[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0032] Please see Figure 1-6 As shown, a photovoltaic power station meter mounting base includes:

[0033] Mounting base assembly 1, the mounting base assembly 1 includes mounting base 101 and inner housing 103, the mounting base 101 has an inner cavity, the inner housing 103 is fixedly disposed in the inner cavity of the mounting base 101, and an electricity meter 2 is fixedly connected to the inner wall of the inner housing 103;

[0034] The exhaust assembly 3 is fixedly disposed above the mounting base assembly 1, and the exhaust assembly 3 is used to exhaust the hot air inside the mounting base assembly 1.

[0035] The auxiliary heat dissipation component 4 is fixedly installed below the mounting base assembly 1. When used outdoors, the auxiliary heat dissipation component 4 automatically allows external air to enter the interior of the mounting base assembly 1.

[0036] Through the above technical solution, by using the exhaust component 3 and the auxiliary heat dissipation component 4 together, the automatic cooling function can be achieved in a wide outdoor environment, avoiding damage caused by prolonged high temperature, while not requiring an additional power source and being easy to use.

[0037] The mounting base 101 is hinged to a fixed cover 102 at its opening to form a flip-open structure. Preferably, a latch is installed between the mounting base 101 and the fixed cover 102.

[0038] The exhaust assembly 3 includes an exhaust shell 301, an arc-shaped baffle 303, and a rain shield 304. The bottom end of the exhaust shell 301 extends to the upper side of the inner cavity of the inner shell 103 and is fixedly connected to the inner shell 103. The upper end of the exhaust shell 301 extends to the outside of the inner cavity wall of the mounting base 101 and is fixedly connected to the mounting base 101. The bottom of the exhaust shell 301 is provided with an opening, and a plurality of exhaust holes 302 are provided on the upper wall of the inner cavity of the exhaust shell 301. Through this technical solution, when the internal temperature of the mounting base assembly 1 is high, the high-temperature gas flows upward, allowing the gas to be discharged through the exhaust holes 302.

[0039] An arc-shaped baffle 303 is fixedly installed in the inner cavity of the exhaust shell 301. Several arc-shaped baffles 303 are provided and are arranged in a cross pattern in the inner cavity of the exhaust shell 301. Through this technical solution, the cross design of the arc-shaped baffles 303 can block impurities without affecting the exhaust of hot air. When external impurity particles enter the inner cavity of the exhaust shell 301, the particles come into contact with the arc-shaped baffles 303. Due to the obstruction of the arc-shaped baffles 303, the particles will fall into the arc-shaped recess of the arc-shaped baffles 303, thereby reducing the pollution caused by impurity particles entering the interior of the inner shell 103.

[0040] A rain shield 304 is provided at the top of the exhaust shell 301. One end of a support rod 305 is fixedly connected to the bottom surface of the rain shield 304, and the other end of the support rod 305 is fixedly connected to the upper surface of the mounting base 101. Through this technical solution, the rain shield 304 can prevent rainwater from flowing back into the interior of the exhaust shell 301 during rainy weather.

[0041] Specifically, the exhaust holes 302 of the exhaust shell 301 are circular holes with a diameter of 3-5 mm and a spacing of 10-15 mm, arranged in a matrix, with the total open area accounting for 20%-30% of the upper wall area of ​​the exhaust shell; the arc-shaped baffle 303 is a stainless steel arc-shaped sheet, with 2-5 layers, each layer containing 4-6 pieces, an arc radius of 5-8 cm, arranged in a cross pattern, and an arc-shaped recess depth of 2-3 cm, ensuring that dust or small particulate impurities fall into the recess and do not enter the inner shell 103; the rain shield 304 is a 300 mm × 200 mm rectangle, and the support rod 305 is 100-150 mm high. Under windless or weak wind conditions, this embodiment relies on natural convection for heat dissipation: when the internal temperature of the mounting base rises, the density of hot air decreases, and it rises naturally through the exhaust holes 302 to be discharged, achieving passive heat dissipation.

[0042] The auxiliary heat dissipation assembly 4 includes a rectangular air intake pipe 401, an air intake shell 402, a fan 409, and a wind-driven unit. The rectangular air intake pipe 401 is fixedly installed on the bottom wall of the mounting base 101, and its upper end extends to the bottom side of the inner cavity of the inner shell 103. The upper end of the rectangular air intake pipe 401 is fixedly connected to the air intake shell 402. Several air intake holes 403 are opened on the upper wall of the inner cavity of the air intake shell 402, and a dust filter 404 is fixedly connected to the inner cavity of the air intake shell 402.

[0043] A fixed bracket 407 is fixedly connected to the inner cavity of the rectangular air intake pipe 401. A rotating central shaft 408 is rotatably connected to the fixed bracket 407. A fan 409 is fixedly connected to the arc-shaped wall of the rotating central shaft 408. A wind-driven unit is provided on the side wall of the rectangular air intake pipe 401. The wind-driven unit is used to drive the rotating central shaft 408 to rotate.

[0044] The wind-driven unit includes a rotating rod 405, a turbine 406, a driven bevel gear 410, and a driving bevel gear 411. The driven bevel gear 410 is fixedly connected to the arc-shaped wall of the rotating central shaft 408. The rotating rod 405 is rotatably connected to the side wall of the rectangular air intake pipe 401. One end of the rotating rod 405 is fixedly connected to the turbine 406, and the other end of the rotating rod 405 is fixedly connected to the driving bevel gear 411. The driving bevel gear 411 and the driven bevel gear 410 mesh with each other.

[0045] Furthermore, the number of teeth of the active bevel gear 411 is greater than the number of teeth of the driven bevel gear 410. With this technical solution, when the device is used in an open outdoor environment, when there is wind, the wind can automatically drive the turbine 406 to rotate, which in turn drives the rotating rod 405 to rotate. The rotation of the rotating rod 405 can drive the active bevel gear 411 to rotate, which in turn drives the driven bevel gear 410 to rotate, thereby driving the rotating central shaft 408 to rotate, which in turn drives the fan 409 to rotate. The rotation of the fan 409 can cause the external air to blow from bottom to top, allowing the external cold air to enter the inner cavity of the inner shell 103 from bottom to top, providing wind-cooled auxiliary heat dissipation for the energy meter 2.

[0046] Preferably, the driving bevel gear 411 of the wind-driven unit has 30 teeth, and the driven bevel gear 410 has 15 teeth, i.e., a gear ratio of 2:1. The turbine 406 is a wind turbine blade with a diameter of 80mm, and the material is lightweight aluminum alloy. Under wind conditions, the wind-driven unit starts: the turbine 406 drives the rotating rod 405, which drives the fan 409 to rotate through gear meshing. External air enters through the dust filter 404 to achieve air cooling.

[0047] In one specific embodiment, the mounting base 101 is made of weather-resistant engineering plastic material, preferably polycarbonate or glass fiber reinforced nylon, with a thickness of 2-4 mm, to provide resistance to ultraviolet aging.

[0048] The inner cavity of the mounting base 101 has dimensions of 300mm long × 200mm wide × 150mm high. The inner shell 103 is fixed in the inner cavity. The inner shell 103 is made of aluminum alloy 6061 with a thermal conductivity ≥150W / (m·K) and a thickness of 1.5-2.5mm.

[0049] The inner wall of the inner housing 103 is fixedly connected to the energy meter 2 by bolts. The energy meter 2 is a standard three-phase smart energy meter with dimensions of 180mm×110mm×60mm. The hinge point between the fixed cover 102 and the mounting base 101 is located at the front edge of the mounting base, and the latch is a stainless steel latch lock.

[0050] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
