Detailed implementation manners

[0030] As Figures 1-10 shown, a protection device for a new energy vehicle charging station includes a column 2, the column 2 is arranged on the right side of the charging pile 1, the top surface of the column 2 is provided with a ceiling 3, an anti-collision mechanism 7 is arranged on the left side of the charging pile 1, second shielding mechanisms 5 are arranged on the front and rear sides of the ceiling 3, first shielding mechanisms 4 are arranged on the left and right sides of the second shielding mechanisms 5, an isolation room is formed between the two second shielding mechanisms 5 and the two first shielding mechanisms 4, and a fire extinguishing mechanism 6 is installed in the area corresponding to the isolation room on the bottom surface of the ceiling 3.

[0031] As Figure 3 、 5As shown in FIGS. 6, the second shielding mechanism 5 includes two guide rails 5-1. The two guide rails 5-1 are arranged in parallel below the ceiling 3. A sliding plate 5-2 is provided between the two guide rails 5-1. Traveling wheels 5-3 matching the guide rails 5-1 are installed on the left and right sides of the sliding plate 5-2. Above one of the guide rails 5-1, a first driving assembly is provided for driving the sliding plate 5-2 to move. The outside of the sliding plate 5-2 is connected to a fixing frame 5-8 through a connecting plate 5-7. A flip-type shielding plate 5-9 is provided on one side of the fixing frame 5-8. A second driving assembly for driving the flip-type shielding plate 5-9 is also provided on the fixing frame 5-8.

[0032] Specifically, the first driving assembly includes a second motor 5-4. The second motor 5-4 is installed above the guide rail 5-1 on the right side. A gear 5-5 is installed on the output shaft of the second motor 5-4. A rack 5-6 meshing with the gear 5-5 is connected to the top surface of the sliding plate 5-2. During use, the second motor 5-4 is started. The second motor 5-4 drives the gear 5-5 to rotate. The rotation of the gear 5-5 drives the rack 5-6 to move, thereby driving the sliding plate 5-2 to move along the guide rail 5-1.

[0033] The second driving assembly includes an electric push rod 5-10. The outside of the fixing frame 5-8 is connected to a first mounting seat 5-11. One end of the electric push rod 5-10 is hinged to the first mounting seat 5-11. A second mounting seat 5-12 is installed on the flip-type shielding plate 5-9. The working end of the electric push rod 5-10 is hinged to the second mounting seat 5-12. During use, since there is a vehicle parked in the charging space, if the flip-type shielding plate 5-9 is directly flipped, it will collide with the vehicle. Therefore, it is necessary to first use the sliding plate 5-2 to drive the flip-type shielding plate 5-9 to move outward. After the flip-type shielding plate 5-9 moves to the outside, the working rod of the electric push rod 5-10 contracts, driving the flip-type shielding plate 5-9 to flip from the horizontal state to the vertical state. At this time, the flip will not collide with the vehicle. After that, the sliding plate 5-2 drives the flip-type shielding plate 5-9 to reset, so that the flip-type shielding plate 5-9 approaches the limit post 4-1 to form a shielding wall in the front-rear direction.

[0034] If the new energy electric vehicle catches fire or catches fire, the two second shielding mechanisms 5 work simultaneously to shield the front and rear sides; the specific steps are: start the second motor 5-4, the second motor 5-4 drives the gear 5-5 to rotate, the rotation of the gear 5-5 drives the rack 5-6 to move, thereby driving the sliding plate 5-2 to move along the guide rail 5-1, after the sliding plate 5-2 moves to the outermost side, the working rod of the electric push rod 5-10 contracts, driving the flip shielding plate 5-9 to flip from a horizontal state to a vertical state, and then, the second motor 5-4 rotates in the opposite direction, driving the sliding plate 5-2 to reset, so that the flip shielding plate 5-9 is close to the limit column 4-1 to shield the front side. In this way, the other second shielding mechanism 5 shields the rear side.

[0035] like Figure 7 , 8 As shown, the first shielding mechanism 4 includes two limit columns 4-1, the two limit columns 4-1 are symmetrically arranged front to back, and openings are provided on opposite sides of the two limit columns 4-1. A foldable shielding plate 4-2 is provided inside the limit columns 4-1, and a shielding curtain 4-4 is provided above the foldable shielding plate 4-2. The shielding curtain 4-4 is connected to the bottom surface of the ceiling 3, and the shielding curtain 4-4 is located on the inner side of the foldable shielding plate 4-2. The shielding curtain 4-4 shields the space above the foldable shielding plate 4-2. When the foldable shielding plate 4-2 is unfolded, the foldable shielding plate 4-2 will not collide with the ceiling 3. A driving device 4-3 for driving the foldable shielding plate 4-2 is provided on the right side of the limit column 4-1.

[0036] Specifically, the foldable shielding plate 4-2 includes a rotating shaft 4-2-1, which is rotatably mounted at the bottom of the limiting column 4-1. The rotating shaft 4-2-1 is equipped with eight folding blades 4-2-2. The folding blade 4-2-2 located at the bottom is fixedly connected to the rotating shaft 4-2-1, and the remaining seven folding blades 4-2-2 are movably connected to the rotating shaft 4-2-1. The eight folding blades 4-2-2 are fully unfolded to form the foldable shielding plate 4-2. The upper part of the limiting column 4-1 is equipped with a second limiting groove 4-2-4. The folding blades 4-2 -2 is provided with a first limiting groove 4-2-2-1 on the inner wall, and the second limiting groove 4-2-4 and the eight first limiting grooves 4-2-2-1 form a 90-degree arc groove, and a limiting wheel 4-2-3 is installed on the side of the folding blade 4-2-2 close to the limiting column 4-1, and the limiting wheel 4-2-3 on the first folding blade 4-2-2 close to the limiting column 4-1 moves along the second limiting groove 4-2-4, and the limiting wheels 4-2-3 on the other folding blades 4-2-2 move along the first limiting groove 4-2-2-1 located on the upper side thereof.

[0037] The driving device 4-3 includes a first motor 4-3-1. A speed reducer 4-3-2 is installed at the output end of the first motor 4-3-1. The output end of the speed reducer 4-3-2 is connected to the rotating shaft 4-2-1. A protective shell is provided outside the first motor 4-3-1 and the speed reducer 4-3-2.

[0038] During use, the first motor 4-3-1 and the speed reducer 4-3-2 operate to drive the rotation of the rotating shaft 4-2-1. When the rotating shaft 4-2-1 rotates, it drives the folding blade 4-2-2 at the bottom to unfold downward. Due to the presence of the limit wheel 4-2-3, the other seven folding blades 4-2-2 unfold accordingly. After the eight folding blades 4-2-2 are fully unfolded, a folding baffle 4-2 is formed. When the two symmetrically arranged folding baffles 4-2 are both unfolded, the first shielding mechanism 4 is fully opened.

[0039] As Figure 9 As shown, the fire extinguishing mechanism 6 includes a number of dry powder storage tanks 6-1. The number of dry powder storage tanks 6-1 is connected to the ceiling 3 through brackets. A dry powder spraying pipe 6-2 is connected to the dry powder storage tank 6-1. A fire extinguishing nozzle 6-3 is installed at the end of the dry powder spraying pipe 6-2. A valve is installed at the outlet of the dry powder storage tank 6-1. When a new energy electric vehicle catches fire or burns, the valve opens, and dry powder is sprayed downward through the fire extinguishing nozzle 6-3 to extinguish the fire.

[0040] As Figure 10As shown in the figure, the anti-collision mechanism 7 includes a fixed frame 7-1, which is arranged below the ground. The top surface of the fixed frame 7-1 is flush with the ground. A limiting plate 7-3 is connected inside the fixed frame 7-1. There is an accommodation cavity on the left side of the limiting plate 7-3. Two mounting plates 7-2 are connected to the top surface of the limiting plate 7-3. A rotating frame 7-4 is rotatably installed between the fixed frame 7-1 and the mounting plate 7-2. An energy absorption block 7-8 is installed on the left side of the rotating frame 7-4. The energy absorption block 7-8 is a metal thin-walled member. A number of grooves 7-8-1 are provided on the energy absorption block 7-8. An outer tube 7-5 is rotatably installed between the two mounting plates 7-2. The middle position at the top of the rotating frame 7-4 is connected with an inner tube 7-6. The bottom end of the inner tube 7-6 is inserted into the outer tube 7-5 and positioned by a positioning pin 7-7. During use, pull out the positioning pin 7-7, rotate the rotating frame 7-4 to the horizontal position, and the energy absorption block 7-8 enters the accommodation cavity, so that the rotating frame 7-4 is located inside the fixed frame 7-1, and the whole anti-collision mechanism is underground, which does not affect the inspection and maintenance of the charging pile 1. Rotate the rotating frame 7-4 to the vertical position, and use the positioning pin 7-7 to fix the positions of the inner tube 7-6 and the outer tube 7-5. At this time, the rotating frame 7-4 is on the left side of the charging pile 1, which can protect the charging pile 1. When a vehicle drives into the charging space, if the driving is improper and the vehicle collides with the energy absorption block 7-8, the energy absorption block 7-8 will be wrinkled and deformed along the position of the groove 7-8-1 during a strong collision, and the energy is absorbed through plastic deformation to reduce the damage of the impact force to the rotating frame 7-4. The outer tube 7-5 supports the rotating frame 7-4 to improve the anti-collision ability.

[0041] The using process of the present invention is as follows:

[0042] During the process of parking a new energy electric vehicle in the charging space for charging, if the new energy electric vehicle catches fire or has a fire, the two second shielding mechanisms 5 work simultaneously to shield the front and rear sides; the two first shielding mechanisms 4 are deployed to shield the left and right sides. The two second shielding mechanisms 5 and the two first shielding mechanisms 4 will form an isolation room to protect the charging pile 1; the fire extinguishing mechanism 6 sprays dry powder into the isolation room to extinguish the fire.

[0043] The above embodiments are only described for the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
