[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of an arc flash protection device provided in one embodiment of the present invention, comprising:

[0029] The main control device 1 has a display section and an operation section at its upper and lower ends, respectively.

[0030] Upper protective cover 2 and lower protective cover 3 are arranged in an array on the front side of the main control device 1 to protect the upper and lower ends of the main control device 1.

[0031] Upper protrusion 4 and lower protrusion 5 are respectively located at the bottom and top of the upper protective cover 2 and the lower protective cover 3;

[0032] The lifting structure is symmetrically arranged on the left and right sides of the lower protrusion 5;

[0033] The snap-fit ​​structure is symmetrically arranged on the left and right sides of the upper protrusion 4. The inner end of the snap-fit ​​structure is movably snapped into the surface of the main control device 1, and the front end of the snap-fit ​​structure is correspondingly arranged with the lifting structure.

[0034] In this embodiment of the utility model, when in use, pressing the lifting structure on both sides of the lower protrusion 5 causes the locking structure to separate from the main control device 1, thereby allowing the upper protective cover 2 and the lower protective cover 3 to be opened.

[0035] By setting an upper protective cover 2 and a lower protective cover 3 at the upper and lower ends of the main control device 1 respectively, the display part and the operation part of the main control device 1 are prevented from being contaminated and are easy to clean. The lower protective cover 3 can be opened alone or in conjunction with the upper protective cover 2 as needed, so as to operate and view.

[0036] like Figure 4 and Figure 5 As shown, in a preferred embodiment of this utility model, the main control device 1 array is opened at the bottom of the through hole 14. A movable sealing structure is provided below the main control device 1. The movable sealing structure includes a rotating cylinder 15, a lifting ring plate 16, a hinge rod 18, and a movable sealing plate 19. The rotating cylinder 15 array is rotatably and slidably installed at the bottom of the main control device 1. The lifting ring plate 16 is spirally installed on the inner side of the rotating cylinder 15, and a hinge groove 17 is opened on the inner circumferential array. The movable sealing plate 19 is circumferentially hinged to the bottom of the main control device 1 to seal the through hole 14. The hinge rod 18 is movably hinged to the bottom end of the hinge groove 17 and is movably hinged to the bottom of the movable sealing plate 19.

[0037] In this embodiment of the utility model, when in use and when not in use, the rotating cylinder 15 at the bottom of the main control device 1 is rotated, which in turn drives the lifting ring plate 16 to move upward and drives the hinge rod 18 in the hinge groove 17 to move upward, thereby causing the movable sealing plate 19 below the edge of the through hole 14 to close and seal with each other.

[0038] By providing a movable sealing structure at the through hole 14 of the main control device 1, the through hole 14 at the bottom of the main control device 1 can be blocked, thereby sealing the main control device 1 and preventing foreign objects from entering the main control device 1.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the lifting structure includes a sliding top plate 8, a first movable groove 6, and a lifting top plate 7. The first movable groove 6 is symmetrically opened on the left and right sides of the lower protrusion 5. The sliding top plate 8 is slidably installed on the outer end of the first movable groove 6, and the lifting top plate 7 is slidably installed on the inner end of the first movable groove 6, with its top corresponding to the lower part of the front end of the snap-fit ​​structure.

[0040] In this embodiment of the utility model, when in use, by pressing the sliding top plates 8 on both sides of the lower protrusion 5 and moving them towards the center along the first movable groove 6, the lifting top plate 7 is pushed into the groove 11 at the lower end of the upper protrusion 4, thereby making the snap-fit ​​structure movable.

[0041] By setting up a lifting structure and linking it with a snap-fit ​​structure, it is easy to open the upper protective cover 2 and the lower protective cover 3 together or to open the lower protective cover 3 separately.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the snap-fit ​​structure includes a groove 11 and a guide rod 13. The surface of the main control device 1 is arrayed with slots 12. The grooves 11 are symmetrically opened at the bottom of the left and right sides of the upper protrusion 4 and are correspondingly arranged with the lifting structure. A lifting groove 9 is opened at the upper end of the upper protrusion 4 and the lower end of the main control device 1. The guide rod 13 is arrayed inside the lifting groove 9 and a lifting limit plate 10 is provided on its surface.

[0043] In this embodiment of the utility model, when the lifting structure is working, it will lift the lifting limit plate 10 inside the groove 11 upward, so that it moves upward along the lifting groove 9 and the guide rod 13, thereby separating its rear end from the slot 12 on the surface of the main control device 1, so that the upper protective cover 2 and the lower protective cover 3 can be opened at the same time, and then the main control device 1 can be operated.

[0044] like Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the hinge groove 17 is inclined, and the radius of the movable sealing plate 19 is greater than the radius of the through hole 14.

[0045] In this embodiment of the utility model, when in use, the hinge groove 17 is tilted to facilitate the movement of the hinge rod 18, and the radius of the movable sealing plate 19 is made larger than the radius of the through hole 14 to facilitate sealing.

[0046] like Figure 4 and Figure 5As shown, in a preferred embodiment of the present invention, the inner side of the sliding top plate 8 is provided with a slope corresponding to the lower end of the lifting top plate 7, and the weight of the sliding top plate 8 is less than the weight of the lifting top plate 7.

[0047] In this embodiment of the utility model, when in use, a ramp is provided on the inner side of the sliding top plate 8 corresponding to the lower end of the lifting top plate 7, which facilitates lifting. By making the weight of the sliding top plate 8 less than the weight of the lifting top plate 7, the sliding top plate 8 will be pressed outward by the lifting top plate 7 when released.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the rear end of the lifting limit plate 10 is movably engaged with the slot 12, and the bottom of the front end of the lifting limit plate 10 is inserted into the inside of the groove 11.

[0049] In this embodiment of the utility model, when in use, the rear end of the lifting limit plate 10 is movably engaged with the slot 12, and then the bottom of the front end of the lifting limit plate 10 is inserted into the inside of the groove 11. Thus, when the lifting top plate 7 moves into the groove 11, it will lift the lifting limit plate 10 and separate it from the slot 12.

[0050] The above embodiments of this utility model provide an arc light protection device. When it is necessary to operate the operation part at the lower end of the main control device 1, the lower protrusion 5 is pulled to open the lower protective cover 3, thereby facilitating operation.

[0051] When you want to open the upper protective cover 2, you can press the sliding top plate 8 on both sides of the lower protrusion 5 and move it towards the middle along the first movable groove 6. Then, the lifting top plate 7 is pushed into the groove 11 at the lower end of the upper protrusion 4, thereby lifting the lifting limit plate 10 inside the lifting groove 9 upward, so that its rear end is separated from the slot 12 on the surface of the main control device 1. This allows the upper protective cover 2 and the lower protective cover 3 to be opened at the same time, and then the display part at the upper end of the main control device 1 can be operated.

[0052] When not in use, rotating the rotating cylinder 15 at the bottom of the main control device 1 moves the lifting ring plate 16 upward, which in turn moves the hinge rod 18 in the hinge groove 17 upward. This causes the movable sealing plates 19 below the edge of the through hole 14 to close together, thereby sealing the through hole 14 at the bottom of the main control device 1 and preventing foreign objects from entering the main control device 1.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
