[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1-6 The present embodiment provides an energy-saving low-voltage electric energy metering box, comprising a box body 1, a box door 2 provided on the box body 1 by a hinge, a heat dissipation vent 3 provided on the box body 1, an installation mechanism 4 provided inside the box body 1, and a wiring tube 5 provided at the bottom of the box body 1.

[0027] In the present invention, the box body 1 serves as the core bearing structure, and the box door 2 connected by the hinge can be flexibly opened and closed. When the box door 2 is closed, it can effectively prevent the invasion of external dust, water vapor and foreign objects, and ensure the safety of internal equipment. The installation mechanism 4 in the box body 1 provides an adjustable installation carrier for electrical components (such as electricity meters, mutual inductors, etc.). The heat dissipation port 3 opened on the box body 1 uses the principle of natural air convection to discharge the heat generated by the electrical components during operation out of the box, so as to avoid the high temperature in the box affecting the measurement accuracy or aggravating the equipment loss. The wiring tube 5 at the bottom of the box body 1 is used for centrally passing the power supply incoming and outgoing cables, so that the line layout is regular and the risk of short circuit and leakage caused by cluttered lines is reduced.

[0028] In order to achieve flexible adjustment of the position of electrical components and facilitate their maintenance, the electrical components are installed in the box 1 through the installation mechanism 4. The installation mechanism 4 includes a mounting frame 41 for installing electrical components, and several pairs of guide tooth plates 42 arranged on the inner wall of the box 1. The mounting frame 41 can move along the length direction of the two guide tooth plates 42. Several mounting holes 44 are provided on the mounting frame 41. The end of the mounting frame 41 protrudes outward to form a guide rail 45, and the guide tooth plate 42 is provided with a guide groove 46 that cooperates with the guide rail 45.

[0029] Specifically, refer to Figure 1 、 Figure 3 and Figure 4 The guide tooth plate 42 is mounted on the inner wall of the box body 1 by screw fasteners, and the electrical components are mounted on the mounting bracket 41 by the cooperation of the fasteners and the mounting holes 44. The guide rail 45 protruding outward from the end of the mounting bracket 41 is precisely matched with the guide groove 46 opened on the guide tooth plate 42. The guide rail 45 is embedded in the guide groove 46 to form a sliding guide structure. The mounting bracket 41 can move smoothly along the length direction of the guide tooth plate 42 to achieve the front and rear adjustment of the installation position, thereby achieving the adjustment of the front and rear position of the electrical components in the box body 1;

[0030] It should be noted that several pairs of guide tooth plates 42 are arranged at equal intervals along the height direction of the inner wall of the box body 1, the number of mounting frames 41 is less than the number of pairs of guide tooth plates 42, and the guide tooth plates 42 are arranged at equal intervals along the height direction of the inner wall of the box body 1, providing multi-level installation options for the mounting frames 41. The staff can select the most suitable installation level from multiple pairs of guide tooth plates 42 according to the height size, quantity distribution or space planning of the electrical components, thereby improving the rationality of the installation layout. Combined with the design of the mounting frame 41 that can be adjusted back and forth, the component position can be optimized according to the internal space layout of the metering box, thereby improving space utilization.

[0031] In order to ensure that the electrical components on the mounting frame 41 are fixed in position after being moved back and forth and adjusted, and to ensure the stability of the electrical components when in use, limit assemblies 43 are provided at both ends of the mounting frame 41;

[0032] The limiting assembly 43 includes a fixed plate 431 movably mounted in the mounting groove at the end of the mounting frame 41. The fixed plate 431 is provided with a tooth block 432 that engages with the guide tooth plate 42. At least two springs 433 are provided between the fixed plate 431 and the inner wall of the mounting groove, and the fixed plate 431 is provided with a handle 434 that extends to the outside of the mounting frame 41.

[0033] Specifically, under the natural elastic force of the spring 433, the fixed plate 431 and the tooth block 432 movably mounted in the mounting groove at the end of the mounting frame 41 are pushed toward the guide tooth plate 42 and tightly meshed with the teeth of the guide tooth plate 42. At this time, the engagement between the teeth of the tooth block 432 and the guide tooth plate 42 limits the movement of the mounting frame 41 along the length direction of the guide tooth plate 42, so that the mounting frame 41 is stably fixed in the current position;

[0034] When the position of the mounting frame 41 needs to be adjusted, the operator pulls outward the handle 434 extending to the outside of the mounting frame 41, driving the fixing plate 431 and the tooth block 432 to move. At this time, the spring 433 is compressed and the tooth block 432 is disengaged from the guide tooth plate 42. The movement restriction of the mounting frame 41 is released, and the mounting frame can slide freely along the guide tooth plate 42 to adjust its position.

[0035] When the mounting bracket 41 is adjusted to the target position, the staff releases the handle 434, the spring 433 releases the elastic force to push the fixing plate 431 to reset, the tooth block 432 is precisely engaged with the guide tooth plate 42 again, the mounting bracket 41 is fixed again, and the positioning locking after the position adjustment is completed.

[0036] The inner wall of the box 1 is provided with a lamp for lighting during nighttime maintenance and inspection. In order to improve the energy-saving effect of the metering box, a photovoltaic mechanism 6 is provided on the top of the box 1 to power the lamp. The photovoltaic mechanism 6 includes a photovoltaic panel 61 provided above the box 1, and the photovoltaic panel 61 is detachably connected to the box 1 via a bracket assembly. The bracket assembly includes four support rods 62 hinged to the bottom of the photovoltaic panel 61 via a hinge seat, two of which are sleeved with connecting sleeves 63.

[0037] At least three positioning screw holes 64 are formed on the support rod 62 along its height direction, and the connecting sleeve 63 is provided with positioning bolts 65 that are threadedly engaged with the positioning screw holes 64 .

[0038] Among them, the photovoltaic panel 61 is installed above the box body 1 through a bracket assembly. The four support rods 62 of the bracket assembly are hinged to the bottom of the photovoltaic panel 61 through a hinge seat, so that the angle of the photovoltaic panel 61 can be rotated. When the angle of the photovoltaic panel 61 needs to be adjusted, the staff first loosens the positioning bolt 65 on the connecting sleeve 63, moves the support rod 62 up and down to the target height, and aligns the bolt hole of the connecting sleeve 63 with the positioning screw hole 64 at the corresponding position on the support rod 62, and then tightens the positioning bolt 65. The support rod 62 and the connecting sleeve 63 are fixed by threaded cooperation to complete the height locking. By differentially adjusting the height, the photovoltaic panel 61 can present the best tilt angle to adapt to the sunshine angle in different regions.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
