Description

Technical Field

[0001] The invention relates to the technical field of transformer substation isolating switches, and more particularly to a one-button sequential control isolating switch double confirmation device. Background Art

[0002] One-button sequential control is one of the advanced applications of smart substations. It is a key technology to promote the deep integration of modern information technology and power grid technology and build an intelligent operation and inspection system. With the introduction of the concept of a new generation of power systems, primary equipment will face the situation of how to adapt to the new requirements of the secondary system. As an important technology to support the construction of a new generation of power systems, the one-button sequential control function of the disconnector needs to introduce "double confirmation" measures to ensure the accuracy of operation and the safety of equipment, and realize the transformation of the traditional cumbersome, repetitive, and error-prone switching operation mode based on manual filling of operation tickets into a remote one-button sequential control operation mode.

[0003] However, the signal double confirmation device in the current one-touch sequential switch, when involving double confirmation of multiple signals, usually sets multiple cams on a rotating shaft, and each cam touches the corresponding signal switch to achieve double confirmation. For example, when there are three signals A, B, and C in the equipment that need double confirmation, three cams are set on the rotating shaft. When the equipment outputs signal A, the cam corresponding to signal A also happens to touch the corresponding signal switch to achieve double confirmation. This method takes up too much space. As the number of signals that need to be confirmed increases, the length of the rotating shaft and the volume of the overall device will increase significantly, which is not conducive to the compact layout and maintenance of the equipment;

[0004] Another method is to use only one cam to contact multiple signal switches around it. This method requires the installation of a processor to solve the problem of repeated touch during rotation. It not only increases the complexity and cost of the system, but also increases the risk of processor errors, affecting the stability and reliability of the system. Summary of the invention

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] A one-button sequential control isolating switch double confirmation device comprises a base plate, a gear set is arranged on the base plate, the gear set comprises a plurality of gears, one of the gears is connected to the output shaft of the equipment to realize rotation and drives the other gears to rotate, a plurality of signal switches are arranged on the base plate, and the plurality of gears respectively trigger one of the signal switches.

[0007] The present invention is further configured as follows: an abutment block is provided on the gear, the abutment block protrudes to the outside of the gear, and a trigger button is provided on the side of the signal switch facing its corresponding gear. When the gear rotates, the abutment block touches the trigger button to trigger the signal switch.

[0008] The present invention is further configured as follows: a threaded hole is provided on the top of the gear, a long slot is provided on the abutment block, and a bolt passes through the long slot and is threadedly connected to the threaded hole, thereby fixing the abutment block on the gear.

[0009] The present invention is further configured as follows: at least two threaded holes are provided on the gear, and long grooves corresponding to the threaded holes are provided on the abutment block.

[0010] The present invention is further configured as follows: a plurality of the gears are meshed in sequence, the gear set comprises a driving gear and a plurality of driven gears, the driving gear is connected to the output shaft of the equipment to realize rotation, and drives the driven gears to rotate.

[0011] The present invention is further configured such that: the driving gear is located at the end of the gear set, and the rotating axes of the gear set are connected to form a straight line.

[0012] The present invention is further configured as follows: the modules of the driving gear and the driven gear are both 0.5, the number of teeth of the driving gear is 65, and the number of teeth of the driven gear is 130.

[0013] The present invention is further configured as follows: a plurality of the signal switches correspond one-to-one to the gears, the signal switches corresponding to the driving gear are located on a side of the driving gear away from the driven gear, and the signal switches corresponding to the driven gear are arranged on both sides or on the same side of a straight line formed by the rotating shafts of the gear set.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. By setting a gear set and a number of signal switches, the output shaft of the equipment drives one of the gears to rotate, and indirectly drives the other gears to rotate. Each gear corresponds to a signal switch. During the rotation process, the gear will trigger the signal switch and the signal in the equipment for double confirmation. Several gears realize the double confirmation of multiple signals. The gear set is set on the same horizontal plane, which will not increase the thickness of the device, save space, make the equipment layout more compact, and adopt a pure mechanical structure without the need for additional processors, with high accuracy and strong stability.

[0016] 2. The abutment block is fixed by opening a long groove and cooperating with bolts, so that the distance of the abutment block protruding from the gear can be adjusted. It can be adjusted according to different types of trigger buttons, and can also be adjusted when there is a processing error. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] A one-button sequential control isolating switch double confirmation device, such as Figure 1 and Figure 2 As shown, it includes a base plate 1, on which a gear set 2 is arranged. The gear set 2 includes a plurality of gears, which are all located in the same plane and have the same thickness. One of the gears is connected to the output shaft of the device. The rotation of the output shaft of the device drives it to rotate synchronously, and indirectly drives the remaining gears to rotate. A plurality of signal switches 3 are arranged on the base plate 1. The plurality of gears trigger a signal switch 3 respectively. The signal switches 3 correspond to the signals in the device for double confirmation.

[0025] An abutment block 4 is fixed on the gear, and the abutment block 4 protrudes to the outside of the gear. The abutment block 4 rotates synchronously with the gear. A trigger button 301 is provided on the side of the signal switch 3 facing its corresponding gear. The trigger button 301 is a part of the signal switch 3. When the gear rotates until the abutment block 4 faces the signal switch 3, the abutment block 4 presses the trigger button 301 to trigger the signal switch 3.

[0026] like Figure 3As shown, a threaded hole 5 is provided on the top of the gear, and a long slot 6 is provided on the abutment block 4. A bolt passes through the long slot 6 and is threadedly connected to the threaded hole 5. The head of the bolt abuts against the abutment block 4, thereby fixing the abutment block 4 on the gear. The long slot 6 is extended radially along the gear, so that the abutment block 4 can adjust the installation position, thereby adjusting the length of the abutment block 4 protruding from the outside of the gear, so that the abutment block 4 can fit exactly with the trigger switch.

[0027] At least two threaded holes 5 are provided on the top of the gear. By providing at least two threaded holes 5, the abutment block 4 can be prevented from rotating and deviating. In this embodiment, two threaded holes 5 are provided, and two long grooves 6 are also provided on the abutment block 4. The two long grooves 6 correspond to the threaded holes 5 one by one.

[0028] In this embodiment, the gear set 2 is configured as a plurality of gears meshing in sequence, and the gear is a gear plate. The gear set 2 includes a driving gear 201 and a plurality of driven gears 202. The driving gear 201 is connected to the output shaft of the device to realize rotation, and drives the driven gear 202 to rotate. Specifically, two driven gears 202 are provided. The driving gear 201 drives the first driven gear 202 to rotate, and the first gear drives the second gear to rotate. Three rotating shafts are vertically arranged on the bottom plate 1. The driving gear 201 and the driven gear 202 are respectively sleeved on the rotating shaft. The inner side of the gear is connected to the rotating shaft through a spline, thereby driving the gear to rotate. The rotating shaft of the driving gear 201 is fixedly connected to the output shaft of the device. The output shaft of the device directly drives the driving gear 201 to rotate through the rotating shaft. The driving gear 201 is located at the end of the gear set 2, and the rotating shafts of the plurality of gears are connected in a straight line.

[0029] like Figure 1 and Figure 2 As shown, a top cover 8 is also provided on the bottom plate 1, and a plurality of connecting columns protrude from the bottom plate 1. The connecting columns are higher than the abutment blocks 4. Bolts pass through the top cover 8 and are threadedly connected to the connecting columns, thereby fixing the top cover 8 on the bottom plate 1. The top cover 8 covers the gear set 2. A plurality of notches are provided on the top cover 8, and the notches make way for the signal switch 3. A plurality of thread grooves are provided on the bottom plate 1. The signal switch 3 passes through the bottom plate 1 by bolts, and each signal switch 3 corresponds to two thread grooves.

[0030] Several signal switches 3 correspond to gears one by one. The signal switch 3 corresponding to the driving gear 201 is located on the side of the driving gear 201 away from the adjacent gear. The signal switches 3 corresponding to the other gears are arranged on both sides or on the same side of a straight line connecting the rotating shafts of the several gears. In this embodiment, the signal switches 3 corresponding to the driven gear 202 are all located on the same side.

[0031] The initial position of the abutment block 4 on the gear can be different according to the time of signal triggering in the device. By setting the corresponding module and gear, the gears can be transmitted in sequence, and the time when the abutment block 4 on the gear triggers the signal switch 3 is synchronized with the signal triggering time in the device, so as to perform double confirmation. In this embodiment, the module of the driving gear 201 and the driven gear 202 are both 0.5, the number of teeth of the driving gear 201 is 65, and the number of teeth of the driven gear 202 is 130, which can meet the double confirmation of the device signal in this embodiment.

[0032] The bottom plate 1 can be provided with a positioning hole 7 to assist in positioning the initial position of the gear. Usually, a positioning column is inserted into the positioning hole 7 to block and position the abutment block 4. The positioning column needs to be removed when in use.

[0033] The working process of the present invention is as follows:

[0034] Signals A, B, and C in the device correspond to the active gear 201, the first driven gear, and the second driven gear respectively. The output shaft of the device directly drives the active gear 201 to rotate. When the device triggers signal A, the abutment block 4 on the active gear 201 just rotates to the key switch, and the signal A is double-confirmed. When the device triggers signal B, the abutment block 4 on the first driven gear just rotates to the key switch, and the signal B is double-confirmed. When the device triggers signal C, the abutment block 4 on the second driven gear just rotates to the key switch, and the signal C is double-confirmed.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
