As energy replenishment devices, new energy vehicle charging piles are indispensable equipment as new energy vehicles gradually become popular. At the same time, the increasing popularity of charging piles has also attracted increasing attention to their fire-fighting functions.

[0003] The patent with patent announcement number CN113635798B discloses a new energy vehicle charging pile with a fire-fighting device, including a pile body, a charger and a connector. A control panel is installed on the outer side of the pile body by bolts, a side door is installed on the bottom of the pile body, a rain plate is welded on the top of the other side of the pile body, a fire hydrant is welded on the bottom of the pile body, a water pipe is arranged on one side of the fire hydrant, a support plate is welded on the inner side of the pile body, and a pillar is welded on the top of the support plate. The new energy vehicle charging pile with a fire-fighting device can extinguish the surrounding fire, ensure the safety of the charging place, ensure that the fire extinguisher is in a low temperature condition, avoid the temperature inside the pile body being too high due to exposure of the pile body to the sun, avoid the internal pressure being too high due to the heating of the fire extinguisher, ensure the safe placement of the fire extinguisher, avoid insufficient heat dissipation due to the high temperature outside the pile body, improve the heat dissipation efficiency of the charger, improve the working safety of the charger, and is suitable for charging and use of new energy vehicles.

[0004] However, the device still has some shortcomings: the device can quickly extinguish the surrounding fire through the built-in fire hydrants and fire extinguishers, but it is difficult for the device to perform indirect self-inspection on the charging pile itself when the high temperature weather outdoors in summer comes, resulting in the risk of overload and short circuit when the charging pile is overloaded under high temperature conditions. At this time, it is difficult for the device to extinguish its own fire in time to reduce losses. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a charging pile for new energy vehicles with a fire extinguishing device, which solves the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: A charging pile for new energy vehicles with a fire extinguishing device, comprising a base, a charging body is arranged on the top of the base, vents are opened on the left and right sides of the charging body, a protective shell is arranged on the outer wall of the base, and the top of the protective shell is designed as an inclined surface, a power supply body is arranged at the bottom of the inner wall of the charging body, and a partition is arranged on the top of the power supply body; An anti-damage device is arranged above the interior of the charging body, an anti-softening device is arranged on the back of the anti-damage device, and an anti-corrosion device is arranged at the bottom of the anti-softening device; The anti-damage device comprises an electric slide rail, the front of which is fixedly mounted on the front of the inner wall of the charging body, a transmission plate is slidably mounted inside the electric slide rail, a detection component is fixedly mounted on the outer wall of the transmission plate, a high-pressure spray gun is fixedly mounted on the detection component close to the front of the inner wall of the charging body through a flat plate, a spiral hose is connected and fixedly mounted on the top of the high-pressure spray gun, a carbon dioxide component is fixedly mounted on the top of the spiral hose, a cylinder is rotatably mounted inside the high-pressure spray gun, two inclined plates are fixedly mounted on the outer wall of the cylinder, and a A reciprocating screw rod, a sliding ring is movably installed through the outer wall of the reciprocating screw rod, a filter plate is fixedly installed at the bottom of the sliding ring, and the filter plate movably penetrates the outer wall of the reciprocating screw rod. A limit rod is fixedly installed at the bottom edge of the high-pressure spray gun, and a semicircular perforated plate is fixedly installed at the bottom of the filter plate. The charging body is located inside the protective shell, which protects the charging body and its top slope facilitates the flow of rainwater. When the charging body is subjected to regular fire self-inspection, the electric slide rail is started, and the electric slide rail drives the transmission plate to slide upward along its own interior and reset, and the transmission plate drives the detection component synchronously Movement, thereby expanding the detection range of the detection component. At the same time, the detection component drives the high-pressure spray gun to move synchronously by driving the flat plate upward. The high-pressure spray gun drives the spiral hose to shrink and reset synchronously. When the detection component detects that smoke or sparks appear inside the charging body after the charging body is overloaded in high temperature in summer, the detection component transmits the signal source to the intelligent module inside the carbon dioxide component. After the carbon dioxide component is started, the carbon dioxide gas is transported to the high-pressure spray gun through the spiral hose and sprayed out. Otherwise, the carbon dioxide component is not started. When the high-pressure spray gun is running, the gas flow between the inclined plates is caused to produce uneven pressure distribution through its sealed environment and high-pressure spray force, thereby generating a torque to cause the inclined plate to generate a rotating force. The inclined plate drives the cylinder to rotate inside the high-pressure spray gun, causing the inclined plate to disturb the carbon dioxide gas. At the same time, the cylinder drives the reciprocating screw to rotate. When the reciprocating screw rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the sliding ring, and the block constantly resists the reciprocating spiral groove to cause the sliding ring to slide down along the outer wall of the reciprocating screw and reset. At this time, the sliding ring drives the filter plate to move synchronously, and the limit rod limits the filter plate, and the filter plate drives the semicircular perforated plate to move synchronously.

When the self-test starts, the transmission plate drives the U-shaped plate to move upward and reset. The U-shaped plate drives the contact wheel to move and rub along the inner wall of the charging body. The contact wheel generates a rotational force through friction and starts to rotate. At the same time, the contact wheel will contact the sealing plate during its self-rotation and upward movement. The sealing plate causes its own hinge shaft to start rotating through the resistance force, and drives the bottom of the sealing plate to flip toward the axis of the charging body to seal and block the ventilation port of the charging body.

The above cooperation effectively expands the detection range of the detection component 43 to improve the accuracy of the detection result, and eliminates the fire hazard inside the charging body 2 through carbon dioxide gas, avoiding the charging body 2 from being damaged by fire due to overload and short circuit at high temperature, thereby improving the fire-fighting function of the charging body 2; the above cooperation helps to reduce the energy loss in the flow of carbon dioxide with the help of the rotation disturbance of the inclined plate 48, improve the overall transmission efficiency of the gas, and improve the elimination rate of sparks. At the same time, the filter plate 411 blocks external dirt, and guides the external floating dirt through the arc surface of the semicircular perforated plate 413, thereby ensuring the cleanliness of the inside of the high-pressure spray gun 44 and avoiding the obstruction of carbon dioxide transmission efficiency.

[0021] The carbon dioxide component 46 has an internal intelligent module. Two inclined plates 48 are relatively inclined and distributed on the outer wall of the cylinder 47 . The outer wall of the limiting rod 412 movably penetrates the interior of the filter plate 411 .

[0022] When in use, the charging body 2 is located inside the protective shell 21, the protective shell 21 protects the charging body 2 and its top slope is convenient for rainwater to flow. When the charging body 2 is subjected to regular fire self-inspection, the electric slide rail 41 is started, the electric slide rail 41 drives the transmission plate 42 to slide upward along its interior and reset, the transmission plate 42 drives the detection component 43 to move synchronously, thereby expanding the detection range of the detection component 43, and at the same time the detection component 43 drives the high-pressure spray gun 44 to move synchronously by driving the plate upward, the high-pressure spray gun 44 drives the spiral hose 45 to shrink and reset synchronously, when the detection component 43 detects When smoke or sparks appear inside the charging body 2 after overload operation at high temperature in summer, the detection component 43 transmits the signal source to the intelligent module inside the carbon dioxide component 46. After the carbon dioxide component 46 is started, the carbon dioxide gas is transported to the high-pressure spray gun 44 through the spiral hose 45 and sprayed out. Otherwise, the carbon dioxide component 46 is not started. The above cooperation effectively expands the detection range of the detection component 43 to improve the accuracy of the detection result, and eliminates the fire hazard inside the charging body 2 through the carbon dioxide gas, avoiding the fire damage caused by overload short circuit of the charging body 2 at high temperature and causing economic losses. This enhances the fire-fighting function of the charging body 2; when the high-pressure spray gun 44 is in operation, the gas flow between the inclined plates 48 is caused to produce uneven pressure distribution through its sealed environment and high-pressure spray force, thereby generating a torque to cause the inclined plate 48 to generate a rotating force, and the inclined plate 48 drives the cylinder 47 to rotate inside the high-pressure spray gun 44, causing the inclined plate 48 to disturb the carbon dioxide gas, and at the same time, the cylinder 47 drives the reciprocating screw 49 to rotate. When the reciprocating screw 49 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the sliding ring 410, and the block constantly resists the reciprocating spiral groove to enable the sliding ring 410 to move along the reciprocating screw 49 The outer wall slides downward and resets, at which time the sliding ring 410 drives the filter plate 411 to move synchronously, and the limiting rod 412 limits the filter plate 411, and the filter plate 411 drives the semicircular perforated plate 413 to move synchronously. The above coordination with the help of the rotational disturbance of the inclined plate 48 helps to reduce the energy loss in the flow of carbon dioxide, improve the overall transmission efficiency of the gas, and improve the elimination rate of sparks. At the same time, the filter plate 411 blocks external dirt and guides the external floating dirt through the arc surface of the semicircular perforated plate 413, thereby ensuring the internal cleanliness of the high-pressure spray gun 44 and avoiding obstruction of carbon dioxide transmission efficiency.

[0023] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-softening device 5; The anti-softening device 5 includes a support rod 51, a sealing plate 52, a U-shaped plate 53 and a plurality of abutment wheels 54. Both ends of the support rod 51 are fixedly mounted on the inner wall of the vent of the charging body 2. The sealing plate 52 penetrates inside and is hinged on the outer wall of the support rod 51. The U-shaped plate 53 is fixedly mounted on the outer wall of the transmission plate 42 near the axis of the charging body 2. The plurality of abutment wheels 54 are symmetrically and rotatably mounted on the inner wall of the U-shaped plate 53. Through the above cooperation, the charging body 2 has a good ventilation effect when it is not self-checked, and the internal temperature of the charging body 2 is prevented from being too high, which may cause the softening of the circuit surface, and the rubber oxidation speed may be accelerated due to this for a long time, so as to avoid the exposure of the circuit and increase the fire factor. At the same time, when extinguishing a fire, the sealing plate 52 seals the charging body 2 to isolate the external oxygen from entering, so as to further improve the fire extinguishing speed of carbon dioxide and improve the fire fighting effect.

[0024] A torsion spring is arranged between the inside of the sealing plate 52 and the support rod 51 , the U-shaped plate 53 is located at the back of the detection component 43 , the outer wall of the abutment wheel 54 contacts the inner wall of the charging body 2 , and the sealing plate 52 is located on the movement track of the abutment wheel 54 .

[0025] The anti-softening device 5 also includes a rotating rod 55, a hollow push plate 56, a wave plate 57 and a cooling assembly 58. Both ends of the rotating rod 55 are fixedly mounted on the center of the side of the friction wheel 54 close to the axis of the U-shaped plate 53. A reciprocating spiral groove is provided on the outer wall of the rotating rod 55. The hollow push plate 56 penetrates inside and is movably mounted on the outer wall of the rotating rod 55. The hollow push plate 56 is slidably connected to the inner wall of the U-shaped plate 53 on the side close to the transmission plate 42. The outer wall of the wave plate 57 is fixedly mounted inside the hollow push plate 56. The top of the cooling assembly 58 is fixedly mounted on the bottom of the transmission plate 42. The outer wall of the cooling assembly 58 is fixedly mounted on the side of the hollow push plate 56 close to the transmission plate 42. The above cooperation effectively expands the cold air coverage of the cooling assembly 58, and with the help of the horizontal sliding and wave surface of the wave plate 57, the carbon dioxide gas or the cold air emitted by the cooling assembly 58 is guided and disturbed, thereby improving the distribution uniformity of the two inside the charging body 2, and further avoiding the occurrence of fire.

[0026] When in use, the support rod 51 limits the sealing plate 52, and the sealing plate 52 is inclined to the charging body 2, so that the charging body 2 is ensured to have good ventilation effect when it is not self-checking, so as to prevent the heat energy emitted by the power supply body 3 from causing overheating inside the charging body 2. When the self-check starts, the transmission plate 42 drives the U-shaped plate 53 to move upward and reset, and the U-shaped plate 53 drives the contact wheel 54 to move and rub along the inner wall of the charging body 2. The contact wheel 54 generates a rotational force through friction and starts to rotate. At the same time, during the process of the contact wheel 54 rotating and moving upward, it will contact the sealing plate 52. The sealing plate 52 causes its own hinge axis to start rotating through the contact force, and drives the bottom of the sealing plate 52 to flip toward the axis direction of the charging body 2 to seal and block the ventilation port of the charging body 2. When the fire extinguishing work starts, the electric slide rail 41 automatically stops to cause the contact wheel 54 to always contact the sealing plate 52. Through the above cooperation, the charging body 2 has a good ventilation effect when it is not self-checking, so as to prevent the internal temperature of the charging body 2 from overheating. The high temperature causes the line surface to soften, which prevents the rubber from oxidizing faster due to long-term conditions, avoids the line being exposed and increases the factors causing fire. At the same time, when extinguishing a fire, the sealing plate 52 seals the charging body 2 to isolate the entry of external oxygen, further improving the fire extinguishing speed of carbon dioxide and improving the fire fighting effect. When the resistance wheel 54 rotates, it drives the rotating rod 55 to rotate. When the rotating rod 55 rotates, the reciprocating spiral groove on its outer wall limits the built-in hollow push plate 56, driving the hollow push plate 56 to slide backward along the outer wall of the rotating rod 55 and reset. The hollow push plate 56 drives the wave plate 57 to move synchronously. At the same time, the hollow push plate 56 drives the cooling assembly 58 to slide and reset along the bottom of the transmission plate 42. The above cooperation effectively expands the cold air coverage of the cooling assembly 58, and with the help of the horizontal sliding and wave surface of the wave plate 57, the carbon dioxide gas or the cold air emitted by the cooling assembly 58 is guided and disturbed, thereby improving the distribution uniformity of the two inside the charging body 2, and further avoiding the occurrence of fire.

The bottom of the drying box 61 is fixedly mounted on the top of the partition 31, and a cover plate is provided on the top of the drying box 61. The bottom of the telescopic rough plate 62 is slidably mounted on the bottom of the inner wall of the drying box 61. The outer wall of the sliding rod 63 penetrates and is fixedly mounted inside the fixed end of the telescopic rough plate 62. One end of the fixed rod 64 close to the axis of the drying box 61 is fixedly mounted on the outer wall of the fixed end of the telescopic rough plate 62. The rolling roller 65 penetrates and is rotatably mounted on the fixed rod 64. 4, the gas emitted by the desiccant is used to dry the inside of the charging body 2 to prevent the sudden increase of humidity inside the charging body 2 caused by summer rainstorms, thereby eroding the circuit and the power supply body 3, and preventing the circuit and the power supply body 3 from conducting electricity under the interference of water vapor and causing fire. At the same time, the rolling roller 65 rolls and presses the cover plate and improves the sealing between the cover plate and the drying box 61, preventing the cover plate from deforming after thermal expansion and contraction, thereby increasing the gap between itself and the drying box 61, and preventing the contact area between the desiccant and the air from increasing, thereby accelerating the volatilization speed.

The outer wall of the elastic sheet 67 contacts the arc surface of the semicircular block 66, and the hollow column 68 is fixedly mounted on the concave surface of the elastic sheet 67 on the side close to the telescopic rough plate 62. The inner wall of the drying box 61 is located on the movement trajectory of the hollow column 68. Through the above coordination, the vibration force is used to effectively prevent the desiccant particles from sticking together due to high temperature, and at the same time prevent the desiccant from being adhered to the outer wall of the telescopic rough plate 62 and being squeezed and difficult to fall off, thereby ensuring the individual uniformity of the desiccant and avoiding a reduction in the drying effect.

[0030] When in use, the hollow push plate 56 slides horizontally and resets, driving the telescopic end of the telescopic rough plate 62 to move synchronously, and the fixed end of the telescopic rough plate 62 drives the sliding rod 63 to slide synchronously inside the slide groove of the drying box 61, and the telescopic rough plate 62 disturbs the desiccant particles inside the drying box 61 through the roughness of its own outer wall. Then, when the hollow push plate 56 moves upward, it pulls the telescopic end of the telescopic rough plate 62 to extend upward synchronously. At the same time, during the sliding process of the telescopic rough plate 62, it drives the fixed rod 64 to move synchronously, and the fixed rod 64 drives the rolling roller 65 to slide synchronously along the top of the cover plate of the drying box 61 to generate friction. The rolling roller 65 causes itself to start rotating along the outer wall of the fixed rod 64 through the friction. Through the above cooperation, the gas emitted by the desiccant is used to dry the inside of the charging body 2 to avoid the sudden increase of internal moisture caused by summer rainstorms, thereby corroding the circuit and the power supply body 3, and avoiding the circuit and the power supply The main body 3 is electrically conductive under the interference of water vapor, thereby causing a fire. At the same time, the rolling roller 65 rolls and presses the cover plate and improves the sealing between the cover plate and the drying box 61, so as to prevent the cover plate from deforming due to thermal expansion and contraction, thereby increasing the gap between itself and the drying box 61, and preventing the contact area between the desiccant and the air from increasing, thereby accelerating the volatilization speed; when the telescopic rough plate 62 slides, it drives the semicircular block 66 to move synchronously, and when the semicircular block 66 moves horizontally, it is separated from the resistance and suppression of the elastic sheet 67. When the semicircular block 66 passes over the elastic sheet 67, the elastic sheet 67 drives the hollow column 68 to reciprocate and knock on the inner wall of the drying box 61 to generate vibration during the process of resetting by its own elastic force. Through the above cooperation, the vibration force is used to effectively prevent the desiccant particles from sticking together due to high temperature, and at the same time prevent the desiccant from being attached to the outer wall of the telescopic rough plate 62 and being squeezed and difficult to fall off, thereby ensuring the individual uniformity of the desiccant and avoiding a reduction in the drying effect.
