Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without doing creative work premise, belong to the scope of the utility model protection.

[0050] Please refer to Figures 1-13The utility model discloses an outdoor circular electric energy meter shell with good heat dissipation effect, and the outdoor circular electric energy meter shell comprises a bottom shell, an inner cover, an outer cover and a heat dissipation assembly. Figure 1 、 Figure 2 、 Figure 9 As shown in the figure, the utility model discloses an outdoor circular electric energy meter shell with good heat dissipation effect, and the outdoor circular electric energy meter shell comprises a bottom shell, an inner cover, an outer cover and a heat dissipation assembly.

[0051] The bottom shell is installed perpendicularly to the wall surface, and the connecting pieces on the bottom of the bottom shell are used for connecting the circuit. The circular inner cover and the outer cover are installed in a manner that the axis thereof is perpendicular to the wall surface, so that when rainwater is encountered, the rainwater can flow down along the outer cover, thereby realizing the rainproof effect. The installation mode and the waterproof mode of the bottom shell of the prior art outdoor circular electric energy meter are well known to those skilled in the art and will not be described here again. The inner cover is rotatably fixed to the bottom shell through the first clamping assembly, thereby forming a detachable connection. The outer cover is rotatably fixed to the bottom shell through the second clamping assembly, thereby forming a detachable connection.

[0052] Preferably, the outer cover is made of transparent plastic material, and a reading port is formed on the outer side wall of the outer cover. The 485 meter probe can be installed on the reading port through the adhesive or magnetic suction mode.

[0053] The specific shape of the bottom shell is shown in the figure, Figures 9-13 , Figure 11 is an installation state diagram of the bottom shell. One end of the connecting piece is electrically connected to the circuit board of the electric energy meter, and the other end of the connecting piece penetrates through the bottom shell. The bottom shell can be connected to the external electric energy meter connection structure through the connecting piece.

[0054] Preferably, a ring groove is formed on the outer side wall of the bottom shell, and a ring-shaped part is formed on the side wall of the outer cover. The ring-shaped part can be inserted into the ring groove. The positions of the ring groove and the ring-shaped part are shown in the figures, Figure 5 、 Figure 9 、 Figure 13 By arranging the ring groove and the ring-shaped part, a waterproof barrier is formed between the outer cover and the bottom shell, so that the sealing performance of the outer cover and the bottom shell is better.

[0055] By setting the heat dissipation assembly 5 between the inner cover 3 and the outer cover 4, a convection channel is formed between the inner cover 3 and the outer cover 4, and the heat generated by the internal electronic components is effectively dissipated out of the shell. At the same time, the heat dissipation channel adopts a circuitous isolation design, which avoids the direct intrusion of external rainwater, effectively prevents the intrusion of rainwater, and enhances the heat dissipation effect.

[0056] By setting the first clamping assembly and the second clamping assembly, the inner cover 3 and the outer cover 4 are tightly fixed with the bottom shell 1, forming multiple sealed interfaces. This structure not only effectively prevents rainwater from seeping in, but also improves the overall structural strength of the watch case and the long-term reliability in complex outdoor environments.

[0057] As shown in Figure 6 , Figure 7 , Figure 8 , the heat dissipation assembly 5 includes a sealing half circle 51, a sealing strip 52, an exhaust port one 53, an exhaust port two 54, an air inlet hole 55, and an air inlet 56. The sealing half circle 51 is arranged on the outer side wall of the inner cover 3, and the sealing strip 52 is arranged in pairs on the inner circumferential wall of the outer cover 4. The exhaust port one 53 is arranged at the top of the side wall of the inner cover 3, the exhaust port two 54 is arranged at the bottom of the side wall of the outer cover 4, the air inlet hole 55 is arranged on the outer side wall of the inner cover 3, and the air inlet 56 is arranged at the bottom of the side wall of the outer cover 4. Preferably, as shown in Figure 8 , the heat dissipation assembly 5 further includes an exhaust fan 57, which is installed at the exhaust port one 53.

[0058] In this embodiment, the positions of the exhaust port one 53, the exhaust port two 54, the air inlet hole 55, and the air inlet 56 are as shown in Figure 7 . The inner cover 3 and the outer cover 4 form a convection heat dissipation channel. Since the application is vertically installed, the exhaust port one 53 is vertically upward, and the exhaust port two 54 and the air inlet 56 are vertically downward. Heat is generated inside the inner cover 3, forming hot air, which naturally rises and is discharged from the exhaust port one 53. The hot air moves downward along the inner wall of the outer cover 4 and is discharged from the exhaust port two 54 at the bottom of the outer cover 4. When the hot air is discharged, a certain degree of negative pressure is formed inside the inner cover 3, which promotes the entry of external cold air into the inner cover 3 through the air inlet 56 at the bottom of the outer cover 4 and the air inlet hole 55 on the outer side wall of the inner cover 3, forming a circulation cycle.

[0059] The positions of the sealing half circle 51 and the sealing strip 52 are as shown in Figure 6 . The sealing half circle 51 and the sealing strip 52 separate the inner cover 3 and the outer cover 4 into two circuitous convection channels. Since the inner cover 3 and the outer cover 4 are rotationally fixed with the bottom shell 1, the sealing half circle 51 and the sealing strip 52 should be made of flexible rubber material with certain deformation ability.

[0060] The position of the exhaust fan 57 is as shown in Figure 8As shown, the exhaust fan 57 can push hot air out of the exhaust port one 53 and the exhaust port two 54, accelerate air circulation, and improve heat exchange efficiency. The exhaust fan 57 is electrically connected to the electric energy meter mainboard through an electric wire. The electric energy meter mainboard is provided with a control module for controlling the exhaust fan 57. The control module includes a step-down transformer, a rectifier, a filter capacitor, and a voltage stabilizing chip. The transformer is used to reduce the voltage to a safe voltage. The rectifier is used to convert alternating current into direct current. The filter capacitor is used to smooth the waveform. The voltage stabilizing chip is used to output a stable voltage.

[0061] By setting the sealing half-ring 51, the sealing strip 52, the exhaust port one 53, the exhaust port two 54, the air inlet hole 55, and the air inlet port 56, and by the cooperation of the sealing half-ring 51 and the sealing strip 52, a heat dissipation channel that can circulate is formed between the inner cover 3, the outer cover 4, and the bottom shell 1. By using the principle of hot air rising, efficient heat exchange and air circulation are realized. At the same time, combined with the active heat dissipation capacity of the exhaust fan 57, it is ensured that the appropriate working temperature in the shell can be maintained under high load or high temperature environment.

[0062] As shown in Figure 3 , Figure 9 , Figure 11 , Figure 13 , the first clamping assembly includes a supporting plate 12, a limiting strip 13, and a clamping block 31. The supporting plate 12 is arranged on the inner side wall of the bottom shell 1 and is used to install the inner cover 3. The limiting strip 13 is arranged on the inner side wall of the bottom shell 1. The clamping block 31 is arranged on the outer side wall of the inner cover 3 and can form clamping connection with the limiting strip 13.

[0063] In this embodiment, the shape and arrangement position of the supporting plate 12 and the limiting strip 13 are as shown in Figure 9 , and the shape and arrangement position of the clamping block 31 are as shown in Figure 3 . The inner cover 3 is pressed on the end of the supporting plate 12. After the inner cover 3 is rotated, the clamping block 31 enters the space between the supporting plate 12 and the limiting strip 13 to form clamping connection.

[0064] As shown in Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , the second clamping assembly includes a fixed block 14 and a clamping block 42. The fixed block 14 is arranged on the outer side wall of the bottom shell 1. A fixed groove 15 is formed on the side wall of the fixed block 14. The clamping block 42 is arranged on the inner side wall of the outer cover 4 and can form clamping connection with the fixed groove 15.

[0065] In this embodiment, the shape and arrangement position of the fixed block 14 and the clamping block 42 are as shown in Figure 9 , Figure 10 , Figure 11As shown, the setting position of the clamping block 42 is as shown. Figure 7 The edge of the outer cover 4 is sleeved outside the fixing block 14, after the outer cover 4 is rotated, the clamping block 42 enters into the fixing groove 15 to form the clamping connection.
