Therefore, their waterproof performance is crucial. To ensure the stable operation of intelligent electricity meters under various weather conditions, professional waterproof performance testing tooling is needed for detection; The working principle of the intelligent electricity meter waterproof testing tooling currently used in the market is to spray water on the electricity meter to form a rain curtain, which can evenly cover the surface of the intelligent electricity meter. This design is to simulate the real situation in the outdoor environment, that is, raindrops fall on the electricity meter box from various directions, so as to test whether the waterproof performance of the intelligent electricity meter meets the standard; However, in actual applications, if water seepage occurs inside the electricity meter test box, it is very difficult for staff to detect these minor water seepage problems with the naked eye. In this case, the existence of water seepage problems will directly affect the accuracy and effect of the intelligent electricity meter waterproof test, which may lead to inaccurate evaluation of the waterproof performance and pose potential risks to subsequent use and maintenance.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.
[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description of the present invention can be used in other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present invention.
[0024] Those skilled in the art should understand that in the disclosure of the present invention, the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position relationship shown in the drawings. It is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.
[0025] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.
[0026] Embodiment 1: Please refer to Figure 1 - Figure 14 , an intelligent electricity meter reliability test tooling, comprising: a water tank 1 and a test box 2 fixed on the water tank 1; further comprising: a carrier plate 3 arranged in the test box 2, an electricity meter body 4 is placed on the carrier plate 3, and a positioning mechanism 5 is arranged on the carrier plate 3, the positioning mechanism 5 is used for positioning the electricity meter body 4 before the waterproof performance test, a spraying unit 6 is arranged on the water tank 1, the spraying unit 6 is used for simulating the rain weather environment, and; a swinging mechanism 7 installed on the water tank 1, the swinging mechanism 7 is used for adjusting the showering angle and height of the electricity meter body 4, and a water seepage tank is opened on the top surface of the water tank 1 to ensure that the used water source can smoothly flow back into the water tank. It should be noted that through the setting of the positioning mechanism 5, the accurate clamping and positioning of the meter body 4 can be realized, so as to ensure that the meter body 4 can maintain a relatively stable state during the waterproof test work. This process is crucial for ensuring the accuracy and reliability of the test. Then, the spraying unit 6 simulates a realistic rain weather condition to conduct a comprehensive and detailed waterproof test on the meter body 4. By simulating rains with different intensities and directions, it is ensured that the meter can maintain its performance unaffected under various harsh weather conditions. In addition, in order to further enhance the authenticity and comprehensiveness of the test, a swinging mechanism 7 and a lifting mechanism 34 are adopted to simulate the rain weather condition. Through simulating the swing and impact of the rain, a more stringent waterproof performance test is carried out on the meter body 4. This comprehensive test method can ensure that the meter can demonstrate excellent waterproof performance when facing the challenges of the natural environment in actual applications.
[0027] Furthermore, the spraying unit 6 includes: a submersible pump 21 is fixed on the inner side wall of the test box 2 through a support frame 20. A semi-circular spray pipe 22 is rotatably connected to the test box 2. The output end of the submersible pump 21 is fixed with a docking water pipe 23, and the other end of the docking water pipe 23 extends into the semi-circular spray pipe 22. At least two installation grooves 24 are opened on the test box 2, and a fan 25 is fixed in the installation grooves 24. Through the setting of the fan 25, various situations of the rain weather can be more accurately simulated. This can not only enhance the accuracy of the waterproof performance test work of the meter body 4, but also ensure that the test results are closer to the performance in the actual use environment. Among them, the swinging mechanism 7 includes: a servo motor 26 is fixed on the water tank 1. A shaft body 27 coaxially fixed with the servo motor 26 is rotatably connected to the water tank 1. A runner 28 is fixed on the shaft body 27. A sector gear 30 is rotatably connected to the water tank 1 through a rotating rod 29. A guiding frame 31 is fixed on the sector gear 30. A transmission rod 32 slidably connected in the guiding frame 31 is fixed on the runner 28. A spur gear 33 is fixed on the semi-circular spray pipe 22, and the spur gear 33 is meshed and connected with the sector gear 30. Specifically, a lifting mechanism 34 adapted to the swinging mechanism 7 is arranged on the test box 2. The lifting mechanism 34 includes: a reciprocating lead screw 35 is rotatably connected to the water tank 1. The reciprocating lead screw 35 and the shaft body 27 are meshed and driven through two bevel gears 36. A pipe sleeve 37 is fixed on the water tank 1. The reciprocating lead screw 35 is rotatably connected in the pipe sleeve 37. A channel 38 communicating with the inside is opened on the pipe sleeve 37. A nut sleeve 39 is threadedly connected to the reciprocating lead screw 35. A bracket 40 slidably connected in the channel 38 is fixed on the nut sleeve 39. A bearing plate 41 is fixed on the bracket 40. In addition, at least two mounting frames 44 are fixed on the water tank 1. Guide rods 45 are fixed on the mounting frames 44. The bracket 40 is slidably penetrated between the guide rods 45. A spring a46 is fixed to the bottom surface of the bearing plate 3. The other end of the spring a46 is fixedly provided with a buffer ring 47, and the buffer ring 47 is located directly above the sleeve 37. By sliding the bracket 40 on the surface of the guide rod 45, it can play a guiding role for the bracket 40 to ensure that the movement of the bracket 40 remains relatively stable. With the elastic action of the buffer ring 47 and the spring a46, it can prevent the bearing plate 3 from colliding and damaging with the sleeve 37 when the bearing plate 3 moves downward; It should be noted that through the swinging mechanism 7, the semi-circular water spray pipe 22 can be driven to perform regular reciprocating swinging actions. The purpose of this action is to more realistically simulate the rain weather conditions encountered during the waterproof test of the electricity meter body 4. In addition, through the setting of the lifting mechanism 34, the electricity meter body 4 can be driven to perform regular reciprocating lifting movements. This movement method enables the electricity meter body 4 to experience the water receiving situation of gradually increasing and decreasing, thereby effectively improving the test effect of the waterproof performance of the electricity meter body 4 and being able to simulate a more real rain weather to conduct the waterproof test of the electricity meter body 4.
[0028] Working principle of the swinging mechanism 7 and the lifting mechanism 34: Driven by the servo motor 26, the shaft body 27 rotates synchronously, driving the runner 28 to rotate synchronously, causing the transmission rod 32 to rotate synchronously around the runner 28. By using the extrusion transmission effect of the transmission rod 32 in the guiding frame 31, the guiding frame 31 and the sector gear 30 perform reciprocating swinging along the axis of the rotating rod 29. By using the meshing transmission effect between the sector gear 30 and the spur gear 33, the semi-circular water spray pipe 22 can be driven to perform reciprocating swinging. By using the meshing transmission effect between the two bevel gears 36, the reciprocating lead screw 35 rotates synchronously. By using the meshing transmission effect between the reciprocating lead screw 35 and the screw sleeve 39, the bracket 40 is driven to move up and down reciprocally in the channel 38 after being stressed, realizing driving the electricity meter body 4 to move up and down reciprocally.
[0029] It is worth noting that the shell of the electricity meter body 4 is divided into a bottom box and a face cover. The bottom box is used to accommodate the internal components of the electricity meter, and the face cover covers the bottom box to form a closed space. This is a conventional setting in this field, so it will not be elaborated in detail here.
[0030] The working process of the waterproof reliability test of the electricity meter body 4 in this solution: First, disassemble the shell of the electricity meter body 4, place the bottom box and the face cover on one side of the anhydrous copper sulfate test paper 54 respectively, and install the bottom box and the face cover, so that the anhydrous copper sulfate test paper 54 remains inside the shell of the electricity meter body 4. Place the assembled electricity meter body 4 on the support plate 11, and the positioning mechanism 5 clamps and positions the electricity meter body 4; Secondly, driven by the submersible pump 21, the water source in the water tank 1 is pumped and pressurized. The water source after pumping and pressurization is conveyed to the semi-circular water spray pipe 22 through the docking water pipe 23. The semi-circular water spray pipe 22 sprays water towards the electricity meter body 4. Driven by the fan 25, the generated wind is sent into the test box 2 to form a simulated rain weather condition; Then, through the cooperation of the swinging mechanism 7 and the lifting mechanism 34, while driving the semi-circular water spray pipe 22 to swing reciprocally, the electricity meter body 4 is driven to move up and down reciprocally, so as to simulate a more realistic rain weather environment; Finally, after spraying water on the electricity meter body 4, rotate the operating wheel 10 to release the limit on the electricity meter body 4, and then the electricity meter body 4 can be disassembled. Check the state of the anhydrous copper sulfate test paper 54 inside the shell of the electricity meter body 4. If the color of the anhydrous copper sulfate test paper 54 changes, it means that there is water seepage in the electricity meter body 4. If the anhydrous copper sulfate test paper 54 does not change color, it means that the waterproof performance of the electricity meter body 4 is qualified.
[0031] Example 2: Refer to Figure 9 - Figure 11 As shown, this embodiment further illustrates the example, and the difference lies in disclosing a way to clamp and position the electricity meter body 4.
[0032] Furthermore, the positioning mechanism 5 includes: a mounting frame 8 fixed on the bearing plate 3. A screw rod 9 is rotatably connected to the mounting frame 8, and an operating wheel 10 is fixed at one end of the screw rod 9. A support plate 11 is fixed on the mounting frame 8. The electricity meter body 4 is in contact with the support plate 11. A plurality of symmetrically distributed sliding grooves 12 are formed on the mounting frame 8. A mounting rod 13 is slidably connected in the sliding groove 12. A clamping plate 14 slidably connected to the mounting frame 8 is fixed on the mounting rod 13. A screw sleeve 15 slidably connected in the mounting frame 8 is threadedly connected to the screw rod 9. A connecting rod 16 is hinged between the screw sleeve 15 and the mounting rod 13. A plurality of circumferentially distributed sliding rods 42 are fixed on the bearing plate 3. An annular groove 43 is formed on the load-bearing plate 41. The sliding rods 42 are slidably connected in the annular groove 43. The central axis of the load-bearing plate 41 is collinear with the central axis of the bearing plate 3. The vertical cross-sections of the sliding rods 42 and the annular groove 43 are both in an inverted T shape, which not only ensures that the bearing plate 3 can rotate around the center of the load-bearing plate 41 after being stressed, but also can prevent the bearing plate 3 from shifting during rotation, facilitating the adjustment of the angular position of the bearing plate 3, and then facilitating the staff to install the electricity meter body 4 for waterproof testing; Among them, a plurality of symmetrically distributed guiding grooves 17 are formed on the mounting frame 8, and a guiding rod 18 is fixed on the clamping plate 14. The guiding rod 18 is slidably connected in the guiding groove 17. The opening length values of the guiding groove 17 and the sliding groove 12 are the same. A guiding groove 19 is formed in the mounting frame 8. The screw sleeve 15 is slidably connected in the guiding groove 19; Specifically, by adding the guiding groove 17 and the guiding rod 18, the stability of the clamping plate 14 during the force-induced movement can be significantly improved, effectively preventing the displacement phenomenon that may occur during the movement of the clamping plate 14. At the same time, through the opened guiding groove 19, the guiding function of the screw sleeve 15 is further enhanced, ensuring that the screw sleeve 15 can also maintain sufficient stability during the movement, thereby improving the reliability and precision of the overall work; It should be noted that through the setting of the positioning mechanism 5, the simultaneous clamping and precise positioning of the two meter bodies 4 can be achieved. This design not only has wide applicability and can easily handle meter bodies 4 of different sizes, but also can effectively avoid the risk of the meter body 4 falling due to shaking or improper operation during the waterproof test work of the meter body 4. Therefore, the positioning mechanism 5 performs particularly well in ensuring the clamping and positioning effect of the meter body 4; The positioning principle of the meter body 4 using the positioning mechanism 5: Place the meter body 4 on the support plate 11 and ensure that the meter body 4 is in contact with the installation frame 8. By rotating the operation wheel 10, the screw rod 9 rotates synchronously. Utilizing the threaded transmission between the screw rod 9 and the screw sleeve 15, the screw sleeve 15 moves along the guiding groove 19 under force. Using the transmission of the connecting rod 16, the clamping plate 14 moves along the sliding groove 12 under force until the two clamping plates 14 clamp the meter body 4 tightly.
[0033] Example Three: Refer to Figure 6 - Figure 8 As shown, this embodiment further illustrates the example, and the difference lies in disclosing a method of using anhydrous copper sulfate test paper 54 for testing the waterproof performance of the meter body 4.
[0034] Among them, an auxiliary test component 48 is arranged on the bearing plate 3. The auxiliary test component 48 includes: a storage box 49 fixed on the bearing plate 3, several hollow tubes 50 fixed on the storage box 49, a spring b 51 fixed inside the hollow tube 50, a push plate 52 fixed at the other end of the spring b 51 and slidably connected to the inner side of the storage box 49, several mounting plates 53 placed in the storage box 49, anhydrous copper sulfate test paper 54 fixed on the mounting plates 53, a frame 55 fixed on the bearing plate 3, a through groove 56 for the mounting plate 53 to pass through is jointly opened between the frame 55 and the storage box 49, a sealing cover plate 57 is rotatably connected to the storage box 49 through a hinge, and an elastic buckle is added between the sealing cover plate 57 and the storage box 49 to realize the positioning of the sealing cover plate 57; Specifically, at least two push rods 58 penetrate through the storage box 49 in a sliding manner. A rod body 59 is fixedly connected to the two push rods 58. A spring c 60 is sleeved on the push rod 58. One end of the spring c 60 is fixed to the rod body 59, and the other end of the spring c 60 is fixed to the outer side wall of the storage box 49. A limiting groove 61 for the sliding of the mounting plate 53 is formed on the frame 55, and the limiting groove 61 communicates with the through groove 56. After the anhydrous copper sulfate test paper 54 on the frame 55 has been used, by manually pulling the mounting plate 53 until it is separated from the limiting groove 61. When it is necessary to use the anhydrous copper sulfate test paper 54 again for the waterproof test, by pressing the rod body 59, the two push rods 58 move synchronously into the storage box 49. At this time, the spring c 60 is in a compressed state. The rod body 59 is used to drive the mounting plate 53 by extrusion, so as to drive the mounting plate 53 to move into the through groove 56 until the mounting plate 53 is pushed into the limiting groove 61. Manually pull the mounting plate 53 into the limiting groove 61 until it reaches the appropriate position, which is convenient for the next use of the anhydrous copper sulfate test paper 54 to perform the waterproof test on the meter body 4. It should be noted that anhydrous copper sulfate has strong water absorption. When it comes into contact with water, a chemical reaction will occur to generate copper sulfate pentahydrate, which is blue. Therefore, the test paper will change from white to blue, thus intuitively indicating the presence of water. The color change from white to blue is very obvious and easy to observe even in a relatively dark environment, which is convenient for the tester to accurately judge whether the electric energy meter has water ingress, so as to realize the waterproof performance test of the smart electric meter. This is a conventional setting in this field, so it will not be elaborated in detail here. It should be noted that after the waterproof test of the meter body 4 is completed, if it is found that all the anhydrous copper sulfate test papers 54 in the storage box 49 have been used up, at this time, the storage box 49 can be reorganized and prepared by simply flipping the sealing cover plate 57. The specific operation is to place the unused mounting plates 53 with anhydrous copper sulfate test papers 54 in the storage box 49 in sequence, which can facilitate the next waterproof test. When a new test is required, only the mounting plate 53 close to the through groove 56 needs to be pulled out. By using the elastic force of the spring b 51, the next mounting plate 53 with an anhydrous copper sulfate test paper 54 can be automatically reset to a position close to the through groove 56, thus ensuring the continuity and efficiency of the test work.
[0035] The servo motor 26, the fan 25 and the submersible pump 21 can all be purchased on the market. The servo motor 26, the fan 25 and the submersible pump 21 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the description.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and without departing from the said principles, any variations or modifications can be made to the embodiments of the present invention.
