Description

Technical Field

[0001] This application relates to the field of equipment power supply, and more particularly to a power distribution device and production equipment. Background Technology

[0002] On the production line, the driving of various production equipment requires the use of power cabinets. Each production equipment corresponds to a power cabinet, so that the power cabinet can distribute the electrical energy of the upper-level power distribution system to the corresponding production equipment.

[0003] Existing production line equipment typically uses vertical power cabinets, which are usually placed near the equipment for easy electrical connection. However, with large and complex production equipment, the space occupied by the equipment and power cabinet is significant, reducing the operator's workspace and encroaching on space for other tools and equipment. This reduces operator flexibility and impacts work efficiency. One solution is to bury the power cabinet underground to reduce surface space usage. However, this method requires removing the covering during maintenance, making maintenance difficult and affecting convenience. Utility Model Content

[0004] The purpose of this application is to provide a power distribution device and production equipment, which aims to solve the technical problems of difficulty in power cabinet maintenance and reduced convenience of maintenance caused by the current method of setting up power cabinets underground.

[0005] A first aspect of this application provides a power distribution device, the power distribution device comprising: The support base and cover plate are provided. The top of the support base is provided with a support surface, which is suitable for placing processing equipment. The support base is provided with a mounting groove and an inspection port, which communicates with the mounting groove. The cover plate is suitable for covering the inspection port. A power distribution circuit is provided in the mounting slot and connected to the support base. The input terminal of the power distribution circuit is adapted to be connected to a power source, and the output terminal of the power distribution circuit is connected to a power supply line. The output terminal of the power supply line is connected to the processing equipment.

[0006] In the above-mentioned solution, the power distribution device provided in this application includes a support base, a cover plate, and a power distribution circuit. The top of the support base is provided with a support surface, allowing the processing equipment to be placed on the support surface. The support base is provided with a mounting groove to house the power distribution circuit, thereby separating the power distribution circuit from the processing equipment, reducing the space occupied on the support surface. The support base is also provided with an inspection port. During operation, the inspection port is sealed by the cover plate, allowing workers to step on the cover plate to perform corresponding operations, resulting in a larger working range and increased operational flexibility. During maintenance, workers can open the cover plate to inspect the power distribution circuit in the mounting groove, increasing the convenience of maintenance.

[0007] Optionally, the inner wall of the inspection port is provided with a stepped surface, the cover plate overlaps with the stepped surface, and the top surface of the cover plate is flush with the support surface.

[0008] In the above solution, by setting a stepped surface on the inner wall of the access port, the cover plate and the access port are adapted to form an overlapping fit. The stepped surface provides circumferential restraint for the cover plate (limiting horizontal displacement) and provides vertical support through the surface contact of the overlapping surface, effectively constraining the degree of freedom of the cover plate. Structurally, it avoids the shaking problem caused by assembly gaps after connection, improves the structural stability and reliability of the cover plate after installation, and the top surface of the cover plate is flush with the support surface, which facilitates the movement of personnel on the cover plate and the support surface.

[0009] Optionally, the side of the cover plate closest to the support surface is hinged to the support base.

[0010] In the above scheme, the hinged connection provides a fixed hinge axis for the cover plate, so that the cover plate can rotate around the hinge axis, ensuring that the cover plate moves along a preset trajectory during the opening and closing process, avoiding deviation or jamming, and at the same time increasing the convenience of opening or closing the cover plate.

[0011] Optionally, the cover plate is a transparent cover plate.

[0012] In the above scheme, the use of a transparent cover plate design allows staff to visually observe the status of the power distribution circuit inside the installation slot, enabling timely detection of abnormalities and facilitating timely maintenance.

[0013] Optionally, the cover plate is provided with a wire groove, and the power supply line passes through the wire groove.

[0014] In the above scheme, the cable trays constrain the power supply lines through pre-set structured channels, avoiding messy laying of the lines on the cover plate surface and reducing the risk of the lines crossing and tangling.

[0015] Optionally, the support base is provided with a wire hole, one end of which penetrates the support surface and the other end of which communicates with the mounting groove, and the power supply line passes through the wire hole.

[0016] In the above solution, a wire hole is set on the support base to hide the power supply line and avoid the power supply line from being exposed. This prevents the power supply line from being exposed to the outside and subjected to collisions, friction, and squeezing, reducing faults such as damage to the insulation layer and breakage of the core wire, and increasing the service life.

[0017] Optionally, the power distribution device further includes a converter circuit and an operating device. The power distribution circuit is connected to the processing equipment through the converter circuit. The operating device is disposed on the support surface and is electrically connected to the converter circuit. It is also adapted to adjust the output parameters of the power distribution circuit through the converter circuit.

[0018] In the above scheme, the staff can adjust the output parameters of the power distribution circuit through the operating device, thereby adjusting the working parameters of the processing equipment and increasing the convenience of adjustment.

[0019] Optionally, the power distribution device further includes a cooling device, which is disposed on the support base, and the air outlet of the cooling device is connected to the mounting groove.

[0020] In the above solution, a cooling device can be used to supply cool air toward the mounting slot to dissipate heat from the power distribution circuit inside the mounting slot, thereby controlling the temperature of the power distribution circuit within a safe range and avoiding affecting the performance of the power distribution circuit.

[0021] Optionally, the power distribution device further includes an installation cabinet, which is located in the installation slot and connected to the support base, and the power distribution circuit is located in the installation cabinet and connected to the installation cabinet.

[0022] In the above scheme, the power distribution circuit is connected to the installation cabinet, and then the installation cabinet is connected to the support base, which can increase the convenience and stability of installation.

[0023] A second aspect of this application provides a production device, including a device body and the aforementioned power distribution device, wherein the device body is disposed on the support surface, and the output terminal of the power supply line of the power distribution device is electrically connected to the device body.

[0024] It should be noted that the technical effects brought about by the second aspect of this application can be referred to the technical effects brought about by the corresponding implementation of the first aspect, and will not be repeated here. Attached Figure Description

[0028] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0029] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0031] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0032] Combination Figure 1 and Figure 2As shown in the figure, this application embodiment provides a power distribution device, which includes a support base 1, a cover plate 2, and a power distribution circuit 41. The support base 1 should have a certain length and width so that the cross-sectional area of ​​the support base 1 is large enough. The top of the support base 1 is provided with a support surface, so that the support surface meets the design requirements. The support surface is suitable for placing processing equipment, wherein the processing equipment includes lathes, milling machines, or other functional processing equipment (for mechanical equipment such as component transfer and unpacking), without limitation. The support base 1 is provided with a mounting groove and an inspection port 11. The inspection port 11 is connected to the mounting groove, and the size of the inspection port 11 should be large enough for personnel to pass through. The cover plate 2 is suitable for covering the inspection port 11. When the power distribution device is in use, the cover plate 2 is closed to the inspection port 11. When the power distribution device is under maintenance, the cover plate 2 can be removed to expose the inspection port 11, and personnel can enter the mounting groove through the inspection port 11. The support base 1 can be set on the ground, or the support base 1 can be set in a groove in the ground, without limitation.

[0033] The power distribution circuit 41 is located in the mounting slot and connected to the support base 1. The connection method can be bolted or welded, etc., without restriction. Personnel can enter the mounting slot through the inspection port 11 to inspect the power distribution circuit 41. The input terminal of the power distribution circuit 41 is suitable for connecting to a power source, and the output terminal of the power distribution circuit 41 is connected to a power supply line. The output terminal of the power supply line is connected to the processing equipment. The power distribution circuit 41 can distribute electrical energy from the power source to the processing equipment in the power system.

[0034] In some examples, the support surface is located on one side of the cover plate 2, so that the processing equipment installed on the support surface is located on one side of the cover plate 2, avoiding the processing equipment from affecting the opening or closing of the cover plate 2, increasing the convenience of operating the cover plate 2, and when the cover plate 2 is closed, the staff can step on the cover plate 2 to carry out the corresponding work without occupying the staff's work space, making the staff's operation more flexible.

[0035] In some examples, the power distribution circuit 41 includes a power interface module, a power distribution unit, a protection unit, and a load interface module. The power interface module is used to electrically connect to the power supply to achieve compatible connection between the power supply and subsequent circuits. The power distribution unit is electrically connected to the power interface module and is used to split or combine power. When the input is a single power supply, the power is distributed into multiple independent outputs according to the load's power requirements, voltage level, and physical layout. When the input is multiple power supplies, the multiple power supplies are first combined and then split to ensure that each load receives a matching power supply. The protection unit is electrically connected to the output of the power distribution unit and includes protective devices such as fuses, circuit breakers, and residual current devices (RCDs). (Fuses are used for rapid disconnection of overload and short-circuit faults, circuit breakers are used for disconnection of overload, short-circuit, and undervoltage faults, and RCDs are used for detection and disconnection of leakage faults.) The function of the protection unit is to quickly disconnect the faulty branch or the entire circuit when a circuit fault occurs, to prevent the fault from spreading and to protect the safety of electrical equipment and personnel. The output of the protection unit is electrically connected to the load interface module, which in turn is electrically connected to different electrical components of the processing equipment (such as drive motors, control modules, and actuators) through power supply lines to achieve the final supply of electrical energy.

[0036] The power distribution device provided in this embodiment includes a support base 1, a cover plate 2, and a power distribution circuit 41. The top of the support base 1 is provided with a support surface, allowing the processing equipment to be placed on the support surface. The support base 1 is provided with a mounting groove to house the power distribution circuit 41, thereby separating the power distribution circuit 41 from the processing equipment and reducing the space occupied on the support surface. The support base 1 is also provided with an inspection port 11. During operation, the inspection port 11 is sealed by the cover plate 2, allowing workers to step on the cover plate 2 to perform corresponding operations, resulting in a larger working range and increased operational flexibility. During maintenance, workers can open the cover plate 2 to inspect the power distribution circuit 41 in the mounting groove, increasing the convenience of maintenance.

[0037] In some implementations, combined Figure 1 and Figure 2 As shown, the inner wall of the access port 11 is provided with a stepped surface. The cover plate 2 matches the shape of the access port 11 so that the cover plate 2 overlaps with the stepped surface, preventing the cover plate 2 from shaking after connection. The top surface of the cover plate 2 is flush with the support surface.

[0038] In this design, by setting a stepped surface on the inner wall of the access port 11, the cover plate 2 and the access port 11 are adapted to form an overlapping fit. The stepped surface provides circumferential restraint (limiting horizontal displacement) for the cover plate 2, and provides vertical support through the surface contact of the overlapping surface, effectively constraining the degree of freedom of the cover plate 2. Structurally, it avoids the shaking problem caused by assembly gaps after connection, improves the structural stability and reliability of the cover plate 2 after installation, and the top surface of the cover plate 2 is flush with the support surface, which facilitates the movement of personnel on the cover plate 2 and the support surface.

[0039] In some examples, the side of the cover plate 2 closest to the support surface is hinged to the support base 1. It is understood that because one side of the cover plate 2 is hinged to the support base 1, the cover plate 2 can rotate around the hinge axis. Therefore, there should be a certain gap between one side of the cover plate 2 and the inner wall of the access port 11 to allow for rotation space. Similarly, there should also be a certain gap between the other side of the cover plate 2 (opposite to one side of the cover plate 2) and the inner wall of the access port 11 to allow for rotation space on the other side of the cover plate 2. It is also understood that a certain gap can be reserved between the other two sides of the cover plate 2 and the inner wall of the access port 11, so that the cover plate 2 does not contact the inner wall of the access port 11 when rotating, increasing the smoothness of the cover plate 2's rotation.

[0040] In this design, the hinged connection provides a fixed hinge axis for the cover plate 2, allowing the cover plate 2 to rotate around the hinge axis. This ensures that the cover plate 2 moves along a preset trajectory during the opening and closing process, avoiding deviation or jamming, and at the same time increasing the convenience of opening or closing the cover plate 2.

[0041] In some examples, a handle is provided at the top of the cover plate 2 on the side away from the support surface to increase the convenience of operators operating the cover plate 2, and the handle does not protrude from the surface of the cover plate 2 to avoid affecting the operator's movement. Understandably, a handle may also be provided at the top of the cover plate 2 on the side away from the support surface; these are not restrictive.

[0042] In some embodiments, the cover plate 2 is a transparent cover plate, which may include transparent polyethylene plate, transparent acrylic plate or polycarbonate plate, etc., without limitation.

[0043] In this design, the use of a transparent cover makes it easy for staff to visually observe the status of the power distribution circuit 41 inside the installation slot, so as to detect abnormalities in a timely manner and facilitate timely maintenance.

[0044] It is understandable that cover plate 2 can also be a non-transparent plate. In this case, staff can open cover plate 2 periodically for inspection and maintenance without any restrictions.

[0045] In other embodiments, the area of ​​the cover plate 2 is larger than the area of ​​the access port 11. In this case, when the cover plate 2 covers the access port 11, the bottom edges of the cover plate 2 overlap the outer periphery of the access port 11, which can also ensure the coverage and stable support of the cover plate 2.

[0046] It is evident that the way the cover plate 2 covers the inspection port 11 is not limited and can be designed according to actual needs.

[0047] In some implementations, such as Figure 1 As shown, the cover plate 2 has a wire groove 21 through which the power supply line passes. One end of the power supply line is connected to the output terminal of the power distribution circuit 41, and the other end passes through the wire groove 21 and connects to the processing equipment. During the opening process, the cover plate 2 stretches the power supply line located in the mounting groove. Therefore, the portion of the power supply line located in the mounting groove should be bent to allow for stretching. When the cover plate 2 is opened, the power supply line is gradually straightened without pulling on the power supply line or its interface, ensuring safe use. Simultaneously, the power supply line unfolds, exposing the power distribution circuit 41 in the mounting groove, facilitating maintenance and improving ease of repair. When the cover plate 2 is closed, the power supply line can be bent and stacked to avoid affecting the closing of the cover plate 2.

[0048] In some examples, the cable tray 21 runs through the top and bottom of the cover plate 2. In this case, the power supply line passes through the cable tray 21 and extends through the top of the cover plate 2 to the wiring position of the processing equipment.

[0049] In other examples, the wire groove 21 passes through the bottom of the cover plate 2 and extends inside the cover plate 2 toward the support surface. The other end of the wire groove 21 passes through one side of the cover plate 2. In this case, the power supply line passes through one side of the cover plate 2 and extends to the wiring position of the processing equipment. Alternatively, after passing through one side of the cover plate 2, the power supply line passes through the through hole on the support base 1 and connects to the wiring position of the processing equipment. There are no restrictions.

[0050] In this design, the cable tray 21 constrains the power supply line through a pre-set structured channel, avoiding messy wiring on the surface of the cover plate 2 and reducing the risk of wiring crossing and tangling.

[0051] In some implementations, such as Figure 2 As shown, the support base 1 is provided with a wire hole 12. One end of the wire hole 12 penetrates the support surface, and the other end of the wire hole 12 is connected to the mounting groove. The power supply line passes through the wire hole 12. At this time, one end of the power supply line is connected to the output terminal of the power distribution circuit 41, and the other end of the power supply line passes through the wire hole 12 and is connected to the processing equipment.

[0052] In this design, a wire hole 12 is provided on the support base 1 to hide the power supply line and prevent the power supply line from being exposed. This prevents the power supply line from being exposed to the outside and subjected to collisions, friction, and squeezing, reducing faults such as damage to the insulation layer and breakage of the core wire, and increasing the service life.

[0053] As can be seen, there are no restrictions on the way power supply lines are laid, and the design can be carried out according to actual needs.

[0054] In some implementations, combined Figure 1 and Figure 2 As shown, the power distribution device also includes a converter circuit 42 and an operating device 5. The power distribution circuit 41 is connected to the processing equipment through the converter circuit 42. The operating device 5 is disposed on the support surface and is electrically connected to the converter circuit 42. It is also suitable for adjusting the output parameters of the power distribution circuit 41 through the converter circuit 42.

[0055] In some examples, the operating device 5 includes an operating cabinet and a control panel mounted on the cabinet. The control panel is electrically connected to the converter circuit 42 for easy parameter adjustment. The converter circuit 42 includes a frequency converter, and the power distribution circuit 41 is connected to the processing equipment through the frequency converter. The control panel is electrically connected to the frequency converter through control lines, enabling the setting, modification, and real-time monitoring of adjustable operating parameters such as the frequency converter's output frequency, speed, torque limit, and acceleration / deceleration time, and displaying the frequency converter's operating status. The frequency converter can be an AC-AC frequency converter, an AC-DC-AC frequency converter, etc., without limitation.

[0056] With this design, operators can adjust the parameters output by the power distribution circuit 41 through the operating device 5, thereby adjusting the working parameters of the processing equipment and increasing the convenience of adjustment.

[0057] In some implementations, reference continues. Figure 1 and Figure 2 The power distribution device also includes a cooling device 6, which is mounted on the support base 1. The air outlet of the cooling device 6 is connected to the mounting groove. The cooling device 6 includes an air conditioner or a cooling fan, etc., without limitation.

[0058] In this design, the cooling device 6 can provide cool air toward the mounting slot to dissipate heat from the power distribution circuit 41 in the mounting slot, keeping the temperature of the power distribution circuit 41 within a safe range and avoiding affecting the performance of the power distribution circuit 41.

[0059] In some embodiments, the power distribution device also includes a mounting cabinet 4 with an open top. The mounting cabinet 4 can be placed flat in the mounting slot to reduce vertical space occupation. The mounting cabinet 4 is located in the mounting slot and connected to the support base 1. The power distribution circuit 41 is located in the mounting cabinet 4 and connected to the mounting cabinet 4. The mounting cabinet 4 can be the cabinet of the power cabinet, and the power distribution circuit 41 is part of the power cabinet, that is, the power cabinet is set in the mounting slot and connected to the support base 1.

[0060] In some examples, the top outer periphery of the mounting cabinet 4 is provided with a connection hole, and the support base 1 is provided with a screw hole at the position corresponding to the connection hole. After the bolt passes through the connection hole, it is screwed into the screw hole until the nut of the bolt abuts against the mounting cabinet 4, thereby realizing the bolt connection between the mounting cabinet 4 and the support base 1, and increasing the convenience of disassembling and assembling the mounting cabinet 4 and the support base 1.

[0061] In this design, the power distribution circuit 41 is connected to the mounting cabinet 4, and then the mounting cabinet 4 is connected to the support base 1, which can increase the convenience and stability of installation.

[0062] In some implementations, a signal receiver is also installed inside the power cabinet. The signal receiver can be connected to the signal transmitter wirelessly or via a wire. The signal receiver is also electrically connected to the frequency converter. The worker holds a control device, which contains a signal transmitter. The control device is equipped with adjustment keys. When the adjustment keys are operated, the signal transmitter sends an electrical signal to the signal receiver. After receiving the electrical signal, the signal receiver controls the adjustment of the frequency converter parameters.

[0063] In some implementations, the power cabinet is equipped with lifting rings that are suitable for connection to lifting ropes, allowing workers to move the power cabinet by operating the lifting ropes. Alternatively, workers can use external mechanical equipment to move the power cabinet by connecting the mechanical equipment to the lifting ropes, thereby increasing the convenience of transporting the power cabinet.

[0064] The power distribution device provided in this embodiment integrates the power distribution circuit 41 (power cabinet) inside the support base 1. Processing equipment can be installed on the top of the support base 1, and workers can also stand on the support base 1. This maximizes the use of the vertical space inside the factory. The power cabinet is placed flat inside the support base 1, allowing workers or processing equipment to stand or be placed on the top of the power cabinet. This improves the space utilization rate inside the factory, reduces the floor area occupied by the power cabinet, and makes the space for placing processing equipment and the space for workers to operate more ample.

[0065] Combination Figure 1 and Figure 2As shown, this application also provides a production equipment, including an equipment body 3 and the aforementioned power distribution device. The power distribution device includes all the technical features of the aforementioned power distribution device. The equipment body 3 is disposed on a support surface, and the output end of the power supply line of the power distribution device is electrically connected to the equipment body 3.

[0066] In this design, the equipment body 3 is placed on the support surface of the power distribution device, and the power distribution circuit 41 is placed in the mounting groove. This separates the power distribution circuit 41 from the processing equipment, reducing the space occupied on the support surface.

[0067] In some implementations, there are multiple power distribution devices, which are used in conjunction with each other. In this case, the support bases 1 of the multiple power distribution devices are arranged side by side, and the support surfaces of the multiple support bases 1 arranged side by side are flush to form a stable support structure. The multiple equipment bodies 3 are placed on the corresponding support surfaces. The empty support surfaces and the top of the cover plate 2 form a plane that allows the staff to move, ensuring that the staff's movement range meets the operating space requirements.

[0068] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0069] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
