Description

Technical Field

[0001] The utility model relates to the technical field of DCS control systems, in particular to a DCS control system and a base thereof. Background Art

[0002] DCS, short for Distributed Control System (DCS), is an automated application system with decentralized control functions and centralized management operations. It is widely used in fields such as power generation, petrochemicals, and metallurgy. Current DCS systems utilize traditional industrial standard cabinets. Some existing cabinets lack bases, while others have bases designed to be integrated with the cabinet.

[0003] For EPR (evolutionary power reactors, or third-generation nuclear reactors), two DCS cabinets must be placed adjacent to each other for operation. Using existing technology to set up a base requires a base at least 1.8 meters long to secure the two 0.9-meter-long DCS cabinets. This design consumes a lot of steel, resulting in high production costs and inconvenient wiring between the cabinets. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0030] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0031] Figure 1 The base 1 in one embodiment of the present invention is shown. It is used in a DCS control system to support a DCS cabinet and facilitate the wiring of cables. The base 1 includes a connecting portion 30 and two supporting portions, wherein the two supporting portions are arranged in parallel and spaced apart. The height of the connecting portion 30 is less than the height of the two supporting portions, and the two ends of the connecting portion 30 are respectively connected to the midpoints of the upper ends of the two supporting portions, so that the structure of the base 1 is an I-shaped structure when viewed from above (such as Figure 2 shown).

[0032] The cabinet is rectangular in shape, with a rectangular lower surface. The base 1 is removably connected to a DCS control system cabinet (not shown). In this embodiment, the lower surface of the cabinet is rectangular, with mounting holes at each corner for removable connection to the base 1. If any two mounting holes with the long axis of the rectangle as their axis of symmetry are considered a group, then the cabinet includes two groups of mounting holes.

[0033] Specifically, at least one connection hole is formed on the upper ends of the two supporting parts of the base 1, respectively, to form at least one connection hole group, which is adapted to two assembly holes (i.e., any one assembly hole group) at the same length position of the cabinet.

[0034] In some embodiments, there are two connection hole groups, spaced apart on the base 1. The distance between the two connection hole groups matches the sum of the distances from two mounting holes at the same width of the cabinet to their adjacent short sides. That is, the sum of the distance between the first mounting hole group and the adjacent short side, and the distance between the second mounting hole group and the adjacent short side, matches the distance between the two connection hole groups. This ensures that the base 1 can be removably connected to two cabinets simultaneously, thereby reducing the use of the base 1 and lowering costs.

[0035] In this embodiment, the two supporting portions are a first supporting portion 10 and a second supporting portion 20, wherein the first supporting portion 10 and the second supporting portion 20 are both longitudinally arranged and spaced apart in parallel. The connecting portion 30 is longitudinally arranged, with its ends connecting the midpoints of the upper ends of the first supporting portion 10 and the midpoints of the upper ends of the second supporting portion 20, respectively.

[0036] See also Figure 3 It should be understood that the heights of the first support portion 10 and the second support portion 20 are matched to ensure stable support. The height of the connecting portion 30 is smaller than that of the first support portion 10 and the second support portion 20, so that there is a distance between the lower end of the connecting portion 30 and the lower ends of the first support portion 10 and the second support portion 20 to facilitate the routing of the DCS control system cables.

[0037] The connection holes formed at the upper ends of the two support parts are now defined as a first connection hole 11 and a second connection hole 21 respectively, that is, at least one first connection hole 11 is formed at the upper end of the first support part 10, and at least one second connection hole 21 is formed at the upper end of the second support part 20.

[0038] In this embodiment, two first connection holes 11 are symmetrically spaced apart on the first support portion 10, and two second connection holes 21 are symmetrically spaced apart on the second support portion 21. The first connection holes 11 and the second connection holes 21, whose connection lines are parallel to the extending direction of the connection portion 30, constitute a connection hole group. Thus, the first support portion 10 and the second support portion 20 include two connection hole groups, each corresponding to the two assembly hole groups.

[0039] It should be understood that the length of the connecting portion 30 needs to be flexibly adjusted according to the distance between the two assembly holes in the assembly hole group, and its length setting needs to make the distance between the first connecting hole 11 and the second connecting hole 21 compatible with the distance between the two assembly holes in the assembly hole group.

[0040] In some embodiments, both ends of the connecting portion 30 are fixed to the first supporting portion 10 and the second supporting portion 20 by welding.

[0041] In some other optional embodiments, the two ends of the connecting portion 30 may also be fixed to the first supporting portion 10 and the second supporting portion 20 by other means such as bolt connection.

[0042] In some embodiments, the connecting hole is a long hole, and the extending direction of the long axis thereof is perpendicular to the extending direction of the connecting portion 30 .

[0043] For example Figure 1 As shown, in this embodiment, the two first connection holes 11 and the two second connection holes 21 are both elongated holes, and the extending direction of their long axes is parallel to the extending direction of the connecting portion 30. This allows for tolerances in the manufacturing and assembly processes during the detachable connection between the cabinet and the base 1, thereby preventing the base 1 from being unable to be detachably connected to two cabinets simultaneously.

[0044] In some embodiments, at least one mounting hole is formed at the lower end of at least one support portion, and the base 1 also includes a first connecting member, which is passed through the mounting hole and at the same time passed through the mounting platform for fixing the base 1.

[0045] Specifically, two mounting holes are formed at intervals on the lower ends of the two supporting parts to improve the stability of the base 1 when it is set on the mounting platform.

[0046] In this embodiment, the first connecting member is an expansion bolt to enhance secure fixation. Two first mounting holes 12 are formed at the lower end of the first support portion 10, and two second mounting holes (not shown) are formed at the lower end of the second support portion 20. Four expansion bolts (not shown) are respectively inserted into the two first mounting holes 12 and the two second mounting holes. The expansion bolts are then inserted into a mounting platform (e.g., the ground) to secure the base 1.

[0047] In other optional embodiments, other connecting members such as ordinary bolts and screws can also be used to achieve the above effects. Alternatively, only one first mounting hole 12 and / or only one second mounting hole can be provided; alternatively, multiple first mounting holes 12 and / or multiple second mounting holes can be provided; the number of the first mounting holes 12 and the number of the second mounting holes can be the same or different, and there is no specific limitation here. The base 1 can be fixed on the platform.

[0048] In some embodiments, at least one support portion is formed by stacking two channel steels so that a vertical cross-section thereof is E-shaped.

[0049] Specifically, the support portion is formed by stacking two channel steels, and at least one fixing hole is formed on each of the two stacked channel steels. The base 1 also includes a second connecting member, and the two channel steels are fixed together by passing the second connecting member through the fixing hole to form a support portion.

[0050] In some embodiments, the two channel steels may be fixed by welding; or after forming a fixing hole and fixing with a second connecting member, the two channel steels may be reinforced by welding.

[0051] See also Figure 3 In this embodiment, the first support portion 10 is formed by stacking two equal-shaped channel steels, with their notches facing outward to facilitate assembly operations such as installing bolts. Two first fixing holes 13 are formed in the lower end of the upper channel steel and the upper end of the lower channel steel, respectively. The base 1 also includes a plurality of second connecting members (not shown in the figure), which are simultaneously inserted into the first fixing holes 13 of the two channel steels to secure the two channel steels. The two channel steels are then reinforced by welding to form the first support portion 10.

[0052] The second support portion 20 is formed by stacking two equal-shaped channel steels, with their notches facing outward to facilitate assembly operations such as installing bolts. Two second fixing holes (not shown) are formed in the lower end of the upper channel steel and the upper end of the lower channel steel, respectively. A second connecting member is inserted through the second fixing holes of both channel steels to secure the two channel steels. The two channel steels are then reinforced by welding to form the second support portion 20.

[0053] It should be understood that the number of the second connecting members matches the sum of the number of the first fixing holes 13 and the second fixing holes, and the second connecting members can be the same as or different from the first connecting members. In this embodiment, the second connecting members are screws. In other optional embodiments, the second connecting members can be bolts, expansion bolts, rod-shaped structures, etc.

[0054] like Figure 4 As shown, in some embodiments, the connecting portion 30 is also made of channel steel, with the notch facing downward and the upper end surface flush with the upper end surfaces of the first support portion 10 and the second support portion 20 .

[0055] In some other optional embodiments, the first support portion 10 and / or the second support portion 20 and / or the connecting portion 30 may also be made of steel materials of other structures such as I-beams, box-shaped steels, etc.

[0056] The present invention also constructs a DCS control system, which includes a cabinet and any one of the above-mentioned bases 1, wherein the cabinet is detachably mounted on the base 1. The structure of the base 1 facilitates wiring of the cabinet.

[0057] Specifically, the cabinet is cuboid-shaped, with a rectangular lower end. Mounting holes are formed at each of the four corners of the lower end for removable connection to the base 1. A group of any two mounting holes symmetric about the long axis of the rectangle is defined as a single group. Thus, the cabinet includes two groups of mounting holes (not shown). Each group of mounting holes in the base 1 mates with two mounting holes (i.e., one group of mounting holes) located along the same length of the cabinet.

[0058] In some embodiments, the DCS control system includes at least two cabinets and at least three bases 1, wherein the two cabinets are arranged adjacent to each other, and two bases 1 are evenly spaced apart and disposed beneath the two cabinets to support the two cabinets. The upper ends of the two supporting portions of the bases 1 are each formed with two connection holes spaced apart, forming two groups of connection holes. Each group of connection holes is adapted to mate with two mounting holes (i.e., any one group of mounting holes) located at the same length of the cabinet.

[0059] The two assembly hole groups of one of the cabinets are now defined as the first assembly hole group and the second assembly hole group, and the two assembly hole groups of the other cabinet are defined as the third assembly hole group and the fourth assembly hole group, wherein the first assembly hole group is located on the side of the second assembly hole group away from the third assembly hole group, and the fourth assembly hole group is located on the side of the third assembly hole group away from the second assembly hole group.

[0060] The two groups of connection holes on the first base 1 among the three bases 1 correspond to the four adjacent assembly holes of the two cabinets (i.e., the second assembly hole group and the third assembly hole group), respectively; one group of connection holes on the second base 1 corresponds to the remaining two assembly holes of one of the cabinets (i.e., the first assembly hole group); and one group of connection holes on the third base 1 corresponds to the remaining two assembly holes of the other cabinet (i.e., the fourth assembly hole group).

[0061] By setting the base 1, the cabinet can be set as a structure separate from the base 1, and the base 1 consumes less material and does not need to completely cover the bottom of the cabinet. The empty space is convenient for wiring the cabinet, and it is easy to install and flexible to use.

[0062] It should be understood that when multiple cabinets need to be deployed, it is only necessary to add bases 1 simultaneously with the addition of cabinets. For example, four bases 1 are required to deploy three cabinets, five bases 1 are required to deploy four cabinets, and so on.

[0063] The present invention will be further described below with a specific embodiment:

[0064] In this embodiment, the dimensions of the cabinet are 2200mm high, 900mm long, and 400mm wide. The mounting holes on the four corners are positioned so that the distance between two mounting holes in the resulting mounting hole group is 310mm, and the distances between the two mounting hole groups and the adjacent short sides of the cabinet bottom are 75mm and 75mm, respectively.

[0065] The dimensions of the first supporting portion 10 / the second supporting portion 20 of the base 1 are 200 mm high * 300 mm long * 50 mm wide, and the dimensions of the connecting portion 30 are 50 mm high * 260 mm long * 50 mm wide.

[0066] It should be understood that since there is a hollow height of 17 cm between the bottom surface of the room where the cabinet is installed and the tiles, the base 1 is set to a height of 200 mm. After the installation is completed, there can be a height difference of 3 cm between the bottom of the cabinet and the tiles, and the tiles will not block the opening and closing of the cabinet door.

[0067] The distance between the first connection hole 11 and the second connection hole 21 in any connection hole group is 310 mm, the distance between two first connection holes 11 / two second connection holes 21 is 150 mm, and the major axis length of the first connection hole 11 / second connection hole 21 is 50 mm.

[0068] The diameter of the assembly hole of the cabinet and the short axis length of the first connecting hole 11 / the second connecting hole 21 are both 14 mm, the diameter of the first mounting hole 12 / the second mounting hole is 12 mm, and the diameter of the first fixing hole 13 / the second fixing hole is 12 mm.

[0069] The specification of the collision bolt used to fix the base 1 on the mounting platform and passed through the first mounting hole 12 / the second mounting hole is M12*100.

[0070] It is understandable that the above embodiments merely represent preferred implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features, make various variations, and improve upon them without departing from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, any equivalent transformations and modifications made within the scope of the present invention's claims should fall within the scope of the present invention's claims.
