[0028] Reference Figure 1-Figure 4According to an embodiment of the utility model, an electric energy meter box that is easy to dissipate heat includes a cabinet body 11 and a cabinet door 12. A cabinet cavity 13 that can be closed by the cabinet door 12 is provided in the cabinet body 11. The cabinet door 12 is hingedly installed and can be fixed at an angle by a lock. This is a prior art and will not be described in detail here. The left and right sides of the cabinet cavity 13 are respectively provided with a plurality of heat dissipation grooves 14 that penetrate outward and are evenly distributed up and down. The left and right sides of the cabinet body 11 are also provided with dust shields 15 that are adapted to the number of the heat dissipation grooves 14 and extend horizontally and then bend downward to cover the heat dissipation grooves 14.

[0029] In addition, a convex plate assembly is provided on the upper side of the cabinet body 11, and the convex plate assembly includes a plurality of convex plates 16 integrally formed on the upper side of the cabinet body 11 and distributed front and back. A groove extending into the convex plate 16 is provided in the upper side of the cabinet cavity 13 to keep the top wall thickness of the cabinet cavity 13 consistent. Through the setting of the convex plate 16, the upward hot air in the cabinet cavity 13 can have a larger contact area with the top surface of the cabinet body 11, which is beneficial to heat dissipation.

[0030] In order to protect the electrical components (not shown in the figure) installed in the cabinet cavity 13, a moisture-absorbing component is also included. The moisture-absorbing component includes a boss 21 integrally formed on the lower side of the cabinet body 11, and a connecting groove 22 connected to the cabinet cavity 13 is provided in the boss 21, and a mounting seat 23 is inserted upward into the connecting groove 22, and a moisture-absorbing material is placed in the upward-opening accommodating cavity in the mounting seat 23.

[0031] The hygroscopic material needs to be replaced from time to time. In order to facilitate the staff to observe the water content in the hygroscopic material to determine whether it needs to be replaced, the mounting seat 23 includes a base plate and a surrounding plate arranged on the base plate. A visual groove running through the base plate is provided, and a transparent plate is installed in the visual groove, that is, the staff can observe the hygroscopic material located in the surrounding plate through the transparent plate and determine whether it needs to be replaced. Specifically, in this embodiment, the hygroscopic material can be silica gel, which will change from blue to pink when saturated, so that the staff can observe and judge.

[0032] Since the metering box is generally mounted on a wall, in order to facilitate the staff to complete the replacement of the hygroscopic material without the aid of climbing tools, a control device for controlling the lifting of the mounting seat 23 is also included.

[0033] The control device includes a lifting plate 31 slidably connected to the vertical side of the cabinet 11, the mounting seat 23 is fixed to the side of the lifting plate 31, and a control rod 32 is rotatably connected inside the lifting plate 31. The control rod 32 extends to the end of the upper side of the lifting plate 31 and is equipped with a transversely extending cross plate 33. The cross plate 33 can be embedded between the front and rear convex plates 16, and the control rod 32 extends to the end of the lower side of the lifting plate 31 and is equipped with a handle 34.

[0034] When it is necessary to replace the hygroscopic material in the mounting seat 23, the staff first lifts the lifting plate 31 and the control rod 32 upwards to move the horizontal plate 33 to the upper side of the protruding plate 16, and then rotates the handle 34 so that the horizontal plate 33 is no longer directly above the cabinet 11. Then, the staff drives the lifting plate 31 and the mounting seat 23 to descend by the handle 34. After the mounting seat 23 is completely separated from the protruding platform 21, the staff can replace the hygroscopic material in the mounting seat 23. After the replacement is completed, the staff can push the rotary handle 34 and the lifting plate 31 upward to reset the mounting seat 23 to the communicating groove 22. When the lifting plate 31 is at the uppermost side, the transverse plate 33 is on the upper side of the protruding plate 16. Then the staff rotates the rotary handle 34 to set the transverse plate 33 horizontally to the left, and then sinks the lifting plate 31 to make the transverse plate 33 embedded between the protruding plates 16 to prevent the transverse plate 33 from rotating again. At this time, the hygroscopic material in the mounting seat 23 is replaced.

[0035] It should be additionally explained that, at this time, the mounting seat 23 can also move upwards a distance greater than the height of the protruding plate 16 .

[0036] In the second embodiment of the electric energy meter box that is easy to dissipate heat, in order to limit the lifting plate 31 downward and prevent the lifting plate 31 from sliding downward and away from the cabinet body 11 when the staff replaces the hygroscopic material in the mounting seat 23, a hook plate 41 is provided on the right side surface of the cabinet body 11 to act on the horizontal plate 33, and the control rod 32 is limited in the lifting plate 31 to control the angle, that is, when the user needs to move the lifting plate 31 downward, the control rod 32 rotates and makes the horizontal plate 33 face forward, and then the horizontal plate 33 is limited by the hook plate 41 when it moves downward to the limit distance.

[0037] In the third embodiment of the electric energy meter box that is easy to dissipate heat, in order to ensure that the connecting groove 22 can automatically maintain a closed state when the mounting seat 23 and the lifting plate 31 are removed, a side groove 35 that is upwardly connected to the cabinet cavity 13 is respectively provided in the left and right sides of the connecting groove 22, and a rotating shaft is rotatably connected in one of the side grooves 35, and a baffle 36 is fixed on the rotating shaft. When the mounting seat 23 is inserted into the connecting groove 22, the baffle 36 is abutted by the mounting seat 23 to maintain an upright state, and when the mounting seat 23 is removed, the side groove 35 will be horizontally arranged and close the connecting groove 22. The upper and lower distances of the baffle 36 when in the upright state are not less than the left and right widths of the connecting groove 22, so that the connecting groove 22 can abut the bottom surface of the other side groove 35 when it is horizontally arranged.

[0038] In addition, the baffle 36 is installed in the side groove 35 on the right side. The right side of the baffle 36 in the upright state is equipped with a spring that presses against the right side of the cabinet cavity 13 or the right side of the side groove 35. When the mounting seat 23 is removed, the baffle 36 will automatically fall down under the action of the spring without the need for manual adjustment by the staff.

[0039] It should be noted that the downward extension distance of the control rod 32 and the position of the handle 34 relative to the cabinet 11 can be adjusted according to the installation height of the cabinet 11, so that the staff can hold the handle 34 while standing on the ground.

[0040] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
