[0036] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0037] As Figures 1 to 9 shown, a preferred embodiment of the present invention provides a reliability detection device for an electric energy meter, which includes a bracket and a heat dissipation module;

[0038] The bracket includes a support frame 1 and a mounting rack 2. A plurality of mounting racks 2 are arranged in parallel within the support frame 1. The mounting racks 2 are used for mounting and fixing a plurality of low-voltage electric energy metering boxes 3 to be detected;

[0039] The heat dissipation module includes a circulating heat dissipation structure and a rain shielding structure; the circulating heat dissipation structure includes a connected heat dissipation water tank 4 and heat dissipation water pipes 5. The heat dissipation water tank 4 is fixedly arranged on the support frame 1, and the heat dissipation water pipes 5 are arranged inside the low-voltage power metering box 3. A circulating pipeline 6 is also provided between the heat dissipation water tank 4 and the heat dissipation water pipes 5, and the circulating pipeline 6 is used to drive the coolant to circulate between the heat dissipation water tank 4 and the heat dissipation water pipes 5;

[0040] The rain shielding structure includes a triggering member 7 and a rain shielding member 8. There are multiple rain shielding members 8 corresponding to the low-voltage power metering box 3. The rain shielding member 8 includes a baffle 81, and the baffle 81 is slidably connected to the low-voltage power metering box 3 to shield the heat dissipation holes 31 opened on the low-voltage power metering box 3; the triggering member 7 includes a floating ball 71 and a connecting rod assembly 72. The floating ball 71 is arranged in the heat dissipation water tank 4, and the connecting rod assembly 72 is respectively connected to the floating ball 71 and the baffle 81. The floating ball 71 drives and adjusts the position of the baffle 81 relative to the heat dissipation holes 31 through the water level in the heat dissipation water tank 4 to open and close the heat dissipation holes 31.

[0041] Specifically, during the actual detection process, the low-voltage power metering box 3 generates a large amount of heat and needs to be cooled in time. In the traditional solution, heat is simply dissipated through the heat dissipation holes 31. Not only is the heat dissipation efficiency low, but also in rainy weather, rainwater is likely to enter the low-voltage power metering box 3 through the heat dissipation holes 31 and damage the internal components. In this embodiment, however, dual heat dissipation of the low-voltage power metering box 3 is achieved through the heat dissipation holes 31 and the heat dissipation water pipes 5, greatly improving its heat dissipation efficiency, and thus improving the working stability of the low-voltage power metering box 3. Secondly, the heat dissipation water tank 4 uses the rainwater collected as the coolant, and with the cooperation of the circulation management, the rainwater can be recycled as the coolant, with lower cost, more convenient use, and better heat dissipation effect. In addition, in this embodiment, the floating ball 71 can be used to judge the water level of the rainwater collected in the heat dissipation water tank 4, and thus indirectly sense the amount of rainwater. The floating ball 71 is connected to the baffle 81 through the connecting rod assembly 72. As the water level in the heat dissipation water tank 4 rises, the floating ball 71 will drive the baffle 81 to move upward through the connecting rod assembly 72, so that the baffle 81 blocks the heat dissipation holes 31, thereby closing the heat dissipation holes 31, allowing the low-voltage power metering box 3 to dissipate heat more through the heat dissipation water pipes 5, and at the same time preventing too much rainwater from entering the low-voltage power metering box 3 and damaging the electronic components inside the low-voltage power metering box 3. And in this process, due to the increase in the amount of rainwater, the heat dissipation efficiency of the heat dissipation water pipes 5 will also increase, thus ensuring the normal heat dissipation of the low-voltage power metering box 3. That is, while ensuring the heat dissipation effect of the low-voltage power metering box 3, the protection ability of the low-voltage power metering box 3 is also improved.

[0042] Finally, the low-voltage power metering box 3 can be designed according to the actual experimental requirements and the type of the electricity meter. Since the low-voltage power metering box 3 is a prior art, it will not be elaborated here.

[0043] In some embodiments, the heat dissipation water tank 4 includes a main body 41 fixedly arranged on the top of the support frame 1. The main body 41 is provided with a receiving cavity 42 for receiving rainwater; a rain shield 43 extending outward is arranged on the top of the main body 41, and the rain shield 43 is used to guide rainwater into the receiving cavity 42; a filter plate 44 and a diversion plate 45 are sequentially arranged in the receiving cavity 42 from top to bottom.

[0044] Specifically, the opening of the receiving cavity 42 is arranged on the side of the main body 41 away from the support frame 1, and the main body 41 is provided with a rain shield 43 extending outward around the opening of the receiving cavity 42. On the one hand, the rain shield 43 can expand the rainwater collection range and better collect rainwater into the heat dissipation water tank 4; on the other hand, the rain shield 43 extending outward can also better block rainwater and prevent rainwater from directly hitting the low-voltage power metering box 3 and damaging the electronic components inside the low-voltage power metering box 3. In addition, the filter plate 44 is arranged above the diversion plate. The inner wall of the heat dissipation water tank 4 is provided with a plurality of receiving blocks 46 for stably carrying the filter plate 44, and the filter plate 44 can filter impurities in the rainwater to prevent impurities in the rainwater or large particle dust in the air from entering the heat dissipation water pipe 5 and causing blockage of the heat dissipation water pipe 5. The diversion plate 45 can divert the filtered rainwater to both sides of the heat dissipation water tank 4, so as to ensure that there is enough rainwater entering the heat dissipation water pipe 5 to participate in heat dissipation when the rainwater in the heat dissipation water tank 4 is less, improving the heat dissipation efficiency. In a specific embodiment, the cross section of the diversion plate 45 is triangular.

[0045] In some embodiments, a plurality of heat dissipation water pipes 5 are provided corresponding to the low-voltage power metering box 3. The heat dissipation water pipes 5 are uniformly distributed on the inner wall of the low-voltage power metering box 3 in a curved structure, and both ends of the plurality of heat dissipation water pipes 5 are communicated with the heat dissipation water tank 4 and the circulation pipeline 6.

[0046] Specifically, the heat dissipation water pipes 5 are fixed on the inner wall of the low-voltage power metering box 3 in a curved structure, which can increase the contact area between the heat dissipation water pipes 5 and the low-voltage power metering box 3, thereby improving the cooling effect. In a specific embodiment, the heat dissipation water pipes 5 can be fixed by buckles 51. In addition, a plurality of heat dissipation fins can also be fixed on the surface of the heat dissipation water pipes 5 to further improve the heat dissipation effect of the heat dissipation water pipes 5.

[0047] In some embodiments, the circulation pipeline 6 includes a first circulation pipe 61, a second circulation pipe 62, and a water storage tank 63. The two ends of the first circulation pipe 61 are respectively connected to the heat dissipation water pipe 5 and the water storage tank 63. The two ends of the second circulation pipe 62 are respectively connected to the heat dissipation water tank 4 and the water storage tank 63. A first water pump 631 and a second water pump 632 are provided in the water storage tank 63, and the first water pump 631 and the second water pump 632 are respectively connected to the first circulation pipe and the second circulation pipe.

[0048] Specifically, during actual use, the rainwater in the heat dissipation water tank 4 flows into the heat dissipation water pipe 5 to participate in heat dissipation, and then converges into the first circulation pipe 61. Subsequently, the first water pump 631 pumps the rainwater in the first circulation pipe 61 into the water storage tank 63 for storage. At the same time, the second water pump 632 also pumps the rainwater in the water storage tank 63 into the second circulation pipe 62 and enters the heat dissipation water tank 4 through the second circulation pipe 62, thereby realizing the circulation of the coolant to ensure that the heat dissipation of the low-voltage electric energy meter box 3 can be stably achieved without external rainwater supplement. The first water pump 631 and the second water pump 632 are both in the on state during daily heat dissipation, so that the water in the water storage tank 63 and the heat dissipation water tank 4 is always in a dynamic balance state. In addition, there are multiple heat dissipation water pipes 5 corresponding to the low-voltage electric energy meter box 3. In a specific embodiment, each heat dissipation water pipe 5 is individually connected to the main pipe through a pipeline, and then connected to the heat dissipation water tank 4 through the main pipe. In some other embodiments, the heat dissipation water pipes 5 can also be connected end to end in sequence and finally connect the heat dissipation water tank 4 and the first circulation pipe 61. The number, arrangement direction, and connection direction of the connected heat dissipation water pipes 5 can be designed and selected according to the actual use scenario.

[0049] In some embodiments, the circulation pipeline 6 further includes a valve 65 and a drain pipe 64. The drain pipe 64 is respectively connected to the heat dissipation water pipe 5 and the valve 65.

[0050] The valve 65 includes a drainage box 651, a fixing rod 652, and a sealing block 653. The drainage box 651 is respectively connected to the drain pipe 64 and the first circulation pipe 61. A drain hole 654 is provided at the bottom of the drainage box 651. One end of the fixing rod 652 is connected to the link assembly 72, and a sealing block 653 is provided at the other end of the fixing rod 652. The sealing block 653 is arranged in the drainage box 651 to block and seal the drain hole 654.

[0051] In the actual use process, the problem of excessive rainwater often occurs. At this time, it is necessary to timely discharge the excess rainwater to the outside. Therefore, in this embodiment, a drain pipe 64 and a valve 65 are provided. The water outlet ends of multiple heat dissipation pipes 5 are all connected to the drain pipe 64. After the rainwater participating in heat dissipation converges in the drain pipe 64, it then enters the first circulation pipe 61 through the valve 65 uniformly to participate in the circulation, and the excess rainwater can also be discharged to the outside through the valve 65. Specifically, on a rainy day, the rainwater converges in the heat dissipation water tank 4, and the water level component in the heat dissipation water tank 4 rises. The floating ball 71 is subjected to buoyancy and drives the connecting rod assembly 72 and the fixing rod 652 to move upward, thereby driving the sealing block 653 to move upward in the drainage tank 651. The sealing block 653 is separated from the drainage hole 654. After the water in the drain pipe 64 enters the drainage tank 651 of the valve 65, it will be discharged to the outside through the drainage hole 654 and will not flow into the first circulation pipe 61, thus ensuring that the water in the water storage tank 63 and the heat dissipation water tank 4 is in a balanced state after the rain. When the preset amount of rainwater is discharged, the water level in the heat dissipation water tank 4 drops, the floating ball 71 drops and drives the fixing rod 652 and the sealing block 653 to drop, thereby blocking the drainage hole 654, and the water discharged from the drain pipe 64 continues to enter the first circulation pipe 61 to participate in the heat dissipation circulation. In addition, in a specific embodiment, the valve 65 further includes a sealing ring 655 and a mounting rod. The two ends of the mounting rod are respectively connected to the drainage tank 651 and the mounting bracket 2, thereby fixing the position of the drainage tank 651 and making the position of the drainage tank 651 more stable. The sealing ring 655 is fixed to the fixing rod 652 and is located above the drainage tank 651, and can seal the through hole on the upper surface of the drainage tank 651 to prevent the water in the drainage tank 651 from leaking during the normal water circulation and heat dissipation.

[0052] In some embodiments, the rain shield 8 further includes a guide rod 82 and a guide tube 83. The guide rod 82 is fixedly arranged on the low-voltage electric energy metering box 3, the guide tube 83 is slidably connected with the guide rod 82, and the guide tube 83 is fixedly connected to the baffle 81.

[0053] Specifically, in actual use, when the floating ball 71 drives the baffle 81 to move up and down through the connecting rod assembly 72, it is necessary to limit the moving direction of the baffle 81 to ensure that the baffle 81 can accurately block the closed heat dissipation hole 31. In a specific embodiment, a guide rod 82 is provided on the low-voltage power metering box 3, and the baffle 81 is connected to a guide tube 83. By sleeving the guide tube 83 on the guide rod 82, the moving direction of the baffle 81 can be limited, so that the baffle 81 can only move along the axis direction of the guide rod 82. Further, the low-voltage power metering box 3 is provided with two parallel guide rods 82, and both ends of the baffle 81 are connected with guide tubes 83. The two guide tubes 83 are respectively sleeved on the corresponding guide rods 82, which can further limit the rotation of the baffle 81. Fixed blocks 85 are provided at both ends of the guide rod 82 to limit the moving range of the guide tube 83 and prevent the guide tube 83 from detaching from the guide rod 82. In addition, in another specific embodiment, two opposite chutes can be provided at the low-voltage power metering box 3 to limit the moving direction of the baffle 81 through the chutes.

[0054] In some embodiments, there are multiple corresponding heat dissipation holes 31 and baffles 81. The guide tube 83 is fixedly connected with a splicing rod 84, and the splicing rod 84 is fixedly connected with multiple baffles 81.

[0055] Specifically, multiple heat dissipation holes 31 can better dissipate heat from the low-voltage power metering box 3. Naturally, multiple baffles 81 in the rain shield 8 should be provided corresponding to the heat dissipation holes 31. The multiple baffles 81 are connected together by a splicing rod 84. The side of the splicing rod 84 away from the baffle 81 is fixedly connected with a guide tube 83. By sleeving the guide tube 83 on the guide rod 82, multiple baffles 81 can be driven to move synchronously and the moving directions of the multiple baffles 81 can be limited. In addition, a sealing member, such as a sealing ring, is also provided on the side of the baffle 81 facing the heat dissipation hole 31. Through the sealing member, the sealing effect between the baffle 81 and the heat dissipation hole 31 can be better guaranteed, and further prevent rainwater from entering the interior of the low-voltage power metering box 3 from the heat dissipation hole 31.

[0056] In some embodiments, two floating balls 71 are symmetrically arranged along the length direction of the heat dissipation water tank 4. The connecting rod assembly 72 includes a connecting rod 721 and a trigger rod group 722. Both ends of the connecting rod 721 are respectively connected to the two floating balls 71. One end of the trigger rod group 722 is fixedly connected to the connecting rod 721, and the trigger rod group 722 is fixedly connected with multiple rain shields 8.

[0057] Specifically, the minimum number of float balls 71 is two, and they are arranged on both sides of the heat dissipation water tank 4 and above the filter plate 44. The connecting rod 721 is of a U-shaped structure. The two ends of the connecting rod 721 are respectively connected to the two float balls 71. Through the structure of the two float balls 71 and the connecting rod 721, the trigger rod group 722 can be stably driven to move up and down according to the water level, so as to ensure the smoothness and stability of the up and down movement of the baffle 81. Secondly, in actual use, since there are multiple rain shields 8 provided corresponding to the low-voltage electric energy metering box 3, the trigger rod group 722 needs to be connected to drive multiple rain shields 8 at the same time. Therefore, the trigger rod group 722 includes multiple rods. In a specific embodiment, the trigger rod group 722 is divided into upper and lower parts. The upper part is T-shaped and fixedly connected to multiple upper baffles 81, while the lower part is L-shaped and fixedly connected to multiple baffles 81 on one side below. Of course, in other embodiments, the specific structure of the trigger rod group 722 can be designed according to the number and distribution position of the low-voltage electric energy metering boxes 3, which will not be elaborated here.

[0058] In addition, in a specific embodiment, the rain shield 43 on the top of the heat dissipation water tank 4 is provided with two overflow grooves corresponding to the connecting rod 721. When the water level in the heat dissipation water tank 4 is too high, the water in the heat dissipation water tank 4 can also overflow to the outside through the overflow grooves, avoiding excessive rainwater flowing into the upper part of the low-voltage electric energy metering box 3. At the same time, the two ends of the connecting rod 721 also slide in the corresponding overflow grooves, and the overflow grooves can play a role in limiting the connecting rod 721 to prevent the connecting rod 721 from shifting during the up and down movement.

[0059] In some embodiments, the trigger member 7 further includes a limiting rod 73 and a limiting block 74. The limiting rod 73 is fixed to the heat dissipation water tank 4, and the connecting rod 721 is slidably connected to the limiting rod 73. The limiting block 74 is fixed to the bottom end of the limiting rod 73.

[0060] Specifically, the connecting rod 721 is provided with through holes corresponding to the limiting rod 73, and the limiting rod 73 is inserted into the through holes so that the connecting rod 721 can be slidably connected to the limiting rod 73. The limiting block 74 can limit the movement of the connecting rod 721 to prevent the connecting rod 721 from detaching from the connection with the limiting rod 73, thereby preventing the connecting rod 721 from shifting during the up and down movement.

[0061] In some embodiments, a first electrode 75 is provided on one side of the connecting rod 721 facing the limiting block 74, and a second electrode 76 is provided on one side of the limiting block 74 facing the connecting rod 721. The first electrode 75 and the second electrode 76 are used to control the operating states of the first water pump 631 and the second water pump 632.

[0062] Specifically, when the water level drops and the float 71 and the connecting rod 721 move downward, the first electrode 75 and the second electrode 76 come into contact, and the first water pump 631 and the second water pump 632 are turned on to perform a circulating heat dissipation operation. When the water level rises, the float 71 and the connecting rod move upward, and the first electrode 75 and the second electrode 76 are separated, thereby turning off the first water pump 631 and the second water pump 632, and the rainwater collected in the heat dissipation water tank 4 is used for heat dissipation. The rainwater after heat dissipation is directly discharged to the outside through the drainage hole 654 of the valve 65. On the one hand, energy is saved, and on the other hand, the problem of rainwater accumulation in the heat dissipation water tank 4 in heavy rain is solved. In addition, the outside rainwater is used for heat dissipation throughout the process instead of circulating water, and the overall heat dissipation effect will be better.

[0063] In summary, the embodiment of the present invention provides an electric energy meter reliability detection device, which determines rainy weather by whether the float 71 floats up or down, and drives multiple baffles 81 to move up and down through the trigger rod group 722 to open and close the heat dissipation holes 31 of the low-voltage electric energy meter box 3, so as to avoid rainwater splashing into the low-voltage electric energy meter box 3 and causing damage when the rain is heavy. At the same time, the heat dissipation water tank 4 can also be used to receive rainwater as the coolant of the low-voltage electric energy meter box 3, which is lower in cost and more convenient and quick to use. In addition, the setting of the drainage hole 654 in the valve 65, the sealing block 653 and the fixing rod 652 can discharge excess rainwater in heavy rainy weather, avoid rainwater overflow and damage the low-voltage electric energy meter box 3, and realize intelligent adjustment of the water level in the heat dissipation water tank 4.

[0064] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
