Description

Technical Field

[0001] This utility model relates to the field of protection panel technology, and in particular to a cable-free retraction protection panel. Background Technology

[0002] Protection panels are primarily used to protect electrical equipment and power systems. They are cabinets that integrate multiple protection devices. Internally, they typically contain relays (such as current relays and voltage relays), monitoring and control devices, fuses, terminal blocks, communication management units, and other equipment. These devices can monitor and control parameters such as current, voltage, and frequency in the power system. For example, when an overcurrent occurs in a line, the current relay will quickly activate, cutting off the faulty line through the control circuit in the protection panel, thereby protecting the electrical equipment from damage.

[0003] Currently, when upgrading or replacing protection panels, the cables need to be removed from the electronic components inside the protection panel and then pulled out of the cable hole before the entire protection panel can be disassembled. This operation is too complicated, increases the workload of the staff, and the back-and-forth pulling of the cables will damage the cables, and safety cannot be guaranteed.

[0004] To address this issue, we proposed a cable-free retraction protection panel. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to provide a protective cabinet that will not damage the cable during disassembly.

[0006] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a cable-free retraction protection cabinet, which includes a cabinet shell, and includes a front cabinet door and a rear cabinet door disposed on the cabinet shell;

[0007] A detachable crossbeam, comprising a short beam and a detachable beam, is mounted on the bottom frame on one side of the rear cabinet door;

[0008] Clip-on assembly, which is mounted on the short beam and the disassembly beam.

[0009] In a preferred embodiment of the sludge sampling device of this utility model: a slot for embedding is provided at one end of the junction of the short beam and the disassembly beam, and a corresponding plug-in section is also provided at the junction of the disassembly beam.

[0010] In a preferred embodiment of the sludge sampling device of this utility model: the snap-fit ​​component includes a groove, a buckle, a through groove, and a reserved groove;

[0011] The outer side of the disassembly beam has a groove, and a buckle is provided inside the groove in a rotatable connection manner. The short beam has a through groove on the same side as the buckle for embedding the buckle. The side of the disassembly beam near the buckle also has a reserved groove that matches the through groove.

[0012] In a preferred embodiment of the sludge sampling device of this utility model: the buckle has an L-shaped structure, the size of the protrusion for embedding is adapted to the through groove and the reserved groove, and the outer side of the through groove is cut into an arc surface.

[0013] In a preferred embodiment of the sludge sampling device of this utility model: a limiting groove is provided on the inner wall of the cabinet shell near the disassembly beam.

[0014] In a preferred embodiment of the sludge sampling device of this utility model: a supporting beam is provided on the bottom frame of the cabinet shell near the front door.

[0015] In a preferred embodiment of the sludge sampling device of this utility model: a wire guide plate is detachably installed at the bottom of the cabinet housing.

[0016] In a preferred embodiment of the sludge sampling device of this utility model: a disassembly assembly is provided at the junction of the wiring plate and the cabinet housing.

[0017] In a preferred embodiment of the sludge sampling device of this utility model: the disassembly assembly includes a sliding plate, a slide rail, and a threaded hole;

[0018] The bottom outer side of the cabinet housing is equipped with a sliding plate for detachable connection with the cable tray, and the cable tray is also provided with matching slide rails on both sides.

[0019] The slide rail has several threaded holes arranged in a straight line, and the slide plate also has several matching threaded holes installed accordingly. Bolts are inserted into both sets of threaded holes.

[0020] In a preferred embodiment of the sludge sampling device of this utility model: two threading holes are symmetrically opened on the threading plate.

[0021] The beneficial effects of this utility model are as follows: the buckle is rotated outward from the reserved groove and through groove, so that the buckle is disengaged from the reserved groove and through groove, thereby releasing the self-locking state. Then, the disassembly beam is removed from the short beam, forming a notch on the cabinet housing. At the same time, the bolts are removed from the threaded holes on the slide plate and slide rail. After all the bolts are removed, the cabinet housing and the cable tray can be separated, and then the cabinet housing can be removed from the cable tray without damaging the cable bundle.

[0027] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0029] Reference Figures 1-4 A cable-free retraction protection cabinet is provided, including a cabinet housing 1, which includes a front cabinet door 11 and a rear cabinet door 12 disposed on the cabinet housing 1;

[0030] The detachable crossbeam 2, which includes a short beam 21 and a detachable beam 22, is located on the bottom frame on one side of the rear cabinet door 12;

[0031] The snap-fit ​​assembly 3 is mounted on the short beam 21 and the disassembly beam 22.

[0032] During use, when the staff disassembles the cabinet, the detachable beam 2 can be disassembled by unlocking the snap-fit ​​component 3. This separates the mechanical connection between the disassembly beam 22 and the short beam 21, enabling the rapid disassembly of the detachable beam 2. This creates a process gap of a specific size at the bottom of the side door frame of the rear cabinet door 12, effectively eliminating the movement interference path between the cable bundle and the cabinet housing 1. At this time, the cable bundle can be removed non-destructively along the preset direction through this gap. Simultaneously, the operator can use this process improvement to perform a low-resistance translation operation on the cabinet housing 1, ensuring the integrity of the cable system during the equipment removal stage.

[0033] During operation, staff can easily and promptly open the front cabinet door 11 to conduct a comprehensive inspection of the internal circuit system of the cabinet housing 1, ensuring that the circuit is functioning properly. Simultaneously, when it is necessary to drag the cabinet housing 1, the rear cabinet door 12 can be opened for removal.

[0034] Reference Figures 3-4 A slot 211 for embedding is provided at one end of the junction of the short beam 21 and the disassembly beam 22, and a corresponding plug-in section 221 is also provided at the junction of the disassembly beam 22.

[0035] During disassembly and assembly, workers insert the connector 221 of the disassembly beam 22 vertically into the slot 211 of the short beam 21. During insertion, constant attention must be paid to the fit to ensure a tight, gapless connection. Once inserted, a structurally stable, detachable beam 2 is assembled. This design not only makes disassembly more convenient and efficient, but also, in practical use, the tightly fitted components effectively enhance the overall connection rigidity of the cabinet housing 1, ensuring stable operation under complex working conditions.

[0036] Reference Figures 3-4 The snap-fit ​​component 3 includes a groove 31, a buckle 32, a through groove 33, and a reserved groove 34;

[0037] The outer side of the disassembly beam 22 is provided with a groove 31, and a buckle 32 is provided inside the groove 31 in a rotatable connection manner. The short beam 21 and the buckle 32 are provided with a through groove 33 for embedding the buckle 32. The side of the disassembly beam 22 near the buckle 32 is also provided with a reserved groove 34 that matches the through groove 33.

[0038] During assembly, the buckle 32 is rotated clockwise (based on the actual operating direction) to smoothly insert it into the through slot 33 of the short beam 21, and then further in until it passes through the through slot 33 and is securely embedded in the pre-reserved slot 34 on the plug-in section 221. At this point, the annular self-locking structure is complete. This ingenious connection method greatly enhances the stability of the connection between components, effectively improves the overall structural strength, and can better meet the mechanical requirements of various usage scenarios.

[0039] Simultaneously, based on the aforementioned principle, when disassembly is required, the operator rotates the buckle 32 outward from the reserved slot 34 and through slot 33, causing the buckle 32 to disengage from the limiting positions of the reserved slot 34 and through slot 33, successfully releasing the self-locking state. Subsequently, the buckle 32 is easily retracted into the groove 31, effectively reducing the space occupied by the buckle 32 in the non-connected state, facilitating subsequent operations and storage.

[0040] Reference Figure 3 The buckle 32 has an L-shaped structure, and the size of the protrusion used for embedding is adapted to the through groove 33 and the reserved groove 34. The outer side of the through groove 33 is cut into an arc surface.

[0041] The size of the protrusion into which the buckle 32 is embedded is equal to or slightly smaller than the size of the through groove 33 and the reserved groove 34, which can improve the fit of the embedding and allow the buckle 32 to be embedded tightly and securely, thereby improving the embedding quality. At the same time, the outer side of the through groove 33 is cut into an arc surface, which reduces the resistance during snapping and reduces the difficulty of operation.

[0042] Reference Figures 1-2 A limit groove is provided on the inner wall of the cabinet shell 1 near the disassembly beam 22.

[0043] The limiting slide and slot 211 are positioned correspondingly, and together they set a dedicated track for the movement trajectory of the disassembly beam 22, allowing it to move only in the vertical direction and effectively restricting displacement in other directions. This not only greatly facilitates the disassembly operation of the disassembly beam 22, but also allows workers to quickly and accurately complete the disassembly of the disassembly beam 22 when equipment maintenance or component replacement is required.

[0044] Moreover, during normal operation of the equipment, the close cooperation strengthens the connection between the detachable beam 2 and the cabinet housing 1. With the improvement of connection stability, the overall structural strength of the cabinet housing 1 is also significantly enhanced, which can better cope with various complex working conditions and external forces, and ensure the long-term stable operation of the equipment.

[0045] Reference Figures 1-2 A supporting beam 4 is provided on the bottom frame of the cabinet shell 1 near the front cabinet door 11.

[0046] The supporting beam 4 can significantly enhance the overall strength of the cabinet shell 1 and greatly improve its stability, so that the cabinet shell 1 can maintain good structural performance under various working conditions.

[0047] Reference Figures 1-2 The bottom of the cabinet shell 1 is detachably equipped with a cable tray 5.

[0048] Cable tray 5 is used to install and support cable bundles, and also serves to install internal equipment in the control panel.

[0049] Reference Figure 2 A disassembly assembly 6 is provided at the junction of the wiring board 5 and the cabinet housing 1.

[0050] The disassembly component 6 can disconnect the detachable connection between the wiring board 5 and the cabinet housing 1, allowing the cabinet housing 1 to be removed from the wiring board 5.

[0051] Reference Figure 2 The disassembly component 6 includes a slide plate 61, a slide rail 62, and a threaded hole 63;

[0052] A sliding plate 61 for detachable connection with the cable tray 5 is installed on the bottom of the outer side of the cabinet housing 1. Corresponding sliding tracks 62 are also provided on both sides of the cable tray 5.

[0053] The slide 62 has several threaded holes 63 arranged in a straight line, and the slide plate 61 also has several matching threaded holes 63 installed accordingly. Bolts are inserted into both sets of threaded holes 63.

[0054] When separating the panel housing 1 from the wiring board 5, the operator must first remove the bolts from the threaded holes 63 on the slide plate 61 and slide rail 62. After all the bolts are removed, the connection between the panel housing 1 and the wiring board 5 is released. Then, the panel housing 1 can be dragged to separate it from the wiring board 5.

[0055] Reference Figures 1-2 Two threading holes 51 are symmetrically opened on the threading plate 5.

[0056] The cable pass-through hole 51 is used to accommodate the cable bundle.

[0057] During use, the operator first rotates the buckle 32 outwards, away from the reserved slot 34 and through slot 33, thereby releasing the self-locking state. After completing this step, the fixing restriction of the disassembly beam 22 is released, and the operator can then remove the disassembly beam 22 from the short beam 21. At this time, a notch will be formed on the cabinet housing 1, creating conditions for subsequent operations.

[0058] Next, workers must use appropriate tools and follow the correct turning direction to remove the bolts one by one from the threaded holes 63 on the slide plate 61 and slide rail 62. When removing the bolts, ensure that all bolts are completely removed to avoid any omissions. After all bolts have been removed, the connection between the panel housing 1 and the wiring plate 5 is completely released, and workers can then separate the two.

[0059] Finally, when dragging the cabinet housing 1 outwards, the staff should maintain a uniform speed and steady movement to avoid damaging the cable bundle due to uneven force or directional deviation. This operating procedure not only allows for the smooth removal of the cabinet housing 1 from the cable tray 5 without damaging the cable bundle, but also makes the entire disassembly process simple and efficient, effectively improving work efficiency and reducing operational difficulty.

[0060] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
