[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 4 The utility model provides an embodiment: a floor-standing electric energy meter box, comprising a bottom plate 1, a supporting base 2 is fixedly connected to the bottom of the bottom plate 1 for supporting, and the electric energy meter box body 3 is lifted off the ground for a distance to prevent ground water from entering the interior of the electric energy meter box body 3 on rainy days, the top of the bottom plate 1 is fixedly connected to the electric energy meter box body 3, the top of the electric energy meter box body 3 is fixedly connected to the ceiling 4 for guiding the flow direction of rainwater, a mounting groove 6 is provided on the right side of the electric energy meter box body 3, the cross-section of the mounting groove 6 is set to a convex shape, and the side with a smaller opening faces the outside of the electric energy meter box body 3, a ventilation plate 5 for heat dissipation is installed on the inner wall of the mounting groove 6, a heat dissipation groove is provided on the surface of the ventilation plate 5, and a dustproof net is installed on the inner wall of the heat dissipation groove, a mounting mechanism is provided inside the ventilation plate 5, and a protective mechanism is provided on the right side of the electric energy meter box body 3.

[0034] Reference Figure 1 - Figure 4 The protective mechanism includes a rotating shaft 8, and the front and rear sides of the rotating shaft 8 are rotatably connected with fixed blocks 7. The fixed blocks 7 are fixedly installed on the left and right sides of the electric energy meter box body 3 to increase the stability of the rotating shaft 8 when it rotates. The rotating shaft 8 is elastically connected to the inner wall of the fixed block 7 through a torsion spring 9. The torsion spring 9 is set to make the rotating shaft 8 rotate to reel in the protective cloth 10. The circumferential surface of the rotating shaft 8 is fixedly connected with a protective cloth 10. The protective cloth 10 is set to be a waterproof cloth, which can prevent raindrops from splashing on rainy days and entering the interior of the electric energy meter box body 3 to play a protective role. The protective cloth 10 is wrapped around the circumferential surface of the rotating shaft 8, and the end of the protective cloth 10 away from the rotating shaft 8 is fixedly connected to a connecting block 11 arranged in a horizontal state. A positioning mechanism is arranged inside the connecting block 11, and a box door 21 is hinged on the front of the electric energy meter box body 3.

[0035] Reference Figure 4 , Figure 6The positioning mechanism includes an insertion rod 12, which passes through and is fixedly connected to the inner wall of the connecting block 11. A slot 13 matching the insertion rod 12 is opened on the right side of the power meter box body 3. The insertion rod 12 is plugged into the inner wall of the slot 13. The number of slots 13 is set to be multiple, and the multiple slots 13 are arranged in a straight line and equidistantly on the right side surface of the power meter box body 3. By inserting the insertion rod 12 into the slots 13 at different heights, the area of ​​the ventilation plate 5 covered by the protective cloth 10 can be controlled, thereby controlling the ventilation effect.

[0036] Reference Figure 4 - Figure 6 The positioning mechanism also includes a positioning rod 14, the number of which is set to be multiple, and an arc surface is set at one end of the multiple positioning rods 14 that are away from each other. The positioning rod 14 is slidably installed on the inner wall of the insertion rod 12, and the sliding direction of the positioning rod 14 is forward and backward sliding. The positioning rod 14 is elastically connected to the inner wall of the insertion rod 12 through a spring 15. By setting the spring 15, the multiple positioning rods 14 have a tendency to move away from each other. The slot 13 is provided with a positioning groove 16 matching the positioning rod 14 on the inner wall. The number of the positioning grooves 16 is set to be multiple, and the multiple positioning grooves 16 are arranged on the inner wall of the slot 13 at equal angles in a ring shape. When the positioning rod 14 is stuck in the interior of the positioning groove 16, the spring 15 acts to make the insertion rod 12 more firmly inserted into the interior of the slot 13, thereby improving the stability of the insertion rod 12 and ensuring that the protective cloth 10 is attached to the surface of the ventilation plate 5, thereby improving the waterproof effect.

[0037] Reference Figure 5 The installation mechanism includes a limit plate 17, which is slidably installed on the inner wall of the ventilation plate 5. A paddle 18 is fixedly connected to the left side of the limit plate 17 for facilitating the staff to move the limit plate 17, which is convenient and labor-saving. The limit plate 17 is elastically connected to the inner wall of the ventilation plate 5 through a spring 2 19. By setting the spring 2 19, the limit plate 17 has an elastic force away from the center position of the ventilation plate 5. A limit groove 20 matching the limit plate 17 is opened on the inner wall of the installation groove 6.

[0038] Working principle: When in use, the connecting block 11 is pulled downward to increase the length of the protective cloth 10 extending out of the rotating shaft 8, so that the rotating shaft 8 overcomes the elastic force of the torsion spring 9 and rotates, and then the insertion rod 12 is inserted into the slot 13 at the corresponding position. When the insertion rod 12 is inserted into the slot 13, the arc surface of the positioning rod 14 is squeezed by the edge of the slot 13, so that the positioning rod 14 overcomes the elastic force of the spring 15 and moves toward the center of the positioning rod 14. When the insertion rod 12 is fully inserted into the slot 13, the positioning rod 14 is stuck into the inside of the positioning groove 16 under the action of the spring 15, thereby improving the stability of the insertion rod 12 when it is inserted into the slot 13. At the same time, the elastic force of the torsion spring 9 keeps the protective cloth 10 in a taut state, so that the protective cloth 10 fits on the surface of the ventilation plate 5 to prevent rainwater from splashing into the interior of the electric energy meter box body 3 and causing damage to the electronic instrument, thereby improving the waterproof effect.

[0039] When it is necessary to remove the ventilation plate 5 to clean the dust screen, the paddle 18 is moved so that the two sets of limit plates 17 overcome the elastic force of the spring 2 19 and approach each other, and the limit plates 17 are detached from the inside of the limit groove 20, and then the ventilation plate 5 is pulled toward the direction close to the inside of the electric energy meter box body 3, so that the ventilation plate 5 can be easily removed from the inner wall of the mounting groove 6, thereby improving the convenience of disassembly and assembly of the ventilation plate 5.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
