[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0021] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a new energy vehicle charging pile protection device, comprising a bottom plate 1, a charging pile body 2 is fixedly connected to the top of the bottom plate 1, a connecting pipe 3 is fixedly connected to the left side of the charging pile body 2, a charging slot 4 is opened on the surface of the charging pile body 2, a charging tube 5 is fixedly connected to the bottom of the inner wall of the charging slot 4, and a cutting mechanism 7 is arranged on the surface of the charging tube 5, and also includes: The cutting mechanism 7 includes a connecting ring 702, which is fixedly connected to the surface of the charging tube 5. A connecting groove 701 is provided on the surface of the connecting ring 702. The inner wall of the connecting groove 701 is slidably connected to a moving box 703 through a slider. A pushing component 709 is provided on the surface of the moving box 703. Cutting blocks 707 are slidably connected to both sides of the inner wall of the moving box 703 through sliders. An absorption capsule 708 is fixedly connected to the bottom of the inner wall of the cutting block 707. An absorption hole is provided on the surface of the absorption capsule 708. When the cutting block 707 cuts off the burning part of the charging gun barrel, the flame airflow generated by the combustion can be absorbed into the absorption capsule 708 through the absorption hole to prevent the flame airflow from pushing the cutting block 707 into the interior of the moving box 703. A connecting arm 704 is fixedly connected to the right side of the moving box 703. A pushing plate 705 is rotatably connected to the top of the inner wall of the connecting arm 704 through a rotating shaft. A pushing arm 706 is fixedly connected to the bottom of the pushing plate 705.

[0022] The pushing component 709 includes a shrinking ring 7091, one end of which is fixedly connected to the surface of the moving box 703, and the end of the shrinking ring 7091 away from the moving box 703 is fixedly connected to an absorption block 7092, and the right side of the absorption block 7092 is fixedly connected to a plug-in arm 7093, and plug-in plates are installed on both sides of the plug-in arm 7093. The volume of the plug-in plates is the same as the volume of the slots on both sides of the stretching block 8082. The plug-in plates on both sides are inserted into the slots on both sides of the stretching block 8082, so that the shrinking ring 7091 is fixed to the surface of the stretching block 8082, and the bottom of the inner wall of the plug-in arm 7093 is fixedly connected to a plug-in block 7094.

[0023] Working method of the first embodiment: when the charging gun is hung inside the charging tube 5, the tube mouth of the charging tube 5 ages and causes the voltage to increase, and after the current spark is generated inside the charging gun and the charging tube 5, the connection between the charging gun and the charging tube 5 will be burned, and the flame airflow generated by the burning will be ejected outward, and the ejected high-temperature gas will push the shrink ring 7091. After being pushed, the shrink ring 7091 will be retracted outward to the surface of the stretching block 8082, and will be plugged into the inside of the clamp 8083 through the plug-in block 7094. At the same time, the plug-in arms 7093 on both sides will extend into the slots on both sides of the stretching block 8082, thereby fixing the shrink ring 7091 and the stretching block 8082. At the same time, the flame airflow generated by the burning at the charging tube 5 will be absorbed by the absorption block 7092 into the moving box 7 03, the flame airflow will pop out the cut-off block 707 from the inside of the mobile box 703 to the outside. When the pop-up cut-off block 707 extends outward into the burning part of the charging gun, the flame airflow ejected outward will push the pushing plate 705 inside the connecting arm 704, so that the pushing plate 705 drives the pushing arm 706 at the bottom to rotate and contact the surface of the connecting ring 702. Since the pushing arm 706 has telescopic elasticity, the squeezing of the pushing arm 706 by the connecting ring 702 brings a thrust to the mobile box 703, and drives the mobile box 703 to rotate on the inner wall of the connecting ring 702, and the burning part of the charging gun is cut off by the cutting block 707 rotating in a ring, so as to prevent the burning range of the burning gun from expanding and spreading to the position of the charging gun barrel, causing greater fire damage.

[0024] Embodiment 2: The difference from embodiment 1 is as follows: Figure 5-Figure 6 The protective mechanism 6 includes a protective shell 601 fixedly connected to the surface of the charging pile body 2, the protective shell 601 is arranged on the surface of the charging slot 4, a receiving box 602 is fixedly connected to the top slot of the protective shell 601, a cooling component 603 is arranged on the surface of the receiving box 602, and a removal mechanism 8 is arranged on the surface of the protective shell 601.

[0025] The cooling assembly 603 includes a sliding cavity 6031 fixedly connected to the inner wall of the receiving box 602, the sliding cavity 6031 is fixedly connected to the surface of the charging pile body 2, the inner wall of the sliding cavity 6031 is slidably connected with an impact tube 6032, the inner wall of the sliding cavity 6031 is fixedly connected with a cooling tube 6033, a compression hole is provided at the bottom of the cooling tube 6033, when the impact tube 6032 extends into the compression hole, the condensed gas caused by squeezing the inside of the cooling tube 6033 by the impact tube 6032 is ejected outward, the inner wall of the cooling tube 6033 is slidably connected with a connecting rope 6034, the end of the connecting rope 6034 away from the inner wall of the cooling tube 6033 is fixedly connected with a sticking plate 6035, an installation hole is provided inside the cooling tube 6033, condensed gas is injected into the interior, when compressed, the condensed gas will be squeezed into the inside of the protective shell 601 through the connecting rope 6034, the sticking plate 6035 is fixedly connected to the surface slot of the receiving box 602.

[0026] Working method of the second embodiment: When the flame airflow generated by the combustion of the charging tube 5 flows into the interior of the receiving box 602 through the top slot of the protective shell 601, the flame airflow will flow into the inner wall of the sliding cavity 6031 through the surface of the sliding cavity 6031. When the flame airflow flows into the interior of the sliding cavity 6031 and accumulates to a certain amount, it will push the impact tube 6032 inside the sliding cavity 6031, so that the impact tube 6032 slides inside the sliding cavity 6031. When the impact tube 6032 slides to the top to the interior of the cooling tube 6033, the impact tube 6032 squeezes the interior of the cooling tube 6033. The pressure will form pressure, which will cause the condensed gas inside the cooling tube 6033 to be discharged outward through the connecting rope 6034 into the inside of the plate 6035. After the condensed gas flows into the inside of the connecting rope 6034, it will cause one end of the connecting rope 6034 to slide on the inner wall of the cooling tube 6033. Since the plate 6035 is connected to the surface of the receiving box 602, the condensed gas flowing out of the plate 6035 will flow into the inside of the protective shell 601 through the receiving box 602, and the burning position of the charging tube 5 will be extinguished by the condensed gas, thereby preventing the fire from spreading violently at the connection of the charging gun.

[0027] Example 3: Based on Example 1, continue to refer to Figure 7-Figure 8The removal mechanism 8 includes a sliding column 801, which is fixedly connected to the surface of the protective shell 601. The two sides of the sliding column 801 are rotatably connected with a covering plate 802 through a rotating shaft. The end of the covering plate 802 away from the sliding column 801 is fixedly connected with a displacement arm 803, and one side of the displacement arm 803 is fixedly connected with an absorption plate 806. The left side of the absorption plate 806 is fixedly connected with a storage cavity 807. The surface of the storage cavity 807 is provided with an absorption cavity. When the flame airflow flowing out of the discharge cavity tube 8081 is sprayed to the surface of the storage cavity 807, the flame airflow can be absorbed into the interior through the absorption cavity. The inner wall of the covering plate 802 is slidably connected with a pulling ring 804, and the end of the pulling ring 804 away from the inner wall of the covering plate 802 is fixedly connected with a plug-in ring 805. A plurality of friction blocks are installed inside the plug-in ring 805, which are fixed by friction with the surface of the charging gun barrel through the friction blocks. A stretching component 808 is provided at the bottom of the covering plate 802.

[0028] The stretching assembly 808 includes a discharge cavity tube 8081, which is fixedly connected to the bottom of the covering plate 802. The inner walls of the discharge cavity tube 8081 are slidably connected with stretching blocks 8082 via sliders. The bottom of the stretching block 8082 is fixedly connected with a snap clamp 8083. The right side of the stretching block 8082 is fixedly connected with a compression rope 8084. The compression rope 8084 has an air pressure cavity inside, and compressed gas is injected into the air pressure cavity. When subjected to external pressure, the compressed gas inside will be discharged into the covering plate 802 to push the pulling ring 804. The end of the compression rope 8084 away from the stretching block 8082 is fixedly connected to one side of the inner wall of the discharge cavity tube 8081.

[0029] Working method of the third embodiment: When the flame airflow generated by the combustion of the charging tube 5 will be ejected from the inside of the protective shell 601 to the outside, and at the same time, a part of the flame airflow will flow into the inside of the discharge cavity tube 8081, and the flame airflow will be introduced into the surface of the absorption plate 806 through the discharge cavity tube 8081, and the flame airflow will be absorbed by the storage cavity 807 on the surface of the absorption plate 806, and the shrink ring 7091 and the stretching block 8082 are connected to fix the covering plate 802 and the shrink ring 7091, so that the covering plate 802 can be fixed at an angle opening and closing outward, so as to avoid the connection The barrel will be stuck by the covering plate 802 when stretched outward and difficult to pull out When the shrink ring 7091 and the stretching block 8082 are fixed, the compression rope 8084 will be squeezed. After being squeezed, the compression rope 8084 will expand and contract inside the discharge cavity tube 8081. When the compression rope 8084 is stretched inward, air pressure will flow out from the inner wall of the covering plate 802, and the pulling ring 804 will be pushed outward by the outflowing air pressure. Because the charging gun and the charging tube 5 were fixed before, the charging gun barrel has been fixed to the inner wall of the plug-in ring 805. When the pulling ring 804 is pushed outward, the charging gun barrel will be pulled out from the inside of the protective shell 601 through the plug-in ring 805, preventing the burning part of the charging tube 5 from spreading to the surface of the charging gun barrel and causing a more intense fire.
