[0029] Example 1:

[0030] Please see Figure 1-6 This utility model provides a technical solution: a temporary power distribution box for construction sites with a safety protection mechanism, including a mobile mounting frame 1, a safety protection mechanism 2 on the top of the mobile mounting frame 1, a power distribution box 3 on the top of the mobile mounting frame 1, a dustproof net replacement mechanism 4 on the top of the mobile mounting frame 1, and a ventilation and heat dissipation mechanism 5 on the top of the mobile mounting frame 1.

A threaded handle 22 is threadedly connected to one side of the first fixed frame 21, and a rotating rod assembly 23 is rotatably connected to one side of the first fixed frame 21. A sliding groove plate assembly 24 is slidably connected to the bottom of the first fixed frame 21, and a fixed plate assembly 25 is slidably connected to the bottom of the first fixed frame 21 to prevent non-construction personnel from contacting it and reduce safety hazards.

[0033] Furthermore, the dustproof net replacement mechanism 4 includes a dustproof net 41, which is set on the top of the movable mounting frame 1 and the bottom of the distribution box 3. A second fixing frame 42 is fixedly connected to the bottom inside the distribution box 3. A slide cylinder 43 is fixedly connected to one end of the second fixing frame 42 near the dustproof net 41. A pull rod 44 is slidably connected inside the slide cylinder 43. A spring 45 is fixedly connected inside the slide cylinder 43.

[0034] Furthermore, the rotating rod assembly 23 is slidably connected to the slide plate assembly 24, the rotating rod assembly 23 is rotatably connected to the fixed plate assembly 25, the threaded handle 22 is threadedly connected to the fixed plate assembly 25, and the slide plate assembly 24, the fixed plate assembly 25 and the movable mounting frame 1 are slidably connected, which can quickly provide safety protection.

[0035] Example 2:

[0036] Please see Figure 7-8 Furthermore, in conjunction with Embodiment 1, the heat dissipation component 51 includes a motor 511, which is disposed on the top of the movable mounting bracket 1. The motor 511 is fixedly connected to the outside of the distribution box 3. A worm gear 512 is fixedly connected to the output end of the motor 511. A third fixing bracket 513 is fixedly connected inside the distribution box 3. A worm wheel 514 is rotatably connected to the bottom of the third fixing bracket 513. A fan blade 515 is fixedly connected to the bottom of the worm wheel 514, which can dissipate heat from the distribution box 3 and prevent high temperature from causing circuit failure.

[0037] Furthermore, the ventilation assembly 52 includes a push rod housing 521, which is disposed on the top of the movable mounting bracket 1 and fixedly connected to the inside of the distribution box 3. A push rod 522 is slidably connected inside the push rod housing 521, and a rotating plate 523 is rotatably connected inside the push rod 522. A connecting plate 524 is fixedly connected inside the rotating plate 523, and a louver 525 is rotatably connected to one side of the connecting plate 524. A fixed slider 526 is slidably connected inside the push rod housing 521, and a handle 527 is rotatably connected to the outside of the push rod housing 521. A first bevel gear 528 is fixedly connected to one end of the handle 527 near the inside of the push rod housing 521, and a second bevel gear 529 is rotatably connected inside the push rod housing 521. A threaded rod 5210 is fixedly connected to one end of the second bevel gear 529 near the fixed slider 526. This ventilation system ventilates the distribution box 3 and prevents internal moisture from causing circuit malfunctions.

[0038] Furthermore, there are two sets of worm gears 514 symmetrically distributed around the worm 512, and they mesh with the worm 512. There are also two sets of fan blades 515 symmetrically distributed around the worm 512, which can dissipate heat evenly.

[0039] Furthermore, multiple sets of louvers 525 are equidistantly distributed on one side of the distribution box 3 and are rotatably connected to the distribution box 3. The first bevel gear 528 and the second bevel gear 529 are meshed together. The push rod 522, the fixed slider 526 and the threaded rod 5210 are threaded together, which can control the ventilation opening for ventilation.

[0040] In actual operation, when this device is used, first place the distribution box 3 on top of the mobile mounting frame 1, then pull the fixing plate assembly 25 so that the sliding plate assembly 24 and the fixing plate assembly 25 slide on top of the mobile mounting frame 1. At the same time, the rotating rod assembly 23 extends. When the fixing plate assembly 25 reaches the side of the first fixing frame 21 near the threaded handle 22, fix the fixing plate assembly 25 and the first fixing frame 21 with the threaded handle 22, and then push the mobile mounting frame 1 to the required construction location. When used for a long time, dust will accumulate inside the distribution box 3, which may affect the circuit. Pull the pull rod 44 to make it slide upward in the sliding cylinder 43 and the slot 46, while the spring 45 retracts. When the pull rod 44 moves to the top of the sliding cylinder 43, rotate the pull rod 44 to make it lock into the top of the sliding cylinder 43, and then remove and replace the dust screen 41 for cleaning to prevent dust accumulation. When the distribution box 3 has been used for a long time, high temperatures may be generated inside. By starting the motor 511, the worm gear 512 is rotated, which in turn drives the worm wheel 514 to rotate, further causing the fan blades 515 to rotate, thus blowing air to cool the distribution box 3. At the same time, turning the handle 527 causes the first bevel gear 528 to rotate, which in turn drives the second bevel gear 529 to rotate. At this time, the threaded rod 5210 rotates, causing the fixed slider 526 and the push rod 522 to slide downwards, further pulling the rotating plate 523 to move the connecting plate 524 downwards, thereby causing the louvers 525 to rotate and ventilate and dissipate heat inside the distribution box 3.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
