[0085] In order to clearly describe the technical solutions of the embodiments of the present application, the following briefly introduces some terms and technologies involved in the embodiments of the present application:

[0086] Converter module: an electronic device that converts direct current into alternating current, widely used in photovoltaic power generation, wind power generation, electric vehicles, uninterruptible power supplies and industrial automation, etc. to achieve efficient conversion and control of electric energy.

[0092] Sprocket: a mechanical element with a toothed rim, designed specifically for meshing with a chain to transmit power, widely used in industrial machinery and conveying systems to achieve power transmission and motion control.

[0093] The exemplary embodiments will be described in detail in this paper, and the examples are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0094] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0095] In order to clearly understand the technical solutions of the present application, the prior art solutions will be described in detail first. In the prior art, the converter module is installed in the control cabinet, and the converter module and the control cabinet are connected by screws. When replacing the converter module, the maintenance personnel will first remove the fixing screws of the converter module, disconnect the mechanical connection between the converter module and the control cabinet, and move the converter module away. Then, the new converter module is moved into the control cabinet, and the converter module and the control cabinet are connected by screws.

[0096] Currently, during the replacement of the converter module, the converter module is usually disassembled and assembled by manually disassembling and assembling the screws, and the converter module is moved by manual carrying. Although this replacement method can install the converter module in the control cabinet, it also brings some problems. Each time the converter module is replaced, manual screw installation may cause the screws to be not completely tightened or position offset. For example, if the screws are not tightened in place, they may loosen during equipment operation, causing poor module contact or falling off. In addition, position offset may cause uneven gaps between the module and other components, affecting heat dissipation, increasing the risk of module overheating, and thus shortening the service life of the equipment. Therefore, manual screw installation may affect the stability of the replacement of the converter module. At the same time, the converter module is usually heavy, and when replacing the converter module at a high place, if the converter module falls from a high place, it will affect the safety of the maintenance personnel and the converter module. Therefore, the current replacement of the converter module has the problems of low stability and low safety.

[0097] Therefore, in order to solve the problem of low stability and low safety in the replacement of the converter module in the prior art, it is found in the research that in order to solve the problem, a converter module replacement device which can flexibly move the converter module and firmly install the screws needs to be designed: ①During the replacement of the converter module, the converter module needs to move up and down and also needs to move forward and backward, so a moving guide rail and a moving assembly can be arranged on the converter module replacement device. ②In order to ensure that the screws are firmly installed, an electric wrench can be arranged on the converter module replacement device to disassemble and assemble the screws using the electric wrench.

[0098] Specifically,

[0099] A jack can be used to move the converter module up and down, a moving guide rail is connected to the jack, and the moving guide rail is used to move the converter module forward and backward. At the same time, an electric wrench is arranged on the moving guide rail to disassemble and assemble the screws using the electric wrench.

[0100] The converter module replacement device of the embodiment of the present application moves the converter module up and down through the lifter, moves the converter module forward and backward through the moving plate, avoids the safety problems caused by manual carrying, and improves the safety of the replacement of the converter module. The electric wrench head is used to install the screws on the converter module, which avoids the problems of incomplete tightening or position offset of the screws caused by manual screw installation, and improves the stability of the replacement of the converter module.

[0101] Based on the above creative findings, the technical scheme of the present application is proposed.

[0102] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0103] Figure 1Schematic diagram of the converter module replacement device provided in the embodiments of this application Figure One .like Figure 1 As shown, in this embodiment, the converter module replacement device includes: a base 100, a lifter 200, a first bracket 300, a second bracket 400, a lifting platform 500, a moving plate 600, an electric wrench assembly 700, a double-ended screw 800, a lead screw 900, and a motor 1000.

[0104] Specifically, the base 100 provides the basic support structure for the entire device, ensuring its stability and fixation, and allowing other components to be securely installed and operated. The lifter 200 drives the lifting platform 500 to move up and down, enabling the converter module to be disassembled and installed at different heights, providing vertical movement capability. One end of the first bracket 300 is connected to the base 100, ensuring the vertical stability of the lifter 200 and the lifting platform 500. The second bracket 400 is parallel to the first bracket 300 and also connected to the base 100, providing additional stability and support. The lifting platform 500 carries the moving plate 600 and the converter module, and moves up and down under the drive of the lifter 200 to adjust the position of the converter module. The moving plate 600 is slidably connected to the lifting platform 500, used to move the converter module on a horizontal plane, achieving horizontal displacement through the drive of the lead screw 900, facilitating module disassembly and installation. The electric wrench assembly 700 is used for removing and installing screws on the converter module. It includes an electric wrench head 7001, a forward button 7002, and a reverse button 7003, providing automated screw operation. The double-ended screw 800 connects the moving plate 600 and the electric wrench assembly 700, ensuring that the electric wrench assembly 700 moves with the moving plate 600, thereby enabling operation of the converter module. The lead screw 900, driven by the motor 1000, rotates the moving plate 600 horizontally, allowing the converter module to move closer to or away from the control cabinet. The motor 1000 drives the lead screw 900 to rotate, thereby achieving the horizontal movement of the moving plate 600, providing the power source, and controlling the horizontal displacement of the converter module.

[0105] One end of the first bracket 300 and one end of the second bracket 400 are both connected to the top of the base 100, and the first bracket 300 and the second bracket 400 are parallel.

[0106] Specifically, welding or other mechanical connection methods can be used to connect one end of the first support 300 and the second support 400 to the top of the base 100. Through this connection method, a stable frame structure is formed, ensuring that the lifter 200, the lifting platform 500, and other components can maintain balance and stability during operation. The parallel first support 300 and second support 400 also ensure smooth movement of the lifting platform 500 in the vertical direction, avoiding tilting or shaking, thereby improving the reliability and safety of the entire device.

[0107] One end of the lifter 200 is connected to the top of the base 100, and the other end is connected to the lifting platform 500. The lifter 200 is arranged between the first support 300 and the second support 400 and is used to drive the lifting platform 500 to move up and down.

[0108] Specifically, bolt fixation or other mechanical connection methods can be used to ensure that the lifter 200 is firmly fixed to the base 100. The other end of the lifter 200 is connected to the lifting platform 500 through a similar connection method. One end of the lifter 200 is connected to the top of the base 100, and the other end is connected to the lifting platform 500, providing vertical movement capability. Through the driving of the lifter 200, the lifting platform 500 can smoothly move up and down in the vertical direction, thereby adjusting the position of the converter module. This design ensures that the converter module can be disassembled and installed at different heights, improving the flexibility and adaptability of the device.

[0109] The moving plate 600 is slidingly connected to the lifting platform 500.

[0110] Specifically, a guide rail and slider design can be used to achieve the sliding connection between the moving plate 600 and the lifting platform 500. A guide rail is installed on the lifting platform 500, and a slider matching the guide rail is installed at the bottom of the moving plate 600. In this way, the moving plate 600 can smoothly slide along the guide rail on the lifting platform 500. The sliding connection between the moving plate 600 and the lifting platform 500 is used to achieve the movement of the converter module in the horizontal plane. This design ensures smooth movement of the converter module during disassembly and installation, avoiding damage to the module due to poor movement.

[0111] The moving plate 600 is provided with a connecting hole, and the lead screw 900 is connected to the moving plate 600 through the connecting hole. One end of the lead screw 900 is connected to the motor 1000, and the motor 1000 is used to drive the lead screw 900 to rotate.

[0112] Specifically, a connecting hole can be pre-machined on the moving plate 600, ensuring that the size and position of the hole match the lead screw 900. Then, the lead screw 900 is inserted through the connecting hole on the moving plate 600, allowing the lead screw 900 to rotate freely but not to move axially. One end of the lead screw 900 is connected to the output shaft of the motor 1000 through a coupling or other connection method, ensuring that the motor 1000 can effectively drive the lead screw 900 to rotate. After the lead screw 900 is connected to the moving plate 600 through the connecting hole, it rotates under the drive of the motor 1000. The motor 1000 drives the lead screw 900 to rotate, thereby driving the moving plate 600 to move in the horizontal plane through the screw drive of the lead screw 900. This design is used to realize the movement of the converter module in the horizontal plane, so that the module can approach or move away from the control cabinet, facilitating the disassembly and installation operation of the module.

[0113] One end of the double-headed screw 800 is connected to the moving plate 600, and the other end of the double-headed screw 800 is connected to the electric wrench assembly 700.

[0114] Specifically, to realize the connection of one end of the double-headed screw 800 to the moving plate 600, a threaded hole can be pre-provided on the moving plate 600 or a nut can be used to fix one end of the double-headed screw 800. By screwing one end of the double-headed screw 800 into the threaded hole of the moving plate 600 or by fixing it with a nut, the double-headed screw 800 is firmly connected to the moving plate 600. The other end of the double-headed screw 800 is connected to the electric wrench assembly 700 in a similar manner. One end of the double-headed screw 800 is connected to the moving plate 600, and the other end is connected to the electric wrench assembly 700, which is used to drive the electric wrench assembly 700 to move synchronously when the moving plate 600 moves horizontally. This design can ensure that the electric wrench assembly 700 can move with the moving plate 600, improving the precision and efficiency of the operation and avoiding operation errors caused by position deviation.

[0115] The electric wrench assembly 700 is provided with an electric wrench head 7001, a forward rotation button 7002, and a reverse rotation button 7003, and is used to disassemble and install the converter module.

[0116] Specifically, the electric wrench head 7001 can be installed on the electric wrench assembly 700 through a mechanical connection method to facilitate the disassembly and installation of screws of different specifications. The electric wrench assembly 700 is provided with the electric wrench head 7001, the forward rotation button 7002 and the reverse rotation button 7003 for realizing the automated disassembly and installation of the converter module. The electric wrench head 7001 is used to cooperate with the screws on the converter module, the forward rotation button 7002 is used to control the clockwise rotation of the electric wrench head 7001 to tighten the screws, and the reverse rotation button 7003 is used to control the counterclockwise rotation of the electric wrench head 7001 to loosen the screws. This design simplifies the disassembly and installation process of the converter module, improves the operation efficiency and accuracy, and reduces the error of manual operation.

[0117] When disassembling the converter module, the forward rotation button 7002 is used to make the electric wrench head 7001 rotate forward, the electric wrench head 7001 is used to disassemble the screws on the converter module, the electric wrench head 7001 is also used to connect with the converter module after the screws are disassembled, the motor 1000 is used to drive the lead screw 900 to rotate reversely, the lead screw 900 is used to drive the moving plate 600, the electric wrench assembly 700 and the converter module to move away from the control cabinet, and the lifter 200 is used to drive the lifting platform 500 to move downward.

[0118] When installing the converter module, the lifter 200 is used to drive the lifting platform 500 to move upward, the motor 1000 is used to drive the lead screw 900 to rotate forward, the lead screw 900 is used to drive the moving plate 600, the electric wrench assembly 700 and the converter module to move close to the control cabinet, and the reverse rotation button 7003 is used to make the electric wrench head 7001 rotate reversely, and the electric wrench head 7001 is used to install the screws on the converter module.

[0119] The converter module replacement device provided by the embodiment provides stable support through the base, the lifter drives the lifting platform to move up and down, the moving plate is slidingly connected on the lifting platform and moves horizontally through the lead screw and the motor, and the electric wrench assembly is connected with the moving plate through the double-headed screw rod to disassemble and install the converter module. During the disassembly process, the forward rotation button controls the electric wrench head to rotate forward to loosen the screws, the motor drives the lead screw to rotate reversely to drive the moving plate and the electric wrench assembly to move away from the control cabinet, and the lifter drives the lifting platform to move downward.
