After the second energy storage element releases energy to drive the switch to open, the above structure can still be closed by operating the operating mechanism. There is a possibility of uninformed mistaken closing, which poses a safety hazard.

[0003] The padlock structure currently designed for the rotary isolating switch, such as disclosed in the applicant's prior patent CN201920130016.2, is usually a mechanical padlock structure for the knob, which cannot be remotely controlled and cannot be processed in time. Utility Model Content

[0006] It also includes a padlock mechanism, which includes a second drive mechanism. The second drive mechanism is provided with a second port for receiving a control signal. The second drive mechanism cooperates with the operating mechanism. When the second drive mechanism receives the control signal, the second drive mechanism is actuated to prevent the operating mechanism in the open state from switching to the closed state.

[0008] The first energy storage element is an energy storage torsion spring, which includes a first torsion arm and a second torsion arm.

[0010] It also includes an energy storage mechanism, which has an energy storage state and an energy release state. When the energy storage mechanism is in the energy storage state, the operating mechanism can normally switch between the closed state and the open state.

The second energy storage element is a torsion spring sleeved on the second operating shaft and its two ends are respectively matched with the inner wall of the housing and the rack. The energy storage lock block is used to form a locking effect on the second energy storage element in the energy storage state. The second operating shaft has a gear structure meshing with the rack. When the energy storage lock block moves to release the locking effect on the second energy storage element in the energy storage state, the second energy storage element in the energy storage state releases energy to push the rack, so that the second operating shaft and the first energy storage element rotate to open the gate;

[0013] A connecting rod is provided between the second driving mechanism and the energy storage lock block, and the second driving mechanism drives the energy storage lock block to move through the connecting rod to release the locking effect on the second energy storage element in the energy storage state.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0036] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0037] The directions and positions mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only directions or positions with reference to the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0038] A remotely lockable rotary isolating switch, such as Figure 1-Figure 5As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, and a first driving mechanism 400 arranged in the housing assembly 100. The housing assembly 100 includes an upper housing 120, a middle housing 130, and a lower housing 140 arranged in sequence from top to bottom, wherein an upper cavity is formed between the upper housing and the middle housing 130, and a lower cavity is formed between the middle housing 130 and the lower housing 140, and the middle housing 130 has a middle partition separating the upper cavity and the lower cavity, wherein the operating mechanism is arranged in the lower cavity, and the energy storage mechanism is arranged in the upper cavity.

[0039] Specifically, the operating mechanism includes a stopper, a first operating shaft 210, a first energy storage element 220, and an operating swivel seat 230, which are arranged in sequence. The first operating shaft 210 and the operating swivel seat 230 are arranged concentrically. The first energy storage element 220 is arranged between the first operating shaft 210 and the operating swivel seat 230, and the two ends of the first operating shaft 210 and the operating swivel seat 230 are respectively abutted and matched. The center of the stopper abuts against the middle shell 130 and cannot rotate relative to the middle shell 130. Figure 3 As shown, the stopper protrudes toward the operating swivel seat 230 to form a first steering limit elastic block 241 and a second steering limit elastic block 242. Figure 6 As shown, the operating seat 230 protrudes toward the stopper to form a first limit block 231 and a second limit block 232. When the operating mechanism is located at the closing / opening position, the first steering limit elastic block 241 and the second steering limit elastic block 242 are respectively located on both sides of the first limit block 231 / the second limit block 232. Figure 4 As shown, the first operating shaft 210 is provided with an unlocking push block 211 for lifting the first steering limit elastic block 241. When the first operating shaft 210 is turned from closing to opening / opening to closing, the unlocking push block 211 can lift the first steering limit elastic block 241 and the second steering limit elastic block 242. The operating rotating seat 230 is used to cooperate with the moving contact of the switch unit coaxially, and the rotation of the operating rotating seat 230 can simultaneously drive the moving contact to rotate to complete the switching action.

[0040] The inner wall of the housing assembly 100 is provided with a linkage block, such as Figure 3As shown, the stopper is provided with a linkage groove 245 that cooperates with the linkage block. The first steering limit block 241 and the second steering limit block 242 are respectively protrusions formed by the ends of two relatively separated support arms with a certain elasticity on the periphery of the stopper. At the same time, the lower surfaces of the two relatively separated support arms on the periphery of the stopper are respectively provided with a first unlocking push protrusion 243 and a second unlocking push protrusion 244 that cooperate with the unlocking push block 211. When the unlocking push block 211 slides to the position below the first unlocking push protrusion 243 or the second unlocking push protrusion 244, the corresponding first steering limit block 241 or the second steering limit block 242 is lifted accordingly. Figure 4 As shown, the first operating shaft 210 is provided with a positioning column 212 for coaxially positioning with the operating rotating seat 230, a first driving arm 213 for cooperating with the torsion arm of the first energy storage element 220, and an unlocking push block 211 for raising the first unlocking push protrusion 243 and the second unlocking push protrusion 244. Figure 5 As shown, the first energy storage element 220 is an energy storage torsion spring, which includes a first torsion arm 221 and a second torsion arm 222; Figure 6 As shown, the operating swivel seat 230 is provided with an upwardly protruding first limit block 231 , a second limit block 232 , a second driving arm 233 for cooperating with the second torque arm 222 of the first energy storage element 220 , and a positioning annular seat 234 coaxially plugged and positioned with the positioning column 212 .

[0041] In the process of the first operating shaft 210 turning from opening to closing, first, the first driving arm 213 of the first operating shaft 210 drives the first torque arm 221 to rotate, and the first energy storage element 220 starts to store energy. During the rotation process, the unlocking push block 211 cooperates with the stopper. When the first operating shaft 210 is close to being rotated to the closing position, the unlocking push block 211 rotates to a position below the first unlocking push protrusion 243, so that the first steering limit block 241 is lifted. At this time, the operating seat 230 is free and rotates to the closing state under the drive of the second torque arm 222. The opening process is reverse, that is, the first driving arm 213 of the first operating shaft 210 drives the second torque arm 222 to rotate, the first energy storage element 220 starts to store energy, and the operating seat 230 does not rotate. When the first operating shaft 210 is close to being rotated to the opening position, the unlocking push block 211 is unlocked to free the operating seat 230 and rotates to the opening position under the drive of the first torque arm 221.

[0042] Specifically, the energy storage mechanism includes a second energy storage element, a second operating shaft 310, a rack 320, and an energy storage lock block 330. The second operating shaft 310 is coaxially plugged with the first operating shaft 210 and the two are circumferentially linked. At the same time, the second operating shaft 310 passes through the shell to be connected with a manual operating handle or an electric operating mechanism to achieve the opening and closing operation. The second energy storage element is a torsion spring sleeved on the second operating shaft 310 and its two ends are respectively matched with the inner wall of the shell and the rack 320. The energy storage lock block 330 is used to lock the second energy storage element in the energy storage state. The second operating shaft 310 has a gear structure meshing with the rack 320. When the energy storage lock block 330 moves to release the locking effect on the second energy storage element in the energy storage state, the second energy storage element in the energy storage state releases energy to push the rack 320, so that the second operating shaft 310 and the first energy storage element 220 rotate to achieve opening and power off. The specific matching structure between the second energy storage element, the second operating shaft 310, the rack 320, and the energy storage lock block 330 is not elaborated here. For details, please refer to the relevant structure recorded in the patent CN202321023758.8 specification.

[0043] The first driving mechanism 400 is an electromagnetic driving mechanism, and is provided with a first port 410 for receiving a control signal. The control signal can cause the first driving mechanism 400 to actuate the energy storage lock block 330. Specifically, a connecting rod 500 is provided between the first driving mechanism 400 and the energy storage lock block 330. Fig.11 As shown, the connecting rod 500 is provided with a first hinged portion 510 for being hingedly connected to the housing assembly 100, a first pushing portion 520 arranged corresponding to the first driving mechanism 400, and a driving portion 530 arranged corresponding to the energy storage lock block 330. The first driving mechanism 400 drives the energy storage lock block 330 to move to a position to release the locking effect on the second energy storage element in the energy storage state through the transmission of the connecting rod 500, and the energy storage mechanism releases energy to achieve opening and power off.

[0044] Specifically, Fig. 9 As shown, a first hinge seat 143 for mounting the first hinge part 510 is provided on the lower shell 140 .

[0045] At the same time, a reset transmission member 600 is provided between the first drive mechanism 400 and the second operating shaft 310 to reset the first drive mechanism 400, that is, by rotating the second operating shaft 310 from the opening position to the closing position, the first drive mechanism 400 can be reset, the second energy storage element can be stored, and the switch unit can be closed. The specific structure of the reset transmission member 600 can refer to the relevant structure recorded in the patent CN202111031928.2 specification, which will not be elaborated here.

[0046] After a fault occurs, a control signal is sent to the first drive mechanism 400 to release the energy of the second energy storage element, thereby quickly opening the switch and shutting off the power. After the fault is eliminated, the second operating shaft 310 is rotated to close the switch and reset the second energy storage element and the first drive mechanism 400.

[0047] In this embodiment, on the basis of the above structure, a padlock mechanism is added in the housing assembly 100, through which the switch cannot be closed and reset, avoiding misoperation. When the fault is not eliminated and solved, the switch is closed and energized. Specifically, the padlock mechanism includes a second drive mechanism 700, which is provided with a second port 710 for receiving a control signal. The second drive mechanism 700 cooperates with the operating mechanism. When the second drive mechanism 700 receives the control signal, it acts to prevent the operating mechanism from rotating from the open position to the closed position, avoiding misoperation after a major fault occurs.

[0048] Specifically, Figure 2 As shown, a swing rod 800 is provided between the second driving mechanism 700 and the first energy storage element 220. When the second driving mechanism 700 is actuated, the swing rod 800 cooperates with the first energy storage element 220 in the off state, so that the first energy storage element 220 cannot be actuated.

[0049] like Figure 8 As shown, the middle part of the swing lever 800 is provided with a second hinged portion 810 hingedly matched with the housing assembly 100, a third pushing portion 820 corresponding to the second driving mechanism 700, and a locking portion 830 corresponding to the first energy storage element 220. When the second driving mechanism 700 is actuated, the locking portion 830 locks the first energy storage element 220 located in the opening position, making it unable to move, thereby making the entire operating mechanism unable to perform the closing action, thereby forming a padlock function.

[0050] Specifically, Figure 8 As shown, the locking portion 830 is hook-shaped, forming a limit groove 831 with an opening at the lower end, and a first action spring 840 is provided to act on the swing rod 800 to keep the locking portion 830 away from the first energy storage element 220 without interfering with its normal operation. When the second driving mechanism 700 receives a control signal to make it operate, as shown in FIG. Figure 2 As shown, the second driving mechanism 700 drives the third pushing portion 820, and the locking portion 830 moves downward, so that the first torsion arm 221 of the first energy storage element 220 enters the limiting groove 831 from the lower end opening of the limiting groove 831, so that the first torsion arm 221 of the first energy storage element 220 cannot perform the closing action, thereby locking the first energy storage element 220 and operating the rotating seat 230.

[0051] Specifically, Fig. 9As shown, the lower shell 140 is provided with a second hinge seat 141 for mounting the second hinge part 810 and a spring limiting groove 142 for mounting the first action spring 840 .

[0052] Furthermore, the second driving mechanism 700 of the present embodiment includes an electromagnetic coil fixing member 720 and an electromagnetic driving block 730 to which an electromagnetic coil is fixed, and a second action spring 740 is provided between the electromagnetic coil fixing member 720 and the electromagnetic driving block 730. In the present embodiment, the electromagnetic coil fixing member 720 is a shell made of a magnetically conductive material such as low carbon steel, electrical pure iron, etc., the electromagnetic coil is fixed in the shell, and the electromagnetic driving block 730 is at least partially made of a permanent magnet; there is an adsorption force and an absorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730. The attachment force is greater than the thrust of the second action spring 740 after energy storage, ensuring that the shell made of magnetic conductive material and the electromagnetic drive block 730 maintain an adsorption relationship in the initial state; when the second drive mechanism 700 receives the padlock control signal, the electromagnetic coil is energized to form a magnetic field and the direction of the magnetic field forms a repulsive force away from the electromagnetic coil on the electromagnetic drive block 730, and the sum of the repulsive force and the thrust of the second action spring 740 after energy storage is greater than the attachment force between the shell made of magnetic conductive material and the electromagnetic drive block 730, so that the electromagnetic drive block 730 can be pushed to move.

[0053] Furthermore, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700, specifically, Figure 1 , Figure 2 As shown, a push rod 750 is provided below the electromagnetic driving block 730 of the second driving mechanism 700 , and the push rod 750 passes through the housing assembly 100 . By pressing the push rod 750 , the electromagnetic driving block 730 can be reset and re-adsorbed onto the electromagnetic coil fixing member 720 .

[0054] Furthermore, the connecting rod 500 of this embodiment is further provided with a second pushing portion 540 corresponding to the second driving mechanism 700. Fig.10 As shown, the second driving mechanism 700 moves to push the second pushing portion 540, and drives the energy storage lock block 330 to move to a position to release the locking effect on the second energy storage element in the energy storage state through the transmission of the connecting rod 500.

[0055] In this embodiment, the first drive mechanism 400 and the second drive mechanism 700 can both release the energy of the energy storage mechanism, thereby realizing the opening and power off. Only the first drive mechanism 400 is in motion, and the closing and energy storage mechanism energy storage reset can be realized by turning the knob to close the switch. Only the second drive mechanism 700 is in motion, and the closing and energy storage mechanism energy storage reset cannot be realized by turning the knob to close the switch. The second drive mechanism 700 must be manually pushed to reset by the push rod 750 before the closing and energy storage mechanism energy storage reset can be realized by turning the knob to close the switch. When this embodiment is used, the first drive mechanism 400 or the second drive mechanism 700 can be selected to act according to the severity of the fault, or the first drive mechanism 400 and the second drive mechanism 700 can act synchronously, or the first drive mechanism 400 can act and the second drive mechanism 700 can be controlled by remote signals. The first drive mechanism 400 and the second drive mechanism 700 can be automatically actuated by different fault signals, or the first drive mechanism 400 and the second drive mechanism 700 can be manually actuated by remotely sending control signals based on the fault situation.

[0056] A person skilled in the art can understand that all or part of the steps in the above-mentioned embodiment method can be completed by instructing related hardware through a program, and the program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, CD-ROM, etc.

[0057] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
