Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, specifically a fire extinguisher for new energy charging stations. Background Technology

[0002] New energy charging stations are locations that provide charging services for electric vehicles. They typically have a large number of public charging piles. Electric vehicle charging stations are divided into slow charging and fast charging; slow charging uses AC power, and fast charging uses DC power. Lithium-ion batteries have become the preferred power battery for new energy vehicles. However, lithium-ion batteries can experience problems such as insufficient negative electrode capacity, excessive moisture content, reactions with lithium leading to overcharging, gas generation, internal short circuits causing high-current discharge, excessive heat, and damage to the separator. Overcharging can also lead to fires or explosions. Therefore, fire extinguishers are placed at new energy charging stations for timely fire suppression in case of fire.

[0003] In existing technologies, conventional fire extinguishers used in new energy charging stations are often placed directly next to the charging piles. Prolonged exposure to the elements can lead to accelerated corrosion of the fire extinguisher pipes, reducing their lifespan. There is also the risk of accidental contact, which can damage them and render them unusable. In addition, some larger fire extinguishers are not easy for women with less strength to carry and use, making them very inconvenient. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model discloses a fire extinguisher for a new energy charging station, including a fire extinguisher body 1. A moving mechanism 2 is fixedly installed on the lower surface of the fire extinguisher body 1. Anti-collision mechanisms 3 are evenly installed circumferentially on the outer surface of the fire extinguisher body 1. A control valve 4 is fixedly installed on the upper surface of the fire extinguisher body 1. A material belt 5 is connected to the right side of the control valve 4. A discharge head 6 is fixedly installed on the other end of the material belt 5, and the material belt 5 is wound around the control valve 4. A sealing cover 8 is installed on the upper surface of the fire extinguisher body 1 through a connecting mechanism 7. An exhaust mechanism 9 is provided on the left side wall of the sealing cover 8. A handle 10 is installed on the left side of the upper surface of the sealing cover 8.

[0022] Specifically, the moving mechanism 2 includes rollers 201 and support feet 202. There are two rollers 201, which are fixedly installed at the front and rear positions of the left edge of the lower surface of the fire extinguisher body 1. There are two support feet 202, which are fixedly installed at the front and rear positions of the right edge of the lower surface of the fire extinguisher body 1.

[0023] In this embodiment, the lower surface of the support foot 202 is 0.5cm lower than the lower surface of the roller 201. The roller 201 and the support foot 202 are supported on the ground at the same time, so that the fire extinguisher body 1 is placed stably and tilted towards the roller 201. The support foot 202 is raised and does not contact the ground, which facilitates the movement of the fire extinguisher body 1.

[0024] Specifically, the anti-collision mechanism 3 includes a rubber strip 301 and a reflective sticker 302. The rubber strip 301 is uniformly fixedly installed on the outer surface of the fire extinguisher body 1 along the circumference, and the reflective sticker 302 is fixedly pasted on the side of the rubber strip 301 away from the fire extinguisher body 1.

[0025] In this embodiment, the rubber strip 301 has a cushioning and shock-absorbing effect, making the fire extinguisher body 1 less susceptible to damage from impacts. The reflective sticker 302 has a reflective function, increasing nighttime reflectivity, making it less likely to be bumped, and easy to find.

[0026] Specifically, the connecting mechanism 7 includes a cylinder 701, an external thread 702, and an internal thread 703. The cylinder 701 is fixedly installed on the upper surface of the fire extinguisher body 1. The outer surface of the cylinder 701 is provided with an external thread 702, and the inner wall of the sealing cover 8 corresponding to the external thread 702 is provided with an internal thread 703.

[0027] In this embodiment, the internal thread 703 on the inner wall of the sealing cover 8 engages with the external thread 702 on the outer surface of the cylinder 701, so that the sealing cover 8 is connected and fixed to the cylinder 701, and the sealing cover 8 covers the control valve 4, the material belt 5 and the discharge head 6.

[0028] Specifically, a rubber sealing ring 11 is fixedly installed on the lower surface of the sealing cover 8.

[0029] In this embodiment, the rubber sealing ring 11 improves the sealing effect between the lower surface of the sealing cover 8 and the upper surface of the fire extinguisher body 1.

[0030] Specifically, the exhaust mechanism 9 includes an exhaust airbag 901, a one-way intake valve 902, and a one-way exhaust valve 903. The exhaust airbag 901 is fixedly embedded in the left side wall of the sealing cover 8. The one-way intake valve 902 is fixedly installed on the front side of the exhaust airbag 901. The one-way exhaust valve 903 is fixedly installed on the upper surface of the exhaust airbag 901. The upper surface of the one-way exhaust valve 903 is connected to the outside.

[0031] In this embodiment, the exhaust bladder 901 is repeatedly pressed, causing the gas inside the sealing cover 8 to enter the exhaust bladder 901 through the one-way inlet valve 902, and then be discharged through the one-way outlet valve 903 on the upper surface of the exhaust bladder 901, so that a near-vacuum is formed inside the sealing cover 8, reducing the oxygen content and effectively preventing the control valve 4, the material belt 5 and the discharge head 6 from being oxidized and corroded.

[0032] During use, the sealing cover 8 engages with the external thread 702 on the outer surface of the cylinder 701 via the internal thread 703 in the connecting mechanism 7, thus connecting and fixing the sealing cover 8 to the cylinder 701. The sealing cover 8 covers the control valve 4, the conveyor belt 5, and the discharge head 6. Then, the exhaust bladder 901 in the exhaust mechanism 9 is repeatedly pressed, causing the gas inside the sealing cover 8 to enter the exhaust bladder 901 through the one-way inlet valve 902, and then exit through the one-way outlet valve 903 on the upper surface of the exhaust bladder 901. This creates a near-vacuum inside the sealing cover 8, reducing oxygen content and effectively preventing oxidation and corrosion of the control valve 4, conveyor belt 5, and discharge head 6, extending their service life. (This is achieved through the anti-collision mechanism.) The rubber strip 301 in structure 3 has a cushioning and shock absorption effect, making the fire extinguisher body 1 less susceptible to damage from impacts. The reflective sticker 302 has a reflective function, increasing nighttime reflectivity, making it less likely to be bumped and easier to find. When the fire extinguisher needs to be used, hold the handle 10 and move the fire extinguisher body 1 toward the roller 201 in the moving mechanism 2. The support foot 202 is raised and does not contact the ground, making it easy to move the fire extinguisher body 1. Remove the sealing cover 8, remove the discharge head 6 and the material belt 5, and open the control valve 4 to allow the dry powder in the fire extinguisher body 1 to be sprayed out through the material belt and the discharge head 6 for fire extinguishing. It is convenient for people of different strengths to move and use, and is highly practical.

[0033] In summary, this fire extinguisher for new energy charging stations features enhanced sealing protection for control valve 4 and conveyor belt 5, reducing oxidation and corrosion, extending service life, and adding anti-collision and reflective functions. It is less prone to damage from impacts, easier to find in low light conditions, and more portable, making it convenient for different groups of people to use. It is highly practical.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
