Description

Technical Field

[0001] This utility model relates to the field of electrical protection device technology, specifically to an electrical protection box. Background Technology

[0002] As a critical protective device during the operation of electrical equipment, the main function of an electrical protection box is to provide physical protection for electrical components during normal operation, isolating them from interference from adverse external factors. Simultaneously, in the event of electrical faults or other abnormal situations, it facilitates quick inspection and maintenance of the electrical system by personnel, ensuring the stable operation of the electrical equipment. Traditional electrical protection boxes typically consist of a box body and a door panel. The door panel is hinged to one side of the frame opening on the front of the box body. This structure meets basic protection and maintenance needs in daily operation, allowing personnel to manually open the door panel directly to replace internal electrical components.

[0003] However, traditional electrical protection boxes lack a means of remotely opening the door via physical means. When a short circuit or overload occurs inside the box, leading to a fire, the fire generates a large amount of heat, causing the surrounding temperature to rise rapidly and posing a risk of electrical leakage. In such situations, workers cannot approach the box directly to open the door, making it difficult to extinguish the fire on the internal electrical components. Additional tools are needed to open the door. This inability to open the door promptly delays the optimal time for firefighting, potentially allowing the fire to spread, further damaging the electrical equipment, and even causing more serious safety accidents, resulting in significant economic losses and the risk of personal injury.

[0004] Therefore, there is an urgent need to design an electrical protection box that can open the door from a distance to extinguish fires on the electrical components inside the box in a timely manner. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical protection box that can remotely open its door in emergency situations, especially in dangerous scenarios such as short circuits or overloads causing fires inside the box, so as to promptly extinguish fires and perform other emergency treatments on the internal electrical components.

[0006] The technical solution adopted by this utility model to solve the above problems is: an electrical protection box, including a box body and a door panel, wherein the door panel is hinged to one side of the frame opening on the front side of the box body by a hinge, and further includes a release component for opening the door panel remotely, wherein the release component includes a door support unit and a drive unit for driving the door support unit to open the door panel.

[0007] The door support unit includes a door support plate, a connecting rod, and a hinge seat. The door support plate is fixedly installed on the inside of the door panel. One end of the connecting rod is hinged to the door frame, and the other end is slidably hinged to the door support plate through the hinge seat.

[0008] The drive unit includes a slide block, a slider, and a pulling component. The slide block is fixedly installed on the outside of the door panel, the slider is slidably installed inside the slide block, the hinge seat is rotatably connected to the slide block, and the pulling component is used to drive the slider to slide along the slide block towards the end closer to the hinge.

[0009] Preferably, the pulling component includes a rope and a handle, with one end of the rope fixedly connected to the slider and the other end connected to the handle.

[0010] Preferably, the rope adapter is equipped with a guide assembly, which includes a bending guide sleeve fixed to the outside of the door panel and a movable guide sleeve disposed at the bottom of the box. The bending guide sleeve includes two sets of rigid sections respectively disposed on the outside of the door panel and the outside of the box, and a flexible section disposed between the two sets of rigid sections. The flexible section is disposed on the outside of the hinge part between the door panel and the box. The movable guide sleeve includes a fixed section fixedly disposed in the box and a movable section rotatably disposed at the lower end of the fixed section.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] Example:

[0026] See Figure 1 - Figure 4 In this embodiment, an electrical protection box is provided to provide stable and reliable protection for electrical components during the operation of electrical equipment. In emergency situations, especially when a short circuit or overload occurs inside the electrical protection box, leading to a fire, the door panel 12 can be opened remotely to promptly extinguish fires and perform other emergency treatments on the internal electrical components, thereby effectively improving the safety of electrical equipment operation and the practicality of the electrical protection box.

[0027] The electrical protection box specifically includes a box body 11 and a door panel 12. The door panel 12 is hinged to one side of the frame opening on the front side of the box body 11 via a hinge 13. It also includes a release assembly 14 for opening the door panel 12 remotely. Based on the traditional structure, a release assembly 14 is added. The release assembly 14 includes a door support unit 15 and a drive unit 16 that drives the door support unit 15 to open the door panel 12.

[0028] The door support unit 15 includes a door support plate 17, a connecting rod 18, and a hinge seat 19. The door support plate 17 is fixedly disposed on the inner side of the door panel 12. One end of the connecting rod 18 is hinged to the door frame 20, and the other end is slidably hinged to the door support plate 17 via the hinge seat 19. When the drive unit 16 is working, the door support unit 15 can generate a thrust that opens the door panel 12 under the coordinated action of the connecting rod 18, the door support plate 17, and the hinge seat 19, thereby realizing the opening action of the door panel 12.

[0029] The drive unit 16 includes a slide block 21, a slider 22, and a pulling component 23. The slide block 21 is fixedly disposed on the outside of the door panel 12, the slider 22 is slidably disposed inside the slide block 21, and the hinge seat 19 is rotatably connected to the slide block 21. The pulling component 23 is used to drive the slider 22 to slide along the slide block 21 towards the end closer to the hinge 13. When the door panel 12 is closed, the slider 22 and the hinge seat 19 are located at the furthest position away from the hinge 13. The pulling component 23 drives the slider 22 to move the hinge seat 19 synchronously. The two ends of the connecting rod 18 are respectively hinged to the door frame 20 and the hinge seat 19. Since the length of the connecting rod 18 is fixed, when the hinge seat 19 at one end slides along the end of the door support plate 17 near the hinge 13, the connecting rod 18 swings outward along the hinge point with the door frame 20, thereby driving the door panel 12 to open outward as well.

[0030] In practical use, when a fire occurs due to a short circuit, overload, or other fault inside the electrical protection box, personnel do not need to approach the box. They can simply maintain a safe distance and use the pulling component 23 to drive the slider 22 within the slide block 21, causing the connecting rod 18 to swing and thus opening the door panel 12. This allows personnel to quickly open the door panel 12, promptly extinguish the fire on the internal electrical components, prevent the fire from spreading, minimize losses, and solve the problem mentioned in the background art of not being able to open the door panel 12 in an emergency.

[0031] In this embodiment, the hinge seat 19 includes a guide block 24, a bolt 25, and a nut 26. The slider 22 is fixedly provided with a bearing plate 27 that is adapted to the rotation of the bolt 25. The door support plate 17 is provided with a guide groove 28 that is adapted to the sliding of the guide block 24. The bolt 25 passes through the bearing plate 27, the guide block 24, and the connecting rod 18 from top to bottom, and its lower end is threadedly connected to the nut 26.

[0032] In this embodiment, the pulling component 23 includes a rope 29 and a handle 30. One end of the rope 29 is fixedly connected to the slider 22, and the other end is connected to the handle 30. In this embodiment, both the rope 29 and the handle 30 are made of fire-resistant and insulating materials (rope 29: aramid fiber, polyimide fiber; handle 30: insulating rubber). By pulling the handle 30, the rope 29 is pulled, which in turn drags the slider 22 along the slide block 21.

[0033] To ensure that the rope 29 can still smoothly transmit traction force when the electrical protection box catches fire, the rope 29 is equipped with a guide assembly 31 (made of fire-resistant and high-temperature resistant material), which includes a bending guide sleeve 32 fixed to the outside of the door panel 12 and a movable guide sleeve 33 disposed at the bottom of the box body 11. The bending guide sleeve 32 includes two sets of rigid sections 34 respectively disposed on the outside of the door panel 12 and the outside of the box body 11, and a flexible section 35 disposed between the two sets of rigid sections 34. The flexible section 35 is disposed on the outside of the hinge part between the door panel 12 and the box body 11 to adapt to the change of the opening angle of the door panel 12. The bending guide sleeve 32 can bend synchronously with the door panel 12 without obstruction throughout the entire process of the door panel 12 from closed to the maximum opening angle (about 90°). The movable guide sleeve 33 includes a fixed section 36 fixedly disposed inside the box body 11 and a movable section 37 rotatably disposed at the lower end of the fixed section 36. The movable section 37 can rotate horizontally around the lower end of the fixed section 36 when the rope 29 is pulled, so as to adapt to the tension in different directions. The lower end of the movable section 37 is provided with a flexible sleeve 38 to effectively prevent the rope 29 from wearing out.

[0034] See Figure 5 The bottom of the enclosure 11 is detachably connected to a base plate 41. The base plate 41 has mounting holes 42 for fixing the movable guide sleeve 33, and the fixing section 36 is fixedly inserted into the mounting holes 42. Before the electrical protection box is inspected and repaired, the base plate 41 and the movable guide sleeve 33 can be removed from the bottom of the enclosure 11 to reduce the interference of the movable guide sleeve 33 on the replacement of electrical components inside the enclosure 11.

[0035] To further optimize the performance of the guide assembly 31, the guide assembly 31 also includes a limiting component 43 disposed between the bent guide sleeve 32 and the movable guide sleeve 33, see [link to relevant documentation]. Figure 6 and Figure 7 It includes an outer shell 44 connected to the bending guide sleeve 32 and the movable guide sleeve 33. A pair of guide wheels 45 are rotatably disposed inside the outer shell 44, and the rope 29 is disposed between the two sets of guide wheels 45. In this embodiment, the guide wheels 45 are provided with annular grooves 46 so that the rope 29 can pass through. During the pulling process, the rope 29 slides along the annular grooves 46, cooperating with the rotation of the guide wheels 45 to reduce friction.

[0036] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
