[0079] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0080] The following Figures 1 to 16 , describes the embodiments of the present invention.

[0081] According to an embodiment of the present invention, on the one hand, a low-voltage power distribution cabinet for a power plant is provided, which includes a power distribution main body 1, which includes a cabinet body 1001 and a cover plate 1002. The cabinet body 1001 and the cover plate 1002 form a hollow rectangular structure, and the cover plate 1002 is provided at the top of the cabinet body 1001 and is connected by a hinge. A fixed frame body 3, which is arranged in a rectangular frame structure, and a hollow wire passing chamber 2 is formed between the outer sides of the two sides of it and the inner wall of the cabinet body 1001 for neatly routing cables.

[0082] The low-voltage power distribution cabinet for the power plant also includes;

[0083] A busbar assembly 4, which is provided with a plurality of them at equal intervals at the top of the fixed frame body 3, for example, it can be 3, 4, 5, etc., and the outer sides of it are respectively used for incoming line and wire passing work to complete the current closed-loop work inside the power distribution main body 1.

[0084] An assembly main body 5, which is arranged at equal intervals in the middle of the fixed frame body 3 for installing working equipment and wiring connection work. The working equipment at least includes an electrical component 8, a terminal block assembly 9, and a measuring unit.

[0085] The outside of the assembly main body 5 is provided with a disassembly and assembly mechanism for quickly installing with the fixed frame body 3. Under the action of an external force, the disassembly and assembly mechanism has a first position that moves away from the fixed frame body 3, separating the assembly main body 5 from the fixed frame body 3; and a second position that moves towards the fixed frame body 3, connecting the assembly main body 5 with the fixed frame body 3. In this embodiment, the external force can be human force or self-driven by a driving device. Of course, this embodiment is only an example for this, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0086] In this embodiment, by setting the assembly main body 5 and the disassembly and assembly mechanism, installation and power distribution can be directly carried out. Only need to quickly install the corresponding assembly main body 5 with the fixed frame body 3 through the disassembly and assembly mechanism to complete the quick installation work. After that, the cables can be uniformly threaded inside the wire threading chamber 2, and then the assembly work of the entire power distribution cabinet can be quickly completed. The operation is convenient and fast, and the installation efficiency is higher. During the whole process, it is not necessary for the staff to stand and operate for a long time. Moreover, according to the different numbers and heights of the electrical component 8, the terminal block component 9, and the measurement unit, the height of the assembly main body 5 can be flexibly adjusted, and the installation freedom is higher.

[0087] Furthermore, a plurality of assembly main bodies 5 are equidistantly arranged inside the fixed frame body 3. When assembling the entire power distribution cabinet, the installation and power distribution work of the electrical component 8, the terminal block component 9, and the measurement unit can be directly carried out inside each assembly main body 5 on the ground outside. During the whole process, the staff can directly sit on the ground and operate. Moreover, multiple staff can simultaneously carry out the installation and wiring work of different components, and there is no need to stand in one position for a long time to install a plurality of electrical components 8, terminal block components 9, and measurement units. Therefore, the phenomenon of discomfort during installation by the staff will not occur.

[0088] Furthermore, in an optional implementation manner, the disassembly and assembly mechanism includes an installation main body 6 and a limiting main body 7. The installation main body 6 is arranged on both sides of the assembly main body 5 and moves back and forth on both sides of the assembly main body 5 to complete the limiting and separating work with the limiting main body 7.

[0089] Specifically, under the action of an external force, the installation main body 6 moves towards the fixed frame body 3. After abutting against the limiting main body 7, it pushes one end of the limiting main body 7 to rotate, so that the other end of the limiting main body 7 is clamped with the installation main body 6;

[0090] Under the action of an external force, the mounting body 6 moves away from the fixed frame body 3. After being separated from the limiting body 7, the limiting body 7 resets, so that the other end of the limiting body 7 is separated from the mounting body 6.

[0091] Further, in an optional embodiment, the electrical component 8 at least includes a circuit breaker, a disconnector, a fuse, a contactor and a relay, which are used to ensure the safe and reliable transmission of electric energy to various electrical equipment, and the terminal block assembly 9 is used to connect and distribute electric energy.

[0092] This application provides a low-voltage power distribution cabinet for a power plant with a disassembly and assembly mechanism. Specifically, when assembling the power distribution cabinet, first, the entire assembly body 5 and the entire power distribution body 1 are separated from each other. Therefore, in the early stage, the staff can sit outside and install the electrical components 8, the terminal block assembly 9 and each electrical appliance on the measuring unit on the assembly body 5. The specific installation method is that installation slides are provided on the middle inner wall of the assembly body 5. By engaging the electrical component 8, the terminal block assembly 9 and the measuring unit with the installation slides, and then carrying out the wire threading work. After the electrical appliances on the entire assembly body 5 are installed, the assembly body 5 can be appropriately installed above the fixed frame body 3. When installing, it is necessary to control the limiting engagement between the mounting body 6 on the assembly body 5 and the limiting body 7 on the fixed frame body 3. After the engagement is completed, the assembly work is completed. After the assembly is completed, the main lines are wired and installed through the wire threading chamber 2, and the assembly of the entire power distribution cabinet is completed, which is convenient to operate.

[0093] Among them, according to Figure 3 As shown, the fixed frame body 3 includes 4 fixed vertical rods 31, and the 4 fixed vertical rods 31 are distributed in a rectangle. Two transverse connecting rods 33 are symmetrically installed at the front and rear positions of the tops of the 4 fixed vertical rods 31, and the transverse connecting rods 33 are welded to the fixed vertical rods 31;

[0094] Longitudinal connecting rods 32 are equidistantly arranged between the two front and rear symmetric fixed vertical rods 31. The inside of the longitudinal connecting rods 32 is set as a hollow structure, and a limiting body 7 is arranged inside the hollow structure. An assembled body 5 to be installed is arranged between the two left and right symmetric longitudinal connecting rods 32, and through holes 51 are evenly distributed on both side surfaces of the assembled body 5;

[0095] Specifically, by arranging the transverse connecting rods 33 up and down, the bottom of the 4 fixed vertical rods 31 can be supported. And due to the equidistant arrangement of the longitudinal connecting rods 32 and the limiting body 7 arranged inside them, the corresponding installation work can be carried out with the mounting body 6 on the assembly body 5, achieving the effect of flexibly adjusting the installation position of the assembly body 5 as required for replacement and use.

[0096] Further, in an alternative embodiment, the mounting body 6 includes a connecting spring 63, a connecting plate 62, a cross plate 61, a moving column 64, and a limiting block 65.

[0097] One end of the connecting spring 63 is connected to the inner wall of the assembly body 5, and the connecting plate 62 is connected to the other end of the connecting spring 63. The cross plate 61 is disposed on the connecting plate 62. The moving column 64 is disposed on the end surface of the cross plate 61 close to the assembly body 5 and extends in the direction close to the assembly body 5. A through hole 51 corresponding to the moving column 64 is formed in the assembly body 5 for the moving column 64 to pass through. The limiting block 65 is disposed on the moving column 64.

[0098] During the actual installation process, under the action of an external force, the cross plate 61 drives the moving column 64 to move in the direction close to the fixed frame 3, the connecting spring 63 is compressed, and after the moving column 64 abuts against the limiting body 7, one end of the limiting body 7 is pushed to rotate, so that the other end of the limiting body 7 is clamped with the limiting block 65.

[0099] After the external force disappears, under the elastic force of the connecting spring 63, the cross plate 61 drives the moving column 64 to move in the direction away from the fixed frame 3. After the moving column 64 is separated from the limiting body 7, the limiting body 7 resets, so that the other end of the limiting body 7 is separated from the limiting block 65.

[0100] Among them, according to Figures 3 to 8 As shown, when installing through the mounting body 6 and the limiting body 7, the mounting body 6 includes 3 cross plates 61 and 2 connecting plates 62, and the 3 cross plates 61 and 2 connecting plates 62 are arranged in a "king" - shaped structure. The top ends of the cross plates 61 are evenly distributed with moving columns 64 penetrating inside the through holes 51, and a connecting spring 63 is arranged between adjacent moving columns 64 and connected to the inner wall of the assembly body 5.

[0101] Specifically, the top end of the moving column 64 is horizontally arranged up and down, and a limiting block 65 is further arranged at the inner - side position of its top end. A reserved hole 66 penetrates through the surface of the connecting plate 62, and a bolt 67 is arranged inside the reserved hole 66 and connected to a threaded hole on the inner wall of the assembly body 5.

[0102] Further, in an alternative embodiment, the limiting body 7 includes a rotating cylinder 71, a trigger plate 72, and a limiting plate 73. The trigger plate 72 and the limiting plate 73 are distributed on the outer part of the rotating cylinder 71. A torsion spring 75 is arranged in the middle circular hole of the rotating cylinder 71 and connected to a fixed shaft rod 74. The front and rear top ends of the two sides of the fixed shaft rod 74 are connected to the front and rear top ends of the longitudinal connecting rod 32.

[0103] During the actual installation process, when the installation main body 6 moves towards the fixing frame body 3, after the installation main body 6 abuts against the trigger plate 72 and pushes the rotating cylinder 71 to rotate, the limiting plate 73 is clamped with the installation main body 6, and the torsion spring 75 is compressed.

[0104] When the installation main body 6 moves away from the fixing frame body 3, after the installation main body 6 is separated from the trigger plate 72, under the elastic force of the torsion spring 75, the rotating cylinder 71 resets, so that the limiting plate 73 is separated from the installation main body 6.

[0105] The specific installation process is as follows:

[0106] First of all, 2 workers are needed to assist in taking. One worker takes the entire assembly main body 5, and then the other worker takes the cross plates 61 on the left and right sides of the assembly main body 5, so that the cross plates 61 and the connecting plates 62 are pulled to move towards the middle of the assembly main body 5 under the action of the connecting spring 63. As a result, the cross plates 61 drive the moving columns 64 at their tops to move inwards. After that, the entire "U"-shaped assembly main body 5 can be clamped between the 2 longitudinal connecting rods 32. When reaching the corresponding position, at this time, the external worker releases the pulling of the cross plates 61, so that they are reset under the action of the connecting spring 63 and move outwards. When moving outwards, the moving columns 64 also move outwards. When the moving columns 64 move outwards, they will reach the hollow structure inside through the through holes on the surface of the longitudinal connecting rods 32. When moving, they will contact the trigger plate 72 on the limiting main body 7 in the hollow structure, and then push the trigger plate 72 to rotate around the rotating cylinder 71. When the rotating cylinder 71 rotates, it will drive the limiting plate 73 outside it to rotate. When the limiting plate 73 rotates to the lowest position, the top of it will be clamped into the gap between the limiting block 65 and the moving column 64, achieving the effect of clamping and limiting the position of the moving column 64. Thus, the preliminary work of determining the position of the assembly main body 5 is completed. At this time, the supporting worker can release the support of the assembly main body 5 and take the external bolt 67, so that it is threadedly connected between the reserved hole 66 and the threaded hole on the inner wall of the assembly main body 5, thereby completing the fixing work of the position of the assembly main body 5.

[0107] In this embodiment, when the assembly main body 5 needs to be disassembled, at this time, the bolt 67 is removed, and the inward pulling work of the cross plates 61 is repeated, so that the moving columns 64 do not squeeze the trigger plate 72. Thus, the rotating cylinder 71 will reset under the action of the torsion spring 75, and then the limiting plate 73 will not limit the limiting block 65, and finally the disassembly purpose is completed.

[0108] Further, in an alternative embodiment, according to Figures 10 - 12 As shown, the terminal block assembly 9 includes a plurality of terminal block bodies 91 arranged at equal intervals. A trigger switch 92 is provided on the surface of the terminal block body 91. A connection seat 93 is provided at the bottom of the terminal block body 91, and a hollow groove 931 is provided inside the connection seat 93. A locking assembly 95 is provided inside the hollow groove 931 and is connected to the identification assembly 94. The identification assembly 94 is used to identify the electrical equipment controlled by the outside world.

[0109] In this embodiment, the identification assembly 94 is locked by the locking assembly 95 inside the hollow groove 931. At the same time, a pushing assembly 10 is also provided inside the hollow groove 931. When the staff installs the identification assembly 94, only one press on the identification assembly 94 is required to complete the installation work with the locking assembly 95. When disassembly is required, only press the identification assembly 94 again to unlock it from the locking assembly 95, and then cooperate with the push of the pushing assembly 10 to complete the disassembly work of the identification assembly 94. The entire disassembly and installation process is very fast. Therefore, when the circuit changes, flexible adjustment work can be carried out, not only will there be no messy phenomenon, but the identification is clear, which is convenient for the subsequent staff to view, and also makes the environment inside the entire power distribution cabinet more concise.

[0110] Further, in an alternative embodiment, a pushing assembly 10 is also provided in the hollow groove 931 inside the connection seat 93 for pushing out the unlocked identification assembly 94.

[0111] Specifically, the pushing assembly 10 includes a push plate 101 and a return spring 102. A return spring 102 is provided on the back of the push plate 101 and is connected to the inner wall of the hollow groove 931.

[0112] The identification assembly 94 includes an identification plate 941, a mounting block 942, and a connecting block 943. The mounting block 942 is integrally installed on the back of the identification plate 941, and a connecting block 943 is provided on the outside of the mounting block 942. The position of the connecting block 943 corresponds to the position of the locking assembly 95, and the inner side of the connecting block 943 is arranged in an arc structure.

[0113] As Figure 11 and Figure 12 shown, the locking assembly 95 is arranged in rectangular holes on both sides and slightly inside the hollow groove 931. A fixing rod 951 is fixed in the middle of the rectangular hole. A fixing seat 952 is provided at the slightly inner position outside the fixing rod 951, and a movable seat 953 is provided at the slightly outer position. The movable seat 953 is connected to the fixing seat 952 by an intermediate spring 954.

[0114] Further, in an alternative embodiment, a first locking block 955 is integrally installed at the top end of the fixed seat 952, and the inner and outer sides of the top end of the first locking block 955 are both arranged in an arc structure. A second locking block 956 is integrally installed at the top end of the moving seat 953, and the outer top end of the second locking block 956 is arranged in a rectangular structure.

[0115] Specifically, first, when installing the identification component 94, it is necessary to pick up the identification component 94 and make it snap into the inner hollow groove 931 of the connecting seat 93. When the identification component 94 is snapped in, the mounting block 942 on the back of the identification plate 941 will drive the connecting block 943 to move inside the hollow groove 931. When it moves to the inner position, it will come into contact and snap with the first locking block 955. When the arc cross-sections of the two come into contact, the connecting block 943 will be snapped between the first locking block 955 and the second locking block 956. Thus, by limiting the connecting block 943, the installation of the entire identification plate 941 is completed.

[0116] When subsequent disassembly is required, at this time, the identification plate 941 can be continuously pressed, so that the connecting block 943 continues to be squeezed against the second locking block 956 and then reaches the inside of the second locking block 956. At this time, since a pushing component 10 is arranged inside the hollow groove 931, it will push the entire mounting block 942, and thus the entire identification component 94 is completely pushed out of the inside of the hollow groove 931 to complete the disassembly work.

[0117] In this embodiment, since the moving seat 953 can move outside the fixed rod 951, when the connecting block 943 completely reaches the inside of the second locking block 956, in cooperation with the pushing work of the pushing component 10, the second locking block 956 and the moving seat 953 will be pushed together to the position of the first locking block 955, and then they will be completely pushed out.

[0118] Among them, the pushing work of the pushing component 10 is that after the identification component 94 is installed, the return spring 102 is squeezed. When it is squeezed for disassembly again, the return spring 102 will be squeezed again. Thus, when the entire identification component 94 is not restricted by any force, at this time, the return spring 102 resets and drives the push plate 101 to completely push out the entire identification component 94.

[0119] Further, in an alternative embodiment, slide rail assemblies 12 are provided above the terminal block body 91 and at the bottom of the connecting seat 93. The slide rail assembly 12 includes a concave slide rail 122 and an arc-shaped limiting groove 121, and the arc-shaped limiting groove 121 is provided on the outer wall of the concave slide rail 122.

[0120] Further, in an alternative embodiment, a warning component 11 is provided outside the slide rail assembly 12 for performing operation warning work. The upper and lower positions of the warning component 11 are engaged with the slide rail assembly 12 above the terminal block body 91 and at the bottom of the connection base 93.

[0121] In this embodiment, the warning component 11 can move flexibly on the terminal block assembly 9. Therefore, when the external device is operating normally and the external operator is operating inside the power distribution cabinet, human error may occur. When the warning device is set at the switch position of the corresponding terminal block assembly 9, it can play a warning role for the operator to avoid the phenomenon of sudden stop and sudden start of the external working equipment.

[0122] Further, in an alternative embodiment, the warning component 11 includes a warning body 111 and a limiting component 112 on the warning body 111.

[0123] Specifically, the limiting component 112 includes a pressing block 1121, a connecting rod 1123, a compression spring 1122 and a protruding elastic piece 1124. The bottom of the pressing block 1121 is integrally installed with the connecting rod 1123, and a compression spring 1122 is arranged outside the connecting rod 1123 and connected to the through groove on the inner wall of the warning body 111. The lower part of the outer wall of the connecting rod 1123 is connected to the protruding elastic piece 1124.

[0124] A clamping hole corresponding to the position of the protruding elastic piece 1124 is provided on the warning body 111 for the protruding elastic piece 1124 to pass through and be engaged with the arc-shaped limiting groove 121.

[0125] Among them, when the external device corresponding to the terminal block is in the manual working state, in order to avoid human error inside the power distribution cabinet, at this time, the staff can squeeze the pressing block 1121, so that it drives the connecting rod 1123 to squeeze the compression spring 1122. Thus, the connecting rod 1123 drives the protruding elastic piece 1124 outside it to be received inside the warning body 111. Thus, the protruding elastic piece 1124 and the arc-shaped limiting groove 121 are separated from each other, and the warning body 111 can be pushed to slide on the concave slide rail 122. When it slides to the appropriate switch position of the terminal block assembly 9, release the squeeze on the pressing block 1121, and the compression spring 1122 will be reset, so that it drives the connecting rod 1123 to rise, and then drives the protruding elastic piece 1124 to protrude out of the clamping hole again and be engaged with the arc-shaped limiting groove 121 to complete the position fixing work and ensure that there will be no position deviation.
