Description

Technical Field

[0001] The present invention relates to the field of power technology, and in particular to a remote control switching device for trip coils. Background Art

[0002] Power trip coils are very important secondary power equipment, generally installed in the power line system loop for opening and closing operations of power lines to achieve on-off control of transmission lines.

[0003] Installing trip coils on the loop is an important means to ensure the safe operation of the power system. The trip coil is an obvious disconnection point visible to the naked eye, which provides great convenience for maintenance and operation, but also adds a disconnection point that cannot be fully monitored and controlled in a closed loop. Due to the particularity of the trip coil, under normal conditions (when there is no tripping command), both sides cannot be energized simultaneously. During operation, the switching of the trip coil is manually operated. Therefore, in actual operation, the phenomenon of system losses caused by improper switching of the trip coil occurs from time to time. The intelligent trip coil system that can be remotely controlled and detected has successfully solved this problem. In addition, for unattended substations, the switching state of the trip coil is even more crucial. For unattended substations, sometimes, in order to switch the operation mode or cooperate with the maintenance of relevant lines, etc., in order to effectively prevent misoperation and personal injury during maintenance, it is necessary to switch the position of the relevant trip coil. However, simply sending people and vehicles to the unattended station to switch the trip coil remotely will be time-consuming and laborious, not only inefficient but also have various safety hazards.

[0004] However, there is currently no trip coil device that is safe, has excellent structure, is durable and easy to use, has low cost and can be remotely controlled. Summary of the Invention

[0011] Further, there is an idle stroke formed between the bushing and the spur gear by the rotational distance between the dial and the transmission block.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used with reference to the accompanying drawings. However, words such as "front", "rear", "left", "right", "upper", and "lower" should be understood as convenient terms and should not be understood as limiting terms.

[0040] As Figure 1 shown in FIG. -2, this embodiment provides a remote control trip and close link device, which includes a link 110, a mounting panel 100, and an intelligent link detection device 120.

[0041] Specifically, the link 110 includes a handle 113, a base 114, and an electrode 115; the electrode 115 is installed on the base 114 through a fixing nut 116. One side of the base 114 passes through the mounting panel 100 and is fixedly connected to the outer shell 1211 of the intelligent link detection device 120 through a screw 117. One end of the handle 113 passes through the base 114 and the mounting panel 100 and is inserted into the intelligent link detection device 120; the interior of the outer shell 1211 of the intelligent link detection device 120 is hollow. One end of the outer shell 1211 away from the link 110 is provided with a detachable rear cover 1212 for closing the outer shell 1211. Inside the intelligent link detection device 120, there are provided a linear movement module, a rotation module, a main shaft module, a motor 125, and a circuit control module 126 for cooperating with the handle 113 for manual or electric trip and close.

[0042] Further, as a preferred mode of this embodiment, the linear movement module and the rotation module are arranged on both sides of the main shaft module, and both the linear movement module and the rotation module are actuated by the motor 125; wherein, the linear movement module is slidably connected to the main shaft module, the rotation module is drivingly connected to the main shaft module, and the main shaft module is connected to the handle 113; the circuit control module 126 can determine the position of the handle 113 through the position change of the main shaft module.

[0043] Further, as a preferred embodiment of the present embodiment, inward grooves are provided on both outer sides of the housing 1211 of the intelligent pressure plate detection device 120. A bolt perforation mounting plate for mating with the mounting base 114 is formed on the side of the groove close to the mounting panel 100. Two groups of screw holes 12111 are provided on the bolt perforation mounting plate, and each group of screw holes 12111 is provided in multiple numbers to be compatible with mounting pressure plates 110 of different lengths.

[0044] Further, as a preferred embodiment of the present embodiment, a chute is provided at the end of the handle 113 exposed inside the intelligent pressure plate detection device 120, and a transparent cover 111 is installed through the chute; a label paper 112 is further provided between the transparent cover 111 and the handle 113; the remote control pressure plate device can be identified through the label paper 112.

[0045] In this embodiment, the specific structures and settings of the linear movement module, the rotation module, the main shaft module, the motor 125, and the circuit control module 126 are also given, as Figure 2 shown;

[0046] (1) The linear movement module includes a rotating shaft 1225, a screw 1221, a slide bar 1222, a fixing piece 1223, and a slider 1224.

[0047] The slide bar 1222 and the fixing piece 1223 form the bracket of the linear movement module; screws pass through the through holes of the fixing piece 1223 to fixedly arrange the bracket of the movement module inside the housing 1211. The rotating shaft 1225 is fixedly arranged on the motor 125, and the rotation of the motor 125 drives the rotation of the rotating shaft 1225. The screw 1221 is rotatably arranged on the bracket, and the motor 125 can drive the screw 1221 to rotate relative to the bracket through the rotating shaft 1225; the slider 1224 has a threaded hole in the center, the slider 1224 is sleeved on the screw 1221 through the threaded hole, the slider 1224 is threadedly connected to the screw 1221, and the slider 1224 has through holes at both ends, and the slider 1224 is sleeved on the slide bar 1222 through the through holes, so that the rotation of the screw 1221 drives the linear movement of the slider 1224.

[0048] (2) The rotation module includes a spur gear 1231, a bushing 1232, and a bracket 1233.

[0049] The bracket 1233 is fixedly arranged inside the housing 1211 through screws; the bushing 1232 is fixedly arranged on the motor 125, and the rotation of the motor 125 drives the synchronous rotation of the bushing 1232. The spur gear 1231 is rotatably arranged on the bracket 1233, the spur gear 1231 has a bushing 1232 installation cavity inside, the spur gear 1231 is sleeved and connected to the bushing 1232 through the bushing 1232 installation cavity, and incomplete teeth 12311 are formed on the outside of the spur gear 1231; asFigure 3 As shown, a shifting block 12322 is provided at the end of the bushing 1232, and the bushing 1232 is provided with a motor groove 12321 for cooperating with the transmission of the motor 125. As Figure 4 shown, a transmission block 12312 is arranged inside the installation cavity; the motor 125 rotates to drive the bushing 1232 to rotate, and the bushing 1232 drives the spur gear 1231 to rotate by squeezing the transmission block 12312 inside the bushing 1232 installation cavity of the spur gear 1231 through the shifting block 12322.

[0050] Specifically, the spur gear 1231 is sleeved outside the bushing 1232, and the motor 125 rotates to drive the bushing 1232 to rotate. When the shifting block 12322 of the bushing 1232 squeezes the transmission block 12312 of the spur gear 1231, the bushing 1232 drives the spur gear 1231 to rotate; at the same time, an idle stroke is formed between the bushing 1232 and the spur gear 1231 through the rotational spacing between the shifting block 12322 and the transmission block 12312, so that when the pressure plate is manually inserted / removed, the rotation of the spur gear 1231 is not limited by the bushing 1232.

[0051] (3) The main shaft module includes a first rotation limiting block 1241, a second rotation limiting block 1242, a magnet 1243, a limiting ring 1244, a handle spring 1245, a pin and a set screw 1246.

[0052] Both the first rotation limiting block 1241 and the second rotation limiting block 1242 are arc-shaped, and the first rotation limiting block 1241 and the second rotation limiting block 1242 are connected into an integral main shaft through a pin. The set screw 1246 is perpendicular to the axis of the pin, and it can pass through the first rotation limiting block 1241 and be threadedly connected with the pin to fix the position of the pin. Threaded holes are formed at one side end of the first rotation limiting block 1241 and the second rotation limiting block 1242, and the main shaft is threadedly connected with the thread 1131 of the handle 113 through the threaded holes, so as to realize the movement / rotation of the handle 113 to drive the integral movement / rotation of the main shaft. Incomplete teeth 12311 for cooperating with the spur gear 1231 are provided on the outer wall of the first rotation limiting block 1241. When the first rotation limiting block 1241 moves linearly along with the handle 113, the incomplete teeth on the outer wall of the first rotation limiting block 1241 and the incomplete teeth 12311 outside the spur gear 1231 always remain in a meshing state. A relief groove for cooperating with the slider 1224 is provided on the outer wall of the second rotation limiting block 1242; by providing the relief groove, when the pressure plate is manually inserted / removed, the second rotation limiting block 1242 is not limited by the slider 1224.

[0053] The limiting ring 1244 and the handle spring 1245 are sleeved on the handle 113; the limiting ring 1244 is detachably sleeved and connected with the handle 113; as Figure 5As shown in the figure, further, as a preferred embodiment of the present embodiment, a relief hole 12431 and a limiting groove 12432 are provided on the limiting ring 1244, and a limiting post 1132 is provided on the handle 113; the limiting ring 1244 is sleeved on the handle 113 through the relief hole 12431, and the limiting ring 1244 rotates by an angle so that the limiting post 1132 of the handle 113 is snapped into the limiting groove 12432, thereby realizing the detachable sleeve connection of the limiting ring 1244 on the handle 113.

[0054] The handle spring 1245 is sleeved on the handle 113. One end of the handle spring 1245 abuts against the base 114, and the other end abuts against the limiting ring 1244, providing an elastic force for the handle 113 to retract.

[0055] The magnet 1243 is arranged on the first limiting block, so that the position change of the first rotating limiting block 1241 drives the position change of the magnet 1243, and further can cooperate with the circuit control module 126 to determine the position of the handle 113.

[0056] (4) The circuit control module 126 includes a first Hall sensor 1261, a second Hall sensor 1262, a third Hall sensor 1263 and a fourth Hall sensor 1264. The first Hall sensor 1261, the second Hall sensor 1262, the third Hall sensor 1263 and the fourth Hall sensor 1264 are all installed on the circuit board. The above Hall sensors cooperate with the magnet 1243 arranged on the first rotating limiting block 1241, and the position of the handle 113 can be determined by detecting the position change of the magnet 1243.

[0057] The working principle of the remote control switch-on / off pressure plate device is described as follows:

[0058] I. Manual switch-on / off:

[0059] (1) The handle 113 is pulled out, as Figures 6-8 shown.

[0060] Manually pull the handle 113. The limiting post 1132 of the handle 113 drives the limiting ring 1244 to move synchronously, and the handle spring 1245 is compressed. At the same time, the handle 113 drives the first rotating limiting block 1241 and the second rotating limiting block 1242 to move. The magnet 1243 moves along with the first rotating limiting block 1241, and the circuit induction module senses that the electromagnetic signal switches from the first Hall sensor 1261 to the second Hall sensor 1262. Since the second rotating limiting block 1242 cooperates with the relief groove of the slider 1224, when the handle 113 is manually pulled, the second rotating limiting block 1242 is neither limited by the slider 1224 nor drives the slider 1224 to move.

[0061] (2) The handle 113 rotates 45°, as Figures 9-11 shown.

[0062] The handle 113 rotates counterclockwise by 45 degrees. The handle 113 drives the first rotation limit block 1241 and the second rotation limit block 1242 to rotate by the above angle. The magnet 1243 rotates with the first rotation limit block 1241, and the circuit induction module senses that the electromagnetic signal switches from the second Hall sensor 1262 to the third Hall sensor 1263. Through the cooperation of the arc-shaped protrusion at the bottom of the slider 1224 and the arc surface of the relief groove, the slider 1224 has a clockwise rotation limit on the second rotation limit block 1242. Therefore, the handle 113 can only rotate counterclockwise, thus avoiding incorrect rotation directions. Since the incomplete teeth 12311 of the spur gear 1231 and the incomplete teeth of the first rotation limit block 1241 always remain engaged, and there is an idle stroke between the spur gear 1231 and the bushing 1232, when the first rotation limit block 1241 drives the spur gear 1231 to rotate, the spur gear 1231 is neither limited by the bushing 1232 nor drives the bushing 1232 to rotate.

[0063] (3)The handle 113 retracts, as Figures 12-14 shown.

[0064] Release the handle 113. The handle 113 retracts under the action of the handle spring 1245, thereby driving the first rotation limit block 1241 and the second rotation limit block 1242 to retract. The magnet 1243 moves with the first rotation limit block 1241, and the circuit induction module senses that the electromagnetic signal switches from the third Hall sensor 1263 to the fourth Hall sensor 1264, and the manual insertion / withdrawal is completed.

[0065] Second, electric insertion / withdrawal:

[0066] (1)The handle 113 is pulled out, as Figures 15-17 shown.

[0067] The motor 125 drives the rotating shaft 1225 to rotate. The rotating shaft 1225 drives the screw 1221 to rotate, thereby driving the slider 1224 to move linearly. The slider 1224 drives the first rotation limit block 1241 and the second rotation limit block 1242 to move through the relief groove of the second rotation limit block 1242. The magnet 1243 moves with the first rotation limit block 1241. At this time, the circuit induction module senses that the electromagnetic signal switches from the first Hall sensor 1261 to the second Hall sensor 1262. Since the handle 113 is connected to the first rotation limit block 1241 and the second rotation limit block 1242 by threads, the handle 113 is pushed out as it moves with the first rotation limit block 1241 and the second rotation limit block 1242, and the handle spring 1245 is compressed.

[0068] (2)The handle 113 rotates 45°, as Figures 18-20 shown.

[0069] The motor 125 drives the sleeve 1232 to rotate. The block 12322 of the sleeve 1232 presses the transmission block 12312 of the spur gear 1231, thereby driving the spur gear 1231 to rotate clockwise by 45°. The spur gear 1231 drives the first limit block to rotate counterclockwise, thereby driving the handle 113 to rotate counterclockwise by the above angle. At this time, the permanent magnet 1243 rotates with the first rotation limit block 1241, and the circuit induction module senses that the electromagnetic signal switches from the second Hall sensor 1262 to the third Hall sensor 1263.

[0070] (3) The handle 113 retracts, as Figures 21-23 shown.

[0071] The motor 125 drives the rotating shaft 1225 to rotate in the reverse direction. The rotating shaft 1225 drives the screw 1221 to rotate in the reverse direction, thereby driving the slider 1224 to move linearly in the reverse direction to the initial position. The handle 113 moves to the retracted position under the elastic force of the handle spring 1245. The permanent magnet 1243 moves with the first rotation limit block 1241. At this time, the circuit induction module senses that the electromagnetic signal switches from the third Hall sensor 1263 to the fourth Hall sensor 1264. Another motor 125 drives the sleeve 1232 to rotate in the reverse direction to the initial position, and the electric insertion / withdrawal is completed.

[0072] Whether it is manual insertion / withdrawal or electric insertion / withdrawal, the sleeve 1232 and the slider 1224 are in the initial position in the final state. Therefore, the manual and electric modes can be switched arbitrarily. If the initial position of the slider 1224 is set at the bottom of the first rotation limit block 1241, the function of prohibiting manual insertion / withdrawal can be achieved.

[0073] It should be noted that the motors, circuit boards, and Hall sensors mentioned in the present invention are all prior arts and can be obtained through commercial purchase. Their internal structures, circuit wiring, and working principles are also conventional technologies. Therefore, they will not be described in detail herein.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
