[0004] Outdoor electricity metering boxes are usually equipped with heat dissipation and ventilation components to ensure the normal operation of the metering components. However, the placement of these heat dissipation and ventilation points often makes them susceptible to intrusion by dust, insects, animals, rainwater, etc., leading to inaccurate or damaged metering components and requiring frequent maintenance. While completely sealing the electricity metering box can completely block the external environment, it cannot guarantee the internal heat dissipation requirements. Furthermore, in some extreme high-temperature environments, the internal heat dissipation equipment may be unable to meet the heat dissipation requirements, resulting in overheating problems. Summary of the Invention

[0016] Furthermore, the top of the cooling box is fixedly connected to an inlet pipe, and the bottom is fixedly connected to an outlet pipe; valves are installed on both the inlet and outlet pipes; and mounting lugs are fixedly provided on one side of the cooling box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This invention, through the cooperation of the cooling box, cooling pipe and connecting pipe mechanism, can achieve both complete sealing protection and ensure internal heat dissipation. Specifically, through the completely sealed structure design of the inner and outer boxes, dust, insects, animals, rainwater and other contaminants cannot enter the inner box and affect the power metering equipment. At the same time, the regulating pipe mechanism connects both cooling pipes to the inside of the inner box. At this time, due to the opposite direction of the two one-way valves, when the forward and reverse fans are performing the exhaust operation, one of the one-way valves opens, and the hot air generated by the operation of the equipment inside the inner box is drawn out and enters the interior of one of the cooling pipes to be cooled by the external coolant. After cooling, it enters the bottom of the outer box and returns to the interior of the inner box through the vent, thus forming a circulating heat dissipation. At this time, due to the airflow direction, the other one-way valve is always closed, so the other one-way valve... One cooling tank is in standby mode. When the coolant temperature in the operating cooling tank rises and it can no longer effectively dissipate heat, the reversible fan reverses the exhaust operation. At this time, due to the change in airflow direction, another one-way valve opens, while the previously opened one-way valve closes. Thus, the reversible fan exhausts the cold air from the cooling pipes of the other cooling tank into the inner tank, and forces the previously hot air from inside the inner tank out through the vent at the bottom, allowing it to enter the cooling pipes of the other cooling tank to exchange heat with the coolant. The cooling tank that cannot dissipate heat at this time is in standby mode due to the closed one-way valve. This allows the cooling tank to transfer the heat of the coolant to the outside to restore its cooling capacity, waiting for the next cycle. In this way, the inner tank always has a certain heat dissipation capacity, avoiding the problem of poor heat dissipation that can occur in a closed environment, even though it provides complete protection.

[0019] (2) This invention, through the cooperation of the connecting pipe mechanism and the switching mechanism, can achieve closed-loop heat dissipation under normal conditions, and at the same time, can ensure the heat dissipation effect in extreme high-temperature weather. It also greatly avoids contact between the internal equipment and the outside world, has controllability, greatly improves the protection effect, and does not require frequent maintenance and cleaning. Specifically, when the second vent is connected to the first filter screen and the second vent is not connected to the outside during normal heat dissipation, the venting screen is not connected to the outside. In this state, under the switching operation of the forward and reverse fan, the air always circulates inside the closed space and can ensure the heat dissipation effect. When extreme high-temperature weather occurs outside, the coolant needs to be cooled. To withstand the reduced heat dissipation caused by high external temperatures, the forward and reverse motors are activated. The rotation of these motors, via gear 74, controls the synchronous rotation of the gear ring and the connecting pipe mechanism. Since the upper end of the connecting pipe body is threaded to the bottom of the switching cylinder, and the limiting block of the switching cylinder slides vertically within the slide rail, the rotation of the connecting pipe mechanism causes the switching cylinder to move vertically. This allows the second vent to simultaneously connect to both the first filter and the outside environment, while the vent cylinder is also synchronously connected to the external portion. At this time, when the forward and reverse fans draw air, the primary airflow direction remains internal circulation. However, some external air will enter through the second vent, participate in heat dissipation, and then be exhausted through the vent mesh, thus solving the problem of insufficient coolant cooling. When the fan exhausts air in both directions, some external air will enter through the vent mesh, participate in heat dissipation, and then be exhausted through the second vent. This switching ensures effective heat dissipation, and the changing airflow direction blows away dust adhering to the vent mesh and second vent, preventing fine dust from entering the interior and greatly minimizing contact between internal equipment and the outside environment. The switching cylinder is moved to the top when the coolant has lost its cooling capacity. The second vent is connected to the outside but not to the first filter screen, and the venting screen is fully connected to the outside. At this time, the cooling pipe is completely closed. The operation of the forward and reverse fans will only exchange the air inside the inner box with the air outside the outer box to achieve external circulation heat dissipation. At this time, the cooling box is in standby mode and slowly restores its heat dissipation capacity. After it is restored, the reverse rotation of the forward and reverse motor will perform controllable internal and external circulation. This ensures the heat dissipation effect even in extreme high temperature weather and is controllable. The ratio of internal and external air circulation can be flexibly adjusted, which greatly avoids the internal equipment of the inner box from contacting the outside, greatly improves the protection effect, and eliminates the need for frequent maintenance and cleaning.

It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0033] Example

[0034] like Figures 1-9 As shown, an energy metering box that combines protection and heat dissipation includes an outer casing 100, with cooling boxes 200 fixedly connected to both sides of the outer casing 100 and filled with coolant. An inner casing 400 is fixedly connected to the middle of the outer casing 100, and an energy metering device is fixedly installed inside the inner casing 400. A cooling pipe 500 is provided inside the cooling box 200, and the cooling pipe 500 is in a continuously bent state. One end of the cooling pipe 500 passes through the cooling box 200 and the lower side wall of the outer casing 100 and extends into the interior of the outer casing 100, while the other end of the cooling pipe 500 passes through the top of the cooling box 200 and is fixedly connected to an adjusting pipe mechanism 800. A connecting pipe mechanism 700 is installed on the top of the outer casing 100 and the inner casing 400, which connects the interior of the inner casing 400 to the adjusting pipe mechanism 800. Multiple ventilation holes 420 are provided at the bottom of the inner casing 400.

[0035] The present invention, through the cooperation of the cooling box 200, the cooling pipe 500 and the connecting pipe mechanism 700, can achieve both complete sealing and protection and ensure internal heat dissipation; a detailed description will follow.

[0036] Furthermore, the connecting pipe mechanism 700 includes a connecting pipe body, and a forward and reverse fan 750 is fixedly installed inside the connecting pipe body; a one-way valve 510 is installed at the connection between the cooling pipe 500 and the regulating pipe mechanism 800, and the two one-way valves 510 are in opposite directions.

[0037] This invention utilizes a completely enclosed structure between the inner casing 400 and the outer casing 100, preventing dust, insects, animals, rainwater, etc., from entering the inner casing 400 and affecting the electricity metering equipment. Simultaneously, the regulating pipe mechanism 700 connects both cooling pipes 500 to the interior of the inner casing 400. Due to the opposing directions of the two one-way valves 510, when the reversible fan 750 is operating, one of the one-way valves 510 opens, drawing out the hot air generated by the equipment inside the inner casing 400 and drawing it into one of the cooling pipes 500 where it is cooled by external coolant. After cooling, the air enters the bottom of the outer casing 100 and returns to the inner casing 400 through the vent 420, thus forming a circulating cooling system. Meanwhile, due to the airflow direction, the other one-way valve 510 remains closed, so the other cooling box 200 is in standby mode. When the cooling box 200 is in operation... When the coolant temperature rises and fails to dissipate heat effectively, the reversible fan 750 reverses its exhaust operation. Due to the change in airflow direction, another one-way valve 510 opens, while the previously opened one-way valve 510 closes. Thus, the reversible fan 750 exhausts the cold air from the cooling pipes 500 inside the other cooling tank 200 into the inner tank 400, and forces the previously hot air inside the inner tank 400 out through the bottom vent 420, allowing it to enter the cooling pipes 500 of the other cooling tank 200 to exchange heat with the coolant. The cooling tank 200, which is currently unable to dissipate heat, is in standby mode due to the closed one-way valve 510. This allows the cooling tank 200 to transfer heat from the coolant to the outside to restore its cooling capacity, awaiting the next cycle. This ensures that the inner tank 400 always has a certain amount of heat dissipation capacity, avoiding the problem of poor heat dissipation that can occur in a closed environment, despite its complete protective function.

[0038] It is worth noting that the power equipment such as the forward and reverse fan 750 of this invention are all powered by an external power source, which is a conventional setting and will not be described in detail here.

[0039] Furthermore, the connecting pipe mechanism 800 includes an annular groove 810, the two outer sides of which are fixedly connected to a one-way valve 510 via an intermediate pipe 840; vertical fixing blocks 830 are symmetrically fixedly connected inside the annular groove 810, and a slide rail 831 is provided on one side of the fixing block 830; the inner ring of the annular groove 810 is provided as a first filter screen 820; an annular cover 811 is fixedly installed on the top of the annular groove 810; and a switching mechanism 900 is slidably connected to the slide rail 831.

[0040] This invention, through the cooperation of the connecting pipe mechanism 800 and the switching mechanism 900, can achieve closed-loop heat dissipation under normal conditions, and at the same time, can ensure the heat dissipation effect in extreme high temperature weather. It also greatly avoids the internal equipment of the inner casing 400 from contacting the outside world, which is controllable, greatly improves the protection effect, and eliminates the need for frequent maintenance and cleaning; a detailed description will follow.

[0041] Furthermore, the switching mechanism 900 includes a switching cylinder 910, the top of which is closed and the bottom of which has an internal thread; the side wall of the switching cylinder 910 is symmetrically fixed with a limiting block 911, the limiting block 911 being slidably connected to the slide rail 831; a plurality of second vents 920 are provided on the upper side of the side wall of the switching cylinder 910; the upper end of the connecting pipe body of the connecting pipe mechanism 700 has an external thread end 701, which is threadedly connected to the bottom of the switching cylinder 910.

[0042] Furthermore, the connecting pipe mechanism 700 has a toothed ring 710 fixedly connected to the middle of the connecting pipe body, and the connecting pipe body is rotatably connected to the top of the outer box 100 and the inner box 400 respectively through bearings 720; a forward and reverse motor 730 is fixedly installed on the top of the inner box 400, and the gear 740 at the output end of the forward and reverse motor 730 meshes with the toothed ring 710; the external thread end 701 is located outside the outer box 100.

[0043] Furthermore, the bottom sides of the switching cylinder 910 are symmetrically fixedly connected with support rods 930, one end of the support rod 930 is fixedly connected with a ventilation mesh cylinder 940, and the top of the ventilation mesh cylinder 940 is closed; the top of the outer box 100 is provided with a sliding hole 120, and the ventilation mesh cylinder 940 is slidably connected to the sliding hole 120.

[0044] When the present invention is used for conventional heat dissipation, such as Figure 2 As shown, when the second vent 920 is connected to the first filter screen 820 and the second vent 920 is not connected to the outside, the vent screen cylinder 940 is not connected to the outside. In this state, under the switching operation of the forward and reverse fan 750, the air always circulates inside the closed space, and the heat dissipation effect is guaranteed. When extreme high temperatures occur outside, the coolant needs to withstand the high temperature radiation from the outside, which reduces the heat dissipation capacity. At this time, if... Figure 9As shown in state 2, by starting the forward and reverse motor 730, the rotation of the forward and reverse motor 730 controls the gear ring 710 and the connecting pipe mechanism 700 to rotate synchronously through the gear 74. At this time, since the upper end of the connecting pipe body of the connecting pipe mechanism 700 is threadedly connected to the bottom of the switching cylinder 910, and the limiting block 911 of the switching cylinder 910 slides vertically within the slide rail 831, the rotation of the connecting pipe mechanism 700 can drive the switching cylinder 910 to move vertically. Thus, the second vent 920 is simultaneously connected to the first filter screen 820 and the outside, and the vent screen cylinder 940 is also synchronously driven to connect to the outside. At this time, when the forward and reverse fan 750 draws air, the main... The system maintains the same airflow direction as internal circulation, but some external air will enter through the second vent 920, participate in heat dissipation, and then be exhausted through the vent 940, thus addressing insufficient coolant cooling. Conversely, when exhausting air through the reversible fan 750, some external air will enter through the vent 940, participate in heat dissipation, and then be exhausted through the second vent 920. This switching ensures effective heat dissipation, and the changing airflow direction blows away dust adhering to the vent 940 and second vent 920, preventing fine dust from entering the interior and greatly minimizing contact between the internal components of the inner casing 400 and the outside environment. This continues until the coolant loses its cooling capacity, such as... Figure 9 As shown in state 3, the switching cylinder 910 is moved to the top. At this time, the second vent 920 is connected to the outside but not to the first filter screen 820, and the vent screen cylinder 940 is fully connected to the outside. At this time, the cooling pipe 500 is completely closed. The operation of the forward and reverse fan 750 will only exchange the air inside the inner box 400 with the air outside the outer box 100 to achieve external circulation heat dissipation. At this time, the cooling box 200 is in standby state and slowly restores its heat dissipation capacity. After it is restored, the forward and reverse motor 730 reverses to perform controllable internal and external circulation. This ensures the heat dissipation effect even in extreme high temperature weather and is controllable. The ratio of internal and external air circulation can be flexibly adjusted, which greatly avoids the internal equipment of the inner box 400 from contacting the outside, greatly improves the protection effect, and eliminates the need for frequent maintenance and cleaning.

[0045] It is worth noting that the present invention can install temperature measuring devices inside the inner box 400 and the cooling box 200, and use a PLC system to control the temperature measuring devices, the forward and reverse fan 750 and the forward and reverse motor 730 in a coordinated manner, thereby making corresponding adjustments. This is a mature existing technology and will not be described in detail or further limited here.

[0046] Furthermore, when the second vent 920 is connected to the first filter screen 820 but not connected to the outside, the ventilated mesh cylinder 940 is not connected to the outside; when the second vent 920 is connected to both the first filter screen 820 and the outside, the ventilated mesh cylinder 940 is partially connected to the outside; when the second vent 920 is connected to the outside but not to the first filter screen 820, the ventilated mesh cylinder 940 is fully connected to the outside.

[0047] Furthermore, the top of the outer casing 100 and the cooling box 200 are provided with a shielding mechanism 300. The shielding mechanism 300 includes two support plates 310, which are fixed to the outer top of the corresponding cooling box 200. A baffle 320 is fixedly connected to both support plates 310, and a mesh plate 330 is fixedly connected to the front of both support plates 310. The baffle 320 and the mesh plate 330 can provide initial protection against rain and dust.

[0048] Furthermore, an outer door 110 is hinged to the front of the outer casing 100, and an outer transparent panel 111 is fixedly mounted on the outer door 110; an inner door 410 is installed at the front of the inner casing 400, and an inner transparent panel 411 is fixedly mounted on the inner door 410. The display of the internal measuring equipment can be directly observed through the outer transparent panel 111 and the inner transparent panel 411. At the same time, the outer door 110 and the inner door 410 facilitate subsequent maintenance, and a sealing strip can be installed at the door seam to improve the sealing performance.

[0049] Furthermore, the top of the cooling tank 200 is fixedly connected to an inlet pipe 220, and the bottom is fixedly connected to an outlet pipe 210; valves are installed on both the inlet pipe 220 and the outlet pipe 210; a mounting lug is fixedly provided on one side of the cooling tank 200. New coolant can be easily added and replaced through the inlet pipe 220 and the outlet pipe 210; the mounting lug allows the metering tank to be installed on the wall.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
