[0026] The following description, with reference to the accompanying drawings, describes an outdoor simulated rainwater spraying experimental device for a new energy charging pile according to an embodiment of this application.

[0027] Please see Figures 1-3 and Figure 7 An outdoor simulated rainwater spraying experimental device for new energy charging piles according to an embodiment of this application includes: a container section 10, a spraying section 20, and a water supply section 30.

[0028] The spray section 20 is installed inside the container section 10 and is supplied with water through the water supply section 30. The spray section 20 can adjust the spray density to simulate the impact of different density rainfall on the charging pile, which can further enrich the simulation experimental data of the charging pile.

[0029] The box room part 10 comprises a box room shell 110, the spray part 20 comprises a center box 210, a horizontal movement adjusting assembly 220, a first spray head 230, a second spray head 240, a hydraulic adjusting assembly 250 and a flow guide pipe 260.

The moving distance of the first spray head 230 is increased or decreased in a geometric progression larger than that of the second spray head 240, and the hydraulic adjusting assembly 250 is installed outside the box room shell 110. The water supply part 30 comprises a water bucket 310, a water pump 320, a first connecting pipe 360 and a second connecting pipe 370. The first connecting pipe 360 is connected to a plurality of first spray heads 230, the second connecting pipe 370 is connected to a plurality of second spray heads 240, and the water bucket 310 is connected to the water pump 320 through a water inlet pipe 330. The water pump 320 is connected to the first connecting pipe 360 through a water outlet pipe 340, and the water outlet pipe 340 is connected to the first connecting pipe 360 through a branch pipe 350. The branch pipe 350 is provided with a second electric pressure regulating valve 351, and the water outlet pipe 340 is provided with a first electric pressure regulating valve 341 behind the branch pipe 350.

[0030] The working principle of the new energy charging pile outdoor simulated rainwater spraying experimental device is as follows: the new energy charging pile to be tested is placed directly below the center box 210 inside the box room shell 110. The water pump 320 draws water from the water bucket 310 through the water inlet pipe 330, and the pressurized water is pumped into the first spray head 230 through the water outlet pipe 340 and the first connecting pipe 360. The liquid passing through the first electric pressure regulating valve 341 at the tail end of the water outlet pipe 340 can be adjusted in water pressure through the first electric pressure regulating valve 341, that is, the spraying water pressure of the first spray head 230 is adjusted. The liquid passing through the water outlet pipe 340 pressurized by the water pump 320 is partially diverted through the branch pipe 350 and sprayed from the second spray head 240 through the second connecting pipe 370. The liquid passing through the second electric pressure regulating valve 351 in the branch pipe 350 can be adjusted in water pressure through the second electric pressure regulating valve 351, that is, the spraying water pressure of the second spray head 240 is adjusted, and different rainfall amounts are simulated.

[0031] When it is necessary to simulate rainwater density, the hydraulic adjusting assembly 250 and the flow guide pipe 260 are matched to adjust the hydraulic pressure inside the horizontal movement adjusting assembly 220, so as to adjust the distance between the first spray head 230 and the second spray head 240. Different density rainfalls can be simulated by the first spray head 230 cooperating with the second spray head 240. On this basis, the first electric pressure regulating valve 341 and the second electric pressure regulating valve 351 are matched to simultaneously adjust the density and the rainfall amount, so as to simulate more types of rainwater conditions for spraying experiments.

[0032] The first connecting pipe 360 and the second connecting pipe 370 are connected by flexible pipes, and the first connecting pipe 360 and the second connecting pipe 370 reserve the maximum length of the flexible pipes.

[0033] In the above embodiment, the box room part 10 further comprises a base 120 and a box door 130, the box door 130 is arranged at one end of the box room shell 110, and the box room shell 110 is fixed above the base 120. A longitudinal drainage groove 140 is arranged on the upper surface of the base 120 close to the box door 130. The water produced by the spraying in the box room shell 110 is drained through the drainage groove 140.

[0034] Please refer to Figure 2 and Figure 6 The new energy charging pile outdoor simulation rainwater spraying experimental device further comprises a wind simulation part 40, the wind simulation part 40 comprises a box shell 410, a return air pipe 420, a wind cover shell 430 and a fan 440. A plurality of wind cover shells 430 are connected and fixed at the end of the box room shell 110 away from the box door 130, the fan 440 is installed in the wind cover shell 430, one end of the return air pipe 420 is connected and arranged with the top of the box room shell 110, the other end of the return air pipe 420 is connected and arranged with the box shell 410, and the box shell 410 is connected and installed at the back of the wind cover shell 430. The wind simulation part 40 further comprises a mesh plate 450, and the mesh plate 450 is arranged at the port of the wind cover shell 430.

[0035] The wind cover shell 430 and the fan 440 are arranged in multiple groups. The start and stop of each group of fans 440 and the exhaust volume can be controlled individually, which is used to simulate the rainwater sprayed by the spraying part 20 to the outside of the charging pile under different wind speed conditions. That is, the data between the experimental conditions of no ventilation wind speed and wind volume and the rainwater and the charging pile.

[0036] Specifically, please refer to Figure 4 and Figure 5The horizontal movement adjusting assembly 220 comprises a horizontal seat strip plate 221, a first piston block 223, a second piston block 226, a first horizontal frame 224 and a second horizontal frame 227. The center box 210 is internally provided with a first piston cavity 222 and a second piston cavity 225 in communication with the center box 210, the inner diameter of the first piston cavity 222 is smaller than that of the second piston cavity 225, the first piston block 223 is slidingly arranged inside the first piston cavity 222 and connected with the first nozzle 230 through the first horizontal frame 224, and the second piston block 226 is slidingly arranged inside the second piston cavity 225 and connected with the second nozzle 240 through the second horizontal frame 227. The center box 210 is provided with water outlets 211 on the side, and the two water outlets 211 are respectively arranged in communication with the first piston cavity 222 and the second piston cavity 225. The hydraulic pressure adjusting assembly 250 comprises a liquid storage tank 251, a piston plate 252, a threaded rod 253, a threaded sleeve 254 and a hand wheel 255. The liquid storage tank 251 is fixedly arranged outside the box house shell 110, the bottom end of the flow guide pipe 260 is arranged in communication with the liquid storage tank 251, the piston plate 252 is movably arranged inside the liquid storage tank 251, the threaded sleeve 254 is fixed at one end of the liquid storage tank 251, one end of the threaded rod 253 is rotatably arranged with the piston plate 252, and the other end of the threaded rod 253 is screw-connected with the threaded sleeve 254, and the hand wheel 255 is installed at the end of the threaded rod 253 away from the piston plate 252.

[0037] The specific adjustment mode between the hydraulic pressure adjusting assembly 250 and the horizontal movement adjusting assembly 220 is that by rotating the hand wheel 255 in the hydraulic pressure adjusting assembly 250, the rotating hand wheel 255 drives the threaded rod 253 to rotate, and when the rotating threaded rod 253 is screw-connected with the threaded sleeve 254, the piston plate 252 will also be synchronously driven to move along the axial position of the threaded rod 253, the piston plate 252 can adjust the liquid amount in the internal cavity between the liquid storage tank 251 and the piston plate 252, through the communication arrangement between the flow guide pipe 260 and the inside of the center box 210, the liquid amount in the inside of the center box 210 will also change, that is, the liquid amount in the inside of the first piston cavity 222 and the second piston cavity 225 through the water outlets 211 will also change due to the pressure. Since the inner diameter of the first piston cavity 222 is smaller than that of the second piston cavity 225, the inner diameter of the second piston cavity 225 can be 1.5 times that of the first piston cavity 222. That is, the first piston block 223 in the inside of the first piston cavity 222 and the second piston block 226 in the inside of the second piston cavity 225 will move synchronously, the moving distance of the first piston block 223 is always larger than that of the second piston block 226, so as to realize the linear transformation of the distance between the first nozzle 230 and the second nozzle 240. When the first nozzle 230 and the second nozzle 240 simulate rainfall, the overlapping part of the water amount sprayed by the first nozzle 230 and the second nozzle 240 is adjusted, that is, different rainfall densities are simulated.

[0038] In a specific setting, the water supply part 30 further comprises a chassis 311 fixedly arranged at the bottom of the water bucket 310, and the chassis 311 is used to support the water bucket 310. The water supply part 30 further comprises a vertical cylinder pipe 380, the bottom end of the vertical cylinder pipe 380 extends to the inside of the water bucket 310 through the top wall of the water bucket 310, and the top of the vertical cylinder pipe 380 is communicatively provided with a feeding bin 390. The sea salt is added to the inside of the water bucket 310 through the vertical cylinder pipe 380 from the feeding bin 390, and is mixed with the water source in the inside of the water bucket 310, and is sprayed out through the first spray head 230 and the second spray head 240, which can simulate the high-salt water spraying in the seaside area on the charging pile, the corrosion, sealing and other influence conditions of the charging pile.

[0039] The above-mentioned new energy charging pile outdoor simulation rainwater spraying experimental device is difficult to quickly and uniformly dissolve the added sea salt in the inside of the water bucket 310 during simulation, which affects the uniformity of the salt water during spraying and the precision of the experimental data of the spraying simulation.

[0040] Please refer to Figure 7 and Figure 8 The new energy charging pile outdoor simulation rainwater spraying experimental device further comprises a rapid mixing part 50, the rapid mixing part 50 comprises a drainage shell 510 with an open bottom, a main roller 520, an auxiliary roller 530, a driving motor 540, a disc 550, a leaf plate 560 and a block plate 570. The top of the drainage shell 510 is fixedly connected to the bottom end of the vertical cylinder pipe 380, and the main roller 520 and the auxiliary roller 530 are arranged in parallel inside the drainage shell 510. The end of the main roller 520 is rotatably connected to the water bucket 310, the driving motor 540 is installed outside the water bucket 310, and the shaft end of the driving motor 540 is connected to one end of the main roller 520. The disc 550 is fixedly and obliquely arranged outside the end rod of the main roller 520, a plurality of leaf plates 560 are arranged in a ring shape outside the disc 550, the block plate 570 is fixedly arranged inside the leaf plate 560, and the discs 550 on the two end rods of the main roller 520 are symmetrically and obliquely arranged.

[0041] The sea salt is added through the feeding bin 390, and the added sea salt enters the inside of the flow guide shell 510 through the vertical cylinder pipe 380. The inside of the flow guide shell 510 is provided with an inclined guide plate, so that the sea salt falling from the vertical cylinder pipe 380 is guided between the main roller 520 and the auxiliary roller 530. The driving motor 540 drives the main roller 520 to rotate, and the outer surfaces of the main roller 520 and the auxiliary roller 530 can have good grinding lines. The sea salt falling between the main roller 520 and the auxiliary roller 530 is crushed and ground by the cooperation of the rotating main roller 520 and the auxiliary roller 530. The main roller 520 and the auxiliary roller 530 rotate towards each other when crushing and grinding the sea salt, and the ground sea salt falls from the bottom of the flow guide shell 510. When the driving motor 540 drives the main roller 520 to rotate, the inclined disc 550 at the end of the main roller 520 rotates synchronously. The rotating disc 550 synchronously rotates the external leaf plate 560 and the block plate 570. Since the disc 550 is inclined, the overall coverage space is larger when the disc 550 rotates the leaf plate 560 and the block plate 570, which can cause greater turbulence and improve the dispersion efficiency of the sea salt in the water bucket 310. The two groups of discs 550 and the external leaf plates 560 are symmetrically arranged, and when the leaf plate 560 below the disc 550 is close to the bottom of the flow guide shell 510, the sea salt particles falling from the bottom of the flow guide shell 510 can be better disturbed and mixed with the water source in the water bucket 310, thereby improving the mixing efficiency of the sea salt in the box shell 410. The leaf plate 560 and the block plate 570 are vertically arranged, so that when the leaf plate 560 rotates, the block plate 570 can better disturb the water source in the water bucket 310, and quickly and efficiently mix the sea salt put into the water bucket 310.

[0042] The application also provides an embodiment that one group of the first spray head 230 and the second spray head 240 is designed as an atomizing spray head. The salt mist and high-salt rainwater sprayed by the first spray head 230 and the second spray head 240 can be simulated, and the salt mist and high-salt rainwater mixed spray simulation can simulate the erosion of the salt mist and high-salt rainwater on the charging pile under different conditions, especially for the charging pile put in the seaside area, which can provide more convenient and accurate experimental data.

[0043] The above-mentioned outdoor simulation rainwater spraying experimental device for new energy charging pile only uses the rotating grinding mode of the main roller 520 and the auxiliary roller 530 to crush the sea salt into smaller particles, which is difficult to realize rapid and efficient crushing and crushing of the sea salt.

[0044] Please refer to Figure 8 and Figure 9The new energy charging pile outdoor simulated rain water spraying experimental device further comprises an auxiliary pressing part 60, the auxiliary pressing part 60 comprises a pressing roller 610, an end shaft 620, an elastic sleeve 640, a bearing 650 and a vibration motor 660. The pressing roller 610 is located above the middle part of the main roller 520 and the auxiliary roller 530, the end shaft 620 is fixed at the end of the pressing roller 610, the bearing 650 is sleeved outside the end shaft 620, the elastic sleeve 640 is fixedly sleeved outside the bearing 650 and is fixedly arranged with the drainage shell 510, the inside of the pressing roller 610 is provided with an inner cavity 630, and the vibration motor 660 is installed inside the inner cavity 630.

[0045] The sea salt discharged from the feeding bin 390 falls into the inside of the drainage shell 510 through the vertical cylinder pipe 380, and after being guided by the inclined guide plates on both sides of the inside of the drainage shell 510, the sea salt will fall in the area between the auxiliary roller 530, the main roller 520 and the pressing roller 610. The driving motor 540 will drive the main roller 520 to rotate, and the cooperation between the main roller 520 and the auxiliary roller 530 can extrude the ground sea salt. While the main roller 520 rotates to grind the sea salt with the auxiliary roller 530, the vibration motor 660 inside the inner cavity 630 will drive the pressing roller 610 to vibrate. The elastic sleeve 640 at both ends of the pressing roller 610 plays a buffering role. When the sea salt between the main roller 520, the auxiliary roller 530 and the pressing roller 610 is relatively dense, through the friction force provided by the sea salt in the space, the rotating main roller 520 will drive the pressing roller 610 to rotate by the friction force of the sea salt to roll the sea salt, so that the sea salt can be crushed. While the pressing roller 610 rolls, the vibration motor 660 inside the inner cavity 630 drives the pressing roller 610 to vibrate, and the cooperation between the outer surface of the pressing roller 610 and the main roller 520 and the auxiliary roller 530 extrudes the sea salt, that is, extrudes and rubs the sea salt at the same time, so that the sea salt can be ground efficiently and fall out of the bottom of the drainage shell 510, thereby improving the grinding efficiency of the sea salt and the uniformity of the mixing rate of the sea salt and the concentration of the sea salt in the inside of the water bucket 310.

[0046] When the vibration motor 660 drives the pressing roller 610 to vibrate, the elastic sleeve 640 at the end of the pressing roller 610 plays a damping and buffering role, and the elastic sleeve 640 can be made of a rubber material with good elasticity.
