Description

Technical Field

[0001] This invention relates to the field of control cabinets, and in particular to a modular control cabinet for gate pump control and its control method. Background Technology

[0002] In the fields of water conservancy engineering, water supply and drainage systems, and industrial fluid control, gate pump control systems are one of the core infrastructures. Their stability and maintainability directly affect the operational efficiency and safety of the entire system. The control cabinet, as the central hub of the gate pump control system, typically integrates multiple control units to perform functions such as data acquisition, logic operations, power drive, and remote monitoring.

[0003] Traditional control cabinets employ a fixed structural design with standardized mounting slots inside. Each module is installed in a specific slot according to its functional requirements. While this design ensures the mechanical stability of the modules to a certain extent, it has significant drawbacks in actual installation and maintenance. Specifically, after the control unit is inserted into the mounting slot, the operator must perform electrical wiring operations from the back of the control cabinet. Since each control unit typically requires connection to multiple cables, including power lines, signal lines, communication buses, and grounding wires, the number of cables is numerous and the interfaces are dense. This wiring process is not only time-consuming and labor-intensive but also easily leads to a messy and tangled cable arrangement inside the cabinet. Summary of the Invention

[0004] To simplify the installation process of the control cabinet, this invention provides a modular control cabinet for gate pump control and its control method.

[0005] In a first aspect, the present invention provides a modular measurement and control cabinet for gate pump control, which adopts the following technical solution:

[0006] A modular control cabinet for gate pump control includes a cabinet body and multiple modular units installed within the cabinet body, and further includes:

[0007] The modular circuit board is lifted and installed inside the cabinet, corresponding one-to-one with the module unit, and is electrically connected according to its function.

[0008] A cable conversion assembly connects the module unit and the module circuit board;

[0009] The selection mechanism abuts against the module unit and is used to select the module circuit board to match the module unit;

[0010] The cabinet has multiple mounting slots for the module units to be freely selected and inserted, as well as a receiving chamber for the module circuit boards to be pre-installed.

[0011] The selection mechanism includes multiple selection units that correspond one-to-one with the module units. Each selection unit has a selection element for selecting the module circuit board to drive the module circuit board to descend from the receiving chamber and a positioning element for positioning the module circuit board to match the mounting slot when it descends. The positioning element corresponds one-to-one with the mounting slot.

[0012] Each module unit has an abutting part that abuts against the corresponding selection unit. When the module unit is inserted into the mounting slot, the abutting part drives the corresponding selection unit to move to select the corresponding module circuit board to descend and position it in a position that matches the corresponding mounting slot, so that the module unit and the corresponding module circuit board can be automatically connected.

[0013] By adopting the above technical solution, the supplier pre-installs the module circuit boards in the receiving chamber and ships them out of the factory. When installing the control cabinet, the module units are automatically inserted into the installation slots. At this time, the module units can select the corresponding module circuit boards through the selection mechanism and drop them down. The connection between the module circuit boards and the module units is automatic through the cable conversion components. The connection process between the module circuit boards and the module units does not require manual operation. After the module circuit boards are positioned, the operator can connect the electrical circuits of the functionally related module circuit boards from the back of the cabinet. At this time, there are fewer electrical cables to be connected, and the installation and wiring are more convenient.

[0014] Optionally, the inner wall of the cabinet has a selection chamber for the selection mechanism to be installed; the selection member and the positioning member are both slidably installed in the selection chamber, one selection member and multiple positioning members are synchronously engaged, and the end of the positioning member abuts against the abutting part.

[0015] Optionally, the positioning member has a snap-fit ​​groove for the selection member to snap into, the snap-fit ​​groove having a first station and a second station; when the selection member is located at the first station, the selection member locks the corresponding module circuit board in the receiving cavity; when one of the positioning members drives the selection member to move to the second station, the selection member releases the corresponding module circuit board.

[0016] Optionally, the cable conversion assembly includes a conversion plate installed at the rear of the module unit for converting the cable connector of the module unit into a pin, and a connection plate disposed in the cabinet for the pins of the conversion plate to be inserted to connect with the module circuit board.

[0017] The conversion board corresponds one-to-one with the module unit with pins and pin numbers distributed in different positions; the connecting board array has insertion holes for the pins of the conversion board to be inserted, and the insertion holes are provided with deformation components for driving the pins of the conversion board to fully abut against the conductive parts of the module circuit board.

[0018] Optionally, the deformable component includes an expansion portion that is inserted into the insertion hole and bends outward, and a limiting portion connected to both ends of the expansion portion and used to limit the deformable component within the insertion hole;

[0019] Multiple deformation guide strips are spaced apart inside the expansion section, and the deformation guide strips are elastically connected to the expansion section by rubber strips; the pins of the conversion plate pass through the insertion hole and abut against the deformation guide strips to drive the deformation guide strips to deform and abut against the conductive parts of the module circuit board.

[0020] Optionally, the top surface of the cabinet is provided with a slow-descent mechanism corresponding to each of the module circuit boards. The slow-descent mechanism includes a drum rotatably disposed in the cabinet, a winding wire wound around the drum, and a first magnetic sheet connected to the lower end of the winding wire. The top of the module circuit board has a second magnetic sheet that magnetically engages with the first magnetic sheet.

[0021] Optionally, the cabinet is equipped with an electric push rod. When the module circuit board descends to the back of the corresponding module unit via the slow-descent mechanism, the electric push rod drives the module circuit board to press against the cable conversion assembly.

[0022] Optionally, the cabinet side wall has an installation port that extends through to the receiving chamber, and the receiving chamber is divided into several partition slots that correspond one-to-one with the module circuit board.

[0023] Secondly, this application provides a control method for a modular measurement and control cabinet for gate pump control, which adopts the following technical solution:

[0024] A control method for a modular control cabinet for gate pump control, applied to a modular control cabinet for gate pump control, comprising:

[0025] Image acquisition module circuit board;

[0026] The module circuit board image is analyzed to determine whether the conductive positions of the module circuit board deviate from those of the cable conversion assembly.

[0027] When deviations exist, the type of deviation is determined based on the module circuit board image. The types of deviations include displacement deviation and tilt deviation.

[0028] Based on displacement deviation, the offset distance is determined according to the module circuit board image;

[0029] The preset electric push rod is controlled to move according to the offset distance, which in turn drives the module circuit board to adjust its position.

[0030] Based on the tilt deviation, the module circuit board is removed and reinstalled using a preset reset method.

[0031] Optionally, the reset method includes:

[0032] Determine the preset magnetic sheet position of the second magnetic sheet from the module circuit board image;

[0033] The magnetic attraction range is determined based on the position of the magnetic sheet and the preset magnetic force intensity;

[0034] Release the preset winding cable according to the horizontal height of the magnetic sheet's position to lower the preset first magnetic sheet;

[0035] The rotation angle of the air guide plate pre-installed in the cabinet is determined based on the position of the magnetic sheet.

[0036] The air guide plate is rotated to face the first magnetic plate, so as to guide the airflow of the cooling fan preset in the cabinet and drive the first magnetic plate to swing, and capture the attraction image.

[0037] Determine whether the first and second magnets are attracted from the attraction image;

[0038] When the two are attracted together, the winding is wound up at a preset winding distance to remove the module circuit board. After the removal is completed, the electric push rod is controlled to drive the module circuit board to reset.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The supplier pre-installs the modular circuit boards in the receiving chamber and ships them from the factory. When installing the control cabinet, the modular units are automatically inserted into the installation slots. At this time, the modular units can select the corresponding modular circuit boards through the selection mechanism and drop them down. The connection between the modular circuit boards and the modular units is automatic and requires no manual operation. After the modular circuit boards are positioned, the operator can connect the electrical wiring of the functionally related modular circuit boards from the back of the cabinet. At this time, there are fewer electrical cables to be connected, and the installation and wiring are relatively convenient.

[0041] 2. A conversion board is used to process the numerous cable connectors on the back of the module unit, unifying them into a pin-type structure. A connecting board then connects the pins to the module circuit board. This structure changes the traditional cable wiring method, reducing the number of cables inside the cabinet and simplifying wiring.

[0042] 3. When the pins of the conversion board enter the insertion hole, the pins abut against the deformation guide strip of the deformation component, thereby increasing the contact area between the pins and the module circuit board, making it less likely for poor contact to occur.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0052] This application discloses a modular measurement and control cabinet for gate pump control.

[0053] Reference Figure 1 and Figure 2 A modular control cabinet for gate pump control includes a cabinet 1 and modular units 2, modular circuit boards 3, cable conversion components 4, and selection mechanisms 5 installed within the cabinet 1. Modular unit 2 is the control unit of the control cabinet, used for data acquisition and processing. Modular circuit board 3 is a PCB board used for cable connection and interaction. Cable conversion component 4 converts the cable connectors on the back of modular unit 2 into pin-type structures and is used to connect modular unit 2 and modular circuit board 3. Selection mechanism 5 is used to select the modular circuit board 3 that matches modular unit 2.

[0054] In this embodiment, there are multiple module units 2, and each module unit 2 has a different function and a different cable connector on its back. The number of module circuit boards 3 is the same as the number of module units 2, and the two are used in a one-to-one correspondence in function. Each module circuit board 3 has a conductive part on its back that communicates with the module unit 2, and the position and structure of the conductive part are also different.

[0055] The cabinet 1 is a cuboid, which has multiple mounting slots 11 for installing module units 2, a receiving chamber 12 for pre-placing module circuit boards 3, a wiring chamber 13 for lifting and lowering module circuit boards 3 and cable arrangement, and a selection chamber 14 for installing selection mechanism 5.

[0056] Selecting chamber 14 is located on both sides of mounting slot 11 and separated from it by a partition. Wiring chamber 13 is located on the rear side of cabinet 1, that is, behind mounting slot 11. Receiving chamber 12 is located above wiring chamber 13, so that the module circuit board 3 can descend from receiving chamber 12 to wiring chamber 13 under the action of gravity.

[0057] The cabinet 1 has a mounting opening 15 on its side wall that extends into the receiving chamber 12. The receiving chamber 12 is divided into several partition slots 121, each corresponding to a module circuit board 3 for insertion. In this embodiment, each partition slot 121 has a corresponding specific module circuit board 3, and the module circuit boards 3 are selectively inserted into the partition slots 121 according to their functions. When the control cabinet supplier ships the control cabinet, the module circuit boards 3 are pre-installed in the receiving chamber 12 according to their functions.

[0058] Reference Figure 1 , Figure 2 and Figure 3The mounting slot 11 has multiple symmetrical insertion ports on both sides of its inlet, which extend into the selection chamber 14. The module unit 2 has an abutment portion 21, which can be inserted into the insertion port when the module unit 2 is installed into the mounting slot 11. The abutment portion 21 is positioned differently on different module units 2, allowing it to be selectively inserted from different positions within the insertion port.

[0059] Reference Figure 1 , Figure 2 and Figure 4 The selection mechanism 5 includes multiple selection units 51, each corresponding to a module unit 2. When a module unit 2 is inserted into the mounting slot 11, the module unit 2 selects the corresponding module circuit board 3 through the corresponding selection unit 51.

[0060] The selection unit 51 includes a selection element 52 and a positioning element 53. The selection element 52 is used to select the module circuit board 3 to drive the module circuit board 3 down from the receiving chamber 12. The positioning element 53 is used to position the module circuit board 3 during the descent process so that it eventually stops in a position that matches the mounting slot 11.

[0061] In this embodiment, each selection unit 51 has one selection element 52 and multiple positioning elements 53, the number of which is the same as that of module units 2. Both the selection element 52 and the positioning elements 53 are slidably mounted in the selection chamber 14. The selection element 52 includes a selection part 521 and a snap-fit ​​part 522 connected to the selection part 521. The positioning element 53 includes a positioning part 531 and a driving part 532 connected to the positioning part 531.

[0062] The selection section 521 is located at the bottom of the receiving chamber 12, and the selection sections 521 of all selection units 51 are stacked. The selection section 521 has a first support piece 523, and the first support piece 523 of each selection unit 51 is staggered to limit and support the corresponding module circuit board 3 so that the module circuit board 3 will not fall out of the receiving chamber 12.

[0063] The positioning part 531 of the positioning member 53 is located below the selection part 521. Since there are multiple positioning members 53, multiple positioning positions are formed, and the positioning part 531 of each positioning position corresponds one-to-one with the position of the mounting slot 11. At the positioning position, the positioning parts 531 of all selection units 51 are stacked, and the positioning part 531 has a second support piece 533. The second support piece 533 of each selection unit 51 is staggered to intercept and support the corresponding falling module circuit board 3, so that the module circuit board 3 can be matched and installed with the module unit 2 of the mounting slot 11.

[0064] Reference Figure 2 , Figure 4 and Figure 5The drive unit 532 has a latching slot 534, and the latching part 522 of each selection unit 51 passes through the latching slot 534 of the drive unit 532. That is, the drive unit 532 of any positioning member 53 can drive the latching part 522 to move. The latching slot 534 has a first station and a second station. When the latching part 522 of the selection member 52 is located at the first station, the first support piece 523 of the selection part 521 is directly opposite to the module circuit board 3, thereby locking the corresponding module circuit board 3 in the receiving chamber 12. When the drive unit 532 of one of the positioning members 53 moves and drives the latching part 522 to move to the second station, the first support piece 523 is misaligned with the corresponding module circuit board 3, thereby releasing the module circuit board 3.

[0065] During this process, the second support piece 533 of the selected moving positioning member 53 is directly opposite to the module circuit board 3, while the second support piece 533 of the stationary positioning member 53 is misaligned with the module circuit board 3. Therefore, the module circuit board 3 can pass through the misaligned second support piece 533 and be limited to the directly opposite second support piece 533 during the falling process.

[0066] Reference Figure 1 , Figure 2 and Figure 4 Each positioning element 53 has its drive part 532 end facing the insertion ports on both sides of the inlet of the mounting slot 11. When the module unit 2 is inserted into the mounting slot 11, the abutment part 21 abuts against one end of the drive part 532 of the corresponding selection unit 51 and drives it to move. The positioning element 53 can drive the selection element 52 to move, thereby dropping the corresponding module circuit board 3. The moving positioning element 53 can support the module circuit board 3 during the falling process.

[0067] Reference Figure 2 and Figure 6 To allow the circuit board 3 to descend slowly, a slow-descent mechanism 6 is provided on the top surface of the cabinet 1. The slow-descent mechanism 6 is located in the receiving chamber 12 and corresponds one-to-one with each circuit board 3. The slow-descent mechanism 6 includes a drum 61, a winding cable 62, and a first magnetic plate 63. The drum 61 is rotatably mounted, and damping exists between it and the rotating shaft to allow it to rotate slowly. The winding cable 62 is wound around the drum 61, and the first magnetic plate 63 is connected to the bottom of the winding cable 62. The top of the circuit board 3 has a second magnetic plate 31, which magnetically engages with the first magnetic plate 63.

[0068] When the module circuit board 3 falls, the winding cable 62 can pull the module circuit board 3, so that the module circuit board 3 falls slowly.

[0069] In other embodiments, the drum 61 may also be driven by a micro motor, which drives the module circuit board 3 to descend.

[0070] Reference Figure 2 and Figure 4 Furthermore, since the module circuit board 3 does not come into contact with the cable conversion assembly 4 when it falls onto the positioning member 53, an electric push rod 7 is provided in the wiring chamber 13 to ensure full contact between the two. The end of the electric push rod 7 has a suction cup. After the module circuit board 3 is positioned, the electric push rod 7 extends and comes into contact with the module circuit board 3 through the suction cup, and then drives the module circuit board 3 to move horizontally and come into contact with the cable conversion assembly 4.

[0071] Reference Figure 3 In this embodiment, the cable conversion assembly 4 is provided to facilitate wiring. The cable conversion assembly 4 includes a conversion plate 41 and a connecting plate 42. The conversion plate 41 is connected and fixed to the module unit 2 by studs at its four corners. The conversion plate 41 is used to convert the cable connector of the module unit 2 into a pin connector. The back of the module unit 2 has various types of plugs, which are directly connected to one side of the conversion plate 41, and pins communicating with it are provided on the other side. The pin positions are arranged in an array, and the number of pins at each pin position is determined according to the data transmission requirements of the connector.

[0072] Reference Figure 2 and Figure 3 The connecting plate 42 is a rectangular thin plate, which is fixedly installed in the wiring chamber 13. The connecting plate 42 is used for the insertion of the pins of the conversion board 41 to connect with the module circuit board 3. The connecting plate 42 has an array of insertion holes 421, the positions of which correspond to the positions of the pins.

[0073] Reference Figure 3 and Figure 7 Each insertion hole 421 is provided with a deformation component 43, which is used to drive the pins of the conversion board 41 to fully abut against the conductive parts of the module circuit board 3. The deformation component 43 is Ω-shaped and includes an expansion part 431 and a limiting part 432. The expansion part 431 bends and expands outward, and its cross-section is arc-shaped. When the expansion part 431 is located in the insertion hole 421, the expansion part 431 can limit the deformation component 43 from being pulled out again from the insertion side of the insertion hole 421.

[0074] The limiting part 432 is integrally connected to both ends of the expansion part 431. The limiting part 432 is used to restrict the deformation part 43 so that it is not easily over-inserted and falls out after insertion. The limiting part 432 is bent to form an elastic segment 433, so that the expansion part 431 can be displaced a certain distance within the insertion hole 421.

[0075] The expansion section 431 has a cavity, and multiple deformation guide strips 434 are spaced apart inside it. The deformation guide strips 434 are connected to the expansion section 431 by rubber strips 435. The deformation guide strips 434 are elastic and conductive, while the rubber strips 435 are insulating.

[0076] Combination Figures 1 to 7 When installing module unit 2, first install conversion plate 41 on the back of module unit 2, and then insert module unit 2 into installation slot 11. At this time, the pins of conversion plate 41 can pass through the insertion hole 421 of connecting plate 42 and abut against deformation guide 434, thereby driving the corresponding deformation guide 434 to bend outward.

[0077] After the module unit 2 is installed, the module unit 2 drives the selection mechanism 5 to select the module circuit board 3. The module circuit board 3 falls down and abuts against the connecting plate 42 under the drive of the electric push rod 7. At this time, the conductive part of the module circuit board 3 abuts against the deformation guide strip 434 in the deformation component 43, and the module circuit board 3 separates from the slow descent mechanism 6.

[0078] After completing the above steps, the operator manually connects the functionally related module circuit boards 3 electrically. At this time, there are fewer cables between adjacent module circuit boards 3, making them easier to organize.

[0079] Based on the same inventive concept, embodiments of the present invention provide a control method for a modular control cabinet for gate pump control. The control cabinet is pre-installed with a detection system to check the installation status of the control cabinet, which can be used even when the module units are not fully installed. During installation or use of the control cabinet, if vibration or other factors cause misalignment between the module circuit board and the cable conversion assembly, resulting in poor contact, the detection system can address the specific situation.

[0080] A control method for a modular control cabinet for gate pump control includes the following steps:

[0081] Step S1: Acquire images of the module circuit board.

[0082] The module circuit board image refers to the image obtained by taking a picture of the installed module circuit board 3 through a small camera inside the pre-set cabinet 1. The image can identify the connection between the module circuit board 3 and the cable conversion component 4.

[0083] Step S2: Analyze the module circuit board 3 from the module circuit board image to determine whether the conductive position of the module circuit board 3 is deviated from the cable conversion component 4.

[0084] The conductive positions of module circuit board 3 and the position of the deformable guide strip 434 of cable conversion assembly 4 are analyzed in the module circuit board image to determine whether there is a gap between them, thereby determining whether they are misaligned. When they are misaligned, poor contact will occur between them.

[0085] Step S3: When deviation exists, determine the type of deviation based on the module circuit board image. The types of deviation include displacement deviation and tilt deviation.

[0086] When module circuit board 3 is subjected to vibration, two deviation scenarios may occur: one is horizontal displacement of module circuit board 3, and the other is tilting and jamming of module circuit board 3. These two scenarios can be determined through image recognition analysis of the module circuit board image.

[0087] Step S30: Based on the displacement deviation, determine the offset distance according to the module circuit board image.

[0088] For abnormal displacement deviations, horizontal displacement adjustment is required to restore it to its original position. The offset distance refers to the distance between the conductive position of the module circuit board 3 and the position of the deformable guide strip 434 of the cable conversion assembly 4. The offset distance can be directly obtained from image recognition analysis of the module circuit board image.

[0089] Step S300: Control the preset electric push rod 7 to move according to the offset distance and drive the module circuit board 3 to adjust the displacement.

[0090] The electric push rod 7 is not fixed inside the cabinet 1; it can be adjusted horizontally within the cabinet 1. When the module circuit board 3 deviates abnormally, the electric push rod 7 can be adjusted horizontally, and the adjustment distance is the offset distance. Because the module circuit board 3 is supported by the suction cup at the end of the electric push rod 7, the module circuit board 3 can also be adjusted horizontally when the electric push rod 7 moves.

[0091] Step S31: Based on the tilt deviation, the module circuit board 3 is removed and reinstalled using a preset reset method.

[0092] In the case of abnormal tilting of module circuit board 3, since module circuit board 3 is prone to getting stuck after tilting, it cannot be adjusted by horizontal displacement alone. Therefore, the system adopts a reset method to adjust module circuit board 3. The reset method will not be described in detail here, but will be described in detail in subsequent embodiments.

[0093] The reset method includes the following steps:

[0094] Step S310: Determine the preset magnetic sheet position of the second magnetic sheet 31 from the module circuit board image.

[0095] The second magnetic sheet 31 is located on the top of the module circuit board 3. The position of the second magnetic sheet 31 is the position of the second magnetic sheet 31 after the module circuit board 3 tilts abnormally.

[0096] The features of the second magnetic piece 31 can be identified in the module circuit board image. By analyzing the module circuit board image, the magnetic piece position of the second magnetic piece 31 can be determined.

[0097] Step S311: Determine the magnetic attraction range based on the position of the magnetic sheet and the preset magnetic force intensity.

[0098] In this embodiment, the first magnetic plate 63 of the descent mechanism 6 needs to be lowered and attracted to the second magnetic plate 31, thereby removing the module circuit board 3. The second magnetic plate 31 has a circumferential magnetic field that can directly attract the first magnetic plate 63, so that the first magnetic plate 63 and the second magnetic plate 31 can attract each other without being in complete contact. The range of the circumferential magnetic field of the second magnetic plate 31 is the magnetic attraction range. The size of the magnetic attraction range is related to the magnetic strength; the stronger the magnetic strength, the larger the magnetic attraction range. Therefore, the specific location area of ​​the magnetic attraction range can be determined based on the position of the magnetic plate and the magnetic strength.

[0099] Step S312: Release the preset winding 62 according to the horizontal height of the magnetic sheet position to lower the preset first magnetic sheet 63.

[0100] Once the position of the magnetic sheet is determined, the first magnetic sheet 63 of the slow-descent mechanism 6 can be released, allowing the first magnetic sheet 63 to approach the second magnetic sheet 31.

[0101] Step S313: Determine the rotation angle of the air guide plate preset in the cabinet 1 according to the position of the magnetic sheet.

[0102] There may be a certain horizontal distance between the position of the second magnetic sheet 31 and the descending position of the first magnetic sheet 63. This distance may exceed the magnetic attraction range. To address this, an air guide plate is installed inside the cabinet 1. The air guide plate can rotate and guide the air blown out by the cooling fan inside the cabinet 1. The rotation angle refers to the angle required to rotate the air guide plate toward the second magnetic sheet 31.

[0103] Step S314: Rotate the air guide plate toward the first magnetic plate 63 to guide the airflow of the cooling fan preset in the cabinet 1, thereby driving the first magnetic plate 63 to swing and capturing an image of attraction.

[0104] When the air guide plate is directed towards the second magnetic plate 31, the air blown by the cooling fan is guided by the air guide plate to blow towards the second magnetic plate 31. When the first magnetic plate 63 descends, the first magnetic plate 63 can swing under the action of the wind, thereby entering the magnetic attraction range during the swinging process, at which time the two can attract each other.

[0105] The attraction image is an image obtained by a small camera inside the cabinet 1 capturing the attraction of the first magnetic piece 63 and the second magnetic piece 31.

[0106] Step S315: Determine whether the first magnetic piece 63 and the second magnetic piece 31 are attracted from the attraction image.

[0107] Image recognition is used to ensure that the first magnetic piece 63 and the second magnetic piece 31 have been magnetically attracted before the next step can be performed.

[0108] Step S316: When the two are attracted together, the winding 62 is wound up at a preset winding distance to remove the module circuit board 3. After the removal is completed, the electric push rod 7 is controlled to drive the module circuit board 3 to reset.

[0109] After the two are magnetically attracted, the drum 61, under the action of the micro motor, winds upward a certain distance, which is the winding distance. This winding distance is preset by the technicians and is the distance that allows the module circuit board 3 to be unloaded; details are omitted here. After the slow-descent mechanism 6 pulls the module circuit board 3 out and rises, the slow-descent mechanism 6 can release the module circuit board 3 again. At this time, the module circuit board 3 can be reinstalled according to the initial installation steps of the control cabinet, thereby ensuring a stable connection between the module circuit board 3 and the cable conversion assembly 4.
