Description

Technical Field

[0001] This application relates to the field of charging pile testing technology, and in particular to charging pile aging testing equipment. Background Technology

[0002] As frequently used outdoor electrical equipment, charging piles are exposed to complex environments such as wind, sun, and rain for extended periods. The anti-aging performance of their outer shell and internal components directly affects the equipment's lifespan and operational safety. Therefore, it is essential to conduct targeted testing using professional anti-aging testing equipment. During the testing process, the equipment continuously or intermittently sprays water onto the surface of the charging pile through a specific device, accurately simulating rainy weather in the natural environment. This verifies the sealing performance of the charging pile's outer shell, the material's resistance to water corrosion, and the stability of the internal circuitry in humid environments. This comprehensive assessment of its anti-aging capabilities under long-term rain exposure provides data support for the quality improvement and safe operation of charging piles.

[0003] The charging pile testing and aging device mentioned in the existing patent (authorization announcement number: CN221993550U) uses telescopic rods A, B, and C, and a push plate. First, telescopic rod A is extended to its maximum length. To prevent it from tipping over during movement, a clamp is used to fix the charging pile to the push plate. Then, it is moved to a designated position. Next, telescopic rod A is shortened to move the guide rod to one side of the charging pile. Then, telescopic rod B is retracted to allow the charging pile to enter the simulation chamber. After the test, telescopic rod C is retracted, and then telescopic rod A is extended again to push the charging pile out of the simulation chamber. This prevents some charging piles with poor waterproof performance from leaking electricity after the test and avoids testers from coming into contact with the simulated environment inside the aging device after the test. After being removed by the guide mechanism, it can be observed to make a preliminary judgment on whether there is any obvious water leakage problem in the charging pile.

[0004] However, in actual use, after the existing charging pile anti-aging testing equipment is completed, a large amount of residual moisture will adhere to the surface of the charging pile. When the staff removes it from the equipment, this moisture will drip uncontrollably everywhere, which will not only wet the ground of the testing site, surrounding instruments and cables, increasing the difficulty of site cleaning and the risk of equipment getting damp, but also make the surface of the charging pile shell slippery. When the staff takes it out of the testing equipment, they are prone to slipping and may cause the charging pile to be bumped and damaged. Summary of the Invention

[0005] The purpose of this application is to address the problem mentioned in the background art that after the test is completed, a large amount of residual water will adhere to the surface of the charging pile, and the water will drip everywhere, which will not only wet the ground of the test site, surrounding instruments and cables, increasing the difficulty of site cleaning and the risk of equipment getting damp, but also make the surface of the charging pile shell slippery, which may cause the charging pile to be bumped and damaged. This application provides a charging pile aging test device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A charging pile aging test device includes a main body with a test chamber and a drying chamber inside. Protective doors are installed on the main body at positions corresponding to the test chamber and drying chamber. A controller is fixed to the side of the main body. A mesh belt conveyor is installed inside the main body. A water collection tank is located at the bottom of the test chamber, and an air outlet is located inside the drying chamber. A material passage is provided between the test chamber and the drying chamber. The mesh belt conveyor passes through the material passage to connect the test chamber and the drying chamber. A simulation structure for simulating charging pile testing is provided on one side of the main body, and a drying structure for drying the charging pile is provided on the other side of the main body.

[0007] By adopting the above technical solution, the charging pile to be tested is placed on a mesh belt conveyor. A simulated rain-weather aging test is then conducted on the charging pile. After the test, the tested charging pile is transported to the drying chamber via the mesh belt conveyor, where it is dried using a drying structure. After drying, the protective door of the drying chamber is opened, and the dried charging pile is removed. (Drying structure) Furthermore, the simulation structure includes a water storage tank fixed to the side of the main body of the equipment, an outlet pipe fixed to the upper end of the water storage tank, a nozzle fixed to the end of the outlet pipe away from the water storage tank, the nozzle extending into the test chamber, an inlet pipe fixed to the side of the water storage tank, the end of the inlet pipe away from the water storage tank extending into the water receiving tank, and a pump installed on both the outlet pipe and the inlet pipe, the pump being electrically connected to the controller.

[0008] By adopting the above technical solution, during the test, the pump on the water outlet pipe is turned on to draw water out of the water tank and spray it out through the nozzle. The sprayed water falls on the charging pile, thereby simulating the anti-aging performance of the charging pile in a long-term rainy weather scenario.

[0009] Furthermore, the drying structure includes a drying box fixed on the side of the equipment body away from the water storage tank. The drying box is equipped with a drying component. A sealing side plate is fixed on the side of the drying box. An air inlet is opened at the bottom of the drying box. A conveying pipe is fixed at the upper end of the drying box. The end of the conveying pipe away from the drying box extends into the drying chamber and is fixed with a corrugated hose. An air outlet pipe is fixed at the end of the corrugated hose away from the conveying pipe. A swing component is provided between the air outlet pipe and the drying chamber.

[0010] By adopting the above technical solution, the drying structure can dry the surface of the charging pile after testing, which can effectively reduce the problem of water dripping everywhere when the charging pile is taken out after testing, thus reducing the impact on the surrounding environment. It can also effectively reduce the problem of slipping when taking out the charging pile due to water on its surface.

[0011] Furthermore, the drying assembly includes a drive motor fixed to the side of the drying chamber, the drive motor being electrically connected to the controller, a drive shaft being fixed to the output end of the drive motor, the end of the drive shaft away from the drive motor extending into the drying chamber and being rotatably connected to the drying chamber, and an impeller being fixed on the drive shaft.

[0012] By adopting the above technical solution, the drying component is used to blow air into the drying chamber to dry the charging pile.

[0013] Furthermore, an installation frame is fixed inside the drying oven, and a resistance heating wire is fixed inside the installation frame. The resistance heating wire is electrically connected to the controller.

[0014] By adopting the above technical solution, the resistance heating wire is used to heat the air, thereby enabling hot air to be blown into the drying chamber.

[0015] Furthermore, the oscillating assembly includes a bidirectional lead screw rotatably connected inside the drying chamber, one end of the bidirectional lead screw extending out of the drying chamber, a movable plate sleeved on the bidirectional lead screw, the movable plate being connected to the bidirectional lead screw via a nut seat, and the air outlet pipe passing through the movable plate and being fixedly connected to the movable plate.

[0016] By adopting the above technical solution, the swing component is used to drive the air outlet pipe to move back and forth left and right inside the drying chamber, so as to increase the air blowing range and thus improve the drying effect.

[0017] Furthermore, a guide rod is fixed inside the drying chamber, and the movable plate is slidably sleeved on the guide rod.

[0018] By adopting the above technical solution, the guide rod plays a guiding and supporting role, enabling the air outlet pipe to move smoothly inside the drying chamber.

[0019] Furthermore, a first pulley is fixed on the drive shaft, and a second pulley is fixed at one end of the bidirectional screw extending out of the drying chamber. The first pulley and the second pulley are connected by a transmission belt.

[0020] By adopting the above technical solution, the cooperation of the first pulley, the transmission belt, and the second pulley can achieve the function of transmission.

[0021] Furthermore, a hydraulic telescopic rod is fixed inside the material passage, the hydraulic telescopic rod is electrically connected to the controller, and a sealing plate is fixed to the telescopic end of the hydraulic telescopic rod, the sealing plate being slidably disposed between the material passage and the material passage.

[0022] By adopting the above technical solution, during testing, the hydraulic telescopic rod drives the sealing plate to move downward, which can play a blocking role and reduce the amount of water entering the drying chamber during the testing process.

[0023] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when drying the tested charging pile, the drive motor and resistance heating wire are turned on. When the drive motor is working, the drive shaft rotates and drives the impeller to rotate. The rotation of the impeller can accelerate the air flow inside the drying chamber, and send the outside air into the drying chamber through the air inlet at the bottom of the drying chamber. When the resistance heating wire is working, it generates heat, which can heat the air inside the drying chamber. The heated air is sent into the conveying pipe, then into the corrugated hose, and finally blown out through the air outlet. The blown hot air comes into contact with the tested charging pile, and the hot air can dry the water attached to the surface of the charging pile. This can effectively reduce the problem of water attached to the surface of the charging pile dripping everywhere when the charging pile is removed after testing, which would affect the surrounding environment.

[0024] 2. At the same time, by drying the water on the surface of the charging pile, the problem of the charging pile slipping and falling when it is taken out can be effectively reduced due to the water on the surface of the charging pile.

[0025] 3. When the drive shaft drives the impeller to rotate and dry the water adhering to the surface of the charging pile, the first pulley, the transmission belt, and the second pulley drive the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, the moving plate is subjected to force and is restricted and guided by the guide rod. Together with the nut seat, the moving plate drives the air outlet pipe to reciprocate left and right on the bidirectional lead screw. The swing assembly causes the air outlet pipe to reciprocate left and right inside the drying chamber, thereby enabling air blowing and drying of different locations on the charging pile, increasing the drying range and thus improving drying efficiency.

[0026] 4. At the same time, the reciprocating moving air outlet can effectively prevent the air outlet from blowing hot air towards the same position of the charging pile, which would cause excessive heat accumulation in the local area of ​​the charging pile and overheating. It can also prevent other areas with less airflow from not drying properly, thus improving the drying effect on the charging pile. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses an aging test device for charging piles.

[0031] Reference Figure 1 , Figure 2 , Figure 5 The charging pile aging test equipment includes a main body 1, which has a test chamber 11 and a drying chamber 12 inside. Protective doors 13 are installed on the main body 1 at positions corresponding to the test chamber 11 and the drying chamber 12. A controller 14 is fixed to the side of the main body 1. A mesh belt conveyor 15 is installed inside the main body 1. The mesh belt conveyor 15 can be a DR-SS conveyor, and different models of conveyors can be used according to actual needs. A water collection tank 16 is opened at the bottom of the test chamber 11. During the test, the water falling will enter the water collection tank 16 for subsequent reuse. An air outlet 17 is opened inside the drying chamber 12. A material passage 18 is opened between the test chamber 11 and the drying chamber 12. The mesh belt conveyor 15 passes through the material passage 18 to connect the test chamber 11 and the drying chamber 12. A simulation structure for simulating the test of the charging pile is set on one side of the main body 1, and a drying structure for drying the charging pile is set on the other side of the main body 1.

[0032] The simulation structure includes a water tank 2 fixed to the side of the main body 1 of the equipment. A water outlet pipe 21 is fixed to the upper end of the water tank 2. A nozzle 22 is fixed to the end of the water outlet pipe 21 away from the water tank 2. The nozzle 22 extends into the test chamber 11. A water inlet pipe 23 is fixed to the side of the water tank 2. The end of the water inlet pipe 23 away from the water tank 2 extends into the water receiving tank 16. A pump 24 is installed on both the water outlet pipe 21 and the water inlet pipe 23. The pump 24 on the water inlet pipe 23 is used to pump water from the water receiving tank 16 into the water tank 2 for reuse. The pump 24 is electrically connected to the controller 14.

[0033] The material passage 18 is equipped with a hydraulic telescopic rod 4, which is electrically connected to the controller 14. A sealing plate 41 is fixed to the telescopic end of the hydraulic telescopic rod 4. The sealing plate 41 is slidably disposed between the material passage 18 and the material passage 18. A flexible rubber pad is fixed to the bottom of the sealing plate 41. When the charging pile is tested, the telescopic end of the hydraulic telescopic rod 4 extends, causing the sealing plate 41 to move downward, so that the flexible rubber pad at the bottom of the sealing plate 41 fits against the mesh belt conveyor 15, thereby effectively reducing the amount of spray water entering the drying chamber 12 during the test.

[0034] During the testing of the charging pile, the protective door 13 at the test chamber 11 is opened, and the charging pile is placed on the mesh belt conveyor 15 at the position corresponding to the nozzle 22. The protective door 13 is then closed, and the extraction pump 24 on the water outlet pipe 21 is turned on to extract water from the water tank 2. The water then flows through the water outlet pipe 21 into the nozzle 22 and is sprayed out, landing on the charging pile to simulate the anti-aging performance of the charging pile in a long-term rainy weather scenario. After 15-20 minutes of simulated testing, the extraction pump 24 is turned off by the controller, and the hydraulic telescopic rod 4 is opened to retract. During the retraction, the sealing plate 41 rises, and then the mesh belt conveyor 15 operates, transporting the tested charging pile into the drying chamber 12. The tested charging pile is then dried by the drying structure. After drying, the protective door 13 at the drying chamber 12 is opened, and the dried charging pile is removed.

[0035] Reference Figures 2-4 The drying structure includes a drying box 3 fixed on the side of the main body 1 away from the water storage tank 2. The drying box 3 is equipped with a drying component. A sealing side plate 31 is fixed on the side of the drying box 3. An air inlet is opened at the bottom of the drying box 3. A conveying pipe 32 is fixed at the upper end of the drying box 3. The end of the conveying pipe 32 away from the drying box 3 extends into the drying chamber 12 and is fixed with a corrugated hose 33. The corrugated hose 33 is a TPU plastic corrugated hose with high temperature resistance and fatigue resistance. An air outlet pipe 34 is fixed at the end of the corrugated hose 33 away from the conveying pipe 32. A swing component is provided between the air outlet pipe 34 and the drying chamber 12.

[0036] The drying assembly includes a drive motor 35 fixed to the side of the drying chamber 3. The drive motor 35 is electrically connected to the controller 14. A drive shaft 351 is fixed to the output end of the drive motor 35. The end of the drive shaft 351 away from the drive motor 35 extends into the drying chamber 3 and is rotatably connected to the drying chamber 3. An impeller 352 is fixed on the drive shaft 351.

[0037] In addition, a mounting frame 353 is fixed inside the drying oven 3, and a resistance heating wire 354 is fixed inside the mounting frame 353. The resistance heating wire 354 is electrically connected to the controller 14.

[0038] When drying the tested charging pile, the controller 14 turns on the drive motor 35 and the resistance heating wire 354. When the drive motor 35 is working, it drives the drive shaft 351 to rotate. The rotation of the drive shaft 351 drives the impeller 352 to rotate. The rotation of the impeller 352 can accelerate the air flow inside the drying chamber 3, and send the outside air into the drying chamber 3 through the air inlet at the bottom of the drying chamber 3. When the resistance heating wire 354 is working, the surface temperature of the resistance heating wire 354 can reach 55℃-60℃, which can heat the air inside the drying chamber 3. The heated air is sent into the conveying pipe 32, and then into the corrugated hose 33. Finally, it is blown out through the air outlet 34. The blown hot air comes into contact with the tested charging pile. The hot air can dry the water attached to the surface of the charging pile, which can effectively reduce the problem of water attached to the surface of the charging pile dripping everywhere when the charging pile is removed after testing, and the impact on the surrounding environment. Meanwhile, by drying the water on the surface of the charging pile, the problem of the charging pile slipping and falling when it is taken out can be effectively reduced due to the water on the surface.

[0039] After continuously drying the charging pile with hot air for 5 minutes, observe the drying status of the charging pile and determine whether to continue drying based on the drying status, until the surface moisture of the charging pile is completely dried. When the charging pile is dried, turn off the resistance heating wire 354 so that it no longer heats the air inside the drying chamber 3. At this time, the air outlet pipe 34 blows air to cool down the charging pile. After cooling down for 3 minutes, the charging pile can be taken out, which can effectively reduce the problem of burns caused by the surface temperature of the charging pile being too high due to drying.

[0040] Reference Figures 2-4 The oscillating assembly includes a bidirectional lead screw 36 rotatably connected inside the drying chamber 12. One end of the bidirectional lead screw 36 extends out of the drying chamber 12. A movable plate 361 is sleeved on the bidirectional lead screw 36. The movable plate 361 is connected to the bidirectional lead screw 36 through a nut seat. An air outlet pipe 34 passes through the movable plate 361 and is fixedly connected to the movable plate 361.

[0041] The drying chamber 12 has a guide rod 362 fixed inside, and the movable plate 361 is slidably sleeved on the guide rod 362.

[0042] In addition, a first pulley 363 is fixed on the drive shaft 351, and a second pulley 364 is fixed at one end of the bidirectional lead screw 36 extending out of the drying chamber 12. The first pulley 363 and the second pulley 364 are connected by a transmission belt 365.

[0043] When the drive shaft 351 drives the impeller 352 to rotate to dry the water adhering to the surface of the charging pile, the first pulley 363 on the drive shaft 351 will rotate accordingly. Then, under the action of the transmission belt 365, the second pulley 364 will rotate. When the second pulley 364 rotates, it drives the bidirectional lead screw 36 to rotate. When the bidirectional lead screw 36 rotates, the moving plate 361 is subjected to force and is restricted and guided by the guide rod 362. With the help of the nut seat, the moving plate 361 drives the air outlet pipe 34 to move back and forth on the bidirectional lead screw 36. The swing assembly makes the air outlet pipe 34 move back and forth inside the drying chamber 12, thereby blowing air to dry different positions of the charging pile, increasing the drying range and thus improving the drying efficiency. Moreover, the reciprocating moving air outlet pipe 34 can effectively prevent the air outlet pipe 34 from blowing hot air towards the same position of the charging pile, which would cause excessive heat accumulation in some areas of the charging pile and overheating. It can also prevent other areas with less airflow from not drying properly, thus improving the drying effect of the charging pile.

[0044] Working principle: When testing the charging pile, open the protective door 13 at the test chamber 11, place the charging pile on the mesh belt conveyor 15 at the position corresponding to the nozzle 22, then close the protective door 13, and then turn on the extraction pump 24 on the water outlet pipe 21 to extract the water from the water tank 2 and let it enter the nozzle 22 through the water outlet pipe 21. The water sprayed out through the nozzle 22 will fall on the charging pile, thereby simulating the anti-aging performance of the charging pile in a long-term rainy weather scenario. After the test is completed, turn off the extraction pump 24 and turn on the hydraulic telescopic rod 4 to retract it. When it retracts, it drives the sealing plate 41 to rise. Then the mesh belt conveyor 15 will work to transport the tested charging pile into the drying chamber 12. After testing, the charging piles are dried. During drying, the drive motor 35 and the resistance heating wire 354 are activated by the controller 14. When the drive motor 35 is working, it drives the drive shaft 351 to rotate. The rotation of the drive shaft 351 drives the impeller 352 to rotate. The rotation of the impeller 352 can accelerate the air flow inside the drying chamber 3, and send the outside air into the drying chamber 3 through the air inlet at the bottom of the drying chamber 3. When the resistance heating wire 354 is working, the surface temperature of the resistance heating wire 354 can reach 55℃-60℃, which can heat the air inside the drying chamber 3. The heated air is sent into the conveying pipe 32, and then into the corrugated hose 33. Finally, it is blown out through the air outlet 34. The blown hot air comes into contact with the tested charging piles. The hot air can dry the water attached to the surface of the charging piles, which can effectively reduce the problem of water dripping everywhere when the charging piles are removed after testing, thus reducing the impact on the surrounding environment. Meanwhile, by drying the water on the surface of the charging pile, the problem of the charging pile slipping and falling when it is taken out can be effectively reduced due to the water on the surface of the charging pile. When the drive shaft 351 drives the impeller 352 to rotate to dry the water adhering to the surface of the charging pile, the first pulley 363 on the drive shaft 351 will rotate accordingly. Then, under the action of the transmission belt 365, the second pulley 364 will rotate. When the second pulley 364 rotates, it drives the bidirectional lead screw 36 to rotate. When the bidirectional lead screw 36 rotates, the moving plate 361 is subjected to force and is restricted and guided by the guide rod 362. With the help of the nut seat, the moving plate 361 drives the air outlet pipe 34 to move back and forth on the bidirectional lead screw 36. The swing assembly makes the air outlet pipe 34 move back and forth inside the drying chamber 12, thereby blowing air to dry different positions of the charging pile, increasing the drying range and thus improving the drying efficiency. Moreover, the reciprocating moving air outlet pipe 34 can effectively prevent the air outlet pipe 34 from blowing hot air towards the same position of the charging pile, which would cause excessive heat accumulation in some areas of the charging pile and overheating. It can also prevent other areas with less airflow from not drying properly, thus improving the drying effect of the charging pile.

[0045] After continuously drying the charging pile with hot air for 5 minutes, observe the drying progress and determine whether to continue drying until the surface moisture of the charging pile is completely dry. Once the charging pile is dry, turn off the resistance heating wire 354 to stop heating the air inside the drying chamber 3. At this time, the air outlet 34 will blow air to cool the charging pile. After cooling for 3 minutes, remove the charging pile. This effectively reduces the risk of burns caused by excessively high surface temperature during drying. After drying is complete, open the protective door 13 at the drying chamber 12 and remove the charging pile.
