[0022] Specifically, the support base 31 is composed of an upper support base and a lower support base. The lower support base is provided with universal wheels on the side facing the ground. The number of universal wheels can be increased or decreased according to actual conditions. In this embodiment, the number of universal wheels is three. Figure 6 He Ru Figure 7 As shown, a third power source 311, a fifth gear 312 and a sixth gear 313 are provided on the side of the upper support base facing the lower support base. The third power source 311 provides power to the fifth gear 312 through gear transmission. The fifth gear 312 and the sixth gear 313 are meshed with each other. The sixth gear 313 is fixed to one end of the upper support base close to the lower support base. Multiple guide rail support beams 33 are connected to each other at both ends and are installed in a rectangular shape on the upper end of the support base 31. It should be noted that the guide rail support beam 33 at the upper end and the guide rail support beam 33 at the lower end are fixedly installed in the guide rail support beam 33 on the left and the guide rail support beam 33 on the right. Fixed installation includes welding and clamping. A camera 61 is provided on the guide rail support beam 33 at the upper end. The camera 61 is detachably connected to the guide rail support beam 33 through a connecting piece, and the camera 61 is rotatably connected to the connecting piece 61.

[0023] The camera 61 can collect information of different environments, different directions, different shapes, and different angles of the cabinet, and transmit it to the display screen through internal sensors and control modules. Slide grooves are provided on the left and right guide rail support beams 33. The guide rail reinforcement beam 32 is provided on the side of the guide rail support beam 33 away from the connecting plate 22. It should be noted that in this embodiment, the guide rail reinforcement beam 32 is installed on the left guide rail support beam 33, the right guide rail support beam 33, and the guide rail support beam 33 at the lower end.

[0024] The transmission assembly includes a power assembly and a plurality of gear transmission assemblies; the gear transmission assembly includes a fixed frame 41, a worm wheel 42, a worm 43, a third gear 44 and a fourth gear 45; the worm wheel 42 is arranged in the fixed frame 41, the worm 43 passes from one end of the fixed frame 41 to the other end and meshes with the worm wheel 42, the third gear 44 and the fourth gear 45 are arranged at the upper end of the fixed frame 41, the third gear 44 is sleeved on the worm 43 and meshes with the fourth gear 45, one end of the lead screw 25 is sleeved on the fourth gear 45, and the plurality of gear transmission assemblies are fixedly connected to the power assembly through a rotating shaft 46.

[0025] like Figure 2 He Ru Figure 3 As shown, the transmission assembly is installed on one side of the support assembly, and the second power source 51 is welded to the upper end of the support base 31 through a bracket. A shock-absorbing rubber ring is arranged on one side of the second power source 51 and is installed on the bracket. The elastic deformation of the rubber absorbs part of the vibration energy, thereby playing a role in shock absorption and noise reduction, and reducing the impact of vibration and noise on the spray device. A driving gear 52 is arranged on the other side of the second power source 51. The driving gear 52 and the driven gear 53 are meshed with each other. The driving gear 52 is installed on the output shaft of the second power source 51, and the driving gear 52 is a small gear. The driven gear 53 is a relatively large gear compared to the driving gear. When the small gear drives the large gear to rotate, the small gear has fewer teeth and a faster rotation speed, while the large gear has more teeth and a relatively slower rotation speed. The speed change can be achieved through the meshing of the small gear and the large gear.

[0026] In this embodiment, there are two gear transmission assemblies, each of which includes a fixed frame 41, a worm wheel 42, a worm 43, a third gear 44 and a fourth gear 45. The worm wheel 42 is arranged in the fixed frame 41, and a rotating shaft 46 is sleeved in the driven gear 53. The rotating shaft 46 passes through the fixed frame 41 and the worm wheel 42. The worm 43 passes from the upper end to the lower end of the fixed frame 41 and is meshed with the worm wheel 42. The third gear 44 is sleeved on the worm 43. The third gear 44 and the fourth gear 45 are installed on the fixed frame 41, and the third gear 44 and the fourth gear 45 are meshed with each other. The lead screw 25 is sleeved on the fourth gear 45.

[0027] like Figure 4 He Ru Figure 5 As shown, the lifting assembly includes a guide rail 21, a connecting plate 22, a guide rail pulley 23, a lead screw tooth groove 24, and a lead screw 25. The guide rail pulley 23 is slidably connected to the slide groove on the guide rail support beam 33. The guide rail pulley 23 is threadedly connected to the connecting plate 22 by bolts or screws. The middle and lower ends of the connecting plate 22 are fixed by the guide rail 21, and the upper end is connected by a rotating assembly. A lead screw tooth groove 24 is provided on one side of the guide rail 21 close to the transmission assembly. The lead screw tooth grooves 24 in the same vertical direction are a group, and the number of groups is adapted to the number of gear transmission assemblies. In this embodiment, there are four lead screw tooth grooves 24, two in each group, and each lead screw tooth groove 24 is provided with a through hole. The lead screw 25 passes through the through hole and is detachably connected to the fourth gear 45.

[0028] The lead screw 25 is mounted on the fourth gear 45. The power output of the fourth gear 45 causes the lead screw 25 to rotate. The forward and reverse rotation of the lead screw 25 causes the lead screw tooth groove 24 to move up and down. The lead screw tooth groove 24 is mounted on the guide rail 21, causing the guide rail 21 to move up and down. The up and down movement of the guide rail 21 drives the connecting plate 22 to move up and down, causing the spray shower 15 to move in the same direction. The lead screw 25 converts the rotary motion into a linear motion.

[0029] like Figure 5 As shown, the rotating assembly is installed at the upper end of the guide rail 21, including a first gear 11, a second gear 12, a bearing sleeve 13, a roller 14 and a shower head 15. The first gear 11 is powered by a first power source to rotate, and the first power source is fixedly installed on the connecting plate 22. The first gear 11 and the second gear 12 are meshed with each other. The second gear 12 is sleeved on the outer ring of the bearing sleeve 13. The bolts pass from one end of the bearing sleeve 13 to the other end and are threadedly connected to the connecting plate 22. The two ends of the roller 14 pass through the second gear 12 bearing sleeve 13 from the inside to the outside, and the shower head 15 is welded on the roller 14. The bearing sleeve 13 has the advantages of good wear resistance, good stability, easy installation, reduced friction and noise, wide application, and solving assembly and disassembly problems.

[0030] The first power source, the second power source 51, and the third power source 311 are all stepper motors, and each motor operates independently without affecting each other. In addition, the first power source can independently control the spray shower 15 to rotate 0-360 degrees; the second power source 51 can independently control the spray shower 15 to move up and down; the third power source 311 can independently control the spray shower 15 to rotate 0-360 degrees. When the spray shower 15 moves up and down, it can also rotate. Both are carried out at the same time, so that every surface of the charging pile can be sprayed with water.

[0031] Example 2 A spraying method for a charging pile includes the following steps: the first gear 11 and the second gear 12 are meshed with each other to drive the roller 14 to rotate, and the roller 14 drives the spray shower 15 to rotate; the lifting component drives the spray shower 15 to move up and down.

[0032] Specifically, the driving gear 52 is installed on the output shaft of the second power source 51. The second power source 51 reduces the vibration and noise generated by the second power source 51 during operation through a shock-absorbing rubber ring. Since the driving gear 52 and the driven gear 53 are meshed with each other, the driving gear 52 transmits the force output by the second power source 51 to the driven gear 53. The driven gear 53 is connected to the worm wheel 42 through the rotating shaft 46, and the worm wheel 42 and the driven gear 53 keep rotating in the same direction. The worm wheel 42 and the worm 43 are meshed with each other, and the worm 43 changes the direction of the force output by the second power source 51. The third gear 44 is sleeved on the worm 43, and the third gear 44 and the worm 43 keep rotating in the same direction. The fourth gear 45 and the third gear 44 are meshed with each other. One end of the lead screw 25 is sleeved on the fourth gear 45, so that the lead screw 25 and the third gear 44 keep rotating in the same direction. The lead screw 25 passes through the through hole in the lead screw tooth groove 24, the lead screw tooth groove 24 is fixedly connected to the guide rail 21, the guide rail 21 and the roller 14 on the guide rail 21 are connected to the connecting plates 22 on both sides, and the up and down movement of the lead screw 25 causes the spray shower 15 on the roller 14 to move up and down in the same direction as the lead screw 25.

[0033] The first power source is installed on one side of the connecting plate 22, the first gear 11 is installed on the output shaft of the first power source, the first gear 11 and the second gear 12 are meshed with each other, the second gear 12 is sleeved on the bearing sleeve 13, the bearing sleeve 13 is installed on the side of the connecting plate 22 away from the guide pulley 23, the bearing sleeve 13 is fixed to the connecting plate 22 by bolts or screws, the roller 14 passes through the second gear 12 and is clamped with the bearing sleeve 13, and the spray shower 15 is fixedly installed on the roller 14, where the fixing is welding, and the fixed connection includes threaded connection, key connection, pin connection, interference connection, welding, and riveting. Threaded connection is a common fixed connection method, which realizes the connection of two or more parts by screwing together. This connection method has the advantages of simple structure, easy manufacturing and assembly, and easy disassembly and adjustment. Key connection is to connect two parts together by a key to realize the function of axial fixation and torque transmission. Key connection is divided into four types: flat key connection, semicircular key connection, wedge key connection and tangential key connection. Among them, semicircular keys, wedge keys, tangential keys, and ordinary flat keys and thin flat keys among flat keys all belong to fixed connections. Key connection has the advantages of simple structure, reliable operation, and convenient assembly and disassembly. Pin connection is to connect two parts together through pins to achieve the function of fixing or positioning. Pin connection has the advantages of simple structure, easy manufacturing and assembly. Interference connection is to achieve connection through interference fit between two parts. This connection method has the advantages of simple structure, high load-bearing capacity, and not easy to loosen. Welding is to melt and connect two parts together by heating to achieve the function of fixed connection. Welding has the advantages of high connection strength and good sealing, but it cannot be disassembled. Riveting is to connect two parts together through rivets to achieve the function of fixed connection. Riveting has the advantages of reliable connection and high load-bearing capacity. In summary, the first power source controls the rotation of the spray shower 15 through the first gear 11, the second gear 12, and the roller 14.

[0034] The third power source 311 provides power output for the fifth gear 312, the fifth gear 312 meshes with the sixth gear 313, and the sixth gear is installed in the support base 31, and controls the support base 31 to rotate, thereby driving the upper spray shower 15 to rotate in the same direction. By controlling the first power source and the third power source 311 to make the spray shower rotate 0-360°, and controlling the second power source 51 to make the spray shower produce different displacements, it can meet the full range of water spray tests for charging pile cabinets of different heights and depths without being limited by the size of the cabinet.
