telescopic member 25 moves upward, it will drive the bottom clamping member 22 to move simultaneously. At this time, when the clamping member 22 drives the positioning member 23 to slide upward, the inner side of the positioning member 23 will drive the connecting wire 11 to move simultaneously. Since the outer surfaces on both sides of the clamping member 22 are fixedly connected to the inner side of the second guide frame 21, as the clamping member 22 slides upward, the second guide frame 21 will slide simultaneously inside the clamping frame 2. At this time, the connecting wire 11 can be pulled out straight upward following the clamping member 22, reducing the friction and extrusion between the insulating layer of the connecting wire 11 and the cable connection port 13 or other components, thereby protecting the integrity of the connecting wire 11. As the bottom of the connecting wire 11 disengages from the inside of the cable connection port 13, the operator can push the positioning members 23 on both the left and right sides of the outer surface of the clamping member 22 outward, causing the inner side of the positioning member 23 to disengage from the annular groove on the outer surface of the connecting wire 11. At this time, the connecting wire 11 can be completely removed.

[0050] Reference Figures 10 to 12 As shown in the reference, when the connecting wire 11 is inserted into the cable connection port 13, the outer surface of the connecting wire 11 will fit against the outer surface of the blocking plate 3, and the blocking plate 3 is flipped outward. Both ends of the top of the blocking plate 3 are fixedly sleeved inside the torsion spring 34. As the blocking plate 3 is flipped outward, it will cause the torsion spring 34 to rotate into a state of storing energy, and it will also cause the output end of the air cylinder 32 to contract inward. When the air cylinder 32 contracts inward, the gas inside the air cylinder 32 will be discharged from the air valve 33 connected to the upper surface of the air cylinder 32. When the connecting wire 11 is inserted inward, the insertion speed can be slowed down, reducing the physical impact between the connecting wire 11 and the cable connection port 13, and avoiding the instantaneous high stress suffered by the connecting wire 11 due to rapid insertion, thereby protecting the integrity of the connecting component and extending its service life.

[0051] When the connecting wire 11 is pulled out from inside the sliding member 113, the torsion spring 34 in the state of storing energy will drive the blocking plate 3 to swing inward, and when the blocking plate 3 swings inward, it will drive the output end of the air cylinder 32 to extend outward simultaneously. As the output end of the air cylinder 32 extends outward, the outside air will enter the inside of the air cylinder 32 through the air valve 33 for resetting.

[0052] Reference Figure 13 and Figure 14As shown above and described in the previous text, before people need to pull out the connection line 11 upward, they need to manually move the sliding member 113 to the right to disengage from the connection line 11 first, so that the guiding plate 14 can be separated from the connection line 11. Only in this way can people pull out the connection line 11 upward. If the guiding plate 14 is not separated from the connection line 11 and the connection line 11 is directly pulled out upward, it will cause friction between the connection line 11 and the guiding plate 14, thereby damaging the connection line 11 through friction. And in the previous text, it is necessary to manually move the sliding member 113 to the right, which is very cumbersome. Therefore, the following components are provided to enable the sliding member 113 to automatically move to the right and reset:

[0053] When pulling out the connection line 11 from the inside of the cable connection port 13, it is necessary to hold the fixed strip 27 and pull it upward. When the fixed strip 27 moves upward, it will drive the telescopic member 25 to move upward through the fixed ring 26. When the telescopic member 25 moves upward, it will drive the clamping member 22 and the second guiding frame 21 to move upward. When the second guiding frame 21 moves upward, it will drive the limiting rod 43 to move upward. When the limiting rod 43 moves upward and contacts the upper part of the clamping frame 2, the limiting rod 43 stops moving upward. The limiting rod 43 drives the second guiding frame 21, the release frame 41, and the limiting rod 43 to stop moving upward. At this time, the fixed ring 26 continues to move upward, which will drive the output end of the telescopic member 25 to continue to move upward. As the output end of the telescopic member 25 moves upward, it can drive the pressing member 4 to move simultaneously. As the pressing member 4 moves upward, the inclined surface on the right side of the pressing member 4 can press the sliding rod 42 and drive the sliding rod 42 to slide to the right. When the sliding rod 42 slides to the right, it will drive the release frame 41 to slide simultaneously. When the release frame 41 moves to the right, it will disengage from the second guiding frame 21. At the same time, when the release frame 41 slides to the right, it will compress the return spring 44 into a compressed state, and will also drive the sliding member 113 to slide to the right. After the sliding member 113 moves to the right and is separated from the connection line 11, the guiding plate 14 will automatically reset and be separated from the connection line 11. At this time, when the fixed ring 26 continues to move upward, it will drive the pressing member 4, the telescopic member 25, and the clamping member 22 to move upward synchronously. And the clamping member 22 will drive the second guiding frame 21 to move upward. The left part of the limiting rod 43 always abuts against the right part of the second guiding frame 21, so that the limiting rod 43 cannot move to the left to reset, and at the same time, the sliding rod 42, the release frame 41, and the sliding member 113 cannot move to the left to reset, thereby enabling the guiding plate 14 to always maintain a state of being away from the connection line 11. In this way, when the clamping member 22 moves upward, it will drive the connection line 11 to be pulled out upward through the limiting rod 43. During the pulling out process, the connection line 11 does not contact the sliding member 113 and the guiding plate 14 respectively, which can avoid the sliding member 113 and the guiding plate 14 from causing friction and extrusion to the outer surface of the connection line 11, thereby reducing the wear degree and prolonging the service life of the connection line 11;

[0054] After completely pulling out the connecting line 11, the fixing bar 27 can be pushed downward to reset, thereby driving components such as the telescopic member 25 and the second guide frame 21 to move downward for reset. When the sliding fit position below the clamping member 22 coincides with that of the limiting rod 43, the reset spring 44 in the compressed state will drive the release frame 41 to move leftward. When the release frame 41 moves leftward, it will drive the limiting rod 43 to move simultaneously, prompting the left end of the limiting rod 43 to re-insert into the inner side of the outer surface of the second guide frame 21. Moreover, when the release frame 41 moves leftward, it will drive the sliding member 113 to move simultaneously for reset, so that there is no need for staff to manually reset the sliding member 113.
