Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a fireproof charging pile. Background Art

[0002] Charging piles are important equipment for providing energy for electric vehicles. From a functional point of view, they can transmit AC or DC power to the battery of electric vehicles to meet the driving needs of the vehicles. Different types of charging piles have different charging powers and speeds. For example, AC charging piles have a relatively slow charging speed, which is suitable for charging when the vehicle is parked for a long time at home or in the office. DC charging piles have a faster charging speed and are suitable for public charging stations and other scenarios that require rapid power replenishment. From the perspective of application scenarios, charging piles are widely distributed in residential areas, commercial areas, public parking lots, highway service areas, etc.

[0003] Citing the Chinese publication number CN118457308A, the patent discloses a fireproof charging pile for new energy vehicles, specifically relating to the technical field of charging piles, including a main body, the side wall of which is provided with a plurality of heat dissipation holes arranged in a matrix, and a mounting frame, the mounting frame being arranged on the inner wall of the main body, and the heat dissipation holes are blocked or opened by a plurality of hinges arranged in a linear array and rotatably arranged thereon; the hinges are divided into a rotating part, an upper page part and a lower page part according to their functions, wherein: in the blocked state, the lower page part of the hinge of the upper level fits with the upper page part of the hinge of the next level, and the lower page part is arranged close to one side of the heat dissipation hole. The invention uses multiple hinges to drive together to block the heat dissipation holes arranged in a matrix, thereby forming a closed space inside the main body;

[0004] During the use of charging piles, each charging pile is connected by a power cord. When a fire occurs in one of the charging piles, the connection of the power cord will cause damage to more charging piles. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fire-proof charging pile to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fireproof charging pile, comprising a charging device, a charger is fixedly connected to the outer wall of the charging device, a power line is fixedly connected to the outer wall of the charging device, a bracket is fixedly connected to the outer wall of the charging device, and a blocking mechanism is fixedly connected to the outer wall of the bracket;

[0007] The blocking mechanism comprises:

[0008] A bearing, wherein the bearing is fixedly connected to the outer wall of the bracket;

[0009] A cutting blade, the outer wall of which is rotatably connected to the outer wall of the bearing;

[0010] The protruding teeth are fixedly connected to the outer wall of the cutting blade, and the cutting blade is in active contact with the power line.

[0011] Preferably, a sliding rod is inserted into the outer wall of the bracket, and a first spring is fixedly connected between the sliding rod and the bracket.

[0012] Preferably, the outer wall of the sliding rod is fixedly connected with a limiting tooth, and the limiting tooth is in movably contact with the raised tooth.

[0013] Preferably, the outer wall of the bracket is fixedly connected to a motor, and the outer wall of the motor is rotatably connected to a circular shaft. The circular shaft will drive the connecting plate and the swinging plate to rotate during the rotation. The rotation of the swinging plate will move the power cord, thereby driving the power cord to shake. When the power cord shakes, it is cut by the cutting blade. The power cord rubs against the cutting blade during the shaking process, and the power cord is quickly cut during the friction between the two, thereby ensuring that the fire is blocked.

[0014] Preferably, the outer wall of the circular shaft is fixedly connected with a toggle tooth. When the toggle tooth is rotated to the position of the cutting blade, the toggle tooth is toggled onto the raised tooth, thereby driving the cutting blade to rotate downward. The power cord can be cut during the rotation of the cutting blade. After the toggle tooth drives the cutting blade to rotate, the limiting tooth will be stuck on the raised tooth under the elastic compression of the first spring, thereby preventing the cutting blade from returning. By utilizing the intermittent contact between the toggle tooth and the raised tooth, the power cord can be cut. The outer skin of the power cord is elastic, so when the limiting tooth limits the cutting blade, the cutting blade can effectively cut off the power cord, thereby preventing the spread of fire and protecting other charging devices. The toggle tooth is in movably contact with the raised tooth, and the outer wall of the circular shaft is fixedly connected with a fan blade.

[0015] Preferably, a connecting plate is fixedly connected to the outer wall of the circular shaft, a swing plate is rotatably connected to the outer wall of the connecting plate, and the swing plate is in active contact with the power line.

[0016] Preferably, an auxiliary mechanism is fixedly connected to the outer wall of the bracket, and the auxiliary mechanism includes a limit frame, the outer wall of the limit frame is fixedly connected to the outer wall of the bracket, and the bottom of the limit frame is fixedly connected to a storage box, and an appropriate amount of fine sand is added to the storage box in advance. When the extrusion plate moves toward the extrusion bin, the gas passes through the storage box and then is discharged from the nozzle. When the airflow flows, it drives the fine sand to be sprayed out from the nozzle and the fine sand is sprayed onto the power line, thereby blocking the fire. By utilizing the spraying of fine sand, the fire can be effectively extinguished, ensuring the blocking of the fire.

[0017] Preferably, the bottom of the storage box is fixedly connected to an extrusion bin, and the top of the storage box is provided with a spray outlet, and part of the fine sand discharged from the spray outlet falls onto the power cord, and then part of it falls onto the limit frame again, and the accumulation of fine sand will bury the power cord to prevent the spread of fire. The burying of the power cord by fine sand can effectively prevent the fire and ensure the protection of other charging piles. When the circular shaft rotates, it will drive the toggle gear to rotate, and then fan the airflow toward the position of the charging device. The airflow will guide the fire on the charging device away from the position of the power cord, and then guide the fire. The outer wall of the bracket is fixedly connected to a telescopic machine, and the outer wall of the telescopic machine is movably connected to an extrusion plate, and the extrusion plate is inserted in the extrusion bin, and the outer wall of the extrusion plate is provided with an airflow hole, the inner wall of the airflow hole is fixedly connected to a second spring, and the outer wall of the second spring is fixedly connected to a blocking block.

[0018] The present invention provides a fire-proof charging pile, which has the following beneficial effects:

[0019] 1. The fireproof charging pile, when the toggle tooth rotates to the position of the cutting blade, the toggle tooth is toggled onto the raised tooth, thereby driving the cutting blade to rotate downward. The power cord can be cut during the rotation of the cutting blade. After the toggle tooth drives the cutting blade to rotate, the limiting tooth will be stuck on the raised tooth under the elastic compression of the first spring, thereby preventing the cutting blade from returning. The power cord can be cut by utilizing the intermittent contact between the toggle tooth and the raised tooth. The outer skin of the power cord is elastic, so when the limiting tooth limits the cutting blade, the cutting blade can effectively cut off the power cord, thereby preventing the spread of fire and protecting other charging devices.

[0020] 2. The fireproof charging pile will drive the connecting plate and the swinging plate to rotate during the rotation of the circular shaft. The rotation of the swinging plate will move the power cord, thereby driving the power cord to shake. When the power cord shakes, it will be cut by the cutting blade. The power cord will rub against the cutting blade during the shaking process. During the friction between the two, the power cord will be quickly cut, ensuring the blocking of the fire.

[0021] 3. For the fireproof charging pile, a proper amount of fine sand is added into the storage box in advance. When the extrusion plate moves toward the extrusion bin, the gas passes through the storage box and is discharged from the nozzle. The airflow drives the fine sand to be sprayed out from the nozzle and onto the power line, thereby blocking the fire. The fire can be effectively extinguished by utilizing the spraying of fine sand, ensuring the blocking of the fire.

[0022] 4. For this fireproof charging pile, part of the fine sand discharged through the nozzle falls onto the power cord, and then part of it falls onto the limit frame again. The accumulation of fine sand will bury the power cord to prevent the spread of fire. The burial of the power cord by fine sand can effectively prevent the fire and ensure the protection of other charging piles. When the circular shaft rotates, it will drive the toggle gear to rotate, and then fan the airflow toward the position of the charging device. The airflow will guide the fire on the charging device away from the position of the power cord, thereby guiding the fire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] For example, see Figure 1-5 The present invention provides a technical solution: a fireproof charging pile, comprising a charging device 1, a charger 2 is fixedly connected to the outer wall of the charging device 1, a power line 3 is fixedly connected to the outer wall of the charging device 1, a bracket 4 is fixedly connected to the outer wall of the charging device 1, and a blocking mechanism 5 is fixedly connected to the outer wall of the bracket 4;

[0035] The blocking mechanism 5 comprises:

[0036] A bearing 58, the bearing 58 is fixedly connected to the outer wall of the bracket 4;

[0037] A cutting blade 53, the outer wall of the cutting blade 53 is rotatably connected to the outer wall of the bearing 58;

[0038] The protruding teeth 54 are fixedly connected to the outer wall of the cutting blade 53 , and the cutting blade 53 is in active contact with the power line 3 .

[0039] A sliding rod 57 is inserted into the outer wall of the bracket 4 , and a first spring 56 is fixedly connected between the sliding rod 57 and the bracket 4 .

[0040] The outer wall of the slide rod 57 is fixedly connected with the limiting teeth 55 , and the limiting teeth 55 are in movable contact with the protruding teeth 54 .

[0041] The outer wall of the bracket 4 is fixedly connected to a motor 51 , and the outer wall of the motor 51 is rotatably connected to a round shaft 52 .

[0042] The outer wall of the circular shaft 52 is fixedly connected with a toggle tooth 59. When the toggle tooth 59 rotates to the position of the cutting blade 53, the toggle tooth 59 is toggled onto the raised tooth 54, thereby driving the cutting blade 53 to rotate downward. During the rotation of the cutting blade 53, the power cord 3 can be cut. After the toggle tooth 59 drives the cutting blade 53 to rotate, the limiting tooth 55 will be stuck on the raised tooth 54 under the elastic extrusion of the first spring 56, thereby preventing the cutting blade 53 from returning. By utilizing the intermittent contact between the toggle tooth 59 and the raised tooth 54, the power cord 3 can be cut. The outer skin of the power cord 3 is elastic, so when the limiting tooth 55 limits the cutting blade 53, the cutting blade 53 can effectively cut off the power cord 3, prevent the spread of fire, and thereby protect other charging devices 1. The toggle tooth 59 is in active contact with the raised tooth 54, and the outer wall of the circular shaft 52 is fixedly connected with a fan blade 6.

[0043] The outer wall of the circular shaft 52 is fixedly connected to the connecting plate 8. During the rotation of the circular shaft 52, the connecting plate 8 and the swinging plate 9 are driven to rotate. The rotation of the swinging plate 9 is driven to move onto the power cord 3, thereby driving the power cord 3 to shake. When the power cord 3 shakes, it is cut by the cutting blade 53. During the shaking process, the power cord 3 rubs against the cutting blade 53. During the friction between the two, the power cord 3 is quickly cut, ensuring the blocking of the fire. The outer wall of the connecting plate 8 is rotatably connected to the swinging plate 9, and the swinging plate 9 is in active contact with the power cord 3.

[0044] When in use, the charging device 1 is placed at the desired location, and the charger 2 charges the vehicle;

[0045] A fire detection device is provided in the charging device 1, and other devices are activated in case of fire;

[0046] Combined with Figure 5 and attached Figure 4 As shown, the motor 51 is powered on and started to drive the round shaft 52 to rotate. When the round shaft 52 rotates, it drives the toggle tooth 59 to rotate. When the toggle tooth 59 rotates to the position of the cutting blade 53, the toggle tooth 59 is toggled onto the raised tooth 54, thereby driving the cutting blade 53 to rotate downward. During the rotation of the cutting blade 53, the power cord 3 can be cut. After the toggle tooth 59 drives the cutting blade 53 to rotate, the limiting tooth 55 is clamped on the raised tooth 54 under the elastic compression of the first spring 56, thereby preventing the cutting blade 53 from returning. The elasticity of the first spring 56 is greater than the distance between the bracket 4 and the cutting blade 53, so the elasticity of the first spring 56 allows the limiting tooth 55 to be clamped in the raised tooth 54.

[0047] The circular shaft 52 will drive the connecting plate 8 and the swing plate 9 to rotate during the rotation. The swing plate 9 will be moved to the power cord 3, thereby driving the power cord 3 to shake. When the power cord 3 shakes, it will be cut by the cutting blade 53.

[0048] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0049] The outer wall of the bracket 4 is fixedly connected to an auxiliary mechanism 7, and the auxiliary mechanism 7 includes a limit frame 71. The outer wall of the limit frame 71 is fixedly connected to the outer wall of the bracket 4. The bottom of the limit frame 71 is fixedly connected to a storage box 72. A proper amount of fine sand is added to the storage box 72 in advance. When the extrusion plate 76 moves toward the extrusion bin 74, the gas passes through the storage box 72 and is discharged from the nozzle 73. When the airflow flows, it drives the fine sand to be sprayed out from the nozzle 73 and sprayed onto the power cord 3, thereby blocking the fire. By utilizing the spraying of fine sand, the fire can be effectively extinguished, ensuring the blocking of the fire.

[0050] The bottom of the storage box 72 is fixedly connected to an extrusion bin 74, and the top of the storage box 72 is provided with a spray outlet 73. Part of the fine sand discharged from the spray outlet 73 falls on the power cord 3, and then part of it falls on the limit frame 71 again. The accumulation of fine sand will bury the power cord 3 to prevent the spread of fire. The burial of the power cord 3 by the fine sand can effectively prevent the fire and ensure the protection of other charging piles. When the circular shaft 52 rotates, it will drive the toggle tooth 59 to rotate, and then fan the airflow toward the position of the charging device 1. The airflow will guide the fire on the charging device 1 away from the position of the power cord 3, thereby guiding the fire. The outer wall of the bracket 4 is fixedly connected to a telescopic machine 75, and the outer wall of the telescopic machine 75 is movably connected to an extrusion plate 76. The extrusion plate 76 is inserted in the extrusion bin 74. The outer wall of the extrusion plate 76 is provided with an air flow hole 78. The inner wall of the air flow hole 78 is fixedly connected to a second spring 77, and the outer wall of the second spring 77 is fixedly connected to a blocking block 79.

[0051] When in use, a proper amount of fine sand is added to the storage box 72 in advance, and the telescopic machine 75 is powered on to start the extrusion plate 76. When the extrusion plate 76 moves toward the extrusion chamber 74, the blocking block 79 is attached to the air flow hole 78 at this time, thereby preventing the gas from being discharged. The gas passes through the storage box 72 and then is discharged from the nozzle 73. When the air flow flows, the fine sand is driven to be sprayed out of the nozzle 73 and sprayed onto the power line 3, thereby blocking the fire. Then, when the extrusion plate 76 moves toward the outside of the extrusion chamber 74, the air flow pushes the blocking block 79 when passing through the air flow hole 78, and then the air flow enters the storage box 72.

[0052] The fine sand discharged through the nozzle 73 partially falls on the power cord 3, and then partially falls on the limit frame 71 again. The power cord 3 is close to the top of the limit frame 71, so the power cord 3 will be buried under the accumulation of fine sand to prevent the spread of fire. When the circular shaft 52 rotates, it will drive the toggle tooth 59 to rotate, and then fan the airflow toward the position of the charging device 1. The airflow will guide the fire on the charging device 1 away from the position of the power cord 3.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
