[0029] The maintenance and overhaul of circuit breakers is an important part of ensuring the stable operation of the power grid. This part is related to the stability and safety of the entire power grid system, so its operation process must be accurate and correct. However, the existing maintenance and overhaul methods have some efficiency and technical problems. When the staff adjusts the opening and closing speed of the circuit breaker, a common problem is that the actual speed does not meet the standard requirements. At this time, in order to ensure that the circuit breaker can complete the opening and closing operation accurately and quickly, the adjustment of the opening and closing spring is particularly critical. The opening and closing spring is a key component that controls the action of the circuit breaker, and its elastic force directly determines the opening and closing speed of the circuit breaker. However, since these springs are designed to withstand high pressure, their elastic force is usually quite strong.

[0030] When adjusting the opening and closing speed of the circuit breaker, the staff needs to use a series of manually driven tools, such as wrenches, screwdrivers and measuring instruments, to manually adjust the spring strength inside the circuit breaker to control the opening and closing speed, especially for the opening and closing spring of the circuit breaker, which needs to be lifted and controlled by manpower.

[0031] Therefore, the workers need to spend a lot of physical strength, a lot of time, and take certain safety risks to carry out the lifting and controlling operations. In addition, this kind of work usually requires the cooperation of multiple workers, who must coordinate in order to effectively control the opening and closing springs and adjust the opening and closing speed. Therefore, the work of adjusting the opening and closing speed of the circuit breaker is highly complex and difficult.

[0032] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 , Figure 1 The invention is a structural schematic diagram of a special tool for adjusting the opening and closing speed of a circuit breaker and an assembly of the circuit breaker.

Figure 6 It is a schematic cross-sectional structural diagram of a lifting assembly of a special tool for adjusting the opening and closing speed of a circuit breaker provided in the present application.

[0034] In order to solve the above technical problems, the present application provides a special tool 1 for adjusting the speed of opening and closing of a circuit breaker, comprising a lifting assembly 2 and a driving assembly 3. The lifting assembly 2 may specifically include a push rod 21, an upper top plate 22, a first docking member 23, and a lower top plate 4. The upper top plate 22 includes an upper rotating shaft 221, and the lower top plate 4 includes a lower rotating shaft 41. The push rod 21 includes a first push rod 211, a second push rod 213, a third push rod 215, and a fourth push rod 216. The first docking member 23 may include a movable member 231, and the movable member 231 is provided with a screw hole 232. The driving assembly 3 may include a second docking member 31 and a power member. The second docking member 31 includes a screw rod 311 and a fixing member 312. The fixing member 312 can be rotatably connected to one end of the screw rod 311. The screw rod 311 is used to be screwed with the screw hole 232, and the power member drives the connection screw rod 311.

[0035] Among them, the two ends of the first push rod 211 can be rotatably connected to the upper rotating shaft 221 and the movable part 231 respectively, the two ends of the second push rod 213 can be rotatably connected to the upper rotating shaft 221 and the fixed part 312 respectively, the two ends of the third push rod 215 can be rotatably connected to the lower rotating shaft 41 and the movable part 231 respectively, and the two ends of the fourth push rod 216 can be rotatably connected to the lower rotating shaft 41 and the fixed part 312 respectively.

[0036] In the structure provided in this embodiment, the movable part 231 can move along the screw rod 311, so that the first push rod 211 and the third push rod 215 connected to the movable part 231 can rotate with the movement of the movable part 231, and since the upper rotating shaft 221 connected to the first push rod 211 is also connected to the fixed part 312 through the second push rod 213, and the lower rotating shaft 41 connected to the third push rod 215 is also connected to the fixed part 312 through the fourth push rod 216, the angle between the two adjacent push rods 21 can be changed with the movement of the movable part 231, so as to achieve the effect of changing the distance between the upper top plate 22 and the lower top plate 4, so that it can be used to abut between the circuit breaker body 6 and the opening and closing spring 7, replace the manpower assisting in the circuit breaker opening and closing speed adjustment work, and can improve the efficiency and safety of the circuit breaker opening and closing speed adjustment work.

[0037] Figure 1 , Figure 2 The circuit breaker body 6 and the opening and closing spring 7 are shown in the figure. The circuit breaker opening and closing speed adjustment special tool 1 can be pressed between the circuit breaker body 6 and the opening and closing spring 7, so that the distance between the upper top plate 22 and the lower top plate 4 can be adjusted to achieve the effect of controlling the expansion and contraction of the opening and closing spring 7. Among them, the upper top plate 22 can be used to press against the circuit breaker body 6, and the lower top plate 4 can be used to press against the opening and closing spring 7.

[0038] Before placing the special tool 1 for adjusting the opening and closing speed of the circuit breaker between the circuit breaker body 6 and the opening and closing spring 7, the screw 311 can be driven to rotate by the power part, so that the movable part 231 moves away from the fixed part 312 to reduce the distance between the upper top plate 22 and the lower top plate 4, so that the special tool 1 for adjusting the opening and closing speed of the circuit breaker can be smoothly placed between the circuit breaker body 6 and the opening and closing spring 7, so that the special tool 1 for adjusting the opening and closing speed of the circuit breaker can be pressed between the circuit breaker body 6 and the opening and closing spring 7, thereby increasing the distance between the circuit breaker body 6 and the opening and closing spring 7.

[0039] In a specific embodiment, the number of the upper rotating shaft 221 can be two. The first push rod 211 is connected to the upper rotating shaft 221 near the movable member 231, and the second push rod 213 is connected to the upper rotating shaft 221 near the fixed member 312. The first push rod 211 is provided with a first transmission tooth 212 at one end connected to the upper rotating shaft 221, and the second push rod 213 is provided with a second transmission tooth 214 at one end connected to the upper rotating shaft 221, and the first transmission tooth 212 and the second transmission tooth 214 are meshed.

[0040] Through the structure provided in this embodiment, the meshing relationship between the first transmission tooth 212 and the second transmission tooth 214 can be utilized to connect the first push rod 211 and the second push rod 213 to one end of the upper rotating shaft 221 for transmission connection, so that the first push rod 211 and the second push rod 213 can rotate synchronously when the movable part 231 moves along the screw rod 311, so that the screw rod 311 can move stably, and it is helpful to keep the extension direction of the screw rod 311 always parallel, so that the special tool 1 for adjusting the opening and closing speed of the circuit breaker can be evenly and stably extended and retracted, and can evenly apply force to the opening and closing spring 7 and the circuit breaker body 6, thereby improving the accuracy and efficiency of adjusting the opening and closing speed of the circuit breaker.

[0041] In a specific embodiment, the number of the lower rotating shaft 41 can be two, the third push rod 215 is connected to the lower rotating shaft 41 near the movable member 231, and the fourth push rod 216 is connected to the lower rotating shaft 41 near the fixed member 312. The third push rod 215 is provided with a first transmission tooth 212 at one end connected to the lower rotating shaft 41, and the fourth push rod 216 is provided with a second transmission tooth 214 at one end connected to the lower rotating shaft 41, and the first transmission tooth 212 and the second transmission tooth 214 are meshed.

[0042] Through the structure provided in this embodiment, the meshing relationship between the first transmission tooth 212 and the second transmission tooth 214 can be utilized to connect the third push rod 215 and the fourth push rod 216 to one end of the lower rotating shaft 41, so that the third push rod 215 and the fourth push rod 216 can rotate synchronously when the movable part 231 moves along the screw rod 311, so that the screw rod 311 can move stably, and it is helpful to keep the extension direction of the screw rod 311 always parallel, so that the special tool 1 for adjusting the opening and closing speed of the circuit breaker can be evenly and stably extended and retracted, and can evenly apply force to the opening and closing spring 7 and the circuit breaker body 6, thereby improving the accuracy and efficiency of adjusting the opening and closing speed of the circuit breaker.

[0043] In a specific embodiment, the first top rod 211, the second top rod 213, the third top rod 215 and the fourth top rod 216 have the same length. The first top rod 211 and the second top rod 213 can cooperate with the screw rod 311 to form an isosceles triangle structure, and the third top rod 215 and the fourth top rod 216 can cooperate with the screw rod 311 to form an isosceles triangle structure. Since the four have the same length, the line between the centers of the two isosceles triangles can be set in a direction perpendicular to the screw rod 311, thereby forming a stable diamond structure, evenly applying force to the opening and closing spring 7 and the circuit breaker body 6, thereby improving the accuracy and efficiency of adjusting the opening and closing speed of the circuit breaker.

[0044] In a specific embodiment, the circuit breaker opening and closing speed adjustment tool 1 further includes a top plate 5, which is arranged on the side of the lower top plate 4 and the upper top plate 22 away from the top rod 21. The top plate 5 can abut between the upper top plate 22 and the fulcrum, and between the lower top plate 4 and the fulcrum, so that the circuit breaker opening and closing speed adjustment tool 1 can evenly apply force to the opening and closing spring 7 and the circuit breaker body 6, thereby improving the accuracy and efficiency of adjusting the circuit breaker opening and closing speed.

[0045] Optionally, the material of the top plate 5 may specifically include manganese steel. Manganese steel is a high-strength steel material with good pressure-bearing performance, and can be used to withstand harsh working conditions such as impact, extrusion, and material wear, so that it can be used as the top plate 5 to bear the pressure brought to the circuit breaker opening and closing speed adjustment special tool 1 by the elasticity of the opening and closing spring 7.

[0046] In a specific embodiment, the circuit breaker opening and closing speed adjustment tool 1 may further include a screw 8, the top plate 5 is provided with a first hole 51, and the lower top plate 4 and the upper top plate 22 are provided with a second hole 9. The screw 8 can be inserted into the first hole 51 and the second hole 9 in sequence from the side of the top plate 5 away from the top rod 21. At least a thread is provided on the inner wall of the second hole 9, and the thread is used for screwing with the screw 8.

[0047] Through the structure provided in this embodiment, the top plate 5 can be connected to the lower top plate 4 and the upper top plate 22 by using the screws 8 inserted in the first hole 51 and the second hole 9, and the screws 8 can be screwed with the threads on the inner wall of the second hole 9, which can further limit the relative movement between the top plate 5 and the lower top plate 4 and the upper top plate 22, thereby improving the accuracy and efficiency of adjusting the opening and closing speed of the circuit breaker.

[0048] Optionally, the inner walls of the first hole 51 and the second hole 9 may be provided with threads, thereby reducing the probability of the top sheet 5 shaking relative to the lower top plate 4 and the upper top plate 22, and improving the stability of fixing the top sheet 5 to the lower top plate 4 and the upper top plate 22.

[0049] In a specific embodiment, the special tool 1 for adjusting the opening and closing speed of the circuit breaker further includes a pressure sensor, which is arranged on the surface of the side of the top plate 5 away from the top rod 21. The pressure sensor is arranged to detect the force of the top plate 5 against the top fulcrum to obtain pressure data. Due to the performance of the opening and closing spring 7, the pressure data can effectively feedback the stretching and / or compression of the opening and closing spring 7. The pressure data can be referred to by the operator, thereby improving the accuracy and efficiency of adjusting the opening and closing speed of the circuit breaker.

[0050] See also Figure 7 , Figure 7 It is a structural schematic diagram of another embodiment of the special tool for adjusting the opening and closing speed of a circuit breaker of the present application. In a specific embodiment, the special tool 1 for adjusting the opening and closing speed of a circuit breaker may further include a controller 100, the power part includes a motor 32, the controller 100 can be connected to the pressure sensor and the motor 32 respectively, and the controller 100 is used to control the rotation direction of the motor 32.

[0051] Through the structure of the special tool 1 for adjusting the opening and closing speed of a circuit breaker provided in this specific embodiment, the controller 100 can be used to obtain the pressure data measured by the pressure sensor, so that the controller 100 can control the operation of the motor 32 based on the feedback of the pressure data, and then adjust the working condition of the motor 32 based on the feedback, thereby improving the accuracy of the controller 100 in controlling the operation of the motor 32, making the special tool 1 for adjusting the opening and closing speed of the circuit breaker more accurate during the jacking operation, and improving the usability of the special tool 1 for adjusting the opening and closing speed of the circuit breaker.

[0052] Specifically, the controller 100 may include a lifting button 101 and a retracting button 102, which are respectively used to control the motor 32 to rotate in opposite directions, thereby driving the screw 311 to rotate in two different directions, and can adjust the distance between the upper top plate 22 and the lower top plate 4.

[0053] Optionally, the controller 100 may also be configured with a human-machine interaction interface, and the operator may obtain the pressure data measured by the pressure sensor through the human-machine interaction interface. For example, the human-machine interaction interface includes a display screen, and the controller 100 displays the pressure data on the display screen, and the operator may visually view the pressure data through the display screen.

[0054] In a specific embodiment, the circuit breaker opening and closing speed adjustment tool 1 may further include a communication component, which can be connected to the controller 100 and is used to establish a signal connection with a client device.

[0055] Through the structure provided in this specific embodiment, a signal connection can be established with the client device by using the communication component, so that the operator of the circuit breaker opening and closing speed adjustment special tool 1 can use the client device to transmit instructions to the controller 100, and can obtain the pressure data measured by the pressure sensor from the controller 100. This is conducive to the operator to remotely control the motor 32 according to the pressure data, and achieve the effect of remotely controlling the circuit breaker opening and closing speed adjustment special tool 1.

Among them, wireless communication technology is a communication method that uses the characteristics of electromagnetic wave signals that can propagate in free space to exchange information, and can include at least one of 4G (fourth generation mobile communication technology), ZigBee technology, WLAN (wireless local area network), WiFi (Wireless Fideliry, wireless broadband technology), WAPI (WLAN Authentication and Privacy Infrastructure), Bluetooth technology (Bluetooth), RFID (Radio Frequency Identification Technology), and IrDA (infrared point-to-point communication technology). Wired communication technology can include at least one of Ethernet protocol (Ethernet), TCP / IP protocol (Transmission Control Protocol / Internet Protocol, transmission control protocol / Internet protocol), USB (Universal Serial Bus) protocol, HDMI protocol (a high-definition multimedia interface transmission protocol), and RS-232C protocol (a serial communication protocol standard).

[0057] In order to solve the above technical problems, the present application also provides a control method of a special tool 1 for adjusting the opening and closing speed of a circuit breaker, which is implemented by using the special tool 1 for adjusting the opening and closing speed of a circuit breaker as described in any one of the above specific embodiments.

It should be noted that if there is substantially the same result, this embodiment is not based on Figure 8 The process sequence shown is limited.
