[0034] In order to facilitate understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the utility model are shown in the drawings.

[0035] In the description of the embodiments of the utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0036] Furthermore, the terms "first" and "second" 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] like Figures 1 to 10 As shown, in one embodiment, an intelligent safety protection distribution cabinet 1 includes a busbar 10 and a main switch 20. The busbar 10 and the main switch 20 are electrically connected. The cabinet also includes a cabinet body 30, a protection component 40, and a linkage component. The protection component 40 includes a support base, a locking block 42, a clamping block 43, a push block 44, a control component, and a first elastic element 46. The support base is mounted on the cabinet body 30, the control component is mounted on the support base and is close to the busbar 10, the locking block 42 is mounted on the control component, and the push block 44 and the clamping block 43 are slidably mounted on the support base. The push block 44 is slidably engaged with the clamping block 43 and the locking block 42 respectively. The end of the clamping block 43 away from the push block 44 is engaged with the main switch 20. The first elastic element 46 is sleeved on the support base. On the seat, the first elastic element 46 pushes the support seat and the push block 44 respectively. When the temperature of the busbar 10 rises, the control element drives the locking block 42 away from the push block 44, so that the first elastic element 46 pushes the push block 44 closer to the clamping block 43, thereby causing the clamping block 43 to close the main power switch 20. The linkage component includes a cabinet door 51, a vertical block 52, a pull rod 53, and a second elastic element 54. The cabinet door 51 is rotatably mounted on the cabinet body 30. The vertical block 52 is mounted on the support seat. The pull rod 53 passes through the vertical block 52, and one end of the pull rod 53 is slidably engaged with the locking block 42. The other end of the pull rod 53 abuts against the cabinet door 51. The second elastic element 54 is sleeved on the pull rod 53. The second elastic element 54 pushes the pull rod 53 to drive the locking block 42 to slide away from the push block 44.

[0039] It should be noted that the busbar 10 and the main switch 20 are arranged in the cabinet 30, and the main switch 20 is a structure with a push rod. The support seat includes a support frame 410 and a control box 411, the support frame 410 spans the two ends of the cabinet 30 from one side of the push rod of the main switch 20, the control box 411 is arranged on one end of the support frame 410, and one side of the control box 411 extends to the outer side wall of the cabinet 30, so that a cavity is formed in the control box 411 and communicates with the outside of the cabinet 30. Further, the control member includes a temperature sensor 451, a controller 452 and an electromagnetic valve 453, for example, the temperature sensor 451 is an infrared temperature sensor, the controller 452 is a PLC, and the electromagnetic valve 453 is a direct push type electromagnetic valve 453. The controller 452 is arranged in the control box 411, the temperature sensor 451 is arranged on the outer side wall of the control box 411, and the sensing end of the temperature sensor 451 is close to the busbar 10 and does not contact the busbar 10. Further, the clamping block 42 is located in the control box 411, and the clamping block 42 is arranged on the output shaft of the electromagnetic valve 453, so that the electromagnetic valve 453 can drive the clamping block 42 to slide relative to the control box 411.

[0040] It needs to be explained that one side of the push block 44 is provided with a sliding rail extending from one end to the other end of the push block 44. The support frame 410 is provided with a sliding groove extending from one end to the other end of the support frame 410. The sliding rail and the sliding groove are clamped, so that the push block 44 can slide on the support frame 410. Further, one end of the push block 44 is provided with a sliding column 440 extending into the control box 411 and clamped with the clamping block 42. Specifically, one end of the push block 44 is provided with a sliding column 440, and the end of the sliding column 440 away from the push block 44 is provided with a clamping groove 4401 on the circumferential surface of the sliding column 440, and the width of the clamping groove 4401 is consistent with the thickness of the clamping block 42, so that the clamping block 42 can be clamped into the clamping groove 4401. Since the clamping block 42 is located in the control box 411, when sliding horizontally into the control box 411, the electromagnetic valve 453 can drive the clamping to be clamped into the clamping groove 4401 perpendicular to the sliding direction of the sliding column 440, so that the push block 44 cannot drive the sliding column 440 away from the control box 411, thereby keeping the push block 44 close to the control box 411. The clamping block 43 is vertically slidingly arranged on the support frame 410, one end of the clamping block 43 is clamped with the end of the push block 44 away from the clamping block 42, and the other end of the clamping block 43 is clamped with the push rod on the main power switch 20. Further, the end of the push block 44 away from the clamping block 43 is provided with two column grooves, and the two column grooves are respectively located on both sides of the sliding column 440. The control box 411 is provided with two guide columns, and the two guide columns respectively extend into the two column grooves, so that the push block 44 can slide stably on the support frame 410. Further, the first elastic member 46 is provided with two, and the two first elastic members 46 are respectively sleeved on the two guide columns, and the two first elastic members 46 respectively push the outer side wall of the control box 411 and the end of the push block 44. The two first elastic members 46 and the second elastic member 54 are both spring structures. In this way, when the sliding column 440 and the clamping block 42 are disengaged, the first elastic member 46 will push the push block 44 close to the clamping block 43, so that the clamping block 43 pulls the push rod on the main power switch 20 to disconnect the circuit.

[0041] As shown in Figures 1 to 2 , Figures 5 to 7 , in an embodiment, the other end of the push block 44 is provided with an inclined hole 441 clamped with the clamping block 43. The other end of the clamping block 43 is provided with a clamping groove clamped with the main power switch 20.

[0042] It should be noted that the inclined hole 441 extends from one end of the push block 44 to the other end, and the extension direction of the inclined hole 441 and any side of the push block 44 has an included angle, so that the inclined hole 441 is inclined to the two ends of the push block 44 respectively. Further, the push block 44 is also provided with a through hole, the through hole penetrates the two sides of the push block 44, and the through hole is vertically communicated with the inclined hole 441. Further, the clamping block 43 tends to be a T-shaped structure, one end of the clamping block 43 is provided with a protrusion 431, the clamping block 43 drives the protrusion 431 to pass through the through hole so that the protrusion 431 is clamped with the inclined hole 441. Further, a clamping groove is formed on the end of the clamping block 43 away from the protrusion 431, the clamping groove is sleeved on the push rod of the main switch 20, so that the inclined hole 441 is inclined from top to bottom and close to the direction of the slide column 440, and the clamping block 43 is vertically sliding on the support frame 410, when the first elastic member 46 pushes the push block 44 to slide horizontally along the support frame 410, the push block 44 pushes the protrusion 431 to slide downward along the inner side wall of the inclined hole 441, thereby driving the clamping groove on the end of the clamping block 43 away from the protrusion 431 to pull down the main switch 20 to disconnect the circuit, so as to avoid the continuous current overload of the busbar 10 leading to the continuous temperature rise, and causing the occurrence of safety accidents.

[0043] As shown in Figures 1 to 2 , Figures 5 to 6 , in an embodiment, the support seat further comprises a vertical block 412, the vertical block 412 is arranged on the support frame 410, and the clamping block 43 is slidingly arranged on the vertical block 412.

[0044] It should be noted that the vertical block 412 is arranged on the support frame 410, a straight groove is formed on the vertical block 412, the straight groove penetrates the upper and lower ends of the vertical block 412, and the formation direction of the straight groove is perpendicular to the formation direction of the sliding groove, a straight rail is arranged on the clamping block 43, and the straight rail is directed to the protrusion 431, when the straight rail is clamped with the straight groove, the clamping block 43 can slide up and down relative to the vertical block 412, thereby making the clamping block 43 slide vertically relative to the support frame 410, so that when the first elastic member 46 pushes the push block 44 to be close to the clamping block 43, the protrusion 431 slides along the inner side wall of the inclined hole 441, thereby making the clamping block 43 drive the clamping groove to pull down or pull up the push rod of the main switch 20, to realize physical power-off.

[0045] As shown in Figure 1 , Figure 3 , in an embodiment, the protection assembly 40 further comprises a warning light 47, the warning light 47 is arranged on the cabinet 30, and the warning light 47 is electrically connected with the controller 452.

[0046] It should be noted that when the temperature of the busbar 10 is abnormal, the operator can timely find the abnormality through the warning light 47, so as to improve the processing efficiency of the abnormality.

[0047] AsFigures 4 to 5 、 Figure 10 As shown in FIG. 42, in an embodiment, the clamping block 42 is provided with a first clamping hole 420 and a second clamping hole 421, and the first clamping hole 420 and the second clamping hole 421 have an included angle. The output shaft of the electromagnetic valve 453 is clamped with the first clamping hole 420, and the pull rod 53 is clamped with the second clamping hole 421.

[0048] It should be noted that the clamping block 42 is a right-angled structure with three adjacent sides. For the convenience of description, the three sides of the clamping block 42 are defined as a first side 422, a second side 423, and a third side 424. One end of the first side 422 is connected with one end of the second side 423, and the first side 422 and the second side 423 form a right angle. The third side 424 is arranged on the same end surface of the first side 422 and the second side 423, and the third side 424 forms a right angle with the first side 422 and the second side 423. Further, the first clamping hole 420 and the second clamping hole 421 are both waist-shaped hole structures. The first clamping hole 420 is arranged on the first side 422 and extends from one end of the first side 422 to the end close to the second side 423. The second clamping hole 421 is arranged on the second side 423 and extends from one end of the second side 423 to the end close to the first side 422. Further, the output shaft of the electromagnetic valve 453 is clamped with the first clamping hole 420 in the axial direction, and one end of the pull rod 53 is clamped with the second clamping hole 421 in the axial direction. Since the electromagnetic valve 453 is a straight push type electromagnetic valve 453, when the clamping block 42 is axially slid by the electromagnetic valve 453, the end of the third side 424 away from the end of the first side 422 is clamped with the clamping groove 4401 on the slide column 440, and the end of the pull rod 53 is slid along the arrangement direction of the second clamping hole 421.

[0049] In an embodiment, when the temperature of the busbar 10 is detected to be abnormal by the temperature sensor 451, the controller 452 sends a signal to the electromagnetic valve 453 to drive the clamping block 42 to slide axially, so that the clamping block 42 slides out axially relative to the clamping groove 4401 to be disengaged, and the end of the pull rod 53 is slid along the arrangement direction of the second clamping hole 421, so that the slide column 440 can slide out of the control box 411 to pull the main switch 20 to open the circuit.

[0050] In an embodiment, the other end of the pull rod 53 abuts against the cabinet door 51. When the cabinet door 51 is opened, the second elastic member 54 pushes the pull rod 53 away from the control box 411, so that the pull rod 53 drives the clamping block 42 to slide axially along the second clamping hole 421, and the output shaft of the electromagnetic valve 453 slides along the arrangement direction of the first clamping hole 420, so that the clamping block 42 slides out transversely relative to the clamping groove 4401 to be disengaged,

[0051] As shown in FIG. 42, in an embodiment, the clamping block 42 is provided with a first clamping hole 420 and a second clamping hole 421, and the first clamping hole 420 and the second clamping hole 421 have an included angle. The output shaft of the electromagnetic valve 453 is clamped with the first clamping hole 420, and the pull rod 53 is clamped with the second clamping hole 421. Figures 3 to 4 ,Figure 6 As shown in the figure, in an embodiment, the linkage assembly includes a cabinet door 51, a vertical block 52, a pull rod 53, and a second elastic member 54. The cabinet door 51 is rotationally arranged on the cabinet body 30. The vertical block 52 is arranged on the support seat. The pull rod 53 is arranged on the vertical block 52. One end of the pull rod 53 is slidably connected with the clamping block 42. The other end of the pull rod 53 is abutted with the cabinet door 51. The second elastic member 54 is sleeved on the pull rod 53. The second elastic member 54 pushes the pull rod 53 to drive the clamping block 42 to slide away from the push block 44.

[0052] It should be noted that the vertical block 52 is provided with a plurality of vertical blocks 52. Each vertical block 52 is arranged on the inner bottom wall of the control box 411. A through hole capable of passing through the pull rod 53 is formed on each vertical block 52. In this way, the pull rod 53 can be coaxially slid on each vertical block 52. One end of the pull rod 53 can be connected with the second clamping hole 421 on the clamping block 42. The other end of the pull rod 53 passes through the control box 411 and the cabinet body 30 to abut with the cabinet door 51. Further, the pull rod 53 is provided with a top ring 531. The diameter of the top ring 531 is greater than the diameter of the pull rod 53. The second elastic member 54 is sleeved on the pull rod 53. The two ends of the second elastic member 54 are respectively abutted with the vertical block 52 and the top ring 531. In this way, the second elastic member 54 pushes the pull rod 53 to slide out from one end of the cabinet door 51. When the cabinet door 51 is closed, the cabinet door 51 pushes the pull rod 53 away from the one end of the clamping block 42 to press the second elastic member 54. In this way, the pull rod 53 drives the clamping block 42 to be connected with the clamping groove 4401.

[0053] As shown in the figure, Figures 3 to 4 , Figure 6 In an embodiment, the linkage assembly further includes a limiting block 55. The limiting block 55 is arranged in the control box 411. The limiting block 55 is used to abut with the clamping block 42.

[0054] It should be noted that the limiting block 55 is arranged in the control box 411. The limiting block 55 is located on the one end of the clamping block 42 away from the pull rod 53. The one side of the limiting block 55 close to the clamping block 42 is parallel to the extension direction of the output shaft of the electromagnetic valve 453. In this way, when the electromagnetic valve 453 drives the clamping block 42 to be close to or away from the clamping groove 4401, the one end of the third side 424 away from the second side 423 can slide along the side of the limiting block 55. In this way, the clamping block 42 can be axially slid to be close to the clamping groove 4401.

[0055] Thus, by installing sensors and other monitoring components at locations within the distribution cabinet that require monitoring, and electrically connecting them to the controller 452, the system can simultaneously illuminate the warning light 47 and disconnect the main power switch 20 when an abnormality occurs in the distribution cabinet, thereby increasing protection and safety. Furthermore, one end of the pull rod 53 engages with the latch 42, and the other end abuts against the cabinet door 51. Therefore, when the cabinet door 51 is opened, the second elastic element 54 pushes the pull rod 53, causing the latch 42 to disengage from the latch slot 4401, allowing the clamp 43 to pull the main power switch 20 to disconnect the circuit. This ensures automatic power disconnection when an abnormality occurs in the distribution cabinet without affecting the opening of the cabinet door 51. Even when the distribution cabinet is not malfunctioning, opening the cabinet door 51 by maintenance personnel will also automatically disconnect the power, preventing maintenance personnel from forgetting to disconnect the main power switch 20 during maintenance work and avoiding the risk of electric shock from contacting internal electrical components while the power is on. This enhances safety and reliability.

[0056] It should be noted that the side of the control box 411 away from the push block 44 extends to the outer side of the cabinet 30, and the control box 411 is provided with a door. This allows maintenance personnel to directly debug and install the control components from outside the cabinet 30, avoiding operation in the narrow space inside the cabinet 30, thus improving the convenience of maintenance.

[0057] like Figures 1 to 2 , Figures 5 to 7 As shown, in one embodiment, the protection component 40 further includes a reset lever 48.

[0058] It should be noted that a clearance groove is provided on the vertical block 412, and the reset rod 48 is set on the protrusion 431 and extends out of the clearance groove. When the locking block 42 disengages from and engages with the locking groove 4401, the protrusion 431 is located at the end of the inclined hole 441 near the support frame 410, and at this time the push rod of the main power switch 20 is also facing the same direction. Thus, after the maintenance personnel have completed the repair, they push the reset rod 48 upward to drive the locking groove on the clamping block 43 to push the push rod on the main power switch 20, so that the main power switch 20 is restored to the energized state, and the sliding column 440 drives the locking groove 4401 to extend into the control box 411. When the maintenance personnel close the cabinet door 51, the cabinet door 51 can squeeze the pull rod 53, so that the pull rod 53 drives the locking block 42 to engage laterally with the locking groove 4401, thereby returning to the initial state.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
