Description

Technical Field

[0001] This utility model relates to the field of charging pile protection technology, specifically to a charging pile protection device for new energy buses. Background Technology

[0002] A charging station for new energy buses is an electronic device that connects to electrical energy to charge new energy buses. Traditional charging stations for new energy buses include a charging station, control panel, charging gun, card reader area, protective plate, and two fixing plates. The card reader area is designed to ensure normal use for a long time. The large charging port of the bus is mostly located at the rear of the vehicle. When charging, the bus needs to reverse to a position close to the charging station. However, during the reversing and parking process, the bus is prone to collisions with the charging station due to limited visibility, which can damage it and affect charging operations. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for charging piles of new energy buses, which can prevent the rear of the bus from colliding with the charging pile when the bus is reversing and stopping, thereby avoiding damage to the charging pile and reducing cost losses.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A charging pile protection device for a new energy bus includes a concrete base higher than the ground, a support on the top surface of the concrete base, a protective canopy on the support, a charging pile below the protective canopy, and an anti-collision part on the long side of the concrete base. When the anti-collision part contacts the rear wheel of the bus, there is a gap between the rear of the bus and the charging pile.

[0006] In this design, a concrete base is poured on the hardened ground, with a steel mesh inside to improve its load-bearing capacity and service life. The top of the concrete base is higher than the ground, forming an upward-protruding platform. A bracket is bolted to the base, and a protective canopy is installed on the bracket. The charging pile is installed under the protective canopy, which protects the charging pile from sun and rain, extending its service life. When the bus reverses and stops, the rear wheels of the bus will contact the anti-collision part on the long side of the concrete base to stop the rear wheels, allowing the driver to turn off the bus. At this point, there is still a distance between the rear of the bus and the charging pile, thus preventing damage caused by a collision between the rear of the bus and the charging pile during reversing and stopping, reducing costs.

[0007] Optionally, the anti-collision part is made of rubber, the outer end face of the anti-collision part is arc-shaped, and the arc-shaped surface is coated with a polytetrafluoroethylene layer.

[0008] Optionally, the anti-collision part may be embedded with multiple steel plates, which are distributed in the area where the anti-collision part contacts the rear wheel of the bus.

[0009] Optionally, the protective canopy is distributed in an inverted V shape on both sides of the support frame, and a support rod is provided between the support frame and the protective canopy.

[0010] Optionally, the charging piles are distributed on both sides of the support, with multiple charging piles evenly spaced on the same side.

[0011] Optionally, a dry powder fire extinguisher is provided on the side of the concrete base, and a nozzle connected to the dry powder fire extinguisher is provided on the bottom of the protective shed.

[0012] Optionally, the bottom surface of the protective shed is also equipped with an identification module.

[0013] Optionally, the outlet of the dry powder fire extinguisher is connected to a main nozzle, and multiple branch nozzles are connected to the main nozzle. The number of branch nozzles corresponds to the number of charging piles. The nozzles are connected to the branch nozzles, and multiple nozzles are provided on the same branch nozzle.

[0014] Optionally, the main nozzle is equipped with a first solenoid valve, and the branch nozzle is equipped with a second solenoid valve.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, existing technology lacks any protective structure in front of the charging pile during the reversing and parking process of a bus. Due to limited visibility, the rear of the bus often collides with the charging pile during reversing, requiring repair or replacement and incurring costs. Furthermore, the charging pile is exposed to the elements, shortening its lifespan. In this solution, the protective canopy prevents the charging pile from being exposed to sun and rain, extending its lifespan. During the reversing and parking process, the concrete base protrudes above the ground, forming a barrier. The rear wheels of the bus contact the long side of the concrete base's anti-collision section, stopping the rear wheels and allowing the driver to turn off the bus. At this point, there is still a distance between the rear of the bus and the charging pile, preventing damage from a collision during reversing and parking, thus reducing costs.

[0023] Example

[0024] A charging pile protection device for a new energy bus includes a concrete base 1 that is higher than the ground. A support 4 is provided on the top surface of the concrete base 1. A protective canopy 5 is provided on the support 4. A charging pile 6 is provided below the protective canopy 5. An anti-collision part 12 is provided on the long side of the concrete base 1. When the anti-collision part 12 contacts the rear wheel 3 of the bus 2, there is a gap between the rear of the bus 2 and the charging pile 6.

[0025] In this embodiment, as Figure 1As shown, a concrete base 1 is poured on the hardened ground. The concrete base 1 contains a steel mesh to improve its load-bearing capacity and service life. The top surface of the concrete base 1 is higher than the ground, forming an upward-protruding platform. A bracket 4 is bolted to the base, and a protective canopy 5 is installed on the bracket 4. The charging pile 6 is installed below the protective canopy 5, which protects the charging pile 6 from sun and rain, extending its service life. When the bus 2 reverses and stops, the rear wheels 3 of the bus 2 contact the anti-collision part 12 on the long side of the concrete base 1 to stop the rear wheels 3, allowing the driver to turn off the bus 2. At this time, there is still a distance between the rear of the bus 2 and the charging pile 6, effectively preventing damage caused by a collision between the rear of the bus and the charging pile 6 during reversing and stopping, thus reducing costs. The distance between the rear of the bus and the charging pile 6 is also the driver's working area when charging the bus 2; this distance should not be too large, 1.5m-3m is sufficient.

[0026] Furthermore, the anti-collision part 12 is made of rubber, and the outer end face of the anti-collision part 12 is an arc-shaped surface, and a polytetrafluoroethylene layer 14 is coated on the arc-shaped surface.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the anti-collision part 12 is made of rubber. Rubber has a certain degree of resilience and can play a certain buffering role when the rear wheel 3 comes into contact with the impact. The end face of the anti-collision part 12 that contacts the rear wheel 3 is an arc-shaped surface. The arc-shaped surface is coated with a polytetrafluoroethylene layer 14. The polytetrafluoroethylene layer 14 has a low coefficient of friction and good wear resistance. In this way, after the rear wheel 3 comes into contact with the anti-collision part 12, if the driver does not stop in time, the polytetrafluoroethylene layer 14 can reduce the friction between the tire and the vehicle, reduce the probability of the rear wheel 3 hitting the concrete base 1 and causing the rear of the vehicle to collide with the charging pile 6, and further protect the charging pile 6.

[0028] Furthermore, multiple steel plates 13 are embedded in the anti-collision part 12, and the steel plates 13 are distributed in the area where the anti-collision part 12 contacts the rear wheel 3 of the bus 2.

[0029] Specifically, such as Figure 2 As shown, multiple steel plates 13 are embedded in the anti-collision part 12 by vulcanization. The steel plates 13 are distributed in the area where the rear wheel 3 contacts and collides with the anti-collision part 12, which can further improve the load-bearing capacity of the anti-collision part 12. The steel plates 13 can also be set to the same length as the anti-collision part 12.

[0030] Furthermore, the protective shed 5 is distributed in an inverted V shape on both sides of the support 4, and a support rod 9 is provided between the support 4 and the protective shed 5.

[0031] Specifically, such as Figure 1As shown, the protective canopy 5 has an inverted V-shaped cross-section. The coverage area of ​​the protective canopy 5 is larger than the area of ​​the concrete base 1. The height of the protective canopy 5 is greater than the height of the top surface of the bus 2 to avoid collisions. An inclined support rod 9 is provided between the support frame 4 and the protective canopy 5 to improve the stability of the protective canopy 5 in strong winds. The protective canopy 5 is made of common color steel plate or polycarbonate sheet.

[0032] Furthermore, the charging piles 6 are distributed on both sides of the support 4, with multiple charging piles 6 evenly spaced on the same side.

[0033] Specifically, such as Figure 2 As shown, charging piles 6 are distributed on both sides of the support 4, with multiple charging piles 6 evenly spaced on the same side. This allows multiple buses 2 to be charged simultaneously on both sides of the long side of the concrete base 1, improving the utilization rate of the concrete base 1.

[0034] Furthermore, a dry powder fire extinguisher 17 is provided on the side of the concrete base 1, and a nozzle 10 connected to the dry powder fire extinguisher 17 is provided on the bottom surface of the protective shed 5.

[0035] Furthermore, the bottom surface of the protective shed 5 is also equipped with an identification module 11.

[0036] Furthermore, the outlet of the dry powder fire extinguisher 17 is connected to a main nozzle 15, and multiple branch nozzles 7 are connected to the main nozzle 15. The number of branch nozzles 7 corresponds to the number of charging piles 6. The nozzles 10 are connected to the branch nozzles 7, and multiple nozzles 10 are provided on the same branch nozzle 7.

[0037] Furthermore, the main nozzle 15 is provided with a first solenoid valve 16, and the branch nozzle 7 is provided with a second solenoid valve 8.

[0038] Specifically, such as Figure 1 and Figure 2As shown, charging pile 6 is also prone to fire accidents during the charging process, which is also a challenge to the safety protection of charging pile 6. At present, the common practice is to place fire extinguishers near charging pile 6 and manually extinguish the fire in case of a small fire. However, since electrical fire accidents spread quickly, if the fire is not extinguished in time, it may cause an explosion accident. Therefore, in this utility model, a dry powder fire extinguisher 17 is installed on the side of the concrete base 1, and an identification module 11 is installed on the bottom surface of the protective shed 5. The identification module 11 is a camera used to capture whether a fire has occurred in the charging pile 6 below. A main nozzle 15 is laid on the concrete base. Since the charging piles 6 are distributed on both sides, there are two main nozzles 15 located on both sides of the support 4. A first solenoid valve 16 is installed on the main nozzle 15. Multiple branch nozzles 7 are connected to the main nozzle 15. One charging pile 6 corresponds to one branch nozzle 7. The branch nozzles 7 are fixed to the support 4 and the bottom surface of the protective shed 5 by buckles. Multiple nozzles 10 located below the protective shed 5 are provided on the branch nozzles 7. At the same time, a second solenoid valve 8 is also provided on the branch nozzles 7. The multiple nozzles 10 can cover the charging area between the charging pile 6 and the charging port of the bus 2. When the identification module 11 captures a fire scene, it sends a signal back to the control room. The control room then controls the first solenoid valve 16 and the corresponding second solenoid valve 8 to open. The high-pressure dry powder in the dry powder extinguishing tank 17 is then sprayed out through the main nozzle 15 and the corresponding branch nozzles 7, and finally sprayed out by the nozzle 10 to extinguish the fire on the charging pile 6, thus providing fire protection for the charging pile 6. Alternatively, perfluorohexanone extinguishing medium can be used to flush the fire into the extinguishing tank. To facilitate the identification of the charging pile 6 that is on fire, a camera can be installed above each charging pile 6. The camera only captures the corresponding charging pile 6 and the charging area below it. In this way, the second solenoid valve 8 is controlled to open when a fire scene is detected by the camera.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
