[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1 and 2As shown, a heat dissipation power metering box includes a box body 1 and a box cover 2. The box cover 2 is hinged to one side of the box body 1. A heat dissipation component 3 is fixedly installed on the top of the box body 1. An air intake component 4 is provided at the bottom of the box body 1. A cable assembly 5 is provided on one side of the box body 1 at equal intervals. A temperature detection switch 6 is fixedly installed inside the box body 1.

[0017] According to the above structure, when the heat dissipation component 3 is activated, it creates a negative pressure inside the housing 1. External air enters the housing 1 through the air intake component 4 at the bottom of the housing 1 and is then discharged through the heat dissipation component 3, thereby allowing air to circulate inside the housing 1 and facilitating cooling of the inside of the housing 1. When installing the electricity meter, the wiring is placed inside the wiring assembly 5 to prevent the wires inside the housing 1 from protruding and affecting air circulation, thus improving the heat dissipation effect.

[0018] like Figure 1 As shown, the surface of the box cover 2 is provided with uniformly distributed glass plates 21.

[0019] Based on the above structure, the glass plate 21 is positioned to facilitate observation of the power meter inside the housing 1.

[0020] like Figure 2 and 3 As shown, the heat dissipation component 3 includes a housing 31 fixedly connected to the top of the box 1. The surface of the housing 31 is provided with equidistantly distributed ventilation slots 32. Equidistantly distributed fans 33 are fixedly installed inside the housing 31. Several fans 33 are respectively arranged corresponding to several ventilation slots 32. The bottom of the box 1 is provided with equidistantly distributed air inlets 11. The air intake component 4 includes a square tube 41 fixedly connected to the bottom of the box 1. Equidistantly distributed triangular guide blocks 42 are fixedly connected to the top of the inner wall of the square tube 41. Equidistantly distributed baffles 43 are fixedly connected to the bottom of the inner side of the square tube 41. The triangular guide blocks 42 and the baffles 43 are staggered. An air passage 44 is provided between the baffles 43 and the adjacent triangular guide blocks 42. The top of the air passage 44 is arranged corresponding to the air inlet 11. The fans 33 are electrically connected to an external power supply through a temperature detection switch 6.

[0021] According to the above structure, when the temperature inside the housing 1 reaches the set temperature of the temperature detection switch 6, the temperature detection switch 6 closes, the fan 33 starts, and the air inside the housing 1 is discharged to the outside through the ventilation slot 32. After the negative pressure is generated inside the housing 1, the outside air enters the inside of the housing 1 through the air passage 44, thereby forming an air circulation. The air inlet 11 corresponds to the gap between each row of meters, which facilitates the air flow. In addition, the fan 33 and the air inlet 11 are vertically aligned to improve the smoothness of air flow and facilitate heat dissipation. The air passage 44 is set at an angle to effectively prevent rainwater from splashing into the inside of the housing 1 through the air passage 44.

[0022] like Figure 4 As shown, the cable assembly 5 includes a U-shaped groove 51 fixedly connected to one side of the housing 1. The U-shaped groove 51 is fixedly connected with cable clamping components 52 that are evenly distributed. The cable clamping components 52 include a C-shaped plate 521 fixedly connected to the inside of the U-shaped groove 51. Both ends of the C-shaped plate 521 are fixedly connected with guide plates 522. One end of the U-shaped groove 51 is provided with a cable routing hole 53.

[0023] According to the above structure, during the wiring process, the wire is placed inside the U-shaped groove 51. During the wiring process, the wire squeezes the guide plate 522 to open the opening of the C-shaped plate 521, making it easier for the wire to enter the interior of the C-shaped plate 521. The C-shaped plate 521 has a limiting effect on the wire, preventing the wire from bulging outward and obstructing the airflow.

[0024] The working principle of this utility model is as follows: When the temperature inside the box 1 reaches the set temperature of the temperature detection switch 6, the temperature detection switch 6 closes, the fan 33 starts, and the air inside the box 1 is discharged to the outside through the ventilation groove 32. After the negative pressure is generated inside the box 1, the external air enters the inside of the box 1 through the air passage 44, thereby forming an air circulation. The air inlet 11 corresponds to the gap between each row of meters, which facilitates the air flow. In addition, the fan 33 and the air inlet 11 are vertically aligned to improve the smoothness of air flow and facilitate heat dissipation. When laying the wires, the wires are placed inside the U-shaped groove 51. When laying the wires, the wires squeeze the guide plate 522 to open the opening of the C-shaped plate 521, which facilitates the wires to enter the inside of the C-shaped plate 521. The C-shaped plate 521 has a limiting effect on the wires to prevent the wires from bulging outward and obstructing the air flow.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
