Description

Technical Field

[0001] The present invention belongs to the technical field of charging piles and relates to a manual spraying device and method for a charging pile. Background Art

[0002] Globally, the reserves of traditional energy sources such as coal and oil are decreasing, and the energy crisis is gradually becoming prominent. At the same time, environmental problems such as exhaust emissions caused by the large-scale use of fuel vehicles are becoming more and more serious. For example, greenhouse gas emissions lead to global warming and reduced air quality, which have brought many adverse effects on the ecological environment and human health. Electric vehicles use electricity as a power source and basically do not produce exhaust emissions during driving. They have significant environmental advantages and can effectively alleviate the pressure on the environment in the transportation field. They are in line with the current trend of green and sustainable development, so their development prospects are very broad.

[0003] In the waterproof test of existing charging pile cabinets, water spraying operation on the cabinet is mainly carried out by manual handheld water spraying devices. It is necessary to constantly change the angle and adjust the distance around the charging pile cabinet, and move the position of the cabinet multiple times to ensure that all sides and corners of the cabinet can be sprayed with water, simulating the actual situations that may be encountered such as water impact from different directions and immersion in accumulated water. However, it is difficult to ensure the uniformity and comprehensiveness of water spraying and the consistency of each test through manual operation.

[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] Example 1 A manual spray device for a charging pile of the present invention comprises: a hand wheel 1, a rotating unit, a spray unit and a box 2; the rotating unit comprises a first bevel gear 3, a second bevel gear 4, a transmission shaft 5, a driving gear 6, a transmission gear 7, a driven gear 8, a guide shaft 9, a base 10, a gear shaft 11 and an adjusting shaft 12.

[0023] Specifically, Figure 1 As shown, the manual spray device for the charging pile includes a box body 2, which is composed of a support frame, a bottom wall, a top wall and at least one side wall. The top wall and the bottom wall are arranged at the upper and lower ends of the support frame, and the top wall and the bottom wall are welded to the support frame or detachably connected by screws or bolts. Universal wheels 27 are arranged at the lower end of the box body 2, and multiple universal wheels are respectively installed at the four corners of the support frame and connected to the bottom wall to facilitate the movement of the entire device.

[0024] like Figure 2As shown, a protective cover 25 is provided in the box body 2, and the guide shaft 9 passes through the protective cover 25 for installing the spray unit. The protective cover 25 is installed on the outside of the rotating unit. During the spraying process of the spray head in the spray unit, the protective cover 25 is used for protection to reduce water from entering the rotating unit and affecting the transmission accuracy. The spray unit can be installed inside the support frame or on the upper end of the top wall.

[0025] like Figure 3 As shown, the rotating unit includes a handwheel 1, and the hand crank on the handwheel 1 is held to rotate the handwheel 1. One end of the adjusting shaft 12 is connected to the output end of the handwheel 1, and the other end is embedded in the first bevel gear 3, so that when the handwheel 1 rotates, the first bevel gear 3 and the handwheel 1 keep rotating in the same direction, and the second bevel gear 4 is arranged at the lower end of the first bevel gear 3. At the same time, the second bevel gear 4 and the first bevel gear 3 are meshed with each other to change the transmission direction of the handwheel 1.

[0026] The second bevel gear 4 is sleeved on the upper end of the transmission shaft 5, the driving gear 6 is sleeved on the lower end of the transmission shaft 5, and the lower end of the transmission shaft 5 is welded to the base 10, and the connection is smooth and burr-free, ensuring that the contact surface between the driving gear 6 and the base 10 is maximized and meshes with the transmission gear 7. The fixed bracket 23 is sleeved on the transmission shaft 5 and is located between the second bevel gear 4 and the driving gear 6. The side wall of the fixed bracket 3 is fixedly connected to the box body 2, and the screw bolt passes through the side wall of the box body 2 and is threadedly connected to the fixed bracket 23.

[0027] The second bevel gear 4 synchronously transmits the changed transmission direction to the driving gear 6, and the driving gear 6 is meshed with the driven gear 8 through the transmission gear 7. The transmission gear 7 is sleeved on the outside of the gear shaft 11, and the lower end of the gear shaft 11 is welded to the base 10. The driven gear 8 is sleeved on the outside of the guide shaft 9, and the lower end of the guide shaft 9 is also welded to the base 10. The transmission shaft 5, the gear shaft 11, and the guide shaft 9 can be an integrated structure with the base 10, and the base 10 is installed on the upper end of the bottom wall of the box body 2 and fixed.

[0028] like Figure 4 As shown, a limit stopper 24 is provided on one side of the upper end of the base 10 close to the driven gear 8. When the driven gear 8 rotates too fast, the limit stopper 24 prevents it from rotating further, thereby playing a protective role.

[0029] The transmission shaft 5 and the guide shaft 9 are also sleeved with a seal 22, which is located at the upper end of the driving gear 6 or the upper end of the driven gear 8 to prevent liquid (such as water) from entering the driving gear 6 or the driven gear 8 from the outside, and can protect against damage from pollutants such as moisture and dust.

[0030] To sum up, the first bevel gear 3 drives the second bevel gear 4 to rotate through the rotation of the handwheel 1, the second bevel gear 4 is installed on the transmission shaft 5, the driving gear 6 drives the transmission gear 7 to rotate through the gear meshing transmission mode, the transmission gear 7 drives the driven gear 8 to rotate through the gear meshing mode, the driven gear 8 and the spray unit are both installed on the guide shaft 9 to realize coaxial transmission, and the spray unit is rotated by rotating the handwheel 1.

[0031] Example 2 The spray unit includes a guide shaft support 13 , a fixed base 14 , an operating wheel 15 , a third bevel gear 16 , a fourth bevel gear 17 , a rolling wheel 18 and a clamping assembly. The clamping assembly includes a spray shower 19 , a support base 20 and a delivery pipe 21 .

[0032] like Figure 5 As shown, the guide shaft support 13 is T-shaped as a whole, and the guide shaft support 13 is provided with a first through hole in the vertical direction and a second through hole in the horizontal direction, and the first through hole is used to install the guide shaft 9. A gap is provided on the left side of the first through hole, and is connected to the first through hole, so that it can be installed on guide shafts 9 of different diameters. The bolt passes through the second through hole and is threadedly connected with the nut to further fix the guide shaft support 13 and the guide shaft 9 to prevent loosening.

[0033] A fixed base 14 is provided on the right side of the guide shaft support 13, and the fixed base 14 and the guide shaft support 13 are connected by clamping, threading, or welding. Figure 6 As shown, the fixed base 14 is L-shaped as a whole, one side is connected to the guide shaft support 13, and the other side is used to install the third bevel gear 16 and the fourth bevel gear 17. The third bevel gear 16 is installed at the output end of the control wheel 15, the input end of the rolling wheel 18 is connected to the fourth bevel gear, and the output end is connected to the support seat 20.

[0034] The third bevel gear 16 and the fourth bevel gear 17 are fixed to the fixed base 14 through a fixing frame. At the same time, a certain distance is left between the third bevel gear 16 and the upper end surface of the fixed base 14 to ensure mutual meshing with the fourth bevel gear 17. The fourth bevel gear 17 and the third bevel gear 16 are similar.

[0035] A protective cover 26 is provided on the fixed base 14 to protect the third bevel gear 16 and the fourth bevel gear 17 to prevent liquid from entering the outer surface of the third bevel gear 16 or the fourth bevel gear 17 during the operation of the shower head 19, thereby affecting the transmission effect. The gear transmission has high precision and can be controlled in real time.

[0036] In summary, the control wheel 15 is manually rotated, and the control wheel 15 causes the third bevel gear 16 to rotate in the same direction during the rotation process. The third bevel gear 16 and the fourth bevel gear 17 are meshed with each other, and the transmission direction is changed. The fourth bevel gear 17 rotates the clamping assembly through the rolling wheel 18 during the rotation process, and the switch of the spray shower 19 in the clamping assembly is controlled by the valve on the delivery pipe 21.

[0037] Example 3 The guide shaft support 13 is provided with a first through hole in the vertical direction and a second through hole in the horizontal direction. The guide shaft support 13 can be fixed at any position on the guide shaft 9. When the height of the spray unit needs to be adjusted, the bolt on the second through hole is loosened using a tool, moved to a specified position, and the bolt is passed from one side of the second through hole to the other side, and fixed with a matching nut.

[0038] There are two ways to rotate the spray unit. The first way is to rotate the hand wheel 1, which transmits the first bevel gear 3, the second bevel gear 4, the driving gear 6, the transmission gear 7, and the driven gear 8 to make the spray unit rotate in the horizontal direction; the second way is to rotate the control wheel 15, which transmits the third bevel gear 16 and the fourth bevel gear 17 to make the spray head rotate in the vertical direction.

[0039] By shaking the hand wheel 1 or the control wheel 15 to adjust the angle and generate different displacements, the spray unit can flexibly change the water spray angle. Whether it is a regular cabinet with a regular shape or a cabinet with a complex structure and various corners and slopes, the water flow can be accurately covered to the corresponding position by adjusting the angle, no longer limited to fixed angle water spray, which greatly expands the testable range.

[0040] For cabinets of different shapes and sizes, precise adjustment of height and depth can ensure that the water spray evenly and fully covers all parts of the cabinet, so that the test conditions such as water spray volume and water spray pressure received by each corner of the cabinet are relatively consistent, avoiding uneven conditions such as excessive or insufficient local water spray, thereby ensuring that the test results can truly reflect the actual waterproof performance of the cabinet in different positions, making the test results more reliable and of reference value.

[0041] Example 4 The present invention provides a manual spraying method for a charging pile, comprising the following steps: Turn the hand wheel 1 to make the first bevel gear 3 rotate synchronously through the adjustment shaft 12. The mutual meshing of the first bevel gear 3 and the second bevel gear 4 drives the second bevel gear 4 to rotate. The second bevel gear 4 drives the driving gear 6 sleeved on the same transmission shaft 5 to rotate. The driving gear 6 and the transmission gear 7 are meshed with each other, and the transmission gear 7 and the driven gear 8 are meshed with each other, driving the driven gear 8 to rotate. The driven gear 8 drives the spray unit on the guide shaft 9 to rotate, and the height of the spray unit on the guide shaft 9 is adjusted according to demand to test the waterproof performance of the cabinet.

[0042] Specifically, the shower head 19 is installed on one side of the support base 20, and the other side of the support base 20 is a delivery pipe 21. A valve is provided on the delivery pipe 21, and the valve can conveniently open or close the water flow of the shower head 19. When a water spray test is required, the valve is opened, and water flows to the shower head 19 through the delivery pipe 21 to realize the water spray operation. When the test is completed or water spraying is not required temporarily, the valve can be closed to stop water spraying immediately, thereby effectively controlling the water supply.

[0043] When testing the waterproof performance of the cabinet, push the manual spray device of the charging pile to the corresponding position and turn the hand wheel 1 or the control wheel 15. Turn the hand wheel 1, the first bevel gear 3 meshes with the second bevel gear 4 during the rotation process, the fixed bracket 23 is sleeved on the transmission shaft 5 and fixedly connected to the box body 2, the driving gear 6 is sleeved on the lower end of the transmission shaft 5, and rotates in the same direction as the second bevel gear 4, the driving gear 6 meshes with the transmission gear 7, and the transmission gear 7 also meshes with the driven gear 8 while the transmission gear 7 meshes with the driving gear 6. The spray unit is installed on the upper end of the driven gear 7 and sleeved on the guide shaft 9. Therefore, when the driven gear 7 rotates, the spray unit rotates to test the waterproof performance of the cabinet.

[0044] The guide shaft support 13 on the left side of the fixed base 14 is installed on the guide shaft 9 for fixing. The control wheel 15 is installed on the outside of the protective cover 26. When the control wheel 15 is rotated, the third bevel gear 16 in the protective cover 26 rotates in the same direction. The third bevel gear 16 and the fourth bevel gear 17 are meshed with each other. When the fourth bevel gear 17 rotates, the rolling wheel 18 rotates in the same direction, and the support seat 20 connected to the output shaft of the rolling shaft 18 also rotates in the same direction.

[0045] Through manual adjustment, the position of the spray unit on the guide shaft 9 can be adjusted at any time according to actual needs. Whether it is a spray test on the top, side or bottom of the cabinet, it can be easily achieved. This flexibility allows testers to conduct targeted tests on cabinets of different shapes and sizes to ensure that each part can be fully sprayed. It should be noted that regular maintenance is required to ensure its performance and reliability, such as loose connections, and timely maintenance and repairs.
