It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figures 1 to 4 , the figure shows the preferred structure of the electrical protection device in this embodiment. As shown in the figure, the electrical protection device includes: a box body 1, a sliding door 2 and a protection mechanism 3. Among them, the side wall of one side of the box body 1 is provided with an opening, and the sliding door 2 can be opened and closed at the opening to close the opening, or to make the opening open. In order to facilitate pulling the sliding door 2, a handle 14 is provided on the sliding door 2.

[0022] The protection mechanism 3 is disposed in the box body 1 , and is used to accommodate the electronic component 4 and protect the electronic component 4 to prevent dust from falling on the electronic component 4 .

[0023] It can be seen that in this embodiment, an opening is provided on one side of the box body 1, and the sliding door 2 is openably arranged at the opening. The protection mechanism 3 protects the electronic components 4 to prevent dust from falling on the electronic components 4, thereby effectively avoiding the electronic components 4 from being affected by dust, and solving the problem in the prior art that electronic components are easily affected by dust after use.

[0024] See also Figures 1 to 4 In the above embodiment, the protection mechanism 3 includes: a mounting plate 31, a receiving plate 32, a shielding plate 33 and a moving mechanism 34. The mounting plate 31 is horizontally arranged in the box body 1, the mounting plate 31 is parallel to the bottom wall of the box body 1, and there is a preset distance between the mounting plate 31 and the bottom wall of the box body 1. The preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0025] The mounting plate 31 is provided with a through hole 311, which penetrates the mounting plate 31 along the thickness direction of the mounting plate 31. Specifically, the through hole 311 can be rectangular, circular or other shapes, and this embodiment does not impose any restrictions on this. In this embodiment, the through hole 311 is rectangular. Preferably, the through hole 311 is opened in the middle of the mounting plate 31.

[0026] The accommodating plate 32 corresponds to the through-hole 311, and the accommodating plate 32 is movably arranged in the through-hole 311, that is, the accommodating plate 32 moves in the through-hole 311, and moves toward the bottom wall ( Figure 2 The lower wall shown is the bottom wall), and the accommodating plate 32 is used to carry the electronic components 4. Specifically, the accommodating plate 32 is moved toward the top wall ( Figure 2 A receiving groove is provided on one side of the upper wall (the upper wall shown is the bottom wall), and the electronic component 4 is placed in the receiving groove. Preferably, the size of the receiving groove corresponds to the size of the electronic component 4, and the receiving groove positions the electronic component 4.

[0027] The moving mechanism 34 is connected to both the accommodating plate 32 and the shielding plate 33. The moving mechanism 34 is used to drive the accommodating plate 32 to move from the through-hole 311 to the bottom wall of the box body 1 until the electronic component 4 is placed below the mounting plate 31. While driving the accommodating plate 32 to move, the moving mechanism 34 also drives the shielding plate 33 to move, so that the shielding plate 33 moves to the through-hole 311, thereby covering the through-hole 311. Specifically, when the electronic component 4 follows the accommodating plate 32 to move to the bottom of the mounting plate 31, the electronic component 4 still corresponds to the through-hole 311. The moving mechanism 34 drives the accommodating plate 32 to move while driving the shielding plate 33 to move. In this way, when the electronic component 4 is placed under the mounting plate 31, the shielding plate 33 just corresponds to the through-opening 311. Although the electronic component 4 still corresponds to the through-opening 311, the shielding plate 33 can cover the through-opening 311, that is, cover the top of the electronic component 4, so that the electronic component 4 is completely placed under the protection of the mounting plate 31 and the shielding plate 33 to prevent dust from falling on the electronic component 4.

[0028] See also Figures 1 to 4 The moving mechanism 34 includes: a cylinder 341, two driving cylinders 342 and two transmission mechanisms. Among them, the top of the cylinder 341 is open, and the bottom can be in an open state or a closed state. The cylinder 341 is arranged on the bottom wall of the box body 1, that is, the bottom of the cylinder 341 is connected to the bottom wall of the box body 1, and the top of the cylinder 341 is connected to the mounting plate 31, then the cylinder 341 is completely placed under the mounting plate 31. In addition, the opening at the top of the cylinder 341 corresponds to the through-hole 311, then the interior of the cylinder 341 is connected to the interior of the through-hole 311, and the accommodating plate 32 is movably placed in the cylinder 341.

[0029] In a specific implementation, in order to adapt to the shape of the through-hole 311 , the cross-section of the cylinder 341 may be rectangular. Moreover, the cross-sectional dimensions inside the cylinder 341 match the cross-sectional dimensions of the through-hole 311 .

[0030] During specific implementation, the height of the cylinder 341 should ensure that the electronic component 4 can be completely placed in the cylinder 341 . This embodiment does not impose any limitation on the specific value of the height of the cylinder 341 .

[0031] The two transmission mechanisms are respectively arranged on two opposite sides of the cylinder 341, and both transmission mechanisms are connected to the receiving plate 32. Specifically, the positions of the two transmission mechanisms correspond to each other.

[0032] The two drive cylinders 342 are respectively arranged on two opposite side walls of the box body 1, and the two drive cylinders 342 are connected to the two transmission mechanisms in a one-to-one correspondence. Specifically, the positions of the two drive cylinders 342 correspond to the positions of the two transmission mechanisms, and one drive cylinder 342 is connected to one transmission mechanism. Each drive cylinder 342 is used to drive the receiving plate 32 to move into the cylinder body 341 through the corresponding transmission mechanism. The two drive cylinders 342 simultaneously drive the two transmission mechanisms to move, and then synchronously drive the receiving plate 32 to move from the through-hole 311 into the cylinder body 341, so as to drive the electronic component 4 to move into the cylinder body 341. When the electronic component 4 is not in use, the receiving plate 32 moves to the bottom of the cylinder body 341 (i.e. Figure 2 The electronic component 4 is placed in the cylinder 341. When the electronic component 4 needs to be operated, the receiving plate 32 moves toward the through opening 311, and the electronic component 4 is removed from the cylinder 341. Specifically, each driving cylinder 342 can be a hydraulic cylinder.

[0033] Each transmission mechanism includes: a first slider 343, a second slider 344 and a connecting rod 345. The top surface of the mounting plate 31 is provided with a first slide groove 312 that penetrates the mounting plate 31. The first slide groove 312 extends from a position close to the through opening 311 to a corresponding side wall of the box body 1. The first slide groove 312 has a preset length (the length direction of the first slide groove 312 is Figure 3 The preset length can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. The first slider 343 is slidably disposed in the first slide groove 312, and the first slider 343 is connected to the corresponding drive cylinder 342. Specifically, the top of the first slider 343 ( Figure 3 The upper part shown in the figure protrudes from the first slide groove 312, and the top of the first slider 343 is placed above the mounting plate 31, the driving cylinder 342 is arranged on the side wall of the box body 1 and is also placed above the mounting plate 31, and the top of the first slider 343 is connected to the driving end of the driving cylinder 342.

[0034] The side wall of the cylinder 341 is provided with a second slide groove 3411 at a position corresponding to the first slide groove 312. The position of the second slide groove 3411 corresponds to the position of the first slide groove 312. The second slide groove 3411 penetrates the side wall of the cylinder 341, and the second slide groove 3411 is arranged along the height direction ( Figure 3The second slide groove 3411 extends from the top of the cylinder 341 to the bottom of the cylinder 341. The second slider 344 is slidably disposed in the second slide groove 3411, and the second slider 344 is connected to the receiving plate 32. Specifically, one side of the second slider 344 protrudes from the second slide groove 3411 and extends toward the inside of the cylinder 341, and the receiving plate 32 is placed in the cylinder 341 and connected to the protruding side of the second slider 344.

[0035] One end of the connecting rod 345 is rotatably connected to the first slider 343, and the other end of the connecting rod 345 is rotatably connected to the second slider 344. Specifically, the connecting rod 345 is connected to the first slider 343 through a bearing, and the connecting rod 345 is also connected to the second slider 344 through a bearing.

[0036] In a specific implementation, the first sliding groove 312 and the second sliding groove 3411 may both be rectangular.

[0037] In a specific implementation, a first connecting groove 10 of a preset length is formed on the top surface of the mounting plate 31, and a first communicating groove 11 penetrating the mounting plate 31 is formed at the bottom of the first connecting groove 10. The first communicating groove 11 is connected to the first connecting groove 10, and the length direction of the first communicating groove 11 is consistent with the length direction of the first connecting groove 10. The first connecting groove 10 and the first communicating groove 11 form a first sliding groove 312, and the first sliding block 343 is slidably connected to the first connecting groove 10.

[0038] The outer wall of the cylinder 341 is provided with a second connecting groove 13 extending in the height direction of the cylinder 341 at a position corresponding to the first connecting groove 11, and a second connecting groove 12 penetrating the side wall of the cylinder 341 is provided on the side of the second connecting groove 13 close to the inside of the cylinder, the second connecting groove 13 is connected to the second connecting groove 12, and the extension direction of the second connecting groove 13 is consistent with the extension direction of the second connecting groove 12. The second connecting groove 12 and the second connecting groove 13 form a second slide groove 3411, and the second slider 344 is slidably connected to the second connecting groove 12. The first end of the connecting rod 345 is rotatably connected to the first slider 343, the connecting rod 345 is movably arranged in the first connecting groove 11 and the second connecting groove 13 in turn, and the second end of the connecting rod 345 is rotatably connected to the second slider 344.

[0039] See also Figures 2 to 4 There are two shielding plates 33 , and both shielding plates 33 are placed above the mounting plate 31 .

[0040] The two first sliders 343 correspond to the two shielding plates 33 one by one, and each first slider 343 partially protrudes from the corresponding first slide groove 312, and the protruding portion of each first slider 343 is connected to the corresponding shielding plate 33. When each first slider 343 slides along the corresponding first slide groove 312, it drives the corresponding shielding plate 33 to move. In this way, when the accommodating plate 32 moves toward the bottom of the cylinder 341, the two first sliders 343 slide relatively along their respective first slide grooves 312, thereby driving the two shielding plates 33 to move relatively and then dock. After docking, the two shielding plates 33 just cover the through-hole 311.

[0041] It can be seen that in this embodiment, the structure of the moving mechanism 34 is simple and easy to implement.

[0042] See also Figures 2 to 4 In the above embodiments, the protection mechanism 3 further includes: a limiting mechanism. The limiting mechanism is arranged on the receiving plate 32, and is used to limit the electronic component 4 so that the electronic component 4 is stably placed on the receiving plate 32, thereby preventing the electronic component 4 from shaking or shifting when following the movement of the receiving plate 32.

[0043] The limiting mechanism includes two limiting components, both of which are arranged on the receiving plate 32 and are respectively placed on both sides of the electronic component 4 , and the two limiting components work together to clamp and limit the electronic component 4 to ensure that the electronic component 4 is stably placed on the receiving plate 32 .

[0044] Baffles 6 are provided on both opposite sides of the accommodating plate 32 , so the accommodating plate 32 and the two baffles 6 form a substantially U-shape. The height of the baffles 6 can be determined according to actual conditions, and this embodiment does not impose any limitation on this.

[0045] The two limiting components correspond to the two baffles 6 one by one, and each limiting component is arranged between the baffle 6 on the corresponding side and the corresponding side of the electronic component 4 .

[0046] Each limit assembly includes: a clamping plate 5 and at least one clamping spring. The first end of each clamping spring is connected to the baffle 6 on the corresponding side, and the second end of each clamping spring is connected to the clamping plate 5, and the clamping plate 5 contacts the corresponding side of the electronic component 4. Each clamping spring is in a compressed state, and each clamping spring is used to push the corresponding clamping plate 5 to move toward the electronic component 4 under the action of the elastic restoring force. In this way, the two clamping plates 5 move toward the electronic component 4 respectively under the action of each clamping spring, so that the two clamping plates 5 clamp the electronic component 4.

[0047] In a specific implementation, each clamping spring is arranged at intervals on the baffle 6 on the corresponding side, and is preferably evenly distributed.

[0048] See also Figure 1 The electrical protection device further includes: a control panel 7. The control panel 7 is disposed on the sliding door 2, and the control panel 7 is electrically connected to the moving mechanism 34. The control panel 7 is used to control the moving mechanism 34 to drive the accommodating plate 32 and the shielding plate 33 to move. Specifically, the control panel 7 is electrically connected to the two driving cylinders 342, and the control panel 7 simultaneously controls the two driving cylinders 342 to drive the accommodating plate 32 and the two shielding plates 33 to move. In a specific implementation, the control panel 7 can be a PLC control panel.

[0049] See also Figures 2 to 4 In each of the above embodiments, the electrical protection device further includes: a plurality of brushes 8. Each brush 8 is disposed on the side wall of the through-port 311, and each brush 8 is in contact with the outer wall of the electronic component 4, so that each brush 8 cleans the electronic component 4. Specifically, when the through-port 311 is rectangular, each brush 8 is disposed on the four inner side walls of the through-port 311, and each brush 8 on each inner side wall is disposed at intervals, preferably evenly distributed. In this way, when the accommodating plate 32 drives the electronic component 4 to move toward the bottom of the cylinder 341, each brush 8 cleans the dust on the outer wall of the moving electronic component 4 to ensure that the electronic component 4 is clean and tidy.

[0050] See also Figures 2 to 4 In the above embodiments, the electrical protection device further comprises: a cooling mechanism 9. The cooling mechanism 9 is arranged in the box 1, and is used to cool the electronic component 4.

[0051] The cooling mechanism 9 includes: a motor 91, a rotating shaft 92 and a plurality of blades 93. The motor 91 is arranged on the top wall of the housing 1, and the motor 91 corresponds to the through-opening 311. The driving end of the motor 91 is connected to the first end of the rotating shaft 92, and the second end of the rotating shaft 92 extends to the bottom wall of the housing 1 and is placed above the through-opening 311. The blades 93 are arranged at intervals at the second end of the rotating shaft 92, and the blades 93 are placed above the electronic component 4. When the electronic component 4 operates normally, the motor 91 drives the blades 93 to rotate, thereby dissipating heat and cooling the electronic component 4.

[0052] See also Figures 1 to 4The use process of the electrical protection device is introduced as follows: in the initial state, the receiving plate 32 is placed at the top of the cylinder 341, and the electronic component 4 is located in the through-opening 311. The control panel 7 drives the two driving cylinders 342 to move at the same time, and each driving cylinder 342 drives the corresponding first slider 343 to slide in the first slide groove 312, and the two first sliders 343 slide towards the through-opening 311 relatively, so that the two first sliders 343 are relatively close. When each first slider 343 slides in the first slide groove 312 toward the through-opening 311, the sliding of the first slider 343 drives the movement of the connecting rod 345, so that the second end of the connecting rod 345 pushes the second slider 344 to slide along the second slide groove 3411 toward the bottom of the cylinder 341, and the two second sliders 344 slide synchronously toward the bottom of the cylinder 341, driving the receiving plate 32 and the electronic component 4 thereon to move toward the bottom of the cylinder 341 together, so that the electronic component 4 moves from the through-opening 311 to the inside of the cylinder 341. When the first slider 343 slides in the first slide groove 312, the sliding of the first slider 343 drives the movement of the shielding plate 33, and the relative approach of the two first sliders 343 drives the two shielding plates 33 to be relatively close and then docked. When the electronic component 4 is completely placed inside the cylinder 341, the two shielding plates 33 are just docked together, and the two shielding plates 33 after docking just correspond to the through-hole 311 to cover the through-hole 311, that is, to cover the top of the electronic component 4. In the process of the electronic component 4 moving into the cylinder 341, the brushes 8 at the through-hole 311 clean the electronic component 4, and can clean the dust on the outer wall of the electronic component 4.

[0053] In specific implementation, the size of the two shielding plates 22 after docking is greater than or equal to the cross-sectional size of the through opening 311, so that the two shielding plates 22 cover the through opening 311 after docking. The moving distance of the two first sliders 343 should ensure that the electronic component 4 is completely placed inside the cylinder 341 and that the two shielding plates 22 are in contact with each other. This embodiment does not impose any restrictions on the value of the moving distance of the two first sliders 343.

[0054] In summary, in this embodiment, an opening is provided on one side of the box body 1, and the sliding door 2 is openably arranged at the opening. The protection mechanism 3 protects the electronic component 4 to prevent dust from falling on the electronic component 4, thereby effectively preventing the electronic component 4 from being affected by dust.
