[0025] Reference Figure 1-4A protective device for electrical equipment includes a connecting frame 1, which is configured with a "U"-shaped structure. Two movable wheels 2 are rotatably connected to the surface of the connecting frame 1. A pull rod 4 is fixedly installed on the top of the connecting frame 1. A support plate 5 is slidably connected to the surface of the pull rod 4. A baffle 6 is fixedly installed on the surface of the support plate 5. Two side rods 9 are provided on the surface of the support plate 5. A first screw 7 is movably passed through the surface of each side rod 9. An extension rod is fixedly installed at the end of the first screw 7. A rotating sleeve 8 is threadedly connected to the surface of the first screw 7. A drive mechanism for moving the support plate 5 is provided inside the pull rod 4. During use, when the electrical box needs to be moved, it can be placed on the support plate 5. The support plate 5 can be raised and lowered under the action of the drive mechanism. Therefore, even when moving the electrical box from a truck or... The electrical box is relatively easy to move from the ground to the truck. It can be directly supported by the pallet 5. If water accumulates on the ground, it can be raised at any time. The pallet 5 is also equipped with a baffle 6, side bars 9 and a first screw 7, which makes it easy to fix the electrical box on the pallet 5 from four sides, providing protection and reducing the possibility of the electrical box falling and getting damaged. In use, simply place the electrical box on the pallet 5, bring the two side bars 9 close to each other, rotate the first screw 7 to keep the extension rod at the end of the first screw 7 horizontal, and move the extension rod to contact the electrical box. Hold the first screw 7 still and rotate the rotating sleeve 8. This allows the first screw 7 and the extension rod to press the electrical box against the baffle 6, thus fixing and protecting the electrical box.

[0026] Furthermore, the drive mechanism includes a third screw 15. A vertical groove is provided on the side wall of the pull rod 4. The third screw 15 is rotatably connected inside the vertical groove. The third screw 15 is threaded through the support plate 5. A worm gear 14 is fixedly installed on the surface of the third screw 15 near the top. A worm 13 is rotatably connected inside the pull rod 4. The worm 13 and the worm gear 14 mesh. A crank 12 is fixedly installed at the end of the worm 13. In use, the crank 12 is manually turned, which drives the worm 13 to rotate. The worm 13 drives the worm gear 14 to rotate, and the worm gear 14 drives the third screw 15 to rotate. The third screw 15 drives the support plate 5 to move on the pull rod 4, thereby facilitating the lifting and lowering of the support plate 5.

[0027] Furthermore, the surface of the support plate 5 is provided with an elongated groove, and two side rods 9 are slidably connected inside the elongated groove. A second screw 10 is rotatably connected inside the elongated groove. The second screw 10 is provided with two opposite threads with its midpoint as the dividing line. The two side rods 9 are respectively threaded to the two ends of the second screw 10. The two side rods 9 can move relative to each other by means of the second screw 10. In actual use, the second screw 10 can be directly rotated so that the two side rods 9 can be moved in the elongated groove by means of the two threads on the surface of the second screw 10.

[0028] Furthermore, rollers 11 are evenly rotatably connected to the surface of the tray 5. By setting the rollers 11, the power box is placed on the tray 5 and supported by the rollers 11. Thus, the rotation of the rollers 11 makes it easy to move the power box onto the tray 5 and also easy to move it off the tray 5.

[0029] Furthermore, threaded holes are provided on both sides of the connecting frame 1, and bolts 3 are threadedly connected inside the threaded holes. The surface of the movable wheel 2 is provided with round holes for the bolts 3 to be inserted. By setting the bolts 3, when it is necessary to use components such as the support plate 5 and the connecting frame 1 as support for the power box, the bolts 3 can be inserted into the round holes of the movable wheel 2 to fix the movable wheel 2, thereby improving the stability during placement and enhancing the protective effect. When it is not necessary to fix the movable wheel 2, the bolts 3 can simply be pulled out of the round holes.

[0030] Furthermore, support feet are provided at the bottom of both ends of the connecting frame 1. The distance between the two arms of the connecting frame 1 is greater than the length of the tray 5, which makes it easy for the tray 5 to be lowered directly to the ground. The support feet are designed to work with the casters 2 to keep the connecting frame 1 in a horizontal position.

[0031] In summary, when the power box needs to be moved, it can be placed on the pallet 5. The pallet 5 can be raised and lowered by the drive mechanism, making it relatively easy to move the power box from the truck or from the ground to the truck. The power box can be directly supported by the pallet 5. If there is water accumulation on the ground, it can be raised at any time. The pallet 5 is also equipped with a baffle 6, side rods 9, and a first screw 7, which facilitates the fixing of the power box on the pallet 5 from four sides, providing protection and reducing the possibility of the power box falling and getting damaged. During use, simply place the power box on the pallet 5, bring the two side rods 9 close together, rotate the first screw 7 to keep the extension rod at the end of the first screw 7 horizontal, and move the extension rod to contact the power box. Then, hold the first screw 7 still and rotate the rotating sleeve 8, which allows the first screw 7 and the extension rod to press the power box against the baffle 6, achieving a fixed and protective function. During use, the drive mechanism is manually operated by turning the crank handle 12. The crank handle 12 drives the worm gear 13 to rotate, which in turn drives the worm wheel 14 to rotate. The worm wheel 14 then drives the third screw 15 to rotate, which in turn drives the support plate 5 to move on the pull rod 4, thus facilitating the lifting and lowering of the support plate 5. The two side rods 9 move relative to each other using the second screw 10. In actual use, simply rotate the second screw 10 so that it drives the two side rods 9 to move in the long slot using the two sections of threads on its surface. By setting up rollers 11, the power box is placed on the support plate 5 and supported by the rollers 11. The rotation of the roller 11 allows the power box to be easily moved onto the tray 5 and also easily moved off the tray 5. By setting bolts 3, when the tray 5 and connecting frame 1 are needed as supports for the power box, the bolts 3 can be inserted into the round holes of the moving wheel 2 to fix the moving wheel 2, thereby improving the stability during placement and enhancing the protective effect. When it is not necessary to fix the moving wheel 2, the bolts 3 can simply be pulled out of the round holes. The support feet are designed to cooperate with the moving wheel 2 to keep the connecting frame 1 in a horizontal state.
